description: Microstructural alterations in cortico-subcortical connections are thought to be present in obsessive–compulsive disorder (OCD). However, prior studies have yielded inconsistent findings, perhaps because small sample sizes provided insufficient power to detect subtle abnormalities. Here we investigated microstructural white matter alterations and their relation to clinical features in the largest dataset of adult and pediatric OCD to date. We analyzed diffusion tensor imaging metrics from 700 adult patients and 645 adult controls, as well as 174 pediatric patients and 144 pediatric controls across 19 sites participating in the ENIGMA OCD Working Group, in a cross-sectional case-control magnetic resonance study. We extracted measures of fractional anisotropy (FA) as main outcome, and mean diffusivity, radial diffusivity, and axial diffusivity as secondary outcomes for 25 white matter regions. We meta-analyzed patient-control group differences (Cohen’s d) across sites, after adjusting for age and sex, and investigated associations with clinical characteristics. Adult OCD patients showed significant FA reduction in the sagittal stratum (d = −0.21, z = −3.21, p = 0.001) and posterior thalamic radiation (d = −0.26, z = −4.57, p

description: As energy-conversion materials, organic–inorganic hybrid perovskites remain a research- and finance-intensive topic. However, even for the arguably most iconic representatives, methylammonium and formamidinium lead halides, the crystal structures of several polymorphs have remained undetermined. Herein, we describe the incommensurately modulated structure of MAPbBr3 in (3+1)D superspace, as deduced from single-crystal X-ray diffractometry despite systematic twinning. Affirming the published average space group, we determined the superspace group Imma(00γ)s00 with cell parameters of a = 8.4657(9), b = 11.7303(12), c = 8.2388(8) Å, and q = 0.2022(8)c*. Via group–subgroup and mode analyses using irreducible representations, we establish symmetry relationships to the well-known cubic and orthorhombic polymorphs and break down distortions into the average tilt system a–b0a– and modulated contributions to tilt and deformation of the PbBr6 coordination polyhedra. Not only does our model fill a long-standing gap in structural knowledge, but it may also serve as a starting point for elucidating other modulated structures within this substance class.
Radiative correction in approximate treatments of electromagnetic scattering by point and body scatterers

description: The transition-matrix ($T$-matrix) approach provides a general formalism to study scattering problems in various areas of physics, including acoustics (scalar fields) and electromagnetics (vector fields), and is related to the theory of the scattering matrix ($S$-matrix) used in quantum mechanics and quantum field theory. Focusing on electromagnetic scattering, we highlight an alternative formulation of the $T$-matrix approach, based on the use of the reactance matrix or $K$-matrix, which is more suited to formal studies of energy conservation constraints (such as the optical theorem). We show in particular that electrostatics or quasi-static approximations can be corrected within this framework to satisfy the energy conservation constraints associated with radiation. A general formula for such a radiative correction is explicitly obtained, and empirical expressions proposed in earlier studies are shown to be special cases of this general formula. This work therefore provides a justification of the empirical radiative correction to the dipolar polarizability and a generalization of this correction to any types of point or body scatterers of arbitrary shapes, including higher multipolar orders.

description: The aim of this poster is to explore how existing data management training and tools can be adapted by Astronomy Librarians for use in a library instructional session. Many drivers have contributed to the growing interest in data management planning, including increase funder requirements for data management plans with grant applications and an increased interest in libraries and information centers in supporting data curation services. Instruction is one avenue for engagement and outreach, and fits in nicely with the established tradition of librarians providing information literacy and bibliographic instruction in scientific resources.

description: We have analyzed mass wasting features, their distribution and deposit geometry on the two largest main asteroid belt objects—protoplanet Vesta and dwarf planet Ceres—and compared their geomorphology and mobility. Both asteroids have similar surface accelerations, but different surface compositions. Based on our observations and previous studies, we categorized three distinct morphological mass wasting classes: slumps, slides, and flow-like movements. We conclude that Ceres has abundant features of flow-like mass movements. Further, sliding and flow-like characteristics are identified in craters within mid-latitudes which supports the possibility of the presence of water ice in the near subsurface of Ceres. Vesta predominantly shows characteristics of dry granular-like slide features which are distributed homogenously across the surface. By plotting the ratio between fall height (H) and run-out length (L) (effective coefficient of friction, H/L) against the run-out length and spreading width (W), we demonstrate that deposits on Vesta terminate on shorter distances, whereas on Ceres they travel longer distances. The deposit geometry and the similar surface gravity on both asteroids suggest that the material composition and volatile component have a significant effect on deposit emplacement. However, both bodies’ mass movements have similar effective coefficients of friction, even though Vesta's regolith is comparatively dry, whereas Ceres is rich in water ice. This leads to the conclusion that volatile content alone cannot be responsible for low effective coefficients of friction, and that more than one geological process is needed to explain the mass motion behavior and morphology.
Tensor-force effects on single-particle levels and proton bubble structure around the $Z$ or $N=20$ magic number

description: Applying the semi-realistic $NN$ interactions that include realistic tensor force to the Hartree-Fock calculations, we investigate tensor-force effects on the single-particle levels in the Ca isotopes. The semi-realistic interaction successfully describes the experimental difference between $\varepsilon(p1s_{1/2})$ and $\varepsilon(p0d_{3/2})$ (denoted by $\mathitΔ\varepsilon_{13}$) both at $^{40}$Ca and $^{48}$Ca, confirming importance of the tensor force. The tensor force plays a role in the $N$-dependence of $\mathitΔ\varepsilon_{13}$ also in neutron-rich Ca nuclei. While the $p1s_{1/2}$-$p0d_{3/2}$ inversion is predicted in heavier Ca nuclei as in $^{48}$Ca, it takes place only in $N\geq 46$, delayed by the tensor force. We further investigate possibility of proton bubble structure in Ar, which is suggested by the $p1s_{1/2}$-$p0d_{3/2}$ inversion in $^{48}$Ca and more neutron-rich Ca nuclei, by the spherical Hartree-Fock-Bogolyubov calculations. Even with the inversion at $^{48}$Ca the pair correlation prohibits prominent bubble distribution in $^{46}$Ar. Bubble in Ar is unlikely also near neutron drip line because either of unboundness or of deformation. However, $^{34}$Si remains a candidate for proton bubble structure, owing to large shell gap between $p1s_{1/2}$ and $p0d_{5/2}$.

description: Here we study the comparative power of classical and quantum learners for generative modelling within the Probably Approximately Correct (PAC) framework. More specifically we consider the following task: Given samples from some unknown discrete probability distribution, output with high probability an efficient algorithm for generating new samples from a good approximation of the original distribution. Our primary result is the explicit construction of a class of discrete probability distributions which, under the decisional Diffie-Hellman assumption, is provably not efficiently PAC learnable by a classical generative modelling algorithm, but for which we construct an efficient quantum learner. This class of distributions therefore provides a concrete example of a generative modelling problem for which quantum learners exhibit a provable advantage over classical learning algorithms. In addition, we discuss techniques for proving classical generative modelling hardness results, as well as the relationship between the PAC learnability of Boolean functions and the PAC learnability of discrete probability distributions.

description: Asian mineral dust has been studied extensively for its role in affecting regional-to global-scale climate and for its deposits, which enable reconstructing Asian atmospheric circulation in the past. However, the timing and origin of the dust deposits remain debated. Numerous loess records have been reported across the Asian continent with ages varying from the Miocene to the Eocene and linked to various mechanisms including global cooling, Tibetan Plateau uplift and retreat of the inland proto-Paratethys Sea. Here, we study the Eocene terrestrial mudrocks of the Xining Basin in central China and use nonparametric end-member analysis of grain-size distributions to identify a loess-like dust component appearing in the record at 40 Ma. This is coeval with the onset of high-latitude orbital cycles and a shift to predominant steppe-desert vegetation as recognized by previous studies in the same record. Furthermore, we derive wind directions from eolian dune deposits which suggest northwesterly winds, similar to the modern-day winter monsoon which is driven by a high pressure system developing over Siberia. We propose that the observed shifts at 40 Ma reflect the onset of the Siberian High interacting with westerly derived moisture at obliquity timescales and promoting dust storms and aridification in central China. The timing suggests that the onset may have been triggered by increased continentality due to the retreating proto-Paratethys Sea.

description: The Landauer-Buettiker theory of mesoscopic conductors was recently extended to nanoelectromechanical systems. In this extension, the adiabatic reaction forces exerted by the electronic degrees of freedom on the mechanical modes were expressed in terms of the electronic S-matrix and its first non-adiabatic correction, the A-matrix. Here, we provide a more natural and efficient derivation of these results within the setting and solely with the methods of scattering theory. Our derivation is based on a generic model of a slow classical degree of freedom coupled to a quantum-mechanical scattering system, extending previous work on adiabatic reaction forces for closed quantum systems.

description: With strong and valid predictions, grasping a message is easy, whereas more demanding processing is required in the absence of robust expectations. We here demonstrate that brain correlates of the interplay between prediction and perception mechanisms in the understanding of meaningful sentences. Sentence fragments that strongly predict subsequent words induced anticipatory brain activity preceding the expected words; this potential was absent if context did not strongly predict subsequent words. Subjective reports of certainty about upcoming words and objective corpus-based measures correlated with the size of the anticipatory signal, thus establishing its status as a semantic prediction potential (SPP). Crucially, there was an inverse correlation between the SPP and the N400 brain response. The main cortical generators of SPP and N400 were found in inferior prefrontal cortex and posterior temporal cortex, respectively. Interestingly, sentence meaning was reflected by both measures, with additional category-specific sources of SPPs and N400s falling into parieto-temporo-occipital (visual) and frontocentral (sensorimotor) areas for animal- and tool-related words, respectively. These results show that the well-known brain index of semantic comprehension, N400, has an antecedent with different brain localization but similar semantic discriminatory function. We discuss whether N400 dynamics may causally depend on mechanisms underlying SPP size and sources.

description: Respiratory and heart rate are accessible physiological
signatures of human vitality. Unobtrusive insole ballistocardiography
using highly sensitive piezoelectric sensors promises
a wearable measurement system to monitor health throughout
the day. In this work, the 3D-printed ferroelectret insole is
worn by three participants while standing in upright posture.
The beat-to-beat detection implements a continuous wavelet
transform to filter the main frequency bands (6 to 8 Hz) in
the time-frequency domain, offering accurate heartbeat timings.
Amplitude and frequency variabilities in the heartbeat signal are
evaluated separately to reveal the underlying respiration. Both
instantaneous characteristics can be fused to obtain a robust
breath-to-breath measurement, mitigating body movements and
non-respiratory arrhythmia. The measured heart rate aligns well
with the reference from a commercial chest strap, and the heart
rate variability with ± 4 beats per minute is consistent with the
literature values of respiratory sinus arrhythmia. In conclusion,
the wearable insole concept with the presented signal processing
chain qualifies for remote health monitoring.
Evidence for a particle produced in association with weak bosons and decaying to a bottom-antibottom quark pair in Higgs boson searches at the Tevatron

description: We combine searches by the CDF and D0 Collaborations for the associated production of a Higgs boson with a W or Z boson and subsequent decay of the Higgs boson to a bottom-antibottom quark pair. The data, originating from Fermilab Tevatron p-pbar collisions at sqrt{s}=1.96 TeV, correspond to integrated luminosities of up to 9.7 fb^-1. The searches are conducted for a Higgs boson with mass in the range 100-150 GeV/c^2. We observe an excess of events in the data compared with the background predictions, which is most significant in the mass range between 120 and 135 GeV/c^2. The largest local significance is 3.3 standard deviations, corresponding to a global significance of 3.1 standard deviations. We interpret this as evidence for the presence of a new particle consistent with the standard model Higgs boson, which is produced in association with a weak vector boson and decays to a bottom-antibottom quark pair.

description: This article explores the potential of real-world labs (RWLs) and real-world experiments (RWEs) to be a fruitful addition to established approaches in urban planning in Germany. While transdisciplinary and transformative RWLs rooted in socio-ecological sustainability studies have become an important tool for experimenting with innovative solutions for environmental challenges in cities, RWLs aimed at improving social cohesion in neighbourhoods and fostering a communal life characterised by dialogue and solidarity are rare. To this latter aim, this article contributes with research experience from a transdisciplinary RWL on cooperative urban open space development seeking to foster social cohesion in super-diverse neighbourhoods in Germany. This article analyses the contradictory perceptions of the local stakeholders involved as regards the potentials of RWEs to be a meaningful addition to established planning practices. This article makes it clear that there is greater proximity between urban planning theory, practice, and RWEs than initially assumed. Nevertheless, RWEs have considerable potential as a positive complement to established approaches to urban planning and as a means of experimenting with open-ended encounter formats in neighbourhoods.
Partition Functions for Maxwell Theory on the Five-torus and for the Fivebrane on S1XT5

description: We compute the partition function of five-dimensional abelian gauge theory on a five-torus T5 with a general flat metric using the Dirac method of quantizing with constraints. We compare this with the partition function of a single fivebrane compactified on S1 times T5, which is obtained from the six-torus calculation of Dolan and Nappi. The radius R1 of the circle S1 is set to the dimensionful gauge coupling constant g^2= 4π^2 R1. We find the two partition functions are equal only in the limit where R1 is small relative to T5, a limit which removes the Kaluza-Klein modes from the 6d sum. This suggests the 6d N=(2,0) tensor theory on a circle is an ultraviolet completion of the 5d gauge theory, rather than an exact quantum equivalence.

description: We investigate the influence of grain boundaries (GBs), line defects (LDs), and chirality on thermal transport in graphene using non-equilibrium Green's functions. At room temperature the ballistic thermal conductance is ~4.2 GW/m^2/K, and single GBs or LDs yield transmission from 50-80% of this value. LDs with carbon atom octagon defects have lower thermal transmission than GBs with pentagon and heptagon defects. We apply our findings to study the thermal conductivity of polycrystalline graphene for practical applications, and find that the type and size of GBs play an important role when grain sizes are smaller than a few hundred nanometers.

description: We investigate the role of electron-electron interaction in a two-band Hubbard model based on the Bernevig-Hughes-Zhang Hamiltonian exhibiting the quantum spin Hall (QSH) effect. By means of dynamical mean-field theory, we find that a system with topologically trivial non-interacting parameters can be driven into a QSH phase at finite interaction strength by virtue of local dynamical fluctuations. For very strong interaction, the system reenters a trivial insulating phase by going through a Mott transition. We obtain the phase diagram of our model by direct calculation of the bulk topological invariant of the interacting system in terms of its single particle Green's function.

description: Health and the capacity to flourish are deeply intertwined. For members of vulnerable migrant groups, systemic inequalities and structural forms of marginalisation and exclusion create health risks, impede access to needed care and interfere with the ability to achieve one’s full potential. Migrants often have limited access to healthcare, and they frequently are portrayed as less deserving than others of the resources needed to lead a healthy and flourishing life. Under these circumstances, clinicians, healthcare institutions and global health organisations have a moral and ethical obligation to consider the role they can—and do—play in either advancing or impeding migrants’ health and their capacity to flourish. Drawing on case studies from three world regions, we propose concrete steps clinicians and health institutions can take in order to better serve migrant patients. These include recommendations that can help improve understanding of the complex circumstances of migrants’ lives, strengthen collaboration between care providers and non-medical partners and transform the social, economic and structural circumstances that impede flourishing and harm health. Developing new strategies to promote the flourishing of precarious migrants can strengthen our collective ability to re-envision and redesign health systems and structures to value the health, dignity and bodily integrity of all patients—especially the most vulnerable—and to promote flourishing for all.

 Chilodontopsis hisioensis Ozaki & Yagiu, 1941: 171, Pl. II fig. 4. Zosterodasys hisioensis – Jankowski 2007: 729 (combining author). Zosterodasys texensis Alekperov et al., 2007 /8: 111, fig. 6B.
 Diagnosis. Size about 150–230 × 55–75 µm in vivo. Body shape obovate to elliptical with left margin anteriorly slightly projecting. Macronucleus ellipsoidal with a single globular micronucleus. One large posterior contractile vacuole accompanied by 4–5 small ones. About 80 ciliary rows: 45–47 ventral and 30–36 dorsal. Synhymenium incompletely encircles cell. On average 19 (16–22) nematodesmal rods. Marine.
 Type locality. Under cyanobacterial layer in saltwater ditches near the Onomiti Channel, Japan.
 Type material. Deposition of type material not mentioned by Ozaki & Yagiu (1941). Alekperov et al. (2007/8) deposited one holotype and two paratype slides with protargol impregnated specimens of Z. texensis in the Institute of Zoology, NAS of Azerbaijan, Baku City.
 Etymology. Not given in the original description. We do not know the derivation of “ hisioensis ” but suppose that it is a Latinized Japanese place name.
 Remarks. We suggest to synonymize Z. texensis with Z. hisioensis because diagnostic features of these two species are similar or overlap considerably. This concerns the body shape and size (150–200 × 70–75 µm in Z. hisioensis and 180–230 × 55–65 µm in Z. texensis), the nuclear and contractile vacuole apparatus as well as the number of the nematodesmal rods (16 in Z. hisioensis and 18–22 in Z. texensis). The number of the ciliary rows was not studied in Z. hisioensis by Ozaki & Yagiu (1941). Alekperov et al. (2007/8) discovered Z. texensis on aquatic plants in shallow bays of the Mexican Gulf.

description: In a recent paper arXiv:1107.5048, we discussed the correlation between the elastic neutralino-nucleon scattering cross section, constrained by dark matter direct detection experiments, and fine-tuning at tree-level in the electroweak symmetry breaking sector of the Minimal Supersymmetric Standard Model (MSSM). Here, we show that the correlation persists in the Next-to-Minimal Supersymmetric Standard Model (NMSSM), and its variant, lambda-SUSY. Both models are strongly motivated by the recent discovery of a 125 GeV Higgs-like particle. We also discuss the implications of the recently published bound on the direct detection cross section from 225 live days of XENON100 experiment. In both the MSSM and the NMSSM, most of the parameter space with fine-tuning less than 10% is inconsistent with the XENON100 bound. In lambda-SUSY, on the other hand, large regions of completely natural electroweak symmetry breaking are still allowed, primarily due to a parametric suppression of fine-tuning with large λ. The upcoming XENON1T experiment will be able to probe most of the parameter space with less than 1% fine-tuning in all three models.

description: We employ realistic constraints on astrophysical and instrumental selection effects to model the Gamma-Ray Burst (GRB) redshift distribution using {\it Swift} triggered redshift samples acquired from optical afterglows (OA) and the TOUGH survey. Models for the Malmquist bias, redshift desert, and the fraction of afterglows missing because of host galaxy dust extinction, are used to show how the "true" GRB redshift distribution is distorted to its presently observed biased distribution. We also investigate another selection effect arising from a correlation between $E_{\rm iso}$ and $L_{\rm opt}$. The analysis, which accounts for the missing fraction of redshifts in the two data subsets, shows that a combination of selection effects (both instrumental and astrophysical) can describe the observed GRB redshift distribution. Furthermore, the observed distribution is compatible with a GRB rate evolution that tracks the global SFR, although the rate at high-$z$ cannot be constrained with confidence. Taking selection effects into account, it is not necessary to invoke high-energy GRB luminosity evolution with redshift to explain the observed GRB rate at high-$z$.

description: This article develops a typology of anchoring practices of public connection to systematize how new forms of interaction, participation, and articulation in networked media now challenge the primacy of journalism to offer exclusive and authoritative representations of society. The first part offers a brief summary of core contributions and assumptions in practice theory, highlighting differences between strong and weak programs of practice-based research. The second part presents the concept of public connection and how it can be expanded to include media practice on a more general, analytic level. The third part discusses four sets of anchoring practices, which allow for very different intensities of public connection to emerge: practices of information retrieval, social orientation, (self-)representation, and public intervention. The concluding outlook section addresses challenges for the study of journalism, focusing on the relations between professional and nonprofessional practices of articulation, in which speaker and audience positions can alternate dynamically between different “layers of publicness.”

description: This article presents a framework that reconciles the requirements of computational methods with a qualitative, phenomenological approach to the analysis of audiovisual media. In its temporality and multimodality we treat audiovisual media as exemplary with regard to the wider field of performative arts and their analysis in digital humanities approaches. First, we argue in favor of grounding digital methodology explicitly in scholarly, theoretical approaches to the human experience of performative arts and outline a qualitative approach to compositional patterns and dynamics of affect in audio-visual media. To demonstrate this approach, an exemplary scene analysis highlights the specifics of analyzing experiential qualities based on micro-level descriptions of compositional structures. Eventually, the main body of the article spells out three central challenges with regard to this use of computational tools: 1.) recasting common film analytical vocabulary into a machine readable semantic ontology; 2.) setting up a systematic and applicable annotation routine that is based on the developed semantic ontology and allows for the interpersonal and consistent description of larger corpora; 3.) developing visualizations and query tools that enable the identification and tracing of compositional patterns within complex sets of annotation data. The article concludes by demonstrating the benefits of visualized annotation data by taking up the exemplary analysis sketched out earlier and, ultimately, reflects upon the implications of the outlined AdA filmontology as a programmatic starting point to addressing intersubjective bases of experience in the wider field of digital humanities.

description: In a recently proposed computational model of open molecular systems out of equilibrium the action of different reservoirs enters as a linear sum into the Liouville-type evolution equations for the open system's statistics. The linearity of the coupling is common to different mathematical models of open systems and essentially relies on neglecting the feedback of the system onto the reservoir due to their interaction. In this paper, the range of applicability of the computational model is tested with a linear coupling to two different reservoirs, which induces a nonequilibrium situation. To this end, the density profiles of Lennard–Jones liquids in large thermal gradients are studied using nonequilibrium molecular dynamics simulations with open boundaries. The authors put in perspective the formulation of an extension of the mathematical model that can account for nonlinear effects.

(Figs 7 A–G)
 Zosterodasys kryophilus Petz et al., 1995: 59, fig. 18; Jankowski 2007: 729; Wilbert & Song 2008: 980. Zosterodasys sp. – Agatha et al. 1993: 265, fig. 6.
 Diagnosis. Size about 100–170 × 50–60 µm in vivo. Body shape obovate to elliptical with left margin anteriorly slightly projecting. Macronucleus ellipsoidal with a single globular micronucleus. About 6–9 contractile vacuoles evenly spaced along left postoral and posterior right body margin. On average 57 ciliary rows: 25–36 ventral and 21–33 dorsal. Synhymenium incompletely encircles cell. On average 22 (17–26) nematodesmal rods. Marine.
 Type locality. Pancake sea ice of Weddell Sea, Antarctica, W7°19' S69°26'.
 Type material. One holotype (syntype?) slide (registration number 2001/150) and one paratype slide (registration number 2001/54) with protargol-impregnated specimens were deposited in the Biology Centre of the Museum of Upper Austria, Linz (LI).
 Etymology. Composite of the Greek noun krýos (κρύ⁰ς; frost, ice) and the Greek verb philein (φlƛεlν, to love), referring to the habitat in which the species was discovered.
 Remarks. We tentatively suggest to affiliating the single specimen of Zosterodasys sp. found by Agatha et al. (1993) in the Arctic sea ice with Z. kryophilus. Both have a similar body size in protargol preparations (133 µm in Zosterodasys sp. and on average 150 µm in Zosterodasys kryophilus) and number of the ciliary rows (about 40–50 in Zosterodasys sp. and 46–69 in Z. kryophilus). The single seeming difference between them would be the number of the nematodesmal rods (17–26 in Z. kryophilus vs. 11 in Zosterodasys sp. according to the description of Agatha et al. 1993). However, according to the figure provided (Fig. 7 E), the single specimen studied by Agatha et al. (1993) displays 16 nematodesmal rods, a value near the lower limit of Z. kryophilus. On the other hand, the conspicuously long preoral area of Zosterodasys sp. can be a rostrum, indicating that it is a misidentified Orthodonella apohamatus, a marine synhymeniid ciliate described by Lin et al. (2004). Therefore, data of Agatha et al. (1993) are not incorporated into the diagnosis of Z. kryophilus.

Sagrid-2.0 : Tooling Up For African Collaboration
Creators: name: Becker, Bruce

description: he South African National Grid (SAGrid) is a federation of universities, national laboratories and research groups which operates a distributed computing infrastructure. Starting in 2009 and initially based on gLite-3.2 middleware, SAGrid allowed better participation to WLCG and other large distributed e-Infrastructures. However, a long tail of individual researchers in South Africa and the rest of the region were excluded or poorly-served. With the evolution of grid and maturity of cloud middleware, the potential of the infrastructure has increased. With the support of the CHAIN-REDS project, a signature of a Resource Infrastructure Provider MoU with EGI.eu has also improved interoperation, collaboration and reliability of the infrastructure.

In this contribution, we report on how we further improve the usability and sustainability of the infrastructure by adopting new methodologies and technologies  to support technical and user communities. While still offering a "grid" infrastructure, SAGrid is now also offers user- and developer-friendly interfaces to new services, while the adoption of executable infrastructure improves reliability and scalability of operations.

description: H3K9 methylation maintains cell identity orchestrating stable silencing and anchoring of alternate fate genes within the heterochromatic compartment underneath the nuclear lamina (NL). However, how cell type–specific genomic regions are specifically targeted to the NL is still elusive. Using fibro-adipogenic progenitors (FAPs) as a model, we identified Prdm16 as a nuclear envelope protein that anchors H3K9-methylated chromatin in a cell-specific manner. We show that Prdm16 mediates FAP developmental capacities by orchestrating lamina-associated domain organization and heterochromatin sequestration at the nuclear periphery. We found that Prdm16 localizes at the NL where it cooperates with the H3K9 methyltransferases G9a/GLP to mediate tethering and silencing of myogenic genes, thus repressing an alternative myogenic fate in FAPs. Genetic and pharmacological disruption of this repressive pathway confers to FAP myogenic competence, preventing fibro-adipogenic degeneration of dystrophic muscles. In summary, we reveal a druggable mechanism of heterochromatin perinuclear sequestration exploitable to reprogram FAPs in vivo.
