We report the results of new XMM-Newton observations middle-aged ($\sim$10$^5$ yr) radio pulsar PSR J1740+1000 carried out in 2017-2018. These long pointings ($\sim$530 ks) show that non-thermal emission, well described by a power-law spectrum with photon index $\Gamma=1.80\pm0.17$, is pulsed $\sim$30% fraction above 2 keV. The thermal emission can be fit sum two blackbodies temperatures $kT_1=...

We confirm the planetary nature of two gas giants discovered by TESS to transit M dwarfs. TOI-3714 ($V=15.24,~J=11.74$) is an M2 dwarf hosting a hot Jupiter ($M_p=0.70 \pm 0.03~\mathrm{M_J}$ and $R_p=1.01 0.03~\mathrm{R_J}$) on orbital period $2.154849 0.000001$ days with resolved white companion. TOI-3629 ($V=14.63,~J=11.42$) M1 ($M_p=0.26 0.02~\mathrm{M_J}$ $R_p=0.74 0.02~\mathrm{R_J}$) $3.93...

This paper presents an updated scaling relation between the optical luminosity density (LD) of galaxies in $r$ band and warm-hot intergalactic medium (WHIM) cosmic filaments, using high-resolution EAGLE simulations. We find a strong degree correlation WHIM galaxy density, resulting two quantities that permits to predict filaments with scatter less than $\frac{1}{2}$ dex broad range smoothed fil...

Out of eight deaths caused worldwide, one death is due to air pollution exposure, making it the top global killers. Personal exposure measurement for real-time monitoring has been used inhaled dose estimation during various modes workplace commuting. However, dose-exposure studies long commutes are scarce and more information on doses needed. This study focuses personal exposures size-fractiona...

Background: Acyl hydrazones are an important class of heterocyclic compounds promising pharmacological characteristics. Malaria is a life-threatening mosquito-borne blood disease caused by a plasmodium parasite. In some places, malaria can be treated and controlled with early diagnosis. However, some countries lack the resources to do this effectively. Results: The present work involves the des...

We developed a parametric Galactic model toward the bulge by fitting to spatial distributions of Gaia DR2 disk velocity, VVV proper motion, BRAVA radial OGLE-III red clump star count, and OGLE-IV count microlens rate, optimized for use in microlensing studies. include asymmetric drift stars dependence velocity dispersion on location kinematic model, which has been ignored most previous models u...

Illicit drugs and their trafficking require worldwide efforts in investigation, detection, control. Colorimetric tests are often applied to identify drugs. Cocaine has some well-known adulterants that can provide a false positive response. Cucurbit[6]uril (CB[6]) been suggested as potential detector for cocaine other illicit This work uses silico methods evaluate the use of CB[6] detect these i...

Scintillation of compact radio sources results from the interference between images caused by multipath propagation, and probes intervening scattering plasma velocities emitting source screen. In FRB20201124A, a repeating fast burst (FRB) which entered period extreme activity, we obtained many detections in observations at upgraded Giant Metrewave Radio Telescope (uGMRT) Effelsberg 100\,m Teles...

Quantum mechanical (QM) calculations of noncovalent interactions are uniquely useful as tools to test and improve molecular mechanics force fields and to model the forces involved in biomolecular binding and folding. Because the more computationally tractable QM methods necessarily include approximations, which risk degrading accuracy, it is essential to evaluate such methods by comparison with...
