Useful relations for the analysis of stellar scintillation at the entrance pupil of a telescope.

The development of new techniques for characterizing atmospheric optical turbulence (OT) has become an active topic of research again in recent years. In order to facilitate these studies, we reconsidered known theoretical results and obtained some new practically useful conclusions. We introduce a dimensionless Fresnel filter, which allows us to approximate a polychromatic weighting function (WF) by a monochromatic one with a typical precision of several percent.

[The link of platelet cytochrome C-oxidase activity with some clinical parameters of depression in elderly patients].

Objective: To search for correlations between platelet cytochrome c-oxidase (COX) activity and the quality of therapeutic outcomes and other clinical parameters of depression in elderly patients.

Material And Methods: Twenty elderly women, aged 55-78 years, with depressive episodes in recurrent depressive disorder (RDD) or bipolar affective disorder (BD) were studied. COX activity and severity of depression were evaluated twice: before the beginning of antidepressant treatment and at the 28-th day of the therapy, using the Hamilton Depression Rating Scale (HAMD-17) and the Hamilton Anxiety Rating Scale (HAM-A).

[Augmentation with carnicetine for late depression].

Aim: Comparative evaluation of the efficacy and safety of antidepressant monotherapy and complex antidepressant therapy in combination with carnicetine in the treatment of depression in elderly patients in a psychiatric hospital.

Material And Methods: Two groups of hospitalized patients, aged from 60 to 79 years, with mild or moderate depression (according to ICD-10), comparable in basic demographic and clinical characteristics, received mono- or complex (in combination with carnicetine) antidepressant therapy for 8 weeks. Treatment efficacy was assessed with HAM-D, HARS, CGI-S and CGI-I; the level of cognitive activity was assessed with MMSE, the 10-word memory test and clock drawing test.

Significant and variable linear polarization during the prompt optical flash of GRB 160625B.

Newly formed black holes of stellar mass launch collimated outflows (jets) of ionized matter that approach the speed of light. These outflows power prompt, brief and intense flashes of γ-rays known as γ-ray bursts (GRBs), followed by longer-lived afterglow radiation that is detected across the electromagnetic spectrum. Measuring the polarization of the observed GRB radiation provides a direct probe of the magnetic fields in the collimated jets.
