Inositol 1,4,5 trisphosphate releases calcium from specialized sites within Limulus photoreceptors (1987)

We have investigated the subcellular distribution and identity of inositol trisphosphate (InsP3)-sensitive calcium stores in living Limulus ventral photoreceptor cells, where light and InsP3 are known to raise intracellular calcium. We injected ventral photoreceptor cells with the photoprotein aequorin and viewed its luminescence with an image intensifier. InsP3 only elicited detectable aequorin luminescence when injected into the light-sensitive rhabdomeral (R)-lobe where aequorin luminescence induced by light was also confined. Calcium stores released by light and InsP3 are therefore localized to the R-lobe. Within the R-lobe, InsP3-induced aequorin luminescence was further confined around the injection site, due to rapid dilution and/or degradation of injected InsP3. Prominent cisternae of smooth endoplasmic reticulum are uniquely localized within the cell beneath the microvillar surface of the R-lobe (Calman, B., and S. Chamberlain, 1982, J. Gen. Physiol., 80:839-862). These cisternae are the probable site of InsP3 action.
Gadolinium Nanoparticle Based Switchable Mirrors: Quenching of Hydrogenation–Dehydrogenation Hysteresis (2007)

A continuous and reversible 'structural, optical, and electronic' transition between the reflecting metallic dihydride and transparent semiconducting trihydride states observed in rare earth metals on hydrogenation make these materials and their hydrides suitable for switchable mirror, sensing, and other technological applications. Recently Pd capped Gd nanoparticle based 'new generation' switchable mirrors have been fabricated with extended color neutrality, better optical contrast, and faster kinetics in comparison to the polycrystalline, epitaxial, alloy, and multilayer films. The present report aims at investigating the effect of nanoparticle nature on the hydrogenation-dehydrogenation hysteresis in switchable mirrors by carrying out in situ measurement of optical transmittance and electrode potentials during electrochemical hydrogen loading-deloading of Gd nanoparticle samples. Interestingly, Gd nanoparticle samples were observed to exhibit quenched hysteresis. The quenching of hysteresis in hydrogen-induced properties has been attributed to the absence of structural transition upon hydrogenation, reduction in topographical interlocking of the grains and elimination of lateral clamping of the slack nanoparticle layer to the substrate.
Panorama-Based Multilane Recognition for Advanced Navigation Map Generation (2015)

Precise navigation map is crucial in many fields. This paper proposes a panorama based method to detect and recognize lane markings and traffic signs on the road surface. Firstly, to deal with the limited field of view and the occlusion problem, this paper designs a vision-based sensing system which consists of a surround view system and a panoramic system. Secondly, in order to detect and identify traffic signs on the road surface, sliding window based detection method is proposed. Template matching method and SVM (Support Vector Machine) are used to recognize the traffic signs. Thirdly, to avoid the occlusion problem, this paper utilities vision based ego-motion estimation to detect and remove other vehicles. As surround view images contain less dynamic information and gray scales, improved ICP (Iterative Closest Point) algorithm is introduced to ensure that the ego-motion parameters are consequently obtained. For panoramic images, optical flow algorithm is used. The results from the surround view system help to filter the optical flow and optimize the ego-motion parameters; other vehicles are detected by the optical flow feature. Experimental results show that it can handle different kinds of lane markings and traffic signs well.
Complex support vector regression (2012)

We present a support vector regression (SVR) rationale for treating complex data, exploiting the notions of widely linear estimation and pure complex kernels. To compute the Lagrangian and derive the dual problem, we employ the recently presented Wirtinger's calculus on complex RKHS. We prove that this approach is equivalent with solving two real SVR problems exploiting a specific real kernel, which it is induced by the chosen complex kernel.
Laboratory Projects in Tactile Aids to Lipreading (1984)

Four studies are reported on the design of tactile aids to lipreading conducted at Central Institute for the Deaf, St. Louis. A speech feature aid represented resonance, envelope, and source characteristics of speech on three vibrators at the fingertips. Artificially-deafened and congenitally deaf adults lipreading with the aid obtained an average of 40% gain over lipreading alone on syllable identification tests, but minimal gain for untrained words. In a series of three other studies, the quality of tactile sensation was developed as a cue to spectral information, presented in a temporal code based on the overall time-intensity waveform of speech. Electrical and vibratory stimulation on the hand and torso were evaluated by artificially-deafened adults using the tracking technique with connected speech. Short-term training yielded variable increments over unaided lipreading scores and lipreading with a simple vibrator aid. Neither the feature nor the spectral code was superior in aiding lipreading. The displays that produced quality changes seemed more efficient for training than the spatial display. Results were affected also by content and method of training and initial lipreading proficiency.
Soccer Teams Behaviors: Analysis of the Team's Distribution in Function to Ball Possession (2013)

Innovative tools to soccer analysis are the main concern of the sport performance analysts. Considering team players occupation as one of the fundamental characteristics of soccer success, is too important generate new systems to interpret the post-match reality. These systems must be easy for the coach's applications. Thus, this study proposes an easy tool to understand the team’s collective behaviour in function to their ball possession status. Through the histograms of all team players will be possible understand the most occupied areas by each team, trying understand possible tendencies in the moments with and without ball possession. Were analyzed two teams during an official soccer match, collecting their positions at each instant. Using this tracking was possible perform two heat maps by each team, representing the moments with and without ball possession. Through this method was possible analyze different collective behaviors and explain how could coaches interpret outcomes.
Prediction of postprandial blood glucose under intra-patient variability and uncertainty and its use in the design of insulin dosing strategies for type 1 diabetic patients (2011)

In this thesis I propose a novel method to estimate the dose and injection-to-meal time for low-risk intensive insulin therapy. This dosage-aid system uses an optimization algorithm to determine the insulin dose and injection-to-meal time that minimizes the risk of postprandial hyper- and hypoglycaemia in type 1 diabetic patients. To this end, the algorithm applies a methodology that quantifies the risk of experiencing different grades of hypo- or hyperglycaemia in the postprandial state induced by insulin therapy according to an individual patient’s parameters. This methodology is based on modal interval analysis (MIA). Applying MIA, the postprandial glucose level is predicted with consideration of intra-patient variability and other sources of uncertainty. A worst-case approach is then used to calculate the risk index. In this way, a safer prediction of possible hyper- and hypoglycaemic episodes induced by the insulin therapy tested can be calculated in terms of these uncertainties.
Epoxidation of styrene–butadiene block polymers. I (1979)

A styrene–butadiene–styrene (20–60–20) linear block polymer was epoxidized in toluene and cyclohexane solutions with peroxyformic acid generated in situ. The epoxidized polymer, containing about 8% oxygen, exhibits greatly improved resistance to ASTM oils. It can be readily compounded with carbon black, and the unvulcanized stock is found to be comparable to vulcanized polychloroprene and nitrile rubber in tensile strength and resistance to ASTM oils and certain chemicals.

A class of codes derived from algebraic plane curves is constructed. The concepts and results from algebraic geometry that were used are explained in detail; no further knowledge of algebraic geometry is needed. Parameters, generator and parity-check matrices are given. The main result is a decoding algorithm which turns out to be a generalization of the Peterson algorithm for decoding BCH decoder codes.< <ETX xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">></ETX>
Characterization of Rice Anthranilate Synthase α-Subunit Genes<i>OASA1</i> and <i>OASA2</i>. Tryptophan Accumulation in Transgenic Rice Expressing a Feedback-Insensitive Mutant of OASA1 (2001)

Anthranilate synthase (AS) is a key enzyme in the synthesis of tryptophan (Trp), indole-3-acetic acid, and indole alkaloids. Two genes, OASA1 and OASA2, encoding AS alpha-subunits were isolated from a monocotyledonous plant, rice (Oryza sativa cv Nipponbare), and were characterized. A phylogenetic tree of AS alpha-subunits from various species revealed a close evolutionary relationship among OASA1 and Arabidopsis ASA2, Ruta graveolens AS alpha 2, and tobacco ASA2, whereas OASA2, Arabidopsis ASA1, and R. graveolens AS alpha 1 were more distantly related. OASA1 is expressed in all tissues tested, but the amount of its mRNA was greater in panicles than in leaves and roots. The abundance of OASA2 transcripts is similar among tissues and greater than that of OASA1 transcripts; furthermore, OASA2 expression was induced by a chitin heptamer, a potent elicitor, suggesting that OASA2 participates in secondary metabolism. Expression of wild-type OASA1 or OASA2 transgenes did not affect the Trp content of rice calli or plants. However, transformed calli and plants expressing a mutated OASA1 gene, OASA1(D323N), that encodes a protein in which aspartate-323 is replaced with asparagine manifested up to 180- and 35-fold increases, respectively, in Trp accumulation. These transgenic calli and plants were resistant to 300 microM 5-methyl-Trp, and AS activity of the calli showed a markedly reduced sensitivity to Trp. These results show that OASA1 is important in the regulation of free Trp concentration, and that mutation of OASA1 to render the encoded protein insensitive to feedback inhibition results in accumulation of Trp at high levels. The OASA1(D323N) transgene may prove useful for the generation of crops with an increased Trp content.
Mädchen und Jungen in Aktion. Ethnographische Ansätze in der schulischen peer culture Forschung (1999)

Several approaches aimed at detecting and cloning interactive transcriptional regulatory proteins have been presented. All of the techniques can effectively identify specific interactions between two transcription proteins. However, interaction cloning and the two hybrid system have the added advantage of yielding a cDNA expression clone directly. The other methods, EMSA-mediated cloning, co-immunoprecipitation, oligonucleotide/PCR-facilitated cloning, Southwestern, and Farwestern, require additional manipulations to obtain a cDNA clone. Clearly, the interactive cloning system of choice will depend on the proteins under investigation.
Recombinant adeno-associated virus-mediated microRNA delivery into the postnatal mouse brain reveals a role for miR-134 in dendritogenesis in vivo (2009)

Recent studies using primary neuronal cultures have revealed important roles of the microRNA pathway in the regulation of neuronal development and morphology. For example, miR-134 is involved in dendritogenesis and spine development in hippocampal neurons by regulating local mRNA translation in dendrites. The in vivo roles of microRNAs in these processes are still uninvestigated, partly due to the lack of tools enabling stable in vivo delivery of microRNAs or microRNA inhibitors into neurons of the mammalian brain. Here we describe the construction and validation of a vector-based tool for stable delivery of microRNAs in vivo by use of recombinant adeno-associated virus (rAAV). rAAV-mediated overexpression of miR-134 in neurons of the postnatal mouse brain provided evidence for a negative role of miR-134 in dendritic arborization of cortical layer V pyramidal neurons in vivo, thereby confirming previous findings obtained with cultured neurons. Our system provides researchers with a unique tool to study the role of any candidate microRNA in vivo and can easily be adapted to microRNA loss-of-function studies. This platform should therefore greatly facilitate investigations on the role of microRNAs in synapse development, plasticity and behavior in vivo.
Nonrigid Registration of Prostate Diffusion-Weighted MRI (2017)

Motion and deformation are common in prostate diffusion-weighted magnetic resonance imaging (DWI) during acquisition. These misalignments lead to errors in estimating an apparent diffusion coefficient (ADC) map fitted with DWI. To address this problem, we propose an image registration algorithm to align the prostate DWI and improve ADC map. First, we apply affine transformation to DWI to correct intraslice motions. Then, nonrigid registration based on free-form deformation (FFD) is used to compensate for intraimage deformations. To evaluate the influence of the proposed algorithm on ADC values, we perform statistical experiments in three schemes: no processing of the DWI, with the affine transform approach, and with FFD. The experimental results show that our proposed algorithm can correct the misalignment of prostate DWI and decrease the artifacts of ROI in the ADC maps. These ADC maps thus obtain sharper contours of lesions, which are helpful for improving the diagnosis and clinical staging of prostate cancer.
Review of Phytophagous Pentatomids (Hemiptera: Pentatomidae) Associated with Soybean in the Americas (1985)

Published research on stink bugs (Pentatomidae) associated with soybean in the Americas is compiled and reviewed. Emphasis is placed on Nezara viridula (L.), Acrosternum hilare (Say), Piezodorus guildinii (Westwood), and Euschistus heros (F.). Nymphs and adults feed via stylet insertion primarily in seeds, reducing seed yield and quality and sometimes causing prolonged leaf retention and development of abnormal leaflets and pods. Colonization of soybean by pentatomids typically starts during pre-blooming and peaks by late pod-filling stage. As plants senesce, movement to alternate hosts occurs. Economic thresholds in soybean differ throughout the Americas and normally control measures are required. Important natural enemies of phytophagous pentatomids include the hymenopteran egg parasites Trissolcus basalis (Wollaston) and Telenomus mormideae Lima, and the tachinid adult parasites Trichopoda pennipes (F.) and Eutrichopodopsis nitens Blanchard. Cultural and chemical control strategies and host plant resistance to stink bugs are discussed. Opportunities for future research within the philosophy and methodology of Integrated Pest Management (IPM) are suggested.
Environmental, morphological and physiological factors analyzes for optimization of potato (&lt;i&gt;Solanum tuberosum&lt;/i&gt; L.) microtuber &lt;i&gt;in vitro&lt;/i&gt; germination (2013)

The microtuber is considered one of the most effective means of spreading basic materials, as well as transporting and preserving potato germplasm varieties. To define the optimal conditions for the potato microtuber in vitro germination of Aida, Atlas and Odessa varieties, the effects of temperature, physiological age and grade (size) were evaluated. The study conducted at three different temperature levels has demonstrated that the most favorable temperature for microtuber germination at a higher and faster germination rate was 25℃, regardless of the variety. In addition, microtubers of large caliber, greater than 4 mm, germinate more quickly, with a higher germination rate, than smaller size ones (less than 4 mm) for all genotypes. For Atlas, Aida and Odessa varieties, a germination rate equal to 86.66%, 70% and 70% respectively, was obtained for microtubers with a caliber superior to 4 mm. Physiological age influences microtuber germination. The mean length of sprouts, reached after a 7 week incubation period, was more marked at “multiple sprout” and “branched sprout” stages than at a “monosprout” stage. The average length was 2.35 cm, 2.48 cm and 1.5 cm, respectively. Thus, it is necessary to plant microtubers at a “multiple sprout” stage to optimize their yield in plants and minitubers.
Frame adaptive ROI for photoplethysmography signal extraction from fingertip video captured by smartphone (2015)

Photoplethysmography (PPG) has been widely used in clinical applications for monitoring vital signs especially heart rate by pulse oximeter. Recent researches have demonstrated the possibility of using fingertip video based PPG approach to estimate heart rate by smartphones. However, due to the variation of camera sensor characteristics in difference smartphones, the conventional fixed region-of-interest (ROI) for PPG signal extraction technique is not reliable. In this paper, a novel frame adaptive ROI method is proposed to detour the color saturation or cut-off distortion in the fingertip video capturing process for improving the reliability due to variation and limited dynamic range of the camera sensors in different smartphone models. Experimental results demonstrate that the proposed method can produce good pulsatile waveform and achieve high heart rate estimation accuracy using different smartphone models as compared with a FDA (U.S. Food and Drug Administration) approved commercial pulse oximeter.
Highly Efficient Cyanoimidation of Aldehydes (2009)

Cyanoimidation of aldehydes using cyanamide as a nitrogen source and using NBS as an oxidant was achieved in high yields without the addition of a catalyst. The method has several advantages, including mild conditions, simple workflow, and inexpensive reagents. The reaction proceeds in a one-pot manner, giving rise to the formation of intermolecular C-N and C-O bonds. Subsequently, the substituted N-cyanobenimidate products may also undergo a cyclization reaction to give l,2,4-triazole derivatives in high yields.
ARDE: a novel framework to define workflow participants (2005)

The organizational structures-based workflow participant definition, which appoints activity executors according to user's role, department or ID, is widely used in commercial workflow management systems presently. This approach lacks of flexible mechanisms for complex participants assignment. This paper describes a novel approach (ARDE) to define workflow participants. ARDE defines participant from four facets, namely assignment, rule, duration and exception. Assignment uses an SQL-like language to define the qualification that activity participants must meet. Rule expresses a regulation to choose user(s) from all of qualified participants to undertake the task at runtime. The regulation considers the use's context, including workload, online and vacancy, etc. Duration is the interval during which the task starts and completes. Exception represents the handling strategy when a task cannot be finished in the planned duration. In order to enforce the expression capacity, an organizational meta-model, several built-in functions and an entity outdata are introduced in this article
Frequency ratios of Sr, Yb, and Hg based optical lattice clocks and their applications (2015)

This article describes the recent progress of optical lattice clocks with neutral strontium ( 87 Sr), ytterbium ( 171 Yb) and mercury ( 199 Hg) atoms. In particular, we present frequency comparison between the clocks locally via an optical frequency comb and between two Sr clocks at remote sites using a phase-stabilized fibre link. We first review cryogenic Sr optical lattice clocks that reduce the room-temperature blackbody radiation shift by two orders of magnitude and serve as a reference in the following clock comparisons. Similar physical properties of Sr and Yb atoms, such as transition wavelengths and vapour pressure, have allowed our development of a compatible clock for both species. A cryogenic Yb clock is evaluated by referencing a Sr clock. We also report on an Hg clock, which shows one order of magnitude less sensitivity to blackbody radiation, while its large nuclear charge makes the clock sensitive to the variation of fine-structure constant. Connecting all three types of clocks by an optical frequency comb, the ratios of the clock frequencies are determined with uncertainties smaller than possible through absolute frequency measurements. Finally, we describe a synchronous frequency comparison between two Sr-based remote clocks over a distance of 15 km between RIKEN and the University of Tokyo, as a step towards relativistic geodesy.
Quality of experience measurement for light field 3D displays on multilayer LCDs (2016)

Abstract Multi‐layer light field displays (MLLFDs) are a promising computational display type that can not only display hologram‐like 3D content but will also be well compatible with normal 2D applications. However, the quality of experience measurement for MLLFDs is always an important yet challenging issue. Despite existing research works on MLLFDs, most of them only provide quality of experience results with qualitative evaluation, for example, software simulation of a few 3D images/videos, rather than rigorous quantitative evaluation. This work targets at building a unified software and hardware measurement platform for different MLLFD methods, and comprehensively measuring both objective and subjective performance based on virtual object models. To the best of our knowledge, it is the first time that such performance has been measured for MLLFDs. In addition, to use the existing disclosed virtual object sequences, this paper further proposes three customized virtual models, which are the USAF‐E model, the view angle model, and the concave/convex object model for accurate measurement of spatial resolution, viewing angle, and depth resolution. A toolbox for MLLFD measurement with proposed models is also released in this paper. The experimental results demonstrate that our proposed measurement method, models, and toolbox can well measure MLLFDs in different configurations.
Continuous Intrathecal Infusion of Hydromorphone: Safety in the Sheep Model and Clinical Implications (2004)

Hydromorphone was not associated with inflammatory mass formation in the sheep model. Further studies are necessary to determine whether hydromorphone is a safer alternative to morphine for continuous intrathecal infusion for the treatment of chronic pain.
Isotropic yielding in an artificially cemented soil cured under stress (2003)

The work simulates, in the laboratory, the formation of a cemented sedimentary deposit in which cement bonding occurs after burial and under geostatic stresses. Isotropic compression tests were carried out on artificially cemented specimens made with variable cement contents. After consolidating the samples to the uncemented normal compression line, the specimens were allowed to cure for 48 h before testing. The curing confining stresses ranged from 50 to 2000 kPa, and were intended to represent soil elements at different depths in the fictitious sedimentary deposit when the cementing occurred. The contribution of the cement bonds to soil compression and the changes in the isotropic yield stress as a function of void ratio and cement content were analysed. The results showed the importance of the void ratio during the formation of cement bonds and also of the degree of cementation for the compressive behaviour of the cemented soil, and demonstrated that the variation in yield stress with void ratio and cement content is dependent on the curing stress and independent of the stress history.
