description: Kurumsal Yönetim (corporate governance) şirketlerin yönetimi ile sahipliği ayrıldığından beri ortaya çıkan vekâlet sorununun (agency problem) nasıl izale edileceğine ilişkin gösterilen çabaların ortak adı olup, şirketleşmenin tarihi kadar eskidir. Liberal ekonomi politikalarının dünyada yaygınlaşmasının neticesinde serbest piyasa ekonomisinin merkezine yerleşen dev şirketlerin nasıl idare olunacağı sadece ortakların veya yöneticilerin değil, ekonomik istikrarı bozma tehdidine karşı, bütün bir toplumun meselesi haline gelmiştir. 1990’lı yıllardan itibaren önce İngiltere’de hazırlanan raporlarla popülerleşen kurumsal yönetim çalışmaları OECD gibi uluslararası kurumların da desteği ile küresel olarak yaygınlaşmıştır. Başlangıçta şirketleri dizginlemek için getirilen ilkeler, şirket skandallarının sayısı ve boyutu arttıkça yumuşak kurallardan saha sert düzenlemelere doğru evrilmiştir. Her ülke kendi kurumsal yönetim iklimini oluştursa da, kurumsal yönetim çalışmalarının şirketleri daha demokratik, hesap verebilir, şeffaf ve dürüst hale getirme hedefleri ortaktır. Bu hedeflere ulaşmak için getirilecek ilkeler, kurallar kurumsal yönetim çalışmalarının konusunu oluşturmaktadır.

description: Activity recognition from sensor data deals with various challenges, such as overlapping activities, activity labeling, and activity detection. Although each challenge in the field of recognition has great importance, the most important one refers to online activity recognition. The present study tries to use online hierarchical hidden Markov model to detect an activity on the stream of sensor data which can predict the activity in the environment with any sensor event. The activity recognition samples were labeled by the statistical features such as the duration of activity. The results of our proposed method test on two different datasets of smart homes in the real world showed that one dataset has improved 4% and reached (59%) while the results reached 64.6% for the other data by using the best methods.

description: The role of national cinema in shaping, reflecting and contesting a complex national identity that is the site of conflict and struggle is the central interest of this study of contemporary Peruvian cinema, 1988-2004. This project examines the relationship between cinema, state and identity in Peru, with a specific focus on the representation of the political violence between the state and Sendero Luminoso (Shining Path) that began in 1980. It looks in particular at portrayals of important events, characters and consequences of the bloody conflict that for a time threatened to destabilize the nation entirely. It considers these representations in the context of a time of great change for Peruvian society and of transition for Peruvian national cinema, and addresses the relationship between developments in film policy and the formation of Peruvian national identity in cinema. As such, it draws on debates about the nature and function of national cinemas, as well as on discussions between artists, cultural theorists and sociologists about the evolution of peruanidad since the declaration of independence from Spain in the early nineteenth century. Once the main elements of the cinematic and social crises have been explored and established in Chapters Two and Three, the remainder of the project consists of three sets of chronologically ordered analyses of individual films that somehow defied the national cinema crisis, and that provoked debate on both the conflict itself, and on broader questions pertaining to the relationship between national identity and violence. The conclusion considers these films as an interlinked body of cinematic works that share similar themes and concerns. It summarises the issues they tackle, the ideological and formal approaches they take to those issues, the potential social and cultural impact, and their contribution to the crystallization of a Peruvian national identity at the start of the twenty-first century.

description: We review a model--based rather than phenomenological approach to low--temperature anomalies in glasses. Specifically, we present a solvable model inspired by spin--glass theory that exhibits both, a glassy low--temperature phase, and a collection of double-- and single--well configurations in its potential energy landscape. The distribution of parameters characterizing the local potential energy configurations can be computed, and is found to differ from those assumed in the standard tunneling model and its variants. Still, low temperature anomalies characteristic of amorphous materials are reproduced. More importantly perhaps, we obtain a clue to the universality issue. That is, we are able to distinguish between properties which can be expected to be universal and those which cannot. Our theory also predicts the existence, under suitable circumstances of amorphous phases without low--energy tunneling excitations.

description: The two-time Green function method is employed to explore the effect of the biquadratic exchange interaction on the phase diagram of a $d$-dimensional spin-1 transverse XY model with single-ion anisotropy close to the magnetic-field-induced quantum critical point. We work at level of the Anderson-Callen-decoupling-like framework for both easy-plane and easy-axis single-ion anisotropy. The structure of the phase diagram is analyzed with analytical estimates and numerical calculations by adopting Tyablikov-like decouplings for the exchange higher order Green functions in the equation of motion. For dominant bilinear short-range exchange interaction the structure of the phase diagram close to the quantum critical point remains qualitatively the same of that in absence of biquadratic interaction including reentrant critical lines. When the biquadratic exchange becomes increasingly dominant its role appears more effective and tends to reduce or destroy the reentrant character of the critical lines.

description: Large-area high density patterns of quantum dots with a diameter of 200 nm have been prepared from a series of four Zn_{0.93}Mn_{0.07}Te/ZnTe multiple quantum well structures of different well width (4 nm, 6 nm, 8 nm and 10 nm) by electron beam lithography followed by Ar+ ion beam etching. Below-bandgap photomodulated reflectivity spectra of the quantum dot samples and the parent heterostructures were then recorded at 10 K and the spectra were fitted to extract the linewidths and the energy positions of the excitonic transitions in each sample. The fitted results are compared to calculations of the transition energies in which the different strain states in the samples are taken into account. We show that the main effect of the nanofabrication process is a change in the strain state of the quantum dot samples compared to the parent heterostructures. The quantum dot pillars turn out to be freestanding, whereas the heterostructures are in a good approximation strained to the ZnTe lattice constant. The lateral size of the dots is such that extra confinement effects are not expected or observed.

description: A primary pseudoperfect number (PPN) is an integer $K > 1$ such that the reciprocals of $K$ and its prime factors sum to 1. PPNs arise in studying perfectly weighted graphs and singularities of algebraic surfaces, and are related to Sylvester's sequence, Giuga numbers, Znám's problem, the inheritance problem, and Curtiss's bound on solutions of a unit fraction equation. Here we show $K \equiv 6 \pmod{6^2}$ if $6\mid K$, and uncover a remarkable $7$-term arithmetic progression of residues modulo $6^2\cdot8$ in the sequence of known PPNs. On that basis, we pose a conjecture which leads to a conditional proof of the new record lower bound $k>10^{3.99\times10^{20}}$ on any non-trivial solution to the Erdős-Moser Diophantine equation $1^n + 2^n + \dotsb + k^n = (k+1)^n$.

description: Phase transitions of small isolated systems are signaled by the shape of the caloric equation of state e^*(T), the relationship between the excitation energy per nucleon e^* and temperature. In this work we compare the experimentally deduced e^*(T) to the theoretical predictions. The experimentally accessible temperature was extracted from evaporation spectra from incomplete fusion reactions leading to residue nuclei. The experimental e^*(T) dependence exhibits the characteristic S-shape at e^* = 2-3 MeV/A. Such behavior is expected for a finite system at a phase transition. The observed dependence agrees with predictions of the MMMC-model, which simulates the total accessible phase-space of fragmentation.
Studentsâ€™ predictions in novel situations and the role of self-generated analogies in their reasoning

description: This cross age study was designed to investigate studentsâ€™ predictions in novel situations and the role that self-generated analogies play in non-scientific reasoning. The study used a mixed method ap-proach. Data was collected through the conduction of group interviews which were audio-tape rec-orded and additional data was collected through the use of written responses in the questionnaire. There were 37, 31, 29, 35 and 34 students recruited from Year 4, Year 6, Year 7, Year 9 and Year 11 (aged 9-10, 11-12, 12-13. 14-15 and 16-17 years) respectively from ten different schools in Greece. Studentsâ€™ responses were analysed to ascertain whether their predictions drew on the use of analogies, and if so, the nature of the analogies that they used and whether the ideas used in the explanations of their predictions could be understood from a p-prims or a misconception perspective. The study found that students regularly make use of analogies, rather than scientific thinking in order to make their predictions. It also emerged that there were many similarities among studentsâ€™ predic-tions as well as the analogies they used to explain the latter. In many cases this studentsâ€™ non-scientific reasoning was based on their experiential knowledge which led them to make a prediction which is not compatible with the scientific view. However, according to the findings, there were cases in which analogical reasoning led some of them, more frequently the older (secondary education) ones, to make correct predictions. The study suggests that teachers need to be more aware of the nature of the analogies used and how, and why, these analogies can, in many cases, lead students to make scientifically incorrect or correct predictions.

description: A five dimensional brane cosmology with non-minimally coupled scalar field to gravity has been considered in a Jordan-Brans-Dicke frame. We derive an effective four dimensional field equations on a 3+1 dimensional brane where the fifth dimension has been assumed to have an orbifold symmetry. We have noticed that the evolution equation for the matter component stuck to the brane is non-trivially coupled to the scalar field living on the brane and the bulk. Finally we discuss some cosmological consequences of this set-up.

Multiple scattering of classical waves: from microscopy to mesoscopy and diffusion

Publisher: name: arXiv

Subjects: subject: Mesoscale and Nanoscale Physics (cond-mat.mes-hall)

description: A tutorial discussion of the propagation of waves in random media is presented. In first approximation the transport of the multiple scattered waves is given by diffusion theory, but important corrections are present. These corrections are calculated with the radiative transfer or Schwarzschild-Milne equation, which describes intensity transport at the ``mesoscopic'' level and is derived from the ``microscopic'' wave equation. A precise treatment of the diffuse intensity is derived which automatically includes the effects of boundary layers. Effects such as the enhanced backscatter cone and imaging of objects in opaque media are also discussed within this framework. In the second part the approach is extended to mesoscopic correlations between multiple scattered intensities which arise when scattering is strong. These correlations arise from the underlying wave character. The derivation of correlation functions and intensity distribution functions is given and experimental data are discussed. Although the focus is on light scattering, the theory is also applicable to micro waves, sound waves and non-interacting electrons.

description: Automatic lesion detection from computed tomography (CT) scans is an important task in medical imaging analysis. It is still very challenging due to similar appearances (e.g. intensity and texture) between lesions and other tissues, making it especially difficult to develop a universal lesion detector. Instead of developing a specific-type lesion detector, this work builds a Universal Lesion Detector (ULDor) based on Mask R-CNN, which is able to detect all different kinds of lesions from whole body parts. As a state-of-the-art object detector, Mask R-CNN adds a branch for predicting segmentation masks on each Region of Interest (RoI) to improve the detection performance. However, it is almost impossible to manually annotate a large-scale dataset with pixel-level lesion masks to train the Mask R-CNN for lesion detection. To address this problem, this work constructs a pseudo mask for each lesion region that can be considered as a surrogate of the real mask, based on which the Mask R-CNN is employed for lesion detection. On the other hand, this work proposes a hard negative example mining strategy to reduce the false positives for improving the detection performance. Experimental results on the NIH DeepLesion dataset demonstrate that the ULDor is enhanced using pseudo masks and the proposed hard negative example mining strategy and achieves a sensitivity of 86.21% with five false positives per image.

description: Landau levels (LL) have been predicted to emerge in systems with Dirac nodal points under applied non-uniform strain. We consider 2D, $d_{xy}$ singlet (2D-S) and 3D $p \pm i p$ equal-spin triplet (3D-T) superconductors (SCs). We demonstrate the spinful Majorana nature of the bulk gapless zeroth-LLs. Strain along certain directions can induce two topologically distinct phases in the bulk, with zeroth LLs localized at the the interface. These modes are unstable toward ferromagnetism for 2D-S cases. Emergent real-space Majorana fermions in 3D-T allow for more exotic possibilities.

description: Based on the context of complexity = action (CA) conjecture, we calculate the holographic complexity of AdS black holes with planar and spherical topologies in Horndeski theory. We find that the rate of change of holographic complexity for neutral AdS black holes saturates the Lloyd's bound. For charged black holes, we find that there exists only one horizon and thus the corresponding holographic complexity can't be expressed as the difference of some thermodynamical potential between two horizons as that of Reissner-Nordstrom AdS black hole in Einstein-Maxwell theory. However, the Lloyd's bound is not violated for charged AdS black hole in Horndeski theory.

description: Colossal negative magnetoresistance Δρ(T,B) observed in La(0.6)Y(0.1)Ca(0.3)MnO(3) at B=1T shows a nearly perfect symmetry around T_0=160K suggesting a universal field-induced transport mechanism in this material. Attributing this symmetry to strong magnetic fluctuations (triggered by the Y substitution and further enhanced by magnetic field, both above and below the field-dependent Curie temperature T_C(B)=T_0), the data are interpreted in terms of the nonthermal spin hopping and magnetization M dependent charge carrier localization scenario leading to Δρ(T,B)= -ρ_s(1-exp(-γM^2)) with M(T,B)=CB/|T-T_C|^n. The separate fits through all the data points above and below T_C yield C^{+}\simeq C^{-} and n^{+}\simeq n^{-}\simeq 1. The obtained results corroborate the importance of fluctuation effects in this material recently found (cond-mat/9812219) to dominate its magneto-thermopower behavior far beyond T_C.

description: We point out the existence of new effects of global spacetime expansion on local binary systems. In addition to a possible change of orbital size, there is a contribution to the precession of elliptic orbits, to be added to the well-known general relativistic effect in static spacetimes, and the eccentricity can change. Our model calculations are done using geodesics in a McVittie metric, representing a localized system in an asymptotically Robertson-Walker spacetime; we give a few numerical estimates for that case, and indicate ways in which the model should be improved.

description: Time-continuous emotion prediction has become an increasingly compelling task in machine learning. Considerable efforts have been made to advance the performance of these systems. Nonetheless, the main focus has been the development of more sophisticated models and the incorporation of different expressive modalities (e. g., speech, face, and physiology). In this paper, motivated by the benefit of difficulty awareness in a human learning procedure, we propose a novel machine learning framework, namely, Dynamic Difficulty Awareness Training (DDAT), which sheds fresh light on the research -- directly exploiting the difficulties in learning to boost the machine learning process. The DDAT framework consists of two stages: information retrieval and information exploitation. In the first stage, we make use of the reconstruction error of input features or the annotation uncertainty to estimate the difficulty of learning specific information. The obtained difficulty level is then used in tandem with original features to update the model input in a second learning stage with the expectation that the model can learn to focus on high difficulty regions of the learning process. We perform extensive experiments on a benchmark database (RECOLA) to evaluate the effectiveness of the proposed framework. The experimental results show that our approach outperforms related baselines as well as other well-established time-continuous emotion prediction systems, which suggests that dynamically integrating the difficulty information for neural networks can help enhance the learning process.

description: Climate adaptation and emergency management in cities present significant challenges that can be addressed through the incorporation of real-time weather, air quality, exposure, and vulnerability data. However, existing commercial sensor network solutions often lack the necessary characteristics and wide spectrum of observed variables require to map average conditions and weather extremes at the street-level, capturing intra-urban variabilities and microclimates that directly impact people. In response, we have developed a custom two-tiered sensor system, deployed on city-owned street lights in Freiburg, Germany. The system currently consists of 13 self-developed "Tier-I stations" and 29 commercial "Tier-II stations" (LoRAIN NBIoT, Pessl Instruments GmbH), aimed at providing a modular, user-friendly Wireless Sensor Network (WSN) with high spatial density and temporal resolution for research and public use. Our Tier-I stations were designed from the ground up, including the printed circuit board (PCB), to support temporally high-resolution WSNs, to accommodate a wide range of sensors, and to allow for expandability. The setup is easily expandable through the addition of predefined sensors to a configuration file, and each station seamlessly integrates itself with the server and other processes. Remote access, bidirectional communication, and task distribution protocols further enhance system modularity and ease of maintenance. In addition to air temperature, humidity and precipitation measured by the Tier II stations, the Tier-I station feature a ClimaVUE 50 all-in-one weather sensor and a BlackGlobe (Campbell Scientific, Inc.) that provides data on wind, radiation, pressure, lightning, solar radiation and black globe temperatures which allows for real-time calculation of thermal comfort indices. The near-real-time data can be accessed through our self-developed "uniWeather" iOS app and API, facilitating data-driven decision-making and public outreach. In addition, we will discuss the spatiotemporal heat stress patterns in Freiburg based on the first full year of measurements at one-minute resolution.

description: The hybrid runtime (HRT) model offers a path towards high performance and efficiency. By integrating the OS kernel, runtime, and application, an HRT allows the runtime developer to leverage the full feature set of the hardware and specialize OS services to the runtime's needs. However, conforming to the HRT model currently requires a port of the runtime to the kernel level, for example to the Nautilus kernel framework, and this requires knowledge of kernel internals. In response, we developed Multiverse, a system that bridges the gap between a built-from-scratch HRT and a legacy runtime system. Multiverse allows unmodified applications and runtimes to be brought into the HRT model without any porting effort whatsoever by splitting the execution of the application between the domains of a legacy OS and an HRT environment. We describe the design and implementation of Multiverse and illustrate its capabilities using the massive, widely-used Racket runtime system.

description: Studies of how protein fold have shown that the way protein clumps form in the test tube is similar to how proteins form the so-called ``amyloid'' deposits that are the pathological signal of a variety of diseases, among them the memory disorder Alzheimer's. Protein aggregation have traditionally been connected to either unfolded or native states. Inclusion body formation (disordered aggregation) has been assumed to arise from hydrophobic aggregation of the unfolded or denaturated states, while the amyloid fibrils (ordered aggregation) have been assumed to arise from native-like conformations in a process analogous to the polymerization of hemoglobin S. Making use of lattice-model simulations we find that both ordered and disordered aggregation arise from elementary structures which eventually build the folding nucleus of the heteropolymers, and takes place when some of the most strongly interacting amino acids establish their contacts leading to the formation of a specific subset of the native structure. These elementary structures can be viewed as the partially folded intermediates suggested to be involved in the aggregation of a number of proteins. These results have evolutionary implications, as the elementary structures forming the folding core of designed proteins contain the residues which are conserved among the members of homologous sequences.

On the Variation in Mode Choice Behavior in Agent-based Travel Demand Models

description: Past research shows that individual mode choice preferences and, thus, taste variation of mode choice play an essential role and are observable even for one day. Both multiand monomodal behavioral patterns with different degrees of mode choice variation are the subject of investigation. Hence, agent-based travel demand models (AB-TDMs) must account for this taste variation, which is expected to affect model sensitivity. To assess the impacts of mode choice model configuration on the resulting variation, we apply an approach based on mixed logit models and implement them in an AB-TDM simulation. We analyze the mode choice behavior regarding variation indicators for the simulation period of one day and one week and compare it to observed behavior. We show that classic MNL models cannot appropriately account for mode choice variation in AB-TDM, both for one week or one day. We show that mixed model approaches can bridge this gap by better capturing heterogeneity and suggest using mixed models in an agent-based context. This prevents models from overestimating multimodal mode choice behavior.

description: We investigate the dynamical processes taking place in nanodevices driven by high-frequency electromagnetic fields. We want to elucidate the role of different mechanisms that could lead to loss of quantum coherence. Our results show how the dephasing effects of disorder that destroy after some periods coherent oscillations, such as Rabi oscillations, can be overestimated if we do not consider the electron-electron interactions that can reduce dramatically the decoherence effects of the structural imperfections. Experimental conditions for the observation of the predicted effects are discussed.

description: Black holes have their own thermodynamics including notions of entropy and temperature and versions of the three laws. After a light introduction to black hole physics, I recollect how black hole thermodynamics evolved in the 1970's, while at the same time stressing conceptual points which were given little thought at that time, such as why the entropy should be linear in the black hole's surface area. I also review a variety of attempts made over the years to provide a statistical mechanics for black hole thermodynamics. Finally, I discuss the origin of the information bounds for ordinary systems that have arisen as applications of black hole thermodynamics.

description: El Grupo Operativo Innoland publica esta Letter como información básica que justifica emprender Iniciativas de Gestión Común (IGC) en las cooperativas que agrupen parcelas y capturen valor añadido para sus socios. Las IGC son un modelo de negocio promovido por el Grupo Operativo INNOLAND. El estudio utiliza datos de la Encuesta de Estructuras Agrarias de Instituto Nacional de Estadística para documentar cómo el tamaño de las explotaciones especializadas en un cultivo concreto influye en la intensidad de utilización de trabajo por hectárea. La reducción de la intensidad de mano de obra no es un objetivo per se, pero la mayor eficiencia de las explotaciones no está reñida con la ganancia de valor añadido. El crecimiento del tamaño de las explotaciones persigue diferentes objetivos, todos ellos bajo un enfoque de un ahorro de costes, vía la aplicación de economías de escala y la mecanización. Una mayor productividad puede comportar unos mejores resultados. En esta Letter nos centramos en el número de UTA (unidades de trabajo-año) por unidad de superficie.

Grover search with pairs of trapped ions

description: The desired interference required for quantum computing may be modified by the wave function oscillations for the implementation of quantum algorithms[Phys.Rev.Lett.84(2000)1615]. To diminish such detrimental effect, we propose a scheme with trapped ion-pairs being qubits and apply the scheme to the Grover search. It can be found that our scheme can not only carry out a full Grover search, but also meet the requirement for the scalable hot-ion quantum computing. Moreover, the ion-pair qubits in our scheme are more robust against the decoherence and the dissipation caused by the environment than single-particle qubits proposed before.

description: Using the method of energy-level statistics, the localization properties of electrons moving in two dimensions in the presence of a perpendicular random magnetic field and additional random disorder potentials are investigated. For this model, extended states have recently been proposed to exist in the middle of the band. In contrast, from our calculations of the large-$s$ behavior of the nearest neighbor level spacing distribution $P(s)$ and from a finite size scaling analysis we find only localized states in the suggested energy and disorder range.

description: In realistic spinglasses, such as CuMn, AuFe and EuSrS, magnetic atoms are located at random positions. Their couplings are determined by their relative positions. For such systems a field theory is formulated. In certain limits it reduces to the Hopfield model, the Sherrington-Kirkpatrick model, and the Viana-Bray model. The model has a percolation transition, while for RKKY couplings the ``concentration scaling'' T_g proportional to c occurs. Within the Gaussian approximation the Ginzburg-Landau expansion is considered in the clusterglass phase, that is to say, for not too small concentrations. Near special points, the prefactor of the cubic term, or the one of the replica-symmetry- breaking quartic term, may go through zero. Around such points new spin glass phases are found.
