Both experimental and groups completed a pre- and post-test with MBL being the independent variable. The mean difference score for the experimental group was compared to that of the control group using an independent-measures test and an analysis of variance. For the second research question, ...
Group sizes: MDL (n = 11 rats), MDM (n = 11), eYFP-Thalamus (n = 13), DMS (n = 10), VMS (n = 12), eYFP-Striatum (n = 12). Full size image DREADD-expressing animals were trained in the CombiCage 5-CSRTT23. In this modified, self-paced and ...
5b, c; experimental group: the container with AMTC), we should obtain the temperature-time curves of the goods stored in the container (Supplementary Note 13, Supplementary Fig. 23). We prepared nine volumes of water, all of equal measure but of varying initial temperatures, to simulate the...
Many lower-limb exoskeletons have been developed to assist gait, exhibiting a large range of control methods. The goal of this paper is to review and classify these control strategies, that determine how these devices interact with the user. In addition
On day 31, damage rates were significantly lower in group A as compared with other groups, which shared no significant difference among them (Fig. 2). Figure 2 The damage rate on the flowering cabbage plants (group A–D) under control environment. The Y-axis represents the plant damage ...
We study a group of hosts A and symbionts B, where members of each can invest in cooperation that bring about benefits for their partner. While microbiomes often contain many microbial species, the model follows a focal species—or equivalently the members of one niche—and asks whether microbi...
