A pig tracking algorithm with improved IOU-tracker

As one of the key technologies for pig behavior recognition, multi-target tracking is of great significance in the field of automated monitoring of large-scale pig farms. Aiming at adhesion and occlusion problems between pigs, this paper proposes an improved IOU-Tracker pig tracking algorithm suitable for real breeding scenarios, and combined with the YOLOv5s network to achieve real-time pig tracking. In the tracking algorithm, the strategy of preferential matching between the Narrow Rectangle of IOU and the Priority Matching by IOU Value to solve the adhesion problem of pigs; it integrates an algorithm of Location Prediction in several frames to predict the reproduced position of the lost target within a certain number of frames, effectively reducing the change of the target ID due to factors such as occlusion and detection frame jitter. Construct pig tracking datasets under different perspectives and scenarios, a total of 7 pig videos, and use the MOT benchmark as the multi-target tracking evaluation standard, also verify on the public dataset of MOT16 and the self-built pig data set. Experiments show that on the public data set MOT16, the algorithm in this paper has reached 48.57% and 88.67% on the MOTA and MOTP indicators respectively; the IDSW times are only 297, which is 59.3% and 49.3% lower than the IOU-Tracker and DeepSort algorithms respectively; On the self-built pig data set, the MOTA index of the algorithm in this paper reached 97.60%, which is 0.37% and 9.39% higher than the IOU-Tracker and DeepSort algorithms respectively; MOTP reaches 98.38%, which is 0.1% and 2.2% higher than IOU-Tracker and DeepSort algorithms respectively; IDSW times are 40 times and 34 times lower than IOU-Tracker and DeepSort respectively; And the FPS reaches 33, which can meet the real-time tracking requirements. Therefore, the algorithm in this paper has a good effect on pig tracking in pig farms, and provides a technical basis for the automatic monitoring of large-scale farms.
Insiders, Outsiders and Performance of Vietnamese Firms

The consensus in the finance literature is that a large proportion of inside ownership (defined as greater than 5% share ownership by non-institutional holders, managerial holdings, founding family holdings, cross-shareholdings by affiliated firms and ownership by creditors) tends to be associated with more unsatisfactory performance (as measured by ROE or ROA) when compared to firms with lower inside ownership, all else equal. However, this need not be the case if insiders act as monitors of the firm and have the same interest in returns as outsiders. Ownership structure and firm level financial performance have not been widely studied in Vietnam. Using data from 729 listed firms in Vietnam for 2018, we test the hypothesis that greater insider ownership has a negative impact on firm performance. We found that Vietnam's insiders play a monitoring role, exercising their relative power to ensure the firm's profitable functioning. These findings are inconsistent with research on Japanese groupings, as well as other findings. The Vietnamese stock market does not appear to be negatively affected by insider influence; indeed, insiders appear to act as positive monitors.

Space-Time Discontinuous Galerkin Methods for Convection-Diffusion Problems - Application to Wet-Chemical Etching

In this thesis we discuss space-time discontinuous Galerkin (DG) finite element methods for transport phenomena in incompressible flows. The methods, which simultaneously discretize the equations in space and time, provide the necessary flexibility to deal with time deforming meshes and mesh adaptation. In particular, we discuss space-time DG methods for the advection-diffusion equation, which governs the concentration of the acid fluid, and for the incompressible Navier-Stokes equations to model the flow of the acid fluid inside and outside the etching cavity. We provide a detailed theoretical analysis of the stability of the newly developed methods, as well as some simple numerical tests to investigate the accuracy of the methods.
Factors affecting intention and attitude toward sidewalk autonomous delivery robots among online shoppers

ABSTRACT Sidewalk autonomous delivery robots (SADRs) are a new last-mile delivery service. The present study aims to identify the factors impacting the adoption of SADRs among Iranian online shoppers. To this end, based on consumer coproduction theory and technology readiness (TR), this paper combined individual factors, socialized factor, and risk factors. A total of 287 respondents were surveyed using an online questionnaire, and the partial least squares structural equation modelling (PLS-SEM) was employed to model the data. The modelling results revealed that attitude, innovativeness, and optimism had positive impacts on the intention of consumers to use delivery robots. Furthermore, optimism and environmental concern had a positive impact on attitude, while the need for human interaction, performance risk, and delivery risk had negative impacts. However, no significant relationship was found between innovativeness and attitude. The results of the present study provide important theoretical and practical suggestions to marketers and delivery service provides.
Physical modelling of EPB TBM in dry sand and greenfield conditions

Abstract This paper presents the results obtained during the first stage of a large experimental project based on the so-called ‘Earth Pressure Balanced Shield’ (EPBS) method adapted to tunnelling in soft ground. In the first part, the details of a 1 g laboratory model of EPBS specially improved within the framework of this project are presented. In particular, the new elements of the experimental setup, its instrumentations, the machine control, the preparation of the soil mass model are detailed. In the second part, the results obtained from this new EPBS model for two excavation tests, carried out in purely frictional soil mass (dry fine silica sand) and greenfield conditions (without neighbouring structures), are presented. The analysis concerns both soil surface and subsurface displacements, vertical and horizontal stress evolution in the ground when the Tunnel Boring Machine (TBM) progresses. It confirms that the highly sophisticated design of the machine allows to simulate the 3D excavation process closely, and to reproduce kinematic phenomena in the ground being in good agreement with those observed in the practice. In the case of the steady state excavation imposed during the tests, the extension of the TBM impact zone could also be identified based on the measured stress and strain variations of the ground.
Ingraining Polio Vaccine Acceptance through Public Service Advertisements in the Digital Era: The Moderating Role of Misinformation, Disinformation, Fake News, and Religious Fatalism

Recently, misinformation and disinformation, as well as fake news, have become global threats to public health owing to their role in spreading viral health hazard information. The growing explosive religious fatalistic views presented on social media and widespread misinformation, disinformation, and fake news can result in detrimental outcomes in adopting protective behavior. The moderating implications of misinformation and religious fatalism can be severe, leading to adverse effects on polio vaccine acceptance. Consequently, this research provides brief empirical evidence on the efficacy of risk communication strategies to address polio vaccine reluctance in a digital age landscape, an area that remains understudied. This research argues that the spread of misinformation, disinformation, fake news, and religious fatalism is not solely the bane of the polio vaccine, but rather represents the absence of risk communication strategies. The study opines that polio vaccine acceptance can be improved using risk communication strategies. Recognizing these risk factors and counter-risk communication strategies, this research tested a theoretical model using the cross-sectional survey design. Overall, data was collected from 2160 parents with children aged below five years. The results, based on structural equation modeling, revealed that public service advertisements are an effective tool to counter the inverse impacts of misinformation, disinformation, fake news, and religious fatalism. Furthermore, the inverse moderating role of misinformation, disinformation, fake news, and religious fatalism has been verified to potentially diminish polio vaccine acceptance. These results suggest that healthcare providers must identify and address all forms of digitally disseminated information that encumbers public health behaviors. Accordingly, this research recognized the utilization of evidence-based strategic communication campaigns to cultivate and encourage the literacy necessary to counter health hazard information, including misinformation. This study’s findings will benefit health and other concerned authorities in utilizing strategic communication on different media platforms to reduce or eradicate the polio endemic.
Assessment of Diversity among Important Brinjal (Solanum melongena) Cultivars Using Morphological Markers

Background. Solanum melongena is a medicinally important vegetable crop that belongs to the family Solanaceae, which is cultivated worldwide. Methodology. In the present study, 22 eggplant varieties from the different ecogeographical regions were evaluated for nine quantitative and twenty-two qualitative morphological characters. A significant divergence was observed in all characters and wide regional variations for plant characteristics, flower, and fruit characteristics. Principle component analysis (PCA) was performed using PAST3 software to determine the relationship among eggplant accessions. Results. The principal component analysis showed that the first two principal component axes explained 97.17% of the total multivariate variation. Cluster analysis using the Unweighted Pair Group Method of Arithmetic Means (UPGMA) grouped the 22 eggplant accessions into two main clusters based on similarities in morphological characteristics. The study showed that the Solanum melongena accessions belonging to Pakistan and other geographical regions of the world possess marked variation in fruit weight, fruit shape, fruit color, leaf spine, number of locules in fruit, plant height, and flower color. Conclusion. Based on morphological diversity, the best cultivars of eggplant that show better yield can be selected for farmers.
Magnetic power spectra from Faraday rotation maps REALMAF and its use on Hydra A

We develop a novel maximum-a-posteriori method to measure magnetic power spectra from Faraday rotation data and implement it in the REALMAF code. A sophisticated model for the magnetic autocorrelation in real space permits us to alleviate previously required simplifying assumptions in the processing. We also introduce a way to treat the divergence relation of the magnetic field with a multiplicative factor in Fourier space, with which we can model the magnetic autocorrelation as a spherically symmetric function. Applied to the dataset of Hydra A north, we find a power law power spectrum on spatial scales between 0.3 kpc and 8 kpc, with no visible turnover at large scales within this range and a spectral index consistent with a Kolmogorov-like power law regime. The magnetic field strength profile seems to follow the electron density profile with an index α = 1. A variation of α from 0.5 to 1.5 would lead to a spectral index between 1.55 and 2.05. The extrapolated magnetic field strength in the cluster centre highly depends on the assumed projection angle of the jet. For an angle of 45 ◦ we derive extrapolated 36 μG in the centre and directly probed 16 μG at 50 kpc radius.
Ionized gas outflow in the isolated S0 galaxy NGC 4460

We used integral-field and long-slit spectroscopy to study a bright extended nebulosity recently discovered in the isolated lenticular galaxy NGC 4460 during an Hα survey of nearby galaxies. An analysis of archival Sloan Digital Sky Survey, GALEX and Hubble Space Telescope images indicates that current star formation is entirely concentrated in the central kiloparsec of the galaxy disc. The observed ionized gas parameters (morphology, kinematics and ionization state) can be explained by a gas outflow above the plane of the galaxy, caused by star formation in the circumnuclear region. Galactic wind parameters in NGC 4460 (outflow velocity, total kinetic energy) are several times smaller, compared with the known galactic wind in NGC 253, which is explained by the substantially lower total star formation rate. We discuss the cause of the star formation processes in NGC 4460 and in two other known isolated lenticular (S0) and elliptical (E) galaxies of the Local Volume: NGC 404 and 855. We provide evidence suggesting that the feeding of isolated galaxies by intergalactic gas on a cosmological time-scale is a steady process without significant variations.
Polyphenols Content, Chelating Properties
and Adsorption Isotherms and Kinetics of Red
and Yellow Pomegranate Peels (Punica granatum L.)
Towards Lead (II)

Metal pollutants produced by industrial wastewaters have become a global concern given their impact on the environment and human health. The purpose of this study was to assess the polyphenols content and the iron chelating activity in the peels of two pomegranate varieties. After the biomass characterization via FT-IR, point of zero charge and surface functional groups analysis, the lead adsorption was then investigated by batch method. Finally, the regeneration of the biomasses was performed by acidic desorption. Polyphenols content of the red peels extract was higher than the yellow one; 102.9±0.9 and 85.9±1.3 mg GAE/g of dry weight, respectively with a half iron chelation inhibitory concentration (IC 50 ) of 227.2±1.7 and 235.9±3.2 µg. mL -1 of extract, successively. For the adsorption isotherms of lead onto the red and yellow pomegranate peels, the Langmuir model was more fitting with an adsorption capacity (Q max ) of 90 and 89.25 mg.g -1 , respectively. The kinetic data corresponded better to the pseudo-second order model. The acidic desorption of lead was successful with a high percentage of recovery. The results demonstrate the effectiveness of these biomasses as biosorbents for lead removal from aqueous solutions with the possibility of their reuse.
Increased future liver function after modified associating liver partition and portal vein ligation/embolization for staged hepatectomy

Background The increasing ratio of functional future liver remnant (functional %FLR) after modified associating liver partition and portal vein ligation/embolization for staged hepatectomy (modified-ALPPS) compared with portal vein embolization (PVE) has not been comprehensively evaluated. Purpose To compare the increasing ratio of functional %FLR between modified-ALPPS and PVE via technetium-99 m-galactosyl human serum albumin single-photon emission computed tomography (99mTc-GSA SPECT/CT) fusion imaging. Material and Methods Seven and six patients underwent modified-ALPPS (modified-ALPPS group) and PVE (PVE group) from 2015 to 2019. The functional %FLR on 99 mTc-GSA SPECT/CT fusion imaging was assessed before and 1 week (modified-ALPPS group) and 3 weeks (PVE group) after each procedure. The increasing ratio of functional %FLR (functional %FLR ratio) was calculated and compared between the two groups. Moreover, the hypertrophy ratio of future liver remnant volume (FLRV ratio) and atrophy ratio of embolized liver volume (.ELV ratio) were evaluated. Results The mean functional %FLR ratios of the modified-ALPPS group (1.47 ± 0.15) and the PVE group (1.49 ± 0.20) were comparable (p > .05). The median FLRV ratio of modified-ALPPS group (1.48) was higher than that of the PVE group (1.16), the median ELV ratio of the PVE group (0.81) was lower than that of the modified-ALPPS group (0.94), and the results significantly differed between the two groups (p < .05). Conclusion The increasing ratio of functional %FLR was comparable between modified-ALPPS and PVE. Compared with PVE, ALPPS was associated with a higher hypertrophy rate of the remnant liver but a lower atrophy rate of the embolized liver.
The Influence of the Thickness of the Materials for the Provisionalization in Minimally Invasive Restorations

This in vitro study aimed to determine the flexural strength and modulus of elasticity of two bisacrylic resins for temporary crowns at different thicknesses, i.e., Structur 3 and Structur Premium, and to compare them with each other. Sixty samples were prepared, thirty of each material, which were made at different thicknesses (1 mm, 1.5 mm, and 2 mm). The dimensions followed the UNE-EN ISO 178:2019 standard, with a length of 24 mm, a width of 10 mm, and the thicknesses described. Materials were subjected to a three-point bending test. For the modulus of elasticity, statistically significant differences were observed between the 1.5 mm and 2 mm thicknesses of Structur 3 material. For Structur Premium, statistically significant differences were observed between the thicknesses 1 mm and 1.5 mm as well as between 1 mm and 2 mm thickness. With respect to flexural strength, no statistically significant differences were observed for either material at the different thicknesses. Significant differences were observed between the materials for both flexural strength and modulus of elasticity, being higher for Structur Premium: Structur Premium has a higher flexural strength and modulus of elasticity than Structur 3. There are significant differences for the modulus of elasticity but not for the flexural strength between thicknesses.
THE CLUSTER POPULATION OF THE IRREGULAR GALAXY NGC 4449 AS SEEN BY THE HUBBLE ADVANCED CAMERA FOR SURVEYS

We present a study of the star cluster population in the starburst irregular galaxy NGC 4449 based on B, V, I, and Hα images taken with the Advanced Camera for Surveys on the Hubble Space Telescope. We derive cluster properties such as size, ellipticity, and total magnitude. Cluster ages and masses are derived fitting the observed spectral energy distributions with different population synthesis models. Our analysis is strongly affected by the age–metallicity degeneracy; however, if we assume a metallicity of ∼1/4 solar, as derived from spectroscopy of H ii regions, we find that the clusters have ages distributed quite continuously over a Hubble time, and they have masses from ∼103 M☉ up to ∼2 × 106 M☉, assuming a Salpeter initial mass function down to 0.1 M☉. Young clusters are preferentially located in regions of young star formation (SF), while old clusters are distributed over the whole NGC 4449 field of view, like the old stars (although we note that some old clusters follow linear structures, possibly a reflection of past satellite accretion). The high SF activity in NGC 4449 is confirmed by its specific frequency of young massive clusters, higher than the average value found in nearby spirals and in the Large Magellanic Cloud (but lower than in other starburst dwarfs such as NGC 1705 and NGC 1569), and by the flat slope of the cluster luminosity function (dN(LV)∝L−1.5VdL for clusters younger than 1 Gyr). We use the upper envelope of the cluster log(mass) versus log(age) distribution to quantify cluster disruption, and do not find evidence for the high (90%) long-term infant mortality found by some studies. For the red clusters, we find correlations between size, ellipticity, luminosity, and mass: brighter and more massive clusters tend to be more compact, and brighter clusters also tend to be more elliptical.
English Education Master’s Program Students’ Perceptions on the Use of Code-Switching in EFL Classroom Context

This paper investigated some factors influencing the use of code-switching in foreign/second language learning processes. Code-switching is related to the shift between the first and second languages done by the speakers in conversational contexts. Based on the theories of code-switching, second language learners frequently apply their first language when communicating with others in order to deliver the messages clearly, maintain group solidarity, and avoid unintended misunderstandings. Data were collected through a classroom survey and interviews with 12 English Education Master’s Program students of Sanata Dharma University, Yogyakarta. Qualitative content analysis was applied to obtain clearer interpretations. The results showed the lecturers and students utilized code-switching more sensibly in the second language classroom context. Further, code-switching will be better to be implemented in informal social interactions rather than foreign/second language classroom settings since it will hamper EFL learners’ success in attaining more fruitful target language competencies.
Further two alien species for the Sicilian waters: Aplus assimilis (Reeve,1846) and Mitrella psilla (Duclos, 1846) (Gastropoda Neogastropoda)

The finding of two further non indigenous species for the Eastern Sicilian rocky coast is here reported. The neo-gastropods Aplus assimilis (Reeve, 1846) and Mitrella psilla (Duclos, 1846) were found living inside the arbor of Catania. Specimens regularly collected during these last five years demonstrate the stability of the populations of both the species inside the harbor, while no other materials emerged from the exam of samples collected around the finding lo-cality. The presence of both the species along Italian coasts was previously ascertained in few scattered localities, while the current represents the first report for Sicily. A human-mediated diffusion is here supposed as for other species found in the island. This last finding brings back to the top the problem of the numerous alien species arrivals during these latest years in Sicily and, more generally, in the Mediterranean Sea.
