Locking-Enabled Security Analysis of Cryptographic Circuits

open access: yesCryptography
Hardware implementations of cryptographic primitives require protection against physical attacks and supply chain threats. This raises the question of secure composability of different attack countermeasures, i.e., whether protecting a circuit against ...

Robust High-Dynamic-Range Vector Magnetometry via Nitrogen-Vacancy Centers in Diamond

open access: yes, 2018
We demonstrate a robust, scale-factor-free vector magnetometer, which uses a closed-loop frequency-locking scheme to simultaneously track Zeeman-split resonance pairs of nitrogen-vacancy (NV) centers in diamond.

Surgical fixation by mesh plate and intraoperative safe techniques for the manubrium sterni

open access: yesTrauma Case Reports, 2021
Plate osteosynthesis for oblique fracture of the manubrium sterni is quite rare. We present a case of a 37-year-old man with oblique fracture of the manubrium sterni caused by a traumatic injury.

Infrared Nanocrystals for Space Application: Hardness to Irradiations

open access: yesAdvanced Functional Materials, EarlyView.
This article investigates infrared HgTe nanocrystals under X‐ray and ion irradiation, revealing remarkable radiation hardness. It uncovers distinct degradation mechanisms and shows that the nanomaterial outperforms integrated electronics. The results position colloidal nanocrystals as promising candidates for resilient space and harsh‐environment ...

Reawakening of large earthquakes in south central Chile: The 2016 Mw 7.6 Chiloé event

open access: yesGeophysical Research Letters, 2017
On 25 December 2016, the Mw 7.6 Chiloé earthquake broke a plate boundary asperity in south central Chile near the center of the rupture zone of the Mw 9.5 Valdivia earthquake of 1960. To gain insight on decadal‐scale deformation trends and their relation

Entrainment of randomly coupled oscillator networks by a pacemaker [PDF]

open access: yes, 2004
Entrainment by a pacemaker, representing an element with a higher frequency, is numerically investigated for several classes of random networks which consist of identical phase oscillators.

Digital Actuation Control of Soft Robotic Origami With Self‐Folding Liquid Crystal Elastomer Hinges

open access: yesAdvanced Functional Materials, EarlyView.
Self‐folding soft‐rigid hybrid robotic origami is enabled by liquid crystal elastomer actuators with embedded Joule heating and closed‐loop digital control. Digitally addressable hinges provide reversible and programmable transitions between distinct folded states while maintaining actuation performance at high cycle counts (over 1500).
