Chlorella vulgaris biorefineries: sustainable biofuels and high‐value carbon capture

Biofuels, Bioproducts and Biorefining, EarlyView.
Abstract Global reliance on fossil fuels has created urgent economic and environmental challenges, yet large‐scale use of algal biomass remains limited by production costs. Industrial scaling is constrained by inefficient harvesting and the technical challenges of processing recalcitrant cell walls.

Heartbeat of the sun from principal component analysis and prediction of solar activity on a millenium timescale [PDF]

, 2015
We derive two principal components (PCs) of temporal magnetic field variations over the solar cycles 21-24 from full disk magnetograms covering about 39% of data variance, with σ = 0.67. These PCs are attributed to two main magnetic waves travelling from

The segregation of Calb1, Calb2, and Prph neurons reveals distinct and mixed neuronal populations and projections to hair cells in the inner ear and central nuclei

Developmental Dynamics, EarlyView.
Three populations of hair cells have a distinct expression of Calb1 and Calb2. (A, A′D) The central is highly positive for Calb1 while surrounding HC are positive for Calb2. Later, a calyx forms primarily with Calb1. (B, B′, D′, D″) Saccule and utricle start out positive for Calb2 but will upregulate the Calb1 in the striola that is primarily forming ...

14C-Based Sunspot Numbers for the Last Millennium Encompass the Full Range of Variability: Extreme Value Theory [PDF]

We examine the statistical properties of extreme solar activity levels through the application of the extreme value theory to the annual sunspot number series reconstructed from 14C data spanning the last millennium. We have used the extreme value theory

Evidence for Solar Modulation on the Millennial-Scale Climate Change of Earth

Universe, 2020
In this study, we use available reconstructed data to investigate periodicities of solar activity (i.e., sunspot number) and the Earth’s climate change (temperatures of Lake Qinghai in China and Vostok in Antarctica, the GISP δ18O climate record of ...

Uniting the Sun’s Hale magnetic cycle and “extended solar cycle” paradigms

Frontiers in Astronomy and Space Sciences, 2022
Through meticulous daily observation of the Sun’s large-scale magnetic field the Wilcox Solar Observatory (WSO) has catalogued two magnetic (Hale) cycles of solar activity.

Genetic epilepsies with myoclonic seizures: Mechanisms and syndromes

Epilepsia Open, EarlyView.
Abstract Genetic epilepsy with myoclonic seizures encompasses a heterogeneous spectrum of conditions, ranging from benign and self‐limiting forms to severe, progressive disorders. While their causes are diverse, a significant proportion stems from genetic abnormalities.

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.

Diabetic Retinopathy in Primary Healthcare in a Brazilian Municipality: A Cross‐Sectional Study Using Teleophthalmology

Health Care Science, EarlyView.
The prevalence of diabetic retinopathy was estimated to be 28.3% (95% CI 21.1–35.4), with most of the cases corresponding to mild non‐proliferative diabetic retinopathy. ABSTRACT Background Diabetic retinopathy is a complication of diabetes and the leading cause of irreversible blindness in people of working age.

Major Cybersecurity Breaches: Shaping Corporate Cybersecurity Policies and Closing the Gaps

Journal of Corporate Accounting &Finance, EarlyView.
ABSTRACT As digitalization accelerates, cybercrime has intensified in both scale and impact over the past two decades. This study aims to critically examine major cybersecurity events, assess them through the lens of routine activity theory, examine insight from three other established criminological and organizational theories, and address central ...
