The Effective Capacitance of a Constant Phase Element with Resistors in Series
Authors: Chang Byoung-Yong
Published: September 2022

The power of energy storage devices is characterized by capacitance and the internal resistance. The capacitance is measured on an assumption that the charges are stored at the electrode interface and the electric double layer behaves like an ideal capacitor. However, in most cases, the electric double layer is not ideal so a constant phase element (CPE) is used instead of a capacitor to describe the practical observations. Nevertheless, another problem with the use of the CPE is that CPE does not give capacitance directly. Fortunately, a few methods were suggested to evaluate the effective capacitance in the literature. However, those methods may not be suitable for supercapacitors which are modeled as an equivalent circuit of a CPE and resistor connected in series because the time constant of the equivalent circuit is not clearly studied. In this report, in order to study the time constant of the CPE and find its equivalent capacitor, AC and DC methods are utilized in a complementary manner. As a result, the time constants in the AC and DC domains are compared with digital simulation and a proper equation is presented to calculate the effective capacitance of a supercapacitor, which is extended to an electrochemical system where faradaic and ohmic processes are accompanied by imperfect charge accumulation process.

Published: September 2022

The aim of this study is to determine whether or not the breed and sex factors have an effect on the shape in the mandibles of Hamdani and Awassi sheep. A total of 31 mandibles were used. The samples were analyzed via geometric morphometric methods by using semilandmark. In the study, it was determined that the first principal component accounted for 36.52% of the total shape difference. According to principal component analysis, samples were clustered significantly in terms of breed; whereas, they were not clustered in terms of sex. In terms of the first principal component, the places where the shape differences were concentrated were the attachment sites of teeth to the mandible, between the second molar and ramus mandibulae, the processus coronoideus and the angulus mandibulae. The Mandibulae of Hamdani sheep had a higher body than the mandible of Awassi sheep. The mandibulae of male sheep was more voluminous than the mandible of female sheep, especially in the body area. Consequently, it is thought that the data obtained as a result of the study would serve as a reference for the ruminant mandible remains obtained from archaeological excavations.

Authors: Theile Harrison , Walsh Sara , Scougall Peter , Ryan Damian , Chopra Shiv
Published: September 2022

**Objective**: Goniometer measurements are commonly used in hand clinics to follow progress or as an outcome measure for acute and chronic conditions. The use of a smartphone goniometer application may provide a practical alternative for clinicians. This study sought to assess accuracy in range-of-motion measurements obtained by a smartphone goniometer application compared to a traditional universal goniometer in healthy and diseased hands.**Methods**: Patients with various hand disease processes were recruited through a tertiary hospital hand clinic, as well as healthy volunteers. Middle and little fingers were assessed at the metacarpophalangeal (MCP), proximal interphalangeal (PIP) and distal interphalangeal (DIP) joints for flexion and extension. Measurements were taken using a universal goniometer and an iPhone® smartphone goniometer application by two independent evaluators using a standardised proforma.**Results**: Twenty patients were recruited (50% male; 13 healthy volunteers and seven with hand pathology). There were no significant differences in measurements using the smartphone goniometer. The only significant difference found using the universal goniometer was for little finger PIP joint flexion; however, the difference was only 2.5°. Comparison of the average measurements using universal and smartphone goniometers found significant differences for six joints, with none of these >5° (largest 4.6°).**Conclusion**: The goniometer iPhone® application is as reliable as traditional goniometry techniques and would be a practical tool for everyday use in hand clinics. Its uptake may provide broader utility for patient self-measurement and telemedicine.

Data analysis and predicting play an important role in managing heat-supplying systems. Applying the models of predicting the systems’ parameters is possible for qualitative management, accepting appropriate decisions relating control that will be aimed at increasing energy efficiency and decreasing the amount of the consumed power source, diagnosing and defining non-typical processes in the functioning of the systems. The article deals with comparing two methods of ma-chine learning: random forest (RF) and support vector machine (SVM) for predicting the temperature of the heat-carrying agent in the heating system based on the data of electronic weather-dependent controller. The authors use the following parameters to compare the models: accuracy, source cost and the opportunity to interpret the results and non-obvious interrelations. The time spent for defining the optimal hyperparameters and conducting the SVM model training is deter-mined to exceed significantly the data of the RF parameter despite the close meanings of the root mean square error (RMSE). The change from 15-min data to once-a-minute ones is done to improve the RF model accuracy. RMSE of the RF model on the test data equals 0.41°С. The article studies the importance of the contribution of variables to the prediction accuracy.

The widespread use of computer technology, its rapid development and use in almost all areas of human activity requires constant updating of information security issues. The activities of many enterprises in the field of IT, construction, and other areas are of a project nature and therefore further research on information security management of projects is relevant. Appearance of changes and the current state of the project results at certain points of time describe the documents that accompany it. In this paper, the information structure of the project is considered as a set of specific documents. During the life cycle of each project document, which includes the creation, transfer, preservation and transformation, there are generally threats to its confidentiality, integrity, accessibility and authenticity. This paper develops a method for assessing the risks of violation of the availability of project documents in solving information security problems. A formal description of many project documents in the form of a generalized hierarchical structure is presented, the connection of documents with the operations performed on them and information systems used during these operations is formalized. Given the incompleteness and dimension of the data, the based on fuzzy logic model was developed to assess the risk of document accessibility. Approaches to the assessment of the damage from the violation of the availability of the project document and the method of calculating the overall assessment of the risk of violation of the documents availability are proposed. The results presented in this paper can be used in decision-making processes regarding information security of projects in organizations that have project activities. The approaches proposed in this paper can serve as a basis for the creation of specialized information technologies to automate the calculation of project risk assessments.

Published: September 2022

Abstract: Dural Arteriovenous Fistulas (AVF) represent about 10% of all intracranial vascular lesions. Although they seem benign in nature, the presence of retrograde venous makes them aggressive, with a high risk of complications. Patients may be clinically asymptomatic or experience symptoms ranging from mild to severe hemorrhage, depending on their location. Different treatments are available, but recently, the development of catheter intervention allows most patients to be cured with transcatheter embolization. Stereotactic radiosurgery achieves excellent rates of obliteration for low-grade lesions. In this review, we try to highlight the recent advances in the management of dural AVF.

Published: September 2022

Correction of sexual function in animals is a topical issue today, despite a large amount of scientific data on this problem. The study aimed to scientifically substantiate the effectiveness of hormonal veterinary drugs in cats and dogs of different breeds and genders. Veterinary drugs with the active substance megestrol acetate were used in the experiments. The studies were performed on clinically healthy cats and dogs of both sexes, different breeds, and ages vaccinated against infectious diseases and treated with antiparasitic drugs. The study was conducted according to the current regulatory documentation. It has been found that the use of hormonal drugs to interrupt/delay estrus in female cats at a dose of 5 mg of megestrol acetate for 8 days leads to a significant decrease in follicle-stimulating hormone, and the content of luteinizing hormone in the blood of cats in the experimental groups reliably decreased throughout the experiment. The use of contraceptives based on megestrol acetate in doses of 2.5 mg for 14 days for cats leads to a reliable decrease in the concentration of testosterone in the serum. It was found that the use of experimental hormonal drugs for female dogs in doses of 5 mg of megestrol acetate per 2.5 kg of body weight in the first 3 days, and half the daily dose from the 4th to the 10th day, leads to a reliable decrease in concentrations of follicle-stimulating and luteinizing hormones in serum compared to the control. Oral administration of experimental hormonal drugs to male dogs in doses of 5 mg of megestrol acetate per 2.5 kg of body weight for 8 days, led to a reliable decrease in the concentration of testosterone in the serum of males. It was found that the estrous cycle in female cats and dogs of the experimental groups after the cessation of hormonal drugs was completely restored, which indicates the safety of drugs with an active ingredient megestrol acetate

Authors: Reindl Tomáš , Hruška Viktor , Frič Marek
Published: September 2022

This study presents the results of research on the psychological aspects of exactly calculated just intonation intervals, which was performed in the form of a listening test. These micro-interval nuances (śruti) are attributed specific emotions or feelings in ancient Indian music-theoretical texts, just as in the European tradition, various extra-musical qualities have been attributed to different intervals or modes since the Antiquity. The purpose of the research was therefore to try to map the psychological aspects of the selected intervals and to verify whether the respondents agreed on them. In contrast to similar research testing tempered intervals, here we are dealing with precisely tuned concords of characteristic intervals of just intonation systems (5-limit and 7-limit just intonation), realized in the form of sustained drones. The results of this research show that listening to isolated sustained concords can induce a wide range of responses in the listener, which are identical or similar for a significant number of respondents. Moreover, in some cases, the reactions to a given interval/emotion combination coincide or resemble the characteristics given by Indian or European traditions. All the results of the research have been summarized in a table which can serve practical purposes.

Impact of circadian clock dysfunction on human health
Authors: Samanta Saptadip , Ali Sk Asif
Published: September 2022

All living organisms exhibit circadian rhythms. Humans show circadian rhythm of the different physiological functions such as sleep-wake cycle, core body temperature, feeding behavior, metabolic activity, heart rate variability, hormone secretion, and others. The hypothalamic suprachiasmatic nucleus (SCN) acts as a primary circadian pacemaker. Peripheral tissues have an endogenous circadian clock; however, SCN synchronizes the circadian activity of the peripheral clocks. The retinohypothalamic tract (RHT) from retinal ganglionic cells carries the photic signal into the SCN that regulates the rhythmic expression of the core clock genes through the feedback loop. At the output level, the SCN connects with the pineal gland and the peripheral tissues with the help of neuroendocrine mediators. Disruption of circadian clock functions is detrimental to health. Shift work, night work, chronic or acute jet lag, and light-at-night have adverse effects on circadian functions. Misalignment of circadian rhythm alters the expression of core clock genes, leading to deregulation of cellular activity and metabolic functions. Circadian rhythm dysfunction causes many pathologic conditions, including sleep disorders, cardiovascular problems, metabolic dysfunction, infertility, poor physical performance, as well as cancer. The present work has reviewed the relationship between circadian clock dysfunction and impaired physiological activities.

La investigación tuvo como objetivo establecer la relación que existe entre la inteligencia emocional (IE) y la calidad de vida (CV), en una muestra de 261 participantes, 132 varones (50.6%) y 129 de género femenino (49.4%), estudiantes de 4º y 5º de secundaria de dos instituciones educativas de Lima, cuyas edades fluctúan entre 16 y 18 años. El diseño de investigación no experimental, transaccional. Se utilizó la escala de calidad de vida de Olson & Barnes adaptada y el inventario de inteligencia emocional de Bar-On (ICE), y una ficha demográfica. Obtuvimos correlaciones positivas entre la inteligencia emocional y la calidad de vida (r = .40, p<.01), y los factores de la escala de CV, además no se encontraron diferencias significativas entre las correlaciones de IE y CV respecto al género y al centro educativo de procedencia. El análisis de regresión reveló que ninguna de las subescalas de IE, es capaz de predecir por sí sola, pero que el factor compuesto por intrapersonal, interpersonal y estado de ánimo predice la Calidad de Vida de forma directa. Estos hallazgos se corroboran con estudios anteriores de relación entre estas variables.
On the Mass Ratio Distribution of Black Hole Mergers in Triple Systems
Authors: Martinez Miguel A. S. , Rodriguez Carl L. , Fragione Giacomo
Published: September 2022

Observations have shown that the majority of massive stars, the progenitors of black holes (BHs), have on average more than one stellar companion. In triple systems, wide inner binaries can be driven to a merger by a third body due to long-term secular interactions, most notably by the eccentric Lidov–Kozai effect. In this study, we explore the properties of BH mergers in triple systems and compare their population properties to those of binaries produced in isolation and assembled in dense star clusters. Using the same stellar physics and identical assumptions for the initial populations of binaries and triples, we show that stellar triples yield a significantly flatter mass ratio distribution from q = 1 down to q ∼ 0.3 than either binary stars or dense stellar clusters, similar to the population properties inferred from the most recent catalog of gravitational-wave events, though we do not claim that all the observed events can be accounted for with triples. While hierarchical mergers in clusters can also produce asymmetric mass ratios, the unique spins of such mergers can be used to distinguish them from those produced from stellar triples. All three channels occupy distinct regions in the total mass–mass ratio space, which may allow them to be disentangled as more BH mergers are detected by LIGO, Virgo, and KAGRA.

The near-ultraviolet (NUV) spectral region is a useful diagnostic for stellar flare physics and assessing the energy environment of young exoplanets, especially as relates to prebiotic chemistry. We conducted a pilot NUV spectroscopic flare survey of the young M dwarf AU Mic with the Neil Gehrels Swift Observatory's UltraViolet and Optical Telescope. We detected four flares and three other epochs of significantly elevated count rates during the 9.6 hr of total exposure time, consistent with a NUV flare rate of ∼0.5 hr−1. The largest flare we observed released a minimum energy of 6 × 1033 erg between 1730 and 5000 Å. All flares had durations longer than the ∼14–17 minutes duration of each Swift visit, making measuring total flare energy and duration infeasible.

Authors: Khan Aijaz A. , Vijay Anuj , Wani Shaqul Qamar , Haq Malik M.
Published: September 2022

Purpose: Intracavitary brachytherapy is one of the important methods of gynecological cancer treatment. The effect of attenuation is not considered in the dose calculation method released by the American Association of Physicists in Medicine (AAPM) Task Group No. 43 Report (TG-43). In this study, the effect of high-dose rate (HDR) brachytherapy applicators on dose distribution was measured using Gafchromic films and well-type ionization chamber. Materials and Methods: A plan created by the treatment planning system was first executed using a well-type ionization chamber with a water equivalent elasto-gel in place for charge collection. Again, same plan was executed using central tandems of various angulations with different diameters of vaginal cylinders and charge collection was measured. For in vitro dose measurements this plan was also executed on tandem and vaginal cylinder assembly with Gafchromic films fixed on the surface of vaginal cylinder. Results: The results show that the central tandem when used with different vaginal cylinders resulted in increase in effective attenuation of the beam. The central tandem of 300 angulations when used with a 35-mm diameter vaginal cylinder results in maximum attenuation whereas the 0º tandem when used with 20-mm diameter vaginal cylinder results in least attenuation of the beam. Conclusion: Due to the attenuation by various applicators used in brachytherapy for the treatment of gynecological cancers, it can be concluded that the difference between practical dose and the treatment planning system calculated dose should be considered for the correct estimation of the dose to the target and the organs-at-risk.

Published: September 2022

BACKGROUND: Reactive oxygen species and cytokines are the main players in the development of renal ischemia-reperfusion (I/R) injury.

AIM: The current study aimed to evaluate the effects of carvedilol and/or glibenclamide and the interaction between autophagy and oxidative stress.

METHODS: 50 male rats were divided into five groups: Control, IR injury (IRI), carvedilol pretreated, glibenclamide pretreated, and combined carvedilol and glibenclamide pretreated. Measurements of renal blood flow (RBF), creatinine clearance, serum blood urea nitrogen (BUN), histopathological, and immunohistochemical evaluation of autophagy marker Becl-1 in the rat kidney were performed. Beclin-1and light chain 3 (LC3) Mrna expression was detected by real time polymerase chain reaction.

RESULTS: IRI was associated with significant increases in BUN, tumor necrosis factor-alpha, nuclear factor κB, and histo (H) score value of Becl-1. However, there was a significant decrease in RBF, creatinine clearance, and glutathione peroxidase compared to the control group. There was significant increase in Beclin-1 and LC3 mRNA gene expression in carvedilol, glibenclamide, and combined treatment groups as compared to IRI and control groups. Combination of carvedilol and glibenclamide significantly restored IRI changes when compared with the other pretreated groups.

CONCLUSION: This study suggests that carvedilol and glibenclamide are promising reno-protective drugs to reduce renal injury induced by I/R through their antioxidant and autophagy stimulation.

Background and Aim: Although implantation of a care bundle approach is well established in intensive care units (ICUs), yet its impact on reducing surgical site infections (SSI) among post living-donor-liver transplantation (LDLT) patients has not been established. Our aim is to evaluate the impact of a care bundle in reducing SSI and to detect the pattern of antibiotic resistance in LDLT. Materials and Methods: This before and after comparative study was conducted at Elmanial specialized tertiary hospital, Cairo University over a period of 3 years (January 2016 - December 2018) including 57 LDLT patients. We introduced a care bundle comprised of a group of evidence-based practices implemented together. The study was divided into three phases. All bacterial identification and antibiotic sensitivity testing were done by a Vitek 2 compact system. Results: SSIs rates were reduced significantly by 30.4% from the pre-implementation to the post implementation phase (from 13/24, 54.2% to 5/21, 23.8%, OR 0.21, CI 95%: 1.137- 0.039). This reduction went hand in hand with increase in the hand hygiene compliance from 57.3 % to 78 %, then remained sustained with a median rate of 78% in the last 6 months. Klebsiella pneumoniae 11\25 (44% of SSIs), Acinetobacter baumannii 8\25 (32% of SSIs), Escherichia coli 5\25 (20%), Pseudomonas aeruginosa 5\25 (20%) and MRSA 4\25 (16%). With predominance of XDR phenotype 14/25 (56%), followed by ESBL of gram-negative bacteria 6/25 (24%), then MRSA 4/25 (16%). Conclusion: SSIs in LDLT mandates strict implementation of comprehensive evidence-based care bundles for better patent outcome.

BACKGROUND: Stunting is an adverse result condition of unfulfilled nutritional intake during pregnancy and early childhood, which affects the children’s maximum height and optimal cognitive potential. Stunting is influenced by numerous factors, both from the mother and children. Research has proven that factors related to mothers of children under 5 have essential roles in the incidence of stunting.
AIM: This study intends to analyze the influence of maternal risk factors on the incidence of stunting in children under 5 in districts/cities in South Sumatra.
METHODS: This study is quantitative research with a cross-sectional design, with secondary data sources from Basic Health Research 2018, carried out in 17 districts/cities in South Sumatra.
RESULTS: The mothers’ characteristics most significantly related to stunting in children under 5 in the South Sumatra region are the mother’s height and mother’s education. Mothers with a height <150 cm have a 1.547 times higher risk of having stunting children (95% CI: 1.281–1.868), and mothers with low education have a 1.521 times higher risk of having stunting children (95% CI: 1.094–2.116). Moreover, mothers with secondary education are at 1.473 times higher risk of having stunting children (95% CI: 1.073–2.020).
CONCLUSION: The maternal risk factors most associated with stunting in children under five in South Sumatra are maternal height and mother’s education.
Comments about the “Systematic Review: Physical Rehabilitation Therapy for Long COVID-19 Patient with Respiratory Sequelae”
Authors: Toulgui Emna , Benzarti Wafa , Saad Helmi Ben
Published: September 2022

I read with great interest the systematic review of Prabawa et al. “Physical Rehabilitation Therapy for Long COVID-19 Patient with Respiratory Sequelae: A Systematic Review”. The rational of this systematic review is very interesting, since it discusses the rehabilitation therapy for long coronavirus disease 2019 (COVID-19) syndrome with respiratory sequelae. In COVID-19, physical rehabilitation is a new management axis, and studies related to its impacts on COVID-19 patients’ data are scarce. In their paper, Prabawa et al. have included one Tunisian study (Benzarti W, et al. General practitioners should provide the cardiorespiratory rehabilitation’ ‘minimum advice’ for long COVID-19 patients. Lib J Med. 2022;17(1):2009101) published by the authors of this correspondence. However, three remarks related to the following points were noted: i) Citation of a wrong country of Benzarti et al., ii) Publishing a figure belonging to Benzarti et al. without obtaining the authors’ permission, and iii) Omission to develop a chapter for nutrition rehabilitation. The present Letter to Editor is an appeal for a more rigor when reporting data from previous publications (eg; avoid mistakes related to the country of the first author), and is a remain that permission is needed if some authors want to use a figure created by somebody else.

Authors: Shalaby Adel , Al-Gholam Marwa , Elfiky Safa , Elgarawany Ghada
Published: September 2022

BACKGROUND: Diabetes mellitus is a chronic metabolic disorder, affected by fructose, and artificial sweeteners. Aspartame and fructose are popularly used, by diabetics, as substitutes to glucose.

AIM: This study evaluated the effect of high aspartame and fructose on vascular reactivity, glucose, and hepatic metabolism in diabetic rats.

MATERIALS AND METHODS: Forty-eight male rats were divided into six groups: Control, control-diabetic, aspartame, aspartame-diabetic, fructose, and fructose-diabetic. After 60 days, blood pressure, vascular reactivity to norepinephrine, Lipid profile, fasting glucose, insulin, homeostasis model assessment of insulin resistance (HOMA-IR), leptin, and Malondialdehyde (MDA) were measured.

RESULTS: High aspartame alone or with diabetes, decreased leptin, vascular reactivity, and increased triglyceride, cholesterol, MDA, and fasting blood glucose. Hepatic tissues showed dilated congested vessels, cellular infiltration, decreased Periodic Acid Schiff’s reaction, and increased collagenous fibers. High fructose decreased leptin, high-density lipoprotein, vascular reactivity, and increased cholesterol, Low-density lipoprotein, MDA, glucose, and HOMA-IR. Hepatic tissues showed more fatty infiltration, glycogen deposition, and increased collagenous-fibers. The condition became worse in diabetes-treated rats.

CONCLUSION: High aspartame and high fructose diet caused deleterious effects on diabetic rats by atherogenic, oxidative stress, vascular, glucose, and hepatic tissue metabolism impairment.

Authors: Santi Dwi Rukma , Suminar Dewi , Devy Shrimarti Rukmini , Mahmudah Mahmudah , Soedirham Oedojo , Prasetyorini Anif
Published: September 2022

Background:
Approximately 10.7 million pregnant women have passed away from 1990 to 2015 due to obstetric complications. Nearly all of them (99% of global maternal deaths) take place in developing countries. As a matter of fact, most people in dveloping countries have implemented many cultural practices which bring about negative effects on pregnant women’s health behaviour to potentially have greater risk of obstetric complications. Unfortunately, no comprehensive research yet conducted especially on pregnant women’s perceptions of pregnancy, childbirth, and postpartum care (PC) in developing countries.   
 
Objective:
To identify factors of pregnant women’s perception of pregnancy, childbirth, and postpartum care in developing countries
 
Method:
The research was carried out through Literature Review in which electronic database search the so-called database Science Direct, PubMed, Elsevier (SCOPUS), Springerlink, and Google Schoolar was conducted in January 2021. The steps of systematic review were through Preferred Reporting Items for Systematic Reviews and Meta-analyses (PRISMA) method.
 
    Results:
Modifying factors with pivotal role during the service of pregnancy, childbirth, and postpartum care in developing countries are knowledge, ethnicity, socioeconomics, and personality. Most individual beliefs in developing countries are perceived barriers. Whereas, Perceived susceptibility and severity of disease, perceived benefits, perceived self efficacy and perceived threat to make the most use of health service during pregnancy, childbirth, and postpartum care are also well-known with variables of external cues to action is among the most popular ones especially with personal experience and information from neighborhood with local habits and belief unsupportive to health service.
 
Conclusion:
Factors to influence perception, practice, and access during pregnancy, childbirth, and postpartum care in developing countries are culture, knowledge, distance, education, experience, mental stress, no decision making autonomy and social supports. Thus, comprehensive research on the influence of modifying factors of individual behavior and cues to action needs to be carried out.

Published: September 2022

Ag3PO4 was prepared by the precipitation method using monobasic/dibasic phosphate salts (K2HPO4, KH2PO4, Na2HPO4, NaH2PO4) as a precipitating agent. The environment created by the precursor salts strong affected on the crystallinity and the morphology of Ag3PO4. Ag3PO4 synthesized from dibasic phosphate salts exhibited pseudospherical morphology and small particle size while monobasic phosphate salts promoted crystallization, resulting in a large grain size and a very diverse grain morphology. Ag3PO4 prepared from dibasic phosphate salts (K2HPO4 and Na2HPO4) exhibited superior photocatalytic ability, completely degrading rhodamine B (RhB) in 8 min and 10 min under Xenon lamp irradiation, respectively. This result once again confirms the necessity of particle size reduction in the production of photocatalysts.

Published: September 2022

In this paper, we will present a collocation approach based on barycentric interpolation functions and finite difference formulation to study the approximate solution of nonlinear Schrödinger equation. We discretize the time derivative by Crank-Nicolson scheme and bring barycentric interpolation functions into action for spatial discretization. Furthermore, consistency analysis of semi discrete collocation scheme is given. For the nonlinear term, we use Newton iterative method to derive the corresponding linear algebraic equations. Finally, numerical examples show that the numerical scheme has high precision and satisfies the mass and energy conservation.
GCS-YOLOV4-Tiny: A lightweight group convolution network for multi-stage fruit detection
Authors: Huang Mei-Ling , Wu Yi-Shan
Published: September 2022

Fruits require different planting techniques at different growth stages. Traditionally, the maturity stage of fruit is judged visually, which is time-consuming and labor-intensive. Fruits differ in size and color, and sometimes leaves or branches occult some of fruits, limiting automatic detection of growth stages in a real environment. Based on YOLOV4-Tiny, this study proposes a GCS-YOLOV4-Tiny model by (1) adding squeeze and excitation (SE) and the spatial pyramid pooling (SPP) modules to improve the accuracy of the model and (2) using the group convolution to reduce the size of the model and finally achieve faster detection speed. The proposed GCS-YOLOV4-Tiny model was executed on three public fruit datasets. Results have shown that GCS-YOLOV4-Tiny has favorable performance on mAP, Recall, F1-Score and Average IoU on Mango YOLO and Rpi-Tomato datasets. In addition, with the smallest model size of 20.70 MB, the mAP, Recall, F1-score, Precision and Average IoU of GCS-YOLOV4-Tiny achieve 93.42 ± 0.44, 91.00 ± 1.87, 90.80 ± 2.59, 90.80 ± 2.77 and 76.94 ± 1.35%, respectively, on F. margarita dataset. The detection results outperform the state-of-the-art YOLOV4-Tiny model with a 17.45% increase in mAP and a 13.80% increase in F1-score. The proposed model provides an effective and efficient performance to detect different growth stages of fruits and can be extended for different fruits and crops for object or disease detections.
