Precise localization of corneal reflections in eye images using deep learning trained on synthetic data

We present a deep learning method for accurately localizing the center of a single corneal reflection (CR) in an eye image. Unlike previous approaches, we use a convolutional neural network (CNN) that was trained solely using synthetic data. Using only synthetic data has the benefit of completely sidestepping the time-consuming process of manual annotation that is required for supervised training

Comparison of optimizers for model predictive thermal control of buildings

Considering recent developments in the energy sector, further reduction of electricity cost and flattening of the electric power demand curve are needed. We have focused on an autonomous electric heater control system that can easily be implemented in existing buildings without strict comfort requirements. Examples are winter heating of warehouses and vacation homes, and heat drying of buildings u

Prognostic utility and characterization of left ventricular hypertrophy using global thickness

Cardiovascular magnetic resonance (CMR) can accurately measure left ventricular (LV) mass, and several measures related to LV wall thickness exist. We hypothesized that prognosis can be used to select an optimal measure of wall thickness for characterizing LV hypertrophy. Subjects having undergone CMR were studied (cardiac patients, n = 2543; healthy volunteers, n = 100). A new measure, global wal

Age bias in artificial intelligence (AI): a visual properties analysis of AI images of older versus younger people

Concerns about age-related biases in Artificial Intelligence (AI)’s design, development, and data generation raise alarms for potential social inequalities. AI art-generators like MidJourney, known for creating distinctive and artistic images, have gained attention recently. However, the critical examination of their potential biases remains limited. Our study aims to investigate age-related bias

Older people with dementia running a pop-up restaurant: how to use reality shows to reduce the stigma of dementia

The present study focused on a Chinese reality show, Forget Me Not Café, which brought together five older people (aged 65 and older) living with dementia to run a pop-up restaurant and intended to reduce the stigma of dementia. The study aims to explore how the reality-show participants describe dementia in older people and how their views relate to the macrosocial context of dementia and older p

Ultrasound-guided subclavian vein catheterisation with a needle guide (ELUSIVE) : protocol for a randomised controlled study

INTRODUCTION: Central venous catheters are indispensable in modern healthcare. Unfortunately, they are accompanied by minor as well as major complications, leading to increased morbidity, mortality and costs. Immediate insertion-related complications (mechanical complications) have decreased due to the implementation of real-time ultrasound guidance, but they still occur and additional efforts to

Platelet transfusions in adult thrombocytopenic ICU patients : Protocol for a sub-study of the PLOT-ICU cohort

INTRODUCTION: Platelet transfusions are frequently used in intensive care unit (ICU) patients, but contemporary epidemiological data are sparse. We aim to present contemporary international data on the use of platelet transfusions in adult ICU patients with thrombocytopenia.METHODS: This is a protocol and statistical analysis plan for a post hoc sub-study of 504 thrombocytopenic patients from the

A spontaneous dissociative episode during an EEG experiment

A depersonalization episode occurred unexpectedly during an electroencephalogram (EEG) recording for a study.Experience reports tracked the time course of this event and, in conjunction, with EEG data, were analyzed. Thesource activity across canonical frequency bands was analyzed across four periods ended by retrospectiveexperience reports (depersonalization was reported in the 2nd period). Delta

Entropy based approach for precipitation monitoring network in Bihar, India

Study region: Bihar State, located in India's eastern region, displays significant spatial and temporal variation in rainfall during the Indian Summer Monsoon period with subsequent flooding problems. Study focus: Recent severe flooding problems highlight the need for improved spatial precipitation monitoring to enable effective flood management and reduce water-related disasters. To address this

Block-scale use of bioretention cells to restore the urban water balance : A case study in Tehran metropolis

Study region: A densely populated urban area located in the 13th municipality of Tehran metropolis, Iran. Study focus: Bioretention cell is one of the low-impact development methods that aims to restore the hydrological cycle in city areas before urban development. However, the bioretention cell's hydrological performance can vary in urban environments. As a result, this research investigated the

Impact of the gut microbiome on immunological responses to COVID-19 vaccination in healthy controls and people living with HIV

Although mRNA SARS-CoV-2 vaccines are generally safe and effective, in certain immunocompromised individuals they can elicit poor immunogenic responses. Among these individuals, people living with HIV (PLWH) have poor immunogenicity to several oral and parenteral vaccines. As the gut microbiome is known to affect vaccine immunogenicity, we investigated whether baseline gut microbiota predicts immu

Beyond ray optics absorption of light in CsPbBr3perovskite nanowire arrays studied experimentally and with wave optics modelling

We study experimentally and with wave optics modelling the absorption of light in CsPbBr3perovskite nanowire arrays fabricated into periodic pores of an anodized aluminum oxide matrix, for nanowire diameters from 30 to 360 nm. First, we find that all the light that couples into the array can be absorbed by the nanowires at sufficient nanowire length. This behavior is in strong contrast to the expe

Cognitive Grammar

This entry offers a short description of the fundamental assumptions of grammar within the broad framework of Cognitive Linguistics. It presents the principles of usage-based cognitive grammar (CG), classic works in the framework, and more recent treatments of grammatical structure and content in the form of examples of grammatical notions. Central to the CG approach is the meaningful functioning

Accessible and reliable neurometric testing in humans using a smartphone platform

Tests of human brain circuit function typically require fixed equipment in lab environments. We have developed a smartphone-based platform for neurometric testing. This platform, which uses AI models like computer vision, is optimized for at-home use and produces reproducible, robust results on a battery of tests, including eyeblink conditioning, prepulse inhibition of acoustic startle response, a

The Dialectics of Disaster: Considerations on Hazards and Vulnerability in the Age of Climate Breakdown, with a Brief Case Study of Khuzestan

In a historical moment inundated by disasters, understanding and conceptualising thephenomenon is a matter of some importance. No framework for doing so has been more productive than that developed by Wisner and his colleagues. But their so-called ‘Progression of Vulnerability’ (pressure and release [PAR] model) framework was conceived before the onset of the climate crisis. And that crisis, as th

The public library as a political symbol : a post-political reading of the demise of the consensus-model in Swedish cultural policy

Recent use of public libraries as political symbols by the radical right in their challenge of the established consensus in Swedish cultural policy is part of an ongoing (re)politicization of the field of cultural policy. This paper frames this development as part of a post-political condition of Swedish cultural and library policy. Through an analysis of previous research, policy, and policy deba
