We evaluate Intel’s RAPL power control system, which allows users to set a power limit and then tunes processor behavior to respect that limit. We evaluate RAPL by setting power limits and running a number of standard benchmarks. We quantify RAPL along five metrics: stability, accuracy, settling time, overshoot, and efficiency. The first four are standard measures for evaluating control systems...

Background: Milk is regarded as a unique source of food for all ages. When milk is exposed to various contaminants, including lead and cadmium, it is considered a risk to humans. The presence of some metal pollutants, especially Cd and Pb, facilitates their entry into the food chain and thus increases the possibility of their toxic effects on humans and animals. Therefore, we decided to check...

We present new Big Bang Nucleosynthesis (BBN) limits on the cosmic expansion rate or relativistic energy density, quantified via number $N_\nu$ of equivalent neutrino species. use latest light element observations, neutron mean lifetime, and update our evaluation for nuclear rates $d+d \rightarrow He3 + n$ H3 p$. Combining this result with independent constraints from microwave background (CMB)...

Searches for standard model Higgs boson production in p¯ p collisions at √ s = 1.96 TeV have been carried out for Higgs boson masses (mH) in the range 105 < mH < 200 GeV/c 2. Analyses are conducted with integrated luminosities from 1.0 fb −1 to 2.3 fb −1. As no significant excess is observed, we proceed to set limits on standard model Higgs boson production. The observed 95% confidence level up...

Searches for standard model Higgs boson production in p¯ p collisions at √ s = 1.96 TeV have been carried out for Higgs boson masses (mH) in the range 100 < mH < 200 GeV/c 2. Analyses are conducted with integrated luminosities from 1.1 fb −1 to 3.0 fb −1. As no significant excess is observed, we proceed to set limits on standard model Higgs boson production. The observed 95% confidence level up...

Searches for standard model Higgs boson production in p¯ p collisions at √ s = 1.96 TeV have been carried out for Higgs boson masses (mH) in the range 100 < mH < 200 GeV/c 2. The contributing production processes include associated production (q ¯ q →W/ZH), gluon fusion (gg →H), and vector boson fusion (q ¯ q →q ¯ q H). Analyses are conducted with integrated luminosities from 0.9 fb −1 to 5.0 f...
