Target correlation algorithm between two-dimensional angle sensors (1999)

When several moving targets are detected by two two-dimensional angle sensors (elevation and azimuth angles) separately spaced, three-dimensional tracking of each target is possible if the range to each target is computed by triangulation. What is important in such a step is correlation processing to find out which pairs of sensor information are obtained from the same target. Especially, if several targets enter a region that can be considered within the same plane seen from the two angle sensors, a false intersection with no actual target, namely, a ghost, is generated among the intersections of the line of sight from the sensor to the target so that the correlation process becomes difficult. In this paper, the angle and angular velocity of the target with respect to each sensor are tracked by an angle tracking filter. The proposed system for the correlation process carries out discrimination of the same target by using the angle tracking results. By means of simulation, the performance of the proposed system is investigated. It is made clear that the proposed system can effectively eliminate the ghosting when several targets enter temporarily the same plane. © 1998 Scripta Technica, Electron Comm Jpn Pt 1, 82(2): 30–38, 1999

Horses at the Grocery (2004)

Horses at the GroceryHe pushed the shopping cart around the corner of the aisle, wrestling with it as he felt the back left wheel stick, then drag across the tile floor.Rolling his eyes up at the ceiling, he sighed.No matter how carefully he examined the shopping carts, no matter if he pushed and pulled them as he had this one, a wheel would inevitably fail.It would jam up or wobble, or when he placed a bag of cat food on the bottom rack when it was half loaded with milk, bread, and bagels, it would reveal itself to have a bad bushing, which would only get worse as he piled on more groceries."Why do I expect to find grocery carts that work the way they're supposed to?"He was midway down the aisle now and stopped.Was it getting late?How many times had he come this way already?He scanned the shelves, trying to remember what it was he needed.There was coffee and tea to his left, but no, he didn't drink coffee and he bought his tea at a little shop in his neighborhood.He looked at the other side of the aisle.Cereal, cereal snacks, granola bars, oatmeal -yes, oatmeal.A nice, big bag of oatmeal.Plenty of oatmeal.From oats.Oats are good/or you and/or me."Oats are good for horses, too," he added aloud.A little boy pushing his own child-sized cart looked at the man and then at his mother."Mommy, that man's got oatmeal for his horses."His mother absently replied, "Yes, honey."She was reaching for a box of Fruit Loops.She glanced at the man, and he saw her face start to shift into a mask of obligatory grocery store politeness, saw her eyes flick down, watched as her face shifted again to puzzlement, and then she quickly turned away.He followed where her eyes had gone, down to his own cart.It was piled high with five pound bags of oatmeal.On the bottom rack was a bag of cat food.The man stared at the small mountain of grain in front of him.Do I have horses?He wrinkled his forehead, squinting and thinking hard to remember.
Curved fiber bundles for monocentric lens imaging (2015)

Monocentric lenses allow high resolution panoramic cameras, where imaging fiber bundles transport the hemispherical image surface to conventional focal planes. Refraction at the curved image surface limits the field of view coupled through a single bundle of straight fibers to less than ±34°, even for NA 1 fibers. Previously we have demonstrated a nearly continuous 128° field of view using a single lens and multiple adjacent straight fiber-coupled image sensors, but this imposes mechanical complexity of fiber bundle shaping and integration. However, a 3D waveguide structure with internally curved optical fiber pathways can couple the full continuous field of view onto a single focal plane. Here, we demonstrate wide-field imaging using a monocentric lens and a single curved fiber bundle, showing that the 3D bundle formed from a tapered fiber bundle can be used for relaying a 128° field of view from a curved input to the planar output face. We numerically show the coupling efficiency of light to the tapered bundle for different field of views depends on the taper ratio of the bundle as well as center of the curvature chosen for polishing of the fiber bundle facet. We characterize a tapered fiber bundle by measuring the angle dependent impulse response, transmission efficiency and the divergence angle of the light propagating from the output end of the fiber.

Blind estimation of FIR channels in CDMA systems with aperiodic spreading sequences (2002)

CDMA systems commonly use aperiodic spreading codes to distribute a signal spectrum uniformly over the channel bandwidth and differentiate neighboring cell sites. CDMA receivers often suffer from interference due to multipath fading. Blind signal estimation schemes cannot be used because they require periodic spreading sequences. RAKE receivers are often used, but they cannot fully exploit the rich structure of CDMA signals to minimize interference. This paper presents an iterative technique to estimate multipath parameters which can serve as a preprocessing step in a receiver to increase signal-to-interference ratio. We investigate the performance of the proposed method using computer simulations. Preliminary simulation results show an average of 10 dB gain on channel parameter estimation.
Equistatin, a new inhibitor of cysteine proteinases from Actinia equina, is structurally related to thyroglobulin type-1 domain. (1998)

Page 13901: In the course of studies that involved resequencing of equistatin molecule, an error in the published sequence was discovered. Consequently, Figs. 3 and 4should be replaced by the following figures. These lead to the conclusion that equistatin is not a two-domain protein as previously described, but a three-domain protein with molecular weight of 21,755. The inhibition properties and other characteristics are unchanged.
Size-dependent enhancement of superconductivity in Al and Sn nanowires: Shape-resonance effect (2006)

A shape-dependent superconducting resonance can be expected when an energy level associated with the transverse motion in a wire passes through the Fermi surface. We show that the recently observed width-dependent increase of ${T}_{c}$ in Al and Sn nanowires is a consequence of this shape-resonance effect.
Iron promoters of the Fenton reaction and lipid peroxidation can be released from haemoglobin by peroxides (1986)

Hydrogen peroxide and organic hydroperoxides react with haemoglobin to release iron which can be complexed to apotransferrin, bleomycin and desferrioxamine. This released iron promotes deoxyribose degradation by a Fenton reaction, DNA degradation in the presence of bleomycin and stimulates lipid peroxidation. It is likely that iron released from haemoglobin is the true generator of hydroxyl radicals in the Fenton reaction.
Properties of crude laccase from Trametes versicolor produced by solid-substrate fermentation (2010)

A low-cost process for the production of laccases is necessary for a sustainable enzymatic wastewater treatment. Therefore, it is necessary to establish an easy and low-cost procedure for the production of laccase. In the present study the properties of crude laccase from Trametes versicolor produced by solid-substrate fermentation is investigated. The application of the enzyme for dye decolorization is also studied. Crude laccase from the studied culture established maximal activity at 45ºC. The enzyme retained over 90% of its activity in the temperature range 40- 47ºC and pH 4.5. The kinetic constants of the crude enzyme was also determined. In the presence of KCl, NaCl, CaCl2, MnSO4 and MgSO4, laccase demonstra- ted high stability—over 50% of its initial activity was still retained after 4-month incubation. Complete loss of enzymatic activity was observed in the presence of CuCl2, FeCl2, FeCl3 and NaN3 after 30 min of incubation. 100% decolorization by investigated crude laccase was completed in the case of Indigo Carmine for 4 h, Remazol Brilliant Blue R—for 6 h, Orange II— for 48 h and Congo Red—for 13 d.
All-optical spatial light modulator with surface plasmon resonance (1993)

An all-optical photoaddressed spatial light modulator has been demonstrated. The device consists of a prism of high refractive index coated with a thin silver film and a dye-doped polymer film. The writing beam photothermally changes the distribution of the refractive index of the dye-doped film. The reading beam, of a different wavelength, which is incident upon the prism near an angle for surface plasmon resonance at the metal–dye-doped-film interface, undergoes modulation on reflection. Both positive and negative modulation is possible when suitable angles of incidence are chosen for the reading beam. We obtained a resolution of 15 line pairs/mm, an ∼10-s rise time, a 2-s fall time.
Erythropoietin assay in mice made polycythemic by transfusion of heterologous red cells. (1999)

A simple in vivo bioassay suitable for routine testing of quality control of recombinant human erythropoietin (rHu-EPO) analogues was developed. Mice made polycythemic by intraperitoneal injection of 1.2 ml of a 80% suspension of heterologous (rat) red cells were used as assay animals and splenic 59Fe uptake as expression of the response to rHu-EPO. The assay took three days and the following schedule is proposed: 1) intraperitoneal injection of 1.2 ml of washed packed red cells obtained from donor rats, 2) subcutaneous injection of test material 4-5 h after transfusion, 3) intravenous administration of 59Fe tracer 48 h later, and 4) determination of splenic isotope uptake 6 h after injection. This method for the in vivo bioassay of rHu-EPO analogues is an economical and reliable alternative to the existing bioassays of the hormone.
On-site education of VEGF-recruited monocytes improves their performance as angiogenic and arteriogenic accessory cells (2013)

Adult neovascularization relies on the recruitment of monocytes to the target organ or tumor and functioning therein as a paracrine accessory. The exact origins of the recruited monocytes and the mechanisms underlying their plasticity remain unclear. Using a VEGF-based transgenic system in which genetically tagged monocytes are conditionally summoned to the liver as part of a VEGF-initiated angiogenic program, we show that these recruited cells are derived from the abundant pool of circulating Ly6C(hi) monocytes. Remarkably, however, upon arrival at the VEGF-induced organ, but not the naive organ, monocytes undergo multiple phenotypic and functional changes, endowing them with enhanced proangiogenic capabilities and, importantly, with a markedly increased capacity to remodel existing small vessels into larger conduits. Notably, monocytes do not differentiate into long-lived macrophages, but rather appear as transient accessory cells. Results from transfers of presorted subpopulations and a novel tandem transfer strategy ruled out selective recruitment of a dedicated preexisting subpopulation or onsite selection, thereby reinforcing active reprogramming as the underlying mechanism for improved performance. Collectively, this study uncovered a novel function of VEGF, namely, on-site education of recruited "standard" monocytes to become angiogenic and arteriogenic professional cells, a finding that may also lend itself for a better design of angiogenic therapies.
A Multilayer MEMS Platform for Single-Cell Electric Impedance Spectroscopy and Electrochemical Analysis (2008)

The fabrication and characterization of a microchamber electrode array for electrical and electrochemical studies of individual biological cells are presented. The geometry was tailored specifically for measurements from sensory hair cells isolated from the cochlea of the mammalian inner ear. Conventional microelectromechanical system (MEMS) fabrication techniques were combined with a heat-sealing technique and polydimethylsiloxane micromolding to achieve a multilayered microfluidic system that facilitates cell manipulation and selection. The system allowed for electrical stimulation of individual living cells and interrogation of excitable cell membrane dielectric properties as a function of space and time. A three-electrode impedimetric system was incorporated to provide the additional ability to record the time-dependent concentrations of specific biochemicals in microdomain volumes near identified regions of the cell membrane. The design and fabrication of a robust fluidic and electrical interface are also described. The interface provided the flexibility and simplicity of a "cartridge-based" approach in connecting to the MEMS devices. Cytometric measurement capabilities were characterized by using electric impedance spectroscopy (1 kHz-10 MHz) of isolated outer hair cells. Chemical sensing capability within the microchannel recording chamber was characterized by using cyclic voltammetry with varying concentrations of potassium ferricyanide (K(3)Fe(CN)(6)). Chronoamperometric recordings of electrically stimulated PC12 cells highlight the ability of the platform to resolve exocytosis events from individual cells.
A Mathematical Model for the Transient Stability Analysis of a Simultaneous AC–DC Power Transmission System (2017)

The outcome of recent numerical simulation shows that the conversion of an AC transmission line to a simultaneous AC-DC line improves the system stability. This paper presents a mathematical model, suitable for the stability analysis of a simultaneous AC-DC transmission system, transmitting both AC and DC powers simultaneously through an existing AC line. The model is based on the principle of equal area criterion. The salient feature of this model is the introduction of a solution technique of an integral component of the model, which avoids the trial and error approach for the analysis. The model development process considers a single machine-infinite bus system with a transmission line connecting the machine and the infinite bus. The process also considers the severe most fault at the sending end bus. The validation of the model is executed through two different approaches; comparison of the results obtained applying the proposed model to the power system with the published ones in the literature and with the results obtained using standard software, MATLAB-Simulink, based circuit simulations. The model is also applied to a realistic system and IEEE benchmark systems to verify its capability of evaluating the benefits of a simultaneous AC-DC transmission system.
Increased expression of mRNA encoding interleukin (IL)‐4 and its splice variant IL‐4δ2 in cells from contacts of <i>Mycobacterium tuberculosis</i>, in the absence of <i>in vitro</i> stimulation (2004)

Expression of interleukin (IL)-4 is increased in tuberculosis and thought to be detrimental. We show here that in healthy contacts there is increased expression of its naturally occurring antagonist, IL-4delta2 (IL-4delta2). We identified contacts by showing that their peripheral blood mononuclear cells (PBMC) released interferon (IFN)-gamma in response to the Mycobacterium tuberculosis-specific antigen 6 kDa early secretory antigenic target (ESAT-6). Fresh unstimulated PBMC from these contacts contained higher levels of mRNA encoding IL-4delta2 (P=0.002) than did cells from ESAT-6 negative donors (noncontacts). These data indicate that contact with M. tuberculosis induces unusual, previously unrecognized, immunological events. We tentatively hypothesize that progression to active disease might depend upon the underlying ratio of IL-4 to IL-4delta2.
Optical emission in periodic dielectrics (1996)

We show rigorously that the coefficient for spontaneous emission of an atom placed in a dielectric is proportional to the local radiative density of states—that is only a part of the local density of the eigenmodes of the Maxwell equations. Spontaneous emission is inhibited if the atom is located at a position where this local radiative density is small, even if the total density of states is not vanishing. This radiative density of states can be obtained without having to perform a full quantum calculation of the radiation-matter system. We demonstrate this principle by solving numerically a scalar model for a dielectric that consists of a lattice of resonating dipoles.
Determination and comparison of heat exchange efficiency of four commercially available blood cardioplegia sets (1994)

An in vitro comparison of the heat exchange properties of the Electromedics D1081A, Sarns MP-4 'Conducer Coil' 165720, Bentley HE-100 and the Shiley BCD Plus 4: 1 blood cardioplegia sets was performed. The efficiency was calculated for each heat exchanger and post-heat exchange blood path temperatures were compared. The calculated efficiency for each heat exchanger is as follows: Electromedics D1081A at 18 l/minute coil water flow (0.95); Sarns MP-4 165720 at 9 l/minute coil water flow (0.93); Bentley HE-100 at 10 l/minute coil water flow (0.91); Shiley BCD Plus at 15 l/minute coil water flow (0.90). Blood path, precoil temperatures for each unit were compared statistically with no differences found (p > 0.05). Blood side, postcoil temperatures were then compared. The average postcoil blood path temperature of the Electromedics D1081A was 1.6 degrees +/- 0.1 degree C, of the Sarns MP-4 165720 it was 2.1 degrees +/- 0.1 degree C, of the Bentley HE-100 it was 2.7 degrees +/- 0.3 degree C, and the Shiley BCD Plus 3.0 degrees +/- 0.4 degree C. The results of this experiment indicate that the average postcoil temperature of the Electromedics D1081A was lower than the Sarns MP-4 165720 (p < 0.05) which was lower than that of the Bentley HE-100 (p < 0.05) and Shiley BCD Plus (p < 0.05). No statistical difference was found between the average postcoil temperature of the Bentley HE-100 and the Shiley BDC Plus.
Beyond effector caspase inhibition (2011)

Malignant gliomas are the most common and lethal primary central nervous system cancer. Glioblastoma mutliforme (GBM), the most aggressive of these neoplasms, are generally lethal within 2 years of diagnosis due in part to the intense apoptosis resistance of its cancer cells, hence poor therapeutic response to conventional and targeted therapies. Twenty years of research has uncovered key genetic events involved in disease initiation and progression, foremost the Tp53 tumor suppressor that is mutated or deleted in 35% of GBM. The prime importance of p53 signaling for gliomapathogenesis is further evidenced by epistatic genetic events targeting additional pathway components including deletion of p14 (Arf) (CDKN2A) and amplification of the p53-degrading ubiquitin ligases MDM2 and MDM4. Recent studies have identified and validated Bcl2-Like 12 (Bcl2L12) as a potent glioma oncoprotein with multiple strategic points in apoptosis regulatory networks, i.e. effector caspases and the p53 tumor suppressor. Bcl2L12 resides in both the cytoplasm and nucleus. In the cytoplasm, Bcl2L12 functions to inhibit caspases 3 and 7, in the nucleus, Bcl2L12 forms a complex with p53, modestly reduces p53 protein stability and prevents its binding to selected target gene promoter (e.g. p21, DR5, Noxa and PUMA), thereby inhibiting p53-directed transcriptomic changes upon DNA damage. Proteomic and multidimensional oncogenomic analyses confirmed a Bcl2L12-p53 signaling axis in GBM, as Bcl2L12 exhibited predominant genomic amplification, elevated mRNA and protein levels in GBM tumors with uncompromised p53 function. On the cell biological level, Bcl2L12 exerts robust inhibition of p53-dependent senescence and apoptosis processes in glioma cells. These multi-leveled studies establish Bcl2L12 as an important oncoprotein acting at the intersection of nuclear p53 and cytoplasmic caspase signaling and point to pharmacological disruption of the Bcl2L12:p53 complex as a promising novel therapeutic strategy for the enhanced treatment of GBM.
Fuzzy-attribute graph with application to Chinese character recognition (1992)

To include fuzzy properties in solving some types of problems, the attributes graph is extended to provide a fuzzy-attribute graph (FAG). With such an extension, equality of attributes can no longer be used when matching of FAGs is considered, as equality of two fuzzy sets is too stringent a condition. A measure for matching two FAGs is suggested. The measure has its interpretation in fuzzy logic. The result of applying the model to the recognition of handprinted Chinese characters is presented.< <ETX xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">></ETX>
Multiagent Web for the Internet of Things (2014)

The Internet of Things (IOT) is a network of networks where massively large numbers of objects or things are interconnected to each other through the network. The Internet of Things brings along many new possibilities of applications to improve human comfort and quality of life. Complex systems such as the Internet of Things are difficult to manage because of the emergent behaviours that arise from the complex interactions between its constituent parts. Our key contribution in the paper is a proposed multiagent web for the Internet of Things. Corresponding data management architecture is also proposed. The multiagent architecture provides autonomic characteristics for IOT making the IOT manageable. In addition, the multiagent web allows for flexible processing on heterogeneous platforms as we leverage off web protocols such as HTTP and language independent data formats such as JSON for communications between agents. The architecture we proposed enables a scalable architecture and infrastructure for a web-scale multiagent Internet of Things.
