Investigation of broken symmetry phases with long range ORDER in strongly correlated electron systems is among subjects that have always been of interest to condensed matter scientists. In this paper we tried to study the existence of the 120 degrees MAGNETIC SPIRAL ORDER, based on anisotropy in geometrically frustrated triangular lattices, using variational cluster approximation. We observed that by increasing the anisotropy in the system, the SPIRAL ORDER can be found for AWT IMAGE and for AWT IMAGE; however, it is limited by decreasing AWT IMAGE since antiferromagnetism is dominant for AWT IMAGE. Studying the Mott transition shows that a paraMAGNETIC insulating phase, called quantum spin liquid, happens in the neighborhood of the SPIRAL ORDERed phase.

SPIRAL wave is a particular spatiotemporal pattern, observed in a wide range of complex systems such as neuronal network. Appearance of these waves is related to the network structure as well as the dynamics of its blocks. In this paper, we propose a new modified Hindmarsh-Rose neuron model. The proposed model uses a hyperbolic memductance function as the monotonically differentiable MAGNETIC flux. An external electroMAGNETIC excitation is also considered in the model. Firstly, we study the dynamics of the proposed neuron model through bifurcation diagram and Lyapunov spectrum, in two cases of no excitation and periodic excitation. The bifurcation diagram shows the property of antimonotonicity, which has not been observed in the previous models. Then a square network is constructed and we investigate the spatiotemporal pattrens. By varying the parameters values, SPIRAL waves are observed in specific ranges. The formation of these waves depends on the interaction of all parameters simultaneously.

In this paper, recommended SPIRAL passive micromixer was designed and simulated. SPIRAL design has the potential to create and strengthen the centrifugal force and the secondary flow. A series of simulations were carried out to evaluate the effects of channel width, channel depth, the gap between loops, and flowrate on the micromixer performance. These features impact the contact area of the two fluids and ultimately lead to an increment in the quality of the mixture. In this study, for the flow rate of 25 μl/min and molecular diffusion coefficient of 1×10-10 m2/s, mixing efficiency of more than 90% is achieved after 30 (approximately one-third of the total channel length). Finally, the optimized design fabricated using proposed 3D printing method.

Non-radiative wireless power transfer systems based on MAGNETIC resonant coupling have received the attention of many researchers, due to their high efficiency over distances greater than the diameter of their coils and their mid-range of operations. In this article, the design and implementation of a 4-wireless power transmission system consisting of a power coil (drive loop), a transmitting coil (Tx coil), a receiving coil (Rx coil) and a load coil (load loop) is presented. Power is transmitted when the frequency of the E class amplifier is equal to the self-resonant frequency of the transceiver coils. The purpose of this paper is to achieve the highest efficiency without designing an additional impedance matching system. This condition is achieved by varying the coupling factor between the power coil (load) and the two resonators. The maximum efficiency is 93% at 15 cm and using this method results in efficiency improvements of 56. 3% and 35. 6% at the distances of 60 cm and 100 cm respectively, compared to the case of the coils being fixed.

Background and Aim: For certain surgical procedures (e.g. placement of implants), an accurate localization of the mandibular canal is of utmost importance to avoid injuries to the neurovascular bundle. The aim of the present study was to evaluate, the accuracy of SPIRAL tomography for the localization of the mandibular canal.Material and Methods: By means of the cranex tome multifunctional unit (orion corporation Sordex, Finland), tomographic slices were taken at 4 different locations in each posterior mandible segments (distal to the mental foramen). The mandibles were then sectioned at these 4 sites with a specialize designed drill. The following 4 measurements were preformed both on the tomograms (A, B, C and D) and the bone sections (A’, B’, C’ and D’) at the 4 sites.Results: We found an average mean difference of 0.02 mm with a standard deviation of 0.33 mm. The reported data showed that %95.2 of cases are in ±0.5 mm and %98.4 of cases are in ±1 mm (overestimate and underestimate).Conclusion: SPIRAL tomography using the cranex tome multifunctional x-ray unit provides accurate information and sufficient detail for preoperative planning of implant in the posterior mandible.

Intelligent agents are considered as significant means towards realizing the semantic web vision. On the Semantic Web, integrating ontologies and rules enables software agents to interoperate between them, however, this leads to a problem, that no studies have focused on effective distributed reasoning for integrating ontologies and rules in multiple knowledge-bases. The methods that have been presented for distributed reasoning not only get a lot of times and memory, but also do not lead to a complete and sound reasoning. In this paper, to solve this problem, we present a distributed reasoning system that deals with the representation of the knowledge-base of ORDER sorted logic. This logic is able to describe the hierarchy of predicates and inheritance of expressions that there are in our natural language. To have a distributed reasoning, our proposed method uses the expansion of rigid and valid-non-rigid properties between knowledge-bases. Furthermore, with considering time and the situation of properties for reasoning, the non-rigid properties have not been ignored, in fact, in their valid time and situation, they are used. With this method, we achieve a complete reasoning and, moreover, the extracted knowledge is completely considered in the knowledge-bases and we have a distributed reasoning with high efficiency and sound without missing any information.

Background and Aims: Disc displacement is the most common temporomandibular joint disORDER and MAGNETIC resonance imaging (MRI) is the gold standard in its diagnosis. This disORDER can lead to changes in signal intensity of MAGNETIC resonance (MR). The purpose of this study was evaluation of correlation between relative signal intensity of MR images of retrodiscal tissue, superior and inferior head of lateral ptrygoid muscle with type of anterior disk displacement and condylar head flattening in patients with temporomandibular disORDER (TMD).Materials and Methods: In this retrospective study, 31 MR images of patients who had anterior disc displacement were evaluated. After relative signal intensity measurement for retrodiscal tissue, superior and inferior head of lateral ptrygoid muscle, the correlation between relative signal intensity and type of anterior disc displacement was evaluated with repeated measure ANOVA test. In each of these 3 areas, t-test was used to compare the groups with and without condylar head flattening.Results: The correlation between relative signal intensity of MR images and type of anterior disc displacement in retrodiscal tissue, superior and inferior head of lateral ptrygoid muscle was not significant. There was also no statistically significant correlation between relative signal intensity of MR images and flattening of condylar head in retrodiscal tissue, superior and inferior head of lateral ptrygoid muscle (P>0.05).Conclusion: According to findings of this study, relative signal intensity of MR images in retrodiscal tissue, superior and inferior head of ptrygoid muscle is not a good predictor for type of anterior disc displacement and flattening of condylar head. It seems that this cannot be used as a diagnostic marker for TMD progression.

In this paper, the effect of partial replacement of Nd by Dy atoms on the magneto-elastic properties of Nd2-x,DxFe14C (2-14-1 type) alloys with x = 0.1, 0.3 and 0.5, in a temperature range of 77 K to room temperature have been studied using magnetostriction measurement. The first ORDER MAGNETIC process, FOMP, was determined by measuring the temperature dependence of low field MAGNETIC usceptibility. Results show that an indicative temperature for FOMP, Tsp, increases about 40 K with increasing Dy content, which can be due to the non-negligible role of the higher than second ORDER terms (k4m, k6m, …) of the crystalline field anisotropy of the rare earth sub-lattice. This conclusion is confirmed via magnetostriction results, which show that the partial substitution of Dy for Nd increases the anisotropic magnetostriction. This is attributed to a stronger magneto- crystalline anisotropy. At T > Tsp, Dy partial substitution also causes an increase in the volume magnetostriction, which indicates a positive exchange magnetostrictive effect of Dy- Fe anti- ferroMAGNETIC interaction.

On the circular curve, lateral acceleration affects comfort. On the SPIRAL, both lateral acceleration and jerk affect comfort. The determination of maximum curving speed on the basis of lateral acceleration only is not critical because thelateral acceleration is proportional to the square of speed whereas jerk is proportional to cubic power of speed. Themaximum speed on a curve is thus significantly restricted by the SPIRAL length. In this paper, SPIRAL length is formulatedon the basis of both lateral acceleration and jerk. The proposed formula is applied on curves of various curvature andvalidated against an earlier formula by the author. On the basis of current choice of values of lateral acceleration andjerk, a relation between jerk and lateral acceleration is given that can be used to determine the acceptable value of jerkfor a given lateral acceleration. A single criterion is proposed to decide the requirement of a SPIRAL curve.
