Functional comparison of EncB and EncC cargo proteins in iron storage within the Myxococcus xanthus encapsulin

open access: yesFEBS Letters, EarlyView.
Encapsulins are protein nanocompartments that play an important role in iron storage. In the Myxococcus xanthus encapsulin system, two cargo proteins called EncB and EncC contribute to iron mineralization. Here, we show that EncB and EncC generate iron‐containing minerals with distinct chemical compositions, suggesting that the composition of stored ...

Two Stage Estimation in Semiparametric Model

open access: yesDEStech Transactions on Materials Science and Engineering, 2017
Considering the semi-parametric surveying adjustment models. Firstly, the estimators of parameters and nonparametric are derived by using the kernel function and least square method. Secondly, discuss the approach of bandwidth choice in the semi-parametric surveying adjustment models.

Two-Stage Designs for Phase II Clinical Trials

open access: yes, 2012
[[abstract]]Two-stage designs play an important role in the study of new drugs especially toxicity is the endpoint of interest. Given $(p_0,p_1,\alpha,\beta)$, there exists a set $$S=\{(r_1,n_1,r_2,n_2)|r_1 \leq n_1,r_2 \leq n_2,n_1\in\mathds{N},(r_1,r_2,

Structures of mycobacterial 3‐methylcrotonyl‐CoA carboxylase reveal carrier‐domain translocation between catalytic sites

open access: yesFEBS Letters, EarlyView.
Mycobacterial 3‐methylcrotonyl‐CoA carboxylase uses a mobile biotin‐carrying domain to shuttle a carboxyl group between two catalytic sites, enabling carboxylation of 3‐methylcrotonyl‐CoA during leucine breakdown. Cryo‐electron microscopy captures the carrier at both sites and reveals an inward loop movement that may prevent futile rebinding to the ...

Two-stage designs robust to model uncertainty. [PDF]

open access: yes
D-optimal designs are known to depend quite critically on the particular model that is assumed. These designs tend to concentrate all the experimental runs on a small number of design points and are ideally suited for estimating the coefficients of the ...

Chiral separation of chloroalkanes with the chromatographic column onboard Martian rovers

open access: yesFEBS Letters, EarlyView.
Computer image of the Rosalind Franklin Rover of ESA's ExoMars mission. ExoMars is scheduled to land on planet Mars in Oxia Planum in 2029. This area represents an interesting spot to look for biosignatures. Investigations of ExoMars include measurement on molecular chirality. We show that chiral chloroalkanes, that have been identified on Mars, can be

Sleep Stage Estimation Comparing Own Past Heartrate or Others' Heartrate

open access: yesSICE Journal of Control, Measurement, and System Integration, 2018
To increase the accuracy of real-time sleep stage estimation when only a small number of sleep data can be obtained such as after going to bed, the information for the subject's own sleep and other's past sleep can be used.

Artificial molecular machines and motors—Design and control of nanoscale motion

open access: yesFEBS Letters, EarlyView.
Molecules are constantly moving because of thermal fluctuations, but random motion alone cannot be exploited to perform directional tasks. Artificial molecular machines use chemical, electrical, or light energy to bias this motion. Molecular shuttles, rotary motors, and supramolecular pumps illustrate how nanoscale movement can be controlled and ...
