TL;DR: Results of an analysis of data from the Office for National Statistics Longitudinal Study for England and Wales suggest that conditions in residential area in early life may help to explain relatively poor health experience of populations in some parts of Britain today.

TL;DR: In this article, the role of wall crystals in ultrasonic refinement of pure magnesium and Mg-3Al-1Zn alloy was examined, where a titanium sonotrode was immersed into the melt for direct ultrasonication at an amplitude of 30 μm and a typical frequency of 20 kHz.

24 May 2010TL;DR: In this article, ARFIMAX models for the daily S&P500 log-returns are estimated, whereas the intraday prices comprise the dataset for an ARIMAX model.
Abstract: ARCH models for the daily S&P500 log-returns are estimated, whereas the intraday prices comprise the dataset for an ARFIMAX model. Model’s forecasting performance is statistically superior when the CBOE’s VIX index is incorporated as an explanatory variable.

TL;DR: The null result constrains the coalescence rate of monochromatic (delta function) distributions of nonspinning in primordial black hole binary formation scenario and strengthens the presently placed bounds from microlensing surveys of massive compact halo objects (MACHOs) provided by the MACHO and EROS Collaborations.
Abstract: We present a search for subsolar mass ultracompact objects in data obtained during Advanced LIGO’s second observing run. In contrast to a previous search of Advanced LIGO data from the first observing run, this search includes the effects of component spin on the gravitational waveform. We identify no viable gravitational-wave candidates consistent with subsolar mass ultracompact binaries with at least one component between 0.2 M⊙–1.0 M⊙. We use the null result to constrain the binary merger rate of (0.2 M⊙, 0.2 M⊙) binaries to be less than 3.7×105 Gpc-3 yr-1 and the binary merger rate of (1.0 M⊙, 1.0 M⊙) binaries to be less than 5.2×103 Gpc-3 yr-1. Subsolar mass ultracompact objects are not expected to form via known stellar evolution channels, though it has been suggested that primordial density fluctuations or particle dark matter with cooling mechanisms and/or nuclear interactions could form black holes with subsolar masses. Assuming a particular primordial black hole (PBH) formation model, we constrain a population of merging 0.2 M⊙ black holes to account for less than 16% of the dark matter density and a population of merging 1.0 M⊙ black holes to account for less than 2% of the dark matter density. We discuss how constraints on the merger rate and dark matter fraction may be extended to arbitrary black hole population models that predict subsolar mass binaries.
