SuperFlow: A Reliable, Controllable and Scalable Architecture for Large-Scale Enterprise Networks

Enterprise networks have become increasingly important with the rising number of users accessing their services, which consequently brings challenges in various aspects. Though Open Flow, the promising scheme for enterprise network control, can provide fine-grained and flow-level control in networks, yet it still has a few undesirable designs in security, scalability and performance. Inspired by many excellent Open Flow-included studies, we in this paper, propose Super Flow, a reliable, controlable and scalable architecture for large-scale enterprise networks. It not only inherits the merits of Open Flow, but also overcomes Open Flow's limitations by introducing many novel features, including the trustiness between hosts and users based on the compulsory authentication mechanisms, the flexible flow controling upon the well-organized control-rule designing, the scalable architecture considerations in both controller load-balancing and management scales. The prototype experiments also prove that Super Flow possesses these features with desirable performance.
FLENG : THE FLEXIBLE INFERENCE ENGINE

Previous efforts in implementation of systems with Meta-knowledge (e.g. TEIRESIAS and MOLGEN) have been limited to some degree of hard-coded features. In this paper we introduce a Flexible Engine (FlEng) as an experimental inference engine which keeps its control strategy with its object knowledge both together. The inference engine (FlEng) is a small kernel using the complex inference mechanisms stored as part of knowledge base. Open definitions let the knowledge engineer (re)write a control strategy. The architecture of FlEng has been described in this paper. It has been shown that the (1) automatic evaluation of control strategies, (2) processing the uncertainty of control strategies and also (3) learning new inference methods could be performed by FlEng.
Depressive Mood and Fatigue in Iranian Patients With Spinal Cord Injury and Spared Walking Ability

SCI in all cognitive (P < 0.0001, r = 0.81), physical (P = 0.001, r = 0.58) and psychosocial (P = 0.001, r = 0.57) domains. Based on the previously measured cutoff point in MFIS-SCI, 53.3% of our patients were fatigued. Patients with cervical level injury had significantly higher fatigue impacts (P: 0.036). Conclusions: This study showed that a majority of patients with traumatic SCI who had spared ability of walking were fatigued, while depressive mood was less frequent among these patients. Neuropathic pain was not a determinant for fatigue and depression. Although the extent of physical activity was relatively similar among these patients, those with higher injury levels had higher fatigue impacts.
A mathematical programming based characterization of Nash equilibria of some constrained stochastic games

We consider two classes of constrained finite state-action stochas- tic games. First, we consider a two player nonzero sum single controller con- strained stochastic game with both average and discounted cost criterion. We consider the same type of constraints as in (1), i.e., player 1 has subscrip- tion based constraints and player 2, who controls the transition probabilities, has realization based constraints which can also depend on the strategies of player 1. Next, we consider a N-player nonzero sum constrained stochastic game with independent state processes where each player has average cost cri- terion as discussed in (2). We show that the stationary Nash equilibria of both classes of constrained games, which exists under strong Slater and irreducibil- ity conditions (3), (2), has one to one correspondence with global minima of certain mathematical programs. In the single controller game if the constraints of player 2 do not depend on the strategies of the player 1, then the mathe- matical program reduces to the non-convex quadratic program. In two player independent state processes stochastic game if the constraints of a player do not depend on the strategies of another player, then the mathematical pro- gram reduces to a non-convex quadratic program. Computational algorithms for finding global minima of non-convex quadratic program exist (4), (5) and hence, one can compute Nash equilibria of these constrained stochastic games. Our results generalize some existing results for zero sum games (1), (6), (7). ⋆ A portion of Section 3 (two player case) has been presented in the 8th International
An architecture for a reconfigurable charge summation based ADC

Presented in this paper is a low power, area efficient reconfigurable analog-to-digital (ADC) converter, utilising a charge-summation technique with a switched-capacitor implementation. Using a non-inverting switched-capacitor integrator a staircase ramp is produced using switching capacitors and a fixed reference voltage, as opposed to a linear ramp. The advantage of the charge summation technique is the reduction in power usage as the charging time of the capacitors is small so for most of the sample period the circuit is quiescent. The paper presents the use of this architecture as a reconfigurable ADC for use in a reconfigurable radio.
The Relationship between Trait Emotional Intelligence and Self-efficacy among Iranian EFL Teachers

The current study examined the relationship between Iranian EFL teachers’ trait EI (trait EI) and Self-efficacy. To this end, 336 teachers were asked to complete “Trait Emotional Intelligence Questionnaire–Short Form (TEIQue–SF)” (Petrides and Furnham, 2006) and “Teacher Sense of Efficacy Scale (TSES)” (Tschannen-Moran & Woolfolk Hoy, 2001). Pearson product-moment correlation showed a significant relationship between trait EI and self-efficacy. Trait EI subconstructs also showed significant relationship with Self-efficacy subconstructs as well as total self-efficacy. To investigate which subconstructs of trait emotional intelligence might have more predictive power in predicting teacher’s self-efficacy, regression analysis was run. Results revealed all subconstructs of trait EI to be moderate predictors of Self-efficacy. In addition, the ANOVA were employed to investigate the influence of teachers’ age, gender, and years of teaching experience on EI and Self-efficacy. Results showed teachers with more years of teaching experience to have achieved higher levels in both trait EI and self-efficacy. However no effect of EFL teachers’ age, gender and their interactions on teachers’ trait EI and Self-efficacy were observed.
DOMER: A Wizard of Oz interface for using interactive robots to scaffold social skills for children with Autism Spectrum Disorders

This report describes the development of a prototypical Wizard of Oz, graphical user interface to wirelessly control a small, humanoid robot (Aldebaran Nao) during a therapy session for children with Autism Spectrum Disorders (ASD). The Dynamically Operated Manually Executed Robot interface (DOMER) enables an operator to initiate pre-developed behavior sequences for the robot as well as access the text-to-speech capability of the robot in real-time interactions between children with ASD and their therapist. Preliminary results from a pilot study suggest that the interface enables the operator to control the robot with sufficient fidelity such that the robot can provide positive feedback, practice social dialogue, and play the game, “Simon Says” in a convincing and engaging manner.
Inverse observation model and multiple hypothesis tracking for indoor mobile robots

This paper presents a complete robot perception system of moving point detection and target tracking for robustly following target human in an unknown indoor dynamic environment. To detect moving points under grid-based formulation, a modified inverse observation model is proposed to overcome several frequently happened detection limitations. Next, related human-extraction techniques are proposed to filter out less possible clusters for detecting potential human target from these moving points. Finally, the multiple hypothesis tracking algorithm is implemented to deal with the data association problem for enhancing the reliability and robustness of the human tracking when measurements are noisy. Related experiments have been performed to evaluate the effectiveness of the proposed algorithm framework.
Has it become increasingly expensive to follow a nutritious diet? Insights from a new price index for nutritious diets in Sweden 1980–2012

Background Health-related illnesses such as obesity and diabetes continue to increase, particularly in groups of low socioeconomic status. The increasing cost of nutritious food has been suggested as an explanation. Objective To construct a price index describing the cost of a diet adhering to nutritional recommendations for a rational and knowledgeable consumer and, furthermore, to investigate which nutrients have become more expensive to obtain over time. Methods Linear programming and goal programming were used to calculate two optimal and nutritious diets for each year in the interval under different assumptions. The first model describes the rational choice of a cost-minimizing consumer; the second, the choice of a consumer trying to deviate as little as possible from average consumption. Shadow price analysis was used to investigate how nutrients contribute to the diet cost. Results The cost of a diet adhering to nutritional recommendations has not increased more than general food prices in Sweden between 1980 and 2012. However, following nutrient recommendations increases the diet cost even for a rational consumer, particularly for vitamin D, iron, and selenium. The cost of adhering to the vitamin D recommendation has increased faster than the general food prices. Conclusions Not adhering to recommendations (especially those for vitamin D) offers an opportunity for consumers to lower the diet cost. However, the cost of nutritious diets has not increased more than the cost of food in general between 1980 and 2012 in Sweden.
Two-Tier Storage DBMS for High-Performance Query Processing

This paper describes the design and implementation of a two-tier DBMS for handling massive data and providing faster response time. In the present day, the main requirements of DBMS are figured out using two aspects. The first is handling large amounts of data. And the second is providing fast response time. But in fact, Traditional DBMS cannot fulfill both the requirements. The disk-oriented DBMS can handle massive data but the response time is relatively slower than the memory-resident DBMS. On the other hand, the memory-resident DBMS can provide fast response time but they have original restrictions of database size. In this paper, to meet the requirements of handling large volumes of data and providing fast response time, a two-tier DBMS is proposed. The cold-data which does not require fast response times are managed by disk storage manager, and the hot-data which require fast response time among the large volumes of data are handled by memory storage manager as snapshots. As a result, the proposed system performs significantly better than disk- oriented DBMS with an added advantage to manage massive data at the same time.
In vitro reconstitution of the human RISC-loading complex

Targeted gene silencing by RNAi requires the RNA-induced silencing complex (RISC), whose core component is the protein Argonaute (Ago) bound to a microRNA (miRNA) or an siRNA. In humans, Ago2 is loaded with miRNAs by the action of a specialized assembly called the RISC-loading complex (RLC), comprising the proteins Ago2, Dicer, and TRBP. Here we show that the human RLC assembles spontaneously in vitro from purified components. No cofactors or chaperones are required for the complex to form. The reconstituted RLC, containing one copy of each protein, has the dicing, slicing, guide-strand selection, and Ago2-loading activities observed for the endogenous RLC. Furthermore, once Ago2 is loaded with an miRNA, it tends to dissociate from the rest of the complex. These results lay the groundwork for future structural and functional dissection of RISC loading in humans.
Pure sensory Guillain-Barré syndrome: A case report and review of the literature

Sensory Guillain-Barré syndrome (GBS) is an acute demyelinating neuropathy that presents clinically with involvement of the sensory peripheral nerve only. To date, <10 cases of pure sensory GBS have been reported; thus, the clinical and pathological features of sensory variant GBS are yet to be well characterized. The current study reports the case of a 43-year-old female that presented with acute, symmetric and monophasic sensory neuropathy, without motor weakness. Patient history, clinical examination, routine nerve conduction studies and sural nerve biopsy were reviewed. All the observations were consistent with a diagnosis of pure sensory GBS. In particular, the pathological features of the sural nerve biopsy revealed that the form of regenerated nerve fibers have complete structure of myelinated nerve fascicles, and these myelinated nerve fibers are thicker than other parts of the biopsy. The patient received small-dose (20 mg/day) prednisone initially, but without any benefit. Satisfactory improvements were observed with one course of intravenous immunoglobulin.
MULTIRESOLUTION ANALYSIS OF CURVES AND SURFACES FOR USE IN TERRAIN REPRESENTATION

In the domain of real-time simulation, terrain has long been represented as polygons. This is mainly due to the fact that image generators contain special purpose hardware that quickly processes polygons located within a static database. However, difficulties in supporting terrain issues such as level of detail, resolution, correlation, dynamics and networking have stretched the capabilities of polygons to the limit. Recently, there has been increased research into the use of mathematical surfaces as a means for representing terrain. The intent of these representations is to reduce problems relative to the five terrain issues listed above. This thesis continues that body of work by experimenting with an object-oriented hierarchy of spline wavelets and multiresolution analysis to produce a method for representing a surface-based terrain at multiple resolutions. This new method allows greater control of level of detail and multiple resolutions at little added cost. It is expected that this added power will decrease correlation errors between terrain databases, allow for easier dynamic changes to the terrain, and lower networking costs. iii Acknowledgments First, I would like to thank my advisor, Dr. Charles E. Hughes, for his encouragement and insight as I performed this research. He showed great interest in the topic of wavelets and multiresolution analysis which made the research that much more exciting.

A Self-ORganizing Trust Model Based on HP2P

Peer-to-Peer(P2P) reputation systems are essential to evaluate the trustworthiness of the nodes in a P2P system. This paper presents a distributed algorithm HP2PSORT based on SORT that enables a node to estimate the trustworthiness of other nodes based on the past interactions and recommendations. In an HP2P network, by using the filtering mechanism, the calculation method of the service trust and the dynamic calculation of the threshold value, we show that HP2PSORT outperforms SORT.
A monolithic 1.85GHz 2-stage sige power amplifier with envelope tracking for improved linear power and efficiency

In this paper, a monolithic 2-stage differential power amplifier (PA) is designed and fabricated in the 0.35 μm IBM 5PAe SiGe BiCMOS technology where the through-wafer-vias (TWVs) are available. A cascode topology is adopted to relieve the voltage stress for the power stage transistors. All components are integrated on-chip for the PA except the input/output baluns. The envelope tracking (ET) technique is applied to this 2-stage PA to enhance the PAE and linearity for high power-to-average-ratio (PAR) Long-Term-Evolution (LTE) signals. The ET-based PA system achieves a linear output power of 20.4 dBm with a gain of 30.5 dB and an overall system PAE of 22%, using an LTE 16QAM 5 MHz signal with ~7.5 dB PAR at 1.85 GHz. Compared to the 2-stage PA operating with fixed voltage supplies, the ET-based PA system improves the linear output power by 3.2 dB and its system PAE by over 10%.
"Double hit" lymphoma or secondary MYC translocation lymphoma?

Chromosomal translocations that juxtapose different genes required for proliferation and differentiation are frequently associated with hematologic neoplasms. A term "double hit" lymphoma refers to a group of mature B-cell malignancies that harbor MYC rearrangement accompanied with another translocation commonly found in lymphomas (i.e. IGH/BCL2). A complex karyotype with multiple abnormalities and very aggressive course of disease are additional characteristics of this group. The response to currently available treatment regimens is unsatisfying, thus reported overall survival of these patients is usually very short. Today, the precise mechanisms of "double hit" lymphoma development are still unclear, although several possible pathways have been proposed in the literature. Similar oncogenic chain of events was also observed in another common hematological malignant neoplasm – multiple myeloma. MYC translocation as a secondary pathogenic phenomenon has been demonstrated in multiple myeloma, as well as complex cytogenetics and very aggressive course of the disease. Therefore, a secondary translocation involving MYC gene might be a potential marker of aggressive neoplasms emerging from different cells of origin, and united under the umbrella of "MYC-plus" malignancies. That concept might, in the future, result in a novel therapy, targeting this distinct, but not unique cytogenetic aberration.
Direct and Indirect Impacts of Urbanization on Wetland Quality Wetlands & Watersheds

Executive Summary This article synthesizes more than 100 scientific studies on the direct and indirect impacts of urbanization on wetlands and the key role wetlands play in watershed quality. Some of the major findings include: • Wetlands provide important ecological services that contribute to watershed functions, most notably in pollutant removal, flood attenuation, groundwater recharge and discharge, shoreline protection, and wildlife habitat. The benefit of wetland ecological services generally increases as total wetland cover increases in a watershed. Numerous researchers have quantified the economic benefits provided by wetlands in a watershed. When wetlands are lost or degraded by land development, these services must often be replaced by costly water treatment and flood control infrastructure. Given the many watershed services wetlands provide, wetland conservation and restoration should be an integral part of a comprehensive local watershed management strategy. • Although the national rate of wetland loss has dropped sharply in recent years, the goal of no net loss in wetland quality remains elusive. Development in urban and rural areas now is the cause of more than 60% of national wetland loss. Several national assessments have noted deficiencies in current federal and state regulatory programs that allow direct and indirect impacts to wetlands that reduce their function and quality to continue. These regulatory gaps can best be closed by increased local management and regulation of wetlands. • More than 50 of the studies reviewed document indirect impacts to wetlands caused by land alteration in the contributing drainage area to wetlands. Upland development increases stormwater to wetlands, and downstream crossings create flow constrictions. Together these changes lead to increased ponding, greater water level fluctuation and/or hydrologic drought in urban wetlands. In addition, urban wetlands receive greater inputs of sediment, nutrients, chlorides, and other pollutants; concentrations in urban stormwater are typically one to two orders of magnitude greater than predevelopment conditions (Schueler, 1987). • Numerous studies describe how urban wetlands respond to these stressors. Although the precise response depends on the sensitivity and landscape position of the wetland, the Article 1: Direct and Indirect Impacts of Urbanization on Wetland Quality ii Wetlands & Watersheds Article Series general trend is a sharp decline in the diversity of the native plant and animal community and an increase in invasive plant species that can tolerate stressed conditions. Research has shown that degraded urban wetlands lose many of their important watershed functions. The indirect impact of upland development …
