Peripheral artery atherectomy: description of technique and report of initial results. (1988)

Percutaneous transluminal atherectomy has been developed for treatment of peripheral artery stenoses. The atherectomy catheter is inserted through a sheath, and the resection window of the catheter is positioned adjacent to the vascular stenosis. The balloon is inflated, and the motor-driven cutting blade advanced. The balloon is then deflated, the catheter withdrawn, and the atheromatous material, which resembles the resected material of an endarterectomy, removed from the catheter. This process is repeated until the resection provides an adequate lumen. To date, 12 arterial lesions (three common iliac, two external iliac, four superficial femoral, and three popliteal artery) in ten patients have been resected with excellent angiographic results. The conditions of seven patients who underwent atherectomy for relief from claudication were improved by the criteria of ankle/arm ratios and/or claudication distance. Three patients successfully underwent atherectomy for limb salvage. More data on long-term patency and restenosis rates are needed before the ultimate role of atherectomy in the management of peripheral artery disease can be determined.
22 Renewal of conjunctival epithelium over amniotic membrane to perform autologous simple conjunctival epithelial transplantation (SCET): in vitro validation and results of clinical application for primary pterygium (2022)

We established the most suitable conditions for a novel strategy based on in vivo expansion of conjunctival cells from conjunctival fragments glued over the AM. The application of SCET seems to be effective and replicable for the renewal of conjunctiva in patients requiring ocular surface reconstruction.
MECHANICAL BEHAVIOR AND FATIGUE STUDIES OF RUBBER COMPONENTS USED IN TRACKED VEHICLES (2010)

&lt;title&gt;ABSTRACT&lt;/title&gt; &lt;p&gt;In this study, a styrene butadiene rubber, which is similar to the rubber used in road wheel backer pads of tracked vehicles, was investigated experimentally under monotonic and fatigue loading conditions. The monotonic loading response of the material was obtained under different stress states (compression and tension), strain rates (0.001/s to 3000/s), and temperatures (-5C to 50C). The experimental data showed that the material exhibited stress state, strain rate and temperature dependence. Fatigue loading behavior of the rubber was determined using a strain-life approach for R=0.5 loading conditions with varying strain amplitudes (25 to 43.75 percent) at a frequency of 2 Hz. Microstructural analysis of specimen fracture surfaces was performed using scanning electron microscopy and energy dispersive x-ray spectroscopy to determine the failure mechanisms of the material. The primary failure mechanisms for both loading conditions were found to be the debonding of particles on the order of 50 to 200 μm.&lt;/p&gt;
Power efficient integrated routing with reliability constraints in IP over WDM networks (2012)

The increasing trend of the power consumption of the Internet has attracted much attention of researchers from both academic and industrial communities. In this paper, we present a power efficient integrated routing algorithm for dynamic sub-lambda connections with reliability constraints in IP over WDM networks. Integrated routing which considers the IP layer as well as the optical layer together leads to better network resource utilization. An auxiliary graph is constructed by assigning the power consumption value as the weight of a link so as to capture the power consumption of a route. The algorithm tries to find a minimum power consumption path for a connection while satisfying the reliability requirements. Simulation results show the effectiveness of the algorithm in terms of power efficiency, blocking probability, and the average number of physical and virtual hops per connection goes through.
Construction of Unmarked Deletion Mutants in Mycobacteria (2008)

Site-specific recombinases such as the Saccharomyces cerevisiae Flp and the P1 phage Cre proteins have been increasingly used for the construction of unmarked deletions in bacteria. Both systems consist of an antibiotic resistance gene flanked by recognition sites in direct orientation and a curable plasmid for temporary expression of the respective recombinase gene. In this chapter, we describe strategies and methods of how to use sequence-specific recombination mediated by Flp and Cre to construct mutants of Mycobacterium smegmatis, Mycobacterium bovis BCG, and Mycobacterium tuberculosis.
Nickel-Decorated Graphene Oxide/Polyaniline Hybrid: A Robust and Highly Efficient Heterogeneous Catalyst for Hydrogenation of Terminal Alkynes (2015)

A polyaniline/graphene oxide composite was readily synthesized by liquid–liquid interface polymerization of aniline in the presence of a sulfonated graphene oxide suspension using hydrogen peroxide and iron(III) chloride as oxidants. Subsequently, nickel nanoparticles were decorated on the synthesized hybrid material and used for the hydrogenation of phenylacetylene and its derivatives at room temperature under 100 psi of hydrogen pressure. The synthesized hybrid catalyst showed excellent catalytic activity and was readily recovered by centrifugation at the end of the reaction. The recovered catalyst was successfully used for several runs without any significant loss in the catalytic activity. Importantly, no leaching was observed during this course.
Ground-penetrating radar survey and tracer observations at the West Pearl Queen carbon sequestration pilot site, New Mexico (2005)

The potential for leakage of injected CO2 at carbon sequestration sites is a significant concern in the design and deployment of long-term carbon sequestration efforts. Effective and reliable monitoring of near-surface environments in the vicinity of these sites is essential to ensure the viability of sequestration activities as well as long-term public and environmental safety. Identification of geologic features (such as faults, fracture zones, and solution enhanced joints that might facilitate release of injected CO2 back into the atmosphere) is a key step in this process. This study reports on near-surface geologic and geophysical characterization efforts conducted at the Department of Energy National Energy Technology Laboratory (NETL) West Pearl Queen carbon sequestration pilot site in southeastern New Mexico, USA, and their use for uncovering possible mechanisms associated with escape of small amounts of perfluorocarbon tracers injected with the CO2.
High-Yield Affinity Alkylation of the Atrial Natriuretic Factor Receptor Binding Site (1995)

To facilitate characterization of the atrial natriuretic factor (ANF) receptor, we have developed an affinity labeling procedure, stepwise affinity labeling, which allows specific labeling of ANF binding sites in adrenal plasma membranes at high yields. An iodoacetyl (IAc-), bromoacetyl (BrAc-), or maleimidobenzoyl group was attached to the amino-terminal alpha-amino group of the ANF(4-28) peptide, and the peptide derivatives were radioiodinated at Tyr-28 to obtain affinity reagents, N4alpha-IAc-[125I]ANF(4-28), N4alpha-BrAc-[125I]ANF(4-28), and N4alpha-(maleimidobenzoyl)-[125I]ANF(4-28). Receptor labeling was carried out in a stepwise fashion as follows: (1) Membranes were treated with p-chloromercuriobenzenesulfonic acid (PCMBS) or N-ethylmaleimide to block sulfhydryl groups; (2) the affinity reagent was allowed to bind to the receptor at 0 degrees C for 1 h; and (3) the membranes were washed to remove unbound reagent and were incubated at room temperature to effect alkylation reaction. Sodium dodecylsulfate (SDS)-polyacrylamide gel electrophoresis (PAGE) followed by autoradiography revealed specific labeling of a 130-kDa ANF receptor. On the basis of 125I-radioactivity incorporated, the labeling yields were estimated to be 70%, 52%, and 21% for the reactions with IAc-[125I]ANF(4-28), BrAc-[125I]ANF(4-28), and (maleimidobenzoyl)-[125I]ANF(4-28), respectively. The efficiency of receptor labeling by the stepwise procedure using IAc-[125I]ANF(4-28) was 27-fold greater than that obtained by photoaffinity labeling using N3Bz-[125I]ANF(4-28) and 63-fold greater than that by direct cross-linking using disuccinimidylsuberate and [125I]ANF(4-28) under comparable conditions. Digestion of the membrane protein labeled with IAc-[125I]ANF(4-28) by BrCN, endoproteinase Glu-C, and endoproteinase Lys-C gave single radiolabeled bands with apparent masses of 40, 18, and 29 kDa, respectively. Reversed-phase HPLC separation of the digests also gave single major peaks. The confinement of the affinity label to one major fragment in each digest suggests that the cross-linking occurred at a single or a limited number of sites. The stepwise affinity labeling with the high cross-linking yield and specificity may be useful for analyzing the ANF receptor binding site structure.
[Complex formation of single-stranded phage DNA with synthetic oligodeoxynucleotides and interaction of complexes with DNA-polymerase and restriction endonuclease]. (1986)

Hybridization of synthetic oligodeoxynucleotides with single-stranded phage M13mp2 DNA has been studied in terms of temperature, ionic strength, oligonucleotide molar excess and chain length, and DNA secondary structure. Combination of two decadeoxynucleotides corresponding to a nicked eicosamer (composite primer) was found to be efficient in the template-directed DNA polymerase-catalyzed chain elongation, where both decamers separately failed. Circular SS DNA was specifically linearized by BamHI cleavage of SS DNA-tetradecadeoxynucleotide duplex.

Secure Electronics Enabled by Atomically Thin and Photosensitive Two-Dimensional Memtransistors (2021)

The rapid proliferation of security compromised hardware in today's integrated circuit (IC) supply chain poses a global threat to the reliability of communication, computing, and control systems. While there have been significant advancements in detection and avoidance of security breaches, current top-down approaches are mostly inadequate, inefficient, often inconclusive, and resource extensive in time, energy, and cost, offering tremendous scope for innovation in this field. Here, we introduce an energy and area efficient non-von Neumann hardware platform providing comprehensive and bottom-up security solutions by exploiting inherent device-to-device variation, electrical programmability, and persistent photoconductivity demonstrated by atomically thin two-dimensional memtransistors. We realize diverse security primitives including physically unclonable function, anticounterfeit measures, intellectual property (IP) watermarking, and IC camouflaging to prevent false authentication, detect recycled and remarked ICs, protect IP theft, and stop reverse engineering of ICs.
Towards an integration of deep learning and neuroscience (2016)

Neuroscience has focused on the detailed implementation of computation, studying neural codes, dynamics and circuits. In machine learning, however, artificial neural networks tend to eschew precisely designed codes, dynamics or circuits in favor of brute force optimization of a cost function, often using simple and relatively uniform initial architectures. Two recent developments have emerged within machine learning that create an opportunity to connect these seemingly divergent perspectives. First, structured architectures are used, including dedicated systems for attention, recursion and various forms of short- and long-term memory storage. Second, cost functions and training procedures have become more complex and are varied across layers and over time. Here we think about the brain in terms of these ideas. We hypothesize that (1) the brain optimizes cost functions, (2) these cost functions are diverse and differ across brain locations and over development, and (3) optimization operates within a pre-structured architecture matched to the computational problems posed by behavior. Such a heterogeneously optimized system, enabled by a series of interacting cost functions, serves to make learning data-efficient and precisely targeted to the needs of the organism. We suggest directions by which neuroscience could seek to refine and test these hypotheses.
Dynamic agent systems in the CoAX Binni 2002 experiment (2003)

The goal of the intemational CoAX (Coalition Agents experiment) program was to demonstrate how agent systems could be used to provide agile andflexible command and control systems for coalition operations, and facilitate rapid integration of national C2 systems. The CoAX experiments modelled a coalition C4ISR system as a distributed, heterogeneous agent network using the DARPA CoABS (Control of Agent Based Systems) Grid infrastructure based on Java JINI technology. This paper outlines the CoAX Binni experiment which was held in October 2002 at the US Naval Warfare College, Newport RI. It describes the technology used in this experiment and the role of the ATI-ITUDE multi-agent architecture in the Australian componenr of the eqeriment. This involved logistics planning (and dynamic replanning) for a casualty evacuation from an Australian ship using BDI agents developed in the A~ITVDE architecture, and included interactions with Coalition medical and planning agents. Distributed agents were used to represent the various organisational entities involved in a simpl$ed logistics model, and agent interactions with the Coalition C4ISR system were mediated by human operators using I-X Process Panels. This provided a semi-autonomous system, where human approval initiated further autonomous interactions between Coalition and Australian agents.

Suppression of tumorigenicity of human prostate cancer cells by introduction of human chromosome del(12)(q13). (1994)

The introduction of normal chromosomes into tumor cells by microcell fusion-mediated transfer is a powerful technique to identify putative tumor suppressor genes. We have used this approach to independently transfer human chromosomes 3 and 12 into a human prostate cancer cell line, DU 145. We showed that while the extra copy of chromosome 3 had no effect on the in vivo tumorigenicity of these cells, microcell hybrids containing an introduced portion of chromosome 12 (12pter-12q13) exhibited complete suppression of tumorigenicity in athymic nude mice. The presence of a dual selectable marker facilitated the selection for cells having segregated del(12)(q13). Loss of this fragment in three different clones led to reexpression of the malignant phenotype. These results demonstrate that one or more genes on human chromosome 12 function as tumor suppressors of prostate carcinogenesis.

No $^{10}\mathrm{He}^{2+}$ ions were observed. The upper limit on the production rate of $^{10}\mathrm{He}$ is determined to be less than 3\ifmmode\times\else\texttimes\fi{}${10}^{\mathrm{\ensuremath{-}}5}$ that of $^{8}\mathrm{He}$.
Keratinocyte Detachment-Differentiation Connection Revisited, or Anoikis-Pityriasi Nexus Redux (2014)

Epidermis, a continuously self-renewing and differentiating organ, produces a protective stratum corneum that shields us from external chemical, physical and microbial threats. Epidermal differentiation is a multi-step process regulated by influences, some unknown, others insufficiently explored. Detachment of keratinocytes from the basement membrane is one such pro-differentiation stimulus. Here, we define the transcriptional changes during differentiation, especially those caused by detachment from the substratum. Using comprehensive transcriptional profiling, we revisited the effects of detachment as a differentiation signal to keratinocytes. We identified the genes regulated by detachment, the corresponding ontological categories and, using metaanalysis, compared the genes and categories to those regulated by other pro-differentiating stimuli. We identified 762 genes overexpressed in suspended keratinocyte, including known and novel differentiation markers, and 1427 in attached cells, including basal layer markers. Detachment induced epidermis development, cornification and desmosomal genes, but also innate immunity, proliferation inhibitors, transcription regulators and MAPKs; conversely the attached cells overexpressed cell cycle, anchoring, motility, splicing and mitochondrial genes, and both positive and negative regulators of apoptosis. Metaanalysis identified which detachment-regulated categories overlap with those induced by suprabasal location in vivo, by reaching confluency in vitro, and by inhibition of JUN kinases. Attached and in vivo basal cells shared overexpression of mitochondrial components. Interestingly, melanosome trafficking components were also overexpressed in the attached and in vivo basal keratinocytes. These results suggest that specific pro-differentiation signals induce specific features of the keratinization process, which are in vivo orchestrated into harmonious epidermal homeostasis.
Preventive congestion control based routing in ATM networks (2002)

Describes briefly a dynamic multi-path routing algorithm that has been considered for connection oriented asynchronous transfer mode (ATM) networks. The scheme takes advantage of cell multiplexing capability that has particular advantage in the network supporting the variable bit rate (VBR) traffic. The fundamental objective of the scheme is to propose a congestion control based scheme that bridges the gap between routing and congestion control as the network becomes congested. The proposed routing scheme works as a shortest path first algorithm under light traffic conditions. However as the shortest path becomes congested under unbalanced heavy traffic, the source uses multiple paths when and if available in order to distribute the calls and reduce cell loss. This mechanism will provide the clients for good quality of service within the given constraints. The authors compare the performance of the proposed scheme with the other competitive schemes. The throughput and cell loss performance are compared via simulations. These have been carried out concentrating on a 5 node network.< <ETX xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">&gt;</ETX>
Embedded neural network system for microorganisms growth analysis (2020)

This study presents autonomous system for microorganisms’ growth analysis in laboratory environment. As shown in previous research, laser speckle analysis allows detecting submicron changes of substrate with growing bacteria. By using neural networks for speckle analysis, it is possible to develop autonomous system, that can evaluate microorganisms’ growth by using cheap optics and electronics elements. System includes embedded processing module, CMOS camera, 670nm laser diode and optionally WiFi module for connecting to external image storage system. Due to small size, system could be fully placed in laboratory incubator with constant humidity and temperature. By using laser diode, Petri dish with microorganisms’ substrate is illuminated with speckle pattern. Embedded camera and processing system obtain images and stores them for processing with neural network. Neural network utilizes “3D ConvNets” architecture with ability to encode not only spatial speckle variance, but also their changes in time. Convolutive approach allows significantly reduce the number of trained parameters, therefore reducing training and detection time. Neural network training used 200 bacteria colonies and additional 300 areas without bacteria. In the result, trained neural network reaches 0.95 accuracy score, that proves correctness of the approach.
