description: The dynamics of growth of bacterial populations has been extensively studied for planktonic cells in well-agitated liquid culture, in which all cells have equal access to nutrients. In the real world, bacteria are more likely to live in physically structured habitats as colonies, within which individual cells vary in their access to nutrients. The dynamics of bacterial growth in such conditions is poorly understood, and, unlike that for liquid culture, there is not a standard broadly used mathematical model for bacterial populations growing in colonies in three dimensions (3-d). By extending the classic Monod model of resource-limited population growth to allow for spatial heterogeneity in the bacterial access to nutrients, we develop a 3-d model of colonies, in which bacteria consume diffusing nutrients in their vicinity. By following the changes in density of E.coli in liquid and embedded in glucose-limited soft agar, we evaluate the fit of this model to experimental data. The model accounts for the experimentally observed presence of a sub-exponential, diffusion-limited growth regime in colonies, which is absent in liquid cultures. The model predicts and our experiments confirm that, as a consequence of inter-colony competition for the diffusing nutrients and of cell death, there is a non-monotonic relationship between total number of colonies within the habitat and the total number of individual cells in all of these colonies. This combined theoretical-experimental study reveals that, within 3-d colonies, E.coli cells are loosely packed, and colonies produce about 2.5 times as many cells as the liquid culture from the same amount of nutrients. Our model provides a baseline description of bacterial growth in 3-d, deviations from which can be used to identify phenotypic heterogeneities and inter-cellular interactions that further contribute to the structure of bacterial communities.

DNP project: Evaluation of point-of-care ultrasound training program for certified registered nurse anesthetists
Creators: name: Dilks, Andrew

Year: 2023

description: Purpose of Project: Obtaining vascular access is an essential skill for every CRNA. Gaining access can be challenging in some patients, yet CRNA’s tend to use traditional methods, resulting in multiple failed sticks and delays in care. Literature supports using point-of-care ultrasound (POCUS) techniques to gain access in these patient populations. It also supports the efficacy of teaching POCUS using a didactic and a simulation component. The aim of this project was to decrease failed cannulation attempts by increasing POCUS use and to improve first attempt successful cannulation rate by CRNA’s for peripheral IV and A-line insertions.Methodology: This quality improvement project implemented a multimodal hands-on simulation ultrasound workshop for CRNA’s focusing on the Dynamic Needle Tip Positioning (DNTP) technique. Fifteen CRNA’s were given a didactic lecture, followed by a hands-on simulation workshop. During the workshop, participants used POCUS to identified vascular anatomy on humans and then cannulated a gelatin phantom model using the DNTP technique. Participants responded to pre- and post-workshop surveys. Results: Following the workshop, there was a significant increase in the number of times the CRNA’s used POCUS in the clinical setting to attempt vascular access (p=0.042). Additionally, participants successfully identified barriers to using ultrasound in their respective clinical settings. Some objectives were not met with statistical significance.Implications for Practice: Objectives that were not met and barriers that were identified will offer guidance for future scholarship development.

description: In this paper, we develop a new methodology to provide high assurance about privacy indicators in Cooperative Intelligent Transport Systems (C-ITS). Our focus lies on vehicle-to-everything (V2X) communications enabled by Cooperative Awareness Basic Service. Our research motivation is developed based on the analysis of unlinkability provision methods indicating a gap. To address this, we propose a Hidden Markov Model (HMM) to express unlinkability for the situation where two cars are communicating with a Roadside Unit (RSU) using Cooperative Awareness Messages (CAMs). Our HMM has labeled states specifying distinct origins of the CAMs observable by a passive attacker. We then demonstrate that a high assurance about the degree of uncertainty (e.g., entropy) about labeled states can be obtained for the attacker under the assumption that he knows actual positions of the vehicles (e.g., hidden states in HMM). We further demonstrate how unlinkability can be increased in C-ITS: we develop a joint probability distribution that both drivers must use to obfuscate their actual data jointly. This obfuscated data is then encapsulated in their CAMs. Finally, our findings are incorporated into an obfuscation algorithm whose complexity is linear in the number of discrete time steps in HMM.

description: AbstractPurpose of Project: The ability to obtain an emergency airway is an essential skill for all anesthe-sia providers. The Difficult Airway Algorithm (DAA) focuses on the management of difficult airways that are encountered with mask ventilation and endotracheal intubation, whether anticipated or unanticipated. When an anesthesia provider is unable to both mask ventilate or successfully en-dotracheally intubate after two attempts, it is referred to as a Can’t Ventilate Can’t Intubate (CVCI) event. A surgical airway is the last opportunity to produce a positive patient outcome, a skill that is neither practiced, nor frequently utilized in the field. Skill decay is a regularly reported problem because of the low occurrence high acuity nature of this scenario. Methodology: The State Professional Assembly conducted an airway workshop on difficult airway management. Upon entering, attendants were tasked with being able to re-cite the indications, contraindications and complications of a percutaneous cricothy-rotomy. Attendants were then asked to perform a percutaneous cricothyrotomy pre-intervention and evaluated using the same competency tools they would later be tested with to serve as a control. An educational audio-visual lecture as well as a hands-on presentation utilizing the simulated based mastery learning (SBML) method of instruction on 3D printed tracheal models was given to all attendants. Immediately following the block of instruction a post intervention teach-back as-sessment and likert scale to assess individual providers’ confidence level was im-plemented. Results: Both quantitative and descriptive analysis were performed on the data collected. A 2-Sample T Test as well as a Wilcoxon Signed Rank Test revealed a statistically significant difference between the pre and post intervention tests, indicating the SBML educational presentation better equipped the attendants on how to perform a percutaneous cricothyrotomy. A. A Cronbach’s Alpha was performed to prove in-ternal consistency of the study and replicability. Lastly a breakdown of scores was included with the pre and post intervention scores. On the pre-test only 33.3% of the attendants were able to make it past question 1, with 11% making it to question 10. Attendants received markedly improved test scores after the intervention as the pass rate was 100%.Implications for Practice: Hospitals are in need for easily accessible and affordable, pre-prepared lectures that will keep their anesthesia providers proficient and ready to in-tervene during CVCI scenarios. 3D printed larynx models can serve as an excellent surrogate for training that allows for life-like conditions when paired with SBML. Answering this knowledge gap will bring about quality and safety, educational, clinical practice implications later discussed within this paper.

description: A symmetry preserving framework for the study of continuum Quantum Chromodynamics (QCD) is obtained from a truncated solution of the QCD equations of motion or QCD's Dyson-Schwinger equations (DSEs). A nonperturbative solution of the DSEs enables the study of, e.g., hadrons as composites of dressed-quarks and dressed-gluons, the phenomena of confinement and dynamical chiral symmetry breaking (DCSB), and therefrom an articulation of any connection between them. It is within this context that we present a unified study of Nucleon, Delta and Roper elastic and transition form factors, and compare predictions made using a framework built upon a Faddeev equation kernel and interaction vertices that possess QCD-like momentum dependence with results obtained using a symmetry-preserving treatment of a vector$\,\otimes\,$vector contact-interaction.

description: The time-dependent optical properties of molecular systems are investigated by step-scan Fourier-transform spectroscopy in order to explore the dynamics at phase transitions and molecular orientation in the milli- and microsecond range. The electrical switching of liquid crystals traced by vibrational spectroscopy reveals a rotation of the molecules with a relaxation time of 2 ms. The photo-induced neutral-ionic transition in TTF-CA takes place by a suppression of the dimerization in the ionic phase and creation of neutral domains. The time-dependent infrared spectra depend on temperature and laser pulse intensity; the relaxation of the spectra follows a stretched-exponential decay with relaxation times in the microsecond range strongly dependent on temperature and laser intensity. We present all details of the experimental setups and thoroughly discuss the technical challenges.

description: Metal-insulator transitions in a three-component Falicov-Kimball model are investigated within the Kotliar-Ruckenstein slave boson mean-field approach. The model describes a mixture of two interacting fermion atom species loaded into an optical lattice at ultralow temperature. One species is two-component atoms, which can hop in the optical lattice, and the other is single-component atoms, which are localized. Different correlation-driven metal-insulator transitions are observed depending on the atom filling conditions and local interactions. These metal-insulator transitions are classified by the band renormalization factors and the double occupancies of the atom species. The filling conditions and the critical value of the local interactions for these metal-insulator transitions are also analytically established. The obtained results not only are in good agreement with the dynamical mean-field theory for the three-component Falicov-Kimball model but also clarify the nature and properties of the metal-insulator transitions in a simple physics picture.

description: Fathoming interplay between symmetry and topology of many-electron wave-functions has deepened understanding of quantum many body systems, especially after the discovery of topological insulators. Topology of electron wave-functions enforces and protects emergent gapless excitations, and symmetry is intrinsically tied to the topological protection in a certain class. Namely, unless the symmetry is broken, the topological nature is intact. We show novel interplay phenomena between symmetry and topology in topological phase transitions associated with line-nodal superconductors. The interplay may induce an exotic universality class in sharp contrast to that of the phenomenological Landau-Ginzburg theory. Hyper-scaling violation and emergent relativistic scaling are main characteristics, and the interplay even induces unusually large quantum critical region. We propose characteristic experimental signatures around the phase transitions in three spatial dimensions, for example, a linear phase boundary in a temperature-tuning parameter phase-diagram.

description: This thesis discusses the prison abolitionist cultural productions of queer and trans of color artists and theorists who have in some way engaged with the University of Texas at Austin’s Center for Women’s and Gender Studies. I argue that with the use of storytelling and dreamwork methodologies, each of these artists and thinkers enacts an abolitionist worldbuilding that proves us with a blueprint for how to enact a non-carceral queer and trans futurity. The thesis discusses two films, Criminal Queers and Major!, to think about the ways that queer and trans people of color engage in fugitive and errant moves to circumvent carceral logics and the surveillant gaze of the state. I later discuss the archival works of Danielle Brathwaite-Shirley in connection with abolitionist theorizing by Mariame Kaba and José Esteban Muñoz. Throughout the thesis I ask questions about futurity and healing, and position artists within and outside the academy as both producing rich and destabilizing theory that helps us better understand prison abolition as a methodology and a dream.

description: Human society faces increasingly complex problems that require coordinated collective action. Artificial intelligence (AI) holds the potential to bring together the knowledge and associated action needed to find solutions at scale. In order to unleash the potential of human and AI systems, we need to understand the core functions of collective intelligence. To this end, we describe a socio-cognitive architecture that conceptualizes how boundedly rational individuals coordinate their cognitive resources and diverse goals to accomplish joint action. Our transactive systems framework articulates the inter-member processes underlying the emergence of collective memory, attention, and reasoning, which are fundamental to intelligence in any system. Much like the cognitive architectures that have guided the development of artificial intelligence, our transactive systems framework holds the potential to be formalized in computational terms to deepen our understanding of collective intelligence and pinpoint roles that AI can play in enhancing it.
Mindfulness meditation to reduce scan-associated anxiety in oncology patients
Creators: name: Costello, Maureen
Publisher: name: No Publisher Supplied
Year: 2023

description: Purpose of Project: Anxiety surrounding imaging appointments is a common phenomenon among oncology patients. Positron emission tomography (PET) and computed tomography (CT) scans are used for the diagnosis and staging of disease in oncology patients, leading to anticipatory anxiety before scans. Mindfulness based interventions are an exciting and promising innovation that have shown success in reducing anxiety levels in various settings, including oncology. The purpose of this project is to evaluate the effect of a brief mindfulness meditation audio recording on scan-associated anxiety levels in oncology patients. Methodology: This project was conducted in the radiology waiting room of an outpatient cancer center in Northern New Jersey for oncology patients scheduled for same day PET or CT scans. The Generalized Anxiety Disorder-7 (GAD-7) screening tool was used to measure baseline anxiety levels. The Visual Analog Scale for Anxiety (VAS-A) was implemented before and after a mindfulness meditation recording to assess its effect on patient anxiety levels. Results: All participants reported some degree of anxiety and 33% had moderate or severe anxiety levels. Results showed high patient satisfaction with 67% of participants identifying the intervention as helpful. While the results did not have statistical significance, 50% of patients showed reductions in their anxiety levels which is clinically significant. Implications for Practice: Anxiety is a clinical problem for oncology patients as evidenced by the mean GAD-7 and VAS-A results. There was interest in the project as evidenced by the 30 patients who scanned the QR code, but the majority did not meet eligibility criteria. Patients who found it helpful might practice mindfulness techniques in different stressful situations. This project has the potential to be successful in reducing scan-associated anxiety but should be replicated on a larger scale to better understand the clinical impact.

How plausible are the proposed formation scenarios of CEMP-r/s stars?

description: CEMP-$r/s$ stars are metal-poor stars with enhanced abundances of carbon and heavy elements associated with the slow ($s$-) and rapid ($r$-) neutron-capture process. It is believed that carbon and $s$-elements were accreted from the wind of an AGB primary star, a scenario that is generally accepted to explain the formation of CEMP stars that are only enhanced in $s$-elements (CEMP-$s$ stars). The origin of $r$-element-enrichment in CEMP-$r/s$ stars is debated and many formation scenarios have been put forward. We aim to determine the likelihood of the scenarios proposed to explain the formation of CEMP-$r/s$ stars. We calculate the frequency of CEMP-$r/s$ stars among CEMP-$s$ stars for a variety of scenarios, and we compare it with that determined from an observed sample of CEMP-$r/s$ stars collected from the literature. The theoretical frequency of CEMP-$r/s$ stars predicted in most scenarios underestimates the observed ratio by at least a factor of 5. If the enrichments in $s$- and $r$-elements are independent, the model ratio of CEMP-$r/s$ to CEMP-$s$ stars is about 22%, that is approximately consistent with the lowest estimate of the observed ratio. However, this model predicts that about one third of all carbon-normal stars have [Ba/Fe] and [Eu/Fe] higher than 1, and that 40% of all CEMP stars have [Ba/Eu]$\le0$. Stars with these properties are at least ten times rarer in our observed sample. The $intermediate$ or $i$-process, which is supposedly active in some circumstances during the AGB phase, could provide an explanation of the origin of CEMP-$r/s$ stars, similar to that of CEMP-$s$ stars, in the context of wind mass accretion in binary systems. Further calculations of the nucleosynthesis of the $i$-process and of the detailed evolution of late AGB stars are needed to investigate if this scenario predicts a CEMP-$r/s$ star frequency consistent with the observations.

description: Pd(100) ultrathin films show ferromagnetism induced by the confinement of electrons in the film, i.e., the quantum-well mechanism. In this study, we investigate the effect of the change in the interface structure between a Pd film and SrTiO3 substrate on quantum-well induced ferromagnetism using the structural phase transition of SrTiO3. During repeated measurement of temperature- dependent magnetization of the Pd/SrTiO3 system, cracks were induced in the Pd overlayer near the interface region by the structural phase transition of SrTiO3, thereby changing the film-thickness dependence of the magnetic moment. This is explained by the concept that as the magnetic moment in Pd(100) changed, so too did the thickness of the quantum-well. In addition, we observed that the ferromagnetism in the Pd(100) disappeared with the accumulation of cracks due to the repetition of the temperature cycle through the phase-transition temperature. This suggests that lowering the crystallinity of the interface structure by producing a large number of cracks has a negative effect on quantum-well induced ferromagnetism.

description: In this paper we deal with linear production situations in which there is a limited common-pool resource, managed by an external agent. The profit that a producer, or a group of producers, can attain depends on the amount of common-pool resource obtained through a certain procedure. We contemplate a competitive process among the producers or groups of producers and study the corresponding non cooperative games, describing their (strict) Nash equilibria in pure strategies. It is shown that strict Nash equilibria form a subset of strong Nash equilibria, which in turn form a proper subset of Nash equilibria.

Far-field resonance fluorescence from a dipole-interacting laser-driven cold atomic gas

description: We analyze the temporal response of the fluorescence light that is emitted from a dense gas of cold atoms driven by a laser. When the average interatomic distance is smaller than the wavelength of the photons scattered by the atoms, the system exhibits strong dipolar interactions and collective dissipation. We solve the exact dynamics of small systems with different geometries and show how these collective features are manifest in the scattered light properties such as the photon emission rate, the power spectrum and the second-order correlation function. By calculating these quantities beyond the weak driving limit, we make progress in understanding the signatures of collective behavior in these many-body systems. Furthermore, we clarify the role of disorder on the resonance fluorescence, of direct relevance for recent experimental efforts that aim at the exploration of many-body effects in dipole-dipole interacting gases of atoms.

description: While global cosmological and local galactic abundance of dark matter is well established, its identity, physical size and composition remain a mystery. In this paper, we analyze an important question of dark matter detectability through its gravitational interaction, using current and next generation gravitational-wave observatories to look for macroscopic (kilogram-scale or larger) objects. Keeping the size of the dark matter objects to be smaller than the physical dimensions of the detectors, and keeping their mass as free parameters, we derive the expected event rates. For favorable choice of mass, we find that dark matter interactions could be detected in space-based detectors such as LISA at a rate of one per ten years. We then assume the existence of an additional Yukawa force between dark matter and regular matter. By choosing the range of the force to be comparable to the size of the detectors, we derive the levels of sensitivity to such a new force, which exceeds the sensitivity of other probes in a wide range of parameters. For sufficiently large Yukawa coupling strength, the rate of dark matter events can then exceed 10 per year for both ground- and space-based detectors. Thus, gravitational-wave observatories can make an important contribution to a global effort of searching for non-gravitational interactions of dark matter.
Holographic partition functions and phases for higher genus Riemann surfaces

description: We describe a numerical method to compute the action of Euclidean saddlepoints for the partition function of a two-dimensional holographic CFT on a Riemann surface of arbitrary genus, with constant curvature metric. We explicitly evaluate the action for the saddles for genus two and map out the phase structure of dominant bulk saddles in a two-dimensional subspace of the moduli space. We discuss spontaneous breaking of discrete symmetries, and show that the handlebody bulk saddles always dominate over certain non-handlebody solutions.

description: El objetivo de este trabajo es establecer una relación entre Literatura y Economía, planteando cuatro principios económicos universales planteados por Gregory Mankiw, que se ven reflejados en el libro Ficciones Cotidianas, pretendemos analizar cómo miran los narradores y personajes la relación: sujeto-ciudad-economía en el discurrir de los hechos narrados y en la toma de decisiones. De igual forma, abordaremos cómo es manejado el espacio en la ciudad propuesta por Carlo Morales, la dinamicidad de ellos o no, con personajes o sin ellos. La economía, aunque es de muchos modos un ente virtual, ya que no es algo tangible, se representa físicamente y perfectamente en la ciudad, en los espacios llenos de objetos, y en muchos casos, de personas o personajes. Seguidamente, miraremos la relación indisoluble entre Economía y ciudad y cómo se presenta esta relación en los distintos espacios de la ciudad latinoamericana. Por consiguiente, este trabajo manifiesta cómo se encuentran representados el espacio público y el espacio privado, que son determinantes para construir la cosmovisión plasmada en los relatos de la ciudad contemporánea.

description: Thermal expansion, electrical resistivity, magnetization, and specific heat measurements were performed on URu$_{2-x}$Fe$_{x}$Si$_{2}$ single crystals for various values of the Fe concentration $x$ in both the hidden order (HO) and large moment antiferromagnetic (LMAFM) regions of the phase diagram. Our results show that the paramagnetic (PM) to HO and LMAFM phase transitions are manifested differently in the thermal expansion coefficient. For Fe concentrations near the boundary between the HO and LMAFM phases at $x_c$ ~ 0.1, we observe two features in the thermal expansion upon cooling, one that appears to be associated with the transition from the PM to the HO phase and another one at lower temperature that may be due to the transition from the HO to the LMAFM phase. These two features have not been observed in other measurements such as specific heat or neutron scattering. In addition, the uniaxial pressure derivative of the transition temperature, based on a calculation using thermal expansion and specific heat data, changes dramatically when crossing from the HO to the LMAFM phase.
