Boundary Conditions for Topological Quantum Field Theories, Anomalies and Projective Modular Functors [PDF]

open access: yes, 2015
We study boundary conditions for extended topological quantum field theories (TQFTs) and their relation to topological anomalies. We introduce the notion of TQFTs with moduli level $m$, and describe extended anomalous theories as natural transformations ...

Adsorption Desulfurization of Liquid Fuel Using a Blend of Date Stones and Walnut Shells by Box–Behnken Design

open access: yesAsia-Pacific Journal of Chemical Engineering, EarlyView.
ABSTRACT A specific microporous KOH/activated‐biochar (K/BC) was produced from a blend of date stones (DS) and walnut shells (WS) and used in the adsorptive desulfurization (ADS) of two types of model fuel DBT/n‐hexane (S‐hex), DBT/cyclohexane (S‐cyclohex).

Removal of Methylene Blue and Congo Red Dyes Using Sustainable and Eco‐Friendly Bioadsorbents: A Review

open access: yesAsia-Pacific Journal of Chemical Engineering, EarlyView.
ABSTRACT The continuous increasing discharge of synthetic dyes into aquatic systems seems to be an important environmental and health risk due to their high toxicity and resistance to biodegradation. Among these dyes, methylene blue (MB) and Congo red (CR) are widely used in textile and industrial applications, necessitating sustainable and efficient ...

The Decidability Frontier for Probabilistic Automata on Infinite Words [PDF]

open access: yes, 2011
We consider probabilistic automata on infinite words with acceptance defined by safety, reachability, B\"uchi, coB\"uchi, and limit-average conditions. We consider quantitative and qualitative decision problems.

Development of a Novel Superhydrophobic Sawdust–Perspex Composite Disc for Efficient Oil–Water Separation

open access: yesAsia-Pacific Journal of Chemical Engineering, EarlyView.
ABSTRACT Water pollution by oil and organic substances causes serious problems that threaten the ecosystem. Superhydrophobic materials represent an effective solution for removing oil from water. The present paper investigates the development of a low‐cost, superhydrophobic composite for oil–water separation.

The complete mitochondrial genome of Dumortiera hirsuta (Sw.) Nees (Dumortieraceae, Marchantiophyta)

open access: yesMitochondrial DNA. Part B. Resources, 2019
Dumortiera hirsuta (Sw.) Nees is one of the large thallose liverworts in order Marchantiales. To compare with mitochondrial genome of Marchantia polymorpha subsp. ruderalis, we completed mitochondrial genome of D.

Finite element analysis of feeding in red and gray squirrels (Sciurus vulgaris and Sciurus carolinensis)

open access: yesThe Anatomical Record, EarlyView.
Abstract Invasive gray squirrels (Sciurus carolinensis) have replaced the native red squirrel (Sciurus vulgaris) across much of Great Britain over the last century. Several factors have been proposed to underlie this replacement, but here we investigated the potential for dietary competition in which gray squirrels have better feeding performance than ...
