Abstract
The relativistic jets created by some active galactic nuclei are important agents of AGN feedback. In spite of this, our understanding of what produces these jets is still incomplete. X-ray observations, which can probe the processes operating in the central regions in the immediate vicinity of the supermassive black hole, the presumed jet launching point, are potentially particularly valuable in illuminating the jet formation process. Here, we present the hard X-ray NuSTAR observations of the radio-loud quasar 4C 74.26 in a joint analysis with quasi-simultaneous, soft X-ray Swift observations. Our spectral analysis reveals a high-energy cutoff of

keV and confirms the presence of ionized reflection in the source. From the average spectrum we detect that the accretion disk is mildly recessed, with an inner radius of R
in = 4–180 R
g. However, no significant evolution of the inner radius is seen during the three months covered by our NuSTAR campaign. This lack of variation could mean that the jet formation in this radio-loud quasar differs from what is observed in broad-line radio galaxies.

Abstract
We report the results of three Chandra observations covering most of the extent of the TeV γ-ray source HESS J1616–508 and a search for a lower-energy counterpart to this source. We detect 56 X-ray sources, 37 of which have counterparts at lower frequencies, including a young massive star cluster, but none of them appear to be a particularly promising counterpart to the TeV source. The brightest X-ray source, CXOU J161423.4–505738, with a flux F
0.5–7 keV ≈ 5 × 10−13 erg cm−2 s−1, has a hard spectrum that is well fit by a power-law model with a photon index Γ = 0.2 ± 0.3 and is a likely intermediate polar CV candidate. No counterparts of this source were detected at other wavelengths. CVs are not known to produce extended TeV emission, and the source is also largely offset (19′) from HESS J1616–508, making them unlikely to be associated. We have also set an upper limit on the X-ray flux of PSR J1614–5048 in the 0.5–8 keV band (F
0.5–8 keV < 5 × 10−15 erg cm−2 s−1 at a 90% confidence level). This makes PSR J1614–5048 one of the least X-ray-efficient pulsars known, with an X-ray efficiency

. We find no evidence supporting the association between the pulsar and the TeV source. We rule out a number of X-ray sources as possible counterparts to the TeV emission and do not find a plausible counterpart among the other sources. Lastly, we discuss the possible relation of PSR J1617–5055 to HESS J1616–508 in light of the new observations.
The Hottest Hot Jupiters May Host Atmospheric Dynamos
Authors: Rogers T. M. , McElwaine J. N. 
Published: May 2017

Abstract
Hot Jupiters have proven themselves to be a rich class of exoplanets that test our theories of planetary evolution and atmospheric dynamics under extreme conditions. Here, we present three-dimensional magnetohydrodynamic simulations and analytic results that demonstrate that a dynamo can be maintained in the thin, stably stratified atmosphere of a hot Jupiter, independent of the presumed deep-seated dynamo. This dynamo is maintained by conductivity variations arising from strong asymmetric heating from the planets’ host star. The presence of a dynamo significantly increases the surface magnetic field strength and alters the overall planetary magnetic field geometry, possibly affecting star–planet magnetic interactions.

Abstract
We present spatially resolved ALMA observations of the CO

emission line in two massive galaxies at z = 2.5 on the star-forming main sequence. Both galaxies have compact dusty star-forming cores with effective radii of

and

in the 870 μm continuum emission. The spatial extent of star-forming molecular gas is also compact with

and

, but more extended than the dust emission. Interpreting the observed position–velocity diagrams with dynamical models, we find the starburst cores to be rotation dominated with the ratio of the maximum rotation velocity to the local velocity dispersion of

(

km s−1) and

(

km s−1). Given that the descendants of these massive galaxies in the local universe are likely ellipticals with

nearly an order of magnitude lower, the rapidly rotating galaxies would lose significant net angular momentum in the intervening time. The comparisons among dynamical, stellar, gas, and dust mass suggest that the starburst CO-to-H2 conversion factor of

(K km s−1 pc−2)−1 is appropriate in the spatially resolved cores. The dense cores are likely to be formed in extreme environments similar to the central regions of local ultraluminous infrared galaxies. Our work also demonstrates that a combination of medium-resolution CO and high-resolution dust continuum observations is a powerful tool for characterizing the dynamical state of molecular gas in distant galaxies.
A Statistical Comparative Planetology Approach to the Hunt for Habitable Exoplanets and Life Beyond the Solar System
Authors: Bean Jacob L. , Abbot Dorian S. , Kempton Eliza M.-R. 
Published: May 2017

Abstract
The search for habitable exoplanets and life beyond the solar system is one of the most compelling scientific opportunities of our time. Nevertheless, the high cost of building facilities that can address this topic and the keen public interest in the results of such research requires rigorous development of experiments that can deliver a definitive advancement in our understanding. Most work to date in this area has focused on a “systems science” approach of obtaining and interpreting comprehensive data for individual planets to make statements about their habitability and the possibility that they harbor life. This strategy is challenging because of the diversity of exoplanets, both observed and expected, and the limited information that can be obtained with astronomical instruments. Here, we propose a complementary approach that is based on performing surveys of key planetary characteristics and using statistical marginalization to answer broader questions than can be addressed with a small sample of objects. The fundamental principle of this comparative planetology approach is maximizing what can be learned from each type of measurement by applying it widely rather than requiring that multiple kinds of observations be brought to bear on a single object. As a proof of concept, we outline a survey of terrestrial exoplanet atmospheric water and carbon dioxide abundances that would test the habitable zone hypothesis and lead to a deeper understanding of the frequency of habitable planets. We also discuss ideas for additional surveys that could be developed to test other foundational hypotheses in this area.
“Timely” Publication: The Racialized Context of Edith Wharton's “Bunner Sisters”
Authors: Li Jin 
Published: May 2017

Abstract
While a number of critics frequently refer to the fact that “Bunner Sisters” was written in 1892 but published in 1916, few have explored the possible reasons behind the late publication. In the class discussion of “Bunner Sisters,” my students demonstrated their interest in the tragic destiny of Ann Eliza and Evelina. Despite the fact that they were informed of the novella's publishing history and were guided to heed the negative textual representations about Herman Ramy, their course papers on “Bunner Sisters” either analyze much-researched themes, such as the inutility of self-renunciation and the Bunner sisters' confusing of Ramy's literacy with moral integrity, or justify the relevance of a critical theory (reader-response theory) to the interpreting of the novella. This article argues that an examination of the race context of the novella indicates Wharton's adherence to the dominant political sentiments of her times, and that the publication of “Bunner Sisters” in 1916 after the breakout of World War I can be viewed as a “timely” one.

Background The prevalence of flap necrosis after palatoplasty in patients with cleft palate. The prevalence of mucoperiosteal flap necrosis after palatoplasty remains unknown, and this complication is rare. This event is highly undesirable for both the patient and the surgeon. We present here a new scale to evaluate the degree of hypoplasia of the palate and identify patients with cleft palate at high risk for the development of this complication.
Methods In this case series, a 20-year retrospective analysis (1994–2014) identified patients from our records (medical records and screening day registries) with nonsyndromic cleft palate who underwent operations at 3 centers. All of these patients underwent operations using 2-flap palatoplasty and also underwent a physical examination with photographs and documentation of the presence of palatal flap necrosis after primary palatoplasty.
Results Palatal flap necrosis was observed in 4 cases out of 1,174 palatoplasties performed at these centers. The observed prevalence of palatal flap necrosis in these groups was 0.34%.
Conclusions The prevalence of flap necrosis can be reduced by careful preoperative planning, and prevention is possible. The scale proposed here may help to prevent this complication; however, further studies are necessary to validate its utility.
Validation of a Cognitive Task Simulation and Rehearsal Tool for Open Carpal Tunnel Release
Authors: Paro John A. M. , Luan Anna , Lee Gordon K. 
Published: May 2017

Background Carpal tunnel release is one of the most common surgical procedures performed by hand surgeons. The authors created a surgical simulation of open carpal tunnel release utilizing a mobile and rehearsal platform app. This study was performed in order to validate the simulator as an effective training platform for carpal tunnel release.
Methods The simulator was evaluated using a number of metrics: construct validity (the ability to identify variability in skill levels), face validity (the perceived ability of the simulator to teach the intended material), content validity (that the simulator was an accurate representation of the intended operation), and acceptability validity (willingness of the desired user group to adopt this method of training). Novices and experts were recruited. Each group was tested, and all participants were assigned an objective score, which served as construct validation. A Likert-scale questionnaire was administered to gauge face, content, and acceptability validity.
Results Twenty novices and 10 experts were recruited for this study. The objective performance scores from the expert group were significantly higher than those of the novice group, with surgeons scoring a median of 74% and medical students scoring a median of 45%. The questionnaire responses indicated face, content, and acceptability validation.
Conclusions This mobile-based surgical simulation platform provides step-by-step instruction for a variety of surgical procedures. The findings of this study help to demonstrate its utility as a learning tool, as we confirmed construct, face, content, and acceptability validity for carpal tunnel release. This easy-to-use educational tool may help bring surgical education to a new—and highly mobile—level.

De la « Chronique du lundi » (1891-1900) au Journal de Françoise (1902-1909) : hybridité des formes et des écritures dans l’oeuvre de Françoise
Authors: Rizzuto Liliana 
Published: May 2017

L’oeuvre de la journaliste Françoise a été maintes fois étudiée, mais jamais sous l’angle de ses supports. De la chronique à la revue, en passant par le recueil, la somme des publications de l’écrivaine donne à voir les différentes appropriations possibles de la forme médiatique, en même temps que la problématique catégorisation des textes en fonction de leur seul mode de diffusion. Alors que la « Chronique du lundi », malgré sa mise en recueil, apparaît comme un genre dépendant du contexte journalistique, le Journal de Françoise se lit sinon comme un livre, du moins comme une anthologie. L’hybridité et les contradictions qui caractérisent les textes de Françoise dévoilent différentes facettes de l’auteure, ni journaliste littéraire, ni écrivaine journalistique, mais femme de lettres bien de son temps.
De l’éditeur au lecteur : De Marque et la distribution du livre numérique
Authors: Grenier Joanie 
Published: May 2017

En 2008, le Québec fait son entrée dans le marché du livre numérique. Cette année-là, l’Association nationale des éditeurs de livres du Québec (ANEL) s’associe avec l’entreprise De Marque pour créer l’Entrepôt numérique (www.entrepotnumerique.com), une plateforme de distribution de livres numériques québécois. En tant que concepteur technologique et gestionnaire de cette plateforme, De Marque incarne un nouveau profil de distributeur, 100 % numérique. Mais quel est, au juste, le rôle d’un distributeur numérique? Concrètement, comment celui-ci s’assure-t-il que le fichier d’un livre numérique circule de l’éditeur qui l’a créé au lecteur qui l’achètera? Que se passe-t-il, en coulisses, lorsque l’acheteur en question clique sur le bouton « Acheter » sur le site d’un libraire? Notre article vise à répondre à ces questions qui soulèvent des concepts et des enjeux technologiques, économiques et culturels complexes. Pour y répondre, nous prendrons appui sur le cas particulier du distributeur De Marque et de la plateforme générique de distribution qu’il a développée, Cantook (ou, lorsque l’exemple québécois s’impose, l’Entrepôt numérique).
ICAM‐1‐Expressing Extracellular Vesicles Enable Sequential Delivery Barrier‐Breaking and Microenvironment Modulating for Glioblastoma Stem Cell Inhibition

Published: October 2024

AbstractGlioma stem‐like cell (GSC) inhibition is a promising strategy for glioblastoma therapy. However, it is hampered by two main obstacles: first, delivery barriers, including the blood–brain barrier (BBB) and deep tumor‐penetrating obstacles, hinder sufficient drug accumulation in GSCs that often reside in hypoxic niches deep in glioblastoma; second, hypoxia and the immunosuppressive tumor microenvironment (TME) limit the therapeutic responses of GSC inhibition strategies. An intercellular cell adhesion molecule 1 (ICAM‐1)‐expressing M1 macrophage‐derived small extracellular vesicles loaded with a complex of bovine serum albumin, MnO2, and the small‐molecule inhibitor PTC209 (IsEV‐BMP) is constructed to achieve sequential barrier‐breaking delivery and simultaneous TME modulation to boost GSC inhibition. ICAM‐1 facilitates endothelial transcytosis‐mediated BBB crossing, microglial transcytosis‐mediated deep tumor penetration, and internalization of IsEV‐BMPs in GSCs. Hypoxia alleviation inhibits the binding of hypoxia‐inducible factor 1α (HIF‐1α) to hypoxia‐responsive elements on the gene promoters of cancer stem cell‐related markers and CD47 in GSCs, thereby improving PTC209 sensitivity and immune phagocytosis of GSCs. IsEV‐BMP achieves simultaneous microglial polarity transition and immuno‐microenvironmental modulation during microglial transcytosis‐mediated deep tumor penetration. This study provides a strategy to overcome the sequential delivery barrier for effective glioblastoma treatment.

AbstractMagnonic devices are extensively studied for energy‐efficient information processing. High spatial resolution and high accuracy measurement is required to characterize the excitation and distribution of magnons. Here, sensing and imaging of magnons in the magnetic insulator (YIG) is realized with negatively charged boron vacancy () spin defects in 2D hexagonal boron nitride (hBN). Thermal magnon noise is studied through spin relaxometry, illustrating the nanometers proximity of the 2D quantum sensor over a large area. The small probe‐sample standoff distance helps to detect weak signals with diffraction‐limited spatial resolution. The uniform out‐of‐plane symmetry axis of is further utilized to study perpendicular magnetic anisotropy (PMA). It effectively extracts the stray field of microwave‐excited magnons from the direct stripline field. The distributions of propagating and localized magnons in different structures are subsequently imaged and analyzed. The work provides the strategy for utilizing the distinctive advantages of the van der Waals quantum sensor in magnetic imaging. The results will promote the development of magnonic devices for diverse applications.

Published: October 2024

AbstractSeparating propylene (C3H6) from propylene/propane (C3H6/C3H8) mixture using energy‐efficient adsorption is industrially important, but due to the lack of universal pore features, the rational selection of a suitable adsorbent in the ocean of porous materials is a tough task. In this study, a comprehensive work on the discovery of high‐performance C3H6/C3H8 separation adsorbents is carried out by utilizing the advantages of high‐throughput computational screening (HTCS). First, based on the HTCS data mining in the CoRE MOF 2019 and Tobacco 3.0 database, the target material, Cd‐HFDPA, is screened out. Second, the pore electrostatic potential (ESP) analysis shows that Cd‐HFDPA has obvious pore characteristics and high affinity for C3H6 according to ESP matching, which is further confirmed by adsorption isotherms, Ideal Adsorbed Solution Theory selectivity, adsorption enthalpy analyses, and breakthrough experiments. Finally, an industrial two‐bed pressure swing adsorption process for Cd‐HFDPA adsorbent is proposed and its productivity and energy consumption are compared with other benchmark materials.
Origin of Enhanced Dielectric Tunability in Antiferroelectric Ceramic Systems

Published: October 2024

AbstractAntiferroelectric ceramics are considered as highly promising materials for the development of novel DC‐link, snubber, and filter capacitors used in high‐power and high‐speed electronics for electromotive and renewable energy applications, medical equipment, and weapons platforms. In particular, the increase of the dielectric permittivity with bias electric field, i.e., the dielectric tunability, is one of the most interesting and still not fully understood properties of antiferroelectric materials. The in situ dielectric measurements and thermometry of Pb0.99Nb0.02[(Zr0.57Sn0.43)0.92Ti0.08]0.9803 ceramics reveal that the dielectric response increases with bias electric field in the antiferroelectric phase due to the non‐linear contributions, most likely originating in the irreversible domain wall motions. Furthermore, extraordinarily high values of the dielectric tunability (≈375%) and the figure of merit (≈1680%) are determined at the temperature of the triple point. The minimization of the domain size near the triple point is proposed to be responsible for the enhanced dielectric tunability. The proposed mechanism is supported by the enhanced irreversible Rayleigh coefficient and via observation of minimized domains by piezoresponse force microscopy. The exploration of the role of the domain structure in antiferroelectrics contributes to a better understanding of their unique dielectric properties and opens a new possibility for the development of high‐performance capacitors.

Published: October 2024

AbstractThe low effective capacity, inferior initial Coulombic efficiency, and unstable solid electrolyte interface (SEI) of silicon oxycarbide (SiOC) materials in lithium‐ion batteries (LIBs) pose significant challenges for the widespread application. Herein, to circumvent these issues, a micron‐sized SiOC‐based anode with 3D structure is constructed by Si and Cu co‐doping using solvent‐free ball milling for high‐performance LIBs. The Cu3Si alloy is formed in situ as an intermediate that is anchored to the surface of Si within the SiOC matrix. The unique 3D SiOC‐based anode with Cu3Si interphase provides fast electron conductivity and high mechanical strength, while facilitating the formation of a robust and LiF‐rich SEI. Specifically, the SiOC‐based anode delivers excellent cyclic stability and rate capability (750.0 mAh g−1 for 1000 cycles at 1 A g−1). Notably, the full cells equipped with an NCM811 cathode maintain this cyclic stability, achieving a 93.0% capacity retention after 150 cycles. This work provides insights into the rational fabrication of a 3D micron‐sized SiOC‐based anode with an in situ generated Cu3Si interphase for advanced LIBs and beyond.
