Published: January 2025

Abstract
The study highlights the critical mechanistic data supporting the ecological restoration advantages of biochar (BC) and its role in sustainable environmental management. Recognizing the substantial influence of specific feedstock sources and pyrolysis parameters on BC efficacy, this research aims to address these gaps through an extensive investigation into the potential benefits of BC application in ecological restoration. The methodology involves a systematic exploration of effects of BC from latest literature on various aspects of agricultural sustainability, including its ability to support crop growth, improve nutrient bioavailability, facilitate co-composting, enhance consumption efficiency, and contribute to water quality restoration. The main results of the study reveal that BC usage results in a net negative carbon (C) footprint, mitigates heavy metal pollution, and enhances soil and ecosystem health. In bioenergy production, BC serves as a versatile resource for generating renewable energy, reducing waste, and facilitating C sequestration. Advanced BC techniques, such as tailored pyrolysis processes and activation methods, further enhance its effectiveness in ecosystem restoration and sustainable resource management. Furthermore, the research identifies deficiencies in current literature and proposes future research directions to advance understanding of BC application. Overall, the study underscores the importance of considering feedstock and pyrolysis variables in BC research and highlights the potential of BC to contribute to ecological sustainability. However, concerns regarding potential health implications for humans in agricultural contexts warrant further investigation and risk assessment to ensure safe and sustainable BC application.

Open-atmosphere spinning of carbon nanotube fibers sans hydrogen flow by floating catalyst chemical vapor deposition: an insight into the mechanism
Authors: Alexander Rajath , Kaushal Amit , Singh Jaspreet , Dasgupta Kinshuk 
Published: January 2025

Abstract
This study introduces a novel method for synthesizing carbon nanotube (CNT) fibers using floating catalyst chemical vapor deposition (FC-CVD) in an open-atmosphere without the need for hydrogen as a carrier gas. Traditional FC-CVD techniques depend on hydrogen gas and require a harvest box with inert gas purging, which restricts scalability. Our approach utilizes nitrogen gas as the sole carrier, allowing for CNT fiber production without a harvest box. To understand the spinning process mechanism in an open-atmosphere, we conducted thermodynamic and computational fluid dynamics (CFD) analyses. Methanol was selected as the carbon source based on thermodynamic calculations, which revealed that at high temperatures, methanol forms CO and H2 as thermodynamically stable species instead of carbon (C), thereby preventing soot formation. Moreover, methanol undergoes catalytic cracking exclusively in the presence of catalysts, further preventing soot formation. This approach allows operation at high partial pressure, even above the upper explosive limit (UEL), effectively preventing combustion. A 600 mm cooling zone was incorporated into the reactor to lower the outlet gas temperature below methanol's auto-ignition point, mitigating combustion risks. CFD calculations were employed to determine the necessary cooling zone length. Additionally, we developed a predictive model using the XGBoost machine learning method to efficiently map the parameter space for CNT fiber spinning, achieving an accuracy of 95.24%. The resulting CNT fibers demonstrate high electrical conductivity (240 ± 24 S/cm) and a low ID/IG ratio, indicating a high degree of crystallinity.
A comprehensive overview of load balancing methods in software-defined networks
Authors: Farahi Rasoul 
Published: January 2025

Abstract
In prospective advancements, it is anticipated that software-defined networking (SDN) will establish itself as the principal framework for the implementation of heterogeneous networks. Unlike traditional networking paradigms, SDN differentiates the control and data planes, thereby enabling enhanced routing and management of traffic across various domains. The controllers located within the control plane are responsible for programming the forwarding devices situated in the data plane, whereas the highest layer, referred to as the application plane, enforces regulatory policies and coordinates network programming. Interfacing mechanisms are utilized across the different layers of SDN to ensure effective communication. Nonetheless, SDN faces challenges related to traffic distribution, such as load imbalance, which could negatively affect overall network performance. In response, developers have formulated a range of SDN load-balancing solutions intended to improve the efficiency of SDN. Furthermore, owing to the swift advancements in the domain of artificial intelligence (AI), researchers are investigating the viability of incorporating AI methodologies into SDN to optimize resource utilization and enhance overall performance. This survey is organized as follows: First, it provides an analysis of the SDN architecture and investigates the load balancing challenges present within SDN. Second, it classifies AI-driven load balancing strategies and critically assesses these mechanisms from multiple perspectives, including the algorithms/techniques utilized, the particular issues addressed, and their corresponding advantages and disadvantages. Third, it consolidates the metrics used to evaluate the effectiveness of these techniques. Finally, it identifies the emerging trends and challenges associated with AI-enhanced load balancing for future research endeavors.

Published: January 2025

Abstract
Passive microwave measurements of Arctic sea ice have been conducted over the last 50 years from space and during airborne, ship- and ground-based measurement campaigns. The different radiometric signatures of distinct surface types have led to satellite retrievals of, e.g., sea-ice concentration. In contrast, ground-based upward-viewing radiometers measure radiation emitted from the atmosphere and are used to retrieve atmospheric variables. Here, we present results from a ship-based radiometer setup with a mirror construction, which allows us to switch between atmospheric and surface measurements flexibly. This way, in summer 2022, surface observations in the Arctic marginal sea-ice zone could be performed from the research vessel Polarstern by two radiometers covering the frequency range from 22 to 243 GHz. At low frequencies, the brightness temperatures show clear signatures of different surface conditions. We estimate emissivities at 53∘ zenith angle from infrared-based skin temperatures. Predominantly vertically polarized 22–31 GHz emissivities are between 0.51 and 0.55 for open ocean and around 0.95 for sea ice. Predominantly horizontally polarized 243 GHz ocean emissivities are around 0.78 and ice surfaces exhibit a large variability from 0.67 to 0.82. Our results can improve the characterization of surface emissions in satellite retrieval algorithms.
Transferred Culpability and the Problem of Voluntary Intoxication
Authors: Tiffany Evan 
Published: January 2025

Abstract
This paper seeks to challenge principles of culpability transfer as they appear in both criminal law and moral philosophy. I begin by discussing the legal doctrine of substituted mens rea, focusing on Section 33.1 of Canada’s Criminal Code. I argue that this doctrine violates the principle of contemporaneity, which there are sound philosophical reasons to accept. I then argue that the same reasons apply to tracing accounts of moral responsibility. Finally, drawing on the moral luck literature, I argue that cases of extreme intoxication are better analyzed in terms of harm-causation than culpability-transfer.
Close and more distant relatives are associated with child mortality risk in historical Finland

Published: January 2025

Abstract
Humans are characterised as cooperative breeders, as not only the parents but also other members of the social group take part in raising offspring. The individuals who invest most in childrearing are usually the more closely related individuals. However, most studies have concentrated on close kin and the effects of more distant kin remain unknown. Here, we investigated the associations of child mortality (<5 years, n = 32,000 children) with the presence of 36 different types of relatives, divided by lineage and sex, in a historical Finnish population. We found that the presence and greater number of several paternal relatives were associated with an increase in child mortality and many of these associations were seen among the wealthiest families, due to inheritance practices and shared resources. The presence of the maternal grandmother was associated with a decrease in child mortality and the most among poorer families, who probably needed the grandmother’s contribution more than the wealthy. Our results bring new insights into the importance of kin and suggest that relatives can provide support or other resources but also compete for limited resources and care. The results give a broader perspective of human family life and increase understanding of the evolution of cooperative breeding.
Commemorating Dieter Henrich: Subjectivity and Metaphysics
Authors: Dews Peter 
Published: January 2025

Abstract
This article is a tribute to Dieter Henrich, the outstanding German philosopher, who died in December 2022. It begins by reviewing his life, academic career and general approach to philosophy. It then tracks the development of his theory of subjectivity, beginning with his classic article of the 1960s on ‘Fichte’s Original Insight’. Subsequent sections of the article consider critiques of Henrich’s position by prominent contemporaries and his response to them, his defence of the possibility of a metaphysics grounded in modern subjectivity, and his philosophy of religion.
Lip-Synching as an Account of Oneself: Digital Music Videos and the Voice–Gesture Relationship
Authors: DE ANDRADE LIMA DANIEL 
Published: January 2025

AbstractDigital-era music videos are a crucial part of singers’ mediatic performances. Lip-synching is often central to such products, supplying situations in which singers can mouth their voices while dislodging themselves from the struggles of singing. Looking into music videos by focusing on their lip-synching practices, this paper aims to understand the part voice takes on in the medium while also investigating how gestural lip-sync performances work as accounts of oneself that produce a musical subject, sometimes updating or overcoming social regulations. In this sense, lip-synching is theorized as a way of framing music videos’ gestural labour.
German Pharmaceutical Imperialism in Brazil: Cinchona, Biopolitics, and Hybrid Knowledge in the Early 19th Century
Authors: Labastida Rodriguez David 
Published: January 2025

Abstract
Between 1817 and 1831, four German scientists – Karl von Martius, Georg Langsdorff, Ludwig Riedel, and Friedrich Sello – undertook expeditions in Brazil with the goal of collecting natural specimens, particularly focusing on Brazilian cinchona plants. Renowned for their medicinal properties, especially in the treatment of fever diseases, cinchona specimens were extensively utilized by local Brazilian communities. The widespread use of cinchona raises important questions regarding how German scientists acquired knowledge of the therapeutic properties of plants, previously unknown within German pharmacology. This paper argues that the German understanding of Brazil's cinchona trees was situated within an imperialist endeavor that not only appropriated indigenous knowledge but also involved conducting experiments on these plants and their effects on local populations. This hybridization of knowledge about cinchona was characterized by an asymmetrical dominance of German pharmacological experimentation, which sought to enhance organic life and establish utopian, “healthy” German societies, in both German territories and Brazil. Consequently, German chemical experiments with Brazilian cinchona specimens intersected with biopolitical practices, aimed at manipulating both plant and human life through therapeutic interventions.
Effects of reduced nitrogen fertilizer application rates on grain yield and rice quality of early- and late-season dual-use rice in South China

Published: January 2025

Abstract
Reducing nitrogen (N) fertilizer application is a sustainable practice in rice production. The effects of reducing N fertilizer input on grain yield and rice quality of early- and late-season dual-use rice (ELDR) in South China remain uncertain. Therefore, a short-term field trial was conducted with a high-yielding ELDR cultivar (Yuehesimiao, YHSM) and a low-yielding ELDR cultivar (Meixiangzhan 2, MXZ). The rice was cultivated with a 20% reduced N application rate (RN2), a 10% reduced rate (RN1) and the conventional N application rate (CN). In the early season, compared to CN, RN2 reduced the grain yield of YHSM and MXZ by an average of 16.1 and 6.6%, respectively, while RN1 lowered YHSM grain yield by 11.2% on average and had no effect on MXZ yield. In addition, RN2 decreased the milling and eating qualities of the two cultivars in the early season, while RN1 did not alter their milling, appearance or eating qualities. In the late season, neither RN2 nor RN1 affected grain yield or rice quality for both cultivars. Therefore, short-term reductions of 10 and 20% in N application could maintain grain yield and rice quality at current N fertilizer application rates in the late season. However, the early-season results only recommended a 10% reduced N fertilizer application rate for low-yielding ELDR cultivars to sustain grain yield and rice quality. The findings of this study can provide a theoretical basis for N management of ELDR in South China.
Different paths to multilingualism in Autism Spectrum Disorder (ASD): Naturalistic and non-interactive
Authors: Hindi Iris , Meir Natalia 
Published: January 2025

Abstract
This study is one of the few research efforts investigating unexpected non-interactive foreign language acquisition in children with Autism Spectrum Disorder (ASD). Participants included 46 English-Hebrew-speaking children (ages 4;10 to 12;0): 14 autistic children who acquired English via non-interactive input (ASD-NI); 12 autistic children (ASD-Nat), and 20 non-autistic children with typical language development (TLD-Nat) who acquired English and Hebrew naturalistically. Morpho-syntactic abilities were assessed using Sentence Repetition tasks in both languages. The results showed no group differences for morpho-syntax in English; in Hebrew, the ASD-NI group scored similarly to the ASD-Nat group but lower than the TLD-Nat group. Individual performance differences between Hebrew and English were observed across all groups. Additionally, correlations between exposure and SRep scores were found in both groups for Hebrew but not English. These findings highlight diverse paths to language acquisition in ASD, with children acquiring foreign languages via both naturalistic and non-interactive input.
Testing ChatGPT in International Relations Classrooms: Potentialities, Limitations, and What’s Next
Authors: Rivetti Paola , Banerjee Rituparna , O’Mullane David 
Published: January 2025

ABSTRACTWhereas significant attention has been devoted to online/blended teaching and related tools, open GenAI chatbots and large language models and writing programs have received comparatively less attention as instruments that impact our teaching and assessment methods. The pedagogies of political science and international relations somehow trail behind in understanding and addressing them. For those who are teaching these subjects, it is of great importance to come to terms with AI and its impact on how we should assess students. This article describes an eight-week laboratory during which we experimented with and discussed ChatGPT’s utilizations with our students. The goal of the laboratory was to revise which type of learning objectives our teaching should have and which type of assessment methods are best suited for an environment in which GenAI is present and used regularly. Should we ban it or should we instead focus on teaching students how to use it responsibly and ethically, as well as developing a shared understanding of what GenAI is good for (if anything at all)? Consequently, which learning objectives and assessment methods should we adopt?
Elite Interviewing as an In-Betweener
Authors: Menzies Loic 
Published: January 2025

ABSTRACT
Conducting elite interviews presents well-documented challenges, often linked to dynamics that are influenced by researchers’ status. This aspect of positionality is sometimes characterized as “insider” or “outsider” status, but scholars have noted the lack of nuance in this rigid binary. Drawing on experiences during interviews with policy elites—primarily in England—this article describes the author’s “in-betweener” status and reviews four methodological considerations from this perspective, highlighting the challenges and opportunities associated with different points on the insider–outsider spectrum. These observations are meant to stimulate reflexivity among researchers regardless of their status.

Published: January 2025

Abstract
In this paper, the design and optimization of a circularly polarized antenna based on two crossed dipoles in phase quadrature for Global Navigation Satellite System (GNSS) wide band application has been investigated. The proposed design is single fed and relies on parasitic structures to achieve wide band coverage on the GPS standard bands L1 (1559–1610 MHz) and L5 (1164–1189 MHz). Full-wave simulations have been used to compute the radiation properties and the impedance of the antenna. A prototype was manufactured, and good agreement has been observed between the simulated results and measurement for both radiation pattern and reflection coefficient.
The antenna achieves a −10 dB impedance bandwidth of

$56.97\%$

covering the band 1164–1610 MHz, and an axial ratio that covers the L5 band ranging between 7 dB and 2.8 dB from 1.164 GHz to 1.3 GHz while maintaining a value below 2.7 dB across the entire L1 band. The antenna occupies a volume of

$\,99\, \,\times\,99\, \times 50$

mm3. It has been tested in real conditions during the 23rd French National Microwave Days (JNM) student competition. A GNSS signal receiver has been connected to the antenna. The antenna has been evaluated based on the number of connections it could achieve over a duration of 30 s.
Inverse Energy Cascades in the Boundary Layer During Strong Winds Based on Doppler Lidar
Authors: Zhou Xingxu , Zhang Chao , Xiao Ziniu , Li Yunying , Lu Gaopeng 
Published: January 2025

AbstractInverse energy cascade (IEC), where energy moves from small to large eddies, has been debated, with limited observational evidence. This study used 19 months of Doppler Lidar data from Qingdao, China, to examine IEC associated with gusts. We found IECs occurred 15% of the time at 50 m height. When near‐surface wind speeds exceeded 11 m·s−1, IEC frequency and intensity increased, indicating that strong winds are a critical driver of IEC. This study suggests that the reduction in the drag coefficient under high wind conditions may generate IEC and gusts, consequently influencing energy transfer throughout the boundary layer and lower troposphere. Analysis using the four‐quadrant model revealed IECs are linked to changes in momentum from ejections and inward interactions, even in weak background fields. The study supports that IECs are more prevalent and highlights their role in the lower atmosphere, contributing to an improved understanding of land‐atmosphere coupling.

Abstract
Fibrotic remodeling of nucleus pulposus (NP) leads to structural and mechanical anomalies of intervertebral discs that prone to degeneration, leading to low back pain incidence and disability. Emergence of fibroblastic cells in disc degeneration has been reported, yet their nature and origin remain elusive. In this study, we performed an integrative analysis of multiple single-cell RNA sequencing datasets to interrogate the cellular heterogeneity and fibroblast-like entities in degenerative human NP specimens. We found that disc degeneration severity is associated with an enrichment of fibrocyte phenotype, characterized by CD45 and collagen I dual positivity, and expression of myofibroblast marker α-smooth muscle actin. Refined clustering and classification distinguished the fibrocyte-like populations as subtypes in the NP cells - and immunocytes-clusters, expressing disc degeneration markers HTRA1 and ANGPTL4 and genes related to response to TGF-β. In injury-induced mouse disc degeneration model, fibrocytes were found recruited into the NP undergoing fibrosis and adopted a myofibroblast phenotype. Depleting the fibrocytes in CD11b-DTR mice in which myeloid-derived lineages were ablated by diphtheria toxin could markedly attenuate fibrous modeling and myofibroblast formation in the NP of the degenerative discs, and prevent disc height loss and histomorphological abnormalities. Marker analysis supports that disc degeneration progression is dependent on a function of CD45+COL1A1+ and αSMA+ cells. Our findings reveal that myeloid-derived fibrocytes play a pivotal role in NP fibrosis and may therefore be a target for modifying disc degeneration and promoting its repair.
