    In this paper we have put forth a novel methodology to relay data obtained by inbuilt sensors of smart phones in real time to remote database followed by fetching of this data . Smart phones are becoming very common and they are laced with a number of sensors that can not only be used in native applications but can also be sent to external nodes to be used by third parties for application and service development

    QIP = PSPACE

    Full text link
    We prove that the complexity class QIP, which consists of all problems having quantum interactive proof systems, is contained in PSPACE. This containment is proved by applying a parallelized form of the matrix multiplicative weights update method to a class of semidefinite programs that captures the computational power of quantum interactive proofs. As the containment of PSPACE in QIP follows immediately from the well-known equality IP = PSPACE, the equality QIP = PSPACE follows.Comment: 21 pages; v2 includes corrections and minor revision

    Background: Recurrent pregnancy loss is a heterogeneous reproductive problem, with multiple etiologies. Objective of this study was to study the incidence of APLA syndrome and low vitamin d levels in RPL and correlation between APLA syndrome and low vitamin D levels.Methods: This was an observational study conducted on 110 women seen in outpatient department/inpatient department of our institution from 1st August 2015 to 31st July 2016 who were known cases of RPL who fitted our inclusion and exclusion criteria.Results: It was found that majority of the RPL patients were in the age group of 30-34 years (42.72%) and they contributed to 43% of the abortions. 77.4% abortions occurred in the gestational age of 6-8 weeks. 21.81% patients were APLA positive. 23.63% patients had  low vitamin D levels. Out of the 21.81% patients who were APLA positive (50%) also had a low vitamin D level which was found to be statistically significant.Conclusions: There appears to be some correlation between APLA syndrome and low vitamin D levels, so both have to be treated simultaneously. Properly investigating women for APLA syndrome and vitamin D deficiency would select a treatable group of women with RPL

    Background: The optimal treatment of complex supracondylar femur fractures remains always challenging and controversial. the purpose of this prospective study was to evaluate the efficacy of distal femoral locking compression plate (DF-LCP) in terms of functional outcome and union rate for highly unstable complex supracondylar femur fractures and to determine the influencing factors of an unfavourable outcome.Methods: After obtaining approval from institutional ethics committee, 45 patients with complex supracondylar femur fractures were managed by open reduction and internal fixation with DF-LCP through lateral approach and as per standard protocol. The follow-up results were analysed clinically and radiologically, using the “Schatzker and Lambert criteria” at once in a month for first three months, once in three months up to one year and once in six months thereafter up to 2 years post-operatively.Results: In the present study, average duration of radiological union was 16 (range 12-22) weeks. The average range of motion of knee joint was 105 degrees. Out of 45 patients, clinical results were excellent in 48.9%, good in 17.8%, fair in 22.2% and poor in 11.1% patients according to Schatzker and Lambert criteria. Knee stiffness (7 cases), secondary arthritis (5 cases), and non-union (4 cases) were the main complications observed in this study, which were treated accordingly.Conclusions: DF-LCP holds the metaphyseal bone strongly and prevents metaphyseal collapse and mal-rotation in complex or highly unstable supracondylar femur fractures and simultaneously, it provides stable fixation to promote fracture union and allows early rehabilitation with acceptable complications

    Background: Congenital idiopathic clubfoot is the most common birth defect of the musculoskeletal system affecting 1 in every 1000 live births each year. Aim of our study was to determine the demographic variables, risk factors associated with CTEV in central India.Methods: A retrospective study was conducted from January 2019 to August 2020 using data of 200 patients with CTEV registered at department of orthopaedics, Netaji Subhash Chandra Bose medical college, Jabalpur, Madhya Pradesh, India were included in our study.Results; Out of total of 200 patients, 167 patients belong to age group <1 year (83.5%) with range from 10 days -7 years. Males were twice (65%) likely affected and (53.5%) clubfoot cases had both feet affected. Right side was more affected in unilateral cases. 189 patients (94.5%) were idiopathic, whereas 11 patients (5.5%) were non-idiopathic. there were 58 (29%) children out of 200, born of consanguineous marriage of parents. Risk factors like anemia, jaundice, asphyxia, obstructed labor, history of miscarriage had positive correlation with clubfoot. CTEV patients of low birth weight <2.5 kg associated with maternal risk factors like smoking, alcohol, anemia.Conclusions: Demographic study is useful tool for determining birth prevalence and risk factors associated with CTEV. There are significantly higher proportion of consanguinity in clubfoot patients. Cultural differences may lead to differences in our findings with respect to the previous studies. These preliminary findings will help in the future for similar studies in central India as well as in the general Indian population

    Schizo-Net: A novel Schizophrenia Diagnosis Framework Using Late Fusion Multimodal Deep Learning on Electroencephalogram-Based Brain Connectivity Indices

    Get PDF
    Schizophrenia (SCZ) is a serious mental condition that causes hallucinations, delusions, and disordered thinking. Traditionally, SCZ diagnosis involves the subject’s interview by a skilled psychiatrist. The process needs time and is bound to human errors and bias. Recently, brain connectivity indices have been used in a few pattern recognition methods to discriminate neuro-psychiatric patients from healthy subjects. The study presents Schizo-Net , a novel, highly accurate, and reliable SCZ diagnosis model based on a late multimodal fusion of estimated brain connectivity indices from EEG activity. First, the raw EEG activity is pre-processed exhaustively to remove unwanted artifacts. Next, six brain connectivity indices are estimated from the windowed EEG activity, and six different deep learning architectures (with varying neurons and hidden layers) are trained. The present study is the first which considers a large number of brain connectivity indices, especially for SCZ. A detailed study was also performed that identifies SCZ-related changes occurring in brain connectivity, and the vital significance of BCI is drawn in this regard to identify the biomarkers of the disease. Schizo-Net surpasses current models and achieves 99.84% accuracy. An optimum deep learning architecture selection is also performed for improved classification. The study also establishes that Late fusion technique outperforms single architecture-based prediction in diagnosing SCZ

    Heat current magnification in Classical and Quantum spin networks

    Full text link
    We investigate heat current magnification due to asymmetry in the number of spins in two-branched classical and quantum spin systems. We begin by studying the classical Ising like spin models using Q2R and CCA dynamics and show that just the difference in the number of spins is not enough and some other source of asymmetry is required to observe heat current magnification. Unequal spin--spin interaction strength in the upper and lower branch is employed as a source of this asymmetry and it proves adequate for generating current magnification in both the models. Suitable physical motivation is then provided for current magnification in these systems, along with ways to control and manipulate magnification through various system parameters. We also study a five spin Quantum system with modified Heisenberg XXZ interaction and preserved magnetisation using the Redfield master equation. We show that it is possible to generate current magnification in this model by the asymmetry in the number of spins only. Our results indicate that the onset of current magnification is accompanied by a dip in the total current flowing through the system. On analysis it is revealed that this dip might occur because of the intersection of two non-degenerate energy levels for certain values of the asymmetry parameter in the modified XXZ model. We deduce that the additional degeneracy and the ergodic constraint due to fixed magnetisation in the system are the main reasons for current magnification and other atypical behaviors observed. We then use the concept of `ergotropy' to support these findings. Finally, for both the classical and quantum models, we see that current magnification is only observed when temperature gradient and intra-system interaction strength have similar order of energy.Comment: 15 pages, 12 figures, extended versio

    Data security is a prime objective of various researchers &amp; organizations. Because we have to send the data from one end to another end so it is very much important for the sender that the information will reach to the authorized receiver &amp; with minimum loss in the original data. Data security is required in various fields like banking, defense, medical etc. So our objective here is that how to secure the data. This study is performed on MATLAB R2016b with standard databasegrey scale images like Barbara, Cameraman and Lenna or by using the personalize images in standard format. First of all, the images are scrambled and then the generation of a new complex image took place. Initially phase mask is applied on the complex image by using RPM 1, and then the complex image is encrypted by using LCT of first order. Again the phase mask RPM 2 is applied on the encrypted image followed by the LCT of second order to get the encrypted image finally. Reverse process is applied to get the original image. Various parameters are calculated which shows various aspects. Like Change in the value of MSE with change in order of transform tells the quality of encrypted image. Correlation coefficient of encrypted and decrypted image also shows the difference between the encrypted and decrypted image. The original image is then reconstructed and histogram of all these images analyzed. Robustness and imperceptibility of images increases by the proposed method
