Geo-neutrinos [PDF]

open access: yesProgress in Particle and Nuclear Physics, 2013
We review a new interdisciplinary field between Geology and Physics: the study of the Earth's geo-neutrino flux. We describe competing models for the composition of the Earth, present geological insights into the make up of the continental and oceanic crust, those parts of the Earth that concentrate Th and U, the heat producing elements, and provide ...

Orbit Design and Trajectory Analysis of satellite in Low Earth Orbit [PDF]

open access: yesINCAS Bulletin, 2021
An Attitude control system for a satellite in low earth orbit is designed in this project. As a reference, CARTOSAT-2 is selected to design the AOCS. CARTOSAT-2 is located in LEO so it suits the needs of the projects.

Non solo dal cielo. "The Winegrover”

open access: yesGEOmedia, 2021
We present an approach in which, by exploiting the collaboration of an aerial drone and our autonomous amphibious Rover, data layers containing information detectable only from the ground can be added to the aerial maps detected by an aerial drone.

Development and Validation of a Prognosis-Prediction Signature for Patients with Lung Adenocarcinoma Based on 11 Telomere-Related Genes

open access: yesFrontiers in Bioscience-Landmark, 2023
Background: The occurrence and progression of lung cancer are correlated with telomeres and telomerase. Telomere length is reduced in the majority of tumors, including lung cancers.

Screening and Identification of Key Genes in Hepatitis B Virus-Related Hepatocellular Carcinoma Through an Integrated Bioinformatics Approach

open access: yesAsian Pacific Journal of Cancer Biology, 2022
Objective: Primary liver cancer is one of the main causes of cancer mortality globally, with hepatocellular carcinoma (HCC) being the most frequent type. Chronic hepatitis B virus (HBV) infection is leading cause of HCC.

Assessing the effects of different land-use/land-cover input datasets on modelling and mapping terrestrial ecosystem services - Case study Terceira Island (Azores, Portugal) [PDF]

open access: yesOne Ecosystem, 2021
Modelling ecosystem services (ES) has become a new standard for the quantification and assessment of various ES. Multiple ES model applications are available that spatially estimate ES supply on the basis of land-use/land-cover (LULC) input data.

Observation of geo-neutrinos [PDF]

open access: yesPhysics Letters B, 2010
Geo-neutrinos, electron anti-neutrinos produced in beta decays of naturally occurring radioactive isotopes in the Earth, are a unique direct probe of our planet's interior. We report the first observation at more than 3$ $ C.L. of geo-neutrinos, performed with the Borexino detector at Laboratori Nazionali del Gran Sasso.
