Shanghai has experienced a rapid process of urbanization and urban expansion, which increases travel costs limits job accessibility for the economically disadvantaged population. This paper investigates jobs-housing imbalance problem in at subdistrict-level (census-level) reaches following conclusions. First, shows ring pattern is evident mainly suburban areas periphery metropolitan area becaus...

The interaction of space and time affects perception of extents: (1) the longer the exposure duration, the longer the line length is perceived and vice versa; (2) the shorter the line length is, the shorter the exposure duration is perceived. Previous studies have shown that space-time interactions in human vision are asymmetrical; spatial cognition has a larger effect on temporal cognition rat...

This work studies the temporal imbalance that processes experience when operating on a modern multicore cluster, and develops hierarchical algorithms that tolerate this imbalance. A micro-benchmark is used to investigate the nature of process imbalance with perfectly balanced workloads, and understand the nature of interversus intra-node imbalance. These insights are then used to develop imbala...

The subcarrier signal to interference-plus-noise ratio expression for orthogonal frequency division multiplexing systems impaired by in-phase/quadrature (I/Q) imbalance is a ratio of correlated random variables. In its original form, a quadruple integral is required to evaluate the exact average subcarrier SINR which is cumbersome to compute numerically. We show that the quadruple integral can ...

The spatiotemporal analysis and mapping of soil organic matter (SOM) play a pivotal role for evaluating health implementing preservation restoration actions. In this context, the first aim study is to furnish high-resolution current SOM content in eastern Croatia. second perform diachronic content, comparing two datasets characterized by an extreme data imbalance. more recent dataset (SOM2010),...

the square map is one of the functions used in cryptography. for instance, the square map is used in rabin encryption scheme, block cipher rc6 and stream cipher rabbit, in different forms. in this paper, we study statistical properties of the output of the square map as a vectorial boolean function. we obtain the joint probability distribution of arbitrary number of the upper and the lower bits...

We investigate the effect of thermal imbalance on structural stability magnetohydrodynamic model preflare current layer (Ledentsov, Sol. Phys. 296, 74, 2021). The piecewise homogeneous is supplemented by a magnetic field longitudinal with respect to direction current. It shown that presence weak does not change previously calculated spatial period instability in most expected range parameters a...

The inphase/quadrature (I/Q) amplitude and phase imbalance effects are studied in coherent optical orthogonal frequency division multiplexing (CO-OFDM) systems. An analytical model for the I/Q imbalance is developed and supported by simulation results. The results indicate that the I/Q imbalance degrades the BER performance considerably. Keywords—Coherent detection, I/Q imbalance, OFDM, optical...
