Forecast-based attribution of the role of stratospheric variability in weather extremes

Abstract. Variability of the stratospheric polar vortex, particularly its dramatic breakdown during sudden stratospheric warming (SSW) events, has been linked to a number of surface weather extremes. However, attributing the role of stratospheric variability in a specific observe...

Development and internal validation of the Low Cardiac Index Score: a simplified bedside tool for continuous intraoperative screening

<title>Abstract</title> Purpose Advanced haemodynamic monitoring of cardiac index is restricted to selected high-risk cases, leaving most patients undergoing major surgery without real-time assessment. We aimed to develop and internally validate a simplified bedside score for con...

The Alphabet from the Sky: a documented construction

The Sefer Yetzirah, Sefer Raziel, and Gaffarel (1629) state that the twenty-two Hebrew letters were forged from the sky (3 mothers / 7 doubles / 12 simples = 3 axes / 7 wanderers / 12 signs) and that the ancients read the heavens as a text of letters. The computation verifies tha...

High-level prediction of continuous speech during mind-wandering

Abundant evidence shows that when listening to speech or reading text, we continuously make high-level predictions about upcoming words – their content, meaning, and relationship to the overall narrative. Does this process stop when our mind wanders away and conscious experience...

Performance Estimation and Ex Vivo Validation of Untethered Magnetic Robots in Soft Tissue

ABSTRACT The navigation and control of untethered magnetic robots (UMRs) within soft brain tissue critically depend on their ability to maintain synchronized rotation under applied rotational magnetic fields. The fundamental upper limit of this magnetic synchronization, known as...

Triangulated Dialogic Space in Arts and Design’s Studio Pedagogy

Despite decades of research demonstrating the learning benefits of dialogic pedagogy, its implementation in K-12 classrooms remains rare. Three structural challenges account for the difficulties of initiating and sustaining dialogic space in classrooms: managing face-threatening...

Clinical and radiographic outcomes of pulpotomy in primary molars using bioceramic putty versus formocresol: a retrospective cohort study

This retrospective cohort study compared the clinical and radiographic outcomes of pulpotomy in cariously exposed primary molars treated with bioceramic putty (BCP) or formocresol (FC) in a private pediatric dental clinic in Tel Aviv, Israel. Records and radiographs of children a...

A novel glyco-inflammatory healing index for risk prediction after isolated coronary artery bypass grafting: a multicenter retrospective cohort study

The Glyco-Inflammatory Healing Index (GIHI), calculated as HbA1c × C-reactive protein / albumin, integrates measures of glycemic control, systemic inflammation, and nutritional status. Its association with postoperative outcomes after isolated coronary artery bypass grafting (CAB...

Temporalities of future governance: Modern and contemporary modalities in energy scenarios

In this article, we characterize two modalities of future governance by analyzing how scenarios are used in the energy sector. We argue that these modalities are underpinned by different temporalities: a linear temporality, where the present is a consequence both of the past and...

The development and validation of the questionnaire My Experience with ADHD Pharmacotherapy – Parent Report (ME WAPH-P)

Nonadherence to pharmacological treatment for attention-deficit/hyperactivity disorder (ADHD) is common among children and adolescents. Despite well-documented clinical and contextual barriers, to the best of our knowledge no dedicated tool exists to quantify parental challenges...

Complex linkage disequilibrium and quantitative trait loci in chicken

Abstract Linkage disequilibrium (LD) underpins mapping studies of Quantitative Trait Loci Regions (QTLRs). A common yet misled assumption assumes the closest sites to a significant marker as causative mutation candidates. We studied chicken LD of mapped chicken QTLRs for Marek’s...

Alignment between expanded carrier screening panels and conditions leading to PGT-M: a real-world cohort study

PURPOSE: To assess the extent to which expanded carrier screening (ECS) panels capture the genetic conditions for which preimplantation genetic testing for monogenic diseases (PGT-M) is performed. METHODS: A retrospective observational study conducted at a single university-affil...

Language-like statistical structure arises in learned signaling: evidence from birdsong

All languages have statistically coherent subsequences (e.g., words) whose frequency distribution follows a power law. These properties facilitate language learning in humans, making them good candidates for arising through cultural transmission as a way to help faithful transmis...

Eliminating serum dependency of bovine mesenchymal stem cell expansion via media composition and genetic screen

The advancement of cultured fat toward viable industrial production is currently hindered by economic and technical constraints, including the formulation of cost-effective, chemically defined culture media. This study addresses serum dependency in bovine mesenchymal stem cells (...

Local Sustained Delivery of Temozolomide via an Injectable Poly(Anhydride-Ester) Depot for Glioblastoma Therapy

Background/Objectives: Glioblastoma (GBM) remains one of the most aggressive primary brain malignancies, with limited therapeutic progress over the past two decades. Systemic administration of temozolomide (TMZ) is a pillar of clinical management but is constrained by poor brain...

At dawn we did not sleep. Contribution to the dawn of functional group translocation: ortho → para 1,3-acyl migration of 2-fluoroacetophenone

Abstract Functional Group Translocation (FGT) was defined ( Chem. Soc. Rev. 2026) as a transformation in which the molecular formula, the identity of the functional group, and the carbon framework remain unchanged, while only the bonding position of the functional group is altere...

Comparing Respiratory Support Modalities in Pediatric Asthma Exacerbation

Objectives: To compare clinical outcomes and racial disparities of children hospitalized for acute asthma exacerbation who required any respiratory support: invasive mechanical ventilation (IMV), non-invasive modalities (non-invasive ventilation (NIV) and high-flow nasal cannula...

The Concept of Theory and the Nature of Science: Reframing Science Education within the Discipline–Culture Paradigm

Abstract This study investigates the concept of theory , a notion central to understanding the nature and structure of scientific knowledge. In school science, theory is often introduced simply as the counterpart of experiment—its explanatory partner—and is used to account for la...

Emergency Care Needs in an Asymmetric Conflict: A Facility‐Based Cohort Study From Israel on October 7, 2023

ABSTRACT Background Due to the deteriorating global security situation, many countries are preparing their health systems for armed conflict. Wartime health care delivery is challenging due to the loss of territorial control and attacks on Emergency Medical Services (EMS). The ob...
