HST/STIS Echelle Spectra of the dM1e Star AU Microscopii Outside of Flares

We report on observations of the dM1e flare star AU Microscopii obtained with the Space Telescope Imaging Spectrograph (STIS) on 1998 September 6. A total of 10,105 s of observations were obtained with the medium-resolution E140M grating. We report here on the 9200 s of "quiescent" data when the star did not obviously flare. In this data set, we identify 142 emission lines from 28 species, including low-temperature chromospheric lines (e.g., C I, O I), transition-region lines (e.g., C II-IV, N IV, O III-V, Si II-IV), and the coronal line Fe XXI 1354 Å. There are a number of intersystem lines that are useful for measuring electron densities. We discuss line redshifts and the broad wings of transition-region lines that provide evidence of microflare heating. We derive the emission-measure distribution and compare it with the solar one. We also discuss the shape and formation mechanisms of the He II 1640 Å lines. The analysis of the flare data and of the interstellar absorption features seen in the H I, D I, C II, and O I resonance lines will be published elsewhere.
The Influence of Average Snow Depth on Monthly Mean Temperature Anomaly

Abstract Linear regression equations relating monthly mean temperature anomaly to average monthly snow depth and its anomaly were derived for 15 selected stations, using 8 yr of data. It was found that, depending on the characteristics of the station location, from about 10 to 55 percent of the variance of the monthly mean temperature anomaly could be explained in terms of the average monthly snow depth or its anomaly.
Awareness and Perceptions of Climate Variability Adaptation among Forest-adjacent Communities in Mau Forest, Kenya

Adequate knowledge of climate variability is essential for the success of any adaptation or mitigation efforts. Thus, a study was conducted to investigate the levels of awareness and perceptions on the adaptation of climate variability among forest-adjacent communities (FACs) in Mau Forest, Kenya. Data for the investigation was generated through the administration of 313 questionnaires across randomly selected forest-adjacent households. Of the entire questionnaire, 311 were analysed, while two were returned uncompleted and therefore discarded. Descriptive and inferential statistical analyses were conducted. Descriptive analysis showed that 96% of the respondents had knowledge of climate variability, while 4% claimed no knowledge of it. Nearly two-thirds of respondents (65%) reported that they receive weather information, with media (electronic and print) cited as the most common (63%) source of this information. As regards frequency of information, those respondents who get information about climate variability occasionally constituted 60%, while 29% of respondents received information frequently. However, 14% of respondents rarely received any climate-related information. Respondents who received climate-related information occasionally (sometimes) constituted 56%. Alternatively, respondents reported that they obtained weather information from agricultural extension officers (17.6%) and Kenya Forestry Service (KFS) officials (15.3%). The perceptions of the farmers that they had observed erratic weather patterns with a general decline in rainfall and an increase in temperatures were corroborated by scientific data as a trend analysis on rainfall and temperature data over a 20-year period mirrored the farmer’s perceptions. A logistic regression model was fitted to determine the socioeconomic factors that influence farmers’ choice of adaptation to climate variability. The ANOVA test results (F-test) show that overall, the logistic regression model was significant (df = 310, p = 0.002). Results of the model revealed that household head age (df = 310, p = 0.015), household head years of residency (df = 310, p = 0.034), and farming experience (df = 310, p = 0.024) were all significant factors that influence FACs’ decision to adopt to climate variability either positively or negatively. This study therefore recommends for more awareness creation and training of FACs of East Mau on how to identify and deal with changing climatic conditions.
Application of Resistivity and Seismic Refraction Tomography for Landslide Stability Assessment in Vallcebre, Spanish Pyrenees

Geophysical surveys are a noninvasive reliable tool to improve geological models without requiring extensive in situ borehole campaigns. The usage of seismic refraction tomography (SRT), electrical resistivity tomography (ERT) and borehole data for calibrating is very appropriate to define landslide body geometries; however, it is still only used occasionally. We present here the case of a Spanish Pyrenees slow-moving landslide, where ERT, SRT and lithological log data were integrated to obtain a geological three-dimensional model. The high contrasts of P-wave velocity and electrical resistivity values of the upper materials (colluvial debris and clayey siltstone) provided accurate information on the geometry of the materials involved in the landslide body, as well as the sliding surface. Geophysical prospecting allowed us to identify the critical sliding surface over a large area and at a reduced cost and, therefore, gives the geophysical method an advantage over borehole data. The three-dimensional model was used to carry out stability analyses of a landslide in 2D and 3D, which, coherently with previous studies, reveal that the lower part is more unstable than the upper units.
ANIMA-LIE: Android-Based Learning Media on Animal Life Cycles Materials for Elementary School

The learning media used for teachers in online learning during the pandemic are only limited to using pictures, words, sounds, videos, and powerpoints in the form of simple presentations. Thus, the media is not optimal in helping students understand the material and does not increase students' direct experience. It takes the development of online learning media based on android applications to solve these problems. This study aims to develop an android-based learning media "Anima-lie" on animal life cycle material for grade IV elementary school. The research model used is Research and Development (R&D) by applying the ADDIE development model. This application was piloted on 37 fourth grade students. The instrument used is a validation questionnaire for 2 material experts, 2 media experts, and a user response questionnaire. The results of the product developed based on the assessment of material experts get an average score percentage of 85.5% in the good category and for the media expert assessment the average score percentage is 89.93% in the very good category. For the results of student responses, the percentage of the average score is 83.64% with a good category. Based on the data results indicate that the development of the Android-based mobile learning application "Anima-lie" with animal life cycle material is suitable for use as a learning medium for fourth grade elementary school students.
A Single Center, Prospective, Randomized, Blinded Study to Evaluate the Efficacy and Safety of a Topical Tripeptide/Hexapeptide Anhydrous Gel When Used Pre- and Post- Hybrid Fractional Laser for the Treatment of Acne Scars

Background Acne scarring remains a significant problem. Laser therapy has produced varying results with deeper ablative therapies occasionally associated with side effects including delayed healing, infection, scarring, erythema, acne, milia, edema and dyspigmentation. Objective Can adjuvant topical therapy impact the healing process and outcome of patients treated with fractional laser for acne scarring? Methods and Materials Ten patients were randomized to receive either Regenerating Skin Nectar with TriHex Technology®– RSN or a bland moisturizer. Patients underwent two laser procedures one month apart with Hybrid Fractional Laser. The topical was applied twice daily for 2 weeks prior to the first laser procedure, and through completion of the study. Seven study visits occurred over a 90-day period. Measurements were conducted in lesional and non-lesional areas – transepidermal water loss (TEWL), erythema, photography, Goodman and Baron qualitative scale, Global Aesthetic Improvement Scale and patient questionnaires – to assess functional recovery and aesthetic outcomes in the scarred areas. One patient from each cohort consented to biopsy before the procedures and 90 days after the first procedure. Results Reduced TEWL scores in the RSN group were evident at all time points with statistically significant reductions occurring 4 days after first and second procedures indicating more efficient fluid conservation at a critical point in the healing trajectory. Erythema index demonstrated a consistent decrease in the RSN cohort over the control from day 4 through day 90 on lesional and non-lesional skin. Acne scar assessment scores improved in the RSN cohort compared with the control at all time points. Biopsy results showed early elastin regeneration in the RSN biopsy with controlled non-hypertrophic collagen formation evident. Conclusion The use of RSN pre- and post- laser resurfacing significantly decreased postprocedural TEWL and erythema, and increased aesthetic improvement in acne scars and patient satisfaction, when compared with bland moisturizer.
Fast Detection of Weak Arc Faults Based on Progressive Singular-Value-Decomposition and Empirical Analyses

The aim of this study is to provide a fast and reliable approach to detect weak arc faults that do not noticeably distort the bus current, with the minimum possible arc duration required to respond in low-voltage AC systems. Progressive singular-value decomposition is utilized to filter interference components, primarily AC/DC components. Then, the signals are thoroughly decomposed by empirical analytic tools in the time-frequency domain, combined with the fast Fourier transform to enhance feature extraction in the frequency domain. The features are passed to the neural networks, where the networks are trained and validated repetitively by datasets that are randomly selected from the data sampling. The comparison experiments demonstrate the excellent performance of the proposed method under all crucial evaluation criteria of arc-fault detection.
Knowledge, Attitude, and Acceptance of Sinopharm and AstraZeneca’s COVID-19 Vaccines among Egyptian Population: A Cross-Sectional Study

Background: This study aimed to evaluate the Egyptian population’s preference and awareness related to available COVID-19 vaccines and to determine different factors that can affect beliefs concerning these vaccines. Methods: A cross-sectional web-based study was carried out among the general population in Egypt. Data collection was conducted via an online questionnaire. Results: About 426 subjects participated in the survey. Vaccine preference is nearly equally even (50%) among all respondents. There was no significant difference in vaccine preference according to age, gender, residence, educational level, or social status. About 50% of public respondents mentioned that both AstraZeneca and Sinopharm vaccines do not offer protection against new variant COVID-19 strains. Healthcare workers are the lowest respondents to agree that vaccines offer protection against new COVID-19 variants (10.9%) compared to unemployed respondents (20.3%) and other professions (68.8%) with a statistically significant difference (p < 0.005). Safety of vaccine administration among children below 18 showed statistical differences for gender and educational level predictors. Conclusions: Most of the study population has satisfying knowledge about the COVID-19 vaccine. Continuous awareness campaigns must be carried out so that the people’s background is updated with any new information that would help in raising the trust in vaccination.
SCATTERING OF SHEAR WAVES BY SPHERICAL OBSTACLES

The problem of the scattering of plane S waves by a perfectly rigid, infinitely dense sphere is formulated. Calculations are made for the case in which the medium outside the sphere has a Poisson’s ratio of 14. The range of sizes of obstacles used in the calculations includes radii very small compared with the wave length and radii comparable to the wave length. The scattered wave motions include a P mode and two S modes. One of the S modes has a formal correspondence to the SH mode of plane seismology; the other corresponds to the SV mode. At large distances from the obstacle the scattered P and S fields are computed together with the phase shifts in time occurring in all the components. For small obstacles, the scattered azimuthal S component is circularly symmetric; the scattered meridional S component diffraction pattern is generally elongated in the direction of propagation; the scattered P component is generally broadside to the direction of propagation.
Some counterexamples to the regularity of Monge-Ampère equations

We present examples to show that the solution u of the MongeAmpere equation det(D2u) = f(x), with u = 0 on the boundary, may not lie in W2 ,p or in C1 , t for noncontinuous and positive f(x) and for continuous and nonnegative f(x) . Recently L. A. Caffarelli proved interior W2 P estimates and derivative Holder estimates for viscosity solutions of the Monge-Ampere equation (1) { M(u) = det(D2u) = f(x) in LI, u u=O on aK, where Q is a convex domain in Rn with B1 c Q c Bn and f is bounded and nonnegative. His main results are as follows: Proposition. (1) If f is strictly positive, then u is strictly convex and u E Cl a(Q) for some a> 0. (2) If, moreover, f is continuous, then u e W2 P(B1/2) for any p > 1. (3) If feCa,then UEC2,a. The purpose of this paper is to present some examples to show that in the Proposition above, if f is not continuous, u may fail to be of class W2 p ; if f is not strictly positive, u may fail to be C1 a smooth for any a > 0, even though f(x) is continuous. We discuss weak solutions only. It is indicated by Caffarelli that a weak solution is also a viscosity solution for Monge-Ampere equations and that, for continuous f(x), they are equivalent. Our examples depend on the following simple property of Monge-Ampere equations. Lemma 1. Let Q1 and Qi2 be two domains in Rn with disjoint interiors. Suppose u1 and U2 are convex and verify M(u) = f(x) in QI and 02, respectively. If uI = u2, Du1 = Du2 on a1 n Ina2, then

Positive correlation between organic anion transporter 1B function indicated by plasma concentration of coproporphyrin‐I and blood concentration of cyclosporin A in real‐world patients

Cyclosporin A (CyA) has potent inhibitory activity on organic anion transporting polypeptide 1B (OATP1B), causing drug–drug interactions with its substrate drugs. 3‐carboxy‐4‐methyl‐5‐propyl‐2‐furanpropionate (CMPF), a uraemic toxin, has also been suggested to inhibit OATP1B activity. Recent study has identified coproporphyrin‐I (CP‐I) as a specific endogenous substrate for OATP1B, which is useful to indicate OATP1B activity. We investigated the relationship of CP‐I with CyA and CMPF concentrations in patients taking CyA.
Ritz–Galerkin Methods for Singular Boundary Value Problems

This paper is concerned with the application of the Ritz–Galerkin method to the numerical solution of singular boundary value problems of the type arising when Poisson’s equation on, a domain with cylindrical or spherical symmetry is reduced to a one-dimensional problem. The objective is to derive a priori $L_2 $- and $L_\infty $-norm estimates for the error. The difficulty is that these norms are not natural norms for the reduced problem. With the aid of B-splines we prove some nonstandard approximation-theoretic results and use these to derive the desired error estimates. Some numerical results are presented.
Effects of basic fertilizer ratio and nitrogen topdressing at jointing stage on flour thermal properties of waxy maize

Clarifying the change dynamics of flour thermal properties among different fertilizer treatments could improve the grain quality. In the present study, the effects of basic fertilizer ratio (N, P2O5 and K2O 75 kg/ha single or mix applied) and N topdressing at jointing stage (0, 150 and 300 kg/ha) on the thermal properties of waxy maize flour were studied using Suyunuo5 and Yunuo7 as materials in 2011–13. The results indicated that the flour thermal characteristics were affected by single or interactions of planting year, variety, basic fertilizer ratio and N topdressing. Among different basic fertilizer ratio treatments, gelatinization temperatures were highest at N 75 kg/ha+P2O5 75 kg/ha+K2O 75 kg/ha treatment and lowest at N 75 kg/ha treatment. Gelatinization enthalpy (ΔHgel) was increased by basic fertilizer. Compared with blank, application of N 75 kg/ha+ K2O 75 kg/ha or P2O5 75 kg/ha had no effect on retrogradation enthalpy and retrogradation percentage (%R), and those two parameters decreased by other basic fertilizer treatments. Among different N topdressing treatments, higher gelatinization characteristics were present at N topdressing 150 kg/ha treatment and %R was gradually increased with N rate increase. The plants grown in 2012 had higher rainfall and low sunlight presented higher %R and lower ΔHgel, and plants grown in warm condition had higher gelatinization temperature. The results of correlation and principal component analysis indicated that the main estimation parameters on thermal properties were gelatinization temperature, followed by %R and ΔHgel.
Dominant Regimes of the Ross Ice Shelf Surface Wind Field during Austral Autumn 2005

Abstract An analysis of the surface wind field across the Ross Ice Shelf, Antarctica, is conducted for austral autumn 2005. The airflow is divided into dominant wind regimes identifying similar wind patterns and the associated typical atmospheric forcing. The results of previous research and a seasonal analysis of the recently expanded network of automatic weather stations in the Ross Ice Shelf region are used to define the dominant wind regimes. Events composing each wind regime are identified by matching wind speed and wind direction observations at several automatic weather station sites for durations of at least 10 h. The four different dominant wind regimes are barrier wind, strong katabatic, weak katabatic, and light wind. Each wind regime is studied through the use of wind rose plots and sea level pressure fields from the Antarctic Mesoscale Prediction System. The sea level pressure fields are used to characterize the forcing of the surface wind field by synoptic pressure gradients. The four domina.
