Mechanisms and pathologies of human mitochondrial DNA replication and deletion formation
Authors: Bernardino Gomes Tiago M. , Vincent Amy E. , Menger Katja E. , Stewart James B. , Nicholls Thomas J.
Published: May 2024

Human mitochondria possess a multi-copy circular genome, mitochondrial DNA (mtDNA), that is essential for cellular energy metabolism. The number of copies of mtDNA per cell, and their integrity, are maintained by nuclear-encoded mtDNA replication and repair machineries. Aberrant mtDNA replication and mtDNA breakage are believed to cause deletions within mtDNA. The genomic location and breakpoint sequences of these deletions show similar patterns across various inherited and acquired diseases, and are also observed during normal ageing, suggesting a common mechanism of deletion formation. However, an ongoing debate over the mechanism by which mtDNA replicates has made it difficult to develop clear and testable models for how mtDNA rearrangements arise and propagate at a molecular and cellular level. These deletions may impair energy metabolism if present in a high proportion of the mtDNA copies within the cell, and can be seen in primary mitochondrial diseases, either in sporadic cases or caused by autosomal variants in nuclear-encoded mtDNA maintenance genes. These mitochondrial diseases have diverse genetic causes and multiple modes of inheritance, and show notoriously broad clinical heterogeneity with complex tissue specificities, which further makes establishing genotype-phenotype relationships challenging. In this review, we aim to cover our current understanding of how the human mitochondrial genome is replicated, the mechanisms by which mtDNA replication and repair can lead to mtDNA instability in the form of large-scale rearrangements, how rearranged mtDNAs subsequently accumulate within cells, and the pathological consequences when this occurs.
X-ray variability of the triplet star system LTT1445 and evaporation history of the planets around its A component

Published: May 2024

Context. The high-energy environments of host stars could prove deleterious for their planets. It is crucial to ascertain this contextual information to characterize the atmospheres of terrestrial exoplanets.

Aims. We aim to fully characterize a unique triple system, LTT1445, with three known rocky planets around LTT 1445A.

Methods. We studied the X-ray irradiation and flaring of this system based on a new 50 ks Chandra observation, which is divided into 10 ks, 10 ks, and 30 ks segments conducted two days apart, and two months apart, respectively. These data were complemented by an archival Chandra observation approximately 1 yr earlier and repeated observations with extended ROentgen Survey with an Imaging Telescope Array (eROSITA), the soft X-ray instrument on the Spectrum-Roentgen-Gamma (SRG) mission. This enabled the investigation of X-ray flux behavior across multiple time scales. With the observed X-ray flux from the exoplanet host star A, we estimated the photo-evaporation mass loss of each exoplanet. With the planet modeling package, VPLanet, we predicted the evolution and anticipated current atmospheric conditions.

Results. Our Chandra observations indicate that LTT 1445C is the dominant X-ray source, with additional contribution from LTT 1445B. We find that LTT 1445A, a slowly rotating star, exhibits no significant flare activity in the new Chandra dataset. Comparing the flux incident occuring on the exoplanets, we find that LTT 1445BC components do not pose a greater threat to the planets orbiting LTT 1445A than the emission from A itself. According to the results from the simulation, LTT 1445Ad could have the capacity to retain its water surface.

Published: May 2024

The large-scale mass distributions of galaxy-scale strong lenses have long been assumed to be well described by a singular ellipsoidal power-law density profile with external shear. However, the inflexibility of this model could lead to systematic errors in astrophysical parameters inferred with gravitational lensing observables. Here, we present observations with the Atacama Large (sub-)Millimetre Array (ALMA) of three strongly lensed dusty star-forming galaxies at ≃30 mas angular resolution and investigate the sensitivity of these data to angular structure in the lensing galaxies. We jointly infer the lensing mass distribution and the full surface brightness of the lensed sources with multipole expansions of the power-law density profile up to the fourth order using a technique developed for interferometric data. All three datasets strongly favour third and fourth-order multipole amplitudes of ≈1 percent of the convergence. While the infrared stellar isophotes and isodensity shapes agree for one lens system, for the other two the isophotes disagree to varying extents, suggesting contributions to the angular structure from dark matter intrinsic or extrinsic to the lensing galaxy.
The time-variable ultraviolet sky: Active galactic nuclei, stars, and white dwarfs
Authors: Bühler R. , Schliwinski J.
Published: May 2024

Here, we present the first catalog of Ultraviolet time-VAriable sources (1UVA). We describe a new analysis pipeline called VAriable Source Clustering Analysis (VASCA). We applied this pipeline to 10 yr of data from the Galaxy Evolution Explorer (GALEX) satellite. We analyzed a sky area 302 deg2, and detected 4,202 time-variable ultraviolet (UV) sources. We cross-correlated these sources with multi-frequency data from the Gaia satellite and the Set of Identifications, Measurements and Bibliography for Astronomical Data (SIMBAD) database, finding an association for 3,655 sources. The source sample was dominated by active galactic nuclei (≈73%) and stars (≈24%). We examined the UV and multi-frequency properties of these sources, focusing on the stellar population. We found UV variability for four white dwarfs (WDs). One of them, WD J004917.14–252556.81, was recently found to be the most massive pulsating WD. Its spectral energy distribution shows no sign of a stellar companion. The observed flux variability was unexpected and difficult to explain.

We report on the detection of X-ray polarisation in the black-hole X-ray binary Swift J1727.8−1613 during its dim hard spectral state by the Imaging X-ray Polarimetry Explorer (IXPE). This is the first detection of X-ray polarisation at the transition from the soft to the hard state in an X-ray binary. We find an averaged 2–8 keV polarisation degree of (3.3 ± 0.4)% and a corresponding polarisation angle of 3° ±4°, which matches the polarisation detected during the rising stage of the outburst, in September–October 2023, within 1σ uncertainty. The observational campaign complements previous studies of this source and enables comparison of the X-ray polarisation properties of a single transient across the X-ray hardness-intensity diagram. The complete recovery of the X-ray polarisation properties, including the energy dependence, came after a dramatic drop in the X-ray polarisation during the soft state. The new IXPE observations in the dim hard state at the reverse transition indicate that the accretion properties, including the geometry of the corona, appear to be strikingly similar to the bright hard state during the outburst rise despite the X-ray luminosities differing by two orders of magnitude.

Published: May 2024

Aiming at the extraction and recovery of rare earth elements (REEs) in low-concentration rare earth leaching tailings, a kind of phosphorylated conjugated microporous organic polymer (P-CMP) was prepared and applied to adsorb rare earth ions (Nd3+, Dy3+, Y3+). The structure of P-CMP was characterized by FT-IR. SEM and EDS were utilized to illustrate the surface morphology and element distribution of P-CMP, respectively.The adsorption mechanism of P-CMP was determined by XPS. The effects of pH, ion concentration and adsorption time on adsorption capacity were investigated. The isotherm of the rare earth adsorption process was fitted by Langmuir and Freundlich models, and the kinetics was fitted by Pseudo-firstorder and Pseudo-second-order. The results show that P-CMP is an amorphous microporous material, which has strong interaction with Nd3+ (30.18 mg/g), Dy3+ (37.84 mg/g) and Y3+ (22.01 mg/g), and the synergistic effect of amino and phosphate groups provides good selectivity (S.F.(Nd3+/Men+) = 5*103~5*104). The PCMP selectively adsorbs rare earth ions in the actual system and cycles 8 times.

Published: May 2024

In China, tight sandstone gas reservoirs are widely distributed, yet their development is hindered by issues such as low extraction efficiency and a monotonous extraction approach. To enhance the efficiency of tight sandstone gas extraction, this study investigates the internal fracture network characteristics of sandstone and its correlation with chemical solutions. Employing the sandstone acid fracturing technique, an experimental setup under gravitational conditions is established. Through this apparatus, fracturing experiments are primarily conducted on rocks utilizing the acid fracturing technique. The experimental findings suggest that the acid-fracturing coupling approach effectively induces rock fracturing. Uniaxial compression tests also indicate a noticeable alteration in the elastic-plastic behavior of rock samples after chemical solution corrosion, becoming more pronounced with increasing duration. The research demonstrates that this experimental setup significantly enhances the fracturing of sandstone and consequently improves the extraction of tight sandstone gas, holding crucial reference value.

Sensitivity analysis of underwater launch based on Morris method
Authors: Xie Jian , Cheng Dong , Chang Shuli , Li Pengtao
Published: May 2024

The discharge velocity, pressure difference and acceleration of underwater launch performance are affected by many factors, including depth, sailing speed, burning rate, water temperature, density and other operating parameters. The existing underwater launch sensitivity analysis is a local sensitivity qualitative analysis based on single-step perturbation analysis, which can only investigate the influence of a single uncertain factor on the model results in a small range. In this paper, based on the underwater launch model under multi-factor coupling, 10 input parameters were selected to calculate the multi-factor sensitivity of the underwater launch model based on the three objectives of velocity, pressure difference and acceleration at the time of discharge, and the Morris global sensitivity analysis method was used to calculate the sensitivity of the underwater launch model, and the sensitivity of the 10 input parameters to the model results was sorted. The results show that the five input parameters of burning rate, depth, propellant temperature, density and water temperature have the highest sensitivity to velocity, pressure difference and acceleration, and the sensitivity order is slightly different. The influence of water temperature on the three targets is almost evenly distributed in the range of values, and the other parameters have different sensitive ranges for different targets.

Published: May 2024

In the current environment of China's vigorous development of energy storage, it is essential to carry out research on the benefits and economic evaluation of new energy storage. This paper establishes a framework for analyzing the revenue models of various types of energy storage under different scenarios. The framework complements the lack of previous studies on energy storage regulation under power generation systems such as wind power and coal power. In addition, a variety of scenarios were developed for the application of energy storage in the spot market, secondary service market, capacity market and user-side trading market. The results show that the case study energy storage plant has the highest revenue in the spot market, followed by the capacity market, and relatively low revenue in the secondary service market, while the leasing service can also bring a lot of revenue for the energy storage plant and thus become one of the more promising energy storage revenue models in the future.
How do the construction of urban high-speed railways influence green total factor energy efficiency?
Authors: Yu Ting
Published: May 2024

As a typical measure for reducing carbon footprint, the opening of high-speed railways (HSRs) is a powerful lever for attaining the strategic purpose of carbon peak and carbon neutrality. Derived from the data of 265 prefecture-level cities in China from 2001 to 2018, this study adopts the Dynamic Network Slacks-Based Measure (DNSBM) model and introduces link variables and carry-over variables to conduct a dynamic assessment of green total factor energy efficiency (GTFEE). The study finds that the opening of HSRs significantly improved the GTFEE and this conclusion is robust under multiple conditions such as PSM-DID, counterfactual test and exclusion of other policy interference. Heterogeneity analysis indicates that the construction of HSRs has a more significant positive influence on GTFEE in smart city pilot cities, non-old industrial base cities middle and lower reaches of the Yangtze River Economic Belt (YREB). Mechanism testing indicates that economy concentration effect, structural optimization effect, and innovation driven effects are the transmission channels of HSRs in promoting low-carbon transition.

Published: May 2024

Based on the data of 84 listed oil and gas companies in China from 2012 to 2021, we empirically analyzed the impact of the digital transformation level of China's oil and gas companies on the level of carbon emissions through fixed panel model and mediation effect model.The results of the study show that the development of digital transformation significantly reduces the carbon emissions of oil and gas enterprises, and that digital transformation reduces the carbon emissions of enterprises mainly by being able to influence the optimization of enterprise structure and accelerate technological innovation. There is a moderating effect in the influence of digital transformation and carbon emissions for oil and gas enterprises. These conclusions hold after robustness tests and consideration of endogeneity issues.

Published: May 2024

Nowadays, energy and environmental problems are becoming more and more prominent, and the energy-based manufacturing industry also needs to face huge energy consumption problems. Therefore, production processes need to be investigated from an energy efficiency perspective at an early design stage so that maximum benefits can be obtained at low cost, low time and low risk. This process industry carbon emissions system does not calculate the consumption of raw materials and electricity in a generalized way at the boundaries of the plant. Rather, we delve into each step of the process and perform mathematical modeling of the process through a graphical approach, incorporating each link and factor that constitutes and influences the change in carbon emissions, and performing an aggregation of carbon emissions for the entire production line. It facilitates the subsequent improvement and optimization of the entire process-based production line, providing the basis for implementing and establishing the best energy-saving system.

Published: May 2024

Campaigns are employed as a fairly practical tactic to address an extensive audience in order to improve driving behaviour and promote road safety. Experts in the field of traffic safety concur that the most effective campaigns for improving traffic safety are those that draw from psychosocial theories of behaviour. The main objective of this article is to review the behavioural change theories related to various types of road safety initiatives. This study examines the body of prior research that, taken as a whole, eliminates the ability to draw accurate and thorough conclusions on the efficacy of behaviour-change theory-based campaigns. The road safety campaigns that embraced behaviour change theories may aid in changing drivers’ behaviour as well as the factors that influence it, such as their knowledge, attitudes, beliefs, emotions, motivations, abilities, habits, and environmental cues, as demonstrated by the campaigns that these studies reviewed. This study offered proof in support of the practicality of directing traffic safety measures through behaviour modification theories.

Published: May 2024

Nickel oxide (NiO) is one of the p-type semiconductors with unique properties suitable for nanosensor applications. It has a wide range band gap and can be fabricated in various methods, leading to different nanostructures and results. In this study, undoped and lithium (Li)-doped NiO were fabricated using the immersion method to investigate their properties. The field emission scanning electron microscopy analysis revealed that both samples produced two layers of nanosheet and nano coral reef-like (CR) structures. X-ray diffraction patterns confirmed the average crystallite sizes for undoped and Li-doped NiO are 24.70 nm and 31.19 nm, respectively. According to ultraviolet-visible spectroscopy, Li-doped NiO has a higher average transmittance percentage of 53% compared to undoped NiO, which has 40%. The estimated optical band gap values are not much different, with 3.94 eV for undoped and 3.95 eV for Li-doped. Electrical measurements also indicated that Li-doped NiO has a higher conductivity value of 7.9 x 10-2 S.m-1, whereas undoped NiO has 7.71 x 10-2 S.m-1.

Authors: Guerra Marco , Cesaroni Claudio , Ravanelli Michela , Spogli Luca
Published: May 2024

Due to advances in remote sensing of the Earth’s Ionosphere through Total Electron Content (TEC) estimates by Global Navigation Satellite System (GNSS) receivers, it is possible to detect and characterize Travelling Ionospheric Disturbances (TIDs) in both post-processing and, to some extent, in near real-time (NRT). A reliable and precise TEC filtering technique must be adopted to characterize waves accurately. Specifically, TEC detrending is widely adopted to extract the amplitude and period of the detected ionospheric waves from the background ionospheric conditions. Therefore, this study aims to understand and compare how different TEC detrending techniques and their settings impact the ability to extract such parameters. We highlight that the novel Fast Iterative Filtering (FIF) and the Savitzky-Golay filter (SGOLAY) techniques are the most reliable overall compared with moving average (MA), multi-order numerical difference (DD), polynomial detrending (POLY) and Finite Impulse response (FIR) band-pass filter (BUTF). Moreover, the impact of general algorithm settings on the exracted TID period is investigated, such as the Ionospheric Piercing Point (IPP) height and elevation cut-off angle, showing that such parameters drastically impact the retrieved period, especially for slower TIDs. Finally, due to the growing interest in real-time (RT) detection and classification of TIDs, the study proposes techniques for accurately estimating the TID amplitude in an NRT scenario. Such NRT techniques are then compared with the widely used post-processing products, such as the calibrated vertical TEC (vTEC), showing a difference that is mostly lower than the typical noise level of GNSS receivers (0.05 TECu).

Published: May 2024

Hintergrund Kolorektale Karzinome sind eine der häufigsten Krebserkrankungen in Europa. Moderne Therapieformen verbessern die Überlebenschancen; trotzdem sind die Erkrankung und ihre Behandlung mit einer hohen Morbidität verbunden. Körperliche Aktivität (KA) hat offensichtlich einen positiven Einfluss auf das Erkrankungsrisiko, die perioperative Komplikationsrate und die adjuvante Therapie.

Methode Grundlage für diese narrative Übersicht ist eine selektive Literatursuche in der Datenbank PubMed, ergänzt durch eine Suche in GoogleScholar bis 30.09.2022. Eingeschlossen wurden Originalarbeiten, Metaanalysen und systematische Reviews. Studien, die Bewegung und Ernährung analysierten, wurden ebenso berücksichtigt wie Leitlinien und Positionspapiere der deutschen, europäischen und amerikanischen Fachgesellschaften.

Ergebnisse Ein körperlich aktiver Lebensstil trägt über epigenetische Mechanismen zur Reduktion des Kolonkrebsrisikos bei. Je nach Studienprotokoll und Dosis der körperlichen Aktivität sind Risikoreduktionen zwischen 12 und 27 Prozent dokumentiert. Eine Prehabilitation aus Ernährung, Bewegung und psychologischer Unterstützung kann die peri- und postoperativen Ergebnisse beim kolorektalen Karzinom verbessern. Ausdauer- und Krafttraining können das rezidivfreie Überleben und die Tumorsterblichkeit verbessern. Keine Studie konnte eindeutige Verbesserungen bei Symptomabfragen (z.B. Fatigue) oder Biomarkern durch eine Ernährungsumstellung zeigen.

Schlussfolgerung Trotz einer Vielzahl an wissenschaftlichen Untersuchungen sind viele Fragen zum Einfluss von kA auf die verschiedenen Phasen einer Kolonkarzinomerkrankung nicht hinreichend geklärt. Empfehlungen zur Prehabilitation und zur Tertiärprophylaxe können aktuell nur auf Basis heterogener Studiendaten gegeben werden.

Objective The study's primary objective was to evaluate adverse outcomes among reproductive-age hospitalizations with diabetic ketoacidosis (DKA), comparing those that are pregnancy-related versus nonpregnancy-related and evaluating temporal trends.

Study Design We conducted a retrospective cross-sectional study using the National Inpatient Sample to identify hospitalizations with DKA among reproductive-age women (15–49 years) in the United States (2016–2020). DKA in pregnancy hospitalizations was compared with DKA in nonpregnant hospitalizations. Adverse outcomes evaluated included mechanical ventilation, coma, seizures, renal failure, prolonged hospital stay, and in-hospital death. Multivariable Poisson regression models with robust error variance were used to estimate adjusted relative risk (aRR) and 95% confidence interval (CI). Annual percent change (APC) was used to calculate the change in DKA rate over time.

Results Among 35,210,711 hospitalizations of reproductive-age women, 447,600 (1.2%) were hospitalized with DKA, and among them, 13,390 (3%) hospitalizations were pregnancy-related. The rate of nonpregnancy-related DKA hospitalizations increased over time (APC = 3.8%, 95% CI = 1.5–6.1). After multivariable adjustment, compared with pregnancy-related hospitalizations with DKA, the rates of mechanical ventilation (aRR = 1.56, 95% CI = 1.18–2.06), seizures (aRR = 2.26, 95% CI = 1.72–2.97), renal failure (aRR = 2.26, 95% CI = 2.05–2.50), coma (aRR = 2.53, 95% CI = 1.68–3.83), and in-hospital death (aRR = 2.38, 95% CI = 1.06–5.36) were higher among nonpregnancy-related hospitalizations with DKA.

Conclusion A nationally representative sample of hospitalizations indicates that over the 5-year period, the rate of nonpregnancy-related DKA hospitalizations increased among reproductive age women, and a higher risk of adverse outcomes was observed when compared with pregnancy-related DKA hospitalizations.

Background Lipedema is a chronic, incurable disorder characterized by painful fat accumulation in the extremities. While the application of liposuction in lipedema management has become increasingly popular, the safety and effectiveness of this approach remain contentious. Our systematic review and meta-analysis aimed to assess various liposuction modalities in lipedema management to verify their safety and efficacy.

Methods In-line with the Preferred Reporting Items for Systematic Reviews and Meta-analyses guidelines, we performed a comprehensive literature review from inception until March 2023 using the following electronic databases: CENTRAL, MEDLINE, Google Scholar, and EMBASE.

Results From the 562 initially identified articles, 20 met our inclusion/exclusion criteria for evaluation. Our review encompassed 14 prospective cohort studies, 3 retrospective studies, 2 case series, and 1 cross-sectional study. A meta-analysis of nine articles revealed a notable improvement in the quality of life, pain, pressure sensitivity, bruising, cosmetic impairment, heaviness, walking difficulty, and itching among lipedema patients who underwent liposuction. Although complications such as inflammation, thrombosis, seroma, hematoma, and lymphedema-related skin changes were reported, severe complications were rare. Crucially, no instances of shock, recurrence, or mortality were reported.

Conclusion Liposuction is a safe and beneficial therapeutic intervention for managing lipedema symptoms and enhancing quality of life. However, the impact of liposuction on secondary lymphedema remains unreported in the literature. Further high-quality, large-scale trials are necessary to assess the safety and effectiveness of different liposuction modalities. These studies will contribute valuable insights to optimize liposuction as a therapeutic option for individuals with lipedema.

Computational modeling of interval distributions in tonal space reveals paradigmatic stylistic changes in Western music history
Authors: Moss Fabian C. , Lieck Robert , Rohrmeier Martin
Published: May 2024

Diachronic stylistic changes in music are to a large extent affected by composers’ different choices, for example regarding the usage of tones, intervals, and harmonies. Analyzing the tonal content of pieces of music and observing them over time is thus informative about large-scale historical changes. In this study, we employ a computational model that formalizes music-theoretic conceptualizations of tonal space, and use it to infer the most likely interval distributions for pieces in a large corpus of music, represented as so-called ‘bags of tonal pitch classes’. Our results show that tonal interval relations become increasingly complex, that the interval of the perfect fifth dominates compositions for centuries, and that one can observe a stark increase in the usage of major and minor thirds during the 19th century, which coincides with the emergence of extended tonality. In complementing prior research on the historical evolution of tonality, our study thus demonstrates how example-based music theory can be informed by quantitative analyses of large corpora and computational models.

The thermophysical properties and elemental abundances of the noble gases in terrestrial materials can provide unique insights into the Earth’s evolution and mantle dynamics. Here, we perform extensive ab initio molecular dynamics simulations to determine the melting temperature and sound velocity of neon up to 370 GPa and 7500 K to constrain its physical state and storage capacity, together with to reveal its implications for the deep interior of the Earth. It is found that solid neon can exist stably under the lower mantle and inner core conditions, and the abnormal melting of neon is not observed under the entire temperature (T) and pressure (P) region inside the Earth owing to its peculiar electronic structure, which is substantially distinct from other heavier noble gases. An inspection of the reduction for sound velocity along the Earth’s geotherm evidences that neon can be used as a light element to account for the low-velocity anomaly and density deficit in the deep Earth. A comparison of the pair distribution functions and mean square displacements of MgSiO3–Ne and Fe–Ne alloys further reveals that MgSiO3 has a larger neon storage capacity than the liquid iron under the deep Earth condition, indicating that the lower mantle may be a natural deep noble gas storage reservoir. Our results provide valuable information for studying the fundamental behavior and phase transition of neon in a higher T–P regime, and further enhance our understanding for the interior structure and evolution processes inside the Earth.
