Article Catalytic effects of zirconium on scratch-healing and mechanical properties of urethane–acrylate automotive clearcoat This work describes the effect of zirconium(IV) acetylacetonate (Zr(acac)4) on the self-healing and thermomechanical properties of urethane–acrylate copolymers, and which were compared with dibutyltin dilaurate (DBTDL). For prepolymer synthesis, glyceryl methacrylate (GlyMA) and 2-hydroxyethyl methacrylate (HEMA) were chosen and copolymerized with methyl methacrylate (MMA) and butyl acrylate (BA) at a concentration of 8 mol%. The prepolymers (G8 and H8) were then crosslinked with HDI trimer to prepare self-healing copolymers, and DBTDL or Zr(acac)4 was used as both crosslinking and self-healing catalysts. The self-healing performance of new carbonate bond formation by DBTDL and transesterification by Zr(acac)4 were studied and compared using single scratch test with atomic force microscopy (AFM). Owing to the secondary hydroxyl groups of GlyMA, DBTDL shows scratch-healing capability only in the GlyMA-based copolymer (G8) within 1 h at 55 and 75 °C. On the other hand, Zr(acac)4 shows scratch-healing capability in both copolymers (G8 and H8) within 1 h at 55 and 75 °C; however, transesterification may result in the changes of storage modulus and glass-transition temperature (Tg). This was confirmed from dynamic mechanical analysis (DMA) that a low temperature (∼55 °C) exhibited excellent self-healing performance with minimal hardness change by transesterification. © 2020 Elsevier B.V.

Article COVID-19 Transmission: Bangladesh Perspective The sudden emergence of the COVID-19 pandemic has tested the strength of the public health system of the most developed nations and created a "new normal". Many nations are struggling to curb the epidemic in spite of expanding testing facilities. In this study, we consider the case of Bangladesh, and fit a simple compartmental model holding a feature to distinguish between identified infected and infectious with time series data using least square fitting as well as the likelihood approach; prior to which, dynamics of the model were analyzed mathematically and the identifiability of the parameters has also been confirmed. The performance of the likelihood approach was found to be more promising and was used for further analysis. We performed fitting for different lengths of time intervals starting from the beginning of the outbreak, and examined the evolution of the key parameters from Bangladesh's perspective. In addition, we deduced profile likelihood and 95% confidence interval for each of the estimated parameters. Our study demonstrates that the parameters defining the infectious and quarantine rates change with time as a consequence of the change in lock-down strategies and expansion of testing facilities. As a result, the value of the basic reproduction number R0 was shown to be between 1.5 and 12. The analysis reveals that the projected time and amplitude of the peak vary following the change in infectious and quarantine rates obtained through different lock-down strategies and expansion of testing facilities. The identification rate determines whether the observed peak shows the true prevalence. We find that by restricting the spread through quick identification and quarantine, or by implementing lock-down to reduce overall contact rate, the peak could be delayed, and the amplitude of the peak could be reduced. Another novelty of this study is that the model presented here can infer the unidentified COVID cases besides estimating the officially confirmed COVID cases. Masud, M.

Article Effects of Subsequent Systemic Anticancer Medication Following First-Line Lenvatinib: A Post Hoc Responder Analysis from the Phase 3 REFLECT Study in Unresectable Hepatocellular Carcinoma Introduction: Understanding the relationship between subsequent-line therapies and overall survival (OS) is important for maximizing OS for patients with hepatocellular carcinoma. Objective: In this post hoc analysis, we investigated OS in lenvatinib- and sorafenib-treated patients from the REFLECT study, who then received subsequent anticancer medication during the survival follow-up period. Methods: The follow-up period commenced at the first off-treatment visit after stopping the study medication and continued until study termination, withdrawal of consent, or death. OS and objective response rate were calculated for patients who did or did not receive poststudy anticancer medication for both treatment arms, as well as for the overall cohort. We investigated the subset of patients who responded to first-line treatment and subsequently received anticancer medication. Results: The OS for patients initially randomized to first-line lenvatinib (versus first-line sorafenib) and who then received any subsequent anticancer medication was 20.8 vs. 17.0 months (hazard ratio [HR] 0.87; 95% CI 0.67-1.14). The OS for patients who initially received first-line lenvatinib (versus first-line sorafenib) and who did not receive any subsequent anticancer medication was 11.5 vs. 9.1 months (HR 0.90; 95% CI 0.75-1.09). Responders to first-line lenvatinib who received subsequent medication had a median OS of 25.7 months (95% CI 18.5-34.6); responders to first line-sorafenib who received subsequent medication had a median OS of 22.3 months (95% CI 14.6-not evaluable). Conclusions: In this post hoc analysis of all patients in the REFLECT study who received subsequent anticancer medication, OS was increased compared with patients who did not receive any subsequent anticancer medication. In a subset analysis of responders who had received subsequent anticancer medication, use of first-line lenvatinib led to a slightly longer median OS; more research is needed on the benefits of using first-line lenvatinib compared with sorafenib.

Article Estimation and Prediction of Record Values Using Pivotal Quantities and Copulas Recently, the area of sea ice is rapidly decreasing due to global warming, and since the Arctic sea ice has a great impact on climate change, interest in this is increasing very much all over the world. In fact, the area of sea ice reached a record low in September 2012 after satellite observations began in late 1979. In addition, in early 2018, the glacier on the northern coast of Greenland began to collapse. If we are interested in record values of sea ice area, modeling relationships of these values and predicting future record values can be a very important issue because the record values that consist of larger or smaller values than the preceding observations are very closely related to each other. The relationship between the record values can be modeled based on the pivotal quantity and canonical and drawable vine copulas, and the relationship is called a dependence structure. In addition, predictions for future record values can be solved in a very concise way based on the pivotal quantity. To accomplish that, this article proposes an approach to model the dependence structure between record values based on the canonical and drawable vine. To do this, unknown parameters of a probability distribution need to be estimated first, and the pivotal-based method is provided. In the pivotal-based estimation, a new algorithm to deal with a nuisance parameter is proposed. This method allows one to reduce computational complexity when constructing exact confidence intervals of functions with unknown parameters. This method not only reduces computational complexity when constructing exact confidence intervals of functions with unknown parameters, but is also very useful for obtaining the replicated data needed to model the dependence structure based on canonical and drawable vine. In addition, prediction methods for future record values are proposed with the pivotal quantity, and we compared them with a time series forecasting method in real data analysis. The validity of the proposed methods was examined through Monte Carlo simulations and analysis for Arctic sea ice data.

Article Highly conductive and thermally stable nanoparticle-conjugated polymer compounds through environmentally friendly in situ synthesis In this paper, an environmentally-friendly in situ synthesis of highly conducive and thermally stable nanoparticle-conjugated polymer nano-compounds is introduced. The water-based in situ chemical synthesis enables the successful polymerization of conducive, conjugated polypyrrole: polystyrene sulfonate (PPY:PSS) polymer and the incorporation of silver (Ag) nanoparticles without morphological deformation. The Ag nanoparticles dispersed within the PPY:PSS acted as a mass transport barrier, thus enhancing the thermal stability of the obtained Ag-PPY:PSS. In addition, the enhanced electrical conductivity of Ag-PPY:PSS was attributed to the embedded Ag nanoparticles generating a low-contact resistance conduction pathway, thereby facilitating interchain charge transport. Moreover, the conductivity of Ag-PPY:PSS was well tuned by controlling the weight percentage of Ag nanoparticles in the reaction mixture. The environmentally-friendly synthesis of highly conductive and thermally stable nano-compounds will contribute to the realization of next-generation green electronic applications.

Article In Situ-Generated Reactive Oxygen Species in Precharged Titania and Tungsten Trioxide Composite Catalyst Membrane Filters: Application to As(III) Oxidation in the Absence of Irradiation This study demonstrates that in situ-generated reactive oxygen species (ROSs) in prephotocharged TiO2 and WO3 (TW) composite particle-embedded inorganic membrane filters oxidize arsenite (As(III)) into arsenate (As(V)) without any auxiliary chemical oxidants under ambient conditions in the dark. TW membrane filters have been charged with UV or simulated sunlight and subsequently transferred to a once-through flow-type system. The charged TW filters can transfer the stored electrons to dissolved O-2, producing ROSs that mediate As(III) oxidation in the dark. Dramatic inhibition of As(V) production with O-2 removal or addition of ROS quenchers indicates an ROS-mediated As(III) oxidation mechanism. Electron paramagnetic spectroscopic analysis has confirmed the formation of the HO2 center dot-/O-2(center dot-) pair in the dark. The WO3 fraction in the TW filter significantly influences the performance of the As(III) oxidation, while As(V) production is enhanced with increasing charging time and solution pH. The As(III) oxidation is terminated when the singly charged TW filter is fully discharged; however, recharging of TW recovers the catalytic activity for As(III) oxidation. The proposed oxidation process using charged TW membrane filters is practical and environmentally benign for the continuous treatment of As(III)-contaminated water during periods of unavailability of sunlight.

Article Integral Domains in Which Every Nonzero w-Flat Ideal Is w-Invertible Let D be an integral domain and w be the so-called w-operation on D. We define D to be a w-FF domain if every w-flat w-ideal of D is of w-finite type. This paper presents some properties of w-FF domains and related domains. Among other things, we study the w-FF property in the polynomial extension, the t-Nagata ring and the pullback construction.

Article Nitrogen Stimulates Microcystis-Dominated Blooms More than Phosphorus in River Conditions That Favor Non-Nitrogen-Fixing Genera Despite the implementation of intensive phosphorus reduction measures, periodic outbreaks of cyanobacterial blooms in large rivers remain a problem in Korea, raising the need for more effective solutions to reduce their occurrence. This study sought to evaluate whether phosphorus or nitrogen limitation is an effective approach to control cyanobacterial (Microcystis) blooms in river conditions that favor this non-nitrogen-fixing genus. These conditions include nutrient enrichment, high water temperature, and thermal stratification during summer. Mesocosm bioassays were conducted to investigate the limiting factors for cyanobacterial blooms in a river reach where severe Microcystis blooms occur annually. We evaluated the effect of five different nitrogen (3, 6, 9, 12, and 15 mg/L) and phosphorus 0.01, 0.02, 0.05, 0.1, and 0.2 mg/L) concentrations on algae growth. The results indicate that nitrogen treatments stimulated cyanobacteria (mostly Microcystis aeruginosa) more than phosphorus. Interestingly, phosphorus additions did not stimulate cyanobacteria, although it did stimulate Chlorophyceae and Bacillariophyceae. We conclude that phosphorus reduction might have suppressed the growth of Chlorophyceae and Bacillariophyceae more than that of cyanobacteria; therefore, nitrogen or at least both nitrogen and phosphorus control appears more effective than phosphorus reductions alone for reducing cyanobacteria in river conditions that are favorable for non-nitrogen-fixing genera.
