H∞ Synchronization for Fuzzy Markov Jump Chaotic Systems with Piecewise-Constant Transition Probabilities Subject to PDT Switching Rule

This paper investigates the non-fragile H∞ synchronization issue for a class of discrete-time T-S fuzzy Markov jump systems. With regard to the T-S fuzzy model, a novel processing method based on matrix transformation is introduced to deal with the double summation inequality containing fuzzy weighting functions, which may be beneficial to obtain conditions with less conservatism. In view of the fact that the uncertainties may occur randomly in the execution of actuator, a non-fragile controller design scheme is presented by virtue of the Bernoulli distributed white sequence. The main novelty of this paper lies in that the transition probabilities of Markov chain are considered to be piecewise time-varying, and whose variation characteristics are described by the persistent dwell-time switching regularity. Then, based on Lyapunov stability theory, it is concluded that the resulting synchronization error system is mean-square exponentially stable with a prescribed H∞ performance in the presence of actuator gain variations. Finally, an illustrative example about Lorenz chaotic systems is provided to show the effectiveness of the established results.
Prognostic significance of risk factors for thyrotoxicosis development in radioiodine therapy

Background. Graves’ disease (GD) is a systemic autoimmune disease that develops as a result of the production of antibodies to the thyroid-stimulating hormone receptor, which is clinically manifested by diffuse structural changes in the thyroid gland with the development of thyrotoxicosis syndrome, and also combined with extrathyroid manifestations. The purpose of the study was to identify Graves’ disease recurrence risk factors in women received radioiodine therapy. Materials and methods. 93 women of reproductive age who received radioiodine therapy (RIT) were under obsewrvation. We analyzed the results of the questionnaire and assessed the thyrotoxicosis recurrence risk factors with performed retrospective and prospective analysis of clinical and medical history indicators. Patient’s average age was 36.9 ± 7.1 years. The control group included 35 healthy women aged 33.5 ± 7.6 years. Thyroid stimulating hormone (TSH), free triiodothyonine (fT3) and free thyroxine (fT4) and thyroperoxidase antibodies (TPOAb) levels determined by the immunochemiluminescent method. Results. In order to evaluate the quality of a prognostic model of the thyrotoxicosis recurrence we calculated all risk factors parameters of the AUC. The most significant risk factors for the development of thyrotoxicosis recurrence after RTI with a high relative risk and etiological fraction were age over 30 years (RR = 7.59; EF = 8.82 %), thyroid volume ≥ 30 cm3 (RR = 6.84; EF = 85.38 %), treatment duration ≥ 2 years (RR = 6.37; EF = 84.30 %), patient compliance (RR = 6.19; EF = 83.84 %), RIT multiplicity (RR = 5.74; EF = 82.58 %) and a dose of RIT 300 MBq (RR = 5.41; EF = 81.52 %). Conclusions. It was revealed that the age is older than 30 years (AUC — 0.88), thyroid volume ≥ 30 cm3 (AUC — 0.86), treatment duration ≥ 2 years (AUC – 0.86), patient compliance (AUC — 0.85), RIT multiplicity (AUC — 0.85) and the dose of RIT (AUC — 0.82) have excellent predictive power.
New insights into the environmental factors controlling the circumpolar ground thermal regime

The thermal state of permafrost affects Earth surface systems and human activity in the Arctic and has implications to global climate. Improved understanding of the local-scale variability in the circumpolar ground thermal regime is required 10 to account for its sensitivity to changing climatic and geoecological conditions. Here, we statistically related circumpolar observations of mean annual ground temperature (MAGT) and active-layer thickness (ALT) to high-resolution (~1 km) geospatial data of climatic and local environmental conditions. The aim was to characterize the relative importance of key environmental factors and the magnitude and direction of their effects in predicting the circumpolar ground thermal regime at 1-km scale. The multivariate models fitted well to MAGT and ALT observations with average R values being ~0.94 and 0.78, 15 respectively. Corresponding predictive performances in terms of root mean square error were ~1.31 °C and 87 cm. Freezing air temperatures was the main factor controlling MAGT in permafrost conditions while thawing temperatures dominated when permafrost was not present. ALT was most strongly related to solar radiation and precipitation with important non-linear influences from soil properties. Our findings suggest that in addition to climatic factors, local-scale variability in soil and topography need to be considered in order to realistically assess the current and future ground thermal regimes across the 20 circumpolar region.
PRELIMINARY STUDY ON PRODUCTION OF MONOACYLGLYCEROL AND DIACYLGLYCEROL OF VIRGIN COCONUT OIL VIA ENZYMATIC GLYCEROLYSIS USING LIPASE Candida antarctica ( Novozyme 435 )

Virgin coconut oil (VCO) consists mainly of saturated medium chain fatty acids which are 48.8% lauric acid (C12:0) and 20.0% myristic acid (C14:0). Both medium chain fatty acids are essential in increasing metabolism and possess antibacterial properties. These fatty acids of VCO are in the form of triacylglycerols (TAGs). Hence, VCO has to be converted into a simpler form such as monoand diacylglycerols (MAGs and DAGs) in order to increase its antibacterial functionality in metabolism. In this paper, VCO was chemically modified via enzymatic glycerolysis reaction conducted at a molar ratio of 1:1 (VCO:glycerol) and catalysed by lipase enzyme, Candida antarctica (Novozyme 435). The reaction was carried out in an incubator shaker at 50 °C and 250 rpm of reaction speed. Reaction parameters were reaction time (24 and 48 hours) and enzyme concentrations (3, 5 and 10%). The product comprises of 3.3% MAG, 3.6% DAG and 93.1% TAG has been obtained by preliminary optimum reaction condition at temperature of 50 °C with 5 %wt of enzyme concentration at 24 hours of reaction time. Chemical analysis techniques used were thin layer chromatography (TLC), fourier transformation infrared (FT-IR) spectroscopy and gas chromatography (GC). Products are potentially to be used as food emulsifier, pharmaceutical binders, antibacterial products as well as food additives.
Maturation in Larch1 1. Effect of Age on Shoot Growth, Foliar Characteristics, and DNA Methylation

The time course of maturation in eastern larch (Larix laricina [Du Roil K. Koch) was examined by grafting scions from trees of different ages onto 2-year-old root stock and following scion development for several years. Height, diameter, foliar chlorophyll content, and rooting ability of scion-derived cuttings all varied linearly as a function of log10 age. Chlorophyll content (milligrams per gram of dry weight) increased while height, diameter, and ability to root decreased with age (P < 0.01). The tendency toward orthotropic growth and branch formation per centimeter of main stem decreased abruptly between age 1 and 5 years (P < 0.01). Total chlorophyll content of both long and short shoot foliage increased by 30 to 50% with increasing age, but the chlorophyll a/b ratio did not change. Also, juvenile long shoot needles were significantly longer than mature (P < 0.01). Surprisingly, the juvenile scions produced more total strobili over two successive years, but the mature scions produced a significantly higher proportion of male strobili (P < 0.001 year 1; P < 0.02 year 2). The age-related changes in foliar traits were not associated with changes in DNA methylation between juvenile and mature scions. Using HPLC, we found that 20% of foliar DNA cytosine residues were methylated in both scion types.
The Spatiotemporal Dynamics of Soybean and Cattle Production in Brazil

The expansion of agricultural frontiers in Brazil has caused substantial changes in land use and land cover. This research aims to analyze the space-time dynamics of soybeans and cattle production in the Brazilian territory during the period 1991–2015. The spatial analysis adopted the following procedures: (a) The change vector from the annual calculation of the midpoint of production; (b) mapping of the growth and acceleration rates of the two productions, and (c) mapping of the correlation between the time series of soybean and cattle. The results showed high rates of growth and acceleration for soy production in the South, Central-West and Matopiba regions. The growth acceleration rate identified the long-term deviations that characterized the effective soybean and cattle expansion areas. The results demonstrated the effects of Brazil’s soy moratorium contained soybean expansion into the Amazon region. However, as a side effect, the soybean production replaced cattle production in the savanna region, which in turn, migrated to the Amazon rainforest. Therefore, the present study highlights the importance of public policies that comprehensively understand the spatial-temporal dynamics of Brazilian agriculture to promote sustainable land-use practices.
Differential Roles of FcrRII and FcrRIII in Immune Complex Stimulation of Human Neutrophils*

Insoluble immune complexes (IIC) stimulate human neutrophils through Fcr receptors. Freshly isolated human neutrophils express two FcR subclasses, FcRII and FcRIII. We explored the role of FcRII and FcRIII in this activation process by selectively binding each FcR subclass with the Fab fragments of the respective anti-FcR monoclonal antibodies (MFab) before exposure to IIC. Correlation among liganded FcR subclass, IIC binding, and ensuant IIC stimulation was achieved with multiparameter flow cytometry. We utilized rhodamine-labeled anti-FcRIII and fluorescein-labeled IIC to study binding and observed the change in [Ca2+Ii n the same cell with a Ca2+ indicator, Indo-1. Treatment with either anti-FcRII (IV.3) or anti-FcRIII (3G8) MFab decreased both the fraction of cells exhibiting a Ca2+ transient and the magnitude of that transient, although only anti-FcRIII but not anti-FcRII significantly inhibited the subsequent IIC binding. In addition, cells treated with anti-FcRII and then stimulated with IIC exhibited a decrease in both the intracellular Ca2+ transient and the later Ca” influx, whereas anti-FcRIII totally abolished the mobilization of intracellular Ca2+ without affecting the Ca2+ influx. Treatment with either anti-FcR MFab decreased the IIC-stimulated transmembrane potential change, oxidative burst, and elastase release. These studies indicate that freshly isolated neutrophils’ Fc receptor subclasses have unique roles in the IIC-initiated stimulation and that full activation can only be achieved when both FcR subclasses are available.

JUSTIFICATION OF EFFICIENCY OF PLAIN SHAPED HEAT EXCHANGE SURFACES TO INCREASE THE COMPACTNESS OF POWER PLANTS

The studies were out for four types of with ratios 2; 3.4; 5.0. The Substantiation of using non-circular plain shaped surfaces to increase the compactness of power plants is presented. The criterion of thermohydraulic compactness is justified, which takes into account the layout and arrangement of heat transfer elements and their thermohydraulic efficiency. To simulate heat movement and transfer processes in elements of power plants, the computational fluid dynamics method is used. Verification is carried out with available literature data, the discrepancy of results does not exceed 2.4 %. For single elliptical and plane-oval shapes, there is a local maximum of efficiency, achieved at the axis ratio of 2.5 for elliptical and 2.75 for plane-oval. Studies of the change of the heat transfer coefficient in the tube bank rows are carried out. For the elliptical tube bank, heat transfer is stabilized from the fifth row. Heat transfer surfaces of circular, elliptical and plane-oval tubes with different combinations of geometric characteristics are considered. It is found that on the basis of elliptical tubes it is possible to reduce the volume of the heat transfer surface and increase the compactness of the entire power plant by 18.3 % compared to circular tubes and 2.4 % compared to flat-oval ones. Dimensionless indices of mass, volume, functional efficiency and service life of the heat exchanger are substantiated, allowing them to be compared as part of various power plants. It is advisable to continue studies of the features of heat transfer processes in close, with the relative longitudinal and transverse pitch ratio less than 1.5, banks of elliptical tubes with an axis ratio of 2.5

Improvement in the anti-wear (AW) and extreme pressure (EP) ability of chemically modified palm oil (CMPO) by adding nanoparticles was experimentally evaluated. Nanolubricants were synthesized by adding 1 wt% copper(II) oxide (CuO) and 1 wt% molybdenum disulfide (MoS2) nanoparticles to CMPO. The AW/EP properties of the formulations were evaluated by four-ball and sliding wear tests. Wear surfaces were analyzed by scanning electron microscopy, along with energy-dispersive X-ray and micro-Raman scattering spectroscopy. The MoS2 nanoparticles exhibited better AW/EP properties than did the CuO nanoparticles. The addition of 1 wt% oleic acid as a surfactant facilitated the reduction of agglomerates.
The Effects of Applications Humic Acids on Macronutrient, Micronutrient, Heavy Metal and Soil Properties

Heavy metal, Humic acids, Marigold, Soil. Abstract: This study was conducted on the YYU campus area as a field survey, according to the randomized block experimental design carried out in three replicated. The yellow and orange marigold species with humic acids (HA0;0 kg HA da-1, HA1;10 kg HA da-1, HA2;20 kg HA da-1, HA3;40 kg HA da-1) were used. At the end of the experiment, the soil samples taken from the field of study were analyzed organic matter, soil reactions, total salt content, lime content, nitrogen, phosphorus, potassium, calcium, magnesium, natrium, iron, manganese, zinc, copper, cadmium, nickel and lead contents. The increased humic acid applications have influenced pH (P<0.01), lime (P<0.01), organic matter (P<0.05) with phosphorus (P<0.01), iron (P<0.05), zinc (P<0.05) and nickel (P<0.01) contents. The effect variety (V) has been determined on the available of soil iron (P<0.01), zinc (P<0.01), cadmium (P<0.01), nickel (P<0.01), and lead (P<0.01) contents. The interaction of only affected the nickel (P<0.01) and zinc (P<0.01) contents. As a result, humic acid applications have an important and positive effect on many properties of soil.
CONTRACTING AND ERUPTING COMPONENTS OF SIGMOIDAL ACTIVE REGIONS

It has recently been noted that solar eruptions can be associated with the contraction of coronal loops that are not involved in magnetic reconnection processes. In this paper, we investigate five coronal eruptions originating from four sigmoidal active regions, using high-cadence, high-resolution narrowband EUV images obtained by the Solar Dynamic Observatory (SDO). The magnitudes of the flares associated with the eruptions range from GOES class B to class X. Owing to the high-sensitivity and broad temperature coverage of the Atmospheric Imaging Assembly (AIA) on board SDO, we are able to identify both the contracting and erupting components of the eruptions: the former is observed in cold AIA channels as the contracting coronal loops overlying the elbows of the sigmoid, and the latter is preferentially observed in warm/hot AIA channels as an expanding bubble originating from the center of the sigmoid. The initiation of eruption always precedes the contraction, and in the energetically mild events (B- and C-flares), it also precedes the increase in GOES soft X-ray fluxes. In the more energetic events, the eruption is simultaneous with the impulsive phase of the nonthermal hard X-ray emission. These observations confirm that loop contraction is an integrated process in eruptions with partially opened arcades. The consequence of contraction is a new equilibrium with reduced magnetic energy, as the contracting loops never regain their original positions. The contracting process is a direct consequence of flare energy release, as evidenced by the strong correlation of the maximal contracting speed, and strong anti-correlation of the time delay of contraction relative to expansion, with the peak soft X-ray flux. This is also implied by the relationship between contraction and expansion, i.e., their timing and speed.

KINETIC EVIDENCE FOR A CATALYTICALLY ESSENTIAL CONFORMATIONAL CHANGE IN THE TERNARY COMPLEX*

We carried out a steady state kinetic analysis of the bacteriophage T4 DNA-[N-adenine]methyltransferase (T4 Dam) mediated methyl group transfer reaction from S-adenosyl-L-methionine (AdoMet) to Ade in the palindromic recognition sequence, GATC, of a 20-mer oligonucleotide duplex. Product inhibition patterns were consistent with a steady state-ordered bi-bi mechanism in which the order of substrate binding and product (methylated DNA, DNA and S-adenosyl-L-homocysteine, AdoHcy) release was AdoMet2DNA2DNA1AdoHcy1. A strong reduction in the rate of methylation was observed at high concentrations of the substrate 20-mer DNA duplex. In contrast, increasing substrate AdoMet concentration led to stimulation in the reaction rate with no evidence of saturation. We propose the following model. Free T4 Dam (initially in conformational form E) randomly interacts with substrates AdoMet and DNA to form a ternary T4 Dam-AdoMet-DNA complex in which T4 Dam has isomerized to conformational state F, which is specifically adapted for catalysis. After the chemical step of methyl group transfer from AdoMet to DNA, product DNA dissociates relatively rapidly (koff 1.7 s ) from the complex. In contrast, dissociation of product AdoHcy proceeds relatively slowly (koff 0.018 s ), indicating that its release is the rate-limiting step, consistent with kcat 0.015 s . After AdoHcy release, the enzyme remains in the F conformational form and is able to preferentially bind AdoMet (unlike form E, which randomly binds AdoMet and DNA), and the AdoMet-F binary complex then binds DNA to start another methylation cycle. We also propose an alternative pathway in which the release of AdoHcy is coordinated with the binding of AdoMet in a single concerted event, while T4 Dam remains in the isomerized form F. The resulting AdoMet-F binary complex then binds DNA, and another methylation reaction ensues. This route is preferred at high AdoMet concentrations.
INDONESIANS' PERSPECTIVE 控制打击腐败:印度尼西亚人的视角的治理模型

The purpose of this study is to propose an appropriate governance model to deal with corruption. This study reveals the indicators, from where and how corruption will be resisted. By using data governance and corruption control as well as the corruption perception index from WGI and TII in 2008-2018, this study proposed a quantitative approach to strengthen the results of the inference tests of the effect of good governance on the potential for corruption, confirming and expanding on work carried out with critical informants by Transparency International Indonesia (TII). The study found that, from the perspective of agency theory, the influence of governance on corruption has been proved, both in the context of the world and Indonesia. Good governance will make the trustee (agent) not arbitrarily follow their wishes through corruption to enrich themselves or other parties, but instead follow the mandate given by the principal (community). This study also shows, in the world context, that by adherence to ethical rules being followed by effective government, in stable political conditions, and public voices being heard, corruption can be eradicated. In the context of Indonesia, to suppress criminal acts of corruption, stable political conditions and guarantees for public votes must be done first, then effective government and compliance with regulations can follow.
DEVELOPMENT OF TiO 2 WHITE GLAZES FOR CERAMIC TILES : INFLUENCE OF FRIT MELTING AND GLAZE APPLICATION

Based on a previous work, the objective of this study was to determine the effect of melting and glazing conditions of an anatase glaze used to promote white opacity in ceramic tile coatings. An anatase frit (10wt% TiO2) was melted at 1,480°C and 1,530°C for 60min and 90min and quenched in water. Each frit was ground (30min) in eccentric mill with the addition of 10% kaolin, 0.2% sodium tripolyphosphate, 0.2% carboxymethylcellulose and 30% water, forming glaze slurries with 1.80g/cm3 density and viscosity of 100s in cup Ford n°4. The glazes were applied in layers of 0.4mm thickness over previously engobed tiles. The tiles were fired at 900°C, 1,000°C, 1,100°C and 1,190°C for 40min in a laboratory roller kiln. The colour of all the glazes was analyzed by spectrophotometry (400nm to 700nm) and the formed phases by x-ray diffraction (XRD CuKα) and scanning electronic microscopy (SEM). The results showed the glaze fired at 1,100°C obtained from the frit melted at 1,530°C for 90min formed a totally white glaze with great coating capacity. The results of scanning electron microscopy and X-ray diffraction revealed that the opacity is caused by tiny rutile crystals developed as function of melting and application temperature.
Infrared Astronomy: Star Formation

Judging from the poster that the Organizing Committee has selected to announce the celebration of Guido Munch Jubilee, one can easily conclude that the main characteristics of the process of star formation as emerged in recent years through the combined efforts of multiwavelengths studies of molecular clouds, were already known, here in Granada, several centuries ago to the masters who built and enriched the enigmatic palace of the Alhambra. As we can appreciate from a quick inspection of the picture, it is rather obvious to infer that stars are the byproduct of a quite complex series of phenomena, each connected to, and somewhat dependent on, the others. Also, stars do not form in isolation, but rather in clusters or associations, with a strong tendency for the largest ones, also the most massive ones, to sit in the middle of the distribution. Moreover, smaller and less massive stars outnumber their massive counterparts, apparently obeying a power-law distribution. Finally, but with the benefit of doubt, it appears that the idea that the whole process reflects an intrinsic fractal nature was also put forward at the time. With this background in mind, let us now turn to the new emerging aspects of the study of star formation.
