Discovery of a second-generation planet candidate accreting onto a white dwarf

Abstract Many white dwarfs accrete the debris of disrupted planetary bodies, detected in the form of metal enrichment in their atmospheres, dusty or gaseous circumstellar discs, and photometric transits from debris. The composition of accreted debris has been shown to be diverse...

Between Documents and Literature: Narration in the Pre-modern Islamicate World. A Special Issue in Honour of Prof. Miriam Frenkel

This special issue is dedicated to Prof. Miriam Frenkel and is inspired by her trail-blazing work bridging the perceived gap between documentary and literary texts. Broadly speaking, documentary te...

Stress, Support, and Resilience During Wartime: A Dyadic Longitudinal Study of Parental Exhaustion

ABSTRACT Objective This study aimed to broaden the understanding of how parental exhaustion evolves during war, and how war exposure and social support are associated with these changes within individuals and between partners. Background Wars exert strain on parents. The Balance...

The Role of Personality in Predicting Singlehood Status: Differential Effects of Big Five and Dark Triad Traits Over Time

ABSTRACT Objective The present study used the Pairfam longitudinal dataset to examine the effects of Big Five and Dark Triad personality traits on the probability of being single. Method Generalized linear mixed models with a within‐between decomposition distinguished stable indi...

Self-Fashioning in Front of a Distorting Mirror: Interwar Jewish Literature Gazing at Classical Chinese Poetry, or Second-Order Modernism

The modernist fascination with the Far East is a well-known phenomenon, driven among other things by the “decline of the West” zeitgeist. When adopted by peripheral communities involved in nation building, it often served other needs and, in the process, became distorted or dispr...

On the class of systems which are disjoint from every ergodic system

In this note, we give a fairly direct proof of a recent theorem of Górska, Lemańczyk and de la Rue which characterises the class of measure-preserving transformations that are disjoint from every ergodic measure-preserving transformation. Our proof works just as well for any coun...

Does Privacy Matter? Evidence from a Legal Reform

We investigate the impact of a unique legislative reform that granted anonymity to plaintiffs in court rulings for personal injury claims. Prior to the reform’s implementation in August 2015, claimants who rejected settlement offers faced the risk that court proceedings would pub...

ON THE CLASSIFICATION OF DEFINABLE CCC FORCING NOTIONS

Abstract We show that for a Suslin ccc forcing notion Q $\mathbb Q$ double struck upper Q adding a Hechler real, “ ZF + DC ω 1 + $\mathrm {ZF}+\mathrm {DC}_{\omega _1}+$ upper Z upper F plus upper D upper C Subscript omega 1 plus all sets of reals are I Q , ℵ 0 $I_{\mathbb Q,\ale...

Discrepancies Between SNOT-22 Questionnaire, Objective Assessments, and Histopathologic Findings in Chronic Rhinosinusitis With Nasal Polyps

Background The Sinonasal Outcome Test-22 (SNOT-22) is widely used to evaluate symptom burden in chronic rhinosinusitis with nasal polyps (CRSwNP), yet its relationship with objective disease measures, pathological features, and specific endotypes remains unclear. Objective To ass...

Carbapenemase-producing Kluyvera spp.: epidemiology of an evolving species

Abstract Background Kluyvera spp. are increasingly recognised as significant pathogens in humans. Recent reports of carbapenemase-producing (CP) Kluyvera spp. raise a concern that they may be disseminating carbapenemases to other species undetected. Research on CP-Kluyvera spp. i...

The structure of the vat dye pyranthrone, a regioselective double Scholl Reaction product

Abstract The structure of the vat dye pyranthrone (2), first synthesized by Scholl in 1912, formed by the double Scholl reaction (AlCl 3 /NaCl melt) of 1,6-dibenzoylpyrene (1), was verified for the first time by 1 H- and 13 C-two-dimentional correlation NMR spectroscopy in nitrob...

Deciphering temporal antifungal dynamics of a rare actinomycete via integrated omics

ABSTRACT Fungal phytopathogens pose a persistent threat to global crop production, and widespread use of fungicides has driven resistance development and environmental concerns, necessitating sustainable alternatives. Actinomycetes produce diverse bioactive metabolites, yet natur...

First detection of Leishmania infantum DNA in Phlebotomus (Larroussius) syriacus and its epidemiological implications in Israel

Abstract Background Phlebotomine sand flies (Diptera: Psychodidae) are the primary vectors of Leishmania parasites, the causative agents of leishmaniasis, one of the most important vector-borne diseases worldwide. In the eastern Mediterranean basin, Leishmania infantum is transmi...

Food-Related Attitudes among Holocaust Survivors and Second- and Third-Generation Descendants: A Cross-Sectional Cohort Study

Abstract The purpose of this study was to examine self-reported food-related attitudes and behaviors among Holocaust survivors and second- and third-generation descendants, and to compare responses across generational cohorts. This exploratory cross-sectional questionnaire study...

Auxin-induced parthenocarpy as an alternative to pollination of trellised sweet acorn squash grown under protection in fall and early winter

Sweet-fruited acorn squash are a premium-priced vegetable in Israel and are produced under field conditions in the spring and summer. They are also produced from plants grown trellised in screenhouses in the fall, for marketing after storage during the winter months. Ordinarily,...

Cortex-wide laminar dynamics diverge during learning

Learning to link sensory information to motor actions requires coordinated activity across the cerebral cortex, but how different cortical layers contribute to learning remains unclear. Here we show that learning engages distinct, layer-specific activity patterns across the corte...

Alteromonas macleodii breaches the diatom frustule triggering protoplast emergence and programmed necrosis-like death in Thalassiosira rotula

Abstract Diatom-bacteria interactions drive biogeochemical fluxes at the base of the marine food-web. Although bacteria are increasingly recognised as important drivers of algal mortality, the diversity of algicidal strategies remains understudied. Here we show that Alteromonas m...

Last-Passage Percolation and Product-Matrix Ensembles

Abstract We introduce and study a model of directed last-passage percolation in planar layered environment. This environment is represented by an array of random exponential clocks arranged in blocks, for each block the average waiting times depend only on the local coordinates w...

Monotonicity, topology, and convexity of recurrence in random walks

We consider nonhomogeneous random walks on the two-dimensional positive quadrant N2. In the 1960’s the following question was asked for N2: is it true if such a random walk X is recurrent and Y is another random walk that at every point is more likely to go down and more likely t...

Filipino migrant workers navigating war online: Digital performative citizenship and the construction of belonging during the Israel–Hamas war

Research on migrant workers’ use of social media has largely focused on everyday contexts. Little attention has been given to their practices during major crises in their host countries where they lack citizenship. This study examines how Filipino live-in caregivers in Israel use...
