Cover Image: Foreground image taken from Tongzhong Ju et al., (pp. 618–631): IgA1 has normalO-glycans with a core 1 O-glycan decorated with sialic acids (purple diamonds) in either mono- or disiaylated structures. But in IgA1 from IgA nephropathy (IgAN) patients it is proposed that Tn and STn antigens lacking the core 1 O-glycan accumulate and contribute to IgAN. IgAN is the most common glomerulonephritis and results in renal failure in 20–40% of patients over 25 years of age. Deposition of IgA1 in the glomerular mesangium is thought to drive the disease. Background image, kindly provided by Tongzhong Ju, Richard D. Cummings, et al.: Human primary colorectal adenocarcinoma cells highly express Tn antigen. A formalin fixed paraffin-embedded tissue section of human primary colorectal adenocarcinoma was immunohistochemically stained with anti-Tn monoclonal antibody (Red) and counter staining with Haemotoxylin (Blue). The tumor cells are highly stained with anti-TnmAb. Cover design by SCHULZGrafik-Design.

During training sessions, sailors rely on feedback provided by the coaches to reinforce their skills and improve their performance. Nowadays, the incorporation of sensors on the boats enables coaches to potentially provide more informed feedback to the sailors. A common exercise during practice sessions, consists of two boats of the same class, sailing side by side in a straight line with different boat handling techniques. Coaches try to understand which techniques are that make one boat go faster than the other. The analysis of the obtained data from the boats is challenging given its multi-dimensional, time-varying and spatial nature. At present, coaches only rely on aggregated statistics reducing the complexity of the data, hereby losing local and temporal information. We describe a new domain characterization and present a visualization design that allows coaches to analyse the data, structuring their analysis and explore the data from different perspectives. A central element of the tool is the glyph design to intuitively represent and aggregate multiple aspects of the sensor data. We have conducted multiple user studies with naive users, sailors and coaches to evaluate the design and potential of the overall tool.
In this paper we prove the approximate controllability of the following semilinear system parabolic equations with delay on the state variable where Ω is a bounded domain in is a n × n non diagonal matrix whose eigenvalues are semi‐simple with non negative real part, the control u belongs to and B is a n × m matrix. Here τ≥0 is the maximum delay, which is supposed to be finite. We assume that the operator L:L2([?τ,0];Z)→Z is linear and bounded with and the nonlinear function f:[0,r] × IRn×IRm→IRn is smooth and bounded. 相似文献
PIC is a language for specifying pictures so that they can be typeset as an integral part of a document preparation system. The basic objects in PIC are boxes, lines, arrows, circles, ellipses, arcs and splines, which may be placed at positions specified absolutely or in terms of previous objects, and labeled with arbitrary text. The example below illustrates the general capabilities of the language. Most of the effort in designing PIC has gone into making it possible to specify the sizes and positions of objects with minimal use of absolute coordinates. This paper describes PIC, with primary emphasis on those aspects of the language that make it easy to use. The paper was typeset using PIC. 相似文献
This paper describes the design and implementation of awk, a programming language which searches a set of files for patterns, and performs specified actions upon records or fields of records which match the patterns. Awk makes common data selection and transformation operations easy to express; for example, is a complete awk program that prints all input lines whose length exceeds 72 characters. The program prints each input line with the first field replaced by its logarithm. The program prints all lines in which the first field is different from the first field of the previous line. Patterns may include boolean combinations of regular expressions and of relational operators on strings, numbers, fields, variables, and array elements. Actions may include: the same matching constructions as in patterns; arithmetic and string expressions and assignments; if-else, while, and for statements; formatted output; and multiple output streams. 相似文献
In this article, a new radiating stub microstrip feed has been investigated with asymmetrical ground plane for generation of circular polarization (CP) in a dielectric resonator antenna (DRA). Here, asymmetrical ground plane and 3 radiating stubs with microstrip feed line are used for generation of 2 different modes namely TE11δ and TE12δ in rectangular DRA. By using mode matching concepts, these modes are responsible for enhancing the impedance bandwidth (TE12δ ie, and ) and axial ratio (AR) bandwidth (TE11δ ie, and ) in proposed antenna. Designed antenna offers measured input impedance bandwidth (|S11| < ?10 dB) and AR bandwidth (AR < 3‐dB) of 44.78%, ranging from 4.6 to 6.9 GHz and 23.32%, ranging from 4.6 to 6.9 GHz, respectively. It has been observed that proposed antenna shows left‐handed CP fields in boresight direction with average gain of 3.15 dBic and radiation efficiency of 90.54%. Designed antenna is suitable for Wi‐MAX (3.3‐3.7 GHz) applications. 相似文献
The increased programmability of graphics hardware allows efficient graphical processing unit (GPU) implementations of a wide range of general computations on commodity PCs. An important factor in such implementations is how to fully exploit the SIMD computing capacities offered by modern graphics processors. Linear expressions in the form of , where A is a matrix, and and are vectors, constitute one of the most basic operations in many scientific computations. In this paper, we propose a SIMD code optimization technique that enables efficient shader codes to be generated for evaluating linear expressions. It is shown that performance can be improved considerably by efficiently packing arithmetic operations into four‐wide SIMD instructions through reordering of the operations in linear expressions. We demonstrate that the presented technique can be used effectively for programming both vertex and pixel shaders for a variety of mathematical applications, including integrating differential equations and solving a sparse linear system of equations using iterative methods.相似文献
