Clitic pronouns in Archaic Chinese
Authors: Djamouri Redouane , Paul Waltraud 
Published: December 2020

Abstract
This article provides evidence for the so far neglected existence of two clitic pronouns, yǐ
以 and yǔ
與, in Archaic Chinese (10th c. – 3rd c. BC) in immediately
verb-adjacent position: ‘yǐ/yǔ-V’. While yǔ only encodes the comitative/associative, yǐ encodes all kinds of (argument and adjunct) roles, depending on the semantics of the verb involved. We argue that the clitic pronouns
yǐ and yǔ can neither be analysed as stranded prepositions left behind after extraction
of their complement (as, e.g., in English) nor as orphan prepositions, i.e., PPs with an in situ null
pronoun as complement (as, e.g., in French). This ties in with the general ban against prepositions lacking an overt complement, observed
throughout the history of Chinese.
Optical conductivity of triple point fermions
Authors: Habibi Alireza , Farajollahpour Tohid , Jafari S A 
Published: December 2020

Abstract
As a low-energy effective theory on non-symmorphic lattices, we consider a generic triple point fermion Hamiltonian, which is parameterized by an angular parameter λ. We find strong λ dependence in both Drude and interband optical absorption of these systems. The deviation of the T
2 coefficient of the Drude weight from Dirac/Weyl fermions can be used as a quick way to optically distinguish the triple point degeneracies from the Dirac/Weyl degeneracies. At the particular λ = π/6 point, we find that the ‘helicity’ reversal optical transition matrix element is identically zero. Nevertheless, deviating from this point, the helicity reversal emerges as an absorption channel.

Abstract
Precise temporal and spatial knowledge of plasma potential has been a challenging task for decades. Gradient in values of plasma potential govern local electric fields providing insight into many other bulk plasma properties like particle drifts, confinement, transport barriers etc and plays a crucial role in determining stability of magnetically confined high temperature plasmas. In high temperature devices like tokamaks, plasma tends to develop edge bifurcations and results in edge transport barriers, which are a key tool for enhancing the plasma conﬁnement properties in magnetic fusion devices, which in turn requires knowledge of plasma potential. Conventional emissive probes (CEPs) in high temperature magnetically confined plasmas are not advisable owing to their inherent properties and tokamak parameters like high magnetic field, ultra-high vacuum pressure etc as well as tokamak geometry. A new type of emissive probe is becoming popular in recent times in such devices called the laser heated emissive probe (LHEP). Mostly, LaB6 and graphite are used as a LHEP tip owing to their inherent properties of thermal conductivity, low work function, high emissivity, higher lifetime etc. Similar with LaB6 in its mechanical and electrical properties, CeB6 is emerging as a promising candidate for LHEP. CeB6 is a better electron emitter than graphite and LaB6 at comparatively low power due to its lower work function. In this work, the heating dynamics of LaB6 and CeB6 heated by a CW CO2 laser with maximum power of 55 W have been reported. Theoretical and simulation models using Matlab and ANSYS have been developed to understand and explain the temperature gaining process of the probes. Simulation results are further validated by comparing them with experimentally measured data using an infrared camera.
Structural health monitoring system of construction facilities: enhanced training approach
Authors: Kats V 
Published: December 2020

Abstract
Structural health monitoring (SHM) of constructions under operating conditions becomes a relevant problem. When dealing with this problem the specific nature and environment conditions of the controlled facility should be considered. Therefore it is very important to continuously train the monitoring system with new data acquired from sensors. Current paper presents an approach of considering training the SHM system as training of defect evolution detection model. This method consists of four subsequent stages which allows to build and train defect evolution detection model on the acoustic emission sensor data. It includes data preparation stages (feature extraction, feature selection), outlier detection and training stage via proposed modification of the One-Class SVM anomaly detection method. Proposed approach was verified on real fuel and energy infrastructure facility. Obtained results give good grounds for utilizing the suggested approach in SHM systems with acoustic emission sensors allowing detection evolutionary defects in controlled facility which contributes to prevention of emergency situations that may have economic, social and ecological consequences.
Categorization of process names
Authors: Kholmatova Zamira 
Published: December 2020

Abstract
The categorization of processes according to their functionality is a key point to understand, how the user spent his or her time working with a computer. This task is not trivial due to the limited textual information available with applications. The existing approaches of this area commonly use predefined categories or clusterization techniques for applications, not processes. These techniques also do not describe the choice of these particular categories. In this paper, we describe our approach for the categorization of process names and explain, why we choose the set of categories we used. We evaluated the proposed approach on our collected data and got 81% correctly classified processes.
Data federation through on-demand queries in intelligent transport systems
Authors: Golovnin O K 
Published: December 2020

Abstract
The paper proposes a federated approach to data integration in intelligent transport systems when data are requested from various sources using the on-demand query technique rather than traditional approach when data are accumulated in a single storage. The proposed approach is designed to reduce the number of data manipulations, thereby increasing the processing speed and reducing the necessary computing resources. The study was carried out on synthetically generated data: 10 data sources are used; each of them consists of 650000 records. Data federation reduces the memory used by an average of 53%, while the time of virtual federal database creation is on average 71% less than the traditional integration approach implementation. The approach to data federation is designed for implementation in intelligent transport systems of a new generation, where it is required to process large amounts of data coming from various heterogeneous sources.

Published: December 2020

Abstract
In this work, a versatile method to increase the optical response of the oxide nanostructures is proposed. It combines a magnetron deposition of oxide matrix with the thermal deposition and aggregation of metallic nanoparticles, allowing the preparation of wide band gap oxide heterostructures with buried plasmonic Au nanoparticles. Thin layers of Si/TiO2 and Si/NiO were deposited by reactive magnetron sputtering in a 2D nanostructure, followed by 2.5 nm gold layer thermal deposition and in N2 thermal annealing at 550 °C to induce the growth of the Au nanoparticles. Then Si/TiO2/AuNP and Si/NiO/AuNP were covered with TiO2 and NiO respectively. The reflectance maximum of the LSPR band appeared at around 700 ÷ 720 nm for both heterostructures. It was demonstrated that both Si/TiO2/AuNP/TiO2 and Si/NiO/AuNP/NiO heterostructures can enhance optical response in comparison with Si/TiO2 and Si/NiO. The results obtained indicate a broad prospect of using the formed structures in the field of integrated optoelectronic devices.

Published: December 2020

Abstract
Graphene is considered as a promising material for electronic applications. In this work, micro-Raman spectroscopy, atomic force microscopy and Kelvin-probe force microscopy are used to study three epitaxial graphene samples: two commercially-available ones and one grown using a home-made setup. The obtained data indicates significant differences in homogeneity of strain and doping level, concentration of bilayer inclusions, surface topography and surface potential. Analysis of the measurements data allows us to establish connections between the topography of the samples and their structural properties. The results of these studies will help to understand the characteristics of transistors that are to be made on the basis of the studied samples.

Abstract
In this paper, we demonstrate an ability to produce aerosol metal Al nanoparticles with plasmon resonance in the ultraviolet region in a spark discharge generator in pure argon atmosphere. The sizes of the obtained primary particles with metal Al core and natural oxide shell in the range from 4 to 50 nm, which were collected in agglomerates with mean size from 190 to 260 nm, were observed. Simulation extinction spectra according to Mi theory for obtained particle ensembles were calculated. It was experimentally and theoretically found that obtained nanoparticles ensembles demonstrate the broad extinction peaks with maximum below 250 nm depending on the synthesis conditions.

This paper presents a study of a vacuum gauge with a sensitive element based on an array of carbon nanotubes. In the course of the study, a plasma chemical vapor deposition method was used, which allows one to obtain oriented CNT arrays on various substrates. A feature of this method is the use of catalytic centers. A model for calculating the parameters of the formed emission structure is constructed. The corresponding current-voltage characteristics are built. The results obtained during the study show that the vacuum gauge has a sensitivity of the order of 2.4·10−8 A/Pa, a speed of 4 seconds, at U = 20 V, and an energy consumption of 1.5 · 10−7 W.

Abstract
Passivation of the n-InP(100) surface with an aqueous solution of sodium sulphide (Na2S) has been investigated by spectroscopic photoluminescence (PL). After sulphide treatment the PL signal intensity of InP increased significantly and this increase is dependent on duration of sulphide passivation. The correlation of the increase in the PL intensity after sulphide treatment with the variation of the solution pH in contact with InP(100) surface has been established, that expect the possibility for optimization of the passivation process by monitoring the change of the solution pH value in the course of sulphide treatment of the semiconductor.

Authors: Rudyk N N , Il’in O I , Il’ina M V , Osotova O I , Fedotov A A 
Published: December 2020

Abstract
The influence of the temperature and Ti and TiN sublayer material on the height, diameter, density, and uniformity of carbon nanotubes (CNTs) growth is studied. It was found that on the TiN sublayer, CNTs form an array with a more uniform diameter distribution of CNTs than on the Ti sublayer (minimum dispersion 5.6 nm versus 8.1 nm). It is shown that for the Ti sublayer, with an increase in the growth temperature, an almost linear increase in the CNT height occurs. It was found that an increase in the CNT height is accompanied by a decrease in their diameter for both sublayers. For a given thickness of Ni, arrays with a density of 3–18 μm−2 were obtained on the Ti sublayer, and on a TiN sublayer in the range of 8–21 μm−2. The greatest uniformity of the surface distribution of CNTs is showed at 660 °C. CNT arrays on the Ti sublayer are characterized by a lower concentration of bundles than on the Ti sublayer.

Published: December 2020

Abstract
Nucleation effects were experimentally studied for ruthenium thin films grown by plasma-enhanced atomic layer deposition (PEALD) using O2 plasma. Bis(ethylcyclopentadienyl)ruthenium (II) (Ru(EtCp)2) was used as Ru precursor. The films with the thickness 10 nm on different underlying thin layers (interfaces), including Si, SiO2, Ta2O5, TiN, and TaN were deposited to investigate the effects of interfaces for nucleation of the Ru in ALD process. Some of the samples were previously processed in ammonia and oxygen plasma to enhance nucleation. The processes of forming barrier layers based on titanium and tantalum nitrides by plasma-enhanced atomic layer deposition were also studied. Films properties were evaluated by spectral ellipsometry, scanning electron microscopy and atomic force microscopy.

Published: December 2020

Abstract
In this work, it is experimentally shown that the etching of GaN or InGaN NWs in the KOH solution allows managing the morphology and optical properties of the nanowires array. Thinning rate of GaN nanowires is 5 times slower than the rate for InGaN nanowires along semi-polar and non-polar direction for nanowires with Ga-polar crystal structure. The diameter of the InGaN NWs decreases from 200-100 to 30-40 nm. After etching process, the intensity photoluminescence (PL) of nanowires and uniformity PL signal at all sample area increase.

Abstract
In this work we designed, synthesized and characterized luminescent metal nanoclusters (NCs) on human serum albumin (HSA) and immunoglobulins (Ig). We demonstrate that the approach developed allows one to determine the relative content of albumins and immunoglobulins in biologically relevant protein mixtures based on the luminescent properties of the NCs.

Published: December 2020

Abstract
The accumulation of lipofuscin (LF) in tissues is considered as one a hallmark of the aging process. Usually formed in yellow-brown pigment aggregates or granules primarily composed of lipid residues and proteins, the exact chemical composition of LF varies among tissues. LF of the retinal pigment epithelium (RPE) is known to contain byproducts of the visual cycle, including one of the fluorophores in LF bis-retinoid N-retinyl-N-retinylidene ethanolamine (A2E). The last is characterized by high photoreactivity and implicates in age-related macular degeneration. Photoinduced production of reactive oxygen species (ROS) is shown among the main modes of A2E toxicity although particular photochemistry of A2E have yet to be completely identified. In this work we study changes in chemical composition of LF granules of human RPE under light irradiation using vibrational spectroscopy (femtosecond broadband CARS) and mass-spectrometry (TOF-SIMS) approach accompanied by measurements of fluorescence properties of the LF.

Published: December 2020

Abstract
Quantum dot based monolithic edge-emitting semiconductor lasers at 1.25 µm are ideal sources for the generation of broad optical frequency combs for optical communication applications. In this work, InAs/InGaAs quantum dot lasers with different total laser length to absorber length ratio and with different p-doping concentrations in the GaAs barrier sections are investigated experimentally in dependence on the gain injection current and absorber reverse bias voltage. A smaller mode-locking area is found for the p-doped device in dependence on the laser biasing conditions. For the undoped active region 1.3 ps short pulse widths at a pulse repetition rate of 20 GHz with a pulse-to-pulse timing jitter of 111 fs are reported for an absorber section length of 12% to the total cavity length. For an undoped and p-doped device short pulse emission between 2.5 ps and 5.5 ps is attained and a shorter absorber section length of 8% or 5%.

Authors: Frolov I V , Radaev O A , Sergeev V A 
Published: December 2020

Abstract
The results of the study of changes in the dynamic characteristics of various spectral components of the full electroluminescence spectrum of green LEDs based on InGaN during tests with a pulsed current of increased density are presented. It was found that there is a decrease in the radiation power of the LED after 200 hours, as well as a decrease in the frequency of modulation of electroluminescence by 3 dB. It was found that a frequency change of 3 dB in the short-wavelength components of the spectrum is much larger than the long-wavelength ones. The results obtained indicate that the process of defect formation during testing proceeds more intensively in areas of a heterostructure with a low In concentration.
