Plant species diversity and composition in limestone forests of the Vietnamese Cat Ba National Park

Plant species diversity and composition play crucial roles in many ecosystem services and are largely influenced by environmental conditions, as well as natural and/or anthropogenic disturbances. However, our knowledge of the drivers of plant species diversity and composition in the limestone forests of Vietnam, a hotspot of biodiversity, is limited. To fill this knowledge gap, we surveyed plant species in the Cat Ba National Park (CBNP), located on a limestone archipelago. We hypothesised that: (1) topography, accessibility and spatial isolation drive the diversity and composition of plant communities in the CBNP and that (2) isolated areas contribute to high floristic regional diversity by supporting unique species assemblages. We expected high tree species diversity within the tropical limestone forests of the CBNP, but also that: (3) the abundance of non-tree species negatively affects tree regeneration diversity and abundance. Data were obtained from 90 random sample plots (500 m 2 ) and 450 sub-sample plots (25 m 2 ) in three areas was observed in communities growing under harsh site conditions. We conclude that plant species diversity in the CBNP is high, particularly in easily accessible lowland areas where tree species contribute greatly to biodiversity. However, here, non-tree species can even restrict tree regeneration.
Passengers’ Perceptions of Chinese Airlines’ Service Quality: A Mixed Methods Analysis of User-generated Content

ABSTRACT This study examined passengers’ perceptions of the main Chinese airlines’ service quality based on user-generated content (i.e., quantitative ratings and narratives shared online), as well as investigating whether market segmentation can be based on traveler type. Text reviews and the associated ratings of service attributes, overall satisfaction, and intention to recommend were gathered from the Skytrax website for four top Chinese airlines. The research relied on mixed methods, namely, econometric modeling (i.e., multiple and logistic regression) and mixed context analysis. The most influential variable in terms of explaining overall satisfaction and intent to recommend is value for money. Different traveler types are homogeneous in their ratings of the most important attributes, but market segmentation can be based on other variables. The content analysis revealed seven main themes: recommendation, core service, seat comfort, food and beverages, ground service, value for money, and in-flight entertainment. The results contribute to the literature by clarifying service quality attributes’ impacts on intention to recommend and overall satisfaction among different traveler types. Analysis of specific user-generated content segments also provided a deeper understanding of the key concepts passengers use to describe their experiences and of differences according to airline reviewers’ origin (i.e., Western and Eastern).
A Study of Circular Economy Awareness in University Students: The Assessment of Knowledge, Attitude and Behavior

This study explores the university students’ awareness of the Circular Economy (CE) through the identification of knowledge, attitudes and behaviors (KAB). A quantitative method is applied by adopting the SDG survey questionnaire of Cifuentes-Faura that was developed using the 5Rs (Reduce, Reuse, Refurbish, Repair and Recycle) of the CE concept to measure the students’ KAB towards CE. A total of 110 students studying economics-related courses from two Indonesian universities participated in the survey and the statistical program SPSS 20.0 was used for data analysis. The study found that the students’ awareness of the circular economy is higher in terms of knowledge (85.5%) than attitude (55.5%) and behavior (68.2%). In a way, the results of attitude and behavior show that students tend to buy new things instead of reusing/renting or repairing them. The female students' knowledge of CE is higher than male students, whereas their attitude and behaviour show similar results. Additionally, there is a correlation between knowledge and attitude, attitude and behavior, and knowledge and behavior, which means that the variables influence each other.
Repercussions of pathway inhibition response of Panaxginseng fractions ameliorate cardiac dysfunction in hypertensive model rats

This study examined the preventive and therapeutic benefits of various Panax ginseng fractions against NG-nitro-L-arginine methyl ester (L-NAME)-induced hypertension in rats. Rats injected with L-NAME plus vehicle exhibited persistently elevated SBP, serum concentrations of the cardiac injury biomarkers creatine kinase (CK), CK-MB, and troponin, total cholesterol, triglyceride (TG), low-density lipoprotein (LDL), and interleukin (IL)-6, but lower high-density lipoprotein (HDL) compared to the vehicle control group. Furthermore, L-NAME disrupted the normal histological structure and function of rat cardiac tissue. All ginseng fractions and losartan restored SBP to a normal level, reversed the changes in CK, CK-MB, troponin, total cholesterol, TG, HDL, and LDH, and preserved normal myocardial histology, with the WGF demonstrating the greatest cardioprotective and antihypertensive effects. Compounds within multiple ginseng fractions, but especially the aqueous fraction, possess potent and effective antihypertensive, antilipidemic, anti-inflammatory, and cardioprotective properties.
Spheroid's Panchromatic Investigation in Different Environmental Regions (SPIDER) - I. Sample and galaxy parameters in the grizYJHK wavebands

This is the first paper of a series presenting a Spheroid's Panchromatic Investigation in Different Environmental Regions (SPIDER). The sample of spheroids consists of 5,080 bright (Mr<-20) Early-Type galaxies (ETGs), in the redshift range of 0.05 to 0.095, with optical (griz) photometry and spectroscopy from SDSS-DR6 and Near-Infrared (YJHK) photometry from UKIDSS-LAS (DR4). We describe how homogeneous photometric parameters (galaxy colors and structural parameters) are derived using grizYJHK wavebands. We find no systematic steepening of the CM relation when probing the baseline from g-r to g-K, implying that internal color gradients drive most of the mass-metallicity relation in ETGs. As far as structural parameters are concerned we find that the mean effective radius of ETGs smoothly decreases, by ~30%, from g through K, while no significant dependence on waveband is detected for the axis ratio, Sersic index, and a4 parameters. Also, velocity dispersions are re-measured for all the ETGs using STARLIGHT and compared to those obtained by SDSS. We compare our (2DPHOT) measurements of total magnitude, effective radius, and mean surface brightness with those obtained as part of the SDSS pipeline (Photo). Significant differences are found and reported, including comparisons with a third and independent part. A full characterization of the sample completeness in all wavebands is presented, establishing the limits of application of the characteristic parameters presented here for the analysis of the global scaling relations of ETGs.
“I no longer count in German.” On dominance shift in returnee heritage speakers

Abstract This study analyzes the degree of language balance in three groups of bilingual speakers of Portuguese and German: a group of Portuguese heritage speakers (HSs) living in Germany, another who returned to Portugal, and Portuguese late learners of German L2. Based on the DIALANG vocabulary size placement test, applied in German and in Portuguese, and on extralinguistic variables extracted from a background questionnaire, the results confirm high degrees of unbalanced language dominance favoring the societal language (SL) in HSs without the experience of return, and a leveling of language dominance in returnees. Language balance in returnees is the consequence of some loss of proficiency in the former SL (German) and reactivation of the heritage language (Portuguese). Current relative amount of contact with the two languages is correlated with language dominance only in the HSs and the late L2 speaker groups, whereas age of return and length of residence in Portugal explain language dominance in returnees. Self-reported proficiency is also predictive of language dominance and may be taken as complementary indicator.
Zooming in on quasar accretion disks using chromatic microlensing

Observing the temperature profiles of accretion disks around black holes is a fundamental test of an important astrophysical process. However, angular resolution limitations have prevented such a measurement for distant quasars. We present a new method for determining the size of quasar accretion disks at a range of wavelengths, thus constraining their temperature profiles. The technique uses single-epoch, multi-wavelength optical and nearinfrared imaging of gravitationally lensed quasars in conjunction with X-ray imaging, and takes advantage of the presence of microlensing perturbations to the magnifications of the lensed images. The dependence of these perturbations on the angular size of the source, combined with the temperature structure of quasar accretion disks, causes the flux ratio anomalies due to microlensing to appear chromatic. This allows us to probe regions of the quasar that are too small to be measured by any other technique. We apply this method to observations of 12 lensed quasars, and measure the size of the accretion disk of each in 8 broadband filters between 0.36 and 2.2 microns (in the observed frame). We find that the overall sizes are larger by factors of 3 to 30 than predicted by the standard thin accretion disk model, and that the logarithmic slope of the wavelength-dependent size is ~ 0.2 on average, much shallower than the predicted slope of 4/3. This implies that the temperature is a steeper function of radius than the thin disk model predicts. With this new approach to determining quasar accretion disk sizes, we are thus able to rule out the standard thin disk model as the source of the (rest-frame) ultraviolet and optical continuum in these bright quasars.

Exploring Oral Microbiome in Healthy Infants and Children: A Systematic Review

Recent advances in the development of next-generation sequencing (NGS) technologies, such as the 16S rRNA gene sequencing, have enabled significant progress in characterizing the architecture of the oral microbiome. Understanding the taxonomic and functional components of the oral microbiome, especially during early childhood development, is becoming critical for identifying the interactions and adaptations of bacterial communities to dynamic conditions that may lead to the dysfunction of the host environment, thereby contributing to the onset and/or progression of a wide range of pathological conditions. We aimed to provide a comprehensive overview of the most recent evidence from studies of the oral microbiome of infants and young children, focusing on the development of oral microbiome in the window of birth to 18 years, focusing on infants. A systematic literature search was conducted in PubMed, Scopus, WOS, and the WHO clinical trial website for relevant articles published between 2006 to 2022 to identify studies that examined genome-wide transcriptome of the oral microbiome in birth, early childhood, and adolescence performed via 16s rRNA sequence analysis. In addition, the references of selected articles were screened for other relevant studies. This systematic review was performed in accordance PRISMA guidelines. Data extraction and quality assessment were independently conducted by two authors, and a third author resolved discrepancies. Overall, 34 studies were included in this systematic review. Due to a considerable heterogeneity in study population, design, and outcome measures, a formal meta-analysis was not carried out. The current evidence indicates that a core microbiome is present in newborns, and it is stable in species number. Disparity about delivery mode influence are found. Further investigations are needed.
Spanning Trees With Leaves Bounded By Independence Number

In [2], Rahman and Kaykobad present an algorithm to construct a spanning tree with degree bounded by independence number. In this paper, we prove that every connected graph G has a spanning tree with at most (G)((G) 2) leaves (where (G) denotes the independence number of G), which yields an algorithm to obtain a spanning tree with not only degree but also leaves bounded by independence number. The graphs considered in this paper are finite, undirected, and simple (no loops or multiple edges). The sets of vertices and edges of a graph G are denoted by V (G) and E(G), respectively. We denote the maximum degree of vertices of G by (G). A connected acyclic graph is called a tree. A vertex with degree one in a tree is called a leaf. A vertex with degree at least 3 in a tree is called a branch vertex . I fT is a tree, we denote the set of all leaves of T by L(T). If vertices u and v are connected in G, the distance between u and v in G, denoted by dG(u,v), is the length of a shortest (u,v)-path in G; if there is no path connecting u and v we define dG(u,v) to be infinite. Let C be a cycle and x,y,z be dierent vertices in C, we denote the path from x to z passing through y on C by C[x,y,z]. For terminology and notation not defined in this paper the reader is referred to [1]. Rahman and Kaykobad proved the following theorem in [2]. THEOREM 1. Every connected graph has a spanning tree with degree bounded by its independence number. Furthermore, the corresponding spanning tree can be computed in O(n 2 ) worst case time where n is the number of vertices of the graph. In this paper, we present a similar result like THEOREM 1. In particular, we prove the existence of spanning trees in every connected graph with number of leaves bounded by the independence number. We also prove that existence of spanning tree with bounded number of leaves would imply the existence of spanning tree with bounded degrees. In this sense, our result is stronger than that of [2]. Finally we devise an algorithm to find the corresponding spanning tree. We first prove the core theorem of this paper.
Chest Drainage Therapy: What Comes out of Pandora’s Box Can Affect Patient Outcomes

Background: Over the last 100 years, the original three-bottle chest drainage system has been variously engineered into compact disposables and electronic units. Clinicians are now surrounded by a plethora of different types of systems, but little is known about the way that they work and perform. Thus, we sought to test the performance of the most commonly used chest drainage units under conditions that are relevant to clinical practice. Methods: A pleural space environment simulator was built. Thirty-two units were tested under four clinical scenarios: air leak interpretation during quiet breathing and after obstructed inspiration (−5 to −150 cmH2O), a buildup of negative pressure (−100 cmH2O), a bronchopleural fistula (10 L/min) and the need for effective external suction in the presence of air leakage. Twenty-five units were “traditional” thoracic drainages, five were “digital” low-flow/low-vacuum pumps and two were hybrids (a combination of the two). According to the design of the seal and of the suction control, the units were classified as wet-wet, wet-dry and dry-dry. Results: All wet units showed reverse air flow, with the potential to mimic an air leak when there was none. Ten wet units showed no automatic negative pressure relief features, while five dry-dry did but were slow to react. Ten wet and five dry-dry units showed no capability to handle a 10 L/min leak, as they were restrictive to flow (peak pressure up to 55 cmH2O). Only seven dry-suction units were able to maintain the set suction at high airflow rates (>20 L/min). Conclusions: Different chest drainage unit designs lead to different performances, some of which may negatively impact patient outcomes. This sounds the call to tailor our clinical practice for the individual patient. A paradigm shift to better understand all components of pleural physiology post-surgical intervention on this relatively neglected topic is needed to improve our daily practice.
Remodeling of the Neurovascular Unit Following Cerebral Ischemia and Hemorrhage

Formulated as a group effort of the stroke community, the transforming concept of the neurovascular unit (NVU) depicts the structural and functional relationship between brain cells and the vascular structure. Composed of both neural and vascular elements, the NVU forms the blood–brain barrier that regulates cerebral blood flow to meet the oxygen demand of the brain in normal physiology and maintain brain homeostasis. Conversely, the dysregulation and dysfunction of the NVU is an essential pathological feature that underlies neurological disorders spanning from chronic neurodegeneration to acute cerebrovascular events such as ischemic stroke and cerebral hemorrhage, which were the focus of this review. We also discussed how common vascular risk factors of stroke predispose the NVU to pathological changes. We synthesized existing literature and first provided an overview of the basic structure and function of NVU, followed by knowledge of how these components remodel in response to ischemic stroke and brain hemorrhage. A greater understanding of the NVU dysfunction and remodeling will enable the design of targeted therapies and provide a valuable foundation for relevant research in this area.
Detecting Financial Statement Fraud Using Fraud Triangle and Board of Director’s Attributes Analyses

This study examines whether fraud triangle and board of director’s attributes analyses can detect financial statement fraud in Indonesian listed companies. Financial statement fraud is proxied by Dechow ‘s fraud score model. The fraud triangle analysis includes financial stability, effective monitoring, and rationalization whereas the board of director’s attributes analysis covers number of independent board and board of director’s gender diversity. The unit of analysis is companies listed in KOMPAS100, an index that comprises 100 companies listed in the Indonesian Stock Exchange that have sound liquidity and large market capitalization. The period of the study is 2016 to 2019. The results of the study show that neither of the three aspects fraud triangle nor the two aspects of the board of director’s attributes analysis can detect the financial statement fraud. Such results evidence the extent to which large and liquid Indonesian listed companies have fairly reported their financial statements.
Diagnosing Scale-Dependent Energy Cycles in a High-Resolution Isopycnal Ocean Model

Energy exchanges between large-scale ocean currents and mesoscale eddies play an important role in setting the large-scale ocean circulation but are not fully captured in models. To better understand and quantify the ocean energy cycle, we apply along-isopycnal spatial filtering to output from an isopycnal 1/32° primitive equation model with idealized Atlantic and Southern Ocean geometry and topography. We diagnose the energy cycle in two frameworks: (1) a non-thickness-weighted framework, resulting in a Lorenz-like energy cycle, and (2) a thickness-weighted framework, resulting in the Bleck energy cycle. This paper shows that (2) is the more useful framework for studying energy pathways when an isopycnal average is used. Next, we investigate the Bleck cycle as a function of filter scale. Baroclinic conversion generates mesoscale eddy kinetic energy over a wide range of scales, and peaks near the deformation scale at high latitudes, but below the deformation scale at low latitudes. Away from topography, an inverse cascade transfers kinetic energy from the mesoscales to larger scales. The upscale energy transfer peaks near the energy-containing scale at high latitudes, but below the deformation scale at low latitudes. Regions downstream of topography are characterized by a downscale kinetic energy transfer, in which mesoscale eddies are generated through barotropic instability. The scale-and flow-dependent energy pathways diagnosed in this paper provide a basis for evaluating and developing scale- and flow-aware mesoscale eddy parameterizations.
CONSOLIDATING AND CRUSHING EXOPLANETS: DID IT HAPPEN HERE?

The Kepler mission results indicate that systems of tightly packed inner planets (STIPs) are present around of order 5% of FGK field stars (whose median age is ∼5 Gyr). We propose that STIPs initially surrounded nearly all such stars, and those observed are the final survivors of a process in which long-term metastability eventually ceases and the systems proceed to collisional consolidation or destruction, losing roughly equal fractions of systems every decade in time. In this context, we also propose that our solar system initially contained additional large planets interior to the current orbit of Venus, which survived in a metastable dynamical configuration for 1%–10% of the solar system’s age. Long-term gravitational perturbations caused the system orbits to cross, leading to a cataclysmic event that left Mercury as the sole surviving relic.
Earlier and more frequent occupation of breeding sites during the non‐breeding season increases breeding success in a colonial seabird

Abstract Competition for high‐quality breeding sites in colonial species is often intense, such that individuals may invest considerable time in site occupancy even outside the breeding season. The site defense hypothesis predicts that high‐quality sites will be occupied earlier and more frequently, consequently those sites will benefit from earlier and more successful breeding. However, few studies relate non‐breeding season occupancy to subsequent breeding performance limiting our understanding of the potential life‐history benefits of this behavior. Here, we test how site occupancy in the non‐breeding season related to site quality, breeding timing, and breeding success in a population of common guillemots Uria aalge, an abundant and well‐studied colonially breeding seabird. Using time‐lapse photography, we recorded occupancy at breeding sites from October to March over three consecutive non‐breeding seasons. We then monitored the successive breeding timing (lay date) and breeding success at each site. On average, sites were first occupied on the 27th October ± 11.7 days (mean ± SD), subsequently occupied on 46 ± 18% of survey days and for 55 ± 15% of the time when at least one site was occupied. Higher‐quality sites, sites with higher average historic breeding success, were occupied earlier, more frequently and for longer daily durations thereafter. Laying was earlier at sites that were occupied more frequently and sites occupied earlier were more successful, supporting the site defense hypothesis. A path analysis showed that the return date had a greater or equal effect on breeding success as lay date. Pair level occupancy had no effect on breeding timing or success. The clear effect of non‐breeding occupancy of breeding sites on breeding timing and success highlights the benefits of this behavior on demography in this population and the importance of access to breeding sites outside the breeding season in systems where competition for high‐quality sites is intense.
