Preferred Orientation and Phase Distribution of Quasi-2D Perovskite for Bifunctional Light-Emitting Photodetectors.

In traditional optical wireless communication (OWC) systems, the simultaneous use of multiple sets of light-emitting diodes (LEDs) and photodetectors (PDs) increases the system complexity and instability. Here we report bifunctional light-emitting photodetectors (LEPDs) fabricated with quasi-2D perovskite (F-PEA)2Cs4Pb5I11Br5 as light-emitting/detecting layers for efficient, miniaturized, and intelligent bidirectional OWC. By simply changing the solvent composition of the precursor solution and using antisolvent engineering, we manipulated the crystal orientation and phase distribution of (F-PEA)2Cs4Pb5I11Br5, realizing high irradiance (4.36 μW cm-2) and a -3 dB refresh rate (0.21 MHz) of electroluminescence in LED mode as well as low noise (below 1 pA Hz-1/2) and high responsivity (0.1 A W-1) in PD mode. The rapid and accurate OWC process was demonstrated through interaction of LEPDs. We also demonstrated the high-fidelity compression and digitization of high-resolution (256 × 256 pixels) color images using the four-step phase shift method to realize intelligent encrypted image OWC.

Exploring Teacher-Student Interaction in a Synchronous Online Modality: A Critical Discourse Analysis

The rise of online education, prompted by challenges posed by the COVID-19 pandemic, has revolutionized the education landscape and challenged the traditional norms and communications that have characterized communication in the education sector. This research, drawing on the interplay between Critical Discourse Analysis and Sinclair’s IRF model, peers into how language power is played out in cyberspaces of a virtual classroom. The study traces language’s hidden yet palpable influence in shaping power relations through an examination of various online engagements. Findings from the study show that teachers use rhetorical questions and affirmations to guide discussions and retain power based on Sinclair’s IRF model. On the other hand, Wodak’s CDA framework brings out the hidden power dimensions that lie unnoticed in language, which seems inclusive but seeks control. The outcome confirms how language influences power dynamics when teachers use linguistic strategies to shape narratives and dictate conversations. The study reveals strategies instructors utilize in General Education courses at Camarines Sur Polytechnic Colleges, Philippines. While appearing democratic, rhetorical questions and affirmations maintain the teacher’s authority as they help create an illusion of equality. The paper emphasizes the necessity of understanding language-power interplay in online education and advocates for including a course component devoted to language and power dynamics in teacher professional development programs. This awareness creates inclusive environments in online learning spaces where various voices are recognized, encouraging shared knowledge development. This research illuminates the intricate nature of language and power, laying the foundation for informed online learning teaching practices.

A Study of Content Consumption and Information Interaction Based on Emerging Media

With the convergence and interweaving of attention economy and communication focus, the hot media, as a means of transporting and understanding meanings without the need to mobilise multiple senses, is gradually breaking down the traditional communication boundaries and framework limitations. This paper strategically analyses the practices of content consumption and information interaction in emerging media from the perspective of "media ecological niche" theory. Taking Netease Cloud Music's "time-limited advertisement viewing" and "click-and-skip membership service" as the starting point and combining the concepts of cross-platform product operation cost and user group overlap, the paper points out that media products need to be constructed in the context of production. It is pointed out that media products need to shift the focus on human values, emotional realisation and consumer relations in the production construction, so as to realise the true symbiosis and mutual compatibility of discourse output and value derivation under the convergence ecology.

Critical Thinking in the Age of Expanded Telepathy and Brain-Computer Interface (BCI)

Unveiling a world of expanded telepathy, the study investigates the convergence of cosmological awareness and brain-computer interface (BCI) technologies. It delves into the evolution or potential disappearance of individual critical thinking in a posthuman era, exploring the emergence of a new form of criticality beyond human boundaries. By envisioning a future where telepathy becomes a reality, the paper examines the direct sharing of mental states, bypassing traditional communication methods and raising profound questions about the nature of consciousness and intentionality.

Wireless Communication-aware Path Planning and Multiple Robot Navigation Strategies for Assisted Inspections

Among the many challenges robots encounter in the mining industry, exploring confined environments receives significant attention. This work tackles problems associated with robot communication in hazardous and confined environments, where its cluttered and extensive nature frequently precludes traditional cable-based and wireless solutions. Our methods resort to off-the-shelf long-range radio frequencies to profile the signal propagation behaviour over the geometrical map to assist navigation algorithms that seek to preserve the connection. We consider mathematical models to predict signal power behaviour and serve as input to path planning. We also propose a semi-autonomous leader-follower scheme, with signal repeater units forming a mobile wireless network to enable inspection in hard-to-reach locations. Finally, we present a multi-robot connection-aware system, combining path planning based on radio signal power with multiple robot navigation. Results show the applicability of the proposed solutions, generating single and multi-robot paths for optimal signal reception based on power estimation, thus enabling operations in remote and isolated areas with no line-of-sight between the command base and the robotic inspection device. Experiments conducted in long corridors and in a representative mining environment using the EspeleoRobô and Pioneer platforms demonstrate significant improvements over the traditional communication methods for robotic operation regarding communication quality and inspection range limits.

Principle and design of vanadium-doped fiber laser under simulation

Due to the low efficiency of traditional communications and many problems, the development of optical fiber communications is currently necessary. Among them, fiber laser is the core of fiber communication, and the higher the output band of a fiber laser, the more information it carries, and the information that can be transmitted increases accordingly. Therefore, the primary goal is to develop a fiber laser with high-band output. At present, research on high-band output fiber lasers is being carried out at home and abroad. Domestic research focuses on the selection of fiber media; foreign research focuses on random fiber lasers. This article adopts the domestic research route, based on the premise that vanadium ions can emit laser wavelengths that include the L+ band when performing energy level transitions. At the same time, vanadium-doped gallium lanthanum sulfide glass has good functions of absorbing pump light and emitting lasing light. Therefore, this article mainly discusses the design of vanadium-doped fiber lasers using vanadium-doped gallium sulfide as the gain medium under simulation conditions to achieve high-band output of fiber lasers.

Protocol-based state estimation of two-time-scale complex networks with nonhomogeneous sojourn probabilities

This paper is dedicated to researching the problem of the state estimation for two-time-scale complex networks (TTSCNs) subject to sojourn probabilities (SPs) under channel fadings and false data injection attacks (FDIAs). The network’s switching topology is governed by a novel switching law that incorporates time-varying SPs, with the variation of SPs being regulated through a persistent dwell-time (PDT) switching signal. Meanwhile, for the sake of achieving energy savings and mitigating data congestion, the dynamic probabilistic event-triggered weighted try-once-discard (DPEWTOD) policy is innovatively developed by integrating with the major merits of the dynamic probabilistic event-triggered mechanism (DPETM) and WTOD protocol (WTODP) based on hybrid compensation. Different from the traditional communication rules, this DPEWTOD concept not only captures stochastic behavior of the dynamic triggering threshold (DTT), but also enables a compensatory measurement that closely approximates the actual value. Subsequently, we construct time delay-, DTT-, and PDT-dependent Lyapunov functionals to analyze the stability of error dynamic systems in the presence of fading and malicious FDIAs. By employing a separation technique, our proposed solving algorithm transforms non-convex analysis conditions into tractable ones. Eventually, the rationality and effectiveness of the proposed method are demonstrated by an resistance–capacitance (RC) circuit example.

Sign of slant receiver for skewed alpha-stable noise shift keying-based random communication system

Purpose In contrast to traditional communication systems, slower data rate has always remained a weak link for non-traditional random communication systems (RCSs), which use alpha-stable (a-stable) noise as a carrier. This paper aims to introduce a fast receiver for skewed a-stable noise shift keying (SkaSNSK)-based RCSs. Design/methodology/approach The introduced receiver is based on the sign of slant estimator (SoSE), which provides rapid estimation of the skewed a-stable random noise signals (RNSs) received from the additive white Gaussian noise channel. The SoSE-based receiver minimizes the number of samples required to extract the encoded information from the received RNSs. This is achieved by manipulating the antipodal properties of the slant/skewness parameter of the a-stable carrier. Hence, a high data rate with relatively low complexity is guaranteed. Findings In comparison with the previously introduced sinc, logarithmic and modified extreme value method-based receivers, the proposed SoSE-based receiver also achieves improved bit error rate (BER) along with the better covertness values so that the essence of security provided by SkaSNSK-based RCSs remains intact. Research limitations/implications Because of the selected range of the associated parameters of the a-stable noise as a carrier, the BER vs MSNR results are may lack applicability for the complete range of values. Therefore, further research is required to produce results in different ranges. Practical implications The study includes implications for the hardware development based on the proposed communication scheme. Originality/value It can be seen that the paper fulfils the desired need of a fast receiver design for RCS.

Traditional and Modern Sources of Information “Serving” the Image of the Public Employer – A Generational Perspective

Abstract The image of public organizations as employers, including security institutions such as the Polish Army, is an intangible, subjective and changeable aspect, which is shaped, among other things, using modern and traditional communication platforms. The preference of information sources is an important issue in the process of employer branding, as the selection and use of the right sources of information allows to effectively inform target groups, increase the level of knowledge about the attributes of the military as an employer, eliminate misinformation and respond more quickly to image crises. With the above in mind, the purpose of the conducted research was to identify the sources of information about the military used by representatives of three generations operating in the modern labor market, including the search for a relationship between the level of attractiveness of the Polish Army and the sources of information used by the public. The conducted research aimed to show how important it is to know the target groups, their preferences, and needs, in the context of the process of building the image of a public institution as an attractive employer.

Off-camera gaze decreases evaluation scores in a simulated online job interview

During the pandemic, digital communication became paramount. Due to the discrepancy between the placement of the camera and the screen in typical smartphones, tablets and laptops, mutual eye contact cannot be made in standard video communication. Although the positive effect of eye contact in traditional communication has been well-documented, its role in virtual contexts remains less explored. In this study, we conducted experiments to gauge the impact of gaze direction during a simulated online job interview. Twelve university students were recruited as interviewees. The interview consisted of two recording sessions where they delivered the same prepared speech: in the first session, they faced the camera, and in the second, they directed their gaze towards the screen. Based on the recorded videos, we created three stimuli: one where the interviewee’s gaze was directed at the camera (CAM), one where the interviewee’s gaze was skewed downward (SKW), and a voice-only stimulus without camera recordings (VO). Thirty-eight full-time workers participated in the study and evaluated the stimuli. The results revealed that the SKW condition garnered significantly less favorable evaluations than the CAM condition and the VO condition. Moreover, a secondary analysis indicated a potential gender bias in evaluations: the female evaluators evaluated the interviewees of SKW condition more harshly than the male evaluators did, and the difference in some evaluation criteria between the CAM and SKW conditions was larger for the female interviewees than for the male interviewees. Our findings emphasize the significance of gaze direction and potential gender biases in online interactions.

A new quantum group blind signature scheme based on GHZ states

With the development of quantum computers, traditional communication security based on classical computers can no longer guarantee unconditional security. At the same time, a series of encrypted communication solutions that rely on quantum mechanical properties have been spawned. This article focuses on the field of quantum signatures, based on the entangled Greenberger–Horne–Zeilinger state, combining group signatures (any member of the group can sign on behalf of the group) and blind signatures (the signer cannot know the accuracy of the signature content) proposed a new quantum group blind signature scheme that utilizes quantum key distribution to achieve unconditional security. By splitting the original message, the scheme strengthens the relevance of the signature participants and makes the signature to have stronger binding. Then, the security of the scheme against internal and external attacks is analyzed. In this scheme, a pleasing efficiency has been achieved, and the non-repudiation of signatures has been enhanced. At the same time, disputed signatures can be traced back to the signer.

Urban Tourism Appeal: The Effectiveness of Communication Channels and Multimedia Formats in Creating Tourists’ Expectations

Tourists’ expectations related to urban tourist destinations, which often derive from wider concept of destinations’ images, encompass a wide range of needs, desires and anticipations that tourists develop prior to visiting a particular destination. They are formed under the influence of different factors, one of which is traditional and digital communication channels. The objective of this research is to determine whether different communication channels and multimedia formats, used by tourists in the pre-travelling phase, could shape their expectations related to tangible and intangible characteristics of urban tourist destinations. The data gathering was conducted by applying Computer-Aided Web Interviewing (CAWI) on a representative sample of 312 adult citizens residing in Belgrade, the capital of the Republic of Serbia. The findings indicate that both traditional and digital communication channels, alongside personal recommendations used prior to the trip, significantly contribute to shaping respondents’ expectations concerning tangible characteristics of urban tourist destinations. Digital communication channels and personal recommendations appeared to be more important in shaping expectations related to the intangible characteristics of urban tourist destinations. Also, different formats of online media content exhibited positive associations with expectations concerning the tangible and intangible characteristics of urban tourist destinations. The obtained results provide recommendations for tourist organizations and local government entities, valuable for developing effective communication strategies for targeting potential tourists.

RSMA-aided V2X communications: A multi-layer perspective

Rate-splitting multiple access (RSMA), a novel technology in next-generation mobile communications, has garnered increasing attention for its powerful and flexible interference management when compared to traditional multiple access methods. However, considering classical vehicle-to-everything (V2X) communication networks with multiple cells, the flexibility of decoding increases with an increasing number of users having different requests, which results in higher outage performance and additional energy consumption. In order to address these problems, this paper proposes a novel multi-layer (ML) RSMA scheme, aiming to enhance the system performance and decrease the decoding flexibility simultaneously. For the first layer, users enjoying optimal quality of service (QoS) are selected to aid the other cluster members. For the second layer, the cluster members are grouped following the QoS and request similarity. In addition, with respect to our proposed ML-V2X RSMA system, this paper investigates the performance over Rayleigh fading channels, where we derive closed-form expressions of achievable sum rate and outage probability, respectively. Numerical results reveal that: (1) For low SNR scenarios, the ML-V2X RSMA system achieves higher achievable sum rates than classical NOMA-aided V2X systems. (2) The outage probability of ML-V2X RSMA system is superior to that of NOMA-aided V2X systems and traditional cooperative communication systems.
