Experimental verification of image detection in highly scattering media using antenna properties of optical heterodyne microscope scheme (1990)

The spatial resolution capability for image detection in the presence of strong scattering inside a medium is verified by virtue of the antenna properties of the optical heterodyne method. The image formation of test microletters in a highly scattering solution is successfully achieved using an optical heterodyne scanning microscope.
A broader view (2005)

Trying to predict the future has always been a risky business. But if we want to be in control of marketing brands and products, taking an intelligent stab at future packaging is well in order.
GPGS (1977)

GPGS is a subroutine package offering powerful and versatile support for passive and interactive vector graphics, for time-sharing, batch, and stand-alone minicomputer systems. The package is computer, language, and operating system, as well as display device independent. Its key purpose is to allow for transportabiliit of programs and programmers by providing easy to learn, high level features. The applications programmer writes his program once and then executes it on any supported graphics equipment without recompiling or relinking it. Device-independence was implemented by dividing GPGS into a device-independent part invoked by the applications programmer, and internal, "device drivers", one per display device. Like the GSPC "Core System" whose design it influenced, GPGS is a general purpose package. It has a subset of graphics facilities to handle output of line and character primitives with attributes such as line style and character size, and input from interaction tools such as lightpens, keyboards, valuators, and function keys. It also supports 2D and 3D viewin transformationss for clipping and window to viewport mapping, and coordinate transformations.Unlike the GSPC Core System, GPGS also includes a set of basic features for modelling objects which allows definition of device independent masters called seudo picture segment. These are distinguished from normal, device (DPU) dependent pictur segments into which primitives and their attribute-value settings are ordinarily compiled. These masters may be instanced subject to affine transformations (translate, rotate, and scale) to create a typical master-instance hierarchy. The hierarchy may be stored in a disk based library or compiled into a normal picture segment for output to a display device.The images of objects stored in device dependent picture segments may be transformed on the display surface by v port (image) transformations. These typically allow use of hardware transformation capabilities for dragging or tumbling object images.Host/satellite graphics is accommodated by having the device independent part of GPGS in the host and splitting the device drivers across host and satellite. At the source code level it therefore makes no difference on which.configuration a program will be executed.Among the existing implementations are versions written in assembler for the IB 360/370 and the PDP 11, in both stand-alone and satellite mode, and under a variety of operating systems. They support plotters, storage tubes, and high performance refresh displays. FORTRAN based implementations exist for the Univac 1108, the PDP 10, and a Harris minicomputer.
Job Satisfaction and its Relationship to Job Characteristics of School Foodservice Dietitians (1993)

The purposes of this study were to: (a) measure the levels of job satisfaction with five facets of a job: the work itself, promotion, pay, supervision and co-workers and (b) investigate relationships between job characteristics and job satisfaction levels of the dietitians in school foodservice. Subjects consisted of 151 dietitians, with 91 in Seoul and 60 in KyoungKi-Do. The survey form was developed on modifying Job Descriptive Index developed by Smith, Kendall, Hulin and Job Characteristics Inventory developed by Sims, Szilagy, Keller. The responding rate was 81.7%. Data were analyzed for frequencies, means, t-test, ANOVA, Pearson correlation and multiple regression using SPSS PC Package. The results of this study were as follows: 1) Less than a half of the sample(40.9%) were 31 to 35 years, married were 62% and junior college graduates were 33.9%. 2) A striking majority of the respondents(81.7%) ranked work itself as the the most important aspect of their jobs. 3) The dietitians were the most satisfied with work itself, then supervision, co-workers, wage and promotion in decreasing order. 4) In relations of demographic factors to the job satisfaction, satisfactions with wage and co-workers were found significantly related to education. 5) Task identity was the most prevalent job characteristics. 6) The for the multiple regression model was 0.26, indicating that 26% of the variance in job satisfaction could be accounted for the job characteristics. This model showed that friendship of job characteristics made the greatest contributions. The second was variety and the third was dealing with others. Especially dealing with others was negatively related to job satisfaction.
Probe Station Placement for Fault Diagnosis (2007)

Probe stations are specially instrumented nodes from where probes can be sent to monitor the network. Probe station locations affect probing efficiency, monitoring capability, and deployment cost. We present probe station selection algorithms and aim to minimize the number of probe stations and make the monitoring robust against failures in a deterministic as well as a non-deterministic environment. We provide experimental evaluation of the proposed algorithms through simulation results.
Ultra-wideband microwave components fabricated using low-cost aerosol-jet printing technology (2015)

In this paper, ultra-wideband RF/Microwave components fabricated using a low-cost aerosol-jet printing technology are demonstrated on a 50 μm thick Kapton film. The demonstrated RF/Microwave components include a four-stage Wilkinson power divider and a novel planar quad Archimedean spiral true-time delay line. The printed power divider has achieved a bandwidth of 2 to 20 GHz with typical 2 dB insertion loss, greater than 25 dB return loss, and better than 25 dB isolation performance across the majority of the band. The printed delay line has demonstrated 2 ns true time delay with excellent delay flatness across the entire band. The performances of the printed RF/Microwave components are comparable to those of semiconductor based monolithic microwave integrated circuits (MMIC).
Z-R Relationship from the Particle Size and Velocity (Parsivel) Optical Disdrometer and its Application in Estimating Areal Rainfall (2008)

In order to improve the precision of Radar rainfall estimates, the Parsivel was used for observation of rain drop spectra over Leizhou Peninsula from July to August, 2007. A total of 18070 size distributions were analyzed and the Z-R relationship of convective precipitation and mixtures of convective and stratocumulus cumulogenitus precipitation were obtained. These Z-R values were used for estimating areal rainfall and then compared with observations from automatic weather station. Cases with convective and mixtures of convective and stratocumulus cumulogenitus precipitation were selected for the evaluation. The precipitation studies were also used to evaluate the precision of the PARSIVEL measurements as compared to the rainfall data of automatic weather station.

Arterial branching in various parts of the cardiovascular system (1982)

Angiographic pictures of vascular beds in various parts of the cardiovascular system were analyzed to study the geometrical structure of arterial bifurcations. The sites of arterial bifurcations were enlarged individually, and measurements were made of the branching angles and branch diameters at each site. Results from various parts of the cardiovascular system of man, and some from rabbit and pig, were compared with each other. The measurements were also compared with "optimum" values of branching angles and branch diameters which have been predicted by various theoretical studies. In general the measurements were found to give support to the theoretical premise that branching angles and branch diameters in the cardiovascular system are dictated by certain optimality principles which aim to maximize the efficiency of the system in its fluid-conducting function. In some parts of the system, however, the measured angles and diameters were found to be decidedly lower than those predicted by theory.

Yangian-Invariant Scattering Amplitudes in Supersymmetric Chern-Simons Theory (2010)

We propose a generating function for scattering amplitudes of N=6 supersymmetric-Chern-Simons theory, which parallels a recent work on N=4 supersymmetric-Yang-Mills theory by Arkani-Hamed et al. Our result suggests that the scattering amplitudes of the supersymmetric-Chern-Simons theory exhibit Yangian invariance.

Mechanisms of Cellular Effects Directly Induced by Magnetic Nanoparticles under Magnetic Fields (2017)

The interaction of magnetic nanoparticles (MNPs) with various magnetic fields could directly induce cellular effects. Many scattered investigations have got involved in these cellular effects, analyzed their relative mechanisms, and extended their biomedical uses in magnetic hyperthermia and cell regulation. This review reports these cellular effects and their important applications in biomedical area. More importantly, we highlight the underlying mechanisms behind these direct cellular effects in the review from the thermal energy and mechanical force. Recently, some physical analyses showed that the mechanisms of heat and mechanical force in cellular effects are controversial. Although the physical principle plays an important role in these cellular effects, some chemical reactions such as free radical reaction also existed in the interaction of MNPs with magnetic fields, which provides the possible explanation for the current controversy. It is anticipated that the review here could provide readers with a deeper understanding of mechanisms of how MNPs contribute to the direct cellular effects and thus their biomedical applications under various magnetic fields.

Application of DLP™ Technology to Digital Electronic Cinema—A Progress Report (1998)

In the entertainment industry's quest for the “suspension of disbelief,” two primary sensory stimuli have been engaged: sight and sound. Since the advent of digital audio, a number of new multitrack digital sound formats have appeared in the motion picture industry, all in an attempt to achieve the ultimate audio experience. However, visual presentation has not advanced at the same pace as the aural experience. Many problems associated with conventional motion picture presentation and distribution can be overcome through a digital form of delivery. The missing link, however, has been an electronic display system that delivers cinema-quality images. Certainly the ultimate achievement in electronic projected image quality would be to match or exceed that of motion picture film. — Texas Instruments is studying the possible application of DLP <sup xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">TM</sup> technology to electronic cinema. This effort has involved a close working relationship with the motion picture industry to assess DLP performance from technical and artistic perspectives. Knowledge gained from this process has led to improvements in DLP technology that may someday lead to a DLP-based cinema application. This paper addresses some of the advances in image quality made in the quest to achieve the ultimate cinematic experience.
A Comparison between Hot Liquid Water and Steam Fractionation of Corn Fiber (2001)

Dried, milled corn fiber (0.2−0.5 kg) was fractionated by treatment with either hot liquid water (3−4 kg) at low solids loadings (5−10%) or steam (0.1−0.4 kg) at high solids loadings (>50%) at 210−220 °C for 2 min, using the same novel process equipment. Pentosan recovery and inhibition of yeast fermentation were evaluated and compared. In addition, the reactivity of pretreated fiber with respect to enzymatic hydrolysis was evaluated using a simultaneous saccharification and fermentation (SSF) system consisting of β-glucosidase-supplemented Trichoderma reesei cellulase together with fermentation by Saccharomyces cerevisiae. Greater solubilization was achieved at 215 °C with hot liquid water at 5% solids loading than with steam at 70% solids loading (54% solubilization vs 37%). The lignocellulosic residue from this hot liquid water fractionation was enriched in glucan. Conversely, the steam fractionation caused no significant change in the fraction of glucan in the residue, relative to the feed material. In both cases, the pentosan fraction of the lignocellulosic residue was reduced, with the steam fractionation resulting in a larger reduction of these carbohydrates. Steam fractionation (70% solids loading) resulted in much lower pentosan recovery (as monosaccharides after posthydrolysis) than fractionation with hot liquid water at 5% solids loading (40% vs 82%). In both cases, the majority of the solubilized pentosans existed as oligomers (>80%). These recoveries indicate that the monosaccharides are protected while in the form of oligomers because recoveries of largely oligomeric carbohydrates are higher than recoveries of monomeric xylose pretreated under similar conditions. The lignocellulosic residues from fractionation at 215 °C with hot liquid water at 5% solids loading and with steam at 70% solids loading were both reactive to enzymatic hydrolysis, exhibiting 86 and 90% conversion of glucan to ethanol respectively vs 64% conversion with untreated corn fiber, obtained by SSF at an enzymatic loading of 15 FPU cellulase/g of cellulose. The liquid product (extract) from the hot liquid water fractionation did not inhibit the final yield of glucose fermentation by S. cerivisiae, while the liquid product from the steam fractionation did.
Charge transfer and transport in DNA (1998)

We explore charge migration in DNA, advancing two distinct mechanisms of charge separation in a donor (d)-bridge ([Bj])-acceptor (a) system, where [Bj] = B1,B2, . , BN are the N-specific adjacent bases of B-DNA: (i) two-center unistep superexchange induced charge transfer, d*[Bj]a --> d[Bj]a+/-, and (ii) multistep charge transport involves charge injection from d* (or d+) to [Bj], charge hopping within [Bj], and charge trapping by a. For off-resonance coupling, mechanism i prevails with the charge separation rate and yield exhibiting an exponential dependence approximately exp(-betaR) on the d-a distance (R). Resonance coupling results in mechanism ii with the charge separation lifetime tau approximately Neta and yield Y approximately (1 + Neta)-1 exhibiting a weak (algebraic) N and distance dependence. The power parameter eta is determined by charge hopping random walk. Energetic control of the charge migration mechanism is exerted by the energetics of the ion pair state dB1+/-B2 . BNa relative to the electronically excited donor doorway state d*B1B2 . BNa. The realization of charge separation via superexchange or hopping is determined by the base sequence within the bridge. Our energetic-dynamic relations, in conjunction with the energetic data for d*/d- and for B/B+, determine the realization of the two distinct mechanisms in different hole donor systems, establishing the conditions for "chemistry at a distance" after charge transport in DNA. The energetic control of the charge migration mechanisms attained by the sequence specificity of the bridge is universal for large molecular-scale systems, for proteins, and for DNA.

Precise Frequency Comparison System Using Bidirectional Optical Amplifiers (2009)

Precise frequency comparisons are becoming more urgent given the recent rapid progress in next-generation frequency standards. This paper describes a new type of bidirectional optical amplifier that overcomes the fiber loss limits that have prevented accurate frequency comparisons between widely separated places; such comparison is realized by bidirectionally transmitting wavelength-division-multiplexed (WDM) signals along a single fiber. The proposed optical amplifier has an optical isolator in each two-way channel divided by wavelength filters to suppress the optical reflection that causes amplification instability. The additional insertion optical loss due to this method is about 1.5 dB. The optical gain greater than 30 dB is obtained for both signals with good optical isolation of 65 dB. A radio-frequency reference signal can directly be sent by simple intensity modulation and direct detection (IM-DD) devices in the 1550-nm region widely used in telecommunication networks. Phase comparisons of the received signals and the frequency standards at each terminal are used for frequency comparisons. The amplifier is tested in the field using two hydrogen masers. A 120-km fiber with loss of 52.5 dB is used to connect the National Metrology Institute of Japan (NMIJ) to the University of Tokyo. Because of this loss, an amplifier is needed to realize sufficient receiving power. The frequency stability of the system with a 10-MHz direct transmission is evaluated by returning the optical signal from a halfway point [55 km from the NMIJ] where the amplifier is installed. The result is 2.6 × 10 <sup xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">-16</sup> (Allan deviation) with the averaging time of 7 × 10 <sup xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">4</sup> s.

A review of current raw SAR data compression techniques (2002)

Synthetic aperture radar (SAR) is a sophisticated technique of all-weather radar imaging capable of producing fine detailed images from a moving platform. When such a radar is placed on-board a satellite, compression of the raw SAR signal is necessary to reduce the huge amount of collected data for the downlink to a ground station within the bandwidth constraints. This is further exasperated by new high resolution imaging radars currently in development capable of producing significantly more data. This paper presents a review of current raw SAR data compression techniques which are classified into three different categories according to the method of quantization, scalar or vector, and to the domain of compression.
