Enhancing network management frameworks with SDN-like control (2013)

Traditional network management tools are too static and inflexible in today's enterprise and campus networks that have to support users with diversity of personal devices. Controller-based Software Defined Networking (SDN) paradigms are gaining popularity because of their promise to reduce the complexity of managing networks by automating the complex process of translating policy definitions to network provisioning and dynamic control. Though this approach provides fine-grained control over end-to-end network flows, they lack mature management and control tools. We propose an integrated network management and control system (i-NMCS) framework that combines legacy network management functions such as discovery, fault detection with the end-to-end flow provisioning and control enabled by SDN. We believe that such hybrid control will be key for incremental deployment of SDN functionality on today's networks.
Pediatric Vesicoureteral Reflux Guidelines Panel Summary Report on the Management of Primary Vesicoureteral Reflux in Children (1997)

For most children the panel recommended continuous antibiotic prophylaxis as initial treatment. Surgery was recommended for children with persistent reflux and other indications, as specified in the document.
De-duplication in KOBV (1999)

In KOBV we offer the user an efficient tool for searching regional and worldwide accessible library catalogues (KOBV search engine). Search is performed by a distributed Z39.50 retrieval and an index based quicksearch. Due to the number of catalogues, result sets may contain a significant amount of duplicate records. Therefore we integrate a de-duplication procedure into KOBV search engine. It is part of the distributed search and the KOBV quicksearch as well. Main goals are the presentation of uniform retrieval results, the preservation of retrieval quality and cutting off redundant information. At least we keep an eye on efficiency. De-duplication is fully parametrizable, so that settings can be changed easily on line.
Inhibition of accelerated cardiac allograft arteriosclerosis by fish oil. (1989)

Accelerated coronary arteriosclerosis remains the most important factor limiting long-term survival of heart transplant recipients, and dietary fish oil supplementation with omega-3 polyunsaturated fatty acids has been suggested to have a protective effect against coronary disease in epidemiologic studies and to inhibit arteriosclerosis in animal experiments. Therefore we tested the hypothesis that fish oil administration inhibits the development of allograft coronary arteriosclerosis by using a heterotopic heart transplant model. Three groups of Lewis rats (n = 10 each) received heterotopic heart transplants from Brown-Norway donors and were treated with cyclosporine intraperitoneally on a tapering schedule. Group 1 received fish oil daily by gavage (2 ml/kg/day; Emulsified Super MaxEpa, Twin Labs, Ronkonkona, N.Y.). Group 2 received an equal amount of safflower oil, as well as aspirin (1 mg/kg/day) and dipyridamole (3 mg/kg/day). Group 3 received safflower oil only. All rats were put to death 110 days later, at which time there was no statistically significant difference in graft function as assessed by palpation (scale 0 to 4, mean = 3.7 +/- 0.5 [+/- standard deviation]; analysis of variance: p = 0.72) or in microscopic grade of rejection (scale, 0 = none to 3 = severe, mean 2.1 +/- 0.6; analysis of variance: p = 0.68) between any of the groups. The coronary arteries were histologically scored for the degree of arteriosclerosis (scale, 0 = normal to 3 = occluded), and a mean grade of coronary disease was calculated for each heart. The fish oil-treated group had significantly less severe allograft coronary arteriosclerosis (analysis of variance: p = 0.005) than did groups 2 and 3 (mean grade 0.23 +/- 0.22 versus 1.04 +/- 0.75 and 0.96 +/- 0.55 (p less than 0.05, Scheffe F test), whereas groups 2 and 3 had similar degrees of coronary disease (p = no significant difference). These data demonstrate that fish oil supplementation inhibited accelerated coronary arteriosclerosis in this cyclosporine-treated heart allograft rat model, whereas antiplatelet agents in these doses were ineffective. Although the mechanism of this protective effect remains incompletely understood, it does not appear to involve enhanced immunosuppression. Fish oil and specific omega-3 polyunsaturated fatty acids should be further investigated as potentially useful agents to ameliorate accelerated allograft coronary arteriosclerosis in other animal species and perhaps eventually in man.
Reassessing the Principal's Role in School Effectiveness: A Review of Empirical Research, 1980-1995 (1996)

Although the is little disagreement conquering the belief that principals have an impact on the lives of teachers and students, both the nature and degree of this effect continues to be open to debate. The relationship is complex and not easily subject to empirical verification. This article reviews the empirical literature on the relationship between the principal's role and school effectiveness during the period from 1980 to 1995. We specifically focus on the conceptual underpinnings of several theoretical models to study the role, the relationship between models and methods of investigation, an4 consequently, to what has been learned about the nature of the principal impact. We conclude by framing a possible research agenda for the next generation of studies on the effects of school administration.

Analysis and design of series combining transformers for integrated Doherty power amplifiers (2010)

In this paper, analysis and design of a series combining transformer based integrated Doherty PA is presented. A Z-parameter based model is used to optimize the series combining transformer(SCT) for Doherty operation. The proposed 2.4 GHz fully integrated Doherty Power Amplifier is fabricated in standard 90 nm CMOS technology and aimed for high linearity WLAN applications. The measurement results indicate that the PA shows efficiency enhancement at power back-off due to Doherty operation. The PA delivers 20.5 dBm output power with a peak drain efficiency of 30.9% (PAE 26.7%) by using 2 V supply voltage. The two stage Doherty PA has 16.6 dB small signal gain and 1 dB compression occurs at 17.5 dBm output power.

On Physical Problems that are Slightly More Difficult than QMA (2014)

We study the complexity of computational problems from quantum physics. Typically, they are studied using the complexity class QMA (quantum counterpart of NP) but some natural computational problems appear to be slightly harder than QMA. We introduce new complexity classes consisting of problems that are solvable with a small number of queries to a QMA oracle and use these complexity classes to quantify the complexity of several natural computational problems (for example, the complexity of estimating the spectral gap of a Hamiltonian).

CueR (YbbI) of <i>Escherichia coli</i> is a MerR family regulator controlling expression of the copper exporter CopA (2001)

We have shown that the open reading frame ybbI in the genomic sequence of Escherichia coli K-12 encodes the regulator of expression of the copper-exporting ATPase, CopA. In vivo studies showed that ybbI (designated cueR for copper export regulator gene) was required for copper tolerance during growth, that disruption of cueR caused loss of copA expression and that copA gene expression was regulated by cueR and by copper or silver ions. Expression of a lacZ reporter gene under the control of the copA promoter was approximately proportional to the concentration of cupric ions in the medium, but increased more rapidly in response to silver ion concentrations. The start of the copA transcript was located by primer extension mapping, and DNase I protection assays showed that the CueR protein binds in vitro to a dyad symmetrical sequence within a 19 bp spacer sequence in the copA promoter. CueR binding occurs in vitro in both the presence and the absence of RNA polymerase with or without copper ions present but, in the presence of CueR, RNA polymerase and copper ions, permanganate-sensitive transcription complexes were formed. CueR is predicted to have an N-terminal helix-turn-helix sequence and shows similarity to MerR family regulators.
Herd behavior and aggregate fluctuations in financial markets (1997)

We present a simple model of a stock market where a random communication structure between agents gives rise to a heavy tails in the distribution of stock price variations in the form of an exponentially truncated power-law, similar to distributions observed in recent empirical studies of high frequency market data. Our model provides a link between two well-known market phenomena: the heavy tails observed in the distribution of stock market returns on one hand and 'herding' behavior in financial markets on the other hand. In particular, our study suggests a relation between the excess kurtosis observed in asset returns, the market order flow and the tendency of market participants to imitate each other.
The GEO satellites and space debris optical angle measuring system (2012)

A small diameter optical telescope with a drift scanning CCD camera, the associated softwares and hardwares can be combined to constitute a set of optical angle measuring system. The alternation between the drift scanning mode and the staring mode for observing the background stars and the GEO objects, makes the GEO satellite optical observations to become more convenient and greatly reduces the observing intensity. By means of high-precision astrometric catalog, the ground-based optical angle measuring system can provide high-precision angle measurement data of the GEO satellites and space debris, and thus achieve accurate orbit determination for them. The analysis results of observation show that the system can provide much more precious angle measurement data with a small diameter telescope than the current technologies, and the difference of the precision can be up to an order of magnitude.
Metrological characteristics of a group of quadrupole partial pressure analyzers (1990)

Linearity and stability of the pressure response of five different commercial quadrupole partial pressure analyzers and the influence of ion source parameters (emission current, electron energy, and ion energy) on the response has been investigated over the range 10−7–10−1 Pa for He, N2, and Ar. In the 10−3–10−1 Pa range, each instrument developed a maximum (as large as a factor of 100 in one instrument) in the sensitivity versus pressure relation when operated with ‘‘low’’ ion energy (about 2–3 eV). All but one of the instruments also showed significant low-pressure nonlinearity, down to pressures as low as 10−7 Pa in one instrument, when operated at ‘‘high’’ ion energies (greater than about 7 eV). These results bring into question the often-assumed linearity of such instruments at low pressures. The dependence of the signal developed from a constant pressure (10−6 Pa) trace gas as a function of the pressure of another gas (the matrix) was studied using He and Ar as the trace and matrix, and vice versa. The results demonstrated an apparent correlation between the magnitude of this dependence, and an instrument’s nonlinearity as a function of pressure with the matrix gas alone. Brief exposures to certain active gases (O2, C3H8, CO2, CO) were found to cause shifts as large as 10% in the instruments’ inert gas sensitivities (He, N2, Ar). Tens of hours were required to return to pre-exposure sensitivities. Absolute argon sensitivity, monitored over a period of 220 days, for a standard set of operating parameters and with Faraday cup ion detection, showed initial one-directional changes as large as a factor of 2 for one instrument and a scatter of about ±20% in all the instruments. The very large differences among the five test instruments with regard to sensitivity, linearity, and stability, as well as the influence of one gas on the sensitivity to another, point out the need for careful characterization and calibration of such instruments for all except the most qualitative applications.
Stochastic scattering in charged particle projection systems: A nearest neighbor approach (1995)

Image blurring as a result of stochastic particle–particle interactions has been investigated for projection electron- and ion-beam lithography systems. A comparative analysis of the currently available analytical theories is presented. The results from these theories are also compared with Monte Carlo simulation results and experimental data. Large variations in results and serious disagreements between the different theoretical approaches are found. We have formulated a new theory on the basis of a simple, analytical approach that overcomes most of the difficulties experienced by earlier theories with two key concepts: consideration of nearest-neighbor interactions only, and a randomization length, over which the interactions are correlated. Our model displays satisfactory functional and numerical agreement with Monte Carlo simulation results over a large range of beam currents, as well as with the only available experimental data. The physical basis of our model also enables us to understand the origins of the discrepancies arising from earlier theories.

Enhancing electronic combat system digital signal processing using neural networks (2003)

The study focuses on the use of neural networks in three distinct areas of electronic combat (EC) signal processing: pulse sorting, pulse repetition interval (PRI) analysis, and emitter identification. Results of testing using neural networks show that neural networks have the potential to outperform conventional software in many cases. Pulse sorting is especially promising due to the way in which the Kohonen self-organizing map sorts pulses with ambiguous pulsewidth or frequency values. PRI analysis yields good results even when pulses have been dropped or in the presence of noise. It has been shown that the conventional software used for preprocessing PRI analysis input data is critical to the success of the network. While neural networks may never totally supplant conventional EC software, they can certainly be used effectively to enhance EC systems.< <ETX xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">></ETX>
Molecular Relationships and Classification of Some Viridans Streptococci as Streptococcus oralis and Emended Description of Streptococcus oralis (Bridge and Sneath 1982) (1985)

Nucleic acid hybridization studies together with a chemical cell wall analysis and physiological data indicated that some strains designated as Streptococcus sanguis II, Streptococcus sp. (“S. mitior”-S. sanguis), and “S . viridans” I, II, and IV are closely related to the type strain of S. oralis. These strains contained a directly cross-linked peptidoglycan with lysine as a diamino acid and ribitol and choline as characteristic cell wall constituents. We propose that these strains be classified as members of S. oralis. An emended description of S. oralis is given. S . oralis strains are genetically related to S. pneumoniae strains, and representatives of both species contain ribitol and choline in their cell walls.
Performance of Zirconium and Zirconium Alloys in Organics (1996)

Abstract Zirconium and its alloys are well known for their corrosion resistance in a broad range of inorganic and organic media. They have played a key role in advancing the production technologies of urea and formic, acetic, hydroxyacetic, lactic, and methacrylic acids, methyl methacrylate, rayon, alcohols, and phenolic resins, etc. Laboratory data and case histories are used to demonstrate the advantages of zirconium and its alloys. Compared to other engineering alloys, the use of zirconium and its alloys allows producers to make products of high quality by operating processes at higher temperatures/pressures for improved efficiency and yield. Unlike many metallic ions, zirconium produces colorless ions. Most transition metals produce ions of different colors depending on their valence state. An increasingly important advantage is that zirconium appears to be nontoxic and biocompatible. Limitations of zirconium and its alloys in organics are also discussed. They may be vulnerable in certain organic halides, such as acetyl chloride, that are incompatible with water. In water-soluble organics, such as methanol, water is necessary to inhibit localized corrosion. There are impurities, such as copper ions in acetic acid, that are undesirable for zirconium and its alloys. Control measures, such as water addition and stress relieving, can be applied to zirconium equipment in certain extreme conditions.
Kallikrein genes (1988)

Genes for the small human glandular kallikrein gene family were isolated. Members of this family include renal/pancreatic kallikrein, prostate-specific antigen and a kallikrein encoded by the first gene that was isolated and completely sequenced, hGK-1. All share strong nucleotide sequence homology, although hGK-1 and the prostate-specific antigen gene are more closely related (86% identity in coding nucleotides). Renal/pancreatic kallikrein has 77% nucleotide homology to prostate-specific antigen, but only 60% amino acid homology. There is strong homology in the 5'-flanking DNA with mouse kallikrein genes, suggesting common regulatory mechanisms. In the rat one-kidney, one clip model of hypertension, renal kallikrein messenger (m)RNA increased during the initial transient rise in plasma renin, and then decreased.
Scheduling constant bit rate flows in data over cable networks (2003)

The Data Over Cable Systems Interface Specification (DOCSIS) is the leading standard for data over cable networks. We consider the problem of scheduling constant bit rate (CBR) flows in a DOCSIS compliant cable network. CBR flows are required to support the delivery of voice and other real-time applications that generate fixed size data packets on a periodic basis. The primary application of CBR flows is voice over IP (VoIP) which cable operators intend to use in order to provide cable telephony services. DOCSIS 1.1 is enhanced with quality of service (QoS) capabilities; it defines the unsolicited grant service as the mechanism for supporting CBR flows. The scheduling algorithms, however, are not defined by the standard. We present the scheduling problem and examine several interesting special cases of it. We show that deciding whether a set of CBR flows can be legally scheduled is NP-complete whenever there are two or more different grant intervals. We model the scheduling problem as a variant of bin packing where bin sizes can be modified in a constrained manner This model enables the development of scheduling algorithms which are based on known algorithms for bin packing. We present an algorithm based on the next-fit algorithm and investigate its performance. We show that under certain assumptions which typically hold for VoIP and many other practical applications, a simple polynomial time scheduling algorithm is sufficient.
Cracking Open the Black Box (2019)

Machine learning (ML) solutions to challenging networking problems, while promising, are hard to interpret; the uncertainty about how they would behave in untested scenarios has hindered adoption. Using a case study of an ML-based video rate adaptation model, we show that carefully applying interpretability tools and systematically exploring the model inputs can identify unwanted or anomalous behaviors of the model; hinting at a potential path towards increasing trust in ML-based solutions.
Characteristics of dielectric-tube-loaded coaxial cables (1972)

A study of the complete mode spectrum of the dielectric-tube-loaded coaxial cable reveals that only the low-loss slow-wave TM01 mode has no lower cutoff frequency. Mode designations are shown to be consistent with those previously adopted for dielectric waveguides. A numerical optimisation procedure is applied to an accurate perturbation analysis of the dominant mode to determine optimum dielectric-tube radial dimensions for minimum loss. Attenuation reductions as high as 75% of the unloaded values are attainable in certain overmoded cases. For the optimum conditions, the cable is well equalised, and the propagation characteristics are relatively insensitive to small variations in the dimensions of the tube.
