Not just frequency, not just modality
Authors: Lorenz David , Tizón-Couto David
Published: June 2020

We review reduction and contraction in modalizing
expressions of the type V-to-Vinf from the perspective
of production, perception and mental representation. A corpus study of spoken
American English shows reduction/contraction as a continuous process which is
subject to phonological and communicative constraints. Generally, reduction
(articulatory ease) is restricted by a tendency to retain cues to morphological
structure (explicitness). For perception, a word-recognition experiment shows that
listeners use probabilities to cope with reduction; reduction also promotes
‘chunking’, i.e. accessing frequent sequences as single units. The combined evidence
suggests that ‘chunking’, reduction and contraction are not a self-propelled
process, even given high frequency or semantic bleaching. Rather, they are subject
to intuitive negotiations in speaker-hearer interaction. Methodologically, we make a
case for triangulating corpus and experimental data.
Conditionals, modality, and Schrödinger’s cat
Authors: Gabrielatos Costas
Published: June 2020

An intriguing characteristic of conditionals is that they
are modally dense constructions, without being modal markers themselves. This
chapter will examine the modal nature of conditionals through the lens of
construction grammar. It will be argued that the main utility of conditionals does
not lie in pairing conditions with consequents, nor in establishing the factuality
or actualisation of conditions and consequents, but in leaving issues of factuality
or actualisation unresolved. The chapter proposes that conditional constructions are
better regarded as environments of indeterminacy, in that they modalise what is
communicated through them. More precisely it will be argued that conditionals can be
usefully treated as the linguistic equivalent of quantum bits
(qubits). The chapter will also discuss the characteristics that
define the family of conditional constructions, and those differentiating between
family members.
A genre-based analysis of evaluative modality in multi-verb sequences in
English
Authors: Matsumoto Noriko
Published: June 2020

This paper explores the nature of evaluative modality in
multi-verb sequences with the deictic verb go as the first verb in
English. It deals with four types of multi-verb sequences: go-and-V,
go-to-V, go-V, and go-Ving. First, the paper proposes a
general classification of multi-verb sequences. Second, by using the concepts of
cotext and context, it shows the characteristics
of each type of multi-verb sequence from the viewpoints of inflection of the first
verb, the second verb selection, and genres of language use. Consequently, one
conclusion can be drawn: while the go-to-V, go-V, and
go-Ving sequences allow for a cotext-based interpretation, the
go-and-V sequence can allow for both cotext-based and
context-based interpretations.
On the (con)textual properties of must, have
to and shall
Authors: Furmaniak Gregory
Published: June 2020

This paper focuses on the (con)textual properties of root
must, shall and have to. It is
conducted within an evolving framework, Integrative Grammar. The account of the
three modal forms that is given here is integrative in two senses. First, it shows
that traditional semantic descriptions fail to account for how these forms are used
in discourse and that a comprehensive characterisation of their conditions of use
requires that (con)textual factors be taken into consideration. Two contextual
levels are considered: the distribution of the modal forms according to discourse
modes and their propensity to be used within specific discourse sequences. Second,
this study shows that these (con)textual features and the forms’ semantic, pragmatic
and even syntactic properties are interconnected and throw light upon one
another.
“The future elected government should fully represent the interests of Hongkong
people”
Authors: Biewer Carolin , Lehnen Lisa , Schulz Ninja
Published: June 2020

The modal system of English in its development provides an
ideal perspective on language variation and change. Since the sociocultural and
socio-historical situation in specific postcolonial communities promotes diversity
among New Englishes, it is likely to also affect their modal systems. In this paper,
we seek to identify patterns in the use of modalising expressions in Hong Kong
English in relation to topic, genre and the larger socio-historical context. Our
diachronic study of the frequency and function of selected modal verbs in press news
reports from the DC-HKE reveals a peak in the use of back-shifted
will and deontic should between 1988–1992 that
seems to be closely linked to developments of the genre and socio-political changes
in Hong Kong.
Emergent complex noun phrases
Authors: Stoenica Ioana-Maria , Pekarek Doehler Simona , Horlacher Anne-Sylvie
Published: June 2020

In this paper, we document the temporal and contingent nature of noun phrases (NPs). Focusing on relativized NPs, we show that they are produced as an interactional accomplishment, emerging from how participants adapt to each other’s verbal and non-verbal conduct. Based on 20 hours of French conversation, we identify two types of emergent complex NPs, and document their interactional working: Those resulting from a current speaker’s adding on a relative clause increment to his/her preceding turn; and those resulting from a next speaker’s production of such an increment, yielding jointly constructed NPs. We discuss implications for our understanding of the NP as an emergent unit, of the subordinate (or not) status of relative clauses, and of the notion of increment.
Asserting no-problemness in Spanish
Authors: Raymond Chase Wesley , Fox Barbara A.
Published: June 2020

While much is known about noun phrases from morphosyntactic and typological perspectives, the study of nominal elements in interaction is just beginning. We contribute to this new area by exploring the interactional functions of the Spanish indefinite determiner ningún (‘any’, ‘no’) in the formula No hay (ningún) problema (‘there isn’t (any) problem’). We find that action and sequential environment are crucial in distinguishing between speakers’ uses of the noun phrases problema and ningún problema, with the determiner deployed to upgrade the assertion of no-problemness compared to the version without the determiner. We use our analysis of these particular formulae to offer a theoretical and methodological contribution to the study of noun phrases in interaction, focusing on the generalizability of findings.
Policymaking in a low-trust state: legitimacy, state capacity, and responses to COVID-19 in Hong Kong
Authors: Hartley Kris , Jarvis Darryl S L
Published: June 2020

With indiscriminate geographic and socio-economic reach, COVID-19 has visited destruction of life and livelihoods on a largely unprepared world and can arguably be declared the new millennium’s most trying test of state capacity. Governments are facing an urgent mandate to mobilize quickly and comprehensively in response, drawing not only on public resources and coordination capabilities but also on the cooperation and buy-in of civil society. Political and institutional legitimacy are crucial determinants of effective crisis management, and low-trust states lacking such legitimacy suffer a profound disadvantage. Social and economic crises attending the COVID-19 pandemic thus invite scholarly reflection about public attitudes, social leadership, and the role of social and institutional memory in the context of systemic disruption. This article examines Hong Kong as a case where failure to respond effectively could have been expected due to low levels of public trust and political legitimacy, but where, in fact, crisis response was unexpectedly successful. The case exposes underdevelopment in scholarly assumptions about the connections among political legitimacy, societal capacity, and crisis response capabilities. As such, this calls for a more nuanced understanding of how social behaviours and norms are structured and reproduced amidst existential uncertainties and policy ambiguities caused by sudden and convergent crises, and how these can themselves generate resources that bolster societal capacity in the fight against pandemics.

Influence of Quantum Feedback Control on Excitation Energy Transfer*
Authors: Zong Xiao-Lan , Song Wei , Yang Ming , Cao Zhuo-Liang
Published: June 2020

Excitation energy transfer (EET) plays a vital role in many areas of physics and biology processes. Here we address the role of quantum-jump-based feedback control in the efficiency of EET through a chain model. Usually, the decoherence caused by dissipative noise is detrimental to the transfer efficiency. We demonstrate that feedback control can always enhance the efficiency of EET and the dependence of different feedback controls is also discussed in detail. In addition, we investigate the strategy to enhance the efficiency of EET in the Fenna–Matthews–Olson complex as a prototype for larger photosynthetic energy transfer systems.

Published: June 2020

We report a continuous-wave end-pumped Nd:YVO4 zigzag slab laser with multilayer amplified spontaneous emission (ASE) absorbing coatings. The coatings are deposited on the slab faces. A five-layer structure consists of SiO2-Ti-SiO2-Ti-Au, and the thicknesses are 2520 nm, 10 nm, 160 nm, 24 nm and 200 nm, respectively. The designed coatings show good performance for the ASE control in the experimental tests. A stable-unstable hybrid laser oscillator along orthogonal directions in the slab aperture is further configured, achieving the 117W output at a pump of 328 W. The beam quality factors M2 in the unstable direction and stable direction are 1.57 and 1.66, respectively.

Published: June 2020

The terahertz (THz) temporal waveform and spectrum from a longitudinal electrically biased femtosecond filament is studied experimentally. The initial direction of the electron motion inside the unbiased filament plasma is deduced from the transformation of the THz temporal waveform with applied fields of opposite polarities. Furthermore, a spectrum shift to lower frequency of the THz spectrum is observed in the presence of a biased field. It agrees well with theoretical predictions.

Authors: Wang Jiayu , Zhou Qiang , Guo Siyang , Huang Yanping , Huang Xiaoli , Wang Lu , Li Fangfei , Cui Tian
Published: June 2020

Silane (SiH4) is a promising hydrogen-rich compound for pursing high temperature superconducting. Previous high pressure measurements of Raman, x-ray diffraction and theoretical studies on SiH4 mainly focused on its polymorphic structures above 50 GPa, while the structure and the stability under lower pressure range are still unclear. Here we report an investigation of condensed SiH4 by Brillouin scattering measurements at high temperature up to 407 K and high pressure up to 18 GPa. Brillouin scattering frequencies of fluid SiH4 under compression are obtained under isothermal conditions of 300 K, 359 K and 407 K. The SiH4 becomes unstable with increasing temperature and subsequently decomposes into silicon and H2. We find that compression at room temperature induces two velocity anomalies corresponding to a fluid-solid state transition and a phase IV to phase V transition, respectively. Brillouin scattering spectra has been a powerful tool to investigate the fruitful phases and structure transitions in the hydrogen-rich compound under extreme conditions.

Published: June 2020

Polycrystalline BAsx (x = 0.80–1.10) compounds with different boron-to-arsenic elemental molar ratios were synthesized by a high-pressure and high-temperature sintering method. Compared with other ambient-pressure synthesis methods, high pressure can significantly promote the reaction speed as well as the reaction yield. As the content of arsenic increases from x = 0.91 to 1.10, the thermal conductivity of BAsx gradually increases from 53 to 65 W⋅m
−1⋅K
−1. Furthermore, the temperature dependence of thermal conductivities of these samples reveals an Umklapp scattering due to the increasing phonon population. This work provides a highly efficient method for polycrystalline BAs synthesis.
Water-Mediated Spontaneously Dynamic Oxygen Migration on Graphene Oxide with Structural Adaptivity for Biomolecule Adsorption*
Authors: Tu Yusong , Zhao Liang , Sun Jiajia , Wu Yuanyan , Zhou Xiaojie , Chen Liang , Lei Xiaoling , Fang Haiping , Shi Guosheng
Published: June 2020

We theoretically and experimentally show that, with water being adsorbed, the graphene oxide (GO) is converted to a spontaneously dynamic covalent material under ambient conditions, where the dominated epoxy and hydroxyl groups are mediated by water molecules to spontaneously break/reform their C–O bonds to achieve dynamic oxygen migration. This dynamic material presents structural adaptivity for response to biomolecule adsorption. Both density functional theory calculations and ab initio molecular dynamics simulations demonstrate that this spontaneously dynamic characteristics is attributed to the adsorption of water molecules, which sharply reduces the barriers of these oxygen migration reactions on GO to the level less than or comparable to the hydrogen bonding energy in liquid water.

Two-dimensional (2D) materials are playing more and more important roles in both basic sciences and industrial applications. For 2D materials, strain could tune the properties and enlarge applications. Since the growth of 2D materials on substrates is often accompanied by strain, the interaction between 2D materials and substrates is worthy of careful attention. Here we demonstrate the fabrication of strained monolayer silver arsenide (AgAs) on Ag(111) by molecular beam epitaxy, which shows one-dimensional stripe structures arising from uniaxial strain. The atomic geometric structure and electronic band structure are investigated by low energy electron diffraction, scanning tunneling microscopy, x-ray photoelectron spectroscopy, angle-resolved photoemission spectroscopy and first-principle calculations. Monolayer AgAs synthesized on Ag(111) provides a platform to study the physical properties of strained 2D materials.
Novel R-test measurement system to detect thermally induced volumetric accuracy in horizontal machine tools
Authors: Weng Lingtao , Zhang Dawei , Gao Weiguo , Tian Yanling , Liu Teng , Zheng Yingjie , Shi Kai
Published: June 2020

Because of uneven temperature distributions, machine tools can generate thermal errors, which significantly contribute to machining errors. Previous research has shown that thermal volumetric errors can be directly measured using optical methods or indirectly calculated using error mapping methods. However, these methods are limited to or restricted by specific working conditions. Therefore, our study focused on developing a novel R-test measurement system for realising accurate thermal volumetric error measurements. The R-test measurement system consists of a three-dimensional (3D) ball array plate, R-test detecting head, temperature monitoring module, and data processing module. This system allows the measurement of deviation in the X, Y, and Z directions simultaneously at different fixed points in a 3D cube. Furthermore, considering the temperature and thermally induced volumetric accuracy, it was possible to derive the deformation tendency of the machine tool. An uncertainty analysis and systematic error corrections were conducted. The measurement uncertainty of this system is approximately 4 μm. The thermal volumetric errors were examined using the developed R-test measurement system and an interferometer under the same thermal conditions. The experimental results indicated that the R-test measurement system was able to accurately and rapidly detect thermal volumetric errors. This system provides a measurement technique with a low level of uncertainty, high accuracy, and low cost, which can be used to measure, compensate, and control the thermally induced volumetric accuracy of horizontal machine tools.
Microstructured single-layer electrodes embedded in P(VDF-TrFE) for flexible and self-powered direction-sensitive strain sensors
Authors: Schäffner Philipp , Zirkl Martin , Schider Gerburg , Groten Jonas , Belegratis Maria Regina , Knoll Peter , Stadlober Barbara
Published: June 2020

Most flexible piezoelectric transducers have a vertical setup with top and bottom electrodes, which does not enable the selective, directional detection of mechanical stimuli. Here we present a paradigm shift in the design of such transducers by placing the electrodes in a single layer and fully embedding them in a ferroelectric layer. This approach enables a selective detection of in-plane strains with a linear, orientation-dependent response. Our transducers feature microstructured, densely interdigitated electrodes embedded in the ferroelectric copolymer P(VDF-TrFE) and show an in-plane strain sensitivity of up to 8.3 nC %−1 (21.3 V %−1), while being 23 times less sensitive to transversal loading, compared to vertical setup devices. The embedded electrodes cause a strong anisotropy for in-plane strain coupling and make it possible to distinguish both the bending orientation and the bending intensity on a time-variable curvilinear surface. A high power density of 2.3 mW cm−3 was achieved during a periodic bending movement at 90 Hz. In addition to a photolithography and electroplating-assisted method, we present an alignment-free, elegant microcapillary force-based process for scalable fabrication of embedded electrodes. The presented transducers have a high potential for application as energy-autonomous sensors for condition monitoring, robotics and wearables.
The interplay between local and non-local master equations: exact and approximated dynamics
Authors: Megier Nina , Smirne Andrea , Vacchini Bassano
Published: June 2020

Master equations are a useful tool to describe the evolution of open quantum systems. In order to characterize the mathematical features and the physical origin of the dynamics, it is often useful to consider different kinds of master equations for the same system. Here, we derive an exact connection between the time-local and the integro-differential descriptions, focusing on the class of commutative dynamics. The use of the damping-basis formalism allows us to devise a general procedure to go from one master equation to the other and vice versa, by working with functions of time and their Laplace transforms only. We further analyze the Lindbladian form of the time-local and the integro-differential master equations, where we account for the appearance of different sets of Lindbladian operators. In addition, we investigate a Redfield-like approximation, that transforms the exact integro-differential equation into a time-local one by means of a coarse graining in time. Besides relating the structure of the resulting master equation to those associated with the exact dynamics, we study the effects of the approximation on Markovianity. In particular, we show that, against expectation, the coarse graining in time can possibly introduce memory effects, leading to a violation of a divisibility property of the dynamics.
Intermittent percolation and the scale-free distribution of vegetation clusters
Authors: Martín Paula Villa , Domínguez-García Virginia , Muñoz Miguel A
Published: June 2020

Understanding the causes and effects of spatial vegetation patterns is a fundamental problem in ecology, especially because these can be used as early predictors of catastrophic shifts such as desertification processes. Empirical studies of the vegetation cover in some areas such as drylands and semiarid regions have revealed the existence of vegetation patches of broadly diverse sizes. In particular, the probability distribution of patch sizes can be fitted by a power law, i.e. vegetation patches are approximately scale free up to some maximum size. Different explanatory mechanisms, such as plant–plant interactions and plant-water feedback loops have been proposed to rationalize the emergence of such scale-free patterns, yet a full understanding has not been reached. Using a simple model for vegetation dynamics, we show that environmental temporal variability—a well-recognized feature of semiarid environments—promotes in a robust way (i.e. for a wide range of parameter values) the emergence of vegetation patches with broadly distributed cluster sizes. Furthermore, this result is related to a percolation phenomenon that occurs in an intermittent or fluctuating way. The model also reveals that the power-law exponents fitting the tails of the probability distributions depend on the overall vegetation-cover density, in agreement with empirical observations. This supports the idea that environmental variability plays a key role in the formation of scale-free vegetation patterns. From a practical viewpoint, this may be of importance to predict the effects that changes in environmental conditions may have in real ecosystems. From a theoretical side, our study sheds new light on a novel type of percolation phenomena occurring under temporally-varying external conditions, that still needs further work to be fully characterized.
Gravitation induced shrinkage of Mercury’s orbit*

Published: June 2020

In general relativity, Mercury’s orbit becomes approximately elliptical and the its perihelion has thus an additional advance. We demonstrate, meanwhile, that in comparison of those given by Newton’s theory of gravitation for the orbit of the Mercury, the circumference and the area are reduced by 40.39 km and 2.35 × 109 km2, respectively, besides the major-axis contraction pointed out recently, and all are produced by the curved space within Einstein's theory of gravitation. Since the resolution power of present astronomical distance measurement technology reaches one kilometer, the shrinkage of Mercury’s orbit can then be observable.
Identification of subsurface fluid flow using the 2D geoelectric method in Marunda, North Jakarta
Authors: Farhan M , Rosid M S
Published: June 2020

Jakarta is the most densely populated province in Indonesia and it will grow over time. This overwhelming population causes a decrease in the quality and supply of groundwater. Brines has been discovered in several areas in Jakarta. Several studies conducted by earth science researchers conclude that brine in Jakarta appears from either seawater intrusion or trapped connate water. This study focuses on the use of the geoelectric method to evaluate the groundwater quality problem in Kelurahan Marunda. Methods used in this study are resistivity, self-potential, and groundwater sampling. Conductivity, Salinity, pH and water table elevation are the parameters used in this study. These methods are done to observe subsurface groundwater quality, fluid flow and how far the seawater infiltrated. Based on the result of groundwater data of 40 wells, high conductivity and high salinity zones are found. High conductivity in this area affected mostly by the saline factor indicated by high salinity and neutral pH. The subsoil has low resistivity values showed by 2D resistivity data. Also, self-potential data displays a North-South groundwater subsurface fluid flow 1, 20 km from the coastline. Altogether, these data indicate seawater intrusion in Kelurahan Marunda, North Jakarta.

Published: June 2020

Programming was made to calculate the Ground Shear Strain (GSS) value of microtremor data using Python. Microtremor is a repetitive ground vibration that propagates in soils containing certain sources. The microtremor method can be used to determine the value of Ground Shear Strains (GSS). Ground Shear Strain can be used to characterize the impacts occur during earthquakes, such as liquefaction, soil cracking, land subsidence, landslides, and ground vibration. Analyzing GSS value can be used to obtain information about soil response of an earthquake as a disaster reconstruction in the mitigation effort. In this research, the data processing conducted by the following steps: (i) Processing data using geopsy software to get the values of predominant frequency (f
0) and amplification(A
0), (ii) Finding νs
30 value using USGS data, and (iii) Making python scripts for calculating microtremor data. The result of this research showed that calculating microtremor data can be done by using python software and has the same value as if using Microsoft excel.

Published: June 2020

Colloidal gadolinium nanoparticles (GdNPs) have been produced by using pulsed laser ablation (PLA) method. The synthesis in this study used a low-power neodymium yttrium aluminum garnet (Nd: YAG) laser (45 mJ). Pulse laser beam, which has specifications of 1064 nm, 7ns, 10 Hz, was focused on high-purity metal gadolinium (Gd) surface, which was placed into a spinach-extracted liquid, to produce GdNPs colloid. It is known that the spinach naturally contains iron (Fe), which is a quite high concentration from FeSO4.7H2O. The magnetic characteristics of iron are ferromagnetism, likewise, gadolinium. As the contrast agent, especially in MRI, the magnetic characteristics of the material are needed to improve the image quality. Colloidal GdNPs were successfully produced at a total concentration of 71 ppm after laser bombardment. The TEM image of GdNPS shows that these nanoparticles had a spherical shape. The average diameter of GdNPs was 15 nm.

This research is aimed at obtaining the characteristics of negative corona plasma discharge with the presence and absence of woven natural silk and to figure out morphological alteration of woven natural silk by negative corona plasma discharge and water absorption characteristics of irradiated woven natural silk. The plasma reactor used employed multi point-to-plane electrode configuration using 100 electrodes. The reactor is connected to a high DC power supply with the point electrodes with spacing and the plane electrode varies from 0.6 to 3.0 cm. The silk sample has a dimension of (10 × 10) cm2. Plasma irradiations were performed with a varied duration that ranged from 5 to 30 minutes. Sample testing was performed using SEM and water drop test. SEM testing results also show damages on the fabric surface compared to non-irradiated fabric. Meanwhile, the water drop test results reveal that optimum absorption for woven natural silk is at a distance of 2.4 cm for 30-minute irradiation. These settings resulted in an average absorption time of 10.28 seconds, which is way faster than absorption for non-irradiated fabric, at 48.88 seconds.
Analysis of variance for strip plot design with missing values: bias correction of the mean squares
Authors: Nisa K , Hamsyiah N , Usman M , Warsono
Published: June 2020

Missing values in strip plot design cause an unbalanced design. As a result, several problems occur in analyzing the data. This paper presents the estimation of two and three missing values from strip-plot design with the fixed model using the Yates approach. However, the estimation toward the missing values in strip-plot design causes bias on the treatment mean squares which is shown by its expected value. To omit the bias caused by the estimated values, a procedure of Satterthwaite-Cochran approximation is applied. The procedure corrects the bias and gives an adjusted analysis of variance for the hypothesis test.

Water purifying is an important process to get fresh water for human needs. Several treatments such as advanced filtering using activated carbon and chlorine have been done to get clean water. However, most of the previous treatments required complex maintenance and left a by product. The choice for disinfectant gas is going to ozone gas because it has a minor harmful impact on the environment. This work is to find related parameters and to formulate those parameters in the equation to predict disinfectant gas production in the silent discharge process. The theoretical analysis provides a general approach for the equation models and experimental results complete the required data for the regression technique to determine constants and terms in equation model at the saturated region. Finally, a proposed equation model has successfully produced a prediction curve that is matched with experimental results.

Metformin is an antidiabetic drug that can be obtained easily in pharmacies/on the market, because it is traded freely, so people can easily buy and consume it. Ferrous metal, aluminum metal, and zinc metals are metal quite easy to find and are often used by the public. Metformin and Ferrous metal, aluminum metal and zinc metals are metal are quite familiar in the community. This research aims to deconcentrate metformin which can be obtained easily in pharmacies / on the market by electrolysis method, using ferrous metal, aluminum metal, and zinc metals are as an anode and carbon as the cathode. Electrolysis of metformin has been carried out using ferrous metal, aluminum metal, and zinc metal as an anode. The success of the electrolysis process was seen with a decrease in the sample COD index. In the case without the addition of electrolytes using ferrous metals, the COD index of the sample reduction was very low (9-17%). This research aims to increase the success of the electrolysis process, by adding various kinds of electrolytes, such as acetic acid (weak electrolytes), hydrochloric acid (strong electrolytes), sodium chloride and Fenton reagents. The addition of electrolytes can increase electrolysis yield significantly. The interaction between metformin during electrolysis is traced to the possibility of changes in the chromophore group (with UV-Visible spectra) and the functional group (with FTIR spectra) of the sample. From the research data obtained information that there is a decrease and shift in UV-Visible spectra and changes in functional groups after the electrolysis process occurs. The best electrolysis percentage is obtained, after adding NaCl solution and Fenton’s reagent in the range of 50 -66%.

In this study, silica-rich zeolite was made at a ratio Si/Al = 30. The template used was cationic surfactant from quaternary ammonium, tetrapropylammonium bromide (TPAB) and cetyltrimethylammonium bromide (CTAB). The CMC for TPABr (n – C3H7)4N is 10−3 M, and spherical micelle of CTAB is 8.9x10−4 M. The concentration of the TPAB and CTAB which used in this study were 0.0325; 0.125; 0.25 and 0.5 M. The results show that the type of synthesized zeolites are silica-rich sodalite with the crystal size 216 A°. The use of quaternary ammonium-based templates can increase crystallinity and reduce the size of silica-rich sodalite crystal grains but remain in the mesopore material size range. The concentration of the tetrapropylammonium bromide (TPAB) template is very influential on surface area and pore volume, whereas for cetyltrimethylammonium bromide (CTAB) it affects surface area but not on pore volume. The largest surface area and pore volume of 96 m2/g and 3.4×10−2 obtained for silica-rich sodalite using a landfill template at small concentrations.

Inventory control in the industry has an important role in supply chain management to produce products according to management standards or quality standards based on consumer demand. In the apparel industry, inventory control is adjusted to the type of apparel product according to consumer demand. The research aims are to derive a multivariate inventory control model with multivariate capability analysis based on several types of apparel products as quality characteristics. The method in the research uses the T2 Hotelling multivariate control chart and the multivariate capability indices for analysis apparel inventory control by management specification standards. We derived the T2 Hotelling multivariate control chart and the multivariate capability indices using data with the assumption that multivariate data are controlled and has multivariate normal distribution Variable research uses quality characteristics that are grouped into two types of apparel products. This model is useful as a multivariate inventory control model that can manage the amount of production and supply of products based on probabilistic consumer demand.

Published: June 2020

Spontaneous Symmetry Breaking (SSB) is a method to generate mass for all elementary particles in the Standard Model (SM). Even so, it turns out that the Higgs mass term in the Higgs potential, which responsible for the SSB, does not scale invariant. Based on this problem, instead of using SSB from the SM to explain the origin of mass, we erase Higgs’s mass term from the SM Lagrangean and introduce a hidden sector Lagrangean to produce an alternative way to generate Higgs mass. We use Scalar Bilinear Condensate ineffective theory to obtain Higgs mass via the Higgs portal and generate the SSB. The hidden sector in this alternative model is described by an SU(N
C
A) gauge theory with U(1)3 flavor. In the calculation, we use the Mean-Field Approximation Lagrangean in obtaining the vacuum of the potential to get a Higgs mass term in this model.

The problem in private universities in the developing country is that they have many computers in the computer laboratory but do not have enough resources to maintain it. The part of the computer that is most frequently damaged is a hard disk drive due to unstable electricity and causes many computers to become inactive due to universities inability to replace it. In this study, we present comprehensive research on reviving existing inactive computers with minimal expenditure. We use a combination of PXE, DHCP, TFTP, and VHD to implement the Network Boot System (NBS). In addition, we conducted simulations to measure the client’s network booting time on HDD and SSD. The simulations were carried out using 15 client PCs booted simultaneously from NBS’s server using two different master images on HDD and SSD. We found that all of the inactive computers could work normally. The use of SSD could increase the performance of NBS significantly. The expenditure cost to use mainstream SSD for an NBS’s server is much lower than having to replace the HDD for the entire inactive computers. Those strengthen that an NBS is feasible to be used on low-cost laboratory computers.

The proposed method of rice growth classification model based on Convolutional Neural Network (CNN) which had implemented towards LANDSAT images gives the highest accuracy value of 83.4% with the following parameters including batch size 32, drop out 0.5 and band 432. The batch size value is inversely proportional to the level of accuracy obtained, which means the greater the batch size value, the smaller the average level of accuracy obtained, whereas there is no correlation between the change in the drop out value and the accuracy value and in general the best accuracy value in the drop out value is 0.5.

Information technology systems can improve efficiency, quality of service, security and improve the quality of diagnosis, especially in the incidence of neonatal jaundice, because the incidence of jaundice that is not monitored can cause increasingly severe problems so that it can cause kernicterus and can also cause death in neonatal. This paper is focused on analyzing the contribution of information technology systems to health problems especially neonatal jaundice. The study design uses a systematic literature review with international journals in electronic databases. Journal criteria used the Randomized Controlled Trial (RCT) technique from 2011-2019. This systematic literature review concludes that information technology systems have a role in health care, wherefrom several technologies have proven to be able to detect, diagnose, treatment and education that is easy, fast, effective and can be used whenever needed in overcoming the problem of neonatal jaundice. However, the use of information technology systems has not been comprehensive so that it needs development especially in areas with limited access.
