MRI Proton Density Fat Fraction as a Biomarker of Marrow Recovery Following Organ‐Sparing Total Marrow Irradiation in Sickle Cell Disease

open access: yesJournal of Magnetic Resonance Imaging, EarlyView.
ABSTRACT Background Noninvasive quantitative assessment of marrow recovery after curative therapies such as total marrow irradiation (TMI) and bone marrow transplantation (BMT) remain poorly defined, particularly in sickle cell disease (SCD). Purpose To evaluate MRI‐derived proton density fat fraction (PDFF) as a biomarker of marrow recovery following ...

Interpolative BTC Image Coding with Vector Quantization

open access: yes, 1993
We suggest two interpolative BTC image coding schemes with vector quantization and median filters as the interpolator. The first scheme is based on quincunx subsampling and the second one on every-other-row-and-every-other-column subsampling. It is shown

In Situ Atmospheric Plasma Treatment Enables First‐Layer Adhesion of PEEK on Borosilicate Glass for FDM‐Printed Non‐Assembly Mechanisms

open access: yesPolymer Engineering &Science, EarlyView.
A printhead‐mounted plasma nozzle activates the PEEK melt and the borosilicate print‐bed at the instant of contact. Only this simultaneous in‐situ activation of both interfaces yields reliable first‐layer adhesion (0.22 MPa). ABSTRACT Fused deposition modeling of poly‐ether‐ether‐ketone (PEEK) requires a high‐temperature build plate, yet PEEK does not ...

Application of synthesized metal-trimesic acid frameworks for the remediation of a multi-metal polluted soil and investigation of quinoa responses.

open access: yesPLoS ONE
Metal-organic frameworks (MOFs) are structures with high surface area that can be used to remove heavy metals (HMs) efficiently from the environment.

Preserving Hierarchical Integrity During Primary Structure Modification of Spherulitic MOFs

open access: yesSmall, EarlyView.
A MOF‐74‐type zinc framework self‐organizes into well‐defined spherulitic superstructures while allowing precise covalent post‐synthetic modification (PSM) of the linkers. A built‐in tetrazine enables fast inverse electron‐demand Diels–Alder (iEDDA) functionalization to uniformly install primary amines.

Metal‐Organic Framework‐Templated Deconstruction‐Reconstruction Enables One‐Dimensional to Two‐Dimensional Self‐Assembly of Transition Metal Phosphates for High‐Performance Ammonia Sensing

open access: yesSmall, EarlyView.
One‐dimensional nickel phosphate nanofibres are transformed into two‐dimensional quasi‐nanosheets through a metal‐organic framework‐templated deconstruction‐reconstruction strategy. The hierarchical nanofibre‐assembled architecture provides rich mesoporosity, accessible adsorption sites, and rapid ammonia diffusion, enabling high‐performance QCM ...

Fusion Energy and Tritium Fuel Cycle: Hydrogen Isotope Separation Technologies and Sorbent Materials

open access: yesSmall Methods, EarlyView.
This review surveys sorbent‐based materials for hydrogen isotope separation, a key challenge in fusion fuel processing. Different types of adsorbents are compared in terms of selectivity, kinetics, and operational practicality. Limitations of cryogenic operation and tritium compatibility are highlighted, providing guidance toward efficient, low tritium

Movement and Space Use Patterns of the Beale's Eyed Turtle (Sacalia bealei) Suggest Sensitivity to Environmental Changes and Poaching 比氏眼斑龟 (Sacalia bealei) 的活动与空间利用模式揭示其对环境变化及盗猎的敏感性

open access: yesWildlife Letters, EarlyView.
Using radiotelemetry, we found that the movement and home range of the endangered Sacalia bealei varied significantly across reproductive classes and seasons, with males exhibiting greater movement than females during wet and mating seasons. The species exhibits strong aquatic dependence, favoring deep pools interspaced among riffle‐pool sequences ...

Tax Planning Under Pressure: The Impact of Carbon Emissions Management Post‐Paris Agreement

open access: yesAccounting &Finance, EarlyView.
ABSTRACT We examine how the Paris Agreement affects corporate tax planning across a global data set. We find that emissions‐reducing firms are associated with higher levels of tax planning than nonemissions‐reducing firms. The effect is stronger for firms facing tighter cost pass‐through constraints, such as operating in more competitive markets, with ...

Developing Predictive and Explainable Models for Cryptocurrency Delistings: A Case Study of Binance Exchange

open access: yesAsia-Pacific Journal of Financial Studies, EarlyView.
Abstract This study develops an explainable machine learning model to predict cryptocurrency delistings using Binance data. It combines quantitative indicators (price, volume) with qualitative data from real‐time news and Reddit. Latent Dirichlet Allocation (LDA) is used to extract topic trends and community reactions, which are transformed into time ...
