The Bayesian model presented in this article is the first attempt to produce a chronological framework for Iron Age Levant, using radiocarbon dating alone. derives from 339 determinations on 142 samples taken 38 strata at 18 sites. proposes six ceramic phases and transitions which cover c . 400 years, between late twelfth mid eighth centuries BC. It furnishes us with new scientific backbone history of Levant. supported by an online supplement can be found...
We studied simultaneously the 4He(e,e'p), 4He(e,e'pp), and 4He(e,e'pn) reactions at Q^2=2 [GeV/c]2 x_B>1, for a (e,e'p) missing-momentum range of 400 to 830 MeV/c. The knocked-out proton was detected in coincidence with or neutron recoiling almost back missing momentum, leaving residual A=2 system low excitation energy. These data were used identify two-nucleon short-range correlated pairs deduce their isospin structure as function momentum region where nucleon-nucleon force is expected...
We studied the 12C(p,2p+n) reaction at beam momenta of 5.9, 8.0, and 9.0 GeV/c. For quasielastic (p,2p) events p(f), momentum knocked-out proton before reaction, was compared (event by event) with p(n), coincident neutron momentum. |p(n)|>k(F)=0.220 GeV/c (the Fermi momentum) a strong back-to-back directional correlation between p(f) p(n) observed, indicative short-range n-p correlations. From we constructed distributions c.m. relative motion in longitudinal direction for correlated pairs....
Significance Scholars debate whether the first major phase of compilation biblical texts took place before or after destruction Jerusalem in 586 BCE. Proliferation literacy is considered a precondition for creation such texts. Ancient inscriptions provide important evidence proliferation literacy. This paper focuses on 16 ink found desert fortress Arad, written ca . 600 By using novel image processing and machine learning algorithms we deduce presence at least six authors this corpus....
Summary We present a full‐sequence radiocarbon‐based chronological system for the Iron Age in Levant, anchored on dating of ten destruction layers years 1130–730 BC. establish sequence using two methods – ‘uncalibrated weighted average’ and Bayesian modelling. Utilizing four tools combination radiocarbon measurements, field stratigraphy, pottery typology ancient Near Eastern historical records facilitates solutions to problems that are far beyond resolving power 14 C alone. The results shed...
Results of electron-induced one- and two-nucleon hard knockout reactions, $A(e,e'p)$ $A(e,e'pN)$, in kinematics sensitive to nuclear short-range correlations, are studied using the contact formalism. A relation between spectral function contacts is derived used analyze dependence data on initial energy momentum knocked-out proton. The ratio number emitted proton-proton pairs proton-neutron shown depend predominantly a single contacts. This expected present deep minima plane, associated with...
This article is a rejoinder to recent paper in this journal by van der Plicht et al. (2009) who use radiocarbon determinations from several sites Israel, Italy, Spain, and Tunisia advocate High Chronology system for the entire Mediterranean Basin. We contend that they reached mistaken conclusions due problematic selection of data. argue reliable way provide absolute dates Iron Age central western employing combination well-identified Greek pottery found well-stratified radiometric results...
The article proposes a radiocarbon-based dating scheme for the entire Aegean ceramic sequence, from Late Helladic IIIB2 to Middle Geometric II, with implications Cypriot IIC Cypro-Geometric III phases. It accomplishes this by exercising “chronology proxy”—that is, turning radiocarbon-dated strata in Levant that produced Aegean, Aegean-related, and corresponding pottery items represent most of IIIB—Middle sequence. describes these contexts above-mentioned found them, then reports results...
Recently, the use of 4He particles in cancer radiotherapy has been reconsidered as they potentially represent a good compromise between protons and 12C ions. The first step to achieve this goal is development dedicated treatment planning system, for which basic physics information such characterization beam lateral scattering fragmentation cross sections are required. In present work, attenuation primary build-up secondary charged fragments at various depths water polymethyl methacrylate...

The article deals with the 46 14C determinations from Khirbet en-Nahas, described as largest Iron Age copper-smelting site in southern Levant. It is suggested that production at en-Nahas: (1) commenced early I (after collapse of Egypto-Canaanite system) an outcome decline Cypriot copper-trade Levant; (2) peaked thefirst half 9th century, possibly a result need for considerable amounts bronze by vast and powerful armies rising territorial kingdoms (3) ended late century BCE, probably...
Mazar and Bronk Ramsey (2008) recently proposed that the Iron I/IIA transition in Levant took place during first half of 10th century. In part this article, we challenge their method conclusions. We argue against inclusion charcoal model, which could lead to an “old wood effect.” also dealing with a date, all available data must be taken into consideration. second propose Bayesian Model I for transition, is based on 2 sets data—for periods immediately before after transition. Our along other...
We demonstrate that for small values of momentum transfer ${Q}^{2}$ the in-medium change ${G}_{E}/{G}_{M}$ form factor ratio a bound neutron is dominated by in electric charge radius and predict within stated assumptions will increase relative to free result. This effect act predicted cross section recoil polarization process $^{4}\mathrm{He}(\stackrel{\ensuremath{\rightarrow}}{e},{e}^{\ensuremath{'}}\stackrel{\ensuremath{\rightarrow}}{n})^{3}\mathrm{He}$. contrast with medium modification...
The discipline of First Temple Period epigraphy (the study writing) relies heavily on manually-drawn facsimiles (black and white images) ancient inscriptions. This practice may unintentionally mix up documentation interpretation. As an alternative, this article surveys the performance several existing binarization techniques. quality their results is found to be inadequate for our purpose. A new method automatically creating a facsimile then suggested. technique based connected-component...
A partial-wave analysis of recent low-energy pion-absorption data on a diproton ($^{1}S_{0}$) in $^{3}\mathrm{He}$ is supplemented by proton-neutron final-state-interaction phase shifts and mixing parameters, yielding model-independent determination the absorption amplitude. Several possible amplitudes describe existing angular distribution, but these can essentially be distinguished polarization measurement.
We study the ratio R identical with muG_{E}(Q2)/G_{M}(Q2) of proton at very small values Q2. Radii commonly associated these form factors are not moments charge or magnetization densities. show that factor F2 is correctly interpretable as two-dimensional Fourier transformation a density. A relationship between measurable and true densities derived used to density extends further than density, in contrast expectations based on measured reduction Q2 increases.
We report on new p(e,e′p)π∘ measurements at the Δ+(1232) resonance low momentum transfer region, where mesonic cloud dynamics is predicted to be dominant and rapidly changing, offering a test bed for chiral effective field theory calculations. The data explore Q2 dependence of resonant quadrupole amplitudes first time indicate that Electric Coulomb converge as Q2→0. amplitude have been extended lowest ever reached, suggest more than half its magnitude attributed in this region. disagree with...
This article discusses methodological issues related to the radiocarbon dating of Khirbet Qeiyafa, mainly question whether site should be dated solely according samples retrieved there or as part a regional sequence stratigraphically based ceramic typology phases. For latter, we deploy large number 14 C determinations now available for several sites in Shephelah, which are located close proximity each other, order establish Bayesian model absolute chronology Iron I–IIA phases region. We...
Megiddo, with its tight stratigraphy and well-controlled ceramic typology, yielded more than half of the radiocarbon determinations for time span Middle Bronze II to Iron I in southern Levant. Here we present two models this entire sequence, focusing on Late Age—1) Megiddo; 2) Megiddo Beth-Shean—adding a third model sites which provide results relevant III/Late transition. We then discuss impact material culture history particular Levant (and eastern Mediterranean) general.
Based on averaging four radiocarbon determinations, Garfinkel and Ganor (2009) have dated the Iron Age layer at Khirbet Qeiyafa to ca. 1025–975 BCE declared demise of Low Chronology for strata in Levant. We show that case is not a legitimate procedure. The five available measurements represent life-span site rather than single event. With data, all one can say activity started 1050 ended sometime during 10th century, no later 915 BCE. 14C determinations line up with large number from late I...
A recent study shows that multispectral (MS) imaging can improve the legibility of ostraca. Several examples Iron Age ostraca unearthed over twenty years ago in Israel (Ḥorvat ʿUza and Ḥorvat Radum) are presented, showing how new images taken with an MS system reading inscriptions have significantly faded time. The article provides instructions for constructing a simple low-cost yields comparable results to commercial systems.
