Accountability for disinformation in times of covid-19

2022

Nelabvēlīgās informācijas plašais tvērums liek vairumam sabiedrībā ar vien uzmanīgāk vērtēt informāciju sociālajos tīklos un masu mēdijos, bet arī nekritiski domājošā sabiedrības daļa ir jāpasargā no šādas bīstamas informācijas it īpaši globālās pandēmijas laikā, kad plašie pamattiesību ierobežojumi un ikdienas saasinājumi vājina uzticību valdībai. It īpaši nelabvēlīgas informācijas izplatīšanas ierobežojumi ir nepieciešama virtuālajā vidē, jo 21. gs. ir pavēris jaunas iespējas daļēji vai pilnīgi nepatiesas informācijas ātrai izplatīšanai. Pašlaik Latvijā nav skaidri izveidota doktrīna, kā efektīvi aizsargāt nelabvēlīgās informācijas aizskartās cilvēktiesības, jo to traucē plašais aizsardzī…

Transfection of lipoma cells with papilloma bovine virus subgenomic fragment.

1991

Abstract Lipoma cells with consistent chromosomal aberration have been transfected with plasmids carrying papilloma bovine virus subgenomic fragment (PBV 69). The succesful transformation of the cells was ascerted on the changed growth pattern of the cells in liquid medium, colony formation in soft agar and modified cell appearrance in electron microscopy; transfection with PBV 69 has not been, however, sufficient to immortalize lipoma cells.

Molecular Basis of SARS-CoV-2 Nsp1-Induced Immune Translational Shutdown as Revealed by All-Atom Simulations.

2021

The severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) pandemic represents the most severe global health crisis in modern human history. One of the major SARS-CoV-2 virulence factors is nonstructural protein 1 (Nsp1), which, outcompeting with the binding of host mRNA to the human ribosome, triggers a translation shutdown of the host immune system. Here, microsecond-long all-atom simulations of the C-terminal portion of the SARS-CoV-2/SARS-CoV Nsp1 in complex with the 40S ribosome disclose that SARS-CoV-2 Nsp1 has evolved from its SARS-CoV ortholog to more effectively hijack the ribosome by undergoing a critical switch of Q/E158 and E/Q159 residues that perfects Nsp1's interactions…

Vispārinātie lineārie modeļi skaita tipa datu analīzei

2022

Bakalaura darbs ir veltīts vispārināto lineāro modeļu, kas piemēroti skaita tipa datu analīzei, teorijas apskatam. Darbā apskatīts Puasona regresijas modelis, kā arī modeļi, kas piemēroti pārāk lielas dispersijas gadījumā (kvazi-Puasona un negatīvā binomiālā sadalījuma regresijas modeļi). Skaita tipa datos var būt situācijas, kad liels datu daudzums ir 0, tāpēc šādu datu analīzei aprakstīti īpaši piemēroti modeļi, jo iepriekšminētie modeļi šādiem datiem nevar sniegt korektus novērtējumus. Atsevišķi tika aprakstīta arī empīriskās ticamības funkcijas metode vispārināto lineāro modeļu koeficientu novērtēšanai un ticamības intervālu konstruēšanai, kuru var izmantot Puasona modeļa gadījumā. Darb…

Impacts of Touch Screen Size, User Interface Design, and Subtask Boundaries on In-Car Task's Visual Demand and Driver Distraction

2020

Visual distraction by secondary in-car tasks is a major contributing factor in traffic incidents. In-car user interface design may mitigate these negative effects but to accomplish this, design factors’ visual distraction potential should be better understood. The effects of touch screen size, user interface design, and subtask boundaries on in-car task's visual demand and visual distraction potential were studied in two driving simulator experiments with 48 participants. Multilevel modeling was utilized to control the visual demands of driving and individual differences on in-car glance durations. The 2.5” larger touch screen slightly decreased the in-car glance durations and had a diminis…

Explicit behavioral detection of visual changes develops without their implicit neurophysiological detectability

2011

Change blindness is a failure of reporting major changes across consecutive images if separated, e.g., by a brief blank interval. Successful change detection across interrupts requires focal attention to the changes. However, findings of implicit detection of visual changes during change blindness have raised the question of whether the implicit mode is necessary for development of the explicit mode. To this end, we recorded the visual mismatch negativity (vMMN) of the event-related potentials (ERPs) of the brain, an index of implicit pre-attentive visual change detection, in adult humans performing an oddball-variant of change blindness flicker task. Images of 500 ms in duration were prese…
