POINCARÉ AND SOBOLEV INEQUALITIES FOR DIFFERENTIAL FORMS IN HEISENBERG GROUPS AND CONTACT MANIFOLDS
Authors: Baldi Annalisa , Franchi Bruno , Pansu Pierre 
Published: June 2020

AbstractIn this paper, we prove contact Poincaré and Sobolev inequalities in Heisenberg groups $\mathbb{H}^{n}$, where the word ‘contact’ is meant to stress that de Rham’s exterior differential is replaced by the exterior differential of the so-called Rumin complex $(E_{0}^{\bullet },d_{c})$, which recovers the scale invariance under the group dilations associated with the stratification of the Lie algebra of $\mathbb{H}^{n}$. In addition, we construct smoothing operators for differential forms on sub-Riemannian contact manifolds with bounded geometry, which act trivially on cohomology. For instance, this allows us to replace a closed form, up to adding a controlled exact form, with a much more regular differential form.
The Shape of Emotion Regulation
Authors: Blanke Elisabeth S. , Kalokerinos Elise K. , Riediger Michaela , Brose Annette 
Published: June 2020

Abstract. The Density Distribution approach to personality characterizes traits using both mean levels and within-person variability of behaviors. Recent theory highlights that emotion regulation (ER) is inherently variable, and this Density Distribution approach seems particularly suitable to understand both average tendencies and dynamics of ER as person-specific characteristics. However, there is not yet empirical evidence for this suggestion. To fill this gap, we investigated the reliability of density distribution information gathered from repeated assessments of state ER (within-person mean levels and standard deviations). Specifically, we studied the reliability of ER strategy use in terms of internal consistency and short- and long-term stability within and across two waves of experience sampling ( N = 153, M = 70 measurement occasions). Across both average tendencies and within-person variation, we found that individuals used different ER strategies relatively consistently. Overall, within-person ER mean levels and standard deviations were stable within and across the waves. Taken together, this suggests that the person-specific overall pattern of ER use in daily life is captured reliably using experience-sampling methodology (ESM).
Seismicity on Conjugate Faults in Ölfus, South Iceland: Case Study of the 1998 Hjalli‐Ölfus Earthquake

Published: June 2020

AbstractThe Ölfus seismic belt lies at the western end of the ~E‐W sinistral transform shear zone in South Iceland, called the South Iceland Seismic Zone (SISZ), where most seismicity and surface faulting show ~N‐S dextral slip. Unlike the rest of SISZ, seismicity in west Ölfus is predominantly along the ~ENE‐WSW direction. Throughout recorded history, Ölfus has shown an interactive behavior with the Hengill volcanic system that lies northwest of the zone. For instance, the 13 November 1998 Mw 5.1 earthquake in the Hjalli area (west Ölfus) and its ~ENE trending aftershock sequence were likely triggered by the 4 June 1998 Mw 5.4 Hengill earthquake sequence. These events point to an interplay between conjugate ~N‐S and ~ENE‐WSW faults in the region. Relative relocations of earthquakes in Hjalli‐Ölfus from July 1991 to December 1999 (Icelandic Meteorological Office, 2017) are chiefly limited to 4‐ to 8‐km depth along the ~ENE direction with a few distributed on smaller ~N‐S faults. The foreshocks of the November 1998 earthquake occurred on a ~N‐S fault until a day prior to the mainshock when they shifted to the ~ENE direction. The subsequent aftershocks are also mainly restricted to the ~ENE direction. We find that the Mw 5.1 (Global Centroid Moment Tensor moment = 5.43 × 1016 N‐m) Hjalli‐Ölfus earthquake ruptured a near‐vertical ~ENE fault area of 24–40 km2 with left‐lateral average slip of 5–8 cm. Multiple relocations of the mainshock using various constraints indicate that the event likely occurred close to the junction of the conjugate ~ENE‐WSW and ~N‐S faults.
Outage Performance of Full‐Duplex Multiuser Relay Systems With Rician‐Distributed RSI
Authors: Raut Prasanna , Kumar Sharma Prabhat 
Published: June 2020

AbstractA multiuser full‐duplex (FD) two‐wayrelaying system is considered with decode‐and‐forward relaying protocol. All nodes are assumed to have FD abilities, and residual self‐interference (RSI) at each node is modeled as a Rician‐distributed random variable. Based on the availability of channel state information (CSI) at the relay node, different scheduling schemes are adopted and investigated in terms of outage probability. For the blind case when CSI is unavailable, the random scheduling is analyzed. In the presence of CSI, the absolute channel power‐based scheduling and normalized channel power‐based scheduling schemes are considered. A precise closed‐form expression for the outage probability is derived for independent and nonidentically distributed channels. The theoretical results are verified through Monte Carlo simulations.
Evolution of Brittle Structures in Plagioclase‐Rich Rocks at High‐Pressure and High‐Temperature Conditions—Linking Laboratory Results to Field Observations
Authors: Incel Sarah , Renner Jörg , Jamtveit Bjørn 
Published: June 2020

AbstractPlagioclase‐rich granulites exposed on the Lofoten archipelago, Northern Norway, display strain localization in pseudotachylytes as well as ductile shear zones that formed under similar high‐pressure and high‐temperature conditions. Pseudotachylytes or pseudotachylyte networks reveal no or very little hydration, whereas ductile shear zones reveal significant hydration. We combine these observations from the field with experimental results to characterize the structural evolution of brittle faults in plagioclase‐rich rocks at conditions of the lower continental crust. We performed a series of deformation experiments on intact granulite samples prepared from a natural granulite sample at 2.5 GPa confining pressure, a strain rate of 5 × 10−5 s−1, and temperatures of 700°C and 900°C to total strains of ~7–8% and ~33–36%. Samples were either deformed “as‐is” or with ~1 wt.% H2O added. Striking similarities between the experimental and natural microstructures suggest that the transformation of precursory brittle structures into ductile shear zones at eclogite‐facies conditions is most effective in samples deformed with added water triggering reaction and subsequent plastic deformation of the products along the faults and in the adjacent wall‐rock.

Abstract
Background
The molecular signature underlying pancreatic ductal adenocarcinoma (PDAC) progression may include key proteins affecting the malignant phenotypes. Here, we aimed to identify the proteins implicated in PDAC with different tumour-node-metastasis (TNM) stages.

Methods
Eight-plex isobaric tags coupled with two-dimensional liquid chromatography–tandem mass spectrometry were used to analyse the proteome of PDAC tissues with different TNM stages. A loss-of-function study was performed to evaluate the oncogenic roles of WD repeat-containing protein 1 (WDR1) in PDAC. The molecular mechanism by which WDR1 promotes PDAC progression was studied by real-time qPCR, Western blotting, proximity ligation assay and co-immunoprecipitation.

Results
A total of 5036 proteins were identified, and 4708 proteins were quantified with high confidence. Compared with normal pancreatic tissues, 37 proteins were changed significantly in PDAC tissues of different stages. Moreover, 64 proteins were upregulated or downregulated in a stepwise manner as the TNM stages of PDAC increased, and 10 proteins were related to tumorigenesis. The functionally uncharacterised protein, WDR1, was highly expressed in PDAC and predicted a poor prognosis. WDR1 knockdown suppressed PDAC tumour growth and metastasis in vitro and in vivo. Moreover, WDR1 knockdown repressed the activity of the Wnt/β-Catenin pathway; ectopic expression of a stabilised form of β-Catenin restored the suppressive effects of WDR1 knockdown. Mechanistically, WDR1 interacted with USP7 to prevent ubiquitination-mediated degradation of β-Catenin.

Conclusion
Our study identifies several previous functional unknown proteins implicated in the progression of PDAC, and provides new insight into the oncogenic roles of WDR1 in PDAC development.

AbstractCatalytic reductive coupling of two electrophiles and one unsaturated bond represents an economic and efficient way to construct complex skeletons, which is dominated by transition-metal catalysis via two electron transfer. Herein, we report a strategy of visible-light photoredox-catalyzed successive single electron transfer, realizing dearomative arylcarboxylation of indoles with CO2. This strategy avoids common side reactions in transition-metal catalysis, including ipso-carboxylation of aryl halides and β-hydride elimination. This visible-light photoredox catalysis shows high chemoselectivity, low loading of photocatalyst, mild reaction conditions (room temperature, 1 atm) and good functional group tolerance, providing great potential for the synthesis of valuable but difficultly accessible indoline-3-carboxylic acids. Mechanistic studies indicate that the benzylic radicals and anions might be generated as the key intermediates, thus providing a direction for reductive couplings with other electrophiles, including D2O and aldehyde.

AbstractBenthic fauna refers to all fauna that live in or on the seafloor, which researchers typically divide into size classes meiobenthos (32/64 µm–0.5/1 mm), macrobenthos (250 µm–1 cm), and megabenthos (>1 cm). Benthic fauna play important roles in bioturbation activity, mineralization of organic matter, and in marine food webs. Evaluating their role in these ecosystem functions requires knowledge of their global distribution and biomass. We therefore established the BenBioDen database, the largest open-access database for marine benthic biomass and density data compiled so far. In total, it includes 11,792 georeferenced benthic biomass and 51,559 benthic density records from 384 and 600 studies, respectively. We selected all references following the procedure for systematic reviews and meta-analyses, and report biomass records as grams of wet mass, dry mass, or ash-free dry mass, or carbon per m2 and as abundance records as individuals per m2. This database provides a point of reference for future studies on the distribution and biomass of benthic fauna.

AbstractWe analyse possibilities to quantitatively evaluate the surface second-order optical nonlinearity in noncentrosymmetric materials based on polarization-resolved analysis of far-field radiation patterns of second-harmonic generation. We analytically demonstrate that for plane-wave illumination the contribution to the second-harmonic signal from the surface of a nonlinear medium exhibits different polarization properties and angular dependencies compared to the contribution from the bulk. In view of this, we optimize the illumination geometry in order to enable the most efficient separation and comparison of both nonlinearities. Furthermore, we consider the illumination of an AlGaAs slab by a tightly-focused linearly-polarized Gaussian beam as an alternative measurement geometry. It is found that the reliable separation of the surface nonlinearity contribution as well as a wide range of detectable values can be achieved with this geometry as well.

Published: June 2020

AbstractWe aimed to evaluate the association between obesity and the incidence of retinal vein occlusion (RVO) with and without diabetes mellitus (DM).This is a retrospective cohort study using Korean National Health Insurance System data. The participants were 23,061,531 adults older than 20 years who received a health examination at least once between 2009 and 2012, and all patients were observed for RVO development until 2015. We used a multivariate adjusted Cox regression analysis to evaluate the association between RVO and body mass index (BMI) with and without DM. The analysis were evaluated via a hazard ratio (HR) and 95% confidence interval (CI). The age-, sex-, and multivariable-adjusted HRs for RVO were stratified by BMI. This population-based study revealed evidence that obesity has a different effect on the incidence of RVO in the presence and absence of DM.In people with DM, a lower BMI was associated with an increased risk of RVO, and a higher BMI was associated with a lower risk for RVO. In people without DM, the correlation was reversed: a lower BMI was associated with a lower risk for RVO and vice versa.

Published: June 2020

AbstractProtein malonylation, a reversible post-translational modification of lysine residues, is associated with various biological functions, such as cellular regulation and pathogenesis. In proteomics, to improve our understanding of the mechanisms of malonylation at the molecular level, the identification of malonylation sites via an efficient methodology is essential. However, experimental identification of malonylated substrates via mass spectrometry is time-consuming, labor-intensive, and expensive. Although numerous methods have been developed to predict malonylation sites in mammalian proteins, the computational resource for identifying plant malonylation sites is very limited. In this study, a hybrid model incorporating multiple convolutional neural networks (CNNs) with physicochemical properties, evolutionary information, and sequenced-based features was developed for identifying protein malonylation sites in mammals. For plant malonylation, multiple CNNs and random forests were integrated into a secondary modeling phase using a support vector machine. The independent testing has demonstrated that the mammalian and plant malonylation models can yield the area under the receiver operating characteristic curves (AUC) at 0.943 and 0.772, respectively. The proposed scheme has been implemented as a web-based tool, Kmalo (https://fdblab.csie.ncu.edu.tw/kmalo/home.html), which can help facilitate the functional investigation of protein malonylation on mammals and plants.

AbstractThe severe acute respiratory syndrome-coronavirus-2 (SARS-CoV-2) pandemic
affects people around the world. However, there have been striking
differences in the number of infected individuals and deaths in different
countries. Particularly, within Central Europe in countries that are similar
in ethnicity, age, and medical standards and have performed similar steps of
containment, such differences in mortality rates remain inexplicable. We
suggest to consider and explore environmental factors to explain these
intriguing variations. Countries like Northern Italy, France, Spain, and UK
have suffered from 5 times more deaths from the corona virus infection than
neighboring countries like Germany, Switzerland, Austria, and Denmark
related to the size of their respective populations. There is a striking
correlation between the level of environmental pollutants including
pesticides, dioxins, and air pollution such as NO2 known to
affect immune function and healthy metabolism with the rate of mortality in
COVID-19 pandemic in these European countries. There is also a correlation
with the use of chlorination of drinking water in these regions. In addition
to the improvement of environmental protective programs, there are
possibilities to lower the blood levels of these pollutants by therapeutic
apheresis. Furthermore, therapeutic apheresis might be an effective method
to improve metabolic inflammation, altered vascular perfusion, and
neurodegeneration observed as long-term complications of COVID-19
disease.

Superficial Circumflex Iliac Artery Perforator Flap as a Workhorse Flap: Systematic Review and Meta-analysis
Authors: Altiparmak Mehmet , Cha Han Gyu , Hong Joon P. , Suh Hyunsuk Peter 
Published: June 2020

Abstract
Background There are various advantages and disadvantages attributed to superficial circumflex iliac artery perforator (SCIP) flap. The aim of this study is to evaluate the versatility and reliability of free SCIP flap by performing a systematic review and meta-analysis of the literature in terms of flap characteristics, pedicle types, and outcomes, including the different types of flap elevations.
Methods PubMed, Embase OVID, and Cochrane CENTRAL were searched up to January 2019. All original articles and case reports published in English were included in the analysis. Anatomic descriptions, cadaveric studies, conference presentations, letter to the editors, local SCIP flaps, and review articles were excluded.
Results A total of 36 articles including 907 SCIP flaps were available for the analysis. The most frequent causes of defects were tumors (38.2%) and lower extremities were the most common recipient areas (62.7%). The average flap dimension was 73.3 ± 23.0 cm2 with a pedicle length of 5.0 ± 0.6 cm. Vessel diameter average was 0.67 ± 0.12 mm. The average number of deep branch and superficial branch used per study was 14.4 ± 8.7 (18%) and 93.3 ± 75.0 (84%), respectively. Flap failure rate and complication rate were 2.7 and 4.2%, respectively.
Conclusion SCIP flaps have been shown to be versatile in various aspects of reconstruction. The attributed disadvantages such as having short pedicle and small vessel diameter do not seem to limit the variable usage of this flap. Therefore, SCIP flap should be considered a workhorse flap.
Lexical, syntactic, and pragmatic sources of countability
Authors: Srinivasan Mahesh , Barner David 
Published: June 2020

Abstract
In this chapter, we suggest that the meanings of mass and count nouns result from the interaction of three components of language - lexical roots, syntax, and pragmatic inference. We begin by providing a brief history of early work on the mass-count distinction, and show how the experimental literature gradually converged on the idea that the mass-count distinction is rooted in quantification, rather than in the object/substance distinction. Next, we review experimental evidence suggesting that the mass-count distinction is asymmetric, such that although children and adults expect count nouns to denote individuals, they think that mass nouns can denote a wider range of phenomena including objects, substances, and actions (whether individuated or not). Based on these data, we propose a model in which count syntax takes unindividuated semantic representations as input, and specifies quantification over countable individuals, while mass syntax leaves the measuring dimension up to individual semantic representations, such that some nouns quantify according to mass/volume, while others are lexically specified for individuation and thus quantify according to number. Finally, we suggest that although syntax and lexical semantic representations help determine whether a noun denotes countable individuals, they do not specify which countable individuals they denote. Drawing on evidence from young children's surprising failures in countIng object pieces as whole objects, we propose that nouns themselves do not encode full conceptual criteria for individuation, but instead encode partial criteria that are filled out pragmatically, by contrasting alternative descriptions of objects and their parts.
Characterization of tellurium and silicon as n-type dopants for GaAsBi
Authors: Stevens Margaret A , Lenney Samuel , McElearney John , Grossklaus Kevin A , Vandervelde Thomas E 
Published: June 2020

Abstract
Films of n-GaAs1-xBix films were grown via molecular beam epitaxy using both Si and Te as dopant sources. Electron mobility was characterized by Hall effect measurements as a function of carrier concentration and Bi content for films with bismuth fractions of x = 0.02 and x = 0.06. While GaAsBi:Te shows lower majority carrier mobility than GaAsBi:Si at low Bi concentrations, the two become comparable as Bi content increases. Furthermore, it was observed that in the presence of bi-metallic Bi-Ga droplets on the film surface, films doped with Si display p-type behavior, likely due to Si preferentially occupying group-V sites. The use of Te as a dopant always resulted in n-type epilayers, making it a more reliable dopant choice for high Bi content films. Finally, ex situ annealing was studied as a method to improve majority carrier mobility in GaAs0.98Bi0.02:Te films, with a 10 min anneal at 350 °C resulting in a 30% improvement in electron mobility. Improvement of film quality was confirmed through spectroscopic ellipsometry examination of film optical properties. Annealing at higher temperatures resulted in electrical, optical, and structural degradation of the GaAsBi films.
Dissolution suppression of self-assembled GaSb quantum dots on silicon by proper surface preparation

Published: June 2020

Abstract
The temperature stability of high-density GaSb quantum dots grown on a Si(111) surface using solid-phase epitaxy is investigated during annealing at 450 °C. It is found that the bare silicon surface plays a critical role in the GaSb decomposition through the destruction of Sb–Ga bonds with the simultaneous formation of Sb–Si bonds. GaSb decomposition can be significantly suppressed if saturated monolayer coverage in the form of the Si(111)-(√3 × √3)-R30°-Sb surface reconstruction is preliminarily formed. This allows GaSb quantum dots to be embedded in the silicon matrix using molecular beam epitaxy at high temperature.
