Existence results and Ulam-Hyers stability for a sequential deformable fractional initial value problem

Abstract In this study, we establish existence and Ulam-Hyers results for nonlinear sequential fractional differential equations involving the deformable derivative. We employ the Banach contraction principle and Krasnoselskii’s theorem to ...

Analyzing the Transparency and the Efficiency of Innovative Transparent Electrodes for Space Solar Cell Applications

In this work a study about the behavior of nanomaterial-based innovative transparent electrodes is presented, with a special focus on graphene, for space photovoltaic applications, in particular their transparency and the efficiency of the ...

Mass variation observing system by high low inter-satellite links (MOBILE) – a new concept for sustained observation of mass transport from space

As changes in gravity are directly related to mass variability, satellite missions observing the Earth’s time varying gravity field are a unique tool for observing mass transport processes in the Earth system, such as the water cycle, rapid...

SOQCS: A Stochastic Optical Quantum Circuit Simulator

Stochastic Optical Quantum Circuit Simulator (SOQCS) is a C++ and Python library which offers a framework to define, simulate and study quantum linear optical circuits in presence of various imperfections typically encountered in experiment...

Near-Integrability of Low-Dimensional Periodic Klein-Gordon Lattices

The low-dimensional periodic Klein-Gordon lattices are studied for integrability. We prove that the periodic lattice with two particles and certain nonlinear potential is nonintegrable. However, in the cases of up to six particles, we prove...

Fractional exhaled nitric oxide as a potential biomarker for radiation pneumonitis in patients with non-small cell lung cancer: A pilot study

Introduction: The aim of the study was to investigate repetitive fractional exhaled nitric oxide (FeNO) measurements during high-dose radiation therapy (HDRT) and to evaluate the use of FeNO to predict symptomatic radiation pneumonitis (RP)...

Sustainable COVID-19 Mitigation: Wuhan Lockdowns, Health Inequities, and Patient Evacuation

The world is urgently looking for ways to flatten the coronavirus disease 2019 (COVID-19) curve, and many governments have resorted to implementing strict lockdowns, as researchers show the effectiveness of China’s approaches in containing ...

Simulators with Haptic Feedback in Neurosurgery: Are We Reaching the “Aviator” Type of Training? Narrative Review and Future Perspectives

Over the last decade, the quality of neurosurgical procedures dramatically improved, also thanks to the development and increased accessibility of several technological recourses (e.g., imaging, neuronavigation, neurophysiology, microscopy)...

Safety Perceptions among Ship-to-Shore (STS) Crane Operators at PT Terminal Teluk Lamong

Introduction: Ship-to-shore (STS) crane operators strive for efficiency in their work, but they must take a hard look at their high-risk jobs. It is necessary to learn how to improve occupational safety and health. This study aims to invest...

Early disc degeneration in radiotherapy-treated childhood brain tumor survivors

Abstract Background Childhood brain tumor (BT) survivors have an increased risk of treatment-related late effects, which can reduce health-related quality of life and increase morbidity. This study aimed to investigate lumbar disc degenerat...

Memory and Synaptic Devices Based on Emerging 2D Ferroelectricity

Abstract Memory devices are an essential part of modern electronics. Efforts to move beyond the traditional “read” and “write” of digital information in volatile and non‐volatile memory devices are leading to the rapid growth of neuromorphi...

Medical Informatics Is Interdisciplinary avant la Lettre

OBJECTIVE: To discuss the elements of interdisciplinary research and to analyze its contribution to (bio)medical informatics. METHOD: Commenting on 'Informatics and Medicine - From Molecules to Populations' from K. A. Kuhn et al. in this is...

Dichloroacetate as a metabolic modulator of heart mitochondrial proteome under conditions of reduced oxygen utilization

Abstract Myocardial compensatory mechanisms stimulated by reduced oxygen utilization caused by streptozotocin-induced diabetes mellitus (DM) and treated with dichloroacetate (DCA) are presumably associated with the regulation of mitochondri...

Wrist movements induce torque and lever force in the scaphoid: an ex vivo study

Abstract Purpose We hypothesised that intercarpal K-wire fixation of adjacent carpal bones would reduce torque and lever force within a fractured scaphoid bone. Methods In eight cadaver wrists, a scaphoid osteotomy was stabilised using a lo...

Dopamine transporter binding in symptomatic controls and healthy volunteers: Considerations for neuroimaging trials

Objective: To evaluate possible differences between brain dopamine transporter (DAT) binding in a group of symptomatic parkinsonism patients without dopaminergic degeneration and healthy individuals. Background: Dopaminergic neuroimaging st...

Brain perfusion imaging in neonates

Abnormal variations of the neonatal brain perfusion can result in long-term neurodevelopmental consequences and cerebral perfusion imaging can play an important role in diagnostic and therapeutic decision-making. To identify at-risk situati...

The Need for a Philosophy of Medical Informatics

In the beginning of the development of our profession he had a chair in Biophysics and Biomathematics at the University of Paris, where I visited him for the first time in 1967 during a WHO scholarship [1], and later at the university in Mo...

Structural relationships within medical informatics

Medical informatics is the application of information science and information technology to the theoretical and practical problems of biomedical research, clinical practice, and medical education. Although it is broadly interdisciplinary, i...
