CURRENT RESEARCH PROGRAMS AT THE USDA–ARS CITRUS AND SUBTROPICAL PRODUCTS LABORATORY (2006)

The USDA–ARS Citrus and Subtropical Products Laboratory is a food science and postharvest facility for fresh and processed fruits and vegetables of tropical and subtropical origin. The term “tropical” is extended to vegetables grown during the summer of temperate climates like tomato. There are also projects involving strawberry and blueberry since these are important crops for Florida. The majority of the work, however, is on citrus (70%). There are four projects at the facility including quality and by-product research. The two quality projects involve work on juice (mainly citrus juices) and fresh fruit flavor. The other quality project includes work on edible coatings or other surface treatments to reduce decay, water loss and to improve of the appearance of fresh or fresh-cut fruits and vegetables. The two by-product projects aim to develop products from citrus processing waste. One project mines citrus waste for edible fiber, nutraceuticals and compounds in grapefruit that enhance uptake of certain drugs. The other by-product project seeks to develop industrial products from the carbohydrates in citrus peel such as suspension aids and fuel ethanol.

This work deals with the electrical characterization down to 4K of fully depleted SOI MOSFET with a physical gate length down to 10nm. Temperature measurements are used to highlight source to drain tunneling: which is evidenced at room temperature for the first time. Finally resonant tunneling effect is observed.
A MEMS autonomous switched oscillator (2014)

This work presents the model, design and characterization of an autonomous electrostatic MEMS oscillator for sensing application. The proposed system, consisting of a parallel-plate electrostatic MEMS device, a DC voltage source and a displacement-dependent resistive circuit, is capable of sustaining oscillations autonomously. It can exhibit periodic or aperiodic behavior, impacted by its working point and by environmental parameters, e.g. pressure, temperature. Electronic and non-electronic information can be submitted or retrieved from the oscillator system that present a very rich behavior sensitive to external stimuli what makes it a good candidate for threshold sensing.
Histone Modifiers, YY1 and p300, Regulate the Expression of Cartilage-specific Gene, Chondromodulin-I, in Mesenchymal Stem Cells (2010)

Elucidating the regulatory mechanism for tissue-specific gene expression is key to understanding the differentiation process. The chondromodulin-I gene (ChM-I) is a cartilage-specific gene, the expression of which is regulated by the transcription factor, Sp3. The binding of Sp3 to the core-promoter region is regulated by the methylation status of the Sp3-binding motif as we reported previously. In this study, we have investigated the molecular mechanisms of the down-regulation of ChM-I expression in mesenchymal stem cells (MSCs) and normal mesenchymal tissues other than cartilage. The core-promoter region of cells in bone and peripheral nerve tissues was hypermethylated, whereas the methylation status in cells of other tissues including MSCs did not differ from that in cells of cartilage, suggesting the presence of inhibitory mechanisms other than DNA methylation. We found that a transcriptional repressor, YY1, negatively regulated the expression of ChM-I by recruiting histone deacetylase and thus inducing the deacetylation of associated histones. As for a positive regulator, we found that a transcriptional co-activator, p300, bound to the core-promoter region with Sp3, inducing the acetylation of histone. Inhibition of YY1 in combination with forced expression of p300 and Sp3 restored the expression of ChM-I in cells with a hypomethylated promoter region, but not in cells with hypermethylation. These results suggested that the expression of tissue-specific genes is regulated in two steps; reversible down-regulation by transcriptional repressor complex and tight down-regulation via DNA methylation.
Synthesis of the aromatase inhibitor 3-ethyl-3-(4-pyridyl)piperidine-2,6-dione and its enantiomers (1989)

Convenient syntheses of (R/S)-3-ethyl-3-(4-pyridyl)piperidine-2,6-dione (pyridoglutethimide) and its enantiomers are described; aromatase inhibitory activity was almost entirely confined to the 3R-enantiomer.
G-scan--mobile multiview 3-D measuring system for the analysis of the face. (2003)

The development of optical 3-D measuring techniques and their use in industrial quality assurance, in design, and for rapid prototyping has experienced strong growth. A large number of optical 3-D measuring methods and systems are on the market in dentistry. CAD/CAM production has become firmly established in dental medicine, not least due to the systematic introduction of the Cerec technique and the digiDent method. The scanners on which these technologies are based are designed for a relatively small measuring area. To be able to measure and three-dimensionally assess the face--and the numerous changes in the face/forehead/neck region--it was necessary to design and develop a self-calibrating measuring system with gray code for clinical use: the G-Scan measuring system. Objects up to a size of 500 x 500 x 400 mm can be acquired three-dimensionally with it, with a measuring inaccuracy of 10 to 70 microm in a typical measuring time of 15 s. The present article describes the measuring principle, the system parameters, and the features of the new measuring system, and illustrates the measuring results on 3-D displays of the face in static occlusion and in functional occlusion positions.
Thermoelectric properties of highly grain-aligned and densified Co-based oxide ceramics (2003)

Highly grain-aligned Ca3Co4O9 and (Ca2.7Sr0.2La0.1)(Co3.9Cu0.1)O9 ceramics were prepared by the magnetic alignment technique, and then treated by a spark plasma sintering process to increase their bulk densities. Thermoelectric properties were investigated from room temperature to 700 °C in air. Grain alignment is effective in lowering the electrical resistivity and has no obvious influence on the Seebeck coefficient, thus resulting in enhancement of the thermoelectric power factor. Substitution of Sr, La and Cu does not appreciably change the electrical resistivity and Seebeck coefficient, but significantly reduces the thermal conductivity.
Detection and localization of early lung cancer by fluorescence bronchoscopy (2000)

Preinvasive lesions, especially dysplastic lesions, are small. They are difficult to detect and localize by white-light bronchoscopy. Fluorescence bronchoscopy improves the detection rate. It is an important part of the armamentarium in the overall management of early lung cancer.
Remarkable Acceleration of Benzimidazole Synthesis and Cyanosilylation Reactions in a Supramolecular Solid Catalyst (2016)

Abstract A solid metal–organic catalyst with hydrophobic pockets and Lewis acid centers strongly accelerates the reaction rate for organic reactions. This is exemplified for the cyanosilylation of ketones and for the synthesis of benzimidazoles, for which very high selectivities are obtained. The solid can be recovered and reused and its behavior approaches that of a functional enzyme mimic.
Maturation of mouse NK cells is a 4-stage developmental program (2009)

Surface density of CD27 and CD11b subdivides mouse natural killer (NK) cells into 4 subsets: CD11b(low)CD27(low), CD11b(low)CD27(high), CD11b(high)CD27(high), and CD11b(high)CD27(low). To determine the developmental relationship between these 4 subsets, we used several complementary approaches. First, we took advantage of NDE transgenic mice that express enhanced green fluorescent protein (EGFP) and diphtheria toxin receptor specifically in NK cells. Diphtheria toxin injection leads to a transient depletion of NK cells, allowing the monitoring of the phenotype of developing EGFP+ NK cells after diphtheria toxin injection. Second, we evaluated the overall proximity between NK-cell subsets based on their global gene profile. Third, we compared the proliferative capacity of NK-cell subsets at steady state or during replenishment of the NK-cell pool. Fourth, we performed adoptive transfers of EGFP+ NK cell subsets from NDE mice into unirradiated mice and followed the fate of transferred cells. The results of these various experiments collectively support a 4-stage model of NK-cell maturation CD11b(low)CD27(low) --> CD11b(low)CD27(high) --> CD11b(high)CD27(high) --> CD11b(high)CD27(low). This developmental program appears to be associated with a progressive acquisition of NK-cell effector functions.
Laser-Induced Recrystallization of Perovskite Quantum Dots for Flexible/Wearable Light-Emitting Devices (2023)

Perovskite-structured quantum dots have received a lot of attentions to apply future light-emitting devices due to their superior optoelectronic properties. However, in normal annealing processes, perovskite quantum dots exhibited material unstability of the decreased lifetime, and the deteriorated optoelectrical properties. In this paper, we present a laser-assisted recrystallization method of perovskite quantum dots. Laser crystallized only the material through the instantaneous heating. The laser-heated material was optimized by using theoretical calculations and various material analyses.
A 1.2 V micropower CMOS active pixel image sensor for portable applications (2002)

Low-power image sensors are desirable for portable applications, including cellular phones, portable digital assistants (PDAs), and wireless security systems. Scaled CMOS technology has bright prospects for both high performance and low power image sensor systems. This image sensor for 1.2 V operation dissipates one-to-two orders of magnitude less power than the current state of the art CMOS active pixel sensors.
Direct imaging of polyethylene crystallites within block copolymer microdomains (2000)

Ruthenium tetroxide (RuO4) is a versatile agent for imparting mass density contrast to saturated hydrocarbon polymers. We have successfully employed RuO4 to examine the microdomain and crystallite morphologies of poly(ethylene-block-vinylcyclohexane) semicrystalline–glassy diblock copolymers via transmission electron microscopy (TEM). Ultrathin sections cut from blocks stained with RuO4 showed excellent contrast in TEM, revealing the individual polyethylene crystallites that formed within the preexisting block copolymer microdomains. The size and orientation of the crystallites, which previously could only be inferred from scattering data, are readily apparent in the micrographs. Moreover, such imaging directly reveals the lateral extent of the crystallites and the number of crystallites lying within the cross section of each microdomain. © 2000 John Wiley & Sons, Inc.

Experimental Investigation Into Bulk Performance of Three Different Style Inline Separators on Natural Gas at High Pressure, Different Liquid Loadings and Gas Flows (2022)

Abstract Inline vertical separators are commonly employed on natural gas transmission facilities (e.g., receipt stations) to primarily filter out liquid contaminants such as compressor oil, glycol, free water, etc. However, these contaminants have been found invariably in the piping system downstream of these separators, indicating the separators are not performing as required. The potential consequences of not removing such contaminants includes lower gas quality, impaired gas metering accuracy, corrosion and damage to equipment/instrumentation and adverse impact on industrial or residential end users. Historically, separators’ performance claims and guarantees in terms of efficiency of liquid removal are often of the order 98–99% of liquid droplet sizes ≥ 8μm. However, there is a lack of ability to verify these claims due to difficulties in quantifying liquid injection rates and droplet characteristics vs. liquid collected while in operation. Extensive testing was undertaken at TC Energy’s Gas Dynamic Test Facility in Didsbury, Canada on three different separators from different manufacturers, two are mesh vane type (MV-1 and MV-2), and the third is dual cyclonic type (DC). The tests were conducted in the range of 4–5 MPa and flow velocity in the range of 1.3–13 m/s in the DN150 inlet nozzle to the separator, i.e., at 10:1 turn down ratio. The injected liquid was industrial compressor oil, typically used in the gas transmission industry, and was injected at a loading in the range of 0. 06–1.8%. Four different spray nozzles were used to atomize the injected oil to a range of particle size distributions (PSD), characterized by median diameter size, D50, in the range of 50–90 μm. Test results revealed that the performance of these separators varied between 90–99.8% independent of liquid loading. The effective Souders-Brown K factor also varied between 0.15–0.27 m/s. Tests were also conducted following a batch of solid injection to determine the effects on liquid separation efficiency on MV-2 separator. It was found that the separation efficiency decreased by approximately 9% following a 7.075 kg batch of solid injection, likely due to the accumulation of solids in the vane-pack.
GuCI-induced unfolding of pig kidney dopa decarboxylase: Evidence for a multi-state process (1994)

The guanidinium chloride (GuCI) induced unfolding of dopa decarboxylase (DDC) has been studied by monitoring its effects on enzymatic activity. hydrodynamic volume. far-uv cd. and intrinsic fluorescence. Due to its spectral properties. pyridoxal 5′-phosphate (PLP) was also used as a probe of structural changes occuring at the active site during the unfolding/refolding process. The combination of these studies revealed that the unfolding of DDC occurs as a multi-step process minimally composed of at least three steps that could be identified at equilibrium. The first step occurs at 0–1 M GuCI and gives rise to an inactive dimeric species which is devoid of coenzyme. At 1–2.2 M GuCI a second transition is observed. consisting in subunit dissociation and partial loss of tertiary and secondary structure accompanied by structural alterations of the coenzyme microenvironment leading to a “structured monomer”. The third and final phase of the unfolding process is complete at about 4.5 M GuCl and is characterized by complete subunit unfolding. Further increasing the GuCI concentration failed to cause a change in any of the parameters followed. While enzymatic activity could never be regained starting from fully denatured protein. partial reactivation was seen starting from enzyme treated with GuCI concentrations less than 1.5 M. Together with an more in-depth investigation into the refolding, it is suggested that. at least under the experimental condition tested, the monomer-dimer transition is impaired during this process. These results are discussed in terms of a model for the unfolding/refolding of pig kidney dopa decarboxylase.
Photoluminescence of Titanosilsesquioxanes in Solution and Its Relevance for the Understanding of the Emission of Titanosilicates (2000)

A model for the titanium sites in solid titanosilicates is provided by titanosilsequioxanes in solution. Five model compounds, such as the one shown in the picture, have a variety of titanium coordination styles, were investigated. Emission maxima and lifetimes, quantum yields, and the effects of solvent and gas provide information on the nature of the titanium binding in the models and shown to be indicative of catalytically active titanium sites in the titanosilicates.
Performance analysis of magnetic recording systems (2002)

Approximations to the union bound performance of sequence detection in the presence of colored noise and an algorithm to compute bit error and error event probabilities are presented and compared to bit-by-bit simulation results. These computations, which are very accurate at bit error probabilities /spl les/10/sup -3/, are then used to analyze the performance of standard and reverse concatenated Reed-Solomon(RS)/modulation coding schemes for generalized partial-response channels corrupted by colored noise. The analysis is used to determine the optimum RS code rate for recording systems that are of current interest.
Worst case tolerance analysis and CLP-based multifrequency test generation for analog circuits (1999)

We present an algorithm for automatically generating minimal test sets for parametric faults in linear analog circuits. In a previous work we elaborated a multifrequency test generation method (TPG) for such circuit faults. The method was formulated as a series of optimization problems that were solved by sequential quadratic programming (SQP) available in MATLAB. Such a standard optimization method processes local information and, consequently, cannot guarantee that the found solution is global. This may lead to a poor test selection. Furthermore, the method is semiautomatic and depends on various parameters that must be selected by an experienced user. In this paper, we propose a method based on constraint logic programming (CLP) using relational interval arithmetic (RIA) to solve these optimization problems as a series of constraint satisfaction problems (CSPs). The method is fully automatic and provides tight and guaranteed bounds on the true range of a multivariable nonlinear function. The correctness of the bounds stems from the enumeration of subdivisions of the function and its variable domains while discarding those subdivisions containing no solution. The tightness (i.e., the closeness to the true range) of the bounds can be refined to any desired degree by increasing the fineness of subdivisions imposed on the variable domains and the stringency of the termination criterion at the cost of an increased CPU time. The TPG method was implemented in CLP (BNR) prolog. The effectiveness of our approach is illustrated on a number of nonlinear functions known to be difficult, and two realistic electronic circuits in the context of TPG. Our algorithm accelerated the computation of the various parameters related to the test of a biquadratic filter by a factor ranging from 11 to 29 as compared to the Monte Carlo method.
Semimetallic Atomic Layer Deposited TiS2 Thin Films for Contact Resistance Improvement of MoS2-based Thin Film Transistor (2023)

We introduced atomic layer deposition (ALD) of TiS <inf xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">2</inf> as contact layer for MoS <inf xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">2</inf> TFT to reduce the contact resistance.

Nondestructive Detection of Targeted Microbubbles Using Dual-Mode Data and Deep Learning for Real-Time Ultrasound Molecular Imaging (2020)

Ultrasound molecular imaging (UMI) is enabled by targeted microbubbles (MBs), which are highly reflective ultrasound contrast agents that bind to specific biomarkers. Distinguishing between adherent MBs and background signals can be challenging in vivo. The preferred preclinical technique is differential targeted enhancement (DTE), wherein a strong acoustic pulse is used to destroy MBs to verify their locations. However, DTE intrinsically cannot be used for real-time imaging and may cause undesirable bioeffects. In this work, we propose a simple 4-layer convolutional neural network to nondestructively detect adherent MB signatures. We investigated several types of input data to the network: "anatomy-mode" (fundamental frequency), "contrast-mode" (pulse-inversion harmonic frequency), or both, i.e., "dual-mode", using IQ channel signals, the channel sum, or the channel sum magnitude. Training and evaluation were performed on in vivo mouse tumor data and microvessel phantoms. The dual-mode channel signals yielded optimal performance, achieving a soft Dice coefficient of 0.45 and AUC of 0.91 in two test images. In a volumetric acquisition, the network best detected a breast cancer tumor, resulting in a generalized contrast-to-noise ratio (GCNR) of 0.93 and Kolmogorov-Smirnov statistic (KSS) of 0.86, outperforming both regular contrast mode imaging (GCNR = 0.76, KSS = 0.53) and DTE imaging (GCNR = 0.81, KSS = 0.62). Further development of the methodology is necessary to distinguish free from adherent MBs. These results demonstrate that neural networks can be trained to detect targeted MBs with DTE-like quality using nondestructive dual-mode data, and can be used to facilitate the safe and real-time translation of UMI to clinical applications.
