Opis:
The task of the ship immune system is to differentiate self objects, i.e. objects that are not dangerous to our ship, from other objects that can be a potential threat. To perform the task the system makes use of a set of detectors. The detectors imitate signatures of non-self objects and they are generated at random. In order for the detectors to be able to effectively perform their task they have to be constructed in appropriate way. Since, random generators are used to form detectors the problem is to select a generator producing the most effective detectors. In order to select an appropriate generator, experiments were carried out. In the experiments, the task of the ship immune system was to differentiate self and non-self ship radio stations. Results of the experiments are presented at the end of the paper.

Opis:
This research aims to determine the best currents speed and utilization of venturi to increasing survival, growth of Cyprinus carpio L. and reducing the infection rate of A. hydrophila bacteria. fingerlings. This research used an experimental method completely randomized design (CRD) with four treatments and four replications. The treatments used were the use of currents and venturi on the maintenance media with currents velocities of 0 m/s (A), 0.06 m/s (B), 0.1 m/s (C), and 0.14 m/s (D). Maintenance of the test fish for 40 days then followed by a challenge test for 14 days. Koi fish fingerlings tested to use A. hydrophila with a density of 108 CF /ml. The parameters observed included white blood cells, red blood cells, clinical symptoms, survival, daily growth rate, feed conversion ratio and water quality. The results showed that the use of currents and venturi with a flow rate of 0.14 m/s was effective in improving the performance of the koi fish's immune system and reducing the infection rate of A. hydrophila bacteria. During the flow administration during the 40 days maintenance period, the white blood cell count increased by 20.51% from a value of 9.19 × 104 cells/mm3 to 11.56 × 104 cells/mm3. Red blood cells increased by 40.65% from 1.60 × 106 cells/mm3 to 2.69 × 106 cells/mm3. Currents treatment with a speed of 0.14 m/s produced the highest survival rate after challenged with a value of 86.7%. Also this treatment was effective in preventing infection of A. hydrophila bacteria, it can be seen from the macroscopic clinical symptoms that appear less than the treatment current. The best results of daily growth rate and feed conversion ratio provided in currents treatment with a speed 0.1 m/s.

Opis:
The task of Ship Immune System is to differentiate self objects, i.e. objects that are not dangerous to our ship, from other objects that can be a potential threat. To identify objects, the system uses specially constructed detectors. Each detector imitates a non-self object. If an object is similar to a least one detector it is considered to be non-self one. Otherwise, it is treated as self one. The detectors can be represented in the form of real or integer valued vectors. In the paper, the latter solution is discussed. To test Ship Immune System, equipped with integer valued detectors, experiments were carried out. In the experiments, the task of the system was to differentiate self ship radio stations from non-self ones. Results of the experiments are presented at the end of the paper.
Zadaniem Okrętowego Systemu Immunologicznego jest odróżnianie obiektów własnych, czyli takich, które nie stanowią zagrożenia dla naszej jednostki, od wszystkich pozostałych obiektów określanych jako obiekty obce. Do identyfikacji obiektów używane są detektory z których każdy imituje jeden obiekt obcy. W przypadku kiedy niezidentyfikowany obiekt jest podobny do co najmniej jednego detektora, traktowany jest on przez system jako obiekt obcy, w przeciwnym przypadku uznaje się, że mamy do czynienia z obiektem własnym. Detektory systemu mogą być reprezentowane w postaci wektorów rzeczywistoliczbowych lub całkowitoliczbowych. W niniejszym artykule zaprezentowano drugie z wymienionych rozwiązań. W celu zbadania efektywności systemu immunologicznego wyposażonego w detektory całkowitoliczbowe przeprowadzono eksperymenty w trakcie których identyfikacji podlegały radiostacje okrętowe. Wyniki eksperymentów zaprezentowano w artykule.

Opis:
The immune system of the vertebrates possess the capabilities of “intelligent” information processing, which include memory, the ability to learn, to recognize, and to make decisions with respect to unknown situations. The mathematical formalization of these capabilities forms the basis of immune-computing (IC) as a new computing approach that replicates the principles of information processing by proteins and immune networks. This IC approach looks rather constructive as a basis for a new kind of computing. With the Morphotronic System or the analogous SVD we can create effective learning process and create immune memory by the projection operators. Given the immune memory is possible to recognize and compare antigen in a way to take defense action to eliminate the dangerous cell.

Opis:
Biologically inspired computing that looks to nature and biology for inspiration is a revolutionary change to our thinking about solving complex computational problems. It looks into nature and biology for inspiration rather than conventional approaches. The Human Immune System with its complex structure and the capability of performing pattern recognition, self-learning, immune-memory, generation of diversity, noise tolerance, variability, distributed detection and optimisation - is one area that has been of strong interest and inspiration for the last decade. An air conditioning system is one example where immune principles can be applied. This paper describes new computational technique called Artificial Immune System that is based on immune principles and refined for solving engineering problems. The presented system solution applies AIS algorithms to monitor environmental variables in order to determine how best to reach the desired temperature, learn usage patterns and predict usage needs. The aim of this paper is to explore the AIS-based artificial intelligence approach and its impact on energy efficiency. It will examine, if AIS algorithms can be integrated within a Smart Air Conditioning System as well as analyse the impact of such a solution.

The task of the ship immune system is to differentiate self objects, i.e., objects that are not dangerous for our ship, from other objects that can be a potential threat. To perform the task, the system makes use of a set of detectors. The detectors imitate signatures of non-self objects, however, to generate them the signatures of self objects are used. Real signatures of non-self objects are usually unobtainable and therefore they are not used to produce the system. However, situations sometimes happen when the information about non-self objects is accessible. In such a case, the information mentioned can be used to improve performance of the system. To test the ship immune system build based on signatures of both self and non-self objects, experiments were carried out. In the experiments, the task of the system was to differentiate self ship radio stations from non-self ones. Results of the experiments are presented at the end of the paper.
Zadaniem okrętowego systemu immunologicznego jest rozróżnianie obiektów własnych, nie stanowiących zagrożenia dla okrętu, od obiektów obcych które mogą być dla niego groźne. Do realizacji powyższego zadania system wykorzystuje zbiór detektorów. Detektory imitują sygnatury obiektów obcych, a do ich tworzenia wykorzystywane są sygnatury obiektów własnych zapamiętane w systemie. Ponieważ sygnatury obiektów obcych są zazwyczaj niedostępne, nie są one wykorzystywane w procesie tworzenia detektorów. Występują jednak sytuacje kiedy informacja o obiektach obcych jest dostępna podczas tworzenia systemu. Informacja ta może być wykorzystana do poprawienia jego efektywności. Artykuł przedstawia dwie metody umożliwiające wykorzystanie informacji o obiektach obcych podczas tworzenia detektorów. Obie metody zostały sprawdzone eksperymentalnie. Wyniki eksperymentów zostały przedstawione na końcu artykułu.

Opis:
Aim. Using available data from previously published study the hypothesis that individuals with broader disease history are more conservative than those, who were infected less often in the past was tested. Methods. Publicly available database containing data regarding perceived vulnerability to disease, social conservatism and participant’s history of parasitic disease was accessed. In the study 9409 cases from 43 countries were analysed.  Results. When controlling for participant’s age, sex, education level, wealth and perceived infectability, it was found, that broader disease history was a significant predictor of social conservatism. Conclusions. Individuals, who were in the past infected with parasitic diseases more often, were observed to be more conservative than people, who had suffered from these diseases less often.

Opis:
A basic mathematical model of the immune response when cancer cells are recognized is proposed. The model consists of six ordinary differential equations. It is extended by taking into account two types of immunotherapy: active immunotherapy and adoptive immunotherapy. An analysis of the corresponding models is made to answer the question which of the presented methods of immunotherapy is better. The analysis is completed by numerical simulations which show that the method of adoptive immunotherapy seems better for the patient at least in some cases.

Opis:
The human digestive system is colonized by a huge number of microorganisms, that are referred to collectively as the gut microbiota. The composition of intestinal microorganisms are shaped from an early life and undergoes constant changes depending on the influence of external factors, such as: type of delivery, feeding the young child, diet in subsequent years of life, pharmaceuticals use, stress, lifestyle or infections and previous inflammation within the digestive tract. Despite transient changes in microbiota composition, the intestinal ecosystem is constantly striving to maintain homeostasis, both qualitative and quantitative, which is fundamental to human health and human development. Microbes present in the intestines are responsible for sealing the intestinal barrier, mucin production, stimulation of the angiogenesis process, supporting digestive processes by fermentation and decomposition of undigested food residues, vitamin production or protection from pathogenic microorganisms. As shown by numerous studies carried out in recent years, intestinal dysbiosis plays a fundamental role in the development of many chronic diseases such as inflammatory bowel disease, diabetes, obesity, celiac disease, connective tissue diseases and others. Insightful understanding of the interactions between microorganisms and the host organisms can provide new information about pathogenesis of diseases as well as new ways to prevent and treat intestinal or systemic disorders. The aim of this work is to review the latest reports on the role of the gastrointestinal microbiome in selected chronic diseases.
