Splendid isolation: a practical guide to the use of rubber dam part 2
Authors: Mackenzie Louis , Waplington Mike , Bonsor Steve 
Published: September 2020

Rubber dam isolation is generally considered to be the optimal method of moisture control in dentistry and is taught at the vast majority of dental schools worldwide. Unfortunately, undergraduate training does not always translate into use in dental practice, with the majority of clinicians never using a rubber dam, even for endodontic procedures, where its use is regarded as the standard of care nationally and internationally. The COVID-19 pandemic has increased interest in the use of rubber dam as a highly effective infection control barrier. As professional and patient experience of rubber dam isolation is extremely limited, this paper, and the preceding one, are designed to support the practical training of clinical teams in the confident, skilful use of rubber dam. Part two provides a practical guide to rubber dam isolation techniques for endodontic and operative/restorative procedures. CPD/Clinical Relevance: Mastering rubber dam isolation will enhance patient care and be professionally rewarding for clinical teams.
The restoration of structurally compromised endodontically treated teeth: principles and indications of post and core restorations
Authors: Ahmed Reem , Dubal Raj 
Published: September 2020

The use of posts to retain indirect restorations in structurally compromised teeth is a technique that has been used for many years. There are many factors that need to be considered prior to the provision of post- and core-retained crowns to reduce the risk of failure. This includes case selection and an understanding of the cumulative prognostic endodontic, periodontal and prosthodontic factors. Many clinicians are hesitant to use post- and core-retained restorations, due to an uncertainty of whether the treatment modality would work, and with some seeing it as an out-dated clinical technique. The evolution and widespread use of dental implants has also provided an additional fixed tooth replacement option, which may result in a reduced drive to retain structurally compromised teeth. As a result, fewer post-retained restorations are being placed, with the majority of these being old restorations present in the older age demographic. It is important for this treatment modality to remain within a clinician's armamentarium, not only for application when clinically appropriate but, with an ageing population with a heavily restored dentition, clinicians must be able to repair and replace these restorations when necessary. CPD/Clinical Relevance: A sound understanding of the biological and technical considerations in the provision of post and core restorations will allow clinicians to offer this treatment modality to appropriate patients with greater predictability and reduced failure rates.
Producing three-dimensional printed models of the hepatobiliary system from computed tomography imaging data

Published: September 2020

Introduction Macroscopic anatomy has traditionally been taught using cadaveric material, lectures and a variety of additional resources including online modules and anatomical models. Traditional plastic models are effective educational tools yet they have significant drawbacks such as a lack of anatomical detail, a lack of texturisation and cost. Three-dimensional printed models stand to solve these problems and widen access to high-quality anatomical teaching. This paper outlines the use of three-dimensional multiplanar imaging (computed tomography) in the development of an accurate model of the hepatobiliary system. Materials and methods Computed tomography scans were used to construct a virtual three-dimensional model of the hepatobiliary system. This was printed locally as a full-size colour model. We give a complete account of the process and software used. Discussion This study is among the first of a series in which we will document the newly formed Oxford Library of Anatomy. This series will provide the methodology for the production of three-dimensional models from computed tomography and magnetic resonance imaging scans, and the library will provide a complete collection of the most complex anatomical areas. We hope that these models will form an important adjunct in teaching anatomy to medical students and surgical trainees.
ENSAIO SOBRE O VALOR SOLIDARIEDADE: PROPOSTA TEÓRICO-HERMENÊUTICA PARA SUPERAÇÃO DO PARADIGMA ECONÔMICO NEOLIBERAL
Authors: De Araújo Jailton Macena 
Published: September 2020

No contexto brasileiro atual, a crise econômica e social se coloca como ponto central das discussões políticas. Nesta perspectiva, os direitos sociais devem ser implementados sob a conformação do valor social do trabalho, de modo a promover a materialidade axiológica assegurada no texto constitucional, a qual tem como objetivo a construção de uma sociedade livre, justa e solidária. Desta forma, é a partir da teoria da solidariedade que é possível respaldar, nas concepções pós-positivistas do direito (assentadas na ideologia liberal), uma discricionariedade que reorienta as demandas e as decisões do poder público para o núcleo constitucional que é evidenciado pelos direitos sociais. Assim, se coloca como problema a ser enfrentado no presente trabalho: é possível, nos termos dos valores abrigados na onstituição Federal de 1988, que prevê o equilíbrio socioeconômico democrático, promover a superação do paradigma econômico neoliberal, em busca da efetivação da solidariedade e da justiça social? Reconhecese que as discussões para se responder à pergunta são bem amplas e contraditórias, mas não se pode descurar que, embora haja uma pluralidade de alternativas, o núcleo comum, definido também pelo texto constitucional, é a racionalidade solidária, que a subjaz, estabelecendo-se como proposta teórico-hermenêutica os valores sociais do trabalho, da solidariedade e da justiça social como mecanismo de efetivação de uma democracia social e solidária. Para tanto, parte-se da proposta teórico-metodológica hipotético-dedutiva, na qual se reconhece a força normativa da constituição e o seu protagonismo na promoção do bem-estar preconizado no seu texto. Reconhece-se ainda que, apesar das adversidades socioeconômicas impostas pela realidade de crise do capital, apenas a racionalidade solidária será capaz de promover o equilíbrio necessário à manutenção da relação capital x trabalho.

Published: September 2020

Goal: This article aims to diagnose the profile, strategies, and innovation practices adopted by the information technology companies of a Regional Innovation Systems (RIS).
Design/ Methodology/ Approach: This study was carried out with 19 small and medium companies from a RIS in the state of Paraná, where we collect data relating to the infrastructure and investments in R&D, types of innovation projects, impact on revenue, activities of innovation, innovation protection methods, and information sources used by companies.
Results: The results showed that: companies with higher investments in R&D, which generate innovative products and patents, have a higher financial return; the generation of patents is incipient among the companies surveyed; product process and organizational innovation are the main innovation activities carried out; there is some difficulty in establishing external partnerships for the development of innovation, especially with universities; customers, users, and the internet are the primary sources of information used by companies.
Limitation of the investigation: With respect to research limitations, we point out that our research sample is limited to 19 companies. Thus, for the results to be generalized, a larger sample is recommended.
Practical implications: The article showed that the launch of innovative products on the market has positive effects on the financial performance of companies due to increased sales.
Originality/ Value: This paper offers a contribution to contextual studies of innovation in RIS. In addition, it presents an innovation profile of the technology companies of an RIS. These results can be used to compare and evaluate the innovation evolution in technology companies with other sectors and other RIS, or provide an indicator for the development of innovation policies for a region.
Die Erweiterung der Ackermann-Formel auf nicht vollständig steuerbare Strecken
Authors: Nuß Uwe 
Published: September 2020

Zusammenfassung
Im Beitrag wird gezeigt, wie sich die Ackermann’sche Formel zur Polvorgabe bei zeitkontinuierlichen Ein- und Mehrgrößenzustandsregelungen in einfacher Weise auf nicht vollständig steuerbare Regelstrecken erweitern lässt. Das vorgestellte Verfahren basiert auf einer teilsystemorientierten Zustandstransformation in Verbindung mit der Einführung zusätzlicher fiktiver Stellgrößen, über die nichtsteuerbare Streckeneigenwerte formal beeinflusst werden könnten, aber durch Nullsetzen dieser Stellgrößen nicht beeinflusst werden. Dem Reglerentwurf vorausgehende Maßnahmen zur Elimination von nicht steuerbaren Anteilen aus dem Streckenmodell sind daher nicht erforderlich. Im Vergleich zum Fall einer vollständig steuerbaren Regelstrecke erfordert die Anwendung des vorgestellten Verfahrens kaum Mehraufwand, was am Beispiel eines Eingrößen- und eines Mehrgrößensystems illustriert wird.
3D camera-based markerless navigation system for robotic osteotomies

Published: September 2020

Abstract
A markerless system for the registration of a bone’s pose is presented which reduces the setup time and the damage to the bone to a minimum. For the registration, a particle filter is implemented which is able to estimate a bone’s pose using depth images. In a phantom study, the pose of 3D-printed bones has been estimated at a rate of 90 Hz and with a precision of a few millimeters. The particle filter is stable under partial occlusions and only diverges when the bone is fully occluded. During a cadaver study, the preoperatively planned cutting edges have been projected as augmented reality (AR) templates onto the hip bones of five cadavers. By cutting manually along the AR templates, surgeons were able to extract ten transplants in the same time as with conventional osteotomy templates. Using the presented navigation system can save hours spent on the construction and production of conventional templates. In conclusion, this work represents one step towards a broader acceptance of robotic osteotomies.
Parametric eigenvalue assignment by constant output feedback – a cascaded approach
Authors: Konigorski Ulrich

Abstract
In this paper a numerical efficient approach to the problem of eigenvalue assignment by constant output feedback is presented. It improves the well known Kimura’s condition by 2, i. e., it is shown that if

m

m+p\ge n-1

generically a solution to this design problem exists where

n
,
m

n,m

and p denote the dimensions of the system states, inputs and outputs, respectively. The algorithm is based on a cascaded control scheme with up to three design steps. The first two steps merely require standard methods from linear algebra while the last step only in case of

m

m+p=n-1

demands for the numerical solution of a system of three polynomial equations each of order two. The design procedure explicitly embodies all degrees of freedom beyond eigenvalue assignment. Thus, they can be used to account for other design it is shown goals, e. g., to minimize the spectral condition number of the closed-loop system or a norm of the feedback gain as it is shown by numerical examples from literature.
Rational synthesis of silicon into polyimide-derived hollow electrospun carbon nanofibers for enhanced lithium storage

Published: September 2020

Abstract
Flexible energy devices with high energy density and long cycle life are considered to be promising applications in portable electronics. In this study, silicon/carbon nanofiber (Si@CNF) core–shell electrode has been prepared by the coaxial electrospinning method. The precursors of polyimide (PI) were for the first time used to form the core–shell structure of Si@CNF, which depicts outstanding flexibility and mechanical strength. The effect of doping concentrations of silicon (Si) nanoparticles embedded in the fiber is investigated as a binder-free anode for lithium-ion batteries. A 15 wt% doped composite electrode demonstrates superior performance, with an initial reversible capacity of 621 mA h g−1 at the current density of 100 mA g−1 and a high capacity retention up to 200 cycles. The excellent cycling performance is mainly due to the carbonized PI core–shell structure, which not only can compensate for the insulation property of Si but also has the ability to buffer the volume expansion during the repeated charge–discharge process.
Persuasive Advertising in a Vertically Differentiated Competitive Marketplace
Authors: Lin Yuanfang , Narasimhan Chakravarthi 
Published: September 2020

AbstractDespite the widely acknowledged existence in practice, the theoretical literature on persuasive advertising is generally vague about exactly how such advertising could affect consumer preferences, except for the general assumption that persuasive advertising affects consumer willingness to pay or simply “shifts demand.” This paper proposes a theoretical framework for characterizing different ways that persuasive advertising may affect consumer utility in a vertically differentiated marketplace. Firstly, persuasive advertising could simply raise consumers’ reservation price for the product category. Secondly, persuasive advertising could enhance consumers’ perception about the product quality offered by the advertising firm. Thirdly, persuasive advertising could increase consumers’ willingness to pay for quality increment. Preliminary evidences from lab studies are presented to support the existences of the proposed effects. Using a game-theoretic approach, we study two firms’ decision in the adoption of persuasive advertising of a particular effect and the associated price competition. Findings from the theoretical model analyses indicate that factors influencing a firm’s decision in persuasive advertising include consumer heterogeneity, degree of product differentiation, the effectiveness and the cost of such advertising. In a vertically differentiated competitive marketplace, persuasive adverting is a more desirable strategic tool for firms of higher-quality products to further establish a competitive advantage.
Neural Cadherin Plays Distinct Roles for Neuronal Survival and Axon Growth under Different Regenerative Conditions

Published: September 2020

AbstractGrowing axons in the CNS often migrate along specific pathways to reach their targets. During embryonic development, this migration is guided by different types of cell adhesion molecules (CAMs) present on the surface of glial cells or other neurons, including the neural cadherin (NCAD). Axons in the adult CNS can be stimulated to regenerate, and travel long distances. Crucially, however, while a few axons are guided effectively through the injured nerve under certain conditions, most axons never migrate properly. The molecular underpinnings of the variable growth, and the glial CAMs that are responsible for CNS axon regeneration remain unclear. Here we used optic nerve crush to demonstrate that NCAD plays multifaceted functions in facilitating CNS axon regeneration. Astrocyte-specific deletion of NCAD dramatically decreases regeneration induced by phosphatase and tensin homolog (PTEN) ablation in retinal ganglion cells (RGCs). Consistent with NCAD’s tendency to act as homodimers, deletion of NCAD in RGCs also reduces regeneration. Deletion of NCAD in astrocytes neither alters RGCs’ mammalian target of rapamycin complex 1 (mTORC1) activity nor lesion size, two factors known to affect regeneration. Unexpectedly, however, we find that NCAD deletion in RGCs reduces PTEN-deletion-induced RGC survival. We further show that NCAD deletion, in either astrocytes or RGCs, has negligible effects on the regeneration induced by ciliary neurotrophic factor (CNTF), suggesting that other CAMs are critical under this regenerative condition. Consistent with this notion, CNTF induces expression various integrins known to mediate cell adhesion. Together, our study reveals multilayered functions of NCAD and a molecular basis of variability in guided axon growth.
Toward a Feeling of Animacy
Authors: Cohen Brianne 
Published: September 2020

This essay offers a comparative analysis of two moving-image artworks, UuDam Tran Nguyen's Serpents' Tails (2015) and Tuaấn Mami's In One's Breath—Nothing Stands Still (2018), in order to address questions of contemporary artmaking, ecological devastation, and the public sphere in Vietnam. Set in Ho Chi Minh City, Serpents' Tails hails a question of air pollution, depicting a thrilling dance between humans and “serpents' tails” created from plastic, throwaway bags, and the exhaust fumes of motorbikes. In contrast, the slower-paced In One's Breath—Nothing Stands Still critiques extractive limestone mining in rural northern Vietnam, a process that smothers the land in a kind of white, powdery haze and slow death grip. Both works highlight a question of inequitable breathability in relation to the airscape.
In comparing these two artworks, this essay aims to parse out intertwined ecological concerns in urban and rural Vietnam, represented by expressions of breathability, in relation to sociopolitical questions of speakability and animacy. Matters of more-than-human animacy cannot be divorced from pressing issues of coloniality, indigeneity, gender, sex, race, and climate justice. When “voice” and “agency” are structurally oppressed in linguistic form, eliminating a grammar of animacy (Robin Wall Kimmerer) that would convey the vitality of “nonliving” beings, then I argue that one may recuperate a feeling of animacy through the visual realm. With emotional charge, Serpents' Tails and In One's Breath—Nothing Stands Still engender a sense of nonhumans' mutual animacy, attempting to re-instill a feeling of respect for, and reciprocity with, the living land.

Abstract
Seed germination is characterized by a constant change of gene expression across different time points. These changes are related to specific processes, which eventually determine the onset of seed germination. To get a better understanding on the regulation of gene expression during seed germination, we performed a quantitative trait locus mapping of gene expression (eQTL) at four important seed germination stages (primary dormant, after-ripened, six-hour after imbibition, and radicle protrusion stage) using Arabidopsis thaliana Bay x Sha recombinant inbred lines (RILs). The mapping displayed the distinctness of the eQTL landscape for each stage. We found several eQTL hotspots across stages associated with the regulation of expression of a large number of genes. Interestingly, an eQTL hotspot on chromosome five collocates with hotspots for phenotypic and metabolic QTL in the same population. Finally, we constructed a gene co-expression network to prioritize the regulatory genes for two major eQTL hotspots. The network analysis prioritizes transcription factors DEWAX and ICE1 as the most likely regulatory genes for the hotspot. Together, we have revealed that the genetic regulation of gene expression is dynamic along the course of seed germination.
