A new computational approach to quantum antennas based on first principle open stochastic quantum dynamics.<div><br></div><div>We develop a general computational approach for the analysis and design of quantum antenna systems comprised of coupled quantum dot arrays interacting with external fields and producing quantum radiation. The method is based on using the GKSL master equation to model quantum dissipation and decoherence. The density operator of a coupled two-level quantum dot (qbit) array, excited by classical external signals with variable amplitude and phase, is evolved in time using a quantum Liouville-like equation (the master equation). We illustrate the method in a numerical example where it is shown that manipulating the phase excitations of individual quantum dots may significantly enhance the directive radiation properties of the quantum dot antenna system<br></div>

This paper provides an extension for Hawking temperature of Reissner–Nordström-de Sitter (RN-DS) black hole (BH) with global monopole as well as [Formula: see text]D charged black hole. We consider the black holes metric and investigate the effects of quantum gravity ([Formula: see text]) on Hawking radiation. We investigate the charged boson particles tunneling through the horizon of black holes by using the Hamilton–Jacobi ansatz phenomenon. In our investigation, we study the quantum radiation to analyze the Lagrangian wave equation with generalized uncertainty principle and calculate the modified Hawking temperatures for black holes. Furthermore, we analyze the charge and correction parameter effects on the modified Hawking temperature and examine the stable and unstable condition of RN-DS BH with global monopole as well as [Formula: see text]D charged black hole.

We develop foundations for the emerging field of quantum antennas using relativistic quantum field theory. We show that the concept of "antenna" goes beyond electromagnetic waves. Any quantum radiation can be treated within quantum antenna theory, not only electromagnetic or acoustic radiation that dominated the field so far.

In recent years, the study of the functional state of the lungs has become a topical issue for urgent surgery. This is due to the fact that the lungs play an important role in the regulation of the inflammatory response, and in the body balance control. The aim of the study is to establish the detoxification and hemostasis-correcting lung ability in acute pancreatitis experimentally and clinically; to determine the effectiveness of quantum metabolic therapy in correcting lung functional status. Materials and Methods. The experiments were performed on adult dogs (n=30). The animals were divided into two groups: the first group (n=15) – a pancreatitis model, the second group (n=15) – a pancreatitis model with complex treatment, including quantum irradiation and remaxol. Forty patients with acute severe pancreatitis were examined clinically. They were also divided into two groups. Patients of the first group (n=20) were treated according to clinical guidelines, whereas patients of the second group (n=20) underwent complex treatment, including quantum irradiation and remaxol. The level of toxic products in arterial and venous blood and the state of the hemostatic system were determined. Results. Having analyzed the results of the study, the authors can claim that pancreas tissue injury in acute pancreatitis results in endogenous systemic inflammation, that is manifested in dysfunctional lung disorders, namely, a decrease in lung detoxification activity and impaired hemostasis-regulating ability. Complex treatment with quantum radiation and remaxol increases lung reserves, thus, resisting trigger damage agents. It is manifested in an increase in lung detoxification ability and less hemostasis defects. Conclusion. The inclusion of quantum radiation and remaxol in the complex therapy of acute pancreatitis is pathogenetically substantiated. Such a therapy decreases dysfunctional lung events, such as an increase in lung detoxification ability and a decrease in hemostasis defects. Keywords: acute pancreatitis, lungs, endotoxicosis, hemostasis. В последние годы изучение функционального состояния легких стало актуальным вопросом для ургентной хирургии. Это обусловлено тем, что легкие играют важную роль в регуляции воспалительного ответа, в поддержании гомеостатических констант. Цель исследования – в эксперименте и клинике при остром панкреатите установить детоксикационную и гемостазкорригирующую способность легких; определить эффективность квантово-метаболической терапии в коррекции их функционального статуса. Материалы и методы. Эксперименты поставлены на взрослых собаках (n=30). Две группы: первая (n=15) – модель панкреатита, вторая (n=15) – модель панкреатита, лечение комплексное, включающее квантовое облучение и ремаксол. Клинический материал – 40 пациентов с острым тяжелым панкреатитом. Первая группа (n=20) – лечение согласно клиническим рекомендациям, вторая группа (n=20) – лечение комплексное, включающее квантовое облучение и ремаксол. В артериальной и венозной крови определяли уровень токсических продуктов и состояние системы гемостаза. Результаты. Анализ результатов экспериментальной и клинической частей исследования дает основание утверждать, что поражение тканей поджелудочной железы при остром панкреатите приводит к явлениям эндогенного системного воспаления, проявлением которого являются дисфункциональные расстройства легких в виде снижения их детоксикационной активности и нарушения гемостазрегулирующей способности. Проведение комплексного лечения с включением квантового облучения и ремаксола увеличивает резервы легких для противостояния триггерным агентам повреждения, что проявляется повышением их детоксикационной способности и меньшими расстройствами в системе гемостаза. Выводы. Включение в комплексную терапию острого панкреатита квантового облучения и ремаксола патогенетически обосновано. При такого рода терапии дисфункциональные явления со стороны легких уменьшаются, частным проявлением является повышение их детоксикационной способности и уменьшение расстройств в системе гемостаза. Ключевые слова: острый панкреатит, легкие, эндотоксикоз, гемостаз.

Abstract In three-dimensional AdS space, we consider the gravitational collapse of dust shell and then investigate the quantum radiation from the collapsing shell by employing the functional Schrödinger formalism. In the formation of the BTZ black hole, the interior geometry of the shell can be chosen as either the massless black hole or the global AdS space. In the incipient black hole limit, we obtain the wave function exactly from the time-dependent Schrödinger equation for a massless scalar field. Then, we show that the occupation number of excited states can be written by analytic expressions, and the radiation temperature is in agreement with the Hawking temperature, irrespective of the specific choice of the interior geometries.
