Authors: Anderson‐Cook Christine M. , Lu Lu , Gramacy Robert B. , Jones‐Farmer L. Allison , Montgomery Douglas C. , Woodall William H. 
Published: February 2024

AbstractOne of the tasks required of most statistics researchers and academic faculty is to publish their innovative ideas in the peer‐reviewed literature. In this paper, we provide guidance about the different stages of the process as experienced authors and offer advice from those who hold the decision about the success or failure of these papers, namely the editors of applied statistics journals. The paper is organized into four sections focusing on the different stages of publishing: (1) Planning what to write about, where to submit and how to organize the paper; (2) The process of writing the paper; (3) Interpreting and responding to peer‐reviews from the journal editors and referees to prepare for resubmission; and (4) General comments about the publication process, including collaboration and mentoring. Each section starts with fundamentals provided by the moderators (C.A.C. and L.L.) on key aspects to consider on each topic and then is followed with discussion from some current and past editors of impactful journals in the field of applied statistics. Our hope is that this collection of insights may help accelerate learning about the process for young researchers and help all researchers to understand some of the important often‐unspoken aspects of the process.
Tunable third‐order NLO properties of acene derivatives with molecular structural modification

Published: February 2024

AbstractThe substitution of heteroatoms and the expansion of π‐conjugated units have significant effects on the photoelectric properties of polycyclic aromatic hydrocarbons (PAHs). In this study, based on the experimental molecule PBC, 10 acene derivatives containing the pyrrole group were designed by three strategies: (1) changing the connection position of the pyrrole group, (2) exchanging the position of the N atom, and (3) increasing the length of the π‐linker. Density functional theory (DFT) was used to optimize the molecular geometric structure. Time‐dependent density functional theory (TD‐DFT) was used to calculate the relevant parameters of the excited states. The results show that both of the pyrrole group and the N atom in the para‐position, and the addition of the π‐linker can reduce the energy gap, cause redshift of the linear absorption peak, and increase the two photon absorption (TPA) cross‐section. The analyses of the charge density difference (CDD) and the charge‐transfer matrix (CTM) proved that the electron transfer is mainly concentrated in the π‐linker. Moreover, the participation of the multi‐ring skeleton on both sides decreases gradually with the increase of the length of the π‐linker. The length of the π‐linker changes the dominant transition channel and intramolecular charge‐transfer (ICT) characteristics of TPA, thus affecting the transition dipole moments and nonlinear absorption properties. The second hyperpolarizability of the designed molecule PBI5‐p5 is also significantly superior to that of similar materials reported. It is expected that the above molecular design strategies and comprehensive analysis of nonlinear optical (NLO) properties could provide theoretical support for the research on acene derivatives.

Published: February 2024

AbstractThis study focuses on the synthesis and characterization of a series of conjugated porous polymers (CPPs) based on a 2,4,6‐tris(5‐ethynylthiophen‐2‐yl)‐1,3,5‐triazine (TT) core moiety. TT was coupled with several conjugated building blocks as comonomers, including naphthodithiophene, benzodithiophene, bithiophene, tetraphenyl porphyrin, azulene, and perylene diimide, utilizing the Sonogashira‐coupling reaction to produce narrow band gap (1.73–2.19 eV) CPPs. The solid‐state UV‐visible spectra demonstrated broad absorption in 350 nm to 900 nm region, indicating extended π‐conjugation in the polymers. The photophysical properties of the polymers have been tuned by the judicious choice of comonomer. The obtained CPPs exhibit excellent thermal stability, reaching as high as 500 °C, and porosity insights reveal dominance of mesopores and macropores. Morphological studies reveal that 2‐ethylhexyl substituted perylene diimide hinder the stacking amongst the polymeric backbone, resulting in featureless aggregates, whereas the cyclohexyl group on perylene diimide results in well‐defined nanofibrous morphology. These narrow band‐gap CPPs hold promise for applications in energy storage, organic electronics, photocatalysis and sensing technologies.
Balanced knowledge distribution among software development teams—Observations from open‐ and closed‐source software development

Published: February 2024

SummaryIn software development, developer turnover is among the primary reasons for project failures, leading to a great void of knowledge and strain for newcomers. Unfortunately, no established methods exist to measure how the problem domain knowledge is distributed among developers. Awareness of how this knowledge evolves and is owned by key developers in a project helps stakeholders reduce risks caused by turnover. To this end, this paper introduces a novel, realistic representation of problem domain knowledge distribution: the ConceptRealm. To construct the ConceptRealm, we employ a latent Dirichlet allocation model to represent textual features obtained from 300 K issues and 1.3 M comments from 518 open‐source projects. We analyze whether the newly emerged issues and developers share similar concepts or how aligned the individual developers' concepts are with the team over time. We also investigate the impact of leaving developers on the frequency of concepts. Finally, we also evaluate the soundness of our approach on a closed‐source software project, thus allowing the validation of the results from a practical standpoint. We find out that the ConceptRealm can represent the problem domain knowledge within a project and can be utilized to predict the alignment of developers with issues. We also observe that projects exhibit many keepers independent of project maturity and that abruptly leaving keepers correlates with a decline of their core concepts as the remaining developers cannot quickly familiarize themselves with those concepts.

AbstractA simple and robust high‐performance liquid chromatography (HPLC) method was developed for organic impurities of hydroxyzine hydrochloride in pharmaceuticals. The developed method was designed to estimate all organic impurities of hydroxyzine. The HPLC separation was achieved using C18 column (150 × 3.9 mm, 5 μm) along with a binary gradient consisting of mobile phases A (0.1%, trifluoroacetic acid in purified water) and B (0.05%, trifluoroacetic acid in acetonitrile), a flow rate of 0.7–mL/min, a column temperature of 30°C and a sample temperature of 25°C. The detection wavelength used was 230 nm for the estimation of impurity‐A, impurity‐B, and all unspecified impurities and degradation products, whereas impurity‐C was quantitated using 254 nm. The stability‐indicating property of the developed HPLC technique was assessed using stress testing conditions of hydrolysis, oxidation, thermal, photo‐light, and humidity. The validation study was performed for the limit of detection and limit of quantification, linearity, and recoveries were 0.03%, 0.05%, and 0.1132–2.9920 μg/mL (R2 > 0.999), and 84.09%–109.74%, respectively. The proposed method is highly suitable for the determination of assay, organic impurities, and degradation products of the hydroxyzine. The chemical structure of degradation product 1 (hydroxyzine N‐Oxide) and degradation product 2 (O‐Acetyl hydroxyzine) were identified with the supporting data of LC‐mass spectrometry (LC‐MS) and high‐resolution MS.
Finding constraints to foster creativity in language learning tasks: An autoethnographic approach
Authors: Tin Tan Bee 
Published: February 2024

AbstractTeachers often repeat language learning tasks and materials with students year after year. Although some tasks do not render satisfactory outcomes, students' performances can serve as valuable historical autoethnographic data that teachers can reflect on to improve their teaching materials and language learning tasks. In this article, using autoethnography as a pedagogical tool, I share my thinking and experiences regarding one task type (the simile task), which I have used with students over the years to develop creative language use (language creativity). I reflect on various similes produced and attempt to discover how to redesign the somewhat imperfect task to optimize creative language use. In particular, I try to find new constraints that can be set up to funnel the creative behaviour of the teacher and students. Before promoting students' creativity, teachers must nurture their creativity under various self‐imposed constraints. Teachers' personal experience is a valuable source when implementing creative language teaching. This article shows two task constraints that can be set up to stimulate creativity in language learning tasks: exclusionary constraints (avoiding confirmation‐based salient patterns) and focusing constraints (requiring the use of violation‐based salient patterns). It also shows how we can identify micro‐constraints to be excluded or focused on.
History and Education of the Sacred: Black Girls and Curricular Violence in Literacy Learning
Authors: Brooks Jennifer N. , Muhammad Gholdy E. 
Published: February 2024

AbstractBlack girls and their literacies are genius. Yet, education, as we know it, does not consistently offer spaces for Black girls to be loved and honored. This form of neglect extends to literacy classrooms. As displayed in the news and research, Black girls experience abuse within the confines of educational walls. Educational violence against Black girls is a byproduct of dehumanization and devaluation, and it stems from history. The underlying stereotypical conditioning centered around the dehumanized, oversexualized, unladylike, Black girl may rationalize why educators overlook them when creating literacy curricula. When classroom teachers rely on these biases, the need for an intentional literacy curriculum to support and uplift the literacy development of Black girls may seem unimportant, which in turn leaves Black girls at an educational disadvantage. This paper will discuss social and educational historical factors that have problematized literacy education for Black girls. As a resolution, we unpack the Black Girls Literacy Framework to respond to educational and literacy inequities.
Embeddedness of min–max CMC hypersurfaces in manifolds with positive Ricci curvature

AbstractWe prove that on a compact Riemannian manifold of dimension 3 or higher, with positive Ricci curvature, the Allen–Cahn min–max scheme in Bellettini and Wickramasekera (The Inhomogeneous Allen–Cahn Equation and the Existence of Prescribed-Mean-Curvature Hypersurfaces, 2020), with prescribing function taken to be a non-zero constant $$\lambda $$

More precisely, we prove that the interface arising from said min–max contains no even-multiplicity minimal hypersurface and no quasi-embedded points (both of these occurrences are in principle possible in the conclusions of Bellettini and Wickramasekera, 2020). The immediate geometric corollary is the existence (in ambient manifolds as above) of embedded, closed $$\lambda $$
λ
-CMC hypersurfaces (with Morse index 1) for any prescribed non-zero constant $$\lambda $$

The Photoprotective Behavior of a Motile Benthic Diatom as Elucidated from the Interplay Between Cell Motility and Physiological Responses to a Light Microgradient Using a Novel Experimental Setup

Published: February 2024

AbstractIt has long been hypothesized that benthic motile pennate diatoms use phototaxis to optimize photosynthesis and minimize photoinhibitory damage by adjusting their position within vertical light gradients in coastal benthic sediments. However, experimental evidence to test this hypothesis remains inconclusive, mainly due to methodological difficulties in studying cell behavior and photosynthesis over realistic spatial microscale gradients of irradiance and cell position. In this study, a novel experimental approach was developed and used to test the hypothesis of photosynthesis optimization through motility, based on the combination of single-cell in vivo chlorophyll fluorometry and microfluidic chips. The approach allows the concurrent study of behavior and photosynthetic activity of individual cells of the epipelic diatom species Craspedostauros britannicus exposed to a light microgradient of realistic dimensions, simulating the irradiance and distance scales of light microgradients in benthic sediments. Following exposure to light, (i) cells explored their light environment before initiating light-directed motility; (ii) cells used motility to lower their light dose, when exposed to the highest light intensities; and (iii) motility was combined with reversible non-photochemical quenching, to allow cells to avoid photoinhibition. The results of this proof-of-concept study not only strongly support the photoprotective nature of photobehavior in the studied species but also revealed considerable variability in how individual cells reacted to a light microgradient. The experimental setup can be readily applied to study motility and photosynthetic light responses of other diatom species or natural assemblages, as well as other photoautotrophic motile microorganisms, broadening the toolset for experimental microbial ecology research.
Ion-concentration gradients induced by synaptic input increase the voltage depolarization in dendritic spines
Authors: Eberhardt Florian 
Published: February 2024

AbstractThe vast majority of excitatory synaptic connections occur on dendritic spines. Due to their extremely small volume and spatial segregation from the dendrite, even moderate synaptic currents can significantly alter ionic concentrations. This results in chemical potential gradients between the dendrite and the spine head, leading to measurable electrical currents. In modeling electric signals in spines, different formalisms were previously used. While the cable equation is fundamental for understanding the electrical potential along dendrites, it only considers electrical currents as a result of gradients in electrical potential. The Poisson-Nernst-Planck (PNP) equations offer a more accurate description for spines by incorporating both electrical and chemical potential. However, solving PNP equations is computationally complex. In this work, diffusion currents are incorporated into the cable equation, leveraging an analogy between chemical and electrical potential. For simulating electric signals based on this extension of the cable equation, a straightforward numerical solver is introduced. The study demonstrates that this set of equations can be accurately solved using an explicit finite difference scheme. Through numerical simulations, this study unveils a previously unrecognized mechanism involving diffusion currents that amplify electric signals in spines. This discovery holds crucial implications for both numerical simulations and experimental studies focused on spine neck resistance and calcium signaling in dendritic spines.
Experimental strategy for the preparation of adsorbent materials from torrefied palm kernel shell oriented to CO2 capture

Published: February 2024

AbstractIn this study, an experimental strategy to obtain biochar and activated carbon from torrefied palm kernel shell as an efficient material for CO2 removal was evaluated. Biochar was obtained by slow pyrolysis of palm kernel shell at different temperatures (350 °C, 550 °C, and 700 °C) and previously torrefied palm kernel shell at different temperatures (220 °C, 250 °C, and 280 °C). Subsequently, activated carbons were prepared by physical activation with CO2 from previously obtained biochar samples. The CO2 adsorption capacity was measured using TGA. The experimental results showed that there is a correlation between the change in the O/C and H/C ratios and the functional groups –OH and C=O observed via FTIR in the obtained char, indicating that both dehydration and deoxygenation reactions occur during torrefaction; this favors the deoxygenation reactions and makes them faster through CO2 liberation during the pyrolysis process. The microporous surface area shows a significant increase with higher pyrolysis temperatures, as a product of the continuous carbonization reactions, allowing more active sites for CO2 removal. Pyrolysis temperature is a key factor in CO2 adsorption capacity, leading to a CO2 adsorption capacity of up to 75 mg/gCO2 for biochar obtained at 700 °C from non-torrefied palm kernel shell (Char700). Activated carbon obtained from torrefied palm kernel shell at 280 °C (T280-CHAR700-AC) exhibited the highest CO2 adsorption capacity (101.9 mg/gCO2). Oxygen-containing functional groups have a direct impact on CO2 adsorption performance due to electron interactions between CO2 and these functional groups. These findings could provide a new experimental approach for obtaining optimal adsorbent materials exclusively derived from thermochemical conversion processes.
The Law of Non-contradiction and Global Philosophy of Religion
Authors: Loke Andrew Ter Ern 
Published: February 2024

AbstractThis article focuses on the applications of philosophical logic in the discipline of philosophy of religion of both ‘Eastern’ and ‘Western’ traditions, in which the problem of apparent ontological contradictions can be found. A number of philosophers have proposed using the work of those non-classical logicians who countenance the violation of the law of non-contradiction (LNC) to address this problem. I discuss (1) whether classical or non-classical account of logic is universal in applying to all true theories, and (2) whether there might be extra-logical considerations which affect what is the correct account of logic for the doctrines in question. With regard to Jc Beall’s application of non-classical (FDE) logic to the doctrine of the Incarnation, I argue using the evidence from the writings of church fathers that the meaning of negation found in the core claims of the doctrine of the Incarnation should not be interpreted in accordance with Beall’s FDE account, and that this extra-logical consideration refutes Beall’s project. Moreover, the FDE’s acceptance of the possibility of statements that are both true and false is contrary to what is allowed by the definition of negation in classical logic; therefore (contrary to Beall), Beall is in fact using a different definition of negation compared with the definition used by the classical account. I develop this point in interaction with contemporary philosophy of religion literature and explain its implications and significance for this discipline.
Neuroprotective Effect of a Multistrain Probiotic Mixture in SOD1G93A Mice by Reducing SOD1 Aggregation and Targeting the Microbiota-Gut-Brain Axis

Published: February 2024

AbstractAmyotrophic lateral sclerosis (ALS) is a devastating neurodegenerative disease characterized by the selective loss of motor neurons. A bidirectional communication system known as the “microbiota-gut-brain” axis has a regulatory function in neurodegenerative disorders. The impact of probiotics on ALS through the “microbiota-gut-brain” axis remains uncertain. A longitudinal investigation was conducted to examine the alterations in the structure of the ileum and colon in mutant superoxide dismutase 1 (SOD1G93A) transgenic mice models of ALS by using immunofluorescence and Western blotting. Subsequently, the mice were administered a multistrain probiotic mixture (LBE) or vehicle orally, starting from 60 days of age until the terminal stage of the disease. The effects of these agents on the behavior, gut microbiota, microbial metabolites, and pathological processes of the spinal and intestine of SOD1G93A mice were analyzed, with a focus on exploring potential protective mechanisms. SOD1G93A mice exhibit various structural abnormalities in the intestine. Oral administration of LBE improved the proinflammatory response, reduced aberrant superoxide dismutase 1 (SOD1) aggregation, and protected neuronal cells in the intestine and spinal cord of SOD1G93A mice. Furthermore, LBE treatment resulted in a change in intestinal microbiota, an increase in short-chain fatty acid levels, and an enhancement in autophagy flux. SOD1G93A mice exhibited various structural abnormalities in the intestine. LBE can improve the proinflammatory response, reduce aberrant SOD1 aggregation, and protect neuronal cells in the spinal cord and intestine of SOD1G93A mice. The positive effect of LBE can be attributed to increased short-chain fatty acids and enhanced autophagy flux.
Bedingungslose Jugendhilfe, bedingungslose Solidarität
Authors: Schmitt Caroline , Thalheim Vinzenz 
Published: February 2024

ZusammenfassungIn diesem Beitrag wird die gegenwärtige Kinder- und Jugendhilfe in Deutschland aus einer solidaritätsinspirierten Perspektive gelesen. Leitende Fragen sind, wer in der Kinder- und Jugendhilfe als Empfänger_in von Hilfe gedacht und adressiert wird, wer unter welchen Bedingungen Leistungen beanspruchen kann, wer hiervon ausgeschlossen ist, und wie ein bedingungsloses Verständnis von Solidarität die bisherigen Debatten erweitern kann. Ausgehend von theoretischen Überlegungen und empirischen Bezugnahmen wird im Folgenden eine transtopische Idee für eine bedingungslos solidarische Kinder- und Jugendhilfe – als Anstoß für eine Debatte auch in weiteren Arenen des Sozialen – entfaltet.
