Strategies and data analysis techniques for lipid and phospholipid chemistry elucidation by intact cell MALDI-FTMS (2004)

Ions attributed to lipids and phospholipids are directly observed by desorption from whole bacteria using intact cell (IC) matrix-assisted laser desorption-ionization (MALDI) Fourier transform mass spectrometry (FTMS). Saccharomyces cerevisiae are grown in rich media broth, concentrated, and applied directly to the MALDI surface without lysis or chemical treatment. FTMS of MALDI ions gives excellent signal to noise ratios with typical resolving powers of 90,000 and mass precision better than 0.002 Da. Use of accurate mass measurements and a simple set of rules allow assignment of major peaks into one of twelve expected lipid classes. Subsequently, fractional mass versus whole number mass plots are employed to enhance visual interpretation of the high-resolution data and to facilitate detection of related ions such as those representing homologous series or different degrees of unsaturation. This approach, coupled with rules based on bacterial biochemistry, is used to classify ions with m/z up to about 1000. Major spectral peaks in the range m/z 200-1000 are assigned as lipids and phospholipids. In this study, it is assumed that biologically-derived ions with m/z values lower than 1000 are lipids. This is not unreasonable in view of the facts that molecular weights of lipids are almost always less than 1000 Da, that the copy numbers for lipids in a cell are higher than those for any single protein or other component, and that lipids are generally collections of distinct homologous partners, unlike proteins or other cell components. This paper presents a new rapid lipid-profiling method based on IC MALDI-FTMS.
Fast 3D face modeling using mesh optimization and vertex integration (2005)

3D animation is a field in computer graphics with vibrant recent research activities, and one of the important research areas in 3D animation is animating the human being. Animation production using 3D faces has traditionally involved the animator conducting frame-by-frame manual work, requiring much effort, time, equipment and 3D software. This paper describes the implementation process of creating a fast and simple 3D face model that resembles the actual human face by inputting the frontal facial image, and suggests a technique for simplifying the mesh data of the general 3D model.
Optimization of selenium determination in chicken's meat and eggs by the hydride-generation atomic absorption spectrometry method (2008)

Effect of selenium-enriched feed on the selenium content of chicken meat and eggs was investigated. Selenium was determined by hydride-generation atomic absorption spectrometry (HG-AAS). The effect of digestion procedures on the determination was also studied. Optimum values of the variables applied for the HG-AAS method, such as HCl and NaBH(4) concentration, and the flow rate of carrier gas were determined experimentally. Analytical parameters such as the selectivity, accuracy, precision, sensitivity, limit of detection and limit of quantification were also determined. The limit of detection and the limit of quantification were 0.78 microg/l and 2.35 microg/l, respectively. The effect of interfering elements that are possibly present in the samples analyzed on the recovery of selenium was also investigated. The measurements were validated using diverse types of certified reference materials (IRMM IMEP 19, LGC 7160 and GBW 08572) and by a method of yield measurement of calibration solution addition in mineralized samples. The accuracy and precision of the method are satisfactory and the relative standard deviation is less than 4%, and the relative error is less than 10% for a 500 microl sample containing 10 microg/l selenium. It was observed that the selenium content of chicken meat and eggs obtained from the chickens nourished with fortified feed was higher than those without fortified feed.
Comparison of theories for the translational and rotational diffusion coefficients of rod-like macromolecules. Application to short DNA fragments (1984)

Two theories relating the translational and rotational diffusion coefficients Dt and Dr of a rod-like macromolecule to its length and diameter, proposed by Broersma [J. Chem. Phys. 74, 6989 (1981)], and Tirado and García de la Torre [J. Chem. Phys. 71, 2581 (1979); 73, 1986 (1980)] are shown to predict different values of the coefficients for a particle of given dimensions. Next, we use the two theories to analyze existing experimental data of sedimentation coefficients s and translational and rotational diffusion coefficients of short DNA fragments, and obtain values of the hydrated diameter of DNA d which is treated as an adjustable parameter. The results are compared with the expected value, d≂26Å. This comparison favors clearly the Tirado–Garcia de la Torre theory in the case of Dt and s. For Dr, and using a rise per base pair r=3.4 Å, this theory gives best agreement for all the data examined, while when r=3.3 Å, the agreement depends on the source of data.

XIII. On the apparent direction of eyes in a portrait (1824)

Abstract It may seem, at first view, that portrait painting is not altogether a fit subject to be brought before the Royal Society, since the delicate touches by which the skill and feeling of an accomplished artist convey an expression of sense, and grace, and sensibility to the finished representation of the human form, cannot admit of such strict analysis as the ordinary subjects of our inquiry. Nevertheless, since the rules of perspective, which are strictly mathematical, are perfectly within our province, it may be presumed that a question, in which some principles of that science are involved, may be considered a legitimate subject of communication ; that effects not anticipated on any received principles must deserve attention; and that the explanation of them will be found to have some pretensions to utility.
A photon-counting optical communication system for underwater data transfer (2012)

We report on the performance of a photon-counting optical communication system which was used to transmit optical data at clock rates (not detection rates) of 40Mb/s at a wavelength of 450nm. The transmitted test data patterns comprised of one page of ASCII text preceded by a pseudo-random sequence used as a timing reference pattern by the receiver. The optical data patterns were transmitted through an aquarium tank containing ~110 litres of water and were detected at the receiver by a shallow junction silicon single photon avalanche diode detector. An antacid, brand name Maalox, was introduced into the tank to increase the scattering of the optical pulses. The bit error rate and bit rate of the transmitted data were investigated for a range of Maalox concentrations. The optical attenuation and pulse distortion caused by the introduction of Maalox was also investigated.

Effects of dopings on the electric-field-induced atomic migration and void formation in Ge<inf>2</inf>Sb<inf>2</inf>Te<inf>5</inf> (2011)

In the electomigration of molten GST, the effects of N-and Bi-doping on the electromigration were aslo studied to find the solution for inhibiting the electromigration. When a single pulse (~10 <sup xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">-3</sup> s) was applied to the lines, both undoped and doped GST lines were melted by Joule heating, and Ge and Sb atoms migrate to the cathode, whereas Te atoms migrate to the anode. This elemental separation in the molten GST was caused by an electrostatic force-induced electromigration. The migration rate of the constituent atoms in the undoped GST was similar to that in Bi-doped GST, but was decreased by N-doping. Under applying a 10 MHz pulsed DC, the melting by Joule heating was inhibited, and electromigration in the crystalline state was detected. All constituent elements migrated to the cathode, which is originated from the electromigration by hole-windforce. This study provide the basic understanding about the degradation phenomena in phase change memory, and suggest the method for inhibiting the endurance failures.
The association of HLA‐linked genes with systemic lupus erythematosus (1986)

The reported associations between HLA antigen DR3 and null (QO) alleles at the C4A and C4B loci and systemic lupus erythematosus are here analysed. The empirical logistic method has been applied to a body of data which included the relevant genotypes. The analysis suggests that the association with null alleles at the C4 loci is primary and the DR3 association is likely to be secondary to this. This may give information as to the location of the HLA-linked disease susceptibility gene.
Literary Theory and Medieval Texts: Authority and the Worldly Power of Language in "El Conde Lucanor" (1991)

One of the more serious challenges to traditional methodologies employed in the study of medieval Hispanic literature has come from recent developments in literary theory, in particular, theories of textuality. This challenge consists in part of a revision of assumptions regarding the value and importance or even the meaning and nature of literature. But it also is true that recent literary theory oftentimes tends towards the restatement of notions that are by now clich4s of medieval scholarship, even as it does so in a new-and distinctly uncomfortable-way. It might be said that the problem begins with the concept of the text itself. Peter Haidu remarks:
Selective Au-Etching on Aged GaAs-Based Devices (1999)

Abstract A specific problem in failure analysis of InGaAs/ AlGaAs laser diodes asked for a deprocessing tool able to selectively etch gold from a Ti/Pt/Au triple metal layer. Attempts made by the usual I2/KI etch confirmed the damage that it causes to the crystal stack, and non-uniform attack of gold. A new etch, indicated as Epta-Methyl-bis-diodine, has been successfully employed. Careful time control and detailed characterization of the complex metallization pattern of the devices allowed not only to properly expose the Pt layer, but also to preserve the overall electrical connection, thus maintaining the capability of both measuring the electrical characteristics at low current injection and collecting the EBIC signal from the etched device.
Proteomic analysis of epicardial and subcutaneous adipose tissue reveals differences in proteins involved in oxidative stress (2010)

Epicardial adipose tissue (EAT) is an endocrine organ adjacent to coronary arteries and myocardium without anatomy barriers. Locally produced adipokines may reflect or affect to cardiovascular physiology and pathology. Our aim was to study the protein expression profiles of EAT and subcutaneous adipose tissue (SAT) to identify local candidate molecules characterizing EAT in patients with cardiovascular disease. EAT and SAT samples were collected from 55 patients undergoing heart surgery. Proteins from these tissues were separated by two-dimensional (2D) gel electrophoresis, and differences between them were identified by MALDI-TOF/TOF spectra. Differences in protein levels were further investigated by real-time RT-PCR and Western blots, and production of reactive oxygen species (ROS) in EAT and SAT was evaluated by nitroblue tetrazolium chloride assays. ROS production was higher in EAT than SAT. We have found mRNA differences for catalase, glutathione S-transferase P, and protein disulfide isomerase, and 2D Western blots additionally showed post-translational differences for phosphoglycerate mutase 1; all four are related to oxidative stress pathways. EAT suffers greater oxidative stress than SAT in patients with cardiovascular diseases and exhibits associated proteomic differences that suggest the possibility of its association with myocardial stress in these patients.
Wideband Millimeter-Wave Elliptical Cavity-Backed Antenna for Circularly Polarized Radiation (2015)

A wideband millimeter-wave antenna backed by an elliptical cavity for circularly polarized radiation, excited by a dipole inclined to the major axis direction of the cavity, is reported in this letter. Experimental results show that the proposed antenna can achieve a bandwidth of 50-62.8 GHz for both axial ratio ≤ 3 dB and reflection coefficient | S <sub xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">11</sub> | ≤ - 10 dB, and an average broadside gain of 7.8 dBi. Studies on four critical parameters are performed for practical design. This design yields good directional radiation patterns and low fabrication cost.
Learning control with neural networks (2003)

A neural control model based on learning of the system inverse is proposed. Learning control is a control method wherein experience gained from previous performance is automatically used to improve future performance. A learning scheme called the inverse transfer learning scheme is introduced. Compared to previous learning schemes, this scheme provides faster convergences to the minimum error state and reflects properties of highly coupled nonlinear dynamic systems. The scheme is applied to the pole-balancing control problem through computer simulation to demonstrate control capability.< <ETX xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">></ETX>
Ondansetron Pretreatment to Alleviate Pain on Propofol Injection (1999)

We used a randomized, controlled, double-blinded design to study the effect of ondansetron (OND) pretreatment on the pain produced by the IV injection of propofol. Eighty patients were randomly assigned to one of two groups: Group I received 2 mL of IV 0.9% saline pretreatment, and Group II received OND (4 mg in 2 mg/mL solution) pretreatment in the dorsum of the hand, followed by propofol 1 min later. Pain was reduced significantly in the OND group (P < 0.05). Approximately one third of the patients in each group had myoclonic movements or skin rashes in the limb that received propofol. We conclude that the OND pretreatment may be used to reduce the incidence of pain on injection of propofol and to prevent postoperative nausea and vomiting. Implications: In a double-blinded, controlled study, IV ondansetron (4 mg) pretreatment was used to alleviate pain on injection of propofol. Ondansetron was successful in relieving pain without any adverse effect in a significant number of patients. (Anesth Analg 1999;89:197-9)

Modeling of L2 Cache Behavior for Thread-Parallel Scientific Programs on Chip Multi-Processors (2006)

It is critical to provide high performance for scientific programs running on a Chip Multi-Processor (CMP). A CMP architecture often has a shared L2 cache and lower storage hierarchy. The shared L2 cache can reduce the number of cache misses if the data are commonly shared by several threads, but it can also lead to performance degradation due to resource contention. Sometimes running threads on all cores can cause severe contention and increase the number of cache misses greatly. To investigate how a thread’s performance varies when it runs together with other threads on different cores, we develop an analytical model to predict the number of misses on the shared L2 cache, especially for thread-parallel numerical codes. We assume that the parallel threads work on homogeneous tasks and share a fully associative L2 cache. Stack processing technique and circular sequences are used to analyze the L2 trace to predict the number of compulsory misses, capacity misses on shared data, and capacity misses on private data, respectively. It is the first work to predict the number of L2 misses for threads that ∗ This material is based upon work supported by the National Science Foundation under grant No. 0444363.
Nano-Characterization of Ceramic-Metallic Interpenetrating Phase Composite Material using Electron Crystallography (2012)

Interpenetrating phase composites (IPCs) have unique mechanical and physical properties and thanks to these they could replace traditional single phase materials in numbers of applications.The most common IPCs are ceramic-metallic systems in which a ductile metal supports a hard ceramic making it an excellent composite material.Fireline, Inc., from Youngstown, OH manufactures such IPCs using an Al alloy-Al 2 O 3 based ceramic-metallic composite material.This product is fabricated using a Reactive Metal Penetration (RMP) process to form two interconnected networks.Fireline products are used, among others, as refractory materials for handling of high temperature molten metals.A novel route to adding a shape memory metal phase within a ceramic matrix has been proposed.A NiO preform was reacted with Ti to produce an IPC using a plasma arc melting system.This reaction is particularly interesting due to the possible formation of a Ni-Ti metal phase which could exhibit shape memory effects within the ceramic-metal network.Different ratios of NiO and TiO 2 (rutile) were reacted with Ti to investigate if the NiTi phase could be formed.In this thesis, two IPCs, one produced by the TCON RMP process and the other by using plasma arc-melting were investigated.The materials include Al-Fe alloy-Al 2 O 3 and NiO-Ti ceramic-metallic IPCs.Analysis was performed using scanning/transmission electron microscopy (S/TEM), energy dispersive spectroscopy (EDS), focused ion beam (FIB), and X-ray diffraction (XRD).Observations of these IPCs revealed all present phases within the composite material, obtained orientation relationships, and explored the growth mechanism of the RMP process which still puzzles the scientific community.This information is valuable for developing improved IPC systems with diverse elemental composition for a wide variety of applications.Inc. for providing me with the opportunity to study their company's products.Finally, I would like to thank my friends and family for listening to me talk hours upon hours about all the academics that I enjoy so much and for trying to understand what captivates me.
