Production of {\pi}+ and K+ mesons in argon-nucleus interactions at 3.2 AGeV

First physics results of the BM@N experiment at the Nuclotron/NICA complex are presented on {\pi}+ and K+ meson production in interactions of an argon beam with fixed targets of C, Al, Cu, Sn and Pb at 3.2 AGeV. Transverse momentum distributions, rapidity spectra and multiplicities of {\pi}+ and K+ mesons are measured. The results are compared with predictions of theoretical models and with other measurements at lower energies.Comment: 29 pages, 20 figure

Interconnection of Educational and Professional Standards

The paper discusses some issues of existing norms and requirements to educational and professional activities. The required soft (non-technical), general professional and professional skills are prescribed by educational standards, job descriptions are regulated by professional standards. Higher education programs must provide quality professional skills. A mandatory assessment and monitoring of professional skills should become a powerful motivator for employees’ long-life learning and selfeducation. A criterion for assessing the quality of education is a graduate who works in the specialty and qualitatively fulfils the job responsibilities. The reference to the statistics in educational and budgeting spheres is used to raise the problem of practical compliance of educational standards and professional job functions. Educationalstandardsshouldspecifythejobsappropriateforthegraduate.The control over competence formation must ensure the qualitative qualification. The conclusion is made that an employer does not finds it beneficial to retrain a certified specialist. A graduate of higher educational institution should be able to immediately fulfill the duties stated in his job description. In all stages of their higher education program, students should learn by doing to enhance skills by action learning, which must be ensured by the educational institution. In this regard, internship curriculum should be constantly monitored and regularly updated. There is an urgent need for educators to take up part-time jobs with relevant non-educational organizations or to receive regular refresher training. As for engaging outside professionals from non-educational organizations, it could be considered only as exception. It is proposed to develop a separate educational standard for the training of lecturers of higher education, as teachers must master the methodology of teaching students. A standard to guide professional activities of lecturers should also be worked out and recommended for practical application. This standard should be an extension of the educational standard. The potential and viability of this study is proved by the draft educational standards that put educational skills in compliance with professional standards (job descriptions).The growing number of publications on harmonizing educational and professional standards is also an evidence of its topicality

GBTX emulator for development and special versions of GBT-based readout chains

The GBTX ASIC is a standard solution for providing fast control and data readout for radiation detectors used in HEP experiments. However, it is subject to export control restrictions due to the usage of radiation-hard technology. An FPGA-based GBTX emulator (GBTxEMU) has been developed to enable the development of GBT-based readout chains in countries where the original GBTX cannot be imported. Thanks to utilizing a slightly modified GBT-FGPA core, it maintains basic compatibility with standard GBT-based systems. The GBTxEMU also may be an interesting solution for developing GBT-based readout chains for less demanding experiments.Comment: Conference "22nd International Workshop on Radiation Imaging Detectors" (22nd IWoRID

Boosting Geranyl Diphosphate Synthesis for Linalool Production in Engineered Yarrowia lipolytica

Linalool is a pleasant-smelling monoterpenoid widely found in the essential oils of most flowers. Due to its biologically active properties, linalool has considerable commercial potential, especially in the food and perfume industries. In this study, the oleaginous yeast Yarrowia lipolytica was successfully engineered to produce linalool de novo. The (S)-linalool synthase (LIS) gene from Actinidia argute was overexpressed to convert geranyl diphosphate (GPP) into linalool. Flux was diverted from farnesyl diphosphate (FPP) synthesis to GPP by introducing a mutated copy of the native ERG20F88W−N119W gene, and CrGPPS gene from Catharanthus roseus on its own and as part of a fusion with LIS. Disruption of native diacylglycerol kinase enzyme, DGK1, by oligo-mediated CRISPR-Cas9 inactivation further increased linalool production. The resulting strain accumulated 109.6 mg/L of linalool during cultivation in shake flasks with sucrose as a carbon source. CrGPPS expression in Yarrowia lipolytica increased linalool accumulation more efficiently than the ERG20F88W−N119W expression, suggesting that the increase in linalool production was predominantly influenced by the level of GPP precursor supply
