BackgroundFocal nodular hyperplasia (FNH) and hepatic adenoma (HA) are two common benign liver lesions with different management options. In particular, resection is considered for large HA lesions to avoid possible bleeding complications or rarely malignant degeneration.PurposeTo determine whether early enhancement of a draining hepatic vein (EDHV) and absence of perilesional enhancement (PLE) on arterial phase MR images are useful for distinguishing FNH from HA.Study TypeRetrospective.PopulationA total of 34 patients: 16 with FNH and 18 with HA lesions.Field Strength/SequenceA1.5 T, axial T1 fat‐suppressed arterial postcontrast.AssesmentFour abdominal radiologists blinded to pathologic diagnosis assessed for the presence or absence of EDHV in association with the lesion, definitively characterized by pathology. This was considered present if contrast could be identified in a hepatic vein contiguous with the lesion in question. Secondarily, PLE was evaluated.Statistical TestsFleiss's multirater kappa statistic, Chi‐squared statistic, Phi‐coefficient. Significance level P < 0.05.ResultsConsidering all observations obtained from the four readers, an EDHV was identified with FNH 48.5% of the time. EDHV was seen with HA in 8.8% of cases. PLE was seen with significantly greater frequency in HA. The presence of an EDHV was associated with the absence of PLE.Data ConclusionIn a lesion that may be either an FNH or HA, confident identification on arterial phase images of an EDHV should lead the reader to favor FNH, while the presence PLE should dissuade the reader from FNH.Evidence Level4.Technical EfficacyStage 2.

AbstractThe depth of the aerosol layer at the Villum Research Station at Station Nord in the high Arctic is analysed based on 8 years of observations from a ceilometer and one full year from a wind lidar. The layer is of particular interest for aerosol process modelling and atmospheric chemistry studies. The depth of the aerosol layer is assigned to the inflection point in the attenuated backscatter profile by two methods; one is based on polynomial approximation of the profile and the other is direct numerical differentiation. The analysis is based on two types of hourly profiles; one consists of averaging the attenuated backscatter observations and the other by computing the median. Due to sporadic occurrence of outliers in the ranges around 50 m in the ceilometer observations, this part of the profile is not used in this study. Restricting the observations to heights above 100 m, the depths of the aerosol layer are found to be typically ≈230 m. It varies little between winter and summer, but the spread in the depth is larger during the winter as compared to summer. To extend the study of the aerosol‐layer depth below 100 m, a method is applied that combines the ceilometer measurements with the carrier‐to‐noise ratio from the wind lidar. The results are available for 2018 only, and they show aerosol‐layer depths below ≈80 m as well as depths around 230 m and they show few observations between ≈80 and ≈230 m. Near the ground, the observed backscatter exhibits a pronounced seasonal variation, having low values during the summer and high values during the winter. The strength of the seasonal variability decreases with height, especially above the aerosol‐layer depth, and is virtually absent at 1 km.

AbstractChronic wounds seriously affect the quality of life of the elderly, obese people, and diabetic patients. The excessive inflammatory response is a key driver of delayed chronic wound healing. Although lavender essential oil (EO [lav]) has been proven to have anti‐inflammatory and accelerate wound curative effects, the specific molecular mechanism involved is still ambiguous. The results showed that the wounds treated with lipopolysaccharide (LPS) not only had delayed healing, but also the expression levels of pro‐inflammatory cytokines, such as tumor necrosis factor‐α (TNF‐α), interleukin‐6 (IL‐6), interleukin‐1β (IL‐1β), and the inflammatory mediator protein, high‐mobility group box 1 protein (HMGB‐1), in the wound tissues were significantly increased. However, treatment of LPS‐induced chronic wounds with EO (lav) accelerated wound healing and decreased IL‐1β and HMGB‐1 expression levels. It was further found that LPS induced macrophage pyroptosis to produce IL‐1β. After treatment with EO (lav), the expression level of macrophage pyroptosis marker Gasdermin D (GSDMD) and pyroptosis‐related cytotoxic effects were significantly reduced. Immunofluorescence results also directly indicate that EO (lav) can protect macrophages from LPS‐induced pyroptosis. Moreover, EO (lav) can down‐regulate expression levels of IL‐1β, GSDMD, and nucleotide‐binding oligomerization domain‐like receptor protein 3 (NLRP3) in the caspase‐11‐related pyroptotic signaling pathway. This study demonstrates that EO (lav) can reduce proinflammatory factor production and ameliorate inflammatory response by inhibiting macrophage pyroptosis, which accelerates LPS‐induced chronic wound healing.

AbstractPreventing soil salinization is key to the healthy development of agroecosystems in arid regions. Notably, long‐term anthropogenic irrigation accelerates secondary salinity accumulation in arid areas; however, the regional‐scale spatial patterns of soil salinity pre‐ and post‐irrigation season remain unclear. Accordingly, field observations over two periods (n = 182 samples), along with environmental covariates and the randomForest algorithm, were used to estimate the horizontal and vertical spatial distributions (12 soil depths) of soil salinity in the Weiku Oasis (0–60 cm) at a 30 m spatial resolution. The results showed that the prediction accuracy was greater for the non‐irrigated season than for the irrigated season. Moreover, soil salinity was low in the interior of the oasis, high in the desert oasis interlacing zone, and significantly decreased with increasing soil depth. Variable contributions indicated that the effects of SoilGrids variables on soil salinity increased with greater soil depth. During the irrigation season, an inflection point for salt aggregation was observed at ~55 cm for farmlands, grasslands, and shrubs, with the greatest variation seen in farmlands. The findings here provide insights into the improvement of irrigation techniques in arid zone agroecosystems.

AbstractObjectiveThis study aims to identify determinants of high impact, measured by Impact Factor (IF) and Eigenfactor score, among otolaryngology journals.MethodsBibliometric data of “otorhinolaryngology” journals were collected from the Journal Citation Reports (JCR) database. For the years 2009–2020, we collected normalized Eigenfactor score, 5‐year IF, immediacy index, fraction of IF from journal‐self citation, proportion and magnitude of published citable articles, and total citation counts. High‐IF and ‐Eigenfactor journals were considered those within the top‐quartile of that metric each respective year.ResultsHigh‐IF and ‐Eigenfactor otolaryngology journals displayed higher 5‐year IFs, immediacy indexes, and IF without self‐citation (p < .05 for all years) including total citations counts and citable articles when ranked by Eigenfactor (p < .05 for all years). Otolaryngology IF correlated with 5‐year IF and immediacy index within the same year (p < .05 for all years) and from previous years (p < .05 for all years; p < .05 for 2017‐2018; p > .05 for 2009‐2016). Eigenfactor correlated with 5‐year IF, total citation counts, and citable articles within the same year (p < .05 for all years) and previous years (p < .05 for 2013–2018). Multilinear regression revealed that 5‐year IF (p < .05 for 2009–2018) and immediacy index from the prior 2 years (p < .05 for 2017‐2018; p > .05 for 2009‐2016) predicted 2019 IF. Similarly, 5‐year IF, total citation counts, and citable articles (p < .05 for 2013–2018) predicted 2019 Eigenfactor score.ConclusionSustained publication of impactful articles is the dominant driver of high IF and Eigenfactor score. Eigenfactor score reflects a unique evaluation of otolaryngology journals; ranking otolaryngology journals by their Eigenfactor scores significantly alters journal ranking compared to ranking by IF.Level of evidenceNA.

AbstractAntimony sulfide (Sb2S3), a binary chalcogenide, has recently emerged as a promising candidate for photovoltaics due to its high absorption coefficient, facile processing, and lower toxicity. However, high‐performance photodiodes based on Sb2S3 have not been achieved and systematically investigated. Herein, Sb2S3‐based photodiodes based on conventional and inverted structures are developed, and their charge transport and spectral dependent quantum efficiency of these two types of devices are carefully modulated. After optimization, the conventional photodetectors achieve broadband responsivity up to 0.3 A W−1, high specific detectivity of 1.25 × 1012 Jones, and fast response speed of 6.4 µs with a small bias voltage of −0.5 V. On the other hand, the inverted devices exhibit imbalanced charge transport and color discrimination, which is promising for narrowband photodetection. These distinct device performances are highly dependent on the device architecture, which is crucial for designing efficient chalcogenide‐based optoelectronic devices.

Published: February 2023

AbstractObjectivesTo investigate quantitatively the cutting efficiency and the thermal effects in the surrounding soft tissues of incisions that are induced by a 940 nm‐diode laser with different power settings.Materials and MethodsFifty‐four gingival samples were prepared from the lower jaws of freshly slaughtered German‐land race pigs and were randomly divided into 9 groups (n = 6) according to the adjusted output power (1, 1.5, 2, 2.5, 3, 3.5, 4, 5 and 6 W). Five incisions were implemented for each sample using a diode laser (940 nm) in continuous wave with an initiated tip resulting in 30 incisions for each experimental group utilizing a three‐dimensional computer‐controlled micropositioner. The samples were prepared for histometric evaluation using a transmitted light microscope. The cutting depth and width and the thermal damage were recorded for each sample and the efficiency factor γ was calculated.ResultsThe highest cutting efficiency (γz = 0.81 ± 0.03) exhibited the group with 5 W output power (p < 0.05), while the lowest (γz = 0.45 ± 0.11) showed the 1‐W group (p < 0.05). Over 3.5 W there was a rapid increase in the size of thermal damage of the incisions, especially for 6 W, which presented the largest.ConclusionsThe most effective power parameters of diode laser (940 nm) for soft tissue surgery were from 3 to 5 W. The outcomes of the current study may help to establish clinical protocols for the use of diode lasers (940 nm) in soft tissue surgery in contact mode assisting dental professionals to achieve optimal clinical results and avoid complications.

AbstractThe 19F NMR chemical shifts of 13 trifluoromethyl derivatives of alkenes, pyrimidines, and indenes were calculated at the DFT level using the BhandHLYP, BHandH, PBE, PBE0, O3LYP, B3LYP, KT2, and KT3 functionals in combination with the pcS‐2 basis set. Best result was documented for the BHandHLYP functional: The mean absolute error (MAE) of 0.66 ppm for the scaled values was achieved for the range of about 20 ppm. Solvent, vibrational, and relativistic corrections were found to be rather small, especially when taken in combination, generally demonstrating a slight decrease in the difference between calculated and experimental fluorine chemical shifts. As a measure of the practical importance of these compounds, one should recall that the growing number of life science products that contain trifluoromethyl groups provides a continuing driving force for the development of an effective methodology that enables both regio‐ and stereoselective introduction of trifluoromethyl groups into both aliphatic and aromatic systems.

PurposeTo quantify the variations of the power‐law dependences on diffusion time t or gradient frequency of extracellular water diffusion measured by diffusion MRI (dMRI).MethodsModel cellular systems containing only extracellular water were used to investigate the dependence of , the extracellular diffusion coefficient. Computer simulations used a randomly packed tissue model with realistic intracellular volume fractions and cell sizes. DMRI measurements were performed on samples consisting of liposomes containing heavy water(D2O, deuterium oxide) dispersed in regular water (H2O). was obtained over a broad range (∼1–1000 ms) and then fit power‐law equations and .ResultsBoth simulated and experimental results suggest that no single power‐law adequately describes the behavior of over the range of diffusion times of most interest in practical dMRI. Previous theoretical predictions are accurate over only limited ranges; for example, is valid only for short times, whereas or is valid only for long times but cannot describe other ranges simultaneously. For the specific range of 5–70 ms used in typical human dMRI measurements, matches the data well empirically.ConclusionThe optimal power‐law fit of extracellular diffusion varies with diffusion time. The dependency obtained at short or long limits cannot be applied to typical dMRI measurements in human cancer or liver. It is essential to determine the appropriate diffusion time range when modeling extracellular diffusion in dMRI‐based quantitative microstructural imaging.

PurposeTo evaluate pseudo‐continuous arterial spin labeling (pCASL) and velocity‐selective arterial spin labeling (VSASL) for quantification of spinal cord blood flow (SCBF) in the rat thoracolumbar spinal cord.MethodsLabeling efficiency (LE) was compared between pCASL and three VSASL variants in simulations and both phantom and in vivo experiments at 9.4 T. For pCASL, the effects of label plane position and shimming were systematically evaluated. For VSASL, the effects of composite pulses and phase cycling were evaluated to reduce artifacts. Additionally, vessel suppression, respiratory, and cardiac gating were evaluated to reduce motion artifacts. pCASL and VSASL maps of spinal cord blood flow were acquired with the optimized protocols.ResultsLE of the descending aorta was larger in pCASL compared to VSASL variants. In pCASL, LE off‐isocenter was improved by local shimming positioned at the label plane and the anatomical level of labeling for the thoracic cord was only viable at the level of the T10 vertebra. Cardiac gating was essential to reduce motion artifacts. Both pCASL and VSASL successfully demonstrated comparable SCBF values in the thoracolumbar cord.ConclusionpCASL demonstrated high and consistent LE in the thoracic aorta, and VSASL was also feasible, but with reduced efficiency. A combination of cardiac gating and recording of actual post‐label delays was important for accurate SCBF quantification. These results highlight the challenges and solutions to achieve sufficient ASL labeling and contrast at high field in organs prone to motion.
Exploring the Use of Price Indices to Adjust Angler Expenditure Profiles over Time

Published: February 2023

Abstract
This research evaluated a price-adjusting methodology to update trip expenditure information annually for economic impact analysis. Historic expenditure profiles for nonlocal Texas anglers and nonresident (out-of-state) anglers were generated from 1995 angler survey data collected at Lake Fork Reservoir; these data were then adjusted over a 20-year period using price indices produced by the U.S. Bureau of Labor Statistics. To determine whether the price adjustment methodology was appropriate for angler expenditures, a replication of the 1995 angler survey was conducted in 2015 to compare adjusted expenditures to actual expenditures. Preliminary results concluded that expenditure profiles for nonlocal and nonresident anglers were different between the two periods but also suggested that significant differences within angler groups existed between the two angler surveys, so anglers were regrouped based on trip length rather than origin of trip. Adjusted average daily expenditure total for 1-d trips during the 1995 study (US$69.38) was similar to the average daily expenditure total of the 2015 study ($77.18), and the same conclusion was found for all item categories. For multiple-day trips, adjusted average daily expenditure ($130.48) was similar to the average daily expenditure ($128.04) in 2015. Expenditure profiles were then combined with effort data in the IMPLAN (Impact Analysis for Planning) software model to generate estimates of economic impacts. Total economic impacts of 1-d fishing trips to Lake Fork Reservoir were estimated to be $1.28 million and $1.43 million when using the adjusted and actual expenditure profiles, respectively. For multiple-day trips, economic impacts were estimated to be $10.82 million and $10.80 million for the adjusted and actual expenditure profiles, respectively. Although economic impact analysis must continue to identify where trip expenditures originate, results suggest that adjusting trip expenditures over time can be done using price indices and should be conducted based on trip length regardless of origin.

Abstract
Muskellunge Esox masquinongy, Northern Pike E. lucius, Walleye Sander vitreus, and Largemouth Bass Micropterus salmoides are popular sport fish that often co-occur in aquatic systems. Although numerous studies have investigated interactions among these species, the simultaneous evaluation of diet patterns and niche overlap among all four species has not been conducted. Our experimental design aimed to quantify diet overlap among Muskellunge and the other piscivores, while lakes without Muskellunge were also sampled to compare the diets of the other piscivores in their presence or absence. Diets of piscivores from 10 Minnesota lakes were collected via gastric lavage and quantified using an index of relative importance. Diets of individual species were compared among seasons and predator length categories, and among-species comparisons were also conducted by season and relative to Muskellunge presence using permutational multivariate ANOVA (PERMANOVA). Muskellunge consumed a wide range of prey, whereas Northern Pike and Walleye diets consisted primarily of Yellow Perch Perca flavescens and centrarchids. Largemouth Bass consumed more invertebrates, especially crayfish Faxonius spp. No species exhibited seasonal diet shifts, but diets were different among length categories for all species except Walleye. Although nonmetric multidimensional scaling ordinations indicated shared prey use, PERMANOVA results indicated that the diets of Muskellunge and Largemouth Bass were most different from each other and the other piscivores' diets across all seasons. Conversely, Northern Pike and Walleye diets were similar regardless of season or Muskellunge presence. Finally, lake-scale habitat variables were correlated with piscivore diets, and Yellow Perch abundance was correlated with Walleye diets. Our results indicate that while Muskellunge, Northern Pike, Walleye, and Largemouth Bass can coexist in a variety of lakes, populations of important prey and habitat variables should be examined before management actions (e.g., stocking) are implemented to ensure adequate prey availability and to ensure that competition among these piscivores is not increased to the detriment of existing fisheries.
Mesh‐size independent rigid‐body spring network for simulation of the dynamic fracture behavior of concrete
Authors: Choo Bonhwi , Park Ji Woon , Nam Young Jun , Hwang Young Kwang , Lim Yun Mook 
Published: February 2023

AbstractIn this study, a numerical approach is developed for simulating the rate‐dependent behaviors of concrete without mesh sensitivity. The rheological units (e.g., dashpot) are integrated with the six directional springs in the rigid‐body spring network (RBSN) elements to reflect the rate‐dependent behavior of concrete. Previously, the viscoplastic damage model was associated with the elemental degrees of freedom. However, in the present approach, a viscoelastic constitutive law is newly defined for the normal direction as a function of the strain rate, from which the internal forces can be updated from the regularized elemental stresses. Such improvements are validated through the numerical simulations of the direct tensile test and spalling test using the modified split‐Hopkinson pressure bar (SHPB). The simulated results show consistent structural responses without mesh dependence on the strain rate. In addition, the influences of the softening curve shapes on the crack localizations are examined. It is shown that the rheological parameters can be optimized and determined for consistent applications through virtual experiments. The proposed numerical approach enables the mesh construction procedure without concerning the mesh‐size sensitivity due to the strain rate, and various applications are expected for the simulations of detailed numerical models of concrete materials and structures under high loading rates.
