HIV/HTLV-1 co-infection: a systematic review of current evidence

Human T-cell leukemia/lymphoma virus type 1 (HTLV-1) infection is associated with myelopathy/ tropical spastic paraparesis (HAM/TSP) and adult T cell leukemia/lymphoma (ATLL), which is a malignancy of mature T lymphocytes. HTLV-2 pathogenesis for humans remains undefined. As they share the same transmission routes, co-infection with human immunodeficiency virus (HIV) and HTLV-1 are often reported among the world, mainly among patients living in highly endemic areas like South America and sub-Saharan Africa. Nevertheless, many clinicians are not aware of the potential risks of co-infection with HTLV-1 when treating an HIV patient. Since both viruses infect CD4+ T lymphocytes, scientists have investigated interactions at the cellular and molecular levels, clinical associations, and related complications. Studies have shown that co-infection with HTLV-1 resulted in an increased CD4+ T lymphocyte count, which might be mistaken for immune compatibility, and lead to a delay in the establishment of antiretroviral therapy (ART) in HIV-positive patients. Some authors have observed that co-infection with HTLV-1/HIV-1 can lead to an acceleration of AIDS progression and lessening survival times. Even so, conflicting results and controversies have been reported. These conflicts high-light the requirement of further studies to provide valuable information within this area. In this systematic review, we summarize the current evidence on the co-infection with HTLV-1 among HIV-positive patients, its associated complications, and the impact on progression of AIDS.
Numerical analysis technique for diode-loaded dipole antennas

A circuit model for a double-loaded dipole electric field measurement probe that is valid for frequencies below 10 GHz is developed. A nonnegligible dipole radius and the nonlinear characteristics of the diode are taken into consideration. The dipole lumped-circuit elements and diode capacitances are determined by theoretical means, while the diode V-I characteristics and resistance are determined by a combined theoretical and empirical approach. Newton's iteration method is used to numerically solve the resulting nonlinear differential equation. Experimental measurements on a probe designed for operation between 1 and 1000 MHz are reported and compared with the theoretical results. >

Optimisation of life-of-mine production scheduling for block-caving mines under mineral resource and material mixing uncertainty

ABSTRACT This paper presents a methodology to integrate mineral resource uncertainty from scarce orebody sampling and material mixing uncertainty due to ore flow into the life-of-mine production scheduling of block caving mines. Geological uncertainty is integrated using a Sequential Gaussian Simulation workflow and material mixing uncertainty by simulating material flow using a Cone of Movement concept. A case study is presented in which the uncertainty-based workflow is compared with a deterministic workflow. The stochastic optimisation yields a 4.97% increase in the NPV and a robust production schedule that meets production targets under both sources of uncertainty.
SIMULATION OF A GROUNDWATER ARTIFICIAL RECHARGE IN A SEMI‐ARID REGION OF IRAN

The Bahar aquifer is one of the most economically important aquifers in the western part of Iran, covering the water demands for irrigation supplies. Intensive pumping for irrigation has caused a water table decline. The local water organisation has constructed a water storage structure to augment the groundwater resources. Groundwater recharge using water from the river via 13 dug wells and a related structure has been estimated as 2.7 million m3, for the hydrological year 2002–2003. A three‐dimensional model was developed to predict the aquifer system response. The effect of radial flow was found to be 4 km, and the area covering this recharge more than 40 km2. The results of the numerical model could be used by local authorities and decision makers for groundwater resources management and planning. Finally, it is concluded that aquifer recharge is one environmental solution, as a part of integral water resources management. Copyright © 2010 John Wiley & Sons, Ltd.
Classical Music Specific Mood Automatic Recognition Model Proposal

The purpose of this study was to propose an effective model for recognizing the detailed mood of classical music. First, in this study, the subject classical music was segmented via MFCC analysis by tone, which is one of the acoustic features. Short segments of 5 s or under, which are not easy to use in mood recognition or service, were merged with the preceding or rear segment using an algorithm. In addition, 18 adjective classes that can be used as representative moods of classical music were defined. Finally, after analyzing 19 kinds of acoustic features of classical music segments using XGBoost, a model was proposed that can automatically recognize the music mood through learning. The XGBoost algorithm that is proposed in this study, which uses the automatic music segmentation method according to the characteristics of tone and mood using acoustic features, was evaluated and shown to improve the performance of mood recognition. The result of this study will be used as a basis for the production of an affect convergence platform service where the mood is fused with similar visual media when listening to classical music by recognizing the mood of the detailed section.

Identification of Profane Words in Cyberbullying Incidents within Social Networks

The popularity of social networking sites (SNS) has facilitated communication between users. The usage of SNS helps users in their daily life in various ways such as sharing of opinions, keeping in touch with old friends, making new friends, and getting information. However, some users misuse SNS to belittle or hurt others using profanities, which is typical in cyberbullying incidents. Thus, in this study, we aim to identify profane words from the ASKfm corpus to analyze the profane word distribution across four different roles involved in cyberbullying based on lexicon dictionary. These four roles are: harasser, victim, bystander that assists the bully, and bystander that defends the victim. Evaluation in this study focused on occurrences of the profane word for each role from the corpus. The top 10 common words used in the corpus are also identified and represented in a graph. Results from the analysis show that these four roles used profane words in their conversation with different weightage and distribution, even though the profane words used are mostly similar. The harasser is the first ranked that used profane words in the conversation compared to other roles. The results can be further explored and considered as a potential feature in a cyberbullying detection model using a machine learning approach. Results in this work will contribute to formulate the suitable representation. It is also useful in modeling a cyberbullying detection model based on the identification of profane word distribution across different cyberbullying roles in social networks for future works.
Explaining Knowledge-Sharing Intention in Construction Teams in Hong Kong

Knowledge sharing among construction team members is important for improving project performance and successful project delivery. This study aims to develop an integrative understanding of factors affecting individual knowledge-sharing intention in construction teams in Hong Kong. Based on the widely accepted theory of planned behavior (TPB), a comprehensive research model and corresponding hypotheses were developed. To test the research model and hypotheses, a questionnaire survey was conducted to collect data from pro- fessionals working in construction companies in Hong Kong. Then the data were analyzed by the statistic technique of structural equation modeling (SEM). The results indicate that professionals' knowledge-sharing intention is mainly determined by their attitude toward and perceived behavioral control over knowledge sharing, but weakly influenced by subjective norms regarding knowledge sharing. The research findings also reveal that professionals' attitude toward knowledge sharing is positively influenced by perceptions of knowledge self-efficacy and feedback, while it has no significant relationships with perceptions of economic reward and enhanced personal relationship. In addition, the results show that information and communication technology (ICT) support has a significant effect on professionals' perceived behavioral control over knowledge sharing. This study is one of the first to use the existing theory of social psychology to examine knowledge-sharing behavior in the construction sector. It provides a new direction for studying knowledge sharing in the construction industry. Based on the research findings, several implications are suggested for construction companies to manage professionals' knowledge-sharing behavior in construction teams. Research limitations and recommendations for future studies are also discussed. DOI: 10.1061/(ASCE)CO.1943-7862 . 0000607. © 2013 American Society of Civil Engineers.

A Study of Resource-Constrained Project Optimization with Discounted Weighted Earliness-Tardiness Penalty Costs

This research consider a project scheduling problem with the object of minimizing weighted earliness-tardiness penalty costs, subject to precedence relations among the activities and resource-constrained. Project activities are assumed to have a known deterministic due date, a unit earliness as well as a unit tardiness penalty cost and constant renewable resource requirements. The objective is to schedule the activities in order to minimize the total weighted earliness–tardiness penalty cost of the project subject to the finish–start precedence constraints and the constant renewable resource availability constraints. With these features the problem becomes highly attractive in just-in-time environments. A genetic algorithm (GA) is proposed to solve this model. In addition design of experiments and response surface methodology are employed to tune the GA parameters and to evaluate the performance of the proposed method in 270 test problems. The results of the performance analysis will be shown at the end of this paper.
Ethnobotanical study and utilization of plants in Khok Nhong Phok forest, Kosum Phisai District, Northeastern Thailand

Abstract. Saisor N, Prathepha P, Saensouk S. 2021. Ethnobotanical study and utilization of plants in Khok Nhong Phok forest, Kosum Phisai District, Northeastern Thailand. Biodiversitas 22: 4336-4348. The present study was conducted in Khok Nhong Phok forest, Kosum Phisai District, Maha Sarakham Province, Northeastern Thailand. The forest was surrounded by communities where traditional knowledge has been inherited in the utilization of plants which may disappear over time due to the development of medicinal science and technology. The primary is to study the traditional knowledge in ethnobotanical, collect information about the utilization of plants, and provide the scientific name as the basis for future studies. Data were collected through open-ends interviewing with 30 villagers living in villages around the forest area about their local name, utilization of plants in all 3 aspects, including plants used as food, medicine, and plants used to build houses including parts of plants used. Plant materials and photographs were collected from January to December 2019. Altogether 101 plant species were recorded belonging to 52 families, divided into 3 groups of utilization according to traditional knowledge including 50 species of food plants, 69 species of medicinal plants, and 42 species used for housing, appliances, and fuel. In this study, some plants with more than one type of utilization showed that they were valuable to local people in terms of their uses, and such information can be used as a guideline for the conservation of plant resources in the area to show the importance of cherishing, and maintain valuable resources in the area to remain for future generations.
New technology and new workplaces: call centre careers – a growing reality?

Research to date suggests that career advancement in call centres (CCs) is relatively uncommon with employees often viewing such employment as a stopgap measure before moving on to something better. This study set out to determine whether such scenarios have changed over time since CCs have become more established in their work organisation, information and communication technology (ICT) and management processes. This study particularly focused on training and development initiatives, how employees access training and development, and whether CCs support career development. Using both qualitative and quantitative methods, these issues are examined within 10 Australian CCs of varying size from various sectors. Two-thirds of respondents stated that they intended to develop a career in the industry and 7 in 10 reported that they believed there were promotional opportunities emerging in their current organisation. Despite these findings, the evidence also suggests that more needs to be done both to create coherent career paths and to establish structured, accredited training programmes for CC employees.

Intelligent Airline Seat Inventory Control System

In this article, an "intelligent" airline seat inventory control system is developed. Applications of the system are considered for both nonstop flights and flights with stopovers. The system developed is able to recognize a situation characterized by the number of reservations made by individual passenger classes and the number of canceled reservations at a certain moment in time before departure. The system can also make the appropriate decision without knowing the functional relationships in effect between individual variables. As in other intelligent systems, the "intelligent" airline seat inventory control system proposed here is able to generalize, adapt and learn based on new knowledge and new information. The "intelligent" airline seat inventory control system is based on fuzzy logic. The system makes on-line decisions as to whether to accept or reject any passenger request using established fuzzy rules. The "intelligent" system's results are compared with those of the EMSR model for nonstop flights. The results for flights with stopovers are compared with those obtained using integer programming. The final conclusions are very promising.
Factors influencing the GHG emission consequences of industrial excess heat usage in district heating systems

The potential to increase usage of industrial excess heat is considered to be substantial and an important measure to reach targets of increased energy efficiency and decreased greenhouse gas (GHG) emissions. This paper shows and discusses factors that influence the global GHG emissions consequences of using industrial excess heat in district heating systems. The factors include emissions allocated to the industrial excess heat itself, competing technologies in the district heating system, how emissions related to biomass usage are handled and how different systems are set up and compared. Unavoidable excess heat is defined as excess heat that cannot contribute to decreased usage of primary energy resources in the industrial process. From the examples included in this paper, it can be concluded that if a resource perspective is adopted, it is always preferable to use unavoidable industrial excess heat instead of alternative district heating production from natural gas or biomass-based combined heat and power plants or heat only boilers from a GHG emission perspective.
Influence of human land use and invasive species on beta diversity of tropical ant assemblages

Understanding how biodiversity is distributed is increasingly becoming important under ongoing and projected human land use. Measures of beta diversity, and its partitions, can offer insights for conservation and restoration of biodiversity. We ask how different species, functional groups, and land use contribute to beta diversity, and whether invasive species have a negative influence on beta diversity. We address these questions using ant assemblages (Hymenoptera: Formicidae) at 277 sites distributed across five geomorphic land use types in Goa, India. We recorded 68 species (35 genera, 7 subfamilies) of which 5 were invasive. We classified them into eight functional groups. Oecophylla smaragdina—a common tropical arboreal species, and Anoplolepis gracilepis—a globally significant invasive, contributed the most to beta diversity. Large‐bodied omnivores which may influence soil functions contributed more to beta diversity than small‐bodied predators. Lateritic plateaus contributed most to beta diversity, whereas human‐influenced plantations contributed the least. Beta diversity across sites was related to species turnover, whereas nestedness was more prominent for functional groups. This indicates how species replace one another with change in land use, but functional roles are lost despite such turnover. Sites with human land use had higher incidence of invasive species, and invaded sites contributed less to beta diversity than non‐invaded sites. Human land use strongly influences diversity and distribution of ant assemblages. Land use may spare local species richness, but not functional groups. A small number of invasive species exert negative influence even in very speciose communities.
SIMPLE METHOD FOR CALCULATING THE PEAK TORQUE OF A SWITCHED RELUCTANCE MOTOR: A COMPUTATIONAL INVESTIGATION

The tractive force between two slightly overlapped steel teeth exhibits a remarkably linear relationship with m.m. f. over a considerable range of variables. This occurs despite complex and varying patterns of field at the tooth surfaces, with local flux densities approaching 3 Tesla. A theoretical explanation is not readily available. Results of a computational investigation are reported and analytical approaches considered.
Quasi-static analysis of an optically illuminated directional coupler

In this paper, we present the analysis of an optically illuminated directional coupler using a quasi-static technique. Closed-form expressions of the matching conditions in both the dark and illuminated states are developed. The results obtained by our analytical model are in good agreement with the experimental results as well as those obtained by the monolithic microwave integrated circuit analysis and design simulator (MMICAD). A discussion of the effects of the parameter variations are also included.
Seismic performance of bridges with novel SMA cable‐restrained high damping rubber bearings against near‐fault ground motions

This study presents a novel type of shape memory alloy (SMA) cable‐restrained high damping rubber (SMA‐HDR) bearing, which is particularly suited to near‐fault (NF) regions where the pulsing effect potentially exists in the ground motions. The working mechanism of the bearing is first described, followed by an experimental investigation on a full‐scale SMA‐HDR bearing specimen. The test results confirm the efficient restraining effect offered by the SMA cables, which contribute to 65% and 24.4% of the lateral load resistance and total energy dissipation, respectively, prior to the initial fracture of the SMA cables. The failure of the cables is initiated near the end grip where moderate stress concentration exists at this region. Following the experimental study, the numerical modeling strategy for the bearing is discussed, and a case study is then presented, demonstrating the application of the SMA‐HDR bearings in the Datianba #2 highway bridge, a real project that first adopts the proposed bearings in the world. A simplified design process is introduced for the bridge with novel SMA‐HDR bearings to mitigate the potential damage during strong earthquakes especially the NF ones. The system‐level analysis on the prototype bridge shows that the novel SMA‐HDR bearings equipped with ten 7×7×1.2 SMA cables in each bearing could reduce the average maximum bearing displacement (MBD) by nearly 30% compared with the conventional bridge with HDR bearings. The application of the novel SMA‐HDR bearing can significantly alleviate the pounding effect, especially under the NF earthquakes. The presence of the SMA cables tends to increase the maximum force response of the piers, but this effect is minor and under control.
