description: Comparative methods involving DNA-DNA hybridization are thought to be reliable in terms of phylogeny reconstruction, but also weigh heavy on computational resources. Processing large-scale genomic datasets can have potentially unfavorable drawbacks in computing, which can result in poor analysis leading to erroneous conclusions. Slim genomic datasets, such as those found in entire sets of complete mitochondrial DNA (mtDNA), are lucrative options for researchers seeking complete genomic datasets that fit the criteria of a computationally light model. Yet, a handful of incorrect conclusions in molecular phylogenetics have also raised questions about its reliability. This article seeks to emphasize a simplified approach to phylogeny research using complete mitochondrial genomes alone, while touching upon a number of technological perspectives, such as algorithmic selection, which can help improve accuracy and performance in comparative analysis. Moreover, my results will show that reliable estimations can be obtained by using mitochondrial markers, even among time-extended taxonomical rankings; although, admittedly, precise taxonomical boundaries for accurate resolution using complete sequences of mtDNA remain unclear, and it should be explored further. Six distinct mammalian groups of taxa were selected for comparison. In all cases, mtDNA models generated reliable phylogeny approximations when compared against other independent data, while rendering exceptional computational performance.
Mapping Religion, Space, and Economic Outcomes in Indian Cities

description: 



We deploy a socio-spatial approach and use a spatially representative survey that we conducted in Hyderabad and Mumbai to analyze the relation between city space and religion. After documenting the relative status of religious groups in urban India and different types of cities using secondary databases, we identify poor-ghettos and elite-enclaves in Hyderabad and Mumbai. In both cities, ghettos have a high proportion of Muslims, while enclaves are dominated by non-Muslim inhabitants. Ghettoization of Muslims is far more pronounced in Hyderabad than in Mumbai. A key finding on the relation between city space and religion is that compared to segregated neighborhoods, mixed (“grayer”) neighborhoods produce better economic outcomes like lower poverty. We argue that while Indian cities are becoming less integrated along religious lines over the last 3-4 decades, this process is far from complete, and needs to be reversed.
Path Dependence and Stagnation in a Classical Growth Model

Publisher: name: University of Massachusetts Amherst

description: 



This paper embeds a technical progress function in a classical growth model and studies the effects of permanent changes in parameters and temporary shocks such as pandemics. Technical change is driven by dynamic economies of scale and responds to distributional forces: the wage share regulates labor-saving technical change and employment regulates its capital- using bias. The model features path dependence in the employment-population rate and the output-capital ratio. Population growth and distribution can respond to the employment rate. Interpreted through the model, secular stagnation under neoliberal capitalism has been driven by a combination of diminished investment and reduced worker bargaining power more than by slower technical change and population growth. A temporary unfavorable shock to the output- capital ratio will permanently reduce the employment rate. In the fully endogenous model, this will increase the profit share and reduce the rates of technical change, capital accumulation, and population growth.
Embeddings of 3-manifolds in S^4 from the point of view of the 11-tetrahedron census

description: This is a collection of notes on embedding problems for 3-manifolds. The main question explored is `which 3-manifolds embed smoothly in the 4-sphere?' The terrain of exploration is the Burton/Martelli/Matveev/Petronio census of triangulated prime closed 3-manifolds built from 11 or less tetrahedra. There are 13766 manifolds in the census, of which 13400 are orientable. Of the 13400 orientable manifolds, only 149 of them have hyperbolic torsion linking forms and are thus candidates for embedability in the 4-sphere. The majority of this paper is devoted to the embedding problem for these 149 manifolds. At present 41 are known to embed. Among the remaining manifolds, embeddings into homotopy 4-spheres are constructed for 4. 67 manifolds are known to not embed in the 4-sphere. This leaves 37 unresolved cases, of which only 3 are geometric manifolds i.e. having a trivial JSJ-decomposition.

description: Under certain topological assumptions, we show that two monotone Lagrangian submanifolds embedded in the standard symplectic vector space with the same monotonicity constant cannot link one another and that, individually, their smooth knot type is determined entirely by the homotopy theoretic data which classifies the underlying Lagrangian immersion. The topological assumptions are satisfied by a large class of manifolds which are realised as monotone Lagrangians, including tori. After some additional homotopy theoretic calculations, we deduce that all monotone Lagrangian tori in the symplectic vector space of odd complex dimension at least five are smoothly isotopic.

The Nature of Money and the Theory of International Trade: Thornton and Ricardo

description:
A rich recent literature reinvestigates the nature of money, but little attention has been paid to the ramifications of the ways in which we theorize money for the theory of international trade.This paper examines the logical relationship between the neutrality of money and selfbalancing trade based on Henry Thornton and David Ricardo as two foundational contributions to credit and commodity money theories respectively. I show that both authors theorize trade as self-balancing whenever money is conceptualized as neutral. I distinguish two notions of the neutrality of money: ex ante and ex post neutrality. In Thornton’s Paper Credit money is not neutral ex ante: there can be temporary trade imbalances. But in the long-run money is neutral ex post and international trade boils down to self-balancing barter. In Ricardo money is neutral both ex ante and ex post and international trade is always balanced unless central bank policy undermines monetary neutrality.

description: Selective optical excitation of a substrate lattice can drive phase changes across hetero-interfaces. This phenomenon is a non-equilibrium analogue of static strain control in heterostructures and may lead to new applications in optically controlled phase change devices. Here, we make use of time-resolved non-resonant and resonant x-ray diffraction to clarify the underlying physics, and to separate different microscopic degrees of freedom in space and time. We measure the dynamics of the lattice and that of the charge disproportionation in NdNiO3, when an insulator-metal transition is driven by coherent lattice distortions in the LaAlO3 substrate. We find that charge redistribution propagates at supersonic speeds from the interface into the NdNiO3 film, followed by a sonic lattice wave. When combined with measurements of magnetic disordering and of the metal-insulator transition, these results establish a hierarchy of events for ultrafast control at complex oxide hetero-interfaces.

The (Im-)Possibility of Rational Socialism: Mises in China’s Market Reform Debate
Creators: name: Weber, Isabella
Publisher: name: University of Massachusetts Amherst
Year: 2021

description: 



Investigate the long first decade of reform in China (1978-1992) to show that Mises, in particular his initiating contribution to the Socialist Calculation Debate, became relevant to the reconfiguration of China’s political economy when the reformers gave up on the late Maoist primacy of continuous revolution and adhered instead to an imperative of development and catching up. During the Cultural Revolution, Mao had rejected the notions of efficiency and rational economic management. In the late 1970s, the reformers under Deng Xiaoping’s leadership elevated these notions to highest principle. As a result, Mises’ critique that socialism could not achieve a rational economic order came to be debated throughout the 1980s and Chinese economists developed their own reading of Mises and the Socialist Calculation Debate. When Deng Xiaoping reinstated market reforms in the early 1990s after the Tiananmen crackdown, a history of thought review of the possibility of rational socialism and socialist markets helped to justify the Socialist Market Economy with Chinese Characteristics the official designation of China’s economic system to this day.
A general mathematical framework for understanding the behavior of heterogeneous stem cell regeneration

description: Stem cell heterogeneity is essential for the homeostasis in tissue development. This paper established a general formulation for understanding the dynamics of stem cell regeneration with cell heterogeneity and random transitions of epigenetic states. The model generalizes the classical G0 cell cycle model, and incorporates the epigenetic states of stem cells that are represented by a continuous multidimensional variable and the kinetic rates of cell behaviors, including proliferation, differentiation, and apoptosis, that are dependent on their epigenetic states. Moreover, the random transition of epigenetic states is represented by an inheritance probability that can be described as a conditional beta distribution. This model can be extended to investigate gene mutation-induced tumor development. The proposed formula is a generalized formula that helps us to understand various dynamic processes of stem cell regeneration, including tissue development, degeneration, and abnormal growth.

Stranded Fossil-Fuel Assets Translate into Major Losses for Investors in Advanced Economies
Creators: name: Semieniuk, Gregor
Publisher: name: University of Massachusetts Amherst
Year: 2021

description: 



The distribution of ownership of transition risk associated with stranded fossil-fuel assets remains poorly understood. We compute global stranded assets of US$1.4 trillion in the upstream oil and gas sector as expectations change to be consistent with stated climate policies. We trace the equity risk ownership from these 43,439 assets through a global equity network of 1.8 million companies to their ultimate owners. Most of the market risk falls on private investors, overwhelmingly in OECD countries, including substantial exposure through pension funds. Financial markets are exposed to a US$690 billion correction, comparable to the mispricing that triggered the 2007-08 crisis. The ownership distribution also shows the large stake OECD investors have in the continued operation of fossil-fuel facilities incompatible with climate change mitigation goals.

description: We obtain the perturbative expansion of the free energy on $S^4$ for four dimensional Lagrangian ${\cal N}=2$ superconformal field theories, to all orders in the 't Hooft coupling, in the planar limit. We do so by using supersymmetric localization, after rewriting the 1-loop factor as an effective action involving an infinite number of single and double trace terms. The answer we obtain is purely combinatorial, and involves a sum over tree graphs. We also apply these methods to the perturbative expansion of the free energy at finite $N$, and to the computation of the vacuum expectation value of the 1/2 BPS circular Wilson loop, which in the planar limit involves a sum over rooted tree graphs.

Does Project-Level Foreign Aid Increase Access to Improved Water Sources? Evidence from Household Panel Data in Uganda
Creators: name: Pickbourn, Lynda Joyce
Publisher: name: University of Massachusetts Amherst
Year: 2021

description: 



This paper combines geocoded subnational data on the location of water, sanitation and hygiene (WASH) aid projects in Uganda with nationally representative household-level panel survey data to evaluate the impact of WASH aid on access to water and on the burden of water collection. Specifically, it examines whether proximity to aid-funded WASH projects improves household access to improved water sources and reduces the time burden of water collection. Our results suggest that while aid-funded WASH projects increase household access to improved sources of water, households may also see the time burden of water collection increase, as they may need to travel longer distances and also experience longer wait times due to congestion at water service points. This is an indication that the supply of improved water sources is still insufficient relative to demand as measured by the population density.

description: The development of a satisfying and rigorous mathematical understanding of the performance of neural networks is a major challenge in artificial intelligence. Against this background, we study the expressive power of neural networks through the example of the classical NP-hard Knapsack Problem. Our main contribution is a class of recurrent neural networks (RNNs) with rectified linear units that are iteratively applied to each item of a Knapsack instance and thereby compute optimal or provably good solution values. We show that an RNN of depth four and width depending quadratically on the profit of an optimum Knapsack solution is sufficient to find optimum Knapsack solutions. We also prove the following tradeoff between the size of an RNN and the quality of the computed Knapsack solution: for Knapsack instances consisting of $n$ items, an RNN of depth five and width $w$ computes a solution of value at least $1-\mathcal{O}(n^2/\sqrt{w})$ times the optimum solution value. Our results build upon a classical dynamic programming formulation of the Knapsack Problem as well as a careful rounding of profit values that are also at the core of the well-known fully polynomial-time approximation scheme for the Knapsack Problem. A carefully conducted computational study qualitatively supports our theoretical size bounds. Finally, we point out that our results can be generalized to many other combinatorial optimization problems that admit dynamic programming solution methods, such as various Shortest Path Problems, the Longest Common Subsequence Problem, and the Traveling Salesperson Problem.

Regulated Market, Trapped Workers: The Impacts of the "Tolerant and Prudent" Policy on Labour Precarity in China’s Online Ridehailing Sector
Creators: name: Zhang, Wei
Publisher: name: University of Massachusetts Amherst
Year: 2021

description: 

Since 2017, China has adopted the "tolerant and prudent" policy in regulating emerging digital platform industries. The impacts of this policy on labour precarity have been rarely studied. Drawing on an original survey of over 600 ride-hailing drivers in two Chinese cities, Nanjing and Beijing, we conduct a political economy analysis for a three-party framework involving the municipal government, capital, and labour. We find that, in accordance with the "tolerant and prudent" principle, municipal governments stipulated regulations regarding the qualifications of ride-hailing vehicles and drivers. These regulations, although they can help reduce labour precarity in the marketplace for licensed drivers, have exacerbated precarity in the workplace. Specifically, in response to the regulations, the ride-hailing platforms aligned with third- party rental companies that provided licensed vehicles. This arrangement has effectively trapped many ride- hailing drivers in the industry: our quantitative analysis shows that drivers bounded by a rental or rent-to- own agreement worked significantly longer hours than counterparts who steered their own vehicles.

The Impact of Environmental Regulations on Manufacturing Outsourcing: Re-examining the Pollution Haven Effect in Global Value Chains
Creators: name: Li, An
Publisher: name: University of Massachusetts Amherst
Year: 2021

description: 



As countries worldwide attempt to address a series of global and domestic environmental challenges, the pollution haven effect remains an ongoing concern among trade and environment researchers and policymakers. This paper examines the pollution haven effect in the context of global value chains using inter-country input-output data at the manufacturing industry level from 1995-2009. This paper pays special attention to the issue of “double- counting” caused by intermediate trade. The analysis utilizes two outsourcing measures and two revealed comparative advantage measures appropriate for analyzing global value chains. I propose women’s political power as a novel instrumental variable to address the endogeneity of environmental regulation. Regression results show that more stringent environmental policies are not a significant determinant of manufacturing outsourcing and competitiveness in global value chains. At the same time, women’s political power is associated with more stringent environmental policies.

description: Next generation cosmic microwave background spectral distortion and pulsar timing array experiments have the potential to probe primordial fluctuations at small scales with remarkable sensitivity. We demonstrate the potential of these probes to either detect signatures of primordial black holes (PBHs) sourced from primordial overdensities within the standard thermal history of the universe over a 13-decade mass range ${\cal O}(0.1-10^{12})M_\odot$, or constrain their existence to a negligible abundance. Our conclusions are based only on global cosmological signals, and are robust under changes in i) the statistical properties of the primordial density fluctuations (whether Gaussian or non-Gaussian), ii) the merger and accretion history of the PBHs and assumptions about associated astrophysical processes, and iii) clustering statistics. Any positive detection of enhanced primordial fluctuations at small scales would have far-reaching implications from the content of dark matter to origin of BHs in the centers of galaxies, and to the field content of the inflation. On the other hand, their non-detection would also have important corollaries. For example, non-detection up to forecast sensitivities would tell us that PBHs larger than a fraction of a solar mass can constitute no more than a negligible fraction of dark matter. Moreover, non-detection will also rule out the scenario that PBHs generated by primordial overdensities could be the progenitors of super-massive black holes (SMBHs), of topical interest as there are only a few widely accepted proposals for the formation of SMBHs, an even more pressing question after the detection of active galactic nuclei over a billion solar masses at redshifts $z \geq 7$. Finally, non-detection sets the strongest bounds on the amplitude of small scale inflationary fluctuations for over 6 decades.

The State-Constituted Market Economy: A Conceptual Framework for China’s State–Market Relations

description: 



China has created a distinct economic system. Yet despite a growing literature with valuable contributions on the institutional arrangements under ‘capitalism with Chinese characteristics’, the precise economic mechanisms underpinning China’s state–market relations remain undertheorised. In this paper we develop a conceptual framework of what we call China’s state-constituted market economy. We define essential as ‘systemically significant from the perspective of the state’. We argue that the Chinese state ‘constitutes’ the market economy by creating, participating and steering markets for essentials in order to stabilise and guide the economy as a whole. We draw on China’s statecraft tradition as well as on proposals for financial policy reform in the US to conceptualise the state market- constitution in China.

U.S. Monetary Policy and the Decline in the Interest Rates (1990-2007)
Creators: name: Capraro, Santiago
Publisher: name: University of Massachusetts Amherst
Year: 2021

description: 



Interest rates in the US and in other countries have experienced persistent and generalised declines since the 1980s. The main interpretations of this phenomenon ignore the role of monetary factors, such as financial and monetary policy. The essay proposes an alternative interpretation based on the choice of the Federal Reserve (FED) to conduct monetary policy by attributing high priority to financial stability. The interaction between changes in financial regulation, the transformation of "specialized" into "universal” banking, and the concern with financial instability have led the central bank to add to the role of "lender of last resort" that of "lender of first resort", which systematically provides liquidity at a low cost to financial firms. This new conduct of monetary policy has produced the downward trend in interest rates.

This result generalizes to a knot in an integer homology 3-sphere and surfaces in certain simply connected signature zero 4-manifolds cobounding this homology sphere. Using the Blanchfield characterization, we obtain effective lower bounds for the Z-slice genus from the linking pairing of the double branched covering of the knot. In contrast, we show that for odd primes p, the linking pairing on the first homology of the p-fold branched covering is determined up to isometry by the action of the deck transformation group on said first homology. As an application of the new upper and lower bounds, we complete the calculation of the Z-slice genus for all prime knots with crossing number up to 12.

Predicting Chinese Banking Policy Incidence

Publisher: name: University of Massachusetts Amherst
Year: 2021

description:
In this exploratory research, we examine the effect of economic and noneconomic indicators on the creation of Chinese Banking and Insurance Regulatory Commission policies using a VAR model. We find that CBIRC policies are predicted by State Council construction policies and policies set by the State Administration of Foreign Exchange. This indicates that the CBIRC is inward-looking, observing what other regulators are doing rather than responding to changes in the real and financial economy. This may be a product of market distortions due to China’s unique blend of state-oriented and market-based institutions.

description: We study ancestral structures for the two-type Moran model with mutation and frequency-dependent selection under the nonlinear dominance or fittest-type-wins scheme. Under appropriate conditions, both lead, in distribution, to the same type-frequency process. Reasoning through the mutations on the ancestral selection graph (ASG), we develop the corresponding killed and pruned lookdown ASG and use them to determine the present and ancestral type distributions. To this end, we establish factorial moment dualities to the Moran model and a relative. We extend the results to the diffusion limit and present applications for finite population size as well as moderate and weak selection.

description: We consider $3d$ $\mathcal{N}\!=\!2$ gauge theories with fundamental matter plus a single field in a rank-$2$ representation. Using iteratively a process of "deconfinement" of the rank-$2$ field, we produce a sequence of Seiberg-dual quiver theories. We detail this process in two examples with zero superpotential: $Usp(2N)$ gauge theory with an antisymmetric field and $U(N)$ gauge theory with an adjoint field. The fully deconfined dual quiver has $N$ nodes, and can be interpreted as an Aharony dual of theories with rank-$2$ matter. All chiral ring generators of the original theory are mapped into gauge singlet fields of the fully deconfined quiver dual.

description: An articulated body is defined as a finite number of rigid bodies connected by a set of arbitrary constraints that limit the relative motion between pairs of bodies. Such a general definition encompasses a wide variety of situations in the microscopic world, from bacteria to synthetic micro-swimmers, but it is also encountered when discretizing inextensible bodies, such as filaments or membranes. Simulating suspensions of such articulated bodies requires to solve the hydrodynamic interactions between large collections of objects of arbitrary shape while satisfying the multiple constraints that connect them. Two main challenges arise in this task: limiting the cost of the hydrodynamic solves, and enforcing the constraints within machine precision at each time-step. To address these challenges we propose a formalism that combines the body mobility problem in Stokes flow with a velocity formulation of the constraints, resulting in a mixed mobility-resistance problem. While resistance problems are known to scale poorly with the particle number, our preconditioned iterative solver is not sensitive to the system size. Constraint violations, e.g. due to discrete time-integration errors, are prevented by correcting the particles' positions and orientations at the end of each time-step. Our correction procedure, based on a nonlinear minimisation algorithm, is negligible in terms of computational cost and preserves the accuracy of the time-integration scheme. We showcase the robustness and scalability of our method by exploring the locomotion modes of a model microswimmer inspired by the diatom colony Bacillaria Paxillifer, and by simulating large suspensions of bacteria interacting near a no-slip boundary. Finally, we provide a Python implementation of our framework in a collaborative publicly available code.

description: We propose new confining dualities in $3d$ $\mathcal{N}\!=\!2$ gauge theories with orthogonal gauge groups, with and without monopole superpotentials. Deriving some of those dualities requires a sequence of gauging and Higgsing for a $\mathbb{Z}_2$ symmetry. This prevents the gauge theory from developing a smooth quantum moduli space and affects the global structure of the gauge group, muting it from $SO$ to $O_+$ . The confining dualities provide tools to deconfine fields transforming in the symmetric rank-$2$ representation of classical gauge groups. As an application, we propose and derive S-confining dualities for $SO(N)$ $(Sp(N))$ gauge theories with an adjoint and $1$ $(2)$ fundamentals, respectively. From these S-confining dualities, we readily obtain various duality appetizers and the $3d$ mirror of $A_{2N}$ Argyres-Douglas theories.

description: Novel fermions with relativistic linear dispersion can emerge as low-energy excitations in topological semimetal materials. Here, we show that the orbital moment contribution in the circular photomagnetic effect for these topological semimetals exhibit an unconventional $ω^{-1}$ frequency scaling, leading to significantly enhanced response in the low frequency window, which can be orders of magnitude larger than previous observations on conventional materials. Furthermore, the response tensor is directly connected to the Chern numbers of the emergent fermions, manifesting their topological character. Our work reveals a new signature of topological semimetals and suggests them as promising platforms for optoelectronics and spintronics applications.

description: As quantum devices become more complex and the requirements on these devices become more demanding, it is crucial to be able to verify the performance of such devices in a scalable and reliable fashion. A cornerstone task in this challenge is quantifying how close an experimentally prepared quantum state is to the desired one. Here we present a method to construct an estimator for the quantum state fidelity that is compatible with any measurement protocol. Our method provides a confidence interval on this estimator that is guaranteed to be nearly minimax optimal for the specified measurement protocol. For a well-chosen measurement scheme, our method is competitive in the number of measurement outcomes required for estimation. We demonstrate our method using simulations and experimental data from a trapped-ion quantum computer and compare the results to state-of-the-art techniques. Our method can be easily extended to estimate the expectation value of any observable, such as entanglement witnesses.

Late-Time Anisotropy Sourced by a 2-Form Field Non-Minimally Coupled to Cold Dark Matter

description: This paper investigates the cosmological dynamics arising from the interaction between a 2-form field and cold dark matter within a Bianchi I background. Employing a dynamical system analysis, we identify two attractors yielding to exponential expansion of the Universe, i.e., de-Sitter solutions. Notably, these solutions exhibit a pivotal distinction: one is indistinguishable from the cosmological constant scenario, while the other corresponds to an \emph{anisotropic de-Sitter} expansion sourced by the 2-form field. To validate the asymptotic behavior of our model, we conduct a numerical exploration of its expansion history. Our analysis reveals that the coupling between the dark sectors amplifies the shear during the matter-dominated epoch, offering a potential avenue to address certain observational discrepancies related to the structure formation process. Then, we constrain the parameter space of the model using recent observational datasets. Remarkably, we find that the current shear is precisely constrained to be approximately $Σ_0 \approx - 10^{-4}$. We also discuss some key differences in the expansionary dynamics sourced by the 2-form field compared to a 1-form field, i.e., a vector field, offering insights into their respective impacts on the support they provide to late-time anisotropy.

description: The main goal of this note is to provide a First-Order Logic with Betweenness (FOLB) axiomatization of the main classes of graphs occurring in Metric Graph Theory, in analogy to Tarski's axiomatization of Euclidean geometry. We provide such an axiomatization for weakly modular graphs and their principal subclasses (median and modular graphs, bridged graphs, Helly graphs, dual polar graphs, etc), basis graphs of matroids and even $Δ$-matroids, partial cubes and their subclasses (ample partial cubes, tope graphs of oriented matroids and complexes of oriented matroids, bipartite Pasch and Peano graphs, cellular and hypercellular partial cubes, almost-median graphs, netlike partial cubes), and Gromov hyperbolic graphs. On the other hand, we show that some classes of graphs (including chordal, planar, Eulerian, and dismantlable graphs), closely related with Metric Graph Theory, but defined in a combinatorial or topological way, do not allow such an axiomatization.
