Das Bleigewicht aus dem Hofareal der Fürstin von Vix auf dem Hochplateau des Mont Lassois.
2021
Das Bleigewicht aus dem Hofareal der Fürstin von VixDer Mont Lassois bei Vix, Dép. Côte d’Or, zählt neben der Heuneburg zu den am besten erforschten Fürstensitzen imfrühkeltischen Westhallstattkreis. 1953 wurde das späthallstattzeitliche Fürstinnengrab von Vix entdeckt. Im Rahmendes deutsch-französischen Forschungsprojektes »Keltische Fürstensitze westlich des Rheins« (1991-1997) und desfranzösischen PCR-Projektes (Projet collectif de recherche) »Vix et son environnement« (seit 2002) mit Beteiligungder Universitäten Dijon, Kiel, Wien und Zürich wurden die Altgrabungen (1930-1974) wieder aufgenommen. Bei derUntersuchung des späthallstattzeitlichen Hofareals der Fürstin von Vix auf dem Hochpl…

Thalassobius mediterraneus gen. nov., sp. nov., and reclassification of Ruegeria gelatinovorans as Thalassobius gelatinovorus comb. nov.
2005
A Gram-negative, slightly halophilic, non-pigmented, strictly aerobic, chemo-organotrophic bacterium was isolated from sea water off the western Mediterranean coast near Valencia (Spain). This strain was able to grow on several organic acids and amino acids added to a minimal medium as carbon sources, but used few carbohydrates or yielded slight growth when sugars were used. Phylogenetic analysis based on an almost complete 16S rRNA gene sequence revealed that strain XSM19T was a member of the Roseobacter group within the ‘Alphaproteobacteria’, with its closest phylogenetic neighbour being Ruegeria gelatinovorans (97·6 % sequence similarity). Following a polyphasic approach, it was conclude…

Lielas dimensijas vektorautoregresīvo modeļu izmantošana prognozēšanai
2016
Vektorautoregresīvā procesa (VAR) modeļi ir parādījuši sevi, kā efektīva metode makroekonomisko laikrindu prognozēšanai. Taču VAR trūkums ir tāds, ka modeļa parametru telpa pieaug kvadrātiski, pievienojot modelim jaunu mainīgo. Tā kā mūsdienās valstu ekonomikas paliek savstarpēji saistītas, paliek aktuālāks jautājums par to, kā modelī iekļaut nemodelējamus ekzogēnos mainīgos. Vektorautoregresīvā procesa modelis ar ekzogēniem mainīgajiem (VAR-X ) ļauj iekļaut nemodelējamus mainīgos, taču tāpat sastopas ar dimensionalitātes problēmu. Lai uzlabotu retāka periodiskuma daudzdimensiju datu prognozēšanu, šajā darbā teorētiski izpētam regularizitētos VAR un VAR-X modeļus, kas izretina parametru tel…
LASSO regression via smooth L1-norm approximation
2010
This paper discusses estimation of regression model with LASSO penalty when the L1-norm is replaced with its parametric smooth approximation. The resulting parameter estimators are more manageable than those from standard LASSO, standard errors are easy computed via a sandwich formula, and the model degrees of freedom may be computed straightforwardly. Moreover the resulting objective function may be minimized using usual optimization algorithms for regular models, for instance Newton-Raphson or iterative least squares.
