Psychometric properties of the Mongolian version of the Pittsburgh Sleep Quality Index

Poor sleep quality is associated with decreased brain health, such as fatigue, low quality of life, and risk of neurological and psychiatric comorbidities. Until now, no testing instruments for an accurate assessment of sleep quality for use in the general population have been rigorously translated and validated in Mongolia. We aimed to determine the psychometric properties of the globally recognized screening tool and sleep quality in the general population of Mongolia. In this cross-sectional study, participants were randomly selected between August and October 2020, from 64 sites in 8 urban, and 9 rural areas in Mongolia. Of the total 1152 participants (mean age, SD=42.66±12.6, range: 18 and 65) 76% were women. An overall Cronbach’s α was 0.69. Both EFA and CFA indicated a two-factor solution. The PSQI total score was positively correlated with anxiety and depression. The PSQI total score (p values < 0.01) was negatively correlated with the mean scores of all domains of WHOQOL-BREF. The mean PSQI total score was 5.67±3.4 and 43% of the participants were classified as poor sleepers by a global cut-off point of 5. The Mongolian version of the PSQI demonstrated a reliable and valid tool for screening sleep quality among the Mongolian general population. The results suggest that the prevalence rate of poor sleep quality was 43% using PSQI global cut-off point.
Morphological redescription and morphometry of Aniara sepulchralis (Coleoptera: Cicindelidae) from Northeast Para, Brazil

Aniara sepulchralis specimens sampled at different locations (Belém and Bragantina microregions) show differences in size of some morphological structures such as head width, pronotum width, distance between eyes, pronotum base width, labral length, labral width, and spur of the third pair of legs. These changes may be due to biotic, abiotic, and structural factors peculiar to each environment. Differences in structures and morphological measurements of males and females of Aniara sepulchralis were observed, characterized as sexual dimorphism in relation to their teeth and labral-clypeal suture. Females present apical teeth and rectilinear suture, whereas males present a more rounded shape in both teeth and the labral-clypeal suture. Regarding measurements, females have greater body length, head width, eye distance, pronotum length, pronotum width, labral length, and pronotum base width than males.
Effect of turbulent flow on an atmospheric-pressure AC powered gliding arc discharge

A high-power gliding arc (GA) discharge was generated in a turbulent air flow driven by a 35 kHz alternating current electric power supply. The effects of the flow rate on the characteristics of the GA discharge were investigated using combined optical and electrical diagnostics. Phenomenologically, the GA discharge exhibits two types of discharge, i.e., glow type and spark type, depending on the flow rates and input powers. The glow-type discharge, which has peak currents of hundreds of milliamperes, is sustained at low flow rates. The spark-type discharge, which is characterized by a sharp current spike of several amperes with duration of less than 1 μs, occurs more frequently as the flow rate increases. Higher input power can suppress spark-type discharges in moderate turbulence, but this effect becomes weak under high turbulent conditions. Physically, the transition between glow- and spark-type is initiated by the short cutting events and the local re-ignition events. Short cutting events occur owing to the twisting, wrinkling, and stretching of the plasma columns that are governed by the relatively large vortexes in the flow. Local re-ignition events, which are defined as re-ignition along plasma columns, are detected in strong turbulence due to increment of the impedance of the plasma column and consequently the internal electric field strength. It is suggested that the vortexes with length scales smaller than the size of the plasma can penetrate into the plasma column and promote mixing with surroundings to accelerate the energy dissipation. Therefore, the turbulent flow influences the GA discharges by ruling the short cutting events with relatively large vortexes and the local re-ignition events with small vortexes.A high-power gliding arc (GA) discharge was generated in a turbulent air flow driven by a 35 kHz alternating current electric power supply.

New insights into the therapeutic potentials of statins in cancer

The widespread clinical use of statins has contributed to significant reductions of cardiovascular morbidity and mortality. Increasing preclinical and epidemiological evidences have revealed that dyslipidemia is an important risk factor for carcinogenesis, invasion and metastasis, and that statins as powerful inhibitor of HMG-CoA reductase can exert prevention and intervention effects on cancers, and promote sensitivity to anti-cancer drugs. The anti-cancer mechanisms of statins include not only inhibition of cholesterol biosynthesis, but also their pleiotropic effects in modulating angiogenesis, apoptosis, autophagy, tumor metastasis, and tumor microenvironment. Moreover, recent clinical studies have provided growing insights into the therapeutic potentials of statins and the feasibility of combining statins with other anti-cancer agents. Here, we provide an updated review on the application potential of statins in cancer prevention and treatment and summarize the underneath mechanisms, with focuses on data from clinical studies.
Aging Mother–Adult Daughter Differentiation, Psychological Well-Being, and Parental Status

Despite the understanding that differentiation is a lifelong process crucial for psychological adaptation, there is limited knowledge regarding how parent–child differentiation in adulthood is associated with the psychological well-being of both parents and adult children. Furthermore, empirical research has yielded inconclusive results regarding whether the parental status of adult children influences the parent–child relationship. Consequently, the current study focuses on the moderating effect of adult daughters’ parental status on the association between aging mother–adult daughter differentiation and psychological well-being. The study utilized data from 167 pairs of Korean aging mothers and adult daughters to examine two main aspects: (1) the relationship between aging mother–adult daughter differentiation and psychological well-being; and (2) the moderating role of adult daughters’ parental status on the relationship between aging mother–adult daughter differentiation and psychological well-being. The findings revealed that both the differentiation of adult daughters and mothers was positively associated with their respective psychological well-being. However, no significant cross-interactional effects of aging mother–adult daughter differentiation on psychological well-being were observed. Notably, there was a positive moderating effect of the adult daughter’s parental status on the association between aging mother–adult daughter differentiation and psychological well-being for aging mothers.
Looking for the Ideal Probiotic Healing Regime

Wound healing is a multi-factorial response to tissue injury, aiming to restore tissue continuity. Numerous recent experimental and clinical studies clearly indicate that probiotics are applied topically to promote the wound-healing process. However, the precise mechanism by which they contribute to healing is not yet clear. Each strain appears to exert a distinctive, even multi-factorial action on different phases of the healing process. Given that a multi-probiotic formula exerts better results than a single strain, the pharmaceutical industry has embarked on a race for the production of a formulation containing a combination of probiotics capable of playing a role in all the phases of the healing process. Hence, the object of this review is to describe what is known to date of the distinctive mechanisms of each of the most studied probiotic strains in order to further facilitate research toward the development of combinations of strains and doses, covering the whole spectrum of healing. Eleven probiotic species have been analyzed, the only criterion of inclusion being a minimum of two published research articles.
Effects of Folklore Teaching with Constructivist and Computer-Assisted Teaching Method

In this study, the effects of constructivist learning and computer-assisted instruction on the achievement and attitudes of high school 2nd grade students in learning folk literature unit were examined by comparing with traditional teaching methods. The sample of the study consisted of 60 high school 2nd grade students studying in a high school in Arkalyk, Kazakhstan. The folk literature unit was taught by using constructivist learning and computer assisted instruction method in the experimental group, while traditional teaching methods were used in the control group. Constructivist teaching was organized according to the 5E model and associated with computer assisted instruction. The experimental applications of the research lasted 7 weeks. Folk literature achievement test and attitude scale towards folk literature were used to collect the data. As a result of the study, it was found that the students who studied with constructivist learning and computer-assisted instruction method achieved higher achievement levels in learning the folk literature unit compared to the students who studied with traditional teaching methods. The study also found out that constructivist learning and computer-assisted instruction practices significantly increased students' attitudes towards folk literature subjects.
Locomotion of a bioinspired flyer powered by one pair of pitching foils

We numerically investigate the flight dynamics and aerodynamics of a two-dimensional model for the jellyfishlike ornithopter recently devised by Ristroph and Childress [L. Ristroph and S. Childress, J. R. Soc. Interface 11, 20130992 (2014)]. This simplified model is composed of two rigid thin foils which are forced to pitch in antiphase fashion. The Navier-Stokes equations for the fluid and the dynamics equations for the flyer are solved together in the simulations. We first consider the constrained-flying condition where the flyer model is only allowed to move in the vertical direction. The influences of the control parameters on the hovering performance are studied. With the variations in parameter values, three different locomotion states, i.e., ascending, descending, and approximate hovering, are identified. The wake structures corresponding to these three locomotion states are explored. It is found that the approximate hovering state cannot persist due to the occurrence of wake symmetry breaking after long-time simulation. We then consider the free-flying condition where the motions in three degrees of freedom are allowed. We study the postural stability of a flyer, with its center of gravity located at the geometric center. The responses of the flyer at different locomotion states to physical and numerical perturbations are examined. Our results show that the ascending state is recoverable after the perturbation. The descending state is irrecoverable after the perturbation and a mixed fluttering and tumbling motion which resembles that of a falling card emerges. The approximate hovering state is also irrecoverable and it eventually transits to the ascending state after the perturbation. The research sheds light on the lift-producing mechanism and stability of the flyer and the results are helpful in guiding the design and optimization of the jellyfishlike flying machine.
EPIDEMIOLOGICAL AND CLINICAL IMPORTANCE OF CANINE DIOCTOPHIMOSIS

Dioctophimosis is an endoparasitism in dogs caused by Dioctophyma renale, a nematode with an indirect life cycle and high zoonotic potential. Infection in dogs occurs through ingestion of transitional/paratenic hosts containing infective larvae. The preferred site of parasitism is the right kidney, although the parasite may also be ectopically localized in subcutaneous tissue, internal organs, peritoneum, and mediastinum. Since dogs are usually infected with a small number of parasites, the disease is asymptomatic, making the diagnosis of this disease in clinical veterinary practice rather difficult. In addition, as dogs are usually infected with a small number of parasites, the disease is asymptomatic, which makes the diagnosing of this disease in clinical veterinary practice difficult. The long prepatent period, lasting three to five months, makes it impossible to diagnose the disease in dogs younger than six months. Clinical suspicion of dioctophimosis in dogs is established on the basis of anamnestic/epizootiologic data and the clinical picture, while the final diagnosis is made ante mortem or post mortem on the basis of reliable diagnostic parameters and methods. The most practical application in routine diagnosis of canine dioctophimosis is the detection of D. renale eggs in urine sediment. When dioctophimosis is suspected in carnivores, the differential diagnosis should exclude urinary capillariosis, feline polycystic nephropathy, leptospirosis, renal fibrosis, and nephritis of various etiology. The outcome of treatment is uncertain and includes surgical removal of the affected kidney or drug therapy with avermectin derivatives. Prophylaxis consists of preventing contact of dogs with potential transitional hosts and controlling the feeding of their heat-untreated meat. Because of the potential risks that D. renale may have on the health of dog owners, education on the etiopathogenesis and means of occurrence, maintenance, and spread of this nematode is necessary.
The yield of green phytomass of Siplhium perfoliatum L., newly-introduced energy crop tested on marginal heavy soils under Central European continental climate

This research was focused on a production potential of cup plant Silphium perfoliatum L. grown in marginal heavy soils with the following intensity of mineral nutrition: (i) intensive 245.0 kg/ha NPK, (ii) semi-intensive 122.5 kg/ha NPK and (iii) untreated control 0.0 kg/ha NPK. The large-scale pilot field experiments with ÓVÁRI-ÓRIÁS cultivar were carried out on 2 sites under semi-humid to humid Central European temperate climate during 4 years. Overall, it was achieved 13.59 t/ha of dry matter yield on average and the yields varied from 2.37 t/ha to 42.56 t/ha. During the three productive years (2018 – 2020) the crop yield was affected mainly by years (F-ratio 70.67, P-value 0.00), then by nutrition (F-ratio 30.50, P-value 0.00), followed by sites (F-ratio 1.92, P-value 0.17) and finally by replications (F-ratio 0.00, P-value 1.00). In general, cup plant productivity was increasing by a higher number of utility years and similarly, by increasing of nutrition intensity. Although the effect of the sites seems to be almost negligible, the present study does not include sites with arid or semi-arid climate, where the crop productivity may be completely different, especially if the soils are easy soils with an already drying water regime. This study focused on cup plant is probably one of first original research papers published as study based on large-scale experiments conducted in Slovakia, the crop is recognized as suitable perennial crop for energy as other purposes and therefore further agronomic as follow-up studies are needed.
Coincidence and common fixed point theorems for hybrid mappings

We prove common fixed point theorems for two pairs of hybrid mappings satisfying implicit relations in metric spaces using the concept of T−weak commutativity and we correct errors of [1], [4], [5] and [12]. Our Theorems generalize results of [1-5], [12] [16], [17-20] and [26].
Recovery of Transient High-Grade Atrioventricular Block Managed With Corticosteroid Therapy Without Device Implantation in Newly Diagnosed Cardiac Sarcoidosis: A Case Report

Atrioventricular blocks (AVBs) presenting in cardiac sarcoidosis (CS) remain an ongoing challenge for clinicians. While most initiate immunosuppressive therapy with the goal of pursuing device implantation, there is some ambiguity as to which patient cohorts actually benefit from device therapy. We present a case of a 39-year-old African American male with a past medical history of hypertension and no prior cardiac history who presented with substernal chest pain in the setting of a hypertensive emergency. He was later diagnosed with cardiac sarcoidosis by cardiac magnetic resonance imaging. His hospital course was complicated by transient Mobitz II atrioventricular block. He was started on prednisone, and while initially scheduled for an implantable cardioverter-defibrillator (ICD), his conduction block recovered. Through a multidisciplinary approach, the patient was discharged on medical management with outpatient follow-up. Since his initial hospitalization, the patient has not had any concerning cardiovascular events over the past year and has not been treated with device therapy. Our case illustrates the feasibility of effectively managing patients with cardiac sarcoidosis presenting with transient atrioventricular blocks only with corticosteroid therapy without needing device implantation.
Updated temperature correction for computing seawater nitrate with in situ ultraviolet spectrophotometer and submersible ultraviolet nitrate analyzer nitrate sensors

Sensors that use ultraviolet (UV) light absorption to measure nitrate in seawater at in situ temperatures require a correction to the calibration coefficients if the calibration and sample temperatures are not identical. This is mostly due to the bromide molecule, which absorbs more UV light as temperature increases. The current correction applied to in situ ultraviolet spectrophotometer (ISUS) and submersible ultraviolet nitrate analyzer (SUNA) nitrate sensors generally follows Sakamoto et al. (2009, Limnol. Oceanogr. Methods 7, 132–143). For waters warmer than the calibration temperature, this correction model can lead to a 1–2 μmol kg−1 positive bias in nitrate concentration. Here we present an updated correction model, which reduces this small but noticeable bias by at least 50%. This improved model is based on additional laboratory data and describes the temperature correction as an exponential function of wavelength and temperature difference from the calibration temperature. It is a better fit to the experimental data than the current model and the improvement is validated using two populations of nitrate profiles from Biogeochemical Argo floats navigating through tropical waters. One population is from floats equipped with ISUS sensors while the other arises from floats with SUNA sensors on board. Although this model can be applied to both ISUS and SUNA nitrate sensors, it should not be used for OPUS UV nitrate sensors at this time. This new approach is similar to that used for OPUS sensors (Nehir et al., 2021, Front. Mar. Sci. 8, 663800) with differing model coefficients. This difference suggests that there is an instrumental component to the temperature correction or that there are slight differences in experimental methodologies.
Extreme return, extreme volatility and investor sentiment

The extreme return and extreme volatility have great influences on the investor sentiment in stock market. However, few researchers have taken the phenomenon into consideration. In this paper, we first distinguish the extreme situations from non-extreme situations. Then we use the ordinary generalized least squares and quantile regression methods to estimate a linear regression model by applying the standardized AAII, the return and volatility of SP 500. The results indicate that, except for extremely negative return, other return sequences can cause great changes in investor sentiment, and non-extreme return plays a leading role in affecting the overall American investor sentiment. Extremely positive (negative) return can rapidly improve (further reduce) the level of investor sentiment when investors encounter extremely pessimistic situations. The impact gradually decreases with improvement of the sentiment until the situation turns optimistic. In addition, we find that extreme and non-extreme volatility cannot affect the overall investor sentiment.
Fixed b subsampling and the block bootstrap: improved confidence sets based on p‐value calibration

Summary. Subsampling and block‐based bootstrap methods have been used in a wide range of inference problems for time series. To accommodate the dependence, these resampling methods involve a bandwidth parameter, such as the subsampling window width and block size in the block‐based bootstrap. In empirical work, using different bandwidth parameters could lead to different inference results, but traditional first‐order asymptotic theory does not capture the choice of the bandwidth. We propose to adopt the fixed b approach, as advocated by Kiefer and Vogelsang in the heteroscedasticity–auto‐correlation robust testing context, to account for the influence of the bandwidth on inference. Under the fixed b asymptotic framework, we derive the asymptotic null distribution of the p‐values for subsampling and the moving block bootstrap, and further propose a calibration of the traditional small‐b‐based confidence intervals (regions or bands) and tests. Our treatment is fairly general as it includes both finite dimensional parameters and infinite dimensional parameters, such as the marginal distribution function. Simulation results show that the fixed b approach is more accurate than the traditional small b approach in terms of approximating the finite sample distribution, and that the calibrated confidence sets tend to have smaller coverage errors than the uncalibrated counterparts.
High precision gravitational self-force calculations and post-Newtonian implications

This talk is based on [1, 2, 3]. Until less than 10 years ago, post-Newtonian (PN) analysis was the only possible systematic method for obtaining gravitational waveforms corresponding to binary inspiral. However, these were cut-off before the merger, until the recent availability of direct results from numerical relativity computations, which could include the complete merger and ring-down phase of the orbital evolution. Unfortunately these calculations are not yet of sufficient precision to strenuously test PN methods intrinsically. By contrast, the gravitational self-force approach has become capable of advancing to extremely high precision, and of thereby testing most of the various techniques used in PN calculations. Although restricted to the extreme-massratio limit, self-force calculations are now able to verify both the methods and results of PN work, and even of extending it. In fact, as will be demonstrated, they now have high enough precision to be able to determine new coefficients analytically.
