Authors: Paul Sanjoy , Chen Tai-Siang , Houng Mau-Phon , Li Jian V. 
Published: May 2022

We report the synthesis of wide-bandgap β-Ga2O3 nanocrystalline thin films via the low-cost and non-vacuum-based liquid phase deposition (LPD) method. The morphological evolution of the nanocrystalline β-Ga2O3 grains was investigated as a function of the growth temperature, processing time, and pH value of the precursor solution. We successfully calcined gallium oxide hydroxide GaO(OH) through a 3-h annealing process at 800 °C to convert it into β-Ga2O3. We fabricated horizontal-structured Ni/β-Ga2O3 Schottky diodes and investigated the electrical characteristics pertinent to sensing temperature in the range of 100−800 K. The temperature sensitivity of the Ni/β-Ga2O3 Schottky-junction temperature sensors, defined as the temperature dependence of junction voltage at a fixed bias current of 10 µA, peaked at −2.924 mV/K in the range between 300 and 500 K. At room temperature, we measured a barrier height of 0.915 eV and a Richardson constant of 43.04 ± 0.01 A/cm2 K2 from the Ni/β-Ga2O3 Schottky junctions. These results indicate that the LPD-synthesized β-Ga2O3 material and devices hold promising potential for sensing applications especially at high temperatures.
Induction of human trophoblast stem-like cells from primed pluripotent stem cells

Published: May 2022

Significance
Treatment with bone morphogenetic protein 4 (BMP4) in human primed pluripotent stem cells (PSCs) for generating trophoblast lineage cells has sparked debate that the resulting cells are closer to amnion lineage cells rather than trophoblast. This study reports that trophoblast stem-like cells (TSLCs) can be generated from human primed PSCs by a short-term treatment of BMP4 without amnion lineage marker expression. In addition, we describe that TSLCs are self-renewing in long-term culture and bipotent as they can differentiate into functional extravillous trophoblasts and syncytiotrophoblasts. We propose an alternative method to generate an available model for studying human placental development from human primed PSCs.

Published: May 2022

Significance
Anterior thalamus exhibits significant functional changes with increasing age. While it has been associated with cognitive functions, the specific circuitry relevant for working memory remains unknown. The significance of this study is threefold: First, the anteroventral subdivision of anterior thalamic nuclei is necessary for working memory maintenance; second, aged mice showed a decrease in the excitability of anteroventral thalamic neurons, which correlated with a working memory impairment; and third, activating anteroventral thalamic neurons in aged mice was sufficient to improve their working memory.
A multi-dimensional comparison of the effectiveness and efficiency of association measures in collocation extraction
Authors: Deng Yaochen , Liu Dilin 
Published: May 2022

AbstractBecause of the ubiquity and importance of collocations in language use/learning, how to effectively and efficiently identify collocations has been a topic of interest. Although some studies have evaluated many of the existing association measures (AMs) used in the automatic identification of collocations, the results so far have been inconsistent and unclear due to various limitations of the existing studies. Hence, this study makes a multi-dimensional evaluation of the effectiveness and efficiency of seven major AMs in the identification of three types of collocations across five genres and seven corpora of different sizes. The results indicate that while a few AMs, such as Log Likelihood Ratio and Cubic Mutual Information (MI3), are consistently more effective and efficient than the other five AMs being examined, no one AM alone may be adequate in the identification of different types of collocations across different genres and corpus sizes. Research implications are also discussed.
“¿Triste estás? I don’t know nan molla”
Authors: Zhang Leticia-Tian , Vazquez-Calvo Boris 
Published: May 2022

Abstract
Fandubbing, or dubbing made by fans of any audiovisual product, is a linguistically and technologically
sophisticated enterprise enacted by many devoted fans. This study presents the case of Miree, a 24-year-old fandubber with more than 1 million subscribers on YouTube and more than 300 multilingual fandubbed songs. Using a
qualitative-interpretive approach, we conducted an in-depth interview with Miree and analyzed her top 30 videos by views to reveal
how Miree performed fandubbing, how she expressed her fan identity through fandubbing, and which were some of the implications of
fandubbing for language learning. Results show that Miree realized both interlinguistic genuine fandubbing and
intralinguistic parodic fandubbing, strategically adopting translanguaging to orchestrate a multimodal
performance, engage her fanbase, and activate several informal language learning opportunities and contexts afforded by
fandubbing.
Caloric stimulation of the labyrinth and some forgotten pioneers
Authors: Dasgupta Soumit , Mandala Marco , Vanspauwen Robby , Guneri Enis Alpin 
Published: May 2022

Introduction
Understanding the physiology of the caloric stimulation of the vestibular end organ was a seminal discovery in the history of neurotology. Robert Barany has been traditionally credited with this (1906). However, well before Barany, three scientists observed, qualified and quantified a similar phenomenon with different explanations. They were Charles Edouard Brown Sequard (1858), A Bornhardt (1876) and Benno Baginsky (1881).

Materials and methods
Articles with key words containing ‘caloric test’ and the ‘vestibular system’ were searched and studied from a historical perspective in scientific research repositories and journals on the history of medicine. Contemporaneous articles of the three scientists were analysed and inferences drawn.

Results and discussion
Charles Edouard Brown Sequard noticed the caloric effect on the ear causing giddiness in 1853, A Bornhardt observed nystagmus on application of ice cold water/hot iron rod to the semicircular canals in 1876 and Benno Baginsky in 1881 identified the correct pressure/temperature on the external/middle ear to elicit a caloric response. They also stumbled across key observations of vestibular physiology which were later confirmed in the 20th century.

Conclusions
This paper resurrects the works of these three forgotten pioneers and their contributions to our understanding of the physiology of the vestibular system.

Published: May 2022

Abstract
The minimal supersymmetric extension of the standard model (MSSM) is extended to the

SSM, whose local gauge group is

. To obtain the

SSM, we add new superfields to the MSSM, namely, three Higgs singlets

and right-handed neutrinos

. The charge conjugate and parity (CP) violating effects are considered to study the lepton electric dipole moment (EDM) in the

SSM. There are more CP violating phases in the

SSM than in the standard model (SM). In this model, several new parameters

are considered as CP violating phases; hence, there are new contributions to lepton EDMs. This is conducive to exploring the source of CP violation and probing new physics beyond the SM.

Published: May 2022

Abstract
In this paper, we present the universal structure of the alphabet of one-loop Feynman integrals. The letters in the alphabet are calculated using the Baikov representation with cuts. We consider both convergent and divergent cut integrals and observe that letters in the divergent cases can be easily obtained from convergent cases by applying certain limits. The letters are written as simple expressions in terms of various Gram determinants. The knowledge of the alphabet enables us to easily construct the canonical differential equations of the

form and aids in bootstrapping the symbols of the solutions.

Published: May 2022

Abstract
Large antennas play an important role in deep space exploration and astronomical research. However, their performances are inevitably affected by the main reflector surface deformation and sub-reflector displacement resulting from the factors of wind, temperature, and gravity, among which the effect of gravity is especially pronounced. In this work, a three-dimensional laser scanner was employed to measure the main reflector and sub-reflector gravitational deformation of the Tianjin 70 m antenna at different elevation angles. Here, we solved the antenna main reflector deformation and sub-reflector displacement, and analyzed the deformation law of the antenna under the action of gravity. A new measurement method of antenna main reflector deformation and sub-reflector displacement is realized by mutual verification of the measured results and theoretical simulations. This method will help to improve the antenna performance and provide a reference to optimize the design of large-aperture antennas.

Abstract
The integration of 5G mm-wave and Wi-Fi frequency bands becomes significant for upcoming 5G wireless applications for providing a large frequency ratio. This work presents a frequency reconfigurable hexagonal metamaterial resonator (HMR) antenna for Wi-Fi and a 5G mm-wave frequency band. A PIN diode is utilized to link up a microstrip patch antenna (MPA) with HMR to achieve integration of the Wi-Fi frequency band. The resonant frequency of the proposed antenna is 5 GHz (Wi-Fi) and 27.87 GHz with peak gain 2.33 dB and 7.12 dB, respectively. The operating bandwidth of the proposed antenna is 800 MHz (4.5-5.3 GHz) and 1020 MHz (27.35-28.37 GHz). The rogers RT5880 substrate with thickness 0.508 mm, dielectric constant 2.2, and loss tangent 0.009 has been used for designing the antenna. The overall size of the antenna is 30×23×0.508 mm3.

Published: May 2022

Abstract
Nowadays, smart health has been developing in the healthcare system by implementing the Internet of Things. One of the implementations of smart health is remote monitoring systems for rehabilitating patients such as stroke. Today, with the rising Covid-19 pandemic, patients undergoing rehabilitation at home have difficulties meeting with their doctors due to the moving restrictions. The healthcare facilities are focused on treating Covid-19 patients. These restrictions have caused doctors and patients not to meet regularly to collect their data on the rehabilitation progress. This research suggests building a prototype to monitor a post-stroke patient’s lower limb strength rehabilitation process by using embedded sensors and microcontrollers. The prototype will measure key components of the rehabilitation process and will be discussed in the later section of this paper.
Some Warnings About Quantum Space Gravimetry Enhance Earth Observations Project
Authors: Fiziev Plamen 
Published: May 2022

Abstract
In this paper, we discuss in brief some basic issues of quantum space gravimetry, related to standard approach of geodesy which is based on the Newton model of gravity and Euclidean geometry. We emphasize the need to apply relativistic gravity in practical high-precision geodesy.
Here we do not intend to solve the existing hard experimental and theoretical problems, being essential for the topic: development of quantum gravity, physics of dark matter and dark energy, novel physical principles of extended general relativity, in particular, a nonlinear superposition principle in general relativity and its extensions, and so on.
Rather, we point out the fundamental unsolved problems, which are substantial for quantum space gravimetry and future practical high-precision geodesy. We outline the possible ways for their study and decision. Thus, to some extend, the present paper is a program for further developments, not a presentation of the fnal solutions.
Our goal is to warn corresponding scientifc community about the ultimate necessity for going outside the frameworks of the formulated more than three century ago, and used up to now in geodesy, Newton gravity, together with Euclidian geometry.
At present, in the emerging high-precision geodesy one must replace them with modern models of gravity and corresponding non-Euclidean geometry.
Without using and further development of those issues, the interpretation of data obtained from high-precision measurements by satellites for geodetic use seems to be quite problematic, uncertain, and may be misleading for practitioners.
Analysis of up-to-date methods of non-destructive testing of performance properties of reinforced concrete building structures
Authors: Bredikhin V , Los K 
Published: May 2022

Abstract
In the process of engineering survey of the operated reinforced concrete structures of buildings and erections, various methods are being used. According to their approach, they are divided into two groups: destructive and non-destructive testing methods. The main disadvantage of destructive testing methods is the violation of the “testing integrity”, i.e. only the part of a structure is used in tests. When selecting core samples, for example, concrete cores from the “body“ of a structure, a new, essentially independent, structural element is formed. In other words, the behavior of a sample that is the part of a reinforced concrete structure may differ from the behavior of the same part in the structure as a whole during experimental testing. The noted shortcomings can affect the accuracy of the research results, which means that the answers to the questions posed before the technical inspection of a facility cannot be adequate. Methods of reinforced concrete structures’ inspection that partially or completely solve the problems of destructive testing are non-destructive methods. The paper concerns the system analysis of up-to-date methods of non-destructive testing of main performance properties of reinforced concrete structures.

Published: May 2022

Abstract
In the last years, research applications in the construction sector have taken a different turn due to rapid urbanization and the necessity to protect the environment and create a balance between the natural and built environments. Taking into account the fact that the thermal efficiency of buildings has an important influence over the environmental performances of the construction sector, the civil engineering specialists have tried to develop and use different new solutions in order to improve this essential building characteristic. Thus, different new materials have been used with the goal of reducing the overall thermal transmittance of the envelope elements and of the total energy consumption needed for heating and cooling. Perlite is one of the materials that have been considered for developing new energy efficient construction applications. The main goal of the present paper is to present all the relevant solutions that have been developed and used in the construction sector that consider perlite as a component part. The present study is the first part of a more extensive research program that takes under evaluation the possibility of using perlite as a thermal insulating material for different constructions.

Published: May 2022

Abstract
The effort to reduce the consumption generated by the use of buildings is one of the important objectives of today’s global society, involving authorities that regulate the energy performance of buildings, manufacturers of materials, specialists involved in the design and last but not least the occupants of buildings. The habits of the occupants of buildings regarding the indoor comfort temperature have a direct influence on the amount of energy consumed. The paper aims to highlight whether the results expected by applying the values recommended in the regulations are in line with the occupant’s habits. Based on a case study, the energy requirement for heating was assessed using different indoor temperatures, which were established in relation to the temperatures monitored in situ. The inside temperature values were monitored in three buildings, located in the third climatic zone of Romania. The article presents the results of the case study, emphasizing that indoor temperature control and monitoring are of high importance in the desired expectations for energy performance of buildings, to meet the sustainability objectives. Knowing the mutual influence between energy consumption and thermal comfort demands, building designers can find solutions to achieve energy conservation goals.

Experimental and simulated investigation of microdischarge characteristics in a pin-to-pin dielectric barrier discharge (DBD) reactor
Authors: HE Junwen , PENG Bangfa , JIANG Nan , SHANG Kefeng , LU Na , LI Jie , WU Yan 
Published: May 2022

Abstract
Both experimental and simulated studies of microdischarge (MD) are carried out in a dielectric barrier discharge with a pin-to-pin gap of 3.5 mm, ignited by a sinusoidal voltage with a peak voltage of 10 kV and a driving frequency of 5 kHz. Statistical results have shown that the probability of the single current pulse in the positive half-period (HP) reaches 73.6% under these conditions. Experimental results show that great luminous intensity is concentrated on the dielectric surface and the tip of the metal electrode. A 1D plasma fluid model is implemented by coupling the species continuity equations, electron energy density equations, Poisson equation, and Helmholtz equations to analyze the MD dynamics on the microscale. The simulated results are in good qualitative agreement with the experimental results. The simulated results show that the MD dynamics can be divided into three phases: the Townsend phase, the streamer propagation phase, and the discharge decay phase. During the streamer propagation phase, the electric field and electron density increase with the streamer propagation from the anode to the cathode, and their maximal values reach 625.48 Td and 2.31 × 1019 m−3, as well as 790.13 Td and 3.58 × 1019 m−3 in the positive and negative HP, respectively. Furthermore, a transient glow-like discharge is detected around the anode during the same period of streamer propagation. The formation of transient glow-like discharge is attributed to electrons drifting back to the anode, which is driven by the residual voltage in the air gap.
