Dense 3D Reconstruction from Severely Blurred Images Using a Single Moving Camera (2013)

Motion blur frequently occurs in dense 3D reconstruction using a single moving camera, and it degrades the quality of the 3D reconstruction. To handle motion blur caused by rapid camera shakes, we propose a blur-aware depth reconstruction method, which utilizes a pixel correspondence that is obtained by considering the effect of motion blur. Motion blur is dependent on 3D geometry, thus parameter zing blurred appearance of images with scene depth given camera motion is possible and a depth map can be accurately estimated from the blur-considered pixel correspondence. The estimated depth is then converted into pixel-wise blur kernels, and non-uniform motion blur is easily removed with low computational cost. The obtained blur kernel is depth-dependent, thus it effectively addresses scene-depth variation, which is a challenging problem in conventional non-uniform deblurring methods.
Home multimedia integration system using UPnP and Service Convergence Gateway engine (2008)

Recently, due to the rapid development of IT technology and the penetration of internet through super high-speed internet network, lots of network-enabled multimedia devices are spread in the home network. However, there are integration and management problems because of their incompatibility. In this paper, we propose home multimedia integration system that integrates multimedia devices and services in the home network using UPnP and Service Convergence Gateway (SCG) engine. The SCG engine is a gateway engine for service convergence among devices. This home multimedia integration system pursued the integration of services of home multimedia devices and its contents, and tried to enable their management and control easily. Using this system, we can use any media contents that contained in any multimedia devices, regardless of where media contents are physically stored. Also, this system provides two methods to expand the system to the outside of home network. One is allowance of connections from the outside of home network, and the other is to make a external multimedia contents service information storage to integrate multimedia contents services which are provided by outside of home network. In addition, we evaluate this system by implementing core parts of the system.
PEDESTRIAN CROSSING BEHAVIOUR ANALYSIS AT INTERSECTIONS (2014)

Pedestrian crossing behavior is analyzed for the provision of proper pedestrian facilities at desired locations, as well as to improve their safety while crossing the road. This paper presents the analysis of pedestrian crossing behavior from a study conducted at Roorkee city (Uttarakhand state in India). The effect of pedestrian characteristics like age, gender and that of carrying baggage and luggage as well as their crossing patterns were examined on pedestrian flow characteristics like crossing speed and waiting time. Pedestrian safety was also analyzed with respect to safety margins and gaps accepted by pedestrian in traffic stream. Crossing patterns were observed for different age group and gender.
Response to Phosphate Deprivation in <i>Brassica nigra</i> Suspension Cells (1990)

Suspension cells of Brassica nigra responded to Pi deprivation by increasing their potential for Pi influx and by raising the active levels of intracellular, cell surface, and secreted acid phosphatases. These responses, however, were temporally distinct. Phosphate influx capacity increased 15-fold in parallel to a 10-fold decrease in endogenous Pi during 7 days of culture in basal growth medium. In contrast, intracellular and cell surface phosphatase activities changed only after alterations in cellular phosphorus status had been in place for a number of days. Even in nutrient sufficient cells the secretion of phosphatase remained relatively high as did the activities of the other phosphatases. The cell surface acid phosphatase had a K(m) of approximately 10 times that of the influx process and molybdate was a much stronger inhibitor of this phosphatase activity. From these results it appears that Pi absorption and the production or activation of phosphatases are regulated in a distinct manner. In addition, Pi uptake into Brassica nigra cells does not appear to directly involve the cell surface phosphatase under Pi-deficient conditions.
Use of polymer/ionic liquid plasticizers as gel electrolytes in electrochromic devices (2008)

The dual polymer configuration is commonly used when constructing electrochromic devices (ECDs) due to the expected electrochemical stability and enhanced optical properties. In this configuration, two different polymers are used which are optically complementary. Herein we report the construction and characterization of dual-type ECDs using poly(3, 4-ethylenedioxythiophene) (PEDOT) and poly[3, 6-bis(2-(3, 4-ethylenedioxy)thienyl)-N-methylcarbazole] (PBEDOT-NMCz) as the two complementary electrochromic polymers for the device. A variety of gel electrolyte solutions were prepared and evaluated for these devices. The use of ionic liquids within these gels imparted interesting properties, including long lifetimes, and thermal stability of devices. Switching speeds for the various devices, as well as optical contrasts, were also obtained for the gel electrolytes containing different amounts of ionic liquid as plasticizer.
[Juices in therapeutic-prophylactic nutrition]. (1999)

The main aspects of using juices with therapeutic and prophylactic purposes are demonstrated. Multifactorial influence of vegetable and fruit juices on the organism, primarily depends on their chemical composition. The necessity of their differentiated use basing not only nosological unity, but also on the degree of functional and metabolic disorders taking place in certain pathology is emphasized. Different juices are characterized in respect to the effect on different functional systems of the body. The new line in research is the ability of juices to change pharmacokinetics and pharmacodynamics of medicines given with juices. The importance of juices as a necessary element of therapeutic and healthy nutrition in case of their using in adequate amounts is emphasized.
Optogenetic elevation of endogenous glucocorticoid level in larval zebrafish (2013)

The stress response is a suite of physiological and behavioral processes that help to maintain or reestablish homeostasis. Central to the stress response is the hypothalamic-pituitary-adrenal (HPA) axis, as it releases crucial hormones in response to stress. Glucocorticoids (GCs) are the final effector hormones of the HPA axis, and exert a variety of actions under both basal and stress conditions. Despite their far-reaching importance for health, specific GC effects have been difficult to pin-down due to a lack of methods for selectively manipulating endogenous GC levels. Hence, in order to study stress-induced GC effects, we developed a novel optogenetic approach to selectively manipulate the rise of GCs triggered by stress. Using this approach, we could induce both transient hypercortisolic states and persistent forms of hypercortisolaemia in freely behaving larval zebrafish. Our results also established that transient hypercortisolism leads to enhanced locomotion shortly after stressor exposure. Altogether, we present a highly specific method for manipulating the gain of the stress axis with high temporal accuracy, altering endocrine and behavioral responses to stress as well as basal GC levels. Our study offers a powerful tool for the analysis of rapid (non-genomic) and delayed (genomic) GC effects on brain function and behavior, feedbacks within the stress axis and developmental programming by GCs.
Study, design and construction of a 3D printer implemented through a delta robot (2015)

This article describes the design and implementation of a 3D printer prototype based on a delta parallel robot, which decreases printing time without losing quality in the final product. In addition, the free software, Repertier, was used for programming and GUI. For height calibration of printer dock, an automatic leveling system was develop through an inductive sensor in order to avoid manual handling.
A survey and taxonomy of on-chip monitoring of multicore systems-on-chip (2013)

Billion transistor systems-on-chip increasingly require dynamic management of their hardware components and careful coordination of the tasks that they carry out. Diverse real-time monitoring functions assist towards this objective through the collection of important system metrics, such as throughput of processing elements, communication latency, or resource utilization for each application. The online evaluation of these metrics can result in localized or global decisions that attempt to improve aspects of system behavior, system performance, quality-of-service, power and thermal effects under nominal conditions. This work provides a comprehensive categorization of monitoring approaches used in multiprocessor SoCs. As adaptive systems are encountered in many disciplines, it is imperative to present the prominent research efforts in developing online monitoring methods. To this end we offer a taxonomy that groups strongly related techniques that designers increasingly use to produce more efficient and adaptive chips. The provided classification helps to understand and compare architectural mechanisms that can be used in systems, while one can envisage the innovations required to build real adaptive and intelligent systems-on-chip.
Lane boundary and curb estimation with lateral uncertainties (2009)

This paper describes an algorithm for estimating lane boundaries and curbs from a moving vehicle using noisy observations and a probabilistic model of curvature. The primary contribution of this paper is a curve model we call lateral uncertainty, which describes the uncertainty of a curve estimate along the lateral direction at various points on the curve, and does not attempt to capture uncertainty along the longitudinal direction of the curve. Additionally, our method incorporates expected road curvature information derived from an empirical study of a real road network. Our method is notable in that it accurately captures the geometry of arbitrarily complex lane boundary curves that are not well approximated by straight lines or low-order polynomial curves. Our method operates independently of the direction of travel of the vehicle, and incorporates sensor uncertainty associated with individual observations. We analyze the benefits and drawbacks of the approach, and show results of our algorithm applied to real world data sets.
Effect of pH on binding of agonists and antagonists to rat heart muscarinic receptors (1983)

The pH-dependence of antagonist and agonist binding to rat heart muscarinic receptors was investigated at 25 degrees C, in the absence and in the presence of GTP. The small inhibitory effect observed at the lowest pH investigated (pH 6.0) on [N-methyl-3H]methscopolamine chloride and [methyl-3H]oxotremorine-M acetate binding indicated that one or more amino acid residues of the receptor had to be deprotonated for optimal binding affinity. The low pK value of these residues (between 5 and 6) prevented their identification. The binding of scopolamine (pK 7.6) was favoured by a positive charge in the titratable amine, but binding with a lower affinity remained possible charge in the titratable amine, but binding with a lower affinity remained possible without this charge. GTP did not affect antagonist binding at any pH, but converted more than 90% of agonist binding sites into a low affinity conformation. In the absence of GTP, we observed a time- and pH-dependent conversion of the super-high- and high-affinity receptors to a low-affinity GTP-insensitive state. This conversion was markedly accelerated at high pH (above pH 8.0). In the presence of GTP, a positive charge on the titratable amine of pilocarpine (pK 7.05) and oxotremorine (pK 8.60) was required for binding. These results support the view that antagonist (e.g. methscopolamine) binding to receptors was largely facilitated by hydrophobic interactions, whereas agonist binding to low-affinity sites was mainly driven by ionic interactions.
Enhanced Beaconless Synchronization for Regulatory Domain Specific IEEE 802.15.4g Smart Utility Networks (2012)

This paper proposes a generic enhanced beaconless synchronization mechanism for industrial standard IEEE 802.15.4g Smart Utility Networks (SUN) in multiple regulatory domains globally. IEEE 802.15.4g has specified different regulatory domains for SUN applications, each with a distinctive set of channelization and corresponding operating parameters such as center frequency, channel width and channel spacing. This has added new challenges not limited to, but particularly in beaconless synchronization mechanism supporting low energy consumption demands in conventional IEEE 802.15.4 low rate wireless personal area networks (WPANs). This paper first provides the updates in the SUN technical specification, identifies the challenges due to the effort of addressing multi-regional governing regulatory demands and then proposes a generic solution to tackle the problem. This simple but straightforward approach is preferable in industrial applications with strict energy efficiency requirement. The proposed beaconless synchronization mechanism has outlined two metrics with conflicting interest, namely required time to achieve synchronization and effective bandwidth for data communication. As a result, it is found that as the input radio resource increases, the effective communication bandwidth increases exponentially, while the required time for synchronization increases only linearly.
Design and function of novel osteoblast-adhesive peptides for chemical modification of biomaterials (1998)

Proactive, "next generation" dental/orthopedic biomaterials must be designed rationally to elicit specific, timely, and desirable responses from surrounding cells/tissues; for example, such biomaterials should support and enhance osteoblast adhesion (a crucial function for anchorage-dependent cells). In the past, integrin-binding peptides have been immobilized on substrates to partially control osteoblast adhesion; the present study focused on the design, synthesis, and bioactivity of the novel peptide sequence Lys-Arg-Ser-Arg that selectively enhances heparan sulfate-mediated osteoblast adhesion mechanisms. Osteoblast, but not endothelial cell or fibroblast, adhesion was enhanced significantly (p < 0.05) on substrates modified with Lys-Arg-Ser-Arg peptides, indicating that these peptides may be osteoblast- or bone cell specific. Blocking osteoblast cell-membrane receptors with various concentrations of soluble Arg-Gly-Asp-Ser peptides did not inhibit subsequent cell adhesion on substrates modified with Lys-Arg-Ser-Arg peptides, providing evidence that osteoblasts interact with Arg-Gly-Asp-Ser and with Lys-Arg-Ser-Arg peptides via distinct (i.e., integrin- and proteoglycan-mediated) mechanisms, each uniquely necessary for osteoblast adhesion. The present study constitutes an example of rational design/selection of bioactive peptides, confirms that osteoblast adhesion to substrates can be controlled selectively and significantly by immobilized peptides, and elucidates criteria and strategies for the design of proactive dental/orthopedic implant biomaterials.
Synthesis and Self-Cleavage Reaction of a Chimeric Molecule between RNase P-RNA and Its Model Substrate1 (1995)

We synthesized a chimeric RNA between the catalytic RNA subunit of RNase P from Escherichia coli (M1 RNA) and a model substrate of the enzyme. The model substrate is the smallest substrate of RNase P, having a simple stem-loop structure. This model substrate was added to the 3'-end of M1 RNA. This chimeric molecule, which we call M1 RNA-MS, is a self-cleaving RNA and is cleaved much more efficiently than the M1 RNA-pre-tRNA, an artificial self-cleaving RNA previously synthesized [Kikuchi et al. (1993) Nucleic Acids Res. 21, 4685-4689], that consists of a full-size tRNA precursor and the M1 RNA. The self-cleavage of M1 RNA-MS at 10 mM Mg2+ was an intramolecular reaction (cis-cleavage). Ca2+ supported the self-cleavage of M1 RNA-MS as effectively as Mg2+, although the self-cleavage of M1 RNA-pre-tRNA proceeded with low efficiency in the presence of Ca2+ as the only metal ion. Future application of the M1 RNA-MS molecule to the in vitro evolution of the M1 RNA and other experiments is proposed.
Beyond the H<sub>2</sub>/CO<sub>2</sub>upper bound: one-step crystallization and separation of nano-sized ZIF-11 by centrifugation and its application in mixed matrix membranes (2015)

Nano-sized ZIF-11 with similar features to ZIF-11 has been used for the adsorption of H<sub>2</sub>and CO<sub>2</sub>and in the preparation of mixed matrix membranes for H<sub>2</sub>/CO<sub>2</sub>separation.
Acid-Labile, Chain-Scission Polymer Systems Used as Positive-Tone Photoresists Developable in Supercritical CO<sub>2</sub> (2008)

A new type of acid-catalyzed, chain-scission polymeric system is reported based on main-chain acetal linkages and designed for solubility selectivity in supercritical (sc) CO2. These low-molecular-weight polymer segments, formed by the stepwise polymerization of divinyl ethers and dihydroxy-based monomers, are linked together to render these individually soluble components insoluble in scCO2. Upon exposure to an acid, the linkages are cleaved and result in a system soluble in both aqueous base and scCO2, two widely disparate solvents. This fact is utilized to make a positive-tone photoresist system developable in scCO2 as well as aqueous developer. This represents to the best of our knowledge the first known report of an intrinsically positive-tone photoresist developable in pure scCO2. Excellent solubility contrasts are shown and feature sizes below 200 nm can be obtained with this system.
Vibration-insensitive interferometer for on-line measurements (1995)

We have realized a digital Twyman-Green interferometer to measure the quality of optical surfaces in unstable environments. The system yields accurate measurements even in the presence of severe mechanical vibrations. The interferograms are decoded by application of a spatial-carrier phase-shifting fringe-analysis technique. The interferometer was mounted over a production machine and used for on-line measurements of aspheric mirror surfaces during the figuring and polishing process.
Sizing Equations for Electrical Machinery (1987)

Sizing equations for electrical machinery are developed from basic principles. The technique provides new insights into: 1. The effect of stator inner and outer diameters. 2. The amount of copper and steel used. 3. A maximizing function. 4. Equivalent slot dimensions in terms of diameters and flux density distribution. 5. Pole number effects. While the treatment is analytical, the scope is broad and intended to assist in the design of electrical machinery. Examples are given showing how the machine's internal geometry can assume extreme proportions through changes in basic variables.
High volume manufacturing of polymer planar waveguides via UV embossing (2000)

A process is described here which is capable of creating very low cost single or multimode waveguides. To reuce the cost of manufacture to the lowest levels, one must move away from intensive individual processing steps such as wafer- based spin coating, lithography, and development. Here, a process is described which is inspired by the printing industry; especially the printing of raised features to form simple, low cost holograms typically used for product security. All efforts must be approached with a level of precision and engineering not typically required in the embossing industry. Precision resist masters of 12' dimension were created using commercially available photoresists and photomasks. High fidelity molds (and embossing tools) were made by replicating the master in both metal and elastomer. PET film was coated with an underclass layer which uniformly reproduced waveguide channel features. The filling process of waveguide cores proceeded through the coating of the channels followed by lamination of an overcoating. Finally, end face preparation was examined through die cutting, slitting, and laser cutting techniques.
A CMOS Rectifier With a Cross-Coupled Latched Comparator for Wireless Power Transfer in Biomedical Applications (2012)

A highly efficient rectifier for wireless power transfer in biomedical implant applications is implemented using 0.18-m CMOS technology. The proposed rectifier with active nMOS and pMOS diodes employs a four-input common-gate-type capacitively cross-coupled latched comparator to control the reverse leakage current in order to maximize the power conversion efficiency (PCE) of the rectifier. The designed rectifier achieves a maximum measured PCE of 81.9% at 13.56 MHz under conditions of a low 1.5-V <sub xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">pp</sub> RF input signal with a 1- k output load resistance and occupies 0.009 mm <sup xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">2</sup> of core die area.
Editing of the Bacillus subtilis Genome by the CRISPR-Cas9 System (2016)

In prokaryotes, most methods used for scarless genome engineering are based on selection-counterselection systems. The disadvantages are often the lack of a suitable counterselection marker, the toxicity of the compounds needed for counterselection, and the requirement of certain mutations in the target strain. CRISPR-Cas systems were recently developed as important tools for genome editing. The single-plasmid system constructed for the genome editing of B. subtilis overcomes the problems of counterselection methods. It allows deletions and introduction of point mutations. It is easy to handle and very efficient, and it may be adapted for use in other firmicutes.
Blends of Elastomers and Thermoplastics—A Review (1976)

Abstract In blends of elastomers and thermoplastics one component may be regarded as reinforcing the other. Examples are enhancement of tensile strength, tear strength, abrasion resistance, and modulus of elastomers by thermoplastics and improvement of impact resistance and environmental stress-cracking resistance of thermoplastics by elastomers. Certain elastomer-thermoplastic blends are rapidly growing in importance as thermoplastic rubbers because they combine the processing characteristics of plastics with physical properties similar to those of vulcanized elastomers.
