Honorifics in the marketplace
Authors: Lee Jiyoon , Brown Lucien 
Published: March 2022

AbstractThis paper analyzes how vendors and customers in Korean marketplaces use three distinct levels of addressee honorifics: the deferential‑supnitastyle, the polite ‑yostyle and the so-calledpanmal‘half speech’ style. The frequencies of these forms to some extent pattern with the relative ages of the participants; for example, vendors are more likely to usepanmaltowards customers who are relatively younger. However, the majority of interactions feature dynamic variation between different styles, which cannot be adequately explained by relative age. Rather, we see that participants use‑supnitastyle and ‑yoto index that they are speaking in their prescribed roles as “vendors” or “customers”. Meanwhile,panmalwas found to index two main forms of social meaning. It was used to mark stages of the interaction that were conversational, playful, or intimate, but also when speakers strategically indexed their authority or power as they tried to take the upper hand in price negotiations. This authoritative use ofpanmalwas accompanied by non-verbal behaviors such as large body postures, high chin positions and the withholding of gaze and bodily orientation. The paper contributes towards a growing body of research adopting an indexical approach to the use of honorifics, and demonstrates the importance of including analysis of multimodal features alongside the honorific forms themselves.
Traversable wormhole on the brane with non-exotic matter: a broader view
Authors: Sengupta Rikpratik , Ghosh Shounak , Kalam Mehedi , Ray Saibal 
Published: March 2022

Abstract
In this article, the possibility of construction of a traversable wormhole on the Randall–Sundrum braneworld with non-exotic matter employing the Kuchowicz potential has been studied. We have obtained the solution for the shape function of the wormhole and studied its properties along with validity of null energy condition. The junction conditions at the surface of the wormhole are used to evaluate the model parameters. We also evaluate the surface density and surface pressure for the wormhole. We study the geometrical nature of the wormhole and consider the radial and tangential tidal constraints on a traveller trying to traverse the wormhole. Besides, a linearized stability analysis is performed to obtain the region of stability for the wormhole. Our analysis, besides giving an estimate for the bulk equation of state (EoS) parameter, imposes restrictions on the brane tension, which is a very essential parameter in braneworld physics, and very interestingly the restrictions imposed by our physically plausible and traversable wormhole model are in conformity with those imposed by other braneworld geometries which are not associated with a wormhole solution. Besides, it is important to study such constraints imposed by geometrical objects such as wormholes on any gravity theory operating at high-energy scales like braneworld, as wormholes are believed to have been formed from massive compact objects of high energy densities. Also, we go on to justify that the possible detection of a wormhole may well indicate that we live on a three-brane universe.

Multifunctional phononic crystal filter for generating a nonlinear ultrasonic guided wave
Authors: Sun Chaoyu , Song Ailing , Xiang Yanxun , Xuan Fu-Zhen 
Published: March 2022

Abstract
Nonlinear guided waves have proven to be extremely sensitive to microscopic and mesoscopic damage in materials in recent years. However, many factors in measurement will bring non-damage-related interference signals into the nonlinear guided waves signal, which greatly restricts the detection accuracy in structural health monitor systems. In this paper, we propose a phononic crystal filter to purify the ultrasonic signal by filtering away both the needless mode of the primary wave and the second harmonic wave generated in the exciting stage. This method can guarantee the second harmonic signal is only generated by the S0 mode primary wave propagating in the inspection area. The design principle, theoretical analysis, and numerical simulations of the proposed filter are introduced, and the results demonstrate that our proposed filter can be applied in low-frequency S0 mode Lamb wave nonlinear harmonic wave testing. The research results promote the development of high-accuracy nonlinear damage location, imaging algorithm, and industrial applications.
Polymer curing assisted formation of optically visible sub-micron blisters of multilayer graphene for local strain engineering
Authors: Pandey Mukesh , Kumar Rakesh 
Published: March 2022

Abstract
The local or global straining techniques are used to modulate the electronic, vibrational and optical properties of the two-dimensional (2D) materials. However, manipulating the physical properties of a 2D material under a local strain is comparatively more challenging. In this work, we demonstrate an easy and efficient polymer curing assisted technique for the formation of optically visible multilayer graphene (MLG) blisters of different shapes and sizes. The detailed spectroscopic and morphological analyses have been employed for exploring the dynamics of the confined matter inside the sub-micron blisters, which confirms that the confined matter inside the blister is liquid (water). From further analyses, we find the nonlinear elastic plate model as an acceptable model under certain limits for the mechanical analyses of the MLG blisters over the (poly)vinyl alcohol (PVA) polymer film to estimate the MLG-substrate interfacial adhesion energy and confinement pressure inside the blisters. The findings open new pathways for exploiting the technique for the formation of sub-micron blisters of the 2D materials for local strain-engineering applications, as well as the temperature-controlled release of the confined matter.

Abstract
The International Atomic Energy Agency (IAEA) has organised programmes on the development, comparison and testing of environmental assessment models and approaches for estimating the radiation exposure of humans and wildlife since the 1980s. The latest of these programmes was called MODARIA (Modelling and Data for Radiological Impact Assessment) and was run in two phases from 2012 to 2015 (MODARIA I) and 2016 to 2019 (MODARIA II). Both phases of the MODARIA programme had the overall objective to improve capabilities in the field of environmental transfer of radionuclides and public and non-human biota exposures assessment, by means of acquisition of improved data for model testing and comparison, reaching consensus on modelling philosophies, approaches and parameter values and building an international forum for the exchange of information. This paper provides an overview of the work undertaken during both phases of the MODARIA programme and its outputs. The overall aims and objectives of a new programme to follow on from MODARIA are described.
Measurement of the electron energy distribution functions in low density RF plasmas through a tunable external RF filter
Authors: Jeon Sang-Bum , Park Ji-Hwan , Chung Chin-Wook 
Published: March 2022

Abstract
The electron energy distribution function (EEDF) measurement in radio frequency (RF) plasmas is of fundamental interests, especially in low-density RF capacitively coupled plasma. For this purpose, a new external filter with very high impedances is developed. The impedance of the filter at the fundamental and its harmonic frequencies (13.56, 27.12 and 40.68 MHz) through careful circuit design is maximized. Experimental verifications are performed by measuring the EEDFs in RF discharges. The result shows that the RF distortion in the EEDF measurement is significantly reduced by tuning the filter under various discharge conditions in an inductively coupled plasma. Accurate plasma densities can be obtained and the electron heating mode transition is observed through high-quality EEDF measurement in an capacitively coupled plasma, where RF plasma potential fluctuates severely.
A multiscale wavelet algorithm for atom tracking in STM movies
Authors: Messer P K , Henß A-K , Lamb D C , Wintterlin J 
Published: March 2022

Abstract
High-speed scanning tunneling microscopy (STM) data have become available that provide movies of time-dependent surface processes. To track adsorbed atoms and molecules in such data automatic routines are required. We introduce a multiresolution wavelet particle detection algorithm for this purpose. To identify the particles, the images are decomposed by means of a discrete wavelet transform into wavelet planes of different resolutions. An ‘à trous’ low-pass filter is applied. The coefficients from the wavelet planes are filtered to remove noise. Wavelet planes with significant coefficients from the particles are multiplied, and the product is transformed into a binary particle mask. The precision of the method is tested with data sets of adsorbed CO molecules and O atoms on a Ru(0001) surface. The algorithm can safely detect and localize these particles with high precision, even in the presence of the enhanced noise characteristic for high-speed, constant-height STM data. By linking the particle positions, we obtain extended trajectories with a resolution of ∼0.5 Å or better allowing us to investigate the detailed motion of single atoms on a surface.

Abstract
The current work investigates the influence of the substrate temperature on the photodetection capability of cadmium selenide (CdSe) thin films deposited through economically viable thermal evaporation technique on glass substrates. The substrate temperature varied from room temperature (30 °C to 250 °C). The existence of a single-phase of hexagonal structured CdSe was established from XRD patterns with dominant peaks along the (002) plane in all the samples. The SEM micrographs show the homogeneous surface of the films without any pinholes. The bandgap of the films was found to vary with the variation in the substrate temperature and the sample fabricated at 200 °C substrate temperature showed a bandgap of 2.00 eV. The light-dependent electrical analysis is also made to reveal the photodetection capability of the deposited CdSe films. The 200°C deposited CdSe film exhibits a higher responsivity of 8.07 × 10−2 A W−1 and a maximum detectivity of 6.66 × 109 Jones. The external quantum efficiency (EQE) was found to rise with the substrate temperature and a maximum value of 18.8% for the 200 °C deposited sample. The observed rise and decay times show a rapid response when the incident light intensity is changed from 1 to 5 mW cm−2.
Predictions of the alpha-decay half-lives of even–even superheavy nuclei using modified Gamow-like model
Authors: Azeez O K , Yahya W A , Saeed A A 
Published: March 2022

Abstract

α-decay half-lives of superheavy nuclei have been studied using modified Gamow-like model and improved empirical formulas. The empirical formulas used in the study are Viola-Seaborg semi-empirical formula, universal decay law (UDL), Denisov-Khudenko formula (DK), Royer formula, Wang formula, AKRE formula, and new Ren B (NRB) formula. New values of the adjustable parameters in the modified Gamow-like model have been obtained using a least square fit scheme and input data from the NUBASE2020 database. We found that only two adjustable parameters are sufficient to describe the α-decay half-lives of heavy and superheavy nuclei. We also obtained new coefficients for the seven empirical formulas using similar procedure. The modified Gamow-like model (MGLM) and improved empirical formulas are then used to calculate the α-decay half-lives of measured superheavy nuclei with Z = 100–118. The calculated root mean square errors indicate that the Royer, DK, and AKRE formulas are the best three empirical formulas for evaluating the α-decay half-lives of the superheavy nuclei. The five best performing empirical formulas, together with the MGLM, are then used to predict alpha-decay half-lives of unmeasured even–even superheavy nuclei with Z = 120–126. The Q

Improved phenomenological nuclear charge radius formulae with kernel ridge regression *
Authors: Ma Jian-Qin , Zhang Zhen-Hua 
Published: March 2022

Abstract
The kernel ridge regression (KRR) method with a Gaussian kernel is used to improve the description of the nuclear charge radius by several phenomenological formulae. The widely used

,

and

formulae, and their improved versions including isospin dependence, are adopted as examples. The parameters in these six formulae are refitted using the Levenberg–Marquardt method, which give better results than the previous versions. The radius for each nucleus is predicted with the KRR network, which is trained with the deviations between experimental and calculated nuclear charge radii. For each formula, the resultant root-mean-square deviations of 884 nuclei with proton number

and neutron number

can be reduced to about 0.017 fm after considering the modification by the KRR method. The extrapolation ability of the KRR method for the neutron-rich region is examined carefully and compared with the radial basis function method. It is found that the improved nuclear charge radius formulae using the KRR method can avoid the risk of overfitting, and have a good extrapolation ability. The influence of the ridge penalty term on the extrapolation ability of the KRR method is also discussed. Finally, the nuclear charge radii of several recently observed K and Ca isotopes are analyzed.
Neural decoding of semantic concepts: a systematic literature review
Authors: Rybář Milan , Daly Ian 
Published: March 2022

Abstract

Objective. Semantic concepts are coherent entities within our minds. They underpin our thought processes and are a part of the basis for our understanding of the world. Modern neuroscience research is increasingly exploring how individual semantic concepts are encoded within our brains and a number of studies are beginning to reveal key patterns of neural activity that underpin specific concepts. Building upon this basic understanding of the process of semantic neural encoding, neural engineers are beginning to explore tools and methods for semantic decoding: identifying which semantic concepts an individual is focused on at a given moment in time from recordings of their neural activity. In this paper we review the current literature on semantic neural decoding. Approach. We conducted this review according to the Preferred Reporting Items for Systematic reviews and Meta-Analysis (PRISMA) guidelines. Specifically, we assess the eligibility of published peer-reviewed reports via a search of PubMed and Google Scholar. We identify a total of 74 studies in which semantic neural decoding is used to attempt to identify individual semantic concepts from neural activity. Main results. Our review reveals how modern neuroscientific tools have been developed to allow decoding of individual concepts from a range of neuroimaging modalities. We discuss specific neuroimaging methods, experimental designs, and machine learning pipelines that are employed to aid the decoding of semantic concepts. We quantify the efficacy of semantic decoders by measuring information transfer rates. We also discuss current challenges presented by this research area and present some possible solutions. Finally, we discuss some possible emerging and speculative future directions for this research area. Significance. Semantic decoding is a rapidly growing area of research. However, despite its increasingly widespread popularity and use in neuroscientific research this is the first literature review focusing on this topic across neuroimaging modalities and with a focus on quantifying the efficacy of semantic decoders.
The effect of extraction time on the quality of brown seaweed Na-Alginate Sargassum polycisteum as the base material for SBK Edible Film
Authors: Latifah R N , Rahmania S , Rohmah B L 
Published: March 2022

Abstract
Brown seaweed is an alginate-producing seaweed because of its high polysaccharide hydrocolloid content. Alginate is one type of hydrocolloid by organic polymers in water. This study aimed to obtain a suitable method in producing sodium alginate to produce a large yield. The research method includes the preparation of seaweed, extraction, and purification of alginate using EDTA, and testing the quality of the resulting alginate. The results showed that the yield of alginate produced in this study was 18.47-24.31%. The viscosity and water content test results showed that the alginate yield was 892 cps with an extraction time of 6 hours and 14.82% (w/v). Functional group analysis revealed a mannonate fingerprint region that indicated the absorption peak from alginate characteristics. The ash content test produced is in the range of 14.25%-26.57%. The pH of Na-alginate is in the range between 8-10. Water vapor transmission rate is ranged from 10.13-11.56 g/m2.hours to edible film application.
Study of mixed binding agent La-MOF and chelex-100 by diffusive gradient in thin films (DGT) devices
Authors: Julianti S , Saefumillah A , Zulys A 
Published: March 2022

Abstract
The release of phosphor in the form of high phosphate from sediments to the aquatic system triggers a eutrophication process. It occurs due to the influence of the iron redox system where phosphate bound to iron(III) oxyhydroxide is reduced to iron(II) which will be released into aquatic systems under anoxic conditions. Therefore, developing an in-situ technique to measure the release of phosphor and iron simultaneously contributes to a better analysis. The method uses Lanthanum MOF, a porous material with a high surface area to bind labile phosphate species and Chelex-100 and bind iron(II) ions in Diffusive Gradient in Thin Films (DGT). The largest value of CDGT/Csolution for Iron(II) ion was 1.12, and for the labile phosphate species, the maximum value was 1.39 within 24 hours. Tests on variations in the pH solution obtained optimum results for Iron(II) ions, namely at pH 2.5 - 4.5. Meanwhile, the labile phosphate species produced the optimum result at a pH of 2.5-8.6. This study shows that the ability of the binding agent combination in the DGT tool to bind Iron(II) ions and labile phosphate species depends on the immersion (soaking) time and pH.
Atmospheric pressure plasma jet for surface material modification: a mini-review
Authors: Setiawan U H , Nurcahyo I F , Saraswati T E 
Published: March 2022

Abstract
Plasma jet is one of the methods for surface material modification that is economically and environmentally friendly. This method can be applied in ambient pressure that makes this method more feasible. The discharge of plasma from the plasma jet can be adjusted according to the design used. Carrier gas that is used in the plasma jet system can also be adapted to the needs or appropriate to the target material. The gases that can be used are helium, argon, etc. A variant gas flow rate will also affect the plasma species and the surface material characteristics produced. Modifying a material with certain compounds can be done by passing the active gases or vapors through the carrier gas. The use of the plasma jet method possibly converts the surface material to be hydrophobic or hydrophilic characteristics. Moreover, the plasma jet technique is applicable for various materials or substrates in any dimension. This review article will discuss the parameters applied, such as various designs, carrier gas, gas flow rates, power used in the plasma jet.

Abstract
Silica in amorphous form is one of the fillers that is indispensable for the industrial world, especially for the superior material industry. Amorphous silica in the form of cristobalite compounds are inert, soft, and have high porosity which is suitable to be used as certain filler materials. This research describes about the characterization of amorphous silica produced from the pyrolysis process of emulsifier silicon. The pyrolysis process was carried out in three-stages, starting from the separation of water, separation of the emulsifier material from silica compound at a temperature of 300oC followed by pyrolysis at a temperature of 700 oC. In this process, amorphous silica and carbon are formed at the end of the pyrolysis process. In this study, characterization was carried out using XRD to determine the phase of the composition of the compound, SEM EDX to determine the morphology, and XRF analysis to determine the purity of product composition. The results of the XRD shows that the amorphous silica formed. SEM-EDX analysis shows that the amorphous silica has spherical fine grain with average particle size 0.30006 ± 0.01722 |am. It was supported by XRF analysis that shows that the amorphous silica has SiO2 content 99,92%.
