Issues and Strategies for Robotic Object Manipulation in Domestic Settings (2004)

Abstract — Many robotic tasks such as autonomous navigation, human-machine collaboration, object manipulation and grasping facilitate visual information. Some of the major reasearch and system design issues in terms of visual systems are robustness and flexibility. In this paper, we present a number of visual strategies for robotic object manipulation tasks in natural, domestic environments. Given a complex fetch-and-carry type of tasks, the issues related to the whole detect-approachgrasp loop are considered. Our vision system integrates a number of algorithms using monocular and binocular cues to achieve robustness in realistic settings. The cues are considered and used in connection to both foveal and peripheral vision to provide depth information, segment the object(s) of interest in the scene, object recognition, tracking and pose estimation. One important property of the system is that the step from object recognition to pose estimation is completely automatic combining both appearance and geometric models. Rather than concentrating on the integration issues, our primary goal is to investigate the importance and effect of camera configuration, their number and type, to the choice and design of the underlying visual algorithms. Experimental evaluation is performed in a realistic indoor environment with occlusions, clutter, changing lighting and background conditions. I.
Identification and Characterization of the Arabidopsis PHO1 Gene Involved in Phosphate Loading to the Xylem (2002)

The Arabidopsis mutant pho1 is deficient in the transfer of Pi from root epidermal and cortical cells to the xylem. The PHO1 gene was identified by a map-based cloning strategy. The N-terminal half of PHO1 is mainly hydrophilic, whereas the C-terminal half has six potential membrane-spanning domains. PHO1 shows no homology with any characterized solute transporter, including the family of H(+)-Pi cotransporters identified in plants and fungi. PHO1 shows highest homology with the Rcm1 mammalian receptor for xenotropic murine leukemia retroviruses and with the Saccharomyces cerevisiae Syg1 protein involved in the mating pheromone signal transduction pathway. PHO1 is expressed predominantly in the roots and is upregulated weakly under Pi stress. Studies with PHO1 promoter-beta-glucuronidase constructs reveal predominant expression of the PHO1 promoter in the stelar cells of the root and the lower part of the hypocotyl. There also is beta-glucuronidase staining of endodermal cells that are adjacent to the protoxylem vessels. The Arabidopsis genome contains 10 additional genes showing homology with PHO1. Thus, PHO1 defines a novel class of proteins involved in ion transport in plants.
Discharge Characteristics and Detectability of Metal Particles on the Spacer Surface in Gas-Insulated Switchgears (2021)

Metal particles and dirty contaminants on the spacer surface are mainly considered to be the critical factor in sudden flashovers. Understanding the discharge characteristics as well as the detectability of metal particles in the gas-insulated switchgear (GIS) will be helpful in improving its safety and reliability. In this paper, a high-sensitivity measurement system based on cross-reference pulse current (PC) and ultra-high-frequency (UHF) methods was established. The PC and UHF signals generated by partial discharges (PDs) of metal particles of different lengths (<i>&#x03A6;</i> &#x003D; 0.5 mm, <i>L</i> &#x003D; 2, 5, 8, and 10 mm) at different positions on a real spacer surface were studied. The PD characteristics and detectability of the metal particles on the spacer surface were obtained while the detection limitation was also discussed. It is found that under PD test condition, the apparent charge of the PDs is less than 1 pC for particles shorter than 5 mm, and the conventional PD detection method have limitations in detecting these short particles on the spacer surface. Under operation condition, only the apparent charge of particles longer than 8 mm can exceed 1 pC, which means it is difficult to detect the particles shorter than 8 mm in field. However, the result indicates that even the 5 mm long particle will be harmful to the GIS. Meanwhile, it is also been found that the detection sensitivity also has a great influence on the judgement of PD severity. This study is of great interest for understanding the PD characteristics, discharge levels, and detectability of short metal particles on spacer surface.
Multi-disk management algorithms (1987)

We investigate two schemes for placing data on multiple disks. We show that declustering (spreading each file across several disks) is inherently better than clustering (placing each file on a single disk) due to a number of reasons including parallelism and uniform load on all disks.
TrigSense: Accelerometer triggered audio sensing for traffic condition monitoring (2013)

Rate of honking combined with the average vehicular movement can coarsely estimate the traffic condition of a street in an urban area of developing nations. Recently a lot of work is done on participatory sensing using users' mobile phones. This leads to a concern of battery usage in the mobile phones. In this paper, we propose a multimodal approach for triggered sensing, where the low power sensors are used to trigger power hungry sensors for traffic condition estimation. Instead of turning on all the sensors, the low power consuming sensors like accelerometer is used to trigger the high power consuming sensors like microphone by applying a predefined logic. Feature extraction of the audio is done on the mobile device. The feature data and a simultaneously generated metadata xml file containing the location related information and time-stamp are posted to a backend server for further processing. A decision tree based approach is proposed for deriving the traffic condition using horn detection. Based on those decisions, application for traffic condition monitoring are created and updated for public access. Experimental results show the effectiveness of triggered audio sensing in terms of energy savings (upto 50%) on the mobile device and also in the reduction of the overall processing at the server.

nm23-H1 expression and loss of heterozygosity in colon adenocarcinoma (2004)

These findings suggest that nm23-H1 protein expression in early stages may have a role in suppressing metastasis in sporadic colon cancer, whereas at a later stage both reduced nm23-H1 protein expression and LOH of the nm23-H1 gene may play role in colon cancer progression and metastasis.
The Effects of Yellow Soybean, Black Soybean, and Sword Bean on Lipid Levels and Oxidative Stress in Ovariectomized Rats (2010)

Soy isoflavones have been reported to decrease the risk of atherosclerosis in postmenopausal women. However, the effects of dietary consumption of soybean have not been explored. In this study, we evaluated the effects of consuming yellow soybeans, black soybeans (Glycine max), or sword beans (Canavalia gladiate) on lipid and oxidative stress levels in an ovariectomized rat model. Forty-seven nine-week-old female rats were ovariectomized, randomly divided into four groups, and fed one of the following diets for 10 weeks: a diet supplemented with casein (NC, n = 12), a diet supplemented with yellow soybean (YS, n = 12), a diet supplemented with black soybean (BS, n = 12), or a diet supplemented with sword bean (SB, n = 11). Plasma triglyceride (TG) levels in the BS and SB groups were significantly lower than that in the NC group. Notably, the BS group had significantly lower plasma total cholesterol (TC), and low-density lipoprotein cholesterol (LDL-C) levels than the other groups. Hepatic total lipid levels were significantly lower in the YS and SB groups, and cholesterol levels were significantly lower in the SB group than in the NC group. Superoxide dismutase (SOD) and catalase (CAT) activities were significantly higher in the groups fed beans compared to the NC group. Hepatic thiobarbituric acid reactive substances (TBARS) levels were also significantly lower in the BS and SB groups than the NC group. In conclusion, our results suggest that consumption of various types of beans may inhibit oxidative stress in postmenopausal women by increasing antioxidant activity and improving lipid profiles. Notably, intake of black soybean resulted in the greatest improvement in risk factors associated with cardiovascular disease.
Optimal integration for biodiesel production using bioethanol (2012)

The production of biodiesel from algae is optimized using bioethanol following four different transesterification paths: alkali, enzymatic, and heterogeneous catalysts and supercritical conditions. The reactors are modeled using response surface methodology based on experimental results from the literature. These reactor models are implemented together with short‐cut methods for the other equipment (distillation columns, gravity separators, etc.) in order to recover the ethanol, separate the polar and nonpolar phases, and purify the glycerol and biodiesel produced to formulate the problem as a superstructure of alternatives. The aim is to simultaneously optimize and heat integrate the production of biodiesel using ethanol in terms of the reaction technology and the operating conditions. The optimal conditions in the reactors differ from the ones traditionally used because these results take the separation stages into account. In terms of the optimal process, the alkali catalyzed process is the most profitable, while the enzymatic one is also promising due to the lower consumption of energy and water, although it requires significant enzyme cost. © 2012 American Institute of Chemical Engineers AIChE J, 59: 834–844, 2013
Synchrotron-radiation measurements of forbidden reflections in silicon and germanium (1980)

The (442) and (662) reflections in both Si and Ge were measured using synchrotron radiation from the Wilson 12-GeV Synchrotron. These reflections, which are basis forbidden in diamond-structure materials, arise from two distinct effects: antisymmetric charge buildup due to covalent bonding of the valence electrons and anharmonic thermal vibrations of the core electrons. Because these reflections are sensitive only to deviations from a centrosymmetric charge density, their integrated intensities are extremely small. The measured structure factors for these reflections at room temperature were $F(442)=0.042\ifmmode\pm\else\textpm\fi{}0.003$, $F(622)=0.005\ifmmode\pm\else\textpm\fi{}0.004$, and $F(442)=0.0630\ifmmode\pm\else\textpm\fi{}0.0016$, $F(622)=0.0558\ifmmode\pm\else\textpm\fi{}0.0023$ in silicon and germanium, respectively. The anharmonic contribution can be removed from these values leaving the scattering amplitude due solely to the bond change. We compare these values to empirical and theoretical predictions. New techniques utilizing the inherent properties of synchrotron radiation will also be discussed.
Optimization Models for Feature Selection of Decomposed Nearest Neighbor (2015)

The traditional k-nearest neighbor (KNN) method classifies an object by the majority vote of its neighbors, and only one parameter k is to be optimized. We propose a decomposed version of the KKN (DKNN) method, which classifies an unseen object based on the distances to the centroids of the KNNs. DKNN has a training process to learn the local-optimafree distance metric by solving a convex optimization problem. The optimization problem not only learns a metric that minimizes classification errors and maximizes the margin between intraclass and interclass distances. In addition, it also selects important features and removes irrelevant features when L1 regularization is incorporated in the optimization model. The feature selection component is extremely useful for high-dimensional classification problems. Tested on public datasets, the proposed DKNN is competitive and often outperforms traditional machine learning algorithms.
Exploring the application of synthetic audio in training keyword spotters (2021)

The study of keyword spotting, a subfield within the broader field of speech recognition that centers around identifying individual keywords in speech audio, has gained particular importance in recent years with the rise of personal voice assistants such as Alexa. As voice assistants aim to rapidly expand to support new languages, keywords, and use cases, stakeholders face the issue of limited training data for these unseen scenarios. This paper details some initial exploration into the application of Text-To-Speech (TTS) audio as a "helper" tool for training keyword spotters in these low-resource scenarios. In the experiments studied in this paper, the careful mixing of TTS audio with human speech audio during training led to a reduction of over 11% in the detection-error-tradeoff (DET) area under the curve (AUC) metric.

Influence of Doping and Tunneling Interface Stoichiometry on n+In0.5Ga0.5As/p+GaAs0.5Sb0.5 Esaki Diode Behavior (2016)

In this work, we study the influence of molecular beam epitaxy (MBE) growth parameters on the behavior of a staggered band gap n+In 0.5 Ga 0.5 As/p+GaAs 0.5 Sb 0.5 Esaki diodes. We first first show that a careful doping is required to avoid any crystal defects. Then the influence of the doping concentration on the Band to Band Tunneling (BTBT) is discussed. At the end, we show that a careful monitoring of the MBE growth allows thin and abrupt n+In 0.5 Ga 0.5 As/p+GaAs 0.5 Sb 0.5 tunneling interfaces where BTBT behavior in this case is independent of the III-V interface stoichiometry
Carbon-13 Fourier transform nuclear magnetic resonance studies of fractionated Candida utilis membranes (1975)

13C Fourier transform nuclear magnetic resonance has been used to study the lipid structure and dynamics of fractionated Candida utilis cell membranes. Measurements of the spin-lattice relaxation times indicate the existence of mobility gradients in the direction of increased mobility from the glycerol backbone toward the terminal methyl group of the fatty acid and toward the choline methyls. The temperature dependence of the relaxation times gives activation energies of approximately 4-6 kcal/mol for the rotations about various carbon-carbon bonds which determine the relaxation rates. In general, comparison with data which have been reported for artificial membrane systems indicates that the contributions of protein-lipid interactions to the T1 gradient are of negligible importance in the yeast membrane system. A dynamical model for the motion about bonds near unsaturated bonds which determined the relaxation of the unsaturated carbons is also proposed. Measurements of chemical shifts with temperature also exhibit a correlation with chain position. On the basis of these data a correlation of deltaE, the energy difference between gauche and anti conformations for gamma carboms, with chain position is inferred. In addition, an estimate of 1.2 kcal/mol can be obtained for deltaE for carbons near the end of the fatty acid chain. This value indicates that intermolecular interactions contribute substantially to deltaE since a value of approximately 0.5 kcal/mol can be ascribed to intramolecular interactions.
Mucin gel formed by tumorigenic squamous lung carcinoma cells has Le(a)-X oligosaccharides and excludes antibodies from underlying cells. (1992)

Cells of cloned lines of human squamous lung carcinomas elaborate large glycoproteins that are associated with their tumorigenic potential. Two groups of clones (called Le(a)-X-positive and Le(a)-X-negative) were studied that either do or do not express the Le(a)-X oligosaccharide associated with large glycoproteins and mucins secreted by these clones. Le(a)-X-positive cells elaborate a mucin gel complex associated with their apical surfaces, which appears as a mosaic of extracellular plates. Clones of this type are tumorigenic in nude rodents when injected s.c. or when introduced into the lungs via intrabronchial aerosol. By contrast, the Le(a)-X-negative clones do not form extracellular plates and are not tumorigenic in the lungs or subcutaneously. We demonstrate that the extracellular plates of Le(a)-X-positive cells exclude antibodies from interacting with the underlying squamous lung carcinoma cells and may therefore exert an immunoprotective effect. In support of this possibility it was found that: (a) There is a substantial inflammatory cell infiltrate associated with regressing nodules of Le(a)-X-negative cells in nude rodent lung and subcutaneous nodules, while there is no observable infiltration associated with progressing Le(a)-X-positive tumors. (b) In the brain (an immunoprivileged site) tumors develop and progress when either Le(a)-X-negative or -positive cells are introduced.
Hemodynamic effects of cadralazine or chlorthalidone in verapamil-treated elderly hypertensives. (1994)

Fourteen hypertensives aged > 66-77 years, whose diastolic blood pressure (DBP) was > or = 95 mmHg at the end of 1-month treatment with verapamil 240 mg SR, took part in this clinical-hemodynamic study. Patients were randomized to add the long-acting hydralazine derivative, cadralazine, 10 mg once daily, or chlorthalidone 25 mg once daily for 1 month each, to their previous verapamil regimen, according to a double-blind crossover design. Echo-Doppler hemodynamics were performed before starting verapamil, 1 month after verapamil and then after each phase of the crossover study. A significant reduction in DBP both in supine and upright position was observed with both drugs, while the reduction in systolic blood pressure was not significant. Criteria for a satisfactory response were DBP < or = 90 mmHg or a DBP reduction > or = 10 mmHg; this goal was achieved in 9 patients with cadralazine, 9 patients with chlorthalidone, 5 patients with both. The hemodynamic study in responders showed that both cadralazine and chlorthalidone acted through a reduction of peripheral resistances without inducing reflex tachycardia. Thus, cadralazine and chlorthalidone represent a suitable second-step treatment in elderly hypertensives insufficiently controlled by verapamil monotherapy: both drugs act through a reduction in total peripheral resistance (TPR).
Transparent Rectangular Patch Antenna Using Square Metal Mesh Transparent Electrode (2018)

This paper reports the transparent electrode, which would be applied to transparent displays and smart glasses. Herein, a squared metal mesh with the most widely used copper wire in microwaves is studied for the alternating thin-film-type transparent and conducting indium tin oxide(ITO), with a low conductivity(sheet resistance > 5 Ω/sq.). The electromagnetic performance of a patch antenna with metal mesh is analyzed. This paper presents the results of the optical(OT, optical transparent) and electrical(sheet resistance) characteristics of a squared metal mesh, which is a basic design. To improve the OT, copper wire(w=0.2 mm) is used in fabricating the squared metal mesh and the relationship between the OT and the antenna performance(radiation gain, radiation pattern) was analyzed according to the mesh size(l=1, 2 mm). The measurement results show that the antenna performance and the optical characteristic are in inverse proportion to each other. In real applications, the optical and electrical characteristics, and the costs of production are to be considered.
Response to Letter by Hotermans et al (2006)

We thank Hotermans and colleagues for their insightful comments. In general, we concur with their comments. Despite robust and meticulous experimental procedure, clinical rTMS trials on both individuals with normal and/or pathological conditions show a large inter-/intrasubject variability in cortical excitability and associated motor behaviors. ] Because we have strictly adhered to the established rTMS guideline 4 and used robust inclusion criteria for safety reasons, no undesirable effect was seen in our patients during or after rTMS. Currently, a very large number of rTMS techniques and experimental paradigms have been implemented and are under investigation. It is only through scrupulous experimental studies, such as the one we have done, that we will be able to determine the best safe and effective intervention methods to help patients.

Infrared magnetospectroscopy of GaAs at magnetic fields up to 150 T (1989)

A study of the nonparabolic and anisotropic nature of the ${\ensuremath{\Gamma}}_{6}$ conduction band of GaAs is presented for magnetic fields up to 150 T. Spin splitting of the cyclotron resonance and donor-shifted cyclotron-resonance transitions are observed in the transmission spectra. A five-level P\ensuremath{\cdot}p model that includes resonant and nonresonant polaron effects is developed and compared to experiment. Reasonable agreement between theory and experiment is found.
Insertion sociale/Emploi (1983)

In this document, the 1974 Inter-Society Commission for Heart Disease Resources (ICHD) report, Implantable Cardiac Pacemakers, has been revised and updated to emphasize the increased complexity of present-day pacing, to propose realistic guidelines for various aspects of pacing practivce, and to identify the resources needed for delivery of this important mode of health care. The first section of the report describes the several types of pacemakers currently available, how they function, and how and to what purpose they may be modified through noninvasive programming. Recommendations are given for a modified and updated version of the widely accepted ICHD code for identification of pacing modes. The emphasis of the second section of the report is on physical and personnel resources. Matters considered in some depth include the training and qualification of the various medical, technical, and paramedical specialists involved in an implantation procedure; requirements for, and methods of achieving, short and long-term surveillance of pacemaker patients; and the role of the hospital, the manufacturers, and the FDA in this new era of complex dual-chamber, multiprogrammable pacemakers.
Restored Expression of Fragile Histidine Triad Protein and Tumorigenicity of Cervical Carcinoma Cells (2000)

Restoration of Fhit expression does not suppress anchorage-independent growth or tumorigenicity of cervical carcinoma cell lines. However, it remains possible that FHIT inactivation may be important early in cervical tumor progression or that FHIT may suppress tumorigenesis in ways distinct from those measured by the assays employed in this study.
