Measurements of Neutron Polarizations for Deuteron Energies from 0.87 to 5.00 MeV

open access: yes, 1972
Neutron time-of-flight techniques have been used to measure [Formula: see text] polarization angular distributions for several deuteron energies from 0.87 to 5.00 MeV. Liquid helium served as the polarized neutron analyzer.

Critical Coupling in Semi‐Trasparent Fano Resonators for Photothermal Converters

open access: yesAdvanced Functional Materials, EarlyView.
An ultrathin metal–insulator multilayer architecture is engineered to exploit Fano‐resonant critical coupling, completely suppressing optical reflectance while achieving a balanced 50:50 trade‐off between absorbance and transmittance. Upon laser excitation at resonance, the metamaterial generates intense localized heat (ΔT≈550∘C$\Delta T {\approx }550^\

Dynamic Recrystallization Behavior of AISI 420 Stainless Steel under Hot Compression

open access: yesHigh Temperature Materials and Processes, 2015
Hot deformation behavior of AISI 420 stainless steel was studied under hot compression tests in the temperature range of 950 to 1150 °C and strain rates of 0.01 s−1 and 0.1 s−1.

Exceptional Electro‐Optic Coefficient Unlocked via Polarization Swaying in KNbO3 Thin Films

open access: yesAdvanced Functional Materials, EarlyView.
We present the largest reported electro‐optic response in any material to date, guided by a new design principle that exploits ultralow coercive field polarization swaying enabled by low‐symmetry ferroelectric phases in monoclinic KNbO3 thin films for energy‐efficient classical and quantum photonic integrated circuits. ABSTRACT The electro‐optic effect

Efficient Magnetization Switching Driven by Orbital Torque in Light 3d Transition‐Metal Nitrides

open access: yesAdvanced Functional Materials, EarlyView.
Efficient magnetization switching is demonstrated through orbital torque generated from light 3d transition‐metal nitride. Transition‐metal nitrides are established as effective sources of orbital angular momentum for current‐induced switching, highlighting their potential for low‐power next‐generation orbitronic devices beyond conventional heavy‐metal‐

DEM-FEM Coupling Simulation of Residual Stress Improvement for Q235B Welded Joint via Shot Peening

open access: yesMetals
To overcome the welding-induced residual tensile stress of Q235B welded joints, a sequential thermal-mechanical welding and DEM-FEM dynamic shot peening coupled model is established.

(A) Active circumferential stress (σθ)-strain (εθ) relationship of middle cerebral arteries isolated from CON, SUS, and S+D rats.

open access: yes, 2014
Both σθ and εθ are calculated at the internal radius. The relationships calculated from the data of the first and second runs are depicted by curves drawn in thick lines with filled symbols and in dashed lines with open symbols, respectively.

Asymptotic behavior of general M-estimates for regression and scale with random carriers [PDF]

open access: yes, 2022
Let (xini, y i be a sequence of independent identically distributed random variables, where x i ∃R pand y i ∃R, and let θ∃R pbe an unknown vector such that y i =x′ i θ+u i (*), where u i is independent of x i and has distribution function F(u/σ), where σ>
