Objective:
Risk factors that contribute to brain pathology and cognitive decline among older adults include demographic factors (e.g., age, educational attainment), genetic factors, health factors, and depression (Plassman et al., 2010). Variability within an individual’s performance across cognitive tasks is referred to as dispersion (Hultsch et al., 2002), which appears sensitive to subtle cognitive impairments associated with neurodegenerative pathology in older adults (Bangen et al., 2019; Kälin et al., 2014). Thaler and colleagues (2015) found that dispersion across domains of the Repeatable Battery for the Assessment of Neuropsychological Status (RBANS) was a useful indicator of cognitive changes associated with cardiovascular disease and mortality. Also, research by Manning and colleagues (2021) found that elevated ratings of depression and anxiety in older adults was associated with greater dispersion across neuropsychological testing. The present study aimed to replicate findings that greater dispersion in neuropsychological performance is associated with impaired neurocognitive performance and greater self-reported depression among older adults who present for neuropsychological evaluation with cognitive concerns.
Participants and Methods:Neuropsychological testing data was obtained from a university hospital. Chart reviews were conducted on 369 participants who met initial criteria (60 years or older with testing data from the RBANS Form A, Wechsler Test of Adult Reading, and Geriatric Depression Scale [GDS]). Retrospective analyses were conducted on a final sample of 293 participants from 60 to 94 years old (Mage = 74.41, SDage = 7.43; 179 females, 114 males). Diagnoses were used for group comparisons between cognitively intact individuals with subjective cognitive complaints (SCC, n = 49), persons with Mild Neurocognitive Disorder (mND, n =137), and persons with Major Neurocognitive Disorder (MND, n = 107).
Results:As expected, results indicated that higher dispersion was related to lower Total RBANS Scores (r = -0.54, p < .001) and significant differences across diagnostic groupings (F(2, 289) = 29.19, p < 0.001; SCC, mND, MND) indicated that variability in performance was an indicator of greater neurocognitive impairment. Contrary to expectations, greater dispersion was very weakly associated with lower reported depressive symptomatology (r = -0.13, p = 0.03). A three-stage hierarchical linear regression was conducted with the RBANS Coefficient of Variation (CoV) as the dependent variable and three predictor variables (Age, Total RBANS, Total GDS). The regression analysis results indicated that age was not a significant predictor, but both Total RBANS and GDS Scores were. The most important predictor was Total RBANS Scores which uniquely explained 21% of the variation in dispersion.
Conclusions:This study adds to the current literature regarding the clinical utility of dispersion in neuropsychological performance as an indicator of early and subtle neurocognitive impairment. Depressive symptom reporting was expected to help predict the degree of variability, but this factor was only weakly associated with the RBANS CoV.
Limitations of this study include its retrospective use of archival data and the restricted range on some variables of interest. Further research is needed to examine the relative utility of different measures of dispersion and why increased cognitive performance variability is related to neurocognitive impairment and decline.

Objective:
Individuals with attention-deficit/hyperactivity disorder (ADHD) exhibit deficits in reward-based learning, which have important implications for behavioral regulation. Prior research has shown that these individuals show altered patterns of risky decision-making, which may be partially explained as a function of dysfunctional reactivity to rewards and punishments. However, research findings on the relationships between ADHD and punishment sensitivity have been mixed. The current study used the Balloon Analog Risk Task (BART) to examine risky decision-making in adults with and without ADHD, with a particular interest in characterizing the manner in which participants react to loss.
Participants and Methods:612 individuals (Mage = 31.04, SDage = 78.77; 329 females, 283 males) were recruited through the UCLA Consortium for Neuropsychiatric Phenomics (CNP). All participants were administered the Structured Clinical Interview for DSM-IV-TR (SCID-IV), which provided diagnoses used for group comparisons between adults with ADHD (n = 35) and healthy controls (n = 577). A computerized BART paradigm was used to examine impulsivity and risky decision-making, while participants also completed the Barratt Impulsiveness Scale (BIS-11), and ADHD participants completed the Adult Self-Report Scale-V1.1 (ASRS-V1.1). The BART presented two colors of balloons with differing probabilities of exploding, and participants were incentivized to pump the balloons as many times as possible without causing them to explode. The primary endpoint was "mean adjusted pumps", determined as mean across trials of the number of pumps on trials that did not end in explosion. An index of reactivity to loss was calculated as the difference between the mean adjusted pumps following an explosion and the mean adjusted pumps following trials in which the balloon did not explode.
Results:The ADHD and control groups did not differ on mean adjusted pumps across trials, but they did differ in their reactivity to explosion of balloons that followed the most pumps, incurring the greatest level of loss (F(1, 551) = 7.1, p < 0.01). Interestingly, ADHD participants showed a greater reactivity to loss on these balloons than controls (p < 0.05), indicating that they reduced their number of pumps following balloon explosions more than controls. For participants as a whole, there were small correlations between loss reactivity and scales of everyday impulsivity on the BIS-II (ps < 0.05). For ADHD participants, loss reactivity was unrelated to symptoms of inattention but was significantly correlated with symptoms of hyperactivity/impulsivity (p = 0.01) and total ADHD symptoms (p < 0.05) on the ASRS-V1.1.
Conclusions:In the context of a risky decision-making task, adults with ADHD showed greater reactivity to loss than controls, despite showing comparable patterns of overall performance during the BART. The magnitude of behavioral adjustment following loss was correlated with symptoms of hyperactivity/impulsivity in adults with ADHD, suggesting that loss sensitivity is clinically related to impulsive behavior in everyday life. These findings help to expand our understanding of motivational processing in ADHD and suggest new insight into the ways in which everyday symptoms of ADHD are related to sensitivity to losses and punishments.

Background:
The transition from residency to paediatric cardiology fellowship is challenging due to the new knowledge and technical skills required. Online learning can be an effective didactic modality that can be widely accessed by trainees. We sought to evaluate the effectiveness of a paediatric cardiology Fellowship Online Preparatory Course prior to the start of fellowship.
Methods:The Online Preparatory Course contained 18 online learning modules covering basic concepts in anatomy, auscultation, echocardiography, catheterisation, cardiovascular intensive care, electrophysiology, pulmonary hypertension, heart failure, and cardiac surgery. Each online learning module included an instructional video with pre-and post-video tests. Participants completed pre- and post-Online Preparatory Course knowledge-based exams and surveys. Pre- and post-Online Preparatory Course survey and knowledge-based examination results were compared via Wilcoxon sign and paired t-tests.
Results:151 incoming paediatric cardiology fellows from programmes across the USA participated in the 3 months prior to starting fellowship training between 2017 and 2019. There was significant improvement between pre- and post-video test scores for all 18 online learning modules. There was also significant improvement between pre- and post-Online Preparatory Course exam scores (PRE 43.6 ± 11% versus POST 60.3 ± 10%, p < 0.001). Comparing pre- and post-Online Preparatory Course surveys, there was a statistically significant improvement in the participants’ comfort level in 35 of 36 (97%) assessment areas. Nearly all participants (98%) agreed or strongly agreed that the Online Preparatory Course was a valuable learning experience and helped alleviate some anxieties (77% agreed or strongly agreed) related to starting fellowship.
Conclusion:An Online Preparatory Course prior to starting fellowship can provide a foundation of knowledge, decrease anxiety, and serve as an effective educational springboard for paediatric cardiology fellows.

This paper describes a computational investigation of multimode instability growth and multimaterial mixing induced by multiple shock waves in a high-energy-density (HED) environment, where pressures exceed 1 Mbar. The simulations are based on a series of experiments performed at the National Ignition Facility (NIF) and designed as an HED analogue of non-HED shock-tube studies of the Richtmyer–Meshkov instability and turbulent mixing. A three-dimensional computational modelling framework is presented. It treats many complications absent from canonical non-HED shock-tube flows, including distinct ion and free-electron internal energies, non-ideal equations of state, radiation transport and plasma-state mass diffusivities, viscosities and thermal conductivities. The simulations are tuned to the available NIF data, and traditional statistical quantities of turbulence are analysed. Integrated measures of turbulent kinetic energy and enstrophy both increase by over an order of magnitude due to reshock. Large contributions to enstrophy production during reshock are seen from both the baroclinic source and enstrophy–dilatation terms, highlighting the significance of fluid compressibility in the HED regime. Dimensional analysis reveals that Reynolds numbers and diffusive Péclet numbers in the HED flow are similar to those in a canonical non-HED analogue, but conductive Péclet numbers are much smaller in the HED flow due to efficient thermal conduction by free electrons. It is shown that the mechanism of electron thermal conduction significantly softens local spanwise gradients of both temperature and density, which causes a minor but non-negligible decrease in enstrophy production and small-scale mixing relative to a flow without this mechanism.

The environmental impact resulting from the use of fossil fuel as an energy source affects the entire globe. Eventually, fossil fuels will no longer be a reasonable source of energy and alternative energy sources will be needed. Thermoelectric materials (TE) that directly convert heat into electricity are a viable option to replace the conventional fossil fuel because they are reliable, cost effective, and use no moving parts. Recently researchers discovered the existence of giant Seebeck coefficient in manganese oxide (MnO2) powders, which ignited an increased interest in MnO2-based materials. In this work we present a systematic structural and electrical characterization of amorphous and crystalline MnxOy thin films. These films were deposited at room temperature on heated silicon and sapphire substrates by DC Magnetron Sputtering. Our preliminary results show that MnxOy/silicon thin films undergo a crystalline change from Mn2O3 to Mn3O4 as annealing temperature is increased from 300°C to 500°C.

It is important to evaluate use of urban-proximate outdoor recreation sites by diverse groups and obtain visitor viewpoints about those sites. Of particular importance are day-use sites, which receive a large amount of use but little research emphasis. Managers of urban-proximate day-use sites can better manage with detailed specific information about participation patterns, site preferences, and visitor perceptions. Results are offered from visitor contact surveys conducted at day-use sites on four urban national forests in Southern California between 2001 and 2004, with a focus on areas where Latinos recreate. These data indicate many similarities among the Latino visitors to specific sites in four Southern California forests. There were commonalities in participation in outdoor recreation activities, the relative importance of site attributes, and perceptions reported about their recreation experiences. The results suggest that management decisions about serving these groups consider the range of activity options identified, that there is a consistent desire for facilities and amenities, and that the Latino visitors are likely to continue to recreate in these places and will tell others about it, probably leading to increased use by these respondent groups in the future.

In spite of concerns, Minnesota‘s dominant cropping system is the corn–soybean rotation using synthetic pesticides and chemically processed fertilizers. Using experimental data from 1990–99, this study compared the profitability of organic versus conventional strategies. Net return (NR) was calculated from actual yields, operations, inputs, prices and organic premiums. Yields and costs were lower for the 4-year organic strategy. With premiums, the 4-year organic strategy had NRs significantly higher than conventional strategies; without premiums, the NRs were statistically equal (P = 0.05). Thus, the 4-year organic strategy was not less profitable nor its NR more variable than the conventional strategies in this study.

The first dedicated local electrode atom probes (LEAP [a trademark of Imago Scientific Instruments Corporation]) have been built and tested as commercial prototypes. Several key performance parameters have been markedly improved relative to conventional three-dimensional atom probe (3DAP) designs. The Imago LEAP can operate at a sustained data collection rate of 1 million atoms/minute. This is some 600 times faster than the next fastest atom probe and large images can be collected in less than 1 h that otherwise would take many days. The field of view of the Imago LEAP is about 40 times larger than conventional 3DAPs. This makes it possible to analyze regions that are about 100 nm diameter by 100 nm deep containing on the order of 50 to 100 million atoms with this instrument. Several example applications that illustrate the advantages of the LEAP for materials analysis are presented.
