Recently, a new hyperchaos generator, obtained by controlling a three-dimensional autonomous chaotic system — Chen's system — with a periodic driving signal, has been found. In this letter, we formulate and study the hyperchaotic behaviors in the corresponding fractional-order hyperchaotic Chen's system. Through numerical simulations, we found that hyperchaos exists in the fractional-order hyperchaotic Chen's system with order less than 4. The lowest order we found to have hyperchaos in this system is 3.4. Finally, we study the synchronization problem of two fractional-order hyperchaotic Chen's systems.

In this paper, impulsive control of nonlinear systems and its application to Chen's chaotic system are considered. A new impulsive control method for chaos suppression, using Chen's system as an example, is developed. Some new general criteria for exponential stability and asymptotical stability of nonlinear impulsive systems are established and, particularly, some simple conditions sufficient for driving the chaotic state of Chen's system to its zero equilibrium are presented.

In this paper, the complex dynamical behaviors of the chaotic trajectories of Chen's system are analyzed in detail, with its precise bound derived for the first time. In particular, it is rigorously proved that all nontrivial trajectories of the system always travel alternatively through two specific Poincaré projections for infinitely many times. The results provide an insightful understanding of the complex topological structure of Chen's chaotic attractor.

Anticontrol of chaos by making a nonchaotic system chaotic has led to the discovery of some new chaotic systems, particularly the continuous-time three-dimensional autonomous Chen's equation with only two quadratic terms. This paper further investigates some basic dynamical properties and various bifurcations of Chen's equation, thereby revealing its different features from some other chaotic models such as its origin, the Lorenz system.

Annotation:

By applying the undetermined coefficient method, this paper finds homoclinic and heteroclinic orbits in the Chen system. It analytically demonstrates that the Chen system has one heteroclinic orbit of Ši'lnikov type that connects two nontrivial singular points. The Ši'lnikov criterion guarantees that the Chen system has Smale horseshoes and the horseshoe chaos. In addition, there also exists one homoclinic orbit joined to the origin. The uniform convergence of the series expansions of these two types of orbits are proved in this paper. It is shown that the heteroclinic and homoclinic orbits together determine the geometric structure of Chen's attractor.

Two training systems(open lyre and Kniffin) with two planting densities(3.3 m × 1.5-1.1 m and 1.8 m × 1.5-1.1 m, R × V, respectively) were evaluated for their effects on growth, yield, and fruit quality of fourteen grapes grafted to SO4. Cane pruning weights of vines grafted to SO4 rootstocks averaged 268.1 kg/10a. Chenin Blanc, Cabernet Sauvignon, and Clairette grapes had greater cane pruning weights. Pruning weights of vines trained to the Kniffin system with 1.8 m × 1.1 m spacing were greater. Fruit yields of young vines averaged 438.6 kg/10a, and SV 5276, Carignane, and Ugni Blanc grapes were more productive while Riesling, Grenache, Chenin Blanc, Muscat de Frontignan grapes were less productive. Yields of grapevines trained to the Kniffin system with 1.8 m × 1.1 m spacing were more productive. Fruit quality was less affected by training system and planting density, but significant varietal differences were recognized.

An impulsive T–S fuzzy model is presented in this paper. The stability of impulsive controlled T–S fuzzy system has been analyzed theoretically. The proposed impulsive control scheme seems to have a simple control structure and may need less control energy than the normal continuous ones for the stabilization of T–S fuzzy system. Some typical chaotic systems, such as Chua's circuit, Lorenz system and Chen's chaotic system, are considered as illustrations to demonstrate the effectiveness of the proposed control scheme.

Annotation:

Subcooled boiling is the most effective form of heat exchange in the water jacket of the cylinder head. Chen's model is the most widely used correlation for predicting boiling heat transfer, but the selection of the correlation for the nucleate boiling is controversial. The work of this paper is to simulate the heat transfer process in the water jacket of the cylinder head with a horizontal rectangular channel that is heated on one side. Using the coolant flow velocity, inlet temperature and system pressure as variables, the heat flux and heat transfer coefficient were obtained. The results show that the increase of the coolant flow velocity can effectively promote the convection heat transfer, and the change of inlet temperature and system pressure will affect the occurrence of nucleate boiling. However, the Chen?s model predictions doesn?t fit well with the experimental data. Four nucleate boiling correlations were selected to replace Chen's model nucleate boiling correlation. The correlation proposed by Pioro coincides best with the experimental data. The mean error after correction is 18.2%.

Annotation:

Hajdu-Cheney syndrome (HCS) is a rare multi-system disease with autosomal dominant inheritance and skeletal involvement, resulting mostly in craniofacial dysmorphy with mid-face hypoplasia, dental anomalies, short stature, scoliosis, shortening of the digits and nail beds, acro-osteolysis and osteoporosis. We report the progression of clinical and radiographic findings in five patients with Hajdu-Cheney syndrome from two families. A custom capture array designed to capture exons and adjacent intron sequences of 230 selected genes were used for molecular analyses, and the pathogenic variants identified were confirmed by PCR and Sanger sequencing. In both families we observed age-dependent changes in the disease, with a progression of pain in older patients, a shortening of digits and nail beds on both the hands and feet, kyphoscoliosis and the persistence of Wormian bones in lambdoid sutures. Molecular analyses performed in two patients revealed that they are heterozygotes for a c.6255T>A (p.Cys2085*) variant in the NOTCH2 gene, resulting in a premature stop-codon. Bone mineral density (Z-score < –2) did not improved in a girl treated with calcium and vitamin D supplementation during childhood and bisphosphonate during adolescence. Hajdu-Cheney syndrome is a slowly progressive disease with a frequently unfavourable prognosis in elderly patients, especially for the development of dental anomalies, osteoporosis and the progression of skeletal complications requiring orthopedic surgeries.

Annotation:

A Bursaphelenchus species was isolated from a Japanese native wood-boring weevil, Niphades variegatus, and dead Pinaceae trees. The nematode is associated with the weevils as dauer (dispersal third stage) juveniles and the dauers enter the weevil tracheal system forming an abnormal expansion on the weevil trachea (atrium). Thus, the nematode is hypothesised to be an amensal/phoretic associate of the weevil because the abnormal expansion appeared to inhibit weevil respiration. The propagative stages of the nematode are associated with dead trees (wood and bark materials) and are thought to feed there on naturally propagated fungi. Morphologically, the new species is considered an undescribed species close to B. antoniae, B. chengi and B. hylobianum. Within these four species, the new species, which is described herein as B. niphades n. sp., is closest to B. chengi, i.e., the typological character of these two species are almost identical to each other and is distinguished by some minor characters (structure of the male P4 genital papillae and spicule length). The molecular phylogenetic analysis supported the morphological observations. Bursaphelenchus niphades n. sp. formed a well supported subclade with the four species and is intermediate between B. hylobianum and B. chengi; however, it is distinguished by the molecular sequences of some ribosomal RNA genes. Because three of these four species are associated with weevil species, the subclade is considered a ‘weevil-associated’ species group.

The permanence of a single-species population discrete model with feedback control is considered. We found that if we use the method of comparison theorem, then the additional condition, to some extent, is necessary. But for the system itself, this condition may not be necessary. Here, we use new methods instead of the comparison theorem to get the permanence of the system in consideration; the additional condition in Chen's paper (2007) is deleted.

Studied in this paper is the control problem of hyperchaotic systems. By combining Takagi–Sugeno (T–S) fuzzy model with parallel distributed compensation design technique, we propose a delay-dependent control criterion via pure delayed state feedback. Because the result is expressed in terms of linear matrix inequalities (LMIs), it is quite convenient to check in practice. Based on this criterion, a procedure is provided for designing fuzzy controller for such systems. This method is a universal one for controlling continuous hyperchaotic systems. As illustrated by its application to hyperchaotic Chen's system, the controller design is quite effective.

In this paper, a new adaptive switching control scheme is presented to solve control and synchronization problems. Based on Lyapunov stability theory, an adaptive control law is applied to globally stabilize chaotic systems and achieve states synchronization of two chaotic systems whose dynamics are subjected to the system disturbances and/or some unknown parameters. Simulation examples, the chaotic Chen's system and Chua's circuit, are given to show the feasibility and effectiveness of the proposed theory and method.

The current study was carried out to evaluate prevalence of endoparasites in freshwater fishes of Chenab River. The fish samples were collected from Chenab River during November 2014 to March 2015. In total, 285 fishes were examined for parasites, of which 75 fishes (26.1% of the total sample) were infected with parasites. Among the species, prevalence of infection was maximum in Rita rita (60%) and in Labeo rohita (37.5%). The minimum prevalence was, however, recorded in Oreochromis aureus (16.7%) and no parasite was found in Mastacembatus armatus. Among the organs, highest prevalence of endoparasites was observed in the intestine (43%) and gall bladder (33.2%). The prevalence of nematode and trematode was found higher (29 and 21%, respectively) in all fishes. It was revealed that the diversity of endoparasites in freshwater fishes is high. Since the use of fish as a ready source of food is increasing, therefore, the overall health status of fish in a system is becoming more valuable.Bangladesh J. Zool. 46(1): 53-61, 2018

Impulsive synchronization of chaotic systems is an attractive topic and a number of interesting results have been obtained in recent years. However, all of these results on impulsive synchronization need to employ full states of the system to achieve the desired objectives. In this paper, impulsive synchronization that needs only part of system states is studied for a class of nonlinear system. Typical chaotic systems, such as Lorenz system, Chen's system, and a 4D hyperchaotic system, are taken as examples. A new scheme is proposed to select the impulsive intervals. After some theoretical analysis, simulation results show the effectiveness of the proposed synchronization scheme.

Recently, control and synchronization of fractional chaotic systems have increasingly attracted much attention in the fractional control community. In this paper we introduce a novel class of fractional chaotic systems in the pseudo state space and propose an adaptive sliding mode control scheme to stabilize the chaotic systems in the presence of uncertainties and external disturbances whose bounds are unknown. To verify the effectiveness of the proposed adaptive sliding mode control technique, numerical simulations of control design of fractional Lorenz's system and Chen's system are presented.

Annotation:

In this paper, a methodology to design a system that robustly synchronizes a master chaotic system from a sampled driving signal is developed. The method is based on the fuzzy Takagi–Sugeno representation of chaotic systems, from which a continuous-time fuzzy observer is designed as the solution of an LMI minimization problem such that the error dynamics have H∞disturbance attenuation performance. Then, from the dual-system approach, the fuzzy observer is digitally redesigned such that the performance is maintained for the sampled master system. The effectiveness of the proposed synchronization methodology is finally illustrated via numerical simulations of the chaotic Chen's system.

The problem of hybrid chaos synchronization is investigated, where a digital response subsystem is designed to synchronize with an analog drive subsystem. The approach taken is a new prediction-based digital redesign for a continuous-time observer embedded in the response via an optimal linearization approach of the nonlinear chaotic systems. Three typical but topologically quite different chaotic systems, Chua's circuit, Duffing oscillator, and Chen's system, are simulated thereby validating the novel design proposed in this paper.

From distant past to present day, the Southern region has been playing an important role in national defense and foreign affairs, with great potential to create a breakthrough for the socioeconomic development of Vietnam. However, due to historical conditions and geographical location, political instabilities were frequently seen in the Southern region under the rule of the Nguyen lords and the early Nguyen Dynasty (early 19th century), especially the instability of the relationship between three feudal countries: Dai Viet (Vietnam), Chenla (Cambodia) and Siam (Thailand) from the 17th century to the first half of the 19th century. In its Southern defense strategy to prevent Siamese invasions and maintain its position as the "protector" of Chenla as well as to develop the new land, the Nguyen Dynasty focused on building border defense formation on land and sea in the South, with the defense system on the border area of Chau Doc, Ha Tien and the Southwestern sea in the Gulf of Thailand as the focus. The Nguyen Dynasty's proper implementation of policies in the border and sea areas had brought great effects and contributed to the strong protection of Dai Viet's sovereignty over the Southern land.

A fuzzy-neural fluctuation smoothing rule is proposed in this study to improve the performance of scheduling jobs with various priorities in a semiconductor manufacturing factory. The fuzzy-neural fluctuation smoothing rule is modified from the well-known fluctuation smoothing rule by improving the accuracy of estimating the remaining cycle time of a job, which is done by applying Chen's fuzzy-neural approach with multiple buckets. To evaluate the effectiveness of the proposed methodology, production simulation is also applied in this study. According to experimental results, incorporating a more accurate remaining cycle time estimation mechanism did improve the scheduling performance especially in reducing the average cycle times. Besides, the fuzzy-neural fluctuation smoothing rule was also shown to be a Pareto optimal solution for scheduling jobs with various priorities in a semiconductor manufacturing factory.

Citri Reticulatae Pericarpium (CRP), also known as Chenpi in Chinese, is the dry mature peel of Citrus reticulata Blanco or its cultivated varieties. CRP as the health-care food and dietary supplement has been widely used in various diseases. However, the potential pharmacological mechanisms of CRP to predict and treat various diseases have not yet been fully elucidated. A systems pharmacology-based approach is developed by integrating absorption, distribution, metabolism, and excretion screening, multiple target fishing, network pharmacology, as well as pathway analysis to comprehensively dissect the potential mechanism of CRP for therapy of various diseases. The results showed that 39 bioactive components and 121 potential protein targets were identified from CRP. The 121 targets are closely related to various diseases of the cardiovascular system, respiratory system, gastrointestinal system, etc. These targets are further mapped to compound-target, target-disease, and target-pathway networks to clarify the therapeutic mechanism of CRP at the system level. The current study sheds light on a promising way for promoting the discovery of new botanical drugs.

The present study modeled the relationship between the Stroop and the neutral naming times to investigate the mechanism underlying the Stroop interference effect. 95 subjects took six alternative versions of the Stroop task and the naming times in the Stroop and neutral conditions were each averaged across the tasks to arrive at a more general measure of the Stroop and neutral naming times. Regression analysis of these general measures indicated a linear function with a small and nonsignificant intercept and a slope significantly greater than one. This finding is consistent with Chen's 1996 results and supports the hypothesis that the mechanism underlying the Stroop interference is interactive or multiplicative rather than stage-like or additive and that a ratio of Stroop over neutral naming times was psychologically a more appropriate measure.

Salinity is the most important factor of consideration for the water management policies. The water availability from the rootzone reduced with the increase in the soil salinity due to the increase in the osmatic pressure. In Pakistan, salinity is the major threat to the agriculture land due to the tradition practices of irrigation and extensive utilization of the groundwater to meet the cope the irrigation water requirement of high intensity cropping system. The salinity impact is spatially variable on the canal commands area of the irrigation system. There is dire need to map the spatially distributed soil salinity with the high resolution. Landsat satellite imagery provides an opportunity to have 30m pixel information in seven spectral wavelength ranges. In this study, the soil salinity mapping was performed using pixel information on visible and infrared bands for 2015. These bands were also used to infer Normalized Difference Vegetation Index (NDVI). The raw digital numbers were converted into soil salinity information. The accuracy assessment was carried out using ground trothing information obtained using the error matrix method. Four major classes of non-saline, marginal saline, moderate saline and strongly, saline area was mapped. The overall accuracy of the classified map was found 83%. These maps can be helpful to delineate hot spots with severe problem of soil salinity in order to prepare reciprocate measures for improvement.

In this article, we use a variant of a recently introduced algebraic state estimation method obtained from a fast output signal time derivatives computation process. The fast time derivatives calculations are entirely based on the consequences of using the "algebraic approach" in linear systems description (basically, module theory and non-commutative algebra). Here, we demonstrate, through computer simulations, the effectiveness of the proposed algebraic approach in the accurate and fast (i.e. nonasymptotic) estimation of the chaotic states in some of the most popular chaotic systems. The proposed state estimation method can then be used in a coding–decoding process of a secret message transmission using the message-modulated chaotic system states and the reliable transmission of the chaotic system observable output. Simulation examples, using Chen's chaotic system and the Rossler system, demonstrate the important features of the proposed fast state estimation method in the accurate extraction of a chaotically encrypted messages. In our simulation results, the proposed approach is shown to be quite robust with respect to (computer generated) transmission noise perturbations. We also propose a way to evade computational singularities associated with the local lack of observability of certain chaotic system outputs and still carry out the encrypting and decoding of secret messages in a reliable manner.

This research looks at the Afghanistan War from the Soviet invasion of 1979 until the withdrawal of North Atlantic Treaty Organization in 2014 through films chosen. This research demonstrates how the Soviets, supported by the USA and the Muslim world, operated on misconceptions during an insurrectional conflict against the Mujahedin. After September 11, the Bush-Cheney administration invaded Afghanistan, restricting the informative role of the corporate media system. According to Kellner, this action triggered a creative revolution in American cinema. Turning to the production of documentaries, directors abandoned large-scale productions, preferring highly dramatically charged narratives of real soldiers and real action. The Afghan war, a fragmented, relentless, and unremitting struggle, is portrayed in 9th Company (Rus), Restrepo (USA). And Armadillo (Denmark); and Kajaki (UK), films that narrates the conflict from the NATO perspective, can not be won.
