In several emerging non-volatile technologies for main memory (NVRAM) the cost of reading is significantly cheaper than the cost of writing. Such asymmetry in memory costs leads to a desire for “writeefficient” algorithms that minimize the number of writes to the NVRAM. While several prior works have explored write-efficient algorithms for databases or for the unique properties of NAND Flash, o...

In this study, taking the Sheng’an coal mine as an engineering background, failure characteristics of surrounding rock a roadway under repeated mining in close-distance seam is comprehensively illustrated through field measurements (e.g., drilling imaging), theory analysis and numerical simulation (finite difference method (FDM)). The results show that although return airway 10905 remains intac...

During asymmetric division, a cell polarizes and differentially distributes components to its opposite ends. The subsequent division differentially segregates the two component pools to the daughters, which thereby inherit different developmental directives. In Drosophila sensory organ precursor cells, the localization of Numb protein to the cell's anterior cortex is a key patterning event and ...

Recently, several authors have criticized time-symmetrized quantum theory originated by the work of Aharonov et al. (1964). The core of this criticism was the proof, which appeared in various forms, showing that counterfactual interpretation of time-symmetrized quantum theory cannot be reconciled with the standard quantum theory. I argue here that the apparent contradiction appears due to inapp...

We intend to show that transient chaos is a very appealing, but still not widely appreciated, subfield of nonlinear dynamics. Besides flashing its basic properties and giving a brief overview of the many applications, a few recent transient-chaos-related subjects are introduced in some detail. These include the dynamics of decision making, dispersion, and sedimentation of volcanic ash, doubly t...

We experimentally observe a spontaneous temporal symmetry breaking instability in a coherently driven passive optical Kerr resonator. Using a time-symmetric configuration, we report output pulses with strongly asymmetric temporal and spectral intensity profiles, with up to 71% of the energy on the same side of the pump center frequency. The instability occurs above a certain pump power threshol...

This paper proposes a theory of liquidity dynamics. Illiquidity results from asymmetric information. Observing the historical track record teaches agents how to interpret public information and helps overcome information asymmetry. There can be an illiquidity trap: too much asymmetric information leads to the breakdown of trade, which interrupts learning and perpetuates illiquidity. Liquidity f...

This is a comment on the article “An O(logn) Approximation Ratio for the Asymmetric Traveling Salesman Path Problem” by C. Chekuri and M. Pál, Theory of Computing 3 (2007), 197–209. We observe that the LP relaxation for the Asymmetric Traveling Salesman Path Problem suggested in Section 5 of that paper is not accurate, and state a corrected linear relaxation for the problem. The inaccuracy occu...

This research attempts to explore the impacts of different types of justice and their interactions on the satisfaction toward service failure recovery. We attempt to classify justices into hygiene, motivator, or asymmetric variable, based on the concept of asymmetric effect and two factors theory proposed by Herzberg. Specifically, we predict that procedural and distributive justices are hygien...
