We study the Price of Anarchy (PoA) of the competitive cascade game following the framework proposed by Goyal and Kearns in [11]. Our main insight is that a reduction to a Linear Threshold Model in a time-expanded graph establishes the submodularity of the social utility function. From this observation, we deduce that the game is a valid utility game, which in turn implies an upper bound of 2 o...

in this work, poly (o-anisidine) (poa) was prepared by consecutive potential cycling in an acidic monomer solution at the surface of carbon paste electrode (cpe). nickel ions were dispersed into the polymer by immersing the electrode in niso4 solution. the prepared ni/poa/cpe was characterized by scanning electron microscopy, energy dispersive x-ray spectroscopy, atomic force microscopy (afm) a...

In this work, we report an innovative approach to improve the interface properties of SiC/SiO 2 metal oxide semiconductor (MOS) capacitors. High temperature (1350°C) oxidation under different ambient is followed by a combination post-oxidation annealing (POA) treatments using N , O and NO gases. TOF-SIMS analysis shows silicon nitrogen peaks near interface. The peak attributed emission carbon a...

Afferent neural transmission of temperature sensation from skin thermoreceptors to the central thermoregulatory system is important for the defense of body temperature against environmental thermal challenges. Here, we report a thermosensory pathway that triggers physiological heat-defense responses to elevated environmental temperature. Using in vivo electrophysiological and anatomical approac...

The capturing of gel electrophoresis image represents the output of a DNA computing algorithm. Before this image is being captured, DNA computing involves parallel overlap assembly (POA) and polymerase chain reaction (PCR) that is the main of this computing algorithm. However, the design of the DNA oligonucleotides to represent a problem is quite complicated and is prone to errors. In order to ...

This article proposes a novel polarization orientation angle (POA) estimation algorithm for steep terrain by applying physical scattering characteristics of natural surface. The extends the range POA from [-45°, 45°] to (-90°,90°] and achieves consistent with widely used circular (CPA) minimum cross-polarization (MXPA) over flat area, but avoids wrapping caused restriction CPA MXPA precipitous ...

Objective This presentation aims to discuss the need and share the results from an international, multi-disciplinary mission to assess public health surveillance (PHS) in Sudan and develop a plan of action (PoA) to strengthen PHS through integration. We will present the findings of the mission and the resulting PoA developed for Public Health Surveillance Strengthening (PHSS) designed to rapidl...

Scheduling jobs of decentralized decision makers that are in competition will usually lead to cost inefficiencies. This cost inefficiency is studied using the Price of Anarchy (PoA), i.e. the ratio between the worst Nash equilibrium cost and the cost attained at the centralized optimum. First, we provide a tight upperbound for the PoA that depends on the number of machines involved. Second, we ...

Contamination of estrogenic compounds disrupts endocrinological and neurological reproductive systems in animals. Neonatal exposure to 17α-ethinyl estradiol (EE) induced an abnormal estrous cycle at postnatal day (PND) 180, but not at PND90. We found that serum level of luteinizing hormone (LH) at the latter half of proestrus in EE-treated rats was lower than in the controls at PND90 when there...
