The excitation of surface plasmons with ultra-intense (I ∼ 5 × 1019 W/cm2), high contrast (∼1012) laser pulses on periodically modulated solid targets has been recently demonstrated to produce collimated bunches of energetic electrons along the target surface [Fedeli et al., Phys. Rev. Lett. 116, 015001 (2016)]. Here, we report an extensive experimental and numerical study aimed to a complete char
Speciation is the process that generates biodiversity, but recent empirical findings show that it can also fail, leading to the collapse of two incipient species into one. Here, we elucidate the mechanisms behind speciation collapse using a stochastic individual-based model with explicit genetics. We investigate the impact of two types of environmental disturbance: deteriorated visual conditions,
Svenska EU-parlamentariker har visat att det går att driva på för en aktiv klimat- och miljöpolitik inom EU, skriver Markku Rummukainen, professor i klimatologi, och Roger Hildingsson, statsvetare och forskare i klimatpolitik.

We discuss some aspects of the current status of event generators for small-x DIS. In particular we report on recent results using the CCFM evolution implemented in the SMALLX and CASCADE program concerning the importance of the so-called consistency constraint, and compare with the linked dipole chain model implemented in the LDC program. We point out some potential problems with the resolved vir
Background:Re-ablement is an approach aiming at improve home-care services for older people and to enable and support active engagement in everyday activities. An important responsibility for occupational therapists (OT) is to educate and support home care personnel, by coaching, mentoring and teaching them to work together with the clients to support their management of everyday activities as far
This paper is a summary of the discussion within the Diffractive and Low-x Physics Working Group at the 1999 Durham Collider Workshop of the interpretation of the Tevatron and HERA measurements of inclusive hard diffraction.
