Microwave Study of a Solar Circular Ribbon Flare
Authors: Lee Jeongwoo , White Stephen M. , Chen Xingyao , Chen Yao , Ning Hao , Li Bo , Masuda Satoshi 
Published: September 2020

Abstract
A circular ribbon flare (CRF) SOL2014-12-17T04:51 is studied using the 17/34 GHz maps from the Nobeyama Radioheliograph along with (E)UV and magnetic data from the Solar Dynamics Observatory. We report the following three findings as important features of the microwave CRF. (1) The first preflare activation comes in the form of a gradual increase of the 17 GHz flux without a counterpart at 34 GHz, which indicates thermal preheating. The first sign of nonthermal activity occurs in the form of stepwise flux increases at both 17 and 34 GHz about 4 minutes before the impulsive phase. (2) Until the impulsive phase, the microwave emission over the entire active region is in a single polarization state matching the magnetic polarity of the surrounding fields. During and after the impulsive phase, the sign of the 17 GHz polarization state reverses in the core region, which implies a magnetic breakout–type eruption in a fan–spine magnetic structure. (3) The 17 GHz flux around the time of the eruption shows quasi-periodic variations with periods of 1–2 minutes. The pre-eruption oscillation is more obvious in total intensity at one end of the flare loop, and the post-eruption oscillation, more obvious in the polarized intensity at a region near the inner spine. We interpret this transition as transfer of oscillatory power from kink mode oscillation to torsional Alfvén waves propagating along the spine field after the eruption. We argue that these three processes are interrelated and indicate a breakout process in a fan–spine structure.
Potential for Liquid Water Biochemistry Deep under the Surfaces of the Moon, Mars, and beyond

Published: September 2020

Abstract
We investigate the prospects for the past or current existence of habitable conditions deep underneath the surfaces of the Moon and Mars, as well as generic bound and free-floating extrasolar rocky objects. We construct a simple model that takes into account the thermal limits of life as well as the size, surface temperature, and relative radionuclide abundance of a given object and yields the spatial extent of the subsurface habitable region. We also investigate the constraint imposed by pressure on habitability, and show that it is unlikely to rule out the prospects for life altogether. We estimate the maximum biomass that might be sustainable in deep subsurface environments as a function of the aforementioned parameters from an energetic perspective. We find that it might be a few percent that of Earth’s subsurface biosphere, and three orders of magnitude smaller than Earth’s global biomass, under ideal circumstances. We conclude with a brief exposition of the prevalence of rocky objects with deep biospheres and methods for detecting signatures of biological activity through forthcoming missions to visit the Moon and Mars.
Detection of Coherent Pulsation Modes in the Strongly Magnetic Of?p Star NGC 1624-2 using TESS Observation

Published: September 2020

Abstract
High-cadence Transiting Exoplanet Survey Satellite (TESS) observations are promising for studies of short-term pulsational variability in magnetic O stars, which usually have long rotation periods of the order of months or years. The Of?p star NGC 1624-2 is of special interest as it possesses the strongest magnetic field measured among O stars, together with a giant magnetosphere. We detect three significant low-frequency peaks in TESS 2 minute cadence data, probably corresponding to coherent g mode pulsations. At present, this is the only magnetic O star for which pulsational variability is detected.
EFFECTS OF COLLABORATION NETWORKS ON TECHNOLOGY INNOVATION IN THE SOLAR PHOTOVOLTAIC (PV) SECTOR: A CASE STUDY OF CHINA
Authors: Liang Xinning , Lu Weisheng , Wu Zezhou 
Published: September 2020

ABSTRACT
Efficient use of energy is an essential aspect of green building development. In order to achieve a more energy efficient society, innovation of solar photovoltaic (PV) technologies is a necessity. Collaboration between innovators is regarded as important for innovation; however, the existing literature has made few attempts to investigate how a collaboration network can affect technology innovation in the context of the solar PV sector. This study aims to fill this research gap. In this study, innovation activities are categorized as exploratory innovation and exploitative innovation. A conceptual framework and a series of hypotheses are proposed from the perspectives of network structure (including direct ties, indirect ties, and network efficiency) and network composition (such as geographical proximity, institutional proximity, and technological proximity). The empirical results show that in the solar PV sector of China, collaboration networks with different kinds of structure and composition can imply diverse effects on exploratory innovation and exploitative innovation. Followed with the derived results, it can be concluded that network collaboration is not always beneficial for PV technology innovation. The research findings could convey useful information to both practitioners and policy-makers to adopt appropriate strategies for promoting effective innovation collaboration.
RELOCATABLE MODULAR BUILDINGS FOR A SHORT-TERM INTERNATIONAL EVENT: THE PYEONG-CHANG WINTER OLYMPIC GAMES
Authors: Shin Hyun Kyu , Lee Joo Sung , Jung Chan Woo , Ahn Yong Han 
Published: September 2020

ABSTRACT
Modular methods based on the use of prefabricated structures are increasingly popular for construction projects as they contribute to sustainability by reducing waste and maintenance costs as well as improving time efficiency. For short-term international events, the use of relocatable modular buildings is a potential solution to the problem of “White Elephant” structures built specially for the events that serve no useful purpose once the event is over. This paper focuses on a representative relocatable modular project created for the 2018 Winter Olympic Games in South Korea using a single case study approach to develop an in-depth understanding of the advantages and disadvantages of relocatable modular construction from a practitioner’s perspective and examine how this approach supports sustainability and the Olympic legacy. Important considerations are identified for each of the five main stages: 1) planning, 2) design and engineering, 3) manufacturing, 4) construction and 5) disassembly and reconstruction. These findings show how the use of relocatable modular facilities can be a useful approach for international events.
EVALUATING THE WEIGHTED-SUM APPROACH FOR MEASURING BUILDINGS’ ADAPTABILITY

Published: September 2020

ABSTRACT
As urban populations increase worldwide and more demands are placed on infrastructure and buildings, the topic of adaptable building design has experienced increased interest as a way to embed adaptability into the urban building stock and avoid unnecessary demolition and waste. Evaluation tools for judging building adaptability based on physical characteristics have recently been proposed. The most common approach for these tools is to use a weighted-sum of scores for different criteria. The primary purpose of this paper was to compare a weighted-sum measurement approach against a more rigorous, less abstract measurement that involved judgements about simulated adaptation projects (called an example-based approach). These measurements were performed through expert elicitation and an analytic hierarchy process (AHP) survey, where participants evaluated the relative adaptability of four case study buildings from the Clemson University campus. The results showed significant correlation between the weighted-sum approach and the example-based approach, supporting the reasonableness of using weighted-sum approaches to evaluate the adaptive potential of building designs. In addition, a separate group of experts rated adaptability of the case study buildings by providing qualitative reasons for their rankings. Unlike the other approaches, this group was not given a specific tool to guide their ratings. The qualitative data provided additional context for understanding results from the quantitative approaches.

ABSTRACTUrban building energy analysis has attracted more attention as the population living in cities increases as does the associated energy consumption in urban environments. This paper proposes a systematic bottom-up method to conduct energy analysis and assess energy saving potentials by combining dynamic engineering-based energy models, machine learning models, and global sensitivity analysis within the GIS (Geographic Information System) environment for large-scale urban buildings. This method includes five steps: database construction of building parameters, automation of creating building models at the GIS environment, construction of machine learning models for building energy assessment, sensitivity analysis for choosing energy saving measures, and GIS visual evaluation of energy saving schemes. Campus buildings in Tianjin (China) are used as a case study to demonstrate the application of the method proposed in this research. The results indicate that the method proposed here can provide reliable and fast analysis to evaluate the energy performance of urban buildings and determine effective energy saving measures to reduce energy consumption of urban buildings. Moreover, the GIS-based analysis is very useful to both create energy models of buildings and display energy analysis results for urban buildings.

AbstractWe show that the only way of changing the framing of a link by ambient isotopy in an oriented

$3$
-manifold is when the manifold has a properly embedded non-separating

$S^{2}$
. This change of framing is given by the Dirac trick, also known as the light bulb trick. The main tool we use is based on McCullough’s work on the mapping class groups of

$3$
-manifolds. We also relate our results to the theory of skein modules.
