Abstract
We present a timing analysis of the eclipsing post-common envelope binary (PCEB) DE CVn. Based on new CCD photometric observations and published data, we found that the orbital period in DE CVn has a cyclic period oscillation with an amplitude of 28.08 s and a period of 11.22 years plus a rapid period decrease at a rate of

. According to the evolutionary theory, secular period decreases in PCEBs arise from angular momentum losses (AMLs) driven by gravitational radiation (GR) and magnetic braking (MB). However, the observed orbital decay is too fast to be produced by AMLs via GR and MB, indicating that there could be another AML mechanism. We suggest that a circumbinary disk around DE CVn may be responsible for the additional AML. The disk mass was derived as a few ×10−4–10−3
M
⊙ , which is in agreement with that inferred from previous studies in the order of magnitude. The cyclic change is most likely the result of the gravitational perturbation by a circumbinary object due to the Applegate’s mechanism failing to explain such a large period oscillation. The mass of the potential third body is calculated as

. Supposing the circumbinary companion and the eclipsing binary are coplanar, its mass would correspond to a giant planet. This hypothetical giant planet is moving in a circular orbit of a radius of ∼5.75(±2.02) au around its host star.
The Association of Filaments, Polarity Inversion Lines, and Coronal Hole Properties with the Sunspot Cycle: An Analysis of the McIntosh Database

Published: November 2018

Abstract
Filaments and coronal holes, two principal features observed in the solar corona, are sources of space weather variations. Filament formation is closely associated with polarity inversion lines (PILs) on the solar photosphere which separate positive and negative polarities of the surface magnetic field. The origin of coronal holes is governed by large-scale unipolar magnetic patches on the photosphere from where open magnetic field lines extend to the heliosphere. We study the properties of filaments, PILs, and coronal holes in solar cycles 20, 21, 22, and 23 utilizing the McIntosh archive. We detect a prominent cyclic behavior of filament length, PIL length, and coronal hole area with significant correspondence with the solar magnetic cycle. The spatio-temporal evolution of the geometric centers of filaments shows a butterfly-like structure and distinguishable poleward migration of long filaments during cycle maxima. We identify this rush to the poles of filaments to be co-temporal with the initiation of polar field reversal as gleaned from Mount Wilson and Wilcox Solar Observatory polar field observations, and quantitatively establish their temporal correspondence. We analyze the filament tilt angle distribution to constrain their possible origins. The majority of the filaments exhibit negative and positive tilt angles in the northern and the southern hemispheres, respectively, strongly suggesting that their formation is governed by the overall large-scale magnetic field distribution on the solar photosphere and not by the small-scale intra-active region magnetic field configurations. We also investigate the hemispheric asymmetry in filaments, PILs, and coronal holes. We find that the hemispheric asymmetry in filaments and PILs is positively correlated with sunspot area asymmetry, whereas coronal hole asymmetry is uncorrelated.
The Role of Gravity in Producing Power-law Mass Functions

Abstract
Numerical simulations of star formation have found that a power-law mass function can develop at high masses. In a previous paper, we employed isothermal simulations that created large numbers of sinks over a large range in masses to show that the power-law exponent of the mass function,

, asymptotically and accurately approaches Γ = −1. Simple analytic models show that such a power law can develop if the mass accretion rate

In this paper, we show that the expected accretion rate dependence is more closely realized provided the gravitating mass is taken to be the sum of the sink mass and the mass in the near environment. This reconciles the observed mass functions with the accretion rate dependencies, and demonstrates that power-law upper mass functions are essentially the result of gravitational focusing, a mechanism present in, for example, the competitive accretion model.

Abstract
Uncontrolled inflammatory response during sepsis predominantly contributes to the development of multiorgan failure and lethality. However, the cellular and molecular mechanisms for excessive production and release of proinflammatory cytokines are not clearly defined. In this study, we show the crucial role of the GTPase Ras-related protein in brain (Rab)1a in regulating the nucleotide binding domain-like receptor family, pyrin domain containing 3 (NLRP3) inflammasome activation and lung inflammatory injury. Expression of dominant negative Rab1 N124I plasmid in bone marrow–derived macrophages prevented the release of IL-1β and IL-18, NLRP3 inflammasome activation, production of pro–IL-1β and pro–IL-18, and attenuated TLR4 surface expression and NF-кB activation induced by bacterial LPS and ATP compared with control cells. In alveolar macrophage–depleted mice challenged with cecal ligation and puncture, pulmonary transplantation of Rab1a-inactivated macrophages by expression of Rab1 N124I plasmid dramatically reduced the release of IL-1β and IL-18, neutrophil count in bronchoalveolar lavage fluid, and inflammatory lung injury. Rab1a activity was elevated in alveolar macrophages from septic patients and positively associated with severity of sepsis and respiratory dysfunction. Thus, inhibition of Rab1a activity in macrophages resulting in the suppression of NLRP3 inflammasome activation may be a promising target for the treatment of patients with sepsis.
Mesospheric bores at southern midlatitudes observed by ISS-IMAP/VISI: a first report of an undulating wave front
Authors: Hozumi Yuta , Saito Akinori , Sakanoi Takeshi , Yamazaki Atsushi , Hosokawa Keisuke 
Published: November 2018

Abstract. Large-scale spatial structures of mesospheric bores were observed by the
Visible and near-Infrared Spectral Imager (VISI) of the ISS-IMAP mission
(Ionosphere, Mesosphere, upper Atmosphere and Plasmasphere mapping mission
from the International Space Station) in the mesospheric O2 airglow
at 762 nm wavelength. Two mesospheric bore events in southern midlatitudes
are reported in this paper: one event at 48–54∘ S,
10–20∘ E on 9 July 2015 and the other event at 35–43∘ S,
24∘ W–1∘ E on 7 May 2013. For the first event, the
temporal evolution of the mesospheric bore was investigated from the
difference of two observations in consecutive passes. The estimated eastward
speed of the bore is 100 m s−1. The number of trailing waves increased
with a rate of 3.5 waves h−1. Anticlockwise rotation with a speed of
20∘ h−1 was also recognized. These parameters are similar to
those reported by previous studies based on ground-based measurements, and
the similarity supports the validity of VISI observation for mesospheric
bores. For the second event, VISI captured a mesospheric bore with a
large-scale and undulating wave front. The horizontal extent of the wave
front was 2200 km. The long wave front undulated with a wavelength of
1000 km. The undulating wave front is a new feature of mesospheric bores
revealed by the wide field of view of VISI. We suggest that nonuniform bore
propagating speed due to inhomogeneous background ducting structure might be
a cause of the undulation of the wave front. Temperature measurements from
the Sounding of the Atmosphere using Broadband Emission Radiometry (SABER)
onboard the Thermosphere, Ionosphere, Mesosphere, Energetics and Dynamics
(TIMED) satellite indicated that bores of both events were ducted in a
temperature inversion layer.

Abstract. Although Arctic marine ecosystems are changing rapidly,
year-round monitoring is currently very limited and presents multiple
challenges unique to this region. The Chukchi Ecosystem Observatory (CEO)
described here uses new sensor technologies to meet needs for continuous,
high-resolution, and year-round observations across all levels of the
ecosystem in the biologically productive and seasonally ice-covered Chukchi
Sea off the northwest coast of Alaska. This mooring array records a broad
suite of variables that facilitate observations, yielding better
understanding of physical, chemical, and biological couplings, phenologies,
and the overall state of this Arctic shelf marine ecosystem. While cold
temperatures and 8 months of sea ice cover present challenging conditions for
the operation of the CEO, this extreme environment also serves as a rigorous
test bed for innovative ecosystem monitoring strategies. Here, we present
data from the 2015–2016 CEO deployments that provide new perspectives on the
seasonal evolution of sea ice, water column structure, and physical
properties, annual cycles in nitrate, dissolved oxygen, phytoplankton blooms,
and export, zooplankton abundance and vertical migration, the occurrence of
Arctic cod, and vocalizations of marine mammals such as bearded seals. These
integrated ecosystem observations are being combined with ship-based
observations and modeling to produce a time series that documents biological
community responses to changing seasonal sea ice and water temperatures while
establishing a scientific basis for ecosystem management.
Modelling the fate of surface melt on the Larsen C Ice Shelf
Authors: Buzzard Sammie , Feltham Daniel , Flocco Daniela 
Published: November 2018

Abstract. Surface melt lakes lower the albedo of ice shelves, leading to additional
surface melting. This can substantially alter the surface energy balance and
internal temperature and density profiles of the ice shelf. Evidence suggests
that melt lakes also played a pivotal role in the sudden collapse of the
Larsen B Ice Shelf in 2002. Here a recently developed, high-physical-fidelity model accounting for the
development cycle of melt lakes is applied to the Larsen C Ice Shelf,
Antarctica's most northern ice shelf and one where melt lakes have been
observed. We simulate current conditions on the ice shelf using weather
station and reanalysis data and investigate the impacts of potential future
increases in precipitation and air temperature on melt lake formation, for
which
concurrent increases lead to an increase in lake depth. Finally, we assess the viability in future crevasse propagation through the
ice shelf due to surface meltwater accumulation.
What historical landfast ice observations tell us about projected ice conditions in Arctic archipelagoes and marginal seas under anthropogenic forcing
Authors: Laliberté Frédéric , Howell Stephen E. L. , Lemieux Jean-François , Dupont Frédéric , Lei Ji 
Published: November 2018

Abstract. Arctic landfast ice extent and duration are examined from observations, ice assimilations,
ocean reanalyses and coupled models. From observations and
assimilations, it is shown that in areas where landfast ice conditions last
more than 5 months the first-year ice typically grows to more than 2 m and is
rarely less than 1 m. The observed spatial distribution of landfast ice
closely matches assimilation products but less so for ocean reanalyses and
coupled models. Although models generally struggle to represent the landfast
ice necessary to emulate the observed import/export of sea ice in regions
favourable to landfast ice conditions, some do exhibit both a realistic
climatology and a realistic decline of landfast ice extent under an
anthropogenic forcing scenario. In these more realistic simulations,
projections show that an extensive landfast ice cover should remain for at
least 5 months of the year, well into the end of the 21st century. This is in
stark contrast with the simulations that have an unrealistic emulation of
landfast ice conditions. In these simulations, slow and packed ice conditions
shrink markedly over the same period. In all simulations and in areas with
landfast ice that lasts more than 5 months, the end-of-winter sea ice thickness
remains between 1 and 2 m, well beyond the second half of the century. It is
concluded that in the current generation of climate models, projections of
winter sea ice conditions in the Canadian Arctic Archipelago and the Laptev
Sea are overly sensitive to the representation of landfast ice conditions and
that ongoing development in landfast ice parameterization will likely better
constrain these projections.
Application of a paste-type acellular dermal matrix for coverage of chronic ulcerative wounds
Authors: Jeon Minseok , Kim So Young 
Published: November 2018

Background Chronic wounds occur due to failure of the normal healing process, associated with a lack of deposition of cellular components and a suitable microenvironment such as the extracellular matrix (ECM). Acellular dermal matrix (ADM) is viewed as an ECM substitute, and a paste-type ADM has recently been introduced. We hypothesized that CGPaste, an injectable paste-type ADM, could serve as a scaffold and promote wound healing.
Methods We retrospectively studied seven patients in whom CGPaste was applied between 2017 and 2018, who had pressure ulcers, necrotizing fasciitis, diabetic foot ulcers, traumatic defects, and osteomyelitis. The goal of applying CGPaste was to achieve complete wound healing with re-epithelialization or growth of granulation tissue, depending upon the wound bed status. CGPaste was injected based on the wound size along with the application of a dressing.
Results Four of the seven patients showed granulation tissue on their wound bed, while the other three patients had a bony wound bed. The mean wound area was 453.57 mm2 and the depth was 10.71 mm. Wound healing occurred in five of the seven patients (71.43%). The mean duration of complete healing was 2.4 weeks. Two patients showed failure due to paste absorption (29.57%); these patients had wound beds comprising bone with relatively large and deep wounds (40×30 and 30×20 mm2 in area and 15 and 10 mm in depth).
Conclusions CGPaste is an effective option for coverage of small and deep chronic wounds for which a flap operation or skin grafting is unfeasible.

Bio‐Tribology and Bio‐Lubrication of Plant Cell Walls
Authors: Dolan Grace K. , Yakubov Gleb E. , Stokes Jason R. 
Published: November 2018

Abstract
This article considers the underpinning role of interactive forces at the cell wall and cellulose–fibre interfaces in the physiological and biophysical functionality of the various non‐cellulosic components that are present within the plant cell walls. We specifically introduce the use of tribological science (friction and lubrication) to obtain new insights into relative movements occurring between cells and between cellulose fibrils within the cell walls, and the potential influence on friction forces by pectin, hemicelluloses, and expansins. This approach may provide a basis for describing physical phenomena which define the system's behaviour during growth, morphogenesis, and mechanical deformation of plants.

Published: November 2018

AbstractA strategy of materials synthesis, characteristic evaluations, and manufacturing process for a mechanically elastic, biologically safe silicon‐based dopamine detector that is designed to be completely transient, i.e., dissolved in water and/or biofluids, potentially in the brain after a desired period of operation, is introduced. Use of inexpensive, bioresorbable iron (Fe)‐based nanoparticles (NPs) is one of the attractive choices for efficient catalytic oxidation of dopamine as an alternative for noble, nontransient platinum (Pt) nanoparticles, based on extensive studies of synthesized materials and catalytic reactions. Arrays of transient dopamine sensors validate electrochemical functionality to determine physiological levels of dopamine and to selectively sense dopamine in a variety of neurotransmitters, illuminating feasibilities for a higher level of soft, transient electronic implants integrated with other components of overall system.
High‐Performance PE‐BN/PVDF‐HFP Bilayer Separator for Lithium‐Ion Batteries

Published: November 2018

AbstractHighly efficient and thermally stable polyethylene‐hexagonal boron nitride/poly(vinylidene fluoride‐hexafluoropropylene) (PE‐BN/PVDF‐HFP) bilayer separator with microporous structure is prepared, for the first time with a wet chemistry method. The incorporation of hexagonal boron nitride particles in PE matrix promotes the interfacial interaction between PE and PVDF‐HFP layers to prevent separation of layers and supresses dendrite growth owing to the strong adsorption energy with polymers, large interactive surface area, and superior mechanical capability. The PVDF‐HFP layer provides additional thermally stable backbone while its inherent hydrophilic property and highly porous structure improve the overall performance of the separator. The bilayer separator owns a high electrolyte uptake of 348% and a thermal shrinkage of 6.6% upon annealing at 140 °C for 1 h. The lithium iron phosphate/lithium cell with the as‐prepared separator owns a high ionic conductivity up to 4.4 × 10−4 S cm−1, and a room‐temperature capacity of 120 mAh g−1 at 2 C with a 95% capacity retention after 500 cycles and a capability of 108 mAh g−1 at 4 C. The PE‐BN/PVDF‐HFP separator is a promising alternative of traditional multilayer separators for high‐performance lithium‐ion batteries.
