Multifactor Authentication Protocol in a Mobile Environment

The implementation of services that process confidential data in a mobile environment requires an adequate level of security with the strictest possible mechanisms of information protection. The dominance of mobile devices as client applications of distributed systems has led to the development of new techniques that combine traditional methods of protection with protocols leveraging the potential of numerous interfaces available from a smartphone. For this reason, an upward trend in the use of biometrics-based methods and dynamically generated OTP secrets can be observed. Mobile devices are increasingly used in complex business processes that require strong user authentication methods, which, according to the European Commission (Regulation), must use at least two authentication factors belonging to different categories. Therefore, on the basis of the analysis of the solutions presented so far, a distributed protocol has been proposed. It enables user authentication using three authentication factors: possession, knowledge, and inherence. The described authentication scheme refers to the possibility of carrying out the process in the mobile environment of the Android platform with guaranteed authentication support.
Robust Linear-Complexity Approach to Full SLAM Problems: Stochastic Variational Bayes Inference

The simultaneous localization and mapping (SLAM) problem involves using the measurements of sensors to construct an environmental map, while simultaneously recovering the vehicle trajectory within this map. There are broadly two strategies for SLAM: on-line and off-line. In this paper, we focus on the off-line SLAM (a.k.a. full SLAM) problem and propose a variational Bayes inference algorithm to address it. Specifically, the intractable posterior distribution of the vehicle poses given the measurements is approximated by a tractable variational distribution, resulting in estimates of the vehicle poses as well as their uncertainties. In contrast with the existing off- line methods, the inverse variances of the additive noise are updated along with the posterior distribution instead of being fixed, thus, the proposed method is robust to unknown noises. Furthermore, the computational complexity of the proposed method is only linear in the number of frames and the computational bottleneck of the algorithm can be easily parallelized to achieve further acceleration. Numerical results show that the proposed method is insensitive to the selection of the noise parameters. More importantly, it is superior in efficiency to the state-of-the-art method, especially for large- scale SLAM problems.

Relay Selection Strategies for Physical-Layer Security in D2D-Assisted Cellular Networks

Two sequential relay selection strategies are investigated for a cooperative relay-assisted device-to-device (D2D) communication underlaying cellular network over mixed fading channels. The relay selection schemes aim to improve the D2D communication performance and the wireless physical layer security of the cellular network. In this paper, the study is conducted analytically by obtaining an expression for the secrecy outage probability (SOP) of the cellular network. Moreover, in an effort to assess the usefulness of the cooperation between the two networks, an expression for the mutual outage probability (MOP)â€"which represents the true outage probability across both the D2D and cellular networksâ€"is derived. Also, an asymptotic analysis of the MOP in the high signal-to-noise ratio regime is obtained and the diversity order is evaluated. Monte-Carlo simulations are provided to validate the accuracy of our proposed analytical framework.
Spotlight on Off-Screen Points of Interest in Handheld Augmented Reality: Halo-based techniques

Navigating Augmented Reality (AR) environments with a handheld device often requires users to access digital contents (i.e. Points of Interests - POIs) associated with physical objects outside the field of view of the device's camera. Halo3D is a technique that displays the location of off-screen POIs as halos (arcs) along the edges of the screen. Halo3D reduces clutter by aggregating POIs but has not been evaluated. The results of a first experiment show that an enhanced version of Halo3D was 18% faster than the focus+context technique AroundPlot* for pointing at a POI, and perceived as 34% less intrusive than the arrow-based technique Arrow2D. The results of a second experiment in more realistic settings reveal that two variants of Halo3D that show the spatial distribution of POIs in clusters (1) enable an effective understanding of the off-screen environment and (2) require less effort than AroundPlot* to find POIs in the environment.
POSTER: An Optimized Predication Execution for SIMD Extensions

Vector processing is a widely used technique to improve performance and energy efficiency in modern processors. Most of them rely on predication to support divergence control. However, performance and energy consumption in predicated instructions are usually independent on the number of true values in a mask. This means that the efficiency of the system becomes sub-optimal as vector length increases. In this work we propose the Optimized Predication Execution (OPE) technique. OPE delays the execution of sparse masked vector instructions sharing the same PC, extracts their active elements and creates a new dense instruction with a higher mask density. After executing such dense instruction, results are restored to the original sparse instructions. Our approach improves performance by up to 25% and reduces dynamic energy consumption by up to 43% on real applications with predication.

Two generations of exsolution lamellae in pyroxene from Asuka 09545: Clues to the thermal evolution of silicates in mesosiderite

Abstract Mesosiderite meteorites consist of a mixture of crustal basaltic or gabbroic material and metal. Their formation process is still debated due to their unexpected combination of crust and core materials, possibly derived from the same planetesimal parent body, and lacking an intervening mantle component. Mesosiderites have experienced an extremely slow cooling rate from ca. 550 °C, as recorded in the metal (0.25–0.5 °C/Ma). Here we present a detailed investigation of exsolution features in pyroxene from the Antarctic mesosiderite Asuka (A) 09545. Geothermobarometry calculations, lattice parameters, lamellae orientation, and the presence of clinoenstatite as the host were used in an attempt to constrain the evolution of pyroxene from 1150 to 570 °C and the formation of two generations of exsolution lamellae. After pigeonite crystallization at ca. 1150 °C, the first exsolution process generated the thick augite lamellae along (100) in the temperature interval 1000–900 °C. By further cooling, a second order of exsolution lamellae formed within augite along (001), consisting of monoclinic low-Ca pyroxene, equilibrated in the temperature range 900–800 °C. The last process, occurring in the 600–500 °C temperature range, was likely the inversion of high to low pigeonite in the host crystal, lacking evidence for nucleation of orthopyroxene. The formation of two generations of exsolution lamellae, as well as of likely metastable pigeonite, suggest non-equilibrium conditions. Cooling was sufficiently slow to allow the formation of the lamellae, their preservation, and the transition from high to low pigeonite. In addition, the preservation of such fine-grained lamellae limits long-lasting, impact reheating to a peak temperature lower than 570 °C. These features, including the presence of monoclinic low-Ca pyroxene as the host, are reported in only a few mesosiderites. This suggests a possibly different origin and thermal history from most mesosiderites and that the crystallography (i.e., space group) of low-Ca pyroxene could be used as parameter to distinguish mesosiderite populations based on their cooling history.
‘Cell cycle’ and ‘cell death’- related genes are differentially expressed during long – term in vitro real-time cultivation of porcine oviductal epithelial cells

Abstract Alterations in cells depend on their genetic material, its activation and translation of the products. The genes responsible for the cell cycle processes and apoptosis of porcine oviductal cells have been presented in our study. The processes occurring in the reproductive system of females are extremely complex and require in-depth knowledge. Thanks to in vitro studies on the fallopian tube epithelium cells, we can get closer to understanding the biochemical and morphological changes occurring in mammalian organisms. Our research was conducted on fallopian tubes obtained from commercially bred pigs and its aim was to assess the expression profile of genes responsible for the most important processes of cellular life. Cell cultures were carried out for 30 days, with the obtained cells subjected to molecular analysis. We have shown significant regulation of “cell death” and “cell cycle” genes, some of which are related to the reproductive system. The alterations in transcriptomic profile and mutual relations between the genes were analyzed and related to the literature findings. The knowledge gained could help in identifying new potential markers of the in vitro occurrence of processes described by the ontology groups of interest.

The angiotensinogen gene polymorphism, lifestyle factors, associated diseases and gastric areas of inflammatory and preneoplastic lesions in a Romanian sample of patients

Abstract The aim of our study was to evaluate the association between variant genotype of angiotensinogen (AGT) c. -58A>C, lifestyle factors and clinical factors and corporeal extension of gastric inflammatory and preneoplastic lesions. Methods: Our study included 209 subjects who underwent a complete set of gastric biopsies, followed by genotyping. They were included to study inflammatory gastric changes and preneoplastic lesions and were grouped according to the localization of changes. Results: No significant statistical associations were noticed between AGT c. -58A>C genotypes and the corporeal extension of the inflammation or preneoplastic injury groups. Extending preneoplastic lesions to the gastric body was associated with smoking habits (p=0.01) and additionally, there was a significant association between nicotine consumption and the body extension of preneoplastic lesions (p=0.01). The use of acenocoumarol was frequently associated with the progression of histological lesions to preneoplastic lesions (p=0.01). Compared with the wild-type AA genotype, the combined genotypes AA+CC of AGT c. -58A>C were significantly associated with the progression of inflammatory gastric lesions’ according to the regular ingested doses of nonsteroidal anti-inflammatory drugs (NSAIDs). Conclusion: The AGT c. -58A>C polymorphism is not associated with extension of the gastric lesions. In accordance with nicotine and alcohol consumption, the acenocoumarol co-treatment and multiple cardiac pathologies are associated with the corporeal progression of these injuries. The age below 70 years and NSAIDs treatment for the patients with heterozygous AC genotype and variant homozygous CC genotype for the mentioned SNP have been associated with the corporeal extension of gastric inflammation.
Quantification of Germination Response of Millet (Panicum miliaceum L.) Seeds to Water Potential and Priming using Hydrotime Model

Abstract Seed germination is a complex biological process that is influenced by different environmental physical factors including temperature, water potential, salinity, pH and light, as well as intrinsic genetic factors. In such environments, the water needed for germination is available for only a short time, and consequently, successful crop establishment depends not only on rapid and uniform germination of the seedlot, but also on its ability to germinate under low water availability. All of these attributes can be analyzed through the hydrotime model (HT). Millet (Panicum miliaceum L.) is cultivated in arid and semi-arid regions of Iran. Therefore, in this study, using the hydrotime modeling approach, germination response of millet to priming (water and gibberellin 50 ppm at 15°C for 24 h) and water potential (0, -0.3, -0.6, -0.9, and -1.2 Mpa) was studied. Hydrotime (HT) model were fitted to cumulative germination of seeds and recorded in germination tests carried out at different water potentials (0, -0.3, -0.6, -0.9 and -1.2 MPa) and priming treatments (control, hydropriming and hormone priming). Results showed that, germination of millet decreased significantly with reduction of osmotic potential. Results indicated that the hydro-time constant (θH) for control, hydro-priming and hormone priming were 0.89, 0.79 and 0.67 MPa d, the water potential (Ψb(50)) for control, hydropriming and hormone priming were -0.89, -0.94 and -1.11 MPa, respectively. Results indicated that the use of hydrotime model in germination prediction could be useful to provide more accurate estimates for the timing of sowing and management of millet.

Indication specific treatment modalities for spinal disorders a comprehensive biomechanical investigation

The cause and best treatment option for mechanical low back pain due to disc degeneration remains unsolved, despite ‘spinal fusion’ being the gold standard of surgical treatment, post conservative care, for a very long time. However, the potential drawbacks of spinal fusion and the ongoing evolution in the understanding of normal and symptomatic spine biomechanics, biology and mechanobiology in conjunction with the advancements in material sciences, and tissue engineering has led to a change in the clinical perspective towards treatment methodologies for spinal disorders. Clinically, a gradual shift in philosophy is being observed from a ‘one size fits all’, i.e. spinal fusion for all patients with symptomatic low back pain to a ‘customized approach’, i.e. patient and indication specific treatment modalities for spine care. This philosophy has laid the ground for concepts of „motion preservation’ and ‘dynamic stabilization’, the former being an established treatment modality in orthopedics for a long time. The aim of the current study is to perform a comprehensive scientific investigation to understand, evaluate and establish the in vitro biomechanical characteristics and performance of indication specific treatment modalities incorporating the concept of Posterolateral Disc Arthroplasty and Posterior Dynamic Stabilization for the treatment of symptomatic mechanical back pain. The results of this comprehensive study may help the clinicians to make an informed decision while selecting and designing a treating modality for their patients. To this end, the current thesis was undertaken to study the biomechanics of indication specific treatment modalities like motion preservation and dynamic stabilization with a goal to guide clinical and product development decision making.
Comparative genetic stock structure in three species of commercially exploited Indo-Malay Carangidae (Teleosteii, Perciformes).

We examine genetic structuring in three commercially important species of the teleost family Carangidae from Malaysian waters: yellowtail scad Atule mate, bigeye scad Selar crumenophthalmus and yellowstripe scad Selaroides leptolepis, from the Indo-Malay Archipelago. In view of their distribution across contrasting habitats, we tested the hypothesis that pelagic species display less genetic divergence compared with demersal species, due to their potential to undertake long-distance migrations in oceanic waters. To evaluate population genetic structure, we sequenced two mitochondrial (mt)DNA [650bp of cytochrome oxidase I (coI), 450bp of control region (CR)] and one nuclear gene (910bp of rag1) in each species. One hundred and eighty samples from four geographical regions within the Indo-Malay Archipelago including a population of yellowtail from Kuwait were examined. Findings revealed that the extent of genetic structuring among populations in the semi-pelagic and pelagic, yellowtail and bigeye were lower than demersal yellowstripe, consistent with the hypothesis that pelagic species display less genetic divergence compared with demersal species. The yellowtail phylogeny identified three distinct clades with bootstrap values of 86-99% in mtDNA and 63-67% in rag1. However, in bigeye, three clades were also observed from mtDNA data while only one clade was identified in rag1 dataset. In yellowstripe, the mtDNA tree was split into three closely related clades and two clades in rag1 tree with bootstraps value of 73-99% and 56% respectively. However, no geographic structure appears in both mtDNA and rag1 datasets. Hierarchical molecular variance analysis (AMOVA), pair wise FST comparisons and the nearest-neighbour statistic (Snn ) showed significant genetic differences among Kuwait and Indo-Malay yellowtail. Within the Indo-Malay Archipelago itself, two distinct mitochondrial lineages were detected in yellowtail suggesting potential cryptic species. Findings suggests varying degrees of genetic structuring, key information relevant to management of exploited stocks, though more rapidly evolving genetic markers should be used in future to better delimit the nature and dynamics of putative stock boundaries.

The Perception of Interaction on the University Examination Timetabling Problem

In real-world perspective, educational institutions have come across a mixture of formulation for the examination timetabling problem and still semiautomated scheduling systems are in practice. In this paper, we look into the knowledge abstractions techniques to reduce the complexity of problem solving for university examination timetabling problem. The methods consists of recapitulate, visual analysis heuristic (VAH), and specification. The recapitulation groups the successive components, thus reducing the size of the problem. The clustering heuristics, partitioning the problem into easy and difficult components interacting through abstracted pools. The hierarchy of pools allows the user to intervene in conflict resolution at the most appropriate level of abstraction. The specification simplify the decouple components to aid the user in assessing the stiffness of the problem. We propose an algorithm that interleaves these processes. The combinations of these three techniques are evaluated with the real-world examination timetabling room allocation problem scenario. The merits of our approach are minimizing the need for backtracking, provides interactive visual models framework to understand the conflict resolution and offering a comprehensive direction to feasible solution.
