Opium trade and use during the Late Bronze Age: Organic residue analysis of ceramic vessels from the burials of Tel Yehud, Israel

Archaeometry, EarlyView., 2022
Abstract Organic residue analysis was conducted on various vessels from burials at Tel Yehud, Israel. The analyses led to new reliable evidence for the presence of opioid alkaloids and their decomposition products. This research revitalizes a decades‐old discussion on the presence and function of the opium trade across a cultural region of utmost ...

Uniformity in association schemes and coherent configurations: cometric Q-antipodal schemes and linked systems [PDF]

, 2013
Inspired by some intriguing examples, we study uniform association schemes and uniform coherent configurations, including cometric Q-antipodal association schemes. After a review of imprimitivity, we show that an imprimitive association scheme is uniform

Knots with small rational genus [PDF]

, 2012
If K is a rationally null-homologous knot in a 3-manifold M, the rational genus of K is the infimum of -\chi(S)/2p over all embedded orientable surfaces S in the complement of K whose boundary wraps p times around K for some p (hereafter: S is a p ...

The HST/ACS Coma Cluster Survey. VIII. Barred Disk Galaxies In The Core Of The Coma Cluster [PDF]

, 2012
We use high-resolution (similar to 0.'' 1) F814W Advanced Camera for Surveys (ACS) images from the Hubble Space Telescope ACS Treasury survey of the Coma cluster at z similar to 0.02 to study bars in massive disk galaxies (S0s), as well as low-mass dwarf

THE MILLENNIUM GALAXY CATALOGUE: EXPLORING THE COLOR–CONCENTRATION BIMODALITY VIA BULGE–DISK DECOMPOSITION [PDF]

, 2009
We investigate the origin of the galaxy color–concentration bimodality at the bright end of the luminosity function (MB − 5log  h70 < −18 mag) with regard to the bulge–disk nature of galaxies.

Perimeter of sublevel sets in infinite dimensional spaces [PDF]

, 2011
We compare the perimeter measure with the Airault-Malliavin surface measure and we prove that all open convex subsets of abstract Wiener spaces have finite perimeter.

Friction factor decomposition for rough-wall flows: theoretical background and application to open-channel flows

Journal of Fluid Mechanics, 2019
A theoretically based relationship for the Darcy–Weisbach friction factor $f$ for rough-bed open-channel flows is derived and discussed. The derivation procedure is based on the double averaging (in time and space) of the Navier–Stokes equation followed ...

The Millennium Galaxy Catalogue: bulge–disc decomposition of 10 095 nearby galaxies [PDF]

, 2006
We have modelled the light distribution in 10095 galaxies from the Millennium Galaxy Catalogue (MGC), providing publically available structural catalogues for a large, rep- resentative sample of galaxies in the local Universe. Three different models were

Deligne-Beilinson cohomology and abelian link invariants: torsion case [PDF]

, 2009
For the abelian Chern-Simons field theory, we consider the quantum functional integration over the Deligne-Beilinson cohomology classes and present an explicit path-integral non-perturbative computation of the Chern-Simons link invariants in $SO(3)\simeq\

A Novel Method for PolISAR Interpretation of Space Target Structure Based on Component Decomposition and Coherent Feature Extraction

Remote Sensing
Inverse Synthetic Aperture Radar (ISAR) serves as a valuable instrument for surveillance of space targets. There has been a great deal of research on space target identification using ISAR.
