Multiple-Access Relay Channel with Network Coding and Non-Ideal Source-Relay Channels (2007)

The multiple-access relay channel (MARC) based on network coding has been proposed in recent papers as a means to achieve diversity gain in wireless networks, at the same time reducing the number of transmissions by a relay node. In MARC, multiple sources transmit to a common destination with the assistance of a single relay. In a network-coding-based realization of MARC, the relay merges the messages received from the two sources and forwards them to the destination; at the destination, the sources' messages can be recovered from either their direct transmissions or by performing additional network coding. In this work, performance analysis in the form of outage probability and coverage area, when non-ideal source-relay links exist, is performed. The relay is assumed to operate either in static or adaptive mode, and comparisons with the conventional MARC and point-to-point transmission are made. The outage results show that the conventional MARC system perform better when the source-relay links are high quality. Network-coding- based MARC operated in adaptive mode has better performance when the quality of the source-relay links are poor, and this system has better coverage area.
Registration of 3D objects and surfaces (1990)

An approach to the problem of comparative analysis of objects and their surfaces that arises in medical imaging is presented and illustrated with an application to postsurgical bone-graft separation. A common requirement in medical imaging applications is the registration of multiple representations of the object prior to mensuration. The modeling of the registration process and the registration system are described. The measurement of change in volume of bone grafts implanted inside the human body in a corrective surgical procedure is discussed, and the results are evaluated.< <ETX xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">></ETX>
Cell-division control in Escherichia coli: specific induction of the SOS function SfiA protein is sufficient to block septation. (1984)

Blocks in DNA replication cause a rapid arrest of cell division in Escherichia coli. We have previously established that the function SfiA (SulA), induced under these conditions as part of the SOS response, is involved in this inhibition of division. To separate the effects of SfiA from those of other SOS functions, we have constructed a plac-sfiA operon fusion, permitting specific induction of SfiA protein by addition of the lac operon inducer isopropyl beta-D-thiogalactopyranoside (IPTG). In lon mutants, in which the unstable SfiA protein has a longer half-life, IPTG caused a rapid arrest of cell division. Under these conditions, there is no concomitant induction of the SOS response. IPTG also caused a rapid arrest of cell division in lon+ strains. These results demonstrate that induction of the SfiA protein is sufficient to cause inhibition of division. Mutations in the sfiB gene can suppress IPTG-induced SfiA-mediated inhibition of division. At higher SfiA concentrations, however, even sfiB mutants cease division; an additional mutation genetically inseparable from sfiB restores normal division. These observations reinforce the hypothesis that the SfiB protein, probably required for cell septation, is the target of action of the SfiA division inhibitor.

Adaptive terminal synchronization in packet data networks (2003)

A method for network independent synchronization of CBO (continuous bit stream) terminals connected by a packet network is developed. The technique develops maximum-likelihood estimates of the transmitter bit rate and continuously adapts the receiver clock to maintain frequency lock with the transmitter. The method is no more difficult to implement than existing techniques but offers substantial advantages, including faster convergence, absence of nonlinearities, no explicit timing information carried in the packets, and compatibility with variable-length packets. Design equations are provided for selection of the parameters of the method to achieve a desired level of receiver clock jitter. The method is shown to be robust to lost packets. Simulation studies are used to confirm the analysis.< <ETX xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">></ETX>
[The effects of chloride channel blockers on thrombocytic cytoplasmic free calcium concentration and platelet aggregation]. (2005)

DIDS and NFA have no effect on the resting [Ca2+]i and the leak calcium influx of platelet. DIDS can inhibit the Ca2+ release, Ca2+ influx and PAG of platelet induced by thrombin, while NFA can only inhibit the Ca2+ release. The chloride channel and calcium channel blockers have interactions in affecting resting [Ca2+]i and PAG of platelet. The opening of chloride channel can influence the cellular calcium movement of platelet.

Combination therapy of schistosomiasis by tubercidin and nitrobenzylthioinosine 5'-monophosphate. (1983)

Nitrobenzylthioinosine 5'-monophosphate (NBMPR-P) inhibits the transport of nucleosides, including tubercidin, in mammalian systems but not in Schistosoma mansoni. Administration of NBMPR-P with high doses of tubercidin (lethal doses if injected alone) by intraperitoneal injection into S. mansoni-infected mice was highly toxic to the parasite but not to the host. Combination therapy resulted in a striking decrease in the number and copulation of worms. The few worms that could be found were so stunted that it was difficult to identify their sex. Mice receiving the combination of tubercidin plus NBMPR-P appeared healthy and had normal-sized livers and spleens. Combination therapy also caused a drastic decrease in the number of eggs in the liver (from 32,500 to 1,800 eggs per liver) and in the intestine (from 1,295 to 2 eggs per cm2). All eggs found were dead, indicating the termination of oviposition. Very few granulomas were detected in livers of treated animals. Sections of these livers showed lesions containing dead worms and what appeared to be a process of regeneration of normal tissue around old granulomas. Thus, combination therapy reduced the number and the progress of the primary pathological lesions associated with schistosomiasis. These results demonstrate that through combination therapy, highly selective toxicity against a parasite can be achieved. The effectiveness, simplicity, and practicality of host protection afforded by this method may yield a promising chemotherapeutic approach for the treatment of schistosomiasis and other parasitic diseases.
Chemical transformation of tylosin,a 16-membered macrolide,and its structure-activity relationship. (1982)

Tylosin is a 16-membered macrolide antibiotic used as veterinary antimicrobial agent. In this paper, we describe the structure of a novel condensation product obtained by acidic hydrolysis and alkaline treatment of tylosin, as well as the isolation of the aglycone part, tylonolide 5, 20-hemiacetal, by application of a modified Polonovski reaction to tylosin. Furthermore, we describe syntheses of the intermediates of tylosin biosynthesis and of related compounds, and also the relationship between the structure and antimicrobial activity.
Optical phase conjugation for time-domain undoing of dispersive self-phase-modulation effects (1983)

We show that the temporal distortion and spectral broadening of a pulse generated by the combined effects of group-velocity dispersion and self-phase modulation is removed by reflection of a cw-pumped, broadband, unityreflecting Kerr-like optical phase conjugator followed by retraversal of the nonlinear medium. We also examinenumerically the effects of finite linear loss in the material, of nonunity conjugate reflectivity, and of finite conjugator thickness.
Copper(II) Chloride Catalyzed Carboxydediazoniation of Arenediazonium Tetrafluoroborates with Carbon Monoxide in Aqueous Dioxane Solution to Arenecarboxylic Acids<sup>1</sup> (1990)

Arenecarboxylic acids were prepared by the copper(II) chloride catalyzed carboxydediazoniation of the corresponding arenediazonium tetrafluoroborates with carbon monoxide in aqueous dioxane solution. Preparative aspects of the reaction, as well as the mechanism involving modified Meerwein-type arylation of carbon monoxide, are discussed.
Information Security Challenge of QR Codes (2013)

The discipline of information security must adapt to new technologies and methods of interaction with those technologies. New technologies present both challenges and opportunities for the security professional, especially for areas such as digital forensics. Challenges can be in the form of new devices such as smartphones or new methods of sharing information, such as social networks. One such rapidly emerging interaction technology is the use of Quick Response (QR) codes. These offer a physical mechanism for quick access to Web sites for advertising and social interaction. This paper argues that the common implementation of QR codes potentially presents security issues that must be considered by professionals in the area. It analyzes potential privacy problems with QR codes and studies a range of devices as they may have implications for the processes and procedures used by Information Security professionals.

Glucocerebrosidase Inhibitors: Future Drugs for the Treatment of Gaucher Disease? (2014)

Gaucher disease is a progressive lysosomal storage disorder caused by a deficiency in the activity of β-glucocerebrosidase and is characterized by the accumulation of the glycosphingolipid glucosylceramide in the lysosomes of macrophages that leads to dysfunction in multiple organ system. An emerging strategy for the treatment of Gaucher disease is pharmacological chaperone therapy, based on the use of β-glucocerebrosidase inhibitors that are capable of enhancing residual hydrolytic activity at subinhibitory concentrations. In this article, the most common lysosomal storage disorder, Gaucher disease, is introduced and the current therapeutic strategies based on the use of enzyme inhibitors to ameliorate this disease are discussed, with a focus on the efforts being made toward finding and optimizing novel molecules as pharmacological chaperones for Gaucher disease that offer the promise to remedy this malady
Polystyrene and polymethacrylate resin-supported Jacobsen’s alkene epoxidation catalyst (2000)

Polystyrene and polymethacrylate-based resin supported Jacobsen’s chiral Mn salen complexes have been prepared. The resins are of defined molecular structure and morphology, and the complexes have been attached primarily in a pendant fashion. The loadings of Mn(III) are in the range ≈0.08–0.35 mmol g−1 to maximise the likelihood of site-isolation. The polymer-supported complexes have been used as enantioselective catalysts in the epoxidation of 1,2-dihydronaphthalene, indene, 1-phenylcyclohex-1-ene and 1-phenyl-3,4-dihydronaphthalene using m-chloroperbenzoic acid as the oxidant and 4-methylmorpholine N-oxide as the co-oxidant. Though the activities of the polymer catalysts are reduced relative to the soluble homogeneous analogue, the catalysts are sufficiently active to be useful. The corresponding reduction in enantioselectivity is more significant, and is both substrate and polymer resin dependent. However, in the case of 1-phenylcyclohex-1-ene and a macroporous polymethacrylate-based resin the enantioselectivity is equivalent to that of the soluble complex (91–92% ee). This is the first report of a polymer-supported analogue of Jacobsen’s catalyst being as selective as the homogeneous species. The catalysis data is discussed in detail in the context of the design of the polymer-supported system, and the existing data already available in the literature.
A prediction based handover trigger in overlapped heterogeneous wireless networks (2013)

Heterogeneous wireless networks are envisaged to be an integration of different wireless networks and demand the ability of users to move from one network domain to another network domain seamlessly. These networks are overlapped by each other to some extent. An appropriate time to initiate Handover (HO) is required to be calculated based on the necessity of HO as well as availability of target network. The link down trigger and link up trigger are the points corresponding to the HO requirement and resource availability respectively. In this paper, a prediction based HO trigger is proposed to initiate HO procedure at appropriate time. Matlab Simulation results demonstrate significant improvement in HO performance in different network overlapping environments.
Holographic Recording on Electron Beam Colored Sodium Chloride Crystals (1970)

Color centers produced in sodium chloride crystals by electron beam bombardment have been used for holographic recording. The holograms were constructed with the 4762-A radiation of a krypton ion laser. Reconstruction was demonstrated with both the 4762-A and 5682-A radiation of the same laser. The possibility of reconstruction in the M band, centered at 7350 A, was postulated but was not demonstrated. It was shown that the electron beam coloring technique converts complex R and M centers formed by bleaching back to F centers, making the crystals reusable. The efficiency of the electron beam coloring process and the penetration depth of the color centers as a function of the accelerating voltage were determined.

Characterising the pressure-leakage response of pipe networks using the FAVAD equation (2015)

This study investigated the feasibility of characterising the pressure-leakage response of water distribution systems using the FAVAD (Fixed and Variable Area Discharges) equation, instead of the conventional N1 power equation. The study was based on 300 network models with randomly distributed leaks and 35 networks generated through a sensitivity analysis. It was found that the leakage rate and average zone pressure head (AZP) before and after pressure reduction may be used in conjunction with the FAVAD equation to estimate the initial leakage area (A0S) and head-area slope (mS) of any system. In addition, A0S and ms were shown to provide good estimates respectively of the sum of the initial areas and head-area slopes of all the individual leaks in the system. The study found that a dimensionless leakage number may be calculated for any system and used to characterise the pressure-leakage response. Finally, the study showed that it is possible to convert between N1 and the leakage number using a simple equation.
Spontaneous splicing mutations at the dihydrofolate reductase locus in Chinese hamster ovary cells. (1986)

We isolated and characterized three spontaneous mutants of Chinese hamster ovary cells that were deficient in dihydrofolate reductase activity. All three mutants contained no detectable enzyme activity and produced dihydrofolate reductase mRNA species that were shorter than those of the wild type by about 120 bases. Six exons are normally represented in this mRNA; exon 5 was missing in all three mutant mRNAs. Nuclease S1 analysis of the three mutants indicated that during the processing of the mutant RNA, exon 4 was spliced to exon 6. The three mutant genes were cloned, and the regions around exons 4 and 5 were sequenced. In one mutant, the GT dinucleotide at the 5' end of intron 5 had changed to CT. In a second mutant, the first base in exon 5 had changed from G to T. In a revertant of this mutant, this base was further mutated to A, a return to a purine. Approximately 25% of the mRNA molecules in the revertant were spliced correctly to produce an enzyme with one presumed amino acid change. In the third mutant, the AG at the 3' end of intron 4 had changed to AA. A mutation that partially reversed the mutant phenotype had changed the dinucleotide at the 5' end of intron 4 from GT to AT. The splicing pattern in this revertant was consistent with the use of cryptic donor and acceptor splice sites close to the original sites to produce an mRNA with three base changes and a protein with two amino acid changes. These mutations argue against a scanning model for the selection of splice site pairs and suggest that only a single splice site need be inactivated to bring about efficient exon skipping (a regulatory mechanism for some genes). The fact that all three mutants analyzed exhibited exon 5 splicing mutations indicates that these splice sites are hot spots for spontaneous mutation.
Nanoscale Patterning of Two Metals on Silicon Surfaces Using an ABC Triblock Copolymer Template (2006)

Patterning technologically important semiconductor interfaces with nanoscale metal films is important for applications such as metallic interconnects and sensing applications. Self-assembling block copolymer templates are utilized to pattern an aqueous metal reduction reaction, galvanic displacement, on silicon surfaces. Utilization of a triblock copolymer monolayer film, polystyrene-block-poly(2-vinylpyridine)-block-poly(ethylene oxide) (PS-b-P2VP-b-PEO), with two blocks capable of selective transport of different metal complexes to the surface (PEO and P2VP), allows for chemical discrimination and nanoscale patterning. Different regions of the self-assembled structure discriminate between metal complexes at the silicon surface, at which time they undergo the spontaneous reaction at the interface. Gold deposition from gold(III) compounds such as HAuCl4(aq) in the presence of hydrofluoric acid mirrors the parent block copolymer core structure, whereas silver deposition from Ag(I) salts such as AgNO3(aq) does the opposite, localizing exclusively under the corona. By carrying out gold deposition first and silver second, sub-100-nm gold features surrounded by silver films can be produced. The chemical selectivity was extended to other metals, including copper, palladium, and platinum. The interfaces were characterized by a variety of methods, including scanning electron microscopy, scanning Auger microscopy, X-ray photoelectron spectroscopy, and atomic force microscopy.
