History And Current Status Of Mediterranean Spotted Fever (Msf) In The Crimean Peninsula And Neighboring Regions Along The Black Sea Coast, Muniver T. Gafarova, Marina E. Eremeeva

Biostatistics, Epidemiology & Environmental Health Sciences: Faculty Publications

Mediterranean spotted fever (MSF) is a tick-borne rickettsiosis caused by Rickettsia conorii subspecies conorii and transmitted to humans by Rhipicephalus sanguineus ticks. The disease was first discovered in Tunisia in 1910 and was subsequently reported from other Mediterranean countries. The first cases of MSF in the former Soviet Union were detected in 1936 on the Crimean Peninsula. This review summarizes the historic information and main features of MSF in that region and contemporary surveillance and control efforts for this rickettsiosis. Current data pertinent to the epidemiology of the disease, circulation of the ticks and distribution of animal hosts are discussed …

Never Too Old For A Field Trip: Exploring Community Assets For Middle Grades Literacy Integration, Christine L. Craddock, Stacie K. Pettit 2949136

Current Issues in Middle Level Education

Middle Grades teacher candidates participated in a “field trip” in an Integrated Reading course to model best practices in culturally responsive teaching. The college students visited their downtown city including a regional art museum and memorial sculpture garden commemorating local Black history to experience and contemplate possibilities for literacy integration in their pedagogy. Teacher candidates were encouraged to explore and understand community culture, history, and assets with respect to their future students’ lives, identities, interests, and experiences, and how these considerations should motivate their instructional decision making with literacy applications. A follow-up discussion was facilitated by the course professor along …

Individual Difference Correlates Of Being Sexually Unrestricted Yet Declining An Hiv Test, Nicholas S. Holtzman, Stephen W. Carden, Stacy W. Smallwood, Janice Steirn, S. Mason Garrison

Mathematical Sciences: Faculty Publications

Which individual differences accurately predict one’s decision to get tested for human immunodeficiency virus (HIV), and do individuals who have regular short-term sex get tested at higher rates? Two studies—one lab study (total valid N = 69, with n = 20 who were tested) and one involving a student health center (valid N = 250, n = 4 who were tested)—involved participants (total valid N = 319, with n = 24 who got tested) taking a number of personality and individual difference measures, including the dark triad (Machiavellianism, narcissism, and psychopathy). Then, in both studies, participants had the opportunity to …

The Public Health Impact Of Paxlovid Covid-19 Treatment In The United States, Yuan Bai, Zhanwei Du, Lin Wang, Eric H. Y. Lau, Isaac Fung, Petter Holme, Ben Cowling, Alison Galvani, Robert Krug, Lauren Ancel Meyers

Biostatistics, Epidemiology & Environmental Health Sciences: Faculty Publications

The antiviral drug Paxlovid has been shown to rapidly reduce viral load. Coupled with vaccination, timely administration of safe and effective antivirals could provide a path towards managing COVID-19 without restrictive non-pharmaceutical measures. Here, we estimate the population-level impacts of expanding treatment with Paxlovid in the US using a multi-scale mathematical model of SARS-CoV-2 transmission that incorporates the within-host viral load dynamics of the Omicron variant. We find that, under a low transmission scenario (Re∼1.2) treating 20% of symptomatic cases would be life and cost saving, leading to an estimated 0.26 (95% CrI: 0.03, 0.59) million hospitalizations averted, 30.61 (95% …

Characteristics And Source-Specific Health Risks Of Ambient Pm2.5-Bound Pahs In An Urban City Of Northern Taiwan, Yu-Chieh Ting, Chun-Hung Ku, Yu-Xuan Zou, Kai-Hsien Chi, Jhy-Charm Soo, Chin-Yu Hsu, Yu-Cheng Chen

Biostatistics, Epidemiology & Environmental Health Sciences: Faculty Publications

Polycyclic aromatic hydrocarbons (PAHs) with highly toxic compounds mainly exist in small-sized particles and can induce considerable human health risks. Studies on PM2.5-bound PAHs and their source-specific human health risks still remain scarce. Daily PM2.5 samples (n = 119) were collected every three days from 2016 to 2017 in Taipei city, Taiwan. Fifteen PAHs in PM2.5 were analyzed via gas chromatography tandem mass spectrometry (GC/MS-MS). We utilized a positive matrix factorization (PMF) model, diagnostic ratios, and potential source contribution function (PSCF) to identify the origins of PM2.5-bound PAHs. The annual concentration of total PAHs (TPAH) was 0.79 ± 0.67 ng …

The Gamma-Signless Laplacian Adjacency Matrix Of Mixed Graphs, Omar Alomari, Mohammad Abudayah, Manal Ghanem

Theory & Applications of Graphs

The α-Hermitian adjacency matrix H_α of a mixed graph X has been recently introduced. It is a generalization of the adjacency matrix of unoriented graphs. In this paper, we consider a special case of the complex number α. This enables us to define an incidence matrix of mixed graphs. Consequently, we define a generalization of line graphs as well as a generalization of the signless Laplacian adjacency matrix of graphs. We then study the spectral properties of the gamma-signless Laplacian adjacency matrix of a mixed graph. Lastly, we characterize when the signless Laplacian adjacency matrix of …

Prospective On Automation For Omnichannel Services And The Need For New Robotic Solutions For Store Fulfillment Operations, Jennifer Pazour, Manmit Padhy, Georg Fischer, Joyjit Bhowmick, Sebastian Köhler, Gideon Arndt, Kai Furmans

16th IMHRC Proceedings (Dresden, Germany- 2023)

As businesses offer omnichannel services, such as buy-online-pickup-in-store, more logistical processes need to be conducted within or close to a retail environment. For retailers who adopt a store fulfillment concept, order picking for online orders is conducted inside a store environment and is in addition to the logistic processes required to support in-store customer requests. A store fulfillment approach has the advantage of enabling inventory, labor, infrastructure, and automation to be pooled for online orders, in-store customers, and return processing. Yet, the design and operation of logistical tasks completed in a retail environment is more challenging and requires considering …

A Fluid Flow Queuing Network Model For Performance Analysis Of Bulk Liquid Terminals, Debjit Roy, Werner Scheinhardt, Jan-Kees Van Ommeren

16th IMHRC Proceedings (Dresden, Germany- 2023)

Bulk liquid terminals play a crucial role in enabling the timely discharge and loading of liquid from the tankers and also facilitating oil transport to the hinterland via pipelines and external trucks. However, the speed of operations (and demurrage costs in the likely event of vessel handling delays) depends on the capacities of all terminal resources including berth, loading arms, and storage tank farms. Today, there is a limited understanding of how the interactions among the resources affect the overall vessel sojourn time performance. Using an integrated fluid flow simulation model of a bulk liquid terminal, we are able to …

Working Together- Scheduling Operations In Assisted Order Picking, Jelmer Pier Van Der Gaast

16th IMHRC Proceedings (Dresden, Germany- 2023)

Warehouse operations are becoming increasingly competitive due to the rise of e-commerce and same-day deliveries. To increase operational productivity, it is important to organize order picking as efficiently as possible. A new technology that is relatively cheap is assisted order picking (AOP). AOP involves human order pickers and pick robots working together to ensure customer orders are picked. It is easy to apply, does not require a major reconfiguration of the whole warehouse, and is scalable. In this paper, two variants of AOP are studied, and a mathematical optimization model is developed to minimize the makespan of picking a wave …

Optimization Of Cargo Handling Equipment At The Airport, David Sourek

16th IMHRC Proceedings (Dresden, Germany- 2023)

Delaying an aircraft during ground handling costs the airline a lot of money. In critical situations, it is even possible that some flights have to be canceled due to delays. It is therefore the endeavor of all personnel involved in ground operations that they proceed without delay. This paper shows what methods can be used to optimize the required number of handling equipment and what can affect its number.

Designing Facilities To Improve Flexibility: Zone-Based Dynamic Facility Layout, Sadan Kulturel-Konak, Abdullah Konak

16th IMHRC Proceedings (Dresden, Germany- 2023)

This paper considers solving the unequal area Dynamic Facility Layout Problem (DFLP) using a zone-based structure. Zone-based layouts have significant advantages, such as being easily transferable to a detailed layout with innately included possible aisle structures; therefore, they can be fitted to the unique needs of the layout designers. The unequal area DFLP is modeled and solved using a zone-based structure, which is referred to as ZDFLP, where the dimensions of the departments and material handling system input/output (I/O) points are decision variables. A two-phase matheuristic, which directly operates on Problem ZDFLP without requiring an encoding scheme of the problem, …

On Logistics And Motion Planning - An Informal Axiomatic Approach, Moritz Roidl

16th IMHRC Proceedings (Dresden, Germany- 2023)

Through the introduction of an informal axiomatic framework, this paper aims to contribute to the development of a general theory of logistics, which is currently still a blindspot in logistics research. It aims to combine the precision of robotic motion planning concepts with established logistics terminology, forging a link that balances the robustness of a mathematically rigorous theory with the rich semantic understanding inherent in logistics models. Centered around the notion of designing a logistic space, a possible way of structuring this space by grid-based and continuous spatial structures is discussed. The axiomatic framework is extended to include a new …

Handling Disruptions In A Network With Cross-Docking, Vishal Badyal, Fahim Ahmed, Nikhil Aditya Eti, Nathan Huynh, William Ferrell

16th IMHRC Proceedings (Dresden, Germany- 2023)

Cross-docking (CD) is a commonly used technique to consolidate freight for more efficient delivery to customers; CD is continuing to see increased use by companies. Synchronization of inbound and outbound freight is clearly critical to operations and so is having the cross-dock able to support the freight flow with available doors and material handling equipment. The latter is particularly important when there is a disruption in the inbound freight. One delayed truck can impact several outbound trucks. A methodology is proposed to address explicitly both the scheduling of trucks and material handling within the CD. Two models are proposed – …

Decision Rules For The Robotic Mobile Fulfillment System Of A Pcb Assembly Factory Warehouse, Ching-Jung Ting, Hendra Permana, Hsien-Mi Meng

16th IMHRC Proceedings (Dresden, Germany- 2023)

During the COVID-19 pandemic period, global supply chains are disrupted and most of the workers cannot go to the factories to work. Robotic mobile fulfillment system (RMFS) is one of the new types of autonomous, parts-to-picker system, designed especially for e-commerce warehouses. The system can increase the productivity of pickers. However, no research discussed the application of RMFS in manufacturing sector. This research simulates the picking process of a factory warehouse and studies the operational sub-problems which include order line assignment, station selection, pod selection, and pod storage assignment. Different decision rules of each operational problem are proposed and evaluated. …

5g Opportunities In Warehousing, Roshan George, Natalie S. Cherbaka, Kimberly Ellis

16th IMHRC Proceedings (Dresden, Germany- 2023)

As capabilities of fifth generation wireless technology (5G) improve, adoption will go beyond current urban cellular networks into industrial settings enabling the IoT landscape. 5G primarily delivers value by enhancing mobile broadband through ultra-reliable, low-latency signals and massive machine-type communications. With the concurrent development of 5G and industrial automation, replacing Wi-Fi and LTE services with 5G networks offers an opportunity to enhance scheduling, latency, jitters, and redundancy in demanding applications. Additionally, the equipment redesigns and upgrades to operate in 5G will pave the way for innovation in operational strategies previously constrained by network capabilities. In this paper, we consider the …

Performance Analysis Of Unequal Area Facility Layout Problem When Superimposed By Load Transport And Empty Flow Networks, Ardavan Asef-Vaziri, Cory Taylor

16th IMHRC Proceedings (Dresden, Germany- 2023)

Given the area of the workcenters and the required loaded flow matrix between pairs of workcenters, the unequal facility layout problem (UA-FLP) is concerned with a continuous model for the arrangement of the workcenters under a loaded flow-distance objective function. In UA-FLP models, distances are measured between the centroids of the workcenters on arbitrary bidirectional free rectilinear flow paths. While these assumptions may work for gantry cranes, they are far from reality for vehiclebased material transport systems. In this study, starting from the block layouts obtained under the UA-FLP assumptions, we move towards superimposing them by material transport networks and …

Modeling Post-Disruption Equilibrium For Circular Supply Chains And New Measures For Resilience, Sangwoo Park, Ilaria Giannoccaro, Layek Abdel-Malek

16th IMHRC Proceedings (Dresden, Germany- 2023)

Among concerns on sustainability and environmental protection, there is a growing interest in the adoption of circular supply chains (CSCs). This work introduces a firstcut approach to capturing the resilience of supply chains and their components related to material handling. We develop a methodology for computing the new equilibrium states after disruptions and use this to measure the resilience of circular supply chains. Numerical simulations illustrating our concept are performed on a synthetic toy-example. In addition, we introduce a secondary measure of resilience that encapsulates the transient stages of a supply chain after disruption. This measure is able to highlight …

Designs Of Puzzle Based Storage Systems With Unidimensional Cells, Hector J. Carlo, Andres Blanco

16th IMHRC Proceedings (Dresden, Germany- 2023)

A paradigm for puzzle-based storage systems (PBS) is that all cells have the capacity of transporting loads horizontally and vertically. This research challenges this paradigm by considering unidimensional PBS, where some cells are limited to either horizontal or vertical movements. PBS with some unidimensional cells are referred to as unidimensional PBS. A linear program (LP) formulation is presented to find the optimal load retrieval path using a single-escort in a unidimensional PBS. The LP is solved recursively to understand the tradeoffs of unidimensional designs for a 4×4 system. It is concluded that unidimensional PBS can be designed such that the …

Current Challenges And Approaches In Route Selection Of A Fleet Of Amr, Thorsten Schmidt, Karl-Benedikt Reith, Frank Schulze

16th IMHRC Proceedings (Dresden, Germany- 2023)

With the trend in intralogistics from Automated Guided Vehicles (AGV) to free ranging Autonomous Mobile Robots (AMR), vehicle-based transportation systems further in-crease their flexibility, scalability and performance. However, these benefits come at the cost of an increase in complexity caused by the AMRs’ high degree of freedom, e.g. when it comes to the determination of routes. In addition to manifold approaches to the selection of a global route and the avoidance of local routing con-flicts with other vehicles, this paper discusses the idea of applying a set of offline defined rules. Lowering the AMRs’ degree of free-dom, these rules enable …
