Each activity i∈ V is associated with a known nonnegative resource requirement, rik≤ Rk, which represents the constant usage of resource type k∈ R per period by activity i. The two dummy activities 0 and n + 1 have no resource usage. In practice, a resource often represents a group ...
In this paper, we give a strong negative result for the problem of pricing loss leaders. We prove that assuming the Unique Games Conjecture (UGC), there is no constant approximation algorithm for item pricing with prices below cost allowed even when each customer is interested in at most ...
ASYMMETRY A distortion of the readback signal which is shown in different intervals between the positive and negative voltage peaks. AUXILIARYMEMORY Memory other than main memory; generally a mass-storage subsystem containing disk drives and backup tape drives, controller(s) and buffer memory (also ...
If a negative current is detected during the soft-start phase or in very low load condition, the LS_OCP is detecting this and the low-side is forced OFF. This function is also called "zero-crossing detection", because the current in the coil crosses the zero passing from positive (from ...
Since higher voltage difference between the positive and negative electrode is necessary to achieve more energy, it should be noted that hard carbons with larger capacity contribution from the flat voltage profiles will be attractive for use in commercial SIBs. All in all, it can be concluded ...
However, the edge region of the Ga K-edge XANES spectrum changes drastically for measurements at higher negative bias voltages. Spectra taken at −5 V from the p-and n-type segments (dark blue and dark orange in Fig. 4a, respectively) of the GaAs nanowire clearly reveal a strong shift...
Throughout the years of changing , schools and friends, there remained one constant in my childhood — my mother. For both my brother and me, she was the cook, maid and teacher. She played these roles while some type of part-time job. Leaving a career is just one of the sacrifices ...

We use the O-notation to show an asymptotic upper bound for a non-negative function f(n) when n goes to infinity. Hence, we say f(n) belongs to the set of functions O(g(n)) if there exist positive constants c and n0 such that 0≤f(n)≤cg(n) for all n≥n0. In other ...
Also, global single-particle moves are related to the single-particle insertion probabilities, in other words to fugacities (the exponential of the negative chemical potential) that are prohibitively small. At lower (finite) densities, however, placing at each time step a randomly chosen disk at ...
