An Adaptive Robust Predictive Current Control for Three-Phase Grid-Connected Inverters

2011

This paper presents an adaptive robust predictive current control (RPCC) for grid-connected three-phase inverters that exhibit zero steady-state current error. The error correction is achieved by means of an adaptive strategy that works in parallel with the deadbeat algorithm, therefore preserving the typical fast response of the predictive law. The resulting control adapts to any particular L or LCL filter by estimation of the resistive part of the filter. As a variety of the RPCC class of control, it offers the best tradeoff between robustness and speed. © 2009 IEEE.

A Nullclines Approach to the Study of 2D Artificial Network

2019


 
 The system of two the first order ordinary differential equations arising in the gene regulatory networks theory is studied. The structure of attractors for this system is described for three important behavioral cases: activation, inhibition, mixed activation-inhibition. The geometrical approach combined with the vector field analysis allows treating the problem in full generality. A number of propositions are stated and the proof is geometrical, avoiding complex analytic. Although not all the possible cases are considered, the instructions are given what to do in any particular situation.

Hydrophilic and Hydrophobic Polymeric Derivatives of Anti-Inflammatory Agents Such as Alclofenac, Ketoprofen, and Ibuprofen

1991

Macromolecular prodrugs of a hydrophilic polymer [α,β-poly( N- hydroxyethyl)-DL-aspartamide (PHEA)] was used as a drug carrier. Three poly- (HEA)-NSAID adducts were studied: poly(HEA)-Alclofenac, poly(HEA)-Keto profen, and poly(HEA)-Ibuprofen. Prodrugs with different drug content were synthesized both as water-soluble and water-insoluble agents. Hydrolysis of water-soluble adducts in a simulated gastric juice was studied.

Combining multi-typologies landslide susceptibility maps: a case study for the Visso area (central Italy)

2023

The research proposes a simple but geomorphologically adequate method to produce a combined landslide susceptibility map. In fact, in a logic of real use, offering type-specific landslide susceptibility maps to land use planners and administration could be not a successful solution. On the other hand, the simple grouping of more types of landslides could be misleading for model calibration considering that the relationships between slope failures and geo-environmental predictors should be conveyed by the abundance of each type of landslide resulting not specific and diagnostic for each typology. In this test, after having produced independent models for flow, slide and complex landslide by …

Uso y funciones de los «hashtags» evidenciales en Twitter

2021

This paper examines evidential hashtags on Twitter. The analyzed hashtags contain constructions of the verb decir (‘to say’) that are preceded by the hash symbol (e.g., #dicen, #sedice, #esodicen, #dicenporahí), which have not been analyzed from the perspective of evidentiality. An exploratory and qualitative study was performed using a sample of 94 tweets that were published over six months. The analysis addresses structural and semantic-pragmatic parameters. According to the results of the analysis, evidential hashtags can transmit reportative, quotative and folklore evidentiality. Furthermore, the evidential meaning of the hashtags is accompanied by pragmatic functions such as attenuatio…

Prognostic Factors in Childhood Anaplastic Large Cell Lymphoma: Long Term Results of the International ALCL99 Trial

2020

With the aim of describing the long-term follow-up and to define the prognostic role of the clinical/pathological/molecular characteristics at diagnosis for childhood, adolescent and young adults affected by anaplastic large cell lymphoma (ALCL), we analyzed 420 patients aged up to 22 years homogeneously treated within the international ALCL99 trial. The 10-year progression free survival (PFS) was 70% and overall survival was 90%, rare late relapses occurred but no secondary malignancies were reported. Among clinical/pathological characteristics, only patients presenting a small cell/lymphohistiocytic (SC/LH) pattern were independently associated with risk of failure (hazard ratio = 2.49). …

IC3D Classification of Corneal Dystrophies—Edition 2

2015

To update the 2008 International Classification of Corneal Dystrophies (IC3D) incorporating new clinical, histopathologic, and genetic information.The IC3D reviewed worldwide peer-reviewed articles for new information on corneal dystrophies published between 2008 and 2014. Using this information, corneal dystrophy templates and anatomic classification were updated. New clinical, histopathologic, and confocal photographs were added.On the basis of revisiting the cellular origin of corneal dystrophy, a modified anatomic classification is proposed consisting of (1) epithelial and subepithelial dystrophies, (2) epithelial-stromal TGFBI dystrophies, (3) stromal dystrophies, and (4) endothelial d…

Effects of clozapine metabolites and chronic clozapine treatment on rat brain GABAA receptors

1996

Abstract Similarly to clozapine, a clozapine metabolite, N -desmethylclozapine, but not clozapine N -oxide, antagonized brain γ-aminobutyric acid type A (GABA A ) receptors at high micromolar concentrations. However, daily subcutaneous injections of clozapine (10 and 25 mg/kg) and haloperidol (0.5 mg/kg) for 14 days failed to alter the modulation by GABA of rat cerebrocortical and cerebellar benzodiazepine ([ 3 H]flunitrazepam) or convulsant ( t -[ 35 S]bicyclophosphorothionate) binding sites of the GABA A receptor. The results thus suggest that the GABA A receptor antagonism exerted by chronic in vivo clozapine treatment is weak as compared to this treatment's actions on certain monoamine …
