Safety and efficacy of vismodegib in patients aged ≥65 years with advanced basal cell carcinoma.
Because many patients with unresectable basal cell carcinoma (BCC) are aged ≥65 years, this study explores the efficacy and safety of vismodegib in these patients with locally advanced (la) or metastatic (m) basal cell carcinoma (BCC) in the ERIVANCE BCC trial and the expanded access study (EAS).We compared patients aged ≥65 years to patients aged <65 years taking vismodegib 150 mg/day, using descriptive statistics for response and safety. Patients aged ≥65 years (laBCC/mBCC) were enrolled in ERIVANCE BCC (33/14) and EAS (27/26). Investigator-assessed best overall response rate in patients ≥65 and <65 years was 46.7%/35.7% and 72.7%/52.6% (laBCC/mBCC), respectively, in ERIVANCE BCC and 45.8%/33.3% and 46.9%/28.6%, respectively, in EAS. These differences were not clinically meaningful. Safety was similar in both groups, although those aged ≥65 years had a higher percentage of grade 3-5 adverse events than those aged <65 years. Vismodegib demonstrated similar clinical activity and adverse events regardless of age
Decays of and into vector and pseudoscalar meson and the pseudoscalar glueball- mixing
We introduce a parametrization scheme for where
the effects of SU(3) flavor symmetry breaking and doubly OZI-rule violation
(DOZI) can be parametrized by certain parameters with explicit physical
interpretations. This scheme can be used to clarify the glueball-
mixing within the pseudoscalar mesons. We also include the contributions from
the electromagnetic (EM) decays of and via
. Via study of the isospin violated
channels, such as , ,
and , reasonable constraints on the EM decay
contributions are obtained. With the up-to-date experimental data for
, and , etc, we arrive at a consistent description of the mentioned
processes with a minimal set of parameters. As a consequence, we find that
there exists an overall suppression of the form factors,
which sheds some light on the long-standing " puzzle". By determining
the glueball components inside the pseudoscalar and in
three different glueball- mixing schemes, we deduce that the lowest
pseudoscalar glueball, if exists, has rather small component, and it
makes the a preferable candidate for glueball.Comment: Revised version to appear on J. Phys. G; An error in the code was
corrected. There's slight change to the numerical results, while the
conclusion is intac
What determines pension insurance participation in China?: triangulation and the intertwined relationship among employers, employees and the government
The current study draws on the Advocacy Coalition Framework to examine what determines employees’ pension participation in China. For the purpose of exploring which employees actually receive pension coverage and why, econometric analysis was conducted with China’s Employer–Employee Matched Survey data (N = 3412). A variety of both individual factors, ranging from age and Hukou status to job characteristics, and macro factors, including interprovincial migration and level of economic development, are all found to predict insurance coverage. Qualitative research results contextualize these findings by discussing the often ambivalent and triangulated relations among employers, employees and government. These three groups primarily use shared core policy beliefs to structure their interactions in the form of advocacy coalitions. Various types of cross-coalition interaction, including negotiation, cooperation and conflict, are examined. These findings carry both theoretical and policy implications
Measuring psi(3770) -> Kshort Klong as a test of the S- and D-wave mixing of charmonia
Adding to the long standing "rho-pi puzzle" in psi(3686) and J/psi decays,
recently BES reported the branching ratio of psi(3686) -> Kshort Klong which is
enhanced relative to the pQCD " 12% rule" expectation from the branching ratio
of J/psi -> Kshort Klong. If the enhancement is due to the mixing of the S- and
D-wave charmonium states as in the rho-pi case, the newly measured branching
ratio of psi(3686) -> Kshort Klong gives a constraint on the psi(3770) ->
Kshort Klong. It serves as a good test for the scenario of the S- and D-wave
mixing in the psi(3686) and psi(3770).Comment: 4 pages, 1 figur
Secure State Estimation against Sparse Attacks on a Time-varying Set of Sensors
This paper studies the problem of secure state estimation of a linear
time-invariant (LTI) system with bounded noise in the presence of sparse
attacks on an unknown, time-varying set of sensors. In other words, at each
time, the attacker has the freedom to choose an arbitrary set of no more that
sensors and manipulate their measurements without restraint. To this end,
we propose a secure state estimation scheme and guarantee a bounded estimation
error subject to -sparse observability and a mild, technical assumption
that the system matrix has no degenerate eigenvalues. The proposed scheme
comprises a design of decentralized observer for each sensor based on the local
observable subspace decomposition. At each time step, the local estimates of
sensors are fused by solving an optimization problem to obtain a secure
estimation, which is then followed by a local detection-and-resetting process
of the decentralized observers. The estimation error is shown to be
upper-bounded by a constant which is determined only by the system parameters
and noise magnitudes. Moreover, we optimize the detector threshold to ensure
that the benign sensors do not trigger the detector. The efficacy of the
proposed algorithm is demonstrated by its application on a benchmark example of
IEEE 14-bus system
A Model of Cooperative Threads
We develop a model of concurrent imperative programming with threads. We
focus on a small imperative language with cooperative threads which execute
without interruption until they terminate or explicitly yield control. We
define and study a trace-based denotational semantics for this language; this
semantics is fully abstract but mathematically elementary. We also give an
equational theory for the computational effects that underlie the language,
including thread spawning. We then analyze threads in terms of the free algebra
monad for this theory.Comment: 39 pages, 5 figure
The interference between virtual photon and 1-- charmonium in e+e-experiment
e+e- Experiments producing charmonium are reviewed. It is found that the
contribution of the continuum amplitude via virtual photon was neglected in
almost all the experiments and the channels analyzed. It is shown that the
contribution of the continuum part may affect the final results significantly
in psi(2S) and psi(3770) decays, while the interference between continuum and
resonance amplitudes may even affect the J/psi decays as well as the psi(2S)
and psi(3770). This should be considered in analyzing the "rho-pi puzzle"
between J/psi and psi(2s) decays, and the difference between inclusive hadron
and DDbar cross sections in psi(3770) decays.Comment: 6 pages, 2 figure
