A description is presented for the isolation and characterization of host phase from Allende C3V chondrite a mass spectrometric study five noble gases in this phase. It though that Xe component may have been produced by spontaneous fission an extinct superheavy element. The resides minor fraction comprising 0.5% meteorite. consists chromite, unknown Cr, Fe-mineral, amorphous carbon. gas components progenitor trapped these minerals when they formed solar nebula.

Abstract Histopathology tissue analysis is considered the gold standard in cancer diagnosis and prognosis. Whole-slide imaging (WSI), i.e., scanning digitization of entire histology slides, are now being adopted across world pathology labs. Trained histopathologists can provide an accurate biopsy specimens based on WSI data. Given dimensionality WSIs increase number potential cases, analyzing these images a time-consuming process. Automated segmentation tumorous helps elevating precision,...

A modular system architecture has been developed to support visual navigation by an autonomous land vehicle. The consists of vision modules performing image processing, three-dimensional shape recovery, and geometric reasoning, as well for planning, navigating, piloting. runs in two distinct modes, bootstrap feedforward. mode requires analysis entire images find model the objects interest scene (e.g., roads). In feedforward (while vehicle is moving), attention focused on small parts field...

The Murchison carbonaceous chondrite contains a new type of xenon component, enriched by up to 50 percent in five the nine stable isotopes, mass numbers 128 132. This comprising 5 x 10(-5) total meteorite, is released at 1200 degrees 1600 C from severely etched mineral fraction, and probably resides some refractory mineral. Krypton shows similar but smaller enrichment isotopes 80 82. Neon helium same interval also are quite anomalous, being highly 22 3. These patterns strongly suggestive...

Abstract A review of the current status computation turbulent impinging jet heat transfer is presented. It starts with a brief introduction to flow and characteristics flows considering simplest geometry: normal impingement single into flat surface. Subsequently, recent computational studies related same geometry The effects different subgrid scale models, boundary conditions, numerical schemes, grid distribution, size domain adopted in various large eddy simulations this configuration are...

This work presents a multi-population dynamic model of microbial electrolysis cell (MEC). The describes the growth and metabolic activity fermentative, electricigenic, methanogenic acetoclastic, hydrogenophilic microorganisms is capable simulating hydrogen production in MEC fed with complex organic matter, such as wastewater. parameters were estimated experimental results obtained continuous flow MECs acetate or synthetic Following successful validation an independent data set, was used to...

Acid-resistant mineral fractions of four chondrites were prepared by dissolving the meteorites in HF-HCl and analyzed for He, Ne, Ar, Kr, Xe mass spectrometry. Although they comprise only 0.1–2.2% meteorites, these residues contained up to 80% total noble gases. High enrichments generally correlated with high Cr contents residues. To determine distribution gas components among individual minerals, several examined more detail techniques such as stepwise heating or selective destruction...

The present contemporary world is propelled by data. Everyone in society makes decisions based on the existing data and proceeds accordingly. Furthermore, all machinery automated using advanced technologies such as Artificial Intelligence (AI), Internet of Things (IoT), Machine Learning (ML), Data Science (DL), which predominantly harness data-driven insights for daily operations. Business organizations, social media, healthcare, big analytics, locality mapping are just a few modern...

In this paper, back propagation is reinvestigated for an efficient evaluation of the gradient in arbitrary interconnections recurrent subsystems. It shown that error has to be back-propagated through adjoint model system and can only obtained after a delay. A faster version, accelerated propagation, eliminates delay, also developed. Various schemes including sensitivity method are studied update weights network using these gradients. Motivated by Lyapunov approach model, predictive its...
