Taphonomic analysis of a Caribbean subfossil herpetofaunal bone assemblage (Marie Galante Island, Lesser Antilles)
Authors: SAYAH Morgane , LENOBLE Arnaud , BOCHATON Corentin 
Published: July 2023

Taphonomic analyses are of primary importance to understand the accumulation processes of fossil vertebrate bone assemblages. These approaches are fundamental in archaeological contexts in which the role of humans in the formation of an accumulation must be investigated in detail. However, taphonomic works have so far focused on temperate regions and mammals and few studies extensively deal with other vertebrates, especially the herpetofauna, and tropical areas. This results in an important gap in the scientific literature, which has a strong impact on the paleoecological and zooarchaeological research in the areas where squamates and amphibians are well-represented. In this paper, we present a detailed taphonomic study of a large herpetofaunal assemblage of nearly 11 000 bones collected in the Abri Cadet 3, on Marie Galante Island, and dated from the beginning of the Holocene to the Amerindian period. Obtained results don’t support the role of humans in the constitution of the assemblage despite the occurrence of clear archaeological layers in the site. The most-likely culprit for the creation of the bone assemblage is a small nocturnal raptor (i.e., Athene cunicularia guadeloupensis (Ridgway, 1874) or Tyto insularis (Pelzeln, 1872)). We also conduct a comparison with the other available deposits from Marie Galante, highlighting the diversity of accumulation processes in the different nearby cave sites but also the lack of detailed taphonomic studies which would be needed to explain this diversity.

Authors: Mondal Indrajit , Zoabi Adan , Haick Hossam 
Published: February 2025

AbstractBreath analysis offers a non‐invasive approach to modern diagnostics by capturing volatile organic compounds (VOCs) in exhaled breath. However, current breath analysis technologies face challenges like humidity sensitivity, high costs, and biodegradable solutions, limiting their scalability and environmental sustainability. This study presents a paper‐based, biodegradable, humidity‐insensitive electronic nose (e‐nose) sensor array integrated into a face mask for real‐time breath analysis. The sensors, coated with hydrophobic polymer coating, ensure robust insensitivity to humidity, enabling reliable detection of VOCs even in high‐moisture environments. The mask‐integrated e‐nose facilitates real‐time breath monitoring for applications such as alcohol consumption tracking and respiratory health assessment. For the latter, Tuberculosis (TB) detection is selected as a representative use case, achieving 89% accuracy in disease diagnosis and recovery monitoring using a pre‐trained deep‐learning model. The fully‐biodegradable paper‐based sensor naturally degrades in soil within months, underscoring its eco‐friendly design and suitability for disposable health monitoring. This work introduces a sustainable, user‐friendly approach to breath analysis with potential applications in non‐invasive disease detection and personalized healthcare monitoring.

ABSTRACTThe effects of feeding on insect larvae treated with pesticide on the biological and biochemical characteristics of Arma chinensis were investigated. In the F0 generation, the developmental duration and preoviposition period were shortened, the average number of eggs laid was reduced, and the net reproductive rate and mean generation time were significantly lower in the treatment group compared to those in the control group. The average number of eggs laid by the F1 generation of A. chinensis was lower in the treatment group. The intrinsic rates of increase, finite rates of increase and net reproductive rates were significantly lower in the F1 generation in the treatment group than those in the control group. The activities of CarE and GST were significantly induced, while the activity of AChE was inhibited in the A. chinensis in the treatment group. The activities of trypsin and THL were significantly induced in the treatment group, while the activity of LPS was not significantly changed. At the population level, Enterococcaceae were cultured only from the intestines of the A. chinensis in the treatment group. At the genus level, in addition to Serratia, Yokenella and Klebsiella, which were consistent with the control group, the genus Enterococcus was also cultured in the treatment group. When controlling P. rapae in the field, pesticides should be reasonably selected, and an appropriate time should be chosen for the release of A. chinensis to reduce the impact on natural enemies and to achieve synergistic chemical and biological control.
Robust optimal distance‐based formation control of uncertain nonlinear agents over directed topologies
Authors: Babazadeh Reza , Selmic Rastko R. 
Published: February 2025

AbstractThis paper studies a formation control problem with distance constraints for nonlinear agents with uncertainties. Controlling an edge is assigned to only one of its incident agents. Directed graph theory is used to model the desired formation topology. The method is distributed, applicable to uncertain nonlinear agents, and is based on robust‐optimal control. The proposed control scheme is based on integral sliding mode control (ISMC) combined with the state‐dependent Riccati equation (SDRE) method. The method minimizes a weighted cost function that includes the formation and control input costs for a given mission while compensating for the effect of uncertainties. A rigorous Lyapunov stability analysis proved the local asymptotic convergence of the agents to the desired distances. We use the concept of mathematical induction to show that the formation of all agents is stable. Detailed simulation results are included to verify the proposed control scheme.
Analysis, Design, and Hardware Implementation of a Novel Isolated DC‐DC Converter for Medium‐Power Electric Vehicle Battery Charging

Published: February 2025

ABSTRACTThe rapid depletion of fossil fuels in recent decades has drawn global attention to the need for renewable energy sources. In addition, electric vehicles (EVs) are gaining importance as they are the cleanest form of transportation, contributing to the reduction of pollution and global warming. EV batteries require DC energy to charge. Renewable energy‐powered charging is an environmentally friendly and increasingly feasible method for meeting energy needs while minimizing the negative environmental effects of transportation and electricity production. It is anticipated that the use of renewable energy technology will significantly impact global energy and transportation systems in the future due to its ongoing improvements and decreasing prices. This research introduces a novel approach to developing and implementing an isolated DC‐DC converter with a single‐stage power conversion. To synthesize the proposed isolated DC‐DC converter, a MOSFET H‐bridge, a high‐frequency transformer, and a bridgeless Luo converter were combined, considering the input‐parallel‐output‐parallel (IPOP) configuration. Bridgeless Luo converters significantly reduce the conductive and switching losses of the semiconductor by replacing the full‐bridge diode rectifier. This work details the operating modes of the proposed isolated DC‐DC converter, along with the corresponding dynamic equations. Further, the average large signal and steady‐state models are detailed to obtain the design of storage elements for the desired specifications. The system under consideration is simulated, and waveforms depicting the voltages and currents of various components are provided. A prototype with a 100‐W power output is created to test the performance of the proposed converter to charge a lithium‐ion battery at a voltage of 48 V. The loss components in the converter are analyzed, and the energy buildup in the battery during the hardware implementation is also presented. Silicon carbide (SiC) MOSFETs and diodes are employed in the prototype to enable high switching frequency operation leading to reduced size and weight of the components. The proposed converter is seen to be a novel isolated DC‐DC converter with low output ripples and lower losses, suitable for medium‐power EV battery charging.
Pre‐ and Post‐Copulatory Sexual Traits Influence Male Fitness Across a Mosaic Hybrid Zone

Published: February 2025

ABSTRACTPrimary and secondary male sexual traits can influence the interspecific interactions of hybridizing populations, yielding fitness consequences and either promoting or restricting gene flow. In this study, we evaluated the relative male fitness of two species of hybridizing tidal marsh endemics: saltmarsh (Ammospiza caudacutus) and Nelson's sparrows (A. nelsoni) and assessed the effects of male condition and competitive ability on resulting patterns of paternity and gene flow. We compared reproductive success (number of offspring sired) among saltmarsh, Nelson's, and hybrid sparrow males (n = 125) and modeled male fitness in relation to measured pre‐copulatory (body size, fat scores, and muscle scores) and post‐copulatory (cloacal protuberance (CP) volume and sperm length) male sexual traits across two sites within the center of the hybrid zone. We found saltmarsh sparrows had higher levels of skew in fertilization success than Nelson's and greater reproductive output than both Nelson's and hybrids, suggesting interspecific competition may occur. Body size was the best predictor of reproductive success, independent of male genotypes, providing evidence for a role of pre‐copulatory sexual selection. We also found evidence of post‐copulatory sexual selection and sperm competition contributing to patterns of hybridization, with CP volume and sperm length increasing with number of offspring sired. Differential mean fitness by species may influence patterns of hybridization and has the potential to drive asymmetrical introgression; however, the drivers of male fitness differed between species and sites, suggesting the level of sexual selection and resulting patterns of gene flow are context dependent and not stable across a small sptatial scale within the center of this mosaic hybrid zone. Overall, few interspecific offspring and nearly equal backcrossing in both parental species within the center of the hybrid zone suggest mechanisms such as reinforcement exist to limit hybridization and minimize asymmetric introgression.
Copulatory Mechanics Reveals a Self‐Bracing Mechanism via a Femoral Apophysis in Funnel Weavers (Araneae, Agelenidae)

Published: February 2025

ABSTRACTSpiders utilize an indirect method of sperm transfer via specialized male palpal structures. In entelegyne spiders, these structures exhibit a remarkable complexity, comprising various sclerites that interlock with the female genitalia to provide stability and facilitate sperm transfer. Among the four primary coupling mechanisms recognized in entelegyne spiders, one, termed self‐bracing, involves interactions between structures stabilizing the expanded copulatory organ during mating. Such interactions can involve elements that are not part of the copulatory organ. The retrolateral tibial apophysis (RTA), a characteristic of the largest group of spiders (RTA clade), is the most prominent structure for this purpose. However, recent research has demonstrated that in spiders that have lost the RTA, other parts of the palp, specifically femoral apophyses, can be involved in self‐bracing. The presence of a femoral palpal fapophysis is uncommon in spiders, and only a few taxa possess apophyses on multiple palpal articles, i.e., tibia and femur, the interaction and evolution of which remain to be elucidated. This study investigated the function and interaction of apophyses on different palpal structures for the first time using the funnel weaver Anatextrix monstrabilis (Agelenidae). We specifically examined the hypothesis that the various prominent femoral apophyses are involved in self‐bracing despite the presence of an RTA. Micro‐computed tomography data of a cryofixed mating pair revealed that at least one of these apophyses functions in self‐bracing by fitting into the groove of the embolic base, representing the second documented case of this unique self‐bracing mechanism in entelegyne spiders. Furthermore, scanning electron microscopy revealed previously undocumented features in the female genitalia of Anatextrix, including an epigynal fovea, an anterior hood, and well‐developed epigynal lateral margins, which potentially play a role in interlocking with male palpal sclerites during copulation. In contrast to ghost spiders (Anyphaenidae), the only other known group of entelegyne spiders exhibiting self‐bracing with femoral apophyses, Anatextrix species demonstrate notable differences with regard to the size and shape of these apophyses. Thus, our study indicates that male palpal femoral structures, which do not contact female genitalia during genital coupling, can be subject to strong selection pressures similar to somatic structures that function beyond basic sperm transfer.

Published: February 2025

ABSTRACTFACTS devices, functioning as controlled series voltage and parallel current source converters in transmission lines, can enhance network flexibility. The currents and voltages are regarded as unknown variables in the impedance estimation equations of the distance relay during fault occurrence. Typically, addressing the issues of protection systems for lines integrated with FACTS devices necessitates the development of a novel protection algorithm informed by the current line topology. A novel approach to address this difficulty involves employing an algorithm to estimate the injected current and voltage parameters of the series and parallel converters in FACTS devices. This research presents an estimation scheme utilizing artificial neural networks to determine the magnitude and phase angle of voltage and current in voltage source converters of the UIPC during short‐circuit faults in transmission lines. The proposed approach has been designed for use across diverse locations, phases, resistances, and fault durations on both sides of the UIPC. The voltage and current magnitudes and angles for all three bus sequences on one side of the line, along with the voltage magnitude and angle of the equivalent circuit of the series converters and the current magnitude and angle of the shunt converter, have been recorded. The primary aim of this work is to introduce an estimation model derived from the measurement data of the bus and the UIPC converters. Ultimately, by employing the estimated phasors, the impedance and, consequently, the distance from the fault location to the relay may be accurately determined, eliminating the necessity to alter the configuration and formulation of the distance relay. The approach has undergone testing and evaluation for various short circuit scenarios on both sides of the UIPC under diverse conditions. The successful outcomes demonstrated in the simulation section indicate that the proposed technique effectively estimates the UIPC phasor during a fault.

Published: February 2025

ABSTRACTHybrid energy storage systems (HESS) comprising supercapacitors and batteries in photovoltaic (PV) applications ensure overall system performance by compensating for their mutual drawbacks. However, the reliability of the PV‐based HESS against frequent load variation and irregular solar irradiance demands a robust power management scheme (PMS) and associated control strategies. This paper presents an enhanced DC voltage stabilization control strategy for robust PMS for the PV‐based HESS. The proposed control approach ensures stable DC link voltage regulation, improving the overall efficiency and thus reliability of the overall system. A comprehensive analysis of the system dynamics and control objectives is conducted under different operating conditions, leading to the development of a combined tilt‐integral (TI) and fractional proportional‐integral (FOPI)‐based controller. The controller parameters are estimated using the particle swarm optimization (PSO) technique and a gradient‐free Nelder–Mead simplex search (NMSS) algorithm for optimizing the time‐domain parameters. Thereafter, the dynamic performance of the presented PMS is investigated through extensive experimentation analyzed in terms of various parameters. The investigation suggests that the proposed control scheme outperforms the conventional control approach by a significant margin of 60.81% and 40.42% in steady‐state error and peak overshoot, respectively. Also, the state of charge (SOC) consumption of the battery is reduced by 8.46%, thus increasing the overall lifespan of the energy storage system. Therefore, the proposed control strategy offers a viable solution for ensuring stable and efficient operation of PV‐based energy storage systems, contributing to the advancement of renewable energy integration and grid resilience.
Beyond Money: Incentive Effects of Tokenized Ownership on User Contribution in DAOs

Published: February 2025

ABSTRACTBlockchain technologies have catalyzed the rise of decentralized autonomous organizations (DAOs), which operate in an incentive network fueled by crypto tokens. In essence, these tokens are imbued with either payment rights (i.e., transactional tokens) or ownership rights (i.e., governance tokens). The decentralized organizational paradigm dismantles the traditional management structure and bring new research opportunities to Operations Management (OM). While the performance of DAOs has been largely examined in current OM literature, the effectiveness of their internal incentive mechanisms—specifically the one that uses ownership as rewards to promote user contributions—remains unclear. Focusing on DAO‐enabled virtual communities, we seek to examine whether decentralized ownership provides stronger incentives for user behaviors, such as creation and curation, in comparison to traditional monetary rewards through the lens of psychological ownership theory. We obtained data from Steemit that captures the reward, creation, curation and transaction behaviors of 98,000 users from May 2017 to April 2019. By leveraging the “power‐up” action as a shock that increases user ownership shares, we established a quasi‐experimental setting. Employing the PSM‐DID model, we found that the use of governance tokens is associated with enhanced creation and curation efforts but declined creation novelty, compared to the use of transactional tokens. Our additional analyses further reveal that the incentive effects of governance tokens diminish over time. However, upon the recurrence of the intended choice, these effects become reinforced. Notably, we find that governance token ownership is more strongly associated with curation efforts for users with weaker social ties. Conversely, for users with high reputation scores, their content creation behaviors are less strongly associated with governance token ownership. This study contributes to the burgeoning discourse on blockchain and cryptocurrency from an operational perspective, providing valuable insights for the design of incentive mechanisms in DAOs and advancing our understanding of operational efficiencies and stakeholder engagement in decentralized structures within Operations Management.
