Weakly coupled map lattice models for multicellular patterning and collective normalization of abnormal single-cell states

2017

We present a weakly coupled map lattice model for patterning that explores the effects exerted by weakening the local dynamic rules on model biological and artificial networks composed of two-state building blocks (cells). To this end, we use two cellular automata models based on: (i) a smooth majority rule (model I) and (ii) a set of rules similar to those of Conway's Game of Life (model II). The normal and abnormal cell states evolve according with local rules that are modulated by a parameter $\kappa$. This parameter quantifies the effective weakening of the prescribed rules due to the limited coupling of each cell to its neighborhood and can be experimentally controlled by appropriate e…

Indirect majority and minority influence: An exploratory study

1991

In a 2 × 2 design, 85 subjects were asked to estimate the size of angles (direct influence) that were either 90 or 85°, after being confronted with incorrect judgements of a majority (88 per cent) or a minority (12 per cent) of people estimating the angles at 50°. Additionally, pre- and post-test measures were used to establish indirect influence on subjects' judgements pertaining to acute angles (i.e. on the estimation of the length of lines constituting the angles, and on the imaginary weight of figures represented by these angles). Overall, little direct influence is observed. This may partly be due to the introduction of a denial of the credibility of the source in all conditions. In fa…

Determinación de la edad de un extranjero indocumentado : A propósito de la sentencia de la audiencia provincial de barcelona, de 24 de enero de 2020

2021

In recent years, immigration of minors has increased, which means that administrations establish a differentiated treatment for this sector of immigration due to the fact that they are minors; There are many aspects to take into account in these cases, including verifying the minority age, a fact that is more complicated when it comes to adolescents. This is what is analyzed by the Judgment of the Provincial Court of Barcelona, of January 24, 2020, which confirms the Resolution of the General Directorate of Attention to Children and Adolescents, which agreed to the closure of the homelessness file and the admission of the plaintiff in a Protection Center until the verification of their pers…

Estimation of the age of majority through radiographic evaluation of the third molar maturation degree

2020

Background Although the third molar is the tooth with the greatest anatomical and developmental variability, some authors consider it important to estimate whether a subject is of legal age or not. The Demirjian’s technique is the most widely used tool to estimate dental age and was therefore used in our study to assess possible correlation between the age of majority and the maturational degree of the lower third molars, evaluated through radiographic images. Material and Methods This observational transversal study was conducted on 180 panoramic radiographs from consecutive patients. The degree of maturation of the lower third molar was independently classified by two observers, according…

LA CONTRATTAZIONE COLLETTIVA NEGLI STATI UNITI DAL WAGNER ACT AI NOSTRI GIORNI

2016

LA CONTRATTAZIONE COLLETTIVA NEGLI STATI UNITI. DAL WAGNER ACT AI NOSTRI GIORNI. — Riassunto. Il presente lavoro analizza la legislazione statunitense in materia di contrattazione collettiva sin dall’emanazione del Wagner Act nel 1935. Al riguardo, vengono discusse le regole per il riconoscimento dei sindacati nei luoghi di lavoro e per la stipula degli accordi collettivi (principio di maggioranza e rappresentanza esclusiva, obbligo di negoziare secondo buona fede) e per la gestione del conflitto industriale (arbitrato e clausola di tregua): sulla scorta di un approccio storico-critico e dei leading case giurisprudenzialil’articolosottolineailcarattereprettamenteaziendaleeprivatisticodellere…

Quantum Algorithms for Learning Symmetric Juntas via Adversary Bound

2014

In this paper, we study the following variant of the junta learning problem. We are given oracle access to a Boolean function f on n variables that only depends on k variables, and, when restricted to them, equals some predefined function h. The task is to identify the variables the function depends on. This is a generalisation of the Bernstein-Vazirani problem (when h is the XOR function) and the combinatorial group testing problem (when h is the OR function). We analyse the general case using the adversary bound, and give an alternative formulation for the quantum query complexity of this problem. We construct optimal quantum query algorithms for the cases when h is the OR function (compl…

Same work, lower grade? Student ethnicity and teachers’ subjective assessments

2010

Previous research shows that ethnic minority students perform poorer in school when they are taught by ethnic majority teachers. Why this is the case was unclear. This paper focuses on one important potential explanation: I examine whether ethnic majority teachers grade minority and majority students differently for the same work. Using an experiment, I rule out the existence of such a direct grading bias. I do find indirect evidence for alternative explanations: teachers report lower expectations and unfavorable attitudes that both likely affect their behavior towards minority students, potentially inducing them to perform below their ability level. Effects of having majority teachers on m…

Detection of Ventricular Fibrillation Using the Image from Time-Frequency Representation and Combined Classifiers without Feature Extraction

2018

Due the fact that the required therapy to treat Ventricular Fibrillation (V F) is aggressive (electric shock), the lack of a proper detection and recovering therapy could cause serious injuries to the patient or trigger a ventricular fibrillation, or even death. This work describes the development of an automatic diagnostic system for the detection of the occurrence of V F in real time by means of the time-frequency representation (T F R) image of the ECG. The main novelties are the use of the T F R image as input for a classification process, as well as the use of combined classifiers. The feature extraction stage is eliminated and, together with the use of specialized binary classifiers, …

Ensemble of Hankel Matrices for Face Emotion Recognition

2015

In this paper, a face emotion is considered as the result of the composition of multiple concurrent signals, each corresponding to the movements of a specific facial muscle. These concurrent signals are represented by means of a set of multi-scale appearance features that might be correlated with one or more concurrent signals. The extraction of these appearance features from a sequence of face images yields to a set of time series. This paper proposes to use the dynamics regulating each appearance feature time series to recognize among different face emotions. To this purpose, an ensemble of Hankel matrices corresponding to the extracted time series is used for emotion classification withi…
