Abstract: Latest technologies in the field of neurosurgery maximize patient safety and improve treatment outcomes. These advances are integrated into all aspects of clinical care - from diagnosis through surgery, postoperative care and rehabilitation. The current review will outline recent neurosurgical advances in the management of brain tumors, movement disorders, spinal degenerative disease, neurologic injury, and the expanding area of brain-machine interface. It is a complex and multidisciplinary knowledge related to the nervous system with overlapping aspects which are closely interconnected to elementary professional subjects such as science, technology, engineering, and mathematics. For example, minimally invasive surgical techniques are a part of the daily practice of many spine surgeons. They aim less tissue damage, predictable clinical outcomes, shorter hospital stays and faster postoperative rehabilitation, clinical efficacy, and reasonable cost. Based on the facts that our specialty relies on meticulous motor skills to carefully manipulate vulnerable structure, work through narrow areas, and prolonged procedures with surgeon fatigue, it is a good candidate for robotic surgery. To support all the additive manufacturing regarding 3D printing, the related 3D scanning and work in extended reality environment is described as a feature of the third industrial revolution. We will broadly use anatomic haptic models for preoperative planning, surgical guides for the operative procedure, and patient-specific individual implants for tissue reconstruction.

Abstract: ZELLKRAFT is scientifically validated health training for targeted improvement of cellular metabolism. It functions exactly where a person's energy is created: in the powerhouses of the cell, the so-called mitochondria.
THIS MEANS: Improved performance, reduced recovery time, better memory, better sleep, better appearance through tighter skin and reduction of excess body weight. It is due to the release of various "good mood hormones" in the brain (neurotransmitters) that maintain mental balance.
THE METHOD: Targeted regeneration is at the heart of the ZELLKRAFT method. Energy production in the cells is enhanced by using high purity mountain air. This noticeably strengthens and revitalizes the entire body with all its organs and bodily functions. Through targeted additional measures in the field of fitness, nutrition and relaxation, the metabolism and cellular energy level are activated and restored in the long term.

Abstract: Fate is not always kind to seekers. The secrets of knowledge have never been hidden somewhere. But do we have the eyes to see them, the heart to feel them, and the mind to understand them, when the need to veer off the beaten and comfortable path overwhelms us. There are no ultimate truths, no fully described suffering or happiness, hope and disappointment will never cease to accompany us. That mystery of contemplating the starry sky and finding concrete earthly truths and technical solutions in infinity is a gift from God. We all know about the great discoveries, about the turning points in the development of civilization, science and technology. Aristotle, St. St. Cyril and Methodius, Galileo, Newton and Watt, Foucault and Lavoisier, Lobachevsky and Mendeleev, Poincaré, Gauss and Planck, Marconi and Tesla, Einstein and Freud, Nietzsche and Schopenhauer, Academician Pencho Slaveykov and Teodor Trayanov, Ivan Milev and Vladimir Dimitrov - Maistora, Yesenin and Acad. Sakharov, Acad. Bogdan Filov, John Atanasov, Acad. Balevsky and Acad. Sendov, etc., listing the names of these awakeners of the spirit and knowledge can be continued ad infinitum. For each one of them, we know how he reached and turned the invisible into the visible, the impossible into the possible, and gave us pieces of the future. And surely Leonardo da Vinci was right that in science the opinion of one is much more valuable than the convictions of thousands. Almost everything in engineering is borrowed from nature. However, there is one thing that is truly the pinnacle of human imagination and creative genius. This is the digital information - with only zeros and ones we control everything, really, absolutely everything! And without this "human" discovery, we will never create our best assistant - artificial intelligence. There is another miracle, but it is Bulgarian. This is our first and unsurpassed invention - the Bulgarian, our A a, B b, C c ..... The sacred symbols of the holy brothers Cyril and Methodius have given meaning to the power and culture of our great empire in the past, and now the progress that coming up.
It is not an exaggeration to say that what makes our lives more comfortable and meaningful is subject to invention. Technological solutions drive industry, finance, medicine, and all that we call the prosperity of individual countries. The more common word for the purpose is innovation or creativity. The simplest, but perhaps most accurate, definition of innovation is the transformation of the intellectual products contained in inventions into money, goods, and industrial development. This path is thorny for us. Not that bankers elsewhere give money easily for the transfer of patented technologies, but they are probably more risk-averse there.
My meeting with you is a kind of balance sheet - to present to the intellectual elite of Ruse the scientific and applied results that we managed to have today as particles or more precisely as dust particles from the future. The responsibility is huge, both to you and to the Taxpayer. Almost everything I'm about to tell you about is an invention. It was initially an idea, then it was theoretically researched and experimented to finally become a patent. We will talk about our innovations in sensors, robotics and metrology, airspace control, converting the energy of sea waves into electricity, earthquake prediction, smart agriculture and crop production, cyber-physical systems for national security, underwater devices for recreational tourism, etc.
