Resistance of wild herbaceous legume to the cowpea aphid, Aphis craccivora Koch (Hemiptera: Aphididae)
Year: 2019

The aphid was reared on three wild herbaceous legumes species namely Crotalaria sphaerocarpa DC, Indigofera charlieriana Schinz, wild cowpea Vigna unguiculata subsp. Spontanea Harms) and cowpea variety "Inia" as a check. Life table parameters were used to assess resistance of the wild legumes against the cowpea aphid. The study showed that population growth and life table parameters differed significantly among legume species indicating variation in the level of cowpea aphid response to different species. Significantly longer pre productive period, reduction in fecundity and survival of the cowpea aphid were observed on I. charlieriana and C. sphaerocarpa indicating levels of resistance. A significant reduction in intrinsic rate of natural increase, net reproductive rate, as well as finite rate of increase occurred between varieties. Generation time and doubling time were also significantly higher on aphids feeding on I. charlieriana and C. sphaerocarpa compared to "Inia" and wild cowpea. The negative effects of I. charlieriana and C. sphaerocarpa on life table parameters of A. craccivora indicate degree of resistance of these species against the aphid opening new line of research.
Are Compact Cities Environmentally Friendly?
Year: 2010

There is a wide consensus among international institutions and national governments in favor of compact (i.e. densely populated) cities as a way to improve the ecological performance of the transport system. Indeed, when both the intercity and intra urban distributions of activities are given, a higher population density makes cities more environmentally friendly because the average commuting length is reduced. However, when we account for the possible relocation of activities within and between cities in response to a higher population density, the latter may cease to hold. Indeed, an increasing density policy affects prices, wages and land rents, which in turn incentivizes firms and households to change place. This reshapes the urban system in a way that may generate a higher level of pollution. Thus, although an increase in compactness is environmentally desirable when locations are given, compactness may not be environmentally friendly when one accounts for the general equilibrium effects generated by such a policy.
THE CONTRIBUTION OF NABAKANTA BARUA'S NOVEL "KAPILIPARIYA SADHU" IN THE FIELD OF ASSAMESE LITERATURE: AN ANALYTICAL STUDY
Year: 2021

Nabakanta Barua, a well revered member of the Assamese literati, contributed to various disciplines of Assamese Literature including poems, novels, songs, articles and children's literature. Nabakanta Barua is revered in the Assamese literature world for his persona as a poet and a novelist. In addition to introducing revolutionary changes to the modern Assamese poetry, Barua has been admired for his contribution in the Assamese Novel literature. He presented Assamese literature with several well written and uniquely avored novels, which were based on real life. While the novels reect the cultural heritage of the author in their chapters, the folk life resonates in the words. Nabakanta Barua encompassed a uniquely untrodden and vast area with his multi genre novels. His writings, which have given Assamese literature more than one path to grow and ourish, provide much to study and to understand. This study attempts to analyze the various elements that has been reected in his novel "Kapilipariya Sadhu" It is a qualitative analysis of the sample both as textual and content.
A Social Neuroscience Perspective on Adolescent Risk Taking.
Venue: Developmental review DR
Year: 2008

This article proposes a framework for theory and research on risk taking that is informed by developmental neuroscience. Two fundamental questions motivate this review. First, why does risk taking increase between childhood and adolescence? Second, why does risk taking decline between adolescence and adulthood? Risk taking increases between childhood and adolescence as a result of changes around the time of puberty in the brain's socio emotional system leading to increased reward seeking, especially in the presence of peers, fueled mainly by a dramatic remodeling of the brain's dopaminergic system. Risk taking declines between adolescence and adulthood because of changes in the brain's cognitive control system changes which improve individuals' capacity for self regulation. These changes occur across adolescence and young adulthood and are seen in structural and functional changes within the prefrontal cortex and its connections to other brain regions. The differing timetables of these changes make mid adolescence a time of heightened vulnerability to risky and reckless behavior.
New Evidence on National Board Certification as a Signal of Teacher Quality
Year: 2018

Using longitudinal data from North Carolina that contains detailed identifiers, we estimate the effect of having a National Board for Professional Teaching Standards (NBPTS) teacher on academic achievement. We identify the effects of an NBPTS teacher exploiting multiple sources of variation including traditional lagged achievement models, twin and sibling fixed effects, and aggregate grade level variation. Our preferred estimates show that students taught by National Board certified teachers have higher math and reading scores by 0.04 and 0.01 of a standard deviation. We find that an NBPTS math teacher increases the present value of students' lifetime income by $48,000.
Conditional Image Generation and Manipulation for User Specified Content
Venue: ArXiv
Year: 2020

In recent years, Generative Adversarial Networks (GANs) have improved steadily towards generating increasingly impressive real world images. It is useful to steer the image generation process for purposes such as content creation. This can be done by conditioning the model on additional information. However, when conditioning on additional information, there still exists a large set of images that agree with a particular conditioning. This makes it unlikely that the generated image is exactly as envisioned by a user, which is problematic for practical content creation scenarios such as generating facial composites or stock photos. To solve this problem, we propose a single pipeline for text to image generation and manipulation. In the first part of our pipeline we introduce textStyleGAN, a model that is conditioned on text. In the second part of our pipeline we make use of the pre trained weights of textStyleGAN to perform semantic facial image manipulation. The approach works by finding semantic directions in latent space. We show that this method can be used to manipulate facial images for a wide range of attributes. Finally, we introduce the CelebTD HQ dataset, an extension to CelebA HQ, consisting of faces and corresponding textual descriptions.
Spatiotemporal Data Fusion in Graph Convolutional Networks for Traffic Prediction
Venue: IEEE Access
Year: 2020

A plethora of information is now readily available for traffic prediction, making an effective use of them enables better traffic planning. With data coming from multiple sources, and their features spanning spatial and temporal dimensions, there is an increasing demand to exploit them for accurate traffic prediction. Existing methods, however, do not provide a solution for this, as they tend to require expertise feature engineering. In this paper, we propose a general architecture for SpatioTemporal Data Fusion (STDF) with parameter efficiency. To make heterogeneous multi source data fusion effectiveness, we separate all data into traffic directly related data and traffic indirectly related data. With traffic indirectly related data as the input to Spatial Embedding by Temporal convolutiON (SETON) that simultaneously encodes each feature in both space and time dimensions and traffic directly related data as the input to the graph convolutional network(GCN) we designed a fine grained feature transformer to match the ones generated by GCN. This is then followed by a fusion module to combine all features to make final prediction. Compared to using GCNs training with only traffic directly related data, experimental results show that our model can achieve a 6.1% improvement in prediction accuracy measured by Root Mean Squared Error.
Perioperative chemotherapy with fluorouracil plus leucovorin, oxaliplatin, and docetaxel versus fluorouracil or capecitabine plus cisplatin and epirubicin for locally advanced, resectable gastric or gastro oesophageal junction adenocarcinoma (FLOT4) a randomised, phase 2/3 trial
Venue: The Lancet
Year: 2019

Docetaxel based chemotherapy is effective in metastatic gastric and gastro oesophageal junction adenocarcinoma. This study reports on the safety and efficacy of the docetaxel based triplet FLOT (fluorouracil plus leucovorin, oxaliplatin and docetaxel) as a perioperative therapy for patients with locally advanced, resectable tumours.  In this controlled, open label, phase 2/3 trial, we randomly assigned 716 patients with histologically confirmed advanced clinical stage cT2 or higher or nodal positive stage (cN+ or both, resectable tumours, with no evidence of distant metastases, via central interactive web based response system, to receive either three pre operative and three postoperative 3 week cycles of 50 mg/m2 epirubicin and 60 mg/m2 cisplatin on day 1 plus either 200 mg/m2 fluorouracil as continuous intravenous infusion or 1250 mg/m2 capecitabine orally on days 1 to 21 (ECF/ECX; control group) or four preoperative and four postoperative 2 week cycles of 50 mg/m2 docetaxel, 85 mg/m2 oxaliplatin, 200 mg/m2 leucovorin and 2600 mg/m2 fluorouracil as 24 h infusion on day 1 (FLOT; experimental group) The primary outcome of the trial was overall survival (superiority) analysed in the intention to treat population.  Between Aug 8, 2010, and Feb 10, 2015, 716 patients were randomly assigned to treatment in 38 German hospitals or with practice based oncologists. 360 patients were assigned to ECF/ECX and 356 patients to FLOT. Overall survival was increased in the FLOT group compared with the ECF/ECX group (hazard ratio [HR] 0*77; 95% confidence interval [CI; 0.63 to 0*94] median overall survival, 50 months [38*33 to not reached] vs 35 months [27*35 to 46*26] The number of patients with related serious adverse events (including those occurring during hospital stay for surgery) was similar in the two groups (96 [27% in the ECF/ECX group vs 97 [27% in the FLOT group) as was the number of toxic deaths (two <1% in both groups) Hospitalisation for toxicity occurred in 94 patients (26% in the ECF/ECX group and 89 patients (25% in the FLOT group.  In locally advanced, resectable gastric or gastro oesophageal junction adenocarcinoma, perioperative FLOT improved overall survival compared with perioperative ECF/ECX.
Usage of information system for discovering tax evasion: Case study of Croatia
Year: 2009

This paper explores what data sources should be used for discovering tax evasion with the usage of information system and how the results should be disseminated on the case of Croatian taxpaying scheme. Information systems are very efficient in discovering tax evasion. Although there is wealth of decision support methods (e.g. data mining, on line analytical processing, reporting) for discovering tax evasion, they are not yet used in practice to enough extent. The reason is poor organization of the usage of decision support systems. If usage of information systems is organized more efficiently in terms of better dissemination of the results, more tax evasions would be discovered. The paper explores two issues on the case of Croatian taxpaying scheme. First, it defines what data from the tax information system should be used for discovering tax evasion. Second, it defines the role of the 'data manager' that should sustain fluent cooperation between clerks and information system specialists and more efficient dissemination of the results. We propose a prototype organization of information system for Croatian taxpaying scheme. Specific problems for the Croatian taxpaying scheme are explored, but the proposed system could be useful in other countries as well. In the time of financial crisis and economic depression tax payers have strong tendency toward tax evasion. Therefore, in such conditions it is even more important to have efficient tax collecting system.
Growth of TiO2 coating on wood surface using controlled hydrothermal method at low temperatures
Year: 2010

This paper examines the growth of anatase TiO 2 coating on a wood surface through the hydrolysis of tetrabutyl orthotitanate (TBOT) in different conditions, using a controlled hydrothermal method at low temperatures. Energy disperse X ray analysis and Fourier transform infrared spectroscopy analysis confirm that the growth of TiO 2 coating on a wood surface is bonded to hydrocarbon chains. Several reaction factors that influence the morphologies and amount of TiO 2 present on wood surface were also investigated. As observed from the scanning electron microscopy images, the morphology and content of TiO 2 grown on a wood surface could be controlled under appropriate reaction conditions. Approximately 32.6% TiO 2 content on a wood surface could be obtained when specific conditions are applied.
Sleep and obesity in children and adolescents.
Venue: Pediatric clinics of North America
Year: 2011

The purpose of this review is to provide a comprehensive update of epidemiologic studies that have assessed the association between sleep and obesity risk. Data suggest that short sleep is associated with an increased risk for being or becoming overweight/obese or having increased body fat. Late bedtimes are also a risk factor for overweight/obesity. Findings also suggest that changes in eating pathways may lead to increased body fat. Future experimental studies are needed to enhance our understanding of the underlying mechanisms through which sleep may play a role in the development and maintenance of childhood obesity.

Neural dynamics of between speaker convergence during speech conversation: a dual EEG study
Year: 2017

When two people engage in a conversation, their speech tend to converge towards each other. Little is known about the neural mechanisms contributing to this phenomenon. We used the Word Domino task where two speakers take turns in chaining bi syllabic words according to a rhyming rule: the first syllable has to rhyme with the last syllable of the previous word. We developed a robust automatic method to extract quantitative indexes of convergence at the single word pair, with minimal a priori hypothesis, from Mel frequency cepstral coefficients (MFCCs) A data driven, text independent, automatic speaker identification technique, based on GMM UBM (Gaussian Mixture Model Universal Background Model) was used to extract convergence. The Gaussian components model the underlying broad phonetic features that characterize a speaker's voice. Each speaker dependent models was tested on speech produced by their conversational partners. Model goodness of fit define the convergence index. Dual EEG (Electroencephalography) was recorded to search for the neural underpinnings of speech convergence. This was done by splitting the neural signals of both the speaker's 500ms 0ms before speech onset) and listener's (0ms 500ms during listing) brain into convergent and non convergent epochs. Convergence induced significant desynchronization in the speaking brain in the 12 14 Hz band 270ms to 190ms before speaking onset, in a fronto central anterior scalp region (F5 FC5 FT7 F7) The listening brain showed desynchronization in the high beta band (24 29 Hz; 32 34 Hz) with a left (F3 F5 F7 FC5 FC3 C3 C5) and right (AF8 F6 F8 FT8 FC6) fronto central scalp topography between 50ms and 100ms after listening onset. This results demonstrate that low and high beta oscillatory dynamics contribute to the emergence of speech convergence. Topography suggests the involvement of partially lateralized fronto central regions possibly including Broca's area. Our hyperscanning approach offers insight on the inter brain neural dynamics at play in natural conversation.

Hybrid ultrasonic and mini motor vibration induced irregularly shaped powder delivery for multiple materials additive manufacturing
Year: 2020

Locally dispensing fine and irregular dry powders with a stable and continuous flow rate for additive manufacturing purposes is challenging. Ultrasonic vibration is an effective tool to deposit spherical powders. However, the existing single ultrasonic vibration actuated powder dispenser could cause powder jamming and blockage when dispensing irregularly shaped ceramic particles. In this study, we demonstrate a hybrid ultrasonic and motor vibration integrated dispensing method to successfully deposit irregularly shaped silicon carbide (SiC) powder and SiC and metal powder mixtures. Flow rate experiments on mixed SiC 316 L powders with SiC volume fractions of 25 vol% 40 vol% and 50 vol% indicated that the powder flow rate was determined by powder packing density after pre mixing and before deposition. A lower packing density resulted in a higher powder flow rate. Both the SiC particle size and SiC volume fraction affected the final mixed powder packing density. The SiC 316 L mixture with 40 vol% of 320 grit SiC powder had the highest powder flow rate (37.53 mL/s) Finally, the new powder deposition approach was successfully used for laser powder bed fusion manufacturing of a double helix structure made of a 316 L stainless steel and a SiC 316 L mixture. Such a powder dispensing technology has the potential to be applied in powder materials involved in additive manufacturing and pharmacy industries.
Homemade viral RNA isolation protocol using silica columns: a comparison of four protocols.
Venue: Analytical biochemistry
Year: 2007

The Wrst technique for RNA isolation described in the literature was developed by Chirgwin and coworkers in 1979  They standardized a method for breaking cellular membranes without denaturing nucleic acids through homogenization of tissue in a mixture of guanidinium thiocyanate and mercaptoethanol followed by an ethanol extraction or ultracentrifugation in a cesium chloride gradient. Although this was a signiWcant advance at that time, the technique consumed a lot of time and was ineYcient, hazardous, and inconsistent. With more recent isolation techniques, the quality, speed, and eYciency of this process have improved. In 1987, Chomczynski and Sacchi improved on the Chirgwin method, converting the guanidinium hot phenol method to a single step extraction called the AGPC (acid guanidinium phenol chloroform) method  This modiWcation had at least two beneWts: the possibility of processing more samples simultaneously and the isolation of unbroken RNA with a higher purity and yield. Some years later, in 1993, Chomczynski published a reagent for the single step simultaneous isolation of RNA, DNA, and proteins from cell and tissue samples  Nowadays, there are several nucleic acid isolation kits on the market based on this reagent. More recently, some commercial alternatives have been developed, but it was the development of new techniques employing silica columns for the isolation of nucleic acids
A Shape Representation for Planar Curves by Shape Signature Harmonic Embedding
Venue: 2006 IEEE Computer Society Conference on Computer Vision and Pattern Recognition (CVPR'06)
Year: 2006

This paper introduces a new representation for planar curves. From the well known Dirichlet problem for a disk, the harmonic function embedded in a circular disk is solely dependent on specified boundary values and can be obtained from Poisson's integral formula. We derive a discrete version of Poisson's formula and assess its harmonic properties. Various shape signatures can be used as boundary values, whereas only the corresponding Fourier descriptors are needed for the framework. The proposed approach is similar to a scale space representation but exhibits greater generality by accommodating using any type of shape signature. In addition, it is robust to noise and computationally efficient, and it is guaranteed to have a unique solution. In this paper, we demonstrate that the approach has strong potential for shape representation and matching applications.
