Authors: Qaiser Nadeem , Damdam Asrar Nabil , Khan Sherjeel Munsif , Bunaiyan Saleh , Hussain Muhammad Mustafa 
Published: October 2020

AbstractStretchable electronics can be used for numerous advanced applications such as soft and wearable actuators, sensors, bio‐implantable devices, and surgical tools because of their ability to conform to curvilinear surfaces, including human skin. The efficacy of these devices depends on the development of stretchable geometries such as interconnection‐based configurations and the associated mechanics that helps to achieve optimum configurations. This work presents the essential mechanics of silicon (Si) island‐interconnection structures, which include horseshoe and spiral interconnections, without reducing the areal efficiency. In particular, this study demonstrates the range of the geometrical parameters where they have a high stretchability and cyclic life. The numerical results predict the areas that are prone to breaking followed by experimental validation. The figure‐of‐merit for these configurations is achieved by mapping the fracture‐free zones for in‐plane and out‐of‐plane stretching with essential implications in stretchable and wearable system design. Furthermore, this work demonstrates the mechanical response for a range of materials (i.e., copper, gold, aluminum, silver, and graphene) that experience the plastic deformations in contrast to conventionally used Si‐based devices that represent the extended usage for advanced stretchable electronic devices. The detailed mechanics of these configurations provides comprehensive guidelines to manufacture wearable and stretchable electronic devices.

Published: October 2020

AbstractMicrorobots for targeted drug delivery are of great interest due to their minimal invasiveness and wireless controllability. Here, a magnetically driven porous degradable microrobot (PDM) is reported that consists of a 3D printed helical soft polymeric chassis made of a poly(ethylene glycol) diacrylate and pentaerythritol triacrylate matrix containing magnetite nanoparticles and the anticancer drug 5‐fluorouracil (5‐FU). The encapsulated Fe3O4 nanoparticles render the PDM a precise wireless magnetic actuation by means of rotating magnetic fields (RMFs). The increased surface area of the porous PDM facilitates the acoustically induced drug release due to a higher response to the acoustic energy. The drug release profile from the PDM can be selected on command from three different modes, referred to herein as natural, burst, and constant, by differentiating the ultrasound exposure condition. Finally, in vitro test results reveal different therapeutic results for each release mode. The observed great reduction of cancer cell viability in the burst‐ and constant‐release modes confirms that ultrasound with the proposed PDM can enhance the therapeutic effect by increasing drug concentration and sonoporation.
Tunable Ultra‐High Q‐Factor and Figure of Merit based on Fano Resonance in Graphene–Dielectric Multilayer Corrugated Structure
Authors: Jiang Xiangqian , Liu Weiwei , Zhang Bing , Sun Xiudong 
Published: October 2020

AbstractHigh‐performance sensors have been a focus of the nanophotonics in recent years owing to their great potential for use in medical diagnosis and environmental remediation. Particularly, the sensing properties based on graphene have attracted intensive interest. Yet, low quality‐factor (Q‐factor) and figure of merit (FOM) have limited significant device performance. Here, a graphene–dielectric–graphene corrugated structure is proposed, the simulations show that by introducing the graphene the Q‐factor becomes tunable and can be significantly improved. The transmission and reflection spectra exhibit asymmetric Fano resonance with ultra‐narrow width that depends on the Fermi energy and modulation amplitude. Based on the high Q‐factor of the structure, the sensing properties of the structure are exploited when introducing sensing medium. For the shallow grating modulation, ultra‐high FOM is obtained. The proposed structure based on graphene has a promising potential for designing and fabricating novel refractive index sensors.

Published: October 2020

AbstractWith rapid advances in material synthesis and device performance, the long‐term stability of organic solar cells has become the main remaining challenge toward commercialization. An investigation of photodegradation in blend films of the donor polymer poly(3‐hexylthiophene) (P3HT) and the rhodanine‐flanked small molecule acceptor 5,5′‐[(9,9‐dioctyl‐9H‐fluorene‐2,7‐diyl)bis(2,1,3‐benzothiadiazole‐7,4‐diylmethylidyne)]bis[3‐ethyl‐2‐thioxo‐4‐thiazolidinone] (FBR) is presented in an ambient atmosphere. The photobleaching kinetics of the pure materials and their blends is correlated with the generation of radicals and triplet excitons using optical and magnetic resonance techniques. In addition, spin‐trapping methods are employed to identify reactive oxygen species (ROS). In films of P3HT, FBR, and the P3HT:FBR blend, superoxide is generated by electron transfer to molecular oxygen. However, it is found that the generation of singlet oxygen by energy transfer from the FBR triplet state is responsible for the poor stability of FBR and for the accelerated photodegradation at later times of the P3HT:FBR blend. In the early stage of degradation of the neat blend, it is protected from singlet oxygen by the fast donor–acceptor charge transfer, which competes with triplet exciton formation. These results provide initial input for a rational design of donor and acceptor materials through tuning the molecular singlet and triplet energy levels to prevent ROS‐related photodegradation.
How Has the COVID‐19 Pandemic Affected Outdoor Recreation in the U.S.? A Revealed Preference Approach
Authors: Landry Craig E. , Bergstrom John , Salazar John , Turner Dylan 
Published: October 2020

AbstractThis study examines the effects of the COVID‐19 pandemic on outdoor recreation trips and values using revealed preference data in the context of travel cost method. Demand models are estimated using data on pre‐ and postpandemic trips reported in a nationwide survey of recreation participants. The models incorporate related subjective risk perceptions as postpandemic measures of site quality and account for household‐level factors, pre‐existing conditions, and risk tolerance. Our results suggest that the pandemic had negative effects on recreation visits and values, with risk‐tolerant households and households with pre‐existing conditions taking more trips.

Published: October 2020

AbstractValorization of the agri‐food industry by‐products could contribute to curb issues related to food security and environmental problems. Flax and wheat seeds are major products of this industry, but their production is associated with tons of straws that can be valorized for their cuticular and epicuticular waxes. We aimed to determine the organogelation capacity of epicuticular waxes in comparison to cuticular waxes from both flax and wheat straws. Epicuticular waxes from flax and wheat straws have structured canola oil at 2% and 4% (w/w), respectively, whereas cuticular waxes from flax and wheat straws required critical concentrations of 4% and 5% (w/w), respectively. Characterization of the organogelation capacity (onset of crystallization temperature, temperature of phase transition, crystal morphology, solid fat, crystalline structure, and oil binding capacity) was also carried out. The high onset of crystallization temperature (38.1 ± 1.2°C), the phase transition at high temperature (38 ± 1.5°C), and capacity to structure canola oil at low concentration showed that epicuticular wax from flax straw is a promisor fat substitute, presenting organogelation properties comparable to the best results obtained in the literature for other vegetal waxes.

Published: October 2020

AbstractNematic monodomain liquid crystal elastomers (LCEs) undergo efficient temperature‐induced reversible shape‐shifting around the nematic‐isotropic transition temperature (Tni) due to the presence of the liquid‐crystalline order of mesogens. Usually, the Tni of nematic LCEs is much higher than the human body temperature, and therefore LCEs are not often considered for biomedical applications. This study describes an LCE system where the Tni is tuned by substitution of the rigid mesogens RM257 with a flexible backbone PEGDA250. By systematically substituting the RM257 with PEGDA250, the Tni of LCEs was observed to decrease from 66°C to 23°C. A rate‐optimized LCE material was fabricated with 10 mol % rigid mesogens substituted with a flexible backbone that demonstrated Tni at 32°C, in‐between the room temperature of 20°C and the body temperature of 37°C. The Tni allowed the programmed shape at room temperature, quick shape‐shifting upon exposure to body temperature, and before‐programmed shape when kept at body temperature. This LCE material displayed reversible length change of 23%, opacity change, and shape change between room temperature and body temperature.

Published: October 2020

AbstractIn order to investigate the influence of phenyl group number on enantioseparation capability of a chitosan‐based chiral selector (CS), in this study, two series of chitosan derivative and their enantioseparation were presented. According to the functional group at 2‐position of glucosamine, the derivatives were classified as amido‐type and ureido‐type. In the amido‐type CSs, the CS with two phenyl groups showed the best enantioseparation capability; the CS with one phenyl group exhibited the poorest enantioseparation; and the enantioseparation performance of the CS with three phenyl groups intermediated between those of the CSs with one and two phenyl groups. In the ureido‐type, the CS bearing three phenyl groups was in the middle of two CSs with two phenyl groups in enantioseparation capability. Based on the results obtained in the present study, one phenyl group in a chitosan derivative is not enough for enantioseparation, and two or three phenyl groups are necessary. On the other hand, introducing three phenyl groups onto one glucosamine unit of chitosan, can not definitely result in a better enantioseparation capability, comparing with introducing two phenyl groups.

Published: October 2020

AbstractRegulating the reactivity and equilibrium of a dynamic reaction is essential for adaptive chemistry and functional materials. Herein, cucurbituril‐based host‐guest interaction was embedded into the dynamic metathesis between diselenide and ditelluride to establish an equilibrium‐adaptive system. In this system, cucurbit[6]uril (CB[6]) selectively bound with diselenide while cucurbit[7]uril (CB[7]) bound with not only diselenide but also ditelluride and exchange product. The dynamic nature of diselenide bond was locked after forming the inclusion complex with CB[6]. Based on this selective locking effect, the Se−Te products were reversed back to diselenide and ditelluride reactants, which was an equilibrium regulating process. Therefore, by combining CB[6]‐based host‐guest interaction and dynamic diselenide chemistry, the reactivity of diselenide bond and the equilibrium of Se−Te metathesis was successfully regulated.

AbstractThe bilateral symmetric anterior shoulder dislocations (BSASD) must be suspected in patients with bilaterally flattened shoulders after an uncontrolled muscular contraction like seizure condition. BSASD is best managed acutely and challenging to manage when diagnosed late. Chronic BSASD, after two years in a young patient, can result in fair functions.

Published: October 2020

BackgroundThis is the largest and only multivariate study evaluating the difference in mortality from coronavirus disease 2019 (COVID‐19) between patients with cancer and patients without cancer in the United States. The objective was to assess COVID‐19 mortality rates in patients with cancer versus patients without cancer and uncover possible statistically significant characteristics contributing to mortality.MethodsThis retrospective study analyzed patients with cancer and patients without cancer who tested positive for severe acute respiratory syndrome coronavirus 2 (SARS‐CoV‐2) from March 1 through April 30, 2020. This was a multicenter study in the state of Louisiana throughout the Ochsner Health System in both tertiary and nontertiary centers. Patients older than 18 years were eligible. Three hundred twelve patients with cancer were compared with 4833 patients without cancer.ResultsMortality was found to be higher in the cancer group. Patients of advanced age with cancer had a significant increase in mortality (odds ratio [OR], 5.96; P < .001). Other significant risk factors for increased mortality were male sex (OR, 2.15), a history of chronic kidney disease (OR, 3.84), and obesity (OR, 1.30). In hospitalized patients with cancer, adverse vital signs on admission, decreased absolute lymphocyte counts, thrombocytopenia, elevated creatinine, lactic acidosis, and elevated procalcitonin all seemed to increase the risk of death. Among patients with cancer, active or progressive disease (P < .001) and recent therapy (OR, 2.34; 95% confidence interval, 1.08‐5.08) were shown to increase mortality.ConclusionsPatients with cancer have increased mortality in the setting of infection with SARS‐CoV‐2 in comparison with patients without cancer. Patients with cancer who are 65 years of age or older and those with certain comorbidities have the greatest risk of death. Recent cancer‐directed therapy and disease status also seem to play roles in mortality.Lay Summary

This is the largest study of patients with cancer versus patients without cancer to date and is the first multivariate analysis study comparing these 2 patient populations.

This study confirms the hypothesis that patients with cancer are at increased risk for mortality and that there are multiple characteristics posing the potential to risk‐stratify these patients in the setting of a future outbreak.

AbstractMolecularly imprinted polymers (MIPs) have been widely used for the modification of electrodes because of their native specificity for the intrinsic template molecules. The importance of catecholamines in the neurological and general well‐being of every individual cannot be overemphasized. Disorders associated with the imbalance in catecholamine levels can be diagnosed with electrochemical sensors capable of their determination in the presence of other biological interferents in extracellular fluids. MIPs based sensors have been designed for selective and simultaneous determination of these catecholamines in the past decade. Efforts in this regard and details on the components and preparation of these MIPs were presented in this review.
Deep neuro‐fuzzy approach for risk and severity prediction using recommendation systems in connected health care
Authors: Sharma Deepika , Singh Aujla Gagangeet , Bajaj Rohit 
Published: October 2020

AbstractInternet of Things (IoT) and Data science have revolutionized the entire technological landscape across the globe. Because of it, the health care ecosystems are adopting the cutting‐edge technologies to provide assistive and personalized care to the patients. But, this vision is incomplete without the adoption of data‐focused mechanisms (like machine learning, big data analytics) that can act as enablers to provide early detection and treatment of patients even without admission in the hospitals. Recently, there has been an increasing trend of providing assistive recommendation and timely alerts regarding the severity of the disease to the patients. Even, remote monitoring of the present day health situation of the patient is possible these days though the analysis of the data generated using IoT devices by doctors. Motivated from these facts, we design a health care recommendation system that provides a multilevel decision‐making related to the risk and severity of the patient diseases. The proposed systems use an all‐disease classification mechanism based on convolutional neural networks to segregate different diseases on the basis of the vital parameters of a patient. After classification, a fuzzy inference system is used to compute the risk levels for the patients. In the last step, based on the information provided by the risk analysis, the patients are provided with the potential recommendation about the severity staging of the associated diseases for timely and suitable treatment. The proposed work has been evaluated using different datasets related to the diseases and the outcomes seem to be promising.
Unconditionally energy stable, splitting schemes for magnetohydrodynamic equations
Authors: Wang Kun , Zhang Guo‐Dong 
Published: October 2020

AbstractIn this article, we propose first‐order and second‐order linear, unconditionally energy stable, splitting schemes for solving the magnetohydrodynamics (MHD) system. These schemes are based on the projection method for Navier–Stokes equations and implicit–explicit treatments for nonlinear coupling terms. We transform a double saddle points problem into a set of elliptic type problems to solve the MHD system. Our schemes are efficient, easy to implement, and stable. We further prove that time semidiscrete schemes and fully discrete schemes are unconditionally energy stable. Various numerical experiments, including Hartmann flow and lid‐driven cavity problems, are implemented to demonstrate the stability and the accuracy of our schemes.

Published: October 2020

AbstractDouchi, a popular traditional fermented soybean product, is mainly made by natural fermentation. However, its taste quality is affected by specific fungal communities which vary greatly according to fermentation conditions and production technologies used in different regions. Therefore, the taste quality of Douchi samples from different regions was digitally evaluated using electronic tongue technology. In addition, the fungal community structures and its association of them were also identified using high‐throughput sequencing technology. Results showed that there were obvious differences in the taste quality of samples from different regions, while the tastes of different types of samples from the same region were similar. Sourness, umami, richness, and saltiness were the main reasons for regional differences in taste. Similarly, the results of high‐throughput sequencing indicated that samples from different regions displayed important differences in dominant fungal genus, among which Debaryomyces, Fusarium, Pichia, Aspergillus, and Saccharomyces were the main dominant fungi. Debaryomyces and Trichosporon were conducive to the formation of taste qualities of Douchi, while Cladosporium and Candida have a negative impact on the taste quality of Douchi var correlation analysis. This study indicated the effects of dominant fungi on the formation of Douchi taste quality, allowing a deeper understanding of the role of microbial species in generating fermented soybean products in China. Our work provides theoretical support to guide the improvement of the industrial production process of Douchi.
