Published: November 2019

Obesity and diabetes increase hypertensive disorders of pregnancy (HDP) risk, thus preventive interventions are heavily studied. How pregestational prediabetes and related interventions impact HDP risk is less characterized. Therefore, we searched and reviewed the literature to assess the impact on HDP risk of prediabetes and varied interventions. We identified 297 citations related to pregnancy, prediabetes, and early pregnancy interventions. We also reviewed the references and citations of included articles. We included five studies assessing HDP outcomes in women with first trimester hemoglobin A1c in the prediabetes range (5.7–6.4%). One prospective observational study demonstrated first trimester hemoglobin A1c (5.9–6.4%) is associated with increased HDP risk, while another prospective observational study and one retrospective observational study had similar trends without statistical significance. A small and underpowered randomized controlled trial demonstrated initiating gestational diabetes mellitus treatment (i.e., diet, monitoring, ± insulin) in response to first trimester hemoglobin A1c (5.7–6.4%) did not statistically reduce HDP compared with standard care. One retrospective observational study suggested metformin, when started early, may reduce HDP risk in patients with prediabetes. Pregestational prediabetes appears to increase HDP risk. Interventions (i.e., metformin, diet/glucose monitoring, and/or exercise) to reduce HDP risk require additional study with long-term follow-up.

Published: November 2019

Introduction CO2 pneumoperitoneum can influence the biological behavior of neuroblastoma (NB). Angiogenesis and genetic features are responsible for malignant phenotype of this tumor. We examined the CO2 effects on N-Myc, vascular endothelial growth factor (VEGF), and matrix metalloproteinase-2 (MMP-2) expression as critical biomarkers of tumor invasiveness, in NB cells without N-Myc amplification.

Materials and Methods SH-SY5Y cells were exposed to CO2 (100%) at 15 mm Hg pressure for 4 hours and then moved to normal condition for 24 hours. Control cells were incubated with 5% CO2 for the same time. In control and CO2-exposed cells, the messenger ribonucleic acid (mRNA) levels of hypoxia-inducible factor (HIF)-1α, HIF-2α, VEGF-A, and MMP-2 were quantified by real-time polymerase chain reaction. N-Myc expression was evaluated by Western blot analysis.

Results The exposure to 15 mm Hg CO2 (100%) for 4 hours induced an increase in HIF-1α, but not in HIF-2α, mRNA levels. No differences were observed in N-Myc expression between exposed and control cells at each incubation time. Similarly, no significant differences were found for VEGF-A and MMP-2 transcript levels. In CO2 exposed cells, we observed only a slight increase in both VEGF-A and MMP-2 mRNA levels after 4 and 24 hours in comparison to controls.

Conclusion In our study, the hypoxic environment induced by CO2 exposure does not affect the expression of critical biomarkers of NB aggressiveness, such as N-Myc, VEGF, and MMP-2, in human SH-SY5Y NB cells without N-Myc amplification. These data suggest that CO2 pneumoperitoneum might not adversely impact NB cell invasiveness; however, it is necessary to evaluate these effects in others in vitro and in vivo models.
Failure to Thrive, Jaundice, and Polyuria in Early Infancy: Common Presentation with an Uncommon Lethal Etiology
Authors: Sharma Sonia
Published: November 2019

A 5-month-old female infant from a consanguineous Indian Muslim family presented with polyuria, polydipsia, failure to thrive, impaired renal function, and neonatal hepatitis of unknown cause at 1 month of age. Clinical exome testing revealed renal–hepatic–pancreatic dysplasia caused by homozygous c. 1985 + 5G > A pathogenic variations in NPHP3. Our case illustrates delay in confirmatory diagnosis of such rare disorders in our region due to the lack of suspicion and unawareness of the availability of genetic testing even when there are no cost constraints.

Affective urbanism: towards inclusive design praxis
Authors: Viderman Tihomir , Knierbein Sabine
Published: November 2019

This paper conceptualizes affective urbanism as both research framework and praxis, engaging professionals and concerned publics alike in the insurgent making of cities. With its focus on affect and bodily encounters, it taps into the rich knowledge of practices of improvising and inventing in everyday life, which tend to fall outside the realm of discursive and visual representations. An analysis of spatial practices of the collectivePlataforma de Afectados Por La Hipotecain Barcelona illustrates how a mobilization of affects fosters not only individual, but first and foremost a collective capacity to negotiate belonging, appropriate space and contest alienated conditions of everyday life. The argument rests on the hypothesis that affect implicates the ethical engagement with people at places of everyday life, thus producing a medium and means for transgressing socio-spatial divides and challenging practices of exclusion, othering and dispossession. The value of this kind of work does not necessarily lie in the quality of conceived or materialized design, but rather in enacting an inclusive and empathic design praxis which connects to people’s multiple lived spaces and cultivates lived space of deep and caring social relations.

Authors: Kim Jeong-Ah , Shin Dong-Uy
Published: November 2019

Motivated by the zigzag strip bundles which are combinatorial models realizing the crystals B(∞) for the quantum affine algebras Uq(g), where g=Bn(1),Dn(1),Dn+1(2),Cn(1), A2n−1(2),A2n(2), we introduce a new combinatorial model called strip bundles for the quantum affine algebra Uq(G2(1)). We give new realizations S(∞) and S(λ) of the crystal B(∞) and the highest weight crystals B(λ) over Uq(G2(1)) using strip bundles, and as subsets of S(∞) and S(λ), we also give realizations of the crystal B(∞) and the highest weight crystals B(λ) over the quantum finite algebra Uq(G2). Moreover, we give characterizations of the image of the crystal embedding Ψi and the connected component C1 in the set M of all Nakajima monomials which are isomorphic to the crystal B(∞) over Uq(G2(1)).
Evidence of trap-assisted Auger recombination in low radiative efficiency MBE-grown III-nitride LEDs
Authors: Espenlaub Andrew C. , Myers Daniel J. , Young Erin C. , Marcinkevičius Saulius , Weisbuch Claude , Speck James S.
Published: November 2019

By studying low radiative efficiency blue III-nitride light emitting diodes (LEDs), we find that the ABC model of recombination commonly used for understanding efficiency behavior in LEDs is insufficient and that additional effects should be taken into account. We propose a modification to the standard recombination model by incorporating a bimolecular nonradiative term. The modified model is shown to be in much better agreement with the radiative efficiency data and to be more consistent than the conventional model with very short carrier lifetimes measured by time-resolved photoluminescence in similar, low radiative efficiency material. We present experimental evidence that a hot carrier-generating process is occurring within these devices, in the form of measurements of forward photocurrent under forward bias. The forward photocurrent, due to hot carrier generation in the active region, is present despite the lack of any “efficiency droop”—the usual signature of band-to-band Auger recombination in high-quality III-nitride LEDs. Hot carrier generation in the absence of band-to-band Auger recombination implies that some other source of hot carriers exists within these low radiative efficiency devices, such as trap-assisted Auger recombination.
Morphological design of complex oxides during pulsed-laser deposition: The role of plasma-plume expansion

Published: November 2019

Complex oxides such as tin-doped indium oxide (ITO) are widely utilized as transparent conductors in a variety of functional devices. Typically, they are fabricated by sputtering, which often requires additional annealing to achieve high transparency and conductivity. Using pulsed laser deposition (PLD), both high transparency and high conductivity have been achieved without annealing, using instead selected gas species and pressures. However, the relative roles of Stranski-Krastanov-like and vapor-liquid-solid (VLS) growth modes during morphological transitions remain controversial. Here, we report on PLD of ITO in an inert-gas environment, identifying the role of plasma-plume expansion in the selection of VLS vs vapor-solid (VS) growth. For the lowest N2 pressure, indium-tin droplet formation, followed by self-catalyzed VLS growth, is observed. With increasing N2 pressure, a transition from VLS to VS growth is apparent. It is hypothesized that oxygen scattering at the lowest N2 pressure induces a metal-rich plume, which leads to metal droplet formation, followed by VLS growth. As the N2 pressure is increased, the plasma-plume and its metal-rich core are compressed, resulting in a transition to VS growth. This tunable compression of the plasma-plume offers a route to the morphological design of a wide range of functional complex oxide devices with tunable optical and electronic performance.
Eulerian conditional statistics of turbulent flow in a macroscale multi-inlet vortex chemical reactor
Authors: Hitimana Emmanuel , Fox Rodney O. , Hill James C. , Olsen Michael G.
Published: November 2019

The conditional velocity time averages (⟨Ui|ξ⟩) and conditional mixture fraction time averages (⟨Φ|ωi⟩) were computed based on the Eulerian approach from the experimental data measured in a macroscale multi-inlet vortex chemical reactor. The conditioning events were determined by equally sized intervals of the sample space variable for the mixture fraction (ξ) and the velocity vector (ωi). The experimental data, which consisted of instantaneous velocities and concentration fields for two Reynolds numbers (Re = 3250 and 8125), were acquired using the simultaneous stereoscopic particle image velocimetry (stereo-PIV) and planar laser induced fluorescence techniques. Two mathematical models, the linear approximation and probability density function (PDF) gradient diffusion, were validated by experimental results. The results of the velocity conditioned on the mixture fraction demonstrated that the linear model works well in a low turbulence region away from the reactor center. Near the reactor center, high velocity gradients coupled with low concentration gradients reduce the accuracy of the linear model predictions. Nevertheless, an excellent agreement was found for the conditional events within ±2Φrms (mixture fraction root mean square). Due to lower concentration gradient in the tangential direction, the linear model better predicted the tangential velocity component for all locations investigated. The PDF model with an isotropic turbulent diffusivity performed inadequately for the tangential and axial velocity components. A modified version of the PDF model that considers the three components of the turbulent diffusivity produced a better agreement with the experimental data especially in the spiral arms regions of significant concentration gradients. Furthermore, the mixture fraction conditioned on the velocity vector components showed a more linear behavior near the reactor center, where the PDF of the mixture fraction is a Gaussian distribution. As the concentration gradients became prominent away from the reactor, ⟨Φ|ωi⟩ also deviated from the linear pattern. This was especially remarkable for the mixture fraction conditioned on the tangential velocity. The overall prediction of ⟨Φ|ωi⟩ improves at higher Reynolds number as the fluid mixing is enhanced.

Published: November 2019

We present a simple method to measure the degrees of circular polarization (DoCP) of laser light inside a vacuum chamber and the birefringence of a vacuum window by detecting the fluorescence emitted by Doppler cooled ions in an ion trap. Imperfect laser polarization will cause ions to be pumped to the dark state which will decrease the fluorescence rates of the ions. With a simulation based on the rate equations of the relevant energy levels of 25Mg+ ions, we find that the fluorescence rate is sensitive to the DoCP of the laser. Based on the simulation result, we present a new method to optimize the DoCP of the laser inside the vacuum chamber by adjusting fast axis azimuthal angles of a half-wave plate and a quarter-wave plate outside the vacuum chamber. The laser light is optimized to be circularly polarized with an uncertainty of the DoCP of 7.8 × 10−5. With the obtained polarization information on both sides of the vacuum window and treating the vacuum window as an unknown wave plate, the phase delay and the fast axis azimuthal angle of the vacuum window can be determined in the form of Mueller matrix. The phase delay is determined to be 197.60(39)°, and the fast axis azimuthal angle is determined to be 104.00(5)°.
Activation volume details from nonlinear anelastic deformation of a metallic glass
Authors: Lei T. J. , Atzmon M.
Published: November 2019

At high stress, the viscosity of a metallic glass is non-Newtonian, and therefore the rate of anelastic stress relaxation is not linear in the applied stress. In this regime, one can obtain information on the details of the activation volume that are not accessible in the linear regime. While bending in the nonlinear regime introduces a complicated stress state, it offers great stability for noninstrumented measurements over many orders of magnitude of time. We have developed a method of controlled sample bending to a strain of up to ∼0.0155 for Al86.8Ni3.7Y9.5 metallic glass. Significant nonlinearity of the anelastic strain in the stress was observed, which is mainly associated with the largest and slowest shear transformation zones involved not reaching mechanical equilibrium at the end of the constraining period. Combining nonlinear kinetics under constraint and zero bending moment after constraint removal, the volume of the largest shear transformation zones and the transformation shear strain were obtained independently for the inherent state—their most likely values are 4.8 × 10−28 m3 and 0.18, respectively.
Spontaneous super-radiative cascade undulator emission from short dense electron bunches
Authors: Bandurkin I. V. , Oparina Yu. S. , Osharin I. V. , Savilov A. V.
Published: November 2019

We propose to use super-radiative self-compression of a short dense electron bunch to provide the cascade two-undulator regime of spontaneous emission from the bunch. At the first stage of this cascade, the spontaneous super-radiative emission of a relatively long-wavelength wave results in compression of the bunch by the radiated field. This results in high-efficiency spontaneous radiation of a short-wavelength wave at the second stage. According to the simulations performed for electron bunches with the parameters typical for modern photoinjectors, the cascade regime ensures radiation in the subterahertz frequency range with efficiencies from 10% (in regular systems) up to 30%–50% (in profiled systems).
Tunable giant Rashba-type spin splitting in PtSe2/MoSe2 heterostructure
Authors: Xiang Longjun , Ke Youqi , Zhang Qingyun
Published: November 2019

We report a giant Rashba-type spin splitting in two-dimensional heterostructure PtSe2/MoSe2 with first-principles calculations. We obtain a large value of spin splitting energy 110 meV at the momentum offset k0 = 0.23 Å−1 around the Γ point, arising from the emerging strong interfacial spin-orbital coupling induced by the hybridization between PtSe2 and MoSe2. Moreover, we find that the band dispersion close to the valence band maximum around the Γ point can be well approximated by the generalized Rashba Hamiltonian H(k||)=−ℏ2k||22m+ck||+ αRσ→·(k→||×z→). It is found that the generalized Rashba constant ηR=c+αR in PtSe2/MoSe2 is as large as 1.3 eV⋅Å and, importantly, ηR can be effectively tuned by biaxial strain and external out-of-plane electrical field, presenting a potential application for the spin field-effect transistor (SFET). In addition, with the spin-valley physics at K/K′ points in monolayer MoSe2, we propose a promising model for SFETs with optovalleytronic spin injection based on a PtSe2/MoSe2 heterostructure.

Published: November 2019

Understanding the electronic structures at the interfaces of wide bandgap oxide heterostructures is crucial for the rational design of oxide-based optoelectronic devices with novel functionality and improved performance. In this work, the electronic band diagram at a ZnO/α-Ga2O3 n-n isotype heterojunction is investigated by depth-profile x-ray photoemission spectroscopy (XPS). The directly measured valence-band offset is −0.61 ± 0.1 eV and a type-I (straddling gap) band alignment is formed at the ZnO/α-Ga2O3 heterointerface. As probed by the depth profile of core-levels and VB-XPS, the formation of an interfacial layer is observed due to Ga and Zn interdiffusion, where charged interfacial states result in the downward and upward band-bending at the ZnO and α-Ga2O3 sides, respectively. The influence of band bending and band discontinuity at the interface is confirmed by the rectifying characteristics in the Au/α-Ga2O3/ZnO heterojunction with electron accumulation at its interface. Taking the thermionic-field emission and band-to-band tunneling mechanisms into account, the simulated transport properties agrees well with the reported I-V characteristics of Au/α-Ga2O3/ZnO avalanche photodiode, a further validation of the deduced band alignment of the heterostructure.
Metal–organic frameworks under pressure
Authors: Collings Ines E. , Goodwin Andrew L.
Published: November 2019

Metal–organic frameworks (MOFs) are a broad and interesting class of materials known for their mechanical flexibility. As such, their response to pressure is usually extreme and often counterintuitive. This tutorial review surveys the structural response of MOFs to pressure as observed experimentally. It describes the experimental tools exploited in high-pressure crystallographic measurements and highlights some of the experiment design choices that influence the actual physics probed in these measurements. The main focus of the review is a description of the key pressure-driven structural responses exhibited by MOFs: isosymmetric compression, including negative compressibility; symmetry-lowering transitions; changes in connectivity; amorphization; and inclusion of the pressure-transmitting medium within the MOF pores. The review concludes both by highlighting some functional implications of these responses and by flagging some future directions for the field.
Low temperature protein refolding suggested by molecular simulation
Authors: Kozuch Daniel J. , Stillinger Frank H. , Debenedetti Pablo G.
Published: November 2019

The function of critical biological materials, such as proteins, is intrinsically tied to their structure, and this structure is in turn heavily dependent on the properties of the solvent, most commonly water or dilute aqueous solutions. As water is known to exhibit anomalous properties, especially at supercooled temperatures, it is natural to ask how these properties might impact the thermodynamics of protein folding. To investigate this question, we use molecular simulation to explore the behavior of a model miniprotein, Trp-cage, as low as 70 K below the freezing point of the solvent at ambient pressure. Surprisingly, we find that while the expected cold denaturation of the protein is observed at moderate supercooling, further cooling to more than 55 K below the freezing point leads to cold refolding of the protein. Structural and hydrogen bonding analysis suggests that this refolding is driven by the desolvation of the protein’s hydrophobic core, likely related to the pronounced decrease in density at this temperature. Beyond their intrinsic fundamental interest, these results have implications for cryomicroscopy and cryopreservation, where biological materials are often transiently subjected to these extreme conditions.
Tuning critical phase transition in VO2 via interfacial control of normal and shear strain

Published: November 2019

Interface strain plays a key role in creating the emergent functional properties of heteroepitaxially correlated materials. Strain that originates from the lattice mismatch of thin films and substrates has been widely studied to support the creation of desired functionalities. However, the shear strain induced by the symmetry mismatch of heterostructures has rarely been considered. Here, we report evidence of twin domains of stabilized vanadium dioxide (VO2) epitaxial films grown on sapphire substrates with a miscut along the a-plane. A systematic investigation of lattice variations, including lattice rotations and lattice distortions, reveals that both normal strain and shear strain can be manipulated by vicinal sapphire surfaces using different miscut angles. Consequently, the critical phenomenon of metal-insulator transitions (MITs) in VO2 epitaxial films is strongly coupled with lattice variations. A significantly sharpened MIT transition, over four orders of magnitude in resistance change, is also achieved by controlling interfacial shear strain. Our results demonstrate that the degree of freedom of shear lattice deformation opens the door to fine-tune the critical properties of heterostructures of strongly correlated oxides to aid in the development of electronic devices.
Holistic assessment of consecutive interpretation
Authors: Lee Sang-Bin
Published: November 2019

The article aims to show how interpreter trainers holistically grade student performances. For this purpose,
experimental rating sessions were held for four undergraduate interpreter trainers. The raters were asked to think aloud their
quality judgments while holistically assessing six recordings of consecutive interpretation. Their concurrent verbal reports,
along with reflective reports, interview transcripts, and video recordings of computer screen activity, were collected and
analysed in detail. Findings revealed various facets of interpreting performance assessment, including what procedures the raters
followed, what aspects of the performance they focused on, what criteria they depended on for their judgment decisions, and why
two ratings of the same performance were divergent. This article also presents a tentative model for holistic rating of
consecutive interpretation.
The doubling of design in Walter Nash’s Rhetoric
Authors: Stacey David E.
Published: November 2019

This chapter takes as its point of departure a simple diagram
which appears at the beginning of Walter Nash’s (1989) Rhetoric: The Wit of
Persuasion. As argued, this diagram offers a key to
understanding Nash’s unique conception of classical, renaissance and modern
rhetoric. Focusing upon the rhetorical canon of
taxis/disposition, or arrangement, the chapter explores
how Nash celebrates the skill of writers of canonical literary texts, and of
canny speakers in everyday situations, to design powerful schemes of
persuasion. It is suggested that listeners and readers appreciate the aesthetic
realization of language designed to persuade. The author observes how Nash’s
approach is to encourage receivers of language actively to take power in
rhetorical situations by parodying and rewriting, in order to critically
understand and creatively revise these schemes of persuasion. These
observations are complemented by an analysis of a press conference held by US President Donald Trump’s first press secretary, Sean Spicer.
Common Language
Authors: Carter Ronald
Published: November 2019

This chapter takes further debates concerning the nature of
literary language and the presence of literariness in a range of discourses
by exploring the extent to which everyday conversational discourse displays
literary properties. The author argues that studies of literary discourse,
and of the continuities between literary and non-literary discourse, have
tended to focus on written language or on representations of spoken
discourse in fictional or dramatic dialogues. This emphasis has made for
questionable connections between literature, literacy and the written
language because it assumes that spoken language is no more than a less
patterned version of written language. Using the Cambridge and Nottingham
Corpus of Discourse in English (CANCODE), the author shows how verbal
inventiveness is pervasive in ordinary talk. The chapter concludes that
common, everyday language is far from being either everyday or
common – on the contrary, it is pervasively “poetic”.
Morphological sensitivity generalizes across modalities
Authors: Gafni Chen , Yablonski Maya , Ben-Shachar Michal
Published: November 2019

A growing body of psycholinguistic research suggests that visual and auditory word recognition involve
morphological decomposition: Individual morphemes are extracted and lexically accessed when participants are presented with
multi-morphemic stimuli. This view is supported by the Morpheme Interference Effect (MIE), where responses to pseudowords that
contain real morphemes are slower and less accurate than responses to pseudowords that contain invented morphemes. The MIE was
previously demonstrated primarily for visually presented stimuli. Here, we examine whether individuals’ sensitivity to
morphological structure generalizes across modalities. Participants performed a lexical decision task on visually and auditorily
presented Hebrew stimuli, including pseudowords derived from real or invented roots. The results show robust MIEs in both
modalities. We further show that visual MIE is consistently stronger than auditory MIE, both at the group level and at the
individual level. Finally, the data show a significant correlation between visual and auditory MIEs at the individual level. These
findings suggest that the MIE reflects a general sensitivity to morphological structure, which varies considerably across
individuals, but is largely consistent across modalities within individuals. Thus, we propose that the MIE captures an important
aspect of language processing, rather than a property specific to visual word recognition.
