Rollback propagation detection and performance evaluation of FTMR <sup>2</sup> M—a fault-tolerant multiprocessor (1982)

In this paper we consider the rollback propagation and the performance of a fault-tolerant multiprocessor with a rollback recovery mechanism (FTMR 2 M)[1], which was designed to be tolerant of hardware failure with minimum time overhead. Rollback propagation between cooperating processes is usually required to ensure correct recovery from failure. To minimize the waste of processor time and storage overhead required for handling sophisticated rollback propagations, the FTMR 2 M always keeps one recoverable state. Approaches for evaluating the recovery overhead and analyzing the performance of FTMR 2 M are presented. Two methods for detecting rollback propagations and multi-step rollbacks between cooperating processes are also proposed.
Indoor location tracking in non-line-of-sight environments using a IEEE 802.15.4a wireless network (2009)

Indoor location tracking of mobile robots or transport vehicles using wireless technology is attractive for many applications. IEEE 802.15.4a wireless networks offer an inexpensive facility for localizing mobile devices by time-based range measurements. The main problems of time-based range measurements in indoor environments are errors by multipath and non-line-of-sight (NLOS) signal propagation. This paper describes indoor tracking using range measurements and an Extended Kalman Filter with NLOS mitigation. The commercially available nanoLOC wireless network is utilized for range measurements. The paper presents experimental results of tracking a forklift truck in an industrial environment.
Inside SysML [UML 2.0 extensions for systems engineering] (2005)

This article details the unified modelling language which is extending its reach from software into the systems-engineering space. The SysML specification makes it possible to model both hardware and software in the same environment using extensions to this widely used software modelling language. The extensions that are being made to UML 2.0 will definitely help systems engineers to more adequately model their systems. Additionally, the work done by the SysML group has helped to highlight some deficiencies in UML 2.0, which are being addressed by that standard's finalisation task force. SysML remains a work in progress, so there may be further changes to watch.
Smart dynamic wavelength equalizer with on-chip spectrum analyzer (2000)

A fully automated dynamic wavelength equalizer with fast feedback is presented, consisting of a planar optical circuit made in silica and a minimal amount of secondary elements. An on-chip monitor and a single optical diode serve as a low-cost, fast, built-in optical spectrum analyzer used to feedback control the device. The system is demonstrated by flattening the amplified spontaneous emission spectrum of an erbium-doped fiber amplifier from 4.0 dB to within 0.55 dB peak-to-peak in less than a second.
Enhanced anaerobic benzene degradation with the addition of sulfate (1998)

Abstract Potential mechanisms for stimulating anaerobic benzene degradation in methanogenic sediments from a petroleum‐contaminated aquifer were evaluated. In short‐term (<2 weeks) incubations, addition of sulfate slightly stimulated benzene degradation and caused a small decrease in the ratio of methane to carbon dioxide production from benzene. However, in longer‐term (>100 days) incubations, sulfate significantly stimulated benzene degradation with a complete shift to carbon dioxide as the end product of benzene degradation. The addition of Fe(III) and humic substances had short‐term and long‐term effects that were similar to the effects of the sulfate amendments. In studies in which anaerobic groundwater was pumped through columns of aquifer sediments, addition of sulfate to the groundwater significantly enhanced the removal of benzene from the groundwater. The stoichiometry of sulfate and benzene removal from the groundwater passing through the sediment columns was consistent with benzene oxidation to carbon dioxide with sulfate serving as the primary electron acceptor. These results demonstrate for the first time that addition of sulfate may be an effective strategy for enhancing anaerobic benzene removal in some petroleum‐contaminated aquifers.
Measurement of Homocysteine and Other Aminothiols in Plasma: Advantages of Using Tris(2-carboxyethyl)phosphine as Reductant Compared with Tri-n-butylphosphine (2001)

The agreement between the TCEP and TBP methods was considerably lower for the determination of tCys, tCys-Gly, and tGSH than for tHcy. For total-aminothiol determination, the TCEP method yields better reproducibility and is more robust than the TBP method.
Quality assurance measurements in departments of pathology and laboratory medicine. (1990)

Previously, characteristics of the quality assurance program in each department of pathology and laboratory medicine were the uniqueness of the monitors selected, the thresholds set for activity, and definitions of good performance. In 1989, members of the College of American Pathologists developed and implemented the first nationwide quality assurance program for pathology and laboratory medicine. This program, Q-Probes, has been expanded for 1990; after completion of planning under way for 1991, indicators will be in place for all steps in the total testing process. More than 1100 institutions had subscribed by the first quarter of 1990. Input forms for measurements of clinical indicators of quality are distributed to participants and, after completion, submitted to a central computer facility where keypunching and data manipulations occur. The interpretation of results is enhanced by peer comparisons of the participant data collected. In many circumstances studied, a large proportion of the data are aggregated at extreme ends of the distribution. Because data distributions are nongaussian for the indicators studied, it is recommended that peer comparisons use the 10% to 90% range and that the central tendency be described as the median. Despite large databases for some indicators that exceed by more than 10- to 100-fold those previously reported, extensive categorization may preclude percentile ranking of participants. Critiques are distributed describing practices and suggestions for improvement. Steady improvement of each participant and of nationwide practice patterns are documented by remeasurements.
Characterization of a mixed MRSA/MRSE biofilm in an explanted total ankle arthroplasty (2011)

Bacterial biofilms have been observed in many prosthesis-related infections, and this mode of growth renders the infection both difficult to treat and especially difficult to detect and diagnose using standard culture methods. We (1) tested a novel coupled PCR-mass spectrometric (PCR-MS) assay (the Ibis T5000) on an ankle arthroplasty that was culture negative on preoperative aspiration and then (2) confirmed that the Ibis assay had in fact detected a viable multispecies biofilm by further micrographic and molecular examinations, including confocal microscopy using Live/Dead stain, bacterial FISH, and reverse-transcriptase-PCR (RT-PCR) assay for bacterial mRNA. The Ibis technology detected Staphylococcus aureus, Staphylococcus epidermidis, and the methicillin resistance gene mecA in soft tissues associated with the explanted hardware. Viable S. aureus were confirmed using RT-PCR, and viable cocci in the biofilm configuration were detected microscopically on both tissue and hardware. Species-specific bacterial FISH confirmed a polymicrobial biofilm containing S. aureus. A novel culture method recovered S. aureus and S. epidermidis (both methicillin resistant) from the tibial metal component. These observations suggest that molecular methods, particularly the new Ibis methodology, may be a useful adjunct to routine cultures in the detection of biofilm bacteria in prosthetic joint infection.

High-fidelity entanglement swapping with fully independent sources (2009)

Entanglement swapping allows one to establish entanglement between independent particles that never interacted or share any common past. This feature makes it an integral constituent of quantum repeaters. Here, we demonstrate entanglement swapping with time-synchronized independent sources with a fidelity that is high enough to violate a Clauser-Horne-Shimony-Holt inequality by more than four standard deviations. The fact that both entangled pairs are created by fully independent only electronically connected sources ensures that this technique is suitable for future long-distance quantum communication experiments as well as for novel tests on the foundations of quantum physics.
2-Chloro-4,6-dimethoxy-1,3,5-triazine. A New Coupling Reagent for Peptide Synthesis (1987)

In order to facilitate the purification of peptides, the new coupling reagent 2-chloro-4,6-dimethoxy-1,3,5-triazine (CDMT) is proposed. Due to the weakly basic properties of the triazine ring, the side products and excess coupling reagent are easily removed by washing the crude reaction product with diluted acids. CDMT enables the synthesis of di-,tri-, and pentapeptides in 75-98% yield under mild conditions and without concomitant racemization. Moreover, the reagent diminishes the formation of side products during the incorporation of serine with an unprotected hydroxy group or of N-protected ω-nitroarginine into the peptide chain.
Lefschetz operator and local Langlands mod $\ell$: The regular case (2012)

Let $p$ and $\\ell$ be two distinct primes. The aim of this paper is to show how, under a certain congruence hypothesis, the mod $\\ell$ cohomology complex of the Lubin-Tate tower, together with a natural Lefschetz operator, provides a geometric interpretation of Vignéras’s local Langlands correspondence modulo $\\ell$ for unipotent representations.
Monoclonal Antibody Targeting of the Cell Surface Molecule TM4SF5 Inhibits the Growth of Hepatocellular Carcinoma (2014)

The cell surface transmembrane receptor TM4SF5 has been implicated in hepatocellular carcinoma (HCC), but its candidacy as a therapeutic target has not been evaluated. Building on findings that immunization with a peptide vaccine targeting human TM4SF5 can exert prophylactic and therapeutic effects in a murine model of HCC, we developed a monoclonal antibody to characterize expression of TM4SF5 in HCC and to target its function there as an anticancer strategy. We found that the antibody modulated cell signaling in HCC cells in vitro, reducing cell motility, modulating E-cadherin expression, altering p27(kip1) localization, and increasing RhoA activity. Using a mouse xenograft model of human HCC, we documented the in vivo efficacy of the antibody, which suppressed tumor growth in either tumor prevention or treatment designs. Our work offers a preclinical proof of concept for TM4SF5 as a promising target for antibody therapeutics to treat HCC. Cancer Res; 74(14); 3844-56. ©2014 AACR.
Web Services for Service-Oriented Communication (Invited Paper) (2006)

Service-Oriented Communication (SOC) is a new development in the industry to enable communication through web services and SOA. SOC is to make communication as service and provide a service-oriented architecture to integrate communication in business applications. Recent advances of web service and SOA have made it possible for a full web service and SOA based communication paradigm over IP. This paper is an overview of the recent development in this area with a focus on key technologies that can be applied to web service enablement of communication. In particular, we discuss the generic web service based application session management based on WS-Session, the two-way full duplex web service interaction framework, and the development of Web Service Initiation Protocol (WIP). WIP is a full web service and SOA based communication protocol for multimedia and voice communication over IP. The generic web service approach of WIP overcomes many limitations which would be otherwise difficult to achieve in non-web service based communication methods used today. In addition, we discuss the service composition and orchestration framework based on WS- BPEL, and illustrate the application of this approach through some real use cases.

Improved performance from noncollinear pumping in a high-reflectivity Brillouin-enhanced four-wave mixing phase conjugator (1989)

A Brillouin-enhanced four-wave mixing conjugator having reflectivities in excess of 10/sup 6/ for probe inputs of less than 1 nJ is described. Improved performance is obtained by using a pumping geometry which minimizes beam distortion and is not precisely counterpropagating. When adjusted for maximum reflectance, output in the far field is exactly retroreflective with respect to the input. The output can be steered away from 180 degrees C without severe losses in performance by adjustment of the pumping geometry. Such behavior is consistent with a model based on the extended beam overlap geometry.< <ETX xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">></ETX>
Pipelined processor modeling with finite homogeneous discrete-time markov chain (1998)

The modeling of pipelined processor based on finite homogenous discrete-time Markov chain (FHDTMC) technique is investigated. A strong case is made, based on comparison between theoretical values and empirical data, that the processor pipeline is a memoryless system, with some limitations, and thus amenable to Markov chain modeling technique. A computer program, Markov chain analyzer (MCA), was implemented to test the concepts and feasibility of the FHDTMC modeling technique. The MCA is a dynamic instruction trace-driven processor pipeline and cache system simulator for modeling the pipelined processor as a FHDTMC. The MCA generates a single-step state transition probability (P) matrix, an approximation of limiting probability (A) matrix, the pipeline stage utilization factors, the clocks per instruction (CPI), and empirical data for establishing the memoryless property. The P matrix and A matrix are used as a starting point in analysis of the pipelined processor Markov chain.
Reducing the Discovery Overheads in a DHT Based P2P Network by Using Virtual Resources (2008)

Message delivery mechanism based on distributed hash table (DHT) can cause performance improvement over conventional P2P (peer-to-peer) system by increased delivery efficiency. However, the DHT, which is based on hash function, shows a few but important shortcomings: discovery of any resource without the same key value is not possible, and also repetitive discovery steps are required to discover resources with similar names. Therefore, in this research, we propose a simple but effective method which allows us to overcome those limitations of DHT method and to achieve performance enhancement. A virtual resource is not an actual resource, but a resource that acts like a wrapper to the original resources; it represents many similar resources and makes them discovered by a single discovery query. By using a virtual resource, users can obtain a significant improvement not only on performance but also on usability. Also experiment results show that using virtual resources can bring around 30% decrease in overall bandwidth usage and around 70% decrease in discovery time depending on given environment.
Application of cryobiopsy to morphological and immunohistochemical analyses of xenografted human lung cancer tissues and functional blood vessels (2008)

Cryobiopsy could be useful for histological examination of human tumors without morphological artifacts associated with IMDH. Furthermore, it allows direct examination of functional blood vessels and related signaling molecules, thereby providing a better evaluation of the human tumor microenvironment for clinical application.
Endogenous Opioids Participate in the Regulation of the Hypothalamic-Pituitary-Luteinizing Hormone Axis and Testosterone's Negative Feedback Control of Luteinizing Hormone* (1979)

Two narcotic antagonists, naloxone and naltrexone, significantly elevated serum LH levels in male rats within minutes after their sc injection. The peak increase in serum LH occurred 20 min after the injection. Naloxone increased LH levels up to a dose of 1 mg/kg, after which no further increases were found. A dose of 0.35 mg/kg produced a half-maximal response. The exogenous opioid morphine blocked the increase in LH produced by naloxone in a dose-dependent fashion, suggesting that the specific receptor-blocking effects of the antagonist could account for its enhancement of serum LH levels. The locus of action of naloxone within the hypothalamic-pituitary-LH axis appeared to be at the level of the hypothalamus since the drug had no effect on LHRH-stimulated release of LH by the anterior pituitary and did not block dihydrotestosterone's suppression of pituitary LH release in vitro. Naloxone also prevented testosterone's negative feedback inhibition of serum LH in the castrated male rat. The results of these studies suggest that endogenous opioids exist in brain tissue which normally inhibit activity in the hypothalamic-pituitary-LH axis and participate in the androgen-dependent feedback control of LH elaboration by this axis.
Identification of General Linear Relationships between Activation Energies and Enthalpy Changes for Dissociation Reactions at Surfaces (2003)

The activation energy to reaction is a key quantity that controls catalytic activity. Having used ab inito calculations to determine an extensive and broad ranging set of activation energies and enthalpy changes for surface-catalyzed reactions, we show that linear relationships exist between dissociation activation energies and enthalpy changes. Known in the literature as empirical Brønsted-Evans-Polanyi (BEP) relationships, we identify and discuss the physical origin of their presence in heterogeneous catalysis. The key implication is that merely from knowledge of adsorption energies the barriers to catalytic elementary reaction steps can be estimated.
Expression of a cloned rat histamine H2 receptor mediating inhibition of arachidonate release and activation of cAMP accumulation. (1992)

A DNA, cloned after screening a rat genomic bank with probes derived from the sequence of a putative dog histamine H2 receptor [Gantz, I., Schäffer, M., Delvalle, J., Logsdon, C., Campbell, V., Uhler, M. & Yamada, T. (1991) Proc. Natl. Acad. Sci. USA 88, 429-433], was used to prepare a probe for Northern blot analysis and to transfect Chinese hamster ovary (CHO) cells. Distribution of the gene transcripts in guinea pig tissues was consistent with that of H2 receptors. Transfected CHO cells expressed a high density of sites binding [125I]iodoaminopotentidine, a selective H2-receptor ligand. These sites were characterized as typical H2 receptors by using a series of competing agents that displayed apparent dissociation constants closely similar to corresponding values at a reference biological system. In transfected cells, histamine stimulated, with high potency and large receptor reserve, the accumulation of cAMP. In addition, in the same cells, histamine potently inhibited the release of arachidonic acid induced either by stimulation of constitutive purinergic receptors or by application of a Ca2+ ionophore. This inhibition was independent of either cAMP or Ca2+ levels. The results suggest that a single H2 receptor may be linked not only to adenylyl cyclase activation but also to reduction of phospholipase A2 activity. Because H1 receptors have been reported to stimulate arachidonic acid release, inhibition of this release, an unexpected signaling pathway for H2 receptors, may account for the opposing physiological responses elicited in many tissues by stimulation of these two receptors subtypes.
Predicting hospital admission at emergency department triage using machine learning (2018)

Machine learning can robustly predict hospital admission using triage information and patient history. The addition of historical information improves predictive performance significantly compared to using triage information alone, highlighting the need to incorporate these variables into prediction models.
