Scalable Self-Configuring Integration of Localization and Indexing in Wireless Ad-Hoc Sensor Networks (2006)

Data applications in wireless ad hoc sensor networks require scalable localization methods and dynamic data space partitioning among sensors to support efficient query processing. These challenges are exacerbated by sensors’ inherent constraints in storage capability, battery power, processing speed and communication bandwidth. To meet the imperative of energy preservation in data manipulation operations without performance degradation, we propose a scalable and self-configuring scheme, which synergistically integrates localization and data space partitioning, thus minimizing the otherwise prohibitive cost of separately performing localization and/or indexing. We first introduce a basic scheme, called ”simple PRDS”, which enables sensors to self-configure into a consistent coordinate system and to dynamically partition the data space in a network with a small core (at least 15% to 20%) of randomly scattered location-aware sensors within the geographical area spanning the network. We then propose an adaptive version of PRDS, which adds a refinement phase driven by a forcebased relaxation method called mass-spring optimization, to the basic scheme to handle cases where the fraction of location-aware sensors is significantly reduced. Seamless transition is achieved between the basic scheme and refinement phase by assessing the current requirement of the network, while concomitantly, without user intervention, performing efficient local re-adjustment of the data space partitioning among neighborhood sensors. Our experiments, under a varying number of location-aware sensors, show that the "adaptive PRDS" achieves better results than the "simple PRDS" at the cost of a small increase in latency, and is significantly superior to the combination of the best previously proposed techniques for localization and indexing.
Charge calculations in molecular mechanics 6: the calculation of partial atomic charges in nucleic acid bases and the electrostatic contribution to DNA base pairing (1988)

A previously described scheme for the direct calculation of the partial atomic charges in molecules (CHARGE2) is applied to the nucleic acid bases. It is shown that inclusion of the omega-technique for the calculation of HMO derived pi charges is of particular importance for these highly polar systems. The molecular dipole moments obtained for the resulting charges are in very good agreement with the observed values for a variety of substituted purine and pyrimidine bases. The partial atomic charges for cytosine, thymine, guanine and adenine (as the 1-methyl and 9-methyl forms) are given and compared with values calculated by a variety of molecular orbital and empirical schemes. All the schemes reproduce the same general trends, with the possible exception of those calculated by the Del Re method, though the charges given by Kollman are in general somewhat larger than the others. The electrostatic contribution to the Watson-Crick base pair interaction energies are calculated using these partial atomic charges. The electrostatic contributions obtained from the M.O. derived atomic charges are less than half the observed values, as are those obtained by the Gasteiger method. The electrostatic contributions calculated from the CHARGE2 atomic charges and those of Kollman are in reasonable agreement with the observed values. The influence of a distant-dependent dielectric constant is examined, but no clear pattern emerges.
Color and Texture Based Identification and Classification of food Grains using different Color Models and Haralick features (2013)

Abstract — This paper presents the study on identification and classification of food grains using different color models such as L*a*b, HSV, HSI and YCbCr by combining color and texture features without performing preprocessing. The K-NN and minimum distance classifier are used to identify and classify the different types of food grains using local and global features. Texture and color features are the important features used in the classification of different objects. The local features like Haralick features are computed from co-occurrence matrix as texture features and global features from cumulative histogram are computed along with color features. The experiment was carried out on different food grains classes. The non-uniformity of RGB color space is eliminated by L*a*b, HSV, HSI and YCbCr color space. The correct classification result achieved for different color models is quite good.
BIWEEKLY IN-OFFICE INJECTABLE TREATMENT OF STRIAE DISTENSAE VS A LONG-TERM DAILY USE OF TOPICAL VITAMIN C (2001)

Summary The treatment of striae distensae (SO) is difficult, generall y unsatisfactory, and no placebo-controlled study has been carried out to ascerta in the effect of di fferent topica! treatments. The aim of thi s study was to contro! the acti vity of both an office injectable treatme nt and a topica) treatment of water solutions of vitamin C, betaglu can and hyaluronic acid (active A). A sin gle blind placebo-controll ed randomi zed comparative clinica! study was performed on 66 wo­ men aged between 18-24, with SO localized over the abdomen and buttocks. The subjects were d i­ vided in to 3 study groups. Active B was applied at home twice a day for 16 weeks to 24 patients (group A). Twice a week they received also derma) injecti on of active A fo r the entire period. 22 pa­ tients in group B appl ied, twice a day, active B for 16 weeks. The remaini ng 20 patients in group C applied a placebo solution (distilled water) twice daily during the same period. The differences between the results in the differe nt groups were stati stically significant at week l 2 and 16 (p<0.05) both by visual score and by istologica] contro! performed. However, the combined use of inj ection and topica! application (group A) provided superior results ( +57%, p<0.05) compa­ red wi th th e group B (topica] treatment onl y) (+32% p<0.05 vs. pl acebo). No sid e effects were ob­ served during the treatment period, except a light burning at the moment of the injection. No results from placebo. The combined topical and injectable use of vitamin C, betaglucan and hyaluronan seems to be effec­ tiv e to stimulate celi proliferati on provided that the right concentration of the active with the right canier is used.
<title>Measurement of microlithography aerial image quality</title> (1996)

The aerial image formed by a microlithography lens places fundamental limits on the size and density of patterns that are manufactured by that lens. In the past, the lithographer was unable to directly measure the dose distribution in this aerial image. Highly absorbing photoresists have continuous tone relief response to dose variations and this relief is a record of the dose distribution in an image. It is shown how high resolution measurement of that relief by an atomic force microprobe gives the lithographer a sampling of the spatial distribution of dose within the image.

A virtual machine for a functional mobile agent architecture supporting distributed medical information (2003)

A virtual machine supporting mobile software agents using the functional programming paradigm is presented. This virtual machine provides for the application developer a rich and robust platform on which to develop distributed mobile agent applications, specifically when targeting distributed medical information and distributed image processing. The functional paradigm provides the virtual machine and applications developed for it with a conciseness and expressiveness not normally available with other paradigms, and directly supports distribution by exploiting the natural parallelism inherent an functional programs.
Metal-Supported SOFC with Ceramic-Based Anode (2011)

Metal-supported solid oxide fuel cells have shown promise to offer several potential advantages over conventional anode (Ni-YSZ) supported cells, such as increased resistance against mechanical and thermal stresses and a reduction in materials cost. The purpose of this work is to illustrate how the metal-supported cell concept can be combined with ceramic-based anode materials, such as Nb-doped SrTiO3. The paper shows that a metal-supported cell can have excellent performance by only having electronically conducting phases in the anode backbone structure, into which electrocatalytically active materials are infiltrated after sintering. Initial area specific resistance as low as 0.3 Ωcm2 at 700 ºC has been obtained with power densities > 1 Wcm-2. The initial results on the chemical compatibility, electrochemical performance, and galvanostatic durability of a ceramic based (Nb-doped SrTiO3), zirconia-free anode, in a planar metal-supported SOFC concept is discussed.
Security Door System Using Human Tracking Method with Laser Range Finders (2007)

Recently, tracking and counting people are requested for the security purpose. In this paper, we propose a method to track and count people with laser range finders. A method to extract the walking human from the sensor data is introduced. Multi-target model and Kalman filter based estimation are employed to track the human movement and count the number of people. The proposed method is applied to a novel system to monitor the entrance area and to filter out the trespasser who enters the door without identification. Experiments for various cases are performed to verify the usefulness of developed proto-type system.
Scanning optical microscopy (1985)

Abstract The scanning optical microscope, provides new information about a wide variety of specimens. The confocal mode provides a form of super‐resolution and allows the depth of field of the microscope to be tuned at will, and extended, in principle, without limit. The instrument is particularly advantageous for the study of materials and devices, especially semiconductors. The image is built up on a cathode ray tube display by mechanically scanning the object across a focussed spot.
A logic for causal inference in time series with discrete and continuous variables (2011)

Many applications of causal inference, such as finding the relationship between stock prices and news reports, involve both discrete and continuous variables observed over time. Inference with these complex sets of temporal data, though, has remained difficult and required a number of simplifications. We show that recent approaches for inferring temporal relationships (represented as logical formulas) can be adapted for inference with continuous valued effects. Building on advances in logic, PCTLc (an extension of PCTL with numerical constraints) is introduced here to allow representation and inference of relationships with a mixture of discrete and continuous components. Then, finding significant relationships in the continuous case can be done using the conditional expectation of an effect, rather than its conditional probability. We evaluate this approach on both synthetically generated and actual financial market data, demonstrating that it can allow us to answer different questions than the discrete approach can.
High‐energy electron beams launched into space by thunderstorms (2008)

Using CGRO/BATSE data, a possible new source of high‐energy electrons and positrons in the earth's inner magnetosphere is presented. These particles are generated within the upper atmosphere by Compton scattering and pair‐production of gamma‐rays originating from near the tropopause as Terrestrial Gamma‐ray Flashes (TGFs). Once created, these energetic electrons and positrons follow the geomagnetic field into the inner magnetosphere where they can be detected in low‐earth orbit, either near the TGF magnetic foot point or at the conjugate point several thousand kilometers away. Approximately 17% of CGRO/BATSE events previously identified as terrestrial gamma‐ray flashes are, in fact, such electrons and positrons. With energies extending above 30 MeV, this previously unidentified population contains some of the most energetic particles accelerated in the near‐earth environment.
Advances in the Synthesis of Ferrierite Zeolite (2020)

As one of the most important porous materials, zeolites with intricate micropores have been widely employed as catalysts for decades due to their large pore volume, high surface area, and good thermal and hydrothermal stabilities. Among them, ferrierite (FER) zeolite with a two-dimensional micropore structure is an excellent heterogeneous catalyst for isomerization, carbonylation, cracking, and so on. In the past years, considering the important industrial application of FER zeolite, great efforts have been made to improve the synthesis of FER zeolite and thus decrease the synthesis cost and enhance catalytic performance. In this review, we briefly summarize the advances in the synthesis of FER zeolite including the development of synthesis routes, the use of organic templates, organotemplate-free synthesis, the strategies of morphology control, and the creation of intra-crystalline mesopores. Furthermore, the synthesis of hetero-atomic FER zeolites such as Fe-FER and Ti-FER has been discussed.
Oxytocin receptors on cultured astroglial cells. Regulation by a guanine-nucleotide-binding protein and effect of Mg2+ (1992)

Specific binding sites for the radio-iodinated oxytocin (OT) antagonist d(CH2)5-[Tyr(Me)2,Thr4, Tyr-NH2(9)]OVT ([125I]OTA) have been characterized on cultured hypothalamic astroglial cell membranes. The rate of association of the ligand to OT-binding sites was identical in the presence and the absence of the non-hydrolysable GTP analogue guanosine 5'-[beta gamma-imido]triphosphate (Gpp[NH]p, 0.1 mM), whereas the monophasic dissociation reaction became biphasic in the presence of Gpp[NH]p. Scatchard analysis of equilibrium binding of [125I]OTA resulted in a linear plot with a single class of binding sites (Kd 0.06 nM) which were insensitive to the addition of Gpp[NH]p. Unlabelled OT and [Arg8]vasopressin (AVP) bound to high- (H) and low- (L) affinity states with a dissociation constant ratio (KL/KH) of 100 for both hormones. Binding with both high and low affinity required the presence of Mg2+ in the incubation buffer, and the addition of Gpp[NH]p decreased the KL/KH ratio to 10 and increased the percentage of low-affinity binding sites. On the other hand, neither omission of Mg2+ from the buffer nor the addition of Gpp[NH]p altered the binding of either OT or V1 AVP antagonists to OT receptors. In the presence of a G-protein inactivator (N-ethylmaleimide; 3 mM) during OT competition studies the affinities of the two OT-binding sites were unchanged, but 90% of the high-affinity binding sites were converted into the low-affinity state. These results obtained with cultured hypothalamic astroglial cells provide further evidence for a coupling of OT receptors with a guanine-nucleotide-binding protein, with a requirement for Mg2+.
Can computed crystal energy landscapes help understand pharmaceutical solids? (2016)

Computational crystal structure prediction (CSP) methods can now be applied to the smaller pharmaceutical molecules currently in drug development. We review the recent uses of computed crystal energy landscapes for pharmaceuticals, concentrating on examples where they have been used in collaboration with industrial-style experimental solid form screening. There is a strong complementarity in aiding experiment to find and characterise practically important solid forms and understanding the nature of the solid form landscape.
Spacing and Site Isolation of Amine Groups in 3-Aminopropyl-Grafted Silica Materials:  The Role of Protecting Groups (2006)

The relative spacing of amines in 3-aminopropylsilyl-grafted silica is studied by solid-state fluorescence spectroscopy of 1-pyrenecarboxylic acid (PCA) and 1-pyrenebutyric acid (PBA) bound to traditionally prepared, deprotected benzyl- or deprotected trityl-spaced aminosilicas. Thermogravimetric analysis and FT-Raman spectroscopy results show evidence that the protected imine can be cleaved to yield the corresponding amine in essentially quantitative yield. The steady-state fluorescence spectroscopic data of either PCA or PBA indicate that the number of amine pairs on the surface separated by a distance of 1 nm or less decreases as the total amine loading decreases. Both the intensity ratio of the excimer band to the monomer band (I470/I384 or Iexc/Imon) and lifetime decay studies of the fluorophore are useful probes of the amine spacing. Separation of amines on the surface can be achieved by either use of a protected synthesis route or through reduction of the concentration of the unprotected 3-aminopropyltrimethoxysilane used in the grafting solution. However, the two routes lead to materials with significantly different average amine spacings. Due to clustering of unprotected amines in solution before grafting or on the surface during the grafting process, amine−amine distances on the surface of materials prepared by an unprotected synthesis are on average smaller than when a protected synthesis is used. With the protected synthesis, evidence suggests that the amines are more isolated, with larger average amine−amine distances when compared to corresponding materials with a similar amine loading prepared via an unprotected synthesis. This is attributed to both the steric influence of the protecting groups and a reduction in silane clustering in solution due to protection of the amines before grafting. Thus, the mechanism of surface amine spacing when using the protection−deprotection strategy appears to involve both of these factors (especially in the case of trityl-spaced samples).
Some aspects of the electrochemical machining process supported by electrode ultrasonic vibrations optimization (2003)

Primary investigations of the electrochemical micromachining process supported by electrode ultrasonic vibrations have been carried out. As a result the basic characteristic of this process and optimal process parameters for which surface roughness is minimal have been found. It has been proved that electrode ultrasonic vibrations help to decrease the surface roughness parameter R a in comparison to the classical electrochemical process. The analyses of phenomena occurring in the machined area and indications for further investigations have been also presented.
Think globally, act locally: decentralized supervisory control (1992)

Decentralized supervisory control is investigated by considering problem formulations that model systems whose specifications are given as global constraints, but whose solution is described by local controllers. A necessary and sufficient condition is given for the existence of a solution to the problem of finding decentralized supervisors that ensure that the behavior of the closed-loop system lies in a given range. Where the range of behavior can be described by regular languages, it can be effectively tested whether the decentralized control problem is solvable; in this case, a procedure is given to compute the associated supervisors.< <ETX xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">></ETX>

The timberland owner must balance future benefits against present expenditures, and in managing his woodland silvicultural practice will be influenced by relative immediate costs.
Systemic κ-opioid receptor antagonism by nor-binaltorphimine reduces dependence-induced excessive alcohol self-administration in rats (2010)

Altered dynorphin opioid peptide systems contribute to increased ethanol self-administration during withdrawal following chronic alcohol exposure. We previously identified that the κ-opioid receptor antagonist nor-binaltorphimine (nor-BNI) selectively reduced ethanol self-administration in dependent animals. The purpose of this study was twofold: (1) determine whether peripherally administered nor-BNI could reduce dependence-induced ethanol self-administration and (2) confirm the selective κ-opioid effects of nor-BNI by administering it 24 hours prior to ethanol self-administration sessions occurring during acute withdrawal. Nor-BNI decreased ethanol self-administration in ethanol-dependent animals, with no effect in nondependent animals. Thus, the κ-opioid/dynorphin system is a viable pharmacotherapeutic target for the treatment of alcoholism.
