Extending the study of playfulness in romantic life: Analyzing associations with attachment and jealousy in same-gender and opposite-gender couples
Authors: Brauer Kay , Sendatzki Rebekka , Proyer René T.
Published: August 2024

Adult playfulness describes individual differences in (re)framing situations so that they are experienced as entertaining, and/or interesting, and/or intellectually stimulating. There is increasing interest in its role for romantic life. Using the OLIW model of playfulness, we localized its facets Other-directed, Lighthearted, Intellectual, and Whimsical playfulness into systems of attachment styles and romantic jealousy. We analyzed data of 332 mixed-gender and 139 same-gender couples (Ntotal = 942). We found no robust mean differences between same-gender and mixed-gender couples (exception: same-gender couples are lower in emotional jealousy). Actor-Partner Interdependence Model analyses showed that Other-directed, Lighthearted, and Intellectual playfulness yielded negative relations to attachment insecurities in actors, but no partner effects. For jealousy, all types of playfulness related negatively to emotional jealousy, but Whimsical playfulness showed positive inclinations to cognitive and behavioral jealousy in actors. Partners reported greater cognitive jealousy when their partner was high in Lighthearted, whereas partners from Whimsical high scorers reported lower emotional jealousy. The findings are invariant between same-gender and mixed-gender couples. Our study extends the knowledge on how playfulness relates to experiences in close relationships in mixed-gender and same-gender couples. We discuss implications (e.g., Signal Theory of Playfulness) and future directions.

Published: August 2024

Strength, ductility, and failure properties of metals are tailored by plastic deformation routes. Predicting these properties requires modeling of the structural dynamics and stress evolution taking place on several length scales. Progress has been hampered by a lack of representative 3D experimental data at industrially relevant degrees of deformation. We present an X-ray imaging based 3D mapping of an aluminum polycrystal deformed to the ultimate tensile strength (32% elongation). The extensive dataset reveals significant intra-grain stress variations (36 MPa) up to at least half of the inter-grain variations (76 MPa), which are dominated by grain orientation effects. Local intra-grain stress concentrations are candidates for damage nucleation. Such data are important for models of structure-property relations and damage.

Authors: Sharafudeen Misaj , S S Vinod Chandra , J. Andrew , Sei Yuichi
Published: August 2024

An automated speaker verification system uses the process of speech recognition to verify the identity of a user and block illicit access. Logical access attacks are efforts to obtain access to a system by tampering with its algorithms or data, or by circumventing security mechanisms. DeepFake attacks are a form of logical access threats that employs artificial intelligence to produce highly realistic audio clips of human voice, that may be used to circumvent vocal authentication systems. This paper presents a framework for the detection of Logical Access and DeepFake audio spoofings by integrating audio file components and time-frequency representation spectrograms into a lower-dimensional space using sequential prediction models. Bidirectional-LSTM trained on the bonafide class generates significant one-dimensional features for both classes. The feature set is then standardized to a fixed set using a novel Bags of Auditory Bites (BoAB) feature standardizing algorithm. The Extreme Learning Machine maps the feature space to predictions that differentiate between genuine and spoofed speeches. The framework is evaluated using the ASVspoof 2021 dataset, a comprehensive collection of audio recordings designed for evaluating the strength of speaker verification systems against spoofing attacks. It achieves favorable results on synthesized DeepFake attacks with an Equal Error Rate (EER) of 1.18% in the most optimal setting. Logical Access attacks were more challenging to detect at an EER of 12.22%. Compared to the state-of-the-arts in the ASVspoof2021 dataset, the proposed method notably improves EER for DeepFake attacks by an improvement rate of 95.16%.

Published: August 2024

Ultra-low-power consumption and high-speed integrated switches are highly desirable for future data centers and high-performance optical computers. In this study, we proposed an ultra-low-power consumption silicon electro-optic switch based on photonic crystal nanobeam cavities on a foundry platform. The proposed switch showed an ultra-low static-tuning power of 0.10 mW and a calculated dynamic switching power of 6.34 fJ/bit, with a compact footprint of 18 μm × 200 μm. Additionally, a 136-Gb/s four-level pulse amplitude modulation signal transmission experiment was carried out to verify the capability of the proposed electro-optic switch to support high-speed data transmission. The proposed device has the lowest static-tuning power consumption among silicon electro-optic switches and the highest data transmission rate. The results demonstrate the potential applications of this switch in high-performance optical computers, data center interconnects, optical neural networks, and programmable photonic circuits.

PDCD10 promotes the tumor-supporting functions of TGF-β in pancreatic cancer
Authors: Zhou Qianwen , Breitkopf-Heinlein Katja , Gaitantzi Haristi , Birgin Emrullah , Reissfelder Christoph , Rahbari Nuh N.
Published: August 2024

The progression of pancreatic ductal adenocarcinoma (PDAC) is significantly affected by transforming growth factor (TGF)-β but targeting TGF-β can also compromize physiological effects in patients.

Our study examined the functions of the ubiquitously expressed protein, PDCD10, as a modulator of TGF-β signaling in PDAC. Using in silico analyses we found that in patient samples, PDCD10 is significantly higher expressed in PDAC tumor tissue compared with normal pancreas and it is highly correlated with reduced survival. We created stable KO’s of PDCD10 in two PDAC lines, PaTu 8902 (SMAD4 +/+) and PaTu 8988t (SMAD4 -/-), and found that KO lines are more sensitive to 5-FU and Gemcitabine treatment than their wild-type counterparts. Performing viability and wound closure assays we further found that PDCD10 promotes cell survival and proliferation by enhancing specifically the mitogenic functions of TGF-β. The molecular mechanism underlying this effect was further investigated using Western blots and with primary organoid lines derived from patient PDAC tissue samples. The data imply that PDCD10 mediates an increase in p-ERK through a non-SMAD4 pathway, leading to EMT promotion. Furthermore, PDCD10 facilitates deactivation of RB via a SMAD4-dependent pathway, thereby counter-acting the anti-proliferative actions of TGF-β. By performing proximity ligation assays (PLA) we found that PDCD10 associates with the kinase MST4, translocates it intracellularly and thereby facilitates phosphorylations of RB and ERK1/2.

Our study indicates that PDCD10 promotes the proliferative function and EMT induction of TGF-β in pancreatic cancer cells. Therefore, targeting PDCD10 in PDAC patients could represent a promising new strategy to optimize TGF-β targeted therapies.

This study aimed to investigate the effect of different feeding regimens in a long-term period on the reproductive performance of young Garut rams. Thirty individuals with an average body weight of 20.12 kg were randomly assigned to two groups. The CF group received 70% concentrate and 30% Pennisetum purpureum, while the FT group was provided with 70% Pennisetum purpureum and 30% tofu waste. The treatments were isoprotein and isoenergy. Rams were fed the same diet consistently starting from weaning age at 2 months. Semen and blood samples were collected at the age of puberty, around 9-10 months old. The results showed that different feeding regimens did not affect the total dry matter intake of young rams or their final body weight. Blood glucose was similar for both groups. Feeding CF resulted in a significantly higher (P < 0.05) blood cholesterol. Sperm viability and intact plasm membrane were highest (P < 0.05) in the CF group compared to the FT group. Semen volume and testosterone were higher (P < 0.05) in the group fed FT compared to the CF group. In conclusion, high concentrates have implications for better sperm membrane and survival, while a higher proportion of forage with tofu waste increases semen volume which is associated with more frozen semen production.

Authors: Kalandarov Palvan , Zhunussov Kanat , Kassimov Abdurazak , Baibolov Bagzhan , Junussov Nuridin , Kaliyeva Kazima
Published: August 2024

This work considers the ozonation of surface water as an effective method for treating water to eliminate microorganisms and remove organic pollutants. However, the ozonation process changes the physicochemical properties of water, notably the pH level. Changes in pH can significantly affect the efficiency of water purification and potentially impact the condition of aquatic ecosystems when the treated water is discharged. This paper presents the results of experimental studies evaluating the dynamics of pH changes in various water bodies (distilled, ionized, tap, and river water) during the ozonation process. Special attention is given to the presence of heavy metal salts in water, which can catalyze the decomposition of ozone and intensify changes in pH. The study shows that ozonating surface water can lead to a decrease in pH, which may necessitate subsequent pH adjustments to maintain optimal levels for various uses of the treated water. The work is of practical significance for improving the efficiency of ozone use in industrial and municipal services and for water purification processes.

Drug (substance) abuse is a complex issue with impacts on student wellbeing, performance, and potential. The lack of targeted preventive strategies addressing this critical societal challenge underscores the need for an in-depth investigation into the prevalence and drivers of drug abuse specifically among architecture students. This study investigates the prevalence, motivations and attitudes surrounding substance abuse among 304 architecture students across 5 universities in Enugu, Nigeria. A quantitative research approach was utilized, and primary data was gathered for evaluation through the use of well-structured Questionnaires distribute to students in the study area. Findings reveal concerning 90% alcohol/energy drink usage rates and frequent dependence coping with project deadlines, indicating potentially normalized on-campus misuse. Key triggers include peer influences (42%), performance enhancement (14.5%), enjoyment/ experimentation (19.5%) and self-medication (3%). However, 80% recognize abuse risks, evidencing complex psychosocial dynamics. The study mitigation recommendations centered on awareness creation, policy reforms, faculty training and peer support systems – are not punitive sanctions. It concludes that tight-knit studio cultures seemingly propagate usage; transformative educational strategies addressing high-stress design education realities can restrict enablement.

Irrigation, groundwater and subsoil waters (soil solution) in the irrigated lands of the Ferghana Valley are integral parts of a chain in the formation, movement and accumulation of salts in the soil, and it is important to study them together in solving reclamation problems. In the process of soil formation, especially in the formation of optimal groundwater regime and balance in the conditions of valley irri-gated soils, the role of subsoil waters is particularly large, has a multifaceted effect on the formation of saline soils, functions as the main source of salt in the soil in a certain situation; serves as a means of col-lecting (cumulating) dissolved salts and expelling them from the territory of irrigated and salt-washed areas (by means of ditches) in the second situation. The mechanical composition of soils plays an impor-tant role in the movement, redistribution and accumulation of dissolved salts in the vertical and horizontal directions along the soil profile.

Possibilities of organizing microclimate systems on the basis of ultrasonic mist generator
Authors: Radkevich Maria , Ashirova Olga , Shipilova Kamila
Published: August 2024

The increase in average annual and summer temperatures in cities adversely affects the health of residents. To address the effects of climate change on urban populations, outdoor microclimate systems that spray liquid droplets are utilized. However, these systems have significant drawbacks, including high water usage and limited efficiency in reducing temperatures. In areas facing water scarcity, such as many Asian countries, microclimate systems that utilise ultrasonic mist generators appear to be a more viable option. This article presents a study examining the operation of a physical model of a climate system incorporating ultrasonic mist generators. Experimental data indicate that the cooling effect is evident within the first 2-3 minutes of system operation, with a temperature decrease rate of 0.7 oC/min observed. A mathematical model has been derived that describes the process of temperature reduction in the unit operation zone. The model is based on a hyperbolic function.

Background: Schistosoma japonicum (S. japonicum) is the main species of Schistosoma prevalent in China. Myeloid-derived suppressor cells (MDSCs) are important immunoregulatory cells and generally expand in parasite infection, but there is little research relating to MDSCs in Schistosoma infection. Methods: Fifty-six S. japonicum-infected patients were included in this study. MDSCs and percentages and absolute cell numbers of lymphocyte subsets, including CD3+ T cells, CD4+ T cells, CD8+ T cells, B cells and natural killer (NK) cells were detected using flow cytometry. The degree of liver fibrosis was determined using color Doppler ultrasound. Results: Patients infected with S. japonicum had a much higher percentage of MDSCs among peripheral blood mononuclear cells (PBMCs) than the healthy control. Regarding subpopulations of MDSCs, the percentage of granulocytic myeloid-derived suppressor cells (G-MDSCs) was clearly increased. Correlation analysis showed that the absolute cell counts of T-cell subsets correlated negatively with the percentages of MDSCs and G-MDSCs among PBMCs. The percentage of G-MDSCs in PBMCs was also significantly higher in patients with liver fibrosis diagnosed by color doppler ultrasound (grade > 0), and the percentage of G-MDSCs in PBMCs and liver fibrosis grading based on ultrasound showed a positive correlation. Conclusion: S. japonicum infection contributes to an increase in MDSCs, especially G-MDSCs, whose proliferation may inhibit the number of CD4+ T cells in peripheral blood. Meanwhile, there is a close relationship between proliferation of G-MDSCs and liver fibrosis in S. japonicum-infected patients.
A generalization for ultradiscrete limit cycles in a certain type of max-plus dynamical systems
Authors: Ohmori Shousuke , Yamazaki Yoshihiro
Published: August 2024

Dynamical properties of a generalized max-plus model for ultradiscrete limit cycles are investigated. This model includes both the negative feedback model and the Sel’kov model. It exhibits the Neimark–Sacker bifurcation, and possesses stable and unstable ultradiscrete limit cycles. The number of discrete states in the limit cycles can be analytically determined and its approximate relation is proposed. Additionally, relationship between the max-plus model and the two-dimensional normal form of the border collision bifurcation is discussed.
Time-dependent personalized PageRank for temporal networks: Discrete and continuous scales
Authors: Aleja David , Flores Julio , Primo Eva , Romance Miguel
Published: August 2024

In this paper, we explore the PageRank of temporal networks (networks that evolve with time) with time-dependent personalization vectors. We consider both continuous and discrete time intervals and show that the PageRank of a continuous-temporal network can be nicely estimated by the PageRanks of the discrete-temporal networks arising after sampling. Additionally, precise boundaries are given for the estimated influence of the personalization vector on the ranking of a particular node. All ingredients in the classic PageRank definition, namely, the normalized matrix collecting the topology of the network, the damping factor, and the personalization vector are allowed, to the best of our knowledge, for the first time in the literature to vary independently with time. The theoretical results are illustrated by means of some real and synthetic examples.
Restoration of misty images based on wavelet transform and atmospheric scattering model
Authors: Liu Pengcheng
Published: August 2024

In conditions of low visibility, the scattering effect of atmospheric particles can result in images captured by cameras exhibiting a number of problems, including reduced contrast, color distortion, and blurred details. These issues can have a significant impact on the clarity and recognition of the images. In response to these issues, this study combines atmospheric scattering models with wavelet transform, introduces non-blind deconvolution algorithms and, finally, designs a special gamma correction function to ultimately develop a new foggy image restoration model. The relevant outcomes showed that when the dehazing model processed most image samples, its edge preservation was mainly concentrated in a relatively high range, namely [0.80, 0.96]. From the perspective of the structural similarity index, the discrete wavelet transform achieved the highest value of 0.8264. In addition, the peak signal-to-noise ratio of the improved gamma correction function was 18.346. The proposed algorithm for restoring foggy images has the advantages of high clarity, strong color restoration ability, and fast restoration speed, providing more reliable and efficient image data support for applications in related fields.

To control and optimize the power of the SPARC tokamak, we require information on the total radiated power of the plasma and its 2D and 3D spatial distribution. The SPARC bolometry diagnostic is being designed and built to measure the radiated power for controlling power balance, investigating the dissipation capabilities of various divertor concepts, and measuring the efficacy of the disruption thermal load mitigation. Proven resistive bolometer sensor technology will be used, with 248 lines of sight integrated into pinhole cameras in 20 different locations. This diversity of views will allow the bolometers to view the core, divertor, and particularly X-points of the plasma with high resolution. 14 of these camera locations are dedicated to 2D equilibrium radiated power, while the remaining six locations are designed to measure 3D radiated energy during disruptions. The bolometer sensor holders, pinhole camera boxes, and cabling have been designed to survive the high neutron flux (but low fluence) and up to 400 °C temperatures seen during operation and vacuum bake. The resistive bolometer sensors use Au absorbers with an Al heat conduction layer and C anti-reflective layer. These sensor chips are wire-bonded to an AlN circuit board, both of which are held inside a custom AlN and stainless steel bolometer holder. Design and optimization of the pinhole camera lines of sight are performed using Cherab. This work details the current state of the design of the SPARC bolometry diagnostic and its interfaces, as well as ongoing work to validate the design.
