Influence of Cutting Wedge Geometry Design on Cutting Forces, Chip Formation and Surface Roughness During Free Machining of Aluminum Alloy

This study investigates the effects of the rake angle and clearance angle of custom-manufactured HSS-E Co5 high-speed steel cutting tools on the Fc main cutting force, the Fp passive force component, the Ra and Rz surface roughness parameters, and chip morphology during orthogona...

Ilamchetchenni

This paper examines Ilamchetchenni, an early Chola king known through Sangam Tamil literature. It focuses on his military achievements, particularly the Seruppazhi/Pazhi campaign, in which he is said to have defeated a Mauryan army that advanced into northern Tamilakam with the a...

Ultra-high-field MRI reveals a venous-dominant microbleed phenotype in cerebral amyloid angiopathy: a comparative study versus 3 Tesla MRI

<h3>BACKGROUND AND PURPOSE:</h3> Cerebral microbleeds (CMB) are core MRI markers of cerebral amyloid angiopathy (CAA). Ultra-high-field 7T MRI may improve CMB detection and visualization of venous-associated CMB (vCMB), but the extent to which this reflects additional lesion dete...

Broyden quasi-Newton-based parameter measurement method for thyristor-level components in converter valves without wire disconnection

To address the heavy workload of wire disconnection and reconnection, the measurement errors caused by external-circuit shunting, and the difficulty of obtaining specific component parameters using the comprehensive impedance method in field testing of damping and voltage-balanci...

Separating Behavioral, Latent, and Causal Commitment to Incorrect Answers in Large Language Model Reasoning: A Structured Critical Meta-Synthesis

The literature on multi-step chain-of-thought (CoT) reasoning increasingly claims that models become committed to incorrect answers mid-trace. We show that this shared vocabulary masks three non-interchangeable constructs—behavioral preference concentration, latent detectability,...

Fretting Wear and Corrosion Behavior of the Fe‐35Mn Biodegradable Alloy for Biomedical Applications

ABSTRACT The biodegradable Fe‐35Mn alloy has emerged as a promising material for temporary implants due to its excellent mechanical, degradation, magnetic, and biocompatibility properties. Despite these advantages, its in vivo performance can be affected by factors such as fricti...

Numerical Modeling of a Boundary Value Problem for a Singularly Perturbed Differential Equation with Two Boundary Layers Using the Spectral-Grid Method

This paper proposes a spectral-grid method based on Chebyshev polynomials of the first kind for the numerical solution of second-order singularly perturbed boundary value problems containing two boundary layers. The proposed method possesses several important advantages, includin...

Transcriptomic and metabolomic analyses reveal early coordination between redox homeostasis and phenylpropanoid metabolism associated with oat resistance to Drechslera avenae

Oat ( Avena sativa L.) is an important grain and forage crop, but oat leaf spot caused by Drechslera avenae ( D. avenae ) severely limits its production. However, the dynamic defense mechanisms underlying genotype-dependent resistance to this disease remain unclear. We characteri...

Geographic heterogeneity of Deinagkistrodon acutus venom: A multi-regional study of toxicity, proteomics, and antivenom efficacy

Snakebite envenomation caused by Deinagkistrodon acutus is a severe public health problem. Growing evidence indicates that snake venom exhibits obvious intraspecific geographic variation, which directly affects toxicity, organ damage, and antivenom efficacy. However, systematic s...

The Aspirational Scale Effect: A Theory of How Larger Goals Can Raise the Probability of Reaching Lower Thresholds

This paper introduces the Aspirational Scale Effect (ASE), a conceptual theory proposing that setting a substantially larger aspirational target can, under certain conditions, increase the probability of reaching a lower success threshold. The theory argues that larger goals can...

D3h Trigonal Prismatic Geometry Links Nuclear Spin Entanglement to Ligand Field Splitting — E8 Intelligence Research

FINDING: D3h trigonal prismatic geometry in coordination complexes is linked to nuclear spin entanglement in Posner clusters, with paramagnetic/diamagnetic behavior determined by ligand field splitting and electron pairing. MATH: - D3h point group symmetry: character table includ...

Why Does a Shallow Land Model Underestimate the Dryland Drying Trends?

Abstract Most land surface models (LSMs) and macroscale hydrological models with shallow soil profiles underestimate observed terrestrial water storage (TWS) declines across global drylands. Here, we incorporated a recently developed global data set of depth to bedrock with spati...

Increasing Climate Constraint on Vegetation Productivity Under Rising CO 2 in Northeast Asia

Abstract Elevated atmospheric CO 2 enhances vegetation productivity through direct physiological and indirect climate‐mediated pathways. However, how the balance between these mechanisms evolves under continued CO 2 rise remains unclear. Here, we use CMIP6 Earth system models to...

A collaborative e-library for stressor-response functions to improve the science underlying salmonid management

Stressor-response functions quantify relationships linking environmental stressors to biological responses, underpinning salmonid life-cycle models, restoration planning, regulatory policy, and cumulative effects assessments. Despite their importance, these stressor-response func...

Conjugation is Inversion Weighted by the Norm: A Unifying Identity for the Three-Field Model (Research Note 12)

Research Note 12 of the INDYNA program. This note studies the interplay of the Galois involution σ, the field norm, and coupling inversion g → 1/g in the conjugate-shell family: the three operations generate the symmetry group of the phase diagram, and their invariants classify t...
