Early Treatment in Acute Severe Encephalopathy Caused by ATP1A2 Mutation of Familial Hemiplegic Migraine Type 2: Case Report and Literature Review
Authors: Du Ying , Li Chuan , Duan Feng-ju , Zhao Chao , Zhang Wei 
Published: November 2019

AbstractFamilial hemiplegic migraine type 2 (FHM2) is an autosomal dominant inheritance disorder caused by ATP1A2 mutation, and the clinical spectrum is heterogeneous even with acute severe encephalopathy. However, up to now, early treatments against acute and severe attacks in FHM2 are still insufficient. Here, we report a 15-year-old female with intellectual disability due to FHM2 caused by a pathogenic ATP1A2 gene mutation, presenting mild-to-moderate headache at the onset, followed by confusion, complete right hemiparalysis, epileptic partial seizures, and conscious disturbance with rapid progression in acute attack. Brain magnetic resonance imaging (MRI) and magnetic resonance spectroscopy have revealed left extensive cerebral cortex edema, slightly decreased N-acetylaspartate for neuronal damage, and mildly increased lactate acid for mitochondrial dysfunction throughout the hemispheric swollen cortex. The patient is diagnosed as severe encephalopathy caused by FHM2. Based on literature review about pathophysiologic mechanism described in FHM2 recently, we use early treatments including prevention of glutamatergic excitotoxicity and protection of mitochondria function, as well as traditional antimigraine drug. The symptoms are all greatly improved and recovered within a short time, and follow-up MRI also shows complete disappearance of edema throughout the left hemispheric cortex. Altogether, the approach in our case may reduce the severity and duration of encephalopathy effectively, expend therapeutic options, and provide helpful references for acute severe encephalopathy in FHM2.
Escaping optimization traps: the role of cultural adaptation and cultural exaptation in facilitating open-ended cumulative dynamics
Authors: Winters James 
Published: November 2019

AbstractExplaining the origins of cumulative culture, and how it is maintained over long timescales, constitutes a challenge for theories of cultural evolution. Previous theoretical work has emphasized two fundamental causal processes: cultural adaptation (where technologies are refined towards a functional objective) and cultural exaptation (the repurposing of existing technologies towards a new functional goal). Yet, despite the prominence of cultural exaptation in theoretical explanations, this process is often absent from models and experiments of cumulative culture. Using an agent-based model, where agents attempt to solve problems in a high-dimensional problem space, the current paper investigates the relationship between cultural adaptation and cultural exaptation and produces three major findings. First, cultural dynamics often end up in optimization traps: here, the process of optimization causes the dynamics of change to cease, with populations entering a state of equilibrium. Second, escaping these optimization traps requires cultural dynamics to explore the problem space rapidly enough to create a moving target for optimization. This results in a positive feedback loop of open-ended growth in both the diversity and complexity of cultural solutions. Finally, the results helped delineate the roles played by social and asocial mechanisms: asocial mechanisms of innovation drive the emergence of cumulative culture and social mechanisms of within-group transmission help maintain these dynamics over long timescales.
What the music said: narrative listening across cultures
Authors: Margulis Elizabeth Hellmuth , Wong Patrick C. M. , Simchy-Gross Rhimmon , McAuley J. Devin 
Published: November 2019

AbstractInstrumental music can seem to tell engrossing stories without the use of words, but it is unclear what leads to this narrativization. Although past work has investigated narrative responses to abstract moving shapes, very little work has studied the emergence of narrative perceptions in response to nonlinguistic sound. We measured narrative responses to wordless Western and Chinese music in participants in the US and in a cluster of villages in a rural part of China using a Narrative Engagement (NE) scale developed specifically for this project. Despite profound differences in media exposure, musical habits, and narrative traditions, narrative listening was employed by many participants and associated with enjoyment in both groups; however, the excerpts that unleashed this response were culture-specific. We show that wordless sound is capable of triggering perceived narratives in two groups of listeners with highly distinct patterns of cultural exposure, reinforcing the notion that narrativization itself is a readily available mode of experiencing music. The particular sounds that trigger narrativization, however, rely on enculturation processes, as demonstrated by the within-culture consistency, but between-culture divergence in the specific excerpts that led to narrative engagement. Narratives can emerge in multiple modalities, including wordless sound, but association patterns specific to individual cultures critically shape how apparently abstract sound patterns come to acquire deep meaning and significance to people.
DJ-1 regulates the integrity and function of ER-mitochondria association through interaction with IP3R3-Grp75-VDAC1
Authors: Liu Yi , Ma Xiaopin , Fujioka Hisashi , Liu Jun , Chen Shengdi , Zhu Xiongwei 
Published: November 2019

Significance
Endoplasmic reticulum (ER) and mitochondria form close associations that serve as a critical signaling platform. Loss-of-function mutations in DJ-1 are associated with autosomal recessive early onset Parkinson’s disease (PD). We found that DJ-1 knockout caused significant impairments in the structure and function of ER-mitochondria association in neuronal cells and in vivo. Reduced DJ-1 was associated with deficits in ER-mitochondria association in the substantia nigra of sporadic PD. Our study identifies DJ-1 as a critical component of the macrocomplex containing IP3R3-Grp75-VDAC1 at mitochondria-associated membrane and as playing an important role in the regulation of the integrity and function of ER-mitochondria association. Our research offers insights into the regulation mechanism of ER-mitochondria association and the pathogenic mechanism of DJ-1 deficiency in PD.
Understanding, predicting, and tuning the fragility of vitrimeric polymers
Authors: Ciarella Simone , Biezemans Rutger A. , Janssen Liesbeth M. C. 
Published: November 2019

Significance
The intricate interplay between the molecular structure of a material and its emergent macroscopic dynamics lies at the heart of modern materials science. This interplay, however, remains notoriously poorly understood for glass-forming systems. The recent advent of vitrimers—a promising new class of recyclable high-performance polymers with anomalous glass-forming properties—revives the urgency to gain a full understanding of the elusive structure–dynamics link in glassy matter. We combine computer simulations and first-principles theory to rationally expose the structural origins of the complex glassy dynamics in vitrimers. Our findings provide cues for a better fundamental understanding of glass formation and may stimulate the development of sustainable amorphous materials with on-demand functionalities.
Native habitat mitigates feast–famine conditions faced by honey bees in an agricultural landscape
Authors: Dolezal Adam G. , St. Clair Ashley L. , Zhang Ge , Toth Amy L. , O’Neal Matthew E. 
Published: November 2019

SignificanceIndustrial-scale production of crops through monocultures has resulted in “green deserts” of reduced biodiversity in many areas worldwide. Such simplified landscapes may impact ecosystem services such as pollination. Here, we present a large-scale, longitudinal study of managed honey bee colonies in the context of corn and soybean monocultures. Our results reveal a brief burst of colony growth during soybean bloom, followed by a longer period of forage dearth, resulting in decline in several aspects of honey bee health at both colony and individual levels. We demonstrate this decline is reversible when honey bees have access to native, perennial plants (i.e., prairie). Our results suggest sustainable pollinator management in landscapes dominated by monocultures can be achieved through reintegration of native biodiversity.
Universal phase behaviors of intracellular lipid droplets
Authors: Shimobayashi Shunsuke F. , Ohsaki Yuki 
Published: November 2019

Significance
There is growing evidence suggesting that intracellular phase transitions play roles in biological functions. However, little is known about phase transitions of lipid droplets that are organelles involved in energy homeostasis. Here, we demonstrate a universal intracellular phase diagram of lipid droplets, consistent with the in vitro phase diagram, and reveal that cholesterol esters cause the liquid–liquid crystal phase transition under near-physiological conditions. We moreover combine in vivo and in vitro studies, together with the theory of confined liquid crystals, to suggest that the radial molecular alignments in the liquid crystallized lipid droplets are caused by an anchoring force at the droplet surface. These findings pave the way for a better understanding of their biological functions and diseases.
Dichotic listening training following neurological injury in adults
Authors: Purdy Mary , McCullagh Jennifer 
Published: November 2019

Purpose:
Injury to the dominant left brain hemisphere can lead to specific language deficits such as aphasia, or to the cognitive processes that support language such as attention and working memory. Language is heavily supported through the auditory modality, which is a key area of deficit in acquired language disorders, and recovery of auditory processing is a prerequisite to recovery of other language modalities. A specific auditory processing deficit that has been identified following neurologic injury is dichotic listening. Some researchers have suggested that dichotic listening can be strengthened through the use of a dichotic listening training paradigm, although the impact of this training for adults with neurological injury is unknown. The purpose of this study was to determine whether dichotic listening training improved dichotic listening performance as well as auditory comprehension in individuals with neurological injuries.

Method:
Five individuals with a history of acquired language deficits who met specific inclusion and exclusion criteria participated in the dichotic listening training for four to six weeks. Dichotic listening and language comprehension skills were evaluated pre- and post-training.

Results:
Results indicated all participants progressed through a range of dichotic listening tasks during training, and four of the five individuals improved on at least one of the dichotic listening tests post-treatment. All of the participants demonstrated some improvement in auditory processing/comprehension of complex commands.

Conclusions:
Dichotic listening training has the potential to positively influence dichotic listening and auditory comprehension skills in adults with neurological injury.

Authors: Murzin S P , Safin A I , Blokhin M V 
Published: November 2019

Abstract
By repetitively pulsed laser treatment with a frequency of 500 Hz was metal/semiconductor nanocomposite on a basis of zinc oxide nanowires created. An analysis of results made it possible to find that with described laser-induced vibroexcitation of samples, vibration speed increases for frequencies multiple to frequency of the initial oscillation, and when frequency is increasing the amplitude is decreasing. Samples heating particularities in consequence of laser irradiation were determined. Analysis of X-ray diffraction images showed that the zinc oxide creation on the porous copper-zinc alloy substrate occurs as a result thermal oxidation by the repetitively pulsed laser treatment. It is shown that intensification condition of mass transfer in a solid state of a metal material is a local non-stationary deformation that is produced by a highly-powered outer action. Using of synergies of thermal action and vibrations in a sound frequency range caused by laser irradiation, provides opportunity of a new approach realization for the structures creation of composite nanomaterials on a basis of zinc oxide in metal/semiconductor Cu/ZnO nanocomposite.
Multiport optical power splitter design based on coupled-mode theory
Authors: Butt M A , Kozlova E S 
Published: November 2019

Abstract
We proposed a multiport T-shaped 1 x 8 balanced optical power splitter design based on asymmetric vertical silicon slot waveguides working on the principle of coupled-mode theory (CMT). The scheme of the power splitter is unique which offers strong field confinement of TE-polarized light and delivers the light to four ports each on two opposite side of the chip. By shifting the slot towards the outer sideline of the bend, the bending losses are reduced to 80% as compared to standard symmetric slot waveguide.

In this article a new mathematical model for a laser metal ablation by ultra-short duration laser pulses is proposed. The computational process is based on a two-temperature hydrodynamic model for electrons and ions. Some improvements are made and wide-range equation of state for metals is included in model. The results of the computer simulation of ablation depth for aluminum and copper are compared with experimental data at a different laser fluency values. We obtained a good agreement between the experimental and calculated data on the ablation depth.

Authors: Khonina S N , Savelyev D A , Degtyarev S A , Azizian-Kalandaragh Y 
Published: November 2019

Abstract
In this work, we develop a mathematical apparatus to describe continuous subwavelength diffraction gratings for creation of cylindrical beams with arbitrary order. We consider special degenerated cases of gratings periods expressions and propose to introduce nonlinearity to avoid these cases. Also, we propose a metalens based on subwavelength relief that is intended to create the longitudinally polarized photonic needle. The element combines two functions: polarization and phase transformation of the incident beam. The element transforms the incident linearly polarized beam into the radially polarized beam. Simultaneously, the incident field is provided with axicon phase. The numerical simulation is provided with Comsol software. The simulation verifies the efficient creation of longitudinally polarized photonics needle.
Dynamics of two dipole-coupled superconducting qubits interacting with two independent cavity modes
Authors: Evseev M M , Bashkirov E K 
Published: November 2019

Abstract
In this paper, we have investigated the entanglement dynamics between two dipole-coupled superconducting qubits not resonantly interacting with two microwave modes of independent coplanar resonators. The case of different atom-field couplings has been under consideration. Using the dressed-states technique we have derived the exact solution of the evolution equation for separable initial qubits states and field modes in the vacuum states. On its basis the negativity as a measure of qubit-qubit entanglement has been calculated. The time dependence of negativity for different values of detuning between the qubits and fields frequencies, atom-field couplings and strength of the dipole-dipole interaction has been investigated for different separable initial qubits states.
In uence of Stark shift and detuning on atomic entanglement induced by a thermal eld of one-mode cavity
Authors: Gulsyannikova M O , Bashkirov E K 
Published: November 2019

Abstract
We considered a quantum model consisting of two effective two-level atoms not resonantly interacting with a single-mode thermal cavity eld through two-photon transitions. We explored the entanglement dynamics between two atoms, and studied the effect of the Stark shift and detuning on the entanglement. The results showed that for a separable initial atomic state the Stark shift and detuning enhance the amount of atom-atom entanglement induced by the thermal eld. For entangled atomic state these reduce the atom-atom entanglement oscillations.
Diffraction from excitonic diffraction grating
Authors: Kapitonov Yu V , Shapochkin P Yu , Petrov Yu V , Lovtcius V A , Eliseev S A , Efimov Yu P 
Published: November 2019

Abstract
In this paper we consider two methods for the theoretical modelling of the reflection and diffraction spectra from an excitonic diffraction grating made from a quantum well with spatial modulation of the exciton resonance. The modelling was performed in the single-scattering approximation, and by the step-by-step approximations of the exact solution of Maxwell’s equations. The expressions are obtained for the modulation of the inhomogeneous broadening of the exciton resonance. Theoretical results are compared with the experimental data for the quantum well grown on an ion irradiated substrate, and for a quantum well irradiated with ions after growth.

Authors: Kolesnikova M D , Lyubarskaya A V , Nesterenko D V , Soifer V A 
Published: November 2019

Abstract
In the present work, we study the influence of the Brewster effect on the resolution of optical system for optical edge detection. The estimation of resolution for initial and transformed images of optical objects is performed both theoretically and experimentally. Our research demonstrates that the image edge detection based on the transformation by the Brewster effect improves the resolution of the optical system approximately by the factor of 1.6.
Conditions improving of laser heating for forming of materials with a ferritic-martensitic structure
Authors: Murzin S P , Liedl G , Bielak R , Melnikov A A 
Published: November 2019

Abstract
High-strength dual phase ferritic-martensitic steels with a controlled amount of martensite have the most favorable combination of durability and plasticity compared to other low-alloy steels. The possibility of conditions improving of laser heating for forming sheet materials with a ferritic-martensitic structure has been determined. It is shown that the redistribution of the power density of the heat source allows this process to be performed without a significant local decrease in the profile thickness. A diffusion-cooled and high-frequency excited CO2 laser ROFIN DC 010 with a maximum output power of 1000 W was used as the laser source. To redistribute the laser power density, a diffractive optical element (DOE) was used. The region of plastic deformation is characterized by a local decrease the thickness profile, while microcracks and a discontinuity of the metal weren’t observed.

Published: November 2019

Abstract
An oblique incidence of polarized light pulses with different envelope shapes is considered: triangular, Gaussian, rectangular and in the form of giant laser pulses onto a flat inhomogeneous anisotropic layer with torsion of the optical axis and optical dispersion. The wavelength of an optical pulse carrier is close to the resonance wavelength of an inhomogeneous anisotropic layer. The problem of the propagation of s- and p-polarization waves through a layer, the reflection of impulses of cross-polarized components, the dependence of modulation coefficients during medium torsion and frequency detuning is considered.
