Genome-wide microarray analyses revealed that during biological activation of systemic acquired resistance (SAR) in Arabidopsis, the transcript levels of several hundred plant genes were consistently up- (SAR(+) genes) or down-regulated (SAR(-) genes) in systemic, non-inoculated leaf tissue. This transcriptional reprogramming fully depended on the SAR regulator FLAVIN-DEPENDENT MONOOXYGENASE1 (...

The main focus of this paper is to present application results obtained form airborne campaigns in preparation to future European and International space borne SAR missions that were performed in the last 3 years with the DLR’s multi-mode Experimental SAR (E-SAR) system. During the last decade airborne repeat-pass SAR interferometry has become the most demanded technique for the development of ...

To define the interactions between the absorption of glycyl-L-sarcosine (Gly-Sar; .1mM) and glycine, L-methionylglycine, glycyl-L-leucine, L-carnosine, or Lmethionylglycyl-L-methionyl-L-methionine (each at 5 mM), ovine omasal epithelium was collected from eight wethers (avg. BW = 69 kg) and mounted in parabiotic chambers. [1,2]-[C]Glycyl-L-sarcosine was used as a marker to monitor the presence ...

We investigated the relationships of the two immune-regulatory plant metabolites, salicylic acid (SA) and pipecolic acid (Pip), in the establishment of plant systemic acquired resistance (SAR), SAR-associated defense priming, and basal immunity. Using SA-deficient sid2, Pip-deficient ald1, and sid2 ald1 plants deficient in both SA and Pip, we show that SA and Pip act both independently from eac...

SAR-BM3D is one of the state of the art despeckling algorithms for SAR images. However, when tackling with high resolution SAR images, it often has an unsatisfying despeckling performance in the homogeneous smooth regions, together with a high time complexity. In this paper, a novel downsampled SAR-BM3D despeckling approach combined with edge compensation is proposed. The proposed algorithm con...

Airborne SAR systems allow a flexible ground mapping with high geometric resolution, independent from daytime and weather conditions. This offers the opportunity of using this technology for the analysis of built-up areas. However, the oblique SAR illumination limits the visibility of certain objects in urban areas depending on the viewing direction. Especially at building locations different S...

In this paper SAR raw data and SAR image data compression is addressed. For SAR raw data compression we suggest a modified FFT-BAQ. Significant advantages in performance are achieved compared to the standard BAQ and integration in the processing chain is feasible to reduce computational requirements. SAR image compression is mainly performed in wavelet domain. Depending on the application a con...

NY-SAR-35 is a cancer/testis (CT) antigen that was identified by serological analysis of recombinant complementary DNA expression libraries. The gene encoding NY-SAR-35 is located on the × chromosome and is aberrantly expressed in a number of cancer types and germ cells, such as those in the testes, but not in normal tissue. It has been reported that treatment with a demethylating agent induced...

in recent years, synthetic aperture radar (sar) images have played an important role in the detection and monitoring of ground targets because of their advantages such as independence from climatic conditions and sensitivity to the target geometry. the complexity of sar imaging sensors, especially in the conversion process from raw data to image, has made it difficult to interpret the behavior ...
