Extranodal CD56+ EBV- lymphoma at extranasal sites is a clinically less aggressive malignancy and displays less necrosis than CD56+ EBV+ lymphoma. Because CD56+ EBV+ TCR+ lymphomas show similar pathological and clinical findings to CD56+ EBV+ TCR- lymphomas, nasal-type NK/T-cell lymphomas at extranasal sites should be diagnosed as such on the basis of EBV+, cytotoxic T or NK phenotype irrespective of the genotype determined by molecular study.

The subsidence rate in a reclaimed coastal land has been estimated by using JERS-1 L-band SAR two-pass differential interferometry. Measurement of subsidence rate during reclamation is difficult to obtain as a two-dimensional subsidence map based on sparsely distributed field measurements is required. Owing to the severe temporal decorrelation induced by frequent soil loading and intense deformation gradients, the L-band was found to be effective for observing subsidence in reclaimed land. We evaluated the accuracy of the estimated subsidence rate using field measurements obtained by a magnetic probe extensometer from 42 ground stations. A two-dimensional subsidence map was generated from seven qualified pairs. The correlation coefficient R between the two-dimensional radar measurements and the in situ data was 0.87 with a rms error of 1.42 cm. Two interferometric pairs obtained from an adjoining JERS-1 path were also used to verify the results. Independent estimations from the two different JERS-1 paths correlated each other with correlation coefficients R of 0.97 and 0.80. The main sources of the error were the reference DEM errors and additional phase noises calculated from phase fluctuation at stable points. The error from these two sources was ¡1.27 cm. The estimated maximum subsidence was about 60 cm over 352 days. The results demonstrate that L-band differential SAR interferometry is a useful tool in geological engineering applications.

Yashin, I. (2013 JINST 8 P07012ABSTRACT: The Slewing Mirror Telescope (SMT) was proposed for rapid response to prompt UV/optical photons from Gamma-Ray Bursts (GRBs). The SMT is a key component of the UltraFast Flash Observatory (UFFO)-pathfinder, which will be launched aboard the Lomonosov spacecraft at the end of 2013. The SMT utilizes a motorized mirror that slews rapidly forward to its target within a second after triggering by an X-ray coded mask camera, which makes unnecessary a reorientation of the entire spacecraft. Subsequent measurement of the UV/optical is accomplished by a 10 cm aperture Ritchey-Chrètien telescope and the focal plane detector of Intensified Charge-Coupled Device (ICCD). The ICCD is sensitive to UV/optical photons of 200-650 nm in wavelength by using a UV-enhanced S20 photocathode and amplifies photoelectrons at a gain of 10 4 -10 6 in double Micro-Channel Plates. These photons are read out by a Kodak KAI-0340 interline CCD sensor and a CCD Signal Processor with 10-bit Analog-to-Digital Converter. Various control clocks for CCD readout are implemented using a Field Programmable Gate Array (FPGA). The SMT readout is in charge of not only data acquisition, storage and transfer, but also control of the slewing mirror, the ICCD high voltage adjustments, power distribution, and system monitoring by interfacing to the UFFO-pathfinder. These functions are realized in the FPGA to minimize power consumption and to enhance processing time. The SMT readout electronics are designed and built to meet the spacecraft's constraints of power consumption, mass, and volume. The entire system is integrated with the SMT optics, as is the UFFO-pathfinder. The system has been tested and satisfies the conditions of launch and those of operation in space: those associated with shock and vibration and those associated with thermal and vacuum, respectively. In this paper, we present the SMT readout electronics: the design, construction, and performance, as well as the results of space environment test.
