[Purpose] This study investigated the effects of self-stretching of cervical muscles, because the accessory inspiratory muscle is considered to improve pulmonary function. [Subjects] The subjects were 30 healthy university students 19-21 years old who did not have any lung disease, respiratory dysfunction, cervical injury, or any problems upon cervical stretching. [Methods] Spirometry was used ...

In crooked noses, the lateral walls are different in shape and symmetry. Although the septum is very important to obtain a straight nose, identical and symmetrical lateral walls are needed for a straight looking nasal dorsum. As well as the septum, lateral walls also contribute in nasal skeletal support and stability. Thus, obtaining identical and symmetrical lateral walls is important. In orde...

Force induced stretching of polymers is important in a variety of contexts. We have used theory and simulations to describe the response of homopolymers, with N monomers, to force (f) in good and poor solvents. In good solvents and for sufficiently large N we show, in accord with scaling predictions, that the mean extension along the f axis 〈Z〉 ∼ f for small f , and 〈Z〉 ∼ f 2 3 (the Pincus regi...

In a recent paper Carot et al. considered the definition of cylindrical symmetry as a specialisation of the case of axial symmetry. One of their propositions states that if there is a second Killing vector, which together with the one generating the axial symmetry, forms the basis of a two-dimensional Lie algebra, then the two Killing vectors must commute, thus generating an Abelian group. In t...

THE YOUNG INFANT with cyanotic congenital cardiac disease presents an acute and difficult diagnostic problem. The anomalies responsible for eyanosis in some such infants are now curable surgically while, on the other hand, there remains a group of eyanotic newborn infants in whom the congenital cardiac anomalies are so complex that no surgical procedures for their correction have yet been devis...

Although one can find in literature some contributions reporting on application of Multistrategy Learning (MSL) in different domains, there are only few studies dealing with application of MSL in financial fields. This paper gives an overview about the possibilities of the application of MSL in finance. Presenting some recent empirical results achieved by the authors, we discuss some advantages...

Sir, Cutaneous leishmaniasis (CL) is a protozoan disease present in Old and New Worlds (1, 2). It is endemic in the Mediterranian basin, particularly in the rural areas of Sicily where almost 60% of Italian cases occur. The disease is caused by parasites of the genus Leishmania infantum, carried by specific species of sandflies as Phlebotomus perniciosus and Phlebotomus perfiliewi perfiliewi (3...

In recent months, there has been considerable discussion in the scientific community of the need for increased transparency, openness, and data access [Dealing with Data special section, 11 February, “Making data maximally available,” B. Hanson et al., Editorial, p. 649, and “Climate data challenges in the 21st century,” J. T. Overpeck et al., Perspective, p. 700, as well as (1–4)]. Missing fro...
