Optimization and comparison of two methods for spike train estimation in an unfused tetanic contraction of low threshold motor units

Background: Recent findings have shown that imaging voluntarily activated motor units (MUs) by decomposing ultrasound-based displacement images provides estimates of unfused tetanic signals evoked by spinal motoneurons’ neural discharges (spikes). Two methods have been suggested to estimate its spike trains: band-pass filter (BPM) and Haar wavelet transform (HWM). However, the methods’ optimal par

How socio-technical regimes affect low-carbon innovation : Global pressures inhibiting industrial heat pumps in the Netherlands

This paper shows that the socio-technical barriers that sustainable innovations face, may stem from global regimes. Existing transitions approaches like the Technological Innovation System (TIS), overlook the impact of global regimes on radical innovation. Building on institutional theory, we therefore develop a theoretical framework that captures TIS-regime interaction, allowing us to analyze the

The advent of thermoplasmonic membrane distillation

Freshwater scarcity is a vital societal challenge related to climate change, population pressure, and agricultural and industrial demands. Therefore, sustainable desalination/purification of salty/contaminated water for human uses is particularly relevant. Membrane distillation is an emerging hybrid thermal-membrane technology with the potential to overcome the drawbacks of conventional desalinati

Dimensionally controlled graphene-based surfaces for photothermal membrane crystallization

Membrane-based photothermal crystallization - a pioneering technology for mining valuable minerals from seawater and brines - exploits self-heating nanostructured interfaces to boost water evaporation, so achieving a controlled supersaturation environment that promotes the nucleation and growth of salts. This work explores, for the first time, the use of two-dimensional graphene thin films (2D-G)

Lithium recovery through WS2 nanofillers-promoted solar photothermal membrane crystallization of LiCl

The recovery of raw materials represents one of the greatest challenges for a circular economy. Especially, the increased demand for lithium in the last years for its critical role in Li-ion batteries implies the need for green technology for Li recovery able to address market requests. Here, we devise and implement a new technology exploiting excitons-based light-to-heat conversion promoted by WS

The HD 93963 A transiting system: A 1.04 d super-Earth and a 3.65 d sub-Neptune discovered by TESS and CHEOPS

We present the discovery of two small planets transiting HD 93963A (TOI-1797), a GOV star (M* = 1.109 ± 0.043M⊙, R* = 1.043 ± 0.009 R⊙) in a visual binary system. We combined TESS and CHEOPS space-borne photometry with MuSCAT 2 ground-based photometry, ‘Alopeke and PHARO high-resolution imaging, TRES and FIES reconnaissance spectroscopy, and SOPHIE radial velocity measurements. We validated and

Monobutyrin and monovalerin improve gut-blood-brain biomarkers and alter gut microbiota composition in high-fat fed apolipoprotein-E-knockout rats

Monobutyrin (MB) and monovalerin (MV), glycerol esters of short-chain fatty acids (SCFAs), have been shown to positively influence lipid profile and biomarkers in the gut and brain. This study examined whether MB and MV in high-fat diets, affected microbiota composition and gut–blood–brain markers in apolipoprotein E deficient (ApoE-/-) rats, a model for studies of lipid-associated disorders,

Control-Theoretical Perspective in Feedback-Based Systems Testing

Self-Adaptive Systems (SAS) and Cyber-Physical Systems (CPS) have received significant attention in recent computer engineering research. This is due to their ability to improve the level of autonomy of engineering artefacts. In both cases, this autonomy increase is achieved through feedback. Feedback is the iteration of sens- ing and actuation to respectively acquire knowledge about the current s

Infection Rate of SARS-CoV-2 in Asymptomatic Healthcare Workers, Sweden, June 2022

Given the recent surge in SARS-CoV-2 Omicron infections, we performed a quantitative PCR screening survey during June 28-29, 2022, in Stockholm, Sweden, to investigate SARS-CoV-2 point prevalence in a group with high exposure risk. Results showed SARS-CoV-2 infection in 2.3% of healthcare workers who were asymptomatic at time of sampling.

Oxytocin in Huntington's disease and the spectrum of amyotrophic lateral sclerosis-frontotemporal dementia

Neurodegenerative disorders (NDDs) such as Huntington's disease (HD) and the spectrum of amyotrophic lateral sclerosis (ALS) and frontotemporal dementia (FTD) are characterized by progressive loss of selectively vulnerable populations of neurons. Although often associated with motor impairments, these NDDs share several commonalities in early symptoms and signs that extend beyond motor dysfunction

Goals of Care Conversations Documented by an Embedded Emergency Department-Palliative Care Team during COVID

Background: There has been growing interest around integrating palliative care (PC) into emergency department (ED) practice but concern about feasibility and impact. In 2020, as the COVID pandemic was escalating, our hospital's ED and PC leadership created a new service of PC clinicians embedded in the ED. Objectives: To describe the clinical work of the embedded ED-PC team, in particular what was

Effects of Proteases from Pineapple and Papaya on Protein Digestive Capacity and Gut Microbiota in Healthy C57BL/6 Mice and Dose-Manner Response on Mucosal Permeability in Human Reconstructed Intestinal 3D Tissue Model

Cysteine proteases obtained from the stem of pineapple or papaya latex, bromelain and papain, respectively, exhibit a broad spectrum of beneficial effects on human health. However, their effects on gut microbiota composition or dose-manner effects on the intestinal integrity of healthy tissue have not been evaluated. In this study, C57BL/6 young, healthy mice were fed bromelain or papain in a dose

Civil-Military Collaboration to Facilitate Rapid Deployment of a Mobile Laboratory in Early Response to COVID-19 : A High-Readiness Exercise

Rapid and adaptable diagnostic capabilities are of great importance in the face of emerging infectious diseases. In an outbreak, timely establishment of diagnostic routines is crucial to identifying cases and preventing the spread of the disease, especially when faced with high-consequence pathogens. In this article, we describe a multiagency exercise including the rapid deployment and diagnostic

The Origins of the Swedish Wage Bargaining Model

This paper revisits the development of the canonical Swedish wage bargaining model, from the 1930s to the 1950s. The question at the core of the debate is: how did Sweden achieve “good” wage bargaining institutions -- good, in the sense of facilitating investment, employment, and controlled inflation? The conventional account focuses on the actions of employers and trade unions in export industry,This paper revisits the development of the canonical Swedish wage bargaining model, from the 1930s to the 1950s.

Increasing terrestrial ecosystem carbon release in response to autumn cooling and warming

Part of the Northern Hemisphere has experienced widespread autumn cooling during the most recent decades despite overall warming, but how this contrasting temperature change has influenced the ecosystem carbon exchange remains unclear. Here, we show that autumn cooling has occurred over about half of the area north of 25° N since 2004, producing a weak cooling trend over the period 2004–2018. Mult
