Abstract

The High-Energy Particle Detector (HEPD-02) is one of the scientific payloads of the China Seismo-Electromagnetic Satellite (CSES-02). The HEPD-02’s main purpose is to characterize the particle environment in the Earth’s vicinity, identifying sudden changes in the fluxes and correlating them with solar and terrestrial phenomena. Additionally, HEPD-02 also has capabilities in detecting Gamma-Ray Bursts. At the core of HEPD-02, a tower of scintillation counters made of plastic and LYSO crystals is able to recognize electrons in the range between 3 and 100 MeV, protons and nuclei between 30 and 200 MeV/n. Plastic scintillators covering the calorimeter on five sides allow to reject particles entering from the top and not completely absorbed within its volume. In this work, the design of the HEPD-02 is reviewed in comparison to its predecessor, HEPD-01, highlighting the innovations of the new design. The design of each scintillation counter type has been fully validated through a campaign of prototype realization, testing, and characterization. The production of the scintillation counters, including the PMT selection process, is also discussed. Finally, the performance of the counters is compared with simulations, showing an agreement of within 20% with the expected performance, thereby meeting expectations.

Abstract

Abstract Earth’s atmosphere, whose ionization stability plays a fundamental role for the evolution and endurance of life, is exposed to the effect of cosmic explosions producing high energy Gamma-ray-bursts. Being able to abruptly increase the atmospheric ionization, they might deplete stratospheric ozone on a global scale. During the last decades, an average of more than one Gamma-ray-burst per day were recorded. Nevertheless, measurable effects on the ionosphere were rarely observed, in any case on its bottom-side (from about 60 km up to about 350 km of altitude). Here, we report evidence of an intense top-side (about 500 km) ionospheric perturbation induced by significant sudden ionospheric disturbance, and a large variation of the ionospheric electric field at 500 km, which are both correlated with the October 9, 2022 Gamma-ray-burst (GRB221009A).

Abstract

We provide new evidence on the impact of peer effects on the schooling decisions of teenagers. In November 1980 a major earthquake hit Southern Italy. In the aftermath, young men from certain towns were exempted from compulsory military service. We show that the exemption raised high school graduation rates of boys by more than 2 percentage points by comparing high school graduation rates of young exempt men and older not exempt men from the least damaged areas and men of the same age groups from nearby towns that were not hit by the quake. Similar comparisons show that graduation rates of young women in the affected areas rose by about 2 percentage points. Since in Italy women are not subject to drafting, we interpret these findings as evidence of social effects of the decision of teenage boys of staying longer in school on that of teenage girls. Our estimates suggest that an increase of 1 percentage point of male graduation rates raises female probability of completing high school by about 0.7-0.8 percentage points. A series of robustness checks, including comparisons across different age groups and with different definitions of the comparison areas, suggest that the rise was due to the earthquake-related exemption, rather than other factors.

Abstract

The labour market status of many non-working persons is at the boundary between unemployment and inactivity. Like the unemployed, they seek and are available for work; unlike them, their last search action was not recent enough to meet the ILO definition of unemployment. In this paper we examine by non-parametric tests how the transition probabilities of these out-of-the-labour-force job seekers differ from those of the unemployed as well as the other non-participants. First, using data from the European Community Household Panel, we show that in most EU countries these job seekers constitute a distinct labour market state. Second, we rely on information only available in the Italian Labour Force Survey to derive a measure of search intensity which we use to break down the out-of-the-labour-force job seekers. On the basis of their transition probabilities, the most active are indistinguishable from the unemployed.
