A reconfigurable compliant robotic gripper based on flexible scissors mechanism

Abstract Traditional robotic grippers are constrained by their fixed structures and limited grasping range, which poses difficulties when handling objects of various shapes and sizes. In contrast, reconfigurable grippers can flexibly adjust their grasping mode and configuration based on object properties, enabling them to accommodate a wider range of geometries. However, existing reconfigurable grippers face challenges in achieving structural consistency, large-scale continuous deformation, and ease of manufacturing and operation. To overcome these limitations, this study proposes a reconfigurable compliant robotic gripper (RCRG) based on a flexible scissor mechanism finger (FSMF). The FSMF incorporates an anisotropic scissor unit design that decouples extension and bending motions, achieving up to 4.5 times continuous finger length adjustment. Multiple FSMF modules can be mounted on a rigid scissor mechanism base to form either a two-fingered or three-fingered RCRG, depending on task requirements. With this configuration, the RCRGs can transition from a compact, retracted form to a significantly expanded state by deforming both the base and the FSMFs, thereby reconfiguring the grasping space to accommodate objects of various sizes, shapes, and orientations for diverse tasks. Theoretical modeling and experimental validation were conducted to analyze the mechanical performance of the FSMF under different extension ratios. Various grasping tests results demonstrate that the proposed RCRGs design efficiently and stably handles various objects, with a grasping envelope variation of up to 64 times, showcasing high adaptability and flexibility.

Factors of individual differences between the speeds of the hand and ball during baseball pitching: Assessment of middle finger function based on the hierarchical linear model

ABSTRACT This study aimed to reveal individual differences between the speeds of the hand and ball and clarify the factors affecting those differences. Motion data from 20 highly skilled baseball pitchers, captured using a 16-camera motion analysis system with a sampling frequency of 1,000 hz, were used for correlation and hierarchical linear model analyses. For the hierarchical linear models, the speed of the metacarpophalangeal joint was the independent variable in the 1st level. The independent variables chosen in the 2nd level were the variables regarding the finger length, mean peak angular velocities, and mean peak accelerations of the middle finger joint. Intra-subject correlation analysis showed high positive correlation coefficients between the metacarpophalangeal joint and ball speeds, ranging from 0.803 to 0.992. The difference between the hand and ball speeds ranged from 8.4 m∙s−1 to 12.0 m∙s−1. The hierarchical linear model analyses indicated that the individual differences between the speeds of the hand and ball were partly accounted for by the mean peak accelerations of the proximal and distal interphalangeal joints, suggesting that the force exerted by proximal interphalangeal joint flexion plays an important role in ball speed increment.

Identification of the comparison of the length of the index finger and the ring finger

The length of the index finger (also known as the second finger or 2D finger) and ring finger (also known as the third finger or 4D finger) can be used as identifiable characteristics in humans. The relationship between the ratio of index finger length to ring finger length (2D:4D) is influenced by the hormones testosterone (in men) and estrogen (in women). Where this hormone is a hormone inherited from genes and its expression is influenced by the sex influence gene, so that there is a difference between the length of the index finger and the length of the ring finger. Estrogen and testosterone hormones that will affect the work of HOXD and HOXA in determining the length of a person's fingers. The purpose of the study was to determine the incidence of long index fingers compared to ring fingers in students and female students at SMA Muhammadiyah 1 Padang. This study shows that the difference in length between the index finger and ring finger can vary between individuals. Some studies have also found a correlation between the length of the index and ring fingers with factors such as height and genetic characteristics.

Analysis of Ratio of Length of 2nd Digit to 4th Digit (2D:4D) among Transgender Women (MtF) and Cisgender People in South Indian Population: A Cross-sectional Study

Introduction: Transgender refers to an individual whose gender identity differs from the sex that was assigned at birth. Transgender women (MtF) were assigned male at birth but later recognised themselves as female. The length of the index finger (2D) in males is shorter than the length of the ring finger (4D), resulting in a low finger ratio due to higher androgen levels, whereas in females, the ratio is high due to low androgen levels. The index to ring finger length ratio in males and females is influenced by testosterone hormone levels during early foetal life, exhibiting sexual dimorphism. The 2D:4D ratio serves as one of the determinants for future generations to identify the transgender women population. Aim: To determine the 2D:4D ratio among transgender women and the cisgender population. Materials and Methods: A cross-sectional study was conducted in the Department of Anatomy, Annapoorana Medical College and Hospitals, Vinayaka Mission’s Medical College Hospitals, Salem, Tamil Nadu, India, from September 2018 to October 2019. A total of 392 adult participants between 19 years and 60 years of age were selected. The samples of transwomen were collected with the help of the President of Salem Thirunangaigal Nala Sangam (STNS) and Koovagam Koothandavar Temple in Tamil Nadu. Cisgender samples were collected from volunteers in Salem, Tamil Nadu. The 2D and 4D digit lengths of both hands were measured using Digimizer software with the help of images obtained by a Canon 220 photo scanner. Another type of classification was done by naked eye analysis without any calculations, based on which the 2D:4D ratio among males, females and transgender women was categorised into types 1, 2 and 3. The paired t-test was used to compare the male, female and transwomen populations. Results: Out of 392 participants, 122 were cis females, 130 were cis males and 140 were transgender females. The p-value of the mean 2D:4D ratio was found to be significant in the right and left hands when comparing the 2D:4D ratio of males with females and transgender women with females. The p-value of the 2D:4D ratio for males with transgender women in the right and left hands was 0.451 and 0.943, respectively, which was statistically insignificant due to the high levels of androgen in these two groups. Conclusion: The present study helps scientists in the gender study field to advance their knowledge about transgender individuals, which can fill the gaps in available information and overcome existing lacunae in this field.

An Association Between Left-Hand Digit Ratio (2D:4D) and Anthropometric Indexes in Chinese Children and Adolescents Aged 8-15 Years in Bengbu City.

The digit ratio (2D:4D) is a possible marker of prenatal hormone exposure. The purpose of this study was to explore the relationships between digit ratio (2D:4D) and anthropometric indexes in Chinese children and adolescents. This study is a cross-sectional study. A school-based survey among 685 children and adolescents aged 8-15 years were conducted by stratified cluster sampling. The length of index finger (2D) and ring finger (4D) of the left hand, height, sitting height (ST), weight, chest circumference (CC), waist circumference (WC), hip circumference (HC), and abdominal skinfold thickness (AST) were measured. Pearson correlation and multivariate linear regression were used to analyze associations between 2D:4D and above indexes. In girls, 2D:4D was positively related to WC, AST, waist-to-height (WHtR), waist-to-hip ratio (WHR) after adjusting for ages (p < 0.05). The WC, AST, WHtR, and WHR among girls with 2D:4D ≥ 1 were significantly higher than those among girls with 2D:4D < 1, respectively (p < 0.05). However, there was no correlations between digit ratio (2D:4D) and above anthropometric indexes in boys (p > 0.05). The 2D:4D was related to anthropometric indexes in girls, which suggests that the maternal prenatal hormone exposure might be related to the anthropometric indexes of their female offspring.

Cent-Hydro: A Novel Temperature and Pressure-Controlled Hybrid System for Large-Scale Nanofiber Production

The present study aimed to develop a novel temperature and pressure-controlled hybrid system (Cent-Hydro) for large-scale nanofiber production. Nanofibers from a hydrophilic carrier matrix were prepared using the Cent-Hydro system. This study explores the effect of increasing working temperature on the surface tension and viscosity of polymer solutions. The Cent-Hydro system was calibrated through the process of jet formation, and spinning parameters were identified for the jet path. The formation of fingers in front of the thin liquid occurred due to Rayleigh–Taylor instability, and a lower concentration of polymer solution favoured the development of thinner and longer fingers. The critical angular velocity and initial velocity for jet formation were obtained when the balance between surface tension, centrifugal force, and viscous force was achieved. The effect of increasing rotational speed and working temperature on finger velocity and length was experimentally evaluated, concluding that an increase in working temperature increases finger velocity and length. Additionally, the effect of increasing rotational speed, polymer concentration, and working temperature on the diameter of the nanofiber was evaluated. Overall, the Cent-Hydro system presents a compelling proposition for large-scale nanofiber production, offering distinct advantages over conventional methods and paving the way for advancements in various applications.

Lack of visual experience leads to severe distortions in the hand representation of the body model

This study investigates the impact of vision on the maintenance of hand representation in the implicit body model, particularly focusing on congenitally blind individuals. To address this, we performed a hand landmark localization task on blind individuals who lacked visual experience of their bodies and compared their performance to normally sighted and normally sighted but blindfolded participants. Through measurements of finger lengths, hand width, and shape index, we demonstrate that blind participants exhibit significantly greater distortions in their hand representation compared to sighted and blindfolded controls. Notably, blind individuals displayed a marked overestimation of hand width and an underestimation of finger lengths, particularly in digits D2, D3, and D4. Surprisingly, blind subjects with partial vision displayed more severe distortions than those with no residual vision. Furthermore, our findings reveal that late-blind participants exhibit similar levels of distortion as congenitally blind individuals, suggesting an extended period of susceptibility to the lack of visual input in shaping body representations. The Reverse Distortion (RD) hypothesis provides a plausible explanation for these distortions, suggesting that compensatory mechanisms occur within the body model to counteract the anisotropic cortical representations. Our results support this hypothesis: blind individuals have expanded cortical representations processing tactile information, so this could lead to more pronounced distortions in their hand representation of the body model. This underscores the importance of visual input in modulating body representations. Overall, our study highlights the malleability of body representations and the intricate interplay between sensory inputs and cortical processing in shaping the implicit body model.

DIFFERENCES IN FINGER LENGTH RATIO BETWEEN STUDENTS OF PSYCHOLOGY AND SPECIAL EDUCATION AND REHABILITATION

Background: The disproportionate length of human fingers has generated much interest among researchers. Attention has been drawn to the relationship between the palmar digit (2D:4D) ratio and personality, but the obtained results have been inconsistent. This pilot research project was a qualitative study that aimed to investigate the similarity or differences in the length of fingers 2 and 4 in two groups of students aged 20-21 years from different study programs (psychology and special education and rehabilitation) from Tetova University in Tetova to see if the selection of study program is influenced by the length of certain fingers. Materials and procedure: Single measures of the lengths of the 2nd and 4th digits from the fingertip to the ventral proximal crease of the left and right hand were collected using a ruler calibrated to 0.05 cm. The measurements were anonymous and performed in October of 2023 by the lecturer of teaching subjects in 30 consenting students who participated voluntarily and without any compensation in the participation. At the same time, the data analysis was done statistically using the paired samples test. Results: Means and standard deviations of the parameters with respect to group differences were calculated. We found a nonsignificant group difference in the 2D:4D ratio for the right hand (p=0.402) and for the left hand (p=0.775). Conclusion: Detailed information of finger length parameters and D2:D4 index in a sample study with more participants in the future period will be used from the perspective of neuropsychology.

Assessment of the Vertical Dimension of Occlusion Using Palm Width and Finger Length.

Background and Objectives: The vertical dimension of occlusion's (VDO) assessment is a highly important issue in the everyday dentist's practice. Patients with unstable occlusion, lost occlusal stops, extensive tooth loss in the lateral area, or complete edentulism need a proper assessment of the VDO before the prosthetic restoration is carried out. Subjective and objective methods were used over time for the restoration of VDO. The study aimed to investigate the possible correlation between finger length, palm width and the vertical dimension of occlusion. Materials and Methods: Assessment of the VDO for 236 subjects, Romanian and French dental students, was performed using the Willis Bite Gauge. The left hand of the subjects was scanned using a flat-bed scanner, and then measurements of palm width and finger length were carried out for each subject. Comparison between VDO values and finger length/palm width was conducted using one-way ANOVA and Student t-Test. Results: Higher VDO average values were found in French subjects compared with Romanian students. The same results were found according to gender; in both female and male subjects, lower values of VDO were found in the Romanian group. Higher values were obtained for women within each group when comparing to men. Statistically significant correlations of the analyzed parameters and VDO values were found. Higher statistical correlations of the studied variables were found for men compared to women in both groups. The highest statistical correlation was obtained between the VDO and the palm width measured at the fingerbase, followed by the middle finger length. Conclusions: The results showed the highest statistical correlation between the vertical dimension of occlusion and the palm width measured at the fingers' base. Statistical correlations were also found between the VDO and the middle finger length. Simple formulas using finger length/palm width can be used for a rapid VDO determination.

Correlation between morphometry of fetal foot and gestational age: a cadaver study

Objectives: This study was conducted on a collection of fetal cadavers to describe the relationship between gestational age and foot parameters specifically in the Turkish population. Methods: The study involved 83 fetal cadavers (45 males, 38 females) ranging from 13 to 40 weeks of gestation, without external anomalies or pathologies. Various foot parameters were measured, including foot width (FW), heel width (HW), foot length (FL), heel-metatarsophalangeal fold (HMF), bimalleolar width (BW), foot dorsum length (FDL), ankle-metatarsophalangeal fold (AMF), malleolus medialis height (MMH), malleolus lateralis height (MLH), and finger length (FiL). These parameters were measured using a digital caliper with a precision of 0.01 mm. The fetuses were grouped by gestational month, and morphometric measurements were taken. Results: A strong and positive correlation was found between all foot parameters and gestational age (months). All parameters increased consistently throughout the fetal period. No significant differences were observed based on gender or side comparisons for any of the parameters. Linear regression equations were developed to estimate gestational age using fetal foot parameters. These parameters explained 72% to 90% of the variation in gestational age. Conclusion: Fetal foot length and related foot parameters can reliably be used to estimate gestational age. Due to the simplicity of these measurements, fetal foot parameters can be utilized to estimate age for babies born outside a hospital setting without the need for specialist equipment. Additionally, for premature babies receiving treatment in neonatal units, foot measurements offer a practical and easily accessible method for age estimation.

Evaluation of Digit Ratios in Youth With Polycystic Ovary Syndrome.

Polycystic ovary syndrome (PCOS) is a common syndrome often observed during adolescence, characterized by ovulatory dysfunction and hyperandrogenism. It is determined that, when female fetuses are exposed to high levels of androgens, it increases their likelihood of developing PCOS in later ages. The 2D:4D digit ratio, which measures the length of the index finger compared to the ring finger, is a precise anatomical indicator of the degree of prenatal androgen exposure. Higher digit ratios in individuals have been associated with outcomes typically attributed to females. In the adolescent age group, the relationship between PCOS and androgen exposure during the antenatal period is not clear. The study was aimed to evaluate digit ratios in adolescents with PCOS. The study included 38 adolescent girls with PCOS, and 40 healthy adolescent girls were selected as the control group. The digit ratio (2D:4D) was evaluated by digital calipers, and the digit ratios of the patient and control groups were compared. The mean age in the PCOS group was 15.99±1.18 years, while the control group had a mean age of 16.02±1.06 years. The right-hand 2D:4D digit ratio was significantly lower in the PCOS group (0.93±0.02) compared to the control group (1.00±0.01, p<0.001). Similarly, the left-hand 2D:4D digit ratio was also lower in the PCOS group (0.98±0.03) compared to the control group (1.00±0.01, p<0.001). There was a moderate negative correlation between the left-hand 2D:4D ratio and the modified Ferriman-Gallwey score (mFGS) (r=0.53, p=0.01). Nevertheless, there was not a significant association found between the 2D:4D ratio of the right hand and mFGS. This study demonstrates that PCOS patients have significantly lower both-hand 2D:4D ratios than healthy controls, suggesting prenatal androgen exposure. Recognizing anatomic markers in adolescence may predict the development of PCOS. The findings align with previous research linking low digit ratios to androgen exposure and various reproductive outcomes.

Effect of Different Plant Spacings on Growth, Yield and Disease Incidence in Banana CV. Phule Pride

An investigation was carried out in planted banana crop cv. Phule Pride (AAA) to evaluate the effect of different planting distances on growth, durational, bunch, and yield parameters and disease incidence for three successive years (2021-22 to 2023). The experiment was carried out in Randomized Block Design with four replications. The treatments comprised of T1 (1.20 m x 1.20m (6944 Plants per hectare)), T2 (1.35 m x 1.35m (5487 Plants per hectare)), T3 (1.35 m x 1.75m (4233 Plants per hectare)), T4 (1.50 m x 1.35m (4938 Plants per hectare)) and T5 (1.50 m x 1.50m (4444 Plants per hectare)). In general, there was decrease in pseudo stem height, number of functional leaves and leaf area with the decrease in plant spacing, where increase in pseudo stem girth was observed with the decrease in plant spacing. Delay in all the durational parameters namely days to shooting, days to maturity and days harvesting was recorded with the decrease in plant spacing. Number of hands per bunch, number of fingers per bunch, finger length and bunch weight also decreased with the decrease in plant spacing, whereas increase in finger girth was observed with the decrease in plant spacing. The conventional treatment 1.50 m x 1.50m (4444 Plants per hectare)) recoded highest bunch weight (19.40 t/ha) as against the 12.18 t/ha in the treatment T1 (1.20 m x 1.20m (6944 Plants per hectare). As regards the yield (t/ha), all the treatments were on par with each other except T2 (1.35 m x 1.35m (5487 Plants per hectare). Considering all the parameters, it observed that the plant spacing of 1.5 m x 1.5 m accommodating 4444 plants per hectare is found optimum for the banana cv. Phule Pride.

Application of the Length of Index and Ring Fingers to Estimate the Stature.

Stature contributes as a crucial element of an individual's physical appearance and can be instrumental in establishing their identity.In cases where the body is extensively mutilated, decomposed, or reduced to skeletal remains, stature becomes an essential component in identifying the unknown by means of measuring the skeletal remains. Its estimation relies on the principle that an individual's height has a definite and linear relationship with specific body parts and long bones. This process, together with assessing age, sex, and race constitutes the essential components of the anthropological protocol. Stature estimation can be accomplished through both anatomical and mathematical approaches. The present study clearly defines regression models for height estimation from finger lengths. The formula derived can proveparticularly valuable in Medico-legal scenarios, as it can be applied effectively even when only a portion of the body is accessible. The purpose of the present study is to estimate the stature of individuals by measuring the length of the index and ring fingers. The current study acquired three measurements, such as stature, right/left index finger length (RIFL/LIFL), and ring finger length (RFL), from 220 samples, including 110 males and 110 females, respectively, between the age groups of 20 and 60 years. The application of the length of the index and ring finger in forensic investigations holds significance due to their potential as reliable predictors of an individual's height. According to the findings of the study, males showed significantly higher stature than females. A statistically significant correlation was also observed (p-value = 0) between stature and finger lengths (IFL, RFL) in both hands. The highest correlation coefficients were found for the left RFL (r = 0.688) in females and the LIFL (r = 0.552) in males. Additionally, males showed significantly longer index and RFL than females. Linear regression models for the estimation of stature from ring and index finger length were also derived successfully. The results obtained from the present study exhibit potential use to evaluate the utility of measuring index and RFLs for determining stature and predicting the precision of regression models by employing those parameters. The models derived from this study can serve as corroborative evidence for identifying mutilated body parts or unknown remains.

Effect of Organic Manures Combinations on Yield Attributes of Finger Millet Var. VL Mandua 379

A field experiment was conducted at Himalayan University farm, Itanagar, Arunachal Pradesh, during the kharif season of 2023 with 8 treatments replicated thrice with 24 plots each 3×3 meter in randomized block design, to determine the effect of organic manures on yield of finger millet (Eleusine coracana L.). The experiment included the following treatments T1- Control ,T2- Castor oilcake at 2.5kg/ha+ Poultry manure at 2.5kg/ha,T3- Bone meal at 2.5kg/ha + Poultry manure at 2.5kg/ha,T4- Mustard oilcake at 2.5kg/ha + Goat manure at 2.5kg/ha,T5- Bone meal at 2.5kg/ha + Neem oilcake at 2.5kg/ha + Fym at 2.5kg/ha,T6- Neem oilcake at 2.5kg/ha + Goat manure at 2.5kg/ha, T7- Mustard oilcake at 2.5kg/ha + Poultry manure 2.5kg/ha, and T8- Bone meal at 2.5kg/ha + Goat manure at 2.5kg/ha. All the fertilizers were top dressed on the surface layer of the soil after 1 week of transplantation. The highest finger length (cm) recorded was 6.5 cm at harvest, the highest test weight (g) recorded was 3.1 g at harvest, the highest grain yield recorded was (t ha-1) 4.02 t ha-1 at harvest, highest straw yield (t ha-1) recorded was 7.9 t ha-1 and harvest index (%) 36.78 % at harvest were observed with treatment T5– Bone meal at 2.5kg/ha + Neem oilcake 2.5kg/ha + Fym at 2.5kg/ha.

Rhizobacterial consortium differently affects black leaf spot, physiological, morphological, and productive components in two generations of banana plants

Rhizobacteria's effects on commercial banana plants in different generations remain unclear. In the present field-level investigation, we evaluated the effect of three types (injection, edaphic, and foliar) of applications of a local rhizobacterial consortium on Black leaf spot (BLS), chlorophyll content, morphological components, and fruit production in two generations of commercial banana plants cv. Williams. The rhizobacteria-treated mother and daughter plants received one and two applications, respectively, while the untreated plants constituted the control group. Results of the present investigation indicated that the rhizobacteria differently affect the aerial tissues of different generations of banana plants. Regardless of how the rhizobacteria were applied, they reduced an average of 40 % the BLS incidence on leaves (P ≤ 0.0001) and increased an average 9 % the plant height and pseudostem circumference (P ≤ 0.0001 – P = 0.0475) of mother and daughter plants were observed. However, both morphological variables improved even more in daughter plants edaphically treated with rhizobacteria. Leaf pigments like chlorophyll B (P = 0.0262) and the total content (P = 0.0230) only increased an average of 40 % in daughter plants treated with rhizobacteria. Rhizobacteria edaphic application and injection improved bunch weight (P = 0.0048) and hands per bunch (P ≤ 0.0001) in mother plants. Meanwhile, the edaphic application significantly increased the bunch weight (P = 0.0031), hands per bunch (P = 0.0074), and rachis weight (P = 0.023) by 17% on average in edaphically and foliar-treated mother plants, while the finger length (P = 0.0064) increased by 5% on average. Generally, the morphological and productive components increased much more in daughter plants than in mother. These findings demonstrate the potential of edaphically and foliar rhizobacterial applications to enhance plant health and productivity, providing a sustainable management strategy for banana cultivation.

Effect of biological and chemical application for the control of the red spot vector in banana (Musa paradisiaca L.) crops

The aim of the research was to evaluate the effect of biological and chemical application for the control of the red spot vector in banana (Musa paradisiaca L.). The experimental design was randomized complete blocks (RCB), composed of three treatments, each with 20 experimental units or banana plants. The study was based on two types of red spot control, being chemical control and biologicalcontrol, as well as a referential control. Bowties impregnated with the insecticides were used on the banana bunches. The use of chlorpyrifos was used as chemical control, while for biologicalcontrol a commercial product based on Metarhizium anisopliae 1x109 strains was applied. The study variables were: number of hands, length of fingers, incidence of red spot, percentage of damage, bunch weight, crop yield and cost benefit analysis. The data were statistically evaluated using the analysis of variance and the comparison of measures was carried out using the Tukey test at 5% probability. The results show that there are no significant differences between the treatments that control the red spot of the banana fruit, obtaining 796 boxes of bananas from the chemical control and 787 boxes of bananas from the biologicalcontrol, in the same way the profitability was higher $ 2.24 and $ 2,19 respectively.

Genetic variability, heritability and genetic advance in finger millet (Eleusine coracana L.) genotypes

An investigation was carried out with 101 finger millet genotypes for assessment of genetic variability and heritability in four environments during Kharif 2021. Variation due to genotypes for all the traits under study was found significant suggesting high amount of variability among different genotypes for different traits providing ample scope for selection and further evaluation as well as improvement in the seed yield and its component traits. Grain yield per plant (g) had moderate heritability estimates along with high genetic advance expressed as per cent of mean which implied that the character is controlled by genes having additive nature. High heritability combined with high genetic advance expressed as per cent of mean was noted for the characters viz., main ear head length, finger length, 1000-seed weight, protein content, calcium content, iron content and zinc content. Simple selection for such characters would be rewarding.
