Wormlike micelles, obtained in anionic surfactam sodium oleate （NaOA） solutions in the presence of sodium phosphate （Na3PO4）, were studied using the steady and dynamic rheological methods. The laboratory simulation flooding experiments were used to investigate the effects of flooding for the wormlike micelles system. The results show that the oil recovery is 32.7%. This flooding system is a new type and has high activity with a low cost.

Aqueous zinc-ion batteries(ZIBs) combine the benefits of metallic Zn anodes with those of aqueous electrolytes and are well suited for large-scale energy storage because of their inherent high safety, cost-effectiveness, and eco-friendliness. Currently, the practical application of such batteries is hindered by the poor cycling performance of Zn anodes due to uncontrolled dendrite formation and severe side reactions, although recent reports suggest that these problems can be mitigated through the modification of Zn anodes with metal-based *** that the mechanisms of improving Zn deposition and the structural evolution of metal-based materials have not been systematically reviewed, we herein systematically overview the metal-based materials used to stabilize Zn anodes, starting with a brief summary of the anode working mechanism and the challenges faced by stabilized Zn anodes. Subsequently, the design principles of Zn anodes stabilized by metal-based materials and the related recent progress are reviewed, and the key challenges and perspectives for the future development of such Zn anodes are proposed.

Kounis syndrome is defined as a group of acute coronary syndromes that manifests as unstable vasospasticor nonvasospastc angina, and even as acute myocarda! infarction triggered by the release of inflammatory mediators following an allergic insult.1 Kounis syndrome is a rare and complex syndrome. Instant treatment decisions need to be made once it happens. Here, we defined a case of severe Kounis syndrome, culminating in acute coronary syndrome, as a result of an acute allergic reaction, which was likely related to iodinated contrast media or dextran-40 use. A 71-year-old male patient, with a history of hypertension, no history of coronary heart disease and diabetes, was admitted to our hospital because of intermittent claudication for one year. On admission, his temperature was 36.4℃, pulse was 80 beats/min, respiratory rate was 18 beats/rain and blood pressure was 105/80 mmHg （1 mmHg=0.133 kPa）. Physical examination did not show any sign of heart disease, but the lower extremity arterial pulsation was weak. His artery angiography of abdominal aorta and lower limbs showed that the left iliac artery was completely obstructed. A total of 400 U iodinated contrast media was used during the operation. The patient was back to ward safely. Ten minutes after taking the dextran-40 as a postoperative treatment, he began to present sudden hyperspasmia, transient unconsciousness, skin flushes, excessive sweating and sinus tachycardia （approximately 140 beats/min）. At the same time, his skin temperature decreased and his blood pressure collapsed quickly. He accepted oxygen therapy, fluid replacement, dexamethasone and dopamine immediately. After that the ECG revealed ST elevation of 0.3-0.7 mV in leads II, III, avF, V3.6, and frequent premature ventricular （Figure 1A）. Following the therapy of promethazine, glycerin trinitrate and lidocaine, the shock symptoms was gradually relieved： consciousness was recovered, ST segment gradually went back to normal in half an hour （Figure 1

Herein, the de novo synthesis of atropisomeric benzofurans through the Cu/spirocyclic-pyrrolidine-oxazoline(SPDO) complex catalyze asymmetric formal [3 + 2] cycloaddition between quinones and ynamides is explored, producing a range of structurally diverse axially chiral benzofurans in satisfactory yields with good to excellent enantioselectivities. Furthermore, density functional theory calculations were applied to explain the possible reaction mechanism.

Evolving From principal-subordinate structure of C /S to flexible multileveled distributed structure, i.e. B/S architecture so as to form a wide, distributed and orderly Internet/Intranet integrated management inf ormation system, is the trend of development of application software of the whol e world. Advantages and disadvantages of the two modes: C/S and B/S are compared . It is pointed out that at present onefold B/S mode cannot yet fully fullfil th e demands of some complicated data processing, information statistics and analys is, etc, therefore it still awaits further development of technology to achieve 100% Internet. In this paper, a mode of B/S-C/S-blended multileveled architect ure is discussed; the logical levels of B/S mode is studied; Furthermore, combin ing some up-to-date software developing technology, combinatorial design of di fferent database application technology based on B/S is discussed. The expatiati on is made with following points: (1) Organic combination of the network distrib uted object technology of CORBA and the computation technology among different n etwork operating system ─ Java; (2) Organic combination of two modes of ASP and Plug_in; (3) JDBC Server and JDBC Client; (4) An expanded B/S model, i.e. the c lient application of browser communicates directly with Web server, and the serv er application communicates directly with database server through middle ware.

Although deep learning methods have been widely applied in slam visual odometry over the past decade with impressive improvements， the accuracy remains limited in complex dynamic environments. In this paper， a composite mask-based generative adversarial network is introduced to predict camera motion and binocular depth maps. Specifically， a perceptual generator is constructed to obtain the corresponding parallax map and optical flow from between two neighboring frames. Then， an iterative pose improvement strategy is proposed to improve the accuracy of pose estimation. Finally， a composite mask is embedded in the discriminator to sense structural deformation in the synthesized virtual image， thereby increasing the overall structural constraints of the network model， improving the accuracy of camera pose estimation， and reducing drift issues in the Visual Odometer. Detailed quantitative and qualitative evaluations on the KITTI dataset show that the proposed framework outperforms existing conventional， supervised learning and unsupervised depth VO methods， providing better results in both pose estimation and depth estimation.
