description: The Magellanic Clouds are nearby dwarf irregular galaxies whose morphologies show different properties when traced by different stellar populations, making them an important laboratory for studying galaxy morphologies. We study the morphology of the Magellanic Clouds using data from the VISTA survey of the Magellanic Clouds system (VMC). We used about $10$ and $2.5$ million sources across an area of $\sim105$ deg$^2$ and $\sim42$ deg$^2$ towards the Large and Small Magellanic Cloud (LMC and SMC), respectively. We estimated median ages of stellar populations occupying different regions of the near-infrared ($J-K_\mathrm{s}, K_\mathrm{s}$) colour-magnitude diagram. Morphological maps were produced and detailed features in the central regions were characterised for the first time with bins corresponding to a spatial resolution of $0.13$ kpc (LMC) and $0.16$ kpc (SMC). In the LMC, we find that main sequence stars show coherent structures that grow with age and trace the multiple spiral arms of the galaxy, star forming regions become dimmer as we progress in age, while supergiant stars are centrally concentrated. Intermediate-age stars, despite tracing a regular and symmetrical morphology, show central clumps and hints of spiral arms. In the SMC, young main sequence stars depict a broken bar. Intermediate-age populations show signatures of elongation towards the Magellanic Bridge that can be attributed to the LMC-SMC interaction $\sim200$ Myr ago. They also show irregular central features suggesting that the inner SMC has also been influenced by tidal interactions.

Manipulating single-photon transport in a waveguide-QED structure containing two giant atoms

description: We investigate coherent single-photon transport in a waveguide-QED structure containing two giant atoms. The unified analytical expressions of the single-photon scattering amplitudes applicable for different topological configurations are derived. The spectroscopic characteristics in different parameter regimes, especially the asymmetric Fano line shapes and the electromagnetically induced transparency (EIT)-like spectra, are analyzed in detail. Specifically, we find that the appearance of Fano line shapes is influenced by not only the phase delays between coupling points but also the topologies of system. We also summarize the general conditions for appearance of EIT-like spectra by analyzing the master equation and verify these conditions by checking the corresponding analytical expressions of the scattering spectra. These phenomena may provide powerful tools for controlling and manipulating photon transport in future quantum networks.

description: One new triterpenoid saponin (1), as well as six known ones (2–7), were isolated from the ethanol extract of the thorns of Gleditsia sinensis. Their structures were elucidated by extensive spectroscopic analysis in conjunction with chemical evidence. Cytotoxic activity of compounds 1–6 was evaluated against human breast cancer MCF 7 cells in vitro by the MTT method. Our results revealed moderate activities for compounds 1–6 with IC50 values of 18.43, 30.47, 18.46, 10.02, 30.76, and 17.32 μM, respectively. Furthermore, compounds 1, 3, 4, and 6 induced apoptosis in MCF 7 cell, with 1 and 6 causing late apoptosis of MCF 7 cells, while 3 and 4 acting oppositely.

description: CT image-based diagnosis of the stomach is developed as a new way of diagnostic method. A virtual unfolded (VU) view is suitable for displaying its wall. In this paper, we propose a semi-automated method for generating VU views of the stomach. Our method requires minimum manual operations. The determination of the unfolding forces and the termination of the unfolding process are automated. The unfolded shape of the stomach is estimated based on its radius. The unfolding forces are determined so that the stomach wall is deformed to the expected shape. The iterative deformation process is terminated if the difference of the shapes between the deformed shape and expected shape is small. Our experiments using 67 CT volumes showed that our proposed method can generate good VU views for 76.1% cases.

description: The mergers of supermassive black hole binaries (SMBHBs) promise to be incredible sources of gravitational waves (GWs). While the oscillatory part of the merger gravitational waveform will be outside the frequency sensitivity range of pulsar timing arrays (PTAs), the non-oscillatory GW memory effect is detectable. Further, any burst of gravitational waves will produce GW memory, making memory a useful probe of unmodeled exotic sources and new physics. We searched the North American Nanohertz Observatory for Gravitational Waves (NANOGrav) 11-year data set for GW memory. This dataset is sensitive to very low frequency GWs of $\sim3$ to $400$ nHz (periods of $\sim11$ yr $-$ $1$ mon). Finding no evidence for GWs, we placed limits on the strain amplitude of GW memory events during the observation period. We then used the strain upper limits to place limits on the rate of GW memory causing events. At a strain of $2.5\times10^{-14}$, corresponding to the median upper limit as a function of source sky position, we set a limit on the rate of GW memory events at $<0.4$ yr$^{-1}$. That strain corresponds to a SMBHB merger with reduced mass of $ηM \sim 2\times10^{10}M_\odot$ and inclination of $ι=π/3$ at a distance of 1 Gpc. As a test of our analysis, we analyzed the NANOGrav 9-year data set as well. This analysis found an anomolous signal, which does not appear in the 11-year data set. This signal is not a GW, and its origin remains unknown.

description: A sizable rate of events, with several pairs of $b$-quarks produced contemporarily by multiple parton interactions, may be expected at very high energies as a consequence of the large parton luminosities. The production rates are further enhanced in hadron-nucleus reactions, which may represent a convenient tool to study the phenomenon. We compare the different contributions to $b{\bar b}b{\bar b}$ production, due to single and double parton scatterings, in collisions of protons with nuclei at the CERN-LHC.

description: The very first recruitment for a public relations practitioner in Malaysia was encountered in 1948 and was advertised by the federal government of the British Colony in Malaya. This paper examines the subsequent advertisements after Malaya sought independence from the British colonial government. A total of eleven recruitment advertisements were found before the formation of Malaysia on the 16th
September 1963. This paper outlines the advertisers, the titles of positions, as well as their qualifications and duties. The results show that the job requirement mainly came from the federal and local governments. Generally, the duties were related to information services and some specific responsibilities.

description: Tympanic membrane (TM) implants must fulfil a complex property profile in order to improve the quality of life of patients. These include acousto-mechanical vibration properties comparable to human TM, slow degradation rate, hydrophilicity and good biocompatibility. Human TM consists mainly of radial and circulating collagen fibers. Electro-spun membranes have a high potential for biomimetic replication of these structures. Furthermore, the nanofibers produced in this way morphologically resemble the natural extracellular molecules of TM: collagen and elastin. In addition, the acousto-mechanical properties of the membranes are determined by their complex, process-related microstructure. The aim of this work is development of a three-dimensional biomimetic TM implant based on polycaprolactone and silk fibroin by electrospinning. The influence of spinning solution viscosity, fiber diameter and orientation as well as porosity will be investigated. A numerical calculation of the effective stiffness of the materials is realized by the application of a homogenization process. Furthermore, a finite element model (FEM) is developed to simulate experimental tests of the sound transfer function with a laser Doppler vibrometer (LDV). Thus, the relationship between the microstructure of the nanofibers and the macroscale acousto-mechanical behavior of the implants can be identified by a parametric study. With the results obtained, real TM implants with a customized nanofiber structure produced, which are expected to have a sound transfer function comparable to human TM. Experiments on these TM implants will be performed and compared with the results of the FEM simulation in order to gain a broad understanding of the acousto-mechanical behavior.

description: We study phase transitions of the Potts model on the centered-triangular lattice with two types of couplings, namely $K$ between neighboring triangular sites, and $J$ between the centered and the triangular sites. Results are obtained by means of a finite-size analysis based on numerical transfer matrix calculations and Monte Carlo simulations. Our investigation covers the whole $(K, J)$ phase diagram, but we find that most of the interesting physics applies to the antiferromagnetic case $K<0$, where the model is geometrically frustrated. In particular, we find that there are, for all finite $J$, two transitions when K is varied. Their critical properties are explored. In the limits $J\to \pm \infty$ we find algebraic phases with infinite-order transitions to the ferromagnetic phase.

description: There is a growing concern about an impact of low-Earth-orbit (LEO) satellite constellations on ground-based astronomical observations, in particular, on wide-field surveys in the optical and infrared. The Zwicky Transient Facility (ZTF), thanks to the large field of view of its camera, provides an ideal setup to study the effects of LEO megaconstellations - such as SpaceX's Starlink - on astronomical surveys. Here, we analyze the archival ZTF observations collected between 2019 November and 2021 September and find 5301 satellite streaks that can be attributed to Starlink satellites. We find that the number of affected images is increasing with time as SpaceX deploys more and more satellites. Twilight observations are particularly affected - a fraction of streaked images taken during twilight has increased from less than 0.5% in late 2019 to 18% in 2021 August. We estimate that once the size of the Starlink constellation reaches 10,000, essentially all ZTF images taken during twilight may be affected. However, despite the increase in satellite streaks observed during the analyzed period, the current science operations of ZTF are not yet strongly affected. We also find that redesigning Starlink satellites (by installing visors intended to block sunlight from reaching the satellite antennas to prevent reflection) reduces their brightness by a factor of 4.6 +/- 0.1 with respect to the original design in g, r, and i bands.

description: Over the past few decades, different scholars have talked about the importance of awareness of one’s mental processes. They have proposed that by making students aware of their thinking, they would understand their capabilities, and would also monitor and evaluate their learning process more effectively. With respect to foreign language writing, in particular, portfolio is a helpful tool that can be used to promote the learners’ awareness because it is a collection of students’ texts which showcases the process of their writing development.In the present study, we show that how reflection on writing skills for EFL learners through portfolios may help them improve their metacognition or thinking about thinking process as well as their writing proficiency. There was also an attempt to show how such a reflection affects students’ attitude toward portfolios as an assessment tool.

description: Since the detection of high-energy cosmic neutrinos at the IceCube Neutrino Observatory in 2013, there has been an on-going search to find the origins of this flux. Despite recent evidence identifying a flaring blazar as a possible neutrino source, the vast majority of the diffuse neutrino flux measured by IceCube remains unexplained. Here, the latest IceCube results testing time-dependent correlation between neutrinos and Tidal Disruption Events (TDEs) are presented, limiting the contribution of jetted and non-jetted TDEs to the diffuse astrophysical neutrino flux to be less than 1.3% and 26% respectively at 90% confidence level. In addition, a dedicated search for neutrinos from the extraordinary transient AT2018cow are presented, and upper limits on the integrated neutrino emission are derived. Expected improvements from new and upcoming time domain optical surveys (such as ZTF and LSST) are also introduced.

description: Indirect land use change, an agricultural market leakage, has been a major controversy over the Environmental Protection Agency’s (EPA) requirement for corn-ethanol to reduce greenhouse gas (GHG) emissions by 20 percent relative to gasoline it is assumed to replace. This paper shows that corn-ethanol policies generate far greater carbon leakage in the fuel market itself. Hence, corn-ethanol does not meet EPA’s threshold, regardless of ethanol policy and whether one includes emissions from land use change.

We consider exponential iterated integrals in the particular case of fibered knot complements, where the fundamental group always has a faithful relative solvable completion.

description: Multicluster models consider that the nucleons can be moving around different centers in the nuclei. These models have been widely used to describe light nuclei but always considering that the mean field is composed of isotropic harmonic oscillators with different centers. In this work, we propose an extension of these models by using anisotropic harmonic oscillators. The strenghts of these oscillators, the distance among the different centers and the disposition of the nucleons inside every cluster are free parameters which have been fixed using the variational criterion. We have used a hamiltonian with the kinetic energy terms and a phenomenological two-body potential like Volkov V2 potential. All the one-body and two-body matrix elements have been analytically calculated. Only a numerical integration on the Euler angles, it is needed to carry out the projection on the values of the total spin of the state and its third component. We have studied the ground state and the first excited states of 8 Be, 12 C and 10 Be getting good results for the energies. The disposition of the nucleons in the different clusters have been also analyzed by using projection on the different cartesian planes getting much more information than when the radial one-body density is used.
Constraints on the energetics and plasma composition of relativistic jets in FR II sources

Publisher: name: arXiv
Year: 2003
Subjects: subject: Astrophysics (astro-ph)

description: We explore the energetics and plasma composition in FR II sources using a new simple method of combining shock dynamics and radiation spectrum. The hot spots are identified with the reverse shocked region of jets. With the one-dimensional shock jump conditions taking account of the finite pressure of hot ICM, we estimate the rest mass and energy densities of the sum of thermal and non-thermal particles in hot spots. Independently, based on the Synchrotron Self-Compton (SSC) model, we estimate the number and energy densities of {\it non-thermal} electrons using the multi-frequency radiation spectrum of hot spots. We impose the condition that the obtained rest mass, internal energy, and number densities of non-thermal electrons should be lower than those of the total particles determined by shock dynamics. We apply this method to Cygnus A. We examine three extreme cases of pure electron-positron pair plasma (Case I), pure electron-proton plasma with separate thermalization (Case II), and pure electron-proton plasma in thermal-equilibrium (Case III). By detailed SSC analysis for Cygnus A and 3C123, we find that the energy density of non-thermal electrons is about 10 times larger than that of magnetic field. We find that the Case III is not acceptable because predicted photon spectra do not give a good fit to the observed one. We find that Case II can also be ruled out since the number density of non-thermal electrons exceeds that of the total number density. Hence, we find that only pure $e^{\pm}$ plasma (Case I) is acceptable among the three cases. Total kinetic power of jet and electron acceleration efficiency are also constrained by internal energy densities of non-thermal and total particles.

We apply the propagation bound to prove the existence of infinite-volume dynamics as a strongly continuous group of automorphisms on the CAR algebra.

description: When a planet is only observed to transit once, direct measurement of its period is impossible. It is possible, however, to constrain the periods of single transiters, and this is desirable as they are likely to represent the cold and far extremes of the planet population observed by any particular survey. Improving the accuracy with which the period of single transiters can be constrained is therefore critical to enhance the long-period planet yield of surveys. Here, we combine Gaia parallaxes with stellar models and broad-band photometry to estimate the stellar densities of K2 planet host stars, then use that stellar density information to model individual planet transits and infer the posterior period distribution. We show that the densities we infer are reliable by comparing with densities derived through asteroseismology, and apply our method to 27 validation planets of known (directly measured) period, treating each transit as if it were the only one, as well as to 12 true single transiters. When we treat eccentricity as a free parameter, we achieve a fractional period uncertainty over the true single transits of $94^{+87}_{-58}\%$, and when we fix $e=0$, we achieve fractional period uncertainty $15^{+30}_{-6}\%$, a roughly threefold improvement over typical period uncertainties of previous studies.

description: Исследуется проблема утраты имманентного свойства субъектности в виртуальной реальности. Утверждается, что визуальная фиксация предметной повседневности превращается в способы ее индивидуализации, а сами изображения становятся способом конструирования мира. На примере анализа творческих работ студентов о будущем «умного города» описан один из вариантов конструирования будущего — процесс дизайнирования, раскрывающий многообразие вариантов предметной среды в образах будущего. В данном процессе система социальных коммуникаций с доминирующей образностью цифровых дискурсов относительно будущего подчиняет себе субъекта и задает определенные стандарты его описания и категоризации. Установлено, что конструируемый таким образом предметный мир имеет отчетливо выраженную интерсубъективную основу. Причиной тому является утрата чувства собственной субъектности, выражающаяся в «залипании» в виртуальной реальности. Возникает ситуация, когда субъект и объект в процессах дизайнирования будущего уже больше не находятся в отношениях взаимной детерминации, взаимного становления. Сделан вывод о том, что исходным условием предметного дизайна будущего становится удержание со-присутствия как отношений множественных Мы, где собственно отношения играют большую роль, чем смыслы.

description: We discuss the characteristic features of triple Cu-O2 layer cuprates superconductors, by comparing those of single and double layer cuprates superconductors. After a brief introduction to multilayer cuprates and their characteristic properties such as the doping imbalance between the inner and outer Cu-O2 planes (IP and OP, respectively) revealed by nuclear magnetic resonance, we present the experimental results of angle resolved photoemission and Raman scattering spectroscopy for the triple layer Bi2Sr2Ca2Cu3O10+z which showed two different superconducting gaps opening on the IP and OP. The doping dependence of the double peak structure in Raman spectra was found to be qualitatively consistent with that of single and double layer cuprates, if each layer doping for the IP and OP is taken into account. The fact that the IP and OP share the same electronic phase diagram and the same transition temperature (Tc) hints to a coupling between the IP and OP. Moreover, the energies of IP and OP Raman peaks were found to be very large, not scaling with Tc, which can be attributed to the strong influence of the pseudogap of the underdoped IP in triple layer cuprates. These findings suggest that the high Tc and the large gap ratio of triple layer cuprates are realized through a combination of the interlayer coupling between the OP and IP and the interaction between superconductivity and the pseudogap.

description: Grasslands received policy attention in the Czech Republic only just fifteen years ago, when they were threatened to be abandoned in the economic transition process. The supports to farming on grasslands have grown gradually, particularly after the EU accession. The policy followed the notion of jointness between grassland management and beef cattle raising and conditioned Agri-environmental (AE) and Less Favoured Areas (LFA) payments by a minimum livestock density. There are many reasons why the current policy will change in the new programme period. This paper attempts to assess the impact of the envisaged changes on grassland maintenance. It is showed that overall future supports to farming will be sufficient to keep positive profit on grassland farms, however the structure of supports might be less appropriate to the actual objectives of grassland protection and hence, there is a threat of policy failure in the end.

description: Anomalous moments of the top quark arises from one loop corrections to the vertices $\bar t t g$ and $\bar t t γ$. We study these anomalous couplings in different frameworks: effective theories, Standard Model and 2HDM. We use available experimental results in order to get bounds on these anomalous couplings.

Evolution of Neutral Oxygen During the Epoch of Reionization and its Use in Estimating the Neutral Hydrogen Fraction

description: We use synthetic sightlines drawn through snapshots of the Technicolor Dawn simulations to explore how the statistics of neutral oxygen OI absorbers respond to hydrogen reionization. The ionization state of the circumgalactic medium (CGM) initially roughly tracks that of the intergalactic medium, but beginning at $z=8$ the CGM grows systematically more neutral owing to self-shielding. Weak absorbers trace diffuse gas that lies farther from halos, hence they are ionized first, whereas stronger systems are less sensitive to reionization. The overall OI covering fraction decreases slowly with time owing to competition between ongoing enrichment and gradual encroachment of ionization fronts into increasingly overdense gas. While the declining covering fraction is partially offset by continued formation of new halos, the ionization of the diffuse gas causes the predicted line-of-sight incidence rate of OI absorbers to decline abruptly at the overlap epoch, in qualitative agreement with observations. In comparison to the recently-observed equivalent width (EW) distribution at $z\approx6$, the simulations underproduce systems with $EW \geq 0.1 \unicode{x212B}$, although they reproduce weaker systems with $EW \geq 0.05 \unicode{x212B}$. By $z\approx5$, the incidence of $EW < 0.1 \unicode{x212B}$ systems are overproduced, consistent with previous indications that the simulated ionizing background is too weak at $z<6$. The summed column densities of SiII and SiIV trace the total oxygen column, and hence the ratio of the OI and SiII + SiIV comoving mass densities traces the progress of reionization. This probe may prove particularly useful in the regime where $x_{HI} > 10\%$

description: The current paper investigates the medium term economic impact of climate changes on the EU agriculture. The yield change data under climate change scenarios are taken from the BIOMA (Biophysical Models Application) simulation environment. We employ CAPRI modelling framework to identify the EU aggregate economic effects as well as regional impacts. We take into account supply and market price adjustments of the EU agricultural sector as well as technical adaptation of crops to climate change. Overall results indicate an increase in yields and production level in the EU agricultural sector due to the climate change. In general, there are relatively small effects at the EU aggregate. For example, the value of land use and welfare change by approximately between -2% and 0.2%. However, there is a stronger impact at regional level with some stronger effects prevailing particularly in the Central and Northern EU and smaller impacts are observed in Southern Europe. Regional impacts of climate change vary by a factor higher up to 10 relative to the aggregate EU impacts. The price adjustments reduce the response of agricultural sector to climate change in particular with respect to production and income changes. The technical adaption of crops to climate change may result in a change production and land use by a factor between 1.4 and 6 relative to no-adaptation situation.

description: After the severe landslides that affected Rio de Janeiro in April 2010, causing 67 deaths, the city authorities implemented what they called “a paradigm shift” in responding to disasters. This new approach, which echoes international discourses on urban resilience, builds on the government of urban uncertainties through risk technologies. Such technologies have underpinned a biopolitics of favelas removals. From 2009 to 2016, approximately 21,000 families were expelled from their homes due to ‘disaster risk prevention’, now one of the core repertoires of urban policy in Rio. This research aims to understand how risk and resilience are mobilised to govern marginalised areas and groups, how this is grounded in a long history of state-led precarization of favelas and how favela dwellers have responded to and resisted attempts to remove their right to stay in place. The study builds on the results of a multi-sited case study in Rio by analysing five favelas over a total of 10 months between 2016 and 2017, involving archival research, politically engaged participant observation, semi-structured and in-depth interviews with key participants. The approach to data analysis draws on a hybrid thematic analysis driven by a feminist and postcolonial conceptual framework, moving between concepts of biopolitics, precarity, vulnerability and resistance. Analysed through the concepts of (urban) biopolitics and precarity, this new mode of risk-based urban governance appears as a depoliticised and de-historicised form of risk management in favelas, producing precarity and displacement rather than ‘resilience’. Along these lines, the thesis presents three key findings. First, the characterization of favelas as ‘high-risk areas’ through the governmental technologies of risk assessment serves to justify displacements, undermine favelados' agency and obscure the historical process of governmental precarization. Second, state-led precarization has been the key driver of favelas and favelados’ vulnerability, while simultaneously exposing both displaced and those left behind to further risks. Third, by articulating an interpretation of vulnerability as both a deliberate exposure to power and an essence of political resistance, this research shows how 4 favelados have successfully mobilized their shared and produced vulnerability to resist disaster risk displacements through epistemic, temporal, affective and material forms of contestation.

description: The Landau-Wilson field theory with $O(n)\times O(m)$ symmetry which describes the critical thermodynamics of frustrated spin systems with noncollinear and noncoplanar ordering is analyzed in $4 - \varepsilon$ dimensions within the minimal subtraction scheme in the six-loop approximation. The $\varepsilon$ expansions for marginal dimensionalities of the order parameter $n^H(m,4-\varepsilon)$, $n^-(m,4-\varepsilon)$, $n^+(m,4-\varepsilon)$ separating different regimes of critical behavior are extended up to $\varepsilon^5$ terms. Concrete series with coefficients in decimals are presented for $m=\{2, \dots, 6\}$. The \textit{diagram of stability} of nontrivial fixed points, including the chiral one, in $(m,n)$ plane is constructed by means of summing up of corresponding $\varepsilon$ expansions using various resummation techniques. Numerical estimates of the chiral critical exponents for several couples $\{m,n\}$ are also found. Comparative analysis of our results with their counterparts obtained earlier within the lower-order approximations and by means of alternative approaches is performed. It is confirmed, in particular, that in physically interesting cases $n=2, m=2$ and $n=2, m=3$ phase transitions into chiral phases should be first-order.

description: To write an articulate and coherent piece of writ-ing, people need to reflect upon different aspectsof their texts. For foreign language (FL) learners, inparticular, writing is a much more demanding skillto master and thus more attention should be paidto reflective practice in language classrooms. Todo so, researchers and teachers should first findout the extent to which FL students write reflec-tively. The next step, which has received scantattention so far, should be a thorough investiga-tion into the inhibitors to reflective writing fromboth students’ and teachers’ viewpoints. Havingthis in mind, the researchers made an attempt todelve into the aforementioned issue and foundthat, among other factors, low language profi-ciency and insufficient teacher training are themost prominent factors in this regard.
