Real Time Virtual Humans

The last few years have seen great maturation in the computation speed and control methods needed to portray 3D virtual humans suitable for real interactive applications. Various dimensions of real-time virtual humans are considered, such as appearance and movement, autonomous action, and skills such as gesture, attention, and locomotion. A virtual human architecture includes low level motor skills, mid-level PaT-Net parallel finite-state machine controller, and a high level conceptual action representation that can be used to drive virtual humans through complex tasks. This structure offers a deep connection between natural language instructions and animation control

Parameterized Action Representation and Natural Language Instructions for Dynamic Behavior Modification of Embodied Agents

We introduce a prototype for building a strategy game. A player can control and modify the behavior of all the characters in a game, and introduce new strategies, through the powerful medium of natural language instructions. We describe a Parameterized Action Representation (PAR) designed to bridge the gap between natural language instructions and the virtual agents who are to carry them out. We will illustrate PAR through an interactive demonstration of a multi-agent strategy game

Nonlinear Differential Equations Satisfied by Certain Classical Modular Forms

A unified treatment is given of low-weight modular forms on \Gamma_0(N), N=2,3,4, that have Eisenstein series representations. For each N, certain weight-1 forms are shown to satisfy a coupled system of nonlinear differential equations, which yields a single nonlinear third-order equation, called a generalized Chazy equation. As byproducts, a table of divisor function and theta identities is generated by means of q-expansions, and a transformation law under \Gamma_0(4) for the second complete elliptic integral is derived. More generally, it is shown how Picard-Fuchs equations of triangle subgroups of PSL(2,R) which are hypergeometric equations, yield systems of nonlinear equations for weight-1 forms, and generalized Chazy equations. Each triangle group commensurable with \Gamma(1) is treated.Comment: 40 pages, final version, accepted by Manuscripta Mathematic

Impact of maternal determinants in rural areas influencing birth weight of newborn

Background: The birth weight of the newborn determines the health and survival of the newborn. Birth weight depends upon maternal factors such as the nutritional status of the mother, gestational age, multiple gestations, hemoglobin status, weight of the mother, complications of labour such as diabetes, hypertension, seizures, cardiac defects, bleeding manifestations, chronic illness and substance abuse. Methods It's a retrospective study conducted at Tagore medical college and hospital. Data collection was drawn on 100women for the age of the mother at the time of delivery, parity, gestational age, hemoglobin status, the weight of the mother, weight of the newborn, blood sugar, and blood pressure from July 2018- July 2019. Results: In our study low birth weight seems to be associated with anaemic mothers with a significant p-value of 0.00. Also, underweight mothers delivered 71.43% of low birth weight babies, normal, overweight and obese mothers delivered 82.35%, 84.21% and 100% normal weight babies which are statistically significant, represented by a p-value of 0.004 in our study. LBW in mothers of age group 18-24yrs 12(27.27%) in our study is high when compared to babies born between 25-31years 7(15.22%) and 10% in the age group between 32-38yrs

Blood Amino Acid Levels in the Freshwater Crab, <i>Barytelphusa guerini </i> H. Milne Edwards, as a Function of Salinity Adaptation

65-68Total free amino acids varied both qualitatively and quantitatively on adaptation to different salinities. Amino acid content increased in 25 and 100% sea water (SW) and the per cent increase was more in females in both media. While the increase in 100% SW was significant in both the sexes, the increase in 25% SW was significant only in females. Females showed a slight but insignificant increase in the intermediate salinities while a slight but Significant decrease was found in the males in the same salinities. Qualitative variations depended upon the sex and salinity of the medium. More new amino acids appeared in 25 and 100% SW while the new ones appearing at intermediate salinities were few. It is suggested that the concentration of amino acids in the blood and its contribution to the blood osmotic pressure depend more on the osmotic gradient than merely the salinity of the external medium. Importance of the choice of sex in studies on osmoregulation is also proposed .in view of the present findings

Intraoperative Lumbar Drain Placement in Endoscopic Neurosurgical Procedures: Technical Challenges and Complications—A Prospective Observational Study

Background Perioperative placement of lumbar drain (LD) is being increasingly preferred in the endoscopic base of skull procedures to provide optimal surgical conditions. This study aims to determine the incidence of technical difficulties and complications associated with LD placement. Materials and Methods A total of 50 patients undergoing transnasal transsphenoidal surgery were included in the study after obtaining written informed consent. Intraoperatively, LD was placed using an 18-gauge epidural catheter. Technical difficulties in LD placement were assessed by the number of attempts, levels attempted, difficulty in siting catheter, and obtaining free flow of cerebrospinal fluid (CSF). The incidence of complications such as postdural puncture headache (PDPH), meningitis headache, and backache was studied. Results Successful LD placement in the first attempt was obtained in 36% of the patients. Technical difficulties were encountered in 64% of the patients. Despite successful LD placement in 90% of the patients, 32% required manipulations to increase CSF flow. The drain failure rate was 10%. Drainage of >20 to 30 mL of CSF/hour was significantly associated with better surgical conditions (p < 0.05). The incidence of headache was 56% and that of backache was 26%. Headache was significantly related to difficulty in tapping CSF (p = 0.032), and backache was significantly related to the number of attempts (p < 0.001), levels attempted (p = 0.001), and large CSF volume (p = 0.004). There were no incidences of PDPH or meningitis in our series. Conclusion We conclude that the incidence of technical difficulties in LD placement with epidural catheters is high. Use of standard well-functioning LD catheters will assist in improving surgical conditions
