Authors: Gomes Luisa Pereira de Oliveira Zanetti , Martins Camila Marinelli , Pacheco Elis Carolina , Avais Letícia Simeoni , Borges Pollyanna Kássia de Oliveira 
Published: February 2024

Abstract
Background The post-COVID-19 condition is a major modern challenge in medicine and has a high global impact on the health of the population.
Objective To determine the main neurological and neuropsychiatric manifestations after acute COVID-19 infection in South American countries.
Methods This is a systematic review study, registered on the PROSPERO platform following the PRISMA model. 4131 articles were found with the search strategies used. Neurological and neuropsychiatric manifestations were investigated in individuals three months or more after acute COVID-19 infection, and older than 18 years, including studies conducted in South American countries published between 2020 and 2022.
Results Six studies (four from Brazil and two from Ecuador) were analyzed. Regarding the type of study: three were cohorts, two were case reports, and one was cross-sectional. The main outcomes found were new pain (65.5%) and new chronic pain (19.6%), new headache (39.1%), daily chronic headache (13%), paresthesia (62%), in addition to neuropsychiatric diseases, such as generalized anxiety disorder (15.1%), post-traumatic stress syndrome (13.4%), depression and anxiety (13.5%), suicidal ideation (10.1%), and several cognitive disorders.
Conclusion Neurological and neuropsychiatric manifestations related to depression and anxiety, and cognition disorders are reported during the post-COVID-19 condition in South America. Symptoms associated with chronic pain appear to be associated with the condition. More studies on post-COVID-19 conditions are needed in the South America region.

Published: February 2024

Abstract
Objective Synovial chondromatosis (SC) is relatively rare, but it often occurs in large joints and can cause osteoarthropathic (OA) changes if left untreated. It is extremely rare for this condition to occur around the wrist joint. We present a case treated by osteophyte resection for restriction of the forearm rotation caused by SC and the resulting OA changes in the distal radioulnar joint (DRUJ).
Case Description A 50-year-old woman had progressive OA changes due to SC in the DRUJ, and restriction of forearm rotation. Thorough excision of SC and osteophytes through the dorsal and palmar approaches of the wrist improved the range of rotation of the forearm with no recurrence.
Literature Review Although there have been scattered reports of SC occurring in the DRUJ, there have been no reports of management for restriction of forearm rotation caused by OA changes.
Clinical Relevance For SC in DRUJ, it is important to make an early definitive diagnosis and perform a synovectomy to prevent the progression of OA changes. Osteophyte resection is effective in the treatment of restriction of the joint motion caused by secondary OA changes.

Published: February 2024

AbstractThe fast-paced advances of technology, including artificial intelligence (AI) and machine learning (ML), continue to create new opportunities for banks and other financial institutions. This study reveals the barriers to trust in AI by prudential banking supervisors (compliance with regulations). We conducted a qualitative study on the drivers for adoption of explainability technologies that increase transparency and understanding of complex algorithms (some of the underpinning legal principles in the proposed EU AI Act). By using human-centred and ethics-by-design methods coupled with interviews of the key stakeholders from Eastern European private and public banks and IT AI/ML developers, this research has identified the key challenges concerning the employment of AI algorithms. The results indicate a conflicting view of AI barriers whilst revealing the importance of AI/ML systems in banks, the growing willingness of banks to use such systems more widely, and the problematic aspects of implementing AI/ML systems related to their cost and economic efficiency. Keeping up with the complex regulation requirements comes at a significant cost to banks and financial firms. The focus of the empirical study, stakeholders in Ukraine, Estonia and Poland, was chosen because of the fact that there has been a sharp increase in the adoption of AI/ML models in this jurisdiction in the context of its war with Russia and the ensuing sanctions regime. While the “leapfrogging” AI/ML paths in each bank surveyed had its own drivers and challenges, these insights provide lessons for banks in other European jurisdictions. The analysis of four criminal cases brought against top banks and conclusions of the study indicate that the increase in predicate crimes for money laundering, constantly evolving sanctions regime along with the enhanced scrutiny and enforcement action against banks are hindering technology innovation and legal implications of using AI driven tools for compliance.
Geo-political vampirism: how and why has Western literary scholarship appropriated and then re-mythologised the socio-historical origins of the vampire?
Authors: Dalton A. J. 
Published: February 2024

AbstractThe article considers the claims of Western academics like Frayling (1992) that the literary vampire began with Polidori’s The Vampyre (1819). Crawford (2016) identifies a German literary vampire tradition existing one hundred years before Polidori, yet that work has strengthened Eurocentric claims concerning the literary vampire by academics like Bloom (2018). The article reviews Anatol’s (2022) challenge to the dominant position of Dracula in vampire criticism, Anatol identifying a literary tradition pre-dating Stoker, that tradition seeing the documenting of Caribbean vampire folklore by British colonialists/slave owners, travel writers and journalists. In sympathy with Anatol’s non-Eurocentric consideration, the article re-examines/disputes Western academia’s ‘mythology’ concerning the Villa Diodati (1816), when Lord Byron’s reading from the German Fantasmagoriana apparently inspired Polidori and Mary Shelley to write their novels. The article identifies an Ottoman literary tradition that directly influenced Byron’s 1813 poem ‘The Giaour’, his unfinished story ‘A Fragment’ (1819), and Stoker’s Dracula. The article explores Ottoman vampire (‘obur’) literature, starting with Celebi’s Book of Travels of 1666, which refers back to the fifteenth century ‘vampire fatwas’ in the Balkans under Ottoman rule. The article traces how the dominant Turkic languages of the region informed the proto-Albanian language, the ‘vampire’ (as both term and demonised ‘other’) entering Albanian folklore. The Ottoman empire declining, the rising Austro-Hungarian and then British empires appropriated the vampire westward, exoticising and demonising non-central Europeans. Finally, the article provides a post-colonial reading of Southey’s 1801 orientalist poem Thalaba the Destroyer, reading the first true ‘vampire’ in English literature.
Emergency resource allocation considering the heterogeneity of affected areas during the COVID-19 pandemic in China
Authors: Wang Yanyan , Lyu Mingshu , Sun Baiqing 
Published: February 2024

AbstractThe scientific allocation of emergency resources is crucial to ensure the success of COVID-19 relief operations. However, the heterogeneity of epidemic areas has an important impact on the allocation of emergency resources. Although it is a crucial topic, there has been limited research that considers the heterogeneity of affected areas in the emergency resource allocation. To bridge the gap, this study proposes a multi-period optimal allocation model of emergency resources considering the heterogeneity of affected areas, which aims to make the allocation of resources more equitable, efficient and economical. Then, a typical and representative case of emergency medical resource allocation in Hubei Province, China (where the epidemic occurred earlier and was seriously affected by COVID-19), was selected for a simulation study to verify the effectiveness and feasibility of the proposed model and method. The study finds that considering the heterogeneity such as disaster coefficient and demand urgency in different disaster stricken areas in emergency resource allocation can minimize the negative impact of resource shortfalls, especially in the early period of relief operations with insufficient resource supply. In addition, the proposed model can optimize multi-period emergency resource allocation by simultaneously considering time (efficiency criterion), cost (economic criterion), and loss(equity criterion), which is in line with the actual needs of emergency rescue to the COVID-19 epidemic. The results of this study can be effectively applied to the multi-period optimal allocation of emergency resources for large-scale public health emergencies, and providing insights for the government and relevant management departments to formulate emergency resource allocation policies and plans.
Expressive suppression in the 2019 anti-government social unrest in Hong Kong: its association with psychological distress
Authors: Tsang Chi-pui Ada , Wong Wai-lap Lance 
Published: February 2024

AbstractHong Kong experienced a large-scale anti-government social unrest in 2019. High levels of violence and severe vandalism were common during the unrest, which have seriously affected the psychological wellbeing of Hong Kong people. Research has shown that, during the unrest, Hong Kong people exhibited an elevated level of psychological and mental disturbances, and these disturbances are still observed after the unrest has subsided. To further illuminate how large-scale social unrests affect people’s psychological functioning, in this study we examined the association of expressive suppression, which is defined as consciously hiding and withholding one’s emotions, with psychological distress in the context of the unrest in Hong Kong. The mediating role of rumination was also explored. The study was conducted in early 2021. A sample of 84 participants who had experienced the unrest in 2019 were recruited. They completed an online questionnaire for this study. Results from path analyses revealed that expressive suppression related to the unrest was positively associated with anxiety, stress, and depressed mood, and these associations were significantly mediated by rumination. Our findings suggest expressive suppression may play an important role in accounting for the effect of socio-political turmoil on psychological disturbances, and future research should pay more attention to this variable for understanding how large-scale political and social unrests, especially those that involve serious political divides, leave their marks on civilians.
Editors and world Englishes
Authors: Law Favo Melanie Ann 
Published: February 2024

Abstract
The impact of editorial intervention on the language of published written texts has been the topic of a handful of
recent empirical investigations within the world Englishes paradigm. These studies have demonstrated that the linguistic changes
that editors make to texts written in world Englishes contexts are not as conservative or consistent as previously assumed, with
some scholars suggesting that the sociolinguistic profiles of such editors might account for the varying behaviours noted in the
corpus-based investigations. In this article, I build on recent arguments for a more considered view of the impact of editorial
intervention on the language of published written texts in world Englishes contexts by examining editors’ sociolinguistic profiles
and the overt norms they draw on in the course of their work to explore how they orient their normative behaviour and how this may
be related to the evolutionary development of their respective varieties.

Do it in a different way: use a TDS meter to determine the colour degradation of dye solutions
Authors: Wibowo Edy , Ulya Naily , Handayani Ismudiati Puri , Rokhmat Mamat , Sutisna  
Published: February 2024

Abstract
This study demonstrated how a dye solution’s per cent colour degradation (η) may be calculated using the total dissolved solids (TDS) meter. As test solutions, varied concentrations of the brilliant blue solutions were utilised. We compared the results of TDS meter readings for per cent degradation with those of standard spectrometer measurements. The results of our measurements agree with those of a spectrometer. Therefore, TDS meters can be used as an option to measure colour degradation, particularly in laboratories lacking a spectrometer, considering that the price of a TDS meter is much more affordable than that of a spectrometer. A TDS meter with high accuracy must be used for scientific purposes demanding highly precise measurement findings.

W cm−2. A versatile and compact solid target suitable for up to 0.05 Hz is presented which can operate in the challenging petawatt laser environment close to the laser-plasma interaction. Strips are spooled in a tape target system to deliver a solid density target to the laser focus for every shot. Results are presented for different tape materials and thicknesses, and a shot-to-shot standard deviation of the cut-off energy of 1.5% was obtained for Kapton reinforced aluminium tapes of 9 µm thickness. Experimental ion spectra are recorded by a Thomson Parabola Ion Spectrometer coupled with a scintillator screen; and an antenna array is used for the characterization of electromagnetic pulses. The results of both diagnostics show a good shot-to-shot stability of the system.
A low-side-lobe folded transmitarray antenna based on metasurface with independent amplitude/phase control

Published: February 2024

Abstract
In this paper, a low-side-lobe folded transmitarray antenna (LSLFTA) based on metasurface (MS) that can independently control amplitude and phase is proposed. An MS, composed of two vertically placed polarization gates, can realize the efficient reflection of y-polarized waves, efficient transmission of x-polarized waves, and independently control of phase and amplitude is designed for the top surface. A polarization conversion surface (PCS) using an open resonant ring that can efficiently achieve cross polarization conversion is presented. The feed antenna is placed on the center of the top surface to obtain an accurate electromagnetic amplitude distribution. To the best of our knowledge, our work is thus the first one to achieve low-side-lobe FTA. The LSLFTA operating at 14.5 GHz is fabricated and measured to verify the design. After adding amplitude modulation (Taylor distribution), the side lobe level (SLL) is 5.2 dB and 7.5 lower than that of only phase modulation in the yoz plane and xoz plane, respectively. The 3 dB gain bandwidth of the antenna is 19.4% (13.5∼16.4 GHz), and the maximum aperture efficiency is 25.8%. Our work is a promising candidate in the design of high-gain, low SLL, and low-profile antenna.
Giant and tunable photonic spin Hall effect in a parity-time symmetric structure with a Dirac semimetal material
Authors: Qi Song , Da Haixia , Yan Xiaohong 
Published: February 2024

Abstract
The optical parity-time (PT) symmetry structure can yield unique properties, including periodicity, discreteness, nonlinearity, and so on. However, the component materials in these PT symmetry structures have been primarily restricted by their lack of tunability. Here, by utilizing the external stimulus-dependent optical properties of the Dirac semimetal, we report the theoretical prediction of the large and controllable photonic spin Hall effect in the PT symmetry structure with the slab of the Dirac semimetal. We provide evidence that the PT symmetry structure with the Dirac semimetal exhibits a large spin shift as high as the half of the waist at a certain incident angle, which is the conventionally theoretical upper limit. Due to the exceptional points, the spin shift can be enhanced effectively. Furthermore, we unravel that a small change in the Fermi energy of the Dirac semimetal on the order of 0.01 eV is able to engineer both the magnitude and sign of the spin shift. In particular, there is a transition in the spectrum of the spin shift when we vary the Fermi energy of the Dirac semimetal, where the number of the spin shift peak changes from one to two. Our results reveal the interplay between the light and the PT symmetry structure with the Dirac semimetal, which offers the possibility of developing Dirac semimetal-based spin-dependent photonic devices.
Visualizing high-dimensional loss landscapes with Hessian directions
Authors: Böttcher Lucas , Wheeler Gregory 
Published: February 2024

Abstract
Analyzing the geometric properties of high-dimensional loss functions, such as local curvature and the existence of other optima around a certain point in loss space, can help provide a better understanding of the interplay between neural-network structure, implementation attributes, and learning performance. In this paper, we combine concepts from high-dimensional probability and differential geometry to study how curvature properties in lower-dimensional loss representations depend on those in the original loss space. We show that saddle points in the original space are rarely correctly identified as such in the expected lower-dimensional representations if random projections are used. The principal curvature in the expected lower-dimensional representation is proportional to the mean curvature in the original loss space. Hence, the mean curvature in the original loss space determines if saddle points appear, on average, as either minima, maxima, or almost flat regions. We use the connection between expected curvature in random projections and mean curvature in the original space (i.e. the normalized Hessian trace) to compute Hutchinson-type trace estimates without calculating Hessian-vector products as in the original Hutchinson method. Because random projections are not suitable for correctly identifying saddle information, we propose to study projections along the dominant Hessian directions that are associated with the largest and smallest principal curvatures. We connect our findings to the ongoing debate on loss landscape flatness and generalizability. Finally, for different common image classifiers and a function approximator, we show and compare random and Hessian projections of loss landscapes with up to approximately

Authors: Yang Biao , Li Yizhe , Hao Zhanzhou , Yin Bo , Yin Ling , Song Jialei 
Published: February 2024

Abstract
In this paper, we utilized an array of four high-speed cameras to capture intricate wing kinematics, allowing us to calculate flapping amplitudes, frequencies, wingtip velocities, the ratio of upstroke to downstroke duration, and the angles between the forewings and hindwings. Preliminary analysis revealed that bees typically perform at least 15 wingbeats before taking off, with wing stroke amplitudes exceeding 100 degrees and frequencies within the range of 220 to 260 Hz. Additionally, the maximum angle between the forewings and hindwings generally surpasses 50 degrees. The kinematic parameters of takeoff are distinctive, and the relationships among various kinematic parameters are presented in this paper. Of particular note is the variation in the angle between the forewings and hindwings, which increases and then decreases with changing wingbeat speeds. In addition, we reconstructed the kinematic model of the wing motion for computational fluid dynamics (CFD) simulation, which will further reveal the aerodynamic mechanisms involved.

Published: February 2024

Abstract
Due to different applications, the size, shape and surface state of the power supply on spacecraft vary greatly, but they all need to experience a harsh environment, such as extreme vacuum, cold and hot alternation. Therefore, it is necessary to undergo the thermal vacuum test on the ground. During the thermal vacuum test, the aerospace power supply products with different surface states have different internal temperature rise effects due to their own emissivity and absorption during testing. The higher the temperature rise effect, the lower the product reliability. Therefore, in order to reduce the temperature rise effect of products in the process of thermal vacuum test, the temperature rise effect of products with different surface states or the same surface state can be reduced by using different shading measures in the thermal vacuum test of products is analysed and verified by experiments. The test results show that the product with bright surface has lower temperature rise effect than the product with blackened surface, which can reduce the maximum temperature difference, enhance the uniformity of temperature field and enhance the reliability of the product. In addition, using measures such as covering the product with aluminized film or overhanging it can reduce the surface temperature difference, with the overhanging shade being more effective.
