Study queStion Is methylphenidate beneficial or harmful for the treatment of attention-deficit/hyperactivity disorder (ADHD) in children and adolescents? MethodS Electronic databases were searched up to February 2015 for parallel and crossover randomised clinical trials comparing methylphenidate with placebo or no intervention in children and adolescents with ADHD. Meta-analyses and trial seque...
Correspondence: rizwan Dewji Imperial College School of Medicine, Imperial College London, London, SW7 2AZ, UK tel +44 020 7589 5111 Email [email protected] Dear Editor In recent times, there has been a declining trend in bedside teaching as part of the medical teaching curriculum. It is clear that this fundamental issue presents a potential barrier to the development of both curren...
EDITOR: Venous air embolism (VAE), the entrainment of air into the venous system during surgery, is a well-known complication of surgery in the sitting position. VAE can also occur in the prone position but is under suspected and under reported. There is only one report of VAE occurring in three separate patients in the prone position. There are no reports published in the European literature. ...
In this article we consider two classes of static defensive resource allocation problems, these are, the static "target-value based" weapon target allocation and the static "asset-value based" weapon allocation problem. It is shown that the target-value based problem can be recast, (using indicator functions), into an instantiation of the so-called transportation problem. The transportation pro...

The quantum phase description of Noh, Fougères and Mandel (NFM) leads to a two-mode theory of phase in the strong local oscillator limit. We show that the explicit form of the eigenstates of the sine and the cosine phase operators in two-mode Fock space can be constructed. This brings great convenience to the NFM quantum phase approach. Recently, phase operators and phase measurements in quantu...
Temperature and Fermi energy dependent exciton eigenenergies of monolayer molybdenum disulfide (MoS2) are calculated using an atomistic model. These exciton eigen-energies are used as the resonance frequencies of a hybrid Lorentz-Drude-Gaussian model, in which oscillation strengths and damping coefficients are obtained from the experimental results for the differential transmission and reflecti...
Over the past decade, the gut-associated lymphocytes have been shown to play a critical role in the early pathogenesis of HIV infection. Because of constant exposure to foreign antigens, the gut contains an abundance of activated effector memory CD4 T cells that express CCR5 and are highly susceptible to HIV infection [1]. Primary HIV infections and simian immunodeficiency virus (SIV) infection...
