description: In his 1971 interview with Henry La Brie, Percival L. Prattis discusses his path to becoming a journalist and provides an overview of the black press from its inception in 1827. He also discusses the differences between the white and black press, the role of the black press in the community as well as its role in assimilating black citizens into American society and sensitizing white Americans to the conditions of black Americans. Prattis shares his thoughts on his contributions to the field of journalism; black ownership of black newspapers; and changes in the black press in the late 1960s and early 1970s. He shares his thoughts on what the absence of the black press would mean for American society, the establishment of a national black press, and the role of black newspapers in the lives of black Americans.

description: Apparent stellar magnitudes observed at Maidanak observatory for SN2017ein - peculiarly faint core-collapse supernova rumored to have images of progenitor - are processed to get exact photometric data. Technique of photometry is described and the data itself is presented. Based on photometric data of B and R bands we used the regressional equation proposed by Lyman and Bersier to reconstruct the quasi-bolometric light curve. Reconstructed light curve has a peak luminosity of $3.3\cdot 10^{41} \rm{erg/s}$ which is almost an order of magnitude lower than typical values for such supernovae. Further, we used reconstructed bolometric values to estimate physical parameters using simple one-component models for photospheric and nebular phases. Fitting the models to reconstructed quasi-bolometric light curve allows us to estimate physical parameters. Such estimation yields $0.037 M_{\odot}$ for nickel-56 mass, $1.246 M_{\odot}$ for ejected mass and $1.641\cdot 10^{51}$ erg for final kinetic energy of ejecta. Ejecta mass looks very small for proposed progenitor candidate, but some explanations for such discrepancy are already proposed.

A Combined Electron Microscopy and Computational Study on Cellular Uptake and Stability of Carbon Nanotubes
Creators: name: Nerl, Hannah Catherine
Publisher: name: Imperial College London
Year: 2012

description: The aims of the PhD project were to understand the mechanisms of cellular uptake as well as the intracellular biostability of oxidised functionalised multi-walled carbon nanotubes (f- MWNTs). Firstly, high resolution transmission electron microscopy (HR TEM) imaging and 3D electron tomography were applied to study the pathways of f-MWNTs into non-phagocytic cells, and more specifically, to study the interaction between f-MWNTs and the cell membrane. After exposing epithelial cells to f-MWNTs for 24 hours, two distinct uptake processes by which NH3+ f-MWNTs can enter epithelial cells were observed. Then, the study was complemented using a combination of TEM imaging and coarse-grained molecular dynamics simulations, to provide insight into the interaction of f-MWNTs with cell membranes and the effect of surface charge on this interaction. Secondly, the question of whether f-MWNTs can be degraded by the body’s own defence mechanisms was addressed. HR TEM techniques were used to assess the graphitic structure and morphology of f-MWNTs injected into the murine brain and after exposure to human monocyte-derived macrophages (HMMs), with the aim of understanding the mechanisms underlying the degradation process. F-MWNTs were found to have a reduced biostability in the brain tissue and in the HMMs. Inside the brain tissue, the degradation occurred rapidly with signs of advanced f-MWNT degradation present after 2 days exposure. In the HMMs, f-MWNT walls were found to delaminate from individual f-MWNTs inside lysosomes after 24 hours exposure. Similar events were observed after 14 days exposure in the cell cytoplasm inside the HMMs. Furthermore, a loss of the graphitic structure was observed. By using scanning TEM electron energy loss spectroscopy (STEM EELS) to compare the near-edge structure of the carbon K-edge prior to, and post injection, graphitic f-MWNTs could be distinguished from the graphitic debris and the amorphous cell background. The combination of HR TEM and STEM EELS techniques provided information about the individual steps, leading to the disintegration of the f-MWNTs, and the morphology of the degradation debris. In order to study the effect of the functionalisation on the biostability, the study was repeated using pristine MWNTs and HMMs. No signs of degradation of the pristine MWNTs were observed after 14 days exposure to the HMMs.

description: We present a new class of binary words: the prefix normal words. They are defined by the property that for any given length $k$, no factor of length $k$ has more $a$'s than the prefix of the same length. These words arise in the context of indexing for jumbled pattern matching (a.k.a. permutation matching or Parikh vector matching), where the aim is to decide whether a string has a factor with a given multiplicity of characters, i.e., with a given Parikh vector. Using prefix normal words, we give the first non-trivial characterization of binary words having the same set of Parikh vectors of factors. We prove that the language of prefix normal words is not context-free and is strictly contained in the language of pre-necklaces, which are prefixes of powers of Lyndon words. We discuss further properties and state open problems.

description: The low wind effect is a phenomenon disturbing the phase of the wavefront in the pupil of a large telescope obstructed by spiders, in the absence of wind. It can be explained by the radiative cooling of the spiders, creating air temperature inhomogeneities across the pupil. Because it is unseen by traditional adaptive optics (AO) systems, thus uncorrected, it significantly degrades the quality of AO-corrected images. We provide a statistical analysis of the strength of this effect as seen by VLT/SPHERE after 4 years of operations. We analyse its dependence upon the wind and temperature conditions. We describe the mitigation strategy implemented in 2017: a specific coating with low thermal emissivity in the mid-infrared was applied on the spiders of Unit Telescope 3. We quantify the improvement in terms of image quality, contrast and wave front error using both focal plane images and measured phase maps.

On the invariance of the string partition function under duality

description: We consider the $N\!=\!1$ supersymmetric $σ$-model and we examine the transformation properties of the partition function under target-space duality. Contrary to what one would expect, we find that it is not, in general, invariant. In fact, besides the dilaton shift emerging from the Jacobian of the duality transformation of the bosonic part, there also exist a Jacobian for the fermionic part since fermions are also transform under the duality process. The latter is just the parity of the spin structure of the word sheet and since it cannot be compensated, the dual theory is not equvalent to the original one.

description: It has been suggested that the cycles of activity of X-ray Binaries (XrB) are triggered by a switch in the dominant disk torque responsible for accretion (paper I). As the disk accretion rate increases, the disk innermost regions would change from a jet-emitting disk (JED) to a standard accretion disk (SAD). While JEDs have been proven to successfully reproduce hard states (paper II), the existence of an outer cold SAD introduces an extra non local cooling term. We investigate the thermal structure and associated spectra of such a hybrid disk configuration. We use the 2T plasma code elaborated in paper II, allowing to compute outside-in the disk local thermal equilibrium with self-consistent advection and optically thin-to-thick transitions, in both radiation and gas supported regimes. The non-local inverse Compton cooling introduced by the external soft photons is computed by the BELM code. This additional term has a profound influence on JED solutions, allowing a smooth temperature transition from the outer SAD to the inner JED. We explore the full parameter space in disk accretion rate and transition radius, and show that the whole domain in X-ray fluxes and hardness ratios covered by standard XrB cycles is well reproduced by such hybrid configurations. Precisely, a reasonable combination of these parameters allows to reproduce the 3-200 keV spectra of five canonical XrB states. Along with X-ray signatures, JED-SAD configurations also naturally account for the radio emission whenever it is observed. By varying only the transition radius and the accretion rate, hybrid disk configurations combining an inner JED and an outer SAD are able to reproduce simultaneously the X-ray spectral states and radio emission of X-ray binaries during their outburst. Adjusting these two parameters, it is then possible to reproduce a full cycle. This will be shown in a forthcoming paper (paper IV).

Learning to Generalize towards Unseen Domains via a Content-Aware Style Invariant Model for Disease Detection from Chest X-rays

description: Performance degradation due to distribution discrepancy is a longstanding challenge in intelligent imaging, particularly for chest X-rays (CXRs). Recent studies have demonstrated that CNNs are biased toward styles (e.g., uninformative textures) rather than content (e.g., shape), in stark contrast to the human vision system. Radiologists tend to learn visual cues from CXRs and thus perform well across multiple domains. Motivated by this, we employ the novel on-the-fly style randomization modules at both image (SRM-IL) and feature (SRM-FL) levels to create rich style perturbed features while keeping the content intact for robust cross-domain performance. Previous methods simulate unseen domains by constructing new styles via interpolation or swapping styles from existing data, limiting them to available source domains during training. However, SRM-IL samples the style statistics from the possible value range of a CXR image instead of the training data to achieve more diversified augmentations. Moreover, we utilize pixel-wise learnable parameters in the SRM-FL compared to pre-defined channel-wise mean and standard deviations as style embeddings for capturing more representative style features. Additionally, we leverage consistency regularizations on global semantic features and predictive distributions from with and without style-perturbed versions of the same CXR to tweak the model's sensitivity toward content markers for accurate predictions. Our proposed method, trained on CheXpert and MIMIC-CXR datasets, achieves 77.32$\pm$0.35, 88.38$\pm$0.19, 82.63$\pm$0.13 AUCs(%) on the unseen domain test datasets, i.e., BRAX, VinDr-CXR, and NIH chest X-ray14, respectively, compared to 75.56$\pm$0.80, 87.57$\pm$0.46, 82.07$\pm$0.19 from state-of-the-art models on five-fold cross-validation with statistically significant results in thoracic disease classification.

description: Federated learning (FL) with over-the-air computation can efficiently utilize the communication bandwidth but is susceptible to analog aggregation error. Excluding those devices with weak channel conditions can reduce the aggregation error, but it also limits the amount of local training data for FL, which can reduce the training convergence rate. In this work, we jointly design uplink receiver beamforming and device selection for over-the-air FL over time-varying wireless channels to maximize the training convergence rate. We reformulate this stochastic optimization problem into a mixed-integer program using an upper bound on the global training loss over communication rounds. We then propose a Greedy Spatial Device Selection (GSDS) approach, which uses a sequential procedure to select devices based on a measure capturing both the channel strength and the channel correlation to the selected devices. We show that given the selected devices, the receiver beamforming optimization problem is equivalent to downlink single-group multicast beamforming. To reduce the computational complexity, we also propose an Alternating-optimization-based Device Selection and Beamforming (ADSBF) approach, which solves the receiver beamforming and device selection subproblems alternatingly. In particular, despite the device selection being an integer problem, we are able to develop an efficient algorithm to find its optimal solution.
 Simulation results with real-world image classification demonstrate that our proposed methods achieve faster convergence with significantly lower computational complexity than existing alternatives. Furthermore, although ADSBF shows marginally inferior performance to GSDS, it offers the advantage of lower computational complexity when the number of devices is large.

Domain Walls with Localised Gravity and Domain-Wall/QFT Correspondence

description: We review general domain-wall solutions supported by a delta-function source, together with a single pure exponential scalar potential in supergravity. These scalar potentials arise from a sphere reduction in M-theory or string theory. There are several examples of flat (BPS) domain walls that lead to a localisation of gravity on the brane, and for these we obtain the form of the corrections to Newtonian gravity. These solutions are lifted back on certain internal spheres to D=11 and D=10 as M-branes and D-branes. We find that the domain walls that can trap gravity yield M-branes or Dp-branes that have a natural decoupling limit, i.e. p\le 5, with the delta-function source providing an ultra-violet cut-off in a dual quantum field theory. This suggests that the localisation of gravity can generally be realised within a Domain-wall/QFT correspondence, with the delta-function domain-wall source providing a cut-off from the space-time boundary for these domain-wall solutions. We also discuss the form of the one-loop corrections to the graviton propagator from the boundary QFT that would reproduce the corrections to the Newtonian gravity on the domain wall.

Generalised Geometries for Type II and M Theory
Creators: name: Coimbra, Andre Janeiro
Publisher: name: Imperial College London
Year: 2012

description: In this thesis a new formulation is presented of the low energy, supergravity limit of type II string theory and M theory, including fermions to leading order. This is performed by utilising the language of generalised geometry, which is shown to be the natural setting for these theories. The core idea behind generalised geometry – an extension of ordinary differential geometry – and what makes it such a powerful tool for analysing supergravity, is that it recasts all the bosonic fields of the manifold as the natural geometric symmetries of an enlarged tangent space. There are two versions of generalised geometry which are of particular interest, namely O(d, d) generalised geometry which will be used to formulate the NSNS sector of type II theories, and Ed(d) generalised geometry (also known as exceptional generalised geometry) which enables the description of eleven-dimensional supergravity. For both cases, this work will show how one can introduce generalised connections to study the differential structure of the extended tangent spaces and define novel notions of generalised curvature. Specifying extra local structure defines a generalised notion of the Riemannian metric tensor, which contains all the relevant bosonic fields in a single, unified object. With these tools one can then reformulate the supergravity equations very naturally, as they become simply the generalised geometry analogue of Einstein gravity. One thus obtains a formalism which is automatically fully covariant under all the bosonic symmetries of supergravity. Furthermore, generalised connections are shown to be intimately related to supersymmetry, with important consequences for future applications. As an example, in the concluding chapter it will be shown how the classic problem of solving the Killing spinor equations of supersymmetric compactifications can be equivalently recast as the statement that the background possesses the generalised analogue of special holonomy.

description: While the performance of some emerging solar cell technologies is rocketing, there are other important parameters that also need to be considered for industrialization, including aesthetics, payback time or long-term stability. More specifically, aesthetical features of the solar cells play a very important role in the path towards the integration of these semi-transparent technologies into the buildings and windows of the future. In this work, we have implemented a theoretical methodology to study in depth colour tuning in polymer-based organic photovoltaic cells that uses experimentally complex refractive indices. We compare quantitatively basic interference effects (through active layer thickness), binaries with different donors and different acceptors, and ternary systems where the third component is either active or a simple dye. For hybrid perovskite solar cells, we compare the colour tuning capability of blending and alloying. Additionally, we show that the same theoretical framework can be employed for the so-called inverse problem, i.e. determining the best solar cell parameters (specific materials, donor:acceptor ratio and photoactive film thickness) that can reproduce a desired set of chromaticity coordinates.

Die Rechtsunsicherheit in Bezug auf die Ausübung dieses Rechts verschärfte die Bedenken hinsichtlich des Ausmaßes, in dem Textproduzenten Daten löschen müssen. Obwohl bestimmte technische Lösungen vielversprechend sind, um die Löschung von Daten zu erleichtern, reicht ihre Wirksamkeit allein nicht aus, um die Standards der DSGVO zu erfüllen.

description: The second half of the 20th century witnessed a pivotal moment with the integration of machines into daily life, catalysing the emergence of a data-driven ecosystem. This symbiotic relationship between big data and AI sparked significant advancements, notably in generative AI, elevating the intrinsic value of data. However, this exponential surge in data collection, processing, and storing to train text producers precipitated apprehensions concerning data protection, particularly the right to be forgotten, which aims at purging data from databases. The legal uncertainty surrounding the execution of this right exacerbated concerns regarding the extent to which text producers must erase data. Although certain technical solutions show promise in facilitating erasure, their efficacy alone falls short of meeting GDPR compliance standards. Crucially, comprehensive legal adaptions are imperative, ensuring that data subjects grasp the intricate interplay between legal and technical aspects of this right.

description: A recent paper on visualizing the sensitivity of hadronic experiments to nucleon structure [1] introduces the tool PDFSense which defines measures to allow the user to judge the sensitivity of PDF fits to a given experiment. The sensitivity is characterized by high-dimensional data residuals that are visualized in a 3-d subspace of the 10 first principal components or using t-SNE [2]. We show how a tour, a dynamic visualisation of high dimensional data, can extend this tool beyond 3-d relationships. This approach enables resolving structure orthogonal to the 2-d viewing plane used so far, and hence finer tuned assessment of the sensitivity.

description: Global issues of the Poisson-Lie T-duality are addressed. It is shown that oriented open strings propagating on a group manifold $G$ are dual to $D$-brane - anti-$D$-brane pairs propagating on the dual group manifold $\ti G$. The $D$-branes coincide with the symplectic leaves of the standard Poisson structure induced on the dual group $\ti G$ by the dressing action of the group $G$. T-duality maps the momentum of the open string into the mutual distance of the $D$-branes in the pair. The whole picture is then extended to the full modular space $M(D)$ of the Poisson-Lie equivalent $\si$-models which is the space of all Manin triples of a given Drinfeld double.T-duality rotates the zero modes of pairs of $D$-branes living on targets belonging to $M(D)$. In this more general case the $D$-branes are preimages of symplectic leaves in certain Poisson homogeneous spaces of their targets and, as such, they are either all even or all odd dimensional.

description: Precise relative localization is a crucial functional block for swarm robotics. This work presents a novel autonomous end-to-end system that addresses the monocular relative localization, through deep neural networks (DNNs), of two peer nano-drones, i.e., sub-40g of weight and sub-100mW processing power. To cope with the ultra-constrained nano-drone platform, we propose a vertically-integrated framework, from the dataset collection to the final in-field deployment, including dataset augmentation, quantization, and system optimizations. Experimental results show that our DNN can precisely localize a 10cm-size target nano-drone by employing only low-resolution monochrome images, up to ~2m distance. On a disjoint testing dataset our model yields a mean R2 score of 0.42 and a root mean square error of 18cm, which results in a mean in-field prediction error of 15cm and in a closed-loop control error of 17cm, over a ~60s-flight test. Ultimately, the proposed system improves the State-of-the-Art by showing long-endurance tracking performance (up to 2min continuous tracking), generalization capabilities being deployed in a never-seen-before environment, and requiring a minimal power consumption of 95mW for an onboard real-time inference-rate of 48Hz.

description: Exploring the role of conformal theories of gravity in string theory, we show that the minimal (N=2) gauged supergravities in five dimensions induce the multiplets and transformations of N=1 four dimensional conformal supergravity on the spacetime boundary. N=1 Poincare supergravity can be induced by explicitly breaking the conformal invariance via a radial cutoff in the 5d space. The AdS/CFT correspondence relates the maximal gauged supergravity in five dimensions to N=4 super Yang-Mills on the 4d spacetime boundary. In this context we show that the conformal anomaly of the gauge theory induces conformal gravity on the boundary of the space and that this theory, via the renormalization group, encapsulates the gravitational dynamics of the skin of asymptotically AdS spacetimes. Our results have several applications to the AdS/CFT correspondence and the Randall-Sundrum scenario.

description: Greene begins his 1971 interview with Henry La Brie by describing his youth, education, and work for the Illinois Central Railroad Corporation. He recounts his service during World War I. The conversation turns to Greene's return to the United States, where he learned the law as an apprentice and became involved with the Mississippi Negro Democrats and the National Association of Negro War Veterans. Greene details the racist threats he received after the debut of The Jackson Advocate and his role in the unseating of former Mississippi governor and senator Theodore Bilbo. Next, Greene goes on to criticise the civil rights movement and compares black newspapers in the North and South. Greene then discusses equality versus integration, what he sees as the natural law, and the future of the black newspaper. The interview concludes with Greene's discussions of the Compromise of 1877, meeting with Supreme Court Justice Hugo Lafayette Black, the evolution of newspapers during his lifetime, and the educational importance of daily news.
Negative Screenings in Liouville Theory

description: We demonstrate how negative powers of screenings arise as a nonperturbative effect within the operator approach to Liouville theory. This explains the origin of the corresponding poles in the exact Liouville three point function proposed by Dorn/Otto and $(\hbox{Zamolodchikov})^2$ (DOZZ) and leads to a consistent extension of the operator approach to arbitrary integer numbers of screenings of both types. The general Liouville three point function in this setting is computed without any analytic continuation procedure, and found to support the DOZZ conjecture. We point out the importance of the concept of free field expansions with adjustable monodromies - recently advocated by Petersen, Rasmussen and Yu - in the present context, and show that it provides a unifying interpretation for two types of previously constructed local observables.

description: We used line-of-sight magnetograms acquired by the Helioseismic and Magnetic Imager on board the Solar Dynamics Observatory to derive the decay rate of total unsigned magnetic flux for 910 ephemeral and active regions (ARs) observed between 2010 and 2017. We found that: i) most of the ARs obey the power law dependence between the peak magnetic flux and the magnetic flux decay rate, $DR$, so that $DR\sim Φ^{0.70}$; ii) larger ARs lose smaller fraction of their magnetic flux per unit of time than the smaller ARs; iii) there exists a cluster of ARs exhibiting significantly lower decay rate than it would follow from the power law and all of them are unipolar sunspots with total fluxes in the narrow range of $(2 - 8) \times 10^{21}$ Mx; iv) a comparison with our previous results shows that the emergence rate is always higher than the decay rate. The emergence rate follows a power law with a shallower slope than the slope of the decay-rate power law. The results allowed us to suggest that not only the maximum total magnetic flux determines the character of the decaying regime of the AR, some of the ARs end up as a slowly decaying unipolar sunspot; there should be certain physical mechanisms to stabilize such a sunspot.

description: In this work we propose two protocols to make an effective gauge potential for microwave photons in circuit QED. The schemes consist of coupled transmons whose flux are harmonically modulated in time. We investigate the effect of various types of capacitive and inductive couplings, and the role of the fixed phase offset of each site on the complex coupling rate between coupled qubits. These configurations can be directly realised in a superconducting circuit and is easily extendable to a scalable lattice. Due to the intrinsic non-linearity of the transmon qubits such lattices would be an ideal platform for simulating Bose-Hubbard Hamiltonians with non-trivial gauge fields.

Anomalous D-Brane Charge in F-Theory Compactifications

description: Tadpole cancellation in F-theory on an elliptic Calabi-Yau fourfold $X\to B_3$ demands some spacetime-filling three-branes (points in $B_3$). If moved to the discriminant surface, which supports the gauge group, and dissolved into a finite size instanton, the second Chern class of the corresponding bundle $E$ is expected to give a compensating contribution. However the dependence of D-brane charge on the geometry of $W$ and on the embedding $i: W\to B_3$ gives a correction to $c_2(E)$. We show how this is reconciled by considering the torsion sheaf $i_*E$ and discuss some integrality issues related to global properties of $X$ as well as the moduli space of this object.

description: Pomegranate peel extracts (PPE) were tested for the first time on BME-UV1, a valid cellular model to study the bovine mammary epithelial metabolism, to evaluate the effects on the oxidative stress and inflammatory status. Based on the statistical analysis of MTT data, PPE at 0.1, 1.0 and 10 μg/mL resulted not cytotoxic after 24 h, 48 h and 7 days of treatment. At the same concentrations, PPE induced a reduction of ROS production elicited by the addition of hydrogen peroxide or lipopolysaccharide evidencing an antioxidant effect confirmed also by a decrease of malondialdehyde. At 10 μg/mL, PPE reduced pro-inflammatory cytokines expressions showing an anti-inflammatory effect on BME-UV1 treated with lipopolysaccharide. Although in vivo experiments are necessary, the results of this study are promising for future applications of PPE as feed supplement for dairy cattle, in particular around calving, when the animals are more subject to oxidative stress and inflammatory diseases.

description: We discuss the discovery potential of the Dark-photons & Axion-Like particles Interferometer (DALI) in this letter. The apparatus, currently in a design and prototyping phase, will probe axion dark matter from the Teide Observatory, an environment protected from terrestrial microwave sources, reaching Dine--Fischler--Srednicki--Zhitnitsky-like axion sensitivity in the range 25--250 $μ$eV of mass. The experimental approach shows a potential to probe dark sector photons of kinetic mixing strength in excess of several $10^{-16}$, and to establish new constraints to a stochastic gravitational wave background in its band. We identify different branches, including cosmology, stellar, and particle physics, where this next-generation halo-telescope may play a role in coming years.

description: Correlation matrices are a major type of multivariate data. To examine properties of a given correlation matrix, a common practice is to compare the same quantity between the original correlation matrix and reference correlation matrices, such as those derived from random matrix theory, that partially preserve properties of the original matrix. We propose a model to generate such reference correlation and covariance matrices for the given matrix. Correlation matrices are often analysed as networks, which are heterogeneous across nodes in terms of the total connectivity to other nodes for each node. Given this background, the present algorithm generates random networks that preserve the expectation of total connectivity of each node to other nodes, akin to configuration models for conventional networks. Our algorithm is derived from the maximum entropy principle. We will apply the proposed algorithm to measurement of clustering coefficients and community detection, both of which require a null model to assess the statistical significance of the obtained results.

Is the additional increase of the star luminosity due to partial mixing real?

description: The partial mixing of matter between the radiative envelope and the convective core in the early type B--star produces an additional increase of star luminosity during the main sequence evolution. The high quality data on stellar mass and luminosity defined from the studies of detached double-lined eclipsing binaries are used to check the existence of such additional increase. It is shown that the additional luminosity increase does not contradict to the observed data of high quality, if the intensity of partial mixing is restricted by the observed increase in surface helium content.
Characterizing fragmentation and sub-Jovian clump properties in magnetized young protoplanetary disks

description: We study the initial development, structure and evolution of protoplanetary clumps formed in 3D resistive MHD simulations of self-gravitating disks. The magnetic field grows by means of the recently identified gravitational instability dynamo (Riols & Latter 2018; Deng et al. 2020). Clumps are identified and their evolution is tracked finely both backward and forward in time. Their properties and evolutionary path is compared to clumps in companion simulations without magnetic fields. We find that magnetic and rotational energy are important in the clumps' outer regions, while in the cores, despite appreciable magnetic field amplification, thermal pressure is most important in counteracting gravity. Turbulent kinetic energy is of a smaller scale than magnetic energy in the clumps. Compared to non-magnetized clumps, rotation is less prominent, which results in lower angular momentum in much better agreement with observations. In order to understand the very low sub-Jovian masses of clumps forming in MHD simulations, we revisit the perturbation theory of magnetized sheets finding support for a previously proposed magnetic destabilization in low-shear regions. This can help explaining why fragmentation ensues on a scale more than an order of magnitude smaller than that of the Toomre mass. The smaller fragmentation scale and the high magnetic pressure in clumps' envelopes explain why clumps in magnetized disks are typically in the super-Earth to Neptune mass regime rather than Super-Jupiters as in conventional disk instability. Our findings put forward a viable alternative to core accretion to explain widespread formation of intermediate-mass planets.
