Collisional Fragmentation Is Not a Barrier to Close-in Planet Formation
Authors: Wallace Joshua , Tremaine Scott , Chambers John 
Published: October 2017

Abstract
Collisional fragmentation is shown to not be a barrier to rocky planet formation at small distances from the host star. Simple analytic arguments demonstrate that rocky planet formation via collisions of homogeneous gravity-dominated bodies is possible down to distances of order the Roche radius (r
Roche). Extensive N-body simulations with initial bodies ≳1700 km that include plausible models for fragmentation and merging of gravity-dominated bodies confirm this conclusion and demonstrate that rocky planet formation is possible down to ∼1.1r
Roche. At smaller distances, tidal effects cause collisions to be too fragmenting to allow mass buildup to a final, dynamically stable planetary system. We argue that even differentiated bodies can accumulate to form planets at distances that are not much larger than r
Roche.
Why do we continue using social networking sites? The giving loop that feeds computer-mediated social ties

Published: September 2017

Cet article étudie la continuité d’usage des réseaux sociaux numériques. Au travers du cadre de la théorie du don (Mauss, 1954), nous proposons une approche basée sur une boucle du don au sein des réseaux sociaux. Nous utilisons des données et techniques de recherche mixtes, avec une approche Glasérienne de la théorie enracinée. A l’aide de données qualitatives et quantitatives, nous définissons et modélisons les composantes du triptyque du don sur les réseaux sociaux ; ces composantes expliquent de manière significative la durabilité des liens sociaux médiatés. Nous mettons en évidence la relation entre les dynamiques du don réciproque et la continuité/discontinuité d’usage de Facebook. Nos résultats nous permettent de mettre en exergue l’importance de l’impact de nouvelles variables sur la continuité d’usage de Facebook. En effet, nous démontrons que la boucle du don-contre-don définie par le triptyque donner-recevoir-rendre explique la continuité d’usage du réseau social puisque les personnes qui entrent dans cette dynamique du don sont les plus enclines à utiliser le réseau social d’une manière continue.
Large Subpectoral Lipoma on Screening Mammography
Authors: Su Andres , Margolies Laurie 
Published: September 2017

A 61 year-old woman presenting for bilateral screening mammogram was found to have an oval fat-density mass in the posterior right breast, partially visualized, with anterior displacement and thinning of the pectoralis major muscle. This mass was found on CT and MRI correlation to represent a large fat-containing mass, likely a lipoma, deep to the pectoralis major. On subsequent screening mammograms, the visualized portion of the mass remained stable. Subpectoral lipomas and intramuscular lipomas within the pectoralis major are rare, and their appearance on mammography may not be familiar to most radiologists. A review of the literature and a discussion of their appearance on multiple imaging modalities is provided.
The Radiologic and Pathologic Diagnosis of Biphasic Pulmonary Blastoma
Authors: Nemeh Fadi , Kuo Anderson , Ross Jenny , Restrepo Carlos S 
Published: September 2017

Pulmonary blastomas are rare malignancies, representing 0.25% to 0.5% of all primary lung neoplasms with often aggressive progression and poor prognosis. Clinical management of pulmonary blastomas depends on histologic subtype, staging, and presentation, and may consist of surgery, chemotherapy, and radiation. Biphasic pulmonary blastoma is a subtype of pulmonary blastoma that exhibits biphasic histology, with both epithelial and mesenchymal malignant elements. We report a case of biphasic pulmonary blastoma in a 33-year-old female with 1 pack per day history of smoking for approximately 16 years, who presented with left-sided pleuritic chest pain on deep inspiration without otherwise significant pat medical history. Imaging evaluation using chest radiography, computed tomography, and magnetic resonance imaging identified a heterogenous, well-circumscribed, left lower lobe mass with extensive necrosis and hemorrhage. No lymphadenopathy or distant metastasis was detected through imaging evaluation. Surgical resection of the tumor followed by histopathological analysis confirmed a biphasic pulmonary blastoma.
Automated Detection of Conformational Epitopes Using Phage Display Peptide Sequences
Authors: Negi Surendra S , Braun Werner 
Published: October 2017

Background Precise determination of conformational epitopes of neutralizing antibodies represents a key step in the rational design of novel vaccines. A powerful experimental method to gain insights on the physical chemical nature of conformational epitopes is the selection of linear peptides that bind with high affinities to a monoclonal antibody of interest by phage display technology. However, the structural characterization of conformational epitopes from these mimotopes is not straightforward, and in the past the interpretation of peptide sequences from phage display experiments focused on linear sequence analysis to find a consensus sequence or common sequence motifs. Results We present a fully automated search method, EpiSearch that predicts the possible location of conformational epitopes on the surface of an antigen. The algorithm uses peptide sequences from phage display experiments as input, and ranks all surface exposed patches according to the frequency distribution of similar residues in the peptides and in the patch. We have tested the performance of the EpiSearch algorithm for six experimental data sets of phage display experiments, the human epidermal growth factor receptor-2 (HER-2/neu), the antibody mAb Bo2C11 targeting the C2 domain of FVIII, antibodies mAb 17b and mAb b12 of the HIV envelope protein gp120, mAb 13b5 targeting HIV-1 capsid protein and 80R of the SARS coronavirus spike protein. In all these examples the conformational epitopes as determined by the X-ray crystal structures of the antibody-antigen complexes, were found within the highest scoring patches of EpiSearch, covering in most cases more than 50% residues of experimental observed conformational epitopes. Input options of the program include mapping of a single peptide or a set of peptides on the antigen structure, and the results of the calculation can be visualized on our interactive web server.

affyPara—a Bioconductor Package for Parallelized Preprocessing Algorithms of Affymetrix Microarray Data
Authors: Schmidberger Markus , Vicedo Esmeralda , Mansmann Ulrich 
Published: October 2017

Microarray data repositories as well as large clinical applications of gene expression allow to analyse several hundreds of microarrays at one time. The preprocessing of large amounts of microarrays is still a challenge. The algorithms are limited by the available computer hardware. For example, building classification or prognostic rules from large microarray sets will be very time consuming. Here, preprocessing has to be a part of the cross-validation and resampling strategy which is necessary to estimate the rule's prediction quality honestly. This paper proposes the new Bioconductor package affyPara for parallelized preprocessing of Affymetrix microarray data. Partition of data can be applied on arrays and parallelization of algorithms is a straightforward consequence. The partition of data and distribution to several nodes solves the main memory problems and accelerates preprocessing by up to the factor 20 for 200 or more arrays. affyPara is a free and open source package, under GPL license, available form the Bioconductor project at www.bioconductor.org . A user guide and examples are provided with the package.
Hoe de criminele ladder naar de ondergang leidt

Victims of contract killing in the Amsterdam criminal scene
More than twenty criminals from Amsterdam were killed since 2012 in fierce conflicts in the criminal scene. The victims, mostly young men, can be divided into four categories. The assassins are young, often with a low intelligence, and easy to contract. They hope to give their criminal career a boost by killing. Their main motives are status and money. If the organization fears that they know too much and might inform the police, this can be a motive to kill them. Sometimes fear of betrayal of the organization is a motive for murder. The middlemen are important, because the ‘high profile targets’ want to stay out of sight of the assassins. The middlemen already have a rather secure position, although subordinate to the top. The motive to have them killed is often distrust and the fear that they know too much and would be able to tell the police too much. Revenge by another group is also an important reason they get killed. The high profile targets are top criminals in their thirties or forties mostly and in charge of the drug trafficking. The motive to have them killed is to gain influence and obtain a stronger, strategic position in the market, or – again – revenge. Rivals who are afraid to be killed, sometimes choose to be the first to act. The final category is formed by the victims killed by mistake. Recently at least three people were killed by assassins who thought they were shooting at a criminal target in the conflict. Just by mistake, because the victim drove the same kind of car, for example.
TRiC/CCT chaperonins are essential for maintaining myofibril organization, cardiac physiological rhythm, and lifespan

Published: September 2017

We recently reported that CCT chaperonin subunits are upregulated in a cardiac‐specific manner under time‐restricted feeding (TRF) [Gill S et al. (2015) Science 347, 1265–1269], suggesting that TRiC/CCT has a heart‐specific function. To understand the CCT chaperonin function in cardiomyocytes, we performed its cardiac‐specific knock‐down in the Drosophila melanogaster model. This resulted in disorganization of cardiac actin‐ and myosin‐containing myofibrils and severe physiological dysfunction, including restricted heart diameters, elevated cardiac dysrhythmia and compromised cardiac performance. We also noted that cardiac‐specific knock‐down of CCT chaperonin significantly shortens lifespans. Additionally, disruption of circadian rhythm yields further deterioration of cardiac function of hypomorphic CCT mutants. Our analysis reveals that both the orchestration of protein folding and circadian rhythms mediated by CCT chaperonin are critical for maintaining heart contractility.

Tight regulation of pH is critical for the structure and function of cells and organelles. The pH environment changes dramatically along the endocytic pathway, an internalization transport process that is ‘hijacked’ by many intracellularly active bacterial exotoxins, including the anthrax toxin. Here, we investigate the role of pH on single‐channel properties of the anthrax toxin protective antigen (PA63). Using conductance and current noise analysis, blocker binding, ion selectivity, and poly(ethylene glycol) partitioning measurements, we show that the channel exists in two different open states (‘maximum’ and ‘main’) at pH ≥ 5.5, while only a maximum conductance state is detected at pH < 5.5. We describe two substantially distinct patterns of PA63 conductance dependence on KCl concentration uncovered at pH 6.5 and 4.5.
Depth Dependence of Nearshore Currents and Eddies

Published: September 2017

AbstractThe three‐dimensional (across‐shore, alongshore, and vertical) structure of hourly mean currents and <0.01 Hz eddies was measured on a natural beach using 12 Acoustic Doppler Profilers. Both eddies and alongshore currents became relatively depth‐uniform inside the surfzone. Eddies showed greater depth dependence than alongshore currents. A two‐layer model, derived by scaling of the wave‐averaged shallow water equations, yielded separate equations for depth‐averaged and depth‐dependent velocity components. Scaling suggests, and observations confirm, only a small role for lateral advection in most surfzone cases, leading to one‐dimensional vertical models for depth dependence. For alongshore currents, depth dependence is generated by opposite forcing on lower and upper layers, respectively by bottom friction (quantified by time scale
) and waves or wind. This generation is balanced by mixing between upper and lower layers (time scale
), so the ratio between depth‐dependent and depth‐averaged alongshore currents equals
. Established models for bottom friction and breaker‐induced mixing predicted a surfzone reduction in
consistent with the observed reduction in alongshore current depth dependence. Scatter around trends was considerable. Alongshore variability was significant for depth‐dependence of currents and eddies. Inside (but not outside) the surfzone, the mixing time scale
was shorter than the eddy period, so a quasi‐steady balance was predicted between forcing and mixing of eddy depth dependence. Observed eddy depth dependence exceeded predictions for barotropic eddies generated by shear production (i.e., shear instabilities), possibly indicating generation of eddies by random breaking waves in the surfzone, or indicating baroclinic effects outside the surfzone.
