A new asynchronous pipeline scheme: application to the design of a self-timed ring divider (1996)

This paper describes an efficient means of synchronizing and pipelining asynchronous circuits implemented using differential cascode voltage switch logic (DCVSL) precharged function blocks. A modified version of this logic, called LDCVSL (latch differential cascode voltage switch logic), which is similar to the LCDL (latched CMOS differential logic), or DCVSL with NORA-latch, is used to improve the storage capability of the precharged function blocks. Improving the storage capability of the building blocks allows the design of an efficient pipeline scheme which is described in detail. Following a description of its potential performance, the pipeline scheme is applied to the design of self-timed rings. It is shown that more compact ring structures can be obtained without loss of performance. Our design methodology is then presented. It is based on the use of a private asynchronous standard cell library, fully compatible with an existing CMOS standard cell library provided by the foundry. Our approach allows the rapid design of standard cell based asynchronous circuits. Finally, both the pipeline scheme and design approach are illustrated through the design of a 32-b self-timed ring divider. The division algorithm is first briefly presented. The chip architecture is then described with the results obtained after fabrication. The test chip has been fabricated using the CNET/SGS-Thomson 0.5 /spl mu/m three metal layer technology. The 0.7 mm/sup 2/ chip computes 32-b divisions in 101 ns with a power consumption of 30 mW at a throughput of 10 million operations per second.

BST is a well established standard and testability framework for digital ICs and boards. The paper presents a test support IC controlled by an IEEE1149.1 interface, capable of providing access to analog nodes in mixed-signal boards. The proposed architecture (ABSINT - Analog to Boundary Scan Interface) is described and relevant implementation issues are discussed. A demonstrator IC implementing the ABSINT architecture is presented, and it is shown how it can be used to provide analog test channels under control of IEEE1149.1.< <ETX xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">></ETX>
Cyclic Voltammetry of Th(IV) in the Room-Temperature Ionic Liquid [Me<sub>3</sub>N<i><sup>n</sup></i>Bu][N(SO<sub>2</sub>CF<sub>3</sub>)<sub>2</sub>] (2006)

A Th(IV) compound, [Th(TFSI)4(HTFSI)].2H2O [where TFSI = N(SO2CF3)2], has been synthesized and characterized using elemental analysis, thermogravimetric analysis, and vibrational spectroscopy. The analysis suggests that the TFSI anion coordinates to the metal center via the sulfonyl oxygens as well as provides evidence for the coordination of HTFSI. The voltammetric behavior of this compound has been studied in the room-temperature ionic liquid [Me3NnBu][TFSI], and results show that Th(IV) is reduced to Th(0) in this ionic liquid in a single reduction step. Analysis of cyclic voltammograms shows that an insoluble product is being formed at the electrode surface, which is attributed to the formation of ThO2 by reaction with water. The E0 value for the reduction of Th(IV) to Th(0) has been determined to be -2.20 V (vs Fc+/Fc; -1.80 V vs SHE). A comparison of this E0 value with those obtained for Th(IV) reduction in a LiCl-KCl eutectic (400 degrees C), water, and nonaqueous solvents shows that the reduction in [Me3NnBu][TFSI] is easier to accomplish than that in these other solvents.
Urban Traffic Flow Forecast Based on FastGCRNN (2020)

Traffic forecasting is an important prerequisite for the application of intelligent transportation systems in urban traffic networks. The existing works adopted RNN and CNN/GCN, among which GCRN is the state-of-the-art work, to characterize the temporal and spatial correlation of traffic flows. However, it is hard to apply GCRN to the large-scale road networks due to high computational complexity. To address this problem, we propose abstracting the road network into a geometric graph and building a Fast Graph Convolution Recurrent Neural Network (FastGCRNN) to model the spatial-temporal dependencies of traffic flow. Specifically, we use FastGCN unit to efficiently capture the topological relationship between the roads and the surrounding roads in the graph with reducing the computational complexity through importance sampling, combine GRU unit to capture the temporal dependency of traffic flow, and embed the spatiotemporal features into Seq2Seq based on the Encoder-Decoder framework. Experiments on large-scale traffic data sets illustrate that the proposed method can greatly reduce computational complexity and memory consumption while maintaining relatively high accuracy.

A study on the frequency-domain Primary-ambient extraction for stereo audio signals (2014)

Primary-ambient extraction (PAE) has been playing an important role in spatial audio analysis-synthesis. Based on the spatial features, PAE decomposes a signal into primary and ambient components, which are then rendered separately. PAE is performed in subband domain for complex input signals having multiple point-like sound sources. However, the performance of PAE approaches and their key influences for such signals have not been well-studied so far. In this paper, we conducted a study on frequency-domain PAE using principal component analysis (PCA) in the case of multiple sources. We found that the partitioning of the frequency bins is very critical in PAE. Simulation results reveal that the proposed top-down adaptive partitioning method achieves superior performance as compared to the conventional partitioning methods.
Mechanisms of skeletal muscle atrophy (2006)

Although the precise role of the different muscle proteolytic machineries is still largely unknown, current studies are leading to new pharmacologic approaches that can be useful in blocking or partially preventing muscle wasting or improving muscle function in human patients.
High-Speed Magnetoresistive Random-Access Memory Random Number Generator Using Error-Correcting Code (2016)

A high-speed random number generator (RNG) circuit based on magnetoresistive random-access memory (MRAM) using an error-correcting code (ECC) post processing circuit is presented. ECC post processing increases the quality of randomness by increasing the entropy of random number. { We experimentally show that a small error-correcting capability circuit is sufficient for this post processing. It is shown that the ECC post processing circuit powerfully improves the quality of randomness with minimum overhead, ending up with high-speed random number generation. We also show that coupling with a linear feedback shift resistor is effective for improving randomness
Rotary mirror array for high-speed optical coherence tomography (2002)

We have developed a simple, high-speed, high-duty-cycle, linear optical delay line suitable for optical coherence tomography and optical Doppler tomography. Periodic longitudinal scanning is achieved by use of a tilted mirror array rotating at a constant speed. With a typical motor speed of 4000 rpm, our system has demonstrated a 2-mm axial scanning range, a 2400-Hz repetition rate, 94% duty cycle, and less than 0.1% nonlinear errors. Much higher repetition rates can be readily achieved by use of high-speed motors.

Allelic polymorphisms of human Fc gamma receptor IIA and Fc gamma receptor IIIB. Independent mechanisms for differences in human phagocyte function. (1992)

Two different allelic polymorphisms among the isoforms of human Fc gamma receptors have been defined: the low-responder (LR)-high-responder (HR) polymorphism of huFc gamma RIIA expressed on both PMN and monocytes and the NA1-NA2 polymorphism of the neutrophil Fc gamma RIII (huFc gamma RIIIB). To address the issues of whether the LR-HR polymorphism has a significant impact on Fc gamma R-mediated functions in human blood cells and whether any differences in LR-HR might be related to higher Fc gamma R-mediated phagocytosis in NA1 donors, we examined Fc gamma R-specific binding and internalization by donors homozygous for the two huFc gamma RIIA alleles. PMN from LR homozygotes showed consistently higher levels of internalization of erythrocytes opsonized with pooled human IgG (E-hIgG). The absence of an LR-HR phagocytic difference with erythrocytes opsonized with either anti-Fc gamma RIIA MAb IV.3 or rabbit IgG, as opposed to E-hIgG, suggested that the Fc piece of the opsonin might be important for this LR-HR difference. Accordingly, we studied HR and LR homozygotes with human IgG subclass-specific probes. Both PMN (independent of huFc gamma RIIIB phenotype) and monocytes from LR donors bound and internalized erythrocytes coated with human IgG2 (E-hIgG2) efficiently, whereas phagocytes from HR donors did so poorly. E-hIgG2 internalization was completely abrogated by blockade of the ligand binding site of huFc gamma RIIA with IV.3 Fab, indicating that huFc gamma RIIA is essential for the handling of hIgG2 and that the mechanism of the LR-HR phagocytic difference is at the level of ligand binding to huFc gamma RIIA. In contrast, the difference in internalization of E-hIgG between NA1 and NA2 homozygous donors was independent of the huFc gamma RIIA phenotype and did not manifest differences in ligand binding. Thus, the two known allelic polymorphisms of human Fc gamma R have distinct and independent mechanisms for altering receptor function, which may influence host defense and immune complex handling.
Polyurethane and carboxylated polysulfone blend ultrafiltration membranes. I. Preparation and characterization (2005)

Abstract Polysulfone was functionalized by carboxylation and blended with polyurethane (ether type). Blend membranes were prepared in the presence and absence of the additive poly(ethylene glycol) 600 and subjected to ultrafiltration characterizations such as compaction, pure water flux, water content, and hydraulic resistance. Morphological studies of the membranes were performed with scanning electron microscopy. The effects of the polymer composition and additive concentrations on the above parameters were analyzed and the results compared. © 2005 Wiley Periodicals, Inc. J Appl Polym Sci 97: 1307–1315, 2005
The Role of Eosinophils in Non-Parasitic Infections (2011)

Eosinophils are a subset of leukocytes traditionally associated with Th2-related diseases and helminth infections. However, accumulating evidence suggests eosinophils play a more prominent role in the immune response to bacterial and viral pathogens than previously realized. Specifically, eosinophils possess antimicrobial properties against a broad range of pathogens, and release specific and secondary granules as a result of pathogen recognition. Pathogen recognition is accomplished through expression of Toll-like receptors, as well as other surface and intracellular receptors expressed by the eosinophil. Interestingly, specific killing mechanisms employed by each granule protein differ based on pathogen recognition, but ultimately release of eosinophil granules leads to direct killing of many different pathogens. The precise mechanisms of killing by granule proteins and the circumstances in which specific proteins are secreted are only now being determined. Future efforts to understand these mechanisms may lead toward clinical use of granule proteins as antimicrobial agents in humans, in addition to revealing implications regarding the use of eosinophil-depleting therapies for allergic disorders. This review will summarize the literature to date regarding the role of eosinophils in non-parasitic infections.
Process for Solar Grade Silicon Production by Molten Salt Electrolysis Using Aluminum-Silicon Liquid Alloy (2011)

A new process for solar grade silicon production by molten salt electrolysis has been proposed and its feasibility discussed. This process consists of an electrolysis step of SiO2 dissolved in a fluoride melt using an aluminum-silicon liquid alloy cathode and a precipitation step of silicon from the liquid alloy. According to the calculation based on literature data, the proposed process has the possibility to produce solar grade silicon in combination with directional solidification, even if the electrolysis step has no purification effect. A preliminary electrolysis using aluminum cathode and carbon anode in a NaF-AlF3-SiO2 melt at 1273 K revealed that silicon was formed by the electrolysis and that sub-reactions, such as the reduction of SiO2 by aluminum and metal fog formation, also took place. Especially, SiO2 reduction by aluminum was found to be fast compared to the reduction by the electrolysis, which made it difficult to evaluate the current efficiency. Thus, these sub-reactions were further investigated in order to measure the reaction rates, and their potential dependence. Based on the obtained data, the cathodic current efficiency during the preliminary electrolysis was evaluated to be greater than 46%.
CoLab, Tools for Computer-Based Cooperation A Proposed Research Program (1984)

Since herpes simplex virus (HSV) can cause persistent infection of autonomic ganglia of both humans and experimentally infected animals, we followed the pattern of eye disease and viral growth after HSV inoculation of one superior cervical ganglion in rabbits. Of 27 inoculated animals, eye disease or detectable virus developed in 18. Anterior uveitis was the most common clinical manifestation (94%), but conjunctivitis and dendritic keratitis were also frequent (60%). All 12 uveal-retinal specimens tested and five of seven ipsilateral superior cervical ganglia had detectable virus. If recurrent herpetic iritis in humans is associated with persistent infection of the superior cervical ganglion, autonomic mediators might trigger episodes of virus shedding. In patients with herpetic iritis, then, the use of epinephrine and other adrenergic agonists or antagonists should be avoided.
Biochemical markers of bone turnover in paget's disease of bone (1999)

Although the measurement of total alkaline phosphatase activity in serum is a valid index to assess the activity of Paget's disease of bone and to monitor treatment efficacy, this marker may lack sensitivity in some cases. Among the various markers of bone formation and resorption that have been developed, serum bone specific alkaline phosphatase and procollagen I N-terminal peptide (PINP) for formation, urinary N-telopeptide (NTX) and alpha-C-telopeptide (CTX) for bone resorption have emerged as the most sensitive ones, and may be useful in the management of pagetic patients. We have recently shown that the beta-isomerization of type I collagen CTX is impaired in pagetic bone matrix characterized by the existence of woven bone, as compared to normal lamellar bone matrix. This abnormality results in a preferential urinary excretion of nonisomerized (alpha-CTX) over beta-isomerized (beta-CTX) that can be measured with specific immunoassays. Patients with active Paget's disease of bone are characterized by an abnormally high alpha/beta-CTX ratio which goes down to the normal range after bisphosphonate therapy, probably reflecting the lamellar structure of newly formed bone matrix in pagetic skeletal sites after treatment.
The design of electromagnetic pumps for liquid metals (1959)

The practical design of electromagnetic pumps is discussed with particular reference to construction of the duct/electrode element. Common features of electrical design are explained in terms of a simple theory of tube efficiency.The scope of d.c. pumps in meeting different duties and practical conditions is indicated. Some results of an experimental investigation of d.c. pump performance in a 4 in-diameter pipe loop are given. The significance of end current loss is indicated, and also the equivalent reduction effected by the presence of a graded fringing field in the end regions. A technique of electrode ‘wetting’ suitable for mercury and stainless steel is described, together with gas entrainment experiments.A homopolar generator with mercury collector rings is described. This type of machine would provide an efficient source of current for the d.c. pump. The newer types of rectifier are briefly compared with the generator for this application.Reference is made to polyphase travelling-field pumps, and their appropriate application is discussed. Simple theory of design is given, with relationships for optimum design at standard supply frequency.Other possible designs of large electromagnetic pump are briefly examined and compared with the basic forms of conduction and induction pump.The various classes of pump suitable for laboratory use are mentioned and general principles of selection are offered.

Regional tourism to regional transformation: the case of Jining area of Shandong Province in China (2012)

China is facing the urgent problem of transformation development and the rapid development of tourism at the same time. Regional tourism could be the stimulus and impetus for the transformational development of an area by rousing the vitality in various fields. Jining area of Shandong Province is an important coal energy base in China demanding transformation, as well as a traditional tourism area owing abundant tourism resources and development opportunities but with a lack of enough attention. It is proposed in this article that a regional wetland system could be established in the water area caused by coal field subsidence with the natural and culture resources in Jining area to develop regional tourism. Starting from this, the following will be realized gradually: ecological restoration, landscape reshaping, space integration, industrial restructuring and culture revival, and ultimately the comprehensive transformational development.
