--- _id: '12600' abstract: - lang: eng text: The snow cover dynamics of High Mountain Asia are usually assessed at spatial resolutions of 250 m or greater, but this scale is too coarse to clearly represent the rugged topography common to the region. Higher-resolution measurement of snow-covered area often results in biased sampling due to cloud cover and deep shadows. We therefore develop a Normalized Difference Snow Index-based workflow to delineate snow lines from Landsat Thematic Mapper/Enhanced Thematic Mapper+ imagery and apply it to the upper Langtang Valley in Nepal, processing 194 scenes spanning 1999 to 2013. For each scene, we determine the spatial distribution of snow line altitudes (SLAs) with respect to aspect and across six subcatchments. Our results show that the mean SLA exhibits distinct seasonal behavior based on aspect and subcatchment position. We find that SLA dynamics respond to spatial and seasonal trade-offs in precipitation, temperature, and solar radiation, which act as primary controls. We identify two SLA spatial gradients, which we attribute to the effect of spatially variable precipitation. Our results also reveal that aspect-related SLA differences vary seasonally and are influenced by solar radiation. In terms of seasonal dominant controls, we demonstrate that the snow line is controlled by snow precipitation in winter, melt in premonsoon, a combination of both in postmonsoon, and temperature in monsoon, explaining to a large extent the spatial and seasonal variability of the SLA in the upper Langtang Valley. We conclude that while SLA and snow-covered area are complementary metrics, the SLA has a strong potential for understanding local-scale snow cover dynamics and their controlling mechanisms. article_processing_charge: No article_type: original author: - first_name: Marc full_name: Girona‐Mata, Marc last_name: Girona‐Mata - first_name: Evan S. full_name: Miles, Evan S. last_name: Miles - first_name: Silvan full_name: Ragettli, Silvan last_name: Ragettli - first_name: Francesca full_name: Pellicciotti, Francesca id: b28f055a-81ea-11ed-b70c-a9fe7f7b0e70 last_name: Pellicciotti citation: ama: Girona‐Mata M, Miles ES, Ragettli S, Pellicciotti F.

However, very few studies have looked at these features on the catchment scale to determine their patterns and changes in space and time. We have compiled a detailed inventory of cliffs and ponds in the Langtang catchment, central Himalaya, from six high-resolution satellite orthoimages and DEMs between 2006 and 2015, and a historic orthophoto from 1974. Cliffs cover between 1.4% (± 0.4%) in the dry and 3.4% (± 0.9%) in the wet seasons and ponds between 0.6% (± 0.1%) and 1.6% (± 0.3%) of the total debris-covered tongues. We find large variations between seasons, as cliffs and ponds tend to grow in the wetter monsoon period, but there is no obvious trend in total area over the study period. The inventory further shows that cliffs are predominately north-facing irrespective of the glacier flow direction. Both cliffs and ponds appear in higher densities several hundred metres from the terminus in areas where tributaries reach the main glacier tongue. On the largest glacier in the catchment ~10% of all cliffs and ponds persisted over nearly a decade. article_processing_charge: No article_type: original author: - first_name: JAKOB F. full_name: STEINER, JAKOB F. last_name: STEINER - first_name: PASCAL full_name: BURI, PASCAL last_name: BURI - first_name: EVAN S. full_name: MILES, EVAN S. last_name: MILES - first_name: SILVAN full_name: RAGETTLI, SILVAN last_name: RAGETTLI - first_name: Francesca full_name: Pellicciotti, Francesca id: b28f055a-81ea-11ed-b70c-a9fe7f7b0e70 last_name: Pellicciotti citation: ama: 'STEINER JF, BURI P, MILES ES, RAGETTLI S, Pellicciotti F.

We focus on two glaciers with contrasting surface characteristics: a debris-covered glacier (Langtang Glacier in Nepal) and a clean-ice glacier (Hintereisferner in Austria). The model is applied from the end of the Little Ice Age (1850) to the present-day (2016) and is forced with four bias-corrected General Circulation Models (GCMs) from the historical experiment of the CMIP5 archive. The selected GCMs represent region-specific warm-dry, warm-wet, cold-dry, and cold-wet climate conditions. To isolate the effects of anthropogenic climate change on glacier mass balance and flow runs from these GCMs with and without further anthropogenic forcing after 1970 until 2016 are selected. The outcomes indicate that both glaciers experience the largest reduction in area and volume under warm climate conditions, whereas area and volume reductions are smaller under cold climate conditions. Simultaneously with changes in glacier area and volume, surface velocities generally decrease over time. Without further anthropogenic forcing the results reveal a 3% (9%) smaller decline in glacier area (volume) for the debris-covered glacier and a 18% (39%) smaller decline in glacier area (volume) for the clean-ice glacier. The difference in the magnitude between the two glaciers can mainly be attributed to differences in the response time of the glaciers, where the clean-ice glacier shows a much faster response to climate change. We conclude that the response of the two glaciers can mainly be attributed to anthropogenic climate change and that the impact is larger on the clean-ice glacier. The outcomes show that the model performs well under different climate conditions and that the developed approach can be used for regional-scale glacio-hydrological modeling.' article_number: '143' article_processing_charge: No article_type: original author: - first_name: René R. full_name: Wijngaard, René R. last_name: Wijngaard - first_name: Jakob F. full_name: Steiner, Jakob F. last_name: Steiner - first_name: Philip D.

In contact zones between the "Crab" and "Wave" ecotypes of the snail Littorina saxatilis divergent selection forms strong barriers to gene flow, while the role of postzygotic barriers due to selection against hybrids remains unclear. High embryo abortion rates in this species could indicate the presence of such barriers. Postzygotic barriers might include genetic incompatibilities (e.g. Dobzhansky-Muller incompatibilities) but also maladaptation, both expected to be most pronounced in contact zones. In addition, embryo abortion might reflect physiological stress on females and embryos independent of any genetic stress. We examined all embryos of >500 females sampled outside and inside contact zones of three populations in Sweden. Females' clutch size ranged from 0 to 1011 embryos (mean 130±123) and abortion rates varied between 0 and100% (mean 12%). We described female genotypes by using a hybrid index based on hundreds of SNPs differentiated between ecotypes with which we characterised female genotypes. We also calculated female SNP heterozygosity and inversion karyotype. Clutch size did not vary with female hybrid index and abortion rates were only weakly related to hybrid index in two sites but not at all in a third site. No additional variation in abortion rate was explained by female SNP heterozygosity, but increased female inversion heterozygosity added slightly to increased abortion. Our results show only weak and probably biologically insignificant postzygotic barriers contributing to ecotype divergence and the high and variable abortion rates were marginally, if at all, explained by hybrid index of females. article_processing_charge: No author: - first_name: Kerstin full_name: Johannesson, Kerstin last_name: Johannesson - first_name: Zuzanna full_name: Zagrodzka, Zuzanna last_name: Zagrodzka - first_name: Rui full_name: Faria, Rui last_name: Faria - first_name: Anja M full_name: Westram, Anja M id: 3C147470-F248-11E8-B48F-1D18A9856A87 last_name: Westram orcid: 0000-0003-1050-4969 - first_name: Roger full_name: Butlin, Roger last_name: Butlin citation: ama: 'Johannesson K, Zagrodzka Z, Faria R, Westram AM, Butlin R.

It is unknown whether proteins of the INM and ER are degraded through shared or distinct pathways in mammalian cells. We applied dynamic proteomics to profile protein half-lives and report that INM and ER residents turn over at similar rates, indicating that the INM’s unique topology is not a barrier to turnover. Using a microscopy approach, we observed that the proteasome can degrade INM proteins in situ. However, we also uncovered evidence for selective, vesicular transport-mediated turnover of a single INM protein, emerin, that is potentiated by ER stress. Emerin is rapidly cleared from the INM by a mechanism that requires emerin’s LEM domain to mediate vesicular trafficking to lysosomes. This work demonstrates that the INM can be dynamically remodeled in response to environmental inputs. article_processing_charge: No author: - first_name: Abigail full_name: Buchwalter, Abigail last_name: Buchwalter - first_name: Roberta full_name: Schulte, Roberta last_name: Schulte - first_name: Hsiao full_name: Tsai, Hsiao last_name: Tsai - first_name: Juliana full_name: Capitanio, Juliana last_name: Capitanio - first_name: Martin W full_name: HETZER, Martin W id: 86c0d31b-b4eb-11ec-ac5a-eae7b2e135ed last_name: HETZER orcid: 0000-0002-2111-992X citation: ama: 'Buchwalter A, Schulte R, Tsai H, Capitanio J, Hetzer M.

Application of controlled uniaxial pressure has recently been shown to more than double the transition temperature of the unconventional superconductor Sr2RuO4, leading to a pronounced peak in Tc versus strain whose origin is still under active debate. Here we develop a simple and compact method to passively apply large uniaxial pressures in restricted sample environments, and utilise this to study the evolution of the electronic structure of Sr2RuO4 using angle-resolved photoemission. We directly visualise how uniaxial stress drives a Lifshitz transition of the γ-band Fermi surface, pointing to the key role of strain-tuning its associated van Hove singularity to the Fermi level in mediating the peak in Tc. Our measurements provide stringent constraints for theoretical models of the strain-tuned electronic structure evolution of Sr2RuO4. More generally, our experimental approach opens the door to future studies of strain-tuned phase transitions not only using photoemission but also other experimental techniques where large pressure cells or piezoelectric-based devices may be difficult to implement. article_number: '46' article_processing_charge: Yes article_type: original arxiv: 1 author: - first_name: Veronika full_name: Sunko, Veronika id: 23cb1cf6-2c7a-11ef-91a4-f72fc19f20b3 last_name: Sunko orcid: 0000-0003-2724-3523 - first_name: Edgar full_name: Abarca Morales, Edgar last_name: Abarca Morales - first_name: Igor full_name: Marković, Igor last_name: Marković - first_name: Mark E. full_name: Barber, Mark E. last_name: Barber - first_name: Dijana full_name: Milosavljević, Dijana last_name: Milosavljević - first_name: Federico full_name: Mazzola, Federico last_name: Mazzola - first_name: Dmitry A. full_name: Sokolov, Dmitry A. last_name: Sokolov - first_name: Naoki full_name: Kikugawa, Naoki last_name: Kikugawa - first_name: Cephise full_name: Cacho, Cephise last_name: Cacho - first_name: Pavel full_name: Dudin, Pavel last_name: Dudin - first_name: Helge full_name: Rosner, Helge last_name: Rosner - first_name: Clifford W. full_name: Hicks, Clifford W. last_name: Hicks - first_name: Philip D.

The band exhibits steep dispersion near the Fermi level despite the fact that it is formed mainly by Pt \U0001D451 orbitals that are typically localized. We propose a picture based on two hidden kagome-lattice-like electronic structures: one originating from Pt \U0001D460+\U0001D45D\U0001D465/\U0001D45D\U0001D466 orbitals, and the other from Pt \U0001D4513⁢\U0001D4672−\U0001D45F2+\U0001D451\U0001D465⁢\U0001D466/\U0001D451\U0001D4652−\U0001D4662 orbitals, each placed on the bonds of the triangular lattice. In particular, we find that the underlying Pt \U0001D460+\U0001D45D\U0001D465/\U0001D45D\U0001D466 bands actually determine the steepness of the original dispersion, so that the large Fermi velocity can be attributed to the large width of the Pt \U0001D460+\U0001D45D\U0001D465/\U0001D45D\U0001D466 band. In addition, the kagome-like electronic structure gives rise to “orbital-momentum locking” on the Fermi surface, which reduces the electron scattering by impurities. We conclude that the combination of the large Fermi velocity and the orbital-momentum locking is likely to be the origin of the extremely small resistivity in PtCoO2." article_number: '045002' article_processing_charge: No article_type: original arxiv: 1 author: - first_name: Hidetomo full_name: Usui, Hidetomo last_name: Usui - first_name: Masayuki full_name: Ochi, Masayuki last_name: Ochi - first_name: Sota full_name: Kitamura, Sota last_name: Kitamura - first_name: Takashi full_name: Oka, Takashi last_name: Oka - first_name: Daisuke full_name: Ogura, Daisuke last_name: Ogura - first_name: Helge full_name: Rosner, Helge last_name: Rosner - first_name: Maurits W. full_name: Haverkort, Maurits W. last_name: Haverkort - first_name: Veronika full_name: Sunko, Veronika id: 23cb1cf6-2c7a-11ef-91a4-f72fc19f20b3 last_name: Sunko orcid: 0000-0003-2724-3523 - first_name: Philip D.

Using angle-resolved photoemission and first-principles-based surface space-charge calculations, we show how the induced quantum well sub-band states form multiple Fermi surfaces, which exhibit highly anisotropic Rashba-like spin splittings. We further show how the presence of both electronlike and holelike bulk carriers causes the near-surface band bending potential to develop an unusual nonmonotonic form, with spatially segregated electron accumulation and hole accumulation regions, which in turn amplifies the induced spin splitting. Our results thus demonstrate the novel environment that semimetals provide for tailoring electrostatically induced potential profiles and their corresponding quantum sub-band states. article_number: '045438' article_processing_charge: No article_type: original arxiv: 1 author: - first_name: O.

We give an introductory survey of the results in Yang and Zhao (Quiver varieties and elliptic quantum groups, 2017. arxiv1708.01418). We discuss a sheafified elliptic quantum group associated to any symmetric Kac-Moody Lie algebra. The sheafification is obtained by applying the equivariant elliptic cohomological theory to the moduli space of representations of a preprojective algebra. By construction, the elliptic quantum group naturally acts on the equivariant elliptic cohomology of Nakajima quiver varieties. As an application, we obtain a relation between the sheafified elliptic quantum group and the global affine Grassmannian over an elliptic curve.' acknowledgement: 'Y.Y. would like to thank the organizers of the MATRIX program Geometric R-Matrices: from Geometry to Probability for their kind invitation, and many participants of the program for useful discussions, including Vassily Gorbounov, Andrei Okounkov, Allen Knutson, Hitoshi Konno, Paul Zinn-Justin.

A steady-state approach is suited to analyze phenomena on the timescale of cell growth and circumvents the problem of incomplete experimental knowledge on kinetic laws and parameters, but it should be supported by a correct implementation of thermodynamic constraints. In this chapter, we review the latter aspect, highlighting its computational challenges and physical insights. The simple introduction of Gibbs inequalities avoids the presence of unfeasible loops allowing for correct timescale analysis, but leads to possibly non-convex feasible flux spaces whose exploration needs efficient algorithms. We briefly review the implementation of thermodynamics through variational principles in constraint-based models of metabolic networks. article_processing_charge: No arxiv: 1 author: - first_name: A full_name: De Martino, A last_name: De Martino - first_name: Daniele full_name: De Martino, Daniele id: 3FF5848A-F248-11E8-B48F-1D18A9856A87 last_name: De Martino orcid: 0000-0002-5214-4706 - first_name: E full_name: Marinari, E last_name: Marinari citation: ama: 'De Martino A, De Martino D, Marinari E.

Diese wichtige Aufgabe erfüllt das Axon, der „Ausgangsfortsatz“ der Nervenzelle. Für die schnelle Leitung des Aktionspotenzials sind sowohl die passiven Eigenschaften des axonalen Kabels als auch die aktiven Eigenschaften der Zellmembran von entscheidender Bedeutung. Die Evolution bedient sich zweier Tricks, um die Leitungsgeschwindigkeit des Aktionspotenzials zu maximieren. Der eine Trick ist die Zunahme des Axondurchmessers. Der andere Trick ist die Ausbildung von Markscheiden. Dies führt bei nahezu gleichem Platzbedarf zu einer Zunahme der Leistungsgeschwindigkeit um fast zwei Größenordnungen.

When insufficient, leptin levels fall, triggering compensatory increases in appetite. Falling leptin is first sensed by hypothalamic neurons, which then initiate adaptive responses. With regard to hunger, it is thought that leptin-sensing neurons work entirely via circuits within the central nervous system (CNS). Very unexpectedly, however, we now show this is not the case. Instead, stimulation of hunger requires an intervening endocrine step, namely activation of the hypothalamic–pituitary–adrenocortical (HPA) axis. Increased corticosterone then activates AgRP neurons to fully increase hunger. Importantly, this is true for 2 forms of low leptin-induced hunger, fasting and poorly controlled type 1 diabetes. Hypoglycemia, which also stimulates hunger by activating CNS neurons, albeit independently of leptin, similarly recruits and requires this pathway by which HPA axis activity stimulates AgRP neurons. Thus, HPA axis regulation of AgRP neurons is a previously underappreciated step in homeostatic regulation of hunger. article_processing_charge: Yes (in subscription journal) article_type: original author: - first_name: Rachel J. full_name: Perry, Rachel J. last_name: Perry - first_name: Jon M. full_name: Resch, Jon M. last_name: Resch - first_name: Amelia May Barnett full_name: Douglass, Amelia May Barnett id: de5f6fda-80fb-11ef-996f-a8c4ecd8e289 last_name: Douglass orcid: 0000-0001-5398-6473 - first_name: Joseph C. full_name: Madara, Joseph C. last_name: Madara - first_name: Aviva full_name: Rabin-Court, Aviva last_name: Rabin-Court - first_name: Hakan full_name: Kucukdereli, Hakan last_name: Kucukdereli - first_name: Chen full_name: Wu, Chen last_name: Wu - first_name: Joongyu D. full_name: Song, Joongyu D. last_name: Song - first_name: Bradford B. full_name: Lowell, Bradford B. last_name: Lowell - first_name: Gerald I. full_name: Shulman, Gerald I. last_name: Shulman citation: ama: Perry RJ, Resch JM, Douglass AM, et al.

The identity of the abelian group is a fractal composed of self-similar patches, and its limit is subject of extensive collaborative research. Here, we analyze the evolution of the sandpile identity under harmonic fields of different orders. We show that this evolution corresponds to periodic cycles through the abelian group characterized by the smooth transformation and apparent conservation of the patches constituting the identity. The dynamics induced by second and third order harmonics resemble smooth stretchings, respectively translations, of the identity, while the ones induced by fourth order harmonics resemble magnifications and rotations. Starting with order three, the dynamics pass through extended regions of seemingly random configurations which spontaneously reassemble into accentuated patterns. We show that the space of harmonic functions projects to the extended analogue of the sandpile group, thus providing a set of universal coordinates identifying configurations between different domains. Since the original sandpile group is a subgroup of the extended one, this directly implies that it admits a natural renormalization. Furthermore, we show that the harmonic fields can be induced by simple Markov processes, and that the corresponding stochastic dynamics show remarkable robustness over hundreds of periods. Finally, we encode information into seemingly random configurations, and decode this information with an algorithm requiring minimal prior knowledge. Our results suggest that harmonic fields might split the sandpile group into sub-sets showing different critical coefficients, and that it might be possible to extend the fractal structure of the identity beyond the boundaries of its domain.

More precisely, for any 1<q<(p+1)/2 we construct W1,q-bi-Sobolev maps with identity boundary conditions; for f∈L∞, we provide bi-Lipschitz maps. The basic building block of our construction are bi-Lipschitz maps which stretch a given compact subset of the unit square by a given factor while preserving the boundary. The construction of these stretching maps relies on a slight strengthening of the celebrated covering result of Alberti, Csörnyei, and Preiss for measurable planar sets in the case of compact sets. We apply our result to a model functional in nonlinear elasticity, the integrand of which features fast blowup as the Jacobian determinant of the deformation becomes small. For such functionals, the derivation of the equilibrium equations for minimizers requires an additional regularization of test functions, which our maps provide. article_processing_charge: No arxiv: 1 author: - first_name: Julian L full_name: Fischer, Julian L id: 2C12A0B0-F248-11E8-B48F-1D18A9856A87 last_name: Fischer orcid: 0000-0002-0479-558X - first_name: Olivier full_name: Kneuss, Olivier last_name: Kneuss citation: ama: Fischer JL, Kneuss O.

Here we identify a key biochemical and structural difference between CRY1 and CRY2 that underlies their differential strengths as transcriptional repressors. While both cryptochromes bind the BMAL1 transactivation domain with similar affinity to sequester it from coactivators, CRY1 is recruited with much higher affinity to the PAS domain core of CLOCK:BMAL1, allowing it to serve as a stronger repressor that lengthens circadian period. We identify a dynamic loop in the secondary pocket that regulates differential binding of cryptochromes to the PAS domain core. Notably, PER2 binding remodels this loop in CRY2 to enhance its affinity for CLOCK:BMAL1, explaining why CRY2 forms an obligate heterodimer with PER2, while CRY1 is capable of repressing CLOCK:BMAL1 both with and without PER2. article_processing_charge: No author: - first_name: Jennifer L. full_name: Fribourgh, Jennifer L. last_name: Fribourgh - first_name: Ashutosh full_name: Srivastava, Ashutosh last_name: Srivastava - first_name: Colby R. full_name: Sandate, Colby R. last_name: Sandate - first_name: Alicia full_name: Michael, Alicia id: 6437c950-2a03-11ee-914d-d6476dd7b75c last_name: Michael orcid: 0000-0002-6080-839X - first_name: Peter L. full_name: Hsu, Peter L. last_name: Hsu - first_name: Christin full_name: Rakers, Christin last_name: Rakers - first_name: Leslee T. full_name: Nguyen, Leslee T. last_name: Nguyen - first_name: Megan R. full_name: Torgrimson, Megan R. last_name: Torgrimson - first_name: Gian Carlo G. full_name: Parico, Gian Carlo G. last_name: Parico - first_name: Sarvind full_name: Tripathi, Sarvind last_name: Tripathi - first_name: Ning full_name: Zheng, Ning last_name: Zheng - first_name: Gabriel C. full_name: Lander, Gabriel C. last_name: Lander - first_name: Tsuyoshi full_name: Hirota, Tsuyoshi last_name: Hirota - first_name: Florence full_name: Tama, Florence last_name: Tama - first_name: Carrie L. full_name: Partch, Carrie L. last_name: Partch citation: ama: Fribourgh JL, Srivastava A, Sandate CR, et al.

The aim of this experiment was to try and extend the initial–final mass relation (IFMR) to somewhat higher masses, potentially challenging the Chandrasekhar limit currently thought to be around 1.38 M⊙. We discovered a particularly interesting white dwarf in the direction of the young ∼150 Myr old cluster Messier 47 (NGC 2422). All Gaia indicators (proper motion, parallax, location in the Gaia color–magnitude diagram) suggest that it is a cluster member. Its spectrum, obtained from Gemini-South, yields a number of anomalies: it is a DB (helium-rich atmosphere) white dwarf, it has a large magnetic field (2.5 MG), is of high mass (∼1.06 M⊙), and its colors are very peculiar—particularly the redder ones (r, i, z and y), which suggests that it may have a late-type companion. This may be the only magnetized, detached binary white dwarf with a non-degenerate companion of any spectral type known in or out of a star cluster. If the white dwarf is a cluster member, as all indicators suggest, its progenitor had a mass just over 6 M⊙. It may, however, be telling an even more interesting story than the one related to the IFMR, one about the origin of stellar magnetic fields, SNe I, and gravitational waves from low-mass stellar systems.' article_number: '75' article_processing_charge: No article_type: original arxiv: 1 author: - first_name: Harvey B. full_name: Richer, Harvey B. last_name: Richer - first_name: Ronan full_name: Kerr, Ronan last_name: Kerr - first_name: Jeremy full_name: Heyl, Jeremy last_name: Heyl - first_name: Ilaria full_name: Caiazzo, Ilaria id: 8ae5b6e7-2a03-11ee-914d-b58ed7a3b47d last_name: Caiazzo orcid: 0000-0002-4770-5388 - first_name: Jeffrey full_name: Cummings, Jeffrey last_name: Cummings - first_name: Pierre full_name: Bergeron, Pierre last_name: Bergeron - first_name: Patrick full_name: Dufour, Patrick last_name: Dufour citation: ama: Richer HB, Kerr R, Heyl J, et al.

Our use of short-wavelength photometry affords us an exceedingly clear view of stellar motions into the very center of the crowded core, yielding proper motions for >50,000 stars in the central 2′. We model the velocity dispersion profile of the cluster using an isotropic Jeans model. The density distribution is taken as a central IMBH point mass added to a combination of King templates. We individually model the general low-mass cluster objects (main sequence/giant stars), as well as the concentrated populations of heavy binary systems and dark stellar remnants. Using unbinned likelihood model fitting, we find that the inclusion of the concentrated populations in our model plays a crucial role in fitting for an IMBH mass. The concentrated binaries and stellar-mass black holes (BHs) produce a sufficient velocity dispersion signal in the core so as to make an IMBH unnecessary to fit the observations. We additionally determine that a stellar-mass BH retention fraction of 8.5% becomes incompatible with our observed velocities in the core. article_number: '1' article_processing_charge: No article_type: original arxiv: 1 author: - first_name: Christopher R. full_name: Mann, Christopher R. last_name: Mann - first_name: Harvey full_name: Richer, Harvey last_name: Richer - first_name: Jeremy full_name: Heyl, Jeremy last_name: Heyl - first_name: Jay full_name: Anderson, Jay last_name: Anderson - first_name: Jason full_name: Kalirai, Jason last_name: Kalirai - first_name: Ilaria full_name: Caiazzo, Ilaria id: 8ae5b6e7-2a03-11ee-914d-b58ed7a3b47d last_name: Caiazzo orcid: 0000-0002-4770-5388 - first_name: Swantje D. full_name: Möhle, Swantje D. last_name: Möhle - first_name: Alan full_name: Knee, Alan last_name: Knee - first_name: Holger full_name: Baumgardt, Holger last_name: Baumgardt citation: ama: Mann CR, Richer H, Heyl J, et al.
