Isomers in Interstellar Environments. I. The Case of Z- and E-cyanomethanimine
Authors: Shingledecker Christopher N. , Molpeceres Germán , Rivilla Víctor M. , Majumdar Liton , Kästner Johannes 
Published: July 2020

Abstract
In this work, we present the results of our investigation into the chemistry of Z- and E-cyanomethanimine (HNCHCN), both of which are possible precursors to the nucleobase adenine. Ab initio quantum chemical calculations for a number of reactions with atomic hydrogen were carried out. We find that the reaction H + Z/E-HNCHCN leading both to H-addition as well as H2-abstraction proceed via similar short-range barriers with bimolecular rate coefficients on the order of ∼10−17 cm3 s−1. These results were then incorporated into astrochemical models and used in simulations of the giant molecular cloud G+0.693. The calculated abundances obtained from these models were compared with previous observational data and found to be in good agreement, with a predicted [Z/E] ratio of ∼3—somewhat smaller than the previously derived value of 6.1 ± 2.4. We find that the [Z/E] ratio in our simulations is due mostly to ion-molecule destruction rates driven by the different permanent dipoles of the two conformers. Based on these results, we propose a general rule-of-thumb for estimating the abundances of isomers in interstellar environments, which we call the “relative dipole principle.”
A Comparative Study of Long and Short GRBs. II. A Multiwavelength Method to Distinguish Type II (Massive Star) and Type I (Compact Star) GRBs
Authors: Li Ye , Zhang Bing , Yuan Qiang 
Published: July 2020

Abstract
Gamma-ray bursts (GRBs) are empirically classified as long-duration GRBs (LGRBs, >2 s) and short-duration GRBs (SGRBs, <2 s). Physically they can be grouped into two distinct progenitor categories: those originating from collapse of massive stars (also known as Type II) and those related to mergers of compact stars (also known as Type I). Even though most LGRBs are Type II and most SGRBs are Type I, the duration criterion is not always reliable to determine the physical category of a certain GRB. Based on our previous comprehensive study of the multiwavelength properties of long and short GRBs, here we utilize the naive Bayes method to physically classify GRBs as Type I and Type II GRBs based on multiwavelength criteria. It results in a 0.5% training error rate and a 1% test error rate. Moreover, there is a gap [−1.2, −0.16] in the distribution of the posterior odds,

, the Type II to Type I probability ratio. Therefore, we propose to use

as the parameter to classify GRBs into Type I (<0) or Type II (>0). The only confirmed Type I GRB, GRB 170817A, has log

. According to this criterion, the supernova-less long GRBs 060614 and 060505 belong to Type I, and two controversial short GRBs 090426 and 060121 belong to Type II.
Spicule Jets in the Solar Atmosphere Modeled with Resistive MHD and Thermal Conduction

Published: July 2020

Abstract
Using numerical simulations, we study the effects of magnetic resistivity and thermal conductivity in the dynamics and properties of solar jets with characteristics of Type II spicules and cool coronal jets. The dynamic evolution of the jets is governed by the resistive MHD equations with thermal conduction along the magnetic field lines on a 2.5D slice. The magnetic field configuration consists of two symmetric neighboring loops with opposite polarity, used to support reconnection and followed by the plasma jet formation. In total, 10 simulations were carried out with different values of resistivity and thermal conductivity that produce jets with different morphological and thermal properties we quantify. We find that an increase in magnetic resistivity does not produce significant effects on the morphology, velocity, and temperature of the jets. However, thermal conductivity affects both temperature and morphology of the jets. In particular, thermal conductivity causes jets to reach greater heights and increases the temperature of the jet-apex. Also, heat flux maps indicate the jet-apex and corona interchange energy more efficiently than the body of the jet. These results could potentially open a new avenue for plasma diagnostics in the Sun’s atmosphere.
Gas Dynamics of the Nickel-56 Decay Heating in Pair-instability Supernovae
Authors: Chen Ke-Jung , Woosley S. E. , Whalen Daniel J. 
Published: July 2020

Abstract
Very massive 140–260 M
⊙ stars can die as highly energetic pair-instability supernovae (PI SNe) with energies of up to 100 times those of core-collapse SNe that can completely destroy the star, leaving no compact remnant behind. These explosions can synthesize 0.1–30 M
⊙ of radioactive 56Ni, which can cause them to rebrighten at later times when photons due to 56Ni decay diffuse out of the ejecta. However, heat from the decay of such large masses of 56Ni could also drive important dynamical effects deep in the ejecta that are capable of mixing elements and affecting the observational signatures of these events. We have now investigated the dynamical effect of 56Ni heating on PI SN ejecta with high-resolution two-dimensional hydrodynamic simulations performed with the CASTRO code. We find that expansion of the hot 56Ni bubble forms a shell at the base of the silicon layer of the ejecta ∼200 days after the explosion but that no hydrodynamical instabilities develop that would mix 56Ni with the 28Si/16O-rich ejecta. However, while the dynamical effects of 56Ni heating may be weak they could affect the observational signatures of some PI SNe by diverting decay energy into internal expansion of the ejecta at the expense of rebrightening at later times.

Abstract
A large number of observations from the Parkes 64 m diameter radio telescope, recorded with high time resolution, are publicly available. We have reprocessed all of the observations obtained during the first four years (from 1997–2001) of the Parkes Multibeam Receiver system in order to identify transient events, and have built a database that records the 568,736,756 pulse candidates generated during this search. We have discovered a new fast radio burst (FRB), FRB 010305, with a dispersion measure (DM) of 350 ± 5 cm−3 pc and explored why so few FRBs have been discovered in data prior to 2001. After accounting for the dispersion smearing across the channel bandwidth and the sky regions surveyed, the number of FRBs is found to be consistent with model predictions. We also present five single pulse candidates from unknown sources, but with Galactic DMs. We extract a diverse range of sources from the database, which can be used, for example, as a training set of data for new software being developed to search for FRBs in the presence of radio frequency interference.

Published: July 2020

Il s’agit ici d’interroger la notion d’environnement au regard de la question des ontologies. Comment façonnent-elles notre réel ? Comment, en créant de nouveaux cadres ontologiques, pouvons-nous produire de nouveaux « environnements » ? Pour cela nous proposons l’élaboration d’un outil onto-fictionnel basé sur la construction d’un manuel de traduction des ontologies existantes et l’élaboration d’un vocabulaire typologique à travers l’analyse d’objets participant à la matérialité de l’environnement. Enfin, nous nous attachons à définir les ontofictions et ce qu’elles ont pour objectif de produire comme capacités descriptives et perceptives.
A REVIEW OF CLIMATE CHANGE ADAPTIVE MEASURES IN ARCHITECTURE WITHIN TEMPERATE CLIMATE ZONES
Authors: Poulsen Mikkel , Lauring Michael , Brunsgaard Camilla 
Published: July 2020

ABSTRACT
Since a large portion of greenhouse gases are emitted by the building sector, there has been a push towards sustainable low energy architecture, which could help mitigate the effects of climate change. Although climate change is considered inevitable, adaptive measures must be taken in the field of architecture to alleviate its impact. Creating an overview of the state of the art in the field of architecture as it adapts to climate change will help identify the problems and possibilities of architectural adaptation.
The aim must be to create buildings that are as suitable to the current climate as they are to the climate of the future and maintain an ability to resist the impacts of climate change; this ability to resist potential change is defined as adaptive capacity. It is challenging to reconcile the energy requirements for contemporary buildings with rising temperatures and extreme weather in temperate climate zones. The literature on the subject is explored through iterative searches in scientific databases.
In discussions about the possible adaptations to climate change, there needs to be a focus on human adaptation facilitated by architecture and the built environment’s utilization and support of ecosystem services in adaptation strategies, since the scope of climate change reaches beyond the singular building. There are plenty of strategies and technologies from which to draw but little focus on how these should support the design of a building and its inhabitants. In the future it will be necessary to look at the adaptive capacity of a building itself and how the building can benefit its surroundings.

Published: July 2020

ABSTRACTThe possibility of the use of recycled aggregates from the construction industry in green concrete production is of increasing importance to reduce the negative environmental impact associated with construction and demolition wastes. The objective of this study is to investigate the effect of recycled concrete aggregate (RCA) quality on the properties of hardened concrete properties such as compressive strength, splitting tensile strength, density, water absorption capacity and porosity accessible to water. The RCA used in this study was obtained from the crushing of waste concrete with two different compressive strengths (LRCA obtained from the crushing of waste concrete having compressive strengths below 30 MPa and HRCA obtained from the crushing of waste concrete having compressive strengths above 30 MPa). The natural coarse limestone aggregate was 100% replaced with coarse LRCA and HRCA. As a result of the study, the use of 100% HRCA and %100 LRCA instead of limestone coarse aggregate in the concrete adversely affected its mechanical and physical properties. In addition, HRCA showed better performance in terms of compressive strength, tensile strength, water absorption and porosity compared to the use of LRCA. Furthermore, the percentage of adhered mortar on the surface of LRCA and HRCA was analyzed using a computerized micro tomography device, and it was found that the percentages of attached mortar and aggregates are 61% and 35.5% for LRCA, whilst the attached mortar and aggregate contents for HRCA are 45.9% and 53.7%, respectively.

Authors: Zhang Rong , Li Yingchun , Wang Hongtao , Zhu Ke , Zhang Guojun 
Published: July 2020

IntroductionThis study was undertaken to examine the anticancer effects of the natural product rhein on human leukaemia cells.Material and methodsCell viability was determined by MTT assay. Immunofluorescence staining, DAPI, AO/EB, and annexin V/PI staining were used for the detection of apoptosis. qRT-PCR analysis was used to examine protein expression. Western blot analysis was used to determine protein expression.ResultsThe results revealed that rhein caused a significant (p < 0.05) and dose-dependent decrease in the viability of AML-193 leukaemia cells. It was also revealed that rhein caused morphological changes such as cell rounding in rhein-treated AML-193 cells. The DAPI and AO/EB staining showed that rhein caused remarkable changes in the nuclear morphology of the AML-193 cells, characteristic of apoptosis. The percentage of apoptosis was found to be 3.12%, 14.80%, 30.31%, and 60.85% at the concentrations of 0, 3.5, 7, and 14 µM of rhein, respectively. The expression of Bax, cleaved caspase-3, 9, and cleaved PARP increased concentration dependently, while the expression of Bcl-2 decreased. The effects of rhein were also examined on 11 different miRs, and it was found that rhein specifically and significantly (p < 0.05) inhibited the expression of miR-27. Additionally, inhibition of miR-27 resulted in the decrease of AML-193 viability and upregulation of Cullin 5 (CUL5).ConclusionsTaken together, rhein triggers apoptosis in leukaemia cells and modulates the miR-27/CUL5 axis. As such, rhein may prove to be beneficial in the treatment of leukaemia.
Re-excision within a radius of 2 cm in patients with melanoma of the skin – sufficient for local oncological radicalness

Published: July 2020

IntroductionMalignant melanoma is one of the most malignant tumours in the human body. Radical re-excision of the tumour bed is a principal part of its surgical treatment. We aim to test the hypothesis that the re-excision with a 2 cm margin in all directions to the scar from the previous biopsy of the primary tumour provides sufficient local control in patients with this disease.Material and methodsThis is a prospective descriptive study using STROBE methods, including all 151 patients with malignant melanoma of the skin, diagnosed and treated at the Department of Plastic, Reconstructive, and Aesthetic Surgery, Dr Georgi Stranski University Hospital, Medical University of Pleven, Bulgaria, in the period 2012–2016. Twenty-one cases were omitted from the study during the observation period due to lack of sufficient data. The re-excision was mainly within 2 cm margins in all directions to the scar from the previous biopsy of the primary tumour.ResultsData of all 130 patients with malignant skin melanoma, diagnosed and treated at our single large centre, were prospectively registered and analysed. These were 67 male and 63 female patients with a mean age at diagnosis of 61.6 years (range: 17–91 years). Using the re-excision within 2 cm margins, we identified only 1 (0.77%) patient with a histologically confirmed residual tumour in the re-excised flap. Local recurrence was observed in 13 (10%) patients.ConclusionsRe-excision with a 2 cm margin is sufficient to achieve local surgical radicalness in the treatment of this disease without compromising oncological survival.
