Hydrolytic Stability versus Ring Size in Lactams:  Implications for the Development of Lactam Antibiotics and Other Serine Protease Inhibitors (2000)

beta-Lactam antibiotics act by acylating a serine hydroxyl group in the catalytic center of bacterial proteases. This requires, among other things, suitable reactivity of the lactam moiety. To evaluate the possible suitability of other lactam systems, kinetic studies were performed using the model reaction of lactams with hydroxide. Following the pace of the reaction by NMR, we found gamma-butyrolactam to be hydrolyzed considerably slower than beta-propiolactam. Surprisingly, delta-valerolactam and beta-propiolactam had the same reactivity. beta-Lactam antibiotics were more reactive than both by approximately a factor of 10(3). Medium-sized lactams were least susceptible to hydrolysis. The study highlights the as yet overlooked six-membered lactam ring as a promising vantage point for the development of new classes of antiinfectives and other serine protease inhibitors.

Downhole savings as a result of minimized drilling requirements, reduced casing requirements, and other equipment and operations are discussed. Additional cost savings resulting from decreased surface and support requirements will are also covered in detail. Additionally, intangible cost savings in the form of reduced rig mobilization costs, lessened HSE costs and lessened rig time cost savings are included in the discussion.
Reading Sŏktok Kugyŏl materials based on Ŏnhae materials (2014)

In this paper, we discussed some advantages of and points of attempt to research how to read Hancha (漢字) with Kugyŏl (口訣) markings based on the premise, that the tradition of Hanmun Hundok (漢文訓讀) in Sŏktok Kugyŏl (釋讀口訣) materials has been succeeded to Ŏnhae (諺解) materials since the mid-15th century, the promulgation of Hunmin Chyŏngŭm (訓民正音), and based on Ŏnhae (諺解) system in these Ŏnhae (諺解) materials. As a result, Hundok (訓讀) systems of Sŏktok Kugyŏl (釋讀口訣) materials had much resemblance to the Non-Buddhist (Confucian) Ŏnhae (諺解) materials since the end of 15th century. Therefore, Non-Buddhist (Confucian) Ŏnhae (諺解) materials occupy an important position to consider the reading methods of Sŏktok Kugyŏl (釋讀口訣) materials.
On Outage Capacity of Secondary Users in Fading Cognitive Radio Networks with Primary User's Outage Constraint (2009)

This paper considers a cognitive radio network where a secondary user shares the same narrow band with a primary user for transmission. Instead of adopting the conventional interference-power/interference-temperature constraint, this paper proposes a new type of constraint for the secondary user to protect the primary transmission, which limits the maximum outage probability of the primary transmission subject to the secondary user's interference to be below a prescribed target. Under this newly proposed constraint along with the average/peak transmit power constraint, the paper derives the optimal power allocation strategies over block-fading channels for the secondary user to achieve its outage capacity. It is shown by simulations that the derived power allocation strategies achieve substantial outage capacity gains for the secondary user over the conventional power control policies based upon the interference-temperature constraint, given the same primary user's outage probability constraint.
[Effect of bortezomib on the drug sensitivity of imatinib resistant K562/G01 cells]. (2011)

BOR can enhance the imatinib sensitivity of imatinib resistant K562/G01 cell. The mechanism may be related to cell cycle phase arrested at G2/M and down-regulation of COX-2 and mdr1 expression.
Performance evaluation of TCP/IP protocol implementations in end systems (1999)

Conventional protocol implementation suffers in data-moving operations, limiting the maximum throughput. Experiments have measured the large incidence of these operations in a conventional protocol such as TCP/IP running in a Unix environment. To overcome this drawback protocol implementations have been proposed involving a processor and network interface that could share the same storage buffer. An analytical model is presented for evaluating the performance of different TCP/IP protocol implementations in end systems. The model uses a closed queueing network, employing a processor sharing service centre for the processing unit and two FCFS service centres for the core memory and network interface. Performance results (throughput, utilisation factor, mean queue length, etc.) allow comparison with conventional, two-copy and single-copy implementations of TCP/IP. Moreover, the model allows estimation of the influence on performance of other design parameters, i.e. memory bandwidth, number of packets in the network, socket buffer dimension and interface data rate.

Recent advances in phototherapy for psoriasis (2016)

Phototherapy involves repeated exposure of the skin to ultraviolet light to treat various inflammatory skin conditions such as psoriasis. Recent studies have identified specific immunologic effects of phototherapy that may underlie phototherapy efficacy. Furthermore, recent advancements have been made in developing safe and effective targeted phototherapy modalities for difficult-to-treat areas such as scalp psoriasis. Targeted phototherapy in the form of the excimer laser holds potential for more aggressive, effective treatment and long-lasting remission of psoriasis. Phototherapy is now also used successfully with biologic agents as combination therapy to treat recalcitrant psoriasis. Therefore, though one of the oldest therapeutic modalities for psoriasis, phototherapy remains a mainstay treatment with promise for further advancement.
Classification of Ripple Marks (1977)

Although ripple marks are extensively used in paleogeographic and environmental reconstructions, there is no generally accepted classification of them. The few formal classifications that have been proposed and the many informal classifications that have been used commonly recognize two major classes of ripples: current and either wave or oscillation types. Despite the seeming simplicity of this system, confusion has arisen because usage varies considerably. In some cases the same ripple type has been called current, wave-formed, or oscillation ripples by different authors. To resolve this problem we propose a classification that recognizes four major ripple types: wave formed, current formed, interference, and eolian. Three of the groups are aqueous, the fourth eolian. Within each group several varieties are distinguished. The most common varieties are: (wave-formed) oscillation, linear, and wave-dominated combined:-flow; (current-formed) cuspate, linguoid, dune, antidune, and current-dominated combined-flow; (interference) tadpole nest, ladderback, cuspate and secondary, and rhomboid; and (eolian) sand ripples. Common names are retained, even where past usage is ambiguous, because they are descriptive and already in general use. Each ripple variety is readily identified by descriptive criteria that are related to mode of formation. Thus the classification is both genetic and descriptive. Accordingly, the ripple types can be identified objectively and also are useful for environmental reconstructions.

Effects of Tension upon the Surface Accuracy of a Rectangular Membrane Element of a Space Reflector (2005)

The surrface accuracy of a rectangular membrane element subjected to anisotropic tension in a faceted reflector surface is investigated. The rectangular membrane element is assumed to be placed at an arbitrary place on the reflector surface with an arbitrary rotation angle between the side of the membrane and the direction of the principal curvature of the reflector surface. Rectangular membranes with two kinds of boundaries are considered. One is a coincident-edge membrane whose boundary coincides with the approximate parabolic surface at the local point where the membrane is placed. The other membrane is a coincident-optimum-edge membrane, which is obtained by minimizing the rms error using normal translation of the coincident-edge membrane. The deflection and the surface error of the membrane are calculated based on an analytical solution of the linear membrane equation. In a certain range of parameters, it is found that the appropriate tension ratio reduces the surface error of a membrane element as compared with isotropic tension. The surface error of a slender membrane becomes lower if the longer side of the membrane is loaded with higher tension. The more slender the membrane, the smaller the surface error. The minimum surface error is obtained when the longer side is placed parallel to the direction of the larger principal curvature at the location and the longer side is loaded with higher tension. The ratio of the surface error of a coincident-optimum-edge to that of a coincident-edge membrane is approximately 0.4 - 0.5 and depends only on the ratio of the aspect ratio of the membrane and the tension ratio parameter.
Variations on Ethernet traffic monitoring (2002)

The network traffic depends upon the types of requests from network users. Consequently, network traffic monitoring is sensitive to system workload caused by the users. In this project, we study the Ethernet traffic analysis and performance factors which affect the data receiving performance. In brief, we have accomplished the following: study of related Ethernet monitoring efforts; writing the sending and receiving programs above the NIT protocol; working through the Sniffer's network analyzer; and tests of the performance effects of variations on NIT buffer size, CPU power, and available memory space. The report of this project gives insight into the performance issues with, various system parameters, particularly in the file server's alternatives.< <ETX xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">></ETX>

Modern computing technology applied to underwater acoustic positioning systems (2002)

Two of the enabling technologies of the 90s, graphical user interfaces (GUIs) and digital signal processing (DSP), are being applied to underwater acoustic positioning systems. The industry-standard IBM PC computing hardware architecture running the Microsoft Windows operating system and GUI provides designers of acoustic positioning systems with a low-cost, yet powerful, system architecture for the processing of user input and the presentation of positioning data. The popularity of MS Windows almost guarantees that a user interface designed around it will have a familiar "look and feel" to potential users, providing for a system which is easier to learn and use than found in the past. Digital signal processing provides a powerful, flexible, and low-cost means by which to perform acoustic signal detection. The Nautronix RS910 series Ultra-short Baseline/Long Baseline Acoustic Positioning System uses embedded DSPs to perform acoustic signal processing and an industrial PC running MS Windows to perform user interface and data storage functions. Designed as the successor to the Honeywell RS900 series systems, the RS910 replaces the analog signal processing system with a much more flexible DSP-based system.
Oxford (2012)

Abstract This chapter focuses on John Davenport when he left Coventry to study at Oxford University in 1613. Davenport chose Magdalen Hall as the place to resume his studies because of its puritan orientation. A number of his contemporaries left records that enable us to re-create what his typical day might have been like. Davenport would have arisen at five or six in the morning to prepare for the day and to pray his private prayers. The tensions of academic life were alleviated by opportunities for recreation. Plays, often written by college members, were performed in the halls, and musical performances were common. Many colleges had areas set aside for bowling and tennis.
A Hierarchy of Turbulence Closure Models for Planetary Boundary Layers (1974)

Turbulence models centered on hypotheses by Rotta and Kolmogoroff are complex. In the present paper we consider systematic simplifications based on the observation that parameters governing the degree of anisotropy are small. Hopefully, we shall discern a level of complexity which is intuitively attractive and which optimizes computational speed and convenience without unduly sacrificing accuracy. Discussion is focused on density stratified flow due to temperature. However, other dependent variables—such as water vapor and droplet density—can be treated in analogous fashion. It is, in fact, the anticipation of additional physical complexity in modeling turbulent flow fields that partially motivates the interest in an organized process of analytical simplification. For the problem of a planetary boundary layer subject to a diurnally varying surface heat flux or surface temperature, three models of varying complexity have been integrated for 10 days. All of the models incorporate identical empirical constants obtained from neutral flow data alone. The most complex of the three models requires simultaneous solution of 10 partial differential equations for turbulence moments in addition to the equations for the mean velocity components and temperature; the least complex eliminates all of the 10 differential equation whereas a “compromise” model retains two differential equations for total turbulent energy and temperature variance. We conclude that all of the models give nearly the same results. We find the two-differential-equation model particularly attractive.
Three Optical Procedures for Local Large‐Strain Measurement (2001)

Abstract: Optical methods have been developed to measure large strains. Two alternatives are presented: the first one uses a cross grating, obtained by an innovative manufacturing process and the second one uses a mark‐tracking technique. The production of the grating is based on the deposit of a thin film through a master grid under vacuum. This creates small studs independent of each other, on the specimen surface. For the grid interrogation two techniques are discussed, one using the analysis of the optical diffraction figure and the other one the Fast Fourier Transform algorithm. Markers are simply deposited on the studied surface with a pen and strain determination is then obtained by mark‐tracking. The experimental validation consists of several simple tensile tests. Experimental results for polymers and latex materials confirm the quality of measurement. Strains are measured for values up to 1,200% without loss of information, with a strain accuracy close to 5times10 ‐4 at minimum gauge lengths of 0.125 mm.
Fast Chase Decoding Algorithms and Architectures for Reed–Solomon Codes (2011)

Chase decoding is a prevalent soft-decision decoding method for algebraic codes where an efficient bounded-distance decoder is available. Essentially, it repeatedly applies bounded-distance decoding upon combinatorially flipping certain least reliable bits (or patterns for nonbinary case). In this paper, we devise a one-pass Chase decoding algorithm of Reed-Solomon codes such that the desired error locator polynomial by flipping an error pattern is obtained in one pass (when operated in parallel) through utilizing the preceding results. This is effectively achieved through cumulative interpolation and linear-feedback-shift-register (LFSR) synthesis techniques. Furthermore, through converting the algorithm into the transform domain, exhaustive root search for each error locator polynomial is circumvented. Computationally, the new algorithm exhibits linear complexity , in attempting to determine a candidate codeword associated with each additionally flipped symbol/pattern; it compares favorably to quadratic complexity by straightforwardly utilizing hard-decision decoding, where and denote the code length and minimum distance, respectively. We also reveal a corrected algorithm for one-pass generalized minimum distance (GMD) decoding for Reed-Solomon codes from Koetter's original work. In addition, we devise a highly efficient one-pass Chase decoding algorithm for binary Bose-Chaudhuri-Hocquenghem (BCH) codes by taking advantage of a key characteristic of the Berlekamp algorithm. Finally, we present a systolic very large-scale integration (VLSI) decoder architecture through slightly compromising the proposed one-pass Chase decoding algorithm. It takes clock cycles to complete one iteration by flipping one error pattern. Both circuit and memory complexities are dictated by the dimension of flipping patterns; in particular, they are independent of the code length or the minimum distance , rendering it highly attractive for various applications.
X-Band CMOS Power Amplifier Using Mode-Locking Method For Sensor Applications (2012)

Abstract An X-band CMOS power amplifier using a mode-locking method for sensor applications is designed with a TSMC 0.13-μm RF CMOS process. The cascode structure is adapted to remove the reliability problems between the drain and gate voltages of the NMOS. Additionally, the mode-locking method is used to improve the efficiency and gain of the amplifier. We proposed the method to adapt the mode-locking topology to the cascode structure. The measured power added efficiency is 27%, while the saturated output power is 14 dBm at an operation frequency of 8.9 GHz. The designed chip size is 700 by 550 μm2.

Diabetes mellitus is equally frequent in chronic HCV and HBV infection. (2002)

Diabetes is equally frequent in both HBV and HCV related disease but is significantly more in those with chronic liver disease than in controls. The pancreatic damage secondary to extrahepatic viral replication appears to be the major cause but genetic factors also need to be explored.
