A framework based on vision sensors for the automatic management of exchange parking areas (2010)

This paper proposes a framework for the automatic management of exchange parking areas, usually located in the periphery of large cities. These parks are used for medium/long period stops of private or public vehicles and the subsequent sorting of passengers to public transportation networks. The objective of this paper is to analyze and stress the potential of a framework that exploits only vision sensors, which are very versatile and minimally invasive. Using a visual sensor network and the proposed tracking approach we are able to know and track the position of every bus in the exchange station and to send data to the planning station, which allocates slots for other busses and manages public information. Preliminary results are promising and show the feasibility of the proposed method, so that future research work is directed towards a distributed implementation of the framework with stand-alone and embedded devices under the control of a supervisor.
Synthesis and characterization of rice husk silica, silica-carbon composite and H3PO4 activated silica (2008)

This paper discusses synthesis and characterization of (i) rice husk based nanosilica, (ii) nanosilica carbon composite granules and (iii) phosphoric acid activated ash silica. These have been produced by burning husk in air, charring husk in hydrogen and activating husk silica with H3PO4 respectively. X-ray diffraction studies of these products reveal increasing peak width (amorphosity) with decreasing burning temperature. The activated rice husk silica transforms to crystalline product when burnt above 1000 ºC. The variation of surface area and pore volume with burning temperature show different behavior for air fired and hydrogen charred products. Activation energy associated with change in surface area for air fired and hydrogen charred samples have also been studied. Rate of variation in surface area with temperature indicate different trend. The validations of these products have been evaluated by decolorizing capacity of standard molasses and iodine solution. The adsorptive powers of these products have been found to be highest for activated silica and lowest for hydrogenated ash.
Internet Surveillance: Content Analysis and Monitoring of Product-specific Internet Prescription Opioid Abuse-related Postings (2007)

These results suggest that a systematic approach to postmarketing surveillance of Internet chatter related to pharmaceutical products is feasible and yields reliable information about the quantity of discussion of specific products and qualitative information regarding the nature of the discussions. Kadian was associated with fewer Internet mentions than either OxyContin or Vicodin. This investigation stands as a first attempt to establish systematic methods for conducting Internet surveillance.
CD8+ T Cells Are Required for Primary Immunity in C57BL/6 Mice Following Low-Dose, Intradermal Challenge with <i>Leishmania major</i> (2002)

Standard murine models of cutaneous leishmaniasis, involving s.c. inoculation of large numbers of Leishmania major promastigotes, have not supported an essential role for CD8(+) T cells in the control of primary infection. Recently, a L. major model combining two main features of natural transmission, low parasite dose and inoculation into a dermal site, has been established in resistant C57BL/6 mice. In the present studies, C57BL/6 mice with CD8(+) T cell deficiencies, including CD8(-/-) and CD8-depleted mice, failed to control the growth of L. major following inoculation of 100 metacyclic promastigotes into the ear dermis. The resulting dermal pathology was minor and delayed. Lesion formation in wild-type mice was coincident with the killing of parasites in the inoculation site. Both events were associated with the accumulation of CD8(+) T lymphocytes in the skin and with the capacity of CD8(+) T cells recovered from draining lymph nodes or infected dermis to release IFN-gamma following coculture with infected dendritic cells. Reconstitution of resistance to L. major in RAG(-/-) mice using T cells from naive donors was optimal when both CD4(+) and CD8(+) T cells were transferred. Primed CD8(+) T lymphocytes obtained from C57BL/6 mice during the acute stage of infection were able to mediate both pathology and immunity when transferred alone. The low dose, intradermal challenge model reveals that CD8(+) T cells play an essential role in both pathogenesis of and immunity to primary infection with L. major in the skin.
Proteoglycans from Bovine Proximal Humeral Articular Cartilage (1973)

Abstract To provide methods applicable to the study of human articular cartilage, we have studied the extraction, fractionation, and physical characterization of proteoglycans from bovine articular cartilage. Two dissociative solvents, MgCl2 and GuHCl, differ sharply in the amount of the proteoglycan extracted from articular cartilage and the macromolecular species present in the initially extracted crude proteoglycan. PG(MgCl2), the crude proteoglycan extracted with 3 m MgCl2, is obtained in a yield of 0.16 g per g of dry cartilage, and accounts for 50% of the uronate and 23% of the hexose of the whole cartilage. PG(GuHCl), the crude proteoglycan extracted with 4 m GuHCl, is obtained in a yield of 0.26 g per g of dry cartilage, and accounts for 81% of the uronate and 61% of the hexose of the whole cartilage. On analytical ultracentrifugation in associative solvents, PG(MgCl2) shows three components: a 4 S protein, a 16 S proteoglycan species, and a 60 to 70 S proteoglycan aggregate. Equilibrium density gradient centrifugation of PG(MgCl2) under associative conditions in 4 m CsCl results in a sharp separation of the 4 S protein into the top sixth of the gradient, and of the 16 S species and 70 S aggregate into the bottom sixth of the gradient. On analytical ultracentrifugation in associative solvents, PG(GuHCl) shows a 4 S protein, a 16 S proteoglycan species, and a 56 S proteoglycan aggregate. The proteoglycan aggregate in either PG(MgCl2) or PG(GuHCl) is completely and reversibly dissociable in either 3 m MgCl2 or 3 m GuHCl. However, while dissociation in 3 m MgCl2 yields the 16 S species, dissociation in 3 m GuHCl yields a 10.5 S proteoglycan subunit. The isolated 16 S proteoglycan species has an intrinsic viscosity of 184 ml per g, a partial specific volume of 0.594 ml per g, and a molecular weight of 1.6 x 106. PG(GuHCl) contains a high molecular weight complex, not present in PG(MgCl2). The complex differs from the 70 S proteoglycan aggregate in size, as indicated by its sedimentation properties; in composition, as indicated by its lower proteoglycan and higher protein and collagen contents; and, in the noncovalent bonds involved in its formation, as indicated by its dissociation in 3 m GuHCl but not in 3 m MgCl2. Analytical ultracentrifugation of the dissociated complex in 3 m GuHCl shows that a 2.7 S protein is a major component of the complex. None of the 2.7 S protein is detectable in preparations of PG(MgCl2) or of the 70 S aggregate. Two states of macromolecular organization of proteoglycans appear to exist in articular cartilage. The first, and lower level of organization is that of the 70 S proteoglycan aggregate. The second and higher level of organization is that of the complex formed by the noncovalent association of proteoglycans and collagen in the presence of the 2.7 S protein.

Contactless vector network analysis using diversity calibration with capacitive and inductive coupled probes (2007)

Abstract. Contactless vector network analysis based on a diversity calibration is investigated for the measurement of embedded devices in planar circuits. Conventional contactless measurement systems based on two probes for each measurement port have the disadvantage that the signal-to-noise system dynamics strongly depends on the distance between the contactless probes. In order to avoid a decrease in system dynamics a diversity based measurement system is presented. The measurement setup uses one inductive and two capacitive probes. As an inductive probe a half magnetic loop in combination with a broadband balun is introduced. In order to eliminate systematic errors from the measurement results a diversity calibration algorithm is presented. Simulation and measurement results for a one-port configuration are shown.
A network structure approach to blind source separation using second order cyclic statistics (2002)

This paper addresses the problem of blind separation of cyclostationary sources. By using the cyclostationarity property of the source signals, a new criterion based on second order cyclic statistics (SOCS) is established, from which a network structure (NS) approach for blind source separation is proposed. Because the use of SOCS, the new approach requires few data samples and no restrictions on the distributions of the source signals. Simulation results are given to demonstrate the effectiveness of this new approach.
Towards a microfluidic dispenser chip for printing of single cells (2011)

We present a microfluidic dispenser chip for printing of single-particles or cells onto a substrate. The dispenser chip, fabricated in silicon/glass technology features hydrodynamic flow focusing to transport single particles in a fluid channel and a drop-on-demand dispensing mechanism to eject single particles confined in a free flying droplet of about 200 pl volume. A computer vision-based approach is employed to detect single particles prior to dispensing. We have evaluated the system experimentally by successfully depositing single polystyrene-beads on glass slides with a yield of 92%.
Homogentisic acid is the product of MelA, which mediates melanogenesis in the marine bacterium Shewanella colwelliana D (1994)

Shewanella colwelliana D is a marine procaryote which produces a diffusible brown pigment that correlates with melA gene expression. Previously, melA had been cloned, sequenced, and expressed in Escherichia coli; however, the reaction product of MelA had not been identified. This report identifies that product as homogentisic acid, provides evidence that the pigment is homogentisic acid-melanin (pyomelanin), and suggests that MelA is p-hydroxyphenylpyruvate hydroxylase. This is the first report of pyomelanin in an obligate marine bacterium.
The complete sequence of human preprocalcitonin (1984)

DNA complementary to mRNA extracted from the thyroid glands of patients suffering from medullary carcinoma of the thyroid (MCT), a calcitonin-producing tumour, was inserted in the Pst site of pBR 322 by G-C tailing. The recombinant plasmids were used to transform Escherichia coli DP 50. Ampicillin-resistant clones were screened using a 32P-labelled cDNA to mRNA extracted from a case of MCT particularly rich in calcitonin (CT) mRNA. Positive clones were subsequently rescreened using a 32P poly(T) probe. Eighty clones were thus purified, and the inserts obtained by digestion with PstI were subjected to positive hybridization selection with subsequent translation in vitro. An insert stimulating synthesis of the protein and containing restriction sites compatible with the previously published complete sequence of calcitonin mRNA from rat was sequenced. This cDNA insert contained the entire coding region of 426 bp, 70 bp at the 5'-end, and 295 bp upstream from the poly(A) tail. The complete amino acid sequence of human preprocalcitonin could thus be deduced.

Cloning and Nucleotide Sequence Analysis of Human Embryonic ζ-Globin cDNA (1982)

Clones of human embryonic alpha-like zeta-globin cDNA were isolated, by detection using cross-hybridization to human alpha-globin cDNA probes, from a cDNA library derived from the mRNA of the human erythroleukemia cell line K562. Nucleotide sequence analysis of these cDNA clones revealed a coding sequence that corresponds perfectly to the independently derived amino acid sequence of the human zeta-globin chain. Comparison of the nucleotide sequence of human zeta-globin cDNA with that of human alpha-globin cDNA confirmed previous estimates of very distant evolutionary divergence between the human zeta- and alpha-globin genes. Nevertheless, the human zeta-globin cDNA sequence shares a remarkable similarity to that of the alpha-globin gene in its codon usage, high G + C base composition, and lack of bias against usage of CG dinucleotides.
Maintaining multiple sclerosis patients' quality of life (2017)

This paper presents a case study on how smart-home technology can improve the quality of life for multiple sclerosis patients by implementing personalized environment control assistance. We developed a prototype that allows users with diminished motoric skills to use voice recognition software on a smartphone to control a house's front door, lights, telephone, TV and PC. We focused on affordable hardware and open-source software to maximize adaptability and extensibility, which is required for individual solutions. The development followed a user-centric design process, where a group of 10 multiple sclerosis patients participated in workshops to assess their requirements and evaluate the usability of the implemented prototype.
Probabilistic object tracking using multiple features (2004)

We present a generic tracker which can handle a variety of different objects. For this purpose, groups of low-level features like interest points, edges, homogeneous and textured regions, are combined on a flexible and opportunistic basis. They sufficiently characterize an object and allow robust tracking as they are complementary sources of information which describe both the shape and the appearance of an object. These low-level features are integrated into a particle filter framework as this has proven very successful for non-linear and non-Gaussian estimation problems. We concentrate on rigid objects under affine transformations. Results on real-world scenes demonstrate the performance of the proposed tracker.
Photochemical treatment of plasma with amotosalen and long‐wavelength ultraviolet light inactivates pathogens while retaining coagulation function (2006)

PCT of plasma inactivated high levels of a wide range of pathogens while maintaining adequate coagulation function. PCT has the potential to reduce the risk of transfusion-transmitted diseases in patients requiring plasma transfusion support.
A comparative study of nucleation parameterizations: 2. Three‐dimensional model application and evaluation (2010)

Following the examination and evaluation of 12 nucleation parameterizations presented in part 1, 11 of them representing binary, ternary, kinetic, and cluster‐activated nucleation theories are evaluated in the U.S. Environmental Protection Agency Community Multiscale Air Quality (CMAQ) modeling system version 4.4. The 12–28 June 1999 Southern Oxidants Study episode is selected as a testbed to evaluate simulated particulate matter (PM) number and size predictions of CMAQ with different nucleation parameterizations. The evaluation shows that simulated domain‐wide maximum PM 2.5 number concentrations with different nucleation parameterizations can vary by 3 orders of magnitude. All parameterizations overpredict (by a factor of 1.4 to 1.7) the total number concentrations of accumulation‐mode PM and significantly underpredict (by factors of 1.3 to 65.7) those of Aitken‐mode PM, resulting in a net underprediction (by factors of 1.3 to 13.7) of the total number concentrations of PM 2.5 under a polluted urban environment at a downtown station in Atlanta. The predicted number concentrations for Aitken‐mode PM at this site can vary by up to 3 orders of magnitude, and those for accumulation‐mode PM can vary by up to a factor of 3.2, with the best predictions by the power law of Sihto et al. (2006) (NMB of −31.7%) and the worst predictions by the ternary nucleation parameterization of Merikanto et al. (2007) (NMB of −93.1%). The ternary nucleation parameterization of Napari et al. (2002) gives relatively good agreement with observations but for a wrong reason. The power law of Kuang et al. (2008) and the binary nucleation parameterization of Harrington and Kreidenweis (1998) give better agreement than the remaining parameterizations. All the parameterizations fail to reproduce the observed temporal variations of PM number, volume, and surface area concentrations. The significant variation in the performance of these parameterizations is caused by their different theoretical bases, formulations, and dependence on temperature, relative humidity, and the ambient levels of H 2 SO 4 and NH 3 . The controlling processes are different for PM number, mass, and surface areas. At urban/rural locations, some PM processes (e.g., homogeneous nucleation) and/or vertical transport may dominate the production of PM 2.5 number, and emissions, or PM processes, or vertical transport or their combinations may dominate the production of PM 2.5 mass and surface area. Dry deposition or some PM processes such as coagulation may dominate PM 2.5 number loss, and horizontal and vertical transport, and cloud processes (e.g., cloud scavenging and wet deposition) may dominate the loss of PM 2.5 mass and surface area concentrations. Sensitivity simulations show that the PM number and size distribution predictions are most sensitive to prescribed emission fractions of Aitken and accumulation‐mode PM and the assumed initial PM size distribution, in addition to different nucleation parameterizations.
FIELD RESULTS USING POLYACRYLAMIDE TO MANAGE FURROW EROSION AND INFILTRATION (1994)

Furrow irrigation-induced soil erosion is a serious threat to sustainable irrigated agriculture globally. Recent field studies have demonstrated that small concentrations of polymers dissolved in irrigation water appreciably reduce soil loss from irrigated furrows and increase net infiltration (total inflow - total outflow). This paper summarizes polymer-related field studies conducted in Idaho on highly erodible silt loam soils (Durixerollic Calciorthids, Xerollic Haplargids, Haploxerollic Durargids). A range of furrow lengths (163–264 m), slopes (0.5–7%), and inflows (15–38 L min−1) were included in the studies. A moderate-charge-density anionic polyacrylamide (PAM), highly effective for controlling furrow sediment losses, was employed in the field trials. Treatment efficacy depended primarily on application rate, PAM concentration in irrigation water, duration of furrow exposure, and inflow rate. Nontreated furrow soil loss in 75% of the irrigations exceeded soil loss tolerance (T) for these soils, whereas only 13% of the PAM-treated irrigations exceeded T. Those treatments that applied at least 0.7 kg ha−1 PAM (mean, 1.3 kg ha−1) reduced furrow sediment loss by 94% (range: 80–99%) and increased not infiltration by 15% (range: −8–57%). One of the most effective treatments applied PAM at 10 g m3 in irrigation inflows during the furrow advance period. This initial high-load treatment was nearly twice as effective as a continuous 0.25 g m−3 PAM application on these soils when slopes were 1–2%. The initial high-load treatment protected furrows with slopes ranging from 0.5 to 3.5%. PAM reduced total phosphorus (84% of control value), nitrate (83%), biochemical oxygen demand (72%), and sediment (57%) in treated runoff water
Fast fault section estimation in distribution substations using matrix-based cause-effect networks (2001)

A new method for estimating fault sections in power substations is proposed. In this paper the knowledge representation and inference procedures based on the cause-effect networks (CE-Nets) and rule matrix transformation techniques are presented. The matrix based inference procedures are proposed to estimate the possible fault sections through simple matrix operations by transforming the established CE-Nets into matrix forms. The method is superior to existing production systems in the inference speed and the process of implementation. By testing on a typical Taiwan Power Company's (Taipower) secondary substation, the experimental results show that the effectiveness of the proposed method even for the fault domains involving multiple faults and failure operations of protective devices. Moreover, it is easy to implement and transplant into different substations.
An infrastructure for collaborative teleteaching (2002)

Teleteaching is a typical application of collaborative environments. As a basis for implementing teleteaching scenarios, sophisticated distributed software platforms and advanced networking facilities are required. This paper presents such an infrastructure and discusses recent results with its experimental use. In addition to key technological issues such as multimedia information management and distribution, important other aspects of collaborative work are discussed in this context; examples are user interaction, content provision, and acceptance of given solutions. Evaluating the experiences with this collaborative environment, an extended, Java-based environment for advanced teleteaching scenarios has been designed. The paper discusses its architecture and components and gives an outlook to future implementation and evaluation tasks.
