"Hoc opus fodit Pirus Martini de Pisis". Note su un capolavoro di oreficeria toscana con smalti del XIV secolo a Geraci Siculo
2012
Il prezioso ostensorio, trasformato in reliquiario nel XVII secolo, conservato nel tesoro della Chiesa Madre di Geraci Siculo (PA), è già noto da tempo agli studiosi perché firmato dall'orafo pisano Piro di Martino (lettura dell'iscrizione corretta, piuttosto che "Pino di Sammartino"). Il saggio, che per la prima volta ne descrive gli smalti traslucidi, propone una datazione alla seconda metà del XIV secolo per ragioni stilistiche e ne attribuisce la committenza al conte Francesco II Ventimiglia. The precious monstrance, transformed into a reliquary in the 17th century, kept in the treasury of the Mother Church of Geraci Siculo (PA), has long been known to scholars because it was signed by …
Splines in convex sets under constraints of two‐sided inequality type in a hyperplane
2008
The problem of minimization of a smoothing functional under inequality constraints is considered in a hyperplane. The conditions of the existence of a solution are obtained and some properties of this solution are investigated. It is proved that the solution is a spline. The method for its construction is suggested. First Published Online: 14 Oct 2010
Towards Seamless IoT Device-Edge-Cloud Continuum:
2021
In this paper we revisit a taxonomy of client-side IoT software architectures that we presented a few years ago. We note that the emergence of inexpensive AI/ML hardware and new communication technologies are broadening the architectural options for IoT devices even further. These options can have a significant impact on the overall end-to-end architecture and topology of IoT systems, e.g., in determining how much computation can be performed on the edge of the network. We study the implications of the IoT device architecture choices in light of the new observations, as well as make some new predictions about future directions. Additionally, we make a case for isomorphic IoT systems in whic…
Bodily obsessions : intrusiveness of organs in somatic obsessive–compulsive disorder
2022
AbstractIn this paper, I will provide a phenomenological analysis of somatic obsessions at times present in obsessive–compulsive disorder. I will compare two different types of bodily obsessions, which have a different neurological-physiological underpinning: anguishing awareness of one’s own heartbeat and of one’s own breathing. In addition, I will contrast these two with how one experiences one’s own liver. I will use the concepts "tactility obsessions” and "motility obsessions”, which I have coined for the purpose of this comparison. In other words, these are obsessions concerning the felt sense of one’s autonomous organs and obsessions concerning one’s ability to voluntarily move. Ultim…
The induced smoothed LASSO
2016
We propose a new lasso-type estimator of regression coefficients for regression models. Our proposal relies on the recent idea of induced smoothing and leads to estimators with sampling distribution somewhat close to the Normal one, regardless of their true value, along with the corresponding reliable covariance matrix. As a consequence inference (e.g. p-values) may be carried out relatively easily. We present results from some simulation experiments.
Cardiac cycle and respiration phase affect responses to the conditioned stimulus in young adults trained in trace eyeblink conditioning
2022
Rhythms of breathing and heartbeat are linked to each other as well as to rhythms of the brain. Our recent studies suggest that presenting the conditioned stimulus during expiration or during the diastolic phase of the cardiac cycle facilitates neural processing of that stimulus and improves learning an eyeblink classical conditioning task. To date, it has not been examined whether utilizing information from both respiration and cardiac cycle phases simultaneously allows even more efficient modulation of learning. Here we studied whether the timing of the conditioned stimulus to different cardiorespiratory rhythm phase combinations affects learning trace eyeblink conditioning in healthy you…
CA3–CA1 long‐term potentiation occurs regardless of respiration and cardiac cycle phases in urethane‐anesthetized rats
2023
Breathing and heartbeat synchronize to each other and to brain function and affect cognition in humans. However, it is not clear how cardiorespiratory rhythms modulate such basic processes as synaptic plasticity thought to underlie learning. Thus, we studied if respiration and cardiac cycle phases at burst stimulation onset affect hippocampal long-term potentiation (LTP) in the CA3–CA1 synapse in urethane-anesthetized adult male Sprague–Dawley rats. In a between-subjects design, we timed burst stimulation of the ventral hippocampal commissure (vHC) to systole or diastole either during expiration or inspiration and recorded responses throughout the hippocampus with a linear probe. As classic…
Using altered states of consciousness in improvisational music therapy : the potential of resonance frequency breathing
2018
Improvisational music therapy is a type of creative arts therapy in which clients are encouraged to express themselves through the symbolic and non-verbal medium of music, by creating free music improvisations together with the therapist. The present research aims at investigating whether the efficacy of this method can be further enhanced by purposefully accessing the ego-quieting properties of altered states of consciousness. This work proceeds in three main steps. First, the notions of consciousness and its alteration are examined and reformulated, resulting in a more comprehensive theoretical model. Then, existing methods for inducing altered states of consciousness are evaluated in ter…
A Place for Life
2010
The belief in the existence of extraterrestrial civilizations starts from the so-called principle of mediocrity. This principle postulates that Earth is a normal planet that rotates around a normal star, which in turn is located in a normal galaxy. That is to say, there is nothing so special in our world as to make it unique. This is a logical conclusion, toward which we are guided by the successive “Copernican turns” that science has suffered throughout its long history, and which has removed us from the central position we once believed to occupy in the universe.
Comparing the cost-efficiency of CoAP and HTTP in Web of Things applications
2014
Abstract Constrained Application Protocol (CoAP) has been introduced as a simpler alternative to the Hypertext Transfer Protocol (HTTP) for connecting constrained smart objects to the Web. The adoption of the protocol depends on its relative advantage, and the cost–benefit associated with the use of the protocol is a significant factor affecting a protocol adoption decision. This paper aims at deepening the understanding of the cost–benefits of CoAP and identifies the application scenarios where its use is likely to be economically justifiable. The paper analyzes the costs of using CoAP and HTTP in the Web of Things (WoT) applications, by identifying the components of the total cost of owne…
