Rapid prototyping environment for the specification and automatic synthesis of controllers for interconnection routers (2002)

We consider the problem of rapidly prototyping policy-specific controllers for routers in interconnection networks. A routing controller obtains data (e.g. headers of messages) from functionality-specific components (e.g. routers, network/bus interfaces) extracts relevant information and sends data or control information to external components. Policy specific decisions regarding routing or backtracking are also implemented by the controller. We are developing CoDeL (controller description language) a hardware description language for designing sequential machines with special attention being paid to the data abstraction and data movement capabilities. The compiler produces synthesizable VHDL code which can be directly mapped to any given technology such as FPGA, ASIC etc.
Detection of Methicillin/Oxacillin Resistance and Typing in Aminoglycoside-Susceptible Methicillin-Resistant and Kanamycin-Tobramycin-Resistant Methicillin-Susceptible <i>Staphylococcus aureus</i> (2006)

Eighty-five atypical isolates of Staphylococcus aureus divided into 73 aminoglycoside-susceptible methicillinresistant (AS-MRSA) and 12 kanamycin-tobramycin-resistant methicillin-susceptible (KTR-MSSA) were phenotypically and genotypically examined for methicillin resistance. Among these tests, the diffusion method using the oxacillin and cefoxitin disks on Mueller-Hinton agar with and without NaCl, the incubation at 35 degrees C or 30 degrees C for 24 or 48 hr, respectively, and the determination of oxacillin MICs by E-test were performed. We also examined the presence of the mecA gene by PCR and its product PBP 2a by the Slidex MRSA Detection test after induction by cefoxitin disk. All of the AS-MRSA strains (100%) were detected by the cefoxitin disk in all conditions and by the oxacillin disk on Mueller-Hinton agar with 2% of NaCl at 35 degrees C. Without NaCl, the sensitivity fell to 97.2% by oxacillin disk. The oxacillin MICs for these isolates ranged from 2 to 128 mg/L. The mecA gene determinant and its product PBP 2a were detected in all AS-MRSA strains. All KTR-MSSA strains were phenotypically methicillin-susceptible and oxacillin MICs were below or borderline of breakpoint (< or =2 mg/L). The mecA gene determinant and its product were detected in one strain. Pulsed-field gel electrophoresis (PFGE) was applied and revealed the presence of two major patterns A (36.9%) and B (46.2%) in AS-MRSA isolates and seven patterns in the KTR-MSSA strains.
Chick embryo pancreatic transplants reverse experimental diabetes of rats. (1979)

The effectiveness of xenogeneic embryonic tissue in the treatment of experimental diabetes has been investigated in rats. The splenic lobes (80) of 15- to 18-d-old chick embryos, composed almost exclusively of endocrine tissue, were implanted directly into the hepatic parenchyma of the rat recipient. The biochemical and metabolic changes in the recipients suggest that embryonic transplants of 15-d-old chick pancreases were able to significantly improve, for a prolonged period of time (18 mo), the diabetic state of nonimmunosuppressed rats. None of the recipients of 18-d-old embryos splenic lobes exhibited a long-term improvement of the diabetic state after transplantation. The complete destruction of the pancreatic B cells of the recipients was assessed by: (a) immunocytochemical investigations of the recipient's pancreas, (b) measurement of insulin in the liver and pancreas of the recipients and (c) in situ vascular perfusion of their pancreas submitted to high glucose challenge. The results suggest that pancreatic tissue of the 15-d-old embryos is immunologically immature lacking one or several lymphocyte subsets implicated in the afferent lood of "non-self" recognition.
β-Amyloid Activates the O⨪2 Forming NADPH Oxidase in Microglia, Monocytes, and Neutrophils (1999)

The deposition of beta-amyloid in the brain is the key pathogenetic event in Alzheimer's disease. Among the various mechanisms proposed to explain the neurotoxicity of beta-amyloid deposits, a new one, recently identified in our and other laboratories, suggests that beta-amyloid is indirectly neurotoxic by activating microglia to produce toxic inflammatory mediators such as cytokines, nitric oxide, and oxygen free radicals. Three findings presented here support this mechanism, showing that beta-amyloid peptides (25-35), (1-39), and (1-42) activated the classical NADPH oxidase in rat primary culture of microglial cells and human phagocytes: 1) The exposure of the cells to beta-amyloid peptides stimulates the production of reactive oxygen intermediates; 2) the stimulation is associated with the assembly of the cytosolic components of NADPH oxidase on the plasma membrane, the process that corresponds to the activation of the enzyme; 3) neutrophils and monocytes of chronic granulomatous disease patients do not respond to beta-amyloid peptides with the stimulation of reactive oxygen intermediate production. Data are also presented that the activation of NADPH oxidase requires that beta-amyloid peptides be in fibrillary state, is inhibited by inhibitors of tyrosine kinases or phosphatidylinositol 3-kinase and by dibutyryl cyclic AMP, and is potentiated by interferon-gamma or tumor necrosis factor-alpha.
Treatment of antidepressant-induced sexual dysfunction (2003)

This article reviews the prevalence of antidepressant-induced sexual dysfunction and the strategies available for managing sexual adverse events. A high incidence of sexual dysfunction has been observed in patients treated with antidepressants. In particular, it has been reported in more than half of the patients treated with selective serotonin reuptake inhibitors. There are various pharmacotherapeutic strategies that can lead to reversal of sexual dysfunction. This article will review clinical studies on pharmacotherapeutic agents used to treat antidepressant-induced sexual dysfunction, as well as agents used to treat depression with a favorable sexual side-effect profile. Because sexual dysfunction can lead to treatment noncompliance and depression relapse, this is an issue that should be addressed by clinicians at initiation and throughout the course of treatment.
Developing Variation Aware Simulation Tools, Models, and Designs for STT-RAM (2018)

DEVELOPING VARIATION AWARE SIMULATION TOOLS, MODELS, AND DESIGNS FOR STT-RAM Enes Eken, PhD University of Pittsburgh, 2017 In recent years, we have been witnessing the rise of spin-transfer torque random access memory (STT-RAM) technology. There are a couple of reasons which explain why STT-RAM has attracted a great deal of attention. Although conventional memory technologies like SRAM, DRAM and Flash memories are commonly used in the modern computer industry, they have major shortcomings, such as high leakage current, high power consumption and volatility. Although these drawbacks could have been overlooked in the past, they have become major concerns. Its characteristics, including low-power consumption, fast read-write access time and non-volatility make STT-RAM a promising candidate to solve the problems of other memory technologies. However, like all other memory technologies, STT-RAM has some problems such as long switching time and large programming energy of Magnetic Tunneling Junction (MTJ) which are waiting to be solved. In order to solve these long switching time and large programming energy problems, Spin-Hall Effect (SHE) assisted STT-RAM structure (SHE-RAM) has been recently invented. In this work, I propose two possible SHE-RAM designs from the aspects of two different write access operations, namely, High Density SHE-RAM and Disturbance Free SHE-RAM, respectively. In addition to the SHE-RAM designs, I will also propose a simulation tool for STT-RAMs. As an early-stage modeling tool, NVSim has been widely adopted for simulations of emerging nonvolatile memory technologies in computer architecture research, including STT-RAM, ReRAM, PCM, etc. I will introduce a new member of NVSim family – NVSim-VXs, which enables statistical simulation of STT-RAM for write performance, errors, and energy consumption.
Oxidation-Reduction Potential – A Tool for Monitoring, Control and Optimization of Biological Nutrient Removal Systems (1985)

Oxidation-reduction potential (ORP) measurements were made in conjunction with monitoring of other process variables in biological nutrient removal systems to determine the suitability of using this parameter to monitor and characterize conditions in un-aerated bio-reactors. Results obtained over the course of a three year investigation indicate that ORP monitoring can provide a very meaningful indication of process and bio-reactor performance. Easy to make, ORP determinations are reliable and can be used to distinguish between different levels of respiratory activity and also to identify the onset on non-respiratory conditions. This has practical advantages in that it provides a rational basis for real time control and optimization of process nitrogen removal. In more highly anaerobic environments ORP was found to correlate with observed phosphorus release, thus providing a real time indication of this aspect of process performance. This investigation has concluded that ORP is a unique and very useful practical tool for process monitoring, control and optimization which holds great promise as a process control parameter in these and future applications, in particular as a sensor for continuous process monitoring and automated process control.

A parametric shape grammar that generates the ground plans of Palladio's villas is developed as a definition of the Palladian style. The grammar is applied to generate the plan for the Villa Malcontenta.
Voltammetric Characterization of a<i>N</i>,<i>N</i>‘-Diphenyl-<i>p</i>-phenylenediamine-Loaded Screen-Printed Electrode:  A Disposable Sensor for Hydrogen Sulfide (2003)

The voltammetric response of a 10% (by weight) N,N'-diphenyl-p-phenylenediamine (DPPD) and 90% (by weight) carbon and binder screen-printed electrode has been examined in aqueous media over a range of pH using cyclic voltammetry both in the presence and in the absence of sulfide. In the absence, the screen-printed electrode undergoes an initial oxidative process on the surface of the solid organic particles to form an insoluble layer of the corresponding cation radical salt, DPPD(*)(+)X(-), where X(-) is an anion present in the solution. The charge transfer is thought to occur at the three-phase boundary between solid DPPD, carbon, and the aqueous solution. At higher potentials, a second oxidative wave is observed that is attributed to the oxidation of the bulk DPPD with intercalation of the anion species present to form a solid phase of DPPD(*)(+)X(-). The two voltammetric processes were found to stabilize after repetitive scanning, after which time, sulfide was added to the solution. The voltammetric response was found to respond to sulfide by showing a decrease in both the oxidative and reductive waves, which can be attributed to the sulfide effectively blocking the three-phase boundary. The response was found to be independent of the electrode used and at pH 4 produced a linear range from 20 to 165 microM, and a limit of detection of 7.5 microM for sulfide detection was achieved.

Ultrawideband (UWB) Antennas With Multiresonant Split-Ring Loops (2009)

Novel ultrawideband (UWB) antennas with multiresonant split-ring loops and with coplanar waveguide (CPW) feed are presented in this communication. Dual concentric microstrip split-ring loops with different geometrical ground planes have been analyzed and compared. UWB antennas are designed, of which the dimension of each split-ring loop varies proportionally to the arithmetic progression sequence. The dimensions of the rectangular ground planes and the split-ring loops are tuned for achieving a very wide bandwidth. A tapered transmission line is adopted to improve the return loss performance in the required band. Measurement results show that the proposed UWB antennas have a wide bandwidth from 2 to 20 GHz, and the measured return losses are less than <i xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">-10</i> dB in this band combined with relative stable radiation characteristics.
RFID based localization techniques for indoor environment (2010)

In this paper, the Radio Frequency Identification (RFID) technology is used for indoor localization (i.e. location estimation). The location of a RFID reader is estimated based on the known locations of the RFID tags attached to the ceiling with 60 cm separation. Two arranged pattern of tags are considered. One is a square arranged pattern and another one is a triangle arranged pattern. Then, two simple location estimation methods are employed. The basic principle of location estimation for both methods is based on the average of the locations of detected tags observed by the reader. For the first estimation method, only maximum and minimum coordinates of detected tag are average. But for the second estimation method, all coordinates of detected tag are average. The effectiveness of tag arranged pattern and the location estimation methods is evaluated by the indoor experiment data. The results of the location estimated by both methods are compared. Also, the results of location estimation using the square and triangle arranged patterns are also shown. It is illustrated that the triangle arranged patterns gives better results than the square pattern in some certain. Moreover, the location estimations error for all observed locations for both methods are less than 30 cm. Furthermore, the average of the location estimation error for both methods is less than 15 cm. This is satisfied and applicable for some indoor applications.
Supercritical fluid extraction of fungal oil using CO<sub>2</sub>, N<sub>2</sub>O, CHF<sub>3</sub> and SF<sub>6</sub> (1990)

The extraction of oil from fungi ( Mortierella ramanniana var. angulispora ) was studied using carbon dioxide (CO 2 ), nitrous oxide (N 2 O), trifluoromethane (CHF 3 ) and sulfur hexafluoride (SF 6 ) under supercritical conditions. The oil solubility was highest in SC‐N 2 O followed by SC‐CO 2 , while both SC‐CHF 3 and SC‐SF 6 showed poorer solvent power. The recorded oil solubilities at 333 K and 24.5 MPa were 2.3 wt% in N 2 O, 0.48 wt% in CO 2 , 0.0099 wt% in CHF 3 and 0.0012 wt% in SF 6 . The oil solubilities in SC‐N 2 O and SC‐CO 2 were measured over the pressure range 15.7–29.4 MPa and at temperatures ranging from 313–353 K. N 2 O always showed greater solvent power than did CO 2 at the same temperature and pressure. The solvent power of a supercritical fluid increases with density at a given temperature, and increases with temperature at constant density. The change in neutral lipid composition of the extracted oil with the extraction ratio was measured. Free fatty acids or diglycerides were extracted more easily than triglycerides or sterol esters. The change in fatty acid composition was also measured. The proportion of γ‐linolenic acid in the extract remained constant throughout the extraction.

Objective To explore the changes of cellular and humoral immunity of local air passage or the whole body of asthmatics patients.Methods A total of 40 patients was divided into two groups.Control group was interfered by Seretide,Observation group was in the treatment of Seretide and BCG-PSN.At three observation points(baseline point,sudden temperature drop point,very cold temperature point) respectively,the levels of CD+3、CD+3CD+4、CD+3CD+8 and CD+4/CD+8 ratio in plasma and the levels of IgA、IgG and IgM in serum and induced sputum were detected.Results In both two groups,compared with the baseline point and very cold temperature point,the levels of CD+3 and CD+8 in plasma decreased significantly(P0.01),the levels of CD+4and CD+4/CD+8 increased significantly(P0.01) and the levels of IgA、IgG and IgM in serum and induced sputum decreased significantly(P0.01) at sudden temperature drop point.Compared with control group,the levels of CD+3and CD+8 in plasma increased significantly(P0.01),the levels of CD+4and CD+4/CD+8 decreased significantly(P0.01) and the levels of IgA、IgG and IgM in serum and induced sputum increased significantly(P0.01) in BCG-PSN group in the sudden temperature drop point.Conclusion The cellular and humoral immunity of patients with asthma are influenced by sudden temperature drop.Seretide plus BCG-PSN can enhance the immunity of patients with asthma,and improve the asthma induce by the descended immunity because of a sudden temperature drop.
Effect of RenaGel(R), a non-absorbed, calcium- and aluminium-free phosphate binder, on serum phosphorus, calcium, and intact parathyroid hormone in end-stage renal disease patients (1998)

RenaGel appears to be an effective phosphate binder free of calcium and aluminium. Phosphorus control with two to four RenaGel capsules per meal appears to result in comparable phosphorus lowering seen with calcium- or aluminium-based phosphate binders. RenaGel may offer an alternative for the control of phosphorus retention in end-stage renal disease patients.
Acoustic radiation from finite structures (1991)

Recently, the application of singular value decomposition has been discussed in identifying source modes of a radiating structure by providing a representation to the Neumann Green’s function for the far field of the structure. The source modes, identified as such, will form eigenstates of radiated power. The determination of such states is of significant interest in acoustics, having applications in radiation filtering and beaming. A different algorithm is introduced for the computation of the modes which does not require the application of singular value decomposition. Since eigenstates of radiated power are also eigenstates of the surface acoustic resistance, these modes may be computed by simply diagonalizing this operator which is real and symmetric. The eigenvalues computed will be proportional to the radiated power from each mode.
Efficient estimators for an HF radio link (1990)

A technique for the estimation of the sampled impulse response of an HF radio link was developed several years ago and was shown by computer simulation tests to have a substantial potential advantage in performance over more conventional systems. A number of further developments have led to new channel estimators. In some of these, a Kalman filter is incorporated into the system in such a way that the filter operates on only a few variable quantities and is therefore considerably less complex than a conventional Kalman filter. Three different Kalman filters are studied, two of these being designed for a channel varying linearly (at a constant rate) with time, and the third being a conventional Kalman filter that is designed for a time-invariant or very slowly time-varying channel. All of these employ an exponential window and therefore operate with a fading memory. A description is given of the various estimators, the results of a series of computer simulation tests are presented, and the accuracies of the channel estimates given by the different systems are compared.< <ETX xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">></ETX>
Temperature-dependent Expression of Flagella of Listeria manocytogenes Studied by Electron Microscopy, SDS-PAGE and Western Blotting (1988)

Washed cells of Listeria monocytogenes serotype 4b, grown in broth culture at 20 degrees C and at 37 degrees C, were examined by electron microscopy for the presence of flagella. Many flagella were seen in cells grown at 20 degrees C, whereas at 37 degrees C very few were expressed. Flagella sheared from the cell surface were partially purified by differential centrifugation. Using SDS-PAGE and Western blotting two distinct protein bands were seen in this preparation, both with an apparent molecular mass of approximately 29 kDa. Further purification of these proteins was achieved by gel filtration and ion-exchange chromatography. Whole organisms grown at 20 degrees C and 37 degrees C were examined in Western blots using an affinity-purified polyclonal antibody, and a monoclonal antibody, both directed against 29 kDa putative flagellin. Bacteria grown at 20 degrees C expressed abundant flagellin, whereas only trace amounts could be detected in organisms grown at 37 degrees C. It is concluded that organisms grown at 20 degrees C both produce and assemble flagellin at the cell surface, and that flagellin production is a less marked feature of organisms grown at 37 degrees C.

A potent antipeptic ulcer substance, acyclic diterpene alcohol, was isolated from a Thai medicinal plant identified with Croton sublyratus KURZ. The structure was determined by the spectral data and stereospecific synthesis to be (E, Z, E)-7-hydroxymethyl-3, 11, 15-trimethyl-2, 6, 10, 14-hexadecatetraen-1-ol.
Photoelastic Separation of Principal Stresses by Oblique Incidence (1943)

Abstract Rotation of a two-dimensional model about an axis in its plane is suggested as a simple and quite rapid means of obtaining p and q separately. A determination of retardation (fringe order) in an oblique position is all that is required in addition to the usual photoelastic measurements. Experimental and theoretical evidence is presented to show that accurate results can easily be obtained when the principal stress is of significant magnitude. The method can also be applied in three-dimensional studies.
