Kozai-driven mass loss of the circumbinary disk in D9 in orbit around the supermassive black hole Sgr A*

Astronomy & Astrophysics
Context. The supermassive black hole (Sgr A*) in the Galactic center is surrounded by the S-star cluster consisting of young stars on eccentric orbits. Recently, the an S-star binary system, called D9, was found.

Maxwell Gravitation

Philosophy of Science, 2018
This article gives an explicit presentation of Newtonian gravitation on the backdrop of Maxwell space-time, giving a sense in which acceleration is relative in gravitational theory. However, caution is needed: assessing whether this is a robust or interesting sense of the relativity of acceleration depends on some subtle technical issues and on ...

A Hybrid Bioprinting–Microfabrication Approach to Controllable Multitype Spheroid Arrays for Modeling Tumor Heterogeneity

Advanced Healthcare Materials, EarlyView.
This work introduces a “cancer‐in‐a‐well” technology that recreates tumor heterogeneity in vitro using multitype spheroid arrays. Combining bioprinting/microdispensing with microstructured culture devices, the system improves drug screening and modeling of tumor complexity.

Advances in 3D Bioprinting for Breast Cancer Modeling: Tumor Microenvironment, Metastasis, and Drug Screening

Advanced Healthcare Materials, EarlyView.
Three‐dimensional bioprinting transforms breast cancer modeling from simple constructs into spatially organized, multicellular, perfused, and patient‐derived platforms. This review shows how bioinks, cellular composition, architecture, and flow govern tumor behavior and drug response, while revealing why complexity alone is insufficient without ...

On the gravitation and convergence of industry incremental rates of return in OECD countries [PDF]

The hypotheses of sectoral incremental rates of returns gravitating around or converging towards a common value are tested on data for various OECD countries relying on an econometric method able to account for residual autocorrelation and cross-sector ...

Retrospective Analysis of Pulse Wave Flattening for G-LOC Detection Using Automatic Computer Algorithm Methods

Aerospace
The possibility of G-induced loss of consciousness (G-LOC) is a key concern when flying modern, high-performance aircraft. Currently, there are no identification methods available based on physiological data.

Comprehensive In Vitro Profiling Demonstrates Successful Immune Evasion of Bioengineered Immune‐Shielded Heart Valves

Advanced Healthcare Materials, EarlyView.
Living donor heart valves offer superior durability for pediatric patients but trigger immune rejection. Lentiviral delivery of viral immune‐evasion genes US2 and Serpin b9 into donor valve cells and valve tissue suppresses HLA expression, reduces PBMC clustering and cytotoxic killing, and induces transcriptional immune‐tolerance programs, paving the ...
