"Shaking His Hairy Chaps": The Iconography of Bearded Snakes

<p>The bearded snake is an unusual motif that appears in a variety of contexts and media throughout the Classical world. It is used in Greek, Etruscan, Roman, and Egyptian art and literature. This thesis addresses the Greek use of the bearded snake. The beard of the snake, much like the beard of a human figure, varies in terms of its size, shape, and level of detailing. It may be a simple single line or a series of long, clearly defined hairs. The use of this human feature on serpents has received minimal attention. When the motif is discussed it is generally only considered in terms of its use in one context, such as on depictions of Zeus Meilichios or on the Lakonian hero reliefs. The aim of this thesis is to discuss the use of the bearded snake in the most common contexts in which it may occur in order to provide a better understanding of the meaning of this unusual motif. Such contexts include anguiform deities, pure serpents, hybrid creatures, and attributes of monsters and deities. Two of the more influential explanations of the use of the beard are those by Aelian, from the third century AD, and Jane Harrison, from 1903. These interpretations consider the bearded snake in slightly different terms. Where Aelian believes the beard to indicate a male serpent, Harrison considers the feature to be a means through which the snake is implied to be an anthropomorphic deity. Chapter One provides the background interpretations of the snake and the beard as distinct motifs. The findings from this chapter will form the basis for the interpretations given in Chapters Two and Three. Chapter Two considers the flaws of Aelian’s explanation of the beard as an indicator of gender, by looking at the use of the beard in the context of divine and monstrous women such as Medusa and Athena. Chapter Three addresses Harrison’s anthropomorphic argument, by considering both anguiform and non-anguiform figures. This will provide a wider range of contexts than either Aelian or Harrison discuss. In doing so, I intend to consider the meaning of the bearded snake using a considerably larger range of sources, in order to give the best possible explanation for this unusual motif.</p>

Aerobics Movement Decomposition Action Teaching System Based on Intelligent Vision Sensor

With the development of the times, teaching has not only stayed between people, but also gradually developed into the teaching interaction between man and machine. In the past, the teaching form was relatively single and old. Based on the intelligent visual sensor, this paper develops an auxiliary teaching system for the decomposition of aerobics action and reasonably uses the Internet and algorithms to catalog a series of aerobics action systems into the system. The DTW dynamic motion matching algorithm of the system will recognize human actions more accurately. The system will feed back human actions to the system in real time based on human feature recognition. Then, after comparison, the system will display the standard posture of this action and the aerobics posture in the next step. Therefore, this system develops teaching not only in class, but everywhere. The system not only improves the teaching quality of aerobics, but also strengthens the physical quality of teenagers. It has a new understanding of the standardization of aerobics teaching. After the function of the system is complete, the system will be distributed to aerobics learners. In many feedback information, the average use satisfaction has reached about 80%, which is a good performance index for the performance of the system itself.

Cancer Type Classification Using Plasma Cell Free RNAs Derived From Human and Microbes

Background: The utilities of cell free nucleic acids in monitoring cancer have been recognized by both scientists and clinicians. In addition to human transcripts, a fraction of cell free nucleic acids in human plasma were proved to derived from microbes, and reported to have some relevance to cancer. Methods: To get a better understanding of plasma cell free RNAs (cfRNAs) in cancer patients, we profiled cfRNAs in ~300 plasma samples of five cancer types (colorectal cancer, stomach cancer, liver cancer, lung cancer, esophageal cancer) and healthy donors with RNA-seq. Results: Microbe derived cfRNAs were consistently detected by different computational methods when potential contaminations were carefully filtered. Clinically relevant signals can be identified from human and microbial reads, and alteration in human cfRNA expression and virus abundance both suggests some cancer patients were immunosuppressed, as indicated by enriched KEGG pathways of downregulated human genes and higher prevalence torque teno virus. Our data supports the diagnostic value of human and microbe derived plasma cfRNAs for cancer detection, as an area under receiver operating characteristic (ROC) curve of 0.931 for distinguishing cancer patients from healthy donors was achieved on validation set, using both human and microbial features. Moreover, these cfRNAs both have some cancer type specificity, and could distinguish tumors of different primary locations. Compared to using human feature alone, combining human and microbial features improves the average validation accuracy of between cancer type classification by 11.5%. Conclusions: In summary, this work provides evidence for the clinical relevance of human and microbe derived plasma cfRNAs, and their potential utilities in cancer detection, and determination of tumor sites.

Extraction of Posture Silhouettes using Human Posture Feature Points and Spatial Masks for Activity Recognition in Public Place

Presently, an automated system has been required for public place security. Recognizing human postures in public places has emerged as a global solution for understanding human behavior in public places. In this work, a model to extract a human feature attribute of its posture has been presented to identify human behavior. The research work in this paper focuses on identifying the seating and standing postures of a person. The proposed methodology aims towards extraction of the human attributes from public places using spatial masks. Consequently, in this process, unwanted details from the background have been removed using the technique to focus on human postures only. The feature extraction process gives us blob vector and posture vector to evaluate human authentication and posture apprehension.

Hyper-altruistic behavior vanishes with high stakes

Using an incentivized experiment with statistical power, this paper explores the role of stakes in charitable giving of lottery prizes, where subjects commit to donate a fraction of the prize before they learn the outcome of the lottery. We study three stake levels: 5€ (n = 177), 100€ (n = 168), and 1,000€ (n = 171). Although the donations increase in absolute terms as the stakes increase, subjects decrease the donated fraction of the pie. However, people still share roughly 20% of 1,000€, an amount as high as the average monthly salary of people at the age of our subjects. The number of people sharing 50% of the pie is remarkably stable across stakes, but donating the the whole pie–the modal behavior in charity-donation experiments–disappears with stakes. Such hyper-altruistic behavior thus seems to be an artifact of the stakes typically employed in economic and psychological experiments. Our findings point out that sharing with others is a prevalent human feature, but stakes are an important determinant of sharing. Policies promoted via prosocial frames (e.g., stressing the effects of mask-wearing or social distancing on others during the Covid-19 pandemic or environmentally-friendly behaviors on future generations) may thus be miscalibrated if they disregard the stakes at play.

The Difficult Integration between Human and Animal Studies on Emotional Lateralization: A Perspective Article

Even if for many years hemispheric asymmetries have been considered as a uniquely human feature, an increasing number of studies have described hemispheric asymmetries for various behavioral functions in several nonhuman species. An aspect of animal lateralization that has attracted particular attention has concerned the hemispheric asymmetries for emotions, but human and animal studies on this subject have been developed as independent lines of investigation, without attempts for their integration. In this perspective article, after an illustration of factors that have hampered the integration between human and animal studies on emotional lateralization, I will pass to analyze components and stages of the processing of emotions to distinguish those which point to a continuum between humans and many animal species, from those which suggest a similarity only between humans and great apes. The right lateralization of sympathetic functions (involved in brain and bodily activities necessary in emergency situations) seems consistent across many animal species, whereas asymmetries in emotional communication and in structures involved in emotional experience, similar to those observed in humans, have been documented only in primates.

Deep Neural Networks Learn by Using Human-Selected ECG Features and Novel Features

Aims We sought to investigate whether artificial intelligence (AI) and specifically deep neural networks for electrocardiogram (ECG) signal analysis can be explained using human selected features. We also sought to quantify such explainability and test if the AI model learns features that are similar to a human expert. Methods We used a set of 100,000 ECGs that were annotated by human explainable features. We applied both linear and nonlinear models to predict published ECG AI models output for the detection of patients' age and sex. We further used canonical correlation analysis to quantify the amount of shared information between the features found in an unsupervised way. We reconstructed single human-selected ECG features from the unexplained neural network features using a simple linear model. Results We noticed a strong correlation between the simple models and the AI output (R2 of 0.49-0.57 for the linear models and R2 of 0.69-0.70 for the nonlinear models). We found that the correlation of the human explainable features with either 13 of the strongest age AI features or 15 of the strongest sex AI features was above 0.85 (for comparison, the first 14 principal components explain 90% of the human feature variance). We linearly reconstructed single human-selected ECG features from the AI features with R2 up to 0.86. Conclusion This work shows that neural networks for ECG signals extract features in a similar manner to human experts and that they also generate additional novel features that help achieve superior performance.

Transfer of consciousness. Considering its possibility or fantasy from the religious and scientific perspectives

Ancient beliefs such as astral projection, human possession, abduction and other similar are not only universal, taught by all religions, but also used as premises for core believes/expectations, such as after-life, eternal damnation, reincarnation, and many others. Transferring Consciousness to a Synthetic Body is also a feature of interest in our actual knowledge, both religious as for science. If immortality were an option, would you take it into consideration more seriously? Most people would probably dismiss the question since immortality isn’t a real deal to contract. But what if having eternal life was a possibility in today’s world? The possibility of the transfer of human consciousness to a synthetic body can soon become a reality, and it could help the world for the better. Thus, until recently, the subject was mostly proposed by religion(s) and saw as a spiritual [thus, not ‘materially real’ or ‘forthwith accomplishable’] proposal therefore not really fully engaged or trust if not a religious believer. Now, technology is evolving, and so are we. The world has come to a point where artificial intelligence is breaking the boundaries of our perception of human consciousness and intelligence. And with this so is our understanding about the ancient question ‘who are we?’ concerning consciousness and how this human feature sticks to our body or it can become an entity beyond the material flesh. Without being exhaustive with the theme's development [leaving enough room for further investigations], we would like to take it for a spin and see how and where the religious and neuroscience realms intersect with it for a global, perhaps holistic understanding. Developments in neurotechnology favor the brain to broaden its physical control further the restraints of the human body. Accordingly, it is achievable to both acquire and provide information from and to the brain and also to organize feedback processes in which a person's thoughts can influence the activity of a computer or reversely.

The More Fertile, the More Creative: Changes in Women’s Creative Potential across the Ovulatory Cycle

Creative thinking is a defining human feature. It provides novel solutions and as such undoubtedly has contributed to our survival. However, according to signaling theory, creativity could also have evolved through sexual selection as a potential fitness indicator. In our study, we tested one implication of this theory. Specifically, we hypothesized that if creativity can serve as a signal of women’s fitness, then we should observe an increase in creative thinking in the fertile phase of the ovulatory cycle compared to other non-fertile phases. In our study (N = 751), we tested creative potential throughout the ovulatory cycle. We found a positive correlation between the probability of conception and both creative originality and flexibility. Importantly, we also tested the mediating role of arousal in the relationship between the probability of conception and creative thinking. The results of our study are discussed in terms of signaling theory, through which women advertise their fitness with their creativity.
