The flexibility paradox and spatial‐temporal dimensions of COVID‐19 remote work adaptation among dual‐earner mothers and fathers
Authors: Parry Ashley 
Published: April 2024

AbstractThere is an increased blurring of work and home life in contemporary society due to access to technology and the mass expansion of remote work during the COVID‐19 pandemic. Flexible working arrangements like remote work can lead to men self‐exploiting themselves in the workplace and women self‐exploiting themselves in the domestic sphere in the context of a work‐centric society that is reliant upon passion at work and traditional gender norms. This study extends Chung's ideas on gendered patterns in the flexibility paradox by examining spatial‐temporal dimensions of COVID‐19 remote work adaptation among an extreme sample: dual‐earner parents with young children. Semi‐structured interviews were conducted on Zoom with 20 mothers and 17 fathers working from home in the U.S. with children ages 5 and under between the summer of 2020 and the spring of 2021. Findings indicate that fathers' work is prioritized in spatio‐temporal terms whereas mothers' work is fragmented and dispersed. Gendered patterns in the flexibility paradox and labor shouldered by mothers as primary caregivers are considered as potential theoretical explanations for the privileging of fathers' workspace and work time.

AbstractBackgroundTreatment of Helicobacter pylori gastric infection is complex and associated with increased rates of therapeutic failure. This research aimed to characterize the H. pylori infection status, strain resistance to antimicrobial agents, and the predominant lesion pattern in the gastroduodenal mucosa of patients with clinical suspicion of refractoriness to first‐ and second‐line treatment who were diagnosed and treated in a health center in Guayaquil, Ecuador.MethodsA total of 374 patients with upper gastrointestinal symptoms and H. pylori infection were preselected and prescribed one of three triple therapy regimens for primary infection, as judged by the treating physician. Subsequently, 121 patients who returned to the follow‐up visit with persistent symptoms after treatment were studied.ResultsAll patients had H. pylori infection. Histopathological examination diagnosed chronic active gastritis in 91.7% of cases; premalignant lesions were observed in 15.8%. The three triple therapy schemes applied showed suboptimal efficacy (between 47.6% and 77.2%), with the best performance corresponding to the scheme consisting of a proton pump inhibitor + amoxicillin + levofloxacin. Bacterial strains showed very high phenotypic resistance to all five antimicrobials tested: clarithromycin, 82.9%; metronidazole, 69.7%; amoxicillin and levofloxacin, almost 50%; tetracycline, 38.2%. Concurrent resistance to clarithromycin–amoxicillin was 43.4%, to tetracycline–metronidazole 30.3%, to amoxicillin–levofloxacin 27.6%, and to clarithromycin–metronidazole 59.2%.ConclusionsIn vitro testing revealed resistance to all five antibiotics, indicating that H. pylori exhibited resistance phenotypes to these antibiotics. Consequently, the effectiveness of triple treatments may be compromised, and further studies are needed to assess refractoriness in quadruple and concomitant therapies.

AbstractZircon U–Pb dates for felsic and intermediate to mafic dikes intruding into the Ryoke granitoids and metamorphic rocks at selected outcrops in the Takamiyama area of the eastern Kii Peninsula, southwest Japan, were determined along with their geology and petrography to reveal the history of Cretaceous magmatism. At each outcrop, the felsic and intermediate to mafic dikes exhibit specific structures that are indicative of magma intermingling and have coeval intrusion ages of ca. 81–77 Ma. Our zircon U–Pb data complement previously published data, suggesting that the mafic magmatism continued intermittently from 83 to 76 Ma in the Takamiyama area and that magmatism migrated eastward within the Ryoke Belt. A comparison of intrusion ages between a dike and a host Ryoke granitoid at one outcrop indicates that the host rock experienced ductile deformation at ~88 to ~83 Ma. Judging from the small number of zircons and the concordant date distributions, we didn't recognize the evidence suggesting the partial melting of the host rocks, as Nakajima et al. (Journal of the Geological Society of Japan, 2021, 127, 69–78) reported.

Published: April 2024

AbstractEchocardiographic guidance in left atrial appendage (LAA) closure procedures is increasingly recognized for its potential to enhance patient outcomes in atrial fibrillation (AF). This retrospective study assesses its impact on hospital stay duration, readmission rates and surgical site wound complications in 200 AF patients. Divided equally into an echocardiographically guided group (Group E) and a non‐guided group (Group N), the analysis focused on detailed patient data encompassing hospital stay, 30‐day readmission and wound complications. Findings revealed that Group E experienced a significantly shorter average hospital stay of 3.5 days, compared with 6.5 days in Group N, along with a lower 30‐day readmission rate (5% vs. 18% in Group N). Furthermore, Group E showed a considerable reduction in surgical site wound complications, such as infections and hematomas. The study concludes that echocardiographic guidance in LAA closure procedures markedly improves postoperative wound outcomes, underscoring its potential as a standard practice in cardiac surgeries for AF patients. This approach not only optimizes patient safety and postoperative recovery but also enhances healthcare resource utilization.

Published: April 2024

AbstractA widely used dough viscosity model in food extrusion was adopted and employed for the analysis and prediction of extruded aquafeed physical quality parameters. The data for the analysis were collected from previously published articles. The analysis was based on the assumption that pellet physical quality parameters, such as bulk density, oil adsorption, hardness, and durability, are correlated to the dough viscosity property changes in the extrusion process. The physical qualities of feed were modeled using the modified viscosity model. The model was evaluated using the data collected from experiments conducted in three different pilot extrusion systems. The results showed that the new model has the capability to predict the physical quality parameters of extruded aquafeed pellets in the three studied scenarios. The absolute average deviations of the model regression for the pellet qualities were 8.5% for hardness, 4.8% for bulk density, 6.5% for oil adsorption, 15.7% for Holmen durability, and 0.7% for pellet diameter. The new model can correlate the physical qualities of aquafeed pellets across different recipes, extruder configurations, and systems.Practical ApplicationsFood or aquatic feed extrusion process operation heavily depends on the operator's experiences and is still a black‐box process. In this study, a dough viscosity model was applied to explain the relationship between extrusion variables and extruded pellet physical qualities. The new model can be used for a quantitative description of a feed formulation extrusion process and feed pellet quality optimization.

AbstractDuring continental collision, crustal rocks are buried, deformed, transformed and exhumed. The rates, timescales and tectonic implications of these processes are constrained through the sequence and conditions of metamorphic reactions in major and accessory phases. Petrographic, isotopic and elemental data from metabasite samples in NW Bhutan, eastern Himalaya, suggest initial equilibration under high‐pressure (plagioclase‐absent and rutile‐present) conditions, followed by decompression to lower pressure conditions at high‐temperatures that stabilized plagioclase, orthopyroxene and ilmenite. Field observations and chemical indicators suggest equilibration under the lower pressure conditions is likely linked to the infiltration of melt from the host metasedimentary rocks. The metabasites preserve two metamorphic growth stages of chemically‐and petrographically distinct allanite that temporally overlap two stages of zircon growth. Allanite cores and zircon mantles grew at c. 19 ± 2 and 17–15.5 Ma respectively, linked texturally and chemically to the high‐pressure evolution. Symplectitic rims on embayed allanite cores, wholly symplectized Aln–Ilm and Aln–Cpx grains, and high U zircon rims grew at c. 15.5–14.5 Ma, linked chemically to the presence of melt and lower pressure, high‐temperature conditions. A single garnet Lu–Hf date is interpreted as geologically meaningless, with the bulk rock composition modified by melt infiltration after garnet formation. The open system evolution of these rocks precludes precise determination of the reactive bulk composition during metamorphic evolution and thus absolute conditions, especially during the early high‐pressure evolution. Despite these limitations, we show that combined geochemical and petrographic datasets are still able to provide insights into the rates and timescales of deep orogenic processes. The data suggest a younger and shallower evolution for the NW Bhutan metabasites compared to similar rocks in the central and eastern Himalayas.
Does the pancreas of gekkotans differentiate similarly? Developmental structural and 3D studies of the mourning gecko (Lepidodactylus lugubris) and the leopard gecko (Eublepharis macularius)

AbstractThis study investigated the pancreas differentiation of two species of gekkotan families—the mourning gecko Lepidodactylus lugubris (Gekkonidae) and the leopard gecko Eublepharis macularius (Eublepharidae)—based on two‐dimensional (2D) histological samples and three‐dimensional (3D) reconstructions of the position of the pancreatic buds and the surrounding organs. The results showed that at the moment of egg laying, the pancreas of L. lugubris is composed of three distinct primordia: one dorsal and two ventral. The dorsal primordium differentiates earlier than either ventral primordium. The right ventral primordium is more prominent and distinctive, starting to form earlier than the left one. Moreover, at this time, the pancreas of the leopard gecko is composed of the dorsal and right ventral primordium and the duct of the left ventral primordium. It means that the leopard gecko's left primordium is a transitional structure. These results indicate that the early development of the gekkotan pancreas is species specific. The pancreatic buds of the leopard and mourning gecko initially enter the duodenum by separate outlets, similar to the pancreas of other vertebrates. The pancreatic buds (3 of the mourning gecko and 2 of the leopard gecko) fuse quickly and form an embryonic pancreas. After that, the structure of this organ changes. After fusion, the pancreas of both gekkotans comprises four parts: the head of the pancreas (central region) and three lobes: upper, splenic, and lower. This organ develops gradually and is very well distinguished at hatching time. In both gekkotan species, cystic, hepatic, and pancreatic ducts enter the duodenum within the papilla. During gekkotan pancreas differentiation, the connection between the common bile duct and the dorsal pancreatic duct is associated with intestinal rotation, similar to other vertebrates.

Published: April 2024

AbstractPurpose: To introduce a novel design for scan body accessory parts that are reusable, easy to attach and detach without permanent change of the scan body, and can be used with different inter‐implant distances to enhance the accuracy of complete arch implant scans.Materials and Methods: A maxillary polymethylmethacrylate (PMMA) model with a soft tissue replica was fabricated with four implant analogs located at tooth positions 17, 13, 22, and 27 with 18, 25, and 30 mm inter‐implant distances. Four scan bodies (SBs) were attached to the implants. The model was scanned with a laboratory scanner to be used as a reference scan. A total of 40 scans were made with the same intraoral scanner and they were divided equally into two groups. Group A: Complete arch implant scans without scan body accessories (n = 20), and Group B: Complete arch implant scans with scan body accessories (n = 20). Intraoral scans were exported and superimposed on the reference scan using reverse engineering inspection software to be evaluated for 3D deviations, angular deviations, and linear deviations. Statistical analysis was performed with student t‐test and analysis of variance (ANOVA) with repeated measures followed by post hoc adjusted Bonferroni test. The level of significance was set at P = 0.05.Results: The scan body accessories decreased both the 3D and linear deviations, with a statistically significant difference at SB4 for the 3D deviation (P = 0.043) and the linear inter‐implant discrepancies between SB1–SB2 and SB3–SB4 (P = 0.029 and < 0.001), respectively. However, there was no statistically significant difference in angular deviation between the study groups. Implant positions had significant differences within each group.Conclusions: A significant improvement in the accuracy of the complete arch implant digital impression was achieved by using the scan body accessories, particularly in reducing the 3D and linear deviations at the most distant implant positions.

Published: April 2024

AbstractTribology is the science of measuring friction between surfaces. While it has been widely used to investigate texture sensations of food applications, it is seldom applied in pure edible oil systems. In this research, we measured friction, viscosity, and solid fat content (SFC) of nine vegetable oils at 30 and 60°C. Polarized static microscopy was used to assess crystal formation between 60 and 30°C. Descriptive sensory analysis and quantification of oral oil coatings were performed on the oils at 60°C. Expressing the friction factor of oil over the Hersey number (calculated using high sheer‐viscosity values) showed no differences in friction between 30 and 60°C, except for shea stearin. Static microscopy revealed crystallization occurred at 30°C for shea stearin, whereas no or few crystals were present for other oils. At 30°C, friction at 1 × 10−2 m/s showed an inverse correlation with SFC (R = −0.95) and with high shear rate viscosity (R = −0.84), as well as an inverse correlation (R = −0.73) with “oily mouthcoating” perception. These results suggest that friction could be a predictor of fat‐related perceptions of simple oil systems. Additionally, we hypothesize that the presence of crystals in oils could lower friction via a ball‐bearing lubrication mechanism.

AbstractBackgroundIt is unknown if serum concentrations of cobalamin, folate, canine pancreatic lipase immunoreactivity (cPLI), and canine trypsin‐like immunoreactivity (cTLI) obtained postprandially are equivalent to measurements obtained after withholding food in dogs with suspected gastrointestinal disease.Hypothesis/ObjectivesMeasurements of serum concentrations of cobalamin, folate, cPLI, and cTLI postprandially will be equivalent to measurements after 12 hours of withholding food in dogs with signs of chronic gastrointestinal disease. Changes observed will not alter clinical interpretation.Animals51 client‐owned dogs with signs of gastrointestinal disease.MethodsProspective single arm clinical trial. Serum concentrations of cobalamin, folate, cPLI and cTLI 2, 4, and 8 hours postprandially were compared by equivalence testing to values after withholding food for 12 hours (baseline).ResultsMean serum cobalamin concentrations 2 hours (498.1 ± 213.1 ng/L; P = 0.024) and 4 hours (501.9 ± 207.4 ng/L; P = 0.008) postprandial were equivalent to baseline (517.3 ± 211.5 ng/L). Mean serum cTLI 2 hours (31.3 ± 14 μg/L; P < 0.001) and 4 hours (29.6 ± 13.1 μg/L; P = 0.027) postprandial were equivalent to baseline (31.1 ± 15 μg/L). Mean serum folate concentration 2 hours postprandial (15 ± 7.7 μg/L) was equivalent to baseline (13.7 ± 8.3 μg/L; P < 0.001). Equivalence could not be assessed for cPLI due to results below the lower limit of quantification. Feeding altered the clinical interpretation in 27% (cobalamin), 35% (folate), 20% (cTLI), and 12% (cPLI) of dogs.Conclusions and Clinical ImportanceThe clinical interpretation for a substantial number of samples changed after feeding, therefore withholding food before sample collection is prudent.

AbstractIntraspecific variation in cetacean vertebral anatomy as a result of ageing, growth, and sexual dimorphism is poorly understood. Using 3D geometric morphometrics, we investigated allometric patterns, sexual dimorphism, and ontogenetic trajectories in the vertebral column of false killer whale (Pseudorca crassidens). Our data set includes thoracic, lumbar, and caudal vertebrae of 30 specimens, including neonates, juveniles, and adults of both sexes. Vertebral shape was significantly correlated with size within each region. Neonatal vertebral shape differed significantly from juveniles and adults, displaying ontogenetic shape change. Allometric and growth patterns of the vertebral regions, particularly of the lumbar region with the thoracic and caudal regions, differed significantly, which may influence the function and mobility patterns of the vertebral regions during different life stages. Using quantitative methods, we could not conclude that the Pseudorca vertebrae are sexually dimorphic. This study describes for the first time intraspecific vertebral patterns in a cetacean species across ontogenetic stages. Pseudorca individuals live in large pods and swim together, sharing the same swimming mode. The neonates have a more flexible column and swim less efficiently following their mothers to nurse.

AbstractAortic mural thrombus is a rare but important cause of embolic stroke. We report a case of embolic stroke by mobile aortic mural thrombus discuss the acute management and review the literature. A 50‐year‐old man presented sudden onset right hemiparesis and diffusion‐weighted imaging (DWI) of MRI revealed acute embolic stroke. He showed minimum vascular risk factors and no embolic sources. Transesophageal echocardiography (TEE) performed at 5 days after admission showed mobile floating mass lesion in the ascending aorta (19.3 mm × 8.94 mm). He received surgical thrombectomy to prevent further thromboembolic events and the pathological examination showed thrombotic tissue without malignant findings. Mobile aortic mural thrombus is rare but important cause of embolic stroke. Physicians should evaluate embolic sources using TEE as soon as possible in case of cryptogenic stroke in order to exclude critical condition.
Understanding in mathematics: The case of mathematical proofs
Authors: Hamami Yacin , Morris Rebecca Lea 
Published: April 2024

AbstractAlthough understanding is the object of a growing literature in epistemology and the philosophy of science, only few studies have concerned understanding in mathematics. This essay offers an account of a fundamental form of mathematical understanding: proof understanding. The account builds on a simple idea, namely that understanding a proof amounts to rationally reconstructing its underlying plan. This characterization is fleshed out by specifying the relevant notion of plan and the associated process of rational reconstruction, building in part on Bratman's theory of planning agency. It is argued that the proposed account can explain a significant range of distinctive phenomena commonly associated with proof understanding by mathematicians and philosophers. It is further argued, on the basis of a case study, that the account can yield precise diagnostics of understanding failures and can suggest ways to overcome them. Reflecting on the approach developed here, the essay concludes with some remarks on how to shape a general methodology common to the study of mathematical and scientific understanding and focused on human agency.
