Task performance tests on inserting the bolts by an experimental system for power distribution line maintenance - grope action under compliance control (2012)

We are developing semi-autonomous robot system for power distribution line maintenance tasks to ensure worker's safety and improve efficiency of task performance. This robot system works with task level instructions, for example, "Insert the bolt". In this paper, we describe a task performance test on "Insert the bolt" in arm-tie exchange task in installing switch gear. When human gives the task instruction "Insert the bolt", the robot system 1) grasps the bolt with gripper, 2) recognizes the bolt hole using camera and laser range finder, 3) approaches the bolt hole, 4) gropes along the bolt hole with the bolt under compliance control, and insert the bolt to the bolt hole.
Fatal single vehicle motorcycle crashes (2001)

More than 38,000 motorcyclists have died in single vehicle motorcycle crashes between 1975 and 1999. Motorcyclist\nfatalities in single vehicle crashes decreased each year from 1990 to 1996, reaching a historic low of 937 in 1996 and\nagain in 1997. In 1998 and again in 1999 the fatalities increased to 1,042 (11.2%) in 1998 and to 1,140 (9.4%) in 1999.\nThe overall increase in motorcyclist fatalities from 1997 to 1999 was 203 (21.7%).\nMotorcyclist fatalities in single vehicle crashes account for about 45 percent of all motorcyclist fatalities. With such a\nhigh percentage of motorcyclist fatalities in single vehicle motorcycle crashes, this report was written to provide insight\ninto the possible causes for these fatalities.\n

DeepCut: Joint Subset Partition and Labeling for Multi Person Pose Estimation (2015)

This paper considers the task of articulated human pose estimation of multiple people in real world images. We propose an approach that jointly solves the tasks of detection and pose estimation: it infers the number of persons in a scene, identifies occluded body parts, and disambiguates body parts between people in close proximity of each other. This joint formulation is in contrast to previous strategies, that address the problem by first detecting people and subsequently estimating their body pose. We propose a partitioning and labeling formulation of a set of body-part hypotheses generated with CNN-based part detectors. Our formulation, an instance of an integer linear program, implicitly performs non-maximum suppression on the set of part candidates and groups them to form configurations of body parts respecting geometric and appearance constraints. Experiments on four different datasets demonstrate state-of-the-art results for both single person and multi person pose estimation. Models and code available at http://pose.mpi-inf.mpg.de.
New Methods for Controlled Injection of Steam Into Multiple Sands (1986)

ABSTRACT Chevron has been employing two new completion methods to control steam injection into multiple oil-bearing horizons using a single injection well. The two methods, parallel tubing injection and limited entry injection, are used to improve steam utilization and to reduce the need to drill new injection wells. One of the methods used previously was concentric injection in which steam is injected down two concentric pipes placed inside the wellbore and thereby distributed to two separate sands. The outer pipe can be the well casing itself. This method, however, proved unsatisfactory because one of the strings became plugged due to scale buildup. As a result, injection into both sands was no longer possible. For this reason, the concentric injection method is no longer used. Instead, parallel tubing injection and limited entry injection methods are currently used. This paper reviews the concentric injection method and presents conceptual details of the two new methods. Theoretical calculations supporting application of these methods are also presented.
Integrating Business Opportunities in Contiguous Economies: A Note on the Low-Cost Manufacturing Enclaves in Batam Island, Indonesia (2005)

In the 1990s, Singapore established several industrial parks in Asia to capitalize on the rising demand for low-cost manufacturing centers. These parks were envisioned as attractive investment enclaves, boasting a combination of location-specific advantages and world-class infrastructure, further complemented by Singapore's ability to negotiate investment concessions at an inter-government level. Since the establishment of Singapore's Batamindo Industrial Park (BIP) in Riau, Indonesia, similar sites offering more competitive cost structures have emerged. The mushrooming of industrial parks is seen as an indication of Batam attractiveness as an investment location, reflecting the (Singapore) government’s long-term vision of twinning the contiguous Singapore-Riau economies. This paper considers the success of BIP vis-a-vis two non-Singaporean competitor parks, Panbil Industrial Estate (PIE) and Tunas Industrial Estate (TIE). Evidence from on-site surveys and interviews are presented. This paper concludes that BIP must contend with rising competition from the newer industrial developments, despite retaining certain first-mover advantages.
Factors associated to resistant depression (2007)

To study the impact of eating disorders (EDs) on the severity of bipolar disorder (BD).The Structured Clinical Interview for DSM-IV Axis I (SCID-I), Young Mania Rating Scale (YMRS), Hamilton Depression Rating Scale (HAM-D-17), Hamilton Anxiety Rating Scale (HAM-A), Global Assessment of Functioning (GAF), Clinical Global Impression (CGI), and the World Health Organization Quality of Life Assessment (WHOQOL-BREF) were used. Clinical and sociodemographic data were also collected.Among the 356 bipolar patients included in this study, 19 (5.3%) were also diagnosed with ED. Of these, 57.9% had bulimia nervosa (BN) and 42.1% had anorexia nervosa (AN). Among ED patients, 94.7% were female. Bipolar patients with EDs presented with lower scores in the mental health domain of the WHOQOL-BREF, higher scores of depressive symptoms, and more psychiatric comorbidities.ED comorbidities imposed important negative outcomes in bipolar patients. This finding suggests that attention should be given to the presence of EDs in BD patients and that better treatments focused on this population should be developed.Estudar a influência dos transtornos alimentares (TA) na gravidade do transtorno bipolar (TB).Foram utilizadas a Entrevista Clínica Estruturada para o Eixo I do DSM-IV (SCID-I), a Escala de Young para Avaliação da Mania (YMRS), a Escala de Hamilton para Avaliação da Depressão (HAM-D-17), a Escala de Hamilton para Avaliação da Ansiedade (HAM-A), a Avaliação do Funcionamento Global (GAF) e a Escala Breve de Avaliação da Qualidade de Vida da Organização Mundial da Saúde (WHOQOL-BREF). Os dados clínicos e sociodemográficos também foram coletados.Entre os 355 pacientes com TB incluídos neste estudo, 19 (5,3%) também foram diagnosticados como portadores de TA. Destes, 57,9% tinham bulimia nervosa (BN) e 42,1% anorexia nervosa (AN). Dentre os pacientes com TA, 94,7% eram do gênero feminino. Os pacientes portadores de TB e TA apresentaram escores mais baixos do domínio saúde mental da WHOQOL-BREF, escores mais elevados de sintomas depressivos e mais comorbidades psiquiátricas.A presença de comorbidades com TA acarreta importantes desfechos negativos em pacientes bipolares. Este achado sugere que atenção deva ser dada à presença de TA em pacientes com TB e que melhores tratamentos focados nessa população sejam desenvolvidos.
Presence of P2X1 Purinoceptors in Human Platelets and Megakaryoblastic Cell Lines (1997)

Human platelets are thought to possess at least two subtypes of purinoceptor, one of which, coupled to G-proteins, could be the P2Y1 receptor (Leon et al. 1997). However, it has been suggested that the unique rapid calcium influx induced by ADP in platelets could involve P2X1 ionotropic receptors (MacKenzie et al. 1996) and the aim of this study was thus to investigate the presence of P2X purinoceptors in platelets and megakaryoblastic cells. Using PCR experiments, we found P2X1 mRNA to be present in human platelets and megakaryoblastic cell lines. In platelets, the selective P2X1 agonist alphabetaMeATP induced a rise in intracellular calcium only in the presence of external calcium and this effect was antagonized by suramin and PPADS. Repeated addition of alphabetaMeATP desensitized the P2X1 purinoceptor but only slightly affected the ADP response, while no calcium response to alphabetaMeATP was observed in megakaryoblastic cells. These results support the existence of functional P2X1 purinoceptors on human platelets and the presence of P2X1 transcripts in megakaryoblastic cell lines.
Identification and characterization of human NR4A2 polymorphisms in attention deficit hyperactivity disorder (2005)

Attention deficit hyperactivity disorder (ADHD) is a highly heritable and common disorder thought to arise, in part, from alterations in dopamine function. NR4A2, or Nurr1, is an orphan nuclear receptor implicated in the development of dopaminergic cells of the ventral tegmental area (VTA) and the substantia nigra (SN). Dopaminergic cells of the VTA provide innervation to the prefrontal cortex, believed to be of major importance in the etiology of ADHD, suggesting that NR4A2 is a potential candidate gene for ADHD susceptibility. This study aimed to identify polymorphisms in NR4A2 and test their association to ADHD. Database analysis revealed a CA repeat polymorphism in the 3' UTR of NR4A2 that was confirmed by PCR. SSCP screening revealed a common DeltaC polymorphism, 254 bp 5' to the transcriptional start site. These polymorphisms were tested for an association with ADHD in both a case control study of individuals from the Milwaukee Longitudinal Study of ADHD (103 cases and 66 controls), and in 35 families composed of trios or affected sib pairs (ASP) with ADHD. Functional effects of the promoter polymorphism were tested in vitro. The non-deleted allele was significantly more active in undifferentiated SK-N-MC cells compared to differentiated SK-N-MC and HeLa cells while a trend for increased activity for the DeltaC allele was observed in undifferentiated SK-N-MC cells. Identification of these polymorphisms may aid future candidate gene studies in disorders with altered dopamine signaling, such as schizophrenia Parkinson's disease and ADHD.
The role of polyphenols in poultry nutrition (2020)

In the last two decades, poultry and animal industries became increasingly interested in using plant-based feed supplements, herbs and their derivatives to retain or enhance their health and productivity. These health benefits for the host mainly attributed to the secondary plant metabolites, namely polyphenols. Polyphenols are renowned for their antioxidant, immunomodulatory, anti-mutagenic and anti-inflammatory properties. However, despite these advantages of polyphenols, they have been characterized by poor absorption in the gut and low concentration in target cells that compromise their role as effective antioxidants. The low bioavailability of polyphenols necessitates the need for further investigations to harness their full potential in poultry farms. This review is existing evidence about the bioavailability of polyphenols and their antioxidant, immunomodulatory, antimicrobial, detoxification properties and their impacts on poultry performance.

Increased solubility of molecular hydrogen in UV-exposed germanosilicate fibers (2006)

Spectral properties of photoinduced fiber Bragg gratings written in germanosilicate fibers and subjected to hydrogen loading at a pressure of 150-170 MPa have been studied. It was observed, for the first time to our knowledge, that hydrogen dissolution in the glass network at such high pressures leads not only to a Bragg wavelength shift but also to a considerable alteration of the grating reflectivity. The relative magnitude of the latter effect is independent of the dissolved hydrogen concentration and is defined mainly by the core glass properties and the UV-irradiation conditions. The alteration of the grating reflectivity observed experimentally is explained by increased solubility of molecular hydrogen in UV-exposed germanosilicate glass.

Molecular Assembly of an Achiral Phosphine and a Chiral Primary Amine: A Highly Efficient Supramolecular Catalyst for the EnantioselectiveMichael Reaction of Aldehydes with Maleimides (2013)

A combined catalyst system of a cinchonidine-derived primary amine and triphenylphosphine (CD-NH2 /PPh3 ) exhibited high catalytic performance in the Michael reaction of aldehydes with maleimides, thereby affording the corresponding functionalized aldehydes in excellent yields (up to 99 %) and enantioselectivities (>99 % ee). More interestingly, the significance of the phosphine in enhancing the enantioselectivities in the chiral-primary-amine-catalyzed Michael reaction was revealed. Furthermore, we explored the origin of the reaction mechanism in the Michael addition promoted by the dual organocatalytic system. On the basis of experimental results and spectroscopic analysis, such as UV/Vis, fluorescence emission (FL), NMR, and circular dichroism (CD) spectroscopy, as well as ESI-MS, we found that the molecular assembly of phosphine and primary amine played a crucial role in this enantioselective reaction, in which a possible supramolecular complex was formed as an effective chiral catalyst through noncovalent molecular interactions of a cinchona alkaloid-derived primary amine with triphenylphosphine.

Heterodyne interferometer with two-wave mixing in photorefractive crystals for ultrasound detection on rough surfaces (1996)

Heterodyne interferometers using two-wave mixing in photorefractive cubic crystals for ultrasound detection on rough surfaces are demonstrated. The speckled scattered beam from a rough surface sample interferes with a planar coherent pump beam inside a photorefractive crystal. A third frequency-shifted beam is used to read the grating. The diffracted readout beam and the transmitted signal beam are wavefront matched, resulting in an optimal heterodyne interference signal. The signal to noise ratio for the two commonly used crystallographic configurations with cubic crystals, G∥〈110〉∥ and G∥〈001〉, where G is the grating wave vector, are investigated. Very good sensitivity is demonstrated for the detection of small amplitude ultrasonic surface displacements.
Label Switched Path (LSP) Ping for IPv6 Pseudowire FECs (2011)

The Pseudowire FEC sub-TLVs for the Target FEC Stack in the LSP Ping
mechanism are implicitly defined for IPv4 Provider Edge (PEs) routers.
There is, however, a degree of potential ambiguity in the
specification of these sub-TLVs since the address family is not
specified but could be inferred from the length. This document updates
RFC4379 to explicitly constraint these sub-TLVs for IPv4 LDP sessions,
and extends Pseudowire LSP Ping to the IPv6 scenario where an IPv6 LDP
session is used to signal the Pseudowire (i.e., where the Sender's
and Receiver's IP addresses are IPv6 addresses.) This is done by
defining two new LSP Ping sub-TLVs for IPv6 Pseudowire FECs.
Analytic free-form lens design for tracking integration in concentrating photovoltaics (2012)

In this work the concept of tracking integration in concentrating photovoltaics (CPV) is revisited and developed further. With respect to conventional CPV, tracking integration eliminates the clear separation between stationary units of optics and solar cells, and external solar trackers. This approach is capable of further increasing the concentration ratio and makes high concentrating photovoltaics (&lt; 500x) available for single-axis tracker installations. The reduced external solar tracking effort enables possibly cheaper and more compact installations. Our proposed optical system uses two laterally moving plano-convex lenses to achieve high concentration over a wide angular range of &plusmn;24&deg;. The lateral movement allows to combine both steering and concentration of the incident direct sun light. Given the specific symmetry conditions of the underlying optical design problem, rotational symmetric lenses are not ideal for this application. For this type of design problems, a new free-form optics design method presented in previous papers perfectly matches the symmetry. It is derived directly from Fermat's principle, leading to sets of functional differential equations allowing the successive calculation of the Taylor series coeficients of each implicit surface function up to very high orders. For optical systems designed for wide field of view and with clearly separated optical surfaces, this new analytic design method has potential application in both fields of nonimaging and imaging optics.
Hindpaw Withdrawal from a Painful Thermal Stimulus after Sciatic Nerve Compression and Decompression in the Diabetic Rat (2012)

Chronic compression of the diabetic rat sciatic nerve increases (worsens) the threshold to heat (pain) perception. Decompression reverses this effect (improves nociception).
Use of low power EM radar sensors for speech articulator measurements (1997)

Quantitative immune phenotyping: a new dimension for the monitoring of haemopoietic malignancies. (1994)

Quantitative data provided by flow cytometers are as yet not fully exploited due to the lack of standardization. However, fluorescence standardization systems are now available which allow the measurement of antigen density on a routine basis and the present review focuses on the interest of such quantitative techniques for the monitoring of haemopoietic malignancies. Antigen quantitation: (i) permits a more objective characterization of positivity, especially in the case of weakly expressed antigens; (ii) facilitates the analysis of complex populations, since certain antigens are expressed at different levels on different cell subsets; (iii) provides new data contributing to a more precise definition of cell differentiation; (iv) is of value to ascertain malignancy from the detection of aberrant antigen densities on putative neoplastic cells; (v) provides additional parameters suitable for the evaluation of residual disease and for the monitoring of immunological therapeutic regimens; (vi) contributes to prognosis. Quantitation of antigen densities should therefore be included in the routine study of haemopoietic malignancies.
