Prediction of flow induced sound generated by cross flow past finite length circular cylinders (2018)

The paper presents aeroacoustic results for the flow around finite-length circular cylinders at Reynolds number 84 770 for various length-to-diameter (L/D) ratios (= 3, 9, 20, 25, 30, and 35). The incompressible Navier-Stokes equations are solved using the large eddy simulation model of turbulence followed by acoustic predictions in the far field using Ffwocs Williams and Hawkings method. The comparisons of numerical and anechoic wind tunnel measurements show good agreement in terms of the aerodynamic forces and acoustic parameters such as tonal frequency, tonal sound pressure level, and overall sound pressure level. The cylinder L/D ratio was observed to be a significant parameter that controls vortex shedding and consequently the flow induced sound generation.
Development of a GC/Quadrupole-Orbitrap Mass Spectrometer, Part II: New Approaches for Discovery Metabolomics (2014)

Identification of unknown peaks in gas chromatography/mass spectrometry (GC/MS)-based discovery metabolomics is challenging, and remains necessary to permit discovery of novel or unexpected metabolites that may elucidate disease processes and/or further our understanding of how genotypes relate to phenotypes. Here, we introduce two new technologies and an analytical workflow that can facilitate the identification of unknown peaks. First, we report on a GC/Quadrupole-Orbitrap mass spectrometer that provides high mass accuracy, high resolution, and high sensitivity analyte detection. Second, with an "intelligent" data-dependent algorithm, termed molecular-ion directed acquisition (MIDA), we maximize the information content generated from unsupervised tandem MS (MS/MS) and selected ion monitoring (SIM) by directing the MS to target the ions of greatest information content, that is, the most-intact ionic species. We combine these technologies with (13)C- and (15)N-metabolic labeling, multiple derivatization and ionization types, and heuristic filtering of candidate elemental compositions to achieve (1) MS/MS spectra of nearly all intact ion species for structural elucidation, (2) knowledge of carbon and nitrogen atom content for every ion in MS and MS/MS spectra, (3) relative quantification between alternatively labeled samples, and (4) unambiguous annotation of elemental composition.
Wireless physiological monitoring and ocular tracking: 3D calibration in a fully-immersive virtual health care environment (2010)

Wireless physiological/neurological monitoring in virtual reality (VR) offers a unique opportunity for unobtrusively quantifying human responses to precisely controlled and readily modulated VR representations of health care environments. Here we present such a wireless, light-weight head-mounted system for measuring electrooculogram (EOG) and electroencephalogram (EEG) activity in human subjects interacting with and navigating in the Calit2 StarCAVE, a five-sided immersive 3-D visualization VR environment. The system can be easily expanded to include other measurements, such as cardiac activity and galvanic skin responses. We demonstrate the capacity of the system to track focus of gaze in 3-D and report a novel calibration procedure for estimating eye movements from responses to the presentation of a set of dynamic visual cues in the StarCAVE. We discuss cyber and clinical applications that include a 3-D cursor for visual navigation in VR interactive environments, and the monitoring of neurological and ocular dysfunction in vision/attention disorders.

Tunneled Inter-domain Routing (TIDR) (2006)

In this paper we propose a new hierarchical method to enhance the
current routing and forwarding paradigm for the Internet called
Tunneled Inter-Domain Routing (TIDR). We will present the way in which
TIDR permits to establish tunnels to the edge of the network, and how
they will be used to forward traffic to stub networks. These tunnels
will be explicitly signaled by using a new transitive BGP attribute
called LOCATOR. This new routing and forwarding paradigm provides,
among others, the following benefits: global routing table reduction,
inter-domain routing infrastructure protection, improved multi-homing
of edge networks, numerous forwarding decisions for a particular
address prefix, it stops the AS number consumption, and it can be
smoothly deployed.
Highly Efficient Palladium‐Catalyzed Allylic Alkylation of Cyanoacetamides with Controllable and Chemoselective Mono‐ and Double Substitutions (2016)

Abstract It was found that catalytic allylation of various cyanoacetamides proceeded smoothly and efficiently in environmentally benign PEG‐400 (PEG=poly(ethylene glycol)) in the presence of Pd(OAc) 2 and novel triazine‐derived multifunctional ligand L1 , with which this reaction could afford the structurally diverse mono‐ and double allylated adducts in good to excellent yields as well as good chemo‐ and regioselectivity. In addition, this Pd/ L1 /PEG‐400 catalyst system could be recycled for five runs with good yield and high efficiency, which supported the notion that the triazine‐containing Schiff base based phosphine ligand could be a multifunctional and reusable ligand encapsulated in PEG‐400.
An apparatus for studying the laws of the magnetic field due to an electric current in a long straight conductor (1951)

It is impracticable to measure directly the magnetic field due to an electric current in a single long straight conductor, since a complete circuit is necessary. By using a narrow rectangular coil the field is, within reasonable limits of accuracy, the same as that due to the two long sides regarded as infinite in length. The formulae for the field are simple for points along two axes relative to the coil, provided the points are not too far removed from its centre. The linearity of suitable graphs of a series of observations constitutes a verification of the law derived for a single straight conductor, and from the graphs values of the horizontal component of the earth's magnetic field can be determined. Two experimental methods, involving the location of neutral points, are described.
Optimally Directed Shape Generation by Shape Annealing (1993)

The new design technique of shape annealing is introduced. Shape annealing is a variation of the simulated annealing stochastic optimization technique. It produces optimally directed shapes within the language specified by a shape grammar. It does so by controlling the selection and application of shape rules such that superior shapes evolve as the algorithm progresses.
Real-time low-complexity adaptive approach for enhanced QoS and error resilience in MPEG-2 video transport over RTP networks (2005)

In this paper, the problems of redundancy allocation for providing effective error-resilience and service class distribution for enhanced quality of service (QoS) in real-time MPEG-2 video transport are addressed. A real-time low-complexity content-based adaptive error-resilient approach is proposed for the transport of MPEG-2 video streams, encapsulated using real-time transport protocol (RTP) and delivered over heterogeneous networks. An algorithm is derived using spatial and temporal properties of MPEG-2 video for assigning weights to each packet based on the estimated perceptual error. These weights, which indicate the relative importance of RTP packets, together with the communication channel characteristics are used to determine the allocation of resources for providing improved error-resilience and for assigning data packets to various classes of service in order to enhance the quality of transmission. Parameters extracted from the RTP header are used to determine the weights, so that the proposed algorithm can be implemented in real-time. This algorithm is used for adaptively allocating redundant forward error correction packets as well as for marking and forwarding of RTP packets in differentiated services (DiffServ). Simulation results are presented to show the significant improvement in performance based on our proposed approach to video transport.
Structure and regulation of the SSA4 HSP70 gene of Saccharomyces cerevisiae. (1990)

SSA4 is the only one of five heat-inducible HSP70 genes in Saccharomyces cerevisiae whose expression is restricted to conditions of stress. Comparison of the nucleotide sequences of the SSA4 gene with other HSP70 genes indicates that it diverged from its most closely related yeast homologues hundreds of millions of years ago. However, a high degree of identity has been maintained between Ssa4p and other yeast 70-kDa heat-shock proteins at the amino acid level suggesting, in light of its distinct pattern of regulation, that it performs an important function. A 44-base pair region of the SSA4 promoter containing an extended match to the conserved eukaryotic heat-shock element (HSE) is necessary and sufficient to mediate heat-inducible regulation. HSESSA4 is capable of promoting only a low level of transcription under nonstress conditions. We present evidence in support of a revised definition of the functional HSE in S. cerevisiae, similar to the recently proposed modular Drosophila HSE. Elevated expression of several heat-shock proteins in an ssa1ssa2 double-mutant strain has previously been reported. The SSA4 promoter is activated in this strain. The increase in expression of SSA4 caused by deletion of these closely related genes is mediated via the same upstream activating sequences that activate transcription in response to heat shock. Activation of HSE-mediated transcription by disruption of constitutively expressed HSP70 genes supports an autoregulatory model of control of the heat-shock response.
A Practical Approach to Optical Cross-Reactive Sensor Arrays (2010)

Supramolecular analytical chemistry has emerged as a new discipline at the interface of supramolecular and analytical chemistry. It focuses on analytical applications of molecular recognition and self-assembly. One of the important outcomes of the supramolecular analytical chemistry is the understanding of molecular aspects of sensor design, synthesis and binding studies of sensors while using rigorous methods of analytical chemistry as a touchstone to verify the viability of the supramolecular aspects of the sensor design. This critical review provides a simplified version of the chemometric procedures involved in realizing a successful analytical experiment that utilizes cross-reactive optical sensor arrays, and summarizes the current research in this field. This review also shows several examples of use of described chemometric methods for evaluation of chemosensors and sensor arrays. Thus, this review is aimed mostly at the readers who want to test their newly-developed chemosensors in cross-reactive arrays (169 references).
Catalytic Deoxygenation of Tall Oil Fatty Acid over Palladium Supported on Mesoporous Carbon (2011)

Catalytic deoxygenation of tall oil fatty acids (TOFAs) was investigated over 1 wt % Pd/C Sibunit, which is a synthetic mesoporous carbon. The reactions were performed in a semi-batch reactor using dodecane as a solvent under 17 bar of total pressure. The main studied parameters were the reaction temperature, initial concentration of TOFA, effect of the reaction atmosphere, and metal loading. The temperature and initial concentration ranges were 300–350 °C and 0.15–0.6 mol/L, respectively. The total conversion of fatty acids increased, as expected, with increasing temperatures and decreasing initial TOFA concentrations. The main liquid-phase products were n-heptadecane and n-heptadecene. In addition to the desired linear C17 hydrocarbons, also aromatic C17 compounds, such as undecylbenzene, were formed. The best conditions for the formation of the desired C17 hydrocarbons were lower initial concentrations of TOFA, 300–325 °C, and the presence of hydrogen. An increase of the metal loading (4 wt %) led to an increase of the selectivity to linear C17 hydrocarbons.
How a robot should give advice (2013)

With advances in robotics, robots can give advice and help using natural language. The field of HRI, however, has not yet developed a communication strategy for giving advice effectively. Drawing on literature in politeness and informal speech, we propose options for a robot's help-giving speech-using hedges or discourse markers, both of which can mitigate the commanding tone implied in direct statements of advice. To test these options, we experimentally compared two help-giving strategies depicted in videos of human and robot helpers. We found that when robot and human helpers used a hedge or discourse markers, they seemed more considerate and likeable, and less controlling. The robot that used discourse markers had even more impact than the human helper. The findings suggest that communication strategies derived from speech used when people help each other in natural settings can be effective for planning the help dialogues of robotic assistants.
Digest making method based on turning point analysis (2005)

A huge amount of multimedia content is available in the current Web environment. Streaming of video programs has become one of the popular Web-based information services. Automatic digest generation is an important application using video program streams. We have developed a digest making method called PDMS (Personal Digest Making Scheme). PDMS extracts significant scenes and constructs digests automatically using the video program meta data. In PDMS, only a successful play event such as a goal scored was considered significant, and a misplay event, such as a shot that did not score was not taken into account, although such an event may affect the game progress. This paper introduces a new concept of turning point analysis into PDMS. The turning point analysis is based on a winning probability for a sports programs. The winning probability indicates the probability of a home team beating an away team at the end of the game, given the current score and the time elapsed since the beginning of the game. Using the winning probability, we can more precisely evaluate the significance of each event, not merely a successful play but also a misplay. This paper presents turning point analysis for a soccer match. It also gives evaluation results of this extended PDMS, including turning point analysis for a recently broadcasted professional soccer match.

Reduced intracellular pH in the basal ganglia and whole brain measured by <sup>31</sup>P‐MRS in bipolar disorder (2003)

The authors have previously reported that intracellular pH measured by phosphorus-31 magnetic resonance spectroscopy (31P-MRS) was decreased in the frontal lobes of patients with bipolar disorder. In the present study, phosphorus metabolism in the basal ganglia was examined in 13 patients with bipolar disorder and 10 matched controls by localized 31P-MRS. While no significant alteration of peak area ratios was found for all phosphorus metabolites, intracellular pH was significantly reduced in the basal ganglia in patients with bipolar disorder (7.014 +/- 0.045) compared with control subjects (7.066 +/- 0.047, P < 0.05). Unexpectedly, non-localized 31P-MR spectra also showed significantly lower levels of intracellular pH (6.970 +/- 0.025) than controls (6.986 +/- 0.024, P < 0.05). These results suggest that decreased intracellular pH in the brain of patients with bipolar disorder is not caused by dysfunction of the frontal lobes but reflect altered metabolism at the cellular level.
CHARACTERIZATION OF A GENE ENCODING THE LIGHT‐HARVESTING VIOLAXANTHIN‐CHLOROPHYLL PROTEIN OF <i>NANNOCHLOROPSIS</i> SP. (EUSTIGMATOPHYCEAE) (2000)

In contrast to vascular plants, green algae, and diatoms, the major light-harvesting complex of the marine eustigmatophyte genus Nannochloropsis is a violaxanthin-chlorophyll a protein complex that lacks chlorophylls b and c. The isolation of a single polypeptide from the light-harvesting complex of Nannochloropsis sp. (IOLR strain) was previously reported (Sukenik et al. 1992). The NH<sub>2</sub> -terminal amino acid sequence of this polypeptide was significantly similar to NH<sub>2</sub> -terminal sequences of the light-harvesting fucoxanthin, chlorophyll a/c polypeptides from the diatom Phaeodactylum tricornutum Bohlin. Using polyclonal antibodies raised to the Nannochloropsis light-harvesting polypeptide, a gene encoding this polypeptide was isolated from a cDNA expression library. The deduced amino acid sequence of the Nannochloropsis violaxanthin-chlorophyll a polypeptide reveals a 36 amino acid presequence followed by 173 amino acids that constitute the mature polypeptide. The mature polypeptide has 30%-40% sequence identity to the diatom fucoxanthin-chlorophyll a/c polypeptides and less then 27% identity to the green algal and vascular plant light-harvesting chlorophyll polypeptides that bind both chlorophylls a and b. Its molecular mass, as deduced from the gene sequence, is 18.4 kDa with three putative transmembrane helices and several residues that may be involved in chlorophyll binding. The cDNA encoding the violaxanthin-chlorophyll a polypeptide was used to isolate and characterize a 10 kb genomic fragment containing the entire gene. The open reading frame was interrupted by five introns ranging in size from 123 to 449 bp. The intron borders have typical eukaryotic GT … AG sequences.
Communication—Investigation of Anatase-TiO<sub>2</sub>as an Efficient Electrode Material for Magnesium-Ion Batteries (2016)

Magnesium-ion batteries (MIBs) have twofold volumetric energy density than that of lithium without the dendritic deposition morphology associated with Li, which makes MIBs attractive options. We investigate the feasibility of using anatase-phase TiO2 as an electrode material for MIBs. Electrochemical, microscopic, and spectroscopic analyses are performed in order to probe Mg-ion insertion as well as determine the limitation of TiO2 as a viable electrode material.
Improved Kelvin probe force microscopy for imaging individual DNA molecules on insulating surfaces (2010)

Electrostatic forces and potentials are keys in determining the interactions between biomolecules. We have recently imaged the topography and electrostatic surface potential of nucleic acid molecules on silicon surfaces using Kelvin probe force microscopy (KPFM). Here, we demonstrate KPFM imaging on insulating surfaces like mica, which provides access to configurations of DNA that are projections of its structure in solution. In particular, we apply dual-frequency mode to minimize the tip-sample distance at which the Kelvin probe signal is acquired and use the fundamental resonance of the cantilever to determine surface potential and its first overtone to detect the topography.
Invited paper A unified theory for MOS circuit design—switching network logic (1985)

ABSTRACT The switching network logic (SNL) design method is introduced. It is a systematic approach to the design of MOS circuits based on the switching network concept. The double-rail SNL and single-rail SNL are discussed in which the single-rail SNL makes efficient use of the negation property of MOS circuits. The SNL circuits have better performances than those of MOS circuits designed with NAND-NOR-gate or negative-gate approaches. Moreover, the SNL circuit is guaranteed to be minimal for SC and SP functions.
Electron Decoupling with Dynamic Nuclear Polarization in Rotating Solids (2017)

Dynamic nuclear polarization (DNP) can enhance NMR sensitivity by orders of magnitude by transferring spin polarization from electron paramagnetic resonance (EPR) to NMR. However, paramagnetic DNP polarizing agents can have deleterious effects on NMR signals. Electron spin decoupling can mitigate these paramagnetic relaxation effects. We demonstrate electron decoupling experiments in conjunction with DNP and magic-angle-spinning NMR spectroscopy. Following a DNP and spin diffusion period, the microwave irradiation frequency is quickly tuned on-resonance with electrons on the DNP polarizing agent. The electron decoupling performance shows a strong dependence on the microwave frequency and DNP polarization time. Microwave frequency sweeps through the EPR line shape are shown as a time domain strategy to significantly improve electron decoupling. For <sup>13</sup>C spins on biomolecules frozen in a glassy matrix, electron decoupling reduces the line widths by 11% (47 Hz) and increases the intensity by 14%.
Aluminum‐27 and Silicon‐29 Magic‐Angle Spinning Nuclear Magnetic Resonance Study of the Kaolinite‐Mullite Transformation (1988)

The 27 Al and 29 Si magic‐angle spinning nuclear magnetic resonance (MAS‐NMR) study of the kaolinite‐mullite transformation has shown the presence of Al in tetra‐ and pentacoordination in dehydroxylated kaolinite. The 29 Si NMR signal analysis of samples heated above 400°C demonstrates that the tetrahedral sheet of kaolinite begins to break down near 600°C and continues to do so to 900°C. From the 27 Al NMR signal evolution, it can be deduced that the exothermic peak at 980°C in DTA curves is associated with the modification of the coordination of Al, which changes from the tetra‐ or pentacoordination to the more stable octahedral coordination. Heating the sample at 880°C for 36 h produces the same transformation in the coordination of Al ions and the elimination of the exothermic peak at 980°C in the DTA diagram. After this transformation, all spectra show two tetrahedral lines characteristic of mullite, indicating that nuclei of mullite with low crystallinity are generated during the exothermic process which are not detected by XRD. At higher temperatures tetrahedral NMR peaks increase in intensity, yielding, at 1200°C, the 3:2 mullite NMR spectrum.
