Skin Electronics: Next‐Generation Device Platform for Virtual and Augmented Reality

Virtual reality (VR) and augmented reality (AR) are overcoming the physical limits of real‐life using advances in devices and software. In particular, the recent restrictions in transportation from the coronavirus disease 2019 (COVID‐19) pandemic are making people more interested in these virtual experiences. However, to minimize the differences between artificial and natural perception, more human‐interactive and human‐like devices are necessary. The skin is the largest organ of the human body and interacts with the environment as the site of interfacing and sensing. Recent progress in skin electronics has enabled the use of the skin as the mounting object of functional devices and the signal pathway bridging humans and computers, with opening its potential in future VR and AR applications. In this review, the current skin electronics are summarized as one of the most promising device solutions for future VR/AR devices, especially focusing on the recent materials and structures. After defining and explaining VR/AR systems and the components, the advantages of skin electronics for VR/AR applications are emphasized. Next, the detailed functionalities of skin electronic devices, including the input, output, energy devices, and integrated systems, are reviewed for future VR/AR applications.
Serendipity: Chance Encounters in the Marketplace Enhance Consumer Satisfaction

Despite evidence that consumers appreciate freedom of choice, they also enjoy recommendation systems, subscription services, and marketplace encounters that seemingly occur by chance. This article proposes that enjoyment can, in some contexts, be higher than that in contexts involving choice. This occurs as a result of feelings of serendipity that arise when a marketplace encounter is positive, unexpected, and attributed to some degree of chance. A series of studies shows that feelings of serendipity positively influence an array of consumer outcomes, including satisfaction and enjoyment, perceptions of meaningfulness of an experience, likelihood of recommending a company, and likelihood of purchasing additional products from the company. The findings show that strategies based on serendipity are even more effective when consumers perceive that randomness played a role in how an encounter occurred, and not effective when the encounter is negative, the encounter occurs deterministically (i.e., planned by marketers to target consumers), and consumers perceive that they have enough knowledge to make their own choices. Altogether, this research suggests that marketers can influence customer satisfaction by structuring marketplace encounters to appear more serendipitous, as opposed to expected or entirely chosen by the consumer.
Defining Maritime 4.0: Reconciling principles, elements and characteristics to support maritime vessel digitalisation

H2020 European Research Council, Grant/Award Number: EU H2020 727982 Abstract As complex systems, maritime vessels generate and require the utilization of large amounts of data for maximum efficiency. Designing, developing, and deploying these systems in a digital world requires rethinking how people interact and utilize technology throughout all areas of the industry. With growing interests in Industry 4.0, there are broad opportunities for the incorporation and development of new digital solutions that will support the improvement and optimization of next generation systems. However, while different technologies have been deployed with various levels of success the current challenge is not generating data but being able to harmoniously integrate different data streams into the decision‐making process. To support the development of next generation vessels, a comprehensive understanding of Maritime 4.0 is necessary. Current conceptions of 4.0 within the industry remain ambiguous and based on our research, have demonstrated a divergence in the levels of technological maturity and digital solutions in different industry sectors. This study leverages current state‐of‐the‐art literature and a series of interviews to formulate a descriptive definition of Maritime 4.0 that incorporates technologies that can be integrated to support decision‐making. Through a rigorous, empirically grounded, and contextually relevant approach, the contribution of this study is the establishment of an organized set of technologies and characteristics related to 4.0 and establishment of a practical definition.

Ácidos grasos, bioactivos y actividades antioxidante y antimicrobiana de Ankyropetalum spp. , una nueva fuente de ácido nervónico. Los extractos de Ankyropetalum se obtuvieron usando dos medios de extracción diferentes (Soxhlet y baño ultrasónico). A estos extractos se les determinó el contenido fenólico, flavonoides, DPPH, FRAP, y la actividad antimicrobiana. Además, se determinó la composición de ácidos grasos mediante GC-MS. Se encontraron valores altos de contenido fenólico y flavonoide total en A. reuteri y A. gypsophiloides, respectivamente. Los valores de DPPH y FRAP fueron altos en A. arsusianum y A. gypsophiloides, respectivamente. Se obtuvieron mejores resultados utilizando metanol como disolvente y Soxhlet como extractor. Los resultados mostraron que los extractos parecen ser razonablemente efectivos contra los organismos ensayados, incluidos los aislados clínicos. Los resultados más prometedores se obtuvieron con todos los extractos USB de especies contra la Cándida parapsilosis. Es notable que los niveles de ácido nervónico en A. arsusianum y A. reuteri alcanzaron el 40%. A diferencia de otras fuentes de ácido nervónico en el mundo, la ausencia de ácido erúcico en el aceite vegetal aumenta el valor de estas plantas.
Effects of chronic and acute stressors on transplanted black mangrove (Avicennia germinans) seedlings along an eroding Louisiana shoreline

Coastal wetland restoration can be used to offset past wetland losses and/or reduce future losses due to land‐use changes, rising sea levels, and accelerating climate change. However, there is a need for information regarding the restoration‐relevant performance of foundation species like mangrove and marsh plants, including their responses to acute and chronic stressors that can affect restoration outcomes. Mangrove encroachment and poleward range expansion into marsh, facilitated by warming winters, has provided restoration practitioners in the northern Gulf of Mexico with a new foundation plant species to consider using during restoration. To evaluate the performance of transplanted mangroves and characterize restoration‐relevant marsh–mangrove interactions, we planted nursery‐raised black mangrove (Avicennia germinans) seedlings within different marsh cover treatments along an eroding marsh‐dominated shoreline in Louisiana. Mangrove seedling survival increased with greater densities of marsh cover, indicating that marsh grass (Spartina alterniflora) may facilitate mangrove establishment. However, only 35% of transplanted mangrove seedlings established after 10 weeks, suggesting a low return on resources expended in raising seedlings for 1–3 years in greenhouse conditions. Moreover, a 2018 freeze event killed 100% of transplanted mangrove seedlings, while nearby naturally established mangroves suffered minor damage. Our results, along with those in the mangrove restoration literature, indicate that planting mangroves in the northern Gulf of Mexico may not be the most efficient use of limited resources. Rather, restoration efforts may benefit from focusing initially on the restoration of abiotic conditions (e.g. elevation and hydrologic regimes), followed by using marsh plants (rather than transplanted mangroves) to jump‐start ecosystem development.
A Highly Configurable High-Level Synthesis Functional Pattern Library

FPGA has recently played an increasingly important role in heterogeneous computing, but Register Transfer Level design flows are not only inefficient in design, but also require designers to be familiar with the circuit architecture. High-level synthesis (HLS) allows developers to design FPGA circuits more efficiently with a more familiar programming language, a higher level of abstraction, and automatic adaptation of timing constraints. When using HLS tools, such as Xilinx Vivado HLS, specific design patterns and techniques are required in order to create high-performance circuits. Moreover, designing efficient concurrency and data flow structures requires a deep understanding of the hardware, imposing more learning costs on programmers. In this paper, we propose a set of functional patterns libraries based on the MapReduce model, implemented by C++ templates, which can quickly implement high-performance parallel pipelined computing models on FPGA with specified simple parameters. The usage of this pattern library allows flexible adaptation of parallel and flow structures in algorithms, which greatly improves the coding efficiency. The contributions of this paper are as follows. (1) Four standard functional operators suitable for hardware parallel computing are defined. (2) Functional concurrent programming patterns are described based on C++ templates and Xilinx HLS. (3) The efficiency of this programming paradigm is verified with two algorithms with different complexity.
Microbial and clinical factors are related to recurrence of symptoms after childhood lower respiratory tract infection

Childhood lower respiratory tract infections (LRTI) are associated with dysbiosis of the nasopharyngeal microbiota, and persistent dysbiosis following the LRTI may in turn be related to recurrent or chronic respiratory problems. Therefore, we aimed to investigate microbial and clinical predictors of early recurrence of respiratory symptoms as well as recovery of the microbial community following hospital admission for LRTI in children. To this end, we collected clinical data and characterised the nasopharyngeal microbiota of 154 children (4 weeks–5 years old) hospitalised for a LRTI (bronchiolitis, pneumonia, wheezing illness or mixed infection) at admission and 4–8 weeks later. Data were compared to 307 age-, sex- and time-matched healthy controls. During follow-up, 66% of cases experienced recurrence of (mild) respiratory symptoms. In cases with recurrence of symptoms during follow-up, we found distinct nasopharyngeal microbiota at hospital admission, with higher levels of Haemophilus influenzae/haemolyticus, Prevotella oris and other gram-negatives and lower levels of Corynebacterium pseudodiphtheriticum/propinquum and Dolosigranulum pigrum compared with healthy controls. Furthermore, in cases with recurrence of respiratory symptoms, recovery of the microbiota was also diminished. Especially in cases with wheezing illness, we observed a high rate of recurrence of respiratory symptoms, as well as diminished microbiota recovery at follow-up. Together, our results suggest a link between the nasopharyngeal microbiota composition during LRTI and early recurrence of respiratory symptoms, as well as diminished microbiota recovery after 4–8 weeks. Future studies should investigate whether (speed of) ecological recovery following childhood LRTI is associated with long-term respiratory problems. Composition of nasopharyngeal microbiota during LRTI in children is related to recurring respiratory symptoms in the following months, and to incomplete microbiota recovery. Future research may pinpoint host and microbial predictors of clinical outcomes. https://bit.ly/3aInAwN
Effects of experimental land management on habitat use by Eurasian Stone‐curlews

Effective conservation is often informed by focal species studies to identify beneficial land management interventions. For nocturnal or cryptic species, quantifying habitat use across individually marked animals can allow unbiased assessment of intervention efficacy and identify other important habitats. Here, using a landscape‐scale experiment, we examine whether interventions intended to create nesting habitat for the largely nocturnal Eurasian Stone‐curlew Burhinus oedicnemus within semi‐natural grassland also provide foraging habitat. GPS loggers were fitted to five adult Stone‐curlews during the breeding season within an extensive area of semi‐natural grassland (3850 ha, hereafter ‘grassland’), surrounded by a mosaic of arable cropland (total study area 118 600 ha). The largely closed‐sward grassland was diversified by experimental ground‐disturbance plots (the intervention) prior to this study. We used the GPS fixes to identify 1881 foraging locations (510 during nesting and 1371 post‐breeding) across the grassland and surrounding landscape. Most foraging locations were close to the nest‐site during the nesting period (90% within 1 km) or day‐roost during post‐breeding (90% within 5 km), but birds travelled up to 4.1 km from these sites during nesting and 13 km post‐breeding. Stone‐curlews were two‐ (by night) or three‐times (by day) more likely to select disturbed‐grassland over unmodified grassland for foraging during nesting, and c. 15 times more likely to do so post‐breeding. Spring‐sown crops and pig fields or manure heaps were also selected over grassland for nocturnal foraging. Given that central place foraging occurs in this species, conservation efforts that promote breeding attempts through ground‐disturbance should ensure suitable foraging habitat is near the nest (<1 km). Creating multiple areas of disturbed‐ground close to the edge of large grassland blocks can provide a network of nesting and foraging habitats, while allowing access to foraging habitats on the surrounding arable farmland. Similar interventions may benefit other disturbance associated grassland waders.
Clinical outcome comparison of suprapectoral and subpectoral tenodesis of the long head of the biceps with concomitant rotator cuff repair: A systematic review

Background Simultaneous repairs of rotator cuff and biceps tenodesis can be managed by tenodesis of long head of biceps tendon to a subpectoral or suprapectoral area. This review investigated long head of biceps tendon tenodesis with concomitant rotator cuff repair and evaluated the clinical outcomes and incidences of complications based on tenodesis location. Methods Medline, Cochrane, and Embase databases were searched for published, randomized or nonrandomized controlled studies and prospective or retrospective case series with the phrases “suprapectoral,” “subpectoral,” “tenodesis,” and “long head of biceps tendon”. Those with a clinical evidence Level IV or higher were included. Non-English manuscripts, review articles, commentaries, letters, case reports, and sole long head of biceps tendon tenodesis articles were excluded. Results From 481 studies, 13 were chosen. In total, 1194 subpectoral and 2520 suprapectoral tenodesis cases were investigated. Postoperative Constant-Murley and American Shoulder and Elbow Surgeons mean scores showed similar good results. In terms of complication incidences, while transient nerve injuries were more commonly seen in patients with subpectoral tenodesis, persistent bicipital pain and Popeye deformity are mostly seen in patients with suprapectoral tenodesis. Discussion Biceps tenodesis to suprapectoral or subpectoral area with concomitant rotator cuff repair demonstrated similar outcomes. Popeye deformity and persistent bicipital pain were higher in suprapectoral area and transient neuropraxia was found to be higher in subpectoral area. Level of evidence: IV.
Robust adaptive input-output control for a class of modular robotic systems via inverse optimality theory

This paper introduces a model-based robust adaptive input-output control framework for a family of robotic systems that include under-actuation, nonholonomic, and constrained properties. The proposed control framework can provide fast and effective controller generation for modular robotic systems (MRS) with interchangeable subsystems. The controller was first derived based on the general properties of nonholonomic robotic dynamic models while considering under-actuation and constraints. Then the adaptive control technique is introduced to overcome the effects such as inertia and force uncertainties. Robust augmentation is implemented via inverse optimality theory, which is verified with respect to a meaningful cost function. A simulation study on an aerial manipulator system with model uncertainty and disturbance was provided to demonstrate the characteristics and effectiveness of the proposed controller.

Second, there is an increase and a difference between initial understanding and after learning. Third, it can increase the interest and motivation of students who have difficulty calculating multiplication
Cleaning Up Our Act: Systems Engineering to Promote Business Model Innovation for the Offshore Exploration and Production Supply Chain Operations

Oil and gas offshore exploration and production (E & P) will remain necessary to meet increasing global energy demands. However, appraising and exploring these resources has a major impact on sustainability and faces many challenges. Improving the supply chain operations that support E&P activities presents opportunities to contribute to the United Nations (UN) Sustainable Development Goals (SDGs), but relies on organizations being able to adopt new strategies and technology and, innovate their current business models. Business model innovation (BMI) has not been actively pursued in this industry, partially due to the traditional operation management and due to the complexity in changing established models or adopting full-fledged archetypes. Thus, the present study proposes a more flexible and granular approach to BMI by defining elements to be adopted rather than proposing business models archetypes. To define the elements, an application of systems engineering (SE) is adopted through a morphological analysis (MA). They are presented in morphological boxes in three dimensions—technology, organization, and the human element—inspired by sustainable business model (SBM) literature. The elements are proposed as “bricks” for BMI where they can be adopted and re-arranged as necessary, providing granularity and flexibility to facilitate BMI for organizations of varying sizes.
Technology-enhanced socialisation into disciplinary writing in L2: insights from the perceptions of MA TEFL students

Abstract In order to obtain qualifications to teach English as a foreign language (TEFL), teacher candidates often need to commit themselves to writing a master’s (MA) thesis. In efforts to shed light on how MA thesis supervisors can support supervisees in the writing process, drawing on the theoretical framework of language socialisation, this article presents part of an ongoing action research study, exploring how MA TEFL students perceived technology-enhanced socialisation, i.e., developments in their competence, beliefs and practices, into disciplinary writing in English. Six first-year Polish MA TEFL students enrolled in MA thesis-oriented courses reflected on the process of becoming more competent MA thesis writers by answering online survey open-ended questions. The study reveals that thesis writing in L2 can be an overwhelming process, during which the students struggle emotionally, but which they are determined to complete. The results suggest that MA supervisors can support the socialisation of MA TEFL students – novice disciplinary L2 writers – by mindfully providing the students with guidance on and access to relevant and quality materials, by allowing for regular writing opportunities, as well as making space for supervisor–students and student–student interaction and feedback. As digital tools mediate the relationship between individual students and their social–material learning environment, technology is an important element of this environment and course design needs to include blended learning experiences to enhance the process of socialisation into disciplinary writing in L2.
