The COVID-19 pandemic: model-based evaluation of non-pharmaceutical interventions and prognoses.

Author(s): De Visscher A

An epidemiological model for COVID-19 was developed and implemented in MATLAB/GNU Octave for use by public health practitioners, policy makers, and the general public. The model distinguishes four stages in the disease: infected, sick, seriously sick, and better. The model was preliminarily parameterized based on observations of the spread of the disease. ...

Renyi entropy and mutual information measurement of market expectations and investor fear during the COVID-19 pandemic

Author(s): Lahmiri S; Bekiros S;

The COVID-19 pandemic has seriously affected world economies. In this regard, it is expected that information level and sharing between equity, digital currency, and energy markets has been altered due to the pandemic outbreak. Specifically, the resulting twisted risk among markets is presumed to rise during the abnormal state of world economy. The purpos ...

Investigation into the oil removal from sand using a surface washing agent under different environmental conditions.

Author(s): Bi H, An C, Chen X, Owens E, Lee K

Spilled oil frequently reaches the shorelines and affects coastal biota and communities. The application of surface washing agents is an important shoreline cleanup technique that can help remove stranded oil from substrate surfaces with the advantages of high removal efficiency, low toxicity, and strong economic viability. In this study, the investigatio ...

Ontogenetic shift from aposematism and gregariousness to crypsis in a Romaleid grasshopper.

Author(s): Despland E

Traits of chemically-defended animals can change as an individual grows and matures, and both theoretical and empirical evidence favour a direction of change from crypsis to aposematism. This study examines the suite of traits involved in an unusual opposite shift from aposematism to crypsis in a neotropical toxic-plant-feeding Romaleid grasshopper, Chrom ...

Effect of Fe2+ ions on gypsum precipitation during bulk crystallization of reverse osmosis concentrates.

Author(s): Melliti E, Touati K, Van der Bruggen B, Elfil H

In reverse osmosis desalination, the concentrate is a saline solution that may become supersaturated. Heterogeneous nucleation of salts occurs at the membrane surface, resulting in the buildup of inorganic deposits on the membrane. The inorganic nucleation process, however, is complex in natural waters. Most studies focused primarily on single salt foulin ...

Are sexual functioning problems associated with frequent pornography use and/or problematic pornography use? Results from a large community survey including males and females.

Author(s): Bothe B, Tóth-Király I, Griffiths MD, Potenza MN, Orosz G, Demetrovics Z

There is much debate regarding whether pornography use has positive or negative associations with sexuality-related measures such as sexual functioning problems. The present study aimed to examine differential correlates between quantity (frequency of pornography use-FPU) and severity (problematic pornography use-PPU) of pornography use with respect to se ...

Acetyl-CoA regulation, OXPHOS integrity and leptin level are different in females with different onsets of obesity.

Author(s): Tam BT, Murphy J, Khor N, Morais JA, Santosa S

Although childhood-onset obesity (CO) and adult-onset obesity (AO) are known to lead to distinctive clinical manifestations and disease risks, the fundamental differences between them are largely unclear. The aim of the current study is to investigate the fundamental differences between subcutaneous adipose tissue from CO and AO and identify metabolic dif ...

What Media Helps, What Media Hurts: A Mixed Methods Survey Study of Coping with COVID-19 Using the Media Repertoire Framework and the Appraisal Theory of Stress

Author(s): Pahayahay A; Khalili-Mahani N;

Background: Social and physical distancing in response to the coronavirus disease (COVID-19) pandemic has made screen-mediated information and communication technologies (media) indispensable. Whether an increase in screen use is a source of or a relief for stress remains to be seen. Objective: In the immediate aftermath of the COVID-19 lockdowns, we inve ...

A Cross-Sectional Study on the Impact of Arterial Stiffness on the Corpus Callosum, a Key White Matter Tract Implicated in Alzheimer's Disease

Author(s): Badji A; de la Colina AN; Boshkovski T; Sabra D; Karakuzu A; Robitaille-Grou MC; Gros C; Joubert S; Bherer L; Lamarre-Cliche M; Stikov N; Gauthier CJ; Cohen-Adad J; Girouard H;

Background: Vascular risk factors such as arterial stiffness play an important role in the etiology of Alzheimer's disease (AD), presumably due to the emergence of white matter lesions. However, the impact of arterial stiffness to white matter structure involved in the etiology of AD, includ ...

Synergistic effects of cognitive training and physical exercise on dual-task performance in older adults

Author(s): Bherer L; Gagnon C; Langeard A; Lussier M; Desjardins-Crépeau L; Berryman N; Bosquet L; Vu TTM; Fraser S; Li KZH; Kramer AF;

Background: Studies report benefits of physical exercise and cognitive training to enhance cognition in older adults. However, most studies did not compare these interventions to appropriate active controls. Moreover, physical exercise and cognitive training seem to involve different mechanisms o ...

Understanding the relationship between resource scarcity and object attachment

Author(s): Goldsmith K; Roux C; Cannon C;

People generally respond to resource scarcity through one of two pathways: scarcity-reduction or control-restoration. We draw from recent work on the solidity (versus liquidity) of consumption opportunities to offer a new lens through which to view how the two pathways that follow from resource scarcity relate to object attachment. In this review, we disc ...
