We theoretically study a quantum destructive interference (QDI)-induced photon blockade in a two-qubit driven cavity quantum electrodynamics system with dipole–dipole interaction (DDI). In the absence of dipole–dipole interaction,we show that a QDI-induced photon blockade can be achieved only when the qubit resonance frequency is different from the cavity mode frequency. When DDI is introduced the condition for this photon blockade is strongly dependent upon the pump field frequency,and yet is insensitive to the qubit–cavity coupling strength. Using this tunability feature we show that the conventional energy-level-anharmonicity-induced photon blockade and this DDI-based QDI-induced photon blockade can be combined together,resulting in a hybrid system with substantially improved mean photon number and second-order correlation function. Our proposal provides a nonconventional and experimentally feasible platform for generating single photons.

Let H be an abelian group written additively and k be a positive integer. Let G（H,k） denote the digraph whose set of vertices is just H, and there exists a directed edge from a vertex a to a vertex b if b = ka. In this paper we give a necessary and sumcient condition for G（H, k1） ≈ G（H, k2）. We also discuss the problem when G（H1, k） is isomorphic to G（H2, k） for a given k. Moreover, we give an explicit formula of G（H, k） when H is a p-group and gcd（p, k） = 1.

Background Whether an addition of OAC to double antiplatelet therapy for patients with an indication of chronic oral anticoagulation undergoing PCI-S may improve clinical outcomes is still debated. This meta-analysis aimed to update and re-compare the benefits and risks of triple antithrombotic therapy （TT） with double anti-platelet therapy （DAPT） after in patients who requiring oral anticoagulation after percutaneous coronary interventions with stenting （PCI-s）. Methods Ten reports of observational retrospective or prospective studies were retrieved, including a total of 6296 patients, follow-up period ranging from 1 year to 2 years. Results Baseline characteristics were similar in both groups. The main finding of this study is the overall incidence of major adverse cardiovascular events （MACE）, myocardial infarction （MI） and stent thrombosis was comparable between two groups. Patients with TT was associated with significant reduction in ischemic stroke （OR： 0.27; 95% CI： 0.13-0.57; P=0.0006） as compared to DAPT. We reaffirmed triple therapy significantly increased the risk of major bleeding （OR： 1.47; 95% CI： 1.22-1.78; P 〈0.0001） and minor bleeding （OR： 1.55; 95% CI： 1.07-2.24; P=-0.02）. Conclusions Triple therapy is more efficacious in reducing the occurrence of ischemic stroke in PCI-s patients with an indication of chronic oral anticoagulation （OAC）, compared with DAPT. However, it significantly increased major and minor risk of bleeding. It is imperative that further prospective randomized controlled trials are required to define the best therapeutic strateav for patients with an indication of chronic OAC underaoina PCI-s.

Biofuels became more promising alternative to the fossil fuels because of the depletion of fossil resources, renewability, environmental benefits, and energy security. Ethanolysis of waste cooking oil with hexane as co-solvent was carried out for the production of fatty acid ethyl ester (FAEE). This process reduced the severity of process parameters with high purity biodiesel yield. Process variables such as co-solvent ratio, ethanol to oil molar ratio, reaction temperature and reaction time were optimized. The maximum biodiesel yield of 88% was obtained at ethanol/oil molar ratio of 40:1, co-solvent (hexane) to oil ratio of 0.2% (v/v), reaction temperature of 300°C in 20 min of reaction time. Fatty acid ethyl ester (biodiesel) samples produced from this process were measured and evaluated using GC-MS analytical instrument. Thermo gravimetric analysis (TGA) was also performed to examine the thermal stability of waste cooking oil, ethyl esters and fuel blends. Fuel properties of ethyl esters were determined and compared with the ASTM standards for biodiesel, regular diesel and ethyl esters from different feedstock.
