description: A highly convergent, enantioselective total synthesis of brevetoxin A is reported. The development of a [X + 2 + X] Horner–Wadsworth–Emmons/cyclodehydration/reductive etherification convergent coupling strategy allowed for a unified approach to the synthesis of two advanced tetracyclic fragments from four cyclic ether subunits. The Horner–Wittig coupling of the two tetracyclic fragments provided substrates that were explored for reductive etherification, the success of which delivered a late-stage tetraol intermediate. The tetraol was converted to the natural product through an expeditious selective oxidative process, followed by methylenation.

description: Brevetoxin A is a decacyclic ladder toxin that possesses five-,six-, seven-, eight-, and nine-membered oxacycles, as well as 22 tetrahedral stereocenters. Herein, we describe a unified approach to the B, E, G, and J rings predicated upon a ring-closing metathesis strategy from the corresponding dienes. The enolate technologies developed in our laboratory allowed access to the precursor acyclic dienes for the B, E, and G medium ring ethers. The strategies developed for the syntheses of these four monocycles ultimately provided multigram quantities of each of the rings, supporting our efforts toward the convergent completion of brevetoxin A.
Effective theory for the non-rigid rotor in an electromagnetic field: Toward accurate and precise calculations of E2 transitions in deformed nuclei

description: We present a model-independent approach to electric quadrupole transitions of deformed nuclei. Based on an effective theory for axially symmetric systems, the leading interactions with electromagnetic fields enter as minimal couplings to gauge potentials, while subleading corrections employ gauge-invariant non-minimal couplings. This approach yields transition operators that are consistent with the Hamiltonian, and the power counting of the effective theory provides us with theoretical uncertainty estimates. We successfully test the effective theory in homonuclear molecules that exhibit a large separation of scales. For ground-state band transitions of rotational nuclei, the effective theory describes data well within theoretical uncertainties at leading order. In order to probe the theory at subleading order, data with higher precision would be valuable. For transitional nuclei, next-to-leading order calculations and the high-precision data are consistent within the theoretical uncertainty estimates. We also study the faint inter-band transitions within the effective theory and focus on the $E2$ transitions from the $0^+_2$ band (the "$β$ band") to the ground-state band. Here, the predictions from the effective theory are consistent with data for several nuclei, thereby proposing a solution to a long-standing challenge.

description: Abstract:

La produzione bellica e la sua organizzazione hanno rappresentato un aspetto importante della prima guerra mondiale durante la quale si sono sviluppati numerosi gruppi imprenditoriali italiani, alcuni dei quali vengono accusati nel dopoguerra di aver lucrato indebitamente sulle forniture belliche. Tra il 1920 e il 1923 la Commissione parlamentare d’inchiesta sulle spese di guerra indagherà sui sovrapprofitti e svelerà gli opachi rapporti tra Stato e industria creatisi tra il 1915 e il 1918. Grazie al fondo omonimo è possibile così analizzare il fenomeno di alcuni di questi lucri illeciti e approfondire lo studio di alcune delle trasformazioni in atto al tempo. Attraverso due casi di studio, sull’industria aeronautica e sul panno grigio verde, si vuole così ricostruire non solo l’origine dei sovrapprofitti ma anche alcune ripercussioni che questi ‘illeciti guadagni’ ebbero nel dopoguerra e sul sistema economico italiano.

Abstract:

Military production and its organization have represented an important feature of World War One. During World War One many Italian companies have developed, and in the post-war period some of them have been accused of having illegally profited by military supplies. From 1920 to 1923 the Commissione parlamentare d’inchiesta sulle spese di guerra look ed into the ‘over-profit’, and revealed the veiled relations established between the Government and industry during the period between 1915 and 1918. Thanks to the documents collection of the same name, it is possible to examine some illegal profit cases and to investigate some of the changes that happened at the time. In analyzing two case studies, about Italian Aeronautical industry and the gray green cloth, the aims to reconstruct not only the origin of over-profit, but also some of the consequences that this illegal profit had in the postwar period and on the Italian industrial and economic system.

Influence of seabird nutrient input on intertidal ecology in the Farne Islands, Northumberland

description: Seabirds are keystone species, providing inter-habitat connectivity by transporting vast quantities of nutrients from their pelagic feeding grounds to terrestrial and marine ecosystems, dictating community structure and dynamics, and providing multiple ecosystem services. This flow of nutrients is being disrupted by human activities, such as invasive species, and seabirds are now one of the most threatened bird groups. Whether seabird nutrients are cycling through nearshore, temperate systems, in particular in the United Kingdom (UK), impacting biodiversity and productivity, and how these inputs may vary temporally, remains unknown. The impact of nutrient subsidies to the Farne Islands, Northumberland, areas of high seabird densities during breeding season, was compared to nearby low seabird density areas on the Northumberland coast. Seabird densities and nitrogen inputs of up to 2334 and 1054 times higher, respectively, on seabird islands resulted in both substantially enriched nitrogen stable isotope (δ15N) values and higher total nitrogen content in terrestrial and intertidal organisms, including soil, terrestrial plants, lichen, barnacles, and limpets, and just higher δ15N values in macroalgae and turf algae. Temporal variation was also detected, though, surprisingly, nitrogen loads were higher during early breeding season. Some support was found for increased biodiversity in intertidal areas of seabird islands, in higher densities of intertidal predators and marginally greater algal species richness, though diversity differences were small overall. A marginal difference in limpet size was found, whilst on plots artificially cleared to simulate a disturbance event, barnacles were unexpectedly found to recolonise faster on mainland sites, which was likely caused by the mainland’s increased exposure level. These findings provide evidence that seabirds are cycling pelagic nutrients into terrestrial and intertidal ecosystems on UK islands, though support for seabird nutrient input increasing biodiversity and productivity was mixed. Given the threats to seabirds globally, these findings promote seabird conservation, including the removal of invasive species, such as rat eradication programmes.

Moral Distress in the Critical Care Setting
Creators: name: May, Aaron
Publisher: name: The University of North Carolina at Chapel Hill University Libraries
Year: 2023

description: Abstract


Introduction: Moral distress occurs when doing what is typically considered the right thing to do is impossible because of internal and/or external constraints. Nurses experience moral distress daily in practice due to the rigor yet empathetic nature of the career. Situations such as feeling pressured to carry out unnecessary orders or care for patients whom one does not feel qualified to care for are example of situations that produce moral distress within nurses (Epstein, et. al., 2019). Consequentially, continual exposure of nurses to moral distress have led many to leave their positions or the field of nursing entirely. 

Methods: A quantitative, descriptive study was conducted through the AACN Participate in Research website to recruit critical care nurses that practiced during the COVID-19 pandemic. Utilizing the Measure of Moral Distress for Healthcare Professionals (MMD-HP) scale participants voluntarily complete demographic, survey, and open-ended questions that evaluate their experiences with moral distress. 

Result: Based on the ten responses, 90% of the participants expressed thoughts of leaving their position at one point in time due to moral distress, with two of those participants actually leaving their job. Additionally, 30% of the participants reported their employers offered no support for dealing with moral distress during the COVID-19 pandemic. 

Conclusion: Moral distress is an important consideration to improve the work experience for critical care nurses, and address the concerns that may drive nurses to leave their positions and/or leave the profession.

Quantum engineering for compactly localized states in disordered Lieb lattices

description: Blending ordering within an uncorrelated disorder potential in families of 3D Lieb lattices preserves the macroscopic degeneracy of compact localized states and yields unconventional combinations of localized and delocalized phases -- as shown in Phys.Rev.B 106, 214204 (2022). We proceed to reintroduce translation invariance in the system by further ordering the disorder, and discuss the spectral structure and eigenstates features of the resulting perturbed lattices. We restore order in steps by first (i) rendering the disorder binary -- i.e. yielding a randomized checkerboard potential, then (ii) reordering the randomized checkerboard into an ordered one, and at last (iii) realigning all the checkerboard values yielding a constant potential shift, but only on a sub-lattice. Along this path, we test the influence of additional random impurities on the order restoration. We find that in each of these steps, sub-families of states are projected upon the location of the degenerate compact states, while the complementary ones are localized in the perturbed sites with energy determined by the strength of checkerboard. This strategy, herewith implemented in the 3D Lieb, highlights order restoration as experimental pathway to engineer spectral and states features in disordered lattice structures in the pursuit of quantum storage and memory applications.

description: Using three-dimensional magnetohydrodynamics simulations, we show that the efficiency of cosmic-ray (CR) production at supernova remnants (SNRs) is over-predicted if it could be estimated based on proper motion measurements of H$α$ filaments in combination with shock-jump conditions. Density fluctuations of upstream medium make shock waves rippled and oblique almost everywhere. The kinetic energy of the shock wave is transferred into that of downstream turbulence as well as thermal energy which is related to the shock velocity component normal to the shock surface. Our synthetic observation shows that the CR acceleration efficiency as estimated from a lower downstream plasma temperature, is overestimated by 10-40%, because rippled shock does not immediately dissipate all upstream kinetic energy.

description: We consider a normal lead coupled to a Majorana bound state. We show that the spin-resolved current correlations exhibit unique features which distinguish Majorana bound states from other low-energy resonances. In particular, the spin-up and spin-down currents from a Majorana bound state are anti-correlated at low bias voltages, and become uncorrelated at higher voltages. This behavior is independent of the exact form of coupling to the lead, and of the direction of the spin polarization. In contrast, an ordinary low-energy Andreev bound state gives rise to a positive correlation between the spin-up and spin-down currents, and this spin-resolved current-current correlation approaches a non-zero constant at high bias voltages. We discuss experimental setups in which this effect can be measured.

Guiding-center transformation of the radiation-reaction force in a nonuniform magnetic field

description: In this paper, we present the guiding-center transformation of the radiation-reaction force of a classical point charge traveling in a nonuniform magnetic field. The transformation is valid as long as the gyroradius of the charged particles is much smaller than the magnetic field nonuniformity length scale, so that the guiding-center Lie-transform method is applicable. Elimination of the gyromotion time scale from the radiation-reaction force is obtained with the Poisson bracket formalism originally introduced by [A. J. Brizard, Phys. Plasmas 11 4429 (2004)], where it was used to eliminate the fast gyromotion from the Fokker-Planck collision operator. The formalism presented here is applicable to the motion of charged particles in planetary magnetic fields as well as in magnetic confinement fusion plasmas, where the corresponding so-called synchrotron radiation can be detected. Applications of the guiding-center radiation-reaction force include tracing of charged particle orbits in complex magnetic fields as well as kinetic description of plasma when the loss of energy and momentum due to radiation plays an important role, e.g., for runaway electron dynamics in tokamaks.

Dismantling Delay in Care: Addressing Language Barriers at the Bedside with Communi-Cards
Creators: name: Zhang, Annie

description: Objective:  Through the implementation of Communi-Cards, this study aimed to dismantle delays in care provision for non-English-speaking patients and increase staff satisfaction by addressing language barriers at the bedside with a new, “just-in-time” interpreter tool. 
Methods: A “just-in- time” interpreter tool, Communi-Cards, was implemented in a 10-bed emergency department (ED) in a critical access hospital (CAH) in rural North Carolina. ED nursing staff completed pre and post Qualtrics surveys in response to the Communi-Cards implementation. Numerical data was drawn from multiple choice questions in pre- and post-intervention surveys, and pre- and post-intervention survey contingency tables were created from notable data sets. Open response opportunities were also offered in the pre- and post-intervention surveys. Common themes and implicative findings were explored through data analysis of pre- and post-intervention surveys.
Results: Results found that study participants of the CAH ED nursing staff were unexpectedly well connected with their interpreter resources; however, participants still indicated a need for a “just-in-time” tool that their unit did not provide. After study was completed, participants revealed varying perceptions of the Communi-Cards’ extent of effectiveness and applicability; however, participants exhibited an overall positive response in regard to the Communi-Cards resource. 
Conclusion: ED nursing staff caring for adult Spanish-speaking patients in a CAH perceived Communi-Cards as a helpful supplemental tool when in-person and digital interpreter services were unavailable or unnecessary.

Immediate applications are the evaluation of the $\overline{\rm MS}$ charm quark mass with five active flavours and the bottom quark mass at the scale of the top quark or even at GUT scales. With the help of a low-energy theorem $ζ_m$ can be used to obtain the effective coupling of a Higgs boson to light quarks with five-loop accuracy.

description: Maps have played an indispensable role in enabling safe and automated driving. Although there have been many advances on different fronts ranging from SLAM to semantics, building an actionable hierarchical semantic representation of urban dynamic scenes and processing information from multiple agents are still challenging problems. In this work, we present Collaborative URBan Scene Graphs (CURB-SG) that enable higher-order reasoning and efficient querying for many functions of automated driving. CURB-SG leverages panoptic LiDAR data from multiple agents to build large-scale maps using an effective graph-based collaborative SLAM approach that detects inter-agent loop closures. To semantically decompose the obtained 3D map, we build a lane graph from the paths of ego agents and their panoptic observations of other vehicles. Based on the connectivity of the lane graph, we segregate the environment into intersecting and non-intersecting road areas. Subsequently, we construct a multi-layered scene graph that includes lane information, the position of static landmarks and their assignment to certain map sections, other vehicles observed by the ego agents, and the pose graph from SLAM including 3D panoptic point clouds. We extensively evaluate CURB-SG in urban scenarios using a photorealistic simulator. We release our code at http://curb.cs.uni-freiburg.de.

description: The coordination-directed assembly of metal ions and organic bridging ligands has afforded a variety of bulk-scale hybrid materials with promising characteristics for a number of practical applications, such as gas storage and heterogeneous catalysis. Recently, so-called coordination polymers have emerged as a new class of hybrid nanomaterials. Herein, we highlight advances in the syntheses of both amorphous and crystalline nanoscale coordination polymers. We also illustrate how scaling down these materials to the nano-regime has enabled their use in a broad range of applications including catalysis, spin-crossover, templating, biosensing, biomedical imaging, and anticancer drug delivery. These results underscore the exciting opportunities of developing next-generation functional nanomaterials based on molecular components.

description: We investigate the role of quantum coherence in modulating the energy transfer rate between two independent energy donors and a single acceptor participating in an excitonic energy transfer process. The energy transfer rate depends explicitly on the nature of the initial coherent superposition state of the two donors and we connect it to the observed absorption profile of the acceptor and the stimulated emission profile of the energy donors. We consider simple models with mesoscopic environments interacting with the donors and the acceptor and compare the expression we obtained for the energy transfer rate with the results of numerical integration.

description: We use a geometric approach to construct a flux formulation for the SL(5) U-duality manifest exceptional field theory. The resulting formalism is well-suited for studying gauged supergravities with geometric and non-geometric fluxes. Here we describe all such fluxes for both M-theory and IIB supergravity including the Ramond-Ramond fields for compactifications to seven dimensions. We define the locally non-geometric "R-flux" and globally non-geometric "Q-flux" for M-theory and find a new locally non-geometric R-flux for the IIB theory. We show how these non-geometric fluxes can be understood geometrically and give some examples of how they fluxes can be generated by acting with dualities on solutions with geometric or field-strength flux.

description: Current state-of-the-art methods for panoptic segmentation require an immense amount of annotated training data that is both arduous and expensive to obtain posing a significant challenge for their widespread adoption. Concurrently, recent breakthroughs in visual representation learning have sparked a paradigm shift leading to the advent of large foundation models that can be trained with completely unlabeled images. In this work, we propose to leverage such task-agnostic image features to enable few-shot panoptic segmentation by presenting Segmenting Panoptic Information with Nearly 0 labels (SPINO). In detail, our method combines a DINOv2 backbone with lightweight network heads for semantic segmentation and boundary estimation. We show that our approach, albeit being trained with only ten annotated images, predicts high-quality pseudo-labels that can be used with any existing panoptic segmentation method. Notably, we demonstrate that SPINO achieves competitive results compared to fully supervised baselines while using less than 0.3% of the ground truth labels, paving the way for learning complex visual recognition tasks leveraging foundation models. To illustrate its general applicability, we further deploy SPINO on real-world robotic vision systems for both outdoor and indoor environments. To foster future research, we make the code and trained models publicly available at http://spino.cs.uni-freiburg.de.

description: We analyze how pre-existing entanglement between two Unruh-DeWitt particle detectors evolves when one of the detectors falls through a Rindler firewall in (1+1)-dimensional Minkowski space. The firewall effect is minor and does not wash out the detector-detector entanglement, in some regimes even preserving the entanglement better than Minkowski vacuum. The absence of cataclysmic events should continue to hold for young black hole firewalls. A firewall's prospective ability to resolve the information paradox must hence hinge on its detailed gravitational structure, presently poorly understood.

description: Optical imaging, which uses neither ionizing radiation (as in X-ray computed tomography) nor radioactive materials (as in positron emission tomography or single photon emission computed tomography),[1] has emerged as a powerful imaging modality during the last two decades.[2] Optical imaging has been widely employed for oncological and other applications due to its ability to noninvasively differentiate between diseased (e.g., tumor) and healthy tissues based on differential dye accumulations.[3] The need for relatively high (up to ~µM) concentrations of dyes in optical imaging, however, limits its application in many areas, such as detecting low concentrations of biological targets. For example, many biomarkers are overexpressed in the nM concentrations in diseased tissues,[4] and cannot be readily visualized by optical imaging. Dye-loaded nanoparticles represent a logical solution to lowering the detection limit due to their ability to carry a large payload of dye molecules as well as to target certain cell types by conjugation to affinity molecules. Luminescent quantum dots have indeed been extensively explored as bright and stable contrast agents for optical imaging.[5] The non-degradable nature of and the use of toxic elements in many quantum dot formulations however limit their applications in many areas. Most of fluorescent dye molecules, on the other hand, have small Stokes shifts and tend to have a significant overlap between absorption and fluorescent emission spectra. As a result, these fluorescence dyes will suffer from severe self-quenching if they are brought into close proximity with each other, as in nanoparticles with high dye loadings.

Emotional & Psychological Abuse Within the Adolescent Population
Creators: name: Tomczak, Zoë
Publisher: name: The University of North Carolina at Chapel Hill University Libraries
Year: 2023

description: Background. Adolescent dating violence (ADV) is a significant public health issue as 69% of adolescents experience abuse victimization and 63% participate in perpetration of abuse throughout their lifetime. Emotional abuse can often result in decreased self-worth, self-esteem, and one’s sense of security. Victims are often left questioning reality and second-guessing themselves and questioning reality. Recognizing stigmatization is essential as it can hinder help- seeking behaviors around partner abuse.
Purpose. The purpose of this honors project was to design and create a social media resource in the form of educational video vignettes to capture and communicate important tenets of emotional abuse in adolescents.
Methods. An analysis of the literature was conducted to evaluate the effectiveness of educational interventions in preventing adolescent dating violence (ADV). Evidence-based educational video shorts were created to convey important ADV concepts.
Results. Results from the literature analysis informed the development of educational video deliverables. Thematic analysis included: “Intervention effectiveness,” “Educational implementation recommendations,” and “Educational design and composition.” Video vignettes were created to fill practical knowledge gaps regarding emotional abuse within adolescent romantic relationships. The addition of an E-Pub format can enhance distribution of culturally appropriate when addressing values, beliefs, symbols, traditions, and history. The addition of an E-Pub format can enhance distribution. Video deliverables/vignettes were tailored to be culturally sensitive, using inclusive language to ensure relevance for people of all backgrounds, regardless of their values, beliefs, symbols, traditions, and history.
Implications. The development of educational video vignettes is an innovative approach to disseminating evidence-based messaging on emotional abuse in adolescent dating violence. The video series has great potential for educators, healthcare providers, parents, and nursing students to improve awareness and recognition of emotional abuse in adolescents. However, future research is warranted to evaluate the effectiveness of such interventions.

description: We consider a correlated Bose gas tightly confined into a ring shaped lattice, in the presence of an artificial gauge potential inducing a persistent current through it. A weak link painted on the ring acts as a source of coherent back-scattering for the propagating gas, interfering with the forward scattered current. This system defines an atomic counterpart of the rf-SQUID: the atomtronics quantum interference device (AQUID). The goal of the present study is to corroborate the emergence of an effective two-level system in such a setup and to assess its quality, in terms of its inner resolution and its separation from the rest of the many-body spectrum, across the different physical regimes. In order to achieve this aim, we examine the dependence of the qubit energy gap on the bosonic density, the interaction strength, and the barrier depth, and we show how the superposition between current states appears in the momentum distribution (time-of-flight) images. A mesoscopic ring lattice with intermediate-to-strong interactions and weak barrier depth is found to be a favorable candidate for setting up, manipulating and probing a qubit in the next generation of atomic experiments.

Assessment of Pharmacy Students’ IPEC Core Competency Using Observer-Based Evaluation in a Didactic-IPE Activity
Creators: name: Belvin, Tia
Publisher: name: The University of North Carolina at Chapel Hill University Libraries
Year: 2023

description: Introduction: Interprofessional education and practice (IPEP) experiences are important for developing
collaborative practice-ready graduates. While literature outlines various IPE activities, gaps exist
regarding IPE evaluation strategies with most published assessment tools relying on student self-evaluation. This study aimed to pilot an observer-based assessment strategy of IPEC Core Competencies
for student pharmacists participating in didactic-based IPE experiences at the UNC Eshelman School of
Pharmacy, and assess the feasibility of future implementation.
Methods: The IPEC Competency Assessment Tool of Individual Students (I-CATIS) was developed to
assess student IPEC Competency via observer-based evaluation by faculty facilitators in didactic IPE
activities. The I-CATIS was piloted in a small-group case collaboration activity involving third-year
pharmacy and dental students that evaluated thirteen IPEC sub-competencies. Pharmacy faculty
facilitators were trained on the I-CATIS and evaluated two small groups of pharmacy students. I-CATIS
results were collected and facilitators were surveyed about the I-CATIS evaluation. Students also
completed a retrospective-pre and post-self-evaluation of the IPEC competencies. I-CATIS results and
student self-evaluation scores were compared.
Results: A total of 63 pharmacy students across 12 groups were evaluated by 6 pharmacy faculty
facilitators. Facilitators indicated 71% of the IPEC sub-competency statements were Not-Observable
during the activity. Across all observed competencies, 26% of students were rated as Minimal and 64% of
students were rated as Developing the competency compared to 10% rated as Competent. Facilitators
indicated the evaluation contained valuable feedback for students but was burdensome to complete while
concurrently facilitating IPE groups in the allotted time frame.
Conclusions: The I-CATIS enabled observer-based evaluation and feedback on individual students IPEC
Competency but was challenging for pharmacy faculty to complete while simultaneously facilitating
student IPE groups. Future research will focus on utilization of non-facilitator observers, time necessary
to evaluate students, and expanding the evaluation to learners beyond the pharmacy school.

description: Catalytic direct aldol addition of α-hydroxy trialkyl phosphonacetates to aldehydes affords α-hydroxy-β-phosphonyloxy ester products. The fully substituted glycolate enolate intermediate is generated in situ under mild conditions via [1,2]-phosphonate-phosphate rearrangement. High enantioselectivity and dramatic enhancement of reaction diastereocontrol is realized via the application of chiral iminophosphorane catalysts. The phosphate products undergo stereoselective nucleophilic displacement reactions.
