The CRONE Toolbox (https://powered-paraglider.com/activation-key/?patch=3627), developed since the nineties by the CRONE team, is a Matlab Toolbox dedicated to fractional calculus. It is currently evolving towards an object oriented version, which allows many enhancements. Three main user classes, dedicated to fractional systems representations namely fractional transfer functions (frac_tf), fractional zeros poles and gain (frac_zpk), and fractional state-space (frac_ss), are developed. All three user classes are children of a parent class (frac_lti) which contains some common attributes of fractional systems.

The neural mechanisms that underlie the registration of decision costs have never been directly investigated. We hypothesized that costs might be evaluated based on the degree of engagement of brain regions subserving executive control; these specifically include lateral prefrontal cortex (LPFC) and dorsomedial frontal cortex (DMFC) (16–19). Our hypothesis finds support in existing evidence that decision makers prefer to minimize demands for working memory (20), task set configuration (21), and conflict resolution (22–24), all hallmark functions of the executive control system.
We have examined the idea that decision-makers experience a motive to minimize internal decision costs. Although the impact of internal costs on choice behavior (2, 3) and cognition in general (4, 21, 31) has been widely considered, little is known about how such costs are registered or evaluated at the neural level. Our results identify a relationship between decision costs and activity in left LPFC. We found that activity in this region correlated with participants’ self-reported avoidance tendency across epochs of a decision-making task (Experiment 1), and with directly observed rates of avoidance across individuals (Experiment 2).
Each block began with a 60 s induction period of passive looking at the hand or object. Then 30 laser pulses were applied to the dorsum of the right hand. To avoid nociceptor sensitization, the laser was moved randomly between pulses. At least 7 s elapsed between pulses. Participants rated pain intensity and unpleasantness after each pulse, using a 101-point VAS in which 0 corresponded to no pain and 100 to the worst pain imaginable.
Participants responded to the prompt by pressing one of four keys. It was explained that participants’ indicated preferences would not influence future trials and that they should use the full range of the scale, for instance, responding “a lot” for blocks they preferred to avoid relative to others in the experiment.
Our finding counters the intuitive possibility that decision costs reflect overall mental workload or metabolic consumption throughout the brain (33–37). Our task engaged a constellation of brain regions consistent with past studies of task switching (25), and it would have been logically possible for internal costs to depend on activity fluctuations throughout this network. In fact, however, we observed the effect uniquely in LPFC, implying a specific role for this region and for the control processes it is believed to implement.
The moti- vation for developing the CRONE toolbox was first to fill a gap, since no software support was dedicated to fractional calculus and its applications in signal processing and.

Our second experiment sought to confirm the relevance of LPFC to the evaluation of decision costs, with costs now measured directly in terms of observed avoidance behavior. Here we assumed that decision costs would vary not just over time but also across individuals.
Nowadays, landslide has been one of the most frequent and seriously widespread natural hazards all over the world. Most of the projects developed for Matlab run on Octave too. Simulink is a graphical environment for simulation and Model-Based Design of multidomain dynamic and embedded systems. Matlab is presented along with a tutorial and a case study to simplify the usage among the engineer community. More specifically in the framework given by Quantitative Feedback Theory (QFT), traditionally the search of an optimum design, a non convex and nonlinear optimization problem, is simplified by linearizing and/or convexifying the problem.

Time-delay systems are frequently used to present the design of proportional integral derivative (PID) controllers and particularly of fractional-order PID controllers. Feliu-Batlle et al. proposed the design of robust fractional-order PID controllers for two irrigation canals. The first system models a 10 km-long section of the 60 km-long Güira de Melena Main Irrigation Canal (GMMIC) in Habana County, Cuba. The controller has to control the downstream end water level of one section by using its upstream gate position.

Experiment 1 elicited repeated self-reports of experienced decision costs. Costs were measured in terms of participants’ rated desire to avoid the task. Participants completed 10-trial blocks of simple decisions in a task-switching paradigm (judging the magnitude or parity of single digits). Participants were told that the specific stimulus sequence in any block would be generated by one of four different undisclosed algorithms (“sources”). Participants were asked to rate, after every block, their inclination to avoid future blocks from the same source. We assumed that there would be endogenous variability both in brain activity and in reported avoidance tendencies, even though stimuli were in fact generated using a uniform procedure. We further assumed ratings would reflect the same internal factors that drove avoidance in our behavioral experiment. Whole-brain analyses evaluated within-subject correlations between block-related BOLD amplitudes and the subsequently assigned avoidance ratings. We expected to observe a positive correlation in control-related cortical regions.
BOLD response amplitudes for individual error-free blocks were estimated in a GLM. The model also contained regressors for error trials, blocks containing errors, rating-selection events, and linear effects of individual-trial RT.
The latest version of The WFDB Toolbox for MATLAB is currently unknown. These are used to define a template for the desired open-loop frequency response, that ensures the robustness of the controller within its uncertainty domain. I. Alpha and beta event-related desynchronization. I am hopeful that Microsoft doesn't mess up Minecraft too much but already a system that ran Minecraft just fine in Windows 7, could not run the base Minecraft in Windows 10 except their Windows 10 beta, which is based on the Mobile version. If your webcam has stopped working after installing recently-released Microsoft's big Anniversary Update for Windows 10, you are not alone.
Both the present results showing analgesic effects of seeing the body and previous findings showing tactile enhancement (Kennett et al, 2001) could therefore be explained by visual modulation of somatosensory GABAergic interneurons. This speculation is supported by multisensory influences on cortical inhibition in other physiological systems. For example, viewing a hand extends the TMS-evoked silent period compared with viewing a fixation cross (Schütz-Bosbach et al, 2009). Furthermore, Dehner et al. (2004) described a GABA-dependent auditory-somatosensory inhibitory effect in cats.
Each subject's data yielded a contrast map representing high-demand vs. low-demand task performance. This map was spatially normalized, and differences between the two groups were assessed in individual voxels using a nonparametric rank sum test.

During scanning, trials were shown at 2-s intervals, grouped into 96 10-trial blocks. The same digit never appeared twice consecutively. The first color was chosen randomly; thereafter, colors switched five, six, seven, or eight times per block.
Only positive effects are depicted in A and B. (C) In left and right lateral prefrontal cortex clusters, avoidance ratings were correlated with single-block BOLD amplitude estimates. Correlations in C were estimated after factoring out the effects of RT and error shown in A and B. (D) Avoidance rating-correlated regions found in a follow-up analysis that did not exclude the influence of error and RT.
Instructions were designed to elicit an event-by-event measure of participants’ inclination to avoid the cognitive task. For this reason, instructions intentionally refrained from describing block-to-block differences in any detail.

Choice cues appeared as circular patterned patches. Participants mouse-clicked a patch to reveal a colored number. Depending on the number's color, participants judged either its magnitude or parity, responding via left-hand keypress. There was a 250-ms intertrial interval; otherwise the task was self-paced. One choice cue repeated the previously shown color on 90% of trials (low-demand), whereas the other switched colors on 90% of trials (high-demand). Each subject completed eight 75-trial runs. Choice cues in each run were unique in appearance and location.

This interpretation parallels conclusions from work on a seemingly very different topic: the perception of physical heaviness. In principle, the heaviness of an object held in the hand could be judged either on the basis of “bottom-up” sensory signals reflecting the object's downward force or “top-down” efferent signals engaged in supporting the object. Research has suggested that the latter play a predominant role (40). Analogously, decision costs might arise not only from bottom-up performance feedback, but also from top-down control engagement. Humans may experience a drive to be “frugal” in their exertion of cognitive control, alongside their motive to perform tasks quickly and successfully.
However, modulation from seeing one's body could involve either enhancement or inhibition. If enhancing effects observed previously for touch apply across somatic modalities, increases in perceived pain and laser-evoked potentials (LEPs) might be expected. However, many intermodal interactions involving pain are inhibitory. Touch reduces both pain levels (Wall and Sweet, 1967; Higgens et al, 1971) and cortical pain processing (Lundeberg, 1985; Inui et al, 2006). Chronic pain is associated with reduced tactile sensitivity on the affected region (Moriwaki and Yuge, 1999) and reduced size of the corresponding primary somatosensory cortex (SI) tactile representation (Maihöfner et al, 2003; Pleger et al, 2006). Conversely, tactile discrimination training reduces chronic central pain (Flor et al, 2001; Moseley et al, 2008b), an effect enhanced by seeing the body (Moseley and Wiech, 2009). In each case, touch and pain appear antagonistic, suggesting that vision of the body might have different effects on touch and pain. Furthermore, seeing someone else's hand in pain reduces early cortical pain processing (Valeriani et al, 2008). However, the effects of seeing one's own body on nociception are unknown.
No attempt was made to disguise the presence of the experimenter or to make their hand physically resemble the participant's hand. There was a single block of each condition, the order of which was counterbalanced across participants.

Subjects performed the DST in a behavioral testing room after scanning was complete. Participants were instructed that, unlike during the scanning phase, they were free to choose one alternative more often if they developed a preference. Each participant's low-demand selection rates in eight 60-trial runs were evaluated in a signed-rank test against 0/50 to provide the basis for between-subjects fMRI analyses.
Participants were members of the Princeton University community. In the preliminary behavioral experiment, n = 12 (age 18–22, 7 females). In fMRI Experiment 1, n = 10 (age 18–34, 4 females), with one additional participant excluded because of high error (19/5%). In fMRI Experiment 2, n = 22 (age 18–30, 14 females); one additional participant misunderstood instructions during scanning and was excluded.
