Based on stochastic differential equations (SDEs), we analyse the overall performance of heterogeneous power systems network, subject to spatially distributed and correlated noises with random initial conditions. We determine bounds on the H2 norm of the heterogeneous system based on a closedform of the norm of the homogeneous power system. Then, we formulate possible scenarios for performance opt

This study deals with the desalination plant at the Eastern Mediterranean University (Cyprus) and its environmental impact. The reverse osmosis plant produces normally 42m3/hr potable water from 120m3/hr feed. The feed concentration reaches up to 36,000ppm TDS, while an approximate amount of 73.8m3/hr is led out from a pipe of 10inches diameter with a concentration of about 56,000ppm and the perme

Resective surgery for exocrine pancreatic cancer can currently be performed with little or no hospital mortality. The operation is most often performed as a Whipple resection, but several modifications (e.g., subtotal pancreatectomy) have been advocated. The pylorus-preserving modification has gained in popularity, although its ability to remove all lymph nodes has been questioned. Total pancreate

Just nu finns det en möjlighet för politikerna att lägga om stadsplaneringen så att det blir möjligt att nå FN:s hållbarhetsmål. Det skriver åtta forskare som arbetar med miljö- och hälsofrågor.

It remains a big challenge to elongate one-dimensional (1D) semiconductor nanowires (NWs), which can be attractive platforms for miniaturizing and/or integrating macroscopic devices, into centimeter-scale length. Herein, we report the innovative preparation of single-crystalline III-nitride NWs, with unprecedented length above 2 cm and the aspect ratio above 6000, by graphically epitaxial lifting-

Under hypoxic conditions, some organisms use an electron transport chain consisting of only complex I and II (CII) to generate the proton gradient essential for ATP production. In these cases, CII functions as a fumarate reductase that accepts electrons from a low electron potential quinol, rhodoquinol (RQ). To clarify the origins of RQ-mediated fumarate reduction in eukaryotes, we investigated th

Background Many microbial eukaryotes have evolved anaerobic alternatives to mitochondria known as mitochondrion-related organelles (MROs). Yet, only a few of these have been experimentally investigated. Here we report an RNA-seq-based reconstruction of the MRO proteome of Pygsuia biforma, an anaerobic representative of an unexplored deep-branching eukaryotic lineage. Results Pygsuia's MRO has a co

Partially premixed combustion (PPC) is one of the advanced combustion concepts that is being actively investigated. A joint experimental and numerical investigations were conducted to explore the effects of octane number and injection timing on the autoignition behaviour with primary reference fuel (PRF) and gasoline fuels under PPC mode in a light-duty DICI engine. In this study, the start of inj

The research community recently proposed a low-temperature combustion (LTC) concept that can simultaneously reduce Nitrogen Oxides (NOx) and soot emissions while maintaining high engine efficiency. Given that diesel fuel is prone to preignition with early injection, gasoline-like fuel with high octane number is utilised to provide sufficient ignition delay and extend the load range. Understanding

Background and aims: Children with extremely low-birth weight (ELBW) have a high risk for cognitive, motor, and attention impairments and learning disabilities. Longitudinal follow-up studies to a later age are needed in order to increase understanding of the changes in neurodevelopmental trajectories in targeting timely intervention. The aims of this study were to investigate cognitive and motor

To evaluate the effect of antibiotic drugs, it is important that the cells that are killed can be sorted from the cells that are resistant to the antibiotics. Here we report a simple label-free method for the continuous separation of viable/non-viable cells using Electrokinetic Deterministic Lateral Displacement. In general, this opens up for continuous sorting of a population of cells that is hom

The precise separation of nanoscale particles has proven challenging due to diffusion and the need to use nanoscale devices. We show the separation of particles in the 100 nm size range in Deterministic Lateral Displacement (DLD) devices with feature sizes in the 10 µm size range. We achieve this using Dielectrophoretic (DEP) forces, generated between the metal coated posts that act as active elec

Ett systematiskt arbetsmiljöarbete med fokus på alla åldrar bör fokusera på människors förmåga och vilja att arbeta, exempelvis genom en modell med fyra olika sfärer som relaterar till olika sätt att definiera ålder.Den första sfären handlar om hälsoeffekter och relaterar till den biologiska åldern. De andra sfärerna rör privatekonomi, stöd och gemenskap samt arbetstagarnas möjligheter att utföra

The adsorption of thiophene and 2,2′-bithiophene on Ag(111) was studied using temperature programmed desorption and near-edge X-ray-absorption fine-structure (NEXAFS). The assignment of the NEXAFS resonances is supported by Xα scattered-wave calculations. For thiophene we identify a compressed and a relaxed monolayer species. Whereas the molecules in the latter state are adsorbed parallel to the s
