TLDR
In this paper, a sedimentological core and petrographic characterisation of samples from eleven boreholes from the Lower Carboniferous of Bowland Basin (Northwest England) is presented.
Abstract
Deposits of clastic carbonate-dominated (calciclastic) sedimentary slope systems in the rock record have been identified mostly as linearly-consistent carbonate apron deposits, even though most ancient clastic carbonate slope deposits fit the submarine fan systems better. Calciclastic submarine fans are consequently rarely described and are poorly understood. Subsequently, very little is known especially in mud-dominated calciclastic submarine fan systems. Presented in this study are a sedimentological core and petrographic characterisation of samples from eleven boreholes from the Lower Carboniferous of Bowland Basin (Northwest England) that reveals a >250 m thick calciturbidite complex deposited in a calciclastic submarine fan setting. Seven facies are recognised from core and thin section characterisation and are grouped into three carbonate turbidite sequences. They include: 1) Calciturbidites, comprising mostly of highto low-density, wavy-laminated bioclast-rich facies; 2) low-density densite mudstones which are characterised by planar laminated and unlaminated muddominated facies; and 3) Calcidebrites which are muddy or hyper-concentrated debrisflow deposits occurring as poorly-sorted, chaotic, mud-supported floatstones.

Unified models for active galactic nuclei and quasars

TL;DR: The straw person model (SPM) as mentioned in this paper has been proposed to explain the orientation effects of active galactic nuclei (AGN) and quasars in the line of sight (LOS) images.

Nanocelluloses: A New Family of Nature-Based Materials

TL;DR: This Review assembles the current knowledge on the isolation of microfibrillated cellulose from wood and its application in nanocomposites; the preparation of nanocrystalline cellulose and its use as a reinforcing agent; and the biofabrication of bacterial nanocellulose, as well as its evaluation as a biomaterial for medical implants.

The arcade learning environment: an evaluation platform for general agents

TL;DR: The Arcade Learning Environment (ALE) as discussed by the authors is a platform for evaluating the development of general, domain-independent AI technology, which provides an interface to hundreds of Atari 2600 game environments, each one different, interesting, and designed to be a challenge for human players.

A review of the features and analyses of the solid electrolyte interphase in Li-ion batteries

TL;DR: The solid electrolyte interphase (SEI) is a protecting layer formed on the negative electrode of Li-ion batteries as a result of electrolyte decomposition, mainly during the first cycle as discussed by the authors.

Periodic-orbit theory of universal level correlations in quantum chaos

TL;DR: In this article, Gutzwiller's semiclassical periodic-orbit theory is used to demonstrate universal behavior of the two-point correlator of the density of levels for quantum systems whose classical limit is fully chaotic.

Continuum simulation of the discharge of the granular silo: a validation test for the μ(I) visco-plastic flow law.

TL;DR: The general ability of the continuum model to reproduce qualitatively the granular behavior is found to be very encouraging, however, potential problems involving the systems size, the configuration and “non-local” effects are suggested.

Different features of the MHC class I heterodimer have evolved at different rates. Chicken B-F and beta 2-microglobulin sequences reveal invariant surface residues.

TL;DR: Both chicken alpha 1 and alpha 2 domains resemble mammalian classical class I molecules and the MHC-encoded nonclassical molecules more than CD1 or the class I-like FcR; the chicken alpha 3 domain is equally homologous to all alpha 3 domains, to beta 2m and to class II beta 2 domains.

TL;DR: In this paper, an analytic extrapolation of sub-threshold reaction amplitudes computed in chiral perturbation theory, where the constraints set by electromagnetic-gauge invariance, causality and unitarity are used to stabilize the extrapolation.
