Results of joint ground-based measurements of vertical structures of ozone and temperatures with the use
microwave and lidar technical equipment during stratospheric warming are presented. During winter warming
(December 2012 – January 2013) appreciable variations of ozone concentration and temperature in the middle
atmosphere are registered. Changes of ozone concentration at height levels from 25 to 60 km increased by 1.5 –
2 times, the amplitude of their oscillations thus has considerably increased. The peak of a positive deviation
of temperature from its monthly average value reached 70 K at a height of 30 km. Daily ozone oscillations
at a height of 60 km, connected with sunset and sunrise, were about 30%.

We investigate the spatial overlap of successive spin configurations in Markov chain Monte Carlo simulations using the local Metropolis algorithm and the Svendsen-Wang and Wolff cluster algorithms. We examine the dynamics of these algorithms for two models in different universality classes: the Ising model and the Potts model with three components. The overlap of two ...

We investigate the boundary separating regular and chaotic dynamics in the generalized Chirikov map, an extension of the standard map with phase-shifted secondary kicks. Lyapunov maps were computed across the parameter space (K,K(α, τ)) and used to train a convolutional neural network (ResNet18) for binary classification of dynamical regimes. The model reproduces the known critical ...

Introduction. Skin temperature has been recognized as a potential marker of emotional arousal, with studies demonstrating temperature changes in response to various emotional stimuli. However, temperature in different body parts and in different basic emotions has not been studied sufficiently. Our study aimed to investigate whether basic emotions could be reflected in temperature changes at ...

In this study, we analyze the dielectric function of high-Tc cuprates as a function of doping level, taking into account the full energy band dispersion within the CuO2 monolayer. In addition to the conventional two-dimensional (2D) gapless plasmon mode, our findings reveal the existence of three anomalous branches within the plasmon spectrum. Two of these branches ...

Significant reserves of methane (CH4) are held in the Arctic shelf, but the release of CH4 to the overlying ocean and, subsequently, to the atmosphere has been believed to be restricted by impermeable subsea permafrost, which has sealed the upper sediment layers for thousands of years. Our studies demonstrate progressive degradation of subsea permafrost which controls ...

The development of new algorithms for simulations in physics is as important as the development of new analytical methods. In this paper we present a comparison of the recently developed microcanonical population annealing (MCPA) algorithm with the rather mature Wang-Landau algorithm. The comparison is performed on two cases of the Potts model exhibiting a first ...

Until now, field measurements have been the main method for inventorying urban forests. The advent of LiDAR and remote sensing technology has made a breakthrough possible in terms of the effort and quality balance. LiDAR technology allows a three-dimensional reconstruction of aboveground biomass in the form of a point cloud and thereby to classify vegetation ...

Nabokoite family compounds ACu7(TeO4)(SO4)5Cl (A=Na, K, Cs, Rb) are one of the candidates for the evasive spin-liquid state predicted for highly-frustrated square kagome lattice (SKL). Their magnetic subsystem includes SKL layers decorated by additional copper ions. All members of this family are characterized by quite high Curie-Weiss temperatures (∼80−200 K), but magnetic ordering was reported ...

It has been experimentally established that larger colonies of Dynamena pumila (Hydrozoa, Cnidaria) grown in the laboratory, including 10–11 young shoots, are less resistant to increases in water temperature to the upper temperature limit of this species (25 °C) than the same smaller colonies with one or two shoots. As the temperature rises, some of ...

as a function of temperature in microdisk lasers with Stranski–Krastanow InAs/InGaAs/GaAs
quantum dots. Near room temperature, the temperature-induced increment of the ground-state

A detailed investigation of a superconducting spin-triplet valve is presented. This spin-valve consists of a superconducting film covering a metal with an intrinsic spiral magnetic order, which could result from competing isotropic exchanges or, if the crystal lattice breaks central symmetry, from asymmetric Dzyaloshinskii-Moriya exchange. Depending on the anisotropy, such a metal may change its ...

Charge transport in amorphous semiconductors having spatially correlated exponential density of states (DOS) has been considered for the arbitrary behavior of the correlation function of random energies. Average carrier velocity is exactly calculated for the quasi-equilibrium (nondispersive) transport regime. For the symmetric exponential DOS with exponential tails for low and high energies and non-positive correlation ...

A major challenge of contemporary marine science is disentangling consequences of climate change from other impacts, and studying non-target species and using historical resources to see long-term trends can meet this need. However, such data can be fragmented, and here, we demonstrate the potential of leveraging across sources for insight. We assembled a variety of ...

The temperature and thermal properties of shelf sediments from the East Siberian, Laptev, and Kara Seas were determined from field investigations. The sediments were in an unfrozen cryotic state (ice-free) and showed negative temperatures, ranging from −1.0 to −1.4 °C. These temperatures imply the presence of widespread subsea permafrost from the shelf to the continental slope ...
