description: Climate change, and especially the unprecedented speed at which it is currently progressing,requires a fundamental change, transition and accelerated action on all levels and from allshareholders. In order to slow the climate crisis, vast CO2 reductions are necessary combinedwith clear policy and behavioral changes. The CO2 footprint counts among the most commonlyknown environmental indicators, aiding policy makers to evaluate and analyze progress andgiving a clear and understandable indication of the CO2 developments and trends.This thesis aims to analyze and draw conclusions from climate- and CO2 relevant policies ofthe USA and China, in order to understand which learnings can be applied to Europe. Policiesimpacting green innovation will be looked upon in detail, analyzing three drivers in bothcountries. The innovation criteria focused on were examined from a corporate andgovernmental perspective and centered around the country’s (a) Legal and RegulatoryFramework, (b) its Entrepreneurial Conditions and Requirements for Competitiveness and (c)its Financial and Tax System. Knowing the drivers and (past) impacts, it is the goal of this thesis to analyze their previouscontributions, possibly re-evaluate the criteria and effectiveness before questioning ways forthe European Union to use these learnings to foster green innovation within the EU in the nextyears. Although policy approaches cannot be implemented 1:1 in another country, it has beenfound that the hypotheses H1-H3 could be validated in the case of the US and China. Amongstothers, stricter environmental laws and regulations do generate the push-pull effect and aretherefore beneficial for corporate as well as governmental targets (H1). Strong, independentpatents are seen as key regarding entrepreneurial conditions, as they foster green innovation(H2), aid transparent communication and reduce inefficiency. Nonetheless, financial help (e.g.tax credit, ease of the investment landscape) needs to be given to SMEs and larger business(H3) in order to lift the potential additional financial burden coming with green adjustments.Partnerships between the public and private sector are essential to bridge possible investmentgaps and build a stronger civil society involvement. As there is no time to waste, hopefullythese policy examples and learnings can help multiple countries and especially the EU to implement and act faster, more efficiently and environmentally KPI-driven.

description: Let $Σ$ be a codimension one submanifold of an $n$-dimensional Riemannian manifold $M$, $n\geqslant 2$. We give a necessary condition for an isometric immersion of $Σ$ into $\mathbb R^q$ equipped with the standard Euclidean metric, $q\geqslant n+1$, to be locally isometrically $C^1$-extendable to $M$. Even if this condition is not met, "one-sided" isometric $C^1$-extensions may exist and turn out to satisfy a $C^0$-dense parametric $h$-principle in the sense of Gromov.

Is the recently proposed Mars-sized perturber at $65-80~\textrm{AU}$ ruled out by the Cassini ranging data?

description: Recently, the existence of a pointlike pertuber PX with $1~m_\textrm{Mars}\lesssim m_\textrm{X}\lesssim 2.4~m_\oplus$ supposedly moving at $65-80~\textrm{AU}$ along a moderately inclined orbit has been hypothesized in order to explain certain features of the midplane of the Kuiper Belt Objects (KBOs). We preliminarily selected two possible scenarios for such a PX, and numerically simulated its effect on the Earth-Saturn range $ρ(t)$ by varying some of its orbital parameters over a certain time span; then, we compared our results with some existing actual range residuals. By assuming $m_\textrm{X} = 1~m_\textrm{Mars}$ and a circular orbit, such a putative new member of our Solar System would nominally perturb $ρ(t)$ by a few km over $Δt = 12~\textrm{yr}~(2004-2016)$. However, the Cassini spaceraft accurately measured $ρ(t)$ to the level of $σ_ρ\simeq 100~\textrm{m}$. Nonetheless, such a scenario should not be considered as necessarily ruled out since the Cassini data were reduced so far without explicitly modeling any PX. Indeed, a NASA JPL team recently demonstrated that an extra-signature as large as 4 km affecting the Kronian range would be almost completely absorbed in fitting incomplete dynamical models, i.e. without PX itself, to such simulated data, thus not showing up in the standard post-fit range residuals. Larger anomalous signatures would instead occur for $m_\textrm{X} > 1~m_\textrm{Mars}$. Their nominal} amplitude could be as large as $50-150~\textrm{km}$ for $m_\textrm{X} = 2.4~m_\oplus$, thus making less plausible their existence.

description: We study some structural properties of Construction-A lattices obtained from low density parity check (LDPC) codes over prime fields. Such lattices are called low density Construction-A (LDA) lattices, and permit low-complexity belief propagation decoding for transmission over Gaussian channels. It has been shown that LDA lattices achieve the capacity of the power constrained additive white Gaussian noise (AWGN) channel with closest lattice-point decoding, and simulations suggested that they perform well under belief propagation decoding. We continue this line of work, and prove that these lattices are good for packing and mean squared error (MSE) quantization, and that their duals are good for packing. With this, we can conclude that codes constructed using nested LDA lattices can achieve the capacity of the power constrained AWGN channel, the capacity of the dirty paper channel, the rates guaranteed by the compute-and-forward protocol, and the best known rates for bidirectional relaying with perfect secrecy.

description: Das Diskussionspapier „Ackerbaustrategie 2035 – Perspektiven für einen produktiven und vielfältigen Pflanzenbau“ des BMEL zeigt anhand von sechs Leitlinien und zwölf dazugehörigen Handlungsfeldern Optionen für die Verbesserung des deutschen Ackerbaus auf. Es enthält viele sinnvolle Ansätze. Allerdings greift das Papier bezüglich des Erhalts und der Förderung der Biodiversität in der deutschen Landwirtschaft zu kurz. Der WBBGR formuliert und erläutert daher 10 Empfehlungen für eine ganzheitliche Betrachtung von landwirtschaftlicher Produktion und biologischer Vielfalt sowie für die Förderung der Biodiversität in der Agrarlandschaft: 1. Biodiversität in der Landwirtschaft mit Zielbildern und zügig umzusetzenden Maßnahmen ganzheitlich betrachten 2. Mehr biodiversitätsfördernde Ziele konkret hinsichtlich Inhalt und Umfang sowie Zeitraum benennen sowie den Grad der Zielerreichung zu späteren Zeitpunkten messbar machen 3. Biodiversität beeinträchtigende Zielkonflikte der Maßnahmen benennen und Lösungsvorschläge entwickeln 4. Mehr biodiversitätsfördernde Maßnahmen ausgestalten 5. Inhaltliche und zeitliche Umsetzung biodiversitätsfördernder Maßnahmen präzisieren 6. Klares Bekenntnis zu mehr Fördermitteln für Gemeinwohlleistungen (durch den Ackerbau) bei der zukünftigen GAP abgeben 7. Inwertsetzung von Biodiversität und Ökosystemleistungen fördernden Maßnahmen der Landwirte1 über den Markt vorantreiben 8. Ressort- und strategieübergreifende Ziele und Maßnahmen identifizieren sowie Zuständigkeiten frühzeitig abstimmen und festlegen 9. Mehr Weiterbildungsmaßnahmen zur Biodiversitätsförderung für alle an der Aus- und Weiterbildung von Landwirten beteiligten Personen verpflichtend machen 10. Forschungsaktivitäten zur Biodiversität verstärken und Innovationen fördern. Biodiversität und eine ebenso effiziente wie effektive landwirtschaftliche Produktion sollten bei der Umsetzung der Ackerbaustrategie nicht als Gegensätze („Produktion oder Biodiversität“), sondern als Teile eines sich gegenseitig fördernden Systems („Produktion und Biodiversität“) behandelt werden.

We show that the Schwinger formula for charged particle pair production is reproduced exactly by the semiclassical expansion around classical instanton solutions when the leading order of fluctuations is taken into account. We prove that all corrections to this leading approximation vanish and that the WKB approximation to the world line path integral is exact.

title: Los Angeles Soft Story Retrofit Benefits and Costs
Creators: name: Porter, Keith Alan
Publisher: name: University of Colorado Boulder
Year: 2023

description:         California has several seismically dangerous building types, but soft-story woodframe buildings are so numerous and vulnerable that San Francisco, Los Angeles, Oakland, and other cities have taken the unusual step of requiring that they be strengthened to better resist earthquakes 1,2,3,4. Los Angeles’ retrofit ordinance has led to 8,100 soft-story apartment buildings being retrofitted, protecting 117,000 housing units 5. Recent estimates suggest that adding ground-story shearwalls, steel frames, or both to strengthen the buildings costs between $80,000 and $160,000 per building in today’s dollars, or about $11,000 per housing unit 6. That implies that Los Angeles property owners have spent about $1.3 billion to retrofit these buildings. How much benefit will that investment produce, in reduced future earthquake losses?

        We answered that question using analyses from Natural Hazard Mitigation Saves 7, the most exhaustive benefit-cost analysis of natural-hazard mitigation ever performed. It included a study of retrofitting soft-story conditions in multifamily woodframe housing. It used FEMA’s estimates of where such buildings exist, how many people live in them, and how many occupy them at various times of day 8. It used the US Geological Survey’s estimates of how frequently and strongly earthquakes shake them 9. And it employed models of probabilistic damage given various levels of shaking 10,11. It calculated costs and benefits on a census-tract level and presented them at the county level. We scaled the Los Angeles County results to account for the 117,000 housing units retrofitted to comply with Resilience by Design. Here is what we found.

        Los Angeles’ soft-story retrofits will avoid an estimated 1,500 deaths and 27,000 nonfatal injuries and cases of post-traumatic stress disorder. The retrofits will prevent the partial, temporary, or permanent loss of 65,000 housing units, home to 170,000 people. They will reduce future losses by $41 billion in property damage, life-safety impacts, and other economic consequences. See Table 1 and Table 2. The benefits divided by the costs, called the benefit-cost ratio, is 32 to 1, meaning $32 saved per $1 of up-front cost, a very cost-effective investment. For comparison, President Biden convinced Congress to pass the $1.3 trillion infrastructure bill partly by citing the Mitigation Saves estimate of the 6 to 1 benefit-cost ratio for strengthening public-sector infrastructure.
Phylogeny estimation given sequence length heterogeneity

Publisher: name: Zenodo
Year: 2023

description: Abstract Phylogeny estimation is a major step in many biological studies, and has many well known challenges. With the dropping cost of sequencing technologies, biologists now have increasingly large datasets available for use in phylogeny estimation. Here we address the challenge of estimating a tree given large datasets with a combination of full-length sequences and fragmentary sequences, which can arise due to a variety of reasons, including sample collection, sequencing technologies, and analytical pipelines. We compare two basic approaches: (1) computing an alignment on the full dataset and then computing a maximum likelihood tree on the alignment, or (2) constructing an alignment and tree on the full length sequences and then using phylogenetic placement to add the remaining sequences (which will generally be fragmentary) into the tree. We explore these two approaches on a range of simulated datasets, each with 1000 sequences and varying in rates of evolution, and two biological datasets. Our study shows some striking performance differences between methods, especially when there is substantial sequence length heterogeneity and high rates of evolution. We find in particular that using UPP to align sequences and RAxML to compute a tree on the alignment provides the best accuracy, substantially outperforming trees computed using phylogenetic placement methods. We also find that FastTree has poor accuracy on alignments containing fragmentary sequences. Overall, our study provides insights into the literature comparing different methods and pipelines for phylogenetic estimation, and suggests directions for future method development.

description: We use tropical and nonarchimedean geometry to study the moduli space of genus $0$ stable maps to $\mathbb{P}^1$ relative to two points. This space is exhibited as a tropical compactification in a toric variety. Moreover, the fan of this toric variety may be interpreted as a moduli space for tropical relative stable maps with the same discrete data. As a consequence, we confirm an expectation of Bertram and the first two authors, that the tropical Hurwitz cycles are tropicalizations of classical Hurwitz cycles. As a second application, we obtain a full descendant correspondence for genus $0$ relative invariants of $\mathbb{P}^1$.

description: Water exists as two nuclear-spin isomers, para and ortho, determined by the overall spin of its two hydrogen nuclei. For isolated water molecules the conversion between these isomers is forbidden and they act as different molecular species. Yet, these species are not readily separable, and little is known about their specific physical and chemical properties, conversion mechanisms, or interactions. Here we demonstrate the production of isolated samples of both spin isomers in pure beams of para and ortho water, with both species in their respective absolute ground state. These single-quantum-state samples are ideal targets for unraveling spin-conversion mechanisms, for precision spectroscopy and fundamental-symmetry-breaking studies, and for spin-enhanced applications, e. g., laboratory astrophysics and -chemistry or hypersensitized NMR experiments.
Variational principles for self-adjoint operator functions arising from second-order systems

description: Variational principles are proved for self-adjoint operator functions arising from variational evolution equations of the form \[ \langle\ddot{z}(t),y \rangle + \mathfrak{d}[\dot{z} (t), y] + \mathfrak{a}_0 [z(t),y] = 0. \] Here $\mathfrak{a}_0$ and $\mathfrak{d}$ are densely defined, symmetric and positive sesquilinear forms on a Hilbert space $H$. We associate with the variational evolution equation an equivalent Cauchy problem corresponding to a block operator matrix $\mathcal{A}$, the forms \[ \mathfrak{t}(λ)[x,y] := λ^2\langle x,y\rangle + λ\mathfrak{d}[x,y] + \mathfrak{a}_0[x,y], \] where $λ\in \mathbb C$ and $x,y$ are in the domain of the form $\mathfrak{a}_0$, and a corresponding operator family $T(λ)$. Using form methods we define a generalized Rayleigh functional and characterize the eigenvalues above the essential spectrum of $\mathcal{A}$ by a min-max and a max-min variational principle. The obtained results are illustrated with a damped beam equation.

Optimized recentered confidence spheres for the multivariate normal mean

Year: 2014

description: Casella and Hwang, 1983, JASA, introduced a broad class of recentered confidence spheres for the mean $\boldsymbolθ$ of a multivariate normal distribution with covariance matrix $σ^2 \boldsymbol{I}$, for $σ^2$ known. Both the center and radius functions of these confidence spheres are flexible functions of the data. For the particular case of confidence spheres centered on the positive-part James-Stein estimator and with radius determined by empirical Bayes considerations, they show numerically that these confidence spheres have the desired minimum coverage probability $1-α$ and dominate the usual confidence sphere in terms of scaled volume. We shift the focus from the scaled volume to the scaled expected volume of the recentered confidence sphere. Since both the coverage probability and the scaled expected volume are functions of the Euclidean norm of $\boldsymbolθ$, it is feasible to optimize the performance of the recentered confidence sphere by numerically computing both the center and radius functions so as to optimize some clearly specified criterion. We suppose that we have uncertain prior information that $\boldsymbolθ= \boldsymbol{0}$. This motivates us to determine the center and radius functions of the confidence sphere by numerical minimization of the scaled expected volume of the confidence sphere at $\boldsymbolθ= \boldsymbol{0}$, subject to the constraints that (a) the coverage probability never falls below $1-α$ and (b) the radius never exceeds the radius of the standard $1-α$ confidence sphere. Our results show that, by focusing on this clearly specified criterion, significant gains in performance (in terms of this criterion) can be achieved. We also present analogous results for the much more difficult case that $σ^2$ is unknown.

description: This article investigates structural, geometrical, and topological characterizations and properties of weakly modular graphs and of cell complexes derived from them. The unifying themes of our investigation are various `nonpositive curvature' and `local-to-global' properties and characterizations of weakly modular graphs and their subclasses. Weakly modular graphs have been introduced as a far-reaching common generalization of median graphs (and more generally, of modular and orientable modular graphs), Helly graphs, bridged graphs, and dual polar graphs occurring under different disguises in several seemingly-unrelated fields of mathematics: Metric graph theory, Geometric group theory, Incidence geometries and buildings, Theoretical computer science and combinatorial optimization. We give a local-to-global characterization of weakly modular graphs and their subclasses in terms of simple connectedness of associated triangle-square complexes and specific local combinatorial conditions. In particular, we revisit characterizations of dual polar graphs by Cameron and by Brouwer-Cohen. We also show that (disk-)Helly graphs are precisely the clique-Helly graphs with simply connected clique complexes. With $l_1$-embeddable weakly modular and sweakly modular graphs we associate high-dimensional cell complexes, having several strong topological and geometrical properties (contractibility and the CAT(0) property). Their cells have a specific structure: they are basis polyhedra of even $\triangle$-matroids in the first case and orthoscheme complexes of gated dual polar subgraphs in the second case. We resolve some open problems concerning subclasses of weakly modular graphs: we prove a Brady-McCammond conjecture about CAT(0) metric on the orthoscheme complexes of modular lattices; we answer Chastand's question about prime graphs for pre-median graphs.

description: Analysis of the driving Factors behind a Movie:

Movies are loved all over the world, however, there is no particular way to predict a movie’s outcome. The paper proposes an engineered approach to predict whether a movie would be successful based on the features like the genre, cast, production company using data provided in the movie dataset from Kaggle. This analysis aims to identify the impact of the choices made during the production of a film. These choices can be picking the Director, Actors, Release Date, Genre, Language of the film, Viewer Rating etc. In particular, the aim is to understand the popularity rating of a film and identify relationships between the budget, cast, and rating of the film. From the analysis, an exploratory study of the impact that these features have on the popularity of a movie will be carried out and the choices that drive the commercial success of a movie will be sought.

The conversation begins discussing the need for English language teachers at the school. As more members enter the conversation, the discussion begins to include the other subjects being taught and the lack of faculty and time. Music, biology, and language teaching responsibilities are split among the members, often times getting in the way of individual leisure, endeavors, and responsibilities. This discussion of overwork and full schedules leads to a discussion on the number of students at the school, as members suggests dividing the Kindergarten school as well as combining classes into single classrooms. The members are reassured by their understanding that teaching is a service to the country, and efforts to hire new teachers in order to maintain religious education are agreed upon.

description: The eigenstates of a quantum spin glass Hamiltonian with long-range interaction are examined from the point of view of localisation and entanglement. In particular, low particle sectors are examined and an anomalous family of eigenstates is found that is more delocalised but also has larger inter-spin entanglement. These are then identified as particle-added eigenstates from the one-particle sector. This motivates the introduction and the study of random promoted two-particle states, and it is shown that they may have large delocalisation such as generic ran- dom states and scale exactly like them. However, the entanglement as measured by two-spin concurrence displays different scaling with the total number of spins. This shows how for different classes of complex quantum states entanglement can be qualitatively different even if localisation measures such as participation ratio are not.

We show that the prices are stable under the demand process and derive their analytic expansions for small risk aversion coefficients of the dealer.

description: The paper concerns area preserving homeomorphisms of surfaces that are isotopic to the identity. The purpose of the paper is to find a maximal identity isotopy such that we can give a fine descriptions of the dynamics of its transverse foliation. We will define a kind of identity isotopies: torsion-low isotopies. In particular, when $f$ is a diffeomorphism with finitely many fixed points such that every fixed point is not degenerate, an identity isotopy $I$ of $f$ is torsion-low if and only if for every point $z$ fixed along the isotopy, the (real) rotation number $ρ(I,z)$, which is well defined when one blows-up $f$ at $z$, is contained in $(-1,1)$. We will prove the existence of torsion-low maximal identity isotopies, and we will deduce the local dynamics of the transverse foliations of any torsion-low maximal isotopy near any isolated singularity.

General Navier-Stokes-like Momentum and Mass-Energy Equations

Subjects: subject: Classical Physics (physics.class-ph)

description: A new system of general Navier-Stokes-like equations is proposed to model electromagnetic analogous to hydrodynamic. While most attempts to derive analogues of hydrodynamic to electromagnetic, and vice-versa, start with Navier-Stokes or a Euler approximation, we propose general conservation equations as a starting point. Such equations provide a structured framework from which additional insights into the problem at hand could be obtained. To that end, we propose a system of momentum and mass-energy conservation equations coupled through both momentum density and velocity vectors.

description: We argue that an anisotropic dipolar imaginary primordial power spectrum is possible within the framework of noncommutative space-times. We show that such a spectrum provides a good description of the observed dipole modulation in CMBR data. We extract the corresponding power spectrum from data. The dipole modulation is related to the observed hemispherical anisotropy in CMBR data, which might represent the first signature of quantum gravity.

Subjects: preprints, peer-review, submission by authors, recommendation platform

description: The “Peer Community in” (PCI) is a non-profit scientific organization that aims to create specific communities of researchers reviewing and recommending, for free, unpublished preprints in their field (i.e. unpublished articles deposited on open online archives like arXiv.org and bioRxiv.org). Recommended preprints are then valid, final and citable article. These specific communities are entitled Peer Community in X, e.g. Peer Community in Evolutionary Biology (PCI Evol Biol), Peer Community in Ecology (PCI Ecol), Peer Community in Paleontology (PCI Paleo) etc ... Once recommended by one or several of these PCIs on the basis of rigorous peer reviews, preprints become valid references and may be considered to be articles of high value. Recommended preprints can be used by scientists and cited in the scientific literature. There is no need for these recommended preprints to be submitted for publication in classic journals (although they can be, according to the authors’ preferences). Authors can then leave their recommended article as a recommended preprint in a preprint server, or transfer it directly for publication in the the diamond open-access Peer Community Journal or submit it to one of the PCI-friendly journals or to any other journals accepting submissions of preprints.

description: We present a method for generating precise magnetic potentials that can be described by a polynomial series along the axis of a cold atom waveguide near the surface of an atom chip. With a single chip design consisting of several wire pairs, various axial potentials can be created by varying the ratio of the currents in the wires, including double wells, triple wells, and pure harmonic traps with suppression of higher order terms. We use this method to design and fabricate a chip with modest experimental requirements. Finally, we use the chip to demonstrate a double well potential.

description: We study up to second order the galaxy number over-density that depends on magnification in redshift space on cosmological scales for a concordance model. The result contains all general relativistic effects up to second order which arise from observing on the past light cone, including all redshift and lensing distortions, contributions from velocities, Sachs-Wolfe, integrated SW and time-delay terms. We find several new terms and contributions that could be potentially important for an accurate calculation of the bias on estimates of non-Gaussianity and on precision parameter estimates.

description: In this paper a macroscopic quantum oscillator is introduced that consists of a flux qubit in the form of a cantilever. The magnetic flux linked to the flux qubit and the mechanical degrees of freedom of the cantilever are naturally coupled. The coupling is controlled through an external magnetic field. The ground state of the introduced flux-qubit-cantilever corresponds to a quantum entanglement between magnetic flux and the cantilever displacement.

Achieving New Upper Bounds for the Hypergraph Duality Problem through Logic

description: The hypergraph duality problem DUAL is defined as follows: given two simple hypergraphs $\mathcal{G}$ and $\mathcal{H}$, decide whether $\mathcal{H}$ consists precisely of all minimal transversals of $\mathcal{G}$ (in which case we say that $\mathcal{G}$ is the dual of $\mathcal{H}$). This problem is equivalent to deciding whether two given non-redundant monotone DNFs are dual. It is known that non-DUAL, the complementary problem to DUAL, is in $\mathrm{GC}(\log^2 n,\mathrm{PTIME})$, where $\mathrm{GC}(f(n),\mathcal{C})$ denotes the complexity class of all problems that after a nondeterministic guess of $O(f(n))$ bits can be decided (checked) within complexity class $\mathcal{C}$. It was conjectured that non-DUAL is in $\mathrm{GC}(\log^2 n,\mathrm{LOGSPACE})$. In this paper we prove this conjecture and actually place the non-DUAL problem into the complexity class $\mathrm{GC}(\log^2 n,\mathrm{TC}^0)$ which is a subclass of $\mathrm{GC}(\log^2 n,\mathrm{LOGSPACE})$. We here refer to the logtime-uniform version of $\mathrm{TC}^0$, which corresponds to $\mathrm{FO(COUNT)}$, i.e., first order logic augmented by counting quantifiers. We achieve the latter bound in two steps. First, based on existing problem decomposition methods, we develop a new nondeterministic algorithm for non-DUAL that requires to guess $O(\log^2 n)$ bits. We then proceed by a logical analysis of this algorithm, allowing us to formulate its deterministic part in $\mathrm{FO(COUNT)}$. From this result, by the well known inclusion $\mathrm{TC}^0\subseteq\mathrm{LOGSPACE}$, it follows that DUAL belongs also to $\mathrm{DSPACE}[\log^2 n]$. Finally, by exploiting the principles on which the proposed nondeterministic algorithm is based, we devise a deterministic algorithm that, given two hypergraphs $\mathcal{G}$ and $\mathcal{H}$, computes in quadratic logspace a transversal of $\mathcal{G}$ missing in $\mathcal{H}$.

description: (An updated version of this manuscript has been accepted to Scientific Reports in 2016, please refer to http://www.nature.com/articles/srep31900) The highly anticipated transition from next generation sequencing (NGS) to third generation sequencing (3GS) has been difficult primarily due to high error rates and excessive sequencing cost. The high error rates make the assembly of long erroneous reads of large genomes challenging because existing software solutions are often overwhelmed by error correction tasks. Here we report a hybrid assembly approach that simultaneously utilizes NGS and 3GS data to address both issues. We gain advantages from three general and basic design principles: (i) Compact representation of the long reads lead to efficient alignments. (ii) Base-level errors can be skipped; structural errors need to be detected and corrected. (iii) Structurally correct 3GS reads are assembled and polished. In our implementation, preassembled NGS contigs are used to derive the compact representation of the long reads, which established an algorithmic conversion from a de Bruijn graph to an overlap graph, the two major assembly paradigms. Moreover, since NGS and 3GS data can compensate each other, our hybrid assembly approach reduces both of their sequencing requirements. Experiments show that our software is able to assemble mammalian-sized genomes orders of magnitude more efficiently in time than existing methods, while saving about half of the sequencing cost.
