A novel low gate-count serializer topology with Multiplexer-Flip-Flops (2012)

This paper proposes Multiplexer-Flip-Flops (MUX-FFs) to be a high-throughput and low-cost solution for serial link transmitters. We also propose Multiplexer-Latches (MUX-Latches) that possess the logic function of combinational circuits and storing capacity of sequential circuits. Adopting the pipeline with MUX-FFs, which are composed of cascaded latches and MUX-Latches, many latch gates for sequencing can be removed. Analysis shows that an 8-to-1 serializer in the pipeline topology with MUX-FFs reduces 52% gate-count compared to the traditional pipeline topology. To verify the function of the proposed design, a chips is implemented with the proposed 8-to-1 serializer with MUX-FFs in 90 nm CMOS technology. The measured results show that the proposed serializer with MUX-FFs are bit-error-free (with BER <; 10 <sup xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">-12</sup> ), operating at up to 12 Gbit/s.
TSAO analogs. Stereospecific synthesis and anti-HIV-1 activity of 1-[2',5'-bis-O-(tert-butyldimethylsilyl)-.beta.-D-ribofuranosyl]-3'-spiro-5''-(4''-amino-1'',2''-oxathiole-2'',2''-dioxide)pyrimidine and pyrimidine-modified nucleosides (1992)

Several analogues of a new lead for anti-HIV-1 agents [1-[2',5'-bis-O-(tert-butyldimethylsilyl)-beta-D-ribofuranosyl]-thymine] -3'-spiro-5''-(4''-amino-1'',2''-oxathiole 2'',2''-dioxide) (TSAO) modified at positions N-3, O-4 and C-5 of the thymine moiety, have been prepared and evaluated as inhibitors of HIV-1 replication. A new stereoselective synthetic procedure is described. Reaction of 1,2-di-O-acetyl-5-O-benzoyl-3-C-cyano-3-O-mesyl-D-ribofuranose with pyrimidine bases, followed by treatment with Cs2CO3 afforded stereoselectively, beta-D-ribofuranosyl-3'-spiro nucleosides. 2',5'-O-Deacylation and subsequent treatment with tert-butyldimethylsilyl chloride gave the TSAO derivatives. Only those analogues having a tBDMSi group at both the C-5' and C-2' positions of the ribose moiety showed potent anti-HIV-1 activity. The activity ranged from 0.060 microM to 1.0 microM. Introduction of an alkyl or alkenyl function at N-3 of the thymine ring markedly decreased cytotoxicity without affecting the antiviral activity. While markedly active against HIV-1, the TSAO derivatives had no activity against HIV-2 or SIV. They represent the first example of nucleoside analogues with an intact ribose moiety that discriminate between HIV-1 and other retroviruses.
Study of Magnetic Field Measurement System for g-2/EDM Experiment at J-PARC (2016)

Two magnetic field monitoring systems for g-2/EDM experiment at J-PARC are developed. One is a continuous-wave NMR magnetometer, which is used to measure the field homogeneity in a muon storage region. The other is a Hall effect magnetometer, which is used to measure the magnetic field around the muon injection region and that for focusing the muon beam. In order to improve the accuracy of the commercial NMR magnetometer, a digital signal processing system was implemented instead of an analog one. As for the Hall probe system, a three-axis Helmholtz coil system was fabricated to measure tilt angles of Hall sensors in a three-axis Hall probe. The field homogeneity of each Helmholtz coil was measured, and the result agreed well with the design values.
POLYSULFONYLAMINE: TEIL XXXIV.1DIMESYLAMINOSULFONYLISOCYANAT: DARSTELLUNG, FESTKÖRPERSTRUKTUR UND ADDITIONSREAKTIONEN MIT ALKOHOLEN (1992)

Abstract The title compound (MeSO2)2N‒SO2‒NCO (1) is obtained from ClSO2NCO and AgN(SO2Me)2 in benzene. It is instantaneously and completely hydrolyzed by excess water to form CO2, NH4 +, SO4 2- and (MeSO2)2N−. The addition of alcohols to the isocyanate function of 1 leads to N-substituted urethanes (MeSO2)2‒NSO2‒NH‒C(O)OR with R = Me, Et or iPr. 1 crystallizes in the triclinic space group P1 with a = 532,4(3), b = 747,8(5), c = 1259,6(6) pm, α = 79,90(5), β = 86,30(5), γ = 77,49(5)°, V = 0,4818(3) nm3 (at -95°C), Z = 2. The bonding parameters and the conformational properties of the molecule are discussed and compared with those of the known electron-diffraction structure of Cl‒SO2‒NCO in the vapour phase.
Genomic analyses of microbial processes in biogeochemical cycles. (2006)

This chapter reviews the genomic and non-genomic approaches to the study of microbial processes in biogeochemical cycles in soil. The latest and most powerful technologies revolutionizing microbiology are based on genomics - the mapping and sequencing of genomes and analysis of gene and genome function. The significant advantages of genomic techniques over traditional methods are discussed. These molecular approaches are polymerase chain reaction (PCR) and reverse transcription PCR, fluorescence in situ hybridization, macroarray/microarray, stable isotope probing, and metagenomics. In addition, a comparison of these genomic techniques for the analysis of microbial processes in soil is given. Specific examples are cited in some detail to inform the selection of appropriate techniques and to evaluate the results generated by them.
Online-measurement systems for agricultural and industrial AD plants – A review and practice test (2014)

Online-measurement systems for AD plants in general are crucial to allow for detailed and comprehensive process monitoring and provide a basis for the development and practical application of process optimisation and control strategies. Nevertheless, the online measurement of key process variables such as Volatile Fatty Acids (VFA) and Total Alkalinity (TA) has proven to be difficult due to extreme process conditions. High Total Solids (TS) concentrations and extraneous material often damage the sensors or have a strong negative impact on measurement quality and long-term behaviour. Consequently, there is a need for new robust and accurate online-measurement systems. The purpose of this paper is to give an overview of existing online-measurement systems, to present the current state of research and to show the results of practice tests at an agricultural and industrial AD plant. It becomes obvious that a broad variety of measurement solutions have been developed over the past few years, but that the main problem is the upscaling from lab-scale to practical application at full-scale AD plants. Results from the practice tests show that an online-measurement of pH, ORP, TS is possible.

Chemotherapy and immunity in opportunistic parasitic infections in AIDS (1992)

Parasitic diseases are endemic in parts of the tropics, but there is no convincing evidence that their prevalence or incidence is increasing due to the HIV epidemic. Available scientific data on parasitic infections in patients with the Acquired Immunodeficiency Syndrome (AIDS) suggests a predominance of Pneumocystis carinii, Toxoplasma gondii and Cryptosporidium spp. For reasons which are unclear, parasitic infections such as Plasmodium falciparum, Strongyloides stercoralis and Entamoeba histolytica, where cell-mediated immune responses are also thought to be significant, do not appear to be opportunists of importance. It is being increasingly recognized that chemotherapy for parasitic diseases has a host-dependent component, although scientific data on this subject remain scanty. The management of opportunistic parasitic infections in patients infected with HIV is dogged by failures and relapses, aptly illustrating the notion of the relationship between chemotherapy and the immune response. This review discusses the immunity and chemotherapy of opportunistic parasite infections in patients infected with the Human Immunodeficiency Virus (HIV).

Beam hardening in X-ray reconstructive tomography (1976)

As a polychromatic X-ray beam passes through matter, low energy photons are preferentially absorbed, and the (logarithmic) attenuation is no longer a linear function of absorber thickness. This leads to various artifacts in reconstructive tomography. If a water bag is used, the nonlinear attenuation in bone causes a distortion of the bone values and a spill-over inside the skull, or 'pseudo-cortex' artifact. If no water bag is used, there is an additional effect due to the varying thickness of soft tissue which causes a depression of interior values, or 'cupping'. Both artifacts can be remedied by additional prefiltering of the beam and by applying a linearization correction to the detector outputs.
Evaluation of a Multiplex PCR Assay To Rapidly Detect Enterobacteriaceae with a Broad Range of β-Lactamases Directly from Perianal Swabs (2016)

We developed and evaluated multiplexed molecular beacon probes in a real-time PCR assay to identify prominent extended-spectrum-β-lactamase, plasmid-mediated AmpC β-lactamase (pAmpC) and carbapenemase genes directly from perianal swab specimens within 6 h. We evaluated this assay on 158 perianal swabs collected from hematopoietic stem cell transplant recipients and found that this assay was highly sensitive and specific for detection of CTX-M-, pAmpC-, and KPC-producing Enterobacteriaceae compared to culture on chromogenic agar.
Dietary Modulation of Inflammation‐Induced Colorectal Cancer through PPARγ (2009)

Mounting evidence suggests that the risk of developing colorectal cancer (CRC) is dramatically increased for patients with chronic inflammatory diseases. For instance, patients with Crohn's Disease (CD) or Ulcerative Colitis (UC) have a 12-20% increased risk for developing CRC. Preventive strategies utilizing nontoxic natural compounds that modulate immune responses could be successful in the suppression of inflammation-driven colorectal cancer in high-risk groups. The increase of peroxisome proliferator-activated receptor-γ (PPAR-γ) expression and its transcriptional activity has been identified as a target for anti-inflammatory efforts, and the suppression of inflammation-driven colon cancer. PPARγ down-modulates inflammation and elicits antiproliferative and proapoptotic actions in epithelial cells. All of which may decrease the risk for inflammation-induced CRC. This review will focus on the use of orally active, naturally occurring chemopreventive approaches against inflammation-induced CRC that target PPARγ and therefore down-modulate inflammation.
Cardiac complications in beta-thalassemia: From mice to men (2017)

Beta-thalassemia is an inherited hemoglobin disorder caused by reduced or absent synthesis of the beta globin chains of hemoglobin. This results in variable outcomes ranging from clinically asymptomatic to severe anemia, which then typically requires regular blood transfusion. These regular blood transfusions can result in an iron overload condition. The iron overload condition can lead to iron accumulation in various organs, especially in the heart, leading to iron overload cardiomyopathy, which is the major cause of mortality in patients with thalassemia. In the past decades, there is no doubt that the use of β-thalassemic mice as a study model to investigate the pathophysiology of iron overload cardiomyopathy and the role of various pharmacological interventions, has shed some light in understanding this serious complication and in improving the associated cardiac dysfunction. In this review, the effects that iron overload has on the hearts of β-thalassemic mice under conditions of iron overload as well as the efficacy of pharmacological interventions to combat these adverse effects on the heart are reviewed and discussed. The in-depth understanding of biomolecular alterations in the heart of these iron overload thalassemic mice will help give guidance for more effective therapeutic approaches in the near future. Impact statement Iron overload cardiomyopathy is a major cause of morbidity and mortality in patients with thalassemia. Since investigation of iron overload cardiomyopathy in thalassemia patients has many limitations, a search for an animal model for this condition has been ongoing for decades. In the past decades, there is no doubt that the use of β-thalassemic mice as a study model to investigate the pathophysiology of iron overload cardiomyopathy and the role of various pharmacological interventions, has shed some light in understanding this serious complication and in improving the associated cardiac dysfunction. In this review, the effects of iron overload on the hearts of β-thalassemic mice under conditions of iron overload as well as the efficacy of pharmacological interventions to combat these adverse effects on the heart are reviewed and discussed.
SBAS Vertical Protection Level Assessment in the Case of Error Reduction (2006)

Navigation system integrity is a quality and safety parameter, which alerts SBAS (satellite based augmentation system) users when the system exceeds tolerance limits. The environmental effects could cause position errors that exceed the computed protection level, i.e. system non-integrity events. In this work a novel error filtering algorithm for additional SBAS performance improvement is presented. It is simple to implement within the user receiver. The algorithm takes into consideration the kinematics of the individual user, which is equipped with inertial navigation system (INS) as well. Important relations between position error probability characteristics before and after filtering are delivered. These relations are used for new vertical protection level (VPL) determination. Using the proposed filtering algorithm and related to it VPL, system availability improvement without integrity sacrifice can be achieved

Grassmannian Differential Limited Feedback for Interference Alignment (2012)

Channel state information (CSI) in the interference channel can be used to reduce the dimension of received interference and helps achieve the channel's maximum multiplexing gain through what is known as interference alignment (IA). Most interference alignment algorithms require knowledge of all the interfering channels to compute the alignment precoders. CSI, considered available at the receivers, can be shared with the transmitters via limited feedback. When IA is done by coding over frequency extensions in a single antenna system, the required CSI lies on the Grassmannian manifold and its structure can be exploited in feedback. Unfortunately, the number of channels to be shared grows with the square of the number of users, creating too much overhead with conventional feedback methods. This paper proposes Grassmannian differential feedback to reduce feedback overhead by exploiting both the channel's temporal correlation and Grassmannian structure. The performance of the proposed algorithm is characterized both analytically and numerically as a function of channel length, mobility, and the number of feedback bits. The main conclusions are that the proposed feedback strategy allows IA to perform well over a wide range of Doppler spreads, and to approach perfect CSI performance in slowly varying channels. Numerical results highlight the trade-off between the frequency of feedback and the accuracy of individual feedback updates.
Advanced molding technique for optical transceivers (2002)

With the growing use of fiber optics in Local Area Networks (LANs), efforts to cost reduce the optical components has intensified. In general, optoelectronic components for Fiber Distributed Data Interface (FDDI) and Fiber Channel LANs have been LED-based Optical Data Links (ODLs). Due to the bi-directional nature of most links, the trend has been towards the integration of simplex optical transmitters and receivers into Optical Transceivers. Further cost reductions through the use of automated assembly processes such as two step overmolding have also been reported recently. In this paper, we propose a molding technique designed to further cost reduce optoelectronic devices. The technique involves the use of a one-step overmolding process to encapsulate the electronics and injection molded connector receptacle. The injection molded receptacle is designed to provide support and alignment for the Optical Sub-Assemblies (OSAs) prior to overmolding. With the electronics on its substrate (Leadframe/HIC), the optics on the receptacle, and the link between the optics and the electronics complete (wirebonded), the substrate and the receptacle are overmolded in one step. This technique eliminates the need for the first mold process inherent in the two stage overmolding technique. The one step method also removes the need for precision mold features required for optical port alignment and subsequent final assembly (necessary in the two step method). This method, however, combines five active components into one integrated unit-requiring the use of "Known Good Die" to ensure a trouble free device.
Some perturbation solutions in laminar boundary-layer theory (1963)

The velocity fields associated with a variety of flows which may be described by perturbations of the Blasius solution are considered. These are flows which, for example, because of localized mass transfer, involve the initial-value problem of boundary-layer theory, or which involve a variable ratio of the viscosity-density product, or finally which involve mass transfer. The perturbation solutions are presented so that in accord with the usual linearization procedures further applications for the determination of first-order effects can be readily made. In addition, each of these perturbations involves a common differential operator whose eigenfunctions form a complete orthogonal set. Accordingly, a procedure for systematically improving each perturbation solution to obtain higher-order effects by quadrature is presented. The results of applications in several cases are given and are compared to more accurate solutions where available.

Three-Dimensional Parallel Finite Element Simulation of Natural Gas Flow in a Porous Media. (1998)

A parallel-three-dimensional finite element simulation of natural gas flow in a porous media was developed for use in multiple well reservoirs. Developed with this simulation was a set of graphical applications to provide a geometric description of the reservoir, viewing of the generated mesh and viewing of results generated by the simulation. An adaptive mesh scheme for the dynamic refinement and derefinement of the mesh during the solution process is presented. The adaptive mesh scheme utilizes a mesh storage technique designed to reduce the space requirements of the mesh. This adaptive mesh technique was applied to an unstructured mesh. A parallel algorithm for the frontal solution technique was developed and implemented in C++ on small clusters of Microsoft Windows NT 4.0, Linux, and PowerPC workstations using MPI. The increased accuracy of these simulations was verified for the Eugene Island natural gas reservoir, located off the coast of Louisiana. The results for the Eugene Island example are more accurate than results from previous finite difference solutions for the same simulation.
Evaluation of semiconducting tin oxide as an electrocatalyst support (1979)

Semiconducting tin oxide prepared from chloride salts has been evaluated as an electrocatalyst support. The support had an electrical conductivity comparable to that of conventional active carbon supports. Platinum catalysts prepared on tin oxide were found to have low activity for methanol electro-oxidation. Characterisation by X-ray diffraction, temperature-programmed reduction and cyclic voltammetry revealed that the platinum for the greater part was not present as platinum metal. It is proposed that the calcination of the platinum catalyst in air resulted in a strong interaction or compound formation between the platinum species and the tin oxide, rendering the platinum difficult to reduce.
