Penelitian ini bertujuan untuk mengetahui keakuratan kedua metode peramalan yaitu ARIMA dan GARCH serta untuk mengetahui metode manakah yang lebih akurat. Data yang digunakan adalah data harian saham DILD selama tahun 2014 yang berjumlah 242 hari perdagangan. ARIMA dan GARCH merupakan metode peramalan yang menggunakan data timeseries. Hasil penelitian menunjukkan bahwa data harga saham DILD selama setahun bersifat tidak stasioner, sehingga data perlu ditransformasikan dengan uji pembeda. Data yang sudah stasioner dapat digunakan dalam peramalan dengan metode ARIMA dan menghasilkan model terbaik yaitu ARIMA (1,1,1) yang memiliki unsur hetereroskedastisitas sehingga dapat dilakukan peramalan dengan metode GARCH dan memperoleh model terbaik yaitu GARCH (1,1) setelah melakukan uji coba dengan beberapa model lainnya. Peramalan dengan metode ARIMA (1,1,1) memiliki tingkat kesalahan absolute rata-rata sebesar 3,63% sedangkan peramalan dengan model GARCH  memiliki tingkat kesalahan absolut rata-rata sebesar (20,03)%. Dari hasil diatas, dapat disimpulkan bahwa metode ARIMA lebih akurat daripada metode GARCH dalam memprediksi harga saham perusahaan Intiland Development Tbk.  Kata Kunci  : Analisis Teknikal, Harga Saham DILD, ARIMA, GARCH

Authors:   Shadrinsk State Pedagogical University, Parfenova Svetlana Alekseevna , Chipinova Natalia Fedorovna ,   Shadrinsk State Pedagogical University
Published: May 2019

The paper discussed the economic development of the South Urals during the eighth and ninth five-year plans (1966-1975). By a case study of particular enterprises, the authors considered different forms of youth involvement in rationalization and invention (competitions, technical creativity contests) and their economic efficiency. The emphasis was placed on the reasons for the decrease in popularity of innovators movement. The research described the activities of integrated and cross-cutting teams based on a single work package, i.e. labor force participation rate helped evaluate the personal contribution of each team member to labor achievements and determine the wage rate. The paper revealed the reasons for failure to support this approach by skilled workers during the ninth five-year plan. The authors noted that mass media contributed significantly to the dissemination of information on the best innovators and accelerated technological progress in the industrial enterprises of the South Urals. The research highlighted the role of public organizations such as permanent production meetings, bureaus of economic analysis and labor regulation, innovators councils in attracting young people to production management.

Basic Emotion Recogniton using Automatic Facial Expression Analysis Software
Authors: Triyanti Vivi , Yassierli Yassierli , Iridiastadi Hardianto
Published: May 2019

Facial expression was proven to show a person's emotions, including 6 basic human emotions, namely happy, sad, surprise, disgusted, angry, and fear. Currently, the recognition of basic emotions is applied using the automatic facial expression analysis software. In fact, not all emotions are performed with the same expressions. This study aims to analyze whether the six basic human emotions can be recognized by software. Ten subjects were asked to spontaneously show the expressions of the six basic emotions sequentially. Subjects are not given instructions on how the standard expressions of each of the basic emotions are. The results show that only happy expressions can be consistently identified clearly by the software, while sad expressions are almost unrecognizable. On the other hand surprise expressions tend to be recognized as mixed emotions of surprise and happy. There are two emotions that are difficult to express by the subject, namely fear and anger. The subject interpretation of these two emotions varies widely and tends to be unrecognizable by software. The conclusion of this study is the way a person shows his emotions varies. Although there are some similarities in expression, it cannot be proven that all expressions of basic human emotions can be generalized. Further implication of this research needs further discussion.
Wiedemann-Steiner syndrome with a novel pathogenic variant in KMT2A: a case report
Authors: Ramirez Montaño Diana , Pachajoa Harry
Published: May 2019

Case Description:We report the case of a one-year-old girl who was diagnosed with Wiedemann-Steiner Syndrome based on the identification of a novel de novo frameshift mutation in the KMT2A gene by whole exome sequencing and supported by her clinical features.
Clinical Findings:KMT2A mutations cause Wiedemann-Steiner Syndrome, a very rare genetic disorder characterized by congenital hypertrichosis, short stature, intellectual disability, and distinct facial features.
Treatment and Outcome:Whole exome sequencing identified a novel frameshift variant: c. 4177dupA (p.Ile1393Asnfs * 14) in KMT2A; this change generates an alteration of the specific binding to non-methylated CpG motifs of the DNA to the protein. The genotype and phenotype of the patient were compared with those of earlier reported patients in the literature.
Clinical Relevance:In diseases with low frequency, it is necessary to establish a genotype-phenotype correlation that allows the establishment of therapeutic and follow-up goals. The phenotype comparation with other reported cases did not show differences attributable to sex or age among patients with Wiedemann-Steiner Syndrome. Whole exome sequencing allows identifying causality in conditions with high clinical and genetic heterogeneity like hypertrichosis.

Published: May 2019

The use of peptides in paper-based analytics is a highly appealing field, yet it suffers from severe limitations. This is mostly due to the loss of effective target recognition properties of this relatively small bioprobes upon nonspecific adsorption onto cellulose substrates. Here, we address this issue by introducing a simple polymer-based strategy to obtain clickable cellulosic surfaces, that we exploited for the chemoselective bioconjugation of peptide bioprobes. Our method largely outperformed standard adsorption-based immobilization strategy in a challenging, real-case immunoassay, namely the diagnostic discrimination of Zika+ individuals from healthy controls. Of note, the clickable polymeric coating not only allows efficient peptides bioconjugation, but it provides favorable anti-fouling properties to the cellulosic support. We envisage our strategy to broaden the repertoire of cellulosic materials manipulation and promote a renewed interest in peptide-based paper bioassays.
Pitfalls of the Martini Model
Authors: Alessandri Riccardo , Souza Paulo C. T. , Thallmair Sebastian , Melo Manuel N. , de Vries Alex H. , Marrink Siewert-Jan
Published: May 2019

The computational and conceptual simplifications realized by coarse-grain (CG) models make them an ubiquitous tool in the current computational modeling landscape. Building block based CG models, such as the Martini model, possess the key advantage of allowing for a broad range of applications without the need to reparametrize the force field each time. However, there are certain inherent limitations to this approach, which we investigate in detail in this work. We first study the consequences of the absence of specific cross Lennard-Jones parameters between different particle sizes. We show that this lack may lead to artificially high free energy barriers in dimerization profiles. We then look at the effect of deviating too far from the standard bonded parameters, both in terms of solute partitioning behavior and solvent properties. Moreover, we show that too weak bonded force constants entail the risk of artificially inducing clustering, which has to be taken into account when designing elastic network models for proteins. These results have implications for the current use of the Martini CG model and provide clear directions for the reparametrization of the Martini model. Moreover, our findings are generally relevant for the parametrization of any other building block based force field.
Quantifying Multiple Crystallite Orientations and Crystal Heterogeneities in Complex Thin Film Materials
Authors: Ogle Jonathan , Powell Daniel , Amerling Eric , Smilgies Detlef Matthias , Whittaker-Brooks Luisa
Published: May 2019

Thin film materials have become increasingly complex in morphological and structural design. When characterizing the structure of these films, a crucial field of study is the role that crystallite orientation plays in giving rise to unique electronic properties. It is therefore important to have a comparative tool for understanding differences in crystallite orientation within a thin film, and also the ability to compare the structural orientation between different thin films. Herein, we designed a new method dubbed the mosaicity factor (MF) to quantify crystallite orientation in thin films using grazing incidence wide-angle X-ray scattering (GIWAXS) patterns. This method for quantifying the orientation of thin films overcomes many limitations inherent in previous approaches such as noise sensitivity, the ability to compare orientation distributions along different axes, and the ability to quantify multiple crystallite orientations observed within the same Miller index. Following the presentation of MF, we proceed to discussing case studies to show the efficacy and range of application available for the use of MF. These studies show how using the MF approach yields quantitative orientation information for various materials assembled on a substrate.
Excited-State Proton Transfer: Molecules in a Hurry to Get Rid of Antiaromaticity
Authors: Wu Chia-Hua , Karas Lucas , Ottosson Henrik , Wu Judy
Published: May 2019

Baird’s rule explains why and when excited-state proton transfer (ESPT) reactions happen in organic compounds. Bifunctional compounds that are [4n+2] π-aromatic in the ground state, become [4n+2] π-antiaromatic in the first 1ππ* states, and proton transfer (eitherinter-or intra-molecularly) helps relieve excited-state antiaromaticity. Computed nucleus independent chemical shifts (NICS) for several ESPT examples (including excited-state intramolecular proton transfers (ESIPT), biprotonic transfers, dynamic catalyzed transfers, and proton relay transfers) document the important role of excited-state antiaromaticity. o-Salicylic acid undergoes ESPT only in the “antiaromatic” S1(1ππ*) state, but not in the “aromatic” S2(1ππ*) state. Stokes’ shifts of structurally-related compounds (e.g., derivatives of 2-(2-hydroxyphenyl)benzoxazole and hydrogen-bonded complexes of 2-aminopyridine with pro tic substrates) vary depending on the antiaromaticity of the photoinduced tautomers. Remarkably, Baird’s rule predicts the effect of light on hydrogen bond strengths; hydrogen bonds that enhance (and reduce) excited-state antiaromaticity in compounds become weakened (and strengthened) upon photoexcitation.

Mycobacterium abscessus (Mab) is a rapidly growing species of multidrug-resistant nontuberculous mycobacteria (NTM) that has emerged as a growing threat to individuals with cystic fibrosis, and other pre-existing chronic lung diseases. Mab pulmonary infections are difficult, or sometimes impossible, to treat and result in accelerated lung function decline and premature death. There is therefore an urgent need to develop novel antibiotics with improved efficacy. tRNA (m1G37) methyltransferase (TrmD) is a promising target for novel antibiotics. It is essential in Mab and other mycobacteria, improving reading frame maintenance on the ribosome to prevent frameshift errors. In this work a fragment-based approach was employed with the merging of two fragments bound to the active site, followed by structure-guided elaboration to design potent nanomolar inhibitors against Mab TrmD. Several of these compounds exhibit promising activity against mycobacterial species, including Mycobacterium tuberculosis and Mycobacterium leprae in addition to Mab, supporting the use of TrmD as a target for the development of antimycobacterial compounds.

Published: May 2019

Pd(II)–catalyzed C(sp3)–H olefination of native amide substrates was developed. To utilize the extremely weak-coordinating carbonyl-coordination of amides, an electron-deficient pyridinesulfonic acid ligand was designed. Structurally diverse amide substrates, including lactams, underwent olefination without the undesired cyclization. Olefination products were further diversified through synthetic transformations on the alkenyl moiety.

The objectives of this study are to evaluate the benefit of using Giemsa staining in endoscopic duodenal biopsies if it provides an appropriate tool to diagnose giardia parasite more accurate than the usual hematoxylin-eosin stain. Method: a retrospective study including fifty patients have been nominated with upper abdominal pain, attended gastrointestinal tract(GIT) consultation unit in medical City of Imam Al-Hussein-Karbala/ Iraq complaining from upper abdominal discomfort. They have been examined by esophagio- gastro duodenoscopy. All duodenal biopsies have also been collected from pathology excluding all celiac disease cases. All biopsies have paraffin and stained with hematoxylin and eosin looking for Giardia; in the following, the slides are stained with Giemsa stain following the manufacture-instruction. Results: 50patients (27 females and 23 males) have been examined depending on the hematoxylin and eosin staining, respectively, the diagnosis is non-specific chronic duodenitis with low MARSH score. Eleven patients from total fifty-two ones (21.15%) have shown positive symptoms for giardia cyst and trophozoite using the Giemsa stain. Conclusion: Giardia infection is difficult to be diagnosed with hematoxylin-eosin stain, especially with low infection. Consequently, Giemsa stain might be used to increase the efficacy of histopathological diagnosis of the parasite.
MEASUREMENT OF THE AMOUNT OF HEAT USING A DIATHERMIC COMBUSTION CALORIMETER WITHOUT PREHEATING OF THE CALORIMETER VESSEL IN A THERMOSTAT
Authors: Mashkinov Lev B.
Published: May 2019

A new method for measuring the amount of heat on the diathermic combustion calorimeter is presented. The method is based on filling the calorimeter vessel at room temperature and placing of the vessel in the measuring cell of the calorimeter (calorimeter is preliminary brought to a constant temperature) without preheating of the vessel in an isolated thermostat. Placing of a "cold" vessel into the cell and subsequent release of the reactive heat virtually balance each other, thus reducing the load on the temperature controller of the calorimeter. Note that not only pulse, but also the heat release of unrestricted continuance is recorded. Elimination of the preheating thermostat obviously simplifies the device design. The method has been patented.

The possibility of Pd (II), Pt (IV), and Rh (III) separation from chloride solutions by solvent extraction in rotating coiled columns (RCC) is demonstrated. The reagents most frequently used in extraction of platinum metals were selected as extractants: trioctylamine (TOA), methyltrialkylammonium chloride (MTAA), tributylphosphate (TBP), N, N, N',N'-tetra-re-octyldiglyTOlamide (TODGA). The completeness of extraction of the platinum group metals from individual and mixed hydrochloric acidic and chloride solutions was studied depending on the nature and concentration of the extractant, acidity of the test solutions and other factors. Optimal conditions for the quantitative extraction of metals from model hydrochloric acidic and chloride solutions and subsequent selective separation at the stripping stage are specified. A scheme of multistaged extraction separation of Pd (II), Pt (IV), and Rh (III) from chloride solutions using a 0.05 M solution of MTAA in toluene as a stationary phase in RCC is proposed. The scheme includes extraction of Pd (II) and Pt (IV) ions from a chloride solution (0, 1 M HCl + 30 g/liter NT) into the organic phase with simultaneous separation of Rh(III) remaining in the aqueous phase, and sequential stripping of Pd (II) and Pt (IV) from the organic phase with a 0.01 M solution of thiourea in 0.1 M HCl and a 1 M solution of thiourea in 0.5 M HCl, respectively. The scheme was tested in separation of the platinum group metals from the technological solution of a given composition. The degree of metal extraction with a 0.05 M MTAA solution in toluene and sequential stripping with thiourea solutions is 99.5% for Rh (III), 99.9% for Pd (II), and 97.4% for Pt (IV). The separated water fractions of rhodium and platinum after leaving the column did not contain impurities of other platinum metals whereas the water fraction of palladium contained 0.5% Pt.

Published: May 2019

The problems regarding arrangement and implementation of the intralaboratory quality control (ILC) of test results in testing laboratories (TL) are reviewed and summarized. The main goals of ILC directly aimed at minimization of the risks of getting unsatisfactory test results are considered along with the choice of the methods and types of control. The process and system approaches to organization and performance of the ILC are proposed with allowance for the risk assessment at the stages of planning, implementation, and monitoring of the ILC, which provide a control of all measurement techniques (MT) used in the laboratory, thus making the control procedure transparent to all the parties concerned. An effective way to describe the ILC starting with the stage of planning is recommended. The proposed "ILC Program" ensures the efficiency and effectiveness of the process to match the goals set for ILC: ensuring of the required accuracy (uncertainty) of current test results for the entire nomenclature of measurement techniques, maintaining the testing processes in a statistically controlled state, and, consequently, ensuring of the confidence of internal and external customers and supervisory organizations to the results of testing and activities of the TL as a whole thus proving the technical competence of the laboratory. We present the results of analysis of all ILC stages using the Shewhart-Deming — PDCA principle with a list of possible risks of obtaining unreliable results. Recommendations on the effective implementation of each stage of the process are given. Listed typical mistakes of ILC implementation can help the readers not only to avoid them, but also consider them as possible risks.

Published: May 2019

Lake Matano and Towuti are two of 15 lake priorities in Indonesia. For preservation purposes, a routine water quality monitoring from satellite is needed. In this study, 11 scenes of Landsat 8 data were processed to produce chlorophyll-a concentration as an indicator of water quality condition on these two lakes. The result showed that water quality in Lake Matano and Towuti were in low cholorphyll-a condition with chlorophyll-a concentration ranged from 0.000– 2.298 mg/m3, 0.000-2.236 mg/m3, respectively. The accuracy of estimated Chlorophyll-a in these two lakes were affected by an inaccurate of atmospheric corrected data. To improve the accuracy, a more accurate atmospheric correction algorithm for Landsat 8 was still required.
