Sampling procedures represent a critical component of plant community studies, particularly for deep-water submersed species that are not easily observed. Here, two methods of submersed macrophyte sampling are compared for their accuracy and consistency. During 2 years of study, in-water sampling produc...

Biopsies of nasal lesions were taken from patients undergoing nasal surgery by two techniques- with nasal forceps and with nasal scissors. Each sample was examined by a senior pathologist that was blinded to the sampling method. A grading system was used to rate the crush artifact in every ...
The purpose of this note is to present a new sampling technique and to demonstrate some of its properties. The new technique consists of picking two elements at random, and deterministically generating (from them) a long sequence of pairwise-independent elements. The sequence is guaranteed to int...
the cross-over in time between different stretch powers allows one to extract the many-body system’s correlation time. We demonstrate this behaviour by actively controlling the correlation time of the P1 system via polychromatic driving, building upon techniques previously utilized in broadband decoupli...
Method of sampling and collecting the microbes in soil and root-associated compartments (a) and workflow for implementation of machine learning models for predicting two rice cultivars (b). Full size image Results Cd accumulation features consistently differed between two rice cultivars with varied soil...
On the other hand, the proportional–integral (PI) controller and the proportional-resonant (PR) controller are both types of linear control techniques that can be used in current-controlled inverters [10]. The PI controller has two drawbacks that are well-known in the industry: The weakness ...
Then, consistency is meant under a double sampling scheme in which the number of persons and number of items tends to infinity (i.e., 𝑁→∞ and |𝐼0|→∞). We now present the consistency result. Proposition 1. Assume that DIF effects 𝑒𝑖 fulfill E(𝑒𝑖)=0. For DIF ...
When the industrial material flows into the pneumatic conveying system, the valve on the branch pipeline is opened for continuous sampling and testing during the contact between the industrial material and the GS-TENG surface. Fig. 8b illustrates the structure and working principle of GS-TENG, ...
