Robust Truckload Relay Network Design Under Demand Uncertainty

This research addresses the issue of incorporating demand uncertainty in the strategic design of relay networks for truckload transportation. An existing composite variable mathematical model for the design of hybrid relay networks is extended by developing its robust counterpart. The proposed approach considers uncertainty in the number of truckloads to be dispatched between a pair of nodes in the network which is characterized by a symmetric interval around the expected demand value. A two-step heuristic approach is used to solve the robust model. Several numerical experiments are carried out to study the differences between the solutions obtained with the robust approach and those generated by the existing deterministic model. In particular, we were interested in understating how different levels of uncertainty affect total cost of the system and the configuration of the resulting networks. At the end, numerical results are discussed and directions for future research are presented

Using life cycle assessment for municipal solid waste management in Tehran Municipality Region 20

Background: Due to the lack of a proper waste management system, Tehran Municipality Region 20 is facing economic and environmental problems such as the high costs of a disposal system and source pollution. Life cycle assessment (LCA) is a method for collecting and evaluating the inputs, outputs, and potential environmental impacts of a product system throughout its life cycle. The current study purposed to provide a stable and optimized system of solid waste management in Tehran Municipality Region 20. Methods: The LCA method was used to evaluate various scenarios and compare the effects on environmental aspects of management systems. Four scenarios were defined based on existing and possible future waste management systems for this region. These scenarios were considered with different percentages for source separation, composting, recycling, and energy recovery. Results: Based on the results of this study, Scenario 4 (source separation [14%] + composting [30%] + municipal recycling facility [MRF] [20%] + energy recovery [10%] + landfilling [26%]) was found to be the option with the minimum environmental impact. In the absence of government support and sufficient funds for establishing energy recovery facilities, the third scenario (source separation [14%] + composting [30%] +MRF [20%] + landfilling [36%]) is recommended. Conclusion: The results acquired from this investigation will confirm the belief that LCA as an environmental device may be successfully used in an integrated solid waste management system (ISWMS) as a support tool for decision-making

A Bibliometric Analysis and Visualization of the Scientific Publications of Universities: A Study of Hamadan University of Medical Sciences during 1992-2018

The evaluation of universities from different perspectives is important for their scientific development. Analyzing the scientific papers of a university under the bibliometric approach is one main evaluative approach. The aim of this study was to conduct a bibliometric analysis and visualization of papers published by Hamadan University of Medical Science (HUMS), Iran, during 1992-2018. This study used bibliometric and visualization techniques. Scopus database was used for data collection. 3753 papers were retrieved by applying Affiliation Search in Scopus advanced search section. Excel and VOSviewer software packages were used for data analysis and bibliometric indicator extraction. An increasing trend was seen in the numbers of HUMS's published papers and received citations. The highest rate of collaboration in national level was with Tehran University of Medical Sciences. Internationally, HUMS's researchers had the highest collaboration with the authors from the United States, the United Kingdom and Switzerland, respectively. All highly-cited papers were published in high level Q1 journals. Term clustering demonstrated four main clusters: epidemiological studies, laboratory studies, pharmacological studies, and microbiological studies. The results of this study can be beneficial to the policy-makers of this university. In addition, researchers and bibliometricians can use this study as a pattern for studying and visualizing the bibliometric indicators of other universities and research institutions

BIM-Based Sustainability Rating System for Single-Family Detached Homes

The contemporary social, environmental, and economic challenges and the emerging debate about resiliency have called for a new definition for sustainable buildings. The current green building rating systems are limited in their scope and cannot provide a comprehensive assessment. Hence, an ideal rating system should encompass the triple bottom line (TBL) of sustainability and resiliency with a life cycle thinking perspective. Previous studies highlight a number of issues with green buildings rating systems, such as focusing on point hunting, being complicated, and being expensive in small-scale projects. This research developed a BIM-based sustainability rating method for single-family detached houses (SFDHs). Key performance indicators (KPIs) were used based on an extensive literature review to determine the TBL and resiliency performance. BIM and LCSA were integrated using visual programming. Comprehensive life cycle impact databases were developed using life cycle sustainability assessment. The sustainability performance of SFDHs was compared using the proposed method. Energy accounting was used to validate the results of the proposed method. This research is expected to redefine sustainable buildings and extend the body of knowledge on BIM-based LCSA. In addition, the integration of BIM-LCSA provides a design evaluation platform to enhance the sustainability performance of buildings

CRC-ICM: Colorectal Cancer Immune Cell Markers Pattern Dataset

Colorectal Cancer (CRC) is the second most common cause of cancer death in the world, ad can be identified by the location of the primary tumor in the large intestine: right and left colon, and rectum. Based on the location, CRC shows differences in chromosomal and molecular characteristics, microbiomes incidence, pathogenesis, and outcome. It has been shown that tumors on left and right sides also have different immune landscape, so the prognosis may be different based on the primary tumor locations. It is widely accepted that immune components of the tumor microenvironment (TME) plays a critical role in tumor development. One of the critical regulatory molecules in the TME is immune checkpoints that as the gatekeepers of immune responses regulate the infiltrated immune cell functions. Inhibitory immune checkpoints such as PD-1, Tim3, and LAG3, as the main mechanism of immune suppression in TME overexpressed and result in further development of the tumor. The images of this dataset have been taken from colon tissues of patients with CRC, stained with specific antibodies for CD3, CD8, CD45RO, PD-1, LAG3 and Tim3. The name of this dataset is CRC-ICM and contains 1756 images related to 136 patients. The initial version of CRC-ICM is published on Elsevier Mendeley dataset portal, and the latest version is accessible via: https://databiox.co
