Pattern scaling of simulated vegetation change in North Africa during glacial cycles
Authors: Duque-Villegas Mateo , Claussen Martin , Kleinen Thomas , Bader Jürgen , Reick Christian H.
Published: September 2024

Abstract. Over the last hundreds of millennia natural rhythms in Earth's astronomical motions triggered large-scale climate changes and led periodically to humid conditions in much of North Africa. Known as African humid periods (AHPs), such times sustained river networks, vegetation, wildlife and prehistoric settlements. Mechanisms, extent and timing of the changes still cannot be completely outlined. Although AHPs along glacial cycles are recognizable in long marine sediment records, the related land cover changes are difficult to reconstruct due to scarcity of proxy data over the continent. Moreover, most available information covers only the latest AHP during the Holocene. Here we use a comprehensive Earth system model to look at additional, much earlier, possible cases of AHPs. We simulate the full last glacial cycle, aiming to reproduce the last four AHPs as seen in available proxies. The simulated AHPs seem in broad agreement with geological records, especially in terms of timing and relative strength. We focus on the simulated vegetation coverage in North Africa and we detect a dominant change pattern that seems to scale linearly with known climate forcing variables. We use such scaling to approximate North African vegetation fractions over the last eight glacial cycles. Although the simple linear estimation is based on a single mode of vegetation variability (that explains about 70 % of the variance), it helps to discuss some broad-scale spatial features that had been only considered for the Holocene AHP. Extending the climate simulation several millennia into the future reveals that such pattern scaling breaks when greenhouse gases become a stronger climate change driver.

Abstract. A relative calibration technique is developed for the U.S. Department of Energy's (DOE) Atmospheric Radiation Measurement (ARM) user facility Ka-Band ARM Zenith Radars (KAZRs). The technique utilizes the signal attenuation due to water collected on the radome for estimates of the reflectivity factor (Ze) offset. The wet-radome attenuation (WRA) is assumed to follow a logarithmic relationship with rainfall rate in light and moderate rain conditions, measured by a collocated surface disdrometer. A practical advantage of this WRA approach to shorter-wavelength radar monitoring is that while it requires a reference disdrometer, it is shown viable for a wider range of collocated disdrometer measurements than traditional disdrometer direct comparisons in light rain. Adding such techniques may provide an additional, cost-effective monitoring tool for remote/longer-term deployments. This technique has been applied during the ARM TRacking Aerosol Convection interactions ExpeRiment (TRACER) from October 2021 through September 2022. The estimated offsets in Ze are evaluated against traditional radar calibration and monitoring methods based on datasets available during this campaign. This WRA technique reports offsets that compare favorably with the mean offsets found between the cloud radars and a nearby disdrometer near the time of rain onset, while also demonstrates similar offset and campaign-long trends with respect to collocated and independently-calibrated reference radars. Overall, the KAZR Ze offsets estimated during TRACER remains stable and at a level 2 dBZ lower than the Ze estimated by disdrometer from the campaign start until the end of June 2022. Thereafter, the radar offsets increase to near 7 dBZ at the end of the campaign.

Abstract. Differentiating between snow and rainfall is crucial for hydrological modeling and understanding. Commercial Microwave Links (CMLs) can provide accurate rainfall estimates for liquid precipitation, but show minimal signal attenuation during dry snow events, causing the CML time series during these periods to resemble non-precipitation periods. Weather radars can detect precipitation also for dry snow, yet, they struggle to accurately differentiate between precipitation types. This study introduces a new approach to improve rainfall and dry snow classification by combining weather radar precipitation detection with CML signal attenuation. Specifically, events where the radar detects precipitation, but the CML does not, are classified as dry snow. As a reference method we use weather radar, with the precipitation type identified by the dew point temperature at the CML location. Both methods were evaluated using ground measurements from disdrometers within 8 km of a CML, analysing data from 550 CMLs in December 2021 and 435 CMLs in June 2022. Our results show that using CMLs can enhance the classification of dry snow and rainfall, presenting an advantage over the reference method. Further, our research provides valuable insights into how precipitation at temperatures around zero degrees, such as sleet or wet snow, can affect CMLs, contributing to a better understanding of CML applications in colder climates.

Abstract. Biomass burning is a major global source of both primary brown carbon (BrC) and reactive trace gases in the atmosphere, thus exerts significant impacts on global climate and regional atmospheric chemistry. However, a substantial gap remains in our understanding of the nighttime evolution of biomass burning emissions. Here we present prominent nighttime formation of secondary organic aerosol (Night-OA) with strong absorptivity but markedly different spectral dependence from that of primary biomass burning organic aerosols, which was observed during autumn of the Pearl River Delta region of China when biomass burning plumes prevailed. Our results demonstrate that the formation of Night-OA appeared high dependence on both magnitudes of afternoon biomass burning emissions and available oxidants of NO2 and O3. Active nighttime NO3 radical chemistry was characterized by quick O3 depletion and almost zero concentration of NO, and the rapid decrease of NO2 coincident with the quick nitrate formation suggests that the rapid NO2 consumption supplied the NO3 and N2O5 reaction chains. However, the quickest Night-OA formation occurred when nitrate formation ceased and relative humidity reached maximum, and mainly added mass to aerosol water abundant diameter ranges. This co-variation demonstrates that gas-phase and aqueous-phase chemistry of biomass burning precursors likely coordinated to promote the quick nighttime formation of Night-OA. Findings of this study highlight the nighttime darkening of biomass burning plumes through multiphase reactions and the proposed secondary BrC formation mechanisms may have broad implications in climate and air quality effects of biomass burning, such as the interaction between biomass burning plumes with water abundant pyroconvection cloud.
Impact-based temporal clustering of multiple meteorological hazard types in southwestern Germany
Authors: Küpfer Katharina , Tuel Alexandre , Kunz Michael
Published: September 2024

Abstract. A series of multiple meteorological extreme events in close succession can lead to a substantial increase in total losses compared to randomly distributed events. In this study, different temporal clustering methods are applied to insurance loss data on southwestern Germany from 1986 to 2023 for the following hazards: windstorms, convective gusts, hail, as well as pluvial, fluvial and mixed flood events. We assess the timing and significance of seasonal clustering of single hazard types as well as their serial combination by use of both a simple counting algorithm and the clustering metric Ripley's K. Results show that clusters of damaging hazards occur mainly during May–August. Although clustering is significant only for certain hazard types compared to a random process, clustering is robust for a combination of multiple hazard types, namely hail, mixed or pluvial floods and storms. This particular combination of hazard types is also associated with higher losses compared to their isolated occurrence. Clustering results also depend on the method of defining independent events (Peaks-over-Threshold with flexible lengths vs. Hours Clause with fixed lengths) and their resulting duration. This study demonstrates the relevance of considering multiple hazard types when evaluating clustering of meteorological hazards.

Abstract. The current climate emergency and the related energy transition require the development of technology producing zero-carbon energy. One viable option entails the utilization of recyclable metal fuels. The primary energy stored by the reduction in metal oxides can be transported and later released by metal combustion. Mg is among the most promising metal as a regenerable energetic vector, having an energy density of 25 MJ kg−1. The exploitation of the Mg oxidation and reduction loop has recently been demonstrated, and the loop combustion products are made of metal oxides. The mineralogical characterization of the MgO crystals generated by the Mg combustion is of utter importance for the optimization of the particle trapping capacity in the combustion system during the closed oxidation and reduction loop. In this paper we characterize MgO particles generated in a swirl-stabilized Mg flame by using powder X-ray diffraction, transmission electron microscopy and selected area electron diffraction, and atomic-resolution microscopy combined with energy-dispersive X-ray spectroscopy and dual-electron energy-loss spectroscopy. The MgO combustion products were chemically homogeneous at this level of investigation. Three representative morphologies (cubic, truncated octahedron, and spherical) and two isostructural phases were identified in the MgO combustion product. These findings may contribute to the optimization of system development, particularly in terms of the collection efficiency of the combustion end product.
Bushfire effects on soil properties and post-fire slope stability: the case of the 2015 Wye River-Jamieson Track bushfire
Authors: Li Yuanying , Wakai Akihiko , Costa Susanga
Published: September 2024

Abstract. Bushfire is a destructive natural disaster that leads to vegetation loss and increased soil infiltration. Over a long post-fire period, root death and reduced reinforcement decrease soil shear strength. During rainfall, shallow landslides in burned areas become more frequent and widespread. This study focused on Wye River and Separation Creek in Australia, affected by the 2015 Wye River-Jamieson Track bushfire. Ten months after the bushfire, multiple slope failures, including the Paddy’s Path landslide, occurred during heavy rains from 12 to 14 September 2016, disrupting the Great Ocean Road connecting towns. This study aims to assess changes in slope stability during rainfall before and after the bushfire. Controlled laboratory burning tests simulated bushfire effects on soil, resulting in changed soil properties after the fire: increased permeability due to soil particle coarsening and reduced soil shear strength, especially cohesion. Considering the changes in soil properties before and after the fire, a simplified hydrological numerical model for infiltration calculation was employed to analyze time-dependent changes in groundwater level depth, surface water depth, and safety factor during rainfall. Comparing pre- and post-fire results indicated higher susceptibility to shallow slope failures in burned areas, with rapid rises in groundwater level and surface water acting as triggers. These findings enhance the understanding of landslide triggering mechanisms in post-fire slopes and provide insights for mapping landslide susceptibility in bushfire-prone regions.
Brief communication: Small-scale geohazards cause significant and highly variable impacts on emotions
Authors: Ilyinskaya Evgenia , Snæbjarnarson Vésteinn , Carlsen Hanne Krage , Oddsson Björn
Published: September 2024

Abstract. The impact of geohazards on the mental health of local populations is well recognised but understudied. We used natural language processing (NLP) of Twitter (now known as X) posts (n=10 341) to analyse the sentiments expressed in relation to a pre-eruptive seismic unrest and a subsequent volcanic eruption in Iceland in 2019–2021. We show that although these geohazards were of a small size and caused negligible material damage, they were associated with a measurable change in expressed emotions in the local population. The seismic unrest was associated with predominantly negative sentiments (positive-to-negative sentiment ratio of 1:1.3), but the eruption was associated with predominantly positive sentiments (positive-to-negative sentiment ratio of 1.4:1). We demonstrate a cost-effective tool for gauging public discourse that could be used in risk management.
On dissipation timescales of the basic second-order moments: the effect on the energy and flux budget (EFB) turbulence closure for stably stratified turbulence
Authors: Kadantsev Evgeny , Mortikov Evgeny , Glazunov Andrey , Kleeorin Nathan , Rogachevskii Igor
Published: September 2024

Abstract. The dissipation rates of the basic second-order moments are the key parameters playing a vital role in turbulence modelling and controlling turbulence energetics and spectra and turbulent fluxes of momentum and heat. In this paper, we use the results of direct numerical simulations (DNSs) to evaluate dissipation rates of the basic second-order moments and revise the energy and flux budget (EFB) turbulence closure theory for stably stratified turbulence. We delve into the theoretical implications of this approach and substantiate our closure hypotheses through DNS data. We also show why the concept of down-gradient turbulent transport becomes incomplete when applied to the vertical turbulent flux of potential temperature under stable stratification. We reveal essential feedback between the turbulent kinetic energy (TKE), the vertical turbulent flux of buoyancy, and the turbulent potential energy (TPE), which is responsible for maintaining shear-produced stably stratified turbulence for any Richardson number.
A large-eddy simulation analysis of collective wind-farm axial-induction control in the presence of blockage
Authors: Delvaux Théo , Meyers Johan
Published: September 2024

Abstract. Over the past few years, numerous studies have shown the detrimental impact of flow blockage on wind-farm power production. In the present work, we investigate the benefits of a simple collective axial-induction control strategy on power maximization and load reduction in the presence of blockage. To this end, we perform a series of large-eddy simulations (LES) over a wind-farm consisting of 100 IEA 15MW turbines, and build the wind-farm power and thrust coefficient curves for three different conventionally neutral boundary layer profiles. We show that the wind-farm power and thrust coefficient curves are much flatter than those of an isolated turbine. As a result, the wind-farm thrust coefficient becomes significantly more sensitive to the selected operating point than the power coefficient. Consequently, we find that the optimal wind-farm operating point considerably differs from the Betz limit in practice, particularly under high-blockage conditions. At the optimal point, the results reveal a minor power increase, accompanied by a load reduction of about 5 %, simultaneously. More interestingly, we show that in some cases the loads can be reduced by up to 19 %, at the expense of a power decrease of only 1 %.

La peinture dans ma pratique du cinéma d’animation
Authors: Corriveau Thomas
Published: September 2024

Il y a plus de quarante ans, je me suis dirigé vers ce que j’imaginais être une carrière exclusivement consacrée à la pratique de la peinture. Au cours de mes études universitaires, et ce à mon grand étonnement, je me suis intéressé au cinéma d’animation, au point de développer une démarche artistique qui puisse conjuguer la création d’œuvres picturales et la production de films. J’ai peint en me basant amplement sur des concepts empruntés au cinéma et j’ai conçu des films comme s’il s’agissait de tableaux. En replongeant dans la genèse des films que j’ai réalisés entre 1981 et aujourd’hui, je propose ici quelques pistes de réflexion sur les interactions permanentes et fructueuses entre ces deux champs de création dans mon œuvre.
Le portrait : transfiguration de la seconde chance
Authors: André Baptiste
Published: September 2024

L’article se propose d’observer un phénomène récurrent au sein des productions hollywoodiennes classiques, et plus particulièrement entre 1944 et 1948. En effet, plusieurs films utilisent le portrait comme un élément narratif essentiel au déroulement de leur trame. Le motif d’un portrait peint agit comme un objet à valeur esthétique forte, il est l’épicentre, la condition même, d’un retour à soi (en l’occurrence aux personnages) et d’une possibilité d’une seconde chance. Récits entremêlés, acteurs et actrices qui passent d’un film à l’autre, sont alors autant de symptômes vers lesquels le portrait peint converge. Cette constellation qui se répète dans un corpus singulier nous pousse à voir dans le portrait un objet dont les propriétés picturales transfigurent le medium cinématographique et attire notre attention sur une autre façon d’être au monde, celle d’une seconde fois, d’une nouvelle présence. L’article a ainsi pour champ de recherche et d’analyse les conditions de cette transfiguration, les moyens de ses apparitions et ses conséquences sur le médium et les récits qu’elle habite.
Construcciones con relativos desplazados en español: una propuesta de análisis desde la macrosintaxis
Authors: Degli Uomini Mariano Claudio
Published: September 2024

En este trabajo se estudia, desde una perspectiva macrosintáctica, un fenómeno denominado de distintas maneras a través de los años: relativo desplazado, relativa compleja, configuración relativa envolvente o extraposición del relacionante. Si bien la configuración ha sido estudiada desde la microsintaxis, se puede considerar que una perspectiva que entienda el fenómeno como estructuración vinculada con la macoestructura de determinadas secuencias textuales —específicamente, informativas y argumentativas— puede permitir una caracterización más acabada del fenómeno. Como se muestra en el análisis que toma en consideración los aportes de avances concretos de estudios de macrosintaxis en español, en muchos casos la introducción de las estructuras mencionadas y la consecuente presencia de verbos puente en determinados enunciados supone una toma de distancia respecto de lo referido o una falta de compromiso en relación con la verdad expuesta en la segunda proposición subordinada. En otro grupo de ejemplos, la toma de distancia actúa, además, como una puesta en duda —o negación— de lo mencionado, de manera tal que la configuración opera sobre el posible valor argumentativo de la información.

A lo largo de su obra, Louis Althusser elabora distintas concepciones de la filosofía. En la Conferencia de Granada de 1976, Althusser consuma el proceso de autocrítica que le había llevado a retractarse de sus posiciones iniciales y a introducir la noción de explotación como concepto clave para comprender la práctica filosófica. El objeto de este trabajo es doble. En primer lugar, se trata de esclarecer el vínculo que Althusser establece entre filosofía y explotación, haciendo explícito el modo en que la filosofía explota a las prácticas sociales y a las ciencias. En segundo lugar, nos proponemos ofrecer una lectura de la nueva práctica de la filosofía esbozada por Althusser como una práctica socialista y democrática de la filosofía.

The Turks, who migrated to Europe as "guest workers" in the 1960s, have settled in Europe. The majority of Turks who migrated to Europe currently live in Germany. In order to strengthen the ties of Turkish students living in Germany with the Turkish language and Turkish culture, the Ministry of National Education of the Republic of Turkey initiated "Turkish Language and Turkish Culture" courses in schools located in Germany. Teachers from Turkey have been appointed to provide this education. The inability of children from Turkish immigrant families to fully learn both German and their mother tongue negatively affects their social lives as well as their academic success. Consequently, this leads to educational problems. The aim of this study is to evaluate the motivation processes faced by bilingual and Turkish-origin children living and receiving education in Germany during their Turkish language learning process.

The cultivation system using hydroponics is now widely popular among the community because it does not require large areas of land. Using the hydroponic system results in faster and optimal harvests. However, the busy activities of urban communities often cause them to fail in implementing it due to constraints in controlling and monitoring hydroponic plants. Additionally, PLN electricity is essential for operating the water pump, and the electricity load and tariff increases, along with sudden blackouts, significantly impact business actors. To address this problem, this research creates an Internet of Things (IoT)-based water monitoring system for ACONE Hydroponics partners with solar panel (PLTS) energy sources as an alternative energy in the event of a sudden PLN power outage. The sensors used in this system include the HCR-04 ultrasonic sensor to monitor water availability and the water flow sensor to measure water flow (discharge). Sensor data is processed by the ESP32 microcontroller and sent to the Blynk cloud platform via an internet connection and displayed on an LCD. System testing shows that the system can send sensor data to the cloud platform stably and in real-time. Data visualization on the cloud platform is easy to understand and helps hydroponic owners monitor water conditions in hydroponic systems. This water monitoring system can help users optimize water use in hydroponic systems.
Lightweight den boxes enhance habitat for pine martens Martes martes in a conifer plantation in south-west Scotland
Authors: Croose Elizabeth , Martin John , Johnstone Stephanie , Birks Johnny D.S.
Published: September 2024

The European pine marten Martes martes typically occupies woodland and preferentially rests and breeds in arboreal, insulated den sites, which are particularly critical for breeding females. An absence of elevated cavities may force pine martens to use suboptimal den sites, and consequently limit population distribution, abundance, and breeding success. Artificial den boxes have been designed and installed in recent years and occupied by both non-breeding and breeding pine martens. However, the large size and weight of these boxes makes them too heavy to use in young forestry plantations. We tested two smaller, lighter box designs (the Galloway Lite Mk1 (‘GLMk1’) and Galloway Lite Mk2 (‘GLMk2’)) that could be more easily deployed in commercial conifer plantations. Fifty boxes of each design were installed in Galloway Forest, south-west Scotland, and monitored for evidence of pine marten occupation and breeding. Overall, GLMk2 boxes were occupied more frequently than the GLMk1 boxes, including for breeding. The Galloway Lite boxes provide a lightweight, economical and practical option for increasing the availability of elevated den sites for pine martens and can be deployed as a conservation tool to enhance habitat conditions.

Published: September 2024

Entre las dificultades a las que se ha enfrentado el Tercer Sector de la Comunicación (TSC) se encuentra su falta de integración en los contenidos de las asignaturas en los grados en Periodismo. Esta ausencia, que se acentúa en el caso de las asignaturas de Historia de la Comunicación o Historia del Periodismo, impide que el estudiantado pueda comprender los procesos de comunicación alternativos desarrollados a lo largo de las últimas décadas. Las causas son variadas, pero destacamos el encorsetamiento de los temarios a espacios temporales muy condensados y la falta de inclusión del Tercer Sector de la Comunicación en los manuales de las asignaturas. Este capítulo aborda brevemente la historia del TSC en España con el objetivo de estudiar los principales acontecimientos en su evolución y reivindicarlo como objeto de estudio. Pretendemos facilitar al docente el acceso a contenidos en torno al TSC —siempre con la vista puesta en las relaciones entre el poder y la comunicación— y elaborar una propuesta que lo incluya en las asignaturas de Historia de la Comunicación.

Stress Detection through EEG Signals: Employing a Hybrid Approach integrating Time Domain, Frequency Domain Features and Machine Learning Techniques
Authors: Ankita Gandhi
Published: September 2024

Mental stress is a widespread problem that affects people all over the world and can have negative health consequences if not appropriately controlled. The importance of early detection and management in minimizing the detrimental effects of stress cannot be overstated. This study provides a hybrid technique for stress detection that combines time domain and frequency domain information taken from EEG data. Machine learning techniques are used to create a stress detection model that is accurate and dependable. The goal is to increase the accuracy and reliability of stress detection so that prompt intervention and assistance may be provided. The paper opens with an introduction to stress, its effects on mental health, and the need for automated stress detection systems. EEG signals are introduced as a valuable data source for recording stress-related brain activity. To test the model's success in stress detection, performance evaluation criteria such as accuracy, sensitivity, specificity, and F1-score are used. When the result compared to the present approach, the Hybrid Approach has higher accuracy (SVM-98.33% & RF-95%).

Proses penciptaan seni pertunjukan teater selalu diawali dengan pencarian sebuah ide. Dalam pencarian ide seorang aktor sering terinspirasi dari pengalaman di kehidupan sehari-hari. Pada umumnya proses penciptaan pertunjukan teater berawal dari naskah atau cerita yang dipentaskan, namun pada kenyataannya sebuah karya bisa dicetuskan dari berbagai hal, salah satunya melalui kegiatan seminar. Artikel ini akan menguraikan karya pertunjukan yang berasal dari pencarian ide dan proses kreatif penulis untuk membuat pertunjukan melalui presentasi seminar. Penelitian ini menggunakan metode kualitatif dengan pendekatan kepada proses latihan di lapangan. Riset artistik dilakukan oleh seorang aktor melalui penjelajahan dalam ruang keseharian. Tujuan penelitian yang dilakukan ini menjadi semacam pemetaan seorang aktor dalam seluruh proses pencarian ide. pemetaan ini menghasilkan ruang kreatif untuk kemudian menjadi struktur dalam sebuah pertunjukan teater. Teknologi berperan penting mengisi ruang ekspresi utama dalam penyampaian materi pertunjukan. Kehadiran multimedia (audio visual) sebagai penghubung antara aktor di atas panggung dan peristiwa luar panggung menjadi sebuah kebaruan pada karya ini. Hasil penciptaan karya ini adalah pertunjukan teater seminar yang dipentaskan di gedung pertunjukan oleh seorang aktor dengan permainan multimedia.

Intra-crystalline protein degradation (IcPD) analysis was undertaken on 80 fossil tooth enamel samples from four taxonomic groups (rhinocerotid, suid, equid, bovid) excavated from two archaeological cave sites in Zambia (Twin Rivers and Mumbwa Caves). Seventy-two (90%) of these fossils showed evidence of closed-system behaviour. The fossils’ relative extent of protein degradation between the sites was consistent with their known ages, with samples from Twin Rivers (Mid-Pleistocene) showing higher levels of degradation than Mumbwa Caves (late Mid-Pleistocene to late Holocene). At Twin Rivers, a potential trend between IcPD and excavation depth was observed, concordant with the working hypothesis of periodic deposition of sediments as slurry flows into a phreatic passage. However, greater depositional and taphonomic complexity was indicated by relatively wide ranges of IcPD values within individual excavation levels. These results are interpreted partly as the consequence of the excavation methods used, alongside reworking within the deposits, which had not previously been recognised. Whilst lack of stratigraphic control limited the investigation of taxonomic effect, one notable difference in the protein breakdown pattern of peptide chain hydrolysis was observed between rhinocerotid in comparison to the other studied taxa. We therefore recommend taxon-specific enamel amino acid geochronologies (AAGs) are developed in future. Whilst lack of comparator datasets meant it was not possible to create a calibrated, enamel AAG for the South-Central African region from these sites, Twin Rivers provides a case study illustrating the complexity of cave formation processes and the importance of direct dating for interpreting archaeological and palaeontological sequences.
