Lifestyle and mental health disruptions during COVID-19

Significance COVID-19 has affected daily life in unprecedented ways. Drawing on a longitudinal dataset of college students before and during the pandemic, we document dramatic changes in physical activity, sleep, time use, and mental health. We show that biometric and time-use data are critical for understanding the mental health impacts of COVID-19, as the pandemic has tightened the link between lifestyle behaviors and depression. Our findings also suggest a puzzle: Disruptions to physical activity and mental health are strongly associated, but restoration of physical activity through a short-term intervention does not help improve mental health. These results highlight the large impact of COVID-19 on both lifestyle and well-being and offer directions for interventions aimed at restoring mental health. Using a longitudinal dataset linking biometric and survey data from several cohorts of young adults before and during the COVID-19 pandemic (N=682), we document large disruptions to physical activity, sleep, time use, and mental health. At the onset of the pandemic, average steps decline from 10,000 to 4,600 steps per day, sleep increases by 25 to 30 min per night, time spent socializing declines by over half to less than 30 min, and screen time more than doubles to over 5 h per day. Over the course of the pandemic from March to July 2020 the proportion of participants at risk for clinical depression ranges from 46% to 61%, up to a 90% increase in depression rates compared to the same population just prior to the pandemic. Our analyses suggest that disruption to physical activity is a leading risk factor for depression during the pandemic. However, restoration of those habits through a short-term intervention does not meaningfully improve mental well-being.
Neutronics and Nuclear Data for Fusion Technology-Recent Achievements in the EU Programme

An overview is presented of the progress achieved in the EU over the past two years in the field of neutronics and nuclear data for fusion technology. Significant progress has been achieved in making available new data evaluations for neutron transport and activation calculations satisfying the needs for applications to ITER, the International Thermonuclear Experimental Reactor, and the intense neutron source IFMIF (”International Fusion Material Irradiation Facility”), in developing advanced computational tools such as the CAD interface programme for the MCNP code, in extending the capabilities for Monte Carlo based calculations of sensitivities & uncertainties by using the track length estimator, and, in providing the experimental data for a breeder blanket mock-up required for validating related neutronics design calculations.
Nitrogen Fertilizer Increased Bulb Diameter and Yields of True Seed and Bulb – propagated Shallot Varieties

True seed shallots (TSS) have plenty of advantages in comparison to seed bulb (bulb-propagated) shallots. The experiment was conducted with an objective of the effects of N fertilizer rates on the growth and yields of TSS and bulb-propagated shallot varieties. The experiment was conducted at dryland farming area in Buahan village, Kintamani district, Bangli regency from 17 July until 15 October 2015. Four varieties (Tuktuk, BimaBrebes, BiruLancor and Lokal) and four rates of N fertilizer (0, 100, 200 dan 300 kg ha) were the treatments with factorial arrangement in a completely randomized block design with three replicates. Tuktuk was a TSS variety while the other three were bulb-propagated shallot varieties. Results of the experiment showed that TSS Tuktuk was able to adapt in the village of Buahan, Kintamani and produced the highest bulb fresh weight (30.803 ton ha), which was respectively25.73%, 18.30% and 19.77% higher than that of BimaBrebes, BiruLancor and Lokal. Increased in N rates to 200 kg ha significantly increased bulb diameter and bulb fresh weights per ha by 31.03% dan 48.57% respectively. Optimum N rates for Tuktuk, BimaBrebes, BiruLancor and Lokal were respectively 285.122 kg ha, 283.166 kg ha ,208.508 kg ha,241.370 kg ha.
Analysis on Deformation and Stress Characteristics of a Multibraced Pit-in-Pit Excavation in a Subway Transfer Station

As an important part of subway transfer station construction, pit-in-pit (PIP) excavation has always been a key object of monitoring and control. In this study, taking the PIP excavation project of Hefei metro line 4 and line 7 transfer station as the background, combined with on-site monitoring and numerical simulation, the variation law of lateral wall displacement, ground surface settlement, and strut force during the PIP excavation were analyzed. The results showed that the maximum lateral deformation of the pile caused by the excavation of the external pit accounted for 80%–90% of the total deformation and the surface settlement accounted for 70% of the total settlement. The excavation of the inner pit only made the maximum lateral wall displacement of the outer pit and the surface settlement behind the wall increase slightly, the growth rate tended to zero, and the maximum lateral deformation depth was all above the excavation surface, which indicated that, for this project, the inner excavation had little effect on the outer pit retaining structure. In addition, the increased exposure time of the soil at the bottom of the pit and the presence of the corner effect will cause the further development of the structure displacement and the surface settlement. Based on strut force measurements, using the tributary area load distribution procedure, it was obtained that was used as the upper limit index of strut force in the region, where is the weight of the soil and is the excavation depth of the foundation pit. The research conclusions were helpful for the construction and sustainable development of the PIP project.
Improving Linux resource control using CKRM

One of the next challenges faced in Linux kernel development is providing support for work-load management. Workloads with diverse and dynamically changing resource demands are being consolidated on larger symmetric multiprocessors. At the same time, it is desirable to reduce the complexity and manual involvement in workload management. We argue that the goal-oriented workload managers that can satisfy these conﬂicting objectives require the Linux kernel to provide class-based differentiated service for all the resources that it manages. We discuss an extensible framework for class-based kernel resource management (CKRM) that provides policy-driven classiﬁcation and differentiated service of CPU, memory, I/O and network bandwidth. The paper describes the design and implementation of the framework in the Linux 2.6 kernel. It shows how CKRM is useful in various scenarios including the desktop. It also presents pre-liminary performance evaluation results that demonstrate the viability of the approach.
Using Autoencoders for Anomaly Detection in Hard Disk Drives

Nowadays, predicting failures in Hard Disk Drives (HDD) is of key importance for storage service providers and end users. Being able to detect in advance that a disk is going to fail may enable maintenance actions that can avoid severe data losses. For that reason, many researchers had devoted attention to this research topic. Recently, several authors have reported promising results by using attributes collected by the SMART (Self-Monitoring, Analysis and Reporting Technology) system along with machine learning methods. Although the best results were obtained by supervised machine learning methods, it is important to notice that data from degraded HDDs is scarce. Hence, anomaly detection methods arise a promising solution. Among such methods, recent works reported that reconstruction based anomaly detection algorithms had the best performance on HDDs fault detection. In line with such results, in this paper we aim to further investigate the performance of such methods. We conducted tests with classical PCA based methods and neural autoencoder based methods. In addition to testing with the popular reconstruction based autoencoder method we also evaluated a method that analyzes the distribution of the latent space. Additionally we propose a simple formulation to combine both methods. On the basis of our experiments, we verified that autoencoder based methods had the best performances according to the two evaluation metrics. Among such methods, the combination approach had the best overall performance.
Corporate Social Responsibility Disclosure and Financial Performance of Firms in Kenya: A Stakeholder Approach

Using panel data set from companies listed on the Nairobi Securities Exchange in Kenya, a developing country, this paper examines the potential influence of corporate social responsibility disclosure (CSRD) on corporate financial performance. Using data from annual reports, CSRD information was collected for the period 2007-2015 using quantitative content analysis while financial performance data was collected for the period 2008-2016, a one-year lag behind CSRD data. Control variables were firm size, industry type and leverage. There was found to be no statistically significant impact of CSRD on financial performance. Since neutrality of the relationship is empirically proven, the conclusion is that CSRD has little or no contribution to financial performance and the implication is that effective financial reporting for companies listed on the NSE does not include reporting on CSR activities. Theoretically the study proposes that unequal controlling strengths of different stakeholders be assumed under the stakeholder theory for application within different national contexts in order for managers to be able to make the necessary tradeoffs among competing stakeholders.
The Influence of Weather Factors to Mood and Human Behavior on the Stock Market Indices Performance by the Tendency towards Geographical Location

This research tries to determine the weather factors affect mood and human behavior. Some previous researches find that weather can influence human behavior and mood, like concentration, optimism, self-confidence, aggression, and performance. Many weather indicators can affect human behavior and mood, but only few of them have been investigated. In this paper, we use temperature, precipitation, hours of sunshine, and humidity. Mood and behavior make people make decisions based on such indicators, including the trading decision in the stock market. Therefore, mood and behavior turn the investors to become more irrational. In this research, geographical locations are also being included because the difference in location can make a difference in the climate. By using indices return from 44 countries, we get that higher temperature creates more aggression and makes investors more aggressive and risk-taking, leading to the higher returns, hours of sunshine also make investors more optimistic and less risk-averse which leads to higher returns. Higher humidity also leads to a higher concentration. We also find that in Europe and Asia, the effect of weather variables is much stronger than in other continents. Additional results show that stock markets in Europe and Asia are easily affected by weather factors, and the high elevation also has a more significant effect.
The Liquidity Coverage Ratio, Mortgage-Backed Securities, and Mortgage-Market Instability

Under Basel III, banks are subject to a new constraint known as the Liquidity Coverage Ratio (LCR). The LCR is meant to ensure that banks have a sufficient quantity of high quality liquid assets (HQLA) that can be sold during periods of funding stress to meet outflows. In many jurisdictions, mortgage-backed securities (MBS) are an important asset for meeting the LCR. This may result in mortgage-market instability, however, if banks subsidize mortgage credit during periods of high HQLA demand – to acquire additional MBS – and subsequently remove this subsidy once HQLA demand wanes. This paper develops a model of banking to explore this mechanism. The primary result is that intertemporal variation in HQLA requirements, stemming from intertermporal variation in corporate-loan demand, may lead to mortgage and housing market instability.
ROLE OF LIPID AFFINITY AND MEMBRANE PENETRATION IN THE EFFLUX OF CELLULAR CHOLESTEROL AND PHOSPHOLIPID

Lipid-free apolipoprotein (apo) A-I contributes to the reverse transport of cholesterol from the periphery to the liver by solubilizing plasma membrane phospholipid and cholesterol. The features of the apolipoprotein required for this process are not understood and are addressed in the current study. Membrane microsolubilization of human fibroblasts is not specific for apo A-I; unlipidated apos A-II, C, and E incubated with the fibroblast monolayers at a saturating concentration of 50 mg/ml are all able to release cholesterol and phospholipid similarly. To determine the properties of the apolipoprotein that drive the process, apo A-I peptides spanning the entire sequence of the protein were utilized; the peptides correspond to the 11- and 22-residue amphipathic a-helical segments, as well as adjacent combinations of the helices. Of the 20 helical peptides examined, only peptides representing the N-and C-terminal portions of the protein had the ability to solubilize phospholipid and cholesterol. Cholesterol efflux to the most effective peptides, 44 ‐ 65 and 209 ‐241, was approximately 50 and 70%, respectively, of that to intact apo A-I. Deletion mutants of apo E and apo A-I were constructed that have reduced lipid binding affinities as compared with the intact molecule. The proteins, apo A-I (D222‐243), apo A-I (D190 ‐243), apo E3 (D192‐299) and apo E4 (D192‐299) all exhibited a decreased ability to remove cellular cholesterol and phospholipid. These decreases correlated with the reduced ability of these proteins to penetrate into a phospholipid monomolecular film. Overall, the results indicate that insertion of amphipathic a-helices between the plasma membrane phospholipid molecules is a required step in the mechanism of apolipoprotein-mediated cellular lipid efflux. Therefore the lipid binding ability of the apolipoprotein is critical for efficient membrane microsolubilization.
Are people aware of their cognitive decline? Misperception and financial decision making∗

We investigate whether people correctly perceive their own cognitive decline, and the potential financial consequences of misperception. First, we document that older people tend to underestimate their own cognitive decline. Then, we show that individuals who experience a severe cognitive decline, but are unaware of it, are more likely to experience wealth losses. These losses largely reflect decreases in financial wealth and are mainly experienced by wealthier individuals, unaware of their declining memory, who were previously active on the stock market. Our findings support the view that financial losses among unaware respondents reflect bad financial decisions, not rational disinvestment strategies.
Efficacy of Fungicides Against Powdery Mildew (Oidium erysiphoides f. sp. ziziphi) of Ber (Zizyphus mauritiana Lamk)

Four fungicide viz., carbendazim wettable sulphur, tridemorph and dinocap were tested in the laboratory for their efficacy in inhibiting spore germination of ber powdery mildew fungus and found that dinocap at 0.096 and 0.048 ga.i. per litre of water recorded highest percentage of inhibition of spore germination 99.2 and 95.5 respectively. The results of two year field experiment indicated that dinocap which gave highest percentage of inhibition of spore germination gave good control (75.9%) of the disease in the field with highest fruit yield per plant followed by tridemorph at 0.075 ga. i. and wettable sulphur at 0.16 g a.i. with 68.8 and 60.7 percentage disease control over check.
Subterranean Ecosystems: A Truncated Functional Biodiversity

T biodiversity varies among habitats is a basic tenet of ecology. Many hypotheses have been advanced to explain these variations: ecosystem stability and complexity (e.g., Pimm 1984), ecosystem predictability, habitat heterogeneity (e.g., Tilman 1982), and disturbance (the intermediate disturbance hypothesis; Grime 1973). Whatever the cause of its fluctuations, there is evidence that, at a certain threshold, biodiversity is critical to the maintenance of ecosystems. The link between biodiversity and ecosystem function depends on the dissipation of energy, and productivity might be the ultimate factor that controls species richness at local and, to some degree, at regional scales (Ricklefs and Schluter 1993). Ecosystem function accounts for the relative stability of biodiversity ratios between similar habitats of different continents (Caley and Schluter 1997). In contrast, absolute measures of biodiversity in similar habitats of different regions may differ greatly, which has been interpreted as a result of historical processes (Ricklefs and Schluter 1993). Biodiversity patterns of subterranean terrestrial and aquatic ecosystems are in line with these general observations. However, the features of this environment (absence of light, limited variations in temperature, paucity of food, high physical fragmentation) (Ginet and Decou 1977, Camacho 1992) provide unique opportunities to explore biodiversity issues and to test some of the general hypotheses listed above. Subterranean habitats predominate on the continental and ocean margins. Considering the continental earth, 97% of all unfrozen freshwater is subsurface, whereas lakes and rivers represent less than 2%. Terrestrial subterranean habitats encompass the whole unsaturated zone (vadose zone) of underground, most evident in karstic areas (caves, fissures, cracks, etc.), which represent nearly 4% of the rock outcrops of the world. Because they develop in rocks or sediments that protect them against surface environmental changes, these subterranean ecosystems, in contrast to most surface ecosystems which are short-lived (rivers, wetlands, or forests), may persist relatively unchanged for millions of years. In the last two decades groundwater ecology has developed rapidly, forming an important branch of limnology (Stanford and Simon 1992, Gibert et al. 1994, Stanford and Valett 1994, Danielopol et al. 1999). Recent literature has focused on general characteristics of subterranean ecosystems and interac-
Endemic fishes of Croatia

The diversity of Croatia’s ichthyofauna, with regard to the richness of species and endemic species, makes Croatia’s ichthyofauna among the most diverse in Europe. The species richness is a consequence of the country’s geographic position, which includes two large river catchment systems: Adriatic and Danube.
SALINITY EFFECTS ON GROWTH AND APICAL DOMINANCE IN PHASEOLUS VULGARIS L.

The effect of irrigation with saline nutrient solutions on the growth of the main stem and lateral shoots of two varieties of dwarf bean (Phaseolus vulgaris cvs. Balady and Black Valentine) was studied. Saline culture solutions were prepared by adding NaCl to Pfeffer's nutrient solution. Salinity, especially at 20 meq NaCl, promoted the growth of the main stem in cv. Balady, whereas that of cv. Black Valentine was promoted by up to 60 meq NaCl. The growth of lateral shoots was enhanced with salinity up to 20 meq NaCl in cv. Balady and 40 meq Nad in cv. Black Valentine, although higher concentrarations were not suppressive as compared with the control. The levels of some mineral elements in the leaves were determined. Total nitrogen and sodium concentrations in both varieties were increased, whereas phosphorus and potassium concentrations were progressively decreased by salinity.
The effects of either resveratrol supplementation or aerobic exercise training combined with a low fat diet on the molecules of adipogenesis and adipocyte inflammation in high fat diet-induced obese mice

The aim of this study was to compare the effectiveness between resveratrol supplementation and aerobic exercise training with a low fat diet on adipogenesis and inflammatory molecules in adipocytes of high fat diet-induced obese mice. C57BL/6 mice (4 weeks old, n = 15) were fed a high fat diet (45% fat) for 12 weeks first and a low fat diet (l0% fat) for 8 weeks later. The mice were divided into 3 groups: low-fat diet control (HLC; n = 5). Low-fat diet with resveratrol (FILR: n = 5) or low-fat diet with exercise (FILE; n = 5). FILE performed treadmill running for 30-60 mm/day at 10-22 m/mim, 0% grade. five Limes per week for 8 weeks. After 20 weeks of intervention. epididyrnal pads were dissected and analyzed. The body weight and adipose tissue mass of HLE was significantly reduced compared to HLC (p <0.01). FAS expression of I-ILR and FILE were significantly decreased compared to HLC (p <-0.01). ACC expression of FILE was significantly decreased compared to HLC (P < 0.01). The TNF-a expression of HLR and HLE were significantly decreased compared to HLC (P< 0.01). MCP-l expression of HLE was significantly decreased compared to HLC (p <0.05). These results suggest that both aerobic exercise and resveratrol supplementation with a low-fat diet have a positive effect to ameliorate the obese-induced metabolic disturbances compared to a low fat diet alone. However, it seems that aerobic exercise with a low fat diet is more effective to obese-induced metabolic deregulation.
THE INFLUENCE OF SITE FACTORS ON THE COMPOSITION AND STRUCTURE OF SEMI-NATURAL MIXED-SPECIES STANDS OF BEECH (FAGUS SYLVATICA), SILVER FIR (ABIES ALBA ) AND NORWAY SPRUCE (PICEA ABIES) IN THE UPPER DRAGANUL WATERSHED OF NORTH- WEST ROMANIA

Summary Results of redundancy analyses for beech‐conifer stands in the mountains of North-West Romania indicate that Abies alba predominates at mid- to upper-slope positions, on steep gradients and favours southerly aspects. In contrast Picea abies was most abundant on frost-susceptible lower slopes and damper sites with north-westerly aspects. A weak ordination with respect to site factors reflected that Fagus sylvatica may have been at the upper elevation limits for its natural distribution. It is concluded that the two conifer species have site requirements that are relatively complementary for both the production and the conservation of mixed stands.
Rheology of orange fiber enriched yogurt

The aim of this work was to study the effect of orange fiber (obtained from by-products) on yogurt rheological properties (viscosity, syneresis, texture), overall composition, sugars, acidity and sensory characteristics. Different fiber size (0.417-0.701 and 0.701-0.991 mm) and dose (0, 0.6, 0.8, 1% in yogurt formulation) were tested. Rheological properties were determined at weekly intervals during 28 d of storage'at 4°C. Fiber size did not affect any of the studied parameters. Yogurt composition was not affected by fiber addition. Fiber addition slightly decreased yogurt pH but did not affect sugars and lactic acid production. Yogurt rheology was modified by fiber addition and fiber dose. Fiber addition reduced the perception of creaminess and increased acidity perception. In addition to the nutritional benefits of fiber enrichment, 1% fiber enriched yogurt reduced syneresis and improved textural properties of yogurt: increased gel firmness, stickiness and average force measured by back-extrusion.
