Islamic finance and food commodity trading: is there a chance to hedge against price volatility and enhance food security?

This paper evaluates current food commodity trading from the Shariah point of view, which is particularly relevant for the MENA region. It focuses on futures contracts as the main instrument for grain trading and analyzes the traders' activities. Through a qualitative and multifaceted approach, the paper accumulates and evaluates the suggestions for 15 Shariah-based alternatives to futures by contemporary researchers.

DNA sequence, physics, and promoter function: Analysis of high-throughput data On T7 promoter variants activity.

RNA polymerase/promoter recognition represents a basic problem of molecular biology. Decades-long efforts were made in the area, and yet certain challenges persist. The usage of certain most suitable model subjects is pivotal for the research.

Comparative Analysis of vlhA Promoters.

is an intracellular parasite affecting respiratory tract of poultry that belongs to class Mollicutes. features numerous variable lipoprotein hemagglutinin genes (vlhA) that play a role in immune escape. The vlhA promoters have a set of distinct properties in comparison to promoters of the other genes.

Bacterial promoter prediction: Selection of dynamic and static physical properties of DNA for reliable sequence classification.

Predicting promoter activity of DNA fragment is an important task for computational biology. Approaches using physical properties of DNA to predict bacterial promoters have recently gained a lot of attention. To select an adequate set of physical properties for training a classifier, various characteristics of DNA molecule should be taken into consideration.

Homeostatic regulation in physiological systems: A versatile Ansatz.

A generic modelling formalism is described for homeostatic dynamics in physiological systems. The method is particularly suited where the peripheral, physiological system itself is well-characterised, but the details of the central, regulatory component (the nervous and endocrine systems) have not necessarily been characterised in full detail. The method is applied to temperature regulation in Cardinalis cardinalis, C.
