Energy Dependence of Transverse Momentum Correlations and an Exploration of the Color String Percolation Model in AuAu Collisions

Garand, David M. PhD, Purdue University, December 2015. Energy Dependence of Transverse Momentum Correlations and an Exploration of the Color String Percolation Model in AuAu Collisions. Major Professor: Andrew Hirsch. The Relativisic Heavy Ion Collider (RHIC) conducted a two year beam energy scan (BES I) to provide data for AuAu collisions at 7.7, 11.5, 19.6, 27, 39, 62.4, and 200 GeV. The motivation for this scan was to search for the phase transition critical point between normal matter and the quark gluon plasma (QGP). This thesis reports on two analyses that attempt to directly search for such a critical point. Data from the Solenoidal Tracker at RHIC (STAR) was analyzed for this study, and included pp collisions at 62 and 200 GeV, and AuAu collisions at 7.7, 11.5, 19.6, 27, 39, 62.4, and 200 GeV. The Color String Percolation Model (CSPM) provides a method for extracting an initial temperature for collisions by fitting the transverse momentum (pT ) spectrum created from a sample of events of a given energy and centrality. In order to search for fluctuations in temperature, this thesis explores applying the CSPM to single events in order to create a distribution of temperatures for collisions of a given energy. Applying this method to the BES I data allows a search for an increase in temperature fluctuations indicative of the critical point. To gauge the accuracy of these measurements, the first systematic study of applying the CSPM to data is reported. The two particle transverse momentum correlator has previously been used to search for fluctuations in pT that could be indicative of the critical phase transition point. The BES I energies were specifically studied in reference [1]. An interesting behavior of the pT spectrum was noted at lower energies in that work, and in this
What Determinants Make Internship Intention to Join the Hospitality Industry

Retaining the program from the campus so that you can enjoy for the first time the way to practice in work, which may be referred to as internship work, offers college students an idea of running in the industry. Within internships performed by college students, there are numerous factors to attain satisfaction in an internship, one among which is the element of social support within the painting's surroundings. Consequently, this examination discusses the influence of social assistance on internship pleasure which affects the goal of signing up for the hospitality industry of college students who carry out internships in 4-stars hotels. This research uses quantitative techniques and judgemental sampling techniques. Primary data collection is information collected by distributing questionnaires to students of private universities in the Jakarta and Banten areas who did internships at four-star hotels within the Jakarta and Banten regions. The data amassed became 183 respondents. The data obtained is processed using the Structural Equation Modeling (SEM) method. The outcomes showed that perceived supervisor support and coworker support positively impacted Internship satisfaction, and perceived organizational support did not affect Internship satisfaction. Internship satisfaction impacts the intention to join the hospitality industry.
Study on the Continued Use Intention of Comprehensive Booking Tourist APP—The Moderating Effect of the Big Five Personality Traits

: A theoretical model based on the UTAUT 2 model was developed to explore the influencing factors of sustained use intention of a comprehensive booking travel app and to explore the moderating effect of the Big Five personality. The results show that user satisfaction is influenced by need satisfaction, effort expectation and perceived quality, and continued use intention is influenced by the other four variables except perceived quality; satisfaction has a mediating role; all four personality traits have a moderating effect except openness. This study provides theoretical references for the personalized development and design of comprehensive booking travel APPs, promoting users' continuous use and tourism marketing.
Applications of Complex Multiplication of Elliptic Curves

We start by recalling and discussing the tools that we will need later on: topics will cover modular forms, ramification theory, orders and quadratic forms. This will enable us to introduce the Hilbert class field and the Hilbert class polynomial, which will be useful in later chapters. Since this is just some preparing material for our main topics of elliptic curves and complex multiplication, proofs will be in general omitted and references will be given. 1.1 Modular Forms and j-function We start by considering the special linear group SL2(Z), that is the group of all 2× 2 matrices with determinant 1 and integer coefficients SL2(Z) := {( a b c d ) | a, b, c, d ∈ Z, ad− bc = 1 } An element ( a b c d ) of SL2(Z) acts on a complex number z by ( a b c d ) · z = az + b cz + d Remark 1.1.1. The quotient Γ := SL2(Z)/{±I} is called the modular group (observe that {±I} is the center of SL2(Z)). This is also referred to as SL2(Z), the special linear group.
Bone Marrow Derived Cells Mediated Regulation of Schwann Cells Proliferation and Migration In vitro

Schwann cells (SCs) are the unique glial cells in the peripheral nerve. After peripheral nerve injury, SCs change their morphology, function, and play a new role as repair cells, through this process, factors that enhance SCs proliferation and promote SCs migration will benefit nerve regeneration and functional recovery. Bone marrow-derived cells (BMDCs), which has been proved to offer several regenerative benefits for tissue and organ injuries. However, whether BMDCs support nerve regeneration by affect the proliferation and migration of SCs, remains unclear. Here, we taken BMDCs co-cultured with nerve segments, and then investigated the proliferation and migration of SCs In vitro. Results demonstrated that BMDCs can enhance the proliferation of SCs, and then promoted SCs migration, forming Bungner’s brand-liked structure In vitro. These finding provide a potential new method for repair of injured peripheral nerves in clinical.
TIPP 2011 - Technology and Instrumentation for Particle Physics 2011 An Apparatus to Search for Neutrinoless Double Beta Decay

The NEMO-3 (Neutrino Ettore Majorana Observatory) experiment, located in the Modane Underground Laboratory, searches for neutrinoless double beta decay. The experiment has been taking data since 2003 with seven double beta isotopes and completed data acquisition in January 2011. Two neutrino double beta decay results for the main isotopes (7 kg of 100 Mo and 1 kg of 82 Se), new results for 150 Nd and 130 Te, as well as results for 96 Zr and 48 Ca are presented. NEMO-3 uses a unique technique that allows for the in situ measurement of background contamination. No evidence for neutrinoless double beta decay has been found to date. The data are also interpreted in terms of alternative models such as weak right-handed currents and Majoron emission. In this proceeding, I discussed the measurements made with NEMO-3 and discussed the status, research and design of the next generation experiment, SuperNEMO.
Chimp Optimized Fractional-Order Tilt Integral Derivative Controller (NFO-TIDC) Assisted Battery for EV Charging

Abstract The vast usage of electric vehicles (EVs) has raised to minimize the dependency on fossil fuels. The Photovoltaic (PV) is used in the charging station to supply the required power to the EV. Batteries’ charging and discharging control have become a major challenge in RES interconnected EV charging stations. To tackle this issue, a novel fractional-order tilt integral derivative controller (NFO-TIDC) is used in the battery-connected bidirectional converter. Moreover, special considerations of the NFO-TIDC are accomplished with an improved Chimp optimization algorithm. In addition, the enhanced seagull optimized maximum power tracking controller has been proposed for maximizing the power from PV under varying irradiance. The proposed method is implemented on MATLAB/Simulink, and the obtained results verify the superiority of the controller.
Design of Semi Automatic Announcement System In The Public Address System Part of The Main Branch Office Soekarno-Hatta International Airport Angkasa Pura II, Inc

Facilities and services are needed reliable for the comfort of airplane passengers. One of the important facilities in airport services is the Public Address System (PAS). PAS is a notification system using sound electronically distributed with amplifiers, loudspeakers, and microphones. PAS functions to provide information from the airport and airlines to be conveyed widely to airplane passengers. In order to reduce the possibility of misinformation or delivery of unclear information from the operator, the author aims to create Semi Automatic Announcement System (AAS) website where someone no longer needs to speak directly but only needs to enter a notification sentence, then the system from the website will speak or also can be referred to as text to speech. The system is expected to reduce misinformation so that information can be clearly understood by passengers.
Characteristics and phenotypes of a COPD cohort in Uganda.

Introduction: Chronic Obstructive Pulmonary Disease (COPD) is a heterogeneous condition with varied clinical and pathophysiologic characteristics. Although there is increasing evidence that COPD in low- and middle-income countries may have different clinical characteristics from that in high income countries, little is known about COPD phenotypes in these settings. We describe the clinical characteristics and risk factor profile of a COPD population in Uganda. Methods: We cross sectionally analyzed the baseline clinical characteristics of 323 COPD patients aged 30 years and above who were attending two national referral outpatient facilities in Kampala, Uganda between July 2019 and March 2021. Logistic regression was used to determine factors associated with spirometric disease severity. Results: The median age was 62 years; 51.1% females; 93.5% scored CAT >10; 63.8% mMRC >2; 71.8% had wheezing; 16.7% HIV positive; 20.4% had a history of pulmonary tuberculosis; 50% with blood eosinophilic count >3%, 51.7% had 3 or more exacerbations in the past year. Greater severity by GOLD stage was inversely related to age, (aOR=0.95, 95%CI=0.92, 0.97), and obesity compared to underweight (aOR=0.25, 95%CI=0.07, 0.82). Regarding clinical factors, more severe airflow obstruction was associated with SPO2<93% (aOR=3.79, 95%CI=2.05, 7.00), mMMRC[≥]2 (aOR=2.21, 95%CI=1.08, 4.53), and a history of severe exacerbations (aOR=2.64, 95%CI=1.32, 5.26). Conclusion: COPD patients in this population had specific characteristics and risk factor profiles including HIV and TB meriting tailored preventative approaches. Further studies are needed to better understand the pathophysiological mechanisms at play and the therapeutic implications of these findings.
Divergent foraging strategies between populations of sympatric matrilineal killer whales

Abstract In cooperative species, human-induced rapid environmental change may threaten cost–benefit tradeoffs of group behavioral strategies that evolved in past environments. Capacity for behavioral flexibility can increase population viability in novel environments. Whether the partitioning of individual responsibilities within social groups is fixed or flexible across populations is poorly understood, despite its relevance for predicting responses to global change at the population and species levels and designing successful conservation programs. We leveraged bio-logging data from two populations of fish-eating killer whales (Orcinus orca) to quantify patterns of fine-scale foraging movements and their relationships with demography. We reveal striking interpopulation differences in patterns of individual foraging behavior. Females from the endangered Southern Resident (SRKW) population captured less prey and spent less time pursuing prey than SRKW males or Northern Resident (NRKW) females, whereas NRKW females captured more prey than NRKW males. The presence of a calf (≤3 years) reduced the number of prey captured by adult females from both populations, but disproportionately so for SRKW. SRKW adult males with a living mother captured more prey than those whose mother had died, whereas the opposite was true for NRKW adult males. Across populations, males foraged in deeper areas than females, and SRKW captured prey deeper than NRKW. These population-level differences in patterns of individual foraging behavior challenge the existing paradigm that females are the disproportionate foragers in gregarious resident killer whales, and demonstrate considerable variation in the foraging strategies across populations of an apex marine predator experiencing different environmental stressors.
Nest material preferences in wild hazel dormice Muscardinus avellanarius: testing predictions from optimal foraging theory

Abstract Obtaining nesting material presents an optimal foraging problem, collection of materials incurs a cost in terms of risk of predation and energy spent and individuals must balance these costs with the benefits of using that material in the nest. The hazel dormouse, Muscardinus avellanarius is an endangered British mammal in which both sexes build nests. However, whether material used in their construction follows the predictions of optimal foraging theory is unknown. Here, we analyze the use of nesting materials in forty two breeding nests from six locations in Southwest England. Nests were characterized in terms of which plants were used, the relative amount of each plant, and how far away the nearest source was. We found that dormice exhibit a preference for plants closer to the nest, but that the distance they are prepared to travel depends on the plant species. Dormice traveled further to collect honeysuckle Lonicera periclymenum, oak Quercus robur, and beech Fagus sylvatica than any other plants. Distance did not affect the relative amount used, although the proportion of honeysuckle in nests was highest, and more effort was expended collecting honeysuckle, beech, bramble Rubus fruticosus and oak compared to other plants. Our results suggest that not all aspects of optimal foraging theory apply to nest material collection. However, optimal foraging theory is a useful model to examine nest material collection, providing testable predictions. As found previously honeysuckle is important as a nesting material and its presence should be taken account when assessing suitability of sites for dormice.
Integrated optical Ti:Er:LiNbO/sub 3/ soliton source

Efficient diode-pumped and harmonically mode-locked operation of a fully packaged Ti:Er:LiNbO/sub 3/ waveguide laser at 1562- (TE) and 1575-nm (TM) wavelength has been demonstrated. The mode-locked pulses have been characterized in terms of time-bandwidth product, fine tuning, and stability. Noise suppression of 42 dB at the relaxation oscillation frequency has been achieved by feedback-controlled pumping. An external amplitude modulator has been used for encoding of the mode-locked pulse train with different bit sequences. Bit error rates of 10/sup -10/ for a 1-0-1-0-bit sequence has been observed for more than half an hour.
Factors Affecting the Gut Microbiome in Pediatric Intestinal Failure

Background: There is little data on gut microbiome and various factors that lead to dysbiosis in pediatric intestinal failure (PIF). This study aimed to characterize gut microbiome in PIF and determine factors that may affect microbial composition in these patients. Methods: This is a single-center, prospective cohort study of children with PIF followed at our intestinal rehabilitation program. Stool samples were collected longitudinally at regular intervals over a 1-year period. Medical records were reviewed, and demographic and clinical data were collected. Medication history including the use of acid blockers, scheduled prophylactic antibiotics, and bile acid sequestrants was obtained. Gut microbial diversity among patients was assessed and compared according to various host characteristics of interest. Results: The final analysis included 74 specimens from 12 subjects. Scheduled prophylactic antibiotics, presence of central line associated bloodstream infection (CLABSI) at the time of specimen collection, use of acid blockers, and ≥50% calories delivered via parenteral nutrition (PN) was associated with reduced alpha diversity, whereas increasing age was associated with improved alpha diversity at various microbial levels (P value <0.05). Beta diversity differed with age, presence of CLABSI, use of scheduled antibiotics, acid blockers, percent calories via PN, and presence of oral feeds at various microbial levels (P value <0.05). Single taxon analysis identified several taxa at several microbial levels, which were significantly associated with various host characteristics. Conclusion: Gut microbial diversity in PIF subjects is influenced by various factors involved in the rehabilitation process including medications, percent calories received parenterally, CLABSI events, the degree of oral feeding, and age. Additional investigation performed across multiple centers is needed to further understand the impact of these findings on important clinical outcomes in PIF.
Lower-limb wearable resistance overloads joint angular velocity during early acceleration sprint running

ABSTRACT Lower-limb wearable resistance (WR) facilitates targeted resistance-based training during sports-specific movement tasks. The purpose of this study was to determine the effect of two different WR placements (thigh and shank) on joint kinematics during the acceleration phase of sprint running. Eighteen participants completed maximal effort sprints while unloaded and with 2% body mass thigh- or shank-placed WR. The main findings were as follows: 1) the increase to 10 m sprint time was small with thigh WR (effect size [ES] = 0.24), and with shank WR, the increase was also small but significant (ES = 0.33); 2) significant differences in peak joint angles between the unloaded and WR conditions were small (ES = 0.23–0.38), limited to the hip and knee joints, and <2° on average; 3) aside from peak hip flexion angles, no clear trends were observed in individual difference scores; and, 4) thigh and shank WR produced similar reductions in average hip flexion and extension angular velocities. The significant overload to hip flexion and extension velocity with both thigh- and shank-placed WR may be beneficial to target the flexion and extension actions associated with fast sprint running.
Independent short- and long-term dependencies in perception

Abstract Perception is biased by stimulus history. Both long-term effects such as the central-tendency bias (CTB) and short-term effects such as serial dependence (SD) have been described, but research into the two has remained largely separate. The sources of these effects, however, are highly correlated in stimulus statistics, which can result in a misinterpretation of experimental data. We compared CTB and SD in the perception of color and line length. Observers judged the relative hue or length of consecutive stimuli in a delayed-matching task. Two interstimulus intervals were used to investigate whether elapsed time or the number of stimulus occurrences was more important for SD. We estimated biases by fitting psychometric functions to the data split based on the history features, and we also fit generalized linear mixed models with either CTB, SD, or both included as regressors. We found biases to both recent stimulus history and the cumulative average of stimulus values for both color and line length judgments. The strength and pattern of each of the biases depended on whether all sources of bias were included in the analysis. Within the range of interstimulus intervals tested, the number of intervening stimuli was more important than elapsed time for SD. We conclude that both SD and CTB independently affect perceptual judgments, and that one effect is not an artifact caused by the other. Failing to consider both effects in data analysis can give an erroneous picture of the phenomenon under study.
Modifications of the pion-production threshold in the nuclear medium in heavy ion collisions and the nuclear symmetry energy

Using the relativistic Vlasov-Uehling-Uhlenbeck (RVUU) equation based on mean fields from the nonlinear relativistic NL ρ and NL ρ δ models, which have same nuclear equation of state and symmetry energy but different symmetry energy slope parameters, we study the effect of medium modification of the pion-production threshold on the total pion yield and the π − / π + ratio in Au+Au collisions. We find that the in-medium threshold effect enhances both the total pion yield and the π − / π + ratio, compared to those without this effect. Furthermore, including the medium modification of the pion-production threshold leads to a larger π − / π + ratio for the NL ρ δ model with a larger symmetry energy parameter than the NL ρ model with a smaller symmetry energy parameter, opposite to that found without the in-medium threshold effect. To reproduce the total pion yield measured by the FOPI Collaboration, we introduce a density-dependent cross section for Δ baryon production from nucleon-nucleon collisions, which suppresses the total pion yield but hardly changes the π − / π + ratio. Because of the small difference in the stiffness of their symmetry energies, the π − / π + ratios obtained from both the NL ρ and NL ρ δ models are consistent with the FOPI data within the experimental errors.
Indistinguishable of AES-Based PRNG against Modification Attack Based on Statistical Distance Tests and Entropy Measures

 Abstract —Due to previous research, AES-based PRNG is not affected by insertion attack (in random manner) under level of significant α = 0.01, even it caused some failed tests in randomness. Completing the research, the writers do the observation of the modification attack in random manner against the output sequence of AES-based PRNG that is limited to 1-bit modification attack. The tests are performed by applying statistical distance test between the output sequence before and after the attack. To assure the attack effect, we also measure the entropy values of the sequence before and after attack and compare them. The attack scenario is still the same as the previous research [see 3], except replacing the insertion with modification and parameter  = 0.001. The results show that the modification attack does not give the significant effect on the randomness property of the AES-based PRNG. It was proved from 60 experiments of 1-bit modification attack, that the maximum statistical distances are still far away from  = 0.001. And the change of the entropy source after the attack are very small and also still far away from the  = 0.001.
