Circular Polarizers Enhance Visibility of Endothelium in Specular Reflection Biomicroscopy (1985)

A simple and inexpensive technique for enhancing the visibility of corneal endothelial cells in specular reflection biomicroscopy involves the insertion of a circular polarizer in front of the patient's eye, intersecting both the incident and reflected light beams. This filter significantly reduces the glare from the epithelium and enables more comfortable and clearer viewing of the endothelial cells.
A Novel Common Power Factor Correction Scheme for Homes And Offices (2005)

This paper explores the approach of having a common Power Factor Correction circuit for domestic and commercial loads. This leads to lower harmonic distortion without the need to install (expensive) active rectifiers in each end-user device. The need for power-factor correction as well as a number of design options is discussed in this paper. The design and cost estimation of a common Power Factor Correction scheme and some reliability issues are discussed.
Self-protection of Pseudomonas syringae pv. "tabaci" from its toxin, tabtoxinine-beta-lactam (1987)

An extracellular toxin, tabtoxinine-beta-lactam (T beta L), is produced by Pseudomonas syringae pv. "tabaci." This toxin irreversibly inhibits its target, glutamine synthetase; yet P. syringae pv. "tabaci" retains significant amounts of glutamine synthetase activity during toxin production in culture. As part of our investigation of the self-protection of P. syringae pv. "tabaci," we compared the effects of T beta L on Tox+ (T beta L-producing, insensitive to T beta L) and Tox- (T beta L nonproducing, sensitive to T beta L) strains. The extent of protection afforded to the Tox- strain when induced to adenylylate glutamine synthetase was tested. We concluded that an additional protection mechanism was required. A detoxification activity was found in the Tox+ strain which opens the beta-lactam ring of T beta L to produce the inactive, open-chain form, tabtoxinine. Whole cells of the Tox+ strain incubated for 24 h with [14C]T beta L (0.276 mumol/3 X 10(10) cells) contained [14C]tabtoxinine (0.056 mumol), and the medium contained T beta L (0.226 mumol). Extracts of spheroplasts of the Tox+ stain also converted T beta L to tabtoxinine, whereas extracts of the Tox- strain did not alter T beta L. The conversion was time dependent and stoichiometric and was destroyed by boiling for 30 min or by the addition of 5 mM EDTA. Penicillin, a possible substrate and competitive inhibitor of this lactamase activity, inhibited the conversion of T beta L to tabtoxinine. Periplasmic fluid did not catalyze the conversion of T beta L.
Migrating from Virtualization to Dockerization in the Cloud: Simulation and Evaluation of Distributed Systems (2016)

Virtualization is the nucleus of the cloud computing for providing its services on-demand. Cloud-based distributed systems are predominantly developed using virtualization technology. However, the requirement of significant resources and issues of interoperability and deployment make it less adopt- able in the development of many types of distributed systems. Dockerization or Docker Container-based virtualization has been introduced in the last three years and gaining popularity in the software development community. Docker has recently introduced its distributed system development tool called Swarm, which extends the Docker Container-based system development process on multiple hosts in multiple clouds. Docker Swarm-based containerized distributed system is a brand new approach and needs to be compared with the virtualized distributed system. Therefore, this paper presents the simulation and evaluation of the development of a distributed system using virtualization and dockerization. This simulation is based on Docker Swarm, VirtualBox, Ubuntu, Mac OS X, nginx and redis. To simulate and evaluate the distributed system in the same environment, all Swarm Nodes and Virtual Machines are created using VirtualBox on the same Mac OS X host. For making this evaluation rational, almost similar system resources are allocated to both at the beginning. Subsequently, similar servers nginx and redis are installed on the Swarm Node and Virtual Machine. Finally, based on the experimental simulation results, it evaluates their required resources and operational overheads; thus, their performance and effectiveness for designing distributed systems.
Image denoising algorithm via spatially adaptive bilateral filtering (2013)

The classical bilateral filtering algorithm is a non-linear and non-iterative image denoising method in spatial domain which utilizes the spatial information and the intensity information between a point and its neighbors to smooth the noisy images while preserving edges well. To further improve the image denoising performance, a spatially adaptive bilateral filtering image deonoising algorithm with low computational complexity is proposed. The proposed algorithm takes advantage of the local statistics characteristic of the image signal to better preserve the edges or textures while suppressing the noise. Experiment results show that the proposed image denoising algorithm achieves better performance than the classical bilateral filtering image denoising method.
A media stream processing of VoIP media gateway (2004)

The converged network consisted of PSTN, IP, 2G and 3G-mobile will allow many different communications systems to interoperates so that users will be able to share data and voice services. One of the key elements is the media gateway, which provides conversion of streamed media formats such as voice and manages the transfer of information between the different networks. The VoIP media gateway supports transcodec that converts between speech codecs of each network and can improve the speech quality of intercommunication among different networks. Our VoIP media gateway adopted direct network interface to eliminate bottlenecks between host processor and DSPs and need not use packet processor because DSP is in charge of network interface. This paper described the architecture of converged network applied to VoIP media gateway, the architecture and the functions of media gateway and the DSP's media processing scheme.
On the Benefit of Inventory‐Based Dynamic Pricing Strategies (2009)

We study the optimal pricing and replenishment decisions in an inventory system with a price‐sensitive demand, focusing on the benefit of the inventory‐based dynamic pricing strategy. We find that demand variability impacts the benefit of dynamic pricing not only through the magnitude of the variability but also through its functional form (e.g., whether it is additive, multiplicative, or others). We provide an approach to quantify the profit improvement of dynamic pricing over static pricing without having to solve the dynamic pricing problem. We also demonstrate that dynamic pricing is most effective when it is jointly optimized with inventory replenishment decisions, and that its advantage can be mostly realized by using one or two price changes over a replenishment cycle.
All digital compensation scheme for spur induced transmit self-jamming in multi-receiver RF frond-ends (2012)

In radio receivers employing diversity reception, receiver LO frequencies are closely separated. Different LO frequencies can couple through the substrate to the nonlinear components in the phase locked loops thus generating spurs. Such a spur, if it falls nearby the local transmit frequency, can inadvertently demodulate the strong local transmit signal and hence degrade the received SNR severely. In this paper, we investigate a novel method of compensating for transmitter self-jamming by carefully mimicking this mechanism in the received signal path and thus allowing cancellation. It has been shown that with certain simplifying assumptions one can realistically cancel the spur-induced transmit self-jamming interference. We outline the theoretical feasibility of this approach and then setup an RF test-bench to demonstrate these ideas on actual RF chipsets. Performance results from prototype measurements are reported.
Construction of Malaria Multivalent Recombinant DNA Vaccine with Isocaudamer Technique (1999)

With the isocaudamers which have different recognition sequences and produce compatible cohesive ends,chimeric multi epitope Plasmodium falciparum DNA vaccines including the multiplication of the single copy epitope and the tandem linkage of different kinds of epitopes were flexibly constructed.A specific B cell response was detected by ELISA after the immunization of BALB/c mice with the chimeric antigen and demonstrated the usefulness of this strategy of constructing multi epitope DNA vaccines.
A New Degradable Controlled Release Device for Treatment of Periodontal Disease: In Vitro Release Study (1990)

The substantivity of a drug in the periodontal pocket is an important factor determining its effect on the subgingival flora. Therefore, one of the predominant factors in the development of a sustained release delivery device is the ability to control the rate of release of the drug. Previous studies have demonstrated the advantages of the local sustained release of chlorhexidine from nondegradable devices in the treatment of periodontal diseases. The aim of this study was to develop a degradable sustained release device composed of a cross-linked protein containing chlorhexidine as the therapeutic agent. The in vitro release profile of chlorhexidine from the degradable films was altered by the amount of chlorhexidine incorporated into the film, by the cross-link density of the polymer, and by the chlorhexidine salt used. The chlorhexidine in the final pharmaceutical preparation did not lose its antibacterial activity as was shown in an in vitro antibacterial test. This work demonstrates that the release of chlorhexidine from a degradable delivery system and the degradation of the matrix can be controlled by variation in the formulation. This presents a new dental drug delivery system that can be used as an adjunct in the treatment of periodontal diseases in the future. These studies enable us to choose the pharmaceutical formulations for clinical trials to be conducted testing the efficacy of this treatment modality.
Bioconjugated and Cross-Linked Bionanostructures for Bifunctional Immunohistochemical Labeling (2012)

The present study describes the development and use of a new bioconjugate combining targeted quantum dot labeling with an immunoperoxidase method and explores whether these bioconjugates could specifically and effectively label Cu/Zn superoxide dismutase (SOD1). The new bioconjugate is designed for the examination of samples both under fluorescent and bright-field microscopy at the same time. For this purpose chlorobis(2-2'-bipyridyl) methacryloyl tyrosine-ruthenium(II) and bis (2-2'-bipyridyl) methacryloyltyrosine-methacryloyltryptophan-ruthenium (II) photosensitive monomers and photosensitive poly(Bis (2-2'-bipyridyl)) methacryloyltyrosine-methacryloyltryptophan-ruthenium(II) were synthesized and characterized. The anti-SOD1 antibody and horseradish peroxidase (HRD) conjugated quantum dots were prepared by using this polymer. The anti-SOD1 antibody and HRD conjugated quantum dots were used in labeling and imaging of SOD1 in rat liver sections. Quantum dot particles were observed as a bright fluorescence in their specific binding locations inside the hepatocytes. The HRD-diaminobenzidine reaction product was observed as brown-colored particles at the same locations under bright-field microscopy. Structural details of the tissue sections could be examined at the same time. The conjugation protocol is simple; the bioconjugate is applicable for efficient cell labeling and can be adapted for imaging of other targets in different tissues. Also, the prepared nanobioconjugates have mechanic stability and can be used for a long period.
!Kung Bushman Religious Beliefs (1962)

Opening Paragraph My purpose in this paper is to describe some of the religious beliefs held currently by the !Kung Bushmen of the interior bands of the Nyae Nyae region of South West Africa. I shall limit the paper to a description of their concepts of the gods, the problem of evil, supplication, the spirits of the dead, and the ceremonial curing dance, but leave for another paper a more detailed account of medicine men, how they become medicine men, and more about their practices and beliefs. We gathered the information which I present principally on our expeditions of 1952–3 and 1955.

Vinculin is required for cell polarization, migration, and extracellular matrix remodeling in 3D collagen (2015)

Vinculin is filamentous (F)-actin-binding protein enriched in integrin-based adhesions to the extracellular matrix (ECM). Whereas studies in 2-dimensional (2D) tissue culture models have suggested that vinculin negatively regulates cell migration by promoting cytoskeleton-ECM coupling to strengthen and stabilize adhesions, its role in regulating cell migration in more physiologic, 3-dimensional (3D) environments is unclear. To address the role of vinculin in 3D cell migration, we analyzed the morphodynamics, migration, and ECM remodeling of primary murine embryonic fibroblasts (MEFs) with cre/loxP-mediated vinculin gene disruption in 3D collagen I cultures. We found that vinculin promoted 3D cell migration by increasing directional persistence. Vinculin was necessary for persistent cell protrusion, cell elongation, and stable cell orientation in 3D collagen, but was dispensable for lamellipodia formation, suggesting that vinculin-mediated cell adhesion to the ECM is needed to convert actin-based cell protrusion into persistent cell shape change and migration. Consistent with this finding, vinculin was necessary for efficient traction force generation in 3D collagen without affecting myosin II activity and promoted 3D collagen fiber alignment and macroscopical gel contraction. Our results suggest that vinculin promotes directionally persistent cell migration and tension-dependent ECM remodeling in complex 3D environments by increasing cell-ECM adhesion and traction force generation.
Acellular Dermal Matrix (AlloDerm): New Material in the Repair of Stoma Site Hernias (2005)

Parastomal hernias are a common complication after ileostomy or colostomy formation and can lead to complications, such as intestinal obstruction and strangulation. When a parastomal hernia presents, repair of the defect can pose a challenge to the surgeon to choose a repair that both reduces complications and recurrence rates. We present three cases of parastomal hernia repair using acellular dermal matrix (AlloDerm) as reinforcement to the primary hernia repair. We prospectively followed three patients who presented with parastomal hernia after ostomy formation in 2001-2002. The patients underwent repair of the parastomal hernia using primary fascial repair with reinforcement using AlloDerm as an on-lay patch. Two patients were followed for 6 months and 1 year, respectively, and remained hernia-free. One patient presented 8 months later with symptoms of intestinal obstruction that were relieved by nasogastric tube decompression and bowel rest. The patient subsequently returned 3 months later with intestinal obstruction and recurrent parastomal hernia that necessitated an operation for relocation of the stoma and repeat hernia repair. Repair of parastomal hernias using AlloDerm acellular dermal matrix as a substitute for a synthetic graft showed resilience to infection and, more importantly, tolerated exposure in an open wound without having to be removed. Larger studies with longer follow-up are needed to see if this material reduces the incidence of hernia recurrence.
Tracking in clutter with nearest neighbor filters: analysis and performance (1996)

The measurement that is "closest" to the predicted target measurement is known as the "nearest neighbor" (NN) measurement in tracking. A common method currently in wide use for tracking in clutter is the so-called NN filter, which uses only the NN measurement as if it were the true one. The purpose of this work is two fold. First, the following theoretical results are derived: the a priori probabilities of all three data association events (updates with correct measurement, with incorrect measurement, and no update), the probability density functions (pdfs) of the NN measurement conditioned on the association events, and the one-step-ahead prediction of the matrix mean square error (MSE) conditioned on the association events. Secondly, a technique for prediction without recourse to expensive Monte Carlo simulations of the performance of tracking in clutter with the NN filter is presented. It can quantify the dynamic process of tracking divergence as well as the steady-state performance. The technique is a new development along the line of the recently developed general approach to the performance prediction of algorithm with both continuous and discrete uncertainties.
Somatotopic mapping of the human primary motor cortex with functional magnetic resonance imaging (1995)

We applied functional magnetic resonance imaging (FMRI) to map the somatotopic organization of the primary motor cortex using voluntary movements of the hand, arm, and foot. Eight right-handed healthy subjects performed self-paced, repetitive, flexion/extension movements of the limbs while undergoing echo-planar imaging. Four subjects performed movements of the right fingers and toes, while the remaining subjects performed movements of the right fingers and elbow joint. There was statistically significant functional activity in the left primary motor cortex in all subjects. The pattern of functional activity followed a topographic representation: finger movements resulted in signal intensity changes over the convexity of the left motor cortex, whereas toe movements produced changes either at the interhemispheric fissure or on the dorsolateral surface adjacent to the interhemispheric fissure. Elbow movements overlapped the more medial signal intensity changes observed with finger movements. Functionally active regions were confined to the cortical ribbon and followed the gyral anatomy closely. These findings indicate that FMRI is capable of generating somatotopic maps of the primary motor cortex in individual subjects.
Improvements in SLS Part Accuracy (2018)

SLS® part accuracy is influenced by a number ofmachine and material characteristics. Some of\nthe most significant sources of error are associated with laser beam positioning (static and\ndynamic) on the part bed surface and uncertainty in the calibration factors used to compensate\nfor material shrinkage and growth as well as the finite width ofthe laser beam. Another source of\nerror is the minimum resolution of the process, which is a dependent on the particle size and\nshape ofthe material. In this presentation, technical background on these issues will be provided.\nIn addition, part data obtained with a number of SLS materials demonstrating improved accuracy\nobtained through machine modifications and improved calibration methods will be described.
J.E.T.T. Classifieds (1989)

publicized the results of a survey on the Foreign Language Teaching Profession.The survey, conducted with the endorsement and cooperation of the American Council on the Teaching of Foreign Languages (ACTFL) and the financial support of the Louis F. Capalbo Endowment Fund, concludes that male teachers of foreign languages are much more likely to be clustered in higher income brackets than are their female counterparts, both before and after adjustments for differences in years of experience.The authors also report that income is substantially influenced by several other factors, such as number of students in the institution (the greater the number, the higher the income), where the institution is located (suburban institutions pay the highest incomes), and geographic area of the country (Northeast is highest and South is lowest).
Intake-Valve Temperature and the Factors Affecting It (1997)

<div class="htmlview paragraph">Steady-state temperature measurements were made at two locations on the back surface of the intake valves of one of the cylinders of a Saturn 1.9-L DOHC engine. The temperature locations were such that in the upstream location the thermocouple is subjected to the impingement of the fuel spray during the injection process, whereas in the downstream location the thermocouple is out of the main fuel spray. The measured intake valve temperature at the upstream location was significantly lower than that at the downstream location, which was attributed to the spray cooling effect. The intake valve temperature was found to increase with increasing load, speed and coolant temperature. As the air-fuel ratio changes the valve temperature exhibits a maximum at near stoichiometric compositions, which is attributed to convective heat transfer from the backflow of combustion gases during the valve-overlap period. Intake valve temperature correlations were developed with excellent predictive capabilities. Coolant temperature was the single most important correlating variable of the intake valve temperature, followed by engine speed and air-fuel ratio.</div>
Quantitative detection of mutant alleles of the K-ras gene with minor groove binder-conjugated fluorogenic DNA probes (2004)

Tumor-specific point mutations are stable biomarkers compared with tumor-specific mRNA expression, and are therefore useful to detect occult tumor cells. These mutations have never been used for real-time quantitative polymerase chain reaction (RQ-PCR) assays, because the ability of conventional probes to discriminate between wild-type and mutant alleles is poor. Recently, DNA probes with conjugated minor groove binder (MGB) have been developed. Because of their high melting temperature, these probes achieve high performance in detecting single nucleotide mismatches. Using the MGB technology, we developed a new RQ-PCR system for detecting occult tumor cells in patients with colorectal cancer (CRC), targeting K-ras point mutations. Sixteen MGB-conjugated DNA probes were designed for all previously reported K-ras mutations. The performance of these probes was examined with plasmid DNAs into which K-ras point mutations had been inserted, 32 cancer cell lines and 338 lymph nodes obtained from 15 CRC patients. Fifteen of the 16 MGB probes designed were useful for accurate quantitative assessment, and achieved high sensitivity (1/10(4)-10(5) background cells) and high reproducibility (coefficients of variation <10%). Performance in discriminating single nucleotide mismatches was superior for MGB probes compared with non-MGB probes. We detected a micrometastasis (5.85/10(4) cells equivalent) in one (0.9%) of 110 lymph nodes obtained from 6 patients with K-ras mutations. There was no true false-positive result in 209 lymph nodes obtained from 9 patients without K-ras mutations. The MGB RQ-PCR assay targeting K-ras mutations is an accurate quantitative method for detecting occult tumor cells in CRC.
