The present experiment was carried out to evaluate the nutritional profile of 10 advanced mutant lines of Indian mustard (Brassica juncea) along with 3 checks. Observation was recorded for 12 biochemical traits, and the analysis of variance (ANOVA) revealed significant variation among all characters under study. The findings demonstrate higher GCV and PCV in the case of oleic acid and arachidic acid which significantly impact these traits' inflow. Except for the total phenol content (mg GAE/g) and the total soluble protein content, all the other traits show high heritability and a significant genetic advance, indicating traits controlled by additive gene action. In the correlation study, it was found that the oleic acid, linoleic acid, linolenic acid, palmitic acid, eicosenoic acid and stearic acid are significantly negatively correlated with erucic acid. This indicates that improving these characteristics leads to decreased erucic acid content. The path diagram also indicates a high direct positive effect of total soluble protein (%) and stearic acid and a significant high direct negative effect of total phenol content and palmitic acid on total oil content. Three of the twelve PCs had eigenvalues greater than 1.0, explaining 83.36% of the variance. PC I accounted for 37.48% and PC II for 30.42% of the overall variance. Based on hierarchical cluster analysis, 13 Brassica genotypes were divided into 4 clusters. Genotypes TM-313, TM 305-1, TM 306-1, B9 show the most divergence and can be used in future breeding programs.
Dark or disturbed?: Predicting aggression from the Dark Tetrad and schizotypy
Authors: Paulhus Delroy L. , Gupta Rohin , Jones Daniel N. 
Published: August 2021

AbstractResearch on the personality foundations of aggression typically implicates either (a) aspects of the so‐called “Dark Tetrad” or (b) severe mental disturbance (psychosis). The appearance of psychotic symptoms in general populations is termed schizotypy. We conducted two studies to compare the effects of dark personalities and schizotypy on aggression. Study 1 used standard inventories to investigate the overlap of Dark Tetrad traits with schizotypy in a sample of 977 undergraduates. All tetrad traits except narcissism were positively associated with schizotypy, but only at moderate levels. Study 2 administered the same personality battery to 303 members of an online community sample: Aggression outcomes were measured with both self‐reports and a behavioral measure—the Voodoo Doll Task. Regression analyses determined the unique contributions of the five personality variables. Two dark traits—psychopathy and sadism—were strong predictors of self‐report aggression. Schizotypy added incrementally to the Dark Tetrad in predicting both self‐report and behaviorally measured aggression.
Patients’ Perceptions of Person‐Centered Care in Early Rheumatoid Arthritis: A Qualitative Study
Authors: Landgren Ellen , Bremander Ann , Lindqvist Elisabet , Nylander Maria , Larsson Ingrid 
Published: August 2021

ObjectiveMost research on patient experiences of rheumatoid arthritis (RA) care is performed with patients who have established RA and less often with patients with early RA. Experiences of and expectations about health care may change over time, which is why the aim was to explore patients’ perceptions of person‐centered care (PCC) early in the RA disease course.MethodsThirty‐one patients with early RA were interviewed in this qualitative study. An abductive qualitative content analysis was conducted based on the framework of McCormack and McCance (1,2). The four constructs, prerequisites, care environment, person‐centered processes, and person‐centered outcomes, constituted the four categories in the deductive part of the study. An inductive analysis generated 11 subcategories exploring the content of PCC.ResultsFor patients with early RA, PCC was described in terms of 1) prerequisites including being treated with respect, meeting dedicated health care professionals, and meeting professional competence; 2) care environment including having access to a multidisciplinary team, having access to health care, and encountering a supportive organization; 3) person‐centered processes including being listened to, being supported, and being involved in decision‐making; and 4) person‐centered outcomes including being satisfied with received health care and achieving optimal health.ConclusionGenuine PCC is important for patients early in the RA disease course, supporting the implementation of a person‐centered approach during all stages in the health care system. This study contributes to information about how to further develop person‐centeredness in rheumatology care.
Iterative identification methods for a class of bilinear systems by using the particle filtering technique
Authors: Li Meihang , Liu Ximei 
Published: August 2021

SummaryThis article mainly studies the iterative parameter estimation problems of a class of nonlinear systems. Based on the auxiliary model identification idea, this article utilizes the estimated parameters to construct an auxiliary model, and uses its outputs to replace the unknown noise‐free process outputs, and develops an auxiliary model least squares‐based iterative (AM‐LSI) identification algorithm. For further improving the parameter estimation accuracy, we use a particle filter to estimate the unknown noise‐free process outputs, and derive a particle filtering least squares‐based iterative (PF‐LSI) identification algorithm. During each iteration, the AM‐LSI and PF‐LSI algorithms can make full use of the measured input–output data. The simulation results indicate that the proposed algorithms are effective for identifying the nonlinear systems, and can generate more accurate parameter estimates than the auxiliary model‐based recursive least squares algorithm.
Soil quality assessment of an agroforestry system following long‐term management in the Ozark Highlands

Published: August 2021

AbstractThe Soil Management Assessment Framework (SMAF) is a quantitative soil quality (SQ) evaluation tool that is widely applied to assess soil response to specific agricultural management practices over time. Considering the reported SQ benefits of agroforestry (AF) systems and the potential usefulness of SMAF, the objective of this study was to evaluate the effects of tree species (pecan [Carya illinoinensis (Wangenh.) K. Koch] and northern red oak [Quercus rubra L.]), soil fertility source (poultry litter [PL] and inorganic N fertilizer [control]), and soil depth (0–15 and 15–30 cm) on SMAF‐derived SQ indices after 17 yr of management at an AF site in northwest Arkansas. Averaged across soil depth, soil organic C scores under red oak with PL application had a lower score (0.48) than red oak fertilized with inorganic N (0.60) and pecan receiving long‐term PL applications (0.60), which did not differ from pecan with inorganic N fertilizer application (0.51). Averaged across soil depth, the soil quality index (SQI) for pecan receiving PL applications was 1.1 times greater than that under red oak receiving PL and soils under pecan receiving inorganic N fertilizer. Soil quality assessments use in AF are novel, as SMAF has not been used to identify soil health in these systems, although specific tree crop codes need to be developed in SMAF. Results of this study demonstrate that soils planted under various tree species respond dissimilarly to fertilizer sources and that management may improve overall SQ.

AbstractSince information islimited regarding N management and tillage options for corn (Zea mays L.) grown on claypan soil in the eastern Great Plains, the objective of this study was to determine the effect of preplant and side‐dress N applications on corn grown in conventional‐ and no‐till systems. The yield penalty for no‐till grown corn was nearly 20% due partially to an 8% stand reduction, but also to lower kernel weight and kernels ear–1 than with conventional till. These yield and yield component reductions with no‐till may be because of lower dry matter production and N uptake throughout the growing season. The general lack of interactions suggest that N management system effects on corn were not influenced by tillage system selection. Fertilizing with N more than doubled corn yields primarily by nearly doubling the number of kernels ear–1, but with additional increases in kernel weight and average number of ears plant–1. Averaged over years, split‐N resulted in up to 15% greater yield, and additional side‐dress N resulted in up to 28% greater yield than when 168 kg N ha–1 was applied only at preplant, with no yield reduction for delaying side‐dress application from V6 to V10. The relationship of relative N uptake to relative corn yield approached a direct 1:1 relationship by R1 (silking). The decision of whether to split‐apply fertilizer N or to add additional N, regardless of tillage system, will likely be influenced by economic factors, but side‐dress N applications may extended to the V10 stage with no yield penalty.

AbstractTropical rainforests are characterized by a high diversity of plant species. Each plant species presents with differential phenological patterns in fruit production. In some species, all individual trees produce fruit simultaneously within clustered periods; whereas in others, each individual tree fruits at irregular time intervals. By observing this pattern, some primate species use the presence of fruits in one tree as a cue to find fruit in other trees of the same synchronously fruiting tree species. Here, we investigated whether the highly frugivorous Javan gibbons (Hylobates moloch) in Gunung Halimun‐Salak National Park in Indonesia have knowledge of synchronous characteristics of fruiting trees and whether they can further distinguish fruit species with different synchrony levels, that is, tree species with highly synchronous fruiting patterns versus tree species with less synchronous fruiting patterns. Across 12 months we collected biweekly phenological data on 250 trees from 10 fruit species and observed Javan gibbons' visits to those species. We found that a fruit discovery in the beginning of fruiting seasons triggered gibbons to visit trees of the same fruit species. However, gibbons' visit rates did not differ between highly synchronous and asynchronous species. Our results suggest that Javan gibbons have knowledge of synchronous characteristics of fruiting trees in general, but they do not differentiate highly synchronous versus asynchronous fruit species. We speculate that Javan gibbons, who live in relatively small ranges with very low tree density of preferred fruit species, are likely able to track and remember fruiting states of individual trees without needing to distinguish fruit species with different synchrony levels. Moreover, gibbons may make little benefit of distinguishing highly synchronous versus asynchronous fruit species, probably due to gibbons' heavy use of asynchronous figs. Our study provides an insight into how gibbon's foraging strategies may have been shaped in response to their ecological environment.

AbstractThe ability of mitochondrial DNA (mtDNA) to form G‐quadruplex (GQ) structures suggest their role in diseases involving mitochondrial dysfunction. Detection and visualization of GQ structures specific to mitochondria using fluorescent probes aid in monitoring mtDNA dynamics and homeostasis. Herein, we report the first study of flavylium‐methine rotor probes (FLV1 and FLV3) for discrimination of GQ and non‐GQ structures through turn‐on near infrared (NIR) fluorescence response. The target‐induced disaggregation (TID) and restricted intramolecular rotation (RIR) of FLV1 in the presence of GQ specific to VEGF oncogene leading to significant fluorescence enhancement and delayed lifetime. The colocalization studies with different organelle trackers confirmed selective localization of FLV1 in mitochondria. Nuclease digestion assays showed mitochondria‐specific accumulation of the probe is independent of membrane potential and selectively bind mtDNA GQ. Our study demonstrates the biocompatible and photostable flavylium‐methine dyes as a new category of probes to selectively label mitochondria and target mtDNA GQ in live and fixed cells.

AbstractThree‐dimensional (3D) printing technology has become more affordable, accessible, and relevant in healthcare, however, the knowledge of transforming medical images to physical prints still requires some level of training. Anatomy educators can play a pivotal role in introducing learners to 3D printing due to the spatial context inherent to learning anatomy. To bridge this knowledge gap and decrease the intimidation associated with learning 3D printing technology, an elective was developed through a collaboration between the Department of Anatomy and the Makers Lab at the University of California, San Francisco. A self‐directed digital resource was created for the elective to guide learners through the 3D printing workflow, which begins with a patient's computed tomography digital imaging and communication in medicine (DICOM) file to a physical 3D printed model. In addition to practicing the 3D printing workflow during the elective, a series of guest speakers presented on 3D printing applications they utilize in their clinical practice and/or research laboratories. Student evaluations indicated that their intimidation associated with 3D printing decreased, the clinical and research topics were directly applicable to their intended careers, and they enjoyed the autonomy associated with the elective format. The elective and the associated digital resource provided students with the foundational knowledge of 3D printing, including the ability to extract, edit, manipulate, and 3D print from DICOM files, making 3D printing more accessible. The aim of disseminating this work is to help other anatomy educators adopt this curriculum at their institution.

AbstractOhmic contacts are of critical importance to improve the performance of semiconductor devices as well as those of low‐dimensional materials. Halogen‐bridged metal complexes (MX‐Chains) are fascinating quasi‐one‐dimensional (1D) electronic materials. However, reports on the electrical characteristics of MX‐Chains remain elusive. Herein, we report the electrical characteristics of single crystals of [Ni(chxn)2Br]Br2 (chxn: (1R,2R)‐(−)‐1,2‐cyclohexanediamine), which is a 1D Mott insulator, using different probe arrangements. [Ni(chxn)2Br]Br2 was shown for the first time to exhibit Ohmic characteristics on the crystal surface, albeit that the conductivity behavior of the interior of the crystal is nonlinear due to the Joule heating effect. The current flow on the surface is shallow (a few micrometers in depth) despite the millimeter‐scale crystal size; this phenomenon is strongly connected to its structural anisotropy. The Ohmic contact revealed in this work should be valuable for the application of MX‐Chains as electronic devices in the near future.

AbstractSolar‐driven photocatalysis holds great potential for energy conversion, environmental remediation, and sustainable chemistry. However, practical applications of conventional photocatalytic systems have been constrained by their insufficient ability to harvest solar radiation in the infrared spectrum. Lanthanide‐doped upconversion materials possess high photostability, tunable absorption, and the ability to convert low‐energy infrared radiation into high‐energy emission, making them attractive for infrared‐driven photocatalysis. This review highlights essential principles for rational design of efficient photocatalysts. Particular emphasis is placed on current state‐of‐the‐arts that offer enhanced upconversion luminescence efficiency. We also summarize recent advances in lanthanide‐doped upconversion materials for photocatalysis. We conclude with new challenges and prospects for future developments of infrared‐driven photocatalysts.
