Comparative Surface and Early Biological Responses of α ‐, α + β ‐, and β ‐Type Titanium Alloys

This study investigates the surface and early biological responses of three titanium (Ti) alloys with different phase constitutions and alloy chemistries. Commercially, pure Ti (CP‐Ti), Ti‐6Al‐4V, and Ti‐45Nb were selected as representative α ‐, α + β ‐, and β ‐type alloy systems...

Metabolic characteristics and evolutionary history of the nitrogen-fixing cyanobacterial endosymbionts of pennate diatoms

Abstract Nitrogen-fixing cyanobacteria are important sources of bioavailable nitrogen on Earth. Some nitrogen-fixing cyanobacteria are endosymbionts of algae, and recently one of them, UCYN-A2, was shown to be an early-stage organelle (nitroplast) of haptophytes. These biological...

DBFA-Net: Diffusion-Based Bidirectional Fusion and Axial Attention Network for medical image segmentation

In recent years, Denoising Diffusion Probabilistic Models (DDPMs) have shown strong modeling capability and are increasingly applied to medical image segmentation tasks. However, existing diffusion models still struggle with fine-grained structures and multi-scale context, partic...

Representative Bureaucracy in Private Philanthropy: Testing Discretion and Racial Representation in Community Foundation Grantmaking

As public service delivery increasingly involves non-governmental actors, public administration theory needs to examine how its core frameworks operate beyond traditional bureaucracies. This study extends representative bureaucracy theory to private philanthropy, an increasingly...

Climate change worry and generalized anxiety among high school students in a rural district of Türkiye: a cross-sectional study

Climate change is increasingly recognized as a threat to adolescent mental health, yet data on climate-related worry among high school students in rural settings are scarce. This study aimed to determine the level of climate change worry among high school students in a rural dist...

Effect of waste steel shavings on strength characteristics of compacted cold mix asphalt

Traditional hot mix asphalt for pavements has a high carbon footprint, necessitating cleaner alternatives like cold mix asphalt (CMA) with strong mechanical performance. Cementitious fillers improve CMA properties, while waste steel shavings further enhance them for more durable...

WAGRL: A Wind Adaptive Guidance Framework for Uncertainty-Aware UAV Trajectory Control

To address the challenges of wind-induced uncertainty, decision inconsistency, and safety risks in quadrotor trajectory tracking, this study presents a Wind Adaptive Guidance Reinforcement Learning (WAGRL) framework. Unlike conventional controllers relying on fixed aerodynamic mo...

Fragility of steel transmission monopoles under hurricane wind loading: Part II - Dynamic framework and comparative assessment

This preprint extends the parametric fragility framework of Part I to the dynamic response of steel transmission monopoles to turbulent hurricane wind. Wind loads are described by Kaimal spectra, the response is obtained by modal superposition, and failure is the first exceedance...

Chamber‐Specific Morphometry and Quantitative Cardiac Histology in the Broad‐Snouted Caiman ( Caiman latirostris )

Quantitative cardiac morphology remains poorly documented in crocodilians. Hearts from four commercially reared male Caiman latirostris were examined by gross morphometry, histology, stereology, reticulin staining and Masson's trichrome. Relative heart mass averaged 0.125% of bod...

Research on the mechanism of linking time pressure to career growth among hotel employees

Research overlooks how and why identical cognitive appraisals of time pressure translate into divergent coping behaviors. Drawing upon the cognitive appraisal theory of stress, this study investigates the mechanisms linking time pressure to the career growth of frontline hotel em...

Effectiveness of the “sliding eight” technique for the treatment of upper eyelid ptosis

OBJECTIVE: This study evaluated the effectiveness and reliability of suspension surgery using the "sliding eight" technique with a polypropylene thread in patients with severe upper eyelid ptosis over a long-term follow-up period. MATERIAL AND METHODS: The study included 107 pati...

Bassam's Unified Quantum Theory

We now present the equations and coordinates of Bassam Muwaffaq Salman contained in Bassam’s Unified Quantum Theory. Bassam’s fundamental time equation: t_B = S_VN/π. Bassam’s fundamental spatial equation: L_B = (S_VN/π)·λ_0. Bassam’s fundamental mass spectral equation: m_B,n = m...

Evolutionary Diversification and Functional Roles of MYB Transcription Factors in Algae: Insights from Genomic Distribution and Regulatory Networks

MYB transcription factors (TFs) represent a conserved family of DNA-binding regulators involved in diverse cellular and physiological processes. MYB TFs are well-characterized in terrestrial plants, but their evolutionary history and functional diversity in algae remain poorly un...

Environmental drivers of rotenone persistence in stream fish eradications

Abstract Objective Although rotenone has been used to remove nonnative fish populations in the United States since 1934, the factors influencing its persistence remain unclear, even though under- and overapplication have substantial social, financial, and ecological consequences....

Assessment of Cropland Abandonment and Vegetation Recovery on the Chinese Loess Plateau

Cropland abandonment alters agricultural land use and may enable improvements in vegetation cover. On the Chinese Loess Plateau, the extent and spatial variation of these changes remain critical questions for land management. This study used annual land-cover trajectories to iden...

Does limb specialization in track and field introduce asymmetry in dynamic stability?

Limb dominance is routinely assessed through self-report, often referring to the preferred limb for kicking a ball. Subjective classifications inform a priori limb assignments for quantitative contrasts in functional tasks. The purpose of this study was to explore hop landing kin...

📣 PROMO READY #953 [Reddit r/algotrading] — E8 Intelligence live AI trading ecosystem — E8 Intelligence Research

📣 PROMO READY #953 [Reddit r/algotrading] — E8 Intelligence live AI trading ecosystem We've been running a live AI trading ecosystem off E8 geometry for 18 months now, and I wanted to share something concrete rather than another backtest screenshot. The core engine (Merlin) does...

Practical Engineering Foundations of the 64-Bit Goldilocks Prime Field (p = 2^64 - 2^32 + 1), Zero-Knowledge Virtual Machines (zkVM), and Index-Free Python Iterators: Eliminating Floating-Point Drift, Hardware Division Bottlenecks, and Fencepost Bugs in Modern Software Systems

In contemporary cryptography and verifiable computing, terms such as Finite Prime Fields (F_p), the Goldilocks Prime (p = 2^64 - 2^32 + 1), and Zero-Knowledge Virtual Machines (zkVM) often appear esoteric. Yet from a software and computer-architecture perspective, they are down-t...

Exploring foot pressure patterns for skiing experience classification in a simulator-based environment

Abstract This study investigated whether deep learning can distinguish groups of ski experience based on plantar-pressure distributions measured during simulator-based training and whether classifier outputs change during repeated training. Weight-shift images from 27 participant...
