Two cellulases, CelA and CelC, from the polycentric anaerobic fungus Orpinomyces strain PC-2 contain N-terminal docking domains for a cellulase-hemicellulase complex (1997)

Two cDNAs encoding two cellulases, CelA and CelC, were isolated from a cDNA library of the polycentric anaerobic fungus Orpinomyces sp. strain PC-2 constructed in Escherichia coli. Nucleotide sequencing revealed that the celA cDNA (1,558 bp) and celC cDNA (1,628 bp) had open reading frames encoding polypeptides of 459 (CelA) and 449 (CelC) amino acids, respectively. The two cDNAs were 76.9 and 67.7% identical at the nucleotide and amino acid levels, respectively. Analysis of the deduced amino acid sequences showed that starting from the N termini, both CelA and CelC had signal peptides, which were followed by noncatalytic repeated peptide domains (NCRPD) containing two repeated sequences of 33 to 40 amino acid residues functioning as docking domains. The NCRPDs and the catalytic domains were separated by linker sequences. The NCRPDs were homologous to those found in several hydrolases of anaerobic fungi, whereas the catalytic domains were homologous to the catalytic domains of fungal cellobiohydrolases and bacterial endoglucanases. The linker sequence of CelA contained predominantly glutamine and proline residues, while that of CelC contained mainly threonine residues. CelA and CelC did not have a typical cellulose binding domain (CBD). CelA and CelC expressed in E. coli rapidly decreased the viscosity of carboxymethyl cellulose (CMC), indicating that there was endoglucanase activity. In addition, they produced cellobiose from CMC, acid-swollen cellulose, and cellotetraose, suggesting that they had cellobiohydrolase activity. The optimal activity conditions with CMC as the substrate were pH 4.3 to 6.8 and 50 degrees C for CelA and pH 4.6 to 7.0 and 40 degrees C for CelC. Despite the lack of a CBD, CelC displayed a high affinity for microcrystalline cellulose, whereas CelA did not.
A comparative study of the thermal interface materials with graphene and boron nitride fillers (2014)

We report the results of an experimental study that compares the performance of graphene and boron nitride flakes as fillers in the thermal interface materials. The thickness of both fillers varied from a single atomic plane to about a hundred. The measurements have been conducted using a standard TIM tester. Our results show that the addition of a small fraction of graphene (f=4 wt%) to a commercial thermal interface material increases the resulting apparent thermal conductivity substantially stronger than the addition of boron nitride. The obtained data suggest that graphene and fewlayer graphene flakes couple better to the matrix materials than the boron nitride fillers. A combination of both fillers can be used to increase the thermal conductivity while controlling the electrical conduction.
Practical measurement and modeling of spectral skin reflectance (2019)

Accurate modeling and rendering of human skin appearance has been a long standing goal in computer graphics. Of particular importance has been the realistic modeling and rendering of layered subsurface scattering in skin for which various bio-physical models have been proposed based on the spectral distribution of chromophores in the epidermal and dermal layers of skin [Donner and Jensen 2006; Donner et al. 2008; Jimenez et al. 2010]. However, measurement of the spectral parameters of absorption and scattering of light for such bio-phyisical models has been a challenge in computer graphics. Previous works have either borrowed parameters for skin-type from tissue-optics literature [Donner and Jensen 2006], or employed extensive multispectral imaging for inverse rendering detailed spatially varying parameters for a patch of skin [Donner et al. 2008]. Closest to our approach, Jimenez et al. [2010] employed observations under uniform broadband illumination to estimate two dominant parameters (melanin and hemoglobin concentrations) for driving a qualitative appearance model for facial animation.

Hybrid decision feedback equalization (2004)

By modeling the effects of slicer errors, we derive an algorithm for determining hybrid DFE coefficients which account for the increase in interference from error propagation. The coefficients of the hybrid DFE can be determined adaptively through the LMS algorithm by including an SINR dependent "leakage" factor in the feedback filter update equation. The hybrid DFE coefficients reduce to those of a linear equalizer (LE) at low SNR and a DFE at high SNR, while achieving an optimal compromise between these extremes. In the SNR region of greatest interest for systems with high spectral efficiency, simulation results show that the hybrid DFE offers significant gains compared to a regular DFE or an LE of comparable complexity.
Laboratory Evaluation of Pressure Differential-Based Respirable Dust Detector Tube (2000)

Assessment of exposure to occupational dusts is a first step in reducing exposures to harmful dust concentrations. A new type of respirable dust sampler was developed and compared side-by-side to personal gravimetric samplers in the laboratory. The new sampler correlates filter back pressure with mass accumulation to provide mid-shift- and end-of-shift determinations of cumulative exposure. The sampler uses a small low flow rate pump to draw dust through a small detector tube that contains a porous urethane foam respirable classification section and glass fiber filter that collects respirable dust. Six different coal dusts were aerosolized in a laboratory dust chamber and a total of 119 triplicate observations were obtained. For individual coal types, the correlation coefficients were between 0.87 and 0.97. The precision of the two methods was similar, with the percent relative standard deviation of the personal samplers of 12 percent and the new detector method of 14 percent. For all coal types tested th data were best described by a power function where delta P = 1.43 mass (0.85), with a correlation coefficient of 0.73. The method becomes more accurate at higher dust loadings such that all laboratory data with mass loadings greater than an equivalent concentration of 2 mg/m3 fall within +/- 25 percent of the power function. Assessment of the method under field conditions is in progress.
Quantification of microsurgical tactile perception (2003)

Microsurgery involves the manipulation of delicate membranes and vessels with a required accuracy often on the order of tens of microns, a scale at or near the limit of human positional ability. In addition, forces imposed by the tissue on the surgical tool during these manipulations are exceedingly small. Manual tasks performed using visual feedback alone (i.e., without tactile sensation) have been shown to take longer and be less accurate than tasks performed utilizing both visual and tactile information. Here we validate the hypothesis that retinal surgery is primarily vision based by measuring the magnitude of forces generated during simulated retinal surgery in cadaveric porcine eyes and comparing the results with the magnitude of forces discernable by retinal surgeons. Our goal is to improve microsurgical performance by developing robotic augmentation devices capable of enhancing the surgeon's ability to both position surgical tools and sense the surgical environment. The results of this study are an important guideline for such systems currently under development.
A new single ended sense amplifier for low voltage embedded EEPROM non volatile memories (2003)

A new single ended sense amplifier is presented in this paper. It is based on a very simple direct current-voltage conversion. It has been designed in standard CMOS process for embedded non-volatile memories. Its performances are compared to one of the actually most integrated sense amplifiers, based on differential structures. A 40% faster access time has been obtained at 1.8V.
A semi-active tuned liquid column damper for lateral vibration control of high-rise structures: Theory and experimental verification (2021)

This paper presents a new type of semi-active tuned liquid column damper (S-TLCD) for the lateral vibration control of high-rise civil engineering structures. Analogous to the passive tuned liquid column damper (TLCD), the S-TLCD comprises a U-shaped tank consisting of two vertical columns, which are arranged at a distance from each other and communicating through a horizontal passage. The tank is partially filled with a Newtonian fluid until the liquid reaches a certain level in the columns. In contrast to the passive TLCD, the S-TLCD provides also mechanisms for a continuous adaptation of both its natural frequency and damping behaviour in real-time. In the first part of the paper, the governing equations of the S-TLCD are derived based on the Bernoulli equation of a non-stationary incompressible liquid flow. The natural frequency of the S-TLCD is revealed to depend on the scaled length of the liquid. The scaling amount of the liquid length is formulated in dependence of the cross-sectional area ratios of the tank segments. The mathematical description of the S-TLCD is concluded by providing the state-space representation of a multi-degree-of-freedom structure with several S-TLCDs. In the second part of the paper, the derived natural frequency equation is verified and the proof of concept of the S-TLCD is shown by experimental investigations, which are performed on an S-TLCD model utilizing a test structure and shaking table tests.
<title>Fluorescence lifetime as a new parameter in analytical cytology measurements</title> (1996)

A phase-sensitive flow cytometer has been developed to quantify fluorescence decay lifetimes on fluorochrome-labeled cells/particles. This instrument combines flow cytometry (FCM) and frequency-domain fluorescence spectroscopy measurement principles to provide unique capabilities for making phase-resolved lifetime measurements, while preserving conventional FCM capabilities. Cells are analyzed as they intersect a high-frequency, intensity-modulated (sine wave) laser excitation beam. Fluorescence signals are processed by conventional and phase-sensitive signal detection electronics and displayed as frequency distribution histograms. In this study we describe results of fluorescence intensity and lifetime measurements on fluorescently labeled particles, cells, and chromosomes. Examples of measurements on intrinsic cellular autofluorescence, cells labeled with immunofluorescence markers for cell-surface antigens, mitochondria stains, and on cellular DNA and protein binding fluorochromes will be presented to illustrate unique differences in measured lifetimes and changes caused by fluorescence quenching. This innovative technology will be used to probe fluorochrome/molecular interactions in the microenvironment of cells/chromosomes as a new parameter and thus expand the researchers' understanding of biochemical processes and structural features at the cellular and molecular level.
<title>Photopolymers for holography</title> (1990)

Photosensitive films composed of dye, initiator, acrylic monomers, and polymeric film-forming binder, and their use in recording volume phase transmission and reflection holograms are described. Systematic variation of monomer-binder combinations reveals that the maximum attainable index modulation (hologram efficiency) increases with increasing difference between the refractive indices of monomer and binder. Addition of plasticizer is also useful for increasing index modulation. Thermal and wet chemical processing methods for altering hologram properties are described.
A compact dual standard MIMO antenna system for mobile applications (2017)

In this work, a low profile, wide-band, dual standard, multiple-input-multiple-output (MIMO) antenna system is proposed for mobile applications. The MIMO antenna system consists of 4 monopole antenna elements for 4G standard covering different bands between 1900-3212 MHz and 3517-3712 MHz and 2 linear connected antenna arrays (LCA) for 5G standard covering 25.7-30.50 GHz band at mm-waves. This integrated MIMO antenna system is fabricated on an RO4350 substrate with ε <sub xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">r</sub> equal to 3.5. The dimensions of the board are equal to 115×65×0.76 mm <sup xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">3</sup> which is a typical backplane size of a mobile handset. MIMO performance metrics such as envelope correlation coefficient and isolation are calculated and observed to be 0.16 and 13dB, respectively, at 4G bands and 0.0069 and 20dB at 5G band which shows good MIMO performances.
Fully Automatic Facial Action Recognition in Spontaneous Behavior (2006)

We present results on a user independent fully automatic system for real time recognition of facial actions from the facial action coding system (FACS). The system automatically detects frontal faces in the video stream and codes each frame with respect to 20 action units. We present preliminary results on a task of facial action detection in spontaneous expressions during discourse. Support vector machines and AdaBoost classifiers are compared. For both classifiers, the output margin predicts action unit intensity
Centronuclear myopathies under attack: A plethora of therapeutic targets (2018)

Centronuclear myopathies are a group of congenital myopathies characterized by severe muscle weakness, genetic heterogeneity, and defects in the structural organization of muscle fibers. Their names are derived from the central position of nuclei on biopsies, while they are at the fiber periphery under normal conditions. No specific therapy exists yet for these debilitating diseases. Mutations in the myotubularin phosphoinositides phosphatase, the GTPase dynamin 2, or amphiphysin 2 have been identified to cause respectively X-linked centronuclear myopathies (also called myotubular myopathy) or autosomal dominant and recessive forms. Mutations in additional genes, as RYR1, TTN, SPEG or CACNA1S, were linked to phenotypes that can overlap with centronuclear myopathies. Numerous animal models of centronuclear myopathies have been studied over the last 15 years, ranging from invertebrate to large mammalian models. Their characterization led to a partial understanding of the pathomechanisms of these diseases and allowed the recent validation of therapeutic proof-of-concepts. Here, we review the different therapeutic strategies that have been tested so far for centronuclear myopathies, some of which may be translated to patients.
Use of a Recombinant Envelope Protein Subunit Antigen for Specific Serological Diagnosis of West Nile Virus Infection (2004)

Serological diagnosis of West Nile virus (WNV) infection is complicated by extensive antigenic cross-reactivity with other closely related flaviviruses, such as St. Louis encephalitis virus. Here we describe a recombinant, bacterially expressed antigen equivalent to structural domain III of the WNV envelope protein that has allowed clear discrimination of antibody responses to WNV from those against other related flaviviruses in indirect enzyme-linked immunosorbent assays using standardized control antisera and field-collected samples.
Dewatering of Poor-Quality Bitumen Froth: Induction Time and Mixing Effects (2018)

The impact of mixing conditions on the removal of water and solids from high-water, poor-quality bitumen froth was explored. Naphtha diluent and a demulsifier were added to improve removal of water and solids from bitumen froth. The mixing and subsequent settling of this system were carried out in the confined-impeller stirred tank, a lab-scale mixing test vessel with well-characterized, relatively uniform mixing conditions. A protocol for finding the proper demulsifier dosage at which to study mixing effects was applied successfully. High mixing energy J and the predilution of demulsifier (characterized by its injection concentration IC) improved dewatering and solids removal performance, agreeing with earlier studies in diluted bitumen and bitumen froth of higher quality (Laplante et al. Fuel Process. Technol. 2015, 138, 361–367; Arora, N. Mechanisms of Aggregation and Separation of Water and Solids from Bitumen Froth Using Cluster Size Distribution, 2016). An unexpected finding was that dewatering was significantly delayed in poor-quality froth: it was not detectable until up to 45 min in some cases. This induction time was replicated and was clearly impacted by changes in the mixing conditions.
Feature parameter optimization for seizure detection/prediction (2005)

When dealing with seizure detection/prediction problems, there are three main performance metrics that must be optimized: false positive rate, false negative rate, detection delay or, if the problem is seizure prediction, it is desirable to obtain the greatest prediction time achievable. Tuning specific extracted features to individual patients can lead to improved results. The processing window length is also an important parameter whose optimization may significantly affect performance. In this study we propose an approach for selecting the window length for the particular detection/prediction problem. This approach is applicable to other feature parameters suitable for tuning or optimization.

Negatively stained preparations show that the virus is pleiomorphic. It is fusiform or rod-shaped. In negatively stained preparations, the virion measures 70 to 150 nm at its broadest point and is 250 to 380 nm long. In some virions, a tail-like projection extends from one end. The capsid is apparently composed of rings of subunits in a stacked series. The rings are aligned perpendicular to the longitudinal axis of the capsid. The genome of the virus is a double-stranded DNA molecule which produces at least 22 Hind III fragments. The full length of the DNA is estimated to be longer than 150 kbp. Based on the morphological characteristics and genomic structures of the virus, we confirm that white spot syndrome associated virus (WSSV) is a member of genus NOB (Non-Occluded Baculovirus) of the subfamily Nudibaculovirinae of Baculoviridae, name the present isolate PmNOBIII, and propose the use of WSBV (Baculovirus associated with White Spot syndrome) to indicate PmNOBIII related agents.

Our results show that vaccine formulations containing phytol and PHIS-01 as adjuvants confer a robust and protective immunity against both Gram-negative and Gram-positive bacteria without inducing adverse inflammatory cytokine due to IL-6.
Bacterial Ice Nucleation: A Factor in Frost Injury to Plants (1982)

Heterogeneous ice nuclei are necessary, and the common epiphytic ice nucleation active (INA) bacteria Pseudomonas syringae van Hall and Erwinia herbicola (Löhnis) Dye are sufficient to incite frost injury to sensitive plants at -5 degrees C. The ice nucleation activity of the bacteria occurs at the same temperatures at which frost injury to sensitive plants occurs in nature. Bacterial ice nucleation on leaves can be detected at about -2 degrees C, whereas the leaves themselves, i.e. without INA bacteria, contain nuclei active only at much lower temperatures. The temperature at which injury to plants occurs is predictable on the basis of the ice nucleation activity of leaf discs, which in turn depends on the number and ice nucleation activity of their resident bacteria. Bacterial isolates which are able to incite injury to corn at -5 degrees C are always active as ice nuclei at -5 degrees C. INA bacteria incited frost injury to all of the species of sensitive plants tested.
A new epitaxial lateral overgrowth silicon bipolar transistor (1987)

A new device structure and method of fabricating a silicon bipolar transistor is proposed.

Control-oriented PCCI combustion timing model for a diesel engine utilizing flexible intake valve modulation and high EGR levels (2012)

This paper describes a simple, analytical, control-oriented and physically-based model for prediction of combustion timing during PCCI combustion. The model includes direct dependence on in-cylinder temperature, in-cylinder pressure, and the total in-cylinder O <sub xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">2</sub> mass fraction. It is extensively validated with experimental PCCI data from a multi-cylinder engine with almost exclusively stock hardware (stock pistons, injectors/nozzles, turbocharger, etc.) and variable valve actuation. The results show that across a wide range of input conditions the model predicts the start of combustion (SOC) within ±2°CA of the experimental values for all but one of the 119 data points. The experimental SOC ranges from as early as -19.3°CA to as late as +0.6°CA by heavily exercising the control authority over SOC provided by SOI <sub xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">ecm</sub> , IVC/ECR modulation (ECR ranges from 12:1 to 18:1), and the engine's air-handling system. This PCCI combustion timing model can be coupled with a gas exchange model for control algorithm design.
