description: We present constraints on the abundance of carbon-monoxide in the early Universe from the CO Power Spectrum Survey (COPSS). We utilize a data set collected between 2005 and 2008 using the Sunyaev-Zel'dovich Array (SZA), which were previously used to measure arcminute-scale fluctuations of the CMB. This data set features observations of 44 fields, covering an effective area of 1.7 square degrees, over a frequency range of 27 to 35 GHz. Using the technique of intensity mapping, we are able to probe the CO(1-0) transition, with sensitivity to spatial modes between $k=0.5{-}2\ h\,\textrm{Mpc}^{-1}$ over a range in redshift of $z=2.3{-}3.3$, spanning a comoving volume of $3.6\times10^{6}\ h^{-3}\,\textrm{Mpc}^{3}$. We demonstrate our ability to mitigate foregrounds, and present estimates of the impact of continuum sources on our measurement. We constrain the CO power spectrum to $P_{\textrm{CO}}<2.6\times10^{4}\ μ\textrm{K}^{2} (h^{-1}\,\textrm{Mpc})^{3}$, or $Δ^{2}_{\textrm{CO}}(k\! = \! 1 \ h\,\textrm{Mpc}^{-1})<1.3 \times10^{3}\ μ\textrm{K}^{2}$, at $95\%$ confidence. This limit resides near optimistic predictions for the CO power spectrum. Under the assumption that CO emission is proportional to halo mass during bursts of active star formation, this corresponds to a limit on the ratio of $\textrm{CO}(1{-}0)$ luminosity to host halo mass of $A_{\textrm{CO}}<1.2\times10^{-5}\ L_{\odot}\ M_{\odot}^{-1}$. Further assuming a Milky Way-like conversion factor between CO luminosity and molecular gas mass ($α_{\textrm{CO}}=4.3\ M_{\odot}\ (\textrm{K}\ \textrm{km}\ \textrm{s}^{-1}\ \textrm{pc}^{-2})^{-1}$), we constrain the global density of molecular gas to $ρ_{z\sim3}(M_{\textrm{H}_{2}})\leq 2.8 \times10^{8}\ M_{\odot}\ \textrm{Mpc}^{-3}$.

Association between Patient-Reported and Performance-Based Measurements of Physical Function in an Arthritis Sample
Creators: name: Durbha, Sravya
Publisher: name: The University of North Carolina at Chapel Hill University Libraries
Year: 2014

description: Patient-reported data, specifically patient-reported outcomes (PRO) measurement, has
grown in relevance to patient-centeredness in healthcare delivery as well as in clinical
outcomes research. Nonetheless, the uptake of PRO measurement tools, although
many have been validated and approved for use in research settings, has been slow on
the part of clinical outcomes researchers due to their preference for more objective,
performance-based outcomes measurement. Consequently, there is a need for
confirming the value of PROs in patient-centered research and assessing the role
dynamic of PROs versus performance-based tests in outcomes research. In an effort to
fill investigators’ knowledge gap in this area, the following secondary data analysis,
conducted upon baseline and follow-up data from the 2011 Walk With Ease program (a
community walking program for arthritis patients), evaluated the validity and value of
PRO measures as compared to performance-based measures of physical functioning.
Primary results found that patient-reported and performance-based measures were
poorly correlated with one another, indicating that they measure physical function
differently from one another. Furthermore, both measures detected significant changes
in physical functioning over time, indicating that they may be equivalently effective in
assessing an intervention centered on improving physical functioning. Finally, the
patient-reported measures were more strongly inversely correlated with other key
arthritis symptoms than performance-based measures, meaning they may have been
more effective in measuring physical function in the context of arthritis. There findings
will ideally provide an impetus for researchers to recognize the validity and value-added
of patient-reported data and incorporate it more widely into outcomes research.

description: We explore theoretically the physics of dynamic hysteresis for driven-dissipative nonlinear photonic resonators. In the regime where the semiclassical mean-field theory predicts bistability, the exact steady-state density matrix is known to be unique, being a statistical mixture of two states: in particular, no static hysteresis cycle of the excited population occurs as a function of the driving intensity. Here, we predict that in the quantum regime a dynamic hysteresis with a rich phenomenology does appear when sweeping the driving amplitude in a finite time. The hysteresis area as a function of the sweep time reveals a double power-law decay, with a behavior qualitatively different from the mean-field predictions. The dynamic hysteresis power-law in the slow sweep limit defines a characteristic time, which depends dramatically on the size of the nonlinearity and on the frequency detuning between the driving and the resonator. In the strong nonlinearity regime, the characteristic time oscillates as a function of the intrinsic system parameters due to multiphotonic resonances. We show that the dynamic hysteresis for the considered class of driven-dissipative systems is due to a non-adiabatic response region with connections to the Kibble-Zurek mechanism for quenched phase transitions. We also consider the case of two coupled driven-dissipative nonlinear resonators, showing that dynamic hysteresis and power-law behavior occur also in presence of correlations between resonators. Our theoretical predictions can be explored in a broad variety of physical systems, e.g., circuit QED superconducting resonators and semiconductor optical microcavities.

Towards Composable Prediction of Contact Groups

Year: 2015

description: This research project focuses on the creation and testing of pre-generated groups of
contacts that contain e-mail addresses that the user is likely to send e-mail to as a group in the
future. The purpose of these generated groups is to make it as easy as possible for the user to
send a message to a group of people without modifying the group as much as possible. Some
groups may be very large and thus will make sending e-mail more efficient as they will save the
user from a lot of typing. These groups are automatically generated and recommended to the
user, who will accept the group as it is, modify it then accept it, or reject it if it does not mean
anything to the user. After coming up with several different algorithms to generate the groups,
we tested them by running a user study and collecting data from 19 participants. We then
calculated the average percentage difference between a predicted group and a future message.
This allows us to see how viable our groups are and how likely they are to help a user compose
an e-mail message in the future. We concluded that using Google score was the best method.

The mass fraction of AGN and the Fundamental Plane of black hole activity from a large X-ray selected sample of LINERs

description: A sample of 576 X-ray selected LINERs was constructed by combining data from the 3XMM-DR4 and SDSS-DR7 catalogues. The sample was used to investigate the fraction of galaxies hosting a LINER, finding that the fraction is a strong function of both stellar mass and black hole mass (scaling to the power of 1.6 +/- 0.2 and 0.6 +/- 0.1 respectively) and that it rises close to unity at the highest black hole masses and lowest X-ray luminosities. After obtaining radio flux densities from the FIRST survey, the sample was also used to investigate the Fundamental Plane of black hole activity - a scale-invariant relationship between black hole mass, X-ray luminosity and radio luminosity that is believed to hold across at least nine orders of magnitude of mass. There are key advantages in using only LINERs for the derivation as these are the counterparts of the "low-hard" X-ray binaries for which the relationship is tightest. The Fundamental Plane was found to be log (L_R / erg/s) = (0.65 +/- 0.07) log (L_X / 10^42 erg/s) + (0.69 +/- 0.10) log (M_BH / 10^8 M_solar) + (38.35 +/- 0.10). The scatter around the plane was 0.73 +/- 0.03 dex, too large to suggest that the Fundamental Plane can be used as a tool to estimate black hole mass from the observables of X-ray and radio luminosity. The black hole mass scaling is sensitive to the slope of the mass - velocity dispersion relation and, in order to achieve consistency with X-ray binaries, the analysis favours a steep gradient for this relationship, as found in recent research.

description: The (super) Schottky uniformization of compact (super) Riemann surfaces is briefly reviewed. Deformations of super Riemann surface by gravitinos and Beltrami parameters are recast in terms of super Schottky group cohomology. It is checked that the super Schottky group formula for the period matrix of a non-split surface matches its expression in terms of a gravitino and Beltrami parameter on a split surface. The relationship between (super) Schottky groups and the construction of surfaces by gluing pairs of punctures is discussed in an appendix.

Effect of Exercise Intensity on Appetite Regulation: Influence of Sex and Body Composition
Creators: name: Ahuja, Shawn
Publisher: name: The University of North Carolina at Chapel Hill University Libraries
Year: 2019

description: Background: Prior literature has shown an acute appetite suppression effect following exercise. The effect different exercise intensities and modalities has on appetite suppression remains to be seen. Furthermore, investigating the role sex and body composition plays may better tailor exercise recommendations for weight loss. Purpose: To evaluate the acute effects of HIIT and HIRT, in comparison to MICT on appetite and to explore the regulatory effect of sex and level of body fat on appetite response from an acute bout of HIIT or HIRT in comparison to MICT. Methods: Fourteen subjects (7 men, 7 women; age: 22.8±4.5, weight: 75±14.6 kg, %BF: 24.6±6.6%) volunteered for this study. Body composition was measured using dual energy x-ray absorptiometry. Appetite was assessed by visual analog scale (VAS), the Leeds Food Preferences Questionnaire (LFPQ), and plasma acetylated ghrelin (AG). Following a maximal strength test, participants completed a bout of HIIT, HIRT, and MICT in randomized crossover fashion with a one-week minimum washout period between each bout. VAS and LFPQ were taken before (Pre), immediately after (IP), 30 minutes after (30P), and 60 minutes (60P) after each bout. AG was taken Pre and 30P. Results: Subjective appetite was significantly lower in HIIT compared to MICT (p=0.017), while AG was significantly lower in HIRT compared to MICT (p=0.004). HIIT and MICT led to a significantly greater food preference of calorically dense foods following exercise while HIRT led to a lower preference (p=0.049; p=0.039; p=0.027). FM was correlated with fullness after HIIT (R=0.596; p=0.017), and LM was inversely correlated with micronutrient dense foods following MICT (R=-0.544; p=0.044). Men had greater preferences for calorically dense foods following exercise than women (p=0.001). Discussion: HIIT had a greater immediate suppression in appetite compared to MICT but did not have a significant decrease in ghrelin like HIRT. The cause for this may be rooted in an increase in intensity related byproducts and hormones such as lactate, adrenaline, and cortisol. HIIT appears to confer a greater preference for calorically dense foods while HIRT confers a lower preference for calorically dense foods after the exercise bout. MICT appears to confer a greater preference for calorically dense foods after exercise. Overweight and obese individuals may confer greater appetite suppression from HIIT while lean individuals may wish to avoid MICT to improve preference for micronutrient dense foods. There were greater food preferences in men and no subjective appetite differences contrary to prior literature.

description: Android devices continue to grow in popularity and capability meaning the need for a forensically sound evidence collection methodology for these devices also increases. This chapter proposes a methodology for evidence collection and analysis for Android devices that is, as far as practical, device agnostic. Android devices may contain a significant amount of evidential data that could be essential to a forensic practitioner in their investigations. However, the retrieval of this data requires that the practitioner understand and utilize techniques to analyze information collected from the device. The major contribution of this research is an in-depth evidence collection and analysis methodology for forensic practitioners.

Demonstration of Open Quantum System Optimal Control in Dynamic Nuclear Polarization

Year: 2015
Subjects: subject: Quantum Physics (quant-ph)

description: Dynamic nuclear polarization (DNP) is used in nuclear magnetic resonance (NMR) to transfer polarization from electron spins to nuclear spins. The resulting nuclear polarization enhancement can, in theory, be two or three orders of magnitude depending on the sample. In solid state systems, however, there are competing mechanisms of DNP, which, when occurring simultaneously, reduce the net polarization enhancement of the nuclear spin. We present a simple quantum description of DNP and apply optimal control theory (OCT) with an open quantum system framework to design pulses that select one DNP process and suppress the others. We demonstrate experimentally an order of magnitude improvement in the DNP enhancement using OCT pulses.

description: To solve a number of problems in solar physics related to mechanisms of energy release in solar corona parameters of hot coronal plasma are required, such as energy distribution, emission measure, differential emission measure, and their evolution with time. Of special interest is the distribution of solar plasma by energies, which can evolve from a nearly Maxwellian distribution to a distribution with a more complex structure during a solar flare. The exact form of this distribution for low-energy particles, which receive the bulk of flare energy, is still poorly known; therefore, detailed investigations are required. We present a developed method of simultaneous fitting of data from two spacecrafts Solar Dynamics Observatory/Atmospheric Imaging Assembly (SDO/AIA) and Reuven Ramaty High Energy Solar Spectroscopic Imager (RHESSI), using a differential emission measure and a thin target model for the August 14, 2010 flare event.
Commensal Gut Bacteria Regulate Paneth Cell Function Putatively Via Signaling Through the Sub-Epithelial Tissue

description: Crohn’s Disease (CD) is an inflammatory disorder of the intestines caused by a
dysregulated immune response to resident gut bacteria. Presently, most treatments for CD
suppress the host immune system, which can lead to adverse side effects such as
increased susceptibility to infections and malignancy. Hence, low-risk alternative
treatment options are needed. Studies suggest that defects in Paneth cells (PCs) contribute to CD pathogenesis. PCs are specialized intestinal epithelial cells that regulate the gut microbiota through the secretion of antimicrobial peptides (AMPs). However, the reciprocal impact of the gut microbiota, as well as the role of the underlying intestinal stroma on PC function is still unclear.

description: This paper considers the problem of tracking a dynamic sparse channel in a broadband wireless communication system. A probabilistic signal model is firstly proposed to describe the special features of temporal correlations of dynamic sparse channels: path delays change slowly over time, while path gains evolve faster. Based on such temporal correlations, we then propose the differential orthogonal matching pursuit (D-OMP) algorithm to track a dynamic sparse channel in a sequential way by updating the small channel variation over time. Compared with other channel tracking algorithms, simulation results demonstrate that the proposed D-OMP algorithm can track dynamic sparse channels faster with improved accuracy.

Numerical and Physical Modeling of Fluid through Rigid Structures

Publisher: name: The University of North Carolina at Chapel Hill University Libraries
Year: 2019

description: The movement of very small aquatic organisms depends heavily on the fluid around them, as they are easily influenced by the dynamics of their system. Therefore, current research seeks to understand the complex fluid dynamics of these small-scale systems to better understand how these dynamics can affect their locomotion. Numerical models of these environments are challenging to create due to the level of detail required and the massive number of computations that must be solved, but new improvements in scientific computing have recently made these models more feasible. In this paper, we largely seek to study rooted aquatic vegetation consisting of macrophytes, and their effects on the fluid dynamics of their system and the distribution of zooplankton within it. To successfully research the movement of organisms and particles in these aquatic ecosystems, it is necessary to understand how variations in macrophytes affect the fluid dynamics around them and be able to successfully model these dynamics. In this project, fluid flow through rigid physical models of aquatic vegetation is analyzed to quantify the flow profiles caused by varying the height and density of macrophyte configurations.  The dynamics are modeled in several different ways to evaluate the computational cost and accuracy of each model, with the intention of supporting a later project assessing flexible macrophytes and their impact on the distribution of zooplankton.

description: Serotonin is an important mediator modulating behavior, metabolism, sleep, control of breathing, and upper airway function, but the role of aging in serotonin-mediated effects has not been previously defined. Our study aimed to examine the effect of brain serotonin deficiency on breathing during sleep and metabolism in younger and older mice. We measured breathing during sleep, hypercapnic ventilatory response (HCVR), CO2 production (VCO2), and O2 consumption (VO2) in 16–18- week old and 40–44-week old mice with deficiency of tryptophan hydroxylase 2 (Tph2), which regulates serotonin synthesis specifically in neurons, compared to Tph2+/+ mice. As expected, aging decreased VCO2 and VO2. Tph2 knockout resulted in an increase in both metabolic indexes and no interaction between age and the genotype was observed. During wakefulness, neither age nor genotype had an effect on minute ventilation. The genotype did not affect hypercapnic sensitivity in younger mice. During sleep, Tph2−/− mice showed significant decreases in maximal inspiratory flow in NREM sleep, respiratory rate, and oxyhemoglobin saturation in REM sleep, compared to wildtype, regardless of age. Neither serotonin deficiency nor aging affected the frequency of flow limited breaths (a marker of upper airway closure) or apneas. Serotonin deficiency increased the amount and efficiency of sleep only in older animals. In conclusion, younger Tph2−/− mice were able to defend their ventilation and phenotypically did not differ from wildtype during wakefulness. In contrast, both young and old Tph2−/− mice showed sleep-related hypoventilation, which was manifested by hypoxemia during REM sleep.

description: Climate change has been well-established in the academic community, and has been studied for centuries. It is predicted to have many effects on the world, one of them being increases in water stress. Water stress can be seen through shifting precipitation patterns in both directions, shifting access to groundwater or changing groundwater supply, and increased demand, among other factors. This study looks at how precipitation changes have had an impact on conflict severity in countries throughout Africa, as well as how ethnic group distributions, temperature changes, GDP levels, and regional changes affect conflict severity through negative binomial regressions. It looks at conflicts from 1997 to 2014 on the African continent. When conflicts occur during times of negative water stress, the results indicated an increase in conflict severity and supported the hypotheses. When conflicts occur during times of positive water stress, the results differed depending on the region. As water stress worsens and temperatures increase with global warming, conflicts will get more severe, especially for less developed nations with large numbers of ethnic groups.

description: We analyze the spectrum of harmonic flow, $v_n(p_T)$ for $n=0\text{--}5$, in event-by-event hydrodynamic simulations of Pb+Pb collisions at the CERN Large Hadron Collider ($\sqrt{s_{NN}}=2.76\,{\text{TeV}}$) with principal component analysis (PCA). The PCA procedure finds two dominant contributions to the two-particle correlation function. The leading component is identified with the event plane $v_n(p_T)$, while the subleading component is responsible for factorization breaking in hydrodynamics. For $v_0$, $v_1$, and $v_3$ the subleading flow is a response to the radial excitation of the corresponding eccentricity. By contrast, for $v_2$ the subleading flow in \emph{peripheral collisions} is dominated by the nonlinear mixing between the leading elliptic flow and radial flow fluctuations. In the $v_2$ case, the sub-sub-leading mode more closely reflects the response to the radial excitation of $\varepsilon_2$. A consequence of this picture is that the elliptic flow fluctuations and factorization breaking change rapidly with centrality, and in central collisions (where the leading $v_2$ is small and nonlinear effects can be neglected) the subsub-leading mode becomes important. Radial flow fluctuations and nonlinear mixing also play a significant role in the factorization breaking of $v_4$ and $v_5$. We construct good geometric predictors for the orientation and magnitudes of the leading and subleading flows based on a linear response to the geometry, and a quadratic mixing between the leading principal components. Finally, we suggest a set of measurements involving three point correlations which can experimentally corroborate the nonlinear mixing of radial and elliptic flow and its important contribution to factorization breaking as a function of centrality.

description: The present research intends to analyse the European Union law with regard to “Protected Entry Procedures” for individuals who need international protection in order to entering EU territory. The focus of this study is the asylum seekers’ issues, more specifically how the EU Visa Code provides the “asylum status” based on humanitarian grounds stated on articles 25 (1) and 19 (4). Currently, the European Union is facing one of the highest mass movements of asylum seekers during the last years. The European Community has adopted measures in order to grant refugees status through a Common European Asylum System among its Member States; and, for those asylum seekers that are within the EU territory. However, the law does not safeguard those who need legal channels to reach a Member State. Therefore, this study examines the implementation of the humanitarian visa by the Member States’ practices in order to offer safe legal entry for asylum seekers, where the Member States meet their obligations under international human rights instruments.. Likewise, we attempt to analyse how the European Community is trying to stimulate the Member States to make use of the humanitarian visa. This research proposes a recast on the EU Visa Code in order to harmonise the issuing of humanitarian visas.
The Enthroned Nude Female: An Exploration of Nabataean Domestic Religion Through a Terracotta Figurine

description: INTRODUCTION
Religion in the ancient world was interwoven into the lives of its inhabitants. Temples
and public shrines were prominent in the landscapes of the greatest cities to the smallest villages,
emphasizing the divine force thought to control every aspect of life. Such monuments have
received much attention, archaeologically and historically, for their importance in the culture of
these past societies. These centers of religion, however, often addressed the broad concerns of
the state and society; for example, the purpose of Egyptian temples was to maintain ma’at and
the order of the universe. However, religious practice extended far beyond the precinct of the
temple and was often integrated into the daily lives of all classes of society, from the elite to the
common worker.
In domestic space, for example, more intimate concerns were considered, particularly
those revolving around individuals’ daily and home lives. Because of the frequent differences
between the religion of the temple, which was often state-ordained and directed, and that
practiced by individuals at the personal level, the investigation of religion beyond the temple
temenos can provide great insight. The religious activities and objects of the home often
illuminate a society’s beliefs as to how certain forces affected their daily lives with regard to
issues ranging from sickness to procreation, and how such forces could be manipulated.
Additionally, the traditions of the home, while maintaining a degree of continuity with those of
the temple through similar objects and practices, tend to be traditions that are slow to change,
allowing a look into practices and beliefs that stretch far into the past.
This thesis focuses on an object type that gives a glimpse into such beliefs and traditions
of one society, Nabataea. Terracotta figurines were a frequent part of domestic religious practice
in the ancient Near East and Mediterranean.1 Through an in-depth analysis of the Enthroned
Nude Female, an anthropomorphic terracotta figurine common to Nabataean domestic contexts,
this study will show that Nabataea was no exception to the use of such objects in domestic
religion, and that this figurine type is quite informative concerning the character of Nabataean
domestic religion. This introductory chapter begins with a brief background of the land and
people of Nabataea. Additionally, a review is conducted of the previous research into Nabataean
religion and Nabataean terracotta figurines. Lastly, the goals and structure of this research are
outlined in Section 1.4, thereby establishing the framework for the thesis.
How admitting migrants with any skills can help overcome a shortage of workers with particular skills

subject: Skill acquisition subsidy

description: A country that experiences a shortage of workers with particular skills naturally considers two responses: import skills or produce them. Skill import may result in large-scale migration, which will not be to the liking of the natives. Skill production will require financial incentives, which will not be to the liking of the ministry of finance. In this paper we suggest a third response: impose a substantial migration admission fee, “import” fee-paying workers regardless of their skills, and use the revenue from the fee to subsidize the acquisition of the required skills by the natives. We calculate the minimal fee that will remedy the shortage of workers with particular skills with fewer migrants than under the skill “import” policy.

description: Obesity can cause hypertension and exacerbates sleep-disordered breathing (SDB). Leptin is an adipocyte-produced hormone, which increases metabolic rate, suppresses appetite, modulates control of breathing, and increases blood pressure. Obese individuals with high circulating levels of leptin are resistant to metabolic and respiratory effects of leptin, but they appear to be sensitive to hypertensive effects of this hormone. Obesity-induced hypertension has been associated with hyperleptinemia. New Zealand obese (NZO) mice, a model of polygenic obesity, have high levels of circulating leptin and hypertension, and are prone to develop SDB, similarly to human obesity. We hypothesize that systemic leptin receptor blocker Allo-aca will treat hypertension in NZO mice without any effect on body weight, food intake, or breathing. Male NZO mice, 12–13 weeks of age, were treated with Allo-aca (n = 6) or a control peptide Gly11 (n = 12) for 8 consecutive days. Doses of 0.2 mg/kg were administered subcutaneously 2x/day, at 10 AM and 6 PM. Blood pressure was measured by telemetry for 48 h before and during peptide infusion. Ventilation was assessed by whole-body barometric plethysmography, control of breathing was examined by assessing the hypoxic ventilatory response (HVR), and polysomnography was performed during light-phase at baseline and during treatment. Heart rate variability analyses were performed to estimate the cardiac autonomic balance. Systemic leptin receptor blockade with Allo-aca did not affect body weight, body temperature, and food intake in NZO mice. Plasma levels of leptin did not change after the treatment with either Allo-aca or the control peptide Gy11. NZO mice were hypertensive at baseline and leptin receptor blocker Allo-aca significantly reduced the mean arterial pressure from 134.9+- 3.1 to 124.9 +- 5.7 mmHg during the light phase (P < 0.05), whereas the control peptide had no effect. Leptin receptor blockade did not change the heart rate or cardiac autonomic balance. Allo-aca did not affect minute ventilation under normoxic or hypoxic conditions and HVR. Ventilation, apnea index, and oxygen desaturation during NREM and REM sleep did not change with leptin receptor blockade. Systemic leptin receptor blockade attenuates hypertension in NZO mice, but does not exacerbate obesity and SDB. Thus, leptin receptor blockade represents a potential pharmacotherapy for obesity-associated hypertension.

description: This study assessed how changes in BMI affected incident hypertension rates in Chinese adults. Data used was from the China Health and Nutrition Survey (CHNS), using samples from many provinces across China. Survival plots were generated to assess temporality of the outcome with respect to exposure. The results show that BMI grouping upon entry into the study was most effective at predicting whether the subject would develop hypertension.

description: It has been proved that the charged stringy black holes are stable under the perturbations of massive charged scalar fields. However, superradiant instability can be generated by adding the mirror-like boundary condition to the composed system of charged stringy black hole and scalar field. The unstable boxed quasinormal modes have been calculated by using both analytical and numerical method. In this paper, we further provide a time domain analysis by performing a long time evolution of charged scalar field configuration in the background of the charged stringy black hole with the mirror-like boundary condition imposed. We have used the ingoing Eddington-Finkelstein coordinates to derive the evolution equation, and adopted Pseudo-spectral method and the forth-order Runge-Kutta method to evolve the scalar field with the initial Gaussian wave packet. It is shown by our numerical scheme that Fourier transforming the evolution data coincides well with the unstable modes computed from frequency domain analysis. The existence of the rapid growth mode makes the charged stringy black hole a good test ground to study the nonlinear development of superradiant instability.
