ChatGPT Unveiled: Unleashing AI Magic in Online Shopping and Digital Marketing
This research paper explores the use of AI, specifically ChatGPT, in interactive activities within
online shopping and digital marketing. The paper examines the potential of AI-powered chatbots
to enhance customer engagement, personalization, and marketing effectiveness. Through a
literature review, case studies, and user feedback analysis, the research highlights the benefits of
AI chatbots in providing real-time assistance, personalized recommendations, and improved
customer experiences. The paper also addresses ethical and privacy concerns associated with AI
implementation and discusses future research directions. The findings are expected to suggest
that AI-powered chatbots have the potential to revolutionize online shopping and digital
marketing by offering enhanced customer engagement, optimizing marketing strategies, and
addressing customer needs. E-commerce preferences of human-mediated services to technologymediated
ones regarding the application of AI in frontline services will be examined
Dust-wind interactions can intensify aerosol pollution over eastern China.
Eastern China has experienced severe and persistent winter haze episodes in recent years due to intensification of aerosol pollution. In addition to anthropogenic emissions, the winter aerosol pollution over eastern China is associated with unusual meteorological conditions, including weaker wind speeds. Here we show, based on model simulations, that during years with decreased wind speed, large decreases in dust emissions (29%) moderate the wintertime land-sea surface air temperature difference and further decrease winds by -0.06 (±0.05) m s-1 averaged over eastern China. The dust-induced lower winds enhance stagnation of air and account for about 13% of increasing aerosol concentrations over eastern China. Although recent increases in anthropogenic emissions are the main factor causing haze over eastern China, we conclude that natural emissions also exert a significant influence on the increases in wintertime aerosol concentrations, with important implications that need to be taken into account by air quality studies
Exact field ionization rates in the barrier suppression-regime from numerical TDSE calculations
Numerically determined ionization rates for the field ionization of atomic
hydrogen in strong and short laser pulses are presented. The laser pulse
intensity reaches the so-called "barrier suppression ionization" regime where
field ionization occurs within a few half laser cycles. Comparison of our
numerical results with analytical theories frequently used shows poor
agreement. An empirical formula for the "barrier suppression ionization"-rate
is presented. This rate reproduces very well the course of the numerically
determined ground state populations for laser pulses with different length,
shape, amplitude, and frequency.

Multifunctional photonic integrated circuit for diverse microwave signal generation, transmission and processing
Microwave photonics (MWP) studies the interaction between microwave and
optical waves for the generation, transmission and processing of microwave
signals (i.e., three key domains), taking advantages of broad bandwidth and low
loss offered by modern photonics. Integrated MWP using photonic integrated
circuits (PICs) can reach a compact, reliable and green implementation. Most
PICs, however, are recently developed to perform one or more functions
restricted inside a single domain. In this paper, as highly desired, a
multifunctional PIC is proposed to cover the three key domains. The PIC is
fabricated on InP platform by monolithically integrating four laser diodes and
two modulators. Using the multifunctional PIC, seven fundamental functions
across microwave signal generation, transmission and processing are
demonstrated experimentally. Outdoor field trials for electromagnetic
environment surveillance along an in-service high-speed railway are also
performed. The success to such a PIC marks a key step forward for practical and
massive MWP implementations.Comment: 17 page
An integral gated mode single photon detector at telecom wavelengths
We demonstrate an integral gated mode single photon detector at telecom
wavelengths. The charge number of an avalanche pulse rather than the peak
current is monitored for single-photon detection. The transient spikes in
conventional gated mode operation are canceled completely by integrating, which
enables one to improve the performance of single photon detector greatly with
the same avalanche photodiode. This method has achieved a detection efficiency
of 29.9% at the dark count probability per gate equal to 5.57E-6/gate
(1.11E-6/ns) at 1550nm.Comment: word to PDF, 3 pages with 4 figure
Smart Avatars in JackMOO
Creation of compelling 3-dimensional, multi-user virtual worlds for education and training applications requires a high degree of realism in the appearance, interaction, and behavior of avatars within the scene. Our goal is to develop and/or adapt existing 3-dimensional technologies to provide training scenarios across the Internet in a form as close as possible to the appearance and interaction expected of live situations with human participants. We have produced a prototype system, JackMOO, which combines Jack, a virtual human system, and LambdaMOO, a multiuser, network-accessible, programmable, interactive server. Jack provides the visual realization of avatars and other objects. LambdaMOO provides the web-accessible communication, programability, and persistent object database. The combined JackMOO allows us to store the richer semantic information necessitated by the scope and range of human actions that an avatar must portray, and to express those actions in the form of imperative sentences. This paper describes JackMOO, its components, and a prototype application with five virtual human agents
WHEN PRIVACY PROCLIVITY MEET COVID-19: NO LONGER CONCERNS OF TODAY’S M-COMMERCE USERS?
This is continuous research of our previous publication (Thomas et al., 2021). A new two by two study (Before and After COVID 19) X (China and the US culture) was designed to test the moderated mediation effect of the COVID pandemic on M-commerce user’s privacy proclivity, trust, and M-commerce intention! A new sample was collected from two countries in different time periods (Before and after COVID pandemic) to investigate whether M-commerce users’ concern about privacy proclivity has changed after COVID-19. Built on top of our 2021 publication, this study discovered that privacy proclivity no longer has a significant direct impact on consumers’ M-commerce intentions after COVID, as consumers’ desires for convenience outweigh their privacy risk concerns. However, privacy proclivity still has significant influence on consumers’ M-commerce Trust, therefore, it has an indirect impact on M-commerce intentions, but the impact is limited. Finally, the results from Hayes’ PROCESS replicated our previous study findings that culture plays a moderating role in the relationship between privacy proclivity and m-commerce trust after COVID-19 outbreak (Thomas et al., 2021). The impact of privacy proclivity is stronger on M-commerce Trust in China than in the US
