Fano's propensity rule in angle-resolved attosecond interferometry

Above-threshold ionization is a corner stone of attsecond science. In this work we extend Fano's propensity rule to two-photon above-threshold ionization and show that the asymmetry between absorption and emission of the second photon predicted by this propensity rule has strong implications for angle-resolved pump-probe experiments and in particular for attosecond photoelectron interferometry.

Opto-optical modulator (OOM) for extreme ultraviolet pulses

There is a profound, almost symbiotic relation between electrons and photons. When light interacts with matter the electrons in the material will start to move and oscillate. When a charged particle, such as an electron, oscillates it will act as a dipole and emit light. We utilize this symbiotic relation and extend the control of light to the extreme ultraviolet (XUV) region using the newly devel

Time-resolved dynamics of thiophene dication - Probing parent molecule survival times and multi-step dissociation processes of cyclic molecules by free-electron-laser experiments combined with theoretical simulations

Thiophene is a cyclic molecule that becomes unstable as a molecular dication. We followed the multi-step dissociation dynamics triggered by soft x-ray FEL pulses from SACLA, core-ionizing the S 2p orbital and creating parent dications by the Auger decay. The time-evolution was probed by optical laser pulsesthat reveal the survival lifetime of the parent dication and the build-up of fragmentation p

X-ray spectroscopy on ultrafast-decaying core-excited atomic ions

Results from the first soft X-ray user experiment at the European XFEL on nonlinear photon-matter interaction will be presented. Angle-resolved electron time-of-flight spectroscopy employed at the AQS (Atomic- like Quantum Systems) endstation of the SQS (Small Quantum Systems) instrument reveals insight into the character of resonances in highly transient, core ionized neon ions, i.e. Ne:+ 1s12s22

Ultrafast ionization and fragmentation dynamics of polycyclic atomatic hydro-carbons by XUV radiation

In the interstellar medium polycyclic aromatic hydrocarbon molecules (PAH) are exposed to strong ionizing radation leading to complex organic photochemistry. We investigated these ultrafast fragmentation reac-tions after ionization of the PAHs phenanthrene, fluorene and pyrene at a wavelength of 30.3 nm using pump probe spectroscopy at a free electron laser. We observe double ionization and afterw

Optimized vs. Standard Automated Peritoneal Dialysis Regimens (OptiStAR) : Study protocol for a randomized controlled crossover trial

Background: It has been estimated that automated peritoneal dialysis (APD) is currently the fastest growing renal replacement therapy in the world. However, in light of the growing number of diabetic patients on peritoneal dialysis (PD), the unwanted glucose absorption during APD remains problematic. Recent results, using an extended 3-pore model of APD, indicated that large reductions in glucose

Influence of user-related parameters on calculated energy use in low-energy school buildings

Literature and experience show that there are large discrepancies between the calculated and measured building energy usages, where user-related parameters are significant factors with regard to energy use in low-energy buildings. Furthermore, the difficulties encountered when quantifying these parameters compound these discrepancies. The main aim of this study was to provide feedback that would h

Foreign demand for agricultural commodities drives virtual carbon exports from Cambodia

Rapid deforestation is a major sustainability challenge, partly as the loss of carbon sinks exacerbates global climate change. In Cambodia, more than 13% of the total land area has been contracted out to foreign and domestic agribusinesses in the form of economic land concessions, causing rapid large-scale land use change and deforestation. Additionally, the distant drivers of local and global env

Under-reported relationship: a comparative study of pharmaceutical industry and patient organisation payment disclosures in the UK (2012-2016)

Objectives To examine the under-reporting of pharmaceutical company payments to patient organisations by donors and recipients. Design Comparative descriptive analysis of payments disclosed on drug company and charity regulator websites. Setting UK. Participants 87 donors (drug companies) and 425 recipients (patient organisations) reporting payments in 2012-2016. Main outcome measures. Number and

Obstetric and intensive-care strategies in a high-risk pregnancy with critical respiratory failure due to COVID-19 : A case report

Background: With the disease burden increasing daily, there is a lack of evidence regarding the impact of COVID-19 in pregnancy. Healthy pregnant women are still not regarded as a susceptible group despite physiological changes that make pregnant women more vulnerable to severe infection. However, high-risk pregnancies may be associated with severe COVID-19 disease with respiratory failure, as out

Pebble-driven planet formation around very low-mass stars and brown dwarfs

We conduct a pebble-driven planet population synthesis study to investigate the formation of planets around very low-mass stars and brown dwarfs in the (sub)stellar mass range between 0.01 M- and 0.1 M-. Based on the extrapolation of numerical simulations of planetesimal formation by the streaming instability, we obtain the characteristic mass of the planetesimals and the initial mass of the proto

The HR 1614 moving group is not a dissolving cluster

Context. The HR 1614 is an overdensity in velocity space and has for a long time been known as an old (2 Gyr) and metal-rich ([Fe=H] +0:2) nearby moving group that has a dissolving open cluster origin. The existence of such old and metal-rich groups in the solar vicinity is quite unexpected since the vast majority of nearby moving groups are known to be young. Aims. In the light of new and signifi

Demo : Millimeter-Wave Massive MIMO Testbed with Hybrid Beamforming

Massive multiple-input multiple-out (MIMO) is vital in millimeter-wave (mmWave) bands to obtain large array gains. However, there are practical challenges, such as high hardware cost and power consumption in such systems. A promising solution to these problems is to adopt a hybrid beamforming architecture. This architecture has a much lower number of transceiver (TRx) chains than the total antenna

Analyzing Hope : The Live Possibility Account

The orthodox definition of hope suffers from an exclusion problem: it is unable to exclude subjects without hope. In fact, the orthodox definition even allows for despair to be falsely classified as hope. This problem suggests two basic desiderata for a successful analysis of hope; it should solve the exclusion problem, and it should have the resources to explain why, in a given situation, a subje

Pebble drift and planetesimal formation in protoplanetary discs with embedded planets

Nearly axisymmetric gaps and rings are commonly observed in protoplanetary discs. The leading theory regarding the origin of these patterns is that they are due to dust trapping at the edges of gas gaps induced by the gravitational torques from embedded planets. If the concentration of solids at the gap edges becomes high enough, it could potentially result in planetesimal formation by the streami

A new equation of state applied to planetary impacts : I. Models of planetary interiors

We present a new analytical equation of state (EOS), which correctly models high pressure theory and fits well to the experimental data of E-Fe, SiO2, Mg2SiO4, and the Earth. The cold part of the EOS is modeled after the Varpoly EOS. The thermal part is based on a new formalism of the Gruneisen parameter, which improves behavior from earlier models and bridges the gap between elasticity and thermo

Trial with academic elite programmes in the comprehensive upper-secondary education in Sweden : a case study

Sweden has a long tradition of comprehensive upper-secondary education. This began in the early 1970s. It culminated in 1994 with all the programmes having a core curriculum that gave general eligibility to higher education. Conservative and liberal governments have introduced several neoliberal school reforms, which the subsequent social democratic government has done little or nothing to change.

Human enteroviral infection impairs autophagy in clonal INS(832/13) cells and human pancreatic islet cells

Aim/hypothesis: Human enteroviral infections are suggested to be associated with type 1 diabetes. However, the mechanism by which enteroviruses can trigger disease remains unknown. The present study aims to investigate the impact of enterovirus on autophagy, a cellular process that regulates beta cell homeostasis, using the clonal beta cell line INS(832/13) and human islet cells as in vitro models
