A proactive routing protocol for wireless ad hoc networks assuring some privacy (2013)

In most networks, it is simple to find the identity of participants communicating with each other or to link packet flows together. Our objective is to develop a proactive routing protocol for ad hoc networks preserving the anonymity of the nodes as much as possible and assures the unlinkability of packet flows between two given nodes. In order to develop practical solutions, we propose to accept that the identity of the nodes would not be perfectly hidden.
A New Polysilicon CMOS Self-Aligned Double-Gate TFT Technology (2005)

In this paper, a new polysilicon CMOS self-aligned double-gate thin-film transistor (SA-DG TFT) technology is proposed and experimentally demonstrated. The self-alignment between the top- and bottom-gate is realized by a backlight exposure technique. The structure has an ultrathin channel region (300 /spl Aring/) and a thick source/drain region. Experimental results show that this technology provides excellent current saturation due to a combination of the effective reduction in the drain field and the full depletion of the ultrathin channel. Moreover, for n-channel devices, the SA-DG TFT has a 4.2 times higher on-current (V/sub gs/=20V) as compared to the conventional single-gate TFT. Whereas for the p-channel devices, the SADG TFT has a 3.6 times higher on-current (V/sub gs/=-20V) compared to the conventional single-gate device.
Periodic Structure of a Single Sheet of a Clothlike Macromolecule (Atomic Cloth) Studied by Scanning Tunneling Microscopy (1997)

Fused parallelogrammic rings sharing all sides are seen in the structure of 1 (shown below). This atomic cloth was prepared by photopolymerizing alkatetryne molecules that were vapor-deposited and laid flat on graphite. The structural fit between the atomic cloth and the substrate, observed by scanning tunneling microscopy, enables one to determine the unit mesh.

A Universal Standard for the Validation of Blood Pressure Measuring Devices (2018)

In the past 30 years, several organizations, such as the US Association for the Advancement of Medical Instrumentation (AAMI), the British Hypertension Society, the European Society of Hypertension (ESH) Working Group on Blood Pressure (BP) Monitoring, and the International Organization for Standardization (ISO), have developed protocols for clinical validation of BP measuring devices. However, it is recognized that science, as well as patients, consumers, and manufacturers, would be best served if all BP measuring devices were assessed for accuracy according to an agreed single validation protocol that had global acceptance. Therefore, an international initiative was taken by the AAMI, ESH, and ISO experts who agreed to develop a universal standard for device validation. This statement presents the key aspects of a validation procedure, which were agreed by the AAMI, ESH, and ISO representatives as the basis for a single universal validation protocol. As soon as the AAMI/ESH/ISO standard is fully developed, this will be regarded as the single universal standard and will replace all other previous standards/protocols.
Chapter 15 Forensic science (2011)

Extract Introduction to forensic science Context It is not the purpose of this book to provide instruction in the forensic sciences. However, it cannot be over-emphasized that forensic investigation is a multidisciplinary team effort and it is imperative that individual members of the team have at least an elementary understanding of the roles of experts in other disciplines. Not only does this ensure that evidence gathering, analysis, and interpretation is carried out efficiently and effectively, but it also goes some way to ensuring that expert witnesses in a court setting are, indeed, experts in the subjects to which they speak. Definition What is meant by the term 'forensic science'? Arguably, there is no such thing, if the term is intended to refer to a separate and clearly defined discipline. Forensic science is really an umbrella description relating to the practice of any science within a legal context. It is worth emphasizing that good forensic science is, therefore, nothing other than good science applied to a forensic context.
Synthesis of 1,4-Diazepine Nucleosides (2002)

The phenolic b-diketones I prepared by modified Baker-Venkataraman rearrangement were converted to the flavones II in acidic medium which on treatment with aqueous ethylenediamine/propylenediamine gave diazepine derivatives III. After coupling with acetobromo sugars in the presence of mercuric cyanide and nitromethane, deacetylation in methanolic ammonia yielded nucleosides V. The structures of all the intermediates and final products were confirmed with the help of modern spectroscopic techniques.

Studies on a lysogenic <i>Bacillus</i> strain. I. A Bacteriophage specific for <i>Bacillus anthracis</i> (1951)

A bacteriophage is described which attacks almost exclusively strains of Bacillus anthracis , and attacks all the strains of this species which have been tested. As well as attacking typical strains of this species it attacks atypical variants. Strains of B. anthracis are not attacked by this phage when they are in a muciod state. A few strains of B. anthracis are only feebly attacked by this phage. Some experiments, conducted in an attempt to discover the reason for this, are described. The results are discussed and arguments in favour of regarding B. anthracis as a valid species are put forward.
Dry SO/sub 2/ scrubbing at Antelope Valley, ND, power station (1979)

Pilot-plant studies of the Niro Atomizer A.S./Joy Manufacturing Co. soda ash or lime-slurry dry desulfurization system at a Minnesota powerplant preceded Basin Electric Power Cooperative's choice of the process for a 440 MW, lignite-fired unit at its Antelope Valley station near Bismarck, ND. The pilot-plant work showed that dry scrubbing would meet the EPA New Source Performance Standards for SO/sub 2/ removal and that the system would be simpler to operate, need less complex equipment, hence, more available than a wet scrubber. The $47 million advantage of the dry over a wet system is site-specific. Some of the features of the Joy/Niro system are the recycle of a portion of the spent chemicals and fly ash to the fresh feed, thereby saving time; the use of a single rotary atomizer centered in the spray dryer absorber; the compound gas disperser design; and the Joy stepped tube sheet baghouse design.
A Second Generation In-Car Tire Pressure Monitoring System Based on Wireless Passive SAW Sensors (2006)

A complete pre-production in-car tire pressure monitoring system, employing 433 MHz SAW resonators as sensing elements is presented in this paper. The SAW sensing element incorporating three one-port resonators fabricated on a single substrate and connected to an antenna is described, along with calibration models for the sensor. An issue of sensor antenna tuning and sensor matching is investigated. A method of SAW sensor wireless interrogation is presented and the electronic interrogation unit is described. Experimental data characterizing accuracy of the remote resonant frequency measurement is presented
The relationship between placental protein synthesis and transfer of amino acids (1983)

The relationship between placental protein synthesis and transfer of amino acids from mother to foetus was studied in the guinea pig, by using [U-14C]-lysine, -leucine, -glycine, -aspartate and -alpha-aminoisobutyrate. The uptake of label by protein was 12-16% of total label transferred. Cycloheximide inhibited incorporation of all naturally occurring amino acids into protein by 81-96% and transfer by 62-75%; the concentration of label in the free pool was increased for each. These findings were confirmed when specific-radioactivity measurements were made with L-[U-14C]lysine. The transfer of the non-protein amino acid alpha-aminoisobutyrate was not significantly decreased by cycloheximide. A model, linking protein synthesis to the generation of a transfer pool of amino acids, is proposed whereby inhibition of protein synthesis decreases the amount of amino acid available for transfer.
Bile acids in laryngopharyngeal refluxate: Will they enhance or attenuate the action of pepsin? (2012)

At the levels and pH that pepsin and bile acids might occur in an LPR event, bile acids do not attenuate pepsin activity. Pepsin could be considered a damaging factor even at high pH, and it will aggravate further any damaging effects of bile acids in the refluxate. Laryngoscope, 2012.
&#x2113;<inf>p</inf> norm multiple kernel Fisher discriminant analysis for object and image categorisation (2010)

In this paper, we generalise multiple kernel Fisher discriminant analysis (MK-FDA) such that the kernel weights can be regularised with an ℓ <sub xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">p</sub> norm for any p ≥ 1, in contrast to existing MK-FDA that uses either l1 or l2 norm. We present formulations for both binary and multiclass cases and solve the associated optimisation problems efficiently with semi-infinite programming. We show on three object and image categorisation benchmarks that by learning the intrinsic sparsity of a given set of base kernels using a validation set, the proposed ℓ <sub xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">p</sub> MK-FDA outperforms its fixed-norm counterparts, and is capable of producing state-of-the-art performance. Moreover, we show that our ℓ <sub xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">p</sub> MK-FDA outperforms the ℓ <sub xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">p</sub> multiple kernel support vector machine (ℓ <sub xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">p</sub> MK-SVM) which has been recently proposed. Based on this observation and our experience with single kernel FDA and SVM, we argue that the almost century-old FDA is still a strong competitor of the popular SVM.

Detection of terahertz radiation from longitudinal optical phonon–plasmon coupling modes in InSb film using an ultrabroadband photoconductive antenna (2000)

Terahertz radiation from longitudinal optical (LO) phonon–plasmon coupling modes in InSb films is observed using an ultrafast photoconductive antenna detector. We demonstrate a response frequency of up to 7 THz for a low-temperature-grown GaAs-based photoconductive antenna gated with 25 fs laser pulses. It is found that the emission frequencies of the coupling modes are dependent only on the residual carrier density, not on the excitation carrier density. It is also found that the LO phonon–plasmon oscillations in semiconductors can serve as an efficient THz source.
Reconfigurable Riser - Enabling Drilling Solutions for the Future (2005)

Drilling offshore oil and gas wells has become increasingly challenging as water and well depths have increased. In many regions, drilling hazards such as very narrow margins between collapse (pore) and fracture pressures, pore pressure uncertainty, pore pressure regression, high pressure and high temperature have resulted in significant additional cost due to the time required to rectify the problems associated with these hazards.
Design and synthesis of new transition-state analog inhibitors of aspartate transcarbamylase (1985)

Six transition-state or bisubstrate analogue inhibitors (6-11) have been designed, synthesized, and tested against aspartate transcarbamoylase (ATCase). Several of these inhibitors, 7-9, were designed as analogues of N-(phosphonoacetyl)-L-aspartate (PALA, 5a) and incorporated a tetrahedral sulfur group (-S-, -SO-, -SO2-) alpha to a phosphonic acid moiety. Synthesis of 7-9 was accomplished with a new reagent, diethyl (mercaptomethyl)phosphonate (19). Thiol addition of 19 to diethyl itaconate or other olefins proves a new general synthetic route to (thiomethyl)-phosphonate analogues of acyl phosphates or diphosphate anhydrides. Analysis of the observed inhibition kinetics with ATCase and structural modeling studies indicate that increased steric size of the sulfur moieties in the sulfide 7, sulfoxide 8, sulfone 9, and sulfonamide 10 may cause these compounds to be less potent inhibitors of Escherichia coli ATCase than N-(phosphonoacetyl)-L-aspartate (PALA, 5a). The pKa of the carbonyl groups (or S-analogue thereof) may be a key factor in determining the affinity of ATCase for inhibitor. The distance from the alpha-carbon to the phosphorus atom was judged to be a less important factor in determining the tightness of inhibitor binding since no significant change in the inhibition constant (Ki) occurred upon elimination of the alpha-methylene group in sulfide 7 to give sulfide 11. The ester analogue of PALA (5a), O-(phosphonoacetyl)-L-malic acid (6), exhibited a Ki of 2 X 10(-6) M.
Preparation of Ag/PVP Nanocomposites as a Solid Precursor for Silver Nanocolloids Solution (2010)

A polyvinylpyrrolidone (PVP)/Ag nanocomposites was prepared by the simultaneous thermal reduction and radical polymerization route. The in situ synthesis of the Ag/PVP nanocomposites is based on the finding that the silver n-propylcarbamate (Ag-PCB) complex can be directly dissolved in the NVP monomer, and decomposed by only heat treatment in the range of 110 to <TEX>$130^{\circ}C$</TEX> to form silver metal. Silver nanoparticles with a narrow size distribution (5 - 40 nm) were obtained, which were well dispersed in the PVP matrix. A successful synthesis of Ag/PVP nanocomposites then proceeded upon heat treatment as low as <TEX>$110^{\circ}C$</TEX>. Moreover, important advantages of the in situ synthesis of Ag/PVP composites include that no additives (e.g. solvent, surface-active agent, or reductant of metallic ions) are used, and that the stable silver nanocolloid solution can be directly prepared in high concentration simply by dissolving the Ag/PVP nanocomposites in water or organic solvent.

Epitaxial Deposition Techniques. (1971)

A two-year program for development of epitaxial deposition techniques for the growth of thin films of semiconductor and piezoelectric materials for use in surface-wave acoustic devices is described. The work of the first eighteen months is summarized briefly; the final six months of the program is discussed in detail, with emphasis on acoustic device fabrication and evaluation in ZnO and AlN films. The program has emphasized chemical vapor deposition of ZnO, AlN and GaAs, prepared by metalorganic-hydride reactions, on substrates of LiNbO3, Si, Al2O3, and certain other semiconductor and piezoelectric materials.
Metabolic activation of N-acylanthracyclines precedes their interaction with DNA topoisomerase II. (1987)

The N-acylanthracyclines AD32 (N-trifluoroacetyladriamycin-14-valerate) and AD143 (N-trifluoroacetyladriamycin-14-O-hemiadipate) are analogs of Adriamycin (ADR) undergoing clinical or advanced pre-clinical screening. Their principal metabolites, following the cleavage of the 14-acyl side-chain, are N-trifluoroacetyladriamycin (AD41) and its reduced form N-trifluoroacetyladriamycinol (AD92). Both these compounds are biologically active and detectable in treated patients, laboratory animals, and in tissue culture cells. Unlike ADR, AD32, as well as AD143 and metabolites, show no detectable binding to double-strand DNA. Their effects on DNA have been previously investigated in vivo and in vitro using the alkaline filter-elution assay. It has been shown that all of the compounds cause approximately equivalent amounts of protein-associated DNA breaks (PAB) and DNA-protein crosslinks in a mouse lymphoma and in tissue-culture leukemia cells. In order to establish whether the induction of PAB by the drugs requires DNA topoisomerase II mediation, cleavage mapping analysis was done with tested compounds using purified human topoisomerase II. DNA fragmentation was significantly enhanced in the presence of the enzyme and either AD41 or AD92. In contrast, no fragmentation enhancement was observed in the presence of the parental drugs AD32 or AD143. The results strongly suggest that metabolic activation of N-acylanthracyclines by nonspecific esterases is a prerequisite for their interaction with DNA topoisomerase II and for stabilization of the cleavable complex.
Effects of antagonists at the human recombinant P2X<sub>7</sub> receptor (1998)

1. We have used whole-cell patch clamping methods to examine the properties of the recombinant human P2X7 (P2Z) receptor stably expressed in HEK-293 cells. 2. In an extracellular solution with lowered concentrations of divalent cations (zero Mg2+ and 0.5 mM Ca2+), both ATP and the nucleotide analogue, 2'- and 3'-O-(4-benzoylbenzoyl)-adenosine 5'-triphosphate (Bz-ATP) evoked concentration-dependent whole-cell inward currents with maxima of 4658+/-671 and 5385+/-990 pA, respectively, at a holding potential of -90 mV. Current-voltage relationships determined using 100 microM Bz-ATP reversed at -2.7+/-3.1 mV, and did not display significant rectification. 3. Repeated applications of 300 microM Bz-ATP produced inward currents with similar rise-times (approx. 450 ms, 5-95% current development) but with progressively slower 95-5% decay times, with the eighth application of this agonist yielding a decay time of 197% of the first application. 4. Concentration-effect curves to ATP and Bz-ATP produced estimated EC50 values of 780 and 52.4 microM, respectively. Consecutive concentration-effect curves to Bz-ATP produced curves with similar maxima and EC50 values. 5. The non-selective P2 antagonists, pyridoxal-phosphate-6-azophenyl-, 2',4'-disulphonic acid (PPADS) and suramin, both produced concentration-dependent increases in maximal inward currents to Bz-ATP, with IC50 concentrations of approximately 1 microM and 70 microM, respectively. The profile of antagonism produced by PPADS was not that of a competitive antagonist. 6. The isoquinolene derivatives 1-(N,O-bis[5-isoquinolinesulphonyl]-N-methyl-L-tyrosyl)-4-phenylpi perazine (KN-62) and calmidazolium both produced antagonism which was not competitive, with IC50 concentrations of approximately 15 and 100 nM, respectively. HMA (5-(N,N-hexamethylene)- amiloride) was also an effective antagonist at a concentration of 10 microM. The group IIb metal, copper, also displayed antagonist properties at the human P2X7 receptor, reducing the maximum response to Bz-ATP by about 50% at a concentration of 1 microM. 7. These data demonstrate that the human recombinant P2X7 receptor displays functional behaviour which is similar to the recombinant rat P2X7 receptor, but has a distinct pharmacological profile with respect to agonist and antagonist sensitivity.
Software-Defined Radio LTE Positioning Receiver Towards Future Hybrid Localization Systems (2013)

The appropriate positioning characteristics and fast deployment of Long Term Evolution (LTE) systems makes this technology a promising candidate towards future satellite and terrestrial hybrid scenario. Nevertheless, further studies on the achievable LTE positioning capabilities are still necessary for commercial or realistic network deployments. This paper describes a tool that provides standalone localization in LTE networks. The tool is a software-defined radio (SDR) receiver working at the LTE physical layer, performing acquisition, tracking and positioning. The SDR LTE positioning receiver is validated in a static scenario, showing position errors below three meters in the absence of multipath for a signal bandwidth of 1.08 MHz.
Single-bit compressive imaging system for the mmW and THz bands (2017)

We present, a novel 64 × 64-pixel imaging system utilizing a low-cost single-bit comparator sensor and a compressive sensing algorithm for mmW and THz bands. To validate the proposed methodology, a photoexcited high-resistivity Silicon wafer is used as the spatial light modulator and a 2-port vector network analyzer is used as the source-receiver pair. Recording only the “sign” of the measured signal, the proposed approach can reconstruct 4K-pixel image of the scene using only 1,024 measurements at 690 GHz.
