Histological reorganization and spatiotemporal distribution of cell wall epitopes during somatic embryogenesis in oil palm (Elaeis guineensis Jacq.)

Abstract Somatic embryogenesis is a key strategy for the clonal propagation of elite oil palm ( Elaeis guineensis Jacq.) genotypes. Although several protocols have been established, the structural aspects underlying the induction of embryogenic callus in this species remain unkno...

Human Hsp70 paralogs display selective J-domain interactions tuning proteostasis under stress

Hsp70 chaperones are central regulators of proteostasis, mediating folding, refolding, degradation, and aggregation-prevention. Their activity is tuned by the diverse J-domain proteins (JDPs), which both recruit client proteins and stimulate Hsp70 ATP hydrolysis via interaction w...

Louis IX’s letter to the French of August 1250 (Part 1): a new edition and translation

Louis IX’s letter to the French, written from Acre in 1250 upon the king’s decision to delay his return to France, is one of our key sources for the events of Louis’ crusade to Egypt in 1249-1250. The received text of the letter goes back to a mid-thirteenth-century manuscript (B...

Minkowski Bounds for Pasten's Arithmetic Derivative Lattices in the Squarefree Subfamily

This preprint studies the squarefree subfamily of the arithmetic-derivative lattices introduced by Hector Pasten. It proves an exact determinant identity and combines it with Vaaler's subspace lattice theorem to obtain explicit lattice-vector bounds. It further develops a structu...

A Modular Formalization of 2D Navier-Stokes Uniqueness in Lean 4: Sorry-Free 1D Gagliardo-Nirenberg and Axiomatic Reduction of the Ladyzhenskaya Argument

Abstract: We present a machine-checked modular formalization in Lean 4 (with Mathlib4) towards the formal verification of the 2D incompressible Navier-Stokes global uniqueness theorem. The package delivers two primary contributions: (1) A complete, 100% sorry-free formal proof of...

Frédéric Chopin's illness: a clinicopathological Conference 176 years after his death

Abstract This article revisits, in the format of a clinicopathological conference, the illness that led to the death of Frédéric Chopin at the age of 39 in 1849. Although tuberculosis has been historically accepted as the most likely cause, the authors propose an alternative hypo...

From disclosure to impact: How board diversity and independence drive corporate environmental performance under provincial corruption pressure?

Purpose This study aims to investigate how corporate boards shape environmental performance in Vietnamese manufacturing firms and examines whether province-level environmental corruption attenuates or amplifies these governance effects. Design/methodology/approach We manually con...

Reduced‐Port Versus Multi‐Port Laparoscopic Colectomy for Colorectal Cancer: A Systematic Review, Meta‐Analysis, and Meta‐Regression

ABSTRACT Background Reduced‐port laparoscopic colectomy (RPLC) has emerged as an alternative to multi‐port laparoscopic colectomy (MPLC) for colorectal cancer surgery, aiming to reduce operative morbidity and improve cosmetic outcomes. This systematic review and meta‐analysis eva...

Does Test Duration Matter? Comparing 1‐s and 5‐s Isometric Mid‐Thigh Pull Protocols for Performance Diagnostics in Basketball Players

ABSTRACT To compare kinetic characteristics of a 1‐s isometric mid‐thigh pull (IMTP) protocol with the traditional 5‐s protocol and examine their associations with basketball‐specific performance. Twenty‐five Tier 3 male basketball players performed standardized 1‐s and 5‐s IMTP...

The Unity of the Discrete and the Continuous as a Structural Principle: The Infinium △₁ₓ₁ and the Theory of Motives

This article is devoted to one of the oldest and deepest problems in mathematics—the gap between the discrete and the continuous. We show that this gap is not an accidental difficulty but a direct consequence of choosing the structureless point as the initial primitive. Within Δ‑...

Obturator hernia as a cause of small bowel obstruction in an 80-year-old female patient with comorbidities: management and challenges in a resource-limited setting: a case report

Abstract Background Obturator hernia is one of the rarest types of hernia and accounts for only a small percentage of small bowel obstructions. It may be asymptomatic, but most patients present with acute intestinal obstruction. Some patients may also report pain along the medial...

Loneliness as a Pathway from Social Isolation to Psychological Distress: A Cross-Sectional Mediation Study in Portuguese Adults

Social disconnection has become a public-health concern, but it remains unclear whether mental-health symptoms are more closely related to limited social contact or to the subjective experience of loneliness. This cross-sectional study examined 632 self-selected adults living in...
