An Efficient Framework for Large Scale Multimedia Content Distribution in P2P Network: I2NC (2015)

Network coding (NC) makes content distribution more effective and easier in P2P content distribution network and reduces the burden of the original seeder. It generalizes traditional network routing by allowing the intermediate nodes to generate new coded packet by combining the received packets. The randomization introduced by network coding makes all packets equally important and resolves the problem of locating the rarest block. Further, it reduces traffic in the network. In this paper, we analyze the performance of traditional network coding in P2P content distribution network by using a mathematical model and it is proved that traffic reduction has not been fully achieved in P2P network using traditional network coding. It happens due to the redundant transmission of noninnovative information block among the peers in the network. Hence, we propose a new framework, called I2NC (intelligent-peer selection and incremental-network coding), to eliminate the unnecessary flooding of noninnovative coded packets and thereby to improve the performance of network coding in P2P content distribution further. A comparative study and analysis of the proposed system is made through various related implementations and the results show that 10-15% of traffic reduced and improved the average and maximum download time by reducing original seeder's workload.
Modulating Cell Cycle: Current Applications and Prospects for Future Drug Development (2002)

The cell cycle is a highly conserved and ordered set of events, culminating in cell growth and division. It is tightly controlled by many regulatory mechanisms that either permit or restrain its progression. The main families of regulatory proteins that play key roles in controlling cell cycle progression are the cyclins, the cyclin dependent kinases (Cdks), their substrate proteins, the Cdk inhibitors (CKI) and the tumor suppressor gene products, p53 and pRb. Many cell cycle control genes, when deregulated, can cause cells that are not dividing to enter the cell cycle and begin to proliferate leading to cancer development. They do so by interfacing with the basic cell cycle regulatory machinery to activate cell cycle entry. There is at present much optimism about the possibility of finding anticancer drug treatment strategies that modulate cell cycle regulatory molecules. Candidate targets for such strategies include crucial cell cycle molecules involved in G(1) to S phase or G(2) to M phase transition. This review will outline the basic regulatory machinery responsible for catalyzing cell cycle entry and describe the latest advances made in the field of cell cycle regulation. The basis of targeting the cell cycle particularly the Cdks as an approach to developing novel, specific and perhaps more effective anticancer treatments will be discussed. Examples of novel cell cycle-targeting agents that are in, or are close to being in clinical trials will be provided.
Multiple trusted devices authentication protocol for ubiquitous computing applications (2012)

The dynamicity of ubiquitous application environment where devices are free to connect and disconnect has made it exposed to adversaries. Identity impostor, man-in-the-middle attack and unauthorized access are some of the threats posed by the potential adversaries. These threats exist due to the lack of good authentication protocol for ubiquitous application environment. As a result, some users are keeping their distance from such applications. In this paper, a new authentication protocol which employs multiple trusted devices to validate other device's identity is introduced. The proposed protocol is somewhat different with the other authentication protocols in sense that it could avoid a single point of failure, promotes decentralization and also implements trust level in granting access. It is hoped that by implementing the proposed protocol, the integrity of the entities involved in a ubiquitous computing applications can be increased.
Grass-cutting research: a symbolic case study in research funding (1969)

En este estudio de caso satírico el autor plantea un conjunto de reflexiones acerca de las políticas de financiamiento que las instituciones públicas tienen con respecto a la investigación en Ciencias Sociales. Por ejemplo, el autor afirma que los investigadores en una democracia deben educar a la opinión pública acerca de la necesidad de apoyar investigaciones de alta calidad. Cuando esto no se da, cuestiones políticas determinan las prioridades antes que el sentido común o la necesidad científica.
Transform coding of high quality digital audio at low bit rates-algorithms and implementation (1990)

Low-bit-rate coding schemes for coding high-quality digital audio at bit rates of 64 to 128 kbit/s per channel are described. LC-ATC (low-complexity adaptive transform coding) and OCF (optimum coding in the frequency domain) both use transform coding to get high redundancy removal and high adaptation to the perceptual requirements. OCF uses entropy coding of the spectral values for increased coding efficiency and flexibility of the coder. Real-time implementations using the DSP32(C) and DSP 56000 digital signal processors are presented for both algorithms. Results using listening tests and noise-to-mask ratio are given: CE quality can be achieved at 2 bit/sample. At 64 kbit/s, the quality at 15 kHz bandwidth is still higher than today's FM radio.< <ETX xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">></ETX>
Signal prediction by an optically controlled neural network (1991)

Networks of interconnected nonlinear analog processors, or neurons, are finding increasing use in adaptive problems. Adaptive signal prediction has been widely used for many years but has been primarily restricted to linear systems and signals, for which the mathematical treatment of the problems is tractable. We present results using an optically controlled adaptive neural network for nonlinear signal prediction.
A secure DHT-based key distribution system for attribute-based encryption and decryption (2015)

Today, sharing information is ubiquitous in a connected world. However, several disadvantages exist, such as the loss of control over data or unwanted data processing and analysis by providers. A central data storage, which is applied by Online Social Networks (OSN), such as Facebook or driven by the government, such as storing medical health data of citizens centrally, is likewise affected. Efforts to store citizens' medical data centrally, driven by political, economic or IT-security reasons, bear the risk of data leakage. We envision a decentralized and data-owner-centric system, capable to support secure data sharing within private or business driven scenarios. A central aspect is to increase management capabilities, such as revocation for the data to be shared, while supporting fine grained access policies provided by Attribute-based Encryption (ABE). In this paper we introduce the Entrance system architecture, requirements and basic use-cases before we reach our main contribution: we discuss challenges and provide solutions arising from applying a Distributed Hash Table (DHT) for an Attribute-based Encryption (ABE) key distribution. We present algorithms for an enhanced encryption and decryption, and introduce the property of Ciphertext Expiration.

Fibre-optic gamma-flux monitoring in a fission reactor by means of Cerenkov radiation (2007)

We demonstrate the possibility of using Cerenkov radiation to monitor the\nreactor power and the high energy gamma-ray flux in a high neutron flux\nreactor. The system employs a radiation-resistant pure silica glass fibre to\nmeasure the Cerenkov radiation in the infrared region (800–1100 nm). A\nmodel is proposed to determine the order of magnitude of the gamma-ray\nflux from the measurement. The method and concept can be extended to the\nmonitoring of low reactor powers if Cerenkov radiation is measured in the\n450–500 nm region by means of hydrogen-treated fibres.
Clinical effects of bifidobacterium preparations on pediatric intractable diarrhea. (1987)

We investigated the effects of administration of Bifidobacterium preparations and commercially available Bifidus Yogurt on infantile intractable diarrhea. Fifteen patients with intractable diarrhea were treated from 1982 to 1985. These patients (11 boys and 4 girls) ranged in age from 1 month to 15 years (mean 2.5 years) and received antibiotic therapy for the treatment of such diseases as septicemia and respiratory tract infections. During treatment, waterly diarrhea appeared and lasted for 1 to 10 weeks (mean 25 days) with deterioration of the general condition. Conservative therapy such as diet control, infusion and drug therapy could not cure the diarrhea. The antibiotics used included cephems, penicillins and aminoglycocides. In most cases, abnormal microflora was observed: Candida or Enterococcus often predominated with a marked decrease of anaerobes and aerobes in the stool flora. During the disease, we could not detect any pathogens or toxins responsible for the diarrhea. In all patients, the stool frequency and appearance were dramatically improved within 3 to 7 days after oral administration of Bifidobacterium preparations of bifidus yogurt. The intestinal microflora of all subjects also became normal with predominance of resident Bifidobacterium or administered B. breve.

Prochymosin expression in Bacillus subtilis (1991)

Prochymosin (PC) sequence was cloned in Bacillus subtilis using two kinds of plasmid constructions. In plasmid pSM316 the cDNA was inserted to obtain the intracellular expression of the enzyme. The enzyme turned out to be expressed in an insoluble form which could be converted to native enzyme under proper denaturing and refolding conditions. The levels of intracellular expression of PC were further enhanced by modifying the 5' region of the gene in a way that a two-cistron expression system was created. For the PC secretion, the cDNA was fused to the subtilisin leader sequence and expressed under the control of the B. subtilis neutral protease promoter. A properly folded PC was secreted by the cells, although to low levels.
A Development of Surgical Simulator for Training of Operative Skills using Patient-Specific Data (2011)

At the Advanced Medical Research Center at Yokohama City University School of Medicine, we have been developing a practical surgical simulator for renal surgery. Unlike already commercialized laparoscopic surgical simulators, our surgical simulator is capable of using patient-specific models for preoperative training and improvement of laparoscopic surgical skills. We have been evaluating the simulator clinically with the aim of using it in renal surgery training at Yokohama City University Hospital. The simulator can be applied to other types of laparoscopic surgery, such as gynecological, thoracic, and gastrointestinal. Here, we report on the technical aspects of the simulator.

Effect of Heat on the Sterilization of Artificially Contaminated Water (1996)

Groh et a1 have published a simple, yet informative experiment in this issue of thelournal ofTravel Medicine to challenge a commonly held belief that water must be boiled for up to 10 minutes to render it safe to drink.They conclude that sustained boiling is not necessary; furthermore, achieving the boiling temperature of 1 OOOC is not necessary.While I agree with their conclusions, they are making an assumption that cannot be supported by their data, which are based only on testing enteric bacteria.However, other data exist to help support their conclusion.While enteric bacteria, especially enterotoxigenic Escherichiu coli account for the majority of travelers' diarrhea, other classes of microorganisms, including viruses and protozoa, regularly account for a small percentage of cases.At certain tinies and locations, these other pathogens may even be the predominant etiologic agents.Adequate preventive measures are important because these pathogens will not respond to the presumptive antibiotic therapy recornmended for traveler's diarrhea.'Water treatment is an essential component in the prevention strategy of enteric infections.The issue of heating or boiling water is important because this method is used worldwide by local residents, travelers and campers to provide safe drinking water.It is also recommended in countries with nornidly safe drinking water as backup in emergencies or when water systems have beconie contaminated by floods or a lapse in water treatment plant efficacy.In addition to heat, methods available for iinproving microbiologic and aesthetic qualities of water for travelers include halogens (iodine and chlorine), filtration, and clarification techniques.'The main advantages of using heat are that it is widely available and it imparts no
Laser‐Generated Supranano Liquid Metal as Efficient Electron Mediator in Hybrid Perovskite Solar Cells (2020)

Creating colloids of liquid metal with tailored dimensions has been of technical significance in nano-electronics while a challenge remains for generating supranano (<10 nm) liquid metal to unravel the mystery of their unconventional functionalities. Present study pioneers the technology of pulsed laser irradiation in liquid from a solid target to liquid, and yields liquid ternary nano-alloys that are laborious to obtain via wet-chemistry synthesis. Herein, the significant role of the supranano liquid metal on mediating the electrons at the grain boundaries of perovskite films, which are of significance to influence the carriers recombination and hysteresis in perovskite solar cells, is revealed. Such embedding of supranano liquid metal in perovskite films leads to a cesium-based ternary perovskite solar cell with stabilized power output of 21.32% at maximum power point tracing. This study can pave a new way of synthesizing multinary supranano alloys for advanced optoelectronic applications.
Exact ARMA lattice predictors from autocorrelation functions (1994)

The paper derives an optimal linear L/sup 2/-predictor of ARMA-type in the lattice form of arbitrarily fixed dimensions for a process whose autocorrelation function is known. The algorithm preserves exact optimality at each step, as opposed to asymptotic convergence of more usual algorithms, at the expense of hereditary computation. Only the discrete-time case is examined. It is shown how the unnormalized (respectively normalized) lattice form may be reduced to only 4n-2 parameters (respectively 2n+1) for a nth-order projection on the past. The normalization algorithm for the forward and backward residuals uses only scalar square root computations. Some examples that show the accuracy of this technique compared with those using the classical ARMA form for the predictor, are given.< <ETX xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">></ETX>
Dynamic Modeling and Simulation of a Yaw-Angle Quadruped Maneuvering With a Planar Robotic Tail (2016)

This paper analyzes the impact a planar robotic tail can have on the yaw-angle maneuvering of a quadruped robot. Tail structures ranging from a one degree-of-freedom (1DOF) pendulum to a 6DOF serpentine robot are simulated, along with a quadruped model that accounts for ground contact friction. Tail trajectory generation using split-cycle frequency modulation is used to improve net quadruped rotation due to the tail's motion. Numerical results from the tail and quadruped models analyze the impact of trajectory factors and tail structure on the net quadruped rotation. Results emphasize the importance of both tangential and centripetal tail loading for tail trajectory planning and show the benefit of a multi-DOF tail.
<b>Practice Prize Report</b>—An Assortmentwide Decision-Support System for Dynamic Pricing and Promotion Planning in DIY Retailing (2007)

The main objective of this report is to describe a decision-support system for dynamic retail pricing and promotion planning. Our weekly demand model incorporates price, reference price effects, seasonality, article availability information, features, and discounts. Building on previous research, we quantify demand interdependencies and integrate the resulting profit-lifting effects into the optimal pricing model. The methodology was developed and implemented at bauMax, an Austrian do-it-yourself retailer. Along with the practical requirements, an objective function was employed that can be used as a vehicle for implementing a retailer’s strategy. Eight pricing rounds with thousands of different stock-keeping units have each served as a testing ground for our approach. Based on various benchmarking methods, a positive impact on profit was reported. The currently implemented marketing decision-support system increased gross profit on average by 8.1 and sales by 2.1%.
Inflammatory Bowel Disease Characteristics Among African Americans, Hispanics, and Non-Hispanic Whites: Characterization of a Large North American Cohort (2006)

A new procedure for fundus photography and fluorescein angiography in small laboratory animal eyes (1994)

Increasing interest in retinal research demands continuous improvement of experimental techniques and interpretation. Thus, the purpose of our research was to devise a new method for funduscopic photography and fluorescein angiography in the normal or diseased retina of the small laboratory animal that would produce results comparable in optical quality and field coverage to those obtained in human clinical practice. To enhance the view of the small eye, a 2.2 Volk Panretinal lens was held in apposition to the lens of a clinical fundus camera, the Topcon TRC 50FT, by means of a custom made metal sleeve. Albino mice, albino rats, and pigmented rats were photographed. Fluorescein angiography was performed on pigmented rats. Fluorescein was administered intravenously via the jugular vein at a dose of 5 mg/kg. Various speeds of film and flash settings were used depending on the light source and the pigmentation of the animal. Attachment of the 2.2 Panretinal lens to the clinical fundus camera allowed for more clearly defined fundus photographs of the small laboratory animal, as well as an enlarged field of observation over conventional techniques. Consequently, angiography fields and stages documented in the small laboratory animal approximated those obtained in human clinical practice. This technique facilitates the visualization of small fundi and it allows for a fuller documentation of experimental retinal models.
