Growth of Oxygen Environment of the Newborn Vocal Fold Maculae Flavae as a Stem Cell Niche
Laryngoscope Investigative Otolaryngology, Volume 11, Issue 3, June 2026.ABSTRACT Objectives Accumulating evidence indicates that the anterior and posterior maculae flavae of the human vocal fold mucosa function as niches for tissue stem cells. This study aimed to characterize the oxygen microenvironment of the maculae flavae in the newborn vocal fold and to clarify its potential involvement in metabolic regulation and the ...

Relationship between food quality and body size of common vole in different habitats
Pest Management Science, Volume 82, Issue 6, Page 5206-5215, June 2026.The body size of the common vole in crop fields (alfalfa, rape, cereals) is larger than in less‐cultivated habitats (forests, clearings, set‐aside) and is not related to food quality. Abstract BACKGROUND There is a close relationship between habitat, food and demographic parameters of common vole populations.

A semi-automated method to reveal the evolution of each sunspot group in a solar cycle
, 2018 Sunspots are the most important indicator of the magnetic activity on the solar surface during a cycle. Every sunspot group is formed and shaped by the magnetic field of the Sun.

Low-latitude Sunspot Group Tilt Angles in 15–24 Activity Cycles
The Astrophysical JournalAn analysis of the tilt angles of the active regions in 15–24 activity cycles was performed. We used data from measurements of magnetic fields in the sunspot umbra in the period 1918–2019 at the Mount Wilson Observatory, as well as the tilt angles of ...

AGU Advances, Volume 7, Issue 3, June 2026.Abstract In Low Earth Orbit (LEO), atmospheric drag is the dominant source of trajectory prediction error below approximately 700 km altitude, primarily due to inaccuracies in thermospheric density models. This work presents a method for temporally deconvolving Energy Dissipation Rates (EDRs) to produce single‐satellite density estimates, which can be ...

"A transfer function model for the sunspot cycle"
, 2021 The mean annual sunspot record for the time interval 1700–2002 can be considered as a sequence of independent, partly overlapping events, triggered quasi-periodically at intervals of the order of 11 years.

Relationships between relative sunspot numbers and air temperature
Meteorologische Zeitschrift, 1993 Monthly means of relative sunspot numbers (1749-1991) and temperature anomalies of the two hemispheres (1851-1987 for the northern and 1858-1987 for the southern hemisphere) have been analysed by means of spectral methods.
