Leptonic signatures of color-sextet scalars II: Exploiting unique large-ETmissE_{\text{T}}^{\text{miss}} signals at the LHC

The diverse and distinct collider phenomenology of color-sextet scalars motivates thorough investigation of their effective couplings to the Standard Model at the LHC. Some of the more unique sextet signals involve not only jets but also leptons. In previous work, we proposed an LHC search for color-sextet scalars in a channel with jets and a hard opposite-sign lepton pair, which results from a dimension-six coupling. In this sequel we study the counterpart processes with neutrinos, which produce jets in association with missing transverse energy ($E_{\text{T}}^{\text{miss}}$) in addition to possible leptons. We consider multiple search channels, including both single and pair sextet production, all characterized by significant missing energy and some featuring distinctive kinematic features. Our multifaceted study consists of three reinterpreted existing searches and a joint-likelihood analysis designed by us to maximize HL-LHC sensitivity to single sextet production. We show that our dedicated strategy in the jets + lepton + $E_{\text{T}}^{\text{miss}}$ channel can supersede today's limits from reinterpreted searches, and we make sensitivity projections for the HL-LHC. Altogether, our analysis can exclude sextet scalars lighter than 4.4 TeV or probe effective cutoffs as high as 16.8 TeV.Comment: 16 pages, 11 figures. Updated to resemble Phys. Rev.

Drip Paintings and Fractal Analysis

It has been claimed [1-6] that fractal analysis can be applied to unambiguously characterize works of art such as the drip paintings of Jackson Pollock. This academic issue has become of more general interest following the recent discovery of a cache of disputed Pollock paintings. We definitively demonstrate here, by analyzing paintings by Pollock and others, that fractal criteria provide no information about artistic authenticity. This work has also led to two new results in fractal analysis of more general scientific significance. First, the composite of two fractals is not generally scale invariant and exhibits complex multifractal scaling in the small distance asymptotic limit. Second the statistics of box-counting and related staircases provide a new way to characterize geometry and distinguish fractals from Euclidean objects

Implementation of an Interprofessional Medication Therapy Management Experience

Objective. To measure the impact of an interprofessional experience (IPE) in medication therapy management (MTM) on students' attitudes and skills regarding interprofessional collaboration (IPC). Methods. This interprofessional MTM experience spanned three weeks, with health science students (medicine, nursing, nutrition, and pharmacy) meeting once weekly. The IPE facilitated interprofessional student collaboration via small-group sessions to conduct MTM consultations for patients with complex chronic conditions. Student learning and attitudinal changes were evaluated by comparing pre- and post-IPE survey responses and a qualitative summary of the students' clinical recommendations. Efficacy of student groups was measured via patient satisfaction surveys and was reported by frequency of response. Results. Twenty-seven students participated in the program and 22 completed both pre- and post-IPE surveys (81% response rate). The survey included open-ended and Likert-type items assessing students' attitudes and skills regarding the IPE as well as their reactions to the experience. Significant changes were observed for two attitudinal items regarding interprofessional teams: maintaining enthusiasm/interest and responsiveness to patients' emotional and financial needs. Patient-reported satisfaction and students' complex clinical recommendations provided further evidence of student learning. Conclusion. This novel IPE in MTM promoted interprofessional collaboration and education in this unique patient care area. Students' attitudes toward and skills in interprofessional collaboration improved, and the patients who received care reported positive experiences. Many health professions programs face challenges in meeting IPE requirements. The results of our study may provide the impetus for other institutions to develop similar programs to meet this urgent need.This item from the UA Faculty Publications collection is made available by the University of Arizona with support from the University of Arizona Libraries.

Exploring the impact of an Aboriginal Health Worker on hospitalised Aboriginal experiences: lessons from cardiology.

To enhance Aboriginal inpatient care and improve outpatient cardiac rehabilitation utilisation, a tertiary hospital in Western Australia recruited an Aboriginal Health Worker (AHW). Interviews were undertaken with the cardiology AHW, other hospital staff including another AHW, and recent Aboriginal cardiac patients to assess the impact of this position. The impact of the AHW included facilitating culturally appropriate care, bridging communication divides, reducing discharges against medical advice, providing cultural education, increasing inpatient contact time, improving follow-up practices and enhancing patient referral linkages. Challenges included poor job role definition, clinical restrictions and limitations in AHW training for hospital settings. This study demonstrates that AHWs can have significant impacts on Aboriginal cardiac inpatient experiences and outpatient care. Although this study was undertaken in cardiology, the lessons are transferable across the hospital setting

A community partnership to evaluate the feasibility of addressing food insecurity among adult patients in an urban healthcare system

BACKGROUND: Food insecurity (FI) is a significant public health problem. Possible sequelae of prolonged food insecurity include kidney disease, obesity, and diabetes. Our objective was to assess the feasibility of a partnership between Henry Ford Health System (HFHS) and Gleaners Community Foodbank of Southeastern Michigan to implement and evaluate a food supplementation intervention initiated in a hospital outpatient clinic setting. METHODS: We established a protocol for using the Hunger Vital Signs to screen HFHS internal medicine patients for food insecurity and established the data sharing infrastructure and agreements necessary for an HFHS-Gleaners partnership that would allow home delivery of food to consenting patients. We evaluated the food supplementation program using a quasi-experimental design and constructing a historical comparison group using the electronic medical record. Patients identified as food insecure through screening were enrolled in the program and received food supplementation twice per month for a total of 12 months, mostly by home delivery. The feasibility outcomes included successful clinic-based screening and enrollment and successful food delivery to consenting patients. Our evaluation compared healthcare utilization between the intervention and historical comparison group during a 12-month observation period using a difference-in-differences (DID) analysis. RESULTS: Of 1691 patients screened, 353 patients (20.9%) met the criteria for FI, of which 340/353 (96.3%) consented, and 256/340 (75.3%) were matched and had data sufficient for analysis. Food deliveries were successfully made to 89.9% of participant households. At follow-up, the intervention group showed greater reductions in emergency department visits than the comparison group, -41.5% and -25.3% reduction, respectively. Similar results were observed for hospitalizations, -55.9% and -17.6% reduction for intervention and control groups, respectively. DID regression analysis also showed lower trends in ED visits and hospitalizations for the intervention group compared to the comparison group. CONCLUSIONS: Results suggest that community-health system partnerships to address patient-reported food insecurity are feasible and potentially could reduce healthcare utilization in these patients. A larger, randomized trial may be the next step in fully evaluating this intervention, perhaps with more outcomes (e.g., medication adherence), and additional covariates (e.g., housing insecurity and financial strain)

Pedestrian Behavior Study to Advance Pedestrian Safety in Smart Transportation Systems Using Innovative LiDAR Sensors

Pedestrian safety is critical to improving walkability in cities. Although walking trips have increased in the last decade, pedestrian safety remains a top concern. In 2020, 6,516 pedestrians were killed in traffic crashes, representing the most deaths since 1990 (NHTSA, 2020). Approximately 15% of these occurred at signalized intersections where a variety of modes converge, leading to the increased propensity of conflicts. Current signal timing and detection technologies are heavily biased towards vehicular traffic, often leading to higher delays and insufficient walk times for pedestrians, which could result in risky behaviors such as noncompliance. Current detection systems for pedestrians at signalized intersections consist primarily of push buttons. Limitations include the inability to provide feedback to the pedestrian that they have been detected, especially with older devices, and not being able to dynamically extend the walk times if the pedestrians fail to clear the crosswalk. Smart transportation systems play a vital role in enhancing mobility and safety and provide innovative techniques to connect pedestrians, vehicles, and infrastructure. Most research on smart and connected technologies is focused on vehicles; however, there is a critical need to harness the power of these technologies to study pedestrian behavior, as pedestrians are the most vulnerable users of the transportation system. While a few studies have used location technologies to detect pedestrians, this coverage is usually small and favors people with smartphones. However, the transportation system must consider a full spectrum of pedestrians and accommodate everyone. In this research, the investigators first review the previous studies on pedestrian behavior data and sensing technologies. Then the research team developed a pedestrian behavioral data collecting system based on the emerging LiDAR sensors. The system was deployed at two signalized intersections. Two studies were conducted: (a) pedestrian behaviors study at signalized intersections, analyzing the pedestrian waiting time before crossing, generalized perception-reaction time to WALK sign and crossing speed; and (b) a novel dynamic flashing yellow arrow (D-FYA) solution to separate permissive left-turn vehicles from concurrent crossing pedestrians. The results reveal that the pedestrian behaviors may have evolved compared with the recommended behaviors in the pedestrian facility design guideline (e.g., AASHTO’s “Green Book”). The D-FYA solution was also evaluated on the cabinet-in-theloop simulation platform and the improvements were promising. The findings in this study will advance the body of knowledge on equitable traffic safety, especially for pedestrian safety in the future

A sample of 6C radio sources designed to find objects at redshift > 4: the radio data

We describe the selection of a sample of 34 radio sources from the 6C survey (Hales, Baldwin & Warner 1993) from a region of sky covering 0.133 sr. The selection criteria for this sample, hereafter called 6C*, were chosen to optimise the chances of finding radio galaxies at redshift z > 4. Optical follow-up observations have already led to the discovery of the most distant known radio galaxy at z = 4.41 (Rawlings et al. 1996). We present VLA radio maps and derive radio spectra for all the 6C* objects.Comment: 18 pages, LaTeX; also available at http://www-astro.physics.ox.ac.uk/research/preprints/ To appear in MNRA
