Energy efficient sensor, relay and base station placements for coverage, connectivity and routing (2005)

We consider a wireless sensor network made of sensor nodes capable of sensing and communication, relay nodes capable of communication, and base stations responsible for collecting data generated by sensor nodes, to be deployed in sensor field. We address the problem of placing the sensor nodes, relay nodes and base stations in the sensor field such that (i) each point of interest in the sensor field is covered by a subset of sensors of desired cardinality (ii) the resulting sensor network is connected and (iii) the sensor network has sufficient bandwidth. We propose several deployment strategies to determine optimal placements of sensor nodes, relay nodes and base stations for guaranteed coverage, connectivity, bandwidth and robustness. We study several different objectives such as minimizing the number of sensor nodes deployed, minimizing the total cost, minimizing the energy consumption, maximizing the network lifetime and maximizing the network utilization. The placement problems for reliable as well as unreliable/probabilistic detection models are formulated as integer linear programs (ILPs). The practicality, effectiveness and performance of the proposed strategies are illustrated through simulations.
Modeling and Identification of the Combustion Pressure Process in Internal Combustion Engines: II—Experimental Results (1993)

In Connolly and Yagle (1992, 1993) we presented a new model relating cylinder combustion pressure to crankshaft angular velocity in an internal combustion engine, primarily the fluctuations in velocity near the cylinder firing frequency. There are three aspects to this model. First, by changing the independent variable from time to crankshaft angle, a nonlinear differential equation becomes a linear first-order differential equation. Second, a new stochastic model for combustion pressure uses the sum of a deterministic waveform and a raised-cosine window amplitude-modulated by a Bernoulli-Gaussian random sequence, parametrizing the pressure by the sample modulating sequence. This results in a state equation for the square of angular velocity sampled every combustion, with the modulating sequence as input. Third, the inverse problem of reconstructing pressure from noisy angular velocity measurements was formulated as a state-space deconvolution problem, and solved using a Kalman-filter-based deconvolution algorithm. Simulation results in Connolly and Yagle (1992, 1993) show that the parametrized pressure can be deconvolved at low to moderate noise levels, and combustion misfires detected, all in real time. This paper presents and discusses experimental results that confirm this model, at least at the relatively low-speed, low-to-moderate load operating conditions analyzed. They show that cyclic combustion pressure variation is fairly well modeled and may be directly estimated from angular velocity measurements. They also show that the deconvolution algorithm is able to detect misfires and possibly classify their severity. Since the experimental data are taken from an actual V-6 automobile engine, and the algorithms are simple enough to be implemented in real time, these results are directly applicable to real-world combustion pressure identification.
Solution Structure of the Osteogenic 1−31 Fragment of the Human Parathyroid Hormone (2000)

The solution conformations of a selectively osteogenic 1-31 fragment of the human parathyroid hormone (hPTH), hPTH(1-31)NH(2), have been characterized by use of very high field NMR spectroscopy at 800 MHz. The combination of the CalphaH proton and (13)Calpha chemical shifts, (3)J(NH)(alpha) coupling constants, NH proton temperature coefficients, and backbone NOEs reveals that the hPTH(1-31)NH(2) peptide has well-formed helical structures localized in two distinct segments of the polypeptide backbone. There are also many characteristic NOEs defining specific side-chain/backbone and side-chain/side-chain contacts within both helical structures. The solution structure of hPTH(1-31)NH(2) contains a short N-terminal helical segment for residues 3-11, including the helix capping residues 3 and 11 and a long C-terminal helix for residues 16-30. The two helical structures are reinforced by well-defined capping motifs and side-chain packing interactions within and at both ends of these helices. On one face of the C-terminal helix, there are side-chain pairs of Glu22-Arg25, Glu22-Lys26, and Arg25-Gln29 that can form ion-pair and/or hydrogen bonding interactions. On the opposite face of this helix, there are characteristic hydrophobic interactions involving the aromatic side chain of Trp23 packing against the aliphatic side chains of Leu15, Leu24, Lys27, and Leu28. There is also a linear array of hydrophobic residues from Val2, to Leu7, to Leu11 and continuing on to residues His14 and Leu15 in the hinge region and to Trp23 in the C-terminal helix. Capping and hydrophobic interactions at the end of the N-terminal and at the beginning of the C-terminal helix appear to consolidate the helical structures into a V-shaped overall conformation for at least the folded population of the hPTH(1-31)NH(2) peptide. Stabilization of well-folded conformations in this linear 1-31 peptide fragment and possibly other analogues of human PTH may have a significant impact on the biological activities of the PTH peptides in general and specifically for the osteogenic/anabolic activities of bone-building PTH analogues.
Oral ionic liquid for the treatment of diet-induced obesity (2019)

More than 70% of American adults are overweight or obese, a precondition leading to chronic diseases, including diabetes and hypertension. Among other factors, diets with high fat and carbohydrate content have been implicated in obesity. In this study, we hypothesize that the choline and geranate (CAGE) ionic liquid can reduce body weight by decreasing fat absorption through the intestine. In vitro studies performed using docosahexaenoic acid (DHA), a model fat molecule, show that CAGE forms particles 2 to 4 μm in diameter in the presence of fat molecules. Ex vivo permeation studies in rat intestine showed that formation of such large particles reduces intestinal fat absorption. In vivo, CAGE reduces DHA absorption by 60% to 70% compared with controls. DHA administered with CAGE was retained in the intestine even after 6 h. Rats fed with a high-fat diet (HFD) and 10 μL of daily oral CAGE exhibited 12% less body weight gain compared with rats fed with an HFD without CAGE for 30 d. Rats that were given CAGE also ate less food than the control groups. Serum biochemistry and histology results indicated that CAGE was well tolerated by the rats. Collectively, our data support the hypothesis that CAGE interacts with fat molecules to prevent their absorption through intestinal tissue and potentially providing a feeling of satiety. We conclude that CAGE offers an effective means to control body weight and a promising tool to tackle the obesity epidemic.

Comparative analysis of diagnostic and predictive performance of novel renal biomarkers in plasma and urine of acute kidney injury patients (2015)

Renal biomarkers represent an attractive new diagnostic tool which not only implies early diagnosis of AKI, but provides also information about patients at risk for AKI and prediction of adverse clinical outcome parameters like the need for renal replacement therapy, length of stay in ICU and mortality. Biomarker levels in urine however may be altered by intravascular volume availability and chronic renal insufficiency.
Growth-Inhibitory Effects of Serotonin Uptake Inhibitors on Human Prostate Carcinoma Cell Lines (1995)

Growth stimulation of a variety of cell types by the neurotransmitter serotonin has been reported. We have examined the effects of three serotonin-uptake inhibitors, 6-nitroquipazine, zimelidine and fluoxetine (Prozac, Eli Lilly Co., Indianapolis, Indiana) on human prostate carcinoma cell lines. In vitro, all 3 of these compounds inhibited the proliferation of PC-3, DU-145 and LNCaP cells in a dose-dependent manner. Also, all 3 compounds blocked the uptake of a radiolabeled analog of serotonin by the prostate carcinoma cell lines. The order of potency for inhibition of growth as well as for serotonin uptake was fluoxetine > zimelidine > 6-nitroquipazine. The growth of subcutaneous, PC-3 xenografts in athymic nude mice was significantly inhibited by fluoxetine. These results implicate biogenic amines such as serotonin in the growth of prostate carcinoma cells and indicate the potential use of serotonin-uptake inhibitors for the treatment of prostate cancer.
Electrical characterization of wafer level fan-out (WLFO) using film substrate for low cost millimeter wave application (2010)

In this paper, development of wafer level fan-out (WLFO) technology using ajinomoto build-up film (ABF) substrate with laser ablation process is introduced for low cost and high electrical performance for millimeter wave application. Wafer level fan-out (WLFO) technology using ABF substrate can enhance routing density and provide smaller form factor with lower parasitic elements than flip-chip chip scale packages (FCCSP). Moreover, short electrical paths from die out to package out can be realized with WLFO, and the low-k ABF material provides good electrical properties for high frequency areas. In this paper, the process of WLFO using ABF substrate with laser drilling is explained and electrical parasitic elements are compared between FCCSP and WLFO using 3D simulation tools. In addition, electrical characterization of coplanar waveguide (CPW) structure and interconnection models from die I/O pad to balls using 3D EM simulation are conducted to estimate effectiveness on millimeter wave range. Actual measurements of CPW structures are also presented.
Structure and photoluminescence of ZnSe nanoribbons grown by metal organic chemical vapor deposition (2004)

ZnSe nanoribbons have been synthesized using sputter-coated gold films as catalysts via metalorganic chemical vapor deposition on Si (100) substrates. Both x-ray and selected area electron diffractions determine that they have the zinc-blende structure. High-resolution transmission electron microscopic investigations show that their structure is highly ordered and contains coherent twin lamellae near one edge but is essentially free of dislocations. Photoluminescence studies at 10 K show that sharp excitonic peaks dominate their spectra, reflecting their high purity and nearly perfect stoichiometry. New excitonic peaks are observed in the nanoribbons and their possible origins are discussed.
A dielectric bifocal lens for multibeam antenna applications (1988)

An iteration technique is applied to the design of a bifocal dielectric lens antenna. A bifocal lens has two conjugate off-axis focal points and offers good off-axis scanning performance. A computer model was developed to aid in the design analysis and far-field performance evaluation of a bifocal lens. The computer simulation results demonstrate that the bifocal dielectric lens can provide a higher-gain radiation pattern for multibeam antenna (MBA) applications over a large field-of-view. The computer study also indicates that the quadratic phase error can be significantly reduced by constraining the feed along an optimized focal arc.< <ETX xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">></ETX>
Inherited Feature-based Similarity Measure based on large semantic hierarchy and large text corpus (1996)

We describe a similarity calculation model called IFSM (Inherited Feature Similarity Measure) between objects (words/concepts) based on their common and distinctive features. We propose an implementation method for obtaining features based on abstracted triples extracted from a large text corpus utilizing taxonomical knowledge. This model represents an integration of traditional methods, i.e., relation based similarity measure and distribution based similarity measure. An experiment, using our new concept abstraction method which we call the flat probability grouping method, over 80,000 surface triples, shows that the abstraction level of 3000 is a good basis for feature description.
Laterodorsal tegmental stimulation elicits dopamine efflux in the rat nucleus accumbens by activation of acetylcholine and glutamate receptors in the ventral tegmental area (2000)

Cholinergic and glutamatergic neurons in the laterodorsal tegmentum (LDT) and neighbouring mesopontine nuclei are thought to influence mesolimbic dopaminergic neuronal activity involved in goal-directed behaviours. We measured the changes in dopamine oxidation current (corresponding with dopamine efflux) in the nucleus accumbens (NAc) in response to electrical stimulation of the LDT using in vivo chronoamperometry in urethane-anaesthetized rats. LDT stimulation (35 Hz pulse trains for 60 s, 1 s intertrain interval) evoked a three-component change in dopamine efflux in the NAc: (i) an initial stimulation time-locked increase in the dopamine signal above baseline, followed by (ii) an immediate decrease below baseline, and thereafter by (iii) a prolonged increase in the dopamine signal above baseline. Intra-VTA infusion of the nicotinic receptor antagonist mecamylamine (5 microg/0.5 microL) or the ionotropic glutamate receptor antagonist kynurenate (10 microg/microL) attenuated the first LDT-elicited component. The second suppressive component was abolished by intra-LDT infusions of either the nonselective or the M2-selective muscarinic receptor antagonists scopolamine (100 microg/microL) and methoctramine (50 microg/microL), respectively. In contrast, intra-VTA infusions of scopolamine (200 microg/microL) resulted in a selective attenuation of the third facilitatory component, whereas both second and third components were abolished by systemic injections of scopolamine (5 mg/kg). These results suggest that the initial increase, subsequent decrease, and final prolonged increase in extracellular dopamine levels in the NAc are selectively mediated by LDT-elicited activation of (i) nicotinic and glutamatergic receptors in the VTA, (ii) muscarinic M2 autoreceptors on LDT cell bodies, and (iii) muscarinic receptors in the VTA, respectively.
Threshold-based load balancing in an ATM switch consisting of parallel output buffered switch elements (2002)

We consider an ATM switch consisting of a number of output buffered ATM switch elements operating in parallel. The architecture considered in the paper may lead to uneven distribution of cells over the parallel switch element buffers. We propose a threshold based load balancing method to evenly distribute cells over the parallel switch element buffers. We present details of how the load balancing method can be implemented. Computer simulations show that the proposed load balancing method significantly reduces the cell loss probability. We also present a queueing model of the number of cells in the switch buffers.
Evaluation of oriental medicinal herbs for estrogenic and antiproliferative activities (2006)

Herb extracts commercially used in Asia were screened for their estrogenic activity with a recombinant yeast system with both a human estrogen receptor (ER) expression plasmid and a reporter plasmid. Pueraria lobata (flower) had the highest estrogenic relative potency (RP, 17-estradiol = 1.00) (7.8e-3) (RP for + control), followed by Amomum xanthioides (1.3e-3), Glycyrrhiza uralensis, Zingiber officinale, Rheum palmatum, Curcuma aromatica, Eriobotrya japonica, Sophora flavescens, Anemarrhena asphodeloides, Polygonum multiflorum and Pueraria lobata (root) (9.5e-4-1.0e-4), and Prunus persica, Lycoppus lucidus and Adenophora stricta (9.0e-5-8.0e-5). In the antiproliferative assay, five human cancer cell lines representing different tissues (breast, lung and ovary) were used. Eriobotrya japonica showed strong cytotoxicity in ER-negative breast cancer (MDA-MB-231), cervix epitheloid (HeLa) and lung (A549) carcinoma cell lines.
Anion-effects on electrochemical properties of ionic liquid electrolytes for rechargeable aluminum batteries (2015)

Anion-effects are embodied in: (1) halogen anions resulting from different halogenated imidazole salt species, which is the critical factor for electrochemical windows; (2) aluminum chloride anions resulting from different AlCl<sub>3</sub>/imidazole salt mole ratios, which is the determinant of electrochemical activities.
Out-of-core rendering of massive geometric environments (2002)

We present an external memory algorithm for fast display of very large and complex geometric environments. We represent the model using a scene graph and employ different culling techniques for rendering acceleration. Our algorithm uses a parallel approach to render the scene as well as fetch objects from the disk in a synchronous manner. We present a novel prioritized prefetching technique that takes into account LOD-switching and visibility-based events between successive frames. We have applied our algorithm to large gigabyte sized environments that are composed of thousands of objects and tens of millions of polygons. The memory overhead of our algorithm is output sensitive and is typically tens of megabytes. In practice, our approach scales with the model sizes, and its rendering performance is comparable to that of an in-core algorithm.
Temperature‐Light Dual Control of Clouding Behavior of an Oligo(ethylene glycol)‐Diarylethene Hybrid System (2008)

A photochromic diarylethene derivative having hexa(ethylene glycol) side chains connected by an amide group was synthesized and the thermo- and the photoresponsive behavior was investigated. The cloud-point temperature was varied in a controlled manner over a range of 23 to 45 °C by irradiation with the appropriate wavelength of light (see figure).
Filament Winding Cylinders (1990)

A model was developed which describes the filament winding process of composite cylinders. The model relates the significant process variables such as winding speed, fiber tension, and applied temperature to the thermal, chemical and mechanical be havior of the composite cylinder and the mandrel. Based on the model, a user friendly code was written which can be used to calculate (1) the temperature in the cylinder and the mandrel, (2) the degree of cure and viscosity in the cylinder, (3) the fiber tensions and fiber positions, (4) the stresses and strains in the cylinder and in the mandrel, and (5) the void diameters in the cylinder.
Development of Yellow Seeded <i>Brassica napus</i> Through Interspecific Crosses (1994)

Abstract Yellow seeded Brassica napus was developed through interspecific crosses with the two mustard species, B. juncea and B. carinata. The objective of these two interspecific crosses was the introgression of genes for yellow seed colour from the A genome of B. juncea and C genome of B. carinata into the A and C genomes of B. napus , respectively. The interspecific F 1 generations were backcrossed to B. napus in an attempt to eliminate B genome chromosomes and to improve fertility. Backcross F 2 plants of the ( B. napus × B. juncea ) × B. napus cross were then crossed with backcross F 2 plants of the ( B. napus × B. carinata ) × B. napus cross. The objective of this intercrossing was to combine the A and C genome yellow seeded characteristics of the two backcross populations into one genotype. The F 2 generation of the backcross F 2 intercrosses was grown in the field, plants were individually harvested and visually rated for seed colour. Ninety‐one yellow seeded plants were identified among the 4858 plants inspected. This result indicated that the interspecific crossing scheme was successful in developing yellow seeded B. napus.
Asynchronous fast frequency-hopping CDMA cellular systems (1996)

We address the problem of constructing frequency-hopping codes for use in a fast frequency-hopping code-division multiple-access cellular system with a K-cell frequency-reuse scheme. Different hopping codes are used in different cochannel cells to reduce the cochannel interference. The frequency-hopping patterns possess ideal auto- and cross-correlation properties for use in the intracells and ideal autocorrelation and nearly ideal cross-correlation properties in the cochannel intercells. Additionally the cardinalities (the number of patterns) of the codes for use in the intracells meets the bound and hence are optimal. The maximum number of users which can be accommodated by using the proposed scheme is 20% more than the scheme using the same frequency-hopping code in all cells under a carrier-to-interference ratio of -15 dB.
