Expanding Design Spaces in Digital Composite Materials: A Multi‐Input Deep Learning Approach Enhanced by Transfer Learning and Multi‐kernel Network
Authors: Park Donggeun , Park Minwoo , Ryu Seunghwa 
Published: August 2023

AbstractThis study presents a novel approach to designing digital composite materials with desired mechanical properties by exploring a broad design space based on the spatial arrangements of binary constituents with a variety of materials' properties. Deep learning (DL) models that are trained on limited volume fraction (VF) ratios and limited materials' properties often struggle to accurately predict the mechanical responses of configurations that are not encompassed in the training data. To address this issue, an advanced multi‐input deep learning approach is proposed, enhanced by transfer learning and a multi‐kernel method. This approach can predict the stress field for both seen and unseen configurations in terms of the material properties and VF ratios, while accurately pinpointing stress concentrations at the interface. It can predict stress distribution from finite element method (FEM) accurately with significantly low computational cost, making it an efficient tool for the rapid design and optimization of composites. The incorporation of multiscale kernels in the model enables better capture of local and global features, resulting in more precise predictions. Transfer learning (TL) in the model proves to be an exceptional strategy for exploring new design spaces with minimal data augmentation. This research underscores the potential of DL models in advancing composite materials.

Published: August 2023

AbstractOne route to address climate change is converting carbon dioxide to synthetic carbon‐neutral fuels. Whereas carbon dioxide to CO conversion has precedent in homo‐ and heterogeneous catalysis, deoxygenative coupling of CO to products with C−C bonds—as in liquid fuels—remains challenging. Here, we report coupling of two CO molecules by a diiron complex. Reduction of Fe2(CO)2L (2), where L2− is a bis(β‐diketiminate) cyclophane, gives [K(THF)5][Fe2(CO)2L] (3), which undergoes silylation to Fe2(CO)(COSiMe3)L (4). Subsequent C‐OSiMe3 bond cleavage and C=C bond formation occurs upon reduction of 4, yielding Fe2(μ‐CCO)L. CO derived ligands in this series mediate weak exchange interactions with the ketenylidene affording the smallest J value, with changes to local metal ion spin states and coupling schemes (ferro‐ vs. antiferromagnetism) based on DFT calculations, Mössbauer and EPR spectroscopy. Finally, reaction of 5 with KEt3BH or methanol releases the C2O2− ligand with retention of the diiron core

AbstractIn this research, for the first time, a dedicated sensor was designed to detect Hg+ ions using photoluminescent carbon dots (CDs). Due to the preferred green synthesis of CDs from bio‐resources, carbohydrate‐rich faba bean seeds as a potential carbon precursor were applied to the synthesis of CDs. The CDs were prepared from the faba bean seeds using the hydrothermal method in an aqueous solution in the absence of substances such as an acid or base and any other additives. The synthesized CDs exhibited maximum emission intensity at 387 nm when excited at 310 nm and their luminescence quantum yield was calculated to be ~5.94%. Then, the fluorescence emission of CDs was examined in the presence of different metal ions. Results revealed that the CDs had good selectivity towards the Hg+ ions, so the fluorescence emission was significantly changed in the presence of these ions with a limit of detection (LOD) as low as 0.35 μM. Furthermore, because of their very low cytotoxicity, these CDs can be applied for cell imaging.

AbstractBackground and ObjectivesSurgery is an essential treatment for non‐distant metastatic cutaneous melanoma (NMCM). We aim to construct and validate prognostic nomograms based on surgical approaches and the clinicopathological characteristics of NMCM patients.MethodsData of patients diagnosed with cutaneous melanoma from 2004 to 2015 were identified from the Surveillance, Epidemiology, and End Results (SEER) database. Two online nomograms were constructed to predict the 3, 5‐year melanoma‐specific survival (MSS) for NMCM patients based on the surgical approaches. These nomograms were evaluated by the dynamic Harrell's concordance index (C‐index), decision curve analysis and clinical impact curve. Both internal and external data verification were conducted.ResultsA total of 14,091 NMCM cases were included in this study. The C‐index of the nomograms for the excisional surgery group and amputation group were 0.818 and 0.806, respectively, and 0.763 and 0.731, respectively, in our hospital data validation. After internal and bootstrap verification, our two nomograms showed good accuracy and practicality.ConclusionNMCM patients exhibited equal survival rates independent of resection margin size, while those who needed amputation had worse survival rates. We generated two online nomograms distinguished by surgical approach to predict NMCM patient survival based on clinicopathological characteristics.

AbstractGnetum latifolium var. funiculare Markgr. is a medicinal plant and widely distributed in mountainous areas of Vietnam. Phytochemical investigation on the trunks of this plant afforded eight stilbene derivatives (1–8) including for new compounds (1–4). Their structures were determined based on extensive analyses of HR‐ESI‐MS, 1D and 2D NMR spectra. Among the isolates, compounds 1–3 showed moderate NO production inhibition in LPS‐activated RAW264.7 cells with the IC50 values ranging from 46.81 to 68.10 μM, compounds 4 and 6 showed weak effects with the IC50 values of 96.57 and 79.46 μM, respectively, compared to that of the positive control compound, dexamethasone (IC50 14.20 μM).

Published: August 2023

AbstractRecently, the preparation of some hematene and magnetene ultrathin non van der Waals (non‐vdW) 2D nanoplatelets was reported starting from hematite and magnetite natural iron ores. The present work reports on the determination and evaluation of the nonlinear optical response and the optical limiting (OL) action of these 2D nanoplatelets dispersed in water under ns laser excitation. The obtained results show that both hematene and magnetene exhibit strong nonlinear absorption and refraction, comparable and even larger than those of other van der Waals (vdW) 2D counterpart materials. In addition, due to their strong nonlinear absorption, both hematene and magnetene show exceptional OL performance from the UV to visible, attaining very low values of optical limiting onset (OLon), comparable and even lower than that of vdW 2D nanomaterials, such as graphene, graphene oxide, other transition metal dichalcogenides like MoS2, WS2 and MoSe2, black phosphorous and antimonene. Moreover, hematene was found to exhibit more efficient OL action than magnetene for all the excitation wavelengths studied, attributed to more efficient ligand to metal charge transfer. The present findings open new possibilities for the potential use of these non‐vdW 2D materials in photonics and optoelectronics, e. g., as optical limiters and optical switchers.

AbstractPlant breeders widely use recurrent selection schemes to increase the frequency of favorable alleles for quantitative traits in a population. Although simultaneous selection is complex because it involves several traits combined with selection cycles, the use of selection indexes (SI) is applied to increase the chance of success of the breeding program. Despite many indices are available in the literature, simulations can help breeders to determine which selection index can be better adjusted considering the selection goals, the intensity, and the genetic correlation among traits over breeding cycles. In this context, we estimated the realized genetic gains in a tropical maize haploid inducer population after two cycles of recurrent selection, using external testers and optimizing the simultaneous selection for this breeding population in the long term via stochastic simulations. Furthermore, we proposed a new approach to optimize the initial weights by applying Smith‐Hazel method to maximize the genetic gains for all traits in a balanced way. Overall, the estimated gains in real induction rate were about 63% per cycle, improving the population performance from 0.8% to 2.8%. Moreover, our results confirm that the traditional Smith‐Hazel approach outperformed other methods for long‐term response to selection. Finally, recurrent selection with external testers may be a suitable method to improve the haploid induction rate in tropical maize populations.

Published: August 2023

AbstractUnique magnetic characteristics of cobalt‐ferrite nanoparticles make them suitable for biological imaging and therapeutic applications. Understanding their activity in nanofluids via the ciliary annulus could lead to better contrast agents for magnetic resonance imaging and improved cancer therapy and other medical therapies. This article provides a comprehensive analysis of the theoretical conclusions regarding the transport of a nanofluid by electroosmosis across a ciliary annulus. The nanofluid consists of cobalt‐ferrite nanoparticles (CoFe2O4), water (H2O), and ethylene glycol (C2H6O2). As part of the investigation into constructing a physical model, mathematical analysis is performed based on the conservation of mass, momentum, and energy. Dimension‐free analysis and mathematical constraints are utilized to learn more about the system. By generating differential equations and including suitable boundary conditions, one can obtain exact solutions, which can then be visually inspected. Recent studies have demonstrated an inverse relationship between flow velocity and cilia length, zeta potential, and Helmholtz–Smoluchowski velocity. The streamlines show that the growth of the trapping boluses is affected by several factors, including the nanoparticles’ volume fraction, the cilia's length, the amplitude ratio, the eccentricity, and the zeta potential. These results not only shed light on how nanofluids move, but they also have potential applications in microfluidics, heat transfer, and biomedical engineering.

Abstract
Per- and polyfluorinated substances (PFAS) are a group of thousands of ubiquitously applied persistent industrial chemicals. The field of PFAS environmental research is developing rapidly, but suffers from substantial biases toward specific compounds, environmental compartments, and organisms. The aim of our study was therefore to highlight current developments and to identify knowledge gaps and subsequent research needs that would contribute to a comprehensive environmental risk assessment for PFAS. To this end, we consulted the open literature and databases and found that knowledge of the environmental fate of PFAS is based on the analysis of &lt;1% of the compounds categorized as PFAS. Moreover, soils and suspended particulate matter remain largely understudied. The bioavailability, bioaccumulation, and food web transfer studies of PFAS also focus on a very limited number of compounds and are biased toward aquatic biota, predominantly fish, and less frequently aquatic invertebrates and macrophytes. The available ecotoxicity data revealed that only a few PFAS have been well studied for their environmental hazards, and that PFAS ecotoxicity data are also strongly biased toward aquatic organisms. Ecotoxicity studies in the terrestrial environment are needed, as well as chronic, multigenerational, and community ecotoxicity research, in light of the persistency and bioaccumulation of PFAS. Finally, we identified an urgent need to unravel the relationships among sorption, bioaccumulation, and ecotoxicity on the one hand and molecular descriptors of PFAS chemical structures and physicochemical properties on the other, to allow predictions of exposure, bioaccumulation, and toxicity.

Abstract
As a novel alternative to perfluorooctanoic acid (PFOA), hexafluoropropylene oxide trimer acid (HFPO-TA) has been widely used and has caused ubiquitous water pollution. However, its adverse effects on aquatic organisms are still not well known. In the present study, zebrafish at different life stages were exposed to 0, 5, 50, and 100 μg/L of HFPO-TA for 21 days to investigate reproductive toxicity in zebrafish. The results showed that HFPO-TA exposure significantly inhibited growth and induced reproductive toxicity in zebrafish, including a decrease of the condition factor, gonadosomatic index, and the average number of eggs. Histological section observation revealed that percentages of mature oocytes and spermatozoa were reduced, while those of primary oocytes and spermatocytes increased. In addition, exposure to HFPO-TA at three stages induced a significant decrease in the hatching rate, while the heart rate and normal growth rate of F1 offspring were only significantly inhibited for the exposure from fertilization to 21 days postfertilization (dpf). Compared with the exposure from 42 to 63 dpf, the reproductive toxicity induced by HFPO-TA was more significant for the exposure from fertilization to 21 dpf and from 21 to 42 dpf. Expression of the genes for cytochrome P450 A1A, vitellogenin 1, estrogen receptor alpha, and estrogen receptor 2b was significantly up-regulated in most cases after exposure to HFPO-TA, suggesting that HFPO-TA exhibited an estrogen effect similar to PFOA. Therefore, HFPO-TA might disturb the balance of sex steroid hormones and consequently induce reproductive toxicity in zebrafish. Taken together, the results demonstrate that exposure to HFPO-TA at different life stages could induce reproductive toxicity in zebrafish. However, the underlying mechanisms deserve further investigation. Environ Toxicol Chem 2023;42:2490–2500. © 2023 SETAC

Published: August 2023

AbstractSET domain‐containing 2 (SETD2) is the most frequently mutated gene among all the histone methyltransferases in clear cell renal cell carcinoma (ccRCC). Microarrays, RNA sequencing analysis and exosomes analysis of cellular supernatant were performed after transfection A498 cells with si‐SETD2 or siRNA of negative control. Chromatin immunoprecipitation and Luciferase reporter assay were conducted to evaluate the interaction between SETD2 and miR‐10b. Functional and drug experiments in vitro and in vivo were performed to verify the role of SETD2, miR‐10b and MAP4K4. The results showed that loss of SETD2 mediated downregulation of intracellular and exosomal microRNA‐10b. MAP4K4 were relevant to oncogenesis of ccRCC caused by loss of SETD2 and miR‐10b. SETD2 could directly target miR‐10b and regulate the expression of multidrug resistance (MDR)‐1 (P‐gp170) through JNK pathway, which was one of the downstream pathways of MAP4K4. The coordinated expression of SETD2/H3K36me3/miR‐10b/MAPKs/JNK/MDR pathway was revealed to the progression of ccRCC.

AbstractPurposeA 128‐channel receive‐only array for brain imaging at 7 T was simulated, designed, constructed, and tested within a high‐performance head gradient designed for high‐resolution functional imaging.MethodsThe coil used a tight‐fitting helmet geometry populated with 128 loop elements and preamplifiers to fit into a 39 cm diameter space inside a built‐in gradient. The signal‐to‐noise ratio (SNR) and parallel imaging performance (1/g) were measured in vivo and simulated using electromagnetic modeling. The histogram of 1/g factors was analyzed to assess the range of performance. The array's performance was compared to the industry‐standard 32‐channel receive array and a 64‐channel research array.ResultsIt was possible to construct the 128‐channel array with body noise–dominated loops producing an average noise correlation of 5.4%. Measurements showed increased sensitivity compared with the 32‐channel and 64‐channel array through a combination of higher intrinsic SNR and g‐factor improvements. For unaccelerated imaging, the 128‐channel array showed SNR gains of 17.6% and 9.3% compared to the 32‐channel and 64‐channel array, respectively, at the center of the brain and 42% and 18% higher SNR in the peripheral brain regions including the cortex. For R = 5 accelerated imaging, these gains were 44.2% and 24.3% at the brain center and 86.7% and 48.7% in the cortex. The 1/g‐factor histograms show both an improved mean and a tighter distribution by increasing the channel count, with both effects becoming more pronounced at higher accelerations.ConclusionThe experimental results confirm that increasing the channel count to 128 channels is beneficial for 7T brain imaging, both for increasing SNR in peripheral brain regions and for accelerated imaging.

AbstractBACKGROUNDPlant volatile organic compounds (VOCs) modified by plant‐associated microbes can attract or repel the oviposition of herbivores. Here, we explored the effects of three different fungi on apples' VOCs and the cascading impacts on the oviposition preference of yellow peach moth [YPM, Conogethes punctiferalis (Guenée)].RESULTSAmong Penicillium crustosum‐infected apples (PCA), Rhizopus oryzae‐infected apples (ROA), Colletotrichum gloeosporioides‐infected apples (CGA) and healthy apples (HA), mated YPM females preferred to oviposit eggs on ROA and CGA, and showed significant attractiveness to VOCs from PCA, ROA, and CGA under laboratory conditions. The VOCs analyses showed that there were significant differences between fungi‐infected apples (ROA, CGA) and control treatments (mechanically damaged apples (MDA), HA) in terms of the relative contents of 13 VOCs. The relative contents of ethyl 2‐methylbutyrate, ethyl caprylate, estragole, ethyl hexanoate in ROA and CGA were higher than those in MDA. The relative content of isopropyl 2‐methylbutyrate in ROA was significantly higher than those in HA and CGA. The relative contents of 2‐methylbutyl acetate, butyl 2‐methylbutyrate, hexyl 2‐methylbutyrate, amyl hexanoate, hexyl hexanoate, (E, E)‐α‐farnesene in ROA and CGA were lower than those in HA. The relative content of hexyl acetate in ROA and CGA was significantly higher than that in MDA, but lower than that in HA. Additionally, 10 fungi‐induced VOCs were detected in ROA and/or CGA. When 20 VOCs from ROA and/or CGA were tested as individuals or mixed blends in Y‐tube olfactometer assays, mated YPM females preferred amyl 2‐methylbutyrate, isoamyl 2‐methylbutyrate, isopropyl 2‐methylbutyrate, hexyl propionate (common VOCs in ROA, CGA, and HA), and heptacosane (a fungi‐induced VOC in ROA), but no significant preferences were observed between individual compounds and mixed blends, except for hexyl propionate.CONCLUSIONDifferent fungi infection increased the relative contents of common VOCs from healthy and fungi‐infected apples, which ultimately resulted in the significant attractiveness for the oviposition of mated YPM females. This study clarified why fungi‐infected apples were more attractive to YPMs than healthy apples and screened out the crucial VOCs for YPM oviposition. © 2023 Society of Chemical Industry.
Equipping your facial plastic clinic for office‐based procedures

Published: August 2023

AbstractOffice‐based procedures can be a fulfilling part of the facial plastic practice with the right tools, personnel, and preparation. Equipping the clinic for office‐based procedures has several unique considerations that ultimately impact its success. It is important to strategize preemptively regarding what treatments will be offered and the respective equipment that will allow the safe, cost‐effective, and high‐quality delivery of those treatments. Most procedures in the office‐based setting are cosmetic in nature and there are often overlapping treatment modalities that target similar outcomes. Patient selection and counseling is a crucial step in preparing for office‐based procedures in the effort to maximize patient satisfaction. Nearly all the most common facial plastic procedures can be delivered in the office‐based based setting under local anesthesia and moderate sedation, depending on the expertise of the surgeon. To enable these and other categories of treatments, there are certain expensive pieces of technology that one might consider for their office‐based practice and other fundamental supplies that are necessary for almost all practices. Though the initial investment in equipment can be costly, this article also discusses more affordable alternatives or third‐party sales of devices and equipment. The field of facial plastic surgery is very dynamic and having both peer and mentorship networks is invaluable in navigating some of the financial decisions discussed herein. This article also briefly covers personnel, training, and accreditation considerations.
