Explaining prevalence, diversity and host specificity in a community of avian haemosporidian parasites

Many hypotheses attempt to explain parasite–host associations, but rarely are they examined together in a single community. For hosts, key traits are the proportion of infected individuals (prevalence) and the diversity of parasites infecting them. A key parasite trait is host specificity, ranging from specialists infecting one or a few closely related species to generalists infecting many species

Evaluation of integration of sustainable development in higher education in Sweden

Purpose: Since 2006, higher education institutions (HEIs) in Sweden, should according to the Higher Education Act, promote sustainable development (SD). In 2016, the Swedish Government asked the Swedish higher education authority to evaluate how this study is proceeding. The authority chose to focus on education. This paper aims to produce a report on this evaluation. Design/methodology/approach:

A virtual reality study of behavioral sequences in residential fires

Decision-making in residential fires can be difficult to study in an experimental setup. Virtual reality could be a way to expose participants to a residential fire scenario and collect data on their behavior. However, the validity of the data obtained needs to be assessed. To explore that, the data collected in two virtual reality residential fire scenarios in form of sequences of behavior was co

Spread of pathological tau proteins through communicating neurons in human Alzheimer's disease

Tau is a hallmark pathology of Alzheimer's disease, and animal models have suggested that tau spreads from cell to cell through neuronal connections, facilitated by β-amyloid (Aβ). We test this hypothesis in humans using an epidemic spreading model (ESM) to simulate tau spread, and compare these simulations to observed patterns measured using tau-PET in 312 individuals along Alzheimer's disease co

Audomni : Super-Scale Sensory Supplementation to Increase the Mobility of Blind and Low-Vision Individuals - A Pilot Study

Objective: Blindness and low vision have severe effects on individuals' quality of life and socioeconomic cost; a main contributor of which is a prevalent and acutely decreased mobility level. To alleviate this, numerous technological solutions have been proposed in the last 70 years; however, none has become widespread. Method: In this paper, we introduce the vision-to-audio, super-scale sensory

Efterklokhet underminerar förmågan att avvärja terror

Analyzes of the terrorist attack on Drottninggatan have begun to be published. The risk is now that the debate will be governed by the logic of hindsight, that politicians and the media will be on the stands, pointing out mistakes and demand responsibility. Such a climate jeopardizes in the long run the development of our ability to prevent terrorist attacks, write four security researchers.

Sources of error for single-shot PMT-based phosphor thermometry in harsh conditions

This study investigates photomultiplier tube (PMT) nonlinearities, relevant for lifetime phosphor thermometry, at various decay times to assess and minimize the impact on temperature measurement accuracy. The focus is single-shot measurements performed in harsh environments where phosphor signal attenuation often is a concern. The sensitivity of decay time measurements to changing phosphorescence

Serum Glycine Levels Are Associated with Cortical Bone Properties and Fracture Risk in Men

Context: In a recent study a pattern of 27 metabolites, including serum glycine, associated with bone mineral density (BMD). Objective: To investigate associations for serum and urinary glycine levels with BMD, bone microstructure, and fracture risk in men. Methods: In the population-based Osteoporotic Fractures in Men (MrOS) Sweden study (men, 69-81 years) serum glycine and BMD were measured at b

Readout of Quantum Screening Effects Using a Time-Dependent Probe

In voltage- and temperature-biased coherent conductors quantum screening effects occur if the conductor's transmission is energy dependent. Here, we show that an additional ac-driven terminal can act as a probe for a direct readout of such effects, hitherto unexplored. We find that screening of charges induced by the static biases impacts already their standard linear thermoelectric response coeff

Fra det syriske voldskaos er der opstået en ny litterær strømning, der er kendetegnet ved at være meget sanselig og kropslig. Død, blod og afrevne lemmer er gennemgående elementer i teksterne, der beskriver, hvordan krigen besætter hverdagen og fører helt nye lugte- og sanseindtryk med sig. Teksterne er et vidnesbyrd om volden og bryder med en litterær tradition i Syrien, hvor censur og afstraffelArticle in Danish on new Syrian literature written after the militarization of the popular uprising. As a consequence of the violence and destruction, this literature is very bodily and full of sense perceptions of the new war reality. The article presents literary examples written by the Syrian poet Rasha Omran and the Syrian novelist, poet, and journalist Khalil Sweileh.

Transient dynamics of a magnetic impurity coupled to superconducting electrodes : Exact numerics versus perturbation theory

Impurities coupled to superconductors offer a controlled platform to understand the interplay between superconductivity, many-body interactions, and nonequilibrium physics. In the equilibrium situation, local interactions at the impurity induce a transition from the spin-singlet to the spin-doublet ground state, resulting in a supercurrent sign reversal (0-π transition). In this work, we apply the

Exploring the Associations Among Occupational Balance and Health of Adults With and Without Inflammatory Arthritis

Objective: Occupational balance is a person's subjective perception of the amount and variation of their everyday activities. Evidence suggests an association between occupational balance and health. However, the impact of arthritis on occupational balance and its association with health is unclear. This exploratory study was undertaken to examine associations between occupational balance and meas

The Art of Listening in the Gospel of Matthew and Paul’s Letter to the Romans

This revised lecture highlights two aspects of listening in the Bible, that of listening as an obedient act of confession according to the Gospel of Matthew and that of listening to and interpreting the oral performance of Paul’s letter to the Romans. The former aspect is specific to the socio-religious commitment in ancient Israel and Judaism, including the Jewish Christ-believers, and identifiesThis revised lecture highlights two aspects of listening in the Bible, that of listening as an obedient act of confession according to the Gospel of Matthew and that of listening to and interpreting the oral performance of Paul’s letter to the Romans.

Establishing Coupled Models for Estimating Daily Dew Point Temperature Using Nature-Inspired Optimization Algorithms

Potential of a classic adaptive neuro-fuzzy inference system (ANFIS) was evaluated in the current study for estimating the daily dew point temperature (Tdew). The study area consists of two stations located in Iran, namely the Rasht and Urmia. The daily Tdew time series of the studied stations were modeled through the other effective variables comprising minimum air temperature (Tmin), extraterres

Hypothalamic expression of huntingtin causes distinct metabolic changes in Huntington's disease mice

OBJECTIVE: In Huntington's disease (HD), the disease-causing huntingtin (HTT) protein is ubiquitously expressed and causes both central and peripheral pathology. In clinical HD, a higher body mass index has been associated with slower disease progression, indicating that metabolic changes may be involved in disease pathogenesis. Underlying mechanisms of metabolic changes in HD are not fully known,
