Research has shown that accounting for moral sentiment in natural language can yield insight into a variety of on- and off-line phenomena such as message diffusion, protest dynamics, and social ...distancing. However, measuring moral sentiment in natural language is challenging, and the difficulty of this task is exacerbated by the limited availability of annotated data. To address this issue, we introduce the Moral Foundations Twitter Corpus, a collection of 35,108 tweets that have been curated from seven distinct domains of discourse and hand annotated by at least three trained annotators for 10 categories of moral sentiment. To facilitate investigations of annotator response dynamics, we also provide psychological and demographic metadata for each annotator. Finally, we report moral sentiment classification baselines for this corpus using a range of popular methodologies.
In this study, a steady state and time‐dependent exciton diffusion model including singlet and triplet excitons coupled with a modified Poisson and drift‐diffusion solver to explain the mechanism of ...hyper triplet–triplet fusion (TTF) organic light‐emitting diodes (OLEDs) is developed. Using this modified simulator, various characteristics of OLEDs, including the current‐voltage curve, internal quantum efficiency, transient spectrum, and electric profile are demonstrated. This solver can also be used to explain the mechanism of hyper‐TTF‐OLEDs and analyze the loss from different exciton mechanisms. Furthermore, we perform additional optimization of hyper‐TTF‐OLEDs that increases the internal quantum efficiency by ≈33% (from 29% to 40%).
In this work, a time ‐dependent exciton diffusion solver coupled with Poisson and drift‐diffusion solver for triplet‐triplet fusion (TTF) organic light‐emitting diodes (OLEDs) is developed to demonstrate the mechanism of TTF‐ and hyper‐TTF‐OLEDs. The loss mechanism of hyper TTF‐OLED is investigated, and optimized interrnal quantum efficiency can be improved from 29% to 40%.
This study aims to evaluate the effectiveness of a tracking program on the functional maturation rate of arteriovenous fistula (AVF).
Two major clinical outcomes (commencement of cannulation and ...functional maturation) of created AVFs were compared between two cohorts. (i) Cohort 1: historical cohort; (ii) Cohort 2: AVFs created after implementation of the tracking project. Multivariable Cox regression models were used to assess the association between cohort allocation and the two major clinical outcomes.
Data of 114 and 141 patients were analyzed respectively from Cohorts 1 (historical data) and 2 (with AVF tracking). After adjustment of covariates in the multivariable analysis, the AVFs created in Cohort 2 were more likely to be cannulated earlier (adjusted HR: 2.82; 95% CI: 1.97-4.05; p < 0.001), compared to those in Cohort 1. Similarly, the AVFs of Cohort 2 patients had significantly higher probability of functional maturation (adjusted HR: 1.81; 95% CI: 1.31-2.48; p < 0.001) than fistulas in Cohort 1. Cannulation was commenced for half of the AVFs by 4.1 months post-creation in the historical cohort (Cohort 1), whereas in the post-tracking cohort, 50% of the AVFs were cannulated by 2.3 months after creation (p < 0.001). It took 5.5 and 4.3 months for 50% of the AVFs created in Cohort 1 and Cohort 2 patients to achieve catheter-free functional maturation, respectively (p = 0.06).
An AVF tracking program with maturation target for the access surgeons, together with a standardized tracking, feedback, and clinical strategy adjustment system is able to improve the AVF functional maturation rate.
Starburst triarylamines 2 and 3 were electropolymerized to form electrochromic thin films. Film from 2 showed intense absorption at 372 nm before voltage was applied. There were two absorption bands ...at 496 nm and 1000−2000 nm at 0.3 V, and a broad band, which peaked at 807 nm at 0.6 V. Film from 3 showed intense absorption at 372 nm before voltage was applied. There were two absorption bands at 498 nm and 1000−2000 nm at 0.3 V, and a broad band, which peaked at 890 nm at 0.7 V. The switching time studies revealed that thin film from 2 would require 3 s at 0.46 V for switching absorbance at 1600 nm and 1 s for bleaching. It would also require 4 s at 0.66 V for coloration at 800 nm and 2 s for bleaching. On the other hand, thin film from 3 would require 3 s at 0.46 V for switching absorbance at 1500 nm and 1 s for bleaching. It would also require 3.3 s at 0.76 V for switching absorbance at 900 nm and 1.5 s for bleaching. Electropolymerized thin films of 2 and 3 were also used as the surface modification layers to modify the surface of ITO for polymeric light emitting diode (PLED). To evaluate the performance of the modification layer, we selected a device of ITO/modification layer/PVK−Alq3−coumarin 6/metal electrode as the standard for comparison. We discovered that co-electropolymerization of the triarylamines 2 or 3 with poly(vinylcarbazole) (PVK) on ITO greatly reduces the turn-on voltage of the PLED devices and their performance is comparable to that of the commercially available PEDOT.
In this work, we developed a both stable and time-dependent exciton diffusion model including singlet and triplet exciton coupled with a modified Poisson & drift-diffusion solver to demonstrate the ...mechanism of triplet-triplet fusion (TTF) OLEDs. Using this modified simulator, we can demonstrate the characteristics of OLEDs including current-voltage curve, quantum efficiency performance, time-resolved electroluminescence spectrum, and electric profile...etc. Also, this solver can be used to explain the mechanism of hyper-TTF OLEDs, and analysis the loss from different exciton mechanism. Furthermore, we can do further optimization for TTF-OLEDs to achieve an internal quantum efficiency increasing of 23% (from 29% to 36%).

Ruyi-Jinhuang Gao (RJG) is an ointment prepared from Ruyi-Jinhuang San (RJS), a traditional formula of powder-type Chinese medicine, usually used in anti-inflammatory analgesic care in China. The ...present study is aimed to detect the anti-inflammatory signaling of RJG exposed by an experimental model of lipopolysaccharides (LPS)-induced pro-inflammatory expression of inducible nitric oxide synthase (iNOS) and prostaglandin endoperoxide synthase (PGH synthase-2, COX-2). LPS-induced activation of iNOS and COX-2 has been recognized to increase cytokines and nitric oxide (NO), which play predominant roles in inflammation. In the culture of RAW264.7 cells, RJG concentration-dependently inhibited LPS-induced iNOS and COX-2 expression. However, the herbal components of RJG displayed different results, including increase and decrease of both protein expressions. Among them, inhibition by Curcuma Zedorarica Rhizoma (Cu), Atractylodis Lancea Rhizoma (At), and Glycyrrhizae Radix (Gl) are more potent than that by others.
