Is EEG theta\beta ratio predictive towards the negative effects of stress on cognitive performance in individuals suffering from performance anxiety? Can we improve resilience to performance anxiety by using a theta\beta ratio neurofeedback intervention?

Detecting planets during their formation stages is crucial for understanding the history and diversity of fully developed planetary systems like our own. However, observing young planets directly is challenging because they are often deeply embedded within their host protoplanetary discs, rich in gas…

In times of hardships or crisis, local people know how to deal with it using their resourcefulness. Although efforts are sometimes made by the government to help them, they are fully aware that community support is at least equally important.

Consequences for sediment stability and seston trapping

Plants are colonized by an astounding number of microorganisms that can provide different life-support functions, including nutrient acquisition and protection against (a)biotic stresses like drought or pathogen attack.

Glycoside hydrolases (glycosidases/GHs) are widely abundant enzymes in all kingdoms of life and are important biocatalysts that catalyze the hydrolysis of glycosidic linkages in oligo/polysaccharides, glycoproteins and glycolipids with tremendous efficiency

The figure of the barbarian has captivated the Western imagination from Greek antiquity to the present. Since the 1990s, the rhetoric of civilization versus barbarism has taken center stage in Western political rhetoric and the media. But how can the longevity and popularity of this opposition be accounted…

Assessment of teaching is currently becoming more and more common practice. As such assessment is generally based on complex, qualitative data from multiple sources (e.g., lesson plans, video-taped lessons, written reflections of the teacher on his or her performance), the overall quality of the assessment…

At LUCL we study almost all aspects of a wide range of African languages. From phonology to anthropological linguistics, from theoretical syntax to urban youth languages, we study it all.

LUGO is launching Green Teams throughout the University, starting with the Law Faculty.

Robotics, using social mechanisms like hormonal modulation, may accelerate our understanding of core sociality principles. By looking at social robotics through an evolutionary lens, we propose this field as a promising framework to investigate the fundamental bricks of sociality from an evolutionary…

The high prevalence of pure red cell aplasia in Thailand has been associated with the sharp increase in number of recombinant human erythropoietin (rhEPO) copy products, based on a classical generic regulatory pathway, which have entered the market.

Plant-microbe interaction resulted in different physio/chemical responses by host plant and interacting rhizobacteria.

Multi-objective evolutionary computation aims to find high quality (Pareto optimal) solutions that represent the trade-off between multiple objectives.

Cholesterol influences many pathways, including serving as precursor for adrenal steroidogenesis. Imbalance of cholesterol levels has been implicated in several diseases including cardiovascular diseases and its underlying pathology, atherosclerosis.

Indicators to measure progress in de-linking economic growth and environmental pressure.

The skin barrier function is provided by the stratum corneum (SC). The lipids in the SC are composed of three lipid classes: ceramides (CERs), cholesterol (CHOL) and free fatty acids (FFAs) which form two crystalline lamellar structures. In the present study, we investigate the effect of CER chain length…

In this article, the authors analyse two major factors that deepen informality, namely multipolar geopolitics and the rise of non-state actors.
