Hybrid State Engineering of Phase‐Change Metasurface for All‐Optical Cryptography

Chalcogenide material Ge2Sb2Te5 (GST) has bistable phases, the so‐called amorphous and crystalline phases that exhibit large refractive index contrast. It can be reversibly switched within a nanosecond time scale through applying thermal bias, especially optical or electrical pulse signals. Recently, GST has been exploited as an ingredient of all‐optical dynamic metasurfaces, thanks to its ultrafast and efficient switching functionality. However, most of these devices provide only two‐level switching functionality and this limitation hinders their application to diverse all‐optical systems. In this paper, the method to expand switching functionality of GST metasurfaces to three level through engineering thermo‐optically creatable hybrid state that is co‐existing state of amorphous and crystalline GST‐based meta‐atoms is proposed. Furthermore, the novel hologram technique is introduced for providing the visual information that is only recognizable in the hybrid state GST metasurface. Thanks to thermo‐optical complexity to make the hybrid state, the metasurface allows the realization of highly secured visual cryptography architecture without the complex optical setup. The phase‐change metasurface based on multi‐physical design has significant potential for applications such as all‐optical image encryption, security, and anti‐counterfeiting.
Charge Transport Behavior of Al-Doped ZnO Incorporated with Reduced Graphene Oxide Nanocomposite Thin Film

ZnO is utilized as a promising material for various electronic and energy areas due to its outstanding chemical stability, abundance, non-toxicity, and low cost. However, controlling electronic transport properties of ZnO by facile strategy is still necessary for wider applications. Here, we synthesized reduced graphene oxide incorporated Al-doped ZnO nanocomposite thin film prepared by the electrospray deposition method and investigated the electronic transport behavior. The electron transport in pristine Al-doped ZnO thin film is strongly affected by grain boundary scattering, but significant enhancement of carrier mobility is observed in reduced graphene oxide-incorporated Al-doped ZnO nanocomposite thin film. The results demonstrate that this hybrid strategy with graphene has an important effect on the charge transport behavior in ZnO polycrystalline materials.
Fishing gears and crafts used in Gumti river of Muradnagar upazila, Bangladesh

The study describes traditional fishing gears and crafts available at Gumti river of Muradnagar upazila in Cumilla district, Bangladesh. The study was carried out by the collection of primary data through surveying individual fishermen. We found that there are 6 fishing gears available in the study area. Among them, 5 types of the fishing net (i.e., cast nets, seine net, lift net, push net, gill net) and a kind of fishing trap was identified. We also found 4 different types of crafts, including dingi nauka, kosha nauka, chandi nauka, and soto tempu. Synthetic twines are used for net making, which increases the fishing efficiency significantly. The life span of these nets varies according to their building materials. Sun-drying was the best approach for net preservation rather than using any chemicals or medicine. Besides, traditionally mehogany, raintree, shill koroi, garjan, gamari, jarul, chapulis woods and bamboos were found to be boat construction materials. The boats are painted with tar or pitch and burn oil for the protection. No modern instruments such as a compass, life-saving equipment are used by these boats. Most of the boats are mechanized, i.e. operated by engine.
Implikasi Kebijakan Perdagangan ACFTA Pada Bawang Putih Impor di Indonesia: Model Permintaan Impor

Indonesia is the biggest importer of garlic in the world. Each country has a trade policy to control imports, and Indonesia is implementing a free trade agreement, namely ACFTA. The purpose of this study was to analyze the effect of the ACFTA trade policy on Indonesian garlic using the import demand model. The method in this study uses the Eagle-Granger cointegration test and error correction model (ECM). Stationary test results using augmented Dickey-Fuller indicate that each stationary variable at the first difference level. Cointegration test shows that import variables, per capita income, relative prices, production and consumption ratios, and dummy have a long-term balance. The relative price, the ratio of production and consumption, and the dummy have a significant effect on the demand for imported garlic in the long run. In the short term, import demand is affected by the ratio of production and consumption, and dummy tariffs.
Comprehensive analysis of the NME gene family functions in breast cancer

Background An increasing amount of research over recent years on the anti-metastasis function of the non-metastatic (NME) gene family has been challenged, with some studies identifying its involvement in the promotion of oncogenesis. Therefore, the specific functions of the NME gene family require redefining through a comprehensive analysis of tumor heterogeneity and survival benefit. However, the functions of NME genes have not been comprehensively investigated in breast cancer (BC). Methods In this study, ONCOMINE, GEPIA, Kaplan-Meier plotter, cBioPortal, String, and metascape databases were utilized for comparison of the mRNA expression, patient survival and network analysis of NME-associated signaling pathways in BC patients. Results The mRNA expression of NME1 and NME2 was significantly increased in BC. Additionally, high NME 1 and NME2 levels were related to poor overall survival (OS), while the upregulated expression of NME3, NME5, and NME7 indicated prolonged survival. Moreover, increased mRNA level, amplification, or deep deletions in the NME gene family were identified in approximately 41% (450/1098) of all included BC specimens. NME1 and NME2 genes displayed the highest correlation with genetic correlations of the human NME genes in BC. The following pathways were regulated by NME gene upregulation: R-HAS-380270: Recruitment of mitotic centrosome and complexes; GO:0006228: UTP biosynthetic process; R-HAS-380259: Loss of NlP from mitotic centrosomes; hsa03410: Base excision repair; and CORUM:3714: Pericenrin-GCP complex, which was significantly modulated by changes influencing the NME genes. Conclusions Collectively, our findings revealed that the elevated expression of NME1 and NME2 could act as a biomarker and predictive tool for BC patients with poor prognosis. Furthermore, our findings indicated that NME3, NME5, and NME7 might play the roles of tumor suppressor genes, which require validation through further experiments.
Converting alfalfa pasture into annual cropland achieved high productivity and kept soil organic carbon in a semiarid area

Converting alfalfa (Medicago sativa L.) into annual cropland (rotated cropland, RC) is commonly done to reuse degraded alfalfa pasture. However, it is a big challenge for RC to achieve high productivity and maintain high soil organic carbon (SOC) to the levels achieved by previous alfalfa pasture. We converted a long‐term alfalfa pasture into RC in 2010, and studied the effects of fertilization on soil moisture, crop productivity, and SOC in the RC and in continuous cropland (CC), both under plastic film mulching, from 2010 to 2018. Before the conversion, alfalfa pasture had a higher SOC (12.3%) and total N (7.7%) than CC. However, not only severe soil desiccation occurred, but the available P and inorganic‐N were only about 39.4 and 25.1% of levels for CC. After the conversion, soil moisture in RC (measured at 0–0.6 m depth) was up to CC levels only after 1 year, and was restored to 95.3 and 69.2% of CC levels at 0.6–2 and 2–5 m depths only after 9 years. Crop yield and biomass in RCF (RC with fertilization) were comparable to those for CCF (CC with fertilization) after two years from conversion due to the increased available P and inorganic‐N, and sufficient soil moisture restoration at 0–0.6 m depath. SOC in RC decreased by 8.1% over the 9 years, while RCF consistently kept SOC levels up to those of pre‐conversion alfalfa pasture. These findings help to eliminate concerns about the continuously low production and rapid decline of SOC in croplands converted from alfalfa and suggest ways to support sustainable high‐productivity and high SOC sequestration in dryland farming.
Realising transfer learning through convolutional neural network and support vector machine for mental task classification

Electroencephalogram (EEG) measures brainwaves that have been the widely used modality for brain – computer interface (BCI) applications. EEG signal with machine learning has gained substantial success in the BCI. However, the availability of limited training data, appropriate model selection and high false-positive rates are the challenges that need immediate attention. Therefore, in this Letter, the authors present a mental task classi ﬁ cation model based on the notion of transfer learning that addresses the issue of data scarcity, model selection and misclassi ﬁ cation ratio. In the framework, the proposed model uses pre-trained network for the extraction of diverse feature and classify using support vector machine. The authors employed four pre-trained networks to identify the optimal network for the proposed framework: Vgg16, Vgg19, Resnet18 and Resnet50. The highest classi ﬁ cation accuracy of 86.85% (using Resnet50) was achieved using transfer learning. Comparison results showed that convolutional neural network-based approach outperformed conventional machine learning approaches and hence it can be concluded that the EEG-based classi ﬁ cation of the mental task using transfer learning model could be used in developing a superior model despite the limited data availability.

Conclui-se que no estado de Alagoas, as notificações por acidentes ofídicos apresentaram um perfil semelhante entre os dois anos consecutivos, bem como, quando comparado com outros estudos realizados em outras regiões do país, tanto em relação à faixa etária mais acometida, quanto a predominância dos acidentes por ofídicos botrópicos.
Implementation of Failure Mode and Effect Analysis and Fault Tree Analysis in Paper Mill: A Case Study

A good quality control system is important to be implemented to increase productivity and minimize defects in products. One of the quality control methods is failure mode and effect analysis (FMEA). This study uses the FMEA to identify the causes of the defects and recommend the prevention methods to overcome the causes of the defects in an Indonesian paper mill. The risk priority number (RPN) is calculated by multiplying the severity, occurrence, and detection of the failures that have been determined. Unsymmetrical and tainted products are the most dominant defects in the paper mill. An inappropriate machine setting is the cause of unsymmetrical products with the highest RPN of 343. The second highest RPN is problems with bleaching machines that caused tainted products with an RPN value of 216. This study offers suggestions to Indonesian paper mill to prevent and minimize defective products.
A Review of Software Watermarking

The Internet is the hallmark of the age of technology and this technology is complemented by the presence of software which is one of the basic components of the operation of the network and it is used in almost all daily life aspects such as industry, commerce and others. Because the digital documents and objects can be easily replicated and distributed at an economically low cost and as the software is a type of digital object, the problem of software watermarking risen as related to how to protect data from piracy. Therefore, various techniques have been developed to protect codes from misusing and unauthorized alteration. Each of them is known as watermarking technology that protects data by inserting secret information into software, as an indicator of copyright ownership for this software. In this paper, the watermarked software will be explained in detail by defining the classification of watermarks software, models of attack, and methods used in software watermarking carried out by several researchers. It seems clearly that the method of ROP algorithm has given the highest accuracy results up to 100%
Mixed Methods Utilisation in Innovation Management Research: A Systematic Literature Review and Meta-Summary

The main purpose of this article is to explore the application of mixed methods research in the innovation management sub-discipline utilizing a systematic literature review and meta-summary analysis. Regardless of the growing number of studies in innovation management there is still a lack of research that integrates and synthesizes this body of knowledge. Our review of 93 articles from Web of Science and Scopus databases, including content analysis, presents trends and research background in innovation management that use the mixed methods approach. This study addresses the inconsistencies in the literature and presents a holistic picture of what existing empirical studies have found to date. In addition, we have developed an innovation management model based on selected theoretical lenses to enable future researchers in a given area to choose the appropriate method. The results of the meta-summary show that 50.54% articles from our dataset are related to partially mixed dominant sequential methods, 12.90% fully mixed dominant sequential methods and 11.83% fully mixed dominant concurrent methods. We identified several research gaps and provided a future research avenue in the context of innovation management. The article analyzes empirical papers, enables identification of problems in the current research and identifies trends in the area of the studied phenomenon. The results on the topic of mixed methods in innovation management and used tools have indicated that this issue is still in a premature phase but with an upward trend of research development.
Concentrations of Trace Elements in Bottled Water Consumed in Angono, Philippines

Introduction. We analyzed the concentrations of the trace elements [chromium (Cr), arsenic (As), cadmium (Cd),cesium (Cs), lead (Pb), thorium (Th), and uranium (U)] in commercial bottled water consumed in the town of Angono,Rizal province, Luzon island, Philippines to evaluate the health risks of the trace elements in drinking water. Thereare some arguments that water resources available in the Philippines are heavily polluted by various materials, inparticular heavy metal elements. Method. The concentrations of seven trace elements in commercial bottled water produced and consumed in thePhilippines were analyzed using a solution nebulization inductively coupled plasma mass spectrometry (SN−ICP−MS). Result. The concentrations of the trace elements except for Cs, which does not yet have a WHO guideline value,in the locally produced bottled water were below the WHO guideline values. The Cs concentrations (<0.6 μg/L) ofthe bottled water of the Philippines were generally similar to those of the bottled water produced and consumed inother countries such as Japan, China, and Indonesia. Conclusion. The concentrations of trace elements in bottled water consumed in Angono, Philippines can be regardedas being at safe levels, as well as those of daily life water (i.e. tap, well, and spring water) consumed in the said town.
Psychiatric comorbidity in substance abusing population in Garhwal hills of Uttarakhand

Background: Psychiatric morbidity occurs more frequently in patients with substance abuse than in the general population. Routine evaluation and treatment of psychiatric morbidity can be helpful in improving care of substance abusing population but such data are relatively meager from developing countries.Methods: This study was conducted in the Out-patient facility of the Department of Psychiatry, Veer Chandra Singh Garhwali Government Institute of Medical Science & Research, Srinagar (Uttarakhand), starting from 23 September 2015. One hundred consecutive treatment seeking subjects fulfilling international classification of diseases and related health problems, 10th Revision (ICD-10), criteria for mental and behavioral disorders due to psychoactive substance use were included in the study. All the participants were required to sign an informed consent approved by the institutional ethical committee before being enrolled in the study. All the subjects included in the study were administered a semi-structured Proforma to elicit the clinical and socio-demographic variables. Results: One hundred patients consisting of 95 men (95%) and 05 women (05%) were included. The average age of the sample was 39.68 years (SD=11.97). As for the socio-demographic variables other than age, 87% of the patients were married, 62% patients were living in nuclear families and 66% belonged to the rural areas. 79% patients were educated up to high school and above and only 06% were illiterate. 36 % of the subjects screened positive for psychiatric morbidity. Psychiatric morbidity was significant higher in unmarried people with less education (primary or less) and those living in nuclear families. Conclusions: Psychiatric comorbidity was found in 36% of the study subjects.
Minimum rights policies targeting people seeking protection in Denmark and Sweden

The temporary law changed the general view of Sweden in Europe. We used to be the generous country, and that affected us as a public agency, because this generous image has also characterized our approach. If you look around here in our office, the rooms are named after Malala, Raoul Wallenberg … all human rights advocates. We have the human rights convention framed on our walls … but now, we are supposed to adapt to an absolute minimum approach. We’re now at the edge of the European Convention. It’s a clear political signal, but we have to figure out what it means to us, this new focus on minimum levels and on return. (Richard, senior official at Swedish Migration Agency) own meals still entails. And, the asylum camps look more like detention camps now. This sends a signal that they are not welcome.
Volatility Distribution of the DJSTOXXE50 Index

In this paper using data from 1995-2005 on 5-minute intraday returns, we construct a model free estimate of the daily realized volatility for the DJSTOXXE50 index. We compute the unconditional volatility distribution of the DJSTOXXE50 index by a nonparametric kernel estimation method. Our results indicate that the unconditional volatility distribution of the DJSTOXXE50 returns are leptokurtic and highly skewed to the right. The logarithmic standard deviations seem to be approximately Gaussian. Our results are inline with previous research for individual DJIA equity return volatility and for Japanese index, Nikkei 225
Antimony(III) tellurium(IV) chloride trioxide SbTeO3Cl: synthesis and ab initio structure determination from X-ray and neutron powder diffraction data

The mixed chloride oxide SbTeO3Cl has been prepared in polycrystalline form by solvolysis reaction from SbCl3 and TeCl4. The X-ray and neutron powder diffraction patterns were indexed in an orthorhombic unit cell; the structure was partially solved in the space group Pnma from the X-ray data, and completed and refined from neutron data. The crystal consists of strongly covalent [SbTeO3]+ layers, perpendicular to the a axis, corrugated as a consequence of the electrostatic repulsion of the lone pairs of SbIII and TeIV. Both semimetals are three-fold co-ordinated to oxygens in pyramidal configuration. The layers are held together by discrete Cl– anions. This is one of the few examples of a positively charged two-dimensional network, very uncommon in the crystal chemistry of inorganic oxo compounds.
