In modern societies where fighting crime has a long history, establishing effective methods for crime prevention is of high significance. For this purpose, police departments worldwide undertake efforts to analyze past crime data. They aim to detect the most prolific crime areas and predict their development, in order to direct their prevention efforts. In parallel, scholars investigate possibi...

Ishaemic heart disease is one of the world’s most important causes of mortality, so improvements and rationalization of diagnostic procedures would be very useful. The four diagnostic levels consist of evaluation of signs and symptoms of the disease and ECG (electrocardiogram) at rest, sequential ECG testing during the controlled exercise, myocardial scintigraphy and finally coronary angiograph...

It is common in econometric applications that several hypothesis tests are carried out at the same time. The problem then becomes how to decide which hypotheses to reject, accounting for the multitude of tests. In this paper, we suggest a stepwise multiple testing procedure which asymptotically controls the familywise error rate at a desired level. Compared to related single-step methods, our p...

in this paper, the quantitative structure activity-relationship (qsar) of the ccr2b receptor inhibitors was scrutinized. firstly, the molecular descriptors were calculated using the dragon package. then, the stepwise multiple linear regressions (sw-mlr) and the genetic algorithm multiple linear regressions (ga-mlr) variable selection methods were subsequently employed to select and implement th...

the chamomile species of anthemis triumfettii (l.) all is one of important medicinal plant belong to compositae family and it grows as wild species in zagros and alborz mountains, iran. the aim of this study was to evaluation of morphological and phenological traits and their relationships with essential oil. seeds of seven accessions were sown in jiffy pots and transferred to field using rando...

plant biomass is an important factor for determining arid and semi-aridrangelands capacity. due to the lack of proper and annual sampling of rangelands, there areno suitable data to determine biomass, range condition and proper range managementoperations. plant biomass is one of the measurable attributes that can be assessed inrangeland studies. since the clip and weight method is destructive a...

Abstract In this paper, a two-stage block hypothesis testing following the idea of Fan, Lin and Cheng (2004) is proposed for massive data regression analysis. Variables selection criteria incorporating with classical stepwise procedure are also developed to select significant explanatory variables. Simulation study confirms that our approach is more accurate in the sense of achieving the nomina...

The Italian Federation of Healthcare Trusts and Municipalities promoted a national initiative (LITIS, Italian acronym for: Levels of Technological Innovation in Healthcare), to assist its members in the governance of the eHealth phenomenon. The LITIS model spans over the complete spectrum of the eHealth support to care and administrative processes, from two perspectives: the Functions F (servic...

A stepwise degradation of the oligosaccharide part of moenomycin A (2) was performed. The degradation products were assayed for antibiotic activity both in vivo and in an E.coli cell-free system. Units E, F, G, H, and I have been found -to be essential for full biological (in vitro) activity. _It is suggested that 2 is a competitive inhibitor of the peptidoglycan polymerase.
