Information-flow analysis is a powerful technique for reasoning about the sensitive information exposed by a program during its execution. We present the first automatic method for information-flow ...analysis that discovers what information is leaked and computes its comprehensive quantitative interpretation. The leaked information is characterized by an equivalence relation on secret artifacts, and is represented by a logical assertion over the corresponding program variables. Our measurement procedure computes the number of discovered equivalence classes and their sizes. This provides a basis for computing a set of quantitative properties, which includes all established information-theoretic measures in quantitative information-flow. Our method exploits an inherent connection between formal models of qualitative information-flow and program verification techniques. We provide an implementation of our method that builds upon existing tools for program verification and information-theoretic analysis. Our experimental evaluation indicates the practical applicability of the presented method.
The spin density matrix of the has been determined for the reaction with unpolarized in-flight data measured by the Crystal Barrel LEAR experiment at CERN. The two main decay modes of the into and ...Formula omitted have been separately analyzed for various Formula omittedmomenta between 600 and 1940 MeV/c. The results obtained with the usual method by extracting the matrix elements via the Formula omitted decay angular distributions and with the more sophisticated method via a full partial wave analysis are in good agreement. A strong spin alignment of the is clearly visible in this energy regime and all individual spin density matrix elements exhibit an oscillatory dependence on the production angle. In addition, the largest contributing orbital angular momentum of the system has been identified for the different beam momenta. It increases from 2 at 600 MeV/c to 5 at 1940 MeV/c.
About 40% of patients with advanced cancer develop metastases in the central nervous system (CNS), mainly from primary tumors of lung, breast and melanoma. In most of cases there are multiple CNS ...metastases, making surgery or localized radiosurgery not feasible. The current standard of care for these patients is radiation therapy, which can improve neurologic symptoms but does not have any impact on the patient's overall survival. Temozolomide, capecitabine and gefitinib are safe and active in the treatment of CNS metastases from melanoma/recurrent gliomas, breast carcinoma and lung cancer, respectively. New, orally administered drugs hold a great potential for patients with CNS metastases.
A new highly modular and generic Partial Wave Analysis (PWA) software package including a general framework for future hadron spectroscopy experiments like PANDA is currently under development. The ...aims and present status of the software package are summarized and the first PWA results obtained with the already existing tools are presented. These analyses are mainly focused on important aspects of antiproton proton annihilation processes with relevance for the PANDA experiment. For this purpose Crystal Barrel LEAR data are currently under investigation in order to gain a deeper insight to the production mechanisms of vector mesons. In addition analyses for the identification of resonances in radiative

Properties of the Roper resonance, the first scalar excitation of the nucleon, are determined. Pole positions and residues of the P11 partial wave are studied in a combined analysis of pion- and ...photo-induced reactions. We find the Roper pole at {(1371±7)−i(92±10)} MeV and an elasticity of 0.61±0.03. The largest decay coupling is found for the Nσ (σ=(ππ)-S-wave). The analysis is based on new data on γp→pπ0π0 for photons in the energy range from the two-pion threshold to 820 MeV from TAPS at Mainz and from 0.4 to 1.3 GeV from Crystal Barrel at Bonn and includes further data from other experiments. The partial wave analysis excludes the possibility that the Roper resonance is split into two states with different partial decay widths.
We show that the amount of information about the key that an unknown-message attacker can extract from a deterministic side-channel is bounded from above by |O| log 2 (n + 1) bits, where n is the ...number of side-channel measurements and O is the set of possible observations. We use this bound to derive a novel countermeasure against timing attacks, where the strength of the security guarantee can be freely traded for the resulting performance penalty. We give algorithms that efficiently and optimally adjust this trade-off for given constraints on the side-channel leakage or on the efficiency of the cryptosystem. Finally, we perform a case-study that shows that applying our countermeasure leads to implementations with minor performance overhead and formal security guarantees.
