Generation and control of circular Airy solitons in fractional nonlinear optical systems under different modes.

In this paper, the dynamics of the circular Airy beam (CAB) in the spatial fractional nonlinear Schrödinger equation (FNLSE) optical system are investigated. The propagation characteristics of CABs modulated by the quadratic phase modulation (QPM) in a Kerr (cubic) nonlinear medium under power function diffractive modulation modes and parabolic potentials are numerically simulated by using a step-by-step Fourier method. Specifically, the threshold for CABs to form solitons in the Kerr medium is controlled by the Lévy index and the QPM coefficient.

Compact advanced pure tilt actuator for testing tilt-to-length coupling in space-based gravitational wave detection.

Tilt-to-length (TTL) coupling, caused by the jitter of test masses or satellites, is a major noise source in space-based gravitational wave detection. Calibrating and suppressing TTL coupling noise at the sub-nanometer level is essential. A key challenge in current ground-based TTL coupling testing is the residual translational movement of the tilt actuator.

Mapping of the T Cell Landscape of Biliary Tract Cancer Unravels Anatomical Subtype-Specific Heterogeneity.

Biliary tract cancer (BTC), encompassing diseases such as intrahepatic (ICC), extrahepatic cholangiocarcinoma (ECC), and gallbladder cancer (GBC), is not only on the rise but also poses a significant and urgent health threat due to its high malignancy. Genomic differences point to the possibility that these subtypes represent distinct diseases. Elucidation of the specific distribution of T cell subsets, critical to cancer immunity, across these diseases could provide better insights into the unique biology of BTC subtypes and help identify potential precision medicine strategies.

Simultaneous generation of hydroxyl and hydrogen radicals from H/OH pairs caused by water-solid contact electrification.

Water-solid contact electrification is a common physical phenomenon involving interfacial electron and ion transfer, recently discovered to trigger unique redox reactions. Here, we demonstrate the generation of both hydroxyl and hydrogen radicals when water contacts SiO. The coexistence of hydroxyl and hydrogen radicals is confirmed by simultaneous nitrate reduction and nitrite oxidation during the contact.

Suppressing Oxygen Adsorption on Bulk Arsenic and 2D Arsenic Nanoflake Surfaces: The Role of Sb Doping.

The susceptibility of bulk and exfoliated nanolayered arsenic to oxidation has been a significant obstacle limiting their widespread application and safe disposal. Here we report a controllable antimony-doped (Sb-doped) method via chemical vapor transport (CVT) with SnI as a transport agent to prepare the bulk arsenic. After 96 h of exposure to air, the oxygen content on the surface of Sb-doped arsenic with SnI is 67% lower compared to the undoped arsenic with SnI, and 89% lower than the control group (undoped arsenic without SnI).
