Dynamics Modeling of Human–Machine Control Interface for Underwater Teleoperation (2020)

SUMMARY This paper presents an experimental study on new paradigms of haptic-based teleoperated navigation of underwater vehicles. Specifically, the work is focused on investigating the possibility of enhancing the user interaction by introducing haptic cues at the level of the user wrist providing a force feedback that reflects dynamic forces on the remotely operated underwater vehicle. Different typologies of haptic controllers are conceived and integrated with a real-time simulated model of an underwater robotic vehicle. An experimental test is designed to evaluate the usability of the system and to provide information on the global performance during the execution of simple tasks. Experiments are conducted with 7 candidates testing 12 different controllers. Among these, the most effective strategies have been identified and selected on the basis of minimization of errors on the vehicle trajectory and of the quality of the user’s interaction in terms of perceived comfort during operation. Overall, the results obtained with this study underline that haptic navigation control can have a positive influence on the performance of remotely controlled underwater vehicles.
Measuring the psychological construct of control. Discriminant, divergent, and incremental validity of the Shapiro Control Inventory and Rotter's and Wallstons' Locus of Control Scales. (1993)

The psychological construct of control is increasingly thought to be an important variable in psychosomatic medicine, but there are limitations with how it has been measured by previous instruments. The current study details four limitations of previous instruments as a rationale for developing a new multi-faceted, multi-dimensional instrument to measure control, the Shapiro Control Inventory (SCI). Discriminant, divergent, and incremental validity of the SCI is compared with the Rotter's Internal/External Locus of Control Scale and Wallstons' Multidimensional Health Locus of Control Scales on five groups, one normal and four clinical groups (depression, generalized anxiety disorder, borderline personality, and panic disorder). Analysis of variance showed significant differences among populations on each of the nine SCI scales. The majority of these results were highly significant, whereas for Rotter's scale the results were barely significant, and for Wallstons' three scales, not at all significant. Correlations of the SCI scales with Rotter's and Wallstons' scales were small to moderate, but in no case explained more than 15% of the variance. The SCI also provided incremental validity over Rotter's and Wallstons' scales both for sensitivity (clinical versus normal) and specificity (between clinical groups). The discussion section provides suggestions for future research.
Improving the efficiency of PSOVina for protein-ligand docking by two-stage local search (2016)

Protein-ligand docking programs are valuable tools in the modern drug discovery process for predicting the complex structure of a small molecule ligand and the target protein. Often, the configurational search algorithm in the docking tool consists of global search and local search. The former is to explore widely for promising regions in the search space and the latter is to optimize a candidate solution to a local optimum. However, accurate local search methods such as gradient-based Newton methods are very costly. In this investigation, we present a new approach to enhance the time efficiency of a docking program by introducing a two-stage local search method. Given a candidate solution, a rough local search is performed in the first stage to determine the potentiality of the solution. Only if the solution is promising, the second stage with a full local search will be performed. Our method has been realized in the PSOVina docking program and tested on two data sets. The experimental results show that two-stage local search achieves almost 2x speedup to conventional one-stage method, it also enhances the prediction performance of the docking method in terms of increased success rate and RMSD.
Anaerobic Digestion and Acid Hydrolysis of Nitrocellulose (1999)

In military applications, nitrocellulose (NC) based powders are extensively used as propellant in bullets, shells, and various missiles for tube munitions.Residual NC produced during the manufacturing process is composed of insoluble fibers, or "fines" in suspension.Currently, these suspended solids are recovered and reused.However, since the Army expects to terminate the re-use of pit cotton in the near future, there is a need to develop innovative NC treatment and disposal technologies.This study evaluated and demonstrated the potential for the use of acid hydrolysis and anaerobic digestion to treat munitions-grade nitrocellulose.As an alternative treatment, the concept of acid hydrolysis was developed and validated with bench scale tests.NC was hydrolyzed with high strength hydrochloric acid and was converted to glucose.The degradative intermediate and end products were identified and a kinetic model was validated.
Structures and generation mechanisms of paramagnetic centers and absorption bands responsible for Ge-dopedSiO2optical-fiber gratings (1998)

Paramagnetic centers and absorption bands induced by ultraviolet photons in Ge-doped ${\mathrm{SiO}}_{2}$ glass are investigated. Four kinds of samples with different Ge contents were exposed to ultraviolet photons from a KrF excimer laser (5.0 eV), a XeCl excimer lamp (4.0 eV), and a KrCl excimer lamp (5.6 eV). Irradiation with the KrF excimer laser induces two paramagnetic centers, named Ge(1) and Ge(2), in proportion with a decrease in the absorption at 5.1 eV and with an increase in absorption at 4.5 and 5.8 eV. The total density of the induced paramagnetic centers is linearly proportional to each induced change of the three absorption components and their proportionality constants are independent of the Ge content of the samples. The 4.0-eV photons from the XeCl excimer lamp induce only a Ge ${E}^{\ensuremath{'}}$ center, while the 5.6-eV photons from the KrCl excimer lamp induce a Ge(1) besides a Ge ${E}^{\ensuremath{'}}$ center. From these results, Ge(1) and Ge(2) are, respectively, assigned to the Ge electron center (GEC) and the positively charged Ge oxygen-deficient center $(\mathrm{GODC}{)}^{+},$ which donated an electron to the GEC. The oscillator strength of the GODC for the absorption at 5.1 eV was found to be 0.1. From this, it is considered that the GODC that acts as the electron donor is the Ge lone pair center (GLPC). Thermally stimulated luminescence (TSL) is also examined in Ge-doped ${\mathrm{SiO}}_{2}$ glass that was exposed to photons from the KrF excimer laser. The TSL spectrum is very similar to the photoluminescence spectrum that is known to be due to the GLPC's. It was found that the absorption, which was induced by the KrF excimer laser photons, decreases during the TSL measurement and that this decrement of the absorption is proportional to the TSL intensity. As mentioned above, the electrons that are to be trapped to generate the GEC's are released from the GLPC's during the photon irradiation. Then, in its reverse reaction, these electrons are thermally detrapped from the GEC's to regenerate the GLPC's, and the TSL is caused by an electronic de-excitation in such formed GLPC's. To conclude, the TSL phenomenon further validates the assumption that the GLPC is the electron donor to generate the GEC's.
Correlating biodegradation kinetics of 2,3,7,8-tetrachlorodibenzo-p-dioxin to the dynamics of microbial communities originating from soil in Vietnam contaminated with herbicides and dioxins (2022)

We studied the succession of bacterial communities during the biodegradation of 2,3,7,8-tetrachlorodibenzo-p-dioxin (2,3,7,8-TCDD). The communities originated from a mesocosm with soil from Bien Hoa airbase in Vietnam heavily contaminated with herbicides and dioxins. They were grown in defined media with different carbon and Gibbs energy sources and 2,3,7,8-TCDD. Cultures with dimethyl sulfoxide (DMSO) as the sole carbon and energy source degraded about 95% of 2,3,7,8-TCDD within 60 days of cultivation. Those with an additional 1 mM of vanillin did that in roughly 90 days. Further 16S rRNA gene amplicon sequencing showed that the increase in relative abundance of members belonging to the genera <i>Bordetella</i>, <i>Sphingomonas</i>, <i>Proteiniphilum</i>, and <i>Rhizobium</i> correlated to increased biodegradation of 2,3,7,8-TCDD in these cultures. A higher concentration of vanillin slowed down the biodegradation rate. Addition of alternative carbon and Gibbs energy sources, such as amino acids, sodium lactate and sodium acetate, even stopped the degradation of 2,3,7,8-TCDD completely. Bacteria from the genera <i>Bordetella</i>, <i>Achromobacter</i>, <i>Sphingomonas</i> and <i>Pseudomonas</i> dominated most of the cultures, but the microbial profiles also significantly differed between cultures as judged by non-metric multidimensional scaling (NMDS) analyses. Our study indicates that 2,3,7,8-TCDD degradation may be stimulated by bacterial communities preadapted to a certain degree of starvation with respect to the carbon and energy source. It also reveals the succession and abundance of defined bacterial genera in the degradation process.
In vivo analysis of metal distribution and expression of metal transporters in rice seed during germination process by microarray and X-ray Fluorescence Imaging of Fe, Zn, Mn, and Cu (2009)

To investigate the flow of the metal nutrients iron (Fe), zinc (Zn), manganese (Mn), and copper (Cu) during rice seed germination, we performed microarray analysis to examine the expression of genes involved in metal transport. Many kinds of metal transporter genes were strongly expressed and their expression levels changed during rice seed germination. We found that metal transporter genes such as ZIP family has tendency to decrease in their expressions during seed germination. Furthermore, imaging of the distribution of elements (Fe, Mn, Zn, and Cu) was carried out using Synchrotron-based X-ray microfluorescence at the Super Photon ring-8 GeV (SPring-8) facility. The change in the distribution of each element in the seeds following germination was observed by in vivo monitoring. Iron, Mn, Zn, and Cu accumulated in the endosperm and embryos of rice seeds, and their distribution changed during rice seed germination. The change in the patterns of mineral localization during germination was different among the elements observed.
Carbon Adsorbents from Polycarbonate Pyrolysis Char Residue: Hydrogen and Methane Storage Capacities (2010)

The pyrolysis of bisphenol A polycarbonate (PC) can be a solution to chemical recycling of this widely used polymer, which, once it is used, losses its value. The char residue produced in the pyrolysis constitutes more than a quarter of the weight of the PC pyrolyzed and is considered one of the drawbacks of the recycling process. The hypothesis that such char can become a potential good precursor for selective carbon adsorbents, attending to the high carbon content and regular structure of the polymer, is worth considering. Therefore, this work analyses the physical and chemical activation of such char to produce selective high-capacity carbon adsorbents for acting as gas storage solutions. According to an exhaustive textural characterization, the activated carbons prepared are eminently microporous, with a significant volume of narrow micropores, which make them efficient for the adsorption of light energy-carrier gases, such as methane and hydrogen. The methane and hydrogen uptakes measured are in the highest end of those reported for physisorption storage processes and seem to be only related to micropore textural parameters. Surprisingly, a certain amount of very narrow micropores (totally inaccessible to nitrogen molecules at 77 K and showing diffusion restrictions for CO2 adsorption at 273 K, hence, very difficult to characterize) are already present in the char and prove to be effective in hydrogen adsorption.
COMBINED EFFECTS OF SUBCOOLING AND SURFACE ORIENTATION ON POOL BOILING OF HFE-7100 FROM A SIMULATED ELECTRONIC CHIP (2003)

The effects of orientation and subcooling on pool boiling of the HFE-7100 dielectric liquid near atmospheric pressure (0.085 MPa) from a 10 × 10 mm smooth copper surface are investigated experimentally. Results are obtained for inclination angles θ = 0° (upward-facing), 30°, 60°, 90°, 120°, 150°, and 180° (downward-facing) and liquid subcoolings ΔTsub = 0, 10, 20, and 30 K. Increasing θ decreases the saturation nucleate boiling heat flux at high surface superheats (ΔTsat > 20 K), but increases it only slightly at lower surface superheats. The critical heat flux (CHF) decreases slowly with increasing θ from 0° to 90°, and then deceases faster with increasing θ to 180°. CHF increases linearly with increased subcooling, but the rate increases from 0.016 K−1 at 0° to 0.048 K−1 at 180°. At θ = 0° and ΔTsub = 30 K, CHF is ∼ 36 W/cm2 and 24.45 W/cm2 for saturation boiling, while at θ = 180° CHF = 10.85 W/cm2 at ΔTsub = 30 K and only 4.30 W/cm2 at saturation. The developed correlation for CHF of HFE-7100, as a function of θ and ΔTsub, is within ±10% of the present data. The recorded still photographs of the boiling surface in the experiments illustrate the effects of liquid subcooling and surface orientation at different nucleate boiling heat fluxes and surface superheats on vapor bubble accumulation and/or induced mixing at the surface.
14-Carbon demonstrates that some illegal ivory is being taken from government stockpiles (2022)

The 14-carbon in animal tissues records the time that the tissues are formed; since the 1960s, using the "bomb curve" for <sup>14</sup>C, the age of animal death can be determined accurately. Using animal tissue samples of known collection and formation dates for calibration, we determine the age of ivory samples from four ivory seizures made by law enforcement agencies between 2017 and 2019. The <sup>14</sup>C measurements from these seizures show that most ivory in the illegal wildlife trade is from animals from recent poaching activities. However, one seizure has a large fraction of ivory that is more than 30 y old, consistent with markings on the tusks indicating they were derived from a government stockpile.

Different Polyphenolic Components of Soft Fruits Inhibit α-Amylase and α-Glucosidase (2005)

Polyphenol-rich extracts from soft fruits were tested for their ability to inhibit alpha-amylase and alpha-glucosidase. All extracts tested caused some inhibition of alpha-amylase, but there was a 10-fold difference between the least and most effective extracts. Strawberry and raspberry extracts were more effective alpha-amylase inhibitors than blueberry, blackcurrant, or red cabbage. Conversely, alpha-glucosidase was more readily inhibited by blueberry and blackcurrant extracts. The extent of inhibition of alpha-glucosidase was related to their anthocyanin content. For example, blueberry and blackcurrant extracts, which have the highest anthocyanin content, were the most effective inhibitors of alpha-glucosidase. The extracts most effective in inhibiting alpha-amylase (strawberry and raspberry) contain appreciable amounts of soluble tannins. Other tannin-rich extracts (red grape, red wine, and green tea) were also effective inhibitors of alpha-amylase. Indeed, removing tannins from strawberry extracts with gelatin also removed inhibition. Fractionation of raspberry extracts on Sephadex LH-20 produced an unbound fraction enriched in anthocyanins and a bound fraction enriched in tannin-like polyphenols. The unbound anthocyanin-enriched fraction was more effective against alpha-glucosidase than the original extract, whereas the alpha-amylase inhibitors were concentrated in the bound fraction. The LH-20 bound sample was separated by preparative HPLC, and fractions were assayed for inhibition of alpha-amylase. The inhibitory components were identified as ellagitannins using LC-MS-MS. This study suggests that different polyphenolic components of fruits may influence different steps in starch digestion in a synergistic manner.
Molecular dynamics simulation of the capillary leveling of a glass-forming liquid (2018)

Motivated by recent experimental studies probing i) the existence of a mobile\nlayer at the free surface of glasses, and ii) the capillary leveling of polymer\nnanofilms, we study the evolution of square-wave patterns at the free surface\nof a generic glass-forming binary Lennard-Jones mixture over a wide temperature\nrange, by means of molecular dynamics simulations. The pattern's amplitude is\nmonitored and the associated decay rate is extracted. The evolution of the\nlatter as a function of temperature exhibits a crossover between two distinct\nbehaviours, over a temperature range typically bounded by the glass-transition\ntemperature and the mode-coupling critical temperature. Layer-resolved analysis\nof the film particles' mean-squared displacements further shows that diffusion\nat the surface is considerably faster than in the bulk, below the\nglass-transition temperature. The diffusion coefficient of the surface\nparticles is larger than its bulk counterpart by a factor that reaches 105 at\nthe lowest temperature studied. This factor decreases upon heating, in\nagreement with recent experimental studies.\n
A Block-level Security based on Hierarchical Logical Volume of Fibre Channel RAID (2006)

Block-level security provides the lowest level security for storage devices. In this paper, we propose a block-level security based on hierarchical logical volume of FC RAID. Using the hierarchical logical volume, a group of physical disks can be mapped to a uniform logical storage space and two encrypt/decrypt algorithms can be applied to different logic volumes.
Lipogenesis and innate immunity in hepatocellular carcinoma cells reprogrammed by an isoenzyme switch of hexokinases (2020)

Abstract During the cancerous transformation of normal hepatocytes into hepatocellular carcinoma (HCC), the enzyme catalyzing the first rate-limiting step of glycolysis, namely the glucokinase (GCK), is replaced by the higher affinity isoenzyme, hexokinase 2 (HK2). The transcriptomic analysis of HCC tumors shows that highest expression level of HK2 in tumor lesions is inversely correlated to GCK expression, and is associated to poor prognosis for patient survival. To further explore functional consequences of the GCK-to-HK2 isoenzyme switch occurring during carcinogenesis, HK2 was knocked-out in the HCC cell line Huh7 and replaced by GCK , to generate the Huh7- GCK + / HK2 − cell line. HK2 knockdown and GCK expression rewired central carbon metabolism, stimulated mitochondrial respiration and restored essential metabolic functions of normal hepatocytes such as lipogenesis, VLDL secretion, glycogen storage. It also reactivated innate immune responses and sensitivity to natural killer cells, showing that consequences of the HK switch extend beyond metabolic reprogramming.
Bootstrap loading using TFTP (1984)

It is often convenient to be able to bootstrap a computer system from a communications network. This RFC proposes the use of the IP TFTP protocol for bootstrap loading in this case.
Rat ATP citrate-lyase. Molecular cloning and sequence analysis of a full-length cDNA and mRNA abundance as a function of diet, organ, and age. (1990)

ATP citrate-lyase is the primary enzyme responsible for the synthesis of cytosolic acetyl-CoA in many tissues. We have isolated a full-length cDNA copy of 4.3 kilobase pairs encoding the ATP-citrate lyase mRNA by screening rat liver cDNA library using oligonucleotide probes designed from peptide sequences obtained from the purified rat enzyme. Expression of this cDNA in bacteria, followed by immunoblotting with antibody directed against the ATP citrate-lyase, further demonstrated the identity of this clone. Nucleic acid sequence data indicate that the cDNA contains the complete coding region for the enzyme, which is 1100 amino acids in length with a calculated molecular weight of 121,293. RNA blot analysis indicated an mRNA species of about 4.3 kilobase pairs in livers of chow-fed rats. Rats maintained on low fat, high carbohydrate diets exhibited a striking increase (50-fold) in the level of liver ATP citrate-lyase mRNA as compared with the control animals maintained on a normal diet. The tissue distribution of this mRNA in chow-fed animals revealed a relatively high abundance of the message in liver and adrenal, moderate levels were found in lung, brain, and large intestine with only trace amounts of the message in small intestine, stomach, testis, spleen, pancreas, kidney, and heart. During rat development, the ATP citrate-lyase mRNA was relatively high in the liver at parturition, followed by a reduction in its level during suckling. Higher amounts of the mRNA were detected again in adult animals. The isolation and characterization of the mRNA for ATP citrate-lyase will allow further studies on the reaction mechanism and metabolic regulation of this key enzyme in lipogenesis and cholesterogenesis.

Controllable hand deformation from sparse examples with rich details (2011)

Recent advances in laser scanning technology have made it possible to faithfully scan a real object with tiny geometric details, such as pores and wrinkles. However, a faithful digital model should not only capture static details of the real counterpart but also be able to reproduce the deformed versions of such details. In this paper, we develop a data-driven model that has two components respectively accommodating smooth large-scale deformations and high-resolution deformable details. Large-scale deformations are based on a nonlinear mapping between sparse control points and bone transformations. A global mapping, however, would fail to synthesize realistic geometries from sparse examples, for highly-deformable models with a large range of motion. The key is to train a collection of mappings defined over regions locally in both the geometry and the pose space. Deformable fine-scale details are generated from a second nonlinear mapping between the control points and per-vertex displacements. We apply our modeling scheme to scanned human hand models. Experiments show that our deformation models, learned from extremely sparse training data, are effective and robust in synthesizing highly-deformable models with rich fine features, for keyframe animation as well as performance-driven animation. We also compare our results with those obtained by alternative techniques.
