Published: January 2024

AbstractConsidering the importance of the renewable energy sector in the distribution systems, energy operation, and management which are connected to the distribution network (DN) in the form of multiple microgrids (MMGs) is crucial in reducing cost and pollution. Hence, this paper aims to propose optimal energy management for MMGs in the DN. Different objective functions have been taken into account in this optimization, including network cost, pollution reduction, and distribution network power losses. To design the multi‐objective optimization problem, a fuzzy method has been adopted for simultaneous multi‐objective calculations. Furthermore, the effect of the placement of distributed generations (DGs) and microgrids (MGs) is considered to reduce the distribution network power losses. Information gap decision theory (IGDT) has formulated uncertainties about renewable sources and consumers. To solve this optimization problem, a new method of the modified Harris Hawk optimization (MHHO) algorithm has been implemented, compared with the original HHO and genetic algorithm (GA). Finally, the proposed method has been analysed under the IEEE 33‐bus distribution network for a 24‐hour time horizon, including three MGs considering different renewable energy sources (RESs). The simulation results have demonstrated the high performance of the allocated network with the MHHO algorithm compared to the other scenarios.

AbstractA visible light positioning (VLP) system for multi‐cell networks based on multi‐colour LED that combines frequency division multiplexing with the received signal strength and a trilateration method is proposed. First, it employs experimental measurements to model the designed visible light communication (VLC) system under the characteristics of the target scenario. Second, it introduces a low‐cost VLC transmitter that exploits the chromatic space to transmit the VLP information. Third, it characterizes the VLC transmitter and proposes a linearization for electro‐optical responses of RGB LED. An RGB digital colour sensor and simple method calibrate the chromatic emission. The experimental results show that the proposed VLP multi‐cell architecture achieves a positioning accuracy lower than .
A new method for instrumental profile reconstruction of high-resolution spectrographs
Authors: Milaković D. , Jethwa P. 
Published: January 2024

Context. Knowledge of the spectrograph’s instrumental profile (IP) provides important information needed for wavelength calibration and for the use in scientific analyses.
Aims. This work develops new methods for IP reconstruction in high-resolution spectrographs equipped with astronomical laser frequency comb (astrocomb) calibration systems and assesses the impact that assumptions on the IP shape have on achieving accurate spectroscopic measurements.
Methods. Astrocombs produce ≈ 10 000 bright, unresolved emission lines with known wavelengths, making them excellent probes of the IP. New methods based on Gaussian process regression were developed to extract detailed information on the IP shape from these data. Applying them to HARPS, an extremely stable spectrograph installed on the ESO 3.6m telescope, we reconstructed its IP at 512 locations of the detector, covering 60% of the total detector area.
Results. We found that the HARPS IP is asymmetric and that it varies smoothly across the detector. Empirical IP models provide a wavelength accuracy better than 10m s−1 (5m s−1) with a 92% (64%) probability. In comparison, reaching the same accuracy has a probability of only 29% (8%) when a Gaussian IP shape is assumed. Furthermore, the Gaussian assumption is associated with intra-order and inter-order distortions in the HARPS wavelength scale as large as 60 m s−1. The spatial distribution of these distortions suggests they may be related to spectrograph optics and therefore may generally appear in cross-dispersed echelle spectrographs when Gaussian IPs are used. Empirical IP models are provided as supplementary material in machine readable format. We also provide a method to correct the distortions in astrocomb calibrations made under the Gaussian IP assumption.
Conclusions. Methods presented here can be applied to other instruments equipped with astrocombs, such as ESPRESSO, but also ANDES and G-CLEF in the future. The empirical IPs are crucial for obtaining objective and unbiased measurements of fundamental constants from high-resolution spectra, as well as measurements of the redshift drift, isotopic abundances, and other science cases.
Mechanical strength distribution in Geminid meteoroids derived via fireball modeling
Authors: Henych Tomáš , Borovička Jiří , Vojáček Vlastimil , Spurný Pavel 
Published: January 2024

Context. Geminids are the most active annual meteor shower observed on Earth. Their parent is an active asteroid, (3200) Phaethon, which is a target of the planned DESTINY+ mission of the Japan Aerospace Exploration Agency (JAXA). The exact physical nature of (3200) Phaethon and Geminids is still debated.
Aims. This paper is devoted to fragmentation modeling of bright Geminid fireballs, which should reveal information about the structure of centimeter-sized Geminid meteoroids. These fireballs were observed by the European Fireball Network (EN) over the past few years. We aim to describe their disintegration cascade in the atmosphere and their mechanical properties, and to derive their precise initial masses and velocities.
Methods. We used a semi-empirical fragmentation model that employs an automatic procedure based on parallel genetic algorithms to determine the aerodynamic pressures at which a meteoroid and its parts fragment. This serves as a proxy for the mechanical strength of the body and its subsequent fragments. It enabled us to derive the minimum, median, and maximum mechanical strength and the strength distribution inside the meteoroid and reveal its internal structure.
Results. We find that the Geminids begin to crumble at pressures 1–100 kPa, with the strongest parts reaching pressures of between 0.4 and 1.55 MPa before fragmenting. Knowing the spectral type of (3200) Phaethon (a B-type asteroid, part of the C complex), we conclude that the Geminids are made of compact and coherent carbonaceous material. We also find that the minimum aerodynamic pressure that causes the fragmentation of Geminids increases with increasing entry mass of Geminids. In contrast, the median aerodynamic pressure decreases as their entry mass increases. The spectra of all the observed Geminid fireballs show normal content and little variation in terms of sodium.
Confirmatory Factor Analysis of the Hyperacusis Impact Questionnaire, Sound Sensitivity Symptoms Questionnaire, and Screening for Anxiety and Depression in Tinnitus, Including Preliminary Analyses of the Parent Versions for Use with Children

Published: January 2024

Abstract
Background We previously reported the results of exploratory factor analysis (EFA) of the Hyperacusis Impact Questionnaire (HIQ), the Sound Sensitivity Symptoms Questionnaire (SSSD), and the Screening for Anxiety and Depression in Tinnitus (SAD-T). Confirmatory factor analysis (CFA) is necessary to confirm the latent constructs determined using EFA. CFA should use different samples but with similar characteristics to those used for EFA.
Purpose The aim was to use CFA to confirm latent constructs derived using EFA of the HIQ, SSSQ, and SAD-T. We further evaluated the psychometric properties of parent versions of these questionnaires (indicated by -P), which are intended for use with children.
Research Design This was a retrospective cross-sectional study.
Study Sample Data for 323 consecutive adults and 49 children who attended a Tinnitus and Hyperacusis Therapy Clinic in the United Kingdom within a 6-month period were included.
Data Collection and Analysis Data were collected retrospectively from the records of patients held at the Audiology Department. CFA with the weighted least-squares mean and variance-adjusted estimator was applied to assess the previously proposed factor structures of the HIQ, SSSQ, and SAD-T. The internal consistency of the scales was assessed via Cronbach's α (α). The items of the HIQ, SSSQ, and SAD-T were tested for measurement invariance regarding age and gender using the multiple indicator multiple cause (MIMIC) model.
Results All questionnaires showed good to excellent internal consistency, with α = 0.93 for the HIQ, 0.87 for the SSSQ, and 0.91 for the SAD-T. The parent versions showed acceptable to good internal consistency, with α = 0.88 for the HIQ-P, 0.71 for the SSSQ-P, and 0.86 for the SAD-T-P. CFA showed that the HIQ, SSSQ, and SAD-T were all one-factor questionnaires and the factors generally were similar to those obtained for the EFA. The MIMIC model showed that all three questionnaires can be considered as measurement invariant, with scores similar across genders and ages.
Conclusion The HIQ, SSSQ, and SAD-T are internally consistent one-factor questionnaires that can be used in clinical and research settings to assess the impact of hyperacusis, the severity of sound sensitivity symptoms, and to screen for anxiety and depression symptoms. Future studies should further explore the psychometric properties of the parent versions of the HIQ, SSSQ, and SAD-T.

Published: January 2024

Abstract
Purpose Vertebral compression fractures (VCFs) are common and associated with high morbidity including severe, debilitating pain. Percutaneous vertebroplasty/kyphoplasty is a demonstrated effective treatment for VCF. Sarcopenia has been implicated as a risk factor for VCF and refracture following cement augmentation, and as a risk factor for procedural complications in some populations; however, the effect of sarcopenia on VCF patients undergoing these procedures is unknown. This study aims to improve outcomes and patient selection by investigating the effects of highly common VCF comorbidities.
Methods A retrospective study was performed of all patients who underwent vertebroplasty/kyphoplasty for treatment of VCF at a single center from 2007 to 2020. Sarcopenia was quantified by normalized total psoas area (TPA) as measured on computed tomography. The effect of sarcopenia, bone density t-score, and clinical and demographic covariates on periprocedural pain scores was evaluated with linear mixed-effects models.
Results Out of 458 procedures performed, 146 and 130 were included in the sarcopenia and osteoporosis analyses, respectively. Sarcopenia and osteoporosis were highly comorbid in VCF patients undergoing vertebroplasty/kyphoplasty. Linear mixed-effects modeling showed no significant association between change in pain score and TPA score (p = 0.827) or bone density t-score (p = 0.818).
Conclusion Postprocedural pain reduction after vertebroplasty/kyphoplasty is not associated with the presence or severity of sarcopenia or osteoporosis/osteopenia. Appropriate patient selection remains critical to optimize the risk–benefit ratio of vertebroplasty/kyphoplasty, and sarcopenia and osteoporosis should not be considered contraindications to these procedures.
Facial phantom model: a low-cost and safe tool for teaching botulinum toxin application in neurology residencies
Authors: Alencar e Silva Rodrigo , Fraiman Pedro , Godeiro Júnior Clécio de Oliveira 
Published: January 2024

Abstract
Background The application of botulinum toxin (BoNT) in the treatment of blepharospasm and hemifacial spasm (HS) is a well-established practice. However, neurology residency programs often rely on real patients for training, which has limitations in terms of patient availability and skill acquisition.
Objective Assess the efficacy of a new facial phantom model for acquiring motor skills in BoNT application.
Methods An anthropomorphic facial phantom model was developed in collaboration with a medical training simulator start-up. A group of seven neurologists and one ophthalmologist with expertise in BoNT application evaluated the model using an adapted learning object review instrument (LORI). The instrument assessed aspects such as: content quality, alignment of learning objectives, feedback and adaptation, motivation, presentation design, and accessibility.
Results The facial phantom model received high scores in the LORI evaluation, with the highest ratings given to alignment with learning objectives and motivation. The model also scored well in terms of accessibility, content quality, and presentation design. However, feedback and adaptation received a lower score due to the static nature of the model.
Conclusion The facial phantom model shows promise as a valuable tool for teaching and developing competence in BoNT application for HS and blepharospasm. The model reduces the reliance on real patients for training, providing a broader and safer learning experience for neurology residents. It also provides a realistic learning experience and offers portability, cost-effectiveness, and ease of manufacturing for use in various medical training scenarios. It is an effective and accessible tool for teaching BoNT application.

Published: January 2024

Abstract
Background Phantom limb pain (PLP) occurs after amputations and can persist in a chronic and debilitating way. Repetitive transcranial magnetic stimulation (rTMS) is a non-invasive neuromodulation method capable of influencing brain function and modulating cortical excitability. Its effectiveness in treating chronic pain is promising.
Objective To evaluate the evidence on the efficacy and safety of using rTMS in the treatment of PLP, observing the stimulation parameters used, side effects, and benefits of the therapy.
Methods This is a systematic review of scientific articles published in national and international literature using electronic platforms.
Results Two hundred and fifty two articles were identified. Two hundred and forty six publications were removed because they were duplicated or met the exclusion criteria. After selection, six studies were reviewed, those being two randomized clinical trials and four case reports. All evaluated studies indicated some degree of benefit of rTMS to relieve painful symptoms, even temporarily. Pain perception was lower at the end of treatment when compared to the period prior to the sessions and remained during patient follow-up. There was no standardization of the stimulation parameters used. There were no reports of serious adverse events. The effects of long-term therapy have not been evaluated.
Conclusion There are some benefits, even if temporary, in the use of rTMS to relieve painful symptoms in PLP. High-frequency stimulation at M1 demonstrated a significant analgesic effect. Given the potential that has been demonstrated, but limited by the paucity of high-quality studies, further controlled studies are needed to establish and standardize the clinical use of the method.
Bisexuality in experimental sociophonetics
Authors: Willis Chloe 
Published: January 2024

Abstract
The belief that there is a relationship between sexuality and speech has inspired a vast body of linguistic
research on lesbian- and gay-sounding voices (Campbell-Kibler 2007, Gaudio 1994, Levon 2006, Moonwomon-Baird 1997, Munson, McDonald, DeBoe & White
2006a, Munson, Jefferson & McDonald 2006b, Pierrehumbert, Bent, Munson, Bradlow & Bailey 2004, Smyth, Jacobs
& Rogers 2003, Zimman 2013). Bisexuality is conspicuously absent in this
literature. This article analyzes bisexual English speakers’ productions of the voiceless alveolar fricative /s/ relative to
lesbian, gay, and straight speakers using linear mixed-effects regression modeling. A qualitative analysis of post-test
participant information surveys contextualizes the statistical findings. The quantitative and qualitative results suggest that
bisexual women and men do not pattern consistently with each other or lesbian, gay, or straight speakers. The analysis highlights
the extent to which ideologies of sexuality, gender, and normativity inform experimental sociophonetic research practice.
Cross-cultural code-switching for sexuality professionals
Authors: Levand Mark A. , Moreno Lorena Olvera , Sitron Justin 
Published: January 2024

Abstract
Sexuality professionals (sexologists) often communicate from a broad perspective of sexuality based on unique
training. Cross-cultural code-switching is useful for sexologists to communicate with those who have different sexological
worldviews. We discuss the concept of cross-cultural code-switching and its usefulness for sexuality professionals. We consider
the theories behind the usefulness of this tactic in one’s work as a sexologist and offer practical considerations for effective
code-switching across cultures. We observe the power dynamics in code-switching and offer this theoretical work as a way to raise
one’s awareness to these realities of communication in the roles sexuality professionals hold in the world.
“Like little Helsinki girls in the backseat of a tram”
Authors: Lindeman Meri 
Published: January 2024

Abstract
This article explores the conceptions and attitudes that non-linguists have towards Finnish spoken by gay men.
Combining folk linguistics and feminist theories, the study utilises interview and survey data for content analysis. The study
finds that the main characteristics of speech viewed as “gay” – e.g. high pitch, atypical intonation patterns, nasality,
non-canonical /s/ quality, use of affective adjectives – align with the speech stereotypes associated with girls
and young women. The article suggests that, even though the attitudes explicitly communicated by the participants are mostly
neutral, the language features associated with gay men show a strong relation to extra-linguistic gay stereotypes.
Sequentiality
Authors: Campbell Akua 
Published: January 2024

Abstract
This paper examines a hitherto unreported use of the Gã Perfect gram termed the ‘sequential perfect’. The sequential perfect represents a late stage of grammaticalization as it no longer conveys any aspectual information on its own, instead deriving its semantics from verbal categories in the prior discourse. It is primarily modal, being used for irrealis, habitual and iterative situations. It occurs in the non-initial clause of multiclausal constructions and signals that the event it marks is temporally posterior to another event. It also imparts the epistemic modal meanings of inevitability and certainty. I propose that these newer functions are developed from the core semantic components of change-of-state and completion. This involves grammaticalization via domain extension, where change-of-state within an event is extended to change between events. The investigation introduces a new pathway for grammaticalization of the perfect, which has implications for studies of the perfect and grammaticalization generally.
Thermodynamics and optical properties of phantom AdS black holes in massive gravity
Authors: Jafarzade Kh , Eslam Panah B , Rodrigues M E 
Published: January 2024

Abstract
Motivated by high interest in Lorentz invariant massive gravity models known as dRGT massive gravity, we present an exact phantom black hole solution in this theory of gravity and discuss the thermodynamic structure of the black hole in the canonical ensemble. Calculating the conserved and thermodynamic quantities, we check the validity of the first law of thermodynamics and the Smarr relation in the extended phase space. In addition, we investigate both the local and global stability of these black holes and show how massive parameters affect the regions of stability. We extend our study to investigate the optical features of the black holes such as the shadow geometrical shape, energy emission rate, and deflection angle. Also, we discuss how these optical quantities are affected by massive coefficients. Finally, we consider a massive scalar perturbation minimally coupled to the background geometry of the black hole and examine the quasinormal modes by employing the WKB approximation.
