Semantics and symbol grounding in Turing machine processes
The aim of the paper is to present the underlying reason of the unsolved symbolgrounding problem. The Church-Turing Thesis states that a physical problem,for which there is an algorithm of solution, can be solved by a Turingmachine, but machine operations neglect the semantic relationship betweensymbols and their meaning. Symbols are objects that are manipulated on rulesbased on their shapes. The computations are independent of the context, mentalstates, emotions, or feelings. The symbol processing operations are interpretedby the machine in a way quite different from the cognitive processes.Cognitive activities of living organisms and computation differ from each other,because of the way they act in the real word. The result is the problem ofmutual understanding of symbol grounding.The aim of the paper is to present the underlying reason of the unsolved symbolgrounding problem.

New technologies as prosthesis of cognitive system
The aim of the paper is to show the way in which human cognitive system uses external prostheses. Currently developed technologies provide human beings with tools that change their way of functioning in the environment, their understanding and the perspective from which they perceive the world. Modifying systems of thoughts, reasoning and modes of operation non‑biological prostheses extend human cognitive system. A human being uses non‑biological interfaces for processing information from the external world.The aim of the paper is to show the way in which human cognitive system uses external prostheses.

Próby aplikacji paradygmatu ucieleśnionego umysłu w tworzeniu sztucznej inteligencji
Despite some significant achievements in the early stage of works on the development of artificial intelligence, scientists failed to program machines to imitate human thinking. The next generation of scientists included proposals of the embodied mind paradigm in their new research programme. The paradigm states that human intelligence is formed through a reciprocal interaction between the body and an environment. This work discusses the application of the main proposals of the new artificial intelligence that were applied in the process of constructing machines and modelling their behaviour. It presents important projects that met the philosophical criteria and that were aimed at embodying artificial intelligence.Despite some significant achievements in the early stage of works on the development of artificial intelligence, scientists failed to program machines to imitate human thinking.

Post-mortem detection of six human herpesviruses (HSV-1, HSV-2, VZV, EBV, CMV, HHV-6) in trigeminal and facial nerve ganglia by PCR
Background Among over 100 types of Herpesviridae viruses, eight can infect humans: herpes simplex viruses (HSV-1, HSV-2), varicella zoster virus (VZV), cytomegalovirus (CMV), Epstein-Barr virus (EBV), and human herpesviruses 6, 7, and 8 (HHV-6, HHV-7, HHV-8). After initial infection, the viruses remain latent for the lifetime of the host. The aim of this study was to determine the distribution of six different herpesviruses: HSV-1, HSV-2, VZV, EBV, CMV, and HHV-6 in trigeminal and facial nerve ganglia among a random group of Polish population. Methods The studied group consisted of 47 individuals (40 male, seven female); mean age of 47.4 ± 16.5 years) who died of independent causes (suicide, traffic accident, and poisoning, among others). Bilateral trigeminal and facial nerve ganglia of each cadaver were collected during the autopsy. Herpesviruses were detected using multiplex polymerase chain reaction technique. Results Herpesviruses were found in trigeminal and/or facial ganglia in 30/47 (63.8%) of cadavers. HHV-6 was the most prevalent of the herpesviruses and was found in nearly half of cadavers (n = 22; 46.8%), followed by HSV-1 (n = 7; 14.9%), VZV (n = 4; 8.5%), EBV (n = 4; 8.5%), HSV-2 (n = 2; 4.3%), and CMV (n = 1; 2.1%). Facial nerve ganglia (n = 23; 48.9%) were more often infected than trigeminal ganglia (n = 13; 27.7%). Discussion The results of this study have revealed a common presence of the herpesviruses in trigeminal and facial nerve ganglia among a random group of Polish population. Furthermore, the data also demonstrate simultaneous infection of the ganglia with different herpesviruses. This study has contributed to the knowledge of prevalence and localization of herpesviruses in different structures of the nervous system
AI is a viable alternative to high throughput screening: a 318-target study
: High throughput screening (HTS) is routinely used to identify bioactive small molecules. This requires physical compounds, which limits coverage of accessible chemical space. Computational approaches combined with vast on-demand chemical libraries can access far greater chemical space, provided that the predictive accuracy is sufficient to identify useful molecules. Through the largest and most diverse virtual HTS campaign reported to date, comprising 318 individual projects, we demonstrate that our AtomNet® convolutional neural network successfully finds novel hits across every major therapeutic area and protein class. We address historical limitations of computational screening by demonstrating success for target proteins without known binders, high-quality X-ray crystal structures, or manual cherry-picking of compounds. We show that the molecules selected by the AtomNet® model are novel drug-like scaffolds rather than minor modifications to known bioactive compounds. Our empirical results suggest that computational methods can substantially replace HTS as the first step of small-molecule drug discovery
The role of biosemiosis and semiotic scaffolding in the processes of developing intelligent behaviour
Biosemiotics deals with the processes of signs in all dimensions of nature. Semiosis is the primary form of intelligence. Intelligent behaviour becomes immediately understandable in this approach because semiosis combines causality with the triadic structure of the semiotic sign. Intelligence is a process created in a given context. In the course of evolution organisms have learned to create increasingly sophisticated internal representations of external state. Semiosis is the precursor of the emergence of a feature we consider intelligence. Biosemiotics also draws attention to the distributed intelligence, which relies on external semiotic scaffoldings as much as on the subject’s abilities and knowledge
