Abstract
The ability to conduct en-route centrifugation of samples improves quality and timeliness in the pre-analytical phase. This is demonstrated here on a quadcopter whereby the propellers were adapted to house and apply centrifugal forces to sample-containing capillary tubes instead of incorporating a centrifuge. Tests revealed the ability of the method to separate non-homogenized milk into a cream portion and a skim milk portion, and human whole blood into plasma, buffy coat, and red blood cell components.

Abstract
Background: Retinoblastoma is most common intraocular malignancy of infancy. Globally screening is recommended for ‘at risk’ children. Despite knowing this, Indian Cancer Society undertook general screening at behest of a corporate donor. Scenario in India is challenging as children at rural, urban slums are not routinely screened for any of eye disease. ICS implemented the pilot project among underprivileged children with primary aim of spreading awareness and improve the ocular health. Though expected outcome was zero retinoblastoma suspect cases; based on past projects it was expected that other eye conditions like squint, cataract etc. would be identified in a few. Aim: To screen 4500 children below 4 years of age at Indian rural and suburban slum areas. To create awareness about retinoblastoma and other eye conditions in community. Methods: Locations were identified where literacy, awareness, immunization coverage were low. Partners were selected a team of experts (ocular oncologists, pediatric ophthalmologists, optometrists, paramedical staff) were deployed for implementation. For awareness, all parents coming for the immunization, Aaganwadis and preschools etc. were given a talk on the importance of child eye screening and various disease which can be detected and prevented through simple eye examination. Special community level programs planned to create awareness about retinoblastoma and early childhood eye screening. Brochures and pamphlets were to be given in the vernacular language of the region. Screening for retinoblastoma was planned in 2 phases, those found to have positive red reflex in stage 1 are subjected to dilation, after obtaining consent from the parents. Proformas were filled in and treatment was given as per the pediatric eye disease identified. Results: In 5 months 2450 children were screened, at tribal area and in suburban slum areas. Awareness sessions were conducted for 348 mothers in batches at the tribal area and similarly for mothers and teachers at Anganwadi, schools. None of the parents/teachers were aware about cancer of eye. A thorough eye check-up was done based on the suggestions of the American Association of Pediatric eye diseases and special attention was given to tests such as Bruckners test. Number of children suspected of retinoblastoma was nil, however, 6% children were found to have other eye conditions such as congenital cataract, corneal opacity, refractive errors, squints and ptosis in the tribal area and project is ongoing in suburban area. Treatment was given as per the protocol for same. Conclusion: Screening for retinoblastoma for not at risk children is not recommended. Main aim for implementing retinoblastoma awareness program is to integrate it with immunization or nutritional program in India. This would ensure standardized ocular care. Challenges are numerous, such as lack of infrastructure, poor literacy rates, low income levels. Yet, innovative strategies are needed for better impact of awareness programs.

WATER RESOURCES RESEARCH 2018; 54:5422-5435.

Abstract
Uncertainties in hydro-climatic projections are (in part) related to various components of the production chain. An ensemble of numerous projections is usually considered to characterize the overall uncertainty; however in practice a small set of scenario combinations are constructed to provide users with a subset that is manageable for decision-making. Since projections are unavoidably uncertain, and multiple projections are typically informationally redundant to a considerable extent, it would be helpful to identify an informationally representative subset in a large model ensemble. Here a framework rooted in the information theoretic Maximum Information Minimum Redundancy concept is proposed for identifying a representative subset from an available ensemble of hydro-climatic projections. We analyze an ensemble of 16 precipitation and temperature projections for Sweden, and use these as inputs to the HBV hydrological model to project river discharge until the mid of this century. Representative subsets are judged in terms of different statistical properties of three essential climate variables (precipitation, temperature and discharge), whilst we further assess the sensitivity of the optimized subset for different seasons and future periods. Our results indicate that a quarter to a third of the available set of projections can represent more than 80% of the total information of hydro-climatic changes. We find that the representative subsets are sensitive to the regional hydro-climatic characteristics and the choice of variables, seasons and periods of interest. Therefore we recommend that any selection process should not be solely driven by climatic variables but, rather, should also consider variables of the impact model.

Abstract
We present a new image reconstruction method that replaces the projector in a projected gradient descent (PGD) with a convolutional neural network (CNN). Recently, CNNs trained as image-to-image regressors have been successfully used to solve inverse problems in imaging. However, unlike existing iterative image reconstruction algorithms, these CNN-based approaches usually lack a feedback mechanism to enforce that the reconstructed image is consistent with the measurements. We propose a relaxed version of PGD wherein gradient descent enforces measurement consistency, while a CNN recursively projects the solution closer to the space of desired reconstruction images. We show that this algorithm is guaranteed to converge and, under certain conditions, converges to a local minimum of a non-convex inverse problem. Finally, we propose a simple scheme to train the CNN to act like a projector. Our experiments on sparse-view computed-tomography reconstruction show an improvement over total variation-based regularization, dictionary learning, and a state-of-the-art deep learning-based direct reconstruction technique.

Abstract
Multifunctional sensors responding to different chemical stimuli fabricated using functional nanomaterials still remain a challenge because of the usage of the same sensor multiple times for different sensing applications and unreliable front-end processing of the sensing data. This challenge is intensified by the lack of suitable techniques for fabricating disposable sensors, which can be integrated into smartphones with a dedicated application developed for each sensing application. A novel MoS2/Cu2S hybrid grown on disposable cellulose paper by the hydrothermal method is reported for its utilization in sensing humidity, temperature, breath, and ethanol adulteration, wherein the data can be wirelessly transmitted to a smartphone with the dedicated application module for each sensing application. The sensor can be utilized for a particular sensing application and then can be disposed, avoiding the need for utilizing the same sensor for different sensing applications, thereby increasing the accuracy of the sensing data. The sensing mechanism of the fabricated sensor is explained for each stimulus in terms of change in the transport properties of the MoS2/Cu2S hybrid. The development of such unique hybrid materials for wireless disposable multifunctional sensors is a great step ahead in flexible and wearable electronics having potential applications in medical, security, Internet of things, etc.

Abstract
Objectives To determine if quantitative and qualitative shear wave elastography have roles in evaluating musculoskeletal masses. Methods 105 consecutive patients, prospectively referred for biopsy within a specialist sarcoma centre, underwent B-mode, quantitative (m/s) and qualitative (colour map) shear wave elastography. Reference was histology from subsequent biopsy or excision where possible. Statistical modelling was performed to test elastography data and/or B-mode imaging in predicting malignancy. Results Of 105 masses, 39 were malignant and 6 had no histology but benign characteristics at 12 months. Radiologist agreement for B-mode and elastography was moderate to excellent Kw 0.52-0.64; PABAKw 0.85-0.90). B-Mode imaging had 78.8% specificity, 76.9% sensitivity for malignancy. Quantitatively, adjusting for age, B-mode and lesion volume there was no statistically significant association between longitudinal velocity and malignancy (OR [95% CI] 0.40[0.10, 1.60], p=0.193), but some evidence that higher transverse velocity was associated with decreased odds of malignancy (0.28[0.06, 1.28], p=0.101). Qualitatively malignant masses tended to be towards the blue spectrum (lower velocities); 39.5% (17/43) of predominantly blue masses were malignant, compared to 14.3% (1/7) of red lesions. Conclusions Quantitatively and qualitatively there is no statistically significant association between shear wave velocity and malignancy. There is no clear additional role to B-mode imaging currently. Key Points • Correlation between shear wave velocity and soft tissue malignancy was statistically insignificant • B-mode ultrasound is 76.9 % sensitive and 78.8 % specific • Statistical models show elastography does not significantly add to lesion assessment

Abstract
Background: Argyreia nervosa (Convolvulaceae) plant is an example of hallucinogenic plant. The antiseptic, anti-inflammatory, antispasmodic, antibacterial, antiviral, antifungal, anticonvulsant, nootropic, antifertility and aphrodisiac properties have already been reported for this plant. Aim: The aim of present work was to evaluate the wound healing property in normal and diabetic animals by oral and topical administration of ethanolic extract of leaves. Materials and Methods: Phytochemical investigations showed the presence of various biochemicals (alkaloids, flavonoids, carbohydrates, triterpenoids, proteins, saponins, steroids, tannins). A single injection of alloxan monohydrate (120 mg/kg, i.p.) prepared in citrate buffer (0.1 M, pH 4.5) was administered to produce diabetes in rats and mice, after overnight fasting. Excision wounds (sized 300 mm2 and of 2 mm depth) were used for the study of rate of contraction of wound and epithelization. The means of wound area measurement between groups at different time intervalswere compared using one-way analysis of variance (ANOVA), followed by Dunnet's test. Results: Extracts of A. nervosa showed significant wound healing effect in normal (topically treated) and diabetic (both topically and orally treated) rats. In diabetic rats, the topically treated group showed more significant effect than the orally treated groups. Conclusion: The present study demonstrates that A. nervosa leaves extract applied topically promotes healing of wounds more significantly as compared to oral application, in both normal rats and alloxan induced diabetic rats, where healing is otherwise delayed.
