An optimal design method for multi-section superconducting magnets using modified simulated annealing (1994)

It is important for the efficiency of superconductor utilization to minimize winding volume of superconducting magnets. In order to reduce the winding volume, high-field superconducting magnets are usually subdivided into a number of coaxial coils. In this paper, we propose an optimal design method using a modified Simulated Annealing technique, which is newly developed, to realize the minimum winding volume design for multi-section superconducting magnets. The details of the algorithm and several examples of its application to three-section superconducting magnets are shown.< <ETX xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">></ETX>
Inaudible sound as a covert channel in mobile devices (2014)

Mobile devices can be protected by a variety of information flow control systems. These systems can prevent Trojans from leaking secrets over network connections. As mobile devices become more secure, attackers will begin to use unconventional methods for exfiltrating data.

We propose two sound-based covert channels, ultrasonic and isolated sound. Speakers on mobile devices can produce frequencies too high for most humans to hear. This ultrasonic sound can be received by a microphone on the same device or on another device. We implemented an ultrasonic modem for Android and found that it could send signals up to 100 feet away. We also determined that this attack is practical with the transmitter inside of a pocket. Android devices with vibrators can produce short vibrations which create isolated sound. These vibrations can be detected by the accelerometer, but they are not loud enough for humans to hear. If performed while the user is not holding the device, the vibrations will not be noticed.

Both covert channels can stealthily bypass many information flow control mechanisms. We propose several simple solutions to these vulnerabilities. In order to guarantee information flow control, sound-based channels must be regulated.
Multichannel active sound control using adaptive filtering (2003)

The active control of harmonic sound using multiple secondary sources and multiple error microphones is formulated in an adaptive digital filtering framework. A stochastic gradient algorithm is presented to minimize the sum of the squares of the error microphone outputs by adapting the coefficients of an array of FIR (finite-impulse response) filters driving the secondary sources. The properties and implementation of the algorithm are discussed and some results are presented which demonstrate that the noise at the engine firing frequency inside an automobile can be reduced by 10-15 dB using a practical implementation of such an active sound control system, which had a response time of 0.1 s in this application.< <ETX xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">></ETX>
Measurement of cytosolic calcium: fluorescent calcium indicators. (1988)

The invention of intracellularly trappable fluorescent indicators of [Ca2+i] has provided an important new way to answer many key questions about the role of Ca2+ and of other messengers in cell activation. Perhaps equally important, the results of these investigations have thrown up many interesting new questions. The suitability of this, or any other method of measuring [Ca2+]i, naturally depends on the tissue, the experimenter, the facilities available and the particular question to be asked. For simply measuring [Ca2+]i, fura-2 and indo-1 are likely to be preferable to quin2, although right now more is known about quin2, its behaviour and its calibration in cells. Anecdotal evidence suggests that indo-1 may have advantages over fura-2 although many more people are presently using fura-2. For manipulating [Ca2+]i by deliberately adding Ca2+ buffering power, quin2 may have advantages and is certainly the tried and tested method. For epithelial cell work, where the relation of the cells to the rest of the tissue and their polarity are critical, suspensions and even monolayer measurements will seldom be adequate. Calcium microelectrodes or single-cell fluorescence techniques will surely be required and rewarding.
Turbo code concepts made easy, or how I learned to concatenate and reiterate (2002)

The goal of this paper is to describe the main ideas behind the new class of codes called turbo codes, whose performance in terms of bit-error-probability has been shown to be very close to the Shannon limit. The benefits of these concatenated codes are illustrated in the context of likelihood functions and a posteriori probabilities. Since the algorithms needed to implement the decoders have been well documented by others, they are only referenced here, but not described in detail. A numerical example, using a simple concatenated coding scheme, provides a vehicle for explaining how error performance can be improved when soft outputs from the decoders are used in an iterative decoding process.
Control of Abscisic Acid Catabolism and Abscisic Acid Homeostasis Is Important for Reproductive Stage Stress Tolerance in Cereals1     (2011)

Drought stress at the reproductive stage causes pollen sterility and grain loss in wheat (Triticum aestivum). Drought stress induces abscisic acid (ABA) biosynthesis genes in anthers and ABA accumulation in spikes of drought-sensitive wheat varieties. In contrast, drought-tolerant wheat accumulates lower ABA levels, which correlates with lower ABA biosynthesis and higher ABA catabolic gene expression (ABA 8'-hydroxylase). Wheat TaABA8'OH1 deletion lines accumulate higher spike ABA levels and are more drought sensitive. ABA treatment of the spike mimics the effect of drought, causing high levels of sterility. ABA treatment represses the anther cell wall invertase gene TaIVR1, and drought-tolerant lines appeared to be more sensitive to the effect of ABA. Drought-induced sterility shows similarity to cold-induced sterility in rice (Oryza sativa). In cold-stressed rice, the rate of ABA accumulation was similar in cold-sensitive and cold-tolerant lines during the first 8 h of cold treatment, but in the tolerant line, ABA catabolism reduced ABA levels between 8 and 16 h of cold treatment. The ABA biosynthesis gene encoding 9-cis-epoxycarotenoid dioxygenase in anthers is mainly expressed in parenchyma cells surrounding the vascular bundle of the anther. Transgenic rice lines expressing the wheat TaABA8'OH1 gene under the control of the OsG6B tapetum-specific promoter resulted in reduced anther ABA levels under cold conditions. The transgenic lines showed that anther sink strength (OsINV4) was maintained under cold conditions and that this correlated with improved cold stress tolerance. Our data indicate that ABA and ABA 8'-hydroxylase play an important role in controlling anther ABA homeostasis and reproductive stage abiotic stress tolerance in cereals.
Photochemical release of nitric oxide from a regenerable, sol-gel encapsulated Ru–salen–nitrosyl complex (2005)

Light activation leads to release of NO from a silicate sol-gel material SG-RuNO prepared from the ruthenium complex, [Ru(salen)(OH2)(NO)]+ (salen = N,N'-bis-(salicylidene)ethyl-enediaminato); after photochemical NO photolabilization, SG-RuNO can be regenerated from the spent material via the subsequent reaction with aqueous nitrite.
Design and Analysis of a Complete RFID System in the UHF Band Focused on the Backscattering Communication and Reader Architecture (2007)

A complete long range passive RFID system, compliant with the EPCGlobal UHF Class 1 Generation 2 standard, and focused on the backscattering tag-to-reader communication, is presented in this paper. Special emphasis has been placed on the reader, whose architecture is entirely designed and analyzed. Effects that degrade reader performance are studied. As a result, guidelines for a proper long range RFID reader design, with the main objective of maximizing the operating distance, are derived.
A Multicast-Avoiding Privacy Extension for the Avahi Zeroconf Daemon (2015)

In today’s local networks, a significant amount of traffic is caused by Multicast packets, such as Multicast DNS Service Discovery (mDNS-SD), a widespread technique used for configurationless service distribution and discovery. It suffers from two major problems inherent in multicast: privacy and network load. We present a privacy extension for the Avahi Zeroconf Daemon that tackles both problems while being very efficient.
Optofluidic biosensors: miniaturized multi-color flow cytometer and fluorescence-activated cell sorter (microFACS) (2011)

We report a portable, low-cost, and high-performance microfluidics based fluorescence-activated cell sorter (microFACS) system to isolate <i>E.coli</i>. cells in combination with a modified specific fluorescence labeling method called tyramide signal amplification-fluorescence <i>in situ</i> hybridization (TSA-FISH). One of the primary challenges in studying bacterial communities that elude cell culturing is to isolate of low abundance bacteria cell from heterogeneous microbial samples. The proposed TSA-FISH protocol is flow cytometry compatible and yields about 10-fold enhancement in fluorescence labeling intensity over widely used standard FISH staining methods. Teflon AF coated optofluidic waveguide and space-time coding with a matched filter algorithm enhance its detection sensitivity. The microFACS is also able to enrich TSA-FISH labeled <i>E.coli</i>. cells by a factor of 223 with an integrated piezoelectric actuator and realtime control electronics system. The microFACS in conjunction with the modified TSA-FISH technologies demonstrates a highly effective and low cost solution potentially for the genomic complexity of complex bacterial communities.

Relationships between energy balance and post-partum ovarian activity and fertility in first lactation dairy cows (1996)

Abstract Forty primiparous Holstein dairy cows were monitored from calving through 100 days in milk to evaluate the effect of energy balance in the early post-partum period on subsequent fertility. The post-partum interval to first ovulation (R 2 = 0·41; P < 0·005) was lengthened by greater negative energy balance, and reduced by greater body weight at parturition or decreased body-weight loss during the experimental period. Luteal activity (R 2 = 0·58; P < 0·0001), measured by plasma progesterone area under curve, was increased in the first cycle post partum by a shorter interval to first ovulation, improved energy balance during the 1st week of lactation and by decreased body-weight loss. Pregnancy status following first artificial insemination was related positively to the number of ovulations before insemination, improved energy balance during the 1st month post partum, fewer days to first ovulation and greater body weight at calving. These data suggest that energy balance and body weight are important in determining the post-partum interval to first ovulation and the subsequent fertility of first lactation dairy cotes.
Performance constraints generation for analog circuit layout (2002)

In this paper, a method for layout constraint generation of analog circuits is presented. The method comprises two phases: primitive recognition and constraint generation. A mixed analytical/knowledge-based technique is proposed. Complexity analysis shows the effectiveness of this method compared with simulation based methods.
Characterization of the entomocidal parasporal crystal of Bacillus thuringiensis (1977)

The parasporal crystalline protoxin of Bacillus thuringiensis contains a single glycoprotein subunit that has a molecular weight of approximately 1.2 X 10(5). The carbohydrate consists of glucose (3.8%) and mannose (1.8%). At alkaline pH, the proendotoxin is apparently solubilized and activated by an autolytic mechanism involving an inherent sulfhydryl protease that renders the protoxin insecticidal. Activation generates protons, degraded polypeptides, sulfhydryl group reactivity, proteolytic activity, and insect toxicity. Chemical modification of the sulfhydryl groups inhibits the proteolytic and insecticidal activities, suggesting that cysteine residues may be present in the active site of the protein.
Constitutive expression of the cloned phenol hydroxylase gene(s) from Alcaligenes eutrophus JMP134 and concomitant trichloroethylene oxidation (1996)

Given the demonstrated phenol-dependent trichloroethylene (TCE) degradation in Alcaligenes eutrophus JMP134 (A. R. Harker and Y. Kim, Appl. Environ. Microbiol. 56:1179-1181, 1990), this work represents a purposeful effort to create a constitutive degrader of TCE. Genes responsible for phenol hydroxylase activity were identified by Tn5 transposon mutagenesis. Mutants lacked both phenol hydroxylase and catechol 2,3-dioxygenase activities. Southern blot analysis of total DNA showed that all mutants contained a single copy of Tn5 inserted in the same 11.5-kb EcoRI fragment. Complementation with a cosmid-based gene bank constructed from A. eutrophus AEK101 allowed the isolation of three recombinant cosmids carrying a common 16.8-kb HindIII fragment. Deletion and subcloning analysis localized the genes involved in phenol hydroxylase and catechol 2,3-dioxygenase activities. Partial sequence analysis of regions within the cloned phenol hydroxylase-expressing fragment shows significant homology to the oxygenase and oxidoreductase subunits of toluene-3-monooxygenase from Pseudomonas pickettii. The Tn5-induced phl mutant, carrying a recombinant plasmid expressing the phenol hydroxylase activity, degrades TCE in the absence of induction. Complete removal of TCE (50 microM) within 24 h was observed in minimal medium containing only 0.05% ethanol as a carbon source. The bacterium removed 200 microM TCE to below detectable levels within 2 days under noninducing and nonselective conditions.

Interaction of Four Monoterpenes Contained in Essential Oils with Model Membranes:  Implications for Their Antibacterial Activity (2007)

The present article reports the antimicrobial efficacy of four monoterpenes (thymol, carvacrol, p-cymene, and gamma-terpinene) against the Gram-positive bacterium Staphylococcus aureus and the Gram-negative bacterium Escherichia coli. For a better understanding of their mechanism of action, the damage caused by these four monoterpenes on biomembranes was evaluated by monitoring the release, following exposure to the compounds under study, of the water-soluble fluorescent marker carboxyfluorescein (CF) from large unilamellar vesicles (LUVs) with different lipidic composition (phosphatidylcholine, PC, phosphatidylcholine/phosphatidylserine, PC/PS, 9:1; phosphatidylcholine/stearylamine, PC/SA, 9:1). Furthermore, the interaction of these terpenes with dimyristoylphosphatidylcholine multilamellar vesicles as model membranes was monitored by means of differential scanning calorimetry (DSC) technique. Finally, the results were related also with the relative lipophilicity and water solubility of the compounds examined. We observed that thymol is considerably more toxic against S. aureus than the other three terpenes, while carvacrol and p-cymene are the most inhibitory against E. coli. Thymol and carvacrol, but not gamma-terpinene and p-cymene, caused a concentration-dependent CF leakage from all kinds of LUVs employed; in particular, thymol was more effective on PC and PC/SA LUVS than on PC/PS vesicles, while carvacrol challenge evoked a CF leakage from PC/PS LUVs similar to that induced from PC/SA LUVs, and lower than that measured with PC vesicles. Concerning DSC experiments, these four terpenes caused a decrease in Tm and (especially carvacrol and p-cymene) DeltaH values, very likely acting as substitutional impurities. Taken together, our findings lead us to speculate that the antimicrobial effect of thymol, carvacrol, p-cymene, and gamma-terpinene may result, partially at least, from a gross perturbation of the lipidic fraction of the plasmic membrane of the microorganism. In addition to being related to the physicochemical characteristics of the compounds (such as lipophilicity and water solubility), this effect seems to be dependent on the lipidic composition and net surface charge of the microbic membranes. Furthermore, the compounds might cross the cell membranes, thus penetrating into the interior of the cell and interacting with intracellular sites critical for antibacterial activity.
Family Aware TV Program and Settings Recommender (2011)

In this paper we are proposing a design of TV program and settings recommendation engine utilizing contextual parameters like personal, social, temporal, mood and activity. In addition to the contextual parameters the system utilize the explicit or implicit user ratings and watching history to resolve the conflict if any while recommending the services .The System is implemented exploiting AI techniques ( like ontology, fuzzy logic ,Bayesian classifier and Rule Base) , RDBMS and SQL Query Processing . The motivation behind the proposed work is i) to improve the user's satisfaction level and ii) to improve the social relationship between user and TV. The context aware recommender utilizes social context data as an additional input to the recommendation task alongside information of users and tv programs. We have analyzed the recommendation process and performed a subjective test to show the usefulness of the proposed system for small families.
The traffic accident hotspot prediction: Based on the logistic regression method (2015)

Traffic accident has posed a threat to the safety of human life. Accident often occurs in some certain areas. In order to achieve the target of the identification and judgment of the accidents hotspots during driving, and improve the driving safety of vehicle and the traffic efficiency through early warning, a research was done based on the recent collected 400 sets of accidents data of 10 major roads in Beijing city. Through the statistics of the typical factors, and the Logistic regression analysis, the relationships between the traffic accident and the road type, the vehicle type, the driver state, the weather, the date etc., were studied. Finally, the prediction model of accident hotspot was established. The results show that the location of car in road transects, the road safety grade, the road surface condition, the visual condition, the vehicle condition and the driver state are the most significant factors which may lead to traffic accident. Meanwhile, the prediction model established in this paper was validated to be capable of predicting the occurrence of accident, and the prediction accuracy is approximate 86.67%. The study provides not only a theoretical basis for vehicle safety assistance driving, but also the guidance for collision avoidance and optimization for path planning of intelligent vehicle.
Monoclonal human thyroid cell line GEJ expressing human thyrotropin receptors. (1985)

By using the hybridoma technology, a monoclonal human thyroid cell line was obtained by fusing fresh normal human thyroid cells with a human lymphoblastoid cell line. The resultant cell line, called GEJ, has been selected for its expression of thyrotropin (TSH) receptors and has morphological and functional characteristics of normal human thyroid cells. In the presence or absence of human TSH, the GEJ cell line accumulates iodide, produces thyroid hormones, expresses thyroid membrane antigens, and binds approximately equal to 600 molecules of TSH per cell. The binding site for TSH has all the characteristics of specific receptor (i.e., temperature and time dependencies, dissociation of bound TSH only by high amounts of TSH, and a glycoprotein nature). Scatchard analysis described a curvilinear graph with two dissociation constants (Kd = 0.12 X 10(-9) M and 1.6 X 10(-9) M) with, respectively, 1.2 X 10(3) and 7.2 X 10(3) binding sites per cell. This human thyroid cell line that expresses TSH receptors could be a useful tool for the study of human thyroid disorders.
Cell death in bioreactors: A role for apoptosis (1994)

The incidence of apoptotic and necrotic cell death was compared in CHO, SF9 insect cells and murine plasmacytoma (J558L) and hybridoma (TB/C3) cells during in vitro cultivation in batch cultures. Acridine orange staining and fluorescence microscopy enabled the visualization of a classic morphological feature of apoptotic cell, the presence of condensed and/or fragmented chromatin. DNA gel electrophoresis was employed to show an additional characteristic of the process, the endonuclease-mediated fragmentation of DNA into multiples of 180 base pairs. The levels of apoptosis at the end of batch cultures of plasmacytoma and hybridoma cell lines were found to be 60% and 90% of total dead cells, respectively. However, employing the above-mentioned techniques, the biochemical and morphological features of apoptosis were not found in CHO and SF9 insect cells. Some factors affecting the induction of apoptosis during the batch culture of the hybridoma and plasmacytoma cell lines were identified. The most effective inducer was found to be glutamine limitation, followed by (in order of importance) serum limitation, glucose limitation, and ammonia toxicity. Blockage of the cell cycle of the plasmacytoma and hybridoma cells using thymidine resulted in the induction of apoptosis. This has important implications for the development of cell culture processes that minimize cell division and thereby increase specific productivity.
Transparent conductive indium oxide film deposited on low temperature substrates by activated reactive evaporation (1989)

High quality conductive coatings for the visible region were prepared on low temperature glass substrates. The conductive layer was an indium oxide film deposited by the activated reactive evaporation technique using a glow discharge hollow cathode ion gun. An antireflective layer of MgF(2) was deposited over the conductive layer. The average transmission in the visible region of the coated glass with sheet resistance of < 15 Omega/sq was greater than 90%. The coating was durable and passed a series of environmental tests according to MIL-C-675C.
