Emergency Evacuation Behavior in Small Island Developing States: Hurricane Irma in Sint Maarten

Medina Pena, N.J. (author), Sanchez, Arlex (author), Vojinovic, Zoran (author)

Disasters triggered by natural hazards are becoming more frequent and more intense, causing damage to infrastructure and causing loss of life. One way to reduce disaster risk is by evacuating the hazardous area. However, despite the amount of literature that exists on evacuation behavior, there is still a lack of agreement on which variables...

Emergent coexistence in multispecies microbial communities

Chang, Chang Yu (author), Bajic, D. (author), Vila, Jean C.C. (author), Estrela, Sylvie (author), Sanchez, Alvaro (author)

Understanding the mechanisms that maintain microbial biodiversity is a critical aspiration in ecology. Past work on microbial coexistence has largely focused on species pairs, but it is unclear whether pairwise coexistence in isolation is required for coexistence in a multispecies community. To address this question, we conducted hundreds of...

Titanium Trisulfide Nanosheets and Nanoribbons for Field Emission-Based Nanodevices

Pawbake, Amit S. (author), Khare, Ruchita T. (author), Island, Joshua O. (author), Flores, Eduardo (author), Ares, Jose R. (author), Sanchez, Carlos (author), Ferrer, Isabel J. (author), van der Zant, H.S.J. (author), Castellanos Gomez, A. (author)

The field emission (FE) properties of TiS3 nanosheets and nanoribbons, synthesized by direct sulfuration of bulk titanium, are investigated. The nanosheets show an enhanced FE behavior with a low turn-on field of ∼0.3 V/μm, required for drawing an emission current density of ∼10 μA/cm2. Interestingly, the TiS3 nanosheet emitter delivered a...

Trajectory optimization of a planetary sunshade around L1

Heiligers, M.J. (author), Oggionni, F. (author), Sanchez, Joan-Pau (author)

A planetary sunshade is a large, reflecting disk built to shield the Earth from a small fraction of solar irradiance and partly compensate global warming caused by greenhouse gas emissions. As a specific form of solar geoengineering, the sunshade is an emergency solution that would be implemented to prevent catastrophic climate change, while...

Eder, Matthias (author), Sanchez, Isabelle (author), Camarasa, Carole (author), Daran, J.G. (author), Legras, Jean Luc (author), Dequin, Sylvie (author)

Dimethyl sulfide (DMS) is a sulfur containing volatile that enhances general fruity aroma and imparts aromatic notes in wine. The most important precursor of DMS is S-methylmethionine (SMM), which is synthesized by grapes and can be metabolized by the yeast S. cerevisiae during wine fermentation. Precursor molecules left after fermentation...

The computational burden and the time required to train a deep reinforcement learning (DRL) can be appreciable, especially for the particular case of a DRL control used for frequency control of multi-electrical energy storage (MEESS). This paper presents an assessment of four training configurations of the actor and critic network to determine...

Motivation: Protein function prediction is a difficult bioinformatics problem. Many recent methods use deep neural networks to learn complex sequence representations and predict function from these. Deep supervised models require a lot of labeled training data which are not available for this task. However, a very large amount of protein...

Assessing socioeconomic vulnerability after a hurricane: A combined use of an index-based approach and principal components analysis

Medina Pena, N.J. (author), Abebe, Y.A. (author), Sanchez, Arlex (author), Vojinovic, Zoran (author)

Small Island Developing States (SIDS) are vulnerable to sea-level rise and hydro-meteorological hazards. In addition to the efforts to reduce the hazards, a holistic strategy that also addresses the vulnerability and exposure of residents and their assets is essential to mitigate the impacts of such hazards. Evaluating the socioeconomic...

Descriptive Statistical Analysis of Frequency control-related variables of Nordic Power System

Acosta, Martha N. (author), Andrade, Manuel A. (author), Sanchez, Francisco (author), Gonzalez-Longatt, Francisco (author), Rueda, José L. (author)

This paper presents a descriptive statistical analysis (DSA) of time-series of electro-mechanical quantities related to the frequency control (e.g. kinetic energy (KE), electrical frequency and power demand) of the Nordic power system (NPS). The idea of the DSA is to identify main observables features and patterns between these variables....

Exploring trade-offs among the multiple benefits of green-blue-grey infrastructure for urban flood mitigation

Alves, Alida (author), Vojinovic, Zoran (author), Kapelan, Z. (author), Sanchez, Arlex (author), Gersonius, Berry (author)

Climate change is presenting one of the main challenges to our planet. In parallel, all regions of the world are projected to urbanise further. Consequently, sustainable development challenges will be increasingly concentrated in cities. A resulting impact is the increment of expected urban flood risk in many areas around the globe....

Flood risk management in Sint Maarten–A coupled agent-based and flood modelling method

Abebe, Y.A. (author), Ghorbani, Amineh (author), Nikolic, I. (author), Sanchez, Arlex (author), Vojinovic, Zoran (author)

Disaster risk reduction is a major concern of small island developing states. Measures to reduce risk should not only be based on the magnitude of physical hazard, but also on the exposure and vulnerability of communities. In this article, we examine flood risk management policies in the Caribbean island of Sint Maarten using coupled agent-based...

Security Assessment of System Frequency Response

Sanchez, F. (author), Gonzalez-Longatt, Francisco (author), Rueda, José L. (author)

Low inertia power systems experience more extreme frequency dynamics immediately after a disturbance. A higher rate of change of frequency (ROCOF) contributes to a lower frequency nadir which could trigger load shedding schemes. Active power injections in a time frame of two seconds or less are necessary to maintain frequency stability. This...

Assessing the Co-Benefits of green-blue-grey infrastructure for sustainable urban flood risk management

Alves, Alida (author), Gersonius, Berry (author), Kapelan, Z. (author), Vojinovic, Zoran (author), Sanchez, Arlex (author)

Green-blue infrastructures in urban spaces offer several co-benefits besides flood risk reduction, such as water savings, energy savings due to less cooling usage, air quality improvement and carbon sequestration. Traditionally, these co-benefits were not included in decision making processes for flood risk management. In this work we present...

Crystal orientation and grain size: Do they determine optoelectronic properties of MAPbI₃ Perovskite?

Muscarella, Loreta A. (author), Hutter, E.M. (author), Sanchez, Sandy (author), Dieleman, Christian D. (author), Savenije, T.J. (author), Hagfeldt, Anders (author), Saliba, Michael (author), Ehrler, Bruno (author)

Growing large, oriented grains of perovskite often leads to efficient devices, but it is unclear if properties of the grains are responsible for the efficiency. Domains observed in SEM are commonly misidentified with crystallographic grains, but SEM images do not provide diffraction information. We study methylammoinium lead iodide (MAPbI<sub...
