Abstract. The Arctic Snow Microstructure Experiment (ASMEx) took place in Sodankylä, Finland in the winters of 2013–2014 and 2014–2015. Radiometric, macro-, and microstructure measurements were made under different experimental conditions of homogenous snow slabs, extracted from the natural seasonal taiga snowpack. Traditional and modern measurement techniques were used for snow macro- and microstructure observations. Radiometric measurements of the microwave emission of snow on reflector and absorber bases were made at frequencies 18.7, 21.0, 36.5, 89.0, and 150.0 GHz, for both horizontal and vertical polarizations. Two measurement configurations were used for radiometric measurements: a reflecting surface and an absorbing base beneath the snow slabs. Simulations of brightness temperatures using two microwave emission models, the Helsinki University of Technology (HUT) snow emission model and Microwave Emission Model of Layered Snowpacks (MEMLS), were compared to observed brightness temperatures. RMSE and bias were calculated; with the RMSE and bias values being smallest upon an absorbing base at vertical polarization. Simulations overestimated the brightness temperatures on absorbing base cases at horizontal polarization. With the other experimental conditions, the biases were small, with the exception of the HUT model 36.5 GHz simulation, which produced an underestimation for the reflector base cases. This experiment provides a solid framework for future research on the extinction of microwave radiation inside snow.
Global-scale modelling of melting and isotopic evolution of Earth's mantle: melting modules for TERRA

Published: April 2016

Abstract. Many outstanding problems in solid-Earth science relate to the geodynamical explanation of geochemical observations. Currently, extensive geochemical databases of surface observations exist, but satisfying explanations of underlying mantle processes are lacking. One way to address these problems is through numerical modelling of mantle convection while tracking chemical information throughout the convective mantle. We have implemented a new way to track both bulk compositions and concentrations of trace elements in a finite-element mantle convection code. Our approach is to track bulk compositions and trace element abundances via particles. One value on each particle represents bulk composition and can be interpreted as the basalt component. In our model, chemical fractionation of bulk composition and trace elements happens at self-consistent, evolving melting zones. Melting is defined via a composition-dependent solidus, such that the amount of melt generated depends on pressure, temperature and bulk composition of each particle. A novel aspect is that we do not move particles that undergo melting; instead we transfer the chemical information carried by the particle to other particles. Molten material is instantaneously transported to the surface layer, thereby increasing the basalt component carried by the particles close to the surface and decreasing the basalt component in the residue. The model is set to explore a number of radiogenic isotopic systems, but as an example here the trace elements we choose to follow are the Pb isotopes and their radioactive parents. For these calculations we will show (1) the evolution of the distribution of bulk compositions over time, showing the buildup of oceanic crust (via melting-induced chemical separation in bulk composition), i.e. a basalt-rich layer at the surface, and the transportation of these chemical heterogeneities through the deep mantle; (2) the amount of melt generated over time; (3) the evolution of the concentrations and abundances of different isotopes of the trace elements (U, Th, K and Pb) throughout the mantle; and (4) a comparison to a semi-analytical theory relating observed arrays of correlated Pb isotope compositions to melting age distributions (Rudge, 2006).

Abstract
Double-wavelength intersubband electroluminescence at ∼7 and ∼10 µm was obtained using a simple five-well quantum cascade structure. Electron injection from a common injector level to two neighboring emitting wells was realized by resonant tunneling or phonon-assisted tunneling, determined by the energy separation between the injector level E
0 and the upper-emitting levels under various bias electric fields. Such simple quantum cascade structures might lead to a new solution for dual-color mid-infrared lasers.

Published: April 2016

ABSTRACTRecently, an effective hemostatic dressing requirement has become a major problem in both the military and civilian world. Available hemostatic agents are too expensive, ineffective, unsafe, or complicated to use. Here, we evaluated the hemostatic efficacy of a nano/micro bilayer hemostatic dressing including a porous sublayer from chitosan (CTS) and bacterial cellulose (BC) and a nanofibrillar upper layer from silk fibroin (SF). In addition, several active agents rolled in coagulation cascade [vitamin K (Vit K), protamine sulfate (PS), kaolin (Kao), etc.] were doped to the sublayer of bilayer hemostatic agent and their activities were compared via in vivo and in vitro tests. Lactate dehydrogenase (LDH) activity test results demonstrated that BC/CTS, SF‐coated BC/CTS, and Vit K K/BC/CTS, SF/phosphatidylcholine (PC)‐coated BC/CTS showed higher LDH activity compared to standard gauze (p < 0.005). In a femoral artery bleeding rat model, SF‐coated PS/BC/CTS significantly reduced bleeding time (80 ± 0.3 s) compared to standard gauze and kaolin‐doped group (p < 0.005). Blood loss and mortality rate with 2.3 g and 37.5% SF‐coated BC/CTS and SF‐coated PS/BC/CTS showed increased efficacy in achieving hemostasis compared to standard gauze. All the prepared hemostatic dressings except for kaolin‐doped BC/CTS and standard gauze induced no inflammatory reaction in the tissue. All these data suggest that active agent‐doped BC/CTS/SF‐based bilayer hemostatic dressings have a great influence on the resulting hemostatic action. © 2016 Wiley Periodicals, Inc. J. Appl. Polym.

Published: April 2016

ABSTRACTThe development of flexible, thin‐film, and high‐efficiency III–V solar cells enables the design of new flexible, lightweight solar arrays for space applications. A requirement for these solar panels is the replacement of the rigid coverglasses by a flexible shielding layer. In this work, three candidate materials based on commercially available polyimides and synthesized polysiloxanes for such a shielding layer are compared with respect to their ease of synthesis, transparency. Polysiloxanes based on methyltrimethoxysilane (MTMS) based siloxane (MBS) showed the best reproducibility in synthesis of layers of the required thickness of about 300 µm with sufficient transparency and was therefore selected for further analysis. It was demonstrated that the MBS material could be doped with Ce to increase the radiation hardness. Showing virtually no loss of volatile condensable components in outgassing tests it can be concluded that the properties MBS are found suitable for further space qualification testing. © 2016 Wiley Periodicals, Inc.

Published: April 2016

ABSTRACTThis article provides a detailed investigation of crystallization behavior and morphology of polylactic acid (PLA) in the presence of a nucleating agent: potassium salt of 5‐dimethyl sulfoisothalate, an aromatic sulfonate derivative (Lak‐301). Isothermal crystallization kinetics of PLA melt mixed with Lak at concentrations of 0.25–1 wt % was investigated at a range of crystallization temperature, 140–150 °C. To gain further insight on the effect of Lak, nonisothermal differential scanning calorimetry (DSC), wide angle X‐ray diffraction (WAXD), polarized optical microscope (POM), heat deflection temperature (HDT), and rheology were also performed. At 0.25 wt % Lak, crystallinity of PLA increased from 10% to 45%, and in 1 wt % Lak, maximum crystallinity of 50% was achieved. With 1 wt % Lak, crystallization half time reduced to 1.8 min from 61 min for neat PLA at 140 °C. The isothermal crystallization kinetics was analyzed using Avrami model. Values of the Avrami exponent for PLA with Lak were mainly in the range of 3 indicating a three dimensional crystal growth is favored. Crystallization rate was found to increase with increase in Lak content. Observation from POM confirmed that the presence of Lak in the PLA matrix significantly increased the nucleation density. © 2016 Wiley Periodicals, Inc. J. Appl. Polym. Sci. 2016, 133, 43673.

To explore the possibility of isosteric replacement of imidazolidinone moiety of (S)‐1‐(1‐(4‐aminobenzoyl)indolin‐5‐ylsulfonyl)‐4‐phenylimidazolidin‐2‐one (1) for the anticancer activity, novel 1‐(1‐acyl substituted indolin‐5‐sulfonyl)‐4‐phenyl‐1H‐imidazoles 2 were prepared with varying the N‐acyl group on the indoline ring and evaluated for their in vitro anticancer activity against six human cancer cell lines (renal ACHN, colon HCT‐15, breast MDA‐MB‐231, lung NCI‐H23, stomach NUGC‐3, and prostrate PC‐3). Among the analogs prepared, imidazoles with hydrophobic acyl substituents on indoline like cyclohexanecarbonyl (2e, mean 50% growth inhibition [GI50
] = 2.29 μM) or benzoyl with electron‐donating groups like 4‐methoxybenzoyl (2g, mean GI50
= 4.11 μM) and 4‐aminobenzoyl (2a, mean GI50
= 4.45 μM) exhibited relatively good cytotoxicity. Although imidazole moiety of arylsulfonylphenylimidazole 2 contains only hydrogen bonding acceptor property without a stereogenic center unlike imidazolidinone analogs, the high level of the activity of 2 proved that the imidazole motif is obviously good isostere of imidazolidinone moiety of arylsulfonylphenylimidazolidinone 1 for the anticancer activity.

AbstractPreclinical studies suggest that ALK‐1 signaling mediates a complementary angiogenesis pathway activated upon development of resistance to vascular endothelial growth factor (VEGF)‐targeted therapies. Inhibition of ALK‐1 signaling may lead to disruption of tumor angiogenesis and growth. We report findings from a multicenter, open‐label, phase I study of the fully human anti‐ALK‐1 mAb PF‐03446962 conducted in Japan and South Korea, in Asian patients with advanced solid tumors. The dose escalation Part 1 of the study was based on a standard 3 + 3 design (n = 16). In Part 2, patients were treated with PF‐03446962 at 7 and 10 mg/kg (10/cohort), including patients with disease progression following prior VEGF receptor (R)‐targeted therapy. Primary objectives were determination of the maximum tolerated dose (MTD) and recommended phase II dose (RP2D). Secondary objectives included safety, pharmacokinetics, pharmacodynamics, and antitumor activity of PF‐03446962. No dose‐limiting toxicity (DLT) was noted in the 12 DLT‐evaluable patients. Treatment was well tolerated. The MTD for biweekly intravenous administration was estimated to be 10 mg/kg and the RP2D 7 mg/kg. Treatment‐related grades 1–3 thrombocytopenia was experienced by 27.8% patients. The most frequent nonhematologic treatment‐related AEs were grades 1–2 pyrexia and epistaxis. Four patients (3/4 with hepatocellular carcinoma) developed telangiectasia suggesting vascular targeting and in vivo ALK‐1 inhibition by PF‐03446962. Stable disease for 12 weeks or more was observed in 25.7% of patients and in 44.4% of those with hepatocellular carcinoma. ALK‐1 inhibition by PF‐03446962 may represent a novel antiangiogenic strategy for patients with advanced solid malignancies complementary to current treatment with VEGF(R)‐targeted inhibitors or chemotherapy.
Moving survivorship care plans forward: focus on care coordination
Authors: Salz Talya , Baxi Shrujal 
Published: April 2016

AbstractAfter completing treatment for cancer, the coordination of oncology and primary care presents a challenge for cancer survivors. Many survivors need continued oncology follow‐up, and all survivors require primary care. Coordinating the shared care of a cancer survivor, or facilitating an informed handoff from oncology to primary care, is essential for cancer survivors. Survivorship care plans are personalized documents that summarize cancer treatment and outline a plan of recommended ongoing care, with the goal of facilitating the coordination of post‐treatment care. Despite their face validity, five trials have failed to demonstrate the effectiveness of survivorship care plans. We posit that these existing trials have critical shortcomings and do not adequately address whether survivorship care plans improve care coordination. Moving forward, we propose four criteria for future trials of survivorship care plans: focusing on high‐needs survivor populations, tailoring the survivorship care plan to the care setting, facilitating implementation of the survivorship care plan in clinical practice, and selecting appropriate trial outcomes to assess care coordination. When trials meet these criteria, we can finally assess whether survivorship care plans help cancer survivors receive optimal oncology and primary care.

AbstractNative chemical ligation combined with desulfurization has become a powerful strategy for the chemical synthesis of proteins. Here we describe the use of a new thiol additive, methyl thioglycolate, to accomplish one‐pot native chemical ligation and metal‐free desulfurization for chemical protein synthesis. This one‐pot strategy was used to prepare ubiquitin from two or three peptide segments. Circular dichroism spectroscopy and racemic protein X‐ray crystallography confirmed the correct folding of ubiquitin. Our results demonstrate that proteins synthesized chemically by streamlined 9‐fluorenylmethoxycarbonyl (Fmoc) solid‐phase peptide synthesis coupled with a one‐pot ligation–desulfurization strategy can supply useful molecules with sufficient purity for crystallographic studies.
