Il DM 93/2017 sui controlli degli strumenti di metrologia legale

Questo articolo analizza il recente Decreto Ministeriale che disciplina le verifiche periodiche sugli strumenti di misura impiegati in metrologia legale. Vengono discussi gli aspetti giuridici e metrologici, e si mostra come la palese mancanza di competenze metrologiche con cui sono stati redatti gli allegati tecnici rischi seriamente di compromettere e vanificare tutto ciò che di buono è stato introdotto, dal punto di vista specificatamente giuridico, in questo delicato settore

Towards explainable face aging with Generative Adversarial Networks

Generative Adversarial Networks (GAN) are being increasingly used to perform face aging due to their capabilities of automatically generating highly-realistic synthetic images by using an adversarial model often based on Convolutional Neural Networks (CNN). However, GANs currently represent black box models since it is not known how the CNNs store and process the information learned from data. In this paper, we propose the \ufb01rst method that deals with explaining GANs, by introducing a novel qualitative and quantitative analysis of the inner structure of the model. Similarly to analyzing the common genes in two DNA sequences, we analyze the common \ufb01lters in two CNNs. We show that the GANs for face aging partially share their parameters with GANs trained for heterogeneous applications and that the aging transformation can be learned using general purpose image databases and a \ufb01ne-tuning step. Results on public databases con\ufb01rm the validity of our approach, also enabling future studies on similar models

Mutations in the bovine prolactin receptor (PRLR) gene: allele and haplotype frequencies in the Reggiana cattle breed

AbstractProlactin receptor (PRLR) is a member of the cytokine receptor superfamily. PRLR exerts its functions binding three types of ligands (prolactin, placental lactogen and growth hormone) invol..

Optical monitoring of gamma-ray source fields

The three gamma-ray burst source fields GBS1028+46, GBS1205+24, and GBS2252-03 have been monitored for transient optical emission for a combined total of 52 hours. No optical events were seen. The limiting magnitude for the search was M sub V = 15.8 longer and M sub V = 17.0 for 6.0 s or longer

Discovery of near-Earth asteroids by CCD scanning

The found near-Earth asteroid are different objects with peculiar orbits. With the new technique of CCD scanning we entered the domain of the smallest, the fastest, and the closest near-Earth asteroids. The results are presented
