Charmed Baryon Weak Decays with SU(3) Flavor Symmetry
We study the semileptonic and non-leptonic charmed baryon decays with
flavor symmetry, where the charmed baryons can be , , , or . With denoted as the baryon
octet (decuplet), we find that the
decays are forbidden, while the ,
, and decays are the only existing Cabibbo-allowed modes
for , , and , respectively. We predict the rarely studied
decays, such as and . For the observation, the doubly and triply charmed baryon decays of
, ,
, and are the favored Cabibbo-allowed decays,
which are accessible to the BESIII and LHCb experiments.Comment: 29 pages, no figure, a typo in the table correcte

SU(3) symmetry breaking in charmed baryon decays
We explore the breaking effects of the flavor symmetry in the singly
Cabibbo-suppressed anti-triplet charmed baryon decays of , with and the
baryon (pseudo-scalar) octets. We find that these breaking effects can be used
to account for the experimental data on the decay branching ratios of and =/. In addition, we
obtain that , and , which
all receive significant contributions from the breaking effects, and can be
tested by the BESIII and LHCb experiments.Comment: 12 pages, no figure, revised version accepted by EPJ
Effects of feeding organic and inorganic acid blends on growth performance and nutrient digestibility in young broiler chickens
One hundred and ninety-six Ross chicks with an initial body weight of 40.30±0.22g were used to study the effects of different crude protein levels supplemented with dietry organic and inorganic acids on growth performance and nutrient digestibility. The chicks were caged in pens of seven animals each, and had ad libitum access to feed and water. The chicks were divided into 4 groups: Control -22% crude protein basal diet; T1:22% crude protein basal diet + Organics™; T2:20% crude protein basal diet + Organics™; T3:18% crude protein basal diet + Orgacids™. The apparent digestibility of crude protein, calcium and phosphorus was calculated using Ti02. The birds fed with Control, T1 and T2 had better growth performance and feed conversion ratio than T3. The diets added with acidifiers had better digestibility of crude protein, phosphorus and calcium. In conclusion, the chickens fed with Control, T1 and T2 had better weight gain than 18% CP with acid blends. However, similar growth performance was found between Control, T1 and T2. T1 and T2 had lower FCR than Control and T3. Better growth performance in Control, T1 and T2 is mainly attributed to the better digestibility of nutrients such as crude protein, phosphorus and calcium. There was a reduction of 17% SBM used in the diet when Control diet was compared with T2 diet
Nonlinear Response of a Kondo system: Direct and Alternating Tunneling Currents
Non - equilibrium tunneling current of an Anderson impurity system subject to
both constant and alternating electric fields is studied. A time - dependent
Schrieffer - Wolff transformation maps the time - dependent Anderson
Hamiltonian onto a Kondo one. Perturbation expansion in powers of the Kondo
coupling strength is carried out up to third order, yielding a remarkably
simple analytical expression for the tunneling current. It is found that the
zero - bias anomaly is suppressed by an ac - field. Both dc and the first
harmonic are equally enhanced by the Kondo effect, while the higher harmonics
are relatively small. These results are shown to be valid also below the Kondo
temperature.Comment: 7 pages, RevTeX, 3 PS figures attached, the article has been
significantly developed: time - dependent Schrieffer - Wolff transformation
is presented in the full form, the results are applied to the change in the
direct current induced by an alternating field (2 figures are new
Unconventional Superconductivity in Heavy Fermion Systems
We review the studies on the emergent phases of superconductvity and
magnetism in the -electron derived heavy-fermion (HF) systems by means of
the nuclear-quadrupole-resonance (NQR) under pressure. These studies have
unraveled a rich variety of the phenomena in the ground state of HF systems. In
this article, we highlight the novel phase diagrams of magnetism and
unconventional superconductivity (SC) in CeCuSi, HF antiferromagnets
CeRhIn, and CeIn. A new light is shed on the difference and common
features on the interplay between magnetism and SC on the magnetic criticality.Comment: 15 pages, 13 figures, to appear in J. Phys. Soc. JPN, 74, No.1

Ultra-wide angle lens design with relative illumination analysis
An ultra-wide angle lens design with relative illumination analysis is presented. The half field angle of 80°, the relative illumination of the image plane will be reduced. It is necessary to increase the image numerical aperture ratio for X and Y direction, and decrease the angle between the chief ray and optical axis in the image space. However the ultra-wide angle lens induces great barrel distortion causing image extrusion. Therefore, we use F-theta distortion to replace optical distortion. Seven lenses and two pieces of flat glass are used for a sensor 1/6” sensor with 2.1 million pixels. The final result for the lens is a half viewing angle of 80°, F/2.4, a focal length 1.1 mm, a length of 22.37 mm, F-theta distortion of less than 2%, and relative illumination greater than 83%
