The MEthane Remote sensing Lidar missioN (MERLIN) aims at demonstrating the spaceborne active measurement of atmospheric methane, a potent greenhouse gas, based on an Integrated Path Differential Absorption (IPDA) nadir-viewing LIght Detecting and Ranging (Lidar) instrument. MERLIN is a joint French and German space mission, with a launch currently scheduled for the timeframe 2021/22. The German S

Many automated gating algorithms for flow cytometry data are based on the concept of unimodal cell populations. However, in this article, we show that criteria previously used to make decisions on unimodality cannot adequately distinguish unimodal from bimodal densities. We show that dip and bandwidth tests for unimodality, taken from the statistics literature, can do this with consistent and low

The optical properties of monolayer molybdenum disulfide (MoS2)/Ag nanoparticle (NP) hybrids and their application to surface catalytic reactions were studied by transmission, photoluminescence (PL) and Raman spectroscopies. The local surface plasmon resonance (LSPR) of Ag nanoparticles was tuned to better match the exciton energy of monolayer MoS2. The PL of the hybrids was enhanced by more than

The current issue of Journal of Intercultural and Interdisciplinary Archaeology is mainly dedicated to the various aspects of Renenutet/Isis Thermouthis, but also snake-like deities, their iconography and associated apotropaia. This paper will explore three main topics associated with this topic within the sandstone quarry of Gebel el Silsila: 1) Graeco-Roman anguiform pictorial representations, 2

Gebel el-Silsila displays an astounding concentration of incised illustrations, of which anthropomorphic figures are frequent motifs. These figures were produced over several millennia; from prehistoric petroglyphs to pictorial graffiti of dynastic periods and throughout into Roman days.

Gebel el-Silsila (Mountain of Chain) is located between Kom Ombo and Edfu on both banks of the Nile where it reaches its narrowest point. The site is generally known for its many Pharaonic cenotaphs, stelae and the speos of Horemheb, but it was once also the world’s largest quarry. As such it was renowned for its high quality sandstone, and the stone was extracted and transported to all overUpper Gebel el Silsila (Mountain of Chain) is located between Kom Ombo and Edfu on both banks of the Nile where it reaches its narrowest point.

We report a measurement of e+e- pairs from semileptonic heavy-flavor decays in p+p collisions at sNN=200 GeV. The e+e- pair yield from bb and cc is separated by exploiting a double differential fit done simultaneously in dielectron invariant mass and pT. We used three different event generators, pythia, mc@nlo, and powheg, to simulate the e+e- spectra from cc and bb production. The data can be wel

The list of Egyptian deities attested in Greek and demotic inscriptions in the sandstone quarries of Gebel el-Silsila comprises Amun, Horus, Hathor, Isis, Khnum, Montu, Pachimesen, and Shaï.

Though long admired for its Pharaonic stelae, shrines, and rock-cut temple, the grand ancient site of Gebel el Silsila remains fairly unknown withinmainstream archaeology. A general idea is that the site operated merely as a sandstone quarry, but few are aware of its rich archaeology thatincorporates evidence of millennia of human activity and cultural features that meet seven of UNESCO’s ten outs

The current paper is aimed as a primary publication of eight scarabs assembled by the Swedish-Egyptian excavation team between 2015 and 2016, found in private tombs of the Eighteenth Dynasty necropolis at Gebel el-Silsila East. Each entry includes information about field number, dimensions, material, description, inscription, and dating if possible. Typology conclusions are based on comparisons to

Observations of coral-reef fish larvae have revealed remarkably consistent orientation behaviour while swimming offshore, requiring large-scale orientation cues. However, the mechanisms underlying this behaviour are still being investigated. One potential large-scale cue for orientation is the Earth's geomagnetic field. Here, we examined the effect of magnetic field manipulations on the orientatio

Scallops possess a visual system comprising up to 200 eyes, each containing a concave mirror rather than a lens to focus light. The hierarchical organization of the multilayered mirror is controlled for image formation, from the component guanine crystals at the nanoscale to the complex three-dimensional morphology at the millimeter level. The layered structure of the mirror is tuned to reflect th

B cells produce antibodies, key effector molecules in health and disease. They mature their properties, including their affinity for antigen, through hypermutation events; processes that involve, e.g., base substitution, codon insertion and deletion, often in association with an isotype switch. Investigations of antibody evolution define modes whereby particular antibody responses are able to form

Aims. We aim to study the variability properties of bright hard X-ray selected active galactic nuclei (AGN) in the redshift range between 0.3 and 1.6 detected in the Chandra Deep Field South (XMM-CDFS) by a long (∼3 Ms) XMM observation. Methods. Taking advantage of the good count statistics in the XMM CDFS, we search for flux and spectral variability using the hardness ratio (HR) techniques. We al
