Mental Well-Being of Czech University Students: Academic Motivation, Self-Compassion, and Self-Criticism

University students in the Czech Republic suffer from a low level of mental well-being. Research in other university student populations suggests that academic motivation, self-compassion, and self-criticism are strongly related to mental well-being. Students who are motivated to study, are kind toward themselves, and are less judgmental of themselves tend to have a high level of mental well-being. These relationships had not been evaluated in Czech students. Accordingly, this cross-sectional study aimed to evaluate the relationships between mental well-being, academic motivation (intrinsic motivation, extrinsic motivation, and amotivation), self-compassion (self-reassurance) and self-criticism (self-inadequacy and self-hate). Of 130 students approached, a convenience sampling of 119 psychology students at a university in the Czech Republic completed a survey regarding these constructs. Correlation, regression, and path analyses were conducted. Mental well-being was positively associated with intrinsic motivation and self-compassion, and negatively associated with amotivation and self-criticism. Self-compassion was identified as the strongest predictor of mental well-being. Lastly, intrinsic motivation mediated the pathway from self-compassion to mental well-being, but not the one from self-inadequacy to mental well-being, and the one from self-hate to mental well-being. Our findings can help educators to identify effective means to protect students’ mental well-being. Cultivating students’ self-compassion may be helpful to protect their mental well-being. University staff and educators in the Czech Republic need to consider ways to embed self-compassion training into their students’ programmes or university life.
Spectroscopic Redshifts for Seven Lens Galaxies

The use of gravitationally lensed quasars for cosmological applications and as probes of galaxy structure and evolution requires knowledge about the lens redshift, which is unknown for a large fraction of lenses. We report Very Large Telescope observations of 11 lensed quasars, designed to measure the redshifts of their lens galaxies. We successfully determined the redshifts for seven systems, five of which were previously unknown. The securely measured redshifts for the lensing galaxies are: HE 0047-1756 z = 0.408; PMN J0134-0931 z = 0.766; HE 0230-2130 z = 0.522; HE 0435-1223 z = 0.455; SDSS 0924+021 z = 0.393; LBQS 1009-025 z = 0.871; and WFI J2033-472 z = 0.658, all with uncertainties of 0.001. For four additional systems (BR I0952-0115, Q1017-207, Q1355-2257, and PMN J1632-003) we estimate tentative redshifts based on some features in their spectra.
Highly Sensitive Detection of Isoniazid Heteroresistance in Mycobacterium Tuberculosis by Droplet Digital PCR

Purpose The drug resistance of Mycobacterium tuberculosis constitutes a major public health threat. Existing approaches make it challenging to detect low levels of drug-resistant TB, also known as heteroresistance (HR), in a population. The recently found droplet digital PCR (ddPCR) is a sensitive method for determining the precise amount of nucleic acid in a sample. We used ddPCR to test the Mycobacterium tuberculosis heteroresistance because it delivers more exact quantitative data without the need for a reference curve. Patients and Methods A TaqMan-MGB probe mutation detection assay was developed in order to determine the mutant and wild-type sequences of the isoniazid resistance katG (315) gene. We produced heteroresistant MTB combinations, which were subsequently identified by ddPCR, qPCR, and MeltPro/INH. In addition, 21 clinical sputum samples with positive smears were used to validate each method’s capacity to determine HR in sputum. Results We discovered that ddPCR can detect mutant sequences in as few as 0.01% of a combination. DeepMelt TB/INH, which is less sensitive in comparison, cannot detect HR with high resolution and requires a mutation rate of 50% to identify. qPCR likewise has a high resolution of 0.02%, but unlike ddPCR, it cannot determine the exact number of mutations. Our assay is applicable to sputum as well. ddPCR found a katG 315 substitution in two sputums with extremely low values of HR (0.26% and 0.14%). In 21 samples of clinical sputum, the HR prevalence of INH was 9.5%. Conclusion This work demonstrates that a well-designed ddPCR HR detection test can detect low levels of HR with high accuracy and consistency and gives new information for the clinical diagnosis of drug resistance.
Rapamycin Liposomes Combined with 5-Fluorouracil Inhibits Angiogenesis and Tumor Growth of APC (Min/+) Mice and AOM/DSS-Induced Colorectal Cancer Mice

Background Transgenic C57BL/6-APC(Min/+) spontaneous cancer mouse model and the Azoxymethane (AOM)/Dextran Sulfate Sodium (DSS) chemically induced orthotopic colorectal cancer mouse model represented distinct pathogenesis of colorectal cancers. Our previous study revealed that the combination of Rapamycin liposomes (Rapa/Lps) and 5-Fluorouracil (5-FU) has anti-colorectal cancer effects. However, the therapeutic efficacy of Rapa/Lps and 5-FU in other colorectal cancer mice models is yet to be thoroughly explored. The purpose of this study was to investigate the anti-tumor effect of Rapa/Lps combined with 5-FU in vivo and in vitro. Methods In this study, we evaluated the effect of Rapa/Lps and 5-FU on APC (Min/+) mice and AOM/DSS-induced colorectal cancer mice. The small intestine, colorectum, serum, and plasma of mice in each group were collected following sacrifice to record the number of tumors. HE staining was utilized for observing pathological damage to intestine tissues. Tube formation assay, Transwell assay, wound healing assay, Western Blot were used to explore the anti-angiogenesis effect of drugs in HUVECs. Results As expected, Rapa/Lps and 5-FU significantly suppressed tumor formation, decreased the number of tumors, and tumor load both in two mouse models, and had no influence on mouse weight. Mechanically, the anti-tumor effect of the drug also was associated in inhibiting angiogenesis and proliferation. Furthermore, we found that Rapa/Lps obviously inhibited HUVECs tube formation and migration. Conclusion Altogether, we revealed the Rapa/Lps synergism with 5-FU decreased colon and small intestinal tumorigenesis in AOM/DSS-treated and APC (Min/+) mice, respectively, and correlated with anti-angiogenesis.
Two-component Jaffe models with a central black hole - I. The spherical case

Dynamical properties of spherically symmetric galaxy models where both the stellar and total mass density distributions are described by the Jaffe (1983) profile (with different scale-lenghts and masses), are presented. The orbital structure of the stellar component is described by Osipkov--Merritt anisotropy, and a black hole (BH) is added at the center of the galaxy; the dark matter halo is isotropic. First, the conditions required to have a nowhere negative and monothonically decreasing dark matter halo density profile, are derived. We then show that the phase-space distribution function can be recovered by using the Lambert-Euler $W$ function, while in absence of the central BH only elementary functions appears in the integrand of the inversion formula. The minimum value of the anisotropy radius for consistency is derived in terms of the galaxy parameters. The Jeans equations for the stellar component are solved analytically, and the projected velocity dispersion at the center and at large radii are also obtained analytically for generic values of the anisotropy radius. Finally, the relevant global quantities entering the Virial Theorem are computed analytically, and the fiducial anisotropy limit required to prevent the onset of Radial Orbit Instability is determined as a function of the galaxy parameters. The presented models, even though highly idealized, represent a substantial generalization of the models presentd in Ciotti et al. (2009), and can be useful as starting point for more advanced modeling the dynamics and the mass distribution of elliptical galaxies.
Anomalous Fluctuations of the Condensate in Interacting Bose Gases

We find that the fluctuations of the condensate in a weakly interacting Bose gas confined in a box of volume $V$ follow the law $ \sim V^{4/3}$. This anomalous behaviour arises from the occurrence of infrared divergencies due to phonon excitations and holds also for strongly correlated Bose superfluids. The analysis is extended to an interacting Bose gas confined in a harmonic trap where the fluctuations are found to exhibit a similar anomaly.
Voltammetric Ion Sensing with Ionophore-Based Ion-Selective Electrodes Containing Internal Aqueous Solution, Improving Lifetime of Sensors

The possibility of voltammetric ion sensing is demonstrated, for the first time, for ion-selective electrodes (ISEs) containing an internal aqueous solution. ISEs selective to calcium, lithium and potassium ions are used as model systems. The internal solution of the ISEs contains a chloride salt of the respective cation and a ferrocenemethanol or ferrocyanide/ferricyanide redox couple. A platinum wire is used as the internal reference electrode. It is shown, theoretically and experimentally, that the dependence of oxidation and reduction peak potentials on the sample composition obeys the Nernst law, while the peak currents virtually do not depend on the sample composition. Thus, the electrode behavior is similar to that reported by Bakker’s group for solid contact ISEs with ultra-thin membranes (200–300 nm). It is shown that the use of classical ISEs with relatively thick membranes (100–300 µm) and internal aqueous solution allows for the sensor lifetime of about one month. It is also shown that use of a suitable background electrolyte allows for improvement of the detection limits in voltammetric measurements with ISEs.
Sustainable Smart Homes and Community Happiness in the Malaysian Context

Sustainable smart houses are one of the methods through which all these factors can be touched upon because such houses provide social well-being and cause less damage to the environment. Therefore, this study analysed the predictors of purchase behaviour of sustainable smart houses and their impact on community happiness. Among the predictors which are part of this study include attitude, subjective norms, perceived behavioural control, cost, intention, and social media networks. Data were collected through a questionnaire survey from 187 Malaysian respondents, and SmartPLS was used for data analysis. Results revealed that purchase of sustainable smart houses does have an impact on community happiness. It establishes the extent to which community well-being has been prioritised by local property developers. In addition, it suggests strategies to help these developers to materialise the goals of smart and sustainable property development focusing on community well-being.
Refining Cotton Replanting Recommendations

The decision to replant suboptimal cotton (Gossypium hirsutum L.) stands has become more challenging in recent years because the suggested retail price per bag of replanting seed has increased by more than 25%. Previous studies have justified replanting when ≥ 50% of planted area is occupied by skips ≥ 0.91 m (3 ft). Revision of replanting recommendations was deemed necessary with the introduction of more advanced and accurate plant and skip detection methods. The objective of this study was to update replanting recommendations using unmanned aerial vehicles (UAVs). The study was conducted at three sites in eastern North Carolina during the 2019 and 2020 growing seasons. Each site had an early- and a late-planted trial. Treatment combinations were produced using various ratios of DP 1646 B2XF and DP 493 cotton seed. Simulated replanted plots were planted with 100% DP 1646 B2XF three to four weeks after initial planting. Following emergence, glyphosate and glufosinate were applied to terminate all conventional seedlings and produce random skips. Cotton skips were detected using a Zenmuse X5 RGB sensor mounted on a UAV. Yield was regressed to the percentage of planted area occupied by skips > 0.91 m. In 2019, the replanted treatment did not yield higher than earlier planted treatments but, in 2020, yields were significantly higher in the replanted treatment compared to most earlier planted treatments. The data suggest that a replant should be triggered when 30 to 40% of the planted area is occupied by skips ≥ 0.91 m.
The Examination of Teachers’ Perceptions Relating to Job Satisfaction: A Mixed-Method Study

This study aimed to examine the perceptions of job satisfaction of teachers working in public schools. A concurrent design is one of the mixed methods research designs where qualitative and quantitative research methods are used together. The research was designed with the phenomenology pattern, one of the qualitative research designs, and the hatch pattern, which is one of the quantitative research types. The data in the qualitative part of the research were analyzed by content analysis method. The data in the quantitative part was analyzed with statistical methods such as mean and standard deviation. While the sample of the quantitative part consists of 324 teachers, in the qualitative part, 43 teachers determined from the same sample constitute the study group. The quantitative results showed that the teachers had a high level of internal satisfaction and a moderate external satisfaction perception. It has been concluded that teachers have a medium level of job satisfaction perception in all job satisfaction. The qualitative results revealed that the teachers had negative views on social prestige, adequate pay, being appreciated by the manager, and positive views on being satisfied with the workplace, being satisfied with the manager, and feeling conscientious about their work. It is expected that the research results will provide data for both policymakers in education and school administrators who affect teacher job satisfaction in practice.
The Bar Pattern Speed of Dwarf Galaxy NGC 4431

We present surface photometry and stellar kinematics of NGC 4431, a barred dwarf galaxy in the Virgo Cluster undergoing a tidal interaction with one of its neighbors, NGC 4436. We measured its bar pattern speed using the Tremaine-Weinberg method and derived the ratio of the corotation radius, DL, to the bar semimajor axis, aB. We found DL/aB = 0.6 at 99% confidence level. Albeit with large uncertainty, the probability that the bar ends close to its corotation radius (i.e., 1.0 ≤ DL/aB ≤ 1.4) is about twice as likely as that the bar is much shorter than the corotation radius (i.e., DL/aB > 1.4).
Disruption of a Planet Spiraling into its Host Star

The processes leading to the deformation and destruction of planets spiraling into the convective envelope of their host stars are described. The planet is compressed by ram pressure and deformed into a flattened shape, for which a quantitative model is developed. Compression increases the planet’s density contrast with the envelope and its gravitational binding energy. This increases the survivability, especially of gas planets. An estimate is given for the depth of disruption by ram pressure, and for the subsequent fragmentation of the remnants. We show how the debris of rocky or iron planets, instead of mixing through the convection zone (CZ), sinks below the base of the CZ. The timescale of the entire sequence of events is of the order of a few orbital times of the planet. If spiral-in of (partly) icy, rocky or iron planets has happened to the pre-main sequence Sun, then this could account for the higher opacity below the base of the CZ, as inferred from helioseismology.
Persistent Postural Perceptual Dizziness in Episodic Vestibular Disorders

Benign Paroxysmal Positional Vertigo (BPPV), Vestibular Migraine (VM), and Meniere Disease (MD) are among the most common episodic vestibulopathies. Persistent Postural Perceptual Dizziness (PPPD) is a chronic functional vestibular disorder that can arise in patients suffering from one or more of these conditions. We analyzed the role of these vestibular disorders as single or multiple associated comorbidities and as a precipitating condition for PPPD. A total of 376 patients suffering from dizziness with a known history of single or multiple vestibular disorders were preliminarily evaluated. We conducted a careful anamnesis to determine whether the reported dizziness could meet the diagnostic criteria for PPPD. PPPD was diagnosed in 24 cases; its incidence in patients with history of a single comorbidity or multiple vestibular comorbidities was 3.9% and 22.4%, respectively. BPPV, VM, and MD were identified as a precipitating condition in 2.34%, 16.45%, and 3.92%, respectively. BPPV constituted a precipitating condition mainly at the first episode. We observed that the presence of multiple vestibular comorbidities (BPPV, VM, and MD) in patients’ clinical history increased the risk of PPPD. VM plays a significant role in representing a precipitating condition for PPPD, both when present individually or in association with the other vestibular disorders.
Fully Distributed Algorithm for Resource Allocation Over Unbalanced Directed Networks Without Global Lipschitz Condition

This note investigates the distributed optimal resource allocation problem of multiagent systems over unbalanced directed networks under the relaxed condition that the gradients of local cost functions are locally Lipschitz. The objective is to cooperatively drive the decision variables of the agents to the optimal solution, which minimizes the sum of the local cost functions, while ensuring that the network resource constraints and local feasibility constraints are satisfied. A novel distributed algorithm is developed over unbalanced directed network topologies based on the topology balancing technique and adaptive control approach. The developed algorithm is fully distributed in the sense that it depends on neither the global Lipschitz continuity of the gradients nor prior global information about the network connectivity. By regarding the proposed algorithm as a perturbed system, its input-to-state stability with a vanishing perturbation is first established, and asymptotic convergence of the decision variables toward the optimal solution is then proved.
Exploring the effect of Jasmonic Acid for Aphids control for improving the yield of Triticum aestivum varieties

Many biotic and abiotic factors influence the production of wheat (Triticum aestivum L.). Among biological agents, aphids are destructive pests effecting wheat yield drastically. This study was designed to evaluate the impact of foliar Jasmonic acid spray on aphid population as well as on plant growth during aphid infestation in two wheat varieties i.e., Borlaug-2015 and Zincol-2015. Plants are cultivated in pots and treated with jasmonic acid at concentrations of 0.1 and 1 mM (JA). The results revealed that length of shoot and roots decreased after aphid stress and was improved (21–24%) by JA spray. Photosynthetic pigments increased after applying the jasmonic acid spray compared to control plants. Jasmonic acid spray helped the plants to recover from aphid stress by enhanced production of antioxidant enzymes CAT (Catalase) (65–71%), SOD (Superoxide dismutase) (71–74%) and POD (Peroxidase) (61–65%). Consequent to improved defence system, plants treated with JA had fewer aphids as compared to control (60–73% reduction), 24 h after spray. The higher concentration of JA (1 mM) proved more effective as compared to 0.1 mM jasmonic acid. Moreover, Zincol-2015 appeared tolerant as compared to Borlaug-2015 against aphid infestation. The application of jasmonic acid as an exogenous foliar application showed an overall positive impact on the physiological and biochemical attributes of both varieties. It helps the plants to enhance resistance against the biotic stress and can be adopted as future alternative for aphid management. However, detailed studies regarding understanding of underlying molecular mechanisms are needed to optimize the mode for field application.
Proverbs and Gender: The Interface between Proverbs and Human Relations in a Refugee Camp

The primary objective of this presentation is to understand how proverbs reflect society's perception of gender in a particular socio-cultural context. This qualitative study recognizes the direct experiences and insights of the 35 participants on gender relations. The proverbs provided by the participants led us to an in-depth analysis of the attitude of men toward women and their assumption of women’s role in a patriarchal society which could influence the gender relationship among Sri Lankan Tamils inside Indian refugee camps. A conceptual framework was developed to aid understanding of the research findings and illustrate the interrelationship between (a) refugee camps, (b) socio-cultural context, (c) patriarchal, and (d) collective identity. This framework provides an opportunity to position proverbs in a unique context. This study identified that the proverbs validate cultural expressions, justify rituals and gender practices, impose social pressure and social control on women, and reinforce society’s moral principles and values.
Empirical Study on the Acceptance of Mobility as a Service (MaaS) Based on the UTAUT2 Model

To achieve the widespread use of Mobility as a Service (MaaS), a novel transportation platform, it is important to increase consumers' intention to use MaaS. Therefore, this study clarifies the determinants of consumers’ intention to use MaaS based on the UTAUT2 model. The research model is tested using structural equation modeling based on data from a web-based questionnaire survey of Japanese consumers. The results show that performance expectancy, social influence, hedonic motivation, and price value have significant effects on the intention to use MaaS. Moreover, the relationship between the intention to use MaaS and independent variables is moderated by old age. Theoretical and practical implications are discussed based on the findings.
Thermal modulation for suppression of parametric instability in advanced gravitational wave detectors

Three-mode parametric instability is a threat to attaining design power levels in advanced gravitational wave detectors. The first observation of three-mode parametric instability in a long optical cavity revealed that instabilities could be suppressed by time variation of the mirror radius of curvature. In this paper, we present three dimensional finite element analysis of this thermo-acousto-optics system to determine whether thermal modulation could provide sufficient instability suppression without degrading time averaged optical performance. It is shown that deformations due to the time averaged heating profile on the mirror surface can be compensated by rear surface heating of the test mass. Results show that a heating source with a modulation amplitude of 1 W at 0.01 Hz is sufficient to stabilize an acoustic mode with parametric gain up to 3. The parametric gain suppression factor is linearly proportional to the peak modulation power.
