Abstract‘L 11‐183’ (Reg. no. CV‐200, PI 698200) sugarcane (interspecific hybrid of Saccharum spp.) was derived from a cross between HoCP 92‐624 as the female and ‘LCP 85‐384’ as the male parent. Early‐stage clonal selection by researchers at the Louisiana State University Agricultural Center led to the assignment of a permanent cultivar number in 2011. The cultivar was further evaluated cooperatively with scientists from the USDA–ARS and the American Sugar Cane League. L 11‐183 was jointly released to the Louisiana sugar industry on 11 May 2018. L 11‐183 was released because of its high yield potential compared with ‘HoCP 96‐540’ and ‘L 01‐299’, two of the most widely grown cultivars in Louisiana at the time. In the final testing stage, data were collected from across 12 locations and three crops (plant cane and first and second ratoons) with multiple crop‐years within locations. Combined across locations and crops, L 11‐183 accumulated 5% more cane yield than HoCP 96‐540 but 4% less than L 01‐299. Sucrose yield in L 11‐183 was comparable to that of L 01‐299 but 3% greater than that of HoCP 96‐540. The new cultivar is resistant to smut, moderately resistant to leaf scald, Sugarcane yellow leaf virus, and ratoon stunting, moderately susceptible to brown rust and Sugarcane mosaic virus, and susceptible to the sugarcane borer.

AbstractNo sunlight can reach the hadal trench, but some fishes dwelling there still have apparent eye morphology. However, whether they are capable of sensing light remains unknown. In this study, the eyes of the dominant hadal endemic snailfish Pseudoliparis swirei from the Mariana Trench were analyzed using liquid chromatography–mass spectrometry/mass spectrometry (LC‐MS/MS). A total of 2088 proteins were identified in the eye proteome, most of which had at least one hit against public databases and could be mapped to 316 metabolic pathways. Gene Ontology (GO) terms and Kyoto Encyclopedia of Genes and Genomes (KEGG) pathways directly contributing to visual phototransduction were significantly enriched from the top 10% dominant proteins, implying abundant metabolic activities in the eye and it is still a functional visual organ. One rhodopsin was identified in the eye proteome, sequence analysis indicated that it might have an absorption maximum at ∼480 nm and be sensitive to dim blue light. In addition, proteins that might contribute to extreme environment adaptation, such as heat shock proteins and chaperonin‐containing T‑complex protein 1, were also highly expressed in the eye. Overall, these results provide insights into the molecular mechanism underlying the vision of hadal snailfish and provide a useful database for further research.

AbstractBACKGROUNDThis study evaluated the potential ofNeoseiulus cucumerisOudemans andAmblyseius swirskiiAthias‐Henriot (Acari: Phytoseiidae) for controlling western flower thrips (WFT),Frankliniella occidentalis(Pergande) (Thysanoptera: Thripidae), by determining the functional response, numerical response, prey switching and mutual interference behaviors of the predators.RESULTSA type II functional response was detected for two predator species fed on WFT first instars. The attack rate was higher forA. swirskiithanN. cucumeris, but the handling time ofN. cucumeriswas shorter. For two predator species, numerical response was affected by both prey density and oviposition time. Theper capitasearching efficiencies of the two predators decreased significantly with increasing predator densities. The interference coefficient forA. swirskiiwas less than that ofN. cucumeris. AlthoughN. cucumerisswitched from feeding on WFT first instars to feeding on second instars, this behavior was not observed inA. swirskii.CONCLUSIONSComparison of the two predator species foraging behaviors indicated optimal performance byA. swirskiiat lowerF. occidentalisdensities.N. cucumeriswas found to perform optimally at relatively higher prey densities. Moreover,N. cucumeriscould be more effective in stabilizing the predator–prey system by switching behavior compared withA. swirskii. At higher predator densities,A. swirskiiseemed to be an effective agent owing to its reduced intraspecific competition compared withN. cucumeris. Findings from this study will be useful in selecting appropriate agents and developing effective biocontrol programs to control WFT. © 2021 Society of Chemical Industry.
Robust adaptive model predictive control for guaranteed fast and accurate stabilization in the presence of model errors
Authors: Pereida Karime , Brunke Lukas , Schoellig Angela P. 
Published: July 2021

AbstractNumerous control applications, including robotic systems such as unmanned aerial vehicles or assistive robots, are expected to guarantee high performance despite being deployed in unknown and dynamic environments where they are subject to disturbances, unmodeled dynamics, and parametric uncertainties. The fast feedback of adaptive controllers makes them an effective approach for compensating for disturbances and unmodeled dynamics, but adaptive controllers seldom achieve high performance, nor do they guarantee state and input constraint satisfaction. In this article we propose a robust adaptive model predictive controller for guaranteed fast and accurate stabilization in the presence of model uncertainties. The proposed approach combines robust model predictive control (RMPC) with an underlying discrete‐time adaptive controller. We refer to this combined controller as an RMPC‐ controller. The adaptive controller forces the system to behave close to a linear reference model despite the presence of parametric uncertainties. However, the true dynamics of the adaptive controlled system may deviate from the linear reference model. In this work we prove that this deviation is bounded and use it as the modeling error of the linear reference model. We combine adaptive control with an RMPC that leverages the linear reference model and the modeling error. We prove stability and recursive feasibility of the proposed RMPC‐. Furthermore, we validate the feasibility, performance, and accuracy of the proposed RMPC‐ on a stabilization task in a numerical experiment. We demonstrate that the proposed RMPC‐ outperforms adaptive control, robust MPC, and other baseline controllers in all metrics.
“What’s Blackness Got to Do With All This?”: Racializing Literacy Assemblages
Authors: Guerrero‐Arias Beatriz Eugenia 
Published: July 2021

ABSTRACTThis is a qualitative case study about the literacy practices of a Black family living in an urban context in Cali, Colombia. I analyzed the interaction between a Black family and social institutions, as mediated by literacies that assemble racial processes and family configurations. I collected data about the family in the settings in which the seven family members participated. Drawing from Black feminist/critical theories, I analyzed how this Black family’s configuration and functioning link to a particular view of literacies, how those literacies are interwoven in practice with racial processes, and how such a weave is knitted through interaction with social institutions. The findings suggest that this Black family assembles family and race with literacy formations that are collective, multimodal, organic, aesthetically based, emotional, embodied, and performed. These assemblages have no structural space because they are out of the system of what Man has typically defined as official literacy, ideal race, and expected family functioning. Nevertheless, the family creates a wide assemblage repertoire for collaborative ways of living aimed at validating Black humanhood. These racializing literacy assemblages are, then, liberatory formations that reaffirm Black people’s pasts, presents, futures, and hopes.
Determination of Polylactide Microstructure by Homonuclear Decoupled 1H NMR Spectroscopy
Authors: Singha Roy Sourav , Sarkar Sriparna , Chakraborty Debashis 
Published: July 2021

AbstractThe ring‐opening polymerization (ROP) of lactide (the dilactone of lactic acid) produces poly(lactide) commonly referred to as poly(lactic acid) (PLA). The monomer lactide, has two stereogenic centers and thus, three stereoisomers are possible, namely: D‐(R,R), L‐(S,S) and meso‐lactide. The rac‐lactide is an equimolar mixture of D‐ and L‐enantiomers. Depending upon the relative configuration of the stereogenic centers in the polymeric chain, different tacticities (isotactic, syndiotactic, heterotactic and atactic) arise in the PLA chains. The study of the tacticity of a polymer is fundamental since it plays a crucial role in determining the physical properties of the polymer. NMR spectroscopy is a powerful analytical technique for the determination of the tacticity of PLA. This article describes in details the tacticity assignment for PLA derived from ROP of rac‐lactide and meso‐lactide, using homonuclear proton‐decoupled 1H NMR. The detailed tetrad level assignment pertinent to the methine hydrogen signal is the key for the determination of tacticity.

AbstractHoffmann's two‐toed sloths (Choloepus hoffmanni) are unique animals popular in zoological settings. The role of vitamin D in the maintenance of calcium homeostasis in this species is unexplored, although disorders of calcium homeostasis have been reported in managed sloths, including urolithiasis and soft tissue mineralization. This study assessed cutaneous concentrations of 7‐dehydrocholesterol (7‐DHC) in nine indoor‐housed Hoffmann's two‐toed sloths, as a means of evaluating the potential for cutaneous photobiosynthesis of vitamin D3. Samples were obtained from both abdominal and lumbar regions of the skin to assess for regional variation in 7‐DHC concentration. The average concentration of 7‐DHC in the sloth skin was low (0.197 ± 0.02 nmol/cm2). Location had a significant effect on 7‐DHC level only when concentrations were expressed based on the wet weight of the sample (ng/g), but levels were similar when values were normalized to biopsy surface area (nmol/cm2).
Killing superalgebras for lorentzian five-manifolds
Authors: Beckett Andrew , Figueroa-O’Farrill José 
Published: July 2021

Abstract
We calculate the relevant Spencer cohomology of the minimal Poincaré superalgebra in 5 spacetime dimensions and use it to define Killing spinors via a connection on the spinor bundle of a 5-dimensional lorentzian spin manifold. We give a definition of bosonic backgrounds in terms of this data. By imposing constraints on the curvature of the spinor connection, we recover the field equations of minimal (ungauged) 5-dimensional supergravity, but also find a set of field equations for an $$ \mathfrak{sp} $$
sp
(1)-valued one-form which we interpret as the bosonic data of a class of rigid supersymmetric theories on curved backgrounds. We define the Killing superalgebra of bosonic backgrounds and show that their existence is implied by the field equations. The maximally supersymmetric backgrounds are characterised and their Killing superalgebras are explicitly described as filtered deformations of the Poincaré superalgebra.
Twisted D3-brane and M5-brane compactifications from multi-charge spindles
Authors: Boido Andrea , Ipiña Juan Manuel Pérez , Sparks James 
Published: July 2021

Abstract
We construct families of supersymmetric AdS3 × Y7 and AdS3 × Y8 solutions to type IIB string theory and M-theory, respectively. Here Y7 is an S5 fibration over Σ, while Y8 is an S4 fibration over Σg × Σ, where Σg is a Riemann surface of genus g > 1 and Σ is a two-dimensional orbifold known as a spindle. We interpret the solutions as near-horizon limits of N D3-branes wrapped on Σ and N M5-branes wrapped on Σg × Σ, respectively. These are holographically dual to d = 2, (0, 2) SCFTs, and we show that the central charge and superconformal R-symmetry of the gravity solutions agree with dual field theory calculations.

Use of bioluminescence measurements for detection of artificial demineralization adjacent to orthodontic brackets
Authors: Jablonski-Momeni Anahita , Sambale Janine , Gaerttner Laura , Nothelfer Romy , Korbmacher-Steiner Heike 
Published: July 2021

Abstract
Purpose
Enamel demineralization can occur as a side effect during orthodontic treatment with fixed appliances and should be detected as early as possible. A new approach to assess demineralization is a system consisting of a photosensitive protein that binds to free calcium ions at the enamel surface. A camera is then used to visualize the bioluminescence spots. This in vitro study aimed to evaluate the ability of the bioluminescence technology to assess artificially demineralized enamel adjacent to various orthodontic brackets.

Methods
In all, 108 human enamel samples were allocated randomly to groups with different orthodontic bracket material: stainless steel, titanium, ceramic. Initial lesions were created adjacent to the brackets. The samples were assessed by bioluminescence before and after demineralization. Images were assessed for presence of bioluminescence spots (yes/no). To quantify the bioluminescence measurements, the images’ pixel values (P) were calculated within a defined area (F) adjacent to each bracket before and after demineralization. Quantitative light-induced fluorescence measurements (ΔF, ΔQ) were performed as the reference standard for demineralization.

Results
After demineralization, bioluminescence spots were visible (yes/no decision) in 87% of the samples. The pixel analysis of the bioluminescence spots showed significantly higher pixel values after demineralization compared to baseline (p < 0.0001). The bracket material had no influence on the bioluminescence measurements. All samples showed fluorescence loss with a median ΔF of −9.52% (±3.15) and a median ΔQ of −1.01% × mm2 (±3.34), respectively.

Conclusion
The bioluminescence technology is a promising tool to demonstrate demineralization adjacent to different orthodontic brackets in vitro.
Design of adaptive structures through energy minimization: extension to tensegrity
Authors: Wang Yafeng , Senatore Gennaro 
Published: July 2021

AbstractThis paper gives a new formulation to design adaptive structures through total energy optimization (TEO). This methodology enables the design of truss as well as tensegrity configurations that are equipped with linear actuators to counteract the effect of loading through active control. The design criterion is whole-life energy minimization which comprises an embodied part in the material and an operational part for structural adaptation during service. The embodied energy is minimized through simultaneous optimization of element sizing and actuator placement, which is formulated as a mixed-integer nonlinear programming problem. Optimization variables include element cross-sectional areas, actuator positions, element forces, and node displacements. For tensegrity configurations, the actuators are not only employed to counteract the effect of loading but also to apply appropriate prestress which is included in the optimization variables. Actuator commands during service are obtained through minimization of the operational energy that is required to control the state of the structure within required limits, which is formulated as a nonlinear programming problem. Embodied and operational energy minimization problems are nested within a univariate optimization process that minimizes the structure’s whole-life energy (embodied + operational). TEO has been applied to design a roof and a high-rise adaptive tensegrity structure. The adaptive tensegrity solutions are benchmarked with equivalent passive tensegrity as well as adaptive truss solutions, which are also designed through TEO. Results have shown that since cables can be kept in tension through active control, adaptive tensegrity structures require low prestress, which in turn reduces mass, embodied energy, and construction costs compared to passive tensegrity structures. However, while adaptive truss solutions achieve significant mass and energy savings compared to passive solutions, adaptive tensegrity solutions are not efficient configurations in whole-life energy cost terms. Since cable elements must be kept in tension, significant operational energy is required to maintain stable equilibrium for adaptation to loading. Generally, adaptive tensegrity solutions are not as efficient as their equivalent adaptive truss configurations in mass and energy cost terms.
Multiphysics modelling of the mechanical properties in polymers obtained via photo-induced polymerization

Published: July 2021

AbstractPhotopolymerization is an advanced technology to trigger free radical polymerization in a liquid monomer solution through light-induced curing, during which mechanical properties of the material are significantly transformed. Widely used in additive manufacturing, parts fabricated with this technique display precisions up to the nanoscale; however, the performance of final components is not only affected by the raw material but also by the specific setup employed during the printing process. In this paper, we develop a multiphysics model to predict the mechanical properties of the photo-cured components, by taking into account the process parameters involved in the considered additive manufacturing technology. In the approach proposed, the main chemical, physical, and mechanical aspects of photopolymerization are modelled and implemented in a finite element framework. Specifically, the kinetics of light diffusion from a moving source and chain formation in the liquid monomer is coupled to a statistical approach to describe the mechanical properties as a function of the degree of cure. Several parametric examples are provided, in order to quantify the effects of the printing settings on the spatial distribution of the final properties in the component. The proposed approach provides a tool to predict the mechanical features of additively manufactured parts, which designers can adopt to optimize the desired characteristics of the products.
Echo Chains as a Linear Mechanism: Norm Inflation, Modified Exponents and Asymptotics
Authors: Deng Yu , Zillinger Christian 
Published: July 2021

AbstractIn this article we show that the Euler equations, when linearized around a low frequency perturbation to Couette flow, exhibit norm inflation in Gevrey-type spaces as time tends to infinity. Thus, echo chains are shown to be a (secondary) linear instability mechanism. Furthermore, we develop a more precise analysis of cancellations in the resonance mechanism, which yields a modified exponent in the high frequency regime. This allows us, in addition, to remove a logarithmic constraint on the perturbations present in prior works by Bedrossian, Deng and Masmoudi, and to construct solutions which are initially in a Gevrey class for which the velocity asymptotically converges in Sobolev regularity but diverges in Gevrey regularity.
