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.

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.

How chaotic is the stadium billiard? A semiclassical analysis

Gregor Tanner
- 21 Apr 1997 - 
TL;DR: In this paper, the authors show that the Gutzwiller trace formula is not applicable for the phase-space dynamics near the bouncing-ball orbits, and they show that a whole region in phase space surrounding the marginal stable family acts, semiclassically, like a stable island with boundaries being explicitly -dependent.

Rapid Electrohydrodynamic Lithography Using Low‐Viscosity Polymers

TL;DR: This study explores a number of low-viscosity glass-forming polymers for their suitability as high-speed materials in electrohydrodynamic (EHD) lithography, and significantly reduces the patterning time compared to earlier approaches.

Minimisation and reduction of 2-, 3- and 4-coverings of elliptic curves

TL;DR: Theorems on the existence of minimal models with the same invariants as the minimal model of the Jacobian elliptic curve are proved and simple algorithms for minimising a given model are provided, valid over general number fields.

Speaker normalization with all-pass transforms.

TL;DR: In this paper, a speaker normalization scheme was proposed by exploiting the fact that frequency domain transformations similar to that inherent in VTLN can be accomplished entirely in the cepstral domain through the use of conformal maps.
