Abstract
In the current study, two algorithms, custom XG Boost (CXGBA) and improved genetic XG-Boost algorithm (IGXGBA) have been chosen to create an empirical formula for the simultaneous prediction of the mean fragmentation size (MFS) and the peak particle velocity (PPV) with sourced data sets of geo-blast parameters such as spacing burden ratio (S/B), stemming length (T), decking length (DL), firing pattern (FP), total quantity of explosive (TE), maximum charge per delay (MCD), measuring distance (MD), joint angle (JA), joint spanning height(JSP), joint set number (Jn), and rock compressive strength. Advanced technical combinations like K-10 cross-validation, and grid search executed along genetic algorithm processes with a high mutation rate to XGBoost algorithm. All algorithms were executed using Python programming in the Google Colab platform. The results unveiled that IGXGBA is superior and effective in-terms of metric R 2 , RMSE and MAPE in predicting MFS & PPV. A WEB APP called Bhanwar Blasting Formula (BBF) was created utilizing Google Cloud Platform (GCP) and FLASK APP to benefit practicing mining engineers to predict blasting results easily from the site itself, and identify optimization.

Abstract
Hot pepper is the dominant vegetable crop grown in different parts of Ethiopia with long history of cultivation and considerable genetic diversity for most important morphological traits. The study was undertaken to genetic variability and association among yield and yield related traits in the hot pepper. Analysis of variance revealed that there were a significant (P < 0.05) differences in genetic variation among genotypes for all morphological and fruit characters. The genotypic coefficient of variation ranged from 16.4–63.3% and phenotypic coefficients of variation ranged from 17.3–86.8%. All traits except fruit diameter showed highest genotypic coefficient of variation and phenotypic coefficients of variation. This indicates the presence of slight environmental influence to some degree in the phenotypic expression of the characters and it implies that the existence of substantial variability for such characters and selection may be effective based on these characters. The broad sense heritability values ranged from 53.3–99.4% whereas genetic advance as percent of mean was estimated in the ranged from 31.7–93.0%. Accordingly, both broad sense heritability and genetic advance were high for plant height, fruit number per plant, fruit diameter, fruit length, fruit diameter, and marketable yield. Hot pepper yield had positive and significant genotypic and phenotypic correlations with fruit weight, fruit length, fruit number per plants, unmarketable and marketable yield. Plant height, fruit diameter, fruit weight, fruit length, marketable yield, and unmarketable yield had positive direct effect in hot pepper yields at both genotypic and phenotypic levels.

Abstract
Lung nodules are high-risk factors for lung cancer, which often present as lung nodules in the early stages of lung cancer and have no obvious clinical symptoms. Identifying the benign or malignant nature of lung nodules can not only avoid over-diagnosis and over-treatment of benign pulmonary nodules but also save medical resources and reduce patients' psychological anxiety. Early detection, diagnosis, and treatment of lung cancer are crucial for reducing the mortality rate of lung cancer patients. In this study, we attempted to analyze the correlation of the tongue image features of benign lung nodules and lung cancer, using a bivariate correlation analysis that used Spearman correlation for variables that did not have a normal distribution and Pearson correlation for those that did, and a canonical correlation analysis for multivariate correlation between the two sets, mining the differences of the two groups' tongue image features in order to serve as a reference for classification models based on machine learning techniques. The results showed that there was a different association of diagnostic features on tongue images between patients with benign lung nodules and lung cancer. In the lung cancer group, the features of the tongue body and tongue coating had a stronger canonical association. In the group of benign lung nodules, the correlation coefficients for the first and second pairs of canonical variables were 0.918 and 0.817 (P < 0.01), respectively, whereas in the group of lung cancer, the correlation coefficients for the first and second pairs of canonical variables were 0.940 and 0.822 (P < 0.01). The objective data of tongue image provide a new methodological reference for the risk warning of lung cancer, it can be helpful in the risk warning of lung cancer to some extent.
A machine learning framework for the identification of crops and weeds based on shape curvature and texture properties
Authors: Agarwal Diwakar 
Published: June 2023

Abstract
Identification of weeds in a crop is a challenging problem for designing an automotive weed management system. Due to similar and indistinguishable properties between crop and weed, rather than single, various type of information is required for the successful discrimination of weeds against crops. This paper presents a machine learning-enabled weed classification system based on the fusion of handcrafted shape and texture features of a plant at the feature level. The shape features include several shape factors, region-based (Hu moment invariants), and contour-based descriptors (Fourier descriptors and shape curvature). Texture features include GLCM and LBP. A series of experiments are conducted to investigate the utility of shape curvature in the classification of weeds against crops. Furthermore, the potential of shape features including shape curvature and texture features has been examined by modeling the four classifiers, namely, SVM, KNN, MLP, and Naïve Bayes by using the 10-fold cross-validation approach. The classifiers are compared based on performance metrics- accuracy, error rate, recall, specificity, precision, and F1-score. Experimental results show that the SVM classifier achieved 93.67% overall accuracy with shape curvature features in the classification between crop and weed. In addition, the SVM classifier achieved 99.33% overall accuracy with the integration of shape with shape curvature and texture features.
Plant Systematics and Evolution Dwarfism of Ficus microcarpa L.f. in the Ryukyu Islands, Okinawa, Japan

Abstract
Ficus microcarpa, belonging to Moraceae, is an evergreen tree that can grow on tropical or subtropical rocky coasts. Recently, dwarf F. microcarpa individuals have been found on Nakanokamishima Island, Okinawa, Japan, but it remains unclear whether this dwarf trait is based on environmental plasticity or represents an intermediate stage of ecological speciation. To clarify the morphological and genetic traits of dwarfism and consider the process of ecological divergence, we conducted a common garden experiment and performed population genetic and structure analyses using 11 microsatellite markers. Moreover, we conducted a coalescent analysis to estimate the demographic parameters of two genetic clusters: dwarf and tree groups. Common garden experiments clearly classified the samples into two groups: dwarf and tree. In the STRUCTURE analysis, the highest ΔK value was obtained when K = 2, suggesting the existence of two genetic clusters: A and B. All samples collected on Nakanokamishima Island were classified into cluster B. Most samples from the other islands were classified into cluster A. Additionally, it was found that dwarf and tree lineages had diverged from an ancestral population hundreds or thousands of years ago. These results indicate that the dwarfism of F. microcarpa can be considered an ecotype defined as the intermediate stage of ecological speciation, and that dwarf individuals diversified very recently from an ancestral population with the existence of gene flow.

Abstract
Objectives Surgical mangement of comminuted patella fractures remains a major challenge for the surgeon. We developed a suture reduction (SR) technique to better preserve the comminuted patella. The study aimed to compare the suture reduction technique with conventional reduction (CR) technique in the management of comminuted patellar fractures using the modified Kirschner-wire (K-wire) tension band.
Methods From May 2016 to September 2020, a total of 75 patients with comminuted patellar fracture were reviewed retrospectively. Among these cases, 35 patients were in the suture reduction group with a mean age of 52 years, while 40 patients were in the conventional reduction group with a mean age of 53 years. All cases were closed fractures. Comminuted patellar fractures were classified as type 34-C3 according to the AO/OTA classification. Radiographs of the knee were obtained at routine follow-up to evaluate the reduction quality and fracture union. Clinical outcomes including range of motion (ROM), visual analog scale (VAS), Lysholm, and Böstman grading scales were measured at the last follow-up. Postoperative complications were also recorded.
Results The average time from injury to surgery was 5.4 days in suture reduction group and 3.7 days in conventional reduction group (p< 0.05). The surgical time of suture reduction group was less than that of conventional reduction group, but there was no significant difference (p= 0.110) regarding surgical time between the two groups. The average blood loss in suture reduction group was 42.9 ml, while the average blood loss in conventional reduction group was 69.3 ml (p< 0.001). There was no difference regarding fracture union, ROM and knee function score (Lysholm score and Böstman scale) between the two groups. The complication rates were 17.1% in suture reduction group and 12.5% in conventional reduction group respectively (p> 0.05).
Conclusions In the treatment of comminuted patellar fractures with modified K-wire tension band, the use of suture reduction technique can shorten the surgical time, reduce the surgical trauma, and obtain satisfactory results. This new surgical technique may be particularly effective in management of comminuted patellar fractures when patellectomy would otherwise be considered.

Published: June 2023

Abstract
Is it possible to identify a person where face recognition fails? This question has motivated us to search for the available procedures with which the task of human identification can be achieved. In this survey, various approaches that support the fact of identifying the person when the Face identification fails with the information on hand of person’s body structure and shapes. Here an attempt is made to consolidate and relates seemingly different terminology and methods which talks about the process involving how one does recognize a person when face identification fails? In general, when face identification fails, humans still tend to recognize the person based on the structure body posture and some time even from the back relying on the body but are unaware of doing so. Our objective is to develop a basic, straightforward system of person recognition based on person’s body type and gait movement. This primary recognition technique offers a lower constraint for assessing more complex procedures.

Published: June 2023

Abstract
LCD BCH codes are an important class of cyclic codes which have efficient encoding and decoding algorithms, but their parameters are difficult to determine. The objective of this paper is to study the LCD BCH codes of length n = (qm +1) / λ , where λ | (q + 1) is an integer. Several types of LCD BCH codes with good parameters are presented, and many optimal linear codes are settled. Moreover, we present the first few largest coset leaders modulo n = qm + 1 , (qm +1) / 2 , (3 m + 1) / 4, and partially solve two conjectures about BCH codes.

Published: June 2023

Abstract
Solid and liquid fractions of hydrothermally pretreated sugarcane bagasse (SCB) were simultaneously used as substrate of a novel continuous compartmentalized reactor. The effect of four (56, 42, 28, and 14 hours) hydraulic retention time (HRT) and chemical oxygen demand (COD) (0.5, 3.0, and 9.0 g/L) were evaluated on hydrogen (H2) and organic acids production. Higher H2 production and yield (686 mL and 1.63 mol/mol consumed carbohydrates, respectively) were obtained at HRT of 28 h, probably due to the Clostridium and Thermoanaerobacterium metabolisms, which accounted for almost 60% of the microbial relative abundance. Under lower and higher HRT (14 and 56 h, respectively) lactic acid predominated without hydrogen production. Other value-added chemical such as citric, valeric and caproic acids were also obtained as a function of HRT. From the functional point of view, enzymes from the glycoside hydrolases group (GHs) potentially performed important role in the lignocellulosic biomass bioconversion.
Property Rights and Cross-Country Heterogeneity in Consumption Volatility
Authors: Germaschewski Yin , Horvath Jay , Rubini Loris 
Published: June 2023

Abstract
Empirically, the relative volatility of consumption to output decreases with income. The standard small-open economy real business cycle model, however, produces a positive relationship. We can recover the negative relationship when we augment the standard model with micro-founded expropriations and estimate it using Bayesian methods for almost 60 countries. Introducing expropriations can also account for the observed cross-country heterogeneity in consumption-related moments better than the standard model, including the persistence and co-movement of consumption with output and investment. This is because an increase in expropriations reduces investment, freeing up resources for consumption, while moderately lowering output. These effects are more pronounced in poorer countries, where expropriations tend to be larger.

Pressure-induced phase transitions in Ni-bearing ferrosilite (Ni-En31Fs65)

Published: June 2023

Abstract
Orthopyroxene is an abundant mineral in subducting slabs. Studying its phase transitions at high pressure is important to the understanding of mineralogy of subducting slabs in the deep Earth. Synchrotron-based single-crystal X-ray diffraction experiments were conducted on a synthetic Ni-bearing ferrosilite (Ni-En31Fs65) at pressures up to 33.8 GPa. Three phase transitions were observed at 12.1(6), 15.6(6), and 31.3(25) GPa. The first two phase transitions in Ni-En31Fs65 resemble the previously described phase transitions in Ni-free Fe-rich orthopyroxenes, i.e., the initial α-opx (Pbca) transforms to β-opx (P21/c), then the latter transforms to γ-opx (Pbca). This indicates that the incorporation of a few mol% NiSiO3 does not influence the phase transition path of Fe-rich orthopyroxene. After the third phase transition, the structure (P21ca) of Ni-En31Fs65 resembles the previously reported β-popx observed in En90 at high pressure, although the onset pressure of the phase transition in Ni-En31Fs65 is ~7 GPa lower than that in En90. β-popx has a post-pyroxene structure that contains fivefold- and sixfold-coordinated Si cations. Our results indicate that the post-pyroxene structure is β-popx (P21ca) for either Fe-poor or Fe-rich orthopyroxenes, although the phase transition path before the pyroxene → post-pyroxene is compositionally dependent. Additionally, unlike the second and third transitions, whose onset pressures are monotonously decreased by increasing Fe content, the Fe effect on shifting the first transition is much more significant for orthopyroxenes within En &lt;50 mol% than that within En &gt;50 mol%.
Who Cares?

Published: June 2023

The changing tide of faculty has brought with it increasing numbers of faculty members serving in non-tenure-track roles. Scholars have argued this increase in contingent faculty includes an increase in inequities and has created a stratified class system between tenure-track faculty (TTF) and non-tenure-track faculty (NTTF). The majority of NTTF numbers comprise women of Color, across race and ethnicity, serving in both full-time and adjunct capacities. The cultural, historical, and sociopolitical occupation of women of Color in higher education has been rife with inequity, marginalization, and oppression. In addition to their duties across rank and appointment, women of Color faculty are more likely to take up the labor of care. Labor concerns have been raised in the both the literature of contingent faculty and women of Color faculty. Yet, few scholars have systematically studied the experiences or overlapping systems of oppression women of Color who are NTTF faculty face in the academy. Fewer still have examined the specific experiences of Black women faculty serving in contingent roles. For our study, we used a conceptual framework comprising Black feminist thought, care work, and labor justice to analyze scholarly personal narratives and focus group interviews of four Black women serving in full-time NTTF roles. Our study aims to provide a window into the intersected realities Black women contingent faculty members within the academy and a pathway forward for academic leadership.
Employing YPAR to Reflect on the Past, Present, and Future Promotes Black Girls to Learn about STEM Fields and Research.
Authors: Davis Shadonna 
Published: June 2023

The existent research seeking to explain why Black girls are less likely to participate in specialized pathways towards STEM fields suggests individual and systemic factors are the cause (Buck et al., 2009; Catsambis; 1994; Hanson, 2004; O'Brien, 2015; Perna, 2009). This study of six Black girls' participation in a 12-week Youth Participatory Action Research Project (YPAR) sought to extend this inquiry by prompting Black girls to examine the underlying causes for the low number of Black girls who participate in STEM courses at their school. The study also aimed to examine their knowledge of the growing concern related to the inequitable educational pathways to STEM fields. Qualitative data, including focus groups, field notes, documents, and observations, revealed that the girls knew that technology dominated society, but they were deeply concerned about young people being exposed to danger when using technology. We discovered their views were perpetuated by learned experiences in their households and by the media they consumed. The participants also recognized how their school environment influenced their perception of and ability to navigate their educational pathways. After participating in weekly workshops, the girls developed an interest in STEM activities and wrote an action plan to increase girls' engagement in school and STEM activities. The study findings also reveal how YPAR can promote girls to conduct a critical analysis of educational experiences, transform their perception of STEM education, and engage them in research.
Ain’t I A Woman: Black Women’s Endurance in Higher Education, the Implications of Linked Fate, and the Urgent Call for Greater Cultural Responsiveness
Authors: Butler Bettie R. 
Published: June 2023

National data on Black women in higher education has typically been presented through a deficit lens. General interpretations have suggested that in ‘comparison’ to white women, the rate at which Black women enroll in college or secure faculty appointments is less than ideal. While this data is intended to highlight systemic inequities in opportunities for Black women in higher education, too often it is (mis)used to justify the intellectual inferiority of the group. However, the same data—when examined through a critical lens—reveals something much more complex; which the present article attempts to unpack. Given the abounding obstacles Black women in academia experience due to the confluence of racism and sexism (and other interlocking systems of oppression), their perseverance, though painful at times, is rather remarkable and reason to pause and reflect; here’s why. Black women’s persistence is emblematic of our collective resistance to anti-Black structures, ideologies, and practices that are historically and deeply ingrained in institutions of higher education—namely, though not exclusively, predominately white institutions (PWIs). Beyond data points, Black women represent a collection of untold stories of struggle, advancement, and linked fate. When shared, stories provide strength, hope, and healing, and the courage to transform old systems and reimagine new academic spaces that recognize the humanity and value of Black women and their contributions to the academy. Given the importance of (counter)storytelling, the research highlighted within this current issue provides varied narrative and autoethnographic accounts of the lived experiences of Black women in higher education. Across each article are points for reflection and clear recommendations for action. More implicit, but nonetheless present, is an urgent call for greater cultural responsiveness in higher education. A topic that is introduced and explored briefly here in this opening article.
