Applying Positional Encoding To Enhance Vision-Language Transformers, Xuehao Liu, Sarah Jane Delany, Susan Mckeever

Conference papers

Positional encoding is used in both natural language and computer vision transformers. It provides information on sequence order and relative position of input tokens (such as of words in a sentence) for higher performance. Unlike the pure language and vision transformers, vision-language transformers do not currently exploit positional encoding schemes to enrich input information. We show that capturing location information of visual features can help vision-language transformers improve their performance. We take Oscar, one of the state-of-the-art (SOTA) vision-language transformers as an example transformer for implanting positional encoding. We use image captioning as a downstream task to test performance. We …

The Uk Psychiatrists' Experience Of Rationalising Antipsychotics In Adults With Intellectual Disabilities: A Qualitative Data Analysis Of Free-Text Questionnaire Responses, Shoumitro Deb, Bharati Limbu, Tom Nancarrow, David Gerrard, Rohit Shankar

Peninsula Medical School

Background: Overprescribing of off-licence psychotropic medications, particularly antipsychotics, for challenging behaviours in people with intellectual disabilities without a psychiatric disorder is a significant public health concern. In the United Kingdom, the National Health Service England launched an initiative in 2016, ‘STopping Over-Medication of People with learning disabilities, autism or both (STOMP)’, to address this concern. STOMP is supposed to encourage psychiatrists in the United Kingdom and elsewhere to rationalise psychotropic medication use in people with intellectual disabilities. The current study aims to gather UK psychiatrists' views and experience of implementing the STOMP initiative. Methods: An online questionnaire was sent to …

Shared Responsibility: Conceptualising How A Public Health Approach May Enhance Police Response To Missing Persons, Katie Gambier-Ross, Joe Apps Dr, Sarah Wayland Dr

International Journal of Missing Persons

When a person is reported missing there are substantial costs for the individual, their family and society. This paper conceptualises the experience of missing persons episodes, through a public health approach. This then allows police, stakeholders and the community to engage in discussions about who is vulnerable to going missing by intervening in a way that addresses risk. Historically, a missing persons episode involves an absence, typically followed by police involvement in consultation with next of kin with establishing the whereabouts of the missing person being the primary focus. Yet, the risk factors of going missing relate more to the …

Comparison Of Pulsed Electroacoustic Measurements And Af-Numit3 Modeling Of Polymers Irradiated With Monoenergetic Electrons, Zachary Gibson, J. R. Dennison, Brian Beecken, Ryan Hoffmann

Journal Articles

Successful spacecraft design and charging mitigation techniques require precise and accurate knowledge of charge deposition profiles. This paper compares models of charge deposition and transport using a venerable deep dielectric charging code, AF-NUMIT3, with direct measurements of charge profiles via pulsed electroacoustic (PEA) measurements. Eight different simulations were performed for comparison to PEA experiments of samples irradiated by 50 or 80 keV monoenergetic electrons in vacuum and at room temperature. Two materials, polyether-ether ketone (PEEK) and polytetrafluoroethylene (PTFE), were chosen for their very low conductivities so that minimal charge migration would occur between irradiation and PEA measurements. PEEK was found …

Efficacy And Safety Of Cardioprotective Drugs In Chemotherapy-Induced Cardiotoxicity: An Updated Systematic Review & Network Meta-Analysis, Ali Mir, Yasra Badi, Seif Bugazia, Anas Zakarya Nourelden, Ahmed Hashem Fathallah, Khaled Mohamed Ragab, Mohammed Alsillak, Sarah Makram Elsayed, Abdulrahman Ibrahim Hagrass, Sawyer Bawek, Mohamad Kalot, Zachary L. Brumberger

Internal Medicine Articles

BACKGROUND: Cancer patients receiving chemotherapy have an increased risk of cardiovascular complications. This limits the widespread use of lifesaving therapies, often necessitating alternate lower efficacy regimens, or precluding chemotherapy entirely. Prior studies have suggested that using common cardioprotective agents may attenuate chemotherapy-induced cardiotoxicity. However, small sample sizes and conflicting outcomes have limited the clinical significance of these results.

HYPOTHESIS: A comprehensive network meta-analysis using updated and high-quality data can provide more conclusive information to assess which drug or drug class has the most significant effect in the management of chemotherapy-induced cardiotoxicity.

METHODS: We performed a literature search for randomized controlled …
