Benign nocturnal alternating hemiplegia of childhood: a new case with unusual findings
It has been described a neuro developmental disorder labelled âBenign nocturnal alternating hemiplegia of childhoodâ (BNAHC)
characterized by recurrent attacks of nocturnal hemiplegia without progression to neurological or intellectual impairment. We
report a female patient who at 11 months revealed a motionless left arm, unusual crying without impairment of consciousness
and obvious precipitating factors. The attacks occur during sleep in the early morning with lack of ictal and interictal electroencephalographic
abnormalities, progressive neurological deficit, and cognitive impairment. Unlike previous reports of BNAHC our
patient come from a family with a history of both migraine, hemiplegic migraine, and sleep disorders. Our study remarks on the
typical features described in previous studies and stresses the uncommon aspects that could help to identify the disorder which is
likely to have been underestimated. Despite some clinical similarities between BNAHC and familiar hemiplegic migraine and alternating
hemiplegia of childhood, the genetic analyses of our patient did not reveal genetic mutations found in both disorders

Generalized Gluon Currents and Applications in QCD
We consider the process containing two quark lines and an arbitrary number of
gluons in a spinor helicity framework. A current with two off-shell gluons
appears in the amplitude. We first study this modified gluon current using
recursion relations. The recursion relation for the modified gluon current is
solved for the case of like-helicity gluons. We apply the modified gluon
current to compute the amplitude for in the like-helicity gluon case.Comment: 80 pages, 2 figures (appended in pictex), CLNS 91/112
Inflaton Potential Reconstruction and Generalized Equations of State
We extend a previous analysis concerning cosmological fluids with generalized
equations of state in order to study inflationary scenarios. In the framework
of the slow-roll approximation we find the expressions for the perturbation
parameters , and the density perturbation spectra in terms of
the adiabatic index \ga as a function of the universe scale factor. This
connection allows to find straightforwardly \ga corresponding, for example,
to the simplest {\it chaotic} model and to the Harrison-Zeldovich potential and
shows its capability to be applied to more complicate situations. Finally, we
use this description to develop a new approach to the early universe dynamics,
based on a expansion, where is the e-fold number. To this aim, we
introduce a set of suitable dimensionless variables and show that at the
zero-th order in , an improved slow-roll approximation is obtained.Comment: 15 pages, plain Latex, to appear in Mod. Phys. Lett.
Religious tourism and seduction: the case of Sacred Mount of Varallo
Since 2003 the Sacred Mount of Varallo is included in the World Heritage List of UNESCO because it represents a successful integration of architecture and fine art into a landscape of great beauty for spiritual reasons. As the other Sacred Mounts of Piemonte and Lombardia (Italy), it represents a place in witch all visitors (tourist or pilgrims) couldn\u2019t resist the attraction of and environment full of spiritual and natural seduction.
According to these characteristics, the paper aims to define who visits the Sacred Mount of Varallo and which experiences he/she is looking for. In this way we try to understand how a classical religious tourism destination could seduce the third millennium tourist.
The research methodology is based both on official statistical data, and on a questionnaire delivered to visitors
