Interrogating cellular perception and decision making with optogenetic tools.

Optogenetics promises to deepen our understanding of how cells perceive and respond to complex and dynamic signals and how this perception regulates normal and abnormal function. In this study, we present our vision for how these nascent tools may transform our view of fundamental cell biological processes

Distribution in tropical America of Turritellas of the phylum of Turritella ocoyana

Large, strongly keeled ocoyana-like Turritellas have an extensive distribution in tropical America. So far they have been found in Mexico, Colombia, and Venezuela, all on the Caribbean side, and in Peru, Ecuador, Darien, Chiriqui Province, Panama, and Lower California, on the Pacific side. In the Caribbean region these Turritellas are found in two middle Miocene zones, the lower corresponding to the Cercado formation of the Dominican Republic, and the upper corresponding to the Gurabo formation of the Dominican Republic and the Gatun formation of the Panama Canal Zone. On the Pacific side they apparently are confined to the upper zone. Though six names have already been proposed for these tropical Turritellas, they clearly fall in the ocoyana phylum and they may eventually be considered as representing a subspecies of ocoyana. This phylum appears in California as an invader. According to available evidence it reached the Pacific from the Atlantic by way of the Central American seaways. Perhaps it developed from a lower Miocene stock represented by Turritella subgrundifera of the Chipola formation of Florida

Denial of the Rohingya Genocide: Problematising Daw Aung San Suu Kyi and the Rule of Law in Postcolonial Myanmar

As the world condemns the genocide, Myanmar and Daw Aung San Suu Kyi’s government denied it and refused to accept it and argued that it sanctioned under the rule of law. This paper problematises these questions:, What is the rule of law in Myanmar? And why do they deny it? This study is qualitative in which pages of transcripts of speeches perused to find themes, settings, and meanings attributed to problematising Daw Aung San Suu Kyi and the rule of law in post-colonial Myanmar. These speeches delivered in public from 2016-2018. In analysing her speeches, the paper uses Foucauldian Discourse Analysis. On the part of Daw Aung San Suu Kyi, it found that problematising her actions and silence over the Rohingya genocide influenced her late father’s role. She continued to claim that her military father is the father of the Burmese military. She had special relations in incarceration with the army generals during her house arrest. She focused on the democratic transition which she promised in the 2015 election.  This study reveals that this rule of law has purely political narratives because the generals are not accountable. This paper subsumes ongoing legal reforms in Myanmar

Trumpet slices of the Schwarzschild-Tangherlini spacetime

We study families of time-independent maximal and 1+log foliations of the Schwarzschild-Tangherlini spacetime, the spherically-symmetric vacuum black hole solution in D spacetime dimensions, for D >= 4. We identify special members of these families for which the spatial slices display a trumpet geometry. Using a generalization of the 1+log slicing condition that is parametrized by a constant n we recover the results of Nakao, Abe, Yoshino and Shibata in the limit of maximal slicing. We also construct a numerical code that evolves the BSSN equations for D=5 in spherical symmetry using moving-puncture coordinates, and demonstrate that these simulations settle down to the trumpet solutions.Comment: 11 pages, 6 figures, submitted to PR

Coverage Properties Of Optimized Confidence Intervals For Proportions

Wardell (1997) provided a method for constructing confidence intervals on a proportion that modifies the Clopper-Pearson (1934) interval by allowing for the upper and lower binomial tail probabilities to be set in a way that minimizes the interval width. This article investigates the coverage properties of these optimized intervals. It is found that the optimized intervals fail to provide coverage at or above the nominal rate over some portions of the binomial parameter space but may be useful as an approximate method

Bias in Stabilized Sieve Sampling

The stabilized sieve sample selection method (SSM) is considered to be a probability proportional to size (PPS) sampling method with an unbiased estimator (Horgan 1997, 1998). This article demonstrates that SSM does not select items with PPS and that the point estimator is biased

A comparison of success rates of introduced passeriform birds in New Zealand, Australia and the United States

In this study, we compiled lists of successful and unsuccessful passeriform introductions to nine sites in New Zealand, Australia and the United States. We limited our analysis to introductions during the 19th century to minimize potential variation in transport modes and habitat quality changes, such as those due to increasing urbanization. We compared introduction success rates at three levels. First we included all passeriforms introduced to any of the sites in the three locations, then we compared the fates of just those species with a European origin and finally we compared success rates of just the 13 species released into all three locations. We found that the pattern of success or failure differed significantly across the three locations: Passeriforms introduced by acclimatization organizations to the United States were significantly more likely to fail than those introduced to New Zealand or Australia. Several species that succeeded in either New Zealand or Australia failed in the United States, even after the introduction of seemingly sufficient numbers
