Uncontrolled regeneration leads to neoplastic transformation1–3. The intestinal epithelium requires precise regulation during continuous homeostatic and damage-induced tissue renewal to prevent neoplastic transformation, suggesting that pathways unlinking tumour growth from regenerative processes must exist. Here, by mining RNA-sequencing datasets from two intestinal damage models4,5 and using pharmacological, transcriptomics and genetic tools, we identified liver X receptor (LXR) pathway activation as a tissue adaptation to damage that reciprocally regulates intestinal regeneration and tumorigenesis. Using single-cell RNA sequencing, intestinal organoids, and gain- and loss-of-function experiments, we demonstrate that LXR activation in intestinal epithelial cells induces amphiregulin (Areg), enhancing regenerative responses. This response is coordinated by the LXR-ligand-producing enzyme CYP27A1, which was upregulated in damaged intestinal crypt niches. Deletion of Cyp27a1 impaired intestinal regeneration, which was rescued by exogenous LXR agonists. Notably, in tumour models, Cyp27a1 deficiency led to increased tumour growth, whereas LXR activation elicited anti-tumour responses dependent on adaptive immunity. Consistently, human colorectal cancer specimens exhibited reduced levels of CYP27A1, LXR target genes, and B and CD8 T cell gene signatures. We therefore identify an epithelial adaptation mechanism to damage, whereby LXR functions as a rheostat, promoting tissue repair while limiting tumorigenesis.

Authors: Apeltauer Tomáš , Uhlík Ondřej , Apeltauer Jiří , Juřík Vojtěch
Published: November 2024

Understanding pedestrian movement remains crucial for designing efficient and safe transportation structures such as terminals, stations, or airports. The significance of conducting a granular analysis in pedestrian mobility dynamics research is evident in refining crowd behavior modeling. It is essential for gaining insights into potential terminal layouts, crowd management strategies, and evacuation procedures, all of which enhance safety and efficiency. In this context, we offer an original empirical dataset of 24,000,000 samples of trajectory spatial movement at traffic terminals in Havlíčkův Brod and Pardubice, Czech Republic. The dataset was collected using a high-resolution camera system installed at the railway station. Subsequently, algorithmic post-processing was applied to extract anonymous data on the spatial movement of recorded pedestrians. Thanks to this dataset, researchers can delve into the distances between pedestrians in a transportation terminal, considering factors such as group composition, group-to-group distances, and movement speed.
A continuous pursuit dataset for online deep learning-based EEG brain-computer interface
Authors: Forenzo Dylan , Zhu Hao , He Bin
Published: November 2024

This dataset is from an EEG brain-computer interface (BCI) study investigating the use of deep learning (DL) for online continuous pursuit (CP) BCI. In this task, subjects use Motor Imagery (MI) to control a cursor to follow a randomly moving target, instead of a single stationary target used in other traditional BCI tasks. DL methods have recently achieved promising performance in traditional BCI tasks, but most studies investigate offline data analysis using DL algorithms. This dataset consists of ~168 hours of EEG recordings from complex CP BCI experiments, collected from 28 unique human subjects over multiple sessions each, with an online DL-based decoder. The large amount of subject specific data from multiple sessions may be useful for developing new BCI decoders, especially DL methods that require large amounts of training data. By providing this dataset to the public, we hope to help facilitate the development of new or improved BCI decoding algorithms for the complex CP paradigm for continuous object control, bringing EEG-based BCIs closer to real-world applications.

Published: November 2024

Marine heatwaves have profoundly impacted marine ecosystems over large areas of the world oceans, calling for improved understanding of their dynamics and predictability. Here, we critically review the recent substantial advances in this active area of research, including the exploration of the three-dimensional structure and evolution of these extremes, their drivers, their connection with other extremes in the ocean and over land, future projections, and assessment of their predictability and current prediction skill. To make progress on predicting and projecting marine heatwaves and their impacts, a more complete mechanistic understanding of these extremes over the full ocean depth and at the relevant spatial and temporal scales is needed, together with models that can realistically capture the leading mechanisms at those scales. Sustained observing systems, as well as measuring platforms that can be rapidly deployed, are essential to achieve comprehensive event characterizations while also chronicling the evolving nature of these extremes and their impacts in our changing climate.
The molybdenum cycle in the oxygenated Neoproterozoic ocean was coupled to manganese carbonate mineralization
Authors: Zhang Bin , Cao Jian , Hu Kai , Liao Zhiwei , Zhang Ruijie , Zhang Yi , Shi Chunhua , Konhauser Kurt O.
Published: November 2024

The Neoproterozoic oxygenation event is a milestone in Earth’s history, yet the redox structure and elemental cycling of the Neoproterozoic ocean remain debated. Here, we investigated iron speciation, molybdenum, and nitrogen isotopes in black shales and manganese carbonates from the upper Ediacaran Doushantuo Formation, South China, to examine the links between redox state, manganese mineralization, and molybdenum cycling. In both lithologies, high pyritic iron ratios (> 0.8) indicate a localized euxinic zone, while estimated seawater molybdenum (1.9‰) and sediment nitrogen isotopic compositions (4.19 ± 1.96‰) resemble modern values, suggesting oxygenated surface waters over euxinic depths. Negative molybdenum isotope in manganese(II) carbonates points to manganese(IV) oxide reduction, acting as a molybdenum shuttle from oxygenated surface to euxinic deep waters. Periodic euxinic contractions drove manganese(II) oxidation and mineralization, shaping molybdenum cycling. This study highlights essential manganese(II) oxidation for manganese carbonate mineralization and offers new insights into molybdenum geochemistry and ancient ocean oxygenation events.

Cardiac trabeculae form a network of muscular strands that line the inner surfaces of the heart. Their development depends on multiscale morphogenetic processes and, while highly conserved across vertebrate evolution, their role in the pathophysiology of the mature heart is not fully understood. Here we report variant associations across the allele frequency spectrum for trabecular morphology in 47,803 participants of the UK Biobank using fractal dimension analysis of cardiac imaging. We identified an association between trabeculation and rare variants in 56 genes that regulate myocardial contractility and ventricular development. Genome-wide association studies identified 68 loci in pathways that regulate sarcomeric function, differentiation of the conduction system and cell fate determination. We found that trabeculation-associated variants were modifiers of cardiomyopathy phenotypes with opposing effects in hypertrophic and dilated cardiomyopathy. Together, these data provide insights into mechanisms that regulate trabecular development and plasticity, and identify a potential role in modifying monogenic disease expression.
Towards an IPCC Atlas for comprehensive climate change risk assessments
Authors: Alegría Andrés , Poloczanska Elvira , Loeschke Sina , Mintenbeck Katja , Poertner Hans
Published: November 2024

Climate risk assessments are crucial in quantifying and communicating risks in a clear and concise manner. In light of the rapidly proceeding climatic changes, there is a growing need for a more comprehensive integration and a more effective overview of available and relevant data that go into these assessments, particularly on the temporal and spatial dynamics of risk. In this paper, we describe the advantages, challenges and opportunities for increasing the accessibility of temporal and spatial data needed to support climate risk assessments through the development of an Intergovernmental Panel on Climate Change (IPCC) Atlas, integrated across IPCC Working Groups. We propose that using a climate risk framework to organise this Atlas will result in a more practical resource for understanding and informing risk assessments undertaken by the IPCC, and also make methodologies and results more accessible to a wider audience.

Myogenesis is essential for skeletal muscle formation and regeneration after injury, yet its regulators are largely unknown. Here we identified fibronectin type III domain containing 1 (FNDC1) as a previously uncharacterized myokine. In vitro studies showed that knockdown of Fndc1 in myoblasts reduces myotube formation, while overexpression of Fndc1 promotes myogenic differentiation. We further generated recombinant truncated mouse FNDC1 (mFNDC1), which retains reliable activity in promoting myoblast differentiation in vitro. Gain- and loss-of-function studies collectively showed that FNDC1 promotes cardiotoxin (CTX)-induced muscle regeneration in adult mice. Furthermore, recombinant FNDC1 treatment ameliorated pathological muscle phenotypes in the mdx mouse model of Duchenne muscular dystrophy. Mechanistically, FNDC1 bound to the integrin α5β1 and activated the downstream FAK/PI3K/AKT/mTOR pathway to promote myogenic differentiation. Pharmacological inhibition of integrin α5β1 or of the downstream FAK/PI3K/AKT/mTOR pathway abolished the pro-myogenic effect of FNDC1. Collectively, these results suggested that myokine FNDC1 might be used as a therapeutic agent to regulate myogenic differentiation and muscle regeneration for the treatment of acute and chronic muscle disease.

Published: November 2024

Tissue homeostasis and regeneration involve complex cellular changes. The role of rRNA modification-dependent translational regulation in these processes remains largely unknown. Planarians, renowned for their ability to undergo remarkable tissue regeneration, provide an ideal model for the analysis of differential rRNA regulation in diverse cell types during tissue homeostasis and regeneration. We investigated the role of RNA 2’-O-methyltransferase, Fibrillarin (FBL), in the planarian Schmidtea mediterranea and identified two FBL homologs: Smed-fbl-1 (fbl-1) and Smed-fbl-2 (fbl-2). Both are essential for planarian regeneration, but play distinct roles: fbl-1 is crucial for progenitor cell differentiation, while fbl-2 is important for late-stage epidermal lineage specification. Different 2’-O-methylation patterns were observed upon fbl-1 and fbl-2 knockdown, suggesting their roles in translation of specific mRNA pools during regeneration. Ribo-seq analysis further revealed differing impacts of fbl-1 and fbl-2 knockdown on gene translation. These findings indicate divergent roles of the duplicate fbl genes in specific cell lineage development in planarians and suggest a role of rRNA modifications in translational regulation during tissue maintenance and regeneration.
Optical Spectroscopy
Authors: Kaizaki Sumio
Published: November 2024

This chapter describes optical spectroscopy of coordination compounds including the electronic transitions underpinning absorption spectra and chiroptical spectra. For the spin-allowed and spin-forbidden ligand field d–d absorption spectra, dependence of the number of d electrons, ligands and geometrical structures are discussed together with the band intensities and selection rules in terms of the ligand field theory and the Angular Overlap Model on the basis of the background in Chapter 1. Electronic transitions other than ligand field transitions such as intraligand transitions, charge transfer transitions, mixed valence complexes, metal–metal bond and 4f–4f transitions are explained. In combination with electronic transitions, chiroptical spectra deal with circular dichroism (CD), magnetic circular dichroism (MCD), circularly polarized luminescence (CPL) and the cross effects between CD and MCD.

Despite extensive research, strategies to effectively combat breast cancer stemness and achieve a definitive cure remains elusive. CD44, a well-defined cancer stem cell (CSC) marker is reported to promote breast cancer tumorigenesis, metastasis, and chemoresistance. However, mechanisms leading to its enhanced expression and function is poorly understood. Here, we demonstrate that USP10 positively regulates CD44 protein levels and its downstream actions. While USP10 depletion prominently down-regulates CD44 protein levels and functions, its overexpression significantly enhances CD44 protein levels, leading to enhanced cluster tumor cell formation, stemness, and metastasis in breast cancer cells both in vitro and ex vivo in primary human breast tumor cells. USP10 interacts with CD44 and stabilizes it through deubiquitination both in breast cancer cell lines and human breast cancer-derived primary tumor cells. Stabilized CD44 shows enhanced interaction with cytoskeleton proteins Ezrin/Radixin/Moesin and potently activates PDGFRβ/STAT3 signaling which are involved in promoting CSC traits. Using USP10 stably expressing 4T1 cells, we further demonstrate that the USP10-CD44 axis potently promotes tumorigenicity in vivo in mice, while simultaneous depletion of CD44 in these cells renders them ineffective. In line with these findings, we further showed that inhibition of USP10 either through RNAi or the pharmacological inhibitor Spautin-1 significantly mitigated CD44 levels and its downstream function ex vivo in primary breast tumor cells. Finally, we demonstrated that primary breast tumor cells are more susceptible to chemotherapy when co-treated with USP10 inhibitor indicating that the USP10-CD44 axis could be an attractive therapeutic target in combination with chemotherapy in CD44 expressing breast cancers.
General numerical solution of integral equation for long‐range low‐frequency groundwave propagation over irregular terrain
Authors: Wang Dan‐Dan , Lu Qi‐Zirui , Han Chao , Fang Yun , Pu Yu‐Rong
Published: November 2024

The flexibility of the integral equation (IE) method is limited by the available numerical solutions with uniform‐grid schemes. In this paper, a general numerical solution of the IE is presented to predict long‐range low‐frequency (LF) groundwave propagation over irregular terrain. The general numerical solution is re‐derived with the aid of Legendre–Gauss quadrature and interpolation quadrature. The great advantage of the resulting algorithm is that it can freely use non‐uniform grid sizes in the computation area without loss of accuracy. Numerical results in two surface types, including triangular mountain and actual terrain are used to demonstrate the performance of the presented algorithm. Furthermore, it is ascertained that the non‐physical perturbations at long propagation ranges in the IE predictions are caused by the inherent uniform‐grid schemes of the numerical solution rather than the several approximations in the derivation of the IE form.

We identify three dominant evolutionary tracks to form neutron star binaries that merge within the age of the Universe: a scenario that includes a common envelope phase between the first neutron star and its companion, a scenario with almost equal-mass progenitors that evolve quasi-simultaneously and feature a double-core common envelope, and a scenario involving the accretion-induced collapse of an oxygen-neon white dwarf into a neutron star. We show that the distribution of time delays between stellar formation and binary neutron star merger at a given progenitor metallicity does not follow a power law but instead features a complex structure that reflects the progenitor properties and the relative contribution of each evolutionary track. We also explore the evolution of the merger rate density with redshift, and we show that the scenario involving the accretion-induced collapse could be dominant at high redshifts. These results can have important implications for the study of the chemical enrichment of galaxies in r-process elements produced in kilonovae and of short gamma-ray burst offsets in their host galaxies.
Theoretical and experimental studies about single cane reeds: a review
Authors: Gaillard Amélie , Koehl Vincent , Gazengel Bruno
Published: November 2024

Since the late 19th century, researchers have measured and predicted the acoustic properties of single-reed instruments like the clarinet and saxophone. According to musicians, the reed itself has a significant impact on sound production and playing comfort. However, the physics of the reed remains incompletely understood, and reed makers are constantly seeking a deeper comprehension that could allow them to deduce physical parameters that more adequately account for the sensations of musicians. This is the reason why some researchers are interested in studying the behavior of reeds, either through the creation of physical models or through physical or perceptual experiments. The present paper proposes a review of these studies, structured into three sections. Firstly, the physics of single-reeds and single-reed instruments is exposed and described by various models of increasing complexity. The experimental studies about single cane reeds are then detailed in the second and third sections, which respectively deal with perceptual assessments and physical measurements. Finally, the conclusion synthesizes and brings together the findings from each section to provide a comprehensive overview of current knowledge while also highlighting prospects for future research.

Published: November 2024

The study meticulously investigates the irradiation phenomenon of the widely prevalent silicon-28 isotopes by low-energy cosmic protons, highlighting the implications of such interactions. In our analysis, we explore conditions characterized by low empirical currents, ensuring low energy consumption while maintaining relatively high monochromaticity in the incident proton beam. A significant focus is placed on the Rutherford scattering probability, which serves as a fundamental aspect in understanding the nuances of nuclear reactions that emerge from these interactions. As we delve deeper into our findings, we examine the decay chains of the resultant radioactive nuclei produced during the irradiation process. This involves identifying individual decay pathways, detailing the formation of corresponding radioactive nuclei, and investigating the annihilation of positrons released during these nuclear reactions. Alongside, we present precise measurements of outgoing currents and energy values, offering a comprehensive overview that contributes to the broader field of cosmic radiation effects on terrestrial isotopes.

This work is dedicated to investigating the thermo-optical effects in a nonlinear ZnGeP2 crystal during parametric generation. The stable regime of the laser resonator was determined. It was found that for a resonator length of 43 mm, a stable regime was observed for all focal lengths of the thermal lens induced in the crystal. However, increasing the resonator length to 183 mm, the stability zone of the cavity no longer extends to the entire range of focal lengths of the induced thermal lens. Thus, the resonator becomes unstable for focal lengths of the induced thermal lens f ≤ 150 mm, which leads to high intracavity losses and is an undesirable operating mode of the cavity. Therefore, the experimental work has shown that when creating systems based on parametric generators with ZnGeP2 crystals, it is essential to consider the effect of the induced thermal lens and perform calculations of the cavity stability.

Authors: Al-Rufaee F. M. , Yakimovich B. A. , Kuvshinov V. V.
Published: November 2024

This paper presents the results of experimental analysis of piezoelectric-based power conversion circuits under vibration. Three types of circuits were evaluated: a standard full bridge rectifier (S-FBR) circuit, a self power synchronous electrical charge extraction circuit (SECE-sp), and an optimized self power synchronous charge extraction circuit (SECEopt-sp). Experiments were conducted to evaluate the effectiveness of energy conversion under real operating conditions. The results showed that the SECEopt-sp scheme has the highest energy conversion effectiveness and stable output power, outperforming other tested schemes. The optimum operating parameters of the circuit are identified to ensure minimum energy loss and maximum output power. SECEopt-sp provides maximum output power and stability under varying load conditions. Thus, SECEopt-sp was found to be the most efficient circuit for harvesting energy from low-frequency mechanical vibrations such as water motion or waves.

Comparative study of heat transfer in apparatuses with turbine and blade agitators
Authors: Ponikarov Sergey , Salin Alexey
Published: November 2024

In the framework of this research, modeling of flows and heat transfer in apparatuses with turbine and blade agitators using the ANSYS CFX software package has been carried out. The purpose of the work is to create digital prototypes of apparatuses with stirring devices to improve the effectiveness of technological processes of various chemical and petrochemical industries. Modeling was carried out on the basis of three different objectives, including the processes of water heating and mixture of water with glycerol. In each objective, the heating and circulation characteristics of the liquid during mixing using turbine and blade agitators were investigated. The effects of parameters such as apparatus wall temperature, water and mixture flow rate, rotation speed and agitator type on the time characteristics of reaching steady-state were evaluated. The simulation results demonstrated that turbine and blade agitators provide more efficient mixing and heating of the liquid compared to blade agitators, all other conditions being equal. Fluid temperatures reached higher values in a shorter time when turbine agitators were used, making them preferable for processes where intensive mixing and rapid heating are required. This approach can be useful to optimize mixing processes on production lines and improve the energy efficiency of production facilities.
