Applying Erez and ten Brink's dirty paper codes to data-hiding
No full textStructured codes are known to be necessary in practical implementations of capacity-approaching "dirty paper schemes". In this paper we study the performance of a recently proposed dirty paper technique, by Erez and ten Brink which, to the authors' knowledge, is firstly applied to data-hiding, and compare it with other existing approaches. Specifically, we compare it with conventional side-informed schemes previously used in data-hiding based on repetition and turbo coding. We show that a significant improvement can be achieved using Erez and ten Brink's proposal. We also study the considerations we have to take into account when these codes are used in data-hiding, mainly related with perceptual questions.</p
The role of seawater endocytosis in the biomineralization process in calcareous foraminifera
No full textForaminifera are unicellular organisms that inhabit the oceans in various ecosystems. The majority of the foraminifera precipitate calcitic shells and are among the major CaCO3 producers in the oceans. They comprise an important component of the global carbon cycle and also provide valuable paleoceanographic information based on the relative abundance of stable isotopes and trace elements (proxies) in their shells. Understanding the biomineralization processes in foraminifera is important for predicting their calcification response to ocean acidification and for reliable interpretation of the paleoceanographic proxies. Most models of biomineralization invoke the involvement of membrane ion transporters (channels and pumps) in the delivery of Ca2+ and other ions to the calcification site. Here we show, in contrast, that in the benthic foraminiferan Amphistegina lobifera, (a shallow water species), transport of seawater via fluid phase endocytosis may account for most of the ions supplied to the calcification site. During their intracellular passage the seawater vacuoles undergo alkalization that elevates the CO32? concentration and further enhances their calcifying potential. This mechanism of biomineralization may explain why many calcareous foraminifera can be good recorders of paleoceanographic conditions. It may also explain the sensitivity to ocean acidification that was observed in several planktonic and benthic species. <br/

A little elastic for a better performance: kinesiotaping of the motor effector modulates neural mechanisms for rhythmic movements
No full textA rhythmic motor performance is brought about by an integration of timing information with movements. Investigations on the millisecond time scale distinguish two forms of time control, event-based timing and emergent timing. While event-based timing asserts the existence of a central internal timekeeper for the control of repetitive movements, the emergent timing perspective claims that timing emerges from dynamic control of nontemporal movements parameters. We have recently demonstrated that the precision of an isochronous performance, defined as performance of repeated movements having a uniform duration, was insensible to auditory stimuli of various characteristics (Bravi et al., 2014). Such finding has led us to investigate whether the application of an elastic therapeutic tape (Kinesio® Tex taping; KTT) used for treating athletic injuries and a variety of physical disorders, is able to reduce the timing variability of repetitive rhythmic movement. Young healthy subjects, tested with and without KTT, have participated in sessions in which sets of repeated isochronous wrist's flexion-extensions (IWFEs) were performed under various auditory conditions and during their recall. Kinematics was recorded and temporal parameters were extracted and analyzed. Our results show that the application of KTT decreases the variability of rhythmic movements by a twofold effect: on the one hand KTT provides extra proprioceptive information activating cutaneous mechanoreceptors, on the other KTT biases toward the emergent timing thus modulating the processes for rhythmic movements. Therefore, KTT appears able to render movements less audio dependent by relieving, at least partially, the central structures from time control and making available more resources for an augmented performance

Planktic foraminifera shell chemistry response to seawater chemistry: Pliocene-Pleistocene seawater Mg/Ca, temperature and sea level change
No full textForaminifera Mg/Ca paleothermometry forms the basis of a substantial portion of ocean temperature reconstruction over the last 5 Ma. Furthermore, coupled Mg/Ca–oxygen isotope (δ18O) measurements of benthic foraminifera can constrain eustatic sea level (ESL) independent of paleo-shoreline derived approaches. However, this technique suffers from uncertainty regarding the secular variation of the Mg/Ca seawater ratio (Mg/Casw) on timescales of millions of years. Here we present coupled seawater–test Mg/Ca–temperature laboratory calibrations of Globigerinoides ruber in order to test the widely held
assumptions that (1) seawater–test Mg/Ca co-vary linearly, and (2) the Mg/Ca–temperature sensitivity remains constant with changing Mg/Casw. We find a nonlinear Mg/Catest–Mg/Casw relationship and a lowering of the Mg/Ca–temperature sensitivity at lower than modern Mg/Casw from 9.0% ◦C−1 at Mg/Casw = 5.2 mol mol−1 to 7.5 ± 0.9%◦C−1 at 3.4 mol mol−1. Using our calibrations to more accurately calculate the offset between Mg/Ca and biomarker-derived paleotemperatures for four sites, we derive a Pliocene
Mg/Casw ratio of ∼4.3 mol mol−1. This Mg/Casw implies Pliocene ocean temperature 0.9–1.9 ◦C higher than previously reported and, by extension, ESL ∼30 m lower compared to when one assumes that Pliocene Mg/Casw is the same as at present. Correcting existing benthic foraminifera datasets for Mg/Casw indicates that deep water source composition must have changed through time, therefore seawater oxygen isotope reconstructions relative to present day cannot be used to directly reconstruct Pliocene ESL

Paced auditory stimuli with distinct characteristics affect differently the clock-like neural process?
No full textIn millisecond timing research, two forms of timing are distinguished: event-based and emergent timing (Spencer and Ivry, Brain Cogn, 2005, 58, 84-93). The essential difference between the two timing modes is considered to be consisting in the involvement or noninvolment of a clock-like neural process, i.e., an abstract effector-independent representation of the time intervals to be produced (Wing and Kristofferson, Percept Psycholphys, 1973, 14: 5-12). The character of movements in a rhythmic motor task is considered a key factor for eliciting a specific mode of timing. The class of discrete movements, defined as having a clear-cut beginning and end, shown to engage the involvement of clock-like neural process (Huys et al., 2008, PLoS Comput Biol, 4: e1000061.10.1371). Discrete movements are not the only ones favoring exploitation of the event-based timing. Recent studies have demonstrated that salient auditory markers, such as streams of clicks (Torre and Delignières, 2008, Biol Cyb, 99: 159-170) and tactile feedback (Studenka et al., 2012, Q J Exp Psychol 65, 1086-1100.10.1080), are also able to elicit the event-based timing. Here, we investigated whether simple and complex paced auditory stimuli, as streams of clicks and excerpts of music, influence differently the processes for temporal regulation. Particularly, we wanted to study if music, when compared with clicks, has a different power in encouraging the event-based timing. Also, since Zelaznik and Rosembaum (2010, J Exp Psychol H Percept Perfor, 36: 1565-1575) provided evidence that external auditory event representation of movement favors event-based timing, we decided to explore whether the recall of an auditory stimulus, where auditory imagery is involved and is simulating an internal auditory representation, might influence timing control processes. In order to answer to these questions, subjects have participated in a session in which sets of repeated isochronous wrist's flexion-extensions were performed under various auditory conditions and during their recall. Kinematics was recorded and temporal parameters were extracted and analyzed. Results indicate that streams of clicks and music do affect differently the timing processes, with music having only a minor role in provoking event-based timing, especially evident at high ranges of tempi. In addition, the auditory experience, constructed of components drawn from memory in the absence of direct sensory instigation of experience, favors the involvement of event-based timing
CHR for Social Responsibility
No full textPublicly traded corporations often operate against the public's interest, serving a very limited group of stakeholders. This is counter-intuitive, since the public as a whole owns these corporations through direct investment in the stock-market, as well as indirect investment in mutual, index, and pension funds. Interestingly, the public's role in the proxy voting process, which
allows shareholders to influence their company's direction and decisions, is essentially ignored by individual investors. We
speculate that a prime reason for this lack of participation is information overload, and the disproportionate efforts required for an investor to make an informed decision. In this paper we propose a CHR based model that significantly simplifies the decision making process, allowing users to set general guidelines that can be applied to every company they own to produce voting recommendations. The use of CHR here is particularly advantageous as it allows users to easily track back the most relevant data that was used to formulate the decision, without the user having to go through large amounts of irrelevant information. Finally we describe a simplified algorithm that could be used as part of this model
