Unicorns Gallop Rampant Through China And India: Successes And Similarities

This study aims to explore the success and characteristics of the novel business model used by Chinese and Indian unicorn firms as well as attempts to develop a framework called CEHI (Collocation, Entrepreneurship Attitudes, High Tech Startups, and Innovation) for the analysis of global unicorn firms. The literature on unicorn firms is immature in business, management, and accounting (BMA) literature found in Scopus and Web of Science. To bridge this gap, this paper performs a holistic review of the existing literature, exploring and analyzing all unicorns in China and India (referred to collectively as Chindia) (89 Chinese Unicorns and 16 Indian Unicorns as of 2019) to provide insights into the phenomenon and contribute towards future avenues for research into unicorns.
Mating System and Genetic Variability of the Endangered Endemic Aquatic Lycophyte, Isoëtes yunguiensis, in China Determined using AFLP Markers

Abstract. — In this study, mating system, genetic diversity, and genetic structure of the endangered endemic aquatic lycophyte Isoëtes yunguiensis in China was investigated using AFLP markers. The estimates of outcrossing rates (tm = 1.200) indicate that diploid I. yunguiensis is a predominantly outcrossing species. Six selected AFLP primer pairs used in the study amplified 195 reproducible bands, 160 of which were polymorphic (PPB = 82.05%), indicating significant genetic diversity at the species level. AMOVA revealed that 40.12% of the genetic variation was attributable to differences between populations and the rest (59.88%) to variability within populations. High outcrossing rates and the historical accumulation of genetic variation may be responsible for the high levels of genetic diversity observed in the I. yunguiensis population. To maintain the current level of genetic diversity for this species, we recommend increasing in situ conservation sites.
New data on the winged fruits of Carpolithus prangosoides Berry from the Eocene of western Tennessee and Kentucky.

We reexamined the morphology of the winged fruits Carpolithus prangosoides Berry (later synonym: Terminalia vera Berry) from the Eocene Claiborne Formation of southeastern North America, based on original and more recently collected specimens from several localities in Tennessee and Kentucky, USA. Physical and virtual sections of the fossils allow for more detailed documentation of wing morphology. The fruits are ellipsoidal, with five main lateral wings which bear radiating reticulate venation that forms loops near the margin. None of the fruits show pedicel or style remnants, but a basal pedicel scar was observed at the end opposite to the prominent, persistent sepals, indicating that the perianth was epigynous. A comparison with all known families having fin-winged fruits was conducted to assess possible affinities of C. prangosoides. Although no modern genus was found to match these fossils, the available characters, including the five sepals, suggest that it belongs to the Eudicot clade, likely in the Pentapetalae. However, the prior suggestion of combretaceous affinity is rejected based on differences in wing number and venation. We reviewed other North American reports of combretaceous fossils, concluding that only a few of them are reliable records for the family.
Safety and efficacy of transitioning from the combination of bosentan and sildenafil to alternative therapy in patients with pulmonary arterial hypertension

The combination of bosentan and sildenafil is commonly used to treat patients with pulmonary arterial hypertension (PAH); however, there is evidence of a significant drug interaction between these two medications. We sought to evaluate the safety and efficacy of transitioning patients with PAH from the combination of bosentan and sildenafil to alternative therapy. A retrospective database review was performed on 16 patients with PAH who were treated with the combination of bosentan and sildenafil and transitioned to alternative treatment at our center. Invasive and non-invasive patient parameters were collected at baseline and after transition. 56.3% of patients were in World Health Organization functional class (WHO FC) III and a majority of patients (68.7%) were on background prostacyclin therapy. The most common reason for transition was concern for a drug interaction in seven patients (43.8%). The most common transition was bosentan to macitentan in eight patients (50%). Fifteen patients (93.8%) tolerated the transition after a median follow-up of 6.5 months with minor adverse events occurring in four patients (25%). In 11 patients, 6-min walk distance (6MWD) was unchanged comparing baseline to post transition measurements with a median change of +8 m (range: −50 to + 70; P = 0.39). Nine patients (81.8%) had stable (within 15% margin) or significant improvement (increase by ≥15%) in 6MWD after transition. All patients demonstrated stable or improved WHO FC after transition. There were no significant changes after transition in hemodynamics, N-terminal pro-brain natriuretic peptide (NT-proBNP) values, or Registry to Evaluate Early and Long-Term PAH Disease Management (REVEAL) risk scores. In our study, transitioning patients from bosentan and sildenafil to alternative therapy was safe and resulted in clinical stability.
Evaluation of the mechanical and release properties of lactose and microcrystalline cellulose and their binary mixtures as directly compressible excipients in paracetamol tablets.

Binary mixtures of microcrystalline cellulose MCC (A), and lactose (L) in ratios at 75:25, 50:50, and 25:75% respectively were prepared. The binary mixtures were subjected to microscopical analysis and density measurements. The mechanical properties of paracetamol tablets formulated with the above excipients were assessed for tensile strength, bonding capacity (using the Ryshkewitch-Duckworth relation) and friability, while drug release properties were assessed for disintegration and dissolution times. The dissolution profiles were fitted into dissolution model equations to determine release mechanism and similarity of release. Microscopic analysis showed that the lactose particles were large, crystalline, and acicular in shape whereas the MCC particles were smaller and irregularly shaped. The binary mixtures had particle shape and sizes in between the parent compounds. The particle size of A25:L75 however, was larger than that of the proprietary brand, Microcelac®. Bulk and tapped densities increased with increasing amounts of MCC in the binary mixtures while particle density had an inverse relationship. Tablets containing A75:L25 had the highest tensile strength and bonding capacity and lowest friability in comparison to other binary mixtures and Microcelac ® . However, tablets containing A75:L25 did not show superiority to Microcelac ® in terms of paracetamol release. Its release, however, followed the Korsmeyer-Peppas model indicating a super case II transport mechanism. Only comparisons of tablet combinations of Lactose: A25:L75 and MCC: A50:L50 had a similarity factor, f2 >50. Tablets made of A75:L25 exhibited the highest mechanical and release properties of the binary mixtures, as directly compressible excipient in comparison to the parent compounds and Microcelac®. This mixture, A75:L25 therefore, could be developed for commercial use in tablet formulations.
Real vs. Immersive Virtual Emotional Museum Experience: a Heart Rate Variability Analysis during a Free Exploration Task

We investigated the autonomic nervous system activity of 60 participants during a free exploration of a real museum and its virtualization viewed through a head mounted display. We analyzed differences in heart rate variability features defined in the time and frequency domains between virtual and real stimuli associated with two levels of emotional arousal, high and low. The results showed sympathovagal changes during the real museum exploration, but no differences were found in the virtual scenario. The findings contribute to the understanding of the use of virtual reality scenarios in emotion research.
Climate‐Driven Weathering Shifts Between Highlands and Floodplains

Chemical weathering of silicate rocks on continents is thought to have played an important role in the evolution of past atmospheric carbon dioxide over geologic timescales. However, the detailed links between continental weathering and climate change over shorter timescales, and their potential impact on sediment records deposited in the ocean, remain poorly understood. Here, we present clay mineralogy and strontium‐neodymium isotopic data for marine sediment records from the Northern Indian Ocean, with the aim of investigating the weathering response of large Himalayan river basins to orbital and millennial climate forcing. We show that past glaciated episodes of the late Quaternary corresponded to periods of increased physical erosion, associated with the preferential export of illite and chlorite assemblages from the Himalayan highlands having relatively radiogenic Sr isotopic signatures. In contrast, the warm periods of enhanced monsoon rainfall coincided with the transport of intensively weathered smectite‐dominated soils derived from the floodplains, characterized by lower 87Sr/86Sr signatures. This finding suggests that the short‐term climatic variability over late Quaternary timescales was accompanied by concomitant changes between high mountain‐ versus floodplain‐dominated weathering regimes, with possible impact on the nature of weathered rocks and, as a consequence, on the carbon cycle.
The Effect of Innovation-oriented Organizational Culture on Job Engagement and Job Stress: Focusing on Moderating Effect of Selfefficacy

Purpose: The purpose of this study is, in the situation where rapid response to the rapidly changing environment is required due to the development of the fourth industrial revolution such as artificial intelligence, virtual reality, and the internet of things, robotics, big data, additive manufacturing, bio-health, sharing economy and in the organizational culture aspiring toward the innovation of a major company, small business and a public institution, to analyze what influence a job-engagement and stress make, and what influence individual‟s self-efficacy as a moderator mediator makes, and to offer basic data for improving job-engagement and lowering job-stress. Research design, data, and methodology: For doing this, the literature and the empirical studies were combined. Deriving innovationoriented organizational culture as factors affecting the job engagement and job stress through the literature, and have established hypotheses to verify them. We have collected data of 281 from ex,ecutives and staff-members working in areas including major company, small business and officials (the central government, a local public service, the prosecution, the police, and school). And these data were analyzed by SPSS 23 version. Results: Based on these data, the results of analysis were as follows; First, the innovationoriented organizational culture which was recognized by organizational members had effect on job-stress. Second, the innovationoriented organizational culture which was recognized by organizational members influenced job-stress. Third, in the relationship between the innovation-oriented organizational culture and job-engagement, self-efficacy did not influenced job-engagement. Finally, in the relationship between the innovation-oriented organizational culture and job-stress, self-efficacy influenced job-stress. Conclusions: Innovation-oriented organizational culture places importance on the organization's adaptability and flexibility in the external environment, so companies need to establish an innovation-oriented organizational culture favorable to achieving survival and successful innovation, and to develop and disseminate programs of positive and continuous organizations to improve task enthusiasm, reduce task stress, and enhance organizational performance. In the future, it will be necessary to verify the effectiveness of various organizational culture types through comparative analysis with companies that actively maintain an innovation-oriented organizational culture (Google, Kakao, etc.) and companies that prefer hierarchy-oriented organizational culture, relationship-oriented organizational culture, and market-oriented organizational culture.
Ocular Biometrics Recognition by Analyzing Human Exploration during Video Observations

Soft biometrics provide information about the individual but without the distinctiveness and permanence able to discriminate between any two individuals. Since the gaze represents one of the most investigated human traits , works evaluating the feasibility of considering it as a possible additional soft biometric trait have been recently appeared in the literature. Unfortunately, there is a lack of systematic studies on clinically approved stimuli to provide evidence of the correlation between exploratory paths and individual identities in “natural” scenarios (without calibration, imposed constraints, wearable tools). To overcome these drawbacks, this paper analyzes gaze patterns by using a computer vision based pipeline in order to prove the correlation between visual exploration and user identity. This correlation is robustly computed in a free exploration scenario, not biased by wearable devices nor constrained to a prior personalized calibration. Provided stimuli have been designed by clinical experts and then they allow better analysis of human exploration behaviors. In addition, the paper introduces a novel public dataset that provides, for the first time, images framing the faces of the involved subjects instead of only their gaze tracks.

The design used in this study is true experimental design using pretest - posttest control group design. The experimental group and the control group were given the pretest. Then the experimental group was given the treatment. After that, a posttest was carried out on the experimental group and the control group. Data was collected by documentation, observation and questionnaire described according to the findings. Data analysis techniques in this study used an independent sample t-test. The results of this study were indicated a significant increase in students’ interest in entrepreneurship in the experimental class given treatment using the GEPPRAK learning model. This is evidenced by testing used the t-test and obtained the significance of the average difference test post-test Sig (2- tailed ) 0.017 t table (1.980). Therefore, the decision test H 0 rejected means that there are differences in the average scores post-test of students in the experimental class and the control class. The difference in the average scores post-test of students explains that treatment in the experimental class can increase students’ entrepreneurial interest.
Improving the classification of neuropsychiatric conditions using gene ontology terms as features

Although neuropsychiatric disorders have a well-established genetic background, their specific molecular foundations remain elusive. This has prompted many investigators to design studies that identify explanatory biomarkers, and then use these biomarkers to predict clinical outcomes. One approach involves using machine learning algorithms to classify patients based on blood mRNA expression from high-throughput transcriptomic assays. However, these endeavours typically fail to achieve the high level of performance, stability, and generalizability required for clinical translation. Moreover, these classifiers can lack interpretability because informative genes do not necessarily have relevance to researchers. For this study, we hypothesized that annotation-based classifiers can improve classification performance, stability, generalizability, and interpretability. To this end, we evaluated the performance of four classification algorithms on six neuropsychiatric data sets using four annotation databases. Our results suggest that the Gene Ontology Biological Process database can transform gene expression into an annotation-based feature space that improves the performance and stability of blood-based classifiers for neuropsychiatric conditions. We also show how annotation features can improve the interpretability of classifiers: since annotation databases are often used to assign biological importance to genes, annotation-based classifiers are easy to interpret because the biological importance of the features are the features themselves. We found that using annotations as features improves the performance and stability of classifiers. We also noted that the top ranked annotations tend contain the top ranked genes, suggesting that the most predictive annotations are a superset of the most predictive genes. Based on this, and the fact that annotations are used routinely to assign biological importance to genetic data, we recommend transforming gene-level expression into annotation-level expression prior to the classification of neuropsychiatric conditions.
Cu-Based Thermoelectrochemical Cells for Direct Conversion of Low-Grade Waste Heat into Electricity

A hurdle to the commercialization of thermoelectrochemical cells (TECs) based on the redox reaction of hexacyanoferrate (HCF) to convert low-grade waste heat into electricity is the high manufacturing cost resulting from the noble electrode materials like Pt and nanostructured carbon. Herein, we report the successful exploitation of low-cost Cu, which has not been considered ever for the TEC electrode material because of its heavy corrosion in the operating condition. Interestingly, we found that by precisely tuning the pH of the electrolyte-containing HCF to the immunity window, Cu was applicable to a TEC electrode, showing a performance closely equal to Pt and superior to carbon materials with negligible corrosion. Cu-based TECs can achieve a commercially viable module cost of $0.19 W–1, which far exceeds the general cost target for thermoelectric devices (∼$1 W–1) and is even more competitive than that for commercial solar power (∼$0.4 W–1).
