The potential of indocyanine green fluorescence detection in surgical cut margin of breast conserving surgery.

Fluorescence-guided surgery (FGS) is a cutting-edge technology that uses near-infrared (NIR) fluorescence imaging to guide surgeons in surgery. Indocyanine green (ICG) is a fluorescent dye, which can be used for in vivo imaging of tumor cells. We aimed to explore the use of ICG fluorescence-guided technology as a rapid intraoperative margin assessment method for breast cancer surgery. In addition, we also compared the dose selection of ICG. This was a non-randomized prospective cohort study. Data were collected between August 2021 and October 2022 in the Division of Breast Surgery, Department of General Surgery, Nanjing Drum Tower Hospital, the Affiliated Hospital of Medical School, Nanjing University. Upon specimen removal, tumor margins were immediately analyzed by ICG fluorescence detection and then sent to the pathology department for intraoperative frozen section analysis and subsequent routine pathological examination. Abnormal margin rates were calculated and compared using intraoperative frozen section analysis and under the guidance of ICG fluorescence. The study included 69 cases of breast cancer patients who underwent tumor resection assisted by ICG fluorescence-guided technology, including 18 patients with a 0.5 mg/kg dose and 51 patients with a 1.0 mg/kg dose. According to the study findings, the ICG test achieved a sensitivity of 81.82% and a specificity of 75.82%. At a dose of 0.5 mg/kg, the sensitivity was 66.67% whereas the specificity was 93.33%. At the dose of 1 mg/kg, the sensitivity was 87.5%, and the specificity was 74.42%. Similarly, for intraoperative frozen section analysis, the sensitivity was 81.82%, but the specificity was enhanced to 94.83%. Positive surgical cut margin was not identified in 2/69 by ICG fluorescence and frozen section analysis respectively. The sensitivity of ICG fluorescence detection is comparable to that of frozen section analysis, but the specificity is poor. The sensitivity increased and the specificity decreased at 1 mg/kg compared to the 0.5 mg/kg dose. ICG fluorescence can be used as a supplementary tool for frozen section analysis. These findings support further development and clinical performance assessment of ICG fluorescence.

Защита деталей горного оборудования, работающих в условиях подземных выработок от биокоррозии

Introduction. Biological corrosion of mining equipment parts is an important problem. Ti-Cu-based coatings provide effective protection against such corrosion. A significant number of mining equipment parts operate under conditions of intense wear. These are parts such as pins, rollers, gears, racks, drive stars, etc. When applying a coating to such parts, it is important not only to increase the anti-corrosion properties, but also to maintain or improve the tribological properties of the parts being processed. The use of coatings based on metal oxides is an effective tool to combat bio corrosion. Among such metal oxides, nanocomposites that include a combination of TiO2 and Cu2O have performed best. These composites have a narrow bandgap, chemical stability and low toxicity. However, the issue of their influence on the tribological properties of parts remains incompletely studied. The purpose of this work is to analyze the structural features, mechanical properties and wear resistance of the Ti-TiO2-Cu-Cu2O coating applied by detonation spraying. Materials and methods. In this work, Ti-TiO2-Cu-Cu2O composite coatings were formed on a steel substrate. Sputtering was carried out using a multi-chamber detonation accelerator system. The coating process was carried out layer by layer using a device that moved back and forth with a lateral displacement. Titanium (PTN-8VT10) and copper (PMS-1) powders were used as raw materials. Wear tests were carried out using a disk-pin design. X-ray structural analysis was carried out for the obtained samples, and the microstructure of the coatings was studied. The micro hardness of the applied coating was also determined. Results. In the resulting coatings between the two elements Ti and Cu of the deposited powders, no chemical reaction or intermetallic compounds were detected. Ti-TiO2-Cu-Cu2O composite coatings mainly consisted of TiO2 and Cu2O, with titanium and copper acting as a binder, providing a high density of the composite material. Distinct formations of metallic Ti and Cu particles are observed in various regions of the microstructure, with many formations of metallic Ti retaining their spherical shape. The Ti-TiO2-Cu-Cu2O coating has a high average hardness of 640 HV0.2. The coefficient of friction when the Al2O3 counter body slides over the coating after a short running-in cycle did not change and amounted to 0.38. Discussion. The analysis of the cross section revealed that the coating material has a dense structure, characterized by strong inter lamellar-type connections, and has no signs of destruction or cracks. The absence of cracks and delamination along the boundary between the substrate and the coating indicates the high quality of adhesion to the base. The thickness of this composite coating is approximately 340 ± 20 micrometers. The increased hardness of this coating can be explained by the partial melting and rapid solidification of powder particles during spraying, as well as its lamella-type compositional structure. The micro hardness profile inside the Ti-TiO2-Cu-Cu2O coating remains uniform. During tribo-technical tests with a 100Cr6 counter body, the friction coefficient of the tribo couple after running-in decreased as the sliding cycles increased. This effect is due to the formation of a tribo layer on the worn surface of the coating, which serves as protection against severe wear. These conditions prevent the counter body from sticking to the coating surface, which reduces the likelihood of adhesive wear. The main composition of the sealing tribo layer is iron oxide, formed as a result of an increase in temperature on the sliding surface and wear of the steel counter body during dry sliding, which prevents adhesion in contact. Conclusions. The authors conclude that during the spraying of a Ti-Cu powder mixture, ceramic reinforcement is formed, where titanium and copper, interacting with atmospheric components at the time of spraying, are capable of forming new oxide phases. Due to the absorption of oxygen by titanium and copper during the deposition process, the resulting composite acquires an average micro hardness of 640 HV0.2. The analysis of the cross-section of the coating revealed that the coating has a thickness of about 300 microns, has a dense structure characterized by strong interlamellar-type connections, and has no signs of destruction or cracks. Resume. The results obtained show that Ti-TiO2-Cu-Cu2O coatings applied to critical parts of mining equipment not only protect them from bio-corrosion, but also increase tribological properties. This allows you to increase the maintenance-free service life of equipment in mining operations. Suggestions for practical applications and future research directions. Ti-Cu composite coatings obtained by detonation thermal spraying can be used for such parts of mining equipment as pins, rollers, gears, racks, drive stars, etc. These coatings can be used not only to protect mechanisms and structural elements in mining conditions, but also for equipment elements operating in humid climates.

A Case Study on Economic Analysis of Sea Cage Farms in the Black Sea, Türkiye

The main aim of this research is to understand the value chains of enterprises engaged in aquaculture in sea cages in the Black Sea region of Türkiye, to determine production costs and to make a general analysis of the aquaculture sector. Random sampling method was used to ensure that farmers were equally represented in the survey. Data for the survey were randomly selected from 16 separate farms spread throughout 4 different marine cage locations. Furthermore, fish traders and sector stakeholders were interviewed. The businesses examined within the scope of the study are divided into 3 groups: small (250 -500 tons/year), medium (501-999 tons/year) and large (>1000 tons/year), according to their capacities. The most important expense items of enterprises consist of variable costs. Among the variable costs, the purchase of fry fish, feed purchase, and labor costs constitute the most important expenditure items. Among the fixed costs, the most important expense is depreciation costs. The unit cost of one kg of fish varies between 2.7 and 3.0 euros. Considering that the trout (Oncorhynchus mykiss) and seabass (Dicentrarchus labrax) in the Black Sea are at the level of 3.5 Euro, the profit rate of the enterprises is between these levels. Recently, since trout from the Black Sea has been exported to the Far East Country (particularly Japan), its price has also increased. In 2018, the average retail price (including VAT) and medium selling price of seabass and trout were at a level of 5.24 and 5.34 Euros respectively. Despite all these positive developments, climate change continues to pose a threat in terms of disease outbreak and marketing problems.

Corruption In Morocco-A Sectorial Analysis

Corruption, a pervasive socio-economic problem, has a significant impact on Morocco, reflecting a global challenge that undermines trust in public institutions and hinders development. This phenomenon, often defined as the abuse of public power for private gain, results in widespread citizen distrust of their government and public institutions. Recognizing the critical need to address this issue, Morocco has implemented various strategies and reforms at the institutional and civil society levels to combat corruption. Our study aims to provide a sectoral analysis of corruption in Morocco, assessing the prevalence of corrupt practices and the effectiveness of anti-corruption measures put in place. Using a descriptive methodology, our research relies on secondary data from various databases, including Transparency International's Corruption Perceptions Index (CPI) from 2004 to 2023. This index provides a longitudinal perspective on how perceptions of corruption have evolved in Morocco over the years and serves as a key indicator of the effectiveness of anti-corruption efforts. Our findings indicate that despite these efforts, corruption remains entrenched in several sectors, suggesting that the strategies adopted have not yet succeeded in significantly changing the corruption landscape. This analysis underscores the complexity of fighting corruption in Morocco and highlights the need for continued efforts and innovative strategies to effectively address this endemic problem.

Experimental and numerical investigation on flexural behavior of steel-UHPC composite slabs with PBL shear connectors

A full-scale flexural test was conducted to investigate the flexural and cracking behavior of Steel-UHPC Composite Slabs (SUCS) with PBL (Perfobond rib) shear connectors, with a focus on analyzing the impact of the tensile reinforcement ratio on flexural performance. During the test, the flexural performance of SUCS was assessed through measurements of strain, mid-span deflection, relative slip, crack width, and crack morphology. A section analysis was performed to predict the flexural and cracking behaviors of SUCS, which was further verified by experimental results. The results show that the PBL shear key effectively ensures the overall force of steel plate and UHPC plate, resulting in good ductility of SUCS under negative bending moment. As tensile reinforcement ratio increased from 0.89 % to 1.69 %, the cracking load remained stable while the yield load and ultimate load demonstrated significant improvements of 54 % and 57 %, respectively. The cross-section analysis indicated that with the increment in tensile reinforcement ratio, the contribution of tensile reinforcement to flexural capacity increased, whereas the contribution of UHPC to tensile capacity notably decreased. The equivalent uniform stress reduction coefficient of the UHPC's tensile zone, determined through simplified negative flexural bearing capacity, was calculated to be 0.87. The failure mode of negative flexural resistance differs significantly from positive flexural resistance, as it involves the breaking of the tensile steel bar.

A Survey Based Analysis: Labor-Market with Young Workforce or Adequate Governmental Policies? Key attributes of Person-Job Fit in Kosovo

The synergy of Person-Job fit has long been an important construct within the labor market in developed, but more so in developing countries. Personality attributes comprise a psychology framework, which can predict and explain human behavior. Nevertheless Person-Job fit is moderated by contextual contingency. In this vein, the question of how personality attributes interact with job-related indicators such as job performance continue to acquire scholars’ attention. Consequently, this research aims to answer this question, by applying a survey-based analysis in Kosovo, to identify key personality attributes impacting Person-Job fit. Kosovo has a huge dividend of a young work-force, which has been found as an instrument mitigating the gap of Person-Job fit, considering the high rate of unemployment. The research approaches two methods in verifying the impact of personality attributes on job related competences, based on survey data, a) first it presents the empirical evidence analysis, and b) validates the statistical significance of personality characteristics to the job-related tasks, applying a General Linear Model-Multivariate Testing Simulation (GLM-MVA). Both methods confirm the significant correlations of attitudes and perceptions having an impact on the daily job performance, however with a mitigating role of the contextual indicators. The findings show that more than a half of the working force declare that they fit to their job, which in an analysis perspective has two reasons: 1) the unemployment rate, and 2) the young work-force rate. Both aspects shape the inner personal perceptions of having a job and the way they perform at the job. However, within sector analysis, there is a discrepancy between the private and public sector, making the latter more compatible for the working force. This is justified by the fact that in Kosovo the public sector makes people feel more secure about their job, therefore showing a higher rate of satisfaction. At the end, the research adds some key policy reflections, attributed to dimensions, such as: educational reform system, and the fragile governmental policies addressing employment in Kosovo, to help construct a stable framework of Person- Job fit.

Comprehensive crashworthiness simulation analysis of a large aircraft fuselage barrel section in various crash scenarios

To utilize computational techniques in investigate and evaluate the crashworthiness of typical fuselage section of a large transport aircraft in various crash scenarios, the finite element model of fuselage section was modeled and validated based on the vertical drop test of fuselage section at 6.02 m/s. The crash simulation analysis in various crash scenarios (such as concrete ground, soft soil grounds and water) were further conducted based on the validated model of fuselage section, and the crash response characteristics (deformation and failure mode, acceleration response and occupant injury risk, energy-absorbing characteristics) were analyzed and compared. The results show that the finite element model can accurately simulate the unrolling failure mode (three plastic hinges failure mode) of fuselage section and the failure of the connections of cargo floor crossbeams and fuselage frames, and it is in good agreement with the test results in terms of impact velocity and acceleration response. In the case of various soft soil grounds impact scenarios, the partial impact energy is absorbed by the soft soil ground, resulting in slightly different failure modes of fuselage section and a reduction in the peak acceleration. The water-entry impact failure mode of fuselage section is consistent with the rigid ground impact failure mode, the overall deformation degree of fuselage section decreases, but the degree of bending and upturning of fuselage frames increases with the increasing of the water-entry impact velocities The safety of occupants can be effectively protected in the soft soil ground and water-entry impact scenarios. The unrolling failure mode of fuselage section can be changed to the flattening failure mode (multiple plastic hinges failure mode) through the reasonable design to avoid the rupture of cargo floor crossbeams, and the more crash energy can be absorbed due to the production of more plastic hinges for the flattening failure mode, and the crashworthiness of fuselage section can be significantly improved.

Trend Analysis and Spatial Source Attribution of Surface Ozone in Chaozhou, China

Surface ozone (O3), a critical air pollutant, poses significant challenges in urban environments, as exemplified by the city of Chaozhou in southeastern China. This study employs a novel combination of trend analysis and spatial source attribution techniques to evaluate the long-term dynamics of surface ozone and identify its sources. Utilizing the Kolmogorov–Zurbenko (KZ) filter and percentile regression, we analyzed the temporal trends of daily maximum 8 h moving average ozone (MDA8 O3) concentrations from 2014 to 2023. Our analysis revealed a general long-term downward trend in MDA8 O3 values alongside notable monthly fluctuations, with peak concentrations typically occurring in October and April. Additionally, the percentile regression analysis demonstrated a significant downward trend in MDA8 O3 concentrations across nearly all percentiles, with larger decline rates at higher percentiles, highlighting the effectiveness of local and regional O3 management strategies in Chaozhou. The changes in MDA8 O3 concentrations were mainly influenced by the short-term component, contributing 62.2%, while the contribution of the long-term fraction is relatively small. This suggests a significant influence of immediate meteorological conditions and transient pollution events on local O3 levels. To further elucidate the origins of high O3 concentrations, trajectory cluster analysis, trajectory sector analysis (TSA), and potential source contribution function (PSCF) analysis were conducted. The trajectory cluster analysis revealed that the northeast air mass was the main transport air mass in Chaozhou during the study period, accounting for 39.1% of occurrences. The northeast cluster C with medium-distance trajectories corresponds to higher concentration of O3, which may be the main transport pathway of O3 pollution in Chaozhou. TSA corroborates these findings, with northeast sectors 1, 2, and 3 accounting for 50.3% of trajectory residence time and contributing 52.2% to O₃ levels in Chaozhou. PSCF results further indicate potential high O₃ sources from the northeast, especially in autumn. This comprehensive analysis suggests that Chaozhou’s elevated O3 levels are influenced by both regional transport from the northeast and local emissions. These findings offer crucial insights into the temporal dynamics of surface O3 in Chaozhou, paving the way for more effective and targeted air quality management strategies.

Evaluasi Kinerja Steam Jet Ejector Tingkat Pertama Terhadap Kevakuman Kondensor

The steam jet ejector is a device for extracting NCG from the condenser. NCG can increase the pressure in the condenser until a vacuum condition is not reached. The diffuser pressure on the steam jet ejector has a normal operational limit of below 1 atm, meaning that the ejector performance will be optimal if it is operated at the operational limit under vacuum conditions. The expected objectives are to determine the effect of the steam jet ejector on condenser vacuum, calculate the performance of the first level steam jet ejector through pressure analysis in the diffuser section, calculate the performance of the steam jet ejector in actual conditions compared to the design data conditions and analyze actions that can be taken to improve the performance of the tool. Based on the results of calculations and analysis, it was found that the increase in steam jet ejector pressure had an effect on the increase in condenser pressure from the design pressure of 0.10 bar to 0.107-0.123 bar under actual conditions. The decrease in steam jet ejector performance results in the condenser vacuum level decreasing, but the equipment performance is within normal operational limit conditions, namely below 1 atm. The decrease in steam jet ejector performance is influenced by the motive steam mass flow rate, NCG mass flow towards suction, entrainment ratio value, NCG pressure and motive steam pressure which exceeds the design data.

Combined Pubic Arch and Ischial Bone Resection for Metachronous and Frequent Local Recurrences of Rectal Cancer.

Complete surgical resection with negative margins remains the cornerstone for curative treatment of rectal cancer; however, local recurrence can pose a significant challenge. Herein, we aimed to introduce a novel surgical technique for combined resection of the pubic arch and ischial bone in the context of treating recurrent rectal cancer. We present a case of a patient with a fourth local recurrence of rectal cancer, with no evidence of distant metastasis. The tumor directly invaded the posterior wall of the pubic arch. To achieve complete tumor resection, an osteotomy was performed using a thread wire saw at the bilateral pubic rami and ischial bones. Intraoperative frozen section analysis (rapid tissue examination) was conducted on tissue samples from the lateral margins of the planned osteotomy line. Samples were negative for adenocarcinoma (cancerous cells). The combined resection of the pubic arch and ischial bone was successfully performed with negative margins for adenocarcinoma, as confirmed by frozen section analysis. Mastery of the surgical technique for combined resection of the pubic arch and ischial bone may be clinically significant for achieving complete resection in cases of multiple resections for locally recurrent rectal cancer.

Sustainability dimensions in the mission, vision and value statements of the largest corporations in Ghana: a sectoral analysis

PurposeThe purpose of this paper is to compare how the various sectors among the largest companies in Ghana have incorporated sustainability into their mission, vision and value statements.Design/methodology/approachThe mission, vision and value statements of the 100 largest corporations in Ghana, known as Ghana Club 100 (GC100), were extracted from the firms’ official websites. These firms were grouped into nine sectors, and the sustainability components in the mission, vision and value statements were subjected to cross tabulation and thematic contents analysis to establish the sectoral variations.FindingsIn formulating their mission, vision and value statements, GC100 firms were more than six times likely to include economic sustainability themes than environmental sustainability themes. Even though three out of every five GC100 firms are financial institutions, the manufacturing and the extractive sectors and firms ranked 1st−20th are three times likely to incorporate all the sustainability dimensions (i.e. economic, social and environmental) into their mission, vision and value statements. Firms in the financial sector and those ranked 80th−100th were more likely not to publish either a mission, vision or value statements online.Practical implicationsThis study reveals the magnitude of the strategic pronouncements such as mission, vision and value statements of large firms in emerging economies and how they are aligned with sustainability. This could serve as a basis for formulating guidelines to reinforce efforts that contribute to corporate sustainability.Originality/valueResearch on how large firms align sustainability into their mission, vision and value statements is not a new agenda, but fragmented in the context of the emerging economies. The novelty is that this study addresses this gap and contributes to this topic from a sectoral comparative perspective of largest organization in Ghana, an emerging economy.

Complete analysis of differential cross section in 7 Li + γ→→ 6 Li + n at astrophysical energies

We have carried out complete analysis of differential cross section in 7 Li + γ → 6 Li + n using model-independent theoretical formalism. A complete analysis of the reaction involves measurements of not only one state of linear polarization of the photon but also another state of linear polarization inclined to the first at 45◦ and two states of circular polarization of the photon. An analytical study of the differential cross section including all the photon polarization states is carried out at near-threshold energies of interest to Big Bang Nucleosynthesis.

New Understanding of the Early Cambrian Uplift–Depression Framework and the Large-Scale Source–Reservoir Distribution along the Margin of the Awati Sag in Tarim Basin, NW China

The uplift–depression framework controls the source–reservoir assemblage. However, the exploration breakthrough is restricted by an insufficient understanding of the uplift–depression differentiation framework in the Early Cambrian Keping–Wensu area. In this paper, based on field outcrops evaluations, thin section analysis, logging data, drilling data, and 3D seismic data, Wensu low paleo-uplift was discovered in the northern Tarim Basin, and the planar distribution was demonstrated in detail, generally shown as a SW–NE trending nose structure, extending roughly 114 km in length to the southwest, about 35 km in width to the northeast, and with the overall characteristic of being high in the west and low in the east. During the Early Cambrian, the Tabei paleo-uplift evolved into the Wensu low paleo-uplift and largely died out by the Middle Cambrian, with the development of ramps and rimmed carbonate platforms. The tectonic-sedimentary evolution of the uplift–depression framework controlled the development of a set of main source rocks and two sets of large-scale effective reservoir rocks in the Lower Cambrian, constituting two sets of effective hydrocarbon accumulation in the upper and lower stratigraphic parts of the basin. Among them, the upper assemblage holds more potential for hydrocarbon exploration, and is expected to be a next strategic target area for hydrocarbon exploration of Cambrian subsalt in the Keping–Wensu area.

Evaluation of Reservoir Properties of Sylhet Limestone of Jaintia Group, North-Eastern Sylhet, Bangladesh

The Sylhet Limestone in the Bengal Basin, formed in the Eocene Epoch and known for its fossil content, is significant in understanding the reservoir characteristics. Despite exposure in Jaflong and Takerghat of the Bengal Basin, little research has been conducted on reservoir characteristics. This study aimed to comprehensively examine the Sylhet Limestone Formation, encompassing its crystalline upper and fossiliferous lower sections. It utilized field investigations and laboratory analyses to address the gaps of sporadic or insufficient earlier studies. A thorough examination of thin sections from the Sylhet Limestone, exposed in the Dauki River area, provides insights into the textural and mineralogical attributes and the presence of skeletal fossils within the limestone. Based on the analysis of thin sections, the limestones are categorized as Rudestones and Packstones. The porosity observed in the exposed rocks ranges from 5% to 12%, with most pores associated with interconnected fractures and joints. However, thin-section studies also indicate evidence of diagenetic recrystallization and calcite cementation. Hence, closely spaced, interconnected joints and fractures filled with diagenetic calcite might deteriorate the reservoir quality. Notably, this limestone exhibits fossilized specimens such as Nummulite, Discocyclina, Alveolina, Assilina, and Ostracoda, among others. The combination of the fossil assemblage, limestone texture, and composition strongly suggests that this limestone formation was deposited in a shallow marine environment with minimal sediment input under a warm and humid climate. The petrographic analysis of the limestones concludes that the upper portion of the formation is fine-grained while the lower part is coarse-grained.

Hydration energies of calcium hydroxide cation, CaOH+(H2O)x (x = 1–6), studied using guided ion beam tandem mass spectrometry

Hydration energies of CaOH+(H2O)x, x = 1–6, were obtained using threshold collision-induced dissociation (TCID) with xenon (Xe) as conducted with a guided ion beam tandem mass spectrometer (GIBMS). The primary reaction pathway observed for all complexes is the loss of one water ligand, followed by the loss of additional water molecules at higher collision energies for x > 1. The kinetic-energy-dependent cross sections for dissociation of CaOH+(H2O)x complexes were modeled to obtain 0 K binding energies after accounting for lifetime effects, energy distributions, and pressure effects. Except for x = 5, experimental threshold energies measured through TCID agree well with theoretical hydration energies determined using B3LYP/6-311+G(d,p) structure geometries followed by single point energies calculated at B3LYP, B3P86, M06, and MP2(full) levels of theory with a 6-311+G(2d,2p) basis set. B3LYP-GD3BJ and ωB97XD calculations were also used, with the former yielding results having the best agreement with the threshold energies extracted from the analysis of the TCID cross sections.

Combined axial load-biaxial bending interaction method for L-shaped CFSP shear walls

This paper reports the development of axial load and biaxial bending interaction method for L-shaped concrete-filled steel plate (CFSP) composite shear walls based on fiber section analysis model using the uniaxial constitutive relationship of materials. Owing to the complex interaction between the two perpendicular wall limbs (web and flange) of an L-shaped shear wall, the contour shape of the My-Mz curve is asymmetric. Linear transformation was employed to reduce the asymmetry of the contour shape, eliminate the influence of dimension, and perform parametric analysis. The analysis results indicate that when 0° ≤ θ(neutral axis angle) ≤ 90°, the influence of width-to-thickness ratio (hw1/bw) and shape coefficient (γ) on the coefficient that controls the contour shape (α) was negligible. The effect of shape coefficient (γ), steel content ratio (ρ), compressive strength of unconfined concrete (fc0), and yield strength of steel plate (fyp) on α is not significant for −180° ≤ θ ≤ −90°. Further, simplified equations were suggested to determine α. The axial load-moment interaction curve expressions for distinctive loading directions were determined by establishing the calculation method for the curve's characteristic points (axial load capacity, bending capacity, boundary points). Subsequently, the characteristic points were combined with the contour shape of the axial load-moment interaction curve derived by fitting the finite element simulation data to generate the axial load-moment interaction curve equations. A design approach was finally formulated based on the equations for the biaxial moment capacity curve and the axial load-moment interaction curves of the characteristic loading directions.

Corporate financial distress prediction using the risk-related information content of annual reports

This study presents a financial distress prediction model focusing on the linguistic analysis of risk-related sections of corporate annual reports. Here, we introduce a novel methodology that leverages BERT-based contextualized embedding models for nuanced extraction of financial sentiment and topic coherence. This stands in contrast to existing research, which predominantly relies on dictionary-based or non-contextual word embeddings and addresses their limitations in context sensitivity. Furthermore, we apply an innovative financial distress prediction model that combines the robust XGBoost algorithm with unsupervised outlier detection techniques. This hybrid model is specifically designed to tackle the issue of class imbalance, a persistent challenge in financial distress prediction. The efficacy of the proposed model is empirically validated using a comprehensive dataset of 2545 companies listed on major global stock exchanges. Our findings indicate that the introduced model not only significantly outperforms most existing state-of-the-art financial distress prediction models in terms of predictive accuracy, but also significantly outperforms the Loughran & McDonald dictionary-based approach and the Word2Vec model, underlining its potential as a superior analytical tool for financial distress prediction.

Perceptions of supervisors and their doctoral students regarding the problems in writing the doctoral dissertation results section

In the past, whereas much attention has been paid to exploring doctoral dissertation writing as a whole or the move analysis of results section, there is a dearth of studies examining how the problems keep posing for doctoral EFL students in writing such a section. The current study focused on students' problems when they write the results section of their dissertations in the fields of education and chemistry, and investigated the degree to which students' understanding was in line with that of their supervisors through semi-structured interviews with ten pairs of supervisors and students. The results showed that (1) disciplinary differences played an important role in writing the results section; (2) supervisors and students in the same discipline understood the purposes of writing the results section to a certain extent, but the overall result varied in different disciplines; (3) there was a lack of agreement between supervisors and students regarding the reasons for the students' problems, especially in the field of chemistry; and (4) students, regardless of discipline, tended to attribute their problems to limited language proficiency while their supervisors provided reasons other than that. In light of the findings, the pedagogical implications for writing instruction are discussed.
