Purpose: To
evaluate the current status of stereotactic body radiotherapy (SBRT) for early
staged non-small cell lung cancer (NSCLC) at main cancer hospitals in China. Methods
and Materials: The questionnaire was sent by mail and email to 21 hospitals,
which include the patient enrollment, treatment technique, dose and
fractionation, quality control, disease control and side effects. Results:
Nineteen hospitals responded. It was found that SBRT has been used for early
staged NSCLC in most of the hospitals participating in the survey. The patient
characteristics and techniques were relatively consistent, but there were many
controversies regarding dose fractionation and quality control. Conclusions:
SBRT for early staged NSCLC has been applied at main cancer hospitals in China.
However, considerable variation exists. The establishment of clinical
guidelines and standardized quality control are crucial for further
improvement.

A multi optical parametric imaging system is introduced and established in order to improve the contrast of object in the fog. A few targets are observed in the fog weather based on the system level radiation model of multi optical parametric imaging and the calibrated model parameters. The results show that the building’s windows can be distinguished clear in the linear polariza-tion, circular polarization and angle of polarization images because of the strong reflected polarization light of the glass; The vehicles in intersection can hardly be seen in the intensity image, and it is fuzzy in degree of linear polarization and angle of polarization image because of the doped polarization information of trees near in fog; The circular polarization image raises the contrast of the vehicles by 20% because the circle polarization of the trees is less in the fog.

Abstract:
This paper tends to prove that the emergence of “financial tsunami” illustrates Hayek’s theory of spontaneous order in a sense. As the main theoretical tool for criticizing the socialism, Hayek defended for the capitalism by the theory of spontaneous order. He thought that it was a kind of moral order and also a kind of material order. It appeared spontaneously, as a result of human evolvement and evolution. The emergence of financial tsunami indicates that the capitalism does not overcome its internal instability or get rid of the periodical economic crisis proved by Marx either.

Abstract:
The generalized Berge-Fulkerson conjecture states that every $r$-graph has $2r$ 1-factors such that each edge is contained in precisely two of them. This conjecture is shown to be equivalent to the statement that every $r$-graph can be covered by $2r-1$ 1-factors. In this paper, we obtain, for any positive integers $r\geq 3$ and $k$, a lower bound of the fraction of edges covered by $k$ 1-factors in $r$-graphs. Moreover, it was announced by Kaiser, Kr\'al and Norine [Unions of perfect matching in cubic graphs, Topics in Discrete Mathematics, in: Algorithms Combin., vol. 26, Springer, Berlin, 2006, pp. 225 - 230] and completely proved by Mazzuoccolo [Covering a cubic graph with perfect matchings, Discrete Mathematics 313 (2013) 2292 - 2296] a lower bound for the fraction of edges covered by $k$ 1-factors in bridgeless cubic graphs (i.e., 3-graphs). Our result extends this to $r$-graphs with $r\geq 3$.

Abstract:
Factors affecting the drilling speed are very complex, such as formation factor (layers lithology, depth, porosity and reservoir pressure), fluid density, drilling parameters (bit pressure and speed), drill types, etc. Although liquid phase underbalanced drilling technology is to increase the penetration rate and shorten the drilling cycle, there is no evaluation model currently, so we cannot evaluate which factors can have a greater impact on speed. Based on the establishment of equivalent density and improvement of ROP (Rate of Penetration) calculation model, this paper is about the application of underbalanced drilling technology to improve drilling speed multiple sizes.

Abstract:
Let $G$ be a bridgeless cubic graph. Consider a list of $k$ 1-factors of $G$. Let $E_i$ be the set of edges contained in precisely $i$ members of the $k$ 1-factors. Let $\mu_k(G)$ be the smallest $|E_0|$ over all lists of $k$ 1-factors of $G$. If $G$ is not 3-edge-colorable, then $\mu_3(G) \geq 3$. In [E. Steffen, 1-factor and cycle covers of cubic graphs, J. Graph Theory (2014) DOI 10.1002/jgt.21798] it is shown that if $\mu_3(G) \not = 0$, then $2 \mu_3(G)$ is an upper bound for the girth of $G$. We show that $\mu_3(G)$ bounds the oddness $\omega(G)$ of $G$ as well. We prove that $\omega(G)\leq \frac{2}{3}\mu_3(G)$. If $\mu_3(G) = \frac{2}{3} \mu_3(G)$, then every $\mu_3(G)$-core has a very specific structure. We call these cores Petersen cores. We show that for any given oddness there is a cyclically 4-edge-connected cubic graph $G$ with $\omega(G) = \frac{2}{3}\mu_3(G)$. On the other hand, the difference between $\omega(G)$ and $\frac{2}{3}\mu_3(G)$ can be arbitrarily big. This is true even if we additionally fix the oddness. Furthermore, for every integer $k\geq 3$, there exists a bridgeless cubic graph $G$ such that $\mu_3(G)=k$.

Abstract:
How topological defects affect the dynamics of particles hopping between lattice sites of a distorted, two-dimensional crystal is addressed. Perturbation theory and numerical simulations show that weak, short-ranged topological disorder leads to a finite reduction of the diffusion coefficient. Renormalization group theory and numerical simulations suggest that longer-ranged disorder, such as that from randomly placed dislocations or random disclinations with no net disclinicity, leads to subdiffusion at long times.

Abstract:
How best to design and redesign high-throughput experiments for zeolite synthesis is addressed. A model that relates materials function to chemical composition of the zeolite and the structure directing agent is introduced. Using this model, several Monte Carlo-like design protocols are evaluated. Multi-round protocols are found to be effective, and strategies that use a priori information about the structure-directing libraries are found to be the best.

Abstract:
We consider the A + A --> emptyset reaction, where the transport of the particles is given by Levy flights in a quenched random potential. With a common literature model of the disorder, the random potential can only increase the rate of reaction. With a model of the disorder that obeys detailed balance, however, the rate of reaction initially increases and then decreases as a function of the disorder strength. The physical behavior obtained with this second model is in accord with that for reactive turbulent flow, indicating that Levy flight statistics can model aspects of turbulent fluid transport.

Abstract:
By analogy with Monte Carlo algorithms, we propose new strategies for design and redesign of small molecule libraries in high-throughput experimentation, or combinatorial chemistry. Several Monte Carlo methods are examined, including Metropolis, three types of biased schemes, and composite moves that include swapping or parallel tempering. Among them, the biased Monte Carlo schemes exhibit particularly high efficiency in locating optimal compounds. The Monte Carlo strategies are compared to a genetic algorithm approach. Although the best compounds identified by the genetic algorithm are comparable to those from the better Monte Carlo schemes, the diversity of favorable compounds identified is reduced by roughly 60%.
