Auditory cortical event-related potentials to pitch deviances in rats
1998
Abstract We recorded epidural event-related potentials (ERPs) from the auditory cortex in anesthetized rats when pitch-deviant tones were presented in a homogenous series of standard tones (oddball condition). Additionally, deviant tones were presented without standard tones (deviant-alone condition). ERPs to deviant tones in the oddball condition differed significantly from ERPs to standard tones at the latency range of 63–243 ms. On the other hand, ERPs to deviant tones in the deviant-alone condition did not differ from ERPs to standard tones until 196 ms from stimulus onset. The results suggest that oddball stimuli can be neurophysiologically discriminated in anesthetized rats. Furthermo…
Semantic Verbal Fluency in Children with and without Autism Spectrum Disorder: Relationship with Chronological Age and IQ
2016
We administered a semantic verbal fluency (SVF) task to two groups of children (age range from 5 to 8): 47 diagnosed with Autism Spectrum Disorder (ASD Group) and 53 with typical development (Comparison Group), matched on gender, chronological age, and non-verbal IQ. Four specific indexes were calculated from the SVF task, reflecting the different underlying cognitive strategies used: clustering (component of generativity and lexical-semantic access), and switching (executive component, cognitive flexibility). First, we compared the performance of the two groups on the different SVF task indicators, with the ASD group scoring lower than the Comparison Group, although the difference was grea…
Correction of Long Vehicle Off Tracking by Multiple Axle Steering
2019
When planning the road vehicles for the transport of passengers or goods, engineers should take care to contrast some undesirable phenomena in the lateral dynamics, such as high-speed instability or off tracking. While the former is less troubling in the slow heavy vehicles, the latter is a serious problem due to the risk of invading the neighbouring lanes. The use of multi-wheel steering may completely cancel this drawback and, pursuing an optimized correlation among the steering angles, a functional inter-dependence based on the cubic “witch of Agnesi” is found to be very promising. Simple control systems with electromechanical or electronic components may be easily implemented for the mu…
The neolithic settlement of Limoneros (Elche, Alicante)
2020
[EN] This paper shows the results of rescue archaeology campaigns undertaken on the site of Limoneros, an open-air settlement located to the south of Elche (Alicante), in the alluvial plain of the Vinalopó river and dated on the first half of the 5th millennium cal BC. The settlement entails different negative structures, including two stretches of ditch, silos and basins, structures finally reused as a waste area. The analysis of the recovered evidences allows the characterization of the activities developed by a farming community in a territory articulated by the river Vinalopó, where other settlements dated back to the same period have been documented. Therefore, Limoneros supplies relev…
Balance as Symbol and Object of Art
2014
The symbolic use of the balance is reviewed, covering mythology and religion, icons and arts, its use in astronomy and astrology as well as in literature and music. In Old Egypt many paintings show men’s height balances symbolically used for soul weighing. In Greece the fate balance was known. In the Roman Empire the symbolic use changed to justice fairness, and legitimacy of coins and this holds until modern time. In the Bible and the Koran fair weighing in trade are demanded. In the Book of Revelation the balance is symbol for misery. Michael archangel became guide of the deceased to the last judgement and weighed the poor sinner against his good deeds. In the witch balance the mass of th…
Highly Efficient Capacitive Galvanic Isolation for EV Charging Stations
2022
This paper proposes an isolated Switched Capacitor (SC) power converter which provides galvanic isolation through Capacitive Power Transfer (CPT). The combination of these two technologies might answer for electrical and power requirements in different electrical mobility application fields, such as battery charging. Accordingly, due to the low conversion losses the combination of these two technologies can provide, compact, cost effective and highly efficient power converters can be derived, thus potentially answering the scalability requirements for the Electric Vehicles (EV) market. To assess the operation of the proposed circuital solution, a Full Bridge (FB) CPT isolated interfacing co…
Highly Compact Partial Power Converter for a Highly Efficient PV-BESS Stacked Generation System
2022
The inherently intermittent nature of photovoltaic (PV) energy has brought increasing interest towards the integration between PV sources and Battery Energy Storage Systems (BESS). In this paper, a Series Partial Power Processing (PPP) converter based on Capacitive Power Transfer (CPT) is proposed to integrate PV and BESS in a grid-connected inverter system. The proposed converter has been simulated according to a PV string capable to provide 1430 W under full irradiance conditions, a BESS nominal voltage equal to 215 V and a solar inverter assumed to operate with a minimum voltage of 150 V and a maximum current of 10 A. Simulation tests carried out at different conditions of solar radiatio…

Essential versus accessory aspects of cell death: recommendations of the NCCD 2015
2015
Cells exposed to extreme physicochemical or mechanical stimuli die in an uncontrollable manner, as a result of their immediate structural breakdown. Such an unavoidable variant of cellular demise is generally referred to as ?accidental cell death' (ACD). In most settings, however, cell death is initiated by a genetically encoded apparatus, correlating with the fact that its course can be altered by pharmacologic or genetic interventions. "Regulated cell death" (RCD) can occur as part of physiologic programs or can be activated once adaptive responses to perturbations of the extracellular or intracellular microenvironment fail. The biochemical phenomena that accompany RCD may be harnessed to…
A photoswitchable helical peptide with light-controllable interface/transmembrane topology in lipidic membranes
2021
Summary The spontaneous insertion of helical transmembrane (TM) polypeptides into lipid bilayers is driven by three sequential equilibria: solution-to-membrane interface (MI) partition, unstructured-to-helical folding, and MI-to-TM helix insertion. A bottleneck for understanding these three steps is the lack of experimental approaches to perturb membrane-bound hydrophobic polypeptides out of equilibrium rapidly and reversibly. Here, we report on a 24-residues-long hydrophobic α-helical polypeptide, covalently coupled to an azobenzene photoswitch (KCALP-azo), which displays a light-controllable TM/MI equilibrium in hydrated lipid bilayers. FTIR spectroscopy reveals that trans KCALP-azo folds…
