The Mass-spectrum of Indium [PDF]
SINCE the last report on the results of the massspectrograph (NATURE, September 22) the work with that instrument has been very disappointing. Owing partly to the capricious behaviour of the apparatus for producing accelerated anode rays, with consequent difficulties in obtaining intense beams, and partly, no doubt, to the unfavourable properties of ...

Light Meson Mass Spectrum from Gauge Fields on Supergravity Backgrounds [PDF]
We propose that the spectrum of light mesons (the $\pi$ and $\rho$, together with their radial excitations) can be calculated in the limit of vanishing light quark masses by studying gauge theory (open string theory) on suitable higher dimensional background geometries.

Charm mass corrections to the bottomonium mass spectrum [PDF]
The one-loop corrections to the bottomonium mass spectrum due to the finite charm mass are evaluated in the framework of the relativistic quark model. The obtained corrections are compared with the results of perturbative QCD.

The masses of affine Toda theories are known to correspond to the entries of a Perron-Frobenius eigenvector of the relevant Cartan matrix. The Lagrangian of the theory can be expressed in terms of a suitable eigenvector of a Coxeter element in the Weyl ...

On the Thermomechanics of Hadrons and Their Mass Spectrum
A little-known thermomechanical relation between entropy and action, originally discovered by Boltzmann in the classical domain, was later reconsidered by de Broglie in relation to the wave–particle duality in the free propagation of single particles. In

Background Cisplatin, the alkylating agent of platinum(II) (Pt(II)), is the most common antitumor drug in clinic; however, it has many side effects, therefore it is higly desired to develop low toxicity platinum(IV) (Pt(IV)) drugs.
