    The emergence of the phenomenon of shifting cultural values contained in the motif by economic function raises concerns about the preservation of classic Indonesian batik motifs, especially the classic motifs of Tuban. Therefore, it takes a media design information in the form of book illustration to raise cultural values such as meaning, philosophy and myths contained in the classical batik Tuban. This design is done with the approach of observation, interviews and existing studies using the keyword viewpoint literature review results, namely the aesthetic, social, cultural, self-image and cultural products. By using descriptive-qualitative method of analysis that is supported by indicators STP and USP (Unique Selling Proposition) obtained "Covert charm" as a design concept and “Canting Batik Tuban" as the title of a book with manual drawing illustrations as main illustration. To determine the effectiveness, feasibility and suitability of the work used the test results of the questionnaire design through Likert scale. From the results of the correlation analysis of the design testing, it was found that all of the results of the questionnaire statements have a significant correlation so as to fulfill the purpose of the book value of the loading statement, 242- , 362 and the mean between 4.27 to 4.62

    We combine confocal imaging, microfluidics and image analysis to record 3D-images of cells in flow. This enables us to recover the full 3D representation of several hundred living cells per minute. Whereas 3D confocal imaging has thus far been limited to steady specimen, we overcome this restriction and present a method to access the 3D shape of moving objects. The key of our principle is a tilted arrangement of the micro-channel with respect to the focal plane of the microscope. This forces cells to traverse the focal plane in an inclined manner. As a consequence, individual layers of passing cells are recorded which can then be assembled to obtain the volumetric representation. The full 3D information allows for a detailed comparisons with theoretical and numerical predictions unfeasible with e.g.\ 2D imaging. Our technique is exemplified by studying flowing red blood cells in a micro-channel reflecting the conditions prevailing in the microvasculature. We observe two very different types of shapes: `croissants' and `slippers'. Additionally, we perform 3D numerical simulations of our experiment to confirm the observations. Since 3D confocal imaging of cells in flow has not yet been realized, we see high potential in the field of flow cytometry where cell classification thus far mostly relies on 1D scattering and fluorescence signals

    Breast cancer is the second leading cause of disease death in women, after lung and bronchus cancer. According to measurements, mammography misses breast cancer in 10% to 15% of cases for women aged 50 to 69 years. In the current study, we used the Wisconsin breast cancer dataset to develop a two-stage model for breast cancer diagnosis. The main goal of this study effort is to effectively carry out feature selection and classification tasks. Gradient Boosting Decision Tree-based Mayfly Optimisation (GBDTMO), an innovative and efficient breast cancer diagnostic machine learning system, is provided. In the second stage, we employ a Mayfly search to determine which subset of traits is the best. Two more well-known datasets on breast cancer, the ICCR and the Cancer Corpus, were also compared for classification accuracy. The accuracy of the suggested GBDTMO model was higher than that of the existing GBDT and Practical Federated Gradient Boosting Decision Tree (PFGBDT), which had accuracy values of 93.25% and 94.25%, respectively. Similarly, the recall, F-measure, and ROC area values were 98.52%, 97.52%, and 96.32%, respectively. Furthermore, it demonstrated a lower RMSE of 0.98 than the existing GBDT and PFGBDT

    The purposes of this research is to analyze the beneficial of Bank Perkreditan Rakyat (BPR) Buana Agribisnis Saribudolok for expanding peasant's enterprise on subdistrict Silimakuta Regency of Simalungun, by the average income of the peasant. The independent variablesused in this research was the capital credit issued by BPR Buana Agribisnis Saribudolok. The data used in this study obtained from 78 peasants which the clientele of the institution, by simple random sampling. The analysis method used in this study is Descriptive Analysis by Simple Linear Regression, test of godness of fit and test penyimpangan asumsi klasik on SPSS 16.0 programme. The result shows that capital credit issued by BPR significantly affect the expanding peasant's enterprise on the increasing average income

    From quantum pulse gate to quantum pulse shaper -- enigneered frequency conversion in nonlinear optical waveguides

    Full text link
    Full control over the spatio-temporal structure of quantum states of light is an important goal in quantum optics, to generate for instance single-mode quantum pulses or to encode information on multiple modes, enhancing channel capacities. Quantum light pulses feature an inherent, rich spectral broadband-mode structure. In recent years, exploring the use of integrated optics as well as source-engineering has led to a deep understanding of the pulse-mode structure of guided quantum states of light. In addition, several groups have started to investigate the manipulation of quantum states by means of single-photon frequency conversion. In this paper we explore new routes towards complete control of the inherent pulse-modes of ultrafast pulsed quantum states by employing specifically designed nonlinear waveguides with adapted dispersion properties. Starting from our recently proposed quantum pulse gate (QPG) we further generalize the concept of spatio-spectral engineering for arbitrary \chitwo-based quantum processes. We analyse the sum-frequency generation based QPG and introduce the difference-frequency generation based quantum pulse shaper (QPS). Together, these versatile and robust integrated optics devices allow for arbitrary manipulations of the pulse-mode structure of ultrafast pulsed quantum states. The QPG can be utilized to select an arbitrary pulse mode from a multimode input state, whereas the QPS enables the generation of specific pulse modes from an input wavepacket with Gaussian-shaped spectrum.Comment: 21 pages, 9 figure

    Postsynthetic Functionalization of DNA-Nanocomposites with Proteins Yields Bioinstructive Matrices for Cell Culture Applications

    Get PDF
    We report on the directed postsynthetic functionalization of soft DNA nanocomposite materials with proteins. Using the example of the functionalization of silica nanoparticle‐modified DNA polymer materials with agonists or antagonists of the epidermal growth factor receptor EGFR cell membrane receptor, we demonstrate that hierarchically structured interfaces to living cells can be established. Owing to the modular design principle, even complex DNA nanostructures can be integrated into the materials, thereby enabling the high‐precision arrangement of ligands on the lower nanometer length scale. We believe that such complex biohybrid material systems can be used for new applications in biotechnology
