Measuring the drawdown risk and recovery potential of self-regulatory organizations in response to war events

Purpose The purpose of this study is to assess the impact of war events on the performance of self-regulatory organizations (SROs), specifically equity markets. Furthermore, it is segregated into classifications: developing, emerging, stand-alone and frontier regions, including A...

Development and validation of a theoretical test for ultrasound-guided biopsy competence in the head and neck

PURPOSE: This prospective study is designed to test the validity of a multiple-choice question (MCQ) test in assessing theoretical knowledge of ultrasound-guided fine-needle aspiration biosy and core-needle biopsy of the head and neck. METHODS: Seven international experts reached...

Improved forecasting of spring flood volume and low-flow discharge in the Buktyrma river (Kazakhstan) using hydrometeorological and soil–water indicators

Abstract Accurate forecasting of spring flood volume and low-flow discharge is essential for water resources management and flood risk mitigation, particularly in mountain basins with snow-dominated hydrology. This study proposes an enhanced statistical approach to predict these...

Mineralogy and thermobarometry of marbles: constraints on retrogression and hydrothermal imprint in a polymetamorphic terrane (Făgăraș Unit, Southern Carpathians, Romania)

Abstract This thermobarometry study employs calcite-dolomite solvus thermometry and thermodynamic pseudosections applied to marbles in the Făgăraș Unit, the uppermost unit of the Variscan metamorphic basement of the Alpine Supragetic units, Central Southern Carpathians. The marbl...

Influence of geometry on the collapse of masonry arches under horizontal loading

Abstract Kinematic limit analysis is widely used to identify collapse conditions in masonry arches. The collapse configuration can be defined by the hinge positions corresponding to the minimum collapse multiplier. The kinematic evolution of the mechanism may represent a compleme...

Spectral Endomorphism Factorization and Exceptional Degree-Two Root Correspondences in Codimension-Three Lefschetz Failure

Let $X$ be a smooth rational surface obtained by resolving the generically reduced quadratic-root correspondence attached to a controlled codimension-three weak Lefschetz failure. The preceding Pfaffian analysis produces a pulled-back rank-two quotient bundle $Q$, a nowhere-zero...

Do collagen membranes with different thickness-related mechanical properties affect the outcomes of lateral bone augmentation? An immunohistochemical analysis

OBJECTIVES: This study evaluated immunohistochemical profiles associated with guided bone regeneration (GBR) using collagen membranes with different thickness-related mechanical properties to characterize membrane-related biological responses during lateral bone augmentation. MET...

Currency transition: the use of foreign coins and ‘dollarization’ in seventeenth-century Ottoman Istanbul

This article investigates the seventeenth-century Ottoman Empire’s transition from domestic to foreign currency, a striking episode in early modern monetary history. Drawing on over 22,000 Istanbul court records, we provide the first large-scale quantitative account of how Europe...

Observation Transport and Synchronization Contracts in Finite Legal Reply Systems of Shogi

A legal candidate move in shogi induces a finite system of all legal replies. Previous work represented such a system by reply observations, discernibility sets, an inclusion-minimal discernibility skeleton, and a profile symbol. This paper studies what happens when the observati...

Promotion strategy of electric vehicle in the post-subsidy era: empirical evidence from China

Abstract Financial incentive policies have played a crucial role in cultivating the electric vehicle market during its initial development stage. However, as subsidies decline, how governments can effectively adjust policy strategies to sustain market growth has become a critical...

Diabetes Mellitus and Long-Distance Running: A Systematic Review

BACKGROUND: Athletes with diabetes increasingly participate in endurance running, benefiting from physiological adaptations and technological advances like continuous glucose monitoring (CGM) for glycemic control. So far, no comprehensive review summarizing the current knowledge...

Discernibility Profiles and Mechanism Repertoires of Legal Reply Systems in Shogi

For a fixed legal shogi position and a legal candidate move, consider the complete finite set of legal replies. We observe each reply through three shogi-specific components: actor action edges lost after the reply ($\Lost$), actor action edges newly gained ($\Gain$), and the com...

A single species, different repeatomes? Genomic plasticity in Passiflora foetida L. complex and comparative insights across the subgenus Passiflora

The genus Passiflora L. comprises approximately 650 species, and exhibits high diversity in the Neotropics, especially the subgenus Passiflora. Several species of this subgenus have an abundant repetitive fraction, consistent with their increased genome sizes. However, the repeti...

Resonant Terminal Layers and Critical Interfaces in Finite Collatz Bridges

We study finite orbit segments of the shortcut Collatz map in shifted coordinates. A terminal word is called multiplier-supercritical when its linear multiplier exceeds one. For a bridge ending at height $k$ with overshoot $U$, we prove an exact depth-by-depth criterion for termi...

Degeneracy of the Garriga–Mukhanov Perturbation Variables at Time-Symmetric Surfaces

This preprint identifies a domain-of-validity failure in the Garriga-Mukhanov perturbation variables for curved cosmological models at time-symmetric surfaces, where the Hubble rate and background field velocity both vanish.It derives a universal inverse-square divergence in the...

Can Large Language Models Support University Counseling? Evidence from Perceived Counseling Alliance, Disclosure Willingness, and Risk Recognition

The rapid expansion of large language models (LLMs) has created new opportunities for university mental health services, particularly in contexts where counseling demand exceeds available professional resources. This study examined the application of an LLM-based intelligent agen...

Microbiota Dynamics and Listeria monocytogenes Inhibition in Vacuum-Packed Brown Bear Meat Treated with β-Cyclodextrin-Encapsulated Essential Oil

Abstract This study evaluated the microbiological quality and microbiota dynamics of brown bear ( Ursus arctos ) meat treated with β-cyclodextrin inclusion complexes of Origanum vulgare essential oil (OVEO/β-CD) and Illicium verum essential oil (IVEO/β-CD) during 21 days of refri...

Flooding temperature affected corn (Zea mays L.) emergence and root growth

Abstract Background and aims Early season weather fluctuations significantly impact corn ( Zea mays L.) seedling establishment and soil nitrogen availability. This study investigated the effect of flooding duration and temperature after planting on corn emergence, seedling biomas...

Association between skeletal maturation and the developmental stages of the maxillary canine and mandibular second and third molars across different vertical facial patterns

Abstract Background Skeletal maturation and dental developmental stages are widely used indicators of biological growth in orthodontics. This study aimed to evaluate the association between skeletal maturation and the developmental stages of the maxillary canine (U3) and mandibul...

Unified Classification of Physical Asymmetries — Seven Fundamental Types Based on the Information Dissipation Tensor and Their Physical Manifestations

The understanding of symmetry breaking in physics has long followed a "phenomenon-discovery, theory-explanation" pattern. Parity violation, C violation, and CP violation — all were first observed experimentally and then explained theoretically. This paper demonstrates how the Ord...
