ANALYZING THE AMBIGUITY IN RNA STRUCTURE USING PROBABILISTIC APPROACH

ABSTRACT: RNA is the second major form of nucleic acid in human cells that play intermediary role between DNA and functional protein. Several classes of RNA's are found in cells, each with distinct function. Understanding of storage and utilization of a cell's genetic information is based on the structure of RNA. Many experimental results have shown that RNA plays a greater role in the cells. RNA sequences contains signals at the structure level can be exploited to detect functional motifs common to all or a portion of those sequence. Different types of analysis of a structure can provide functional information in different degrees of detail. In this paper various types of RNA secondary structure representation has been discussed and in which appropriate structure has been adopted for probabilistic approach that shows un-ambiguity

An adaptive and flexible brain energized full body exoskeleton with IoT edge for assisting the paralyzed patients

The paralyzed population is increasing worldwide due to stroke, spinal code injury, post-polio, and other related diseases. Different assistive technologies are used to improve the physical and mental health of the affected patients. Exoskeletons have emerged as one of the most promising technology to provide movement and rehabilitation for the paralyzed. But exoskeletons are limited by the constraints of weight, flexibility, and adaptability. To resolve these issues, we propose an adaptive and flexible Brain Energized Full Body Exoskeleton (BFBE) for assisting the paralyzed people. This paper describes the design, control, and testing of BFBE with 15 degrees of freedom (DoF) for assisting the users in their daily activities. The flexibility is incorporated into the system by a modular design approach. The brain signals captured by the Electroencephalogram (EEG) sensors are used for controlling the movements of BFBE. The processing happens at the edge, reducing delay in decision making and the system is further integrated with an IoT module that helps to send an alert message to multiple caregivers in case of an emergency. The potential energy harvesting is used in the system to solve the power issues related to the exoskeleton. The stability in the gait cycle is ensured by using adaptive sensory feedback. The system validation is done by using six natural movements on ten different paralyzed persons. The system recognizes human intensions with an accuracy of 85%. The result shows that BFBE can be an efficient method for providing assistance and rehabilitation for paralyzed patients. © 2013 IEEE. **Please note that there are multiple authors for this article therefore only the name of the first 5 including Federation University Australia affiliate “Venki Balasubramanian” is provided in this record*

Construction and Performance Analysis of an Indirect Solar Dryer Integrated with Solar Air Heater

AbstractThe use of conventional sources of energy for drying agricultural product is an expensive process in developing countries. Therefore, an appropriate technology for drying of agricultural produce has been developed and its performance for the drying of tomatoes was evaluated. An indirect type natural convection solar dryer was developed. The aim of this study is to evaluate dryer performance under natural and forced convection modes of drying. In natural and forced convection, air mass flow rates of 0.00653kg/s and 0.019kg/s respectively were obtained. Hot air reached an average drying temperature of 45°C in natural convection and 40°C in forced convection. The results obtained from natural and forced convection modes of drying were also compared with open sun drying. The colour, flavour and time required for drying is favorable in solar drying as compared to sun drying

A Randomized controlled trial to assess the effectiveness of group-based Diabetes Self-Management Education (DSME) program on glycemic control and self-care activities among type-2 diabetics in South-East Delhi

Introduction: India has the second-largest population of diabetes globally. The long-term complications due to poor glycemic control are concerning. Diabetes Self-Management Education (DSME) is a fundamental component in managing diabetes better. Objectives: This study was conducted to compare the effectiveness of group-based DSME in achieving glycemic control and improving self-care practices among people with type-2 diabetes as against the usual care. Methods: A non-blinded parallel-arm RCT among adults (? 30 years) diagnosed with Type-2 DM. Written informed consent was taken from each patient before enrollment. The sample size is estimated to be 85 in each arm according to the formula for equivalence design for an RCT. Randomization was done using a computer-generated random number table. The control arm received usual care, while the intervention group received group-based DSME in addition to usual care. At the end of 6 months, the change in glycemic control and self-care activity scores were compared between the two arms. Results: A total of 139 individuals (intervention =69; control =70) were analyzed. The proportion of females (62.1%) was higher than males (37.9%). There was no statistically significant difference at baseline. At end line, HbA1c showed a reduction from 9.3% to 6.9% in the intervention arm (P<0.001), which was greater than that in the control arm (p=0.017). All the self-care components showed a statistically significant improvement, except the medication score. Conclusions: Group-based DSME effectively increases self-care practices among people with diabetes, resulting in better glycemic control

BUCCAL ADHES IVE DRUG DELIVERY S YSTEM: SAFER DELIVERY OF BIOTHERAPEUTICS

The route of administration is critical for any medicine. For decades, the most common dosage forms were either oral or injection. Patients generally preferred oral therapies over injected medications because oral delivery is non-invasive and convenient. Drug delivery by buccal route presents unique advantages that are not available with other modes of administration. Buccal drug delivery is a promising option where common drug administrations (e.g., intravenous, intramuscular) are inapplicable. Recently, it has been shown that many drugs have better bioavailability by buccal route than by oral route. This has been attributed to rich vasculature and a highly permeable structure of the buccal mucosa coupled with avoidance of hepatic first-pass elimination, gut wall metabolism and/or destruction in the gastrointestinal tract. The physiology of the buccal mucosa offers a promising route for non-invasive systemic delivery of biotherapeutics. The present article highlights the advantages, physicochemical factors and formulation related parameters affecting the buccal drug delivery. It also includes a note on polymer used in buccal drug delivery and buccal drug absorption pathways. Key Words: Buccal route, bioavailability, non-invasive, Biotherapeutic

Acute respiratory distress syndrome in Plasmodium vivax malaria. A case-control study of comparison between ARDS and non-ARDS patients in P. Vivax malaria

Background: Plasmodium vivax was conventionally considered to be a benign parasite for centuries but in the recent years have proved to be a virulent parasite causing severe malaria. Acute respiratory distress syndrome (ARDS) is one of such severe complications with a significant morbidity and mortality. The objective of this study was to find the prevalence of ARDS and identify the associated factors that could potentially lead to ARDS in patients with vivax malaria. Methods: A retrospective case-control study was conducted at a tertiary hospital in New Delhi. 329 patients with an established diagnosis of Plasmodium vivax mono-infection were identified using hospital medical records, the associated factors were evaluated and compared to calculate the odds of developing ARDS. All patients were categorized into ARDS cases and non-ARDS controls. Results: The incidence of ARDS was 7% with a female sex predominance (60.86%). Mean urea (71.5 mg/dl), creatinine (2.7 mg/dl), and AST (97.8 units/l) elevation in addition to decreased hemoglobin (7.7 gm/dl) and platelets count (38,217 cells/µl) proved to be significantly associated with ARDS in our study. Conclusions: Plasmodium vivax is a virulent parasite and can cause severe malaria even in the setting of isolated infection. Cytokine mediated diffuse inflammatory response is a postulated pathophysiology causing ARDS

Evaluation of the Amphibian Fauna of the Semi-arid and Arid Grassland Habitats in and around the Mayureshwar, Rehekuri, and Karmala Wildlife Sanctuaries in Maharashtra, India

Few studies document amphibian species composition from arid and semiarid environments. Scatteredbodies of water in the semi-arid and arid landscape around Pune, Maharashtra, India, could be viable amphibian habitats; however; information on amphibians using these bodies of water is not available. In a preliminary study, we assessed the amphibian diversity and population status in three wildlife sanctuaries and surrounding areas near Pune. We also compared the use of artificial and natural ponds by amphibians and surveyed the amphibians for the presence of the chytrid fungus

Kilonova Luminosity Function Constraints Based on Zwicky Transient Facility Searches for 13 Neutron Star Merger Triggers during O3

We present a systematic search for optical counterparts to 13 gravitational wave (GW) triggers involving at least one neutron star during LIGO/Virgo's third observing run (O3). We searched binary neutron star (BNS) and neutron star black hole (NSBH) merger localizations with the Zwicky Transient Facility (ZTF) and undertook follow-up with the Global Relay of Observatories Watching Transients Happen (GROWTH) collaboration. The GW triggers had a median localization area of 4480 deg², a median distance of 267 Mpc, and false-alarm rates ranging from 1.5 to 10⁻²⁵ yr⁻¹. The ZTF coverage in the g and r bands had a median enclosed probability of 39%, median depth of 20.8 mag, and median time lag between merger and the start of observations of 1.5 hr. The O3 follow-up by the GROWTH team comprised 340 UltraViolet/Optical/InfraRed (UVOIR) photometric points, 64 OIR spectra, and three radio images using 17 different telescopes. We find no promising kilonovae (radioactivity-powered counterparts), and we show how to convert the upper limits to constrain the underlying kilonova luminosity function. Initially, we assume that all GW triggers are bona fide astrophysical events regardless of false-alarm rate and that kilonovae accompanying BNS and NSBH mergers are drawn from a common population; later, we relax these assumptions. Assuming that all kilonovae are at least as luminous as the discovery magnitude of GW170817 (−16.1 mag), we calculate that our joint probability of detecting zero kilonovae is only 4.2%. If we assume that all kilonovae are brighter than −16.6 mag (the extrapolated peak magnitude of GW170817) and fade at a rate of 1 mag day⁻¹ (similar to GW170817), the joint probability of zero detections is 7%. If we separate the NSBH and BNS populations based on the online classifications, the joint probability of zero detections, assuming all kilonovae are brighter than −16.6 mag, is 9.7% for NSBH and 7.9% for BNS mergers. Moreover, no more than 10⁻⁴, or φ > 30° to be consistent with our limits. We look forward to searches in the fourth GW observing run; even 17 neutron star mergers with only 50% coverage to a depth of −16 mag would constrain the maximum fraction of bright kilonovae to <25%

Optimasi Portofolio Resiko Menggunakan Model Markowitz MVO Dikaitkan dengan Keterbatasan Manusia dalam Memprediksi Masa Depan dalam Perspektif Al-Qur`an

Risk portfolio on modern finance has become increasingly technical, requiring the use of sophisticated mathematical tools in both research and practice. Since companies cannot insure themselves completely against risk, as human incompetence in predicting the future precisely that written in Al-Quran surah Luqman verse 34, they have to manage it to yield an optimal portfolio. The objective here is to minimize the variance among all portfolios, or alternatively, to maximize expected return among all portfolios that has at least a certain expected return. Furthermore, this study focuses on optimizing risk portfolio so called Markowitz MVO (Mean-Variance Optimization). Some theoretical frameworks for analysis are arithmetic mean, geometric mean, variance, covariance, linear programming, and quadratic programming. Moreover, finding a minimum variance portfolio produces a convex quadratic programming, that is minimizing the objective function ðð¥with constraintsð ð 𥠥 ðandð´ð¥ = ð. The outcome of this research is the solution of optimal risk portofolio in some investments that could be finished smoothly using MATLAB R2007b software together with its graphic analysis
