This study validates statistical estimates of Azerbaijan’s mean spring temperatures up to 2022. Although precise long-term forecasts remain difficult, analysis of meteorological data from 1968–2022 demonstrates that statistical methods

Natural catastrophes and point-like processes Data handling and prevision
Annals of Geophysics, 1998 A frequent approach when attempting to manage a natural catastrophe is in terms of a numerical model, by which we try to forecast its occurrence in space and time. But, sometimes this is difficult or even unrealistic.

Molecular characterization of covRS mutations in M1UK Streptococcus pyogenes
FEBS Open Bio, EarlyView.Group A Streptococcus (GAS) acquires covRS mutations driving a hypervirulent bacterial state, frequently associated with invasive disease‐like necrotizing fasciitis. We demonstrate that the newly emerged M1UK GAS lineage can also acquire these mutations.

TRADING COLLAR, INTRADAY, PERIODICITY, AND STOCK MARKET VOLATILITY [PDF]
Using 5 minute data, we examine market volatility in the Dow Jones Industrial Average in the presence of trading collars. We use a polynomial specification for capturing intraday seasonality.

Investigation of periodicity for dependent observations [PDF]
, 1984 summary:It is proved that Hannan's procedure for statistical test of periodicity in the case of time series with dependent observations can be combined with Siegel's improvement of the classical Fischer's test of periodicity. Simulations performed in the

On horadam sequence periodicity: A new approach [PDF]
, 2015 A so called Horadam sequence is one delivered by a general second\ud order recurrence formula with arbitrary initial conditions.\ud We examine aspects of self-repeating Horadam sequences by\ud applying matrix based methods in new ways, and derive some ...

Bochner-almost periodicity for stochastic processes
, 2012 We compare several notions of almost periodicity for continuous processes defined on the time interval I = R or I = [0,+∞) with values in a separable Banach space E (or more generally a separable completely regular topological space): almost periodicity ...

Malformin A1–mediated cytotoxicity in ovarian cancer cells occurs through pyroptosis and autophagy
FEBS Open Bio, EarlyView.This study investigated the effects of the natural compound Malformin A1 (MA1) on the cytoskeleton that regulates cell proliferation and migration. Disruption of the cytoskeleton can impair these processes and promote cancer cell death. MA1 disrupted cytoskeletal organization, induced DNA damage, inflammation, activated autophagy, and pyroptosis ...
