Regional Inequalities in Trachoma Prevention in Ethiopia: A Meta‐Analysis

Health Science Reports, Volume 9, Issue 4, April 2026.
ABSTRACT Background and Aims Trachoma remains a significant public health problem in Ethiopia, particularly affecting children. Mothers play a crucial role in implementing preventive practices that interrupt trachoma transmission. Therefore, this systematic review and meta‐analysis seek to address Regional Inequalities in Trachoma Prevention in ...

ASASSN-16dv: Superhumps in a Long-period X-Ray-luminous Dwarf Nova

The Astronomical Journal
Combining a long-term light curve, four-color rapid photometry, and spectroscopic and X-ray observations with a 27-day time base TESS light curve, we present the first dedicated study of ASASSN-16dv, detected as a transient in the All-Sky Automated ...

A Broadband X-Ray Study of the Dwarf Nova SS Cyg during Quiescence and Outburst

The Astrophysical Journal, 2023
We present a broadband X-ray study (∼0.3–50 keV) of the dwarf nova SS Cyg highlighting the changes in the accretion during two phases, the quiescence and the outburst states.

The Secondary Stars of Cataclysmic Variables

, 2011
I review what we know about the donor stars in cataclysmic variables (CVs), focusing particularly on the close link between these binary components and the overall secular evolution of CVs. I begin with a brief overview of the "standard model" of CV evolution and explain why the key observables this model is designed to explain - the period gap and the

A strike for democracy? Migration, the bigot's veto, and the electoral use of force

American Journal of Political Science, Volume 70, Issue 2, Page 491-502, April 2026.
Abstract Politicians and philosophers alike have warned that the spread of anti‐migrant bigotry in the Western world requires a tragic trade‐off regarding immigration policy: Although millions of asylum‐seekers might be owed admission to Western democracies, there are many cases where they nonetheless ought to be denied entry, because their admission ...

Spectroscopic Follow-up on Potential Magnetic Cataclysmic Variables

The Astronomical Journal
Spectroscopic observations of nine cataclysmic variables that have been postulated to contain magnetic white dwarfs were obtained to further characterize their classifications, orbital parameters, inclinations, and/or accretion properties.

Exploring Tolerance Towards Corruption in the European Union Through Experienced Corruption, Perceived Corruption and Institutional Trust

Business Ethics, the Environment &Responsibility, Volume 35, Issue 2, Page 1279-1304, April 2026.
ABSTRACT Corruption is a major problem that undermines the foundations of democracy and reduces citizens' trust in institutions. However, even in the world's most advanced countries, citizens accept certain levels of corruption. This tolerance towards corruption (TC) reduces the impact of anti‐corruption actions and ends up giving a patina of normality

TESS Light Curves of Cataclysmic Variables. V. Improved or Corrected Orbital Periods of 53 Systems

The Astronomical Journal
The long and continuous high-time-resolution coverage of many stars by the Kepler and TESS space missions permit to explore periodic phenomena with a much higher precision than is possible with terrestrial observations.

Polanyi on crisis: The United States, fascism and ecological break‐down

Journal of Law and Society, Volume 53, Issue S1, Page S131-S150, April 2026.
Abstract This article uses Karl Polanyi's understanding of the crisis inherent in liberal economics to analyse a contemporary crisis—Trump's global tariff agenda. It argues that Trump's tariff agenda conforms to Polanyi's interpretation of how the crisis of liberal economics can disintegrate into more malignant forces.
