Synthesis of Libraries of 16β‐Aminopropyl Estradiol Derivatives for Targeting Two Key Steroidogenic Enzymes
Authors: Ciobanu Liviu C. , Poirier Donald 
Published: September 2006

AbstractTwo libraries, each consisting of 48 16β‐aminopropyl estradiol derivatives, phenols and sulfamates, respectively, were synthesized by solid‐phase parallel chemistry through a seven‐step reaction sequence. Following the attachment of a C18‐steroid sulfamate precursor on a trityl chloride resin, diversity elements were first introduced on the 16β‐aminopropyl chain of the steroid by acylation reactions with eight Fmoc‐amino acids. After deprotection, the free amine function of the resulting compounds was reacted with six carboxylic acids for the introduction of a second diversity level. The two variants employed for the cleavage of compounds from the solid support, acidic and nucleophilic, allowed the corresponding libraries of sulfamate and phenol derivatives in yields of 8–50 % and 13–58 % to be obtained with an average HPLC purity of 94 % and 91 %, respectively. Potent steroid sulfatase inhibitors and interesting SAR results were generated from the screening of the sulfamate library. Furthermore, moderate inhibitors of type 1 17β‐HSD resulted from the partial screening of phenol library. Thus, these two categories of compounds were synthesized to rapidly identify potential inhibitors of steroid biosynthesis for the hormonal therapy of estrogen‐dependent diseases, and also to demonstrate the versatility and efficiency of the recently developed sulfamate linker.
Voltammetric Sizing of a Sphere
Authors: Fietkau Nicole , Chevallier François G. , Jiang Li , Jones Timothy G. J. , Compton Richard G. 
Published: September 2006

AbstractThe size of a glass sphere positioned in the center of a microdisk electrode is determined by using a simple electrochemical procedure and is confirmed, additionally, by a microscopical measurement of the sphere at the time of the electrochemical measurement. The cyclic voltammetric response of the naked electrode and of the electrode with the sphere positioned in its center is recorded over a wide range of scan rates (0.002–1.5 V s−1). The size of the sphere is then determined by comparison of the experimental voltammogram with simulations for each individual scan rate.
Clock synchronization for packet networks using a weighted least‐squares error filtering technique and enabling circuit emulation service
Authors: Aweya James , Montuno Delfin Y. , Ouellette Michel , Felske Kent 
Published: September 2006

AbstractCircuit emulation service (CES) allows time‐division multiplexing (TDM) services (T1/E1 and T3/E3 circuits) to be transparently extended across a packet network. With circuit emulation over IP, for instance, TDM data received from an external device at the edge of an IP network is converted to IP packets, sent through the IP network, passed out of the IP network to its destination, and reassembled into TDM bit stream. Clock synchronization is very important for CES. This paper presents a clock synchronization scheme based on a double exponential filtering technique and a linear process model. The linear process model is used to describe the behaviour of clock synchronization errors between a transmitter and a receiver. In the clock synchronization scheme, the transmitter periodically sends explicit time indications or timestamps to a receiver to enable the receiver to synchronize its local clock to the transmitter's clock. A phase‐locked loop (PLL) at the receiver processes the transmitted timestamps to generate timing signal for the receiver. The PLL has a simple implementation and provides both fast responsiveness (i.e. fast acquisition of transmitter frequency at a receiver) and significant jitter reduction in the locked state.

Multichannel speech separation and localization by frequency assignment
Authors: Ihara Takehiro , Handa Masaki , Nagai Takayuki , Kurematsu Akira 
Published: September 2006

AbstractIn this paper, we propose frequency assignment as a method for multichannel speech separation. In this method, the magnitudes of the absolute values of each component in the frequency domain are compared, then based on this comparison result determines to which channel a frequency component originally belongs. The speech is separated by assigning the frequency to the determined channel. Therefore, it becomes possible to separate multichannel speech with a low computational load. However, it has the restriction that each speaker must speak close to his microphone. For situations in which this premise does not hold, we present a solution that uses beam‐forming toward the sound sources. We also show the application of the frequency assignment to sound source localization. In this paper, we demonstrate the usefulness of the proposed method through simulation tests and tests in a realistic environment. © 2006 Wiley Periodicals, Inc.

A design of array‐microphone system using directional microphones and two‐dimensional FIR filters
Authors: Naono Hiroyuki , Nishikawa Kiyoshi 
Published: September 2006

AbstractDelay‐and‐sum array microphones consisting of a linear array of microphones can achieve a sharp directivity at high frequencies. A disadvantage is that the directivity depends on the frequency. In order to resolve this problem, an array microphone using a fan filter has been proposed. However, in order to form a sharp beam at a low frequency, it is necessary to increase the filter order and the array length. In this paper, we report improvement of the directivity of an array microphone realizing a narrow beam with a relatively low order of the filter by means of a two‐dimensional frequency domain design. Employing two microphones, a first‐order pressure‐gradient microphone is formed. The spacing of the microphones is set for high sensitivity and broad bandwidth in the operating frequency range. The amplitude characteristics are obtained in the two‐dimensional frequency domain. These microphone units are placed along a line and are cascaded to a two‐dimensional fan filter so that the load is distributed. In the proposed configuration, a cardioid microphone is cascaded with an axially symmetric fan filter in a configuration that forms a single broadside beam. Another configuration forms a single beam in the endfire direction by cascading the bidirectional microphone to a diagonally symmetric fan filter. Deterioration of the pressure‐gradient microphone is compensated for by the two‐dimensional FIR filter. As a result, the directional characteristics of the pressure‐gradient microphone are reflected in the array microphone and a sharp directivity not dependent on the frequency is obtained over a wide frequency range. © 2006 Wiley Periodicals, Inc.
