Ultra Short Pulse Laser Welding of Glass to Metal in the Low Fluence Regime
Ultrashortpulse laser welding enables precise joining of glass and metal with minimal thermal damage. We introduce the TwoThresholds Criteria to identify suitable laser parameters by combining the nonlinearabsorption threshold in glass with the metalmodification fluence threshold.

Sliding Mode Control in Aerospace Applications: A Survey
ABSTRACT Sliding mode control (SMC) enjoys robustness to matched and unmatched (in the case of minimum phase input‐output dynamics) bounded perturbations, and finite time convergence. Second‐order and higher‐order sliding mode control systems (2‐SMC/HOSMC) retain all the advantages of sliding mode control, but in addition can be applied to systems of ...

Laser‐Direct Printed 2D Material‐Based Heterostructure for the Fabrication of Electronic Devices
The Digital Laser‐Induced Forward Transfer (LIFT) approach is employed to pattern and stack 2D materials with micrometer‐scale precision. PdSe2 and MoSe2 are assembled into vertical p–n junctions, with graphene serving as a transparent electrode. The resulting laser‐transferred heterostructures exhibit high material quality and stable rectifying ...

A New Generalized Discontinuous-PWM Strategy for Active Power Filters
Classical discontinuous pulse width modulations (DPWM's) may not be efficiently applied in active power filters, because it is hard to predict the peak values of the inverter current, and consequently it is difficult to calculate the position of the ...

Noise‐induced reduction and early recovery of superior paraolivary nucleus sound‐offset responses
Abstract figure legend Acoustic over‐exposure transiently disrupts auditory temporal processing in mouse superior paraolivary nucleus neurons. In control conditions, neurons exhibit robust sound‐offset (OFF) responses, which are abolished immediately following noise trauma, indicating impaired temporal encoding.

Abstract Background Atrial fibrillation (AF) poses significant challenges for coronary CT angiography (CCTA) due to R‐R interval variability, often necessitating high radiation dose protocols. Absolute phase gating, which uses fixed millisecond delays rather than percentage‐based cardiac cycle timing, may optimize image quality while reducing radiation

Low‐Temperature Initiation Enhances HCN and NH3 Formation From Methane and NO Over Pt/Al2O3
Hydrogen cyanide (HCN) was formed from CH4 and NO over Pt/Al2O3 at low temperatures. Increasing NO concentration and optimizing reaction‐start conditions significantly enhanced HCN yield. In situ FTIR and DXAFS measurements revealed that dynamically balancing Pt‑CO and Pt‑CN surface species, particularly their desorption under temperature‑swing ...
