Analysis of H ∞ Performance for Multi-Agent Networks

—In this paper, we analyze the H ∞ performance of the first-order continuous-time multi-agent consensus network and that of the corresponding sampled-data network in the presence of external disturbances. Firstly, we build the quantitative relation between the H ∞ performance and the eigenvalues of directed graph Laplacian for the continuous-time multi-agent network. Secondly, we establish the analytic expression of H ∞ performance for the sampled-data multi-agent network, which depends not only the eigenvalues of Laplacian matrix but also the sampling period. It is proved that there exists a unique optimal sampling period such that the sampled-data multi-agent network obtains the optimal H ∞ performance. Furthermore, we show that the H ∞ performance of the sampled-data multi-agent network is not better than that of the original continuous-time multi-agent network. Finally, numerical tests are given on several well-known graphs.
TRADITIONAL AND MOLECULAR DETECTION OF EIMERIA SPP. IN GOAT IN BAGHDAD CITY

: Eimeria is an intracellular protozoan parasite, which infects a wide variety of animals causinga high mortality rate and leadingto economic losses in livestock. Also, it has a relatively high prevalence in Iraq. This study was conducted to estimate the prevalence of Coccdiosis in goat in Baghdad city. Fecal samples collected from 180 goats, from both sexes, different age groups and months during the period from the first of October 2020, to end of March 2020. All fecal samples were examined by microscope and 100 samples that examined microscopically in parasitological lab were taken to the molecular examination and further analyzed using conventional PCR, sequencing and phylogenetic analysis. The microscopic results showed that the total rate of infection was 85 % (153/180). The morphological criteria revealed presence of five species of Eimeria including, E. arloingi , E.alijevi , E. ninakohlykimovae , E. chirstenseni and E. bovis . The highest prevalence was recorded with E. arloingi (33.33%), while E. chirstenseni and E. bovis were revealed the lowest; 11.11% and 4.44%, respectively. No significant differences were showed in concerned the groups of age and sex; however, significant variation was observed between the study months. Regarding PCR, results of 18S rRNA gene showed that 93% of fecal samples were positive togenus of Eimeria . Results for sequencing 13 samples were subjected to homology in the GenBank and Multiple Alignment. This study presented that seven samples were similar to E. arloingi , two samples E. chirstenseni and four samples as E. bovis . Positive isolates were recorded in NCBI with MW577416, MW577417, MW577418, MW577419
Delayed Complications of Emergency Airway Management: A Study of 533 Emergency Department Intubations

Objectives Airway management is a critical procedure performed frequently in emergency departments (EDs). Previous studies have evaluated the complications associated with this procedure but have focused only on the immediate complications. The purpose of this study is to determine the incidence and nature of delayed complications of tracheal intubation performed in the ED at an academic center where intubations are performed by emergency physicians (EPs). Methods All tracheal intubations performed in the ED over a one-year period were identified; 540 tracheal intubations were performed during the study period. Of these, 523 charts (96.9%) were available for review and were retrospectively examined. Using a structured datasheet, delayed complications occurring within seven days of intubation were abstracted from the medical record. Charts were scrutinized for the following complications: acute myocardial infarction (MI), stroke, airway trauma from the intubation, and new respiratory infections. An additional 30 consecutive intubations were examined for the same complications in a prospective arm over a 29-day period. Results The overall success rate for tracheal intubation in the entire study group was 99.3% (549/553). Three patients who could not be orally intubated underwent emergent cricothyrotomy. Thus, the airway was successfully secured in 99.8% (552/553) of the patients requiring intubation. One patient, a seven-month-old infant, had unanticipated subglottic stenosis and could not be intubated by the emergency medicine attending or the anesthesiology attending. The patient was mask ventilated and was transported to the operating room for an emergent tracheotomy. Thirty-four patients (6.2% [95% CI 4.3 – 8.5%]) developed a new respiratory infection within seven days of intubation. Only 18 patients (3.3% [95% CI 1.9 – 5.1%]) had evidence of a new respiratory infection within 48 hours, indicating possible aspiration pneumonia secondary to airway management. Three patients (0.5% [95% CI 0.1 – 1.6%]) suffered an acute MI, but none appeared to be related to the intubation. One patient was having an acute MI at the time of intubation and the other two patients had MIs more than 24 hours after the intubation. No patient suffered a stroke (0% [95% CI 0 – 0.6%]). No patients suffered any serious airway trauma such as a laryngeal or vocal cord injury. Conclusions Emergency tracheal intubation in the ED is associated with an extremely high success rate and a very low rate of delayed complications. Complication rates identified in this study compare favorably to reports of emergency intubations in other hospital settings. Tracheal intubation can safely be performed by trained EPs.
Liouville partial-differential-equation methods for computing 2D complex multivalued eikonals in attenuating media

We have developed a Liouville partial-differential-equation (PDE)-based method for computing complex-valued eikonals in real phase space in the multivalued sense in attenuating media with frequency-independent qualify factors, where the new method computes the real and imaginary parts of the complex-valued eikonal in two steps by solving Liouville equations in real phase space. Because the earth is composed of attenuating materials, seismic waves usually attenuate so that seismic data processing calls for properly treating the resulting energy losses and phase distortions of wave propagation. In the regime of high-frequency asymptotics, the complex-valued eikonal is one essential ingredient for describing wave propagation in attenuating media because this unique quantity summarizes two wave properties into one function: Its real part describes the wave kinematics and its imaginary part captures the effects of phase dispersion and amplitude attenuation. Because some popular ordinary-differential-equation (ODE)-based ray-tracing methods for computing complex-valued eikonals in real space distribute the eikonal function irregularly in real space, we are motivated to develop PDE-based Eulerian methods for computing such complex-valued eikonals in real space on regular meshes. Therefore, we solved novel paraxial Liouville PDEs in real phase space so that we can compute the real and imaginary parts of the complex-valued eikonal in the multivalued sense on regular meshes. We call the resulting method the Liou-ville PDE method for complex-valued multivalued eikonals in attenuating media; moreover, this new method provides a unified framework for Eulerianizing several popular approximate real-space ray-tracing methods for complex-valued eikonals, such as viscoacoustic ray tracing, real viscoelastic ray tracing, and real elastic ray tracing. In addition, we also provide Liouville PDE formulations for computing multivalued ray amplitudes in a weakly viscoacoustic medium. Numerical examples, including a synthetic gas-cloud model, demonstrate that our methods yield highly accurate complex-valued eikonals in the multivalued sense.
Digital Health Literacy and Web-Based Health Information-Seeking Behaviors in the Saudi Arabian Population

Introduction In the evolving landscape of healthcare, the emergence of digital technologies has brought digital health literacy to the forefront. This is especially pertinent given the vast amount of health information available online and the diverse capabilities of individuals to effectively use this resource. Focusing on the Saudi Arabian context, where digital health practices are increasingly integrated into daily life, our study aims to investigate the competencies in digital health literacy and the patterns of online health information seeking among the Saudi population. Methods A quantitative research design was adopted for this investigation. Data were collected through online surveys from a diverse cohort of 2,184 Saudi residents, all above the age of 18 years. The survey was designed to evaluate the participants' ability to find, understand, and use health information obtained from digital platforms. Results Analysis indicates that 63% of the population is proficient in using search engines for health information. However, 37% face challenges in formulating precise health-related inquiries. Additionally, the study identified significant variations in digital health literacy across different genders and age groups, with younger participants generally showing higher literacy levels. Conclusion The results of our study highlight the critical need for specialized educational initiatives in Saudi Arabia aimed at bolstering digital health literacy. This is particularly essential in bridging the gaps observed in different age groups and between genders. By enhancing these key competencies, we can significantly empower individuals to make well-informed health decisions. Such advancements are instrumental in nurturing a society that is both more informed and proficient in managing health-related information in a digital context.
Balance between Pro- and Antifibrotic Proteins in Mesenchymal Stromal Cell Secretome Fractions Revealed by Proteome and Cell Subpopulation Analysis

Multipotent mesenchymal stromal cells (MSCs) regulate tissue repair through paracrine activity, with secreted proteins being significant contributors. Human tissue repair commonly results in fibrosis, where fibroblast differentiation into myofibroblasts is a major cellular mechanism. MSCs’ paracrine activity can inhibit fibrosis development. We previously demonstrated that the separation of MSC secretome, represented by conditioned medium (CM), into subfractions enriched with extracellular vesicles (EV) or soluble factors (SF) boosts EV and SF antifibrotic effect. This effect is realized through the inhibition of fibroblast-to-myofibroblast differentiation in vitro. To unravel the mechanisms of MSC paracrine effects on fibroblast differentiation, we performed a comparative proteomic analysis of MSC secretome fractions. We found that CM was enriched in NF-κB activators and confirmed via qPCR that CM, but not EV or SF, upregulated NF-κB target genes (COX2, IL6, etc.) in human dermal fibroblasts. Furthermore, we revealed that EV and SF were enriched in TGF-β, Notch, IGF, and Wnt pathway regulators. According to scRNAseq, 11 out of 13 corresponding genes were upregulated in a minor MSC subpopulation disappearing in profibrotic conditions. Thus, protein enrichment of MSC secretome fractions and cellular subpopulation patterns shift the balance in fibroblast-to-myofibroblast differentiation, which should be considered in studies of MSC paracrine effects and the therapeutic use of MSC secretome.
Analysing the links between child health and education outcomes: Evidence from NIDS Waves 1 – 4

This paper explores the relationship between child nutrition and schooling outcomes using data from the National Income Dynamics Survey (NIDS) panel data. The recent release of the NIDS panel data from 2008-2015 presents the first opportunity to examine the implications of early child health on human capital accumulation at the national level. This work estimates the relationship between poor nutrition, measured by stunting and obesity in early childhood, and later schooling outcomes among children aged 7 to 14 years. The results suggest that young children who were stunted in Wave 1 go on to complete fewer years of schooling than the children who did not suffer from early undernutrition, not only because they enter school at a later age, but because they progress more slowly through the schooling system. In contrast, no discernible relationship is identified between obesity status and schooling outcomes in young children.
Organizational Commitment: a Review of Conceptual Framework of Three-component Model

In today’s global market place, organizations must utilize their human resources effectively. In a world where competition is fierce, companies are about to realize that their workforce provides a competitive edge and that employee effectiveness is one of the key factors affecting the organization's success. Thus, it is imperative for organizations to ascertain the variables that impact the efficiency and output of their workforce. One of the many variables that can affect their efficacy is organizational commitment. The most devoted, enthusiastic, and faithful employees are the ones who are least inclined to think of leaving their positions. In this context, the concept of organizational commitment becomes a topic of utmost significance. Hence, in this paper, an attempt has been made to understand the conceptual framework of Organizational Commitment as a three-component model. Initially, Organizational Commitment was viewed as a two-component model i.e Affective and Continuance Commitment, later, another component “Normative Commitment” was added after due research.
Trilobatin Possesses Protective Potentials on H2O2-Induced HepG2 Cells by Suppressing Oxidative Stress: Involvement of Nrf2/Keap1 Signal Pathway

: Trilobatin, a natural dihydrochalcone compound, possesses various biological activities. However, few investigations have been carried out on the mechanisms of trilobatin against oxidative stress. To comprehend the effects and mechanism of trilobatin on oxidative stress after hepatic injury, H 2 O 2 -induced HepG2 cells were used in this research. The results indicated that trilobatin enhanced the viability and improved the apoptosis morphology of HepG2 cells induced by H 2 O 2 . The decrease of Mitochondrial Membrane Potential (MMP) and the increase of the antioxidant-related enzymes involving Superoxide Dismutase (SOD), Glutathione Peroxidase (GSH-Px), and Catalase (CAT), as well as the reduced levels of alanine Aminotransferase (ALT) and aspartate Aminotransferase (AST), could be responsible for the protective effect of trilobatin on H 2 O 2 -induced HepG2 cells. Furthermore, the Nuclear erythroid-2 Related Factor 2 (Nrf2)/Kelch-like ECH Associated Protein-1 (Keap-1) pathway was activated by trilobatin in H 2 O 2 -induced HepG2 cells. These results indicated that trilobatin has a strong protective capacity on H 2 O 2 -induced HepG2 cells by inhibiting oxidative stress via Nrf2/Keap1 signaling pathway. This research implies that trilobatin might be a useful antioxidant used to prevent liver diseases caused by oxidative stress.
Design and Evaluation of an Adjustable Compliant Constant-Force Microgripper

Precise control of the manipulating force within an appropriate range is crucial to prevent potential damage to the operating object. However, achieving accurate force control through force feedback is challenging in micro-scale applications. This study presents the design of a quasi-zero stiffness-compliant constant-force microgripper with adjustable force output. The parameters of the constant-force mechanism are designed using a model-based optimization method. By utilizing this mechanism, a compliant microgripper capable of providing adjustable constant-force output is developed to overcome the limitation of traditional grippers that offer only a single constant force. Finite element analysis is performed to simulate the behavior and verify the stability of the constant-force output. Furthermore, an experimental platform is constructed to validate the mechanical properties of the developed microgripper. The experimental results demonstrate that the automatically optimized structural parameters enable the microgripper to achieve the desired constant-force value of 2 N with an adjustable range of 0.15 N. These findings provide a further basis for the application and promotion of compliant constant-force structures.
Band Sampling of Hyperspectral Anomaly Detection in Effective Anomaly Space

This article investigates four issues, background (BKG) suppression (BS), anomaly detectability, noise effect, and interband correlation reduction (IBCR), which have significant impacts on its performance. Despite that a recently developed effective anomaly space (EAS) was designed to use data sphering (DS) to remove the second-order data statistics characterized by BKG, enhance anomaly detectability, and reduce noise effect, it does not address the IBCR issue. To cope with this issue, this article introduces band sampling (BSam) into EAS to reduce IBCR and further suppress BKG more effectively. By implementing EAS in conjunction with BSam (EAS-BSam), these four issues can be resolved altogether for any arbitrary anomaly detector. It first modifies iterative spectral–spatial hyperspectral anomaly detection (ISSHAD) to develop a new variant of ISSHAD, called iterative spectral–spatial maximal map (ISSMax), and then generalizes ISSMax to EAS-ISSMax, which further enhances anomaly detectability and noise removal. Finally, EAS-BSam is implemented to reduce IBCR. As a result, combining EAS, BSam, and ISSMax yields four versions: EAS-BSam, EAS-ISSMax, BSam-SSMAX, and EAS-BSam-SSMax. Such integration presents a great challenge because all these four versions are derived from different aspects, iterative spectral–spatial feedback process, compressive sensing, and low-rank and sparse matrix decomposition. Experiments demonstrate that EAS-BSam and EAS-BSam-SSMax show their superiority to ISSHAD and many current existing hyperspectral anomaly detection (HAD) methods.
A Short Survey and Comparison of CNN-Based Music Genre Classification Using Multiple Spectral Features

The goal of music genre classification is to identify the genre of given feature vectors representing certain characteristics of music clips. In addition, to improve the accuracy of music genre classification, considerable research has been conducted on extracting spectral features, which contain critical information for genre classification, from music clips and feeding these features into training models. In particular, recent studies argue that classification accuracy can be enhanced by employing multiple spectral features simultaneously. Consequently, fusing information from multiple spectral features is a critical consideration in designing music genre classification models. Hence, this paper provides a short survey of recent studies on music genre classification and compares the performance of the most recent CNN-based models with a newly devised model that employs a late fusion strategy for the multiple spectral features. Our empirical study of 12 public datasets, including Ballroom, ISMIR04, and GTZAN, showed that the late fusion CNN model outperforms other compared methods. Additionally, we performed an in-depth analysis to validate the effectiveness of the late fusion strategy in music genre classification.
Creando en casa (Home Studio). Emergencia de nuevas prácticas musicales y subjetividades en Chile

La consolidación de nuevas tecnologías informáticas orientadas a la producción musical, ha resultado en una masificación de la creación en este ámbito. Esto ha llevado a muchos/as músicos/as a trabajar de forma independiente, grabando, produciendo y gestionando su música desde sus propios hogares, lo cual pareciera impactar no solamente la dimensión económica de la actividad de producción musical sino también las formas de vida y organización subjetiva de estas personas. La emergencia de este grupo de creadores/productores ha sido poco explorada en la literatura, por lo cual parece relevante caracterizarlo y explorar estas nuevas prácticas creativas y su posible relación con la construcción de subjetividades que podrían constituirse como particulares de estos actores. Así, el presente artículo busca responder a dos objetivos centrales. En primer lugar, caracterizar multidimensionalmente a productores/as musicales que desarrollan su trabajo creativo principalmente desde estudios caseros (Home Studio). En segundo lugar, se describirán y analizarán prácticas de creación musical distintivas de estos actores, así como posibles emergencias de nuevas subjetividades artísticas que podrían relacionarse con estas nuevas prácticas de creación musical. Para ello, se diseñaron y aplicaron dos instrumentos: una encuesta y entrevistas semiestructuradas. Los resultados sugieren una cierta homogeneidad entre estos actores en cuanto a variables socioeconómicas y demográficas. Algo similar ocurre con las prácticas musicales de formación, producción y distribución de contenidos, así como en la construcción de imaginarios comunes.
THE WWF/GBYP MULTI-ANNUAL BLUEFIN TUNA ELECTRONIC TAGGING PROGRAM (2008-2013): REPERCUSSIONS FOR MANAGEMENT

SUMMARY During the duration of a multi-annual (2008-2013) bluefin tuna electronic tagging program, 130 electronic tags (99 pop-up satellite and 31 internal archival) were deployed in both adult and juvenile fish in the western and central Mediterranean and in the Atlantic coast of Morocco. For the 64 analyzed tuna, weight ranged from 17 up to 250 kg and time at liberty of their tags spanned from 19 up to 391 days. In the western and central Mediterranean, two behavioral patterns (migratory and resident) were observed to co-occur, and from all the tuna that were in the Mediterranean Sea at some point, none crossed over to the eastern Mediterranean basin. Noteworthy, none of the resident individuals left the Mediterranean during the whole tracking period. Furthermore, the occurrence of potential Mediterranean spawners in North Atlantic waters beyond the 45 o W was observed.
Effects of Application of Straw on Organic Carbon in Brown Soil Aggregates by.DELTA.(13)C Method

The field incubation experiment of brown soil incorporated with corn straw with stable isotope(δ13C)was carried out at the experiment station in Shenyang agricultural university.The purpose was to study effects of application of corn straw on distribution of brown soil water-stable aggregates,and explore the dynamic variation of organic carbon in soil water-stable aggregates during straw decomposition.The results showed that application of corn straw not only promoted the formation of2 000μm brown soil waterstable aggregates,and improved aggregate mean weight diameter(MWD),but also significantly increased concentrations of organic carbon in levels of aggregates,increasing with the aggregate level.Brown soil aggregation capability gradually weakened with incubation time,which led to water-stable macro-aggregates break into micro-aggregates and MWD decline.The concentrations of total/new organic carbon showed a downward trend in macro-aggregates,while it showed a upward trend in micro-aggregates.The total soil organic carbon and organic carbon in aggregates showed a significant positive correlation at P0.05.
