Stress Wave Propagation Effects in Two- and Three-Layered Composite Materials (2004)

Multilayer materials consisting of ceramic and glass/epoxy composites have been subjected to high strain rate compression testing using the Split Hopkinson Pressure Bar. The samples were extensively strain gaged so that dynamic data were generated directly from the samples during testing. Output data from the experiments were compared with numerical simulations of the same experiments and good agreement was noted. It was found that the stress distribution within samples was quite inhomogeneous and that stresses were highest in the region of the bar-sample interface. The presence of a rubber interlayer between the ceramic and glass/epoxy decreased the stress in both components but dramatically increased the degree of stress in homogeneity.
Intra-aortic balloon pump: indications and complications. (1998)

Results obtained with intra-aortic balloon pumps (IABPs) at Harbor-UCLA Medical Center from 1990 to 1995 were reviewed to analyze the indications for its use as well as the incidence and types of vascular complications that occurred. Of 86 patients (53 men and 33 women) in whom pumps were used, 66 underwent coronary bypass, 14 underwent valve replacement, and 6 underwent both coronary bypass/valve replacement. Thirteen (15%) deaths occurred (8 coronary bypass patients, 4 valve replacement patients, and 1 coronary bypass/valve replacement patient). The indications for IABP were broadly classified as prophylactic or inability to wean. Prophylactic IABP placement preoperatively occurred in 35 (41%) patients for profound ventricular dysfunction (27 patients), compelling coronary anatomy including critical left main disease (7 patients), and unstable angina (1 patient). Inability to wean occurred in 51 (59%) patients. Three patients (3.5%) developed major vascular complications resulting in limb ischemia. All three underwent thrombectomies, fasciotomies, and above-knee amputations; two patients subsequently died. Vascular reconstruction was performed in two patients as a direct result of their vascular process. All three vascular complications occurred in women. Besides gender, there was no difference between IABP patients with or without vascular complications in terms of age or presence of diabetes, hypertension, smoking history, obesity, or known peripheral vascular disease. These results indicate that IABPs are effective both prophylactically and intraoperatively in patients who would not otherwise survive cardiac surgery.
Sibutramine Produces Dose‐Related Weight Loss (1999)

Sibutramine administered once daily for 24 weeks in the weight loss phase of treatment for uncomplicated obesity produced dose-related weight loss and was well tolerated. Improvements in serum lipids and uric acid accompany sibutramine-induced weight loss. Most of the adverse events observed on sibutramine are related to its pharmacology, including small mean increases in blood pressure and heart rate.
MonONTO: A Domain Ontology for Network Monitoring and Recommendation for Advanced Internet Applications Users (2008)

In order to make recommendations to users about the potential performance of advanced Internet applications - in the scope of network monitoring - it is not sufficient to just analyze the network performance metrics: it should be also considered information concerning the application type, the traffic generated, and the user profile. In the present paper, we propose a new approach for monitoring the performance of advanced Internet applications based on the use of an expert system. The expert system will infer from a domain ontology named MonONTO. This ontology amasses the main concepts and their relationships in the following sub-domains: quality of service of advanced applications, network performance measurements, and user profiles. The knowledge base, originated from MonONTO, demonstrated its use and importance in the domain described here through axioms creation and inferences performed using a specific experimental rule engine.
Normal Conducting CW Transverse Crab Cavity For Producing Short Pulses In SPEAR3 (2017)

The ability to produce short pulse X-rays on the scale of 1-10 ps fwhm in the SPEAR3 storage ring light source would enable enhanced timing mode studies of dynamic processes in materials as they occur. The crab cavity approach appears to be optimal for SPEAR3 to produce short pulse X-rays. Furthermore, by using a two-frequency crabbing scheme, SPEAR3 would be able to produce short-pulse bunches while supplying the high average flux needed for regular users. While supercon-ducting RF (SCRF) technology could be a natural choice for the CW crab cavity, the deflecting voltage for SPEAR3 crabbing appears to be within reach of more affordable normal conducting RF (NCRF). In this paper, we present a preliminary NCRF CW crab cavity design for SPEAR3.
Productive nonlytic human immunodeficiency virus type 1 replication in a newly established human leukemia cell line. (1992)

We have isolated a lymphoid cell line, MDS, from the pleural exudate of a patient with chronic myelomonocytic leukemia. The cells are biphenotypic, containing various T-cell and myeloid markers, and are surface negative for CD4 and CD8 but have low CD4 mRNA. The cells grow in suspension with a doubling time of 15 hr, have been karyotyped as trisomy 21, are negative for human immunodeficiency virus type 1 (HIV-1), and are tumorigenic in the nude mouse. We have isolated two stable HIV-1-producing cell lines, MDS-T, by transfecting MDS cells with pHXBc2, and MDS-I, by infecting MDS cells with HIV-1IIIB. In 24 hr, 1 x 10(5) MDS-T or MDS-I cells produce 46 ng of p24 per ml and reverse transcriptase that is capable of incorporating 0.2 pmol of [32P]TTP into oligo(dT).poly(A). Ultrastructural studies showed numerous mature viral particles in MDS-T and MDS-I cells that are capable of infecting T cells. HIV-1 infection could be inhibited by 25% in the MDS cells with the anti-CD4 antibody Leu 3a. For over a year MDS-T and MDS-I cells have been producing high concentrations of HIV-1 in culture. A subclone derived from the MDS cells behaves like the parent cells when transfected or infected with HIV-1. In contrast to other T-cell lines, neither phorbol 12-myristate 13-acetate nor tumor necrosis factor alpha stimulated the replication of HIV-1, whereas bromoadenosine 3',5'-cyclic monophosphate or interferon alpha caused 50% and 80% inhibition of reverse transcriptase production, respectively. These chronically infected T-cell lines are a useful model system to study the effect of anti-HIV agents and cellular factors required for HIV-1 replication.
Noninvasive real-time imaging of apoptosis (2002)

Strict coordination of proliferation and programmed cell death (apoptosis) is essential for normal physiology. An imbalance in these two opposing processes results in various diseases including AIDS, neurodegenerative disorders, myelodysplastic syndromes, ischemiareperfusion injury, cancer, autoimmune disease, among others. Objective and quantitative noninvasive imaging of apoptosis would be a significant advance for rapid and dynamic screening as well as validation of experimental therapeutic agents. Here, we report the development of a recombinant luciferase reporter molecule that when expressed in mammalian cells has attenuated levels of reporter activity. In cells undergoing apoptosis, a caspase-3-specific cleavage of the recombinant product occurs, resulting in the restoration of luciferase activity that can be detected in living animals with bioluminescence imaging. The ability to image apoptosis noninvasively and dynamically over time provides an opportunity for high-throughput screening of proapoptotic and antiapoptotic compounds and for target validation in vivo in both cell lines and transgenic animals.
Scalable architectural support for trusted software (2010)

We present Bastion, a new hardware-software architecture for protecting security-critical software modules in an untrusted software stack. Our architecture is composed of enhanced microprocessor hardware and enhanced hypervisor software. Each trusted software module is provided with a secure, fine-grained memory compartment and its own secure persistent storage area. Bastion is the first architecture to provide direct hardware protection of the hypervisor from both software and physical attacks, before employing the hypervisor to provide the same protection to security-critical OS and application modules. Our implementation demonstrates the feasibility of bypassing an untrusted commodity OS to provide application security and shows better security with higher performance when compared to the Trusted Platform Module (TPM), the current industry state-of-the-art security chip. We provide a proof-of-concept implementation on the OpenSPARC platform.
Effects of Cations on the Volume and Elemental Composition of Nematocysts Isolated from Acontia of the Sea Anemone <i>Calliactis polypus</i> (1993)

The hypothesis that exchange of intracapsular divalent cations with Na+ in seawater increases the internal osmotic pressure during discharge of nematocysts of marine cnidarians was tested by examining effects of externally applied cations on the volume and elemental composition of nematocysts isolated from acontia of the sea anemone Calliactis polypus. The volume of isolated nematocysts increased with increasing concentrations of cations if the cation was monovalent but appeared to decrease if the cation was divalent. Ca2+ reduced the internal osmotic pressure of the nematocysts more efficiently than Mg2+. X-ray microanalysis of nematocysts incubated in 1 M solutions of various salts showed that Ca2+ in isolated nematocysts was only partially replaced, if at all, by externally applied Na+ and Mg2+ while most Mg2+ was replaced by Na+ and Ca+. The present results suggest that exchange of intracapsular divalent cations with external monovalent cations increases the internal osmotic pressure, and that selective binding of Ca2+ to polyanions in the capsule decreases it. Whether the increase in the internal osmotic pressure caused by the cation exchange is large enough to trigger discharge remains to be investigated.
Preparation, Bioactivity, and Drug Release of Hierarchical Nanoporous Bioactive Glass Ultrathin Fibers (2009)

Hierarchical nanoporous bioactive glass ultrathin fibers with different pore diameters from 1.5-nm micropores up to 65-nm macropores are synthesized using P123–PEO co-templates and an electrospinning technique (see image). Experiments demonstrate that the prepared bioactive glass fibers are highly homogenous and bioactive and their nanopores can control drug release well.

Computer-aided interpretation of ICU portable chest images: automated detection of endotracheal tubes (2008)

In intensive care units (ICU), endotracheal (ET) tubes are inserted to assist patients who may have difficulty breathing.
A malpositioned ET could lead to a collapsed lung, which is life threatening. The purpose of this study is to
develop a new method that automatically detects the positioning of ET tubes on portable chest X-ray images. The
method determines a region of interest (ROI) in the image and processes the raw image to provide edge enhancement for
further analysis. The search of ET tubes is performed within the ROI. The ROI is determined based upon the analysis of
the positions of the detected lung area and the spine in the image. Two feature images are generated: a Haar-like image
and an edge image. The Haar-like image is generated by applying a Haar-like template to the raw ROI or the enhanced
version of the raw ROI. The edge image is generated by applying a direction-specific edge detector. Both templates are
designed to represent the characteristics of the ET tubes. Thresholds are applied to the Haar-like image and the edge
image to detect initial candidates. Region growing, combined with curve fitting of the initial detected candidates, is
performed to detect the entire ET tube. The region or tube growing is guided by the fitted curve of the initial
candidates. Merging of the detected tubes after is performed to combine the detected broken tubes. Tubes
within a predefined space can be merged if they meet a set of criteria. Features, such as width, length of the detected
tubes, positions relative to the lung and spine, and the statistics from the analysis of the detected lines, are
extracted to remove the false-positive detections in the images. The method is trained and evaluated on two different
databases. Preliminary results show that computer-aided detection of tubes in portable chest X-ray images is promising.
It is expected that automated detection of ET tubes could lead to timely detection of malpositioned tubes, thus improve
overall patient care.
Purification and characterization of a thiol‐protease from <i>Bacteroides gingivalis</i> strain 381 (1987)

A protease from the culture supernatant of Bacteroides gingivalis 381, which hydrolyzes the chromogenic substrate Na-benzoyl-DL-arginine-p-nitroanilide (BAPNA), was partially purified by ammonium sulfate precipitation, gel filtration, and anion exchange chromatography. The molecular weight of this protease was determined by SDS-PAGE to be ca. 49,000. The optimum pH was around 7.6. The protease was stable at neutral pH and up to 40 degrees C. The isoelectric point was 4.9. The enzyme activity was enhanced by dithiothreitol, L-cysteine, and 2-mercaptoethanol and inhibited by p-chloromercuribenzoic acid, N-ethylmaleimide, and iodoacetic acid.
Partition and compose (2012)

Complex event processing uses patterns to detect composite events in streams of simple events. Typically, the events are logically partitioned by some key. For instance, the key can be the stock symbol in stock quotes, the author in tweets, the vehicle in transportation, or the patient in health-care. Composite event patterns often become meaningful only after partitioning. For instance, a pattern over stock quotes is typically meaningful over quotes for the same stock symbol. This paper proposes a pattern syntax and translation scheme organized around the notion of partitions. Besides making patterns meaningful, partitioning also benefits performance, since different keys can be processed in parallel. We have implemented partitioned parallel complex event processing as an extension to IBM's System S high-performance streaming platform. Our experiments with several benchmarks from finance and social media demonstrate processing speeds of up to 830,000 events per second, and substantial speedups for expensive patterns parallelized on multi-core machines as well as multi-machine clusters. Partitioning the event stream before detecting composite events makes event processing both more intuitive and parallel.
Active Botnet Probing to Identify Obscure Command and Control Channels (2009)

We consider the problem of identifying obscure chat-like botnet command and control (C & C) communications, which are indistinguishable from human-human communication using traditional signature-based techniques. Existing passive-behavior-based anomaly detection techniques are limited because they either require monitoring multiple bot-infected machines that belong to the same botnet or require extended monitoring times. In this paper, we explore the potential use of active botnet probing techniques in a network middle-box as a means to augment and complement existing passive botnet C & C detection strategies, especially for small botnets with obfuscated C & C content and infrequent C & C interactions. We present an algorithmic framework that uses hypothesis testing to separate botnet C & C dialogs from human-human conversations with desired accuracy and implement a prototype system called BotProbe. Experimental results on multiple real-world IRC bots demonstrate that our proposed active methods can successfully identify obscure and obfuscated botnet communications. A real-world user study on about one hundred participants also shows that the technique has a low false positive rate on human-human conversations. We discuss the limitations of BotProbe and hope this preliminary feasibility study on the use of active techniques in botnet research can inspire new thoughts and directions within the malware research community.
The need for a correct geological modelling support: the advent of the UVT-transform (2008)

Stanislas Jayr, Emmanuel Gringarten, Anne-Laure Tertois, Jean-Laurent Mallet and Jean-Claude Dulac of Paradigm* introduce a system for geological modelling support which allows the construction of geological structures, whatever their complexity, while honouring all available data. It is said to ensure a coherent mapping between the location of sediment particles today and their location in the original space of deposition, the parametric space.
Fabrication of Two-Layered Channel System with Embedded Electrodes to Measure Resistance Across Epithelial and Endothelial Barriers (2010)

This manuscript describes a straightforward fabrication process for embedding Ag/AgCl electrodes within a two-layer poly(dimethylsiloxane) (PDMS) microfluidic chip where an upper and a lower channel are separated by a semiporous membrane. This system allows for the reliable real-time measurement of transendothelial and transepithelial electrical resistance (TEER), an accepted quantification of cell monolayer integrity, across cells cultured on membranes inside the microchannels using impedance spectroscopy. The technique eliminates the need for costly or specialized microelectrode fabrication, enabling commercially available wire electrodes to easily be incorporated into PDMS microsystems for measuring TEER under microfluidic environments. The capability of measuring impedance across a confluent cell monolayer is confirmed using (i) brain-derived endothelial cells (bEND.3), (ii) Madin Darby Canine Kidney Cells (MDCK-2), and mouse myoblast (C2C12) (all from ATCC, Manassas, VA). TEER values as a function of cell type and cell culture time were measured and both agree with previously published values from macroscale culture techniques. This system opens new opportunities for conveniently resolving both transendothelial and transepithelial electrical resistance to monitor cell function in real-time in microfluidic cell cultures.
Caustic-Side Solvent Extraction Chemical and Physical Properties Progress in FY 2000 and FY 2001. (2002)

The purpose of this work was to provide chemical- and physical-property data addressing the technical risks of the Caustic-Side Solvent Extraction (CSSX) process as applied specifically to the removal of cesium from alkaline high-level salt waste stored at the US Department of Energy Savannah River Site. As part of the overall Salt Processing Project, this effort supported decision-making in regards to selecting a preferred technology among three alternatives: (1) CSSX, (2) nonelutable ion-exchange with an inorganic silicotitanate material and (3) precipitation with tetraphenylborate. High risks, innate to CSSX, that needed specific attention included: (1) chemical stability of the solvent matrix, (2) radiolytic stability of the solvent matrix, (3) proof-of-concept performance of the proposed process flowsheet with simulated waste, and (4) performance of the CSSX flowsheet with actual SRS high-level waste. This body of work directly addressed the chemical-stability risk and additionally provided supporting information that served to plan, carry out, and evaluate experiments conducted by other CSSX investigators addressing the other high risks. Information on cesium distribution in extraction, scrubbing, and stripping served as input for flowsheet design, provided a baseline for evaluating solvent performance under numerous stresses, and contributed to a broad understanding of the effects of expected process variables. In parallel, other measurements were directed toward learning how other system components distribute in the flowsheet. Such components include the solvent components themselves, constituents of the waste, and solvent-degradation products. Upon understanding which components influence flowsheet performance, it was then possible to address in a rational fashion how to clean up the solvent and maintain its stable function.
Decentralized Orchestration of Data-centric Workflows Using the Object Modeling System (2012)

Data-centric and service-oriented workflows are commonly used in scientific research to enable the composition and execution of complex analysis on distributed resources. Although there are a plethora of orchestration frameworks to implement workflows, most of them are not suitable to execute data-centric workflows. The main issue is transferring output of service invocations through a centralized orchestration engine to the next service in the workflow, which can be a bottleneck for the performance of a data-centric workflow. In this paper, we propose a flexible and lightweight workflow framework based on the Object Modeling Systems (OMS). Moreover, we take advantage of the OMS architecture to deploy and execute data-centric workflows in a decentralized manner to avoid passing through the centralized engine. The proposed framework is implemented in context of the Australian Urban Research Infrastructure Network (AURIN) project which is an initiative aiming to develop an e-Infrastructure supporting research in the urban and built environment research disciplines. Performance evaluation results using spatial data-centric workflows show that we can reduce 20% of the workflows execution time while using Cloud resources in the same network domain.
Optimum Mean-Square Decision Feedback Equalization (1973)

In this work we report new results relating to decision feedback equalization. The equalizer and the transmitting filter are optimized in a PAM data communication system operating over a linear noisy channel. We use a mean-square error criterion and impose an average power constraint at the transmitter. Assuming correct past decisions, an explicit formula for the minimum attainable mean-square error is given. The possible advantages of signaling faster than the Nyquist rate while decreasing the number of levels to maintain the same information rate are investigated. It is shown that, in all cases of practical interest, signaling faster than the Nyquist rate, while keeping fixed the information rate, increases the mean-square error. Finally, to illustrate the use of the results, application is made to a cable channel where the loss in dB varies as the square root of frequency. Various asymptotic formulas and curves are provided to exhibit the relationships between the quantities of interest.
