ChromaGAN: Adversarial Picture Colorization with Semantic Class Distribution

The colorization of grayscale images is an ill-posed problem, with multiple correct solutions. In this paper, we propose an adversarial learning colorization approach coupled with semantic information. A generative network is used to infer the chromaticity of a given grayscale image conditioned to semantic clues. This network is framed in an adversarial model that learns to colorize by incorporating perceptual and semantic understanding of color and class distributions. The model is trained via a fully self-supervised strategy. Qualitative and quantitative results show the capacity of the proposed method to colorize images in a realistic way achieving state-of-the-art results.Comment: 8 pages + reference

La Agresión como variable predictora de la Respuesta Matutina de Cortisol en adultos jóvenes.

Few studies have examined therelationship between the cortisol awakening response (CAR) and aggression inhealthy youth adults. This study analyzes this relationship in 83 women (38 inluteal phase and 45 in follicular phase of menstrual cycle) and 20 men.Salivary-free cortisol measures of the CAR were obtained immediately followingawakening and 30, 45, and 60 minutes afterwards. Additionally, participantscompleted a self-report of aggression. Men presented lower levels of CAR thanwomen in luteal phase. Men were also liable to present more physical aggressionthan women, independently of their menstrual phase. General aggression andspecifically verbal aggression are predictors of CAR in men. In women, verbalaggression predicts CAR during the follicular phase of the menstrual cycle;whereas anger and physical aggression do so during the luteal phase. CAR may beused as a valid marker of proneness to aggression – but must be considered differentlydepending on gender and menstrual cycle of women. This study offers relevantinformation on the hormonal bases of aggression and so contributes to theliterature on alleviating problems related to violence.Escasas investigaciones han examinado la relaciónentre la respuesta matutina de Cortisol (CAR) y la agresión en adultos jóvenessanos. Este estudio analiza dicha relación en 83 mujeres (38 en fase lútea y 45en fase folicular del ciclo menstrual) y 20 hombres. Se obtuvieron muestras desaliva inmediatamente después del despertar y 30, 45 y 60 minutos después.Además, los participantes cumplimentaron un autoinforme de agresión. Loshombres presentan niveles más bajos de CAR que las mujeres en fase lútea y unamayor agresión física que las mujeres, independientemente de la fase del cicloen la que se encuentren. La agresión en general y la verbal en particular predicenla CAR en hombres. En mujeres, la agresión verbal modula la CAR durante la fasefolicular, mientras que la ira y la agresión física durante la lútea. La CARpuede utilizarse como un marcador fiable de predisposición hacia la agresión, yha de considerarse de forma diversa en función del género y de la fase delciclo menstrual. Esta investigación aporta información significativa sobre las baseshormonales de la agresión, por lo que contribuye a la búsqueda de soluciones para aliviar problemasrelacionados con la violencia

La neurocriminología como disciplina aplicada emergente

Neurocriminology aims to apply neuroscience methodology and study  techniques  in  order to understand, predict, study and even predict delinquencyandcriminality.Neurocriminological knowledge could be used in violence prevention, diagnostic and treatment, and also in estimating the likelihood of recidivism. All this is not free of ethical and  legal  issues,  but  neuroscience is becoming an important influence when understanding and studying violent and criminal behaviour. Moreover, Positive Neurocriminology focus on the positive processes such as empathy, altruism, positive emotions and prosocial behaviour, among others. This knowledge could be used in the development of prevention and intervention delinquency programs.La neurocriminología persigue aplicar la metodología y las técnicas de estudio de las neurociencias para comprender, predecir, tratar e incluso prevenir la violencia y la criminalidad. Los conocimientos neurocriminológicos podrían ser empleados tanto en la prevención como en el diagnóstico y el tratamiento de la violencia, así como en la estimación de la probabilidad de reincidencia. Aunque todo ello no está libre de cuestiones ético-legales, la neurociencia se está convirtiendo en una importante influencia en la comprensión y el estudio del comportamiento violento y criminal. En este contexto, la neurocriminología positiva se centra en los procesos positivos como la empatía, el altruismo, las emociones positivas y la conducta prosocial, entre otros. Estos conocimientos podrían ser utilizados en la elaboración de programas de prevención e intervención de la delincuencia

Palynological characterization of species of Verbenaceae J. St.-Hil. and Lamiaceae Martinov (Lamiales Bromhead)

Clerodendrum splendens A. Chev., Clerodendrum x speciosum Tiej. & Binn, Clerodendrum thomsonae Balf. F., Clerodendrum ugandense L., Congea tomentosa Roxb., Duranta erecta L., Petrea volubilis L. and Petrea volubilis f. albiflora (Standl.) Standl. pollen grains were acetolyzed, photographed and measured under light microscopy and scanning electron microscopy. Values presented are averages in micrometers. Grains are monads, radially symmetrical, isopolar, large (C. ugandense, very large, C. tomentosa, small-medium and D. erecta, medium),tricolpate (P. volubilis f. albiflora, dimorphic grains with 3-4 colpus). Ambitus is circular (C. tomentosa and D. erecta, sub-circular, P. volubilis , triangular, P. volubilis f. albiflora, triangular-quadrangular). The form is oblate-spheroidal (C. splendens, C. x speciosum, C. ugandense), prolate-spheroidal (C. thomsonae), prolate (C. tomentosa), suboblate (D. erecta) and oblate (P. volubilis, P. volubilis f. albiflora). Exine thickness is in C. splendens 4,28, C. x speciosum 4,19, C. ugandense 4,33, C. thomsonae 4,18, C. tomentosa 1,4, D. erecta 1,55, P. volubilis 2,49, P. volubilis f. albiflora 2,68. Ornamentation is micro-echinate (C. splendens, C. x speciosum, C. thomsonae), echinate (C. ugandense), reticulate (C. tomentosa), psilate (D. erecta, P. volubilis, P. volubulis f. albiflora). Duranta and Petrea are close to Verbenaceae pattern, Congea to Lamiaceae and Clerodendrum loosely to Lamiaceae
