Feedback Inhibition00:46

Feedback Inhibition

56.9K
Biochemical reactions are occurring constantly in cells, converting starting substances to different products, usually with the help of enzymes that speed the reactions. Without enzymes, it would take far too long for most reactions to occur to be useful to the cell!

Iterative Optimization of DNA Duplexes for Crystallization of SeqA-DNA Complexes

10.3K
Crystal structure of protein–DNA complexes can provide insight into protein function, mechanism, as well as, the nature of the specific interaction. Here, we report how to optimize the length, sequence and ends of duplex DNA for co-crystallization with Escherichia coli SeqA, a negative regulator of replication...

A Vibrotactile Feedback Device for Seated Balance Assessment and Training

6.8K
A sitting platform has been developed and assembled that passively destabilizes sitting posture in humans. During the user's stabilizing task, an inertial measurement unit records the device's motion, and vibrating elements deliver performance-based feedback to the seat. The portable, versatile device may be used in rehabilitation, assessment, and training...

A "Dual-Addition" Calcium Fluorescence Assay for the High-Throughput Screening of Recombinant G Protein-Coupled Receptors

2.7K
In this work, a high-throughput, intracellular calcium fluorescence assay for 384-well plates to screen small molecule libraries on recombinant G protein-coupled receptors (GPCRs) is described. The target, the kinin receptor from the cattle fever tick, Rhipicephalus microplus, is expressed in CHO-K1 cells. This assay identifies agonists and antagonists using the same cells in one "dual-addition"...

Budget Constraint I01:26

Budget Constraint I

552
Budget constraint helps to describe the combinations of products a consumer can afford to buy with their limited income.
For instance, a student receives a weekly allowance of $100. He spends this on purchasing books and snacks. A book costs $20 and a snack costs $5. The student can purchase different combinations of these two products. For example, he can buy four books and four snacks. Alternatively, he can buy three books and eight snacks. Each of these combinations costs exactly $100,...

    Summary
    This summary is machine-generated.

    This study introduces two algorithms for distributed convex optimization. One algorithm achieves optimal convergence using a center node, while the other is fully distributed but with a slightly slower convergence rate.

    Area of Science:

    • Optimization Theory
    • Distributed Systems
    • Convex Analysis

    Background:

    • Distributed convex optimization problems often involve complex constraints.
    • Existing methods may require a central coordinator or lack optimal convergence rates.

    Purpose of the Study:

    • To develop efficient algorithms for distributed convex optimization with general constraints.
    • To analyze the convergence properties of the proposed algorithms.

    Main Methods:

    • A dual subgradient algorithm with iterate-averaging feedback for a centralized network.
    • A fully distributed algorithm using consensus tracking iterates.

    Main Results:

    • The first algorithm achieves an optimal O(1/√k) convergence rate without primal recovery issues.
    • The second algorithm offers full distribution at the cost of an O(ln k/√k) convergence rate.

    Conclusions:

    • The proposed algorithms effectively address distributed convex optimization with coupled constraints.
    • The choice between algorithms depends on the network structure and convergence requirements.
