Electronic Structure Reorganization in MPS3 via d‐Shell‐Selective Alkali Metal Doping

open access: yesAdvanced Science, EarlyView.
Alkali metal doping of layered MPS3 antiferromagnets reveals d‐shell‐selective responses. While MnPS3 resists charge transfer due to its half‐filled 3d5 shell, FePS3 and NiPS3 behave similarly to CoPS3 by accommodating extra d‐electrons. Yet only CoPS3, with its least stable d‐shell, undergoes pronounced band restructuring and a semiconducting‐to ...

A mathematical model of an active control landing gear for load control during impact and roll-out [PDF]

open access: yes
A mathematical model of an active control landing gear (ACOLAG) was developed and programmed for operation on a digital computer. The mathematical model includes theoretical subsonic aerodynamics; first-mode wing bending and torsional characteristics ...

Heuristically Adaptive Diffusion‐Model Evolutionary Strategy

open access: yesAdvanced Science, EarlyView.
Building on the mathematical equivalence between diffusion models and evolutionary algorithms, researchers demonstrate unprecedented control over evolutionary optimization through conditional diffusion. By training diffusion models to associate parameters with specific traits, they can guide evolution toward solutions exhibiting desired behaviors ...

Semi-analytical guidance algorithm for autonomous close approach to non-cooperative low-gravity targets [PDF]

open access: yes, 2014
An adaptive guidance algorithm for close approach to and precision landing on uncooperative low-gravity objects (e.g. asteroids) is proposed. The trajectory, updated by means of a minimum fuel optimal control problem solving, is expressed in a polynomial

Super‐Enhancer‐Driven SOX4/SMAD3 Mediate Membrane Remodeling by Regulating Phospholipid Metabolism to Accelerate Leukemia Progression

open access: yesAdvanced Science, EarlyView.
Chronic myeloid leukemia blast phase (CML‐BP) poses a severe therapeutic challenge. This study reveals that the super‐enhancer‐driven transcription factors SOX4 and SMAD3 form a cooperative axis critical for disease progression. They co‐activate the oncogenic kinase AXL and promote phospholipid remodeling via LPCAT1 to facilitate its signaling ...

Land encroachment: India's disappearing common lands. [PDF]

open access: yes, 2004
Opportunistic land encroachment, resulting from costly and incomplete enforcement of common land boundaries, is a problem in many less-developed countries. A multi-period model of such encroachment is presented in this paper. The model accounts explicitly for the cumulative effects of non-compliance of regulations designed to protect a finite, non ...
