Analyzing Absorption Backgrounds in Single-Walled Carbon Nanotube Spectra (2011)

The sources of broad backgrounds in visible-near-IR absorption spectra of single-walled carbon nanotube (SWCNT) dispersions are studied through a series of controlled experiments. Chemical functionalization of nanotube sidewalls generates background absorption while broadening and red-shifting the resonant transitions. Extensive ultrasonic agitation induces a similar background component that may reflect unintended chemical changes to the SWCNTs. No major differences are found between spectral backgrounds in sample fractions with average lengths between 120 and 650 nm. Broad background absorption from amorphous carbon is observed and quantified. Overlapping resonant absorption bands lead to elevated backgrounds from spectral congestion in samples containing many SWCNT structural species. A spectral modeling method is described for separating the background contributions from spectral congestion and other sources. Nanotube aggregation increases congestion backgrounds by broadening the resonant peaks. Essentially no background is seen in sorted pristine samples enriched in a single semiconducting (n,m) species. By contrast, samples enriched in mixed metallic SWCNTs show broad intrinsic absorption backgrounds far from the resonant transitions. The shape of this metallic background component and its absorptivity coefficient are quantitatively assessed. The results obtained here suggest procedures for preparing SWCNT dispersions with minimal extrinsic background absorptions and for quantifying the remaining intrinsic components. These findings should allow improved characterization of SWCNT samples by absorption spectroscopy.
The aorticorenal ganglion and its role in renal innervation (1968)

Abstract A detailed dissection of the renal plexus and the aorticorenal area was carried out in 57 adult cadavers (32 males and 25 females). This study showed that the aorticorenal ganglia may be located anywhere in the general area of the junction of the renal arteries with the aorta. These ganglia were found to be partly fused with the celiac ganglion in 4% on the right side and in 12% on the left. All three thoracic splanchnic nerves (greater, lesser, and least) may have rami which terminate in the aorticorenal ganglia. The least splanchnic terminated in the aorticorenal ganglion more often than the other nerves when the ganglion was located inferior to the renal artery. In this location, the first lumbar splanchnic nerve also may terminate in the aorticorenal ganglion. The aorticorenal ganglia also had connections with the renal plexus, inermesenteric nerves, celiac and superior mesenteric plexuses, adrenal gland, and possibly with the spermatic and ovarian plexuses through the renal plexus. By using the silver impregnation technique of Holmes, we found the aorticorenal ganglia to have a role in renal innervation. When these ganglia were unilaterally removed from a series of 14 cats, a definite reduction of nerve fibers associated with the tubules of the renal cortex, and to lesser extent, with the renal blood vessels, was observed. Most nerve endings were associated with the proximal convoluted tubules, but a few were observed in the glomeruli.
Meandering based parallel 3DRS algorithm for the multicore era (2010)

This paper presents a method to parallelize the meandering based 3D recursive search (3DRS) motion estimation algorithm used in scan-rate up-conversion. The proposed algorithm is scalable and can easily be mapped to multiple processing units such as multithreaded processors, multicores and/or co-processors in order to cope up with the increasingly hard to meet real time requirements of next generation video devices. Experiments show that the picture quality of the proposed parallel 3DRS algorithm is as good as the original non-parallelized algorithm for most video sequences.

A Novel Tomato Fusarium Wilt Tolerance Gene (2018)

The reduced mycorrhizal colonization (<i>rmc</i>) tomato mutant is unable to form mycorrhiza and is more susceptible to Fusarium wilt compared with its wild-type isogenic line 76R. The <i>rmc</i> mutant has a chromosomal deletion affecting five genes, one of which is similar to <i>CYCLOPS.</i> Loss of this gene is responsible for non-mycorrhizality in <i>rmc</i> but not enhanced Fusarium wilt susceptibility. Here, we describe assessment of a second gene in the <i>rmc</i> deletion, designated <i>Solyc08g075770</i> that is expressed in roots. Sequence analyses show that <i>Solyc08g075770</i> encodes a small transmembrane protein with putative phosphorylation and glycosylation sites. It is predicted to be localized in the plasma membrane and may function in transmembrane ion transport and/or as a cell surface receptor. Complementation and knock-out strategies were used to test its function. Some putative CRISPR/Cas-9 knock-out transgenic events exhibited Fusarium wilt susceptibility like <i>rmc</i> and some putative complementation lines were 76R-like, suggesting that the tomato <i>Solyc08g075770</i> functions in Fusarium wilt tolerance. This is the first study to demonstrate that <i>Solyc08g075770</i> is the contributor to the <i>Tfw</i> locus, conferring tolerance to Fusarium wilt in 76R which was lost in <i>rmc.</i>
<i>EGLN1</i> involvement in high-altitude adaptation revealed through genetic analysis of extreme constitution types defined in Ayurveda (2010)

It is being realized that identification of subgroups within normal controls corresponding to contrasting disease susceptibility is likely to lead to more effective predictive marker discovery. We have previously used the Ayurvedic concept of Prakriti, which relates to phenotypic differences in normal individuals, including response to external environment as well as susceptibility to diseases, to explore molecular differences between three contrasting Prakriti types: Vata, Pitta, and Kapha. EGLN1 was one among 251 differentially expressed genes between the Prakriti types. In the present study, we report a link between high-altitude adaptation and common variations rs479200 (C/T) and rs480902 (T/C) in the EGLN1 gene. Furthermore, the TT genotype of rs479200, which was more frequent in Kapha types and correlated with higher expression of EGLN1, was associated with patients suffering from high-altitude pulmonary edema, whereas it was present at a significantly lower frequency in Pitta and nearly absent in natives of high altitude. Analysis of Human Genome Diversity Panel-Centre d'Etude du Polymorphisme Humain (HGDP-CEPH) and Indian Genome Variation Consortium panels showed that disparate genetic lineages at high altitudes share the same ancestral allele (T) of rs480902 that is overrepresented in Pitta and positively correlated with altitude globally (P < 0.001), including in India. Thus, EGLN1 polymorphisms are associated with high-altitude adaptation, and a genotype rare in highlanders but overrepresented in a subgroup of normal lowlanders discernable by Ayurveda may confer increased risk for high-altitude pulmonary edema.
High-precision vision-based mobile augmented reality system for context-aware architectural, engineering, construction and facility management (AEC/FM) applications (2013)

Abstract Background Many context-aware techniques have been proposed to deliver cyber-information, such as project specifications or drawings, to on-site users by intelligently interpreting their environment. However, these techniques primarily rely on RF-based location tracking technologies (e.g., GPS or WLAN), which typically do not provide sufficient precision in congested construction sites or require additional hardware and custom mobile devices. Method This paper presents a new vision-based mobile augmented reality system that allows field personnel to query and access 3D cyber-information on-site by using photographs taken from standard mobile devices. The system does not require any location tracking modules, external hardware attachments, and/or optical fiducial markers for localizing a user’s position. Rather, the user’s location and orientation are purely derived by comparing images from the user’s mobile device to a 3D point cloud model generated from a set of pre-collected site photographs. Results The experimental results show that 1) the underlying 3D reconstruction module of the system generates complete 3D point cloud models of target scene, and is up to 35 times faster than other state-of-the-art Structure-from-Motion (SfM) algorithms, 2) the localization time takes at most few seconds in actual construction site. Conclusion The localization speed and empirical accuracy of the system provides the ability to use the system on real-world construction sites. Using an actual construction case study, the perceived benefits and limitations of the proposed method for on-site context-aware applications are discussed in detail.
60 Gbit/s WDM (20 Gbit/s x 3 unequally-spaced channels) soliton transmission over 10, 000 km (1996)

Soliton puise transmission has great potential for use in realizing a high speed OTDM system of more than 10 Gbit/s [1]. A soliton-based transmission at 20 Gbit/s over 8,1 00 km has been successfully achieved by incorporating fibers with both anomalous and normal GVD as this reduces the average GVD [2]. This technique is based on the principle of the dispersion-allocated soliton which enables us to construct soliton systems using already installed optical fibers [3] [4]. Bergano et al. reported a 5 Gbit/s ×20 channel NRZ pulse transmission over 9100 km [5]. If high speed WDM soliton transmission can be realized, it will be very useful for a future transoceanic system. WDM soliton transmission has recently been reported by using a sliding filter method ( 10 Gbit/s×8 channels) [6] and a synchronous modulation method (10 Gbit/s×4 channels) [7]. When the in-line modulation method is used, it is highly advantageous to increase the bit rate as it is similar to laser mode-locking at an ultrahigh repetition rate.
Hierarchical policy design for sample-efficient learning of robot table tennis through self-play (2019)

Training robots with physical bodies requires developing new methods and action representations that allow the learning agents to explore the space of policies efficiently. This work studies sample-efficient learning of complex policies in the context of robot table tennis. It incorporates learning into a hierarchical control framework using a model-free strategy layer (which requires complex reasoning about opponents that is difficult to do in a model-based way), model-based prediction of external objects (which are difficult to control directly with analytic control methods, but governed by learnable and relatively simple laws of physics), and analytic controllers for the robot itself. Human demonstrations are used to train dynamics models, which together with the analytic controller allow any robot that is physically capable to play table tennis without training episodes. Using only about 7000 demonstrated trajectories, a striking policy can hit ball targets with about 20 cm error. Self-play is used to train cooperative and adversarial strategies on top of model-based striking skills trained from human demonstrations. After only about 24000 strikes in self-play the agent learns to best exploit the human dynamics models for longer cooperative games. Further experiments demonstrate that more flexible variants of the policy can discover new strikes not demonstrated by humans and achieve higher performance at the expense of lower sample-efficiency. Experiments are carried out in a virtual reality environment using sensory observations that are obtainable in the real world. The high sample-efficiency demonstrated in the evaluations show that the proposed method is suitable for learning directly on physical robots without transfer of models or policies from simulation.
Highly selective synthesis of ethene from methanol on a novel nickel–silicoaluminophosphate catalyst (1990)

A novel Ni–silicoaluminophosphate catalyst synthesized by rapid crystallization exhibited prominently high selective synthesis of ethene from methanol under total conversion conditions and temperatures around 450 °C.
Robust Multivariable Control Using H ∞ Methods: Analysis, Design and Industrial Applications (1993)

The purpose of this paper is to introduce the reader to multivariable frequency domain methods including H ∞-design. These methods provide a direct generalization of the classical loop-shaping methods used for SISO systems. We also aim to provide a basic understanding of how robustness problems arise, and what analysis and design tools are available to identify and to avoid them. As an introduction to the robustness problems in multivariable systems we discuss the control of a distillation column. Because of strong interactions in the plant, a decoupling control strategy is extremely sensitive to input gain uncertainty (caused by actuator uncertainty). These interactions are analyzed using singular value decomposition (SVD) and relative gain array (RGA) methods. We then discuss possible sources of model uncertainty, and look at the traditional methods for obtaining robust designs, such as gain margin, phase margin and maximum peak criterions (M-circles). However, these measures are difficult to generalize to multivariable systems. In such cases a more detailed modelling of the uncertainty in terms of norm-bounded perturbations (Δ’s) is used. The frequency-domain is particularly well suited for representing non-parametric (unstructured) uncertainty. To test for robust stability and performance in the presence of model uncertainty, the structured singular value, μ, provides a powerful tool. The latter part of the paper is concerned with design and in particular multivariable loop shaping of singular values of appropriately specified transfer functions. One and two degrees of freedom controllers are considered, and the paper ends with a case study on advanced control of high performance helicopters.
Production of lithium oxide by decompostion lithium carbonate in the flow of a heat carrier (2009)

Decomposition of lithium carbonate with formation of lithium oxide in the flow of a high-temperature heat carrier studied. Atmospheric-pressure air was used as the heat transfer medium. The results of measurements show that the proposed method for producing lithium oxide is promising. In experiments, the lithium carbonate conversion into lithium oxide exceeds 70% perpass. A physical model for the process of lithium carbonate dissociation at high temperatures is considered.

Bloat investigations (1955)

An account is given of experimental work carried out at Jealott's Hill on bloat. Bloat was produced in dairy cows and sheep by dosing with lucerne juice. Sheep proved convenient test animals and were used in most of the tests described. Parenteral and intravenous administration of the flavone quercetin, which inhibits the activity of smooth muscle, did not cause bloat even in the presence of cyanide. It is unlikely that flavones are concerned in bloat. Fractionation of bloat-provoking lucerne juice showed that activity was retained after ( a ) precipitation of chloroplastic material, and ( b ) passage of clear juice through an anion or cation exchange resin. This suggests that the bloat-provoking factor is non-ionic and not adsorbed on resins—properties shown by saponinis. Dosing sheep with lucerne saponins, four other saponins, egg albumin and a synthetic foaming compound failed to produce bloat. Two household detergents and a number of surface-active agents did not relieve bloat, but foam-breaking compounds were very effective. A synthetic inorganic saliva and cow's saliva did not prevent bloat in sheep and from the single test made with cow's saliva it is not possible to say if it increased the severity of bloat. It is concluded that the formation of a stable foam is a major factor in lucerne bloat and that food constituents, other than saponins, and the physical condition of the rumen ingesta probably influence the stability of the foam.
Silicon recess minimization during gate patterning using synchronous plasma pulsing (2012)

With the emergence of new semiconductor devices and architectures, there is a real need to limit plasma induced damage. This study clearly demonstrates the capability of pulsed plasma technology to minimize plasma induced silicon oxidation that leads to the silicon recess phenomenon during polysilicon gate patterning. Indeed, the authors show that by pulsing optimized continuous wave overetch plasma conditions using HBr/He/O2 plasmas, the silicon recess is reduced from 0.6 to 0.2 nm, while the gate profiles are maintained anisotropic. Synchronous pulsed plasmas open new paths to pattern complex stacks of ultrathin materials without surface damage.
A nuclear localization signal and the C-terminal omega sequence in the Agrobacterium tumefaciens VirD2 endonuclease are important for tumor formation. (1992)

The T-DNA portion of the Agrobacterium tumefaciens tumor-inducing (Ti) plasmid integrates into plant nuclear DNA. Direct repeats define the T-DNA ends; transfer begins when the VirD2 endonuclease produces a site-specific nick in the right-hand border repeat and attaches to the 5' end of the nicked strand. Subsequent events generate linear single-stranded VirD2-bound DNA molecules that include the entire T-DNA (T-strands). VirD2 protein contains a nuclear localization signal (NLS) near the C terminus and may direct bound T-strands to plant nuclei. We constructed mutations in virD2 and showed that the NLS was important for tumorigenesis, although T-strand production occurred normally in its absence. A tobacco etch virus NLS, substituted for the VirD2 NLS, restored tumor-inducing activity. Amino acids (the omega sequence) at the C terminus of VirD2, outside the NLS and the endonuclease domain, contributed significantly to tumorigenesis, suggesting that VirD2 may serve a third important function in T-DNA transfer.
