Abstract:
In the first half of the talk, I will justify the logical reasoning behind the wearable technology and what kind of health-related information can the wearable devices provide. Then I will go through the currently available commercial devices and comment on their pros and cons. In the second half of the talk, I will introduce the technologies developed in my lab and how they can approach the unmet needs in continuous health monitoring.

Abstract:

The conclusion of recent developments in novel spectroscopic techniques and optoelectronic devices are challenging to simulate with current theoretical approaches of quantum electrodynamics (QED). This challenge is attributed to the fact that the underlying dynamics involve many degrees of freedom rendering a full quantum treatment prohibitively difficult. This difficulty reveals a significant gap at the interface of chemical dynamics and QED and raises many open questions that need to be addressed to advance material science and device technology. To develop a feasible approach for these problems, we investigate mixed quantum-classical theories for the dynamics of an electronic system interacting with an electromagnetic field.

We first consider three flavors of existing mixed quantum-classical dynamics and find that certain quantum features of the photon field, such as spontaneous emission and fluorescence, cannot be captured qualitatively. Then we propose a new Ehrenfest+R method to recover spontaneous emission while also distinguishing between electromagnetic fluctuations and coherent emission. More importantly, we have shown that Ehrenfest+R dynamics can correctly describe Raman scattering, resonant energy transfer, and the fluorescence triplet. With these promising results, the proposed semiclassical approach provide a viable route for bridging the gap between chemical dynamics and QED.

Abstract:
The purpose of this paper is to explain the reasons behind a standard essential patents (SEPs) holder’s behavior: why does a (SEPs) holder, Qualcomm for instance, insist to implement bundled rebate program for its customer, Apple for instance, under the risk of violation of antitrust law? This question is originated from the story between Qualcomm, FTC and Apple. In early 2017, both FTC and Qualcomm’s customer, Apple, sued Qualcomm for violating antitrust law. Qualcomm was alleged to manipulate “web of contracts” which are implemented by so-called “no-license, no- chips” policy to achieve its anticompetitive purpose. By addressing the case law of antitrust regime related to bundled rebate and loyalty discount, we can understand the legal risk that Qualcomm might face with is enormous. However, through the game- theoretic models in this paper, we find the reasons why Qualcomm insists to implement the bundled rebate program and loyalty discount, no matter what legal risks they face with--Qualcomm might want to prepare the future fierce competition from potential competitors. In order to ease the future loss, based on the models, Qualcomm desires to implement the bundled rebate and loyalty discount program in advance. Finally, this article will conclude into the expectations for the future of the businesses, especially for Asian businesses, which wish to implement the bundled rebate and loyalty discount in the U.S.

181013 Studying Extragalactic Background Light with CIBER

Title:
Studying Extragalactic Background Light with CIBER

Keywords:
Physics, Astronomy, Observational cosmology

Abstract:
The extragalactic background light (EBL) is the integrated intensity of all of the photons emitted along the line of sight through the universe. In this talk, I will first give an brief overview of the cosmic history, and discuss the sources and the measurement methods of the EBL. Then I will introduce the CIBER experiment (The Cosmic Infrared Background ExpeRiment), a sounding rocket experiment optimized for measuring the EBL at near infrared wavelengths, and it has flown four times from 2009 to 2013.
