description: One of the main goals of gravitational-wave astrophysics is to study gravity in the strong-field regime and constrain deviations from general relativity (GR). Any such deviation affects not only binary dynamics and gravitational-wave emission but also the structure and tidal properties of compact objects. In the case of neutron stars, masses, radii, and tidal deformabilities can all differ significantly between different theories of gravity. Currently, the measurement uncertainties in neutron star radii and tidal deformabilities are quite large. However, much less is known about how the large uncertainty in the nuclear equation of state (EOS) might affect tests of GR using binary neutron star mergers. Conversely, using the wrong theory of gravity might lead to incorrect constraints on the nuclear EOS. Here, we study this problem within scalar-tensor (ST) theory. We apply the recently derived $\ell = 2$ tidal Love numbers in this theory to parameter estimation of GW170817. Correspondingly, we test if physics beyond GR could bias measurements of the nuclear EOS and neutron star radii. We find that parameter inference for both the GR and ST cases return consistent component masses and tidal deformabilities. The radius and the EOS posteriors, however, differ between the two theories, but neither is excluded by current observational limits. This indicates that measurements of the nuclear EOS may be biased and that deviations from GR could go undetected when analyzing current binary neutron star mergers.

description: We recently questioned the treatment of a dust particle as a perfect absorber for electrons and ions and proposed a surface model for the charge of a dust particle in a quiescent plasma which combines the microscopic physics at the grain boundary (sticking into and desorption from external surface states) with the macrophysics of the discharge (plasma collection fluxes). Within this model the charge and partial screening of the particle can be calculated without relying on the condition that the total electron collection flux balances on the grain surface the total ion collection flux. Grain charges obtained from our approach compared favorably with experimental data. The purpose of this paper is to describe our model in more detail, in particular, the hypotheses on which it is built, contrast it with the standard charging models based on flux balancing on the grain surface, and to analyze additional experimental data.

description: Violent relaxation -- the protocluster dynamical response to the expulsion of its leftover star forming gas -- is a short albeit crucial episode in the evolution of star clusters and star cluster systems. In this contribution, I survey how it influences the cluster age distribution, the cluster mass function and the ratio between the cluster mass and the stellar mass. I highlight the promising potential that the study of this phase holds in terms of deciphering star cluster formation and galaxy evolution, and (some of) the issues which are to be dealt with before achieving this goal.

description: We present a theoretical model and simulation for the formation dynamics of diverse texture patterns that emerge spontaneously or self-organize during phase inversion processes of fresh cream by mechanical whipping. The results suggest that the model should be applied for theoretically designing the texture and quality of whipped cream and butter products. The modeling complexity in phase inversion processes from fresh cream via whipped cream to butter was overcome by using a well-established complex systems approach, coupled map lattice (CML). The proposed CML consists of a minimal set of procedures (i.e., parameterized nonlinear maps), whipping, coalescence, and flocculation, acting on the appropriately coarse-grained field variables, surface energy, cohesive energy, and velocity (flow) of the emulsion defined on a two-dimensional square lattice. In the CML simulations, two well-known and different phase inversion processes are reproduced at high and low whipping temperatures. The overrun and viscosity changes simulated in these processes are at least qualitatively consistent with those observed in experiments. We characterize these processes exhibiting different texture patterns as the viscosity dominance at high whipping temperature and as the overrun dominance at low whipping temperature on the viscosity-overrun plane, which is one of the state diagrams.

description: A análise sobre o patriarcalismo e sua influência na sociedade brasileira revela a necessidade urgentede desconstruir o machismo enraizado em nossas estruturas socioculturais. A desconstrução do machismoé fundamental para promover a igualdade de gênero e combater a violência contra as mulheres.Ao longo da história, o patriarcalismo tem sido uma força dominante que sustenta e perpetua adesigualdade de gênero. Essa estrutura hierárquica, onde o homem é considerado o chefe e provedor dafamília, tem suas raízes tanto na história colonial quanto na influência cultural-religiosa, especialmente docatolicismoA relação entre patriarcalismo, colonialismo e catolicismo moldou nossas estruturas sociais eculturais,criando sistemas de poder complexos que naturalizam e perpetuam comportamentos machistas.Esses sistemas contribuem para taxas alarmantes de violência de gênero, refletidas em casos defeminicídio e outras formas de violência doméstica. O aumento dos homicídios femininos evidencia aurgência de políticas públicas mais eficazes para enfrentar a violência de gênero. Essas políticas devemincluir não apenas a punição de agressores, mas também a implementação de programas educacionaise de conscientização para desconstruir padrões culturais machistas.Portanto, é crucial que a sociedade brasileira se empenhe na desconstrução do machismo, promovendouma cultura de respeito, igualdade e segurança para todas as mulheres. Isso requer não apenasmudanças institucionais, mas também uma mudança de mentalidade em todos os níveis da sociedade.Bourdieu argumenta que a dominação masculina não é apenas uma questão individual, mas estáenraizada nas estruturas sociais e culturais mais amplas da sociedade. Isso significa que o machismo nãoé apenas um comportamento individual, mas sim um sistema complexo de hierarquias e normas sociaisque perpetuam a desigualdade de gênero.

description: Text-to-video (T2V) generation has been recently enabled by transformer-based diffusion models, but current T2V models lack capabilities in adhering to the real-world common knowledge and physical rules, due to their limited understanding of physical realism and deficiency in temporal modeling. Existing solutions are either data-driven or require extra model inputs, but cannot be generalizable to out-of-distribution domains. In this paper, we present PhyT2V, a new data-independent T2V technique that expands the current T2V model's capability of video generation to out-of-distribution domains, by enabling chain-of-thought and step-back reasoning in T2V prompting. Our experiments show that PhyT2V improves existing T2V models' adherence to real-world physical rules by 2.3x, and achieves 35% improvement compared to T2V prompt enhancers.

description: The potential impact of artificial intelligence on graphic design has, in
 recent years, stimulated a range of questions and concerns from design
 practitioners and academics about the future of AI-driven designs. This
 impact has prompted researchers, academics and practitioners alike to
 rethink the new implication of AI on the role of the graphic designer in
 this progression. It has also led to consideration of a plethora of issues
 and challenges around academia and practice, addressing questions
 associated with the definition of creativity, cultural acceptance, and
 ethical issues, besides possibilities that AI can imply in having
 autonomous AI-driven designs.

 In this research, I investigate the impact of AI from the graphic
 designers' perspective measuring the impact on their roles as
 designers in the design process, including an assessment of how to use AI
 as a self-governed system to generate visual designs autonomously rather
 than having AI as an application tool. This investigation will propose a
 new literature of theory and practice into the process of designing,
 particularly exploring and speculating upon new opportunities associated
 with combining data and algorithms with graphic design, in practice as
 well as in education. Co-design activities and semi-structured interviews
 were used in this research to initiate speculative provocative discussions
 and debates. In addition, this thesis presents the ADI card toolkit, a
 speculative design toolkit designed to help initiate collaboration in
 brainstorming and generate solutions to these challenges by using the
 gameplay approach. The ADI card toolkit was tested as part of conducting
 the research in Saudi Arabia, a country undergoing a transformation in
 terms of employing the 4th industrial revolution of technology and
 innovation towards building their infrastructure, economy, and quality of
 life under the government’s Vision 2030. The findings suggest many actions
 to consider when using AI in education and practice one of which is
 equipping graphic designers with knowledge, skills and qualifications to
 be furtherly open and aware of the broad spectrum of AI potentials which
 allows for proactive collaboration as a self-driven system with graphic
 designers. The research also suggests using gameplay as an approach when
 introducing AI tools in academia which can aid in exploring opportunities
 to alternate the human–machine entanglements and enable designer and
 academics alike to explore self-generated designs and alternative futures
 in this field.

description: For a quasi-two-dimensional nonlinear sigma model on the real Stiefel manifolds with a generalized (anisotropic) metric, the equations of a two-charge renormalization group (RG) for the homothety and anisotropy of the metric as effective couplings are obtained in a one-loop approximation. Normal coordinates and the curvature tensor are exploited for the renormalization of the metric. The RG trajectories are investigated and the presence of a fixed point common to four critical lines or four phases (tetracritical point) in the general case, or its absence in the case of an Abelian structure group, is established. For the tetracritical point, the critical exponents are evaluated and compared with those known earlier for a simpler particular case.

description: To have a thesis, one must have a problem. This improvement of methods and means of the teaching of the students and supervision of the floor is always a problem in any teaching hospital. Although it is a problem which deserves the deepest attention and action from experienced workers and leaders, it is nonetheless one that is vital and almost insidious in gripping the interest of those for whom teaching and supervising, as well as the betterment of their hospital holds an attraction. No method of supervision in teaching is going to function with any marked degree of success until there is an improvement of the physical plant and additional personnel. This study has been done wholly at the Multnomah and Doernbecher Hospitals.

description: Motivation: The ongoing COVID-19 pandemic has been accompanied by tens of thousands of scientific publications relating to all aspects of the disease, with many more added daily. This publication rate is leaving researchers unable to keep up with new findings, which they rely on to inform their work in understanding and combating SARS-Cov-2. Researchers investigating novel drug candidates with in-silico drug discovery efforts work with vast numbers of potential compounds, changing and incompletely characterized protein targets, varying cellular contexts, and limited established information. So they especially rely on scientific insights from the literature to guide their efforts toward the most fruitful directions. To keep pace with the literature, these researchers need more capable tools to get the information they seek.
Results: In ongoing work, we are developing and applying Natural Language Processing (NLP) techniques for locating and filtering relevant information from the literature, to help accelerate drug discovery research. These techniques go beyond traditional text search tools by incorporating context and semantics, supporting targeted filtering, and leveraging external resources. We apply embedding-expanded search, sentence classification, and text similarity techniques in a unified platform for drug discovery researchers that supports querying the database and offline filtering of relevant topics.
The Canadian response to the Irish famine emigration of 1847
Creators: name: Harvey, Leslie Anne
Publisher: name: University of British Columbia

description: In 1847, 215,000 Irish fled their famine-stricken and diseased homeland, and of this number, some 90,000 headed for the shores of Canada. It was both the largest and most diseased and destitute emigration that Canada had ever received, and it caught the colony almost totally by surprise. Many Canadians had been able to follow the course of the potato blight and famine in Ireland, but very few appeared to have considered their impact on the emigration to Canada. They had the assurances of those best informed about the condition of Ireland, the Imperial Government, that, no extraordinary measures would be needed; why should their word be doubted? In the first weeks of the Immigration season, Canadians discovered that the Imperial authorities were wrong; the colony found itself forced to deal with an abnormal immigration with only the meagrest preparations, Canadian emigration officials spent the rest of the season attempting to recover from the shock of those first weeks; all they could do was attempt to. relieve the sufferings of the immigrants to the best of their ability. Stop-gap relief measures were authorized by the Canadian Government for as long as distress and disease were prevalent; private charitable institutions stepped in to provide shelter and care for the helpless among the immigrants. In the end, the colony succeeded, despite its financial difficulties, both in enabling the Irish to regain their health and in making them producing members of the community, something which few Canadians, at the height of the crisis, felt would be possible. This successful 'absorption' of the immigrants, however, had been accomplished only with difficulty and at great cost. This thesis examines the Canadian response, and particularly that of the various levels of government, to the immigration crisis which it faced in 1847 and the strains which this crisis placed upon the relations of the Imperial and Colonial governments.

description: Severe Acute Respiratory Syndrome Coronavirus 2 (SARS-CoV2) is the virus type that causing the novel pandemic coronavirus disease (COVID-19). The pandemic status was given by World Health Organization (WHO) on March 2020 during the rapid increase of numerous cases of infection and death outside its original site in Wuhan, China starting from December 2019 that has affected across China and worldwide. Therefore, a strategy of early accurate case identification is crucial to controlling the pandemic. Here, we used sequencing data to identify the virus and cloud technology for running analysis process. We took a total of 62 samples data available on NCBI SRA database from 2 different BioProject datasets, 54 samples of SARS-CoV2 as case and 8 samples of Middle East Respiratory Syndrome Coronavirus (MERS-CoV) which has the similarity in Betacoronavirus genus level as control. We utilized Seven Bridges Cancer Genomic Cloud platform that implements metagenomics Centrifuge analysis workflow for simple, scalable, reproducible, rapid, cheap yet accurate SARS-CoV2 identification process. As the result, we had 99.99-100% of reads from the case and less than 0.04% of reads from control that classified into SARS-CoV2. It takes 13 minutes to run and costs $0.11 with Amazon Web Services r4.4xlarge spot instance.

description: Multi-photon emissions in laser sources represent a serious threat for the security of quantum key distribution (QKD). While the decoy-state technique allows to solve this problem, it requires uniform phase randomisation of the emitted pulses. However, gain-switched lasers operating at high repetition rates do not fully satisfy this requirement, as residual photons in the laser cavity introduce correlations between the phases of consecutive pulses. Here, we introduce experimental schemes to characterise the phase probability distribution of the emitted pulses, and demonstrate that an optimisation task over interferometric measures suffices in determining the impact of arbitrary order correlations, which ultimately establishes the security level of the implementation according to recent security proofs. We expect that our findings may find usages beyond QKD as well.

description: This paper is the outward manifestation of an interest desire that has been insistently tugging and prodding in the back of my mind ever since I first became. And my new part of public health work. Everyone I knew seemed so intent and busy with maternal and infant hygiene programs or school health work that there seemed to be very little done for the child in between. Just what happens to these in between children? What were the policies of the past in regard to this group? Has or is something being done to develop a part in public health work which has their interest in welfare at heart? These are some of the questions I set out to find answers for when I began this paper.

description: Deficiency and toxicity of micronutrient boron (B) play a critical role in plant productivity. In this study, the evaluation of B supplementation on biomass and essential oil (EO) yield of rose-scented geranium (Pelargonium graveolens L.) and its distribution at different application rates (2.5, 5.0, and 7.5 kg ha−1) was performed in a field trial during the growing season of two consecutive years 2017–18 and 2018–19. Boron uptake, plant biomass, and EO yield along with EO constituent in leaves were determined at different time scales. Application of B significantly improved the biomass yield of P. graveolens and at B-II treatment (5.0 kg ha−1 dose) highest biomass and EO yield was recorded, however, B-III treatment (7.5 kg ha−1) demonstrated toxicity symptoms like the decline in protein and chlorophyll content and an increase in proline and stress enzymes (SOD, CAT) in plant leaves. The effects of B on EO constituents varied with the different developmental stages of P. graveolens. Furthermore, the application of B at 5.0 kg ha−1 acts as a stimulant in upgrading the quality and quantity of EO with improved main aroma constituent’s P. graveolens than the control without modulating odor quality i.e., citronellol:geraniol (C:G) ratio. Hence, the study revealed a balanced level of B as a crucial parameter for the enhanced productivity with the improved economic return of P. graveolens.

This allow us to detect the presence of substituting impurities on graphene. The case of vacancies is also analyzed. We find that the shape and magnitude of the STM characteristic curves depend on the position of the tip and on the nature of the defect, with the strength of the binging between the impurity and the carbon atoms playing an important role. Also the nature of the last atom of the tip has an influence on the shape of the characteristic curve.

description: In this study, we explore the influence of quantum gravitational corrections, derived from Loop Quantum Gravity (LQG), on the efficiency of the magnetic Penrose process (MPP) in black hole (BH) environments. We begin by analyzing the rotating Loop Quantum Black Hole (LQBH) metric, describing the structure of the event horizon and ergosphere as functions of the quantum parameter $ε= γδ$, with $γ$ representing the Immirzi parameter and $δ$ the polymeric parameter, and the spin parameter $a$. These modifications provide a novel setting for exploring the dynamics of charged particles near the LQBH and evaluating the resultant energy extraction through the MPP. Interestingly, for a given value of the LQBH parameter $a$, we observe that the ergosphere region of the LQBH exhibits a more intricate structure compared to its classical counterpart, the Kerr BH, as $ε$ increases. Furthermore, we find that the overall efficiency of the process decreases with $ε$ that decreases $a_{max}$, again in contrast to the Kerr BH, where efficiency rises with an increasing $a$. Our analysis also extends to astrophysical contexts, applying constraints on the mass and magnetic field of LQBHs for astrophysical BH candidates, including SgrA*, M87*, NGC 1052, and BZ (Blandford and Znajek sources, i.e., supermassive BHs with masses around $10^9 M_\odot$ and magnetic fields in the range $10^3-10^4 \text{G}$). We assess these sources as potential accelerators of high-energy protons across different values of the quantum parameter $ε$. Additionally, we examine how variations in the magnetic field strength $B$ and quantum corrections impact the energy of protons accelerated from M87$^{\star}$ and Sgr A$^{\star}$ following beta decay.

description: We study the S=1 square lattice Heisenberg antiferromagnet with spatially anisotropic nearest neighbor couplings $J_{1x}$, $J_{1y}$ frustrated by a next-nearest neighbor coupling $J_{2}$ numerically using the density-matrix renormalization group (DMRG) method and analytically employing the Schwinger-Boson mean-field theory (SBMFT). Up to relatively strong values of the anisotropy, within both methods we find quantum fluctuations to stabilize the Néel ordered state above the classically stable region. Whereas SBMFT suggests a fluctuation-induced first order transition between the Néel state and a stripe antiferromagnet for $1/3\leq J_{1x}/J_{1y}\leq 1$ and an intermediate paramagnetic region opening only for very strong anisotropy, the DMRG results clearly demonstrate that the two magnetically ordered phases are separated by a quantum disordered region for all values of the anisotropy with the remarkable implication that the quantum paramagnetic phase of the spatially isotropic $J_{1}$-$J_{2}$ model is continuously connected to the limit of decoupled Haldane spin chains. Our findings indicate that for S=1 quantum fluctuations in strongly frustrated antiferromagnets are crucial and not correctly treated on the semiclassical level.

description: This study was developed to investigate if Ca and Mg silicate application as Si source combined with inoculation with Azospirillum brasilense and N rates can affect corn nutrient uptake. The study was set up in a Rhodic Hapludox under no-till system, located in Selvíria, state of Mato Grosso do Sul, Brazil. Treatments included: (i) two seed inoculation (with and without A. brasilense); (ii) two soil amendment sources (Ca and Mg silicate as Si source and dolomitic limestone); and (iii) five N application rates applied as side-dress (0 to 200 kg ha−1). Increasing N rates positively influenced corn nutrition with increased nutrient and Si uptake in shoot and grain. The average nutrient uptake in descending order was K > N > Ca > Si > Mg > S > P >Fe > Mn > Zn > Cu > B for shoot and N > K > P > S > Mg > Ca > Si> Fe > Zn > Mn > B > Cu for grain. Calcium and Mg silicate application positively influenced corn nutrition with greater shoot P, K, Ca, S, and B uptake and grain Ca uptake. Inoculation with A. brasilense was found to increase nutrient uptake with greater shoot N, K, Ca, B, and Si and grain Cu uptake. Grain N and S increased by 22.5 and 26.8% when plants were inoculated and 200 kg N ha−1 was applied and grain Zn increased by 88.6, 65.7, and 99% when plants were inoculated and 50, 150, and 200 kg N ha−1 were applied, respectively. Therefore, studies conducted under tropical conditions are needed to better understand the role of Si combined with PGPB inoculation under different N management and their effects on plant nutrition and cereal development aiming at improving nutrient replenishment.

description: Based on ab initio density-functional-theory using generalized gradient approximation, we systematically study the optical and electronic properties of the insulating dense sodium phase (Na-hp4) reported recently [Ma \textit{et al.}, Nature \textbf{458}, 182 (2009)]. The structure is found optically anisotropic and transparent to visible light, which can be well interpreted using its electronic band structure and angular moment decomposed density of states. Through the bader analysis of Na-hp4 at different pressures, we conclude that ionicity exists in the structure and becomes stronger with increasing pressure. In addition, the absorption spectra in the energy range from 1.4 to 2.4 eV are compared with recent experimental results and found good agreement. It is found that the deep-lying valence electrons participate in the interband transition.

description: Axions have long been considered plausible candidates for dark matter. The axion dark matter emitted from cosmic strings after the Peccei-Quinn (PQ) symmetry breaking in the early Universe was extensively simulated. In this work, we study dark matter and gravitational waves through the lattice simulation of the Axion-Higgs string. We gave the dark matter overproduction and the Big Bang nucleosynthesis bounds on the axion decay constant $f_a$ and the axion mass $m_a$ for axion-like particles, and found that the predicted gravitational wave spectra cannot be probed by the dataset of the current pulsar timing array experiments.

description: We run mean-field shearing-box numerical simulations with a temperature-dependent resistivity and compare them to a reduced dynamical model. Our simulations reveal the co-existence of two quasi-steady states, a `quiet' state and an `active' turbulent state, confirming the predictions of the reduced model. The initial conditions determine on which state the simulation ultimately settles. The active state is strongly influenced by the geometry of the computational box and the thermal properties of the gas. Cubic domains support permanent channel flows, bar-shaped domains exhibit eruptive behaviour, and horizontal slabs give rise to infrequent channels. Meanwhile, longer cooling time-scales lead to higher saturation amplitudes.

description: The article presents the results of a study of the unique sacrifice of the Levinsadovka sacrificial complex. On it were found large accumulations of animal bones near the buildings. An analogue of this sacrificial complex in the Northern Black Sea region not previously detected. Planigraphy of the sacrificial complex analyzed by arhaeoastronomical methods. The new method of calculating the terrain elevations with the use of topographic maps has been developed within this research to improve the accuracy. The location of bone clusters and the location of single finds of ancient stone tools were compared with the bearings of the rising and setting of the Sun and the Moon in the astronomically significant moments of the year. The orientation to important directions, associated with the Moon, in the organization of the sacrificial complex was identified as a result of this comparison. Detected orientation of the Levinsadovka sacrificial complex allows considering it the Moon sanctuary. Sacrificed fragments of stone tools with smooth surface were located on the Moon directions as did clusters of bones. Using folklore data it is concluded that the stone tools symbolized thunderstones, and were regarded as fragments of the stone Sky or the Moon in the Bronze Age, most likely.
Journey to the center of the common envelope evolution. Inner dynamics of the post-dynamical inspiral

description: Three-dimensional hydrodynamical simulations of common envelope evolution are often terminated soon after the initial dynamical plunge of the companion transitions into a long-lasting post-dynamical inspiral with slowly varying semi-major axis, $a_\text{b}$. This premature termination is often due to insufficient numerical resolution and challenges associated with the softening of the gravitational potential of the two cores. In this work, we use statically-refined 3D hydrodynamical simulations to study binaries orbiting inside a common envelope, exploring the effects of varying numerical resolution, $δ$, gravitational potential softening prescriptions, and the associated softening lengthscale, $ε$. We find that quantities such as the binary inspiral timescale or the volume-averaged shearing rate typically converge to asymptotic values only for $ε\le 0.1 a_\text{b}$ and $δ\le 6 \times 10^{-3}a_\text{b}$ with smaller $ε$ requiring correspondingly smaller $δ$. After a few tens of binary orbits, the two cores become surrounded by a corotating, nearly hydrostatic gas structure, resembling the shared envelope of a contact binary. We propose that this structure is responsible for the slowing down of the dynamical inspiral, leading to an asymptotic inspiral timescale of approximately $10^5$ orbital periods for a binary mass ratio $q=1/3$, and approximately $10^6$ orbital periods for a binary mass ratio $q=1$. By investigating kinetic helicity, we argue that the magnetic field is unlikely to organize into large-scale structures via the usual $α$--effect during the post-dynamical phase. Even in the absence of magnetic fields, we observe intermittent polar outflows collimated by partially centrifugally evacuated polar funnels. (abridged)

DTUrtle – Differential transcript usage analysis for bulk and single-cell data
Creators: name: Tekath, Tobias
name: Dugas, Martin
Publisher: name: F1000 Research Limited
Year: 2020

description: Motivation:
The rise of (single-cell) RNA-seq data collection in the recent years is unmatched. Commonly, this data is mostly used to determine differential gene expression (DGE) between samples or cell types. Utilizing transcriptomic quantifiers, the very same data sets can additionally be used for a transcript level analysis. Complementary to a DGE-analysis, proportional changes in the transcript composition of a gene would be of great interest for many research questions, such as analysis of differential splicing on bulk or single-cell level.

Results:
We present the easy-to-use R package DTUrtle that enables a broad audience to perform differential transcript usage (DTU) analysis. It is the first package that both supports counts from bulk and single-cell RNA-seq data, optionally utilizing a sparse data representation. DTUrtle builds upon established statistical frameworks for DTU analysis, offers customizable filtering schemes and a variety of visualization options. It has been successfully applied to single-cell and bulk RNA-seq data from both human and mouse.

Conclusion:
DTUrtle enables a comfortable way for researchers to perform DTU analysis of single-cell and bulk data and allows for an indepth inspection of the results via multiple visualization options. It could be able to establish DTU analysis as a complementary standard analysis for RNA-seq data.

Key features: DTU analysis in a few user-friendly steps Bulk and single-cell RNAseq data support Support and optimizations for sparse data representations Established frameworks DRIMSeq and stageR for statistical testing Highly customizable filtering schemes Multiple ways to aggregate and visualize the results Plethora of vignettes, covering different usage scenarios
