A Reproducible SEM Surface Imaging Protocol for Monitoring Microstructural Changes During Gas–Rock Interactions

open access: yesGreenhouse Gases: Science and Technology, EarlyView.
ABSTRACT Reliable characterization of mineralogical and textural changes in rock samples is essential for understanding fluid–rock interactions, particularly in experimental studies simulating subsurface conditions. This study presents a reproducible protocol for scanning electron microscopy (SEM) analysis of rock surfaces before and after exposure to ...

Arithmetic Sequences without Arithmetic Operations

open access: yes
The generation of arithmetic sequences involves arithmetic operations. However, is it possible to generate such sequences without being subject to any arithmetic or related operations, all by just hand? The answer may be negative, as the very rule defining these sequences itself relies on arithmetic operations.

Operating Capacity, Pricing and Supply Elasticity in Container Shipping Markets

open access: yesInternational Journal of Finance &Economics, EarlyView.
ABSTRACT We investigate the channels through which changes in operating capacity influence freight rates in the container shipping market using a novel dataset to create an operating capacity index at the shipping‐route level. Our analysis reveals that when supply elasticity is low, an increase in operating capacity tends to drive freight rates upward,

Implementation of arithmetic operations with complex numbers on FPGA

open access: yesТехнологія та конструювання в електронній апаратурі, 2008
Hardware implementations of arithmetic operations with complex numbers for signed integers are proposed. Generators of sinusoidal and cosine signals of different frequencies were used to construct the test bench. Physical verification of the operation of

Field‐free programmable bipolar magnetic heterostructures for neuromorphic computing

open access: yesInfoMat, EarlyView.
Neuromorphic computing mimics the brain's efficiency, yet typical memristors lack biological synapses' dual signal control. We introduce a magnetic memristor enabling bidirectional, multi‐state modulation without external fields, validated in image feature extraction and neural clustering.

New Approach Methodologies (NAMs) in Alternative Methods: A Comparative Cytotoxicity Analysis of Nanostructured Hydroxyapatite in Adipose Stem Cells Spheroids

open access: yesJournal of Applied Toxicology, EarlyView.
ABSTRACT Toxicological assessment is essential in NP approval for health and medical applications. Although 2D cell culture has been widely used, 3D models, especially spheroids, provide better predictive value for toxicological risk assessments since they replicate complex cellular interactions more accurately.

A novel knee implant for total knee arthroplasty meets expectations at 10 years. First long‐term follow‐up report of clinical outcomes and survivorship

open access: yesKnee Surgery, Sports Traumatology, Arthroscopy, EarlyView.
Abstract Purpose Achieving a “forgotten knee” after total knee arthroplasty (TKA) remains a primary goal in modern knee replacement surgery. Anatomic implant designs aim to replicate native knee anatomy and kinematics, potentially improving patient satisfaction and functional outcomes.

Unrestricted kinematic alignment in varus total knee arthroplasty outperforms mechanical alignment in CPAK I phenotype, but yields comparable outcomes in CPAK IV: A retrospective analysis from the FP‐UCBM Knee Study Group

open access: yesKnee Surgery, Sports Traumatology, Arthroscopy, EarlyView.
Abstract Purpose To compare clinical outcomes in varus‐aligned patients undergoing cruciate‐retaining total knee arthroplasty (TKA) with mechanical alignment (MA) versus unrestricted kinematic alignment (KA). The hypothesis was that KA would yield superior outcomes, and that preserving joint line obliquity—regardless of alignment technique—would be ...

Medial‐pivot design total knee arthroplasty provides higher post‐operative patient satisfaction than posterior‐stabilized design under mechanical alignment

open access: yesKnee Surgery, Sports Traumatology, Arthroscopy, EarlyView.
Abstract Purpose Numerous studies have compared post‐operative patient‐reported outcome measures (PROMs) between medial‐pivot design total knee arthroplasty (MP‐TKA) and posterior‐stabilized design TKA (PS‐TKA); however, whether MP‐TKA demonstrates superior outcomes remains controversial.
