Liquefying Lignins: Determining Phase-Transition Temperatures in the Presence of Aqueous Organic Solvents (2021)

Under appropriate conditions of temperature and solvent composition, single-phase aqueous organic solvents are capable of liquefying lignin to form a lignin-rich liquid phase separate from the solvent phase, creating liquid–liquid equilibrium. The extent to which this phenomenon occurs when Kraft lignin is combined with the solvents methanol, ethanol, isopropanol, and acetone was determined, with solid–liquid (SL) to liquid–liquid (LL) phase-transition temperatures being measured over the range of applicable organic–water compositions. Lignins tested from a variety of biomass sources were all discovered to form this liquid–liquid equilibrium with aqueous ethanol solutions. Furthermore, the formation of such phase behavior between lignin and economical, green solvents creates new opportunities for the large-scale purification and fractionation of raw bulk (i.e., technical) lignins.
Superconductivity in Polycrystalline Diamond Thin Films (2005)

Superconductivity was discovered in heavily boron-doped diamond thin films deposited by the microwave plasma assisted chemical vapor deposition (MPCVD) method. Advantages of the MPCVD deposited diamond are the controllability of boron concentration in a wide range, and a high boron concentration, especially in (111) oriented films, compared to that of the high-pressure high-temperature method. The superconducting transition temperatures are determined to be 8.7K for Tc onset and 5.0K for zero resistance by transport measurements. And the upper critical field is estimated to be around 7T.
Preparative Separation of Mixtures by Mass Spectrometry (2005)

A specially designed mass spectrometer which allows for preparative separation of mixtures is described. This mass spectrometer allows for large ion currents, on the order of nanoamperes, to be produced by electrospray and transmitted into a high vacuum. Accumulation of nanomole quantities of collected and recovered material in several hours is demonstrated. The use of high-velocity ions reduces space charge effects at high ion currents. Separation of mass occurs simultaneously for all ions, providing a 100% duty cycle. The use of a linear dispersion magnet avoids compression at higher m/z ratios. A deceleration lens slows the ions to allow for soft landing at low kinetic energy. The ions are neutralized by ion pairing on an oxidized metal surface. Retractable landing plates allow for easy removal of the separated components.
Trellises and new trellis-based decoding algorithms for codes (2002)

This paper presents the fundamental concepts, basic structures, and construction of trellises for linear codes. It also includes a number of trellis-based decoding algorithms. Particularly, two new decoding algorithms, one for block codes and the other for convolutional codes, are presented. Both algorithms are more efficient than the well known Viterbi (1967) algorithm.
Confirmation of the Genome Position and Mass of the Viral Protein, Vp3, of<i>Solenopsis invicta</i>Virus 1 (Picornavirales: Dicistroviridae) Infecting the Red Imported Fire Ant (Hymenoptera: Formicidae) (2012)

Solenopsis invicta virus 1 (SINV-1) is the first virus to be discovered and characterized in any ant species (Valles et al. 2004). The virus exhibits a host range limited to fire ants in the Solenopsis genus (Valles et al. 2007). The single-stranded RNA genome is composed of 8,026 nucleotides containing 2 large open reading frames (ORFs) in the sense orientation with an untranslated region (UTR) at each end and between the two ORFs. The 5’-proximal ORF encodes for the non-structural proteins, helicase, protease, and RNA-dependent RNA polymerase (RdRp) and the 3’-proximal ORF for the structural (or capsid) proteins. ORF 2 was originally reported to commence at nucleotide position 4,390 at a canonical AUG start codon. However, it was later revealed empirically to actually start at codon GCU (genome position 4423-4425) which encodes for an alanine (Valles and Hashimoto 2008). SDS-PAGE analysis of purified SINV-1 particles yields 3 major (VP1, VP2, VP3) and one minor (VP4) capsid proteins. N-terminal analysis has revealed the margins of the capsid proteins and the corresponding scissile bonds within the structural polyprotein (Valles and Hashimoto 2008). Amino acid residues at these junctions were consistent with other dicistroviruses and unclassified picorna-like insect-infecting viruses (Liljas et al. 2002). The objective of this short communication was to confirm production and genome location of VP3 within the SINV-1 structural polyprotein using Western analysis. Polyclonal antibodies were synthesized from a recombinant peptide sequence obtained from the predicted amino acid sequence of VP3 (i.e., SRGGYRYKFFADDN). The peptide sequence is located at amino acid positions 9971010 of the structural polyprotein (Fig. 1A). Polyclonal antibodies were raised in a rabbit host by GenScript USA, Inc. (Piscataway, NJ) according to the company’s standard protocols. Ants used for purification of virus were collected by excavating nests from locations in Gainesville, FL. Colonies were examined by RT-PCR methods to identify ants exclusively infected with
Evidence for Quantized Displacement in Macroscopic Nanomechanical Oscillators (2005)

We report the observation of discrete displacement of nanomechanical oscillators with gigahertz-range resonance frequencies at millikelvin temperatures. The oscillators are nanomachined single-crystal structures of silicon, designed to provide two distinct sets of coupled elements with very low and very high frequencies. With this novel design, femtometer-level displacement of the frequency-determining element is amplified into collective motion of the entire micron-sized structure. The observed discrete response possibly results from energy quantization at the onset of the quantum regime in these macroscopic nanomechanical oscillators.
Glucose sensing by means of silicon photonics (2014)

Diabetes is a fast growing metabolic disease, where the patients suffer from disordered glucose blood levels. Monitoring the blood glucose values in combination with extra insulin injection is currently the only therapy to keep the glucose concentration in diabetic patients under control, minimizing the long-term effects of elevated glucose concentrations and improving quality of life of the diabetic patients. Implantable sensors allow continuous glucose monitoring, offering the most reliable data to control the glucose levels. Infrared absorption spectrometers offer a non-chemical measurement method to determine the small glucose concentrations in blood serum. In this work, a spectrometer platform based on silicon photonics is presented, allowing the realization of very small glucose sensors suitable for building implantable sensors. A proof-of-concept of a spectrometer with integrated evanescent sample interface is presented, and the route towards a fully implantable spectrometer is discussed.
Optimal statistical chip disposition (2011)

A chip disposition criterion is used to decide whether to accept or discard a chip during chip testing. Its quality directly impacts both yield and product quality loss (PQL). The importance becomes even more significant with the increasingly large process variation. For the first time, this paper rigorously formulates the optimal chip disposition problem, and proposes an elegant solution. We show that the optimal chip disposition criterion is different from the existing industry practice. Our solution can find the optimal disposition criterion efficiently with better yield under the same PQL constraint, or lower PQL under the same yield constraint.
Design and Synthesis of Piperazine Sulfonamide Cores Leading to Highly Potent HIV-1 Protease Inhibitors (2017)

Using the HIV-1 protease binding mode of <b>MK-8718</b> and <b>PL-100</b> as inspiration, a novel aspartate binding bicyclic piperazine sulfonamide core was designed and synthesized. The resulting HIV-1 protease inhibitor containing this core showed an 60-fold increase in enzyme binding affinity and a 10-fold increase in antiviral activity relative to <b>MK-8718</b>.
Automatic thoracic anatomy segmentation on CT images using hierarchical fuzzy models and registration (2016)

The hierarchical structure and location relation integrated into the model provide the initial pose for registration and make the recognition process efficient and robust. The 3D fuzzy model combined with hierarchical affine registration ensures that accurate recognition can be obtained for both nonsparse and sparse organs. Tailoring the registration process for each organ by specialized similarity criteria and updating the organ intensity properties based on refined recognition improve the overall segmentation process.
A New Model of Progressive Visceral Leishmaniasis in Hamsters by Natural Transmission via Bites of Vector Sand Flies (2013)

Canonical and Longitudinal Dual-Mode Dielectric Resonator Filters Without Iris (1987)

Two bandpass filter realizations using dual-mode dielectric resonators in simple tubular enclosures are described. The new configurations do not require iris to achieve the couplings among the resonators. This eliminates the need for the most expensive machined parts of the filters, which require tight tolerances. The realizations also achieve lower midband insertion losses than comparable filters with iris, because conduction currents on the metallic cavity ends are eliminated. Measured results on two four-pole elliptic function experimental filters realized in the new structures agreed closely with theory.
Light-scattering-based high contrast optical touch sensor architectures in transmissive and reflective configurations (2005)

Transmissive and reflective optical touch switch architectures based on the use of light scattering are proposed. Key features include high ON/OFF switching ratio, tunable sensitivity, ease of implementation, and no leakage optical beam incident on the user. Experimental proof of concept using a visible laser diode and a plastic Dove prism arranged in the transmissive configuration shows a high 24.4 dB contrast ratio which is a hundred times higher than obtained in the previous total internal reflection-based optical touch switch. In addition, switching response in milliseconds is also investigated for both lifting and sliding the fingertip out of the touching surface of the optical touch switch. Our light scattering-based optical touch switch also supports multiple keystroke operation.
MicroRNAs in Cardiac Development (2010)

The transcriptional regulation of cardiovascular development requires precise spatiotemporal control of gene expression, and heterozygous mutations of transcription factors have frequently been implicated in human cardiovascular malformations. A novel mechanism involving post-transcriptional regulation by small, noncoding microRNAs (miRNAs) has emerged as a central regulator of many cardiogenic processes. We are beginning to understand the functions that miRNAs play during essential biologic processes, such as cell proliferation, differentiation, apoptosis, stress response, and tumorigenesis. The identification of miRNAs expressed in specific cardiac and vascular cell types has led to the discovery of important regulatory roles for these small RNAs during cardiomyocyte differentiation, cell cycle, conduction, and vessel formation. Here, we overview the recent findings on miRNA regulation in cardiovascular development. Further analysis of miRNA function during cardiovascular development will allow us to determine the potential for novel miRNA-based therapeutic strategies.
Do What I Mean, Not What I Say! Design Considerations for Supporting Intent and Context in Analytical Conversation (2019)

Natural language can be a useful modality for creating and interacting with visualizations but users often have unrealistic expectations about the intelligence of natural language systems. The gulf between user expectations and system capabilities may lead to a disappointing user experience. So - if we want to engineer a natural language system, what are the requirements around system intelligence? This work takes a retrospective look at how we answered this question in the design of Ask Data, a natural language interaction feature for Tableau. We examine two factors contributing to perceived system intelligence: the system's ability to understand the analytic intent behind an input utterance and the ability to interpret an utterance contextually (i.e. taking into account the current visualization state and recent actions). Our aim was to understand the ways in which a system would need to support these two aspects of intelligence to enable a positive user experience. We first describe a pre-design Wizard of Oz study that offered insight into this question and narrowed the space of designs under consideration. We then reflect on the impact of this study on system development, examining how design implications from the study played out in practice. Our work contributes insights for the design of natural language interaction in visual analytics as well as a reflection on the value of pre-design empirical studies in the development of visual analytic systems.

Erbium-Doped Fiber Amplifiers For High-Speed Fiber-Optic Communication Systems (1990)

The bandwidth, gain, saturation power and noise of the erbium-doped fiber-amplifier (EDFA) are reviewed in the context of high-speed optical communication systems. Recent experiments which have used EDFA postamplifiers, repeaters and preamplifiers to enhance the performance of fiber-optic systems are discussed.
Enterovirus 71 Infection of Monocytes with Antibody-Dependent Enhancement (2010)

Enterovirus (EV) is an RNA virus that has circulated with different serotypes and genotypes worldwide. Enterovirus 71 (EV71) is a major neurotropic virus that causes severe brain stem encephalitis (BE) in infants and young children. The most vulnerable age for fatal infection is 6 to 11 months. This is associated with the coincident decline in maternal antibodies. The current report describes our finding that EV71 can infect human peripheral blood monocytes. We were able to show that EV71 infection is enhanced in the monocytic cell line THP-1 by the presence of subneutralizing concentrations of anti-EV71 antibodies. We also found that antibody-dependent enhancement (ADE) is mediated in part by Fcγ receptors. These observations support the concept that ADE augments the infectivity of EV71 for human monocytes and contributes to the age-dependent pathogenesis of EV71-induced disease. The ADE phenomenon must be considered during the development of an EV71 vaccine.
In situ heating to improve adhesion for parylene-on-parylene deposition (2012)

A new technique of using “in-situ heating” to enhance adhesion for parylene-on-parylene deposition is reported in this paper. This method is compared with existing physical or chemical adhesion-enhancing methods and the results show clear advantages of this new technique. The physics is believed to be that the mobility of deposition-involved molecules (including the substrate parylene polymer chains and adsorbed monomers during deposition) is enhanced when deposition temperature rises, especially above the glass transition temperature of the substrate parylene. Each sample is patterned and then soaked in 0.9% saline at 90°C, and the undercut between two parylene layers due to the attack from saline during the soaking test could be observed. The undercut rate is measured to quantify the adhesion strength.
Water Extract of Ashwagandha Leaves Has Anticancer Activity: Identification of an Active Component and Its Mechanism of Action (2013)

Correcting image blur in spiral, retraced in/out (RIO) acquisitions using a maximized energy objective (2018)

The maximized energy objective function can accurately deblur RIO acquisitions over a wide spectrum of off resonance frequencies.
Spatial Spectrum Holes for Cognitive Radio with Directional Transmission (2008)

In this paper, we propose a cognitive radio (CR) transmission scheme, which enables secondary users to coexist with primary users by exploiting spatial spectrum holes (SSHs) through directional antennas or antenna arrays with beamforming. To ensure reliable CR links and avoid interference to primary users, some CR users may act as relays . We investigate successful communication probability of CR users when this scheme is applied. We further demonstrate that the spectrum efficiency can be greatly improved by multiplexing CR links with directional transmission.
HIFα Targeted for VHL-Mediated Destruction by Proline Hydroxylation: Implications for O <sub>2</sub> Sensing (2001)

HIF (hypoxia-inducible factor) is a transcription factor that plays a pivotal role in cellular adaptation to changes in oxygen availability. In the presence of oxygen, HIF is targeted for destruction by an E3 ubiquitin ligase containing the von Hippel-Lindau tumor suppressor protein (pVHL). We found that human pVHL binds to a short HIF-derived peptide when a conserved proline residue at the core of this peptide is hydroxylated. Because proline hydroxylation requires molecular oxygen and Fe(2+), this protein modification may play a key role in mammalian oxygen sensing.
Enterprise workflow resource management (1999)

Resource management is a key issue in providing resource independence and efficient use of workflow resources. This paper outlines a design of such a resource management system for enterprise workflow environments. It is capable of handling a large number of workflow resources that are independently managed by pre-existing resource systems. It integrates these external resource systems at the schema level without duplicating individual resource information. Resource specification is greatly simplified by providing process designers with integrated views of enterprise workflow resources at different levels based on a unified resource model. Dynamic behaviors of workflow resources are supported through powerful resource policies.
<i>In vitro</i> culture of <i>Pandanus amaryllifolius</i> and enhancement of 2‐acetyl‐1‐pyrroline, the major flavouring compound of aromatic rice, by precursor feeding of <scp>L</scp>‐proline (2005)

Abstract Shoots, plantlets and semi‐differentiated callus (SDC) cultures of Pandanus amaryllifolius capable of producing high levels of basmati rice flavour were established in vitro using Murashige and Skoog nutrient medium. A total of 10% of the initial explants responded to produce shoot cultures in the presence of benzylamino purine (BAP) (0.5 mg L −1 ) and glutamine (100 mg L −1 ). Leaf explants and basal portions of shoots produced SDC whereas elongated in vitro shoots could be continuously multiplied, using BAP (1.5 mg L −1 ) and kinetin (Kn) (1.0 mg L −1 ), and rooted in half‐strength medium for ex vitro cultivation leading to a process of micropropagation. Steam‐distillation extraction (SDE) followed by gas chromatography‐mass spectrometry (GC‐MS) analysis of various cultured organs and spent liquid medium used for SDC revealed the presence of 2‐acetyl‐1‐pyrroline (2‐AP) to various extents. This 2‐AP compound has been identified as the major flavouring compound of scented basmati and other scented rice varieties. 2‐AP was found to be highest, on a fresh weight basis, in SDC (19.7 mg kg −1 ) on the 40th day, whereas in vitro roots, shoots and field leaves (of one‐year‐old plant) had lower levels of 15, 6.8 and 14 mg kg −1 , respectively. Further enhancement of 2‐AP in SDC using precursor was possible by feeding into medium 1 mmol L −1 of L ‐proline where a highest level of 21.67 ppm of 2‐AP accumulated on the seventh day whereas a higher level of 2 mmol L −1 of L ‐proline suppressed 2‐AP levels. The present report is the first on the tissue culture studies of P. amaryllifolius where continuous production of plantlets as well as synthesis of high levels of 2‐AP has been documented.

Acoustically Induced Structural Fatigue of Piping Systems (1999)

Piping systems handling high-pressure and high-velocity steam and various process and hydrocarbon gases through a pressure-reducing device can produce severe acoustic vibration and metal fatigue in the system. It has been previously shown that the acoustic fatigue of the piping system is governed by the relationship between fluid pressure drop and downstream Mach number, and the dimensionless pipe diameter/wall thickness geometry parameter. In this paper, the devised relationship is extended to cover acoustic fatigue considerations of medium and smaller-diameter piping systems.
