MASS TRANSFER IN ECLIPSING BINARY STARS

open access: yesOdessa Astronomical Publications, 2017
Analysis of the properties of the eclipsing binary stars shows, that the stream-like mechanism of the mass transfer switches on at a contact evolutionary stage, preceding to a stage of binaries with a subgiant.

Microgels Enable iPSCs to Assemble, Expand, and Differentiate Into Organoids—From Sizable to High‐Throughput

open access: yesAdvanced Materials, EarlyView.
A chemically defined PEG‐based microgel platform enables scalable, reproducible production of three‐dimensional microgel‐iPSC constructs in multiple sizes. The system is compatible with high‐throughput automation and supports human iPSC expansion and differentiation within a single construct, including directed differentiation into cardiac organoids ...

Phase-locked polarization by photospheric reflection in the semidetached eclipsing binary μ1 Sco [PDF]

open access: yes, 2020
We report the detection of phase-locked polarization in the bright (mV = 2.98−3.24) semidetached eclipsing binary μ1 Sco (HD 151890). The phenomenon was observed in multiple photometric bands using two different HIPPI-class (HIgh Precision Polarimetric ...

Tamper‐Responsive Physical Unclonable Functions via Graphene‐Interlayered Block Copolymer Random Structures

open access: yesAdvanced Materials, EarlyView.
Self‐invalidating multilayer physical unclonable functions (PUFs) integrate fingerprint‐like metal nanopattern bilayers from block copolymer templates with highly reactive reduced graphene oxide (rGO) interlayers. This tamper‐responsive architecture blocks all unauthorized physical and chemical replication attempts while autonomously deactivating ...

The Triple System V1371 Tau: An Eclipsing Binary with an Outer Be Star

open access: yesThe Astrophysical Journal
Although triple systems are common, their orbital dynamics and stellar evolution remain poorly understood. We investigated the V1371 Tau system using TESS photometry, multiepoch spectroscopy, and recent interferometric data, confirming it as a rare ...

Radial velocity and light curves analysis of the eclipsing binary NN Vir

open access: yesOdessa Astronomical Publications, 2017
The eclipsing binary NN Vir is a short period system showing an EW-type light curve. Photometric Observations of NN Vir were done by Gomez-Ferrellad & Garcia-Melendo (1997) at Esteve Duran Observatory.

Thermoplastic Dielectric Coatings for Flexible Electrodynamic Dust Shields: Structural and Functional Performance

open access: yesAdvanced Materials Interfaces, EarlyView.
Thermoplastic attachment is introduced as a scalable surface coating strategy to improve the durability and dielectric reliability of flexible electrodynamic dust shields. By embedding chemically modified reduced graphene oxide (CMrGO) electrodes within thermoplastic laminates, mechanical degradation, abrasion damage, and vacuum‐induced electrical ...

ABOUT 21st RUN OF WET: PG 1336-018

open access: yesOdessa Astronomical Publications, 2017
We brie communicate about 21st run of the Whole Earth Telescope (WET) in April 2001, where the eclipsing short period binary sdB system PG 1336-018 was the primary target.

Hierarchical Flux‐Protection Engineering Stabilizes Oxidation‐Prone Metabolic Nodes for High‐Level Curcumin Biosynthesis

open access: yesAdvanced Science, EarlyView.
Flux‐protection engineering stabilizes an oxidation‐prone L‐DOPA node in engineered E. coli by combining acid‐adapted chassis evolution, respiratory‐chain modulation, enzyme‐level flux matching, and pH–DO control. Carbon is redirected from oxidative browning to productive biosynthesis, enabling 1075.2 mg/L curcumin and demonstrating transferability to ...
