Energy Scattering for Schr\"{o}dinger Equation with Exponential Nonlinearity in Two Dimensions

When the spatial dimensions $n$=2, the initial data $u_0\in H^1$ and the Hamiltonian $H(u_0)\leq 1$, we prove that the scattering operator is well-defined in the whole energy space $H^1(\mathbb{R}^2)$ for nonlinear Schr\"{o}dinger equation with exponential nonlinearity $(e^{\lambda|u|^2}-1)u$, where $0<\lambda<4\pi$.Comment: 20 page

我社资金互助的几大好处和运作时应该注意的问题 = Some benefits and running problems of our financial cooperative

一.确实能解决社员的现实问题，比如：1.春天的种子，夏天的水肥问题。2.孩子上学和应急情况。3.统购统销农药、苹果、梨时会给社员一定的收入。4.共同请养猪、果树专家指导，很便宜很合适。5.社员的钱凑一块买了个耕地机，给社员耕的地又便宜又好。6.今年我们又注册了无公害水果，没有资金就很难办成，这样我们合作社的果农就会卖个好价钱。7.成立了资金互助，社员因对自己的原则，所以他们都会在开大会时集思广益，提出增加效益的好方法来。8.对大会的参加都很热心，因为学习好有关果树技术，养猪技术，沼气知识等技术，才能提高经济效益。 应该注意的就是要尊重社员的民主管理，多倾听社员的合理化建议，多召开社员大会，这样才能调动大家的积极性，减少很所麻烦，因为只有大家都认同，你才会少许多不该发生的问题、矛盾。即使有些有些矛盾发生，大家也能理解。 详细内容去了细谈 This financial cooperative does solve members’ realistic financial problems. For example: When they lack of money in purchasing seeds in Spring or fertilizers in Summer. When they lack of money to afford tuition fee of kids or to deal with some emergencies. Pattern of unified purchase and sale of pesticide, apple and pear could bring our members’ certain income. Sharing the consultant fee for pig raising, fruit tree cultivation is cheaper and more suitable for our members. Our members put their money together to buy a ploughing machine to save the cost of land ploughing. This year, we registered in a new brand of non-polluted fruit. With the new brand, our fruit products could be sold with higher prices. Without money, it is definitely hard to do it. As the purpose of this financial cooperative is to help ourselves, members are quite active in each meeting, they join in brainstorm, always come up with good ideas on profit increase. All of them are enthusiasm in each meeting, as everybody knows mastering knowledge on fruit tree cultivation, pig raising, and biogas utilization etcs. could increase their incomes. Of course, in the running of our association, there are some aspects we should pay more attention to. Respecting each individual for democratic management, listening to their suggestions on rationalization, organizing informal gathering much more frequently, only in those ways it is possible to attract our members’ interests and avoid troublesome. When everybody is in agreement in the discussion, the occurrence of unexpected problems and contradiction could be avoided. And even it happens, everybody could understand you. We can talk about the details after we meet each other

Two new species of the genus Stereodytis Meyrick, S. brevignatha sp. n. and S. acutidens sp. n. are described from China, and Stereodytis increta (Meyrick), comb. n. is transferred from Eulechria Meyrick. The generic characters are emended with description of both male and female genitalia given for the first time. Photographs of the adults and the genitalia are provided

Thrombospondin 1 Deficiency Ameliorates the Development of Adriamycin-Induced Proteinuric Kidney Disease

Accumulating evidence suggests that thrombospondin 1 (TSP1) is an important player in diabetic nephropathy. However, the role of TSP1 in podocyte injury and the development of non-diabetic proteinuric kidney disease is largely unknown. In the current study, by using a well-established podocyte injury model (adriamycin-induced nephropathy mouse model), we examined the contribution of TSP1 to the development of proteinuric kidney disease. We found that TSP1 was up-regulated in the glomeruli, notably in podocytes, in adriamycin injected mice before the onset of proteinuria. ADR treatment also stimulated TSP1 expression in cultured human podocytes in vitro. Moreover, increased TSP1 mediated ADR-induced podocyte apoptosis and actin cytoskeleton disorganization. This TSP1’s effect was through a CD36-dependent mechanism and involved in the stimulation of p38MAPK pathway. Importantly, in vivo data demonstrated that TSP1 deficiency protected mice from ADR induced podocyte loss and foot process effacement. ADR induced proteinuria, glomerulosclerosis, renal macrophage infiltration and inflammation was also attenuated in TSP1 deficient mice. Taken together, these studies provide new evidence that TSP1 contributes to the development of non-diabetic proteinuric kidney disease by stimulating podocyte injury and the progression of renal inflammation

Study on the genus Rhopobota Lederer from China (Lepidoptera: Tortricidae: Olethreutinae)

This paper deals with seventeen species of the genus Rhopobota from China. Five species (R. furcata sp. n., R. orbiculata sp. n., R. fanjingensis sp. n., R. floccosa sp. n. and R. bucera sp. n.) are described as new to science and four species [R. blanditana (Kuznetsov), R. falcata Nasu, R. okui Nasu and R. symbolias (Meyrick)] are new for China. The male of Rhopobota eclipticodes (Meyrick) is described for the first time. Photographs of the adults and genitalia of the species mentioned are provided. A key to the known Chinese species is given based on adults and male genitalia

Tolerance Zone-Based Grouping Method for Online Multiple Overtracing Freehand Sketches

Multiple overtracing strokes are common drawing behaviors in freehand sketching; that is, additional strokes are often drawn repeatedly over the existing ones to add more details. This paper proposes a method based on stroke-tolerance zones to group multiple overtraced strokes which are drawn to express a 2D primitive, aiming to convert online freehand sketches into 2D line drawings, which is a base for further 3D reconstruction. Firstly, after the user inputs a new stroke, a tolerance zone around the stroke is constructed by reference to its polygonal approximation points obtained from the stroke preprocessing. Then, the input strokes are divided into stroke groups, each representing a primitive through the stroke grouping process based on the overtraced ratio of two strokes. At last, each stroke group is fitted into one or more 2D geometric primitives including line segments, polylines, ellipses, and arcs. The proposed method groups two strokes together based on their screen-space proximity directly instead of classifying and fitting them firstly, so that it can group strokes of arbitrary shapes. A sketch-recognition prototype system has been implemented to test the effectiveness of the proposed method. The results showed that the proposed method could support online multiple overtracing freehand sketching with no limitation on drawing sequence, but it only deals with strokes with relatively high overtraced ratio

CD47 Deficiency Protects Mice from Diet-Induced Obesity and Improves Whole Body Glucose Tolerance and Insulin Sensitivity

CD47 is a transmembrane protein with several functions including self-recognition, immune cell communication, and cell signaling. Although it has been extensively studied in cancer and ischemia, CD47 function in obesity has never been explored. In this study, we utilized CD47 deficient mice in a high-fat diet induced obesity model to study for the first time whether CD47 plays a role in the development of obesity and metabolic complications. Male CD47 deficient and wild type (WT) control mice were fed with either low fat (LF) or high fat (HF) diets for 16 weeks. Interestingly, we found that CD47 deficient mice were protected from HF diet-induced obesity displaying decreased weight gain and reduced adiposity. This led to decreased MCP1/CCR2 dependent macrophage infiltration into adipose tissue and reduced inflammation, resulting in improved glucose tolerance and insulin sensitivity. In addition, CD47 deficiency stimulated the expression of UCP1 and carnitine palmitoyltransferase 1b (CPT1b) levels in brown adipose tissue, leading to increased lipid utilization and heat production. This contributes to the increased energy utilization and reduced adiposity observed in these mice. Taken together, these data revealed a novel role for CD47 in the development of obesity and its related metabolic complications
