The aim of this paper is to provide an overview of current knowledge concerning the late La Tène chronology in Bohemia and Moravia during the LT C2–D2 phases (150–0 BC) with an emphasis on developments in the latter stages of the La Tène occupation of the Middle Danube zone (LT D1b – LT D2). During the first century BC, specifically from the 70s and 60s BC onwards, a succession of events caused a rapid chain of reactions that resulted in the abandonment of the oppida and the replacement of the La Tène population in Bohemia by incomers of Germanic origin on the one hand, and a final rapid rise of the La Tène elites in the Middle Danube zone on the other. These processes are accompanied by a distinctive material culture of both local and external origin (Mediterranean and Germanic) and these objects tell us much about the society and its socio-economic strategies, distribution patterns and long-distance communication. The article does not aim to provide an historical account of the events that took place around the second half of the first century BC, such as Ceasar’s military campaigns against the Helvetians and in Gaul, the supposed participation of the Boii in these events, and the demise of the Celtic occupation of the Bratislava oppidum as a result of the (supposed) devastating incursion by the Dacians under the leadership of Burebista. The objective is to summarise what is known about the chronology of this turbulent period of the first century BC and to offer an archaeological overview of the developments of material culture in the Middle Danube zone.

Recent market studies show that the market for remote monitoring devices of different medical parameters will grow exponentially. Globally, more than 4 million individuals will be monitored remotely from the perspective of different health parameters by 2023. Of particular importance is the way of remote transmission of the information acquired from the medical sensors. At this time, there are several methods such as Bluetooth, WI-FI, or other wireless communication interfaces. Recently, the communication based on LoRa (Long Range) technology has had an explosive development that allows the transmission of information over long distances with low energy consumption. The implementation of the IoT (Internet of Things) applications using LoRa devices based on open Long Range Wide-Area Network (LoRaWAN) protocol for long distances with low energy consumption can also be used in the medical field. Therefore, in this paper, we proposed and developed a long-distance communication architecture for medical devices based on the LoRaWAN protocol that allows data communications over a distance of more than 10 km.

AbstractFor the effective bearer of P2P-type services, a P2P service bearer reorientation method for passive optical network for long-distance wide access based on P2P protocol message and wire-speed message identification is proposed. However, the reorientation method still has the possibility of relocation failure, so it is modified – that is, an improved P2P service bearer reorientation method based on optical line terminal (OLT) and optical network unit (ONU) cooperation. And the tool NS2 is used for network simulation analysis. Through simulation analysis, it is verified that the modified reorientation method improves the data traffic burden at the core network and at the OLT.

AbstractWe propose an architecture of quantum-error-correction-based quantum repeaters that combines techniques used in discrete- and continuous-variable quantum information. Specifically, we propose to encode the transmitted qubits in a concatenated code consisting of two levels. On the first level we use a continuous-variable GKP code encoding the qubit in a single bosonic mode. On the second level we use a small discrete-variable code. Such an architecture has two important features. Firstly, errors on each of the two levels are corrected in repeaters of two different types. This enables for achieving performance needed in practical scenarios with a reduced cost with respect to an architecture for which all repeaters are the same. Secondly, the use of continuous-variable GKP code on the lower level generates additional analog information which enhances the error-correcting capabilities of the second-level code such that long-distance communication becomes possible with encodings consisting of only four or seven optical modes.
