Advances in Inference and Representation for Simultaneous Localization and Mapping (2021)

Simultaneous localization and mapping (SLAM) is the process of constructing a global model of an environment from local observations of it; this is a foundational capability for mobile robots, supporting such core functions as planning, navigation, and control. This article reviews recent progress in SLAM, focusing on advances in the expressive capacity of the environmental models used in SLAM systems (representation) and the performance of the algorithms used to estimate these models from data (inference). A prominent theme of recent SLAM research is the pursuit of environmental representations (including learned representations) that go beyond the classical attributes of geometry and appearance to model properties such as hierarchical organization, affordance, dynamics, and semantics; these advances equip autonomous agents with a more comprehensive understanding of the world, enabling more versatile and intelligent operation. A second major theme is a revitalized interest in the mathematical properties of the SLAM estimation problem itself (including its computational and information-theoretic performance limits); this work has led to the development of novel classes of certifiable and robust inference methods that dramatically improve the reliability of SLAM systems in real-world operation. We survey these advances with an emphasis on their ramifications for achieving robust, long-duration autonomy, and conclude with a discussion of open challenges and a perspective on future research directions.
White LED Based on YAG : Ce,Gd Phosphor and CdSe–ZnS Core/Shell Quantum Dots (2010)

Core/shell CdSe-ZnS quantum dots (QDs) with a peak emission wavelength of 618 nm and size of ~ 5.5 nm were synthesized by thermal deposition approach. High photoluminescence efficiency with a quantum yield of more than 48% has been achieved. Red-shift of a peak emission wavelength from 532 to 568 nm was realized by doping Gd <sup xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">3+</sup> ions into the YAG : Ce <sup xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">3+</sup> to substitute some Y <sup xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">3+</sup> ions. To compensate the poor color rendering index (CRI) of the YAG : Ce-based white light-emitting diode (LED) due to the lack of red spectral component, CdSe-ZnS QDs were blended into YAG : Ce <sup xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">3+</sup> , Gd <sup xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">3+</sup> phosphors. Prominent spectral evolution has been achieved by increasing the content of QDs. White LED combining a blue LED with the blends of phosphor and QDs with a weight ratio of 1:1, has been demonstrated with an improved CRI value of 90.

Normal-incidence infrared photoconductivity in Si p-i-n diode with embedded Ge self-assembled quantum dots (1999)

Room-temperature infrared photoconductivity in a single layer of Ge self-assembled quantum dots incorporated into silicon p-i-n diode is reported. An in-plane polarized photocurrent response with two bias controlled maxima at 2.9 μm and at 1.7 μm wavelength has been observed. The two kinds of absorption driven by reverse bias in opposite ways are ascribed to the intraband hole bound-to-continuum transition and to the interband excitonic transition.
Blue light exposure decreases systolic blood pressure, arterial stiffness, and improves endothelial function in humans (2018)

Whole body irradiation with visible blue light at real world doses improves blood pressure, endothelial function and arterial stiffness by nitric oxide released from photolabile intracutanous nitric oxide metabolites into circulating blood.
Light-assisted deep-trapping of holes in conjugated polymers (2009)

The injection of positive charge carriers (holes) into a single conjugated polymer chain was observed to be light-assisted. This effect may underlie critical, poorly understood organic electronic device phenomena such as the build-up of functional deeply trapped charge layers in polymer light emitting diodes. The charging/discharging dynamics were investigated indirectly by a variety of single molecule electro-optical spectroscopic techniques, including an "image-capture" approach.

<title>50-inch autostereoscopic full-color 3D TV display system</title> (1992)

This paper reports on a 50 inch diagonal autostereoscopic full-color 3-D TV display system that requires no special glasses and uses four color TV cameras with a 3-D color viewfinder, a high-resolution liquid crystal (LCD) video projector, and a specially designed lenticular screen. The resulting 3-D image is of high resolution, exceptionally bright and vividly three- dimensional. The key technologies supporting this 3-D TV display system are a 3-D image display method, a newly developed HDTV LCD color video projector with incredibly high resolution (4.5 million pixels), and a new type of lenticular screen with a `hollow structure.' Images from four color TV cameras are recorded by four professional VTRs with a time code signal, and are multiplexed, pixel by pixel, to form a vertical stripe image projected by the single LCD video projector behind the lenticular screen. Using this 3-D image display method, optical alignment between the projected stripe image and lenticular screen is both accurate and easily attained. The new lenticular screen with hollow structure has resulted in a reduced total screen weight and thickness with increased light transmittance.
Bibliographic Meta-Data Extraction Using Probabilistic Finite State Transducers (2007)

We present the application of probabilistic finite state transducers to the task of bibliographic meta-data extraction from scientific references. By using the transducer approach, which is often applied successfully in computational linguistics, we obtain a trainable and modular framework. This results in simplicity, flexibility, and easy adaptability to changing requirements. An evaluation on the Cora dataset that serves as a common benchmark for accuracy measurements yields a word accuracy of 88.5%, afield accuracy of 82.6%, and an instance accuracy of 42.7%. Based on a comparison to other published results, we conclude that our system performs second best on the given data set using a conceptually simple approach and implementation.
Isradipine and insulin sensitivity in hypertensive rats (1999)

The present study was designed to investigate the effect of a reduction in blood pressure, by using the calcium channel antagonist isradipine, on insulin sensitivity and vascular responses to insulin in conscious spontaneously hypertensive male rats (SHR). The rats were instrumented with intravascular catheters and pulsed Doppler flow probes to measure blood pressure, heart rate, and blood flows. Insulin sensitivity was assessed by the euglycemic-hyperinsulinemic clamp technique. Two groups of rats received isradipine at a dose of 0.05 or 0.15 mg. kg-1. h-1, whereas a third group received a continuous infusion of vehicle (15% DMSO). Both doses of isradipine were found to decrease mean blood pressure (-25 +/- 4 mmHg at the dose of 0.05 mg. kg-1. h-1 and -20 +/- 2 mmHg at the dose of 0.15 mg. kg-1. h-1) and to improve insulin sensitivity. Moreover, in the rats treated with the low dose of isradipine, we observed vasodilations in renal, superior mesenteric, and hindquarter vascular beds. In the untreated group, the euglycemic infusion of insulin (4 mU. kg-1. min-1) was found to cause vasoconstrictions in superior mesenteric and hindquarter vascular beds, but no changes in mean blood pressure, heart rate, or renal vascular conductance were found. In contrast, in the isradipine-treated groups, the same dose of insulin was found to produce vasodilations in the renal vascular bed and to abolish the vasoconstrictor responses previously observed. We concluded that short-term treatment with isradipine in SHR can lower blood pressure and improve insulin sensitivity, mainly through hemodynamic factors, as supported by experiments with hydralazine as a positive vasodilator control.
Syntheses of 2-Alkylpyrimidines by Dehydrocyclization and Dehydrogenation (1977)

Dehydrocyclization and dehydrogenation of trimethylenediamine and aldehyde to 2-alkylpyrimidine was studied on a Pt-Rh-Al2O3 catalyst in a stream of hydrogen gas at atomospheric pressure. The reaction was carried out between 290 and 410° in a flow system. The vapor of nonaqueous solvent (benzene or alcohols corresponding to the aldehyde) and nitrogen gas were examined as a diluent instead of water vapor which was used in a previous work. By the use of benzene and alcohol as a diluent, the yield of 2-alkylpyrimidine increased markedly to 48-81% without a decay in the catalyst activity. On the other hand, the decay was observed by the use of nitrogen gas as a diluent. Reaction conditions were also examined for the formation of 2-alkylpyrimidine from trimethylenediamine with alcohol, acid, or ester ; the principal product was 2-ethylpyrimidine from 3, 3'-diaminodipropylamine induced by disproportionation of trimethylenediamine. Therefore, the desired product (2-alkylpyrimidine) could not be obtained in a good yield.
GALLEX, a Measurement of Heterologous Association of Transmembrane Helices in a Biological Membrane (2003)

Whereas a variety of two-hybrid systems are available to measure the interaction of soluble proteins, related methods are significantly less developed for the measurement of membrane protein interactions. Here we present a two-hybrid system to follow the heterodimerization of membrane proteins in the Escherichia coli inner membrane. The method is based on the repression of a reporter gene activity by two LexA DNA binding domains with different DNA binding specificities. When coupled to transmembrane domains, heterodimeric association is reported by repression of beta-galactosidase synthesis. The LexA-transmembrane chimeric proteins were found to correctly insert into the membrane, and reproducible signals were obtained measuring the homodimerization as well as heterodimerization of wild-type and mutant glycophorin A transmembrane helices. The GALLEX data were compared with data recently gained by other methods and discussed in the general context of heteroassociation of single TM helices. Additionally, the formation of heterodimers between the TM domains of the alpha(4) and the beta(7) integrin subunits were tested. The results show that both homo- and heterodimerization of membrane proteins can be measured accurately using the GALLEX system.
DNA mimicry by a high-affinity anti-NF-κB RNA aptamer (2007)

The binding of RNA molecules to proteins or other ligands can require extensive RNA folding to create an induced fit. Understanding the generality of this principle involves comparing structures of RNA before and after complex formation. Here we report the NMR solution structure of a 29-nt RNA aptamer whose crystal structure had previously been determined in complex with its transcription factor target, the p50(2) form of NF-kappaB. The RNA aptamer internal loop structure has pre-organized features that are also found in the complex, including non-canonical base pairing and cross-strand base stacking. Remarkably, the free RNA aptamer structure possesses a major groove that more closely resembles B-form DNA than RNA. Upon protein binding, changes in RNA structure include the kinking of the internal loop and distortion of the terminal tetraloop. Thus, complex formation involves both pre-formed and induced fit binding interactions. The high affinity of the NF-kappaB transcription factor for this RNA aptamer may largely be due to the structural pre-organization of the RNA that results in its ability to mimic DNA.
Recoverable plasticity in penta-twinned metallic nanowires governed by dislocation nucleation and retraction (2015)

Abstract There has been relatively little study on time-dependent mechanical properties of nanowires, in spite of their importance for the design, fabrication and operation of nanoscale devices. Here we report a dislocation-mediated, time-dependent and fully reversible plastic behaviour in penta-twinned silver nanowires. In situ tensile experiments inside scanning and transmission electron microscopes show that penta-twinned silver nanowires undergo stress relaxation on loading and complete plastic strain recovery on unloading, while the same experiments on single-crystalline silver nanowires do not exhibit such a behaviour. Molecular dynamics simulations reveal that the observed behaviour in penta-twinned nanowires originates from the surface nucleation, propagation and retraction of partial dislocations. More specifically, vacancies reduce dislocation nucleation barrier, facilitating stress relaxation, while the twin boundaries and their intrinsic stress field promote retraction of partial dislocations, resulting in full strain recovery.
Electrochemical Reactivity and Design of NiP<sub>2</sub> Negative Electrodes for Secondary Li-Ion Batteries (2005)

We report the electrochemical study of cubic and monoclinic NiP2 polymorphs toward Li, as a candidate for anodic applications for Li-ion batteries. We found that the monoclinic form is the most attractive one performance-wise. Monoclinic NiP2 can reversibly uptake 5 lithium per formula unit, leading to reversible capacities of 1000 mAh/g at an average potential of 0.9 V vs Li+/Li°. From complementary X-ray diffraction (XRD) and HRTEM (high-resolution transmission electron microscopy) measurements, it was shown that, during the first discharge, the cubic phase undergoes a pure conversion process (NiP2 + 6 Li+ + 6e- → Ni° + 2Li3P) as opposed to a sequential insertion−conversion process for monoclinic NiP2. Such a different behavior rooted in subtle structural changes was explained through electronic structure calculations. Once the first discharged is achieved, both phases were shown to react with Li through a classical conversion process. More importantly, we report a novel way to design NiP2 electrodes with enhanced capacity retention and rate capabilities. It consists in growing the monoclinic NiP2 phase, through a vapor-phase transport process, on a commercial Ni-foam commonly used in Ni-based alkaline batteries. These new self-supported electrodes, based on chemically made interfaces, offer new opportunities to fully exploit the capacity gains provided by conversion reactions.
Dominant Inheritance of Overo Spotting in Paint Horses (1994)

Analysis of selected studbook records of the American Paint Horse Association, consisting of 687 foals sired by 13 overo stallions from non-overo mares, supports the inheritance of overo spotting as an autosomal dominant gene. More than one gene may control patterns registered as overo. Additional studies are necessary to explain the sporadic occurrence of overo spotting from nonspotted quarter horse parents and to confirm the inheritance of overo spotting in other breeds.
The effects of histamine, antihistamines, isoproterenol and theophylline on the Fc and complement receptor functions of polymorphonuclear leukocytes in asthmatic children. (1981)

The effects of histamine, antihistamines, isoproterenol and theophylline on the expressions of Fc and complement (C') receptors on the polymorphonuclear leukocytes (PMN's) were studied in 40 asthmatic children. Histamine in concentrations of 10(-13) to 10(-3), isoproterenol in 10(-5) to 10(-3) and theophylline in 5 X 10(-6) to 10(-4) were all capable of causing a dose-related suppression of Fc and C' receptor functions of PMN's. Either diphenhydramine or cimetidine alone could partially block the histamine-induced suppressive effect but combination of H1 and H2 receptor antagonists were required for complete abolishment.
Ubichip Virtual Machine and visualization of Spiking Neural Network Parameters (2010)

Since ages people have been wondering the inner workings of brain.\nThere is more and more information about processes involving particular\nbrain regions, yet synthesizing neural-networks in a large scale has always\nbeen a problem. Despite the fact that the popular desktop computer\nis becoming more powerful, simulating massively parallel computations\naways proved to be a challenge. Due to its genericness, in very specialized\nwork, such as neural networks, it is far better to design and use dedicated\narray of processors.\nSuch approach has been used in development of the Ubichip – a device\ndesigned specifically for such purposes. The design goal was to simplify the\nexecution elements to suit the needs of efficient neuron model algorithms\nemulation.\nAs with every development cycle of a complex tool there are many tasks\nthat may be carried out in parallel. This, of course, effects in allowing\nthe development team to shorten the cycle and provide the solution faster.\nThis however, requires a set of tools that will allow to prototype and verify\nwork progress against some set of basic rules.\nThe Ubichip was already supported by a toolkit named SpiNDeK,\nthat allowed to create networks and with the use of ModelSim simulate\nthe code. This solution for proof-checking the algorithms however proved\nto be cumbersome and due to many levels of indirection – slow. To increase\nefficiency when working with code, the programmer should not\nhave to wait endlessly watching the progress bars. To remedy this, improve\nefficiency and encourage more precise tuning and development of\nnew neuron-model algorithms the Ubichip Virtual Machine was born.\nAt first it was just meant to be a simple visualization tool, but as it\nturned out there was a missing link in the chain of tools available for the\nUbichip, which had to be filled.\nThus, in this work a virtual machine for the Ubichip has been developed,\nas well as a visualization tool that enables a convenient display of\nthe evolution of spiking neurons in a network.\ni

COMPACTEST: a method to generate compact test sets for combinational circuits (1993)

Heuristics to aid the derivation of small test sets that detect single stuck-at faults in combinational logic circuits are proposed. The heuristics can be added to existing test pattern generators without compromising fault coverage. Experimental results obtained by adding the proposed heuristics to a simple PODEM procedure and applying it to the ISCAS-85 and fully-scanned ISCAS-89 benchmark circuits are presented to substantiate the effectiveness of the proposed heuristics.< <ETX xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">></ETX>
Wet Brewers Grains for Lactating Dairy Cows During Hot, Humid Weather (1994)

Twenty lactating Jersey cows were offered diets containing 0, 15, or 30% wet brewers grains or 30% wet brewers grains plus liquid brewers' yeast during hot, humid weather. The DMI was not different, even though diets with 30% wet brewers grains contained only 35.5% DM and approximately 50 versus 36.8% NDF for the control diet. Yields of milk and FCM did not differ for cows offered the control diet versus wet brewers grains or diets with 15 versus 30% wet brewers grains, but milk yield for diets with 30% wet brewers grains was greater with added liquid brewers' yeast than without it. Milk fat percentage was not different, but milk protein percentage was lower, for diets with wet brewers grains than for controls and for 30% wet brewers grains than for 15% wet brewers grains. Serum urea N was lower for control cows than for cows receiving the diets with wet brewers grains. Feed cost per cow was lower for wet brewers grains versus the control diet, and income over feed cost was greater for diets with 30 versus 15% wet brewers grains. Large quantities of wet brewers grains can be added to the diet during hot weather without depressing DMI.
