Band-Stop Behavior Vertically Extended Ground Isolator Based on Transmission Line Theory for IBFD TRx Decoupling Applications

This article presents decoupling methodologies enabling dual-polarized coupling suppression for fifth-generation (5G) sub-6 GHz transmit/receive (TRx) antenna arrays with novel antenna illumination topologies. The isolator comprises the proposed vertically extended bent ground wall, which acts like a multistage band-stop filter modeled as a transmission line, i.e., it has a different behavior from the typical wall structure. To consider dual-polarized multi-path isolations in reliable 5G integration scenarios, an antenna having a height of <inline-formula> <tex-math notation="LaTeX">$0.13\lambda $ </tex-math></inline-formula> at 3.5 GHz with dual (±45° slant) polarization and port isolation of 25 dB is devised. It was demonstrated that the proposed isolator could significantly suppress the direct and ground coupling between TRx, using the resonance proven by transmission line theory. Moreover, the isolator composite combined with an electromagnetic band-gap (EBG) can further improve their dual-polarized decoupling by removing the surface wave coupling. Two sets of 3.5 GHz <inline-formula> <tex-math notation="LaTeX">$1 \times 4$ </tex-math></inline-formula> antenna arrays with 45°-slant polarization and the proposed isolator composite were designed, manufactured, and measured for simultaneous decoupling of eight paths among the TRx antenna elements. Finally, the measured results reveal that the overall isolation level of the dual-polarized array configuration is approximately 70 dB with a height of <inline-formula> <tex-math notation="LaTeX">$0.14\lambda $ </tex-math></inline-formula>, maintaining the matching and port isolation conditions.
Sustainability Evaluation: Measurement of Dimensions in Accredited Universities in a Developing Country

Due to the new paradigm of university education, universities must implement sustainability in their missionary functions and administrative areas to increase their reputation, obtain external financing and create a competitive advantage. For this reason, this research aims to propose a university sustainability evaluation model for accredited institutions, in the context of developing countries where the implementation of sustainability presents notorious lags. A measurement tool for student perception of university sustainability was built through a review, grouping of dimensions, expert testing, pilot testing, exploratory and confirmatory analysis. The survey was applied in nine accredited universities to 1.276 students of various semesters and professions. The review of the literature yielded various evaluative models on university sustainability. Thus, the theoretical results and the quantitative validation of the findings validated the constructs and as a result, the dimensions of the institutional framework, campus operations and missionary functions stood out with high statistical significance, evidencing the relevance of the measurement instrument. Therefore, these categories are considered central to the evaluation processes, just as greater emphasis should be placed on the dimensions referring to missionary functions. This research is innovative because it is one of the first evaluation models of university sustainability formulated from the perspective of the student in a developing country for institutions that must account for their progress in the implementation of sustainability, such as universities with high quality accreditation.
Anomalies in the ‘Dark Side’ of Tourism: Resistance to Popular Sites in Samarinda, Indonesia

The term ‘destination security’ is found in the customs and norms applied to prevent conflicts between tourism actors, local communities and the surrounding environment. The emergence of resistance to a destination because of its ‘dark side’, both those interested or actually visiting, cannot be separated from the fact that tourists are victims of violations of the law. The purpose of this study is to explore the effect of criminal acts on the numbers of tourists in Samarinda. Operationally, the core variables are divided into material effects, non-material effects and tourist volume. The data sample focuses on local, domestic and international tourists visiting popular sites in Samarinda during 2011–2021. The results of the investigation found that both material and non-material effects contributed to reducing the volume of tourists in the short term. In the long term, the presence of extortion, theft, sexual harassment and racism seems likely to reduce the volume of tourists.
Film-induced tourism

The majority of films today are not produced with the intent to lure people to visit certain destinations. However, in a sense a destination in a film can be seen as a form of product placement that consumers are willing to spend money on to experience. People can, from their TV sofa or cinema chair, gaze upon places, people, stories and other depictions of attributes that a film consists of. When an attribute stands out it can be powerful enough to create a pulling power for the viewers to travel to the film location and see or experience it in reality. This phenomenon has been referred to as film-induced tourism and is still a relatively unexplored area containing many research gaps. This book attempts to fill some of those gaps and find connections between them in order to better understand the occurring processes within film-induced tourism. Destination images, travel motivation, authenticity and travel behaviour in a film tourism context are discussed and analysed. This book should be of interest for professionals in tourism, destination marketing, advertising and branding as well as governmental organs interested in ways to promote cities and countries.
Compuestos naturales, modelos murinos y su aplicación en el estudio del lupus eritematoso sistémico

A principios del siglo XX, el médico y bacteriológo alemán Paul Ehrlich, introdujo el término “horror autotoxicus” para describir el proceso por el cual el sistema inmunológico de un individuo ataca y daña tejidos propios (Silverstein, 2001). Actualmente, este tipo de trastornos son conocidos como enfermedades autoinmunes como por ejemplo el Lupus Eritematoso Sistémico (LES).
Metric networks for enhanced perception of non-local semantic information

Introduction Metric learning, as a fundamental research direction in the field of computer vision, has played a crucial role in image matching. Traditional metric learning methods aim at constructing two-branch siamese neural networks to address the challenge of image matching, but they often overlook to cross-source and cross-view scenarios. Methods In this article, a multi-branch metric learning model is proposed to address these limitations. The main contributions of this work are as follows: Firstly, we design a multi-branch siamese network model that enhances measurement reliability through information compensation among data points. Secondly, we construct a non-local information perception and fusion model, which accurately distinguishes positive and negative samples by fusing information at different scales. Thirdly, we enhance the model by integrating semantic information and establish an information consistency mapping between multiple branches, thereby improving the robustness in cross-source and cross-view scenarios. Results Experimental tests which demonstrate the effectiveness of the proposed method are carried out under various conditions, including homologous, heterogeneous, multi-view, and crossview scenarios. Compared to the state-of-the-art comparison algorithms, our proposed algorithm achieves an improvement of ~1, 2, 1, and 1% in terms of similarity measurement Recall@10, respectively, under these four conditions. Discussion In addition, our work provides an idea for improving the crossscene application ability of UAV positioning and navigation algorithm.
Enhanced Thermoelectric Properties of Nb-Doped Ti(FeCoNi)Sb Pseudo-Ternary Half-Heusler Alloys Prepared Using the Microwave Method

Pseudo-ternary half-Heusler thermoelectric materials, which are formed by filling the B sites of traditional ternary half-Heusler thermoelectric materials of ABX with equal atomic proportions of various elements, have attracted more and more attention due to their lower intrinsic lattice thermal conductivity. High-purity and relatively dense Ti1−xNbx(FeCoNi)Sb (x = 0, 0.01, 0.03, 0.05, 0.07 and 0.1) alloys were prepared via microwave synthesis combined with rapid hot-pressing sintering, and their thermoelectric properties are investigated in this work. The Seebeck coefficient was markedly increased via Nb substitution at Ti sites, which resulted in the optimized power factor of 1.45 μWcm−1K−2 for n-type Ti0.93Nb0.07(FeCoNi)Sb at 750 K. In addition, the lattice thermal conductivity was largely decreased due to the increase in phonon scattering caused by point defects, mass fluctuation and strain fluctuation introduced by Nb-doping. At 750 K, the lattice thermal conductivity of Ti0.97Nb0.03(FeCoNi)Sb is 2.37 Wm−1K−1, which is 55% and 23% lower than that of TiCoSb and Ti(FeCoNi)Sb, respectively. Compared with TiCoSb, the ZT of the Ti1−xNbx(FeCoNi)Sb samples were significantly increased. The average ZT values of the Nb-doped pseudo-ternary half-Heusler samples were dozens of times that of the TiCoSb prepared using the same process.
Performance Improvement of Rare-Earth Free High-Speed Multilayer IPMSM Using Dual-Phase Magnetic Material

This paper proposes the performance improvement of the rare-earth free high-speed multilayer (ML) IPMSM by using the dual-phase magnetic material (DPMM). To ensure mechanical stability, ML IPMSM should have many bridges. However, in the bridges, a significant leakage flux generates, and, due to this, the performance of the motor is decreased. Since the DPMM has magnetic and non-magnetic phases, to solve this problem, the non-magnetic phase is applied to the bridges of ML IPMSM. Through it, the leakage flux is decreased, and performance improvement of the motor is achieved. In this paper, the electrical parameters, torque, and efficiency are compared using finite element analysis for the motor with and without the DPMM. Finally, to verify the proposed method, the load test is conducted.
Light-Based Anti-Biofilm and Antibacterial Strategies

Biofilm formation and antimicrobial resistance pose significant challenges not only in clinical settings (i.e., implant-associated infections, endocarditis, and urinary tract infections) but also in industrial settings and in the environment, where the spreading of antibiotic-resistant bacteria is on the rise. Indeed, developing effective strategies to prevent biofilm formation and treat infections will be one of the major global challenges in the next few years. As traditional pharmacological treatments are becoming inadequate to curb this problem, a constant commitment to the exploration of novel therapeutic strategies is necessary. Light-triggered therapies have emerged as promising alternatives to traditional approaches due to their non-invasive nature, precise spatial and temporal control, and potential multifunctional properties. Here, we provide a comprehensive overview of the different biofilm formation stages and the molecular mechanism of biofilm disruption, with a major focus on the quorum sensing machinery. Moreover, we highlight the principal guidelines for the development of light-responsive materials and photosensitive compounds. The synergistic effects of combining light-triggered therapies with conventional treatments are also discussed. Through elegant molecular and material design solutions, remarkable results have been achieved in the fight against biofilm formation and antibacterial resistance. However, further research and development in this field are essential to optimize therapeutic strategies and translate them into clinical and industrial applications, ultimately addressing the global challenges posed by biofilm and antimicrobial resistance.
Contour Analysis of Three-Dimensional Peri-Implant Mucosal Model as an Endpoint Analysis of Photofunctionalization Effects on Implant Abutment Materials

Introduction: The objective of this study was to examine the effect of photofunctionalization on the soft-tissue contour formed at the interface of various abutment materials using end-point analyses obtained from the three-dimensional oral mucosal model (3D-OMMs). Methods: Commercially pure titanium (CPTi), alumina-toughened zirconia (ATZ), and yttria-stabilized zirconia (YSZ) made into discs shapes were classified into two groups: UV-treated (PTx) and non-treated (NTx). The materials in PTx groups were exposed to UV light for 12 min. Human gingival fibroblasts and TR146 epithelial cell lines co-cultured on the acellular dermal membrane were used to construct the 3D-OMM. After 4 days of culture, the discs were inserted into the holes prepared within the membrane of 3D-OMMs. The contour formed by the tissue was evaluated after 14 days of culture. Results: The UV treatment of abutment materials resulted in the formation of more non-pocket-tissue types among the PTx group (p = 0.002). Of all materials tested, soft tissue contour around YSZ showed higher scores for the non-pocket type in both non- and UV-treated groups. Conclusions: The non-pocket type of tissue attachment was frequently found in all surfaces modified by photofunctionalization, particularly zirconia. The 3D-OMM can be used to evaluate the biological endpoints of implant surface modifications.
STATISTICAL METHODS

We are interested here in the estimation of the lifetime distribution by using the right censored observations taking into account the probability p that a censored item might contract the interest event after the right censoring. This type of censorship is known in the literature as long-term survival item. We assume that the lifetime follows a log-normal distribution with parameters µ and σ 2 . An EM-algorithm is developed so as to estimate the parameters µ, σ and p. Simulations indicate good accurate and robustness results. The EM-algorithm is then applied to the Cameroonian custom services data set in order to estimate the distribution of the return delays of the Global Position System (GPS). The EM-algorithm leads to accurate results of the parameters involved with smaller mean squared error
Yukon River Hydrological and Climatic changes, 1977-2006

This paper analyses long-term hydrology and climate data over the Yukon River basin. It uses regression analysis to define the relationship between the climate and discharge data over the basin. Discharge at the outlet of the basin shows low runoff in the cold season (November to April), with small variations. Flow is high (28 483-177 000 ft3/s; 807-5012 m3/s) with high fluctuations in the warm season (May to October). The discharge in May has a positive trend (177 000 ft3/s; 5012 m3/s). The mean annual flow is about 227 912 ft3/s (6454 m3/s), with high fluctuations; it has increased by 18 213 ft3/s (or 8 percent) during the study period. Basin air temperature from 1977 to 2006 increased by 3.9 degree F (2.2 degree Celcius) in June and decreased by 10.5 degree F (5.8 degree Celcius) in January. Basin precipitation has negative trend in June (0.6 inch; 15.2 mm) with a confidence over 93 percent. Regression analysis shows a strong and positive correlation between temperature and discharge in May, and a strong and negative correlation between May temperature and June discharge. Precipitation in August and September has strong and positive correlations with basin discharge in September and October.
Aplicación del análisis 3D de elementos finitos en el estudio biomecánico de la dentición de mamíferos. Análisis preliminar en Procervulus ginsburgi (Cervidae, Artiodactyla)

The combination of complex structures and diverse materials, restricts our knowledge of the biomechanics of teeth. In this sense, finite element analysis (FEA) is a method used in engineering and biomechanical studies to estimate the performance and changes produced by regimes of stress and strain in mechanic structures or the human skeleton, as well as in soft tissues. On only rare occasions it is applied to the problem of biomechanical design in animals and even less in fossil groups. In this work, we advance the preliminary results obtained on creating a complete complex 3D finite element model of the tooth of an extinct deer in order to test its functionality and mechanical properties.
Flexibility of Lyapunov exponents for expanding circle maps

Let \begin{document}$ g $\end{document} be a smooth expanding map of degree \begin{document}$ D $\end{document} which maps a circle to itself, where \begin{document}$ D $\end{document} is a natural number greater than \begin{document}$ 1 $\end{document} . It is known that the Lyapunov exponent of \begin{document}$ g $\end{document} with respect to the unique invariant measure that is absolutely continuous with respect to the Lebesgue measure is positive and less than or equal to \begin{document}$ \log D $\end{document} which, in addition, is less than or equal to the Lyapunov exponent of \begin{document}$ g $\end{document} with respect to the measure of maximal entropy. Moreover, the equalities can only occur simultaneously. We show that these are the only restrictions on the Lyapunov exponents considered above for smooth expanding maps of degree \begin{document}$ D $\end{document} on a circle.
Detection and Identification of Cyberattacks and Physical Faults in Multi-Agent Systems: A Distributed Disturbance Decoupling Observer

This article investigates the detection and identification of physical faults in devices and false-data-injection attacks in communication networks for multi-agent systems with event-triggered transmission mechanisms and subject to external periodic disturbances. First, a new detection and identification scheme, including a local disturbance decoupling (LDD) observer and a distributed disturbance decoupling (DDD) observer, is proposed. Then, based on zero-assignment and the rank-deficiency of the transfer function matrix at zeros, a co-design method for the LDD observer and DDD observer is proposed, which enables the decoupling of periodic disturbances from the residuals for detection and identification. This new scheme no longer requires the transmission of control signals from the node being monitored or the exchange of information between its neighbors, significantly reducing the communication overhead and enhancing the system's security. Finally, a simulation based on a multi-two-wheeled trolley system is used to verify the effectiveness of the proposed method.

Microphone Arrays

Such techniques—known collectively as beamforming—have been the subject of intense interest in recent years within the acoustic array processing research community. Unfortunately, such techniques have been largely ignored in the mainstream automatic speech recognition field, although this may rapidly change given the recent release and widespread popularity of the Microsoft Kinect R © platform. The simplest of beamforming algorithms, the delay-and-sum beamformer, uses only this geometric knowledge—i.e., the arrangement of the microphones and the speaker’s position—to compensate for the time delays of the signals arriving at each sensor and then additively combine them. More sophisticated adaptive beamformers minimize the total output power of the array under the constraint that the desired source must be unattenuated. The conventional adaptive beamforming algorithms attempt to minimize a quadratic optimization criterion related to signal-to-noise ratio. Recent research has revealed, however, that such quadratic criteria are not optimal for acoustic beamforming of human speech. Hence, we also present beamformers based on non-conventional optimization criteria, that have appeared more recently in the literature. In particular, recent research has revealed that useful optimization criteria can be devised by attempting to restore the non-Gaussian statistical characteristics present in uncorrupted or “clean” speech. As these characteristics are diminished through the introduction of noise or reverberation, the use of adaptive beamforming techniques to restore the original statistical characteristics reduces the effect of these distortions, and hence improves speech recognition performance.
