Some reports about the Jewish minority in Latvia in the 18th and 19th centuries
06.02.2022. 21.30 Saturs
Article is taken from: Humanities and Social Sciences . Latvia. 1994, 2 (3). pp. 22–32 . Author: Prof. Gvido Straube , a historian, Faculty of History and Philosophy of the University of Latvia, e-mail: gvido.straube@lu.lv It is still difficult today to precisely determine the first moment at which Jews arrived in Latvia. Similarly, we cannot state with certainty, whether they were here during the age of the Livonian state, but when the confederacy collapsed and had its lands included in the territory of the still-mighty Polish-Lithuanian union, agreements were signed which stated that the Jews had no right to conduct business or trade or even to live in the territory of the former Livonian state. This statement does not directly testify to the presence of Jews in the area at the time, but neither does it rule out the possibility that Jews were present in the area covered by the Business was not always a secure or clean thing in the 19th century agreements. It is difficult

Dinamisko sistēmu struktūru saglabājošie neironu tīkli

We consider SMILES string representation of molecules. To encode and decode SMILES we have considered three multi-layer recurrent neural network architectures: Elman (RNN), long short-term memory (LSTM), and gated recurrent unit (GRU). To validate our method, we have selected and tested two types of data sets, that is, unique (target specific inhibitors (SIRT1 and p450)) and diverse ( all drug bank molecules ). Optimal training strategies and computational efficiency of all three methods were investigated. For all three methods generated SMILES are screened on the regression model. In this study, MACCS fingerprints were used as the features to develop machine learning regression models. The top-ranked molecules are further validated using structure-based ranking approaches such as molecular docking to study molecular-level interactions. Our results demonstrate that from all three DGMs, the model with GRU was the most efficient algorithm in training as well as in producing the largest
