Synergistic Bi–Te Antisite Defects and Crystalline‐Amorphous Hybrid Structure Enable Record‐High Thermoelectric Performance in Flexible Bi2Te2.7Se0.3 Films

open access: yesAdvanced Energy Materials, EarlyView.
Flexible n‐type Bi2Te3 thin films require improved room‐temperature figure of merit (ZT) and mechanical stability. We show that synergistic Bi–Te antisite tuning and crystalline–amorphous hybridization optimizes carrier concentration, mobility, and phonon scattering.

Gauge/gravity correspondence in accelerating universe [PDF]

open access: yes, 2002
We discuss time-dependent backgrounds of type IIB supergravity realizing gravitation duals of gauge theories formulated in de Sitter space-time as a tool of embedding de Sitter in a supergravity. We show that only the gravitational duals to non-conformal

ارزیابی الگوریتم SPA و امکان‌سنجی استفاده از برو‌نداد مدل MM5 برای تخمین داده‌های مفقود ناشی از ابر‌ناکی در تصاویرLST مودیس [PDF]

open access: yesجغرافیا و مخاطرات محیطی, 2019
روش‌های اندکی به امکان‌سنجی استفاده از برونداد مدل‌های پیش‌بینی عددی در تخمین مقادیر از دست‌رفته تصاویر سنجش‌ازدور پرداخته‌اند. بدین منظور در تحقیق حاضر علاوه بر ارزیابی الگوریتم SPA در بازسازی تصاویر، امکان‌ استفاده از برونداد مدل پیش‌بینی عددی MM5 در ...

Calibration‐Free Electromyography Motor Intent Decoding Using Large‐Scale Supervised Pretraining

open access: yesAdvanced Intelligent Systems, EarlyView.
Calibration‐free electromyography motor intent decoding is enabled through large‐scale supervised pretraining across heterogeneous datasets. A Spatially Aware Feature‐learning Transformer processes variable channel counts and electrode geometries, allowing transfer across users and recording setups. On a held‐out benchmark, fine‐tuned cross‐user models

Hardware‐Based On‐Chip Learning Using a Ferroelectric AND‐Type Array With Random Synaptic Weights

open access: yesAdvanced Intelligent Systems, EarlyView.
This work demonstrates an energy‐efficient on‐chip learning system using an Metal‐Ferroelectric‐Insulator‐Semiconductor FeAND synaptic array. By employing a feedback alignment scheme with a separate backward array using fixed random weights, the system overcomes directional limitations of AND‐type arrays and achieves robust, low‐power learning suitable

Expanded application to plant reproductive tissues of a branched DNA probe‐based in situ hybridization method

open access: yesApplications in Plant Sciences, EarlyView.
Abstract Premise Detecting clear tissue‐ and organ‐specific patterns of gene expression is key to understanding the genetic mechanisms that control plant development. In situ hybridization (ISH) of mRNA is one of the most precise, yet most challenging approaches to gene expression assays.

A mosaic of microclimates: biodiversity outcomes and wildlife habitat potential in large‐scale solar facilities

open access: yesBiological Reviews, EarlyView.
ABSTRACT The rapid global expansion of photovoltaic (PV) solar facilities, now comprising nearly 80% of the recent and projected growth of renewable electricity, represents one of the most significant land‐use changes of the 21st century. While PV facilities are critical for decarbonising energy systems, their large spatial footprint and infrastructure

Re-Conceptualizing the Economic Incorporation of Immigrants: A Comparison of the Mexican and Vietnamese [PDF]

open access: yes, 2010
Using data from the 2000 5 per cent Integrated Public Use Microdata Series, this article advocates three shifts in our theoretical and empirical approaches to understanding immigrant economic incorporation.
