Correlations, Risk and Crisis: From Physiology to Finance

, 2009
We study the dynamics of correlation and variance in systems under the load of environmental factors. A universal effect in ensembles of similar systems under the load of similar factors is described: in crisis, typically, even before obvious symptoms of

Solar activity and the weather [PDF]

The attempts during the past century to establish a connection between solar activity and the weather are discussed; some critical remarks about the quality of much of the literature in this field are given.

Особливості структуроутворення вторинного карбіду кремнію, синтезованого в умовах взаємодії нанорозмірного нестехіометричного карбіду кремнію з оксидом заліза [PDF]

, 2017
Вивчено взаємодію між нанодисперсним порошком твердого розчину вуглецю в карбіді кремнію та оксидом заліза при високотемпературному нагріві. Досліджено фазовий склад та морфологію отриманого порошкового продукту.

A synoptic approach to sun-weather investigations [PDF]

The advantages of a regular program of daily observations of the magnetosphere, ionosphere and atmosphere are described. Such synoptic observations may be one of the best routes to understanding the physical mechanisms involved in sun-weather influences.

Average high latitude magnetic field: Variations with interplanetary sector and with season. 2: Comparison of disturbance levels and discussion of ionospheric currents [PDF]

Average high latitude magnetic field data from northern observatories are examined for three ranges of magnetic disturbance level, Kp = 1 minus to 1+,2 minus to 3+, and or = 4 minus.

Solar generated quasi-biennial geomagnetic variation [PDF]

The existence of highly correlated quasi-biennial variations in the geomagnetic field and in solar activity is demonstrated. The analysis uses a numerical filter technique applied to monthly averages of the geomagnetic horizontal component and of the ...

Studies of h/e Aharonov-Bohm Photovoltaic Oscillations in Mesoscopic Au Rings

, 1996
We have investigated a mesoscopic photovoltaic (PV) effect in micron-size Au rings in which a dc voltage Vdc is generated in response to microwave radiation. The effect is due to the lack of inversion symmetry in a disordered system.
