Icariin Enhances the Enzymatic Activity of N‐acetylgalactosaminidase to Augment Akkermansia Abundance in Gut Microbiota for Improved PD‐1 Blockade Efficacy in Tumor Suppression

open access: yesAdvanced Science, EarlyView.
Icariin promoted the growth of Akk by enhancing the activity of N‐acetylgalactosaminidase (Amuc_0920), which enhanced mucin utilization and provided a favorable nutrient environment for bacterial growth. This icariin‐mediated enrichment of Akk further reshaped the tumor microenvironment and promoted CD8+ T cell infiltration, ultimately synergizing with

Jerky chiral active particles

open access: yesNew Journal of Physics
We introduce jerky chiral active Brownian particles (ABP), a generalization of conventional chiral ABPs subjected to jerk, the time derivative of acceleration, and analytically derive their mean displacement and mean squared displacement.

Gravitation in the fractal D=2 inertial universe: New phenomenology in spiral discs and a theoretical basis for MOND

open access: yes, 2003
An interpretation of Mach's Principle led us to consider if it was possible to have a globally inertial universe that was irreducibly associated with a non-trivial global matter distribution, Roscoe (GRG,2002,34,5,577-602, astro-ph/0107397).

Tumor‐Derived Alpha‐1 Antitrypsin Promotes Liver Metastasis of Colorectal Cancer Through the Neutrophil Extracellular Traps–CCDC25 Pathway

open access: yesAdvanced Science, EarlyView.
ABSTRACT Liver metastasis is a leading cause of mortality in colorectal cancer (CRC), where the inflammatory tumor microenvironment, specifically neutrophil infiltration, significantly promotes metastatic colonization. This study reveals a pro‐metastatic role for alpha‐1 antitrypsin (A1AT) in CRC liver metastasis via a dual mechanism involving ...

On the Determination and Use of Principal Lines

open access: yesEngineering Transactions, 1977
Assuming plane strain for Huber-Mises yield condition (for a Coulomb-Tresca one, both plane strain and stress are admitted) of incompressible homogeneous isotropic ideal plastic medium, basic relation of principal lines (of curvatures and their ...

Spirality: A Novel Way to Measure Spiral Arm Pitch Angle

open access: yes, 2016
We present the MATLAB code Spirality, a novel method for measuring spiral arm pitch angles by fitting galaxy images to spiral templates of known pitch. Computation time is typically on the order of 2 minutes per galaxy, assuming at least 8 GB of working ...

Spintronic Bayesian Hardware Driven by Stochastic Magnetic Domain Wall Dynamics

open access: yesAdvanced Science, EarlyView.
Magnetic Probabilistic Computing (MPC) utilizes intrinsic stochastic dynamics in domain walls to establish a hardware foundation for uncertainty‐aware artificial intelligence. Thermally driven domain‐wall fluctuations, voltage‐controlled magnetic anisotropy, and TMR readout enable fully electrical, tunable probabilistic inference.

Hydrodynamical Simulations of the Barred Spiral Galaxy NGC 1097

open access: yes, 2013
NGC 1097 is a nearby barred spiral galaxy believed to be interacting with the elliptical galaxy NGC 1097A located to its northwest. It hosts a Seyfert 1 nucleus surrounded by a circumnuclear starburst ring.
