A history of high-power laser research and development in the United Kingdom
The first demonstration of laser action in ruby was made in 1960 by T. H. Maiman of Hughes Research Laboratories, USA. Many laboratories worldwide began the search for lasers using different materials, operating at different wavelengths. In the UK, academia, industry and the central laboratories took up the challenge from the earliest days to develop these systems for a broad range of applications. This historical review looks at the contribution the UK has made to the advancement of the technology, the development of systems and components and their exploitation over the last 60 years

Sub-Telomere Directed Gene Expression during Initiation of Invasive Aspergillosis
Aspergillus fumigatus is a common mould whose spores are a
component of the normal airborne flora. Immune dysfunction permits developmental
growth of inhaled spores in the human lung causing aspergillosis, a significant
threat to human health in the form of allergic, and life-threatening invasive
infections. The success of A. fumigatus as a pathogen is unique
among close phylogenetic relatives and is poorly characterised at the molecular
level. Recent genome sequencing of several Aspergillus species
provides an exceptional opportunity to analyse fungal virulence attributes
within a genomic and evolutionary context. To identify genes preferentially
expressed during adaptation to the mammalian host niche, we generated multiple
gene expression profiles from minute samplings of A. fumigatus
germlings during initiation of murine infection. They reveal a highly
co-ordinated A. fumigatus gene expression programme, governing
metabolic and physiological adaptation, which allows the organism to prosper
within the mammalian niche. As functions of phylogenetic conservation and
genetic locus, 28% and 30%, respectively, of the
A. fumigatus subtelomeric and lineage-specific gene
repertoires are induced relative to laboratory culture, and physically clustered
genes including loci directing pseurotin, gliotoxin and siderophore biosyntheses
are a prominent feature. Locationally biased A. fumigatus gene
expression is not prompted by in vitro iron limitation, acid,
alkaline, anaerobic or oxidative stress. However, subtelomeric gene expression
is favoured following ex vivo neutrophil exposure and in
comparative analyses of richly and poorly nourished laboratory cultured
germlings. We found remarkable concordance between the A.
fumigatus host-adaptation transcriptome and those resulting from
in vitro iron depletion, alkaline shift, nitrogen
starvation and loss of the methyltransferase LaeA. This first transcriptional
snapshot of a fungal genome during initiation of mammalian infection provides
the global perspective required to direct much-needed diagnostic and therapeutic
strategies and reveals genome organisation and subtelomeric diversity as
potential driving forces in the evolution of pathogenicity in the genus

The CLoud–Aerosol–Radiation interaction and forcing: year 2017 (CLARIFY-2017) measurement campaign
The representations of clouds, aerosols, and cloud–aerosol–radiation impacts remain some of the largest uncertainties in climate change, limiting our ability to accurately reconstruct past climate and predict future climate. The south-east Atlantic is a region where high atmospheric aerosol loadings and semi-permanent stratocumulus clouds are co-located, providing an optimum region for studying the full range of aerosol–radiation and aerosol–cloud interactions and their perturbations of the Earth’s radiation budget. While satellite measurements have provided some useful insights into aerosol–radiation and aerosol–cloud interactions over the region, these observations do not have the spatial and temporal resolution, nor the required level of precision to allow for a process-level assessment. Detailed measurements from high spatial and temporal resolution airborne atmospheric measurements in the region are very sparse, limiting their use in assessing the performance of aerosol modelling in numerical weather prediction and climate models. CLARIFY-2017 was a major consortium programme consisting of five principal UK universities with project partners from the UK Met Office and European- and USA-based universities and research centres involved in the complementary ORACLES, LASIC, and AEROCLO-sA projects. The aims of CLARIFY-2017 were fourfold: (1) to improve the representation and reduce uncertainty in model estimates of the direct, semi-direct, and indirect radiative effect of absorbing biomass burning aerosols; (2) to improve our knowledge and representation of the processes determining stratocumulus cloud microphysical and radiative properties and their transition to cumulus regimes; (3) to challenge, validate, and improve satellite retrievals of cloud and aerosol properties and their radiative impacts; (4) to improve the impacts of aerosols in weather and climate numerical models. This paper describes the modelling and measurement strategies central to the CLARIFY-2017 deployment of the FAAM BAe146 instrumented aircraft campaign, summarizes the flight objectives and flight patterns, and highlights some key results from our initial analyses
Empiric treatment against invasive fungal diseases in febrile neutropenic patients: a systematic review and network meta-analysis
Energy Resolution Performance of the CMS Electromagnetic Calorimeter
The energy resolution performance of the CMS lead tungstate crystal electromagnetic calorimeter is presented. Measurements were made with an electron beam using a fully equipped supermodule of the calorimeter barrel. Results are given both for electrons incident on the centre of crystals and for electrons distributed uniformly over the calorimeter surface. The electron energy is reconstructed in matrices of 3 times 3 or 5 times 5 crystals centred on the crystal containing the maximum energy. Corrections for variations in the shower containment are applied in the case of uniform incidence. The resolution measured is consistent with the design goals
