Markov property of correlated random networks and its application to the analysis of the internet topologies

We propose a framework for modeling higher-order (beyond two point) degree correlation among nodes, depending on their mutual connectivity. Our focus is on the introduction of the Markov property to find maximally unbiased networks under the constraint of a prescribed two-point degree correlation. The topological features of the Markovian networks -- networks satisfying the Markov property -- are fully characterized solely by the two-point degree correlation. We theoretically investigate the topological characteristics of Markovian networks and derive the analytical formulas for their graph theoretical metrics. We present a comparative analysis of AS- and router-level topologies in terms of whether they are Markovian or not. The results of the analysis show that the studied AS- and router-level topologies are not Markovian. This finding indicates that it is rather difficult to capture the topological characteristics of the Internet either at AS- or at router-level solely by the input of the two-point degree correlation.
Comparison of Photon Counting Devices Using Antibiotics and Heavy Metal Biosensors

Bioluminescence has been of great interest for the past few decades. There have been plenty of biotechnological methods to detect, estimate, view and establish the bioluminescence obtained from variety of organisms. Due to the advancements in genetic engineering technologies, increasing number of instruments has been manufactured for the detection and counting of bioluminescence. However, very few studies have been reported comparing the efficiency and working of different photon counting instruments available today. Henceforth, special effort has been taken to study and compare the photon counting devices in this thesis. The aim of the thesis is to compare three different photon counting devices available at the laboratory of environmental engineering and biotechnology; namely Chameleon Multilabel plate reader from Hidex Oy, Victor Wallac from Perkin Elmer life sciences and IVIS Lumina Xenogen from Caliper Life Sciences. The efficiency of these three devices were compared by using two different bacterial strains, one is bioluminescent whole-cell biosensor strain, Escherichia coli DPD2794 and the other being an arsenic biosensor strain Escherichia coli XL-1(parsRluxCDABE). These Genetically engineered bacterial strains have been grown under laboratory conditions and comparative luminescence was done by bioluminescence measurement methods and agar diffusion method (bio-photonic imaging station). Inducible ciprofloxacin with different concentrations were used for Escherichia coli DPD2794 and arsenite NaAsO2 (III) and arsenate Na2HAsO4 (V) were used as a biosensor for detecting the amount of bioluminescence emitted from respective bacterial species. On comparing the efficiency of bioluminescence detected by three different photon counting devices, Chameleon was found to provide most sensitive and IVIS the lowest. However all the approaches is useful depending upon the application employed.

Quantum group GLq(2) and quantum Laplace operator via semi-infinite cohomology

We construct the quantum group $GL_q(2)$ as the semi-infinite cohomology of the tensor product of two braided vertex operator algebras based on the algebra $W_2$ with complementary central charges $c+\bar{c}=28$. The conformal field theory version of the Laplace operator on the quantum group is also obtained.
The Effect of Art-Making on Emotion by Unilateral Hemispheric Activation

This research study investigates whether or not the motor action of art-making through the process of art therapy influences brain activity in a way that affects emotional state. The participants were 133 adults from introductory psychology classes at the College at Brockport, State University of New York. Participants drew on a piece of paper located either to the right or left of the center of the table for five minutes while wearing goggles that directed their vision in the same direction. This was preceded and followed by a measure of emotional state. Findings suggest that side of drawing has a greater impact on the happiness of non-depressed participants and the sadness of depressed participants.
Value Chains and Nutrition: A Framework to Support the Identification, Design, and Evaluation of Interventions

In this paper we explore how a value chain framework can inform the design of interventions for achieving improved nutrition. Conceptually, there are three main channels for value chains to improve nutrition: (1) through increased consumption of nutritious foods (a demand side pathway); or (2) through increased incomes from value chain transactions (a supply side pathway) or (3) through increased nutrition value-addition in the chain transactions. These three pathways are interlinked and involve complex dynamics that are not straightforward to understand.
ole of intra-hippocampal orexin 1 and orexin 2 receptors in onditioned place preference induced by chemical stimulation of the ateral hypothalamus

Evidence from animal models suggests a role for orexinergic system in reward processing and drug addiction. The lateral hypothalamus (LH) orexin neurons send projections to the dorsal hippocampus (CA1 region) which plays a pivotal role in reward processes. Moreover, it has been shown that orexin containing terminals and orexin receptors are distributed in the hippocampal formation. In this study, we assessed the role of orexin 1 (OX1r) and orexin2 (OX2r) receptors in the CA1 on the development of LH stimulationinduced conditioned place preference (CPP). Animals weighing 230–280 g were unilaterally implanted by two separate cannulae into the LH and CA1. The CPP paradigm was done; SB334867 and TCSOX229, as selective OX1r and OX2r antagonists (1, 3, 10 and 30 nM/0.5 l DMSO) administrated into the CA1 prior to intra-LH carbachol microinjection (250 nM; the most effective dose) during the 3-days conditioning phase, respectively. Conditioning scores and locomotor activities were recorded by Ethovision software on the test day. The results showed that the administration of OX1r and OX2r antagonists into the CA1 onditioned place preference attenuated the development of CPP induced by chemical stimulation of the LH. However, this decrease in OX1r antagonist treated groups was more significant than that in OX2r antagonist treated animals. Our findings suggest that OX1 and OX2 receptors in the CA1 region of the hippocampus were involved in the development of CPP induced by chemical stimulation of the LH and the efficiency of OX1 receptors in this phenomenon was more considerable than OX2 receptors in rats.

Molecular characterization of virulence and resistance features in Staphylococcus aureus clinical strains isolated from cutaneous lesions in patients with drug adverse reactions

Patients treated with epidermal growth factor inhibitors often experience cutaneous adverse reactions that could be complicated by infections driven by specific pathogens such as the community emergent methicillin resistant Staphylococcus aureus. This study was conducted on a total of 42 S. aureus clinical strains isolated in 2016 from acneiform reactions pustule and periungual lesions in patients with cutaneous drug adverse reactions. Multiplex PCR was performed on genomic DNA from isolates in order to identify the SCCmec central elements and the virulence genes: bbp (bone bound sialoprotein), ebpS (elastin-binding protein), fnbB, fnbA (fibronectin-binding proteins), fib, clfA, clfB (clumping factors A and B), cna (collagen-binding protein), luk-PV (Panton-Valentine leukocidin), hlg (gamma-haemolysin), tst (toxic shock syndrome toxin). The obtained results confirmed the increased virulence potential and the high prevalence of SSCmec type VIII, followed by type IV and II in cutaneous isolates from patients with dermatologic toxic effects.
Do previous survey experience and participating due to an incentive affect response quality? Evidence from the CRONOS panel

As ever more surveys are conducted, recruited respondents are more likely to already have previous survey experience. Furthermore, it has become more difficult to convince individuals to participate in surveys, and thus, incentives are increasingly used. Both previous survey experience and participation in surveys due to incentives have been discussed in terms of their links with response quality. This study aims to assess whether previous web survey experience and survey participation due to incentives are linked with three indicators of response quality: item non‐response, primacy effect and non‐differentiation. Analysing data of the probability‐based CROss‐National Online Survey panel covering Estonia, Slovenia and Great Britain, we found that previous web survey experience is not associated with item non‐response and the occurrence of a primacy effect but is associated with non‐differentiation. Participating due to the incentive is not associated with any of the three response quality indicators assessed. Hence, overall, we find little evidence that response quality is linked with either previous web survey experience or participating due to the incentive.
User Interaction Modelling for Adaptive Human Computer Interaction

The advancement of technology and computer systems requires continuous enhancement by means of the interaction between users and computers. Subsequently, the availability of unobtrusive visualised input modalities, such as eye trackers and RGB cameras has enabled the viable detection of users’ emotions and cognitive states. However, how to utilise such pervasive input modalities to enable a computer to actively interact with a user based on their current emotional and cognitive states is a challenging problem. This paper presents a research study that is currently taking place at Ulster University, which seeks to investigate creating a user model that facilitates future creation of Adaptive Human Computer Interaction. In other words, this research project focuses on exploiting visual-based input modalities to perceive and infer a user’s emotional and cognitive states in order to predicate adaptation of the graphical user interface or indeed the user interaction.
SPANISH IN A REGULAR CLASSROOM SETTING

When listeners are presented with phones that are not used in their own language, they typically perceive sounds in a way that is not as good as a native speaker of the language from which the phones were selected (García-Perez, 2003; Bradlow and Pisoni, 1997; Munro, Flege, and Mackay, 1996; Rochet, 1995; Munro, 1993; Werker, 1989). From a second language teaching (SLT) point of view, this issue can have both practical and theoretical implications. In practice, the teacher can foresee the difficulties the students may experience distinguishing certain phonetic contrasts in the second language. Theoretically, the teacher could look for the conditions that facilitate the development of the second language student’s ability to differentiate the new phonetic categories. The present study focuses on the theoretical implications of this phenomenon in the context of training Spanish students to identify English pairs of vowels /ι/-/Ι/, /υ/-/Υ/, and /℘/-/Α/. Categorical perception is a phenomenon in which labeling limits discrimination. This allows listeners to segment the words they hear according to the phonemic categories of their language and ignore unessential variations within a category. However, studies have shown that infants do not need to learn about phonemic categories to be able to group speech stimuli; they can do this soon after birth (Eimas, 1975). Moreover, studies have shown that infants are able to distinguish many, but not
Informativity and the actuation of lenition

What causes Indonesian to lenite word-final /k/, American English to lenite word-final /t/, and Spanish to lenite word-final /s/? This article shows that all three observed lenition patterns can be motivated using a single principle: languages preferentially lenite segments that provide relatively low informativity compared to the amount of informativity those segments carry in other languages. In a comparison of a diverse sample of seven languages from the LDC CALLHOME and CALLFRIEND corpora, Indonesian /k/, American English /t/, and Spanish /s/ are found to have the lowest informativity, predicting that they would be more likely to be affected by sound change processes. In a subsequent regression-based corpus study, low informativity predicted the propensity of word-final lenition of all obstruents in American English after phonetic and phonological factors were controlled for. This article therefore provides a partial solution to the famous actuation problem (Weinreich et al. 1968) with respect to the actuation of lenition processes.
Faculty Use of Subscribed Journals in a Spanish Library Consortium: Downloads and Citations in the Field of Psychology

Abstract We present a case study to analyze the bibliographic references used in the scientific production on psychology in Scopus of the four universities that make up a library consortium in Spain and compare this with downloads of journals included in the Springer, Elsevier, Wiley, and Emerald big deals subscribed to by this consortium. A majority use journals scribed to through the big deals is observed, at the level of both downloads and citations, although with a weak correlation between the two variables.
IN SITU CHARACTERIZATION OF ALKALI ANTIMONIDE PHOTOCATHODES

Alkali antimonide photocathodes are a prime candidate for use in high-brightness photoinjectors of free electron lasers and 4th generation light sources. These materials have complex growth kinetics - many methods exist for forming the compounds, each photocathode having different grain size, roughness, and crystalline texture. These parameters impact the performance of the cathodes, including quantum efficiency (QE), intrinsic emittance and lifetime. In situ analysis of the growth of these materials has allowed investigation of correlations between the growth parameters and the resulting cathode performance. This work explores the relationship between the crystallinity of the initial antimony film and the roughness of the final cathode. Two growth methods are compared ‐ a “traditional” recipe which uses a crystalline initial antimony film and a “yo-yo” process which builds the cathode through an iterative process using sub-crystalline antimony layers. The traditional method provides exemplary QE (7.5% @ 532 nm), but an exceptionally rough surface. The “yo-yo” produces a somewhat lower final QE (4.9% @ 532 nm) but a much smoother surface, as observed by grazing incidence small angle x-ray scattering (GISAXS).
Representation learning in the artificial and biological neural networks underlying sensorimotor integration

The integration of deep learning and theories of reinforcement learning (RL) is a promising avenue to explore novel hypotheses on reward-based learning and decision-making in humans and other animals. Here, we trained deep RL agents and mice in the same sensorimotor task with high-dimensional state and action space and studied representation learning in their respective neural networks. Evaluation of thousands of neural network models with extensive hyperparameter search revealed that learning-dependent enrichment of state-value and policy representations of the task-performance-optimized deep RL agent closely resembled neural activity of the posterior parietal cortex (PPC). These representations were critical for the task performance in both systems. PPC neurons also exhibited representations of the internally defined subgoal, a feature of deep RL algorithms postulated to improve sample efficiency. Such striking resemblance between the artificial and biological networks and their functional convergence in sensorimotor integration offers new opportunities to better understand respective intelligent systems.
Stadler Applications of the Covariant Spectator Theory

In this talk I provide a short overview of applications of the so-called Covariant Spectator Theory to twoand three-nucleon systems. It is a quasi-potential f ormalism based on relativistic quantum field theory, and can be derived from a reorganization of the complete Beth e-Salpeter series. In this framework, we constructed two one-boson-exchange models, called WJC-1 and W JC-2, for the neutron-proton interaction that fit the 2007 world data base, containing several thousands of neutron-proton scattering data below 350 MeV, with a χ/Ndata close to 1. The close fit to the observables implies that the ph ase shifts derived from these models can be interpreted as new phase-shift analyses, whic h can be used also in nonrelativistic frameworks. Both models have a considerably smaller number of adjustabl e parameters than are present in realistic nonrelativistic potentials, which shows that the inclusion of rel ativity actually helps to achieve a realistic description of the interaction between nucleons. This became also evide nt n calculations of the three-nucleon bound state, where the correct binding energy is obtained without additional irreducible three-body forces which are needed in nonrelativistic calculations. In addition, calc ulations of the electromagnetic form factors of helium3 and of the triton in complete impulse approximation also gi ve very reasonable results, demonstrating the Covariant Spectator Theory’s ability to describe the struc ture of the three-nucleon bound states realistically.
Optimizing MFCC Settings for Low-Complexity VAD Systems - a Case Study

Recent advances in machine learning strategies for speech classification require increasingly complex classifiers and large numbers of features. For practical application in lowresource systems, such methods use prohibitively large numbers of operations. A better approach involves reducing the features to the fewest, most salient ones, while simplifying the classifier structure to a minimum. The mel-frequency cepstral coefficients (MFCCs) are often used in speechrelated classification tasks, which suggests the compressed information therein is highly informative. They are computed by warping the spectral energy to a mel scale, followed by a logarithm and a discrete cosine transformation. To better understand the properties governing such features, we examine different MFCC configurations using a simple neural network classifier for a low-complexity voice activity detector. In particular, we investigate the optimal number of MFCCs, the extent of the required temporal information and the best compression rate for different analysis settings, with varying frequency resolutions.
Comprehensive analysis of lung adenocarcinoma patients with gefitinib as first-line , second-line and third-line treatment

Objective: To evaluate the prognostic factors of overall survival (OS) and progression-free survival (PFS) of lung adenocarcinoma patients received gefitinib as first-line, second-line and third-line treatment. Methods: Total of 43 lung adenocarcinoma patients hospitalized in Taian City Central Hospital of Shandong province from May 2006 to August 2012 were incorporated into our retrospective study according to the inclusion and exclusion criteria. The mean follow-up was 20.4±9.1 months. The information of patients was recorded as gender, age, smoking, complications, organ metastasis (liver, bone, brain and adrenal gland), tumor stage, EGFR (epidermal growth factor receptor) mutation, adverse effect, gefitinib-response, gefitinib therapeutic regimen. Chi-square test and t-test were performed to analyze collection data, Log-rank was performed to univariate analysis of OS and PFS among groups. Results: The median overall survival of 43 patients was 19 months (95% confidence interval: 16-22 months). Univariate analysis displayed that tumor stage, EGFR mutation and organ metastasis were prognostic factors of OS and PFS (P<0.05); gender, age, smoking, complications, organ metastasis, tumor stage, EGFR mutation, adverse effect, gefitinib therapeutic regimen were not prognostic factors of OS and PFS among groups. Conclusion: Tumor stage, EGFR mutation and organ metastasis were prognostic factors of OS and PFS of lung adenocarcinoma patients.
Mechanisms of calcium disposal from osteoclastic resorption

One of the most remarkable but neglected aspects of osteoclast function is its unique adaptation that allows the cell to function despite its resorbing surface being exposed to extremely high levels of ambient Ca. Recently our studies have provided evidence of continuous transcellular Ca disposal, suggesting that osteoclasts are able to prevent Ca accumulation within the resorptive hemivacuole. It has also been shown that matrix protein degradation products that accumulate within the osteoclast resorptive vacuole are also undergoing transcellular transport by transcytosis. However, both experimental evidence and theoretical considerations suggest that transcellular transport of Ca and matrix protein is likely to occur via distinct routes. In light of these considerations, we are able to provide convincing explanations for the apparent anomalies of osteoclast intracellular [Ca] responses to a variety of endocrine stimuli. The understanding of the mechanisms involved in Ca handling by osteoclasts indicates the lack of a simple link between osteoclast function and changes in overall cytosolic [Ca].

KL-RAP: An Efficient Key-Less RFID Authentication Protocol Based on ECDLP for Consumer Warehouse Management System

Elliptic Curve Cryptography (ECC)-based authenti-cation schemes for the Radio-frequency identification (RFID) environment have emerged as a very safe, secure, and robust candidate of mutual authentication. However, the limited resource availability in a passive tag makes such schemes difficult to realize in practice. Public/private key pair generation, storage, and the computation using those keys are the major bottlenecks towards the faster and efficient design of such schemes. Therefore, we have designed our scheme without using public/private key pairs. We only utilize the Elliptic Curve Discrete Logarithm Problem (ECDLP) property for the realization of our key-less scheme on the secure elliptic curves. Our scheme is primarily aimed at efficient implementation of authentication schemes in Warehouse Management System (WMS), where the data is stored in local servers. This new idea helps to save the memory space in the tags and the server. Moreover, the computation cost also reduces to a great extent in comparison to other schemes. We have compared our scheme with several other schemes and found it efficient in terms of storage cost as well. The simulation result of our scheme with the popular automated software validation tool, Scyther, shows that it is safe from different possible attacks.
