Hipparcos photometric data for the massive O-type binary UW CMa were analysed within the framework of the Roche model. Photometric solutions were obtained for five mass ratios in the $q=M_2/M_1=0.5-1.5$ range. The system is found to be in a contact configuration. Independently of $q$, the best-fitting model solutions correspond to the orbital inclination $i \sim 71^\circ$ and the temperature of the secondary component $T_2 \sim 33500\,K$, at the fixed temperature of the primary $T_1=33750 K$. Considering that the spectrum of the secondary is very weak, photometric solutions corresponding to the contact configuration favor the mass ratio $q$ smaller than unity (in which case the luminosity of the secondary is smaller than that of the primary). The absolute parameters of the system are estimated for different values of the mass ratio.

Twenty eclipsing binaries were selected for an analysis from a huge database of observations made by the INTEGRAL/OMC camera. The photometric data were processed and analyzed, resulting in a first light-curve study of these neglected eclipsing binaries. Most of the selected systems are the detached ones. The system ET Vel was discovered to be an eccentric one. Due to missing spectroscopic study of these stars, further detailed analyses are still needed.

Twenty-one eclipsing binaries were selected for an analysis from a huge database of observations made by the INTEGRAL/OMC camera. The photometric data were processed and analyzed, resulting in a first light-curve study of these neglected eclipsing binaries. In several systems from this sample even their orbital periods have been confirmed or modified. Thirty-two new minima times of these binaries have been derived.

We describe a stream-based analysis pipeline to detect gravitational waves from the merger of binary neutron stars, binary black holes, and neutron-star-black-hole binaries within ~ 1 minute of the arrival of the merger signal at Earth. Such low-latency detection is crucial for the prompt response by electromagnetic facilities in order to observe any fading electromagnetic counterparts that might be produced by mergers involving at least one neutron star. Even for systems expected not to produce counterparts, low-latency analysis of the data is useful for deciding when not to point telescopes, and as feedback to observatory operations. Analysts using this pipeline were the first to identify GW151226, the second gravitational-wave event ever detected. The pipeline also operates in an offline mode, in which it incorporates more refined information about data quality and employs acausal methods that are inapplicable to the online mode. The pipeline's offline mode was used in the detection of the first two gravitational-wave events, GW150914 and GW151226, as well as the identification of a third candidate, LVT151012.

The likelihood function represents statistical evidence in the context of data and a probability model. Considerable theory has demonstrated that evidence strength for different parameter values can be interpreted from the ratio of likelihoods at different points on the likelihood curve. The likelihood function can, however, be unknown or difficult to compute; e.g. for genetic association studies with a binary outcome in large multi-generational families. Composite likelihood is a convenient alternative to using the real likelihood and here we show composite likelihoods have valid evidential interpretation. We show that composite likelihoods, with a robust adjustment, have two large sample performance properties that enable reliable evaluation of relative evidence for different values on the likelihood curve: (1) The composite likelihood function will support the true value over the false value by an arbitrarily large factor; and (2) the probability of favouring a false value over a true value with high probability is small and bounded. Using an extensive simulation study, and in a genetic association analysis of reading disability in large complex pedigrees, we show that the composite approach yields valid statistical inference. Results are compared to analyses using generalized estimating equations and show similar inference is obtained, although the composite approach results in a full likelihood solution that provides additional complementary information.

We study the anisotropies of the Galactic confusion noise background and its effects on LISA data analysis. LISA has two data streams of the gravitational waves signals relevant for low frequency regime. Due to the anisotropies of the background, the matrix for their confusion noises has off-diagonal components and depends strongly on the orientation of the detector plane. We find that the sky-averaged confusion noise level $\sqrt {S(f)}$ could change by a factor of 2 in three months, and would be minimum when the orbital position of LISA is either around the spring or autumn equinox.

When a missing-data mechanism is NMAR or non-ignorable, missingness is itself vital information and it must be taken into the likelihood, which, however, needs to introduce additional parameters to be estimated. The incompleteness of the data and introduction of more parameters can cause the identification problem. When a response variable is binary, it becomes a more serious problem because of less information of bi- nary data, however, there are no methods to briefly verify whether a mode is identified or not. Therefore, we provide a new necessary and sufficient condition to easily check model identifiability when analyzing binary data with non-ignorable missing by condi- tional models. This condition can give us what condition is needed for a model to have identifiability as well as make easily check the identifiability of a model.

We have completed a 350 MHz drift scan survey using the Robert C. Byrd Green Bank Telescope with the goal of finding new radio pulsars, especially millisecond pulsars that can be timed to high precision. This survey covered ~10300 square degrees and all of the data have now been fully processed. We have discovered a total of 31 new pulsars, seven of which are recycled pulsars. A companion paper by Boyles et al. (2012) describes the survey strategy, sky coverage, and instrumental set-up, and presents timing solutions for the first 13 pulsars. Here we describe the data analysis pipeline, survey sensitivity, and follow-up observations of new pulsars, and present timing solutions for 10 other pulsars. We highlight several sources---two interesting nulling pulsars, an isolated millisecond pulsar with a measurement of proper motion, and a partially recycled pulsar, PSR J0348+0432, which has a white dwarf companion in a relativistic orbit. PSR J0348+0432 will enable unprecedented tests of theories of gravity.

This study compared two statistical approaches, predictive discriminant function analysis and binary logistic regression analysis, to determine the characteristics of at-risk students who succeeded in comparison with those who did not succeed in a project-based alternative high school program. The study also investigated true positive hit rates for predicting correctly the students that would be successful using each statistical approach to provide information for decision making in admissions decisions for this program. Data came from the Wisconsin Youth Survey from measures of bonding with teachers, school, and peers and from a measure of educational engagement completed by 70 students. Other variables measured were family composition, student employment, grade, gender, and age. The predictive discriminant analysis approach produced a true positive hit rate of 79% compared to the remarkable 94% of the binary logistic approach. Advantages of the binary logistic approach are discussed. (SLD)

This article is from Statistics in Medicine , volume 32 . Abstract The process of undertaking a meta-analysis involves a sequence of decisions, one of which is deciding which measure of treatment effect to use. In particular, for comparative binary data from randomised controlled trials, a wide variety of measures are available such as the odds ratio and the risk difference. It is often of interest to know whether important conclusions would have been substantively different if an alternative measure had been used. Here we develop a new type of sensitivity analysis that incorporates standard measures of treatment effect. Thus, rather than examining the implications of a variety of measures in an ad hoc manner, we can simultaneously examine an entire family of possibilities, including the odds ratio, the arcsine difference and the risk difference.

2Brownies and Prince Florimel

By Palmer Cox

After Prince Florimel flees his home (and a particularly nasty uncle) he has a series of adventures with the mischevious but helpful Brownies, Queen Titania and her fairies, and the ill-tempered enchanter, Dragonfel.<p> Reader's note: Although some terms in this 1918 book are not really acceptable anymore, the book’s overall message that people should not be judged by their size is still a worthy lesson today. - Summary by Jude Somers

The Crusades were a series of religious wars fought between 1096 and 1272 to recover the Holy Land from Islamic rule. According to the Latin Church, Crusaders were penitent pilgrims whose sins were forgiven. British historian, George Cox, writes of the churchmen, great and small, who inspired the Crusades, of the warriors who left families and lands behind, of the wily Venetian merchants and Byzantine emperors who exploited the knights, and of the valor of the Saracens. Here are accounts of sublime sacrifice and bestial ferocity, of dynastic conflict within the Crusader States, of sieges, starvation, pestilence, and ambush, and of the clash and interpenetration of two cultures. - Summary by Pamela Nagami, M.D.

The Brownies are delightful, helpful, mischievous characters and this series of rollicking rhymes tells many stories about their adventures. - Summary by Jude Somers

5Another Brownie Book

By Palmer Cox

Brownies, like fairies and goblins, are imaginary little sprites, who are supposed to delight in harmless pranks and helpful deeds. They work and sport while weary households sleep, and never allow themselves to be seen by mortal eyes. Summary by Palmer Cox

6Frontier Humor in Verse, Prose and Picture

By Palmer Cox

Also known for his "Brownies" books, Canadian humorist Palmer Cox give us a delightful collection of humorous verse and short prose vignettes. From the publisher's preface, "thrice happy is the man who, having seen, can tell the fun; and having told, can picture it for others’ eyes and so roll on the rollicking humor, for the brightening of a world already far too sad." - Summary by Larry Wilson

A limbless reptilian monster that propels itself through the swamps with a propellor-tipped tail? A creature so ashamed of its monstrous appearance that it dissolves into tears when captured? Learn about the snoligoster, the squonk and many other 'fearsome critters' in this field guide written and illustrated by two North American foresters who know them well. Listeners who suspect that these creatures are the stuff of tall tales, will nevertheless do well to look out for slide-rock bolters when vacationing in the Colorado mountains. - Summary by Phil Benson

The British historian, George W. Cox writes that the "whole duration of the Athenian empire extends over little more than two generations." This confederation of Greek city states with Athens at its head was an attempt to present a unified front to the Persian Empire. But ultimately, the strife between democratic and oligarchic factions within each polis, combined with the tangle of alliances between the various city states, led to the ruinous and protracted Peloponnesian War. In this short work, Cox describes the battles on land and sea, and such personalities as the Athenian general, Nikias, his Spartan counterpart, Agis, and, above all, unprincipled, charismatic Alcibiades. (Summary by Pamela Nagami, M.D.)

In the darkest days of the Persian War when the armies of Xerxes were overrunning northern Greece, Athens faced destruction. The desperate Athenians consulted the oracle at Delphi, who answered, "For thus saith Zeus, that when all else within the land of Cecrops is wasted, the wooden wall alone shall not be taken." The British historian, George Cox agrees with many other authorities that the Greek statesman, Themistocles, bribed the oracle. Realizing that their survival depended upon a strong navy, he declared that the prophesy meant that the Persians would be defeated, not by fortifying Athens, but by "the fight at sea, for the fleet is your wooden wall." This book is a short history of the founding fathers of Athens, its lawgivers, tyrants, and generals: Solon, Peisistratos, Kleisthenes, Miltiades, Aristeides, and, above all, Themistocles.

The object of this little book is to bring the reader nearer to the great masters in the realm of music, and make him or her acquainted with the man who worked, played, and suffered as do other men. Though confining themselves to a simple style, the authors have tried to enter into the life of each composer, and, wherever possible, by means of earnest study of letters and other data which have come down to us, to copy that composer's tricks of speech, manner of writing, and various idiosyncracies. - Summary by Preface
