Audio-Based Feedback Techniques for Teaching Touchscreen Gestures (2015)

While sighted users may learn to perform touchscreen gestures through observation (e.g., of other users or video tutorials), such mechanisms are inaccessible for users with visual impairments. As a result, learning to perform gestures without visual feedback can be challenging. We propose and evaluate two techniques to teach touchscreen gestures to users with visual impairments: (1) gesture sonification to generate sound based on finger touches, creating an audio representation of a gesture; and (2) corrective verbal feedback that combined automatic analysis of the user's drawn gesture with speech feedback. To refine and evaluate the techniques, we conducted three controlled laboratory studies. The first study, with 12 sighted participants, compared parameters for sonifying gestures in an eyes-free scenario. We identified pitch+stereo panning as the best combination. In the second study, ten blind and low-vision participants completed gesture replication tasks for single-stroke, multistroke, and multitouch gestures using the gesture sonification feedback. We found that multistroke gestures were more difficult to understand in sonification, but that playing each finger sound serially may improve understanding. In the third study, six blind and low-vision participants completed gesture replication tasks with both the sonification and corrective verbal feedback techniques. Subjective data and preliminary performance findings indicated that the techniques offer complementary advantages: although verbal feedback was preferred overall primarily due to the precision of its instructions, almost all participants appreciated the sonification for certain situations (e.g., to convey speed). This article extends our previous publication on gesture sonification by extending these techniques to multistroke and multitouch gestures. These findings provide a foundation for nonvisual training systems for touchscreen gestures.
Anti-Inflammatory Principles of Cultivated Pycnoporus Sanguineus (2010)

Pycnoporus sanguineus is a parasitic fungus found on dead broadleaf trees and used as a nutraceuticals and functional food. LPS-induced NO production in a mouse microglial cell line, BV-2 cells was used as inflammatory model to screen neuro-protective compounds from the cultivated mycelia of P. sanguineus. Bioassay-guided fractionation was led to the isolation of four ergostane skeleton type steroids, including ergosta-7,22-dien-3β-ol (1), 3β,5α-dihydroxyergosta-7,22-dien-6-one (2), 3β,5α,9α-trihydroxy-ergosta-7,22-dien-6-one (3), and 3β,5α,6α-trihydroxy-ergosta-7,22-diene (4) from mycelia of cultivated P. sanguineus. Among that, compounds 2, 3, and 4 were newly isolated in this species. Compound 1 showed significantly inhibition of lipopolysaccharide (LPS)-induced nitric oxide (NO) production in BV-2 cells, at a concentration of 15 μM in the value of 43.5%.
Abnormal Glucose Tolerance and Hypertension (1990)

To quantify the association of abnormal glucose tolerance with hypertension and postural hypotension, 2480 men and women aged 50-89 yr from a defined population were evaluated by oral glucose tolerance and measurements of supine, seated, and standing blood pressure. In both sexes, adults with impaired glucose tolerance or non-insulin-dependent diabetes mellitus (NIDDM) had increased mean blood pressure compared with those with normal glucose tolerance. These differences were both statistically (P less than 0.05) and clinically (3-12 mmHg) significant and were independent of age, obesity, and the use of antihypertensive medication. Age-adjusted rates of systolic hypertension and isolated systolic hypertension were also higher in subjects with impaired glucose tolerance or NIDDM compared with those with normal glucose tolerance. Diastolic blood pressures and rates of diastolic hypertension were minimally higher in adults with impaired glucose tolerance and NIDDM. In both sexes, systolic blood pressure correlated significantly with fasting plasma glucose and 2-h postchallenge plasma glucose even after adjustment for age and obesity. Postural hypotension occurred in 7% of all subjects and did not vary significantly according to glucose tolerance.
Serological Differentiation of Infections with Dengue Virus Serotypes 1 to 4 by Using Recombinant Antigens (2002)

The B domains of dengue virus serotypes 1 to 4 were expressed in Escherichia coli. The purified proteins were applied to immunoblot strips to detect serotype-specific antibodies in paired serum samples from 41 patients with primary and secondary dengue infections. A close correlation between the results obtained with the immunoblot strips and by type-specific reverse transcription-PCR (T. Laue, P. Emmerich, and H. Schmitz, J. Clin. Microbiol. 37:2543-2547, 1999) was observed.
The three-dimensional structure of confined swirling flows with vortex breakdown (2001)

In a recent experimental study, Spohn, Mory & Hopfinger (1998) investigated in detail the flow in a closed cylindrical container with a rotating bottom for Reynolds numbers in the steady and unsteady regimes. Their visualization photographs revealed that the stationary vortex breakdown bubbles, which form along the container axis within a range of governing parameters, are open, with inflow and outflow, and asymmetric at their downstream end. For Reynolds numbers within the unsteady regime, visualizations of the limiting streamlines on the cylindrical wall showed that the Stewartson layer separates asymmetrically along stationary spiral convergence lines that form below the top cover. We study numerically the container flow, by solving the unsteady, three-dimensional Navier–Stokes equations, in order to clarify the origin and elucidate the underlying physics of these complex, three-dimensional flow features. The stationary vortex breakdown bubbles we simulate exhibit all the asymmetries observed in the laboratory. By analysing the Lagrangian characteristics of the calculated flow fields, we explain the origin of these asymmetries, clarify the experimentally documented filling and emptying mechanisms, and show that the flow in the interior of stationary vortex breakdown bubbles exhibits chaotic particle paths. We also show that the spiral separation lines observed by Spohn et al . (1998) inside the Stewartson layer at high Reynolds numbers are due to the growth of pairs of counter-rotating, spiral vortices and the interaction of these vortices with the stationary-cover boundary layer.
Claudin 4 Protein Expression in Primary and Metastatic Pancreatic Cancer Support for Use as a Therapeutic Target (2004)

We performed a comprehensive immunohistochemical evaluation of claudin 4 protein expression in paraffin-embedded tissue samples from 72 patients with primary infiltrating pancreatic cancer, 38 patients with metastatic pancreatic cancer, and a panel of normal control tissue samples from various organs. In 11 samples of primary infiltrating pancreatic cancer, foci of pancreatic intraepithelial neoplasia (PanIN) were present and also were analyzed for claudin 4 protein expression. Intense positive claudin 4 immunolabeling was noted within virtually all primary (71/72 [99%]) and metastatic (49/49 [100%]) pancreatic cancer tissue samples analyzed and in 10 of 11 samples of PanIN. In all cases, immunolabeling was noted in a membranous distribution. Claudin 4 protein also was detectable in normal breast, prostate, bladder, and gastrointestinal mucosa, although expression was substantially less intense than that seen in pancreatic cancer tissue samples. Our findings support the use of claudin 4 as a target for novel therapeutics or radioimaging of infiltrating pancreatic cancer. Furthermore, the finding of claudin 4 overexpression within pancreatic intraepithelial neoplasia, the precursor lesion of pancreatic cancer, suggests a potential benefit of imaging claudin 4 before the development of an invasive carcinoma.

Overview on AON Design (2012)

Antisense-mediated exon skipping is an attractive tool to study gene function as well as a promising therapeutic application for a number of diseases. In order for antisense oligonucleotides (AONs) to induce effective exon skipping during pre-mRNA splicing, they have to fulfill certain criteria. These include resistance against endo- and exonucleases and RNase H-induced cleavage and suitable thermodynamic properties. Furthermore, the AON-target sequence needs to be accessible and should contain sequence motives that are essential for proper inclusion of the exon into the mRNA. For most genes, only a few AONs have been designed, with the exception of the DMD gene, for which over 400 AONs targeting the majority of DMD exons have been reported. This allows retrospective analysis of effective and ineffective AONs to obtain guidelines to optimize future AON design.
Reliable computation of the points of intersection of $n$ spheres in $R^n$ (2000)

The problem of determining the points of intersection of n spheres in R n has many applications. Examples in 3-D include problems in navigation, in positioning of specific atoms in crystal structures, in reconstructing torso geometries in experimental cardiology, in the `Pentacle Problem,' and in many other problems of distance geometry. The problem is easily formulated as a system of n nonlinear equations in the coordinates of the unknown point(s) of intersection and it is of interest to determine an efficient and reliable method of solution. It is shown that apart from a few square roots the problem is usually easily and robustly solved without iteration by employing standard techniques from linear algebra. In some applications, however, the radii of the spheres may not be known accurately and this can lead to difficulties, particularly when the required point is close to lying in the affine subspace defined by the n centres of the spheres. In such cases it is more appropriate to formulate a nonlinear least squares problem in order to identify a `best approximate solution.' The special structure of this nonlinear least squares problem allows a solution to be calculated through an efficient safeguarded Newton iteration.

A general model and calibration method for spherical stereoscopic vision (2012)

In geometric calibration of stereoscopic cameras the object is to determine a set of parameters which describe the mapping from 3D reference coordinates to 2D image coordinates, and indicate the geometric relationships between the cameras. While various methods for stereo cameras with ordinary lenses can be found from the literature, stereoscopic vision with extremely wide angle lenses has been much less discussed. Spherical stereoscopic vision is more and more convenient in computer vision applications. However, its use for 3D measurement purposes is limited by the lack of an accurate, general, and easy-to-use calibration procedure. Hence, we present a geometric model for spherical stereoscopic vision equipped by extremely wide angle lenses. Then, a corresponding generic mathematical model is built. Method for calibration the parameters of the mathematical model is proposed. This paper shows practical results from the calibration of two high quality panomorph lenses mounted on cameras with 2048x1536 resolutions. Here, the stereoscopic vision system is flexible, the position and orientation of the cameras can be adjusted randomly. The calibration results include interior orientation, exterior orientation and the geometric relationships between the two cameras. The achieved level of calibration accuracy is very satisfying.
Interactive Self-Healing for Black-Box Components in Distributed Embedded Environments (2007)

Abstract. As self-management features of computer systems depend on self-knowledge we have to cope with the issue that most large systems are not entirely known to the self-management software. Especially when system parts are supplied by external companies which want to preserve their intellectual property we have to cope with black-box components. This paper presents a novel approach for self-healing in distributed embedded systems containing black-box application software. The interactive self-healing process is based on well defined system knowledge and enables the construction of a functional dependency graph which serves as basis for rule-based root cause analysis and self-healing. 1

A semi-empirical model for electroabsorption in GaAs/AlGaAs multiple quantum well modulator structures (1990)

A semiempirical model for electroabsorption in GaAs/AlGaAs quantum wells that is simple and has sufficient accuracy to make it suitable as a fast design tool for multiple quantum well (MQW) optical modulators is proposed. The model is based on a higher-order perturbation approach which includes all bound solutions of the unperturbed Hamiltonian. To complete the model, semiempirical relationships are set up for both the zero-field absorption peak and the half-width at half-maximum (HWHM) values of the heavy-hole exciton. Comparison with extensive experimental data shows a remarkable agreement for a range of wells between 5 and 20 nm and for photon energies on the long wavelength side of the absorption peak. These wavelength and well-size ranges coincide with those needed for practical design.< <ETX xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">></ETX>

High-Rate Glass Etching Process for Transferring Polycrystalline Silicon Thin-Film Transistors to Flexible Substrates (2005)

We report on a process technology that makes possible the transfer of polycrystalline silicon thin-film transistor (poly-Si TFT) arrays from an original rigid glass substrate to another flexible plastic substrate. The transfer technology is characterized by its high-rate glass etching process, using a newly developed apparatus. After a description of the transfer sequence free from adhesive contamination, we present experimental observations for high-rate glass etching in hydrofluoric (HF) and hydrochloric (HCl) acid solution mixtures. The etching apparatus provides jets of the solution mixtures to the glass surface in order to achieve good circulation of the solutions in the bath, as well as to remove etch products effectively from the surface. We successfully achieved etch rates as high as 6 /spl mu/m/min with the etched surfaces almost as smooth as the original glass. In order to gain insight into the chemical mechanism of the etching, we developed a simplified kinetic etching model based on a Langmuir isotherm. The model and experimental etch-rate data are generally in good agreement, indicating that the basic modeling approach captures much of the essential chemistry for the high-rate glass etching. The transfer technology allows us to obtain TFT flexible substrates with good electrical characteristics and flexibility even after an annealing process at as high as 150/spl deg/C. These results demonstrate that the transfer technology is a promising candidate for achieving entirely new lightweight electronic devices such as flexible displays and radio frequency identification tags based on TFT flexible substrates.
Pattern Translation Tool for Post-Silicon ASIC Testing (2018)

Post-Silicon design validation of digital ASICs on Automated-Test-Equipment (ATE) require test vectors for chip functional verification. These test vectors are generated by running post-layout design simulations. Integrated Circuit (IC) Design tools let these simulation waveforms dumped in industry popular formats like Value Change Dump (VCD)/ Extended Value Change Dump (EVCD) and Standard Test Interface Language (STIL). Once a chip gets fabricated these pattern files are used by IC test engineer to test the chip for intended functionality using VLSI testers. Not all these test pattern file formats are directly portable on all testers. Some VLSI testers need test vectors in STIL and others only accept tester specific compressed pattern formats. Only few test pattern conversion utilities are available commercially in the market. Making test pattern conversion process easy can save test engineers efforts and faster design-to-test cycle. This paper describes development of one such pattern conversion software to make test pattern conversion process fast and efficient. We have named this tool as PATCON; an acronym for Pattern Conversion.

The transistors are then laterally scaled from a gate length of 25 nm to 20, 15, 10 and 5 nm monitoring the average electron velocity, energy, and sheet density along the channel at a supply voltage of 1.0 V. A degradation of the injection velocity with the scaling of a gate/channel length is observed. While we have found a decrease in the overall electron velocity profile along the Si channel for gate lengths smaller than 10 nm and a decrease in the injection velocity from a gate length of 20 nm, the increase in the intrinsic drain current in the scaling process is continuous thanks to the increasing velocity at the drain side. However, the velocity in the InGaAs channel MOSFETs increases steadily during the scaling but the increase in the intrinsic drain current is less pronounced. This is the result of a source starvation, due to a low density of states in III-V semiconductors, which cannot provide a large enough electron sheet density in the channel. This effect is partially mitigated by the enhancement of density of states as a proportion of electrons in the source/drain transfers to upper valleys with a larger electron effective mass.
A Low-cost Fingerprint Positioning System in Cellular Networks (2007)

An ultimate aim of mobile positioning research is to find a method providing high estimation accuracy to the user within minimum delay and at minimum cost. Conventional location techniques based on trilateration and triangulation rely on line-of-sight path between the base station antenna and the mobile unit. In densely built urban areas, this assumption is rarely valid. This fact degrades the location performance of the conventional techniques and motivates the need for development of more accurate technique suited for these areas. Positioning system developed in this research is divided into three sub-systems. The first sub-system solves the problems related to fingerprint localization and involves neural network as key element of the positioning algorithm. The postprocessing tasks which include tracking and map-matching are performed in the second and third sub-systems respectively.
