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.

Validation of variants and structural parameters for mining systems for thin ore bodies

open access: yesIOP Conference Series: Earth and Environmental Science, 2020
Abstract The current mining of thin and steeply dipping ore bodies features depth down to 700–1100 m below ground surface, increased dimension of various-purpose pillars and, as consequence, higher mineral loss and overall degradation of mining efficiency.

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.

Distribution of choline acetyltransferase (ChAT) immunoreactivity in the brain of the teleost cyprinus carpio [PDF]

open access: yes, 2018
Cholinergic systems play a role in basic cerebral functions and its dysfunction is associated with deficit in neurodegenerative disease. Mechanisms involved in human brain diseases, are often approached by using fish models, especially cyprinids, given ...

Pathogen-host reorganization during Chlamydia invasion revealed by cryo-electron tomography [PDF]

open access: yes, 2014
Invasion of host cells is a key early event during bacterial infection, but the underlying pathogen-host interactions are yet to be fully visualised in three-dimensional detail.

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 ...

Body engineering structure for ZnO thin-film transistors: a Schottky-contact-merged ZnO TFT [PDF]

open access: yesJournal of Information Display, 2013
In this paper, a new body engineering structure for ZnO thin-film transistors (TFTs), a Schottky-contact-merged (SCM) ZnO TFT, is proposed, in which the Schottky contact is formed on the body of the ZnO TFT to improve the electrical characteristics without requiring an additional mask and process.

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 ...

Estratigrafía de Sr y evolución sedimentaria de los depósitos marinos del Mioceno temprano en el antepaís del norte de la Cuenca Austral (o Magallanes), Argentina [PDF]

open access: yes, 2015
Early Miocene shallow marine deposits in the region of Lago Posadas-Meseta Belgrano (Argentina) represent part of the “Patagoniense” transgression, an Atlantic marine incursion that flooded large part of Patagonia, including the Austral (foreland) Basin (
