Li-Fi stands for Light-Fidelity. This technology is very new and was proposed by the German physicist Harald Haas in 2011. Light based communication system is the backbone of the future of the communication system. Li-Fi is a wireless technology that uses light emitting diodes (LEDs) for transmission of data. The development of the wireless communication leads to advance research in LiFi technology. The term Li-Fi states to visible light communication (VLC) technology that uses as medium to deliver high-speed communication in a fashion similar to Wi-Fi. Li-Fi comprises a wide range of frequencies and wavelengths, from the Infrared through visible and down to the Ultraviolet spectrum. The immense use of Li-Fi may solve some bottleneck of data transmission in Wi-Fi technology. With the innovation in technology and the number of users, the existing radio-wave spectrum fails to accommodate this need. To resolve the issues of scalability, availability and security, we have come up with the concept of transmitting data wirelessly through light using visible light communication (VLC) technology. This paper objective is to study and describe the LiFi technology. The improvement of the wireless communication leads to advance research in LiFi technology through Visible Light Communications (VLC) Technology.

Published: January 2019

Air Susu Ibu (ASI) memiliki manfaat kekebalan bagi bayi, sehingga pemerintah merekomendasikan pemberian ASI ekslusif. Salah satu faktor penyebab rendahnya cakupan ASI Ekslusif adalah karena ibu bekerja. Memerah dan menyimpan ASI dalam ruangan dianggap tidak aman oleh keluarga karena takut basi. Penelitian ini bertujuan untuk menganalisis pengaruh durasi penyimpanan ASI pada 0, 4, 6, dan 8 jam dalam ruangan terhadap kualitas ASI yang dilakukan di lingkungan komunitas dengan melakukan uji laboratorium. Penelitian ini menggunakan desain observasional analitik dengan melibatkan 35 ibu menyusui di Kelurahan Taman Sari Kota Bandung. Pengambilan sampel ASI 50 ml dari setiap subjek penelitian, dan dibagi menjadi 4 (ASI 0, 4, 6, dan 8 jam), kemudian dilakukan uji leboratorium Total Plate Count (TPC) mesofil aerob, enterobacter, jamur, dan identifikasi bakteri patogen. Analisis data dengan menggunakan uji Mc. Nemar untuk melihat pengaruh durasi waktu penyimpanan ASI dalam ruangan terhadap kualitas ASI. Hasil penelitian menunjukkan sampel ASI dengan jumlah total bakteri mesofil aerob > 10 pangkat 5 CFU/ml pada 0 dan 4 jam adalah 2,9%, pada 6 jam 5,7%, dan meningkat menjadi 8,6% pada penyimpanan 8 jam. Sampel ASI dengan jumlah total enterobacter > 10 CFU/ml pada sampel ASI 0 jam adalah 2,9%, pada 4 dan 6 jam 5,7%, dan meningkat menjadi 71,4 % pada penyimpanan ASI 8 jam. Hasil uji statistik menunjukkan ada nya pengaruh durasi penyimpanan terhadap penurunan kualitas ASI 0-4 jam (p=0,032), 0-6 jam (p=0,032), dan 0-8 jam (p=0,002). Kesimpulan : Pada komunitas ini, secara bakteriologis penyimpanan ASI perah aman untuk jangka waktu 6 jam. Semakin lama ASI disimpan dalam ruangan, semakin menurun kualitas ASI.

Purpose: Compare the results of blast furnace smelting efficiency, when chang-ing the qualitative characteristics of the sinter and coke, and the calculated param-eters of the blowing regime of melting.
Methodology: Analysis of technical and economic performance of blast furnaces during periods of work on the agglomerate with different metallurgical characteris-tics and different diameter of the tuyeres.
Findings: The experience of blast furnaces with a volume of 2,700 and 2,000 m3 confirmed a known fact of the dependence of furnace efficiency and coke consump-tion not only through the quality of charge materials, but also through the distribu-tion of the gas flow along the furnace section.
Originality: The technological analysis of the results of the operation of blast furnaces with the volume of 2700 and 2000 m3 with a change of the quality of the sinter and pellets in combination with the change of the blowing regime parame-ters was performed. On the basis of the performed analysis, it was confirmed the expediency of increasing the gas permeability of the charge by improving the quali-ty of the raw materials while increasing the total mechanical energy of the com-bined gas-blast and hearth-gas, which are responsible for the length of the com-bustion zone and the depth of penetration of the gas flow to the center of the blast furnace.
Practical value: Alternation of tuyeres of different diameters along with the im-provement of the quality characteristics of charge materials, additionally contrib-utes to the enhancement of the positive effect due to the expansion of the combus-tion zones in the furnace hearth. And if in this case the total mechanical energy of the mountain gas rises and the depth of penetration of the furnace gas to the fur-nace axis increases, the effect of using high-quality raw materials can be maxim-ized.
Keywords: agglomerate, coke, blowing, tuyeres, gas permeability, quality, total energy.

Published: January 2019

Writing and balancing equations of chemical reactions is one of the \most difficult elements of chemistry education for students, which is why it was decided to analyse part of the process which is the most difficult. The process itself consists of multiple stages. it is important to highlight that the focus of research was not only on balancing the chemical equations. This stage can be independent of chemical skills and knowledge and is based on combinatorial and mathematical skills. The aim of the research was to examine whether using computer simulations can help younger children to balance chemical equations before they start to learn chemistry by using the psychological theory of transfer. It was decided first to teach children how to “make sandwiches” using a computer simulation game. When they have mastered in this activity, they can balance chemical equations. If the children learned how many pieces of cheese, ham and bread would be necessary to “make sandwiches” they began to learn how to balance chemical equations. The children were acquainted with the elements of chemical knowledge necessary to understand the simulation, and then they worked independently with it. Tests were carried out to check the acquired level of ability to balancing chemical equations. The obtained results proved that the balancing of the simple equation of reaction was mastered by over 50% of the children tested. It seems, therefore, a good solution that elements of reconciliation of chemical reaction equations should be introduced at an earlier stage of education, for example during maths lessons.

Indonesia is the third largest coffee producing nation in the world after Brazil and Vietnam. The types and the characteristics of Indonesian coffee are different in each area but the main important factor of consumer acceptance depends on its bitterness level. Chlorogenic acid lactone is a compounds that play an important role as contributor to the coffee bitterness that are formed during the roasting process of coffee bean because of its precursor chlorogenic acid. Chlorogenic acid is commonly found in many plants. One of them can be found in coffee with high concentration. Chlorogenic acid lactone (bitter compound) can be hydrolyzed to chlorogenic acid (non-bitter compound) using hog liver esterase and chlorogenate esterase.  This study aimed to analyze the use of these enzymes to decrease the level of bitterness in coffee. The results indicated that HLE and chlorogenate esterase effectively hydrolyzed chlorogenic acid lactones in coffee.  Based on the sensory test, coffee extracts treated with enzymes were less bitter than the untreated coffee extracts. If it was associated with Indonesian local coffee then the method can be done with chlorogenate esterase that was in accordance with the legal guarantee of halal product.

Hadits sesungguhnya dipenuhi topik-topik yang sangat urgen untuk kita dekati. Seandainya kita benar-benar merealisasikan dengan penuh kesungguhan, tampaklah kepada kita kandungan-kandungan hadits berupa: penerapan syari’at yang cocok untuk setiap waktu dan tempat; sesungguhnya ragam petunjuk hadits bukanlah suatu pelajaran yang mengawang-awang, tetapi menyentuh kejadian-kejadian yang menimpa kelompok manusia baik personal maupun kolektif; Kedudukan Sunnah dalam Islam sebagai sumber hukum para ulama juga telah berkonsesus dasar hukum Islam adalah al Quran dan Sunnah. Dari segi tinkatan dasar Islam, Sunnah menjadi dasar hukum Islam (Tasyri`iyyah) kedua setelah al Quran. Hal ini dapat dimaklumi karena fungsi sunnah sebagai penjelas terhadap alQur’an dan mayoritas sunnah relatif kebenarannya (zhanny ats tsubut), tetapi sebagian kelompok yang oleh ahli hadits disebut ahli bid`ah mengingkari keberadaan dan kedudukan sunnah terhadap al Quran.

Lembaga pendidikan yang terintegrasi kini menjadi pendidikan Islam yang ideal, sebab memiliki beberapa keunggulan diantaranya, waktu belajar lebih lama, tradisi pesantren tetap bisa diterapkan, lulusanya memiliki ilmu pengetahuan lebih, sebab ilmu agama dan umunya diberikan dengan porsi yang seimbang, serrta lulusanya bisa bersaing dengan sekolah atau madrasah diluar pesantren.
Eksekutif Hyper-Performer: Sebuah Potret Budaya Kerja Manajer Kosmopolit
Authors: Zahara Rifqiawati
Published: January 2019

Bekerja terasa dipastikan (terdeterministik seperti dalam alam yang dikuasai oleh suatu hukum objektif), tidak lagi seperti halnya di mana kemampuan seseorang diukur berdasarkan seseorang itu sendiri. Akan tetapi merupakan hasil paksaan dari kekuasaan luar yang asing yang tidak diketahui dari mana dan kemana tujuannya. Hal itu muncul sebagai suatu kesadaran uncontrollable, bahkan sebaliknya lepas dari kemauan dan perjalanan manusia. Sehingga manusia dipaksa menjalani urutan penahapan dan tingkatan perkembangan di bawah suatu perintah. Hal itu yang menggambarkan performa eksekutif profesional dewasa ini. Adanya tuntutan beban kerja yang menumpuk telah menciptakan peran eksekutif yang super sibuk. Muncul distorsi dalam hidup eksekutif yang disebabkan adanya suatu pola yang tidak sistemik dan proporsional. Terutama dalam menetapkan pola kerja sehingga muncul budaya eksekutif “gila kerja” (workaholic). Karena itu sebagai anti tesis workaholic muncul paradigma baru dengan melahirkan performa hyper-performer sebagai alternasi. Dari situ, seberapa jauh eksekutif hyper-performer tersebut dapat tercipta di lingkungan bisnis? Bagaimanakah konsteratif pola kerja eksekutif puncak dalam menempatkan secara tepat hyper-performance dan tidak terjebak pada pola workaholic. Maka tulisan ini berusaha untuk menjelajah konsep tersebut.

Inhibition of Polyamine Biosynthesis Reverses Ca2+ Channel Remodeling in Colon Cancer Cells
Authors: Gutiérrez Lucía G. , Hernández-Morales Miriam , Núñez Lucía , Villalobos Carlos
Published: January 2019

Store-operated Ca2+ entry (SOCE) is the most important Ca2+ entry pathway in non-excitable cells. Colorectal cancer (CRC) shows decreased Ca2+ store content and enhanced SOCE that correlate with cancer hallmarks and are associated to remodeling of store-operated channels (SOCs). Normal colonic cells display small, Ca2+-selective currents driven by Orai1 channels. In contrast, CRC cells display larger, non-selective currents driven by Orai1 and transient receptor potential canonical type 1 channels (TRPC1). Difluoromethylornithine (DFMO), a suicide inhibitor of ornithine decarboxylase (ODC), the limiting step in polyamine biosynthesis, strongly prevents CRC, particularly when combined with sulindac. We asked whether DFMO may reverse SOC remodeling in CRC. We found that CRC cells overexpress ODC and treatment with DFMO decreases cancer hallmarks including enhanced cell proliferation and apoptosis resistance. Consistently, DFMO enhances Ca2+ store content and decreases SOCE in CRC cells. Moreover, DFMO abolish selectively the TRPC1-dependent component of SOCs characteristic of CRC cells and this effect is reversed by the polyamine putrescine. Combination of DFMO and sulindac inhibit both SOC components and abolish SOCE in CRC cells. Finally, DFMO treatment inhibits expression of TRPC1 and stromal interaction protein 1 (STIM1) in CRC cells. These results suggest that polyamines contribute to Ca2+ channel remodeling in CRC, and DFMO may prevent CRC by reversing channel remodeling.

A higher degree of angiogenesis is associated with shortened survival in glioblastoma. Feasible morphometric parameters for analyzing vascular networks in brain tumors in clinical practice are lacking. We investigated whether the macrovascular network classified by the number of vessel-like structures (nVS) visible on three-dimensional T1-weighted contrast–enhanced (3D-T1CE) magnetic resonance imaging (MRI) could improve survival prediction models for newly diagnosed glioblastoma based on clinical and other imaging features. Ninety-seven consecutive patients (62 men; mean age, 58 ± 15 years) with histologically proven glioblastoma underwent 1.5T-MRI, including anatomical, diffusion-weighted, dynamic susceptibility contrast perfusion, and 3D-T1CE sequences after 0.1 mmol/kg gadobutrol. We assessed nVS related to the tumor on 1-mm isovoxel 3D-T1CE images, and relative cerebral blood volume, relative cerebral flow volume (rCBF), delay mean time, and apparent diffusion coefficient in volumes of interest for contrast-enhancing lesion (CEL), non-CEL, and contralateral normal-appearing white matter. We also assessed Visually Accessible Rembrandt Images scoring system features. We used ROC curves to determine the cutoff for nVS and univariate and multivariate cox proportional hazards regression for overall survival. Prognostic factors were evaluated by Kaplan-Meier survival and ROC analyses. Lesions with nVS > 5 were classified as having highly developed macrovascular network; 58 (60.4%) tumors had highly developed macrovascular network. Patients with highly developed macrovascular network were older, had higher volumeCEL, increased rCBFCEL, and poor survival; nVS correlated negatively with survival (r = −0.286; p = 0.008). On multivariate analysis, standard treatment, age at diagnosis, and macrovascular network best predicted survival at 1 year (AUC 0.901, 83.3% sensitivity, 93.3% specificity, 96.2% PPV, 73.7% NPV). Contrast-enhanced MRI macrovascular network improves survival prediction in newly diagnosed glioblastoma.
Role of FoxO Proteins in Cellular Response to Antitumor Agents
Authors: Beretta Giovanni Luca , Corno Cristina , Zaffaroni Nadia , Perego Paola
Published: January 2019

FoxO proteins (FoxOs) are transcription factors with a common DNA binding domain that confers selectivity for DNA interaction. In human cells, four proteins (FoxO1, FoxO3, FoxO4 and FoxO6), with redundant activity, exhibit mainly a positive effect on genes involved in cell cycle, apoptosis regulation and drug resistance. Thus, FoxOs can affect cell response to antitumor agent treatment. Their transcriptional activity depends on post-translational modifications, including phosphorylation, acetylation, and mono/poly-ubiquitination. Additionally, alterations in microRNA network impact on FoxO transcripts and in turn on FoxO levels. Reduced expression of FoxO1 has been associated with resistance to conventional agents (e.g., cisplatin) and with reduced efficacy of drug combinations in ovarian carcinoma cells. FoxO3 has been shown as a mediator of cisplatin toxicity in colorectal cancer. A requirement for FoxO3-induced apoptosis has been reported in cells exposed to targeted agents (e.g., gefitinib). Recently, the possibility to interfere with FoxO1 localization has been proposed as a valuable approach to improve cell sensitivity to cisplatin, because nuclear retention of FoxO1 may favor the induction of pro-apoptotic genes. This review focuses on the role of FoxOs in drug treatment response in tumor cells and discusses the impact of the expression of these transcription factors on drug resistance/sensitivity.

Assessing Heat Waves over Greece Using the Excess Heat Factor (EHF)
Authors: Tolika Konstantia
Published: January 2019

Heat waves are considered one of the most noteworthy extreme events all over the world due to their crucial impacts on both society and the environment. For the present article, a relatively new heat wave index, which was primarily introduced for the study of extreme warming conditions over Australia (Excess Heat Factor (EHF, hereafter)), was applied over Greece (eastern Mediterranean) for a 55-year period in order to examine its applicability to a region with different climatic characteristics (compared to Australia) and its ability to define previous exceptional heat waves. The computation of the EHF index for the period 1958–2012 demonstrated that, during the warm period of the year (June, July, August, and September (JJAS)), Greece experiences approximately 20 days per year with positive anomalous conditions (EHF > 0) with positive statistically significant trends for all stations under study. Moreover, an average of 128 spells with a duration of 3 to 10 consecutive days with positive EHF values were found during the examined 55-year period. As the duration of the spell was extended, their frequency lessened. Finally, it was found that the EHF index not only detected, identified, and described efficiently the characteristics of the heat waves, but it also provided additional useful information regarding the impact of these abnormal warming conditions on the human ability to adapt to them.

Realizing reversible reduction-oxidation (redox) reactions of lattice oxygen in batteries is a promising way to improve the energy and power density. However, conventional oxygen absorption spectroscopy fails to distinguish the critical oxygen chemistry in oxide-based battery electrodes. Therefore, high-efficiency full-range mapping of resonant inelastic X-ray scattering (mRIXS) has been developed as a reliable probe of oxygen redox reactions. Here, based on mRIXS results collected from a series of Li1.17Ni0.21Co0.08Mn0.54O2 electrodes at different electrochemical states and its comparison with peroxides, we provide a comprehensive analysis of five components observed in the mRIXS results. While all the five components evolve upon electrochemical cycling, only two of them correspond to the critical states associated with oxygen redox reactions. One is a specific feature at 531.0 eV excitation and 523.7 eV emission energy, the other is a low-energy loss feature. We show that both features evolve with electrochemical cycling of Li1.17Ni0.21Co0.08Mn0.54O2 electrodes, and could be used for characterizing oxidized oxygen states in the lattice of battery electrodes. This work provides an important benchmark for a complete assignment of all mRIXS features collected from battery materials, which sets a general foundation for future studies in characterization, analysis, and theoretical calculation for probing and understanding oxygen redox reactions.

Quantifying Usability via Task Flow-Based Usability Checklists for User-Centered Design
Authors: Doi Toshihisa , Yamaoka Toshiki
Published: January 2019

In this study, we investigated the effectiveness of a method to quantify the overall product usability using an expert review. The expert review involved a general-purpose task flow-based usability checklist that provided a single quantitative usability score. This checklist was expected to reduce rating variation among evaluators. To confirm the effectiveness of the checklist, two experiments were performed. In Experiment 1, the usability score obtained using the proposed checklist was compared with traditional usability measures (task completion ration, task completion time, and subjective rating). The results demonstrated that the usability score obtained using the proposed checklist shows a tendency similar to that of the traditional measures. In Experiment 2, we investigated the inter-rater agreement of the proposed checklist by comparing it with a similar method. The results demonstrate that the inter-rater agreement of the proposed task flow-based usability checklist is greater than that of structured user interface design and evaluation.
SINR- and MI-Based Maximin Robust Waveform Design
Authors: Wang Bin , Chen Xu , Xin Fengming , Song Xin
Published: January 2019

Due to the uncertainties of radar target prior information in the actual scene, the waveform designed based on radar target prior information cannot meet the needs of detection and parameter estimation performance. In this paper, the optimal waveform design techniques under energy constraints for different tasks are considered. To improve the detection performance of radar systems, a novel waveform design method which can maximize the signal-to-interference-plus-noise ratio (SINR) for known and random extended targets is proposed. To improve the performance of parameter estimation, another waveform design method which can maximize the mutual information (MI) between the radar echo and the random-target spectrum response is also considered. Most of the previous waveform design researches assumed that the prior information of the target spectrum is completely known. However, in the actual scene, the real target spectrum cannot be accurately captured. To simulate this scenario, the real target spectrum was assumed to be within an uncertainty range where the upper and lower bounds are known. Then, the SINR- and MI-based maximin robust waveforms were designed, which could optimize the performance under the most unfavorable conditions. The simulation results show that the designed optimal waveforms based on these two criteria are different, which provides useful guidance for waveform energy allocation in different transmission tasks. However, under the constraint of limited energy, we also found that the performance improvement of SINR or MI in the worst case for single targets is less significant than that of multiple targets.
Extracting Interactions between Flying Bat Pairs Using Model-Free Methods

Published: January 2019

Social animals exhibit collective behavior whereby they negotiate to reach an agreement, such as the coordination of group motion. Bats are unique among most social animals, since they use active sensory echolocation by emitting ultrasonic waves and sensing echoes to navigate. Bats’ use of active sensing may result in acoustic interference from peers, driving different behavior when they fly together rather than alone. The present study explores quantitative methods that can be used to understand whether bats flying in pairs move independently of each other or interact. The study used field data from bats in flight and is based on the assumption that interactions between two bats are evidenced in their flight patterns. To quantify pairwise interaction, we defined the strength of coupling using model-free methods from dynamical systems and information theory. We used a control condition to eliminate similarities in flight path due to environmental geometry. Our research question is whether these data-driven methods identify directed coupling between bats from their flight paths and, if so, whether the results are consistent between methods. Results demonstrate evidence of information exchange between flying bat pairs, and, in particular, we find significant evidence of rear-to-front coupling in bats’ turning behavior when they fly in the absence of obstacles.
Rolling Element Bearing Fault Diagnosis under Impulsive Noise Environment Based on Cyclic Correntropy Spectrum

Published: January 2019

Rolling element bearings are widely used in various industrial machines. Fault diagnosis of rolling element bearings is a necessary tool to prevent any unexpected accidents and improve industrial efficiency. Although proved to be a powerful method in detecting the resonance band excited by faults, the spectral kurtosis (SK) exposes an obvious weakness in the case of impulsive background noise. To well process the bearing fault signal in the presence of impulsive noise, this paper proposes a fault diagnosis method based on the cyclic correntropy (CCE) function and its spectrum. Furthermore, an important parameter of CCE function, namely kernel size, is analyzed to emphasize its critical influence on the fault diagnosis performance. Finally, comparisons with the SK-based Fast Kurtogram are conducted to highlight the superiority of the proposed method. The experimental results show that the proposed method not only largely suppresses the impulsive noise, but also has a robust self-adaptation ability. The application of the proposed method is validated on a simulated signal and real data, including rolling element bearing data of a train axle.
