Data‐Driven Discovery of Unconventional Antiferromagnets

Advanced Science, EarlyView.
A high‐throughput workflow that combines the physics‐informed pre‐screening, high‐throughput exchange calculations, Luttinger‐Tisza analysis and symmetry classification is established for accurate identification of unconventional antiferromagnets from the broad structural database.

Bistable Networks Enable Complex Shape Changes

Advanced Science, EarlyView.
Transition‐controlled metamaterials are networks of bistable mechanical memory that store local binary states and express them as global shape change. By decoupling low‐force programming from high‐force holding, a single lattice is reconfigured into distinct 2D profiles and 3D surfaces without continuous actuation, enabling reusable morphing materials ...

UFL1‐Mediated UFMylation of ENO1 Restrains Aerobic Glycolysis and Colorectal Cancer Progression

Advanced Science, EarlyView.
UFMylation restrains aerobic glycolysis and colorectal cancer progression by modifying the glycolytic enzyme ENO1. Pharmacological enhancement of the UFL1–ENO1 interaction by the FDA‐approved antibiotic torezolid promotes ENO1 UFMylation, suppresses tumor metabolism, and sensitizes colorectal cancer to chemotherapy, revealing an actionable metabolic ...

Method for reducing the storage overhead of the IEX scheme

网络与信息安全学报
Searchable symmetric encryption was recognized as an efficient method for searching within encrypted data. The IEX scheme was the first to achieve sublinear search complexity while supporting Boolean queries; however, it was found to incur high server ...

Analog Weight Update Rule in Ferroelectric Hafnia, Using picoJoule Programming Pulses

Advanced Electronic Materials, EarlyView.
Resistive, ferroelectric synaptic weights based on BEOL‐compatible hafnia/zirconia nanolaminates are fabricated. Lateral downscaling the devices below 10 µm2 enables 20 ns programming with electrical pulses, dissipating ≤ 3 pJ. Experimental results show that final conductance state is set by pulse amplitude, and is largely independent of the initial ...

Machine Learning‐Assisted Design and Performance Prediction of a Compact Dual‐Band Polarization‐Insensitive THz Metamaterial Absorber for Skin‐Cancer‐Related Refractive‐Index Sensing

Advanced Electronic Materials, EarlyView.
A compact QASRR‐based THz metamaterial absorber enables polarization‐insensitive dual‐band absorption and skin‐cancer‐related refractive‐index sensing through measurable resonance shifts. Field, surface‐current, and circuit analyses clarify the dual‐resonance mechanism, while StackNet‐assisted prediction accurately estimates the simulated absorption ...

Benchmarking Dynamic Searchable Symmetric Encryption with Search Pattern Hiding [PDF]

, 2017
在這個雲端計算蓬勃發展的時代，可搜尋對稱式加密 (Searchable Symmetric Encryption; SSE) 成為一個日趨重要的技術。透過這個技術，我們可以將重要資料加密後儲存在不受信任的雲端伺服器上，並且能以關鍵字進行資料檢索。遠端伺服器不會知道我們所搜尋的關鍵字，也不會知道我們所要提取的檔案內容，但是卻可以傳回正確的資料給我們。然而，一個支援SSE的資料庫仍然不夠切實，因為資料不是永遠不變動的。一般來說，我們會經常修改資料，即使該資料儲存於遠端的伺服器上 ...
