Nanostructured sensors have unique capabilities that can be tailored to advantage in advancing the diagnosis, monitoring and cure of several diseases and health conditions. This report aims at providing a current perspective on, (a) the emerging clinical needs that defines the challenges to be addressed by nanostructured sensors, with specific emphasis on early stage diagnosis, drug-diagnostic combinations, and predictive models to design therapy, (b) the emerging industry trends in in vitro diagnostics, mobile health care, high-throughput molecular and cell-based diagnostic platforms, and (c) recent instances of nanostructured biosensors, including promising sensing concepts that can be enhanced using nanostructures that carry high promise towards catering to the emerging clinical needs, as well as the market/industry trends. © 2014 Elsevier Ltd.

This paper is a sequel to and builds upon the survey paper on optimal power flow (OPF) [4]. It provides an up-to-date critical review of the recent major advancements in the OPF state-of-the-art since 2010, identifies further challenging developments needed in order to adapt to the transition toward smarter grids, and indicates ways to address these challenges. The paper focuses on three main topics which are reviewed in chronological order of appearance: deterministic OPF, risk-based OPF, and OPF under uncertainty. A special attention is paid to the algorithms for the core optimizers intervening in the master and slave nonlinear programming problems resulting from OPF decomposition. © 2016 Elsevier B.V.

A cross-check of botanical names databases revealed the presence of 19 cases of homonymy which are hereby resolved by proposing replacement names. Most cases concern diatom genera (Bacillariophyta) names which are preoccupied by spermatophytes. While Loranthella nom. nov. (Spermatophyta, Loranthaceae) and Ochradiscus nom. nov. (Spermatophyta, Resedaceae) are proposed as new names for spermatophytes, new diatom names are proposed for genera that are currently placed in the families Amphipleuraceae, Coscinodiscaceae, Hemiaulaceae, Hemidiscaceae, Melosiraceae, Metascolioneidaceae nom. nov., Naviculaceae, Pyxillaceae, Stictodiscaceae and Surirellaceae. With one exception (i.e. Eileencoxia nom. nov.) all remaining diatom genera that are discussed in the present paper are marine and/or fossil elements. The particularities of each case are briefly discussed. A total of one hundred and three new combinations are proposed. © 2016 Magnolia Press.

In the framework of approaches which question the narrow scope of the deterministic N-1 security criterion, this work proposes an enhanced risk-based AC security-constrained optimal power flow (RB-SCOPF) problem formulation to aid transmission system operators (TSOs) trading-off economy and (thermal) security. The system security is controlled through an overall system risk constraint, which accumulates the individual risk related to each contingency, defined as the product between the probability of contingency occurrence and the contingency severity. The latter is expressed in terms of the amount of voluntary load shedding which, complementary to conventional corrective actions, is able to correct violation of post-contingency long-term thermal limits. The existing RB-SCOPF formulations are enhanced with short-term thermal post-contingency limits, aimed at avoiding cascade line tripping, and TSO operating rule. The main features of the RB-SCOPF formulation are illustrated in the IEEE 118-bus system. © 2015 Elsevier B.V. All rights reserved.

The present invention relates to a compact and portable mass spectrometer device comprising a source of ions, a non-scanning magnetic sector for separating ions originating at the source of ions according to their mass-to-charge ratios, and a detection means. The magnetic sector comprises an ion entrance plane and at least two ion exit planes, which allow to optimize the resolving power of the mass spectrometer for specific mass-to charge ratio sub-ranges.
