Seasonal Characteristics of Mesoscale Convective Systems Over the Philippines

open access: yesInternational Journal of Climatology, EarlyView.
This study examines how mesoscale convective systems (MCSs) over the Philippines are most frequent during boreal summer, while those in winter are longer‐lived and more intense due to cold surges and enhanced easterly moisture transport. Intraseasonal oscillations, such as the Madden‐Julian Oscillation (MJO) and the Boreal Summer Intraseasonal ...

Noncritical conformal gravity and four-dimensional Liouville theory

open access: yesNuclear Physics B
We study the quantum aspects of the conformal gravity in four dimensions, specifically addressing a known discrepancy in beta functions between general quadratic curvature theories and conformal gravity, which corresponds to two scalar degrees of freedom.

Sewage Sludge and Cashew Bagasse Biochars Promote Changes in Selected Physical Attributes Related to the Structure of Degraded Dryland Soil

open access: yesJournal of Plant Nutrition and Soil Science, EarlyView.
This study evaluated biochars from co‐pyrolysis of sewage sludge and cashew residues on physical quality of a degraded loamy sand soil. SPB applied at 20 Mg ha−1 reduced bulk density by 7.74%, whereas most porosity attributes were driven by soil reconsolidation rather than biochar. Aggregate stability varied with biochar type, with SPB promoting larger

Enhancing Mars Gravity Field Solutions with China’s Tianwen-1 Tracking Data

open access: yesThe Astrophysical Journal
The Tianwen-1 (TW1) mission, which successfully entered Mars's orbit in 2021, provides a valuable data set for enhancing the understanding of Mars’s gravity field.

Is It a Matter of Visibility Over Viability? CEO Narcissism and the Strategic Trade‐Off in Corporate Diversification

open access: yesStrategic Change, EarlyView.
ABSTRACT This study examines how CEO narcissism shapes corporate diversification strategies, addressing gaps in upper echelon and agency theories. Using a sample of 388 CEOs across 319 firms, we find that narcissistic CEOs drive higher levels of overall corporate diversification but exhibit a strategic trade‐off: they strongly favor unrelated ...

Lectotypifications and taxonomic changes in the holoparasitic Orobanchaceae

open access: yesNordic Journal of Botany, EarlyView.
Based on further extensive studies of specimens in various herbaria, lectotypes are designated for many taxa of holoparasitic Orobanchaceae. In particular, 47 names in the genera Boschniakia (incl. Xylanche), Cistanche, Orobanche, Phelipanche and Phelypaea are lectotypified.

A Review of Bioarcheological Investigations in Iron Age Cambodia

open access: yesInternational Journal of Osteoarchaeology, EarlyView.
ABSTRACT Archeological research within Cambodia is quite extensive, with significant projects led by both Cambodian archeologists and international researchers alike. Many of these projects have uncovered human skeletal remains. This article reviews archeological human skeletal studies in Cambodia, synthesizing published and unpublished data, primarily

Multi-resolution analysis of gravity anomalies: A comparative study of modern and spherical approximation techniques

open access: yesNova Geodesia
Analysing gravity anomalies is a key method of understanding the Earth’s shape, structure, and subsurface composition. This is done by modeling the Geoid, an irregular surface, into a regular sphere or ellipsoid for easy computations.

Anomalies in quantum gravity

open access: yesPhysics Letters B, 1987
Abstract We look for a relation between the Christodoulakis-Zanelli Schwinger term in the commutators of the constraints and the Weyl diffeomorphism cocycle. We discuss the problem of anomalies in pure Quantum Gravity. We underline the particular role of the Weyl degree of freedom in all approaches to Quantum Gravity.
