BackgroundIt is challenging to detect small nontransmural infarcts visually or automatically. As it is important to detect myocardial infarction (MI) at early stages, we tested the hypothesis that small nontransmural MI can be detected using speckle tracking echocardiography (STE) at the acute stage.MethodsMinimal nontransmural infarcts were induced in 18 rats by causing recurrent ischemia–reperfusion of the left anterior descending (LAD) coronary artery, followed by a 30‐min ligation and by reperfusion. A week later, the scar size was measured by histological analysis. Each rat underwent three echocardiography measurements: at baseline, 1 day post‐MI, and 1 week post‐MI. To measure the peak circumferential strain (CS), peak systolic CS, radial strain (RS), and time‐to‐peak (TTP) of the CS, short‐axis view of the apex was analyzed by a STE program. The TTP was normalized by the duration of the heart cycle to create percent change of heart cycle.ResultsHistological analysis after 1 week showed scar size of 4±6% at the anterior wall. At 24 h post‐MI, the peak CS, peak systolic CS, and RS were reduced compared to baseline at the anterior wall due to the MI, and at the adjacent segments—the anterior septum and lateral wall, due to stunning (P<.05). However, only the anterior wall, the genuine damaged segment, showed prolonged TTP vs baseline (baseline 36%, 24 h 48%, P<.05).ConclusionThe TTP of the CS can distinguish between regions adjacent to MI (stunned or tethered) and MI, even in small nontransmural infarcts.

O artigo consiste em um relato de experiência docente, cujos enfrentamentos didáticos, tão comuns ao universo daqueles que se dedicam à educação, são (re)inventados no encontro entre uma proposta curricular singular para o ensino de História e as dinâmicas próprias de uma sala de aula. A educação para a “sensibilidade histórica”, tal como nos propõe Marc Bloch, torna-se o fio condutor capaz de conferir ao docente outra forma de olhar para a aprendizagem de seus estudantes e, a partir dessas demandas, construir repertórios didáticos significativos. Nesse ínterim, podem-se perceber as escolhas e estratégias adotadas por uma professora que se coloca em movimento.
Deposition of Solid Impurity During Washing of Softented Cotton in Function of the Mixtures of Surfactants
Authors: Carrión-Fité F. J. 
Published: July 2016

AbstractThe objective of this paper is to measure the deposition of solid impurity on finished cotton fabric treated with DMDHEU resin during washing cycles of cotton fabric treated with different softeners. Fabrics will be softened with the conventional esterquat and with aminosilicone products having different molecular weights and mixtures of both. The anionic surfactant sodium dodecyl benzene sulphonate and non-ionic surfactant ethoxylated fatty alcohol were used. Both separately and in different proportions during the deposition trials were used. In general, the deposition values decrease on increasing the quantity of non-ionic surfactant in the mixture and with the finished cotton fabric increase this one after the application of the softeners tested alone and with their mixtures.

The unrecognised potential of large N – Strengths and limitations of the German Microcensus exemplified by fertility research Due to a large number of cases (688.931 persons in 2012) the German Microcensus has a huge potential for analyses in demography and family sociology. Content is further improved by the new voluntary question on biological children of women. This paper aims to systematically assess the methodological background as well as limitations and potentials of the Microcensus using the example of fertility data. The analyses of nonresponse show that the way of questioning has a strong impact. The related bias could, however, be reduced by imputations. The main limitations are the cross-sectional design and missing data on the children of men and internal migration. The potential of the high case numbers of the Microcensus is systematically discussed by analyzing confidence intervals: It allows for in-dept differentiations for analyzing social structure, birth parities and time patterns. Finally, we discuss three research designs which are able to use this potential: Dendrogram analyses allow group differentiations for up to five levels and thus reveal detailed patterns of childlessness. Parity patterns by cohorts illustrate differences by occupational education. Third, the age-specific analyses of first births among several cohorts allow for identifying trends of recuperation which differ considerable between educational groups.
Zusammenfassung
Aufgrund der hohen Fallzahlen (688.931 Personen in 2012) ist das Potenzial des Mikrozensus (MZ) für demografische und familiensoziologische Analysen groß, zudem inhaltlich durch die Erhebung der Geburten von Frauen noch gestiegen. Der Beitrag hat zum Ziel, methodische Hintergründe, Limitierungen und Potenziale des MZ am Beispiel von Fertilität systematisch aufzuzeigen. Die Analyse von Antwortverweigerungen zeigt, dass die Art der Befragung einen starken Einfluss hat, deren Verzerrungen durch Imputationen deutlich reduziert werden konnten. Die Limitierungen sind v.a. das Querschnittsdesign sowie die fehlenden Daten zur Kinderzahl von Männern und zur Binnenmobilität. Die hohen Fallzahlen des MZ ermöglichen tiefenscharfe Differenzierungen bezüglich Sozialstruktur, Paritäten und Zeitverläufe, was anhand von Konfidenzintervallen diskutiert wird. Drei Forschungsdesigns, die die Analysepotenziale nutzen, werden vorgestellt: Dendrogrammanalysen ermöglichen gruppenspezifische Differenzierungen nach fünf Ebenen und zeigen so ein detailliertes Muster der Kinderlosigkeit. Der Verlauf von Paritätsmustern im Kohortenvergleich verdeutlicht die je nach beruflicher Bildung unterschiedlichen Verläufe. Die Analysen zur altersspezifischen Häufigkeit von Erstgeburten ermöglichen, Trends von nachholenden Geburten für verschiedene Bildungsgruppen zu identifizieren.

ImportanceWhile direct penicillin challenges might support the expansion of penicillin allergy delabeling efforts, the perceived risk of reactions remains a key barrier.ObjectiveTo evaluate the frequency of reactions to direct penicillin challenges in individuals with penicillin allergy labels and to identify factors associated with such reactions.Data SourcesThree electronic databases were searched (MEDLINE, Web of Science, and Scopus) from inception to July 19, 2023, for primary studies assessing patients undergoing direct penicillin challenges. Articles were included regardless of publication year, language, status, or definition of allergy risk.Study SelectionTwo reviewers independently selected original studies reporting the frequency of immunologically mediated reactions following a direct penicillin challenge in patients reporting a penicillin allergy.Data Extraction and SynthesisTwo reviewers independently extracted data and independently assessed the quality of each primary study using a risk-of-bias tool for prevalence studies.Main Outcomes and MeasuresThe primary outcome was the frequency of reactions to direct penicillin challenges as calculated using random-effects bayesian meta-analysis of proportions. Secondary outcomes included risk factors for reactions and the frequency of severe reactions.ResultsA total of 56 primary studies involving 9225 participants were included. Among participants, 438 experienced reactions to direct penicillin challenges without prior testing, corresponding to an overall meta-analytic frequency of 3.5% (95% credible interval [CrI], 2.5%-4.6%). Meta-regression analyses revealed that studies performed in North America had lower rates of reaction to direct challenges (odds ratio [OR], 0.36; 95% CrI, 0.20-0.61), while studies performed in children (OR, 3.37; 95% CrI, 1.98-5.98), in outpatients (OR, 2.19; 95% CrI, 1.08-4.75), and with a graded (OR, 3.24; 95% CrI, 1.50-7.06) or prolonged (OR, 5.45; 95% CrI, 2.38-13.28) challenge had higher rates of reaction. Only 5 severe reactions (3 anaphylaxis, 1 fever with rash, and 1 acute kidney injury) were reported, none of which were fatal.Conclusions and RelevanceThis systematic review and meta-analysis found that reactions to direct penicillin challenges are infrequent, with rates comparable to indirect challenges after allergy testing. These findings suggest that direct challenges are safe for incorporation into penicillin allergy evaluation efforts across age groups and clinical settings.
Design of Experiments

Published: September 2024

Abstract
The statistical design of experiments (DOEs) is an essential ingredient of successful product development and improvement. DOE provides an efficient and scientific approach to obtaining meaningful information. In contrast to traditional one‐factor‐at‐a‐time (OFAT) experimentation, DOE changes factors together, permitting evaluation of interactions. Standard texts give details about the construction of specific experiment designs, such as incomplete block, full and fractional factorial, response surface designs, and mixture designs; and the analysis of the resulting data. This chapter focuses on the fundamental elements of DOE: defining the purpose and scope of the experiment, differentiating between alternative types of experimental variables, understanding the underlying environment and constraints, and conducting stage‐wise experimentation. It covers the basic elements of the design and analysis of experiments based on a multifactor approach that is far more effective and efficient than OFAT for chemical research and development.

Published: September 2024

AbstractIn Europe, the gray wolf and Eurasian lynx populations are recovering after various levels of persecution. The two species differ in their social structure and spatial patterns of aggregation. Using model selection, we investigated the consistency of the available time series data on local wolf and lynx sub‐populations with a number of single‐species population growth models that pertain to two types of intraspecific competition, namely, scramble (SC) and contest competition (CC), and reflect random (R) or aggregated (A) distribution of individuals. The applied models of population growth—the Ricker (SCR), Skellam (CCR), Hassell (SCA), and Beverton–Holt (CCA) models—were all parameterized in terms of intrinsic growth rate and carrying capacity with unified definitions. The projected carrying capacity was allowed to show a temporal trend, which was justified by an observed increase in prey abundance in recent decades. For both species, the models pertaining to contest competition outperformed the scramble competition models, and the Beverton–Holt model had the greatest weight. However, for the lynx, the difference of performance between the scramble and contest competition models was considerably smaller than that for the wolves. In most of the models, when it was meaningful, an optional time lag operator was added to account for a delay in individual maturity and reproduction. However, the models with a time lag had a worse fit than the models without it. This study promotes the application of population models that reflect intraspecific competition for modeling population dynamics in a single‐ or multi‐species framework.

Abstract
This article is to give a brief introduction on how to utilize wavefunction‐based multireference methods to predict electronic structures, spectroscopic properties, and reactivities of transition metal complexes. To this end, we choose a series of high‐valent iron complexes as examples. Specifically, we first focus on how to choose an appropriate active space, then delineate how to extract electronic‐structure information from highly correlated multireference wavefunctions and, finally, elaborate how to establish the correlation of electronic structures with spectroscopic parameters and reactivities.

Published: September 2024

ABSTRACTThis article considers the trajectory tracking problem of automated guided vehicles with unknown‐but‐bounded noises and proposes a set‐membership filtering (SMF) based model predictive control strategy. A 2‐DOF vehicle model is first established with considering the unknown‐but‐bounded process and measurement noises. Then, a trajectory tracking control scheme is proposed which consists of two parts, that is, a set‐membership observer and a model predictive controller. The proposed set‐membership observer is able to deal with the unknown‐but‐bounded noises and obtain the state estimation ellipsoid for the considered automated guided vehicle. Further, the designed model predictive controller utilizes the estimated ellipsoid to compute the control sequence. Finally, simulation results demonstrate the effectiveness and superiority of the proposed method.

AbstractOn‐skin electronics rely on flexible power sources for stable operation and comfortable wearing. However, the current materials and device designs of on‐skin batteries for human‐interface electronic systems suffer from inadequate adhesion and impermeability. In this work, a general design of a bioadhesive and breathable on‐skin flexible metal‐air battery is presented. By laterally loading a conducting polymer‐based cathode and a zinc anode onto a biocompatible silk fibroin ionic hydrogel electrolyte film, the battery exhibits good epidermal adhesions (shear strength exceeds 20 kPa and interface toughness exceeds 150 J m−2) and excellent sweat breathability (3 times greater than commercial 3 M breathable dressing). A singular battery can generate an open circuit voltage of up to 1.4 V and a power density of 72 µW cm−2. It shows stable adhesion to the skin for five days, while simultaneously preserving epidermal respiratory function and facilitating natural skin movement. On‐skin integration of the battery array can be easily conducted to increase the electrical output. This battery design enhances the usability, comfort, and safety of wearable electronics, enabling new applications in healthcare, fitness tracking, and beyond.

Published: September 2024

AbstractLow‐cost direct air capture (DAC) systems require efficient gas–solid contactors. These contactors provide rapid rates of heat and mass transport with minimal pressure drops. Triply periodic minimal surfaces (TPMS) are a class of geometries that are shown to have heat transfer properties that exceed those of other geometries, and these benefits are expected to manifest in mass transfer as well due to the analogies between heat and mass transfer. However, creating TPMS contactors is difficult using conventional manufacturing techniques such as injection molding. Non‐solvent‐induced phase separation (NIPS) of a polymeric ink containing the adsorbent is one way to construct adsorption contactors with excellent mass transport rates, but contactors have to date only been fabricated in simple geometries (e.g., films, fibers). This study demonstrates that NIPS of polymeric inks occurs within a simultaneously‐dissolving, water‐soluble, 3D‐printed template. This templated phase inversion (TPI) technique can create seemingly unlimited macroscopic architectures, including TPMS contactors, using a variety of potential DAC adsorbents, including zeolite, silica, activated carbon, and metal–organic frameworks. SEM, micro‐computed tomography, and nitrogen adsorption experiments reveal the microscopic pore structures and macroscopic geometries of the resulting sorbent contactors. TPMS DAC contactors with poly(ethyleneimine)/silica adsorbents are shown to have CO2 capture performances that rival or exceed other contactor geometries.

Published: September 2024

AbstractThe emergence of 2D van der Waals (vdW) materials, owing to highly tunable electrical conductivity, remarkably free stackability, and excellent compatibility for heterojunction integration, has provided abundant research diversity of artificial synapses. Here, an innovative 2D vdW heterosynaptic memtransistor (vdW‐HT) synapse is proposed with a ferroelectric CuInP2S6 inserted layer. Neuromorphic synaptic weight change of the vdW‐HT synapse in this work are modulated by the synergistic effects of interlayer coupling and ferroelectric polarization reversal. It is the first time to evaluate the required initial energy consumption of ferroelectric vdW‐HT synapses with matrixed biomimetic characteristics of “Learning–Forgetting–Re‐learning–Memorizing.” The required initial energy consumption is only ≈3.06 pJ, which provided supporting evidence to indicate the promising potential of vdW‐HT synapses in exploring neuromorphic applications. A vdW‐HT computing system with artificial recognition capability for intelligent automobiles is established and demonstrated outstanding recognition abilities for multiple targets in various environments. The highest recognition accuracy for pedestrians is 98%. In addition, the excellent recognition property is integrated with a robotic arm, successfully achieving high‐precision grasping behavior and designated position transmission for identified targets. These results provide promising strategies for the integrated development of emerging neuromorphic electronics and industrial applications.

Published: September 2024

AbstractSelf‐powered visualized sensor with skin‐like functionality is highly anticipated for practical application in health monitoring, human‐machine interaction, and robotics. However, the existing methods are disadvantaged by their poor performance in sensitivity and spatial fidelity due to the low pixel density, brightness, or conformability. Herein, a novel self‐powered skin‐inspired visualized sensor (SP‐SIVS) is developed by means of triboelectrification‐induced electroluminescence (TIEL) technique. By integrating surface and bulk charge generation with a high‐voltage corona charging treatment, a significant improvement is achieved in the brightness (by 10‐fold) and spatial resolution (100 µm) of the SP‐SIVS. Meanwhile, Young's modulus (94 kPa) is maintained at a level comparable to human skin, with tensile strength and elongation exceeding 1000 kPa and 1000%, respectively. Furthermore, SP‐SIVS is verified as applicable to serve such purposes as wearable motion detection, fingerprint morphology imaging, and information interaction. This work contributes an innovative framework to the development of SP‐SIVS with high‐brightness, high‐resolution, and sustainability, laying a foundation for its popularization as a novel interactive medium required for advanced photonic applications.

Published: September 2024

AbstractHerein, the construction of sp‐C–P‐Cu bridged graphdiyne (GDY)‐copper phosphides (CuxP) heterointerface structure is described by controlled growth of GDY on the surface of CuxP for efficient hydrogen evolution reaction (HER). The experimental results demonstrate that the newly formed sp‐C─P bonds at the interfaces between GDY and CuxP have the dual roles of promoting faster charge transfer and producing large numbers of new intrinsic active sites, which facilitates the activation and dissociation of H2O to produce H2 and greatly enhanced the intrinsic electrocatalytic activity. As expected, the as‐synthesized electrocatalyst exhibits excellent activity for hydrogen evolution reaction (HER) with overpotentials of 44 mV at 10 mA cm−2, which is smaller than that of pure CuxP and Cu foam electrocatalysts. These results correlate interface structure and HER activity and provide new insights into the design and synthesis of high‐performance electrocatalysts.
