Pyrolysis and Disposal of Mirex Residues (1978)

At the request of the Mississippi Imported Fire Ant Authority, methods were investigated for the disposal of shipment drums contaminated with mirex, 1,2,3,4,5,5,6,7,8,9,10,10 dodecachloropentacyclo [5.3.0.02,6.03,9.04,8] decane (I). Extensive chemical studies on mirex (1, 2, 3) showed that this compound is thermally stable and resistant to most common oxidizing and reducing systems. However, mirex has been shown to dechlorinate photochemically (4, 5, 6). Mirex has also been found to undergo reductive dechlorination in the presence of reduced hematin (7) and when incubated under anaerobic conditions with sewage sludge. McBee etal. (1) and Eaton etal. (2) have indicated mirex pyrolysis occurs only at temperatures above 500°. Holloman etal. (10) found that at 700° the major pyrolysis product of mirex was hexachlorobenzene. It was the object of this reseach to determine whether mirex residues in shipment containers could be reduced to acceptable levels by combinations of chemical extraction, chemical degradation,
Abstract 2346: Stenting of Pulmonary Artery Branch Stenosis Alleviates Pulmonary Valve Insufficiency in a Swine Model of Repaired Tetralogy of Fallot (2007)

Introduction : Pulmonary insufficiency-induced right ventricular volume overload in adults with repaired tetralogy of Fallot (TOF) is associated with reduced exercise tolerance, ventricular arrhythmias and sudden cardiac death. Studies have shown that the severity of pulmonary insufficiency (PI) predicts these symptoms. There has been indirect evidence that pulmonary artery branch stenosis (PABS) exacerbates PI in adults with repaired TOF. However the impact of treatment of PABS on PI has not been evaluated. Hypothesis : Relief of unilateral PABS in the setting of PI alleviates the severity of PI. Methods : Newborn piglets (n=9) underwent pulmonary valve resection with transannular patch and left pulmonary artery (LPA) banding. Between 10 to 16 weeks later, a cardiac catheterization was performed with hemodynamic evaluation and stenting of the banded LPA. Immediately prior to catheterization, and then 1 week following intervention, a cardiac MRI was performed. MRI data obtained included main and branch pulmonary arterial forward and reverse flow, and right and left ventricular volume. Results: Six animals survived the protocol. At time of catheterization, the LPA had a discrete stenosis, with a mean gradient of 11.6 mmHg (range 9 –16.1) across the banded region. The mean diameter of the LPA at the banded region was 3.4 mm (range 3.1– 4.2) and 10.8 mm distally (range 9.6 –14) at baseline, compared with a mean right pulmonary artery diameter of 20.2 mm. The banded region was stented to a mean diameter of 10.4 mm (range 8 –12.6). The main pulmonary artery regurgitant fraction (RF) at baseline was a mean of 38.2%; after stenting of the LPA, the RF decreased to 29.6% (p=0.02). Flow into the LPA improved in all animals, from a mean of 12.2% of total at baseline to 33.6% following stenting (p&lt;0.01). While the total RF decreased following LPA stenting, the branch pulmonary arterial RF did not change significantly for either pulmonary artery. Right ventricular volume did not change significantly after stenting of the LPA. Conclusions: In the setting of unilateral PABS, stenting alleviates the severity of PI in an animal model of repaired TOF. Though clinical studies are required, these findings should be considered in decisions regarding treatment of PABS after repair of TOF.
Impacts of Digital Media on Business (2015)

Modern media is no longer confined to a television or radio show, newspaper or advertisement. Instead, today's media-from text to video and sound-can be saved and shared electronically, using everything from desktop computers to small mobile devices. This electronic dissemination of media has had a powerful impact on the way people communicate for personal reasons, school and even business. However, digital media has not had only a positive impact on business. Through the history of internet, digital media has been developing in various ways. Here's we'll take a look at how it has affected the Internet and ways that it may be integrated moving forwards. One type of digital media is text; this in fact represented the very first explosion of this type of content out there on the Internet. When the Internet first got big, there was an explosion of content on the web, especially with all the text editors and word processing options out there today.

Fast switching of long-pitch cholesteric liquid crystal device (2011)

We propose a long-pitch cholesteric liquid crystal (ChLC) device capable of operation in both the dynamic mode and the memory mode. Fast switching between the homeotropic state and the focal conic state allows the display of moving pictures at a low operating voltage. In addition, we can write text messages on the proposed ChLC device by applying an external pressure locally to switch it from the focal conic state to the planar state.
Prospective assessment of subjective sleep benefit in Parkinson’s disease (2015)

We show that the subjective experience of SB in PD is not always related to an actual increase in reported motor function after sleep. Defining SB using either a symptom diary or a questionnaire on subjective experience, results in only partly overlapping groups. These data suggest that SB may be a more heterogeneous phenomenon than previously thought and that subjective experience of symptom severity is not necessarily related to actual motor function.
Topology discovery in PROFINET (2007)

PROFINET, an automation network based on Ethernet, includes the automatic discovery of the physical topology with the link layer discovery protocol (LLDP) in its newest specifications. In this paper we present the objectives of LLDP in PROFINET and general information about the protocol and other parts of IEEE 802.1AB, which describes LLDP. During the analysis of different implementations on the market, we found several problems of LLDP as well as issues with the interaction to a network management system. These are described in the later chapters.
15-Deoxy-Δ12,14-PGJ2 inhibits IL-6-induced Stat3 phosphorylation in lymphocytes (2005)

15-deoxy-delta(12,14)-PGJ(2)(15d-PGJ(2)) is a natural ligand that activates the peroxisome proliferators-activated receptor (PPAR) gamma, a member of nuclear receptor family implicated in regulation of lipid metabolism and adipocyte differentiation. Recent studies have shown that 15d-PGJ(2) is the potent anti-inflammatory agent functioning via PPARgamma-dependent and -independent mechanisms. Most postulated mechanisms for anti-inflammatory action of PPARgamma agonists are involved in inhibiting NF-kappaB signaling pathway. We examined the possibility that IL-6 signaling via the Jak-Stat pathway is modulated by 15d-PGJ(2) in lymphocytes and also examined whether the inhibition of IL-6 signaling is dependent of PPARgamma. 15d-PGJ(2) blocked IL-6 induced Stat1 and Stat3 activation in primary human lymphocytes, Jurkat cells and immortalized rheumatoid arthritis B cells. Inhibition of IL-6 signaling was induced rapidly within 15 min after treatment of 15d-PGJ(2). Other PPARgamma-agonists, such as troglitazone and ciglitazone, did not inhibit IL-6 signaling, indicating that 15d-PGJ(2) affect the IL-6-induced Jak-Stat signaling pathway via PPARgamma-independent mechanism. Although cycloheximide reversed 15d-PGJ(2)-mediated inhibition of Stat3 activation, actinomycin D had no effect on 15d-PGJ(2)-mediated inhibition of IL-6 signaling, indicating that inhibition of IL-6 signaling occur independent of de novo gene expression. These results show that 15d-PGJ(2) specifically inhibit Jak-Stat signaling pathway in lymphocytes, and suggest that 15d-PGJ(2) may regulate inflammatory reactions through the modulation of different signaling pathway other than NF-kappaB in lymphocytes.
Understanding Hydrogen Sulfide Storage: Probing Conditions for Sulfide Release from Hydrodisulfides (2014)

Hydrogen sulfide (H2S) is an important biological signaling agent that exerts action on numerous (patho)physiological processes. Once generated, H2S can be oxidized to generate reductant-labile sulfane sulfur pools, which include hydrodisulfides/persulfides. Despite the importance of hydrodisulfides in H2S storage and signaling, little is known about the physical properties or chemical reactivity of these compounds. We report here the synthesis, isolation, and characterization (NMR, IR, Raman, HRMS, X-ray) of a small-molecule hydrodisulfide and highlight its reactivity with reductants, nucleophiles, electrophiles, acids, and bases. Our experimental results establish that hydrodisulfides release H2S upon reduction and that deprotonation results in disproportionation to the parent thiol and S(0), thus providing a mechanism for transsulfuration in the sulfane sulfur pool.
An efficient scheduling mechanism using multiple thresholds for multimedia traffic in ATM switching nodes (2002)

We propose QLT/MT (Queue Length Threshold with Multiple Thresholds) as a dynamic priority cell scheduling mechanism to serve efficiently the multimedia traffic in ATM networks. The multimedia traffic can be categorized into three classes based on its real time properties and loss tolerance. QLT/MT is designed to schedule the traffic so that first served can be the most urgent class in terms of the priority of its class and the state of its queue. In the QLT/MT model, the cell scheduling relies on the number of cells in the queue of each class and its state determined by multiple thresholds. In order to evaluate our mechanism, the cell loss rate and average delay of QLT/MT are compared with those of the conventional mechanisms such as SPS, QLT, DQLT and DHOL. The simulation result shows that both the cell loss rate and average delay of QLT/MT measured for each class are lower in most cases than those of the other schemes.

Blanqueamiento interno de manchas graves por tetraciclina. Valoración clinica de cuatro años (1991)

Se trataron 258 dientes con manchas graves por tetraciclina mediante una tecnica de blanqueamiento interno. Se requeria con anterioridad al blanqueamiento tratamiento endodontico de todos los dientes. La evaluacion clinica y radiologica a los 4 anos revelo excelentes resultados esteticos en todos los pacientes. Los tratamientos endodonticos se consideraron satisfactorios, y ningun paciente mostro reabsorcion cervical externa despues de 4 anos. Este tipo de tratamiento constituye una alternativa valida a las carillas de porcelana para aquellos dientes que presentan manchas graves por tetraciclinas en los que el esmalte dentario y la corona anatomica estan intactos.
Optimal Metastability-Containing Sorting Networks (2018)

When setup/hold times of bistable elements are violated, they may become metastable, i.e., enter a transient state that is neither digital 0 nor 1. In general, metastability cannot be avoided, a problem that manifests whenever taking discrete measurements of analog values. Metastability of the output then reflects uncertainty as to whether a measurement should be rounded up or down to the next possible measurement outcome. Surprisingly, Lenzen and Medina (ASYNC 2016) showed that metastability can be contained, i.e., measurement values can be correctly sorted without resolving metastability first. However, both their work and the state of the art by Bund et al. (DATE 2017) leave open whether such a solution can be as small and fast as standard sorting networks. We show that this is indeed possible, by providing a circuit that sorts Gray code inputs (possibly containing a metastable bit) and has asymptotically optimal depth and size. Concretely, for 10-channel sorting networks and 16-bit wide inputs, we improve by 48.46% in delay and by 71.58% in area over Bund et al. Our simulations indicate that straightforward transistor-level optimization is likely to result in performance on par with standard (non-containing) solutions.
The potential for using thread-level data speculation to facilitate automatic parallelization (2002)

As we look to the future, and the prospect of a billion transistors on a chip, it seems inevitable that microprocessors will exploit having multiple parallel threads. To achieve the full potential of these "single-chip multiprocessors", however, we must find a way to parallelize non-numeric applications. Unfortunately, compilers have had little success in parallelizing non-numeric codes due to their complex access patterns. This paper explores the potential for using thread-level data speculation (TLDS) to overcome this limitation by allowing the compiler to view parallelization solely as a cost/benefit tradeoff rather than something which is likely to violate program correctness. Our experimental results demonstrate that with realistic compiler support, TLDS can offer significant program speedups. We also demonstrate that through modest hardware extensions, a generic single-chip multiprocessor could support TLDS by augmenting its cache coherence scheme to detect dependence violations, and by using the primary data caches to buffer speculative state.
FM-18 2130 Supervisory Control of Nondeterministic Systems Under Partial Observation * (1994)

In this paper we extend our earlier work on supervisory control of nondeterministic discrete event systems (DES) using prioritized synchronization as the control mechanism and trajectory model as the modeling formalism by considering design of supervisors un- der partial observation. We introduce the notion of obseruation- compatible systems and show that prioritized synchronous compo- sition of observation-compatible systems can be used as a mech- anism of control of nondeterministic systems under partial obser- vation in presence of driven events. Conditions for the existence of a supervisor in the above setting are obtained. Although these conditions are similar to the standard conditions of controllability and observability found in literature, they are siginificantly dif- ferent, as they depend on the trajectory model of the plant as opposed to its language model.
T-cell receptor V beta haplotype and complement component C5 play no significant role for the resistance to collagen-induced arthritis in the SWR mouse. (1991)

The importance of T-cell receptor (TcR) V beta gene haplotype and complement component C5 deficiency for the resistance to collagen-induced arthritis (CIA) in the SWR mouse was studied. Firstly, the immune responses against heterologous and autologous type II collagen (CII) were compared between SWR mice and arthritis-susceptible and major histocompatibility complex (MHC)-identical DBA/1 mice. Secondly, F1 and F2 crosses were made between the two strains and studied for arthritis development, V beta gene usage and C5 presence. After immunization with heterologous rat CII, both strains reacted with a strong autoantibody response. Immunization with mouse CII, on the other hand, gave a much lower response in both strains, with DBA/1 mice having the strongest response. A collection of B-cell hybridomas was created from the draining lymph nodes of SWR mice 9 days after immunization with rat CII. This hybridoma collection showed similarity to previous data from the DBA/1 mouse, by its high frequency of B cells producing IgG specific for CII and with a high degree of cross-reactivity with autologous mouse CII. After immunization with heterologous CII, both T cells specific for heterologous CII as well as T cells cross-reacting with autologous CII could be demonstrated. F1 crosses between SWR and DBA/1 were relatively resistant to CIA (8%), while in the F2 generation 72% of the mice developed arthritis. No correlation between V beta haplotype or C5 and development of arthritis in the F2 mice was found. It is concluded that the resistance to CIA in the SWR mouse is not related to either V beta haplotype or C5 deficiency. Instead we postulate the involvement of two or more genes which are important for the induction and maintenance of tolerance to own CII.

Edge reflection type SAW resonators on silicon substrate using ZnO thin films (2017)

In general surface acoustic wave (SAW) devices are made on piezoelectric substrates, hence difficult to integrate with circuits made on silicon. SAW devices can be realized on a silicon substrate using a film of piezoelectric material in conjunction with interdigital transducers (IDT) facilitating monolithic integration of SAW devices with circuits. Normally, SAW resonators consist of reflector gratings with large number of fingers to form standing waves and to confine SAW, and consume significant die area. The objective of the paper is to explore implementation of edge reflection (ER) type SAW devices, which are extremely compact, on silicon substrate.
Cerebellar dysfunction in essential tremor (2016)

The simplest explanation for the present results is that the cerebellum itself, including the Purkinje cells, is involved in essential tremor, which may reflect a primary pathogenic lesion or secondary compensatory physiological phenomenon to an original pathogenic lesion elsewhere. © 2016 International Parkinson and Movement Disorder Society.
Microwave characterization of intrinsically tunable FBARs (2012)

Unlike the traditional piezoelectric film (AlN, ZnO etc.) based FBARs, the experimental characterization of the tunable ferroelectric FBARs typically start with low frequency DC measurements. In this work wide band microwave measurements are used to generate DC dependent analytic approximations for the parameters of the BVD model. Mason's model and curve fitting procedure is used to extract the DC bias dependent acousto-electric material parameters of the ferroelectric films.
A Lightweight Authentication with Dynamic Batch-Based Group Key Management Using LSTM in VANET (2022)

Due to its complexity and mobility, VANET (vehicle ad hoc network) security has long plagued the development of the IoT industry. It is still a big challenge for users to decide the trustworthiness of an anonymous message or the preservation of personal information. Group signature is widely used in VANET anonymous authentication, but the existing solutions suffer from high computation costs in certificate revocation list (CRL) checking and signature verification process. In our scheme, we develop a lightweight protocol based on hashing functions and group keys, which escapes from the heavy computation cost. Then, we propose a dynamic batch-based group key distribution process, which is based on long short-term memory (LSTM) neural network to predict traffic flow and calculate the weight to determine the right time for key update. In this way, our method will significantly reduce computation delay and communication overhead. The security and performance analyses show that our scheme is more efficient in terms of authentication speed while keeping conditional privacy in VANET.
Improved Particle Size Control for the Dispersion Polymerization of Methyl methacrylate in Supercritical Carbon Dioxide (2016)

Dispersion polymerization is a well‐established method of producing polymer particles that are easily handled and processed. With careful choice of reaction conditions this technique can yield well defined, spherical particles for a wide range of applications. The use of supercritical carbon dioxide (scCO 2 ) as a reaction medium offers a route to performing these syntheses without excessive use of volatile organic solvents and minimizes work‐up and disposal steps. However a significant drawback has been the fact that up till now the control of particle size and morphology from CO 2 have been limited. This study presents control of particle size and morphology over an unprecedented range for a single stabilizer in scCO 2 by coordinating a few simple parameters to tailor the conditions toward different sizes. Further, this study introduces the novel approach in scCO 2 of using delayed monomer addition which allows considerable reduction of the batch‐to‐batch variability as well as reduced agglomeration between particles. image
Iron-based ferritin nanocore as a contrast agent (2010)

Self-assembling protein cages have been exploited as templates for nanoparticle synthesis. The ferritin molecule, a protein cage present in most living systems, stores excess soluble ferrous iron in the form of an insoluble ferric complex within its cavity. Magnetic nanocores formed by loading excess iron within an engineered ferritin from Archaeoglobus fulgidus (AfFtn-AA) were studied as a potential magnetic resonance (MR) imaging contrast agent. The self-assembly characteristics of the AfFtn-AA were investigated using dynamic light scattering technique and size exclusion chromatography. Homogeneous size distribution of the assembled nanoparticles was observed using transmission electron microscopy. The magnetic properties of iron-loaded AfFtn-AA were studied using vibrating sample magnetometry. Images obtained from a 3.0 T whole-body MRI scanner showed significant brightening of T(1) images and signal loss of T(2) images with increased concentrations of iron-loaded AfFtn-AA. The analysis of the MR image intensities showed extremely high R(2) values (5300 mM(-1) s(-1)) for the iron-loaded AfFtn-AA confirming its potential as a T(2) contrast agent.
