Optimizing Extreme Learning Machine for Drought Forecasting : Water Cycle vs. Bacterial Foraging

Machine learning (ML) methods have shown noteworthy skill in recognizing environmental patterns. However, presence of weather noise associated with the chaotic characteristics of water cycle components restricts the capability of standalone ML models in the modeling of extreme climate events such as droughts. To tackle the problem, this article suggests two novel hybrid ML models based on combinat

The Brexit battle on Facebook: assessing echo chambers and polarisation

Does online campaigning foster ‘echo chambers’ and exacerbate the polarisation of society? On Facebook, Leave and Remain supporters behaved very differently. Pro-Remain users commented mainly on like-minded Facebook pages. By avoiding confrontation with their political opponents, Remainers showed behaviour characteristic of an ‘echo chamber’. In contrast, Leavers spread their messages on pages spa

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

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,

Clonal origin and development of high hyperdiploidy in childhood acute lymphoblastic leukaemia

High hyperdiploid acute lymphoblastic leukemia (HeH ALL), one of the most common childhood malignancies, is driven by nonrandom aneuploidy (abnormal chromosome numbers) mainly comprising chromosomal gains. In this study, we investigate how aneuploidy in HeH ALL arises. Single cell whole genome sequencing of 2847 cells from nine primary cases and one normal bone marrow reveals that HeH ALL generall

SubKluster: Novel method to bin scaffolds from cereal genomes into subgenomes using substring frequency analysis

The genome of the Belinda variety of the hexaploid oat (Avena sativa) has recently been sequenced and assembled. This project aims to improve the assembly by clustering the thousands of scaffolds into their three ancestral subgenomes using Principle Component Analysis (PCA) of kmer and repeat-element frequencies. The method was developed using a chromosome level assembly of hexaploid Wheat (Tritiu

Towards optimization of anomaly detection in DevOps

Context: DevOps has recently become a mainstream solution for bridging the gaps between development (Dev) and operations (Ops) enabling cross-functional collaboration. The DevOps concept of continuous monitoring may bring a lot of benefits to development teams such as early detection of run-time errors and various performance anomalies. Objective: We aim to explore deep learning (DL) solutions for

Exposure to transportation noise and risk for cardiovascular disease in a nationwide cohort study from Denmark

BACKGROUND: Transportation noise increases the risk of ischemic heart disease (IHD), but few studies have investigated subtypes of IHD, such as myocardial infarction (MI), angina pectoris, or heart failure. We aimed to study whether exposure to road, railway and aircraft noise increased risk for ischemic heart disease (IHD), IHD subtypes, and heart failure in the entire adult Danish population, in

Parental help-seeking behaviour for, and care of, a sick or injured child during the COVID-19 pandemic: a European online survey

BackgroundGlobally, the COVID-19 pandemic had a huge impact on patients and healthcare systems. A decline in paediatric visits to healthcare settings was observed, which might have been due to lower incidence of injury and infectious illness, changes in healthcare services and parental concern. The aim of our study was to examine parental experiences of help-seeking for, and care of, a sick or inj

Access to justice and social rights for victims of trafficking and labour exploitation in Sweden

This chapter delves into the challenges encountered by victims of human trafficking and other forms of labour exploitation in Sweden as they struggle to access social rights and justice. By drawing from theories of victimisation as an interactional process, the study examines the role of professionals such as government agents, social services, unions, and NGOs as facilitators in assisting victimsThis chapter delves into the challenges encountered by victims of human trafficking and other forms of labour exploitation in Sweden as they struggle to access social rights and justice.
