Gabriela’s group aims to find out—not by testing natural light-harvesting complexes, but by building complexes themselves. The experimentalists mimic the complex’s protein using DNA. You can fold DNA into al
. The effectiveness of aclinical trialdepends on the selection of patients in a truly random but not unethical way, and the exclusion of factors which may obscure the result. It is too late once the trial has been completed to rectify the inadequacy of the design by the use of statistics....
The field (geometrical) theory of specific heat is based on the universal thermal sum, a new mathematical tool derived from the evolution equation in the Euclidean four-dimensional spacetime, with the closed time coordinate. This theory made it possible
The design and analysis of experiments (DOE) has historically been an important part of an education in statistics, and with the increasing complexity of modern production processes and the advent of large-scale online experiments, it continues to be highly relevant. In this article, we provide ...
As shown in Table 3, the sample is representative of Irish public per the most recent national census in terms of age and gender. Sampling focused on representativeness within NUTS 3 categories (i.e., Nomenclature of Territorial Units for Statistics) while also considering areas likely to be im...
Since this is a full factorial design, experimental units are independently assigned to all treatments. The 2-factor ANOVA model is commonly used to analyze data from such designs. In later lessons, I will discuss interactions and 2-factor ANOVA in more detail. Filed under Applied Statistics, ...
Studying the mechanical properties of rock–concrete combined body is crucial to ensure the safety and stability of engineering structures. In this paper, laboratory tests and numerical simulations are used to investigate the mechanical properties of the
The course book comprises 8 units, out of which 7 units were covered. The book intended to promote the university students’ skills in reading English journalistic texts. In so doing, it elaborates on different parts of a newspaper and a news article. Through this book the students are brief...
In addition, all the dimensional parameters are reported in SI units. ParameterDescriptionValue κn Normal Spring Constant 1500 E Coefficient of Restitution 0.5 γn Normal Dash-pot Constant Eq. (5) κt Tangential Spring Constant 2/7κn γt Tangential Dash-pot Constant 1/2γn μr Rolling ...
There are thus two crucial steps in this design that can be notationally and conceptually confusing: (1) identifying communities that inform which units share behavior and (2) identifying design-relevant clusters which assist in randomizing treatment. Both of these steps technically use forms of ...
