Childfree Sterilization: A Normative Rhetorical Theory Analysis of Paradoxical Dilemmas Encountered by Childfree Patients and Providers
Authors: Hintz Elizabeth 
Published: June 2022

Abstract
Guided by normative rhetorical theory, this study utilizes thematic analysis to explore narratives about sterilization consultations posted by childfree patients and medical providers to Reddit. This study explores the multiple meanings of sterilization, the paradoxical dilemmas competing conversational purposes create, and the communicative practices, interpretive lenses, and environmental resources patients and providers employ to manage dilemmas. The analysis reveals that voluntary sterilization inheres task, relational, and identity meanings for both patients and providers, creating paradoxical dilemmas and rendering sterilization consultations additionally challenging to navigate. Patients and providers both accept and confront paradox, adopt cultural and contextual interpretive lenses to evaluate others’ talk, and rely on childfree patient and physician social networks as environmental resources to shift the context in which talk occurs. The conclusion offers theoretical implications for normative rhetorical theory and practical implications, including: illuminating features influencing interactions in which sterilization requests are made and evaluated, and underscoring the multiple meanings that constrain patients and providers during these consultations.

Published: June 2022

AbstractIn this work, high‐performance VO2 Mott memristors with the simple via‐hole structure of Pt/VO2/Pt are fabricated on flexible Kapton polymide (PI) substrate with high endurance (>104 sweep‐voltage cycles), good bending stability (>103), and low operating current (<130 µA). The electrical properties of flexible memristor are well modeled by using the 3D Poole–Frenkel emission and Newton's law of cooling considering the temperature dependence of electrical and thermal properties of VO2. As a result, a flexible artificial spiking warm receptor is achieved by using a single VO2 Mott memristor driven by a current source. And an oscillation circuit model is presented to thoroughly study the effects of the memristor electrical properties on the spiking frequency. With the stimulus temperature elevated from 20 to 40 °C, the spiking frequency of artificial spiking warm receptor first increases, then falls off rather quickly to zero at the higher temperature of 45 °C, resembling the response characteristics of biological warm receptors. Hence, the proposed flexible artificial spiking warm receptor is a promising candidate for the bio‐inspired electronic skin of spike‐based intelligence machines with neuromorphic computing.

AbstractLithium metal is considered as the most prospective electrode for next‐generation energy storage systems due to high capacity and the lowest potential. However, uncontrollable spatial growth of lithium dendrites and the crack of solid electrolyte interphase still hinder its application. Herein, Schottky defects are motivated to tune the 4f‐center electronic structures of catalysts to provide active sites to accelerate Li transport kinetics. As experimentally and theoretically confirmed, the electronic density is redistributed and affected by the Schottky defects, offering numerous active catalytic centers with stronger ion diffusion capability to guide the horizontal lithium deposition against dendrite growth. Consequently, the Li electrode with artificial electronic‐modulation layer remarkably decreases the barriers of desolvation, nucleation, and diffusion, extends the dendrite‐free plating lifespan up to 1200 h, and improves reversible Coulombic efficiency. With a simultaneous catalytic effect on the conversions of sulfur species at the cathodic side, the integrated Li–S full battery exhibits superior rate performance of 653 mA h g−1 at 5 C, high long‐life capacity retention of 81.4% at 3 C, and a high energy density of 2264 W h kg−1 based on sulfur in a pouch cell, showing the promising potential toward high‐safety and long‐cycling lithium metal batteries.

Published: June 2022

AbstractPremiseHigh‐precision data acquisition (DAQ) is essential for developing new methods in the plant sciences. Commercial high‐resolution DAQ systems are cost prohibitive, whereas the less expensive systems that are currently available lack the resolution and precision required for many physiological measurements.Methods and ResultsWe developed the software libraries, called piadcs, and hardware design for a DAQ system based on an ultra‐high‐resolution analog‐to‐digital converter and a Raspberry Pi computer. We tested the system precision with and without a thermocouple attached and found the precision with the sensor to be better than ±0.01°C and the maximum possible system resolution to be 0.4 ppm.ConclusionsThe ultra‐high‐resolution DAQ system described here is inexpensive, flexible enough to be used with many different sensors, and can be built by researchers with rudimentary electronic and computer skills. This system is most applicable in the development of new measurement techniques and the improvement of existing methods.

ObjectiveThe study of autoantibody isotypes in autoimmune diseases is useful for identifying clinically relevant endotypes. This study was undertaken to study the prevalence and clinical significance of different isotypes and IgG subclasses of anti–peptidylarginine deiminase 4 (anti‐PAD4) autoantibodies in individuals with rheumatoid arthritis (RA).MethodsIn 196 RA subjects and 64 healthy controls, anti‐PAD4 antibody types were determined using enzyme‐linked immunosorbent assay. We investigated associations between anti‐PAD4 antibodies and clinical outcomes, and relevant features were confirmed in an independent RA cohort.ResultsAnti‐PAD4 IgG1, anti‐PAD4 IgG2, anti‐PAD4 IgG3, anti‐PAD4 IgG4, anti‐PAD4 IgA, and anti‐PAD4 IgE antibodies were more frequent in RA patients than healthy controls (P < 0.001). Anti‐PAD4 IgG1, anti‐PAD4 IgG3, and anti‐PAD4 IgE were associated with distinct clinical features. Anti‐PAD4 IgG1 was predictive of progressive radiographic joint damage (odds ratio [OR] 4.88, P = 0.005), especially in RA patients without baseline joint damage (40% versus 0%, P = 0.003) or in those negative for anti–cyclic citrullinated peptide and/or rheumatoid factor (OR 32; P = 0.009). IgG1 was also associated with higher levels of C‐reactive protein (P = 0.006) and interleukin‐6 (P = 0.021). RA patients with anti‐PAD4 IgG3 had higher baseline joint damage scores (median Sharp/van der Heijde score 13 versus 7, P = 0.046), while those with anti‐PAD4 IgE had higher Disease Activity Score in 28 joints (median 4.0 versus 3.5, P = 0.025), more frequent rheumatoid nodules (31% versus 16%, P = 0.025), and more frequent interstitial lung disease (ground‐glass opacification) (24% versus 9%, P = 0.014). Anti‐PAD4 IgG1 antibody associations with joint damage were corroborated in an independent RA cohort.ConclusionAnti‐PAD4 IgG1, anti‐PAD4 IgG3, and anti‐PAD4 IgE antibodies identify discrete disease subsets in RA, suggesting that heavy chain usage drives distinct effector mechanisms of anti‐PAD4 antibodies in RA.

AbstractChemical investigation of the EtOH extract of the sponge Axinella sp. collected from the South China Sea resulted in the identification of one new pyrrololactam alkaloid, axinellamine E (2), along with four known analogs (1, 3–5). Compound 1 was initially separated as enantiomers and was further separated to be optically pure compounds (1 a and 1 b) by a chiral column. The planar structure of compound 2 was determined mainly by 1D‐, 2D‐NMR, and HR‐ESI‐MS data analyses. Absolute configurations of 1 a and 1 b was defined by calculated ECD spectra method. All of the compounds were evaluated for their anti‐inflammatory activities against nitric oxide production in lipopolysaccharide‐induced RAW 264.7 cells among which compound 1 showed weak activity at 40 μg/mL. Plausible biosynthetic pathways corresponding to aldisine analogs of 1, 2, 4, and 5 were also discussed.

Published: June 2022

AbstractBackgroundLeft atrial appendage (LAA) closure (LAAC) can safely and effectively prevent stroke events caused by atrial fibrillation. However, the structure of the LAA is highly variable among individuals, and the optimal method for obtaining measurements remains unknown.HypothesisWe aimed to study the accuracy of left atrial computed tomography angiography (CTA), three‐dimensional (3D) reconstruction using CTA, two‐dimensional transesophageal echocardiography (2D‐TEE), and digital subtraction angiography (DSA) for measuring the diameter of the LAA and compare their value for selecting occluder size.MethodsWe retrospectively evaluated data for 148 patients with nonvalvular atrial fibrillation who underwent successful LAAC. CTA and 2D‐TEE of the left atrium and pulmonary vein were performed before LAAC. We performed 3D reconstruction of the left atrium and LAA using Mimics and 3‐matics software. DSA of the LAA was performed during surgery.ResultsValues measured via CTA 3D reconstruction were significantly higher than those measured using other methods. DSA‐measured values were significantly lower than those measured via CTA and CTA 3D reconstruction. Occluder size was positively correlated with LAA orifice diameter. The differences between occluder size and DSA, 2D‐TEE, CTA, CTA 3D reconstruction measurements were 4.96 ± 2.58, 4.64 ± 2.50, 4.04 ± 1.37, and 2.92 ± 1.38 mm, respectively. Intraclass correlation coefficients for these methods were −.067, .006, .241, and .519, respectively.ConclusionCTA 3D reconstruction provides the best correlation and consistency between the measured LAA orifice diameter and occluder size. Adding 2–4 mm to the maximum LAA orifice diameter based on 3D‐CTA may aid in selecting the appropriate WATCHMAN device.

AbstractBackgroundAtherosclerosis‐related adverse events are commonly observed even in conditions with low cardiovascular (CV) risk. Longitudinal data regarding the association of normal systolic blood pressure maintenance (SBPmaintain) with coronary plaque volume changes (PVC) has been limited in adults without traditional CV disease.HypothesisNormal SBPmaintain is important to attenuate coronary atherosclerosis progression in adults without baseline CV disease.MethodsWe analyzed 95 adults (56.7 ± 8.5 years; 40.0% men) without baseline CV disease who underwent serial coronary computed tomographic angiography with mean 3.5 years of follow‐up. All participants were divided into two groups of normal SBPmaintain (follow‐up SBP < 120 mm Hg) and ≥elevated SBPmaintain (follow‐up SBP ≥ 120 mm Hg). Annualized PVC was defined as PVC divided by the interscan period.ResultsCompared to participants with normal SBPmaintain, those with ≥elevated SBPmaintain had higher annualized total PVC (mm3/year) (0.0 [0.0–2.2] vs. 4.1 [0.0–13.0]; p < .001). Baseline total plaque volume (β = .10) and the levels of SBPmaintain (β = .23) and follow‐up high‐density lipoprotein cholesterol (β = −0.28) were associated with annualized total PVC (all p < .05). The optimal cutoff of SBPmaintain for predicting plaque progression was 118.5 mm Hg (sensitivity: 78.2%, specificity: 62.5%; area under curve: 0.700; 95% confidence interval [CI]: 0.59–0.81; p < .05). SBPmaintain ≥ 118.5 mm Hg (odds ratio [OR]: 4.03; 95% CI: 1.51–10.75) and baseline total plaque volume (OR: 1.03; 95% CI: 1.01–1.06) independently influenced coronary plaque progression (all p < .05).ConclusionNormal SBPmaintain is substantial to attenuate coronary atherosclerosis progression in conditions without established CV disease.
Abnormal behavior detection of stationary objects in surveillance videos with visualization and classification
Authors: Sharma Preeti , Gangadharappa Mandlem 
Published: June 2022

SUMMARYAnomaly detection in video systems has been popular over several years. It is still challenging to detect anomalies in a static object. To manage this objective, we focus on changes in the position of a stationary object in videos. In a normal scenario, the pixel values of the static object are fixed while in abnormal motion the fixed values change. We introduce a new concept to determine anomalies based on manual annotations in each video frame, only over a part of a static object in a frame such that it can be taken as a reference for the whole. Through color channel splitting we determine mask image, from which handcrafted features such as scratch area, perimeter, equivalent diameter and density are calculated. In the next step, we analyze frame‐wise changes in feature values using a linear regression model, feature values are constant when the object remains stationary while there is a rise or fall in values when an object changes location. We classify feature values through anomaly scores and thresholds. In this model, we are evaluating our proposed framework on 12 real‐time video datasets. Results are compared with existing techniques which are outperforming in terms of accuracy, mean square error and area under the curve.
Microsolvated Ion‐Molecule SN2 Reactions with Dual Nucleophiles Induced by Solvent Molecules
Authors: Wu Xiangyu , Zhao Chongyang , Xie Jing 
Published: June 2022

AbstractSingly‐hydrated HOO− anion was found to induce alternative nucleophile HO− via proton transfer from water molecule when reacting with CH3Cl. To investigate the generality of this effect, the competition between the solvent‐induced HO−−SN2 pathway and the normal HOO−−SN2 pathway is studied for the microsolvated HOO−(H2O)n=1,2,3+CH3X (X=F, Cl, Br, I) reaction by quantum chemistry calculations. Incremental hydration increases the barrier heights of both pathways and enlarges the barrier difference between them, which favors the HOO−−SN2 pathway. Interestingly, the barrier difference is insensitive to the leaving group. Calculations show that the water induced HO−−SN2 pathway is highly suppressed when the degree of hydration increases beyond two. The differential barrier under incremental hydration can be explained by solvent molecules stabilizing the HOMO level of HO−(HOOH)(H2O)n‐1 nucleophile more than that of the HOO−(H2O)n nucleophile. Comparison between the HO−‐ and HOO−‐nucleophiles suggests that α‐effect exists. Activation strain analysis attributes the barrier differences to stronger TS distortion of the HO−−SN2 pathway than that of the HOO−−SN2 pathway.
