Published: February 2025

Abstract. The Mediterranean Basin is identified as a climate change hotspot and prone to future drying. Previous studies indicate that the effect of forests on precipitation remains unclear for the Mediterranean Basin specifically. Here we use a simple model to simulate the development of the atmospheric boundary layer (ABL) to determine the impact of forest on convective rainfall potential. There is convective rainfall potential when (1) the ABL reaches the lifting condensation level, and (2) there is sufficient convective available potential energy. We model the ABL development over the Mediterranean Basin covered fully with bare soil and forest to determine its land cover sensitivity. In addition, we examine the sensitivity of the ABL to variations in soil moisture for the forest scenario specifically. We identify two distinct responses to forestation in the Mediterranean Basin dependent on soil moisture content. Forestation contributes to warming and drying in relatively dry regions (low soil moisture content) and to cooling and wetting in relatively wet regions (high soil moisture content), indicating that dry gets drier and wet gets wetter. We find that both forestation and an increase in soil moisture can contribute to convective rainfall potential. In regions with a relatively high soil moisture content, forestation positively influences both the convective available potential energy, and the crossing of the ABL and lifting condensation level. The results show that forestation in the Mediterranean Basin may reduce future drying in relatively wet regions and enhance future drying in relatively dry regions.

Published: February 2025

Abstract. Global warming induced alterations in ocean temperature regimes, and precipitation patterns are increasingly impacting coastal ecosystems, leading to shifts in water column properties. These changes may have profound implications for microbial communities such as methane-oxidising bacteria (MOBs), which play a critical role in regulating methane fluxes and ecosystem dynamics. In this study, we investigate the resilience and adaptability of aerobic MOBs in response to changing environmental conditions. Through microcosm incubation experiments with waters from the North Sea and the Wadden Sea collected during different seasons, we explore how variations in methane availability, temperature, and salinity influence the MOB community structure and functional capacity. Our results reveal an increase in the relative abundance of MOBs to up to 57 % in experiments with elevated methane concentrations, highlighting the primary role of methane availability for MOB community development. Temperature and salinity variations, on the other hand, exerted lesser effects on MOB composition and relative abundance. A strong effect on MOB community development was furthermore caused by the origin of the inoculum (location and season). Our results thus suggest a functional redundancy in the variable pools of microbial inocula enabling multiple MOB clades to cope with drastic changes in environmental parameters. The adaptability of MOB communities is key to understand their role in mitigating methane emissions from coastal regions in a future ocean with potentially elevated methane, temperature and variable salinity levels.
Explicit simulation of reactive microbial transport with a dual-permeability, two-site kinetic deposition formulation using the integrated surface-subsurface hydrological model HydroGeoSphere
Authors: Currle Friederike , Therrien René , Schilling Oliver S.
Published: February 2025

Abstract. Assessing the transport behavior of microbes in surface water-groundwater systems is important to prevent contamination of drinking water resources by pathogens. While wellhead protection area (WHPA) delineation is still predominantly based on dye injection tests and advective transport modeling, size exclusion of colloid-sized microbes from the smaller and usually less conductive pore space causes a faster breakthrough and thus faster apparent transport of microbes compared to that of solutes. To provide a tool for better assessment of the differences between solute and microbial transport in surface water-groundwater systems, we here present the implementation of a dual-permeability, two-site kinetic deposition formulation for microbial transport in the integrated surface-subsurface hydrological model HydroGeoSphere (HGS). The implementation considers attachment, detachment and inactivation of microbes in both permeability regions and allows for multispecies transport. The dual-permeability, two-site kinetic deposition implementation in HGS was verified against an analytical solution for dual-permeability colloid transport and the suitability of the model for microbial transport at the wellfield scale is illustrated in a multi-tracer flow and transport study of an idealized alluvial riverbank filtration site. In this illustrative example, the transport of reactive microbes, conservative 4He, and reactive 222Rn was simulated in parallel, allowing mixing ratios, tracer breakthrough curves and travel times to be assessed via multiple approaches. The developed simulation tool is the first integrated surface-subsurface hydrological simulator for reactive solute and microbial transport, and marks an important advancement to unlock and quantify governing microbial transport processes in riverbank filtration settings. It enables meaningful WHPA delineation and risk assessments even under extreme hydrological situations such as flood events.

Published: February 2025

Abstract. In situ measurements of particulate inherent optical properties (IOPs) – absorption (ap(λ)), scattering (bp(λ)), and beam attenuation (cp(λ)) – are crucial for the development of optical algorithms that retrieve biogeochemical quantities such as chlorophyll a, particulate organic carbon (POC), and total suspended matter (TSM). Here we present a compilation of particulate absorption–attenuation spectrophotometric data measured underway on nine Atlantic Meridional Transect (AMT) cruises between 50° N and 50° S from 2009–2019. The compilation includes coincident high-performance liquid chromatography (HPLC) phytoplankton pigment concentrations, which are used to calibrate transects of total chlorophyll a (Tot_Chl_a) concentrations derived from the ap(λ) line-height method. The IOP data are processed using a consistent methodology and include propagated uncertainties for each IOP variable, uncertainty quantification for the Tot_Chl_a concentrations based on HPLC match-ups, application of consistent quality-control filters, and standardization of output data fields and formats. The total IOP dataset consists of ∼310 000 measurements at a 1 min binning (∼270 000 hyper-spectral) and >700 coincident HPLC pigment surface samples (∼600 of which are coincident with hyper-spectral IOPs). We present the geographic variation in the IOPs, HPLC phytoplankton pigments, and ap-derived Tot_Chl_a concentrations which are shown to have uncertainties between 8 % and 20 %. Additionally, to stimulate further investigation of accessory pigment extraction from ap(λ), we quantify pigment correlation matrices and identify spectral characteristics of end-member ap(λ) spectra, where accessory pigment groupings are present in higher concentrations relative to Tot_Chl_a. All data are made publicly available in SeaBASS and NetCDF formats via the following links: https://seabass.gsfc.nasa.gov/archive/PML/AMT (Jordan et al., 2025a) and https://doi.org/10.5281/zenodo.12527954 (Jordan et al., 2024).

Authors: Simoes-Sousa Iury T. , Rocha Cesar , Tandon Amit , Schmidt Andre
Published: February 2025

Abstract. Satellite altimetry has revolutionized our understanding of ocean physics by providing global sea-surface height data. These measurements reveal the intricate dynamics of ocean mesoscale strain and vortices, and their interactions with multiple physical scales in the oceans. Although surface dynamics has been extensively studied, investigating the vertical structure of mesoscale eddies globally remains a computational challenge. In this study, we combine the comprehensive World Ocean Database (WOD) with a database of Eulerian mesoscale eddies (META3.2 DT). We pre-process and filter the WOD data, selecting quality controlled profiles at local depths greater than 100-m. By integrating WOD data with altimetry-derived mesoscale eddies, we aim to facilitate future studies on the role of mesoscale vortices in multiple processes, such as heat, mass and nutrient transport, and water-mass subduction. The analysis is performed using high-performance computing resources, with Python packages for parallel processing of the data and analysis of more than 4.2 million profiles with more than 35 million vortex observations. The dataset is available by download and by direct access through an OPeNDAP/HTTP server. Additionally, we provide the code for performing the vortex-profile matching, along with an example of use to facilitate future updates to the code and merged data. This dataset supports further research on eddy vertical structure, biogeochemical processes, and their role in climate systems across different regions and time periods.
Interactive trajectory prediction for autonomous driving based on Transformer

Published: February 2025

Abstract. Trajectory planning has undergone remarkable strides in recent times, especially in the behavior prediction of traffic participants. Given that strong coupling conditions such as pedestrians, vehicles, and roads restrict the interactive behavior of autonomous vehicles and other traffic participants, it has become critical to design a trajectory prediction algorithm based on traffic scenarios for autonomous-driving technology. In this paper, we propose a novel trajectory prediction algorithm based on Transformer networks, a data-driven method that ingeniously harnesses dual-input channels. The rationale underlying this approach lies in its seamless fusion of scene context modeling and multi-modal prediction within a neural network architecture. At the heart of this innovative framework resides the multi-headed attention mechanism, ingeniously deployed in both the agent attention layer and the scene attention layer. This finessing not only captures the profound interdependence between agents and their surroundings but also imbues the algorithm with a better real-time predictive prowess, enhancing computational efficiency. Eventually, substantial experiments with the Argoverse dataset will demonstrate improved trajectory accuracy, with the minimum average displacement error (MADE) and minimum final displacement error (MFDE) being reduced by 12 % and 31 %, respectively.

Our study examines conspiracy theorists' perceptions of and misconceptions about content moderation practices on different social media platforms, as discussed in Telegram channels of the “Querdenken” community. Different narratives emerge in relation to the platforms discussed (Telegram, Facebook, and YouTube). Our findings provide insight into how conspiracy theorists construe disruptions in their communication channels, intertwining notions of platform power with their conspiratorial worldview.
IN THE SHADOW OF LLMS: TROUBLE IN THE “SMART” AUTOMOTIVE INDUSTRY
Authors: Gekker Alex , Hind Sam
Published: February 2025

This paper explores the tumultuous landscape of the modern automotive industry, once heralded as the epitome of artificial intelligence (AI) and machine learning (ML) applications through the promise of connected and autonomous vehicles (CAVs). The introduction of large language models (LLMs), notably with ChatGPT's launch in November 2022, marked a turning point, casting shadows over the ambitious goals set by major tech and automotive players. Notable failures, including Ford's shutdown of Argo AI and Volkswagen's struggle with electric vehicle transitions, have led to a crisis in the viability of connected and autonomous driving.

The paper identifies four central types of limitations contributing to this crisis: technical, economic, financial, and regulatory. Technical limitations expose the inadequacies of autonomous vehicles in meeting their promised capabilities. Economic limitations highlight the unsustainable nature of platformizing automotive operations, linked to innovations like vehicle subscription models. Financial limitations point to the speculative investment decisions that underpin technological projects. Regulatory limitations showcase the industry's renegotiation of conditions in response to safety concerns.

By examining these limitations, the paper establishes a conceptual framework applicable not only to the automotive industry but also to current discussions surrounding LLMs. The lessons drawn from these challenges contribute to a broader understanding of the perils and limitations within AI sub-industries.
THE BRAZILIAN DIGITAL BATTLEFIELD: INVESTIGATING THE DYNAMICS OF POLITICAL INFORMATION CAMPAIGNS IN POST-BOLSONARO ERA
Authors: Marino Giada , Almeida Paroni Bruna , Giglietto Fabio
Published: February 2025

The 2022 Brazilian presidential elections and subsequent events highlight a significant period of political polarization and misinformation, particularly on social media platforms like Facebook. This study investigates the dynamics of misinformation campaigns on Facebook in the context of Brazil's political shifts, focusing on the period from the 2022 elections to the aftermath of the attempted coup on January 8, 2023. Utilizing a mixed methods approach and an innovative news alert system, we analyzed three months of links shared in a coordinated fashion leading up to the first anniversary of the attempted coup.

Our findings reveal a bipartisan battlefield of political discourse, with a scenario characterized by divergence in accounts’ political alignment. We, in fact, identified two primary networks of political Facebook accounts: one supporting former President Jair Bolsonaro and another backing President Lula. Interestingly, we observed Lula supporters repeatedly share content criticizing or mocking Bolsonaro, his family members, and his supporters within pro-Bolsonaro groups. Moreover, these posts often receive a substantial number of comments and minor reactions and shares.

Future research will expand on these findings by examining a year's worth of Facebook posts from these networks to explore changes in topics and strategies over time.

The presentation will thus discuss the study's advancement outcomes in-depth, contributing to understanding how Brazilian political factions’ supporters utilize social media to influence public opinion and the implications for democracy in the digital age.

Lateral Internal Sphincterotomy for Fissure in Ano: A Retrospective Long-Term Review
Authors: Raj Rankeen , R Vishnuprasad
Published: February 2025

Anal fissure is a common benign disease which affects patient’s quality of life. Lateral internal sphincterotomy is a routine surgical treatment for it, but it has been reported to have long term recurrence and incontinence. Even though many studies are available in this subject, long term studies spanning over a decade is uncommon. In this case series analysis, the historical patient records of those who underwent lateral internal sphincterotomy in the last 10 years was analyzed, patients were contacted telephonically and information was recorded. A total of 306 patients were analyzed. In the post-op period 3.9% of patients had incontinence to flatus and 2% had incontinence to liquid feces which improved over 4-8 weeks. 8.8% of patients had recurrence. There were no wound related post op complications. None had long term incontinence. 88.6% were highly satisfied by the surgery. Female patients exhibited higher satisfaction (95.7%) and a lower recurrence rate (2.1%). Patients in the 18-30 age group demonstrated lower recurrence rates (4.5%) when compared to >60 years (50%). Recurrent episodes of constipation in the post-surgery period were strongly associated with a high fissure recurrence rate. Lateral internal sphincterotomy is a valuable surgery providing adequate pain relief, high healing rates, low complications, low recurrence rates and high patient satisfaction.

Key words: Anal fissure; Lateral internal sphincterotomy; Fecal Incontinence; Constipation.

Published: February 2025

Cancer is a major fatal disease worldwide, with millions of new cases and deaths each year. While treatments like chemotherapy and immunotherapy have saved many lives, they often come with severe side effects. A better solution being developed targeted drug delivery, which aims to deliver medication directly to cancer cells, which increasing the effectiveness of the treatment and reducing harmful side effects. One fascinating approach under development is sperm-loaded nanotherapy. This innovative method uses sperm cells as natural carriers for cancer drugs. Because sperm can move efficiently through the reproductive system, they’re ideal for targeting gynaecological cancers like cervical and ovarian tumors. By attaching anticancer drugs to sperm, researchers have created "spermbots" that navigate to tumors, deliver medication, and minimize harm to surrounding healthy tissues. This therapy takes advantage of nanotechnology to improve how drugs are delivered, including optimizing the size and shape of nanoparticles for better tumor penetration. While still experimental, this approach has shown promise in reducing cancer cell growth in lab studies. However, challenges like ensuring safety, improving drug loading efficiency, and addressing ethical concerns remain. Sperm-driven nanotherapy represents an exciting leap forward in cancer treatment, offering the potential for more precise, effective, and less toxic therapies. With further research, it could become a powerful tool not only for gynaecological cancers but also for other hard-to-reach tumors.

Key words: Cancer therapy, Nanotechnology, Targeted drug delivery, sperm-loaded nanotherapy, Enhanced permeability and retention (EPR), Spermbots.

Naar aanleiding van het eerder in dit Bulletin (1963, aflevering 1, blz. 11 e.v.) verschenen artikel over JanVermeyens Kardinaalsportret is Prof. J. Bruyn zo vriendelijk geweest mij attent te maken op een inventaris uit 1535, waarin de voorwerpen staan vermeld die Margaretha van Oostenrijk aan het Klooster van Brou had vermaakt. De volgende passage is van belang in verband met het schilderij van Vermeyen: ’Item ung double tableau dont l’un est Nostre Dame et l’autre le cardinal de Liegne, laquelle Nostre Dame a esté délivrée audit couvent de Broux et le cardinal demorre par dechà’ (Zie J. Duverger, De werken van ’’Johannes” in de verzameling van Margaretha van Oostenrijk, in Oud Holland 1928, blz. 214, noot 5). Hieruit blijkt dus dat beide panelen reeds vóór 1535 waren gescheiden.

Published: February 2025

Buffalo sperm suffer more cryoinjuries due to lipid peroxidation of their high structural polyunsaturated fatty acid contents than cattle. Consequently, the post-thaw fertilization potential of buffalo sperm is compromised. Crocin is a carotenoid known for its antioxidant potential through scavenging reactive oxygen species. The current study investigated the effect of crocin addition in the semen extender on the post-thaw quality, fertility- associated gene expression, and fertilization potential of buffalo bull sperm. Semen samples (n=32) from four Nili-Ravi buffalo bulls were extended with tris-citric acid extender containing different concentrations of crocin (0mM; control, 0.5, 1, 1.5, and 2mM). The extended semen was packed in 0.5 mL French straws (25 x 10 6 sperm/ straw) and cryopreserved using liquid nitrogen vapor freezing protocol. Computer-assisted semen analysis, Normal Apical Ridge assay, Rhodamine 123, Acridine orange, and Propidium iodide staining were used to assess sperm motility parameters, acrosome integrity, mitochondrial membrane potential, DNA integrity, and viability, respectively. Expression levels of sperm acrosome-associated SPACA3, DNA condensation-related PRM1, anti- apoptotic BCL2, pro-apoptotic BAX, and oxidative stress-associated ROMO1 genes were evaluated through qPCR. The in vivo fertility of semen doses containing 1mM crocin was compared with control. Buffaloes were inseminated 24 hours after the onset of natural estrus and transrectally palpated for pregnancy at least 60 days post-insemination. Data were analyzed through PROC MIXED or PROC GLIMMIX using SAS. Tukey test was applied for multiple comparisons among treatments. Post-thaw evaluation revealed that 0.5 and 1mM crocin improved total motility, plasma membrane integrity, acrosome integrity, mitochondrial membrane potential, and viability, and one and 1.5mM crocin enhanced catalase activity and reduced lipid peroxidation compared to control (p<0.05). Moreover, 1mM crocin improved progressive motility, kinematics, and DNA integrity than control (p<0.05). Expression levels of SPACA3, PRM1, and BCL2 genes were higher (p<0.05) with 1mM crocin, whereas no difference (p>0.05) was observed in the expression of BAX gene among all groups. Moreover, ROMO1 gene expression was higher (p<0.05) with 2mM compared to 1mM and 1.5mM crocin. Semen doses containing 1mM crocin showed a higher fertility rate compared to control [56±0.03% (112/200) vs. 46±0.04% (92/200), respectively; p=0.0465]. In conclusion, 1mM crocin addition in the semen extender improves post-thaw quality, fertility-associated gene expression, and fertilization potential of buffalo bull sperm.

The transfer of genome-modification components into farm animal cells is indispensable for the production of genome-modified and transgenic farm animals. Electroporation is a physical transfection method when appropriately used; this technique is safe, simple to use, affordable, and efficient in transfecting cells from several lineages. Electroporation efficiency depends on various physical parameters, of which cell type is considered a major factor for transfection efficiency. Primary cells are generally less susceptible to transfection than other cell types due to their finite lifespan and limited expansion capacity. Previously, we custom-designed a transfection buffer to deliver exogenous genetic components into mammalian cells. In the present study, we examined the effect of the developed buffer on transfection rates and cell viability of primary somatic cells from buffalo, cattle, goats, and sheep. To achieve the aims of this study, t primary somatic cells from skin biopsies were established and were transfected with a Venus-expression vector (pAcGFPs-Venus). We noticed that transfection rates of pAcGFPs-Venus were 22.51%, 17.56%, 22.81%, and 16.16% for buffalo, cattle, goats, and sheep cells, respectively. We also noticed that cell viability and proliferation rates were better in the case of goats, sheep, and cattle cells; also, these cells have less vacuolation than buffalo cells. In addition, we also generated MSTN (myostatin) KO (Knockout) cell clones from these cell populations, in which the efficiency of single-cell clone generation was high for goats and sheep cells. In conclusion, our lab-made transfection buffer can be efficiently used to generate genome-edited or transgenic farm animals for agriculture, biomedical, and veterinary applications.

Methods: 150 samples from people suffering from hepatitis B with chronic kidney disease, chronic kidney disease, and healthy people.
Result: showed a significant increase in urea, creatinine, albumin and glomerular filtration rate in the chronic HBV group and less in the CKD group. A significant increase in ALT, AST and ALP levels in the chronic renal failure group infected with HBV and CKD group.Regarding hemoglobin, white blood cells and platelets; it showed that there was a significant decrease in hemoglobin, platelets and white blood cells in chronic renal failure patients infected HBV and chronic renal failure patients.
Conclusion: In conclusion, clear evidence emerged from laboratory analyses of a clear relationship between infection with HBV and the degree of progression of chronic kidney disease. The results were statistically highly significant in people with CKD and viral hepatitis, more important than in people with CKD only.
From Berlin to Brady: Tracing the Origins of the Urology Residency
Authors: Hunt Trevor , Rabinowitz Ronald
Published: February 2025

Introduction

Urology was one of the first subspecialties in medicine to employ the training model known today as residency, yet no definitive account currently exists of how urology residency programs came into existence. These events are rarely taught in formal urologic curricula. It is imperative that tomorrow’s urologists understand how today’s system came to be.

Sources and Methods

We performed a comprehensive review of the literature, referencing primary and secondary sources including journal articles, books, textbook chapters, monographs, bulletins, editorials, and transcribed speeches, to compile sufficient evidence to complete this historical review.

Results

During the 13th-18th centuries, surgical training was undertaken in small and non-regulated apprenticeships. Napoleon created the first versions of the residency training model in early 1800s France. In Berlin, Bernhard von Langenbeck (1810-1887) devised the most direct early predecessor of the modern system. An early trainee, Theodor Billroth (1829-1894) later mentored American surgeon William Halsted (1852-1922) and passed along the training methods. At Johns Hopkins Hospital, Halsted drew on Billroth’s methods to establish the “pyramidal” training model in 1890. This was later adapted by Edward Churchill (1895-1972) at Massachusetts General Hospital into the “rectangular” structure in the 1930s, which is closer to existing residency programs today. Hugh Hampton Young (1879-1944), the ‘Father of American Urology’, was hired by Halsted at Hopkins and quickly became Chair of the Department of Genitourinary Diseases in 1897. Young informally recommended aspiring urologists to Halsted for appointment in the surgical residency, spawning the beginnings of the urologic specialty. In 1915, the Brady Urological Institute opened at Hopkins via a donation from Young’s patient James Buchanan Brady (1856-1917), and a 7-year training program was designed alongside it. With this, the first formal urology residency in the country was born.

Conclusions

American urology residency formally began in 1915 at Johns Hopkins Hospital under the direction of Hugh Hampton Young and shares deep roots with the history of surgery itself. Recognizing where this training model originated is a critical context for all who seek to improve how the urologists of tomorrow are trained.
捷泳划手技巧之重要因素探討

游泳中的捷式，俗稱自由式，是游泳比賽四個泳姿中速度最快的，也是比賽項目最多的一種泳姿，選手除了要保持流線型泳姿以減少阻力外，還須注意划手動作以增加推進力。本文的目的在探究捷泳划手動作的相關文獻，藉此了解影響整個划手動作的重要因素。經由相關文獻的統整可得到以下三個划手時的重點：一、水中划手動作有二次的加速，分別在內划和上划階段。內划階段主要是靠肩的關節轉動，而上划階段主要是靠肩和肘的關節轉動，來增進推水速度；二、划手動作和身體的滾動需互相配合，如此不但可使前進的阻力較小，也可同時增加划手向後推時加速的一致性；三、多數的研究結果指出在推水時手指微微張開會比完全併攏可產生較大的推進力量。在許多捷泳划手相關的實驗性研究中，尚未看到有針對水中動作的划手深度、手肘彎曲程度或加速策略的相關技巧探討，這些課題也許可作為進一步研究的思考方向。

 

The front crawl stroke, or freestyle, is the fastest stroke, and has most events of four swimming competitive styles. Swimmers not only have to keep a streamlined form to decrease the drag but also to focus on the skills of armstroke to increase the propulsive force in front crawl stroke. So, the purpose of this article was to find out several important factors that swimmers should focus on when executing front crawl armstroke from previous studies. There were three key points in the processing of total armstroke: 1. Swimmers accelerated the hand twice to push the water, one was in insweep phase, another was in upsweep phase. The shoulder rotation was the main contributor to the stroke velocity in insweep phase. The shoulder and elbow rotation were the main contributors to the stroke velocity in upsweep phase. 2. The movement of armstroke in the water should work in coordination with body rolling, it was not only decreasing the resistance but also having the timing consistent with the acceleration of hands. 3. Most studies indicated that a small finger spread leads to increase propulsive forces but not total grouped in the water. Many experimental studies related to armstroke of front crawl, were not focus on stroke depth, elbow flexion condition, or strategies of hand acceleration. These may provide some thinking direction about further studies.

The corrosion resistance effect of malic acid for aluminium steel immersed in sodium chloride solution has been evaluated at room temperature by using weight loss method. The corrosion inhibition efficiency increases with increase in concentration of an inhibitor namely malic acid. The corrosion rate decreases when increase in concentration of inhibitor. This is due to at the higher concentration of inhibitor solution which prevents the active site of an aluminium steel and a protective film is formed over the aluminium steel surface. The mechanistic aspect of corrosion inhibition by electrochemical studies, such as polarization studies and AC- impedance spectra. The protective film is formed over the aluminium steel has been characterized by FTIR. It is also recognized by surface analysis technique like scanning electron microscopy. Smoothness and roughness of aluminium steel surface like polished, corroded and inhibitor system has been assessed by SEM.
