Physical-Layer Adaptive Resource Allocation in Software-Defined Data Center Networks (2018)

With the deep physical-layer programmability enabled by software-defined networking (SDN), it is now feasible to realize optical data center transceivers that adapt their transmission parameters in response to time-varying traffic demand and signal quality conditions. In this paper, we develop a cross-layer performance tuning framework for wavelength-tunable data center transceivers, combining scalable and secure modulation order and code rate adaptation. We develop new physical-layer control modules and combine SDN control with distributed preamble encoding in order to achieve both rate adaptation and node synchronization in a wavelength-routing data center testbed. Our experimental and theoretical studies based on pulse amplitude modulation and low-density parity-check coding point to the significance of joint modulation order and code-rate adaptation in data centers. We report real-time resource adaptation with switching speeds on the order of hundreds of milliseconds.
Dexmedetomidine: Applications in pediatric critical care and pediatric anesthesiology (2007)

The literature contains reports of the use of dexmedetomidine in approximately 800 pediatric patients. Given its favorable sedative and anxiolytic properties combined with its limited effects on hemodynamic and respiratory function, there is growing interest in and reports of its use in the pediatric population in various clinical scenarios.
Characterization of the Insulin-regulated Membrane Aminopeptidase in 3T3-L1 Adipocytes (1996)

A novel membrane aminopeptidase has been identified as a major protein in vesicles from rat adipocytes containing the glucose transporter isotype Glut4. In this study we have characterized this aminopeptidase, referred to as vp165, in 3T3-L1 adipocytes. The subcellular distributions of vp165 and Glut4 were determined by immunoisolation of vesicles with antibodies against both proteins, by immunofluorescence, and by subcellular fractionation and immunoblotting. Relative amounts of vp165 at the cell surface in basal and insulin-treated cells were assayed by cell surface biotinylation. These experiments showed that vp165 and Glut4 were entirely colocalized and that vp165 increased markedly at the cell surface in response to insulin, in a way similar to Glut4. When intact cells were assayed with a novel, membrane-impermeant fluorogenic substrate for vp165, we found that insulin stimulated aminopeptidase activity at the cell surface. This observation provides direct evidence for the functional consequence of vp165 translocation.
Metabolism of GABA in retina of diabetic rat (1999)

The effect of hyperglycemia on the localization and metabolism of gamma-aminobutyric acid (GABA) was examined to elucidate the pathogenesis of deteriorations of electroretinogram oscillatory potentials in streptozotocin-induced diabetic rats. GABA is localized primarily in amacrine cells in the diabetic retina. GABA content and activities of glutamate decarboxylase (GAD) and GABA transaminase (GABA-T) in the retina and superior colliculus (SC) were determined. GABA content and activities of GAD and GABA-T remained unchanged in retinas and SCs of diabetic rats. Alterations in the GABAnergic system of the retina could not be observed. GABA metabolism may have no relation with visual dysfunction in diabetes mellitus.
Histological Study on Testis of Grower and Adult Wistar Rat (2013)

The present study was conducted on testes of grower (20-30 days) and adult (50-60 days) Wistar rats having 10 animals in each group. The thickness of tunica albuginea, average diameter of seminiferous tubule and number of Sertoli cells per seminiferous tubule were significantly higher in adults than growers, whereas number of interstitial cells per field were significantly higher in growers than adults of Wistar rat. The reproductive performance of the animals can be better understood by testicular histomorphometry
Resuscitation after prolonged cardiac arrest: effects of cardiopulmonary bypass and sodium–hydrogen exchange inhibition on myocardial and neurological recovery☆ (2011)

CPB is an effective resuscitative tool to treat prolonged CA but there is limited improvement of neurological function. NHE inhibition augments cardiac and neurological function, but its effect was less pronounced than in other studies.
A Sentiment-based Hybrid Model for Stock Return Forecasting (2013)

Real-world financial time series often contain both linear and nonlinear patterns. However, traditional time series analysis models, such as ARIMA, hold the assumption that a linear correlation exists among time series values while leaving nonlinear relation into error terms. Based on financial theories, we argue that investor sentiment is the main contributor to nonlinear pattern of stock time series. Furthermore, we propose a sentiment-based hybrid model (SLNM) to better capture nonlinear information in stock time series. According to the forecasting experimental results, SLNM exhibits the sensitivity to sentiment environments, which in turn supports the argument that investor sentiment is the main source of nonlinear pattern in stock time series. For those stocks that are in top 10 of CAR Ranking List ─ these stocks are more likely pursed by emotional investors and thus in optimistic sentiment environment, SLNM improves forecasting performance dramatically: Increase Direction Accuracy by 40% and reduce RMSE by 19.3%. While, for those that are in bottom 10 of CAR Ranking List─ these stocks defer more emotional investors from further participating in stock trading and thus in pessimistic sentiment environment, SLNM has a fair improvement on performance: Hold the similar Direction Accuracy and reduce RMSE only by 2.5%. All these indicate that investor sentiment play a key role in stock return forecasting. Our work sheds light on the research of sentiment-based prediction models.
Early Postoperative Glucose Control Predicts Nosocomial Infection Rate in Diabetic Patients (1998)

We conclude that diabetic patients undergoing major cardiovascular or abdominal surgery have an increased risk of infection that is further exacerbated by early postoperative hyperglycemia. The high rate of nosocomial infection observed in diabetic patients with poor glucose control suggests that hyperglycemia itself may be an independent risk factor for the development of infection. Efforts to improve perioperative glucose homeostasis in diabetic patients may reduce the incidence of nosocomial infection and thereby improve outcome.
Symbolic Generation of an Optimal Crout Algorithm for Sparse Systems of Linear Equations (1970)

An efficient implementation of the Crout elimination method in solving large sparse systems of linear algebraic equations of arbitrary structure is described. A computer program, GNSO, by symbolic processing, generates another program, SOLVE, which represents the optimal reduced Crout algorithm in the sense that only nonzero elements are stored and operated on. The method presented is particularly powerful when a system of fixed sparseness structure must be solved repeatedly with different numerical values. In practical examples, the execution of SOLVE was observed to be typically N times as fast as that of the full Crout algorithm, where N is the order of the system.
Use of a dielectric-loaded cylindrical cavity in measurements of the microwave surface resistances of high-T/sub c/ superconducting thin films (1997)

An analysis of the axially symmetric TM/sub 011/ mode in a dielectric-loaded cavity is presented and a technique of using a TM/sub 011/ mode dielectric-loaded cavity is introduced for measurements of microwave surface resistances of HTS thin films. A dielectric resonator with /spl epsiv//sub r//spl ap/39 is used for this purpose. It turned out that Q of the TM/sub 011/ mode dielectric-loaded cavity is very sensitive to the surface resistance of the material at the bottom plate, especially to the surface resistance of the area under the dielectric resonator, which can be used to investigate local microwave properties of large HTS thin films in a nondestructive, simple way. Experiments on YBCO thin films with the dimensions of /spl sim/2/spl times/2 cm/sup 2/ are performed using this technique, which revealed inhomogeneity in the microwave surface resistance of the thin films at different sites and demonstrated the usefulness of this technique.
Peak-to-average power ratio reduction of OFDM signals using broadband pulse shaping (2003)

Orthogonal frequency division multiplexing (OFDM) techniques allow the transmission of high data rates over broadband radio channels subject to multipath fading without the need for powerful channel equalization. However, they are very sensitive to nonlinear effects due to the high peak-to-average power ratio (PAPR) owned by the transmitted signal. This paper proposes an efficient technique for reducing the PAPR of OFDM signals. The proposed technique is very effective and flexible. The method avoids the use of extra inverse fast Fourier transformations (IFFT) as was done in some previously published techniques but instead is based on a proper selection of the time waveforms of the different subcarriers of the OFDM modulation scheme. Thus, its implementation complexity is much lower in comparison to the previous published methods. A closed form relation between the maximum PAPR and the used pulse shaping waveform is derived. The obtained results show that with broadband pulse shaping, the PAPR of OFDM modulated signals can be made very close to that of single carrier signals. The improved statistics of the PAPR in the transmitted signal is demonstrated through numerical results for some sets of time waveforms. The significant improvement in PAPR given by the present technique permits us to reduce the complexity and cost of the transmitter significantly. In that, pulse shaping can be used not only to shape the spectrum of the transmitted signal but also to reduce its PAPR.
Eosinophils as a Source of Matrix Metalloproteinase-9 in Asthmatic Airway Inflammation (1997)

Bronchial asthma is characterized by eosinophil infiltration and tissue remodeling. Matrix metalloproteinases (MMPs) are thought to play critical roles by degradating interstitial matrices in a wide range of lung diseases associated with reorganization of the airway architecture. To investigate whether MMPs are involved in the pathologic processes of bronchial asthma, we examined MMP expression in asthmatic subjects. In situ hybridization revealed abundant expression of MMP-9 (gelatinase B) mRNA in biopsy specimens from asthmatic subjects (n = 5), with an average positive cell distribution of 117.8 +/- 41.1 (mean +/- SEM)/mm2. In contrast, sparse expression of the mRNA (10.8 +/- 4.8 /mm2) was observed in specimens from normal subjects (n = 4). The vast majority of cells expressing the mRNA were eosinophils in asthmatic tissues (92.2 +/- 1.2%). MMP-9 protein, which was confined to the submucosal cells in the normal subjects, was not abundantly expressed in inflammatory cells, but there was positive reactivity for MMP-9 protein in the extracellular matrix. Immunoelectron microscopic analysis showed sparse immunolocalization of MMP-9 in the perinuclear spaces of eosinophils, but not in the granules. These findings suggest the overexpression of MMP-9 by eosinophils in bronchial tissues of asthmatic individuals, and the participation of MMPs in the pathologic changes in asthmatic airways.
Unrestricted C3 Activation Occurs in Crry-Deficient Kidneys and Rapidly Leads to Chronic Renal Failure (2007)

Deficiency of the C3 convertase regulator Crry is embryonic lethal in mice unless C3 also is absent. For evaluation of the effect of local kidney Crry deficiency in the setting of an intact complement system, Crry(-/-)C3(-/-) mouse kidneys were transplanted into syngeneic C57BL/6 wild-type mice. These Crry-deficient kidneys developed marked inflammatory cell infiltration, tubular damage, and interstitial fibrosis, whereas similar changes were absent in control transplanted kidneys. Strong C3 deposition in the vessels and tubules that correlated significantly with measures of disease supported that complement activation was pathogenic in this model. Microarray studies showed upregulation of a number of chemokine and extracellular matrix genes, which were validated for CCL2 and CXCL10 mRNA and collagen III protein. The functional significance of these pathophysiologic findings was evaluated by removing both native kidneys, so the transplanted kidney alone provided renal function. Within 21 d of transplantation, seven of eight Crry-deficient kidneys in complement-sufficient wild-type hosts failed, compared with two of 13 controls (P = 0.001), with final blood urea nitrogen levels of 133.9 +/- 33.0 and 55.6 +/- 8.3 mg/dl, respectively (P = 0.015). These data show that mouse Crry is a critical complement regulator in the kidney. When absent, unrestricted complement activation occurs and quickly leads to marked inflammation and progressive renal failure, with features relevant to human diseases with underlying defects in complement regulation, such as hemolytic uremic syndrome.
Multi-layer versus single-layer optical cross-connect architectures for waveband switching (2004)

Waveband switching (WBS) in conjunction with multigranular optical cross-connect (MG-OXC) architectures can reduce the cost and complexity of switching nodes. In this paper, we study two MG-OXC architectures: the single-layer and the multilayer MG-OXCs, and compare their performances with both off-line (static) and on-line (dynamic) traffic. In the off-line case, a near-optimal integer linear programming models (called off-ILP models) for each of the MG-OXC architectures aims to reduce the size of the MG-OXC, and compares them with the balanced path routing with heavy-traffic first waveband assignment (BPHT) heuristic developed for the multilayer MG-OXCs. The two architectures are then compared in terms of the number of wavelength a fixed number of wavelengths on each link. We also propose a novel efficient heuristic algorithm, called maximum overlap ratio (MOR) to satisfy new requests and compare it with the on-ILP, first-fit, and random-fit algorithms. We compare the two architectures in terms of the blocking probability, weighted (request) acceptance ratio, which serves as an indication of hops (WH) and MG-OXC ports required to satisfy a given set of traffic demands. In the on-line case, we develop an on-line ILP model called on-ILP, which aims to minimize the number of used ports for each of the MG-OXC architectures, given the revenue generated by satisfying the requests. Our results indicate that using WBS with either single-layer or multilayer MG-OXCs can reduce the number of ports (hence the size and cost) of the switching nodes compared to using ordinary OXCs (without waveband switching). In particular, in the off-line case, using single-layer MG-OXCs provides a greater reduction in size than multilayer MG-OXCs, while in the online case, using the multilayer MG-OXC is better.
Different substrate specificities of the two DNA ligases of mammalian cells. (1986)

Mammalian cells contain the DNA ligases I and II. These enzymes show different molecular weights and heat labilities, and antibodies against ligase I do not inhibit ligase II. Here, the nonidentical substrate specificities of the enzymes are described. Under standard reaction conditions DNA ligase I, but not ligase II, catalyzes blunt-end joining of DNA, while ligase II is the only activity that joins oligo(dT) molecules hydrogen-bonded to poly(rA). These differences facilitate the distinction between the two enzymes and should permit further analysis of their functions.

Inkjet-Printed Paper-Based Colorimetric Sensor Array for the Discrimination of Volatile Primary Amines (2013)

This paper describes a colorimetric sensor array for the discrimination of volatile amines. Analyte discrimination is achieved by combining two functional elements: (1) a "chemical class-selective" single chromogenic sensing dye with selectivity for amines in general, encapsulated into (2) polymer nanoparticles with different polarities. The resulting array has the ability to distinguish one closely related amine from another, relying on a polarity-based approach. In order to achieve reproducible, cost efficient, and flexible sensor array fabrication with the potential for mass production, inkjet-printing technology combined with standard copy paper as a sensor substrate is applied. Printing of 6 types of inks, which are prepared by mixing two dye encapsulating nanoparticles of different polarity in different mixture ratios, results in a colorimetric sensor array with a polarity gradient. Seven primary amines with increasing alkyl chain lengths have been selected to demonstrate the performance of the sensor array. The RGB color differences (ΔR, ΔG, ΔB) of the sensor array spots before and after gas exposure were analyzed by principal component analysis (PCA) and agglomerative hierarchical clustering (AHC) analysis. Under the selected measurement conditions, results of PCA and AHC analysis indicated high discrimination ability with high reproducibility of the sensor array down to amine concentrations of 50 ppm. The discrimination ability was maintained at relative humidities between 10% and 80%. Furthermore, the sensor array showed no significant response to common volatile organic compounds, confirming the high selectivity toward amines. This is, to the best of our knowledge, the first report of a colorimetric sensor array with selectivity for a specific chemical class of analytes and the ability to discriminate compounds of the same class, which is obtained by simply mixing two types of single dye-encapsulating polymer nanoparticles.
System for electron paramagnetic resonance measurements at high pressure and low temperature (1997)

Major improvements have been made on the sensitive high pressure electron paramagnetic resonance (EPR) system developed previously in 1978 at this laboratory. These changes allow low temperature measurements and provide a more stable signal. The high pressure EPR cell is placed inside a vacuum chamber to provide thermal isolation, so that the system may be cooled by a closed cycle refrigerator to temperatures between 45 and 60 K, depending on the energy input to the modulation coil. The combination of high pressure and low temperature greatly expands the thermodynamic range over which EPR measurements can be made. An improved and effective method of forming a conductive surface to define the microwave cavity is presented. This method successfully avoids the deterioration of the sapphire’s polished surface which causes premature breaking of the sapphire high pressure anvil, and therefore significantly improves the reliability of the system at high pressure. Other modifications to the system, such as the microwave coupling method, the modulation coil, and selecting of a hydrostatic pressure fluid, are discussed. EPR measurements on BaTiO3 have been made at temperatures ranging from 233 to 353 K and pressures from 0 to 4.4 GPa. High quality signals can be realized in the entire pressure and temperature range.
4E-1 Periodically Poled Transducers Built on Single Crystal Lithium Niobate Layers Bonded onto Silicon (2007)

In this paper, we present new results on the development of piezoelectric transducers based on periodically poled ferroelectric domains on lithium niobate bonded on silicon. The fabrication of the periodically poled transducers operating in the range 50-500 MHz has been achieved on a 3" 500 mum thick wafer. These devices have then been bonded on a silicon wafer and thinned to a few ten microns thick. Guided elliptic as well as partially guided longitudinal modes are excited, yielding phase velocity of about 3800 and 7000 m.s <sup xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">-1</sup> respectively. The experimental responses of the tested devices are compared to predicted harmonic admittances, showing a good agreement between both results and allowing for a reliable analysis of the nature of the excited modes.
Audio-Visual Data Skimming for E-Learning Applications (2008)

Using multimedia documents for learning puts specific demands on the user interface. Users want to be able to quickly skim audio-visual data in order to locate relevant information, skip parts of minor interest, reset replay to interesting positions, etc. In this paper we propose a new interface design which extends common media player interfaces by offering a new way for interactive, synchronised audiovisual data browsing. This approach allows users to skim multimedia documents at arbitrary speed and granularity levels with immediate visual and acoustic feedback.

Dynamic granular locking approach to phantom protection in R-trees (2002)

Over the last decade (1988-98), the R tree has emerged as one of the most robust multidimensional access methods. However, before the R tree can be integrated as an access method to a commercial strength database management system, efficient techniques to provide transactional access to data via R trees need to be developed. Concurrent access to data through a multidimensional data structure introduces the problem of protecting ranges specified in the retrieval from phantom insertions and deletions (the phantom problem). Existing approaches to phantom protection in B trees (namely, key range locking) cannot be applied to multidimensional data structures since they rely on a total order over the key space on which the B tree is designed. The paper presents a dynamic granular locking approach to phantom protection in R trees. To the best of our knowledge, the paper provides the first solution to the phantom problem in multidimensional access methods based on granular locking.
