In our work, we have explored the phase space nonlinear coherent-Kerr-cavity nonclassicality and purity loss induced by off-resonant intensity-dependent cavity-qubit interactions under atomic spontaneous-emission dissipation effect. The generation of the cavity purity loss (mixedness) dynamics, by using von Neumann entropy, is linked to the nonclassicality's Wigner distribution dynamics, which is investigated at spastic times chosen based on the von Neumann entropy's cavity dynamics. The temporal evolution of the largest negativity of the Wigner distribution is investigated under the physical system effects of the qubit spontaneous-emission dissipation, the detuning as well as the coherent-Kerr-cavity nonlinearity. The growths and the stability of the purity loss and the Wigner distribution negativity loss have the same behaviors. They depend on the Kerr-like nonlinearity and the dissipation couplings. These losses and their stability can be enhanced by increasing the dissipation coupling. It is found that the nonclassicality's phase space Wigner quasi-probability distribution and the mixedness of the generated coherent-Kerr-cavity states are highly sensitive to the physical system effects.

In this study, we investigate the impact of the XYZ-DM-Heisenberg model on quantum resources, including local quantum Fisher information, concurrence, and Jensen-Shannon coherence, in the presence of intrinsic decoherence. By exploring various spin-exchange interactions, with a focus on the role of the y -DM interaction, we reveal how these interactions affect quantum correlations and coherence dynamics. We find that the system transitions from separability to the generation of quantum properties when spin interactions are introduced. The specific parameter choices significantly influence the dynamic map of quantum functions. Notably, strong y -DM interaction, in combination with equal spin interaction, leads to pronounced fluctuations, while weak DM interaction results in sudden death and rebirth in the x direction. Additionally, ferro- and anti-ferromagnetic regimes impact the quantum functions differently. In the presence of intrinsic decoherence, fluctuations decrease, and coherence remains robust compared to the local quantum Fisher information and entanglement, reducing loss. [ABSTRACT FROM AUTHOR]

Electric cars are becoming more and more popular. In 2019, 2.2 million electric cars were sold around the world, and that number increased in 2021 to 6.6 million. Microgrids prove to be a viable resolution to the challenge of integrating large-scale electric vehicles and renewable energy sources into the electric power system, given the exponential expansion of both industries and the demand for electric vehicles (EVs). Additionally, the principal policy objective of the government is to enhance the accessibility of public recharge stations designed to accommodate EVs. The study applies cutting-edge technologies to the development of fast-charging (FC) stations. Because DC charging offers unlimited power and quick power transfer, vehicle-to-grid technology can be implemented in a microgrid using DC power transmission. However, incorporating EVs into a microgrid system presents some operational difficulties. In this study, these difficulties are related to power quality (PQ) problems like harmonics in power systems, which have an impact on consumers as well as utilities. The efficacy of the control system was assessed through the simulation of design models employing MATLAB-based vector control and constant current-constant voltage (CC-CV) techniques. Through the reduction of the system's total harmonic distortion (THD), both strategies contribute to the enhancement of the PQ and performance of the control system as assessed by these simulations. Based on the findings, the controller demonstrated a decrease in THD and an enhancement in waveform quality, resulting in high accuracy and good performance. The DC-Bus receives power transmission from the AC network that is near the unity power factor (PF) and is distinguished by a sinusoidal current. [ABSTRACT FROM AUTHOR]

This study explores the dynamics of atomic mixedness and phase space quasi-probability information of one of two moving atoms trapped in a cavity filled by a coherent field. The atom-photon interactions are considered with the resonance case through nonlinear intensity-dependent coupling. We investigate the impacts of the atom-photon and atomic motion couplings on the dynamics of the atomic Wehrl entropy's mixedness and phase space Husimi distribution information. By helping Wehrl entropy's mixedness dynamics, the dynamics of acceleration and enhancement of the generation of the atomic phase space quasi-probability coherence are examined, and the Husimi distributions of the generated atomic states of one of the two moving atoms are explored. The results are shown that the atomic Husimi distribution and Wehrl entropy's mixedness are susceptible to an increase in the atom-photon and the atomic motion couplings. Therefore, the atomic phase space Husimi distribution coherence can be improved by increasing the atomic motion and nonlinear atom-photon couplings. [ABSTRACT FROM AUTHOR]

To evaluate the effectiveness of pain neuroscience education (PNE) and transcutaneous vagal nerve stimulation (tVNS) for fibromyalgia (FM) patients, as one of the chronic pain treatment modalities. The study was conducted on 99 patients that were divided into 3 groups (n = 33 each): Patients in group A received 6 sessions of tVNS twice weekly (25 Hz for 30 min), group B received 6 sessions of tVNS twice weekly (25 Hz for 30 min) and 3 sessions of PNE once weekly (for 30 min) and group C received 3 sessions of PNE once weekly (for 30 min). The follow up done immediately after the end of the sessions by Visual Analogue Scale score, Fibromyalgia Impact Questionnaire (FIQ), Pain catastrophizing scale questionnaire (PCS-Q, Pain DETECT questionnaire (PD-Q) and state trait anxiety inventory (STAI Q) self-reported questionnaire. The mean age of patients was 33.3 ± 8.2 years and they were 86 females and 13 males (F:M 6.6: 1) and the 3 groups were matched for age (p = 0.15) and gender (p = 0.13). During the procedures no side effects were encountered. The 3 groups showed significant improvement of FM symptoms assessed by VAS, FIQ, PCS-Q, PD-Q and STAI-Q (state and trait), but group B showed the best results percentage of improvement (60%, 34.4%, 54.2%, 40%, 51.1% and 52,2% respectively). Combined tVNS and PNE are more effective than PNE alone or VNS alone in management of FM. Further studies with long term follow up to assess the long-term effect of tVNS or PNE.

This paper describes a lithium-ion battery (LIB) hybrid equalization (HE) structure. There are two primary strategies for voltage equalization (EQ): passive and active. Active equalization (AE) moves energy between the LIBs, whereas passive equalization (PE) wastes energy. PE strategy has the benefit of being easy to put into action, but at the same time, it requires more time to equalize and results in a loss of energy. Although it is difficult to implement, AE has a shorter EQ time and less energy loss. Combining these two methods simultaneously controls a pack of LIBs and equalizes voltage. This article offers recommendations on a cell level (CL) and between stacks. Some LIBs were outfitted with varying state of charge (SOC) levels to simulate a cell imbalance. Different topologies were tested, including combined AE and PE at the pack level and PE and AE topologies at the CL. Response times and SOC levels are used to compare the results. Compared to strictly AE or PE strategies, the HE showed encouraging results regarding EQ time and autonomy. This combination offers a solution that enables one to achieve minimal HE time while maintaining appropriate SOC. [ABSTRACT FROM AUTHOR]

We have explored the non-locality of two qubits interacting time-dependently with a nondegenerate parametric amplifier cavity fields in the presence of the Stark shift interaction term. The time-dependent two-qubit reduced density matrix is calculated numerically when the cavity fields are initially in two entangled coherent states. We investigate the non-locality via local Fisher information and negativity. It is shown that, the generated non-locality depends on the time-dependent two-qubit location, the Stark shift interaction, the difference between the mean photon numbers of the two cavity fields as well as the initial intensity coherent fields. The agreement of the generated correlations presented by the local Fisher information and the negativity depends on the physical parameters. The Stark shift non-linearity and the difference between the mean photon numbers leads to reducing the generated correlations. The local Fisher information is more robust against the Stark shift interaction than the negativity. [ABSTRACT FROM AUTHOR]

All over the world, photovoltaic (PV) systems have now become a hopeful way to obtain transition to sustainable energy. Under different operating conditions, the voltage and maximum power generated by PV arrays can differ. The present study aims to employ a PV experimental model to propose a technique for tracking the maximum power point using a new control method for DC-DC converters. The Perturb and Observe (P&O) and Incremental Conductance Method (ICM) were combined to obtain a new combination method. The test system comprises a PV model, a DC-DC converter, a battery, an inverter, and a load. Simulation and experimental results that are totally compatible with each other demonstrate that the devised method can be used as a platform for the PV maximum power point tracking (MPPT) systems.

We have studied the dielectric properties and electrical conductivity for pure bentonite (Ben) and Ben loaded with 1.0%, 3.0% and 10.0% Ni composition within the temperature range 25°C–110°C and over the frequency range (100 Hz–0.3 MHz). The dielectric permittivity of pure Ben and Ni/Ben composite decreased with increasing frequency and temperature. We observed two relaxation processes in the characteristics of the electric modulus as a function of frequency and temperature. For both pure Ben and Ni/Ben, the activation energy decreased with increasing frequency and further decreased by adding 1.0, 3.0 and 10.0 wt.% Ni. Thus, the conduction mechanism in Ni/Ben has been associated with small polaron tunnelling. [ABSTRACT FROM AUTHOR]

Based on commercial bentonite (bento) and two metal precursors, including NiCl2 and CoCl2, diverse series of composites were prepared by incipient wet impregnation. The prepared composites were characterized by X-ray diffraction, scanning electron microscopy and energy-dispersive X-Ray spectroscopy. X-ray diffraction studies show that the crystallite size decreased as increasing the wt. % of cobalt. Moreover, the presence of Co in the EDX spectra for all bento concentrations, suggests its successful incorporation and probably the formation of Ni–Co oxide. The dielectric constant ε′, the dielectric modulus (M′, M′′) and the ac conductivity (σac) were also studied. It was found that ε′ decreases with frequency in all samples, a clear dielectric α relaxation observed from dielectric loss M′′. σac decreases by increasing Co content and the conduction mechanism is correlated barrier hopping (CBH). σac(T) is thermally activated and the activation energy Ea decreased with increasing Co content.

In this paper, we consider a class of doubly truncated distributions. Based on this class, recurrence relation for moment generating functions of record values is derived. Recurrence relations for single and product moments of record values are deduced from the main results. Several of the known distributions can be seen as special cases of the used class, which includes the left, right and non-truncated distributions. So, we discuss in detail some examples of these distributions based on the main results. In general, for any distribution in the considered class, we reach to a general form to find recurrence relations of moment generating function and moments. [ABSTRACT FROM AUTHOR]

• We have demonstrated experimentally an observation of the pairing symmetry crossover in iron pnictide. • This reveal an unexpected connection between the disorder of cuprate‐ and iron‐based superconductors suggesting that the superconducting gap structure of iron-based superconductors is not universal. • It is quite different from that of cuprates in which almost all have a nodal pairing state. • This also provides insight on the origin of the high superconductivity of Fe-based superconductors by resolving the pure role of carrier doping. • We have discovered a comprehensive and exotic phase diagram of BaFe2-xNixAs2. • The phase diagram is the first comprehensive and clean carrier-dependent phase diagram for an electron doped iron pmictide through studying the 13 doping levels. • Its establishment is an important step in our understanding to various Fe-based superconductors. • Our findings tackle an answer of a longstanding questions concerning the pairing symmetry in Fe-based superconductors. • Moreover, our results will trigger an immediate theoretical interest on understanding the role of introducing disorder in iron‐based superconductivity. In the phase diagram of iron pnictides, superconductivity arises at the border of antiferromagnetism, which raises the question of the role of symmetry of the gap and quantum criticality. Although more than 15-years of extensive research, the microscopic origin of the pairing symmetry inside the superconducting (SC) dome and its link to quantum criticality still remains elusive. Here, we report two new findings on BaFe 2− x Ni x As 2 : (1) A sharp peak in the x -dependence of the lower and upper critical fields, the SC critical current density J c , the size of the jump in the specific heat ΔC el / T and the Sommerfeld coefficient (γ) at the optimum composition x = 0.10, where the SC transition temperature T c reaches a maximum. Our obtained reliable values as a function of doping of the normal-state Sommerfeld coefficient increase with doping, illustrating the strong competition between magnetism and superconductivity and attributed to closing of spin density wave gap with Ni doping. (2) We show that doping induced a sudden change of the gap structure from nodeless to nodal. Our results imply that the superconductivity in BaFe 2− x Ni x As 2 is closely linked to the quantum criticality and is characterized by a complex order parameter. [ABSTRACT FROM AUTHOR]

Highlights • Cyclophosphamide is used for treatment of various tumors and severe manifestations of systemic autoimmune diseases. • It has deleterious effect on testis histological structure and decrease in c-kit protein expression. • Cyclophosphamide caused decrease in serum testosterone level, abnormality in sperm morphology and structural chromosomal aberration. • Changes occurred with cyclophosphamide treatment can be attributed to oxidative stress as well as DNA damaging effect. • ZnO NPs effectively ameliorated cyclophosphamide induced testicular changes at the histopathological, biochemical and cytogenetic level. Abstract Despite its wide range of application, cyclophosphamide (CP) exhibits a wide range of adverse effects including reproductive toxicity. The emerging field of zinc oxide nanoparticles (ZnO NPs) therapy may provide a new hope for prevention of CP induced gonadal toxicity. Herein, we aim to investigate the possible role of ZnO NPs as a new strategy to protect against CP induced testicular injury. Sixty adult male albino rats were divided into 3 groups; control, CP treated and CP + ZnO NPs treated groups. CP group was injected with CP (5 mg/kg/day), whereas CP + ZnO NPs group was concomitantly injected with CP and ZnO NPs (5 mg/kg/day). Testicular specimens were processed for histological, ultrastructural and c-kit immunohistochemical study. Biochemical analysis for tissue malondialdehyde and serum testosterone was done in addition to sperm morphology assay and cytogenetic study. Our results revealed that CP induced deleterious testicular histopathological, biochemical and genetic alterations that were effectively prevented by ZnO NPs. [ABSTRACT FROM AUTHOR]

Sesame (Sesamum indicum L.) from the family of Pedaliaceae is one of the most ancient crops and oilseeds. It was a major oilseed crop in the ancient world due to its easiness of extraction, great stability, and resistance to drought. One of the most dangerous pathogens that affect sesame and other plants worldwide is phytoplasma. Phytoplasma can cause different character of symptoms such as: phyllody, the common symptom caused by phytoplasma infection, stunting, changing the color of leaves from green to yellow and alteration of the floral parts into leafy structures bearing no capsule and seeds, which consider a serious threat for the production of sesame in many countries. On the other hand, effect of the phytoplasma infection on plant enzymes such as Peroxidase and Polyphenol oxidase and hormones like Auxins, Cytokinin, Gibberellins and Abscisic acid were studied. Electron microscopy assay was used to verify the cellular changes which conducted as a result of phytoplasma infection. Infected sesame samples which examined by PCR were used as an exporter of phytoplasma and directly applied for electron microscopy test and the analysis of enzymes and hormones. Transmission electron microscopy (TEM) was used to detect ultra-structural changes in infected sesame plants. [ABSTRACT FROM AUTHOR]

Objective: To assess the diagnostic accuracy of combined use of conventional grayscale US and sono-elastography in differentiating benign and malignant solitary thyroid nodules. Materials and methods: This prospective study included 50 patients with solitary thyroid nodules being evaluated using grayscale US followed with sono-elastography (USE). Suspicious conventional sonographic data for malignancy then evaluated using USE were classified according to Rago criteria with calculation of strain ratio. The diagnostic performances of grayscale US, elastography with Rago criteria, for predicting thyroid malignancy were compared and cutoff value for strain ration was statistically analyzed. Finally all patients with solitary nodule were subjected to US-guided FNAC and 35 patients recommended for surgery in the form of 12 patients underwent total thyroidectomy and 23 patients underwent thyroidectomy with neck dissection. Results: 30 females (60%), and 20 males (40%) were included (Mean age 38) with final diagnosis comprised 29 (58%) pathologically proved benign thyroid nodules and 21 (42%) pathologically proved malignant nodules. US showed significant relation between markedly hypo-echogenicity, oval than tall, margin irregularity, presence of micro-calcification with diagnosis of thyroid malignancies with p value <0.001. Regarding sonoelastography, there was significant relation between elastography scores 4 and 5 and thyroid malignancies showing sensitivity of 80%, a specificity of 100%, and p value <0.001. The most accurate strain ratio cutoff value among studied cases was 2.52. Combination of grayscale US and sono-elastography yielded better results with sensitivity of 92%, specificity of 95%, PPV of 89%, NPV of 92% and diagnostic accuracy or efficacy of 96%. Conclusion: Combined use of USE and grayscale US, showed superior performance in the differentiation of malignant and benign thyroid nodules compared with each technique alone. Suspicious US criteria with elasticity Rago scores 4 and 5 and strain ratio more than 2.52 are the most predictive signs of malignancy. [ABSTRACT FROM AUTHOR]

Pseudomyxoma pleurii is a rare disease that is defined by the pleural extension of pseudomyxoma peritonei, usually secondary to a mucinous neoplasm of the appendix or ovary. It is characterized by diffuse mucinous deposits on the pleural surface. A 31-year-old woman presented to the hospital with dyspnea, an increased respiratory rate, and decreased oxygen saturation. Following an appendectomy for a perforated mucinous appendiceal tumor eight years ago, the patient underwent multiple surgeries for the resection of mass deposits in the peritoneal cavity. At presentation, her chest computed tomography with contrast revealed cystic mass deposits on the right-side pleura with a massive multi-locular pleural effusion mimicking hydatid cyst. Upon histopathologic examination, multiple small cystic structures lined by tall columnar epithelium with basally placed bland nuclei floating in the mucin pools were noted. Pseudomyxoma peritonei often leads to abdominal distention, intestinal blockage, anorexia, cachexia, and eventually death. It rarely spreads outside the abdomen, and its extension to the pleura is extremely unusual, with only a small number of cases documented in the literature to date. Radiologically, pseudomyxoma pleurii may resemble hydatid cyst of the lung and pleura. Pseudomyxoma pleurii is a rare entity with a poor prognosis that usually arises secondary to Pseudomyxoma peritonei. The risk of morbidity and mortality is reduced by early diagnosis and treatment. The present case places emphasis on the inclusion of pseudomyxoma pleurii in the differential diagnosis of pleural lesions in patients with the history of appendiceal or ovarian mucinous tumors. • Pseudomyxoma pleurii (PMXP) is a rare entity that may mimic hydatid cyst disease radiologically. • Although PMXP has a poor prognosis, the risk of morbidity and mortality can be reduced by early diagnosis and treatment. • PMXP should be included in the differential diagnosis of pleural lesions in patients with the history of mucinous tumors.

Teratoma is a germ cell tumor originating from pluripotent germ cells and embryonal cells that commonly occurs in the gonads with only 15 % of it arising in extragonadal sites. In infants and children, teratomas of the head and neck are uncommon that comprise 0.47 %–6 % of all teratomas, and their occurrence in parotid gland is extremely rare. It is considered a diagnostic pitfall preoperatively, and their definite diagnosis can only be made upon surgery followed by histopathological examination. We present a unique case of parotid gland teratoma in a 9-month-old girl who was brought to the hospital by her parents with right side parotid region swelling since birth. The ultrasonographic findings were suggestive of cystic hygroma. Upon surgery, the mass was completely excised with a part of parotid gland. The diagnosis of mature teratoma was made based on the histopathologic examination. No tumor recurrence was noted during the 4-month postoperative follow-up. Teratoma of the parotid gland is an extremely rare entity that may mimic diverse benign and malignant tumors of the salivary gland. Patients often present to the health care facility with a parotid gland swelling leading to defacement. Complete surgical resection of the tumor is considered the best treatment approach with careful preservation of facial nerve. Due to the scarcity of information available regarding the behavior and clinical management of parotid gland teratoma in the literature, a good follow-up of patient is required to exclude potential recurrency and neurological deficit. • Craniocervical teratoma in children and infants is an extremely rare entity that comprise 0.47 % - 6 % of all teratomas. • Teratoma of the parotid gland requires a good follow-up of patient to exclude the possible recurrence and neurological deficit. • Here we present the first case of a congenital mature cystic teratoma arising in parotid gland in an infant.

The aim is to determine the impact of combined use of health-improving fitness methods of Pilates and Bodyflex on the level of students' psychophysiological and functional capabilities. Materials: 46 high school students took part in the study. Methods of the research are psychophysiological (speed detection of simple and complex reaction in different test modes, level of functional mobility and strength of the nervous system). We measured the indicators: blood pressure, stroke volume of blood, heart rate during rest and exercising. There was determined the indices of submaximal workability and autonomic balance. We used also the methods of pedagogical experiment and mathematical statistics. Results: We observed positive effect of the developed methods to the level of students' psychophysiological and functional capabilities. As a result of their application we saw significant decrease in the latent time of simple visual and motor reaction, complex visual and motor reaction, time duration of the test "level of functional mobility of nervous processes" in the feedback mode in the experimental group. The boys showed significant increase in stroke volume (from 58 ml to 62.1 ml, the threshold of anaerobic metabolism from 123.4 beats per min-1 to 141.4 beats per min-1. The girls also showed significant increase in stroke volume (from 58.3 ml to 62.5 ml, the threshold of anaerobic metabolism from 123.7 beats per min-1 to 143.3 beats per min-1. The indicators of energy-supply systems increased (S.A. Dushanin's technique). We marked the improvement in efficiency of the cardiovascular system (increased heart rate variability from 322.12 ms to 354.43 ms, reduction of mode amplitude of RR-intervals from 34.09% to 21.54%). Conclusions: It is recommended to use complex "Pilates" and "Bodyflex" systems in learning process. It contributes to the functional and psychophysiological capabilities of students. The use of Bodyflex and Pilates improves strength of nervous processes and students' submaximal workability. [ABSTRACT FROM AUTHOR]

Nonclassical correlations dynamics of local quantum Fisher information, trace-norm measurement-induced nonlocality, and log-negativity are investigated in a symmetric spin–orbit model. This model is described by a Heisenberg XYZ two-spin system exposed to the magnetic field and Kaplan–Shekhtman–Entin-Wohlman–Aharony (KSEA) interaction under the intrinsic decoherence effects. To evaluate the resourcefulness of this model for the generation and preservation of quantum correlations, we consider two qubits that are initially prepared in two different states, namely uncorrelated and maximally correlated states. The magnetic field is discovered to be effective at generating and preserving nonclassical correlations. Besides, we find that the KSEA interaction can alter the generation, preservation, and revival features of nonclassical correlations in the two-qubit system. However, the bipartite nonclassical correlations become extremely fragile when intrinsic decoherence effects appear. • Intrinsic decoherence effects on dynamics of nonclassical correlations. • Heisenberg XYZ two-spin system exposed to magnetic field and KSEA interaction. • Long-time protection of quantum correlations under intrinsic decoherence effects.

In this paper, maximum likelihood and Bayes estimates of the parameters for Burr type χ distribution based on doubly type II censored sample of dual generalized order statistics are obtained. Two different cases are considered. In the first case, the shape parameter is estimated when the scale parameter is known while in the second case the estimators for scale and shape parameters are obtained when both parameters are assumed to be unknown. For Bayesian estimation, Monte Carlo Integration is used to improve the approximation of resulting integrals. Simulation studies are conducted to demonstrate the efficiency of the proposed methods through two special cases. [ABSTRACT FROM AUTHOR]

This paper describes the synthesis and characteriszation of pure bentonite as well as nanocomposites with varying ratios of nickel (Ni) and metallic copper (Cu) based on the wet impregnation method. Both XRD (X-ray diffraction) and SEM-EDX (scanning electron microscopy with energy-dispersive X-ray spectroscopy) analyses confirm the structural characteristics of the composites. The emergence of a Ni peak in the Cu/bentonite EDX spectra indicates that it is in the proper spot and is most likely the creation of Ni–Cu oxides. Furthermore, the dielectric characteristics and electrical conductivity of Ni-loaded Cu/bentonite composites were also measured at temperatures ranging from 25 °C to 120 °C and at a frequency range of 100 Hz–0.3 MHz to investigate the impact of varying Ni ratios. For all nanocomposite samples, the dielectric constant (ε ′) was shown to decrease with increasing frequency and rise with increasing Ni content. The dielectric modulus M ″ resulted in a significant decrease in relaxation time. The associated barrier hopping conduction process was discovered to boost electric conductivity σ ac at higher frequencies (CBH). [ABSTRACT FROM AUTHOR]

In this work, we demonstrate that the thermal nonclassical correlations can enhance and become more stable under the magnetic field and second-order spin–orbit interaction effect. Also, we show that the local quantum uncertainty measure can reveal purely quantum correlations beyond other quantifiers of correlations. Our analytical model describes a Heisenberg XYZ two-spin system with an inhomogeneous magnetic field and spin–orbit interaction. A special emphasis is devoted to local quantum uncertainty, concurrence, and Bell-nonlocality measures to investigate the correlations of the bipartite-system at the equilibrium temperature. Our results indicate that temperature, magnetic field, and magnetic field inhomogeneity with DMI and Kaplan–Shekhtman–Entin-Wohlman–Aharony (KSEA) exchanges all play a role in determining the degree of correlation between the quantum spins to some extent. The KSEA interaction greatly enhances the quantum correlation in the system whereas quantum quantifiers are more stable under the influence of the external magnetic field, especially when inhomogeneous and homogeneous magnetic field are near to zero. Furthermore, these findings suggest that the thermal LQU captures a stronger quantum correlation than the Bell-nonlocality and entanglement measures. • New approaches to new solutions of spin–orbit system. • Non-local the correlations of the bipartite system. • Heisenberg XYZ two-spin system. • Effect of inhomogeneous magnetic field and spin–orbit interaction.
