Light scattering patterns of triaxial ellipsoidal drops and their use in inferring drops’ shapes, aided by deep learning Open
Nonspherical liquid drops are commonly encountered in atmospheric optics, multiphase flows, and chemical engineering, where accurate determination of their shape and size is essential for both fundamental research and practical application…

Time-stretch multispectral LiDAR enabled by a supercontinuum laser and a single-point detector Open
Multispectral LiDAR enables the acquisition of both spatial and spectrally rich information from a target, and has potential in diverse target detection applications. However, it currently faces several limitations, including a limited num…

Increase of Curie point of BaTiO<sub>3</sub> ceramics by stoichiometry, point defects and doping processing Open
The Curie point of barium titanate (BaTiO 3 ) has been a focal point of research since the discovery of its ferroelectric properties. Exploring methods to elevate the Curie point without relying on Pb as a dopant presents fresh opportuniti…

Evidence of Yb3+ band broadening and continuous wave laser operation in bismuth modified KY1-x-yBixYby(WO4)2 mixed single crystals Open
To increase the Yb3+ optical bandwidths in highly anisotropic β:KY(WO4)2 (KYW) type laser single crystals, the simultaneous contributions of the Bi3+ 6s2 lone electron pair and Y3+/Bi3+ ionic radii mismatch is proposed. The top seeded solu…

Local most-probable routes and classical-quantum correspondence in strong-field two-dimensional tunneling ionization Open
We study ionization of atoms in strong two-dimensional (2D) laser fields with\nvarious forms, numerically and analytically. We focus on the local\nmost-probable tunneling routes (some specific electron trajectories) which are\ncorrespondin…

Sintering Behavior of BST Nanoparticles at Low Temperature and Electrical Properties of their Ceramics Open
The powders of the Ba 0.75 Sr 0.25 TiO 3 (BST) nanoparticles were directly synthesized by milling of Ba(OH) 2 ·8H 2 O, Sr(OH) 2 ·8H 2 O and Ti(BuO) 4 in ethanol at room temperature. They have homogenous grains of ~15 nm and the high sinter…

Idiopathic Male Infertility is Strongly Associated with Aberrant DNA Methylation of Imprinted Loci in Sperm: A Case-Control Study Open
Background: Male infertility is a complex disease caused by a combination of genetic, environmental, and lifestyle factors.Abnormal epigenetic programming has been proposed as a possible mechanism compromising male fertility.Recent studies…

Efficient up-conversion in Yb:Er:NaT(XO4)2 thermal nanoprobes. Imaging of their distribution in a perfused mouse Open
Yb and Er codoped NaT(XO4)2 (T = Y, La, Gd, Lu and X = Mo, W) disordered oxides show a green (Er3+ related) up-conversion (UC) efficiency comparable to that of Yb:Er:β-NaYF4 compound and unless 3 times larger UC ratiometric thermal sensiti…

Mode-locked laser operation of Indium-modified Yb:KY(WO_4)_2 single crystal Open
We report the first pulsed laser operation of an Indium-modified Yb:KY(WO4)2 crystal. Indium incorporation enlarges the broadening of the Yb3+ optical bands, reduces crystal lattice parameters and increases n(p) refractive index. A KY0.8In…
