Pattern changes of pituitary peptides in rat after salt-loading as detected by means of direct, semiquantitative mass spectrometric profiling (1997)

We have established a differential peptide display method, based on a mass spectrometric technique, to detect peptides that show semiquantitative changes in the neurointermediate lobe (NIL) of individual rats subjected to salt-loading. We employed matrix-assisted laser desorption/ionization mass spectrometry, using a single-reference peptide in combination with careful scanning of the whole crystal rim of the matrix-analyte preparation, to detect in a semiquantitative manner the molecular ions present in the unfractionated NIL homogenate. Comparison of the mass spectra generated from NIL homogenates of salt-loaded and control rats revealed a selective and significant decrease in the intensities of several molecular ion species of the NIL homogenates from salt-loaded rats. These ion species, which have masses that correspond to the masses of oxytocin, vasopressin, neurophysins, and an unidentified putative peptide, were subsequently chemically characterized. We confirmed that the decreased molecular ion species are peptides derived exclusively from propressophysin and prooxyphysin (i.e., oxytocin, vasopressin, and various neurophysins). The putative peptide is carboxyl-terminal glycopeptide. The carbohydrate moiety of the latter peptide was determined by electrospray tandem MS as bisected biantennary Hex3HexNAc5Fuc. This posttranslational modification accounts for the mass difference between the predicted mass of the peptide based on cDNA studies and the measured mass of the mature peptide.
Multiphoton Interaction of Light with Dielectrics (2006)

When intense femtosecond optical pulses are focused inside fused silica localized material modification leads to self-organized periodic nanoplanes that are few nanometers wide and spaced at lambda/2 in the medium. We provide insight into their origin by invoking the concepts of strong-field physics and nano-plasmonics
Electrodeposited Nanophotonics (2014)

Prior work involving the detection and emission of light from semiconductor nanostructures has involved single crystalline nanomaterials. Here we review the use of electrodeposited, polycrystalline (pc), cadmium selenide (CdSe) in nanowires and nanogap device structures for photonics. The photodetectors and photon emitters we describe are symmetrical metal–semiconductor–metal (M-S-M) devices prepared either by the evaporation of two gold contacts onto linear arrays of pc-CdSe nanowires prepared using lithographically patterned nanowires electrodeposition (LPNE), or by the electrodeposition of pc-CdSe directly onto gold nanogaps. The properties of these devices for detecting light using photoconductivity, and for generating light by electroluminescence, are described.
Quantitative Microstructural Characterization of Precipitates and Oxide Inclusions in Inconel 625 Superalloy Additively Manufactured by L-PBF Method (2022)

Abstract In this study, we perform quantitative characterization of precipitates and oxide inclusions in Inconel 625 additively manufactured by the laser powder-bed fusion (L-PBF) process. The application of different microscopy techniques allowed us to characterize the microstructure at micro- and nano-scale in the as-built and stress-relieved condition and correlate the features of grains and cellular substructure with parameters of particles along the planes parallel and perpendicular to the build direction. The optimized imaging conditions and image analysis procedure allowed easily distinguishing precipitates and oxide inclusions and performing their quantitative analysis. The results showed that intercellular areas are the preferential sites of precipitation of the Laves phase and NbC carbides with diameters in the range of 10 to 440 nm. Moreover, aluminum oxide inclusions with diameters in the range of 30 to 300 nm are randomly distributed. Regardless of the processing conditions of the examined samples, the influence of the stress-relief annealing on the secondary phases was not observed. In both the as-built and stress-relieved samples, the size of precipitates is in submicrometer scale. The analysis provided detailed information about the parameters of particles depending on the orientation versus the build direction. It was demonstrated that despite the tendency for columnar grain morphology and the anisotropy of the cellular substructure, the particle distribution is almost uniform throughout the volume of the additively manufactured L-PBF Inconel 625.

Low-Voltage Organic Field Effect Transistors with a 2-Tridecyl[1]benzothieno[3,2-b][1]benzothiophene Semiconductor Layer (2012)

An asymmetric n-alkyl substitution pattern was realized in 2-tridecyl[1]benzothieno[3,2-b][1]benzothiophene (C(13)-BTBT) in order to improve the charge transport properties in organic thin-film transistors. We obtained large hole mobilities up to 17.2 cm(2)/(V·s) in low-voltage operating devices. The large mobility is related to densely packed layers of the BTBT π-systems at the channel interface dedicated to the substitution motif and confirmed by X-ray reflectivity measurements. The devices exhibit promising stability in continuous operation for several hours in ambient air.
Litomosoides carinii: retardation of worm growth and of migration of challenge infections in jirds (Meriones unguiculatus) (1985)

Inbred jirds (Meriones unguiculatus) were divided into three groups; each animal in two of the groups was infected with 30 infective larvae (L3) of Litomosoides carinii. When these infections were patent, the jirds of one of the two infected groups plus those of the third group were injected with 30 L3 L. carinii each. All animals were killed either on day 14 or 24 after the second infection for the recovery, enumeration and measurement of all worms and developing larvae. Challenge larvae were stunted (smaller) and fewer than control larvae. Additionally, fewer challenge larva were recovered on day 14 than on day 24, indicating that migration to the pleural cavity was retarded.
Dense 3D fractal tree structures as miniature end-loaded dipole antennas (2003)

As part of an effort to further improve modern communication system technology, researchers are studying different approaches for creating new and innovative antennas. One technique that has received a lot of recent attention involves combining aspects of fractal geometry with antenna design. This rapidly growing area of research is known as fractal antenna engineering. One particular class of antenna configurations is based on fractal trees. Fractal tree structures can be exploited in antenna designs to produce multiband characteristics or to achieve miniaturization. Dipole antennas that use fractal tree structures as end loads can achieve a resonant frequency lower than a standard dipole of comparable length. We discuss ways to improve antenna miniaturization techniques that employ fractal tree geometries as end loads by increasing the density of branches (i.e., by using trees with a higher fractal dimension).

Cluster Sampling and Its Applications in Image Analysis (2004)

Markov chain Monte Carlo (MCMC) methods have been used in many fields (physics, chemistry, biology, and computer science) for simulation, inference, and optimization. The essence of these methods is to simulate a Markov chain whose state X follows a target probability X ∼ π(X). In many applications, π(X) is defined on a graph G whose vertices represent elements in the system and whose edges represent the connectivity of the elements. X is a vector of variables on the vertices which often take discrete values called labels or colors. Designing rapid mixing Markov chain is a challenging task when the variables in the graph are strongly coupled. Methods, like the single-site Gibbs sampler, often experience long waiting time. A well-celebrated algorithm for sampling on graphs is the Swendsen-Wang (1987) (SW) method. The SWmethod finds a cluster of vertices as a connected component after turning off some edges probabilistically, and flips the color of the cluster as a whole. It is shown to mix rapidly under certain conditions. Unfortunately, the SW method is only applicable to the Ising/Potts models and slow down critically in the presence of "external fields" i.e. likelihood in Bayesian inference.In this paper, we present a general cluster sampling method which achieves the following objectives. Firstly, it extends the SW algorithm to general Bayesian inference on graphs. Especially we focus a number of image analysis problems where the graph sizes are in the order of O(103) — O(106) with O(1) connectivity. Secondly, the edge probability for clustering the vertices are discriminative probabilities computed from data. Empirically such data driven clustering leads to much improved efficiency. Thirdly, we present a generalized Gibbs sampler which samples the color of a cluster according to a conditional probability (like the Gibbs sampler) weighted by a product of edge probabilities. Fourthly, we design the algorithm to work on multi-grid and multi-level graphs. The algorithm is tested on typical problems in image analysis, such as image segmentation and motion analysis, In our experiments, the algorithm is O(102) orders faster than the single-site Gibbs sampler. In the literature, there are several ways for interpreting the SW-method which leads to various analyses or generalizations, including random cluster model (RCM), data augmentation, slice sampling, and partial decoupling. We take a different route by interpreting SW as a Metropolis-Hastings step with auxiliary variables for proposing the moves or we can view it as a generalized hit-and-run method.

[In vivo evaluation of expressed protein function by PET]. (2005)

Positron Emission Tomography (PET) allows in vivo visualization of the expression and function of protein using a radioligand. Quantitative analysis of serotonin transporter, receptors, and the function of P-Glycoprotein has been performed in living human brains. Furthermore, the relationship between the phenotype of those proteins and their genetic polymorphism has also been investigated. Regarding the effect of antipsychotics on dopamine D2 receptor, occupancy and its time-course have been measured in a living body using PET. This approach can provide in vivo pharmacological evidences of antipsychotics and establish a rational therapeutic strategy. PET is a powerful tool not only in the field of brain research but also drug discovery and individual medicine.
Airflow resistance of wheat bedding as influenced by the filling method (2008)

A study was conducted to estimate the degree of variability of the airflow resistance in wheat caused by the filling method, compaction of the sample, and airflow direction. Two types of grain chambers were used: a cylindrical column 0.95 m high and 0.196 m in diameter, and a cubical box of 0.35 m side. All factors examined were found to influence considerably the airflow resistance. Gravitational axial filling of the grain column from three heights (0.0, 0.95 and 1.8 m) resulted in the pressure drops of 1.0, 1.3, and 1.5 kPa at the airflow velocity of 0.3 m/s. Consolidation of axially filled samples by vibration resulted in a maximum 2.2 times increase in airflow resistance. The tests with cubical sample showed that in axially filled samples the pressure drop in vertical direction was maximum 1.5 times higher than in horizontal directions. In the case of asymmetrically filled samples, the pressure drop at the airflow velocity of 0.3 m/s in vertical direction Z was found to be 1.3 of that in horizontal direction X and 1.95 times higher than with horizontal direction Y, perpendicular to X. Variations in airflow resistance in values comparable to that found in the present project may be expected in practice.
Energy efficient object detection on the mobile GP-GPU (2017)

Smartphones and tablets now include General Purpose Graphics Processing Units (GP-GPUs) that can be used for computation beyond driving the high-resolution screens. In this paper we present a mobile GP-GPU-based object detection algorithm and system, based on the work by Viola and Jones (which is also used in the OpenCV library). This implementation achieved twofold speed up compared to OpenCV running on the CPU of the same smartphone, and up to 84% energy saving. Interestingly, the new implementation saves energy vs. the CPU even when it executes slower than the OpenCV implementation, because the GPU consumes less power than the CPU, something that is not typical in desktop or laptop systems.

An End-to-End Measurement-Based Scheduling Architecture for ATM Networks (1999)

ATM networks provide end-to-end QoS guarantees to connections for theirlifetime in the form of bounds on delay, error and/or loss. Theguarantees are important for real-time connections in which losses areirrecoverable and delays cause interruptions in service. Performancemanagement involves measurement of QoS parameters and applying controlmeasures, if required, to improve performance or resource utilization. Inthis paper, we propose a new hierarchical scheduling algorithm based ondynamic priorities which are adaptive to end-to-end QoS measurements madeon QoS sensitive (real-time) connections. This architecture can providebounds on average delay and delay variation with varying backgroundnetwork traffic. <P><P><I>This paper has been submitted to INFOCOM 2000, Tel Aviv Israel, March 26-30, 2000.</I>
Thin-channel electrospray emitter (2023)

An electrospray device includes a high voltage electrode chamber. The high voltage electrode chamber includes an inlet for receiving a fluid to be ionized and for directing the fluid into the chamber and at least one electrode having an exposed surface within the chamber. A flow channel directs fluid over a surface of the electrode and out of the chamber. The length of the flow channel over the electrode is greater than the height of the flow channel over the electrode, thereby producing enhanced mass transport to the working electrode resulting in improved electrolysis efficiency. An outlet is provided for transmitting the fluid out from the electrode chamber. A method of creating charged droplets includes flowing a fluid over an electrode where the length over the electrode is greater than the height of the fluid flowing over the electrode.

Surfaces of Strongly Confined Polymer Thin Films Studied by X-Ray Scattering (1999)

The surfaces of thermally annealed thin polystyrene films on silicon were investigated by specular and diffuse x-ray scattering. The data cannot be interpreted satisfactorily with capillary wave calculations assuming attractive van der Waals substrate film interactions. The analysis shows that polystyrene films coated on silicon substrates are in a strongly confined state even for film thicknesses much larger than the radius of gyration, possibly due to strong confinement that arises from the interaction at the polymer/substrate interface and the viscoelastic behavior of the thin films.

Characteristic Design of Microwave Dielectric Materials by Using Self-Flux Compositions (2006)

In order to improve the sinterability and controllability of dielectric properties, we focused on self-flux composition. In the case of Ba(Mg1/3Nb2/3)O3, we selected Ba(1-b)NbbOd as self-flux system and investigated correlations between Q-factor and the b value. Interestingly, high Q-value was obtained only at the b=0.45. Moreover, the dielectric constant and tf change linearly by the quantity of Ba0.55Nb0.45Od under keeping up high-Q value. As a result, it was indicated that the dielectric properties could be controlled by the assumption of stoichiometric composition and liquid phase consisted by self-flux.
Low Cost, Epitaxial Growth of II-VI Materials for Multijunction Photovoltaic Cells (2014)

Multijunction solar cells have theoretical power conversion efficiencies in excess of 29% under one sun illumination and could become a highly disruptive technology if fabricated using low cost processing techniques to epitaxially grow defect tolerant, thin films on silicon. The PLANT PV/Molecular Foundry team studied the feasibility of using cadmium selenide (CdSe) as the wide band-gap, top cell and Si as the bottom cell in monolithically integrated tandem architecture. The greatest challenge in developing tandem solar cells is depositing wide band gap semiconductors that are both highly doped and have minority carrier lifetimes greater than 1 ns. The proposed research was to determine whether it is possible to rapidly grow CdSe films with sufficient minority carrier lifetimes and doping levels required to produce an open-circuit voltage (Voc) greater than 1.1V using close-space sublimation (CSS).

A fast-speed heater with internal and external heating for lithium-ion batteries at low temperatures (2018)

This paper proposes an automotive on-board heater for lithium-ion batteries at low temperatures without the requirement of external power supplies. The proposed heater only needs one MOSFET for one cell, resulting in a smaller size and lower cost, which can be easily applied to electric vehicles (EVs). One high-frequency PWM signal is employed to drive all MOSFETs, and batteries can be heated internally by the ohmic losses and warmed externally by the switching losses and conduction losses of MOSFETs, leading to a high heating speed and efficiency. In addition, the proposed system with a higher switching frequency and smaller duty cycle can also realize the passive balancing for battery cells. Experimental results show that the proposed heater, by generating a periodic ramped discharged current with the amplitude of 3.7 C and the switching frequency of 150 kHz, can heat Lithium-Ion batteries from -20 °C to 0 °C within 1.9 min, consuming about 5 % of cell energy.
