Modeling and prototyping dynamically reconfigurable systems for efficient computation of dynamic programming methods by rewriting-logic (2004)

Systolic arrays provide a large amount of parallelism. However, their applicability is restricted to a small set of computational problems due to their lack of flexibility. This limitation can be circumvented by using reconfigurable systolic arrays, where the node interconnections and operations can be redefined even at run time. In this context, several alternative systolic architectures can be explored and powerful tools are needed to model and evaluate them. We show how well-known rewriting-logic environments could be used to quickly model and simulate complex application specific digital systems speeding-up its subsequent prototyping. We show how to use rewriting-logic to model and evaluate reconfigurable systolic architectures which are applied to the efficient treatment of several dynamic programming methods for resolving well-known problems such as global and local sequence alignment (Smith-Waterman algorithm), approximate string matching and computation of the longest common subsequence. A VHDL description of the conceived architecture was implemented from the rewriting-logic based abstract models and synthesized over an FPGA of the APEX family.
Eye tracking based driver fatigue monitoring and warning system (2011)

The main idea behind this project is to develop a non-intrusive system which can detect fatigue of the driver and issue a timely warning. Since a large number of road accidents occur due to the driver drowsiness. Hence this system will be helpful in preventing many accidents, and consequently save money and reduce personal suffering. This system will monitor the driver's eyes using camera and by developing an algorithm we can detect symptoms of driver fatigue early enough to avoid accident. So this project will be helpful in detecting driver fatigue in advance and will gave warning output inform of sound and seat belt vibration whose frequency will vary between 100 to 300 Hzs. Moreover the warning will be deactivated manually rather than automatically. So for this purpose a deactivation switch will be used to deactivate warning. Moreover if driver felt drowsy there is possibility of sudden acceleration or deacceleration hence we can judge this by Plotting a graph in time domain and when all the three input variables shows a possibility of fatigue at one moment then a Warning signal is given in form of text or red colour circle. This will directly give an indication of drowsiness/fatigue which can be further used as record of driver performance.
RuCl<sub>3</sub>-Catalyzed Regioselective Diarylation with Aryl Tosylates via C-H Activation (2013)

Abstract The direct arylation of arylpyridines with aryl tosylates was carried out smoothly in the presence of 2.5 mol% RuCl3 using MesCOOH as crucial promoter to generate biarylated products. The method is simple, efficient, safe, and regioselective, can be performed in the absence of expensive ligands, and does not require any precautions with regard to the exclusion of air and moisture. The biarylated products were obtained in good yields. Supplemental materials are available for this article.

A Web Services Façade for an Open Source ERP System (2006)

Web services are becoming a popular means of realizing service-oriented architectures. In enterprise resource planning (ERP), web services can enhance the flexibility of ERP systems by making them accessible from other programs over the Internet. This paper presents an approach on providing a web service interface to an open source ERP system (Compiere). After a short introduction, the implementation of a web services facade for Compiere is discussed. To facilitate access to Compiere’s business logic and pertinent data from external systems, this implementation provides interfaces in the form of web services to enable the visibility in supply networks that is needed by supply chain management (SCM) applications. The interface exposes a simplified facade that reduces Compiere’s complexity and decreases network traffic by aggregating numerous fine-grained method calls. Potentials and problems of this approach are discussed in the paper.
Systematic identification of interactions between host cell proteins and E7 oncoproteins from diverse human papillomaviruses (2012)

More than 120 human papillomaviruses (HPVs) have now been identified and have been associated with a variety of clinical lesions. To understand the molecular differences among these viruses that result in lesions with distinct pathologies, we have begun a MS-based proteomic analysis of HPV-host cellular protein interactions and have created the plasmid and cell line libraries required for these studies. To validate our system, we have characterized the host cellular proteins that bind to the E7 proteins expressed from 17 different HPV types. These studies reveal a number of interactions, some of which are conserved across HPV types and others that are unique to a single HPV species or HPV genus. Binding of E7 to UBR4/p600 is conserved across all virus types, whereas the cellular protein ENC1 binds specifically to the E7s from HPV18 and HPV45, both members of genus alpha, species 7. We identify a specific interaction of HPV16 E7 with ZER1, a substrate specificity factor for a cullin 2 (CUL2)-RING ubiquitin ligase, and show that ZER1 is required for the binding of HPV16 E7 to CUL2. We further show that ZER1 is required for the destabilization of the retinoblastoma tumor suppressor RB1 in HPV16 E7-expressing cells and propose that a CUL2-ZER1 complex functions to target RB1 for degradation in HPV16 E7-expressing cells. These studies refine the current understanding of HPV E7 functions and establish a platform for the rapid identification of virus-host interactions.
Evidence for Cyclic Di-GMP-Mediated Signaling in Bacillus subtilis (2012)

Cyclic di-GMP (c-di-GMP) is a second messenger that regulates diverse cellular processes in bacteria, including motility, biofilm formation, cell-cell signaling, and host colonization. Studies of c-di-GMP signaling have chiefly focused on Gram-negative bacteria. Here, we investigated c-di-GMP signaling in the Gram-positive bacterium Bacillus subtilis by constructing deletion mutations in genes predicted to be involved in the synthesis, breakdown, or response to the second messenger. We found that a putative c-di-GMP-degrading phosphodiesterase, YuxH, and a putative c-di-GMP receptor, YpfA, had strong influences on motility and that these effects depended on sequences similar to canonical EAL and RxxxR-D/NxSxxG motifs, respectively. Evidence indicates that YpfA inhibits motility by interacting with the flagellar motor protein MotA and that yuxH is under the negative control of the master regulator Spo0A∼P. Based on these findings, we propose that YpfA inhibits motility in response to rising levels of c-di-GMP during entry into stationary phase due to the downregulation of yuxH by Spo0A∼P. We also present evidence that YpfA has a mild influence on biofilm formation. In toto, our results demonstrate the existence of a functional c-di-GMP signaling system in B. subtilis that directly inhibits motility and directly or indirectly influences biofilm formation.
On the dynamical theory of gratings (1907)

Abstract In the usual theory of gratings, upon the lines laid down by Fresnel, the various parts of the primary wave-front after undergoing influences, whether affecting the phase or the amplitude, are conceived to pursue their course as if they still formed the fronts of waves of large area. This supposition, justifiable as an approximation when the grating interval is large, tends to fail altogether when the interval is reduced so as to be comparable with the wave-length. A simple example will best explain the nature of the failure. Consider a grating of perfectly reflecting material whose alternate parts are flat and parallel and equally wide, but so disposed as to form a groove of depth equal to a quarter wave-length, and upon this let light be incident perpendicularly. Upon Fresnel’s principles the central regularly reflected image must vanish, being constituted by the combination of equal and opposite vibrations. If the grating interval be large enough, this conclusion is approximately correct and could be verified by experiment. But now suppose that the grating interval is reduced until it is less than the wavelength of the light. The conclusion is now entirely wide of the mark. Under the circumstances supposed there are no lateral spectra and the whole of the incident energy is necessarily thrown into the regular reflection, which is accordingly total instead of evanescent. A closer consideration shows that the recesses in this case act as resonators in a manner not covered by Fresnel’s investigations, and illustrates the need of a theory more strictly dynamical. The present investigation, of which the interest is mainly optical, may be regarded as an extension of that given in ‘Theory of Sound,’* where plane waves were supposed to be incident perpendicularly upon a regularly corrugated surface, whose form was limited by a certain condition of symmetry. Moreover, attention was there principally fixed upon the case where the wave-length of the corrugations was long in comparison with that of the waves themselves, so that in the optical application there would be a large number of spectra. It is proposed now to dispense with these restrictions. On the other hand, it will be supposed that the depth of the corrugations is small in comparison with the length (λ) of the waves.
Comparative Study on Strain-Induced Crystallization Behavior of Peroxide Cross-Linked and Sulfur Cross-Linked Natural Rubber (2008)

Strain-induced crystallization (SIC) behavior of natural rubber (NR) cross-linked by peroxide or sulfur was comparatively studied by time-resolved wide-angle X-ray diffraction measurements at SPring-8. Stretching ratio at the onset of SIC (αc) decreased with an increase of network chain density (ν) for peroxide cross-linked NR (P-NR), while it remained constant for sulfur cross-linked NR (S-NR). But, dependence of relative crystallization rates on ν was similar for both P-NR and S-NR. Calculated entropy differences between the undeformed and the deformed states (ΔSdef) at αc were equal for P-NR regardless of ν, whereas it became smaller with the increase of ν for S-NR. The SIC behavior of P-NR is in agreement with the prediction on homogeneous or uniform networks by Flory. Thus, the network structure of S-NR is supposed to be less homogeneous than that of P-NR. The inhomogeneity in S-NR is estimated due to the presence of domains of high ν value embedded in the rubbery network matrix, which is supported by the stress dependences of apparent lateral crystallite size. The mechanical characteristics of S-NR and P-NR are also discussed from the viewpoint of their SIC behaviors on the basis of the network structures.
Laser cooling of CdS nanobelts: Thickness matters (2013)

We report on the thickness dependent laser cooling in CdS nanobelts pumped by a 532 nm green laser. The lowest achievable cooling temperature is found to strongly depend on thickness. No net cooling can be achieved in nanobelts with a thickness below 65 nm due to nearly zero absorption and larger surface nonradiative recombination. While for nanobelts thicker than ~120 nm, the reabsorption effect leads to the reduction of the cooling temperature. Based on the thickness dependent photoconductivity gain, mean emission energy and external quantum efficiency, the modeling of the normalized temperature change suggests a good agreement with the experimental results.

Male Anorgasmia Treated with Oxytocin (2008)

Introduction. This is a case report on male anorgasmia that was successfully treated with oxytocin. Oxytocin is increased during arousal and peaks during orgasm. More recently, a study on humans published in Nature has shown its value in social bonding, increasing trust, and enhancing the sense of well-being. Aim. To test the effectiveness of administering oxytocin in a case of treatment-resistant anorgasmia. Methods. The patient underwent a biopsychosocial evaluation by a psychiatrist trained in sexual medicine and sex therapy for male orgasmic disorder, acquired type. Medical conditions, effect of substances, and psychological issues were ruled out. The patient was properly consented to using oxytocin as an off-label trial. Oxytocin was administered using a nasal spray intracoitally because of its ultra-short half-life. Results. Oxytocin was effective in restoring ejaculation. Conclusions. A case of treatment-resistant male anorgasmia was successfully treated with intracoital administration of intranasal oxytocin.
Secure and Tamper Proof Code Management (2014)

In this paper, we present an additional layer of security to source code repositories by combining Keyless Signature Infrastructure (KSI) with Git to protect against insider threats as well as provide security even in the event of a private key compromise. This work was done to show the minimal effort required to integrate these two technologies to provide additional security to software development efforts using Git compared to the security benefit gained. Additionally, we designed the solution to minimize the impact to the current Git workflow, requiring no additional commands when committing code and only one new command to verify past commits.

An Investigation on the Simultaneous Reduction of Particulate and NOx by Controlling Both the Turbulence and the Mixture Formation in DI Diesel Engines (1993)

<div class="htmlview paragraph">This paper presents experimental results of the reduction of both particulate and NOx emitted from direct injection diesel engines by a two stage combustion process. The primary combustion is made very rich to reduce NOx and then the particulate is oxidized by strong turbulence generated during the secondary combustion. The rich mixture is formed by low pressure fuel injection and a small cavity combustion chamber configuration. The strong turbulence is generated by a jet of burned gas from an auxiliary chamber installed at the cylinder head. The results showed that NOx was reduced significantly while maintaining fuel consumption and particulate emissions. An investigation was also carried out on the particulate reduction process in the combustion chamber with the turbulence by gas sampling and in-cylinder observation with an optical fiber scope and a high speed camera.</div>
Practical approaches to maintaining referential integrity in multidatabase systems (1993)

An important problem in multidatabase systems is maintaining semantic integrity constraints among the multiple databases in the system. The paper investigates practical approaches to enforcing referential integrity, one of the most important classes of constraints. Referential integrity is important in its own right and also provides a good starting point for studying more general classes of constraints. The semantics of referential integrity are relatively well known and understood, yet they have much in common with more general classes of constraints. The paper considers what enforcement mechanisms can be used in the context of the transaction models or interaction models which are widely found in practice today: the queued message model, the remote procedure call model, the distributed transaction model, and the local transaction dialog model.< <ETX xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">></ETX>

Optical Properties of Quantized Semiconductor Particles (1996)

CdS nanoclusters ranging in diameters between 1 and 4 nm were prepared i aqueous solution using aliphatic mercaptoalcohols as ligands. The photon energies of the 1s1s absorption and the respective oscillator strengths are in accordance with size quantization theory. Nonlinear optical properties are discussed in terms of the influence of trapped charge carriers on the excitonic transition. Onion-shell-like composite particles from CdS and HgS were prepared by successive substitution and reprecipitation processes. Particles with a core radius of 2 nm, a shell of up to 1 nm HgS followed by a final shell of up to 1.5 nm CdS were obtained. Electrons and holes were localized in the HgS shell, giving rise to excitonic fluorescence. Dense, yet randomly packed, nanoparticulate ZnO films were found to show reversible optical changes upon cathodic polarization. Some cluster species crystallize in the form of macroscopic three-dimensional superlattices, which were investigated by single-crystal X-ray analysis. The neutral Cd$\_{17}$S$\_{4}$(RS)$_{26}$ clusters are covalently linked in the superlattice, the structure of which exhibits self-similarity to the interior structure of the clusters.

An intelligent mobile network (IMN) configuration and a personal mobile telecommunication (PMT) scheme for network enhancement are proposed. This system was introduced commercially in Japan in March 1993. The commercial introduction of the system is described.
Association Between Overactive Bladder and Polyneuropathy in Diabetic Patients (2016)

In diabetic patients, OAB and diabetic peripheral neuropathy are significantly correlated. These correlations were demonstrated using short, understandable, valid, and reliable disease-specific tests without invasive measures. Using these screening tests, both neurologists and urologists can easily diagnose these complications.
Randomized prospective clinical study comparing induced aberrations with IntraLase and Hansatome flap creation in fellow eyes (2005)

The creation of the LASIK flap alone can modify the eye's optical characteristics in low-order aberrations and HOAs. A significant increase in HOAs was seen in the Hansatome group but not in the IntraLase group. This may have significant clinical implications in wavefront-guided LASIK treatments, which are based on measurements made before flap creation.
Analysis of multistatic configurations for spaceborne SAR interferometry (2003)

Spaceborne bistatic and multistatic SAR configurations are an attractive approach to acquire along-track and cross-track interferograms on a global scale. An efficient realisation of such systems may be achieved by a set of low-cost, passive receivers onboard a constellation of microsatellites which simultaneously record the backscattered signals transmitted by a conventional spaceborne radar. The authors introduce several multistatic SAR configurations suitable for global single-pass interferometry and discuss their advantages and limitations. The achievable interferometric performance is analysed in detail, taking into account thermal noise, block adaptive quantisation, range and azimuth ambiguities, and geometric decorrelation for both surface and random volume scatterers. Based on the estimated interferometric phase errors, the relative height accuracies for three illuminators (PALSAR, ASAR, TerraSAR-X) are derived. The achievable height accuracies are of the order of 2 m for PALSAR and ASAR, and of the order of 1 m for TerraSAR-X. However, it turns out that for vegetated areas, volume decorrelation may become a limiting factor for configurations with large interferometric baselines. These restrictions can be overcome by making the interferometric configuration fully polarimetric and/or increasing the number of available baselines.
Effects of thermally induced birefringence in high-output-power electro-optically Q-switched Nd:YAG lasers and their compensation (1993)

We show that thermally induced birefringence in an electro-optical crystal can play an important role in Q-switched Nd:YAG lasers with a high average power output. A compensation of the thermal effects in both active-element and electro-optical crystals is achieved by employing two identical Pockels cells instead of one, with a pi/2 polarization rotator between them in the so-called ring modulator. Experiments that are carried out show that undesirable thermopolarization effects are essentially eliminated by using this new optical configuration. A detailed description in terms of Jones matrices of the properties of the proposed resonator is also included.

Supported Gold Nanoparticles as Promising Catalysts (2016)

In recent times, gold nanoparticles (AuNPs) either in the form of colloids or as supported nanoparticles are being extensively used as efficient redox catalyst materials. Catalysis particularly using supported gold nanoparticles (AuNPs) has attracted immense research interest due to their unique properties and greater potentiality that is directly related to their particle size. The primary objective of this chapter is to provide comprehensive overview about gold metal nanoparticles (AuNPs) and their application as promising catalysts. This chapter contains six sections in total. Section 1 starts with a general introduction, recent progress, and brief summary of the application of supported AuNPs as promising catalysts for different applications. Section 2 briefs the properties and stability of gold nanoparticles. Section 3 reviews the preparation methods of supported AuNPs for a wide range of catalytic applications. Section 4 describes briefly some of the most commonly reported supported AuNPs for different applications. Section 5 concentrates on our own results related to the application of supported AuNPs in heterogeneous catalysis. In this section, the oxidation of cyclohexane (CH) and benzyl alcohol (BA) to adipic acid (AA), benzaldehyde (BAl), and ammoxidation of 2-methylpyrazine to 2-cyanopyrazine are discussed. Finally, Section 6 describes, main points and outlook are summarized.
