Remodeling and Application of Stock Option Price Based on Skewed Laplace Distribution Approach

This paper proposed a new model to price a stock option based on the Skewed Laplace distribution approach (SLOP). The approach was considered to provide a better option price than Black Scholes Option Price (BSOP) because Skewed Laplace distribution (SL) has a shape parameter tha...

Hidden Spillovers of Human Development: Enclave Panel Threshold SAR Evidence from West Java

This study examines the spatial spillover dynamics of the Human Development Index (HDI) in West Java Province, Indonesia, using the Enclave Panel Threshold Spatial Autoregressive (E-PT-SAR) model and panel data from 27 districts during 2021–2025. The model extends the conventiona...

On a divisibility condition related to the sum of element orders of a finite group

Given a finite group G, we denote by [Formula: see text](G) the sum of element orders of G. In this note, we determine finite groups G such that [Formula: see text]H[Formula: see text] – [Formula: see text]K[Formula: see text] divides [Formula: see text](H) – [Formula: see text](...

Optimal Acyl Chain Length for Imparting Rigidity and Water Resistance to Cellulose–Hydroxyapatite Composites

An acylation reaction was performed on the crystalline surface of cellulose in a composite consisting of microfibrillated cellulose (MFC) and hydroxyapatite (HAP) with an inorganic weight fraction of 68%. The composite was acylated using acetic anhydride, propanoic anhydride, and...

Probing dark matter and phantom field effects on neutrino oscillations around black holes

Abstract This study investigates how dark matter in the background of the phantom field (DMPF) near a black hole influences neutrino flavor oscillations using a two-flavor model. It is found that gravitational effects are cancelled for radially moving neutrinos, causing the oscil...

Self-regulatory strategy use in exam preparation: reflection and automaticity shape successful self-regulation

In a preregistered reanalysis of two longitudinal studies (N = 200, N = 294), we examined students’ self-regulation during exam preparation. Assessments included a baseline, twice-weekly measures over two weeks, a fourth-week questionnaire, and (in Study 2) a follow-up on exam gr...

Gut Microbial Metabolism as a Dynamic Interface in Neurodegenerative Diseases

Gut microbial metabolites serve as functional mediators of gut–brain communication, linking microbial alterations to neurodegenerative pathology. How metabolite profiles shift during disease progression and interact with host genetic susceptibility remains poorly characterized. T...

Conditional bidirectionality between climate policy acceptance and perceived effectiveness

Abstract The causal relationship between climate policy acceptance and perceived effectiveness is contested. Traditional models assume effectiveness perceptions drive acceptance, while alternative accounts suggest the reverse. Additionally, whether general climate policy support...

Turbulent Frictional Drag of Weighted Fracturing Fluids in Pipes: Experiments and Large-Eddy Simulations

As the development of deep oil and gas resources advances continuously, the role of weighted fracturing fluids in reducing wellhead operating pressure becomes increasingly important. However, the turbulent frictional drag behaviors of weighted fracturing fluids in pipes have not...

Maternal Immunization Against Respiratory Syncytial Virus: An Updated WAidid Consensus Document on Evidence, Implementation, and Public Health Priorities

Background: Respiratory syncytial virus (RSV) is a major cause of lower respiratory tract disease and hospitalization in early infancy. The availability of maternal RSVpreF vaccination and long-acting infant monoclonal antibodies has created two effective but operationally distin...

Comparative Performance of Classical Statistical and Machine Learning Models for Melanoma Classification

Early and accurate classification of melanoma is essential for improving patient outcomes and supporting clinical decision-making. Although numerous predictive models have been proposed, comparisons between classical statistical approaches and modern machine learning algorithms a...

Identification by UPLC-DAD of Phenolic Compounds from Native Nectariferous Flowers and Their Associated Honeys from Yucatán, Mexico

Honey biosynthesis is a biochemical transformation process in which nectar-derived phenolic compounds undergo selective modification during collection, enzymatic processing and maturation within the hive. This study investigated the influence of geographical origin (GeO), botanic...

Biomimetic Chromatography Profiling of a Neurotoxicology-Relevant Compound Panel: A Physicochemical Dataset for New Approach Methodologies

Developmental and adult neurotoxicity are hard to assess with conventional in vitro assays, which rarely account for how a chemical actually distributes once inside the body. Biomimetic chromatography offers a practical way to fill that gap, using stationary phases that mimic pho...

A grounded theory of practice learning: What, and how, do students learn during practice placements and how can this learning be maximised?

Introduction: With ever increasing pressures on healthcare services and a rising demand for placement opportunities to enable the education and registration of greater numbers of healthcare professionals, it is vital that students gain maximum learning during placement opportunit...

A FAIR annotated set of 60k+ in situ zooplankton images from the Greater North Sea and Greenland

Abstract. The North Sea is a productive shelf sea with a wide variety of hydrographic and biological conditions. It is subject to high anthropogenic pressures, including climate change, terrestrial nutrient loading, and the development of offshore wind farms, and the associated e...

Engineered genomic attachment sites for site-specific recombinases enable high-efficiency integration in plants and human cells

Abstract Here we developed a DNA-centric strategy for optimizing site-specific recombination by rationally engineering chimeric attachment sites. The high-activity att variants enhance Bxb1-mediated integration efficiency in human cells and plants. Among these att variants, the e...

Expelled Food Vacuoles as Protozoan-Derived Vehicles for Bacterial Persistence and Transmission

Abstract Protozoa are major bacterial predators in aquatic, soil and host-associated environments. During feeding, bacteria are internalised into food vacuoles, which normally mature into digestive vacuoles containing the molecular machinery required for bacterial digestion. Howe...

Progress and Perspectives on Thermal Design Methods of Machine Tools: A Critical Review

Thermal error remains a primary bottleneck limiting the machining accuracy of preci-sion CNC machine tools. As a proactive, source-level countermeasure, thermal design has become increasingly critical for enabling next-generation high-performance ma-chine tools. This paper presen...

The longitudinal interplay between acculturation and intergroup contact in adolescence

Abstract In current multicultural societies, mutual adjustment of majority and ethnic minority groups is a crucial issue shaped by groups' acculturation preferences and their encounters. These aspects are particularly relevant in adolescence when young people extend their social...

Real-World Outcomes of Fusion-Directed Targeted Therapy in Advanced Non-Small Cell Lung Cancer Harboring Actionable Gene Fusions

Actionable ALK, ROS1, RET, NTRK, and NRG1 fusions define biologically distinct subsets of advanced non-small cell lung cancer (NSCLC), yet real-world data across these rare populations remain limited. We retrospectively evaluated patients with advanced NSCLC treated at Memorial H...
