THz-Range Optical Frequency Shifter for Dual Polarization WDM Signals Using Frequency Conversion in Fiber (2017)

We propose an optical frequency shifter for dual-polarization signals using frequency conversion in fiber. The proposed optical frequency shifter is achieved by transmitting input signal combined with two orthogonally polarized continuous wave pump lights through a nonlinear fiber and a polarizer. In the scheme, a polarization switched and frequency shifted copy of an original signal is generated in the nonlinear fiber and the subsequent polarizer removes the original signal in a wavelength independent fashion. It allows a fractional bandwidth shift, in which the shifted signal is overlapped with the original signal. We achieve THz range frequency shift with original signal suppression without an optical filter by using a polarization diversity loop. A polarization beam splitter is used as a splitter and a combiner of the loop as well as for original signal rejection. A contention resolution of two dual-polarization 400-Gb/s superchannels is demonstrated by applying the optical frequency shifter with acceptable in-band crosstalk. For any-to-any optical frequency shift, wavelength arrangement for pumps and required zero dispersion and dispersion slope of nonlinear fibers are numerically simulated.
Registration of ‘CLJ01’ Rice (2019)

‘CLJ01’ (Reg. No. CV‐152, PI 687326), a Clearfield (BASF) long‐grain aromatic (Jazzman) rice ( Oryza sativa L.) cultivar, was developed by the Louisiana State University Agricultural Center at the H. Rouse Caffey Rice Research Station near Crowley, LA, and approved for release by the director of the Louisiana Agricultural Experiment Station in 2018. CLJ01 is the first aromatic rice cultivar to be released for use with the Clearfield rice production systems. CLJ01 was derived from the cross ‘Jazzman’/08CLR004//RU0802146/3/RU1002146, made 2010 and advanced in 2014 as an F 4 row selection. Preliminary testing in 2015 indicated high yield potential and favorable agronomic and grain characteristics. CLJ01 was evaluated across 27 trials in eight locations in 2016–2017. Three high‐yielding commercial Clearfield cultivars (‘CL111’, ‘CL151’, and ‘CL153’) and two commercial aromatic cultivars (‘Della‐2’ and ‘Jazzman‐2’) were included as checks. Grain yield of CLJ01 was 7.95 t ha −1 compared with 8.16 t ha −1 for CL111, 9.18 t ha −1 for CL151, 8.88 t ha −1 for CL153, 7.35 t ha −1 for Della‐2, and 6.15 t ha −1 for Jazzman‐2. The leaves, lemma, and palea are glabrous, the apiculus is has a purple color, and the grain is aromatic. CLJ01 is moderately susceptible to blast and susceptible to sheath blight, bacterial panicle blight, narrow brown leaf spot, and the physiological disorder straighthead.
Thermal Modeling of Extreme Heat Flux Microchannel Coolers for GaN-on-SiC Semiconductor Devices (2016)

Gallium nitride (GaN) high-electron-mobility transistors (HEMTs) dissipate high power densities which generate hotspots and cause thermomechanical problems. Here, we propose and simulate GaN-based HEMT technologies that can remove power densities exceeding 30 kW/cm2 at relatively low mass flow rate and pressure drop. Thermal performance of the microcooler module is investigated by modeling both single- and two-phase flow conditions. A reduced-order modeling approach, based on an extensive literature review, is used to predict the appropriate range of heat transfer coefficients associated with the flow regimes for the flow conditions. Finite element simulations are performed to investigate the temperature distribution from GaN to parallel microchannels of the microcooler. Single- and two-phase conjugate computational fluid dynamics (CFD) simulations provide a lower bound of the total flow resistance in the microcooler as well as overall thermal resistance from GaN HEMT to working fluid. A parametric study is performed to optimize the thermal performance of the microcooler. The modeling results provide detailed flow conditions for the microcooler in order to investigate the required range of heat transfer coefficients for removal of heat fluxes up to 30 kW/cm2 and a junction temperature maintained below 250 °C. The detailed modeling results include local temperature and velocity fields in the microcooler module, which can help in identifying the approximate locations of the maximum velocity and recirculation regions that are susceptible to dryout conditions.
Asymmetric tensor visualization with glyph and hyperstreamline placement on 2D manifolds (2009)

Asymmetric tensor fields present new challenges for visualization techniques such as hyperstreamline placement and glyph packing. This is because the physical behaviors of the tensors are fundamentally different inside real domains where eigenvalues are real and complex domains where eigenvalues are complex. We present a hybrid visualization approach in which hyperstreamlines are used to illustrate the tensors in the real domains while glyphs are employed for complex domains. This enables an effective visualization of the flow patterns everywhere and also provides a more intuitive illustration of elliptical flow patterns in the complex domains. The choice of the types of representation for different types of domains is motivated by the physical interpretation of asymmetric tensors in the context of fluid mechanics, i.e., when the tensor field is the velocity gradient tensor. In addition, we encode the tensor magnitude to the size of the glyphs and density of hyperstreamlines. We demonstrate the effectiveness of our visualization techniques with real-world engine simulation data.

American ginseng has a neutral effect on blood pressure in individuals with hypertension (2004)

There are continual commentaries stating that ginseng elevates blood pressure (BP). This stems from the findings of an early observational study, and not from randomized-controlled-trials. Currently, there is a paucity of data concerning ginseng's effect on BP. Since many individuals with hypertension use ginseng, this herb's effect on BP needs to be clinically scrutinized.
A Rapid Image Approximation for Keypatches Building (2009)

A new type of local features with visual semantics, keypatches, was proposed to improve performances of image retrieval methods. These features are obtained by approximating the content of scanning windows using the predefined geometrical patterns. To build keypatches quickly, this paper proposes a new approximation based on a novel compact gradient mapping table (CGMT). The method includes two stages. First, the approximation candidates can be obtained quickly by constructing and looking up the compact gradient mapping table based on the distribution sharing of the contours characteristics of the patterns. Then, Hough transform needs to be applied only in a very small parameter space defined by the candidates for the final approximation. To demonstrate the effectiveness of the proposed method, we have approximated 1628 image patches from 100 images. Results show the proposed method significantly outperforms the previous Hough transform-based approximation in speed with a very small accuracy loss.

A consistent algorithm to fill triangles and triangular patches (1986)

In this paper an algorithm is described for filling triangles in 3D. Since this algorithm uses integer arithmetic only, it is not hampered by inconsistencies that normally arise due to finite machine precision. Moreover, the same algorithm is used for both curved and flat triangular patches.
Holosystolic versus mid-late systolic mitral regurgitation: Differences in characteristics and long-term outcomes in patients undergoing exercise echocardiography (2013)

Purpose: Significant mitral regurgitation (MR) may be holosystolic (HS) or mid-late systolic (MLS) in duration; with differences in volumetric impact on left ventricle. We sought to assess long-term outcomes of patients with myxomatous MR undergoing exercise echocardiography (execho), based on MLS vs HS MR. Methods: We included 609 consecutive patients (59±14 years, 67% men) with ≥3+ myxomatous MR undergoing execho. MLS MR was defined as late MR in systole, relative to valve opening spikes (and/or QRS complex) on continuous-wave Doppler images, while HS MR occurred throughout systole. Clinical data was recorded. Composite events of death, myocardial infarction, stroke, & admission for heart failure were recorded. Results: There were 51 primary events during 6±3 years of follow up (398 MV surgeries, 0% operative mortality). Comparative and outcome results are summarized in the table. Table 1 Age was incorporated in predicted metabolic equivalents and was not added to the multivariable model. LV, Left Ventricular; CI, Confidence Interval. Conclusion: In patients with ≥3+ myxomatous MR undergoing execho, holosystolic MR (despite shorter time to surgery), atrial fibrillation/flutter and lower achieved % age & gender predicted metabolic equivalents were associated with worse outcomes.
Data-driven clustering in emotional space for affect recognition using discriminatively trained LSTM networks (2009)

In today's affective databases speech turns are often labelled on a continuous scale for emotional dimensions such as valence or arousal to better express the diversity of human affect.However, applications like virtual agents usually map the detected emotional user state to rough classes in order to reduce the multiplicity of emotion dependent system responses.Since these classes often do not optimally reflect emotions that typically occur in a given application, this paper investigates data-driven clustering of emotional space to find class divisions that better match the training data and the area of application.Thereby we consider the Belfast Sensitive Artificial Listener database and TV talkshow data from the VAM corpus.We show that a discriminatively trained Long Short-Term Memory (LSTM) recurrent neural net that explicitly learns clusters in emotional space and additionally models context information outperforms both, Support Vector Machines and a Regression-LSTM net.
Photoluminescence fatigue effect in luminescent porous silicon induced by photosensitized molecular oxygen (2005)

We report on the mechanism of photodegradation of hydrogenated porous silicon luminescence in ambients containing molecular oxygen. Energy transfer from excitons confined in silicon nanocrystals assembling porous silicon layers to molecular oxygen results in the generation of highly chemically reactive singlet oxygen molecules. Their subsequent interaction with the hydrogenated surface of silicon nanocrystals results in its photooxidation and creation of additional nonradiative defects, i.e. the luminescence fatique effect.

Cytological studies on the Ehrlich ascites tumor before and after infection with Bunyamwera virus. (2003)

Summary 1.Several features of the morphology and cytochemistry of the Ehrlich ascites tumor cell have been analyzed. 2.The occurrence of nuclear budding or amitotic nuclear division and the development of acidophil intranuclear bodies from the nuclear parachromatin have been described. These bodies are only rarely observed in the uninfected tumor cells, and they have been shown to be chemically and functionally related to nucleoli; it is proposed to call them pseudonucleoli or parachromatin bodies. 3.Bunyamwera virus infection of the Ehrlich ascites tumor results in a selective destruction of the tumor cells. The destructive process involves the intermitotic phase of the cell; it is characterized by the development of prominent pseudonucleoli in a large proportion of infected cells and by the occurrence of multiple nuclear budding similar to, but more pronounced than, that which is occasionally observed in the uninfected tumor cell.

Heat Release Design Method for HCCI in Diesel Engines (2005)

&lt;div class="htmlview paragraph"&gt;A simple thermodynamically based engine design tool is developed to allow engine designers to start with the engine peak pressure limit, desired IMEP, and restraints on rate of pressure rise and thus generate an idealized Wire-Frame cylinder pressure cycle. After conversion into crank-angle based pressures, the apparent heat release rate (AHRR) is generated. The resulting AHRR&lt;span class="xref"&gt;&lt;sup&gt;1&lt;/sup&gt;&lt;/span&gt; represents an idealized heat release rate which is &lt;i&gt;required&lt;/i&gt; to achieve the engine performance goals. This target AHRR is thus known prior to engine testing and serves as a guide to HCCI combustion test engineers.&lt;/div&gt; &lt;div class="htmlview paragraph"&gt;Using the Wire-Frame cycle tool, the ideal heat release rate for HCCI combustion is identified. For low IMEP, this is a single mode HRR centered at TDC. However, for medium and high loads, a second mode of combustion is required to achieve maximum efficiency and retain the benefits of HCCI combustion. The second combustion mode ramps up to maintain the cylinder pressure at the desired firing pressure.&lt;/div&gt; &lt;div class="htmlview paragraph"&gt;Based upon the indications of the Wire-Frame HRR design tool, a few methods are identified and explored which allow higher IMEP from HCCI combustion. Reducing the engine compression ratio and slowing the rate of combustion are practical means to increase the IMEP from single mode HCCI combustion, however, with an efficiency penalty.&lt;/div&gt; &lt;div class="htmlview paragraph"&gt;Analysis of results from the model indicate that achieving full load IMEP in a practical engine may require the development of a two-stage combustion process, with HCCI serving the first stage.&lt;/div&gt;
Emerging Semiconductor Materials for Direct Photoelectochemical Water Splitting (2015)

High-efficiency solar-to-fuel energy conversion can be achieved using direct semiconductor-liquid junctions in a photoelectrochemical (PEC) device consisting of an n-type photoanode in tandem with a p-type photocathode. However, the development of high-performance, stable and inexpensive photoelectrodes are needed to make PEC devices economically viable. In this presentation an overview and the state-of-the-art of this technology including economic considerations is given. In addition, our group’s progress in the development of economically-prepared, high performance photoelectrodes will be discussed along with the application toward overall PEC water splitting tandem cells. Specifically, how the use of scalable solution-processing techniques (e.g. colloidal processing of nanoparticles or sol-gels) leads to limitations in charge transport and charge transfer in the resulting thin-film photoelectrode will be examined. Strategies to overcome these limitations such as using charge extraction buffer layers, catalysts, annealing/doping and nanoparticle self-assembly will be additionally presented. Materials of interest are delafossite CuFeO 2 , CZTS, CIGS, CdS, organic (conjugated) semiconductors and 2D-layered MoS 2 and WSe 2 .
North American Clovis Point Form and Performance II: An Experimental Assessment of Point, Haft, and Shaft Durability (2021)

This study presents the results of an experimental assessment of Clovis projectile durability, or the ability of Clovis point forms and their hafts to withstand impact damage. This work is the second contribution in a series of experimental studies aimed at shedding light on the functional performance of distinct Clovis point forms. For this experiment we fired seven replica Clovis point forms, representing the average and extremes of observed Clovis form, into wood boards until damaged. The resulting damage to the point, haft lashings, and shaft were recorded on each of the 203 specimens. Statistical comparison of the damage indicated differences among the point forms in the amount of damage to the points, haft lashings, and shafts. We show that these results indicate a broad inverse relationship with penetration capability, suggesting a functional trade-off that may have influenced Paleoindian point design.
2P1-F18 Robust Stereo System Considering Reliability of Object Position with Camera Vibration (2010)

This study aims to establish a Robust sensor system by considering a camera vibration. In stereo measurement, we cam approximate the distribution of the measurement error in image by using uniform distribution. Therefore, the parameters of the distribution of the measurement error are the mean value μ and the standard deviation σ, while the amplitude A and the frequency F are regarded as the parameters of the camera vibration. In order to verify relationships between the parameters with regard to the distribution of the measurement error and the parameters of the camera vibration, we performed an experiment using a vibration testing system. By the result, we can establish the measurement error model. Moreover, we defined the existing probability of the object by using the parameters of the measurement error. Additionally, in order to be minimized the errors, we proposed a variable baseline method. We verified effect of the variable baseline method.
216 EMBRYONIC AND INDUCED PLURIPOTENT STEM CELLS ANALOGOUS TO INNER CELL MASS-DERIVED LIF-DEPENDENT MOUSE EMBRYONIC STEM CELLS ESTABLISHED FROM THE DOMESTIC PIG, SUS SCROFA (2011)

Authentic embryonic stem cells (ESC) may never have been successfully derived from the inner cell mass (ICM) of pig and other ungulates, despite over 25 years of effort. Recently, porcine induced pluripotent stem cells (piPSC) were generated by reprogramming somatic cells with a combination of four factors OCT4, SOX2, KLF4 and c-MYC (OSKM) delivered by lentiviral transduction. The established piPSC are analogous to FGF2-dependent human (h) ESC and murine “epiblast stem cells,” and are likely to advance swine as a model in biomedical research. Here, we report for the first time, the establishment of LIF-dependent, so called naïve type pluripotent stem cells (1) from the inner cell mass (ICM) of porcine blastocysts by up-regulating the expression of KLF4 and POU5F1; and (2) from umbilical cord mesenchyme (Wharton's jelly) by transduction with OSKM factors and subsequent culture in the presence of LIF-based medium with inhibitors that substitute for low endogenous expression of c-MYC and KLF4 and promote pluripotency. The 2 compounds that have been used in this study are, CHIR99021 (CH), which substitutes c-MYC by inhibiting GSK3B and activating WNT signalling and Kenpaullone (KP), which inhibits both GSK3B and CDK1 and supplants KLF4 function. The lentiviral vectors employed for introducing the re-programming genes were modified for doxycycline-mediated induction of expression (tet-on) and are ‘floxed’ for Cre-mediated recombination and removal of transgenes following complete reprogramming. Two LIF-dependent cell lines have been derived from the ICM cells of late d 5.5 in vitro produced blastocysts and four from umbilical cord mesenchyme recovered from fetuses at d 35 of pregnancy. The derived stem cell lines are alkaline phosphatase-positive, resemble mouse embryonic stem cells in colony morphology, cell cycle interval, transcriptome profile and expression of pluripotent markers, such as POU5F1, SOX2 and surface marker SSEA1. They are dependent on LIF signalling for maintenance of pluripotency, can be cultured over extended passage (&amp;gt;50) with no senescence. Of importance, the ICM-derived lines have been successful in their ability to form teratomas. The cells could be cultured in feeder free conditions on a synthetic matrix in the presence of chemically defined medium and can be coaxed to differentiate under xeno-free conditions. Currently, the piPSC lines are being investigated for their ability to give rise to teratomas and to produce a live offspring by nuclear transfer.
