IntroductionResearch is needed to determine the impact of marketing on perceptions and use of reduced nicotine content (RNC) cigarettes, particularly as US regulators have permitted the sale of an RNC cigarette modified risk tobacco product (MRTP) that seeks further authorisation to advertise using modified risk claims. This study examined the effects of two advertising elements (product name and disclaimer content) on perceptions of an RNC cigarette MRTP.MethodsAdult participants (n=807, 28.7% smokers, 58.2% male, 74.2% non-Latinx white) completed an online MTurk survey. Participants were randomised to view one of six RNC cigarette advertisements, using a 2×3 between-subject factorial design to manipulate product name (‘Moonlight’ vs ‘Moonrise’) and disclaimer content (industry-proposed: ‘Nicotine is addictive. Less nicotine does NOT mean a safer cigarette’ vs focused: ‘Less nicotine does NOT mean a safer cigarette’ vs no content), then completed recall and product perception questionnaires.ResultsAll participants who viewed the industry-proposed disclaimer (vs no content) perceived greater addiction risk (p’s<0.05). Non-smokers who viewed this disclaimer also perceived greater health risks and held fewer false beliefs (p’s<0.05). Smokers who viewed Moonlight (vs Moonrise) ads perceived lower health risks (p<0.05).ConclusionsDisclaimer content may effectively inform consumers about addiction risk of a new RNC cigarette MRTP, and further inform non-smokers about health risks. This element, however, had little effect on perceived health risks among smokers, among whom the Moonlight product name was associated with health risk misperceptions similar to the banned ‘light’ descriptor.
Curvature tensors of higher-spin gauge theories derived from general Lagrangian densities
Authors: Baker Mark Robert , Bruce-Robertson Julia 
Published: April 2021

Curvature tensors of higher-spin gauge theories have been known for some time. In the past, they were postulated using a generalization of the symmetry properties of the Riemann tensor (curl on each index of a totally symmetric rank-n field for each spin-n). For this reason they are sometimes referred to as the generalized “Riemann” tensors. In this article, a method for deriving these curvature tensors from first principles is presented; the derivation is completed without any a priori knowledge of the existence of the Riemann tensors or the curvature tensors of higher-spin gauge theories. To perform this derivation, a recently developed procedure for deriving exactly gauge invariant Lagrangian densities from quadratic combinations of N order of derivatives and M rank of tensor potential is applied to the N = M = n case under the spin-n gauge transformations. This procedure uniquely yields the Lagrangian for classical electrodynamics in the N = M = 1 case and the Lagrangian for higher derivative gravity (“Riemann” and “Ricci” squared terms) in the N = M = 2 case. It is proven here by direct calculation for the N = M = 3 case that the unique solution to this procedure is the spin-3 curvature tensor and its contractions. The spin-4 curvature tensor is also uniquely derived for the N = M = 4 case. In other words, it is proven here that, for the most general linear combination of scalars built from N derivatives and M rank of tensor potential, up to N = M = 4, there exists a unique solution to the resulting system of linear equations as the contracted spin-n curvature tensors. Conjectures regarding the solutions to the higher spin-n N = M = n are discussed.

Published: April 2021

In this work, we report an amplified strong coupling phenomenon in a hybridized nanowire. The hybridized nanowire structure is composed of CH3NH3PbBr3 perovskite nanowire coated by SiO2 film and silver film. Due to the existence of silver film, Rabi splitting in hybrid structure can reach 303.2 meV, while the Rabi splitting in a pure perovskite nanowire is only 236.4 meV. Also, thicknesses of SiO2 film and Ag film can control the Rabi splitting of hybridized structure: (i) the thicker the Ag film, the greater the Rabi splitting; (ii) the thinner the SiO2 film, the greater the Rabi splitting. Finally, index of SiO2 film shows a linear relation with Rabi splitting.

The expansion of the Internet-of-Things (IoT) market is visible in homes, factories, public places, and smart cities. While the massive deployment of connected devices offers opportunities to improve quality of life and to develop new services, the impact of such devices on the security of the users in a context where the level of malicious threat continues to increase is a major concern. One of the challenges is the heterogeneity and constant evolution of wireless technologies and protocols used. To overcome this problem, we propose RIDS, a
Radio Intrusion Detection System
that is based on the monitoring and profiling of radio communications at the physical layer level using autoencoder neural networks. RIDS is independent of the wireless protocols and modulation technologies used. Besides, it is designed to provide a threefold diagnosis of the detected anomalies: temporal (start and end date of the detected anomaly), frequential (main frequency of the anomaly), and spatial (location of the origin of the anomaly). To demonstrate the relevance and the efficiency of our approach, we collected a large dataset of radio-communications recorded with three different probes deployed in an experimental room. Multiple real-world attacks involving a wide variety of communication technologies are also injected to assess the detection and diagnosis efficiency. The results demonstrate the efficiency of RIDS in detecting and diagnosing anomalies that occurred in the 400–500 Mhz and 800–900 Mhz frequency bands. It is noteworthy that compromised devices and attacks using these communication bands are generally not easily covered by traditional solutions.
Dual-Embedding based Deep Latent Factor Models for Recommendation
Authors: Cheng Weiyu , Shen Yanyan , Huang Linpeng , Zhu Yanmin 
Published: April 2021

Among various recommendation methods, latent factor models are usually considered to be state-of-the-art techniques, which aim to learn user and item embeddings for predicting user-item preferences. When applying latent factor models to the recommendation with implicit feedback, the quality of embeddings always suffers from inadequate positive feedback and noisy negative feedback. Inspired by the idea of NSVD that represents users based on their interacted items, this article proposes a dual-embedding based deep latent factor method for recommendation with implicit feedback. In addition to learning a primitive embedding for a user (resp. item), we represent each user (resp. item) with an additional embedding from the perspective of the interacted items (resp. users) and propose attentive neural methods to discriminate the importance of interacted users/items for dual-embedding learning. We design two dual-embedding based deep latent factor models, DELF and DESEQ, for pure collaborative filtering and temporal collaborative filtering (i.e., sequential recommendation), respectively. The novel attempt of the proposed models is to capture each user-item interaction with four deep representations that are subtly fused for preference prediction. We conducted extensive experiments on four real-world datasets. The results verify the effectiveness of user/item dual embeddings and the superior performance of our methods on item recommendation.

Published: April 2021

Background:
In 2007, the American Heart Association published updated evidence-based guidelines on the recommended use of antibiotic prophylaxis to prevent viridans group streptococcal (VGS) infective endocarditis (IE) in cardiac patients undergoing invasive procedures. The 2007 guidelines significantly scaled back the underlying conditions for which antibiotic prophylaxis was recommended, leaving only 4 categories thought to confer the highest risk of adverse outcome. The purpose of this update is to examine interval evidence of the acceptance and impact of the 2007 recommendations on VGS IE and, if needed, to make revisions based on this evidence.

Methods and Results:
A writing group was formed consisting of experts in prevention and treatment of infective endocarditis including members of the American Dental Association, the Infectious Diseases Society of America, and the American Academy of Pediatrics, in addition to the American Heart Association. MEDLINE database searches were done for English language articles on compliance with the recommendations in the 2007 guidelines and the frequency of and morbidity or mortality from VGS IE after publication of the 2007 guidelines. Overall, there was good general awareness of the 2007 guidelines but variable compliance with recommendations. There was no convincing evidence that VGS IE frequency, morbidity, or mortality has increased since 2007.

Conclusions:
On the basis of a review of the available evidence, there are no recommended changes to the 2007 VGS IE prevention guidelines. We continue to recommend VGS IE prophylaxis only for categories of patients at highest risk for adverse outcome while emphasizing the critical role of good oral health and regular access to dental care for all. Randomized controlled studies to determine whether antibiotic prophylaxis is effective against VGS IE are needed to further refine recommendations.

Rationale:
While respiratory failure is a frequent and clinically significant outcome of coronavirus disease 2019 (COVID-19), cardiac complications are a common feature in hospitalized COVID-19 patients and are associated with worse patient outcomes. The cause of cardiac injury in COVID-19 patients is not yet known. Case reports of COVID-19 autopsy heart samples have demonstrated abnormal inflammatory infiltration of macrophages in heart tissues.

Objective:
Generate an immunocardiac coculture platform to model macrophage-mediated hyperinflammation in COVID-19 hearts and screen for drugs that can block the macrophage-mediated inflammation.

Methods and Results:
We systematically compared autopsy samples from non–COVID-19 donors and COVID-19 patients using RNA sequencing and immunohistochemistry. We observed strikingly increased expression levels of CCL2 (C-C motif chemokine ligand 2) and macrophage infiltration in heart tissues of COVID-19 patients. We generated an immunocardiac coculture platform containing human pluripotent stem cell–derived cardiomyocytes and macrophages. We found that macrophages induce increased reactive oxygen species and apoptosis in cardiomyocytes by secreting IL (interleukin)-6 and TNF-α (tumor necrosis factor alpha) after Severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) exposure. Using this immunocardiac coculture platform, we performed a high content screen and identified ranolazine and tofacitinib as compounds that protect cardiomyocytes from macrophage-induced cardiotoxicity.

Conclusions:
We established an immuno-host coculture system to study macrophage-induced host cell damage following SARS-CoV-2 infection and identified Food and Drug Administration–approved drug candidates that alleviate the macrophage-mediated hyperinflammation and cellular injury.
Shape-Constrained Symbolic Regression—Improving Extrapolation with Prior Knowledge

Published: April 2021

AbstractWe investigate the addition of constraints on the function image and its derivatives for the incorporation of prior knowledge in symbolic regression. The approach is called shape-constrained symbolic regression and allows us to enforce, for example, monotonicity of the function over selected inputs. The aim is to find models which conform to expected behavior and which have improved extrapolation capabilities. We demonstrate the feasibility of the idea and propose and compare two evolutionary algorithms for shape-constrained symbolic regression: (i) an extension of tree-based genetic programming which discards infeasible solutions in the selection step, and (ii) a two-population evolutionary algorithm that separates the feasible from the infeasible solutions. In both algorithms we use interval arithmetic to approximate bounds for models and their partial derivatives. The algorithms are tested on a set of 19 synthetic and four real-world regression problems. Both algorithms are able to identify models which conform to shape constraints which is not the case for the unmodified symbolic regression algorithms. However, the predictive accuracy of models with constraints is worse on the training set and the test set. Shape-constrained polynomial regression produces the best results for the test set but also significantly larger models.
Art as Refuge: The Symbolic Transformation of an Electronic Installation in the Midst of Chile's Social Unrest
Authors: Núñez-Pacheco Claudia , Olivares-Retamal Jorge 
Published: April 2021

Abstract
This position statement describes the transformation of an interactive installation from an instrumental piece of art and science pedagogy into a meaningful performative piece, which forced its creators to adopt a political stance in the light of a period of social unrest taking place in Chile beginning in October 2019. It describes how an apparently nonpartisan installation transitioned into a tool for political expression and refuge. It also allowed the artists to rethink their role in the community as facilitators of art spaces for self-dialogue.
The Multi-Tuned Piano: Keyboard Music without a Tuning System
Authors: Dean Roger T. 
Published: April 2021

Abstract
Unlike a physical grand piano, a physical synthesis instrument, such as one of Pianoteq’s series of grand pianos, is not necessarily constrained at any moment to a single tuning system. This article discusses why a system using discrete piano pitches (not sliding pitches) chosen freely among the audible pitch continuum presents interesting musical and expressive possibilities. Audio and video of compositions and an improvisation exploiting the system demonstrate its potential and a performing interface for it.
The slowdown tends to be greater for stronger tropical cyclones
Authors: Sun Yuan , Zhong Zhong , Li Tim , Yi Lan , Shen Yixuan 
Published: April 2021

AbstractUnderstanding the impact of climate change on tropical cyclones (TCs) has become a hot topic. The slowdown of TC translation speed contributes greatly to the locally accumulated TC damage. While the recent observational evidence shows that TC translation speed has decreased globally by 10% since the mid-twentieth century, the robustness of the trend is questioned by other studies as effects of changes in observational capability can strongly affect the global trend. Moreover, none of the published studies considered dependence of TC slowdown on TC intensity. This is the caveat of these analyses as the effect of TC slowdown is closely related to TC intensity. Here, we investigate the relationship between TC translation speed trend and TC intensity, and reveal possible reasons for the trend. We show that the global slowing trend without weak TC moments (≤ 17 m s-1) is about double of that with weak TC moments in a recent study. This is because the slowing trend is dominated by strong TCs’ trend. Stronger (weaker) TCs tend to be controlled more by upper-level (lower-level) steering flow, and the calculated trend of upper-level steering flow is much larger than that of lower-level steering flow. This may be an important reason for the large difference between the slowing trend without weak TC moments and that with weak TC moments. Furthermore, the changes of TC tracks (including inter-basin trend and latitudinal shift), which are partly attributed to data inhomogeneity, make a much larger contribution to the slowing trend, compared with the weakening of tropical circulation, which is related to anthropogenic warming.
The Houses That Evo Built: Autonomy, Vivir bien, and Viviendas in Bolivia
Authors: Alderman Jonathan 
Published: April 2021

The concept of vivir bien (living well) has become ubiquitous in Bolivian state discourse and policy since the election of Evo Morales as Bolivia’s president in 2005. While Bolivia’s constitutional refounding as plurinational is supposed to facilitate indigenous peoples’ living according to their conception of living well, the state still appears to be attempting to implement its own conception through rural social programs promoted as enabling rural indigenous peoples to live well. The implementation of one such social program, a housing donation program in the municipality of Charazani (Department of La Paz), demonstrates differing notions of vivir bien between neighboring communities and suggests that a program designed to facilitate vivir bien may actually provide obstacles to the realization of an indigenous conception of living well. El concepto de vivir bien se ha vuelto omnipresente en el discurso y la política del estado boliviano desde la elección de Evo Morales como presidente en 2005. Si bien se supone que la refundación constitucional de Bolivia como estado plurinacional debe facilitar la vida de los pueblos indígenas de acuerdo a su concepción de vivir bien, el Estado aún parece estar tratando de implementar su propia concepción a través de programas sociales rurales promovidos como proyectos que permiten que los pueblos indígenas rurales vivan bien. La implementación de uno de estos programas sociales, un programa de donación de vivienda en el municipio de Charazani (Departamento de La Paz), muestra diferentes nociones de lo que implica vivir bien entre las comunidades vecinas y sugiere que un programa diseñado para facilitarlo puede, de hecho, generar obstáculos a la realización de una concepción indígena de vivir bien.
A qualitative study exploring the implementation determinants of rehabilitation and global wellness programs for orchestral musicians
Authors: Roos Marianne , Roy Jean-Sébastien , Lamontagne Marie-Eve 
Published: April 2021

Objective: To explore the facilitators and barriers to implementation of a pilot workplace rehabilitation and global wellness program for orchestral musicians. Design: Qualitative study comprising focus groups and interviews. Setting: Workplace of conservatory and orchestral musicians and administrators. Participants: Musicians, administrators and a conductor from two professional orchestras; tertiary-level orchestral students and an administrator from a conservatory of music. Interventions: We held four focus groups and two interviews to document the perspectives of the participants concerning the implementation determinants of a pilot workplace rehabilitation and wellness program (exercises and health-related education). Meetings consisted of questions based on the Consolidated Framework for Implementation Research. Thematic content analysis was conducted using this same framework, with subcoding according to the Theoretical Domains Framework. Results: Fourteen musicians and five administrators participated. Results suggest that the implementation determinants for the pilot and future programs rely mainly on the Inner Setting, that is, what musicians refer to as ‘the music world’, specifically cultural elements such as pain beliefs (e.g. no pain no gain) and lack of resources and time (barriers). Characteristics of Individuals such as social influences amongst colleagues and beliefs about the consequences of self-care or lack thereof, and Intervention Characteristics such as complexity can be facilitators or barriers. All emerging themes have an undercurrent that lies in the Inner Setting. Conclusion: Musicians’ culture, currently a barrier, is a crucial determinant of rehabilitation and wellness program implementation in the orchestral musicians’ workplace. A focus on musicians’ workplace environment is necessary to optimise implementation and intervention impacts.
