TL;DR: The Symposium "Challenges of fingerprinting in indoor positioning and navigation" as discussed by the authors was held at Barcelona (Spain) on May 3rd and 4th, 2016, with an audience comprised academic, scientists, engineers, company representatives, and institutional members.
Abstract: The symposium “Challenges of Fingerprinting in Indoor Positioning and Navigation” took place at Barcelona (Spain) on May 3rd and 4th, 2016. The audience comprised academic, scientists, engineers, company representatives, and institutional members. The program offered reports on the state of the art for indoor positioning based on fingerprinting, as well as discussions of challenges of the technology for the near future. Discussions gave potential users of indoor positioning technology the opportunity to expose real indoor location problems that need to be solved. This chapter gives a summary of the topics dealt in the symposium and constitutes a brief introduction to the chapters that appear in the entire book.

TL;DR: This pioneering study analyses and provides evidence of potentially misleading internet‐based disclosure strategies and proposes a set of measures for corporate information presentation.
Abstract: – The aim of this paper is to contribute to the understanding of how the internet interacts with businesses and markets. The authors aims to focus on the internet press releases of annual results to illustrate how corporate communication is used and managed strategically online., – The authors describe the increasing importance of the internet for communicating firms' performance to investors, financial media and the stock market, then identify and discuss a number of techniques that might be used to potentially manipulate the online presentation of financial results. Thus the authors conducted a content analysis of the internet press releases in two consecutive years (2008 and 2009) by a wide range of companies listed in the IBEX 35 share index., – This paper provides in‐depth insights into content analysis techniques by providing examples of how potentially misleading disclosure practices are included in press releases. Moreover the paper investigates the use of seven potentially misleading disclosure practices appearing in press releases that optimise the way in which company results are presented., – Regulators may consider the normalisation of the content of internet press releases to avoid or reduce opportunistic disclosure practices. Moreover, investors should be aware of the use of these practices to reduce the misleading effect when processing corporate information., – This pioneering study analyses and provides evidence of potentially misleading internet‐based disclosure strategies. Furthermore the paper proposes a set of measures for corporate information presentation.

TL;DR: The results demonstrate the feasibility of using TMS to causally modulate antisaccade-associated computations in the non-human primate brain and support the use of this approach in monkeys to study brain function and its non-invasive neuromodulation for exploratory and therapeutic purposes.
Abstract: A combination of oculometric measurements, invasive electrophysiological recordings and microstimulation have proven instrumental to study the role of the Frontal Eye Field (FEF) in saccadic activity. We hereby gauged the ability of a non-invasive neurostimulation technology, Transcranial Magnetic Stimulation (TMS), to causally interfere with frontal activity in two macaque rhesus monkeys trained to perform a saccadic antisaccade task. We show that online single pulse TMS significantly modulated antisaccade latencies. Such effects proved dependent on TMS site (effects on FEF but not on an actively stimulated control site), TMS modality (present under active but not sham TMS on the FEF area), TMS intensity (intensities of at least 40% of the TMS machine maximal output required), TMS timing (more robust for pulses delivered at 150 ms than at 100 post target onset) and visual hemifield (relative latency decreases mainly for ipsilateral AS). Our results demonstrate the feasibility of using TMS to causally modulate antisaccade-associated computations in the non-human primate brain and support the use of this approach in monkeys to study brain function and its non-invasive neuromodulation for exploratory and therapeutic purposes.

27 Apr 2009TL;DR: This paper evaluates in this paper two DNS privacy-preserving approaches recently presented in the literature and discusses some benefits and limitations of these proposals, and points out the necessity of additional measures to enhance their security.
Abstract: The rise of new Internet services, especially those related to the integration of people and physical objects to the net, makes visible the limitations of the DNS protocol. The exchange of data through DNS procedures flows today into hostile networks as clear text. Packets within this exchange can easily be captured by intermediary nodes in the resolution path and eventually disclosed. Privacy issues may thus arise if sensitive data is captured and sold with malicious purposes. We evaluate in this paper two DNS privacy-preserving approaches recently presented in the literature. We discuss some benefits and limitations of these proposals, and we point out the necessity of additional measures to enhance their security.
