ObjectivesUnderweight remains the primary public health concern among under-five-year-old children in Ethiopia, despite numerous government-implemented nutrition-specific and sensitive interventions. Therefore, this study aimed to assess underweight and associated factors among children in South Ethiopia.MethodsBetween March and April 2021, 717 children in the South Ari district who were between the ages of 6 and 59 months participated in a cross-sectional study. To choose a sample of households containing a minimum of one child between the ages of 6 and 59 months, a multi-stage sampling procedure was used. Data were collected by interviewer-administered structured questionnaires from the mothers of the children. To determine the factors associated with being underweight, a binary logistic regression analysis was built. All variables with a p-value &lt;0.25 in the bivariable analysis were entered into a multivariable logistic regression analysis. To assess the strength of the association, an adjusted odds ratio (AOR) with a 95% confidence interval was used. With a p-value below 0.05, statistical significance was declared.ResultsThe prevalence of underweight was determined to be 29.7% (95% CI: 26.5%, 33.2%). Child age 6–23 months [adjusted odds ratio (AOR) = 0.28; 95% confidence interval (CI): 0.18, 0.44], food insecurity (AOR = 1.48; 95% CI: 1.04, 2.10), sub-optimal child dietary diversity (AOR = 1.44; 95% CI: 1.01, 2.03), birth interval &lt;24 months (AOR = 2.49; 95% CI: 1.75, 3.54), and common childhood illness (AOR = 2.21; 95% CI: 1.52, 3.21) were associated with being underweight.ConclusionUnderweight among children is predicted by household food insecurity, suboptimal dietary diversity, and common childhood illnesses, necessitating further efforts to improve food security and manage common illnesses.

Abstract
The characteristic of inverted singlet-triplet excited states, in which the lowest singlet excited state (S1) is lower than the lowest triplet state (T1) in energy, was observed in a dialkylamine-substituted pentaazaphenalene derivative, 5AP-N(C12)2. The transient photoluminescence measurements showed that the reverse intersystem crossing has virtually zero activation energy, whereas the intersystem crossing is proceeded by a thermal activation process. T1 was located energetically above S1 with a negative energy gap between S1 and T1 (ΔE
ST) of −37 meV. Fluorescence and phosphorescence spectra also confirmed the negative ΔE
ST of −46 to −32 meV.

Suppose G is a graph with vertices p dan edges q. Super graceful labeling is a one-to-one function maping on f:V(G) È E(G)  {1,2, … , p + q} such that f(uv) = ½f(u) – f(v)½ differs for each edge uv Î E(G). A graph G is called super graceful if it can be labeled according to the definition of super graceful labeling. The graph B(m,n,k) is a graph consisteing of a path graph of length k conneting the star graph K(1,m) and K(1,n) at the pendant ends. Meanwhile, the graph Pn(1,2,…,n) is a path graph of length by n combining each vertex on the path graph with edges i to i members (1,2,…,n). In this journal, it will be shown that graph B(m,n,k) and graph Pn(1,2,…,n) are super graceful graphs.
Perilaku Curang Para Pejabat di Pengadilan: Sebuah Analisis Naratif terhadap Teks Amos 5:7-13

Published: May 2024

Artikel ini bertujuan untuk menganalisis tindak kecurangan yang terjadi di pintu gerbang, tempat berlangsungnya proses peradilan pada masa itu menurut teks Amos 5:7-13. Melalui metode kualitatif, yang difokuskan ke analisis naratif, akan diulas secara deskriptif empat macam perilaku koruptif para pejabat. Pertama, mereka tidak mengganggap serius peran dan tanggung jawab mereka sebagai penegak keadilan di pintu gerbang (ay.7-9). Amos menyebut mereka sebagai orang yang menjadikan keadilan seperti ipuh, tanaman beracun yang tak berguna. Mereka menghempaskan kebenaran ke tanah. Kedua, mereka alergi terhadap kritikan (ay. 10). Mereka menutup telinga terhadap pelbagai protes yang dilayangkan. Ketiga, mereka menyalahgunakan kekuasaan untuk memeras yang lemah (ay.11). Tidak ada rasa simpati dalam diri mereka terhadap yang berkesusahan. Keempat, mereka menyukai suap (ay. 12). Mereka memperkaya diri dengan membela yang sanggup bayar di pengadilan. Dampak dari perilaku curang ini adalah bahwa orang miskin tidak mendapatkan keadilan dan perlindungan yang semestinya. Melalui kritiknya, Amos menegaskan kepada setiap orang, khususnya para pemangku jabatan, untuk segera bertobat. Pertobatan yang dimaksud adalah menghentikan segala bentuk malapraktik. Mereka yang mempunyai kedudukan wajib menjalankan tugas dan tanggungjawab mereka dengan semestinya. Mereka harus menegakkan keadilan tanpa pandang bulu.
Kooperatives Modell zur Ermittlung der vergütungswürdigen abweichenden Bauzeit im maschinellen Tunnelvortrieb/Cooperative model for determining the compensable deviating construction time in mechanised tunnelling
Authors: Bisenberger Tobias , Urban Harald , Schranz Christian 
Published: May 2024

Der Tunnelbau ist eine jener Disziplinen, die in der Planungsphase äußerst stark von Annahmen abhängt, die dann in der Bauphase von stärkeren Abweichungen betroffen ist. Diese Abweichungen können zu größeren Verzögerungen im Bauablauf führen, und somit auch zu höheren Kosten. Dies führt unweigerlich zu Streitigkeiten, wer diese Kosten zu tragen hat. Daher ist es sinnvoll, sich vor Baubeginn Gedanken über die Zuteilung von Kostenverantwortlichkeiten bei Verzögerungen zu machen.

Hier setzt dieser Artikel an und stellt ein im Zuge einer Dissertation entwickeltes Modell vor, das in einem kooperativen Prozess die vergütungswürdige abweichende Bauzeit für den maschinellen Tunnelvortrieb beschreibt. Dieser Artikel zeigt die verschiedenen Bestandteile des Modells sowie deren Zusammenhänge. Mit diesem Modell lassen sich die Risikosphären vor dem Bau festlegen und die vergütungswürdige Bauzeitabweichungen während der Bauphase automatisch aufgrund gemeinsam zuvor festgelegter Parameter bestimmen.
Pupil dilation reflects effortful action invigoration in overcoming aversive Pavlovian biases
Authors: Algermissen Johannes , den Ouden Hanneke E. M. 
Published: May 2024

Abstract“Pavlovian” or “motivational” biases describe the phenomenon that the valence of prospective outcomes modulates action invigoration: Reward prospect invigorates action, whereas punishment prospect suppresses it. The adaptive role of these biases in decision-making is still unclear. One idea is that they constitute a fast-and-frugal decision strategy in situations characterized by high arousal, e.g., in presence of a predator, which demand a quick response. In this pre-registered study (N = 35), we tested whether such a situation—induced via subliminally presented angry versus neutral faces—leads to increased reliance on Pavlovian biases. We measured trial-by-trial arousal by tracking pupil diameter while participants performed an orthogonalized Motivational Go/NoGo Task. Pavlovian biases were present in responses, reaction times, and even gaze, with lower gaze dispersion under aversive cues reflecting “freezing of gaze.” The subliminally presented faces did not affect responses, reaction times, or pupil diameter, suggesting that the arousal manipulation was ineffective. However, pupil dilations reflected facets of bias suppression, specifically the physical (but not cognitive) effort needed to overcome aversive inhibition: Particularly strong and sustained dilations occurred when participants managed to perform Go responses to aversive cues. Conversely, no such dilations occurred when they managed to inhibit responses to Win cues. These results suggest that pupil diameter does not reflect response conflict per se nor the inhibition of prepotent responses, but specifically effortful action invigoration as needed to overcome aversive inhibition. We discuss our results in the context of the “value of work” theory of striatal dopamine.
A MeerKAT Polarization Survey of Southern Calibration Sources
Authors: Taylor A. R. , Legodi L. S. 
Published: May 2024

Abstract
We report on full-Stokes L-band observations of 98 MeerKAT calibration sources. Linear polarization is detected in 71 objects above a fractional level of 0.2%. We identify ten sources with strong fractional linear polarization and low Faraday rotation measure that could be suitable for wide-band absolute polarization calibration. We detect significant circular polarization from 24% of the sample down to a detection level of 0.07%. Circularly polarized emission is seen only for flat spectrum sources α > −0.5. We compare our polarized intensities and Faraday synthesis results to data from the NVSS at 1400 MHz and the ATCA SPASS survey at 2300 MHz. NVSS data exist for 54 of our sources and SPASS data for 20 sources. The percent polarization and rotation measures from both surveys agree well with our results. The residual instrumental linear polarization for these observations is measured at 0.16%, and the residual instrumental circular polarization is measured at 0.05%. These levels may reflect either instabilities in the relative bandpass between the two polarization channels with either time or antenna orientation, or atmospheric/ionospheric variations with pointing direction. Tracking of the hourly gain solutions on J0408-6545 after transfer of the primary gain solutions suggests a deterioration of the gain stability by a factor of several starting about 2 hr after sunrise. This suggests that observing during the nighttime could dramatically improve the precision of polarization calibration.
The Lorentz Force at Work: Multiphase Magnetohydrodynamics throughout a Flare Lifespan
Authors: Ruan Wenzhi , Keppens Rony , Yan Limei , Antolin Patrick 
Published: May 2024

Abstract
The hour-long, gradual phase of solar flares is well observed across the electromagnetic spectrum, demonstrating many multiphase aspects, where cold condensations form within the heated post-flare system, but a complete 3D model is lacking. Using a state-of-the-art 3D magnetohydrodynamic simulation, we identify the key role played by the Lorentz force through the entire flare lifespan, and show that slow variations in the post-flare magnetic field achieve the bulk of the energy release. Synthetic images in multiple passbands closely match flare observations, and we quantify the role of conductive, radiative, and Lorentz force work contributions from flare onset to decay. This highlights how the non-force-free nature of the magnetic topology is crucial to trigger Rayleigh–Taylor dynamics, observed as waving coronal rays in extreme ultraviolet observations. Our C-class solar flare reproduces multiphase aspects such as post-flare coronal rain. In agreement with observations, we find strands of cooler plasma forming spontaneously by catastrophic cooling, leading to cool plasma draining down the post-flare loops. As there is force balance between magnetic pressure and tension and the plasma pressure in gradual-phase flare loops, this has potential for coronal seismology to decipher the magnetic field strength variation from observations.
An Eccentric Planet Orbiting the Polar V808 Aurigae

Published: May 2024

Abstract
We analyze 15 yr of eclipse timings of the polar V808 Aur. The rapid ingress/egress of the white dwarf and bright accretion region provide timings as precise as a few tenths of a second for rapid cadence photometric data. We find that between 2015 and 2018, the eclipse timings deviated from a linear ephemeris by more than 30 s. The rapid timing change is consistent with the periastron passage of a planet in an eccentric orbit about the polar. The best-fit orbital period is 11 ± 1 yr and we estimate a projected mass of

Jupiter masses. We also show that the eclipse timings are correlated with the brightness of the polar with a slope of 1.1 s mag−1. This is likely due to the change in the geometry of the accretion curtains as a function of the mass transfer rate in the polar. While an eccentric planet offers an excellent explanation to the available eclipse data for V808 Aur, proposed planetary systems in other eclipsing polars have often struggled to accurately predict future eclipse timings.
Laser Irradiation of Carbonaceous Chondrite Simulants: Space-weathering Implications for C-complex Asteroids
Authors: López-Oquendo Andy J. , Loeffler Mark J. , Trilling David E. 
Published: May 2024

Abstract
Surfaces of carbonaceous asteroids (C-complex) have shown diverse, contrasting spectral variations, which may be related to space weathering. We performed laser irradiation experiments on CI and CM simulant material under vacuum to mimic the spectral alteration induced by micrometeorite impacts. We used in situ ultraviolet-visible and near-infrared reflectance spectroscopy to analyze spectral alterations in response to pulsed laser irradiation, as well as scanning electron microscopy and X-ray photoelectron spectroscopy to search for microstructural and compositional changes. Laser irradiation causes an increase in spectral slope (reddening) and a decrease in the albedo (darkening), and these changes are stronger in the ultraviolet-visible region. These spectral changes are likely driven by the excess iron found in the altered surface region although other factors, such as the observed structural changes, may also contribute. Additionally, while the 0.27 μm band appears relatively stable under laser irradiation, a broad feature at 0.6 μm rapidly disappears with laser irradiation, suggesting that space weathering may inhibit the detection of any feature in this spectral region, including the 0.7 μm band, which has typically been used an indicator of hydration. Comparing our laboratory results with optical spectrophotometry observations of C-complex asteroids, we find that the majority of objects are spectrally red and possess colors that are similar to our irradiated material rather than our fresh samples. Furthermore, we also find that “younger” and “older” C-complex families have similar colors, suggesting that the space-weathering process is near equal or faster than the time it takes to refresh the surfaces of these airless bodies.

The genus Striglina is the most species-rich genus in the subfamily Striglininae, which includes about 80 species and subspecies and it has always been a popular research taxon within Thyrididae.
Two new species of the genus Striglina Guenée, 1877, S. whalleyi sp. nov. and S. pararubricans sp. nov. from China are described and illustrated. Striglina whalleyi sp. nov. is similar to S. irresecta obscura Whalley, 1976, but its wing ground colour is lighter and the sacculus process is shorter. Striglina pararubricans sp. nov. is similar to S. rubricans, but the fore-wing is narrower, the uncus processes and sacculus process are longer. Holotypes are deposited in the Department of Entomology, College of Plant Protection, South China Agricultural University, Guangzhou.
Assessment of CXCL13 plasma level in chronic lymphocytic leukemia and its relation to other prognostic markers
Authors: Shareef Omer Muhi , Hameed Bassam Muhammad 
Published: May 2024

Abstract:

BACKGROUND:
Chronic lymphocytic leukemia is a mature B-cell malignancy where there is a progressive accumulation of leukemic cells with a distinctive immunophenotype as consequence to defective apoptosis and survival signals derived from the microenvironment. CXC chemokine ligand 13 (CXCL13) chemokines have recently emerged as crucial orchestrators for lymphocyte trafficking and activation. These secreted polypeptides exert their function by binding to specific cell surface receptors and can be divided into two categories: homeostatic and inflammatory. The CXCL13 is an efficacious attractant of naive B-cells in vitro and has been shown to be produced constitutively by stromal cells in lymphoid follicles of human lymph nodes. The CXCL13-CXCR5 axis has been previously shown to contribute to the progression of several malignancies and possibly CLL relapse.

OBJECTIVE:
The aim of this study to compare the plasma level of CXCL13 in a patient with CLL with healthy normal control and to correlate the plasma level of CXCL13 to beta-2 microglobulin (β2 M) and other hematological parameters in CLL.

PATIENTS, MATERIALS AND METHODS:
This cross-sectional study was conducted on 50 CLL patients who were newly diagnosed. A total of 30 healthy individuals were included in this study as a control group. Measurement of plasma CXCL13 and beta-2 microglobulin levels was done by the enzyme-linked immunosorbent assay.

RESULTS:
Fifty CLL patients were studied and compared with thirty control group of healthy individuals. The mean level of CXCL13 was 67.48 pg/ml in CLL patients while it was 69.2 pg/ml in control, so it is statistically not significant (P = 0.363). The mean level of β2 M was 50.89 ug/ml in CLL patients while it was 50.59 ug/ml in control, so it is statistically not significant (P = 0.702). The percentage of stage A of CLL patients was 22.44%, stage B was18.36%, and stage C was 10.20%. The percentages of lymphadenopathy, splenomegaly, and hepatomegaly were 66%, 32%, and 16%, respectively. The mean of malignant cell percentage in stage A was 55.18%; in stage B, it was 69.28%; and in stage C, it was 81%, so it is statistically significant (P < 0.001). CXCL13 shows no statistically significant between Cd38+ and CD38− and P value was 0.950.

CONCLUSIONS:
There was no correlation in level of CXCL13 between the CLL group and the control group. There was no correlation in level of CXCL13 and β2 M in the CLL group.
