Symmetric doubly periodic gravity-capillary waves with small vorticity

We construct small amplitude gravity-capillary water waves with small nonzero vorticity, in three spatial dimensions, bifurcating from uniform flows. The waves are symmetric, and periodic in both horizontal coordinates. The proof is inspired by Lortz' construction of magnetohydrostatic equilibria in reflection-symmetric toroidal domains. It relies on a representation of the vorticity as the cross

System and method for performing motion-insensitive and quiet three-dimensional magnetic resonance imaging

A method for generating motion-corrected medical images includes obtaining, via a processor, k-space data of a region of interest acquired by a magnetic resonance imaging system utilizing a 3D radial pulse sequence with ZTE acquisition including optional magnetization preparation pulses. The method also includes sampling, via the processor, the k-space data to obtain a plurality of interleaved k-s

Clandestine Communications in Cyber-Denied Environments : Numbers stations and radio in the 21st century

Both intelligence operatives and criminals have a constant need to be able to communicate clandestinely, circumventing surveillance efforts carried out by highly capable adversaries. The recent highly-publicized breaches of internet-based clandestine communications technology and targeted malware attacks, in combination with increasingly sophisticated methods for surveillance of internet traffic h

Genome-wide mRNA profiling in urinary extracellular vesicles reveals stress gene signature for diabetic kidney disease

Urinary extracellular vesicles (uEV) are a largely unexplored source of kidney-derived mRNAs with potential to serve as a liquid kidney biopsy. We assessed ∼200 uEV mRNA samples from clinical studies by genome-wide sequencing to discover mechanisms and candidate biomarkers of diabetic kidney disease (DKD) in Type 1 diabetes (T1D) with replication in Type 1 and 2 diabetes. Sequencing reproducibly s

Anledningar till att personer i Europa och USA är tveksamma till vaccination mot COVID-19

Bakgrund: WHO klassar vaccinationsmotstånd som ett av de största hoten mot folkhälsan i modern tid. COVID-19 drabbade världen med stor kraft och vaccination var en förutsättning för att kunna återfå ett fungerande samhälle. Samtidigt sågs en utbredd vaccinationstveksamhet. Sjuksköterskor möter vaccintveksamma personer och för att kunna bemöta och vägleda dem till god hälsa är det viktigt att först

Support Needs Among Older Tenants Living in Public Housing in Sweden : Perspectives of Janitors and Maintenance Staff

Neighborhood support can improve aging in place for older adults, but research on the role of public housing staff in supporting older tenants is lacking. Twenty-nine participants (janitors, n = 11; maintenance staff, n = 18) collected data about critical situations among older tenants residing in apartments in Sweden. Modifying the Critical Incident Technique (CIT) and applying a mixed-methods de

Developing an experimental-computational workflow to study the biomechanics of the human conventional aqueous outflow pathway

The aqueous humor actively interacts with the trabecular meshwork (TM), juxtacanalicular tissue (JCT), and Schlemm's canal (SC) through a dynamic fluid-structure interaction (FSI) coupling. Despite the fact that intraocular pressure (IOP) undergoes significant fluctuations, our understanding of the hyperviscoelastic biomechanical properties of the aqueous outflow tissues is limited. In this study,

Soviet Marshal Konev’s Posthumous Battle of Municipal District Prague 6

This text deals with the analysis of the removal of the monument to Soviet Marshal Ivan Konev from the Prague 6 district, an important part of the capital of the Czech Republic. The given monument was built during the Soviet occupation of Czechoslovakia in 1980 and removed in 2020. The primary reason for the removal was the dissatisfaction of the political representation of Prague 6 and the leader

Separation and Extraction of Proteins and Polysaccharides from the Seaweed Palmaria Palmata using Enzyme Digestion

Inom matindustrin och djurfoderindustrin finns det stor potential för användning av tång som näringsrikt födoämne. Palmaria palmata (P. Palmata), eller i vardagligt tal, dulse är ett rött sjögräs med högt proteininnehåll (8-35%), som innehåller många mineraler som t.ex. jod och är rikt på fiber. Den vanligaste polysackariden i dulse är xylan. Vetenskapliga artiklar föreslår att xylan är delvis bunSeaweed an unexploited nutritional source with potential in human food and animal feed industry. Seaweed has a great potential within human food and animal feed industry. Seaweed in food is the most important utilization area of acro algae today. It can be used as direct consumption, functional foods and as additives such as carrageen, alginates and agar. Dulse is a red seaweed which has a high pr

Characterization of telomeric single-stranded 3' overhangs and t-circles in Naumovozyma castellii

Telomeres, the guardians of the chromosomes Telomeres are structures found at the end of eukaryotic chromosomes. They are composed of a repetitive DNA sequence and proteins, and their main function is to protect the chromosome ends. In human somatic cells telomeres shorten with each cell division, acting as a biological clock of cell aging. However, cancer cells are able to divide infinitely by r

Naive poison frog tadpoles use bi-modal cues to avoid insect predators but not heterospecific predatory tadpoles

For animals to survive until reproduction, it is crucial that juveniles successfully detect potential predators and respond with appropriate behavior. The recognition of cues originating from predators can be innate or learned. Cues of various modalities might be used alone or in multi-modal combinations to detect and distinguish predators but studies investigating multi-modal integration in p
