Abstract:

In cryoEM 3D reconstruction, noise is spread over the entire 3D space, while the signal is present only within the molecular mask. The signal-to-noise ratio (SNR) within the molecular mask is the SNR of interest in data analysis. Any method that does not apply the molecular mask to noise underestimates the SNR. For instance, Fourier Shell Correlation (FSC) curves recalculated between two half-maps after the data are deposited in the PDB do not apply the molecular mask to noise, consequently providing a misleading impression of resolution. These approaches, relying on calculations without mask

Abstract:

AbstractComputations of the Iwasawa λ -invariant for imaginary quadratic fields showed a discrepancy in the proportion of even and odd traces of certain integers from these imaginary quadratic fields. This paper shows that such a discrepancy is in some sense to be expected and that the proportion of even and odd traces of principal generators of powers of prime ideals in imaginary quadratic fields is related to the 3-primary component of the class group.

At low temperatures, the imaginary part of the zero-frequency relaxation function and the DC resistivity are characterized by the scaling law aTx with the exponent x between 2.5 and 3.

A careful analysis of the set formation process shows a missing component in this solution: the necessity of an assumed imaginary jump out of an infinite universe. Thus a set is formed by a suitable combination of concrete and imaginary operations all of which can be made or assumed by a Turing machine. Some consequences are drawn from this improved analysis of the concept of set, for the theory of sets and for the philosophy and foundations of ma

Abstract:

The properties of composites based on polychlorotryfluoroene with graphene containing 5 % (wt.) obtained by electrochemical dispergasion of graphite electrodes were researched. It is shown that the conductivity of the initial graphene that is determined by the impedance spectroscopy method is caused by the mainly electronic component. The concentration dependence of conductivity at low frequencies and real and imaginary components of the complex dielectric permeability at a frequency of 9 GHz composites significantly changes in the concentration range of 0,25-1%, that is stimulated by the pres

Abstract:

A textual world is a cognitive complex, which combines two elements: a text base, a textual material; a cognitive base – knowledge and ideas of the communiсators. A textual world is divided into a great deal of various imaginary worlds: the author’s world and the personages, which in its turn is subdivided into the world of ideas, the world of desires, knowledge and the world of obligations. By the way, a textual world can be real and unreal or imaginary (M. -L. Rayyan), deictic, attitudinal and epistemic (P. Vert).The purpose of this article is to single out means of formation of an imaginary

Abstract:

The need for nuclear data far from the valley of stability, for applications such as nuclear astrophysics or future nuclear facilities, challenges the robustness as well as the predictive power of present nuclear models. The isovector contribution to the imaginary component of the microscopic optical model potential remains unconstrained at keV energies. Within the Brückner–Hartree–Fock approximation of Jeukenne-Lejeune-Mahaux, it is shown that experimental neutron strength function data favours a strong isovector component that can have a drastic impact on the radiative neutron capture cross

Abstract:

Mahaswetha Devi presents a vivid, truthful portrayal of tribal communitiesin India, capturing their struggles, culture, and resilience. Devi's narrative techniquecombines detailed ethnographic observations with a strong sense of social justice,exposing the exploitation and marginalization faced by these communities. Throughher stories, she gives voice to the voiceless, blending fiction with anthropologicalaccuracy to create a powerful critique of systemic oppression. Her approach not onlyraises awareness but also challenges readers to confront the harsh realities ofIndigenous life and the broa

The comments of Nagendra and Ram Babu mainly center around the sign of the imaginary component in the integral [Formula: see text]. We have defined [Formula: see text] and maintained the consequential algebra throughout. The Hilbert transform we considered is a modified version of Thomas (1969) without any theoretical deviations. Since the modification is elementary, we thought more elaboration was not necessary.

Abstract:

X-ray absorption spectra calculated within an effective one-electron approach have to be broadened to account for the finite lifetime of the core hole. For methods based on Green's function this can be achieved either by adding a small imaginary part to the energy or by convoluting the spectra on the real axis with a Lorentzian. By analyzing the FeK- andL2,3-edge spectra it is demonstrated that these procedures lead to identical results only for energies higher than a few core-level widths above the absorption edge. For energies close to the edge, spurious spectral features may appear if too m

Abstract:

Years ago, just by thinking about it, we discovered the rate of a unit clock in a gravitational field, and, after that, because of the slower clock rate in a gravitational field, that the energy that an energy wave sphere loses becomes its energy of motion. We calculated the radius of a proton energy wave sphere contained in an electron energy wave sphere. We extend the concept of energy wave spheres to imaginary energy wave spheres to explain the change in frequency of the wave in an energy wave sphere. We show that a black hole is an imaginary energy wave sphere with radius alpha and wave ve

Abstract:

The sensitivity of amplitude variations with offset (AVO) to normal‐moveout (NMO) velocity errors has usually been taken to be a significant limitation of the method. However, this sensitivity can, in most cases, be exploited to obtain more accurate velocities from a fully automated procedure. The error due to velocity in the AVO gradient is in phase quadrature with the AVO zero‐offset intercept. Furthermore, if the majority of reflectors within a suitable data window contain a similar gradient quadrature component, then it may be inferred that this component is due to an NMO velocity error.

Abstract:

AbstractIn this article, we show that the wave equation for a free Dirac electron can be represented in a form that is analogous to Maxwell’s electrodynamics. The electron bispinor wavefunction is explicitly expressed in terms of its real and imaginary components. This leads us to incorporate into it appropriate scalar and pseudo-scalar fields in advance, so that a full symmetry may be accomplished. The Dirac equation then takes on a form similar to that of a set of inhomogeneous Maxwell’s equations involving a particular self-source. We relate plane wave solutions of these equations to waves

It is substantiated that the phenomenon of representation has a wide range of meanings and is a necessary stage in cognition, organically connected with thinking, memory, and imagination. A representation can be adequate to reality and at the same time to reality and, at the same time, imaginary, having all the signs of illusion. In this regard, in the section the semantics of the terms imagination, imaginary, and representation are clarified. The terms are

The case when spheroids are arranged in such a way that their major semi-axis belongs to the substrate plane is considered. The relations for the transverse component of the chain polarizability tensor and the frequency of the transverse chain resonance are obtained.
