Unveiling Low-frequency Eclipses in Spider Millisecond Pulsars Using Wideband GMRT Observations

The Astrophysical Journal
Eclipses of radio emission have been reported for ∼58 spider millisecond pulsars (MSPs), of which only around 19% have been extensively studied. Such studies at low frequencies are crucial for probing the properties of the eclipse medium.

Physical parameters of 62 eclipsing binary stars using the ASAS-3 data$-$I

, 2010
We present a detailed light curve analysis of publicly available V band observations of 62 binary stars, mostly contact binaries, obtained by the All Sky Automated Survey (ASAS)-3 project between 2000 and 2009.

Punchline with(out) purpose: Integrating research on instructional humour and seductive details

British Journal of Educational Psychology, EarlyView.
Abstract Introduction We integrated research on instructional humour and seductive details to investigate when affiliative course‐related humour is effective or rather ineffective for learning. We assumed that instructional humour without a cognitive function (irrelevant humour) would have detrimental effects on learning performance resembling the ...

Decoding the Role of Caveolin‐1 in Morphological Diversity and Self‐Renewal of Breast Cancer Cells

Cell Proliferation, EarlyView.
The silence of caveolin‐1 (Cav‐1) reproduced the morphological evolutionary behaviour of cancer cells, which is similar to the epithelial‐mesenchymal transition process. And Cav‐1 dependent morphological changes could affect cancer cell self‐renewal capacity through maintaining the morphological stability.

Pulsations in close binaries: challenges and opportunities

EPJ Web of Conferences, 2015
CoRoT and Kepler provided a precious by-product: a number of eclipsing binaries containing variable stars and, among these, non-radial pulsators. This providential occurrence allows combining independent information from two different phenomena whose ...

Maternal Paradox: When Nurturer Meets the Knife, Living Organ Donation From Daughters to Mothers in Türkiye

Sociology Lens, EarlyView.
ABSTRACT This article uses the case of living organ donation from daughters to mothers in Türkiye to examine how maternal subjectivities are constructed, enacted, and transformed within specific cultural contexts. In Türkiye, motherhood is both culturally idealized and politically reinforced as the moral core of womanhood.

Error Correction Learning of Second Language Verbal Morphology: Associating Imperfect Contingencies in Naturalistic Frequency Distributions

Language Learning, EarlyView.
Abstract We investigate what is learned from exposure to usage in verbal morphology using an error correction mechanism within an associative learning framework. We computationally simulated how second language (L2) learners would respond to naturalistic input of aspectual usage, characterized by “imperfect contingencies,” given two types of ...

A Photometric and Spectroscopic Investigation of 11 TESS Eclipsing Contact Binaries

The Astrophysical Journal
By cross-matching the eclipsing binary catalog provided by A. Prša et al. with Large Sky Area Multi-Object Fiber Spectroscopic Telescope medium-resolution spectra, we obtained 11 targets.
