We apply our systematic NLO small x resummation of singlet splitting functions to the scaling violations of structure functions and compare the results with data. We develop various theoretical tools which are needed in order to relate resummed parton distributions to measurable structure functions, and we present results from a variety of fits to HERA data for the structure functions F2 and FL...

We report our first results on comparing the variations of the solar internal rotation with solar activity, as predicted by non-linear solar dynamo modelling, with helioseismic measurements using the SOHO MDI data.

This paper develops a new model of a trade agreement that puts at center stage the competing interests between firms within a sector. Larger firms favor trade liberalization whereas smaller firms favor protection. Lobbying by firms for or against the agreement is modelled as an all-pay auction, thus incorporating the feature that binding contracts over contributions for policies cannot be writt...

The SUMER (Solar Ultraviolet Measurements of Emitted Radiation) instrument on SOHO (Solar and Heliospheric Observatory) provides an opportunity to observe and study the solar transition region with high spatial and spectral resolution. We present new evidence to confirm that the emission from the quiet Sun at 2 × 105 K is dominated by cool loop-like fine structures which cluster across the chro...

Solar eruptions occur when magnetic energy is suddenly converted into heat and kinetic energy by magnetic reconnection in a current sheet (CS). It is often assumed that CSs are too thin to be observable because the electric resistivity in CSs is taken to be very small. In this work, we show the implications for the CS thickness he d estimated from observations of three eruptions by the UVCS and...

Rapidly changing global markets have led to unprecedented growth in small business sectors.1 Firms that fall within the category of ‘small and medium-sized enterprises’ (SMEs) include micro-enterprises employing under 10 people, small enterprises of 11–50 people, and medium-sized enterprises of 51–250 people. This growth, combined with the prevalence of SMEs in the European Union (99% of organi...

Our understanding of fundamental processes in the solar corona has been greatly progressed based on the space observations of SMM, Yohkoh, Compton GRO, SOHO, TRACE, RHESSI, and STEREO. We observe now acoustic waves, MHD oscillations, turbulence-related line broadening, magnetic configurations related to reconnection processes, and radiation from high-energy particles on a routine basis. We revi...

UK small to medium sized enterprises (SMEs) are suffering increasing levels of cybersecurity breaches and are a major point of vulnerability in the supply chain networks in which they participate. A key factor for achieving optimal security levels within supply chains is the management and sharing of cybersecurity information associated with specific metrics. Such information sharing schemes am...

We show that a random flow that depends on space and time generates a mode which is damped and move slower than the coherent f-mode as well as possesses properties which are consistent with the recent SOHO/MDI data (Antia & Basu 1999).

Many methods have been proposed for making use of multiple experts to predict uncertain events such as election outcomes, ranging from simple averaging of individual predictions to complex collaborative structures such as prediction markets or structured group decision making processes. We used a panel of more than 2,000 forecasters to systematically compare the performance of four different co...
