Anomalous free energy changes induced by topology.

چکیده
We report that nontrivial topology of a driven Brownian particle restricted on a ring leads to anomalous behaviors on free energy change. Starting from steady states with identical distribution and current on the ring, free energy changes are distinct and nonperiodic after the system is driven by the same periodic force protocol. We demonstrate our observation in examples through both exact solutions and numerical simulations. The free energy calculated here can be measured in recent experimental systems.

TopologyNet: Topology based deep convolutional and multi-task neural networks for biomolecular property predictions
Although deep learning approaches have had tremendous success in image, video and audio processing, computer vision, and speech recognition, their applications to three-dimensional (3D) biomolecular structural data sets have been hindered by the geometric and biological complexity. To address this problem we introduce the element-specific persistent homology (ESPH) method. ESPH represents 3D co...

Single phase polycrystalline Gd1-xPrxBa2Cu3O7-δ samples with x=0.05 , 0.10, and 0.15 have been prepared by standard solid state reaction technique and characterized by XRD and SEM analysis. The electrical resistivity, Hall effect and magnetoresistance measurements have been on the samples. The electrical resistivity measurements indicate a reduction of transition temperature (Tc) and an incre...
متن کاملPhase transitions and configuration space topology
Equilibrium phase transitions may be defined as nonanalytic points of thermodynamic functions, e. g., of the canonical free energy. Given a certain physical system, it is of interest to understand which properties of the system account for the presence, respectively the absence, of a phase transition, and an understanding of these properties may lead to a deeper understanding of the physical ph...
متن کاملMolecular Dynamics Simulation and Free Energy Studies on the Interaction of Salicylic Acid with Human Serum Albumin (HSA)
Human serum albumin (HSA) is the most abundant protein in the blood plasma. Molecular dynamics simulations of subdomain IIA of HSA and its complex with salicylic acid (SAL) were performed to investigate structural changes induced by the ligand binding. To estimate the binding affinity of SAL molecule to subdomains IB and IIA in HSA protein, binding free energies were calculated using the Molecu...
متن کاملTopology Control in Wireless Sensor Network using Fuzzy Logic
Network sensors consist of sensor nodes in which every node covers a limited area. The most common use ofthese networks is in unreachable fields.Sink is a node that collects data from other nodes.One of the main challenges in these networks is the limitation of nodes battery (power supply). Therefore, the use oftopology control is required to decrease power consumption and increase network acce...
