Inverse Length Biased Maxwell Distribution: Statistical Inference with an Application

In this paper, we suggested and studied the inverse length biased Maxell distribution (ILBMD) as a new continuous distribution of one parameter. The ILBMD is obtained by considering the inverse transformation technique of the Maxwell length biased distribution. Statistical characteristics of the ILBMD such as the moments, moment generating function, mode, quantile function, the coefficient of variation, coefficient of skewness, Moors and Bowley measures of kurtosis and skewness , stochastic ordering, stress-strength reliability, and mean deviations are obtained. In addition, the Bonferroni and Lorenz curves, Gini index, the reliability function, the hazard rate function, the reverse hazard rate function, the odds function, and the distributions of order statistics for the ILBMD, are presented. The ILBMD parameter is estimated using the maximum likelihood method, the method of moments, the maximum product of spacing technique, the ordinary and weight least square procedures, and the CramerVon-Mises methods. The Fishers information, as well as the Rényi and q-entropies, are derived. To investigate the usefulness of the proposed lifetime distribution and to illustrate the purpose of the study, a real dataset of the relief times of 20 patients receiving an analgesic is used.
Combating and perpetuating bias: the relationship between bias and computer science

This paper aims to explore the relationship between computer science and bias, analysing case studies and discussing the social implications of ways that software can both combat and perpetuate bias. While some areas of computer science such as software design and its underlying algorithms may be developed to offer an objective, data-driven decision, free from human bias, bias can nonetheless appear almost anywhere in the software development process. This has the potential to affect the design, algorithms, and testing of software, thus impacting its ultimate usability. There will be a focus on the Western bias that exists in the design of human-computer interactions, as well as the potential to and corresponding effects of introducing bias into artificial intelligence and machine learning algorithms. This work will simultaneously discuss the significance and corresponding implications within society of the many forms of bias in some computer science areas.
Evaluating the Impact of an Autonomous Playing Mode in a Learning Game to Train Oral Skills of Users With Down Syndrome

The use of ICT tools is broadly extended among people with intellectual disabilities and also, to a lesser degree, the use of learning tools including learning games. Although the use of learning games is widely accepted due to its high engagement capacity, there are few studies that analyze its usability for people with intellectual disabilities. This work presents an evaluation of the impact of adding an autonomous playing mode on the usability of a learning game designed to aid the training of oral skills in people with Down syndrome. A study in which the effectiveness, efficiency and user satisfaction of a learning game are compared when the system is used with different degrees of teacher supervision is carried out. A learning game originally designed to train oral competencies for people with Down syndrome in a teacher supervised scenario is adapted to allow its autonomous use, by including a module that provides the automatic assessment of oral productions. The use of the tool is thus compared in three different scenarios: a supervised environment, autonomous use, and laboratory use with multiple users working in parallel. The different usability evaluation instruments used reveal that, although there are no differences in the degree of engagement, there may be important differences regarding session performance: the quality of the audios is lower in the laboratory sessions and the number of errors increases in the autonomous sessions. We conclude that, although the autonomous use of learning games by users with intellectual disabilities is possible, and this can lead to considerable savings in human resources, if the feedback provided by the game is not comparable with that provided by the teacher, performance may drop considerably although the degree of engagement is maintained.

Segmentation Technology of Nucleus Image Based on U-Net Network

To solve the problems of rough edge and poor segmentation accuracy of traditional neural networks in small nucleus image segmentation, a nucleus image segmentation technology based on U-Net network is proposed. First, the U-Net network is used to segment the nucleus image, which stitches the feature images in the channel dimension to achieve feature fusion, and the skip structure is used to combine the lowand high-level features. en, the subregional average pooling is proposed to improve the global average pooling in the attentionmodule, and an attention channel expansionmodule is designed to improve the accuracy of image segmentation. Finally, the improved attention module is integrated into the U-Net network to achieve accurate segmentation of the nuclear image. Based on the Python platform, the experimental results show that the proposed segmentation technology can achieve fast convergence, and the mean intersection over union (MIoU) is 85.02%, which is better than other comparison technologies and has a good application prospect.
KOH-activated carbon developed from biomass waste: adsorption equilibrium, kinetic and thermodynamic studies for Methylene blue uptake

AbstractIn this paper, fallen coconut (Cocos nucifera) leaves were used as precursors to prepare activated carbon by thermal carbonization using KOH-activation method. The physical properties of the prepared coconut leaves-activated carbon (KAC) were calculated through the bulk density, ash content, moisture content, and iodine number. The surface characterization of KAC was undertaken using Scanning Electron Microscopy, Fourier Transform Infrared, and point of zero charge (pHPZC) method. Batch mode experiments were performed to assess the influence of the adsorbent dose (0.02–0.25 g), initial pH (3–11), initial dye concentration (30–400 mg/L), contact time (5–300 min), and temperature (303–323 K) on the adsorption of the methylene blue (MB). The kinetic uptake profiles are well described by the pseudo-second-order model, while the Langmuir model describes the adsorption behavior at equilibrium. The adsorption capacity (qm) of KAC increased with temperature where qm varied as follows; 147.1 (303 K), 151.5.
Modification of Polyaniline-Based Gas Sensor by Electrophoretic Deposition of Metal Nanoparticles in Ionic Liquids

Nanoparticles synthesized in various ionic liquids (ILs) were immobilized by electrophoretic deposition (EPD) at the surface of a gas sensor made of thin polyaniline (PAni) film. We used pulsed DC voltage to overcome electrochemical treatment in IL-based electrolytes. In spite that EPD is commonly used for synthesis of nanoparticle films or coatings, here we just functionalized the surface of PAni by scattered nanoparticles. Immobilized nanoparticles were observed by SEM imaging and dynamic responses of gas sensors functionalized by different nanoparticles (Ni, Ni-Fe and Ag-Cu) were compared. Using the EPD technique, sensitivity or selectivity of a gas sensor based on PAni can be improved easily.
An analysis of arches of the foot: Grading the severity of pesplanus and pescavus using a newly designed podoscope and parameters

Introduction: The aim of this study was to establish a new grading system of pesplanus (PP) and pescavus (PC) based on the severity by a newly proposed parameter plantar surface area (PSA) using a newly designed podoscope device. Material and Methods: A total number of 416 healthy participants; 208 men and 208 women aged 21–50 years were included in this study. Plantar surface images were obtained from the podoscope and measurements were made by using the newly proposed parameter and existing parameter. Statistical analysis was conducted using the SPSS Statistical software (version 16.0) and executed at 95% confidence interval. Mean and standard deviations were observed by using the descriptive analysis. The Chi-square test has been performed to find the association, dependency, and validity. Results: The analysis of the present study encompasses the grading system of “PP and PC” and also developed a classification system with three grades in PP and PC. This grading system will be a substantiate assessment tool for the diagnosis and also to record the prognosis during the treatment of PP and PC. Discussion and Conclusion: The present study has developed a newly designed podoscope and established a newly proposed parameters PSA index and analyzed the prevalence of normal, PP and PC. In this study, gender wise normative value for new parameters PSA index was proposed under the influence of height and foot length. According to our knowledge, this is the first study to grade the PP and PC in a proper scientific morphometric analysis using a newly designed podoscope with a PSA index.
Retinal Vascular Abnormalities in Different Types of Inherited Retinal Dystrophies Assessed by Optical Coherence Tomography Angiography

Purpose: To investigate the retinal vascular characteristics among patients with different types of inherited retinal dystrophies (IRDs). Methods: This comparative cross-sectional study was conducted on 59 genetically confirmed cases of IRD including 37 patients with retinitis pigmentosa (RP) (74 eyes), 13 patients with Stargardt disease (STGD) (26 eyes), and 9 patients with cone-rod dystrophy (CRD) (18 eyes). Both eyes of 50 age- and sex-matched healthy individuals were investigated as controls. All participants underwent optical coherence tomography angiography to investigate the vascular densities (VDs) of superficial and deep capillary plexus (SCP and DCP) as well as foveal avascular zone area. Results: In RP, significantly lower VD in whole image (P = 0.001 for DCP), fovea (P = 0.038 for SCP), parafovea (P < 0.001 for SCP and DCP), and perifovea (P < 0.001 for SCP and DCP) was observed compared to controls. In STGD, VD of parafovea (P = 0.012 for SCP and P = 0.001 for DCP) and fovea (P = 0.016 for DCP) was significantly lower than controls. In CRD, the VD of parafovea (P = 0.025 for DCP) was significantly lower than controls. Whole image density was significantly lower in RP compared to STGD (P < 0.001 for SCP) and CRD (P = 0.037 for SCP). VD in parafovea (P = 0.005 for SCP) and perifovea (P < 0.001 for SCP and DCP) regions was significantly lower in RP compared with STGD. Also, foveal VD in STGD was significantly lower than RP (P = 0.023 for DCP). Conclusion: Our study demonstrated lower VDs in three different IRDs including RP, STGD, and CRD compared to healthy controls. Changes were more dominant in RP patients.
Principles and practices of biosafety: Expanding and extending to food safety and food supply chain

The perception of biosafety on food and supply chains moves around the philosophical axis of “coping and living with occupational health hazards” to upheld the sustainable development of occupational safety. COVID-19 pandemic opened the “Pandora's box” of prevailing lackadaisical attitude on the basic public health aspects principles that should apply to food safety and food supply chain. We must revamp the collaboration of food production and public health-care delivery system to save the community by containing the spread of highly infectious agent from known and unknown natural and artificial reservoirs. Equity of distribution of quality and quantity of the food and nutrition has to be ensured for the majority of the global population at this crossroads of socio-economic crisis which has pauperized en masse as the negative fallout of pandemic. Food safety should be an urgent agenda for comprehensive internalization and be supplemented with the mitigation plan to minimize psychosomatic stresses and revitalize emotional and psychosocial health by targeted interventions. There is dire need of translational research and holistic streamlining of biosafety program in the phase of the rising trend of the cases and sequels epidemiologic pandemic curve on ground. Needless to mention that apart from SARS-COV2, the holistic concept of the implementation of the biosafety programs can interrupt the transmission of innumerable infectious agents from the plant and animal resources. Biosafety models were reviewed for high laboratory standards in the real time “new normal” situation of containment and risk assessment in this unprecedented pandemic of new millennium.
Risk Factors for Ocular Surface Disease in Tunisian Users of Preserved Antiglaucomatous Eye Drops

Purpose: To study the clinical and the functional findings in glaucomatous patients under preserved eye drops having ocular surface alterations and to analyze their risk factors. Methods: A cross-sectional study of 155 glaucomatous patients was conducted. All of them answered the “Ocular Surface Disease Index” (OSDI) questionnaire and had a complete and precise evaluation of the ocular surface state including a Schirmer I test, a tear break-up time evaluation, eyelid, conjunctival, and corneal examination with a Fluorescein and a Lissamin green test. We studied factors that could influence the OSDI score and each type of ocular surface alteration (age, sex, glaucoma treatment duration, number and type of the active principle, and Benzalkonium Chloride [BAK] use). Results: BAK was used in 80% of cases. The OSDI score was ≥13, in 61.3% of cases. The biomicroscopic signs of ocular surface disease were at least minimal in 87.1% of cases. The main predictors of OSDI score increase were the glaucoma treatment duration (P = 0.01, t = 2.618), the number of molecules used (P = 0.018, t = 2.391), and the use of BAK (P = 0.011, t = 2.58). The severity of the biomicroscopic signs correlated with these same risk factors. Fixed combination was statistically associated with a lower incidence of superficial punctate keratitis (SPK) and corneal and conjunctival staining in the Lissamine green test (P < 0.001). Beta-blockers were associated with a significantly higher risk of SPK and corneal or conjunctival staining in the Lissamine green test (P < 0.001). Conclusions: Preserved antiglaucomatous eye drops alter the patients' ocular surface. The main risk factors were advanced age, duration of glaucoma treatment, multiple therapies, and the use of BAK.

This study aims to assess the association between infertility in women and fibromyalgia. Material and Methods: To participate in this study, 476 patients referred to our hospital were selected. The study group consisted of 230 infertile participants, and the control group consisted of 246 fertile participants. The participants were examined and 43 of them were diagnosed with FS according to the 2010 ACR criteria. General information about the participants was received, and their BMI was measured. Participants responded to the Common pain scale (YGAS), Symptom Severity Scale (SSS), and Fibromyalgia Impact Questionnaire (FIQ). Results: The age of the participants ranged from 20 to 45, with a mean of 29.5 (±5.05) years. The participant’s BMI range was 20 to 29.8, with a mean of 24.7 (±2.4). The common pain scale in the study and control groups was 4.24 (±2.3) and 3.3 (±1.7), respectively. The difference in this variable between the two groups was significant (P-value= 0.000). The symptom severity scale in the study and control groups was 2.4 (±1.3) and 1.6 (±1.06), respectively. The difference in this variable between the two groups was significant (P-value= 0.000). The Fibromyalgia Impact Questionnaire score for fertile participants ranged from 30 to 70, with an average of 53 (±14.8). There was no significant difference between the groups. Discussion: Our results showed that infertile women have more fibromyalgia symptoms than fertile women. This result may indicate an association between fibromyalgia and infertility.
Floral traits and flowering behaviors of Malaysian rice cytoplasmic male sterile and maintainer lines and its relationship with out-crossing performance

Rice is a strictly self-pollinating crop. However, in hybrid rice seed production, an effective male sterility system is used to produce hybrid seed in bulk. In hybrid rice system, the pollen grains of cytoplasmic male sterile (CMS) are sterile and the female organ of the CMS depends on the fertile pollen released by the maintainer or restorer lines via out-crossing or cross-pollination in order to produce seed. Floral trait and flowering behavior of CMS and its corresponding maintainer or restorer lines are essential factors in hybrid rice seed production because they influenced the out-crossing or cross-pollination between parental lines. Two local CMSs and their corresponding maintainer lines were developed through breeding program in Malaysian Agricultural Research and Development Institute (MARDI) namely 0025A/0025B and 0047A/0047B. This study was carried out on floral traits and flowering behavior of these two hybrid line. Present studies have shown that there were variations between the CMS and its maintainer lines whether on floral trait or flowering behavior for both hybrid rice combinations. The results showed that stigma characters for both 0025A and 0047 were superior than their respective maintainers. Therefore, it is expected that the out-crossing rate would be high. Seeding date intervals need to be done on 0025A/0025B during nursery stage because the on-set of flowering between parental lines was significantly different. Panicle of both CMS was also classified as just exserted and partially-exserted and application of exogenous hormones such as gibberellic acid was useful to improve panicle elongation and consequently increase the seed set and yield. Correlation study indicates that the stigma area of both 0025A and 0047A has significant positive correlation with out-crossing rate.
Implementing Smarteye-Fishy URL Detection Using URL Features and CNN

Phishing attacks are very common but are the least defended security menaces today. An approach is proposed which makes use of Natural Language Processing techniques to detect statements which are indication of phishing attacks. NLP offers a natural solution for this problem as it is capable of analyzing the textual content to perform intelligent recognition and performing semantic analysis of text to detect malicious intent. In this type of cyber-attack, the attacker sends malicious links or attachments through phishing e-mails that can perform various functions, including capturing the login credentials or account information of the victim. The standard way to specify page layouts is through the style sheet (CSS), the developed algorithm detects similarities in key elements related to CSS. Phishing detection includes approach that uses profiles of trusted websites’ appearances to detect phishing.
Fixed Points in Compositions and Words

We study fixed points in compositions (ordered partitions) of integers and words. A fixed point is a point with value i in position i. Using generating functions and probabilistic arguments, we enumerate the compositions and words with no fixed points and p fixed points and also how many fixed points occur on average. We briefly discuss the average maximum (respectively minimum) fixed point and the sum of sizes of fixed points. Moreover we provide asymptotic results for the above parameters.
Early marriage and spousal age difference: predictors of preconception health of young married women in Delhi, India

Purpose – This study aims to assess the associations of early marriage and spousal age difference (independent of early marriage) with reproductive and sexual health and autonomy in decision-making among married women before conception. Design/methodology/approach – The present study was a part of a three-year community intervention to improve the preconception health of young married women (20–35 years) in the West Delhi district of India. The six key outcomes assessed were: knowledge of reproductive health, discussions related to sexual health, history of anemia, use of contraceptives by women, frequency of consumption of meals per day and the autonomy in decision-making for household expenditures. Unadjusted and adjusted logistic regressionmodels were used to explore the associations between the two key predictors (earlymarriage or spousal age difference), sociodemographic variables and six outcomes. The results were expressed as odds ratio (OR) and 95% confidence interval (CI). A total of 2,324 women, enrolled from four wards in the district using cluster-based sampling, were interviewed. Findings – Around 17% of women were married by the exact age of 18, and 20% were elder or just one year younger than their husbands. Women who were married early had low reproductive health knowledge (OR (95% CI): 0.48 (0.38–0.60)) and a lower probability of expressing autonomy (OR (95% CI): 0.78 (0.62–0.97)). However, women older than men or younger by just one year in the married relationship had higher reproductive health knowledge (OR (95% CI): 1.25 (1.01–1.54)) than women younger than men more than two years. Originality/value – Under the umbrella of the preconception care domain, frontline workers should emphasize counseling girls and young women to marry late and delay the first pregnancy.
