Parenting style and children emotion management skills among Chinese children aged 3–6: the chain mediation effect of self-control and peer interactions

Drawing on ecosystem theory, which is based on the interaction of family environment, individual characteristics, and social adaptation, this study aimed to examine the effects of parenting style on emotion management skills and the mediating roles of self-control and peer interactions among Chinese children aged 3–6 years. Some studies have investigated the relationship between parenting style and emotion management skills. However, research on the underlying mechanisms is still deficient. A sample of 2,303 Chinese children completed the PSDQ-Short Version, the Self-Control Teacher Rating Questionnaire, the Peer Interaction Skills Scale, and the Emotion Management Skills Questionnaire. The results show that: (1) Authoritarian parenting style negatively predicted children’s emotion management skills, self-control, and peer interactions; (2) Authoritative parenting style positively predicted children’s emotion management skills, self-control, and peer interactions; (3) Structural equation models indicated that self-control and peer interactions partially mediated the effects of authoritarian and authoritative parenting styles. The parenting style of Chinese children aged 3–6 years is related to emotion management skills, and self-control and peer interactions have chain mediating effects between parenting style and children’s emotion management skills. These results provide further guidance for the prevention and intervention of emotional and mental health problems in children.
Distributed Real-time Optimal Power Flow Strategy for DC Microgrid Under Stochastic Communication Networks

This paper addresses a distributed real-time opti‐ mal power flow (RTOPF) strategy for DC microgrids. In this paper, we focus on the scenarios where local information shar‐ ing is conducted in stochastic communication networks subject to random failures. Most existing real-time optimal power flow (OPF) algorithms for the DC microgrid require all controllers to work in concert with a fixed network topology to maintain a zero gap between estimated global constraint violations. Thus, the high reliability of communication is required to ensure their convergence. To address this issue, the proposed RTOPF strate‐ gy tolerates stochastic communication failures and can seek the optimum with a constant step size considering the operation limitations of the microgrid. These aspects make the strategy suitable for real-time optimization, particularly when the com‐ munication is not reliable. In addition, this strategy does not re‐ quire information from non-dispatchable devices, thereby reduc‐ ing the number of sensors and controllers in the system. The convergence of the proposed strategy and the optimal equilibri‐ um points are theoretically proven. Finally, simulations of a 30bus DC microgrid are performed to validate the effectiveness of the proposed designs.
Comparative Studies on Quality Changes of Air Blast and Plate Frozen Mackerel (Rastrelliger kanagurta) During Frozen Storage

Mackerel ( Rastrelliger kanagurta Cuvier ) frozen in commercial plate and air blast freezers were studied to compare the quality changes during frozen storage (-180C)/ The frozen fish were sealed in polythene bags of food grade Linear Low Density Polyethylene (LLDPE), 120 gauge thick conforming to IS: 9845 - 1981) then packed in 5-ply corrugated fiberboard carton and were analyzed for changes in quality during storage at -180C. The moisture and protein content in air blast frozen samples were decreased (p 0.05) in PV of both the samples. TBA of air blast frozen samples showed an increasing trend (p 0.05). The TMA-N and TVB-N of both the samples showed an increasing trend but air blast frozen samples showed little higher values (p<0.05) than plate frozen samples. The total plate count decreased significantly (p<0.05) in both the samples. The samples frozen in plate freezer were established to be superior (p<0.05) compared to air blast freezer with regard to sensory attributes like appearance, odour etc., and overall acceptability. The present study indicated that plate frozen samples were slightly better than air blast frozen samples in quality because of quick freezing effect but mackerel frozen by both plate and air blast freezer were acceptable even after 3 months of storage at -18°C.
Differential frequency-dependent delay from the pulsar magnetosphere

Some radio pulsars show clear 'drifting subpulses', in which subpulses are seen to drift in pulse longitude in a systematic pattern. Here we examine how the drifting subpulses of PSR B0809+74 evolve with time and observing frequency. We show that the subpulse period (P3) is constant on timescales of days, months and years, and between 14-5100 MHz. Despite this, the shapes of the dn´ftbands change radically with frequency. Previous studies have concluded that, while the subpulses appear to move through the pulse window approximately linearly at low frequencies ( 820 MHz) near to the peak of the average pulse profile. We use LOFAR, GMRT, GBT, WSRT and Effelsberg 100-m data to explore the frequency-dependence of this phase step. We show that the size of the subpulse phase step increases gradually, and is observable even at low frequencies. We attribute the subpulse phase step to the presence of two separate driftbands, whose relative arrival times vary with frequency - one driftband arriving 30 pulses earlier at 20 MHz than it does at 1380 MHz, whilst the other arrives simultaneously at all frequencies. The drifting pattern which is observed here cannot be explained by either the rotating carousel model or the surface oscillation model, and could provide new insight into the physical processes happening within the pulsar magnetosphere.
Impact of fly ash/pond ash in vertisols on long term basis vis-à-vis on grain yield of sunflower and maize and status of heavy metals and activity of radio nuclides in soil.

In India too, much increasingly R & D work is being directed in recent years on the application of fly ash in agriculture sector. Fly ash, being rich in nutrients and of pozzolanic character, offered good potential for agriculture. At College of Agriculture, Raichur, Karnataka, a systematic and in-depth studies on the utilization of fly ash in agriculture sector under various soil types and in varying agro-climatic conditions have been carried out over the past one and half decade, where it has been rather well established that fly ash can be advantageously used in agriculture as soil conditioner, source of essential plant nutrients, in improving important physico-chemical properties of the soil and boosting the crop growth and yields of a variety of crops and for reclamation of waste/degraded lands etc. In a sequel to the studies made on long term basis (2004-06) for cultivation of sunflower and maize in irrigated vertisols in rotation, keeping the following objectives in view: (i) Safe disposal and gainful bulk utilization of fly ash/ pond ash generated from RSTPS, Shaktinagar. (iii) Study of its effect on growth and yields of various crops specific to this region including the effects on heavy metal status and activity of radionuclides of soil. MATERIALS AND METHODS Soil : Field experiments were carried out on irrigated vertisol belonging to the Raichur series of Typic Haplustert. Composite soil samples collected from the experimental site before the start of experiments were analyzed for various parameters by adopting standard methods (Table 1). The soil was clay in texture, alkaline in reaction (pH 8.6), low in soluble salt content (0.1 dS/m) and high in organic carbon, available nitrogen and potassium contents. The DTPA extractable Cu, Fe, Mn and Zn content were 1.59, 2.17, 8.13 and 0.90 mg/kg of soil, respectively. The total lead, arsenic and selenium contents were 13.9, 1.2 and 0.9 mg/kg of soil. Field experiments were conducted at Agricultural College Farm, Raichur, Karnataka from 2004 to 2006. Raichur is located in the North Eastern Dry Zone (Zone-1) of Karnataka between 16 15’ N latitude 77020’ E longitudes and at an altitude of 389 meters above mean sea level (MSL).
From spintronics to Majorana bound states.

Spin-valve structures in which a change of magnetic configuration is responsible for magnetoresistance have enabled impressive advances in spintronics, focusing on magnetically storing and sensing information. However, this mature technology also offers versatile control of the underlying fringing fields and entirely different applications by realizing topologically-nontrivial states. Together with proximity-induced superconductivity in a two-dimensional electron gas, these fringing fields realized in commercially-available spin valves could control Majorana bound states (MBS). Detailed support for the existence and control of MBS is obtained by combining accurate micromagnetic simulation of fringing fields used as an input in Bogoliubov de Gennes equation to calculate low-energy spectrum, wavefunction localization, and local charge neutrality. A generalized condition for quantum phase transition in these structures provides valuable guidance for the MBS evolution and implementing reconfigurable effective topological wires.
ANTIBIOTIC SUSCEPTIBILITY PROFILES OF STAPHYLOCOCCUS AUREUS IN HOSPITAL ANGKATAN TENTERA TUANKU MIZAN (HATTM), MALAYSIA: A PRELIMINARY STUDY

Background: Staphylococcus aureus is a human pathogen causing a variety of diseases ranging from superficial skin and soft-tissue infections to life-threatening infections. Nowadays, the treatment has become complicated due to the emergence of methicillin-resistant S. aureus (MRSA). It is an established pathogen that causes hospital- and community-acquired infections worldwide. This study was a preliminary retrospective study involving S. aureus clinical isolates from Hospital Angkatan Tentera Tuanku Mizan (HATTM) for a period of 6 months (October 2018 until March 2019). Objectives: The study was conducted to determine the S. aureus antibiotic susceptibility profiles and its association with types of infection, gender, wards, age of patients and types of specimens. Methods: Standard bacteriological method was used for S. aureus isolation from various clinical specimens including blood, urine, pus and wound, eye, throat, nasal, pericardial fluid, tracheal aspirate, high vagina swab (HVS), bronchial alveolar lavage (BAL) and tissue. Kirby-Bauer disc diffusion method was utilized for antibiotic susceptibility profiles determination. Results: Ninety-five S. aureus strains were isolated from 3571 specimens. Twenty-six of the isolates (27%) was identified as MRSA and 69 (73%) was identified as methicillin-sensitive S. aureus (MSSA). Among the MRSA, 4 isolates were hospital-acquired MRSA (HA-MRSA) and the rest were community-acquired MRSA (CA-MRSA). There was a statistically significant association between isolation of MRSA with age of patient as well as types of infection or origin of the MRSA (p<0.05). Only 42 (44.2%) of the S. aureus isolates were fully susceptible to all antibiotics. Almost half isolates (n=46, 48.4%) were resistant to at least two antibiotics and seven (7.4%) isolates were resistant to one type of antibiotic only. Conclusions: None of the isolate showed reduced susceptibility nor resistant to vancomycin. Future study with a larger sample size using a wider study period needs to be done to confirm that vancomycin-resistant S. aureus has not yet been established in HATTM.
Online learning during the COVID-19 era: the antecedents of continuance intention and communication channel satisfaction from learners’ perspective

ABSTRACT Building on the Flow theory and Stimulus-Organism-Response framework, this study investigates the impact of online platforms’ technological environment and communicator competence on learners’ continuance intentions and communication channel satisfaction mediated by virtual experience. Data collected from undergraduate and postgraduate students in North Cyprus and Lithuania were used to assess the proposed relationships utilizing structural equation modeling. The results indicated that the platforms’ technological environment has a significant impact on virtual experience while the communicator competence has a significant impact on learners’ virtual experience in the Lithuanian context only. Moreover, the findings revealed that virtual experience has a significant impact on learners’ continuance intention and communication channel satisfaction. Furthermore, the results indicated that virtual experience mediates the relationship between the technological environment and learners’ continuance intention and communication channel satisfaction in both contexts; however, virtual experience mediates the relationship between communicator competence and learners’ responses in the Lithuanian context only.
Consistent Generative Query Networks

Stochastic video prediction models take in a sequence of image frames, and generate a sequence of consecutive future image frames. These models typically generate future frames in an autoregressive fashion, which is slow and requires the input and output frames to be consecutive. We introduce a model that overcomes these drawbacks by generating a latent representation from an arbitrary set of frames that can then be used to simultaneously and efficiently sample temporally consistent frames at arbitrary time-points. For example, our model can “jump” and directly sample frames at the end of the video, without sampling intermediate frames. Synthetic video evaluations confirm substantial gains in speed and functionality without loss in fidelity. We also apply our framework to a 3D scene reconstruction dataset. Here, our model is conditioned on camera location and can sample consistent sets of images for what an occluded region of a 3D scene might look like, even if there are multiple possibilities for what that region might contain.

Bone histology and growth of chasmosaurine ceratopsid dinosaurs from the Late Campanian Kaiparowits Formation, southern Utah

Ceratopsian dinosaurs are one of the most diverse dinosaur groups in the Cretaceous, and an outstanding question is how growth strategies of this group evolved in relation to their shift from small bipedal basal ceratopsians to larger quadrupedal ceratopsids. Previous bone histology studies have investigated several basal ceratopsians and centrosaurine ceratopsids (e.g., Centrosaurus, Pachyrhinosaurus, Einiosaurus), but no chasmosaurine ceratopsids have been investigated. I conducted histological analysis of humeri, ulnae, femora, tibiae, ribs, and ossified tendons from multiple specimens of two species of chasmosaurine ceratopsid dinosaurs from the late Campanian (Upper Cretaceous) Kaiparowits Formation of southern Utah, Kosmoceratops richardsoni and Utahceratops gettyi, to examine bone microstructure indicators of growth rate and maturity. I also reexamined the long-bone histology of the ceratopsian dinosaurs Psittacosaurus mongoliensis, Protoceratops andrewsi, and Centrosaurus apertus. All elements of Utahceratops and Kosmoceratops examined are dominated by densely vascularized tissue, indicative of sustained fast growth. Radially-oriented vascular canals as well as dense osteocytes from throughout ontogeny are further indicators of rapid growth. I identified juvenile (UMNH VP 20444 & UMNH VP 20454), subadult (UMNH VP 16681) and adult (UMNH VP 16860, UMNH VP 16861, UMNH VP 12198) specimens of Utahceratops, and two subadult to adult specimens (UMNH VP 17000 & UMNH VP 21339) of Kosmoceratops. I conclude that basal ceratopsians grew more slowly than the large quadrupedal ceratopsids, as evidenced by a generally higher number of definitive growth lines prevalent throughout development. In contrast, the presence of dense osteocytes, and reticular and radially-oriented vascular canals are rapid growth indicators shared by all sampled large ceratopsids, and imply an elevated metabolism for all ceratopsians. Sampled specimens of Utahceratops and Kosmoceratops do not preserve any evidence of annual lines of arrested growth (LAGs). Placed in context with the number of LAGs observed in Alaskan Pachyrhinosaurus, Centrosaurus from Alberta, and Einosaurus from Montana, these data suggest a latitudinal gradient in the number of LAGs, which suggests that bone growth is reacting to the climate.
Utilization of a two-material decomposition from a single-source, dual-energy CT in acute traumatic vertebral fractures

Purpose The purpose of this study is to utilize a two-material decomposition to quantify bone marrow edema on a dual-energy computed tomography (DECT) scanner at the cervical, thoracic, and lumbar spine acute fractures in correlation with short tau inversion recovery (STIR) hyperintensity on magnetic resonance imaging (MRI) in comparison with the normal bone marrow. Materials and methods This retrospective institutional review board–approved study gathered patients over 18 years old who had acute cervical, thoracic, or lumbar spinal fractures scanned on a DECT scanner. Those who had a spinal MRI done with bone marrow STIR hyperintensity within 3 weeks of the DECT were included. The water (calcium) and fat (calcium) density (mg/cm3) measurements of the region of interest of the bone marrow were obtained at a normal anatomic equivalent site and at the fracture site where STIR hyperintensity was noted on MRI. A statistical analysis was performed using the paired t-test and Wilcoxon signed rank test (p > 0.05). Results A total of 20 patients met the inclusion criteria (males n = 17 males, females n = 3). A total of 32 fractures were analyzed: 19 cervical and 13 thoracolumbar. There were statistically significant differences in the water (43 ± 24 mg/cm3) and fat (36 ± 31 mg/cm3) density (mg/cm3) at the acute thoracic and lumbar spine fractures in correlation with edema on STIR images (both paired t-test <0.001, both Wilcoxon signed ranked test p < 0.01). There were no significant differences in the water (−10 ± 46 mg/cm3) or fat (+7 ± 50 mg/cm3) density (mg/cm3) at the cervical spine fractures. Conclusion The DECT two-material decomposition using water (calcium) and fat (calcium) analyses has the ability to quantify a bone marrow edema at the acute fracture site in the thoracic and lumbar spine.
Mesenchymal stem cell exosomes inhibit nucleus pulposus cell apoptosis via the miR-125b-5p/TRAF6/NF-κB pathway axis

Intervertebral disc degeneration (IVDD) is the pathological basis of a range of degenerative spinal diseases and is the primary cause of lower back pain. Mesenchymal stem cell (MSC) transplantation inhibits IVDD progression. However, the specific mechanisms that underlie these effects remain unclear. In this study, candidate microRNAs (miRNAs) are screened using bioinformatics and high-throughput sequencing. TNF-α is used to induce nucleus pulposus cell (NPC) degeneration. MSC-derived exosomes (MSC-exosomes) are obtained using high-speed centrifugation and identified by transmission electron microscopy (TEM), nanoparticle tracking analysis (NTA) and western blot analysis. Cell viability is determined by CCK-8 assay. Flow cytometry and TUNEL assays are used to detect cell apoptosis. The expression levels of miR-125b-5p are detected by RT-qPCR, and a dual-luciferase gene reporter assay confirms the downstream target genes of miR-125b-5p. Protein expression is determined by western blot analysis. Rat models are used to validate the function of miR-125b-5p in MSC-exosomes. The results show that miR-125b-5p is expressed at low levels in degenerated disc tissues compared with that in normal disc tissues; however, it is highly expressed in MSC-exosomes. Furthermore, MSC-exosomes are efficiently taken up by NPCs while miR-125b-5p is delivered into NPCs; thus, MSC-exosomes act as inhibitors of apoptosis in NPCs. Overexpression of miR-125b-5p downregulates TRAF6 expression and inhibits NF-κB activation. However, TRAF6 overexpression reverses these effects of miR-125b-5p. We demonstrate that MSC-exosomes attenuate IVDD in vivo by delivering miR-125b-5p. MSC-exosomes can deliver miR-125b-5p to target TRAF6, inhibit NF-κB activation, and attenuate the progression of IVDD.
Fishery, stock assessment and management of the barracuda resource in India

The annual landings of barracuda increased from 1996 t in 1969 to 14679 t in 1995. During 1985-93 on an average 8332 I was landed and it constituted 0.44% oj the total marine fish catch, in India. The statewise contribution was Tamilnadu 3925 t (47.7%), Kerala 2471 t (30.0%), Andhra Pradesh 457 t (5.6%), Gujarat 420 t (5.1%). Maharashtra 416 t (5.0%), Karnataka 340 t (4.1%,), Pondicherry 98 i (1.2%), Orissa 71 t (0.9%) and Goa 29 t (0.4%>j. Four species Sphyraena obtusata, S.Jello, S. picuda and S.Jorsieri sustained the barracuda fishery in India. The growth paralmeters like Loa K, to: length weight relationships and natural mortality of S. obtusata S.Jello and S. picuda have been calculated The total mortality rate, fishing mortality rate generated by the trawl and drift gillnets and stock have been estimated for these three species. At present S. obtusata is under exploited by trawlnet and S.Jello and S. picuda are exposed to high fishing pressure by drift gillnets. The production may be increased by intensifying the exploitation in the deeper waters beyond 100 m depth. Suggestions and recommendations for proper management of the fishery have been proposed
Finiteness of steady state plumes

The finite maximum length of a steady state contaminant plume is determined by developing and employing a new analytical solution which overcomes two drawbacks associated with existing approaches. First, we account for a sharp front caused by the complete consumption of the pollutant (“electron donor”) and some electron acceptor in an instantaneous binary reaction occurring at the front. This approach is not based on purely conservative or first‐order degradation models which lead to theoretically infinite plumes and, in addition, depend on a concentration threshold. Second, a vertical aquifer cross section with finite thickness is selected as a model in order to better represent the supply of electron acceptors mostly entering the aquifer from the top. This type of setting allows investigation of the impact of aquifer thickness on plume length. An implicit representation of the donor‐acceptor front in a finite vertical domain previously required numerical solutions of the underlying advection‐dispersion‐reaction equation; we provide for the first time an analytical solution of this two‐dimensional transport problem. The length of the plume is found to be given by the point of intersection of the donor‐acceptor front and the aquifer bottom. Furthermore, a rather simple and highly accurate approximation is derived to compute the steady state plume length. A comprehensive sensitivity analysis reveals that results are most strongly influenced by aquifer thickness, followed by vertical transverse dispersivity and, to a somewhat lesser extent, by chemical reaction parameters. Longitudinal dispersivity has practically no effect on plume length, and furthermore, there is zero impact of linear velocity. With regard to groundwater risk assessment at the field scale it is also important to note that the present approach is meant to provide an upper bound on the actual plume length. Further research activities may be directed to refine the transport model by considering, for instance, degradation inside the plume and the limited vertical extent of the contaminant source.
