Asymmetric Solar Polar Field Reversals

open access: yes, 2012
The solar polar fields reverse because magnetic flux from decaying sunspots moves towards the poles, with a preponderance of flux from the trailing spots.

Selective Optical Properties of Cement for Enhanced Radiative Cooling and Energy‐Efficient Construction Materials

open access: yesENERGY &ENVIRONMENTAL MATERIALS, EarlyView.
Cement phases are good materials for radiative cooling thanks to the selective emissivity in IR ATW. Cement powders have high reflectance of solar radiation which reduces the thermal losses. The onset of the absorption curves is defined by bound excitons. Sulfates have higher radiated powers and reflectance than calcium silicates.

Copepods in the Northern Hemisphere [PDF]

open access: yesNature, 1925
IT has long been recognised that the distribution of freshwater copepods has been profoundly influenced by the incidence of the glacial period, since the lake-districts which they inhabit are to a large extent postglacial catchment basins. It so happens that there is a general correspondence between the three leading sub-orders and the three principal ...

Forecasting heart failure: Seasonal alignment of heart failure outcomes in New York

open access: yesESC Heart Failure, Volume 12, Issue 2, Page 819-831, April 2025.
Abstract Background Seasonal variations have been observed in heart failure (HF) hospitalization. Numerous explanatory mechanisms have been proposed, but no prior studies have examined potential contributors directly. Our objective was to identify specific factors that could contribute to seasonal variability using a large longitudinal dataset of HF ...

Inroads into epilepsy through high‐frequency oscillations: Achievements and benchmark areas for improvement

open access: yesEpilepsia, EarlyView.
Abstract High‐frequency oscillations (HFOs) were discovered more than 20 years ago, and since then they have been studied intensively in the context of epilepsy. HFOs encompass a broad spectrum of oscillations, typically ranging from 80 Hz to several kHz, that include both normal and pathological oscillations, documented in people with epilepsy and ...

Solar Latitudinal Distribution of Solar Flares around the Sun and Their Association with Forbush Decreases during the Period of 1986 to 2003 [PDF]

open access: yesJournal of Sciences, Islamic Republic of Iran, 2005
Solar flare events of high importance were utilised to study solar latitudinal frequency distribution of the solar flares in northern and southern hemisphere for the solar cycle 22 to recent solar cycle 23.

Precipitation and Northern Hemisphere regimes

open access: yesAtmospheric Science Letters, 2004
AbstractRainfall anomalies in a longterm integration of general circulation model highlight the non‐stationarity of the ocean–atmosphere coupling in the North Atlantic which becomes manifest in two regimes. Anti‐correlations between the precipitation in the tropical and subtropical western Atlantic illustrate the changes of the Hadley cell with El Niño/

Dynamic patterns of verbal memory function after an initial decline following temporal lobe resection against epilepsy: Sex‐specific differences in the postoperative course

open access: yesEpilepsia, EarlyView.
Abstract Objective This study was performed to investigate the postoperative dynamics of verbal memory function after temporal lobe resection (TLR) in people with temporal lobe epilepsy (PwTLE), with a specific focus on the course following an initial verbal memory decline and the factors influencing later changes.
