Comparative Analysis of Bone vs. Tooth Anchored Maxillary Protraction in Cleft Lip and Palate Patients—A Systematic Review and Meta‐Analysis

open access: yesOrthodontics &Craniofacial Research, EarlyView.
ABSTRACT Management of class III malocclusion in patients with cleft is geared toward improving the maxillary position with maxillary protraction therapy with or without bone anchorage. This study aims at evaluating the effects of bone‐anchored maxillary protraction (BAMP) and tooth‐anchored maxillary protraction (TAMP) appliances in patients with ...

Prioritizing Inclusive Practices for Rural Women Smallholder Farmers Participation in Climate Change Adaptation and Ecological Education in Sub‐Saharan Africa

open access: yesClimate Resilience and Sustainability, Volume 5, Issue 2, December 2026.
Rural women smallholder farmers face climate change impacts alongside sociocultural barriers, limited resources, and restricted decision‐making power. A mixed‐methods review and participatory workshops identified 16 adaptation strategies and 13 inclusion practices, highlighting variation in stakeholder priorities. Organizational membership emerged as a

Analysis of Dynamics Characteristic of the Helical Gear Transmission in Helicopter

open access: yesJixie chuandong, 2015
The multiaxial helical gear transmission is widely used in helicopter for parallel operation. The dynamics model of the helical gear transmission is established for system inherent characteristic analysis,and the dynamic response is obtained.

A New Paradigm for Understanding the Rheology and Processability of Poly(p‐Phenylene Terephthalamide) Liquid‐Crystalline Solutions

open access: yesJournal of Applied Polymer Science, Volume 143, Issue 34, September 10, 2026.
Kevlar is traditionally modeled as a rigid‐rod polymer, yet rheological behavior deviates from this assumption. The review introduces a novel “twist‐tie” entanglement theory for aramid polymer chains in the nematic liquid crystal state, providing a molecular explanation for deviations from rigid‐rod models. Understanding twist‐tie entanglement dynamics

Investigating enzyme function by geometric matching of catalytic motifs

open access: yesProtein Science, Volume 35, Issue 9, September 2026.
Abstract The rapidly growing universe of predicted protein structures offers opportunities for data driven exploration but requires computationally scalable and interpretable tools. We developed a method to detect catalytic features in protein structures, providing insights into enzyme function and mechanism.

基于UG的渐开线斜齿圆柱齿轮参数化设计

open access: yesJixie chuandong, 2011
Parametric design is to use parameters to describe sizes of parts.When the part is designed,the shape of parts is changed by modifying characteristic parameters to achieve the sizes to drive the graphics.Cylindrical involute helical gear is a part of ...

A cofactor‐promiscuous HMGR from the Lyme disease pathogen illuminates diversity in bacterial isoprenoid biosynthesis

open access: yesProtein Science, Volume 35, Issue 9, September 2026.
Abstract The Lyme disease pathogen Borrelia burgdorferi contains a highly reduced genome lacking many primary metabolic pathways. However, B. burgdorferi retains the mevalonate pathway that synthesizes isopentenyl pyrophosphate (IPP), the precursor to the peptidoglycan carrier lipid.
