Item Disinformation on Youtube: A Dataset of Youtube Comments on Videos Related to Claims Made by Trump and Vance on Haitian Immigrants(2025-02-12) Omizo, Ryan M.The YouTube Disinformation Comments Corpus provides 71,025 comments to 23 YouTube videos posted by US news organizations on the false claim that Haitian immigrants in Springfield, Ohio were stealing and eating neighborhood pets, which was picked up and amplified by the 2024 Republican presidential ticket of Donald Trump and J.D. Vance. Additionally, the YouTube Disinformation Comments Corpus features metadata associated with each YouTube video, including video titles, descriptions, transcripts, like counts, and YouTube content tags. This dataset is useful for people studying (1) natural language processing, (2) network textual analysis, (3) the circulation of dis- and misinformation on YouTube; (4) the reception of dis- and misinformation on YouTube; (5) news framing effects on YouTube and (6) public discussions of US immigration. TFIDF analysis is used to provide an overview of the variations across comment data.Item Challenge in the Charcas: Bolivia in the “Global Cold War” Geopolitical Imagination(2024-03-23) VanSise, Casey F.Assorted observers of geopolitics have long been dismissive of Bolivia's significance within the international order, regarding it as a marginal "backwater" polity relative to other countries throughout the world and even among South American states. This common characterization of Bolivia's ostensibly wanting importance on the world stage is belied by the extent to which a variety of geostrategists valued the Andean nation's territorial and resource endowments as vital to shifting the balance of power within the Western Hemisphere. In the era spanning from the 1952 Revolution to the 1980 "Cocaine Coup" in Bolivia taking place in the midst of the Cold War, actors associated with multiple foreign powers would undertake interventions by diplomatic, financial, intelligence, and military means in an effort to shape that country's political trajectory to their perceived advantage. These foreign interventionists in Bolivia would include not only those affiliated with the United States (one of the two Cold War superpowers and the primary hegemon of the Western Hemisphere), but also those affiliated with other hemispheric states such as Cuba, Brazil, Argentina, and Chile, and even extra-hemispheric states such as Israel and South Korea. Among those who played a crucial role in prioritizing and enacting interventions in Bolivia were individuals as varied as John Foster Dulles, Ernesto “Che” Guevara, Lewis A. Tambs, Golbery do Couto e Silva, Bo Hi Pak, and Guillermo Suárez Mason, several of whom described Bolivia as the "Charcas Heartland," adapting the geostrategic thought of Halford Mackinder regarding the Eurasian continent to South American circumstances.Item Exploring Music-Based Interventions for Executive Functioning and Emotional Well-Being in Stroke Rehabilitation: A Scoping Review(2024-11-27) Pfeiffer, Camila F.; Magee, Wendy L.; Fulop, Rebecca; Nace, Travis; Castro, Candela; Iturri, Agustina; Franceschi, Jimena; Echauri, Gabriela; Gassull, Liliana; Julieta Russo, MaríaPurpose: Stroke is one of the leading causes of disability with life-long implications requiring assessment and treatment of several functional domains. This review identifies the results from research into music-based interventions (MBIs), including music therapy (MT), for executive functions (EFs) and emotional well-being (EWB) in adults with stroke and highlights opportunities for clinical practice and future research. Methods: APA PsycInfo (EBSCOhost), and CINAHL (EBSCOhost) were searched, in addition to grey literature. Results: A total of 49 studies were included and encompassed experimental, analytic, and descriptive observational studies, and case reports, involving a total of 1663 participants. In total, 32 studies included MT interventions, and 17 were MBIs. EFs were an outcome in 20.41%, and EWB in 61.22% of studies, for which active interventions were the most utilized. Overall, 73.47% of the studies reported positive results. Conclusions: This scoping review indicates that music interventions can be beneficial for the improvement of different aspects of EFs and EWB at different stages of stroke recovery. Further research may benefit clinical practice by including standardized protocols, outcome and self-reported measures, and brain imaging data to determine the effects of interventions and support evidence-based decisions for treatment policies for stroke survivors.Item Granulomatous cheilitis - is there a role for allergen screening and avoidance?(2023-01-31) Kern, Jessica A.; Amanullah, Amir; Sahni, Dev R.; Mathis, Jason G.; Hull, Christopher M.; Powell, Douglas L.; Secrest, Aaron M.Item Craniofacial Development Is Fine-Tuned by Sox2(2023-01-31) Mandalos, Nikolaos Panagiotis; Dimou, Aikaterini; Gavala, Maria Angeliki; Lambraki, Efstathia; Remboutsika, Eumorphia; Aging + Cardiovascular Discovery Center (Temple University)The precise control of neural crest stem cell delamination, migration and differentiation ensures proper craniofacial and head development. Sox2 shapes the ontogeny of the cranial neural crest to ensure precision of the cell flow in the developing head. Here, we review how Sox2 orchestrates signals that control these complex developmental processes.Item Satire without borders: the age-moderated effect of one-sided versus two-sided satire on hedonic experiences and patriotism(2023-01-31) Boukes, Mark; LaMarre, HeatherThe differential satire effects across domestic and foreign audiences are largely unknown; yet, this is of growing relevance as political satire increasingly reaches international audiences. A two-country experiment was conducted in which satirical stimuli from the Netherlands with either a one-sided (only targeting the United States) or two-sided humorous message (targeting both the U.S. and the Netherlands) was presented to a domestic (in-group) or foreign (out-group) audience. Specifically, this study examines political satire’s differential emotional and attitudinal impact on audiences located in the country-of-production (Netherlands) or abroad (U.S.). Results show that satire sidedness uniformly influenced hedonic enjoyment: compared to two-sided satire, one-sided satire elicited negative emotions and decreased positive emotions for both the in-group (Dutch) and the out-group (U.S.) audience. Yet, satire differentially affected patriotic attitudes. This effect was moderated by country and age: younger U.S. citizens became less patriotic after exposure to the one-sided satire that targeted their country and decreased their positive emotions; older U.S. citizens, in contrast, became more patriotic after exposure to this one-sided satire that particularly increased their negative emotions. The Dutch audience’s level of patriotism remained stable irrespective of satire sidedness. Altogether, this study demonstrates how humor type, country-of-reception, and age matter for satire effects.Item Conservation Practices for Personal Protective Equipment: A Systematic Review with Focus on Lower-Income Countries(2023-01-31) Thiel, Cassandra L.; Sreedhar, Pallavi; Silva, Genevieve S.; Greene, Hannah C.; Seetharaman, Meenakshi; Durr, Meghan; Roberts, Timothy; Vendanthan, Rajesh; Lee, Paul H.; Andrade, Gizely; El-Shahawy, Omar; Hochman, Sarah E.During the start of the COVID-19 pandemic, shortages of personal protective equipment (PPE) necessitated unprecedented and non-validated approaches to conserve PPE at healthcare facilities, especially in high income countries where single-use disposable PPE was ubiquitous. Our team conducted a systematic literature review to evaluate historic approaches for conserving single-use PPE, expecting that lower-income countries or developing contexts may already be uniquely conserving PPE. However, of the 50 included studies, only 3 originated from middle-income countries and none originated from low-income countries. Data from the included studies suggest PPE remained effective with extended use and with multiple or repeated use in clinical settings, as long as donning and doffing were performed in a standard manner. Multiple decontamination techniques were effective in disinfecting single use PPE for repeated use. These findings can inform healthcare facilities and providers in establishing protocols for safe conservation of PPE supplies and updating existing protocols to improve sustainability and overall resilience. Future studies should evaluate conservation practices in low-resource settings during non-pandemic times to develop strategies for more sustainable and resilient healthcare worldwide.Item Interruptions to HIV Care Delivery During Pandemics and Natural Disasters: A Qualitative Study of Challenges and Opportunities From Frontline Healthcare Providers in Western Kenya(2023-01-30) Tran, Dan; Ching, Jennifer; Kafu, Catherine; Wachira, Juddy; Koros, Hillary; Venkataramani, Maya; Said, Jamil; Pastakia, Sonak D.; Galárraga, Omar; Genberg, Becky L.During public health crises, people living with HIV (PLWH) may become disengaged from care. The goal of this study was to understand the impact of the COVID-19 pandemic and recent flooding disasters on HIV care delivery in western Kenya. We conducted ten individual in-depth interviews with HIV providers across four health facilities. We used an iterative and integrated inductive and deductive data analysis approach to generate four themes. First, increased structural interruptions created exacerbating strain on health facilities. Second, there was increased physical and psychosocial burnout among providers. Third, patient uptake of services along the HIV continuum decreased, particularly among vulnerable patients. Finally, existing community-based programs and teleconsultations could be adapted to provide differentiated HIV care. Community-centric care programs, with an emphasis on overcoming the social, economic, and structural barriers will be crucial to ensure optimal care and limit the impact of public health disruptions on HIV care globally.Item Mineral surface area in deep weathering profiles reveals the interrelationship of iron oxidation and silicate weathering(2023-01-31) Fisher, Beth A.; Yoo, Kyungsoo; Aufdenkampe, Anthony K.; Nater, Edward A.; Feinberg, Joshua M.; Nyquist, JonathanMineral specific surface area (SSA) increases as primary minerals weather and restructure into secondary phyllosilicate, oxide, and oxyhydroxide minerals. SSA is a measurable property that captures cumulative effects of many physical and chemical weathering processes in a single measurement and has meaningful implications for many soil processes, including water-holding capacity and nutrient availability. Here we report our measurements of SSA and mineralogy of two 21 m deep SSA profiles at two landscape positions, in which the emergence of a very small mass percent (<0.1 %) of secondary oxide generated 36 %–81 % of the total SSA in both drill cores. The SSA transition occurred near 3 m at both locations and did not coincide with the boundary of soil to weathered rock. The 3 m boundary in each weathering profile coincides with the depth extent of secondary iron oxide minerals and secondary phyllosilicates. Although elemental depletions in both profiles extend to 7 and 10 m depth, the mineralogical changes did not result in SSA increase until 3 m depth. The emergence of secondary oxide minerals at 3 m suggests that this boundary may be the depth extent of oxidation weathering reactions. Our results suggest that oxidation weathering reactions may be the primary limitation in the coevolution of both secondary silicate and secondary oxide minerals. We value element depletion profiles to understand weathering, but our finding of nested weathering fronts driven by different chemical processes (e.g., oxidation to 3 m and acid dissolution to 10 m) warrants the recognition that element depletion profiles are not able to identify the full set of processes that occur in weathering profiles.Item Economías simbólicas del costumbrismo español: pintoresquismo y tipos del «hablador/observador»(2023-01-31) Fernandez Cano, Jesus ManuelEste artículo pretende problematizar con las nociones que la crítica ha entendido como centrales en el estudio del costumbrismo, a saber: si su origen se remonta o no al s. XVIII, si es un movimiento eminentemente conservador y si guarda una relación de tipo historicista con movimientos posteriores como el realismo. Desde una perspectiva marxista se defenderá que el costumbrismo responde a la emergencia de una clase media subsumida en los entramados ideológicos barrocos; y, por ende, incapaz de emanciparse de las prefiguraciones aristocráticas que tienen lugar en las formaciones sociales españolas durante el s. XIX. Analizando la obra de Larra y Mesonero Romanos se observará como los elementos ideológicos del Antiguo Régimen se filtran en las nuevas perspectivas pequeñoburguesas dando lugar a esta manifestación «típica» costumbrista; no solo de forma diacrónica sino sincrónica, es decir, no como evolución teleológica del estilo y el «espíritu» españoles sino como resultado de las contradicciones entre y dentro las distintas instancias que forman el todo social. Los retratos y los artículos de costumbres serán analizados como síntomas de un programa ideológico que requiere renovarse ante la modernización creciente de las estructuras que la sostienen, pero que, sin embargo, es incapaz de escapar de las raíces oraginicistas que la forman. Se argumentará, por lo tanto, que las estructuras sociales, económicas y políticas de la España decimonónica producen esta formulación estética concreta que es el costumbrismo.Item Autonomic nervous system and cardiac neuro-signaling pathway modulation in cardiovascular disorders and Alzheimer's disease(2023-01-30) Elia, Andrea; Fossati, Silvia; Alzheimer's Center at Temple (ACT) (Temple University)The heart is a functional syncytium controlled by a delicate and sophisticated balance ensured by the tight coordination of its several cell subpopulations. Accordingly, cardiomyocytes together with the surrounding microenvironment participate in the heart tissue homeostasis. In the right atrium, the sinoatrial nodal cells regulate the cardiac impulse propagation through cardiomyocytes, thus ensuring the maintenance of the electric network in the heart tissue. Notably, the central nervous system (CNS) modulates the cardiac rhythm through the two limbs of the autonomic nervous system (ANS): the parasympathetic and sympathetic compartments. The autonomic nervous system exerts non-voluntary effects on different peripheral organs. The main neuromodulator of the Sympathetic Nervous System (SNS) is norepinephrine, while the principal neurotransmitter of the Parasympathetic Nervous System (PNS) is acetylcholine. Through these two main neurohormones, the ANS can gradually regulate cardiac, vascular, visceral, and glandular functions by turning on one of its two branches (adrenergic and/or cholinergic), which exert opposite effects on targeted organs. Besides these neuromodulators, the cardiac nervous system is ruled by specific neuropeptides (neurotrophic factors) that help to preserve innervation homeostasis through the myocardial layers (from epicardium to endocardium). Interestingly, the dysregulation of this neuro-signaling pathway may expose the cardiac tissue to severe disorders of different etiology and nature. Specifically, a maladaptive remodeling of the cardiac nervous system may culminate in a progressive loss of neurotrophins, thus leading to severe myocardial denervation, as observed in different cardiometabolic and neurodegenerative diseases (myocardial infarction, heart failure, Alzheimer’s disease). This review analyzes the current knowledge on the pathophysiological processes involved in cardiac nervous system impairment from the perspectives of both cardiac disorders and a widely diffused and devastating neurodegenerative disorder, Alzheimer’s disease, proposing a relationship between neurodegeneration, loss of neurotrophic factors, and cardiac nervous system impairment. This overview is conducive to a more comprehensive understanding of the process of cardiac neuro-signaling dysfunction, while bringing to light potential therapeutic scenarios to correct or delay the adverse cardiovascular remodeling, thus improving the cardiac prognosis and quality of life in patients with heart or neurodegenerative disorders.Item Theory Follows Photography: The Evolving Gaze of Denise Scott Brown(2023-01-30) Meninato, PabloThroughout history, architects have communicated their ideas through writing, drawing, model-making, speculation, and built work. Photography, which appeared in architecture books at the beginning of the 20th century, was mostly considered to be ancillary to the written word. A recent exhibition of photographs by Denise Scott Brown at Tyler School of Art and Architecture in Philadelphia during summer 2021 demonstrates the possibility of another creative and intellectual path for the medium. Photography simultaneously serves as a precedent and catalyst for architectural and urban thinking and theory. This article aims to examine the relationship and continuity between Scott Brown's photographs and the ideas that she conveyed in essays and books. Photography, therefore, becomes the catalyst for writings that integrate disparate topics, such as anthropology, vernaculars, history, and Pop Art, as the iconology of Las Vegas and the changing urban landscape of Philadelphia. Embodying a new creative paradigm, Scott Brown's photography anticipates theory.Item Incorporation of paclitaxel in mesenchymal stem cells using nanoengineering upregulates antioxidant response, CXCR4 expression and enhances tumor homing(2023-02-02) Prabha, Swayam; Merali, Carmen; Sehgal, Drishti; Nicolas, Emmanuelle; Bhaskar, Nitu; Flores, Magda; BHATNAGAR, SHUBHMITA; Nethi, Susheel; Barrero, Carlos; Merali, Salim; Panyam, Jayanth; Fels Cancer Institute for Personalized Medicine (Temple University); Fox Chase Cancer Center (Temple University)Engineered mesenchymal stem cells (MSCs) have been investigated extensively for gene delivery and, more recently, for targeted small molecule delivery. While preclinical studies demonstrate the potential of MSCs for targeted delivery, clinical studies suggest that tumor homing of native MSCs may be inefficient. We report here a surprising finding that loading MSCs with the anticancer drug paclitaxel (PTX) by nanoengineering results in significantly improved tumor homing compared to naïve MSCs. Loading PTX in MSCs results in increased levels of mitochondrial reactive oxygen species (ROS). In response to this oxidative stress, MSCs upregulate two important set of proteins. First were critical antioxidant proteins, most importantly nuclear factor erythroid 2-like 2 (Nrf2), the master regulator of antioxidant responses; upregulation of antioxidant proteins may explain how MSCs protect themselves from drug-induced oxidative stress. The second was CXCR4, a direct target of Nrf2 and a key mediator of tumor homing; upregulation of CXCR4 suggested a mechanism that may underlie the improved tumor homing of nanoengineered MSCs. In addition to demonstrating the potential mechanism of improved tumor targeting of nanoengineered MSCs, our studies reveal that MSCs utilize a novel mechanism of resistance against drug-induced oxidative stress and cell death, explaining how MSCs can deliver therapeutic concentrations of cytotoxic payload while maintaining their viability.Item Antimicrobial Chemotherapy for Recalcitrant Severe Human Periodontitis(2023-01-28) Rams, Thomas; Slots, JørgenThis study evaluated a combined systemic and topical anti-infective periodontal treatment of 35 adults who had experienced ongoing periodontal breakdown following conventional surgical periodontics. The prescribed anti-infective therapy, based on microbiological testing, consisted of a single course of metronidazole plus ciprofloxacin (23 patients), metronidazole plus amoxicillin/clavulanic acid (10 patients), and metronidazole plus ciprofloxacin followed by metronidazole plus amoxicillin/clavulanic acid (2 patients). In addition, the study patients received 0.1% povidone-iodine subgingival disinfection during non-surgical root debridement and daily patient administered oral irrigation with 0.1% sodium hypochlorite. At 1 and 5 years post-treatment, all study patients showed gains in clinical periodontal attachment with no further attachment loss, and significant decreases in pocket probing depth, bleeding on probing, and subgingival temperature. The greatest disease resolution occurred in patients who at baseline harbored predominantly major periodontal pathogens which post-antibiotics became non-detectable and substituted by non-periodontopathic viridans streptococci. The personalized and minimally invasive anti-infective treatment regimen described here controlled periodontitis disease activity and markedly improved the clinical and microbiological status of the refractory periodontitis patients.Item Association between reward-related functional connectivity and tri-level mood and anxiety symptoms(2023-02-02) Anderson, Zachary; Damme, Katherine S.F.; Carroll, Ann L.; Chat, Ka-Yi; Young, Katherine S.; Craske, Michelle G.; Bookheimer, Susan; Zinbarg, Richard; Nusslock, RobinDepression and anxiety are associated with abnormalities in brain regions that process rewards including the medial orbitofrontal cortex (mOFC), the ventral striatum (VS), and the amygdala. However, there are inconsistencies in these findings. This may be due to past reliance on categorical diagnoses that, while valuable, provide less precision than may be required to understand subtle neural changes associated with symptoms of depression and anxiety. In contrast, the tri-level model defines symptom dimensions that are common (General Distress) or relatively specific (Anhedonia-Apprehension, Fears) to depression and anxiety related disorders, which provide increased precision. In the current study, eligibility was assessed by quasi-orthogonal screening questionnaires measuring reward and threat sensitivity (Behavioral Activation Scale; Eysenck Personality Questionnaire-Neuroticism). These participants were assessed on tri-level symptom severity and completed the Monetary Incentive Delay task during fMRI scanning. VS-mOFC and VS-amygdala connectivity were estimated during reward anticipation and reward outcome. Heightened General Distress was associated with lower VS-mOFC connectivity during reward anticipation (b = -0.064, p = 0.021) and reward outcome (b = -0.102, p = 0.014). Heightened Anhedonia-Apprehension was associated with greater VS-amygdala connectivity during reward anticipation (b = 0.065, p = 0.004). The present work has important implications for understanding the coupling between the mOFC and vS and the amygdala and the vS during reward processing in the pathophysiology of mood and anxiety symptoms and for developing targeted behavioral, pharmacological, and neuromodulatory interventions to help manage these symptoms.Item Revitalizing Ethnographic Studies of Immigration and Crime(2023-01) Zaatut, Amarat; DiPietro, Stephanie M.Ethnographic studies of immigration and crime were prominent in the early decades of the twentieth century, yet contemporary scholarship has been dominated by quantitative approaches. In this review, we heed the call of those who have lamented the “collective amnesia” and “newness fetish” that characterize much of contemporary criminology and revisit classic ethnographies of immigration and crime, with an emphasis on the unique methodological contributions of this early work. Next, we synthesize the small but growing body of contemporary ethnographic research on immigration and crime, which includes the policing of immigrant communities in the age of “crimmigration;” the lived experiences inside contemporary deportation/detention regimes; the integration experiences of Muslims, a highly marginalized but understudied population; and immigrants’ unique vulnerabilities to and experiences of victimization, to illustrate the value of qualitative approaches for capturing the nuances of immigrants’ experiences in the new age of immigration.Item Effects of season and latitude on the diet quality of the invasive Asian shore crab Hemigrapsus sanguineus(2023-01-26) Reese, T.C.; Alder, J.; Asay, E.G.; Blakeslee, A.M.H.; Cabrera, D.; Crane, L.C.; Fletcher, L.S.; Pinkston, E.; Repetto, Michele; Smith, N.; Stancil, C.; Tepolt, C.K.; Toscano, B.J.; Griffen, B.D.Invasive species alter invaded ecosystems via direct impacts such as consumption. In turn, an invasive species’ ability to thrive in new habitats depends on its ability to exploit available resources, which may change over time and space. Diet quality and quantity are indicators of a consumer’s consumptive effects and can be strongly influenced by season and latitude. We examined the effects of season and latitude on the diet quality and quantity of the invasive Asian shore crab Hemigrapsus sanguineus throughout a non-winter sampling year at 5 different sites spanning 8° of latitude across its invaded United States range. We found that diet quality, averaged through time, largely follows an expected latitudinal cline, being higher in the center of its range and lower toward the southern and northern edges. We also found that while some sites show similar patterns of diet quality variation with season, no pattern is consistent across all latitudes. Finally, we found that crabs at sites with low diet quality during summer reproductive months did not compensate by increasing total consumption. Because the Asian shore crab is an important consumer in its invaded ecosystems, understanding how its diet quality and quantity vary with season and latitude can help us better understand how this species influences trophic interactions and community structure, how it has been able to establish across a wide ecological and environmental range, and where future range expansion is most likely to occur.Item Highlights from the Tenth International Workshop on HIV Persistence during Therapy, December 13-16, 2022, Miami, Florida-USA(2023-02-28) Archin, N.; Bar, K.J.; Burdo, Tricia; Caskey, M.; Chahroudi, A.; Farzan, M.; Ho, Y.-C.; Jones, R.B.; Kearney, Mary; Kuritzkes, D.; Margolis, D.; Martinez-Picado, J.; Okoye, A.; Salgado, M.; Stevenson, MarioThe International Workshop on HIV Persistence during Therapy provides a forum in which HIV/AIDS researchers gather to share the latest research findings related to viral reservoirs and cure. The Tenth Workshop, which was attended by over 400 delegates, extended over 4 days and comprised eight sessions covering topics from the basic science of viral persistence to therapeutic approaches to HIV cure. Furthermore, satellite sessions on the first day of the Conference featuring cure research endeavours being pursued by the Bill and Melinda Gates Foundation as well as those being coordinated under the National Institutes of Health Martin Delaney Collaboratory program, provided important updates on research advances being made in these initiatives. As with previous conferences, the International Workshop on HIV Persistence during Therapy is primarily abstract-driven with only one invited talk for each of the sessions. This format, therefore, increases the number of presentations from early-stage investigators. Furthermore, presentations by Community representatives illustrated approaches to creating cure research literacy with effective messaging for the Community. The following article offers a synopsis of the meeting sessions. Due to space constraints, some presentations may have only been briefly discussed. Nevertheless, the Workshop abstracts can be found online (https://www/sciencedirect.com/journal/journal-of-virus-eradication/vol/8/suppl/S).Item Continuum limit of parton distribution functions from the pseudo-distribution approach on the lattice(2023-04-06) Bhat, Manjunath; Chomicki, Wojciech; Cichy, Krzysztof; Constantinou, Martha; Green, Jeremy R.; Scapellato, AuroraPrecise exploration of the partonic structure of the nucleon is one of the most important aims of high-energy physics. In recent years, it has become possible to address this topic with first principle lattice QCD investigations. In this talk, we focus on the so-called pseudo-distribution approach to determine the isovector unpolarized PDFs. In particular, we employ three lattice spacings to study discretization effects and extract the distributions in the continuum limit, at a pion mass of around 370 MeV. Also, for the first time with pseudo-PDFs, we explore effects of the 2-loop matching from pseudo- to light-cone distributions.Item Nucleon electromagnetic form factors using Nf=2+1+1 twisted mass fermion ensembles at the physical mass point(2023-01-26) Koutsou, Giannis; Alexandrou, Constantia; Bacchio, Simone; Constantinou, Martha; Finkenrath, Jacob; Hadjiyiannakou, Kyriakos; Jansen, Karl; Spanoudes, GregorisWe present results for the nucleon electromagnetic form factors using Nf=2+1+1 twisted mass lattice QCD with clover improvement and with quarks with masses tuned to their physical values. Our preliminary analysis includes three ensembles at similar physical volume and varying lattice spacing allowing us to take the continuum limit at the physical point. Both connected and disconnected contributions are evaluated, allowing us to take the isovector and isoscalar contributions as well as the individual proton and neutron form factors in the flavour isospin limit. For each ensemble we assess excited state effects using several sink-source time separations in the range 0.8 fm - 1.6 fm, exponentially increasing statistics with the separation.
