Contextualizing Michael Jordan v. Qiaodan Sports: I Don’t Believe I Can Fly, or Do Business, in China

To be a superstar in America means to live with the pressure of maintaining a certain reputation and level of popularity during one’s professional career. Fame in America often translates to fame internationally, and well-known individuals are typically incentivized to use the constantly evolving internet and media at their disposal to increase global exposure with respect to their brands. American celebrities consequently generate social and monetary capital, and while they willingly increase fan access into their personal lives, opportunistic individuals in foreign territories have on occasion successfully invaded the trademarks of these celebrities. This issue traces back to the turn of the century, when television broadcasts were the primary form of public viewership, and individuals whose brands eclipsed global celebrity in the 1990’s and early 2000’s were the center of attention. Retrospectively thinking, many squatters who built successful businesses had filed bad faith trademark registrations and created unimaginative logo imitations by appropriating the commercial value of these individuals’ identities without consent. Generally, the rights afforded to a foreign national should be identical to those afforded to a home national. Still, enforcement of the rights of a trademark owner depend on questions surrounding the famous mark doctrine and trademark local popularity. As American nationals have urged for the cancellation of bad faith trademark registrations abroad, the definition of fame, the manner in which fame might be acquired, and the means by which fame must be protected each have taken on new meaning

Collecting and Storing Wireless Power from a RF Source

This study involved transferring power wirelessly through inductive coupling. The goal was to create a receiver device capable of powering a rectifying circuit and charging a capacitor while being at least 20 mm away from the transmitter device. This device should also be capable of receiving power when separated by non-conductive mediums other than air. The study was successful at transmitting power through an RF transmitter into an RF receiver at voltage ranges of 1V — 14V and ranges of 0cm — 20cm. It was able to charge an 80 nF capacitor to 8.39 V and had a fall time of 573 ms

Probing the hot and dense nuclear matter with K∗,Kˉ∗K^*,\bar{K}^* vector mesons

We investigate probing the hot and dense nuclear matter with strange vector mesons ($K^*, \bar{K}^*$). Our analysis is based on PHSD which incorporates partonic and hadronic dof and describes the full dynamics of HICs. This allows to study the $K^*$ and $\bar{K}^*$ meson formation from the QGP and the in-medium effects related to the modification of their properties during the propagation in dense and hot matter. We employ relativistic Breit-Wigner spectral functions for the $K^*,\bar{K}^*$ mesons with self-energies obtained from a G-matrix approach to study the role of in-medium effects on the $K^*$ and $\bar{K}^*$ meson dynamics in HIC from FAIR/NICA to LHC energies. According to our analysis most of the final $K^*/\bar{K}^*$s, that can be observed experimentally, are produced during the late hadronic phase and stem dominantly from the $K (\bar{K}) + \pi \to K^*(\bar{K}^*)$ formation channel. The amount of $K^*/\bar{K}^*$s originating from the QGP channel is comparatively small even at LHC energies and such $K^*/\bar{K}^*$s can hardly be reconstructed experimentally due to the rescattering of final pions and (anti-)kaons. This mirrors the results from our previous study on the strange vector-meson production in HICs at RHIC energies. The influence of the in-medium effects on the dynamics of the $K^*/\bar{K}^*$ is rather small since they are mostly produced at low baryon densities. Additional cuts on the shape of the observed signal and the range of the invariant mass region of the $K^*/\bar{K}^*$ also affect the final spectra. We demonstrate that the $K^*/\bar{K}^*$ in-medium effects are more visible at lower beam energy, e.g. FAIR/NICA and BES RHIC energies, where the production of $K^*/\bar{K}^*$s occurs at larger baryon densities. Finally, we present the experimental procedures to extract information on the in-medium masses and widths by fitting final mass spectra at LHC energies.Comment: 24 pages, 34 figures, extended version as published in Phys.

Observation of Tool Life of Micro End Mills

Prediction of mechanical machining tool life is an integral part of commercial manufacturing. Failure of micro end mills is still not well understood, and further work needs to be done to accurately predict tool life. The objective of this study is to observe the distribution of tool life for micro end mills under aggressive machining conditions without lubri-cation for 300-um-diameter micro end mills while machining 6061-T6 aluminum alloy. The average tool life was 3 to 7 times greater for the nanocrystalline diamond (NCD) coated micro end mills as compared with the uncoated (as received) tools. For both NCD coated and uncoated micro end mills the tool life increased as the cutting speed was in-creased from 32 to 48 m/min, suggesting the presence of a built-up-edge during machining. The variance in the tool life data was approximately an order of magnitude greater than what is expected in macro-scale machining

Investigating the origin of strangeness enhancement using jet-like [eta] − [phi] angular correlations in p-Pb Collisions with ALICE

The strong nuclear force that is responsible for binding together protons and neutrons within atomic nuclei - and responsible for forming the nucleons themselves - can be explained by a quantum field theory known as Quantum Chromodynamics (QCD). At extreme temperatures and pressures, QCD predicts the formation of a new state of nuclear matter called the Quark Gluon Plasma (QGP). The behavior of QCD interactions under these extreme conditions can be studied in the laboratory by colliding together ultra-relativistic heavy-ions, where the energy density is expected to reach well above the critical transition temperature for QGP formation. Heavy-ion collisions have been studied for decades at multiple different particle accelerator facilities, including the Large Hadron Collider (LHC). At the LHC, the primary experiment focused on studying these heavy-ion collisions is known as A Large Ion Collider Experiment (ALICE). ALICE is designed to study high multiplicity heavy-ion collisions, as well as proton-proton and proton-ion collisions that can be used as baseline measurements. Among the expected signatures of QGP formation is an increase in the production of strange quarks within the medium, a phenomenon known as strangeness enhancement. Strangeness enhancement can be studied by measuring the production ratio of strange particles to non-strange particles. While first predicted, and later observed, to be present in heavy-ion collisions, more recent measurements have observed an onset of strangeness enhancement occurring in smaller systems, such as p-Pb collisions. The enhancement seen in heavy-ion collisions can be fairly well described using a statistical hadron production model, where the temperature is high enough that the strange quark is in full equilibrium with the two other light flavor quarks. However, the microscopic behavior underlying this enhancement in smaller systems is still not completely understood. Further differentiation of strange particle production is needed to pinpoint the partonic interactions, particularly in the soft-scattering sector, responsible for strangeness enhancement. In this analysis, angular correlations between a high momentum hadron and a φ(1020) meson (comprised of a strange quark-antiquark pair) are measured within p-Pb collisions with ALICE at the LHC. With the high momentum trigger hadron acting as a proxy for a high energy jet of particles, and the φ(1020) meson acting as a strangeness probe, these correlations can be used to separate out the production of φ(1020) mesons within jets (closely aligned to the direction of the trigger) from production in the non-jet underlying event (uncorrelated with the direction of the trigger). These differential yield measurements are a way to separate out hard-scattering production (more jet-like) from soft-scattering production (more medium-like). The φ(1020) correlations can be directly compared with inclusive dihadron correlations to calculate the strange to non-strange production ratio (i.e φ/h). With this technique, strangeness production within jets and the underlying events are measured as a function of multiplicity and are compared between a lower and higher momentum region. These different production regimes show a clear ordering, with φ/h production in the underlying event significantly higher than in jets for all multiplicities. The evolution of the per-trigger yields within the near-side (jet) and away-side (modified jet) as a function of multiplicity are studied separately, and differences in behavior suggest a change to the away-side production at lower momentum. This technique for measuring yield ratios is then discussed as a way to further constrain the origin of strangeness enhancement in small systems.Physic
