Astrophysical bound on the majoron-Higgs-boson coupling
1989
Abstract We show that the coupling of the “standard” Higgs boson to majorons, that could lead to a very fast decay of the neutral Higgs scalar to invisible modes, can be bounded using astrophysical arguments. We discuss the relevance of this bound for low-energy phenomenology related to majoron production. The bound so obtained may also jeopardize the stability of the VEV hierarchy in the doublet and triplet majoron models if the mass of the top quark is less than the W mass. A similar analysis may be applied to other models which exhibit Goldstone-or pseudo-Goldstone-bosons in the spectrum.
Vertical redistribution of moisture and aerosol in orographic mixed-phase clouds
2020
Orographic wave clouds offer a natural laboratory to investigate cloud microphysical processes and their representation in atmospheric models. Wave clouds impact the larger-scale flow by the vertical redistribution of moisture and aerosol. Here we use detailed cloud microphysical observations from the Ice in Clouds Experiment – Layer Clouds (ICE-L) campaign to evaluate the recently developed Cloud Aerosol Interacting Microphysics (CASIM) module in the Met Office Unified Model (UM) with a particular focus on different parameterizations for heterogeneous freezing. Modelled and observed thermodynamic and microphysical properties agree very well (deviation of air temperature <1 K; spe…
Sting Jets in Simulations of a Real Cyclone by Two Mesoscale Models
2010
AbstractThe existence of sting jets as a potential source of damaging surface winds during the passage of extratropical cyclones has recently been recognized. However, there are still very few published studies on the subject. Furthermore, although it is known that other models are capable of reproducing sting jets, in the published literature only one numerical model [the Met Office Unified Model (MetUM)] has been used to numerically analyze these phenomena. This article aims to improve our understanding of the processes that contribute to the development of sting jets and show that model differences affect the evolution of modeled sting jets. A sting jet event during the passage of a cycl…
La riunificazione familiare dello straniero nei trattati sui diritti umani
2010
Family reunification contributes to the integration of aliens in the countries of destination and the development of their personality as well, but it entails the increase in the demand for social facilities. As a consequence States tend to reduce the opportunities for family reunification. The study analyses the activity of the organs of control set up by the international conventions on human rights and aims at identifying the obligations on States’ sovereignty stemming from the rules of these conventions protecting family life or disciplining family reunification. In assessing the lawfulness of States’ rules on family reunification or decisions on individual cases these organs verify whe…

ɛ-type contribution to baryon asymmetry from colored Higgs triplets
1991
In scenarios where the cosmological baryon asymmetry is generated in the decay of heavy colored Higgs triplets at the one-loop level (at least two triplets are needed), it is shown that in addition to the conventional triangle loop ({epsilon}{prime}-type effect), a new kind of diagram must be considered. This new type of diagram has its origin in the mixing of the two Higgs fields ({epsilon}-type effect). The mixing of the two Higgs fields violates {ital CP} provided they have at least two common decay channels. For small mixing angles, the new contribution can be bigger than the conventional one.
Multi Architecture Optimization of a Hybrid Electric Vehicle Using Object-Oriented Programming
2017
This article presents an energetic macroscopic representation multi-architecture model for hybrid vehicles using object-oriented programming. This approach is successfully used to evaluate the power performance and fuel consumption of different vehicles on different driving cycles. An optimization of power source sizing (ICE, EM and Battery) and system control, based on simulation results, is carried. Different architectures are compared for given cycles and optimization of hybrid architecture will also be possible.
Burnout Syndrome in municipal health managers
2016
Resumo Introdução Os gestores municipais da saúde devem responder às demandas de suas equipes e dos pacientes do Sistema Único de Saúde, enfrentando cotidianamente situações potencialmente estressoras. A sobrecarga no trabalho pode levar à exaustão física e mental, com esgotamento dos recursos emocionais, e desencadear a Síndrome de Burnout (SB), cujas consequências podem atingir o serviço gerenciado, uma vez que, ao desempenhar essa atividade laboral, tomam-se decisões determinantes nas ações em saúde que afetam muitas pessoas. Este estudo verificou a presença da SB nos gestores municipais de saúde do Estado de São Paulo. Métodos Estudo do tipo transversal no qual foram coletados dados soc…
Information Systems Students’ Impressions on Learning Modeling Enterprise Architectures
2020
This Full Research Paper presents enterprise architecture (EA) modeling tools utilized in an educational context. EA is a well-known and a commonly used approach for organizational development aiming to improve the alignment of business operations and information technology. This high level design of information technology (IT) driven business operations lays the foundations on lower level technical activities such as the design and implementation of application programs and features, system boundary interfaces, database distribution and data pipes, and system recovery. Organizations’ architectures are made visible by creating EA artefacts, such as business process diagrams, data models and…
