Correction to the Euler Lagrange Multirotor Model with Euler Angles Generalized Coordinates
Authors: Martini Simone , Valavanis Kimon P. , Stefanovic Margareta , Rutherford Matthew J. , Rizzo Alessandro 
Published: January 2024

AbstractThis technical note proves analytically how the exact equivalence of the Newton-Euler and Euler-Lagrange modeling formulations as applied to multirotor UAVs is achieved. This is done by deriving a correct Euler-Lagrange multirotor attitude dynamics model. A review of the published literature reveals that the commonly adopted Euler-Lagrange multirotor dynamics model is equivalent to the Newton-Euler model only when it comes to the position dynamics, but not in the attitude dynamics. Step-by-step derivations and calculations are provided to show how modeling equivalence to the Newton-Euler formulation is proven. The modeling equivalence is then verified by obtaining identical results in numerical simulation studies. Simulation results also illustrate that when using the correct model for feedback linearization, controller stability at high gains is improved.
On Real-time Cooperative Trajectory Planning of Aerial-ground Systems

Published: January 2024

AbstractCooperative trajectory planning of aerial-ground systems is a fundamental and challenging problem, which aims to leverage the aerial information to assist the ground tasks. Existing methods often suffer from suboptimal trajectories or computation burden. In this paper, we address cooperative trajectory planning of aerial-ground systems in which an unmanned ground vehicle (UGV) plans its local trajectory in real-time with the assistance of an unmanned aerial vehicle (UAV). Firstly, the UAV generates guidance trajectory using nonlinear model predictive control (NMPC), which considers the obstacle distribution density as a factor reflecting the coupling effect of multiple obstacles on the UGV, thereby avoiding local minima problem and improving the feasibility of the planned trajectory. Secondly, a null-space-based behavioral control (NSBC) framework is employed to merge the guidance trajectory into the UGV’s own planned one as a task. Finally, an event triggering task supervisor is developed for the UGV to decide the priorities of all tasks, which reduces the switching frequency of task priorities brought by traditional rule-based task supervisors. Both simulation and experiment results show that the proposed approach has superior trajectory planning performance in terms of trajectory error, on-line computation time and the success rate of task execution.
Spatiotemporal changes in hurricane-force wind risk assessment in the Yucatan Peninsula, Mexico
Authors: Romero David , León-Cruz José Francisco 
Published: January 2024

AbstractTropical cyclones are one of the most dangerous natural phenomena. These extreme events involve various hazards, such as strong winds, severe precipitation, storm surge, flooding, and landslides. In Mexico, tropical cyclones are the most frequent natural threats and have a high cost to affected populations. This research aimed to characterise the spatial and temporal changes in risk associated with hurricane winds on the Yucatan Peninsula. This effort included a comprehensive analysis of three integral risk components (hazard, vulnerability, and exposure) for three distinct time intervals (1950–2000, 1950–2010, and 1950–2020). This analytical process was executed utilising a fine-resolution hexagonal grid. Hazard was estimated by calculating the probabilities of occurrence of winds related to various hurricane categories after estimating wind fields from the International Best Track Archive for Climate Stewardship (IBTrACS) data with a parametric model. Vulnerability was approximated by constructing indicators with sociodemographic data from the National Population and Housing Census issued by Mexico’s National Institute of Statistics and Geography. With these indicators, a factor analysis was performed, and a weighted index was constructed. Finally, exposure was estimated from population density. Each of these indices was aggregated at the hexagonal level, allowing the calculation of the risk associated with hurricane-force wind. The results showed high-risk levels associated with high-hazard levels, e.g. in coastal areas such as the Riviera Maya. Similarly, high-risk levels are related to high marginalisation, i.e. vulnerability, in the northeastern zone of the Yucatan Peninsula. The increased frequency of tropical cyclones combined with high population densities has recently led to higher risk levels in this region of Mexico.
Gender inequalities in social club participation in Europe: the role of women’s empowerment at the country level
Authors: Solé-Auró Aïda , Arpino Bruno 
Published: January 2024

AbstractThis study examines gender inequalities in the degree of engagement in social clubs of older people and how women’s participation relates to their empowerment at the country level. Combined individual-level data from the Survey of Health, Ageing and Retirement in Europe (SHARE) and country-level data from the Women’s Political Empowerment Index (WPEI) are used in analyzing 41,185 non-working individuals aged 65–84 across 19 countries. Multilevel regression analyses are conducted to address these aims. We detect notable between-country variations in levels of participation. Substantial differences in the WPEI reflect marked contextual cross-country differences in gender equality. In roughly half of the 19 countries, no gender differences in social club participation are detected; however, women are more likely to participate in social clubs in the more gender-egalitarian countries of France, Denmark, Luxembourg and the Netherlands, whereas in three countries – Italy, Czech Republic and Croatia – more men than women participate in social clubs. Cross-country gender differences in social club participation point to the importance of cultural factors in influencing opportunities for active ageing.

Abstract
Introduction
Lipids are key compounds in the study of metabolism and are increasingly studied in biology projects. It is a very broad family that encompasses many compounds, and the name of the same compound may vary depending on the community where they are studied.

Objectives
In addition, their structures are varied and complex, which complicates their analysis. Indeed, the structural resolution does not always allow a complete level of annotation so the actual compound analysed will vary from study to study and should be clearly stated. For all these reasons the identification and naming of lipids is complicated and very variable from one study to another, it needs to be harmonized.

Methods & Results
In this position paper we will present and discuss the different way to name lipids (with chemoinformatic and semantic identifiers) and their importance to share lipidomic results.

Conclusion
Homogenising this identification and adopting the same rules is essential to be able to share data within the community and to map data on functional networks.
The form-affordance-function (FAF) triangle of design
Authors: Sareh Pooya , Loudon Gareth 
Published: January 2024

AbstractFor centuries, the relationship between form and function has been a point of debate in the communities of architecture and design, leading to the development of various theories which have attempted to establish a tangible relationship between these two entities. Besides, the concept of affordance, adopted from Gibson’s ecological psychology theory, has appeared as a widely-used concept in design practice and research. Nevertheless, while it is generally accepted that these concepts have close dependencies and interactions, it appears that there is no explicit theoretical framework that relates three of the most fundamental concepts of design, namely form, function, and affordance. This paper aims to analyze the concept of affordance in the context of industrial design, where we attempt to develop insights into the role of affordances in relation to form and function. To this end, we define the form-affordance-function (FAF) triangle of design as a major contributor to the establishment of a partial product design specification (PDS) in the design process. We present several examples to investigate the position of affordances in competition with other design considerations such as engineering performance, ergonomics, and aesthetics. The insights into these relationships could have potential implications for designers in making informed early-stage design decisions.

AbstractAlthough the functions of programmed death-1 (PD-1) on αβ T cells have been extensively reported, a role for PD-1 in regulating γδT cell function is only beginning to emerge. Here, we investigated the phenotypic and functional characteristics of PD-1-expressing γδT cells, and the molecular mechanism was also explored in the Plasmodium yoelii nigeriensis (P. yoelii NSM)-infected mice. Flow cytometry and single-cell RNA sequencing (scRNA-seq) were performed. An inverse agonist of RORα, SR3335, was used to investigate the role of RORα in regulating PD-1+ γδT cells. The results indicated that γδT cells continuously upregulated PD-1 expression during the infection period. Higher levels of CD94, IL-10, CX3CR1, and CD107a; and lower levels of CD25, CD69, and CD127 were found in PD-1+ γδT cells from infected mice than in PD-1− γδT cells. Furthermore, GO enrichment analysis revealed that the marker genes in PD-1+ γδT cells were involved in autophagy and processes utilizing autophagic mechanisms. ScRNA-seq results showed that RORα was increased significantly in PD-1+ γδT cells. GSEA identified that RORα was mainly involved in the regulation of I-kappaB kinase/NF-κB signaling and the positive regulation of cytokine production. Consistent with this, PD-1-expressing γδT cells upregulated RORα following Plasmodium yoelii infection. Additionally, in vitro studies revealed that higher levels of p-p65 were found in PD-1+ γδT cells after treatment with a RORα selective synthetic inhibitor. Collectively, these data suggest that RORα-mediated attenuation of NF-κB signaling may be fundamental for PD-1-expressing γδT cells to modulate host immune responses in the spleen of Plasmodium yoelii nigeriensis–infected C57BL/6 mice, and it requires further investigation.

Abstract
Background
γ1-Adaptin is a subunit of adaptor protein complex-1 (AP-1), which regulates intracellular transport between the trans-Golgi network (TGN) and endosomes. Since expression levels of AP-1 subunits have been reported to be associated with cell proliferation and cancer malignancy, we investigated the relationships between the immunohistochemical expression of γ1-adaptin and both clinicopathological factors and relapse-free survival (RFS) in breast cancer tissue.

Materials and methods
SK-BR-3 cell line depleted of γ1-adaptin was used for cell proliferation, migration, and invasion assay. Intracellular localization of γ1-adaptin was examined with immunohistochemistry (IHC) using an antibody against γ1-adaptin, and with double immunohistofluorescence (IHF) microscopy using markers for the TGN and endosome. γ1-Adaptin intensities in IHC samples from 199 primary breast cancer patients were quantified and assessed in relation to clinicopathological factors and RFS.

Results
Cell growth, migration, and invasion of SK-BR-3 cells were significantly suppressed by the depletion of γ1-adaptin. Although the staining patterns in the cancer tissues varied among cases by IHC, double IHF demonstrated that γ1-adaptin was mainly localized in EEA1-positive endosomes, but not in the TGN. γ1-Adaptin intensity was significantly higher in the tumor regions than in non-tumor regions. It was also higher in patients with Ki-67 (high), ER (–), PgR (–), and HER2 (+). Among subtypes of breast cancer, γ1-adaptin intensity was higher in HER2 than in luminal A or luminal B. The results of the survival analysis indicated that high γ1-adaptin intensity was significantly associated with worse RFS, and this association was also observed in group with ER (+), PgR (+), HER2 (–), Ki-67 (high), or luminal B. In addition, the Cox proportional hazards model showed that high γ1-adaptin intensity was an independent prognostic factor.

Conclusion
These results suggest that the endosomal expression of γ1-adaptin is positively correlated with breast cancer malignancy and could be a novel prognostic marker.
Optimal trade execution in cryptocurrency markets
Authors: Bundi Nils , Wei Ching-Lin , Khashanah Khaldoun 
Published: January 2024

AbstractNovel technologies allow cryptocurrency exchanges to offer innovative services that set them apart from other exchanges. In this paper we study the distinct features of cryptocurrency fee schedules and the implications for optimal trade execution. We formulate an optimal execution strategy that minimizes the trading fees charged by the exchange. We further provide a proof for the existence of an optimal execution strategy for this type of fee schedule. The optimal strategy involves both market and limit orders on various price levels. The optimal order distribution scheme depends on the market conditions expressed in terms of the distribution of limit order execution probabilities and the exchange’s specific configuration of the fee schedule. Our results indicate that a strategy kernel with an exponentially decaying allocation of trade volume to price levels further away from the best price provides superior performance and potential reduction of trade execution cost of more than 60%. The robustness of these results is confirmed in an empirical study. To our knowledge, this is the first study of optimal trade execution that takes into consideration the full fee schedule of exchanges in general.

AbstractTomato leaf miner, Tuta absoluta (Lepidoptera: Gelechiidae), is a serious insect pest on tomato plants worldwide. Its larvae can cause up to 100% damage if not controlled. Furthermore, using of chemical pesticides is causing serious threat to environment and human health. The effect of two photosensitizers; magnesium and copper chlorophyllin (Mg-Chl and Cu-Chl) alone and two nanomaterials (GO and Ag) over their photosensitizers (Mg-Chl /Go, Mg-Chl /Ag, Cu-Chl/ Go, and Cu-Chl /Ag) on T. absoluta in tomato field at two seasons were studied. The tested concentrations of photosensitizer and nanocomposites were 10−3 (100 ml/L), 10−4 (10 ml/L) and 10–5 (1 ml/L). The effect of photosensitizer and nanocomposites on reduction % of Tuta absoluta, tomato plants growth, yield, and quality were studied. The number of tunnels was recorded, the reduction percentages for each treatment were calculated compared to control before and after 1, 5, and 7 days of spraying. Results showed that the reduction in the number of tunnels after one day of spraying with photosensitizers (Mg-Chl and Cu-Chl) at the highest concentration (10−3) was 72.79 and 70.52% in the 1st season and 77.95 and 60.08% in the 2nd season. The reduction percentage increased gradually with the number of days after spraying and reached 100% after seven days in both seasons. The reduction percentage reached 100% in plants treated with all nanomaterial concentrations after five days of spraying in the 1st season and after one day of spraying in the second season. Photosensitizer and nanocomposites treatments at all concentrations positively affected all vegetative growth parameters of tomato plants compared with insecticides and control. The highest concentration of all treatments increased yield and enhanced the storability of tomato fruits. The yield after treatment with Mg-Chl was 28.67 tons/fed, which was more than the yield of those treated with Cu-Chl (24.8 tons/fed). Loading nano silver (Ag) over Mg-Chl achieved tomato yield (35.18 tons/fed) compared with the loading of nano graphene oxide (Go) (32.95 tons/fed). Therefore, treatment with these materials can be recommended in the IPM program to control T. absoluta in tomato fields.
Supramolecular chirality in self-assembly of zinc protobacteriochlorophyll-d analogs possessing enantiomeric esterifying groups
Authors: Yasui Mizuki , Tamiaki Hitoshi 
Published: January 2024

AbstractZinc 3-hydroxymethyl-pyroprotopheophorbides-a esterified with a chiral secondary alcohol at the 17-propionate residue were prepared as bacteriochlorophyll-d analogs. The synthetic zinc 31-hydroxy-131-oxo-porphyrins self-aggregated in an aqueous Triton X-100 micellar solution to give red-shifted and broadened Soret and Qy absorption bands in comparison with their monomeric bands. The intense, exciton-coupled circular dichroism spectra of their self-aggregates were dependent on the chirality of the esterifying groups. The observation indicated that the self-aggregates based on the J-type stacking of the porphyrin cores were sensitive to the peripheral 17-propionate residues. The supramolecular structures of the present J-aggregates as models of bacteriochlorophyll aggregates in natural chlorosomes were remotely regulated by the esterifying groups.

Decomposing Firm Performance in Emerging Markets: The Difference Between Growth and Profit
Authors: Zhou Nan , Park Seung Ho 
Published: January 2024

AbstractThis study adopts the resource-based view (RBV) to explain the difference in firm profit and growth determinants. We argue that profit is driven more by valuable, rare, inimitable, and non-substitutable (VRIN) resources, and growth is driven more by versatile resources. Since some versatile resources, such as cash, are less firm-specific, the firm effect is more critical in determining profit than growth. We also expect that emerging market firms are more capable of utilizing versatile resources than developed market firms, and developed market firms are more capable of utilizing VRIN resources than emerging market firms. As a result, the determinants of firm performance also differ between emerging and developed markets. The study employs multilevel mixed models to decompose firm performance in US, Chinese, and global samples. The findings confirm that the firm effect is more important in influencing profit than growth, persisting across all three samples. The firm effect is also more important in influencing performance in developed countries than in emerging markets.
PLATO ON CORRECTING PHILOSOPHICAL CORRUPTION
Authors: Heckel Marta 
Published: January 2024

AbstractPlato's Republic VII suggests that if we ask someone to philosophize when they are too young, they can become corrupted (537e–539d). Republic VII also suggests that to avoid this corruption, we must not expose youth to argument (539a–b). This is not a reasonable option outside of Kallipolis, so a question arises: does Plato describe how to correct corruption if we do not manage to prevent it? This paper shows that a parallel between this passage from Republic VII and a passage from Laws X suggests that he does. Laws X describes an impious man who is corrupted in the same way as the youth exposed to philosophy prematurely in Republic VII. While we leave the youth to his corruption in Republic, the impious man is helped to overcome his corruption in Laws with a refutation followed by a myth (also called a charm). This paper analyses these steps in terms of Plato's psychology, showing that both corruption and correction require a destabilization of the soul, which in these passages is brought about through refutation. This destabilization allows for a reconfiguration, which, with something that can restabilize the soul (for example with myth), can be a reconfiguration for the better.
Human–crocodile interactions in the western Solomon Islands: the importance of local data for reducing attacks on people
Authors: Aswani Shankar , Matanzima Joshua 
Published: January 2024

AbstractInteractions between people and the saltwater crocodile Crocodylus porosus frequently occur on islands and in coastal regions. Saltwater crocodiles impact people's lives and livelihoods by attacking them, resulting in minor or serious injuries, and by interfering in people's foraging activities. Retaliation may include killing the crocodiles involved. To reduce such human–crocodile interactions, data about the occurrence of incidents are required. We present data on encounters with crocodiles and attacks on people in the Roviana Lagoon, Solomon Islands. Data includes time of incident, gender, age and activity of the victim, water conditions and what happened to the crocodile after the incident. We used a questionnaire to capture the details of incidents that occurred during 2000–2020 in the villages of Dunde, Baraulu, Nusa Hope and Kozou. Most incidents were in the evening, mostly involving women, and most victims were aged 20–39 years or ≥ 60 years. In all cases people were attacked while gleaning for shellfish in the mangroves. Attacks occurred irrespective of whether the water was clear or murky, and in all cases the crocodiles were not killed. Such site-specific data will facilitate the formulation of strategies for reducing negative interactions between people and crocodiles in this particular location. Although the saltwater crocodile is categorized as Least Concern on the IUCN Red List, research such as this provides data that can be used for promoting coexistence with and conservation of this species.
Evil and responsibility in the Quran
Authors: Abdalla Bakinaz 
Published: January 2024

AbstractThe Quran contains numerous references to evil and some of these indicate that the responsibility of some instances of evil, which I call self-inflicted evil, lies with human beings rather than God. This idea of evil leads to an exploration of two interconnected issues in philosophical and theological discussions, moral responsibility and desert, along with the related tension between freedom of action and divine determinism. The article delves into this tension as it appears from the Quran and prevailing standpoints in Islamic theology. I propose that the tension between freedom of action and divine determinism resists a satisfactory reconciliation, which ultimately affects the plausibility of the idea of evil as self-inflicted. I further propose that embracing the contradictions arising from verses expressing freedom and responsibility, on the one hand, and those indicating divine determinism, on the other, could be a viable approach for the theologian.
