Parylene membrane slot filter for the capture, analysis and culture of viable circulating tumor cells
This paper presents a method of capturing viable
circulating tumor cells (CTC) from human whole
blood using constant-pressure-driven filtration through
a specially designed parylene-C membrane “slot” filter.
More than 90% viable cancer cells could be recovered
from whole blood using the slot filter, with minimal
non-cancer blood cells left on the filter. The feasibility
of the telomerase activity measurement of a single
cancer cell taken from the filter after capture was
proven. The on-filter and off-filter cultures of the
captured cancer cells were also demonstrated
Bis(2-aminopyrimidine-κN 1)diaquadinitrato-κO;κ2 O,O′-cadmium(II) monohydrate
In the title compound, [Cd(NO3)2(C4H5N3)2(H2O)2]·H2O, the Cd atom is seven-coordinated by two 2-aminopyrimidine molecules, two water molecules, one bidentate nitrate anion and one monodentate nitrate anion. A network of N—H⋯O, N—H⋯N and O—H⋯O hydrogen bonds helps to consolidate the crystal structure
Study on muon anomalous magnetic dipole moment in BLMSSM via the mass insertion approximation
There are 4.2 deviations between the updated experimental results of
muon anomalous magnetic dipole moment (MDM) and the corresponding theoretical
prediction of the Standard Model (SM). We calculate the muon MDM in the
framework of the MSSM extension with local gauged baryon and lepton numbers
(BLMSSM). In this paper, we discuss how the muon MDM depends on the parameters
in the BLMSSM in detail within the mass insertion approximation. Among the many
parameters, , , and are more
sensitive parameters. Considering the experimental limitations, our best
numerical result of is around , which can
well compensate the departure between the experiment data and SM prediction
Study lepton flavor violation within the Mass Insertion Approximation
We study lepton flavor violating (LFV) decays
(,
and ) in the SSM,
which is the extension of the minimal supersymmetric standard
model(MSSM). The local gauge group of SSM is . These processes are strictly forbidden in the
standard model(SM), but these LFV decays are a signal of new physics(NP). We
use the Mass Insertion Approximation(MIA) to find sensitive parameters that
directly influence the result of the branching ratio of LFV decay
. Combined with the latest experimental
results, we analyze the relationship between different sensitive parameters and
the branching ratios of the three processes. According to the numerical
analysis, we can conclude that the main sensitive parameters and LFV sources
are the non-diagonal terms of the slepton mass matrix
Near tip strain evolution under cyclic loading
The concept of ratchetting strain as a crack driving force in controlling crack growth has previouslybeen explored at Portsmouth using numerical approaches for nickel-based superalloys. In this paper, we reportthe first experimental observations of the near-tip strain evolution as captured by the Digital Image Correlation(DIC) technique on a compact tension specimen of stainless steel 316L. The evolution of the near-tip strainswith loading cycles was studied whilst the crack tip was maintained stationary. The strains were monitored overthe selected distances from the crack tip for a given number of cycles under an incremental loading regime. Theresults show that strain ratchetting does occur with load cycling, and is particularly evident close to the crack tipand under higher loads. A finite element model has been developed to simulate the experiments and thesimulation results are compared with the DIC measurements
mixing in the SSM
SSM is a non-universal Abelian extension of the Minimal
Supersymmetric Standard Model (MSSM) and its local gauge group is extended to
. Based on the latest data of
neutral meson mixing and experimental limitations, we investigate the process
of mixing in SSM. Using the effective Hamiltonian
method, the Wilson coefficients and mass difference are
derived. The abundant numerical results verify that
and
are sensitive parameters to the process of mixing. With
further measurement in the experiment, the parameter space of the SSM
will be further constrained during the mixing process of
Lepton flavor violating decays
In this paper, we study the lepton flavor violating decays of the
(j=2, 3; i=1, 2) processes under the
SSM. The SSM is the addition of three singlet new Higgs
superfields and right-handed neutrinos to the minimal supersymmetric standard
model (MSSM). Based on the latest experimental constraints of , we analyze the effects of different sensitive parameters on
the results and made reasonable predictions for future experimental
development. Numerical analysis shows that many parameters have a greater or
lesser effect on lepton flavor violation(LFV), but the main sensitive
parameters and sources leading to LFV are the non-diagonal elements involving
the initial and final leptons. This work could provide a basis for the
discovery of the existence of new physics (NP)
