A Novel Approach to Estimate the Transition Temperature via Dynamic Nanoindentation
Advanced Engineering Materials, EarlyView.A new dynamic nanoindentation‐based method was developed that uses the stiffness ratio as an indicator of the elastic–plastic deformation contributions at different temperatures. The approach successfully identified transition temperatures in ferritic steel and distinguished them from continuously ductile austenitic steel.

Electrodeposition in Structural Lattices of Variable Architectures
Advanced Engineering Materials, EarlyView.Electrodeposition enables geometry‐sensitive, autonomous void filling while simultaneously tuning chemical and mechanical properties. The development of approaches that can autonomously fill and heal material voids and yield composites with tailorable properties is increasingly relevant in engineering.

Spatial Frequency Modulation of Probing Signals from Phased Array Radar Systems
Известия высших учебных заведений России: РадиоэлектроникаIntroduction. Complex signals are widely used in radar location. The use of phased array antennas (PAA) offers additional opportunities for covert operation of radar systems by increasing their noise immunity and electromagnetic compatibility.

Security against probe-response attacks in collaborative intrusion detection [PDF]
Proceedings of the 2007 workshop on Large scale attack defense, 2007 Probe-response attacks are a new threat for collaborative intrusion detection systems. A probe is an attack which is deliberately crafted so that its target detects and reports it with a recognizable "fingerprint" in the report. The attacker then uses the collaborative infrastructure to learn the detector's location and defensive capabilities from this

LaserEscape: Detecting and Mitigating Optical Probing Attacks [PDF]
International Conference on Computer Aided DesignThe security of integrated circuits (ICs) can be broken by sophisticated physical attacks relying on failure analysis methods. Optical probing is one of the most prominent examples of such attacks, which can be accomplished in a matter of days, even with

Advanced Engineering Materials, EarlyView.Additively manufactured AlCrFe2Ni2 with contrasting BCC/B2‐dominant and lamellar FCC + BCC/B2 microstructures exhibits the same pressure‐induced BCC/B2 → HCP transformation. Under laser heating at high pressure, HCP is destabilized, and a cubic BCC/B2 + FCC assemblage is recovered, while the lower‐scan‐speed microstructure transforms at a lower ...

Advanced Engineering Materials, EarlyView.This study explores the influences of calendering and surface treatment during direct ink writing (DIW) of thermochromic cholesteric liquid crystal (CLC) on PET nonwovens. For the PVA‐coated nonwovens, calendering reduces pore size leading to reduced ink absorption and enhanced spreading. The NeverWet‐coated nonwovens improve thermochromic responses by

Time Sharing - A Novel Approach to Low-Latency Masking
Transactions on Cryptographic Hardware and Embedded SystemsWe present a novel approach to small area and low-latency first-order masking in hardware. The core idea is to separate the processing of shares in time in order to achieve non-completeness.
