Technological Changes and the Distribution of Schooling: Evidence from Green-Revolution in India

In this paper we develop a two-strata general-equilibrium model of human capital acquisition with endogenous school construction that permits an assessment of the relative impacts of technological change and school availability on schooling investments in landless and landed households and illuminates how these choices interact through the adult and child labor markets. A key distinction is made between changes in current levels of agricultural productivity, which directly affect the demand for labor in both landless and landed households, and changes in expected agricultural technology, which only affect the contemporaneous schooling decisions and thus the labor supply of landed children. The implications of the model are assessed using a household-level panel data set which constitutes a representative sample of rural India during the peak period of agricultural innovation associated with the green revolution, 1968-1982. We establish that land prices capitalize expected future technologies and use the spatial and temporal variation in land prices to determine how household schooling decisions by land status are influenced by expected technological change. We find that higher expected future technology and increases in the number of schools, for given current productivity, raise schooling in landed households. However, although increased school availability also increases schooling in landless households we find that, consistent with the operation of a child labor market, high rates of expected technology for given school availability and for given current agricultural productivity tends to substantially decrease schooling investment in landless households.
Use of Cyclophosphamide in a Child With Fulminant Acute Disseminated Encephalomyelitis

Acute disseminated encephalomyelitis is an immune-mediated inflammatory demyelinating disorder of the central nervous system. The first-line treatment is usually high-dose intravenous methylprednisolone. Intravenous immunoglobulin and plasmapheresis have also shown to be beneficial. Immunosuppressive agents like cyclophosphamide have been used in adults with fulminant acute disseminated encephalomyelitis. We report a case of a 3-year-old boy with fulminant acute disseminated encephalomyelitis. Minimal improvement was seen with high-dose intravenous methylprednisolone, intravenous immunoglobulin, and plasmapheresis. Based on the reports of cyclophosphamide being used successfully to treat adult patients with fulminant acute disseminated encephalomyelitis, we used it in our patient who then showed dramatic and quick improvement. We suggest that if conventional treatment fails, cyclophosphamide could be tried in pediatric patients with fulminant acute disseminated encephalomyelitis.
Trending topic prediction by optimizing K-nearest neighbor algorithm

Quick and accurate decision-making has currently been a modern governmental characteristic, since the development of information and communication technologies also grow very rapidly. One way to support the quick and accurate decision-making is predicting the trending topic. The research aimed at assisting the government of Makassar City to predict the trending topic which would happen by analyzing the historical stack in the data mining. The method used was K-Nearest Neighbor (KNN), in which prediction on the trending topic was determined based on the membership distance of a class. The research was conducted based on the news and conversation taken from the online and social media related to Makassar City Government with 393.667 raw data, in which the preprocessing was then carried out to determine the trending and non-trending conversations, producing 2007 trained and tested data. The system performance analysis technique applied was confusion matrix with calculation of percentages of the accuracy, precision, and recall. The result showed that using K-Nearest Neighbor (KNN), the accuracy of 81,13% is obtained.
- LOOP UWB FILTER WITH NOTCHED

A bandpass filter (BPF) is presented for ultra-wideband (UWB) applications with a notched band to reject the unwanted signals from the wireless local area network (WLAN) systems. The proposed UWB BPF consists of two pairs of open-loop resonators on the top layer and one coupled resonator on the bottom layer. The rejection band is introduced by adding an asymmetric openloop resonator to two outer arms of open-loop resonators. The bandpass filter is designed to be operated within full bandwidth of 3.1 to 10.6 GHz and to eliminate the WLAN signals of 5.8 GHz. The suppression at 5.8 GHz is larger than 15 dB. The proposed configuration is proved to be both simple and compact.
Seasonal trends in hypertension in Poland: evidence from Google search engine query data.

BACKGROUND Various conditions, including arterial hypertension, exhibit seasonal trends in their occurrence and magnitude. Those trends correspond to an interest exhibited in the number of Internet searches for the specific conditions per month. AIM The aim of the study was to show seasonal trends in the hypertension prevalence in Poland relate to the data from the Google Trends tool. METHODS Internet search engine query data were retrieved from Google Trends from January 2008 to November 2017. Data were calculated as a monthly normalised search volume from the nine-year period. Data was presented for specific geographic regions, including Poland, the United States of America, Australia, and worldwide for the following search terms: "arterial hypertension (pol. nadciśnienie tętnicze)", "hypertension (pol. nadciśnienie)" and "hypertension medical condition". Seasonal effects were calculated using regression models and presented graphically. RESULTS In Poland the search volume is the highest between November and May, while patients exhibit the least interest in arterial hypertension during summer holidays (p < 0.05). Seasonal variations are comparable in the United States of America representing a Northern hemisphere country, while in Australia (Southern hemisphere) they exhibit a contrary trend. CONCLUSIONS In conclusion, arterial hypertension is more likely to occur during winter months, which correlates with increased interest in the search phrase "hypertension" in Google.
Transcriptional Dynamics Elicited by a Short Pulse of Notch Activation Involves Feed-Forward Regulation by E(spl)/Hes Genes

Dynamic activity of signaling pathways, such as Notch, is vital to achieve correct development and homeostasis. However, most studies assess output many hours or days after initiation of signaling, once the outcome has been consolidated. Here we analyze genome-wide changes in transcript levels, binding of the Notch pathway transcription factor, CSL [Suppressor of Hairless, Su(H), in Drosophila], and RNA Polymerase II (Pol II) immediately following a short pulse of Notch stimulation. A total of 154 genes showed significant differential expression (DE) over time, and their expression profiles stratified into 14 clusters based on the timing, magnitude, and direction of DE. E(spl) genes were the most rapidly upregulated, with Su(H), Pol II, and transcript levels increasing within 5–10 minutes. Other genes had a more delayed response, the timing of which was largely unaffected by more prolonged Notch activation. Neither Su(H) binding nor poised Pol II could fully explain the differences between profiles. Instead, our data indicate that regulatory interactions, driven by the early-responding E(spl)bHLH genes, are required. Proposed cross-regulatory relationships were validated in vivo and in cell culture, supporting the view that feed-forward repression by E(spl)bHLH/Hes shapes the response of late-responding genes. Based on these data, we propose a model in which Hes genes are responsible for co-ordinating the Notch response of a wide spectrum of other targets, explaining the critical functions these key regulators play in many developmental and disease contexts.
Effects of aging on fat deposition and meat quality in Sheldrake duck

ABSTRACT Sheldrake is a duck breed widely used for its meat and eggs. In this study, the quantities of abdominal fat, sebum, intramuscular fat and liver fat, meat quality (pH, cooking loss, drip loss, and shear force), and expression and activity of several enzymes at different ages were determined. The results showed that the fat content increased (P < 0.05) during the aging process (90 d, 180 d, 270 d, and 360 d). Fatty acid synthase (FAS) and malic enzyme (ME) were chosen to represent the activity of lipid biosynthesis in Sheldrake ducks. The quantitative real‐time PCR and enzymic activity data showed that the expression of both FAS and ME were generally up‐regulated along with aging. Based on these results, the individual ducks were selected at 180 d and 360 d for analyzing the changes of serum lipid levels and related enzymic activities in liver. The contents of triglycerides (TG), total cholesterol (TCH), high‐density lipoprotein (HDL), and low‐density lipoprotein (LDL) in serum were found not significantly different (P > 0.05). However, we thought that the variation of TG/HDL (P < 0.05) might explain the increased fat deposition. Moreover, the activities of lipoprotein lipase (LPL) and hepatic lipase (HL) were both detected significantly up‐regulated at 360 d (P < 0.05). The meat quality results of breast muscles indicated that pH, cooking loss, drip loss, and shear force values could all be affected by aging. Considering these results, we concluded that the best quality of Sheldrake duck meat occurs between 180 d and 270 d. These results might provide useful information for Sheldrake cultivation and research on lipid metabolism.
Parental health behaviour predictors of childhood and adolescent dietary trajectories

Abstract Objective To determine which parental health behaviours early in childhood most strongly predict whole-of-childhood dietary trajectories. Design Population-based Longitudinal Study of Australian Children (LSAC, waves 1–6; 2004–2014). Exposures were parents’ fruit/vegetable consumption, alcohol, smoking and physical activity at child age 0–1 years (B Cohort) or 4–5 years (K Cohort). Outcomes, from repeated biennial short diet diaries, were group-based trajectories of (i) dietary scores and empirically derived patterns of (ii) healthful and (iii) unhealthful foods consumed, spanning ages 2–3 to 10–11 years (B Cohort) and 4–5 to 14–15 years (K Cohort). We investigated associations of baseline parental health behaviours with child dietary trajectories using multinomial logistic regression. Setting Australian homes. Subjects Of children, 4443 (87·0 %) from the B Cohort and 4620 (92·7 %) from the K Cohort were included in all trajectories. Multivariable analyses included 2719 to 2905 children and both parents. Results Children whose primary caregiver reported the lowest fruit/vegetable consumption had markedly higher odds of belonging to the least healthy score and pattern trajectories (K Cohort: OR=8·7, 95 % CI 5·0, 15·1 and OR=8·4, 95 % CI 4·8, 14·7, respectively); associations were weaker (K Cohort: OR=2·3, 95 % CI 1·0, 5·2) for the unhealthiest pattern trajectory. Secondary caregiver fruit/vegetable associations were smaller and inconsistent. Parental alcohol, smoking and physical activity were not predictive in multivariable analyses. Results were largely replicated for the B Cohort. Conclusions Low primary caregiver fruit/vegetable consumption increased nearly ninefold the odds of children being in the lowest intake of healthy, but only weakly predicted unhealthy, food trajectories. Healthy and unhealthy food intake may have different determinants.
Local and Global Feature Learning for Blind Quality Evaluation of Screen Content and Natural Scene Images

The blind quality evaluation of screen content images (SCIs) and natural scene images (NSIs) has become an important, yet very challenging issue. In this paper, we present an effective blind quality evaluation technique for SCIs and NSIs based on a dictionary of learned local and global quality features. First, a local dictionary is constructed using local normalized image patches and conventional $K$ -means clustering. With this local dictionary, the learned local quality features can be obtained using a locality-constrained linear coding with max pooling. To extract the learned global quality features, the histogram representations of binary patterns are concatenated to form a global dictionary. The collaborative representation algorithm is used to efficiently code the learned global quality features of the distorted images using this dictionary. Finally, kernel-based support vector regression is used to integrate these features into an overall quality score. Extensive experiments involving the proposed evaluation technique demonstrate that in comparison with most relevant metrics, the proposed blind metric yields significantly higher consistency in line with subjective fidelity ratings.
ρ-hot Lexicon Embedding-based Two-level LSTM for Sentiment Analysis

Sentiment analysis is a key component in various text mining applications. Numerous sentiment classification techniques, including conventional and deep learning-based methods, have been proposed in the literature. In most existing methods, a high-quality training set is assumed to be given. Nevertheless, constructing a high-quality training set that consists of highly accurate labels is challenging in real applications. This difficulty stems from the fact that text samples usually contain complex sentiment representations, and their annotation is subjective. We address this challenge in this study by leveraging a new labeling strategy and utilizing a two-level long short-term memory network to construct a sentiment classifier. Lexical cues are useful for sentiment analysis, and they have been utilized in conventional studies. For example, polar and privative words play important roles in sentiment analysis. A new encoding strategy, that is, $\rho$-hot encoding, is proposed to alleviate the drawbacks of one-hot encoding and thus effectively incorporate useful lexical cues. We compile three Chinese data sets on the basis of our label strategy and proposed methodology. Experiments on the three data sets demonstrate that the proposed method outperforms state-of-the-art algorithms.
Temperature-Sensitive Gold Nanoparticle-Coated Pluronic-PLL Nanoparticles for Drug Delivery and Chemo-Photothermal Therapy

Gold nanoparticle-coated Pluronic-b-poly(L-lysine) nanoparticles (Pluronic-PLL@Au NPs) were synthesized via an easy one-step method and employed as carriers for the delivery of paclitaxel (PTX) in chemo-photothermal therapy, in which Pluronic-PLL acts as the reductant for the formation of AuNPs without the need for an additional reducing agent. Methods: The deposition of AuNPs on the surface of Pluronic-PLL micelles and the thermal response of the system were followed via ultraviolet-visible spectroscopy and dynamic light scattering. Calcein-AM and MTT assays were used to study the cell viability of MDA-MB-231 cells treated with PTX-loaded Pluronic-PLL@Au NPs, and we then irradiated the cells with NIR light. Results: An obvious temperature response was observed for the Pluronic-PLL@Au NPs. Blood compatibility and in vitro cytotoxicity assays confirmed that the Pluronic-PLL@Au NPs have excellent biocompatibility. Compared to Taxol, the PTX-loaded Pluronic-PLL@Au NPs exhibited higher cytotoxicity in MDA-MB-231 cells. All of these results and confocal laser scanning microscopy analysis results suggest that Pluronic-PLL@Au NPs greatly enhance the cellular uptake efficiency of the drug. Conclusion: As confirmed by in vitro and in vivo studies, the combination of chemotherapy and photothermal therapy can cause more damage than chemo- or photothermal therapy did alone, demonstrating the synergistic effect of chemo-photothermal treatment. Thus, the as-prepared Pluronic-PLL@Au NPs are promising for chemo-photothermal therapy.
Predicting Visual Consciousness Electrophysiologically from Intermittent Binocular Rivalry

Purpose We sought brain activity that predicts visual consciousness. Methods We used electroencephalography (EEG) to measure brain activity to a 1000-ms display of sine-wave gratings, oriented vertically in one eye and horizontally in the other. This display yields binocular rivalry: irregular alternations in visual consciousness between the images viewed by the eyes. We replaced both gratings with 200 ms of darkness, the gap, before showing a second display of the same rival gratings for another 1000 ms. We followed this by a 1000-ms mask then a 2000-ms inter-trial interval (ITI). Eleven participants pressed keys after the second display in numerous trials to say whether the orientation of the visible grating changed from before to after the gap or not. Each participant also responded to numerous non-rivalry trials in which the gratings had identical orientations for the two eyes and for which the orientation of both either changed physically after the gap or did not. Results We found that greater activity from lateral occipital-parietal-temporal areas about 180 ms after initial onset of rival stimuli predicted a change in visual consciousness more than 1000 ms later, on re-presentation of the rival stimuli. We also found that less activity from parietal, central, and frontal electrodes about 400 ms after initial onset of rival stimuli predicted a change in visual consciousness about 800 ms later, on re-presentation of the rival stimuli. There was no such predictive activity when the change in visual consciousness occurred because the stimuli changed physically. Conclusion We found early EEG activity that predicted later visual consciousness. Predictive activity 180 ms after onset of the first display may reflect adaption of the neurons mediating visual consciousness in our displays. Predictive activity 400 ms after onset of the first display may reflect a less-reliable brain state mediating visual consciousness.
Melatonin Promotes Cheliped Regeneration, Digestive Enzyme Function, and Immunity Following Autotomy in the Chinese Mitten Crab, Eriocheir sinensis

In the pond culture of juvenile Eriocheir sinensis, a high limb-impairment rate seriously affects the culture success. Therefore, it is particularly important to artificially promote limb regeneration. This study evaluated the effects of melatonin on cheliped regeneration, digestive ability, and immunity, as well as its relationship with the eyestalk. It was found that the injection of melatonin significantly increased the limb regeneration rate compared with the saline group (P < 0.05). The qRT-PCR results of growth-related genes showed that the level of EcR-mRNA (ecdysteroid receptor) and Chi-mRNA (chitinase) expression was significantly increased following the melatonin injection, while the expression of MIH-mRNA (molt-inhibiting hormone) was significantly decreased (P < 0.05). Melatonin significantly increased lipase activity (P < 0.05). We observed that the survival rates of limb-impaired and unilateral eyestalk-ablated crabs were substantially improved following melatonin treatment, whereas the survival of the unilateral eyestalk-ablated crabs was significantly decreased compared with the control group (P < 0.05). Furthermore, the results of serum immune and antioxidant capacity revealed that melatonin significantly increased the total hemocyte counts (THC), hemocyanin content, total antioxidant capacity (T-AOC), acid phosphatase (ACP), and glutathione peroxidase activity (GSH-Px), whereas the immune-related parameters were significantly decreased in eyestalk-ablated crabs (P < 0.05). Therefore, these findings indicate that melatonin exerts a protective effect on organism injury, which could promote limb regeneration by up-regulating the expression of growth-related genes, improve digestive enzyme activity, and strengthen the immune response, particularly antioxidant capacity.
Compute-and-forward with relay selection: A cooperative game

Motivated by the cooperative game theory, we propose an efficient physical layer network coding technique for compute-and-forward (C&F) relaying systems, which jointly optimizes the sum and the minimum transmission rate, while minimizing the total transmitting power. Specifically, we show that relay selection in C&F networks leads to an increase of both rates. We also propose an algorithmic approach for the rates' further optimization and we illustrate that its implementation can offer the same or even greater gain than adding an extra relay. Furthermore, the tradeoff between the minimum and the sum rate is explained by utilizing the concept of Pareto frontier. Simulations and numerical results show that a combination of relay selection and the proposed algorithms offers a considerable increase in the sum rate for the same transmitting power, without reducing the system's Quality of Service.
Spatial organization of the pigeon tectorotundal pathway: An interdigitating topographic arrangement

The retinotectofugal system is the main visual pathway projecting upon the telencephalon in birds and many other nonmammalian vertebrates. The ascending tectal projection arises exclusively from cells located in layer 13 of the optic tectum and is directed bilaterally toward the thalamic nucleus rotundus. Although previous studies provided evidence that different types of tectal layer 13 cells project to different subdivisions in Rt, apparently without maintaining a retinotopic organization, the detailed spatial organization of this projection remains obscure. We reexamined the pigeon tectorotundal projection using conventional tracing techniques plus a new method devised to perform small deep‐brain microinjections of crystalline tracers. We found that discrete injections involving restricted zones within one subdivision retrogradely label a small fraction of layer 13 cells that are distributed throughout the layer, covering most of the tectal representation of the contralateral visual field. Double‐tracer injections in one subdivision label distinct but intermingled sets of layer 13 neurons. These results, together with the tracing of tectal axonal terminal fields in the rotundus, lead us to propose a novel “interdigitating” topographic arrangement for the tectorotundal projection, in which intermingled sets of layer 13 cells, presumably of the same particular class and distributed in an organized fashion throughout the surface of the tectum, terminate in separate regions within one subdivision. This spatial organization has significant consequences for the understanding of the physiological and functional properties of the tectofugal pathway in birds. J. Comp.

Modulus Mapping of Rubbers Using Micro- and Nano-Indentation Techniques

Abstract Modulus measurements are among the most useful properties available for monitoring the cure and aging of rubbers. Historically, such measurements were done on macroscopic samples, but over the past 15 years, several penetration techniques have been and are being developed that allow quantitative estimates of modulus to be made with lateral resolutions of 100 μm or better. This review summarizes these developments and the types of unique information that can be generated on rubbery materials. A large part of the review focuses on the types of results available from a modulus profiling apparatus that has been used to study rubbers for the past 15 years. This instrument allows estimates to be made of the inverse tensile compliance (closely related to Young's tensile modulus) with a lateral resolution of around 50 to 100 μm. Several recently developed alternative methods for achieving similar spatial resolution are also described. Finally, a brief review is given of the recent attempts to measure qua.
