Investigation of Future 5G-IoT Millimeter-Wave Network Performance at 38 GHz for Urban Microcell Outdoor Environment

The advent of fifth-generation (5G) systems and their mechanics have introduced an unconventional frequency spectrum of high bandwidth with most falling under the millimeter wave (mmWave) spectrum. The benefit of adopting these bands of the frequency spectrum is two-fold. First, most of these bands appear to be unutilized and they are free, thus suggesting the absence of interference from other technologies. Second, the availability of a larger bandwidth offers higher data rates for all users, as there are higher numbers of users who are connected in a small geographical area, which is also stated as the Internet of Things (IoT). Nevertheless, high-frequency band poses several challenges in terms of coverage area limitations, signal attenuation, path and penetration losses, as well as scattering. Additionally, mmWave signal bands are susceptible to blockage from buildings and other structures, particularly in higher-density urban areas. Identifying the channel performance at a given frequency is indeed necessary to optimize communication efficiency between the transmitter and receiver. Therefore, this paper investigated the potential ability of mmWave path loss models, such as floating intercept (FI) and close-in (CI), based on real measurements gathered from urban microcell outdoor environments at 38 GHz conducted at the Universiti Teknologi Malaysia (UTM), Kuala Lumpur campus. The measurement data were obtained by using a narrow band mmWave channel sounder equipped with a steerable direction horn antenna. It investigated the potential of the network for outdoor scenarios of line-of-sight (LOS) and non-line-of-sight (NLOS) with both schemes of co- (vertical-vertical) and cross (vertical-horizontal) polarization. The parameters were selected to reflect the performance and the variances with other schemes, such as average users cell throughput, throughput of users that are at cell-edges, fairness index, and spectral efficiency. The outcomes were examined for various antenna configurations as well as at different channel bandwidths to prove the enhancement of overall network performance. This work showed that the CI path loss model predicted greater network performance for the LOS condition, and also estimated significant outcomes for the NLOS environment. The outputs proved that the FI path loss model, particularly for V-V antenna polarization, gave system simulation results that were unsuitable for the NLOS scenario.
Physiological effects of exercise

The physiological response to exercise is dependent on the intensity, duration and frequency of the exercise as well as the environmental conditions. During physical exercise, requirements for oxygen and substrate in skeletal muscle are increased, as are the removal of metabolites and carbon dioxide. Chemical, mechanical and thermal stimuli affect alterations in metabolic, cardiovascular and ventilatory function in order to meet these increased demands.
Optical properties of the “clearest” natural waters

Optical measurements within both the visible and near ultraviolet (UV) parts of the spectrum (305–750 nm) were recently made in hyperoligotrophic waters in the South Pacific gyre (near Easter Island). The diffuse attenuation coefficients for downward irradiance, Kd(λ), and the irradiance reflectances, R(λ), as derived from hyperspectral (downward and upward) irradiance measurements, exhibit very uncommon values that reflect the exceptional clarity of this huge water body. The Kd(λ) values observed in the UV domain are even below the absorption coefficients found in current literature for pure water. The R(λ) values (beneath the surface) exhibit a maximum as high as 13% around 390 nm. From these apparent optical properties, the absorption and backscattering coefficients can be inferred by inversion and compared to those of (optically) pure seawater. The total absorption coefficient (atot) exhibits a flat minimum (~ 0.007 m−1) around 410‐420 nm, about twice that of pure water. At 310 nm, atot may be as low as 0.045 m−1, i.e., half the value generally accepted for pure water. The particulate absorption is low compared to those of yellow substance and water and represents only ~15% of atot in the 305‐420‐nm domain. The backscattering coefficient is totally dominated by that of water molecules in the UV domain. Because direct laboratory determinations of pure water absorption in the UV domain are still scarce and contradictory, we determine a tentative upper bound limit for this elusive coefficient as it results from in situ measurements.
Methimazole‐induced ANCA‐associated vasculitis with diffuse alveolar haemorrhage

Antineutrophil cytoplasmic antibody (ANCA)‐associated vasculitis (AAV) caused by methimazole (MMI) is known to be relatively rare; therefore, the optimal therapeutic approach for these cases remains to be established. A 59‐year‐old man who was treated with MMI for a diagnosis of Graves’ disease was referred to our hospital because of progressive haemoptysis. The patient was diagnosed with diffuse alveolar haemorrhage (DAH) secondary to AAV based on increased inflammatory reactions with positive myeloperoxidase‐ANCA in the serum and the results of bronchoalveolar lavage fluid. MMI was suspected as the cause of the AAV; therefore, the administration of MMI was discontinued. Thereafter, the patient’s symptoms as well as chest radiographic abnormalities completely resolved, in conjunction with normalization of the serum ANCA level. Our experience with this case suggests that DAH secondary to AAV caused by MMI may improve with discontinuation of the offending drug alone, with no other treatment.
Dedifferentiation of prostate smooth muscle cells in response to bacterial LPS

Prostate smooth muscle cells (SMCs) are strongly involved in the development and progression of benign prostatic hyperplasia and prostate cancer. However, their participation in prostatitis has not been completely elucidated. Thus, we aimed to characterize the response of normal SMC to bacterial lipopolysaccharide (LPS).
Missing Sticks: Property Institutions and Income Dissipation in Indian Country

This paper analyzes the economic consequences of property institutions. Federal land reform policy privatized American Indian reservation land in the 1880s. This reform intended to foster economic development on American Indian reservations by creating a system of individual private property. However, these new ownership rights were incomplete and accompanied by restrictions that have led to the fragmentation of land parcels into millions of shared ownership claims. Because land rights on Indian reservations do not include all of the sticks in the traditional property rights bundle, Indians face higher costs for real estate transactions. These additional costs preclude exchange and impede the productive use of reservation-land resources. Using data on Indian land ownership and agricultural leases in 2010, we provide the first quantitative evidence that incomplete property rights have worsened economic outcomes on Indian reservations. Our results show that increased ownership fractionation has reduced the incomes of American Indians on reservations and is associated with lower agricultural lease income, a measure of land productivity.
Text Analytics to Support Sense-Making in Social Media: A Language-Action Perspective

Social media and online communities provide organizations with new opportunities to support their business-related functions. Despite their various benefits, social media technologies present two important challenges for sense-making. First, online discourse is plagued by incoherent, intertwined conversations that are often difficult to comprehend. Moreover, organizations are increasingly interested in understanding social media participants’ actions and intentions; however, existing text analytics tools mostly focus on the semantic dimension of language. The language-action perspective (LAP) emphasizes pragmatics; not what people say but, rather, what they do with language. Adopting the design science paradigm, we propose a LAP-based text analytics framework to support sense-making in online discourse. The proposed framework is specifically intended to address the two aforementioned challenges associated with sense-making in online discourse: the need for greater coherence and better understanding of actions. We rigorously evaluate a system that is developed based on the framework in a series of experiments using a test bed encompassing social media data from multiple channels and industries. The results demonstrate the utility of each individual component of the system, and its underlying framework, in comparison with existing benchmark methods. Furthermore, the results of a user experiment involving hundreds of practitioners, and a four-month field experiment in a large organization, underscore the enhanced sense-making capabilities afforded by text analytics grounded in LAP principles. The results have important implications for online sense-making and social media analytics.
Variables that Influence Elementary School Students' English Performance in Japan

As English has increasingly become popular as a lingua franca, various Asian countries have introduced educational reforms to enhance English instruction. One such reform has been the introduction of English at the elementary school level. Many of the policy decisions on curricula, instructional approach and assessment, however, have been made on a trial-and-error basis. The present study aims to identify those variables that most strongly influence students’ performance in learning English at the elementary school level in Japan. The Junior STEP Silver TEST (a proficiency test that measures basic oral skills among young learners) was administered to 6,541 elementary school students who had received various types of English instruction in Japan. We found that the students’ grade levels and frequencies of instruction received outside of their schools turned out to be good predictors among those variables that we examined. Other variables including the total hours of English instruction at school and the frequencies of instruction led by foreign teachers at school had less influence on students’ performance. Our study also suggests that the one-hour of English instruction commonly taught at schools may exert a different influence on students’ performance between middle grade level and upper grade level students.
New High‐Pressure Phase of CaCO3 at the Topmost Lower Mantle: Implication for the Deep‐Mantle Carbon Transportation

In this study, we have investigated the stability of CaCO3 at high pressures and temperatures using synchrotron X‐ray diffraction in laser‐heated diamond anvil cells. Our experimental results have shown that CaCO3 in the aragonite structure transforms into CaCO3‐VII (P21/c) at 27 GPa and 1,500 K with a negative Clapeyron slope of −4.3(9) MPa/K. CaCO3‐VII is stable between 23 and 38 GPa at 2,300 K and transforms into post‐aragonite at 42 GPa and 1,400 K. Furthermore, it reacts with stishovite, an abundant form of SiO2 in subducted oceanic crust, forming CaSiO3‐perovskite. The occurrence of CaSiO3‐perovskite via the reaction of CaCO3‐VII and stishovite provides an explanation for the observation of the high concentrations of CaSiO3‐perovskite and some amount of CaCO3 in deep‐mantle inclusions. CaCO3‐VII is thus an important carbon‐bearing phase at the topmost lower mantle and may provide necessary carbon to produce deep‐mantle diamonds.
A Probabilistic and Multi-Objective Analysis of Lexicase Selection and ε-Lexicase Selection

Lexicase selection is a parent selection method that considers training cases individually, rather than in aggregate, when performing parent selection. Whereas previous work has demonstrated the ability of lexicase selection to solve difficult problems in program synthesis and symbolic regression, the central goal of this article is to develop the theoretical underpinnings that explain its performance. To this end, we derive an analytical formula that gives the expected probabilities of selection under lexicase selection, given a population and its behavior. In addition, we expand upon the relation of lexicase selection to many-objective optimization methods to describe the behavior of lexicase selection, which is to select individuals on the boundaries of Pareto fronts in high-dimensional space. We show analytically why lexicase selection performs more poorly for certain sizes of population and training cases, and show why it has been shown to perform more poorly in continuous error spaces. To address this last concern, we propose new variants of ε-lexicase selection, a method that modifies the pass condition in lexicase selection to allow near-elite individuals to pass cases, thereby improving selection performance with continuous errors. We show that ε-lexicase outperforms several diversity–maintenance strategies on a number of real-world and synthetic regression problems.

Caveolin-1 Expression in Odontogenic Cysts and Ameloblastomas

Abstract Objective: The aim of this study is to evaluate the caveolin-1 expression in a group of odontogenic cysts and tumors. Material and Method: In this cross-sectional study, the expression of caveolin-1 was evaluated immunohistochemically in 75 samples including 18 cases of dentigerous cyst, 18 odontogenic keratocysts, 3 orthokeratinized odontogenic cysts, 2 calcifying odontogenic cysts and 34 ameloblastomas (solid and unicystic). Results: Positive immunohistochemical reaction was found in 100% of odontogenic cysts and this was significantly more than both unicystic (65%) and solid (55%) ameloblastomas. Conclusion: The present study showed the expression of caveolin-1 in all odontogenic cysts and more than ameloblastomas. The results suggested that absence of caveolin-1 might enhance aggressiveness of odontogenic lesions and could be a useful marker for distinguishing ameloblastomas from other odontogenic lesions. ÖZ Amaç: Bu calışmanın amacı, bir grup odontojenik kist ve tumorde caveolin-1 ekspresyonunu değerlendirmektir. Gereç ve Yöntem: Bu calışmada, caveolin-1 ekspresyonu, 18 dentigeroz kist, 18 odontojenik keratosit, 3 ortokeratinize odontojenik kist, 2 kalsifiye odontojenik kist ve 34 ameloblastomu (solid ve unikistik) iceren 75 olguda immunohistokimyasal olarak değerlendirilmiştir. Bulgular: Odontojenik kistlerin % 100’unde pozitif immunohistokimyasal reaksiyon saptanmıştır. Bu sonuc hem unikistik (% 65) hem de solid (% 55) ameloblastomada saptanandan anlamlı olcude yuksektir. Sonuç: Bu calışma caveolin-1 ekspresyonunun, butun odontojenik kistlerde ameloblastomalardan daha fazla olduğunu gostermiştir. Bulgular caveolin-1 yokluğunun odontojenik lezyonların agresivitesini arttırabileceğini ve ameloblastomaların diğer odontojenik lezyonlardan ayırt edilebilmesi icin yararlı bir gosterge olabileceğini ortaya koymuştur.
Moderating effects of age and experience on the factors influencing the actual usage of cloud computing

Cloud computing technology (CCT) has attracted extensive attention of organizations to enhance their agility, flexibility and competitive advantage. Successful implementation of CCT depends on its acceptance and use by senior IT managers in the organizations. This study proposes an extended technology acceptance model (TAM) to predict actual CCT usage by the managers. A questionnaire is used to collect data. Exploratory and confirmatory factor analyses are performed to analyze the factor structure and measurement model. Structural equation modeling is used to analyze the structural model. The results supported all the hypotheses of the model. The moderating effect of experience and age is also tested through multi-group analysis. Based on findings of the study, implications for CCT usage in the organizations are discussed.
Decrease of inhibitory effect of 2-chlorophenol on nitrification in sequencing batch reactors

ABSTRACT The metabolic and kinetic behaviour of a nitrification process in the presence of 2-chlorophenol (2-CP) was evaluated in two sequencing batch reactors (SBR1, SBR2) inoculated with nitrifying sludge previously exposed to phenolic compounds. The SBR1 was inoculated with sludge previously exposed to 2-CP, while the SBR2 was inoculated with sludge previously exposed to p-cresol. An inhibitory effect of 20 mg 2-CP-C/L on both nitrification processes was observed, as specific rates decreased according to a control assay in the absence of 2-CP. However, the inhibitory effect decreased throughout the cycles. At the end of cycle 6, a stable nitrifying process was observed with the sludge previously exposed to 2-CP (SBR1), as an ammonium consumption efficiency and a nitrate production yield close to 99.6 ± 0.3% and 0.99 ± 0.02 were respectively achieved. Despite a complete ammonium consumption being achieved with the sludge previously exposed to p-cresol (SBR2), partial nitrification was observed as nitrate production yield accounted for 0.28 ± 0.08 and nitrite was accumulated within the culture. Nevertheless, both nitrifying sludges had the ability to completely consume 2-CP. The use of SBR systems with nitrifying sludge previously exposed to 2-CP resulted in a better nitrification performance, thus it may be a good alternative for achieving a stable nitrifying respiratory process where complete and simultaneous ammonium and 2-CP consumption can be acquired. GRAPHICAL ABSTRACT
Food Purchases in a Five-Star Hotel: A Case Study of the Aquila Prambanan Hotel, Yogyakarta, Indonesia

Five-star hotels in developing countries are often presented as importing most of their food and having minimal contacts with the local economy, resulting in high leakages. This study of the Aquila Prambanan illustrates that, in a favourable agricultural setting with a good distribution system, it is possible for a five-star hotel to purchase most of its food locally. The food ordering process, purchasing patterns and purchasing network of the hotel are explored. A strong relationship was found to exist between food purchases and occupancy rates.
Scheduling Stochastic Multi-Stage Jobs to Elastic Hybrid Cloud Resources

We consider a special workflow scheduling problem in a hybrid-cloud-based workflow management system in which tasks are linearly dependent, compute-intensive, stochastic, deadline-constrained and executed on elastic and distributed cloud resources. This kind of problems closely resemble many real-time and workflow-based applications. Three optimization objectives are explored: number, usage time and utilization of rented VMs. An iterated heuristic framework is presented to schedule jobs event by event which mainly consists of job collecting and event scheduling. Two job collecting strategies are proposed and two timetabling methods are developed. The proposed methods are calibrated through detailed designs of experiments and sound statistical techniques. With the calibrated components and parameters, the proposed algorithm is compared to existing methods for related problems. Experimental results show that the proposal is robust and effective for the problems under study.
Role of Ionizing Radiation in Neurodegenerative Diseases

Ionizing radiation (IR) from terrestrial sources is continually an unprotected peril to human beings. However, the medical radiation and global radiation background are main contributors to human exposure and causes of radiation sickness. At high-dose exposures acute radiation sickness occurs, whereas chronic effects may persist for a number of years. Radiation can increase many circulatory, age related and neurodegenerative diseases. Neurodegenerative diseases occur a long time after exposure to radiation, as demonstrated in atomic bomb survivors, and are still controversial. This review discuss the role of IR in neurodegenerative diseases and proposes an association between neurodegenerative diseases and exposure to IR.

Distribution of normalized water-leaving radiances at UV and visible wave bands in relation with chlorophyll a and colored detrital matter content in the southeast Pacific

[1] In-water radiometric measurements were performed in the southeast Pacific (8°S-35°S, 141°W-72°W) from October to December 2004 during the Biogeochemistry and Optics South Pacific Experiment cruise. Normalized water-leaving radiances (nL w (l)) were determined at eight wave bands within the ultraviolet (UV) (305, 325, 340, and 380 nm) and visible (412, 443, 490, and 565 nm) spectral domains. The highest nL w (l) (mW cm A2 sr A1) were recorded in the hyperoligotrophic waters of the South Pacific Gyre, with values increasing with wavelength from 305 (nL w = 0.64) to 380 nm (nL w = 3.18) in the UV range and decreasing from 412 (nL w = 4.46) to 565 nm (nL w = 0.23) in the visible region. The intense nL w (l) observed in the violet-blue domains were attributed to very low absorptions of colored detrital matter (CDM), likely related to a strong photobleaching of colored dissolved organic matter in the surface waters. We evaluated the relationships between the UV, violet, or blue/green wave band ratios of nL w (l) and surface total chlorophyll a (TChl a) concentration and CDM absorption (a CDM (l)). For TChl a, the best correlation was found with the blue/green ratio at 443 nm: TChl a (mg m A3) = 2.37[nL w (443)/nL w (565)] A1.51 (r 2 = 0.86 and RMS error (RMSE) = 23%). By contrast, for a CDM (l), the best correlation was observed when using the UV/green ratio at 325 nm: a CDM (325) (m A1) = 0.16[nL w (325)/nL w (565)] A0.69 (r 2 = 0.82 and RMSE = 16%). These results show the potential role of nL w (l) at UV wave bands for the assessment, through empirical algorithms, of colored detrital matter in the surface oceanic waters.
