Unveiling Latent Structure of Venture Capital Syndication Networks

Venture capital (VC) is a form of private equity financing provided by VC institutions to startups with high growth potential due to innovative technology or novel business models but also high risks. To against uncertainties and benefit from mutual complementarity and sharing resources and information, making joint-investments with other VC institutions on the same startup are pervasive, which forms an ever-growing complex syndication network. Attaining objective classifications of VC institutions and revealing the latent structure of joint-investment behaviors between them can deepen our understanding of the VC industry and boost the healthy development of the market and economy. In this work, we devise an iterative Loubar method based on the Lorenz curve to make objective classification of VC institutions automatically, which does not require setting arbitrary thresholds and the number of categories. We further reveal distinct investment behaviors across categories, where the top-ranked group enters more industries and investment stages with a better performance. Through network embedding of joint investment relations, we unveil the existence of possible territories of top-ranked VC institutions, and the hidden structure of relations between VC institutions.

A general hypothesis of forest invasions by woody plants based on whole‐plant carbon economics

Abstract Although closed‐canopy forests are characterized by low‐light availability and slow population dynamics, many are under threat from non‐native, invasive woody species that combine high colonization ability and fast growth potential with high low‐light survival. This ‘superinvader’ phenotype contravenes expected trade‐offs predicted by successional niche theory, posing a challenge to both invasion and forest succession theory. We propose a parsimonious conceptual model based on the whole‐plant light compensation point (WPLCP) that, across a variety of plant strategies and growth forms, can explain greater competitive abilities of forest invaders in the context of both high‐light growth rate and shade tolerance. The model requires only that non‐native species experience relatively fewer carbon costs than native species, enabling resource‐acquisitive species to establish in low‐light conditions. We review evidence for lower carbon costs in invasive species resulting from (1) enemy release, (2) recent environmental changes that favour less stress‐tolerant phenotypes and (3) phylogenetically constrained native floras. We also discuss implications of invader shade tolerance in the context of other life‐history strategies that, combined with canopy disturbances, facilitate their rapid numerical dominance. Synthesis. An invasion framework driven by carbon dynamics suggests renewed focus on whole‐plant carbon costs, including below‐ground respiration and tissue turnover, which are rarely measured in functional studies of forest invaders.

A comparative study of mouse bone marrow mesenchymal stem cells isolated using three easy-to-perform approaches.

Mouse bone marrow mesenchymal stem cells (mBM-MSCs) are important for preclinical tissue regeneration and repair studies. In the present study, we isolated mBM-MSCs using three easy-to-perform methods (whole bone marrow-adherent culture, density-gradient centrifugation, and bone digestion), and then compared the morphology, proliferation, differentiation, and paracrine factor profiles of the isolated mBM-MSCs. Of these three isolation methods, the bone digestion method resulted in the highest quantity of mBM-MSCs with high growth potential and moderate differentiation. Conversely, the mBM-MSCs isolated through the whole bone marrow-adherent method exhibited the lowest potency for proliferation and differentiation. The differentially expressed factors between mBM-MSCs were primarily those involved in immune responses. The highly expressed secreted factors included cytokines/members of the chemokine family, growth factors, and protein binding/proteinase activity. These findings provide a fundamental reference for development of MSC isolation methods.

Projection of passenger cars’ air pollutants and greenhouse gas emissions and fuel consumption in Tehran under alternative policy scenarios

Passenger cars (PCs) are a major contributor to urban air pollution, greenhouse gas emissions, and energy security challenges in megacities in developing countries because of their high growth potential. Since the PC fleet changes through time, the projection of air pollutant emissions from PCs is essential for effective emission reduction policymaking. However, the extensive amount of data and proper models are required for this purpose that are not available in many developing countries. Hence, this study develops multiple econometric and emission models and integrate them into a framework to simulate the future stock and activity of PCs and projects PCs’ air pollutants and CO2 emissions and fuel consumption in the megacity of Tehran by 2035. Various data treatments and estimations are used in response to poor transport-related data availability at the city-level. Eight alternative scenarios are considered to assess the effectiveness of different fuel consumption and emission reduction policies. Projections show that the PC stock will grow 70% by 2035 and reach 5.4 million while the activity level stays stable. Annual gasoline consumption of PCs passes 5.8 billion liters and CO2 and PM2.5 emissions elevate by 62% and 76%, respectively, under the business-as-usual scenario. Based on the results, implementation of stricter emission standards cuts 65% of gaseous emissions while promotion of compressed natural gas bi-fuel cars has no benefit in reducing air pollutants emissions. Cutting fuel subsidies is the most effective policy to limit PM2.5 and CO2 emissions, and fuel consumption growth by controlling the activity level of the fleet.

GROWTH MODELS FOR Araucaria angustifolia (BERTOL.) KUNTZE IN DIFFERENT ECOLOGICAL GRADIENTS IN THE STATE OF SANTA CATARINA

The growth of one or more individuals in a forest is variable with the biotic and abiotic conditions of the environment. Therefore, the objective of this article was to obtain the age and growth estimates of Araucaria angustifolia, in different altitude gradients of occurrence of the species, and to identify the culmination points in the basal area. The study covered three areas with Araucaria Forest in Santa Catarina state, considering different altitudes of occurrence of the species. Non-destructive samples were collected from 226 trees, 76, 73 and 77 trees in areas 1, 2 and 3, respectively. Using the time series, diametric growth models were adjusted, allowing to obtain the curves of current annual increment and average annual increment. In area 1, the age range of the samples was 174 years, in area 2, it was 170 years and in area 3, it was 42 years. The average annual increment for areas 1, 2 and 3 were 0.33 cm, 0.51 cm and 1.01 cm, respectively. Araucaria manages to reach a high growth potential when it is in better development conditions (soil, nutrients, light…).Keywords: Araucaria forest. Dendrochronology. Altitude.

Histogenesis of Human Fetal Liver with Special Histochemical and Selective Immunohistochemical Stains

Introduction: The fetal liver cells can differentiate into both hepatocytes and cholangiocytes based on the induction due to clonogenic properties with high growth potential. Understanding liver histogenesis might be helpful in liver and hepatocyte transplantation. Special histochemical and immunohistochemical stains provide better insight into the hepatic cellular architecture, although the literature regarding the same is relatively sparse. Methodology: This study's objective was to document the microscopic structure of the organization of hepatocytes, the appearance of central veins and sinusoids, the formation of the portal triad, and hematopoietic blasts of the liver at various weeks of gestation by using special histochemical and immunohistochemical stains and also to compare our observations with other regions of India and Western countries. Results: It was observed that the central vein and the arrangement of hepatocytes appeared at 14 weeks of gestation. The sinusoids and portal triads were formed at 15 weeks of gestation. The hemopoiesis level in the liver gradually increased from the 14th to 26th week of gestation, after which it decreased. Conclusion: A better understanding of human fetal liver histogenesis will help future research activities in liver transplantation and hepatocyte transplantation from the aborted/stillborn fetal liver from various weeks of gestation.

Calix[4]arene‐Based Sensitizers for Host‐Guest Supramolecular Dyads for Solar Energy Conversion in Photoelectrochemical Cells.

AbstractThe photogeneration of electricity and solar fuels by solar irradiation in photoelectrochemical cells is one of the sectors with the highest growth potential in the decarbonised society. However, the use of different components, in particular photosensitizers and catalysts, can present problems of charge transfer efficiency at the interface, leading to lower final efficiencies. In this work we present novel integrated photosensitizer‐catalyst dyads based on robust and, at the same time, flexible host‐guest non‐covalent interactions through the use of calix[4]arene cavities. Current photogeneration in photoelectrochemical cells showed twice greater efficiency in the integrated calixarene‐based host‐guest dyads compared to the traditional architecture based on the separate photosensitizer‐catalyst pair. Molecular dynamics studies have shown that the enhanced performance originates from an optimization of the distances between the centres of the photosensitizer, catalyst and semiconductor involved in the charge transfer processes, thus allowing a higher final efficiency of the charge photogeneration process.

State‐space model combining local camera data and regional administration data reveals population dynamics of wild boar

AbstractRecent increases in wildlife cause negative impacts on humans through both economic and ecological damage, as well as the spread of pathogens. Understanding the population dynamics of wildlife is crucial to develop effective management strategies. However, it is difficult to estimate accurate and precise population size over large spatial and temporal scales because of the limited data availability. We addressed these issues by first fitting a random encounter and staying time (REST) model based on camera trap data to construct an informative prior distribution for a capture rate parameter in a harvest‐based Bayesian state‐space model. We constructed a Bayesian state‐space model that integrated administration data on the number of captured wild boar with the prior distribution of capture efficiency estimated by camera trap data. The model with informative prior distribution from the REST model successfully estimated population dynamics, whereas the model using only the administration data did not, owing to a lack of parameter convergence. We identified areas where (1) wild boars exhibit a high potential population growth rate and a high carrying capacity, (2) current trapping efforts are effectively suppressing local populations, and (3) trapping reinforcement is required to control populations in the whole region. The model could be used to predict future trends in populations under the assumptions of ongoing trapping pressure. This will help identify spatially explicit trapping efforts to achieve target population levels.

Natural Polymers and Their Processing: Bottlenecks to Overcome Their Limitations in Medical Applications

Natural polymers are widely known and extensively studied, especially for applications involving biomaterials and medical devices. Such a market has a high-growth potential, associated with the increase in people's average lifetime and the crescent concern for health and prevention by the population worldwide. In spite of this, few products within the medical field made from natural polymers are manufactured on large scale and commercialized. This review aims to provoke a reflection on why there is a missing chain link between the study of these materials and their large-scale production. If there are plenty of research papers published about biopolymers, why are they not available in the market? Initially, we present general statistics about the most commonly studied natural polymers and their applications in the medical field. We then review and analyze the three main processes (in our opinion) involving the production of biomaterials: 3D printing, drying, and sterilization. We present a description of the main processing methods, focusing on the major difficulties and bottlenecks that these processes may present during their use and scale-up. Our main conclusion is that more effort and focus are needed from scientists, in particular chemical and material engineers, to integrate material science with unit operations and close the gap between research and industrial production of natural polymers. This way, we can finally bring decades of development in biopolymers to real-life applications.

Mapping carbon emissions of China's domestic air passenger transport: From individual cities to intercity networks

As a significant carbon emission source with high growth potential, the air transport sector plays a crucial role in China's decarbonisation efforts. However, the spatial pattern and evolutionary dynamics of aviation carbon emissions in China have not been thoroughly studied. This study proposed a framework to reveal the spatial characteristics and influencing factors of aviation carbon emissions at the city level. Using data from 2019 to construct the aviation carbon emissions network of China (ACENC), the novelty of the study lies in the subdivision of carbon emissions of air passenger transport into cities and intercity lines in China, which helps to reveal the spatial characteristics of individual cities in the intercity network. Beijing, Shanghai, Shenzhen, Chengdu, and Guangzhou were the cities with the highest carbon emissions, and the routes between these cities caused a significant amount of carbon emissions. >80 % of the total carbon emissions can be attributed to two communities in the network, owing to their large size and strong connections. Correlation analysis indicates that a city's carbon emissions are significantly related to its demographic and economic attributes as well as its connection with other cities, while a city's carbon emission intensity may be influenced by its centrality in the whole network and the structure of the community to which it belongs. Overall, the presented results provide directions for stakeholders and policymakers to regulate carbon emissions from air transportation.

The effect of mandatory IFRS adoption on the value of cash: The case of Canada

AbstractThis paper presents evidence that Canada's 2011 adoption of IFRS improved Canadian firms' access to external financing. We use a matched sample of Canadian and US firms and find that the marginal value of cash decreased significantly in Canadian firms following mandatory IFRS adoption in Canada. The post‐IFRS decrease in the marginal value of cash is most evident for firms that have a larger number of similar firms in non‐Canadian IFRS regimes. This is consistent with IFRS creating a uniform set of accounting standards that lowers the information costs of cross‐border financing. We also find larger IFRS‐related decreases in the value of cash for firms with high growth potential and low availability of internal cash.

Método transversal e longitudinal para descrição da curva de crescimento de coelhos

ABSTRACT Rabbit farming is an activity with high growth potential due to its easy handling, high prolificacy, low polluting impact, and easy adaptability to family farming systems, producing meat of high biological value. Therefore, the aim of this work was to evaluate, using von Bertalanffy's nonlinear model, growth curves of weight as a function of age in ‘Flemish Giant Rabbits’ and ‘New Zealand White’ crossbred rabbits. Two different data collections were used: the longitudinal method and the cross-sectional method. The experiment was carried out at the Federal University of Lavras, located in the municipality of Lavras, Minas Gerais, Brazil, where 10 crossbred rabbits were evaluated, and animals were weighed from 0 to 150 days of age. Both methods proved to be adequate to describe the development of rabbits and the cross-sectional method proved to be an adequate alternative to obtention of growth curves, saving time in data collection and showing consistent estimates.

Low resistivity, p-type, N-Polar GaN achieved by chemical potential control

We report on low resistivity (1.1 Ω cm) in p-type bulk doping of N-polar GaN grown by metalorganic chemical vapor deposition. High nitrogen chemical potential growth, facilitated by high process supersaturation, was instrumental in reducing the incorporation of compensating oxygen as well as nitrogen-vacancy-related point defects. This was confirmed by photoluminescence studies and temperature-dependent Hall effect measurements. The suppressed compensation led to an order of magnitude improvement in p-type conductivity with the room-temperature hole concentration and mobility measuring 6 × 1017 cm−3 and 9 cm2 V−1 s−1, respectively. These results are paramount in the pathway towards N-polar GaN power and optoelectronic devices.

Date Fruits as Raw Material for Vinegar and Non-Alcoholic Fermented Beverages.

Currently, foods and beverages with healthy and functional properties, especially those that claim to prevent chronic diseases, are receiving more and more interest. As a result, numerous foods and beverages have been launched onto the market. Among the products with enhanced properties, vinegar and fermented beverages have a high potential for growth. Date palm fruits are a versatile raw material rich in sugars, dietary fibers, minerals, vitamins, and phenolic compounds; thus, they are widely used for food production, including date juice, jelly, butter, and fermented beverages, such as wine and vinegar. Furthermore, their composition makes them suitable for the formulation of functional foods and beverages. Microbial transformations of date juice include alcoholic fermentation for producing wine as an end-product, or as a substrate for acetic fermentation. Lactic fermentation is also documented for transforming date juice and syrup. However, in terms of acetic acid bacteria, little evidence is available on the exploitation of date juice by acetic and gluconic fermentation for producing beverages. This review provides an overview of date fruit’s composition, the related health benefits for human health, vinegar and date-based fermented non-alcoholic beverages obtained by acetic acid bacteria fermentation.

Enhancement of black and odorous water treatment coupled with accelerated lipid production by microalgae exposed to 12C6+ heavy-ion beam irradiation

In this study, Auxenochlorella protothecoides (AP-CK) was selected due to its reported high growth potential in sterilized black and odorous water (SBOW). In order to improve the resource utilization level of microalgae for wastewater treatment, AP-CK was mutated using 12C6+ heavy-ion beam irradiation, and a high lipid-containing mutant (AP-34#) was isolated and further evaluated to treat original black and odorous water (OBOW). Compared with the wild type, the maximum removal rates of COD, NH4+-N and TP of the mutant increased by 8.12 ± 0.33%, 10.43 ± 0.54% and 11.97 ± 0.16%, respectively, while maximum dissolved oxygen content increased from 0 to 4.36 ± 0.25 mg/L. Besides, the mutant lipid yield increased by 115.87 ± 3.22% over the wild type in OBOW. The fatty acid profile of AP-34# grown in SBOW and OBOW showed higher proportion of saturated fatty acids (C16:0 and C18:0) and valuable polyunsaturated fatty acids (mainly C20:5n3 and C22:6n3) which are more suitable for biodiesel production and value-added products, respectively. This work provides a new perspective on improving the characteristics of microalgae and an innovative approach for resource-based microalgae wastewater treatment through bioremediation of black and odorous water.

Fitting of Orthokeratology in the United States: A Survey of the Current State of Orthokeratology.

The Fitting of Orthokeratology in the United States (FOKUS) survey provides information about the US orthokeratology market. This independent survey is the first to attain detailed assessment of the orthokeratology market. This study aimed to develop and administer a survey to eye care providers in the United States who are managing orthokeratology patients and those who are not, to determine a profile of prescribers, patients, and overall market. The FOKUS survey was administered and distributed online. Outcome measures of the FOKUS survey involved general categories of (1) practice and practitioner profiles, (2) clinical prescribing patterns, (3) patient profile, (4) products and marketing, (5) fees, and (6) market size and growth. The number of eye care providers who are actively fitting and managing orthokeratology patients in the United States is approximately 3000. A total of 545 responded to the survey; 283 reported that they were actively fitting orthokeratology. Furthermore, 68% of respondents prescribed orthokeratology with the intent of managing myopia, 53% monitor axial length, and 61% start orthokeratology patients at 13 years or younger. The mean number of years a patient wears orthokeratology is 7.8 years. A commonly reported complication with orthokeratology is corneal staining. Microbial keratitis is rarely or never seen by 86% of respondents. Of those currently fitting, 56% anticipate growth of orthokeratology fitting over the next 12 months. Of those not currently fitting orthokeratology, 46% plan to start within 2 years. Orthokeratology represents a small but growing segment of the US contact lens market. The number of practitioners actively prescribing and fitting orthokeratology in the United States is approximately 3000 with high potential for growth within the next 2 years. Results of the FOKUS survey are relevant to practitioners currently fitting or considering orthokeratology, manufacturers, educators, and researchers as baseline for future orthokeratology market assessment.
