Twin-field quantum key distribution (TF-QKD) and its variants can overcome the fundamental rate-distance limit of QKD which has been demonstrated in laboratory field while their physical implementations with side channels remains to be further researched. We find external modulation different intensity states through test, required those TF-QKD post-phase compensation, shows a channel frequency...

generally speaking, tax is deemed as a manifestation of the government's authority and plays a key role in procuring public revenues, as the most critical factor. indeed, we might say, that continuity of the governmental activities depend on receiving taxes. thus, taxes occupy a high rank of importance in most of the countries, especially iran and england. therefore, lots of powers and privileg...

Proteins mediate transmission of signals along intercellular and intracellular pathways and between the exterior and the interior of a cell. The dynamic properties of signaling proteins are crucial to their functions. We discuss emerging paradigms for the role of protein dynamics in signaling. A central tenet is that proteins fluctuate among many states on evolutionarily selected energy landsca...

Rapid development of microelectronics during the past years allowed the emergence of high-performance implantable biomedical microsystems (IBMs). Nowadays, these systems share many features and basic components, and are being used in different applications such as neural signal recording, functional muscular stimulation, and neural prostheses. Due to implant size limitations in a wide range of ...

Most of the HVDC power converters with thyristor valves are assembled in a converter Bridge of Six pulse configuration. Converter transformers with one DC side winding as an ungrounded star connection and the other a delta configuration. Comparative studies of the two systems of HVDC CIGRE model without STATCOM and with STATCOM were performed. In these case, the consideration was the converter ...

Objectives:Hypertension is one of the most common diseases of the modern era. This study evaluates the effect of hydro-alcoholic celery leaf extract onsystolic blood pressure (SBP), heart rate (HR) and lipid profile in animals’ model of hypertension induced by fructose. Materials and Methods: Sprague Dawley rats were divided into five groups: 1) control group (free access to tap drinking water)...
