Data rate enhancement of optical camera communications by compensating inter-frame gaps (2017)

Optical camera communications (OCC) is a convenient way of transmitting data between LED lamps and image sensors that are included in most smart devices. Although many schemes have been suggested to increase the data rate of the OCC system, it is still much lower than that of the photodiode-based LiFi system. One major reason of this low data rate is attributed to the inter-frame gap (IFG) of image sensor system, that is, the time gap between consecutive image frames. In this paper, we propose a way to compensate for this IFG efficiently by an interleaved Hamming coding scheme. The proposed scheme is implemented and the performance is measured.
Inhibition of Metastases by Anticoagulants (1999)

Metastasis involves several distinct steps, including one in which the tumor cell, after entry into the bloodstream, comes to rest in a capillary located at the distant site where a metastatic tumor will ultimately form. Components of the blood-clotting pathway may contribute to metastasis by trapping cells in capillaries or by facilitating adherence of cells to capillary walls. Conceivably, anticoagulants could interfere with this step in the metastatic process. In this review, we have summarized current knowledge on the interaction of malignant cells, clotting factors, and anticoagulants. We used computerized (MEDLINE) and manual searches to identify studies done in humans, in animals, and in in vitro systems that were published in English between 1952 and 1998. We found many reports that the formation of metastatic tumors could be inhibited by heparin, a vitamin K antagonist (warfarin), and inhibitors of platelet aggregation (prostacyclin and dipyridamole). Despite these encouraging preliminary results and a compelling biochemical rationale, only limited information exists on the clinical use of anticoagulants for the prevention or treatment of metastatic cancer because there have been so few controlled and prospectively randomized studies on this topic. In view of the preliminary results, anticoagulants may hold promise for the prevention and treatment of metastases. We believe that larger controlled investigations are strongly warranted to evaluate the clinical potential of anticoagulants for the prevention and treatment of metastases in humans.
Development of puncture resistance tire tube; Nirinsha no taipankusei kojo cube no kaihatsu (1997)

A new tire tube with a puncture resistance function was developed. The tube is a two-chamber structure having an air chamber and a liquid chamber, and the liquid chamber at the crown-side half of the tube is filled with an anti-puncture sealant during a manufacturing process. In a market test, it was confirmed that the number of puncture cases were reduced by 90 % in comparison with conventional tire tubes by using the newly developed tube. This paper describes the structure of the tube and the characteristics of the tube rubber, and the manufacturing process and durability of the tube. 3 refs., 17 figs.
Current Concepts of Inguinal Hernia Repair (2018)

With more than 20 million patients annually, inguinal hernia repair is one of the most often performed surgical procedures worldwide. The lifetime risk to develop an inguinal hernia is 27-43% for men and 3-6% for women. In spite of all advances, 11% of all patients suffer from a recurrence and 10-12% from chronic pain following primary inguinal hernia repair. By developing evidence-based guidelines and recommendations, the international hernia societies aim to improve the outcome of inguinal hernia repair due to standardization of care. From a total of more than 100 different repair techniques for inguinal and femoral hernias, classified as tissue repair, open mesh repair, and laparo-endoscopic mesh repair, the new International Guidelines of the Hernia-Surge Group only recommend the totally extraperitoneal patch plasty (TEP), transabdominal preperitoneal patch plasty (TAPP), and Lichtenstein techniques. Since a generally accepted technique suitable for all inguinal hernias does not exist, surgeons should provide both an anterior open (Lichtenstein) and a posterior laparo-endoscopic (TEP or TAPP) approach option. The guidelines strongly recommend that surgeons tailor the treatment of inguinal hernias based on expertise, local/national resources, and patient- and hernia-related factors. A tailored approach in inguinal hernia repair should pay heed to the patient- and hernia-related factors, unilateral hernia in men and women, bilateral hernia, recurrent hernia, scrotal hernia, previous pelvic and lower abdominal surgery, severe cardiac or pulmonary comorbidities, and incarcerated hernia.
Rotation-invariant digital pattern recognition using circular harmonic expansion (1982)

A new method has been developed for rotation-invariant pattern recognition. One component of the circular harmonic expansion of the target is used in the preparation of the reference. Correlations between the input and reference objects are accomplished by FFT and multiplication in the frequency domain. In an experience with targets from an image with 192 x 192 pixels, target orientations were detected with an accuracy of approximately 0.1 degrees . This method is also suitable for optical implementation.

Reaction of Some Schiff Base Complexes of Iron(III) with Nitrogen and Sulfur Donor Anions (2000)

Abstract Reactions of some Schiff bases with Fe(III) salts in the presence of nitrogen or sulfur donor anions have been investigated. The Schiff bases are derived from the reaction of salicylaldehyde, substituted salicyaldehyde or 2-hydroxy-1 -naphthaldehyde with 8-aminoquinoline, substituted aniline, ethylenediamine or o-phenylenediamine. The obtained Schiff bases act either as tridentate or tetradentate dibasic ligands. Tentative structures have been assigned on the basis of elemental analyses, conductivity, spectral and magnetic data. Most of the obtained complexes are proposed to be hexa-coordinate but some might be penta-coordinate. The added anions (thiocynate, 8-aminoquinolate, pyrrolidinedithiocarbamate or piperazinedi(dithiocarbamate) are bonded to iron, in addition to the Schiff base, producing mononuclear complexes or act as bridging groups producing dinuclear or polynuclear complexes.
Effect of Quizalofop-Ethyl on Glutathione-S-Transferases and Carboxylesterase Activity of Soybean and Corn Plants (1997)

Biochemical characteristics and activities of glutathione-S-transferases(GSTs) and carboxylesterase extracted from soybean and corn plants treated with quizalofop-ethyl were investigated. Km value and Vmax of GSTs extracted from soybean and corn plants were nmole/mg/min, 50, 20 nmole/mg/min, respectively. Optimum pH of carboxylesterase from soybean and corn was 7.0. Km value and Vmax of carboxylesterase extracted from soybean and corn plants were , nmole/mg/min, 33, 10 nmole/mg/min, respectively. GSTs and carboxylesterase activity were reduced by quizalofop-ethyl. GSTs and carboxylesterse activity of corn was more reduced than that of soybean. When soybean and corn were treated by 80 ppm of quizalofopethyl. Soybean recovered after 10 days elapsing, but corn withered after 3days elapsing.
Mobility Support for Nimrod : Challenges and Solution Approaches (1997)

We discuss the issue of mobility in Nimrod. While a mobility solution is not part of the Nimrod architecture, Nimrod does require that the solution have certain characteristics. We identify the requirements that Nimrod has of any solution for mobility support. We also classify and compare existing approaches for supporting mobility within an internetwork and discuss their advantages and disadvantages. Finally, as an example, we outline the mechanisms to support mobility in Nimrod using the scheme currently being developed within the IETF - namely, the Mobile-IP protocol.
Scenario Analysis of Web Service Composition based on Multi-Criteria Mathematical Goal Programming (2011)

This paper addresses the web service composition problem considering multi-criteria regarding quality of services (QoS). Three different scenarios of multi-criteria mathematical programming models are explored under the framework of network based analysis in web service composition. This work takes care of the issues pertaining to inputs and outputs matching of web services and Quality-of-Service (QoS) at the same time. The multi-criteria programming models are explored to select the desirable service composition in a variety of categories in accordance with customers' preferences in three different scenarios: (1) Optimal, (2) Compromised optimal, and (3) Acceptable. This set of multi-criteria models have both advantages and disadvantages comparing with each other, and can be used as different solvers in the network based service composition framework. The proposed regular multi-criteria programming (MCP) models are used in Scenario (1): Optimal. The proposed multi-criteria goal programming for optimal composition (MCGPO) and multi-criteria goal programming for non-optimal solution (MCGPN) models are designed for Scenarios (2): Compromised optimal and (3) Acceptable respectively. And they can find a compromised composition based on the trade-off of customer's preference on the QoS goals in case that the optimal composition satisfying both functional and QoS constraints does not exist in the network.

The urinary excretion of N<sup>τ</sup>-methyl histidine in sheep: an invalid index of muscle protein breakdown (1980)

1. The validity of the urinary excretion of N tau-methyl histidine (N tau-MH) in sheep as a measure of the breakdown of muscle protein in vivo was assessed from the urinary recovery of radioactivity following the intravenous administration of N tau-[14CH3]methyl histidine. 2. Recoveries of radioactivity in urine from animals of 4 weeks to 7 years of age were incomplete in 7 d but progressively increased with the age of the animal, becoming almost quantitative (90%) in older animals after recovery for 3 weeks. 3. The incomplete urinary recoveries were not due to partial excretion of N tau-MH in faeces or its oxidation and elimination in expired gases but were related to the presence in muscle of a pool of non-protein-bound N tau-MH which was several times larger than the expected daily urinary excretion. 4. This pool in newly accreted muscle tissue was maintained by retention of some of the N tau-MH released by breakdown of muscle protein. Hence, only a proportion of the N tau-MH released from protein breakdown was available for excretion. This proportion increased with the age of the animal and was probably the main determinant of the improved recoveries of radioactivity obtained in urine from older animals. 5. The non-protein-bound N tau-MH in muscle consisted of free N tau-MH and a dipeptide containing N tau-MH, the latter comprising on average approximately 82% of the total non-protein-bound N tau-MH in muscle. This proportion did not change appreciably with the age of the animal. 6. The dipeptide appeared to be synthesized in muscle from free N tau-MH and was not a terminal product of protein breakdown. 7. The results show that urinary excretion of N tau-MH is not a reliable index of muscle protein breakdown in sheep.

Easy to fill sloped vias for interconnects applications improved control of silicon tapered etch profile (2009)

The first part of this paper aims to illustrate the possibility to control the shape of the top of a tapered silicon via using an SF <sub xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">6</sub> /O <sub xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">2</sub> chemistry with high etch rate (~14 mum/min). This etch has been performed using an ICP machine, customized for this type of etch. Usually, for such a tapered etch process, a local bowed sidewall profile undercuts the mask at the top of the via. By removing this local bow, the aim is to facilitate the use of such tapered profile for through silicon via (TSV) interconnects, as used for CMOS applications or MEMS packaging in mass production today. The second part of this paper relates to the study of some trends obtained by varying process parameters such as pressure or platen power.

Cloud Computing Applications and theirTesting Methodology (2014)

Cloud computing has opened up new opportunities for testing departments. New technology and social connectivity trends are creating a perfect storm of opportunity, enabling cloud to transform internal operations, customer relationships and industry value chains. To ensure high quality of cloud applications under development, developer must perform testing to examine the quality and accuracy whatever they design. Business users are drawn to cloud’s simplified, self-service experience and new service capabilities. In this research paper, we address a testing environmental architecture with valuable key benefits, to perform execution of test cases and used testing methodologies to enhance quality of cloud applications.
Water chemisorption and reconstruction of the MgO surface (1995)

The observed reactivity of MgO with water is in apparent conflict with theoretical calculations which show that molecular dissociation does not occur on a perfect (001) surface. We have performed ab initio total-energy calculations which show that a chemisorption reaction involving a reconstruction to form a (111) hydroxyl surface is strongly preferred with \ensuremath{\Delta}E=-90.2 kJ ${\mathrm{mol}}^{\mathrm{\ensuremath{-}}1}$. We conclude that protonation stabilizes the otherwise unstable (111) surface and that this, not the bare (001), is the most stable surface of MgO under ambient conditions.
Dissection of the Mammalian Midbody Proteome Reveals Conserved Cytokinesis Mechanisms (2004)

Cytokinesis is the essential process that partitions cellular contents into daughter cells. To identify and characterize cytokinesis proteins rapidly, we used a functional proteomic and comparative genomic strategy. Midbodies were isolated from mammalian cells, proteins were identified by multidimensional protein identification technology (MudPIT), and protein function was assessed in Caenorhabditis elegans. Of 172 homologs disrupted by RNA interference, 58% displayed defects in cleavage furrow formation or completion, or germline cytokinesis. Functional dissection of the midbody demonstrated the importance of lipid rafts and vesicle trafficking pathways in cytokinesis, and the utilization of common membrane cytoskeletal components in diverse morphogenetic events in the cleavage furrow, the germline, and neurons.
The Synthesis of Some Food Dyes for Natural and Synthetic Fibres (2012)

The food dyes with carotene are used in the manufacture of bread and pastry, butter, margarine, jellies, etc (1). The pigments from plants are also used as dyes (2), alongside with pigments which were extracted from fruits or vegetables (3). The fruit juice is turned into a starch paste which is more soluble at low temperatures. Most of the synthesized food dyes are monoazo dyes. They result from the diazotization of amines which is followed by coupling with various coupling components. The water soluble dyes were analyzed in various ways. Their chemical properties were determined and, as a result, they were classified into basic, neutral, sulphonated and non-sulphonated. The following food dyes were obtained: 12 Red (4), 10 Red (5), Blue 1 (6), Yellow 8 (7), Orange 1 (8). New methods were used. The chemical formulae of these dyes are the following: Experimental part The solutions of the dyes have a concentration of 1-4% in water. The dye sample to be analyzed is spotted on the chromatographic plate. It is left for 30 min in the tub with the mobile phases to migrate on a distance of 8.5 cm from the layer margin. The dye spot is visualized in the daylight. Solvents: normal butanol, ethyl alcohol, water, normal propanol, sodium bicarbonate.
High speed locomotion for a quadrupedal microrobot (2014)

Research over the past several decades has elucidated some of the mechanisms behind high speed, highly efficient, and robust locomotion in insects such as cockroaches. Roboticists have used this information to create biologically inspired machines capable of running, jumping, and climbing robustly over a variety of terrains. To date, little work has been done to develop an at-scale insect-inspired robot capable of similar feats due to challenges in fabrication, actuation, and electronics integration for a centimeter-scale device. This paper addresses these challenges through the design, fabrication, and control of a 1.27 g walking robot, the Harvard Ambulatory MicroRobot (HAMR). The current design is manufactured using a method inspired by pop-up books that enables fast and repeatable assembly of the miniature walking robot. Methods to drive HAMR at low and high speeds are presented, resulting in speeds up to 0.44 m/s (10.1 body lengths per second) and the ability to maneuver and control the robot along desired trajectories.
An antenna for medical implant communications system (2007)

Tissue implanted devices are of great interest for wireless medical applications due to the promise of different clinical usages in order to promote a patient’s independence. A key component of wireless implanted device is an antenna, and there are several issues to consider while designing an in-body antenna, including power consumption, size, frequency, biocompatibility and the unique RF transmission challenges posed by the human body. This paper mainly deals with an implantable antenna designing for the frequency range of 402- 405 MHz.
The Detection of Ethylene in the Internal Atmosphere of Bulbs1 (1970)

Abstract Ethylene was detected in the internal atmosphere of 5 bulb species. Some, if not all, of the determined ethylene concn are of physiological significance. Experiments using methyl l-(butylcarbamoyl)-2-benzimi-dazole carbamate, a protective fungicide, indicate that fungi normally associated with tulip bulbs are at least partially responsible for the gas.
Rate-distortion optimized compression and view-dependent transmission of 3-D normal meshes (2005)

A unified approach to rate-distortion (R-D) optimized compression and view-dependent transmission of three-dimensional (3-D) normal meshes is investigated in this work. A normal mesh is partitioned into several segments, which are then encoded independently. The bitstream of each segment is truncated optimally using a geometry distortion model based on the subdivision hierarchy. It is shown that the proposed compression algorithm yields a higher coding gain than the conventional algorithm. Moreover, to facilitate interactive transmission of 3-D data according to a client's viewing position, the server can allocate an adaptive bitrate to each segment based on its visibility priority. Simulation results demonstrate that the view-dependent transmission technique can reduce the bandwidth requirement considerably, while maintaining a good visual quality.
Effect of Membrane Pore Size on the Performance of a Membrane Reactor for Biodiesel Production (2006)

Biodiesel was produced from canola oil and methanol in a novel membrane reactor. The membrane in the reactor served to separate the unreacted emulsified oil from the product stream, producing high-purity fatty acid methyl ester (FAME). The effects of the pore size of the membrane used in the semicontinuous reactor and the initial methanol/canola oil loading were studied. Four carbon membranes having different pore sizes of 0.05, 0.2, 0.5, and 1.4 μm were tested, with four different initial methanol volume fractions (φ1) of 0.29, 0.38, 0.47, and 0.64. It was found that all four membranes retained canola oil in the reactor. Permeate was observed at the 0.38, 0.47, and 0.64 initial methanol volume fractions, whereas it was not observed at φ1= 0.29. The initial oil loadings represent methanol/oil mole ratios of 11:1, 16:1, 23:1, and 46:1. For all runs, no triglycerides were found in the permeate. The permeate dephased upon cooling to room temperature. Glycerol was not detected in the FAME-rich phase. This opens the possibility of reaching methanol/oil mole ratios of 6:1 with a single recycling step.
Simple relationship between differential mode delay in optical fibres and the deviation from optimum profile (1978)

A very simple formula is given for determining the deviation of a given refractive-index profile from optimum after the differential mode delay has been measured.
Microwave frequency memory using GaAs transferred-electron devices (1974)

An investigation was made of the behavior of a transferred-electron device (TED) in a multimode resonant microwave cavity, to design such cavity and TED to optimize the number of allowed memory states in a given overall bandwidth, and to initiate a theoretical and experimental study leading toward development of a compact multimode cavity structure suitable for ECM frequency memory applications above 8 GHz. The study includes but is not limited to microstrip resonators. TE memorizers were designed and constructed using coaxial, waveguide, and alumina microstrip circuits. Operation between 10.34 and 12.46 GHz with 17 states spaced about 132 MHz apart was demonstrated with a 2-in. x 2-in. x 0.025-in. alumina circuit. A 5-foot waveguide circuit has operated between 9.75 and 10.82 GHz with 16 states spaced about 71 MHz apart, as was a 7-foot coaxial circuit between 11.0 and 11.77 GHz with 18 states spaced about 45 MHz apart. Switching between states has been achieved with pulsed rf input signals as short as 0.1 microsec.
A neural network alternative to non-negative audio models (2017)

We present a neural network that can act as an equivalent to a Non-Negative Matrix Factorization (NMF), and further show how it can be used to perform supervised source separation. Due to the extensibility of this approach we show how we can achieve better source separation performance as compared to NMF-based methods, and propose a variety of derivative architectures that can be used for further improvements.
