How to interpret the relationship between the low-level features, such as some statistical characteristics of color and texture, and the high-level aesthetic properties, such as warm or cold, soft or hard, has been a hot research topic of neuroaesthetics. Contrary to the black-box method widely used in the fields of machine learning and pattern recognition, we build a white-box model with the hierarchical feed-forward structure inspired by neurobiological mechanisms underlying the aesthetic perception of visual art. In the experiment, the aesthetic judgments for 8 pairs of aesthetic antonyms are carried out for a set of 151 visual textures. For each visual texture, 106 low-level features are extracted. Then, ten more useful and effective features are selected through neighborhood component analysis to reduce information redundancy and control the complexity of the model. Finally, model building of the beauty appreciation of visual textures using multiple linear or nonlinear regression methods is detailed. Compared with our previous work, a more robust feature selection algorithm, neighborhood component analysis, is used to reduce information redundancy and control computation complexity of the model. Some nonlinear models are also adopted and achieved higher prediction accuracy when compared with the previous linear models. Additionally, the selection strategy of aesthetic antonyms and the selection standards of the core set of them are also explained. This research also suggests that the aesthetic perception and appreciation of visual textures can be predictable based on the computed low-level features.

The Aesthetic

Several models of visual aesthetic perception have been proposed in recent years. Such models have drawn on investigations into the neural underpinnings of visual aesthetics, utilizing neurophysiological techniques and brain imaging techniques including functional magnetic resonance imaging, magnetoencephalography, and electroencephalography. The neural mechanisms underlying the aesthetic perception of the visual arts have been explained from the perspectives of neuropsychology, brain and cognitive science, informatics, and statistics. Although corresponding models have been constructed, the majority of these models contain elements that are difficult to be simulated or quantified using simple mathematical functions. In this review, we discuss the hypotheses, conceptions, and structures of six typical models for human aesthetic appreciation in the visual domain: the neuropsychological, information processing, mirror, quartet, and two hierarchical feed-forward layered models. Additionally, the neural foundation of aesthetic perception, appreciation, or judgement for each model is summarized. The development of a unified framework for the neurobiological mechanisms underlying the aesthetic perception of visual art and the validation of this framework via mathematical simulation is an interesting challenge in neuroaesthetics research. This review aims to provide information regarding the most promising proposals for bridging the gap between visual information processing and brain activity involved in aesthetic appreciation.

The origins of “micropollutants” are discussed and classified. It is suggested that assessing the risk and ensuring an acceptably low level of adverse effects from these substances requires information or control of three factors (exposure, toxicity and characteristics of the victim or organism) which combine to generate the toxic event. Methods of estimating exposure are discussed, especially environmental models. Ultimately, it should be possible to couple these models to toxicity data in a rational, rigorous manner to elucidate the extent of risk and control it to acceptable levels.

Pattern Occurrences

In multivariate time series, outlying data may be often observed that do not fit the common pattern. Occurrences of outliers are unpredictable events that may severely distort the analysis of the multivariate time series. For instance, model building, seasonality assessment, and forecasting may be seriously affected by undetected outliers. The structure dependence of the multivariate time series gives rise to the well-known smearing and masking phenomena that prevent using most outliers' identification techniques. It may be noticed, however, that a convenient way for representing multiple outliers consists of superimposing a deterministic disturbance to a gaussian multivariate time series. Then outliers may be modeled as nongaussian time series components. Independent component analysis is a recently developed tool that is likely to be able to extract possible outlier patterns. In practice, independent component analysis may be used to analyze multivariate observable time series and separate regular and outlying unobservable components. In the factor models framework too, it is shown that independent component analysis is a useful tool for detection of outliers in multivariate time series. Some algorithms that perform independent component analysis are compared. It has been found that all algorithms are effective in detecting various types of outliers, such as patches, level shifts, and isolated outliers, even at the beginning or the end of the stretch of observations. Also, there is no appreciable difference in the ability of different algorithms to display the outlying observations pattern.

In this article the authors described the experience of lipofilling usage at the National Cancer Institute. Aim of this work was to improve the aesthetic results of surgical treatment of breast cancer patients by the usage of lipofilling in patients after breast reconstruction. The description of methods of lipofilling and their application in cancer patients, the benefits of usage of LipiVage® system was performed. Materials and methods. The study included 42 women with breast cancer, who received special treatment in 2012–2016. The main group included 21 patients that have received special treatment and undergone lipofilling. The control group included 21 patients, who received only special treatment, (with no lipofilling). Different objective and subjective criteria for evaluating the effectiveness of lipofilling in achieving a satisfactory aesthetic result in patients, who underwent radical and reconstructive surgery for breast cancer, were used in this investigation. The results shows that the implementation of lipofilling improves the aesthetic perception after breast reconstruction in 20 % of patients, decreases the number of complications after reconstructive operations and are not accompanied by a worsening of results of special treatment in breast cancer patients. In conclusion it can be noted that our results show a high efficiency of lipofilling after special treatment, its safety and advisability for further usage.

This article examines the art and travels of two contemporary Chinese artists – Ai Weiwei and Cai Guo-Qiang – to explore how each of them successfully navigates the rapidly shifting terrains and interests of the Chinese state and the global high art industry while simultaneously articulating a distinct politics and practice of creative ambivalence. We argue that these two artists’ creative productions and strategies: (1) refute various western critics’ critique of Chinese artists as inauthentic imitators of western art who produce exotic representations of China and Chinese identity for western consumption; (2) call into question the Chinese government’s numerous efforts to simultaneously promote and control Chinese contemporary art for nationalist/statist purposes. Furthermore, we unpack how both artists deploy various resources to produce complex works that interrogate and demonstrate the clashes of power, culture and identity in global spaces of encounter.

Plissit Model

Recent years with the widespread use of social media, the aesthetic perception of societies has started to change. People, with the desire to be liked, turn to plastic surgery with the importance they attach to physical appearance. Women's aesthetic genital surgery operations also show a parallel trend with this trend. Aesthetic surgery operations performed in the genital area are mostly designed and focused on sexual satisfaction and attractiveness. Among these procedures that do not have a medical indication, the most common ones are; labiaplasty, perineoplasty, vaginoplasty, hymenectomy and G-point amplification. Although the operations are performed by gynecology and plastic and reconstructive surgery specialists, pre-and postoperative care is provided to the patient by midwives and nurses. In this context, in this review, it is aimed to evaluate the counseling and care role of midwives and nurses with the Ex-PLISSIT Model, as well as the recommendations of international obstetrics and gynecology associations for genital aesthetic surgery operations and these operations.

This study assesses changing aesthetic values and their characteristics in urban environments based on human perception. With this in mind, a model for assessing the aesthetic values of the urban environment based on the three steps of human cognition has been developed to elaborate the user's perception in different urban environments. The results of the survey confirm that by changing urban morphology the aesthetic perception of the environment also changes. The finding of this research opens up a new window for urban planners to assess the aesthetic effects of the elements of urban spatial configuration for future urban development.

Purpose This study aims to evaluate the effect of the installed photovoltaic (PV) systems on the aesthetic perception of the mosque’s architectural form. It also aims to develop a framework for integrating PV cells with the various elements of the building type. Design/methodology/approach The study adopted a mixed-method approach comprising both qualitative and quantitative techniques for data collection procedures. This includes surveys, literature review, focus groups and an experiment. Findings The results revealed a negative impact of the building-applied PV panels on people’s perception of the mosque’s architectural form. However, integrating the PV cells with the mosque form was perceived as more aesthetically pleasing. Certain integrating PV strategies integrated more harmoniously with certain mosque styles. Research limitations/implications This study is focused on limited styles of one building type. Extra research is needed to explore the differences between the different participated groups. Originality/value There is a lack of research that explores the ways the installed PV systems impact the users’ architectural aesthetic perception of the mosque. This study informs the design process and practice and construction industry by highlighting the opportunities PV systems, as a legitimate sustainable energy resource, offers to architects and manufacturers.

Recent research has suggested that low-level psychoacoustic parameters such as loudness and spectral brightness are correlated with musical chills, a subjective emotional experience accompanied by goosebumps, shivers, and tingling sensations. These relationships may be explained by a vigilance theory of chills, through the process of auditory looming; however, these correlations or theories have never been causally tested. In the current study, participants ( N = 40) listened to five variations (original, low loudness, high loudness, low brightness, high brightness) of an experimental and control piece of chills music, characterized by a crescendo and guitar solo respectively; this qualitative distinction was made based on whether the underlying musical structure of the pieces was or was not capable of engaging auditory looming processes. It was predicted that increases in loudness would result in increased chills frequency across participants, indicated by button presses; brightness was included as an exploratory parameter. Results show that for the experimental piece, increases in loudness resulted in significantly more frequent chills experiences, and increases in brightness significantly reduced the frequency of chills, whereas no effects were found for the control piece. Findings are discussed in terms of vigilance and social bonding theories of chills, and the complex interactions between low-level psychoacoustic properties and higher-level musical structures.
