A Smart Wizard System Suitable for Use With Internet Mobile Devices to Adjust Personal Information Privacy Settings
The privacy of personal information is an important issue affecting the
confidence of internet users. The widespread adoption of online social networks
and access to these platforms using mobile devices has encouraged developers to
make the systems and interfaces acceptable to users who seek privacy. The aim
of this study is to test a wizard that allows users to control the sharing of
personal information with others. We also assess the concerns of users in terms
of such sharing such as whether to hide personal data in current online social
network accounts. Survey results showed the wizard worked very well and that
females concealed more personal information than did males. In addition, most
users who were concerned about misuse of personal information hid those items.
The results can be used to upgrade current privacy systems or to design new
systems that work on mobile internet devices. The system can also be used to
save time when setting personal privacy settings and makes users more aware of
items that will be shared with others.Comment: 16 pages, 8 figures, 2 table

Multiphoton localization and propagating quantum gap solitons in a frequency gap medium
The many-particle spectrum of an isotropic frequency gap medium doped with
impurity resonance atoms is studied using the Bethe ansatz technique. The
spectrum is shown to contain pairs of quantum correlated ``gap excitations''
and their heavy bound complexes (``gap solitons''), enabling the propagation of
quantum information within the classically forbidden gap. In addition,
multiparticle localization of the radiation and the medium polarization occurs
when such a gap soliton is pinned to the impurity atom.Comment: 8 pages, RevTEX, to appear in Phys. Rev. Let
Three-dimensional femtosecond laser nanolithography of crystals
Nanostructuring hard optical crystals has so far been exclusively feasible at
their surface, as stress induced crack formation and propagation has rendered
high precision volume processes ineffective. We show that the inner chemical
etching reactivity of a crystal can be enhanced at the nanoscale by more than
five orders of magnitude by means of direct laser writing. The process allows
to produce cm-scale arbitrary three-dimensional nanostructures with 100 nm
feature sizes inside large crystals in absence of brittle fracture. To showcase
the unique potential of the technique, we fabricate photonic structures such as
sub-wavelength diffraction gratings and nanostructured optical waveguides
capable of sustaining sub-wavelength propagating modes inside yttrium aluminum
garnet crystals. This technique could enable the transfer of concepts from
nanophotonics to the fields of solid state lasers and crystal optics.Comment: Submitted Manuscript and Supplementary Informatio
Prawn fauna (Crustacea: Decapoda) of India - An annotated checklist of the Penaeoid, Sergestoid, Stenopodid and Caridean prawns
Twenty four species of Pandalid shrimps reported from the
Indian waters, of which six genera (Chlorotocella, Chlorotocus,
Chlorocurtis, Dorodotes, Heterocarpoides and Stylopandalus)
are represented by single species each. The genera, Plesionika
and Heterocarpus are represented by eleven and seven species
respectively. Plesionika adensameri (Balss, 1914) a deep-sea
shrimp hitherto unreported from Indian waters is recorded from
west coast of India. Information on some biological aspects of
few Pandalid shrimps from Indian waters is also reported in the
present paper
