Multitenancy in Single Instance of Data Persistence Service for Supporting Low-Code Platforms by Julio Gustavo Costa, Luiz Marcos Garcia Goncalves, Samuel Xavier-de-Souza

“…This approach, however, implies a mode of operation that is not the most mature among cloud computing providers, implying for each model a service instance running on the provider side. Here, we propose a data persistence service for these platforms that avoids code generation, since it interprets data models at runtime and operates in multi-tenant mode with a single service instance. …”

Problema protocronismului. Precizări by Edgar Papu

“…His idea about the Romanian aesthetic forms anticipating or preparing currents, motives or procedures that were later to be experienced and dealt with by the Western culture was published twice before (1977 and 1989), but this one is the first uncensored text diffused after the fall of the communist regime in Romania. Running chronologically, the paper starts with a 16th c. work – contemporary to Machiavelli’s The Prince (1513) – due to the Lord of Walachia, Néagoé Bassarab, entitled The Lectures meant for his son Theodosius (1519-1521), which establishes a canon of reigning principles and skills at hand to his heir to the throne, considered by the author Edgar Papu to anticipate the appearance of the Baroque type of “hombre secreto” described in the treaties of the Jesuit monk Baltasar Gracián, called El Discreto (1646) and Oráculo manual y arte de prudencia (1647). …”

Performance Analysis of Prefabricated Steel-Spring Floating-Slab Track and Its Application to Urban Express Rail Transit by Xudong Huang, Ping Li, Xinwei Luo, Liang Ling, Abdulmumin Ahmed Shuaibu, Zhiping Zeng

“…As thickness increases, vertical displacement of the rail increases slightly, and lateral stability increases, thereby slightly improving the vehicle’s running stability. (3) When the intercity electric multiple-unit train travels along the prefabricated steel-spring floating-slab-track bed at different speeds, the wheel-axle lateral force, wheel-rail vertical force, the derailment coefficient, the wheel-weight reduction rate, and the lateral acceleration of the vehicle body are all less than the specified limits of Chinese code, thus fully meeting the safety requirements of train operation. (4) Appropriately increasing the vertical-support damping of the floating slab can improve the vehicle’s vertical dynamic performance, reduce the vertical displacement of the rail, and lower the vibration response of the floating slab. (5) Adding side-mounted vibration isolators at the joint of the floating slab could greatly improve the stability of the floating slab itself and appropriately reduce the vehicle’s vertical vibration response. …”

Spectra Narrowing of a 976 nm High Power External-Cavity Semiconductor Laser Based on a Transmission Grating by Di Xin, Nihui Zhang, Lingqian Meng, Qinghao Zhao, Weiqiao Zhang, Fengxin Dong, Xuyan Zhou, Hongbo Zhang, Wanhua Zheng

“…Nevertheless, these lasers exhibit a wide gain bandwidth, short cavity length, and usually use the natural cleavage surface as the output window, resulting in a broad emitting spectrum in free-running state. We investigated a high-power narrow-linewidth 976 nm edge emitting broad area semiconductor laser (EEL) through external cavity feedback technology by employing a transmission grating as the dispersive element. …”
