description: The past twenty years have witnessed the emergence of internet conglomerates fueled by acquisitions. We build a simple model of network formation to study this. We endow firms with scarce capabilities which drive their competitiveness across markets. Firms can merge to combine their capabilities, spin-off new firms by partitioning their capabilities, or procure unassigned capabilities. We study stable industry structures in which no such deviations are profitable. We find an upper and lower bound on the size of the largest firm, and show that as markets value more of the same capabilities abrupt increases in these bounds occur.

description: In Photoacoustic imaging, Delay-and-Sum (DAS) algorithm is the most commonly used beamformer. However, it leads to a low resolution and high level of sidelobes. Delay-Multiply-and-Sum (DMAS) was introduced to provide lower sidelobes compared to DAS. In this paper, to improve the resolution and sidelobes of DMAS, a novel beamformer is introduced using Eigenspace-Based Minimum Variance (EIBMV) method combined with DMAS, namely EIBMV-DMAS. It is shown that expanding the DMAS algebra leads to several terms which can be interpreted as DAS. Using the EIBMV adaptive beamforming instead of the existing DAS (inside the DMAS algebra expansion) is proposed to improve the image quality. EIBMV-DMAS is evaluated numerically and experimentally. It is shown that EIBMV-DMAS outperforms DAS, DMAS and EIBMV in terms of resolution and sidelobes. In particular, at the depth of 11 mm of the experimental images, EIBMV-DMAS results in about 113 dB and 50 dB sidelobe reduction, compared to DMAS and EIBMV, respectively. At the depth of 7 mm, for the experimental images, the quantitative results indicate that EIBMV-DMAS leads to improvement in Signal-to-Noise Ratio (SNR) of about 75% and 34%, compared to DMAS and EIBMV, respectively.

Renormalization of the P- and T-odd nuclear potentials by the strong interaction and enhancement of P-odd effective field

description: Approximate analytical formulas for the self-consistent renormalization of P,T-odd and P-odd weak nuclear potentials by the residual nucleon-nucleon strong interaction are derived. The contact spin-flip nucleon-nucleon interaction reduces the constant of the P,T-odd potential 1.5 times for the proton and 1.8 times for the neutron. Renormalization of the P-odd potential is caused by the velocity dependent spin-flip component of the strong interaction. In the standard variant of $π+ ρ$-exchange, the conventional strength values lead to anomalous enhancement of the P-odd potential. Moreover, the $π$-meson exchange contribution seems to be large enough to generate an instability (pole) in the nuclear response to a weak potential.

description: In this paper, using a qualitative theory of dynamical systems, we study the stability of a unified dark matter-dark energy framework known as quartessence Chaplygin model (QCM) with three different equation-of-states within ultraviolet (UV) deformed Friedmann-Robertson-Walker (FRW) cosmologies without Big-Bang singularity. The UV deformation is inspired by the non-commutative (NC) Snyder spacetime approach in which by keeping the transformation groups and rotational symmetry there is a dimensionless, Planck scale characteristic parameter $μ_0$ with dual implications dependent on its sign that addresses the required invariant cutoffs for length and momentum in nature, in a separate manner. Our stability analysis is done in the $(H,ρ)$ phase space at a finite domain concerning the hyperbolic critical points. According to our analysis, due to constraints imposed on the signs of $μ_0$ from the phenomenological parameters involved in quartessence models $(Ω_m^*, c_s^2, ρ_*)$, for an expanding and accelerating late universe, all three QCMs can be stable in the vicinity of the critical points. The requirement of stability for these quartessence models in case of admission of a minimum invariant length, can yield a flat as well as non-flat expanding and accelerating universe in which Big-Bang singularity is absent. This feedback also phenomenologically credits to braneworld-like framework versus loop quantum cosmology-like one as two possible scenarios which can be NC Snyder spacetime generators (correspond to $μ_0<0$ and $μ_0>0$, respectively). As a result, our analysis show that between quartessence models with Chaplygin gas equation-of-states and accelerating FRW backgrounds occupied by a minimum invariant length, there is a possibility of viability.

A Bias-Corrected CD Test for Error Cross-Sectional Dependence in Panel Data Models with Latent Factors

description: In a recent paper Juodis and Reese (2022) (JR) show that the application of the CD test proposed by Pesaran (2004) to residuals from panels with latent factors results in over-rejection. They propose a randomized test statistic to correct for over-rejection, and add a screening component to achieve power. This paper considers the same problem but from a different perspective. It shows that the standard CD test remains valid if the latent factors are weak, and proposes a simple bias-corrected CD test, labelled CD*, which is shown to be asymptotically normal, irrespective of whether the latent factors are weak or strong. This result is shown to hold for pure latent factor models as well as for panel regressions with latent factors. The case where the errors are serially correlated is also considered. Small sample properties of the CD* test are investigated by Monte Carlo experiments and are shown to have the correct size and satisfactory power for both Gaussian and non-Gaussian errors. In contrast, it is found that JR's test tends to over-reject in the case of panels with non-Gaussian errors, and has low power against spatial network alternatives. The use of the CD* test is illustrated with two empirical applications from the literature.

description: The article investigates tasks and approaches related to the management of innovation projects, the current state of production and project management in production environment. The article gives a review of main approaches for the management of project implementation in production systems. It suggests the task of management and selection of project development paths on all the stages of project implementation. The article surveys possibilities and drawbacks of existing theories and approaches regarding planning and management tasks in project implementation. It examines general characteristics of building project management models in production-and-economic systems and their practical application. The main goal of the article is to determine gaps in the development of methods and approaches related to the management of project implementation paths as a study object based on the information about projects and their implementation environment, i.e. systems. The practical significance consists in the possibility to increase the amount of successfully implemented projects, to reduce the time period of project development stages, and to cut expenses for the implementation of project stages.
In Platforms We Trust: Misinformation on Social Networks in the Presence of Social Mistrust

description: We examine the effect of social trust on a network in which agents communicate with each other and information sources, changing their opinion with some probability. Agents whose peers are more likely to spread misinformation are consequently less trusting than agents whose neighbours are more informed, and therefore change their views with less probability. When echo chambers are strong, weakening them results in there being more interaction between high and low social trust agents, increasing the spread of misinformation. When echo chambers are weak, however, weakening them further reduces the differences in social trust, decreasing the asymmetries in communication and hence the probability agents are misinformed. As a result of the non-linear relationship between the strength of echo chambers and the spread of misinformation, optimal interventions in network structure depend on why agents form links in the first place.

With the aim of assessing the possible DNA-binding mode, the interaction of the complex 1 with calf thymus DNA (CT DNA) was investigated by UV spectroscopy, emission titration, and viscosity measurement. Also, the binding of the complex to human serum albumin (HSA) was considered by UV–Vis and fluorescence emission spectroscopy. Moreover, molecular docking was used for modeling of the binding of the complex to DNA and HSA. These experimental results were confirmed by the results of molecular docking concerning the lowest binding energy. The cytotoxicity of the heterometallic complex 1 has been evaluated against a panel of several cancer cell lines with low micromolar IC50 (72 h) values, according to its cellular uptake and also versus HEK293 nonmalignant fibroblasts. Moreover, the complex 1 showed the induction of apoptotic process. Communicated by Ramaswamy H. Sarma

We make a short recap of the Noether symmetry approach and consider the geometry for Bianchi-type I model. We obtain the exact general solutions of the theory inherently exhibited by the Noether symmetry. We also examine the cosmological implications of the model by discussing the two cases of viable scenarios. Surprisingly, we find that the predictions are nicely compatible with those of the LambdaCDM model.

description: We introduce a new class of semiparametric dynamic autoregressive models for the Amihud illiquidity measure, which captures both the long-run trend in the illiquidity series with a nonparametric component and the short-run dynamics with an autoregressive component. We develop a GMM estimator based on conditional moment restrictions and an efficient semiparametric ML estimator based on an i.i.d. assumption. We derive large sample properties for our estimators. We further develop a methodology to detect the occurrence of permanent and transitory breaks in the illiquidity process. Finally, we demonstrate the model performance and its empirical relevance on two applications. First, we study the impact of stock splits on the illiquidity dynamics of the five largest US technology company stocks. Second, we investigate how the different components of the illiquidity process obtained from our model relate to the stock market risk premium using data on the S&P 500 stock market index.

description: Modeling of planets' climate and habitability requires as fundamental input the UV emission of the hosting star. \citet{lovric2017} employed SORCE/SOLSTICE solar observations to introduce a UV color index which is a descriptor of the UV radiation that modulates the photochemistry of planets atmospheres. After correcting the SOLSTICE data for residual instrumental effects that produced asymmetric signals during different phases of the cycles analyzed, the authors found that the UV color index is linearly correlated with the Mg II index.In this paper we employ an irradiance reconstruction technique to synthetize the UV color and Mg II index with the purpose of investigating whether the correction applied by \citet{lovric2017} to SORCE/SOLSTICE data might have compensated for solar variations, and to investigate the physical mechanisms that produce such a strong correlation between the UV color index and the solar activity. Reconstructed indices reproduce very well the observations and present the same strong linear dependence. Moreover our reconstruction, which extends back to 1989, shows that the UV color - Mg II index relation can be described by the same linear relation for almost three cycles, thus ruling out an overcompensation of SORCE/SOLTICE data in the analysis of \citet{lovric2017}. We suggest that the strong correlation between the indices results from the fact that most of the Far- and Middle- UV radiation originates in the chromosphere, where atmosphere models of quiet and magnetic features present similar temperature and density gradients.

description: Subjects observe a private signal and make an initial guess; they then observe their neighbors’ guesses and update their own guess, and so forth. We study learning dynamics in three largescale networks capturing features of real-world social networks: Erdös-Rényi, Stochastic Block (reflecting network homophily) and Royal Family (that accommodates both highly connected celebrities and local interactions). We find that the Royal Family network is more likely to sustain incorrect consensus and that the Stochastic Block network is more likely to persist with diverse beliefs. These patterns are consistent with the predictions of DeGroot updating. It lends support to the notion that the use of simple heuristics in information aggregation is prevalent in large and complex networks.

description: Bitcoin, as a decentralized digital currency, has caused extensive research interest. There are many studies based on related protocols on Bitcoin, Bitcoin-based voting protocols also received attention in related literature. In this paper, we propose a Bitcoin-based decentralized privacy-preserving voting mechanism. It is assumed that there are n voters and m candidates. The candidate who obtains t ballots can get x Bitcoins from each voter, namely nx Bitcoins in total. We use a shuffling mechanism to protect voter's voting privacy, at the same time, decentralized threshold signatures were used to guarantee security and assign voting rights. The protocol can achieve correctness, decentralization and privacy-preservings. By contrast with other schemes, our protocol has a smaller number of transactions and can achieve a more functional voting method.

description: This paper provides the first proof of concept that naturally occurring transaction data, arising from the decentralized activity of millions of economic agents, can be harnessed to produce national accounts-like objects. We deploy comprehensive transaction-level data and its associated metadata arising from the universe of Spanish retail accounts of Banco Bilbao Vizcaya Argentaria (BBVA). We organize the resulting 3 billion individual transactions by 1.8 million bank customers in a large and highly detailed representative consumption panel to show (i) that the aggregation of such data, once organized according to national accounting principles, can reproduce current official statistics on aggregate consumption in the national accounts with a high degree of precision and, as a result of the richness of transaction data, (ii) produce novel, highly detailed distributional accounts for consumption. Finally, exploiting the panel nature of our data, we (iii) offer a non-parametric analysis of individual consumption dynamics across the consumption distribution.

description: A survey was conducted among residents of Singapore to assess their knowledge, attitude and practices towards plastic reduction efforts of the government.There are numerous programs and policies being implemented to address the issue on plastic waste, even more on general waste in Singapore but significant membersof the public seem to lack awareness on everything that’s being implemented and not, how are these programs and policies being implemented and what should be done to comply and engage with them, though their willingness to take part in all these are unquestionable based on a previous study. Some of the government’s efforts arepalpable in the community such as the Mandatory Packaging Reporting (MPR) agreement with the packaged products producers which is the key for the implementation of Extended Producer Responsibility (EPR) framework for managing end-of-life packaging by the packaging products producers themselves, and reducing the use of disposable carrier bags from all major supermarkets island wide wherein disposable carrier bags are chargeable to consumers, while other programs are not widely known, but whether the effects of all these efforts are significant remain uncertain.

description: The “tragedy of the commons” describes a variety of social dilemmas where total economic sur- plus is produced jointly from collective behavior and where individuals can strategically manipu- late their share of the surplus. Recent research has shown that it is possible to test nonparametri- cally whether observed behavioral data are consistent with the canonical average return game, in which players share joint output in proportion to their inputs. We show that these tests extend to a much broader range of games, including equal-sharing of joint output, weighted averages of equal-sharing and proportionate sharing, and the average cost game, in which players share joint costs in proportion to the service provided them.

description: Air pollution is becoming a global environmental problem, in both developed and developing countries. It has greatly impacted the health and lives of millions of people, thus increasing mortality rates and pollution induced diseases reports. This paper proposes machine learning methods for predicting the rates of possibly increased air pollution in several areas, by processing the gathered data from multiple weather and air quality meter stations. The data has been gathered over a period of several years including air quality and pollution data and weather data including temperature, humidity and wind characteristics. The development process included feature extraction, feature selection for removing redundancy, and finally training multiple regression models and hyperparameter optimization. Pollutants and air quality index (AQI) were used as target variables, and appropriate regression models were trained. The performed experiments show that XGBoost is the most accurate, achieving MAE of 8.9 for Center, 8.9 for Karpos and 7.3 for Kumanovo municipality for the PM10 pollutant. The improvements over the baseline, Dummy regressor are significant, reducing the MAE for 12 on average.

description: Majorana masses of the neutrino implies lepton number violation and is intimately related to the lepton asymmetry of the universe, which gets related to the baryon asymmetry of the universe in the presence of the sphalerons during the electroweak phase transition. Assuming that the baryon asymmetry of the universe is generated before the electroweak phase transition, it is possible to dicriminate different classes of models of neutrino masses. While see-saw mechanism and the triplet higgs mechanism are preferred, the Zee-type radiative models and the R-parity breaking models requires additional inputs to generate baryon asymmetry of the universe during the electroweak phase transition.

description: Spin-polarization response functions are examined for high-energy $(\vec{e},e'\vec{p})$ reaction by computing the full 18 response functions for the proton kinetic energy $T_{p'}=$ 0.515 GeV and 3.179 GeV with an 16O target. The Dirac eikonal formalism is applied to account for the final-state interactions. The formalism is found to yield the response functions in good agreement with those calculated by the partial-wave expansion method at 0.515 GeV. We identify the response functions that depend on the spin-orbital potential in the final-state interactions, but not on the central potential. Dependence on the Dirac- or Pauli-type current of the nucleon is investigated in the helicity-dependent response functions, and the normal-component polarization of the knocked-out proton, $P_n$, is computed.

Type IV singular bouncing cosmology from $f(T)$ Gravity

description: We investigate bouncing scenario in the modified $f(T)$ gravity, $T$ being the torsion scalar. Attention is attached to the reconstruction of $f(T)$ able to describe type IV singular bouncing evolution, where we adopt as assumption that the bouncing and type IV singularity points coincide. In the context of the reconstructed $f(T)$ model we calculate the Hubble slow-roll parameters in order to determine the dynamical evolution of the cosmological system under study. The results show that the Hubble slow-roll parameters become singular at the type IV singularity indicating a dynamical instability. Moreover we perform the stability analysis of the $f(T)$ gravity solution where, according to the obtained result, the type IV singularity point is a saddle point in agreement with the bounce scenario.

Sieve method

description: In this paper, we study a class of high dimensional moment restriction panel data models with interactive effects, where factors are unobserved and factor loadings are nonparametrically unknown smooth functions of individual characteristics variables. We allow the dimension of the parameter vector and the number of moment conditions to diverge with sample size. This is a very general framework and includes many existing linear and nonlinear panel data models as special cases. In order to estimate the unknown parameters, factors and factor loadings, we propose a sieve-based generalized method of moments estimation method and we show that under a set of simple identification conditions, all those unknown quantities can be consistently estimated. Further we establish asymptotic distributions of the proposed estimators. In addition, we propose tests for over-identification, specification of factor loading functions, and establish their large sample properties. Moreover, a number of simulation studies are conducted to examine the performance of the proposed estimators and test statistics in finite samples. An empirical example on stock return prediction is studied to demonstrate the usefulness of the proposed framework and corresponding estimation methods and testing procedures.
Economic Theory and Policy Today: Lessons from Barbara Wootton and the Creation of the British Welfare State

description: This article investigates Barbara Wootton’s contribution to the creation of the welfare state in Britain through her interpretation and adaptation of economic theory to support social policy. It revisits Wootton’s Lament for Economics (1938) and explores unpublished archives showing her considerable engagement in public discussions on government spending, employment, poverty alleviation and her interaction with William Beveridge’s epoch defining welfare plan for Britain. We claim that her critique of economic theory for being an abstract science confined to equilibrium states, combined with her acute observation of social reality, allowed Wootton to cut free from established modes of economic thought. This laid the foundation for pioneering insights justifying an interventionist welfare state based on real-world issues and concepts of social justice, rather than self-interest and market failure principles.

description: Latest developments in crowd-sourcing and inter-user information sharing has led to the idea of sharing crucial information about a near disaster. Having this information can decrease the number of casualties. If people are aware of a near disaster, they can more easily avoid it, which in term, can minimize the damage it makes. The fastest way to get informed, in these situations, is by having peer information and on-time alert. Users of the social networks, have shown, over the years, that they can share information fast in time of a crisis. This type of information sharing is commonly known as crowd-sourcing. In this paper, we propose an android awareness platform called Bewared, which, in term, allows users of the social networks to collaborate, share information and pinpoint a natural disaster with its location. The types of natural disasters, used in this research, are: earthquakes, fires, floods, fire and their level of validity. The application uses some of the existing platforms and social media networks. In our case, Bewared is supported by Facebook due to its option (application interface) to geographically locate each user of the network, by using their mobile device its real time interaction possibilities.

description: We determine the scalar field evolution of a braneworld localized black hole with both dark matter and dark energy components, obtained within a dynamical and continuous embedding formalism by use of Nash's theorem. We further extract the associated quasinormal modes for both de Sitter-Schwarzschild-Dark matter and anti-de Sitter-Schwarzschild-Dark matter solutions, for the different causal structures (one, two or three horizon spacetimes) given by the space of parameters. By comparison with standard General Relativity solutions, we infer possible observable astrophysical differences, and remark on modifications to previous AdS/CFT correspondence scenarios.

description: The paper uses a social cost benefit analysis (SCBA) approach to measure the effects of the power system reform starting from 2015 in Jiangsu province, China. We review the background of Jiangsu power system and summarize the implemented policies since the publication of “Document #9”. Then we pick the average industrial and commercial retail price and analyse the sources of price reductions. We show that the nominal industrial and commercial price fell by 21.3% between January 2012 and May 2021. We then analyse the likely overall welfare change facing industrial and commercial customers using SCBA and conclude that there is a permanent gain equivalent to 9.1% lower prices per year mainly because of the reform. This figure is a significantly more positive consumer gain than that calculated in previous SCBAs of electricity reform in other countries.

description: The frequency-domain Kalman filter (FKF) has been utilized in many audio signal processing applications due to its fast convergence speed and robustness. However, the performance of the FKF in under-modeling situations has not been investigated. This paper presents an analysis of the steady-state behavior of the commonly used diagonalized FKF and reveals that it suffers from a biased solution in under-modeling scenarios. Two efficient improvements of the FKF are proposed, both having the benefits of the guaranteed optimal steady-state behavior at the cost of a very limited increase of the computational burden. The convergence behavior of the proposed algorithms is also compared analytically. Computer simulations are conducted to validate the improved performance of the proposed methods.

description: With the rapid growth of the Internet community, some of the simple and familiar tasks related to the field of data transfer are becoming increasingly complex. A modern worldwide network can offer high-speed channels and many opportunities for IT companies that provide high load through the Internet. This creates a bunch of new problems for software solutions and algorithms in the field of high-speed digital c ommunications. This article observes one of these problems: the mutual influence between two mutually opposite single-threaded TCP flows with the various congestion control algorithms. In this paper, some of the most efficient congestion control algorithms were tested on a real network using channel emulation equipment. The test results presented in the article show that two-way TCP data transfer with modern congestion control algorithms can lead to a significant performance drop.
