New Formulas of Feedback Capacity for AGN Channels with Memory: A Time-Domain Sufficient Statistic Approach.

Recently, several papers identified technical issues related to equivalent time-domain and frequency-domain "characterization of the -block or transmission" feedback capacity formula and its asymptotic limit, the feedback capacity, of additive Gaussian noise (AGN) channels, first introduce by Cover and Pombra in 1989 (IEEE Transactions on Information Theory). The main objective of this paper is to derive new results on the Cover and Pombra characterization of the -block feedback capacity formula, and to clarify the main points of confusion regarding the time-domain results that appeared in the literature. The first part of this paper derives new equivalent time-domain sequential characterizations of feedback capacity of AGN channels driven by non-stationary and non-ergodic Gaussian noise.

Abattoir Countrywide Survey of Dairy Small Ruminants' Haemonchosis in Greece and Associated Risk Factors.

Objectives: The objectives of this study were to (i) determine the prevalence of infections in dairy sheep and goats in continental and insular Greece, based on an abattoir survey, and (ii) to evaluate potential host-related risk factors including the age and sex, as well as the altitude, the management system, the co-existence of goats and sheep, the season, and the anthelmintic treatment, on the occurrence of haemonchosis.

Methods: In total, 1004 abomasa of small ruminants were examined to evaluate the prevalence of spp. Moreover, a structured questionnaire was used to obtain relevant information regarding animal and farm characteristics.

Continental vs. Insular: Demographic and Growth Patterns in .

This study examines the demographic parameters, body size, survival rates, and growth dynamics of populations in continental (Botaş, Türkiye) and insular (Dipkarpaz, Northern Cyprus) habitats to understand how ecological constraints influence life-history traits. By integrating skeletochronological and morphometric analyses, we identified significant interpopulation differences. The continental population exhibited broader age ranges, higher survival rates, and less restricted growth, likely due to greater resource availability.

Study 1 employed qualitative research methods and identified 93 actions that people perform to manage relationship problems.

Evaluating the Pattern of Relationships of Speech and Language Deficits with Executive Functions, Attention Deficit/Hyperactivity Disorder (ADHD), and Facets of Giftedness in Greek Preschool Children. A Preliminary Analysis.

Speech and language deficits often occur in preschool children, and empirical studies have indicated an association between language impairments and challenges in different cognitive domains. The primary aim of the current study was to evaluate the associations between speech and language deficits, executive function (EF) impairments, Attention Deficit/Hyperactivity Disorder (ADHD), and aspects of giftedness in Greek preschoolers based on assessments from their teachers. Investigating the associations between aspects of EFs, ADHD, and giftedness was another objective of the current study.

Stbd1 stimulates AMPK signaling and alleviates insulin resistance in an in vitro hepatocyte model.

Starch-binding domain-containing protein 1 (Stbd1) is a glycogen-binding protein which localizes to the endoplasmic reticulum (ER) membrane and ER-mitochondria contact sites (ERMCs). The protein undergoes N-myristoylation, which is a major determinant of its subcellular targeting. Stbd1 has been implicated in the control of glucose homeostasis, as evidenced by the finding that mice with targeted inactivation of Stbd1 display insulin resistance associated with increased ERMCs in the liver.

The potential of depressive symptoms to identify cognitive impairment in ageing.

Depressive symptoms are common in mild cognitive impairment (MCI), dementia caused by Alzheimer's disease (AD dementia) and in cognitively unimpaired older adults. However, it is unclear whether they could contribute to the identification of cognitive impairment in ageing. To assess the potential utility of depressive symptoms to distinguish between healthy cognitive ageing and MCI and AD dementia.

Fetal genetic factors in pregnancy loss: Insights from a meta-analysis and effectiveness of whole exome sequencing.

Spontaneous pregnancy loss commonly occurs during the first trimester and can be caused by various factors including chromosomal abnormalities and submicroscopic aberrations. After the first trimester, the etiology of most pregnancy losses remains undetermined. This study aims to fill this gap by an in-depth investigation of the fetal genome and its effect on pregnancy outcome.

The International Work Addiction Scale (IWAS): A screening tool for clinical and organizational applications validated in 85 cultures from six continents.

Background And Aims: Despite the last decade's significant development in the scientific study of work addiction/workaholism, this area of research is still facing a fundamental challenge, namely the need for a valid and reliable measurement tool that shows cross-cultural invariance and, as such, allows for worldwide studies on this phenomenon.

Addressing Rotator Cuff-Related Shoulder Pain: Findings from a Greek Regional Observational Study Utilizing a Clinical Case Scenario.

: Rotator cuff-related shoulder pain (RCRSP) is a prevalent musculoskeletal issue, encompassing various shoulder conditions. While exercise typically forms the foundation of conservative treatment, there exists ongoing discourse regarding the effectiveness and role of passive treatments. International guidelines recommend initial conservative management, with surgery considered only after failed conservative treatment.

Development of quality indicators for hand osteoarthritis care - Results from an European consensus study.

Genetic relatedness of Staphylococcus aureus isolates within food outbreaks by single nucleotide polymorphisms.

Investigation of bacterial food outbreaks by whole genome sequencing can rely on the inspection of the genetic relatedness between isolates through the application of single nucleotide polymorphism (SNP) thresholds. However, there is no consensus for Staphylococcus aureus in the context of food outbreaks. In this study, we propose a SNP cut-off by taking into account the mutation rate and the evolution time of this pathogen in food.
