Peridynamic bond‐associated correspondence model: Wave dispersion property
Authors: Chan WaiLam , Chen Hailong 
Published: May 2021

AbstractThe peridynamic bond‐associated material correspondence model is a reformulation of the conventional correspondence model, in which the concept of bond‐associated states were introduced to inherently remove the material instability. Numerical studies, in terms of deformation analysis, have shown the effectiveness of the bond‐associated model in removing the material instability. In this study, the bond‐associated model is further examined concerning its wave dispersion property. Detailed procedure to derive the wave dispersion relation in this model is outlined. Different combinations of the peridynamic material point horizon and the bond‐associated horizon are studied for all three geometric dimensions. Potential effects of weight function on the wave dispersion property are also investigated. It is found that the bond‐associated material correspondence model can effectively remove the material instability for practical applications. However, for all one‐dimensional cases studied, except the conventional model, the initial slopes of all the wave dispersion curves are slightly larger than that predicted by the classical continuum mechanics model. For two‐dimensional analysis, material instability still exists for the combination of the peridynamic material point horizon being twice of the mesh spacing and the bond‐associated horizon being three times of mesh spacing. But compared to the conventional model, the material instability for this case was slightly improved as the intersections of the wave dispersion curve with the wavenumber axis were reduced from two to one. For the three representative weight functions studied, it is found that the weight function does not significantly change the wave dispersion relation in the bond‐associated material correspondence model, except for the one‐dimensional cases.

A subdivision strategy for adjoining cell mapping on the global optimal control in multi‐input‐multi‐output systems
Authors: Cheng Yongdong , Jiang Jun 
Published: May 2021

AbstractIn this paper, a subdivision strategy for the adjoining cell mapping method to solve the global optimal control problems for multi‐input‐multi‐output systems is proposed. The subdivision strategy constructs the discrete optimal control table first by a rough discretization of the state space, which can identify uncontrollable regions. Then the optimal feedback control from the selected initial state is instituted. The rough cells where the feedback control trajectory crosses are subdivided into smaller cells and the finer discrete optimal control table is obtained after the second search. The further discretization of the target cell and control inputs can further enhance the terminate control precision. The calculation can also take the advantage of GPU parallel technology that will greatly enhance the computation efficiency. Two examples illustrate the feasibility and validity of the subdivision strategy to solve optimal control problems for multi‐input‐multi‐output systems. The proposed method offers an efficient alternative numerical way to obtain the approximate optimal control solution with global optimum for nonlinear multi‐input‐multi‐output systems.

Published: May 2021

AbstractPurposeDescribing patterns of use, including changes in dose and interruptions is challenging. Group‐based trajectory modelling (GBTM) can be used to identify individuals with similar dose patterns. We provide an intuitive graphical representation of dose patterns in groups identified using GBTM. We illustrate our approach using two drugs with different combinations of available dosages.MethodsWe drew data on patients with MS followed from 1977 to 2014 in Montréal using two sub‐cohorts of subjects. A sub‐cohort of patients taking interferon‐beta‐1a and another of patients taking amitriptyline were identified from the initial cohort. We use GBTM to identify groups of patients with homogeneous dose patterns for each of the two drugs. We compared the graphical representation obtained from the fitted values of GBTM with our proposed approach, which consisted of using step functions whose values corresponded to the mode. Differences in characteristics across groups were identified using chi‐squares and analysis of variance, both weighted by the posterior probability of group membership.ResultsSeven patterns of dose were identified for interferon‐beta‐1a and five for amitriptyline. The graphical representations of the patterns of dose from GBTM included values outside of the prescribed doses and did not capture changes in dose as clearly as the proposed representation using step functions.ConclusionOur proposed approach which is based on the mode at each visit in each pattern provides an intuitive and realistic representation of dose patterns in groups identified with GBTM.

Medical sensors need to have excellent skin compliance, mechanical properties, sensitivity, and biological safety. This review focuses on recent progress in adhesive hydrogel systems, their structures, adhesion mechanisms, construction strategies, and emerging applications in the biomedical field.
A Facile Strategy for Low Young's Modulus PDMS Microbeads Enhanced Flexible Capacitive Pressure Sensors
Authors: Sun Yupeng , Tai Huiling , Yuan Zhen , Duan Zaihua , Huang Qi , Jiang Yadong 
Published: May 2021

AbstractFlexible pressure sensors are widely demanded in human care systems. A simple and effective strategy for sensor fabrication can markedly promote its application. Herein, a facile strategy is employed to prepare a flexible capacitive pressure sensor with a polydimethylsiloxane microbeads‐modified dielectric layer. Owing to the microbeads structure, the proposed sensor achieves a sensitivity of 0.048 kPa−1 in the range of 0–10 kPa with a wide dynamic range (up to 100 kPa). The sensitivity is nine times higher than that of the planar structure. Moreover, the microbeads structured sensor obtains a low limit of detection (0.2 kPa), fast response time (120 ms), and good stability (variation lower than 3.30% after 1000 loading/unloading cycles at 20 kPa). The finite‐elemental analysis reveals that the microbeads structure is critical to enhance the performance of sensors. Finally, the pressure sensor is successfully applied to detect touch signal, joints movement, and breathing, exhibiting its promising prospects as smart wearable devices. Furthermore, the strategy may provide a new idea for the microstructural design of capacitive pressure sensors.
Prevention is better than cure: Integrating habitat suitability and invasion threat to assess global biological invasion risk by insect pests under climate change

Published: May 2021

AbstractBACKGROUNDInvasive alien species cause substantial impacts on ecosystem, economy, and public health. Therefore, identifying areas at risk of invasion and establishment is essential for the development and implementation of preventive measures. In this study, we integrated information on species habitat suitability, location of airports and ports, and invasion threat maps to assess global invasion risk under climate change using the cucurbit beetle, Diabrotica speciosa (Germar, 1824), as a model organism.RESULTSSuitable and optimal habitats for D. speciosa were estimated in several regions beyond its native range and comprised all continents. A decrease in the extent of suitable and optimal habitats for D. speciosa was predicted in different climate change scenarios, resulting in a reduction in invasion risk in most regions. However, regions such as western Europe and isolated areas in southern Asia and Oceania were predicted to face an increase in invasion risk under climate change. Invasion pathways via airports and ports were identified in all continents.CONCLUSIONOur findings can be used in the development of phytosanitary measures against D. speciosa in high‐risk areas. Furthermore, the approach used in this study provides a framework for estimating the global risk of invasion by insect pests and other terrestrial organisms in different climate change scenarios. This information can be used by policy makers to develop preventive measures against species with potential to invade and spread in regions beyond their native range. © 2021 Society of Chemical Industry.

AbstractExploring signal amplification strategies to enhance the sensitivity of lateral flow immunoassay (LFIA) is of great significance for point‐of‐care (POC) testing of low‐concentrated targets in the field of in vitro diagnostics. Here, a highly‐sensitive LFIA platform using compact and hierarchical magneto–fluorescent assemblies as both target‐enrichment substrates and optical sensing labels is demonstrated. The large‐pored dendritic templates are utilized for high‐density incorporation of both superparamagnetic iron oxide nanoparticles (IOs) and quantum dots (QDs) within the vertical channels. The hierarchical structure is built via affinity‐driven assembly of IOs and QDs from organic phase with silica surface and mercapto‐organosilica intermediate layer, respectively. The sequential assembly with central–radial channels enables 3D loading of dual components and separately controlling of discrete functionalities. After the alkyl‐organosilica encapsulation and silica sealing, the composite spheres exhibit high stabilities and compatibility with LFIA for procalcitonin (PCT) detection. With the assistance of liquid‐phase antigen‐capturing, magnetic enrichment, and fluorescence‐signal amplification, a limit of detection of 0.031 ng mL−1 for PCT is achieved with a linear range from 0.012 to 10 ng mL−1. The current LFIA is robust and validated for PCT detection in real serum, which holds great diagnostic significance for precise guidance of antibiotic therapy with POC manner.

Published: May 2021

AbstractGroundwater is the main source of water for drinking, industrial, and irrigation uses for most nations. Groundwater quality deterioration occurs due to urban, agricultural, mining, and industrial expansions. This research deals with the assessment of groundwater quality index, correlation, clustering analysis, and major ions chemistry around Jampali opencast coal mine of Raigarh district, Chhattisgarh, India, where groundwater is the main source of drinking water. A total of 28 groundwater samples were collected from the different stations in the month of April 2019 and 11 physicochemical parameters were examined. The results of the physicochemical analysis showed that cation abundance follows the order Na+ > K+ > Mg2+ > Ca2+ in the groundwater, while anion abundance follows the order Cl− > NO3− > SO42− > F−. A strong positive correlation is observed between TDS–EC, TDS–Mg2+, TDS–Na+, TDS–Cl−, TDS–SO42− (r = 0.999, 0.871, 0.872, 0.846, and 0.801) and EC–Mg2+, EC–Na+, EC–Cl−, EC–SO42− (r = 0.871, 0.873, 0.846, 0.802). The two clusters demonstrate a blended genesis connected to anthropogenic and geogenic measures. Based on calculated water quality index (WQI) values, groundwater falls under two classes: excellent and good water. WQI values of the study region depict that 85.72% of samples come under the excellent category and 14.28% in the good category.
Charge algebra in Al(A)dSn spacetimes
Authors: Fiorucci Adrien , Ruzziconi Romain 
Published: May 2021

Abstract
The gravitational charge algebra of generic asymptotically locally (A)dS spacetimes is derived in n dimensions. The analysis is performed in the Starobinsky/Fefferman-Graham gauge, without assuming any further boundary condition than the minimal falloffs for conformal compactification. In particular, the boundary structure is allowed to fluctuate and plays the role of source yielding some symplectic flux at the boundary. Using the holographic renormalization procedure, the divergences are removed from the symplectic structure, which leads to finite expressions. The charges associated with boundary diffeomorphisms are generically non-vanishing, non-integrable and not conserved, while those associated with boundary Weyl rescalings are non-vanishing only in odd dimensions due to the presence of Weyl anomalies in the dual theory. The charge algebra exhibits a field-dependent 2-cocycle in odd dimensions. When the general framework is restricted to three-dimensional asymptotically AdS spacetimes with Dirichlet boundary conditions, the 2-cocycle reduces to the Brown-Henneaux central extension. The analysis is also specified to leaky boundary conditions in asymptotically locally (A)dS spacetimes that lead to the Λ-BMS asymptotic symmetry group. In the flat limit, the latter contracts into the BMS group in n dimensions.
Gauge invariant perturbation theory via homotopy transfer
Authors: Chiaffrino Christoph , Hohm Olaf , Pinto Allison F. 
Published: May 2021

Abstract
We show that the perturbative expansion of general gauge theories can be expressed in terms of gauge invariant variables to all orders in perturbations. In this we generalize techniques developed in gauge invariant cosmological perturbation theory, using Bardeen variables, by interpreting the passing over to gauge invariant fields as a homotopy transfer of the strongly homotopy Lie algebras encoding the gauge theory. This is illustrated for Yang-Mills theory, gravity on flat and cosmological backgrounds and for the massless sector of closed string theory. The perturbation lemma yields an algorithmic procedure to determine the higher corrections of the gauge invariant variables and the action in terms of these.
Acupuncture is associated with a positive effect on odour discrimination in patients with postinfectious smell loss—a controlled prospective study
Authors: Drews Tanja , Hummel Thomas , Rochlitzer Bettina , Hauswald Bettina , Hähner Antje 
Published: May 2021

Abstract
Introduction
Smell disorders are common in the general population and occur e.g., after infections, trauma or idiopathically Treatment strategies for smell loss range from surgery, medication to olfactory training, depending on the pathology, but they are limited This study examined the effect of acupuncture on olfactory function.

Methods
Sixty patients with smell loss following infections of the upper respiratory tract were included in this investigation Half of the study group were randomly assigned to verum acupuncture and the other half to sham acupuncture Olfaction was measured by means of the “Sniffin’ Sticks” test battery (odour threshold, discrimination and identification).

Results
Compared to sham acupuncture, verum was associated with an improvement of smell function as measured by the TDI score (p = 0.039) The improvement was largely determined by improvement in odour discrimination, and was significantly better in patients with a shorter duration of the disorder.

Conclusion
The present results suggest that acupuncture is an effective supplementary treatment option for patients with olfactory loss.

Published: May 2021

Abstract
Purpose
In patients suffering from autosomal dominant polycystic liver and kidney disease (ADPLKD), combined organ transplantation often poses a technical challenge due to the large volume of both organs. To simplify the transplantation procedure by improving the exposure of anatomical structures, we introduce a novel surgical technique of orthotopic liver and kidney transplantation.

Methods
The modified simultaneous liver and kidney transplantation technique via a right-sided L-incision included three steps: (1) right-sided nephrectomy in the recipient followed by (2) orthotopic liver transplantation in cava replacement technique and (3) the orthotopic kidney transplantation with arterial reconstruction to the right common iliac artery.

Results
In total, seven patients with ADPLKD were transplanted by using the modified transplantation technique. The mean operation time was 342.43 min (±68.77). Postoperative patients were treated for 6.28 days (±2.50) in the intensive care unit and were discharged from the surgical ward approximately 28 days (±5.66) after the operation with normal graft function. Complications associated with the use of the modified technique, such as bleeding, anastomotic stenosis, biloma, or urinoma, did not occur.

Conclusion
Modified simultaneous liver and kidney transplantation is a safe alternative for patients with ADPLKD. By combining right-sided nephrectomy and orthotopic graft transplantation, the approach optimizes the exposure of anatomical structures and simplifies the transplantation procedure. Additionally, the modified transplantation technique does not require a particular organ explantation procedure and can be applied for all liver and kidney grafts.

AbstractExtrapyramidal symptoms (EP) are not uncommon in Alzheimer’s Disease (AD); when present, they negatively influence the course of the disorder. A large proportion of AD patients shows concomitant Lewy bodies’ pathology post mortem. Total α Synuclein (αSyn) concentrations are frequently increased in the cerebrospinal fluid (CSF) of AD patients, but are decreased in Parkinson’s Disease (PD) and Dementia with Lewy Bodies (DLB). αSyn CSF concentrations in AD patients with EP (EP+) have not been reported so far. αSyn and the four Neurochemical Dementia Diagnostics (NDD) CSF biomarkers, (Aβ1-42, Aβ42/40, Tau, and pTau181), interpreted according to the Erlangen Score algorithm, were measured in patients with positive NDD results and presence of extrapyramidal symptoms (NDD + / EP+; n = 26), in patients with positive NDD results and absence of extrapyramidal symptoms (NDD+ / EP−; n = 54), and in subjects with negative NDD results (NDD−; n = 34). Compared to the NDD− controls (379.8 ± 125.2 pg/mL), NDD+ patients showed, on average, highly significantly increased CSF αSyn (519 ± 141.3 pg/mL, p < 0.01), but without differences between NDD+ / EP+ and NDD+ / EP− subgroups (p = 0. 38). Moderate but highly significant association was observed between concentrations of αSyn and Tau (r = 0.47, p < 0.01) and pTau181 (r = 0.65, p < 0.01). Adjusted for diagnoses, age, and sex, subjects with more advanced neurodegeneration on neuroimaging showed significantly lower αSyn concentrations (p < 0.02). In the setting AD versus controls, the area under the receiver operating characteristic (ROC) curve was 0.804 [0.712; 0.896] with the sensitivity and the specificity of 0.863 and 0.618, respectively. αSyn in AD patients does not differentiate between subjects with- and without EP. Its increased average concentration reflects probably neurodegenerative process, and is not specific for any pathophysiologic mechanisms. Further studies are necessary to explain the role of CSF αSyn as a potential biomarker.

Abstract
Aim
This study aimed to assess the impact of the Supporting Wellness at Pantries (SWAP) system on client food selections at a food pantry.

Subject and methods
In a pre–post comparison study design, a client-choice food pantry implemented SWAP by reorganizing its inventory to promote healthy options. Each product was ranked as “choose often” (green), “sometimes” (yellow), or “rarely” (red) based on saturated fat, sodium, and sugar. Signage was added to indicate each item’s SWAP rank and healthier foods were placed at eye level. Client food baskets were assessed at time 1 (n = 121) and time 2 (n = 101). The proportions of green and red foods selected were compared using regression analyses.

Results
The regression analyses showed that the proportion of green foods selected by clients increased by 11% (p < 0.001) and the proportion of red foods selected decreased by 7% (p < 0.001) after SWAP was implemented (n = 222).

Conclusions
SWAP has the potential to positively shift client choices among the items available in a food pantry setting. SWAP is one component of a suite of changes to the charitable food system that have the potential to alleviate food insecurity, improve diet quality, and assist clients in managing diet-related diseases.
