We can compress the word ‘banana’ as xyyz, where x = ‘b’, y = ‘an’,z = ‘a’. We say that ‘banana’ encounters yy. Thus a ‘coded’ version of yy shows up in ‘banana’. The relation ‘u encounters w’ is transitive, and thus generates an order on words. We study antichains under this order. In particular we show that in this order there is an infinite antichain of binary words avoiding overlaps. AMS Su...

We consider the one-dimensional Ising-like fully anisotropic S= 1 2 Heisenberg antiferromagnetic Hamiltonian and study the dynamics of domain wall excita-tions in the presence of transverse magnetic field h x. We obtain dynamical spin correlation functions along the magnetic field S xx (q, ω) and perpendicular to it S yy (q, ω). It is shown that the line shapes of S xx (q, ω) and S yy (q, ω) ar...

20. yy. bestecileri arasında genellikle yazdığı film müzikleri ile uluslar arası görünürlüğü öne çıkmış olan İtalyan besteci Nino Rota (1911-1979), sahne üzeri için konser ele alındığı zaman müzikal dünyası bütünüyle anlaşılır hale gelmektedir. 19.yy.’da opera sanatı, bestecilik ve performans bakımından toplumsal desteği zirvede geçirmiş fakat 20.yy.’da değişen dönüşen politik şartlar diğer for...

Peptide YY concentrations in both rectal mucosa and fasting plasma, which were produced by endocrine cells in the lower gastrointestinal tract, were measured in normal subjects and patients with ulcerative colitis by specific radioimmunoassay and were examined in the relation to histopathological changes and extent of lesions of ulcerative colitis. Peptide YY levels of rectal mucosa (11.0 +/- 1...

Seminalplasmin, the major basic protein of bull semen, an important regulator of calcium transport in bovine sperm and a positive modulator of the zona pellucida-induced acrosome reaction, is shown to be a recently created member of the neuropeptide Y gene family. Sequence analysis of the bovine peptide YY-pancreatic polypeptide gene cluster reveals an unexpected and extensive homology between ...

We present a complete description of $2$-dimensional equations that arise as symmetry reductions fourf $3$-dimensional Lax-integrable equations: (1) the universal hierarchy equation~$u_{yy}=u_zu_{xy}-u_yu_{xz}$; (2) 3D rdDym equation $u_{ty}=u_xu_{xy}-u_yu_{xx}$; (3) The basic Veronese web $u_{ty}=u_tu_{xy}-u_yu_{tx}$; (4) Pavlov's $u_{yy}=u_{tx}+u_yu_{xx}-u_xu_{xy}$.
