Holographic Mutual Information of Two Disjoint Spheres
We study quantum corrections to holographic mutual information for two
disjoint spheres at a large separation by using the operator product expansion
of the twist field. In the large separation limit, the holographic mutual
information is vanishing at the semiclassical order, but receive quantum
corrections from the fluctuations. We show that the leading contributions from
the quantum fluctuations take universal forms as suggested from the boundary
CFT. We find the universal behavior for the scalar, the vector, the tensor and
the fermionic fields by treating these fields as free fields propagating in the
fixed background and by using the 1/n prescription. In particular, for the
fields with gauge symmetries, including the massless vector boson and massless
graviton, we find that the gauge parts in the propagators play indispensable
role in reading the leading order corrections to the bulk mutual information.Comment: 37 pages, 1 figure; significant revisions, corrected the discussions

Modeling the JWST high-redshift galaxies with a general formation scenario and the consistency with the CDM model
Early results from the James Webb Space Telescope (JWST) observations have
hinted at two traces beyond the standard cosmological framework. One is the
extraordinarily high stellar masses and their density at ,
another is the unexpected abundance of ultra-violet (UV) bright galaxies at
. Nevertheless, both pieces of evidence are not statistically robust,
yet. In this work, we construct rest-frame UV luminosity functions (LFs) based
on a general formation model for these high-redshift galaxy candidates, since
UV LFs always carry the information of stellar formation efficiency (SFE),
initial mass function (IMF), dust attenuation, and other crucial elements for
galaxy evolution. By updating the massive galaxies candidates with
spectroscopic observations and exploring the parameter space of SFE, we are
able to reasonably explain the cumulative stellar mass density within the
redshift range of , with only one galaxy exhibiting unusual
characteristics. We also reveal a potential non-monotonic trend of SFE with the
increasing redshift. At higher redshift (), bright UV LFs can be well
fitted with non-dust attenuation or Top-heavy IMF for Population III stars. The
Population III star scenario can also naturally account for the possible dip of
SFE at .Comment: 9 pages, 4 figures, and 1 tabl

In the title compound, C15H18ClNO4S·H2O, the thiazolidine ring displays a half-chair conformation. In the crystal, the water molecules are linked to the organic acid molecules via intermolecular O—H⋯O hydrogen bonds
Weak Solutions for Nonlinear Fractional Differential Equations in Banach Spaces
We discuss the existence of weak solutions for a nonlinear boundary value problem of fractional differential equations in Banach space. Our analysis relies on the Mönch's fixed point theorem combined with the technique of measures of weak noncompactness
Scalar products of the open XYZ chain with non-diagonal boundary terms
With the help of the F-basis provided by the Drinfeld twist or factorizing
F-matrix of the eight-vertex solid-on-solid (SOS) model, we obtain the
determinant representations of the scalar products of Bethe states for the open
XYZ chain with non-diagonal boundary terms. By taking the on shell limit, we
obtain the determinant representations (or Gaudin formula) of the norms of the
Bethe states.Comment: Latex file, 28 page
Comparison of Endocrine Profile and In Vitro Fertilization Outcome in Patients with PCOS, Ovulatory PCO, or Normal Ovaries
Aim. To compare the basic endocrine profile and outcomes of in vitro fertilization (IVF) in women with polycystic ovary syndrome (PCOS), ovulatory polycystic ovaries (PCO), or normal ovaries (NO). Methods. The basic clinical features and in vitro fertilization and embryo transfer outcome in patients receiving IVF or intracytoplasmic sperm injection (ICSI) were retrospectively analyzed. Results. The body mass index, basal luteinizing hormone, and testosterone levels were significantly lower in patients with ovulatory PCO compared to those in patients with PCOS. The PCOS patients exhibited the shortest duration of ovarian stimulation and lowest dose of gonadotropin, followed by the ovulatory PCO and NO patients. The ovulatory PCO and PCOS patients showed similar levels of E2 on the human chorionic gonadotropin treatment day and numbers of oocytes, which were both significantly higher than those of the NO patients. The fertilization rate of the PCOS patients was significantly lower than the other two groups. Compared to NO patients, the cleavage rate was lower in both PCOS and ovulatory PCO patients, however, the number of available embryos was significantly more in these two groups. The incidence of the moderate to severe ovarian hyperstimulation syndrome (OHSS) was markedly higher in the PCOS and ovulatory PCO patients. Conclusion. Ovulatory PCO patients do not express similar endocrine abnormalities as PCOS patients. Although the fertilization rate and cleavage rate were relatively low in PCOS patients, ultimately, all the three groups showed similar transferred embryo numbers, clinical pregnancy rates, and implantation rates. Since the incidence of OHSS was much higher in the PCOS and ovulatory PCO patients, we should take more care of these patients and try to prevent severe OHSS
