Roles of Chain Architecture and Polymorphic Form in Tailoring the Properties of Surface‐Roughened Biaxially Oriented Polypropylene Films for Capacitors
Authors: Wang Jinqing , Yao Cheng , Huang Xinghua , Zhang Qin , Wang Ke 
Published: November 2023

AbstractSurface‐roughened films of biaxially oriented polypropylene (BOPP) are the most common polymeric dielectrics for oil‐immersed capacitors in electrical engineering. How to balance the roughness of film surfaces as well as the mechanical and high‐temperature electrical properties of film ontology remains a challenge. In this study, three grades of electrical specialized isotactic polypropylene resins with different distributions of molecular mass and stereo‐defects are surveyed for crystalline polymorphic behavior. The relationship of the chain microstructure, film surface topography, and mechanical and electrical properties determined through a comprehensive study of the resins’ chain architecture to the morphology of cast sheets and the characteristics of resultant films is elaborated. The chain features of wide molecular mass distribution and uniform stereo‐defects result in excellent β‐crystallization ability, leading to a fine, roughed topography on the film surface. The narrow distribution of molecular mass and the relatively high tacticity play a positive role in the physico‐mechanical properties of the films, especially in the improvement of breakdown strength at high temperatures. An appropriate chain architecture is vital to achieving the balance between surface topography and bulk performance in surface‐roughened BOPP films.
Minimization of eddy current artifacts in sequences with periodic dynamics
Authors: Flassbeck Sebastian , Assländer Jakob 
Published: November 2023

AbstractPurposeTo minimize eddy current artifacts in periodic pulse sequences with balanced gradient moments as, for example, used for quantitative MRI.Theory and MethodsEddy current artifacts in balanced sequences result from large jumps in k‐space. In quantitative MRI, one often samples some spin dynamics repeatedly while acquiring different parts of k‐space. We swap individual k‐space lines between different repetitions in order to minimize jumps in temporal succession without changing the overall trajectory. This reordering can be formulated as a traveling salesman problem and we tackle the discrete optimization with a simulated annealing algorithm.ResultsCompared to the default ordering, we observe a substantial reduction of artifacts in the reconstructed images and the derived quantitative parameter maps. Comparing two variants of our algorithm, one that resembles the pairing approach originally proposed by Bieri et al., and one that minimizes all k‐space jumps equally, we observe slightly lower artifact levels in the latter.ConclusionThe proposed reordering scheme effectively reduces eddy current artifacts in sequences with balanced gradient moments. In contrast to previous approaches, we capitalize on the periodicity of the sampled signal dynamics, enabling both efficient k‐space sampling and minimizing artifacts caused by eddy currents.

AbstractThis study presents data from the first years of permafrost monitoring in boreholes in the French Alps that started at the end of 2009 in the framework of the PermaFrance network. Nine boreholes are instrumented, among which six monitored permafrost temperature and active layer thickness (ALT) over >10 years. Ice‐poor and cold permafrost in high‐elevation north‐facing rock walls has warmed by up to >1°C at 10 m depth over the reference decade (2011–2020), whereas ice‐rich permafrost (rock glacier) temperatures remained stable. ALT has increased at four of the five boreholes for which decadal data are available. Summer 2015 marks a turning point in ALT regime and greatest ALT values were observed in 2022 (available for six boreholes), but thawing intensity did not show an obvious change. At one site with a layer of coarse blocks about 2 m thick, ALT was stable over 2018–2022 and response to the hottest years was dampened. Linear trends suggest an ALT increase of 2 m per decade for some ice‐poor rock walls, independently of their thermal state. The data reveal a variety of permafrost patterns and evolution with significant intraregional and local differences. Snow modulates the response to air temperature signal in various ways, with an important effect on near‐surface temperature trends and ALT: early snow melting in spring favors an ALT increase in rock walls. Maintaining these monitoring systems and understanding the physical processes controlling heterogeneous responses to climate signals is crucial to better assess permafrost dynamics and to adapt to its consequences.
Assessing the sterility and quality of gamma‐irradiated pepper weevils, Anthonomus eugenii (Coleoptera: Curculionidae), toward the development of the sterile insect technique

Published: November 2023

AbstractBACKGROUNDThe pepper weevil (PW), Anthonomus eugenii, is an economically significant pest of cultivated Capsicum spp. pepper crops in North America where it remains a challenge to manage because of its cryptic immature life stages. The sterile insect technique (SIT) is a genetic pest management tactic that relies on the release of insects that have been sterilized with ionizing radiation to lower the population reproductive rate. Toward developing an effective PW‐SIT program, this study has, for the first time, investigated the effects of gamma irradiation on the sterility and survival of this species.RESULTSAmong the array of doses tested, we found that pupal PW males and females irradiated at 110 Gy produced no adult offspring. Furthermore, females mated with a male irradiated at 110 Gy had high egg sterility (97.3%), and irradiated females nearly completely failed to lay eggs (97.5%). Individuals irradiated at this dose had a shortened lifespan (lethal time to 50% mortality values of 12 and 11 days for males and females, respectively) and quantitatively reduced spontaneous flight activity. The eclosion rate of PW pupae was not significantly reduced by any radiation treatment.CONCLUSIONThis study suggests that PWs irradiated at a gamma radiation dose of 110 Gy as pupae could feasibly be used in a PW‐SIT program, because both males and females were 100% sterile at this dose. These findings will inform the development of a SIT program that could considerably improve the sustainability and effectiveness of PW management in greenhouse and field pepper crops worldwide. © 2023 His Majesty the King in Right of Canada and The Authors.

Published: November 2023

AbstractTargeted modification of optical band gap is an important step for photovoltaic, sensing, and photocatalytic applications of metal‐organic frameworks (MOFs). Herein, effective optical band gap modification of MIL‐125‐NH2 has been realized by replacing titanium(Ti) in MIL‐125‐NH2 with cobalt(Co), iron(Fe), and copper(Cu), respectively. Optical band gaps of the original MIL‐125‐NH2, MIL‐125‐NH2‐Co25%, MIL‐125‐NH2‐Cu25%, and MIL‐125‐NH2‐Fe12.5% were determined by diffuse reflectance spectra (DRS) to be 2.62 eV, 2.06 eV, 2.2 eV, and 2.3 eV, respectively. The mechanism of band gap variation of MIL‐125‐NH2 was discussed to be related to the band gap and conduction band minimum of metal oxides of doped metals. The photoluminescence (PL) properties of the materials was investigated, and the PL performance was influenced by doping metals: MIL‐125‐NH2‐Co25%, MIL‐125‐NH2‐Cu25%, and MIL‐125‐NH2‐Fe12.5% exhibited red shifted compared to the original MIL‐125‐NH2. Moreover, the intensity of the PL was found to be decreased with doping metals. The origins of luminescence tunability was discussed accordingly.

AbstractIn search for new anticancer candidates, a new series of enamide fluorinated‐Schiff base derivatives were synthesized and confirmed by spectroscopic techniques as well as elemental microanalyses. The newly prepared compounds were evaluated for their cytotoxic activity on MCF‐7 breast adenocarcinoma cell line. The benzaldehyde Schiff base and furfural Schiff base derivatives (IC50=3.67±0.15 and 2.06±0.08 μM, respectively) were found to be the most potent molecules of all the tested derivatives against the MCF‐7 cancer cells. Additionally, the furfural Schiff base compound was more potent than colchicine by 1.74‐fold, while benzaldehyde Schiff base compound was nearly equipotent with colchicine as standard drug. In addition to tubulin inhibition activity, enamide‐furfural Schiff base molecule caused cell cycle arrest in MCF‐7 cells at the G2/M phase (2.62‐fold more than control MCF‐7) and induced apoptotic death (48.97‐fold compared to untreated MCF‐7 control) as indicated by FACS analysis. Furthermore, apoptotic studies conducted by enamide‐furfural Schiff base derivative were accomplished by downregulation of mitochondrial membrane potential by 1.56‐fold relative to control untreated cells.

AbstractBackgroundProgressive retinal atrophy (PRA) is a group of canine inherited retinal disorders affecting up to 100 breeds. Genetic tests are available. The aim of this study was to retrospectively evaluate the genetic variants associated with PRA among dogs residing in Italy.MethodsGenetic data of 20 variants associated with different forms of PRA were collected through DNA tests over a 10‐year period for several dog breeds in the Italian canine population. Allelic and genotypic frequencies were calculated.ResultsA total of 1467 DNA tests were conducted for 1180 dogs. Progressive rod‐cone degeneration (PRCD) was the most tested form of PRA, with 58.15% (n = 853) of the DNA tests. Among the widespread breeds in Italy, Labrador retrievers and toy poodles showed a prevalence of heterozygous carriers higher than 15%. Among the others, 175 DNA tests for golden retrievers (GR) showed a prevalence of heterozygous carriers of 13.04% (n = 12) for GR‐PRA1 and 8.43% (n = 7) for GR‐PRA2. The zwergschnauzer breed was tested for the type B and/or the type B1 forms of PRA with 25.32% (n = 20) heterozygous carriers and 0%, respectively.ConclusionThe study offers an overview of the prevalence of PRCD and other PRA forms within some of the most popular breeds in Italy.
Holographic thermal correlators for hyperbolic CFTs

Published: November 2023

Abstract
We use holography to compute the exact form of retarded Green’s functions for a scalar operator with conformal dimension ∆ in a thermal CFT and in its related counterpart with chemical potential in R1 × H3. In our analysis, we recast the wave equation of a scalar field in the normal form of Heun’s equation in the dual gravity theories described by the AdS hyperbolic blackhole and its charged version. Heun’s equation is identified to the semiclassical limit of the BPZ equation for a five-point correlator with one degenerate field insertion in the Liouville theory on the Riemann sphere. The crossing symmetry of conformal block in the Liouville theory eventually gives rise to a set of connection formulas among the solutions of Heun’s equation evaluated at different regular singularities. We use the connection formula to reproduce the leading order behaviors of the scalar field near the horizon as well as near the boundary and achieve the exact form of the retarded thermal Green’s function. We show a recipe to obtain the exact retarded Green’s function for a thermal CFT dual to AdS blackbrane from a high-temperature limit accompanied by a complex mapping on AdS hyperbolic blackhole. Moreover, we show the retarded Green’s function for the boundary CFT of Rindler AdS spacetime admits a free integer parameter.
Meson spectrum of SU(2) QCD1+1 with quarks in Large representations

Published: November 2023

Abstract
We consider SU(2) quantum chromodynamics in 1 + 1 dimensions with a single quark in the spin J representation of the gauge group and study the theory in the large J limit where the gauge coupling g2 → 0 and J → ∞ with λ = g2J2 fixed. We work with a Dirac spinor field for arbitrary J, and with a Majorana spinor for integer J since the integer spin representations of SU(2) are real, and analyze the two cases separately.The theory is reformulated in terms of global colour non-singlet fermion bilocal operators which satisfy a W∞ × U(2J + 1) algebra. In the large J limit, the dynamics of the bilocal fields is captured by fluctuations along a particular coadjoint orbit of the W∞ algebra. We show that the global colour-singlet sector of the bilocal field fluctuations satisfy the same integral equation for meson wavefunctions that appears in the ’t Hooft model. For Majorana spinors in the integer spin J representation, the Majorana condition projects out half of the meson spectrum, as a result of which the linear spacing of the asymptotic meson spectrum for Majorana fermions is double that of Dirac fermions. The Majorana condition also projects out the zero mass bound state that is present for the Dirac quark at zero quark mass.We also consider the formulation of the model in terms of local charge densities and compute the quark spectral function in the large J limit: we see evidence for the absence of a pole in the quark propagator.

AbstractPopulation structure and phylogeography of the loggerhead sea turtle (Caretta caretta) have so far been assessed mainly by mitochondrial DNA (mtDNA) single-gene sequencing studies. However, phylogenetic relationships amongst matrilines, genetic characterisation of rookeries and mixed-stock analyses have suffered from the limited resolution obtained by comparison of relatively short sequences such as from the mtDNA control region. Whole mitogenome sequencing can significantly improve population genetics, particularly in marine organisms showing female natal philopatry. Despite mitogenomics becoming increasingly common in biodiversity monitoring and conservation, only a few complete mitogenomes are available for C. caretta. In this study, we sequenced the complete mtDNA of 61 loggerhead turtles sampled between 2008 and 2021 along the Italian coastline and central Mediterranean Sea. We assigned complete mtDNA haplotypes to dead embryos and bycatch samples, and introduced a first nomenclature for loggerhead mitogenomes. Analysis of mtDNA diversity, Maximum Parsimony and Bayesian phylogenetic reconstruction allowed improved resolution of lineages with respect to studies reporting on partial mtDNA control region sequence comparisons, and we were able to further inform previous analyses on loggerhead ancestry based on control region haplogroups. Overall, whole mitogenome analysis has potential for considerable improvement of evolutionary history and phylogeographic investigations as well as mixed-stock surveys of loggerhead turtles.
Does third molar agenesis influence the second lower molar mineralization?
Authors: Ferreira C. , Caldas I. M. 
Published: November 2023

AbstractDifferent studies have established that the mineralization stages of the second mandibular molar can be used in forensic age estimation. Nowadays, the estimate’s accuracy is an ethical concern, producing as few false positives (individuals incorrectly classified as older than a determined threshold) and false negatives (individuals incorrectly classified as younger than a determined threshold) as possible. Some have hypothesized that changes in teeth number may influence tooth mineralization, altering the age estimate process. This paper analyzes whether third molar agenesis affects the second mandibular molar mineralization time frame. To do so, 355 orthopantomograms were evaluated for third molar agenesis, and the second mandibular molar mineralization stage was assessed using the Demirjian stages. Student’s t-test was used to compare the difference in the mean age at which the various stages of 37 mineralization were reached in the groups with and without third molar agenesis. The level of statistical significance was set at 5%. The results pointed to a delay in second mandibular molar mineralization in the case of agenesis, suggesting the need to consider this when estimating age using dental techniques.
Leptomeningeal spread in high-grade gliomas: Is surgery or adjuvant therapy after leptomeningeal spread associated with survival benefit?
Authors: Zhong Shuai , Fu Xiaojun , Wu Chenxing , Liu Rui , Li Shouwei 
Published: November 2023

Abstract
Purpose
This study aimed to identify prognostic factors associated with survival in patients with high-grade glioma (HGG) after leptomeningeal spread (LMS) and to clarify the behavior and treatment response.

Methods
This retrospective study included 114 patients with HGGs diagnosed with LMS from August 1, 2014, to July 30, 2021, at our institution. Clinical, radiological, pathological, and outcome data were collected. Univariable and multivariable Cox regression were used for overall survival (OS) and post-LMS survival (PLS) analysis.

Results
The median OS was 17.0 months and the median PLS was 6.0 months. Gross total resection (GTR) after LMS diagnosis and pathology grade III were statistically significantly associated with longer OS in all patients. GTR after LMS diagnosis and nodular LMS were independent favorable prognostic factors on PLS. Non-adjuvant therapy after LMS diagnosis was associated with shorter OS and PLS. In glioblastoma (GBM) subgroup analysis, GTR after LMS diagnosis and secondary LMS were independent favorable prognostic factors on OS. Karnofsky Performance Status (KPS) of ≥80 at LMS diagnosis, chemotherapy after LMS and intrathecal methotrexate (MTX) treatment were statistically significantly associated with longer PLS. MRI type II was a predictor of shorter PLS.

Conclusion
The treatment of patients with glioma after LMS diagnosis is very challenging and limited. Safe GTR of tumor and subsequent adjuvant therapy after LMS remains a powerful weapon to improve survival for HGG patients with LMS. Chemotherapy and Intrathecal MTX treatment are feasible treatments after LMS. The extent of tumor dissemination may affect the survival after LMS.
Estimation of quadrature errors for layer potentials evaluated near surfaces with spherical topology
Authors: Sorgentone Chiara , Tornberg Anna-Karin 
Published: November 2023

AbstractNumerical simulations with rigid particles, drops, or vesicles constitute some examples that involve 3D objects with spherical topology. When the numerical method is based on boundary integral equations, the error in using a regular quadrature rule to approximate the layer potentials that appear in the formulation will increase rapidly as the evaluation point approaches the surface and the integrand becomes sharply peaked. To determine when the accuracy becomes insufficient, and a more costly special quadrature method should be used, error estimates are needed. In this paper, we present quadrature error estimates for layer potentials evaluated near surfaces of genus 0, parametrized using a polar and an azimuthal angle, discretized by a combination of the Gauss-Legendre and the trapezoidal quadrature rules. The error estimates involve no unknown coefficients, but complex-valued roots of a specified distance function. The evaluation of the error estimates in general requires a one-dimensional local root-finding procedure, but for specific geometries, we obtain analytical results. Based on these explicit solutions, we derive simplified error estimates for layer potentials evaluated near spheres; these simple formulas depend only on the distance from the surface, the radius of the sphere, and the number of discretization points. The usefulness of these error estimates is illustrated with numerical examples.
Modeling and shadowing paraconsistent BDI agents
Authors: Dunin-Kęplicz Barbara , Szałas Andrzej 
Published: November 2023

AbstractThe Bdi model of rational agency has been studied for over three decades. Many robust multiagent systems have been developed, and a number of Bdi logics have been studied. Following this intensive development phase, the importance of integrating Bdi models with inconsistency handling and revision theory have been emphasized. There is also a demand for a tighter connection between Bdi-based implementations and Bdi logics. In this paper, we address these postulates by introducing a novel, paraconsistent logical Bdi model close to implementation, with building blocks that can be represented as Sql/rule-based databases. Importantly, tractability is achieved by reasoning as querying. This stands in a sharp contrast to the high complexity of known Bdi logics. We also extend belief shadowing, a shallow and lightweight alternative to deep and computationally demanding belief revision, to encompass agents’ motivational attitudes.
