Parenting Practices and Adolescents’ Mental Health: The Mediating Role of Perceived Maternal and Paternal Acceptance-Rejection and Adolescents’ Self-Efficacy

Parenting practices are essential in promoting children’s mental health, especially in effective and ineffective parenting. The use of ineffective parenting practices is no longer encouraged in the west; however, it remains a common practice among Asian households. Ineffective parenting consists of inconsistent discipline, corporal punishment, and poor monitoring which may result in mental health consequences. Thus, this study assessed the mediating effects of adolescents’ self-efficacy and parental acceptance-rejection on the relationship between ineffective parenting practices and adolescents’ mental health. The current study involved a total of 761 school-going Malaysian adolescents aged 13–18 (38.5% males; Mage = 15.65; SDage = 1.43). This study utilized a cross-sectional design where it measured adolescents’ mental health, ineffective parenting practices, parental acceptance-rejection, and adolescents’ self-efficacy. Both paternal and maternal parenting practices and acceptance-rejection were measured independently. Adolescents’ self-efficacy and perceived paternal and maternal acceptance-rejection were found to be significant mediators for ineffective parenting practices and adolescents’ mental health. Our findings suggest that ineffective parenting practices will result in perceived parental rejection and lower self-efficacy which in turn resulted in poorer mental health among adolescents. It means parents should be mindful of their parenting approaches as they have a direct and indirect impact on the mental health of their offspring.

Sensitivity of transition phenomena to small perturbations in flow round a circular cylinder

In the critical Reynolds-number range (Re = 3−4 × 105) the structure of the flow around a circular cylinder undergoes drastic changes that are coupled with a break in symmetry manifested by the occurrence of a steady lift force having unpredictable sign. Between the stable states the time functions of lift exhibit chaotic behaviour. Sensitivity to small perturbations is demonstrated by experiments showing that in principle it is possible to trip all transition jumps in the critical range by a perturbation localized in space and time. The structural changes of the flow, in particular the symmetry breaks, are visualized by oil-flow photographs. Furthermore the transition jumps were recorded in the time domain, thus the characteristic time for the jumps was obtained.
Hepatitis B and C infections among lymphoma patients: a national study in the Republic of Moldova.

INTRODUCTION Hepatitis B virus (HBV) and hepatitis C virus (HCV) represent common infections that are presumably associated with various types of lymphoma and specific clinical features. However, conclusive data are lacking and results from different regional studies are conflicting. Hence, a national study was performed in order to investigate potential associations between hepatitis infections and lymphoma in the Republic of Moldova. METHODOLOGY Data were collected from newly diagnosed adult lymphoma patients from January 2020 to January 2022. Patients who were not tested for HBsAg and anti-HCV and those with an undetermined lymphoma subtype diagnosis were excluded from the study. Subjects with and without viral hepatitis were then evaluated on the basis of clinical and pathological characteristics. RESULTS One hundred and twenty-nine lymphoma patients were included in the study; 15 (11.6%) patients were diagnosed with hepatitis B, 21 (16.3%) patients with hepatitis C, and 1 (0.78%) patient was positive for both. The majority of hepatitis patients were over 60 years old (62.2%), presented with stage III or IV (81%), had normal lactate dehydrogenase (58.3%) and 0 or 1 extranodal sites (78.4%). The most common lymphoma subtypes were diffuse large B-cell lymphoma (64.9%) and marginal zone lymphoma (8.1%). We did not find any statistically significant differences between infected and uninfected lymphoma patients in regards to clinical features, specific lymphoma subtypes, and presence and location of extranodal involvement. CONCLUSIONS Presence of hepatitis B or C virus infections is not associated with specific clinical and pathological features in Moldovan lymphoma patients.
Measurement of Force and Intramuscular Pressure Changes Related to Thrust Spinal Manipulation in an In Vivo Animal Model

Simple Summary Spinal manipulation is recommended by clinical guidelines to treat low back pain. However, our understanding of how spinal manipulation alleviates pain and knowledge of the role that viscoelastic tissue properties play in the dampening of applied spinal manipulation forces in vivo is limited. Superficial and deep intramuscular pressures and applied forces were measured using miniature pressure catheters and a force transducer during low back spinal manipulation using a clinically available spinal manipulation device (Activator V) or a feedback motor in a deeply anesthetized animal model. Viscoelastic properties of muscle and other soft tissues greatly diminished applied spinal manipulative forces as well as intramuscular pressures in deep spinal tissues. These animal model findings may eventually have clinical implications or help to determine how spinal manipulation helps to alleviate muscular low back pain, particularly if it is determined that certain thresholds of deep tissue forces or intramuscular pressure changes are required to initiate a cascade of biological mechanisms resulting in a positive clinical treatment response. Abstract Current knowledge regarding biomechanical in vivo deep tissue measures related to spinal manipulation remain somewhat limited. More in vivo animal studies are needed to better understand the effects viscoelastic tissue properties (i.e., dampening) have on applied spinal manipulation forces. This new knowledge may eventually help to determine whether positive clinical outcomes are associated with particular force thresholds reaching superficial and/or deep spinal tissues. A computer-controlled feedback motor and a modified Activator V device with a dynamic load cell attached were used to deliver thrust spinal manipulations at various magnitudes to the L7 spinous process in deeply anesthetized animals. Miniature pressure catheters (Millar SPR-1000) were inserted unilaterally into superficial and deep multifidi muscles. Measurements of applied mechanical forces and superficial/deep multifidi intramuscular pressure changes were recorded during spinal manipulations delivered in vivo. Manipulative forces and net changes in intramuscular pressures reaching deep spinal tissues are greatly diminished by viscoelastic properties of in vivo tissues, which could have possible clinical safety and/or mechanistic implications.
Hybrid conjugated polymer solar cells using patterned GaAs nanopillars

In this work, we study hybrid solar cells based on poly(3-hexylthiophene)-coated GaAs nanopillars grown on a patterned GaAs substrate using selective-area metal organic chemical vapor deposition. The hybrid solar cells show extremely low leakage currents (I≅45 nA @−1V) under dark conditions and an open circuit voltage, short circuit current density, and fill factor of 0.2 V, 8.7 mA/cm2, and 32%, respectively, giving a power conversion efficiency of η=0.6% under AM 1.5 G illumination. Surface passivation of the GaAs results in further improvement, yielding η=1.44% under AM 1.5 G illumination. External quantum efficiency measurements of these polymer/inorganic solar cells are also presented.
An Improved Finite Temperature Lanczos Method and Its Application to the Spin-1/2 Heisenberg Model on the Kagome Lattice

We present an improvement of the finite temperature Lanczos method in order to apply this method to systems at very low temperature. One proposal is to introduce two steps in this method. In the first step, we use the Chebyshev polynomial expansion to calculate exp(-H/T1) random vector> at moderate temperature T1. In the second step, we apply the ordinary finite temperature Lanczos method using the calculated state as the initial state of the Lanczos method. Another proposal is to employ a sampling method for selecting a random vector. By this sampling, we can improve an efficiency of calculations. Using the improved finite temperature Lanczos method, we calculate the specific heat of the spin-1/2 Heisenberg model on the kagome lattices of 27 and 30 sites.
Microstructural and antibacterial properties of zinc-substituted cobalt ferrite nanopowders synthesized by sol-gel methods

Zinc-substituted cobalt ferrite nanopowders were prepared via a sol-gel route using citric acid as a chelating agent. The influence of zinc concentration on the microstructure, crystal structure, surface wettability, surface roughness, and antibacterial property of zinc-substituted cobalt ferrite nanopowders was investigated systematically. The substitution of zinc influences slightly the microstructure, surface wettability, surface roughness, and crystal structure but strongly affects the antibacterial property of the cobalt ferrite nanopowders.
Normal-Knowledge-Based Pavement Defect Segmentation Using Relevance-Aware and Cross-Reasoning Mechanisms

Automatic pavement defect segmentation is a big challenge because of the class diversity and extremely random distribution of defects. Most existing approaches focus on supervised strategies to achieve decent performance. Due to the difficulty of getting massive densely annotated samples and the limited prior knowledge of potential defects, these methods have significant bottlenecks in the actual pavement settings. This paper proposes a relevance-aware and cross-reasoning network (RCN) for anomaly segmentation of pavement defects, which can segment defects using merely non-defective images for training. A relevance-aware transformer-based encoder is first devised to model intrinsic interdependencies across local features, thus improving representations of complex non-defective images. Next, a dual decoder strategy is proposed to remap the encoder-generated latent dependencies at the local semantic and global detailed levels, respectively. Specifically, a cross-reasoning refinement module is built in the local decoder to reason the cross-relationship between spatial and channel dimensions. Finally, a context-aware abnormal distillation measurement is developed to evaluate the semantic reconstruction deviations during the inference. Under the guidance of semantic affinity, this measurement allows our model to highlight defective areas adaptively. Extensive experimental results on four datasets indicate that RCN outperforms other leading anomaly segmentation methods.
Effects of Paclitaxel Exposure on Food Intake and Body Weight Gain in Adult Rats

For the therapeutic management of various types of cancer, paclitaxel (PTX) is commonly used for chemotherapy. Peripheral neuropathy, neuropathic pain, behavioral changes and emotional depression are all side effects of PTX therapy, but their effect on food consumption and body weight gain in adult patient have not been well reported so far. Therefore, present study aimed to evaluate the impact of PTX on food consumption and body weight gain in adult female Wistar rats. In this study, selected equivalent therapeutic doses of PTX (1.6 and 3.2 mg/kg bw) were administered intermittently for six weeks (once a week) intravenously in tail vein via catheter. During experiment, food consumption and body weight of PTX exposed and control rats were recorded. During six weeks of intermittent exposure, our results revealed dose-dependent substantial reduction in food consumption and body weight except first week of PTX exposure in adult Wistar female rats. The effect of equivalent therapeutic doses of PTX was found to be associated with feeding pattern (anorexia) and body weight loss (body mass index) involving multifactorial regulatory mechanisms for controlling the food consumption and body weight changes.
Alignment sensitivity of molecular-frame photoelectron momentum and angular distribution of H2+ by XUV attosecond pulses

In this work, we investigate the molecular-frame photoelectron momentum and angular distributions (MF-PMD and MF-PAD) of H2+ in the presence of XUV Attosecond Pulses. We present the alignment-sensitive effect of MF-PMDs and MF-PADs when the laser field polarization and the molecular axis are close to parallel geometry. Our results show that the MF-PADs and MF-PMDs of single-photon ionization of H2+ ion vary drastically when the alignment slightly shifts from parallel geometry to a small alignment angle (e.g. 4°) between the laser polarization direction and the molecular axis at the equilibrium inter-nuclear distance of R c = 2 atomic units. As R c increases to 4 atomic units, such sensitivity is decreased. The R c -dependent transition cross-sections in different channels are found to be the origin of such sensitivity.
Gravity wave radiation from vortex trains in rotating shallow water

Gravity wave radiation by vortical flows in the f-plane shallow-water equations is investigated by direct nonlinear numerical simulation. The flows considered are initially parallel flows, consisting of a single strip in which the potential vorticity differs from the background value. The flows are unstable to the barotropic instability mechanism, and roll up into a train of vortices. During the subsequent evolution of the vortex train, gravity waves are radiated. In the limit of small Froude number, the gravity wave radiation is compared with that predicted by an appropriately modified version of the Lighthill theory of aerodynamic sound generation. It is found that the gravity wave field agrees well with that predicted by the theory, provided typical lengthscales of vortical motions are well within one deformation radius. It is found that the nutation time for vortices in the train increases rapidly with increasing Froude number in cases where the potential vorticity in the vortices is of the same sign as the background value, whereas the nutation time is almost independent of Froude number in cases where the potential vorticity in the vortices is zero or of opposite sign to the background. Consequently, in the former cases, the unsteadiness of the flow decreases with increasing Froude number, so the effect of the inertial cutoff frequency is increased, leading to an optimal Froude number for gravity wave radiation, above which the intensity of the radiated waves decreases as the Froude number is further increased. It is proposed that the existence of a finite range of interaction within the vortices, for flows with positive vortex potential vorticity, may account for the strong dependence of nutation time on Froude number in those cases. The interaction scale within the vortices becomes infinite in the limit of zero vortex potential vorticity, and so the arguments do not apply in those cases.
Gravitational collapse in molecular cloud cores around ultracompact H II regions - two candidates

Observations of NH3(1, 1) obtained with 10-arcsec resolution in the molecular cores surrounding two ultracompact H II regions, W3(OH) and G34.3+0.2, are reported. Both sources show extended emission components with velocity gradients consistent with rotation and absorption components that are redshifted with respect to the emission, suggesting gravitational infall. The velocity structure in both sources, and the density and temperature structure in W3(OH), appear similar to that around the previously observed H II region, G10.6-0.4, which is well modeled by a centrally condensed, and centrally heated, molecular core gravitationally collapsing onto the H II region. It is suggested that velocity and temperature structures similar to those seen in W3(OH), G34.3+0.2, and G10.6-0.4 may be a useful signature of gravitational collapse. 34 references.
Using patients’ stated preferences for immunoglobulin therapies to evaluate administration features in current treatments

In 2012, Mohamed et al.(J Med Econ) estimated preference weights for changes in the administration features of immunoglobulin (IG) therapies among patients with self-reported primary immunodeficiency disorder (PIDD). The preference weights were estimated using a discrete-choice experiment survey that asked respondents to choose between hypothetical treatments with varying administration features. However, the authors did not discuss the implications of their results on patients’ preferences for currently available IG therapies with specific combinations of the elicited features. Transferring preference results from Mohamed et al. allowed us to evaluate current treatment options not considered during the original study. This transfer of preference information is commonplace in economics, but not in health applications where it is done almost exclusively with treatment outcomes and not treatment administration features. The aim of this study was to assess patients’ relative preferences for currently available IG treatments in terms of their administration features as elicited by Mohamed et al. To achieve this objective, we approximated a preference-weight function through visual examination of the weights plotted in the publication. This function provides a calculation of preference scores for any IG treatment described with the attributes studied in Mohamed et al. This research suggests a general tendency in PIDD patients to prefer the administration features associated with intravenous therapies over subcutaneous therapies. The evaluation of IG therapies with the approximated preference function highlights how attribute preferences can be considered jointly in clinically meaningful treatment profiles.
3D numerical modelling of open-channel flow with submerged vegetation

Velocity distributions in channels partially covered with vegetation have been computed using a three dimensional model. The Navier-Stokes equations were solved, using the SIMPLE method and the k-ε turbulence model. The vegetation was modeled as vertical cylinders. A formula for the drag force on the vegetation was included as a sink term in the Navier-Stokes equations. The advantage with this method compared with using large roughness is that effects of the vegetation over the whole water depth can be taken into account, instead of only affecting the velocity near the bed. The numerical model was tested against three laboratory experiments from straight flumes with uniform flow, where vegetation partially covered the cross-section. The velocity and vegetation density varied in both vertical and horizontal directions in the different cases. The experiments also included varying crosssectional shapes. All tests gave fairly good correspondence between computed and measured velocity profiles.
Predicting Consumers’ Intention to Shop Online in an Emerging Market: A COVID-19 Perspective

As an emerging economy, Bangladesh has witnessed a remarkable development in adopting information and communication technologies over the last decade. Hence, the fi eld of e-commerce is expanding rapidly and consumers are now using the internet as an alternative channel for buying. The fundamental purpose of this study is to predict consumers’ intention to purchase online during the COVID-19 pandemic in Bangladesh. Based on the Theory of Planned Behavior (TPB), this study attempts to explore certain factors (attitude towards online shopping, subjective norms, perceived behavioral control) aff ecting consumers’ online buying intention. A structured questionnaire has been used to collect the primary data through the CAWI survey method. A total of 157 respondents have participated in this study from diff erent universities in Sylhet city, Bangladesh. This study employed multiple regression analysis to test the proposed research model. The fi ndings indicate that all the predictors have a signifi cant impact on consumers’ behavioral intention to do online shopping during the COVID-19 pandemic. However, any developing country like Bangladesh has a genuine need for more research works on the e-commerce fi eld. This study provides some valuable insights into the adoption of the online shopping system in an emerging economy which helps the e-commerce industry to understand online consumers’ behavior to develop various marketing strategies accordingly. The study also contributes to the body of knowledge both at the academic and practical levels.
Alternative stability conditions for switched discrete time linear systems

Alternative necessary and sufficient conditions for absolute exponential stability are presented, for switched discrete–time linear systems. To reach these results, we exploit concepts from set theory and in specific the forward reachability set mappings. The developed theorem can be utilized to construct iterative numerical procedures for verifying stability. Two examples illustrate the effectiveness of the proposed methodology.
Voltage Harmonics Optimization for Weak Grid-Tied Doubly-Fed Induction Generator With the Capability of Suppressing Current Harmonics

Suppressing current harmonics is an essential capability of the grid-tied doubly-fed induction generator (DFIG). For the weak grid tied DFIG, the suppression of current harmonics is accompanied by the compromise of voltage harmonics at the point of common coupling (PCC). Currently, the effect of current harmonic suppression is the focused concern. But, the potential of voltage quality optimization is neglected. The key to solving this issue is to find the reconcilability of the conflict between the current quality and voltage quality. Therefore, this paper firstly analyzes the coupling relationship between voltage harmonics and current harmonics at PCC from the perspective of harmonic impedance, and then investigates the optimal harmonic impedance of weak grid tied DFIG, which sacrifices minimum voltage quality to achieve current harmonics suppression. Further, a self-regulated harmonic impedance reshaping for DFIG based on the optimal harmonic impedance design is proposed. The proposed method can adaptively reshape the DFIG impedance to be optimal under different grid conditions. The theoretical analysis and experimental results are done to verify the correctness of the optimal harmonics impedance theory and the validity of the proposed control strategy.
