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

Big Five of Mindfulness and Personality: Cross-Cultural Network Analysis

ObjectivesResearch on personality seeks to understand what makes people similar or distinct from another. However, there is still a limited understanding of processes that underpin an individual’s personality, such as interactions with other psychological dispositions such as trait mindfulness. Elucidating the unique relationships between mindfulness and personality traits with network analysis ca

Persistent pain and its predictors after starting anti-tumour necrosis factor therapy in psoriatic arthritis : what is the role of inflammation control?

Objective: While considerable focus has been placed on pain due to inflammation in psoriatic arthritis (PsA), less is reported on pain despite inflammation control. Here, we aimed to investigate the occurrence/predictors of persistent pain, including non-inflammatory components, after starting anti-tumour necrosis factor (anti-TNF) therapy. Method: Bionaïve PsA patients starting a first anti-TNF t

Interplay between Brownian and hydrodynamic tracer diffusion in suspensions of swimming microorganisms

The general problem of tracer diffusion in non-equilibrium baths is important in a wide range of systems, from the cellular level to geographical length scales. In this paper, we revisit the archetypical example of such a system: A collection of small passive particles immersed in a dilute suspension of non-interacting dipolar microswimmers, representing bacteria or algae. In particular, we consid

Macro- and microscopic changes in veins with short-term central venous catheters : an observational autopsy study

BACKGROUND: Centrally inserted central catheters (CICCs) are indispensable in modern healthcare, but unfortunately, come with complications. Catheter-related thrombosis is a well-known complication reported to occur in 5-30% of patients with CICC. There is a paucity of studies that report the incidence of catheter-related thrombosis after the introduction of real-time ultrasound insertion guidance

Unique contributions of anxiety, stress and depression to immunity: A cross-cultural investigation

While immunity and psychological distress are strongly associated, studies seldom consider how different types of distress relate to immune functioning. The literature tends to emphasis the impact of stress on immunity. The present cross-sectional study estimated the unique contributions of depression, anxiety, and stress on immune function in culturally diverse samples of adults from Italy, New Z

Carbon dioxide and methane fluxes from mounds of African fungus-growing termites

Termites play an essential role in decomposing dead plant material in tropical ecosystems and are thus major sources of gaseous C emissions in many environments. In African savannas, fungus-growing termites are among the ecologically most influential termite species. We studied the gas exchange from mounds of two closely related fungus-growing species (Macrotermes subhyalinus and M. michaelseni, r

Non-symmetric responses of leaf onset date to natural warming and cooling in northern ecosystems

The northern hemisphere has experienced regional cooling, especially during the global warming hiatus (1998-2012) due to ocean energy redistribution. However, the lack of studies about the natural cooling effects hampers our understanding of vegetation responses to climate change. Using 15,125 ground phenological time series at 3,620 sites since the 1950s and 31-year satellite greenness observatio

Structure of Responsive Microgels down to Ultralow Cross-Linkings

Although microgels have been widely used as model systems for soft colloids, their properties are still far from being completely understood. This stems from their heterogeneous structure strongly differing from that of an idealized polymeric network. Indeed, microgels synthesized by conventional precipitation polymerization exhibit not only a fuzzy structure with respect to the difference of reac

Effects and Limitations of a Unique, Nationwide, Self-Exclusion Service for Gambling Disorder and Its Self-Perceived Effects and Harms in Gamblers : Protocol for a Qualitative Interview Study

Background: Voluntary self-exclusion from gambling is a common but underdeveloped harm reduction tool in the management of gambling problems or gambling disorders. Large-scale, multi-operator, and operator-independent self-exclusion services are needed. A recent nationwide multi-operator self-exclusion service in Sweden (Spelpaus), involving both land- and web-based gambling sites, is promising, b

Effect of pore density and filling ratio of metal foam on melting performance in a heat storage tank

Thermal energy storage through solid–liquid phase change is an efficient method for mitigating solar energy intermittency by providing continuous energy supply for the end-users. However, the low thermal conductivity of phase change material, which serves as the heat transfer medium in the thermal energy storage systems, severely undermines the heat charging/discharging rates. Metal foam can signi

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

Health systems resilience in fragile and conflict-affected settings : a systematic scoping review

BACKGROUND: Health systems resilience (HSR) research is a rapidly expanding field, in which key concepts are discussed and theoretical frameworks are emerging with vibrant debate. Fragile and conflict-affected settings (FCAS) are contexts exposed to compounding stressors, for which resilience is an important characteristic. However, only limited evidence has been generated in such settings. We con

Palaeoenvironmental changes in eastern Crimea over the last 7600 years inferred from a multi-proxy study of a sediment archive from Lake Chokrak

The study presents a multi-proxy archive from hypersaline coastal Lake Chokrak in eastern Crimea, a steppe region which is particularly susceptible to moisture fluctuations. XRF, organic carbon and nitrogen, and palynological analyses are used to reconstruct the evolution of the lake and landscape development around it and to provide information about the driving forces behind those changes, such

Book review: "Authoritarian Police in Democracy: Contested Security in Latin America. by Yanilda María González. Cambridge University Press"

Yanilda González has written a landmark study addressing a highly contentious issue of our time: the persistence of authoritarian policing practices in numerous countries, despite their transition to democracy. The central question explored in the book is how to reform the police bureaucracy, an institution tasked with ensuring security but often becoming the primary source of insecurity for citiz

Acyl ghrelin increases cardiac output while preserving right ventricular-pulmonary arterial coupling in heart failure

Aim: Acyl ghrelin increases cardiac output (CO) in heart failure with reduced ejection fraction (HFrEF). This could impair the right ventricular-pulmonary arterial coupling (RVPAC), both through an increased venous return and right ventricular afterload. We aim to investigate if acyl ghrelin increases CO with or without worsening the right-sided haemodynamics in HFrEF assessed by RVPAC. Methods an
