Adipose and Plasma microRNAs miR-221 and 222 Associate with Obesity, Insulin Resistance, and New Onset Diabetes after Peritoneal Dialysis

Background: The correlation between microRNA, obesity, and glycemic intolerance in patients on peritoneal dialysis (PD) is unknown. We aimed to measure the adipose and plasma miR-221 and -222 levels, and to evaluate their association with adiposity, glucose intolerance, and new onset diabetes mellitus (NODM) after the commencement of PD. Methods: We prospectively recruited incident adult PD patients. miR-221 and -222 were measured from adipose tissue and plasma obtained during PD catheter insertion. These patients were followed for 24 months, and the outcomes were changes in adiposity, insulin resistance, and NODM after PD. Results: One hundred and sixty-five patients were recruited. Patients with pre-existing DM had higher adipose miR-221 (1.1 ± 1.2 vs. 0.7 ± 0.9-fold, p = 0.02) and -222 (1.9 ± 2.0 vs. 1.2 ± 1.3-fold, p = 0.01). High adipose miR-221 and -222 levels were associated with a greater increase in waist circumference (miR-221: beta 1.82, 95% CI 0.57–3.07, p = 0.005; miR-222: beta 1.35, 95% CI 0.08–2.63, p = 0.038), Homeostatic Model Assessment for Insulin Resistance (HOMA) index (miR-221: beta 8.16, 95% CI 2.80–13.53, p = 0.003; miR-222: beta 6.59, 95% CI 1.13–12.05, p = 0.018), and insulin requirements (miR-221: beta 0.05, 95% CI 0.006–0.09, p = 0.02; miR-222: beta 0.06, 95% CI 0.02–0.11, p = 0.002) after PD. The plasma miR-222 level predicted the onset of NODM (OR 8.25, 95% CI 1.35–50.5, p = 0.02). Conclusion: miR-221 and -222 are associated with the progression of obesity, insulin resistance, and NODM after PD.
No slip gravity

A subclass of the Horndeski modified gravity theory we call No Slip Gravity has particularly interesting properties: 1) a speed of gravitational wave propagation equal to the speed of light, 2) equality between the effective gravitational coupling strengths to matter and light, Gmatter and Glight, hence no slip between the metric potentials, yet difference from Newton's constant, and 3) suppressed growth to give better agreement with galaxy clustering observations. We explore the characteristics and implications of this theory, and project observational constraints. We also give a simple expression for the ratio of the gravitational wave standard siren distance to the photon standard candle distance, in this theory and others, and enable a direct comparison of modified gravity in structure growth and in gravitational waves, an important crosscheck.
Attitude and behavior of senior high school students toward environmental conservation

Abstract. Berame JS, Lumaban NW, Delima SB, Mercado RL, Bulay ML, Morano AB, Parohinog CDMG. 2022. The attitude and behavior of senior high school students toward environmental conservation. Biodiversitas 23: 5267-5277. The worsening environmental problems have become a serious concern prompting humanity to search for solutions aiming for environmental management through understanding the relationship between human-environmental attitude and behavior with the belief that humans are the prime contributor to both - problem and the solution. By acknowledging this existing situation, this study was designed to assess the senior high school student’s level of understanding of and attitude toward the environment and the effects of both variables on their ecological behavior. A sequential strategy under mixed-method research was used in the study. A survey questionnaire containing both qualitative and quantitative questions was distributed to and answered by the respondents, followed by a focus group discussion that solidified and substantiated the quantitative result. Analysis of the responses demonstrated that students’ environmental attitudes were uncertain and connoted that they have intermediate attitudes and were all observed to be connected to their intermediate ecological behavior. Further, it revealed anthropocentric attitudes were dominant among students. This environmental attitude, together with human dominance over nature, denoted correlation along ecological behavior toward conservation policies, environmental threats and support for population growth policies, while eco-centric attitudes do not correlate to ecological behavior. In conclusion, the limited and ambiguous knowledge of senior high school students on the rule of human and nature need reinforcement for them to develop a good quality viewpoint about nature and willingly advocate environmental protection through their actions.
Different time course recovery of muscle edema within the quadriceps femoris and functional performance after single- vs multi-joint exercises

This study aimed to verify the time course recovery of muscle edema within the quadriceps femoris and functional performance after lower-body single- and multi-joint exercises. For this within-participant unilateral and contralateral experimental design, fourteen untrained young males performed a unilateral knee extension exercise (KE), and a unilateral leg press (LP) exercise in a counterbalanced order. At pre-, post-, 24 h, 48 h, 72 h, and 96 h after exercise, the peak torque (PT), unilateral countermovement jump (uCMJ) performance, and rectus femoris (RF) and vastus lateralis (VL) muscle thicknesses were recorded in both legs. The PT decreased immediately after (p = 0.01) both exercises (KE and LP) and was fully recovered 24 h after KE (p = 0.38) and 48 h after LP (p = 0.68). Jump height and power, in the uCMJ, followed the same PT recovery pattern after both exercises. However, vertical stiffness (Kvert) was not affected at any time point after both protocols. The RF thickness increased after both exercises (p = 0.01) and was fully restored 48 h after KE (p = 0.86) and 96 h after LP (p = 1.00). The VL thickness increased after both exercises (p = 0.01) and was fully restored 24 h after LP (p = 1.00) and 48 h after KE (p = 1.00). The LP exercise, compared to KE, induced more prolonged impairment of functional performance and delayed recovery of RF muscle edema. However, the VL edema-induced muscle swelling recovery was delayed after the KE exercise. The different recovery kinetics between functional performance and muscle damage should be taken into consideration depending on the objectives of the next training sessions.
A Search for Lyα Emitters at Redshift 3.7

We present the results of a survey for emission-line objects, based on optical intermediate-band (λc = 5736 Å and Δλ = 280 Å) and broadband (B, V, R, and i′) observations of the Subaru/XMM-Newton Deep Field with the 8.2 m Subaru telescope and the Subaru Prime Focus Camera (Suprime-Cam). All the data were obtained during the guaranteed time observations of the Suprime-Cam instrument. The intermediate-band image covered a sky area of 10. ′62 × 12. ′40 ≈ 132 arcmin2 in the Subaru/XMM-Newton Deep Field (Ouchi et al.). Using this image, we found 23 emission-line sources whose observed emission-line equivalent widths are greater than 250 Å. Their optical multicolor properties indicate that six emission-line sources are Lyα emitters at z ≈ 3.7 (Δz ≈ 0.22). They are either intense starburst galaxies or active galactic nuclei–like quasars at z ≈ 3.7. Two more emission-line sources may also be Lyα emitters at z ≈ 3.7, although their multicolor properties are marginal. Among the remaining 15 emission-line objects, eight objects appear to be strong emission-line galaxies at lower redshift; e.g., [O II] λ3727 emitters at z ≈ 0.54, Hβ at z ≈ 0.18, or [O III] λ5007 emitters at z ≈ 0.15. The remaining seven objects are unclassified because they are too faint to be detected in broadband images. We discuss the observational properties of these strong emission-line sources. In particular, our data allow us to estimate the star formation density at z ≈ 3.7 for the first time.
Magnetism near half-filling of a Van Hove singularity in twisted graphene bilayer

Twisted graphene bilayers (TGBs) have low-energy van Hove singularities (VHSs) that are strongly localized around AA-stacked regions of the moire pattern1-6. Therefore, they exhibit novel many-body electronic states, such as Mott-like insulator7 and unconventional superconductivity8. Unfortunately, these strongly correlated states were only observed in magic angle TGBs with the twist angle 1.1°, requiring a precisely tuned structure. Is it possible to realize exotic quantum phases in the TGBs not limited at the magic angle? Here we studied magnetic properties of a TGB with θ ~ 1.64° and demonstrated that localized magnetic moments emerge in the AA-stacked regions when a VHS of the TGB is close to the Fermi level. The VHS splits into two spin-polarized states flanking the Fermi energy. Since the low-energy VHSs are quite easy to be reached in slightly TGBs, our result therefore provides a facile direction to realize novel quantum phases in graphene system.
Effects of trail and greenspace exposure on hospitalisations in a highly populated urban area: retrospective cohort study of the Houston Bayou Greenways program

ABSTRACT Exposure to urban greenspaces has been linked to improved health outcomes for prevalent conditions. Studies have observed traditional block greenspaces, whereas linear trail systems could maximise health impacts by reaching greater population percentages. We assessed the temporal effects of linear greenspace exposure on health by examining the impact of the Bayou Greenways (BGs) linear trail implementation on health conditions and hospitalisations. We retrospectively analysed inpatient hospitalisation records for Harris County, Texas, from 2015–2019. Thirteen health conditions were explored with hospital admission rates per zip code as the primary outcome. Primary exposure variables were attributes of the BGs interconnected trail system: access duration, ten-minute walk proximity, and access point density. Models were evaluated to assess associations between admission rates in zip codes with and without BGs. Unadjusted analyses for zip codes with high access to trails had reduced odds of admission for obesity (OR, 95%CI: 0.18, 0.10–0.30), ischaemic heart disease (IHD; OR, 95%CI: 0.56, 0.34–0.93), and acute myocardial infarction (AMI; OR, 95%CI: 0.59, 0.37–0.94). Zip codes with >30% of the population within a ten-minute walk showed significant reduction in odds of hospital admission for obesity, (OR, 95%CI: 0.07, 0.03-0.17), IHD (OR, 95%CI: 0.23, 0.12–0.44), and AMI (OR, 95%CI: 0.29, 0.14–0.62). Analysis of socio-economic status (SES) demonstrated that low income and less densely populated areas showed increased admissions for obesity, IHD, AMI, and all-cause hospitalisations. Access to trails may be important in lower SES areas. These findings can inform public policy to integrate greenspace to support healthier communities.
Eigenfunctions for Partially Rectangular Billiards

In this note, we further develop the methods of Burq and Zworski (2005) to study eigenfunctions for billiards which have rectangular components: these include the Bunimovich billiard, the Sinai billiard, and the recently popular pseudointegrable billiards (Bogomolny et al., 1999). The results are an application of a “black-box” point of view as presented in Burq and Zworski (2004).
Optimum Design of Wind Tunnel Contractions

A method for the design of low-speed wind tunnel contractions is presented. An optimum contraction is considered to be the shortest one that satisfies flow quality requirements in the test section; i.e., avoids any boundary-layer separation and supplies flow to the test section with a specified degree of uniformity. It is shown that by optimizing duct wall curvature distribution, it is possible to reduce contraction length to about one-half of that presently used in practice for a given test section flow quality. For example, a contraction with an area ratio of eight for a large wind tunnel can be as short as one inlet radius. The present method closely relates the shape and length of the contraction to the degree of flow quality required in the test section, to the contraction ratio, to the inlet flow Reynolds number, and to the viscous flow conditions in the settling chamber upstream of the contraction inlet. Presented are data to guide the design of a contraction of any combination of these parameters. The results of the study indicate that the avoidance of turbulent boundary-layer separation near the exit need not be a design driver; rather, the possibility of boundary-laye r relaminarizati on near the exit needs attention.
Effect of mentorship on regular teachers' selfefficacy towards implementation of inclusive education at basic education level

Impaired teachers' self-efficacy has contributed to delays in the implementation of inclusive education in Nigeria. Unfortunately, several efforts established towards ensuring the actualization of the Salamanca Declaration in Nigeria are yet to produce desired results. Although some past studies identified a mentor-mentee approach as a model that promotes the efficient implementation of established policies, paucity of research evidence exists on the implication of mentor-mentee approaches on the construction of teachers' self-efficacy for inclusive education, particularly at the basic level of education. Objectives. This study was conducted to investigate the effect of mentorship on in-service regular teachers' self-efficacy towards the implementation of inclusive education at the basic education level in Gombe State, Nigeria. Methods. A quasi-experimental research design was adopted for the study, while a purposive sampling technique was used to select 42 participants aged between 20 and 45 (M = 33.90, SD = 6.35) from two local government areas of the Gombe South Senatorial District. Participants were assigned to treatment and control groups, with 21 participants in each group. The Teachers' Sense of Efficacy Scale (a = .81) was used for data collection. Data collected was analysed with an independent sample t-test. Results. Findings showed the efficacy of a mentoring training program on the self-efficacy of in-service regular teachers towards effective implementation of inclusive education at the basic level of education. Also, male and older teachers had higher self-efficacy for the implementation of Inclusive education at the basic education level. Conclusion. Mentorship programs significantly facilitate the achievement of inclusive education, particularly at the basic level of education. Welldesigned mentorship programs for early career in-service regular teachers would equip them with an orientation that would guide them towards effective implementation of inclusive education at the basic level of education. Based on the outcome of the study appropriate mentorship strategy for novice teachers was recommended.
Origin of misalignments: protostellar jet, outflow, circumstellar disc, and magnetic field

Recent observations uncover various phenomena around the protostar such as misalignment between the outflow and magnetic field, precession of the jet, and time variability of the ejected clumps, whose origins are under debate. We perform a three-dimensional resistive magnetohydrodynamics simulation of the protostar formation in a star-forming core whose rotation axis is tilted at an angle $45^\circ$ with respect to the initial magnetic field, in which the protostar is resolved with a spatial resolution of $0.01\,$au. In low-dense outer region, the prestellar core contracts along the magnetic field lines due to the flux freezing. In high-dense inner region, on the other hand, the magnetic dissipation becomes efficient and weakens the magnetic effects when the gas number density exceeds about $10^{11}\,{\rm cm^{-3}}$. Then, the normal direction of the flattened disc is aligned with the angular momentum vector. The outflow, jet, and protostellar ejection are driven from different scales of the circumstellar disc and spout in different directions normal to the warped disc. These axes do not coincide with the global magnetic field direction and vary with time. This study demonstrates that a couple of misalignment natures reported by observations can be simultaneously reproduced only by assuming the star-forming core rotating around a different direction from the magnetic field.
Scalable explicit implementation of anisotropic diffusion with Runge-Kutta-Legendre super-time stepping

An important ingredient in numerical modelling of high temperature magnetised astrophysical plasmas is the anisotropic transport of heat along magnetic field lines from higher to lower temperatures.Magnetohydrodynamics (MHD) typically involves solving the hyperbolic set of conservation equations along with the induction equation. Incorporating anisotropic thermal conduction requires to also treat parabolic terms arising from the diffusion operator. An explicit treatment of parabolic terms will considerably reduce the simulation time step due to its dependence on the square of the grid resolution ($\Delta x$) for stability. Although an implicit scheme relaxes the constraint on stability, it is difficult to distribute efficiently on a parallel architecture. Treating parabolic terms with accelerated super-time stepping (STS) methods has been discussed in literature but these methods suffer from poor accuracy (first order in time) and also have difficult-to-choose tuneable stability parameters. In this work we highlight a second order (in time) Runge Kutta Legendre (RKL) scheme (first described by Meyer et. al. 2012) that is robust, fast and accurate in treating parabolic terms alongside the hyperbolic conversation laws. We demonstrate its superiority over the first order super time stepping schemes with standard tests and astrophysical applications. We also show that explicit conduction is particularly robust in handling saturated thermal conduction. Parallel scaling of explicit conduction using RKL scheme is demonstrated up to more than $10^4$ processors.
Species determination and heavy metal content of sailfin catfish (Pterygoplichthys pardalis) from Tempe Lake, South Sulawesi, Indonesia

Abstract. Kasmiati, Latuconsina N, Putri AA, Khasanah R, Nurfaidah, Fahrul, Syahrul, Metusalach. 2022. Species determination and heavy metal content of sailfin catfish (Pterygoplichthys pardalis) from Tempe Lake, South Sulawesi, Indonesia. Biodiversitas 23: 4409-4417. Sailfin catfish is invasive alien species that has become dominant in Indonesian freshwater, including in Tempe Lake, South Sulawesi, Indonesia. Despite their abundance, these sailfin catfish are not utilized because of suspicions that they are contaminated by heavy metals that can endanger human health. The purposes of this study were to determine the sailfin catfish species present in Tempe Lake and measure the content of heavy metals Hg, Pb, and Cd in various body parts. Fish species were identified based on abdominal patterns, while heavy metal content was meaured by atomic absorption. The heaviest two body parts were the head (34.04%) and flesh (26.64%), heavy metal content detected in the liver (0.0402-0.0928 mg/kg), gut (0.0322-0.0671 mg/kg), gills (0.319-0.0865 mg/kg), dark meat (0.0268-0.0589 mg/kg), white meat (0.0221-0.0470 mg/kg), bones (0.0180-0.0519 mg/kg), and skin/scales (0.0257-0.0675 mg/kg). All of them were below the FAO/WHO 1989, US-EPA 1999, and the Indonesian National Standards. The government health and safety guidelines for fish to be safe for human consumption were Hg <0.005 mg/kg, Pb<0.10 mg/kg and Cd<0.02 mg/kg. Therefore the abundant sailfin catfish Pterygoplichthys pardalis in Tempe Lake could be consumed directly and as ingredients in other food products.
Azimuthal anisotropy in Cu+Au collisions at 
sNN=200
 GeV

The azimuthal anisotropic flow of identified and unidentified charged particles has been systematically studied in Cu+Au collisions at sNN=200 GeV for harmonics n=1–4 in the pseudorapidity range |η|<1. The directed flow in Cu+Au collisions is compared with the rapidity-odd and, for the first time, the rapidity-even components of charged particle directed flow in Au+Au collisions at sNN=200 GeV. The slope of the directed flow pseudorapidity dependence in Cu+Au collisions is found to be similar to that in Au+Au collisions, with the intercept shifted toward positive pseudorapidity values, i.e., the Cu-going direction. The mean transverse momentum projected onto the spectator plane 〈px〉 in Cu+Au collision also exhibits approximately linear dependence on pseudorapidity with the intercept at about η≈−0.4 (shifted from zero in the Au-going direction), closer to the rapidity of the Cu+Au system center of mass. The observed dependencies find a natural explanation in a picture of the directed flow originating partly due the “tilted source” and partly due to the asymmetry in the initial density distribution. A charge dependence of 〈px〉 was also observed in Cu+Au collisions, consistent with an effect of the initial electric field created by charge difference of the spectator protons in two colliding nuclei. The rapidity-even component of directed flow in Au+Au collisions is close to that in Pb+Pb collisions at sNN=2.76 TeV, indicating a similar magnitude of dipolelike fluctuations in the initial-state density distribution. Higher harmonic flow in Cu+Au collisions exhibits similar trends to those observed in Au+Au and Pb+Pb collisions and is qualitatively reproduced by a viscous hydrodynamic model and a multiphase transport model. For all harmonics with n≥2 we observe an approximate scaling of vn with the number of constituent quarks; this scaling works as well in Cu+Au collisions as it does in Au+Au collisions.
Einstein constraints on asymptotically Euclidean manifolds

We consider the Einstein constraints on asymptotically euclidean manifolds $M$ of dimension $n \geq 3$ with sources of both scaled and unscaled types. We extend to asymptotically euclidean manifolds the constructive method of proof of existence. We also treat discontinuous scaled sources. In the last section we obtain new results in the case of non-constant mean curvature.
A Data Mining/ANFIS and Adaptive Control for Detection and Mitigation of Attacks on DC MGs

The integration of information and communication technologies (ICTs) has provided modern smart grids, such as direct current (DC) microgrids (MGs), with various advantages, e.g., the possibility of large-scale integration of renewable energy sources and complex control schemes. This extensive deployment of ICTs, however, makes DC MGs prone to a variety of cyber threats, e.g., false data injection (FDI) attacks. On this basis, this paper develops online detection and mitigation schemes to counter FDI attacks against DC MGs. Initially, in the offline training of the detection scheme, the density-based spatial clustering of applications with noise (DBSCAN) method is used for extracting prescriptive features of DC MG measurements and clustering them in healthy and under-attack operations under several uncertainties in DC MG operations. These features are used to train an adaptive network-based fuzzy inference system (ANFIS) architecture for the online identification of FDI attacks. Afterward, the trained ANFIS is used to detect FDI attacks and obtain the attack vectors benefiting from the real-time measurements estimated by an optimal state observer. Finally, an adaptive model predictive controller (AMPC) is developed to update the power-sharing commands—and mitigate the FDI attack—using the ANFIS’s obtained attack vectors. The effectiveness of the proposed framework is evaluated for several realistic FDI attack scenarios and different uncertainties. To show the scalability of the proposed detection and mitigation methods, a DC MG with eight converters is also studied in the presence of FDI attacks and uncertainties using real-time simulations.
