The minimum information approach to the uncapacitated p-median facility location problem

ABSTRACT In this paper, we apply the minimum information theory to the uncapacitated p-median facility location problem to determine the most probable allocation solution. Indeed, we investigate the bi-level p-median model introduced by [TRANSPORT RES B-METH. 123 (2019) 1–20] in the case that facilities have unlimited capacities. At the upper level, minimizing the cost of establishing facilities and allocating demands is considered, while the most probable allocation solution in the customers’ point of view is determined through the lower level. By adding the Karush-Kuhn-Tucker optimality conditions of the lower-level problem to the upper-level constraints, the bi-level model is reduced to a one-level linear mixed integer problem. Some numerical examples are provided to verify the added value of the proposed model and its solution method.
Response of Morphological Characters and Photosynthetic Characteristics of Haloxylon ammodendron to Water and Salt Stress

In arid desert areas, Haloxylon ammodendron plays an important role in maintaining the ecological balance of desert oases. However, there are few studies on the physiological characteristics of Haloxylon ammodendron under an environmental gradient. Here, we studied the changes in the morphological and photosynthetic characteristics and their correlations in Haloxylon ammodendron in the four habitats of the Ebinur Lake wetland. Our results show that in high-water and high-salt habitats, photosynthesis is affected by “stomata restriction,” while in other habitats, photosynthesis is mainly affected by “non-stomata restriction. ” In addition, when the soil conditions were good, Haloxylon ammodendron chose leaf construction featuring high specific leaf area, while when the soil conditions were worse, it chose an opposite leaf construction model to ensure the optimal allocation of carbon assimilation products in heterogeneous habitats. This study will deepen our understanding of the trade-off strategy between the accumulation and distribution of plant photosynthate in special habitats in arid areas. The results are of theoretical value for analysis of the ecological adaptation mechanisms of plants in arid desert areas.

Discourse markers as a lens to variation across speech and writing

This paper explores the use of the discourse marker (DM) yaʕni (lit. ‘it means’) in spoken and written Egyptian-Cairene Arabic. The DM yaʕni originates in conversational interaction and is symbiotic with its socio-cognitive constraints and goals: it serves to facilitate the verbalization of new or hard-to-activate ideas and to optimize the verbalization of already-introduced ideas, so as to enhance participants’ mutual understanding and involvement. When carried over to written discourse, yaʕni undergoes various forms of adaptation. In casual-personal prose yaʕni is frequently used; however, the distribution of the tokens is different and their function recontextualized. Tokens introducing new ideas are few and acquire symbolic meaning, while tokens introducing elaboration of prior discourse are widely used and serve to evoke conversational interaction. In expository discourse, as reflected in Egyptian Wikipedia data, yaʕni is considerably less frequent and limited to elaborations of concepts and facts. The paper shows the highly context-sensitive function of the DM yaʕni and the ways in which its indexical force, as a marker of conversationality, is either heightened or weakened in writing, depending on the genre in which it is put to use.
Uranyl mixed-ligand complex formation in artificial seawater

AbstractThe stability constants of the mixed uranyl-hydroxo-peroxo-carbonato species have been calculated. By incorporating those and including stability constants and corresponding equilibria into the developed model of seawater species distribution enables the dependence of uranyl species on pH to be evaluated. The calculations show that at seawater conditions (pH = 8), 88.3% of total uranyl-ion is in the form UO2(CO3)4-, 11% is in the form UO2(CO3)2(OH)3-, and 0.5% in the UO2(CO3)(OH)22- mixed-ligand complex form, while in the photic layer, 81.2% of uranyl-ion is in the tricarbonate complex, 10.1% in the form UO2(CO3)2(OH2)3-, 7% as UO2(CO3)2(OH)3-, 0.5% as UO2(CO3)(OH)24- and 0.5% as UO2(O2)22- species.
Effects of Crushed Linseed or Linseed Oil Supplementation on Performance of Dairy Goats and Fatty Acids Profile in Milk Top of Form

In a complete random block design, fifteen lactating Damascus goats (43.5±2 kg body weight) after the first week of lactation, were divided into 3 groups (five goats each) to evaluate effect of linseed or linseed oil as diet supplement on rumen parameters, milk production, milk composition and milk fatty acid profile in lactating goats. Animals were fed on a total mixed ration of 50% concentrates and 50% berseem clover (control), control ration+50g/head/day crushed linseed (LS) and control ration+20 ml/head/day linseed oil (LO) for 90 days. Dry matter intake was not affected by LO or LS. Ruminal volatile fatty acids (VFA) and butyrate proportions were increased (P 0.05) with experimental additives. Milk yield, milk protein and milk fat percent were higher (P 0.05) the proportion of C18:3N3 in milk fat. Total unsaturated fatty acids were increased (P<0.05) with LO; however, insignificantly increased with LS versus control. The proportions of conjugated linoleic acid increased (P<0.05) with addition of LO or LS in the diet. It may be concluded that adding the linseed or linseed oil to lactating goat rations improved the productivity of lactating goats and enhance milk components with no deleterious effects on general health.

The impact of hotel servicescape on customer mindfulness and brand experience: The moderating role of length of stay

ABSTRACT A hotel’s servicescape – its design elements and quality of service – has been shown to predict customers’ brand experience. However, the underlying mechanism of this association is unknown. Based on the stimulus–organism–response (SOR) paradigm, we developed and tested a conceptual model in which servicescape promotes customers’ mindfulness (focused awareness of the present moment), which in turn improves the brand experience. Data were collected from a questionnaire survey of customers in ten 3–5 star hotels in Guangdong Province, China. Structural equation modeling showed that, as hypothesized, customers’ mindfulness mediated the relationship between perceived hotel servicescape and brand experience. In addition, hotel customers’ length of stay negatively moderated the relationship between mindfulness and brand experience. Our study contributes to the literature by integrating concepts from psychology and marketing and expanded the SOR paradigm by introducing a boundary condition of the effect of mindfulness on brand experience.
A visual ethnography of an urban neighborhood

ABSTRACT Atlanta is the fourth fastest gentrifying city in the United States, and a group of five neighborhoods is the subject for this visual ethnography. A problem list was derived from a qualitative study of 20 resident leaders/stakeholders which highlighted problems associated with important representative structures in the community. A visual representation is a way of “seeing, knowing and showing” their spoken and visual culture. This study is a snapshot of a community during a time of rapid change, and illustrated how residents reframed neighborhood deficit discourse as they knew that “change was coming. ” This ethnography also described transformative strategies and how stakeholder and community activism bridged different social networks.
Unprotected sexual practices and associated factors among adult people living with HIV on antiretroviral therapy in public hospitals of Kembata Tembaro Zone, Southern Ethiopia

Introduction Antiretroviral therapy (ART) significantly increases the life expectancy of HIV positive people by improving quality of life as well as enabling them to resume sexual activity. A growing number of people living with HIV became a source of exposure to sexually transmitted infections, including other strains of HIV that place others at risk unless they consistently use condoms. This study assessed the magnitude of unprotected sexual practices and associated factors among adult people living with HIV on ART in public hospitals of the Kembata Tembaro Zone, Southern Ethiopia. Methods a facility-based cross-sectional study was conducted among adult people living with HIV on ART in public hospitals of the zone from March 1-30, 2016. Data were collected by a pretested and structured questionnaire. Binary logistic regression was used to investigate variables, independently associated with the outcome variable. The adjusted odds ratio with 95% CI used to show the strength of the association and a P-value < 0.05 was used to declare the cut-off point in determining the level of significance. Results the study revealed that 40.9% of respondents practiced unprotected sexual intercourse. On multivariate logistic regression analyses, being females, having more than one sexual partner, mean monthly income of <530 Ethiopian birrs/ month, those who had a seropositive partner, a partner of unknown serostatus, and respondents who had insufficient knowledge of HIV transmission and prevention were statically significant with the outcome variable. Conclusion the scarcity of knowledge on HIV transmission, negative attitude towards condom use, non-disclosure status and having more than one sexual partnership increased likelihood of have unprotected sex among the respondents.
Jurisdictional approaches to sustainable resource use

A tropical ecosystems play a vital role in climate regulation, biodiversity conservation, ecosystem services provision, and human livelihoods and culture (Bonan 2008; Seymour and Busch 2016), they remain under threat from deforestation and degradation despite decades of conservation efforts (Hansen et al. 2013; Weisse and Dow Goldman 2019). Research on the effectiveness of both public and private land use policies reveals that only limited progress has been made in halting ecosystem destruction and deforestation in the tropics (Lambin et al. 2014; Weisse and Dow Goldman 2019). Over the past 10 years, jurisdictional approaches to sustainable resource use have emerged (Figure 1) and various initiatives have been implemented (Wolosin 2016; Fishman et al. 2017; Stickler et al. 2018). Jurisdictional approaches have received a considerable degree of political attention through such platforms as the Governors’ Climate and Forest Task Force – a collaboration of 38 subnational governments to reduce greenhouse-gas (GHG) emissions from deforestation and degradation – and the California Tropical Forest Standard (Nepstad et al. 2013a; CARB 2019; GCFTF 2019). The wide diversity of these approaches necessitates the development of a general understanding of what exactly a “jurisdictional initiative” entails. Here, we propose a definition and typology of what constitutes a jurisdictional approach, and discuss the opportunities and challenges such approaches present. The idea of applying practices or policies at the jurisdictional scale to reduce deforestation and degradation in the tropics originated primarily from two sources: REDD+ and sustainable commodity production. First negotiated by the UN Framework Convention on Climate Change in 2005, REDD+ (“Reducing emissions from deforestation and forest degradation and the role of conservation, sustainable management of forests and enhancement of forest carbon stocks in developing countries”; UNFCCC 2008) is a forest conservation framework based on payment-for-ecosystem-services schemes that creates financial incentives for conservation projects through the sale of certified emission reductions (Parker et al. 2009). REDD+ programs were initially implemented at the project level but attention has now shifted to up-scaling REDD+ to the jurisdictional level (Fishbein and Jurisdictional approaches to sustainable resource use
Geological and geotechnical review of gas and mudflow area as mitigation efforts in the risk of failure on Toll Road Project, Banten

The toll project in Banten shows that there is an area of gas burst at one of the locations. The embankment road passes through the gas burst. The geoelectric results that there is a silt/sandy soil layer and rock on the surface (10-20m), the second layer is soft silt to silt (20-40m), and then a rock layer. The second layer has gaps towards the first layer from the bottom layer, which is identified carrying gas and water, which is passed through the gaps to the surface. The seismic refraction also results that there are basins with gaps through the top and bottom of soil layers. The layer which indicates the gas and water carrier line is volcanic, sandy, forming a layer that has undergone deformation and partly a water-bearing layer (sand). The result of LEMIGAS explained that the gas bursts are also not methane that comes from the humus decomposition. The gas bursts are originated from depth and related to petroleum activity. The CO2 content is up to 97.87%, which is poisonous. However, the burst area is open, and the morphology is flat and does not form a cup, this gas spreads out so that the impact is not too pronounced.
Adsorption of the reactive azo dyes onto NH4Cl-induced activated carbon

Background: The efficacy of NH4Cl-induced activated carbon (NAC) was examined in order to adsorb RR198, an azo reactive model dye, from an aqueous solution. Methods: The effects of pH (3 to 10), adsorbent dose (0.1 to 1.2 g/L), dye concentration and contact time on the adsorption efficiency were investigated. Results: The results showed that the removal of dye was highest at a solution pH of 7 and a powder dose of 1.1 g/L. The 85.9%, 72.6% and 65.4% removal of RR198 was obtained for a concentration of 25, 50 and 100 mg/L, respectively, at a relatively short contact time of 30 minutes, and at optimum pH and NAC concentrations of 1 g/L. The experimental data for kinetic analysis illustrated a best fit to the pseudosecond-order model. The study data on equilibrium were modeled using Langmuir, Freundlich and Dubinin–Radushkevich models; the Langmuir equation provided the best fit for the data. Conclusion: Therefore, the NAC appears to be an efficient and appropriate adsorbent for the removal of reactive azo dyes from waste streams.
2-D Localization, Angular Separation and Vital Signs Monitoring Using a SISO FMCW Radar for Smart Long-Term Health Monitoring Environments

A single-input and single-output (SISO) frequency-modulated continuous wave (FMCW) radar architecture is proposed and in vivo demonstrated for remote 2-D localization (range and angular information) and vital signs monitoring of multiple subjects. The radar sensor integrates two frequency scanning antennas which allow angular separation and enable determining a 2-D map (range versus angle) of a room environment from which people can be distinguished from objects and clutter. After technical tests to validate the functionality of the proposed architecture and data processing algorithm, a practical setup was successfully demonstrated to locate human volunteers, at different absolute distances and orientations, and to retrieve their respiratory and heart rate information. Experimental results show that this radar sensor can monitor accurately the vital signs of multiple subjects within typical room settings, reporting maximum mean absolute errors of 0.747 breaths-per-minute and 2.645 beats-per-minute, respectively, for respiration rate and heartbeat. Practical applications arise for Internet of Things (IoT), ambient-assisted living, healthcare, geriatric and quarantine medicine, automotive, rescue and security purposes.
Fair and Privacy-Aware EV Discharging Strategy Using Decentralized Whale Optimization Algorithm for Minimizing Cost of EVs and the EV Aggregator

A key motivation to fasten roll-out of electric vehicles (EVs) to the market is to implement vehicle-to-grid (V2G) functionalities. With V2G in place, EV owners can have an extra freedom to interact their battery energy with power grids, namely, by selling their energy to the grid when their EVs are not in use. On the other hand, EV aggregators and utility companies can leverage the flexibility of the collected energy to implement various ancillary services to the grids, which may significantly reduce costs of, for instance, running spinning reserve of traditional power plants on the grid side. However, this extra freedom also poses practical challenges in terms of how to devise a discharging strategy for a group of EVs that is fair and in some sense optimal. In this article, we present a new design of EV discharging strategy in a typical V2G energy trading framework, while leveraging the whale optimization algorithm in a decentralized manner, a metaheuristic algorithm that has been shown effective in solving large-scale centralized optimization problems. We demonstrate that by using simple ideas of data shuffling and aggregation, one can design an EV discharging strategy in a fair, optimal, and privacy-aware manner, where the privacy refers to the fact that no critical information of EVs should be exchanged with the EV aggregator, and vice versa. The fairness implies that a common discharge rate needs to be sought for all EVs so that no one gets better benefits than others in the same V2G program. Simulation results are presented to illustrate the efficacy of our proposed system.
The Use of Digital Sub-Periosteal Implants in Severe Maxillary Atrophies Rehabilitation: A Case Report

Development in osteointegration and bone-implant interface led through the years to different prosthetic procedures, varying from tilted implant to zygomatic or pterygoid implant. Though feasibility of these prosthetic rehabilitations is to be determined for each patient. Here we suggest a paradigm shift in subperiosteal implant technique, where rigid fixation, load bearing concept, virtual planning and digital engineering are mandatory. A clinical case is reported in order to better explain and help understand the technique.
Low-profile Magneto-electric Dipole Antenna

Here, a magneto-electric dipole-like antenna is developed for Ku-band (12–18 GHz) applications. A low-profile configuration of a magneto-electric dipole antenna has been obtained by the planar arrangement of four shorted patches and L-shaped coax probe. The antenna shows a broad bandwidth response with stable gain and radiation characteristics. The antenna executes an impedance bandwidth between 13.3 and 16.7 GHz with two resonances at 13.9 and 15.6 GHz frequencies. Finally, the antenna has been fabricated and its performance experimentally verified which shows a good agreement with simulated results. The experimental results show −10 dB bandwidth of 11.56%; and peak gain values of 3.9 and 4.6 dBi at 14 and 15 GHz, respectively. On account of the single-layered printed substrate, the proposed antenna can be easily assimilated with associated circuitry.
Improvement of soil moisture storage in clove plantation land using biopore technology and organic material litters

The biopore infiltration hole with organic material litter can increase the soil capacity to accommodate and store soil moisture. This study was aimed to determine the effect of biopores and organic material litter on soil moisture storage and the relationship of climatic conditions on soil moisture storage. The experiment was carried out on clove plantations on Ternate Island, North Maluku from December 2018 to February 2019. This study used a factorial randomized block design. The first factor was the biopores with a depth of 50 cm and 90 cm, and the second factor was 4 types of organic material litters in the form of nutmeg leaves, clove leaves, Guinea grass leaves and a mixture of clove leaves and Guinea grass. The factors observed were total soil water storage and at depths of 0-20, 20-40, 40-60 and 60-80 cm; organic matter content; C/N ratio and soil total N. Data analysis used the GenStat program with analysis of variance test (ANOVA) and Duncan's Multiple Distance Test. Results of the study showed that evaporation and percolation are climatic factors that affect water loss. Increase in soil water storage at 20-40 cm soil depth of 107.56 mm was yielded by the treatment of 50 cm biopore and Guinea grass leaf litter but it was not significantly different from the 50 cm biopore and clove leaf litter + chicken manure treatment. The treatment of biopore and organic material litter also increased the organic matter and soil total N and decreased the soil C/N ratio, but it did not have a significant effect.
Zadeh's Centenary

This is the introductory paper in a special issue on fuzzy logic dedicated to the centenary of the birth of Lotfi A. Zadeh published by International Journal of Computers Communications & Control (IJCCC). In 1965, Lotfi A. Zadeh published in the journal „Information and Control” the article titled „Fuzzy sets”, which today reaches over 117 thousand citations. The total sum of citations for all his papers is above 253 thousand. Based on the notion of fuzzy sets, fuzzy logic and the concept of soft computing emerged, bringing extremely important implications to the field of Artificial Intelligence (AI). In 2017, I published, whith F.G. Filip and M.J. Manolescu, a 42-page long paper in the IJCCC about the life and masterwork of Lotfi A. Zadeh, from which I will use some information in this material [15].
