“A history lesson, perhaps, for my novice counterpart”
Authors: Mortazavi Seyed Mohammadreza , Zandi Hamed , Makki Mohammad 
Published: December 2023

Abstract
In this paper, we explore how (im)politeness and face are managed by two top diplomats of the US and Iran amidst
an ongoing conflict where both claim to occupy moral high grounds. To that end, 360 relevant tweets posted on the Iranian Foreign
Minister and US Secretary of State’s official accounts over one year were selected and analyzed qualitatively through the
theoretical lens of Culpeper’s (2011) impoliteness formulae and implicational
impoliteness framework. Three overarching pragmatic functions were identified: criticizing the adversary, giving directives, and
showing solidarity with allies while projecting a significant amount of face-threat to the adversary. We also identified three
main strategies that they used to justify their impoliteness, namely, appeal to the moral order, appeal to common sense, and
appeal to international conventions and regulations. These findings can contribute to impoliteness literature by providing
insights into the pragmatic functions and justifications in political communication, where the speakers have to balance their face
needs and their communicative goals.
DEMNUni: disentangling dark energy from massive neutrinos with the void size function
Authors: Verza Giovanni , Carbone Carmelita , Pisani Alice , Renzi Alessandro 
Published: December 2023

Abstract
Cosmic voids, the underdense regions in the Universe, are impacted by dark energy and massive neutrinos. In this work, relying on the DEMNUni suite of cosmological simulations, we explore the void size function in cosmologies with both dynamical dark energy and massive neutrinos. We investigate the impact of different choices of dark matter tracers on the void size function and study its sensitivity to the joint effect of several dark energy equations of state and total neutrino masses.
In particular, we find that for all the combinations of neutrino mass and dark energy equation of state considered, the differences between the corresponding void size functions are larger than the associated Poisson noise, and therefore can be all distinguished. This looks very promising considering that forthcoming surveys, as the Euclid satellite, will be characterised by a void statistics with similar number densities and volumes as for the DEMNUni suite. These findings show that the use of the void size function in forthcoming large galaxy surveys will be extremely useful in breaking degeneracies among these cosmological parameters.
Wavelength-stabilized figure-of-9 thulium-doped all-fiber laser emitting 560 fs pulses
Authors: Bartnick Moritz , Bharathan Gayathri , Goebel Thorsten A , Krämer Ria G , Nolte Stefan , Brés Camille-Sophie 
Published: December 2023

Abstract
We demonstrate a figure-of-9 all-fiber thulium-doped laser (TDFL) that generates 560 fs long pulses at 1948 nm wavelength. In order to achieve self-starting passive mode-locking, we utilize an in-fiber Faraday rotator to induce a nonreciprocal phase shift. To the best of our knowledge, this is the first all-fiber TDFL that combines an artificial saturable absorber (SA) with a chirped fiber Bragg grating (CFBG) as a wavelength-selective reflector. This cavity design is an excellent candidate to pump nonlinear processes such as supercontinuum and frequency comb generation since it does not require any SA material that degrades over time for mode-locking and could be made wavelength-tuneable via the CFBG.
Accuracy of numerical relativity waveforms with respect to space-based gravitational wave detectors
Authors: Wang Zun , Zhao Junjie , Cao Zhoujian 
Published: December 2023

Abstract
As with the laser interferometer gravitational-wave observatory (LIGO), the matched filtering technique will be critical to the data analysis of gravitational wave detection by space-based detectors, including LISA, Taiji and Tianqin. Waveform templates are the basis for such matched filtering techniques. To construct ready-to-use waveform templates, numerical relativity waveforms are a starting point. Therefore, the accuracy issue of numerical relativity waveforms is critically important. There are many investigations regarding this issue with respect to LIGO. But unfortunately there are few results on this issue with respect to space-based detectors. The current paper investigates this problem. Our results indicate that the existing numerical relativity waveforms are as accurate as 99% with respect to space-based detectors, including LISA, Taiji and Tianqin. Such an accuracy level is comparable to that with respect to LIGO.

Authors: Li Shengshan , Du Ming , Li Yanggui , He Jun , Ma Fuliang , Chen Qingyun 
Published: December 2023

Abstract
With the development of wind power generation units towards the mega-scale, the blade root and tower have large load and vibration problems during the operation of wind turbines. In order to extend the operational life of wind turbines, a PI independent pitch control (IPC) strategy with fuzzy adaptive tuning (FAT) is introduced based on the existing wind turbine model and control strategy to achieve optimal control of wind turbine loads. Simulations are carried out by the FAST software of the US Renewable Energy Laboratory to compare the independent pitch and the cooperative pitch. The results show that IPC reduces the load on the blade roots and improves the quality of the electrical energy.
Optimal Operation Strategy of Community Integrated Energy System Based on a Two-level Game
Authors: Wang Qinglin , Niu Huanna 
Published: December 2023

Abstract
With the gradual transformation of the integrated energy system to intelligence and decentralization, users with distributed generation gradually replace traditional users. To realize the rationality of multi-agent power transactions in a community-integrated energy system and improve the income of each subject in the system, this paper presents the optimal operation strategy of a community-integrated energy system based on the two-level game. The first layer is a cooperative game between energy communities, which can promote the consumption of new energy in communities. The second layer is a master-slave game between operators and communities, which can promote effective interaction between the upper and lower levels. By using the Karush-Kuhn-Tucker condition, the two-layer model is transformed into a single-layer model and uses McCormick to relax the model. The example verifies that the trading strategy proposed in this paper can effectively improve the benefits of each energy community.

Authors: Qiao Jian , Lu Qinghui , He Rufei , Ma Yiming , Yin Xianggen , Peng Yumin , Wang Wenhui , Zhang Hao 
Published: December 2023

Abstract
Aiming at the rotor eccentric fault modeling problem of large VSPSU (VSPSU), a mathematical analytical modeling method based on air gap magnetic field analysis is proposed. This method uses Fourier series decomposition to represent the air gap permeability of static and dynamic eccentricity faults. Then, taking a single coil as a unit, the eccentric self-inductance coefficients between each branch of the windings are derived. Furthermore, the mathematical analytical modeling of the eccentric fault is completed by combining the voltage and flux formulas of each winding branch. The model can reliably reflect the typical fault characteristics of large VSPSUs with eccentric faults, which can provide an analysis basis for subsequent relay protection research.
A technique for modeling and optimizing the design of wave energy conversion devices
Authors: Xia Chunqiu , Wang Tiancheng , Xu Duotian 
Published: December 2023

Abstract
With the continuous development of society and the economy, energy shortages have become increasingly prominent. As an important marine renewable energy source, wave energy holds significant theoretical significance due to its widespread distribution and vast storage potential. In this paper, we employ differential equation theory, numerical optimization methods, and optimization techniques to model and design algorithms for investigating the energy conversion mechanisms of wave energy devices. Due to the complex situation, we decided to simplify that into two scenarios. As to the first scenario, the essence of energy output in wave energy devices lies in the relative velocity between the floater and the oscillator. Firstly, the product of the damping force and the instantaneous relative velocity is integrated over time and divided by the period to obtain the average output power. Maximizing the average output power, with the damping coefficient as the decision variable, establishes a nonlinear optimization model. Secondly, a stepwise optimization approach is applied to control the damping coefficient, resulting in optimal damping coefficients of 33600, . Finally, a genetic algorithm is employed to validate the results as to the next scenario. After adding rotational dampers and torsion springs to the wave energy device, the relative velocity and relative angular velocity between the floater and the oscillator jointly contribute to energy output. The objective is to maximize the sum of the average output power of linear dampers and rotational dampers. The decision variables are the linear damping coefficient and the rotational damping coefficient. A nonlinear optimization model is established. A stepwise optimization approach is applied to optimize both types of coefficients, and the results are validated using a genetic algorithm. The optimal solution is found to have a linear damping coefficient of 60135.7781 N·s/m and a rotational damping coefficient of 4244.90358 N·s·m for the rotational dampers.

Authors: Qiu Xiaoying , Sui Yi , Zhang Yaozhong , Zheng Ping 
Published: December 2023

Abstract
Permanent magnet synchronous motor is often used as drive motors for electric vehicles. It is prone to demagnetization failure, and the change of permanent magnet flux link is an important basis for diagnosing demagnetization failure of the motor. First, the study establishes a permanent magnet flux adaptive observer and ensures its stability. Then the sensitivity analysis of the main parameters in the observer is carried out. For the parameter with high sensitivity and a large range of variation during motor operation, the expression of flux observation error caused by this parameter change is derived, and the gain matrix in the observation model is optimized. Through simulation verification, the observer can be used for the demagnetization fault diagnosis of the motor.

Jump effect of an eccentric cylinder rolling on an inclined plane
Authors: Aldo Arroyo E , Aparicio Alcalde M 
Published: December 2023

Abstract
This work addresses the intriguing phenomenon of the jump effect exhibited by an eccentric cylinder rolling on an inclined plane. Our main objective is to determine the region of the parameter space where the cylinder can undergo a jump after pure rolling motion. In previous works, it was assumed that slipping always precedes a jump, leading to the belief that slip is necessary. In contrast, our study challenges this prevailing notion by demonstrating the existence of situations where a jump can occur after pure rolling motion. We present a detailed theoretical description of the jump effect, investigating the dependence of the jump behavior on the initial conditions, the forces involved, and the parameter values. Through rigorous analysis, we determine the restricted region in the parameter space that allows for jumps to occur without slipping. Our findings contribute to the ongoing debate surrounding the jump effect in eccentric cylinder dynamics.
Acid Mine Drainage Management Plan and Utilization of Fly Ash as Neutralizing Agent (A Case Study of Post-Mining Pits in Palaran, East Kalimantan)
Authors: Rahayu Lestari Sri , Maming  , Diansari Pipi 
Published: December 2023

Abstract
With high levels of domestic production, consumption, and coal exports in East Kalimantan, the outcome will be directly proportionate. Disruption of abiotic, biotic, and cultural factors, such as the environmental impact on Kopi Palaran Street, where there are four abandoned post-mining pits surrounded by residential areas and filled with acid mine drainage. A new issue resulting from the effects of post-mining activities is residents using acid mine drainage from post-mining pits without treatment. The acidity level of the acid mine drainage that the people of Kopi Palaran Street used for daily sanitary reasons ranged from pH 2.8 to pH 3.3 and included relatively low-level Fe and Mn metal. According to the results of laboratory tests on the acid mine neutralisation process, adding 25 g of fly ash to 1000 mL of acid mine drainage can raise the pH of the acid mine water to 8.7 due to the process of alkaline minerals of the fly ash, such as CaO, dissolving acidic minerals. It can also increase the Fe metal content to 13.1 mg/L due to the precipitation of ferric hydroxide, while lowering the Mn metal content to 0.38 mg/L.
Analysis and Control of Land Use Deviations in the City of Parepare
Authors: Coutrier Cliff Joshua Martino , Munir Ahmad , Kurniaty  
Published: December 2023

Abstract
Population and economic growth in the city of Parepare have increased, which has a big impact on land conversion. The City of Parepare Government has published Regional Regulation Number 1 of 2021 regarding the Regional Spatial Plan (RSP) of the City of Parepare 2021–2041 in order to carry out spatial planning. Existing land cannot be used in accordance with RSP regulations after a change in land use. This study aims to find deviations from existing land use in 2022 against the RSP and how to control land use irregularities in Parepare City. The analysis used in this study utilizes a Geographic Information System (GIS) to obtain a map of existing land use in 2022 and an overlay analysis to find land use deviations, and interviews with officials related to land use control in Parepare City. The results of the analysis show that the land use that is following the function of the area in the spatial pattern of the RSP is 6280.23 ha or 69.57% and the land use that deviates from the function of the area in the spatial pattern of the RSP is 2753.28 ha or 30.48%. The issue with its implementation is that many people have exploited or built on the land despite not having the necessary permissions. In an effort to regulate land usage, socialization, monitoring, and the implementation of sanctions have been used; yet, in reality, some people continue to utilize property outside of the RSP.

Authors: Wang Zheng-Feng , Fu Lin , Yu En-Ping , Zhu Wei-Guang , Zeng Song-Jun , Cao Hong-Lin 
Published: December 2023

Abstract
Euryodendron excelsum is in a monotypic genus Euryodendron, endemic to China. It has intermediate morphisms in the Pentaphylacaceae or Theaceae families, which make it distinct. Due to anthropogenic disturbance, E. excelsum is currently found in very restricted and fragmented areas with extremely small populations. Although much research and effort has been applied towards its conservation, its long-term survival mechanisms and evolutionary history remain elusive, especially from a genomic aspect. Therefore, using a combination of long/short whole genome sequencing, RNA sequencing reads, and Hi-C data, we assembled and annotated a high-quality genome for E. excelsum. The genome assembly of E. excelsum comprised 1,059,895,887 bp with 99.66% anchored into 23 pseudo-chromosomes and a 99.0% BUSCO completeness. Comparative genomic analysis revealed the expansion of terpenoid and flavonoid secondary metabolite genes, and displayed a tandem and/or proximal duplication framework of these genes. E. excelsum also displayed genes associated with growth, development, and defence adaptation from whole genome duplication. Demographic analysis indicated that its fluctuations in population size and its recent population decline were related to cold climate changes. The E. excelsum genome assembly provides a highly valuable resource for evolutionary and ecological research in the future, aiding its conservation, management, and restoration.
White spot lesions after fixed appliance treatment—Can we expect spontaneous long-term (≥15 years) improvement?
Authors: Bock Niko Christian , von Bremen Julia , Klaus Katharina , Schulz-Weidner Nelly , Ganss Carolina , Ruf Sabine 
Published: December 2023

Summary

Objective
To investigate the extent to which post-orthodontic white spot lesions (WSLs) change in appearance over a period of ≥15 years and whether an association with caries data exists.

Subjects and Methods
Seventy-two patients treated with a Herbst-Multibracket appliance at age 14.0 ± 2.7 years for 20.1 ± 5.1 months who attended a recall 18.3 ± 2.9 years post-treatment. Post-treatment (T1) intraoral photographs were assessed by a panel of five dentists using a modified version of the WSL-Index by Gorelick. For affected incisors, photographs from before treatment (T0) and recall (T3) were evaluated. In addition, the WSL-Change Index by Pancherz and Muehlich was assessed for all adequately visible incisors considering T1, T2 (if available), and T3. Radiographic (T0, T1, and T2—if available) and clinical (T3) MFT data were used.

Results
37.5% of the patients exhibited WSLs on ≥ 1 incisor at T1; in total, 81 incisors (14.9%) were affected. At T3, 48% of the WSLs had improved. The modified WSL-Index decreased from 1.2 ± 0.4 to 0.8 ± 0.6 (P &lt; .001), with a score 0 in 28% of the previously affected incisors. When comparing T2 vs. T3, additional improvement after T2 occurred in 11% of the teeth. While no difference existed at T0, the MFT values at T1, T2, and T3 were higher (P ≤ .05) in patients with WSLs at T1 than in those without.

Limitations
The homogeneity of the subjects was limited and no patient-reported outcome was assessed.

Conclusions
Long-term, post-orthodontic WSLs showed spontaneous full recovery in 28% and improvement in 48% of the teeth. Patients affected with WSLs exhibited higher post-treatment MFT values.
Digest: Islands promote population differentiation in dispersive swallows
Authors: Estandía Andrea , Merino Recalde Nilo 
Published: December 2023

Abstract
How can highly dispersive species give rise to genetically distinct populations? This seemingly paradoxical pattern is common among insular birds, but not in those with continental distributions. Broyles and Myers sequence the genomes of almost 150 individuals from the island-dwelling Pacific swallow (Hirundo tahitica) and its continental counterpart, the welcome swallow (H. neoxena). They find strong population structure only among island populations and attribute this to a behavioral reduction in dispersal propensity following island colonization. However, wing shape remains consistent across populations, suggesting it might not accurately reflect dispersal propensity in this group. This study illustrates the interplay between dispersal, isolation, and divergence, offering insights into how geographic factors affect speciation and population differentiation on islands.

Published: December 2023

Abstract
The purpose of this study is to examine intervention processes including session completion and content of the ADS Plus program. Interventionists completed an investigator-developed delivery assessment form following completion of each ADS Plus session with participating caregivers. Additionally, information on care challenges addressed and strategies offered in the form of an “ADS Plus prescription were documented. A total of 102 caregivers took part in ADS Plus. There were 954 sessions conducted, an average of 9.4 sessions per caregiver (Range 0-22). The majority of sessions were completed face-to-face (56.8%), or by telephone (40.7%). The average time spent preparing for each session by staff was 15.5 minutes (range 0 -65). Top care challenges selected by caregivers to address in ADS were: (1) Taking care of self (n=34 caregivers), (2) Meaningful activities for the person living with dementia (n=17), and (3) Agitated behaviors (n=13). Most sessions included validation and support of caregivers (91.8%) and information on caregiver self-care (85.5%). Education (49.0%) and skill enhancement for challenge areas (50.1%) were provided in about half of the sessions. Only about a quarter of sessions, (23.9%) included provision of referrals and linkages. At follow-up caregivers reported that the care challenges they sought to address in ADS Plus had gotten better (54.4%) or was eliminated (26.3%). Caregivers of persons living with dementia who attend an ADS can be aided by the addition of the ADS Plus program to address targeted caregiving needs.
THE CANNABIS AND OLDER PERSONS STUDY: WHAT WE HAVE LEARNED
Authors: Kaskie Brian 
Published: December 2023

Abstract
The Cannabis and Older Persons Study has examined the increasing use of cannabis among Americans over 60 years old since 2016 reflecting a variety of disciplinary perspectives and methodological approaches. The project team has published a dozen peer reviewed manuscripts and has secured competitive funding swards in California, Colorado, Illinois and Iowa. In this symposium, results from multiple COPS surveys collected from older adults are reviewed with three goals in mind. The first is to demonstrate how older cannabis users are not comparable to younger cannabis users in terms of motives and self-reported outcomes of use. The second is to distinguish therapeutic from recreational cannabis use among older persons by examining survey answers provided by persons with arthritis, cancer, caregivers of persons with Alzheimer’s disease, multiple sclerosis and terminal illnesses. The third goal is to differentiate life-time from naïve cannabis users and consider how cannabis may serve as an opioid avoidance or harm reduction strategy. Discussion considers the critical role policy makers, program administrators and clinicians assume in facilitating or hindering cannabis use, and directions for future research.
