Establishment of a Bama miniature pig burn model with different burn depths

Background The skin morphological characteristics of the Bama miniature pig are very similar to those of humans; thus, the Bama miniature pig is an ideal choice for establishing a skin burn model. Methods In this study, 6 ordinary, male, Bama miniature pigs (weight: 23–28 kg and length: 71–75 cm) were used to establish burn models. A mixture of 1 mg of Ketamine and Sumianxin II was used for Bama miniature pigs anesthetizing, and 1 mg of Pentobarbital sodium was added as necessary. The different burn depths were made using a continuous pressure of 1 kg and contact times of 0 s, 10 s, 15 s, 20 s, 25 s, 30 s, 35 s, 40 s, and 45 s by the newly invented electronic burn instrument. The burned tissues were collected and examined with hematoxylin and eosin (H&E) and Masson staining. Results Burning for 10–15 s caused a first-degree burn; the blood vessels in the superficial dermis were dilated and congested, and necrosis occurred above the basal layer of the epidermis. Burning for 20–25 s caused a superficial partial-thickness burn; the whole epidermal layer was necrotic, and the collagen fibers were slightly deformed. Burning for 30–35 s caused a deep partial-thickness burn; the whole epidermal layer and dermal layers were necrotic with leukocyte infiltration zones, and the collagen fibers were disordered, degenerated, and necrotized. Burning for 40–45 s caused a third-degree burn; the skin layers and adipose tissues were necrotic, and the thick blood vessels in the skin adipose tissues were full of disintegrated and agglutinated red blood cells. Conclusions Stable burn depth models of Bama miniature pigs were constructed using a new and innovative electronic burn instrument. Our findings provide a basis for further research on the burn mechanism and evaluations of therapeutic drugs.
Child audiences in South Africa

The consumption of media – especially radio and television – by children has been a topic ofresearch for decades now. Although extensive research has been published on the effects of themedia, also in South Africa, very few (if any) publications address the issue of when and whatchildren are viewing in South Africa, and if something should be done about this behaviour. In thisarticle, specific examples of the viewing patterns of children between the ages of 7 and 15 arepresented in the context of unacceptable material to which they are exposed. The different rolesof parents, broadcasters and legislators are discussed, against the backdrop of recent literature,in an attempt to suggest a way forward.
QUASAR OUTFLOW CONTRIBUTION TO AGN FEEDBACK: OBSERVATIONS OF QSO SDSS J0838+2955

We present a detailed analysis of the Astrophysical Research Consortium 3.5 m telescope spectrum of QSO SDSS J0838+2955. The object shows three broad absorption line (BAL) systems at 22,000, 13,000, and 4900 km s−1 blueshifted from the systemic redshift of z = 2.043. Of particular interest is the lowest velocity system that displays absorption from low-ionization species such as Mg ii, Al ii, Si ii, Si ii*, Fe ii, and Fe ii*. Accurate column densities were measured for all transitions in this lowest velocity BAL using an inhomogeneous absorber model. The ratio of column densities of Si ii* and Fe ii* with respect to their ground states gave an electron number density of log ne (cm−3) = 3.75 ± 0.22 for the outflow. Photoionization modeling with careful regards to chemical abundances and the incident spectral energy distribution predicts an ionization parameter of log UH = −1.93 ± 0.21 and a hydrogen column density of log NH (cm−2) = 20.80 ± 0.28. This places the outflow at 3.3+1.5−1.0 kpc from the central active galactic nucleus (AGN). Assuming that the fraction of solid angle subtended by the outflow is 0.2, these values yield a kinetic luminosity of (4.5+3.1−1.8) × 1045 erg s−1, which is (1.4+1.1−0.6)% the bolometric luminosity of the QSO itself. Such large kinetic luminosity suggests that QSO outflows are a major contributor to AGN feedback mechanisms.
Nitrogen remobilization and its importance in nitrogen use efficiency (NUE) of crops

Nitrogen (N) remobilization during grain filling from pre-anthesis N uptake and stored in different tissues of crop N use efficiency (NUE). N is remobilized from to sink (young leaves or grains) with the help of nitrate/amino acid transporters. Nearly 80% of grain N in cereals is derived from N remobilized from vegetative tissues. Remobilization of N within the plant takes place from older leaves to young leaves, leaves to grains, senescing organs to grains, from storage parts to grains. Enzymes involved in N remobilization include glutamine synthetase (GS), glutamate dehydrogenase (GDH), asparagine synthetase (AS) and proteases. Among them, cytosolic GS plays a key role during N remobilization in cereals. There are various senescence-associated genes (SAG) involved in N remobilization from older degrading leaves to younger leaves and grains. Autophagy (ATG) is an important mechanism involved in the degradation of stored N in the form of various proteins to amino acids, which are transported to long-distance in the form of glutamine and asparagine via phloem tissue. There is a complex network of genes, mechanisms, and factors associated with N remobilization, which needs to be considered for improving NUE of crops.
Kerr–de Sitter and Kerr–anti–de Sitter black holes as accelerators for spinning particles

It is shown that the Kerr black hole could act as accelerators for spinning particles. In principle, it could obtain arbitrarily high energy for extremal Kerr black hole. In this paper, we extend the previous research to the Kerr-(anti-)de Sitter background and find that the cosmological constant plays an important role in the result. For the case of Kerr-anti-de Sitter black holes, like the Kerr background, only the extremal Kerr-anti-de Sitter black holes can have a divergent center-of-mass energy of collision. While, for the case of Kerr-de Sitter black holes, the collision of two spinning particles can take place on the outer horizon of the black holes and the center-of-mass energy of collision can blow up if one of the collision particle takes the critical angular momentum. Hence, non-extremal Kerr-de Sitter black holes could also act as accelerators with arbitrarily high center-of-mass energy for spinning particles.
THE AXIS RATIO DISTRIBUTION OF X-RAY CLUSTERS OBSERVED BY XMM-NEWTON

We derive the axis ratio distribution of X-ray clusters using the XMM-Newton catalog. By fitting the contour lines of the X-ray image by ellipses, we confirm that the X-ray distribution is well approximated by the elliptic distribution with a constant axis ratio and direction. We construct a simple model describing the axis ratio of the X-ray gas assuming the hydrostatic equilibrium embedded in the triaxial dark matter halo model proposed by Jing & Suto and the hydrostatic equilibrium. We find that the observed probability density function of the axis ratio is consistent with this model prediction.
Patient-Centered Care and Healthcare Consumerism in Online Healthcare Service Advertisements: A Positioning Analysis

Patient-centered care and healthcare consumerism are the two most dominant ideas about the relationship between patients and providers in the United States. To identify providers’ positions between the two perspectives, we analyzed the content of direct-to-consumer healthcare service advertisements. The advertisements were collected in the state of Nevada (N = 323) and their landing pages were analyzed for provider attributes, patient experience features, and terms referring to patients and providers. The results showed that the advertisements fully embraced the notion of patient-centeredness by commonly claiming patient-centered care and frequently using the term “patient. ” The advertisements also contained multiple indicators of healthcare consumerism, although they avoided using the terms “consumer/customer/client” closely associated with consumerism. Contrary to the prominence of patient experience features, provider attributes were not common. An additional analysis of inter-specialty differences in advertising features confirmed the strong consumerism position of cosmetic surgery providers. Application of the healthcare service advertising analytic scheme developed for this study could help providers and healthcare administrators recognize how their advertising messages may reflect their values.
Mood Analysis during the COVID-19 Pandemic in Brazil through Music

In this paper, we investigate the oscillation in the general feelings of the Brazilian population during the Pandemic through the songs consumed. We analyze Brazilian streaming musical consumption between 2019 and 2021. In special, we focus on special dates that have changed history, such as the beginning of the pandemic in the country, the dates of increase in cases, milestone dates in deaths, the beginning of vaccination, among others. Data was collected through Spotify API and made publicly available. Our results show people have preferred more danceable and positive songs during the period analyzed.
The Apparent Velocity and Acceleration of Relativistically Moving Objects

Although special relativity limits the actual velocity of a particle to $c$, the velocity of light, the observed velocity need not be the same as the actual velocity as the observer is only aware of the position of a particle at the time in the past when it emits the detected signal. We consider the apparent speed and acceleration of a particle in two cases, one when the particle is moving with a constant speed and the other when it is moving with a constant acceleration. One curious feature of our results is that in both cases, if the actual velocity of the particle approaches $c$, then the apparent velocity approaches infinity when it is moving toward the observer and $c/2$ when it is moving away from the observer.
The role of edge-driven convection in the generation ofvolcanism – Part 2: Interaction with mantle plumes, applied to the Canary Islands

Abstract. In the eastern Atlantic Ocean, several volcanic archipelagos are located close to the margin of the African continent. This configuration has inspired previous studies to suggest an important role of edge-driven convection (EDC) in the generation of intraplate magmatism. In a companion paper (Manjón-Cabeza Córdoba and Ballmer, 2021), we showed that EDC alone is insufficient to sustain magmatism of the magnitude required to match the volume of these islands. However, we also found that EDC readily develops near a step of lithospheric thickness, such as the oceanic–continental transition (“edge”) along the western African cratonic margin. In this work, we carry out 3D numerical models of mantle flow and melting to explore the possible interactions between EDC and mantle plumes. We find that the stem of a plume that rises close to a lithospheric edge is significantly deflected ocean-ward (i.e., away from the edge). The pancake of ponding hot material at the base of the lithosphere is also deflected by the EDC convection cell (either away or towards the edge). The amount of magmatism and plume deflection depends on the initial geometric configuration, i.e., the distance of the plume from the edge. Plume buoyancy flux and temperature also control the amount of magmatism, and influence the style and extent of plume–EDC interaction. Finally, comparison of model predictions with observations reveals that the Canary plume may be significantly affected and deflected by EDC, accounting for widespread and coeval volcanic activity. Our work shows that many of the peculiar characteristics of eastern Atlantic volcanism are compatible with mantle plume theory once the effects of EDC on plume flow are considered.
The distinguishing factor for gravity models: stellar population synthesis

Alternative gravitations of Milgrom (MOND), Moffat (MOG), and CDM scenarios all simulate rotation curves of spirals with reasonable details. They display significant disparities however in predicting the stellar mass-to-light (M∗/L) ratios of the galaxies. We maintain this feature could serve as a distinguishing factor between different alternative theories. We analyze the rotation curves of 46 low- and high-surface brightness galaxies and compare the resulting M∗/Ls with the predictions of the Stellar Population Synthesis (SPS) scheme. The color‐M∗/L correlation obtained for MOND is consistent with predictions of SPS models. MOG does not show this consistency, and the M∗/Ls of CDM model shows large dispersions. Furthermore, M∗/L ratios of MOND with Bekenstein interpolating function favor Kroupa’s initial mass function (IMF) of the SPS scheme, while those of MOND with standard and simple interpolating functions are consistent with Salpeter’s IMF. Here is another indication to differentiate between different IMFs that are used in SPS context.
Quantitative Measurement of the Pressure and Shear Stress Acting on the Body of a Wheelchair User Using a Wearable Sheet-Type Sensor: A Preliminary Study

To provide a safer sitting environment for wheelchair users, it is important to quantitatively measure the forces acting on the contact surface between the seat and the person in the wheelchair. In addition to the pressure acting on the buttocks, shear forces have received particular attention in recent years; however, measuring shear force is more difficult than measuring pressure. To obtain this measurement, a thin and flexible sensor that can be used in a natural state on a wheelchair is needed. Therefore, we constructed a measurement system using our previously developed wearable sheet-type sensor (0.9 mm thick). In this study, preliminary tests were conducted using human dummies before testing on humans. Sensors were placed in four locations on the humanoid dummy’s back and buttocks, and the electric wheelchair was tilted and reclined five times each. The results showed that the sensor output pattern was reproducible and valid enough to proceed to the next step. However, the shear force in the internal and external directions was greater than expected, which indicates that the equipment and testing methods must be reviewed. On the basis of the results obtained in this preliminary study, preparations will be made for testing on human subjects.
Radio Emission from Pulsar Wind Nebulae without Surrounding Supernova Ejecta: Application to FRB 121102

In this paper, we propose a new scenario in which a rapidly rotating strongly magnetized pulsar without any surrounding supernova ejecta repeatedly produces fast radio bursts (FRBs) via a range of possible mechanisms; simultaneously, an ultra-relativistic electron/positron pair wind from the pulsar sweeps up its ambient dense interstellar medium, giving rise to a non-relativistic pulsar wind nebula (PWN). We show that the synchrotron radio emission from such a PWN is bright enough to account for the recently discovered persistent radio source associated with the repeating FRB 121102 within reasonable ranges of the model parameters. Our PWN scenario is consistent with the non-evolution of the dispersion measure inferred from all of the repeating bursts observed in four years.
The Antimicrobial Peptide LJ-hep2 from Lateolabrax japonicus Exerting Activities against Multiple Pathogenic Bacteria and Immune Protection In Vivo

Hepcidin is widely present in many kinds of fish and is an important innate immune factor. A variety of HAMP2-type hepcidins have strong antimicrobial activity and immunomodulatory functions and are expected to be developed as substitutes for antibiotics. In this study, the antimicrobial activity of Hepc2 from Japanese seabass (Lateolabrax japonicus) (designated as LJ-hep2) was investigated using its recombinant precursor protein (rLJ-hep2) expressed in Pichia pastoris and a chemically synthesized mature peptide (LJ-hep2(66–86)). The results showed that both rLJ-hep2 and synthetic LJ-hep2(66–86) displayed broad antimicrobial spectrum with potent activity against gram-negative and gram-positive bacteria, and fungi. Especially, LJ-hep2(66–86) had stronger antimicrobial activity and exhibited potent activity against several clinically isolated multidrug-resistant bacteria, including Acinetobacter baumannii, Escherichia coli, Pseudomonas aeruginosa, Klebsiella pneumoniae and Enterococcus faecium. Moreover, LJ-hep2(66–86) exerted rapid bactericidal kinetic (killed tested bacteria within 2 h), induced significant morphological changes and promoted agglutination of E. coli, P. aeruginosa and Aeromonas hydrophila. The activity of LJ-hep2(66–86) against E. coli, P. aeruginosa and A. hydrophila was stable and remained active when heated for 30 min. In addition, LJ-hep2(66–86) exhibited no cytotoxicity to the mammalian cell line HEK293T and fish cell lines (EPC and ZF4). In vivo study showed that LJ-hep2(66–86) could improve the survival rate of marine medaka (Oryzias melastigma) by about 40% under the challenge of A. hydrophila, indicating its immunoprotective function. Taken together, both rLJ-hep2 and LJ-hep2(66–86) have good prospects to be used as potential antimicrobial agents in aquaculture and medicine in the future.

The most common being anxiety, followed by depression and stress. In severity grading moderate was common. It shows the need for early interven�on and management. Abstract METHODOLOGY A web-based cross-sec�onal study among FJRD was done to using Depression, Anxiety, and Stress Scale (DASS-21).
The Robustness of Phase Mapping as a Non-Gaussianity Test

The identification and extraction of non-Gaussian signals are two of the main cosmological challenges facing future experimental measurements of the cosmic microwave background temperature pattern. In this Letter we present a detailed account and test the robustness of a generalized statistical measure based on a novel method of representation of Fourier phases using the return map. We demonstrate the usefulness (and limitations) of this method by testing it on controlled simulated maps, which show that it is both robust and powerful, particularly in detecting non-Gaussianity from systematics.
Form Invariance and Symmetry in the Neutrino Mass Matrix

We present the general form of the unitary matrices keeping invariant the Majorana neutrino mass matrix of specific texture suitable for explaining oscillation data. In the case of the Tri-bimaximal pattern with two degenerate masses we give a specific realization of the underlying U(1) symmetry which can be uplifted to a symmetry in a complete theory including charged leptons. For this, we present a model with three light SM-like Higgs doublets and one heavy Higgs triplet and find that one can accommodate the hierarchy of the charged lepton masses. The lepton mass spectrum can also be achieved in another model extending the SM with three SM-singlet scalars transforming non trivially under the flavor symmetry. We discuss how such a model has room for generating enough baryon asymmetry through leptogenesis in the framework of Type-I and II seesaw mechanisms.

X-ray spectrophotometric remote sensing of diffuse auroral ionization. Technical report

Auroral electron precipitation produces both E-region ionization and bremsstrahlung x rays. In a set of coordinated observations these atmospheric effects of electron precipitation were measured simultaneously by the x-ray sensor on the DMSP/F2 spacecraft and by the incoherent-scatter radar at Chatanika, Alaska. In all data sets there was good agreement between the locations of the x-ray source regions and the regions of enhanced E-region ionization. Detailed comparisons were made between the measured and derived altitude profiles of ionization for two auroral conditions, a pre-midnight auroral band and a sunlit diffuse aurora. These comparisons validate the ability to derive auroral ionization from satellite-based x-ray measurements.
Market Timing Signals with High-Frequency Finance Data for Practitioners Based on RRV Model and Momentum Effect

—Based on high frequency data, we establish a method to measure the market risk using realized volatility, and study the momentum effect of intraday stock market. In the first part we establish relative realized volatility model to help investors better model and forecast volatility of the stock price by capturing large deviations from the average realized volatility level using the second-level financial data of Russell 1000 Large-Cap Stocks ETF. Next, we divide the trading data of DIA index for nearly 20 years in minute-level into non-crisis period, 2008 financial crisis period and the recent COVID-19 epidemic period. The effect of stock market momentum effect in these special periods is investigated, and the impact of COVID-19 on the stock market is analyzed in detail based on such effect. The results show that the intraday momentum effect will be more obvious in the economic crisis caused by financial system factors similar to the 2008 financial crisis, and in severe public event crises like COVID-19, the effect may reverse due to the digestion of market information and the influence of investor sentiment, but it will still maintain the normal positive momentum effect for part of the time.
