AbstractBone has a remarkable potential for self-healing and repair, yet several injury types are non-healing even after surgical or non-surgical treatment. Regenerative therapies that induce bone repair or improve the rate of recovery are being intensely investigated. Here, we probed the potential of bone marrow stem cells (BMSCs) engineered with chemically modified mRNAs (modRNA) encoding the hBMP-2 and VEGF-A gene to therapeutically heal bone. Induction of osteogenesis from modRNA-treated BMSCs was confirmed by expression profiles of osteogenic related markers and the presence of mineralization deposits. To test for therapeutic efficacy, a collagen scaffold inoculated with modRNA-treated BMSCs was explored in an in vivo skull defect model. We show that hBMP-2 and VEGF-A modRNAs synergistically drive osteogenic and angiogenic programs resulting in superior healing properties. This study exploits chemically modified mRNAs, together with biomaterials, as a potential approach for the clinical treatment of bone injury and defects.
Quantum dissipative adaptation
Authors: Valente Daniel , Brito Frederico , Werlang Thiago 
Published: January 2021

AbstractDissipative adaptation is a general thermodynamic mechanism that explains self-organization in a broad class of driven classical many-body systems. It establishes how the most likely (adapted) states of a system subjected to a given drive tend to be those following trajectories of highest work absorption, followed by dissipated heat to the reservoir. Here, we extend the dissipative adaptation phenomenon to the quantum realm. We employ a fully-quantized exactly solvable model, where the source of work on a three-level system is a single-photon pulse added to a zero-temperature infinite environment, a scenario that cannot be treated by the classical framework. We find a set of equalities relating adaptation likelihood, absorbed work, heat dissipation and variation of the informational entropy of the environment. Our proof of principle provides the starting point towards a quantum thermodynamics of driven self-organization.
Large flux-mediated coupling in hybrid electromechanical system with a transmon qubit

Published: January 2021

AbstractControl over the quantum states of a massive oscillator is important for several technological applications and to test the fundamental limits of quantum mechanics. Addition of an internal degree of freedom to the oscillator could be a valuable resource for such control. Recently, hybrid electromechanical systems using superconducting qubits, based on electric-charge mediated coupling, have been quite successful. Here, we show a hybrid device, consisting of a superconducting transmon qubit and a mechanical resonator coupled using the magnetic-flux. The coupling stems from the quantum-interference of the superconducting phase across the tunnel junctions. We demonstrate a vacuum electromechanical coupling rate up to 4 kHz by making the transmon qubit resonant with the readout cavity. Consequently, thermal-motion of the mechanical resonator is detected by driving the hybridized-mode with mean-occupancy well below one photon. By tuning qubit away from the cavity, electromechanical coupling can be enhanced to 40 kHz. In this limit, a small coherent drive on the mechanical resonator results in the splitting of qubit spectrum, and we observe interference signature arising from the Landau-Zener-Stückelberg effect. With improvements in qubit coherence, this system offers a platform to realize rich interactions and could potentially provide full control over the quantum motional states.

Perceptions of Black Children's Narrative Language: A Mixed-Methods Study
Authors: Mills Monique T. , Moore Leslie C. , Chang Rong , Kim Somin , Frick Bethany 
Published: January 2021

Purpose
In this mixed-methods study, we address two aims. First, we examine the impact of language variation on the ratings of children's narrative language. Second, we identify participants' ideologies related to narrative language and language variation.

Method
Forty adults listened to and rated six Black second-grade children on the quality of 12 narratives (six fictional, six personal). Adults then completed a quantitative survey and participated in a qualitative interview.

Results
Findings indicated that adults rated students with less variation from mainstream American English (MAE) more highly than students with greater variation from MAE for fictional narratives, but not for personal narratives. Personal narratives tended to be evaluated more favorably by parents than teachers. Black raters tended to assign higher ratings of narrative quality than did White raters. Thematic analysis and conversation analysis of qualitative interviews supported quantitative findings and provided pertinent information about participants' beliefs.

Conclusion
Taken together, quantitative and qualitative results point to a shared language ideology among adult raters of variation from MAE being more acceptable in informal contexts, such as telling a story of personal experience, and less acceptable in more formal contexts, such as narrating a fictional story prompted by a picture sequence.

Authors: McIntyre Nancy S. , Tomaszewski Brianne , Hume Kara A. , Odom Samuel L. 
Published: January 2021

Purpose
For many individuals with autism spectrum disorder (ASD), postsecondary outcomes are poor. This may be due to insufficient academic supports, particularly with regard to literacy skills, during high school. More information is needed about skill profiles so that we can better differentiate support for students with varying social, communication, cognitive, and academic proficiency levels. This study was designed to (a) identify unique literacy profiles of high school students with ASD, (b) assess profile stability over time, (c) identify predictors of profile membership, and (d) analyze stakeholder reports of required school support intensity.

Method

Participants were a diverse sample of high school students with ASD, 14–21 years old (
N
= 544), their parents, and their teachers who participated in a randomized controlled trial of a comprehensive treatment model for high school students with ASD. Standardized measures were administered to assess nonverbal IQ, autism symptomatology, language/adaptive communication, reading comprehension, academic knowledge, and parent/teacher report of school support needs intensity. Latent transition analysis was conducted to examine sample heterogeneity and to explore the stability of the profiles. Associations between profiles and reports of support intensity were examined.

Results

Four literacy profiles were identified that were stable over 2 years: Emergent Literacy/Comprehensive Support, Low Literacy/Intensive Support, Average Literacy/Moderate Support, and Average Literacy/Limited Support
.
Parent and teacher reports of school support intensity generally aligned with the profiles.

Conclusions
These analyses provide insight into the diverse literacy and support needs in ASD. Implications for practice and the role of speech-language pathologists in assessment and intervention are discussed.

Revisiting the active power direction method
Authors: Shcherbakova Polina , Senderovych Gennady , Abramovitz Alexander 
Published: January 2021

AbstractThis paper presents a re‐examination of the active power direction method for locating the distortion sources in the power distribution network. The inaccuracies in the earlier analysis challenging the active power direction method are identified, and the claim of the inconsistency of the method is re‐examined. The article shows the derivation of the expression for the complex power, from which the equation for the active power flow through the point of measurement was derived in an explicit and in a normalised form. The derivations allow establishing the consumer dominance range at any harmonic frequency easily. Simulation results decisively support the theoretical findings. It is suggested that the main cause of uncertainty associated with the active power direction method is the stochastic nature of the amplitude and, especially, the phase between the harmonic current components.
Iterative multi‐scale residual network for deblurring
Authors: Zhang Tianlin , Li Jinjiang , Hua Zhen 
Published: January 2021

AbstractIn dynamic scene deblurring, recent neural network–based methods have been very successful. But with the improvement of deep deblurring performance, network structure and learning become more complicated. Compared with large‐scale network parameters and complex network structures, an iterative multi‐scale residual network to achieve a more effective parameter sharing scheme is proposed. In each iterative unit, fast multi‐scale residual blocks to replace superimposed convolutional layers or classic residual blocks are used. On the basis of preventing model overfitting, the receptive field of the network is increased. At the same time, the gated recurrent unit is introduced to connect modules of different stages. The model does not rely on the estimation of the blur kernel and directly generates sharp images in an end‐to‐end manner. The experimental structure on the benchmark dataset and real‐world images showed that this method has better quality than the existing methods in terms of large‐scale blur and subjective perception effects, both in quantitative and qualitative terms.

Context. Many galaxy clusters host megaparsec-scale diffuse radio sources called radio halos. Their origin is tightly connected to the processes that lead to the formation of clusters themselves. In order to reveal this connection, statistical studies of the radio properties of clusters combined with their thermal properties are necessary. For this purpose, we selected a sample of galaxy clusters with M500 ≥ 6 × 1014 M⊙ and z = 0.08 − 0.33 from the Planck Sunyaev–Zel’dovich catalogue. In Paper I, we presented the radio and X-ray data analysis that we carried out on the clusters of this sample.
Aims. In this paper we exploit the wealth of data presented in Paper I to study the radio properties of the sample, in connection to the mass and dynamical state of clusters.
Methods. We used the dynamical information derived from the X-ray data to assess the role of mergers in the origin of radio halos. We studied the distribution of clusters in the radio power–mass diagram, the scaling between the radio luminosity of radio halos and the mass of the host clusters, and the role of dynamics in the radio luminosity and emissivity of radio halos. We measured the occurrence of radio halos as a function of the cluster mass and we compared it with the expectations of models developed in the framework of turbulent acceleration.
Results. We find that more than the 90% of radio halos are in merging clusters and that their radio power correlates with the mass of the host clusters. The correlation shows a large dispersion. Interestingly, we show that cluster dynamics contributes significantly to this dispersion, with more disturbed clusters being more radio luminous. Clusters without radio halos are generally relaxed, and the upper limits to their diffuse emission lie below the correlation. Moreover, we show that the radio emissivity of clusters exhibits an apparent bimodality, with the emissivity of radio halos being at least ∼5 times larger than the non-emission associated with more relaxed clusters. We find that the fraction of radio halos drops from ∼70% in high-mass clusters to ∼35% in the lower mass systems in the sample and we show that this result is in good agreement with the expectations from turbulent re-acceleration models.
Elicitation of US and Chinese expert judgments show consistent views on solar geoengineering

Published: January 2021

AbstractExpert judgments on solar geoengineering (SG) inform policy decisions and influence public opinions. We performed face-to-face interviews using formal expert elicitation methods with 13 US and 13 Chinese climate experts randomly selected from IPCC authors or supplemented by snowball sampling. We compare their judgments on climate change, SG research, governance, and deployment. In contrast to existing literature that often stress factors that might differentiate China from western democracies on SG, we found few significant differences between quantitative judgments of US and Chinese experts. US and Chinese experts differed on topics, such as desired climate scenario and the preferred venue for international regulation of SG, providing some insight into divergent judgments that might shape future negotiations about SG policy. We also gathered closed-form survey results from 19 experts with >10 publications on SG. Both expert groups supported greatly increased research, recommending SG research funding of ~5% on average (10th–90th percentile range was 1–10%) of climate science budgets compared to actual budgets of <0.3% in 2018. Climate experts chose far less SG deployment in future climate policies than did SG experts.

Significance
Wireless electronics for monitoring of skin hydration in a quantitative fashion have broad relevance to our understanding of dermatological health and skin structure in both clinical and home settings. Here, we present a miniaturized, long-range automated system that adheres gently to the skin to yield quantitative recordings of skin water content for both epidermis and dermis. This system supports capabilities in characterizing skin barrier, assessing severity of skin diseases, and evaluating cosmetic and medication efficacy, with high levels of repeatability and insensitivity to ambient. Benchtop and pilot studies on patients with skin diseases highlight key features of these devices and their potential for broad utility in clinical research and in home settings to guide the management of disorders of the skin.

Authors: Zhang Lei , Chen Minpeng , Teng Fei , Ewing Jackson 
Published: January 2021

ABSTRACT
Since its launch in 2013, the Chinese Road and Belt Innitiative (BRI) has grown into a platform for any countries and regions that wish to participate, with global connectivity as the orienting goal. However, since its inception, concerns over the BRI’s potential impacts on ecology, environment and resilience, as well as its implications for global climate change and sustainability, have gathered force. As this thematic issue goes to press, these already complex BRI issues have been compounded by challenges from the COVID-19 pandemic. Whether and how the BRI can meet these challenges are questions worthy of deep exploration. This emerging BRI scholarship studied various aspects of BRI activities. However, major knowledge gaps remain regarding BRI impacts on GHG emission and on climate adaptation and sustainable resource management more broadly. To this end, this thematic issue aims to contribute to deeper understandings of climate and environmental changes along the BRI by bringing together state-of-art research and views on climate change patterns, trends, risks, impacts and adaptation.

Published: January 2021

Abstract
In the current work, a distinct class of Ca0.87Al2O4: 0.01Eu2+, 0.02Nd3+, 0.1Si4+ long afterglow phosphor powder was synthesized using high-temperature (1000–1500 °C) solid-state reaction method followed by formulation of an ink using epoxy based colloidal suspension. Interestingly the ink absorbs invisible energies either from D65 light and/or ultraviolet (∼365 nm) light, stores up the energy and emit as bright blue (∼450 nm) photoluminescence (PL) apparently visible for >4 h for dark adapted human eyes. Furthermore, the phenomenon of long (>4 h) afterglow allows us to create/design unique concealed patterns on goods and certificates using quick response (QR) code patterns. Systematic experiments have been carried out in a dark chamber on different models held a few seconds under UV (∼365 nm) excitation to distinguish fake merchandise products, barcodes and prevent counterfeit of currency as well as excessive UV radiation exposure for longer periods of time.

Published: January 2021

Abstract
In this study, experimental neutron capture cross section for the reaction 164Dy(n, γ )165Dy at 0.0334 eV was measured for the first time using monochromatic neutrons coming out of a high resolution neutron diffractometer at the BAEC TRIGA Research Reactor (BTRR), Dhaka, Bangladesh. The 197Au(n, γ )198Au monitor reaction was used to determine the effective neutron flux. The activities of the irradiated target and monitors were measured nondestructively using the HPGe detector coupled with the digital gamma-ray spectrometry system. The full energy photo peak detection efficiency curve of the detector was constructed using standard gamma-ray emitting sources and this curve was used to acquire efficiencies of the detector at different required energies. Using the well-known neutron activation formula, the neutron capture cross-sections of 164Dy(n, γ )165Dy reaction were obtained 2322 ± 140 barn at 0.0334 eV. The cross section at 0.0334 eV is 4.3%, 4.5% and 3.15% higher than the evaluated values extracted from the ENDF/B-VII.1, ROSFOND and JENDL-4.0, respectively.

Published: January 2021

Abstract
In this study, a systematic analysis of fresh and sea water fishes, poultry and their feeds and sediments was conducted using research reactor based neutron activation analysis (NAA) technique with the aim to determine elemental status with special emphasis on arsenic and chromium contamination. Sixty nine samples in different categories (fresh water fishes from three ponds, and corresponding sediments, sea water fishes from Bay of Bengal, chicken from five farms, their feeds) were analyzed through a series of NAA experiments to determine the translocations of toxic elements from feed to fish, sediments and birds and their excretion through litters. The analytical results revealed that some of the locally produced feeds for poultry and fish are highly contaminated with chromium. The flesh of both the fresh water fish and poultry are free from arsenic contamination. The sea fish contains high arsenic concentration. However, the major form of seafood arsenic as arsenobetaine that is completely harmless and its occurrence in seafood presented no human health concerns. The present study will certainly help to the Food Controlling Authority in Bangladesh to produce fish and poultry in a controlled sustainable manner and will also create public awareness.

Published: January 2021

Abstract

Ab intio calculations were carried out on the structural, elastic, and electronic properties of a newly synthesized ternary silicide superconductor, Li2IrSi3. The obtained lattice parameters show sound agreement with the experimental values, indicating the reliability of the present study. The rigid structure of Li2IrSi3 is due to the strong covalent Ir-Si and Si-Si bonding. The new compound is mechanically stable, brittle and elastically anisotropic. The relatively low value of the Poisson’s ratio for Li2IrSi3 is indicative of its high degree of directional covalent bonding.
IGAEM: Improved Genetic Algorithm based Entity Matching
Authors: Aassem Y. , Hafidi I. , Aboutabit N. 
Published: January 2021

Abstract
The presence of duplicate records is a major data quality concern in huge datasets. To detect duplicates, entity matching is used as an essential step of the data cleaning process to map records that refer to the same real-world entity. Most of proposed algorithms require labeled data in order to train a classifier. However, we cannot always obtain labeled data. In our paper we propose an unsupervised approach for entity matching problem using an improved version of genetic algorithm. We explain the main improvements added to genetic algorithm and the encoding strategy to encode partitions in the form of a chromosome. Different similarity functions are used to compute similarities between records. The obtained results prove that our proposition stands as a powerful approach in the entity matching field where it outperforms the traditional genetic algorithm based approach.
