Dopant‐Tailored Matrices: A Crystal Engineering Strategy for Organic Room‐Temperature Phosphorescent Host–Guest Systems and Beyond

open access: yesAngewandte Chemie, EarlyView.
Rather than selecting dopants to match a pre‐existing host matrix, the dopant‐tailored matrix strategy involves rational engineering of host matrices around a preselected class of dopants by targeting matrix packing motifs that promote synergistic host‐dopant interactions upon doping.

A Study on Fuel Estimation Algorithms for a Geostationary Communication & Broadcasting Satellite [PDF]

open access: yesJournal of Astronomy and Space Sciences, 2000
It has been developed to calculate fuel budget for a geostationary communication and broadcasting satellite. It is quite essential that the pre-launch fuel budget estimation must account for the deterministic transfer and drift orbit maneuver ...

3D MXene Aerogel Frameworks With In Situ‐Grown BiFeO3 for Synergistically Enhanced Thermoelectric Performance

open access: yesAdvanced Electronic Materials, EarlyView.
A lightweight, 3D MXene aerogel framework integrated with bismuth ferrite was developed to efficiently harvest waste heat. By growing the oxide directly onto the porous aerogel, the composite achieves strong interfacial connections. This unique architecture simultaneously boosts electrical power generation and blocks heat flow, resulting in an ...

Orbit Determination Error Analysis for the KOMPSAT [PDF]

open access: yesJournal of Astronomy and Space Sciences, 1998
Orbit error analysis was performed for the GPS navigation solutions and ground station tracking data of the KOMPSAT (Korea Multi-Purpose SATellite), which will be launched in 1999 for cartography of Korean peninsula as main mission. A least square method

Stabilization of Ultrafast Domain Wall Motion by Edge‐Anisotropy Engineering in Ferrimagnetic Nanowires

open access: yesAdvanced Electronic Materials, EarlyView.
Localized laser annealing transforms distorted, edge‐pinned domain‐wall motion in ferrimagnetic Pt/GdFe nanowires into straight, stable, and ultrafast propagation. Experiments and micromagnetic simulations reveal an optimum anisotropy‐engineering window in which moderate edge softening suppresses pinning, whereas excessive anisotropy reduction or ...

The Selection of Altitude and Inclination for Remote Sensing Satellites [PDF]

open access: yesJournal of Astronomy and Space Sciences, 1995
The success of a satellites mission is largely depended upon the choice of an appropriate orbit. In the case of a remote sensing satellite which observes the Earth, there exits an optimum solar elevation angle depending on the mission.

Holographic Mapping of Orbital Angular Momentum using a Terahertz Diffractive Optical Neural Network

open access: yesAdvanced Intelligent Discovery, EarlyView.
A compact six‐layer diffractive optical neural network enables direct recognition and spatial mapping of terahertz (THz) orbital angular momentum (OAM) beams. Fabricated by 3D printing, the system distinguishes nine OAM modes and their superpositions with high fidelity, good efficiency, and low crosstalk, offering a scalable solution for THz ...

Overcoming the Phase Discontinuity Problem in RIS Optimization: A Robust and Scalable Phase‐Aware Deep Regression Framework via Hybrid CNN–LSTM Architecture

open access: yesAdvanced Intelligent Systems, EarlyView.
The phase discontinuity problem—where the cyclic nature of phase angles causes catastrophic errors near the ±π boundary—is a fundamental obstacle in learning‐based reconfigurable intelligent surface (RIS) optimization. A phase‐aware hybrid CNN–LSTM framework resolves this by decomposing phase predictions into sine–cosine components, mapping circular ...

Navigating Asparaginase Treatment for Patients With Acute Lymphoblastic Leukemia: US Consensus Panel Recommendations on the Role of Multidisciplinary Care

open access: yesAmerican Journal of Hematology, EarlyView.
ABSTRACT Asparaginase is a critical treatment component for patients with acute lymphoblastic leukemia/lymphoblastic lymphoma (ALL/LBL). However, the successful delivery of asparaginase‐based therapy remains challenging across care settings due to its complex administration, distinct toxicity profile, prolonged treatment duration, and the need for ...
