Electrostatic pair-potentials based on the Poisson equation

Electrostatic pair-potentials within molecular simulations are often based on empirical data, cancellation of derivatives or moments, or statistical distributions of image-particles. In this work we start with the fundamental Poisson equation and show that no truncated Coulomb pair-potential, unsurprisingly, can solve the Poisson equation. For any such pair-potential the Poisson equation gives two

Social assistance and mental health: evidence from longitudinal administrative data on pharmaceutical consumption

This paper adds to the small literature on the role of welfare benefits and mental health by studying the relationship between uptake of Social Assistance Benefit (SAB) and objective mental health measures. We use rich longitudinal administrative data on income, unemployment benefits and psychopharmaceutic prescriptions (antidepressants, anxiolytics, and hypnotics) for more than 140,000 Swedes in

Design of an area efficient crypto processor for 3GPP-LTE NB-IoT devices

Providing information security is crucial for the Internet of Things (IoT) devices, platforms in which the available power budget is very limited. This paper tackles this challenge and presents a cryptographic processor compliant with the security algorithms specified by the 3rd Generation Partnership Project (3GPP) Long Term Evolution (LTE) NarrowBand IoT (NB-IoT) standard. The proposed processor

Pheochromocytoma – An ECG diagnosis?

Pheochromocytoma is a rare catecholamine-secreting tumor in the adrenal medulla. In some cases, the first symptoms are cardiovascular. We report on two patients with pheochromocytoma, who both presented with bidirectional ventricular tachycardia (BDVT). We elaborate on the mechanisms of BDVT in the setting of pheochromocytoma.

Incisional negative pressure wound therapy for the prevention of surgical site infection after open lower limb revascularization – Rationale and design of a multi-center randomized controlled trial

Introduction: Lower limb revascularization with inguinal incisions is a common vascular surgical procedure. Due to risk of injury to lymphatic vessels and a diverse bacterial flora in the groin, surgical site infections (SSI) represent a common and sometimes life-threatening complication. While transverse incisions in endovascular aneurysm repair has a low SSI rate, vertical incisions in thrombend

Computational simulation data using the Lattice Boltzmann method to generate correlations for gas diffusion layer parameters

Analyzing the fluid behavior in complex porous media like gas diffusion layers (GDLs) in polymer electrolyte fuel cells (PEFCs) can be accurately done using the lattice Boltzmann method (LBM). This article shows the data obtained from a study in which diffusion parameters such as porosity, gas phase tortuosity and diffusibility are computed considering simulated porous media [1]. The data were com

On the Taut String Interpretation and Other Properties of the Rudin–Osher–Fatemi Model in One Dimension

We study the one-dimensional version of the Rudin–Osher–Fatemi (ROF) denoising model and some related TV-minimization problems. A new proof of the equivalence between the ROF model and the so-called taut string algorithm is presented, and a fundamental estimate on the denoised signal in terms of the corrupted signal is derived. Based on duality and the projection theorem in Hilbert space, the proo

Impact of Multiple Myocardial Scars Detected by CMR in Patients Following STEMI

Objectives: This study investigated the incidence and long-term prognostic importance of multiple myocardial scars in cardiac magnetic resonance (CMR) in a large contemporary cohort of patients with ST-segment elevation myocardial infarction (STEMI). Background: Patients presenting with STEMI may have multiple infarctions/scars caused by multiple culprit lesions, previous myocardial infarction (MI

The prediction of colorectal cancer using anthropometric measures : A Swedish population-based cohort study with 22 years of follow-up

Background: Obesity is a risk factor for colorectal cancer (CRC). Objective: The objective of this article is to investigate whether anthropometric measures reflecting visceral obesity are better predictors of CRC than body mass index (BMI). Methods: Data were analysed from the Malmö Diet and Cancer study in Sweden, comprising 16,669 women and 10,805 men (median age 56.6 and 59.1 years) followed f

Vertical temperature gradients in apartments with hydronic radiator heating

A vertical temperature stratification normally exists in rooms during the heat-ing season in cold climates. An expression of the gradient in apartments heated by hydronic radiator heating systems with exhaust ventilation has ear-lier been developed assuming a dependency of the outdoor temperature.

Health-related quality of life after apalutamide treatment in patients with metastatic castration-sensitive prostate cancer (TITAN) : a randomised, placebo-controlled, phase 3 study

Background: In the phase 3 TITAN study, the addition of apalutamide to androgen deprivation therapy (ADT) significantly improved the primary endpoints of overall survival and radiographic progression-free survival in patients with metastatic castration-sensitive prostate cancer. We aimed to assess health-related quality of life (HRQOL) in TITAN, including pain and fatigue. Methods: In this randomi

A Target-Detecting Visual Neuron in the Dragonfly Locks on to Selectively Attended Targets

The visual world projects a complex and rapidly changing image onto the retina of many animal species. This presents computational challenges for those animals reliant on visual processing to provide an accurate representation of the world. One such challenge is parsing a visual scene for the most salient targets, such as the selection of prey amid a swarm. The ability to selectively prioritize pr

A global synthesis reveals biodiversity-mediated benefits for crop production

Human land use threatens global biodiversity and compromises multiple ecosystem functions critical to food production. Whether crop yield-related ecosystem services can be maintained by a few dominant species or rely on high richness remains unclear. Using a global database from 89 studies (with 1475 locations), we partition the relative importance of species richness, abundance, and dominance for

A system of conservation laws with discontinuous flux modelling flotation with sedimentation

The continuous unit operation of flotation is extensively used in mineral processing, wastewater treatment and other applications for selectively separating hydrophobic particles (or droplets) from hydrophilic ones, where both are suspended in a viscous fluid. Within a flotation column, the hydrophobic particles are attached to gas bubbles that are injected and float as aggregates forming a foam o

Internet Searches, Household Sentiment and Credit Spreads

We use Google internet search volumes to measure households’ pessimism about overall market-wide credit health in the economy, and show that this “household default sentiment” is positively correlated with the credit default swap (CDS) spread level in the market. However, while household default sentiment might drive the cost of credit to some degree, either directly or indirectly through its effe

Cavity Field Control for Linear Particle Accelerators

High-energy linear particle accelerators enable exploration of the microscopic structure of pharmaceuticals, solar cells, fuel cells, high-temperature superconductors, and the universe itself. These accelerators accelerate charged particles using oscillating magnetic fields that are confined in metal cavities. The amplitudes and phases of the electromagnetic fields need to be accurately controlled
