Obstetrics and gynecology devices designed for low‐ and middle‐income countries: A narrative review

open access: yesInternational Journal of Gynecology &Obstetrics, Volume 169, Issue 1, Page 71-80, April 2025.
Abstract There are many barriers contributing to poor health outcomes for women in low‐ and middle‐income countries (LMICs), one of which is the lack of necessary medical devices. Presently, the development of various kinds of devices intended to improve women's health outcomes specifically in LMICs remains underrepresented in the literature; therefore,

Wearable photovoltaic textiles: From device technologies to long‐term reliability

open access: yesInfoScience, EarlyView.
Wearable photovoltaic textiles are highlighted as reliable energy sources that combine solar cell efficiency with hierarchical textile‐specific mechanical and environmental durability. Structural and encapsulation strategies, including planarization, neutral‐axis engineering, and advanced barrier designs, enable waterproofing, washability, UV shielding,

Targeting Renal IGFBP7 With Tetrahedral Framework Nucleic Acid‐Delivered siRNA Alleviates Acute Kidney Injury

open access: yesiNew Medicine, EarlyView.
A tFNA‐based siRNA delivery system targeting IGFBP7 effectively silences IGFBP7 expression and attenuates renal dysfunction, tubular injury, and cell death in both septic (CLP) and ischemic (I/R) murine models of acute kidney injury. ABSTRACT Objective Acute kidney injury (AKI) is a common and serious clinical condition, yet effective targeted ...

Posterolateral corner reconstruction using hamstrings grafts—A comparative biomechanical study of three techniques

open access: yesKnee Surgery, Sports Traumatology, Arthroscopy, EarlyView.
Abstract Purpose To compare three posterolateral corner (PLC) reconstruction techniques—the popliteofibular loop (PFLoop), the modified LaPrade (LP) and modified Arciero (AR) techniques—in restoring knee laxity in varus (VR), external tibial rotation (ER) and posterior tibial translation (PTT). Methods Nine cadaveric knees were subjected to 8Nm VR, 5Nm

Numerical Modeling of Nonlinear Coupling between Lines/Beams with Multiple Floating Bodies

open access: yes, 2010
Nonlinear coupling problems between the multiple bodies or between the mooring/riser and the offshore platform are incorporated in the CHARM3D-MultiBody, a fully coupled time domain analysis program for multiple bodies with moorings and risers.

Intensity Noise Dynamics in Terahertz Quantum Cascade Lasers

open access: yesLaser &Photonics Reviews, EarlyView.
Intensity‐noise dynamics in terahertz quantum cascade lasers are investigated across single‐mode, dense‐comb and harmonic‐comb regimes using graphene thermoelectric detectors. Harmonic combs show ∼10% lower relative intensity noise, while RIN scales as P0−γ$P_0^{ - \gamma }$ with γ≈1.2$\gamma \approx 1.2$, revealing a crossover from spontaneous ...

Dynamic Analysis of Electrically Assisted Turbocharger Rotor Considering Contact Effects in Nut Structures

open access: yesInternational Journal of Mechanical System Dynamics, EarlyView.
ABSTRACT The rotor system of an electrically assisted turbocharger (EAT) is composed of multiple shaft components; The nonlinear connection and contact effects make it difficult to determine the system dynamic characteristics. To improve the modeling accuracy of EAT rotor system and evaluate the influence of contact between multi‐axis components and ...

The iPP Printing Paradox: Interlayer Adhesion Through Crystallization

open access: yesPolymer Engineering &Science, EarlyView.
In fused filament fabrication of isotactic polypropylene, high molecular weight and a high print speed increase the shear during deposition. This shear promotes the formation of the ductile β‐phase at the interphase, which improves interlayer adhesion, as shown by an eightfold increase in fracture energy measured via a T‐peel test on two printed ...

Extensional Rheology and Extrusion Blow Molding of Idealized High‐Density Polyethylene/Polypropylene Blends as Model Post‐Consumer Resins

open access: yesJournal of Polymer Science, EarlyView.
Compatibilization markedly improves the top‐load compression performance and structural integrity of HDPE/PP blow‐molded bottles. Neat HDPE, PP, and HDPE/PP bottles exhibit premature neck cracking at relatively low strains, whereas the compatibilized HDPE/PP/C blend sustains substantially higher loads and greater deformation without cracking ...
