Generating entanglement between quantum dots with different resonant frequencies based on Dipole Induced Transparency
We describe a method for generating entanglement between two spatially
separated dipoles coupled to optical micro-cavities.
The protocol works even when the dipoles have different resonant frequencies
and radiative lifetimes.
This method is particularly important for solid-state emitters, such as
quantum dots, which suffer from large inhomogeneous broadening. We show that
high fidelities can be obtained over a large dipole detuning range without
significant loss of efficiency. We analyze the impact of higher order photon
number states and cavity resonance mismatch on the performance of the protocol

Relationships between hemoglobin A1c and spot glucose measurements in Nigerians with type 2 diabetes mellitus
Background: Glycosylated hemoglobin, HbA1c is the most acceptable measure of chronic glycemia. It is not widely available and/or affordable in Nigeria. The mean of the monthly fasting plasma glucose (MFPG) of the preceding 3 months is often used as surrogate for assessing chronic glycemia. Objective: To determine the relationships among fasting plasma glucose (FPG), 2‑hour post‑prandial glucose (2‑hPG), HbA1c, and MFPG. Materials and Methods: Hospital records were used to derive the MFPGs of diabetic subjects from the mean of their monthly FPGs of the preceding three months. Other data extracted included the patient’s age, sex, body mass index (BMI), waist circumference (WC), and duration of diabetes mellitus (DMDU). FPG, 2‑ hPG and HbA1c were determined during this index consultation. Results: Ninety five persons (65 males, 30 females) with type 2 were included in the study. Their mean age and DMDU were 54.7 ± 8.9 years and 8.1 ± 6.1 years, respectively. Their mean WC, BMI, FPG, 2‑hPG, HbA1c, and MFPG were 100.2 ± 11.0 cm, 24.2 ± 4.3 kgm/2, 7.5 ± 2.4 mmol/l, 10.4 ± 4.1 mmol/l, 8.2 ± 2.2%, and 5.9 ± 2.2 mmol/l, respectively. The males were significantly older (57.5 ± 8.4 vs 49.3 ± 7.6, P<0.001) while the females had higher waist circumference and BMI than their male counterparts: 104.8 ± 11.6 cm vs 92.8 ± 10.1 cm, P<0.004; and 25.8 ± 4.9 kg/m2 vs 23.3 ± 3.7 kg/m2, P<0.005, respectively. There were no significant differences in FPG, 2‑hPG, MFPG and HbA1c levels between male and female subjects. There were significant positive correlations between FPG and HbA1c (r=0.45, P=0.05) and between 2‑hPG and HbA1c (r=0.52, P=0.01), but there was no positive correlation between MFPG and HbA1c (r=−0.20, P=0.18). Conclusion: There is no positive correlation between MFPG and HbA1c and thus MFPG may not be a good surrogate for HbA1c in assessment of chronic glycemia in our patients.Keywords: Diabetes mellitus, fasting plasma glucose, glycosylated hemoglobin (HbA1c), 2‑h post‑prandial glucoseNigerian Journal of Clinical Practice • Jan-Mar 2012 • Vol 15 • Issue

The superluminous supernova SN 2017egm in the nearby galaxy NGC 3191: a metal-rich environment can support a typical SLSN evolution
At redshift z=0.03, the recently-discovered SN 2017egm is the nearest Type I
superluminous supernova (SLSN) to date, and first near the center of a massive
spiral galaxy (NGC 3191). Using SDSS spectra of NGC 3191, we find a metallicity
~2 Z at the nucleus and ~1.3 Z for a star forming region at a
radial offset similar to SN 2017egm. Archival radio-to-UV photometry reveals a
star-formation rate ~15 M yr (with ~70% dust-obscured), which
can account for a Swift X-ray detection, and stellar mass ~
M. We model the early UV-optical light curves with a magnetar
central-engine model, using the Bayesian light curve fitting tool MOSFiT. The
fits indicate ejecta mass 2-4 M, spin period 4-6 ms, magnetic field
(0.7-1.7)G, and kinetic energy 1-2 erg. These
parameters are consistent with the overall distributions for SLSNe, modeled by
Nicholl et al (2017), although the derived mass and spin are towards the low
end, possibly indicating enhanced loss of mass and angular momentum before
explosion. This has two implications: (i) SLSNe can occur at solar metallicity,
although with a low fraction ~10%; and (ii) metallicity has at most a modest
effect on their properties. Both conclusions are in line with results for long
gamma-ray bursts. Assuming a monotonic rise gives an explosion date MJD
. However, a short-lived excess in the data relative to the
best-fitting models may indicate an early-time `bump'. If confirmed, SN 2017egm
would be the first SLSN with a spectrum during the bump-phase; this shows the
same O II lines seen at maximum light, which may be an important clue for
explaining these bumps.Comment: Accepted for publication in ApJ
Measuring the delay time distribution of binary neutron stars. II. Using the redshift distribution from third-generation gravitational wave detectors network
We investigate the ability of current and third-generation gravitational wave
(GW) detectors to determine the delay time distribution (DTD) of binary neutron
stars (BNS) through a direct measurement of the BNS merger rate as a function
of redshift. We assume that the DTD follows a power law distribution with a
slope and a minimum merger time , and also allow the
overall BNS formation efficiency per unit stellar mass to vary. By convolving
the DTD and mass efficiency with the cosmic star formation history, and then
with the GW detector capabilities, we explore two relevant regimes. First, for
the current generation of GW detectors, which are only sensitive to the local
universe, but can lead to precise redshift determinations via the
identification of electromagnetic counterparts and host galaxies, we show that
the DTD parameters are strongly degenerate with the unknown mass efficiency and
therefore cannot be determined uniquely. Second, for third-generation detectors
such as Einstein Telescope (ET) and Cosmic Explorer (CE), which will detect BNS
mergers at cosmological distances, but with a redshift uncertainty inherent to
GW-only detections (), we show that the DTD and mass
efficiency can be well-constrained to better than 10\% with a year of
observations. This long-term approach to determining the DTD through a direct
mapping of the BNS merger redshift distribution will be supplemented by more
near term studies of the DTD through the properties of BNS merger host galaxies
at (Safarzadeh & Berger 2019).Comment: 10 pages, Accepted to ApJ Letter
