The Pharmacological Characterization of Hco-UNC-49, a GABA-gated Chloride Channel from the Parasitic Nematode Haemonchus contortus
(2010-08-01)Compared to mammals, nematodes appear to exhibit a unique GABAergic nervous system. Haemonchus controtus is a parasitic nematode that infects ruminants worldwide. Hco-UNC-49 is a H. contortus GABA-gated chloride channel ... -
Physical and chemical analysis of pig carcass decomposition in a fine sand
(2010-08-01)The development and improvement of methods used for the estimation of the postmortem interval (PMI) is a common area of research in forensic science. This research was conducted to physically and chemically analyze pig ... -
PiXi: an approach to nudge secure password creation
(2023-04-01)Passwords, a first line of defense against unauthorized access, must be secure and memorable. However, people often struggle to create secure passwords they can recall. To address this problem, we design Password inspiration ... -
Playing is creating with PlayTIME: introducing and evaluating a tangible UI-based interactive scenario prototyping system
(2015-02-01)With traditional game prototyping activities, physical and digital game prototyping tasks are commonly separate, often requiring iteration between the two and different personnel to complete physical and digital tasks. ... -
Polymer translocation: a nonequilibrium process
(2017-04-07)3D Langevin dynamics simulations of the capture and translocation of polymers through a nanopore are conducted for several polymer lengths and two different Péclet values (that quantify the drift-diffusion balance of the ... -
Polymorphic Adversarial DDoS attack on IDS using GAN
(2020-12-01)IDS are essential components in preventing malicious traffic from penetrating networks. IDS have been rapidly enhancing their detection ability using ML algorithms. As a result, attackers look for new methods to evade the ... -
Pourbaix diagrams at elevated temperatures: a study of Zn and Sn
(2012-08-01)Metals in industrial settings such as power plants are often subjected to high temperature and pressure aqueous environments, where failure to control corrosion compromises worker and environment safety. For instance, ... -
Predicting mobile application power consumption
(2018-05-01)We present an analysis of battery consumption to predict the average consumption rate of any given application. We explain the process and techniques used to gather the data, and present over 25000 readings collected over ... -
Predicting multi-person dynamics
(2023-12-01)Humans unconsciously model the dynamics of the world around them; for example, we predict the movement of surrounding traffic and pedestrians while driving, or forecast player positions in a game of soccer. Our work builds ... -
Predicting mutation score using source code and test suite metrics
(2012-09-01)Mutation testing has traditionally been used to evaluate the effectiveness of test suites and provide con dence in the testing process. Mutation testing involves the creation of many versions of a program each with a single ... -
Predictive analytics for maintenance activities in nuclear power plants: a feasibility study
(2021-12-01)Nuclear power plants are known for their use of legacy systems and processes. As plants age, the amount of maintenance increases while resources remain finite, leading to unwanted delays, affecting the health of assets and ... -
Preferential proximal policy optimization in reinforcement learning
(2023-12-01)The Proximal Policy Optimization (PPO), a policy gradient method, excels in reinforcement learning with its ”surrogate” objective function and stochastic gradient ascent. However, PPO does not fully consider the significance ... -
Preliminary design of a social asymmetric virtual reality upper-limb exergame for individuals with dementia utilizing insights from caregivers
(2023-10-01)This thesis investigates the usability, task load, cooperative performance, and social presence effects of an asymmetric VR game for upper limb activity in the context of elderly care from the perspective of caregivers. ... -
A privacy preservation framework for smart connected toys
(2019-09-01)Advances within the toy industry and interconnectedness have resulted in the rapid and pervasive development of Smart Connected Toys (SCTs), built to aid children in learning, socialization, and development. A SCT is a ... -
Probing the influence of relative humidity and temperature on the sulfonated silica ceramic carbon electrode for PEM fuel cell operation
(2019-05-01)Operation of fuel cells under low relative humidity (RH) and high temperature is a useful way to cut-down cost and increase performance. However, the Nafion ionomer employed in the electrode of the conventional fuel cells ... -
The production and characterization of ceramic carbon electrode materials for CuCl-HCl electrolysis.
(2013-07-01)Current H2 gas supplies are primarily produced through steam methane reforming and other fossil fuel based processes. This lack of viable large scale and environmentally friendly H2 gas production has hindered the wide ... -
