description: Aims. To search for these rare objects, we study 32 Galactic O-type stars that were reported as SB1s in the literature. In our sample we include Cyg X-1, which is known to host an accreting stellar-mass BH, and HD 74194, a supergiant fast X-ray transient, in order to validate our methodology. The final goal is to characterise the nature of the unseen companions to determine if they are MS stars, stripped helium stars, triples, or compact objects such as neutron stars or stellar-mass BHs. Methods. After measuring radial velocities and deriving orbital solutions for all the systems in our sample, we performed spectral disentangling to extract putative signatures of faint secondary companions from the composite spectra. We derived stellar parameters for the visible stars and estimated the mass ranges of the secondary stars using the binary mass function. Variability observed in the photometric TESS light curves was also searched for indications of the presence of putative companions, degenerate or not. Results. In 17 of the 32 systems reported as SB1s, we extract secondary signatures, down to mass ratios of ~0.15. For the 17 newly detected double-lined spectroscopic binaries (SB2s), we derive physical properties of the individual components and discuss why they have not been detected as such before. Among the remaining systems, we identify nine systems with possible NS or low-mass MS companions. For Cyg X-1 and HD 130298, we are not able to extract any signatures for the companions, and the minimum masses of their companions are estimated to be about 7Msun. Our simulations show that secondaries with such a mass should be detectable from our dataset, no matter their nature: MS stars, stripped helium stars or even triples. While this is expected for Cyg X-1, confirming our methodology, our simulations also strongly suggest that HD 130298 could be another candidate to host a stellar-mass BH.

description: Abstract: The reasons for migration, are most of the people come to the city in search of job. However, they have to satisfy themselves with low-grade works in the city like domestic servants, hawkers, pity traders etc. Other prominent reasons for migration include marriage, business, etc. In Pune the condition is no different. Being close to Mumbai and an educational and industrial hub, these migrants come to Pune for jobs and education. Those who are rich can afford to live in the core city as “Citizens” while the poor and unemployed people become the “Slum-dwellers”. High rate of immigration create a problem of housing, safe drinking water, schools, colleges, public toilet facility, inadequate sewage, disposal provisions, ,mushrooming of slum on roads, traveling facilities, entertainment, park and garden and basic amenities in Pune city.

description: Harmful algal blooms (HABs) can result in a substantial increase in the organic and solids load in the seawater feed to be treated at a desalination plant. In this chapter, the removal of this material is addressed in the context of the multi-barrier treatment process for seawater reverse osmosis (SWRO) as presented in Chapter 8 on risk management for HAB events. While this chapter covers removal of non-toxic material, Chapter 10 builds upon these principles and discusses the mechanisms and effectiveness for each barrier with respect to toxin removal. This chapter covers only the main barriers used in the SWRO desalination plants for HAB bloom risk mitigation, though the authors acknowledge that other niche treatment barriers exist in SWRO systems. The treatment processes discussed here are chlorination and dechlorination, dissolved air flotation (DAF), granular media filtration (GMF), microscreens for microfiltration/ultrafiltration (MF/UF), MF/UF itself, cartridge filtration and SWRO. Coagulation is discussed in general terms and then more specifically for DAF, GMF, and MF/UF pretreatments. Each treatment process is broken down into a discussion of how the process works and then how HAB cells affect the process operation. Importantly, the chapter deals with how upstream actions can detrimentally affect downstream treatment processes with respect to algal blooms. In particular, this chapter discusses removal mechanisms for algal organic matter (AOM) and how operational actions can prevent detrimental effects of AOM. As discussed in Chapter 2, the chemical composition of AOM usually includes proteins, polysaccharides, nucleic acids, lipids, and other dissolved organic substances. AOM compounds typically cover a wide size spectrum, ranging from less than 1 nm to more than 1 mm. Based on their size cut-off, GMF and MF/UF are expected to remove only part of high molecular weight AOM (as shown in Chapter 2, Figure 2.2). SWRO is expected to achieve complete removal of AOM, but will suffer from fouling issues if AOM is not removed upstream

description: Seven new [acronyculatins I-O (1-7)] and four known acetophenone monomers were isolated from a CH 3 OH/CH 2 Cl 2 (1:1) extract (N089419) of Acronychia trifoliolata provided by the U.S. National Cancer Institute (NCI, Frederick, MD, USA). Their structures were characterized by using various NMR and HRMS techniques. Among the known compounds, the structure of acronyculatin B (8) was revised. Some of the isolated compounds were evaluated for antiproliferative activity against human cancer cell lines. While most of the tested compounds were not cytotoxic, acronyculatins I (1) and J (2) showed moderate antiproliferative activity.

description: We present the design and performance of the TANSPEC, a medium-resolution $0.55-2.5~μ$m cryogenic spectrometer and imager, now in operation at the 3.6-m Devasthal Optical Telescope (DOT), Nainital, India. The TANSPEC provides three modes of operation which include, photometry with broad- and narrow-band filters, spectroscopy with short slits of 20$^{\prime \prime}$ length and different widths (from 0.5$^{\prime \prime}$ to 4.0$^{\prime \prime}$) in cross-dispersed mode at a resolving power R of $\sim$2750, and spectroscopy with long slits of 60$^{\prime \prime}$ length and different widths (from 0.5$^{\prime \prime}$ to 4.0$^{\prime \prime}$) in prism mode at a resolving power R of $\sim$100-350. TANSPEC's imager mode provides a field of view of 60$^{\prime \prime} \times 60^{\prime \prime}$ with a plate scale of 0.245$^{\prime \prime}$/pixel on the 3.6-m DOT. The TANSPEC was successfully commissioned during April-May 2019 and the subsequent characterization and astronomical observations are presented here. The TANSPEC has been made available to the worldwide astronomical community for science observations from October 2020.

description: A discrete and exact algorithm for obtaining planetary systems is derived in a recent article (Eur. Phys. J. Plus 2022, 137:99). Here the algorithm is used to obtain planetary systems with forces different from the Newtonian inverse square gravitational forces. A Newtonian planetary system exhibits regular elliptical orbits, and here it is demonstrated that a planetary system with pure inverse forces also is stable and with regular orbits, whereas a planetary system with inverse cubic forces is unstable and without regular orbits. The regular orbits in a planetary system with inverse forces deviate, however, from the usual elliptical orbits by having revolving orbits with tendency to orbits with three or eight loops. Newton's Proposition 45 in $\textit{Principia}$ for the Moon's revolving orbits caused by an additional attraction to the gravitational attraction is confirmed, but whereas the additional inverse forces stabilize the planetary system, the additional inverse cubic forces can destabilize the planetary system at a sufficient strength.

The structures of the new compounds were elucidated by spectroscopic analysis, and their absolute configurations were determined by electronic circular dichroism calculations. Seven of the isolates were examined for anti-HIV effects, and compounds 1a and 1b showed moderate anti-HIV activity with EC50 values of 6.3 and 5.3 μM.

description: The permanent electric dipole moment (EDM) of the $^{171}$Yb $(I=1/2)$ atom is measured with atoms held in an optical dipole trap (ODT). By enabling a cycling transition that is simultaneously spin-selective and spin-preserving, a quantum non-demolition measurement with a spin-detection efficiency of 50$\%$ is realized. A systematic effect due to parity mixing induced by a static E field is observed, and is suppressed by averaging between measurements with ODTs in opposite directions. The coherent spin precession time is found to be much longer than 300 s. The EDM is determined to be $d({\rm^{171}Yb})={\color{black}(-6.8\pm5.1_{\rm stat}\pm1.2_{\rm syst})\times10^{-27}\ e\ \rm cm}$, leading to an upper limit of $|d({\rm^{171}Yb})|<{\color{black}1.5\times10^{-26}\ e\ \rm cm}$ ($95\%$ C.L.). These measurement techniques can be adapted to search for the EDM of $^{225}$Ra.

description: Several redback and black widow millisecond pulsar binaries have episodes of flaring in X-rays and optical. We initially detected such behavior from the Fermi selected redback candidate 1FGL J0523.5$-$2529 during optical time-series monitoring. Triggered observations with the Neil Gehrels Swift Observatory over the next $\approx100$ days showed episodic flaring in X-rays with luminosity up to $8\times10^{33}$ erg s$^{-1}$ ($\sim100$ times the minimum), and a comparable luminosity in the optical/UV, with similar power-law spectra of $f_ν\proptoν^{-0.7}$. These are the most luminous flares seen in any non-accreting "spider" pulsar system, which may be related to the large size of the companion through the fraction of the pulsar wind that it or its ablated wind intercepts. Simultaneously with an optical flare, we see Balmer-line and He I emission, not previously known in this object, which is evidence of a stellar wind that may also inhibit detection of radio pulsations. The quiescent optical light curves, while dominated by ellipsoidal modulation, show evidence of variable non-uniform temperature that could be due either to large starspots or asymmetric heating of the companion by the pulsar. This may explain a previous measurement of unusual non-zero orbital eccentricity as, alternatively, distortion of the radial-velocity curve by the surface temperature distribution of the large companion.

description: In the standard picture, episodes of luminous quasar activity are directly related to supermassive black hole (SMBH) growth. The ionising radiation emitted over a quasar's lifetime alters the ionisation state of the surrounding intergalactic medium (IGM), enhancing the Ly$α$ forest transmission -- so-called proximity effect -- which can be observed in absorption spectra of background sources. Owing to the finite speed of light, the transverse direction of the proximity effect is sensitive to the quasar's radiative history, resulting in `light echoes' that encode the growth history of the SMBH on Myr-timescales. In this paper, we introduce a new technique to photometrically map this quasar light echoes using Ly$α$ forest tomography by using a carefully selected pair of narrow-band filters. A foreground narrow-band filter is used to measure Ly$α$ forest transmission along background galaxies selected as Ly$α$ emitters by a background narrow-band filter. This novel double narrow-band tomographic technique utilises the higher throughput and wider field of view of imaging over spectroscopy to efficiently reconstruct a two-dimensional map of Ly$α$ forest transmission around a quasar. We present a fully Bayesian framework to measure the luminous quasar lifetime of a SMBH from photometric IGM tomography, and examine the observational requirements. This new technique provides an efficient strategy to map a large area of the sky with a modest observing time and to identify interesting regions to be examined by further deep 3D follow-up spectroscopic Ly$α$ forest tomography.

description: We show that solutions of the 2D Fokker-Planck equation for bosons are defined globally in time and converge to equilibrium, and this convergence is shown to be exponential for radially symmetric solutions. The main observation is that a variant of the Hopf-Cole transformation relates the 2D equation in radial coordinates to the usual linear Fokker-Planck equation. Hence, radially symmetric solutions can be computed analytically, and our results for general (non radially symmetric) solutions follow from comparison and entropy arguments. In order to show convergence to equilibrium we also prove a version of the Csiszár-Kullback inequality for the Bose-Einstein-Fokker-Planck entropy functional.

description: Six acetophenone derivatives, acronyculatins I (1), J (2), K (3), L (4), N (5), and O (6), were recently isolated from Acronychia trifoliolata, and the structure of the known acronyculatin B (7) was revised. Because of the limited quantities of isolated products as well as their structure similarity, racemic acronyculatins I-L, N, O, and B (1-7) were synthesized to confirm their structures and to obtain sufficient material for biological evaluation. Trihydroxyacetophenone was converted to the target compounds by various sequences of hydroxy group protection, allylation or prenylation, and epoxidation followed by cyclization. C-Prenylations were carried out by direct addition of a prenyl group or through 1,3- or 3,3-sigmatropic rearrangement. The synthesized racemic compounds were evaluated in an anti-tumor-promoting assay using the Epstein-Barr virus early antigen (EBV-EA) activation induced by 12-O-tetradecanoylphorbol-13-acetate in Raji cells. All tested compounds significantly inhibited EBV-EA activation. Especially, racemic acronyculatin I (1) displayed the most potent inhibitory effects, with an IC 50 value of 7.3 μM.

description: We study spatially resolved scaling relations among stars, dust, and gas in ten nearby spiral galaxies. In a preceding paper Abdurro'uf et al. (2022), we have derived spatially resolved properties of the stellar population and dust by panchromatic spectral energy distribution (SED) fitting using piXedfit. Now, we investigate resolved star formation ($Σ_{\rm H_{2}}$--$Σ_{\rm SFR}$--$Σ_{*}$) and dust scaling relations. While the relations with all sub-galactic regions of the galaxies are reasonably tight ($σ\lesssim 0.3$ dex), we find that most of the scaling relations exhibit galaxy-to-galaxy variations in normalization and shape. Only two relations of $Σ_{\rm dust}$--$Σ_{\rm gas}$ and $Σ_{\rm dust}$--$Σ_{\rm H_{2}}$ do not show noticeable galaxy-to-galaxy variations among our sample galaxies. We further investigate correlations among the scaling relations. We find significant correlations among the normalization of the $Σ_{\rm H_{2}}$--$Σ_{\rm SFR}$--$Σ_{*}$ relations, which suggest that galaxies with higher levels of resolved $\text{H}_{2}$ fraction ($f_{\rm H_{2}}$) tend to have higher levels of resolved star formation efficiency (SFE) and specific star formation rate (sSFR). We also observe that galaxies with higher levels of resolved dust-to-stellar mass ratios tend to have higher levels of resolved sSFR, SFE, and $f_{\rm H_{2}}$. Moreover, we find that galaxies with higher global sSFR and less compact morphology tend to have higher levels of the resolved sSFR, SFE, and $f_{\rm H_{2}}$, which can explain the variations in the normalization of the $Σ_{\rm H_{2}}$--$Σ_{\rm SFR}$--$Σ_{*}$ relationships. Overall, we observe indications of the contributions of both global and local factors in governing the star formation process in galaxies.

description: Twelve benzylisoquinoline alkaloids, including pavine and phenanthroindolizidine types, were isolated from a MeOH/CH2Cl2 extract of Cryptocarya laevigata (stem bark) through bioactivity-guided fractionation for antitumor effects. Selected compounds were evaluated for antiproliferative activity against five human tumor cell lines, including a multidrug-resistant subline. Since more common 2,3,8,9-tetrasubstituted pavine alkaloids, such as crychine (3), exhibit very mild or no cytotoxicity, this compound type has not been well investigated for antitumor activity. Thus, this report is the first discovery of a 7-hydroxylated pavine alkaloid, (-)-neocaryachine (1), to demonstrate strong antiproliferative activity, with IC50 values of 0.06 to 0.41 μM against five tested tumor cell lines, including an MDR subline. Further mechanism of action studies revealed that 1 impacts the cellular S-phase by inducing DNA double-strand breaks.

description: We perform an expansion study of the Balmer dominated outer shock of the SNR 0519$-$69.0 in the LMC by using a combination of new HST WFC3 imagery obtained in 2020 and archival ACS images from 2010 and 2011. Thanks to the very long time baseline, our proper motion measurements are of unprecedented accuracy. We find a wide range of shock velocities, with the fastest shocks averaging 5280 km/s and the slowest grouping of shocks averaging just 1670 km/s. We compare the H_alpha images from HST with X-ray images from Chandra and mid-IR images from Spitzer, finding a clear anti-correlation between the brightness of the remnant in a particular location and the velocity of the blast wave at that location, supporting the idea that the bright knots of X-ray and IR emission result from an interaction with a dense inhomogeneous circumstellar medium. We find no evidence for X-ray emission, thermal or nonthermal, associated with the fastest shocks, as expected if the fastest velocities are the result of the blast wave encountering the lower density ambient medium of the LMC. We derive an age of the remnant of 670 +/- 70 yr, consistent with results derived from previous investigations.

description: Exoplanet science often involves using the system parameters of real exoplanets for tasks such as simulations, fitting routines, and target selection for proposals. Several exoplanet catalogues are already well established but often lack a version history and code friendly interfaces. Software that bridges the barrier between the catalogues and code enables users to improve the specific repeatability of results by facilitating the retrieval of exact system parameters used in an articles results along with unifying the equations and software used. As exoplanet science moves towards large data, gone are the days where researchers can recall the current population from memory. An interface able to query the population now becomes invaluable for target selection and population analysis. ExoData is a Python interface and exploratory analysis tool for the Open Exoplanet Catalogue. It allows the loading of exoplanet systems into Python as objects (Planet, Star, Binary etc) from which common orbital and system equations can be calculated and measured parameters retrieved. This allows researchers to use tested code of the common equations they require (with units) and provides a large science input catalogue of planets for easy plotting and use in research. Advanced querying of targets are possible using the database and Python programming language. ExoData is also able to parse spectral types and fill in missing parameters according to programmable specifications and equations. Examples of use cases are integration of equations into data reduction pipelines, selecting planets for observing proposals and as an input catalogue to large scale simulation and analysis of planets.

description: We show that quasicrystals exhibit anyonic behavior that can be used for topological quantum computing. In particular, we study a correspondence between the fusion Hilbert spaces of the simplest non-abelian anyon, the Fibonacci anyons, and the tiling spaces of a class of quasicrystals, which includes the one dimensional Fibonacci chain and the two dimensional Penrose tiling. A possible encoding on tiling spaces of topological quantum information processing is also discussed.

description: Abstract The term ‘human rights’ denotes all rights which are inherent in our nature & without which we cannot live as human beings. They are claims of the individual for such conditions as are essential for the fullest realization of the innate characteristic which nature has bestowed the people as a human being. The greatest protection of human rights emanates from a democratic framework grounded in the rule of law where the weakest should have the same opportunity as the strongest. They are essential for full development of human personality. But the violation of Human rights at all levels as common phenomenon everywhere in India. Violation of human Rights against women, children, lower castes, minority communities, workers etc. is increasing day by day. The North-East is an area of special significance from the viewpoint of Human Rights. In the name of the Draconian Act i.e Armed Forces Special Power Act, 1958, the armed forces can easily infringe upon individual liberty and even challenge the right to life of any person at any time. Racial discrimination among the Northeastern peoples living outside is also a big hurdle in the path of Hunan Rights.Nagaland is also not an exceptional because infringment of human rights can be seen in the fields of people’s rights, women’s rights, child rights and the rights of the persons with disabilities etc. The arduous task in front of us is to think about it and work seriously to prevent the violation of Human Rights of the people. Government is working very seriously in this regard. But above all the people from all the communities must be aware about their rights to check the violation of Human Rights. The objective of the paper is to analyse the concept of the Human Rights, to find out the issues, challenges and problems and to suggest possible measure for its improvement.

description: An extensively pursued current direction of research in physics aims at the development of practical technologies that exploit the effects of quantum mechanics. As part of this ongoing effort, devices for information processing, secure communication and high-precision sensing are being implemented with diverse systems, ranging from photons, atoms and spins to mesoscopic superconducting and nanomechanical structures. Their physical properties make some of these systems better suited than others for specific tasks; thus, photons are well suited for transmitting quantum information, weakly interacting spins can serve as long-lived quantum memories, and superconducting elements can rapidly process information encoded in their quantum states. A central goal of the envisaged quantum technologies is to develop devices that can simultaneously perform several of these tasks, namely, reliably store, process, and transmit quantum information. Hybrid quantum systems composed of different physical components with complementary functionalities may provide precisely such multi-tasking capabilities. This article reviews some of the driving theoretical ideas and first experimental realizations of hybrid quantum systems and the opportunities and the challenges they present and offers a glance at the near- and long-term perspectives of this fascinating and rapidly expanding field.

description: The Juggled interferometer (JIFO) is an earth-based gravitational wave detector using repeatedly free-falling test masses. With no worries of seismic noise and suspension thermal noise, the JIFO can have much better sensitivity at lower frequencies than the current earth-based gravitational wave detectors. The data readout method of a JIFO could be challenging if one adopts the fringe-locking method. We present a phase reconstruction method in this paper by building up a complex function which has a fringe-independent signal-to-noise ratio. Considering the displacement noise budget of the Einstein Telescope (ET), we show that the juggled test masses significantly improve the sensitivity at 0.1-2.5$\,$Hz even with discontinuous data. The science cases brought with the improved sensitivity would include detecting quasi-normal modes of black holes with $10^4-10^5\,M_{\odot}$, testing Brans-Dicke theory with black-hole and neutron-star inspirals, and detecting primordial-black-hole-related gravitational waves.

description: Hemispheric stroke survivors often show impairments in voluntary muscle activation. One potential source of these impairments could come from altered control of muscle, via disrupted motor unit (MU) firing patterns. In this study, we sought to determine whether MU firing patterns are modified on the affected side of stroke survivors, as compared with the analogous contralateral muscle.

description: The Wisconsin Plasma Astrophysics Laboratory (WiPAL) is a flexible user facility designed to study a range of astrophysically relevant plasma processes as well as novel geometries that mimic astrophysical systems. A multi-cusp magnetic bucket constructed from strong samarium cobalt permanent magnets now confines a 10 m$^3$, fully ionized, magnetic-field free plasma in a spherical geometry. Plasma parameters of $ T_{e}\approx5$ to $20$ eV and $n_{e}\approx10^{11}$ to $5\times10^{12}$ cm$^{-3}$ provide an ideal testbed for a range of astrophysical experiments including self-exciting dynamos, collisionless magnetic reconnection, jet stability, stellar winds, and more. This article describes the capabilities of WiPAL along with several experiments, in both operating and planning stages, that illustrate the range of possibilities for future users.

The Battlefield of the Trojan War. A New Philological and Geographical Analysis

description: At a significant point in the middle of his work, the Iliad poet previews the destruction of the wall of the ship enclosure on the Hellespont, a wall the Greeks had to erect to protect themselves after their most important troop leader Achilles had withdrawn from the war against Troy out of rancour. To erase all traces of this wall after the Trojan War ended, Apollo and Poseidon, according to this preview, unite eight rivers of the Troad in nine days of incessant rain from Zeus and, with this aid, wash the wall into the sea and cover the coast again with sand (Iliad M 10–35). This article proposes to identify and localise the hitherto only partially determined rivers of the eight-river catalogue (M 20–22) to understand the geography around Troy and thus ascertain Homer’s idea of the battlefield’s location. It becomes evident that this portrayal reflects a geometrical spatial pattern in concentric half-circles around the coastal areas on the Hellespont near Parium and Lampsacus, the later core settlement of the Greeks from northern Ionia. Such a geographical alignment accords with the general, finely interconnected consistency of the hidden as well as open local colour of the Iliad, which can best be seen in the rich images of nature and which reveals traces of Homer’s and his (contemporary) listeners’ knowledge of the geography inherent in the work and still verifiable today.
description: An zentraler Stelle in der Mitte des Werkes gibt der Dichter der Ilias eine Vorausschau auf die Zerstörung der Mauer um das Schiffslager am Hellespont, welche die Griechen zu ihrem Schutz errichten mussten, nachdem sich ihr wichtigster Truppenführer Achilleus aus Groll vom Kampf gegen Troia zurückgezogen hatte. Um nach Beendigung des Troianischen Krieges alle Spuren dieser Mauer zu beseitigen, vereinen laut dieser Vorausschau Apollon und Poseidon bei neuntägigem Dauerregen des Zeus acht Flüsse der Troas, spülen mit ihrer Hilfe die Mauer ins Meer und bedecken den Strand wieder mit Sand (Ilias M 10–35). Dieser Artikel hat das Ziel, die bislang erst teilweise bestimmten Flüsse des Acht-Flüsse-Katalogs (M 20–22) zu identifizieren und zu lokalisieren, um so Homers Erfassung des geographischen Raums um Troia und damit seine Vorstellung von der Lage des Schlachtfelds zu ermitteln. Es zeigt sich, dass seineDarstellung ein geometrisches Raummuster in konzentrischen Halbkreisen umdie Küstenstriche amHellespont bei Parion und Lampsakos, dem späteren Siedlungskern derGriechen aus Nord-Ionien, widerspiegelt. Zu einer solchen geographischen Zentrierung passt die durchgängige feinvernetzte Stimmigkeit des verborgenen und offenen Lokalkolorits in der Ilias, das sich amdeutlichsten in den zahlreichen Naturbildern fassen lässt und werkimmanente, noch heute verifizierbare Spuren der Landeskunde Homers und seiner (primären) Hörer verrät.

description: We present a theoretical model to describe the double-resonant scattering process in arbitrary carbon nanotubes. We use this approach to investigate the defect-induced $D$ mode in CNTs and unravel the dependence of the $D$-mode frequency on the CNT diameter and on the energy of the resonant optical transition. Our approach is based on the symmetry of the hexagonal lattice and geometric considerations, hence the method is independent of the exact model that is chosen to describe the electronic band structure or the phonon dispersion. We finally clarify the diameter dependence of this Raman mode that was controversely discussed in the past and demonstrate that, depending on the experimental conditions, in general two different dependencies can be measured. We also prove that carbon nanotubes with arbitrary chiral index can exhibit a $D$ mode in their Raman spectrum, in contrast to previous symmetry-based arguments. Furthermore, we give a direct quantification of the curvature-induced phonon frequency corrections of the $D$-mode in carbon nanotubes with respect to graphite.
