description: OBJECTIVE: Discussion of a case of Inclusion body myositis (IBM) associated with macroglossia.

INTRODUCTION: IBM is one of the idiopathic inflammatory myopathies. Exact pathogenesis is unclear but there is an evidence of dysregulation of antigen driven immune response involving T cells. Typical onset is slowly progressive impacting quadriceps often more than hip flexors, ankle dorsiflexors and distal forearm flexor muscles. Swallowing difficulties often are present and mild facial weakness can be seen. Macroglossia has never been reported in association with IBM. In fact inflammatory myopathies of tongue are a rarity.

DESIGN: A case report of a 68 year old woman with 12 year progressive difficulty getting out of chair and inability to twist jar lids. Examination showed forearm flexor and quadriceps atrophy and bilateral face, hip flexion and finger flexion weakness. Clinical diagnosis of IBM was further supported by muscle biopsy findings. One year after the diagnosis, she reported painless progressive enlargement of her tongue resulting in difficulty with chewing. On exam the tongue looked enlarged. MRI of the oropharynx was unremarkable. Tongue muscle biopsy showed non-granulomatous inflammatory infiltrates, myophagocytosis and degenerating regenerating fibers without evidence of amyloidosis. Work up for Sarcoidosis with Chest CT and ACE levels was negative.

RESULTS: Decision to start patient on steroids for idiopathic myositis of the tongue was deferred as our patient is currently enrolled in an IBM clinical trial.

CONCLUSION: Macroglossia in IBM patients has never been reported in literature. Two reported cases of macroglossia were associated with dermatomyositis and granulomatous myositis. It remains unknown whether this is the first reported case of IBM associated with macroglossia or macroglossia due to a second inflammatory myositis.
Closed String Partition Functions in Toroidal Compactifications of Doubled Geometries

description: We revisit partition functions of closed strings on toroidal backgrounds, including their $\mathbb{Z}_N$ shift orbifolds in the formalism where the dimension of the target space is doubled to make T-duality manifest. In such a T-duality covariant formalism, the constraint equation imposes a form of chiral factorization. Our computation furnishes a non-trivial consistency check for the quantum worldsheet theory of the doubled sigma model, when strings are placed on general toroidal backgrounds. The topological term that mixes the physical space and its T-dual is crucial in demonstrating that chiral factorization works, and that we obtain the correct partition function after imposing the constraints. Finally, we discuss how our results extend to $\mathcal{N}=1$ worldsheet supersymmetry and string worldsheets of higher genus.

title: Fetal and Childhood Effects of Children Exposed to Opioids, Opioid Maintenance Therapy (OMT), and Methamphetamine In Utero

description: The opioid use epidemic in the U.S. is a well-known growing problem. According to the U.S. Department of Health & Human Services, opioid use has increased nationally nearly 400% over the past 18 years1. Subsequently, Opioid Maintenance Therapy (OMT), methadone or buprenorphine, is expanding2. Additionally, methamphetamine (MA) use and abuse is a continuing problem worldwide. Rates of MA use are high In the U.S. and overseas rates are greater3. Opioid and MA use affects not only the user, but also friends, family, and the communities close to them4,5. A child exposed to opioids, OMT, and MA in utero may have predispositions to numerous health conditions, which is also a significant impact. After an extensive PubMed search, research appears limited on illnesses, health conditions, and ongoing health related to fetal exposure to these substances. There is a lack of sufficient study on the effects of opioid, OMT, and MA use by expectant mothers on fetal and childhood health outcomes. An exhaustive database search and a retrospective epidemiological study may provide a better understanding of the health risk of children exposed to opioids, OMT, and MA in utero.

description: In 2017, Carbapenem-resistant Enterobacteriaceae (CRE) will become a reportable infectious disease in Rhode Island. To prepare for this updated regulation, the Center for Acute Infectious Disease Epidemiology (CAIDE) analyzed Rhode Island Hospital Discharge Data (HDD), internal epidemiologic line lists, as well as antibiograms from local laboratories to gauge past incidence of CRE in Rhode Island healthcare facilities.

CAIDE used the HDD for a retrospective assessment of statewide CRE incidence in acute care hospitals from 2011-2015 using SAS 9.3 (SAS Institute, Cary, NC). Epidemiologists compiled lists of ICD-9/ICD-10 diagnosis codes that when combined indicate CRE. Codes included specific infections, antimicrobial resistance, and different specified sites (e.g. blood, urinary tract, lungs). The results of HDD inpatient population data analysis included annual counts of potential CRE diagnoses, which were used to calculate corresponding annual inpatient rates of CRE.

The results from this research inform CAIDE’s development strategy for both a statewide surveillance system and registry for CRE. Moreover, CAIDE has an enhanced understanding of annual trends to predict more accurately the potential burden of the mandatory CRE reporting on the Rhode Island Department of Health.

description: OBJECTIVE: To examine the agreement in nutrient intake and alternative healthy eating indices (AHEI) between a self-administered Food Frequency Questionnaire (FFQ) and 24-hour recall (24HR) measurements of diet by gender among older adults.

METHODS: This is a cross-sectional observational study of 105 men and 99 women aged 65 and older living in urban and rural neighborhoods in Worcester County. Participants were queried on diet using both FFQ and 24HR. The healthy eating classification was compared between the two instruments by gender.

RESULTS: For men, the mean±SD of AHEI total score was 48.2±12.3 based on FFQ versus 34.7±10.2 based on 24HR. For women, the mean±SD was 47.9±10.1 based on FFQ versus 36.1±10.0 based on 24HR. Using 32 as the cutoff (40% of maximum AHEI score), 9% of men and 7% of women were classified as eating unhealthy based on the FFQ, versus 47% of men and 38% of women based on 24HR. Compared to women, men had larger 24HR to FFQ discrepancies in the nuts and vegetable protein subscore and white/red meat ratio, and smaller discrepancy in alcohol beverages subscore.

CONCLUSION: Agreements between FFQ and 24HR-based measures of diet quality were roughly comparable between men and women, though slightly better for women than men. Compared to 24HR, the FFQ tended to underestimate the proportions of older men and women classified as eating unhealthy and misclassified more men than women. Such limitations should be considered when the FFQ is used to study healthy eating in older age.

description: We present new limits on the global shape of the dark matter halo in the Andromeda galaxy using and generalizing non-spherical mass models developed by Hayashi & Chiba and compare our results with theoretical predictions of cold dark matter (CDM) models. This is motivated by the fact that CDM models predict non-spherical virialized dark halos, which reflect the process of mass assembly in the galactic scale. Applying our models to the latest kinematic data of globular clusters and dwarf spheroidal galaxies in the Andromeda halo, we find that the most plausible cases for Andromeda yield a prolate shape for its dark halo, irrespective of assumed density profiles. We also find that this prolate dark halo in Andromeda is consistent with theoretical predictions in which the satellites are distributed anisotropically and preferentially located along major axes of their host halos. It is a reflection of the intimate connection between galactic dark matter halos and the cosmic web. Therefore, our result is profound in understanding internal dynamics of halo tracers in Andromeda, such as orbital evolutions of tidal stellar streams, which play important roles in extracting the abundance of CDM subhalos through their dynamical effects on stream structures.

description: Coronal dimming of extreme ultraviolet (EUV) emission has the potential to be a useful forecaster of coronal mass ejections (CMEs). As emitting material leaves the corona, a temporary void is left behind which can be observed in spectral images and irradiance measurements. The velocity and mass of the CMEs should impact the character of those observations. However, other physical processes can confuse the observations. We describe these processes and the expected observational signature, with special emphasis placed on the differences. We then apply this understanding to a coronal dimming event with an associated CME that occurred on 2010 August 7. Data from the Solar Dynamics Observatory's (SDO) Atmospheric Imaging Assembly (AIA) and EUV Variability Experiment (EVE) are used for observations of the dimming, while the Solar and Heliospheric Observatory's (SOHO) Large Angle and Spectrometric Coronagraph (LASCO) and the Solar Terrestrial Relations Observatory's (STEREO) COR1 and COR2 are used to obtain velocity and mass estimates for the associated CME. We develop a technique for mitigating temperature effects in coronal dimming from full-disk irradiance measurements taken by EVE. We find that for this event, nearly 100% of the dimming is due to mass loss in the corona.

We also apply this treatment to the RN-AdS black hole.

description: Despite the fact that it has been known since the time of Heisenberg that quantum operators obey a quantum version of Newton's laws, students are often told that derivations of quantum mechanics must necessarily follow from the Hamiltonian or Lagrangian formulations of mechanics. Here, we first derive the existing Heisenberg equations of motion from Newton's laws and the uncertainty principle using only the equations $F=\frac{dP}{dt}$, $P=m\frac{dV}{dt}$, and $\left[X,P\right]=i$. Then, a new expression for the propagator is derived that makes a connection between time evolution in quantum mechanics and the motion of a classical particle under Newton's laws. The propagator is solved for three cases where an exact solution is possible 1) the free particle 2) the harmonic oscillator 3) a constant force, or linear potential in the standard interpretation. Such a picture may be useful for students as they make the transition from classical to quantum mechanics and help solidify the equivalence of the Hamiltonian, Lagrangian, and Newtonian formulations of physics in their minds.

description: [abridged abstract] No, within a broad class of scenarios. With the advent of gravitational-wave (GW) astronomy, environmental effects on the GW signal will eventually have to be quantified. Here we present a wide survey of the corrections due to these effects in two situations of great interest for GW astronomy: the black hole (BH) ringdown emission and the inspiral of two compact objects. We take into account various effects such as: electric charges, magnetic fields, cosmological evolution, possible deviations from General Relativity, firewalls, and various forms of matter such as accretion disks and dark matter halos. Our analysis predicts the existence of resonances dictated by the external mass distribution, which dominate the very late-time behavior of merger/ringdown waveforms. The mode structure can drastically differ from the vacuum case, yet the BH response to external perturbations is unchanged at the time scales relevant for detectors. This is because although the vacuum Schwarzschild resonances are no longer quasinormal modes of the system, they still dominate the response at intermediate times. Our results strongly suggest that both parametrized and ringdown searches should use at least two-mode templates. Our analysis of compact binaries shows that environmental effects are typically negligible for most eLISA sources, with the exception of very few special extreme mass ratio inspirals. We show in particular that accretion and hydrodynamic drag generically dominate over self-force effects for geometrically thin disks, whereas they can be safely neglected for geometrically thick disk environments, which are the most relevant for eLISA. Finally, we discuss how our ignorance of the matter surrounding compact objects implies intrinsic limits on the ability to constrain strong-field deviations from General Relativity.

description: In cancer drug discovery, 3D cell culture is a segue between monolayer cell culture and animal testing, offering better predictive modelling of drug performance before animal testing commences. However, even though cell spheroids in 3D cultures superficially resemble tumors, they typically lack the complexity and scale of tumors formed in vivo. Spheroids typically consist of a single cell type whereas tumors contain a whole ecosystem of cells. Also, most 3D protocols stop at day 10, where the spheroids are roughly 500-600 μm in diameter at the largest, whereas tumors that develop in the body are, on average, 7.5 cm in diameter. This study investigates the effects of coculturing cell lines in 3D cultures, the effect of growth factors like Epidermal Growth Factor (EGF) on spheroids, and works on developing methods to increase the size of spheroids to more macroscopic levels. Applications for use of these 3D culture models for imaging and treatment with drug-encapsulating nanoparticles will also be presented.

description: Objective: Surrogate decision-makers (“surrogates”) and physicians of incapacitated patients have different views of prognosis and how it should be communicated, but this has not been investigated in neurocritically-ill patients. We examined communication preferences in surrogates and physician practices during the outcome prognostication for critically-ill traumatic brain injury (ciTBI) patients in neuroICUs.

Design: Qualitative study using in-person semi-structured interviews with surrogates of ciTBI patients and physicians with expertise in TBI.

Setting: Two neuroICUs at two level-1 trauma centers (surrogates); seven academic U.S. medical centers (physicians).

Subjects: Sixteen surrogates for 15 ciTBI patients and 20 attending physicians from neurocritical care, neurosurgery, trauma and palliative care.

Interventions: Not applicable.

Measurements and Main Results: We used qualitative content analysis and descriptive statistics of transcribed interviews to identify themes in surrogates and physicians. The majority of surrogates (82%) preferred numeric estimates describing the patient’s prognosis, as they felt it would limit prognostic uncertainty, which, in turn, surrogates perceived as frustrating. On the other hand, 75% of the physicians reported intentionally omitting numeric estimates during prognostication meetings due to low confidence in family members’ abilities to appropriately interpret probabilities, worry about creating false hope, and distrust in the accuracy and data quality of existing TBI outcome models. Physicians felt that TBI outcome models are for research only and should not be applied to individual patients. Surrogates valued compassion during prognostication discussions, and acceptance of their goals-of-care decision by clinicians. Physicians and surrogates agreed on avoiding false hope.

Conclusions: We identified fundamental differences in preferences for the communication of prognostic information between surrogates of ciTBI patients and physicians during goals-of-care discussions. A decision aid could potentially bridge this chasm by providing surrogates consistent and patient-centered information, however, with qualitative rather than quantitative estimates of ciTBI prognosis and an open disclosure of uncertainty.

description: Objectives: Parkinson’s Disease (PD), Dementia with Lewy bodies (DLB), and Multiple System Atrophy (MSA) are neurodegenerative disorders of the aging population characterized by the progressive accumulation of alpha-synuclein. Jointly these disorders have been denominated synucleinopathies and currently no disease modifying treatments are available. Previous in vivo studies in transgenic (tg) mice have shown that active and passive immunization targeting alpha-synuclein ameliorates to some extent deficits and synuclein accumulation, however it’s unknown if combining humoral and cellular immunization might synergize and also reduce inflammation and improve microglial cell mediated synuclein clearance.

Methods: PDGF- alpha-synuclein tg mice and control non-tg mice were immunized with: 1) Glucan Particle (GP) adjuvant alone, 2) GP human (hu)- alpha-synuclein (active immunization), 3) GP plus rapamycin and 4) GP plus rapamycin and hu-alpha-synuclein (combined active and humoral) and analyzed by neuropathological and biochemical markers.

Results: Compared to tg mice treated with adjuvant alone, mice immunized with GP hu-alpha-synuclein displayed a 30% reduction in alpha-synuclein accumulation. Combined immunotherapy with GP plus rapamycin and hu-alpha-synuclein resulted in 50% reduction in alpha-synuclein accumulation which was accompanied by reduced neuro-inflammation (Iba-1, GFAP, IL6, TNFalpha), phospho and insoluble alpha-synuclein, microglia and astroglia cell numbers, and retention of CD25, FoxP3 and CD4 positive cells. Levels of TGFb1 were also increased. Serological studies showed that active immunization resulted in higher levels of total IgG, IgG1 and IgG2 titers, levels were slightly higher in the combined group.

Conclusions: In vivo studies targeting alpha-synuclein support the hypothesis that cellular immunization might enhance the effects of active immunotherapy for the treatment of synucleionopathies.

description: We study gravity with torsion in extra dimensions and derive an effective four-dimensional theory containing four-fermion contact operators at the fundamental scale of quantum gravity in the TeV range. These operators may have an impact on the low-energy observables and can manifest themselves or can be constrained in precision measurements. We calculate possible contributions of these operators to some observables at the one-loop level. We show that the existing precision data on the lepton decay mode of Z boson set limits on the fundamental scale of the gravity and compactification radius, which are more stringent than the limits previously derived in the literature.

description: Analysing historical patterns of artificial intelligence (AI) adoption can inform decisions about AI capability uplift, but research to date has provided a limited view of AI adoption across various fields of research. In this study we examine worldwide adoption of AI technology within 333 fields of research during 1960-2021. We do this by using bibliometric analysis with 137 million peer-reviewed publications captured in The Lens database. We define AI using a list of 214 phrases developed by expert working groups at the Organisation for Economic Cooperation and Development (OECD). We found that 3.1 million of the 137 million peer-reviewed research publications during the entire period were AI-related, with a surge in AI adoption across practically all research fields (physical science, natural science, life science, social science and the arts and humanities) in recent years. The diffusion of AI beyond computer science was early, rapid and widespread. In 1960 14% of 333 research fields were related to AI (many in computer science), but this increased to cover over half of all research fields by 1972, over 80% by 1986 and over 98% in current times. We note AI has experienced boom-bust cycles historically: the AI "springs" and "winters". We conclude that the context of the current surge appears different, and that interdisciplinary AI application is likely to be sustained.

description: We show that the Drinfel'd double associated to the standard quantum deformation $sl_η(2,R)$ is isomorphic to the (2+1)-dimensional AdS algebra with the initial deformation parameter $η$ related to the cosmological constant $Λ=-η^2$. This gives rise to a generalisation of a non-commutative Minkowski spacetime that arises as a consequence of the quantum double symmetry of (2+1) gravity to non-vanishing cosmological constant. The properties of the AdS quantum double that generalises this symmetry to the case $Λ\neq 0$ are sketched, and it is shown that the new non-commutative AdS spacetime is a nonlinear $Λ$-deformation of the Minkowskian one.

description: PURPOSE: Hip fracture is an increasingly common cause of morbidity and mortality in the aging U.S. population. Multiple studies have shown that patients who undergo surgical repair within 48 hours of the initial injury have better outcomes. The use of a perioperative care pathway (PCP) for hip fracture patients combines prompt surgical repair with dedicated medical services tailored to patients’ specific comorbidities.

METHODS: Our level 1 trauma center implemented a PCP in October 2015, requiring only anesthesia (not hospital medicine) clearance prior to surgery. We identified all hip fracture patients who presented to our level 1 hospital for one year prior to, and one year following, implementation of the pathway. We then performed a comprehensive clinical chart review to collect demographic data, past medical history, and perioperative factors. We performed statistical analyses to evaluate whether using the pathway improved patient outcomes.

RESULTS: Preliminary analyses were performed on a series of patients pre- (n=96) and post-pathway (n=100). We summarized patient characteristics and reported these according to participation in the pathway. Distributions were evaluated for normality and to evaluate for outliers. Proportions were reported for categorical variables and assessed for differences using the chi-square test, and continuous data were summarized by means and standard deviations and assessed for differences using the t-test. We found that patients in the pathway worked with physical therapy (PT) an average of 16.8 hours earlier (p=0.013).

CONCLUSION: The use of PCPs represents an emerging approach to hip fracture management, but a widely generalizable PCP has yet to be definitively described. Our patients’ decrease in time to PT may be attributable to better postoperative optimization by hospitalist medicine. We anticipate that multivariate analyses will reveal additional gains. Ultimately, our experience may yield implications for the safe, cost- and time-effective surgical care of hip fracture patients nationally.

description: INTRODUCTION: Liposomal bupivacaine (LB) is a slowly degrading preparation that provides local anesthesia for up to 72 hours. It targets the site directly responsible for pain sensation, with no associated motor blockade. In total knee arthroplasty (TKA), it may have superior outcomes to anesthesia with regional nerve block.

METHODS: Our surgeons began using LB in TKA patients in 2013. All patients following each surgeon’s LB start date were the experimental group. An equivalent number of patients prior to 2013 served as the control group. All control group patients received a preoperative femoral nerve block, and all experimental group patients received peri- and intra-articular LB, delivered intraoperatively. All other surgical and anesthesia interventions were the same. We used retrospective chart review to identify patient demographics, time to first ambulation, time to discharge, and incidence of postoperative nausea and vomiting. We also recorded opioid consumption intraoperatively, in the recovery room, and on the floor.

RESULTS: There were 161 patients in each group. We found no significant difference between the two groups with regard to gender, age, weight, preoperative opioid exposure, side of procedure, type of anesthesia (general vs. spinal), or ASA status. On average, LB patients consumed 29.2% less opioid after leaving the recovery room (p

DISCUSSION AND CONCLUSION: With increasing focus on the cost of TKA, there is strong incentive to manage costs associated with the procedure. Additionally, all patients, regardless of comorbid conditions, can benefit from limited exposure to narcotic pain medication. Our results indicate that LB decreases total systemic opioid requirement, time to first ambulation, and time to discharge from the hospital.

description: BICEP2 has reported the detection of a degree-scale B-mode polarization pattern in the Cosmic Microwave Background (CMB) and has interpreted the measurement as evidence for primordial gravitational waves. Motivated by the profound importance of the discovery of gravitational waves from the early Universe, we examine to what extent a combination of Galactic foregrounds and lensed E-modes could be responsible for the signal. We reanalyze the BICEP2 results and show that the 100x150 GHz and 150x150 GHz data are consistent with a cosmology with r=0.2 and negligible foregrounds, but also with a cosmology with r=0 and a significant dust polarization signal. We give independent estimates of the dust polarization signal in the BICEP2 region using four different approaches. While these approaches are consistent with each other, the expected amplitude of the dust polarization power spectrum remains uncertain by about a factor of three. The lower end of the prediction leaves room for a primordial contribution, but at the higher end the dust in combination with the standard CMB lensing signal could account for the BICEP2 observations, without requiring the existence of primordial gravitational waves. By measuring the cross-correlations between the pre-Planck templates used in the BICEP2 analysis and between different versions of a data-based template, we emphasize that cross-correlations between models are very sensitive to noise in the polarization angles and that measured cross-correlations are likely underestimates of the contribution of foregrounds to the map. These results suggest that BICEP1 and BICEP2 data alone cannot distinguish between foregrounds and a primordial gravitational wave signal, and that future Keck Array observations at 100 GHz and Planck observations at higher frequencies will be crucial to determine whether the signal is of primordial origin.

description: Background: Although prior studies have linked troponin I (TnI) elevation, serum sodium (Na) fluctuation, and reduced ejection fraction (EF) with an increased mortality in the medical/surgical critical care units, this has not been validated in the CCU. We aim to identify clinical and laboratory factors to predict cardiac related length of survival (LOS) in the CCU.

Methods: We retrospectively analyzed 134 consecutive patients who were admitted to the CCU from December 2012 to March 2015, and who died during that admission. We used student T-test, correlation matrices, and Framingham risk factors adjusted multivariable logistic regression models to examine the role of TnI, serum Na, EF and other clinical covariates on LOS in cardiac death (CD) and non- cardiac death (NCD) group.

Results: The average age of the study population was 70.0 ±14.3 (39.0% women). The prevalence of CD and NCD were 63% and 59%. LOS was statistically shorter in the CD vs. NCD group (5.3 days vs. 8.2 days, p=0.012). LOS negatively correlated with initial TnI (p= 0.05). LOS was not statistically affected by EF or Na level. Our regression models identified BMI and diabetes mellitus (DM) as strong predictors of CD (p= 0.04 and p=0.01).

Conclusion: Our results validate prior studies showing that TnI, BMI, and DM are predictors of cardiac related mortality in the CCU. Patients with a cardiac etiology had a higher mortality rate and a shorter LOS. Future studies are needed to develop a scoring system specific for predicting mortality in the CCU.

description: Aim: To assess the efficacy of a newly implemented resident simulation curriculum at a medium sized pediatric residency program.

Background: Many pediatric residency programs incorporate high-fidelity simulation into their curriculum, but there is limited data discussing the utility/educational impacts of a longitudinal/standardized/multimodal simulation curriculum. Several studies of simulation-based training have employed “self-efficacy” as a barometer for trainee education and performance 1,2,. The level of a person’s self-efficacy can influence their behavior and may be a pivotal factor in performance. We have implemented a newly devised standardized, multimodal resident simulation curriculum and used resident self-efficacy to assess its effectiveness.

Methods: Participants were UMass Pediatric and Med/Peds residents. Implementation of our curriculum occurred at the start of the 2016-2017 academic year. Surveys were administered to all residents prior to curriculum implementation and at 6 months post-implementation. They assessed resident self-efficacy with regards to specific technical/procedural skills (i.e. running a code, performing intubation, etc.) and resident confidence in their ability to identify/manage specific pediatric disease presentations (i.e. respiratory failure, tachyarrhythmia, etc.). Data was pooled and averaged for each resident class separately. We predetermined a 10% change in self-efficacy to be a clinically significant difference.

Results: 36 of 40 residents completed the initial survey and 31 completed the 6-month follow-up. PGY1 residents reported improved self-efficacy for 4 PALS-related skills and 8 pediatric case presentations. Similarly, PGY2 residents reported improved self-efficacy for 3 PALS-related skills and 6 pediatric case presentations. Conversely, PGY3/4 residents reported no significant change in self-efficacy for any survey question.

Conclusions: These results suggest that our newly implemented longitudinal, standardized, multidisciplinary, multi-modal simulation curriculum has significantly improved resident self-efficacy related to core Pediatric Advanced Life-Support (PALS) skills/topics, with the greatest impact affecting our PGY1 class. Further study and curriculum development will attempt to address this issue.

description: We derive a general criterion that defines all single-field models leading to Starobinsky-like inflation and to universal predictions for the spectral index and tensor-to-scalar ratio, which are in agreement with Planck data. Out of all the theories that satisfy this criterion, we single out a special class of models with the interesting property of retaining perturbative unitarity up to the Planck scale. These models are based on induced gravity, with the Planck mass determined by the vacuum expectation value of the inflaton.

title: Development and Evaluation of a Mentorship to Hire Program for Facilitating Nursing Role Development and Transition to Practice
Creators: name: Schuler, Monika S.
Publisher: name: eScholarship@UMMS
Year: 2017

description: The purpose of this poster is to present an ongoing community engaged research (CER) initiative at the University of Massachusetts Dartmouth College of Nursing (CON) examining in what ways a mentorship to hire (MTH) program with community partners may facilitate role development and transition to practice for senior nursing students and retention in health care organizations upon graduation.

New nursing graduates have a difficult time transitioning to practice in part because of unrealistic perceptions about the nursing role. Difficult transitions can be costly to health care organizations (HCO) who often invest time and money in new graduate hires only for them to leave the practice setting after a short period of time. An additional concern is a current and anticipated shortage of nurses in specialty areas such as post-operative, emergency, and psychiatric nursing. As part of the CON curriculum, senior nursing students must complete 120 hours of mentorship in a health care organization during the last semester of their program where students are paired with a professional registered nurse in a one-on-one concentrated practicum. This practicum provides students with clinical experiences and facilitates transitions to practice, however, HCOs often have a limited number of nurses available for precepting our students in part because of an increased demand and competition between nursing schools for clinical placements.

In an effort to find a mutually beneficial solution, a mentorship to hire program was proposed and developed between two health care organizations and the CON. This poster will discuss the development of the CER program and plans for assessing transition to practice, perceptions of readiness for practice, role development, and retention of the new graduates upon completion of the program. Furthermore plans for evaluating health care organization perceptions including evaluation of fit for organizations, costs associated with training, and retention will also be presented.

description: A basic principle of long baseline interferometry is that an optical path difference (OPD) directly translates into an astrometric measurement. In the simplest case, the OPD is equal to the scalar product between the vector linking the two telescopes and the normalized vector pointing toward the star. However, a too simple interpretation of this scalar product leads to seemingly conflicting results, called here "the baseline paradox". For micro-arcsecond accuracy astrometry, we have to model in full the metrology measurement. It involves a complex system subject to many optical effects: from pure baseline errors to static, quasi-static and high order optical aberrations. The goal of this paper is to present the strategy used by the "General Relativity Analysis via VLT InTerferometrY" instrument (GRAVITY) to minimize the biases introduced by these defects. It is possible to give an analytical formula on how the baselines and tip-tilt errors affect the astrometric measurement. This formula depends on the limit-points of three type of baselines: the wide-angle baseline, the narrow-angle baseline, and the imaging baseline. We also, numerically, include non-common path higher-order aberrations, whose amplitude were measured during technical time at the Very Large Telescope Interferometer. We end by simulating the influence of high-order common-path aberrations due to atmospheric residuals calculated from a Monte-Carlo simulation tool for Adaptive optics systems. The result of this work is an error budget of the biases caused by the multiple optical imperfections, including optical dispersion. We show that the beam stabilization through both focal and pupil tracking is crucial to the GRAVITY system. Assuming the instrument pupil is stabilized at a 4 cm level on M1, and a field tracking below 0.2$λ/D$, we show that GRAVITY will be able to reach its objective of 10$μ$as accuracy.
