Abstract:
In this paper, current Idaho Accelerator Center (IAC) activities based on the exploitation of high energy bremsstrahlung photons generated by linear electron accelerators will be reviewed. These beams are used to induce photonuclear interactions for a wide variety of applications in materials science, activation analysis, medical research, and nuclear technology. Most of the exploited phenomena are governed by the familiar giant dipole resonance cross section in nuclei. By proper target and converter design, optimization of photon and photoneutron production can be achieved, allowing radiation

Abstract This study investigates the influence of the Scandinavian (SCA) pattern on long-lived cold surges over the South China Sea (SCS). The results show that, different from the short-lived ones, the majority of long-lived cold surges over the SCS are preceded by a negative phase of the quasi-stationary SCA pattern in the extratropics, which is characterized as a primary cyclonic center over the Scandinavian Peninsula and two anticyclonic ones over the North Atlantic and central Siberia. This connection is mainly conducted through a continuous amplification of the high pressure anomalies ov

Gamma emitting radionuclides naturally present in the Earth’s crust and the radon exhaled by soil in the atmosphere with its short-lived progeny are two of the main contributors to the environmental gamma dose rate that typically characterizes an outdoor measurement site.

These observations revealed unexpected phenomena in the earliest stages of evolution of massive objects (e.g., non-collimated “short-lived” pulsed ejections in different massive protostars), and provided new insights in the study of the dynamic scena

We present HST-NICMOS images, luminosity functions, and color-magnitude diagrams of two of these: the Quintuplet and Arches clusters.

This paper re-examines Dennis Robertson’s ‘real’ business cycle (RBC) theory outlined in his 1915 A Study in Industrial Fluctuation. Even if, for Robertson, cycles find their origin and respond to oscillations in entrepreneurs’ “rational inducement” to invest, in opposition to RBC models in which every outcome is by construction an equilibrium outcome, Robertson discusses in a traditional way the short-run consequences of such exogenous technological shocks. There are no intertemporal equilibrium phenomena in the sense of the RBC approach; cycle theory is organized, for Robertson, around a Mar

Background: Nowadays, infective endocarditis (IE) is still burdened by a high mortality. In the absence of an adequate prognostic stratification system, it is important to assess new predictors of poor outcomes. The aim of our study is to evaluate which factors were associated with higher mortality in IE patients. Methods: A retrospective cohort study enrolled patients with an IE diagnosis at the Infectious Diseases Clinic of the University ‘G. D’Annunzio’, Chieti, Italy from January 2013 to December 2019. For each patient, demographic, anamnestic and clinical information, embolic phenomena, l

Context. To a first approximation, the microlensing phenomenon is achromatic and great advancements have been achieved with regard to the interpretation of the achromatic signals, leading to the discovery and characterization of well above 100 new exoplanets. At a higher order accuracy in the observations, microlensing has a chromatic component (a color term) that has thus far been explored to a much lesser extent. Aims. Here, we analyze the chromatic microlensing effect of four different physical phenomena, which have the potential to contribute key knowledge of the stellar properties that is

Abstract:
Intermolecular bonding attraction at π-bonded centers is often described as “electrostatically driven” and given quasi-classical rationalization in terms of a “pi hole” depletion region in the electrostatic potential. However, we demonstrate here that such bonding attraction also occurs between closed-shell ions of like charge, thereby yielding locally stable complexes that sharply violate classical electrostatic expectations. Standard DFT and MP2 computational methods are employed to investigate complexation of simple pi-bonded diatomic anions (BO−, CN−) with simple atomic anions (H−, F−) or

The choice of the perspectival center of a stretch of discourse is crucial for the interpretation of certain phenomena such as free indirect discourse. It has been argued that the protagonist that is most prominent compared to competing protagonists gets to be the perspectival center. In this paper we discuss grammatical function and referential expression as prominence-lending cues and their impact on perspective-taking. We take the anchoring of free indirect discourse as the indicator for a shift in perspective as free indirect discourse can only be processed correctly if the reader is able

However, the internal phenomena within its molten pool remain exceptionally challenging to monitor.
