Abstract 3935: Involvement of nanoscale physical communication in obesity-associated breast cancer severity

Abstract Obesity is a risk factor for several cancers, including breast cancer, and contributes up to 20% of cancer-related deaths. Growing evidence from both clinical and preclinical studies indicates that increased obesity is associated with increases in cancer incidence, progression, metastasis, and therapeutic resistance. According to the Centers for Disease Control and Prevention (CDC), more than 70% and 40% of American adults can be classified as overweight and obese, respectively. However, treatment strategies for dealing with cancer in obese patients have not advanced apart from lifestyle interventions. However, several signaling mechanisms have been proposed related to the inflammatory and metabolic impact of obese adipocytes in promoting cancer progression. However, a lack of mechanistic understanding led to no specific treatment strategies have been proposed which can specifically downregulate the key regulator by which obese adipocytes promote cancer progression. Thus, translational research initiatives are immediately needed to provide mechanistic justifications for these striking statistics in order to better serve this growing segment of the population. Here, we have shown the role of nanoscale physical communication between breast cancer cells and adipose tissue in promoting cancer progression. Using high-resolution optical and electron microscopy, we have found that breast cancer cells form nanoscale tubular communications with obese adipocytes. Moreover, the cancer cells hijack mitochondria from obese adipocytes. However, coculturing cancer cells and obese adipocytes in the Boyden chamber, allowing exosomal and paracrine communication but blocking direct physical communication, revealed negligible mitochondria transfer. This observation indicates an active transfer of mitochondria via nanotube. A significantly higher rate of mitochondria transfer from obese adipocytes to cancer cells has been observed than non-differentiated pre-adipocytes. The transfer of mitochondria results in an increase in the metabolism of the cancer cells. The mechanistic investigation of the nanotube formation revealed actin's presence as the major component in the nanotube. The exocyst-GTPase protein complex has a prime contribution in actin remodeling and nanotube formation. Inhibition of exocyst-GTPase using a pharmacological inhibitor results in a significant reduction in nanotube-mediated mitochondria transfer. Conclusion: Our goal is to (i) investigate the direct physical connection between adipocytes and cancer cells and the effect on cancer progression and (ii) eliminate mortality related to obesity-associated breast cancer severity by introducing a new therapeutic strategy. Here, we have shown how cancer cells communicate with obese adipocytes and receive additional metabolic power for proliferation. The in vivo investigation of the same is under progress.

Erotisme Sebagai Bentuk Dominasi Maskulin dalam Novel Adam Hawa Karya Muhidin M Dahlan

<p><em>Sexuality is a form of physical communication between men and women. Through sexual acts, both can show the dominant position between masculine and/or feminine. This research aims to outline issues related to the roles of men and women in terms of sexuality and identify which of the two is more dominant. The research method used is qualitative research with literature study. Primary data is obtained from the object of research, namely the novel Adam Hawa and secondary data is obtained by researchers from various sources considered relevant to this research. This research uses feminism theory with a masculine domination perspective. This study found that some of the erotic acts found allow women to be more dominant than men. But in fact, the dominance is not absolute because in reality men are still superior or dominant than women. Maia managed to conquer Idris and dominate their sexual relationship. Even with Adam, Maia successfully achieved revenge for her heartache. However, Maia's success is inseparable from the role of men, that the presence of Marfu'ah (Maia's child) is the fruit of her sexual actions with Idris (male</em><em>)</em><em>.</em></p>

Mixed Reality Virtual Device (MRVD) for seamless MR-IoT-Digital Twin convergence

Mixed Reality (MR) extends Augmented Reality (AR) by emphasizing real-time interactions and providing a more immersive experience with the seamless integration of contextual elements, such as spaces, situations, objects, and user behaviors. MR creates new opportunities across fields, such as the Internet of Things (IoT) and Digital Twins (DT), and advancements in Artificial Intelligence (AI). However, integrating these technologies poses challenges for data synchronization, particularly for MR devices with limited computing resources. This study proposes a novel architectural concept, called the MR virtual Device (MRVD), to address the problem. MRVD serves as a virtual counterpart to the MR physical device (MRPD), optimizing computation and communication using container technologies to enhance availability, portability, and scalability. By handling resource-intensive tasks, MRVD boosts performance and consistency, thereby improving the effectiveness and efficiency of the MR-IoT-DT convergence. Our experiments demonstrate MRVD’s concrete benefits in overcoming these challenges, offering a promising approach for future convergence applications.

A new synchronization result for fractional-order discrete-time chaotic systems via bandlimited channels

Recently, digital chaotic communication with limited bandwidth has seized the attention of several researchers. This interest stems from the fact that all physical communication channels are limited in bandwidth for data transmission. In furtherance of this, researchers and investigators in this area have put forward various new communication strategies based on synchronizing and controlling coupled chaotic systems evolving in discrete time. In this article, we present a new robust communication scheme based on the synchronization of two fractional-order discrete-time chaotic systems connected by bandlimited channels. The major contribution is to give a sufficient condition in term of the existing and updated parameters of the incorporated fractional-order system on one hand and the inserted filter coefficients, on the other hand. Once applied for data communications, the currently drawn up synchronization scheme pledges to enhance the transmission robustness. Indeed, the new considered parameters act like novel secret keys which widen the cipher key space. Primary and pertinent simulation curves and results performed on Matlab software portray and illustrate the effectiveness of our approach.

Embedded model control of networked control systems: An experimental robotic application

In Networked Control System (NCS), the absence of physical communication links in the loop leads to relevant issues, such as measurement delays and asynchronous execution of the control commands. In general, these issues may significantly compromise the performance of the NCS, possibly causing unstable behaviours. This paper presents an original approach to the design of a complete digital control unit for a system characterized by a varying sampling time and asynchronous command execution. The approach is based on the Embedded Model Control (EMC) methodology, whose key feature is the estimation of the disturbances, errors and nonlinearities affecting the plant to control and their online cancellation. In this way, measurement delays and execution asynchronicity are treated as errors and rejected up to a given frequency by the EMC unit. The effectiveness of the proposed approach is demonstrated in a real-world case-study, where the NCS consists of a differential-drive mobile robot (the plant) and a control unit, and the two subsystems communicate through the web without physical connection links. After a preliminary verification using a high-fidelity numerical simulator, the designed controller is validated in several experimental tests, carried out on a real-time embedded system incorporated in the robotic platform.

Optimising performances of LoRa based IoT enabled wireless sensor network for smart agriculture

The significance of maintaining food security is particularly emphasized in regions such as Malaysia, where there is a substantial reliance on imports of fruits and vegetables. The local farming industry requires advancements in technology to address the complexities of food production. This motivates the exploration of implementing Internet of Things (IoT) solutions to reduce reliance on manpower and enhance farming efficiency. However, the current integrated IoT solutions for smart farms can be expensive and complicated, rendering them redundant for small-area farms that do not require advanced technologies or machine learning. This study aims to optimize IoT LoRa parameter settings, focusing on providing affordable solutions tailored for fruit and vegetable farms. The main goal is to address the common issue faced by farmers—investing in expensive IoT-enabled wireless sensors without realizing a return on investment. To overcome this challenge, a simple and cost-effective IoT solution is proposed, utilising sensors and readily available applications to achieve efficient farming practises. The main objective is to develop an integrated IoT solution tailored for fruit and vegetable farms, facilitating improved productivity and growth. The solution incorporates sensors to monitor and control various aspects of crop cultivation, collecting essential data. The research development here also aims to inspire low-cost IoT solutions suitable for small-scale food plantation farms by using the long-range physical communication technique (LoRa) protocol. Leveraging IoT technologies in a simplified manner allows local farming industries to boost productivity, lower operational costs, and effectively address food security concerns.In addition to the IoT technology development for smart farms, the research here also investigates the various factors affecting the performance of LoRa-enabled IoT solutions for smart farms, including LoRa frequency, distance, environment, and the performance of the IoT system under different weather conditions, showed a significant effect on system performance (p ≤ 0.05). This comprehensive approach aims to contribute valuable insights for the development and implementation of cost-effective IoT solutions tailored for small-scale agricultural practices. In conclusion, this project demonstrates the efficency of LoRa-based IoT in agriculture and highlights areas for improvement. Future directions involve improving scalability, streamlining the user interface, and adding sophisticated features to support the development of productive, networked, and environmentally friendly farming methods.

Enhancing security for physical layer communication in RIS-aided MIMO-NOMA systems in the presence of an eavesdropper

This paper investigates the potential of leveraging a reconfigurable intelligent surface (RIS) in the multiple-input multiple-output non-orthogonal multiple access (MIMO-NOMA) wireless communication systems. In fact, NOMA improves spectral efficiency (SE) through power domain utilization, and RIS enhances the system performance by manipulating the propagation environment. In this paper, we investigate the physical layer security (PLS) of a RIS-aided MIMO-NOMA system serving two users in the presence of an eavesdropper (EV), where the channel state information (CSI) of the EV is unknown for the BS. To address the security challenge, we utilize secrecy outage probability (SOP) and minimize it by optimizing the RIS’s phase shift matrix, the beamforming vector, and the power allocation coefficients. Due to the non-convexity of the main optimization problem, we decompose the initial problem into three subproblems, and then, we propose an iterative approach to determine the unknown parameters alternately. The first subproblem involves obtaining the optimal beamforming vector and phase shift matrix using the semidefinite relaxation (SDR) method, which introduces high complexity. As an alternative, another algorithm is proposed based on the duality of the optimization problem, offering lower complexity and better accuracy for high-dimensional optimization problems. In this algorithm, the successive convex approximation (SCA) technique is employed to achieve the optimum phase shift matrix, and the stochastic gradient (SG) approach is used to determine the beamforming vector. Furthermore, the paper establishes the optimal values of power allocation coefficients by minimizing the difference between the SOPs of the two users. Finally, the simulation results demonstrate that the proposed power allocation coefficients scheme significantly enhances system performance compared to the existing fixed power allocation coefficients scheme.

Training of Deep Joint Transmitter-Receiver Optimized Communication System without Auxiliary Tools

Deep Joint transmitter-receiver optimized communication system (Deep JTROCS) is a new physical layer communication system. It integrates the functions of various signal processing blocks into deep neural networks in the transmitter and receiver. Therefore, Deep JTROCS can approach the optimal state at the system level by the joint training of these neural networks. However, due to the non-differentiable feature of the channel, the back-propagation of Deep JTROCS training gradients is hindered which hinders the training of the neural networks in the transmitter. Although researchers have proposed methods to train transmitters using auxiliary tools such as channel models or feedback links, these tools are not available in many real-world communication scenarios, limiting the application of Deep JTROCS. In this paper, we propose a new method to use undertrained Deep JTROCS to transmit the training signals and use these signals to reconstruct the training gradient of the neural networks in the transmitter, thus avoiding the use of an additional reliable link. The experimental results show that the proposed method outperforms the additional link-based approach in different tasks and channels. In addition, experiments conducted on real wireless channels validate the practical feasibility of the method.

Physical punishment and effective verbal communication in children aged 9–36 months, according to sex: secondary analysis of a national survey

BackgroundA substantial number of children in the world are regularly subjected to physical punishment by their parents as a method of upbringing. Evidence suggests that it has negative effects on the development of brain function. However, evidence regarding its association with verbal communication is limited and heterogeneous. It is also unknown whether the effects are the same in both boys and girls; especially in the contexts of developing countries, where the highest rates of physical punishment are found.ObjectiveThis investigation aimed at analyzing the association between physical punishment administered by both fathers and mothers and effective verbal communication among children aged 9–36 months according to sex.MethodsA secondary analytical cross-sectional study was conducted based on the 2018–2019 Peruvian Demographic and Family Health Survey. Physical punishment, based on the mother’s report of the use of hitting and/or slapping, was considered as a method to correct children by the father and/or mother. Effective verbal communication (EVC) was measured using the Battle scale which consists of age-appropriate questions included in the early childhood development module. A generalized linear model of the family and Log Poisson link option was used to identify the association between them, using the crude, general adjusted, and sex-stratified models.ResultsOf all the children, 16.31% received physical punishment from their father and/or mother, wherein 16.65% were boys and 15.97% were girls. Moreover, 36.48% exhibited EVC, wherein 32.55% were boys and 40.50% were girls. Adjusting for socioeconomic level, witnessing violence, mother’s marital status, age, occupation, education level, language, number of children, and moderate-to-severe depressive symptoms, it was found that boys who received physical punishment from their father and/or mother have a 31% lower probability of EVC (adjusted prevalence ratio (aPR) 0.69, 95% confidence interval (CI) 0.58–0.83, p < 0.001), whereas no association was found in girls who received physical punishment from their father and/or mother and EVC (aPR 0.93, 95% CI 0.81–1.06, p = 0.278).ConclusionsAn association was found between physical punishment administered by father and/or mother and reduced EVC among boys, whereas no such association was found among girls. It is possible that even though a significant impact has not been observed in girls during this early stage, they may experience consequences in later stages of life, further research is needed.

Deciphering Digital Body Language and the Gen-Z in New Normal

The post-pandemic era or the era of the new normal has kept us all on tenterhooks since the unanticipated inception of the pandemic. The world reluctantly and gradually slithered on the spine of technology and took the reign to bridge the gap that slid between the crevices of the online and offline world, the normal and the new normal, non-digital and digital communication. Digital body language - an integral part of digital communication, is an idea that has gained momentum recently in the new normal, where digital-only communication is seen progressively as something inexorable. We find ourselves surrounded by communication that most of the time occurs exclusively digitally. Digital body language, like physical body language, plays the same integral and vital role in communication, where the former is more difficult to decipher. While communicating on digital platforms, occupying the digital space via email, messenger, chat, or video call, there are more chances of misunderstanding and more nuances to deal with, than in physical communication.&#x0D; Gen z, iGen, or centennials born between 1995 and 2012, are the generation born with the internet and mobile phones in their pockets- which generously offered them earlier exposure to communication skills and digital communication. The present chapter seeks to explore in its first part, analyzing how and in what ways we need to acquire an understanding of digital body language to dissolve the barriers and filters present, to communicate effectively. In the second part, there is a discussion on how equipped is the Gen z- the communication generation- to combat the challenges of the digital space imposed by digital body language and what we need to learn from them.&#x0D;  

Comparisons between group- and individual-based interventions to support recovery from stroke and ischaemic heart disease in the community: a scoping review

Purpose To map and summarise available literature on the effectiveness or other benefits of group- and individual-based interventions provided for adults living with stroke or ischaemic heart disease (IHD) in the community. Material and Methods The review was conducted based on JBI methodology and reported using Preferred Reporting Items for Systematic reviews and Meta-Analyses extension for Scoping Reviews. Articles were retrieved from: Medline, PsychInfo, Embase, Scopus, and CINAHL from 2002–2022. Extracted data from eligible studies included type of health outcomes (e.g., impairments), retention and adherence, social connectedness, and the costs associated with group- and individual-based interventions. Results After screening, five articles (representing 4 unique studies) comparing a group- and individual-based intervention were included (total sample size n = 87). Three types of interventions were assessed: exercise (3/5), communication (1/5), and occupational therapy (1/5). Effectiveness of group- and individual-based interventions at improving health outcomes (i.e. physical ability, communication, motivation, and quality of life) is unclear. Currently there is insufficient evidence to guide clinical practice. Conclusions There is limited evidence comparing interventions delivered in a group and individual modality for adults living with stroke or IHD. Adequately powered studies are needed to determine if mode of delivery is equivalent or more cost effective.

Assessment of Cyber-Physical Inverter-Based Microgrid Control Performance under Communication Delay and Cyber-Attacks

The integration of communication infrastructures into traditional power systems, transforming them into cyber-physical power systems (CPPS), accentuates the significance of communication in influencing system performance and sustainability. This paper presents a versatile, innovative cyber-physical co-simulation framework that integrates the physical power system and communication networks, uniting OPAL-RT, a network simulator (ns3), and Docker containers into a sophisticated platform, facilitating intensive studies into CPPS dynamics. The proposed experimental study provides an innovative way to assess the frequency control response of a cyber-physical inverter-based microgrid (MG), addressing the MG sustainability challenges. We consider diverse real-world scenarios, focusing on communication delays and distributed denial of service (DDoS) attacks within the communication channels. We propose a precise ns3-based communication model that bridges the MG’s primary and secondary control layers, an aspect often overlooked in previous studies; this is a noteworthy contribution to elucidating the adverse impacts of communication latency on MG frequency performance. The experimental results demonstrate the effectiveness of the centralized secondary controller in eliminating the frequency deviations. Furthermore, the findings offer insights into stable and unstable regions, revealing how the communication delay value affects the frequency stability under different operating conditions. In addition, the developed real-time DDoS attacks model within the proposed communication surface unveils crucial insights into the MG’s resilience to cyber threats. This work’s revelations offer a foundational awareness of MG vulnerabilities, paving the way for designing robust and resilient communication networks and control strategies within the cyber-physical inverter-based microgrids.

Enabling particle transport on CAD-based geometries for radiation simulations with penRed

Geometry construction is a fundamental aspect of any radiation transport simulation, regardless of the Monte Carlo code being used. Typically, this process is tedious, time-consuming, and error-prone. The conventional approach involves defining geometries using mathematical objects or surfaces. However, this method comes with several limitations, especially when dealing with complex models, particularly those with organic shapes. Furthermore, since each code employs its own format and methodology for defining geometries, sharing and reproducing simulations among researchers becomes a challenging task. Consequently, many codes have implemented support for simulating over geometries constructed via Computer-Aided Design (CAD) tools. Unfortunately, this feature is lacking in penRed and other PENELOPE physics-based codes. Therefore, the objective of this work is to implement such support within the penRed framework.

In the same way as many other Monte Carlo codes, penRed employs simple geometric quadric surfaces like planes, spheres and cylinders to define geometries. However, since these geometric models offer a certain level of flexibility, these representations have limitations when it comes to simulating highly intricate and irregular shapes. Anatomic structures, for example, require detailed representations of organs, tissues and bones, which are difficult to achieve using basic geometric objects. Similarly, complex devices or intricate mechanical systems may have designs that cannot be accurately represented within the constraints of such geometric models. Moreover, when the complexity of the model increases, geometry construction process becomes more difficult, tedious, time-consuming and error-prone [2]. Also, as each Monte Carlo geometry library uses its own format and construction method, reproducing the same geometry among different codes is a challenging task.Solution method: To face the problems stated above, the objective of this work is to implement the capability to simulate using irregular and adaptable meshed geometries in the penRed framework. This kind of meshes can be constructed using Computer-Aided Design (CAD) tools, the use of which is very widespread and streamline the design process. This feature has been implemented in a new geometry module named “MESH_BODY” specific for this kind of geometries. This one is freely available and usable within the official penRed package1. It can be used since penRed version 1.9.3b and above.

OpenFuelCell2: A new computational tool for fuel cells, electrolyzers, and other electrochemical devices and processes

Fuel cells/electrolyzers are efficient and clean electrochemical devices that convert chemical energy directly into electricity and vice versa. They have attracted sustainable attention over the past decade from multiple experimental and numerical studies. However, detailed experimental investigations are typically expensive and challenging for providing a number of operating conditions and designs. Computational analysis offers an alternative approach for these studies. With the steadily increasing high-performance computing resources available, the limitations of numerical simulations have substantially decreased. This contribution details the design choice and code structure of modern electrochemical devices, which have been implemented as a versatile C++ library named openFuelCell2 within the open-source platform OpenFOAM, allowing for large-scale parallel calculations to be performed. The solver considers the major transport phenomena in a typical electrochemical device, including fluid flow, heat and mass transfer, species and charge transfer, and electrochemical reaction. This enables numerical simulations on popular electrochemical devices, such as fuel cells and electrolyzers, to be conducted. The paper also describes the domain decomposition, and parallel performance issues, as well as future applications.

This toolbox provides researchers with a powerful tool for studying electrochemical devices in a comprehensive and efficient manner.Solution method: This software utilizes the finite volume method (FVM) to discretize and solve all conserved variables governed by partial differential equations. It employs a variant of the SIMPLE and PISO algorithms, known as PIMPLE, to solve the pressure-velocity coupling. All of the transport equations are solved sequentially, except for the enthalpy equation which is solved in an implicitly coupled manner within the global domain.Additional comments including restrictions and unusual features:•The two-phase flow consists of continuous and dispersed phases, without resolving the phase interfaces.•The two-phase flow is solved with an Eulerian-Eulerian approach.•A local-time-stepping method was typically used in the two-phase solution.•The electrochemical reactions take place in volumetric regions.•Species diffusion is described by Fick's law.

When Faces Disappear – A Call for Combining Autoethnography and Complexity Thinking in Future Research on the Intersection of Physical Spaces, Technology and Healthcare Communication Education during COVID

Autoethnography and complexity thinking should be carefully combined when studying the intersection of physical spaces, technology and healthcare communication education as it took place during COVID. This is the call that stems from a sequential examination of existing literature. Initially, this process identified that existing research tendencies emphasize the need to understand the role physical spaces have in educational processes and highlight the demand to inquire about the opinions of educators regarding these spaces. Subsequently, analysing the manner in which these tendencies are reflected in the literature connected to teaching during COVID, showed that published research demonstrates the evocative potential of educator autoethnographies. Concomitantly, three themes stood out in the examined works: 1. physical spaces form the taken-for-granted skeleton of human existence which can be further explored, 2. matters of communication dominate the literature and set-out many yet to be probed questions and 3. physical spaces, technology and education are undeniably and complexly connected. Altogether, these findings help make the argument that future studies should investigate different instances of the following overarching question: what can be learned about teaching healthcare communication during COVID by using a complexity sensitized autoethnographic investigation focused on the physical spaces-technology-education intersection?

Measuring the impact of healthcare service quality of hospitals on customer satisfaction

Various studies have been conducted to measure the level of service provided by an institution or service, including hospitals, in order to determine the level of customer satisfaction. The purpose of this research is to assess the role of the quality of services offered by a hospital in predicting customer satisfaction. This study was conducted at Bunda Purwokerto Hospital. The participants consisted of 380 samples. Hypothesis testing using the Smart PLS method yielded an R-square value of 0.413 for the customer satisfaction variable. The results of H1 revealed a favourable influence on the satisfaction of outpatient patients at Bunda Purwokerto Hospital. The original sample produced a coefficient of 0.130, a t statistic of 2.163 (&gt; 1.96), and a p-value of 0.031 (&lt; 0.05). The relationship between trust and job performance was deemed positive and significant, as evidenced by the t-statistic exceeding 1.96. This study confirms that an improvement in the quality of healthcare services shapes patient satisfaction and loyalty. Aspects encompassing healthcare service quality, such as the physical environment, customer-oriented atmosphere, responsiveness, effective communication, privacy maintenance, and safety, demonstrate a positive correlation with patient loyalty towards the hospital’s image.
