Existential Meanders of Bloody Ignorant Apes : Waiting as the Organising Principle of Existence

“People are bloody ignorant apes” (Beckett 1986, 15), says Estragon pacing back and forth under a bare tree in the first act of Beckett’s Waiting for Godot. Regardless of whether this statement is addressed to his unlucky fellow, Vladimir, sitting right by his side, or whether he just blurts it out without any purpose at all, he inadvertently includes two terms in it. Combined, they provoke a ques

Study of dilepton production in association with leading hadron at RHIC and LHC energies

We demonstrate that current experimental data on γ/Z0 and heavy quarkonium production in pp collisions at RHIC and LHC energies can be described by the color dipole formalism. Three different phenomenological models based on saturation physics are used to estimate the Drell-Yan (DY) dilepton spectra in such processes. In order to further constrain QCD dynamics we suggest to measure the azimuthal c

Electron-ion physics with the LHeC

The Large Hadron Electron Collider (LHeC) project is the proposal to use the existing LHC proton/ion beams and construct a new electron beam line to perform high-energy electron-proton/ion collisions. In this talk, we consider some of the physics topics that could be studied in the electronion mode. In particular, we estimate how much the current nuclear parton distribution fits could be improved

New results for Compton scattering on deuterium : A better determination of the neutron electromagnetic polarizabilities

The electric and magnetic polarizabilities of the proton are now well known, owing to Compton scattering measurements on hydrogen targets; however, the neutron polarizabilities are still relatively uncertain, compared to the proton values. To address this problem, a multiinstitutional collaboration has conducted a program of elastic Compton scattering experiments on deuterium at the MAX IV Laborat

Integration of acousto- and dielectrophoresis allows tumor cell separation and enrichment followed by arraying of target cells toward analysis of circulating tumor cells at the single-cell level

We present an advanced approach for single-cell analysis of circulating tumor cells (CTCs) by integrating an acoustofluidic chip for sample preparation, including simultaneous acoustophoretic separation and enrichment of the separated cells, onto an electroactive microwell array (EMA) for single-cell arraying. The integrated device shows highly efficient cell recovery of target cells (82.5%) and d

The effect of land use change on land surface temperature in the Netherlands

The Netherlands is a small country with a relatively large population which experienced a rapid rate of land use changes from 2000 to 2008 years due to the industrialization and population increase. Land use change is especially related to the urban expansion and open agriculture reduction due to the enhanced economic growth. This research reports an investigation into the application of remote se

Nuclear PDF constraints from p+Pb collisions at the LHC

As the current nuclear PDF analyses are mainly constrained by fixed-target Drell-Yan and deeply inelastic scattering data only the quark nuclear modifications at fairly large x values are in a good control. Inclusive pion production in d+Au collisions at RHIC provides some constraints for gluons but due to the limited kinematic reach of the data the gluon modifications remain uncertain especially

Optimizing intermediate ecosystem services in agriculture using rules based on landscape composition and configuration indices

Important intermediate ecosystem services (ES) such as crop pollination and biological control of pests, which underpin the final ES agricultural yields, are mediated by mobile organisms that depend on availability of habitat and its arrangement in the landscape. It has been suggested that landscape-scale management (LSM) of habitat in a multi-farm setting results in higher provisioning of such ES

Groundwater geochemistry of a nitrate-contaminated agricultural site

Groundwater samples were collected from several soil depths down to 50 m below soil surface to investigate vertical profiles of NO3 − and hydrogeochemical characteristics of the experimental site. The experimental site is located in the Shimabara City, Nagasaki, Japan, where nitrate contamination in groundwater is severe due to intensive agricultural production. A transition zone regarding dissolv

All one-loop scalar vertices in the effective potential approach

Using the one-loop Coleman-Weinberg effective potential, we derive a general analytic expression for all the derivatives of the effective potential with respect to any number of classical scalar fields. The result is valid for a renormalisable theory in four dimensions with any number of scalars, fermions or gauge bosons. This result corresponds to the zero-external momentum contribution to a gene

Interspecific interactions and learning variability jointly drive geographic differences in mate preferences

Co-occurrence of closely related species can cause behavioral interference in mating and increase hybridization risk. Theoretically, this could lead to the evolution of more species-specific mate preferences and sexual signaling traits. Alternatively, females can learn to reject heterospecific males, to avoid male sexual interference from closely related species. Such learned mate discrimination c

Mass spectrometry and site-directed mutagenesis identify several autophosphorylated residues required for the activity of PrkC, a Ser/Thr kinase from Bacillus subtilis

We have shown recently that PrkC, which is involved in developmental processes in Bacillus subtilis, is a Ser/Thr kinase with features of the receptor kinase family of eukaryotic Hanks kinases. In this study, we expressed and purified from Escherichia coli the cytoplasmic domain of PrkC containing the kinase and a short juxtamembrane region. This fragment, which we designate PrkCc, undergoes autop

Using a modified 3D-printer for mapping the magnetic field of RF coils designed for fetal and neonatal imaging

An experimental setup for characterizing the magnetic field of MRI RF coils was proposed and tested. The setup consisted of a specially configured 3D-printer, a network analyzer and a mid-performance desktop PC. The setup was tested on a single loop RF coil, part of a phased array for fetal imaging. Then, the setup was used for determining the magnetic field characteristics of a high-pass birdcage

Methods to improve patient recruitment and retention in stroke trials

Background: The success of randomized-controlled stroke trials is dependent on the recruitment and retention of a sufficient number of patients, but fewer than half of all trials meet their target number of patients. Methods: We performed a search and review of the literature, and conducted a survey and workshop among 56 European stroke trialists, to identify barriers, suggest methods to improve r

A Flexible Link Function for Discrete-Time Duration Models

This paper proposes a discrete-time hazard regression approach based on the relation between hazard rate models and excess over threshold models, which are frequently encountered in extreme value modelling. The proposed duration model employs a flexible link function and incorporates the grouped-duration analogue of the well-known Cox proportional hazards model and the proportional odds model as s
