Pandemic Influenza and Mathematical Modelling

The outbreaks of Avian Influenza H5N1 the recent years has increased our attention to a possible Pandemic Influenza. Mindful of the last century's pandemics, we fear that changes in the virus' surface antigens can cause a new virus capable of transmitting between humans. Statisticians use mathematical modelling as an instrument for predicting the pattern and intensity of the spreading of a pandemic; models can also help estimating the effects of measures such as antiviral drugs, vaccination and quarantines. Though simplified models have their limitations, it is obvious that even simple models can be a powerful tool in pandemic preparations. How should the governments and health care workers prepare for a possible pandemic? A lot of studies try to answer this, some using mathematical modelling. In this paper, I will review some of the debate on this subject. It seems to be generally agreed that we still need to learn more about influenza, and the WHO urges all countries to prepare plans for the handling of a possible pandemic. Secondly, I report the results of attempts to estimate R0values from outbreaks of Norwegian seasonal influenza epidemics. My estimations show expected values of R0, but unexpectedly small values of latency and infectious periods. Finally, I have made an SEIR-model to simulate a possible pandemic, illustrating how differences in the viral pathogenicity and our efforts to reduce spread might alter the course of the pandemic.
Utilizing the Globalstar Network for Satellite Communications in Low Earth Orbit

In the Spring of 2016 sci_Zone in partnership the Boeing will be flight testing and certifying the QuickSAT/Vehicle Management System (VMS), the prototype of the FRNCS-P flight computer platform and the LinkStar global communications radio on the Boeing RADSat Satellite. The RADSat Satellite is a 2U CubeSAT that will be deployed from the International Space Station via the NanoRacks Program. A key piece of this mission will be to test and demonstrate full duplex communications between the satellite and ground via the Globalstar satellite network utilizing the LinkStar radio architecture. Globalstar is a constellation of 32 satellites in LEO providing global data and voice services for a range of uses including oil rigs, shipping containers, gas pipelines and supporting remote communications. Our research focused on adapting the Globalstar GSP1720 modem and creating the LinkStar radio architecture for use in space. Work included marrying the modem with modified BeagleBone Black ARM based computer which utilizes an embedded Linux based operating system to control the satellite and manage the radio architecture. Work also included the development of an open source flight management system QuickSAT/Vehicle Management System (VMS) along with the Communicator set of APIs. QuickSAT/VMS is a flexible open source flight management system tailored for cubesats and other types of small satellites. The architecture provides for basic satellite command and control, data management, scheduling, event handling and complete software based radio tool set. The framework allows for users to define custom classes of components (such as radios, magnetometers and other sensors) without modifying the core architecture. The architecture provides a robust data management architecture, not only managing the vehicle configuration and schedule, but also logging system messages, errors and events, and storing data as needed into separate recording sessions. Communicator is a set of APIs, allowing for the integration of several radios on one satellite including the LinkStar duplex radio and LinkStar-STX3 simplex radio. Communicator allows the user to add custom modules to the core architecture, and allows the user to set parameters to define how the radios will work together. Models show LinkStar will provide up to 50% continuous coverage – both data download AND upload through a secure internet link. For the LinkStar-STX3 simplex radio, over 95% downlink coverage can be provided. In both radio systems the data itself is further encrypted to insure the information transmitted to and from a satellite is secure. In this briefing we will discuss and demonstrate QuickSAT/VMS and Communicator, FRNCS-P and how they work with the LinkStar radio, and the operation and integration of the LinkStar radio. We will also cover the RADSat mission including mission operations.
Comedy and Critique

Comedy & Critique is a sociological inquiry which seeks to engage with the art-world of the stand-up comedian as well as providing an interpretation of comedic works. It demonstrates a correspondence between what is happening within stand-up comedy and what is going on in the society from which the comic material arises. The book demonstrates that stand-up comedians are engaged in a proto-sociological enterprise, a method of ‘doing’ sociology. Comedian’s material may be viewed as a comedic acting out of forms of sociological knowledge, an act which is self-driven and intra-personal. Stand-up comedians came to their proto-sociology as stand-up in Britain moved from the fringes of entertainment in working man’s clubs to Fringe theatre. Through this transition stand-up became a space where a ‘New Left’ politics of anti-racism, feminism and a queering of self and society was both lived and artfully positioned. By exploring the ‘art of stand-up’, as a modernist art-form and professionalised industry, the book argues that stand-up is the art of building and improvising social relations.
Construct Demo Input Deck

This technical report describes a demo input deck for Construct, the CASOS dynamic network simulation tool. It describes an example problem – understanding the difference in information diffusion patterns when bridging agents span two otherwise separate groups – and then how such a simulation would be simulated using Construct. In so doing, it describes the way in which data is supplied to Construct. Additionally, this report also describes how to run the simulation using the command line, and ways in which the simulation could be extended to analyze other problems.
Design of Power System Stabilizer using Intelligent Controller

The design of two level power system stabilizer (PSS) is discussed in this paper. First level is conventional PSS, while the second level is designed using following two methods: fuzzy inference system (FIS) and adaptive neuro-fuzzy inference system (ANFIS). Speed deviation and derivative of speed deviation, the rotor angle of synchronous generator are taken as the input to the controller and voltage signal is the output of the controller. The main function of the conventional power system stabilizers is to enhance the damping of low frequency oscillations in power system, while the power system stabilizer which is designed using fuzzy inference system and adaptive neuro-fuzzy inference system improves the total response to achieve the required results. This technique is applied on a single machine infinite bus (SMIB) power system. The adaptive neuro-fuzzy inference system damps out the low frequency oscillations and enhances the power system dynamic stability in the better manner than the conventional power system stabilizer. Keywords— PSS, Fuzzy logic controller, ANFIS, SMIB.
Negative refraction of excitations in the Bose-Hubbard model

Ultracold atoms in optical lattices provide a unique opportunity to study Bose-Hubbard physics. In this work we show that by considering a spatially varying on-site interaction it is possible to manipulate the motion of excitations above the Mott phase in a Bose-Hubbard system. Specifically, we show that it is possible to "engineer" regimes where excitations will negatively refract, facilitating the construction of a flat lens.
Validation Procedures for Equations, Algorithms, and Submodels

Abstract : Verification and validation is a continuous activity throughout the entire modeling and simulation life cycle. This document provides a template to address general validation procedures for equations, algorithms, and submodels that form the underlying analysis found in vulnerability/lethality software tools. This template is considered a bottom-up approach for validation of a submodel as a stand-alone model as opposed to a top-down approach for validation of the overall model for live-fire tests.

Real-time compressive sensing for small low power sensors: maximizing system performance in power impoverished environments

Small, light and low power sensors have been utilized in a growing number of modern applications. With rapid growth of circuit integration, we can fabricate more transistors onto a smaller area of silicon, providing sensors with increased computational capability. However, as the miniaturization continues, these sensors face constraints in size, weight and power: Despite rapid circuit integration, the size of the non-electronic components of the sensor such as batteries, optical and mechanical structures cannot be reduced following similar trend. Power consumption of the sensor must also be kept low to ensure long battery life and minimal heat dissipation. Due to these constraints, design for Size Weight and Power (SWaP) becomes a major challenge for miniature sensors. Compressed Sensing (CS), a signal processing theory, has shed light to SWaP constraints. CS theory suggests that the amount of samples a sensor must acquire to reconstruct a sparse signal can be much less than signal’s Nyquist rate. Sparse signal is a signal that can be represented using only a few coefficients in a transform domain. In fact, in CS, sampling rate is independent from signal frequency, but is ii
Cellular Automata Music: An Interdisciplinary Project

Abstract Researchers from many branches of scientific knowledge have been attracted by the organizational principles found in music. Also music has been an interesting domain for the application of new discoveries in science, inviting people to combine artistic creativity with scientific methods. A new environment has emerged in the domain of musical composition; what is now called computer music. This project is an attempt to identify correlations among different disciplines such as biology, crystallography, computing and fluid mechanics in order to investigate the possibility of composing music inspired by a framework of interdisciplinary knowledge. We have selected cellular automata to play the central role on our research due to the fact that they have been used to model a wide range of scientific phenomena, such as chemical reactions, dynamic systems, chaotic systems, genetics, crystal growth, and so forth. This paper describes a prototype implementation of an experimental system for cellular automat.
AGRIX: An Ontology Based Agricultural Expertise Retrieval Framework

Generally, information retrieval (IR) performs keyword search based on the user query to find a set of relevant documents. In the domain of agricultural expertise retrieval, the goal is to find a group of experts who has knowledge in agriculture (by using publications as the evidence) specified by the input query. Typical publication IR systems could sometimes return the search result sets, which consist of a huge amount of publications. Some of the returned publications are not relevant to the individual user’s information need. In this paper, an ontology based agricultural expertise retrieval framework called AGRIX is proposed with the focus on the ontology creation to cover three following aspects: (1) expert profiles and publications, (2) type of plants and (3) problem solving. To build the ontology model, we used a set of publications (1,249 records) which was collected from the Thai national AGRIS center, Bureau of Library Kasetsart University. In addition, a set of inference rules is created to support the expertise retrieval task. By using AGRIX to implement an agricultural expertise retrieval, users can search for experts in two perspectives, plant (e.g., rice, sugar canes) and problem solving (e.g., plant diseases, fertilizers).
Actigraphy can be used to Quantify Sleep in the Perioperative Period in Women Undergoing Breast Cancer Surgery: A Validation Study

Actigraphy can be used to Quantify Sleep in the Perioperative Period in Women Undergoing Breast Cancer Surgery: A Validation Study Background: Sleep disturbances after surgery are frequent and a valid tool to quantify these is warranted. We set out to make an epoch by epoch validation of actigraphy against polysomnography (PSG) for detection of sleep and wake in women undergoing surgery for breast cancer. Methods: Twelve patients, 30-70 years, undergoing a lumpectomy were included. Patients simultaneously wore an actigraph and a polysomnograph on the preoperative night (PREOP), the first postoperative night (PO1), and the fourteenth postoperative night (PO14). The outcome measures were sensitivity (i.e. the amount of correctly scored sleep) and specificity (i.e. the amount of correctly scored wake).
Design and Implementation of File Authentication System using Timestamp Mechanism for a Distributed File System

Gfarm, a distributed file system for a petabyte scale data intensive computing or a shared storage for big data, is gradually used as system infrastructure in science research or business. It is a promising file system, however, it does not provide a function to prevent from data falsification. We implemented a file authentication system using timestamp mechanism to work with Gfarm. This paper reports the way to combine timestamp mechanism with Gfarm and the evaluated results using dummy files based on real files in a cloud service using Gfarm. Keyword distributed file system, cloud security, file authenticity, timestamp authentication
Comparison of various Elicitation Techniques and Requirement Prioritisation Techniques

Software engineering research has been, and still is criticised as being immature and unscientific due to lack of evaluation. However, software engineering community is now focusing more on empirical research. One of the major activities within the requirements engineering process is to use requirements elicitation and requirements prioritization that helps to focus on the most important requirements. Requirement elicitation is recognized as one of the most critical knowledge intensive activities of the development of software. Requirements prioritization aims at identifying the most important requirements for a system . There are many elicitation and prioritization techniques available; still there is lack of evidence of which technique to prefer. The reasons could be the differences in contexts, measurement of variables and usage of data sets. In this paper, the area of requirements elicitation and prioritization has been systematically reviewed in order to assess what evidence regarding different techniques exist.
Distinguishing the Trees from the Forest: Applying Cluster Analysis to Thematic Qualitative Data

Qualitative data analysis requires organizing and synthesizing often large quantities of text. In many cases, this analysis entails negotiating the interplay between raw data, semantic themes or codes, and the overarching conceptual framework. In this article, the authors use a case study, which examines HIV vaccine efficacy trial participants' discourse, to demonstrate how cluster analysis can be used to aid in the analysis of large qualitative data sets. After briefly reviewing the systematic approaches to qualitative analysis and describing the project background, the authors present an example of how a hierarchical cluster technique can be incorporated into a multistage thematic analysis.
Design and Evaluation of a Gesture-Controlled System for Interactive Manipulation of Medical Images and 3D Models

This work presents the design and evaluation of a gesture-controlled system for interactive manipulation of radiological images and 3D models using the Kinect device. Several abstractions have been implemented and refactored to improve the system performance, making the application simpler, at an affordable cost. Additionally, specific gestures to change the visualization settings of 3D models represented by layers were also successfully modeled. Further, we have conducted systematic and detailed usability testings with users to determine quantitative performance measures and qualitative analysis (usefulness, visual quality of the interface, ease of learning, ease of use, 3D spatial perception, level of interactivity, mental and physical fatigue, effectiveness and satisfaction). The results show that the participants are able to perform the tasks of search, selection and manipulation of 2D images (zoom in/out and translations) and 3D models (zoom in/out and rotations), quickly and accurately, demonstrating the usefulness of the system as a possible effective and competitive alternative solution, to the traditional use of the negatoscope.
Tsallis' Statistics without probability distributions. REPLY to Comment on"Possible Divergences in Tsallis' Thermostatistics"

In a recent letter (EPL, 104 (2013) 60003) we suggested a way to avoid divergences inherent to the formulation of nonextensive statistical mechanics. They can be eliminated via the use of a q-Laplace transformation, which was illustrated for the case of the harmonic oscillator. Lutsko and Boon now contend, in an interesting comment, that our new formulation raises questions that they carefully discuss. Here we elaborate an explanation of the contents of (EPL, 104 (2013) 60003) that permits to appreciate our original Letter in a more positive fashion. PACS 05.20. -y, 05.70. Ce, 05.90. +m It is well known that, for obtaining the partition function Z, two alternative routes can be followed: • the “natural” one, given by Z’s definition in terms of a sum over “unnormalized” probabilities, and • Z as the Laplace Transform of the energy density. In the orthodox Boltzmann-Gibbs Statistical Mechanics, that uses the ordinary exponential function, the two routes yield the same result. We proved in [1] that such is NOT the case for Tsallis’ thermostatistics, for which the first alternative (use of a probability distribution) diverges in one or
Writing Systems Software in a Functional Language

Current practices for developing systems software usually rely on fairly low-level programming languages and tools. As an alternative, our group has been investigating the possibility of using a high-level functional language, Haskell, for kernel and device driver construction, with the hope that it will allow us to produce more reliable and secure software. In this paper, we describe our experience developing a prototype operating system, House, in which the kernel, device drivers, and even a simple GUI, are all written in Haskell. The House system demonstrates that it is indeed possible to construct systems software in a functional language. However, it also suggests some ideas for a new Haskell dialect with features that target specic needs in this domain, including strongly typed support for low-level data structures and facilities for explicit memory accounting.
Handling Wolof clitics in LFG

Clitics often involve intricate interaction between different grammar components, including morphophonology, syntax and information structure. This phenomenon is challenging from a general theoretical perspective. In Wolof, clitization has been investigated using a transformational approach. In contrast, this paper proposes a formal analysis of Wolof clitics using a non-transformational model based on the Lexical Functional Grammar (LFG) theory. This approach needs no special rule for verb movements at all and preserves the lexical integrity of words. For sake of concreteness, the theoretical purpose is combined with an implementation that illustrates how the LFG formalism is well suited to a precise treatment of clitics.
COLOR AND SCULPTURE IN SOUTH ASIA

Until Susanne Ebbinghaus of the Harvard Art Museum organized the symposium "Su perficial? Approaches to Painted Sculpture," polychromy had not been an object of my research on South Asian sculpture. Yet I soon realized that in most periods, South Asian sculpture and architecture had been covered in strong colors and that the tawny sandstone and cool granite masterpieces in mono chrome that I had studied for the last few
Establishing reorder points in the (S,c,s) coordinated control system under compound Poisson demand

Abstract This paper is concerned with the coordinated control of a group of inventoried items in order to reduce the costs of replenishments. The specific control system considered is what is denoted as an (S,c,s) system. The very general case of compound Poisson demand is considered. In earlier work a procedure was developed for finding the order-up-to levels (i.e. the Ss) and the can-order points (i.e. the cs) for the case of a negligible lead time. Taking these quantities as input an algorithm is developed for finding the must-order points (i.e the.s values) so as to satisfy one of two types of service constraints specified item by item. The results of two numerical illustrations are also shown.
HISTOPATHOLOGIC MANIFESTATIONS OF BRAIN, HEART, LUNG AND ILEUM OF MALE RATS DOSED COUNTERFEIT SILDENAFIL CITRATE

Sildenafil citrate is an orally administered drug used for the treatment of male impotence through inhibition of phosphodiesterase-5 in the corpus cavernosum. While drugs like analgesics, antibiotics, and anti-malarials are the most commonly found counterfeit drugs in the developing countries; the problem of counterfeit sildenafil citrate is a world-wide phenomenon. Though the liver and kidney are the sites/routes of its metabolism and excretion, the penis is the target organ of its action. With this study the impact of sildenafil citrate counterfeit on the brain, heart, lung and ileum in Wistar rats is being investigated. Twenty one male rats (250 g), randomly distributed to 3 groups of 7 rats each were used for the study. While rats in the first group were doused with 25 mg/kg of fake sildenafil, those in the second group were doused with 25 mg/kg BW of genuine sildenafil, and the third group served as the control and was administered with distilled water. Sections of lung, heart, brain, and ileum were processed and stained with haematoxylin and eosin (H & E). The slides were viewed under the microscope at magnification of ×400. Results of the study revealed that while control rats and rats dosed with genuine drug manifested no visible lesions in all tissues examined, fake drug administered rats features the following histopathological manifestations brain (severe meningeal congestion and haemorrhage); heart (congestion of the coronary vessels); lung (mild proliferation of alveolar pneumocytes); and ileum (erosion and degeneration of mucosal surface). From the results of the study, it is evident that the counterfeit sildenafil citrate used for the study was toxic to tissues. Therefore, no effort should be spared in discouraging the sale, distribution and consumption of fake drugs.
