The sense of groundedness occurs when tourists connect to the geography, humanity, and history of destination. Little is known about how technology, marketing, and tourism resources can be combined to enrich the authenticity of the virtual tourism experience. This study explores the main characteristics of groundedness in cultural tourism to address this research gap. It develops and validates the scale for measuring tourism experience based on live streaming technology. The findings also reveal groundedness as a driver of tourists’ willingness and behavior to participate. The study theoretically promotes the development of groundedness and the emerging research on digital cultural tourism marketing. Meanwhile, the study results provide stakeholders with an attractive and implementable tourism perceptual experience, groundedness, implying references for overall sustainable destination development.

Live Motile Sperm Sorting Device Improves Embryo Aneuploidy: A Retrospective Cohort Study

Background: Conventional sperm selection methods, involving centrifugation, exert a detrimental effect on sperm DNA integrity due to mechanical stress. The recent noninvasive sperm selection device, CA0, based on live sperm sorting technology, facilitates the retrieval of highly motile sperm and minimizes sperm DNA fragmentation (SDF). This study was to investigate the impact of various sperm separation methods, with and without centrifugation, on embryo ploidy status. Methods: The retrospective study comprised 82 intracytoplasmic sperm injection (ICSI) cycles involving preimplantation genetic testing for aneuploidy (PGT-A) cases, with a focus on recruiting egg donation cycles to thoroughly investigate the impact of male factors. Two populations are classified based on semen quality: normozoospermic ([Formula: see text] = 33) and non-normozoospermic ([Formula: see text] = 49). Subjects were allocated to either swim-up (SU) or CA0. Preimplantation genetic testing results were recorded. Results: When comparing male characteristics between subgroups, no significant differences were observed except for a lower normal morphology rate in the CA0 group compared to SU (SU: 3 [3–4] vs. CA0: 2 [2–2.8], [Formula: see text] < 0.0001) in the non-normozoospermic cohort. There were no differences in female factors such as age and mature oocyte count (MII) number between subgroups, indicating that this model is ideal for assessing the impact of male factors on clinical outcomes. In the normozoospermic cohort, euploidy rates were similar between SU and CA0 (SU: 71.9% vs. CA0: 64.2%). However, in the non-normozoospermic cohort, CA0 showed a significantly higher euploidy rate compared to SU (SU: 53.6% vs. CA0: 74.2%) and a lower aneuploidy rate (SU: 37.1% vs. CA0: 25.8%). Additionally, CA0 minimized the incidence of mosaic embryos, whereas a mosaicism rate of 9.3% was observed with SU. This trend highlights CA0’s distinct advantage in optimizing outcomes for non-normozoospermic cases. Conclusions: CA0 is a reliable intervention to optimize paternal genetic quality before assisted insemination, thereafter effectively reducing the incidence of embryo aneuploidy associated with male factors.

Research on live detection technology of distribution network cable insulation deterioration state based on harmonic components

AbstractDue to the limitations imposed by urban power grid outages for maintenance, on‐line harmonic current detection technology for distribution network cables is expected to become an effective supplement to traditional offline diagnostic methods, enhancing the real‐time diagnosis of distribution network cable insulation conditions. This study established a 10 kV distribution network cable test platform and prepared typical defective cables subjected to moisture and long‐term thermal aging. Using COMSOL finite element electromagnetic simulation, the magnetic flux evolution laws of the cable insulation under typical defects were obtained. Experimental tests provided the harmonic current characteristics and statistical features of cables with typical defects. Based on these data, a method for analysing the degradation degree of distribution network cables was constructed using least absolute shrinkage and selection operator (LASSO) regression analysis. Furthermore, a defect‐type identification method based on cluster analysis was proposed. Results indicate that the odd harmonics and the 4th harmonic of the distribution network cable's harmonic current are closely related to the cable's degradation state. A model integrating principal component analysis (PCA) data dimensionality reduction and expectation‐maximization clustering analysis achieved a recognition accuracy of up to 75.64% in distinguishing between moisture‐affected and normal cable states. The proposed on‐line detection and evaluation methods can effectively identify high‐risk cables with latent defects.

Humanized virtual anchors establish trust relationships and stimulate purchase intentions through rich expressions and actions; Personalized and customized design enhances the attractiveness and sense of identity of virtual anchors. Finally, regarding the application of enterprises in the field of virtual anchors, this article proposes anthropomorphic design, personalized image, and cultural adaptability strategies to improve the commercial efficiency and brand image of virtual anchors.

How to enhance consumers’ purchase intention in live commerce? An affordance perspective and the moderating role of age

Live commerce is a novel form of social commerce characterized by real-time interaction and synchronous visualization. Drawing upon affordance theory and the affective-cognitive framework, we propose a comprehensive research model that integrates three key dimensions of affordances of live commerce technology, namely utilitarian (visibility), social (social presence, interactivity, self-presentation), and hedonic affordances (entertainment), together with consumers’ cognitive and affective states (perceived diagnosticity and psychological distance). Furthermore, we explore age as an important contingency factor in understanding consumers’ purchase intention in live commerce. We collect data from 353 consumers who have live shopping experiences in China and analyze the research model with the structural equation model approach. Results indicate that visibility, social presence, and interactivity positively contribute to perceived diagnosticity, whereas entertainment and the three social affordances reduce psychological distance. Notably, the influence of perceived diagnosticity on purchase intention is more pronounced among older consumers, whereas the impact of psychological distance on purchase intention is stronger among younger consumers. This study not only advances the understanding of affordance theory within live commerce contexts but also offers practical insights for streamers and live commerce platforms.

P-009 Impact of sperm preparation methods on embryo development rate and embryo ploidy status: ICSI egg donation as a model

Abstract Study question Do different sperm separation techniques result in distinguishable contributions to embryo development rates and ploidy status? Summary answer CA0 sperm separation device, devoid of centrifugation, yielded a higher euploidy rate than conventional swim-up (50% vs. 74%, p = 0.02), notably observed in abnormozoospermic cases. What is known already Sperm DNA fragmentation (SDF) emerges as a key paternal risk factor associated with embryo aneuploidy, increasing the risk of ART failures. Factors like advanced male age, prolonged ejaculatory abstinence, and the detrimental effects of centrifugation during sperm separation jeopardize sperm DNA integrity. A recent centrifugation-free sperm separation device (CA0), employing live sperm sorting technology, exhibits efficiency in producing highly motile sperm with minimized SDF. This retrospective cohort study solely focusing on ICSI egg donation cycles to assess the influence of sperm separation methods (conventional swim-up vs. CA0) on early embryo development, and embryo ploidy. Study design, size, duration This retrospective study included 83 couples who underwent ICSI egg donation cycles at Chachava Clinic, Tbilisi, Georgia. Thirty-three semen specimens were processed using conventional swim-up (SU) and 427 Mii were inseminated. Forty-four semen samples were separated by CA0 and 519 Mii were inseminated. Clinical outcome measures included fertilization rate (number of 2PN over number of inseminated oocyte), good embryo rate (embryo number with more than 8 cells over inseminated oocyte), and euploidy rate using PGT-A. Participants/materials, setting, methods Male age and basic semen parameters via CASA (CEROS II, Hamilton-Thorne) were recorded. SU involved layering 1 mL neat semen to 1.2 mL HTF medium, inclining the tube at 45° for 60 min at 37 °C, collecting 1 mL uppermost, adding 2 mL HTF for centrifugation at 500×g for 5 min, and resuspending sperm pellet with 0.5 mL HTF. Semen samples were sorted using LensHooke® CA0 device following the manufacturer’s instructions. Main results and the role of chance In comparing demographic characteristics between SU and CA0 arms, CA0 exhibited higher median total motility (SU: 40% vs. CA0: 54%, p = 0.02), with no significant differences in female age and Mii oocyte count. This study assessed the impact of sperm separation methods on early embryo development, finding no significant differences in fertilization rate (SU: 79% vs. CA0: 77%) and good embryo rate (SU: 64% vs. CA0: 62%). However, CA0 demonstrated a significantly higher euploidy rate than SU (SU: 59% vs. CA0: 69%, p = 0.03). Further analysis within subpopulations, including normozoospermic and asthenozoospermic (total motility <40%), revealed equivalent euploidy rates between SU and CA0 for normospermic specimens (SU: 66% vs. CA0: 68%). However, a significant differentiation in euploidy rate emerged for asthenozoospermic cases (SU: 59% vs. CA0: 74%, p = 0.02). Specifically, comparing outcomes in normozoospermic, a significant reduction was observed in asthenozoospermic cases using SU (66% vs. 50%, p = 0.02), whereas CA0 provided improved euploidy rates regardless of semen quality (68% for normozoospermic and 74% for asthenozoospermic). In conclusion, this study suggests that the non-invasive live sperm sorting device enhances embryo euploidy rates, serving as a reliable sperm preparation method, ensuring selection consistency despite sample variations. Limitations, reasons for caution This study’s limitations include its retrospective nature and single-center trial design. To more effectively assess CA0 efficiency, a randomized controlled trial targeting diverse patient eligibility criteria is warranted. Wider implications of the findings Attributed to the improved embryo euploidy with CA0, we anticipate enhanced ART outcomes, such as increased embryo transfer rate and prevention of ART failures related to embryo aneuploidy. Additionally, CA0 offers practical benefits by streamlining and standardizing the sperm separation process with only three steps involved. Trial registration number not applicable

Investigating impulse purchases in live streaming e-commerce: A perspective of match-ups

Enabled by live streaming technologies, live streaming e-commerce (LSE) is becoming an increasingly promising marketing channel. Due to high entertainment and immersion, LSE greatly telescopes consumer decision journeys from awareness to purchase, thereby more readily stimulating consumer impulse purchase desire. This study reveals the influence of product-based fit on impulse purchases through affective and cognitive systems from the match-up perspective. The results indicate that both streamer-product fit and self-product fit enhance affective intensity and reduce perceived product risk. Unexpectedly, live content-product fit increases perceived product risk but has no significant impact on affective intensity. In addition, both streamer-product fit and live content-product fit enhance consumer perception of self-product fit, which, in turn, influences perceived product risks and affective intensity. However, emotion but not cognition breeds impulse purchase intention. Our findings can offer guidance for online retailers on how to utilize live streaming technology to increase sales.

EXPRESS: Community Gifting and Recipients Engagement with Peers and Influencers: Evidence from Natural Experiments on Twitch

Community gifting, the phenomenon of donating digital goods to peers without selecting specific recipients, is one of live streaming's key social technologies for engaging online communities. In this study, we investigate the causal relationship between receiving a community gift and the recipient's subsequent social and monetary engagement behaviors by exploiting the randomization of recipient assignment on the popular live streaming platform, Twitch. We find that, relative to nonrecipients within a five-minute window of a community gifting event, community gift recipients exhibit a 69% chance of directing an additional message toward their peers, a 35% chance of directing an additional message toward the streamer and a 5% chance of gifting an incremental subscription to the community. However, recipients are no more likely to tip the streamer. We apply computational linguistics methods to illustrate that recipients' increased social engagement is accompanied by elevated sentiment and an increased likelihood of joining existing conversations. Finally, we conduct a series of moderator analyses, and find that recipients' gifting behavior is less frequent when there are more gifting events prior to the focal community gift, i.e., allowing the recipient to hide. Moreover, the social engagement effect of receiving a community gift is greater when prior chatter is more voluminous and discontinuous, i.e., when it is easier for the recipient to jump into the chat. We conclude that the spillovers to social engagement are more important than those to financial reciprocity given the positive feedback loop implied by our moderator analysis. Our results reveal how and when community gifting impacts audience engagement.

Meditating in Live Stream: An Autoethnographic and Interview Study to Investigate Motivations, Interactions and Challenges

Mindfulness practice has many mental and physical well-being benefits. With the increased popularity of live stream technologies and the impact of COVID-19, many people have turned to live stream tools to participate in online meditation sessions. To better understand the practices, challenges, and opportunities in live-stream meditation, we conducted a three-month autoethnographic study, during which two researchers participated in live-stream meditation sessions as the audience. Then we conducted a follow-up semi-structured interview study with 10 experienced live meditation teachers who use different live-stream tools. We found that live meditation, although having a weaker social presence than in-person meditation, facilitates attendees in establishing a practice routine and connecting with other meditators. Teachers use live streams to deliver the meditation practice to the world which also enhances their practice and brand building. We identified the challenges of using live-stream tools for meditation from the perspectives of both audiences and teachers, and provided design recommendations to better utilize live meditation as a resource for mental wellbeing.

Make the invisible visible-innovation in the single fluorescent protein-based indicators

Biological phenomena are generated by the cooperative and hierarchical relationships between a variety of biomolecules, such as proteins, metabolites, signaling molecules, and ions. In many cases, however, these biomolecules do not have color, and it is difficult to observe them as they are. Therefore, it is necessary to "visualize" each molecule with color or fluorescence, and to analyze the functional relationships between them. The live cell imaging technology using single fluorescent protein (FP)-based indicators has contributed to the visualization of biomolecules. Single FP-based indicators, which change their fluorescence intensity upon binding to the target molecule, have been revolutionized into multicolor indicators by a series of innovative screening methods. On the other hand, we have established an original screening method using semi-rational molecular design and molecular evolution, and have developed many single FP-based indicators for various molecules such as cAMP and glucose. In this article, we focus on single FP-based indicators and introduce their development strategy and the history of screening method.

Application of Raman spectroscopy to the evaluation of F-actin changes in sea urchin eggs at fertilization.

The actin filaments on the surface of echinoderm oocytes and eggs readily undergo massive reorganization during meiotic maturation and fertilization. In sea urchin eggs, the actin cytoskeletal response to the fertilizing sperm is fast enough to accompany Ca2+ signals and to guide sperm's entry into the egg. Although recent work using live cell imaging technology confirmed changes in the actin polymerization status in fertilized eggs, as was previously shown using light and electron microscopy, it failed to provide experimental evidence of F-actin depolymerization a few seconds after insemination, which is concurrent with the sperm-induced Ca2+ release. In the present study, we applied Raman microspectroscopy to tackle this issue by examining the spectral profiles of the egg's subplasmalemmal regions before and after treating the eggs with actin drugs or fertilizing sperm. At both early (15 s) and late (15 min) time points after fertilization, specific peak shifts in the Raman spectra revealed change in the actin structure, and Raman imaging detected the cytoskeletal changes corresponding to the F-actin reorganization visualized with LifeAct-GFP in confocal microscopy. Our observation suggests that the application of Raman spectroscopy, which does not require microinjection of fluorescent probes and exogenous gene expression, may serve as an alternative or even advantageous method in disclosing rapid subtle changes in the subplasmalemmal actin cytoskeleton that are difficult to resolve.

Energy and Performance-Efficient Dynamic Consolidate VMs Using Deep-Q Neural Network

With cloud computing facing higher levels of big data than ever, the processor scale is rapidly expanding. Large clusters place a heavy burden on cloud service providers and the environment. High energy consumption decreases the economic benefits of cloud service providers, while enormous power demands pressure on the environment. The dynamic consolidation of virtual machines (VMs), which uses live migration technology to optimize resource usage and reduce energy consumption, is sufficient for saving energy while ensuring high performance with the desired level of quality of service (QoS) between cloud providers and users. In this paper, we propose a novel machine-learning algorithm called deep-Q neural network VM consolidation (DQNVMC) that combines the Q-leaning approach with deep learning neural network to find an approximately optimal solution. Furthermore, based on the real workload trace in the cloud environment, the experiments show that DQNVMC effectively reduces energy consumption while meeting the high performance of QoS requirements.

Intravital microscopy of satellite cell dynamics and their interaction with myeloid cells during skeletal muscle regeneration.

Skeletal muscle regeneration requires the highly coordinated cooperation of muscle satellite cells (MuSCs) with other cellular components. Upon injury, myeloid cells populate the wound site, concomitant with MuSC activation. However, detailed analysis of MuSC-myeloid cell interaction is hindered by the lack of suitable live animal imaging technology. Here, we developed a dual-laser multimodal nonlinear optical microscope platform to study the dynamics of MuSCs and their interaction with nonmyogenic cells during muscle regeneration. Using three-dimensional time-lapse imaging on live reporter mice and taking advantages of the autofluorescence of reduced nicotinamide adenine dinucleotide (NADH), we studied the spatiotemporal interaction between nonmyogenic cells and muscle stem/progenitor cells during MuSC activation and proliferation. We discovered that their cell-cell contact was transient in nature. Moreover, MuSCs could activate with notably reduced infiltration of neutrophils and macrophages, and their proliferation, although dependent on macrophages, did not require constant contact with them. These findings provide a fresh perspective on myeloid cells' role during muscle regeneration.

A Novel Approach for Energy-Efficient Container Migration by Using Gradient Descent Namib Beetle Optimization

Cloud services are increasingly available through containers due to their scalability, portability, and reliable deployment, particularly in microservices and smart vehicles. The scheduler component of cloud containers plays a crucial role in optimizing energy efficiency and minimizing costs due to the diversity of workloads and cloud resources. The growing demand for cloud services poses a challenge in terms of energy consumption. Optimizing energy consumption in servers is possible by utilizing live migration technology. This study aims to propose a hybrid model that facilitates the migration of containers from one server to another using Gradient Descent Namib Beetle Optimization (GNBO) algorithms, thereby reducing the energy consumption of cloud servers. The work is carried out through cloud simulation using Physical Machines (PM), Virtual Machines (VM), and Containers. Tasks are allocated to VMs in a round-robin manner. The Actor-Critic Neural Network (ACNN) is employed to predict the load of PMs, and overloading and underloading conditions are determined based on the load. The proposed GNBO hybrid optimization calculates the optimal solution considering predicted load, migration costs, resource utilization, energy consumption, and network bandwidth. This approach achieves a load of 0.177 MIPS, migration costs of 10.146 J, and optimizes energy consumption to 0.068 W.

Design of Virtual Anchor Based on 3Dmax

With the rapid development of virtual reality and live streaming technologies, virtual anchors have become increasingly popular in recent years. In this paper, we propose a design method of virtual anchors based on 3DMAX. Through the use of modeling, rigging, and animation techniques, virtual anchors with realistic appearances and human-like movements can be created.

In addition, we provide a case study on the design and implementation of a virtual anchor for a popular live streaming platform. Our results show that the use of 3DMAX in virtual anchor design can greatly enhance user engagement and improve the overall user experience.Virtual anchor design technology based on 3DMAX is a highly complex design work, which requires designers to have a variety of skills and creative capabilities, and needs to fully consider the needs of the audience and the development trend of the industry. Designers should also have certain cultural accumulation and creative ability, and be able to design an attractive and valuable virtual anchor image from the perspective of the audience.This paper analyzes the production and design of the current virtual anchors, in order to provide some reference significance for the production, operation and commercial realization of the virtual anchors in the future.

In-situ live jacking technology of corner transmission tower

Aiming at the current situation that the foundation of the corner transmission tower is corroded, sunken, or the height of the tower line is insufficient, innovative low-cost technology is proposed to upgrade the foundation in-situ based on no power outages, and the analysis of the whole process of the in-situ live jacking construction of the transmission tower is studied in this paper. Firstly, through elastic mechanical equilibrium relationship, two form-finding methods of numerical analysis are derived and the results of several form-finding methods are analyzed and compared by a project example, among which the result error of the finite element method and the catenary method is negligible, while the error of the parabolic method is about 2% compared with the first two methods, but it can meet the engineering requirements. Secondly, the relevant laws of internal force and deformation of the lifting process are summarized, and a comparative analysis of theoretical and measured results verified the reliability and safety of the technology. Through the calculation program of the self-compiled parabolic method, the laws of tower line changes during the lifting process of the transmission tower are summarized, providing technical support for engineering practice and reference for related research.
