CAROTENOID CLEAVAGE DIOXYGENASE4Is a Negative Regulator of β-Carotene Content inArabidopsisSeeds (2013)

Experimental approaches targeting carotenoid biosynthetic enzymes have successfully increased the seed β-carotene content of crops. However, linkage analysis of seed carotenoids in Arabidopsis thaliana recombinant inbred populations showed that only 21% of quantitative trait loci, including those for β-carotene, encode carotenoid biosynthetic enzymes in their intervals. Thus, numerous loci remain uncharacterized and underutilized in biofortification approaches. Linkage mapping and genome-wide association studies of Arabidopsis seed carotenoids identified CAROTENOID cleavage dioxygenase4 (CCD4) as a major negative regulator of seed carotenoid content, especially β-carotene. Loss of CCD4 function did not affect carotenoid homeostasis during seed development but greatly reduced carotenoid degradation during seed desiccation, increasing β-carotene content 8.4-fold relative to the wild type. Allelic complementation of a ccd4 null mutant demonstrated that single-nucleotide polymorphisms and insertions and deletions at the locus affect dry seed carotenoid content, due at least partly to differences in CCD4 expression. CCD4 also plays a major role in carotenoid turnover during dark-induced leaf senescence, with β-carotene accumulation again most strongly affected in the ccd4 mutant. These results demonstrate that CCD4 plays a major role in β-carotene degradation in drying seeds and senescing leaves and suggest that CCD4 orthologs would be promising targets for stabilizing and increasing the level of provitamin A carotenoids in seeds of major food crops.
Tableros de fibras de la madera de "tornillo" (Cedrelinga cateniformis Ducke) (2003)

"Fiberboards were manufactured using the pulp of two raw materials: sawdust and chips of a tropical wood, "tornillo" (Cedrelinga cateniformis Ducke). The pulp was obtained by means of the cold soda chemi-mechanical process with a yield of 78%. The average dimensions of the fiberboards were 0.40 m x 0.40 m by 5 mm in thickness using 1.5% colophony and 2% alum. The fibrous mantle (MAT) was subjected to 5 kg/cm² of room temperature pressing for 2 min, followed by a hot pressing in a diagram of 110 kg/cm², 40 kg/cm² and 80 kg/cm² for 4, 15 and 4 min, respectively. The density of fiberboards made from sawdust pulp was 958 kg/m³ and 967 kg/m³ for fiberboards made from pulp chips and the water absorption values were 69% and 60% for both kinds of fiberboards, respectively. The Modulus of Rupture (MOR) was 107 kg/cm² and 242 kg/cm², respectively. Statistically, the values of the fiberboard properties displayed a great variability and there were significant differences between both types."

Factors influencing on intention to intake fruit: moderating effect of fruit intake habit (2014)

Purpose: The purpose of this study is to identify factors affecting fruit consumption behavior by application of the Theory of Planned Behavior. In addition, this study examined the moderating effect of a fruit eating habit. Methods: A total of 734 consumers who have ever purchased fruit participated in this study. Results: Results of this study showed that attitudes toward fruit intake, social norms, and perceived behavioral control had significant impacts on the level of fruit intake. Fruit eating habit that showed high correlation with eating behavior was also included in the model identifying factors having an influence on fruit intake. Attitudes toward fruit intake, social norms, and perceived behavioral control had a positive influence on intention to intake fruit. Fruit eating habits played a moderating role in the relationships between intention to intake fruit and real fruit intake. Conclusion: Increasing positive attitudes toward fruit intake, social norms, and perceived behavioral control would be helpful in increasing the amount of fruit intake.
Abstract P081: Increased Hepatic Fat Is Associated With A More Atherogenic Lipoprotein Profile In Adolescents (2014)

Introduction: Nonalcoholic fatty liver disease (NAFLD) has emerged as the most common liver disease in pediatrics, and it has been estimated to affect more than one third of obese adolescents in the United States. In adolescents with NAFLD, traditional markers of increased cardiovascular risk are commonly reported including elevated triglycerides and reduced HDL-cholesterol levels. Despite the fact that lipoproteins are critically involved in atherogenesis and cardiovascular disease, the independent impact of NAFLD on size and particle concentration of major lipoproteins remains less well described and studies in pediatric population are particularly scarce. Hypothesis: In the current study, we assessed the hypothesis that in adolescents, high hepatic fat would have a strong association with an atherogenic pattern of lipoprotein particle size and concentration. Methods: Hispanic-American overweight and obese adolescents (n=50) were recruited from pediatric clinics at Emory Children’s Center and from nearby community centers through flyers and presentations at community events. We evaluated their hepatic fat content by magnetic resonance spectroscopy and measured lipoprotein particles by nuclear magnetic resonance (Liposcience, Raleigh, NC). Results: Using the 5% hepatic fat to stratify subjects with low (n=13) and high hepatic fat (n=37), adolescents with high hepatic fat have undesirable lipoprotein subclass profiles, including larger VLDL particle size (51.2 ± 1.36 vs. 44.8 ± 1.31 nm, p=0.010), more large VLDL particle numbers (5.75 ± 0.93 vs. 1.32 ± 0.18 nmol/L, p&lt;0.001), and fewer large HDL particles (4.15 ± 0.33 vs. 5.69 ± 0.67 μmol/L, p=0.033). Strong correlations were found between hepatic fat and the number of large VLDL particles (r=0.521, p&lt;0.001), VLDL particle size (r=0.439, p=0.002), and small, dense LDL particle numbers (r=0.291, p=0.040). Conclusions: The amount of hepatic fat is closely related to the presence of large VLDL particle and small dense LDL, two important predictors of CVD. This suggests that hepatic fat and the associated dyslipidemia have interrelated mechanisms. Further studies with histologic assessment of NAFLD (liver biopsies) will be needed to confirm our findings and to explore causation.
Optimizing TCP forwarder performance (2000)

A TCP forwarder is a network node that establishes and forwards data between a pair of TCP connections. An example of a TCP forwarder is a firewall that places a proxy between a TCP connection to an external host and a TCP connection to an internal host, controlling access to a resource on the internal host. Once the proxy approves the access, it simply forwards data from one connection to the other. We use the term TCP forwarding to describe indirect TCP communication via a proxy in general. This paper characterizes the behavior of TCP forwarding, and illustrates the role TCP forwarding plays in common network services like firewalls and HTTP proxies. We then introduce an optimization technique, called connection splicing, that can be applied to a TCP forwarder, and report the results of a performance study designed to evaluate its impact. Connection splicing improves TCP forwarding performance by a factor of two to four, making it competitive with IP router performance on the same hardware.
High performance, diode-pumped, Q-switched Er:Yb:glass laser with FTIR shutter (2002)

Summary form only. Q-switched erbium-laser pulse energies at /spl lambda/=1.54 /spl mu/m have generally been severely limited due to low damage threshold of the electro-optic modulator materials presently available at this wavelength and due to the polarization sensitivity of the usual electrooptic shutters. Here, by employing the frustrated total internal reflection (FTIR) Q-switching scheme in a diode-pumped Er:Yb:glass laser, we demonstrate that record-high nanosecond-pulse energies can be obtained from such a compact system.
Vertically-integrated package (2003)

A packaging concept has been developed to optimize system integration for electronic designs that contain VLSI semiconductors requiring a large quantity of passive-component support. The concept was realized by designing an inverted-cavity, leadless ceramic chip carrier that uses two surfaces for component attachment. Semiconductors and similar devices that require environmental protection are mounted and hermetically sealed in the lower, recessed cavity. Metallized vias pass vertically from the cavity base through multiple interconnect layers to bonding pads on the chip carrier's top surface for mounting resistor and capacitor chips. By combining active and passive components within the same structure by using two surfaces, packaging density is greatly increased over that of comparable chip and wire hybrid designs. Furthermore, this concept provides for full burn-in and electrical characterization of active and passive components prior to substrate assembly.< <ETX xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">&gt;</ETX>
Beta-band activity in auditory pathways reflects speech localization and recognition in bilateral cochlear implant users (2013)

In normal-hearing listeners, localization of auditory speech involves stimulus processing in the postero-dorsal pathway of the auditory system. In quiet environments, bilateral cochlear implant (CI) users show high speech recognition performance, but localization of auditory speech is poor, especially when discriminating stimuli from the same hemifield. Whether this difficulty relates to the inability of the auditory system to translate binaural electrical cues into neural signals, or to a functional reorganization of auditory cortical pathways following long periods of binaural deprivation is unknown. In this electroencephalography study, we examined the processing of auditory syllables in postlingually deaf adults with bilateral CIs and in normal-hearing adults. Participants were instructed to either recognize ("recognition" task) or localize ("localization" task) the syllables. The analysis focused on event-related potentials and oscillatory brain responses. N1 amplitudes in CI users were larger in the localization compared with recognition task, suggesting an enhanced stimulus processing effort in the localization task. Linear beamforming of oscillatory activity in CI users revealed stronger suppression of beta-band activity after 200 ms in the postero-dorsal auditory pathway for the localization compared with the recognition task. In normal-hearing adults, effects for longer latency event-related potentials were found, but no effects were observed for N1 amplitudes or beta-band responses. Our study suggests that difficulties in speech localization in bilateral CI users are not reflected in a functional reorganization of cortical auditory pathways. New signal processing strategies of cochlear devices preserving unambiguous binaural cues may improve auditory localization performance in bilateral CI users.
Metabolic Engineering in the -omics Era: Elucidating and Modulating Regulatory Networks (2005)

The importance of regulatory control in metabolic processes is widely acknowledged, and several enquiries (both local and global) are being made in understanding regulation at various levels of the metabolic hierarchy. The wealth of biological information has enabled identifying the individual components (genes, proteins, and metabolites) of a biological system, and we are now in a position to understand the interactions between these components. Since phenotype is the net result of these interactions, it is immensely important to elucidate them not only for an integrated understanding of physiology, but also for practical applications of using biological systems as cell factories. We present some of the recent "-omics" approaches that have expanded our understanding of regulation at the gene, protein, and metabolite level, followed by analysis of the impact of this progress on the advancement of metabolic engineering. Although this review is by no means exhaustive, we attempt to convey our ideology that combining global information from various levels of metabolic hierarchy is absolutely essential in understanding and subsequently predicting the relationship between changes in gene expression and the resulting phenotype. The ultimate aim of this review is to provide metabolic engineers with an overview of recent advances in complementary aspects of regulation at the gene, protein, and metabolite level and those involved in fundamental research with potential hurdles in the path to implementing their discoveries in practical applications.
A Modified JPDA (2006)

This paper presents a coupled, joint probabilistic data association (JPDA) algorithm for multi-target tracking using a modified version of the standard measurement-to-track assignment model. The mutually exclusive nature of standard JPDA association events precludes any measurement being associated with more than one target in a given event. This constraint is relaxed here to allow a measurement to be assigned to multiple targets. All other JPDA assumptions are retained (i.e., no measurement can be simultaneously associated with target and clutter, and each track can claim at most one measurement). The computational requirements of the resulting algorithm grow linearly with the number of tracks. The recursive estimators for the coupled track means and covariance are derived and presented
Synaptic pathology and therapeutic repair in adult retinoschisis mouse by AAV-RS1 transfer (2015)

Strategies aimed at invoking synaptic plasticity have therapeutic potential for several neurological conditions. The human retinal synaptic disease X-linked retinoschisis (XLRS) is characterized by impaired visual signal transmission through the retina and progressive visual acuity loss, and mice lacking retinoschisin (RS1) recapitulate human disease. Here, we demonstrate that restoration of RS1 via retina-specific delivery of adeno-associated virus type 8-RS1 (AAV8-RS1) vector rescues molecular pathology at the photoreceptor-depolarizing bipolar cell (photoreceptor-DBC) synapse and restores function in adult Rs1-KO animals. Initial development of the photoreceptor-DBC synapse was normal in the Rs1-KO retina; however, the metabotropic glutamate receptor 6/transient receptor potential melastatin subfamily M member 1-signaling (mGluR6/TRPM1-signaling) cascade was not properly maintained. Specifically, the TRPM1 channel and G proteins Gαo, Gβ5, and RGS11 were progressively lost from postsynaptic DBC dendritic tips, whereas the mGluR6 receptor and RGS7 maintained proper synaptic position. This postsynaptic disruption differed from other murine night-blindness models with an electronegative electroretinogram response, which is also characteristic of murine and human XLRS disease. Upon AAV8-RS1 gene transfer to the retina of adult XLRS mice, TRPM1 and the signaling molecules returned to their proper dendritic tip location, and the DBC resting membrane potential was restored. These findings provide insight into the molecular plasticity of a critical synapse in the visual system and demonstrate potential therapeutic avenues for some diseases involving synaptic pathology.
Overlay optimization for 1x node technology and beyond via rule based sparse sampling (2016)

We demonstrate a cost-effective automated rule based sparse sampling method that can detect the spatial variation of overlay errors as well as the overlay signature of the fields. Our technique satisfies the following three rules: (i) homogeneous distribution of ~200 samples across the wafer, (ii) equal number of samples in scan up and scan down condition and (iii) equal number of sampling on each overlay marks per field. When rule based samplings are implemented on the two products, the differences between the full wafer map sampling and the rule based sampling are within 3.5 nm overlay spec with residuals M+3&sigma; of 2.4 nm (x) and 2.43 nm (y) for Product A and 2.98 nm (x) and 3.32 nm (y) for Product B.
Total energy minimization through dynamic station-user connection in macro-relay network (2013)

In this paper, we investigate the energy efficiency problem in macro-relay network. Considering users with different locations and rate requirements, our objective is to serve all users with strict rate guarantee and meanwhile minimize the total energy consumption of the network. First, we formulate an integer optimization problem with the variables as stationuser connections. Then we analyze the complexity of the optimal brute-force search (BFS) method and propose a practical algorithm, i.e., serving station selection for energy minimization (SSSEM). The proposed SSSEM algorithm dynamically alters user's serving station according to both the radio frequency energy and the circuit energy, thus minimizing the total energy consumption of the network. Extensive simulations are conducted and the results show that, compared with existing schemes, the proposed SSSEM algorithm can significantly reduce the total energy consumption of the network, and meanwhile achieve the optimum of BFS.

Point Pattern Matching Algorithm for Planar Point Sets under Euclidean Transform (2012)

Point pattern matching is an important topic of computer vision and pattern recognition. In this paper, we propose a point pattern matching algorithm for two planar point sets under Euclidean transform. We view a point set as a complete graph, establish the relation between the point set and the complete graph, and solve the point pattern matching problem by finding congruent complete graphs. Experiments are conducted to show the effectiveness and robustness of the proposed algorithm.
Polarization properties and dispersion relations for spiral resonances of a dielectric rod (2005)

Dielectric microcavities based on cylindrical and deformed cylindrical shapes have been employed as resonators for microlasers. Such systems support spiral resonances with finite momentum along the cylinder axis. For such modes the boundary conditions do not separate, and simple TM and TE polarization states do not exist. We formulate a theory for the dispersion relations and polarization properties of such resonances for an infinite dielectric rod of arbitrary cross section and then solve for these quantities for the case of a circular cross section (cylinder). Useful analytic formulas are obtained using the eikonal (Einstein–Brillouin–Keller) method, which are shown to be excellent approximations to the exact results from the wave equation. The major finding is that the polarization of the radiation emitted into the far field is linear up to a polarization critical angle (PCA) at which it changes to elliptical. The PCA always lies between the Brewster’s and total-internal-reflection angles for the dielectric, as is shown by an analysis based on the Jones matrices of the spiraling rays.
Scene recognition with omnidirectional vision for topological map using lightweight adaptive descriptors (2009)

Mobile robots rely on their ability of scene recognition to build a topological map of the environment and perform location-related tasks.In this paper, we describe a novel lightweight scene recognition method using an adaptive descriptor which is based on color features and geometric information for omnidirectional vision.Our method enables the robot to add nodes to a topological map automatically and solve the localization problem of mobile robot in realtime.The descriptor of a scene is extracted in the YUV color space and its dimension is adaptive depending on the segmentation result of the panoramic image.Furthermore, the descriptor is invariant to rotation and slight changes of illumination.The robustness of the scene matching and recognition is tested through real experiments in a dynamic indoor environment.The experiment is carried out on a mobile robot equipped with an omnidirectional camera.In our tests, the average processing time is 30 ms for each frame including feature extraction, matching, and the adding of new nodes.
Transition Metal-Modified Zirconium Phosphate Electrocatalysts for the Oxygen Evolution Reaction (2017)

Zirconium phosphate (ZrP), an inorganic layered nanomaterial, is currently being investigated as a catalyst support for transition metal-based electrocatalysts for the oxygen evolution reaction (OER). Two metal-modified ZrP catalyst systems were synthesized: metal-intercalated ZrP and metal-adsorbed ZrP, each involving Fe(II), Fe(III), Co(II), and Ni(II) cations. Fourier transform infrared spectroscopy, X-ray powder diffraction, thermogravimetric analysis, and X-ray photoelectron spectroscopy were used to characterize the composite materials and confirm the incorporation of the metal cations either between the layers or on the surface of ZrP. Both types of metal-modified systems were examined for their catalytic activity for the OER in 0.1 M KOH solution. All metal-modified ZrP systems were active for the OER. Trends in activity are discussed as a function of the molar ratio in relation to the two types of catalyst systems, resulting in overpotentials for metal-adsorbed ZrP catalysts that were less than, or equal to, their metal-intercalated counterparts.
