The DeToxSTM aims to develop imaging processing tools able to denoise scanning tunneling microscopy(STM) images. The STM has been considered the most important technique to image,control and monitorize molecular systems with atomic resolution under a wide range of experimentalconditions that enable molecule visualization. Usually, it is a hard task to find the bestconditions to obtain high resolution images with low noise. An adequate STM image interpretationcan be affected by noise signals and therefore it is necessary to correct and eliminate them. Thetechnique needs a long-term temporal analysis (i.e. many hours) and the drift can be severe enoughto displace the scan window beyond the original regions of interest.This project intends to develop new algorithms to denoise the images acquired with STM. Theinnovation goal is to formulate the sparse denoise problem as a morphological component analysisproblem, where the components are related to the periodicity of use of the elements present in thelearned dictionary (periodic v.s. aperiodic). This can be solved recurring to recently proposed workon efficient computation of convolutional sparse representations.

A investigação incide sobre um tema emergente na sociologia nacional e internacional: as experiências e os direitos de cidadania das pessoas transexuais e transgénero. Concretamente, explora o impacto das novas abordagens médico-legais da “identidade de género” nas experiências identitárias, estéticas corporais e aceitação social, familiar e íntima destas pessoas. A nível nacional, a “lei de identidade de género” (Lei 7/2011) representa o reconhecimento civil da transição de género e a desvinculação entre sexo e género, ou entre identidades de género e corpos sexuados, ao validar a existência de corpos de fêmea com identidades masculinas e vice-versa. A questão central é perceber o impacto desta recente possibilidade na vida dos indivíduos trans e, simultaneamente, o seu contributo para a mudança social. Metodologicamente, recorrer-se-á a análise legislativa comparada, entrevistas em profundidade a indivíduos de diversas expressões de (trans)género, bem como a profissionais de saúde implicados nos cuidados trans-específicos e representantes de associações LGBT.

One major goal in this project is to develop an analytical formulation,as well as a stochastic Monte-Carlo (MC) simulator, that allow us to study in a rigorous way the impact of in-band crosstalk, both incoherent and coherent, originated in CDC ROADMs in the performance of flexible grid networks, considering 16-QAM and 64-QAM 400 Gbps signals.On a network-side perspective, the emergence of modulation formats with higher-order constellations and, consequently, with stricter performance margins has increased the importance of physical impairment awareness in the network planning process. Thus, it is essential to incorporate the effects of in-band crosstalk, along with other effects, in an impairment-aware routing and spectrum assignment (RSA) framework. This framework should be able to efficiently provision paths and spectrum for superchannels based on M-QAM carriers in a CDC-ROADM network, while using the physical model as a performance validation tool for candidate optical paths
