Lorentz-invariant system with quantum mechanical properties

In this work we study potential fluids, within which eddies exist which have quantum mechanical properties because according to Helmholtz they are made up of an integer number of lines and their displacement in a potential medium is a function of a frequency. However, this system is Lorentz-invariant since Maxwell’s equations can be obtained from it, and this is what we demonstrate here. The considered hypothesis is that the electric charge arises naturally as the intensity of the eddy in the potential fluid, that is, the circulation of the velocity vector of the elements that constitute it, along that potential (it is not another parameter, whose experimental value must be added, as proposed by the standard model of elementary particles). Hence, the electric field appears as the rotational of the velocity field, at each point of the potential medium, and the magnetic field appears as the variation with respect to the velocity field of the potential medium, which is equivalent to the Biot and Savart law. From these considerations, Maxwell’s equations are reached, in particular his second equation which is the non-existence of magnetic monopoles, and the fourth equation which is Ampere’s law, both of which to date are obtained empirically demonstrated theoretically. The electromagnetic field propagation equation is also arrived at, thus this can be considered a demonstration that a potential medium in which eddies exist constitutes a Lorentz-invariant with quantum mechanical properties.

Potential Fluid Biomarkers and a Prediction Model for Better Recognition Between Multiple System Atrophy-Cerebellar Type and Spinocerebellar Ataxia

ObjectiveThis study screened potential fluid biomarkers and developed a prediction model based on the easily obtained information at initial inspection to identify ataxia patients more likely to have multiple system atrophy-cerebellar type (MSA-C).MethodsWe established a retrospective cohort with 125 ataxia patients from southwest China between April 2018 and June 2020. Demographic and laboratory variables obtained at the time of hospital admission were screened using Least Absolute Shrinkage and Selection Operator (LASSO) regression and logistic regression to construct a diagnosis score. The receiver operating characteristic (ROC) and decision curve analyses were performed to assess the accuracy and net benefit of the model. Also, independent validation using 25 additional ataxia patients was carried out to verify the model efficiency. Then the model was translated into a visual and operable web application using the R studio and Shiny package.ResultsFrom 47 indicators, five variables were selected and integrated into the prediction model, including the age of onset (AO), direct bilirubin (DBIL), aspartate aminotransferase (AST), eGFR, and synuclein-alpha. The prediction model exhibited an area under the curve (AUC) of 0.929 for the training cohort and an AUC of 0.917 for the testing cohort. The decision curve analysis (DCA) plot displayed a good net benefit for this model, and external validation confirmed its reliability. The model also was translated into a web application that is freely available to the public.ConclusionThe prediction model that was developed based on laboratory and demographic variables obtained from ataxia patients at admission to the hospital might help improve the ability to differentiate MSA-C from spinocerebellar ataxia clinically.

Integration of geophysical and geomechanical data to understand the depletion of the Marlim field, Campos Basin

Located in the Campos Basin, Brazil, the Marlim field, consists of two turbidite systems deposited during eustatic sea-level variations in the Oligocene/Miocene. The reservoir was discovered in 1985, and its production started to decline in 2002. One of the techniques selected to assist in the recovery of oil from the reservoir was the 4D seismic. However, its interpretation can be complex. In order to help address this issue, the present study proposed an analysis of the depletion of a small field area from 1997 to 2010, combining geophysical (4D seismic) and geomechanical (pore pressure) data through the construction of pore pressure 3D models for both years, which can be subtracted and compared to seismic anomalies. The results obtained were: an average depletion of 0.42 ppg (50.33 kg/m3) of pore pressure gradient in the field; the identification of potential fluid-flow barriers, such as an NW-SE-oriented channel and sealing faults; and the detection of two areas with an expressive presence of 4D seismic anomalies, one of them showing a quite evident difference between pore pressure gradients, suggesting field depletion. The use of very old and noisy seismic data hindered the application of this methodology. Nevertheless, this research demonstrated the relevance of estimating pore pressure in the reservoir and how this geomechanical parameter can be useful in assessing the level of field depletion.

Computational fluid dynamics iteration driven by data

Data-driven approaches have achieved remarkable success in different applications; however, their use in solving partial differential equations (PDEs) has only recently emerged. Herein, we present the potential fluid method (PFM), which uses existing data to nest physical meanings into mathematical iterative processes. The PFM is suitable for partial differential equations, such as computational fluid dynamic problems, including Burgers? equation. PFM can iteratively determine the steady-state space distribution of PDEs. For mathematical reasons, we compare the PFM with the finite difference method (FDM) and give a detailed explanation.

Characterizing damage zones of normal faults using seismic variance in the Wangxuzhuang oilfield, China

We have investigated the distribution and thickness of damage zones for a system of secondary normal faults in the subsurface of the Wangxuzhuang oilfield, China. Based on seismic variance analysis, we find (1) four isolated faults with approximately 2 km length and approximately 200 m damage-zone thickness. The damage zones of these isolated faults reveal a decaying intensity of deformation from the fault core to the protolith, which fits a power-law form [Formula: see text] similar to that observed in the field. (2) A merged fault with approximately 400 m thickness. (3) A bifurcated fault with approximately 400 m thickness and three linked segments. Damage zones that consist of several subsidiary faults are thicker than those of isolated faults. The displacement-length analyses of the four isolated faults suggest the constant-length growth of the limestone in this case. We determine the potential to apply seismic variance to systematically characterize damage zones as potential fluid migration conduits on the basin scale.

Quest for Fluid Flow along the Gloria Fault – First results of R/V Meteor expedition 162

<p>Vast areas of the deep ocean floor are still insufficiently explored with respect to tectonic processes, exchange processes between the lithosphere and the ocean, and potential deep chemosynthetic energy sources for life. Transform faults and fracture zones, which are dominant seafloor morphological features in the abyssal ocean, deserve specific attention in this regard as they provide potential pathways for fluid recycling. One of them is the Gloria Fault, a unique feature in the Central North Atlantic. It has been the source of large magnitude earthquakes (namely the 1941, M8.4, the second largest instrumental earthquake on a fracture zone) and is a special case of a plate boundary, corresponding to the transform reactivation of an old oceanic fracture zone. Seismic refraction has shown an anomalous layer between normal lower crust and uppermost mantle, possibly a 4 km thick layer of hydrated mantle. We present first results of RV Meteor cruise M162 (March-April 2020) dedicated to the groundtruthing of potential fluid emanation sites.</p>

Design and Characterization of a Five-Chamber Constant-Volume Hydraulic Actuator

This paper describes a new design for a constant-fluid-volume, also known as a symmetrical, hydraulic cylinder. In contrast to the two fluid volume chambers of a typical hydraulic cylinder, the constant-fluid-volume cylinder contains five potential fluid chambers. Relative to three and four chamber designs, both previously described in the engineering literature, the five chamber design enables a minimum-diameter solution with a simpler porting implementation. Following a general description of the five-chamber design and its motivation, a five-chamber cylinder prototype is described and presented. Experimental results are presented comparing some behavioral characteristics of the fivechamber cylinder to a double-rod cylinder, and to two variations of single-rod implementations. Finally, a minimum-diameter five-chamber cylinder variant is described, and its geometric characteristics compared to equivalent doublerod and four-chamber cylinder implementations.

Lab scale salt caverns – first results on construction and investigation techniques

Salt caverns from solution mining in bedded or domal saline structures are of increasing importance as temporary subsurface storage space to buffer fluctuating renewables and secure a stable energy supply. To assure the integrity of caverns during operation and long term abandonment, knowledge of geochemical rock–water interactions in the transition zone between cavity and salt rock is necessary. Due to the inaccessibility of cavern walls, a set of lab-based experiments were performed in hand-sized specimens by creating cm-sized cavities using fresh water injection and brine removal. The experimental simulations proved challenging and vacuum pressure tests revealed frequent leakage subsequent to borehole preparation. The samples were cut to expose the formed cavity and its margin. Micro X-ray Fluorescence mapping was employed to obtain information on element distributions and showed a clear separation between Na, Mg and K salt layers. XRF mapping represents a suitable technique to track spatial mineralogical changes related to rock-fluid interaction in salt rocks. Fluorescent liquids were used to visualize potential fluid pathways. First results show that these methods are promising in detecting geochemical changes and their extent and are, thus, useful tools in unravelling geochemical processes related to marginal areas of cavernous structures in salt deposits based on lab-scale simulations.
