Bandwidth Estimation Based on MACD for DASH (2016)

Nowadays, Dynamic Adaptive Streaming over HTTP (DASH) has become very popular in streaming multimedia contents. In order to offer better user experience and cope with dynamically varying network conditions, a big challenge is to estimate precisely next segment bandwidth, which is a significant premise in determining next multimedia bitrate, especially when multiple clients share the same bottleneck link. In this paper, we address an innovative mechanism to estimate the bandwidth based on MACD indicator and its two thresholds. Then, with the estimated bandwidth, we use GA to determine the next multimedia bitrate. Our simulation demonstrates that our proposed approach outperforms other existing schemes.
Human studies with probiotics and prebiotics: clinical implications (2002)

Probiotic agents have been shown to have significant clinical beneficial effects in the prevention and management of gastrointestinal and non-gastrointestinal conditions. These observations have led to work demonstrating that an important mechanism of these agents is their close interaction with the gut associated lymphoid tissue (GALT) and suggested immunomodulatory effects on systemic immune response. Studies on the possibility that prebiotic agents might directly or indirectly induce similar immunomodulation have only recently begun. The preliminary findings of several recent human clinical trials reviewed in this article indicate that prebiotics may indeed prove to be a clinically beneficial dietary supplement, in the context of novel nutritional strategies for the management of gastrointestinal and systemic conditions.
Decoding Smart Contracts: Technology, Legitimacy, & Legislative Uniformity (2019)

Blockchain technology is increasingly permeating the everyday lives of countless people. Applications of the cutting-edge technology range from secured banking to tracking mortgage titles. A particular blockchain technology, dubbed “smart contracts,” has the potential to revolutionize how individuals and companies securely contract with each other. Smart contracts, however, are not widely employed, mainly because potential users are uncertain of their enforceability as contracts under existing state contract laws. Similar skepticism slowed the acceptance of electronic signatures in the late 1990s, but was resolved ultimately through a model uniform act recognizing electronic signatures’ effectiveness across interstate borders. This Note proposes a similar solution for smart contracts based on a review of current state legislative developments and existing laws regulating blockchain technology.
vCUDA: GPU accelerated high performance computing in virtual machines (2009)

This paper describes vCUDA, a GPGPU (General Purpose Graphics Processing Unit) computing solution for virtual machines. vCUDA allows applications executing within virtual machines (VMs) to leverage hardware acceleration, which can be beneficial to the performance of a class of high performance computing (HPC) applications. The key idea in our design is: API call interception and redirection. With API interception and redirection, applications in VMs can access graphics hardware device and achieve high performance computing in a transparent way. We carry out detailed analysis on the performance and overhead of our framework. Our evaluation shows that GPU acceleration for HPC applications in VMs is feasible and competitive with those running in a native, non-virtualized environment. Furthermore, our evaluation also identifies the main cause of overhead in our current framework, and we give some suggestions for future improvement.
Restricted utilization of germ‐line V<sub>H</sub>3 genes and short diverse third complementarity‐determining regions (CDR3) in human fetal B lymphocyte immunoglobulin heavy chain rearrangements (1992)

Twenty-one independent immunoglobulin heavy chain VH3DJH rearrangements were cloned and sequenced from livers of human fetuses at 7, 13 and 18 weeks of gestation. The VH elements expressed were not somatically mutated. Eight out of the estimated 30 VH3 elements were utilized with a preference for five of them. One of these VH3 sequences, designated FL13-28, represented a thus-far unknown VH3 gene segment. From the six functional JH elements the JH3 and JH4 segments were utilized preferentially and from the estimated 30 D segments the DQ52 element and the Dxp family were found to rearrange frequently. D elements were utilized both in normal and inverted orientation, as single copies or in D to D fusions. Addition of N nucleotides, removal of nucleotides from the coding sequences and utilization of DIR elements (D genes with irregular recombination signals) further expanded the third complementarity-determining region (CDR3) diversity. One fourth of the fetal CDR3 regions lacked N regions. Due to utilization of DQ52, the relative absence of N regions and extensive exonuclease activity operating on the D elements, the fetal CDR3 regions were significantly shorter than those found in adult B lymphocytes.
Free-field reciprocity calibration of laboratory standard (LS) microphones using a time selective technique (2006)

Although the basic principle of reciprocity calibration of microphones in a free field is simple, the practical problems are complicated due to the low signal-to-noise ratio and the influence of cross talk and reflections from the surroundings. The influence of uncorrelated noise can be reduced by conventional narrow-band filtering and time averaging, while correlated signals like cross talk and reflections can be eliminated by using time-selective postprocessing techniques. The technique used at DPLA overcomes both these problems using a B&K Pulse analyzer in the SSR mode (steady state response) and an FFT-based time-selective technique. The complex electrical transfer impedance is measured in linear frequency steps from a few kHz to about three times the resonance frequency of the microphones. The missing values at low frequencies are estimated from a detailed knowledge of the pressure sensitivities. Next an inverse FFT is applied and a time window around the main signal is used to eliminate cross talk and reflections. Finally, the signal is transformed back to the frequency domain and the free field sensitivities calculated. The standard procedure at DPLA involves measurements at four distances and the repeatability of the calibrations over time is within ±0.03 dB up to about 1.5 times the resonance frequency of the microphones.

Las malformaciones urogenitales incluyen displasia medular renal, lobulacion del rinon fetal y sindrome de Prune-belly. La primera descripcion de este sindrome se debe a Beckwith (1963) y a Wiedemann (1969); quienes lo describen como un trastorno por sobrecrecimiento.
Anomalous Response Times of Input Synchronizers (1976)

This paper deals with an anomalous behavior of input synchronizers which results in the occurrence of random errors in asynchronously interfaced synchronous digital systems. The errors are caused by the undefined response time of a flip-flop as it recovers from its metastable state. To obtain their frequency, the timing diagram of the flip-flops has been analyzed and the probability distribution of the anomalous response times has been measured. As an example, maximum response time of SN74S74 is estimated on the basis of a set of statistical measurements. The measurement technique presented may be used for any type of input synchronizer. Two well-known methods of reducing failure probability for SN74S74 are evaluated. Two fundamental solutions of the metastable-state problem in the clocked systems are described.
Active modal control for smart structures (2001)

Of the multitude of control techniques available, modal control is a favourite amongst structural dynamicists because of its connection to design, intuition and testing. Here we review the state–of–the–art in modal control, point out its weaknesses and strengths and reveal its important connection to the emerging technology of smart structures. Modal control became a powerful tool in the early 1980s when applied in the arena of large flexible spacecraft. However, modal based methods then fell into disfavour as the problems of control spill–over (coupling to truncated modes and unmodelled dynamics) could not be prevented in structures with significant flexibility. Recently, however, modal control methods have reappeared in smart structure's applications because the ready availability of numerous sensors and actuators renders the control spill–over problem manageable. In addition, a number of advanced theories sorted out the spill–over problem. These issues are discussed here, complete with expository numerical examples and experimental verification that modal control, when used with smart structures, is an effective and simple solution to problems associated with control of flexible structures.
Radio emission from Jupiter observed by Ulysses before and after encounter (1993)

The polarization and the occurrence probability of the radio emission from Jupiter at 940 and 52 kHz are compared before and after encounter. It is found that, after encounter, the right-hand polarized Main Component of the broad-band kilometric emission (bKOM) is not present while the left-hand polarized Intermittent Component is considerably enhanced. Both the left- and the right-hand components of the hectometric emission (HOM) are essentially absent after encounter. These results, which are almost certainly erects of beaming, are compared with current theoretical ideas. While the 940 kHz observations can be reconciled fairly easily with HOM theory, the 52 kHz observations raise difficulties for the bKOM
Methodologische Grundpositionen der Lehre von den Internationalen Beziehungen. Eine retrospektive Skizze (1989)

Trotz ihrer im Vergleich zu anderen wissenschaftlichen Disziplinen relativ kurzen, erst zu Beginn der 20er Jahre unseres Jahrhunderts einsetzenden Geschichte (Naheres Meyers 1981: 15ff) ist die Entwicklung der Lehre von den Internationalen Beziehungen bis heute durch drei grundsatzliche Kontroversen geformt worden: durch die in den 30er und 40er Jahren gefuhrte Debatte zwischen Idealisten und Realisten (Grundpositionen bei Carr 1974), durch die die 50er und 60er Jahre in ihren Bann schlagende Auseinandersetzung zwischen Traditionalisten und Scientisten (Grundpositionen bei Knorr/Rosenau 1969) und schlieslich durch die anfangs der 70er Jahre anhebende, noch nicht beendete Diskussion zwischen „Globalisten“ und „Staatszentrikern“ (Grundpositionen bei Maghroori/Ramberg 1982). Wahrend die erste und die dritte dieser Kontroversen im wesentlichen inhaltlich gepragt sind, steht bei der zweiten die Entscheidung uber unterschiedliche methodische Zugriffe auf den Gegenstand „Internationale Beziehungen“ im Vordergrund. Genauer: im Kontext der ursprunglichen Idealismus-RealismusDebatte ebenso wie im Kontext der Auseinandersetzung zwischen „Globalisten“ (die, orientiert am Leitbegriff der Interdependenz, auf die Erforschung und theoretische Durchdringung der Phanomene Transnationaler Politik zielen) und „Staatszentrikern“ (die einen gleichsam revitalisierten, methodisch bewusteren Realismus vertreten) geht es primar um die Festlegung und Differenzierung eines „wissenschaftlichen Weltbildes“.
Ex vivo vessel wall thickness measurements of the human circle of Willis using 7T MRI (2018)

High-resolution MRI enables accurate measurement of vessel wall thickness in ex vivo CoW specimens. Vessel wall thickness measurements over the entire length of segments showed considerable variation both within and between arterial segments of patients.
Design and analysis of vertical axis thermoplastic composite wind turbine blade (2010)

There is growing interest in the use of thermoplastic composites for wind turbine blades. This paper presents preliminary work on the design, analysis and manufacture of a thermoplastic composite blade for a vertical axis wind turbine. The blade design featured a sandwich construction with commingled woven E-glass fibre/polypropylene thermoplastic composite skins and a polyethylene terephthalate (PET) foam core. A finite element modelling methodology has been developed for predicting the natural frequency and structural performance of the blade. For structural analysis, the skin was modelled with a composite damage model for which an inverse calibration procedure was developed. Vibration and static bending tests were conducted on a subscale prototype blade to validate the finite element models. A one-step vacuum moulding process was adopted to manufacture the prototype blade. The validated finite element models were then used to determine the natural frequency of the full sized blade and predict its performance under in-service aerodynamic loads. The results show that the thermoplastic composite blade design meets the desired structural requirements.
ElastiStore: Flexible Elastic Buffering for Virtual-Channel-Based Networks on Chip (2015)

As multicore systems transition to the many-core realm, the pressure on the interconnection network is substantially elevated. The network on chip (NoC) is expected to undertake the expanding demands of the ever-increasing numbers of processing elements, while its area/power footprint remains severely constrained. Hence, low-cost NoC designs that achieve high-throughput and low-latency operation are imperative for future scalability. While the buffers of the NoC routers are key enablers of high performance, they are also major consumers of area and power. In this paper, we extend elastic buffer (EB) architectures to support multiple virtual channels (VCs), and we derive ElastiStore, a novel lightweight EB architecture that minimizes buffering requirements without sacrificing performance. ElastiStore uses just one register per VC and a shared buffer sized large enough to merely cover the round-trip time that appears either on the NoC links or due to the internal pipeline of the NoC routers. The integration of the proposed EB scheme in the NoC router enables the design of efficient architectures, which offer the same performance as baseline VC-based routers, albeit at a significantly lower cost. Cycle-accurate network simulations including both synthetic traffic patterns and real application workloads running in a full-system simulation framework verify the efficacy of the proposed architecture. Moreover, the hardware implementation results using a 45-nm standard-cell library demonstrate ElastiStore's efficiency.
Syntax-Aware Multi-Sense Word Embeddings for Deep Compositional Models of Meaning (2015)

Deep compositional models of meaning acting on distributional representations of words in order to produce vectors of larger text constituents are evolving to a popular area of NLP research. We detail a compositional distributional framework based on a rich form of word embeddings that aims at facilitating the interactions between words in the context of a sentence. Embeddings and composition layers are jointly learned against a generic objective that enhances the vectors with syntactic information from the surrounding context. Furthermore, each word is associated with a number of senses, the most plausible of which is selected dynamically during the composition process. We evaluate the produced vectors qualitatively and quantitatively with positive results. At the sentence level, the effectiveness of the framework is demonstrated on the MSRPar task, for which we report results within the state-of-the-art range.
Field Efficacy Trials of Aerial Ultra-Low-Volume Application of Insecticides Against Caged Aedes aegypti in Mexico (2019)

We evaluated the efficacy of aerial ultra-low-volume (ULV) insecticide spraying in field bioassays with caged <i>Aedes aegypti</i> in May 2017 in Puerto Vallarta, Jalisco, Mexico. The insecticides tested included an organophosphate (Mosquitocida UNO ULV) and a neonicotinoid-pyrethroid combination (Cielo). Two <i>Ae. aegypti</i> populations were evaluated: a field pyrethroid-resistant local strain (Puerto Vallarta) and an insecticide-susceptible laboratory strain (New Orleans). Knockdown after 1 h by both products was ≥97.0%, and mortality after 24 h was ≥98% for the susceptible laboratory strain. Knockdown of the local Puerto Vallarta field strain by both products after 1 h was ≥96.5%; and mosquito mortality after 24 h was also very high (≥98%). Meteorological conditions during this evaluation were favorable for aerial mosquito control and represented conditions that typically occur during adulticide space spray applications. Temperature oscillated between 24°C and 26°C with winds between 6 and 10 km/h. The majority of droplets met the droplet distribution criteria required for the insecticides. The evaluation demonstrated an acceptable performance of both products for <i>Ae. aegypti</i> control when applied undiluted at a rate of 199.4 ml/ha and 73.07 ml/ha for Mosquitocida UNO ULV and Cielo, respectively. The volume median diameter (VMD) droplet size was characterized at 31.3 μm and 37.3 μm, respectively.

Comparative analysis of image filtering techniques (2015)

This paper is focused on various image filtering techniques. In the day to day scenario one clicks and share images at the spur of the moment on various social networking platforms. The image sharing has become an inevitable part of one's daily life. Even if one takes pictures using the modern Digital Single Lens Reflex (DSLR) cameras it requires a fair amount of effort to filter images. Image filtering is the technique of removing or reducing noise from a contaminated image. There are various image filters which have been successfully implemented on software tools. Each filter focuses on reducing a particular type of noise from the image. In this paper a comprehensive study has been presented with primary focus on various image filtering techniques.
Fast Online Computation of a Model Predictive Controller and Its Application to Fuel Economy–Oriented Adaptive Cruise Control (2014)

The recent progress of advanced vehicle control systems presents a great opportunity for the application of model predictive control (MPC) in the automotive industry. However, high computational complexity inherently associated with the receding horizon optimization must be addressed to achieve real-time implementation. This paper presents a generic scale reduction framework to reduce the online computational burden of MPC controllers. A lower dimensional MPC algorithm is formulated by combining an existing “move blocking ” strategy with a “constraint-set compression” strategy, which is proposed to further reduce the problem scale by partially relaxing inequality constraints in the prediction horizon. The closed-loop stability is guaranteed by adding terminal zero-state constraint. The tradeoff between control optimality and computational intensity is achieved by proper design of the blocking and compression matrices. The fast algorithm has been applied on intelligent vehicular longitudinal automation, implemented as a fuel economy-oriented adaptive cruise controller and experimentally evaluated by a series of real-time simulations and field tests. These results indicate that the proposed method significantly improves the computational speed while maintaining satisfactory control optimality without sacrificing the desired performance.
Supporting the negotiation life cycle (1998)

In our increasingly networked world, a capacity to negotiate will be a critical factor of success, or even survival.
Antigenic Properties of Subcellular Fractions from Canine Pancreas: Development of a Zymogen Membrane Specific Antibody (1975)

Immunization of rabbits with a membrane preparation from dog pancreas produced precipitating antibody against an antigen present in the pancreas of several mammals. This antigen appears to be organ-specific but not species-specific and is localized in the pancreatic zymogen granule membrane fraction. It is thought to represent glycoproteins of mol wt 70,000-90,000 as well as a smaller species of mol wt less than 10,000.
Your Glasses Know Your Diet: Dietary Monitoring Using Electromyography Sensors (2017)

Dietary monitoring can provide valuable information for disease diagnosis, body weight control, and dietary habit management, and thus it is welcomed by patients, dieters, and nutritionists. While various techniques have been used for dietary monitoring in clinical trials and user studies, they are not ready for daily use. Existing solutions either require tedious manual recording or may impede normal daily activities. In this paper, a pair of diet-aware glasses is designed. The key idea here is that when people wear glasses, the temples of the glasses are in touch with the lower part of the temporalis muscle, one of the mastication muscles. By integrating an electromyography (EMG) sensor into glasses, the glasses can measure the muscle activity of the temporalis to detect intake-related events. This paper instantiates the idea by building a prototype equipped with an EMG sensor, a microcontroller, SD shield/card and a Bluetooth radio. When working together with a smartphone, the glasses can provide detailed information on intake schedule, the number of chewing cycles and broad food category. Extensive experiments are conducted on seven subjects and the results show appealing prospects for our diet-aware glasses. The prototype achieves 96% accuracy for counting the number of chewing cycles and up to 90.8% accuracy for classifying five types of food.
