Convolutional Neural-Network-Based Reverse-Time Migration with Multiple Reflections

open access: yesSensors, 2023
Reverse-time migration (RTM) has the advantage that it can handle steep dipping structures and offer high-resolution images of the complex subsurface.

Minerals and ore deposits exploration using meta-heuristic based optimization on magnetic data

open access: yesContributions to Geophysics and Geodesy, 2020
The difficulties in unravelling the tectonic structures, in some cases, prevent the understanding of the ore bodies' geometry, leading to mistakes in mineral exploration, mine planning, evaluation of ore deposits, and even mineral exploitation.

Extension of experimental statistical energy analysis to structural vibration with low modal density

open access: yesNihon Kikai Gakkai ronbunshu, 2019
Statistical energy analysis (SEA) is a method for understanding energy transfer paths related to vibration noise generation. In SEA, a target object is separated virtually into subsystems among which the transfer of vibration energy can be quantified ...

Telocytes and their structural relationships with surrounding cell types in the skin of silky fowl by immunohistochemistrical, transmission electron microscopical and morphometric analysis

open access: yesPoultry Science, 2021
: Telocytes (TCs), a novel type of interstitial cells, were identified in various animals. Since TCs have not observed in avian skin, hence, we carried out immunohistochemistrical and transmission electron microscopical studies in the skin of the silky ...

In cultured cells the baculovirus P10 protein forms two independent intracellular structures that play separate roles in occlusion body maturation and their release by nuclear disintegration.

open access: yesPLoS Pathogens, 2019
P10 is a small, abundant baculovirus protein that accumulates to high levels in the very late stages of the infection cycle. It is associated with a number of intracellular structures and implicated in diverse processes from occlusion body maturation to ...

The pendulum type surfaces with congruential cross sections

open access: yesStructural Mechanics of Engineering Constructions and Buildings, 2021
The article discusses new kinematic surfaces that can be attributed to the class of surfaces of congruent cross sections. The surfaces of congruent cross sections were first identified in a separate class by Professor I.I. Kotov. Circular, elliptical and

Composite material identification as micropolar continua via an optimization approach

open access: yesComposites Part C: Open Access, 2023
A strategy based on material homogenization and heuristic optimization for the structural identification of composite materials is proposed. The objective is the identification of the constitutive properties of a micropolar continuum model employed to ...

The Characteristics of Deep-Water Gravity Flow in the Sublacustrine Fan of the Upper Triassic Yanchang Formation in the Huachi Area, Ordos Basin

open access: yesApplied Sciences
In the Ordos Basin, one of the most important oil- and gas-bearing basins, the Triassic Yanchang Formation has formed important source rocks, but is also a typical representative of continental deep-water sedimentation.

Graph-Theoretic Approach for the Dynamic Simulation of Flexible Multibody Systems

open access: yesAdvances in Mechanical Engineering, 2012
This paper provides a general description of a variational graph-theoretic formulation for simulation of flexible multibody systems (FMSs) which includes a brief review of linear graph principles required to formulate this algorithm.

White feces syndrome of shrimp arises from transformation, sloughing and aggregation of hepatopancreatic microvilli into vermiform bodies superficially resembling gregarines. [PDF]

open access: yesPLoS ONE, 2014
Accompanying acute hepatopancreatic necrosis disease (AHPND) in cultivated Asian shrimp has been an increasing prevalence of vermiform, gregarine-like bodies within the shrimp hepatopancreas (HP) and midgut.
