A new representation for collision avoidance and detection (2003)

By combining the simplicity of the sphere and the power of the motion of hierarchy of detail, a novel model is proposed with applications to collision avoidance and detection in 3D. The model is based on a double spherical representation for solid bodies. First, each element making up the robot and the obstacles is approximated by a set of exterior spheres which are automatically defined. Second, another set composed of interior spheres is generated. These representations define a hierarchy, since they can be redefined as many times as necessary; starting with two spheres per element, the approximation may be improved until it contains hundreds of spheres. Moreover, they converge to a zero-error representation. The proposed models leads to a simple treatment for the problem of collision detection, and it is further applied to collision-free path planning for manipulators in 3D.< <ETX xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">></ETX>
Sucrose biosynthesis in a prokaryotic organism: Presence of two sucrose-phosphate synthases in <i>Anabaena</i> with remarkable differences compared with the plant enzymes (1996)

Biosynthesis of sucrose-6-P catalyzed by sucrose-phosphate synthase (SPS), and the presence of sucrose-phosphate phosphatase (SPP) leading to the formation of sucrose, have both been ascertained in a prokaryotic organism: Anabaena 7119, a filamentous heterocystic cyanobacterium. Two SPS activities (SPS-I and SPS-II) were isolated by ion-exchange chromatography and partially purified. Four remarkable differences between SPSs from Anabaena and those from higher plants were shown: substrate specificity, effect of divalent cations, native molecular mass, and oligomeric composition. Both SPS-I and SPS-II accept Fru-6-P (K(m) for SPS-I = 0.8 +/- 0.1 mM; K(m) for SPS-II = 0.7 +/- 0.1 mM) and UDP-Glc as substrates (K(m) for SPS-I = 1.3 +/- 0.4 mM; K(m) for SPS-II = 4.6 +/- 0.4 mM), but unlike higher plant enzymes, they are not specific for UDP-Glc. GDP-Glc and TDP-Glc are also SPS-I substrates (K(m) for GDP-Glc = 1.2 +/- 0.2 mM and K(m) for TDP-Glc = 4.0 +/- 0.4 mM), and ADP-Glc is used by SPS-II (K(m) for ADP-Glc = 5.7 +/- 0.7 mM). SPS-I has an absolute dependence toward divalent metal ions (Mg2+ or Mn2+) for catalytic activity, not found in plants. A strikingly smaller native molecular mass (between 45 and 47 kDa) was determined by gel filtration for both SPSs, which, when submitted to SDS/PAGE, showed a monomeric composition. Cyanobacteria are, as far as the authors know, the most primitive organisms that are able to biosynthesize sucrose as higher plants do.
Specificity and regulation of the<i>mutator</i>transposable element system in maize (1993)

Abstract The Mutator transposable element system is exceptional in many of its basic attributes. The high frequency and low specificity of mutant induction are both unusual and useful characteristics of the Mutator system. Other basic features are at least equally fascinating: the existence of multiple Mu element subfamilies with apparently unrelated internal sequences; the lack of correlation between Mu element transposition and excision; the complex inheritance of Mutator activity; the tight developmental regulation of Afufaror‐conditioned events; and the coordinated processes of element modification/inactivation, to name a few. Molecular and genetic studies over the last 10 years have begun to explain many of these interesting properties and have uncovered new mysteries of Mutator biology. Both positive and negative regulators of the system have been identified and characterized to varying degrees. Insertion specificity has been observed at several levels. Recent accomplishments include the isolation of an autonomous Mu element and the discovery of maize lines with altered developmental regulation of Mutator‐derived mutability. This review defines the Mutator system, describes the status of current experimentation in the Mutator field, proposes models that may explain some aspects of Mutator behavior, and details future studies that will help elucidate the nature of the Mutator phenomenon.

In How to Create a Mind, he presents a provocative exploration of the most important project in the human-machine civilization: reverse-engineering the brain to understand precisely how it functions and using that knowledge to create even more intelligent machines. Kurzweil discusses how the brain works, how the mind emerges, brain-computer interfaces, and the implications of vastly increasing the powers of our intelligence to address the worlds problems. Certain to be one of the most widely discussed and debated science books of the year, How to Create a Mind is sure to take its place alongside Kurzweils previous classics.
A semantic network representation of personal construct systems (1992)

A method is presented for transforming and combining heuristic knowledge gathered from multiple domain experts into a common semantic network representation. Domain expert knowledge is gathered with an interviewing tool based on personal construct theory. The problem of expressing and using a large body of knowledge is fundamental to artificial intelligence and its application to knowledge-based or expert systems. The semantic network is a powerful, general representation that has been used as a tool for the definition of other knowledge representations. Combining multiple approaches to a domain of knowledge may reinforce mutual experiences, information, facts, and heuristics, yet still retain unique, specialist knowledge gained from different experiences. An example application of the algorithm is presented in two separate expert domains.< <ETX xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">></ETX>

Impact wear of thin NiCo film on magnetic recording disk (1981)

The magnetic recording depends critically on the integrity of the interface which consists of the thin magnetic film, the slider surface and the dynamic airbearing. An experimental technique is presented to show that it can be used to determine the threshold impact intensity to cause measurable wear on the thin metal film recording disk, the relationship between the impact wear and the readback signal, the slider flying dynamics, and to detect the impact transient elasto-plastic deformation and wear.
Ink Jet Printing for Functional Ceramic Coatings (2011)

The interest in functional ceramic coatings based on low cost and flexible manufacturing has been heightened by the effectiveness shown by chemical solution deposition of metal-organic salts, usually based on the use of spin coating, dip coating, or slot die coating techniques prior to thermal treatment to achieve decomposition of the starting salts. The possibility of implementing effective drop on demand systems in the manufacturing process allows a more efficient way to apply the precursor solution homogeneously onto the substrate, thus, enabling control of thickness of the ceramic coating, by controlling the drop size and the pitch of the printing pattern, among other manufacturing advantages such as control of solvent evaporation. In the present work, the authors report on their experiments concerning ink jet coating of functional complex ceramics for La0.7Sr0.3MnO3 and YBa2Cu3O7–x layers and patterns over single crystal and polycrystalline substrates using an electromagnetic system and a single nozzle piezoelectric dispenser. Characterization of rheological properties of the developed ink and of the resulting coating by optical microscopy, x-ray diffraction, scanning electron microscopy, and magnetic behavior are reported.
Luciferase-based protein denaturation assay for quantification of radiofrequency field-induced targeted hyperthermia: Developing an intracellular thermometer (2012)

Cancer cells when exposed to an external RF field exhibit dose-dependent protein denaturation. Luciferase denaturation assay can be used to quantify thermal dose delivered after RF exposures to cancer cells with and without nanoparticles.
Numerical studies of transport and spin-orbit exchange in InAs nanowires (2013)

High spin-orbit coupling and low effective mass of electrons in InAs nanowires makes it an attractive material for studying quantum physics in mesoscopic and nanoscale quantum devices. We first study the transport properties of FET devices made of InAs nanowires of diameter in the range of 35-70 nm. The temperature dependence of electron mobility in InAs nanowires from 10-200 K exhibits a positive slope below approximately 0 K, then turns over to a negative slope at higher temperatures. This is explained by Coulomb scattering from the surface donor like states that give rise to a subsurface accumulation layer and the thermal activation of these surface donors. The scattering rates are calculated using a momentum relaxation time approximation. The transition probabilities between the self-consistent Poisson-Schrodinger states of a 50 nm diameter nanowire are calculated\nusing Fermi's golden rule. The results clarify the dominant scattering mechanism in InAs\nnanowires and signify the need for surface passivation to obtain high mobility devices.\nIn a second study, we model a gate defined double quantum dot in the nanowire with\nhigh spin-orbit coupling in order to determine the precise gate voltage dependence of the exchange Hamiltonian. This modelling is critical for designing two-qubit quantum logic operations in the nanowire double dot architecture. A quantum double well structure is simulated based on the realistic potential created by a set of fine local electrostatic gates in the presence of nanowire surface accumulation layer. An effective spin Hamiltonian is\nderived for a pair of interacting electrons localized in the double dot system in the presence\nof a strong spin-orbit coupling. The accuracy of the effective Hamiltonian is established by\na strong agreement obtained between the dynamics generated by the effective Hamiltonian\nwith those obtained by a numerically exact solution of the time-dependent Schrodinger\nequation. The parametric dependences of the effective exchange Hamiltonian on external\nmagnetic field, barrier gate voltage, and spin-orbit field is determined. This opens the door\nto designing optimal pulses for high fidelity quantum gates in real InAs nanowire devices.
Coronary heart disease detection from voice analysis (2016)

Coronary Heart Disease (CHD) is one of the major causes of death now-a-days. Due to increased stress level and many other reasons the heart disease are common in human. The heart problems affect the larynx and breathing and consequently the quality of speech. The current work is aimed at understanding the variation of voice parameter in the CHD patients. For processing the voice signal CSL (Computerized Speech Lab) model 4500 is used, it also contains MDVP (Multi Dimensional Voice Program), that analyzes and displays up to 22 voice parameters from a single voice analysis. The CHD group of 80 persons are compared by the group of 80 normal persons (named as control group) containing both male and female. The study shows the variations in Spectrogram, Long Term Average Spectrum (LTAS) and other voice parameters like jitter, shimmer, APQ of CHD group in comparison with the control group.
Video game watermarking (2013)

The publishers of video games suffer from illegal piracy and information leakage caused by end-consumers, "release groups" or insiders shortly after or even before the official release of a new video game. Mechanisms to prevent or at least postpone this illegal redistribution are DRM or copy protection mechanisms. However, these mechanisms are very unpopular, because they restrict the customers in playing the game and demand a high administration effort from the developers and/or distributors. Even worse, most copy protection mechanisms have proven to be insecure as "patches" for circumvention usually are available quickly and easy to get. To satisfy the challenges of security and usability, this work introduces the idea of using digital watermarking to protect all available and suitable media types and software binaries contained in a video game. A three-layered watermarking deployment approach along the production chain is proposed to detect leakage in the release phase as well as during the development process of a boxed video game. The proposed approach features both copyright watermarking and collusion secure fingerprints embedded as transaction watermark messages in components of video games. We discuss the corresponding new challenges and opportunities. In addition, a prototype watermarking algorithm is presented to demonstrate the adaption necessity of classical image watermarking when applied to video games to satisfy the requirements for transparency, security as well as performance. The watermark capacity is significantly increased while inter-media and inter-file embedding is enabled and the associated synchronization challenge is solved by robust hashes.
Molecular Pathways: Overcoming Radiation Resistance by Targeting DNA Damage Response Pathways (2015)

DNA double-strand breaks are the critical lesions responsible for the majority of ionizing radiation-induced cell killing. Thus, the ability of tumor cells to elicit a DNA damage response following radiation, via activation of DNA repair and cell-cycle checkpoints, promotes radiation resistance and tumor cell survival. Consequently, agents that target these DNA damage response pathways are being developed to overcome radiation resistance. Overall, these agents are effective radiosensitizers; however, their mechanisms of tumor cell selectivity are not fully elucidated. In this review, we focus on the crucial radiation-induced DNA damage responses as well as clinical and translational advances with agents designed to inhibit these responses. Importantly, we describe how synthetic lethality can provide tumor cell-selective radiosensitization by these agents and expand the therapeutic window for DNA damage response-targeted agents used in combination with radiotherapy.
Hypoxia-Inducible Factors HIF-1α and HIF-2α Expression in Bladder Cancer and Their Associations with Other Angiogenesis-Related Proteins (2006)

Hypoxia-inducible factors (HIF-1alpha and HIF-2alpha) are closely related protein complexes that activate transcription of target genes in response to hypoxia. The immunohistochemical expression of these two proteins was investigated in 144 bladder cancer tissue samples and correlated with standard clinicopathological features, in order to elucidate their prognostic significance. We also evaluated their possible associations with other angiogenesis related markers such as microvessel density (MVD), vascular endothelial growth factor, thymidine phosphorylase, tenascin, fibronectin, p53 and bcl-2 to further clarify their implication in tumor stroma vascularization. Nuclear HIF-1alpha expression in tumor cells was detected in 57.1% of the cases. A trend of correlation of this expression with poorly differentiated tumors was observed. In addition, HIF-1alpha expression was positively correlated with stromal cells thymidine phosphorylase expression. Tumors that were progressed in muscle-infiltrating disease showed a higher HIF-1alpha expression. A higher HIF-1alpha expression was also observed in tumors with an in situ component. In tumor cells, low HIF-2alpha expression was observed in 6.3%, moderate in 31.9% and high in 61.8% of the cases. A trend of correlation of this expression with MVD was observed. In addition, HIF-2alpha expression was positively correlated with thymidine phosphorylase and fibronectin expression. A lower HIF-2alpha expression was detected in tumors that recurred earlier in univariate methods of analysis. HIF-2alpha was expressed in tumor stroma associated cells in 53.5% of specimens and was correlated with advance tumor stage, thymidine phosphorylase and tenascin expression. There was no statistically significant difference in the expression of both HIF-1alpha and HIF-2alpha between primary and recurrent tumors. In multivariate analysis including T stage, T grade, multifocality and T size, both HIF-1alpha and HIF-2alpha expression were not considered dependent in the prediction of recurrence or progression. In conclusion, the results of the present study indicate that HIF-1alpha and HIF-2alpha expression may help to predict recurrence or progression to muscle invasive disease but not as independent prognostic factors. In addition, the expression of HIF-1alpha and HIF-2alpha, appear to play a role in bladder cancer, vascularization possibly and in cooperation with other angiogenic factors.
Definability and decision problems in arithmetic (1949)

In this paper, we are concerned with the arithmetical definability of certain notions of integers and rationals in terms of other notions. The results derived will be applied to obtain a negative solution of corresponding decision problems. In Section 1, we show that addition of positive integers can be defined arithmetically in terms of multiplication and the unary operation of successor S (where Sa = a + 1). Also, it is shown that both addition and multiplication can be defined arithmetically in terms of successor and the relation of divisibility | (where x|y means x divides y ).

A Fast-Response True-Mass-Rate Flowmeter (1953)

Abstract A flowmeter capable of measuring directly the true rate of mass flow would have many industrial applications and would eliminate many of the shortcomings of instruments now available for flow measurements. A description and diagrams are presented of a new type of mass-rate flowmeter with a long range, a linear scale, and a very fast response.
Multicasting Mesh AER: A Scalable Assembly Approach for Reconfigurable Neuromorphic Structured AER Systems. Application to ConvNets (2012)

This paper presents a modular, scalable approach to assembling hierarchically structured neuromorphic Address Event Representation (AER) systems. The method consists of arranging modules in a 2D mesh, each communicating bidirectionally with all four neighbors. Address events include a module label. Each module includes an AER router which decides how to route address events. Two routing approaches have been proposed, analyzed and tested, using either destination or source module labels. Our analyses reveal that depending on traffic conditions and network topologies either one or the other approach may result in better performance. Experimental results are given after testing the approach using high-end Virtex-6 FPGAs. The approach is proposed for both single and multiple FPGAs, in which case a special bidirectional parallel-serial AER link with flow control is exploited, using the FPGA Rocket-I/O interfaces. Extensive test results are provided exploiting convolution modules of 64 × 64 pixels with kernels with sizes up to 11 × 11, which process real sensory data from a Dynamic Vision Sensor (DVS) retina. One single Virtex-6 FPGA can hold up to 64 of these convolution modules, which is equivalent to a neural network with 262 × 10(3) neurons and almost 32 million synapses.
Electrochemical studies of copper in N-N, dimethylformamide in the presence of water, ethanol and acetic acid as additives (2000)

The electrochemical behaviour of copper has been investigated in N-N, dimethylformamide in the presence of water, ethanol and/or acetic acid as contaminants, by a potentiodynamic method. The electrooxidation of the electrode started at around -0.20V(SCE). Two oxidation peaks were observed and attributed to Cu -> Cu(I) and Cu -> Cu(II) processes. The reduction of the oxide was observed during the cathodic potential sweep. The presence of water and ethanol increased the anodic current while in the presence of acetic acid this process was inhibited. The incidence of polychromatic light on the electrode surface decreased the anodic current. It was suggested that the light affects the interaction between the adsorbed water and the surface of the metal.
Cost analysis of three low-temperature sterilization systems at Saint Barnabas Medical Center. (1994)

To avoid the heavily increasing costs of ethylene oxide, and with the imminent demise of 88/12 EtO at the same time that heat-sensitive endoscope use was on the rise, Saint Barnabas Medical Center in Livingston, NJ was urgently interested in choosing among low-temperature sterilization alternatives currently available. They decided to compare the costs of 100% EtO with the 88/12 system and a new, low-temperature hydrogen peroxide gas plasma system (HPGP) called STERRAD. The HPGP system proved to be less expensive overall than either EtO system due to quicker total cycle times, lower utility use and virtually no regulatory compliance issues. The hospital was also satisfied that the system effectively sterilized the items on which it was used.
