Evaluation of Antibacterial and Antibiofilm Properties in Australian Native Plant Endophyte Metabolites for Wound care Applications
Authors: Firoozbahr Meysam , Palombo Enzo A. , Kingshott Peter , Zaferanloo Bita
Published: November 2023

The wound management sector has attracted considerable attention due to the increasing challenge posed by antimicrobial resistance (AMR) and the specialized care required for chronic wounds. Effective wound care involves selecting appropriate dressings tailored with antimicrobial agents to prevent bacterial infection. Among various types of wound dressings, fibers and electrospun fibers, with their unique characteristics, have emerged as innovative new materials. However, the rise of AMR necessitates the exploration of new antimicrobial agents for wound dressings, particularly for addressing bacterial pathogens like methicillin-resistant Staphylococcus aureus (MRSA). Endophytic fungi, known for producing diverse bioactive compounds, including novel antibacterial agents, represent a promising source of such new agents. This study tested thirty-two endophytic fungi from thirteen distinct Australian native plants for their antibacterial activity against S. aureus, the most common wound-associated bacteria. Ethyl acetate (EtOAc) extracts from fungal culture filtrates exhibited inhibitory effects against both methicillin-sensitive S. aureus ATCC 25923 and MRSA strains M173525 and M180920. DNA sequence analysis was employed for fungal identification, with EtOAc extracts from the most active sample, EL 19 (Chaetomium globosum), selected for further bactericidal and antibiofilm testing against the chosen bacteria. Biofilm of S. aureus ATCC 25923 was reduced by 55% by EtOAc extracts of EL 19 at 1/2 × MIC. To demonstrate the potential application in wound dressing materials, three different concentrations of the extract were incorporated into Polycaprolactone fiber mats through electrospinning, with resultant inhibition of S. aureus ATCC 25923 being observed. This research underscores the potential of endophytic fungi from Australian plants as sources of substances effective against common wound pathogens. Further exploration of the responsible compounds and their mechanisms could facilitate the development of wound dressings effective against MRSA and innovative biofilm-resistant electrospun fibers, contributing to the global efforts to combat AMR.

Ἐνδημοῦσα σύνοδος: nuevas fuentes para la redefinición de una institución eclesiástica exquisitamente oriental
Authors: Acerbi Silvia
Published: November 2023

En nuestra contribución analizaremos la génesis y posterior desarrollo, en el marco de las controversias doctrinales de los siglos V y VI, de una institución eclesiástica especifica de la iglesia de Constantinopla, el sínodo ἐνδημοῦσα, inicialmente una reunión de obispos subordinada al azar de los encuentros, luego un concilio permanente formado por los obispos presentes en la capital de la Pars Orientis del Imperio (del que los mismos obispos a menudo se servían como instrumento para dirimir conflictos de tipo teológico o jurisdiccional), y finalmente una institución de la Iglesia Imperial. Utilizando una serie de fuentes hasta ahora no tomadas en consideración por los estudiosos que se han dedicado al tema, y a la luz de las más recientes contribuciones sobre el episcopado tardoantiguo, analizaremos su utilización político-eclesiástica por parte del poder imperial y de la jerarquía religiosa en los enfrentamientos entre los titulares de las principales sedes supra-metropolitanas del Oriente y con los poderes laicos.
“The Abomination of Desolation”: Eastern Christian Apocalyptic Literature and the Symbolic Construction of Islam
Authors: Grypeou Emmanouela
Published: November 2023

This article focuses on the Christian apocalyptic literature that was produced as a specific reaction to the emergence of Islam and the consolidation of the Islamic rule in the Eastern provinces of Byzantium. The discussion examines how these texts re-cycled, used and manipulated long established cultural stereotypes, biblical exegetical topoi and traditional apocalyptic motifs in order to construct an image of the Muslims as the symbolic “Other”.

Autores católicos clericales y la cristalización de la memoria histórica de la 1ª GM en el discurso particularista libanés, 1918-1922
Authors: WALKER Dennis
Published: November 2023

Para los escritores libaneses clericales, ligados a Occidente por el francés y el latín, la masacre de la I Guerra Mundial evidenció que las ideologías pro-católica y secularista habían resultado fallidas para mantener la paz y la prosperidad en Europa. Los clericales se sentían atados al destino de los estados europeos, cuyo secularismo odiaban al vincularse estéticamente a las lenguas latinas. Éstos también sintieron la necesidad de un protector contra algunos musulmanes después de que la hostilidad turca en Monte Líbano destruyera la antigua ideología con tendencia al desarrollo del multisectarismo otomano.

Published: November 2023

Delayed ejaculation (DE) is rare disorder of sexual function reported to affect between 1-5% of men. However, due to the lack of a standard definition, the true prevalence, incidence, and treatment trends remain unclear. Herein, we assess the trends in prevalence and incidence of DE diagnosis as well as the medications and comorbidities in men when diagnosed with DE and treatment patterns using a large claims database. The TriNetX Diamond database was queried to identify adult males diagnosed with DE. Prevalence was determined by comparing men with a diagnosis of DE to the total population of men evaluated in the inpatient, outpatient, and emergency settings in six-month intervals within the database. Similarly, incidence was determined by comparing men with a new diagnosis to the total population of men without a previous diagnosis. Pharmacotherapy rates were calculated by comparing the number of men receiving a prescription to the total number of men in one-year intervals. We identified 23,164 men with a diagnosis of DE. In the final period, 2,747 (0.02%) men were diagnosed with DE and 1,375 (0.01%) received a new diagnosis of DE, with prevalence and incidence increasing over time. The most common medications prescribed in the final period were testosterone (9.5%), bupropion (6.6%), and buspirone (2.3%). Additionally, 916 (19.4%) received any prescription, with the rates of these medications increasing consistently over time. Delayed ejaculation is rarely diagnosed but has increasing prevalence. Rates of pharmacotherapy remain low. Further work is needed to investigate first-line medical therapy if behavioral modifications and psychotherapy fail.
Asymmetrical Responses of the ITCZ to Symmetrical Thermal Forcings at Different Latitudes
Authors: Ma Xinyu , Huang Weichong , Zhao Shuyun , Zhang Hua , Wang Wuke , Wang Lunche
Published: November 2023

Meridional shifts of the intertropical convergence zone (ITCZ) in response to tropical or extratropical forcings have been investigated widely within an emerging energy framework. While few studies concerned the forcings of different spatial patterns. This work explores the dependence of the ITCZ response on the patterns of thermal forcings, which are hemispherically antisymmetric and zero in global mean, using the Community Earth System Model coupled with a slab ocean. Results show that the magnitudes of ITCZ displacements caused by mid-latitude perturbations are larger than their low-latitude counterparts, though the perturbation amounts are the same in hemispherically average. It is found mid-latitude perturbations cause more cross-equatorial atmospheric energy transport (AET) and moisture transport, the upper and lower branches of an anomalous Hadley cell. The reason lies further in the different mechanisms of precipitation response to low- and mid-latitude thermal perturbations. That is when perturbations are added in tropics, evaporation and clouds share the responses, limiting the magnitude of either one; while when perturbations are added in mid-latitudes, baroclinicity change allows local evaporation and tropical clouds to respond fully. Results also show that the zonal mean precipitation responses have asymmetric components even though the warming and cooling are symmetric; that is the increase of precipitation in the warmed hemisphere is more poleward than the decrease of precipitation in the cooled hemisphere. This is especially true when the mid-latitudes of the southern hemisphere (SH) are warmed. The phenomenon is a manifestation of the positive feedback of precipitation to the anomalous Hadley circulation. And that the asymmetric components of precipitation response are greater in the case of warming SH than those in the case of warming the northern hemisphere is attributable to the offset of AET by transient eddy in the latter case.
A cyclic random motion in $\mathbb{R}^3$ driven by geometric counting processes
Authors: Iuliano Antonella , Verasani Gabriella
Published: November 2023

We consider the random motion of a particle that moves with constant velocity in $\mathbb{R}^3$. The particle can move along four directions with different speeds that are attained cyclically. It follows that the support of the stochastic process describing the particle's position at time $t$ is a tetrahedron.We assume that the sequence of sojourn times along each direction follows a geometric counting process (GCP). When the initial velocity is fixed, we obtain the explicit form of the probability law of the process $\boldsymbol{X}(t) = (X_1(t);X_2(t);X_3(t))$, $t > 0$, for the particle's position. We also investigate the limiting behavior of the related probability density when the intensities of the four GCPs tend to infinity.Furthermore, we show that the process does not admit a stationary density.Finally, we introduce the first-passage-time problem for the first component of $\boldsymbol{X}(t)$ through a constant positive boundary $\beta > 0$ providing the bases for future developments.

Published: November 2023

The present study aimed to investigate the decolorization of various commercial dyes through bioinformatics analysis, utilizing techniques such as molecular docking, molecular dynamics simulation, and Molecular Mechanics Poisson-Boltzmann Surface Area (MMPBSA). These analyses were conducted on different commercial dyes to evaluate their potential for biodegradation. In this study, four commercial dyes, namely acid orange 7, cresol red, methylene blue, and malachite green, were selected as potential targets for degradation by azoreductases (AzrBmH21, AzrBmH22/3, and AzrBmH24/5) derived from Bacillus megaterium H2. The prediction of ligand binding or catalytic sites for AzrBmH21, AzrBmH22/3, and AzrBmH24/5 was performed using a machine learning algorithm based on the Prank Web and DeepSite chemoinformatic tool. The analysis revealed that several amino acids of AzrBmH2 interacted with the tested dyes, indicating the presence of distinct ligand-binding sites for AzrBmH2-dye complexes. The binding affinity for AzrBmH21, AzrBmH22/3, and AzrBmH24/5 ranged from − 9.4 to -5.5 kcal/mol, -9.2 to -5.4 kcal/mol, and − 9.0 to -5.4 kcal/mol, respectively. Each complex was stabilized by a minimum of 0–5 hydrogen bonds. MD simulations revealed stable AzrBmH2-dye complexes (with RMSD 0.15–0.42 nm, RMSF 0.05–0.48 nm, Rg 1.75–1.88 nm). MMPBSA calculations indicated that the AzrBmH2-dye complexes, except for AzrBmH2-malachite green, exhibited the lowest binding energy (-191.05 ± 7.08 to 314.19 ± 6.88 kcal/mol). The AzrBmH2-malachite green complex showed a prevalence of hydrophobic interactions (-268.25 ± 12.25 to -418.92 ± 29.45 kcal/mol) through van der Waals forces. This study highlights the potential role of enzymes, specifically azoreductases from Bacillus megaterium H2, in predicting the decolorization of commercial dyes. These findings contribute to our understanding of enzyme mechanisms in bioremediation and for biotechnological applications.
Hydrodynamical Study of Couple Stress Fluid Flow in a Linearly Permeable Rectangular Channel Subject to Darcy Porous Medium and No-Slip Boundary Conditions
Authors: Ishaq Muhammad , Rehman Saif Ur , Zahid Muhammad
Published: November 2023

In this paper, the study investigates the issue of the creeping flow of a non-Newtonian couple stress fluid through a linearly porous walled slit within a Darcy porous medium. The well-established approach, the Inverse Method approach, was employed to attain the precise solution of the governing equations. The inverse technique is utilized to transform the momentum equations into stream functions. The physical parameters are all computed: longitudinal velocity, transverse velocity, fractional reabsorption, leakage flux, axial pressure, volume flow rate, and mean pressure. The data was also graphed, indicating that the initial flow rate affects longitudinal velocity but not transverse velocity. The initial flow rate significantly impacts streamlines; as the flow rate rises, the streamlines become straighter and more uniform. Physical quantities are also influenced by permeability and the couple stress parameter. Backward flow occurs at the slit’s end due to the porosity parameter. The fluid flow in kidney-diseased renal tubules is the main focus of this study. Some fibrous materials, fatty substances, and solid waste particles, among other things, may become suspended in the tubule channel and in the wall’s pores as a result of illnesses, leading to biofouling and porosity filling in the slit, respectively.

Authors: Sun Xiujuan , Wei Guohui , Zhang Shan , Li Yuepeng , Wang Chuanjiang
Published: November 2023

In order to improve the recognition and prediction accuracy of automatic classification of ECG signals, this paper proposes an arrhythmia classification method based on SECNN-LSTM. First, ECG signal is preprocessed, and the data is resampled for the problem of data imbalance, then the SECNN-LSTM network model is built. The spatial features of the signal are extracted by SECNN model and the front and back dependencies of the feature information are captured by LSTM model. The method has been tested and verified on the MIT-BIH Arrhythmia Database, and compared with other traditional arrhythmia classification method. The accuracy, precision, sensitivity, specificity and F1 value of the model have been improved to different degrees, and the average accuracy of the model has reached 98.70%. The experimental results show that this method can efficiently and accurately identify normal beats and four common types of arrhythmia diseases.

Published: November 2023

Background and aims: Currently, there is a pressing need to study and improve both water and nitrogen (N) use efficiency (WUE and NUE). Surprisingly, this topic has not been adequately documented in recent literature, particularly within the context of intercropping systems. This study aims to assess the simultaneous changes in WUE and NUE through the implementation of rainfed pea-barley intercropping compared to their respective monocultures.
Methods: Field trials were conducted over two growing seasons at four experimental sites characterized by varying soil and pedoclimatic conditions. WUE and NUE were measured in monoculture and intercropping involving pea and barley.
Results: Our findings indicate that pea-barley intercropping had a more pronounced advantage over monoculture in terms of grain yield (+61%) and yield quality (+83%) compared to plant biomass (+35%), except for the site under dry conditions. Additionally, the results show that under higher rainfall conditions, intercropping exhibited the highest NUE values (5.07 kg grain N kg-1 soil N at sowing), while the highest WUE values (1.40 kg m-3) were observed under low-rainfall. Quantifying the relationship between WUE and NUE indicated a positive interaction for intercropping (r2 = 0.61, p ≤0.001) and pea monocrops (r2 = 0.36, p ≤0.01), but only when considering dry biomass at flowering stage.
Conclusion: These advantages of pea-barley intercropping can be attributed to the optimized-use of N and water resources, considering their contrasting co-limitation under semiarid conditions.

Authors: Savanur Mitravinda , Jain Tanushree , MK Ashika , K Safiya Arfain
Published: November 2023

Background: In India, obesity has been a growing concern. The coexistence of obesity and sarcopenia can have serious health implications.
Objectives: The objectives of the present study were to find out the prevalence of sarcopenia in obese and non-obese individuals and identify the factors influencing sarcopenia in them.
Methodology: We selected 603 adults aged between 40 to 80 years residing in urban Bengaluru. We measured their weight, height, waist circumference, calf circumference and hand grip strength. We also used short physical performance battery and 24-hour recall to study their muscle function and nutrient intake respectively. South Asian guidelines were used to diagnose sarcopenia.
Findings: One-third of the participants had sarcopenia. We found 20.6% (126) and 10.2% (62) individuals with sarcopenic obesity and non-obese sarcopenia respectively. Multinominal regression analysis indicated that age, diabetes, higher energy intake increased the odds of having sarcopenia in both obese and non-obese groups (p < 0.05). Dietary protein intake was seen to offer protection against sarcopenia in both obese and non-obese groups (p < 0.05). Individuals with family history of arthritis and females increased the odds of sarcopenia in obese and non-obese individuals respectively (p < 0.05). On the other hand, dietary calcium and fat intake were protective against sarcopenia in obese and non-obese individuals respectively (p < 0.05).
Conclusion: Sarcopenia was seen to be more prevalent in the obese group. Efforts need to be made to include screening for sarcopenia in regular clinical assessment. Early diagnosis along with nutritional modification may aid in prevention and treatment of sarcopenia.

Published: November 2023

Two new species of Urocleidoidesare described from the gills of Pseudanos trimaculatus (Characiformes: Anostomidae) from the coastal drainages of the Eastern Amazon, Brazil. Urocleidoides itabocaensis n. sp. is characterized by having a sclerotized, tubular, sigmoid male copulatory organ (MCO), a circular sclerotized tandem brim associated with the base of the MCO; an accessory piece articulated with the MCO, V-shaped, divided into two subunits, distal subunit spoon-shaped; and a vaginal pore dextroventral with opening marginal. Urocleidoides omphalocleithrum n. sp. is characterized by presenting a C-shaped or sigmoid MCO; accessory piece articulated with the MCO, L-shaped, divided into two subunits, distal subunit gutter-shaped vaginal pore dextroventral with opening marginal; and ventral bar broadly V-shaped, with anteromedial projection. Molecular phylogenetic analysis based on partial 28S rDNA and COI mtDNA genes indicate that U. itabocaensis n. sp. and U. omphalocleithrum n. sp. are closely related and appear as a sister group to the other species (U. paradoxus, U. digitabulum and U. sinus) that parasitizing anostomid fishes. This study represents the first record of monogenoids from the gills of P. trimaculatus for the Eastern Amazon.
Object Detection driven Composite Block MotionEstimation Algorithm for High-FidelitySurveillance Video Coding
Authors: Pal Arup Kumar , Biswas Bhaskar , Jichkar Mihir Digamber , Jena Adarsh Nandan , Kumar Manish
Published: November 2023

The accurate estimation of motion in video sequences is a critical task in various computer vision applications, such as video compression, video surveillance, and autonomous navigation. Block matching is a popular method for motion estimation that involves finding the best match between blocks of pixels in consecutive frames. However, using a single block matching algorithm for the entire frame may not be efficient, especially when dealing with dynamic scenes containing moving objects. In this paper, we propose a novel approach for motion estimation using composite block matching algorithms based on object detection. Our method first detects the moving objects in the video frame using a deep learningbased object detection algorithm. Then, we use one block matching algorithm for the area of the frame where the objects are detected, and another block matching algorithm for the remaining part of the frame. The rationale behind using two different algorithms is that the area containing the objects usually has more complex motion patterns and may require a more sophisticated and rigorous algorithm than the rest of the frame. Our results show that the proposed method achieves higher accuracy and faster processing time compared to any single motion estimation methods. The composite block matching algorithm provides more accurate motion estimation in the object regions, leading to better object tracking and less motion artifacts. Moreover, the use of a simpler block matching algorithm for the non-object regions reduces computational overhead, making the overall process more efficient for compression surveillance video.

Published: November 2023

The study aims to analyze the effect of insourcing initiatives on cost savings within organizations. The data was analyzed using the regression technique with the aid of Special Package for Social Science (SPSS). The regression result shows that cost-related insourcing and non-cost related insourcing have a significant effect on organizational cost savings. The study concluded that cost-related and non-cost-related insourcing are the main determinants of organizational cost savings. As a result, the study recommended that management should increase the level of non-cost-related insourcing, like insourcing product development functions to develop products more tailored to the needs of the customers, insourcing manufacturing operations to improve quality, insourcing marketing functions for better control of brand images, will result in more organizational saving.

Published: November 2023

In this study, we present the results of theoretical calculations related to heat transfer in materials subjected to laser radiation, with a focus on Z-scan experiments. Utilising a computational approach, we employ explicit difference methods to model the temperature distribution in three-dimensional hexahedral samples of varying sizes, including [4x4x2]mm, [5x5x2]mm, and [6x6x2]mm. The simulations incorporate the effects of three distinct types of pulse lasers, each with duration of 10 (ns), 100 (ps), and 100 (fs). Laser parameters are tailored such that they yield a peak on-axis irradiance of 5 (GW/cm2).
The temperature distribution within the samples, denoted as T(x, y, z, t), is calculated using our novel laser heat source model, specifically designed for the simulated problem. This research is facilitated by our computational program, Z-lambda, which enables the simulation of thermal processes not only during but also after Z-scan experiments. The computed results reveal that analysing thermal aspects in Z-scan experiments necessitates considering factors such as laser pulse duration, sample geometry, laser repetition time, sample heating, and the experimental environment.
Our findings provide valuable insights into the intricacies of heat transfer during and after Z-scan experiments, shedding light on the interplay between laser parameters, sample properties, and thermal responses. This work enhances our understanding of thermal processes in the context of laser-induced heating, offering significant implications for the design and interpretation of Z-scan experiments.
Non-Lambertian surfaces and their challenges for visual SLAM
Authors: Pyykölä Sara , Joswig Niclas , Ruotsalainen Laura
Published: November 2023

Non-Lambertian surfaces are special surfaces that can cause specific type of reflectances called specularities. These specularities pose a potential issue in industrial SLAM, where non-Lambertian surfaces are aplenty naturally, as specularities can violate two common and basic assumptions of computer vision, namely the brightness and colour constancies, which assume that the brightness and colour of same real-world points stays constant across images. The performance of industrial navigation systems can as such be hindered by specularities.

This paper reviews fundamental surface reflectance models, modern state-of-the-art computer vision algorithms and two public datasets, KITTI and DiLiGenT, related to non-Lambertian surfaces' research. A new dataset, SPINS, is presented for the purpose of studying non-Lambertian surfaces in navigation and an empirical performance evaluation with ORB SLAM 3 is performed on the data. The paper concludes with discussion about the results of empirical evaluation and the findings of the survey.
Finiteness of Cohomology for Pro-locally Proper Maps
Authors: González Javier Sánchez
Published: November 2023

We introduce a notion of proper morphism for schematic finite spaces and prove the analogue of Grothendieck's finiteness theorem for it. As a corollary, this result generalizes the class of morphisms of schemes for which the conclusion of the aforementioned Theorem holds. The techniques we employ, which further develop the theory of schematic spaces and proschemes, are ultimately founded on descent properties of flat epimorphisms of rings that are applicable in other situations in order to weaken finite presentation requirements.

R-codes for Calculating Fluctuation Assay Results and 95% Confidence Intervals Based on Ma-Sandri-Sarkar Maximum Likelihood
Authors: Abdalla Ola , Walker Cameron
Published: November 2023

The Luria-Delbrück fluctuation assay is an essential experiment in calculating mutation rates, especially in genetic and mutation research. Its reliability and accuracy have made it the go-to method for numerous researchers. In this article, we provide R-codes that statistically analyze the assay results more easily and offer the most challenging codes for calculating 95% confidence intervals based on the gold standard method “Ma-Sandri-Sarkar Maximum Likelihood.” Recently, the maximization of the likelihood function through optimization functions in R can be a challenging task. The recursive format of the likelihood function is known to cause memory stack issues. Our findings indicate that utilizing a non-recursive version of the function can increase the tractability of the maximization process. With these codes, future scientists can unlock valuable statistical insights related to the biological mechanisms that drive genetic variation and can, therefore, contribute to developing novel therapeutic interventions and innovative solutions to various biological and medical challenges.

Published: November 2023

Asia Pacific is the region with the highest number of losses in the world. While Indonesia ranks fourth in the number of frauds, it has the highest increase in frauds based on the CPI index. This study aims to examine employee fraud triggered by the six components of the fraud hexagon. This study tries to develop the hexagon fraud element by adding power distance elements and using ethical values as a moderating variable. This study conducted a survey of 351 respondents. Using a purposive sampling method, the heads of funds, heads of credit, heads of treasurers and heads of accountants were selected as respondents in 128 rural banks in Bali. PLS displays an adjusted R2 value of 0.331. Not all elements of the fraud hexagon are proven to influence fraud. Only pressure, opportunity, rationalization, and ego affect employees in committing fraud. Meanwhile, power distance as an additional element of the fraud hexagon can increase fraud. Ethical values can become an anti-fraud strategy in reducing employee pressure and ego in committing fraud. The results of this study will provide input for rural bank managers to anticipate factors that increase employee fraud and increase the role of ethical values in suppressing employees’ desire to commit fraud.

Published: November 2023

City competitiveness is a complex product of local and international conditions, local characteristics, social and economic superstructure, and the actions of individual companies. Although many scientific studies have examined the country’s and urban competitiveness, the competitiveness of port cities still needs to be assessed comprehensively, taking into account their crucial economic role. The purpose of this paper is to evaluate the competitiveness and economic security of the Baltic port cities (Klaipėda, Riga, and Tallinn). Statistical processing and multi-criteria evaluation methods (SAW, COPRAS, and TOPSIS) were chosen to achieve this goal. The comparative analysis showed that the population change in port cities is not significant for the final result of the competitiveness assessment, and the unemployment rate in port cities is lower than in the country. The assessment of the competitiveness of port cities from the point of view of economic security shows (after checking such indicators as unemployment rate, company income, and infrastructure) that Tallinn is the most competitive port city according to the three multi-criteria evaluation methods, while Klaipėda is the least competitive. The assessment was carried out in three stages to monitor changes in the situation of port cities, compared to changes in a certain indicator and the costs of timely solutions or the improvement of the city’s position in relation to other cities.
