Fermentation mechanism of fucose and rhamnose in Salmonella typhimurium and Klebsiella pneumoniae (1985)

An equimolar amount of 1,2-propanediol was detected in the medium when Salmonella typhimurium or Klebsiella pneumoniae fermented L-fucose or L-rhamnose. These metabolic conditions induced a propanediol oxidoreductase that converted the lactaldehyde formed in the dissimilation of either sugar into the diol. The enzyme was further identified by cross-reaction with antibodies against Escherichia coli propanediol oxidoreductase. This indicates that L-fucose and L-rhamnose fermentation takes place in these species by 1,2-propanediol production and excretion.
An Optically Differential Reconfigurable Gate Array VLSI Chip with a Dynamic Reconfiguration Circuit (2005)

An optically differential reconfigurable gate array (ODRGA) is a type of field programmable gate array (FPGA), but its gate array can be reconfigured optically in less than 6 ns. We have fabricated a 68 gate-count ODRGA. However, optical differential reconfiguration circuits, which are capable of optical detection of configuration contexts and which can support reconfiguration of an arbitrary part of its gate array bit-by-bit, occupy up to 47% of the implementation area of ODRGA-VLSI chip and prevent realization of a high gate-count ODRGA. Therefore, a dynamic optical differential reconfiguration circuit was developed to reduce the implementation area of optical reconfiguration circuits. It has been evaluated separately. This paper presents the first 476 gate count ODRGA-VLSI chip with a standard 0.35 /spl mu/m 3-metal CMOS process technology using an improved dynamic optical differential reconfiguration circuit. In addition, the dynamic reconfiguration frequency and performance of logic blocks are shown using HSPICE simulation results. Finally, this paper presents an estimation of the use of a standard 0.35 /spl mu/m 3-metal 14.2/spl times/74.2 mm chip.
An analysis of the structure and complexity of nonlinear binary sequence generators (1976)

A method of analysis is presented for the class of binary sequence generators employing linear feedback shift registers with nonlinear feed-forward operations. This class is of special interest because the generators are capable of producing very long "unpredictable" sequences. The period of the sequence is determined by the linear feedback connections, and the portion of the total period needed to predict the remainder is determined by the nonlinear feed-forward operations. The linear feedback shift registers are represented in terms of the roots of their characteristic equations in a finite field, and it is shown that nonlinear operations inject additional roots into the representation. The number of roots required to represent a generator is a measure of its complexity, and is equal to the length (number of stages) of the shortest linear feedback shift register that produces the same sequence. The analysis procedure can be applied to any arbitrary combination of binary shift register generators, and is also applicable to the synthesis of complex generators having desired properties. Although the discussion in this paper is limited to binary sequences, the analysis is easily extended to similar devices that generate sequences with members in any finite field.
Region of interest cone beam tomography with prior CT data (2004)

Recent so-called very short-scan fan-beam reconstruction algorithms make it possible to reconstruct objects within the convex hull of the source path provided that the object is completely contained within the filed of view in all projections. In this work, we extend this result to the truncated cone-beam projection scenario that is typical of mobile C-arms in surgery under the assumption that a prior computed tomography scan is available and that the anatomy has only changed due to surgery within the convex hull of the source path. Practical algorithms and simulation results are given.
Velocity analysis for transversely isotropic media (1995)

Abstract The main difficulty in extending seismic processing to anisotropic media is the recovery of anisotropic velocity fields from surface reflection data. We suggest carrying out velocity analysis for transversely isotropic (TI) media by inverting the dependence of P-wave moveout velocities on the ray parameter. The inversion technique is based on the exact analytic equation for the normal-moveout (NMO) velocity for dipping reflectors in anisotropic media.We show that P-wave NMO velocity for dipping reflectors in homogeneous TI media with a vertical symmetry axis depends just on the zero-dip value V nmo (0) and a new effective parameter eta that reduces to the difference between Thomsen parameters epsilon and delta in the limit of weak anisotropy. Our inversion procedure makes it possible to obtain eta and reconstruct the NMO velocity as a function of ray parameter using moveout velocities for two different dips. Moreover, V nmo (0) and eta determine not only the NMO velocity, but also long-spread (nonhyperbolic) P-wave moveout for horizontal reflectors and the time-migration impulse response. This means that inversion of dip-moveout information allows one to perform all time-processing steps in TI media using only surface P-wave data. For elliptical anisotropy (epsilon = delta ), isotropic time-processing methods remain entirely valid. We show the performance of our velocity-analysis method not only on synthetic, but also on field data from offshore Africa.Accurate time-to-depth conversion, however, requires that the vertical velocity V P0 be resolved independently. Unfortunately, it cannot be done using P-wave surface moveout data alone, no matter how many dips are available. In some cases V P0 is known (e.g., from check shots or well logs); then the anisotropy parameters epsilon and delta can be found by inverting two P-wave NMO velocities corresponding to a horizontal and a dipping reflector. If no well information is available, all three parameters (V P0 , epsilon , and delta ) can be obtained by combining our inversion results with shear-wave information, such as the P-SV or SV-SV wave NMO velocities for a horizontal reflector.Generalization of the single-layer NMO equation to layered anisotropic media with a dipping reflector provides a basis for extending anisotropic velocity analysis to vertically inhomogeneous media. We demonstrate how the influence of a stratified anisotropic overburden on moveout velocity can be stripped through a Dix-type differentiation procedure.
Extended depth of field using the logarithmic asphere (2003)

Transmission functions are derived for a novel logarithmic aspheric lens that provides an extended depth-of-field when used in an integrated digital processing system. Diffraction-theory equations valid in the non-paraxial case are presented together with a comparative study of two designs. This lens can be used either singly or in conjunction with a standard photographic lens. A tenfold increase in the depth-of-field has been obtained.
Three-dimensional cell migration does not follow a random walk (2014)

Cell migration through 3D extracellular matrices is critical to the normal development of tissues and organs and in disease processes, yet adequate analytical tools to characterize 3D migration are lacking. Here, we quantified the migration patterns of individual fibrosarcoma cells on 2D substrates and in 3D collagen matrices and found that 3D migration does not follow a random walk. Both 2D and 3D migration features a non-Gaussian, exponential mean cell velocity distribution, which we show is primarily a result of cell-to-cell variations. Unlike in the 2D case, 3D cell migration is anisotropic: velocity profiles display different speed and self-correlation processes in different directions, rendering the classical persistent random walk (PRW) model of cell migration inadequate. By incorporating cell heterogeneity and local anisotropy to the PRW model, we predict 3D cell motility over a wide range of matrix densities, which identifies density-independent emerging migratory properties. This analysis also reveals the unexpected robust relation between cell speed and persistence of migration over a wide range of matrix densities.
THE WAVE OF ADVANCE OF ADVANTAGEOUS GENES (1937)

The articles published by the Annals of Eugenics (1925–1954) have been made available online as an historical archive intended for scholarly use. The work of eugenicists was often pervaded by prejudice against racial, ethnic and disabled groups. The online publication of this material for scholarly research purposes is not an endorsement of those views nor a promotion of eugenics in any way.
Nitric Oxide Transport in Blood: A Third Gas in the Respiratory Cycle (2011)

The trapping, processing, and delivery of nitric oxide (NO) bioactivity by red blood cells (RBCs) have emerged as a conserved mechanism through which regional blood flow is linked to biochemical cues of perfusion sufficiency. We present here an expanded paradigm for the human respiratory cycle based on the coordinated transport of three gases: NO, O₂, and CO₂. By linking O₂ and NO flux, RBCs couple vessel caliber (and thus blood flow) to O₂ availability in the lung and to O₂ need in the periphery. The elements required for regulated O₂-based signal transduction via controlled NO processing within RBCs are presented herein, including S-nitrosothiol (SNO) synthesis by hemoglobin and O₂-regulated delivery of NO bioactivity (capture, activation, and delivery of NO groups at sites remote from NO synthesis by NO synthase). The role of NO transport in the respiratory cycle at molecular, microcirculatory, and system levels is reviewed. We elucidate the mechanism through which regulated NO transport in blood supports O₂ homeostasis, not only through adaptive regulation of regional systemic blood flow but also by optimizing ventilation-perfusion matching in the lung. Furthermore, we discuss the role of NO transport in the central control of breathing and in baroreceptor control of blood pressure, which subserve O₂ supply to tissue. Additionally, malfunctions of this transport and signaling system that are implicated in a wide array of human pathophysiologies are described. Understanding the (dys)function of NO processing in blood is a prerequisite for the development of novel therapies that target the vasoactive capacities of RBCs.
Tumour treating fields in a combinational therapeutic approach (2018)

The standard of care for patients with newly diagnosed Glioblastoma multiforme (GBM) has remained unchanged since 2005, with patients undergoing maximal surgical resection, followed by radiotherapy plus concomitant and maintenance Temozolomide. More recently, Tumour treating fields (TTFields) therapy has become FDA approved for adult recurrent and adult newly-diagnosed GBM following the EF-11 and EF-14 trials, respectively. TTFields is a non-invasive anticancer treatment which utilizes medium frequency alternating electric fields to target actively dividing cancerous cells. TTFields selectively targets cells within mitosis through interacting with key mitotic proteins to cause mitotic arrest and cell death. TTFields therapy presents itself as a candidate for the combinational therapy route due to the lack of overlapping toxicities associated with electric fields. Here we review current literature pertaining to TTFields in combination with alkylating agents, radiation, anti-angiogenics, mitotic inhibitors, immunotherapies, and also with novel agents. This review highlights the observed synergistic and additive effects of combining TTFields with various other therapies, as well highlighting the strategies relating to combinations with electric fields.

An evaluation of direct methane conversion processes (1990)

Methane is the primary constituent of both natural gas and the associated gas resulting from crude oil production. These gases have little value unless they can be moved to large-scale consumers through a pipeline or transported as liquefied gases. Because conversion of methane to a transportable liquid hydrocarbon fuel would open new markets, it is a goal being actively pursued by many groups around the world. Currently, two large-scale, viable approaches for converting methane to liquid hydrocarbons are being used: the methanol-to-gasoline (MTG) route, and the Fischer--Tropsch (FT) route. Both of these processes begin with the production of synthesis gas from methane,which is a high-temperature, endothermic, costly operation. Concepts for directly converting methane to a liquid hydrocarbon fuel without reforming methane to synthesis gas conceptually appear attractive. A few have reached the stage where a preliminary evaluation directed at understanding the critical process factor is possible. The authors report on their studies involving the following process schemes: oxidative coupling, partial oxidation, and oxyhydrochlorination.
HIV‐1 variability and progression to AIDS: A longitudinal study (1990)

HIV-1 replicative activity and its relation to the clinical and immunological evolution of infection was studied in a group of 150 HIV-1 seropositive Italian i.v. drug abusers over a 1 year period. HIV-1 was isolated from 90 (60%) subjects; two groups of isolates were distinguished, according to replicative activity "in vitro" and ability to induce cytopathic effects in cell cultures, and were termed "rapid-high" and "slow-low" viruses, in agreement with other workers. Rapid-high viruses were recovered more frequently from patients with ARC/AIDS, while slow-low viruses seemed related to the asymptomatic period of infection. The replicative properties of HIV-1 seem to affect strongly the course of disease. In fact, an important CD4 cell decline occurred in asymptomatic subjects with rapid-high virus infection; asymptomatic subjects with negative viral cultures or with slow-low viruses showed no such decline. Asymptomatic subjects with negative viral cultures had no signs of disease during the observation period, while 9% with slow-low virus and 45% with rapid-high virus progressed to AIDS.
A Google-Map-Based Arterial Traffic Information System (2007)

Web-based mapping technologies have been utilized for traffic information systems. However, most such systems are for freeways and very few of them focus on arterials or urban streets. This paper presents a real-time Google-map-based Arterial Traffic Information (GATI) system for urban streets in the City of Bellevue, Washington State. Open source web tools and emerging web technologies, such as Ajax, are used in implementing the system to ensure its performance and minimize its cost. Convenient administrative functions are enabled through advanced database design and the Model-View-Controller (MVC) application. This GATI system, though presented and demonstrated by using Bellevue's data, is a general technology that can be applied to any arterial network.

Molecular Characterization of β‐Lactamase Inclusion Bodies Produced in <i>Escherichia coli.</i> 1. Composition (1993)

We have determined the macromolecular composition of inclusion bodies formed by overexpressing beta-lactamase from three different expression systems as a function of the growth conditions. The inclusion bodies were purified by differential gradient centrifugation and detergent extraction. Both the expression system and the growth conditions were shown to have a pronounced effect on inclusion body composition. Specifically, contaminating polypeptides ranged from less than 5% to over 50% of the total protein content. Phospholipids composed 0.5-13% of the inclusion bodies. Nucleic acids represented a minor impurity for both cytoplasmic and periplasmic inclusion bodies. Cytoplasmic inclusion bodies of the mature beta-lactamase had the lowest amount of impurities, irrespective of the growth conditions. On the other hand, large amounts of outer membrane proteins and phospholipids were observed in periplasmic inclusion bodies from cells grown at basic pH. Our results show that, at least under some growth conditions, protein aggregation in vivo is highly specific, and the presence of contaminating proteins in inclusion bodies is due to incomplete purification following cell lysis.
Automated Verification of Load Test Results in a Continuous Delivery Deployment Pipeline (2015)

Continuous delivery is a software development methodology that aims to reduce development cycle time by putting a strong emphasis on automation, quality and rapid feedback. This thesis develops an automated method for detecting performance regressions as part of a continuous delivery deployment pipeline. The chosen method is based on control charts, a tool commonly used within statistical process control. This method is implemented as part of a continuous delivery deployment pipeline and its ability to detect performance regressions is then evaluated by injecting various performance bottlenecks in a sample application. The results from this thesis show that using a control chart based approach is a viable option when trying to automate verification of load test results in the context of continuous delivery.

MONITORING LEAKING GASES BY OP-FTIR REMOTE SENSING (2002)

Measurement of leaking gases using Open Path Fourier Transform Infrared (OP-FTIR) spectroscopy was carried out in this study to acquire Path Integrated Concentration (PIC) data. Three hazardous Volatile Organic Compounds (VOCs) namely methylene chloride, chloroform and acetone were analyzed. For the two-component leaking source, the PIC data were easily obtained through ordinary calculation and compared to those obtained from Artificial Neural Network (ANN). When the leaking source was composed of three VOCs whose characteristic peaks interfere with each other, it was necessary to do spectral correction for multicomponent analysis with ANN. The Absorbance-Wavenumber-Time 3D spectra of the leaking sources and concentration variations with the leaking time were plotted. The results showed that OP-FTIR is a good quantitative analytical method for indoor or field air pollution. Further more, the remote sensing OP-FTIR system could be utilized to continuously monitor many more toxic gases and work as an alert system for the real time monitoring of hazardous gases beyond normal working conditions of various kinds of areas, such as living or industrial areas.
The Proportion of Lymphocytic Inflammation with CD123-positive Cells in Lupus Erythematous Profundus Predict a Clinical Response to Treatment (2014)

Lupus erythematosus profundus is a rare inflammatory disorder of subcutaneous fat in patients with lupus ery-thematosus. Previous reports suggested that plasmacytoid dendritic cells, which expressed CD123 and CD303 antigens, play a central proinflammatory role in the patho-genesis of lupus erythematosus. To find the factors that determine the response to treatment, we analysed 23 skin specimens from the patients with lupus erythematosus profundus. The patients with considerable lymphocytic inflammation with high percentages of CD123+ cells in dermis and subcutaneous fat significantly responded to the systemic corticosteroid therapies. On the other hand, the patients with minor lymphocytic inflammation with low percentages of CD123+ cells showed poor response to treatments. The mean percentage of CD123+ cells in patients who showed good response to therapy was significantly higher than those that showed poor response (p = 0.027). These results suggest that the clinical response to treatment of lupus erythematosus profundus could be predicted from the histological features.
