UNLABELLED The 14-amino-acid peptide bombesin (BN) has a high affinity for the gastrin-releasing peptide (GRP) receptor that is expressed by a variety of tumors. Recently, high densities of GRP receptors were identified by in vitro receptor autoradiography in human prostate and breast carcinomas using [(125)I-Tyr(4)]BN as radioligand. Radiometal-labeled diethylenetriaminepentaacetic acid (DTPA)...

The book with n pages Bn is the graph consisting of n triangles sharing an edge. The book Ramsey number r(Bm, Bn) is the smallest integer r such that either Bm ⊂ G or Bn ⊂ G for every graph G of order r. We prove that there exists a positive constant c such that r(Bm, Bn) = 2n + 3 for all n ≥ cm.

BACKGROUND Research into the neural correlates of bulimia nervosa (BN) psychopathology remains limited. METHODS In this functional magnetic resonance imaging study, 21 BN patients and 23 healthy controls (HCs) completed two paradigms: (1) processing of visual food stimuli and (2) comparing their own appearance with that of slim women. Participants also rated food craving and anxiety levels. ...

OBJECTIVE Studies in Western world patients suggest the possible existence of a subgroup of patients with bulimia nervosa (BN) who display multiple problems with impulsivity, such as suicidal attempts. We assessed impulsive behaviors among BN patients in Japan to discuss them crossculturally. METHOD Impulsive behaviors in 64 BN patients were assessed and multi-impulsivity (MI) was defined acc...

We report the results of a theoretical study of graphene/BN/graphene and BN/graphene/BN trilayers using the van-der-Waals-corrected density functional theory in conjunction with the non-equilibrium Green's Function method. These trilayer systems formed from graphene and BN exhibit distinct stacking-dependent features in their ground state electronic structure and response to an applied electric...

The book with n pages Bn is the graph consisting of n triangles sharing an edge. The book Ramsey number r(Bm, Bn) is the smallest integer r such that either Bm ⊂ G or Bn ⊂ G for every graph G of order r. We prove that there exists a positive constant c such that r(Bm, Bn) = 2n + 3 for all n ≥ cm.

The parent skeleton of BN heterocoronene with three BN units and C3 symmetry was synthesized as a model compound of BN-doped graphene. Further investigation of this graphene-type molecule revealed the important role of BN doping in opening the bandgap and modulating the electronic properties.

Graphene is highly sensitive to environmental influences, and thus, it is worthwhile to deposit protective layers on graphene without impairing its excellent properties. Hexagonal boron nitride (h-BN), a well-known dielectric material, may afford the necessary protection. In this research, we demonstrated the van der Waals epitaxy of h-BN nanosheets on mechanically exfoliated graphene by chemic...

A well known method for convergence acceleration of a continued fraction K(an/bn) is based on the use of modified approximants Sn(ωn) in place of the classical ones Sn(0), where ωn are close to tails f (n) of the continued fraction. Recently (Numer. Algorithms 41 (2006), 297–317), the author proposed an iterative method producing tail approximations whose asymptotic expansion’s accuracy is impr...
