AutoSpec: Fast Automated Spectral Extraction Software for IFU Data Cubes
Authors: Griffiths Alex , Conselice Christopher J. 
Published: December 2018

Abstract
With the ever-growing popularity of integral field unit (IFU) spectroscopy, countless observations are being performed over multiple object systems such as blank fields and galaxy clusters. With this, an increasing amount of time is being spent extracting one-dimensional object spectra from large three-dimensional data cubes. However, a great deal of information available within these data cubes is overlooked in favor of photometrically based spatial information. Here we present a novel yet simple approach of optimal source identification utilizing the wealth of information available within an IFU data cube, rather than relying on ancillary imaging. Through the application of these techniques, we show that we are able to obtain object spectra comparable to deep photometry-weighted extractions without the need for ancillary imaging. Further, implementing our custom-designed algorithms can improve the signal-to-noise ratio of extracted spectra and successfully deblend sources from nearby contaminants. This will be a critical tool for future IFU observations of blank and deep fields, especially over large areas where automation is necessary. We implement these techniques in the Python-based spectral extraction software, AutoSpec, which is available via GitHub at https://github.com/a-griffiths/AutoSpec and Zenodo at https://doi.org/10.5281/zenodo.1305848.
Des minorités pas comme les autres ?

Resume Nés du système esclavagiste et de la colonisation avant de devenir des territoires français à part entière, les départements d’outremer sont aussi reliés à la France métropolitaine par d’importants flux migratoires. À partir du module de l’enquête « Trajectoires et Origines » portant sur le vécu du racisme et des discriminations et de 33 entretiens menés avec des migrants ultramarins, cette étude fait ressortir l’expérience commune aux migrants des DOM et aux immigrés postcoloniaux, en particulier ceux issus d’Afrique subsaharienne. Comme ces derniers, les ultramarins reportent de nombreux traitements inégalitaires liés à leur couleur de peau, tout en mobilisant des stratégies de mise à distance. Parmi ces stratégies, les registres de différenciation vis-à-vis de certains groupes migratoires occupent une place importante. Les ultramarins écartent le stigmate du racisme en insistant sur la distance les séparant des autres non-blancs. Leurs récits reflètent ainsi la dualité du racisme, entre relégation des migrants dans une même altérité et mise en concurrence de ces populations.

Authors: Blanco-Canqui Humberto , Ruis Sabrina J. , Speth Carol A. , Lee Donald J. 
Published: December 2018

Core Ideas
Undergraduate students favored field activities related to soil management to enhance their learning.
Most students indicated that field tests connected lecture with reality.
Field activities can improve learning of soil management, particularly for non‐soils major students.
Pairing lectures with field activities can be an effective strategy to teach large (>75) undergraduate soil courses with a wide variety of majors.
Enhancing student learning of soil management demands effective teaching strategies. Devoting some lecture periods to field activities could provide a hands‐on learning experience, but studies on this approach—particularly in lecture‐only, diverse‐major, and large undergraduate courses—are not available. We assessed this approach for 3 years in a soil management course for a total of 211 undergraduate students with diverse but related majors. About 23 to 37% of the students were non‐soils or non‐agronomy majors each year. We included two field sessions in fall semester of each year to illustrate how management affects soil processes and properties. Student surveys (21 questions), using ratings on a scale of 1 (strongly disagree) to 5 (strongly agree), showed that students favored field practicals (>4). Students perceived that the written report regarding the field activities further aided their learning (mean of 3.25 across 3 years). Field tests connected lectures with real‐world application, especially for non‐soils/agronomy majors. Some challenges with lecture–field activity teaching approach for large classes (>75 students) include providing opportunities for each student to conduct field measurements, limited time during field tests, and compromising lecture material coverage with in‐depth learning material, among others. Overall, connecting lectures with field activities can improve student perception of increased learning of soil management, particularly for non‐soils major students.
Beowulf Cluster Computing with Windows
Authors: Sterling Thomas 
Published: December 2018

Comprehensive guides to the latest Beowulf tools and methodologies.
Beowulf clusters, which exploit mass-market PC hardware and software in conjunction with cost-effective commercial network technology, are becoming the platform for many scientific, engineering, and commercial applications. With growing popularity has come growing complexity. Addressing that complexity, Beowulf Cluster Computing with Linux and Beowulf Cluster Computing with Windows provide system users and administrators with the tools they need to run the most advanced Beowulf clusters. The book is appearing in both Linux and Windows versions in order to reach the entire PC cluster community, which is divided into two distinct camps according to the node operating system. Each book consists of three stand-alone parts. The first provides an introduction to the underlying hardware technology, assembly, and configuration. The second part offers a detailed presentation of the major parallel programming librairies. The third, and largest, part describes software infrastructures and tools for managing cluster resources. This includes some of the most popular of the software packages available for distributed task scheduling, as well as tools for monitoring and administering system resources and user accounts. Approximately 75% of the material in the two books is shared, with the other 25% pertaining to the specific operating system. Most of the chapters include text specific to the operating system. The Linux volume includes a discussion of parallel file systems.
The sterol-responsive RNF145 E3 ubiquitin ligase mediates the degradation of HMG-CoA reductase together with gp78 and Hrd1

Published: December 2018

Mammalian HMG-CoA reductase (HMGCR), the rate-limiting enzyme of the cholesterol biosynthetic pathway and the therapeutic target of statins, is post-transcriptionally regulated by sterol-accelerated degradation. Under cholesterol-replete conditions, HMGCR is ubiquitinated and degraded, but the identity of the E3 ubiquitin ligase(s) responsible for mammalian HMGCR turnover remains controversial. Using systematic, unbiased CRISPR/Cas9 genome-wide screens with a sterol-sensitive endogenous HMGCR reporter, we comprehensively map the E3 ligase landscape required for sterol-accelerated HMGCR degradation. We find that RNF145 and gp78 independently co-ordinate HMGCR ubiquitination and degradation. RNF145, a sterol-responsive ER-resident E3 ligase, is unstable but accumulates following sterol depletion. Sterol addition triggers RNF145 recruitment to HMGCR via Insigs, promoting HMGCR ubiquitination and proteasome-mediated degradation. In the absence of both RNF145 and gp78, Hrd1, a third UBE2G2-dependent E3 ligase, partially regulates HMGCR activity. Our findings reveal a critical role for the sterol-responsive RNF145 in HMGCR regulation and elucidate the complexity of sterol-accelerated HMGCR degradation.Editorial note: This article has been through an editorial process in which the authors decide how to respond to the issues raised during peer review.

Published: December 2018

AbstractA 17‐month‐old boy from Vancouver, Canada, presented with a 5‐day history of progressive somnolence, ataxia, and torticollis. Additional investigations revealed eosinophilic encephalitis with deep white matter changes on MR imaging. On day 13, serology came back positive for Baylisascaris procyonis antibodies. While prophylaxis after ingestion of soil or materials potentially contaminated with raccoon feces can prevent baylisascariasis, timely treatment can sometimes alter a disastrous outcome. Populations of infected raccoons are propagating globally, but cases of Baylisascaris neural larva migrans have so far only been reported from North America.

AbstractHighly ordered pattern formation of block copolymers (BCPs) within nanoscale templates is of great interest for generating diverse ordered nanostructures. Here, introduced is a combined methodology of nanotransfer printing (nTP) and BCP self‐assembly to guide the formation of spherical nanodots within a printed crossbar nanotemplate. By successfully accommodating poly(styrene‐b‐dimethylsiloxane) (PS‐b‐PDMS) BCPs in the guiding metallic crossbar nanotemplate (≈30 × 30 nm2), a well‐organized array of single‐domain PDMS spheres (≈10 nm) with a square symmetry is successfully obtained in an extremely short annealing time (<5 s). The self‐consistent field theory simulation results theoretically explain the spontaneous one‐to‐one accommodation of PDMS spheres in the confined area of the crossbar template. This approach can potentially be extended to the many other BCP materials and morphologies to diversify the geometry of self‐assembled BCP and/or transfer‐printed nanopatterns for various types of nanodevice applications.
Discrete‐Continuum Duality of Architected Materials: Failure, Flaws, and Fracture

Published: December 2018

Abstract3D nano‐ and micro‐architected materials are resilient under compression; their susceptibility to flaws and fracture remain unexplored. This work reports the fabrication and tensile‐to‐failure response of hollow alumina nanolattices arranged into 5 µm octet‐truss unit cells. Some specimens contained through‐thickness center notches oriented at different angles to the loading direction, with a length‐over‐sample‐width ratio of 0.45. In situ tensile experiments reveal that for all orientations, failure initiates at the notch root, followed by instantaneous crack propagation along lattice planes orthogonal to extension. A tensile strength of 27.4 ± 0.7 MPa is highest for unnotched samples and decreases as notch orientation varies from 0° to 90° to its minimum, 7.2 ± 0.4 MPa; their specific tensile strength is ≈4 × higher than that for all other low‐density materials. Finite element simulations reproduce observed strengths and failure mechanisms: initial cracks always initiate at the nodal junctions with highest stress concentrations by tearing of alumina walls at the nodes. Subsequent crack propagation shifts maximum stress concentration to the nodes along lattice plane orthogonal to the loading direction. A modified analytical fracture model based on the effective notch length predicts tensile strengths consistent with experiments. These findings imply that continuum fracture mechanics can predict failure in nano‐architected materials, which helps develop advanced materials through informed architectural design.

Published: December 2018

AbstractStability and scalability have become the two main challenges for perovskite solar cells (PSCs) with the research focus in the field advancing toward commercialization. One of the prerequisites to solve these challenges is to develop a cost‐effective, uniform, and high quality electron transport layer that is compatible with stable PSCs. Sputtering deposition is widely employed for large area deposition of high quality thin films in the industry. Here the composition, structure, and electronic properties of room temperature sputtered SnO2 are systematically studied. Ar and O2 are used as the sputtering and reactive gas, respectively, and it is found that a highly oxidizing environment is essential for the formation of high quality SnO2 films. With the optimized structure, SnO2 films with high quality have been prepared. It is demonstrated that PSCs based on the sputtered SnO2 electron transport layer show an efficiency up to 20.2% (stabilized power output of 19.8%) and a T80 operational lifetime of 625 h. Furthermore, the uniform and thin sputtered SnO2 film with high conductivity is promising for large area solar modules, which show efficiencies over 12% with an aperture area of 22.8 cm2 fabricated on 5 × 5 cm2 substrates (geometry fill factor = 91%), and a T80 operational lifetime of 515 h.

Published: December 2018

AbstractMyocardial infarction (MI), caused by coronary heart disease (CHD), remains one of the most common causes of death in the United States. Over the last few decades, scientists have invested considerable resources on the study and development of cell therapies for myocardial regeneration after MI. However, due to a number of limitations, they are not yet readily available for clinical applications. Mounting evidence supports the theory that paracrine products are the main contributors to the regenerative effects attributed to these cell therapies. The next generation of cell‐based MI therapies will identify and isolate cell products and derivatives, integrate them with biocompatible materials and technologies, and use them for the regeneration of damaged myocardial tissue. This review discusses the progress made thus far in pursuit of this new generation of cell therapies. Their fundamental regenerative mechanisms, their potential to combine with other therapeutic products, and their role in shaping new clinical approaches for heart tissue engineering, are addressed.

Published: December 2018

AbstractPhotonic elastomers that can change colors like a chameleon have shown great promise in various applications. However, it still remains a challenge to produce artificial photonic elastomers with desired optical and mechanical properties. Here, the generation of metallosupramolecular polymer‐based photonic elastomers with tunable mechanical strength, angle‐independent structural color, and self‐healing capability is reported. The photonic elastomers are prepared by incorporating isotropically arranged monodispersed SiO2 nanoparticles within a supramolecular elastomeric matrix based on metal coordination interaction between amino‐terminated poly(dimethylsiloxane) and cerium trichloride. The photonic elastomers exhibit angle‐independent structural colors, while Young's modulus and elongation at break of the as‐formed photonic elastomers reach 0.24 MPa and 150%, respectively. The superior elasticity of photonic elastomers enables their chameleon‐skin‐like mechanochromic capability. Moreover, the photonic elastomers are capable of healing scratches or cuts to ensure sustainable optical and mechanical properties, which is crucial to their applications in wearable devices, optical coating, and visualized force sensing.
Genetically Induced In Situ‐Poling for Piezo‐Active Biohybrid Nanowires

Published: December 2018

AbstractPolycrystalline piezo‐active materials only exhibit a high macroscopic piezoresponse if they consist of particles with oriented crystal directions and aligned intrinsic dipole moments. For ferroelectric materials, the postsynthesis alignment of the dipoles is generally achieved by electric poling procedures. However, there are numerous technically interesting non‐ferroelectric piezo‐active materials like zinc oxide (ZnO). These materials demand the alignment of their intrinsic dipoles during the fabrication process. Therefore, in situ‐poling techniques have to be developed. This study utilizes genetically modified M13 phage templates for the generation of force fields, which directly control the ZnO dipole poling. By genetic modification of M13 phage template, the piezoelectric response of the ZnO/M13 phage hybrid nanowire is doubled compared to the hybrid nanowire based on unmodified M13 wild type (wt) phage templates. Thus, the formation of piezo‐active domains consisting of oriented ZnO nanocrystals is directly induced by the genetic modification. By the combination of the fiber‐like structure of individual M13 phages with the bioenhanced electromechanical properties of ZnO, hybrid nanowires with a length of ≈1.1 µm and a thickness of ≈63.5 nm are fabricated with a high piezoelectric coefficient of up to d33 = 7.8 pm V−1 for genetically modified M13 phage templates.
Fabrication of Metal–Organic Framework Thin Films Using Programmed Layer‐by‐Layer Assembly Techniques
Authors: Wang Zhengbang , Wöll Christof 
Published: December 2018

AbstractMetal–organic frameworks (MOFs) are a rather new class of crystalline, nanoporous solids that are self‐assembled from inorganic, metal or metal‐oxo nodes and organic linkers. Powder MOFs are originally developed for gas storage and catalyst applications, but more recently, more advanced applications have used well‐defined MOF thin films in electronic, photonic, and sensing devices. MOF thin films for targeted applications can be fabricated on appropriately functionalized substrates using a programmed layer‐by‐layer (LbL) assembly technique, which yields oriented, highly crystalline MOF thin films (surface‐mounted MOFs, SURMOFs). The LbL assembly technique as well as the huge potential of SURMOFs is presented herein. Emerging SURMOF properties related to their heteroepitaxy, postsynthetic modification/crosslinking, lithography, and photoswitching are highlighted.

AbstractLong‐term implantation of biomedical electronics into the human body enables advanced diagnostic and therapeutic functionalities. However, most long‐term resident electronics devices require invasive procedures for implantation as well as a specialized receiver for communication. Here, a gastric resident electronic (GRE) system that leverages the anatomical space offered by the gastric environment to enable residence of an orally delivered platform of such devices within the human body is presented. The GRE is capable of directly interfacing with portable consumer personal electronics through Bluetooth, a widely adopted wireless protocol. In contrast to the passive day‐long gastric residence achieved with prior ingestible electronics, advancement in multimaterial prototyping enables the GRE to reside in the hostile gastric environment for a maximum of 36 d and maintain ≈15 d of wireless electronics communications as evidenced by the studies in a porcine model. Indeed, the synergistic integration of reconfigurable gastric‐residence structure, drug release modules, and wireless electronics could ultimately enable the next‐generation remote diagnostic and automated therapeutic strategies.
Self‐Regulating Capabilities in Photonic Robotics

Published: December 2018

AbstractTraditional robots are machines programmed to accomplish tasks, thanks to a complex ensemble of sensors connected to a computer “brain” which elaborate signals to drive specific actions. This complex network suffers from limitations—the need for a central computer, for instance, poses a limit to device miniaturization and requires a large amount of energy. A promising development, made possible by recent advances in material science, endeavors a new generation of soft robots that are multifunctional, compliant, and autonomous in ways that are similar to biological organisms. In particular, photoresponsive polymers are demonstrated to be valid candidates to substitute the computer‐based intelligence with an “intrinsic” material cleverness. First demonstrations of self‐sustained motions as oscillations or autonomous walking are described. In these cases, light also provides a solution to a second, very important, issue in microrobotics, which is the availability of a source of energy. Light actuation together with smart polymers can be combined into self‐controlled robots capable of simple decision‐making processes, for example with robotic grippers that are able to distinguish particles with different colors. In addition, the most recent examples about the integration of a form of robotic “intelligence” into a single material with a minimal level of consciousness are reported.

Published: December 2018

AbstractFlexible wearable sensors are expected to be the future generation of personal health monitoring devices with large‐area, multimodal, multipoint sensing, and complicated data analysis. However, multimaterial interfacial coalescence and mechanical matching critically challenge the advancement of flexible devices and multifunction integration. Graphene, with characteristic carbon sheet 2D material, is endowed with good transparency, stability, superior electron mobility, heat conductivity, excellent flexibility, and mechanical performance. A summary of the progresses of flexible graphene‐based sensors in terms of material processing, sensor configuration, and property is presented. Various assembly structures could perform different electrical behaviors with unitary graphene material. The diversity of graphene‐based temperature, humidity, pressure, strain, and integrated multifunctional sensors developed in recent years is detailed. Benefitting from the commendable flexible mechanical performance and high durability, flexible graphene‐based sensors promote practical applications in body temperature monitoring, voice recognition, pulse‐beating, motion, and respiration detection. Finally, future research following the development trends and challenges of integrated graphene‐based sensors to develop their potential in human health monitoring and human–machine interfaces are discussed.
