To improve cancer survival rates and prognosis, one of the first steps is to improve our understanding of contributory factors associated with cancer survival. Prior research has suggested that cancer survival is influenced by multiple factors from multiple levels. Most of existing analyses of cancer survival used data from a single source. Nevertheless, there are key challenges in integrating variables...
Many applications have a higher starting torque requirement and it is sometimes a struggle to provide smooth starting performance. VFD starts are known to reduce starting stresses but may not always provide the best overall solution when economics, performance and process control are considered. This paper will review considerations for new and retrofit applications, touching on torques required by...
This paper reports two microfluidic devices for isolating circulating tumor cells (CTCs) in blood samples of pancreatic cancer patients. These devices consist of micromixers or micropillars for enhancing the interactions between tumor cells and capture agents, which are immobilized onto the surfaces of microchannels and microfeatures. Both antibodies and aptamers, as well as their ensemble, have been...
Simulation is widely used to predict the performance of complex systems. The main drawback of simulation is that it is slow in execution and the related compute experiments can be very expensive. On the other hand, analytical methods are used to rapidly provide performance estimates, but they are often approximate because of their restrictive assumptions. Recently, Extended Kernel Regression (EKR)...
This paper describes the Front-X, a dual-polarized X-band Phased Array Weather Radar system currently being developed at Colorado State University. The architecture of this mobile radar is presented, with a description of the antenna array, waveform synthesis and digital receiver/pulse compressor modules. Initial observations made with the phased array weather radar are also shown.
The generalizability (external validity) of clinical trials has long been a concern for both clinical research community as well as the general public. Results of trials that do not represent the target population may not be applicable to the broader patient population. In this study, we used a previously published metric Generalizability Index for Study Traits (GIST) to assess the population representativeness...
Ultrasound image segmentation is still a challenging issue in various applications to extract the meaningful information for disease diagnosis in the athletes. Generally, ultrasound images could be suffering from some problems such as speckle, attenuation, signal dropout and shadows which make the segmentation process more complicated and inefficient. Due to these problems, traditional segmentation...
‘You cannot step into the same water twice’, in other words ‘change is law of life’ and ‘everything changes and nothing stands still’ said Heraclitus, a prominent Greek Philosopher. In this similar line Changes in consumer behavior is not an exception as consumers are a dynamic and progressive and who change themselves according to the signs of time. This paper delves into the fact of changing consumer...
“Take away all my wealth, take all my machines but leave my men alone and I will become Hendry Ford again” said Henry Ford. These words of Henry highlight and uphold the ‘human resource’ as a prime resource before all other resources. It's in fact true that the well utilized human resource never leads to disparity or failure. In this line, the role of performance appraisal has a tremendous role to...
Commercial operational amplifiers are common components in electronics in a high radiation environment such as for spacecraft. We performed proton and heavy-ion testing of selected commercial instrumentation and precision operational amplifiers. Based on these tests, we present cross section results for single event effects.
X-ray fluorescence computed tomography (XFCT) is an emerging imaging modality that maps the three-dimensional distribution of elements, generally metals, in ex vivo specimens and potentially in living animals and humans. Building on our previous synchrotron-based work, we experimentally explored the use of a benchtop X-ray fluorescence computed tomography system for mapping trace-metal ions in biological...
Hostile fire detection is a critical component of situational awareness in the asymmetric battlefields of ongoing and future conflicts. The ability to detect and localize sources of hostile fire in difficult environments can dramatically increase the survivability of dismounted warfighters. Existing individual acoustic hostile fire sensors provide useful information, but are prone to heading errors,...
Smart sensors are becoming an integral part of the evolving technology landscape; their ability to share reduced data over networks enables live data fusion, which significantly improves sensor performance and situational awareness. A lightweight, mobile acoustic sensor network has been used as an infrastructure to layer multi-sensor fusion algorithms, for detection of impulsive events such as gunfire...
Controlling the machine state towards the optimum trade-off between cycle time and power demand improves machine sustainability in manufacturing. This paper presents a dynamic programming approach for optimally controlling a single server manufacturing system with finite capacity and Poisson arrivals (M/M/1/K). The admission of parts into the system is controlled together with the service rate of...
Magnetic skyrmions are arguably the smallest stable magnetic configuration in films, and therefore could be the ultimate magnetic storage bit [1,2]. They have also triggered a wide interest due to the new fundamental phenomena related to their topology. Numerical simulations have shown that the interfacial Dzyaloshinskii-Moriya interaction (DMI) can stabilize such skyrmions in nanoscale disks or tracks...
Binary information encoded within the spin of carriers can be transferred into corresponding right or left-handed circularly polarized photons emitted from an active semiconductor medium via carrier-photon angular momentum conversion. In order to attain maximized spin-injection at out-of-plane magnetic remanence, a number of material systems have been explored as possible solid-state spin injectors...
This work describes the designing of a Graphics Processing unit that deals with image processing. Graphics Processing Unit (GPU) is an important factor when it comes to large computing. Images and videos that are having large data can be processed efficiently in GPU by exploiting its feature of parallel execution. Digital image processing implemented on hardware provides higher processing speed and...
