description: The Qinghai-Tibet Plateau, with its high elevation and extreme climate, is a transport artery for a crude oil-importation pipeline in China. However, limited information is available regarding the effect of petroleum hydrocarbon (PH) contamination on soil bacterial diversity. Variations in the bacterial structure and composition after PH pollution were investigated by a combination of artificial simulated pollution and high-throughput DNA sequencing. The results demonstrated that the biodiversity of engine oil-contaminated soil samples was higher than that of diesel oil-contaminated soil samples, and 7 genera were identified from indigenous bacteria as potential oil degraders, including Sulfuritalea, Sphingomonas, Alkanindiges, Rhodococcus, Nocardioides, Rhodoplanes, and Actinobacteria_norank. We present a detailed profile of soil bacteria succession under different oil-pollution conditions, which may help in future studies of in-situ bioremediation in this region.

description: Dada O., Jack S. and George M. University–business engagement franchising and geographic distance: a case study of a business leadership programme, Regional Studies. This paper adapts a franchising perspective to generate a better understanding of geographic distance in university–business engagement. The study utilized an in-depth case study of a leadership and management development intervention, a programme specifically designed for small and medium-sized enterprise (SME) owner-managers (or directors) by the Institute for Entrepreneurship and Enterprise Development, within a well-respected institution, ranked in the top 1% of universities in the world. Unlike most studies, the research findings indicate that knowledge spillovers from university–business engagement can occur through replication in regions external to the university's locality.

description: In this paper, we show that the maximum number of points in $d\geq3$ dimensions determining exactly 2 distinct triangles is $2d$. We further show that this maximum is uniquely achieved by the vertices of the $d$-orthoplex. We build upon the work of Hirasaka and Shinohara who determined that the $d$-orthoplex is such an optimal configuration, but did not prove its uniqueness. Further, we present a more elementary argument for its optimality.

description: Carvalho R. and Silveira Neto R. Physical and human capital and Brazilian regional growth: a spatial econometric approach for the period 1970–2010, Regional Studies. This paper identifies the determinants of economic growth and analyses the dynamics of income using a panel of 522 Brazilian micro-regions for period 1970–2010. Based on the spatial extension of the Mankiw–Romer–Weil (MRW) model and explicitly considering both physical and human capital, the parameters of a Spatial Durbin Model (SDM) with fixed-effects are estimated. The direct and indirect impacts of the determinants of regional growth are then calculated. The results indicate strong spatial dependence among Brazilian micro-regions and that investments in both physical and human capital are important for the growth of the Brazilian regional economies.

description: In nonlife insurance, insurers use experience rating to adjust premiums to reflect policyholders’ previous claim experience. Performing prospective experience rating can be challenging when the claim distribution is complex. For instance, insurance claims are semicontinuous in that a fraction of zeros is often associated with an otherwise positive continuous outcome from a right-skewed and long-tailed distribution. Practitioners use credibility premium that is a special form of the shrinkage estimator in the longitudinal data framework. However, the linear predictor is not informative especially when the outcome follows a mixed distribution. In this article, we introduce a mixed vine pair copula construction framework for modeling semicontinuous longitudinal claims. In the proposed framework, a two-component mixture regression is employed to accommodate the zero inflation and thick tails in the claim distribution. The temporal dependence among repeated observations is modeled using a sequence of bivariate conditional copulas based on a mixed D-vine. We emphasize that the resulting predictive distribution allows insurers to incorporate past experience into future premiums in a nonlinear fashion and the classic linear predictor can be viewed as a nested case. In the application, we examine a unique claims dataset of government property insurance from the state of Wisconsin. Due to the discrepancies between the claim and premium distributions, we employ an ordered Lorenz curve to evaluate the predictive performance. We show that the proposed approach offers substantial opportunities for separating risks and identifying profitable business when compared with alternative experience rating methods.

This number extends the definition of $F$-threshold of a pair of ideals $I$ and $J$, $c^J(I)$ to a sequence of ideals $J$, $I_1, \ldots, I_t$. We obtain several properties that emulate those of the $F$-threshold. In particular, the $F$-volume detects $F$-pure complete intersections. In addition, we relate this invariant to the Hilbert-Kunz multiplicity.

description: Nathan Rosen's quantization approach to the gravitational collapse is applied in the simple case of a pressureless "star of dust" by finding the gravitational potential, the Schrodinger equation and the solution for the collapse's energy levels. By applying the constraints for a Schwarzschild black hole (BH) and by using the concept of BH effective state, previously introduced by one of the authors (CC), the BH quantum gravitational potential, Schrodinger equation and the BH energy spectrum are found. Remarkably, such an energy spectrum is in agreement (in its absolute value) with the one which was conjectured by Bekenstein in 1974 and consistent with other ones in the literature. This approach also permits to find an interesting quantum representation of the Schwarzschild BH ground state at the Planck scale. Moreover, two fundamental issues about BH quantum physics are addressed by this model: the area quantization and the singularity resolution. As regards the former, a result similar to the one obtained by Bekenstein, but with a different coefficient, has been found. About the latter, it is shown that the traditional classical singularity in the core of the Schwarzschild BH is replaced, in a full quantum treatment, by a two-particle system where the two components strongly interact with each other via a quantum gravitational potential. The two-particle system seems to be non-singular from the quantum point of view and is analogous to the hydrogen atom because it consists of a "nucleus" and an "electron".

description: Michalek J., Ciaian P. and Kancs d’A. Investment crowding out: firm-level evidence from Northern Germany, Regional Studies. The main objective of this paper is to estimate the extent to which firm investment is substituted (crowded out) by investment support policies granted under the European Union Rural Development Programme (RDP). The empirical analyses employed the difference-in-difference propensity score-matching approach, which allows several important sources of bias to be addressed, such as selection bias, simultaneity bias and functional form misspecification, from which many previous studies suffer. Using panel data of 1333 firms from the Schleswig-Holstein region in Germany, it is found that the crowding-out effect of the RDP is close to 100%, implying that firms use public support to substitute for private investments. Furthermore, no evidence was found that, due to the RDP programme support, firms would have brought forward their investments planned originally for a later period, rejecting the inter-temporal substitution of investments.
Not so presto? Outcomes of sluggish prestin in outer hair cells

description: Prestin (SLC26A5), a protein essential for the sensitivity of the mammalian ear, was so named from \emph{presto}. The assumption was that this membrane protein supports fast movement of outer hair cells (OHCs) that matches the mammalian hearing range, up to 20 kHz in general and beyond, depending on the species. \emph{In vitro} data from isolated OHCs appeared to be consistent with such frequencies. However, some recent reports cast doubts on this assumption, suggesting that the intrinsic transition rates of this protein are much lower, about 3 kHz for guinea pigs, not covering the auditory frequency range of the animal. Recent \emph{in vivo} data also show that the amplitude of OHC motion rolls off well below the best frequency of the location. The present report examines whether or not these resent observations are compatible with the physiological function of OHCs by using simple piezoelectric models.

description: Planar arrays of tree diagrams were introduced as a generalization of Feynman diagrams that enables the computation biadjoint amplitudes $m^{(k)}_n$ for $k>2$ . In this follow-up work we investigate the poles of $m^{(k)}_n$ from the perspective of such arrays. For general $k$ we characterize the underlying polytope as a Flag Complex and propose a computation of the amplitude based solely on the knowledge of poles, which number is drastically less than the number of full arrays. As an example we first provide all the poles for the cases $(k,n)=(3,7),(3,8),(4,8)$ and $(4,9)$ in terms of their generalized Feynman diagrams. We then implement a simple compatibility criteria together with an addition operation between arrays, and recover the full collections/arrays recently presented for such cases. Along the way we implement hard and soft kinematical limits, which provide a map between poles in kinematic space and their combinatoric arrays. We use the operation to give a proof of a previously conjectured combinatorial duality for arrays in $(k,n)$ and $(n-k,n)$. We also outline the relation to boundary maps of the hypersimplex $Δ_{k,n}$ and rays in the tropical Grassmannian $\textrm{Tr}(k,n)$.
description: comment: v2: 21 pages, 2 figures, 2 tables, references added, missing ancillary files in the Dropbox link are recovered. Planar arrays of Feynman diagrams for (k,n)=(4,9) are reconstructed just from their poles while those for (3,10) are predicted for the first time

description: In this paper we determine the topology of the moduli space $\mathcal{MS}_{1,1}(\vartheta)$ of surfaces of genus one with a Riemannian metric of constant curvature $1$ and one conical point of angle $2π\vartheta$. In particular, for $\vartheta\in (2m-1,2m+1)$ non-odd, $\mathcal{MS}_{1,1}(\vartheta)$ is connected, has orbifold Euler characteristic $-m^2/12$, and its topology depends on the integer $m>0$ only. For $\vartheta=2m+1$ odd, $\mathcal{MS}_{1,1}(2m+1)$ has $\lceil{m(m+1)/6}\rceil$ connected components. For $\vartheta=2m$ even, $\mathcal{MS}_{1,1}(2m)$ has a natural complex structure and it is biholomorphic to $\mathbb{H}^2/G_m$ for a certain subgroup $G_m$ of $\mathrm{SL}(2,\mathbb{Z})$ of index $m^2$, which is non-normal for $m>1$.

Causal relationship between asset prices and output in the United States: evidence from the state-level panel Granger causality test, Regional Studies. This paper investigates the causal relationship between asset prices and output across US states using a bootstrap panel Granger causality approach which allows not only for heterogeneity and cross-sectional dependence to be accounted for but also interdependency between asset markets. Empirical results from a trivariate vector autoregression (VAR) comprising real house prices, real stock prices and real per capita personal income over 1975–2012 reveal the existence of a unidirectional causality running from both asset prices to output. This confirms the leading indicator property of asset prices for the real economy, while also substantiating the wealth and/or collateral transmission mechanism.

description: The aim of this paper is to solve numerically, using the meshless method via radial basis functions, time-space-fractional partial differential equations of type Black-Scholes. The time-fractional partial differential equation appears in several diffusion problems used in physics and engineering applications, and models subdiffusive and superdiffusive behavior of the prices at the stock market. This work shows the flexibility of the radial basis function scheme to solve multidimensional problems with several types of nodes and it also shows how to reduce the condition number of the matrices involved.

description: We investigate what information on the orbit type stratification of a torus action on a compact space is contained in its rational equivariant cohomology algebra. Regarding the (labelled) poset structure of the stratification we show that equivariant cohomology encodes the subposet of ramified elements. For equivariantly formal actions, we also examine what cohomological information of the stratification is encoded. In the smooth setting we show that under certain conditions -- which in particular hold for a compact orientable manifold with discrete fixed point set -- the equivariant cohomologies of the strata are encoded in the equivariant cohomology of the manifold.

description: C-Met plays a crucial role in the development and progression of neoplastic disease. Type II c-Met inhibitors recognise the inactive DFG-out conformation of the kinase, result in better anti-tumour effects due to synergistic effect against the other kinases. According to our previous works, an (E)-N'-benzylidene group was selected as the initial fragment. Two series of (E)-N'-benzylidene hydrazides were designed by fragment growth method. The inhibitory activities were in vitro investigated against c-Met and VEGFR-2. Compound 10b exhibited the most potent inhibitory activity against the c-Met inhibitor (IC50 = 0.37 nM). Compound 11b exhibited multi-target c-Met kinase inhibitory activity as a potential type II c-Met inhibitor (IC50 = 3.41 nM against c-Met; 25.34 nM against VEGFR-2). The two compounds also demonstrate the feasibility of fragment-based virtual screening method for drug discovery.
On Codes for the Noisy Substring Channel

Year: 2021

description: We consider the problem of coding for the substring channel, in which information strings are observed only through their (multisets of) substrings. Due to existing DNA sequencing techniques and applications in DNA-based storage systems, interest in this channel has renewed in recent years. In contrast to existing literature, we consider a noisy channel model where information is subject to noise before its substrings are sampled, motivated by in-vivo storage. We study two separate noise models, substitutions or deletions. In both cases, we examine families of codes which may be utilized for error-correction and present combinatorial bounds on their sizes. Through a generalization of the concept of repeat-free strings, we show that the added required redundancy due to this imperfect observation assumption is sublinear, either when the fraction of errors in the observed substring length is sufficiently small, or when that length is sufficiently long. This suggests that no asymptotic cost in rate is incurred by this channel model in these cases. Moreover, we develop an efficient encoder for such constrained strings in some cases. Finally, we show how a similar encoder can be used to avoid formation of secondary-structures in coded DNA strands, even when accounting for imperfect structures.

description: Drucker J. Reconsidering the regional economic development impacts of higher education institutions in the United States, Regional Studies. This study models relationships between US higher education activities and regional economic performance, 2001–11. Advances include incorporating all degree-granting institutions; estimating spatial spillovers; and comparing multiple economic outcomes, including production and entrepreneurship. Higher education impacts vary by outcome measure but are less influential than in previous studies. Spillovers are substantial up to 60 miles (97 kilometres), reflecting considerable influence across space. More advanced degrees, science and engineering education, and population educational attainment are positively associated with entrepreneurial activity. These findings encourage the traditional university missions of research and teaching, and general policies promoting entrepreneurship, to support economic performance.

Néanmoins, il a conservé ces données et elles sont potentiellement très utile dans le cadre de Studium, comme le sont toutes les mentions dans les volumes des Fasti Ecclesiae Gallicanae de chanoines portant ce titre de magister sans autres précisions. L'ampleur des dépouillements rend ces données très utiles et nous devons une grande reconnaissance à John Baldwin pour avoir pris la peine de faire photocopier ses fiches et de nous les avoir transmises amicalement.

description: Deep Neural Networks (DNN) are typically tested for accuracy relying on a set of unlabelled real world data (operational dataset), from which a subset is selected, manually labelled and used as test suite. This subset is required to be small (due to manual labelling cost) yet to faithfully represent the operational context, with the resulting test suite containing roughly the same proportion of examples causing misprediction (i.e., failing test cases) as the operational dataset. However, while testing to estimate accuracy, it is desirable to also learn as much as possible from the failing tests in the operational dataset, since they inform about possible bugs of the DNN. A smart sampling strategy may allow to intentionally include in the test suite many examples causing misprediction, thus providing this way more valuable inputs for DNN improvement while preserving the ability to get trustworthy unbiased estimates. This paper presents a test selection technique (DeepEST) that actively looks for failing test cases in the operational dataset of a DNN, with the goal of assessing the DNN expected accuracy by a small and ''informative'' test suite (namely with a high number of mispredictions) for subsequent DNN improvement. Experiments with five subjects, combining four DNN models and three datasets, are described. The results show that DeepEST provides DNN accuracy estimates with precision close to (and often better than) those of existing sampling-based DNN testing techniques, while detecting from 5 to 30 times more mispredictions, with the same test suite size.

description: Rodríguez-Pose A., Psycharis Y. and Tselios V. Politics and investment: examining the territorial allocation of public investment in Greece, Regional Studies. This paper discusses how electoral politics shapes the regional allocation of public investment expenditures per capita in Greece. Using regional public investment data for ten political periods (1975–2009), combined with electoral data by constituency, a model is proposed that captures the influence of politics on the regional distribution of public investment expenditures. The results of the analysis point to a strong relationship between electoral results and regional public investment spending. Greek governing parties have tended to reward those constituencies returning them to office. Moreover, an increase in both the absolute and the relative electoral returns of the governing party in a region has traditionally been followed by greater public investment per capita in that region. Regions where the governing party (whether Liberal or Socialist) has held a monopoly of seats have been the greatest beneficiaries of this type of pork-barrel politics.
New perspectives in the duality of M-theory, heterotic strings, and F-theory

description: We discuss a new perspective on the dualities among seven-dimensional M-theory on elliptically fibered K3 surfaces, eight-dimensional (8D) heterotic strings on $T^2$, and 8D F-theory on elliptic K3 surfaces. There are several distinct small-fiber F-theory limits of a single M-theory, and we deduce that the distinct F-theory limits of an identical M-theory generally include both an F-theory limit, wherein a discrete gauge symmetry forms, and another F-theory limit, wherein a discrete gauge symmetry does not form. We also discuss constraints imposed on the degrees of discrete gauge groups and on the continuous gauge groups formed in F-theory on K3 surfaces by applying a formula that is known to hold for genus-one fibrations of K3 surfaces, and by utilizing the existence of the Jacobian fibrations.

description: Tranos E. and Mack E. A. Broadband provision and knowledge-intensive firms: a causal relationship?, Regional Studies. Despite the discussions about the importance of the digital economy, we are still far from understanding how information and communication technologies (ICTs) affect economic activity in space. Recent studies have started untangling the spatial economic impact of ICTs, highlighting the potential use of ICTs as a local development tool. This paper contributes to this domain by exploring whether broadband Internet provision can act as an attractor for knowledge-intensive business services in the United States. Using Granger causality tests, this paper addresses the simultaneity issue between broadband Internet demand and supply at the very detailed spatial level of US counties.

Gaussian Bounding Boxes and Probabilistic Intersection-over-Union for Object Detection

description: Most object detection methods use bounding boxes to encode and represent the object shape and location. In this work, we explore a fuzzy representation of object regions using Gaussian distributions, which provides an implicit binary representation as (potentially rotated) ellipses. We also present a similarity measure for the Gaussian distributions based on the Hellinger Distance, which can be viewed as a Probabilistic Intersection-over-Union (ProbIoU). Our experimental results show that the proposed Gaussian representations are closer to annotated segmentation masks in publicly available datasets, and that loss functions based on ProbIoU can be successfully used to regress the parameters of the Gaussian representation. Furthermore, we present a simple mapping scheme from traditional (or rotated) bounding boxes to Gaussian representations, allowing the proposed ProbIoU-based losses to be seamlessly integrated into any object detector.
Technological Change and Geographical Reallocation of Labour: On the Role of Leading Industries

description: Martynovich M. and Lundquist K.-J. Technological change and geographical reallocation of labour: on the role of leading industries, Regional Studies. This paper analyses inter-regional labour reallocation in Sweden over the period 1985–2008 and assesses the effects of technology-induced structural change on the ability of regions to attract and retain workers. The findings suggest that (1) the regional presence of leading industries associated with technological change has a significant effect; (2) the importance of leading industries is of dynamic character as various functional groups of leading industries play different roles at different stages of the technology-induced transformation process; and (3) while manufacturing branches act as a stabilizing factor, i.e. helping regions to retain workers, service industries drive labour reallocation in terms of attracting workers to regions.

description: Recently the leading order of the correlation energy of a Fermi gas in a coupled mean-field and semiclassical scaling regime has been derived, under the assumption of an interaction potential with a small norm and with compact support in Fourier space. We generalize this result to large interaction potentials, requiring only $|\cdot| \hat{V} \in \ell^1 (\mathbb{Z}^3)$. Our proof is based on approximate, collective bosonization in three dimensions. Significant improvements compared to recent work include stronger bounds on non-bosonizable terms and more efficient control on the bosonization of the kinetic energy.

A Deep Latent Space Model for Graph Representation Learning

description: Graph representation learning is a fundamental problem for modeling relational data and benefits a number of downstream applications. Traditional Bayesian-based graph models and recent deep learning based GNN either suffer from impracticability or lack interpretability, thus combined models for undirected graphs have been proposed to overcome the weaknesses. As a large portion of real-world graphs are directed graphs (of which undirected graphs are special cases), in this paper, we propose a Deep Latent Space Model (DLSM) for directed graphs to incorporate the traditional latent variable based generative model into deep learning frameworks. Our proposed model consists of a graph convolutional network (GCN) encoder and a stochastic decoder, which are layer-wise connected by a hierarchical variational auto-encoder architecture. By specifically modeling the degree heterogeneity using node random factors, our model possesses better interpretability in both community structure and degree heterogeneity. For fast inference, the stochastic gradient variational Bayes (SGVB) is adopted using a non-iterative recognition model, which is much more scalable than traditional MCMC-based methods. The experiments on real-world datasets show that the proposed model achieves the state-of-the-art performances on both link prediction and community detection tasks while learning interpretable node embeddings.
