Machine Learning‐Driven Capillary Microfluidic Design Automation for Programmable Gradient Generation and Antimicrobial Testing

Small, EarlyView.
TCG‐CMDA, a machine learning‐guided capillary microfluidic design automation platform, enables automated design of tree‐shaped concentration gradient generators for programmable mixing of two agents. The pump‐free chip supports synchronized passive flow and programmable gradient formation, providing a practical framework for decentralized point‐of‐care

Unlocking n‐alk‐1‐ynes conformers: Quantum “trigger finger” versus “stiff joint” conformations

Smart Molecules, EarlyView.
Quantum chemical analysis reveals the unique function of n‐alk‐1‐yne terminus as a Quantum “Trigger Finger,” exhibiting two near‐isoenergetic conformers (Cs ${\mathrm{C}}_{s}$and C1 ${\mathrm{C}}_{1}$) locked by a symmetric high barrier. This contrasts with the lower asymmetric barrier of the conventional asymmetric “Stiff Joint” alkyl chain.

Luminosity Discrepancy in the Equal-Mass, Pre--Main Sequence Eclipsing Binary Par 1802: Non-Coevality or Tidal Heating?

, 2011
Parenago 1802, a member of the ~1 Myr Orion Nebula Cluster, is a double-lined, detached eclipsing binary in a 4.674 d orbit, with equal-mass components (M_2/M_1 = 0.985 \pm 0.029).

Haunting the Historiography of Slaves in South Asia from the nineteenth century to the present

Gender &History, EarlyView.
ABSTRACT Using both English and Urdu‐language records, this article traces the career of a few African and Afro‐Asian women slaves in the household‐state of Awadh during the first half of the nineteenth century. Focusing on the same records, this article compares a master‐poet's recognition of the motherhood of the African and Afro‐Asian slaves to the ...

TIC 322208686: An Eclipsing System with γ Doradus Pulsations and a Third Component on a Wider Orbit

The Astronomical Journal
TIC 322208686 is known to be a detached binary that exhibits two types of variability: pulsation and eclipse. We present the physical properties of the target star using the short-cadence TESS data from sectors 24, 57, and 58, and our echelle spectra ...

Spectroscopic Study of Long Period Eclipsing Binary 32 Cygni [PDF]

Journal of Astronomy and Space Sciences, 1992
Spectra of the ζAurigae type eclipsing binary system 32 Cygni were taken at the Asiago Observatory. Using the Gaussian fitting method we can estimate the radial velocity and equivalent widths of some metalic lines.

Turbulence in the Atmospheres of Eclipsing Binary Stars [PDF]

International Astronomical Union Colloquium, 1980
Abstract:A review of the orbits and dimensions of the ζ Aurigae systems is given, based on photometric and spectrographic observations. The Ca II K-line has been studied intensively to determine the extent and uneven structure of the chromospheres of these stars; the multiple structure of this line observed at several eclipses confirms the presence of ...
