Multivariate analysis was conducted to explore the moist temperate forests of the Shangla district, Khyber Pakhtunkhwa. The prime objective was to quantitatively describe and differentiate the vegetation groups and the factors that determine the boundaries and composition of plant communities in the Shangla district. This was achieved by sampling all common species in a complex vegetation mosaic coinciding with local gradients in topography and soil distribution. Ward’s clustering dendrogram demonstrated four significant vegetation clusters with respect to environmental effects. These four major groups of the tree vegetation were superimposed on the ordination plane: 1. Pinus wallichiana, the dominant group associated with Abies pindrow; 2. Abies pindrow and the Picea smithiana group; 3. Dominant Cedrus deodara associated with the Pinus wallichiana, Abies pindrow, Picea smithiana, and Quercus baloot group; 4. Pinus roxberghii pure group. The key controlling factors for each group were the environmental characteristics (i.e., edaphic factors, topographic factors, soil physical properties, and soil nutrients). The results revealed elevation (p <0.001) to be the prominent factor in the composition of plant communities. Furthermore, pH, soil moisture, maximum water holding capacity, and soil physical properties (sand, silt, and clay) also showed a significant (p < 0.05) relationship with vegetation. The other environmental factor did not show a significant relationship with vegetation. Ward’s cluster dendrogram of understory species also demonstrated four groups. Group 1 comprises two subgroups, a and b, with the highest number of species, i.e., Digeteria sanguinalis, Fragaria nubicola, Verbascum Thapsus, Pinus wallichiana seedlings, and Polygonatum multiflorium, respectively. The second large group contains twenty-five species out of eight stands, and the dominant species was Tagetis minuta. Eighteen species out of six stands were found in group 3, which was considered the smallest group. Group 4 consisted of seven stands containing twenty-four species of ground flora, with Anaphalis scopulosa followed by Adiantum venustum as the dominant species. The environmental characteristics of the understory vegetation showed a resemblance with the tree communities. With the exception of elevation, the other factors did not show a significant correlation.

Chinese olive (Canarium album), a characteristic fruit tree in tropical and subtropical areas, suffers greatly from low-temperature stress (LTS). The regulatory roles of microRNA (miRNA) in plant LTS responses have been confirmed in many plant species but not in C. album. In this study, a cold-tolerant cultivar ‘Rui’an 3′ (RA) and a susceptible cultivar ‘Qinglan 1’ (QL) treated at 25 °C (control, CK) and −3 °C (cold temperature treatment, CT) were subjected to small RNA (sRNA) and transcriptome sequencing for the exploration of the cold responses of C. album. Comparative sRNA sequencing analysis identified much fewer LTS-responsive, differentially expressed miRNAs (DEMs) in RA (4 DEMs) than in QL (23 DEMs). Cal-miR482-22 was found to be specifically induced by LTS in RA. Cal-miR397-3 was upregulated, while cal-miR398_2-3 and cal-undef-190 were downregulated after LTS only in QL. However, when compared with QL, a higher basic expression of cal-miR397-3, and lower expression of cal-miR398_2-3 and cal-undef-190 were found in RA, suggesting that they may contribute to the cold tolerance of RA. Comparative transcriptome analysis showed that the number of LTS-responsive differentially expressed genes (DEGs) identified in QL was larger than that in RA, and some DEGs were also predicted as the target genes of the identified DEMs, forming multiple differentially expressed miRNA–target gene pairs, such as cal-miR397-3_laccase 2, 4, 17, cal-miR482-22_suppressor of npr1-1, etc. Quantitative real time PCR results showed that the expression changes of DEGs and DEMs in different samples were generally consistent with the sequencing results. Our study indicated that the basic expression levels of some miRNAs (especially the cal-miR397-3, cal-miR398_2-3, and cal-miR482-22), and their target genes contribute greatly to the cold-tolerance characteristics of C. album. Our study is helpful for understanding the roles of miRNAs in the cold resistance and responses of C. album.

Published: July 2022

The noninvasive Balistocardiogram (BCG) signal is the recording of body movements due to heartbeat and blood flow through major arteries. This signal provides enough information to calculate the heart rate and its variations over time. The present paper proposes the design of a prototype of a low-cost electronic system to record the BCG signals acquired by means of a triaxial accelerometer and gyroscope. For the design of the system, an Arduino development board, the 9-axis MPU-9250 sensor (accelerometer, gyroscope and magnetometer), and the free software RealTerm are used. The system is connected by a USB port to a personal computer from where the entire system is governed.
A model of the system was built and tested successfully with arbitrary signals, checking the correct functioning of the system and recording the data in a text file for later analysis.

OBJETIVO: describir los efectos de la Diabetes Mellitus en pacientes diagnosticados con COVID-19. MÉTODO: se realizó una revisión basada en metaanálisis, artículos médicos y estudios previos. RESULTADOS: se estableció que la Diabetes Mellitus juega un papel importante y de carácter unidireccional en cuanto a los índices de mortalidad del COVID-19, ya que dicha patología conlleva aumento de severidad y mal pronóstico. El descontrol crónico de la Diabetes Mellitus se asocia a mayor susceptibilidad a infecciones, las cuales generalmente, producen un agravamiento de síntomas clínicos. CONCLUSIONES: el principal mecanismo fisiopatológico que el COVID-19 ocasiona en pacientes diabéticos, es la reducción de la expresión de Enzima Convertidora de Angiotensina 2 (ACE2), que induce daño celular, aumento de inflamación sistémica e insuficiencia respiratoria. Los elevados índices de mortalidad, severidad y mal pronóstico en pacientes diabéticos son más frecuentes en aquellos pacientes con mal apego terapéutico.

Model numerik hidrodinamika tiga dimensi merupakan salah satu pendekatan yang dapat dilakukan untuk menganalisis suatu fenomena perairan dengan mempertimbangkan pergerakan fluida secara horizontal dan vertikal. Pendekatan ini dilakukan untuk memperoleh nilai dan karakteristik fluida ditengah keterbatasan data lapangan untuk mengetahui profil vertikal perairan. Model dapat dibangun dengan dua pendekatan diskritisasi vertikal yaitu diskritisasi Sigma dan Hybrid. Kedua diskritisasi tersebut dijadikan perbandingan untuk mengetahui kecocokan formula terhadap kondisi perairan sebenarnya. Eksperimen dilakukan dengan menggunakan data bulan Januari 2019 melalui kedua tipe diskritisasi dengan menggunakan perlakukan yang sama sehingga diketahui perbedaan nilai yang dihasilkan dari kedua metode tersebut. Kedua tipe diskritisasi memiliki spesifikasi yang berbeda dengan kelebihan dan kekurangan pada masing-masing diskritisasi vertikal. Data hidrodinamika 3-dimensi yang dihasilkan menunjukan bahwa nilai kecepatan arus lebih besar dihasilkan dengan menggunakan diskritisasi Sigma jika dibandingkan dengan menggunakan Hybrid. Selain itu tren penggurangan kecepatan terhadap kedalaman juga teramati dengan baik sehingga diskritisasi Sigma bersifat lebih realistis dibandingkan Hybrid. Hasil verifikasi model dengan model lain pada aspek pasang surut menunjukan bahwa nilai RMSE dan Korelasi Pearson Diskritisasi Hybrid lebih rendah dibandingkan Sigma. Diskritisasi Sigma dengan nilai RMSE 0,05706 RMSE dan 0,965 Korelasi Pearson dan Diskritisasi Hybrid 0,0576 RMSE dan 0,966.
Probing Dynamics and Thermal Properties Inside Molecular Tori with CO Rovibrational Absorption Lines

Published: July 2022

Abstract
A recent hydrodynamic model, the radiation-driven fountain model (Wada et al. 2016), presented a dynamical picture that active galactic nuclei (AGNs) tori sustain their geometrical thickness by gas circulation around AGNs, and previous papers have confirmed that this picture is consistent with multiwavelength observations of nearby Seyfert galaxies. Recent near-infrared observations implied that CO rovibrational absorption lines (ΔJ = ± 1, v = 0 − 1, λ ∼ 4.7 μm) could probe the physical properties of the inside tori. However, the origin of the CO absorption lines has been under debate. In this paper, we investigate the origin of the absorption lines and conditions for detecting them by performing line radiative transfer calculations based on the radiation-driven fountain model. We find that CO rovibrational absorption lines are detected at inclination angles θ
obs = 50°–80°. At the inclination angle θ
obs = 77°, we observe multi-velocity components: inflow (v
LOS = 30 km s−1), systemic (v
LOS = 0 km s−1), and outflows (v
LOS = −75, − 95, and −105 km s−1). The inflow and outflow components (v
LOS = 30 and −95 km s−1) are collisionally excited at the excitation temperatures of 186 and 380 K up to J = 12 and 4, respectively. The inflow and outflow components originate from the accreting gas on the equatorial plane at 1.5 pc from the AGN center and the outflowing gas driven by AGN radiation pressure at 1.0 pc, respectively. These results suggest that CO rovibrational absorption lines can provide us with the velocities and kinetic temperatures of the inflow and outflow in the inner few parsec region of AGN tori, and the observations can probe the gas circulation inside the tori.
New Constraints on Cosmic Particle Populations at the Galactic Center Using X-Ray Observations of the Molecular Cloud Sagittarius B2
Authors: Rogers Field , Zhang Shuo , Perez Kerstin , Clavel Maïca , Taylor Afura 
Published: July 2022

Abstract
The Sagittarius B2 (Sgr B2) molecular cloud complex is an X-ray reflection nebula whose nonthermal X-ray emissions have continued to decrease since 2001 as it reprocesses one or more past energetic outbursts from the supermassive black hole Sagittarius A* at the Galactic Center. The X-ray reflection model explains the observed time variability of Sgr B2 and provides a window into the luminous evolutionary history of our nearest supermassive black hole. In light of evidence of elevated cosmic particle populations in the Galactic Center, X-rays from Sgr B2 are also of interest as a probe of low-energy (sub-GeV) cosmic rays, which may be responsible for an increasing relative fraction of the nonthermal emission as the contribution from X-ray reflection decreases. Here, we present the most recent NuSTAR and XMM-Newton observations of Sgr B2, from 2018, and we emphasize the Kα fluorescence line of neutral Fe. These 2018 observations reveal small-scale variations within lower-density portions of the complex, including brightening features, yet still enable upper limits on X-rays from low-energy cosmic-ray interactions in Sgr B2. We present Fe Kα line fluxes from cloud regions of different densities, facilitating comparison with models of ambient low-energy cosmic-ray interactions throughout the cloud.
Doppler-velocity Drifts Detected in a Solar Prominence
Authors: Zapiór Maciej , Heinzel Petr , Khomenko Elena 
Published: July 2022

Abstract
We analyzed multiline observations of a quiescent prominence from the slit spectrograph located at the Ondřejov Observatory. Dopplergrams and integrated intensity maps of the whole prominence were obtained from observations in six spectral lines: Ca ii H, Hϵ, Hβ, He i D3, Hα, and Ca ii IR. By combining integrated intensity maps with non-LTE radiative-transfer modeling, we carefully identified areas in an optically thin regime. The comparison of the Doppler-velocity maps and scatterplots from different lines shows the existence of differences in the velocity of ions and neutrals called velocity drift. The drift is of a local nature, present mostly at prominence edges in the area with a large velocity gradient, as can be tentatively expected based on multifluid MHD models. We could not explore the time evolution of the drift, since our data set consists of a single scan only. Our paper brings another contribution to a rather controversial problem of the detection of multifluid effects in solar prominences.
Measuring Star Formation and Black Hole Accretion Rates in Tandem Using Mid-infrared Spectra of Local Infrared Luminous Galaxies

Published: July 2022

Abstract
We present the results of a stacking analysis performed on Spitzer/Infrared Spectrograph high-resolution mid-infrared (mid-IR) spectra of luminous infrared galaxies (LIRGs) in the Great Observatories All-Sky LIRG Survey. By binning in relation to mid-IR active galactic nucleus (AGN) fraction and stacking spectra, we detect bright emission lines [Ne ii] and [Ne iii], which trace star formation, and fainter emission lines [Ne v] and [O iv], which trace AGN activity, throughout the sample. We find that the [Ne ii] luminosity is fairly constant across all AGN fraction bins, while the [O iv] and [Ne v] luminosities increase by over an order of magnitude. Our measured average line ratios, [Ne v]/[Ne ii] and [O iv]/[Ne ii], at low AGN fraction are similar to H II galaxies, while the line ratios at high AGN fraction are similar to LINERs and Seyferts. We decompose the [O iv] luminosity into star formation and AGN components by fitting the [O iv] luminosity as a function of the [Ne ii] luminosity and the mid-IR AGN fraction. The [O iv] luminosity in LIRGs is dominated by star formation for mid-IR AGN fractions ≲0.3. With the corrected [O iv] luminosity, we calculate black hole accretion rates (BHARs) ranging from 10−5
M
⊙ yr−1 at low AGN fractions to 0.2 M
⊙ yr−1 at the highest AGN fractions. We find that using the [O iv] luminosity, without correcting for star formation, can lead to overestimation of the BHAR by up to a factor of 30 in starburst-dominated LIRGs. Finally, we show that the BHAR/star formation rate ratio increases by more than three orders of magnitude as a function of mid-IR AGN fraction in LIRGs.
Effect of the Modified Gravity on the Large-scale Structure Formation
Authors: Kumar Sharma Ajay , Manohar Verma Murli 
Published: July 2022

Abstract
We investigate the formation of the large-scale structures in the present accelerated era in the f(R) gravity background. This is done by considering the linear growth of matter perturbations at low redshift z < 1. The effect of f(R) alters the behavior of the matter density perturbations from the matter-dominated universe to the late-time accelerated universe, which is encoded in the Newtonian gravitational constant as G → G
eff. The modified gravitational constant (G
eff) depends on the form of f(R). The late-time accelerated expansion affects the formation of large-scale structures by slowing down the growth of matter density. On the other hand, f(R) increases the growth rate of the matter density perturbations. We have found that the source term in the f(R) background, G
effΩ
m
, overcomes the accelerated expansion and the effect of accelerated expansion suppresses the formation of the large-scale structures in the asymptotic future.
An Extension of Gmunu: General-relativistic Resistive Magnetohydrodynamics Based on Staggered-meshed Constrained Transport with Elliptic Cleaning
Authors: Cheong 張 Patrick Chi-Kit 志杰 , Tung Pong David Yat , Long Yip Anson Ka , Feng Li Tjonnie Guang 
Published: July 2022

Abstract
We present the implementation of general-relativistic resistive magnetohydrodynamics solvers and three divergence-free handling approaches adopted in the General-relativistic multigrid numerical (Gmunu) code. In particular, implicit–explicit Runge–Kutta schemes are used to deal with the stiff terms in the evolution equations for small resistivity. The three divergence-free handling methods are (i) hyperbolic divergence cleaning (also known as the generalized Lagrange multiplier), (ii) staggered-meshed constrained transport schemes, and (iii) elliptic cleaning through a multigrid solver, which is applicable in both cell-centered and face-centered (stagger grid) magnetic fields. The implementation has been tested with a number of numerical benchmarks from special-relativistic to general-relativistic cases. We demonstrate that our code can robustly recover from the ideal magnetohydrodynamics limit to a highly resistive limit. We also illustrate the applications in modeling magnetized neutron stars, and compare how different divergence-free handling methods affect the evolution of the stars. Furthermore, we show that the preservation of the divergence-free condition of the magnetic field when using staggered-meshed constrained transport schemes can be significantly improved by applying elliptic cleaning.
