Massive black holes in nuclear star clusters
Authors: Hoyer N. , Arcodia R. , Bonoli S. , Merloni A. , Neumayer N. , Zhang Y. , Comparat J.
Published: January 2024

Context. Massive black holes (MBHs) are typically hosted in the centres of massive galaxies but they appear to become rarer in lower mass galaxies, where nuclear star clusters (NSCs) frequently appear instead. The transition region, where both an MBH and NSC can co-exist, has been poorly studied to date and only a few dozen galaxies are known to host them. One avenue for detecting new galaxies with both an MBH and NSC is to look for accretion signatures of MBHs.

Aims. Here, we use new SRG/eROSITA all-sky survey eRASS:4 data to search for X-ray signatures of accreting MBHs in NSCs, while also investigating their combined occupation fraction.

Methods. We collected more than 200 galaxies containing an NSC, spanning multiple orders in terms of galaxy stellar mass and morphological type, within the footprint of the German eROSITA Consortium survey. We determined the expected X-ray contamination from binary stellar systems using the galaxy stellar mass and star formation rate as estimated from far-ultraviolet and mid-infrared emission.

Results. We find significant detections for 18 galaxies (~8.3%), including one ultra-luminous X-ray source; however, only three galaxies (NGC 2903, 4212, and 4639) have X-ray luminosities that are higher than the expected value from X-ray binaries, indicative of the presence of an MBH. In addition, the X-ray luminosity of six galaxies (NGC 2903, 3384, 4321, 4365, 4639, and 4701) differs from previous studies and could indicate the presence of a variable active galactic nucleus. For NGC 4701 specifically, we find a variation of X-ray flux within the eRASS:4 data set. Stacking X-ray non-detected galaxies in the dwarf regimeM*gal≤ 109M⊙) results in luminosity upper limits of a few times 1038erg s−1. The combined occupation fraction of accreting MBHs and NSCs becomes non-zero for galaxy masses above ~ 107.5M⊙and this result is slightly elevated as compared to the literature data.

Conclusions. Our data extend, for the first time, towards the dwarf elliptical galaxy regime and identify promising MBH candidates for higher resolution follow-up observations. At most galaxy masses (and with the exception of three cases), the X-ray constraints are consistent with the expected emission from binary systems or an Eddington fraction of at most 0.01%, assuming a black holes mass of 106.5M⊙. This work confirms the known complexities in similar-type of studies, while providing the appealing alternative of using X-ray survey data of in-depth observations of individual targets with higher resolution instruments.
Mapping thermal emission in the synchrotron-dominated supernova remnants G330.2+1.0, 3C58, and RX J1713.7-3946
Authors: Picquenot A. , Williams B. J. , Acero F. , Mori K.
Published: January 2024

Aims. Since the discovery of synchrotron X-ray emission from the shell of the supernova remnant (SNR) SN 1006, multiple observations from Chandra and XMM-Newton have shown that many young SNRs produce synchrotron emission in X-rays. Among those, a few peculiar SNRs have their X-ray emission largely dominated by synchrotron radiation, showing no or only faint traces of thermal emission. In this paper, we report our mapping of the thermal emission in three emblematic synchrotron-dominated SNRs: G330.2+1.0, 3C58, and RX J1713.7-3946.

Methods. We used a blind source separation method able to retrieve faint components from X-ray data in the form of Chandra and XMM-Newton observations. The thermal candidates disentangled by the algorithm were then used to select regions of extraction. We then analyzed the extracted spectra to assess their physical nature.

Results. We conclude that the components retrieved by the algorithm indeed represent the spatial distribution of the thermal emission in G330.2+1.0 and 3C58, and a likely thermal candidate in RX J1713.7-3946. Our findings confirm and expand on past studies.
The SRG/eROSITA all-sky survey

Published: January 2024

Context. The first eROSITA all-sky survey (eRASS1) performed on board the Spectrum-Roentgen-Gamma mission (SRG) provides more than 900 000 X-ray sources in the 0.2–2.3 keV band located in the western hemisphere.

Aims. We present identifications of the eRASS1 sources obtained using our HamStar method, which was designed for the identification of coronal X-ray sources.

Methods. HamStar is a Bayesian framework that estimates coronal probabilities for each eRASS1 source based on a cross-match with optical counterparts from Gaia DR3. It considers geometric properties, such as angular separation and positional uncertainty, as well the additional properties of fractional X-ray flux, color, and distance.

Results. We identify 138 800 coronal eRASS1 sources and estimate a completeness and reliability of about 91.5% for this sample, which we confirmed with Chandra detections. This is the largest available sample of coronal X-ray emitters and we find nearly five times as many coronal sources as in the ROSAT all-sky survey. The coronal eRASS1 sources are made up of all spectral types and the onset of convection and the saturation limit are clearly visible. As opposed to previous samples, rare source types are also well populated. About 10% of the coronal eRASS1 sources have a correlated secondary counterpart, which is a wide binary companion or belongs to the same stellar cluster. We also identify 6700 known unresolved binaries, and an excess of fast binary periods below 10 d. Furthermore, the binary sequence is clearly visible in a color–magnitude diagram. When combining the coronal eRASS1 sources with rotation modulations from Gaia DR3, we find 3700 X-ray sources with known rotation periods, which is the largest sample of this kind. We fitted the rotation–activity relation and convection turnover times for our flux-limited sample. We do not detect the low-amplitude fast rotators discovered in the Gaia DR3 sample in X-rays.

Published: January 2024

Natural food preservative as marinade solution is the safest alternative to improve fish meat edible quality. Daily spices such as garlic, chili paste, pepper and asam sunti (a fermented fruit of Averrhoa bilimbi L.) are used as marination ingredients. Marination treatment is carried out for several period of storage which are 24 hours, 48 hours and 72 hours at (0 h 1)°C for each spice and for the mixture spices. The hedonic tests used include appearance, aroma, colour, taste, and texture of fish flesh. Compared to the control one, marination on tuna fish flesh can increase hedonic value of fish and showed that the spices have potential to improve edible quality of fish by increasing appearance, tenderness, and enriching the flavour of fish. Garlic marination on tuna fish flesh give a good result in preserving and in increasing consumer preference in grilled aroma, garlic aroma, savoury taste, and tenderness of fish flesh. Meanwhile the mixture spices marination on fish flesh has a moderate consumer preference on cooked fish.
Stability Analysis of Prey-Predator Model Migration with Holling Type-III Response Function in The Presence of Competition and Toxicity
Authors: Agus Syamsul , Toaha Syamsuddin , Kasbawati  , Khaeruddin
Published: January 2024

In this paper, we propose and investigate a prey-predator model with two zones contaminated with heavy metal toxicity, especially copper (Cu), which enter the reservation zone and the unreserved zone in the aquatic environment. The dynamics of the prey population in the ecosystem can migrate from the reservation zone to the unreserved zone or vice versa, while predators are assumed to look for prey in the unreserved zone. The dynamic behavior of the population is expressed as a system of differential equations based on food intake capacity and other factors. We introduce a predator population with a Holling type III predation response function, coupled with inter-specific competition among prey due to overlapping diets and assuming the prey is contaminated with copper metal toxicity. The presence of a positive equilibrium point, namely the interior equilibrium point, is analyzed and investigated for its stability using the Routh-Hurwitz stability test. Numerical simulations are carried out to verify the results of the analysis and dynamics of the system solution. The results of the analysis of the interior equilibrium point T3 in each case is a stable point. This indicates a change in the balance of prey populations and predator populations.

Authors: Widyaningrum Retno , Herdiyawati Lilik
Published: January 2024

Teman Bus was established by the Ministry of Transportation to improve the safety, security, and convenience of mobilization. Teman Bus services can be accessed through the Teman Bus application (Teman Bus Apps), which makes it easier for consumers to search for bus information. However, the design of the application is not good, this can impact on reducing consumer interest in continuing to use the application. The concept of emotional design and human performance has a significant relationship with consumer intention to use technology. The research purposes are to determine the effect of emotional design on consumer intention to use the Teman Bus Apps and the effect of human performance on consumer trust in using the Teman Bus Apps. The study method was based on an online survey questionnaire and completing tasks for students in Surabaya who have used the Teman Bus Apps. The present research results reveal that usability and information quality variables as a representation of the emotional design aspect had a significant effect on students’ intention to use the Teman Bus Apps, while the human performance aspect did not have a significant effect.
Mid-gastric peroral endoscopic myotomy in the treatment of post-sleeve gastrectomy gastric tube twist: Four cases
Authors: Mugnier Angelique , Vitton Veronique , Barthet Marc , Gonzalez Jean-Michel
Published: January 2024

Background and study aims Laparoscopic sleeve gastrectomy (LSG) may lead to symptomatic mid-gastric twist in 0.1% to 4% of cases. Endoscopic balloon dilatation often fails, requiring a switch to Roux-en-Y bypass. Submucosal endoscopic treatment is expanding, so we propose a new technique of fibrosis incision after tunnelization, called medio-gastric peroral endoscopic myotomy (MG-POEM).

Patients and methods Four patients aged 41 to 70 years underwent MG-POEM in 2020 for symptomatic post-LSG medio-gastric twist. The aim was to describe the technique, and document the efficacy, using the Gastric Outlet Obstruction Scoring System (GOOSS) score and a quality-of-life scale (QOLS). The procedures consisted of a POEM with myotomy and fibrosis incision.

Results Median preoperative GOOSS and QOLS were 1/3 ([0–3] and 1.75/10 [0–10], respectively. All procedures were technically successful. One patient had immediate postoperative complications, which were treated conservatively. The median follow-up was 18 months. All patients had improved quality of life and food intake, with median postoperative GOOSS and QOLS of 3/3 and 6,5/10 [6–8], respectively. Two patients required additional pneumatic dilatation for scarring strictures. Follow-up endoscopies and esophagograms showed that the twist had disappeared.

Conclusions MG-POEM shows promise for safe and effective management of post-LSG mid-gastric twist, despite requiring a high level of endoscopic skill to perform submucosal tunneling.
Single Incision Dual Cover with Temporoparietal Fascial Flap for Exposed Cochlear Implant: A Novel Take on a Workhorse Flap
Authors: Begum U. Rasheedha , Kandasamy Mahadevan , Christabel Prethee Martina
Published: January 2024

Cochlear implant surgeries have become increasingly common in India, leading to a rise in complications such as cochlear implant exposure. To address this issue, we present a novel technique involving a single incision dual cover using the temporoparietal fascial flap (TPFF) and skin flap to give durable cover for exposed cochlear implants.

Materials and Methods A retrospective study was conducted between December 2019 and December 2022 on patients who underwent the dual flap procedure for exposed cochlear implants.

Results The average defect size was 2 × 2 cm, and the average length of hospital stay was 10 days. Fourteen skin flaps were closed primarily, while two required skin grafting for donor site closure. At the time of discharge, all wounds showed successful healing with intact skin coverage over the cochlear implant device site. The average follow-up period was 12 months, during which two patients had donor site scar alopecia, while others had adequate hair growth masking the scar. All patients consistently used their cochlear implants.

Conclusion Our single-incision, dual cover TPFF + skin flap technique offers a reliable and innovative solution for managing exposed cochlear implants. With successful implant salvage and favorable postoperative outcomes, this approach demonstrates the versatility and reliability of the TPFF as an excellent option for reconstructive surgeons dealing with cochlear implant complications.
Liberal and illiberal industrial policy in the EU: the political economy of building the EV battery value chain in Sweden and Hungary
Authors: Győrffy Dóra
Published: January 2024

In the context of an increasingly ambitious European Union (EU) industrial policy and the transition to electromobility, the main objective of the article is to uncover the interaction between the supranational level and domestic policies through examining the buildup of the electric vehicle (EV) battery value chain in illiberal Hungary and liberal Sweden. The study analyses these diverse cases through the lenses of comparative political economy. How do European industrial policy objectives translate into national policies under widely different political conditions? How do the different translations impact on the original objectives of EU policy? Through using a structured-focused comparison, the paper argues that the building of the EV battery industry implies the entrenchment of existing models of capitalism in both cases. Liberal democracy is only compatible with the coordinated market economy model of Sweden, while in Hungary the illiberal regime and the dependent market economy model reinforce one another in face of growing public recognition of the disadvantages of dependency—misallocation of resources, environmental damage, and limits to upgrading. EU strategic objectives are served only by the Swedish model, while the Hungarian model leads to deepening institutional cleavages within the EU and implies growing dependence on Russia and China.

It employs the Elaboration Likelihood Model (ELM) and text data mining to examine how information strategies from government, businesses, and media influence consumer attitudes toward green consumption. The findings reveal that women and individuals in economically developed regions show more concerns for green consumption. The public responds positively to government policies and corporate actions but negatively to media campaigns. Engagement with information and emotional responses influence attitudes toward green consumption. Subsequently, this study offers strategies for policymakers and businesses to enhance consumer attitudes and behaviors toward green consumption, promoting its development. Moreover, the innovative aspect of this study is the combination of ELM theory and text data mining techniques to monitor public attitude change, applicable not only to green consumption but also to other fields.

Regulating inbound foreign direct investment in a world of hegemonic rivalry: the evolution and diffusion of US policy
Authors: Li Jing , Shapiro Daniel , Ufimtseva Anastasia
Published: January 2024

We employ insights from the international relations literature to offer a novel perspective on the regulation of inbound foreign direct investment (FDI). We argue that in a world of hegemonic rivalry, the incumbent, when it perceives a threat, tends to employ both internal and external policy mechanisms to maintain the balance of power. Specifically, in response to China’s rise, the US expanded its internal national security review regulations, moving from a primary focus on FDI by state-owned enterprises (SOEs) to including Chinese investments in a broad set of strategic industries, regardless of ownership. External mechanisms include the diffusion of those internal regulations to allied countries, and we focus on a specific Alliance, the Five Eye (FVEY) intelligence alliance. Empirically, we combine natural language processing of keywords with close reading of selected documents to analyze FDI regulations in the US and FVEY allies. The results suggest that the US is an early adopter of both SOE and broader FDI regulations targeting strategic sectors for national security considerations. While SOE regulations exhibit relatively limited evidence of convergence, we find a more significant and recent convergence between the US and its alliance partners on the national security reviews of FDI in strategic sectors.
Enhancing short-term wind power forecasting accuracy for reliable and safe integration into power systems: A gray relational analysis and optimized support vector regression machine approach
Authors: Liu Yuwei , Li Lingling , Liu Jiaqi
Published: January 2024

The reliability and safety of power systems heavily depend on accurate forecasting of new energy generation. However, the non-stationarity and randomness of new energy generation power increase forecasting difficulty. This paper aims to propose a short-term wind power forecasting method with strong characterization ability to accurately understand future new energy generation conditions so as to ensure power systems' reliability and safety. The required input variables for wind power forecasting are determined by the gray relational analysis method. An advanced marine predators algorithm is proposed by improving the marine predators algorithm to enhance convergence ability and probability of escaping local optimal solutions. The advanced marine predators algorithm optimizes support vector regression machine to address the issue of insufficient utilization of its forecasting performance due to the selection of parameter values based on personal experience in traditional methods. Finally, different wind power generation scenarios verify its effectiveness and universality. This study promotes the application of artificial intelligence technology for improving short-term wind power forecasting accuracy, thereby enhancing the reliability and safety level of power systems.
Expected Bayesian estimation based on generalized progressive hybrid censored data for Burr-XII distribution with applications
Authors: Nagy M.
Published: January 2024

In the Bayesian estimation method for the parameters of random distributions, the process of selecting hyperparameters for the prior distributions is one of the important and complex matters that determine the efficiency of the estimation. Therefore, researchers have recently been interested in the expected Bayesian (E-Bayes) estimation as a solution to hyperparameter problems. In this paper, we discuss the Bayes and E-Bayes estimation process based on generalized type-I hybrid censored data from Burr-XII distribution. We used symmetric and asymmetric loss functions, such as squared error, Degroot, quadratic, and linear exponential loss functions. All of these methods were compared using Monte Carlo simulations, using which mean square errors and average of estimators were calculated. Moreover, real data were used as an applied and illustrative example. Finally, some conclusions were drawn in the concluding comments of this paper.

Published: January 2024

Mixed flow pump has received widespread applications in various perspectives, therefore, enhancing the operational stability is crucial to pump design and applications. To address this phenomenon, the present work explores the efficacy of fluid–structure coupling approach to analyze the vibration characteristics and fluid-excited dynamic properties of mixed flow pump. In this study, ANSYS Workbench is employed for static and modal analysis of the pump, while dynamic analysis is performed based on the outcomes of unsteady fluid analysis. The findings, however, revealed that the guide vane region registered the largest stress and most violent deformation in the entire pump. Compared with other parts of the pump body, the thickness of the guide vane is relatively small, and at the same time, considering the influence of periodic changes in the pressure in the flow channel, its strength should be considered in the design while preventing fatigue damage, and the material and processing method should be selected to meet the requirements. Meanwhile, at the entrance of the guide vane, the impeller rotation attained supremacy in the fluid pressure pulsation, and at the same time, a low-frequency pulsation caused by the vortex structure in the guide vane emanate in the channel. It is worth noticing that both blade deformation and equivalent stress depicted periodic variations. Interestingly, the blades recorded the modest values for both maximum average equivalent stress and maximum average total deformation at the design operating points. However, at over-load operating points, the blades registered their maximum values. The conclusions of this study could lay a foundation for conducting stability analysis on mixed-flow pumps and optimizing the design of the guide vane.

Published: January 2024

We perform a comparative study of the phase noise induced in the lasers used for Bragg diffraction in a Bose–Einstein condensate-based quantum gravimeter where the Bragg beams are generated using two different configurations. In one of the configurations, the Bragg beams that form the moving optical lattice are generated using two different acousto-optic modulators. In the second configuration, the Bragg beams are generated using a single acousto-optic modulator carrying two phase-locked frequencies. The second configuration shows a suppression of the phase noise by a factor of 4.7 times in the frequency band up to 10 kHz, the primary source of noise, which is the background acoustic noise picked up by optical components and the optical table. We report a short-term sensitivity of 1360μGal/Hz and upon integration over 200 s, achieve a resolution of 99.7 μGal for an interferometric duration of 10 ms.

Published: January 2024

Oxygen evolution reaction (OER) is the pivotal obstacle of water splitting for hydrogen production. Dual-sites catalysts (DSCs) are considered exceeding single-site catalysts due to the preternatural synergetic effects of two metals in OER. However, appointing the specific spatial configuration of dual-sites toward more efficient catalysis still remains a challenge. Herein, we constructed two configurations of Fe–Co dual-sites: stereo Fe–Co sites (stereo-Fe-Co DSC) and planar Fe–Co sites (planar-Fe-Co DSC). Remarkably, the planar-Fe-Co DSC has excellent OER performance superior to stereo-Fe-Co DSC. DFT calculations and experiments including isotope differential electrochemical mass spectrometry, in situ infrared spectroscopy, and in situ Raman reveal the *O intermediates can be directly coupled to form *O–O* rather than *OOH by both the DSCs, which could overcome the limitation of four electron transfer steps in OER. Especially, the proper Fe–Co distance and steric direction of the planar-Fe-Co benefit the cooperation of dual sites to dehydrogenate intermediates into *O–O* than stereo-Fe-Co in the rate-determining step. This work provides valuable insights and support for further research and development of OER dual-site catalysts.

An enhanced sparse autoencoder for machinery interpretable fault diagnosis
Authors: Niu Maogui , Jiang Hongkai , Wu Zhenghong , Shao Haidong
Published: January 2024

The interpretability of individual components within existing autoencoders remains insufficiently explored. This paper aims to address this gap by delving into the interpretability of the encoding and decoding structures and their correlation with the physical significance of vibrational signals. To achieve this, the Sparse Coding with Multi-layer Decoders (SC-MD) model is proposed, which facilitates fault diagnosis from two perspectives: the working principles of the model itself and the evolving trends of fault features. Specifically, a sparse coding protocol to prevent L1-norm collapse is proposed in the encoding process, regularizing the encoding to ensure that each latent code component possesses variance greater than a fixed threshold on a set of sparse representations given the input data. Subsequently, a multi-layer decoder structure is designed to capture the intricate mapping relationship between features and fault patterns. Finally, the Fast Iterative Shrinkage-Thresholding Algorithm (FISTA) is employed as the solver for the SC-MD model, enabling end-to-end updates of all parameters by unfolding FISTA. The coherent theoretical framework ensures the interpretability of SC-MD. Utilizing aeroengine bearing data, we demonstrate the exceptional performance of our proposed approach under both normal conditions and intense noise, as compared to state-of-the-art deep learning methods.

Authors: Gousiya Bhanu Ganganapalli , Manmadha Rao B
Published: January 2024

In recent years, anodic TiO2 nanotubes (TNTs) have been considered as one of the most promising material in the field of photoelectrochemical water splitting, hydrophobic coatings, solar cells etc owing to their outstanding properties such as unidirectional charge transfer, high surface to volume ratio along with the non-toxicity, corrosion resistance, high thermal and chemical stabilities. In the present study, TNTs were successfully fabricated using a simple and low cost electrochemical anodization technique at 30 V and 60 V. The morphological and structural information of the TiO2 nanotube arrays were investigated through SEM and XRD analysis. This analysis revealed that fabricated nanotubes were having a set of length and pores diameters (2.5 μm, 70 nm), (17 μm, 120 nm) respectively for 30 V TNTs and 60 V TNTs samples. Electronic band gap and surface functional groups of TNTs were examined by diffuse reflectance and attenuation total reflection spectroscopy studies. This analysis divulged that fabricated sample surface was free from chemicals and energy band gap found to be around 3.2 eV. The contact angle measurement revealed that as-fabricated 30 V TNTs sample has shown an enhanced hydrophobic nature (135.9°) and whereas annealed 60 V TNTs sample has shown an enhancement in the photocurrentdesnity (70.7 μA.cm−2). These findings show that fabricated TNTs can be used in hydrophobic coatings along with photocatalytic applications.
