Merging Object-oriented Modelling with a 4 th Generation Environment

In the following we describe the modelli ng concepts of BOOM, a database-oriented development system we have built . We utili ze the term object-oriented 4thgeneration system to characterize our development because our intention was to merge concepts and techniques of object-oriented programming and modelli ng into a toolset containing components that are typically found in a 4th-generation system. The toolset supplied for the construction of information systems includes components for defining of structurally objectoriented data models, for generating of user interfaces, and arranging of application logic. Generic operations for manipulating user-defined objects are provided for every BOOM application. We describe the object model we implemented in our environment. We reflected on custom requirements and questions that arise during data modelli ng and how an object model should look like to easily meet these requirements. As such, we defined a structurally objectoriented model that is rich enough to cover all usual situations in modelli ng data-intensive applications. Our model includes the possibilit y to define an object’s structure, its constraints, and semantic relationships (inheritance, part-of, inverse relationships, .) and also offers other modelli ng constructs for defining application views and role types.
Mobile Augmented Reality System for Construction Site Visualization

This paper describes our mobile Augmented Reality (AR) system for construction site visualization and interaction. The mobile AR system can be operated either stand-alone, or as a client-server solution scaling down to mobile phones and tablets based on our lightweight tracking solution. The system is validated in field tests, covering architectural AR visualization with photorealistic rendering effects, up to construction time applications at a real building site.
Homeostatic regulation of photoreceptor cell integrity: significance of the potent mediator neuroprotectin D1 biosynthesized from docosahexaenoic acid: the Proctor Lecture.

Vision is sustained by a unique and beautiful relationship— that between photoreceptor cells and retinal pigment epithelial (RPE) cells. From the harmony of this cellular relationship emerges the life-long survival of the photoreceptor cell, despite the fact that the part of the eye where these cells interact is continuously exposed to potentially damaging factors. This relationship is one of the best examples of homeostasis in action as conceptualized for other cells and organs in 1932 by the physiologist Walter B. Cannon in The Wisdom of the Body (New York: W. W. Norton, 1932). Emerging questions to elucidate the intimacy of the successful intercellular relationship between photoreceptors and RPE include: How is integrity of the photoreceptor cell sustained? Does photoreceptor cell outer segment renewal modulate specific survival signaling to support the RPE cell during oxidative and nitrosylative challenges? The answers to these questions are needed to better our understanding of and to develop therapies for retinitis pigmentosa (RP), macular degenerations, and other retinal diseases.
Cosmetics Alter Biologically-Based Factors of Beauty: Evidence from Facial Contrast

The use of cosmetics by women seems to consistently increase their attractiveness. What factors of attractiveness do cosmetics alter to achieve this? Facial contrast is a known cue to sexual dimorphism and youth, and cosmetics exaggerate sexual dimorphisms in facial contrast. Here, we demonstrate that the luminance contrast pattern of the eyes and eyebrows is consistently sexually dimorphic across a large sample of faces, with females possessing lower brow contrasts than males, and greater eye contrast than males. Red-green and yellow-blue color contrasts were not found to differ consistently between the sexes. We also show that women use cosmetics not only to exaggerate sexual dimorphisms of brow and eye contrasts, but also to increase contrasts that decline with age. These findings refine the notion of facial contrast, and demonstrate how cosmetics can increase attractiveness by manipulating factors of beauty associated with facial contrast.
Choking under pressure: Illuminating the role of distraction and self-focus

ABSTRACT Two dominant explanations of choking under pressure – self-focus and distraction – have been enduringly presented as competing mechanisms of motor skill failure under performance stress. Dual-task experiments designed to simultaneously assess both mechanisms have often favoured self-focus, whereas qualitative research and examinations of gaze behaviour suggest that distraction plays a role. Though both mechanisms remain plausible, several reviews of the choking literature have side-stepped how autonomous motor skill failure would play out under a distraction-based model or a dual-mechanism model. In this discussion, we contend that persistent experimental focus on the brief moments of motor execution, without adequate consideration of diverse preparatory cognitive activities that also characterise sporting expertise, has delayed understanding of distraction’s involvement. With an expanded scope in mind, we critically review the evidence for both mechanisms and describe how distraction alone or distraction in combination with self-focus might derail an expert motor skill under pressure. Different suggestions are made for self-paced and externally paced sports given their different attentional challenges.
On Denial of Service Attacks in Software Defined Networks

Software defined networking greatly simplifies network management by decoupling control functions from the network data plane. However, such a decoupling also opens SDN to various denial of service attacks: an adversary can easily exhaust network resources by flooding short-lived spoofed flows. Toward this issue, we present a comprehensive study of DoS attacks in SDN, and propose multi-layer fair queueing (MLFQ), a simple but effective DoS mitigation method. MLFQ enforces fair sharing of an SDN controller's resources with multiple layers of queues, which can dynamically expand and aggregate according to controller load. Both testbed-based and emulation-based experiments demonstrate the effectiveness of MLFQ in mitigating DoS attacks targeted at SDN controllers.
Visualizing explicit and implicit relations of complex information spaces

In this work, we describe how EdgeMaps provide a new method for integrating the visualization of explicit and implicit data relations. Explicit relations are specific connections between entities already present in a given data set, while implicit relations are derived from multidimensional data based on similarity measures. Many data sets include both types of relations, which are often difficult to represent together in information visualizations. Node-link diagrams typically focus on explicit data connections while not incorporating implicit similarities between entities. Multidimensional scaling considers similarities between items; however, explicit links between nodes are not displayed. In contrast, EdgeMaps visualize both explicit and implicit relations by combining graph drawing and spatialization techniques. We have applied this technique to three case studies (philosophers, painters, and musicians) and explored how integrated visualizations of explicit and implicit relations reveal novel patterns and relationships.
Wondering why data are missing from query results?: ask conseil why-not

In analyzing and debugging data transformations, or more specifically relational queries, a subproblem is to understand why some data are not part of the query result. This problem has recently been addressed from different perspectives for various fragments of relational queries. The different perspectives yield different, yet complementary explanations of such missing-answers. This paper first aims at unifying the different approaches by defining a new type of explanation, called hybrid explanation, that encompasses the variety of previously defined types of explanations. This solution goes beyond simply forming the union of explanations produced by different algorithms and is shown to be able to explain a larger set of missing-answers. Second, we present Conseil, an algorithm to generate hybrid explanations. Conseil is also the first algorithm to handle non-monotonic queries. Experiments on efficiency and explanation quality show that Conseil is comparable to and even outperforms previous algorithms.
Alveolar antioxidant status in patients with acute respiratory distress syndrome

In the acutely inflamed lung, oxidant stress occurs within the alveolar compartment. Under these conditions, the regulation of low molecular weight antioxidants in the epithelial lining fluid is poorly understood. Therefore, antioxidant levels were measured in the bronchoalveolar lavage fluid (BALF) of patients with acute respiratory distress syndrome (ARDS; n=40) and in healthy volunteers (n=20). Reduced glutathione (GSH), oxidised glutathione (GSSG; enzymatic assay), retinol (vitamin A), α-tocopherol (vitamin E), ascorbic acid (vitamin C), uric acid (all by HPLC), plasmalogens (1-alkenyl-2-acyl phospholipids), polyunsaturated fatty acids (PUFA; both by gas–liquid chromatography), and F2-isoprostanes (ELISA) were quantified. All values are expressed as concentrations in cell-depleted BALF. GSSG (ARDS: 0.13±0.02 µM; control: 0.03±0.01 µM; mean±sem) and F2-isoprostanes (ARDS: 78±10 pM; control: 26±5 pM) were increased in ARDS, thus indicating oxidant stress. GSH levels in patients did not change significantly, whereas concentrations of vitamins A and C, vitamin E (ARDS: 77±15 nM; control: 26±3 nM) and uric acid (ARDS: 11.8±2.2 µM; control: 0.7±0.0 µM) were significantly elevated in ARDS. PUFA of total lipids, which may act as sacrificial antioxidants, increased by a factor of ∼3 in patients, but plasmalogens showed a significant decrease. In conclusion, low molecular weight antioxidants are elevated in the alveolar compartment of patients with acute respiratory distress syndrome. Further research is warranted to elucidate the molecular mechanisms underlying this finding.
Integrating Semantics within Compressed OLAP Views in the Hand-OLAP System (Extended Abstract)

In this paper, we provide further extensions of Hand-OLAP, a Java-based distributed system for enabling OLAP in mobile environments via intelligent data cube compression approaches. These extensions aim at integrating innovative semantics representation and management models within compressed OLAP views, in order to improve the data cube compression process itself, and to support an improved summarized, OLAP-like knowledge fruition from multidimensional data cubes throughout mobile devices. We complete our analytical contribution by means of an experimental evaluation of the novel semantics-based data cube compression approach on well-known benchmark data cubes, which definitely confirms to us the efficiency and the reliability of our proposed research.
Low-latency software defined network for high performance clouds

Multi-tenant clouds with resource virtualization offer elasticity of resources and elimination of initial cluster setup cost and time for applications. However, poor network performance, performance variation and noisy neighbors are some of the challenges for execution of high performance applications on public clouds. Utilizing these virtualized resources for scientific applications, which have complex communication patterns, require low latency communication mechanisms and rich set of communication constructs. To minimize the virtualization overhead, a novel approach for low latency network for HPC Clouds is proposed and implemented over a multi-technology software defined network. The efficiency of the proposed low-latency Software Defined Networking is analyzed and evaluated for high performance applications. The results of the experiments show that the latest Mellanox FDR InfiniBand interconnect and Mellanox OpenStack plugin gives the best performance for implementing VM-based high performance clouds with large message sizes.
Evaluer les inégalités sociales d'accès aux ressourcesIntérêt d'une approche fondée sur l'accessibilité

Alors que le lien entre manque d'acces aux ressources et processus d'exclusion sociale a ete mis en evidence depuis les annees 1990, la reponse des politiques publiques s'est essentiellement traduite par une amelioration des performances des systemes de transports. Ainsi la question des inegalites sociales d'acces est le plus souvent reduite a un probleme de mobilite. Or, la mobilite etant devenue une norme voire une injonction dans les societes urbaines contemporaines, les inegalites de mobilite sont particulierement difficiles a interpreter en termes d'inegalites sociales. Cet article cherche a mettre en evidence l'interet de la notion d'accessibilite, tant pour redefinir les problemes poses par les inegalites d'acces aux ressources que les solutions politiques permettant d'y repondre.
A Significant Root Leaf Wavelet Tree (SRLWT) Image Watermarking Technique Based on Tree Quantization

Digital watermarking techniques originally focused on copyright protection, but have been exploited in wide range of applications. There are several categories of watermarking schemes that are designed for different applications. Among them, robust watermarks are generally used for copyright protection and ownership identification because they are designed to withstand attacks such as common image processing operations. Recently to improve the compression of significance maps of wavelet coefficients, a new data structure called Wavelet Tree (WT) is introduced. The present paper extends the study on wavelet trees and developed new concept called Significant Root Leaf Wavelet Tree (SRLWT) to address the problem of 1) obtaining the best image quality for a given bit rate, and 2) to render the watermark more resistant to frequency based attacks, i.e., to achieve high robustness. This problem is important in many applications, particularly for progressive transmission, image browsing, multimedia applications and compatible transcoding in a digital hierarchy of multiple bit rates. It is also applicable to transmit over a noisy channel in the sense that the ordering of the bits in the order of importance leads naturally to prioritization for the purpose of layered protection schemes. Unlike other watermarking techniques which use a single casting energy, the proposed approach adopts adaptive casting energy in different resolutions. The experimental results indicate high robustness and image quality against various attacks when compared to several existing methods.
Conductor Loss Computation of Suspended Asymmetric Coplanar Waveguide

In this paper the conductor loss computation of suspended asymmetric coplanar wave guide (ACPW) is presented using quasi static spectral domain approach (SDA) method that incorporates the two layer conductor model of conductor and finite conductivity. The results of present method is compared with EM simulator-HFSS and CST in the frequency range 1-100 GHz. The average deviation in effective dielectric constant and conductor loss is about 1.27% and 11.0% respectively.
Energy-Constrained Paths for Optimization of Energy Consumption in Wireless Sensor Networks

A sensor spends a large part of its energy in transmitting its data and relay its neighbours' data. The overall lifetime of a wireless sensor network depends strongly on how a sensor selects its relaying neighbours and the data path to the destination. One critical problem is that if a sensor has to support too many neighbours, its energy is exhausted rapidly and may bring down the whole network. This paper suggests algorithms for assigning weights to links between neighbours taking into account the number of neighbours who rely on them to relay traffic to the destination. In order to do so, the paper also proposes an algorithm for constructing node connectivity based on sensors position within the broadcast range of another sensor, and a shortest energy-constrained path from a sensor to the destination.
Investigation of the Features About Steam Breakthrough in Heavy OilReservoirs During Steam Injection

With the further exploitation of heavy oil reservoirs, steam breakthrough blocks are seen in more and more areas and pose increasing damage. Based on the qualitative understanding of the formation mechanism of steam channeling, the concepts of steaming time and heat invading volume are introduced. After that, the geological models of steam injection of heavy oil reservoirs are established. We describe the sensitive factors affecting the steam channeling in a relatively accurate manner and mainly study the influence of several parameters on steaming time and heat invading volume. The results present that the possibility of steam channeling is higher and the time it takes is shorter when the permeability is greater, viscosity higher, depth shallower, steaming strength bigger and layer looser. Orthogonal design results show that the k-values of permeability on steaming time and heat invading volume are 7.43, 19.0 respectively, it has the most significant influence on two indicators.
Mouse cortical inhibitory neuron type that coexpresses somatostatin and calretinin

Mammalian cortex contains a diversity of inhibitory neuron types, each with distinct morphological, immunochemical, and/or physiological properties. In rat cortex, chemical markers distinguish at least four distinct and nonoverlapping neuron classes based on expression of parvalbumin (PV), somatostatin (SST), calretinin (CR), and cholecystokinin (CCK). It has generally been assumed that these classifications should also apply to other rodent species. In mouse cortex, however, we found significant colocalization of SST and CR in inhibitory neurons; about 30% of SST‐positive cells contained CR, and about 33% of CR‐positive cells contained SST across frontal, somatosensory (S1), and visual cortex (V1). The SST and CR colocalized cells were concentrated in layer 2/3. We further characterized morphological and physiological properties of the mouse cortical inhibitory neuron types that express SST by using “GIN” transgenic mice, in which GFP is expressed in a subset of SST inhibitory neurons (see Oliva et al. [ 2000 ] J Neurosci 20:3354–3368). Generally, both SST/CR+ cells and SST/CR− cells exhibited morphological features of Martinotti cells as described in rat cortex, and they also had similar accommodating spike‐firing patterns. However, they differed significantly in quantitative comparisons of morphology and spike shapes. SST/CR+ cells had more horizontally extended dendritic fields and more primary process than did SST/CR− cells; and SST/CR− cells had narrower action potential widths and faster afterhyperpolarization than did SST/CR+ cells. Thus, our data show an important species difference in the chemical distinction of inhibitory neuron subtypes, and indicate that colocalization of CR in SST cells correlates with different morphological and physiological features.

Effect of polymorphisms in the Slc11a1 coding region on resistance to brucellosis by macrophages in vitro and after challenge in two Bos breeds (Blanco Orejinegro and Zebu)

The resistance/susceptibility of selected cattle breeds to brucellosis was evaluated in an F1 population generated by crossing animals classified as resistant (R) and susceptible (S) (R x R, R x S, S x R, S x S) based on challenges in vitro and in vivo. The association between single nucleotide polymorphisms identified in the coding region of the Slc11a1 gene and resistance/susceptibility was estimated. The trait resistance or susceptibility to brucellosis, evaluated by a challenge in vitro, showed a high heritable component in terms of additive genetic variance (h2 = 0.54 ± 0.11). In addition, there was a significant association (p < 0.05) between the control of bacterial survival and two polymorphisms (a 3'UTR and SNP4 located in exon 10). The antibody response of animals classified as resistant to infection by Brucella abortus differed significantly (p < 0.05) from that of susceptible animals. However, there was no significant association between single nucleotide polymorphisms located in the Slc11a1 gene and the antibody response stimulated by a challenge in vivo.
ETH-Hardness for Signaling in Symmetric Zero-Sum Games

We prove that, assuming the exponential time hypothesis, finding an \epsilon-approximately optimal symmetric signaling scheme in a two-player zero-sum game requires quasi-polynomial time. This is tight by [CCDEHT'15] and resolves an open question of [Dughmi'14]. We also prove that finding a multiplicative approximation is NP-hard.
Genitofemoral neuralgia: adding to the burden of chronic vulvar pain

The vulva is a particularly common locus of chronic pain with neuropathic characteristics that occurs in women of any age, though most women with neuropathic type chronic vulvar pain will remain undiagnosed even following multiple physician visits. Here, we report on an exemplary case of a middle-aged woman who was referred to the Vulvovaginal Disease Clinic with debilitating vulvar burning and itching over the right labium majus that had been persisting for 2 years and was considered intractable. Careful history taking and clinical examination, followed by electrophysiological assessment through somatosensory evoked potentials was consistent with genitofemoral neuralgia, for which no obvious cause could be identified. Adequate pain relief was obtained with a serotonin–noradrenaline reuptake inhibitor and topical gabapentin cream. We briefly discuss the epidemiology, diagnosis, and treatment of genitofemoral neuralgia and provide a series of clues to guide clinicians in obtaining a presumptive diagnosis of specific neuropathic pain syndromes that may underlie chronic vulvar pain. We further aim to draw attention to the tremendous burden of chronic, unrecognized vulvar pain.
How Was Your Day?

We describe a 'How was your day? ' (HWYD) Companion whose purpose is to establish a comforting and supportive relationship with a user via a conversation on a variety of work-related topics. The system has several fairly novel features aimed at increasing the naturalness of the interaction: a rapid 'short loop' response primed by the results of acoustic emotion analysis, and an 'interruption manager', enabling the user to interrupt lengthy or apparently inappropriate system responses, prompting a replanning of behaviour on the part of the system. The 'long loop' also takes into account the emotional state of the user, but using more conventional dialogue management and planning techniques. We describe the architecture and components of the implemented prototype HWYD system.
Exploiting Visual Perception for Sampling-Based Approximation on Aggregate Queries

Efficient sampling algorithms have been developed for approximating answers to aggregate queries on large data sets. In some formulations of the problem, concentration inequalities (such as Hoeffding’s inequality) are used to estimate the confidence interval for an approximated aggregated value. Samples are usually chosen until the confidence interval is arbitrarily small enough regardless of how the approximated query answers will be used (for example, in interactive visualizations). In this report, we show how to exploit visualization-specific properties to reduce the sampling complexity of a sampling-based approximate query processing algorithm while preserving certain visualization guarantees (the visual property of relative ordering) with a very high probability.
