Leak-safe functional forecasting of daily variance: window-to-curve predictors for DAX Rogers–Satchell variance

Abstract We study one-step-ahead forecasting of daily DAX equity-index variance under an explicit information-availability design. The target is the Rogers–Satchell range-based variance proxy computed from open–high–low–close (OHLC) data, and predictors are daily log returns, wit...

Factors related to prenatal depression among hospitalized high-risk pregnant women in South Korea: a cross-sectional study focused on resilience, pregnancy stress, and marital satisfaction

PURPOSE: Prenatal depression affects 10%-25% of pregnant women and has important implications for maternal and neonatal health. High-risk pregnant women may be particularly vulnerable to anxiety and depression because of obstetric complications and concerns about fetal health. Th...

Mesoporous Magnetic Nanoparticles Functionalized With Quaternary Ammonium Salts as Targeted Nanocarriers for Doxorubicin Delivery in Breast Cancer Therapy

Background: Nanotechnology offers promising strategies to overcome major limitations of conventional cancer chemotherapy, including poor targeting, systemic toxicity, and low drug bioavailability. This study focuses on developing a biocompatible magnetic nanocarrier modified with...

Derivation of Pediatric Emergency Preparedness Checklist for Urgent Care Centers

OBJECTIVES To develop a consensus-based pediatric emergency preparedness checklist tailored for urgent care centers, addressing policies, procedures, personnel, equipment, and medications necessary to stabilize critically ill or injured children prior to transfer. METHODS A modif...

The general mental health conditions and related factors of the occupational health physicians working in Ankara Province

This study aimed to evaluate the personal and occupational factors associated with the general mental health status of occupational physicians. In this cross-sectional survey, data were collected through a self-administered online survey consisting of the General Health Questionn...

Position paper : Evolution as Virus principle - The basic mechanism of reproduction in plants and animals

This position paper formulated one ontological Redefining evolution. It shows that viruses are not only temporary activated patterns are those whose existence exclusively in the inner Water area living cells possible is , rather that she at the earliest Reproductive mechanism rep...

Kinetically controlled shock-wave route to turbostratic boron-carbon-nitride nanosheets

Turbostratic boron carbon nitride (tBCN) is highly attractive for energy storage and catalysis owing to its rotationally disordered stacking and expanded interlayer spacing, yet direct synthesis of tBCN with high in-plane crystallinity remains challenging. Here, we demonstrate th...

Parents in the making: A critical encounter between bioethical theory and “Homegrown” accounts of moral parenthood

In this paper, we explore questions of moral parenthood by setting up a critical encounter between accounts developed by bioethicists and the perspectives of prospective PACT (Pre-conception Agreement-Based Co-parenting Together-apart) parents. This particular approach attends to...

The evolving role of TP53 mutation in hepatocellular carcinoma (HCC)

Hepatocellular carcinoma (HCC) is one of the most common cancer types globally, which is characteristically aggressive, with a poor prognosis and a high mortality rate. The pathways leading to the development and progression of this fatal disease have been studied at the macro an...

DNA metabarcoding improves detection of rare and volant prey in the diet of feral cats (Felis catus)

Context Cats (Felis catus) have contributed to the extinctions of more than 60 vertebrates and continue to be a major conservation threat globally. Conservation managers traditionally record the diet of cats from morphological (manual) searches of stomach or scat samples. However...

From Mining Informality to Public Financial Capacity: An Institutional Approach to the Formalization of Artisanal Mining Value Chains in the Democratic Republic of Congo

This concept note proposes an innovative institutional approach to the formalization of artisanal and small-scale mining (ASM) value chains in the Democratic Republic of Congo (DRC). Grounded in institutional economics and political philosophy, the research challenges purely coer...

Computational and experimental evaluation of bismuth modification in CsPbX3 (X = I− or Br−): Impact on structural and optical properties

In this work, the effects of partial substitution of Pb 2+ by Bi 3+ at the B-site of CsPbI 3 and CsPbBr 3 perovskites on their structural and optical properties were evaluated using an integrated approach combining Density Functional Theory (DFT) calculations and experimental res...

Common thought patterns reflect generosity, fairness, and social context

Abstract Humans generate thousands of thoughts each day, many of which concern other people. Yet it remains unclear whether these ongoing thoughts vary systematically across social contexts that demand meaningful social behavior, and whether they reflect individual differences in...

Aum Shinrikyo and the AI Uplift Problem: How LLMs Could Lower the Threshold for CBRN Harm

This case study examines how large language models could lower the barriers to chemical, biological, radiological, nuclear, and explosives harm by improving access to technical knowledge, troubleshooting, interpretation, and operational decision-making. Using Aum Shinrikyo as a h...

The Pythagorean Angle Lattice: Angle Hierarchy and Spectral Structure

Every primitive Pythagorean triple generates an infinite angle-halving hierarchy that recovers the metallic means precisely when c−b equals 1, 2 or 8, and naturally produces a convergent spectral zeta function. We study the Pythagorean Angle Lattice, a countable set of real numbe...

Association of COVID-19 infection with welfare recipients in Japan: a retrospective cohort study

Abstract Background The COVID-19 pandemic has exacerbated poverty among vulnerable populations worldwide. However, no study has clarified the extent to which COVID-19 infection increases the likelihood of becoming a welfare recipient in Japan. Therefore, we examined the associati...

A scoping review of patient self-disclosure assessment tools in healthcare settings

To conduct a scoping review of patient self-disclosure assessment tools both domestically and internationally, and to provide a reference for the selection of clinical assessment tools or related research. This scoping review was conducted in accordance with the methodological fr...

Transcriptomic and RNAi-mediated antiviral response to Kamiti River virus infection in Aedes albopictus U4.4 cells

Mosquitoes transmit arboviruses that represent major global public health challenges. Increasing insecticide resistance and absence of effective antiviral therapies underscore the need for novel vector control strategies. Insect-specific viruses have emerged as candidates for bio...

Mapping the adoption and implementation of artificial intelligence (AI)-based conversational interface for tobacco cessation: a scoping review protocol

Abstract Background Tobacco use remains a leading global public health issue, accounting for nearly 8 million deaths annually. Despite ongoing efforts through various health interventions and programmes aimed at tobacco cessation, significant challenges persist, particularly in l...

Perioperative tranexamic acid and postoperative haematuria after transvesical prostatectomy: a prospective observational cohort study

Bleeding and postoperative haematuria remain clinically relevant after open simple prostatectomy. Tranexamic acid (TXA) may reduce bleeding through antifibrinolytic activity, but evidence in open prostate surgery for benign prostatic obstruction is limited. This study evaluated p...
