Application of improved ant colony algorithm in food delivery system

With the rapid development of China's economy and the improvement of the pace of life, takeaway has become a part of young people's life. How to effectively deliver takeaway delivery personnel in a limited time is an urgent problem to be solved in the current delivery system. At present, there are some problems in the system, such as path redundancy and large sample size, which affect the efficiency and speed of the food distribution system. In this paper, the original ant colony algorithm is improved by using pheromones released by ants and path-finding methods. In order to reduce the redundancy of path selection, improve the computational efficiency and find the optimal balanced path, ant colony optimization algorithm is considered to select the distribution path. Experimental results show that this algorithm can find the global optimal path more accurately than the traditional ant colony algorithm.
Innovation through Emergence of Technology Communities: Some Management Lessons

Networks play a key role in developing next generation innovations. Technology led innovations are led by technology developers and communities. There is an evidence of success of innovations in technology development through networking with technology communities. Some of these are formal networks and some of these are informal networks. This paper explores at some of the successful developments in the technology domains such as development of Android applications and I-phone applications. Each of these interventions involved collaborations between academic communities, corporate firms as well as independent technical professionals. The success of Apple and Android communities opens up many new research questions as both the organizations have followed a very different approach in developing new technologies. Android which is developed by Google has followed a different approach as compared to development of Apple applications. The paper would throw insights into these approaches. Some of the technology communities had a more open approach and some of the communities have a more closed approach. This paper documents the differences in approaches of development of these communities. The paper is a qualitative study which provides an insight into the differences in approach of development of select technology communities. The paper also draws leadership lessons and factors which contribute to the success of such initiatives. The paper assesses the challenges that these firms faced in developing such communities.
Structured Models for Action Recognition in Real-word Videos

This dissertation introduces novel models to recognize broad action categories --- like "opening a door" and "running" --- in real-world video data such as movies and internet videos. In particular, we investigate how an action can be decomposed, what is its discriminative structure, and how to use this information to accurately represent video content. The main challenge we address lies in how to build models of actions that are simultaneously information-rich --- in order to correctly differentiate between different action categories --- and robust to the large variations in actors, actions, and videos present in real-world data. We design three robust models capturing both the content of and the relations between action parts. Our approach consists in structuring collections of robust local features --- such as spatio-temporal interest points and short-term point trajectories. We also propose efficient kernels to compare our structured action representations. Even if they share the same principles, our methods differ in terms of the type of problem they address and the structure information they rely on. We, first, propose to model a simple action as a sequence of meaningful atomic temporal parts. We show how to learn a flexible model of the temporal structure and how to use it for the problem of action localization in long unsegmented videos. Extending our ideas to the spatio-temporal structure of more complex activities, we, then, describe a large-scale unsupervised learning algorithm used to hierarchically decompose the motion content of videos. We leverage the resulting tree-structured decompositions to build hierarchical action models and provide an action kernel between unordered binary trees of arbitrary sizes. Instead of structuring action models, we, finally, explore another route: directly comparing models of the structure. We view short-duration actions as high-dimensional time-series and investigate how an action's temporal dynamics can complement the state-of-the-art unstructured models for action classification. We propose an efficient kernel to compare the temporal dependencies between two actions and show that it provides useful complementary information to the traditional bag-of-features approach. In all three cases, we conducted thorough experiments on some of the most challenging benchmarks used by the action recognition community. We show that each of our methods significantly outperforms the related state of the art, thus highlighting the importance of structure information for accurate and robust action recognition in real-world videos.
Propulsion of an artificial nanoswimmer: a comprehensive review

Locomotion at micro and nano scales is a challenge and has drawn attention for over six decades. Inspired by nature, studies have mimicked nanoswimming organisms, which use rotating or beating flagella for locomotion. This mode of propulsion, also known as flagellar propulsion, has been explored extensively in the literature. However, chemical and magnetic methods have gained interest in the last decade owing to advantages including high thrust force and wireless control. The review summarizes chronologically the various propulsion mechanisms for moving a nanoswimmer using chemical fuel, magnetic fields, ultrasonic pulses and thrust force generated by bacteria in the presence of external stimuli including laser light, and thermal and chemical gradients.

A Panel Data Analysis of Foreign Trade Determinants of Nepal: Gravity Model Approach

This study aims to identify the trade (export, import and trade balance) determinants of Nepal using extended gravity model and recommend specific trade policy to promote foreign trade. The gravity model of international trade takes notion from Newtonian physical science that the gravitational force between any two objects is proportional to the product of their masses and inversely proportional to distance; similarly, the trade between any two countries is proportional to the product of their GDPs and inversely proportional to distance. Empirical results based on panel data set containing 21 major trade partner countries for 6 years found that export and import of Nepal is explained by real GDP of trade partner countries. Increase in real GDP of trade partner countries increases both export and import; however, export increases at higher rate than import. The trade deficit of Nepal increases if real GDP of trade partner country increases, even though export is increasing at higher rate than import. This is because Nepal is importing more than exporting to those countries in absolute terms. Nepal exports more to SAFTA countries than non-SAFTA and imports less from the OECD countries than non-OECD. As per basic idea of gravity model, distance to trade partner countries is highly significant implying higher the distance, lower the trade. The country specific fixed effect analysis shows that time invariant factors are also significant to determine the trade balance of Nepal.
Genetic Variability, Heritability and Genetic Advance of Kabuli Chickpea (Cicer arietinum L.) for Agronomic Traits at Central Ethiopia Genetic Variability, Heritability and Genetic Advance of Kabuli Chickpea (Cicer arietinum L.) for Agronomic Traits at Central Ethiopia

The present study was carried out to assess the extent of genetic variability among yield and yield related traits in selected kabuli chickpea genotypes. Forty-nine kabuli chickpea genotypes were studied for thirteen traits at Debre Zeit and Akaki using 7x7 simple lattice design in 2018 cropping season. Combined analysis of variance revealed that there was a significant difference among genotypes for all traits studied, indicating the presence of considerable amount of variability among genotypes. High Phenotypic coefficients of variation and moderate genotypic coefficients of variation value were shown for number of pods per plant and number of seeds per plant, respectively, indicating the possibility of genetic improvement in selection of these traits. High broad sense heritability coupled with high genetic advance were obtained for hundred-seed weight (91.88 and 23.81), number of pods per plant (68.07 and 28.13), number of secondary branches (80.92 and 27.80), number of seeds per plant (67.86 and 31.840), grain yield (62.33 and 24.42) and harvest index (75.70 and 28.17), respectively. This indicates that these characters could be improved easily through selection.
Speech to the electors of Bristol

Within Political Theory, this speech presents Edmund Burke's conception of political representation, that is, the relations between elected representatives and their electors. Burke rejected the mandate of the imperative type in which representatives heed only local demands and proposals coming from electors, which they then reproduce within parliament. This would make them more akin to spokespersons with the right to vote than to politicians seeking the common good through rational debate with other politicians. In contrast to that model of representation, Burke proposes what today we refer to as "representative mandate" in which representatives are acquainted with local demands yet, without neglecting them, seek to join other representatives in composing general policies. The underlying rationale is that representatives together make up a parliament meant to serve the nation as a whole rather than one locale or another; thus, they should formulate policies that take the whole country into account.

Clinical research of extensive regional field radiotherapy concurrent with chemotherapy for locally advanced esophageal cancer

Objective To evaluate the efficacy and side effects of extensive regional field radiotherapy concurrent with chemotherapy for locally advanced esophageal cancer.Methods Of the 101 patients with locally advanced esophageal cancer patients,44 patients were treated by involved field radiotherapy alone,29 patients treated by involved field radiotherapy combined with chemotherapy,and 28 patients received extensive regional field radiotherapy combined with chemotherapy,the total dose of radiotherapy was 60 Gy.The clinical target volume (CTV) of involved field included the gross tumor volume (GTV) plus a 0.8 cm lateral margin,the tumor plus a nominal 3-5 cm cephalad and caudal margin.Extensive regional field radiotherapy was delivered in two steps:the CTV included the CTV of the involved field plus elective nodal region in the first step;in the second step,the CTV definition was same with the CTV of the involved field.Synchronous chemotherapy regimens included TP and NP.Results 90.1％patients completed planned radiotherapy,all patients in the concurrent chemotherapy groups completed at least one cycle of chemotherapy.The follow-up rate was 99％. Twenty-four and 42 patients completed followed-up more than 24 months in the radiotherapy alone and concurrent chemoradiotherapy group,respectively.The median survival time of the involved field radiotherapy group,involved field chemoradiotherapy group and extensive regional field chemoradiotherapy group was 13,21 and 19 months,respectively;the 2-year overall survival (OS) rate was 15％,48％ and 46％,respectively for the three groups.The 2-year OS rate was improved significantly in the chemoradiotherapy group (x2 =6.83,P =0.033). Compared with radiotherapy alone group,the incidence of grade three or four bone marrow suppression was higher in the concurrent chemoradiotherapy group (53％: 0 ％,x2 =32.94,P =0.000),the remaining adverse events (acute radiation pneumonitis,acute radiation esophagitis,esophageal fibrosis,late radiation lung injury) had no significant intergroup differences (x2 =5.56,6.70,2.39,0.42,P =0.235,0.349,0.881,0.981). Conclusions Compared with radiotherapy alone,concurrent chemoradiotherapy can improve the survival rate for locally advanced esophageal cancer.The side effects of the extensive regional field radiotherapy combined with chemotherapy is well tolerated.But the efficacy of the extensive regional field radiotherapy combined with chemotherapy needs further research.

Near Optimal Indoor Localization With Coherent Array Reconciliation Tomography

Our increased reliance on localization devices such as GPS navigation has led to an increased demand for localization solutions in all environments, including indoors. Indoor localization has received considerable attention in the last several years for a number of application areas including first responder localization to targeted advertising and social networking. The difficult multipath encountered indoors degrades the performance of RF based localization solutions and so far no optimal solution has been published. This dissertation presents an algorithm called Coherent Array Reconciliation Tomography (CART), which is a Direct Positioning Algorithm (DPA) that incorporates signal fusion to perform a simultaneous leading edge and position estimate for a superior localization solution in a high multipath environment. The CART algorithm produces position estimates that are near optimal in the sense that they achieve nearly the best theoretical accuracy possible using an Impulse Radio (IR) Ultra-Wideband (UWB) waveform. Several existing algorithms are compared to CART including a traditional two step Leading Edge Detection (LED) algorithm, Singular value Array Reconciliation Tomography (SART), and Transactional Array Reconciliation Tomography (TART) by simulation and experimentation. As shown under heavy simulated multipath conditions, where traditional LED produces a limited solution and the SART and TART algorithms fail, the CART algorithm produces a near statistically optimal solution. Finally, the CART algorithm was also successfully demonstrated experimentally in a laboratory environment by application to the fire fighter homing device that has been a part of the ongoing research at Worcester Polytechnic Institute (WPI).

Influence of the Glucocorticoid Receptor on microRNA Profile in Triple-Negative Breast Cancer

Breast cancer (BC) is the most prevalent type of cancer in women and leads to high mortality rates (World Health Organization 2017). In particular, triple–negative breast cancer (TNBC) is known as a heterogeneous and very aggressive BC subtype, characterized by its negative profile of progesterone receptor (PR), estrogen receptor (ER), and human epidermal growth factor receptor 2 (HER2). These features are the main reason why there is still no effective treatment available. Glucocorticoids (GCs), which are usually used as coadjuvants in the treatment of several malignancies, are a group of corticosteroid hormones that act by binding to glucocorticoid receptors (GRs). GRs are crucial transcriptional factors involved in gene regulation. However, high GR expression in TNBC was recently linked to poorer survival rates in TNBC patients (Chen et al. 2015). Furthermore, it is known that GRs are not only capable of influencing the expression of protein coding genes but also modulate microRNA (miRNAs) expression, which are small noncoding elements that likewise regulate gene expression. The initiation and progression of BC are associated with miRNA dysregulation, which can either act as oncogenic or tumor suppressor factors (Andorfer et al. 2011). To broaden the knowledge in this research field, the project aimed to identify cellular miRNAs regulated by GR in TNBC. Experimental procedures included: cell culture of three TNBC cell lines in three different conditions (endogenous GR expression; transfected with a NR3C1 plasmid, encoding the GR; transfected with silencing RNA (siRNA), silencing endogenous NR3C1 gene expression); isolation of RNA, including quality control, and quantification; preparation of a library for Next–Generation Sequencing (NGS), and bioinformatics analysis of NGS data. Seven miRNAs were found to be significantly regulated by GR in TNBC, of which some corroborate previous findings of associations with activation of oncogenic pathways. Our results further indicate that GR–regulated miRNA expression may be TNBC subclass specific. In light of our findings, miRNAs may be effective biomarkers for the diagnosis and prognosis of TNBC. Further research is necessary to describe their function and to assess in which TNBC’s subclass pathways they may be involved, so that TNBC patients may eventually have access to better predicted outcomes and treatment.

Partitioning net ecosystem carbon exchange with isotopic fluxes of CO2

Because biological and physical processes alter the stable isotopic composition of atmospheric CO2, variations in isotopic content can be used to investigate those processes. Isotopic flux measurements of 13CO2 above terrestrial ecosystems can potentially be used to separate net ecosystem CO2 exchange (NEE) into its component fluxes, net photosynthetic assimilation (FA) and ecosystem respiration (FR). In this paper theory is developed to partition measured NEE into FA and FR, using measurements of fluxes of CO2 and 13CO2, and isotopic composition of respired CO2 and forest air. The theory is then applied to fluxes measured (or estimated, for 13CO2) in a temperate deciduous forest in eastern Tennessee (Walker Branch Watershed). It appears that there is indeed enough additional information in 13CO2 fluxes to partition NEE into its photosynthetic and respiratory components. Diurnal patterns in FA and FR were obtained, which are consistent in magnitude and shape with patterns obtained from NEE measurements and an exponential regression between night‐time NEE and temperature (a standard technique which provides alternate estimates of FR and FA). The light response curve for photosynthesis (FA vs. PAR) was weakly nonlinear, indicating potential for saturation at high light intensities. Assimilation‐weighted discrimination against 13CO2 for this forest during July 1999 was 16.8–17.1‰, depending on canopy conductance. The greatest uncertainties in this approach lie in the evaluation of canopy conductance and its effect on whole‐canopy photosynthetic discrimination, and thus the indirect methods used to estimate isotopic fluxes. Direct eddy covariance measurements of 13CO2 flux are needed to assess the validity of the assumptions used and provide defensible isotope‐based estimates of the component fluxes of net ecosystem exchange.
