Polymer Nanocomposite Thin Film Mirror for the Infrared Region (Preprint) (2007)

Thin film metal oxide coatings have been used commercially for electromagnetic filters from the UV to the infra red regions for over half a century. Deposition onto a substrate has typically been accomplished using vapor deposition techniques and more recently sol-gel methods. These coatings provide very good optical performance under abrasion, thermal cycles and variable humidity when applied on substrates with similar thermal and mechanical properties. When conventional metal oxide coatings are applied to flexible, relatively soft substrates such as polymers, mismatches in mechanical properties can reduce interfacial adhesion or accelerate mechanical failures. The authors recently developed anti-reflective optical filters utilizing self-assembled thin film polymer nanocomposites on polymer substrates using less than five discrete layers. This paper describes the first time demonstration of an IR mirror using fifteen discrete layers with an IR-reflectance that exceeds 90 percent at 1064 nm and transparent in the visible spectrum.
Multimodal Approach to Human-Face Detection and Tracking (2008)

The constructive need for robots to coexist with humans requires human-machine interaction. It is a challenge to operate these robots in such dynamic environments, which requires continuous decision-making and environment-attribute update in real-time. An autonomous robot guide is well suitable in places such as museums, libraries, schools, hospital, etc. This paper addresses a scenario where a robot tracks and follows a human. A neural network is utilized to learn the skin and nonskin colors. The skin-color probability map is utilized for skin classification and morphology-based preprocessing. Heuristic rule is used for face-ratio analysis and Bayesian cost analysis for label classification. A face-detection module, based on a 2D color model in the and YUV color space, is selected over the traditional skin-color model in a 3D color space. A modified continuously adaptive mean shift tracking mechanism in a 1D hue, saturation, and value color space is developed and implemented onto the mobile robot. In addition to the visual cues, the tracking process considers 16 sonar scan and tactile sensor readings from the robot to generate a robust measure of the person's distance from the robot. The robot thus decides an appropriate action, namely, to follow the human subject and perform obstacle avoidance. The proposed approach is orientation invariant under varying lighting conditions and invariant to natural transformations such as translation, rotation, and scaling. Such a multimodal solution is effective for face detection and tracking.
Using the Canny edge detector for feature extraction and enhancement of remote sensing images (2002)

Edges are important features in an image since they represent significant local intensity changes. They provide important clues to separate regions within an object or to identify changes in illumination. Most remote sensing applications, such as image registration, image segmentation, region separation, object description, and recognition, use edge detection as a preprocessing stage for feature extraction. Real images, such as remote sensing images, can be corrupted with point noise. The real problem is how to enhance noisy remote sensing images and simultaneously extract the edges. Using the implemented Canny edge detector for feature extraction and as an enhancement tool for remote sensing images, the result was robust with a very high enhancement level.
An Approach to Design Highly Durable Piezoelectric Nanogenerator Based on Self‐Poled PVDF/AlO‐rGO Flexible Nanocomposite with High Power Density and Energy Conversion Efficiency (2016)

Till date, fabrication of piezoelectric nanogenerator (PNG) with highly durable, high power density, and high energy conversion efficiency is of great concern. Here a flexible, sensitive, cost effective hybrid piezoelectric nanogenerator (HPNG) developed by integrating flexible steel woven fabric electrodes into poly(vinylidene fluoride) (PVDF)/aluminum oxides decorated reduced graphene oxide (AlO‐rGO) nanocomposite film is reported where AlO‐rGO acts as nucleating agent for electroactive β‐phase formation. The HPNG exhibits reliable energy harvesting performance with high output, fast charging capability, and high durability compared with previously reported PVDF based PNGs. This HPNG is capable for harvesting energy from a variety and easy accessible biomechanical and mechanical energy sources such as, body movements (e.g., hand folding, jogging, heel pressing, and foot striking, etc.) and machine vibration. The HPNG exhibits high output power density and energy conversion efficiency, facilitating direct light on different color of several commercial light‐emitting diodes instantly and powers up many portable electronic devices like wrist watch, calculator, speaker, and mobile liquid crystal display (LCD) screen through capacitor charging. More importantly, HPNG retains its performance after long compression cycles (≈158 400), demonstrating great promise as a piezoelectric energy harvester toward practical applications in harvesting biomechanical and mechanical energy for self‐powered systems.
Combining two media access protocols to support integrated traffic on high data rate networks (2002)

The paper describes the operation and performance of an integrated traffic network using separate media access protocols to support different traffic types on a single unidirectional ring or bus. One protocol, based upon local carrier sensing (CSMA/RN) provides access for asynchronous traffic; the other, a 'train like' protocol called the circulating reservations packets (CRPs), provides access for synchronous voice and video traffic. Other media access protocols like slotted ring or QPSX are equally applicable for use as the asynchronous protocol.< <ETX xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">></ETX>
Serotonin concentration in offspring of parents suffering from premature coronary arterial disease. (1992)

Thirty-one 3 to 14 years old offspring of parents who had an acute myocardial infarction before age of 45 and 42 healthy children without any family history of cardiovascular disease were investigated. A significant increase in plasma free serotonin concentration was seen in endangered children. From these results it may be supposed that vascular endothelium is dysfunctional in offspring of parents suffering from premature coronary arterial disease.
DNA-Induced Transformation in <i>Drosophila:</i> Genetic Analysis of Transformed Stocks (1971)

The exosome model of transformation in Drosophila melanogaster proposes that DNA fragments enter the cells of treated individuals and become firmly associated with their homologous chromosome segments, but are never integrated into the linear structure of the chromosome. This paper reports results that validate two central predictions of the model: (a) the introduced genetic information usually maps precisely at the site of the target locus, and (b) the original chromosomal information is still present at that site.
Direct Synthesis of Porous Multilayer Graphene Materials Using Thermal Plasma at Low Pressure (2015)

Porous multilayer graphenes have been synthesized by decomposition of hydrocarbons in a thermal plasma jet. Products of synthesis were characterized by electron microscopy, thermogravimetry, Raman spectroscopy, and X‐ray diffraction. Possibility of producing a wide range of graphene materials with different morphology and structure has been shown. Influence of the experimental conditions on mesopores structure of the synthesis products has been investigated using the method of “limited evaporation.”
Practical Design Techniques for FR4 Material-Based Microwave Hairpin Filters (2001)

This paper presents practical design techniques for building hairpin fillers using FR4 laminates. This type of microwave microstrip filter is among the most popular low microwave frequency filters because of its compact size and ease of manufacturing. However, building the hairpin filter using FR4 laminates is very difficult to do because of the relatively poor performance of the laminate at the microwave region. The motivation to use FR4 in the low microwave frequencies is its availability and inexpensive manufacturing process. Methods and techniques were to address these problems of the FR4.
Class E low dvD/dt rectifier (1989)

The paper presents a new Class E low dvD/dt rectifier, its analysis and experimental results. The rectifier circuit contains a capacitor connected in parallel with a rectifying diode. The capacitor sets the conduction angle of the diode current, and the output-filter capacitor independently sets the AC ripple on the DC output voltage. The diode-junction capacitance is included in the parallel capacitance and threrefore does not adversely affect circuit operation at high operating frequencies. The diode turns on and off at low dvD/dt, yielding low switching losses and low switching noise. Moreover, the absolute value of diD/dt at turn-off is limited by an external circuit, significantly reducing the reverse-recovery effect. For these reasons, the rectifier is especially suitable for high-frequency operation. Basic parameters of the circuit are derived, using time-domain analysis. The experimental and theoretical results were in good agreement.
Therapeutic Lymphangiogenesis With Implantation of Adipose‐Derived Regenerative Cells (2012)

Implantation of autologous ADRCs could be a useful treatment option for patients with severe lymphedema via mediation of lymphangiogenesis. (J Am Heart Assoc. 2012;1:e000877 doi: 10.1161/JAHA.112.000877.).
A Study on Mediation Effect of Support System in Job Stress and Coping Behavior of Social Workers (2019)

Stress affects the type of adaptation required for each case and the type of social support is also different. In order for social support to have a buffer effect on stress, we want to understand how to measure social support and support according to specific stress situations. Therefore, this study examines coping behaviors of community service workers exposed to these job stresses and examines the effect of support system (family support, peer support, superior support) on coping behavior. The purpose of this study is to investigate the effects of stress, coping resources and coping behaviors of community service workers. In this study, self - report method was used to investigate the questionnaire using structured questionnaires. In this study, the statistical program was used for data analysis and hierarchical regression analysis.
Unsupervised Models for Named Entity Classification (1999)

This paper discusses the use of unlabeled examples for the problem of named entity classification. A large number of rules is needed for coverage of the domain, suggesting that a fairly large number of labeled examples should be required to train a classifier. However, we show that the use of unlabeled data can reduce the requirements for supervision to just 7 simple &quot;seed&quot; rules. The approach gains leverage from natural redundancy in the data: for many named-entity instances both the spelling of the name and the context in which it appears are sufficient to determine its type. We present two algorithms. The first method uses a similar algorithm to that of (Yarowsky 95), with modifications motivated by (Blum and Mitchell 98). The second algorithm extends ideas from boosting algorithms, designed for supervised learning tasks, to the framework suggested by (Blum and Mitchell 98). 1 Introduction Many statistical or machine-learning approaches for natural language problems require a rel...
Temperature Sensitive Liposomes of Plumbagin: Characterization and In Vivo Evaluation in Mice Bearing Melanoma B16F1 (2002)

The effectiveness of the combination of thermosensitive liposomes of plumbagin and hyperthermia is described. Small-sized, thermosensitive liposomes were prepared by thin film hydration and subsequent sonication. The liposomes were characterized for size, phase transition temperature, in vitro drug release and stability. The results of particle size analysis indicated that almost 90% of the vesicles were below 0.19 microm size. The phase transition temperature of the liposomes as determined by differential scanning calorimetry was found to be 41.32 degrees C. The results of in vitro release studies in phosphate buffered saline + mouse plasma indicated that maximum drug release (51.25%) occurred at 42 degrees C compared to the less than 9% release at 37 degrees C. Better stability profile was observed when the plumbagin liposomes were stored at 4 degrees C. When combined with localised hyperthermia (43 degrees C, 30 min or 1 h), liposomal plumbagin administered intravenously to C57BL/6J mice bearing melanoma exhibited better anticancer activity as compared to animals treated with an equivalent dose of free plumbagin with or without hyperthermia, which was evident by enhanced volume doubling time and growth delay.
MO‐EE‐A2‐02: Monte Carlo Simulation and Development of a Multileaf Collimator for Proton Therapy (2009)

Purpose: To develop a multileaf collimator (MLC) for proton therapy. Method and Materials: We constructed a model of the IBA proton beam delivery nozzle at our facility with the Geant4 (v9.1) toolkit and, in partnership with Varian Medical Systems, employed it to optimize the shielding design for a multileaf collimator system. Simulation studies were carried out with the highest‐energy, maximally‐modulated spread‐out‐Bragg‐peak settings and for the largest possible field size in both double scattering and uniform scanning modes. This led us iteratively to a solution that maintained proton and neutron leakage doses at an acceptable level. Results: Our final design comprised 50 leaf pairs made from a tungsten‐based alloy. Each leaf is roughly 9 cm high and 11 cm long—enabling 1.5 cm of overtravel—and projects to approximately 0.5 cm at isocenter; one half‐height 450 μm side‐step and two one‐third‐height 300 μm end‐steps are built in. Maximum achievable field sizes are 16×16 cm 2 and 18×25 cm 2 respectively in double scattering and uniform scanning modes. Conclusion: A MLC system has been designed for use in double scattered and uniform scanned proton therapy without significantly changing the standard IBA nozzle design or the mechanical and electronic systems currently used by Varian photon MLCs. Our simulations predict that the system will provide shielding at least as good as that provided by a conventional brass aperture. A prototype has been manufactured and is presently being installed on the nozzle in one of our gantry rooms. We expect to make measurements of leakage, penumbra and activation in the coming weeks and to validate our Monte Carlo simulations.

Everett R. Smith (1964)

O MOST marketing executives and teachers Everett R. Smith, Director of Marketing and Research of Macfadden-Bartell Corporation, is a familiar figure as an active member and past president of this association. A Connecticut Yankee and direct descendant of Roger Williams (founder of Rhode Island), Everett R. Smith was born and grew up in New Haven. He received his B.A. cum laude from Yale in 1907 and was a top-ranking member of Phi Beta Kappa. After graduation he started in the newspaper field, soon became city editor, and then moved to the position of business and advertising manager of the New Haven Journal-Courier. Everett Smith's interests soon changed, and he turned to other fields of business. He became a salesman of farm equipment. He joined an advertising agency, but in 1926 became an advertising and sales executive of one of its clients,ERET the Fuller Brush Company. As Advertising Manager of the Fuller Brush Company, he planned their first massive advertising campaign. This effort was notable at that time for its size of operations; and his carefully planned campaigns became major factors which resulted in the rapid development and expansion of Fuller Brush
PROTOCOL FOR DRIVERLESS USB HID RELIABLE DATA TRANSFER (2016)

The modern PC, instead of coming equipped with outdated serial and parallel ports, has USB ports. Their well-known advantages include high communication speed and hot swapping. However, in many cases, use of USB ports requires installation of software drivers on the target PC, where installation is not always possible because of security requirements. One possible solution is the driverless USB Human Interface Device (HID) protocol. The goal of this contribution is to evaluate the feasibility and reliability of the expandable and reusable driverless USB HID platform on PC and embedded PIC devices supporting USB HID data transfer. Two data transfer protocols were implemented, evaluated, and compared. The “master sends request – slave responds with message” protocol was found more reliable than the “blocking loop” protocol.

A 16-Mb 400-MHz loadless CMOS four-transistor SRAM macro (2000)

We have used a 5-metal 0.18-/spl mu/m CMOS logic process to develop a 16-Mb 400-MHz loadless CMOS four-transistor SRAM macro. The macro contains: (1) end-point dual-pulse drivers for accurate timing control; (2) a wordline-voltage-level compensation circuit for stable data retention; and (3) an all-adjoining twisted bitline scheme for reduced bitline coupling capacitance. The macro is capable of 400-MHz high-speed access at 1.8-V supply voltage and is 66% the size of a conventional six-transistor SRAM macro. We have also developed a higher-performance 500-MHz loadless four-transistor SRAM macro in a CMOS process using 0.13-/spl mu/m gate length.
Vaccine potential of an attenuated Pasteurella multocida that expresses only the N-terminal truncated fragment of P. multocida toxin in pigs. (2012)

Previously we described the development of an attenuated Pasteurella multocida mutant that expresses only the N-terminal truncated fragment of P. multocida toxin (N-PMT) and its protective effects in a mouse model. This paper details our evaluation of the vaccine potential of this mutant strain in pigs. Pigs vaccinated with the mutant showed significantly higher rates of antibody induction and lower nasal conchal (turbinate) scores for atrophic rhinitis than controls, which suggests that this mutant strain may be a good candidate for a live attenuated vaccine.
논문 : 핵분열 생성핵종 Cs -137 감마선의 측정에 의한 PWR 사용후 핵연료 연소도 평가 (1992)

사용후 가압경수로 핵연료봉속에 들어 있는 핵분열 생성핵종의 하나인 Cs-137 감마선의 상대적 세기를 핵연료봉의 길이방향 및 단면방향으로 측정(스캐닝)하고 이곳에서 시료를 취하여 화학분석법인 Nd-148 정량법으로 연소도를 구한 후 Cs-137 검출세기와 연소도간의 관계식을 유도하였는데 이들은 연소도 영역 10∼35 GWD/MTU에서 일차 선형적으로 비례하고 있음이 확인되었다. 아울러, 임의의 사용후 가압 경수로 핵연료를 대상으로 한 검정시험에서 검출된 Cs-137 감마선의 세기를 이 관계식에 대입하여 계산한 연소도와 Nd-148 정량법으로 산출한 값을 비교하였다.
그 결과, 양자간에는 잘 일치하고 있음을 보여주었다. 이로서 유도된 관계식을 이용하여 Cs-137 감마선세기의 분포로 부터 연소도를 추정하는 것이 가능하게 되었다.
Identification of One of the Major Viruses Infecting Garlic Plants, Garlic Virus X (1997)

A partial cDNA clone for garlic virus X (GVX) was isolated. GVX was identified immunologically with an antibody raised against the recombinant coat protein (CP) and demonstrated to be one of the major viruses infecting garlic plants showing mosaic or streak symptoms. GVX belongs to an unassigned group of ShVX and GarV-type viruses rather than to carlaviruses or potexviruses. The recombinant CP of GVX was purified by Ni(2+)-NTA affinity chromatography. Anti-GVX CP antibody was raised against the purified recombinant CP. GVX particle is flexuous, rod-shaped, and about 750 nm long as determined by immunoelectron microscopy. The extent of infection by GVX of garlic plants was analyzed by Northern or immunoblot analyses of individual garlic plants cultivated in different regions. These results showed that almost all of the garlic plants tested from 40 different regions including America, China, Japan, and Korea are infected with GVX.
Compression of Chinese text files using a multiple four-bit coding scheme (1992)

This paper reports on the results of the study of a two-pass reversible data compression scheme. The restricted variable length coding method using multiples of 4-bit code values is simple in concept and easy to implement. The compression results and the compression/decompression times regarding four large Chinese text files are superior to those using character-based two-pass Huffman coding and adaptive Huffman coding methods. The compression results are comparable with what the LZW method achieves, and the compression/decompression process it slightly faster.< <ETX xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">></ETX>
Poled polymer films for nonlinear optics (1989)

Five focus group discussions were conducted with 28 (fourth-year) medical students from the Chinese University of Hong Kong (CUHK) to explore attitudes to Traditional Chinese Medicine (TCM) and its impact on the future of medical training. Most students perceived that TCM was a good alternative for certain health problems but lack of scientific evidence and the absence of regulation were major barriers. Students were concerned about the limitations of TCM, but identified their need to understand TCM to effectively communicate with their patients. Paralleled with the experience in the United Kingdom and other countries, if traditional and conventional doctors are to work effectively side by side, current medical education and health service arrangements need to change.
A comparative study of the biologic and immunologic response to medical devices derived from dermal collagen (1986)

We examined collagen materials for soft tissue augmentation [Zyderm Collagen Implant (ZCI), glutaraldehyde cross-linked (GAX) collagen, and Koken Atelocollagen (Atelocollagen)]; hemostatic collagens [Gelfoam Gelatin Powder (Gelfoam), Avitene Microfibrillar Collagen Hemostat (Avitene), and Collastat Collagen Hemostat (Collastat)]; and reconstituted, intact fibrillar collagen from bovine skin in a subcutaneous guinea pig model. After 11, 25, and 39 days in situ, explants from animals injected with GAX collagen demonstrated greater wet-weight persistence than all other materials. Conversely, at all time points, the explants of Atelocollagen were the least persistent. Following 25 days in vivo, explants were examined using differential scanning calorimetry; ZCI and Atelocollagen displayed thermal transition temperatures of 58 degrees C. Avitene and Gelfoam explants displayed transition points of 30 degrees C and 32 degrees C, indicating denatured or cleaved collagen. By contrast, GAX collagen explants had a high (68 degrees C) transition temperature, reflecting its cross-linking. With respect to immunogenicity, day 39 sera from ZCI treated animals showed significantly lower titers in the ELISA to their respective implant collagen than all other groups examined, while antibody activity in the GAX collagen, Gelfoam, Atelocollagen, and intact collagen groups were not significantly different. Collastat elicited antibodies with a greater affinity than observed in these previous groups. Sera from Avitene treated animals demonstrated the highest antibody levels and were the only sera which reacted with bovine serum albumin. Thus, Avitene was the most immunogenic of the collagen materials examined, while GAX collagen demonstrated the greatest persistence and minimal immunogenicity, and ZCI was the least immunogenic.
