The Transitivity of Trust Problem in the Interaction of Android Applications
Mobile phones have developed into complex platforms with large numbers of
installed applications and a wide range of sensitive data. Application security
policies limit the permissions of each installed application. As applications
may interact, restricting single applications may create a false sense of
security for the end users while data may still leave the mobile phone through
other applications. Instead, the information flow needs to be policed for the
composite system of applications in a transparent and usable manner. In this
paper, we propose to employ static analysis based on the software architecture
and focused data flow analysis to scalably detect information flows between
components. Specifically, we aim to reveal transitivity of trust problems in
multi-component mobile platforms. We demonstrate the feasibility of our
approach with Android applications, although the generalization of the analysis
to similar composition-based architectures, such as Service-oriented
Architecture, can also be explored in the future
Dikvarkovi kao efektivne čestice u tvrdom ekskluzivnom raspršenju
In the context of hard hadronic reactions, diquarks are a useful phenomenological device to model non-perturbative effects still observable in the kinematic range accessible by present-day experiments. In the following, we present diquark-model predictions for γγ → p¯p and ΛΛ. We also sketch how the (pure quark) hard-scattering formalism for exclusive reactions involving baryons can be reformulated in terms of quarks and diquarks. As an application of these considerations, we analyze the magnetic proton form factor with regard to its quark-diquark content.Dikvarkovi su pogodna fenomenološka zamisao u razmatranju tvrdih hadronskih reakcija za modeliranje neperturbativnih efekata koji se opažaju u današnjim mjerenjima dostupnom kinematičkom području. Prikazuju se predviđanja dikvarkovskog modela za γγ → pp¯ i ΛΛ. Opisuje se kako se formalizam (čisto kvarkovskog) tvrdog raspršenja koja uključuju barione može prikazati pomoću kvarkova i dikvarkova. U primjeni tih razmatranja analizira se magnetski faktor oblika protona za sadržaj kvarkova i dikvarkova u protonu

Midrapidity phi production in Au+Au collisions at sqrt[sNN]=130 GeV
We present the first measurement of midrapidity vector meson phi production in Au+Au collisions at RHIC (sqrt[sNN]=130 GeV) from the STAR detector. For the 11% highest multiplicity collisions, the slope parameter from an exponential fit to the transverse mass distribution is T=379±50(stat)±45(syst) MeV, the yield dN/dy=5.73±0.37(stat)±0.69(syst) per event, and the ratio N phi /Nh- is found to be 0.021±0.001(stat)±0.004(syst). The measured ratio N phi /Nh- and T for the phi meson at midrapidity do not change for the selected multiplicity bins.alle Autoren: C. Adler11, Z. Ahammed23, C. Allgower12, J. Amonett14, B. D.
