On Hard Adders and Carry Chains in FPGAs (2015)

Abstract—Hardened adder and carry logic is widely used in commercial FPGAs to improve the efficiency of arithmetic functions. There are many design choices and complexities associated with such hardening, including circuit design, FPGA architectural choices, and the CAD flow. There has been very little study, however, on these choices and hence we explore a number of possibilities for hard adder design. We also highlight optimizations during front-end elaboration that help ameliorate the restrictions placed on logic synthesis by hardened arithmetic. We show that hard adders and carry chains, when used for simple adders, increase performance by a factor of four or more, but on larger benchmark designs that contain arithmetic, improve overall performance by roughly 15%. We measure an average area increase of 5 % for architectures with carry chains but believe that better logic synthesis should reduce this penalty. Interestingly, we show that adding dedicated inter-logic-block carry links or fast carry look-ahead hardened adders result in only minor delay improvements for complete designs. I.
Clinical procedure for colon carcinoma tissue sampling directly affects the cancer marker-capacity of VEGF family members (2012)

Sampling-induced hypoxia in resection samples but not in biopsy samples affects the marker-reliability of VEGF family members. Therefore, biopsy samples provide a more accurate report on VEGF family mRNA levels. Furthermore, this limited expression analysis proposes VEGF-A and PlGF as reliable, sampling procedure insensitive mRNA-markers for molecular diagnosis of colon cancer.
Assembly, Stability, and Electrical Properties of Sparse Crystalline Silicon Nanoparticle Networks Applied to Solution-Processed Field-Effect Transistors (2020)

Thin films of crystalline silicon nanoparticles (Si NPs) processed from liquid dispersions of NPs (NP inks) using printing-type deposition methods are currently being intensively investigated for the development of electronic and optoelectronic nanotechnologies. Various (opto)electronic applications have already been demonstrated based on these materials, but so far, devices exhibit modest performance because of relatively low electrical conductivity and charge carrier mobility. In this work, we aim at unveiling the major factors affecting the long-range transport of charges in Si NP thin films. For this, we monitor the electrical properties of thin-film field effect transistors (FETs) as the active channel of the devices is gradually filled with Si NPs. To produce these FET devices featuring stable, sparse Si NP networks within the active channel, we developed a fabrication protocol based on NP deposition by device substrate immersion in a NP ink, made of Si NPs and chlorobenzene, followed by annealing and ultrasonication. We found that both the electrical conductivity and the charge carrier mobility of the FETs increase extremely rapidly as the device channel coverage with NPs increases. Thus, the NP network corresponds effectively to an inhomogeneous blend of conducting and insulating Si NPs, with the most efficient charge percolation paths involving only a fraction of the NPs. We discuss the factors that may lead to this behavior, in view of developing Si NP thin films with competitive charge transport characteristics.
A novel synthesis of imidazoles via the cycloaddition of nitrile ylides to their imidoyl chloride precursors (2001)

Generation of nitrile ylides, 4 and 22, via the base-catalysed 1,3-dehydrochlorination of imidoyl chlorides, 3 and 21, gives the imidazoles, 13, 23 and 24. These imidazoles are formed by the cycloaddition of the nitrile ylides, 4 and 22, to their precursor imidoyl chlorides, 3 and 21, and the observed regiochemistry of this cycloaddition has been rationalised by energy calculations on the frontier molecular orbitals of these reactants using semi-empirical (MOPAC PM3) methods.
Venus, an Astrobiology Target (2021)

&amp;lt;p&amp;gt;The interest in the possibility of life on Venus is driven not just by curiosity about life originating in another Earth-like environment, but because of the possibility that life may be playing a critical role in the planet&amp;amp;#8217;s present, and possibly its past, atmospheric state. The brilliance of Venus in the night sky (as viewed from Earth) is due to its highly reflective cloud cover, about 28 km thick at the equator.&amp;amp;#160; Its spectral albedo is about 90% at wavelengths &amp;gt; 500 nm, but it drops gradually to about 40% around 370 nm before rising slightly at shorter wavelengths.&amp;amp;#160; This albedo drop is due to the presence of several absorbers in the atmosphere and the cloud cover.&amp;amp;#160; A very large fraction of the energy absorbed by Venus is at ultraviolet wavelengths with sulfur dioxide above the clouds contributing to the absorption below 330 nm; however, the identities of the other absorbers remain unknown.&amp;amp;#160; The inability to identify the absorbers that are responsible for determining the radiative energy balance of Venus over the last century is a major impediment to understanding how the planet &amp;amp;#8220;works&amp;amp;#8221;, a major component of NASA&amp;amp;#8217;s efforts in planetary exploration.&amp;amp;#160; Limaye et al. (Astrobiology &amp;lt;strong&amp;gt;18&amp;lt;/strong&amp;gt;, 1181-1198, 2018) presented a hypothesis suggesting that cloud-based microbial life could be contributors to the spectral signatures of Venus&amp;amp;#8217; clouds, building upon previous suggestions of the possibility of life in the clouds of Venus.&amp;lt;/p&amp;gt;&amp;lt;p&amp;gt;Four interconnected themes for the exploration of Venus as an astrobiology target are: &amp;amp;#8211; (i) investigations focused on the likelihood that liquid water existed on the surface in the past leading to the potential for the origin and evolution of life, (ii) investigations into the potential for habitable zones within Venus&amp;amp;#8217; clouds and Venus-like atmospheres, (iii) theoretical investigations into how active aerobiology may impact the radiative energy balance of Venus&amp;amp;#8217; clouds and Venus-like atmospheres, and (iv) application of these investigative themes towards better understanding the atmospheric dynamics and habitability of exoplanets. These themes can serve as a basis for proposed Venus Astrobiology Objectives and suggestions for measurements for future missions, as per the goals and objectives developed by the Venus Exploration Analysis Group (VEXAG), which is sponsored by NASA to plan for the future exploration of Venus.&amp;amp;#160;&amp;amp;#160;&amp;lt;/p&amp;gt;&amp;lt;p&amp;gt;A Venus Collection to be published in Astrobiology journal in 2021 will include papers from the&amp;amp;#160; &amp;amp;#8220;Habitability of the Venus Cloud Layer&amp;amp;#8221;, Moscow (October 2019) workshop.&amp;amp;#160;&amp;lt;/p&amp;gt;
Ultrafast Hybrid Plasmonics: New Routes to Nanoscale Imaging and Energy Propagation (2009)

Practical Experience with PMU System Testing and Calibration Requirements (2008)

New data acquisition technologies, such as phasor measurement units (PMU), have been implemented in recent years to operate the power system with more reliability and control by improving the protection schemes like line differential protection or damping the inter-area oscillations. The present standard IEEE C37.118 only provides general information about the testing conditions and requirements, without giving any specifics.. To create the PMU data function for the applications and thereby make the power system more reliable, the appropriate PMU test standards have to be developed and disseminated. Future testing methods should ensure that units from different manufacturers are tested identically and function properly under different repeatable test scenarios and test stand set up conditions. This paper presents experiences from tests of PMU accuracy and calibration conducted in Europe and the USA, which will facilitate the development of future standards. The test stand itself and the test results from the various PMU manufactures are presented, compared and discussed in this paper, taking into account the standardization issues.
Proteinase‐activated receptor‐1 (PAR‐1) activation contracts the isolated human renal artery in vitro (2003)

1. The in vitro motor function of protease-activated recepter-1 (PAR-1), PAR-2 and PAR-4 and the presence by immunohistochemistry of PAR-1 in the human renal artery have been investigated. 2. Thrombin and the human PAR-1 (SFLLRN-NH(2)) activating peptide, but not the PAR-1 reverse peptide (NRLLFS-NH(2)), contracted both endothelial-intact and endothelial-denuded human renal artery strips, whereas no relaxation was observed either in strips non-precontracted or precontracted with phenylephrine. Maximum contraction by thrombin or SFLLRN-NH(2) was about 60% of phenylephrine. However, thrombin was approximately 1000-fold more potent than SFLLRN-NH(2). 3. PAR-1 desensitisation, using repeated applications of SFLLRN-NH(2), almost completely blocked the response to thrombin. The contractile effect produced by thrombin and SFLLRN-NH(2) was not affected by nitric oxide synthase inhibition, but was significantly reduced by cyclooxygenase blockade. 4. Trypsin, the PAR-2 (SLIGKV-NH(2) and SLIGRL-NH(2)) and PAR-4 (GYPGQV-NH(2) and AYPGKF-NH(2)) activating peptides did not produce any significant contraction or relaxation. 5. In agreement with the motor function data immunohistochemistry showed specific staining patterns for PAR-1 in the human renal artery. 6. Combined, these studies would suggest a possible role for PAR-1 in renal vascular homeostasis.

Conversion Schemes for Unlinkable Signatures That Include Revocable Unlinkability (2006)

This paper introduces the concept of for unlinkable anonymous signatures and proposes a generalized scheme that modifies the signatures to include revocable unlinkability. Revocable unlinkability provides a condition in which multiple messages signed using an unlinkable anonymous signature are unlinkable for anyone except the unlinkability revocation manager. Noteworthy is that the identifier of the signer is kept secret from the manager. In addition, examples are presented in which the proposed scheme is applied to existing group/ring signatures. The proposed scheme employs a verifiable MIX-net to shuffle the identifiers of all potential signers, thus giving it the potential for wide application to unlinkable anonymous signatures.
Discovery of Antitumor Indolocarbazoles: Rebeccamycin, NSC 655649, and Fluoroindolocarbazoles (2002)

A fermentation directed product search for potential anticancer drugs conducted by Bristol-Myers in the 1970s and early 1980s resulted in the identification of a novel indolocarbazole (IC) rebeccamycin (RBM) as a potential drug development candidate. Subsequently, an analog program designed to impart distal site in vivo antitumor activity resulted in the discovery of diethylaminoethyl analog of RBM (DEAE-RBM), which is presently undergoing clinical evaluation as NSC 655649 and BMY-27557. Strong DNA intercalation is the primary mechanism of action of DEAE-RBM resulting in the potent catalytic inhibition of both topoisomerases I and II. Precursor feeding fermentation experiments with fluorine-substituted tryptophans yielded novel fluoroindolocarbazoles (FICs). These FICs were identified as targeting topoisomerase (topo) I in a mechanism-based screen and their action on topo I was confirmed by production of topo I-mediated single-strand breaks in DNA at sites essentially identical to those induced by camptothecin. Topo I dependent cytotoxicity was demonstrated for specific FICs using a P388 and camptothecin-resistant P388/CPT45 pair of cell lines, the latter expresses little or no functional topo I. For example, topo I selectivity was greatest with 3,9-difluoro substituted FIC and was least significant and least cytotoxic with 4,8-difluoro substituted FIC. The review focuses on the discovery of the rebeccamycin class of compounds and their structure-activity relationships leading to the development of the clinical candidate BMY-27557 (NSC 655649), as well as the lead identification of the fluoroindolocarbazole class of compounds.
Accessible Field Enhancements with Plasmonic Nanoparticles on Nanopedestals for Nanospectroscopy (2011)

We show that plasmonic nanoparticle arrays on dielectric nanopedestals support easily accessible hot spots for target molecules, which is crucial for increasing signals in biosensors and vibrational nanospectroscopy.
Laser Chemical Analysis (1984)

Selected applications of laser methods to analytical problems are reviewed. Examples are chosen from multiphoton ionization and laser fluorescence analysis. Although efforts to carry out elemental analysis with laser techniques are probably the most advanced, studies suggest that the analysis of molecular species is also quite promising, particularly in regard to interfacing laser fluorimetric detection with high-performance liquid chromatography. Recent experiments indicate that analysts can expect to attain in a number of cases the ultimate limit of single-atom or single-molecule detection with laser-based methods.
Quick Torsion Torque Control Based on Model Error Compensator and Disturbance Observer with Torsion Torque Sensor (2021)

Conventionally, I-P-I-P torsion torque control has been proposed for realizing the load-side acceleration control that is a robust motion control for the flexible joint manipulator. However, conventional torsion torque control is designed as a 4th-order delay system and it is difficult to improve the control bandwidth. For this, reducing control-system-order is required. This paper proposes a quick torsion torque control based on a force and position sensors integrated disturbance observer (FPIDO) and a model error compensator (MEC) for improving the performance of human interaction in the flexible joint manipulator. The proposed approach that combines the FPIDO and MEC is capable of control the design of the torsion torque control at the 2 <sup xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">nd</sup> -order delay system. The proposed approach is verified through numerical simulation and experimental results.
Optical Cross-Links for Microsatellite Fleets (2002)

In a study for the European Space Agency we explored architectures and terminal configurations for optical cross-links within fleets of microsatellites and assessed the applicability of available technologies. As an example we cover a scenario where four microsatellites form a planar, square formation of 1 km side length, where the data rate is 100 kbit/s, and where an active doublepass lidar between each of the satellites provides a ranging accuracy of better than 10 m. The terminals operate at a wavelength of 980 nm, the receive apertures have a diameter of 5 mm, and the size, mass, and prime power requirement of one terminal is estimated to be 60x80x70 mm 3 , 900 g, and 5 W, respectively.
Faulty robot rescue by multi-robot cooperation (2013)

SUMMARY This paper presents a multi-agent behavior to cooperatively rescue a faulty robot using a sound signal. In a robot team, the faulty robot should be immediately recalled since it may seriously obstruct other robots, or collected matters in the faulty robot may be lost. For the rescue mission, we first developed a sound localization method, which estimates the sound source from a faulty robot by using multiple microphone sensors. Next, since a single robot cannot recall the faulty robot, the robots organized a heterogeneous rescue team by themselves with pusher, puller, and supervisor. This self-organized team succeeded in moving the faulty robot to a safe zone without help from any global positioning systems. Finally, our results demonstrate that a faulty robot among multi-agent robots can be immediately rescued with the cooperation of its neighboring robots and interactive communication between the faulty robot and the rescue robots. Experiments are presented to test the validity and practicality of the proposed approach.

Wave anisotropy of shear viscosity and elasticity (2014)

The paper presents the theory of shear wave propagation in a “soft solid” material possessing anisotropy of elastic and dissipative properties. The theory is developed mainly for understanding the nature of the low-frequency acoustic characteristics of skeletal muscles, which carry important diagnostic information on the functional state of muscles and their pathologies. It is shown that the shear elasticity of muscles is determined by two independent moduli. The dissipative properties are determined by the fourth-rank viscosity tensor, which also has two independent components. The propagation velocity and attenuation of shear waves in muscle depend on the relative orientation of three vectors: the wave vector, the polarization vector, and the direction of muscle fiber. For one of the many experiments where attention was distinctly focused on the vector character of the wave process, it was possible to make a comparison with the theory, estimate the elasticity moduli, and obtain agreement with the angular dependence of the wave propagation velocity predicted by the theory.
Stimulation of Dendritic Cells via CD40 Enhances Immune Responses toMycobacterium tuberculosisInfection (2001)

The resolution of pulmonary tuberculosis (TB) critically depends on the development of the Th1 type of immune responses, as exemplified by the exacerbation of TB in IL-12-deficient mice. Therefore, vaccination strategies optimizing IL-12 production by antigen-presenting cells (APC) in response to mycobacteria may have enhanced protective efficacy. Since dendritic cells (DC) are the critical APC for activation of CD4+ and CD8+ T cells, we examined whether stimulation of Mycobacterium bovis bacillus Calmette Guérin (BCG)-infected DC via CD40 increased their ability to generate Th1-oriented cellular immune responses. Incubation of DC with an agonistic anti-CD40 antibody activated CD40 signaling in DC, as shown by increased expression of major histocompatibility complex class II and costimulatory molecules, mRNA production for proinflammatory cytokines and interleukin 12 (IL-12) p40. This activation pattern was maintained when DC were stimulated with anti-CD40 antibody and infected with BCG. Importantly, CD40-stimulated BCG-infected DC displayed increased capacity to release bioactive IL-12 and to activate gamma interferon (IFN-gamma) producing T cells in vitro. Moreover, when C57BL/6 mice were immunized with these DC and challenged with aerosol Mycobacterium tuberculosis, increased levels of mRNA for IL-12 p40, IL-18, and IFN-gamma were present in the draining mediastinal lymph nodes. However, the mycobacterial burden in the lungs was not reduced compared to that in mice immunized with BCG-infected non-CD40-stimulated DC. Therefore, although the manipulation of DC via CD40 is effective for enhancing immune responses to mycobacteria in vivo, additional strategies are required to increase protection against virulent M. tuberculosis infection.
Privacy policy enforcement in enterprises with identity management solutions (2006)

People are usually asked by enterprises and other organizations to disclose their personal information to access web services and engage in business interactions. Enterprises need this information to enable their business processes. This is unlikely to change, at least in the foreseeable future. When collecting personal data, enterprises must satisfy privacy laws and policies along with addressing people's expectations on how their data should be handled. Currently much is done by means of manual processes, in particular in terms of privacy enforcement: these processes are prone to mistakes and hard to comply with. Automation can help enterprises to deal with these privacy management issues, in particular the enforcement of privacy policies on collected personal data. Enterprises have already been investing in identity management solutions: they require that approaches to automate privacy management should keep into account and leverage these solutions. This paper discusses our research and development work to automate the enforcement of privacy policies in enterprises. Our model of privacy policy enforcement is introduced along with the technical details of a related prototype, integrated (as a proof of concept) with HP Select Access, a state-of-the-art identity management solution. This technology is currently under productisation. We discuss our current results and next steps.
Essential Oil Quality and Yield with Respect to Harvest Index inTagetes minutaCultivated in Sub Tropical Plains of North India (2006)

Abstract Planned studies were carried out to determine the most appropriate stage of economic harvest in Tagetes minuta by examining dry matter partitioning, essential oil yield and quality of oil at different growth stages grown in Lucknow conditions at the Central Institute of Medicinal and Aromatic Plants, Lucknow, India, during winter season 2002–2003. The maximum essential oil yield (1.01 g/plant and 56.1 kg/ha) was obtained upon harvesting at post fowering stage (seed setting stage). Advantage in essential oil yield at this stage was 130%, 34.5% and 36.5% yield enhancement over pre-flowering, 50% and 100% flowering stages, respectively. Flowers and leaves contained the maximum essential oil 2.14% and 1.89% (dry weight basis), respectively. Relative contribution of leaf, flower and stem to essential oil production was 40.7%, 37.8% and 21.5%, respectively. In the oil quality analysis, dihydrotagetone (77.1%) was the predominant component in oil from the leaves while (Z)-β-ocimene, limonene and (Z)-tagetone were the major constituents in the flower oil. The study suggests that T. minuta should be harvested at the post-flowering stage for realizing maximum essential oil yield and its desirable major chemical constituents. The study also differentiated the quality of leaf and fower oil for chemical constituents.
