Impact of Sugarcane Management Practices and Time Periods on Soil Organic Carbon and δ13C Signature After Paddy Rice Conversion

open access: yesLand Degradation &Development, EarlyView.
ABSTRACT Land use change (LUC) from paddy rice to sugarcane cultivation strongly influences soil organic carbon (SOC) stocks, with the extent and direction of change depending on residue management and time since conversion. This study aimed to (i) evaluate SOC stock changes under different residue management practices and conversion periods following ...

From Design to Implementation: NursingUP® Board Game for Positive Nursing Practice Environments

open access: yesResearch in Nursing &Health, EarlyView.
ABSTRACT Positive nursing practice environments are fundamental to patient safety, care quality, and nurses’ well‐being. However, few structured and evidence‐based interventions have been developed to actively strengthen these environments and foster collaboration among nursing teams.

Urban wild meat and pangolin consumption across southern forested Cameroon: The limited influence of COVID‐19

open access: yesPeople and Nature, EarlyView.
Abstract Overexploitation of wildlife is pervasive in many tropical regions, and in addition to being a significant conservation and sustainability concern, it has received global attention given discussions over the origins of zoonotic disease outbreaks.

Refractory Lung Diseases: From Cellular Structures, Molecular Mechanisms to Therapeutic Strategies

open access: yesPediatric Discovery, EarlyView.
ABSTRACT Refractory lung diseases (RLDs) encompass a spectrum of progressive pulmonary disorders, including acute respiratory distress syndrome (ARDS), bronchopulmonary dysplasia (BPD), and idiopathic pulmonary fibrosis (IPF). These conditions are defined by poor responsiveness to current therapeutic interventions and pose substantial clinical ...

Precision Stress Engineering in Tensegrity‐Inspired Nanoarchitectures Enabled by Size‐Affected Shrinkage

open access: yesSmall, EarlyView.
This work identifies a size‐dependent shrinkage effect that arises during polymer pyrolysis and uses it to embed residual stress into tensegrity‐inspired nanoarchitectures. By adjusting the dimensions of the structural elements, controlled prestress can be introduced in a simple and repeatable manner, enabling mechanically tunable nanostructures with ...

Optimal cube factors of Fibonacci and matchable Lucas cubes

open access: yes, 2018
The optimal cube factor of a graph, a special kind of component factor, is first introduced. Furthermore, the optimal cube factors of Fibonacci and matchable Lucas cubes are studied; and some results on the Padovan sequence and binomial coefficients are obtained.

Substitution of Ti by Nb in Maraging Steel: Effects on Strengthening Mechanisms and Crystallographic Behavior

open access: yessteel research international, EarlyView.
This work demonstrates that replacing Ti with Nb in maraging steel forms nanoscale Nb–Mo particles along boundaries, strengthening the alloy without relying on Ti phases. Heat‐treatment tuning promotes uniform crystal orientation and balanced grain boundaries, enabling strong yet ductile behavior.

Experimental study of the size effect on punching shear of steel fiber reinforced concrete slabs

open access: yesStructural Concrete, EarlyView.
Abstract As the behavior and design of steel fiber reinforced concrete slabs subjected to punching still remain an area of concern, the present work aims to provide a further contribution to the knowledge on punching behavior of slabs without transverse reinforcement.

New bounds in the discrete analogue of Minkowski's second theorem

open access: yesDiscrete Analysis
New bounds in the discrete analogue of Minkowski's second theorem, Discrete Analysis 2024:7, 6 pp. Minkowski's first theorem in the geometry of numbers states that if a closed centrally symmetric body $K$ in $\mathbb R^n$ has volume at least $2^n$, then
