ROSETTA OSIRIS SHAPE MODELS OF COMET 67P/C-G
This data set collects shape models and their associated coordinate systems for the Rosetta target 67P/1969 R1 (Churyumov- Gersimenko). These were produced by the mission teams based on data obtained at the comet.
GASKELL EROS SHAPE MODEL V1.0
The shape model of 433 Eros derived by Robert Gaskell from NEAR MSI images. The model is provided in the implicitly connected quadrilateral (ICQ) format in four levels of resolution. This version of the model was prepared on Feb. 23, 2008. Vertex-facet versions of the models are also provided.
PLATE SHAPE MODEL OF COMET 103P/HARTLEY 2 V1.0
Shape model of comet 103P/Hartley 2, as derived from the Deep Impact spacecraft images obtained around the time of closest approach to the comet during the EPOXI mission. Includes maps of the surface features on the nucleus.

Highly connected 3D chromatin networks established by an oncogenic fusion protein shape tumor cell identity
<p><strong>Tumor cell identity is the product of complex interactions between oncogenic drivers and mechanisms regulating normal differentiation pathways. Cell fate transitions observed in embryonic development involve changes in 3D genomic organization that provide proper lineage specification, however, whether similar events also occur within tumor cells and contribute to cancer evolution remains largely unexplored. Here we modeled this process in the pediatric bone cancer Ewing sarcoma and investigated high resolution looping and large-scale 3D nuclear conformation changes associated with EWS-FLI1, the oncogenic fusion protein that drives this tumor. We show that chromatin interactions in Ewing sarcoma cells are dominated by highly connected looping hubs centered on EWS-FLI1 binding sites, which directly control the activity of linked enhancers and promoters to establish oncogenic expression programs. Depletion of EWS-FLI1 led to the loss of looping networks associated with the oncoprotein and, strikingly, also resulted in widespread nuclear reorganization through the establishment of new patterns of looping and large-scale inter-compartment connectivity characteristic of mesenchymal stem cells, a candidate cell of origin for this tumor. </strong><strong>Our data thus demonstrate that major architectural features of nuclear organization in cancer cells can be dependent on a single oncogenic event and readily reversed to re-establish latent differentiation programs.</strong></p>

Does chest shape influence exercise stress echocardiographic results in patients with suspected coronary artery disease?
<p>Raw data related to the article</p> <p>Abstract<br> Despite the good specificity of exercise stress echocardiography (ESE) for the detection of coronary artery disease (CAD),<br> false positive (FP) results may occur. We have previously reported that chest abnormalities may affect parameters of cardiac<br> contractility. The influence of chest shape on ESE results has never been previously investigated. We retrospectively analyzed<br> 160 consecutive patients (64.4 ± 13.0-year old, 91 women) who had undergone coronary angiography at our Institution<br> because of positive ESE, between June 2014 and May 2020. Modified Haller index (MHI; chest transverse diameter over<br> the distance between sternum and spine) was assessed in all patients. Obstructive CAD was diagnosed by ≥ 70% stenosis<br> in any epicardial coronary artery. Outcome was false-positivity at ESE. 80.6% of patients were diagnosed with obstructive<br> CAD, while 19.4% had no CAD (FP). We separately analyzed patients with normal chest shape (MHI ≤ 2.5) and those with<br> concave-shaped chest wall (MHI > 2.5). These latter were mostly women with small cardiac chambers, mitral valve prolapse<br> (MVP) and exercise-induced ST-segment changes. Likelihood of false-positivity was significantly higher in subjects with<br> MHI > 2.5 than those with MHI ≤ 2.5 (30.7% vs 9.4%, p = 0.001). By multivariate logistic regression analysis, MHI > 2.5<br> (OR 4.04, 95%CI 1.45–11.2, p = 0.007), MVP (OR 3.47, 95%CI 1.32–9–12, p = 0.01) and dyssynergy in the left circumflex<br> territory (OR = 3.35, 95%CI 1.26–8.93, p = 0.01) were independently associated with false-positivity. Concave-shaped chest<br> wall (MHI > 2.5) may be associated with false-positive stress echocardiographic result. Mechanisms underpinning this finding<br> need to be further explored.</p>

Sex-specific speed-accuracy tradeoffs shape neural processing of acoustic signals
<p>Speed-accuracy tradeoffs – being fast at the risk of being wrong – are fundamental to many decisions and natural selection is expected to resolve these tradeoffs according to the costs and benefits of behavior. We here test the prediction that females and males should integrate information from courtship signals differently because they experience different payoffs along the speed-accuracy continuum. We fitted a neural model of decision making (a drift-diffusion model of integration to threshold) to behavioral data from the grasshopper <i>Chorthippus biguttulus</i> to determine the parameters of temporal integration of acoustic directional information used by male grasshoppers to locate receptive females. The model revealed that males had a low threshold for initiating a turning response, yet a large integration time constant enabled them to continue to gather information when cues were weak. This contrasts with parameters estimated for females of the same species when evaluating potential mates, in which response thresholds were much higher and behavior was strongly influenced by unattractive stimuli. Our results reveal differences in neural integration consistent with the sex-specific costs of mate search: Males often face competition and need to be fast. Females often pay high error costs and need to be deliberate.</p>
