description: While the star formation rates and morphologies of galaxies have long been known to correlate with their local environment, the process by which these correlations are generated is not well understood. Galaxy groups are thought to play an important role in shaping the physical properties of galaxies before entering massive clusters at low redshift, and transformations of satellite galaxies likely dominate the buildup of local environmental correlations. To illuminate the physical processes that shape galaxy evolution in dense environments, we study a sample of 116 X-ray selected galaxy groups at z=0.2-1 with halo masses of 10^13-10^14 M_sun and centroids determined with weak lensing. We analyze morphologies based on HST imaging and colors determined from 31 photometric bands for a stellar mass-limited population of 923 satellite galaxies and a comparison sample of 16644 field galaxies. Controlling for variations in stellar mass across environments, we find significant trends in the colors and morphologies of satellite galaxies with group-centric distance and across cosmic time. Specifically at low stellar mass (log(M_stellar/M_sun) = 9.8-10.3), the fraction of disk-dominated star-forming galaxies declines from >50% among field galaxies to <20% among satellites near the centers of groups. This decline is accompanied by a rise in quenched galaxies with intermediate bulge+disk morphologies, and only a weak increase in red bulge-dominated systems. These results show that both color and morphology are influenced by a galaxy's location within a group halo. We suggest that strangulation and disk fading alone are insufficient to explain the observed morphological dependence on environment, and that galaxy mergers or close tidal encounters must play a role in building up the population of quenched galaxies with bulges seen in dense environments at low redshift.

Local witness for bipartite quantum discord

description: Recently, we proposed a method for the local detection of quantum correlations on the basis of local measurements and state tomography at different instances in time [Phys. Rev. Lett. 107, 180402 (2011)]. The method allows for the detection of quantum discord in bipartite systems when access is restricted to only one of the subsystems. Here, we elaborate the details of this method and provide applications to specific physical models. In particular, we discuss the performance of the scheme for generic complex systems by investigating thermal equilibrium states corresponding to randomly generated Hamiltonians. Moreover, we formulate an ergodicity-like hypothesis which links the time average to the analytically obtained average over the group of unitary operators equipped with the Haar measure.

description: This paper demonstrates a framework for a digital heritage research, Augmenting Kashgar, that facilitates the revitalizing of a historical architecture by using gamification, shape grammars and virtual reality. Examining current use of new media technologies, our methodology initially merges shape grammars, a generative modelling method, with gamification. It then extends the use of game elements into virtual reality in which the synthesizing of the old culture with a new one is the main accomplishment being sought. Firstly, gamification maps a community engagement plan while shape grammars serve for spatial analysis of the narrow alleys of Kashgar. Secondly, the gamified platform transitions from screen-based experience to immersive virtual reality interpretations.

description: We report a Plateau de Bure interferometer search for CII-158$μ$m emission from HCM6A, a lensed Lyman-$α$ emitter (LAE) at $z = 6.56$. Our non-detections of CII-158$μ$m line emission and 1.2mm radio continuum emission yield $3σ$ limits of L$_{\rm CII} < 6.4 \times 10^7 \times (ΔV/100 km s^{-1})^{1/2}$ L$_\odot$ on the CII-158$μ$m line luminosity and S$_{\rm 1.2mm} < 0.68$ mJy on the 1.2mm flux density. The local conversion factor between L$_{\rm CII}$ and star formation rate (SFR) yields an SFR $< 4.7$ M$_\odot$ yr$^{-1}$, $\approx 2$ times lower than that inferred from the ultraviolet (UV) continuum, suggesting that the local factor may not be applicable in high-$z$ LAEs. The non-detection of 1.2mm continuum emission yields a total SFR $< 28$ M$_\odot$/yr; any obscured star formation is thus within a factor of two of the visible star formation. Our best-fit model to the rest-frame UV/optical spectral energy distribution of HCM6A yields a stellar mass of $1.3 \times 10^9$ M$_\odot$ and an SFR of ~10 M$_\odot$/yr, with negligible dust obscuration. We fortuitously detect CO J=3-2 emission from a $z=0.375$ galaxy in the foreground cluster Abell370, obtaining a CO line luminosity of L$^\prime ({\rm CO}) > (8.95 \pm 0.79) \times 10^8$ K km s$^{-1}$ pc$^2$, and a molecular gas mass of M$({\rm H_2}) > (4.12 \pm 0.36) \times 10^9$ M$_\odot$, for a CO-to-H$_2$ conversion factor of 4.6 M$_\odot$ (K km s$^{-1}$ pc$^2$)$^{-1}$.

Weapon of the Discontented? Trans-River Migration as Tax Avoidance Practice and Lever in Eastern Bukhara

description: Until the early twentieth century, the border formed between contemporary Tajikistan and Afghanistan by the River Panj/Amu Darya was relatively easily traversable, even for larger groups of people with bulk loads and animals. Migration from one bank to the other was frequent and family units in riparian areas often had members on both sides of the river. Migration, especially collective outmigration, was, however, also an act of protest by dissatisfied peasants and pastoralists who sought to evade disproportionate or irregular taxes. Out-migration affected the interests of authorities and different social actors more intensely than other forms of evasive protest; it forced rulers or local authorities to negotiate terms of return, or contend with labour deficits, degradation of lands and irrigation structures, (cash) crop shortages, and unprotected border zones. Evasive tax flight and barter arrangements for return were a promising avenue for poorer population segments to pressure authorities for better conditions. This implied the involvement of mediators, community elders, local authorities, and others, who negotiated on behalf of the different stakeholders.

This paper examines various incidences of evasive, trans-border migration in the late 19th and early 20th centuries against the background of British and Russian colonial encroachment and increasing marginalisation of these riparian regions and population regimes in the border lands. It argues that marginality equipped the local population with a lever for pressuring authorities, which, however, could also be turned against them.

description: This article examines the history of Soviet-Afghan encounters in northern Afghanistan during the Soviet occupation. Drawing on archival materials from the former Soviet Union as well as recently published memoir collections by Soviet border guards, it shows how during the 1980s, northern Afghanistan was subjected to a unique regime of degraded sovereignty. While all regions of Afghanistan were subject to military occupation by the Soviet Army, in northern Afghanistan, 62,000 Soviet Border Troops occupied the northern reaches. Their goal was not only to secure  the Soviet-Afghan border, but also to eliminate mujāhidīn forces in Badakhshan, encourage peaceful and commercial cross- border interactions between Soviet and Afghan Badakhshan, and secure the entire territory inside an “antiseptic” green zone extending 100 to 120 kilometers into northern Afghanistan. As they did so, many elements of the Soviet border regime migrated into Afghanistan itself. Building on earlier work on the making of the Soviet border through areas of security inside the USSR, this piece shows the afterlives of that border as something also capable of being extended outside the USSR itself. In doing so, it not only enhances our understanding of the Soviet-Afghan War but also reveals the Soviet Union and its border forces to be transnational actors in their own right, rather than mere defenders of a statist territorial order.

description: Cygnus A harbours the nearest powerful radio jet of an Fanaroff-Riley (FR) class II radio galaxy in a galaxy cluster where the interaction of the jet with the intracluster medium (ICM) can be studied in detail. We use a large set of Chandra archival data, VLA and new LOFAR observations to shed new light on the interaction of the jets with the ICM. We identify an X-ray cavity in the distribution of the X-ray emitting plasma in the region south of the Cyg A nucleus which has lower pressure than the surrounding medium. The LOFAR and VLA radio observations show that the cavity is filled with synchrotron emitting plasma. The spectral age and the buoyancy time of the cavity indicates an age at least as large as the current Cyg A jets and not much larger than twice this time. We suggest that this cavity was created in a previous active phase of Cyg A when the energy output of the Active Galactic Nucleus (AGN) was about two orders of magnitude less than today.

description: We obtain exact analytic expressions for a class of functions expressed as integrals over the Haar measure of the unitary group in d dimensions. Based on these general mathematical results, we investigate generic dynamical properties of complex open quantum systems, employing arguments from ensemble theory. We further generalize these results to arbitrary eigenvalue distributions, allowing a detailed comparison of typical regular and chaotic systems with the help of concepts from random matrix theory. To illustrate the physical relevance and the general applicability of our results we present a series of examples related to the fields of open quantum systems and nonequilibrium quantum thermodynamics. These include the effect of initial correlations, the average quantum dynamical maps, the generic dynamics of system-environment pure state entanglement and, finally, the equilibration of generic open and closed quantum systems.

description: Currently, the long-standing issue concerning the size of the gluonic content of the eta' and eta mesons remains unsettled. With this in mind we consider the central exclusive production (CEP) of eta', eta meson pairs in the perturbative regime, applying the Durham pQCD-based model of CEP and the `hard exclusive' formalism to evaluate the meson production subprocess. We calculate for the first time the relevant parton-level processes gg --> qqbar gg and gg --> gggg, where the final-state gg and qqbar pairs form a pseudoscalar flavour-singlet state. We observe that these amplitudes display some non-trivial and interesting theoretical properties, and we comment on how this can be understood in a MHV framework. Finally, we present a phenomenological study, and show that the cross sections for the CEP of eta', eta meson pairs are strongly sensitive to the size of the gluon content of these mesons. The observation of these processes could therefore provide important and novel insight into this problem.

description: Atypical PKCs are cell polarity kinases that operate at the plasma membrane where they function within multiple molecular complexes to contribute to the establishment and maintenance of polarity. In contrast to the classical and novel PKCs, atypical PKCs do not respond to diacylglycerol cues to bind the membrane compartment. Until recently it was not clear how aPKCs are recruited; whether aPKCs can directly interact with membranes or whether they are dependent on other protein interactors to do so. Two recent studies identified the pseudo-substrate region and the C1 domain as direct membrane interaction modules, however their relative importance and coupling are unknown. We combined molecular modelling and functional assays to show that the regulatory module of aPKCι, comprising the PB1 pseudo-substrate and C1 domains, forms a cooperative and spatially continuous invariant membrane interaction platform. Furthermore, we show the coordinated orientation of membrane-binding elements within the regulatory module requires a key PB1-C1 interfacial β-strand (BSL). We show this element contains a highly conserved Tyr residue that can be phosphorylated and that negatively regulates the integrity of the regulatory module, leading to membrane release. We thus expose a hitherto unknown regulatory mechanism of aPKCι membrane binding and release during cell polarization.

description: Hong Kong’s building density is one of the highest in the world. Since ventilation is a key element in sustainable and environmental design, there is a need to evaluate local wind environments of high dense cities such as Hong Kong. In recent years non-standard curvilinear residential buildings that don’t follow conventional rectilinear block structures are becoming increasingly more popular. Though various studies of ventilation conditions of conventionally design buildings have been made, research of non-standard curvilinear building layouts is still limited. Previous research mainly explored rectilinear block-shaped layouts that typically cause a so called ‘Wall-Effect’ by blocking adequate ventilation on street- and mid-levels around buildings. Our paper presents and summarizes the analysis of airflow and ventilation of non-standard curvilinear buildings based on Computational Fluid Dynamics (CFD) simulations. The Flow Simulation of Solidworks has been used as our analysis software tools. Its technology is based upon the use of Cartesian based meshes and solving the Navier-Stokes equations. Nonstandard and curvilinear shaped building arrangements are categorized into various groups and analyzed in respect to their performance of ventilation on street and mid-levels using a case study of high rise buildings in Sha Tin, Hong Kong. Hong Kong’s climate is subtropical warm and humid in summer, subsequently a higher ventilation is needed and building design has to accommodate good airflow around the buildings. Our findings show that curvilinear buildings lead to a more favourable ventilation environment since they have a smaller wind resistance. Non-standard curvilinear designs perform better in terms of general ventilation since the airflow around the buildings is faster and less turbulent. Our simulations present that convex-shaped buildings have a better overall wind environment than concave-shaped ones. We conclude our paper with a classification of various nonstandard curvilinear buildings that offer a general better airflow and ventilation due to their shape. This classification allows designer to understand quickly wind resistance, airflow, and turbulences that a non-standard curvilinear design has on the immediate environment.

description: In recent decades, cold atom experiments have become increasingly complex. While computers control most parameters, optimization is mostly done manually. This is a time-consuming task for a high-dimensional parameter space with unknown correlations. Here we automate this process using a genetic algorithm based on Differential Evolution. We demonstrate that this algorithm optimizes 21 correlated parameters and that it is robust against local maxima and experimental noise. The algorithm is flexible and easy to implement. Thus, the presented scheme can be applied to a wide range of experimental optimization tasks.

Thermal to Nonthermal Energy Partition at the Early Rise Phase of Solar Flares

description: In some flares the thermal component appears much earlier than the nonthermal component in X-ray range. Using sensitive microwave observations we revisit this finding made by Battaglia et al. (2009) based on RHESSI data analysis. We have found that nonthermal microwave emission produced by accelerated electrons with energy of at least several hundred keV, appears as early as the thermal soft X-ray emission indicative that the electron acceleration takes place at the very early flare phase. The non-detection of the hard X-rays at that early stage of the flares is, thus, an artifact of a limited RHESSI sensitivity. In all considered events, the microwave emission intensity increases at the early flare phase. We found that either thermal or nonthermal gyrosynchrotron emission can dominate the low-frequency part of the microwave spectrum below the spectral peak occurring at 3-10 GHz. In contrast, the high-frequency optically thin part of the spectrum is always formed by the nonthermal, accelerated electron component, whose power-law energy spectrum can extend up to a few MeV at this early flare stage. This means that even though the total number of accelerated electrons is small at this stage, their nonthermal spectrum is fully developed. This implies that an acceleration process of available seed particles is fully operational. While, creation of this seed population (the process commonly called `injection' of the particles from the thermal pool into acceleration) has a rather low efficiency at this stage, although, the plasma heating efficiency is high. This imbalance between the heating and acceleration (in favor of the heating) is difficult to reconcile within most of available flare energization models. Being reminiscent of the tradeoff between the Joule heating and runaway electron acceleration, it puts additional constraints on the electron injection into the acceleration process.

description: Percolation theory is usually applied to lattices with a uniform probability p that a site is occupied or that a bond is closed. The more general case, where p is a function of the position x, has received less attention. Previous studies with long-range spatial variations in p(x) have only investigated cases where p has a finite, non-zero gradient at the critical point p_c. Here we extend the theory to two-dimensional cases in which the gradient can change from zero to infinity. We present scaling laws for the width and length of the hull (i.e. the boundary of the spanning cluster). We show that the scaling exponents for the width and the length depend on the shape of p(x), but they always have a constant ratio 4/3 so that the hull's fractal dimension D=7/4 is invariant. On this basis, we derive and verify numerically an asymptotic expression for the probability h(x) that a site at a given distance x from p_c is on the hull.

The successful axionic co-genesis requires a supersymmetry breaking scale of O(10^{6-7}) GeV, which is consistent with the recently discovered standard-model like Higgs boson of mass about 126 GeV. Although the saxion generically decays into a pair of axions, their abundance sensitively depends on the saxion stabilization mechanism as well as couplings with the Higgs field. We discuss various ways to make the saxion dominantly decay into the right-handed neutrinos rather than into axions, and show that the abundance of axion dark radiation can be naturally as small as ΔN_{\rm eff} \lesssim {\cal O}(0.1), which is allowed by the Planck data.

description: We study the vacuum stability and unitarity conditions for a 125 GeV Standard Model (SM)-like Higgs boson mass in the type-II seesaw model. We find that, as long as the seesaw scale is introduced below the SM vacuum instability bound, there exists a large parameter space predicting a 125 GeV Higgs mass, irrespective of the exact value of the seesaw scale, satisfying both stability and unitarity conditions up to the Planck scale. We also study the model predictions for the Higgs partial decay widths in the diphoton and Z+photon channels with respect to their SM expectations and find that the decay rates for these two processes are correlated. We further show that for any given enhancement in the Higgs-to-diphoton rate over its SM expectation, there exists an upper bound on the type-II seesaw scale, and hence, on the masses of the associated doubly- and singly-charged Higgs bosons in the allowed parameter space. For instance, if more than 10% enhancement persists in the Higgs-to-diphoton channel, the upper limit on the type-II seesaw scale is about 450 GeV which is completely within the reach of the 14 TeV LHC. We believe this to be an encouraging result for the experimental searches of the singly- and doubly-charged Higgs bosons which, in combination with improved sensitivity in the Higgs-to-diphoton and Higgs-to-Z+photon signal strengths, could probe the entire allowed parameter space of the minimal type-II seesaw model, and establish/eliminate it as a single viable extension of the SM.

description: Questo articolo analizza le evoluzioni del movimento nazionalista ed indipendentista còrso contemporaneo contestualizzando il suo sviluppo, descrivendone la recente svolta elettorale ed istituzionale inedita alla metà degli anni 2010 e discutendone gli elementi di interpretazione che contribuiscono ad apprezzare la portata di questa fase particolare della storia di un movimento fino ad ora relativamente poco studiato. This article analyses the evolution of the contemporary Corsican nationalist movement. It gathers background information about its birth and rise and it describes its recent and unprecedented electoral and institutional success in the 2010s. It then offers cautious elements of interpretation that aim at assessing the relevance of this particular phase in the history of a too often neglected theme.

CPT violation and triple-product correlations in B decays

description: The T-odd triple product (TP) asymmetries in B decays to a pair of vector mesons are treated as a good probe of CP violation because of the CPT symmetry. If CPT is no longer a good symmetry, such correlations between T-odd and CP-odd observables do not exist, and one might get unexpected nonzero TP asymmetries as a signal for CPT violation. We give a general formalism of TP asymmetries in the presence of CPT violation, either in decay or in neutral meson mixing. We also discuss how the observables depending on the transversity amplitudes are modified, and compare our expressions with the LHCb results, showing that the study of TP asymmetries might turn out to be one of the best probes for CPT violation.

Impact Ionization and Carrier Multiplication in Graphene

description: We develop a model for carrier generation by impact ionization in graphene, which shows that this effect is non-negligible because of the vanishing energy gap, even for carrier transport in moderate electric fields. Our theory is applied to graphene field effect transistors for which we parametrize the carrier generation rate obtained previously with the Boltzmann formalism [A. Girdhar and J. Leburton, Appl. Phys. Lett. 99, 229903 (2011)] to include it in a self-consistent scheme and compute the transistor I-V characteristics. Our model shows that the drain current exhibits an "up-kick" at high drain biases, which is consistent with recent experimental data. We also show that carrier generation affects the electric field distribution along the transistor channel, which in turn reduces the carrier velocity.
Physical Properties of the Low-Mass Eclipsing Binary NSVS 02502726

description: NSVS 02502726 has been known as a double-lined, detached eclipsing binary that consists of two low-mass stars. We obtained $BVRI$ photometric follow-up observations in 2009 and 2011 to measure improved physical properties of the binary star. Each set of light curves, including the 2008 data given by \cCakirli et al., was simultaneously analyzed with the previously published radial-velocity curves using the Wilson-Devinney binary code. The conspicuous seasonal light variations of the system are satisfactorily modelled by a two-spot model with one starspot on each component and by changes of the spot parameters with time. Based on 23 eclipse timings calculated from the synthetic model and one ephemeris epoch, an orbital period study of NSVS 02502726 reveals that the period has experienced a continuous decrease of $-5.9\times10^{-7}$ d yr$^{-1}$ or a sinusoidal variation with a period and semi-amplitude of 2.51 yrs and 0.0011 d, respectively. The timing variations could be interpreted as either the light-travel-time effect due to the presence of an unseen third body, or as the combination of this effect and angular momentum loss via magnetic stellar wind braking. Individual masses and radii of both components are determined to be $M_1$=0.689$\pm$0.016 M$_\odot$, $M_2$=0.341$\pm$0.009 M$_\odot$, $R_1$=0.707$\pm$0.007 R$_\odot$, and $R_2$=0.657$\pm$0.008 R$_\odot$. The results are very different from those of \cCakirli et al. with the primary's radius (0.674$\pm$0.006 R$_\odot$) smaller the secondary's (0.763$\pm$0.007 R$_\odot$). We compared the physical parameters presented in this paper with current low-mass stellar models and found that the measured values of the primary star are best fitted to a 79-Myr isochrone. The primary is in good agreement with the empirical mass-radius relation from low-mass binaries, but the secondary is oversized by about 85%.

description: La recente crisi ucraina, iniziata nel novembre del 2013, è stata considerata come una svolta cruciale per l‟intera regione post-sovietica, tracciando una linea divisoria tra due presunti vettori di evoluzione storica. In questo contributo, attraverso una ricostruzione della storia delle relazioni internazionali russo-ucraine in età post-sovietica, vengono posti alcuni quesiti di fondo alla luce dei recenti sviluppi: (a) che ruolo hanno giocato le alterne prospettive di integrazione regionale e i rispettivi processi di nation-building nella storia dei rapporti russo-ucraini in età post-sovietica?; (b) oggi possiamo identificare la nascita di due vettori divergenti di evoluzione storica post-sovietica?; (c) se sì, che significato assume questa separazione per l‟intero spazio postsovietico? The recent crisis in Ukraine, which began in November 2013, has been considered a crucial turning point for the whole post-Soviet area, allegedly tracing a dividing line between two vectors of historical evolution. In this contribution, through a reconstruction of the history of the international relations between Russia and Ukraine, and in the light of the most recent developments, some fundamental questions are posed: (a) what role was played by the different perspectives of regional integration and the respective processes of nation-building in the history of Russo-Ukrainian relations in the post-Soviet era? (b) Can we identify today the emergence of two diverging vectors of post-Soviet historical evolution? (c) If such is the case, what is the significance of this separation for the whole post-Soviet area?

description: Questo articolo propone una rassegna critica dei principali modi in cui le scienze sociali hanno operativizzato il concetto di cittadinanza al fine di aprirlo alla ricerca empirica. Una prima serie di studi parte alla ricerca della cittadinanza concreta individuando al suo interno diverse componenti da osservare distintamente. Una seconda corrente la considera piuttosto come un prodotto culturale e osserva i diversi significati che ad essa vengono attribuiti. Riteniamo questo secondo approccio particolarmente proficuo per indagare la cittadinanza nazionale e la sua manifattura e sosteniamo l‟urgenza, in particolare per il caso italiano, di sviluppare un‟etnografia delle politiche pubbliche relative allo status citivitatis. This article proposes a critical survey of the main ways whereby social sciences have turned the notion of citizenship into an operational concept, in order to use it for empirical research. A first set of studies starts by searching for practical citizenship, identifying in the latter different elements to be observed separately. A second current, instead, considers citizenship as a cultural product, and examines the different meanings assigned to it. We consider this second approach to be more fruitful, if one intends to look into national citizenship and its manufacturing, and we argue that it is urgent, especially for the Italian case, to develop an ethnography of public policies related to the status citivitatis.
