Comparing the performance of stochastic simulation on GPUs and OpenMP (2013)

Since stochastic computing performs operations using streams of bits that represent probability values instead of deterministic values, it can tolerate a large number of failures in a noisy system. However, the simulation of a stochastic implementation is extremely time-consuming. In this paper, we investigate two approaches to speed up the stochastic simulation: a GPU-based simulation and an OpenMP-based simulation. To compare these two approaches, we start with several basic stochastic computing elements (SCEs) and then use the stochastic implementation of a frame difference-based image segmentation algorithm as case study to conduct extensive experiments. Measured results show that the GPU-based simulation with 448 processing elements can achieve up to 119x performance speedup compared to the single-threaded CPU simulation and 17x performance speedup over the OpenMP-based simulation with eight processor cores. In addition, we present several performance optimisations for the GPU-based simulation which significantly benefit the performance of stochastic simulation.

Lengthening of Below-the-Knee Amputation Stumps Using the Ilizarov Technique (1990)

Patients with short, traumatic, below-the-knee amputations (BKAs) frequently function as if they have knee disarticulations. The goal of this study was to evaluate the results in patients who had lengthening of their BKA stumps to improved prosthesis fit and increase ambulation. Three patients with traumatic BKAs, who were left with insufficient stumps for proper prosthesis wear, have had their stumps lengthened by Ilizarov's technique of distraction osteogenesis. The lengthening process produced a moderate degree of pain, and all patients had a temporary decrease in their range of motion. Two patients lost a substantial amount of gained length secondary to early full weight-bearing. Despite these difficulties, the procedure produced longer, more durable stumps in all patients with no final loss of knee range of motion.
Lipases: An Overview (2012)

Lipases are ubiquitous enzymes, widespread in nature. They were first isolated from bacteria in the early nineteenth century, and the associated research continuously increased due to the characteristics of these enzymes. This chapter reviews the main sources, structural properties, and industrial applications of these highly studied enzymes.
Precise Determination of Pair Interactions from Pair Statistics of Many-Body Systems In and Out of Equilibrium (2022)

The determination of the pair potential $v({\bf r})$ that accurately yields an equilibrium state at positive temperature $T$ with a prescribed pair correlation function $g_2({\bf r})$ or corresponding structure factor $S({\bf k})$ in $d$-dimensional Euclidean space $\mathbb{R}^d$ is an outstanding inverse statistical mechanics problem with far-reaching implications. Recently, Zhang and Torquato conjectured that any realizable $g_2({\bf r})$ or $S({\bf k})$ corresponding to a translationally invariant nonequilibrium system can be attained by a classical equilibrium ensemble involving only (up to) effective pair interactions. Testing this conjecture for nonequilibrium systems as well as for nontrivial equilibrium states requires improved inverse methodologies. We have devised a novel optimization algorithm to find effective pair potentials that correspond to pair statistics of general translationally invariant disordered many-body equilibrium or nonequilibrium systems at positive temperatures. This methodology utilizes a parameterized family of pointwise basis functions for the potential function whose initial form is informed by small- and large-distance behaviors dictated by statistical-mechanical theory. Subsequently, a nonlinear optimization technique is utilized to minimize an objective function that incorporates both the target pair correlation function $g_2({\bf r})$ and structure factor $S({\bf k})$ so that the small- and large-distance correlations are very accurately captured. To illustrate the versatility and power of our methodology, we accurately determine the effective pair interactions of the following four diverse target systems. We found that the optimized pair potentials generate corresponding pair statistics that accurately match their corresponding targets with total $L_2$-norm errors that are an order of magnitude smaller than that of previous methods.
Stable, Efficient, and All-Solution-Processed Quantum Dot Light-Emitting Diodes with Double-Sided Metal Oxide Nanoparticle Charge Transport Layers (2013)

An efficient and stable quantum dot light-emitting diode (QLED) with double-sided metal oxide (MO) nanoparticle (NP) charge transport layers is fabricated by utilizing the solution-processed tungsten oxide (WO3) and zinc oxide (ZnO) NPs as the hole and electron transport layers, respectively. Except for the electrodes, all other layers are deposited by a simple spin-coating method. The resulting MO NP-based QLEDs show excellent device performance, with a peak luminance of 21300 cd/m(2) at the emission wavelength of 516 nm, a maximal current efficiency of 4.4 cd/A, and a low turn-on voltage of 3 V. More importantly, with the efficient design of the device architecture, these devices exhibit a significant improvement in device stability and the operational lifetime of 95 h measured at room temperature can be almost 20-fold longer than that of the standard device.

High-performance glass-ceramic/copper multilayer substrate with thin-film redistribution (1992)

IBM has pioneered the use of large-area alumina multilayer ceramic substrates using state-of-the-art greensheet, molybdenum paste, and tooling technologies for its mainframe computers since 1980. During this time, a new generation of substrate materials have been developed based on copper metallization and a unique glass that crystallizes to cordierite (2Al <inf xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">2</inf> O <inf xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">3</inf> · 2MgO · 5SiO <inf xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">2</inf> ), which has a very low dielectric constant (5.0 compared to 9.4 in previous IBM systems). The glass-ceramic/copper system provides a factor of 3 improvement in electrical conductivity over alumina/molybdenum in previous IBM systems, and the number of metallized substrate layers has been increased from 45 to 63. The thermal expansion of the new substrate (30 ×10 <sup xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">−7</sup> °C <sup xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">−1</sup> ) is matched with that of the silicon chips, thereby enhancing the reliability of the 78,500 solder-bonded chip-to-substrate connections in the System/390®-Enterprise System/9000™ computers. Each substrate is 127.5 mm square and can support up to 121 complex logic and memory chips.

Simplified Ultrasonic Damage Detection in Fluid-Filled Pipes (2017)

The location and extent of damage in a pipe can be remotely determined from weld and internal damage reflections using a single acoustic emitter/sensor pair. The use of normalised reflections yields single numbers enabling long distance data collection techniques such as wireless hopping. The attenuation is twice as high for opposite inner and outer fluids (whether air and water, or water and air) as compared to identical inner and outer fluids. The absolute recorded signals in the water-filled pipe are attenuated by a factor two compared to the empty pipe. The axial length of detection is reduced by a half. The reduction of >90% in sensors and the longer axial detection (>10 $$\times $$ current state-of- the-art- technology) means that permanent fixed sensor pairs for whole pipelines are on the horizon of possibility. The greatest advantage is envisioned in submersed pipelines.
THE STABILITY IN WATER OF A NEW CHLORAMINE DISINFECTANT1 (1983)

ABSTRACT: The stability in water of a novel new chloramine agent, 3‐chloro‐4, 4‐dimethyl‐2‐oxazolidinone (agent I), which is an excellent water disinfectant, has been compared to the stabilities of several other water disinfectants. The agents tested in addition to agent I included N‐chlorosuccinimide, 2, 4‐dichloro‐5, 5‐dimethylhydantoin, tichloroisocyanuric acid, calcium hypochlorite, commercial grade HTH, and household bleach. The total chlorine content of a water solution of agent I in a demand free environment remains constant over a period of at least eight weeks, while that for all of the other agents declines markedly over that time period. An explanation for these observations will be offered. Prior work in these laboratories concerning use of agent I as a disinfectant for lake water in a laboratory scale treatment plant had shown that agent I has considerable potential for use as an alternative to chlorine gas for water disinfection.
Interleukin-8 and monocyte chemotactic protein-1 production by a human glioblastoma cell line, T98G in coculture with monocytes: involvement of monocyte-derived interleukin-1alpha. (1998)

We have previously demonstrated that a human glioblastoma cell line, T98G cells, produced high levels of interleukin-8 (IL-8) and monocyte chemotactic protein-1 (MCP-1) when stimulated with IL-1 or tumor necrosis factor-alpha (TNF-alpha). In this study, we found that T98G cells are capable of producing large amounts of IL-8 and MCP-1 when cocultured with human peripheral blood monocytes or a monocytic cell line, U937 cells. Since it is possible that both glioblastoma cells and monocytes are capable of producing chemokines, we determined which type of cells actually produced IL-8 and MCP-1, by the fixation of one or the other cell type with 3% paraformaldehyde (PA). This procedure revealed that T98G cells were the main source and that PA-treated monocytes effectively stimulated IL-8 and MCP-1 production by T98G cells. Both IL-8 and MCP-1 gene expression and protein production by T98G cells were confirmed by northern blot as well as immunohistochemical staining methods. To analyze the molecules on human monocytes responsible for inducing IL-8 and MCP-1 by T98G cells, several antibodies (Abs) as well as IL-1 receptor antagonist (IL-1Ra) were tested. Anti-IL-1alpha Ab and IL-1Ra almost completely abolished the IL-8/MCP-1-inducing capacity of the PA-fixed monocytes, while no inhibition was obtained with anti-IL-1beta, anti-TNF-alpha or Abs against CD11b/18, L-selectin or ICAM-1, indicating that membrane-associated IL-1alpha is involved in the IL-8/MCP-1 induction, while secreted IL-1alpha plays a major role in this cell-to-cell, i.e., juxtacrine interaction in unfixed conditions.
Visual Analysis of Geolocated Echo Chambers in Social Media (2017)

In news media, echo chambers refer to situations in which information is amplified or reinforced by communication and repetition. The characteristic of an echo chamber is, therefore, the absence of controversial discussions and a narrow set of opinions about a topic. We propose the use of Visual Analytics to describe spatiotemporal distributions of echo chambers using Twitter data, for specific geolocated events, such as concerts, strikes, demonstrations, etc. We analyze the echo chambers for Boston Marathon Bombing that took place on April 15, 2013. The social groups are displayed by a matrix view containing all connected components of the tweet mention graphs. To identify similar opinions, as well as, the diversity of topics in a discussion, we apply text classification and sentiment analysis. Lastly, we present initial findings based on real-world data.
Association analyses suggest GPR24 as a shared susceptibility gene for bipolar affective disorder and schizophrenia (2006)

Linkage analyses suggest that chromosome 22q12-13 may harbor a shared susceptibility locus for bipolar affective disorder (BPD) and schizophrenia (SZ). In a study of a sample from the Faeroe Islands we have previously reported association between both disorders and microsatellite markers in a 3.6 cM segment on 22q13. The present study investigated three candidate genes located in this segment: GPR24, ADSL, and ST13. Nine SNPs located in these genes and one microsatellite marker (D22S279) were applied in an association analysis of two samples: an extension of the previously analyzed Faeroese sample comprising 28 distantly related cases (17 BPD, 11 SZ subjects) and 44 controls, and a Scottish sample including 162 patients with BPD, 103 with SZ, and 200 controls. In both samples significant associations were observed in both disorders with predominantly GPR24 SNPs and haplotypes. In the Faeroese sample overall P-values of 0.0009, 0.0054, and 0.0023 were found for haplotypes in BPD, SZ, and combined cases, respectively, and in the Scottish sample overall P-values of 0.0003, 0.0005, and 0.016 were observed for similar groupings. Specific haplotypes showed associations with lowest P-values of 7 x 10(-5) and 0.0006 in the combined group of cases from the Faeroe Islands and Scotland, respectively. The G protein-coupled receptor 24 encoded by GPR24 binds melanin-concentrating hormone (MCH) and has been implicated with feeding behavior, energy metabolism, and regulation of stress and mood. To our knowledge this is the first study reporting association between GPR24 and BPD and SZ, suggesting that GPR24 variants may confer susceptibility to both disorders.

Review of the Electric Propulsion Space Experiment (ESEX) Program (2002)

The U.S. Air Force Research Laboratory’ s Electric Propulsion Space Experiment was launched and successfully operated on the Advanced Research and Global Observation Satellite, demonstrating the compatibility and readiness of high-power electric propulsion. This e ight was the culmination of an Air Force technology program to demonstrate the applicability of high-power electric propulsion for satellite applications. A brief history of the program is presented, followed by a description of the e ight operations, which successfully demonstrated the critical system components, the arcjet, power processor, and propellant feed system, verifying the interoperability of high-power electric propulsion with satellite operations. The two anomalies experienced during on-orbit operations, and their proposed causes, are also described.
System architecture and coexistence evaluation of licensed-assisted access LTE with IEEE 802.11 (2015)

Licensed-assisted access (LAA) is a new operation mode of Long-Term Evolution (LTE) in the unlicensed spectrum currently under study in the 3GPP standardization forum. In order to coexist with Wi-Fi, some of the new functionalities required of LAA LTE include a mechanism for clear channel assessment based on listen-before-talk (LBT), discontinuous transmission on a carrier with limited maximum transmission duration, and dynamic frequency selection (DFS) for radar avoidance in certain frequency bands. This paper presents a detailed overview of the impact of unlicensed spectrum operation on the LTE physical layer architecture, such as downlink physical channel design, scheduling, and radio resource management. System-level simulation results are then presented for indoor and outdoor scenarios, and show that fair coexistence between LAA and Wi-Fi can be achieved and that deployment of LAA can provide a boost in Wi-Fi performance.

Resource mobilization in developing Asia: Changing patterns and emerging issues (1994)

The article reviews characteristic patterns of domestic resource mobilization, investments and foreign capital inflows in developing Asia and identifies the emerging issues in resource mobilization. It finds that high levels of investments and savings have been an important reason that developing Asia has had better growth performance than other regions of the world. The pattern of resource mobilization has been different across countries depending upon their development stage. Low-income countries tend to rely on concessional official sources as their debt-servicing capacity is limited and their domestic resource mobilization capacity is weak, while higher income countries rely on domestic resource mobilization as well as competitive financing from international capital markets and foreign direct investment. Development challenges in Asia continue to be high in the 1990s and will require substantial resources. The challenges will in principle have to be met by domestic resources, indicating the need for strengthening the resource mobilization effort. However, the role of external resources will remain important because of limited domestic resource mobilization in developing Asia. Potential shortage in the global capital market implies that developing countries will have to improve their investment environment to induce more foreign private capital, including foreign direct investment. The possible shortage also indicates the need to strengthen the role of multilateral financial institutions.
Insulin receptor kinase following internalization in isolated rat adipocytes. (1987)

We have studied how insulin-mediated internalization of insulin receptors and insulin activation of the insulin receptor kinase might be inter-related. Isolated rat adipocytes were exposed to 0, 6, or 500 ng/ml insulin for 40 min at 37 degrees C. Subsequently, plasma membrane, low-density microsomal membrane and high-density microsomal membrane subcellular fractions were prepared. Measurement of insulin binding to insulin receptors isolated from the membrane fractions revealed that exposure of cells to insulin resulted in a loss of binding activity (13% at 6 ng/ml, 27% at 500 ng/ml insulin) from the plasma membranes which was completely accounted for by the appearance of receptors in the low-density and high-density microsomal membrane fractions, indicating that insulin had induced translocation of insulin receptors from the surface to the cell interior. Measurement of kinase activity of the isolated receptors revealed that exposure of intact cells to 500 ng/ml insulin resulted in as much as a 35-fold increase in the intrinsic kinase activity of receptors from subcellular fractions. The kinase activity per receptor was equal in all fractions at 3-4 min but by 20 min the activity of the internalized receptors fell approximately 40% to a steady state; plasma membrane receptors, on the other hand, remained fully active over time. This indicates that newly internalized receptors retain their kinase activity but undergo subsequent deactivation. Following exposure of cells to 6 ng/ml insulin, the degree of activation of the insulin receptor kinase was lower in the plasma membrane fraction (24% of the insulin effect at 500 ng/ml) than in the low-density and high-density microsomal membrane fractions (54 and 77%, respectively, of the insulin effect at 500 ng/ml). These results suggest that receptors with an activated kinase are preferentially internalized. We conclude that exposure of adipocytes to insulin causes endocytosis of insulin receptors and activation of insulin receptor kinase, newly internalized receptors are fully active tyrosine kinases but are deactivated as they traverse the intracellular organelles represented by low-density and high-density microsomal membranes, and insulin receptor occupancy, possibly by stimulating phosphorylation and activating the insulin receptor kinase, is important for targeting insulin receptors for internalization.
Optimization of Joint Equalization of High-Speed Signals using Bayesian Machine Learning (2021)

The paper elaborates an efficient algorithm for optimization of joint Feed-Forward Equalization (FFE) and Decision Feedback Equalization (DFE) for non-return-to-zero (NRZ) and 4 level pulse amplitude modulation (PAM-4) signals using Bayesian Machine Learning approach previously introduced for NRZ by authors and expanded for PAM-4. A new optimal covariant function and hyper-parameters has been selected for the Bayesian optimization. Cost function for the Bayesian optimization is chosen based on eye height. The proposed method was compared to the conventional Least Mean Square (LMS) method and showed significant improvement. Test cases were performed for several data rates of NRZ and PAM-4 signals with crosstalk and injected jitter. Test results show that the proposed algorithm is the more effective the higher data rates are considered.
