On the Numerical Approximation of the Bivariate Normal (Tetrachoric) Correlation Coefficient (1973)

In this paper a rapid and reliable method is found for estimating the value of the Bivariate Normal Correlation Coefficient, ρ, given values of the joint probability and the normal deviates, h and k , or the related areas. This technique finds useful application in the computational approximation of the tetrachoric correlation coefficient, r , when the underlying distributions may be assumed to be normal.

In situ Detection of a Single Bacterium in Complex Environment by Hyperspectral CARS Imaging (2016)

Abstract Detection of bacteria is essential for clinical diagnosis of infectious disease and food safety purposes. However, it is still a challenging task to rapidly detect bacteria, especially in their natural environment. By fiber‐laser based hyperspectral coherent anti‐Stokes Raman scattering (CARS) imaging, we showed that bacteria can be detected in a single cell level using spectral focusing in the C−H stretching region, with a total recording time of 1‐2 minutes. With phase retrieval and multivariate curve resolution analysis, we further showed that a single bacterium can be detected in complex environment such as milk and urine, without need of culturing, labelling, or sample contact. Our work promises hyperspectral CARS imaging to be a mobile and inexpensive setup for in situ detection of bacteria and bacterial activity studies.
Abdominal Water-Only T2 Estimation at 0.55T using a 3D Stack-of-Stars TSE-DIXON Technique (2023)

We explore the use of a stack-of-stars 3D TSE sequence along with multi-echo DIXON readouts for SNR-efficient, free-breathing water-only T2 estimation at 0.55T. A subspace constrained reconstruction is combined with a multi-step fat/ water separation algorithm to generate water-only T2-weighted images and T2 maps.
Behavior of particulate suspended droplet colliding to the liquid film flow on a rotating disk (2021)

The particle adhesion behavior on a rotating wafer during rotation cleaning was investigated experimentally. Acrylic plate with Si surface treatment was used as a test plate. A high-speed camera was set under the acrylic plate for recording the adhesion behavior of the particles. Adhesion rate was measured from the images captured by high-speed camera. As a result, it was confirmed that the particles adhered in proportion to time. Increasing rate of the number of adhered particles did not depend on the radial positions. Also, particle size did not depend on the adhesion characteristics. In addition, the behavior of dropped droplet containing the particles on the liquid film flow formed on the rotating plate was investigated. It was confirmed that the particles contained in the droplet adhered to the plate surface. This results suggested that the particles contained in the droplets were penetrated into the laminar sub-layer.
Matrix-Lifting Semi-Definite Programming for Detection in Multiple Antenna Systems (2010)

This paper presents a computationally efficient decoder for multiple antenna systems. The proposed algorithm can be used for any constellation (QAM or PSK) and any labeling method. The decoder is based on matrix-lifting semi-definite programming (SDP). The strength of the proposed method lies in a new relaxation approach applied to the previous work by Mobasher This results in a reduction of the number of variables from (NK + 1)(NK + 2)/2, in the previous work by Mobasher to (2N +K) <sup xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">2</sup> , in the new method, where N is twice the number of transmit antennas and K is the number of constellation points in each real dimension. It is shown that this reduction in the number of variables results in a significant computational complexity reduction compared to the previous work by Mobasher Moreover, the proposed method offers a better symbol error rate performance as compared to some known and recent SDP-based quasi-maximum likelihood detection methods reported in the literature.

Nature of Vanadium Species in Vanadium-Containing Silicalite and Their Behavior in Oxidative Dehydrogenation of Propane (1993)

V-containing silicalite samples prepared hydrothermally were characterized using a combination of physicochemical techniques and the activity of these silicalites in the oxidative dehydrogenation of propane using O2 and N2O was studied. FT-IR data on the mechanism of propane transformation in the presence of gaseous oxygen on these samples were also reported. The results indicate the presence of various types of vanadium species, and in particular, the formation of small amounts of a tetrahedral V5+ species stabilized in its configuration by interaction with the framework. This species probably forms at defect sites and is the more active and selective species in the oxidative dehydrogenation ot propane. Activated oxygen species generated by the interaction of O2 or N2O with reduced vanadium sites are suggested to be responsible for the selective transformation of propane to propylene. However, the good selectivity of this catalyst in propylene formation from propane is also connected to the type of chemisorption of the intermediate propylene on these tetrahedral V5+ sites and to the relative inertness towards its further transformation due to the specific coordination environment of vanadium. In particular, the data indicate that propylene is coordinatively adsorbed as a π-complex with the CH3 group interacting with a nearlying weakly basic silanol. Infrared darta suggest that the rate of formation of propylene from propane in the presence of O2 is higher than the rate of its consecutive transformation to surface oligomers or acrolein and acrylic acid, probably intermediates to aromatics and COx, respectively. The model of the coordination environment and the peculiar characteristics of these tetrahedral V5+ sites in the silicalite in relation to their selective behavior in propane oxidative dehydrogenation are discussed.
Conditional Control of CRISPR/Cas9 Function (2016)

The recently discovered CRISPR/Cas9 endonuclease system, comprised of a guide RNA for the recognition of a DNA target and the Cas9 nuclease protein for binding and processing the target, has been extensively studied and has been widely applied in genome editing, synthetic biology, and transcriptional modulation in cells and animals. Toward more precise genomic modification and further expansion of the CRISPR/Cas9 system as a spatiotemporally controlled gene regulatory system, several approaches of conditional activation of Cas9 function using small molecules and light have recently been developed. These methods have led to improvements in the genome editing specificity of the CRISPR/Cas9 system and enabled its activation with temporal and spatial precision.
Controlled single-electron effects in nonoverlapped ultra-short silicon field effect transistors (2003)

Low temperature transport measurements in ultra-short silicon field effect transistors with deliberately nonoverlapping gates show periodic Coulomb blockade oscillations. Despite its relatively small charging energy (/spl ap/2 meV) this single-electron effect is promising because it is controlled by geometrical confinement between the nonoverlapped extensions acting as tunnel barriers. Remarkably these single electron devices are excellent field effect transistors at room temperature.
A Virtual SDN-Enabled LTE EPC Architecture: A Case Study for S-/P-Gateways Functions (2013)

The recent initiative of Network Functions Virtualization (NFV) aims to deliver any data- plane processing or control-plane function in high volume data centers or network elements to decrease operational cost and increase deployment flexibility. In order to dynamically direct traffic flows between respective network elements, Software Defined Networking (SDN) can be seen as one enabler. In this paper, we focus on mobile core network nodes such as the MME, HSS, S- and P- Gateway as standardized for the LTE Evolved Packet Core (EPC). One straightforward solution for a virtualized EPC architecture would be to move all EPC network nodes completely into a data center and handle the data traffic via SDN-enabled switches. However, this solution would keep the conventional monolithic architecture unchanged. A possible split in the EPC functionality between a centralized data center and operator's transport network elements could be needed to provide the desired flexibility, performance and TCO reduction. Therefore, we have analyzed the EPC nodes and classified their functions according to their impact on data-plane and control-plane processing. We propose a mapping for these functions on four alternative deployment frameworks based on SDN and OpenFlow (OF). In addition, we investigate the current OF implementation's capability to realize basic core operations such as QoS, data classification, tunneling and charging. Our analysis shows that functions, which involve high data packet processing such as tunneling, have more potential to be kept on the data-plane network element, i.e. realized by an OpenFlow Switch. We argue for an enhanced OF network element NE+, which contains additional network functions next to the basic OpenFlow protocol.
Dephosphorylation of the Cadherin-associated p100/p120 Proteins in Response to Activation of Protein Kinase C in Epithelial Cells (1997)

Protein kinase C signaling pathways have been implicated in the disruption of intercellular junctions, but mechanisms are not clear. p100 and p120 are members of the Armadillo family of proteins and are localized to cellular adherens junctions. In strain I Madin-Darby canine kidney cells, protein kinase C activation leads to disruption of tight junctions and an increase in permeability of cell monolayers. We show that this permeability increase is accompanied by dephosphorylation of p100/p120 on serine and threonine residues. The dephosphorylation of these proteins can also be induced by the kinase inhibitors staurosporine, KT5926, and Gö 6976. Treatment of cells with phosphatase inhibitors induced hyperphosphorylation of p100 and p120. Thus, p100 and p120 participate in a regulatable cycle of serine/threonine phosphorylation and dephosphorylation. Protein kinase C must act, directly or indirectly, by perturbing this phosphorylation cycle, by inhibition of a p100/p120 kinase and/or activation of a phosphatase. These data clearly show that p100 and p120 are targets of a novel protein kinase C signaling pathway. Dephosphorylation of these proteins precedes the permeability increase across epithelial cell monolayers seen in response to phorbol esters, raising the possibility that this pathway may play a role in the modulation of intercellular junctions.
Alu sequences transcription inX. laevisoocytes: nuclear-cytoplasmic partitioning and evidence for 3′ end processing reactions (1985)

A large Alu-family cluster in the 5' flanking region of a human alpha 1-acid glycoprotein gene has been identified and sequenced. Individual members microinjected into X. laevis oocytes are transcribed only when canonical box A and B components of the split pol III promoter are present. Alu transcripts accumulate in the nucleus. An unusually short Alu transcript, able to assume a stable secondary structure, undergoes a 3' end processing reaction similar to the one required for tRNA 3' end maturation.
A generalization of some policing mechanisms (1992)

The authors highlight the fact that most of the policing schemes proposed in the literature neglect important information on the past cell blocking behavior of the policing mechanism. They propose a modification of these schemes in which the discarded cell information is used, with almost no overhead compared to the usual strategies. The behavior of the modified policing mechanisms is discussed. This new behavior is illustrated by using the generalized leaky bucket to police the mean rate of a source. Analysis using an on/off input process shows that the modified versions detect smaller-magnitude abuses, police the sources closer to their declared resources utilization, and have a faster response time. Results are presented showing that the generalized sliding window exhibits the same kind of behavior.< <ETX xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">&gt;</ETX>
Effects of concentration and clusters in erbium-doped fiber lasers (1993)

We report a low-threshold, high-conversion-efficiency erbium-doped fiber laser in a 100-parts-in-106 fiber pumped at 1.48 μm. The threshold and efficiency are found to deteriorate noticeably as the erbium concentration is increased. We propose that this is due mostly to rapid cross relaxation between ion pairs or clusters, and through modeling we show that the cluster content increases with concentration.
Porous Organic Polymers: Distinction from Disorder? (2010)

An alternative explanation: The new microporous organic polymer framework PAF-1 displays exceptional physicochemical stability along with an extremely high surface area (BET surface area 5640 m2 g−1). The question arises whether this material displays the high degree of crystalline order presumed necessary for this high surface area.
The Molecular Mechanism of P2Y1Receptor Activation (2016)

Abstract Human purinergic G protein‐coupled receptor P2Y 1 (P2Y 1 R) is activated by adenosine 5′‐diphosphate (ADP) to induce platelet activation and thereby serves as an important antithrombotic drug target. Crystal structures of P2Y 1 R revealed that one ligand (MRS2500) binds to the extracellular vestibule of this GPCR, whereas another (BPTU) occupies the surface between transmembrane (TM) helices TM2 and TM3. We introduced a total of 20 μs all‐atom long‐timescale molecular dynamic (MD) simulations to inquire why two molecules in completely different locations both serve as antagonists while ADP activates the receptor. Our results indicate that BPTU acts as an antagonist by stabilizing extracellular helix bundles leading to an increase of the lipid order, whereas MRS2500 blocks signaling by occupying the ligand binding site. Both antagonists stabilize an ionic lock within the receptor. However, binding of ADP breaks this ionic lock, forming a continuous water channel that leads to P2Y 1 R activation.
A 2-D Microcantilever Array for Multiplexed Biomolecular Analysis (2004)

An accurate, rapid, and quantitative method for analyzing variety of biomolecules, such as DNA and proteins, is necessary in many biomedical applications and could help address several scientific issues in molecular biology. Recent experiments have shown that when specific biological reactions occur on one surface of a microcantilever beam, the resulting changes in surface stress deflect the cantilever beam. To exploit this phenomenon for high-throughput label-free biomolecular analysis, we have developed a chip containing a two-dimensional (2-D) array of silicon nitride cantilevers with a thin gold coating on one surface. Integration of microfluid cells on the chip allows for individual functionalization of each cantilever of the array, which is designed to respond specifically to a target analyte. An optical system to readout deflections of multiple cantilevers was also developed. The cantilevers exhibited thermomechanical sensitivity with a standard deviation of seven percent, and were found to fall into two categories-those whose deflections tracked each other in response to external stimuli, and those whose did not due to drift. The best performance of two "tracking" cantilevers showed a maximum difference of 4 nm in their deflections. Although "nontracking" cantilevers exhibited large differences in their drift behavior, an upper bound of their time-dependent drift was determined, which could allow for rapid bioassays. Using the differential deflection signal between tracking cantilevers, immobilization of 25mer thiolated single-stranded DNA (ssDNA) on gold surfaces produced repeatable deflections of 80 nm or so on 0.5-/spl mu/m-thick and 200-/spl mu/m-long cantilevers.

Aqueous polyolefin dispersion for packaging boards and papers (2011)

Various types of polyolefins are used in many industrial applications due to the combination of attractive performance attributes they offer. Extrusion coating has traditionally been the main technology for achieving relatively thin polyolefin coatings on a moving web. Recently Dow introduced aqueous dispersions of polyolefins. The dispersions are produced by a proprietary mechanical dispersion technology. The delivery of polyolefins in a water-based dispersion enables the use of a variety of new coating application techniques available today for water or solvent borne systems. The delivery of polyolefins as aqueous dispersions introduces polyolefins into new application areas where current emulsions and binders are limited by their performance and where extrusion coating cannot be used or may not the most efficient coating method. Aqueous dispersions of polyolefins offer the characteristics of polyolefins such as chemical resistance, thermoform ability, recyclability and adhesion to polyolefins in combination with a waterborne fabrication advantage. This presentation introduces the aqueous polyolefin dispersion technology with examples of application areas for the packaging industry where aqueous polyolefin dispersions provide synergies as well as new opportunities beyond extrusion coating of polyolefins.
Bragg gratings in defect-free germanium-doped optical fibers (1999)

Bragg gratings have been written in germanium-doped optical fibers that have been treated to remove the UV absorption bands associated with oxygen-deficient defects. When one is using high-intensity 193-nm light from an ArF excimer laser to fabricate the gratings, the refractive index increases and the grating transmission spectra are similar to those obtained in standard (untreated) fiber.
On the Reactivity of 1H‐Pyrazino[2,3‐c][1,2,6]thiadiazine 2,2‐Dioxide and Derivatives: Nucleophilic Substitution, Amination, Aldol‐Type Condensation, Oxidation, and Hydrolysis (2003)

Abstract The reactivity of the 1 H ‐pyrazino[2,3‐ c ][1,2,6]thiadiazine 2,2‐dioxide system, structurally related to pteridine, was studied, and a number of novel derivatives were synthesized. The chemical behaviors of these two related fused polyaza systems were compared.
