UAVSAR Vertical Velocity Rate Map for the Sacramento-San Joaquin Delta (2009-2015)
Provided are the dat files for the UAVSAR rate map and corresponding uncertainties. The rate map shows vertical velocity values for the Sacramento-San Joaquin Delta with negative values representing subsidence. See Bekaert, D. P., Jones, C. E., An, K., & Huang, M.-H. (2019). Exploiting UAVSAR for a comprehensive analysis of subsidence in the Sacramento Delta. Remote Sensing of Environment, 220, 124–134. doi: 10.1016/j.rse.2018.10.023 for more information on how this data was prepared.Related Publication:

An Economic Analysis of the Bekaert NV Insider Trading Case
This article contains a clinical study of Bekaert NV, the biggest insider trading case inBelgium. Up to now, no economic analysis of this case was ever conducted. It showed thatBelgian courts currently seem to lack knowledge of the functioning of financial markets toassess an insider trading case. Therefore their decisions give little guidance to futurelitigants. Using a law and economics framework, this case study is clarifying in severalaspects compared to a traditional legal analysis. The analysis focuses on two aspects of aninsider trading case. First, the price-sensitive character of the information is examined.Second, the standard of proof was examined

APOLIPOPROTEIN-A-I(MILANO) - SEX-RELATED DIFFERENCES IN THE CONCENTRATION AND COMPOSITION OF APOA-I-CONTAINING AND APO-B-CONTAINING LIPOPROTEIN PARTICLES
The presence of apolipoprotein (apo) A-I(Milano) (A-I(M)) mutant of apoA- I has a marked effect on plasma lipoproteins of A-I(M) carriers including variable hypertriglyceridemia, increased levels of very low density lipoproteins (VLDL), slightly elevated levels of triglyceride-enriched low density lipoproteins (LDL) and greatly reduced levels of high density lipoproteins (HDL). To gain further insight into this dyslipoproteinemic syndrome characterized clinically by the absence of coronary artery disease, we have determined the concentration and composition of apoA- and apoB- containing lipoprotein families in four male and four female carriers and corresponding normal controls. Results have shown that A-I(M) carriers have significantly reduced levels of lipoprotein (LP) A-I (45%), LP-A-I:A-II (60%), and LP-A-II (70%) and significantly increased levels of cholesterol- rich LP-B (67%) and triglyceride-rich LP-B:C, LP-B:C:E, and LP-A-II:B:C:D:E (65%) particles compared to controls. However, there were significant sex- related differences in the levels of apoA- and apoB-containing lipoproteins. Female carriers had significantly higher concentrations of LP-A-I (39 ± 10 vs. 12 ± 6 mg/dl) and LP-A-I:A-II (48 ± 11 vs. 30 ± 6 mg/dl) than male carriers. Furthermore, female carriers had higher levels of LP-B:C (23 ± 18 vs. 6 ± 5 mg/dl) and LP-A-II:B:C:D:E (13 ± 6 vs. 2.3 ± 0.8 mg/dl) but lower concentrations of LP-B (103 ± 52 vs. 152 ± 54 mg/dl) and LP-B:C:E (5 ± 2.5 vs. 13 ± 8 mg/dl) than male carriers. In general, the levels of LP- A-I and LP-A-I:A-II particles correlated positively with the levels of all three types of triglyceride-rich lipoproteins (LP-B(c)) and negatively with the levels of LP-B particles. A comparative study of lipoprotein families in several dyslipoproteinemic states characterized by low levels of HDL has indicated that the characteristic lipoprotein particle profile of A-I(M) carriers results most probably from the selective effect of apoA-I(M) mutant rather than a general reduction in HDL levels. It appears that increased levels of LP-A-II:B:C:D:E particles, an inefficient substrate for lipoprotein lipase, and structurally defective LP-A-I:A-II particles, the normal acceptors of minor apolipoproteins released during lipolysis of triglyceride- rich lipoproteins, may be the main contributing factors to moderate hypertriglyceridemia characteristic of A-I(M) carriers

Going Beyond Counting First Authors in Author Co-citation Analysis
The present study examines one of the fundamental aspects of author co-citation analysis (ACA) - the way co-citation
counts are defined. Co-citation counting provides the data on which all subsequent statistical analyses and mappings
are based, and we compare ACA results based on two different types of co-citation counting - the traditional type that
only counts the first one among a cited work's authors on the one hand and a non-traditional type that takes into
account the first 5 authors of a cited work on the other hand. Results indicate that the picture produced through this non-traditional author co-citation counting contains more coherent author groups and is therefore considerably clearer. However, this picture represents fewer specialties in the research field being studied than that produced through the traditional first-author co-citation counting when the same number of top-ranked authors is selected and analyzed. Reasons for these effects are discussed
Appropriate Similarity Measures for Author Cocitation Analysis
We provide a number of new insights into the methodological discussion about author cocitation analysis. We first argue that the use of the Pearson correlation for measuring the similarity between authors’ cocitation profiles is not very satisfactory. We then discuss what kind of similarity measures may be used as an alternative to the Pearson correlation. We consider three similarity measures in particular. One is the well-known cosine. The other two similarity measures have not been used before in the bibliometric literature. Finally, we show by means of an example that our findings have a high practical relevance.information science;Pearson correlation;cosine;similarity measure;author cocitation analysis
Designing an automated prototype tool for preservation quality metadata extraction for ingest into digital repository
We present a viable framework for the automated extraction of preservation quality metadata, which is adjusted to meet the needs of, ingest to digital repositories. It has three distinctive features: wide coverage, specialisation and emphasis on quality. Wide coverage is achieved through the use of a distributed system of tool repositories, which helps to implement it over a broad range of document object types. Specialisation is maintained through the selection of the most appropriate metadata extraction tool for each case based on the identification of the digital object genre. And quality is sustained by introducing control points at selected stages of the workflow of the system. The integration of these three features as components in the ingest of material into digital repositories is a defining step ahead in the current quest for improved management of digital resources
