description: In this paper, we study capacity bounds for discrete memoryless broadcast channels with confidential messages. Two private messages as well as a common message are transmitted; the common message is to be decoded by both receivers, while each private message is only for its intended receiver. In addition, each private message is to be kept secret from the unintended receiver where secrecy is measured by equivocation. We propose both inner and outer bounds to the rate equivocation region for broadcast channels with confidential messages. The proposed inner bound generalizes Csiszár and Körner's rate equivocation region for broadcast channels with a single confidential message, Liu {\em et al}'s achievable rate region for broadcast channels with perfect secrecy, Marton's and Gel'fand and Pinsker's achievable rate region for general broadcast channels. Our proposed outer bounds, together with the inner bound, helps establish the rate equivocation region of several classes of discrete memoryless broadcast channels with confidential messages, including less noisy, deterministic, and semi-deterministic channels. Furthermore, specializing to the general broadcast channel by removing the confidentiality constraint, our proposed outer bounds reduce to new capacity outer bounds for the discrete memory broadcast channel.

description: Context: Hαimages of star bursting irregular galaxies reveal a large amount of extended ionized gas structures, in some cases at kpc-distance away from any place of current star forming activity. A kinematic analysis of especially the faint structures in the halo of dwarf galaxies allows insights into the properties and the origin of this gas component. This is important for the chemical evolution of galaxies, the enrichment of the intergalactic medium, and for the understanding of the formation of galaxies in the early universe. Aims: We want to investigate whether the ionized gas detected in two irregular dwarf galaxies (NGC 2366 and NGC 4861) stays gravitationally bound to the host galaxy or can escape from it by becoming a freely flowing wind. Methods: Very deep Hαimages of NGC 2366 and NGC 4861 were obtained to detect and catalog both small and large scale ionized gas structures down to very low surface brightnesses. Subsequently, high-resolution long-slit echelle spectroscopy of the Hαline was performed for a detailed kinematic analysis of the most prominent filaments and shells. To calculate the escape velocity of both galaxies and to compare it with the derived expansion velocities of the detected filaments and shells, we used dark matter halo models. Results: We detected a huge amount of both small scale (up to a few hundred pc) and large scale (about 1-2 kpc of diameter or length) ionized gas structures on our Hαimages. Many of the fainter ones are new detections. The echelle spectra reveal outflows and expanding bubbles/shells with velocities between 20 and 110 km/s. Several of these structures are in accordance with filaments in the Hαimages. A comparison with the escape velocities of the galaxies derived from the NFW dark matter halo model shows that all gas features stay gravitationally bound.

description: Project Panormos is an international archaeological research project, centred on a recently-identified ancient necropolis near Didyma, located on the Aegean coast of Turkey. Since its establishment in 2012, the research has been undertaken as a cooperative effort between archaeological researchers from DAI’s Istanbul department and the archaeological Museum of Balat / Miletus (Aydın province, Turkey). The project aims to examine a number of historical issues, ranging from the lifestyles and geographical origins of the individuals who were buried at the necropolis, to recording and interpreting details of local/regional funerary practices, and to improving our knowledge of trade and interaction during the early 1st millennium BC.

description: In this work, the P-P(P) Drell-Yan lepton pair production (DY) differential cross sections at hadrons colliders, such as LHC and TEVATRON, are studied in the ${k_{t}}$-factorization framework. In order to take into account the transverse momenta of incoming partons, we use the unintegrated parton distribution functions (UPDF) of Kimber et al (KMR) and Martin et al (MRW) in the leading order (LO) and next-to-leading-order (NLO) levels with the input MMHT2014 PDF libraries. Based on the different off-shell partonic matrix elements, we analyze the behaviors of DY differential cross sections with respect to the invariant mass, the transverse momentum and the rapidity as well as the specific angular correlation between the produced leptons. The numerical results are compared with the experimental data, in different energies, which are reported by various collaborations, such as CDF, CMS, ATLAS and LHCb. It is shown that the NLO-MRW and KMR schemes predict closer results to the data compared to the LO-MRW, since we do not have fragmentation.

description: We propose an experimental scheme to study spin-orbit coupling effects in a of two-dimensional (2D) Fermi atomic gas cloud by coupling its internal electronic states (pseudospins) to radiation in a delta configuration. The induced spin-orbit coupling can be of the Dresselhaus and Rashba type with and without a Zeeman term. We show that the optically induced spin-orbit coupling can lead to a spin-dependent effective mass under appropriate condition, with one of them able to be tuned between positive and negative effective mass. As a direct observable we show that in the expansion dynamics of the atomic cloud the initial atomic cloud splits into two clouds for the positive effective mass case regime, and into four clouds for the negative effective mass regime.

description: The restoration work in Pergamon focusses on two key monuments of the Ancient City: The Red Hall in the Roman lower town and the Gymnasium at the castle hill of Pergamon. Both structures are of outstanding importance as ancient monuments, but also as utmost components of a future, holistic visitors plan for Pergamon. In the Red Hall works have been carried out since 2006 and started initially with the southern round tower. This was followed in 2009 by the substructures in the southeast corner of the temenos and the reconstruction of a large figural support in the southern courtyard, which was completed in 2013. The work on the substructures is to be continued, at the same time current restoration works on the great basilica and the northern round tower initiated by the Turkish Ministry of Culture are advised by the DAI. In the Gymnasium a new project has been started in 2012 with the aim of consolidating the ruins and removing rubble from the old excavations. This covers parts of the structure and locks the ancient road adjoining the Gymnasium, a significant impairment for the visit of the town hill. The mound has already been largely removed and parts of the structure have been preserved. The worked sections provide a some signaling effect, while a consinderbale part still needs to be done.

description: While memory corruption bugs stemming from the use of unsafe programming languages are an old and well-researched problem, the resulting vulnerabilities still dominate real-world exploitation today. Various mitigations have been proposed to alleviate the problem, mainly in the form of language dialects, static program analysis, and code or binary instrumentation. Solutions like AdressSanitizer (ASan) and Softbound/CETS have proven that the latter approach is very promising, being able to achieve memory safety without requiring manual source code adaptions, albeit suffering substantial performance and memory overheads. While performance overhead can be seen as a flexible constraint, extensive memory overheads can be prohibitive for the use of such solutions in memory-constrained environments. To address this problem, we propose MESH, a highly memory-efficient safe heap for C/C++. With its constant, very small memory overhead (configurable up to 2 MB on x86-64) and constant complexity for pointer access checking, MESH offers efficient, byte-precise spatial and temporal memory safety for memory-constrained scenarios. Without jeopardizing the security of safe heap objects, MESH is fully compatible with existing code and uninstrumented libraries, making it practical to use in heterogeneous environments. We show the feasibility of our approach with a full LLVM-based prototype supporting both major architectures, i.e., x86-64 and ARM64, in a Linux runtime environment. Our prototype evaluation shows that, compared to ASan and Softbound/CETS, MESH can achieve huge memory savings while preserving similar execution performance.

description: We study the transport properties of two double quantum dots in a parallel arrangement at temperatures of a few Kelvin. Thereby, we show that decoherence entailed by the substrate phonons affects the shot noise. For asymmetric coupling between the dots and the respective lead, the current noise is sub-Poissonian for resonant tunneling, but super-Poissonian in the vicinity of the resonances. Our results indicate that phonon emission and absorption is responsible for the shot noise enhancement. The observed asymmetry of the peaks at low temperatures stems from spontaneous emission.

description: The concept of exceptional point of degeneracy (EPD) is used to conceive a degenerate synchronization regime that is able to enhance the level of output power and power conversion efficiency for backward wave oscillators (BWOs) operating at millimeter-wave and Terahertz frequencies. Standard BWOs operating at such high frequency ranges typically generate output power not exceeding tens of watts with very poor power conversion efficiency in the order of 1%. The novel concept of degenerate synchronization for the BWO based on a folded waveguide is implemented by engineering distributed gain and power extraction along the slow-wave waveguide. The distributed power extraction along the folded waveguide is useful to satisfy the necessary conditions to have an EPD at the synchronization point. Particle-in-cell (PIC) simulation results shows that BWO operating at an EPD regime is capable of generating output power exceeding 3 kwatts with conversion efficiency of exceeding 20% at frequency of 88.5 GHz.

description: We suggest a better mathematical method, fractional calculus, for studying the behavior of the atom-field interaction in photonic crystals. By studying the spontaneous emission of an atom in a photonic crystal with one-band isotropic model, we found that the long-time inducing memory of the spontaneous emission is a fractional phenomenon. This behavior could be well described by the fractional calculus. And the results show no steady photon-atom bound state for the atomic resonant transition frequency lying in the proximity of allowed band edge which is encountered in the previous study [J. Opt. B: Quantum Semiclass. Opt. {\bf 5}, R43 (2003)]. The correctness of this result is validated by the ``cut-off smoothing'' density of photon states (DOS) with fractional calculus. By obtaining a rigorous solution without the multiple-valued problem for the system, we show the method of fractional calculus has logically concise property.

description: The field campaigns in the Jach-Su valley (South Tajikistan) in 2012 and 2013 shed new light on the settlement history of the end of the 3rd and 2nd millennium BC, on the beginning of the Bronze Age occupation and especially on the transition to the Iron Age. The excavation in the necropoles of Gelot made it possible to reveal a burial complex contemporary with or earlier than the Bactria-Margiana Archaeological Complex. During a survey of the northern Jach-Su valley in 2010, a Bronze Age settlement was discovered on a loess terrace in Saridjar, 20 km to the north-east of Gelot. Excavations in 2012 and in 2013 prove that we are dealing with a 200 × 200 m large settlement with at least three building phases. Excavations on the site of Karimberdy were reopened in 2012 and 2013. Here, pits and pit houses were found which belong to the Early Iron Age.
Perceived change processes in an affective systemic couples therapy
Creators: name: James, Paul Sowden
Publisher: name: University of British Columbia
Year: 2010

description: This study was designed to discover empirically derived categories of couples change processes in an integrated affective systemic couples treatment from the couples perspective, and to refine Greenberg and Johnson's (in press) theoretical model of change processes in the light of these processes. An exploratory and descriptive technique, the critical incident technique, was used to collect critical incidents or descriptions of change events from the perspective of each partner of 21 couples who had experienced significant change in a brief affective systemic couples treatment vis a vis a wait-list control group. These incidents were then analyzed by means of a categorization methodology, the data analytic component of which is called Latent Partition Analysis (LPA). The five empirically derived categories of change processes that emerged from LPA were named (1) emotional experiencing leads to change in interpersonal perceptions, (2) the disclosure of feelings and needs, (3) understanding, (4) taking responsibility for experience, and (5) validation. Given the exploratory and descriptive nature of this study, these processes constitute an initial model that needs to be tested using appropriate methods of verification. Of the five empirically derived change processes, the first change process, which indicates that often clients report that emotional experiencing in their partners modified their perception of their partners, would seem clinically to be the most compelling. Because, unlike the other four processes, the first change process is not discussed in the literature, it would also seem to constitute the most interesting change process as possible new knowledge. Finally, an interview questionnaire, which indicates that partners perceived the expression of feelings to be important in change, lent support to the role of emotion in couples change; the five empirically derived change processes were compared with Greenberg and Johnson's (in press) theoretical model of change processes in order to produce a revised theoretical model.

description: We present a thorough theoretical assessment of the stability of non-collinear spin arrangements in small palladium clusters. We generally find that ferromagnetic order is always preferred, but that antiferromagnetic and non-collinear configurations of different sorts exist and compete for the first excited isomers. We also show that the ground state is insensitive to the choice of atomic configuration for the pseudopotential used and to the approximation taken for the exchange and correlation potential. Moreover, the existence and relative stability of the different excited configurations also depends weakly on the approximations employed. These results provide strong evidence on the transferability of pseudopotential and exchange and correlation functionals for palladium clusters as opposed to the situation found for the bulk phases of palladium.

We prove that the components of $m$ behave as fractional powers of $z$ in the neighbourhood of zero and show that the self-consistent density of states $ρ(E)$ behaves as $\vert E\vert^{-\frac{n-1}{n+1}}$ as $E$ tends to zero, where $n^2$ is a number of blocks. Both constant block and non-constant block cases are considered. In the non-constant case uniform estimates for the components of $m$ are obtained.

description: Fracture involves interaction across large and small length scales. With the application of enough stress or strain to a brittle material, atomistic scale bonds will break, leading to fracture of the macroscopic specimen. From the perspective of mechanics fracture should appear as an emergent phenomena generated by a continuum field theory eliminating the need for a supplemental kinetic relation describing crack growth. We develop a new fast method for modeling quasi-static fracture using peridynamics. We apply fixed point theory and model stable crack evolution for hard and soft loading. For soft loading we recover unstable fracture. For hard loading we recover stable crack growth. We show existence of quasistatic fracture solutions in the neighborhood of stable critical points for appropriately defined energies. The numerical method uses an analytic stiffness matrix for fast numerical implementation. A rigorous mathematical analysis shows that the method converges for load paths associated with soft and hard loading. For soft loading the crack becomes unstable shortly after the stress at the tip of the pre-crack reaches the material strength.

description: We complete the program of 2012.15792 about perturbative approaches for $\mathcal{N}=2$ superconformal quiver theories in four dimensions. We consider several classes of observables in presence of Wilson loops, and we evaluate them with the help of supersymmetric localization. We compute Wilson loop vacuum expectation values, correlators of multiple coincident Wilson loops and one-point functions of chiral operators in presence of them acting as superconformal defects. We extend this analysis to the most general case considering chiral operators and multiple Wilson loops scattered in all the possible ways among the vector multiplets of the quiver. Finally, we identify twisted and untwisted observables which probe the orbifold of $AdS_5\times S^5$ with the aim of testing possible holographic perspectives of quiver theories in $\mathcal{N}=2$.

description: The main importance of sanctuaries for the community of Kanatha can be seen in their various functions. As centres of the public life they fulfilled religious, social, trade, therapeutic and personal needs of the local community. Moreover, they had privileges such as tax exemption and the right of asylum. It appears that some of the sanctuaries were in charge of the water supply thus securing a vital resource gradually turning them into some of the most important buildings of the settlement.

description: The project deals with the remains of a church built in late antiquity, located at ‚La Losilla‘ near the village of Añora (Córdoba) in Andalusia. Beside the remainder of the church itself, particularly the necropolis is noteworthy. One significant aim of the project is to examine by archaeological means the context in which the church was built and used. The venture was started in early 2013 and will be pursued at least until autumn 2016. This article gives a résumé of the results gained during the campaign of 2013.

description: Aims: We wish to investigate what the effect of dust sedimentation is on the observed 10 mum feature of protoplanetary disks and how this may affect the interpretation of the observations. Methods: Using a combination of modeling tools, we simulated the sedimentation of a dust grain size distribution in an axisymmetric 2-D model of a turbulent protoplanetary disk, and we used a radiative transfer program to compute the resulting spectra. Results: We find that the sedimentation can turn a flat feature into a pointy one, but only to a limited degree and for a very limited set of particle size distributions. Only if we have a bimodal size distribution, i.e. a very small grain population and a bigger grain population, do we find that the transformation from a flat to a pointy feature upon dust sedimentation is strong. However, our model shows that, if sedimentation is the sole reason for the variety of silicate feature strengths observed in protoplanetary disks, then we would expect to find a correlation such that disks with weak mid- to far-infrared excess have a stronger 10 mum silicate feature than disks with a strong mid- to far-infrared excess. If this is contrary to what is observed, then this would indicate that sedimentation cannot be the main reason for the variety of 10 mum silicate features observed in protoplanetary disks.

description: The international and multidisciplinary joint project in South Russia, initiated in 2006, changed the existing reconstruction of the ancient topography and geology of the Taman Peninsula. Furthermore, excavations in selected locations east of the strait of Kerč indicate that the Greek colonization probably had started further in the East than previously thought. Therefore, the process of Greek colonization in the Bosporus must be reconsidered not only in its dating but even more in its geographical extension.

description: Second-order nonlinear effects, such as second-harmonic generation, can be strongly enhanced in nanofabricated photonic materials when both fundamental and harmonic frequencies are spatially and temporally confined. Practically designing low-volume and doubly resonant nanoresonators in conventional semiconductor compounds is challenging owing to their intrinsic refractive index dispersion. In this work we review a recently developed strategy to design doubly resonant nanocavities with low mode volume and large quality factor by localized defects in a photonic crystal structure. We build on this approach by applying an evolutionary optimisation algorithm in connection with Maxwell equations solvers, showing that the proposed design recipe can be applied to any material platform. We explicitly calculate the second-harmonic generation efficiency for doubly resonant photonic crystal cavity designs in typical III-V semiconductor materials, such as GaN and AlGaAs, targeting a fundamental harmonic at telecom wavelengths, and fully accounting for the tensor nature of the respective nonlinear susceptibilities. These results may stimulate the realisation of small footprint photonic nanostructures in leading semiconductor material platforms to achieve unprecedented nonlinear efficiencies.

description: Using a hydrodynamics plus N-body simulation of galaxy cluster formation within a large volume and mock Chandra X-ray observations, we study the form and evolution of the intrinsic scatter about the best-fit X-ray temperature-mass relation for clusters. We investigate the physical origin of the scatter by correlating it with quantities that are closely related to clusters' formation and merging histories. We also examine the distribution of the scatter for merging and nonmerging populations, identified using halo merger trees derived from the simulation as well as X-ray substructure measures. We find a strong correlation between the scatter in the M-T_X relation and the halo concentration, in the sense that more concentrated clusters tend to be cooler than clusters with similar masses. No bias is found between the merging and relaxed clusters, but merging clusters generally have greater scatter, which is related to the properties of the distribution of halo concentrations. We also detect a signature of non-lognormality in the distribution of scatter for our simulated clusters both at z=0 and at z=1. A detailed comparison of merging clusters identified by substructure measures and by halo merger trees is given in the discussion. We conclude that, when cooling-related effects are neglected, the variation in halo concentrations is a more important factor for driving the intrinsic scatter in the M-T_X relation, while departures from hydrostatic equilibrium due to cluster mergers have a minor effect.

description: We present the first 850 $μ$m polarization observations in the most active star-forming site of the Rosette Molecular Cloud (RMC, $d\sim$1.6 kpc) in the wall of the Rosette Nebula, imaged with the SCUBA-2/POL-2 instruments of the JCMT, as part of the B-Fields In Star-Forming Region Observations 2 (BISTRO-2) survey. From the POL-2 data we find that the polarization fraction decreases with the 850 $μ$m continuum intensity with $α$ = 0.49 $\pm$ 0.08 in the $p \propto I^{\rm -α}$ relation, which suggests that some fraction of the dust grains remain aligned at high densities. The north of our 850 $μ$m image reveals a "gemstone ring" morphology, which is a $\sim$1 pc-diameter ring-like structure with extended emission in the "head" to the south-west. We hypothesize that it might have been blown by feedback in its interior, while the B-field is parallel to its circumference in most places. In the south of our SCUBA-2 field the clumps are apparently connected with filaments which follow Infrared Dark Clouds (IRDCs). Here, the POL-2 magnetic field orientations appear bimodal with respect to the large-scale Planck field. The mass of our effective mapped area is $\sim$ 174 $M_\odot$ that we calculate from 850 $μ$m flux densities. We compare our results with masses from large-scale emission-subtracted Herschel 250 $μ$m data, and find agreement within 30%. We estimate the POS B-field strength in one typical subregion using the Davis-Chandrasekhar-Fermi (DCF) technique and find 80 $\pm$ 30 $μ$G toward a clump and its outskirts. The estimated mass-to-flux ratio of $λ$ = 2.3 $\pm$ 1.0 suggests that the B-field is not sufficiently strong to prevent gravitational collapse in this subregion.

description: Cyclobutane is a cycloalkane and organic compound. Cyclobutane is a colourless gas and commercially available as a liquefied gas. Derivatives of cyclobutane are called cyclobutanes. Cyclobutane itself is of no commercial significance. The bond angles between carbon atoms are significantly strained and as such have lower bond energies than related linear or unstrained hydrocarbons, for example, butane or cyclohexane. The four carbon atoms in cyclobutane are not coplanar; instead, the ring typically adopts a folded or "puckered" conformation. This implies that the carbon-carbon-carbon angle is less than 90°. One of the carbon atoms makes a 25° angle with the plane formed by the other three carbons. In this way some of the eclipsing interactions are reduced. The conformation is also known as a "butterfly". Equivalent puckered conformations interconvert.

description: The joint project conducted by the Eurasia Department and the Institute for Prehistoric Archaeology of FU Berlin together with scholars from the Republic of Moldova and the Ukraine is devoted to the investigation of the early Copper Age culture system in the steppes of the north-western Black Sea, an area that owing to its geo-strategical position was predestined to become a contact zone between two cultural spheres in prehistory: sedentary and mobile cultures. The investigations focus on the interactions between the sedentary Bolgrad-Aldeni culture and the mobile sceptre-bearing groups, interactions that marked the development of the local early Copper Age and at the same time embody the first hitherto known cultural contacts within the above-named geocultural framework. Thanks to the outstanding participative work the above named colleagues, an interdisciplinary research project could be established, which embraces the fields of archaeology, climatology, archaeobotany, archaeozoology and anthropology. The results gained from these undertakings have enabled the research team to largely accomplish the endeavours of investigating the culture historical relevance of the settlement of Orlovka-Kartal, and to address complex of questions concerning the role played by the northwestern Black Sea area in the context of the emergence and development of the European Copper Age.

description: By a proper choice of the excitation energy per nucleon we analyze the mass distributions of the nuclear fragmentation at various excitation energies. Starting from low energies (between 0.1 and 1 MeV/nucleon) up to higher energies about 12 MeV/n, we classified the mass yield characteristics for heavy nuclei (A>200) on the basis of Statistical Multifragmentation Model. The evaluation of fragment distribution with the excitation energy show that the present results exhibit the same trend as the experimental ones.

description: The Chalcolithic – Early Bronze Age tells of Hujayrat al-Ghuzlan and al-Magass are situated at the northern fringe of the modern town of Aqaba in southern Jordan. At both sites systematic archaeological research has taken place since excavations by Lutfi Khalil (University of Jordan) started in 1985. In 1998 the ASEYM project (Archaeological Survey and Excavation in the Yitim and Magaṣṣ Area) was established as a cooperation between the University of Jordan and the Orient Department of the DAI, continuing this previous research. The major focus of the field work in 2013 was on the documentation of the western section of Tall al-Magass, a deep profile being the result of road construction work in 1967.
