Cross-Linking-Induced Permanently Perpendicular Helix Orientation in Surface-Grafted Polyglutamate Films (2007)

Using a chemical cross-linking procedure, surface-grafted polyglutamate films with a permanently perpendicular helix orientation were prepared. A surface-grafted alpha-helical polyglutamate film containing polymerizable side groups was synthesized by ring-opening terpolymerization of 50 molar% gamma-methyl-L-glutamate N-carboxyanhydride (NCA), 30% gamma-stearyl-L-glutamate NCA and 20% gamma-4-vinylbenzyl-L-glutamate NCA initiated from a silicon substrate functionalized with primary amino groups. The average tilt angle of the end-grafted helices in this film is approximately 66 degrees , indicating a nearly parallel helix orientation with respect to the substrate surface. After swelling of the grafted terpolyglutamate film in stearyl methacrylate and subsequent radical cross-linking, the average helix tilt angle decreases to about 11 degrees, indicating an almost perpendicular helix orientation. The film thickness increases accordingly from 151 A before to approximately 390 A after cross-linking. Extensive solvent treatment of the cross-linked film shows that the perpendicular helix orientation is permanent.
Effects of drawing tension on the photosensitivity of Sn–Ge- and B–Ge-codoped core fibers (1998)

The influence of drawing tension on the formation of Bragg gratings in B-Ge- and Sn-Ge-codoped core fibers is investigated by transmission and stress measurements. With increasing drawing tension, the axial stress is reduced in the B-Ge-codoped core but increased in the Sn-Ge-codoped core. A higher drawing tension leads to a photosensitivity enhancement and an increase of the core stress during the grating formation in B-Ge-codoped fibers. For Sn-Ge-codoped fibers, increased drawing tension results in an UV-induced stress decrease accompanied by a reduction of the photosensitivity. The results are discussed on the basis of an UV-induced compaction of the core network.
Broad-band beamforming and the generalized sidelobe canceller (1986)

This correspondence identifies general conditions under which the generalized sidelobe canceller (GSC) structure implements a linearly constrained minimum variance (LCMV) broad-band beam-former. In previously published work, conditions have been presented for the case in which the linear constraint is restricted to fixed gain in the steer direction. Here, that work is extended to include general linear constraints. A geometric interpretation is presented to provide insight into the relationship between the GSC structure and LCMV beamformers, and several recent developments in broad-band beam-forming are reviewed and related to the GSC structure.
Real-Space Observation of Dipolar Antiferromagnetism in Magnetic Nanowires by Spin-Polarized Scanning Tunneling Spectroscopy (2000)

We have performed spin-polarized scanning tunneling spectroscopy of dipolar antiferromagnetically coupled Fe nanowires with a height of two atomic layers and an average separation of 8 nm grown on stepped W(110). Domain walls within the nanowires exhibit a significantly reduced width when pinned at structural constrictions. The lateral spin reorientation in the direction perpendicular to the wires has been studied with subnanometer spatial resolution. It is found that the spin canting in the Fe nanowires monotonously increases towards the step edges.
Nerve Injury Associated with Anesthesia  (1999)

New strategies for prevention of nerve damage cannot be recommended at this time because the mechanism for most injuries, particularly those of the ulnar nerve, is not apparent.
Flexible architecture for CMOS sensor interfaces (2003)

The authors describe the design and implementation of an interface circuit for CMOS sensor systems. The objective is to provide a microprocessor compatible sensor on a single chip. A system architecture that minimizes analog content and where most of the signal processing is done digitally is illustrated. Great flexibility and robustness were achieved by the use of a sigma-delta modulator and by introducing the sensor element directly in the modulator's first stage. Example applications for a magnetic sensor and a humidity sensor are presented.< <ETX xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">></ETX>
A Vector-based, Multidimensional Scanpath Similarity Measure (2010)

Figure 1: Are these scanpaths similar? Scanpaths from two participants looking at the same stimulus. A great need exists in many fields of eye-tracking research for a robust and general method for scanpath comparisons. Current mea-sures either quantize scanpaths in space (string editing measures like the Levenshtein distance) or in time (measures based on atten-tion maps). This paper proposes a new pairwise scanpath similarity measure. Unlike previous measures that either use AOI sequences or forgo temporal order, the new measure defines scanpaths as a series of geometric vectors and compares temporally aligned scan-paths across several dimensions: shape, fixation position, length, direction, and fixation duration. This approach offers more multi-faceted insights to how similar two scanpaths are. Eight fictitious scanpath pairs are tested to elucidate the strengths of the new mea-sure, both in itself and compared to two of the currently most pop-ular measures- the Levenshtein distance and attention map corre-lation.

An appraisal of statistical procedures used in derivation of reference intervals (2010)

When conducting studies to derive reference intervals (RIs), various statistical procedures are commonly applied at each step, from the planning stages to final computation of RIs. Determination of the necessary sample size is an important consideration, and evaluation of at least 400 individuals in each subgroup has been recommended to establish reliable common RIs in multicenter studies. Multiple regression analysis allows identification of the most important factors contributing to variation in test results, while accounting for possible confounding relationships among these factors. Of the various approaches proposed for judging the necessity of partitioning reference values, nested analysis of variance (ANOVA) is the likely method of choice owing to its ability to handle multiple groups and being able to adjust for multiple factors. Box-Cox power transformation often has been used to transform data to a Gaussian distribution for parametric computation of RIs. However, this transformation occasionally fails. Therefore, the non-parametric method based on determination of the 2.5 and 97.5 percentiles following sorting of the data, has been recommended for general use. The performance of the Box-Cox transformation can be improved by introducing an additional parameter representing the origin of transformation. In simulations, the confidence intervals (CIs) of reference limits (RLs) calculated by the parametric method were narrower than those calculated by the non-parametric approach. However, the margin of difference was rather small owing to additional variability in parametrically-determined RLs introduced by estimation of parameters for the Box-Cox transformation. The parametric calculation method may have an advantage over the non-parametric method in allowing identification and exclusion of extreme values during RI computation.
Cholesteryl ester transfer protein (CETP) mRNA abundance in human adipose tissue: relationship to cell size and membrane cholesterol content. (1995)

Cholesteryl ester transfer protein (CETP) has a well-defined role in plasma neutral lipid transport. CETP synthesized by human adipose tissue may contribute to the plasma CETP pool. CETP mRNA abundance increases in subcutaneous adipose tissue in response to cholesterol feeding and we have hypothesized that CETP gene expression is regulated by a specific pool of cellular sterol. In the present study, we have quantified CETP mRNA levels in subcutaneous adipose tissue of 10 female subjects using a solution hybridization RNase protection assay. Particulate (membrane cholesterol) and lipid droplet cholesterol (core cholesterol) were determined by gas chromatography. CETP mRNA abundance in these adipose tissue specimens correlated significantly with membrane cholesterol expressed as a fraction of membrane protein (r = 0.67, P = 0.031). There was also a linear relationship between CETP mRNA abundance and membrane cholesterol to core triglyceride ratio (r = 0.77, P = 0.009) and a strong correlation between the percentage of cellular cholesterol in the membrane fraction (ratio of membrane to core cholesterol) and CETP mRNA abundance (r = 0.91, P = 0.0002). In contrast, there was a negative relationship between each of lipid droplet cholesterol and triglyceride and CETP mRNA levels. Human adipose tissue maintained in organ culture for several days was shown to secrete CETP into the culture medium. Incubation with cholesterol-rich chylomicron remnants elicited a dose-dependent increase in both membrane and core cholesterol and a concomitant increase in the level of CETP mRNA. These studies demonstrate that adipose tissue CETP mRNA abundance is a function of membrane cholesterol concentration rather than lipid droplet cholesterol and that CETP mRNA increases with adipocyte cholesterol enrichment via chylomicron remnants. CETP gene expression is highest in small lipid-poor adipocytes, suggesting that CETP synthesized and secreted by adipocytes may have a role in promoting cellular cholesterol accumulation.
Effect of Variation in Test Methods on Performance of Ultraviolet-C Radiation Room Decontamination (2016)

Variation in test methods can significantly impact measured reductions in pathogens by UV-C devices during experimental testing. Our findings highlight the need for standardized laboratory methods for testing the efficacy of UV-C devices and for evaluations of the efficacy of short UV-C exposure times in real-world settings.
Mechatronics for a new robot generation (1996)

The paper outlines the DLR's mechatronic developments in the robotics area over the last five years. They aim at designing a new multisensory, modularly configurable lightweight robot generation in a unified and integral way. A first step in this direction has been the development of a complex multisensory gripper. It turned out to be a key element in ROTEX, the first real robot in space that flew with shuttle Columbia in early 1993. Sensors and actuators in DLR's new ultra-lightweight robot show up miniaturized integration of mechanics, electronics, and microprocessor control. Joint torque control based on inductive sensing is realized in the compact, highly reducing rotational gearings. With optimized carbon-fiber grid structures, optical high-speed information transfer between the joints and all power and signal electronics integrated into the arm, a new extremely lightweight type of robot arises. Joint control concepts are outlined and a 7 degree-of-freedom version of such a lightweight arm is described. The paper also outlines the concept of the artificial muscle and its use in the fingers of a new modular articulated robot hand. Sensor-based man-machine interfaces and automatic camera guidance by robots in minimal invasive surgery are other topics covered in the paper.
Reversal of Optic Disc Topography in Patients with Glaucomatocyclitic Crisis After Remission of Attack (1998)

In patients experiencing glaucomatocyclitic crisis, reversal of optic disc topography were associated with reduction of IOP.
Single Image Action Recognition by Predicting Space-Time Saliency (2017)

We propose a novel approach based on deep Convolutional Neural Networks (CNN) to recognize human actions in still images by predicting the future motion, and detecting the shape and location of the salient parts of the image. We make the following major contributions to this important area of research: (i) We use the predicted future motion in the static image (Walker et al., 2015) as a means of compensating for the missing temporal information, while using the saliency map to represent the the spatial information in the form of location and shape of what is predicted as significant. (ii) We cast action classification in static images as a domain adaptation problem by transfer learning. We first map the input static image to a new domain that we refer to as the Predicted Optical Flow-Saliency Map domain (POF-SM), and then fine-tune the layers of a deep CNN model trained on classifying the ImageNet dataset to perform action classification in the POF-SM domain. (iii) We tested our method on the popular Willow dataset. But unlike existing methods, we also tested on a more realistic and challenging dataset of over 2M still images that we collected and labeled by taking random frames from the UCF-101 video dataset. We call our dataset the UCF Still Image dataset or UCFSI-101 in short. Our results outperform the state of the art.
Maximizing the impact of power ICs via a time-to-market CAD driven power ASIC strategy (2003)

Great strides have been made in developing silicon processes that provide the benefits of high-level integration to power circuits. A recent example of such work at Harris Semiconductor has been the development of a power application-specific integrated circuit (PASIC) technology that allows integration on a single chip of a complete 1 MHz DC-DC converter. Despite such technological achievements, the marketplace further demands quick/low-risk design cycle times to capture opportunities before market windows close. It is also imperative to provide easy access to the technology for system-level designers, as opposed to traditional circuit designers, since they ultimately are knowledgeable and responsible for defining the function to be produced. The authors describe Harris's PASIC technology and demonstrate how computer-aided design (CAD) tools and concurrent engineering methods have been applied to achieve the above objective.< <ETX xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">></ETX>
Development of New Water Tree Suppressive XLPE Cable (1986)

With a view to develop a new water tree suppressive XLPE cable, the authors have investigated the effect of introducing polar groups into crosslinked polyethylene (XLPE) dielectrics. An aliphatic carboxylic acid derivative was found to be the best additive as a water tree suppressor. New cables insulated with XLPE dielectrics containing this aliphatic carboxylic acid derivative were developed. It was confirmed that the cables, having the same physical and electrical properties as those of conventional XLPE cables, showed an excellent water tree suppressive effect and long term performance.
Targeting Epigenetic Programs in MLL-Rearranged Leukemias (2011)

Rearrangements of the Mixed-Lineage Leukemia (MLL) gene are found in > 70% of infant leukemia, ~ 10% of adult acute myelogenous leukemia (AML), and many cases of secondary acute leukemias. The presence of an MLL rearrangement generally confers a poor prognosis. There are more than 60 known fusion partners of MLL having some correlation with disease phenotype and prognosis. The most common fusion proteins induce the inappropriate expression of homeotic (Hox) genes, which, during normal hematopoiesis, are maintained by wild-type MLL. MLL-rearranged leukemias display remarkable genomic stability, with very few gains or losses of chromosomal regions. This may be explained by recent studies suggesting that MLL-rearranged leukemias are largely driven by epigenetic dysregulation. Several epigenetic regulators that modify DNA or histones have been implicated in MLL-fusion driven leukemogenesis, including DNA methylation, histone acetylation, and histone methylation. The histone methyltransferase DOT1L has emerged as an important mediator of MLL-fusion-mediated leukemic transformation. The clinical development of targeted inhibitors of these epigenetic regulators may therefore hold promise for the treatment of MLL-rearranged leukemia.
Structural Decompositions for End-to-End Relighting. (2019)

Relighting is an essential step in realistically transferring objects from a captured image into another environment. For example, authentic telepresence in Augmented Reality requires faces to be displayed and relit consistent with the observer's scene lighting. We investigate end-to-end deep learning architectures that both de-light and relight an image of a human face. Our model decomposes the input image into intrinsic components according to a diffuse physics-based image formation model. We enable non-diffuse effects including cast shadows and specular highlights by predicting a residual correction to the diffuse render. To train and evaluate our model, we collected a portrait database of 21 subjects with various expressions and poses. Each sample is captured in a controlled light stage setup with 32 individual light sources. Our method creates precise and believable relighting results and generalizes to complex illumination conditions and challenging poses, including when the subject is not looking straight at the camera.
A Cubic Monoolein−Cytochrome <i>c</i>−Water Phase:  X-ray Diffraction, FT-IR, Differential Scanning Calorimetric, and Electrochemical Studies (1996)

Cytochrome c (cyt c) has been studied as an example of a peripheral membrane protein that forms a cubic phase with monooleoylglycerol (monoolein, MO) and aqueous solutions. The unit cell dimensions of the cubic phases (space group Pn3m) in relation to the composition of the aqueous solution and protein concentration were analyzed according to the concept of a lipid packing parameter in the bilayer. The interaction between cyt c and MO in the cubic phase was studied by FT-IR spectroscopy and differential scanning calorimetry (DSC). The FT-IR data indicated a somewhat higher conformational order of the MO acyl chain and structural rearrangements of the polar head-group region in the cubic MO−cyt c−H2O phase. These findings, together with the increase in unit cell dimension, suggested a decrease of the MO packing parameter upon protein incorporation. Furthermore, a competitive interaction between the protein and buffer ions at the lipid bilayer was observed. DSC measurements showed that incorporation of cyt c into the cubic MO−H2O phase resulted in a significant decrease in temperature during the phase transitions cubic → reversed hexagonal → reversed micellar, and the unfolding of the protein took place simultaneously with the first phase transition. Additionally, voltammetric and chronoamperometric studies of the direct redox conversions of cyt c at the 4,4‘-dithiodipyridine-modified gold electrode revealed that the mobility of the protein molecules within the cubic phase was highly restricted. Altogether, these findings indicate that nonelectrostatic interactions between peripheral proteins and lipid molecules in membranes might also play a role in regulating biological function.
Temperature dependence of the Urbach edge in GaAs (1995)

The temperature dependence of the optical-absorption edge (Urbach edge) of GaAs is measured in semi-insulating and n-type GaAs (n=2×1018 cm−3) over the temperature range from room temperature to 700 °C. Both the optical absorption and the temperature are measured using a diffuse reflectance technique. The characteristic energy of the exponential absorption edge is found to increase linearly with temperature, from 7.5 meV at room temperature to 12.4 meV at 700 °C, for semi-insulating GaAs. The temperature dependent part of the width of the Urbach edge for semi-insulating GaAs is six times smaller than predicted by the standard theory where the edge width is proportional to the phonon population.
35-dB gain Tm-doped ZBLYAN fiber amplifier operating at 1.65 μm (1996)

We demonstrate the first high gain rare-earth-doped fiber amplifier operating at 1.65 μm. It consists of ZBLYAN fiber with a Tm/sup 3+/-doped core and Tb/sup 3+/-doped cladding, pumped by 1.22 μm laser diodes. It is possible to achieve efficient amplification with Tm/sup 3+/ ions if their amplified spontaneous emission (ASE) in the 1.75 to 2.0 μm wavelength region is suppressed by doping Tb/sup 3+/ ions in the cladding. A two-stage-type fiber amplifier is constructed and a signal gain of 35 dB is achieved for a pump power of 140 mW. A gain over 25 dB is realized in the 1.65 μm to 1.67 μm wavelength region.
H method for solving 3D eddy current problems (1995)

A novel finite element model, which uses magnetic field intensity H as a state variable in the whole solution region of 3D eddy current problems, is presented. A surface integral on the interface, which leads to asymmetric equations in discretization, is considered in this formulation. The formulation uses consistently linear edge elements and flux continuity is ensured by imposing /spl nabla//spl middot/B=0 with the penalty method. Numerical results of the problem No. 3 of the Team Workshop are provided, showing the validity of the algorithm.
