Published: January 2025

Context. Open star clusters are dynamic systems whose evolution is critically influenced by initial conditions such as star formation efficiency and orbital parameters. Understanding their dissolution mechanisms provides insight into stellar population dynamical mixing in the Milky Way.
Aims. We aim to investigate the dynamical evolution and dissolution of initially non-virialised open clusters by examining how different global star formation efficiencies and orbital characteristics impact the cluster longevity and structural changes. We followed the evolution of the clusters up to their dissolution time on the basis of our calculations. Finally, we also compare our open cluster dynamical evolutionary models with the observed open clusters in our Galaxy’s solar vicinity.
Methods. Using high-order direct N -body simulations, we modelled cluster evolution across different Galactic orbits, systematically varying initial star formation efficiencies to comprehensively explore dissolution mechanisms.
Results. Our simulations reveal that open clusters typically survive approximately ten orbital periods, with cluster lifetime being strongly dependent on global star formation efficiency and only marginally influenced by orbital eccentricity. We estimate gas expulsion timescales of ∼0.9 Myr, with initial supernova explosions efficiently removing gaseous components from the cluster. The expected lifetime of the cluster (in units of orbital periods) strongly depends on the cluster global star-formation efficiency and only slightly on the orbital eccentricities of the cluster.
Conclusions. The theoretical models demonstrate a remarkable agreement of the Roche-lobe filling parameter with the recent observed Gaia DR3 cluster catalogues in the solar vicinity. By incorporating a mixed sample of clusters with varying star formation efficiencies, we provide a more nuanced understanding of open cluster evolution in the Galactic disc.

Authors: Karampinis Ioannis , Galata Christian , Rößner Eric Dominic , Stamenovic Davor 
Published: January 2025

ZusammenfassungEine 60-jährige Patientin wurde zur weiteren Diagnostik einer Raumforderung des
hinteren Mediastinums vorgestellt. Die Raumforderung wurde als Zufallsbefund im Rahmen
einer CT-Thorax-Untersuchung diagnostiziert. Grund für die extern durchgeführte
Schnittbildgebung war ein erhöhter CA-19–9-Wert in einer Routine-Blutentnahme gewesen.
Zum Zeitpunkt der Erstvorstellung in unserer Klinik war die Raumforderung bereits 2-mal
biopsiert worden (einmal CT-gesteuert und einmal endosonografisch), aber die
Histopathologie war in beiden Fällen nicht zielführend. Mit der Patientin wurde die
Wiederholung der CT-gesteuerten Punktion und des transösophagealen Ultraschalls
besprochen. Auch in unserer Klinik haben die Biopsien keinen weiterführenden Befund
ergeben. Die Endosonografie hatte keine Infiltration des Ösophagus gezeigt. Mit der
Patientin wurde eine thorakoskopische Exploration besprochen. Der Eingriff wurde über
einen rechtsseitigen uniportal-thorakoskopischen Zugang begonnen. Nach Mobilisation der
Läsion vom rechten Unterlappen durch eine atypische Resektion wurde die Raumforderung
vom Zwerchfell und den mediastinalen Verwachsungen mobilisiert. Ein zuführendes Gefäß
von der Aorta descendens wurde ligiert, und die Patientin wurde umgelagert, um den
Eingriff von der linken Seite fortzuführen. Über einen linksseitigen
uniportal-thorakoskopischen Zugang wurde die Raumforderung vom Zwerchfell und der Aorta
descendens mobilisiert. Eine Invasion der linken Lunge konnte nicht nachgewiesen werden.
Nach Komplettierung der Mobilisation konnte die Raumforderung vollständig über den
linksseitigen Zugang geborgen werden. Die histopathologische Aufarbeitung des Präparates
bestätigte einen extralobären pulmonalen Sequester.

Authors: Singh Amandeep , Arora Manik , Awal Guneet , Sood Mehar Kaur 
Published: January 2025

Abstract
Background Diabetes mellitus (DM) leads to diabetic peripheral neuropathy (DPN), a significant complication affecting a large percentage of diabetic patients. Traditional methods like nerve conduction studies have limitations in diagnosing DPN, especially in advanced cases. High-resolution ultrasound has emerged as a valuable tool in enhancing diagnostic accuracy.
Objective The aim of the study is to evaluate the efficacy of shear wave elastography (SWE) in assessing DPN, focusing on the tibial and median nerves.
Materials and Methods The study involved 100 participants categorized into groups with DPN, DM without DPN, and healthy controls. SWE was performed on the tibial and median nerves, and statistical analysis was conducted to compare the findings among the groups.
Results The study found significant increases in SWE values from the normal group to the DM group, and further increases in the DPN group for both tibial and median nerves. Receiver operating characteristic analysis indicated high diagnostic accuracy of SWE in distinguishing DPN from non-DPN cases. Overall, the study suggests that SWE could be a valuable adjunctive imaging tool in diagnosing DPN, offering advantages in terms of sensitivity, specificity, and noninvasiveness.
Conclusion The study concludes that SWE of the tibial and median nerves is a noninvasive, sensitive, and specific method for detecting DPN. Combining high-resolution ultrasound with SWE enhances the diagnostic accuracy of DPN.

ResumoO objetivo dos autores é apresentar uma nova técnica de coxoplastia que resolva o desconforto e estigma associados a cicatrizes na virilha ou outras regiões anteriores do corpo após coxoplastias convencionais.O estudo apresenta um relato de caso de uma técnica de coxoplastia realizada em pacientes pós-bariátricas submetidas a intenso emagrecimento, por meio de ressecção de pele em S realizada na região póstero-medial da coxa, sem cicatriz na parte anterior do corpo. As pacientes não apresentaram complicações pós-operatórias e apresentaram cicatrizes discretas. Além disso, a técnica consegue uma grande redução do excesso de pele, em múltiplos vetores, melhorando o contorno corporal.A técnica envolve o posicionamento inédito da cicatriz em forma de S nos sulcos sub-glúteos e posteromediais das coxas, sem cicatriz anterior na virilha, melhorando significativamente o ocultamento da cicatriz. Permite também não ter angulações na linha de sutura, melhor distribuição das trações cutâneas, menor chance de deiscência da ferida, ao mesmo tempo em que permite a ressecção de grandes quantidades de excesso de pele nas direções longitudinal e transversal, com tração em múltiplos vetores.A técnica de coxoplastia apresentada é um procedimento inovador, inédito, que permite um melhor ocultamento da cicatriz e provável menor incidência de complicações devido à melhor distribuição da tensão cicatricial.

Consonant stability in Portuguese-based creoles
Authors: Silva Carlos , Moran Steven 
Published: January 2025

Abstract
Research on language stability typically departs from a sample
of mother-daughter languages (e.g., Greenhill et al. 2017, Honeybone
2019, Moran et al. 2021).
Instead, this study aims at measuring consonant stability (presence or absence
of change) in Portuguese-based creoles. Our approach enables us to: (i) build a
stability scale of the adaptation of shifted phonological systems, and (ii)
measure distances between creoles with regard to their lexifier. Our hypothesis
is that less stable segments are typologically rare and that they were unstable
in Portuguese from the 16th century until today. Our main findings are: (i)
consonant stability is strongly correlated to typological frequency, (ii) the
similarity between the consonant systems of the substrates and the lexifier does
not affect the stability scores, and (iii) the sociohistorical characteristics
of each settlement, namely the duration and the conditions of contact, play a
role on phonological stability in the creoles under observation.

Main text
Inherited metabolic disorders affect approximately 1 in 1000 babies; amino acid disorders are less frequent, at approximately 1 in 6000. Babies diagnosed with amino acid disorders require constant monitoring of amino acid blood concentration, especially for disease states such as phenylketonuria. In addition, amino acid measurement may aid in the evaluation of several other disorders such as neurological and nutritional disorders. Free amino acids in healthy patients are typically in the low mg/kg range but, for example, elevated phenylalanine indicates phenylketonuria disease state. Evidence of successful participation in formal, relevant international comparisons is needed to document calibration and measurement capability claims (CMCs) made by national metrology institutes (NMIs) and designated institutes (DIs).
This Track A study is being used to assess the core competencies of the National Metrology Institutes/Designated Institutes (NMIs/DIs) for provision of measurement services. The aim of this study is to assess the performance of the NMIs/DIs for a matrix material for clinical analytes. This follows and builds on the successful CCQM-K109 study on urea and uric acid in human serum.
Eleven NMIs participated in the Track A Key Comparison CCQM-K159 Free amino acids in plasma. NMIs/DIs were given the option of taking part in a parallel pilot study CCQM-P202, however all participants opted for the Track A key comparison and there were no participants for CCQM-P202. Participants were requested to evaluate the mass fractions, expressed in mg/kg, of DL-phenylalanine and DL-leucine in pooled frozen human plasma with lithium heparin added as an anticoagulant.
Successful participation in CCQM-K159 demonstrates the following measurement capabilities in determining mass fraction of organic compounds, with molecular mass of 50 g/mol to 500 g/mol, having high to mid polarity pKow > -4, in mass fraction range from 1 mg/kg to 1000 mg/kg in a biological matrix such as human plasma, serum and urine.

Published: January 2025

Abstract
Condition recognition in coal flotation is a critical component in achieving flotation process control and optimization. To develop reliable models for condition recognition, two key challenges must be addressed: first, the effective extraction and integration of froth visual feature information from multiple flotation cells; and second, the fusion of froth visual features with process parameters to create a comprehensive representation of flotation conditions. To tackle these challenges, a time series classification model based on multi-source heterogeneous data was proposed for coal flotation condition recognition. First, a bubble size feature representation method combining the tsfresh and maximum relevance minimum redundancy algorithms was proposed. This method accurately describes bubble size distribution features through multi-scale feature extraction and mutual information-based feature selection. Next, a neural network feature evaluation model based on L1 regularization was presented, which quantifies the importance of visual features through the sparse expression of network weights, facilitates feature selection, and applies the resulting feature weights to the subsequent weighting process in classification models. Finally, a residual temporal network that integrates residual feature extraction and temporal modeling was proposed. This model employs one-dimensional convolution and cascaded residual structures for deep feature extraction, while temporal dependencies of condition changes are captured by combining long short-term memory and attention mechanisms. Validation on a flotation froth dataset collected from field sites in Anhui demonstrates that the proposed model achieves a condition classification accuracy of 85.08%, significantly improving the performance of flotation condition recognition compared to existing models.
Fourier transform digital moiré interferometry

Published: January 2025

Abstract
Processing interferometric images is a key task in optical interferometry for measurement purposes. It is well known that there are two main kinds of interferograms: those with open fringes and those with closed fringes. Often, processing a single interferogram with closed fringes can be challenging; therefore, applying phase-shifting is almost obligatory. However, it requires several images and a high precision mechanical device to achieve accurate results. On the other hand, interferograms with open fringes are more straightforward to process. However, precise knowledge of the carrier frequency of the fringes is essential for accurate processing. An alternative solution to the challenges posed above is the use of digital moiré interferometry, which consists of superimposing a reference interferogram and another obtained with the object to be measured. In this work we propose a digital moiré interferometry method that uses the Fourier transform and Butterworth-type filters. The feasibility and versatility of the proposed method is experimentally demonstrated using a Mach–Zehnder-type interferometer to analyze gas flow in a flame.
Algebraic identifiability of partial differential equation models

Published: January 2025

Abstract
Differential equation models are crucial to scientific processes across many disciplines, and the values of model parameters are important for analyzing the behaviour of solutions. Identifying these values is known as a parameter estimation, a type of inverse problem, which has applications in areas that include industry, finance and biomedicine. A parameter is called globally identifiable if its value can be uniquely determined from the input and output functions. Checking the global identifiability of model parameters is a useful tool when exploring the well-posedness of a given model. This problem has been intensively studied for ordinary differential equation models, where theory, several efficient algorithms and software packages have been developed. A comprehensive theory for PDEs has hitherto not been developed due to the complexity of initial and boundary conditions. Here, we provide theory and algorithms, based on differential algebra, for testing identifiability of polynomial PDE models. We showcase this approach on PDE models arising in the sciences.

Abstract
The Dark Energy Spectroscopic Instrument (DESI) will provide unprecedented information
about the large-scale structure of our Universe. In this work, we study the robustness of the
theoretical modelling of the power spectrum of Folps, a novel effective field theory-based
package for evaluating the redshift space power spectrum in the presence of massive neutrinos. We
perform this validation by fitting the AbacusSummit high-accuracy N-body simulations
for Luminous Red Galaxies, Emission Line Galaxies and Quasar tracers, calibrated to describe DESI
observations. We quantify the potential systematic error budget of Folps finding that the
modelling errors are fully sub-dominant for the DESI statistical precision within the studied
range of scales. Additionally, we study two complementary approaches to fit and analyse the power
spectrum data, one based on direct Full-Modelling fits and the other on the ShapeFit compression
variables, both resulting in very good agreement in precision and accuracy. In each of these
approaches, we study a set of potential systematic errors induced by several assumptions, such as
the choice of template cosmology, the effect of prior choice in the nuisance parameters of the
model, or the range of scales used in the analysis. Furthermore, we show how opening up the
parameter space beyond the vanilla ΛCDM model affects the DESI observables. These studies
include the addition of massive neutrinos, spatial curvature, and dark energy equation of
state. We also examine how relaxing the usual Cosmic Microwave Background and Big Bang
Nucleosynthesis priors on the primordial spectral index and the baryonic matter abundance,
respectively, impacts the inference on the rest of the parameters of interest. This paper
pathways towards performing a robust and reliable analysis of the shape of the power spectrum of
DESI galaxy and quasar clustering using Folps.

Abstract
T2K is a long baseline neutrino experiment, entering Phase II with a Near Detector upgrade. The T2K near detector (ND280) upgrade consists of the installation of three new detector systems: a plastic scintillator neutrino active target (Super-FGD), two time projection chambers (HA-TPC) and a time of flight detector (TOF). The Super-FGD is composed of 2-million 1 cm3 scintillating cubes read by almost 60 thousand wavelength-shifting (WLS) fibers coupled to an MPPC on one end. Given the large number of channels, the limited space inside magnetic environment, and the limited time from production to installation, the development and testing of the Front-end electronics boards (FEB) for the read-out of the Super-FGD channels represented a challenging task for the success of the upgrade.

This work presents the performance tests confirming that the FEB aligns with detector requirements, and the hardware qualification of 240 FEBs through a custom QC test bench designed to detect and locate hardware failures to speed up the repairing process. Installation of the electronics in the detector took place in March 2024, one year after the beginning of the FEB mass production, and the first successful neutrino beam run took place in June of the same year.
Study on joint de-noising method of ECG signals with improved CEEMDAN-wavelet thresholding and singular spectrum analysis

Published: January 2025

Abstract
The electrocardiogram (ECG) signal is often contaminated by various noises during acquisition and transmission, and the denoising effect directly affects the diagnosis of heart diseases. To improve the denoising effect, this paper proposes an improved Complete Ensemble Empirical Mode Decomposition (CEEMDAN)-wavelet thresholding and singular spectrum analysis (SSA) joint denoising method. First, the noise-dominated high-frequency intrinsic mode function (IMF) is identified using CEEMDAN; second, it is denoised to reduce high-frequency noise by the improved wavelet thresholding technique; and then, SSA is used to remove baseline wander (BW); finally, to verify the effectiveness of this denoising method, the root mean square error (RMSE) and signal-to-noise ratio (SNR) are used as the evaluation criteria for the denoising effect and the standard MIT-BIH ECG noise database signals are used for verification. The validation results show that compared with the existing ECG denoising methods, the denoising method improves the SNR by 39%∼ 55% and reduces the RMSE by 18%∼ 42%. The method can be used as an effective tool for ECG signal denoising and provide a better basis for diagnosis in computerized automated medical systems.
