A brief review of Scott measure as a multipartite entanglement criterion

In recent decades, various multipartite entanglement measures have been proposed by many researchers, with different characteristics. Meanwhile, Scott studied various interesting aspects of multipartite entanglement measures and he has defined a class of related multipartite entanglement measures in an obvious manner. Recently, Jafarpour et al. (Int. J. Quantum Inform. 13, 1550047 2015) have calculated the entanglement quantity of two-dimensional 5-site spin system by means of Scott measure. As it was presented in their calculation Q_{2}>Q_{3}. In this paper, we would like to point out that in the 5-qudit system, Q_{2} does not provide a stronger entanglement than Q_{3}, while there is a simple relation between them.Comment: 3 page

Efficient Entanglement Measure for Graph States

In this paper, we study the multipartite entanglement properties of graph states up to seven qubits. Our analysis shows that the generalized concurrence measure is more efficient than geometric entanglement measure for measuring entanglement quantity in the multi-qubit graph states.Comment: 10 pages, 4 table

Tripartite quantum-memory-assisted entropic uncertainty relations for multiple measurements

It is possible to extend the bipartite quantum-memory-assisted entropic uncertainty relation (QMA-EUR) to the tripartite one in which the memory is split into two parts. The uncertainty relations are usually applied to two incompatible observables, however, many kinds of research have been made to generalize the uncertainty relations to more than two observables. Recently, although many relations have been obtained for bipartite QMA-EUR for multiple measurements, the case of tripartite remains unstudied. In this work, we obtain several tripartite QMA-EURs for multiple measurements and show that the lower bounds of these relations have three terms that depend on the complementarity of the observables, the conditional von-Neumann entropies, the Holevo quantities, and the mutual information. Moreover, it is revealed that one of the terms is related to the strong subadditivity inequality. These uncertainty relations are expected to be helpful in the foundations of quantum theory and quantum information processing.Comment: 14pages, 3 figure

Is the conditional entropy squeezing indicts the normalized entropic uncertainty relations steering?

A novel approach is introduced to assess one-way Normalized Entropic Uncertainty Relations (NEUR)-steering in a two-qubit system by utilizing an average of conditional entropy squeezing. The mathematical expressions of conditional entropy squeezing and NEUR-steering are derived and presented. To gain a better understanding of the relationship between the two measures, a comparative analysis is conducted on a set of two-qubit states. Our results reveal that the two measures exhibit complete similarity when applied to a maximally entangled state, while they display comparable behavior with minor deviations for partially entangled states. Additionally, it is observed that the two measures are proportionally affected by some quantum processes such as acceleration, noisy channels, and swapping. As a result, the average of conditional entropy squeezing proves to be an effective indicator of NEUR-steering.Comment: 8 pages, 5 figures. All comments are welcom

Advantage of gravitational cat states in preserving non-classical characteristics

We investigate how resourceful gravitational cat states are to preserve quantum correlations. In this regard, we explore the dynamics of gravitational cat states under different situations such as thermal, classical stochastic, general decaying, and power-law noisy fields. In particular, the one-way steerability, Bell non-locality, entanglement, and purity in two qubits are our main focus. We also address the weak measurement reversal protocol on the dynamics of quantum correlations and purity of the state. Our results show that the gravitational cat states have a reliable and better capacity to preserve quantum correlations and remain one of the good resources for the deployment of quantum information processing protocols

One-Humped Camels (Camelus dromedaries) Hard Ticks Infestation in Qeshm Island, Iran

The economic importance of tick infestation on camels are important as they are important meat and milk producer animals in the less vegetation area of Iran and their health and production are greatly affected by the high tick infestation. In this investigation, tick infestations on camels (Camelus dromedarius) were determined in Qeshm Island, Iran. A total number of 912 adult ticks (472 males and 440 females) were collected and identified. Hyalomma dromedarii was the predominant tick specie and accounted for 61.9% of the adult ticks. Other hard ticks were H. anatolicum excavatum (22 %), H. asiaticum asiaticum (14.2 %), H. marginatum (1.9 %), H. impeltatum (0.4 %) and Ripicephalus bursa (0.4 %). In conclusion, The provision of tick control programs in the Qeshm Island would seem a prerequisite for improving camel meat and milk production

Pharmacological Profile for the Contribution of NO/cGMP Pathway on Chlorpheniramine Antidepressant-Like Effect in Mice Forced Swim Test

Chlorpheniramine, a first-generation antihistamine, is widely used for allergic reactions. Previous studies showed the interaction between antidepressant activity and nitric oxide and cyclic guanosine monophosphate (NO/cGMP) pathway. Thus, we aimed to assess the possible involvement of NO/cGMP pathway in this effect using forced swim test (FST) in male mice. To evaluate the locomotor activity and immobility time, we performed open field test (OFT) and FST on each mouse. Chlorpheniramine was administered intraperitoneally (i.p.) (0.1, 0.3, 1, 10 mg/kg) 30 minutes before FST. To assess the involvement of NO/cGMP pathway, a non-selective nitric oxide synthase (NOS) inhibitor, L-NAME (10mg/kg, i.p.), a selective inducible NOS (iNOS) inhibitor, aminoguanidine (50 mg/kg, i.p.), a selective neural NOS (nNOS) inhibitor, 7-nitroindazole (7-NI, 30 mg/kg, i.p.), a NO precursor, L-arginine (750 mg/kg, i.p.) and a selective phosphodiesterase-5 (PDE-5) inhibitor, sildenafil (5 mg/kg, i.p.) was co-administered with chlorpheniramine. Chlorpheniramine significantly decreased the immobility time at doses of 1mg/kg (P0.05). Moreover, pretreatment with L-arginine (P<0.01) and sildenafil (P<0.001) significantly reduced the anti-immobility effect of chlorpheniramine. These treatments did not alter the locomotor activity of mice in OFT. Our results revealed that the antidepressant-like effect of chlorpheniramine is mediated through inhibition of NO/cGMP pathway
