Published: December 2023

AbstractThe battery energy storage system (EES) deployed in power system can effectively counteract the power fluctuation of renewable energy source. In the planning and operation process of grid side EES, however, the incorporation of power flow constraints into the optimization problem will strongly affect the solving efficiency. Therefore, a bi‐level planning and operation co‐optimization model for EES is proposed based on a constraint boundarization technique. Firstly, a constraint boundarization method for considering power flow constraints is proposed to solve the efficiency problem of the optimization model. Secondly, in terms of the upper and lower bounds of storage's operation curve obtained by the constraint boundarization method, an operation risk evaluation index is defined to describe the potential risk of storage planning scheme. Thirdly, this paper establishes a bi‐level planning and operation co‐optimization model for EES, in which the planning problem with a goal of minimizing total cost is taken as an outer layer and the operation problem for pursuing renewable energy consumption and reducing the load curtailment is taken as an inner layer. Finally, case studies are carried out, and results demonstrate the feasibility and effectiveness of the proposed model and method.

AbstractThis study aims to develop an optimization strategy for determining the optimal type and capacity of batteries in a building‐applied photovoltaic system, taking into account battery degradation, consumption profiles, and regional solar irradiation. Key performance indicators such as peak shaving, savings, net present value, self‐consumption, return on investment, and payback period are examined. The best trade‐off among these indicators is determined using the fuzzy decision‐making method. A study was conducted using real data from Kpenergy Company, focusing on a building with a 50 kW photovoltaic system located in Stockholm. Three cases were examined in MATLAB software, each categorized based on the type of contract between the utility (Vattenfall Company) and the subscriber. The results of these case studies highlight the effectiveness of the proposed optimization approach. Using the proposed approach, optimal batteries are determined, minimizing subscriber costs while maximizing profit.
Event‐triggered distributed secondary control for enhancing efficiency, reliability and communication in island mode DC microgrids

Published: December 2023

AbstractAlthough distributed secondary control helps control microgrids, it can provide insufficient performance in some cases where the system includes both renewable energy sources (RESs) and energy storage systems (ESSs). Therefore, an improved distributed secondary control structure is proposed in this study to improve efficiency and reliability in island mode DC microgrids that include RESs and ESSs. In order to regulate the power flow in accordance with the real time generation of the sources, maximum power calculation algorithms have been created within the secondary control levels of the PV and wind controllers. Furthermore, a fuzzy logic‐based energy management system has been designed in the secondary control of the battery controller to manage the power flow of the whole system considering the battery charge states and the total power generated by RESs. The distributed secondary control operates in event‐triggered mode to reduce the communication burdens. To avoid zeno behavior, event‐triggered control is designed based on sampled data. The proposed control scheme has been tested in Simulink environment and its stability is verified using Lyapunov's stability criteria. Results show that the power demand is successfully provided proportionally among the RESs and the communication burden is reduced considerably.
A bipolar structure and shocks surrounding the stellar-merger remnant V1309 Scorpii
Authors: Steinmetz T. , Kamiński T. , Schmidt M. , Kiljan A. 
Published: December 2023

Context. V1309 Sco is an example of a red nova, a product of the merger between non-compact stars. V1309 Sco is particularly important within the class of red novae due to the abundance of photometric data of the progenitor binary before the merger.
Aims. We aim to investigate the spatio-kinematic and chemical properties of the circumstellar environment, including deriving the physical conditions and establishing the origins of the different circumstellar components.
Methods. We used radiative transfer modelling of molecular emission in sub-millimetre spectra to examine the properties of the molecular gas, and we used forbidden line diagnostics from optical spectra to constrain the electron density and temperature using forbidden line diagnostics. We compared line intensities from shock models to observations to look for and constrain shocks.
Results. We derived a new kinematical distance of 5.6 kpc to the source. The detection of ro-vibrational H2 and sub-millimetre HCO+ emission in 2016 and 2019, respectively, indicate active shock interactions within the circumstellar environment. The velocity profiles of both H2 and HCO+, as well as the moment-1 maps of sub-millimetre CO and 29SiO, indicate a bipolar structure that may be asymmetric. The sub-millimetre and optical molecular emission exhibits temperatures of 35–113 and 200 K, respectively, whilst the atomic gas is much hotter, with temperatures of 5–15 kK, which may be due to shock heating.
Conclusions. The detection of a bipolar structure in V1309 Sco indicates further similarities with the structure of another Galactic red nova, V4332 Sgr. It provides evidence that bipolar structures may be common in red novae. All collected data are consistent with V1309 Sco being a kinematically and chemically complex system.

Low-temperature antihydrogen atoms are an effective tool to probe the validity of the fundamental laws of Physics, for example the Weak Equivalence Principle (WEP) for antimatter, and -generally speaking- it is obvious that colder atoms will increase the level of precision.
After the first production of cold antihydrogen in 2002 [1], experimental efforts have substantially progressed, with really competitive results already reached by adapting to cold antiatoms some well-known techniques pre- viously developed for ordinary atoms. Unfortunately, the number of antihydrogen atoms that can be produced in dedicated experiments is many orders of magnitude smaller than of hydrogen atoms, so the development of novel techniques to enhance the production of antihydrogen with well defined (and possibly controlled) conditions is essential to improve the sensitivity.
We present here some experimental results achieved by the AEgIS Collaboration, based at the CERN AD (Antiproton Decelerator) on the production of antihydrogen in a pulsed mode where the production time of 90% of atoms is known with an uncertainty of ~ 250 ns [2]. The pulsed antihydrogen source is generated by the charge-exchange reaction between Rydberg positronium (Ps*) and an antiproton (p¯): p¯ + Ps* → H¯* + e−, where Ps* is produced via the implantation of a pulsed positron beam into a mesoporous silica target, and excited by two consecutive laser pulses, and antiprotons are trapped, cooled and manipulated in Penning-Malmberg traps. The pulsed production (which is a major milestone for AEgIS) makes it possible to select the antihydrogen axial temperature and opens the door for the tuning of the antihydrogen Rydberg states, their de-excitation by pulsed lasers and the manipulation through electric field gradients.
In this paper, we present the results achieved by AEgIS in 2018, just before the Long Shutdown 2 (LS2), as well as some of the ongoing improvements to the system, aimed at exploiting the lower energy antiproton beam from ELENA [3].

Published: December 2023

ResumoBifosfonatos são amplamente usados no tratamento da osteoporose; porém, predispõem ao surgimento de fraturas atípicas. A região subtrocantérica femoral é usualmente acometida, mas outros ossos também são afetados. Fraturas atípicas da tíbia em pacientes portadores de gonartrose grave são um desafio terapêutico. O presente trabalho relata o caso de uma paciente idosa com gonartrose avançada que apresentou fratura atípica tibial. A paciente fazia uso prolongado de bifosfonatos para osteoporose, com quadro de dor e limitação funcional decorrentes da gonartrose, que progrediu para dor súbita na metáfise tibial à direita, impedindo a deambulação. Radiografias evidenciaram artrose grave bilateral; varismo acentuado; erosão medial tibial e femoral; e fratura no terço proximal da diáfise tibial direita. Trataram-se a fratura e a artrose à direita por osteossíntese com placa bloqueada e artroplastia total do joelho com estabilização posterior e base fixa. Após reabilitação física, relatou-se melhora significativa da dor e da função, readquiriu-se a marcha independente e alcançou-se arco de movimento de 0 a 100°. Após um ano, as radiografias mostraram consolidação da fratura e alinhamento satisfatório dos eixos dos membros inferiores. A coexistência de artrose grave e fratura atípica dificultou o tratamento. Contudo, o resultado foi satisfatório e a abordagem com osteossíntese e artroplastia simultâneas mostrou-se adequada.

Published: December 2023

AbstractWith the widespread use of radio-frequency identification (RFID) technology as a means for commerce and identification, new types of cybercrime have emerged. Accordingly, revisions to extant cybercrime law are required. This research attempts to determine the relevance of current UAE laws in addressing new cybercrimes on emergent technologies. We reviewed the literature to identify threats to RFID systems, classifying works into three categories: blocking, interception, and physical attacks. We mapped these categories to 50 articles of the UAE cybercrime law to assess their relevance. According to the distribution of law articles pertaining to RFID attacks, it was found that RFID communication interception attacks are not sufficiently addressed in the law and that further amendments are required in the UAE. Example of international statutes are highlighted as models.
What kind of discipline are we? A network analysis of British Politics
Authors: Byrne Christopher , Randall Nick 
Published: December 2023

AbstractResearch on British politics has traditionally been too reliant on a single model for understanding its field of inquiry—initially the Westminster model and then, since the 2000s, the governance-focused ‘differentiated polity model’. It has also been criticised for being preoccupied by the institutions that make up the Westminster system in terms of its substantive analytical focus, neglecting theory and international comparisons, failing to learn from other disciplines, and neglecting issues of age, gender, ethnicity and the environment (Marsh in Br Polit 7:43–54, 2012; Randall in Br Polit 7:17–29, 2012; BJPIR in Br J Polit Int Relat 24:3–10, 2022). This article aims to substantiate some of these claims using a network analysis of articles published in the journal British Politics to illuminate the who and the what of contemporary British politics research: Who authors it, which communities they form, what topics they focus on, and how they relate to the rest of the discipline. The evidence presented paints a picture of a valuable, but also still somewhat insular and fragmented discipline, and one that is itself inflected by structured inequalities.
Exploring the influence of teachers’ motivating styles on college students’ agentic engagement in online learning: The mediating and suppressing effects of self-regulated learning ability
Authors: Li Suqi , Xu Kexue , Huang Jun 
Published: December 2023

AbstractOnline learning has gradually become the new mainstream learning norm during the post-epidemic era. To ensure college students’ online learning effectiveness, they need to be proactively engaged in their online learning, which means that they need to maintain a high level of agentic engagement. However, it is not clear what factors influence college students’ agentic engagement in online learning environments. According to self-determination theory (SDT), the teacher, as an important external factor, can influence students’ learning engagement and learning effectiveness. Meanwhile, self-regulated learning (SRL) ability is important for college students in online learning. Based on existing theoretical foundations, therefore, the current study attempts to explore the following research questions: Are there relationships between teachers’ motivating styles (including autonomy-supportive style and controlling style), college students’ online SRL ability, and college students’ online learning agentic engagement? If yes, how does the former influence college students’ online learning agentic engagement? To respond to these research questions, random sampling was used to collect a total of 681 valid data from college students with experience in online learning. Then, a pilot test, exploratory factor analysis, and confirmatory factor analysis were first conducted to confirm the reliability and validity of the data. Correlational and mediating analyses were then conducted using SPSS 21.0. According to the results, firstly, teachers’ motivating styles (autonomy-supportive style and controlling style) and college students’ online SRL ability were positively correlated with college students’ online agentic engagement. Secondly, teachers’ autonomy-supportive style was positively correlated with college students’ online SRL ability, but the controlling style was negatively correlated with their online SRL ability. What’s more, college students’ online SRL ability, as a mediating factor, acted as a partial mediation between autonomy-supportive style and college students’ online agentic engagement, and there was a suppressing effect of college students’ SRL ability between teachers’ controlling style and college students’ agentic engagement. The results imply that teachers should choose motivating styles appropriately based on students’ online learning characteristics and content, and college students should develop online SRL ability to improve their agentic engagement and ultimately achieve good online learning effectiveness.
Measurement of droplet gravity-induced mechanical force by optofluidic microbottle resonator with lever model

Published: December 2023

Whispering gallery mode resonators provide an intriguing platform for precision measurement due to their high responsivity and low detection limit. Here, we propose and demonstrate an optofluidic microbottle resonator (OFMBR) that is utilized to measure droplet gravity-induced mechanical force, realized by establishing a lever model between tapered fiber and OFMBR. The mechanical force can be amplified by adjusting the ratio of the load arm to the effort arm of the lever, which is validated by theoretical simulation. The evolved mechanical force deforms OFMBR morphology and enhances light scattering, resulting in mixed variations in the transmission spectrum, including resonance wavelength, mode linewidth, and signal intensity. Experimentally, the mechanical force is first measured by monitoring resonance wavelength shift, and a responsivity of −56 pm/mN is obtained within the range of 0–0.2 mN. Furthermore, to monitor the mixed variations in the transmission spectrum and obtain the actual mechanical force directly, the optical barcode method is utilized to simultaneously monitor the variations of multimode features. The arbitrary unknown mechanical force is determined by the cross correlation function, and the measurement resolution is about 5 µN. Our scheme provides a thread for characterizing the liquid properties and investigating the dynamics at solid–liquid interfaces.

Published: December 2023

Interfacial water is ubiquitous on Earth, playing a crucial role in biology, chemistry, physics, materials science, and environmental science. Multiscale, hierarchical water motions on the surface of different materials under different conditions (temperature, hydration extent, pressure, etc.) and the coupling of this motion with the substrate/solute dynamics and the influence of these couplings on the material functions are complex, long lasting, interdisciplinary research topics. We herein focus on the coupling between the picosecond dynamical onset of substrates and their surface water at temperatures lower than the freezing point (273 K) and discuss the recent progress in the study of its molecular mechanisms.
