Photonic‐Enabled Energy‐Efficient Transparent Neuromorphic Computing Devices: A Review

Advanced Science, EarlyView.
Transparent photonic neuromorphic computing devices merge optics and brain‐inspired computing to overcome von Neumann bottlenecks with ultrafast, low‐energy processing. By exploiting transparent oxides, 2D materials, phase‐change materials, and hybrid heterostructures, these platforms enable photonic synapses, memory, and logic for see‐through edge ...

Particle Energization at a High Mach Number Perpendicular Shock: 1D Particle-in-cell Simulations

The Astrophysical Journal, 2023
In this paper, we use a 1D particle-in-cell simulation code to study particle preaccelerations at a high Mach number perpendicular shock. Our simulation results show that almost all of the injected particles can be reflected at the shock front, and then ...

Polymer‐Based Multiparameter Sensing Integrated Photonic Chip for Health Monitoring

Advanced Science, EarlyView.
A monolithic integrated photonic chip simultaneously measures blood glucose, pressure, temperature, ECG, and sweat glucose. Combining multiple Bragg grating sensors, Mach–Zehnder modulators, and an on–‐chip demodulation unit, this compact chip (1 cm × 0.5 cm) offers robust multiparameter detection.

Scattering of Ions at a Rippled Shock

The Astrophysical Journal, 2023
In a collisionless shock the energy of the directed flow is converted to heating and acceleration of charged particles, and to magnetic compression. In low-Mach number shocks the downstream ion distribution is made of directly transmitted ions. In higher-

Effects of Periodic Incoming Wakes on the Aerodynamics of a High-Speed Low-Pressure Turbine Cascade

International Journal of Turbomachinery, Propulsion and Power, 2023
The influence of unsteady wakes incoming from the upstream stages is of high relevance in modern high-speed, low-pressure turbines (LPT) operating at transonic exit Mach numbers and low Reynolds numbers for their potential to trigger transition and ...

Matrix Stiffness Induces Endothelial Network Senescence

Advanced Science, EarlyView.
Using a 3D human in vitro model that decouples mechanical stress from inflammatory or biochemical signals, matrix stiffening induces a senescence phenotype in endothelial networks. This mechano‐induced senescence activates Notch signaling, and pharmacologic Notch inhibition attenuates this stiffness‐induced senescence.

Numerical Investigation on Effect of Divergent Angle in Convergent-Divergent Rocket Engine Nozzle

Chemical Engineering Transactions, 2018
In rocket, a nozzle is used to control mass flow rate, velocity distribution and pressure of the exhaust gas that emerges out from the combustion chamber. The nozzle is used to alchemize the chemical and thermal energy generated in the combustion chamber

Solar wind magnetosonic mach number as a control variable for energy dissipation during magnetic storms

Frontiers in Astronomy and Space Sciences, 2022
During the main phase of many magnetic storms the solar wind Mach number is low and IMF magnitude is large. Under these conditions, the ionospheric potential saturates, and it becomes relatively insensitive to further increases in the IMF magnitude.

Discovering Early‐Stage Gas Generation Kinetics Enables Thermal Runaway Early Warning in Lithium‐Ion Batteries

Advanced Science, EarlyView.
Operando gas diagnostics reveal a previously unrecognized chemical activation (CA) stage during thermal runaway in lithium‐ion batteries. A physics‐informed gas generation kinetics network (GGKNet) is developed to reconstruct reaction pathways and physical models automatically.

Low Mach number limit for the quantum hydrodynamics system [PDF]

Research in the Mathematical Sciences, 2016
In this paper we deal with the low Mach number limit for the system of quantum-hydrodynamics, far from the vortex nucleation regime. More precisely, in the framework of a periodic domain and ill-prepared initial data we prove strong convergence of the solutions towards regular solutions of the incompressible Euler system.
