Authors: Kondo Tomohiro , Nozaki Takamu , Kotabe Ryuya , Terai Yoshikazu 
Published: December 2022

Abstract
Bismuth selenide (Bi2Se3) epitaxial films were grown at different substrate temperatures (T
s) by molecular beam epitaxy. In the optimization of T
s, a Bi2Se3 film with the smallest root mean square roughness (Rq) and the lowest electron density was grown at T
s = 120 °C. In the optimized growth condition, Bi2Se3 epitaxial films with 3−85 quintuple layers (QL: 1 QL ≈ 1 nm) were grown. In unpolarized Raman spectra, the positions of A

g-modes shifted to the low wavenumbers at film thickness below 10 QL. The polarized Raman spectra showed that the depolarization ratio ρ also changed with film thickness. The change in ρ was more significant than the change in the position shift. This indicates that the measurement of ρ is an effective method to evaluate the thickness of Bi2Se3 ultrathin films.
Spatio-temporal description of the origin of optical-near-field interactions
Authors: Yazaki Tomoaki , Kobayashi Kiyoshi , Ishikawa Akira 
Published: December 2022

Abstract
Optical-near-field interactions occur via virtual photons that are non-resonant with the nanomaterials. Since the virtual photon exists only on a timescale shorter than the timescale of the interaction between the propagating light and the nanomaterial, the optical-near-field interactions exhibit non-Markovian temporal properties. We propose the spatio-temporal description of excitation transfer dynamics via virtual photons, and clearly show that the spatial properties of optical-near-field interactions at a short distance originate from the non-Markovian temporal properties on short timescale. Thus, the origin of optical-near-field interactions can be understood using the spatio-temporal description of the non-Markovian dynamics.
Thermal defect healing of single-walled carbon nanotubes assisted by supplying carbon-containing reactants

Published: December 2022

Abstract
We experimentally investigated the effect of carbon-containing reactants (C2H2) on healing the defects in single-walled carbon nanotubes (SWCNTs) by thermal processes at high temperatures (∼1100 °C). Introducing C2H2 notably improved the crystallinity of healed SWCNTs compared with the thermal process in Ar ambient without C2H2. The defect healing rate increased with increasing C2H2 partial pressure, and the healing effect of C2H2 was more remarkable for relatively thinner SWCNTs (<1.1 nm). Combined with the relevant theoretical work reported previously, we propose a healing model in which C2H2 helps to heal the vacancy defects and increases the healing rate at high temperatures.

Published: December 2022

The purposeof this study is a comparative analysis of data on the yield of surimi minced meat from some types of cod fish based on the results of experimental and control work (ECW).Methods used:experimental and control work was carried out according to the «Methods for determining the consumption rates of raw materials in the production of products from hydrobionts». Calculations of experimental and control work results were performed using software for processing the results in the production of frozen surimi minced meat. 12 ECW were carried out (4 ECW for each type of fish), while 22,150 kg of pollock, 33,400 kg of far eastern goby and 20,650 kg of saffron cod were directed to the production of surimi minced meat.Novelty:on the basis of the research and development work carried out, data were obtained on the yield of surimi minced meat from cod fish, made on a modern line in the conditions of a coastal enterprise. It has been established that the yield of surimi minced meat from pollock according to the results of ECW is on average 2,0 % higher than the values obtained for the far eastern goby and saffron cod.Result:an analysis of the modern production of surimi minced meat was carried out, which indicates a trend towards expanding the raw material base for its production due to fish with a high fat content and dark meat color, including warm-water ones; objects of pond aquaculture; low-value and small-s ized fish, which to a certain extent helps to reduce the cost of the finished product. However, pollock 35–45 cm in size is the most preferred raw material for obtaining high-quality «surimi» with a high yield, high degree of whiteness and the ability to form a strong gel.Practical significance:the results obtained allow us to determine current trends and prospects for the use of pollock for the manufacture of fish food products of deep processing. The unique properties of surimi minced meat and the increase in its production will expand the range of easily digestible fish protein products for various population groups.

A Review of Current-Limiting Control of Grid-Forming Inverters Under Symmetrical Disturbances
Authors: Fan Bo , Liu Teng , Zhao Fangzhou , Wu Heng , Wang Xiongfei 
Published: December 2022

<p>Grid-forming (GFM) inverters are recognized as a viable solution to increase the penetration of renewable energy in bulk power systems. However, they are physically different from synchronous generators in terms of overcurrent capability. To protect the power semiconductor devices and support the power grid under severe symmetrical disturbances, the GFM control systems should be able to achieve the following requirements: current magnitude limitation, fault current contribution, and fault recovery capability. Various current-limiting control methods are reported in the literature to fulfill these goals, including current limiters, virtual impedance, and voltage limiters. This paper presents an overview of those methods. Emerging challenges that need to be addressed, including temporary overcurrent, unspecified output current vector angle, undesired current saturation, and transient overvoltage, are pointed out. Comparative simulations are conducted to demonstrate the performance of different methods under grid voltage drops and phase jumps. Finally, open issues of current-limiting control methods for GFM inverters, including transient stability assessment, voltage source behavior under overcurrent conditions, and windup of voltage controllers, are shared. </p>
A Self-Solving Approach to Ordinary Differential Equations
Authors: Kennedy Stephen 
Published: December 2022

<p>A novel approach for numerical analysis of ordinary differential equations (ODEs) is shown to cause an arbitrary initial function to conform to the solutions of sample ODEs. By way of examples, the method is shown to consistently converge upon the solutions of initial value problems for two different step sizes. Further study is needed to determine if the method is stable for increasing smaller step sizes. Some advantages of this method are its simplicity, new approach to solving problems, and its potential to be applicable to a wide range of ODEs and partial differential equations that are useful in STEM fields. </p>
PUNK E HIP-HOP COMO MOVIMENTOS SOCIAIS?
Authors: Turra Neto Nécio 
Published: December 2022

Abordo aqui duas culturas juvenis transterritoriais – Punk e Hip-Hop –, problematizando a possibilidade de considerá-las como novos sujeitos políticos, territorializados no lugar. Inicio o texto situando o conjunto de preocupações, que tem direcionado minha atenção: as relações entre sociabilidade e cidade, no espaço-tempo. Punk e Hip-Hop colocam-se como possibilidades de identificação para jovens, situados em diversos lugares da cidade, construírem suas redes de sociabilidade e territorializarem-se na cidade. Uma territorialização que não é indiferente à cidade concreta em que se realiza. Assim, argumento que a consideração do Punk e do Hip-Hop como movimentos sociais só pode se dar a partir de parâmetros muito precisos. Para referendar o argumento, reconstruo a trajetória histórica de ambas as culturas juvenis, do mundo ao lugar, tomando como referência uma cidade média paranaense. Para finalizar, apresento uma reflexão, ainda preliminar, sobre a dialética socioespacial, tema para o qual estudos dessa natureza podem trazer alguma contribuição.
