Binary operations on pattern-avoiding cycles

open access: yes
Suppose $c_n(σ)$ denotes the number of cyclic permutations in $\mathcal{S}_n$ that avoid a pattern $σ$. In this paper, we define partial groupoid structures on cyclic pattern-avoiding permutations that allow us to build larger cyclic pattern-avoiding permutations from smaller ones. We use this structure to find recursive lower bounds on $c_n(σ)$. These

Photothermal Hydrogel with Mn3O4 Nanoparticles Alleviates Intervertebral Disc Degeneration by Scavenging ROS and Regulating Extracellular Matrix Metabolism

open access: yesAdvanced Functional Materials, EarlyView.
The MPTT‐nanozyme‐hydrogel system (Mn3O4@ChS‐HA) provides a multifunctional therapeutic strategy for intervertebral disc degeneration (IVDD), effectively targeting oxidative stress and enhancing AF repair by restoring extracellular matrix (ECM) and redox homeostasis.

Investigation on geothermal binary-flashing cycle employing zeotropic mixtures as working fluids

open access: yesGeothermal Energy, 2019
The binary-flashing cycle (BFC) is supposed to be a promising technology for geothermal recovery due to the full use of geofluid. For further performance improvement, the potential of using mixtures of a hydrocarbon and a retardant in the BFC system is ...

On the full automorphism group of a Hamiltonian cycle system of odd order

open access: yes, 2015
It is shown that a necessary condition for an abstract group G to be the full automorphism group of a Hamiltonian cycle system is that G has odd order or it is either binary, or the affine linear group AGL(1; p) with p prime.

Functional Analyses of Cytokinesis Regulators in Bloodstream Stage Trypanosoma brucei Parasites Identify Functions and Regulations Specific to the Life Cycle Stage

open access: yesmSphere, 2019
The early divergent protozoan parasite Trypanosoma brucei alternates between the insect vector and the mammalian hosts during its life cycle and proliferates through binary cell fission. The cell cycle control system in T.

Binary Rankine Cycle Optimization

open access: yes, 2005
Geopressured geothermal fluids at Croatian reservoirs contain energy in three different forms such as: dissolved gases and minerals, high pressure and relatively high temperatures. Natural gas must be separated for the optimal utilization efficiency, which simultaneously maximizes the conversion process due to the wellhead temperature.

Development of Geothermal Binary Cycle Working Fluid Properties Information and Analysis of Cycles [PDF]

open access: yes, 1978
The research discussed in this report was performed at the University of Oklahoma during the period January 1, 1979 through December 31, 1979. Efforts were directed principally to the following tasks: (1) comparisons of mixture and pure fluid cascade cycles, (2) development of guidelines for working fluid selection for single boiler cycles, (3 ...
