Published: September 2021

AbstractPolypropylene (PP) blends with acrylonitrile‐butadiene‐styrene (ABS) were prepared using the styrene‐ethylene‐butylene‐styrene copolymer (SEBS) as a compatibilizing agent. The blends were prepared in a co‐rotational twin‐screw extruder and injection molded. Torque rheometry, Izod impact strength, tensile strength, heat deflection temperature (HDT), differential scanning calorimetry, thermogravimetry, and scanning electron microscopy properties were investigated. The results showed that there was an increase in the torque of PA6/ABS blends with SEBS addition. The PP/ABS/SEBS (60/25/15%) blend showed significant improvement in impact strength, elongation at break, thermal stability, and HDT compared with neat PP. The elastic modulus and tensile strength have not been significantly reduced. The degree of crystallinity and the crystalline melting temperature increased, indicating a nucleating effect of ABS. The PP/ABS blends compatibilized with 12.5% and 15% SEBS presented morphology with well‐distributed fine ABS particles with good interfacial adhesion. As a result, thermal stability has been improved over pure PP and the mechanical properties have been increased, especially impact strength. In general, the addition of the SEBS copolymer as the PP/ABS blend compatibilizer has the advantage of refining the blend's morphology, increasing its toughness and thermal stability, without jeopardizing other PP properties.

AbstractThe biodegradable and naturally available wasteSyzygium cuminiparticulates filled E‐glass fiber laminate‐reinforced composites were fabricated with different weight percentages. The present work is to develop a new composite from huge waste ofS. cuminiseeds. The two different combinations of composites with different concentration (10, 20, 30, 40, and 50 wt%) of reinforcement were fabricated through open layup molding techniques. Functional groups, X‐ray diffraction, surface morphology, carbon, hydrogen, nitrogen and sulphur (CHNS) elemental analysis, and mechanical characteristics (tensile, flexural strength, and hardness) of fabricated composites were evaluated. The maximum tensile strength, flexural strength, and maximum Shore D hardness of the composite were found to be 14.04 ± 0.5 MPa, 1603 ± 0.5 MPa, and 92 ± 0.5 SHN, respectively. By incorporating E‐glass fiber laminate on both sides of theS. cuminiparticulates filled epoxy composite enhanced mechanical properties compared withS. cuminiparticulates filled epoxy composites. The results showed that these composites can be utilized as panels for low strength applications.

AbstractBackgroundRenin‐angiotensin‐aldosterone system inhibitors (RAASIs) are recommended for most patients with coronary artery disease (CAD). However, there is debate across guidelines as to which patients with CAD benefit the most from these agents. This study investigated the association between RAASIs and cardiovascular outcomes and acute kidney injury in a contemporary cohort of patients with CAD.MethodsPatients ≥65 years of age with CAD alive on April 1, 2012 in Ontario, Canada were included. Outcomes included major adverse cardiovascular events (MACE: cardiovascular death, myocardial infarction (MI), unstable angina, stroke, or coronary revascularization), and acute kidney injury (AKI) hospitalizations at 4 years. Inverse probability of treatment‐weighted Cox proportional hazards regression models was used to compare the rates of each outcome in patients treated with and without RAASIs (angiotensin‐converting enzyme inhibitors or angiotensin II receptor blockers).ResultsThere were 165,058 patients with CAD identified (mean age 75 years, 65.5% male, 64.7% prescribed RAASIs). After inverse‐probability weighting, treatment with RAASIs was associated with a lower rate of MACE compared with treatment without RAASIs (17.6% vs 18.2%, hazard ratio [HR]: 0.96, 95% CI: 0.93–0.99, respectively). However, treatment with RAASIs was associated with a higher rate of AKI compared with treatment without RAASIs (1.7% vs 1.5%, HR: 1.14, 95% CI: 1.02–1.29, respectively). The reduction in MACE was greater in patients with prior MI (HR: 0.87, 95% CI: 0.82–0.92) compared with patients without prior MI (HR: 1.00, 95% CI: 0.97–1.04, interaction p < 0.01). The increase in AKI was lower in patients with prior MI (HR: 0.82, 95% CI: 0.66–1.00) compared with patients without prior MI (HR: 1.37, 95% CI: 1.19–1.57, interaction p < 0.01).ConclusionsThis study supports the continued use of RAASIs in patients with CAD, although the benefit appears smaller in magnitude than observed in prior trials. High‐risk patients, particularly those with prior MI, appear to benefit the most from RAASIs.

Abstract‘AG18’ (Reg. no. CV‐147, PI 698186) is a high‐yielding, high‐grading, high‐oleic fatty acid, runner‐type peanut (Arachis hypogaea L. ssp. hypogaea var. hypogaea) cultivar with good resistance to Sclerotinia blight (caused by Sclerotinia minor Jagger). The cultivar was developed by the Texas A&M AgriLife Research peanut breeding program to provide growers with a higher‐yielding option when compared to the previously released ‘Tamrun OL11’ cultivar. AG18 was tested under the experimental designation of Tx121082 and was released in 2020. It maintains the high percentage of total sound mature kernels that Tamrun OL11 had, as well as the resistance to S. minor. However, it proved to have higher yield potential across environments and years than did Tamrun OL11. Additionally, the seed size of AG18 is smaller than that of Tamrun OL11 and closer to the past industry standard, ‘Florunner’, making it more attractive to manufacturers.

AbstractArkot 0912‐18 (Reg. no. GP‐1098, PI 697032) and Arkot 0912‐41 (Reg. no. GP‐1097, PI 697031) are conventional cotton (Gossypium hirsutum L.) germplasm lines released by the Arkansas Agricultural Experiment Station in December 2020. Both lines were derived from crossing ‘UA48’ and ‘UA222’. They produced higher lint yields than their parents over 5 yr and at four test sites in Arkansas. Both produced similar lint yields at each test site. Over test sites, the lines produced about 13 and 24% higher lint yields than UA222 and UA48, respectively. Arkot 0912‐18 produced the highest lint yield of all entries evaluated in the 2017 Regional Breeders Network Test. Over all locations of the 2017 Regional High Quality Test, lint yields of Arkot 0912‐41 ranked fourth out of 20 genotypes (second‐highest of 11 conventional genotypes) and equaled the lint yields of DP 1646 B2XF (U.S. patent no. 9,961,845) and PHY 444 WRF. Both lines produced higher lint percentage and lint index and were taller than either parent. Leaf pubescence, stem pubescence, and bract trichome density of each line exceeded both parents. Visual ratings of Verticillium wilt for Arkot 0912‐18 exceeded those of UA48. Both lines displayed high resistance to bacterial blight and were similar to UA222 and UA48 in their response to other diseases. The lines were more resistant to tarnished plant bug than UA48 but were more susceptible to tarnished plant bugs than UA222. Measurements of fiber quality for the two lines were intermediate between that of UA48 (excellent fiber quality) and UA222 (good fiber quality).

AbstractIdentifying the changes in thermokarst lake dynamics has a significant contribution to landscape‐scale hydrology, ecology, and assessment of carbon budgets in permafrost regions. Changes in the number and areal extent of thermokarst lakes and ponds were quantified in a representative permafrost area (150 km2) in the south‐central Headwater Area of the Yellow River (HAYR). Water‐body inventories were generated from Landsat satellite imageries using the supervised Maximum Likelihood Classification method for three periods: 1986, 2000, and 2015. From 1986 to 2015, the number of water bodies larger than 0.36 ha decreased by 40% (461–277), while the total surface area decreased by 25% (542–406 ha). The ponds category (smaller than 1 ha) recorded the most substantial change, as their number decreased by 44% and their water‐surface area by 41%. Many lakes disintegrated, partially drained, and formed several remnant ponds, while the majority of the ponds did not drain completely, but shrank below 0.36 ha. These shrinking patterns are consistent with the warming climate in the HAYR, which suggests intense permafrost degradation. Future research will be focused on a better understanding of water–heat dynamics of thermokarst lakes and ponds in association with permafrost degradation at a landscape scale.

Cervical cancer is the fourth leading cause of cancer mortality in women worldwide. Beetroot (Beta vulgaris L.) has bioactive compounds that can inhibit the progression of different types of cancer. To analyze the antiproliferative effects of beet leaf and root extracts, we performed MTT, clonogenic survival, cell cycle analysis, Annexin/PI labeling, and western blotting. Here, we report that 10 and 100 μg/ml of root and leaf extracts decreased cell viability and potentiated rapamycin and cisplatin effects while decreased the number of large colonies, especially at 10 μg/ml (293.6 of control vs. 200.0 of leaf extract, p = .0059; 138.6 of root extract, p = .0002). After 48 hr, 100 μg/ml of both extracts led to increased sub‐G1 and G0/G1 populations. In accordance, 100 μg/ml of root extract induced early apoptosis (mean = 0.64 control vs. 1.56 root; p = .048) and decreased cell size (p < .0001). Both extracts decreased phosphorylation and expression of mechanistic Target of Rapamycin (mTOR) signaling, especially by inhibiting ribosomal protein S6 (S6) phosphorylation, increasing cleaved poly(ADP‐ribose) polysomerase 1 (PARP1) and Bcl‐2‐like protein 11 (BIM), and decreasing cyclin D1 expression, which regulates cell cycle progression. Here, we demonstrate that beetroot and leaf extracts could be an efficient strategy against cervical cancer.

This study aimed to investigate the effect of nanomicelle curcumin (CUR), Nigella sativa oil (NS), and CUR and NS on the plasma levels of miR‐21, miR‐422a, and miR‐503 expression in postmenopausal women with low bone mass density (BMD). This randomized, triple‐blind, placebo‐controlled clinical trial with a factorial design was conducted on 120 postmenopausal women from the integrated healthcare system, Tabriz‐Iran. The BMD was determined using dual‐energy X‐ray absorptiometry (DEXA). Women were randomly divided into four groups of 30 participants: (a) CUR (80 mg) and placebo of NS, (b) NS (1,000 mg) and placebo of CUR, (c) CUR (80 mg) and NS (1,000 mg), and (d) both placebos (containing microcrystalline cellulose). The plasma level of miRNA‐21, miRNA‐422a, and miRNA‐503 was determined by qRT‐PCR. The expression level of miRNAs at the baseline was similar. At the end of the intervention, only the expression level of miRNA‐21 changed statistically significantly between the four groups (p = .037) and between the NS and placebo groups (p = .005). Also, its expression in the two groups receiving NS (p = .037) and NS–CUR (p = .043) was significantly increased. NS and NS–CUR supplementation can increase the expression level of miRNA‐21 in postmenopausal women with low bone density, and bring perspective to further studies of the target.

Published: September 2021

AbstractA coherent Ising machine (CIM) comprising a network of open‐dissipative quantum oscillators with optical error correction circuits is proposed. In the proposed network, the squeezed/anti‐squeezed vacuum states of the constituent optical parametric oscillators establish quantum correlations below the threshold through optical mutual coupling and collective symmetry breaking is induced above the threshold as a decision‐making process. This initial search process is followed by a chaotic solution search step facilitated by optical error correction feedback. The particular algorithm used by the proposed network is derived from the truncated Wigner stochastic differential equation. As an optical hardware technology, the proposed CIM has several unique features, including programmable all‐to‐all Ising coupling in the optical domain, directional coupling ()‐induced chaotic behavior, and the ability to operate at low power at room temperature. The proposed CIM is evaluated in terms of its performance and how this scales at different problem sizes. It is shown that the various CIMs discussed in this paper are effective at solving many problem types, although the optimal algorithm depends on the problem case. It is further shown that the proposed optical implementations can be achieved with low energy consumption on thin‐film LiNbO3 platforms.
Discrete‐time decentralized linear quadratic control for linear time‐varying systems
Authors: Pedroso Leonardo , Batista Pedro 
Published: September 2021

AbstractThis article addresses the problem of designing a decentralized control solution for a network of agents modeled by linear time‐varying (LTV) dynamics, in a discrete‐time framework. A general scheme is proposed, in which the problem is formulated as a classical linear quadratic regulator problem, for the global system, subject to a given sparsity constraint on the gain, which reflects the decentralized nature of the network. A method able to compute a sequence of well‐performing stabilizing regulator gains is presented and validated resorting to simulations of two randomly generated LTV systems, one stable and the other unstable. Moreover, a tracking solution is developed, building on the solution to the regulator problem. Both methods rely on a closed‐form solution, thus they can be computed very rapidly. Similarly to the centralized solution, both the presented methods require that a window of the future system dynamics is known. Both methods are validated resorting to simulations of: (i) a nonlinear network of four interconnected tanks; and (ii) a large‐scale nonlinear network of interconnected tanks. When implemented to a nonlinear network, approximated by an LTV system, the proposed methods are able to compute well‐performing gains that track the desired output. Finally, both algorithms are scalable, being adequate for implementation in large‐scale networks.

AbstractNitroarenes are versatile intermediate, thus found ubiquitous uses in synthesis of bio‐related molecules and functional materials. Herein we develop methods for synthesis of substituted nitroarenes benefited from oxidative nucleophilic amination of C−H bonds para to the nitro functionality. Simple base NaOH was used to mediate the coupling of N−H heterocycles and nitrobenzene. Meanwhile, 5‐nitro‐1‐aryl‐1H‐indazoles were isolated from copper‐mediated annulation of 3‐nitroaryl methyl ketones and arylhydrazines.

AbstractRechargeable lithium‐ion batteries have built much of our modern society. Developing high‐loading and high‐energy batteries have become an inevitable trend to satisfy the ever‐growing demand of energy consumption. However, issues related to mechanical instability and electrochemical polarization have become more prominent accompanying the increase of electrode thickness. How to establish a robust and rapid charge transport network within the electrode architecture plays a vital role for the mechanical property and the reaction dynamics of thick electrodes. In this review, principles of charge transport mechanism and challenges of thick electrode development are elaborated. Next, recent progress on advanced electrode architecture design focused on structural engineering is summarized. Finally, a transmission line model is proposed as an effective tool to guide the engineering of thick electrodes.

Published: September 2021

AbstractThe complexity inherent in the TESOL field can present challenges for Language Teacher Associations (LTAs) in undertaking internal‐facing roles such as professional learning including networking, conferences and publications, as well as external‐facing roles such as advocacy work with stakeholders, and curriculum reform, among other issues (e.g., Elsheikh & Effiong, 2018b; Lamb, 2012; Paran, 2016). LTAs must be cognizant of and responsive to changing socio‐political, policy, funding factors influencing TESOL provision, as well as the changing pedagogical needs of educators working across sectors. This study investigates the factors which influence and shape English as an Additional Language (EAL) education across a local (state based) EAL context and considers how these findings can inform the activities and practices of LTAs. Q methodology, which combines the use of qualitative and quantitative data, is employed to provide insights into current, deeply held perspectives of educators in relation to EAL provision. Findings provide insights into contextual variables which impact on EAL provision in adult education and school‐based contexts, including intensive English education for refugee and migrant children. This in turn provides an opportunity to consider implications of these findings for LTA activities and practices, in particular, in relation to professional learning, leadership and advocacy.

Published: September 2021

AbstractIntroductionDeclining cognition in later life is associated with loss of independence and quality of life. This decline in cognition may potentially be reduced or reversed through engaging in cognitively stimulating activities. This study examined the potential for university attendance in later life to enhance cognitive function in older adults.MethodsCognitively unimpaired adults (n = 485, 69% female, median age 60 years) were given the opportunity to undertake free university study. Repeated neurocognitive assessment was performed over 7 years.ResultsParticipants in the university education group (n = 383) improved z = .02 SD (.01, .03) per year of the study compared to controls (P = .001; averaged across a battery of cognitive tests). The largest improvements were observed on tests of language and verbal learning, memory, and episodic memory.DiscussionLater‐life university study was associated with improved cognitive trajectories. Later‐life education may preserve cognitive function, specifically for functions associated with communication, social interaction, and maintaining independence.
Plasticity in depth selection behavior and heat shock proteins in Daphnia
Authors: Bernatowicz Piotr , Dawidowicz Piotr , Pijanowska Joanna 
Published: September 2021

AbstractHabitat selection behavior by aquatic and terrestrial animals is influenced by both abiotic (e.g., temperature) and biotic (e.g., threat from predators) environmental factors. In this study, the mechanisms underlying the variability in behavior of habitat selection of Daphnia under environmental stress were examined. Experiments were conducted using five Daphnia clones with different environmental preferences and, consequently, with a different width of the reaction norm. These clones also showed variation in their constitutive levels of stress-related heat shock proteins (HSP60, HSP70 and HSP90), but none of the tested stress factors had any direct effect on their expression. However, behavioral plasticity was significantly positively correlated with the constitutive level of HSP70. It is likely that animals with a high constitutive HSP70 level can cope better with sudden changes in environment conditions that they experience, e.g., during vertical migrations. In contrast, non-migrating animals with low HSP levels do not allocate energy to the synthesis of stress proteins and have a narrow range of behavioral plasticity.
