Optoelectrical Devices for Neural Interfacing: Engineering Integration, Stability, and Multimodal Sensing

Advanced Healthcare Materials, EarlyView.
Implantable optoelectrical devices are an effective resource for the modulation and monitoring of neural activity with high spatiotemporal resolution. This review discusses current challenges faced by these devices and outlines future perspectives for the development of next‐generation neural interfaces targeting chronic, multisite, and multimodal ...

Transistorized Marx bank pulse circuit provides voltage multiplication with nanosecond rise-time [PDF]

, 1968
Base-triggered avalanche transistor circuit used in a Marx bank pulser configuration provides voltage multiplication with nanosecond rise-time. The avalanche-mode transistors replace conventional spark gaps in the Marx bank.

Rate-Dependent Avalanche Size in Athermally Sheared Amorphous Solids

, 2009
We perform an extensive numerical study of avalanche behavior in a 2D LJ glass at T=0, sheared at finite strain rates $\dot\gamma$. From the finite size analysis of stress fluctuations and of transverse diffusion we show that flip-flip correlations ...

Natural Emergencies and Some Causes of Their Occurrence: a Review [PDF]

Trends in Ecological and Indoor Environmental Engineering
In recent decades, nature has seen many anomalies with the environment, climate, and the processes taking place. This leads to a change in the temperature of the environment, the formation of meteorological processes that are not characteristic of a ...

Phonon Engineering in Ultrathin Sn Films

Advanced Materials Interfaces, EarlyView.
When embedded in multilayer structures, ultrathin Sn layers demonstrate strongly modified vibrational density of states (VDOS). This allows engineering a drastic increase of the Lamb‐Mössbauer factor fLM$f_{\text{LM}}$ and thereby of the cross‐section for coherent excitation of the ultrasharp nuclear resonance of 119Sn$^{119}{\rm Sn}$. This enables the

Quantum Decoherence of Nitrogen‐Vacancy Spin Ensembles in a Nitrogen Spin Bath in Diamond Under Dynamical Decoupling

Advanced Optical Materials, EarlyView.
Combining high‐order cluster‐correlation expansion with experiment, it is revealed that P1‐driven NV decoherence under dynamical decoupling deviates from semi‐classical scaling laws. The coherence‐time exponent depends on pulse number and bath conditions, demonstrating the necessity of a full quantum bath description.

The Dendritic magnetic avalanches in carbon-free MgB$_2$ thin films with and without a deposited Au layer

, 2005
From the magneto optics images (MOI), the dendritic magnetic avalanche is known to appear dominantly for thin films of the newly discovered MgB$_2$. To clarify the origin of this phenomenon, we studied in detail the MOI of carbon-free MgB$_2$ thin films ...

Multi‐Organelle Stress‐Induced Paraptosis by a ROS‐Amplifying Nanocatalyst for Enhanced Cancer Immunotherapy

Advanced Science, EarlyView.
The engineered TF‐Fe@LC nanoplatform programs paraptotic death via multipath ROS amplification that disrupts redox homeostasis, provoking mitochondrial dysfunction, autophagic blockade, and ER stress. This caspase‐independent process elicits robust immunogenic cell death, combining with αPD‐L1 to activate systemic CD8+ T‐cell immunity and suppress ...

La construction du risque au prisme territorial : dans l'ombre de l'archétype alpin, les avalanches oubliées de moyenne montagne

Natures Sciences Sociétés, 2017
En France, le risque d'avalanche reste associé à la haute montagne, mais semble oublié dans les espaces de moyenne montagne. À partir des exemples de l'archétype alpin et du massif vosgien, cet article discute les mécanismes sociohistoriques ayant abouti
