Quantitative Evaluation of Surface Whitening Mitigation via Thermal Annealing in Carbon Fiber/Polyphenylene Sulphide Thermoplastic Composite Laminates

Polymer Composites, EarlyView.
Mitigation of surface whitening in CF/PPS laminates via thermal annealing and quantitative image‐based assessment. ABSTRACT Surface whitening is a manufacturing‐induced surface defect in thermoplastic composites, resulting from non‐uniform shrinkage and near‐surface resin instability during cooling.

Short-period Heartbeat Binaries from TESS Full-frame Images

The Astrophysical Journal Supplement Series
We identify 240 short-period ( P ≲ 10 days) binary systems in Transiting Exoplanet Survey Satellite data, 180 of which are heartbeat binaries. The sample is mostly a mix of A- and B-type stars and primarily includes eclipsing systems, where over 30% of ...

Are client ties pre‐entry resources? Performance implications of client tie diversification

Strategic Management Journal, EarlyView.
Abstract Research Summary This study investigates client tie diversification, where firms enter markets with existing clients. Recognizing the theoretical basis for both positive and negative performance implications, the paper adopts a question‐driven approach and discovers a strong negative correlation between client tie diversification and firm ...

Characterization of the Pore Environments in Covalent Organic Frameworks by Dynamic Spin Probe Exchange

Small, EarlyView.
Covalent organic frameworks (COFs) with alkyl or triethylene glycol pore linings are probed with water‐dissolved nitroxide radicals using CW EPR spectroscopy. Adsorption affinity, local polarity, and radical concentration inside the pores are quantified, revealing hydrogen bonding, dipolar, and π‐π interactions that govern guest binding, which ...

A Systematic Search for Big Dippers in ASAS-SN

The Open Journal of Astrophysics
Dipper stars are extrinsically variable stars with deep dimming events due to extended, often dusty, structures produced by a wide range of mechanisms such as collisions, protoplanetary evolution or stellar winds.

Covalent Organic Framework Electrolytes for Solid‐State Lithium Batteries: Designing Ion Highways for Next‐Generation Energy Storage

Small, EarlyView.
Covalent organic frameworks provide a structurally programmable platform for solid‐state lithium batteries. This review outlines a design framework linking structural descriptors to ion‐transport metrics. It examines mechanisms of confinement, channel architecture, and hybrid designs, addressing the reasons for the occasional failure of high intrinsic ...

Practically Error‐Free Junctions Enable Solving Large Instances of Exact Cover Problems Using Network‐Based Biocomputation

Small, EarlyView.
Scaling nanofluidic channel geometries to sub‐200 nm is demonstrated to suppress junction guiding errors in network‐based biocomputing. The resulting increase in path fidelity enables experimental solution of Exact Cover instances with more than 33 million possible solutions, establishing a new benchmark for network‐based biocomputing. ABSTRACT Network‐

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.

ECLIPSING BINARY STARS : LIGHT CURVE MODELS AND SOFTWARE

Odessa Astronomical Publications, 2017
The importance of studying Eclipsing Binary Stars for the determination of fundamental stellar data is sketched. The eclipsing binaries, originally classified phenomenologically, are now understood on the basis of much firmer physics and the improved ...

Identity Entanglement: Rethinking Marginality through the Intersectional, Liminal, and Antithetical

Symbolic Interaction, EarlyView.
While identity research has given sustained attention to marginality, intersectionality, and the effects of power on identity, the formal interactional dynamics through which identities are constituted remain limited. I present identity entanglement as a useful framework for better understanding and articulating the relational complexities of identity.
