Stretchable Microelectrode Arrays for Electro‐Mechanical Probing of Brain Spheroids

open access: yesAdvanced Healthcare Materials, EarlyView.
A multimodal device featuring kirigami‐patterned stretchable microelectrode arrays enables concurrent mechanical actuation and electrophysiological recording of brain spheroids. The platform supports multiple loading regimes and reveals mechanically induced modulation of spontaneous network activity in 3D neural tissue models.

Computational starspot photometry of contact binary stars

open access: yes, 2007
Starspots are not well understood for contact binary star systems. The following properties of spots were systematically investigated: temperature, radius, colatitude, and longitude. Spots were modeled on an AE Phe like contact binary system.

A Method of Rapidly Deriving Late-type Contact Binary Parameters and Its Application in the Catalina Sky Survey

open access: yesThe Astrophysical Journal Supplement Series
With the continuous development of large optical surveys, a large number of light curves of late-type contact binary systems (CBs) have been released.

Thermal‐Driven Diode Polarity Switching From Competing Helical Superconducting States in WTe2/α‐Fe2O3 Heterostructures

open access: yesAdvanced Materials, EarlyView.
A Nb‐proximitized Josephson junction based on a WTe2/α‐Fe2O3 heterostructure exhibits a robust superconducting diode effect with programmable polarity. The diode direction can be trained by magnetic fields and switched by temperature cycling, revealing tunable finite‐momentum pairing states and competing superconducting states in symmetry‐broken ...

Endogenous semiparametric binary choice models with heteroscedasticity [PDF]

open access: yes
In this paper we consider endogenous regressors in the binary choice model under a weak median exclusion restriction, but without further specification of the distribution of the unobserved random components.

CN Trianguli: A W-type Contact Binary Exhibiting A-type Light Curve via Starspot-induced Dimming

open access: yesThe Astrophysical Journal
We present comprehensive photometric observations and analysis of the totally eclipsing binary CN Tri. The photometric solutions suggest it as an extremely low mass ratio contact binary system with q ∼ 0.08.

Thermodynamic Limits to Molecular Doping in Conjugated Polymers: A Perspective on Phase Behavior and Miscibility

open access: yesAdvanced Materials, EarlyView.
Molecular doping of conjugated polymers is fundamentally constrained by thermodynamic phase behavior. This Perspective reframes doping efficiency and stability in terms of miscibility limits, binodals, and solvus boundaries, highlighting the role of effective interaction parameters and charge transfer.

Dynamic time series binary choice [PDF]

open access: yes
This paper considers dynamic time series binary choice models. It proves near epoch dependence and strong mixing for the dynamic binary choice model with correlated errors.

Exploring the Relations Among Knowledge, Contact, and Transgender Prejudice [PDF]

open access: yes
Over the last few years there has been an increase in anti-trans rhetoric and violence towards transgender individuals, the consequences of which continue to adversely affect transgender people’s lives.

Two Ultralow-mass-ratio Binary Systems at Critical Evolutionary Stages

open access: yesThe Astronomical Journal
In this paper, we present photometric observations and period analysis of two totally eclipsing binaries with extremely low-amplitude light curves. Both binaries exhibit typical W Ursae Majoris-type light curves with total eclipses, allowing for the ...
