By using the latest results of three--dimensional velocity structures about Bobal seaand its adjacent areas (115. 0°-124. 0°E, 36° 0-42. 0°N), we studied the distribution ofb values in the region.

In this paper, by classifying the earthquake sequence types of 17 Ms≥8 before1972, 53 6≤Ms≤7.9 and 44 5≤Ms< 6 since 1924, the authors divide Chinese main-land and its adjacent area into 15 active districts of different earthquake sequence typesusing the method of probability percentage of earthquake sequence type, which was putforward based on the proportion difference of earthquake sequence type itself, as well asdiscuss the source environment of earthquakes with different sequence types.

The earthquakes with M>= 6 of eastern Chinese mainland (λ> = 108°E) and its adjacent area, and that with M>= 7 of western Chinese mainland ( λ <108°E) are called as strong earthquakes in this paper.

Two main electron transport models in NTC thermistors are described, which are nearest neighbor hopping(NNH) model(ρ(T)=CT·exp(T_0/T))and different variable range hopping(VRH) models(ρ(T)=CT~ 2p ·exp(T_0/T)~p).

Notable improvements are observed in drilling sections of 2 293—3 400 m in well Ls-2 with the silicone fluid of density <1.10 g/cm~3 in comparison with drilling in a neighbor well.

Location ofthe neighboring correlated peak shifts linearly from 2.35A for Se to 2.40A for 40 atom% Assubstitute and remains unchanged at higher As concentration.

Based on summarizing regional data and practical investigation, the primary bismuth deposits in South Hunan and its neighboring area can be divided into three bismuth-polymetallic metallogenetic series respectively related to anatectic granite, syntectic granite and magmatic hydrothermal type superimposed by hot brine.

There are two low-resistance layers, with the depth of 15 ± 5 km and nearly under 40 km separately, in the upper and middle crust of Chasang section and neighboring area.

A local-global principle is proved by the second named author in the adjacent paper of this volume.

This wavelet basis is obtained from three wavelet generators by scaling, translation and rotation, and the wavelets are supported either by one corner triangle or a pair of adjacent triangles in the triangulation of level k - 1.

A subset D of V is called a dominating set of G if for every vertex κ,εV-D,κ is adjacent to at least one vertex of D.

The interchange graph G(R,S) is the graph where the vertices are the matrices in U(R,S) and two vertices representing two such matrices are adjacent provided they differ by an interchange.

The paper gives two estimates of the distance between adjacent zeros of solutions of the first-order delay differential equations x'(t)+p(t)x(t-τ)=0 in the case when p(t)≥0 and oscillates or p(t) itself oscillates.

The grain size and element (including redox sensitive elements and terrigenous elements) concentration of surface sediments from the Changjiang Estuary hypoxia zone and its adjacent sea area were measured in this research.

The results show that the tidal waves within the PCRE and in its adjacent area during the period of the PGTM belonged to standing wave or a mixture of standing wave and progressive wave.

The results showed that there might not be the key amino acids responsible for substractive specificity in the NH2-terminal and its adjacent regions of these two transporters, which probably supported the formation of the substrate binding sites.

The model domain covers East Asia and its adjacent oceanic regions.

Edgeworth expansion for nearest neighbor-kernel estimate and random weighting approximation of conditional density

In this paper, Edgeworth expansion for the nearest neighbor-kernel estimate and random weighting approximation of conditional density are given and the consistency and convergence rate are proved.

Here, a characterization of the moment of Lévy measure (restricted on a neighbor of 0) of a full operator-stable μ by eigenvalues of exponent matrix of μ is given.

The networks are constructed by connecting several tight-binding chains with uniform nearest-neighbor hopping integrals.

A monopolized circle is defined as a circle whose center is a tree and whose radius is half of the distance between the tree itself and its nearest neighbor.

one vertex, the points that the ray from the initial vertex intersects respectively with the curve segment, the line connecting the segments end points, and the line connecting the two neighboring vertexes.

A charged mesa, due to its reduced chemical potential, acts as a Coulomb sink and grows at the expense of neighboring neutral mesas.

Species with similar morphological characteristics and from the same areas or neighboring geographical regions were clustered together and had close relationships.

The heart of our mechanism is to migrate some shared files from the overloaded peers to the neighboring free riders automatically and transparently, which enforces free riders to offer services when altruistic peers are heavily overloaded.

In particular, this necessity stems from the prior supposition that neighboring objects of the interrelated array more often belong to one class than to different classes.

In continuing our work on sulfabenzothiazoles containing salt-forming groups, 2-sulfanilylamino-benzothiazole 6- and 5-(or 7-)carboxylic acids were obtained. Their sodium salts are very soluble in water and give neutral solutions. Through the same route,it failed to synthesize the corresponding 4-carboxylic acid,starting either from anthranilic acid or its ethyl ester.They did not give o-thioureidobenzoic acid or its ester,but cyclized to benzoylene thiourea(2- sulfhydryl 4-hydroxyl quinazoline).The same compound...

Attempt to cyclize α-o-carboxyphenyl β-benzoyl thiourea by bromine to 2- benzamido-benzothiazole 4-carboxylic acid also failed,and the desulfured cyclized compound was identified to be 2-benzoyl benzoylene urea. We have,at the same time,cleared up the diversed results of H.Rupe and G.M.Dyson et al.and identified the structure of the Douglass and Dains' compound.

Unlike amines and alcohols reacting with acylisothiocyanates to form acylthioureas andacylthiourethans respectively as the only products,phenols reacted,in general,with the samereagents in two different ways,namely:(Ⅰ)Acylation:(Ⅱ) Addition:where R=C_6H_5,p-BrC_6H_4,and R'=CH_3,H,Cl,COOH,NO_2,etc.In some cases,the former reaction occurred predominately.With phenols containinsproton-repelling groups,such as o-nitrophenol,p-nitrophenol,2,4-dinitrophenol,picric acid,etc.,which react with arylisocyanates with difficulty,however,addition...
