Combining parametric discreteness and continuity for analyzing dynamic models of structures
Authors: Sobolev V. I. , Karmazinov D. A. , Chernigovskaya T. N. 
Published: January 2025

This paper describes a method for building dynamic models that contain rod bending elements with distributed and concentrated inertial and stiffness parameters, and their analysis based on the harmonic element method. As a rule, the vibration effects of structures are calculated on the basis of mass discretization, although the application of such methods entails certain difficulties.Discrete models are considered to be a priori approximations with limited possibilities of error estimation. The dynamic parameters of the model vary depending on its dimensionality as well as on the transformation methods. Numerical results with arrays and matrices of high dimensionality make it difficult to analyze and evaluate the calculation results. Therefore, structural calculations for stationary dynamic effects based on the use of elements with distributed and concentrated masses prevent the above-mentioned consequences of full discretization. However, such discrete-continuum (hybrid) dynamic models require the sewing of heterogeneous elements at the formation stage. In addition, some complications occur when solving these combined systems containing ordinary differential equations and partial differential equations. These issues can be solved by using the author's harmonic element method, implementing the nodal sewing of heterogeneous elements, as well as providing solutions as amplitudes of oscillations of the combined model nodes along certain necessary directions. The specified features of the proposed method allow us to identify it as a separate class with the name of the harmonic element method.

The present study is aimed at the directed synthesis of a new ternary molybdate K5Pb0.5Zr1.5(MoO4)6 isostructural to K5Pb0.5Hf1.5(MoO4)6 by solid-phase reaction within the temperature range of 350–550 °С (for 100 h). The compound crystallizes in the rhombohedral system with the space group R3̅ and unit cell parameters of a = 10.6604(2) Å, c = 37.9769(9) Å, and V = 3737.6(2) Å3. The structure was refined using the Rietveld method. The atomic positions were refined in the isotropic approximation, with soft constraints on Mo–O distances and O–Mo–O bond angles. The crystal structure constitutes a 3D scaffold comprising PbO6 and ZrO6 octahedrons and MoO4 tetrahedrons sharing oxygen vertices. The thermal expansion of K5Pb0.5Zr1.5(MoO4)6 was studied via high-temperature X-ray powder diffraction. The calculated thermal expansion coefficients along both crystallographic axes remain positive over the entire temperature range. In this case, the value of αa remains constant, while that of αc increases with rising temperature. The obtained ternary molybdate belongs to materials with high thermal expansion (αV = 60×10-6 °С-1). The significant anisotropy in the crystallographic direction c can be attributed to the soft K–O and Pb-O bonds. The electrical conductivity of K5Pb0.5Zr1.5(MoO4)6 was studied via impedance spectroscopy within the temperature range of 30–500 °С; at 500 °С, the conductivity amounted to 0.7×10-4 S/cm, with Ea = 0.59 eV.
Reconstructing volatile evolution in melts using zircon-hosted apatite inclusions: Implications for use of apatite as a fertility indicator

Published: January 2025

Abstract
Porphyry Cu deposits are genetically associated with oxidized, hydrous, and volatile-rich (e.g., Cl, S) magmas. Magmatic volatiles are critical to the fertility of magmas associated with porphyry Cu mineralization. A continuous volatile record from volatile-undersaturation to fluid-saturation in the magma reservoir is significant for understanding the genesis of porphyry Cu deposits. Apatite serves as a reliable recorder of the magmatic-hydrothermal history in porphyry Cu systems, with its volatile evolution providing an effective method for identifying the occurrence of volatile saturation. In this study, we measure the compositions of apatites occurring as inclusions in various minerals, including zircons, in both fresh and altered pre-mineralization monzogranite and inter-mineralization monzogranite porphyry from the Zhunuo porphyry Cu deposit in the Gangdese belt, southern Tibet. Cathodoluminescence and composition reveal significant differences between unaltered and hydrothermally altered apatites. Primary magmatic apatites exhibit homogeneous yellow to brown luminescence, whereas hydrothermally altered apatites display a wide range of distinctive luminescence colors (e.g., dull yellow-green, green, and gray). Furthermore, primary magmatic apatites show a significantly higher Mn/Fe ratio (&gt;1.5) and rare earth element (REE) plus Y contents (&gt;4500 ppm) compared to hydrothermally altered apatites (Mn/Fe &lt; 1.5, REE+Y &lt; 4500 ppm). Zircon-hosted apatite inclusions demonstrate decreasing XCl/XOH ratios (∼1.0–0.2) with increasing XF/XOH (2–11) and XF/XCl (4–48) ratios, indicating volatile exsolution during or prior to zircon crystallization in the magma chamber. Phenocryst-hosted apatite inclusions and groundmass apatite crystals have comparable volatile compositions, characterized by higher XF/XOH (5–25) and XF/XCl (15–75) but lower XCl/XOH (mostly &lt; 0.3) compared to zircon-hosted apatites. We infer that the phenocryst-hosted apatite inclusions may have formed during/after fluid exsolution, or may not escape re-equilibration with the residual melt due to the less robust nature of their silicate hosts The calculated melt Cl contents, derived from low-XF/XCl zircon-hosted apatites in the monzogranite porphyry are 0.17 ± 0.06 wt%, overlapping with those of the monzogranite (0.12 ± 0.04 wt%). The relatively high Cl contents of primary ore-forming magmas likely facilitate effective Cu extraction from the melt to hydrothermal fluid. Our study highlights that apatite-in-zircon is more valuable than non-zircon hosted apatite grains for reconstructing melt volatile evolution and could be a better Cu-fertility indicator for porphyry Cu mineralization than other forms of apatite.

Authors: Möllmann Henriette Louise , Alhammadi Eman , Boulghoudan Soufian , Kuhlmann Julian , Mevissen Anica , Olbrich Philipp , Rahm Louisa , Frohnhofen Helmut 
Published: January 2025

Background
An aging population in combination with more gentle and less stressful surgical procedures leads to an increased number of operations on older patients. This collectively raises novel challenges due to higher age heavily impacting treatment. A major problem, emerging in up to 50% of cases, is perioperative delirium. It is thus vital to understand whether and which existing geriatric assessments are capable of reliably identifying risk factors, how high the incidence of delirium is, and whether the resulting management of these risk factors might lead to a reduced incidence of delirium.

Objective
This study aimed to determine the frequency and severity of geriatric medical problems in elective patients of the Clinics of Oral and Maxillofacial Surgery, Vascular Surgery, and Orthopedics, General Surgery, and Trauma Surgery, revealing associations with the incidence of perioperative delirium regarding potential risk factors, and recording the long-term effects of geriatric problems and any perioperative delirium that might have developed later the patient’s life.

Methods
We performed both pre- and postoperative assessments in patients of 4 different surgical departments who are older than 70 years. Patient-validated screening instruments will be used to identify risk factors. A geriatric assessment with the content of basal and instrumental activities of daily living (basal activities of daily living [Katz index], instrumental activities of daily living [Lawton and Brody score], cognition [6-item screener and clock drawing test], mobility [de Morton Mobility Index and Sit-to-Stand test], sleep [Pittsburgh Sleep Quality Index and Insomnia Severity Index/STOP-BANG], drug therapy [polypharmacy and quality of medication, Fit For The Aged classification, and anticholinergic burden score], and pain assessment and delirium risk (Delirium Risk Assessment Tool) will be performed. Any medical problems detected will be treated according to current standards, and no intervention is planned as part of the study. In addition, a telephone follow-up will be performed 3, 6, and 12 months after discharge.

Results
Recruitment started in August 2022, with 421 patients already recruited at the time of submission. Initial analyses of the data are to be published at the end of 2024 or the beginning of 2025.

Conclusions
In the current study, we investigate whether the risk factors addressed in the assessment are associated with an increase in the delirium rate. The aim is then to reduce this comprehensive assessment to the central aspects to be able to conduct targeted and efficient risk screening.

An Assessment of Privacy Concerns and Willingness to Share Real-World Data Among an Aging Population in the United States: Survey Study (Preprint)
Authors: Hendricks-Sturrup Rachele , Lu Christine Y. 
Published: January 2025

BACKGROUND

Biomedical innovation is often dependent on individuals’ expressed willingness to donate health data generated in real world settings (real-world data or RWD). Yet, unresolved ethical, legal, and social implications (ELSI) concerns (i.e., genetic privacy and nondiscrimination) exist alongside aging populations’ willingness to share RWD with researchers.

OBJECTIVE

To describe an aging populations’ willingness to donate health data today and post-mortem with researchers and summarize their ELSI-related concerns.

METHODS

We surveyed participants aged 51 years and older to assess their willingness to donate various types (direct-to-consumer genetic testing, fitness tracking, prescription history, and electronic medical record data) and quantities (none, some, all) of their health-related RWD today and post-mortem to researchers. Descriptive statistical analyses were conducted using Microsoft Excel and manual queries (single layer, bottom-up topic modeling) to quantify, organize, and categorize, from free-text survey responses, comments/concerns into themes and provide illuminating quotes.

RESULTS

Among 199 survey respondents, most were willing to donate some health data, though more participants were willing to donate health data post-mortem versus today (86% and 55%, respectively). More participants were willing to donate electronic medical record and prescription history data today versus post-mortem (67% versus 48% and 62% versus 52%, respectively). In comparison, participants were less willing to donate genetic and fitness tracker data (58% versus 38% and 55% versus 38%, respectively, today versus post-mortem). Four themes were identified across 96 comments/concerns expressed among participants about sharing data today and in the future: data security, breach, misuse, or mishandling and unintended consequences (42%); privacy and safety from governmental or other institutional discrimination or harm (32%); high selectivity or absolute preference in data sharing (19%); perceived risks associated with sharing data with researchers (7%).

CONCLUSIONS

Certain privacy and nondiscrimination legal protection gaps remain; certain entities are exempt from protections afforded under laws that include but are not limited to the Health Insurance Portability and Accountability Act and Genetic Information Nondiscrimination Act in the United States. This routinely creates real and/or perceived risks for aging populations who may rely on access to and use of insurance benefits and other important aspects of daily life. As our findings substantiate this fact, work is needed to ensure aging populations have access to trustworthy data sharing mechanisms pre- and post-mortem.

Ensemble Learning Layer for Wayang Recognition using CNN-based ResNet-50 and LSTM
Authors: Irawan Candra , Rachmawanto Eko Hari , Hadi Heru Pramono 
Published: January 2025

Wayang is commonly used to tell epic stories of Mahabharata and Ramayana, as well as local legends and myths. There are various types of wayang, such as wayang kulit (made of buffalo or goat leather), wayang golek (made of wood), and wayang klithik (combination of leather and wood). Although it indicates cultural richness, such diversity also makes it difficult for the general public to identify the character of wayang they are seeing because each type has unique characteristics and details. Recognizing wayang characters is a challenging task due to their intricate designs and subtle variations. This research addresses this problem by leveraging machine learning technology, specifically CNN-based classification methods, to accurately identify wayang characters. This study proposed a novel method that integrates ResNet-50 transfer learning with LSTM, enhancing the model's ability to capture both spatial and sequential features of wayang images. The proposed model achieved an impressive accuracy of 97.92%, with precision, recall, and F1-scores all reaching 100%. Despite the extended training time of 188 minutes and 21 seconds, the results demonstrate the model's superior performance. This advancement can significantly aid in the preservation and educational dissemination of Indonesian cultural heritage. Future research can focus on optimizing the training process to reduce the time while maintaining or even improving the accuracy, potentially expanding the model's application scope and effectiveness.

Action vs. Reaction
Authors: Jacob Anderskov  
Published: January 2025

"Action versus Reaction - Artistic encounters with an aesthetic otherness", was a research project undertaken at the Rhythmic Music Conservatory in Copenhagen in 2015-2016. The primary artistic output of the project is the album ”Resonance”, released on Sundance Music in September 2016.
My ensemble Resonance (previously known as ” Strings, Percussion & Piano”) consists of 3 string players as well as Peter Bruun on drums and myself on piano. The string players all have a background in European classical music and (composed) new music, whereas Peter and I originally came out of improvised music, jazz and its neighbouring regions. In this ensemble, we have been dealing with artistic encounters between our different aesthetics backgrounds for several years. I have realized that my primary curiosity orbits around the questions:
1)	How can all members of a cross-genre ensemble stay true to their own musical intuition, developed through decades of full immersion?
2)	How can these confident artists then transcend their notion of themselves and meet anew in an aesthetic field different from their respective origins?

In 2018, Jacob Anderskov was nominated for the Nordic Council Music Price for the album Resonance.
Cultural Identity as One of the Regulators of Legal Relationships in a Contemporary Russian Family
Authors: Alekhina E. S. , Palamarchuk E. A. 
Published: January 2025

Introduction. Investigation of the legal activity in the frame of the family relationships seems to be especially relevant in the period of global instability and Westernization. The analysis of the present-day approaches to formation of the family relationships has revealed the dualism in legal universality and cultural identity in the different communities: although the vector of the current state policy of the Russian Federation aims at strengthening the traditional family values, the internal life of a contemporary Russian family often does not fit into this conceptual framework and develops in the direction of the sociocultural alterations of the society, thus, revealing the gaps in the existing legislation. The aim of this paper is to distinguish the aspect of cultural identity as one of the fundamental legal regulators of family relationships for improving the legal system in this field.Materials and Methods. The leading method used in the research was a comparative approach based on comparing and analysing the legal and cultural family values in Russia and abroad, as well as on contrasting the traditional and modernist concepts of a family ideal. Additionally, application of the general scientific and specific scientific methods (systematization, historical method, abstract-logical method, axiological and legalistic approaches) allowed for a deeper investigation of the features of the family relationship development in the frame of a certain culture.Results. On the example of the cultural specifics of the different states, the fundamental components forming the institution of a family and regulating the internal family relationships were identified, where the dominating ones were the socio-cultural norms, moral and ethical values and religious views. The analysis of the regulatory documents and relevant research papers enabled finding out the inconsistencies between the concept of supporting the traditional family relationships and the cultural values of the society. Having defined the boundaries of the cultural and legal regulators’ impact, we propose to implement the positive legal methods as a replacement to the radical autocratic approaches for achieving the cultural and legal consensus and developing the legal consciousness of a family.Discussion and Conclusion. The multifacetedness of the cultural code of a nation requires making changes to the state government and legislative bodies. Therefore, the forward-looking research concepts in the field of the family legal relationships should aim at uniting the traditional legal and cultural approaches to formation of the family values with the modernized ideas of the civil society.
Structure-guided Generative Adversarial Network for Image Inpainting
Authors: Liang Huan , Zhao Li , Cao Lei 
Published: January 2025

Abstract
Generative Adversarial Network based image inpainting algorithms often make errors when filling arbitrary masked areas because all input pixels are treated as effective pixels during convolutional operations. To resolve this matter, we present a novel solution: an image inpainting algorithm that utilizes gated convolutions within the residual blocks of the network. By incorporating gated convolutions instead of traditional convolutions, our algorithm effectively learns and captures the relationship between the known regions and the masked regions. The algorithm utilizes a two-stage generative adversarial restoration network, where the structure and texture restoration are performed sequentially. Specifically, the structural information of the known region in the damaged image is detected using an edge detection algorithm. Subsequently, the edges of the masked area are combined with the color and texture information of the known region for structure restoration. Finally, the complete structure and the image to be restored are fed into the texture restoration network for texture restoration, yielding the complete image output. During network training, a spectral normalization Markovian discriminator is employed to address the slow weight changes during iteration, thereby increasing convergence speed and model accuracy. Based on the Places2 dataset, our experimental findings indicate that our algorithm surpasses existing two-stage restoration algorithms in terms of improving peak signal-to-noise ratio and structural similarity. Specifically, our proposed algorithm achieves a 4.3% enhancement in peak signal-to-noise ratio and a 3.7% improvement in structural similarity when restoring images with various shapes and sizes of damaged areas. Additionally, it produces noticeable visual enhancements, further validating its effectiveness.
Nystagmus Detection Method Based on Gating Mechanism and Attention Mechanism
Authors: Hou Maolin 
Published: January 2025

Abstract
In this paper, a new model based on the combination of improved LSTM and self-attention mechanism is studied for the detection of nystagmus caused by vestibular illusion in pilots during flight. An efficient and robust nystagmus detection method was proposed by constructing experimental simulation scenarios and collecting and analyzing pilot eye movement data. The improved LSTM model enhances the ability of capturing the medium and long term dependence of the ocular shock sequence by adding a gating unit, and the introduction of self-attention mechanism further improves the analytical accuracy of the model for complex eye movement sequences. The experimental results show that the model has excellent performance in accuracy, recall rate and F1 score, which is significantly better than the traditional model, providing a new technical means for the detection of vestibular illusion.The LSTM-GRU-Attention model has been experimentally verified to perform best in accuracy, recall, and F1 score, reaching 095, 0.91, and 0.93 respectively, indicating that the outperforms the other two models in overall classification performance, positive sample recognition ability, and balance between accuracy and recall.
