Moduli as inflatons in heterotic M-theory

We consider different cosmological aspects of heterotic M-theory. In particular we look at the dynamical behaviour of the two relevant moduli in the theory, namely the length of the eleventh segment (? ) and the volume of the internal six manifold (V) in models where supersymmetry is broken by multiple gaugino condensation. We look at different ways to stabilize these moduli, namely racetrack scenarios with and without non-perturbative corrections to the K? hler potential. The existence of different flat directions in the scalar potential, and the way in which they can be partially lifted, is discussed as well as their possible role in constructing a viable model of inflation. Some other implications such as the status of the moduli problem within these models are also studied.
Horizontal Search Method for Wikipedia Category Grouping

Category hierarchies, which show the basic relationship between concepts, are utilized as fundamental clues for semantic information processing in diverse research fields. These research works have employed Wikipedia due to its high coverage of real-world concepts and data reliability. Wikipedia also constructs a category hierarchy, and defines various categories according to the common characteristics of a concept. However, some limitations have been uncovered in the use of a vertical search (especially top-down) to form a set of domain categories. In order to overcome these limitations, this paper proposes a horizontal search method, and uses Wikipedia components to measure the similarity between categories. In an experimental evaluation, we confirm that our method shows a wide coverage and high precision for similar (domain) category grouping.
Adaptive Backstepping control for MAPK cascade models using RBF neural networks

In this paper, an Adaptive Backstepping Neural Network control approach is used for a class of affine nonlinear systems which describe the Mitogen Activated Protein Kinase (MAPK) cascade models in the strict feedback form. We consider some of forms of the MAPK cascade [4]. The close loop signals are semiglobally uniformly ultimately bounded and the output of the system is proven to follow a desired trajectory. Simulation results are presented to show the effectiveness of the approach proposed in order to control the MAPK output.
A portrait of a Japanese history Professor at Keijo Imperial University, Korea

This essay examines the education and research of Kaneko Gosuke, a western history professor at Keijo Imperial University. Western history was both highly emphasized in the preparatory course and suppressed within Keijo University’s history department due to its double identities, one as a mirror in understanding the world and the Japanese Empire and the other as the explosive charge of threatening concepts like nationalism and democracy. Kaneko Gosuke could teach only introductory courses because western history as a major was not allowed in the university. However, by focusing merely on theoretical topics such as German historicism, Kaneko made his western history education acceptable to the Japanese colonial regime. The research of Kaneko, the only historical researcher in the Korean western history group, can be characterized by its Eurocentrism and its lack of engagement with the temporal and spatial context – that is, a colonized Joseon under Japanese imperial rule. His seemingly apolitical research contributed to an image of the West as a remote “Eldorado,” which could not be reached and to which Koreans were necessarily subordinate. In this way, he might have contributed to the perpetuation of the colonization of Korea.
Are fossil groups a challenge of the cold dark matter paradigm

We study six groups and clusters of galaxies suggested in the literature to be 'fossil' systems (i.e. to have luminous diffuse X-ray emission and a magnitude gap of at least 2 mag R between the first and the second ranked member within half of the virial radius), each having good quality X-ray data and Sloan Digital Sky Survey (SDSS) spectroscopic or photometric coverage out to the virial radius. The poor cluster AWM 4 is clearly established as a fossil system, and we confirm the fossil nature of four other systems (RX J1331.5+1108, RX J1340.6+4018, RX J1256.0+2556 and RX J1416.4+2315), while the cluster RX J1552.2+2013 is disqualified as fossil system. For all systems, we present the luminosity functions within 0.5 and 1 virial radius that are consistent, within the uncertainties, with the universal luminosity function of clusters. For the five bonafide fossil systems, having amass range 2 x 10 13 -3 x 10 14 M ⊙, we compute accurate cumulative substructure distribution functions (CSDFs) and compare them with the CSDFs of observed and simulated groups/clusters available in the literature. We demonstrate that the CSDFs of fossil systems are consistent with those of normal observed clusters and do not lack any substructure with respect to simulated galaxy systems in the cosmological A cold dark matter (ACDM) framework. In particular, this holds for the archetype fossil group RX J1340.6+4018 as well, contrary to earlier claims.
A Theory of Market Transition: From Redistribution to Markets in State Socialism

State socialist redistributive economies are characterized by the allocation and distribution of goods through central planning. This paper develops a theory of market transition which argues that, in reforming socialist economies, the transition from redistributive to market coordination shifts sources of power and privilege to favor direct producers relative to redistributors. The shit improves incentives for direct producers, stimulates the growth of private markets, and provides to entrepreneurs -an alternative path for socioeconomic mobility. A set of hypotheses test the market transition theory with householdand village-level data.
The globular cluster NGC 6642: evidence for a depleted mass function

Abstract We present photometry for the globular cluster NGC 6642 using the F606W and F814W filters with the ACS/WFC third-generation camera aboard the Hubble Space Telescope. The colour–magnitude diagram shows sources reaching ≈ 6 mag below the turnoff in mF606W. Theoretical isochrone fitting was performed and evolutionary parameters were obtained, including the metallicity [Fe/H] = −1.80 ± 0.2 dex and age, log(age/yr) = 10.14 ± 0.05. We confirm that NGC 6642 is located in the Galactic bulge, at a distance of d⊙ = 8.05±0.66 kpc and suffers from a reddening of E(B − V) = 0.46 ± 0.02 mag. These values are in general agreement with those of previous authors. Completeness-corrected luminosity and mass functions were obtained for different annuli centred on NGC 6642. Their spatial variation indicates the existence of mass segregation and depletion of low-mass stars. Most striking is the inverted shape of the mass function itself, with an increase in stellar numbers as a function of increasing mass. This has been observed previously in other globular clusters and is also the result of N-body simulations of stellar systems which have reached ≃90% of their lifetime and are subjected to strong tidal effects. We thus conclude that NGC 6642 is a very old, highly evolved globular cluster. Its current location close to perigalacticon, at only 1.4 kpc from the Galactic Centre, may contribute to this high level of dynamical evolution and stellar depletion.
Real-time collaborative resolving of merge conflicts

Merge conflicts are common especially in large and distributed software projects. There have been development to both make the conflicts less frequent by introducing better merge algorithms and to aid the user in resolving conflicts by better visualization and other means. However, one element lacking from the current conflict-resolving tools is the utilization of collective knowledge of project members, achievable through web-based collaboration. The person encountering the conflict may not have all the necessary information and understanding for resolving the conflict, in which case it would be beneficial to do the resolving collaboratively by all the parties who have been involved in causing the conflict or who otherwise have valuable information about the conflicted part of the project. In this paper, we present a process for real-time collaborative merging as well as a web-based tool supporting the process.
Selective DNA Delivery to Tumor Cells Using an Oligoarginine-LTVSPWY Peptide

DNA therapy for cancer requires efficient, selective and safe DNA delivery systems. Compared with other non-viral methods such as lipid or polymer-based DNA delivery vectors, peptide-based DNA delivery systems are biocompatible and biodegradable, which leads to lower immunogenicity and lower toxicity. Moreover, peptide vectors are easier to produce and their compositions easier to control because solid-phase peptide synthesis has been extensively developed. However, peptide-based systems for DNA delivery toward special tumor cells or tissues are still lacking. In this study, we constructed a non-viral 9rR-LTVSPWY peptide-based DNA delivery system and showed that it is able to efficiently and selectively transfect DNA into targeted tumor cells. This work presents a novel strategy for tumor cell-specific DNA delivery and a reference for designing more efficient DNA delivery systems targeted towards various types of cancer.
From Detail to Global View, an Impressionist Approach

This paper presents a new method for zooming out an image. As the Impressionism is one of the most complete painting technique, able to preserve notably details, light effects at a close or far range, we propose a method based on an impressionist approach. The input image is analyzed and described through impressionist characteristics that will be preserved when a zoom out will be realized. We created a set of characteristics of images and the corresponding algorithms to compute them. These characteristics are then used to build a set of zooming out algorithms. To validate the process, the zooms out have been applied to different types of images: photographs of paintings and other photographs. Results prove that this approach is more suitable than existing ones.
Cardiorespiratory Anomalies in Mice Lacking CB1 Cannabinoid Receptors

Cannabinoid type 1 (CB1) receptors are expressed in the nervous and cardiovascular systems. In mice, CB1 receptor deficiency protects from metabolic consequences of a high-fat diet (HFD), increases sympathetic activity to brown fat, and entails sleep anomalies. We investigated whether sleep-wake and diet-dependent cardiorespiratory control is altered in mice lacking CB1 receptors. CB1 receptor knock-out (KO) and intact wild-type (WT) mice were fed standard diet or a HFD for 3 months, and implanted with a telemetric arterial pressure transducer and electrodes for sleep scoring. Sleep state was assessed together with arterial pressure and heart rate (home cage), or breathing (whole-body plethysmograph). Increases in arterial pressure and heart rate on passing from the light (rest) to the dark (activity) period in the KO were significantly enhanced compared with the WT. These increases were unaffected by cardiac (β1) or vascular (α1) adrenergic blockade. The breathing rhythm of the KO during sleep was also more irregular than that of the WT. A HFD increased heart rate, impaired cardiac vagal modulation, and blunted the central autonomic cardiac control during sleep. A HFD also decreased cardiac baroreflex sensitivity in the KO but not in the WT. In conclusion, we performed the first systematic study of cardiovascular function in CB1 receptor deficient mice during spontaneous wake-sleep behavior, and demonstrated that CB1 receptor KO alters cardiorespiratory control particularly in the presence of a HFD. The CB1 receptor signaling may thus play a role in physiological cardiorespiratory regulation and protect from some adverse cardiovascular consequences of a HFD.
The Relationship between Elementary School Teachers’ Work Motivation and Well-Being: The Mediating Effects of Principal Leadership and Work Stress

This research intends to examine the mediating effects of elementary school teachers’ perception of principal leadership and work stress on the relationship between work motivation and well-being. For this purpose, the present study sampled 400 elementary school teachers from the Seoul metropolitan area in South Korea. Subsequently, the participants answered four scales to measure work motivation, perception of principal leadership, work stress, and well-being. The 324 data finally collected consist of 276 females and 48 males. The research results are as follows. First, four variables had significant correlations with each other, positively or negatively. Second, there was no significant mediating effect of principal leadership on work motivation and well-being. Third, teachers’ work stress had a partial mediating effect on the relationship between work motivation and well-being. Fourth, principal leadership and work stress had a sequentially partial mediating effect on work motivation and well-being. This paper discusses these findings and then suggests the directions for future research.
Sketch-Based Interface for animation for non-experts

We present a Sketch-Based Interface that allows non-expert users to create an animation from just pencil and paper. The interface works as a fast mockup tool for creating animations - turning the user's freehand 2D sketches into 3D animations. To facilitate animation construction in offline or computer-scarce scenarios, special emphasis is placed on paper-based instead of tablet-based sketches. The interface makes use of stroke shape, proximity, and orientation to give the user's drawings an animated interpretation. These Sketches use a 2D vocabulary of symbols, representing actors, actions and their relations. Custom symbols are defined by the user, and then associated with the relevant 3D assets within a database. The final composition of the sketches is passed into the system, employing image processing techniques for symbol recognition, and finally converting the user's intentions into a 3D animation.
A column generation approach to solve the crew re-scheduling problem

When tracks are out of service for maintenance during a certain period, trains cannot be operated on those tracks. This leads to a modified timetable, and results in infeasible rolling stock and crew schedules. Therefore, these schedules need to be repaired. The topic of this paper is the rescheduling of crew. In this paper, we define the Crew Re-Scheduling Problem (CRSP). Furthermore, we show that it can be formulated as a large-scale set covering problem. The problem is solved with a column generation based algorithm. The performance of the algorithm is tested on real-world instances of NS, the largest passenger railway operator in the Netherlands. Finally, we discuss some benefits of the proposed methodology for the company.
Fibroblasts, myofibroblasts, and wound contraction

clinical case reconstructed by Guido Majno (1975) from the Hippocratic records describes a wrestler who visits the iatreion (out-patient clinic) to be treated for a shoulder dislocation. With less invasive procedures no longer working to tighten the dislocation, the clinic adopts the drastic measure of inducing wound contraction by poking a hot needle through the skin of the armpit, and "in this way the cavity, into which the humerous is mostly displaced, is best scarred over and cut off" In Greek medicine circa 400 B.C.E. , familiarity with wound contraction after burn injury already was commonplace. Closure of cutaneous wounds involves three processes: epithelization, connective tissue deposition, and contraction. The contribution of each process varies according to the type of wound. In general, epithelization results in resurfacing of the wound; connective tissue deposition results in replacement of damaged dermis; and contraction brings the margins of open wounds together (Peacock, 1984; Clark, 1988; Mast, 1992). In mammals with loose skin (meaning loosely attached to the underlying tissue layer), wound contraction leads to wound closure with little scarring or loss of function. In humans, whose skin is more firmly attached to underlying tissues, the consequences of contraction are less beneficial, ranging from minimal cosmetic scar in some cases to loss of joint motion or major body deformation in others. Consequently, a distinction has been made between contraction as a normal process of wound closure, and contracture as the abnormal result of the contraction process where signifcant scarring or loss of function occurs (Hunt and Dunphy, 1979). The pathologic consequences of tissue contraction include a variety of conditions ranging from contracture of the fibrous capsule surrounding breast implants to constricture of hollow organs (e.g., the esophagus) after injury (Skalli and Gabbiani, 1988; Rudolph et al., 1992). In contemporary cell biology, research on wound contraction focuses on the wound fibroblast. Skin fibroblasts normally are sessile and quiescent, but shortly after cutaneous wounding, they become activated. Activated fibroblasts migrate to the fibronectin-fibrin wound interface, proliferate, and synthesize a new collagen-containing matrix called granulation tissue. Around the same time, wound contraction begins. Once the wound defect is replaced, the expanded fibroblast population stops dividing and regresses and extracellular matrix remodeling commences (Peacock, 1984; Clark, 1993). Despite the importance of wound contraction for wound
The su ( 2 | 3 ) Dynamic Spin Chain

The complete one-loop, planar dilatation operator of the N = 4 supercon-formal gauge theory was recently derived and shown to be integrable. Here, we present further compelling evidence for a generalisation of this integrable structure to higher orders of the coupling constant. For that we consider the su(2|3) subsector and investigate the restrictions imposed on the spin chain Hamiltonian by the symmetry algebra. This allows us to uniquely fix the energy shifts up to the three-loop level and thus prove the correctness of a conjecture in hep-th/0303060. A novel aspect of this spin chain model is that the higher-loop Hamiltonian, as for N = 4 SYM in general, does not preserve the number of spin sites. Yet this dynamic spin chain appears to be integrable.
GRADOOP: Scalable Graph Data Management and Analytics with Hadoop

Many Big Data applications in business and science require the management and analysis of huge amounts of graph data. Previous approaches for graph analytics such as graph databases and parallel graph processing systems (e.g., Pregel) either lack sufficient scalability or flexibility and expressiveness. We are therefore developing a new end-to-end approach for graph data management and analysis based on the Hadoop ecosystem, called Gradoop (Graph analytics on Hadoop). Gradoop is designed around the so-called Extended Property Graph Data Model (EPGM) supporting semantically rich, schema-free graph data within many distinct graphs. A set of high-level operators is provided for analyzing both single graphs and collections of graphs. Based on these operators, we propose a domain-specific language to define analytical workflows. The Gradoop graph store is currently utilizing HBase for distributed storage of graph data in Hadoop clusters. An initial version of Gradoop has been used to analyze graph data for business intelligence and social network analysis.
Hybrid method for 3D instrument reconstruction and tracking in laparoscopy surgery

3D instrument reconstruction and tracking are critical steps in minimally invasive surgery. Nowadays, some image-based methods have been proposed. Trying to minimize the damage to human body, those systems only used one camera as the major sensor to track and reconstruct the instrument and hence lost performance. For performance improvement, an inertial measurement unit (IMU) was newly integrated in our proposed system owing to two factors: first, the IMU could be installed in the instrument without extra body damage. Second, the IMU could provide direct motion information for tracking. However, the IMU measurements are far from perfect due to the gyro and acceleration biases. Thus, we proposed to compromise the information from a camera system and an IMU system to estimate the position, velocity and direction of the instrument. An Extended Kalman Filter was finally adopted to integrate information from different sources, compensate the biases of IMU, and track the instrument in a unified framework. The results of the experiment show the effectiveness of our method compared with image-based and IMU-based methods.
Comparison of CNTFET based 6T SRAM and MOSFET based 6T SRAM using Hspice.

The basic VLSI (Very Large Scale Integration) circuit element is Metal Oxide Semiconductor Field Effect Transistor (MOSFET). Moore’s law states that, design performance improves by reduction in gate length. The gate length reduction is also known as scaling. The continuous scaling of the circuit design will cause issues related to electrical performance of the chip. The device fabrication creates major problems when the geometry reaches to nanometer region. For the same purpose, the researchers have found Carbon Nano-Tubes (CNT) as the new worthy candidate. The design of CNT defines its properties, either metallic conductor or semiconductor. The transistor made from CNT is referred as CNT Field Effect Transistor (CNTFET). In this paper, we have drawn comparison of 6T SRAM between MOSFETs and CNTFETs. Section-1 gives brief introduction of MOSFETs and CNTFETs whereas section-2 describes the detailed properties of CNTFETs and section-3 gives details about CNTFET model. Section-4 describes the detailed description about 6T SRAM Section-5 gives simulation results of 6T SRAM. Section-6 summarizes the paper and shows future prospects of CNTFETs’ usage. Keywords— CNTFET, MOSFET, Chirality, Graphene, 6T SRAM
Rapid Reliability Assessment Using CADMP-II

One of the most time consuming activities in new product development is associated with reliability assessment and qualification. This is defined as a process to verify whether the anticipated reliability is indeed achieved under actual life cycle loads for some specified length of time. Reliability assessment and qualification is usually accomplished by testing under accelerated loads to achieve time compression. Typical qualification methods have been borrowed from the military, without knowledge of the rationale or assessment of the true benefits. In fact, prediction of field reliability from these tests has generally been quite poor. Nevertheless, the amount and length of qualification testing has increased over the years. This paper aims to provide a background to the qualification problem that much of industry is faced with today. Then provide an approach to reliability assessment, which provides a method for qualification requiring very little time and money, because the process is simulated.
A Bayesian Approach to Latent Class Modeling for Estimating the Prevalence of Schizophrenia Using Administrative Databases

Estimating the incidence and the prevalence of psychotic disorders in the province of Quebec has been the object of some interest in recent years as a contribution to the epidemiological study of the causes of psychotic disorders being carried out primarily in UK and Scandinavia. A number of studies have used administrative data from the Régie de l’assurance maladie du Québec (RAMQ) that includes nearly all Quebec citizens to obtain geographical and temporal prevalence estimates for the illness. However, there has been no investigation of the validity of RAMQ diagnoses for psychotic disorders, and without a measure of the sensitivity and the specificity of these diagnoses, it is impossible to be confident in the accuracy of the estimates obtained. This paper proposes the use of latent class analysis to ascertain the validity of a diagnosis of schizophrenia using RAMQ data.
