Hypothesis testing and power calculations for taxonomic-based human microbiome data. [PDF]
This paper presents new biostatistical methods for the analysis of microbiome data based on a fully parametric approach using all the data. The Dirichlet-multinomial distribution allows the analyst to calculate power and sample sizes for experimental ...

Resonance Transitions in the Spectra of the Ag6+–Ag8+ Ions
The spectrum of silver, excited in a vacuum spark, was recorded in the region 150–350 Å on a 3-m grazing incidence spectrograph. The resonance 4dk–(4dk−15p + 4dk−14f + 4p54dk+1) was studied in the Ag6+–Ag8+ spectra (Ag VII–Ag IX) with k = 5–3 ...

A parametric sonar performance calculator [PDF]
Predicting the difference frequency source levels and beamwidths which will be developed by a given parametric sonar projector is a somewhat complicated procedure involving a number of calculations and the use of several curves or nomograms. We will introduce a slide calculator we have developed which will compute in a relatively straightforward manner

Spectrum and Energy Levels of Four-Times Ionized Yttrium (Y V)
The analysis of the spectrum of four-times-ionized yttrium, Y V, was extended to provide a large number of new spectrum lines and energy levels. The new analysis is based on spectrograms made with sliding-spark discharges on 10.7 m normal- and grazing ...

Reduction of Feynman integrals in the parametric representation
In this paper, the reduction of Feynman integrals in the parametric representation is considered. This method proves to be more efficient than the integration-by-part (IBP) method in the momentum space.

Spectrum of Sn5+ in the Region 500–1300 Å
The spectrum of tin, excited in a vacuum spark, was recorded in the region 500–1131 Å on a 6.65-m normal incidence spectrograph. The transitions between 4d85s, 4d86s, 4d85p and 4d85d excited configurations in Sn VI were studied.

Analysis and design of cold-formed steel modular building frame with SCIA Engineer [PDF]
The Industrialised Building System (IBS) is a well-known construction method with many advantages for future construction. However, IBS adoption in Malaysia remains low, particularly when coldformed steel (CFS) is used. A study on structural analysis and
