Weak Shock Propagation with Accretion. III. A Numerical Study on Shock Propagation and Stability
Authors: Ro Stephen , Coughlin Eric R. , Quataert Eliot 
Published: June 2019

Abstract
Core-collapse supernovae span a wide range of energies, from much less than to much greater than the binding energy of the progenitor star. As a result, the shock wave generated from a supernova explosion can have a wide range of Mach numbers. In this paper, we investigate the propagation of shocks with arbitrary initial strengths in polytropic stellar envelopes using a suite of spherically symmetric hydrodynamic simulations. We interpret these results using the three known self-similar solutions for this problem: the Sedov–Taylor blast-wave describes an infinitely strong shock, and the self-similar solutions from Coughlin et al. (Papers I and II) describe a weak and infinitely weak shock (the latter being a rarefaction wave). We find that shocks, no matter their initial strengths, evolve toward either the infinitely strong or infinitely weak self-similar solutions at sufficiently late times. For a given density profile, a single function characterizes the long-term evolution of a shock’s radius and strength. However, shocks with strengths near the self-similar solution for a weak shock (from Paper I) evolve extremely slowly with time. Therefore, the self-similar solutions for infinitely strong and infinitely weak shocks are not likely to be realized in low-energy stellar explosions, which will instead retain a memory of the shock strength initiated in the stellar interior.
Tilt Dependence of Alignment in Accretion Disks Subjected to Lense–Thirring Torques
Authors: Hawley John F. , Krolik Julian H. 
Published: June 2019

Abstract
We consider the effects of black hole tilt on accretion disk alignment, studying three initial black hole tilts, 6°, 12°, and 24°, with both magnetohydrodynamic and (inviscid) hydrodynamic evolution. In a number of ways, but not all, the dynamics are homologous in the sense that the alignment fronts resulting from different initial tilts are very similar when analyzed in terms of the fraction of the initial tilt angle. Even when the initial misalignment is 24°, which, for the sound speed studied, is 4 vertical scale heights at the disk fiducial radius, the surface density remains a smooth function of radius, i.e., we find no examples in which the disk inner aligned and outer misaligned regions separate, or “break.”
Polarization of Astrophysical Events with Precessing Jets

Published: June 2019

Abstract
A central compact object (CCO; e.g., a black hole) with an accretion disk has been suggested as the common central engine of various astrophysical phenomena, such as gamma-ray bursts (GRBs), tidal disruption events (TDEs), and active galactic nuclei (AGNs). A jet powered by such a system might precess due to the misalignment of the angular momenta of the CCO and accretion disk. Some quasiperiodic behaviors observed in the light curves of these phenomena can be well interpreted within the framework of a precessing jet model. In this paper, we study the emission polarization of precessing jets in these three kinds of phenomena. The polarization angle also shows a gradual change for the synchrotron emission in both the random and toroidal magnetic field configurations with the precessing jet, while it can only change abruptly by 90° for the nonprecessing top-hat jet. Polarization properties are periodic due to the assumptions made in our model. The polarization observations are crucial to confirm the precession nature of jets in GRBs, TDEs, and AGNs.
A Two Forceps Technique For Approaching Tractional Diabetic Membranes
Authors: Kaden Talia R. , Engelbert Michael 
Published: June 2019

BACKGROUND AND OBJECTIVE:
To describe a two-forceps bimanual approach for complex diabetic detachments.

PATIENTS AND METHODS:
Curved scissors were used to create a zone of decreased resistance within a thick fibrovascular membrane in a previously vitrectomized patient. Using two forceps, the linear defect was propagated into the periphery in a direction tangential to the retina. The tissue was repeatedly regrasped at the leading edge of the propagating tear, allowing for progressive separation of the hyaloid from the retinal surface.

RESULTS:
Separation of the diabetic membrane and hyaloid from the retinal surface in a previously vitrectomized patient.

CONCLUSION:
The authors describe a two-forceps approach for dense fibrovascular proliferation in the setting of persistently attached cortical vitreous that may be employed in cases of severe diabetic retinopathy with traction and fibrovascular membranes, even after previous vitrectomy.

A cobertura midiática dos crimes de violência contra a mulher :preconceito e silenciamentos
Authors: Belisário Katia Maria , Reis Anna Caroline Magalhães 
Published: June 2019

De modo geral, jornalistas no Brasil, e também em outras partes do mundo, mostram uma tendência à naturalização dos crimes de violência contra a mulher. Este artigo pretende mostrar exemplos de como essa naturalização ocorre a partir de reportagens que tratam do crime de um estupro coletivo de uma jovem de 16 anos, ocorrido no Rio de Janeiro em 2016, publicado no portal G1 do Brasil. Também mostramos a cobertura misógina do New York Times sobre um estupro coletivo ocorrido no Texas em 2012. As perguntas de pesquisa que buscamos responder são : Por que a mídia tende a naturalizar os crimes de violência contra a mulher ? Quais silêncios envolvidos ? De que forma podemos trabalhar as questões de gênero com os futuros profissionais para evitar a misoginia ? A metodologia utilizada é a análise do discurso das reportagens do portal G1, comparadas à cobertura do New York Times.
Entre a concessão e a adversidade: orações introduzidas por <i>aunque</i> no espanhol sob o viés funcionalista
Authors: Garcia Talita Storti , Felipe Mariana Alves Machado Pelegrini 
Published: June 2019

Este trabalho investiga as orações do espanhol falado introduzidas por aunque, juntor que, de acordo com os compêndios gramaticais, na língua espanhola, pode assinalar uma relação concessiva ou adversativa. Sob a perspectiva da teoria da gramática discursivo-funcional (Hengeveld & Mackenzie, 2008), pretende-se averiguar como o fenômeno da sobreposição semântica entre concessão e adversidade é concebido e, de maneira específica, investigar em quais níveis e camadas do modelo essa sobreposição ocorre. Os resultados mostram que os casos duvidosos postulados pela perspectiva tradicional se dão no domínio interpessoal, quando constituem funções retóricas e funções interacionais.

Abstract
Intracellular viral RNAs are recognized by the RIG-I–like receptors (RLRs), which signal through the mitochondrial antiviral signaling protein MAVS. MAVS recruits and activates TBK1 kinase, which further phosphorylates and activates the transcription factor IRF3, leading to the induction of type I IFN and downstream antiviral genes. We identified human nucleus accumbens–associated 1 (NAC1), a member of the BTB/POZ family, as a bridge for MAVS and TBK1 that positively regulates the RLR-mediated induction of type I IFN. Overexpression or knockdown of NAC1 could, respectively, enhance or impair Sendai virus–triggered activation of TBK1 and IRF3, as well as induction of IFN-β. NAC1 also significantly boosted host antiviral responses against multiple RNA viruses. NAC1 was able to interact with MAVS and TBK1 upon viral infection. The BTB/POZ domain (aa 1–133) of NAC1 interacted with MAVS, and the remainder of NAC1 bound to TBK1. Furthermore, NAC1 could promote the recruitment of TBK1 to MAVS. In contrast, knockdown of NAC1 attenuated the interaction between TBK1 and MAVS. Collectively, our study characterizes NAC1 as an important component of RLR-mediated innate immune responses and uncovers a previously unrecognized function of the BTB/POZ family proteins.

Published: June 2019

A produção monográfica é um meio de inserir o aluno da graduação na pesquisa científica, tornando-o responsável por gerar conhecimento e ser sujeito ativo no seu processo de formação (Severino, 2007; Demo, 2011). A problemática desta pesquisa consiste no seguinte questionamento: que significados são atribuídos pelos estudantes à elaboração da monografia? Esta investigação justifica-se pela inexistência de pesquisas que tratem das percepções dos alunos de Secretariado Executivo sobre o tema, sendo relevante conhecer tais percepções, uma vez que a monografia não é um componente obrigatório para a conclusão da graduação na área, e estudos que evidenciem tais percepções podem contribuir para maior interesse dos estudantes de graduação na pesquisa científica. O objetivo geral consiste em compreender o significado da produção monográfica para os egressos do curso de bacharelado em Secretariado Executivo da Universidade Federal do Ceará [UFC]. No que se refere aos aspectos metodológicos, trata-se de uma pesquisa qualitativa e descritiva. A técnica de coleta de dados empregada foi questionário, e a análise foi realizada por meio da análise de conteúdo. A abordagem teórica contempla estudos da Educação que discutem a formação acadêmica e os estudos sobre pesquisa em Secretariado. Os sujeitos apontaram dificuldades de ordem pessoal e institucional, mas estas parecem não comprometer a produção monográfica. Concluiu-se que o trabalho monográfico impacta positivamente na satisfação dos estudantes, contribuindo tanto para o seu desenvolvimento intelectual quanto pessoal. Ademais, esses trabalhos fomentam e enriquecessem as pesquisas na área secretarial.

Published: June 2019

AbstractSmall interfering RNA (siRNA) is considered a highly specific and potent biotherapeutic that holds tremendous potential for the treatment of various diseases. The clinical translation of siRNA is, however, greatly impeded by the lack of safe and efficient delivery vehicles in vivo. Here, the development of selective cell penetrating peptide (CPP33)‐functionalized chimeric lipopepsomes (CPP33‐CLP) for efficient encapsulation and selective delivery of polo‐like kinase 1 specific siRNA (siPLK1) to orthotopic A549 human lung tumor in vivo is reported. Interestingly, siRNA is tightly encapsulated into CPP33‐CLP with a superb encapsulation efficiency of over 95% owing to the thick strong electrostatic interactions. Notably, siPLK1‐loaded CPP33‐CLP (siPLK1‐CPP33‐CLP) is selectively internalized by A549 human lung cancer cells, efficiently escapes from endosomes, and swiftly releases siRNA into the cytoplasm, affording a significant sequence‐specific gene silencing in vitro. Moreover, siPLK1‐CPP33‐CLP exhibits prolonged blood circulation, enhanced tumor accumulation, effective suppression of tumor growth, and considerably elevated survival time of orthotopic A549 human lung tumor‐bearing nude mice. These chimeric lipopepsomes appear as an attractive and potent nanoplatform for safe and targeted siRNA delivery.
Anisotropic Thermal Boundary Resistance across 2D Black Phosphorus: Experiment and Atomistic Modeling of Interfacial Energy Transport

Published: June 2019

AbstractInterfacial thermal boundary resistance (TBR) plays a critical role in near‐junction thermal management of modern electronics. In particular, TBR can dominate heat dissipation and has become increasingly important due to the continuous emergence of novel nanomaterials with promising electronic and thermal applications. A highly anisotropic TBR across a prototype 2D material, i.e., black phosphorus, is reported through a crystal‐orientation‐dependent interfacial transport study. The measurements show that the metal–semiconductor TBR of the cross‐plane interfaces is 241% and 327% as high as that of the armchair and zigzag direction‐oriented interfaces, respectively. Atomistic ab initio calculations are conducted to analyze the anisotropic and temperature‐dependent TBR using density functional theory (DFT)‐derived full phonon dispersion relation and molecular dynamics simulation. The measurement and modeling work reveals that such a highly anisotropic TBR can be attributed to the intrinsic band structure and phonon spectral transmission. Furthermore, it is shown that phonon hopping between different branches is important to modulate the interfacial transport process but with directional preferences. A critical fundamental understanding of interfacial thermal transport and TBR–structure relationships is provided, which may open up new opportunities in developing advanced thermal management technology through the rational control over nanostructures and interfaces.

AbstractSince the first report of the green emission of 2D all‐inorganic CsPb2Br5, its bandgap and photoluminescence (PL) origin have generated intense debate and remained controversial. After the discovery that PL centers occupy only specific morphological structures in CsPb2Br5, a two‐step highly sensitive and noninvasive optical technique is employed to resolve the controversy. Same‐spot Raman‐PL as a static property–structure probe reveals that CsPbBr3 nanocrystals are contributing to the green emission of CsPb2Br5; pressure‐dependent Raman‐PL with a diamond anvil cell as a dynamic probe further rules out point defects such as Br vacancies as an alternative mechanism. Optical absorption under hydrostatic pressure shows that the bandgap of CsPb2Br5 is 0.3–0.4 eV higher than previously reported values and remains nearly constant with pressure up to 2 GPa in good agreement with full‐fledged density functional theory (DFT) calculations. Using ion exchange of Br with Cl and I, it is further proved that CsPbBr3−x
Xx
(X = Cl or I) is responsible for the strong visible PL in CsPb2Br5−x
Xx
. This experimental approach is applicable to all PL‐active materials to distinguish intrinsic defects from extrinsic nanocrystals, and the findings pave the way for new design and development of highly efficient optoelectronic devices based on all‐inorganic lead halides.

AbstractCurrently, photovoltaic/electroluminescent (PV/EL) perovskite bifunctional devices (PBDs) exhibit poor performance due to defects and interfacial misalignment of the energy band. Interfacial energy‐band engineering between the perovskite and hole‐transport layer (HTL) is introduced to reduce energy loss, through adding corrosion‐free 3,3′‐(2,7‐dibromo‐9H‐fluorene‐9,9‐diyl) bis(n,n‐dimethylpropan‐1‐amine) (FN‐Br) into a HTL free of lithium salt. This strategy can turn the n‐type surface of perovskite into p‐type and thus correct the misalignment to form a well‐defined N–I–P heterojunction. The tailored PBD achieves a high PV efficiency of up to 21.54% (certified 20.24%) and 4.3% EL external quantum efficiency. Free of destructive additives, the unencapsulated devices maintain >92% of their initial PV performance for 500 h at maximum power point under standard air mass 1.5G illumination. This strategy can serve as a general guideline to enhance PV and EL performance of perovskite devices while ensuring excellent stability.

Published: June 2019

AbstractA supercapacitor made from organic and nature‐based materials, such as conductive polymers (PEDOT:PSS), nanocellulose, and an the organic dye molecule (alizarin), is demonstrated. The dye molecule, which historically was extracted from the roots of the plantrubia tinctorum, is here responsible for the improvement in energy storage capacity, while the conductive polymer provides bulk charge transport within the composite electrode. The forest‐based nanocellulose component provides a mechanically strong and nonporous network onto which the conductive polymer self‐organizes. The electrical and electrochemical properties of the material composition are investigated and prototype redox‐enhanced supercapacitor devices with excellent specific capacitance exceeding 400 F g−1and an operational stability over >1000 cycles are demonstrated. This new class of supercapacitors, which in part are based on organic materials from plants, represents an important step toward a green and sustainable energy technology.
Chemical Bonding Effect on the Incorporation and Conduction of Interstitial Oxide Ions in Gallate Melilites

Published: June 2019

AbstractThe ability to incorporate high content of interstitial oxygen ions (Oi) in La1+xSr1‐xGa3O7+0.5x melilite owing to the good size match between La3+ and Sr2+ ions is well documented. Here, the complete substitution of Sr2+ by Pb2+ lone‐pair cations results in a significant loss of this ability, even though Sr2+ and Pb2+ have almost the same effective ionic radius. To explore the fundamental mechanism underlying this result, density functional theory (DFT) calculations are performed on both the LaSrGa3O7‐based and LaPbGa3O7‐based materials, revealing a new chemical bonding effect on the incorporation of mobile oxygen interstitial defects in melilites. For LaSrGa3O7‐based melilites, the interstitial oxygens have cooperatively weak antibonding interactions with the framework oxygen atoms (Of). This antibonding Oi‐Of interaction pushes Oi toward a 3‐linked Ga ion, enhancing the covalent bonding between this Ga ion and Oi. In addition, the antibonding Oi–Of interaction makes the oxygen interstitial defects and framework atoms highly active, benefiting the migration of defects. In contrast, for LaPbGa3O7‐based materials, the 6s2 electrons of Pb2+ point toward the c‐axis and form antibonding with framework O2−. This antibonding projects into the tunnel void, thereby directly hindering the entrance of interstitial oxygen atoms into the pentagonal rings.
