Quantum Finite Automata and Weighted Automata [article]

M.V. Panduranga Rao, V. Vinay
2007 arXiv   pre-print
Quantum finite automata derive their strength by exploiting interference in complex valued probability amplitudes. Of particular interest is the 2-way model of Ambainis and Watrous that has both quantum and classical states (2QCFA) [A. Ambainis and J. Watrous, Two-way finite automata with quantum and classical state, Theoretical Computer Science, 287(1), pp. 299-311, 2002], since it combines the advantage of the power of interference in a constant-sized quantum system with a 2-way head. This

We consider weighted automata with the Cortes-Mohri definition of language recognition [C. Cortes and M. Mohri, Context-Free Recognition with Weighted Automata, Grammars 3(2/3), pp. 133-150, 2000] as a candidate model for simulating 2QCFA. Given any 2QCFA that (i) uses the accept-reject-continue observable, (ii) recognizes a language with one-sided error and (iii) the entries of whose unitary matrices are algebraic complex numbers, we show a method of constructing a weighted automaton over C that simulates it efficiently.

Giant Enhancement in Ferroelectric Polarization under Illumination [article]

Hitesh Borkar, Vaibhav Rao, M Tomar, Vinay Gupta, J. F. Scott, Ashok Kumar
2017 arXiv   pre-print
We report optical enhancement in polarization and dielectric constant near room temperature in Pb0.6Li0.2Bi0.2Zr0.2Ti0.8O3 (PLBZT) electro-ceramics; these are doubly substituted members of the most important commercial ferroelectric PbZr0.2Ti0.8O3 (PZT:20/80). Partial (40%) substitution of equal amounts of Li+1 and Bi+3 in PZT: 20/80 retains the PZT tetragonal structure with space group P4mm. Under illumination of white light and weak 405-nm near-ultraviolet laser light (30 mW), an unexpectedly

Light also changes the dc conduction current density by one to two orders of magnitude with a large switchable open circuit voltage (Voc ~ 2 V) and short circuit current (Jsc ~ 5x10-8 A). The samples show a photo-current ON/OFF ratio of order 6:1 under illumination of weak light.

A drive in SUVs: From development to disease

Vinay Kumar Rao, Ananya Pal, Reshma Taneja
2017 Epigenetics  
Progression of cells through distinct phases of the cell cycle, and transition into out-of-cycling states, such as terminal differentiation and senescence, is accompanied by specific patterns of gene expression. These cell fate decisions are mediated not only by distinct transcription factors, but also chromatin modifiers that establish heritable epigenetic patterns. Lysine methyltransferases (KMTs) that mediate methylation marks on histone and non-histone proteins are now recognized as

Among these, the SUV39 sub-family of KMTs, which includes SUV39H1, SUV39H2, G9a, GLP, SETDB1, and SETDB2, play a prominent role. In this review, we discuss their biochemical properties, sub-cellular localization and function in cell cycle, differentiation programs, and cellular senescence. We also discuss their aberrant expression in cancers, which exhibit de-regulation of cell cycle and differentiation.

Active Learning for Speech Recognition: the Power of Gradients [article]

Jiaji Huang, Rewon Child, Vinay Rao, Hairong Liu, Sanjeev Satheesh, Adam Coates
2016 arXiv   pre-print
In training speech recognition systems, labeling audio clips can be expensive, and not all data is equally valuable. Active learning aims to label only the most informative samples to reduce cost. For speech recognition, confidence scores and other likelihood-based active learning methods have been shown to be effective. Gradient-based active learning methods, however, are still not well-understood. This work investigates the Expected Gradient Length (EGL) approach in active learning for

Experimentally, we show that EGL can reduce word errors by 11\%, or alternatively, reduce the number of samples to label by 50\%, when compared to random sampling.

Patient with congenital or acquired heart disease comprise a major diagnostic category for Pediatric intensive care units across the country, comprising of 30-40% more admission to some of the centres. Over the last 10 years, there has been a dramatic increase in the use of extracorporeal membrane oxygenation (ECMO) in cardiac failure despite absence of encouraging survival statistics.

Veno-arterial extracorporeal membrane oxygenation (V-A ECMO) is a common modality of circulatory assist used presently in children in our country. This mode can also be used as bridge to heart transplant. This review addresses the following issues for Pediatric Cardiac ECMO: indications and contraindications of VA ECMO, complications, basic ECMO circuit, routine management and management in special circumstances, along with troubleshooting and long term neurological outcome and survival.

Distributed Multigrid Neural Solvers on Megavoxel Domains [article]

Aditya Balu, Sergio Botelho, Biswajit Khara, Vinay Rao, Chinmay Hegde, Soumik Sarkar, Santi Adavani, Adarsh Krishnamurthy, Baskar Ganapathysubramanian
2021 arXiv   pre-print
We consider the distributed training of large-scale neural networks that serve as PDE solvers producing full field outputs. We specifically consider neural solvers for the generalized 3D Poisson equation over megavoxel domains. A scalable framework is presented that integrates two distinct advances. First, we accelerate training a large model via a method analogous to the multigrid technique used in numerical linear algebra. Here, the network is trained using a hierarchy of increasing

In conjunction with the multi-grid approach, we implement a distributed deep learning framework which significantly reduces the time to solve. We show the scalability of this approach on both GPU (Azure VMs on Cloud) and CPU clusters (PSC Bridges2). This approach is deployed to train a generalized 3D Poisson solver that scales well to predict output full-field solutions up to the resolution of 512x512x512 for a high dimensional family of inputs.

A detailed assessment of the anatomy of the entire airway was made and cultures were collected as per the clinical indications. Based on this preliminary assessment, select patients underwent further imaging with computerized tomography (CT) scans and ECHO cardiograms. This was usually indicated with extrinsic compression of the airway was suspected. Gastro esophageal reflux studies were done when clinically indicated. Therapy was individualized; degree of symptoms, nature and degree of airway obstruction and nature of previous airway interventions were primary factors ABSTRACT Aim/Background: Airway anomalies are infrequent but potentially life threatening in children. A program to care for these difficult children was set up at our institution, and this paper summarizes our experience. Methods: A total of 34 children were enrolled in the program over a period of three years. These children were evaluated as per the standard protocols. Treatment was individualized. Results: Of these 34 children, 28 had their airways restored and are doing well. Four children continue to remain on tracheostomy and two will require long term tracheostomy. There were two deaths. All children are under surveillance as there is a risk of recurrence. Conclusions: Airway anomalies are complex problems with significant morbidity and mortality. Current therapeutic modalities allow for good results. Most children were successfully decannulated and did well.

A Bivariate Autoregressive Software Reliability Model

K. Vedavathi, K. Srinivas Rao, A. Vinay Babu
2012 International Journal of Computer Applications  
Software reliability models play a dominant role in the analysis of failure data for real time command and control software systems. Goel and Okumoto model is a non homogenous Poisson Process software reliability growth model which has gained a lot of importance in software reliability analysis and prediction. The process of parameter estimation is the major drawback of this model because the independent nature of attribute values is considered in estimation. But in real world applications,

Keeping this criterion, a bivariate autoregressive model of order 1 which forms a linear combination of variants namely software faults and test workers is proposed. A numerical illustration is presented to evaluate the performance of the developed model with that of the existing univariate autoregressive models and found that the proposed model outperforms than exiting model in evaluating and predicting software reliability.
