Relationships between optical aggregometry (type born) and flow cytometry in evaluating ADP‐induced platelet activation
Authors: Sbrana Silverio , Della Pina Francesca , Rizza Antonio , Buffa Manuela , De Filippis Rossella , Gianetti Jacopo , Clerico Aldo
Published: July 2007

Background:

Platelet response to activating agents is used to monitor the efficacy of anti‐aggregation therapies. The aim of our study has been to demonstrate the existence of relationships between early events of ADP‐induced platelet activation, measured by flow cytometry and platelet‐rich plasma aggregation, quantified by optical aggregometry.

Methods:

We evaluated peripheral blood of 12 donors. The following parameters were quantified by cytometry after stimulation with adenosine diphosphate (ADP) (0.5, 1, 2, 5, 10, 20 μM): CD62P (P‐selectin) and PAC‐1 expression, and cytosolic Ca2+ mobilization. Aggregation was measured by optical aggregometry. We also studied 13 patients, undergoing coronary stenting, treated with aspirin (before procedure) or with aspirin plus clopidogrel (after procedure). We evaluated CD62P and PAC‐1 expression, aggregation, and vasodilator‐stimulated phopshoprotein phosphorylation (platelet reactivity index, PRI).

Results:

Flow procedures were more sensitive than aggregometry, with a lowest interindividual variability. Linear relationships existed in donors between CD62P expression and Ca2+ mobilization (P < 0.0001), and between aggregation and Ca2+ mobilization (P < 0.0001). Linear relationships existed between aggregation and CD62P expression, as percentage (P < 0.0001), or relative fluorescence intensity (RFI) (P < 0.0001). Exponential equations related aggregation and PAC‐1 expression, as percentage (P < 0.0001), or RFI (P < 0.0001). Linear relationships between aggregation and CD62P expression (as percentage) existed in the patients before (P = 0.0022) and after procedure (P = 0.0020). Exponential relationships between aggregation and PAC‐1 expression (as percentage) existed before (P = 0.0012) and after procedure (P = 0.0024). Linear correlations related aggregation response predicted on CD62P expression, and measured aggregation inhibition after clopidogrel (P = 0.0013) as well as predicted aggregation and PRI inhibition (P = 0.0031).

Conclusions:

Tight relationships between aggregation and cytometric quantification of platelet markers in whole blood, in particular CD62P, allow to predict aggregation response to ADP from flow data in patients treated with aspirin alone or with aspirin plus clopidogrel. © 2007 Clinical Cytometry Society
A method for increasing number of co‐channel users in spread spectrum multiple access communication systems
Authors: Sugiyama Hisayoshi , Amemiya Yoshifumi
Published: July 2007

A method for increasing the number of co‐channel users in direct sequence spread spectrum multiple access (SSMA) communication systems is presented. The effect of band limit on SN ratio, autocorrelation, and mutual correlation of PN signals is studied analytically in direct sequence SSMA. The result is that the number of co‐channel users can be increased by 60% with little effect on acquisition of PN signals by setting the bit rate about three times larger than that of usual systems.
Lens applicator for localized microwave hyperthermia
Authors: Nikawa Yoshio , Miyashita Teruo , Mori Shinsaku , Kikuchi Makoto , Sekiya Tomio
Published: July 2007

Hyperthermia is now recognized as an effective means for cancer therapy, and many reports on the irradiation of biological subjects by electromagnetic waves to produce dielectric heating and hyperthermia have been reported. Although it is desirable in hyperthermia selectively to heat the cancer tissue, it is difficult to estimate the heat distribution in the subject owing to insufficient analysis of the electromagnetic field distribution in the irradiated subject. At present it is not yet possible to control the temperature distribution in the biological subject. In electromagnetic wave hyperthermia, microwaves are effective from the viewpoint of efficiency or selective heating. On the other hand, it is difficult to heat a cancer in deep tissue because of reduced penetration of the microwaves into the subject. This paper shows experimentally and by theoretical analysis, using a microwave lens geometrically designed to produce a focused cylindrical wave as the applicator, that selective heating is possible for tissue 10 to 40 percent deeper than with planar wave. It is shown that the microwave lens applicator is effective for the heating of biological tissues.
A new method of circuit analysis and central trees of a graph
Authors: Kajitani Yoji , Kawamoto Tatsuya , Shinoda Shoji
Published: July 2007

As a method of analysis for the general linear lumped circuit including active elements, this paper proposes a new method called the primal dual analysis, in which the backward parts of the cut‐set and tieset analysis are applied in two steps. the problem to determine the minimum number of independent variables for the analysis is formulated from the graph‐theoretic viewpoint. the essential difference between the proposed method and the traditional methods is described from the viewpoint of minimizing the required set of variables. In the case of passive circuits, the problem of determining the minimum independent variables in the primal dual analysis is seen to be reduced to the problem of determining the central tree of the graph. This problem is known to be difficult to solve. In the latter part of this paper, some results for this problem, obtained by the authors up to present, are described.
Usage characteristics of detour routes in store‐and‐forward switching networks
Authors: Komatsu Masaharu , Mayeda Wataru
Published: July 2007

This paper discusses characteristics of detour routes in store‐and‐forward switching networks for the traffic route assignments one of which is obtained by the optimum route assignment theorem and the other the equal delay principle when message length is generally distributed. the optimum route assignment theorem gives necessary and sufficient conditions for the route assignment to have minimum average message or packet delay‐time over a whole network. the equal‐delay‐principle, which is widely employed in traffic control, can be considered as a theoretical base for determination of an adaptive route using estimated delay‐time. Both traffic assignments obtained by the optimum route assignment and equal delay principle use detour routes to reduce the delay caused by increase of traffic rate. This paper shows that regardless of line capacities and message (or packet) length distribution, the case of the optimum route assignment employs detour route at the smaller traffic rate than equal delay principle. Furthermore, this paper chooses one‐stage parallel route model to show how line capacities and coefficients of variation of message length influences usage of detour routes for these two methods.
A 64Kbit MOS dynamic RAM with auto/self refresh functions
Authors: Yamada Michihiro , Taniguchi Makoto , Kobayashi Toshifumi , Kumanoya Masaki , Nakano Takao
Published: July 2007

Until now, a refresh operation, which is necessary in using MOS dynamic RAMs, has made MOS dynamic RAMs more difficult to use compared with static RAMs. On the other hand, with advances in MOS dynamic RAMs, new refresh modes, i.e., automatic and self refresh modes, become available when a spare pin is applied to a refresh control signal. In 64Kbit MOS dynamic RAMs, pin 1 can be such a refresh control terminal if the substrate bias is generated on‐chip. Circuit considerations in accommodating the automatic and self refresh modes by pin 1 are discussed, with special attention given to the on‐chip refresh address counter and the timer used during the self refresh. A practical 64Kbit MOS dynamic RAM has been realized with the chip area increase of 1.6% and the standby current increase of 0.3 mA as the result of implementing the automatic and self refresh modes.
Differential detection of manipulated MSK signals with decision feedback
Authors: Kurokawa Akira , Yamada Takahiro , Harashima Hiroshi , Miyakawa Hiroshi
Published: July 2007

The types of manipulated MSK (Minimum Shift Keying) signals obtained by narrowing MSK band which are currently attracting attention include TFM (Tamed Frequency Modulation) and GMSK (Gaussian filtered MSK) signals. A new 2‐bit delay differential detection technique for these manipulated signals is proposed and its performance is compared with the conventional technology. In the proposed technique, a decision feedback circuit which controls the phase references of the delayed signals is used to reduce the intersymbol interference caused by the transmit and receive filters. the proposed technique is especially effective for manipulated MSK signals. Computer simulation results show that the proposed technique requires a smaller receive filter bandwidth and the bit error performance results in an improvement of 3 to 8 dB in the SN ratio compared with the conventional technique.
Mathematical expression of the load characteristics of microwave oscillators and the injection‐locking characteristics
Authors: Fukumoto Katsumi , Nakajima Masamitsu , Ikenoue Jun‐Ichi
Published: July 2007

Most studies of the behavior of oscillators are based on the oscillator model proposed by Van der Pol. This model, however, is inadequate for a detailed description of the load characteristics and injection‐locking operations of actual oscillators. an oscillator model is proposed which represents the load characteristics of actual oscillators much better than does the Van der Pol model and a method is presented for determining the parameters of this model. Using this model, the injection‐locking operation of a microwave oscillator based on the concept of a traveling wave is analyzed and a relation between the load characteristics and the injection‐locking characteristics is derived. This study serves as an example of evaluating the validity of the oscillator model used in the analysis. It would be possible to represent the oscillator characteristics with a few numerical values (as in FET's and transistors). the theory and analytical results are confirmed experimentally.
Multistructured optical IC elements by polymer thin films
Authors: Kato Isamu , Komatsu Masatoshi
Published: July 2007

Conventional thin film optical elements consist of optical waveguides placed transversely in one plane. A new type of multilayer optical circuit element consisting of stacked thin‐film optical waveguides is proposed using polymer films in which optical waveguides are formed by ultraviolet light. After fabrication of an optical waveguide, the resistivity to solvent of the thin film increases, and hence any number of layers can be stacked without affecting the lower layers. We fabricated two‐layer and three‐layer optical directional couplers. In the former, optical waveguides are created in each layer such that they cross to each other. In the latter an additional layer is inserted between the two layers containing the waveguides. the optical coupling in these directional couplers takes place in the direction of the film thickness. the film thickness of the middle layer is measured, and the dependence of the coupling coefficient on the crossing angle and the middle layer thickness is studied experimentally. It is pointed out that an optical directional coupler with an arbitrary degree of coupling is easily fabricated. Also studied are n‐way optical equal parts dividers.
Cancellation techniques of co‐channel interference in asynchronous spread spectrum multiple access systems
Authors: Kohno Ryuji , Hatori Mitsutoshi
Published: July 2007

A spread spectrum multiple access (SSMA) communication scheme employing asynchronous code‐multiplexing technique has been used in both mobile and satellite communication systems. One shortcoming of the SSMA system is the co‐channel interference due to the correlations among the pseudo noise (PN) sequences being used by multiple channels. Such co‐channel interference in the reception limits the number of channels that can share one common frequency band. Furthermore, there is a distant‐dependent problem of different received‐powers from different transmitters.

This paper describes a technique for cancelling the co‐channel interference in asynchronous SSMA systems. This technique does not treat the co‐channel interference as thermal noise. It considers the co‐channel interference as components that can be recreated at each receiver. If the correlations among the PN sequences of all the active channels become known, the co‐channel interference can be cancelled using the linear algebraic approach. As a result, a larger number of channels can share the same frequency band more efficiently. Further, if initial synchronization can be implemented then the distant‐dependent problem can be alleviated.
