- Two process concepts for integration of novel gate stacks with epitaxial high-K dielectrics and metal gate electrodes are presented. A "gate first" process based on a planar gate stack on ultra thin SOI material has been used for successful fabrication of MOSFETs with TiN/Gd2O3 gate stack. Furthermore MOSFETs with W/Gd2O3 gate stack have been fabricated with a replacement gate process. This is the first successful attempt to integrate crystalline high-K dielectrics into a "gentle" damascene metal gate process in order to reduce process induced oxide damages.

- In this work we report on methods to introduce crystalline rare-earth (RE) oxides with high (k > 3.9) dielectric constants (high-k) in a CMOS process flow. Key process steps compatible with crystalline praseodymium oxide (Pr2O3) high-k gate dielectric have been developed and evaluated in metal-oxide-semiconductor (MOS) structures and n-MOS transistors fabricated in an adapted conventional bulk process. From capacitance-voltage measurements a dielectric constant of k = 36 has been calculated. Furthermore an alternative process sequence suitable for the introduction of high-k material into silicon on insulator (SOI) MOS-field-effect-transistors (MOSFET) is presented. The feasibility of this process is shown by realization of n- and p-MOSFETs with standard SiO2 gate dielectric as demonstrator. SiO2 gate dielectric can be replaced by crystalline RE-oxides in the next batch fabrication.

- Next-generation surveys like the Legacy Survey of Space and Time (LSST) on the Vera C. Rubin Observatory (Rubin) will generate orders of magnitude more discoveries of transients and variable stars than previous surveys. To prepare for this data deluge, we developed the Photometric LSST Astronomical Time-series Classification Challenge (PLAsTiCC), a competition that aimed to catalyze the development of robust classifiers under LSST-like conditions of a nonrepresentative training set for a large photometric test set of imbalanced classes. Over 1000 teams participated in PLAsTiCC, which was hosted in the Kaggle data science competition platform between 2018 September 28 and 2018 December 17, ultimately identifying three winners in 2019 February. Participants produced classifiers employing a diverse set of machine-learning techniques including hybrid combinations and ensemble averages of a range of approaches, among them boosted decision trees, neural networks, and multilayer perceptrons. The strong performance of the top three classifiers on Type Ia supernovae and kilonovae represent a major improvement over the current state of the art within astronomy. This paper summarizes the most promising methods and evaluates their results in detail, highlighting future directions both for classifier development and simulation needs for a next-generation PLAsTiCC data set.

- <b><i>Background/Aims:</i></b> National Plans for Rare Diseases (RDs) are the common denominator of current public health policy concerns on RDs across the EU. With the aim of a better distribution of the available resources, they conjugate the European objective that aims at ensuring that patients with RDs have access to high-quality care - including diagnostics, treatment and rehabilitation - with the national priorities of selecting specific measures for adoption and implementation. <b><i>Methods:</i></b> The European Project for Rare Diseases National Plans Development (EUROPLAN, www.europlanproject.eu) is cofunded by the EU Commission (DG-SANCO) and is coordinated by the Italian National Center for Rare Diseases of the Istituto Superiore di Sanità (ISS). The EUROPLAN goal is to promote the implementation of National Plans or Strategies to tackle RDs and share relevant experiences within countries, linking national efforts, through a common strategy at a European level. In order to fulfill these objectives, EUROPLAN involved health authorities, clinicians, scientists, the European Organisation for Rare Diseases (EURORDIS), and many other patient groups as associated and collaborating partners from several European countries. <b><i>Results:</i></b> The project was launched in 2008 and foresaw 2 implementation phases: phase 1 (2008-2011) to build the consensus definition of operational tools (recommendations and indicators), and the ongoing phase 2 (2012-2015), mainly aimed at capacity building with the proactive involvement of multilevel stakeholders. EUROPLAN is facilitating and accelerating the implementation of National Plans in almost all EU and several non-EU Countries. <b><i>Conclusions:</i></b> EUROPLAN is a European and an international process more than a project, and it could be defined as a ‘litmus test' demonstrating how the collaboration between institutions and patients' associations can accelerate the process of awareness and development of policies and actions.
