Autonomous State Estimation and Observability Analysis for the Taiji Formation Using High-Precision Optical Sensors

In certain observation periods of navigation missions for the Taiji formation, ground observation stations are unable to observe the spacecraft, while the state of the spacecraft can be estimated through the utilization of dynamic equations simulated on prior knowledge. However, this method cannot accurately track the spacecraft. In this paper, we focus on appropriately selecting the available onboard measurement to estimate the state of the spacecraft of the Taiji formation. We design two schemes to explore the performance of the state estimation based on the interspacecraft interferometry measurements and the measurements obtained from the Sun sensor and the radial velocity sensor. The observability of the system is numerically analyzed using the singular value decomposition method. Furthermore, we analyze error covariance propagation using the cubature Kalman filter. The results show that using high-precision interspacecraft angle measurement can improve significantly the observability of the system. The absolute position and velocity of the spacecraft can be estimated respectively with an accuracy of about 3.1 km and 0.14 m/s in the first scheme, where the prior information of the precision of the position and velocity is respectively 100 km and 1 m/s. When the measurement from the radial velocity sensor is used in the second scheme, the estimation accuracy of the velocity can be improved about 18 times better than that in the first scheme.
Does the propagation technique affect phytochemical composition of raspberry and blackberry fruits?

In Serbia, the dominant methods of vegetative propagation of raspberries and blackberries are by root suckering (raspberry) and tip layering (blackberry), and they represent standard propagation techniques. However, due to the possible contamination of such planting material with viruses and phytopathogenic fungi, obtaining plants from tissue culture in vitro is becoming increasingly important. Therefore, the aim of this study was to investigate the fruit quality according to their chemical composition, emphasising the content of bioactive compounds in fruits of raspberry ( Rubus idaeus L.) ‘Meeker’ and blackberry ( Rubus fruticosus L.) ‘Čačanska Bestrna’ from plants propagated in the field by standard technique (ST) and grown in vitro micropropagation tissue culture (TC). A three-year experiment included the determination of the main fruit quality parameters (soluble solids, sugars, and total acids) by standard methods. The identification and quantification of phenolic compounds (protocatechuic, 4-hydroxybenzoic, ellagic, gallic, p-coumaric, caffeic and ferulic acids, quercetin, cyanidin, and pelargonidin) were performed using high-performance liquid chromatography (HPLC). The obtained results showed that the origin of the planting material did not significantly affect the quality of the fruits in terms of primary and secondary metabolites, except for 4-hydroxybenzoic acid in blackberries. This means that both (ST and TC) propagation methods allow obtaining fruits of equally good quality. Therefore, when choosing the type of planting material, other factors such as health, yield, and cost of planting material should be taken into account.

CHALLENGES FACING YEMEN REFUGEE WOMEN IN ADDIS ABABA, ETHIOPIA

Forced migration is associated with several challenges. The challenges that refugee women faced in their host countries were numerous. There has been a gender bias in Ethiopian literature on refugees. Refugees are homogenized in the existing studies. The gender differences among refugees have an impact on the challenges of forced migration that they encounter and how they handle them. Moreover, no study has been done on the adaptation challenges faced by Yemeni refugee women in Addis Ababa. This study's main objective was to examine the challenges that Yemeni refugee women faced in Addis Ababa. An interpretative phenomenological analysis was employed to achieve that objective. Thirteen Yemeni refugee women were interviewed using a semi-structured interview guide to understand their experiences. Purposive sampling was used to choose study participants. The data was analyzed using interpretive phenomenological analysis procedures. The study's findings revealed that refugee women encountered several challenges that were detrimental to their well-being, including language difficulties, limited income and job opportunities, unrecognized identity papers and price increases, and housing problems. Furthermore, refugee women faced social isolation and sexual harassment. The study concluded that the challenges that Yemeni refugee women faced in Addis Ababa had an enormous impact on their well-being, which demands immediate intervention.
Fast Decoding of Sequence Rate-1 or SPC Nodes for Polar Codes

Due to the sequential nature of the successive-cancellation (SC) algorithm, the decoding of polar codes suffers from significant decoding latencies. Fast SC decoding is able to speed up the SC decoding process, by implementing parallel decoders at the intermediate levels of the SC decoding tree for some special nodes with specific information and frozen bit patterns. To further improve the parallelism of SC decoding, this paper present a new class of special nodes composed of a sequence of rate one or single-parity-check (SR1/SPC) nodes, which can be typically found in high-rate polar codes and is able to envelop a wide variety of existing special node types. Then, we analyse the parity constraints caused by the frozen bits in each descendant node, such that the decoding performance of the SR1/SPC node can be preserved once the parity constraints are satisfied. Finally, a generalized fast decoding algorithm is proposed to decode SR1/SPC nodes efficiently, where the corresponding parity constraints are taken into consideration. Simulation results show that the proposed decoding algorithm of the SR1/SPC node can nearly achieve maximum-likelihood (ML) performance, and the overall SC decoding latency can be reduced by 43.8% as compared to the state-of-the-art fast SC decoder.
Uptake of nitric acid in ice crystals in persistent contrails

This is a short version of Schauble et al. (2009) published in ACPD. In November 2006 cirrus clouds and almost 40 persistent contrails were probed with in situ instruments over Germany and Northern Europe during the CIRRUS-III campaign. At altitudes between 10 and 11.5 km and temperatures of 211 to 220 K contrails with ages up to 8 hours were detected. These contrails had a larger ice phase fraction of total nitric acid (HNO3,ice/HNO3,tot = 6 %) than the ambi- ent cirrus layers (3 %). The differences in ice phase fractions between developing contrails and cir- rus are likely caused by high plume concentrations of HNO3 prior to contrail formation and large ice crystal number densities in contrails. The observed decrease of nitric acid to water molar ratios in ice with increasing mean ice particle diameter suggests that ice-bound HNO3 concentrations are controlled by uptake of exhaust HNO3 in the freezing plume aerosol in young contrails and subse- quent trapping of ambient HNO3 in growing ice particles in older (age > 1 h) contrails.
Short Communication The Caiçaras and the Atlantic Forest coast: Insights on their resilience

In this study we approach temporal resilience, at an ecological scale, by comparing 22 years of activities of Caicaras in Puruba Beach, SE coast of Brazil. Caicaras are the local inhabitants of the Atlantic Forest coast, descending from Portuguese Colonizers, Native Indians, as well as with African influences. Resilience is a subject of great relevance when dealing with inhabitants of tropical forests, especially when considering livelihoods that depend upon the extraction of natural resources. Puruba beach was studied in 1991 (AB) and 2013 (GP) (who conducted semi-structured interviews), among other studies. The inhabitants of Puruba beach showed flexibility and capacity to manage the restrictions imposed by the governmental environmental agencies. They engaged in new jobs at the municipality of Ubatuba, and diversified their activities. In that regard, they were capable to adapt to new realities by diversifying and substituting their economic activities, showing socio-economical and ecological resilience.
The Impact Of Perceived Social Support On The Academician's Flourishing While Mediated By The Organizational Identification

This study aimed to evaluate the direct and indirect impacts of perceived social support on the flourishing of academic professionals. Based on pertinent research, it has been shown that academicians' perspectives on organizational identification serve as mediating factors in investigating the indirect connections between these two constructs. A structural equation model has been developed and validated using suitable statistical techniques, with organizational identification as the foundation. Four study hypotheses were formulated based on the theoretical frameworks of social exchange and social identification theory. These hypotheses encompass the direct influence of perceived social support on academicians' flourishing and the indirect effect of organizational identification acting as a mediator. The present study examined the mediating function of organizational identification in the relationship between perceived social support and academician flourishing after identifying the interactions among variables. Relevant statistical approaches such as partial least squares structural equation modeling (PLS-SEM) were employed to analyze the data. The study employed many statistical techniques, including data analysis, reliability testing, item-total correlation analysis, regression analysis, and the t-test. The study's findings indicate sufficient supervisor and organizational support at higher educational institutions in Sindh, Pakistan, which considerably impacts academicians' flourishing. However, it was observed that co-worker support does not play a significant role in contributing to their flourishing. The results of this study indicate that organizational identification serves as a partial mediator in the association between supervisor support and organizational support. Nevertheless, organizational identification did not demonstrate any mediating influence in the correlation between co-worker support and the flourishing of instructors. The present study utilizes a theoretical and structural model to examine the perceived social support (supervisor, co-worker, and organization), employee flourishing, and organizational identification among faculty members at Public sector higher educational institutions in Sindh, Pakistan. Therefore, it is recommended that targeted measures be used to provide authentic relational support inside Pakistani higher education institutions by implementing coaching initiatives, establishing discussion forums, providing orientations, and implementing learning programs. These measures aim to promote academicians' well-being and professional development in higher education institutions.
Numerical simulation and experimental diagnostics of fast electron kinetics and plasma parameters in a microhollow cathode discharges in helium

The paper presents the results of studies of plasma parameters and kinetics of fast electrons in the region of negative glow of a discharge with a microhollow cathode at high pressures based on a hybrid model that includes a kinetic description of electrons and a fluid description of the heavy plasma component. The results of numerical calculations are compared with the results of probe studies. It is shown that the hybrid model makes it possible to accurately describe the formation of electron energy distribution function peaks from fast electrons produced as a result of Penning ionization reactions and superelastic collisions. The results of numerical calculations make it possible to predict the parameters of the negative glow plasma in discharges with a microhollow cathode in pure helium and in helium with impurities of various gases, including organic ones.
Effects of the Types of Headphones and Sound Sources on Spatial Audio Quality

Acoustic characteristics of sound fields reproduced by headphones are a major concern to evaluate spatial audio quality. Several specifications exist for acoustic attributes, including frequency response, impedance, and sensitivity. While prior research has illuminated these acoustic features, it falls short in evaluating the spatial audio quality produced by headphones. Such studies don't sufficiently detail the impact of headphones and sound sources. In this study, we carried out psychological evaluations and acoustical measurements of sound fields reproduced by headphones to identify the acoustic elements that account for the spatial audio quality rendered by the headphones. Three types of sound excerpts were played with seven types of headphones, and the psychological evaluations were carried out by 30 participants. Envelopment and apparent source width were evaluated as psychological evaluations. From the binaural impulse response, we determined the center time (Ts), the maximum value (IACC) of the interaural cross-correlation function (IACF), and the IACC width (WIACC). We derived the IACF and auto-correlation function (ACF) parameters from the recorded sound sources. The traits of both the headphones and the sound source influenced the psychological assessments. The variation in spatial audio quality across headphones and sound sources can be attributed to the peak value of the initial maximum amplitude of the ACF, Ts, and WIACC.
The Effect of Asset Structure, Size, Growth and Profitability of The Company on The Capital Structure of Manufacturing Companies

The purpose of this study is to analyze empirical factors that affect capital structure in manufacturing companies in Indonesia. In this study the independent variables are asset structure, company size, growth and profitability. The dependent variable is the capital structure defined as the ratio of debt to assets. The population in this study is manufacturing companies listed on the Indonesia Stock Exchange during 2007-2016. There were 181 manufacturing companies, using purposive sampling method, 119 manufacturing companies used as a sample of selected population companies that had never been delisted from the Indonesia Stock Exchange during 2007-2016. The sample type is panel data, which is a combination of cross section data with time series data. This research uses quantitative methods and data analysis using panel data regression with a fixed effect model approach. The result is that asset structure, company size and profitability have a significant negative influence on the debt-to-asset ratio, but the growth shows no significant influence of about 69.27% between all independent variables with dependent variables and 30.73% contributed by other parties. Independent variables exclude asset structure, company size, growth and profitability.
Constructivist Referents in Oumar Farouk Sesay’s ‘The Song of the Women of My Land’

The purpose of the research was to examine the constructivist referents in Oumar Farouk Sesay’s poem ‘The Song of the Women of My Land’. This required an analysis and understanding of the referents (terms that clearly and indirectly refer to persons, things or events) and whether the referents were used in the poem to express grief by women. The research questions were as follows: a) Does the poet use referents that suggest the death of traditions that celebrate old women, song bards, and songs from the past more than any other word? b) Is the poet more likely to employ poetic allusions to indicate negative constructivism? and c) Is the poem’s use of prosodic features related to the message? This study used computational and content analysis methods, which incorporate a careful poetry-reading critical approach, to identify and calculate constructivist referents. The referents were then manually broad-coded to include whole lines and verses. The exact words, phrases, and sentences related to the topic were coded and their frequency was determined. These were calculated by counting the number of times a referent appeared. The themes were then selected and interpreted, with a focus on relating them to the poem’s constructivist viewpoint. Finally, the main prosodic elements of the poem, as well as the referents that create them, were established. The results show that most referents by African poets are used to emphasise that traditional culture is dying and that the referents romanticise the fleeting nature of beauty in poetry and the pacifying effects of rural pastimes.
Cryptocurrency investment behaviour of young Indians: mediating role of fear of missing out

Purpose This study aims to investigate how fear of missing out (FOMO) mediates the relationship between cryptocurrency adoption intention and investment behavior among young Indians, using the extended unified theory of acceptance and use of technology. Design/methodology/approach The data were collected by using survey items on cryptocurrency adoption intention, investment behavior and FOMO derived from existing literature on information systems and cryptocurrencies. A total of 384 Indian participants completed an online questionnaire. The collected data was analyzed using PLS-SEM. Findings The findings indicate that facilitating conditions, social influence, effort expectancy and price value play important roles in cryptocurrency adoption. All hypothesized paths were significant, except for perceived risk. Furthermore, the study highlights that FOMO acts as a mediator between adoption intention and investment behavior. Originality/value This study makes a valuable addition to the literature by empirically exploring the influence of FOMO on the adoption of cryptocurrencies for investment purposes. The results provide valuable insights to crypto developers and exchanges regarding the diffusion of adoption in emerging markets. In addition, policymakers can gain meaningful insights into the influence of government regulations and FOMO on impulsive cryptocurrency behavior.
QUATERNARY GEOLOGY AND TILL GEOCHEMISTRY OF THE BONAVISTA PENINSULA

Surficial geology mapping and a regional till geochemistry survey were completed on the Bonavista Peninsula and areas to the west. Mapping involved the identification of landform and sediment types and included the measurement of paleo iceflow indicators, as a means of reconstructing the areas' ice-flow history. Sampling of surface tills was at a density of 1 sample per 1 km 2 in areas of road access, to 1 sample per 4 km 2 in areas where helicopter support was required. A total of 1135 samples were collected during the survey. During the last glaciation, the Bonavista Peninsula was almost entirely covered by eastward-flowing ice, derived from an ice dispersal centre to the west of the study area, likely Middle Ridge. Glacier flow was drawn down into Goose Arm, Sweet Bay and Southern Bay and thence into Bonavista Bay, or through Smith Sound, Northwest Arm or Trinity Harbour into Trinity Bay. This drawdown effect was more pronounced as the ice began to thin and became topographically controlled during deglaciation. The Bonavista Peninsula, north of a line between Trinity and Plate Cove West, was covered by an independent ice centre. Ice flow from this latter centre was coastward from a northeast–southwest-trending ice divide that followed the height of land. Deglaciation was toward the major dispersal centres. The trend of esker ridges on the Tug Pond area shows westward retreat, likely toward the Middle Ridge area. Raised marine terraces are found at similar elevations around the peninsula (maximum 28 m asl), suggesting simultaneous retreat of ice and the accompanying marine incursion. The timing of deglaciation and the pattern of postglacial sea-level change are uncertain because of the paucity of dateable material.
Chemistry and mineralogy of some Lower and Middle Chalks from Givendale, East Yorkshire

Abstract The chemical composition of nine samples of Lower and Middle Chalk from the Givendale area of Yorkshire was determined; acetic acid residues were mechanically, chemically and mineralogically analysed. All nine chalk samples proved to be exceptionally pure calcium carbonate (96±1·5%), with only small amounts of MgO (1·03±0·53%), Al2O2 (0·33±0·28%) and Fe2O2 (0·20±0·14%). Insoluble residues ranged from 1·07 to 4·46%. Clay formed 56–88% of the insoluble residue. The non-clay fraction consisted of flint, quartz, collophane, limonite, feldspar, tourmaline and zircon. The clay fractions were dominated by montmorillonite (50%) with secondary illite (30%), apatite (3%), and quartz (8–30%). Kaolinite was detected by X-ray diffraction in the Lower Chalk.
MISSION STATEMENTS AND VISION STATEMENTS: EXAMINING THE RELATIONSHIP TOWARD PERFORMANCE OUTCOMES

This paper examines 798 firms with mission statements and vision statements to show there are relationships between the two and posits that strong relationships produced greater organizational performance. Using the taxonomies of Allison (2017a), Allison (2017b), and an extension of the latter developed in this paper, the statements are classified into their taxonomic groups and then analyzed statistically. The results surprisingly show a single strong link between one type of mission statement and one type of vision statement. This paper then discusses how such a relationship may result in superior performance outcomes. Consequently, this paper significantly contributes to theory by finding a specific relationship between statements, discussing why some firms have this relationship, and then extending this discussion to organizational performance. are relationships between types of mission statements and types of statements and these findings to conclusions about performance.
