AbstractThe present involves the development of an accurate, specific, and precise high‐performance thin‐layer chromatographic method for the identification and quantification of three markers apigenin, oleanolic acid, and β‐sitosterol in Clerodendrum serratum (Bharangi) root extract. The thin layer chromatographic development was carried out using an aluminum plate, pre‐coated with silica gel 60 F254 with toluene–chloroform‐ethyl acetate‐formic acid (5:4:1:0.1 v/v/v/v) as the mobile phase. Densitometric quantification was performed at 334 nm for apigenin and 662 nm for oleanolic acid and β‐sitosterol after derivatization with anisaldehyde‒sulfuric acid reagent. The optimized mobile phase resulted in chromatographic separation of apigenin, oleanolic acid, and β‐sitosterol bands at Rf of 0.19, 0.50, and 0.63, respectively. The method was found to be linear in the concentration range of 200–1200 ng/band for apigenin, and 400–2400 ng/band for oleanolic acid and β‐sitosterol, respectively. The recoveries were found to be 99.34%–99.92% for apigenin, 99.38%–99.81% for oleanolic acid, and 99.49%–99.66% for β‐sitosterol. The optimized method was found to be accurate, reproducible, robust, and specific and it was applied for the quantification of apigenin, oleanolic acid, and β‐sitosterol in hydroalcoholic root extract of Clerodendrum serratum.

ABSTRACTObjectiveMaternal cardiac function plays a crucial role in placental function and development. The maternal hemodynamic changes in twin pregnancy are more pronounced than those in singleton pregnancy, presumably due to a greater plasma volume expansion. In view of the correlation between maternal cardiac and placental function, it is plausible that chorionicity could influence maternal cardiac function. The aim of this study was to compare the longitudinal maternal hemodynamic changes between uncomplicated dichorionic (DC) and monochorionic (MC) twin pregnancies and in comparison to singleton pregnancies.MethodsIncluded in the study were 40 MC diamniotic and 35 DC diamniotic uncomplicated twin pregnancies. These were compared with a group of 294 healthy singleton pregnancies from a previous cross‐sectional study. All participants underwent a hemodynamic evaluation using an Ultrasound Cardiac Output Monitor (USCOM®), at three different stages in pregnancy (11–15 weeks, 20–24 weeks and 29–33 weeks). The following parameters were recorded: mean arterial pressure (MAP), stroke volume (SV), stroke volume index (SVI), heart rate, cardiac output (CO), cardiac index (CI), systemic vascular resistance (SVR), systemic vascular resistance index (SVRI), stroke volume variation, Smith–Madigan inotropy index (INO) and potential‐to‐kinetic‐energy ratio (PKR).ResultsIn the first trimester, DC and MC twin pregnancies showed lower MAP, SVR and PKR and higher CO and SV in comparison to singleton pregnancy. In the second trimester, maternal CO (8.33 vs 7.30 L/min, P = 0.03) and CI (4.52 vs 4.00 L/min/m2, P = 0.02) were significantly higher in MC compared with DC twin pregnancy. In the third trimester, compared with in singleton pregnancy, women with MC twin pregnancy showed significantly higher PKR (24.06 vs 20.13, P = 0.03) and SVRI (1837.20 vs 1698.48 dynes × s/cm5/m2, P = 0.03), and significantly lower SV (78.80 vs 88.80 mL, P = 0.01), SVI (42.79 vs 50.31 mL/m2, P < 0.01) and INO (1.70 vs 1.87 W/m2, P = 0.03); these differences were not observed between DC twin and singleton pregnancies.ConclusionsMaternal cardiovascular function undergoes significant change during uncomplicated twin pregnancy and chorionicity influences maternal hemodynamics. In both MC and DC twin pregnancy, hemodynamic changes are detectable as early as the first trimester, showing higher maternal CO and lower SVR compared with singleton pregnancy. In DC twin pregnancy, the maternal hemodynamics remain stable during the rest of pregnancy. In contrast, in MC twin pregnancy, the rise in maternal CO continues in the second trimester in order to sustain the greater placental growth. There is a subsequent crossover, with a reduction in cardiovascular performance during the third trimester. © 2023 International Society of Ultrasound in Obstetrics and Gynecology.
First computation of Mueller Tang processes using a full NLL BFKL approach

Published: June 2023

Abstract
We present the full next-to-leading order (NLO) prediction for the jet-gap-jet cross section at the LHC within the BFKL approach. We implement, for the first time, the NLO impact factors in the calculation of the cross section. We provide results for differential cross sections as a function of the difference in rapidity and azimuthal angle betwen the two jets and the second leading jet transverse momentum. The NLO corrections of the impact factors induce an overall reduction of the cross section with respect to the corresponding predictions with only LO impact factors.We note that NLO impact factors feature a logarithmic dependence of the cross section on the total center of mass energy which formally violates BFKL factorization. We show that such term is one order of magnitude smaller than the total contribution, and thus can be safely included in the current prediction without a need of further resummation of such logarithmic terms.Fixing the renormalization scale μR according to the principle of minimal sensitivity, suggests μR about 4 times the sum of the transverse jet energies and provides smaller theroretical uncertainties with respect to the leading order case.
Charges in the UV completion of neutral electrodynamics
Authors: Benedetti Valentin , Casini Horacio , Magán Javier M. 
Published: June 2023

Abstract
A theory with a non-compact form-symmetry is described by two closed form fields of degrees k and d – k. Effective theory examples are non-linear electrodynamics, a photon field coupled to a neutron field, and a low energy Goldstone boson. We show these models cannot be completed in the UV without breaking the non-compact form-symmetry down to a compact one. This amounts to the existence of electric or magnetic charges. A theory with an unbroken non-compact k-form symmetry is massless and free.
Clock-talk: have we forgotten about geographic variation?

Published: June 2023

AbstractWyeomyia smithii, the pitcher-plant mosquito, has evolved from south to north and from low to high elevations in eastern North America. Along this seasonal gradient, critical photoperiod has increased while apparent involvement of the circadian clock has declined in concert with the evolutionary divergence of populations. Response to classical experiments used to test for a circadian basis of photoperiodism varies as much within and among populations of W. smithii as have been found in the majority of all other insects and mites. The micro-evolutionary processes revealed within and among populations of W. smithii, programmed by a complex underlying genetic architecture, illustrate a gateway to the macro-evolutionary divergence of biological timing among species and higher taxa in general.

AbstractThe “floating ball sign” (FBS) is a rarely described visual phenomenon found in mature ovarian teratoma imaging. It is characterized by the presence of movable, spherical areas within the cystic component of a tumor. Such visualization is possible both in cross-sectional imaging and ultrasonography. To evaluate the incidence of FBS in the pediatric population with regard to patients’ age and tumor size. This is a retrospective study of pediatric patients operated on in a tertiary pediatric surgical center between January 2009 and December 2022 due to mature ovarian teratoma; the medical records were reviewed for the age at diagnosis, recurrences, tumor size, and their characteristics in preoperative imaging. Eighty-three patients (mean age 14, range 0–17) out of 91 met the inclusion criteria for the analysis. Eighty-seven operations on 90 ovaries were performed. Preoperatively 38 patients underwent CT, 13 MRI, and 39 received only the ultrasound examination. The FBS was identified in preoperative imaging diagnostics in 3 (3.3%) girls (14, 16 and 17 years of age). The average largest tumor dimension and volume were 142 mm and 1268 cc in the FBS group, and 73 mm and 252 cc in the remaining group, respectively. FBS tumors usually reach large sizes. Although the sign is rare in children, there are no scientific reports of its occurrence in the first life decade. Color flow mapping and cross-sectional imaging play a pertinent role in distinguishing this uncommon pattern from a malignant mass and enable the selection of an appropriate surgical approach.

AbstractCOVID-19 has impacted populations across the globe and has been a major cause of morbidity and mortality. Influenza is another potentially deadly respiratory infection that affects people worldwide. While both of these infections pose major health threats, little is currently understood regarding the clinical aspects of influenza and COVID-19 co-infection. Our objective was to therefore provide a systematic review of the clinical characteristics, treatments, and outcomes for patients who are co-infected with influenza and COVID-19. Our review, which was conducted in accordance with the Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) guidelines, involved searching for literature in seven different databases. Studies were eligible for inclusion if they included at least one co-infected patient, were available in English, and described clinical characteristics for the patients. Data were pooled after extraction. Study quality was assessed using the Joanna Brigg’s Institute Checklists. Searches produced a total of 5096 studies, and of those, 64 were eligible for inclusion. A total of 6086 co-infected patients were included, 54.1% of whom were male; the mean age of patients was 55.9 years (SD = 12.3). 73.6% of cases were of influenza A and 25.1% were influenza B. 15.7% of co-infected patients had a poor outcome (death/deterioration). The most common symptoms were fever, cough, and dyspnea, with the most frequent complications being pneumonia, linear atelectasis, and acute respiratory distress syndrome. Oseltamivir, supplemental oxygen, arbidol, and vasopressors were the most common treatments provided to patients. Having comorbidities, and being unvaccinated for influenza, were shown to be important risk factors. Co-infected patients show symptoms that are similar to those who are infected with COVID-19 or influenza only. However, co-infected patients have been shown to be at an elevated risk for poor outcomes compared to mono-infected COVID-19 patients. Screening for influenza in high-risk COVID-19 patients is recommended. There is also a clear need to improve patient outcomes with more effective treatment regimens, better testing, and higher rates of vaccination.
The Compressive and Shear Characteristics of Miura-ori Forms as Core Materials of Sandwich Structures

Published: June 2023

AbstractThe mechanical properties of Miura-ori foldcore metamaterials were studied using finite element simulations. The responses of foldcores with various topological parameters to quasi-static out-of-plane compression and shear loading were analyzed using the relative density as a governing parameter. The non-unique relationships between the core density and the materials’ strength in the examined loading directions were revealed, pointing out the strong influence of the Miura-ori topology. Linear relationships were established between the elastic moduli and relative densities of the Miura-ori metamaterials while power-law functions of the relative density with different exponent constants were established for the strength in different loading directions. It was shown that the Miura-ori materials possess the highest strength under shear in the $${X}_{1}-{X}_{3}$$

α
. In general, the difference between the two shear strengths increases when increasing the relative density by using thicker cell walls. It is noted that the strength of the Miura-ori materials as a function of the relative density is nearly constant with respect to the cell dimensions if the values of folding angle $${\gamma }_{0}$$

The mechanical characteristics of the Miura-ori material with equal relative density, which exhibits the highest strength among the analyzed origami models, are compared with the out-of-plane compression and shear responses of prismatic hexagonal honeycomb. It is observed that compression and shear responses of the honeycomb outperform the Miura-ori foldcore in all loading directions when considering large deformations.
Semidistrim Lattices

Published: June 2023

AbstractWe introducesemidistrim lattices, a simultaneous generalization of semidistributive and trim lattices that preserves many of their common properties. We prove that the elements of a semidistrim lattice correspond to the independent sets in an associated graph called theGalois graph, that products and intervals of semidistrim lattices are semidistrim and that the order complex of a semidistrim lattice is either contractible or homotopy equivalent to a sphere.Semidistrim lattices have a naturalrowmotionoperator, which simultaneously generalizes Barnard’s$\overline \kappa $map on semidistributive lattices as well as Thomas and the second author’s rowmotion on trim lattices. Every lattice has an associatedpop-stack sortingoperator that sends an elementxto the meet of the elements covered byx. For semidistrim lattices, we are able to derive several intimate connections between rowmotion and pop-stack sorting, one of which involves independent dominating sets of the Galois graph.
Economy or ecology: metaphor use over time in China’s Government Work Reports
Authors: Sun Ya , Kong Deyi , Zhou Chenmeng 
Published: June 2023

AbstractGovernment attention selectively distributed to various issues in policy-making processes is usually reflected in language, such as metaphors in political discourse. In addition, metaphor change may reveal how conceptualizations of major topics such as economy and ecology evolve over time. After self-building a corpus of China’s 45-year Government Work Reports, this study explores whether there is a difference in attention to topics of economy and ecology over time and investigates the diachronic change of metaphor use on them based on a modified framework for diachronic metaphor change analysis. Results show that attention to economy has been steadily decreasing while attention to ecology has been growing, and that there is an increasing tendency of using more economy and ecology metaphors. Metaphor change on the use of source domains is arranged on a continuum, ranging from constant use (war for economy and ecology, and journey and object for economy), incremental change (living organism and building for economy and ecology, and object for ecology) to fundamental change (building and living organism for ecology). This study may enrich the understanding of diachronic metaphor change by providing a Chinese perspective on the metaphor use in government discourse over time.
Changing Our Nature: Ethical Naturalism, Objectivity, and History
Authors: Congdon Matthew 
Published: June 2023

AbstractThis paper argues that Aristotelian ethical naturalism can combine two commitments that are often held to be incompatible: (a) a commitment to a strong form of ethical objectivity and (b) a thoroughgoing historicism about ethical value. The notions of species and life-form invoked by ethical naturalism do not, I argue, rely upon an ahistorical picture of human nature. I develop this idea by building upon Philippa Foot's defence of ethical naturalism in Natural Goodness. I go on to argue that linguistic changes in the ways we articulate the conditions of human flourishing can be understood, in some cases, as transforming those very conditions.
Clinical effectiveness of fluticasone furoate nasal spray for perennial allergic rhinitis in children: a comprehensive review
Authors: Rivera Paola Andrea 
Published: June 2023

Abstract

Objective
To assess the clinical effectiveness of fluticasone furoate nasal spray (FFNS) versus placebo on nasal symptoms and safety in children with perennial allergic rhinitis (AR).

Methods
A comprehensive review was conducted with data obtained from Medline and Embase databases up to April 2023. The population of interest was patients aged 2–12 years with perennial AR. The selection was limited to randomized controlled trials (RCTs), comparing FFNS with placebo. Outcomes of interest included the reflective total nasal symptoms scores (rTNSS) and safety. To assess the minimal clinically important difference for rTNSS, the Cohen’s guideline was used. If the pooled standardized mean difference (SMD) and the lower limit of the 95 percent confidence interval (CI) exceeded the threshold of −0.20, effects were considered clinically significant.

Results
Three RCTs (959 pediatric patients) were selected. One study evaluated the short-term use of FFNS, another evaluated the long-term use of FFNS, and another evaluated both the short-term and long-term use of FFNS. FFNS produced a statistically significant reduction over placebo in rTNSS (SMD −0.18; 95 percent CI −0.35 to −0.01, p = 0.03) in long-term treatment studies, but not in short-term treatment studies. However, since the mean reduction did not reach the minimum clinically important difference (SMD −0.20), these results were considered clinically not relevant. Safety outcomes with FFNS were similar to placebo.

Conclusions
The currently available evidence suggests that FFNS, 110 μg once daily, compared to placebo, does not produce a meaningful clinical effect on nasal symptom in children with perennial AR.

Abstract
We analysed the transmission of the human mpox virus in Spain by estimating the effective reproduction number of the disease from official surveillance data. Our computations show that this decreased steadily after an initial burst phase, dropping below 1 on July 12, and thus the outbreak was expected to reduce in the following weeks. Differences in trends were found across geographical regions of the country and across MSM and heterosexual populations.
Entrainment Makes Pollution More Likely to Weaken Deep Convective Updrafts Than Invigorate Them
Authors: Peters John M. , Lebo Zachary J. , Chavas Daniel R. , Su Chun‐Yian 
Published: June 2023

AbstractAre the results of aerosol invigoration studies that neglect entrainment valid for diluted deep convective clouds? We address this question by applying an entraining parcel model to soundings from tropical and midlatitude convective environments, wherein pollution is assumed to increase parcel condensate retention. Invigoration of 5%–10% and <2% is possible in undiluted tropical and midlatitude parcels respectively when freezing is rapid. This occurs because the positive buoyancy contribution from freezing is larger than the negative buoyancy contribution from condensate loading, leading to positive net condensate contribution to buoyancy. However, aerosol‐induced weakening is more likely when realistic entrainment rates occur because water losses from entrainment more substantially reduce the latent heating relative to the loading contribution. This leads to larger net negative buoyancy contribution from condensates in polluted than in clean entraining parcels. Our results demonstrate that accounting for entrainment is critical in conceptual models of aerosol indirect effects in deep convection.
Precipitation Rates of Electrons Interacting With Lower‐Band Chorus Emissions in the Inner Magnetosphere
Authors: Hsieh Yi‐Kai , Omura Yoshiharu 
Published: June 2023

AbstractElectrons trapped in the Earth's magnetic field can be scattered by whistler mode chorus emissions and precipitate into the Earth's upper atmosphere. Whistler mode chorus waves propagating in the Earth's inner magnetic field are usually observed with oblique wave normal angles (WNAs). In this study, we apply 12 chorus wave models with four various WNA sets (the maximum WNA are 0°, 20°, 60°, and 90% of resonance cone angles) and three wave amplitude sets (the maximum wave magnetic fields are 2.1 nT, 307 pT, and 49.4 pT) at L = 4.5. We use test‐particle simulations to trace electrons interacting with the waves and create Green's function sets for electrons initially at kinetic energies (K) 10–6,000 keV and equatorial pitch angles (α) 5°–89°. The simulation results show that in the 2.1 nT cases, the very oblique chorus waves contribute to more electron precipitation than the other three chorus wave models, especially at energies 50–100 keV. Checking the highest initial equatorial pitch angle of the precipitated electrons, we find that the very oblique chorus waves can precipitate electrons with α > 45°. In contrast, the other chorus waves can only precipitate electrons with α < 30°. Furthermore, the precipitation rates reveal that the anomalous trapping effect, which moves low equatorial pitch angle electrons away from the loss cone, in the oblique cases is much weaker than in the parallel case, resulting in higher precipitation rates. Finally, we derive the pitch angle scattering rates and verify the precipitation by nth cyclotron resonances with oblique chorus.
