The years of ‘happy scaling’ are over and the fundamental challenges that the semiconductor industry faces, at both technology and device level, will impinge deeply upon the design of future integrated circuits and systems. This paper provides an introduction to these challenges and gives an overview of the Grid infrastructure that will be developed as part of a recently funded EPSRC pilot project to address them, and we hope, which will revolutionise the electronics design industry.

Experimental and theoretical studies have shown the importance of stochastic processes in genetic regulatory networks and cellular processes. Cellular networks and genetic circuits often involve small numbers of key proteins such as transcriptional factors and signaling proteins. In recent years stochastic models have been used successfully for studying noise in biological pathways, and stochastic modelling of biological systems has become a very important research field in computational biology. One of the challenge problems in this field is the reduction of the huge computing time in stochastic simulations. Based on the system of the mitogen-activated protein kinase cascade that is activated by epidermal growth factor, this work give a parallel implementation by using OpenMP and parallelism across the simulation. Special attention is paid to the independence of the generated random numbers in parallel computing, that is a key criterion for the success of stochastic simulations. Numerical results indicate that parallel computers can be used as an efficient tool for simulating the dynamics of large-scale genetic regulatory networks and cellular processes.

We present an algorithm that allows two users to establish a symmetric cryptographic key by incorporating the most important features of the wireless channel in vehicle-to-vehicle (V2V) communication. Non-reciprocity compensation is combined with turbo codes (TCs) for error reconciliation purposes. For fair comparisons, the indexing technique is applied in conjunction with the non-reciprocity compensation technique. A series of simulations are run to calculate key performance indicators (KPIs). High entropy values are obtained throughout all rounds of simulation during the key extraction process. Furthermore, simulation results indicate a significant improvement in bit mismatch rate (BMR) and key generation rate (KGR) when TCs are used. Increasing the number of iterations in the TC can significantly improve the Bit Error Rate (BER), thus generating more symmetric keys. The key generation rate was reported high ranging from 17 to 19 for the 256-bit symmetric keys per minute with TCs, while it is ranging from 2 to 5 when compared with a sample indexing technique published in the public domain. Finally, simulations proved also improvements for different key lengths as part of the error reconciliation process when TCs are used with an almost regular permutation (ARP) instead of a random permutation.

This chapter discusses how participatory methodologies (specifically, a critical participatory action research cycle involving planning, action, observation, and reflection) were developed in an online research project on critical English language education in a context of protracted crisis, in the Gaza Strip (Palestine). The impediments to research imposed by the COVID-19 global pandemic are nothing new to the Gaza Strip, which has been under blockade since 2007, impacting Gazans’ mental and physical wellbeing, affecting Gazan academics participation in international networks and collaborative partnerships and obstructing the flow of knowledge, books and teaching materials. Critical, creative and localised pedagogies enabled UK-based researchers and pre-service, secondary school English teachers based in the Gaza Strip to jointly develop, trial and evaluate teaching materials and lesson plans.

This chapter provides an outline of how ethnic diversity affects political participation in Britain. It focuses on how ethnicity related barriers hinder political participation, before concluding that the political participation of ethnic and racial minorities is related to their political rights and the scale of their political representation. Ethnicity is a term that describes the real or imagined features of group membership, typically in terms of one or other combination of language, collective memory, culture, ritual, dress and religion, amongst other features. The necessity of forming such ‘ethnic’ trade unions was due to the lack of support from the British trade union movement. Ethnic minorities were also influential inside the Labour Party, exemplified by the ten-year ‘Black Sections’ movement that commenced in 1983 and was the most important campaign for representation and self-organisation within the party. The formal political participation of ethnic minorities by means of voting is, inevitably, premised upon their levels of electoral registration
