//        "Declarative visualization grammars can accelerate development, facilitate retargeting across platforms, and allow language-level optimizations. However, existing declarative visualization languages are primarily concerned with visual encoding, and rely on imperative event handlers for interactive behaviors. In response, we introduce a model of declarative interaction design for data visualizations. Adopting methods from reactive programming, we model low-level events as composable data streams from which we form higher-level semantic signals. Signals feed predicates and scale inversions, which allow us to generalize interactive selections at the level of item geometry (pixels) into interactive queries over the data domain. Production rules then use these queries to manipulate the visualization’s appearance. To facilitate reuse and sharing, these constructs can be encapsulated as named interactors: standalone, purely declarative specifications of interaction techniques. We assess our model’s feasibility and expressivity by instantiating it with extensions to the Vega visualization grammar. Through a diverse range of examples, we demonstrate coverage over an established taxonomy of visualization interaction techniques.",

//        "We present Reactive Vega, a system architecture that provides the first robust and comprehensive treatment of declarative visual and interaction design for data visualization. Starting from a single declarative specification, Reactive Vega constructs a dataflow graph in which input data, scene graph elements, and interaction events are all treated as first-class streaming data sources. To support expressive interactive visualizations that may involve time-varying scalar, relational, or hierarchical data, Reactive Vega’s dataflow graph can dynamically re-write itself at runtime by extending or pruning branches in a data-driven fashion. We discuss both compile- and run-time optimizations applied within Reactive Vega, and share the results of benchmark studies that indicate superior interactive performance to both D3 and the original, non-reactive Vega system."

"Autoritatile Republicii Moldova s-au sesizat pe marginea propagarii virusului la sfarsitul lunii ianuarie, dupa care situatia epidemiologica la infectia cu noul tip de coronavirus a fost examinata de Comisia Nationala Extraordinara de Sanatate Publica (CNESP) la 2 februarie 2020. In dependenta de gradul de risc pentru sanatatea publica, Comisia a instituit succesiv din 24 februarie pana la 13 martie grad de alerta cod galben, portocaliu si rosu. Ultimul a fost atribuit dupa ce in Republica Moldova fusese confirmate 6 cazuri de COVID-19, iar Organizatia Mondiala a Sanatatii a anuntat la 11 martie faza de transmitere pandemica a virusului. Principale masuri aprobate de Comisie au vizat suspendarea procesului educational, sistarea transportului aerian regulat cu zonele afectate de pandemia COVID-19, intreruperea activitatii institutiilor de agrement, antrenament si recreere si a intrunirilor religioase. Cresterea numarului de cazuri de infectie cu virusul COVID-19 a determinat CNESP sa extinda la 15 martie numarul masurilor preventive prin sistarea transportului feroviar international de pasageri si oprirea temporara a activitatii comerciale, cu exceptia magazinelor alimentare, farmaciilor si a benzinariilor. Totusi, avand cod rosu de alerta si un focar de infectie in doua din satele raionului Hincesti, autoritatile nu au interzis desfasurarea alegerilor parlamentare noi in circumscriptia uninominala nr. 38, Hincesti pe 15 martie 2020, care au fost castigate de candidatul PSRM.",

"Numarul cazurilor active este obtinut dupa deducerea numarului de persoane vindecate si decedate din numarul total de cazuri confirmate. Dupa ce catre inceputul lunii mai infectia a atins un platou de cazuri noi, redeschiderea tuturor magazinelor si reluarea serviciilor religioase, precum si organizarea mai multor evenimente publice dedicate zilei de 9 mai in Balti, Chisinau, Comrat si Tiraspol a generat o crestere rapida de cazuri noi, care a culminat pe 20 mai. Ulterior, pe parcursul unei saptamani s-a produs o scadere semnificativa a numarului cazurilor active. Ridicarea mai multor restrictii dupa incetarea starii de urgenta a rasturnat aceasta tendinta si a provocat o explozie de noi cazuri. Incepand cu ultima saptamana din luna mai, evolutia cazurilor active arata o crestere continua, cu numarul maxim de cazuri 6 629, inregistrat pe 2 august 2020."
