S U M M A R Y . Forty-three natural alkali feldspars have been homogenized and used to correlate d.~01 with wt % K20. The regression of Or on dg01 is Or (wt %) = 465"5 d~01 (~)-1877"5, and is comparable to that obtained on an exchanged orthoclase (Wright, I968). A deviation from the Orville (I963, I967) determinative line for synthetic sanidine-albite is greatest at the high potassium end of th...

Compact polarimetric (CP) data exploitation is currently of growing interest considering the new generation of such Synthetic Aperture Radar (SAR) systems. These systems offer target detection and classification capabilities comparable to those of polarimetric SARs (PolSAR) with less stringent requirements. A good example is the RADARSAT Constellation Mission (RCM). In this paper, some characte...

Synthetic food dyes were separated by capillary zone electrophoresis using an alkaline phosphate buffer as background electrolyte. The precision had a relative standard deviation of less than 0.5 % for the run-to-run migration times and 2 % for the peak areas with buffer replenishment after each run. The detection limit for the individual dyes was about 1 ng using a 50-μm internal diameter Agil...

The paper presents a robust version of a recent anisotropic orthogonal Procrustes algorithm that has been proposed to solve the socalled camera exterior orientation problem in computer vision and photogrammetry. In order to identify outliers, that are common in visual data, we propose an algorithm based on Least Median of Squares to detect a minimal outliers-free sample, and a Forward Search pr...

We report the results of operator state fluctuations in gene expression for the entire bacterial growth cycle, using single-cell analysis and synthetic unregulated and negative-feedback transcription regulatory gene circuits. In the unregulated circuit, during the cell cycle, we observe a crossover from log-normal-to-normal distribution of expressed proteins and an unusual linear dependence of ...

Detecting anomalies in time series data is a problem of great practical interest in many manufacturing and signal processing applications. This paper presents a novelty detection algorithm inspired by the negative-selection mechanism of the immune system, which discriminates between self and other. Here self is deened to be normal data patterns and non-self is any deviation exceeding an allowab...

The title compound, C(7)H(6)S(5), contains a 5-yl-idene-1,3-dithiolo[4,5-d][1,3]dithiole-2-thione framework, which is an important synthetic precursor of multi-dimensional organic superconductors and conductors. The mol-ecular framework is planar with an r.m.s. deviation of 0.012 Å for the non-H atoms. In the crystal structure, mol-ecules are linked by short inter-molecular S⋯S inter-actions [3...

The crystal structure of norsethite, BaMg(C03h, [a = 5.022(1) Á, e = 16.77(1) Á, space graup Rjm, Z = 3] was reinvestigated by single crystal X-ray methods working with both natural and synthetic material. The main features of an earlier structure determination using powder data were confirmed, but no significant deviation of the atomic arrangement from Rjm was found. The carbonate group is apl...
