Augmented city

Racial hatred, diplomatic conflicts, financial wars, environmental destruction, Covid-19 raging. In this imperfect world that doesn\u27t run in the way we want, we may grow numb, weary, and look for alternate realities that act as a relief from these increasingly bizarre events. And due to the current pandemic, ordinary individuals forced into isolation in a strange foreign city risk losing their psychological identity as well as their connection with the society. The city becomes a metaphor of this alienation as, in some cases, it lacks a sense of belonging by already built urban structures that disenfranchise both the individual and the citizen. Could we rebuild this lost relationship between the city and its residents by empowering the individuals to control and manipulate some part of their perceptible reality? Subjective idealism claims that to be is to be perceived. Why can\u27t we believe that what we perceive is the reality that belongs to us and create a world to escape to for a moment of relief? I propose a highly customizable city viewing system in which residents can create and share their imaginary urban public space. Just like Video Game Modifications(MOD) allow players to change the appearance of different elements of a game and add more features to the game according to their preferences, With the help of Augmented (Mixed) Reality technology, this system offers people an opportunity to Modding the real world, which is so exciting that for a specific area of the city, there will be a variety of thematic sets of virtual content for users to choose from. These contents will replace, mask, or upgrade real elements through MR devices, or new elements that don\u27t exist in reality will be simply added. I’d like to call these “Reality MOD.” And of course, in addition to downloading these Reality MODs by theme, people can also replace and delete any element in a pre-defined set of Reality MODs. At this point, people will create and embrace a version of reality that is only for themself. And they also have the right to escape from the real world in some of the extend. This thesis will take Kennedy Plaza in Providence, Rhode Island, and its surrounding context as the site to explore the possibilities on how a public space could be redesigned, transformed or improved by virtual contents. This research is also a provocative experiment which questions the rising dichotomy of technologies and digital realities as tools for freedom of expression

Scaling the twin peaks : systemic risk and dual regulation

In April 2013, the UK implemented a dual-regulation approach to financial services often referred to as twin peaks. In this paper, we assess the impact of the introduction of twin peaks regulation on the systemic risk contributions of UK financial institutions. Using a matched sample of single- and dual-regulated financial institutions, we provide evidence that twin peaks regulation resulted in a relative reduction in systemic risk for dual-regulated firms

THE RELATIONSHIP BETWEEN SHOT PUT TECHNIQUE AND MECHANICAL ENERGY OUTPUT OF CHINESE FEMALE SHOT-PUTT ATHLETES

The purpose of this study was to examine the relationship between the shot-putt technique and the energy output in Chinese female shot-putt athletes. Three-dimensional photogrammetry and a video analysis system were used to study the shot-put technique from the perspective of the body’s output of mechanical energy. It was found that, during the sliding phase, the main energy output was the kinetic energy of translation. During the transitional phase, the body expends the least energy in delivery of the shot. In the beginning of the push-off phase, the maximum amount of mechanical energy and kinetic energy was used. At the end of the push-off phase the energy output decreased. Otherwise, the relationship between the energy output with the shot putt result and technique indicated that the trunk’s energy output were closely correlated with the shot putt result. Knowledge of the trunk’s movement is of great importance to the shot-put technique

When LIBOR becomes LIEBOR : reputational penalties and bank contagion

We study whether commonality of incentives and opportunity to commit fraud trigger reputational contagion from culpable firms to nonculpable firms. Relying on a sample of 30 banks involved in fixing the London Interbank Offered Rate (LIBOR) and a control sample of 30 banks, we find that banks' reputations suffered substantial damage upon the announcement of their involvement in the scandal. We also document reputational contagion spread from banks that manipulated LIBOR to banks that shared the same incentives and opportunity to commit the fraud. The reputational contagion is more pronounced for large derivatives dealers who have had the strongest incentive to commit the fraud

The ρ\rho-meson longitudinal leading-twist distribution amplitude

In the present paper, we suggest a convenient model for the vector $\rho$-meson longitudinal leading-twist distribution amplitude $\phi_{2;\rho}^\|$, whose distribution is controlled by a single parameter $B^\|_{2;\rho}$. By choosing proper chiral current in the correlator, we obtain new light-cone sum rules (LCSR) for the $B\to\rho$ TFFs $A_1$, $A_2$ and $V$, in which the $\delta^1$-order $\phi_{2;\rho}^\|$ provides dominant contributions. Then we make a detailed discussion on the $\phi_{2;\rho}^\|$ properties via those $B\to\rho$ TFFs. A proper choice of $B^\|_{2;\rho}$ can make all the TFFs agree with the lattice QCD predictions. A prediction of $|V_{\rm ub}|$ has also been presented by using the extrapolated TFFs, which indicates that a larger $B^{\|}_{2;\rho}$ leads to a larger $|V_{\rm ub}|$. To compare with the BABAR data on $|V_{\rm ub}|$, the longitudinal leading-twist DA $\phi_{2;\rho}^\|$ prefers a doubly-humped behavior.Comment: 7 pages, 3 figures.

Renormalization group improved pQCD prediction for Υ(1S)\Upsilon(1S) leptonic decay

The complete next-to-next-to-next-to-leading order short-distance and bound-state QCD corrections to $\Upsilon(1S)$ leptonic decay rate $\Gamma(\Upsilon(1S)\to \ell^+\ell^-)$ has been finished by Beneke {\it et al.} \cite{Beneke:2014qea}. Based on those improvements, we present a renormalization group (RG) improved pQCD prediction for $\Gamma(\Upsilon(1S)\to \ell^+\ell^-)$ by applying the principle of maximum conformality (PMC). The PMC is based on RG-invariance and is designed to solve the pQCD renormalization scheme and scale ambiguities. After applying the PMC, all known-type of $\beta$-terms at all orders, which are controlled by the RG-equation, are resummed to determine optimal renormalization scale for its strong running coupling at each order. We then achieve a more convergent pQCD series, a scheme- independent and more accurate pQCD prediction for $\Upsilon(1S)$ leptonic decay, i.e. $\Gamma_{\Upsilon(1S) \to e^+ e^-}|_{\rm PMC} = 1.270^{+0.137}_{-0.187}$ keV, where the uncertainty is the squared average of the mentioned pQCD errors. This RG-improved pQCD prediction agrees with the experimental measurement within errors.Comment: 11 pages, 4 figures.
