Spatially explicit assessment of genetic variation to inform conservation effort for an endangered Mediterranean conifer, Cedrus atlantica

Abstract Preserving the genetic diversity of forest species is critical for maintaining their adaptive potential and allowing for generation turnover in forest ecosystems. Considering an uncertain future, it is necessary to establish reliable genetic conservation strategies to optimize the genetic variation preserved within populations in a spatially explicit context to assist decision‐makers. Hence, we aimed to incorporate genetic information into spatially designed conservation actions. Cedrus atlantica is a large, long‐lived conifer native to the mountains of North Africa, threatened by extinction. The relevant genetic units for conservation were selected using Bayesian analysis. The relative contribution of the populations to the genetic pool that maximized the species' genetic diversity was calculated to design an optimal seed bank. Finally, the relationship between the genetic composition and bioclimatic variables was estimated and projected throughout the study area under current and future climatic conditions. Three relevant genetic units were found for C. atlantica conservation that maximizes genetic diversity in a spatial context. Bioclimatic variables with the highest influence on genetic composition were closely related to climate warming and decreased soil water availability. We identified the role of genetic markers in designing a reliable conservation strategy for forest trees considering climate change, increased deforestation, and aridity. Projections of genetic composition due to the climate in the study region of North Africa provide spatially explicit guidance for optimizing the selection and preservation of seed banks.

Could Maternal Vitamin D Concentration Affect Cervical Length in Mid-Pregnancy? A Report From an Iranian Tertiary Center

Objective: This descriptive-analytic cross-sectional study aimed to figure out whether maternal serum vitamin D concentration correlates with cervical length measurement in mid-gestation or not. Materials and methods: During Jun-Jan 2021, 213 pregnant women at 18–22 weeks of gestation were investigated. First, demographic features were obtained then, maternal serum vitamin D concentration was measured by enzyme-linked immunoassay and cervical length was measured via transvaginal sonography according to fetal maternal foundation guideline and appropriate statistical test was used to analyze the correlation between maternal vitamin D level and cervical length in mid-pregnancy. Results: It was shown that 29.6% and 25.4% of participants had vitamin D deficiency and insufficiency, respectively. Spearman’s test found no significant correlation between maternal vitamin D level and cervical length in mid-pregnancy. Moreover, cervical length and maternal vitamin D level had no association with maternal BMI. Conclusion: Although maternal vitamin D level and its sufficiency status was not associated with cervical length in mid-pregnancy, as a trend toward decreased maternal serum vitamin D level by advancing gestational age was observed. It may be concluded that it is prolonged vitamin D deficiency during gestation that may lead to cervical length shortening and subsequent preterm delivery later in gestation.
Experimental Investigation of the Effect of Tube-to-Tube Porous Medium Interconnectors on the Thermohydraulics of Confined Tube Banks

This experimental study investigates the effect of tube-to-tube copper porous interconnectors on the thermohydraulic performance of an in-line and staggered confined tube bank. The porous medium, having a transverse thickness equal to that of the diameter of the tube (9 mm), connects longitudinally six successive tubes kept as in-line and staggered arrangements with a square pitch of 2.0. The tubes are subjected to a constant and uniform heat flux and are cooled by forced convection under laminar-transition flow range (200 < Reynolds number < 1500) using air with a Prandtl number of 0.71 as cooling fluid. Experimental data presented here establish that by introducing tube-to-tube porous medium interconnectors for the maximum Reynolds number tested here, a reduction in the pressure drop by 18% is observed in the in-line configuration while the heat transfer is enhanced by 100% in the staggered configuration, when compared to their respective configurations without the porous medium. Defining an overall energy gain as the ratio of the heat transfer enhancement due to the presence of the porous inserts to the pressure drop incurred, it is seen that fixing the porous inserts in the in-line configuration is advantageous.
Customer-Defined Market Orientation, Brand Image and Customer Satisfaction: A Mediation Approach

Over the past two decades, marketing literature has classified market orientation’s nature, antecedents, and consequences as intra-organizational phenomena. Most studies focus on market orientation at the organizational level, concentrating on managers’ views of their companies. Another school of thought contends that customer perception of company offerings is critical. This research provides empirical data on the effect of a customer-defined market orientation on consumer satisfaction, with brand image functioning as a mediator. The study focused on South Asian ethnic restaurants in Malaysia. Data was collected from 301 respondents and analyzed using the PLS-SEM technique. Results reveal that customer-defined market orientation has a positive impact on consumer satisfaction. Furthermore, brand image mediated the link between customer-defined market orientation and customer satisfaction to a lesser extent. Finally, researchers addressed managerial implications, limitations, and future directions.
Optimum lyapunov functions and stability regions for multimachine power systems

The paper is a contribution to the application of Lyapunov's theory to the analysis of transient power-system stability. The technique of the paper originates with a theorem introduced by Anderson to prove the generalised Popov criterion for multivaiable fedback systems. Explicit expressions of the Lyapunov functions and the transient-stability regions are computed for multimachine power systems. It is shown that the obtained Lyapunov functions yield better estimates of the stability regions than the energy function which was used in some recent papers. The dependence of the stability regions on the damping torques is investigated. It is shown that optimum-stability results are obtained if particular relationships between damping torques and inertial constants are satisfied.
Investments in Bonds, Stocks, Gold and Real Estate as a Hedge Against Inflation

In times of accelerating inflation, financial instruments that protect capital against loss of value are becoming increasingly important. Therefore, an open question remains as to what to invest in to, if not outstrip, at least keep up with the inflation rate in the case of return on investments. This raises the question of whether there are such opportunities in the market. However, according to some authors, this type of analysis is not easy and simple econometric methods are not able to show the appropriate dependencies. An example is real estate investment, which, especially in the short term, may not be a suitable inflation hedge. The purpose of the study is to determine whether investments in the Polish capital market are able to protect capital from depreciation due to inflation. The study began with the analysis of distributions, stationarity of returns and correlation of successive investments and the CPI inflation rate, ending with cointegration analysis using the Engle‑Granger test. The analysis was performed from the first quarter of 2009 to the fourth quarter of 2021. The following indices were used for the study: the TBSPIndex from the bond market, the WIG from the stock market, gold prices in PLN, the NBP hedonic index of real estate prices in seven largest Polish cities and CPI inflation rates published by Statistics Poland (GUS). The analysis led to a negative verification of the research hypothesis, as it could not be proved that the analysed indices and prices are related to the level of inflation. The study fills a gap in the Polish market for analysis of capital protection against inflation. The research concerns only the Polish market, however this issue has not been discussed for years in mature economies either.
Nutrition claims influence expectations about food attributes, attenuate activity in reward‐associated brain regions during tasting, but do not impact pleasantness

Nutrition claims are one of the most common tools used to improve food decisions. Previous research has shown that nutrition claims impact expectations; however, their effects on perceived pleasantness, valuation, and their neural correlates are not well understood. These claims may have both intended and unintended effects on food perception and valuation, which may compromise their effect on food decisions.
Magnetorotational iron core collapse

During its final evolutionary stages, a massive star, as considered in current astrophysical theory, undergoes rapid collapse, thereby triggering a sequence of a catastrophic event which results in a Type II supernova explosion. A remnant neutron star or a black hole is left after the explosion. Stellar collapse occurs, when thermonuclear fusion has consumed the lighter elements present. At this stage, the core consists of iron. Difficulties arise regarding an appropriate model with respect to the core collapse. The present investigation is concerned with the evolution of a Type II supernova core including the effects of rotation and magnetic fields. A simple neutrino model is developed which reproduced the spherically symmetric results of Bowers and Wilson (1982). Several two-dimensional computational models of stellar collapse are studied, taking into account a case in which a 15 solar masses iron core was artificially given rotational and magnetic energy.
The chemical composition and evolutionary state of the early R stars.

A sample of 11 stars classified R0-R5 has been analyzed to determine (i) iron-peak metal abundances, (ii) abundances of elements produced by the s-process, (iii) the light element abundances (C,N, and O), and (iv)= the carbon isotopic ratio /sup 12/C//sup 13/C. Abundances are reported relative to the Sun. With the expection of HD 100764, which has an iron abundance 0.6 dex lower than the Sun's, the iron abundance of 10 stars is near solar. The s-process elements have no demonstrable enhancement in the sample, unlike the Ba II stars of the same temperature and the cooler carbon stars. The enhancement of carbon relative to the G-K giants found in the analysis of eight stars is 0.7 dex, with one star having Croughly-equal O (HD 113801), while another star (HD 95405) is probably not a carbon star (C/O = 0.87). Relative to the ordinary G-K giants, nitrogen is enhanced by a small amount (0.2 dex). In contrast, oxygen has nearly the value found in the Sun and in normal giants, except in the case of HD 100764 where O is probably as underabundant as Fe. The /sup 12/C//sup 13/C ratio ranges for near 4 to 14 for nine stars, indicating anmore » enrichment of /sup 13/C with respect to the majority of faint giants. For HD 156074 the oxygen isotopic ratios /sup 16/O//sup 17/O and /sup 16/O//sup 18/O do not have detectable departures from the solar system values. The lack of oxygen depletion indicates that the CNO cycle operating near equilibrium is not responsible for the fact that C/O>1 in these stars. Based on the early R stars' position in the H-R diagram, their space number densities, and their enhanced carbon abundances, it is here suggested that they result from mixing at the time of, or closely following, the helium core flash. « less
Wave Attenuation in Saturated Sediments

This paper considers a mathematical model to describe the propagation of low‐amplitude waves in saturated sediments. Losses due to inelasticity of the skeletal frame and to motion of the pore fluid relative to the frame are both accounted for, and each is found to be significant in a different frequency range. The theory shows favorable agreement with experimental results where available for both sands and finer‐grained sediments over a wide range of frequencies.
Utility of first lactation fat energy corrected milk yield as a trait for genetic evaluation of Mehsana buffalo bulls using various sire evaluation methods

India being a vegetarian country, milk is the major source of dietary bio-energy, but majority of animals are routinely being evaluated on the basis of their milk producing ability. The present study was aimed to come up with a sire evaluation methodology based on first lactation Fat Energy Corrected Milk Yield (FBE) in order to obtain an accurate and unbiased estimate of breeding value of Mehsana buffalo bulls and ranking them on the basis of their daughter's performance for future herd improvement. Data for the present study included 7825 she buffaloes in their first lactations, extended over a period of 25 years (1989 to 2013), from field progeny testing programme of Dudhsagar Research and Development Association (DURDA), Dudhsagar Dairy, Mehsana, Gujarat. The data were classified into different subclasses based on period, season, cluster and age at first calving group. The average breeding values of Mehsana buffalo bulls evaluated for FBE by least squares method (LSM), best linear unbiased prediction sire model (BLUP-SM) and best linear unbiased prediction animal model (BLUP-AM) methods were 1215.89, 1185.7 and 1185.7 kcal, respectively. BLUP-AM method had lowest error variance as compared to LSM and BLUP-SM methods of sire evaluation. This indicated that BLUP-AM was most efficient method.
INFLUENCE OF CARBON EMISSION DISCLOSURE ON FIRM VALUE OF INDUSTRIAL FIRMS IN INDONESIA

The purpose of this research is to analyze the effect of carbon emission disclosure, environmental performance and environmental cost on Firm Value. This research uses 40 firms as sample from 50 industrial sector firms listed on Indonesian Stock Exchange in 2019-2020 as population. Samples are determined by purposive sampling. This research uses secondary data derived from annual reports, sustainability reports, financial reports, and stock price data. Data analysis method used in this research is Multiple Linear Regression using SPSS 26 Software. The first finding in this study showed that carbon emission disclosure had a significant and positive effect on firm value, this implies that the more detailed information on carbon emissions that is disclosed, the higher the firm's value, and vice versa. The second findings of this study showed that environmental performance has no significant effect on firm value, this indicates that environmental performance has no impact on the value of a firm, this demonstrates that investors continue to disregard environmental performance as measured by the ISO 14001 environmental standard when making investment decisions. The last findings of this study showed that environmental cost had an insignificant effect on firm value because investors still do not consider environmental costs when making investment decisions and because many industrial sector firms have not disclosed environmental costs in their social responsibility reports, so investors continue to miss the signals given by firms. This research contributes to the development of the sustainability accounting field.
Reduced-order models with delay

The paper considers the problem of H 2 optimal approximation of a high-order system by a low-order system with delay. An algorithm to solve this problem is presented. It consists of optimization with respect to the delay only where the rational part of the model and the quadratic cost are given by a solution of an equivalent order reduction problem without delay. It is shown by means of an example that introduction of delay into the model leads, in certain cases, to considerable improvement in the approximation. The results are extended to multiple-input multiple-output systems and also to frequency-weighted order reduction.
Appropriate Number of Center Points for Response Surface Exploration Using Small Box Behnken Design

Industrial exploration using the Box Behnken Design (BBD) has been faced with a serious setback due to the swift upsurge in the runs size as the number of factors increase. This, therefore, dissuades researchers and affects the application of the design. The Small Box Behnken Designs (SBBD) which achieve the research goal of BBD were proposed to overcome the setback. This paper aimed at recommending an appropriate number of center points suitable for response surface exploration and its applications in industries using the SBBD. The method adopted for assessing the center points is the prediction variance-based G-efficiency optimality criterion. The range of design factors, k, considered is 3 to 11, while comparing the designs at 0 - 5 number of center points. For each of the design factors considered, the result showed that increasing the center point, decreases the G-efficiency value. Hence, increasing the center point does not contribute significantly to the prediction variance capability of the designs considered. However, in other to test the model lack of fit and estimate pure error which are very important in experimental design analysis, this study recommends that at most two runs (center points) be replicated at the center. Since with this number, approximately 90% G-efficiency can be achieved for response surface exploration using the SBBD.
Impaired ribosome-associated quality control of C9orf72 arginine-rich dipeptide-repeat proteins

Abstract Protein quality control pathways have evolved to ensure the fidelity of protein synthesis and efficiently clear potentially toxic protein species. Defects in ribosome-associated quality control and its associated factors have been implicated in the accumulation of aberrant proteins and neurodegeneration. C9orf72 repeat-associated non-AUG translation has been suggested to involve inefficient translation elongation, lead to ribosomal pausing and activation of ribosome-associated quality control pathways. However, the role of the ribosome-associated quality control complex in the processing of proteins generated through this non-canonical translation is not well understood. Here we use reporter constructs containing the C9orf72-associated hexanucleotide repeat, ribosome-associated quality control complex deficient cell models and stain for ribosome-associated quality control markers in C9orf72-expansion carrier human tissue to understand its role in dipeptide-repeat protein pathology. Our studies show that canonical ribosome-associated quality control substrates products are efficiently cleared by the ribosome-associated quality control complex in mammalian cells. Furthermore, using stalling reporter constructs, we show that repeats associated with the C9orf72-expansion induce ribosomal stalling when arginine (R)-rich dipeptide-repeat proteins are synthesized in a length-dependent manner. However, despite triggering this pathway, these arginine-rich dipeptide-repeat proteins are not efficiently processed by the core components of the ribosome-associated quality control complex (listerin, nuclear-export mediator factor and valosin containing protein) partly due to lack of lysine residues, which precludes ubiquitination. Deficient processing by this complex may be implicated in C9orf72-expansion associated disease as dipeptide-repeat protein inclusions were observed to be predominantly devoid of ubiquitin and co-localize with nuclear-export mediator factor in mutation carriers’ frontal cortex and cerebellum tissue. These findings suggest that impaired processing of these arginine-rich dipeptide-repeat proteins derived from repeat-associated non-AUG translation by the ribosome-associated quality control complex may contribute to protein homeostasis dysregulation observed in C9orf72-expansion amyotrophic lateral sclerosis and frontotemporal degeneration neuropathogenesis.
On bandwidth choice in nonparametric regression with both short- and long-range dependent errors

We analyse methods based on the block bootstrap and leave-out cross-validation, for choosing the bandwidth in nonparametric regression when errors have an almost arbitrarily long range of dependence. A novel analytical device for modelling the dependence structure of errors is introduced. This allows a concise theoretical description of the way in which the range of dependence affects optimal bandwidth choice. It is shown that, provided block length or leave-out number, respectively, are chosen appropriately, both techniques produce first-order optimal bandwidths. Nevertheless, the block bootstrap has far better empirical properties, particularly under long-range dependence.
Assessing the Degree of Satisfaction, Duration, and Level of Cooperativeness among Patients Undergoing Flexible Bronchoscopy

Background: Bronchoscopy is an invasive procedure that has been used for a long time for diagnostic and therapeutic purposes. Objective: To assess the degree of satisfaction, duration, and level of cooperativeness among patients undergoing flexible fiberoptic bronchoscopy. Methods: The A quasi-experimental study was carried out on 128 flexible bronchoscopy patients that were equally divided into control and study groups. The program was applied only to the study group, and all procedure steps were discussed with patients by video records. The anxiety level score, patient satisfaction, and duration of the procedure were assessed in both groups. Results: The highest age range of patients was 61-90 years, with 38 patients from the study group (59.4%) and 44 from the control group (68.8%). Also, in both groups, most patients were illiterate, non-smokers, from nonduty areas, not city center residents, and had more than one associated comorbidity. The hospital anxiety scale was highly significant in the study group (p=0.0001), and the patient's satisfaction rate in the same group was significant (p=0.001). The procedure duration was significantly shorter in the study group (1.381 minutes) than in the control group. Conclusions: Patients with a better knowledge of the bronchoscopy procedure were more comfortable with the process, and the procedure duration was significantly shorter. Moreover, the process results in minimizing the levels of anxiety and improving the tolerability of the patients.
What drives the star formation in early-type galaxies at late epochs? - the case for minor mergers

Abstract Multi-wavelength photometry of early-type galaxies (ETGs) in the COSMOS survey is used to demonstrate that the low-level star formation activity in the ETG population at late epochs (z < 1) is likely to be driven by repeated minor mergers. While relaxed ETGs are almost entirely contained within the UV red sequence, their morphologically disturbed counterparts are largely found in the blue cloud, regardless of luminosity. Since empirically determined major-merger rates in the redshift range z < 1 are a few factors too low to account for the number fraction of disturbed ETGs, this suggests that minor mergers are the principal mechanism that drives star formation activity in ETGs at low and intermediate redshift.
