Spectral attenuation of ocean waves in pack ice and its application in calibrating viscoelastic wave-in-ice models
Authors: Cheng Sukun , Stopa Justin , Ardhuin Fabrice , Shen Hayley H. 
Published: June 2020

Abstract. We investigate a case of ocean waves through a pack ice
cover captured by Sentinel-1A synthetic aperture radar (SAR) on 12 October 2015 in the Beaufort Sea. The study domain is 400 km by 300 km, adjacent to a
marginal ice zone (MIZ). The wave spectra in this domain were reported in a
previous study (Stopa et al., 2018b). In that study, the authors divided the
domain into two regions delineated by the first appearance of leads (FAL)
and reported a clear change of wave attenuation of the total energy between
the two regions. In the present study, we use the same dataset to study the
spectral attenuation in the domain. According to the quality of SAR-retrieved wave spectrum, we focus on a range of wave numbers corresponding to
9–15 s waves from the open-water dispersion relation. We
first determine the apparent attenuation rates of each wave number by pairing
the wave spectra from different locations. These attenuation rates slightly
increase with increasing wave number before the FAL and become lower and more
uniform against wave number in thicker ice after the FAL. The spectral
attenuation due to the ice effect is then extracted from the measured
apparent attenuation and used to calibrate two viscoelastic wave-in-ice
models. For the Wang and Shen (2010b) model, the calibrated equivalent shear
modulus and viscosity of the pack ice are roughly 1 order of magnitude
greater than that in grease and pancake ice reported in Cheng et al. (2017).
These parameters obtained for the extended Fox and Squire model are much
greater, as found in Mosig et al. (2015) using data from the Antarctic MIZ.
This study shows a promising way of using remote-sensing data with large
spatial coverage to conduct model calibration for various types of ice
cover.Highlights. Three key points:
The spatial distribution of wave number and spectral attenuation in pack ice
are analyzed from SAR-retrieved surface wave spectra. The spectral attenuation rate of 9–15 s waves varies around
10−5 m2 s−1, with lower values in thicker semicontinuous ice fields
with leads. The calibrated viscoelastic parameters are greater than those found in
pancake ice.

Poging middels voorwaardelijk opzet
Welke rol speelt de aanmerkelijke kans bij de vraag of er sprake is van een strafbare poging? De auteurs betogen dat voor de beantwoording van de vraag of een kans aanmerkelijk is aansluiting moet worden gezocht bij het perspectief van de objectieve derde die, direct voorafgaand aan het moment van handelen, meekijkt over de schouder van de dader en die alleen die feiten en omstandigheden kent die de dader kent. Bepalend is of deze objectieve, in de schoenen van de dader staande, derde op basis van die kennis zou oordelen dat de mogelijkheid dat het voorziene gevolg zal intreden reëel en niet onwaarschijnlijk is.

Responsivt forældresamarbejde i skolen
Authors: Lund Gro Emmertsen 
Published: June 2020

Responsivt forældresamarbejde handler om skolens måde at møde og samarbejde med elevernes forældre på. For skolens professionelle er forældresamarbejdet en del af kerneopgaven. Undersøgelser viser dog, at samarbejdet ofte opleves svært og krævende, hvilket kan have store negative konsekvenser for de implicerede, ikke mindst familierne. Responsivt forældresamarbejde tager afsæt i de professionelles ansvar og kompetencer og lægger fokus på de forholdemåder og handlinger, hvormed de professionelle indgår i og faciliterer samarbejdsprocesser med forældrene. Artiklen redegør for, hvad responsivt forældresamarbejde betyder, og hvordan det kan se ud i praksis. Artiklen viser, hvordan de dominerende diskurser om forældresamarbejde stiller sig hindrende i vejen for et responsivt forældresamarbejde. Hermed argumenteres for et behov for en ny diskurs, som artiklen forsøger at give et bud på.
Ocean warming is the key filter for successful colonization of the migrant octocoral Melithaea erythraea (Ehrenberg, 1834) in the Eastern Mediterranean Sea

Climate, which sets broad limits for migrating species, is considered a key filter to species migration between contrasting marine environments. The Southeast Mediterranean Sea (SEMS) is one of the regions where ocean temperatures are rising the fastest under recent climate change. Also, it is the most vulnerable marine region to species introductions. Here, we explore the factors which enabled the colonization of the endemic Red Sea octocoral Melithaea erythraea (Ehrenberg, 1834) along the SEMS coast, using sclerite oxygen and carbon stable isotope composition (δ18OSC and δ13CSC), morphology, and crystallography. The unique conditions presented by the SEMS include a greater temperature range (∼15 °C) and ultra-oligotrophy, and these are reflected by the lower δ13CSCvalues. This is indicative of a larger metabolic carbon intake during calcification, as well as an increase in crystal size, a decrease of octocoral wart density and thickness of the migrating octocoral sclerites compared to the Red Sea samples. This suggests increased stress conditions, affecting sclerite deposition of the SEMS migrating octocoral. The δ18Osc range of the migrating M. erythraea indicates a preference for warm water sclerite deposition, similar to the native depositional temperature range of 21–28 °C. These findings are associated with the observed increase of minimum temperatures in winter for this region, at a rate of 0.35 ± 0.27 °C decade−1 over the last 30 years, and thus the region is becoming more hospitable to the Indo-Pacific M. erythraea. This study shows a clear case study of “tropicalization” of the Mediterranean Sea due to recent warming.
The benefits of smoking cessation on survival in cancer patients by integrative analysis of multi‐omics data

Published: June 2020

Few studies have examined the association between smoking status (including former smokers) at diagnosis and overall survival among cancer patients. We aimed to assess the benefits of quitting smoking on cancer prognosis in cohorts of cancer patient smokers obtained from the Cancer Genome Atlas (TCGA) database. Hazard ratios (HR) were calculated to evaluate smoking behavior at cancer diagnosis (reformed smokers vs. current smokers) in association with overall survival using multivariate‐adjusted Cox regressions analysis. According to our analyses, quitting smoking was the independent protective factor for overall survival in lung squamous cell carcinoma (LUSC) (HR = 0.67, 95% CI = 0.48–0.94). Comprehensive analysis of multicomponent data across reformed and current smokers identified a total of 85 differential expressed genes (DEGs) affected by different modes of genetic and epigenetic regulation, potentially representing cancer drivers in smokers. Moreover, we provided a smoking‐associated gene expression signature, which could evaluate the true effect on prognosis with high power (HR = 1.70, 95% CI = 1.19–2.43, AUC = 0.65, 0.67, and 0.70 for 2‐, 3‐, and 5‐year survival, respectively). This signature was also applicable in other smoking‐related cancers, including bladder urothelial carcinoma (HR = 1.70, 95% CI = 1.01–2.88), cervical carcinoma (HR = 5.69, 95% CI = 1.37–23.69), head and neck squamous cell carcinoma (HR = 1.97, 95% CI = 1.41–2.76), lung adenocarcinoma (HR = 1.73, 95% CI = 1.16–2.57), and pancreatic adenocarcinoma (HR = 4.28, 95% CI = 1.47–12.47). In conclusion, this study demonstrates that quitting smoking at diagnosis decreases risk of death in cancer patients. We also provide a smoking‐associated gene expression signature to evaluate the effect of smoking on survival. Lastly, we suggest that smoking cessation could comprise a part of cancer treatment to improve survival rates of cancer patients.

AbstractMany applications of 2D materials require deposition of non‐2D metals and metal‐oxides onto the 2D materials. Little is however known about the mechanisms of such non‐2D/2D interfacing, particularly at the atomic scale. Here, atomically resolved scanning transmission electron microscopy (STEM) is used to follow the entire physical vapor deposition (PVD) cycle of application‐relevant non‐2D In/In2O3 nanostructures on graphene. First, a “quasi‐in‐situ” approach with indium being in situ evaporated onto graphene in oxygen‐/water‐free ultra‐high‐vacuum (UHV) is employed, followed by STEM imaging without vacuum break and then repeated controlled ambient air exposures and reloading into STEM. This allows stepwise monitoring of the oxidation of specific In particles toward In2O3 on graphene. This is then compared with conventional, scalable ex situ In PVD onto graphene in high vacuum (HV) with significant residual oxygen/water traces. The data shows that the process pathway difference of oxygen/water feeding between UHV/ambient and HV fabrication drastically impacts not only non‐2D In/In2O3 phase evolution but also In2O3/graphene out‐of‐plane texture and in‐plane rotational van‐der‐Waals epitaxy. Since non‐2D/2D heterostructures' properties are intimately linked to their structure and since influences like oxygen/water traces are often hard to control in scalable fabrication, this is a key finding for non‐2D/2D integration process design.

AbstractForces and relative movement between cells and extracellular matrix (ECM) are crucial to the self‐organization of tissues during development. However, the spatial range over which these dynamics can be controlled in engineering approaches is limited, impeding progress toward the construction of large, structurally mature tissues. Herein, shape‐morphing materials called “kinomorphs” that rationally control the shape and size of multicellular networks are described. Kinomorphs are sheets of ECM that change their shape, size, and density depending on patterns of cell contractility within them. It is shown that these changes can manipulate structure‐forming behaviors of epithelial cells in many spatial locations at once. Kinomorphs are built using a new photolithographic technology to pattern single cells into ECM sheets that are >10× larger than previously described. These patterns are designed to partially mimic the branch geometry of the embryonic kidney epithelial network. Origami‐inspired simulations are then used to predict changes in kinomorph shapes. Last, kinomorph dynamics are shown to provide a centimeter‐scale program that sets specific spatial locations in which ≈50 µm‐diameter epithelial tubules form by cell coalescence and structural maturation. The kinomorphs may significantly advance organ‐scale tissue construction by extending the spatial range of cell self‐organization in emerging model systems such as organoids.

Published: June 2020

AbstractA flexible and conformal thin film proximity sensor array based on organic semiconductor dinaphtho[2,3‐b:2′,3′‐f]thieno[3,2‐b]thiophene (DNTT) is demonstrated, which can be perfectly affixed onto the curved objects such as glass ball, human brain model, and even the deforming human skin. Both spatial position and shape can be registered with fast response when human finger or insulator plastic to be recognized is approaching and removing. This flexible, conformal organic semiconductor sensor array bears merits of low operation voltage (1 V) and ultralow power consumption (0.36 nW), which is ideal for applications of the electronic skin in future wearable electronics.

Published: June 2020

AbstractAn integrated electrochromic–hybrid supercapacitor (EHSC) is demonstrated; the device’s operation (charging–discharging) is indicated by optical changes (from colored to transparent). The heart of the device is an electrochromic metallo–organic layer that functions as both the battery‐type electrode and the charge indicator. The capacitive electrode is a layered composite of multiwalled carbon nanotubes (MWCNTs) and a conductive polymer (poly(3,4‐ethylenedioxythiophene) polystyrene sulfonate, PEDOT:PSS). The device operates under low potentials (−0.6 to 2 V), displays high energy and power densities (≈2.2 Wh kg−1 and ≈2529 W kg−1), a high coulomb efficiency (99%), a short charging time (≈2 s), and a charge retention (V½) of ≈60 min. Stability, both in color and energy, for more than 1000 consecutive charging–discharging cycles is demonstrated. No significant changes in device temperature are indicated under the operating conditions. The EHSC is wired with a conventional circuit board to be charged and subsequently to operate a diode. The results demonstrate the potential of metallo–organic assemblies for usage in these types of supercapacitors.

Published: June 2020

AbstractIntravaginal rings (IVRs) represent a sustained‐release approach to drug delivery and have long been used and investigated for hormones and microbicides delivery. For decades, IVRs have been manufactured by injection molding and hot‐melt extrusion with very limited design and material capabilities. Additive manufacturing (AM), specifically digital light synthesis (DLS), represents an opportunity to harness the freedom of design to expand control and tunability of drug release properties from IVRs. A novel approach to IVR design and manufacturing is reported that results in geometrically complex internal architectures through the incorporation of distinct unit cells using computationally aided design (CAD) software. A systematic approach is developed to design through the generation of an IVR library and the effects of these parameters are investigated on ring properties. The ability to precisely and predictably control the compressive properties of the IVR independent of the internal architecture with which control of drug release kinetics can be achieved is demonstrated, thus opening the door for a “plug‐and‐play” platform approach to IVR fabrication.

AbstractIn this paper, a transmission‐type graphene plasmonic modulator by introducing off‐resonant Au structure is theoretically and experimentally investigated. It is found that the modulation efficiency and bandwidth could be dramatically enhanced compared with bare graphene plasmonic structure. The validity of this proposed method is verified both in the 1D and 2D graphene plasmonic structures: ribbons and holes. This work will open up a new path to design the high‐efficiency modulators, switches, and multispectral detectors.

AbstractIridium‐catalyzed enantioselective transfer hydrogenation of ketones with formic acid was developed using a prolinol‐phosphine chiral ligand. Cooperative action of the iridium atom and the ligand through alcohol‐alkoxide interconversion is crucial to facilitate the transfer hydrogenation. Various ketones including alkyl aryl ketones, ketoesters, and an aryl heteroaryl ketone were competent substrates. An attractive feature of this catalysis is efficient discrimination between the alkyl and aryl substituents of the ketones, promoting hydrogenation with the identical sense of enantioselection regardless of steric demand of the alkyl substituent and thus resulting in a rare case of highly enantioselective transfer hydrogenation of tert‐alkyl aryl ketones. Quantum chemical calculations revealed that the sp3‐C−H/π interaction between an sp3‐C−H bond of the prolinol‐phosphine ligand and the aryl substituent of the ketone is crucial for the enantioselection in combination with O−H⋅⋅⋅O/sp3‐C−H⋅⋅⋅O two‐point hydrogen‐bonding between the chiral ligand and carbonyl group.magnified image

AbstractBiodegradable metallic materials represent a potential step‐change technology that may revolutionize the treatment of broken bones. Implants made with biodegradable metals are significantly stronger than their polymer counterparts and fully biodegradable in vivo, removing the need for secondary surgery or long‐term complications. Here, it is shown how clinically approved Mg alloy promotes improved bone repair using an integrated state of the art fetal mouse metatarsal assay coupled with in vivo preclinical studies, second harmonic generation, secretome array analysis, perfusion bioreactor, and high‐resolution 3D confocal imaging of vasculature within skeletal tissue, to reveal a vascular‐mediated pro‐osteogenic mechanism controlling enhanced tissue regeneration. The optimized mechanical properties and corrosion rate of the Mg alloy lead to a controlled release of metallic Mg, Ca, and Zn ions at a rate that facilitates both angiogenesis and coupled osteogenesis for better bone healing, without causing adverse effects at the implantation site. The findings from this study support ongoing development and refinement of biodegradable metal systems to act as crucial portal technologies with significant potential to improve many clinical applications.

Published: June 2020

AbstractAs a typical class of single‐atom catalysts (SACs) possessing prominent advantages of high reactivity, high selectivity, high stability, and maximized atomic utilization, emerging metal‐nitrogen‐doped carbon (M‐N‐C) materials, wherein dispersive metal atoms are coordinated to nitrogen atoms doped in carbon nanomaterials, have presented a high promise to replace the conventional metal or metal oxides‐based catalysts. In this work, recent progress in M‐N‐C‐based materials achieved in both theoretical and experimental investigations is summarized and general principles for novel catalysts design from electronic structure modulating are provided. Firstly, the applications and mechanisms on the advantages and challenges of M‐N‐C‐based materials for a variety of sustainable fuel generation and bioinspired reactions, including the oxygen reduction reaction (ORR), oxygen evolution reaction (OER), hydrogen evolution reaction (HER), carbon dioxide reduction reaction (CO2RR), nitrogen reduction reaction (NRR), and nanozyme reactions are reviewed. Then, strategies toward enhancing the catalytic performance by engineering the nature of metal ion centers, coordinative environment of active centers, carbon support, and their synergistic cooperation, are proposed. Finally, prospects for the rational design of next generation high‐performance M‐N‐C‐based catalysts are outlined. It is expected that this work will provide insights into high‐performance catalysts innovation for sustainable and environmental technologies.
