Planning a response to an outbreak of pandemic strain influenza is high public health priority. Three research groups using different individual-based, stochastic simulation models have examined the consequences intervention strategies chosen in consultation with U.S. workers. The first goal simulate effectiveness set potentially feasible strategies. Combinations called targeted layered containment (TLC) antiviral treatment and prophylaxis nonpharmaceutical interventions quarantine,...
This research measures the epidemiological and economic impact of COVID-19 spread in US under different mitigation scenarios, comprising non-pharmaceutical interventions. A detailed disease model is combined with a economy to estimate direct labor supply shock each sector arising from morbidity, mortality, lockdown, as well indirect caused by interdependencies between sectors. During estimates jobs that are workable home used modify supply. Results show trade-offs losses, lives saved...
Given an alphabet $\Sigma$, a (directed) graph G whose edges are weighted and $\Sigma$-labeled, formal language $L\subseteq\Sigma^*$, the formal-language-constrained shortest/simple path problem consists of finding shortest (simple) p in complying with additional constraint that l(p) \in L$. Here denotes unique word obtained by concatenating $\Sigma$-labels along p. The main contributions this paper include following: We show is solvable efficiently polynomial time when L restricted to be...
We empirically study the effect of mobility and interaction between various input parameters on performance protocols designed for wireless ad-hoc networks. An important objective is to routing MAC layer under different parameters. use three basic models: grid model, random waypoint exponential correlated model. The measured in terms quality service measures including (i) latency, (ii) throughput, (iii) number packets received (iv) long term fairness. Three commonly studied are used: AODV,...
We aim to determine the economic and social impact of typical interventions proposed by public health officials preventive behavioral changes adopted private citizens in event a "flu-like" epidemic.
Objective. To present our experience with the Misonix Ultrasonic Bone scalpel in spinal surgery, highlighting its potential applications and advantages. Methods. Between March December 2011, a total of 937 cases were performed at single centre. The Scalpel (MBS) was used 62 these cases. Data collected prospectively using Spine Tango registry. Patient demographics, disease type, surgery complications all recorded along pre- post-operative core measures outcome index (COMI). Results. majority...
ABSTRACT Global airline networks play a key role in the global importation of emerging infectious diseases. Detailed information on air traffic between international airports has been demonstrated to be useful retrospectively validating and prospectively predicting case emergence other countries. In this paper, we use well-established metric known as effective distance data from IATA quantify risk for different countries consequence direct China, compare it against arrival times first 24...
Abstract We use an individual based model and national level epidemic simulations to estimate the medical costs of keeping US economy open during COVID-19 pandemic under different counterfactual scenarios. unmitigated scenario 12 mitigation scenarios which differ in compliance behavior social distancing strategies duration stay-home order. Under each we number people who are likely get infected require attention, hospitalization, ventilators. Given per capita cost for these health states,...
This research conducts a systematic study of human-initiated cascading failures in critical inter-dependent societal infrastructures. The focus is on three closely coupled systems: (i) cellular and mesh networks, (ii) transportation networks (iii) social phone call networks. We analyze cascades that occur infrastructures due to behavioral adaptations response crisis. During crises, changes individual lead altered calling patterns activities, which influence the urban transport network. This,...
Background. The optimal management of odontoid fractures in the elderly population is unclear and this group patients complicated by multiple co-morbidities. This study aimed to determine outcomes after conservative strategies were applied patient group. Methods. We carried out retrospective prospective analyses all with axial cervical spine injuries, at a single centre. included aged over 60 years type II III fractures. Information was gathered on demographics, ASA grading-associated...
We discuss an interaction‐based approach to study the coevolution between sociotechnical networks, individual behaviors, and contagion processes on these networks. use epidemics in human populations as example of this phenomenon. The methods consist developing synthetic yet realistic national‐scale networks using a first‐principles approach. Unlike simple random graph techniques, combine real‐world data sources with behavioral social theories synthesize detailed contact (proximity)...

Network models of infectious disease epidemiology can potentially provide insight into how to tailor control strategies for specific regions, but only if the network adequately reflects structure region's contact network. Typically, is produced by that incorporate details about human interactions. Each detail added renders more complicated and difficult calibrate, also faithful actual structure. We propose a statistical test determine when sufficient has been demonstrate its application used...
We extensively analyze the short (and long) term fairness performance of wireless ad hoc networks. Recently MAC layer such systems has been studied. The primary goal our study is to investigate how multi-hop routing in an network affects layer. demonstrate that higher-level protocols must also be considered when studying fairness. behavior a using DSR (dynamic source routing) and DSDV as protocols. used IEEE 802.11. carried out for wide range independent parameters.
