THEORETICAL FOUNDATIONS AND DETECTION TECHNOLOGY OF ZONES OF ABNORMALLY HIGH PRESSURES (FOR EXAMPLE, OBJECTS OF THE AZOV KUBAN CAVITY, THE KUMO-MANYCH CAVITY AND THE JUNCTION ZONE OF THE CASPIAN CAVITY AND THE KARPINSKI RIDGE)

open access: yesНаука. Инновации. Технологии, 2022
This article presents the theoretical foundations (the concept of tectonic activity and the concept of the mechanism of formation of the structures of the central type and their interpretation, with an assignment of zones of compression, stretching ...

Special rays and structures in general optical systems: generalized magnifications associated with the fundamental properties

open access: yesAfrican Vision and Eye Health, 2010
In aprevious study special rays and structures, including nodal, principal and focal rays and structures, were defined in terms of generalized magnification of reduced inclination of rays across thesystem.  The mathematical structure of the transference,

Reconfigurable Three‐Dimensional Superconducting Nanoarchitectures

open access: yesAdvanced Functional Materials, EarlyView.
3D superconducting nanostructures offer new possibilities for emergent physical phenomena. However, fabricating complex geometries remains challenging. Here 3D nanoprinting of complex 3D superconducting nanoarchitectures is established. As well as propagating superconducting vortices in 3D, anisotropic superconducting properties with geometric ...

Nodal domain distributions for quantum maps

open access: yes, 2003
The statistics of the nodal lines and nodal domains of the eigenfunctions of quantum billiards have recently been observed to be fingerprints of the chaoticity of the underlying classical motion by Blum et al. (Phys. Rev. Lett., Vol.

Golden‐Ratio–Guided Aperiodic Architected Metamaterials with Simultaneously Enhanced Strength and Toughness

open access: yesAdvanced Functional Materials, EarlyView.
Guided by the golden ratio, a class of aperiodic architected metamaterials is introduced to address the intrinsic trade‐off between strength and toughness. By unifying local geometric heterogeneity with global order, the golden‐ratio‐guided aperiodic architecture promotes spatial delocalization of damage tolerence regions, leading to more tortuous ...

Topological semimetal with coexisting nodal points and nodal lines

open access: yesPhysical Review B
Featuring exotic quantum transport and surface states, topological semimetals can be classified into nodal-point, nodal-line, and nodal-surface semimetals according to the degeneracy and dimensionality of their nodes. However, a topological semimetal that possesses both nodal points and nodal lines is rarely reported.

E2F: a nodal point in cell cycle regulation [PDF]

open access: yesBiochimica et Biophysica Acta (BBA) - Reviews on Cancer, 1997
1. IntroductionThe transcription factor E2F was first identified asa factor that interacts with the adenovirus early re-gion 2 E2 promoter. Activation of the E2 promoter.by the adenovirus E1A gene products was shown tobe mediated through the E2F element and did notrequire novel protein synthesis 1 .

C1 neurons: a nodal point for stress? [PDF]

open access: yesExperimental Physiology, 2017
New Findings What is the topic of this review? The C1 neurons (C1) innervate sympathetic and parasympathetic preganglionic neurons plus numerous brain nuclei implicated in stress, arousal and autonomic regulations. We consider here the contribution of C1 to stress‐induced responses. What advances does it highlight?

Spectrally Tunable 2D Material‐Based Infrared Photodetectors for Intelligent Optoelectronics

open access: yesAdvanced Functional Materials, EarlyView.
Intelligent optoelectronics through spectral engineering of 2D material‐based infrared photodetectors. Abstract The evolution of intelligent optoelectronic systems is driven by artificial intelligence (AI). However, their practical realization hinges on the ability to dynamically capture and process optical signals across a broad infrared (IR) spectrum.
