Successful social games and their super-power: Big data analytics

This article is a short presentation of big data analysis and game analysis. The paper describes the case of social games, and observes the huge improvement that big data analysis has on social games and their success. It also contains a presentation of PokĂSmon GO, and its evolution on the market, from launch until today. A set of metrics and algorithms are proposed, that can be used to improve game features and monetization. In the last section, I apply a Naive Bayes classifier, using WEKA, on a set of data collected from social media networks, to predict how using a game that implies walking influences the amount of daily steps a player makes.
Beyond SOD1: Detailed Characterisation of a TDP-43 Transgenic Mouse Model of Motor Neurone Disease

Background: Motor neurone disease (MND) is a fatal, progressive, neurodegenerative disease causing muscle weakness, spasticity and paralysis. No small molecule drugs have translated from MND mouse models to MND patients, possibly because of MND mouse models being based on SOD1 mutations, representing only a small proportion of patients. Nearly all non-SOD1 patients have TDP-43 pathology, whereas SOD1 patients do not, suggesting a mechanistic difference between non-SOD1 and SOD1-related MND. A TDP-43 model may be more representative of the patient population and lead to better translation of treatments. There is also a need for translational biomarkers in MND to further improve translation. Methods: A colony of mice transgenic for mutant human TDP-43 (TDP-43Q331K) was established, alongside a control line (TDP-43WT). The mice were characterised for motor function including rotarod, gait analysis, and neuroscoring. Immunohistochemical, mRNA and protein level studies were also carried out. Increased weight was noted in the TDP-43Q331K mice, leading to a study of voluntary activity and food intake. A further study investigated electrophysiological parameters, apathy, and riluzole treatment. Preclinical 31P-MRS imaging was carried out in SOD1G93A mice in an attempt to find a translational biomarker. Results: TDP-43Q331K mice developed a progressive phenotype, whilst TDP-43WT mice showed none. TDP-43Q331K mice showed signs of motor dysfunction, increased TDP-43 in the nucleus and cytoplasm of motor neurons (supported by increased mRNA and protein levels), astrogliosis, and microgliosis in the spinal cord, apathy, overeating and electrophysiological findings suggestive of denervation. Riluzole may have had a mild treatment effect in TDP-43Q331K mice, measured by electrophysiology. No conclusions could be drawn from the preclinical 31P-MRS due to animal welfare issues. Conclusions: TDP-43Q331K mice have a progressive motor phenotype of low variability with reliable motor, pathological and cognitive readouts of disease and may provide a useful model for evaluating potential neuroprotective therapies.
K@RT: An Aspect-Oriented and Model-Oriented Framework for Dynamic Software Product Lines ⋆

Software systems should often propose continuous services and can- not easily be stopped. However, in order to meet new requirements from the user or the marketing, systems should be able to evolve in order to propose new ser- vices or modify existing ones. Adapting software systems at runtime is not an easy task and should be realize with attention. In this paper, we present K@RT, our generic and extensible framework for managing dynamic software product lines. K@RT is composed of three parts: i) a generic and extensible metamodel for describing running systems at a high-level of abstraction, ii) a set of meta- aspects that extends the generic metamodel with constraint checking, supervis- ing and connections with execution platforms iii) some platform-specific causal connections that allow us to supervise systems running on different execution platforms.
ASSESSMENT OF PREVALENCE OF DEPRESSION IN CARDIAC PATIENTS AND ITS ASSOCIATION WITH THE USE OF BETA-BLOCKERS AND STATINS

Objective: The objective of the study is to assess the prevalence of depression among patients with cardiovascular disease and its association with the use of β-blockers and statins.Methods: This is a prospective observational study conducted at a corporate hospital, Hyderabad, Telangana, India, for a period of 6 months. 250 cardiac patients above 16 years are included in the study. The required data are collected from the patients through direct interview using standard questionnaires and also from patients’ respective case sheets. The acquired data are evaluated based on the standard questionnaires Patient Health Questionnaire-9 (PHQ-9) and Beck Depression Inventory-II (BDI-II) scales; used to diagnose the severity of depression in cardiac patients.Results: Prevalence of minor to major depressive symptoms according to BDI-II was found to be 17.2%. Prevalence of minor to major depressive symptoms according to PHQ-9 was found to be 19.2%. Among male patients, 13% showed depressive symptoms, whereas among female patients 25% showed depressive symptoms. Among the patients coadministering beta-blockers and statins, 15% were depressed according to BDI-II, and 16% were depressed according to PHQ-9 at visit. After 1 month (first follow-up), the percentage increased by 8% (for BDI-II)-12% (for PHQ-9) and remains almost the same at the second follow-up. As per BDI-II and PHQ-9 scores, the percentage of patients with minor to major depression among the patients using only beta-blockers decreased significantly from the time of visit to the second follow-up. The percentage of patients with minor to major depression among the patients using only statins increased significantly from the time of visit to second follow-up.Conclusion: Prevalence of minor to major depression according to BDI-II was found to be 17%, whereas according to PHQ-9, it was found to be 20% in patients with cardiovascular disease. Cardiovascular diseases have been more prevalent in men than in women, whereas depressive symptoms have been more prevalent in women than in men. Patients using only β-blockers showed a decrease in symptoms of depression. Whereas statins have shown to increase the chances of depression slightly which is often negligible, atorvastatin was associated with a higher level of depression when compared to rosuvastatin. Controversies still exist that statins decrease risk of depression.
Adapting video compression to new formats

Les nouvelles techniques de compression video doivent integrer un haut niveau d'adaptabilite, a la fois en terme de bande passante reseau, de scalabilite des formats (taille d'images, espace de couleur…) et de compatibilite avec l'existant. Dans ce contexte, cette these regroupe des etudes menees en lien avec le standard HEVC. Dans une premiere partie, plusieurs adaptations qui exploitent les proprietes du signal et qui sont mises en place lors de la creation du bit-stream sont explorees. L'etude d'un nouveau partitionnement des images pour mieux s'ajuster aux frontieres reelles du mouvement permet des gains significatifs. Ce principe est etendu a la modelisation long-terme du mouvement a l'aide de trajectoires. Nous montrons que l'on peut aussi exploiter la correlation inter-composantes des images et compenser les variations de luminance inter-images pour augmenter l'efficacite de la compression. Dans une seconde partie, des adaptations realisees sur des flux video compresses existants et qui s'appuient sur des proprietes de flexibilite intrinseque de certains bit-streams sont investiguees. En particulier, un nouveau type de codage scalable qui supporte des espaces de couleur differents est propose. De ces travaux, nous derivons des metadata et un modele associe pour operer un remapping couleur generique des images. Le stream-switching est aussi explore comme une application particuliere du codage scalable. Plusieurs de ces techniques ont ete proposees a MPEG. Certaines ont ete adoptees dans le standard HEVC et aussi dans la nouvelle norme UHD Blu-ray Disc. Nous avons investigue des methodes variees pour adapter le codage de la video aux differentes conditions de distribution et aux specificites de certains contenus. Suivant les scenarios, on peut selectionner et combiner plusieurs d'entre elles pour repondre au mieux aux besoins des applications.
Scalable and Flexible OpenFlow-based Distributed Rate Limiting

Explosive growth of the new style computers such as cellular phones, smartphones and tablets lead the strong demand for the large scale internet serivces, which are often taking an important role in the society. The massive scale datacenters which comprise tens or hundreds of thousands commodity computers achieve these services automating the dynamic management of the computational resources by the virtualization technologies and distributed systems. This cloud computing paradigm provides agility and cost effective solutions to users. Although the operations on computational resources are highly automated, the network facilities are still managed manually since they do not provide flexible interfaces. In addition the limitation of existing network solutions prevent building the massive scale network distributed in regions in cheap price. To solve the problems network virtualization with software-defined network (SDN) is emerging. It provides programmable interfaces to the network facilities and enables dynamic deployment of the virtual machine (VM) instances. On the other hand, distributed rate limiting (DRL) was proposed to control the traffic of cloud services distributed in racks, datacenters and regions. DRL paradigm enables cloud service providers to provision the traffic on the multi-tenant environment in the fair manner and introduces new billing system on the network loads. However the DRL requires the configurations and implementation of rate limiting and consensus agreement algorithms to switches, which need to be operated manually. In this thesis we propose the DRL system on the virtualized network to achieve fully automated network operations. Our approach contributes to the realization of the more cost effective, scalable and flexible datacenter network and enhances the agility on the deployment of network facilities. 概要 携帯電話,スマートフォンそしてタブレットなどの新しい形のコンピュータの爆発的普 及は大規模Webサービスへの要求を強めており,それらのWebサービスはしばしば社会 において重要な役割を担っている. それらのサービスを支える大規模データセンターは数 万,数十万台のコモディティコンピュータから構成されており,仮想化技術や分散システム によって計算資源の動的な管理を自動化している. このクラウドコンピューティングという パラダイムはユーザに安価で即時的な計算資源を提供している. しかし計算資源に関するオペレーションは高度に自動化されているものの,柔軟なイン タフェースが提供されていないためにネットワーク設備の管理はは未だに人の手によって行 なわれている. 加えて既存のネットワーク機器の制限が分散した安価な大規模データセン ターの実現を妨げている. これらの問題を解決するために Software-Defined Netowrk によ るネットワーク仮想化が登場してきた. ネットワーク仮想化はネットワーク機器に対するプ ログラマブルなインタフェースを提供しVirtual Machineインスタンスの動的なデプロイメ ントを可能にする. 一方,複数の場所に分散するクラウドサービスのトラフィックを制御するために Distributed Rate Limiting (DRL)が提案された. DRLによってクラウドサービスプロバイダ は公平な立場でマルチテナント環境のトラフィックのプロビジョニングを行なったり,ネッ トワークの使用量に応じた課金を行うことができる. しかし,DRLは帯域制御アルゴリズ ムやコンセンサスアルゴリズムの実装および設定を手動で行なう必要がある. 本論文で我々は仮想ネットワーク環境で完全に自動化されたDRLシステムを提案する. 我々の提案手法は,より安価で柔軟な大規模データセンタおよびネットワーク機器のデプロ イメントのアジャイル化に貢献することが期待される.
Voice Print Recognition Algorithm Based on the Natural Language Processing

The problem of the accurate recognition of human voiceprint was researched in this paper.A voiceprint recognition algorithm was put forward based on semantic features and the United States Mel frequency cepstral coefficients features.Using the MFCC,the frequency characteristics of the speech were extracted accurately,then changed into the semantic features of the natural language environment.Because the semantic features are not affected by objective factors,so the influence of the noise signal on the speech signal was reduced,realizing the accurate recognition for speech characteristics.Experimental results show that the correct recognition of differentiated vehicle images was realized by using the improved algorithm and the accuracy of the recognition was also improved.
Efectividad de la auriculoterapia en el tratamiento de la ansiedad en el adulto mayor

Se realizo un estudio experimental, para determinar la efectividad de la auriculoterapia en pacientes adultos mayores con ansiedad, comparada con el tratamiento convencional, remitidos a la consulta de Medicina Tradicional y Natural del policlinico “Julio Antonio Mella”, Camaguey, Cuba; en el periodo comprendido entre enero y diciembre de 2013, previa valoracion por psiquiatria. El universo fue de 520 pacientes adultos mayores con diagnostico de ansiedad generalizada, remitidos de la consulta de psiquiatria de la entidad antes mencionada. La muestra quedo constituida por 60 de ellos, que ademas no habian ingerido psicofarmacos en un periodo menor a seis semanas. Se formaron dos grupos, uno control (30), con tratamiento convencional, y otro de estudio (30), con auriculoterapia. La asignacion de los sujetos a cada grupo fue por el metodo aleatorio simple. Al grupo de estudio se le aplico esquema de tratamiento con auriculoterapia y al grupo control se le aplico tratamiento farmacologico convencional. En los resultados obtenidos se observo que el grupo de edades mas afectadas por la ansiedad fue el de 70 a 74 anos y predomino el sexo femenino. El insomnio, la irritabilidad y la dificultad de memoria fueron los sintomas que mas se observaron en el estudio. Al finalizar el tratamiento los sintomas disminuyeron de forma mas apreciable en el grupo tratado con auriculoterapia. La auriculoterapia fue mas eficaz en el tratamiento de la ansiedad y es una tecnica practicamente inocua, con la cual se puede disminuir la utilizacion de psicofarmacos
Análisis del impacto presupuestario de la implantación de medidas de ahorro de sangre en cirugía de urgencia

Fundamento y objetivo El objetivo de este trabajo es estudiar la relacion coste-efectividad y el impacto presupuestario que supone para un hospital el establecimiento de un programa de ahorro de sangre alogenica en pacientes ancianos intervenidos quirurgicamente de fractura de cadera pertrocanterea. Pacientes y metodo Se incluyo 2 grupos de pacientes. Grupo 1: pacientes sin tratamiento farmacologico de la anemia perioperatoria o que recibieron hierro oral; y Grupo 2: pacientes incluidos en un programa de ahorro de sangre con criterios transfusionales restrictivos y tratamiento con hierro sacarato intravenoso y epoetina alfa. Se definieron como parametros de efectividad el porcentaje de transfusiones y el numero de concentrados de hematies transfundidos, la duracion de la estancia postoperatoria y el porcentaje de infeccion hospitalaria. Los costes de tratamiento se calcularon usando el precio de venta a farmacia (PVF) de los farmacos y los costes de unidades de sangre transfundidas y cruzadas en el ano 2003 segun tarifas oficiales. Se utilizo el ano 2003 para establecer la poblacion prevalente. Resultados Se incluyo a 144 pacientes estudiados de marzo a septiembre de 2003 (101 en el grupo 1 y 43 en el grupo 2). Ambos grupos fueron comparables en sexo, edad, tiempo prequirurgico, riesgo quirurgico (ASA) y valores de hemoglobina al ingreso. Los pacientes incluidos en el programa de ahorro de sangre recibieron menos transfusiones y presentaron menos infecciones, aunque la estancia posquirurgica fue similar en ambos grupos. El impacto presupuestario fue 239.148 euros (intervalo de confianza [IC] del 95%, 202.312-311.980 euros) en el grupo 1 y 311.980 euros (IC del 95%, 275.288-348.672 euros) en el programa de ahorro de sangre. La generalizacion del ahorro de sangre a toda la poblacion prevalente en 2003 (400 pacientes) supondria un aumento medio de costes para el hospital de 72.832 euros, se evitaria transfusions a 92 pacientes y se ahorraria 328 concentrados de hematies y 70 infecciones hospitalarias. Conclusiones El aumento en el gasto que implica la generalizacion del uso del hierro sacarato intravenoso y la epoetina alfa no se considera especialmente gravoso para el presupuesto del hospital. Este incremento en el coste evita transfusiones sanguineas, bolsas de sangre e infecciones hospitalarias, pero no queda del todo claro en que supuestos disminuye la estancia media, punto que se deberia analizar con estudios prospectivos o de mayor tamano muestral.

Noise reduction in audio signals based on the perceptual coding approach

A new concept for the reduction of noise affecting audio signals transmitted in telecommunication channels is proposed. This concept is exploiting some features of the human auditory system. A strong subjective effect of noise suppression in noisy audio can be obtained by uplifting the masking thresholds above the estimated level of the noisy components or by reducing this level in such a way that the components be maintained just below the masking thresholds. The foundations of the engineered method together with the appropriate algorithms are described. A discussion on the results of experiments carried out and some conclusions are also included. The main focus is put on the perceptual foundations of the noise reduction method.

Investigation into Building an OpenFlow-enabled BNG

In carrier-grade Internet Service Provider (ISP) networks the Broadband Network Gateway (BNG) is a specialised network server which sits at the core of an ISP network. The responsibilities of the BNG include the facilitation and aggregation of active user sessions from the ISP’s access network, and providing Internet Protocol (IP) connectivity through the ISP backbone network to the Internet. In a typical ISP carrier network, the BNG is one of the most expensive appliances and carries a high degree of responsibility. Due to the cost, it is common for there be only a single centralised BNG, which presents a singular point of failure (SPOF) for all ISP subscriber access to the Internet. This project aims to investigate whether the centralised BNG model is able to be redesigned using a new approach to computer networking called Software Defined Networking (SDN). Using SDN and the OpenFlow protocol will allow for the separation of the traffic forwarding logic of a switch from the data plane, enabling that logic to be moved into an application running in software. This results in a much more software oriented approach to network design and the control and configuration of switches. This project aims to investigate the removal of singular dependence on the centralised BNG model by distributing the functionality of a BNG among a network of commodity switches. There is a strong focus on implementing support for a number of important session establishment protocols and how these can be used to make necessary dynamic traffic forwarding decisions, as well as the investigation of a carrier-grade distributed software controller.
A Two-Stage Service Replica Strategy for Business Process Efficiency Optimization in Community Cloud

Business process that facilitates the organization cooperation and resource sharing plays an important role in Community cloud (Comc). The nature of applications and decentralized infrastructure in Comc make it a big challenge in ensuring the execution efficiency of business process, especially when the business requests are in high concurrency. We present a two-stage service replica strategy to improve the execution efficiency of business process by shortening the response time of request to single service and reducing interaction time among distributed services. We initially utilize the social network property of services to pre-allocate the replicas of key services. After that, queueing model is adopted to determine the required additional replicas according to the quantity and frequency of user requests, then schedule service replicas and requests dynamically. Experiments demonstrate the effectiveness of the proposed strategy.
