Published: September 2021

AbstractExhibiting high specific energy and low cost, lithium–sulfur batteries are considered promising candidates for the next‐generation battery. However, its wide applications are limited by the insulating nature of the sulfur, dissolution of polysulfide species, and large volume change of the sulfur cathode. In this work, a conductive binder, crosslinked polyfluorene (C‐PF) is synthesized and employed in Li–S batteries to enhance the overall electrochemical performance from the following three aspects: 1) possessing high electronic conductivity, C‐PF facilitates lowered areal resistance for the sulfur electrode and leads to an improved rate capability; 2) owing to the cross‐linked polymer structure, favorable mechanical properties of the electrode can be achieved, hence the well‐preserved electrode integrity; 3) forming strong binding with various polysulfide species, C‐PF manages to trap them from diffusing to the Li anode, which greatly improves the cycling stability of Li–S cells. Through designing a multifunctional binder to comprehensively enhance the Li–S cathode, this proposed approach could be broadly applied to fully harness the energy from S redox in addition to cathode material modifications.
Influence of new‐to‐old concrete interface on the damping behavior of recycled aggregate concrete
Authors: Li Tan , Xiao Jianzhuang , Singh Amardeep 
Published: September 2021

AbstractThe interface transition zone (ITZ) is a critical component of concrete, as it has a significant effect on the material's mechanical properties. This paper using specimens of bonded new and old concrete analyzes the effect of the interface in recycled concrete on damping performance using semi precast concrete specimens with old and new concrete. To determine the effect of the bonding zone between new and old concrete on the damping ratio of recycled concrete, the free vibration attenuation test method was used. When the acceleration signal from the specimen's transverse vibration is transformed to the frequency domain, the study observes two prominent peaks. The damping ratio is between 0.005 and 0.007 at the high‐frequency position and 0.06–0.08 at the low‐frequency position. When the excitation position is not in the bonding zone, the damping ratio measured in the bonding zone has a smaller average value. Under different recycled aggregate replacement rates, there is a significant difference in the damping ratio and frequency of old and new concrete bonded specimens, as well as complete recycled concrete specimens. The bonding zone's damping ratio data is more discrete than that of other locations. The damping ratio and the acceleration amplitude exhibit an excellent linear relationship, with the damping ratio increasing as the amplitude increases. The damping ratio varies significantly more in the longitudinal direction, with no apparent relationship to the acceleration amplitude.
Glycan Assembly Strategy: From Concept to Application
Authors: Liu Mingli , Qin Xianjin , Ye Xin‐Shan 
Published: September 2021

AbstractGlycans have been hot topics in recent years due to their exhibition of numerous biological activities. However, the heterogeneity of their natural source and the complexity of their chemical synthesis impede the progress in their biological research. Thus, the development of glycan assembly strategies to acquire plenty of structurally well‐defined glycans is an important issue in carbohydrate chemistry. In this review, the latest advances in glycan assembly strategies from concepts to their applications in carbohydrate synthesis, including chemical and enzymatic/chemo‐enzymatic approaches, as well as solution‐phase and solid‐phase/tag‐assisted synthesis, are summarized. Furthermore, the automated glycan assembly techniques are also outlined.
Closed string deformations in open string field theory. Part III. $$ \mathcal{N} $$ = 2 worldsheet localization
Authors: Maccaferri Carlo , Vošmera Jakub 
Published: September 2021

Abstract
In this paper, which is the last of a series including [1, 2] we first verify that the two open-closed effective potentials derived in the previous paper from the WZW theory in the large Hilbert space and the A∞ theory in the small Hilbert space have the same vacuum structure. In particular, we show that mass-term deformations given by the effective (open)2-closed couplings are the same, provided the effective tadpole is vanishing to first order in the closed string deformation. We show that this condition is always realized when the worldsheet BCFT enjoys a global $$ \mathcal{N} $$
N
= 2 superconformal symmetry and the deforming closed string belongs to the chiral ring in both the holomorphic and anti-holomorphic sector. In this case it is possible to explicitly evaluate the mass deformation by localizing the SFT Feynman diagrams to the boundary of world-sheet moduli space, reducing the amplitude to a simple open string two-point function. As a non-trivial check of our construction we couple a constant Kalb-Ramond closed string state to the OSFT on the D3–D(−1) system and we show that half of the bosonic blowing-up moduli become tachyonic, making the system condense to a bound state whose binding energy we compute exactly to second order in the closed string deformation, finding agreement with the literature.
Beyond Schrödinger-Poisson: nonrelativistic effective field theory for scalar dark matter
Authors: Salehian Borna , Zhang Hong-Yi , Amin Mustafa A. , Kaiser David I. , Namjoo Mohammad Hossein 
Published: September 2021

Abstract
Massive scalar fields provide excellent dark matter candidates, whose dynamics are often explored analytically and numerically using nonrelativistic Schrödinger-Poisson (SP) equations in a cosmological context. In this paper, starting from the nonlinear and fully relativistic Klein-Gordon-Einstein (KGE) equations in an expanding universe, we provide a systematic framework for deriving the SP equations, as well as relativistic corrections to them, by integrating out ‘fast modes’ and including nonlinear metric and matter contributions. We provide explicit equations for the leading-order relativistic corrections, which provide insight into deviations from the SP equations as the system approaches the relativistic regime. Upon including the leading-order corrections, our equations are applicable beyond the domain of validity of the SP system, and are simpler to use than the full KGE case in some contexts. As a concrete application, we calculate the mass-radius relationship of solitons in scalar dark matter and accurately capture the deviations of this relationship from the SP system towards the KGE one.
Benchmarking and optimization of robot motion planning with motion planning pipeline
Authors: Liu Shuai , Liu Pengcheng 
Published: September 2021

AbstractAlgorithms have been designed for robot motion planning with various adaptability to different problems. However, how to choose the most suitable planner in a scene has always been a problem worthy of research. This paper aims to find the most suitable motion planner for each query under three different scenes and six different queries. The work lies in optimization of sampling-based motion planning algorithms through motion planning pipeline and planning request adapter. The idea is to use the pre-processing of the planning request adapter, to run OMPL as a pre-processer for the optimized CHOMP or STOMP algorithm, and connect through the motion planning pipeline, to realize the optimization of the motion trajectory. The optimized trajectories are compared with original trajectories through benchmarking. The benchmarking determines the most suitable motion planning algorithm for different scenarios and different queries. Experimental results show that after optimization, the planning time of the algorithm is longer, but the efficiency is significantly improved. In the low-complexity scenes, STOMP optimizes the sampling algorithm very well, improves the trajectory quality greatly, and has a higher success rate. CHOMP also has a good optimization of the sampling algorithm, but it reduces the success rate of the original algorithm. However, in more complex scenes, optimization performance of the two optimization methods may not be as good as the original algorithm. In future work, we need to find better algorithms and better optimization algorithms to tackle with complex scenes.

Authors: Murata Tsuyoshi 
Published: September 2021

AbstractOngoing COVID-19 pandemic poses many challenges to the research of artificial intelligence. Epidemics are important in network science for modeling disease spread over networks of contacts between individuals. To prevent disease spread, it is desirable to introduce prioritized isolation of the individuals contacting many and unspecified others, or connecting different groups. Finding such influential individuals in social networks, and simulating the speed and extent of the disease spread are what we need for combating COVID-19. This article focuses on the following topics, and discusses some of the traditional and emerging research attempts: (1) topics related to epidemics in network science, such as epidemic modeling, influence maximization and temporal networks, (2) recent research of network science for COVID-19 and (3) datasets and resources for COVID-19 research.
Assessment of prospective memory after stroke utilizing virtual reality

Published: September 2021

AbstractProspective Memory (PM) is the ability to remember to do something in the future. It is often impaired after stroke and can impact on an individual’s level of independence and daily functioning. PM tasks have been criticized for their lack of ecological validity wherein test results may not be related to actual performance in daily life. With ecological validity in mind, the Virtual Reality Prospective Memory Shopping Task (VRPMST) was designed to assess two types of PM, time- and event-based. This study aimed to examine the ecological and convergent validity of the VRPMST in comparison to an experimental (Lexical Decision PM Task) and clinical measure of PM (Cambridge PM Test). Twelve individuals with stroke and 12 controls were administered three PM measures, three neuropsychological measures, and two user-friendliness questionnaires, one for the experimental PM measure and one for the VRPMST. Individuals with stroke showed impairments in PM compared to controls on all three PM measures, particularly time-based PM. Individuals with stroke were found to monitor time significantly less than controls on both the experimental PM measure and the VRPMST. The VRPMST was found to be sensitive in measuring PM, have better ecological validity when compared to the experimental PM measure, and good convergent validity. The findings of this study have helped to clarify that PM impairment does exist after stroke, possibly due to a problem in strategic monitoring. In addition, we have demonstrated how VR technology can be used to design a measure of cognitive function commonly impaired after stroke.
Prevalence of linezolid-resistant organisms among patients admitted to a tertiary hospital for critical care or dialysis

Published: September 2021

Abstract
Background
Linezolid is an oxazolidinone antimicrobial regarded as a “last resort” antimicrobial, used typically for treatment of Gram-positive bacterial infections. It is acknowledged that prevalence of resistance to linezolid is increasing in Europe. In Ireland, a number of outbreaks of linezolid-resistant isolates have been reported, including an outbreak at the location for this study, the Intensive Care Unit (ICU) of University Hospital Limerick (UHL).

Methods
The Chromagar™ Lin-R selective medium was validated using a panel of linezolid-sensitive and linezolid-resistant strains. Subsequently, the prevalence exercise focused on a convenience sample of patients (n = 159) in critical care wards, ICU (n = 23) and High-Dependency Unit (HDU, n = 51), in addition to patients undergoing dialysis therapy (n = 77). Eight additional patients had specimens collected when attending more than one location. Growth on Chromagar™ Lin-R agar was followed by drug sensitivity testing by disc diffusion and minimum inhibitory concentration (MIC) testing.

Results
A validation exercise was performed on 23 isolates: seven target and sixteen non-target organisms. Isolates performed as intended (100% sensitivity, 100% specificity). For the prevalence study, of 398 tests, 40 resulted in growth of non-target organisms (specificity approx. 90%). A sole patient (1/159) was identified as colonized by a linezolid-resistant Staphylococcus epidermidis, a prevalence of 0.63%. Molecular investigation confirmed presence of the G2576T mutation in the 23S rRNA.

Conclusion
While this point prevalence study identified extremely low carriage of linezolid-resistant bacteria, it remains prudent to maintain vigilance as reports of outbreaks associated with linezolid-resistant S. epidermidis (LRSE) in European critical care units are increasing.
Current strategies of mechanical stimulation for maturation of cardiac microtissues

Published: September 2021

AbstractThe most advanced in vitro cardiac models are today based on the use of induced pluripotent stem cells (iPSCs); however, the maturation of cardiomyocytes (CMs) has not yet been fully achieved. Therefore, there is a rising need to move towards models capable of promoting an adult-like cardiomyocytes phenotype. Many strategies have been applied such as co-culture of cardiomyocytes, with fibroblasts and endothelial cells, or conditioning them through biochemical factors and physical stimulations. Here, we focus on mechanical stimulation as it aims to mimic the different mechanical forces that heart receives during its development and the post-natal period. We describe the current strategies and the mechanical properties necessary to promote a positive response in cardiac tissues from different cell sources, distinguishing between passive stimulation, which includes stiffness, topography and static stress and active stimulation, encompassing cyclic strain, compression or perfusion. We also highlight how mechanical stimulation is applied in disease modelling.
Lifestyle Adjustments in Long-COVID Management: Potential Benefits of Plant-Based Diets
Authors: Storz Maximilian Andreas 
Published: September 2021

AbstractPurpose of ReviewThe SARS-CoV-2-pandemic has caused mortality and morbidity at an unprecedented global scale. Many patients infected with SARS-CoV-2 continue to experience symptoms after the acute phase of infection and report fatigue, sleep difficulties, anxiety, and depression as well as arthralgia and muscle weakness. Summarized under the umbrella term “long-COVID,” these symptoms may last weeks to months and impose a substantial burden on affected individuals. Dietary approaches to tackle these complications have received comparably little attention. Although plant-based diets in particular were shown to exert benefits on underlying conditions linked to poor COVID-19 outcomes, their role with regard to COVID-19 sequelae is yet largely unknown. Thus, this review sought to investigate whether a plant-based diet could reduce the burden of long-COVID.Recent FindingsThe number of clinical trials investigating the role of plant-based nutrition in COVID-19 prevention and management is currently limited. Yet, there is evidence from pre-pandemic observational and clinical studies that a plant-based diet may be of general benefit with regard to several clinical conditions that can also be found in individuals with COVID-19. These include anxiety, depression, sleep disorders, and musculoskeletal pain. Adoption of a plant-based diet leads to a reduced intake in pro-inflammatory mediators and could be one accessible strategy to tackle long-COVID associated prolonged systemic inflammation.SummaryPlant-based diets may be of general benefit with regard to some of the most commonly found COVID-19 sequelae. Additional trials investigating which plant-based eating patterns confer the greatest benefit in the battle against long-COVID are urgently warranted.

Introduction Health professions educators risk misunderstandings where terms and concepts are not clearly defined, hampering the field’s progress. This risk is especially pronounced with ambiguity in describing roles. This study explores the variety of terms used by researchers and educators to describe “faculty”, with the aim to facilitate definitional clarity, and create a shared terminology and approach to describing this term.
Methods The authors analyzed journal article abstracts to identify the specific words and phrases used to describe individuals or groups of people referred to as faculty. To identify abstracts, PubMed articles indexed with the Medical Subject Heading “faculty” published between 2007 and 2017 were retrieved. Authors iteratively extracted data and used content analysis to identify patterns and themes.
Results A total of 5,436 citations were retrieved, of which 3,354 were deemed eligible. Based on a sample of 594 abstracts (17.7%), we found 279 unique terms. The most commonly used terms accounted for approximately one-third of the sample and included faculty or faculty member/s (n = 252; 26.4%); teacher/s (n = 59; 6.2%) and medical educator/s (n = 26; 2.7%) were also well represented. Content analysis highlighted that the different descriptors authors used referred to four role types: healthcare (e.g., doctor, physician), education (e.g., educator, teacher), academia (e.g., professor), and/or relationship to the learner (e.g., mentor).
Discussion Faculty are described using a wide variety of terms, which can be linked to four role descriptions.

Published: September 2021

ABSTRACTThis introduction to the special collection begins with a historiographical overview of the American Renaissance. Here we will see how both popular perception and academic study of the subject have been affected by wider forces, including the advent of modernism, the emergence of the preservation movement and the increased attention given to social inequalities in public discourse today. This is the context in which the articles in the collection are situated and introduced. The final section considers aspects of the subject requiring further work, in particular the American Renaissance as a transnational phenomenon linked to the notion of the ‘Angloworld’.

AbstractThe prevalence of malnutrition is high among oncology patients in Northern China. Malnutrition is related to the longer hospital stay, and it can be used to predict the prognostic outcome of patients. This work focused on investigating the relationship of nutritional condition with the length of hospital stay (LOS) in Northern Chinese patients with lung adenocarcinoma (LUAD). The Patient-Generated Subjective Global Assessment (PG-SGA), Nutritional Risk Screening 2002 (NRS 2002) score, recent weight loss and BMI were assessed in a probabilistic sample of 389 LUAD patients without epidermal growth factor receptor (EGFR) mutations. This study collected the demographic and clinical features of patients in a prospective manner. Then, we examined the association of nutritional status with LOS among the population developing LUAD. According to the PG-SGA, 63 (16·3 %), 174 (44·7 %) and 78 (20·1 %) patients were at risk for undernutrition, moderate undernutrition and severe undernutrition, respectively. Nutritional risk was found in 141 (36·2 %) patients based on the NRS 2002. The average LOS for tumour patients in Northern China was 12·5 d. At admission, a risk of undernutrition or undernutrition according to the PG-SGA (P < 0·001), NRS 2002 (P < 0·001) and latest weight loss (P < 0·001) predicted the longer LOS. LOS was related to nutritional status and hospitalisation expenses (P < 0·001). LUAD patients who stayed in the ICU had a poorer nutritional status and a longer LOS (P < 0·001). In Northern Chinese patients with LUAD, a risk for undernutrition evaluated by the PG-SGA, the NRS 2002 and recent weight loss, but not BMI, could predict a longer LOS.
COVID-19 and the Violation of the Right to Basic Education of Learners with Disabilities in South Africa: An Examination of Centre for Child Law v Minister of Basic Education
Authors: Kamga Serges Djoyou 
Published: September 2021

AbstractThis article explores the extent to which the right to basic education of learners with disabilities in South Africa was guaranteed during the COVID-19 pandemic. It uses the Centre for Child Law v Minister of Basic Education (Centre for Child Law) as the main canvas for discussion. It argues that, notwithstanding its normative compliance with the international regime of the right to an inclusive basic education, the government has failed learners with disabilities during COVID-19. An examination of Centre for Child Law reveals that, not only did the government's directions for the phased return to school exclude learners with disabilities, they also required the closure of special schools where compliance with social distancing rules was impossible. This violated the right to inclusive education and substantive equality of learners with disabilities and highlighted the need to advance these rights through reasonable accommodation initiatives.
