Software for Training Anomalous Cognition: A Premliminary Report
The role of intuition in fields as widely divergent as science, business, and the arts has a long anecdotal history. Research into the potential for training this area of human performance, however, is not extensive. This report gives the background of anomalous cognition (AC) training devices, and describes a preliminary study involving a software program designed to enhance successful decision-making by training AC of the future and consciousness interaction with electronic systems (CIES). It was hypothesized that motivated subjects would be able to enhance their awareness of subtle internal signals or "intuitive hunches," as shown by increases in scoring. Pilot experiments by 23 experimenter/subjects yielded four who achieved significant gains in scoring at the .01 level, one who achieved both a significant increase and significant overall scoring, and two who showed significant overall scoring. Of 21 subjects who did one AC experiment, a significant percentage (71 %) showed improvement. Eight of the subjects did 25 additional AC experiments, for a total of 46 AC experiments, which together showed a significant increase in scoring, with overall chance scoring. Three subjects, including two new ones, did six CIES experiments, whose combined data showed overall significant scoring. Of 11 dropout subjects, one attained a significant increase in AC scoring. Of the total of 34 subjects, a significant number (six) achieved significant rises in scoring

Identification of 30 transition fibre proteins in Trypanosoma brucei reveals a complex and dynamic structure
Transition fibres and distal appendages surround the distal end of mature basal bodies and are essential for ciliogenesis, but only a few of the proteins involved have been identified and functionally characterised. Here, through genome-wide analysis, we have identified 30 transition fibre proteins (TFPs) and mapped their arrangement in the flagellated eukaryote Trypanosoma brucei. We discovered that TFPs are recruited to the mature basal body before and after basal body duplication, with differential expression of five TFPs observed at the assembling new flagellum compared to the existing fixed-length old flagellum. RNAi-mediated depletion of 17 TFPs revealed six TFPs that are necessary for ciliogenesis and a further three TFPs that are necessary for normal flagellum length. We identified nine TFPs that had a detectable orthologue in at least one basal body-forming eukaryotic organism outside of the kinetoplastid parasites. Our work has tripled the number of known transition fibre components, demonstrating that transition fibres are complex and dynamic in their composition throughout the cell cycle, which relates to their essential roles in ciliogenesis and flagellum length regulation
Ascertainment of Minimal Clinically Important Differences in the Diabetes Distress Scale-17: a Secondary analysis of a Randomized Clinical Trial
IMPORTANCE: The Diabetes Distress Scale-17 (DDS-17) is a common measure of diabetes distress. Despite its popularity, there are no agreed-on minimal clinically important difference (MCID) values for the DDS-17.
OBJECTIVE: to establish a distribution-based metric for MCID in the DDS-17 and its 4 subscale scores (interpersonal distress, physician distress, regimen distress, and emotional distress).
DESIGN, SETTING, AND PARTICIPANTS: This secondary analysis of a randomized clinical trial used baseline and postintervention data from a hybrid (implementation-effectiveness) trial evaluating Empowering Patients in Chronic Care (EPICC) vs an enhanced form of usual care (EUC). Participants included adults with uncontrolled type 2 diabetes (glycated hemoglobin A1c [HbA1c] level \u3e8.0%) who received primary care during the prior year in participating Department of Veterans Affairs clinics across Illinois, Indiana, and Texas. Data collection was completed in November 2018, and data analysis was completed in June 2023.
INTERVENTIONS: Participants in EPICC attended 6 group sessions led by health care professionals based on collaborative goal-setting theory. EUC included diabetes education.
MAIN OUTCOMES AND MEASURES: The main outcome was distribution-based MCID values for the total DDS-17 and 4 DDS-17 subscales, calculated using the standard error of measurement. Baseline to postintervention changes in DDS-17 and its 4 subscale scores were grouped into 3 categories: improved, no change, and worsened. Multilevel logistic and linear regression models examined associations between treatment group and MCID change categories and whether improvement in HbA1c varied in association with MCID category.
RESULTS: A total of 248 individuals with complete DDS-17 data were included (mean [SD] age, 67.4 [8.3] years; 235 [94.76%] men), with 123 participants in the EPICC group and 125 participants in the EUC group. The MCID value for DDS-17 was 0.25 and MCID values for the 4 distress subscales were 0.38 for emotional and interpersonal distress and 0.39 for physician and regimen distress. Compared with EUC, more EPICC participants were in the MCID improvement category on DDS-17 (63 participants [51.22%] vs 40 participants [32.00%]; P = .003) and fewer EPICC participants were in the worsened category (20 participants [16.26%] vs 39 participants [31.20%]; P = .008). There was no direct association of DDS-17 MCID improvement (β = -0.25; 95% CI, -0.59 to 0.10; P = .17) or worsening (β = 0.18; 95% CI, -0.22 to 0.59; P = .38) with HbA1c levels among all participants.
CONCLUSIONS AND RELEVANCE: In this secondary analysis of data from a randomized clinical trial, an MCID improvement or worsening of more than 0.25 on the DDS-17 was quantitatively significant and patients in the EPICC group were more likely to experience improvement than those in the EUC group.

Post-Dieselgate : Evidence of NOx Emission Reductions Using On-Road Remote Sensing
The Dieselgate scandal which broke in September 2015 demonstrated that vehicle manufacturers, such as the Volkswagen Group (VWG), engaged in software-based manipulation which led to vehicles passing laboratory-based emission testing limits but were far more polluting while being driven on roads. Using 23 000 on-road remote sensing measurements of light-duty Euro 5 diesel vehicles in the United Kingdom between 2012 and 2018, VWG vehicles with the "Dieselgate-affected" EA189 engine demonstrated anomalous NOx emission behavior between the pre- and post-Dieselgate periods which was not observed in other vehicle makes or models. These anomalous changes can be explained by voluntary VWG hardware and software fixes which have led to improved NOx emission control. The VGW 1.6 L vehicles, with a simple hardware fix and a software upgrade, resulted in a 36% reduction in NOx, whereas the 2.0 L vehicles that required a software-only fix showed a 30% reduction in NOx once controlled for ambient temperature effects. These results show that even minor changes or upgrades can considerably reduce NOx emissions, which has implications for future emission control activities and local air quality
Permutations whose reverse shares the same recording tableau in the RSK correspondence
The RSK correspondence is a bijection between permutations and pairs of
standard Young tableaux with identical shape, where the tableaux are commonly
denoted (insertion) and (recording). It has been an open problem to
demonstrate where is the reverse
permutation of . First we show that for each where the
recording tableau has a symmetric hook shape and satisfies a certain
simple property. From these two results, we succeed in proving the desired
identity.Comment: 14 pages, 4 figure
Reflection-impulsivity in athletes: A cross-sectional and longitudinal investigation
Reflection-impulsivity is a dimension of cognitive or decision-making style. We conducted two quasi-experimental studies to examine reflection-impulsivity in athletes using an information sampling task. In Study 1 (n = 108; Mage = 22.7 ± SDage = 1.42; 50% female), we used a cross-sectional design to compare performance across athletic expertise (super-elite, elite, amateur, novice or non-athlete) and sport type (external-paced or self-paced). In Study 2 (Time 1 n = 106; Mage = 21.32 ± SDage = 5.77; 53% female and Time 2 n = 64; Mage = 21.19 ± SDage = 5.12; 44% female), we examined changes in reflection-impulsivity across a 16-week playing season. Study 1 showed more accurate and more efficient performance as athletic expertise increased. Study 2 revealed better effectiveness and efficiency following sport participation, a 16-week playing season, most notably in elite-level performers. No sport-type differences were noted. Taken together, the studies demonstrate an association between reflection-impulsivity and athletic expertise, while also providing evidence that competitive sports participation leads to efficient decisions based on reflection, without sacrificing accuracy, which is often a consequence of impulsive decision-making
PCAT-DE: Reconstructing point-like and diffuse signals in astronomical images using spatial and spectral information
Observational data from astronomical imaging surveys contain information
about a variety of source populations and environments, and its complexity will
increase substantially as telescopes become more sensitive. Even for existing
observations, measuring the correlations between point-like and diffuse
emission can be crucial to correctly inferring the properties of any individual
component. For this task information is typically lost, either because of
conservative data cuts, aggressive filtering or incomplete treatment of
contaminated data. We present the code PCAT-DE, an extension of probabilistic
cataloging designed to simultaneously model point-like and diffuse signals.
This work incorporates both explicit spatial templates and a set of
non-parametric Fourier component templates into a forward model of astronomical
images, reducing the number of processing steps applied to the observed data.
Using synthetic Herschel-SPIRE multiband observations, we demonstrate that
point source and diffuse emission can be reliably separated and measured. We
present two applications of this model. For the first, we perform point source
detection/photometry in the presence of galactic cirrus and demonstrate that
cosmic infrared background (CIB) galaxy counts can be recovered in cases of
significant contamination. In the second we show that the spatially extended
thermal Sunyaev-Zel'dovich (tSZ) effect signal can be reliably measured even
when it is subdominant to the point-like emission from individual galaxies.Comment: 23 pages, 13 figures, Accepted for publication in The Astronomical

Control of assembly of extra-axonemal structures: The paraflagellar rod of trypanosomes
Eukaryotic flagella are complex microtubule based organelles and in many organisms there are extra axonemal structures present, including the outer dense fibres of mammalian sperm and the paraflagellar rod (PFR) of trypanosomes. Flagellum assembly is a complex process occurring across three main compartments, the cytoplasm, the transition fibre-transition zone, and the flagellum. It begins with translation of protein components, followed by their sorting and trafficking into the flagellum, transport to the assembly site and then incorporation. Flagella are formed from over 500 proteins; the principles governing axonemal component assembly are relatively clear. However, the coordination and sites of extra-axonemal structure assembly processes are less clear. We have discovered two cytoplasmic proteins in T. brucei that are required for PFR formation, PFR assembly factors 1 and 2. Deletion of either PFR-AF1 or PFR-AF2 dramatically disrupted PFR formation and caused a reduction in the amount of major PFR proteins. The presence of cytoplasmic factors required for PFR formation aligns with the concept of processes occurring across multiple compartments to facilitate axoneme assembly and this is likely a common theme for extra-axonemal structure assembly
