Tropospheric carbonyl sulfide mass balance based on direct measurements of sulfur isotopes
Authors: Davidson Chen , Amrani Alon , Angert Alon 
Published: February 2021

Significance
Assessment for large-scale photosynthesis-climate feedbacks is needed. Carbonyl sulfide (COS) is an emerging proxy for the terrestrial photosynthesis. This proxy is limited by uncertainties related to the magnitudes of COS sources and sinks. Here, we demonstrate measurement-based assessments for the isotopic signal of: tropospheric COS, marine and anthropogenic COS emissions, and the isotopic fractionation of COS by plant uptake. All of these resulted in an isotopic mass balance for the COS budget which gives an important constraint for its sources.
L. V. Ščerba’s conception of language
Authors: Campbell-Thomson Olga 
Published: February 2021

Summary
This contribution offers an introduction to an essay by the Russian linguist Lev Vladimirovič Ščerba (1880–1944),
“О трояком аспекте языковых явлений и об эксперименте в языкознании” (“The threefold aspect of linguistic
phenomena and experiment in linguistics”), which was first published in 1931. This introduction is followed by an annotated
translation of Ščerba’s essay, proposed here for the first time to an English-speaking readership (Read the English translation at 10.1075/hl.00075.sce).
The critical introduction provides the backstory behind Ščerba’s conception of language as a means of helping the
reader to understand the connectedness of the various strands of his linguistic research. As is shown in our introduction,
Ščerba’s general distinction between linguistic raw material, the linguistic system and individual speech activity (the “threefold
aspect” alluded to in the title of his essay) serves as a framework to conceptualise metalinguistic practice and the relation of
the social dimension of language to its individual embodiment. An examination of the explanatory potential of Ščerba’s conception
of language for general linguistic problems suggests that his achievements lay in formulating a cohesive account of the
interconnectedness of language phenomena, identifying the linguistic means with which to understand the social nature of language,
and providing a theoretical basis for addressing the practical tasks of linguistics.
Cartography and selection in subjunctives and
interrogatives
Authors: Shlonsky Ur 
Published: February 2021

Abstract
On the assumption that a head c-selects the head
of its sister phrase, the question I try to answer is how to
implement selection of (indirect) questions and of subjunctive
complements. The question is relevant to cartography because the
head encoding Q (in interrogatives) and Mood-Subjunctive (in
subjunctive complement clauses) is presumably not the head of ForceP
but is merged lower down. I argue that it is always Force° which is
selected and the relation between Force° and material lower in the
left periphery is mediated by Agree. I further show that an Agree
probe in the left periphery, whose search domain is TP, must
implicate Fin, which I argue to be a phase head.
The syntax and information-structural semantics of negative
inversion in English and their implications for the theory of
focus
Authors: Honda Masatoshi 
Published: February 2021

Abstract
Negative inversion in English (e.g. Never
have I seen such a hippopotamus.) has inspired
empirical and theoretical interest because it shows complex
syntactic and semantic properties. One widely-held cartographic view
(e.g. Haegeman (2000,
2012)) has been that
negative inversion targets FocP in the CP domain, thereby satisfying
the NEG-criterion that requires the fronted NEG operator to be in a
Spec-Head configuration with the Foc head occupied by the inverted
auxiliary. Focusing on the syntax and information-structural
semantics of negative inversion, this study aims to develop the
criterial approach in terms of Cruschina’s (2011) split CP model, according to which
the Focus projection splits into two: Contrastive Focus (CFoc) and
Information Focus (IFoc). On the empirical side, drawing on Leonetti & Escandell-Vidal’s
(2009) insights into QP-fronting in Spanish, it is
demonstrated that negative inversion displays certain properties
related to (non-contrastive) polarity emphasis, which does not
contribute to a split between Focus and Presupposition. On the
theoretical side, it is argued that the properties relevant to
polarity emphasis in negative inversion are attributed to IFoc
fronting operations. The proposed analysis, a sophisticated version
of the criterial approach proposed in Haegeman (2000, 2012), naturally captures the
otherwise-unexplained polarity emphasis effects in negative
inversion.
Quantifictional binding without surface c-command in Mandarin
Chinese
Authors: Huang C.-T. James , Lin Jo-wang 
Published: February 2021

Abstract
This article discusses quantificational binding
without surface c-command in Mandarin Chinese. Jin (1998) pointed out that Chinese
quantificational NPs (Q-NPs) headed by mei ‘every’
are capable of binding out of containers such as sentential
subjects, relative clauses or adverbial clauses and there is a
subject/object asymmetry with respect to such binding. This
asymmetry, if correct, is reminiscent of the non-coreference rule on
pronominal anaphora which also displays an effect of subject/object
asymmetry (cf. Huang 1982
and Teng 1985) and would
call for a unifying treatment of the two phenomena. However,
contrary to Jin’s observation, this article shows that universal
Q-NPs in object position may actually bind out of their containers
just like universal Q-NP subjects, thus making it infeasible to
define a common locality domain to which both quantificational
binding and referential pronominal anaphora are sensitive. Instead,
this article argues that quantificational binding is an LF
phenomenon constrained by LF mechanisms. A minimum requirement for
quantificational binding is that the pronoun bound by a given
quantifier must be within the scope of that quantifier at LF. Though
this minimum requirement in principle enables Q-NPs to have high
scope, they are subject to other conditions such as the general
Condition on Scope Interpretation, which prevents a Q-NP from taking
scope over another one that c-commands it at surface structure. The
interaction of the two conditions explains why in some cases Q-NPs
may take high scope and bind a pronoun that they do not c-command
but not in some other cases. Backward quantificational binding, on
the other hand, is a result of the interaction of several
independently motivated mechanisms, including the possibility of
reconstruction at LF, the Chinese-specific non-coreference rule and
Chomsky’s Leftness Condition.
Attitudinal applicative in action
Authors: Lau Seng-Hian , Tsai Wei-Tien Dylan 
Published: February 2021

Abstract
In this study, we have investigated a rather
peculiar attitudinal construal of an applicative pronoun in Taiwan
Southern Min (TSM), which may well advance our understanding of the
split affectivity in Chinese dialects (cf. Tsai 2017), as exemplified below:

(1)

Guá
beh
lim
hōo
i
kàu-khuì!

1sg

want

drink

hoo

3sg

satisfied

“I want to drink to my satisfaction!”

It is also established that this type of
pronominal usage is not specific to TSM but widely observed
crosslinguistically (e.g., Vietnamese, Finnish, West Flemish, and
Dominican Spanish; see Greco
et al. 2017). Furthermore, the attitudinal applicative
pronoun, though non-referential, has its root in an Affectee
argument in association with the causative/passive marker of
hōo. As it turns out, the expression
hōo i has developed a speaker-oriented
construal, expressing the intention to carry out the activity to the
extreme.
Focus prosody by Korean learners of English
Authors: Liu Jun , Lee Yong-cheol 
Published: February 2021

AbstractThis study examined whether Korean learners of English attained native-like performance in English focus prosody by conducting production and perception experiments using digit strings. Language learners were classified into advanced-, intermediate-, and low-level groups according to their proficiency and compared with native speakers. Native speakers’ focus prosody was clearly prominent in the focus positions, and their post-focus positions were considerably compressed. Their focused digits were easy to detect, resulting in a 97% identification rate. Although advanced-level speakers produced acoustic cues quite similar to those of native speakers, their post-focus production did not resemble that of native speakers. Their identification rate was 81%, 16% lower than that of native speakers. Neither intermediate- nor low-level speakers’ focus-cueing changes were distinguished whatsoever in the focus and post-focus positions. Their identification rates were just over 10%, similar to the level of chance in a 10-digit string, implying that their focus productions were not sufficiently salient to be recognized in the experiment. The results suggest that second language acquisition is hindered by a negative transfer between English and Korean. The acquisition of second language focus prosody proceeds slowly; second language learners approach native-like proficiency once they become advanced.
Induced superconductivity in linear carbon chains and engineering of zero-bias peaks with geometric angles: a new approach
Authors: Norouzi Milad , Seyed-Yazdi Jamileh 
Published: February 2021

Abstract
We investigated the effect of slip angle, a geometric parameter named as α in superconducting quasi-one-dimensional carbon structures, by engendering resonant peak of linear carbon chains. We studied also the density of states and the effect of different slip angles on this structure. We found the interesting role of the slip angle, similar to the mixed superconducting state, creating a mass-like gap in the electron-hole excitation spectrum of the superconducting quasi-one-dimensional carbon structure. In the framework of the Dirac-Bogoliubov–de Gennes formalism, we investigated the transport properties in the superconducting linear carbon chain. The superconductor gap is taken to be a spin-singlet and spin-triplet superconducting state.

Published: February 2021

Abstract
The article demonstrates the fundamental possibility of creating microstructures for various functional purposes using the capabilities of the two-photon femtosecond polymerization method. The developed technological approach for creating a micro-optical holder for standard single-mode and multimode fibers is demonstrated. This type of holder can be used to manufacture a unit for optical matching of optical fibers with sensitive optical elements. The possibility of optical matching of fibers with a superconducting single-photon detector, an array system of bolometric superconducting microbridges, and spherical self-formed microlenses by near infrared-sensitive photopolymerization has been experimentally shown. The device manufacturing process was carried out in a combined single laser micromachining facility using femtosecond laser radiation for lithography with submicron resolution, texturing of the sensor surface, and the formation of microstructures for installing single-mode optical fibers.

-induced reactions at energies above the Coulomb barrier. Correlations between breakup modes and breakup components as well as their variations with the incident energy are investigated. The results will help us better understand the breakup effects of weakly bound nuclei on the suppression of a complete fusion, particularly for the above-barrier energies.
Modeling the integrity of course learning using percolation through intra-disciplinary connections
Authors: Gnitetskaya Tatyana , Tsoy Alexey 
Published: February 2021

Abstract
This article deals with the problem of modeling the assessment of the level of integrity of the physics course content learned by students. The need for such modeling is due to the need to bring education courses to online format. The degree of learning integrity is proposed to be established by modeling the percolation of intra-disciplinary connections established in the course structure. The modeling uses a graph model of intra-disciplinary connections (Gnitetskaya T.) and the principles of percolation theory (P-theory). The article provides some practical solutions for the use of P-theory. An algorithm has been developed that allows forming the topics of the physics course into the structure examined for percolation.

Published: February 2021

Abstract
The article considers the issue of ensuring compatibility in the implementation of the life cycle processes of technical systems. A logical diagram is given explaining the reasons for the decline in the quality of objects due to insufficient attention to the requirements for technical compatibility. On the basis of static calculations, the possibilities of improving the quality of systems of electric shut-off valves are presented due to the correct provision of technical compatibility of the form “product - lubricant”. Alternative options for combining valves and electric drives with reduced power and weight characteristics are proposed.

Improving the torque direct control method of the asynchronous motor in the converter using the active rectifier
Authors: Kozyaruk A.E , Tung Le Van , Vasilev Bogdan 
Published: February 2021

Abstract
The frequency converter study has shown that controlled rectifiers, also known as active rectifiers, have many advantages over uncontrolled rectifiers (diode bridges). The frequency converter with an active rectifier ensures that the input current is sinusoidal, the power factor is 1, the DC voltage constant at the output, the energy exchange according to bidirectional is between the load and grid. The voltage oriented control for the active rectifier will measure the grid voltage and use current control circuits or instantaneous power control circuits. The paper analyses the advantages of using the method of controlling the current in the rectifier circuit when working with the three-phase motor load. The torque direct control method of the motor is enhanced by selecting a new switch table of the voltage vector. The combining power, an active rectifier circuit, inverter, motor, and load create a complete electric drive system with improved working efficiency. The research results were verified by Matlab&Simulink software.
Influence of the relative location of distributed energy sources on the current protection of the electric network
Authors: Ivanchenko D I , Voytyuk I N , Smirnov A I 
Published: February 2021

Abstract
This article focuses on studying the influence of additional sources of electricity generation on the traditional distribution grid, which leads to a change in the direction of the power flow in the grid. Consequently, the sensitivity and speed of current protection are not provided due to the dynamic operation of distributed generation sources. This paper considers the effect of distributed generation on the protection of the power grid. A special emphasis is on problems which may occur in the power grid in the presence of distributed generation. The theoretical background of blinding and calculation of the effect is also presented. The studies presented are made by computer modelling in Matlab/Simulink.

Published: February 2021

Abstract
There are large differences between BIM and 3DGIS in model scale, data standards, information expression, etc., which brings great challenges to the conversion and integration between them. Through in-depth analysis of the current status, problems and difficulties about the integration of BIM models in 3DGIS scenes, aiming to the optimization of graphic information conversion, extraction and integration of attribute information, model light- weighting, shared scheduling, and integrated management of the entire life cycle, combined with IFC and CityGML, a framework for the transformation and integration of BIM models to 3DGIS scenes is proposed. Taking the management information system of the Changjiang Water Resources Committee as an example, after forming a preliminary three-dimensional terrain scene and building appearance model, the process of transforming and integrating a BIM building model into 3DGIS scene is discussed. The results show that the framework can effectively guide the entire process of conversion, publication, integration and application of BIM models in 3DGIS scene, and proves good practicability and operability.
A Novel Heuristic Method for Emergency Path Planning Based on Dynamic Spatial-Temporal Characteristics Map
Authors: Yang Bowen , Yuan Lei , Yan Jin , Ding Zhiming , Cai Zhi , Guo Limin 
Published: February 2021

Abstract
Emergency path planning technology is one of the hot research points in intelligent transportation systems. There are many methodologies and applications in emergency path planning. However, due to the complexity of the urban network and crowded road conditions, the difficulty of emergency path planning. The objective of emergency path planning is to get the vehicle out of the emergency areas and to its destination in the shortest time. Road congestion caused by emergency situations in cities directly affects the original road network structure. Then the weight of the original road network is no longer suitable as a basis for path recommendation and the value of edges of weight will change over time. To handle the dynamic road network, a novel situational time-stamp heuristic search algorithm (STH) is introduced for the situation space. This algorithm can effectively solve the problem of diversity of situational networks. STH can build a heuristic that adapts to time changes based on the map refresh time, and ensures that the path given in the time window T is optimal. Moreover, STH can give a pruning strategy according to the search time window T, which significantly improves the efficiency of the algorithm. Finally, the path planned by STH is better than the baseline algorithm.
