Leadership in an online multiplayer strategy game: case - Illuria

This paper looks at leadership communication in the context of online multiplayer games and the groups that operate within them. In multiplayer games promoting teamwork and long-term cooperation, issues of management and leadership are prevalent. The study explores the experiences that members of multiplayer communities have towards leadership in multiplayer games by looking at one specific case of organised team play within the framework of a turn-based online strategy game. The data utilised in this study consist of themed player interviews conducted via e-mail. The analysis proposes three central dimensions that emerged from the data. These were labelled: (1) the leader as primus motor, (2) the necessity of authority and (3) the discourse of leadership as work. At the end of this paper, directions for future research are outlined.
Ankle Arthritis

The ankle joint is subjected to more weight-bearing force per square centimeter and is more commonly injured than any other joint in the body, but the prevalence of symptomatic arthritis at the ankle is approximately nine times lower than that at the knee and hip. Various mechanical, biochemical, and anatomical particularities of the ankle account for its apparent resilience to the processes of aging and trauma. Once arthritis has developed, treatment includes medication, bracing, shoe modifications, arthroscopic débridement, arthrodesis, and/or arthroplasty. Arthrodesis is regarded as the preferred treatment in the presence of end-stage arthritis and failure of conservative management. Since Albert’s first description in 1879, numerous techniques for achieving a fusion have been described, and the general principles of alleviating pain, correcting deformities, and maintaining hindfoot stability remain unchanged. Modern techniques have yielded good intermediate-term results and can provide an active individual with a functional extremity. However, the reliability of long-term outcomes has been questioned. Moreover, major modifications in the design and techniques of arthroplasties have challenged the notion that arthrodesis is the treatment of choice. In this review, we will provide an overview of the pathophysiology of ankle arthritis and the biomechanics of the ankle joint. We will then review the current indications, techniques, results, and complications of arthrodesis and arthroplasty with an emphasis on recent advances.
Simultaneous rotation and distance measurement using multiband circularly polarized radio link

The paper proposes a method for simultaneous measurement of rotation and distance by using a multi-band circularly polarized radio links. The method is realized using a standard dual-band patch antenna, operating at 1.58 GHz and 2.27 GHz, with respective axial ratios of 1.7 dB and 1.0 dB. Both link distance and antenna rotation were varied from a reference position/orientation from −40 mm to +40 mm and from 0° to 360°, producing a total set of 125 samples. For a noiseless link the distance change and rotation were predicted with respective mean errors of 1.9 mm and 7.3°.
Study of optimal control strategy of electric machines used in Plug-in Hybrid Electric Vehicles

This paper presents simulation of ANN control approach of electric machine (EM) used in Plug-in Hybrid Electric Vehicle (PHEV). The EM is constructed in MATLAB/Simulink and the feedback closed-loop control system of ANN controller has been developed. A power reference curve has been used as reference for the EM that represents the load demand of the PHEV. The control system has been simulated to obtain optimal control parameters of the system that can optimally track the power reference curve. The proposed ANN controller developed has been compared with two previously studied methods of using conventional PI based speed controller and the PI-PSO based controller. From the simulation results, it has been shown that the proposed method is much better than the conventional PI based method and also relatively comparable to the results of PI-PSO method. This shows that it is alternative way of using the intelligent controller of ANN to replace the conventional method of PI control system.
Molecular chaperones as modulators of polyglutamine protein aggregation and toxicity

The formation of insoluble protein aggregates in neurons is a hallmark of neurodegenerative diseases caused by proteins with expanded polyglutamine (polyQ) repeats. However, the mechanistic relationship between polyQ aggregation and its toxic effects on neurons remains unclear. Two main hypotheses have been put forward for how polyQ expansions may cause cellular dysfunction. In one model neurotoxicity results from the ability of polyQ-expanded proteins to recruit other important cellular proteins with polyQ stretches into the aggregates. In the other model, aggregating polyQ proteins partially inhibit the ubiquitin–proteasome system for protein degradation. These two mechanisms are not exclusive but may act in combination. In general, protein misfolding and aggregation are prevented by the machinery of molecular chaperones. Some chaperones such as the members of the Hsp70 family also modulate polyQ aggregation and suppress its toxicity. These recent findings suggest that an imbalance between the neuronal chaperone capacity and the production of potentially dangerous polyQ proteins may trigger the onset of polyQ disease.
A Mathematical Model of Mitotic Exit in Budding Yeast: The Role of Polo Kinase

Cell cycle progression in eukaryotes is regulated by periodic activation and inactivation of a family of cyclin–dependent kinases (Cdk's). Entry into mitosis requires phosphorylation of many proteins targeted by mitotic Cdk, and exit from mitosis requires proteolysis of mitotic cyclins and dephosphorylation of their targeted proteins. Mitotic exit in budding yeast is known to involve the interplay of mitotic kinases (Cdk and Polo kinases) and phosphatases (Cdc55/PP2A and Cdc14), as well as the action of the anaphase promoting complex (APC) in degrading specific proteins in anaphase and telophase. To understand the intricacies of this mechanism, we propose a mathematical model for the molecular events during mitotic exit in budding yeast. The model captures the dynamics of this network in wild-type yeast cells and 110 mutant strains. The model clarifies the roles of Polo-like kinase (Cdc5) in the Cdc14 early anaphase release pathway and in the G-protein regulated mitotic exit network.
Blind Spectrum Selection in a Decentralized Cognitive Radio Networks with Heterogeneous Applications

In this paper, we consider a cognitive radio network in which the sensing ability of cognitive radio is limited and the channel statistics are not known as a priori information in the opportunistic spectrum access(OSA) framework. It is a special challenge to design a joint spectrum sensing and access strategy for secondary users with diverse service requirements of heterogeneous applications, i.e. the real-time applications and best-effort applications. We formulate the spectrum decision problem as a decentralized multi-armed bandit problem and propose slot structures for cognitive radio network to cope with collisions between heterogeneous applications. The proposed scheme is proved achieving logarithmic regrets in time asymptotically and simulation results show that each user orthogonalizes into their rank-optimal channels according to their pre-allocated priorities, which indicates efficient spectrum utilization while satisfying service requirements.
Transcapillary migration of heavy water and thiocyanate ion in the pulmonary circulation of normal subjects and patients with congestive heart failure.

During recent years numerous investigations have been concerned with the rates of transfer or exchange of various substances across capillary beds (1-6). These studies, by analyzing curves of disappearance over several minutes from arterial plasma of intravenously injected tracer substances, have provided some information relative to all capillary beds combined. However, this type of experiment has not permitted a close analysis of the behavior of a substance during its first passage through a single organ capillary bed. Recently developed techniques (7-9) now permit the clinical investigator to examine the phenomena of transcapillary exchange of water and other diffusible substances in local vascular areas. This study was undertaken in an attempt to determine in vivo the diffusion characteristics of the pulmonary capillary bed in man with regard to deuterium oxide and an electrolyte, thiocyanate ion. Seven normal subjects and seven patients with pulmonary congestion due to heart failure were studied. The resulting data relating to the pulmonary capillaries were then compared to those previously obtained using similar tracer substances in the capillaries of the human forearm (7).
A planar positioning-free magnetically-coupled resonant wireless power transfer

A novel magnetically-coupled resonant wireless power transfer (MCR-WPT) system using an array of printed spiral coil (PSC) resonators is presented to expand the receiving area. The resonator array is excited with a single planar driving loop to yield uniform magnetic field distribution at the receiver plane. First, the performance of a conventional transmitter coil array consisting of one transmitting resonator and multiple repeaters without frequency tracking is investigated. Then the performance of the proposed PSC resonator array with novel feed strategy is demonstrated. The results show the proposed MCR-WPT array system is able to provide consistent transfer efficiency when the receiver is axially misaligned with the transmitter. The measurement results are compared with the conventional planar MCR-WPT array and reveal that that with the proposed design, the transfer efficiency of the planar MCR-WPT system can be increased from 2.1% to 65.8% in the misalignment region.
RED, WHITE, AND BLUE EGGS AS MODELS OF PORPHYRIN AND HEME METABOLISM *

A fascinating discussion of “The Races of Domestic Fowl” appeared almost one-half century ago in the National Geographic magazine. Among the numerous paintings shown are those of three breeds of hens that we have included in our studies because they illustrate the diversity of shell pigmentation: ( 1 ) the Rhode Island Red hen, which lays red-brown eggs; (2) the White Leghorn hen (called “the greatest egg-laying machine in the poultry world”), which lays white eggs; and (3) the less well known Araucana hen, which lays eggs that range in color from deep blue t o light green. $ It is clear that color of egg shells is determined by a mixture of pigments. In an extensive study undertaken about 100 years ago, Sorby3 extracted shell
African media breaks ‘culture of silence’

When on 18 March this year the Daily Nation, one of Africa’s biggest and most successful independent newspapers, celebrated its 50th anniversary, Charles Onyango Obbo, a columnist for the Nairobi, Kenya, paper, wrote, “It has mostly been hell on earth for the African media for most of these 50 years. In fact the freest period for the African media generally has been the 15-year period between 1990 and 2005. ”
Successful Treatment of Dissemination of Hepatocellular Carcinoma to the Pleura and Diaphragm after Percutaneous Liver Biopsy

Background/Aim: Treatment for dissemination of hepatocellular carcinoma to the pleura and diaphragm following percutaneous needle biopsy has not been established. Methods: The case of a 57-year-old man who underwent percutaneous needle biopsy for liver tumor is presented. Results: Ten months after resection of the tumor (moderately differentiated hepatocellular carcinoma), masses in the right pleural cavity and on the diaphragm were detected by computed tomography. Resections of the masses with surrounding tissue and the diaphragm and wedge resection of the right lung were performed. A wide range of the pleura and the diaphragm was coagulated with an argon beam coagulator. The patient is in good health without recurrence 4 years after the operation. Conclusion: Aggressive surgical treatment should be considered for patients with dissemination of hepatocellular carcinoma by needle biopsy when the lesions are limited.
Real Time LP Decoding of LDPC Codes for High Correction Performance Applications

The alternate direction method of multipliers is a recent linear programming error correcting approach which improves the decoding performance of LDPC codes compared with the best BP decoding techniques. In this letter, an efficient implementation of the ADMM LP decoding algorithm on a multicore architecture is presented. Its throughput performance level is about one order of magnitude higher than related works on the same multicore target. The proposed decoder's throughput reaches up to 100 Mb/s which makes it viable for real time applications with tough error correction requirements.

The specific purpose of the study was to measure the accuracy with which individuals can perform positioning reactions in the absence of visual corrective cues. As used here, the term positioning reaction refers to a unitary movement of an articulate member of the body from a position of rest to another position in space.
Determinants of m-commerce adoption in Indonesia : a neural network approach

The promising number of smartphone users in Indonesia progressively drives the mobile commerce (mcommerce) development. Mobile commerce in this study presents an expanded of Unified Theory of Acceptance and Use of Technology (UTAUT) to examine key factors that affect the advanced usage of mcommerce among Indonesian smartphone users. The expanded model incorporates additional factors such as perceived risk, perceived value, and perceived enjoyment. Data was collected from 200 Indonesian users through online survey and distributed into several cities. Two nonparametric methods were used in this study to predict m-commerce adoption: principal component analysis (PCA) and artificial neural network (ANN). PCA was used to perform feature extraction in the first step while the neural networks were used to predict m-commerce adoption. The study reveals benefits from the combination of the PCA and neural network and provides some ideas for further research.
Screening for colorectal cancer: U.S. Preventive Services Task Force recommendation statement.

DESCRIPTION Update of the 2002 U.S. Preventive Services Task Force (USPSTF) recommendation statement on screening for colorectal cancer. METHODS To update its recommendation, the USPSTF commissioned 2 studies: 1) a targeted systematic evidence review on 4 selected questions relating to test characteristics and benefits and harms of screening technologies, and 2) a decision analytic modeling analysis using population modeling techniques to compare the expected health outcomes and resource requirements of available screening modalities when used in a programmatic way over time. RECOMMENDATIONS The USPSTF recommends screening for colorectal cancer using fecal occult blood testing, sigmoidoscopy, or colonoscopy in adults, beginning at age 50 years and continuing until age 75 years. The risks and benefits of these screening methods vary. (A recommendation). The USPSTF recommends against routine screening for colorectal cancer in adults 76 to 85 years of age. There may be considerations that support colorectal cancer screening in an individual patient. (C recommendation). The USPSTF recommends against screening for colorectal cancer in adults older than age 85 years. (D recommendation). The USPSTF concludes that the evidence is insufficient to assess the benefits and harms of computed tomographic colonography and fecal DNA testing as screening modalities for colorectal cancer. (I statement).
Addressing Knowledge Gaps in Adolescent Nutrition: Toward Advancing Public Health and Sustainable Development

Adolescence marks a critical period of growth in the life course. Malnutrition among adolescents includes suboptimal dietary intake of macronutrients and micronutrients as well as overweight and obesity linked to poor dietary quality. We discuss adolescent nutrition and outline 3 knowledge gaps toward advancing adolescent health. First, micronutrient and macronutrient supplements have significant potential to improve nutritional status, but information on the most effective implementation strategies is lacking. Second, food system interventions offer a promising avenue to improve access to healthy foods, and school settings may be an important entry point for improving diets. Third, nutrition programs should be combined with delayed pregnancy interventions for greatest impact given the adverse effects of early pregnancy on maternal and infant health and nutrition outcomes. Evidence-based solutions for adolescent nutritional supplementation, food system and dietary intake interventions, and integration with sexual and reproductive health strategies present crucial opportunities for improving adolescent health and well-being.
Properties of the spectra of asymmetric molecules: matrix evaluation in bases of spherical harmonics and common generating function,

Se sabe que la ecuacion de Schrodinger para los estados rotacionales de moleculas asimetricas es separable en coordenadas esferoconales e integrable en terminos de funciones de Lame. Sin embargo, la evaluacion numerica de las ultimas no se ha desarrollado eficientemente, limitando por lo tanto la aplicacion practica de tales soluciones. En este articulo, la evaluacion matricial de los estados rotacionales se formula e implementa numericamente para cualquier molecula asimetrica, usando la base familiar de armonicos esfericos. La matriz del Hamiltoniano - en un sistema de referencia fijo en la molecula y orientado a lo largo de los ejes principales - se construye en la base escogida y se muestra que se separa en bloques de ( l + 1) × ( l + 1) y l × l, para cada valor del numero cuantico de momento angular l. La diagonalizacion de los bloques sucesivos conduce a valores precisos de las eigenenergias y los eigenvalores para todos los valores de los parametros de asimetria. Tambien se establece la conexion entre estos estados rotacionales y su representacion en terminos de funciones de Lame, identificando al mismo tiempo una funcion generadora comun para armonicos esfericos y armonicos esferoconales.
PATHWAYS OF OXIDATION OF REDUCED NICOTINAMIDE NUCLEOTIDES IN THE CENTRAL NERVOUS SYSTEM OF MARINE ANIMALS

ALTHOUGH a considerable amount of information on the enzymic systems of oxidation of NADH and NADPH in mammalian brain has accumulated in recent years (GIUDITTA, 1964), few data are available for the central nervous system of less developed animals. It is known that the oxidation of NADH and NADPH in the cerebral tissue of mammals is catalysed by the following systems which have been identified and described chiefly in rat and ox brain : (1) a multicomponent system in mitochondria which catalyses the oxidation of NADH by oxygen and is inhibited by antimycin A and amytal. It is well known that this oxidation pathway is linked to phosphorylation processes; (2) a microsomal system presumably composed of a specific flavoprotein and of cytochrome b, which oxidizes NADH in presence of several electron acceptors including cytochrome c ; (3) a microsomal flavoprotein which catalyses the oxidation of NADPH by several electron acceptors including cytochrome c. The NADHand NADPHXytochrome c reductase activities of these last two systems are not inhibited by antimycin A and amytal; (4) a soluble NAD(P)H dehydrogenase which oxidizes both NADH and NADPH in presence of electron acceptors including vitamin K3 (menadione) and K1 and is strongly inhibited by low concentrations of dicumarol; (5) a similar NAD(P)H dehydrogenase bound to the particulate fraction of the homogenate ; (6) an NADH-ferricyanide reductase relatively insensitive to dicumarol and (7) an NADPH-glutathione reductase. The specific biological role of each of these pathways is unknown, with the exception of the mitochondria1 NADH oxidase system which is linked to the process of oxidative phosphorylation. It was hoped that an investigation of the pattern of oxidation of reduced nicotinamide nucleotides in the CNS of marine animals, besides providing data of value for comparative neurochemistry, might reveal the presence of relatively simple patterns of oxidation compared with those of mammals. The high degree of organization and complexity of mammalian brain adds to the difficulty of understanding the role of these enzymes in the nervous tissue. A simpler pattern of NADH and NADPH oxidation might provide some clue toward this aim. To this end the enzymic systems of oxidation of reduced nicotinamide nucleotides were measured in homogenates obtained from the CNS of several species of marine
An unmixing framework to improve class accuracies using detected high importance local regions

Image Classification techniques are aimed at improving the class accuracies which are affected by the occurrence of mixed pixels in the remotely sensed data. Improving the labeling accuracies for the mixed pixels regions will increase the global class accuracies. Spectral unmixing has been used to decompose the mixed pixel regions into its constituent endmembers, and a corresponding fractional abundance for each endmember. The unmixing approaches are approximated based on spectral behavior, but ignore the spatial neighborhood. The data values at the pixel along with its spatial neighborhood are good indicators of the image characteristics including atmospheric conditions and need to be considered. In the current research, we propose a spatio-spectral framework that improves the classification accuracy and demonstrates its utility by improving the labels of the detected mixed regions for MODIS data and validated with AWIFS (APLULC 2005) derived land cover dataset.
Detecting Network Attack Vectors On SCADA Specific Network Operating On Modbus TCP/IP Protocol

___ Abstract —Supervisory Control and Data Acquisition (SCADA) systems, a part of Industrial Control Systems (ICS) are widely used for automation and control in many industry sectors, chemical plants, electric power grids, oil and gas plants etc. Traditionally these (i.e. SCADA) systems were operated in standalone manner, typically housed within the industries, chemical plants etc. However, due to the expansion of business and the need to centrally monitor and control these systems, they are now being connected to a completely alien world, the world of Internet. Naturally, as these systems are now being connected to the internet, they are prone to plethora of attacks prevailing on internet. Much research is being carried out to detect and mitigate the effect of network attacks on SCADA specific networks but, one must also consider the significance of attacks done inside the secured periphery of the controlled systems, called as “insider attacks”. One can imagine the consequences if such critical infrastructure are tempered or illegally gained control of. If someone tries to gain control over some of the Servers or hacks into someone`s system through internet then the loss would be either financial and/or business function. However, when SCADA systems are compromised then the loss would not just be financial and/
