Lingling Wang, Guozhu Liu, Lijun Sun
Fog-based VANETs (Vehicular ad hoc networks) is a new paradigm of vehicular ad hoc networks with the advantages of both vehicular cloud and fog computing. Real-time navigation schemes based on fog-based VANETs can promote the scheme performance efficiently. In this paper, we propose a secure and privacy-preserving navigation scheme by using vehicular spatial crowdsourcing based on fog-based VANETs. Fog nodes are used to generate and release the crowdsourcing tasks, and cooperatively find the optimal route according to the real-time traffic information collected by vehicles in their coverage areas...

Tan H Nguyen, Mikhail Kandel, Haadi M Shakir, Catherine Best-Popescu, Jyothi Arikkath, Minh N Do, Gabriel Popescu
We present a new approach for retrieving halo-free phase contrast microscopy (hfPC) images by upgrading the conventional PC microscope with an external interferometric module, which generates sufficient data for reversing the halo artifact. Acquiring four independent intensity images, our approach first measures haloed phase maps of the sample. We solve for the halo-free sample transmission function by using a physical model of the image formation under partial spatial coherence. Using this halo-free sample transmission, we can numerically generate artifact-free PC images...

In humans, abnormalities of the vertebral venous system are considered rare but significant causes of radiculopathy and myelopathy. Published information on abnormalities of the canine vertebral venous system is currently lacking. Aims of this retrospective descriptive study were to characterize magnetic resonance imaging (MRI) abnormalities of the vertebral venous system in a population of sighthounds, report prevalence of vertebral venous system abnormalities within that population and explore possible clinical significance...

Sridevi Polavaram, Giorgio A Ascoli
Neuronal morphology is extremely diverse across and within animal species, developmental stages, brain regions, and cell types. This diversity is functionally important because neuronal structure strongly affects synaptic integration, spiking dynamics, and network connectivity. Digital reconstructions of axonal and dendritic arbors are thus essential to quantify and model information processing in the nervous system. NeuroMorpho.Org is an established repository containing tens of thousands of digitally reconstructed neurons shared by several hundred laboratories worldwide...

INTRODUCTION: Selecting a suitable wound dressing for patients with partial-thickness burns (PTBs) is important in wound care. However, the comparative effectiveness of different dressings has not been studied. We report the protocol of a network meta-analysis designed to combine direct and indirect evidence of wound dressings in the management of PTB. METHODS AND ANALYSIS: We will search for randomised controlled trials (RCTs) evaluating the wound-healing effect of a wound dressing in the management of PTB...

The connection density of nearby neurons in the cortex has been observed to be around 0.1, whereas the longer-range connections are present with much sparser density (Kalisman, Silberberg, & Markram, 2005). We propose a memory association model that qualitatively explains these empirical observations. The model we consider is a multiassociative, sparse, Willshaw-like model consisting of binary threshold neurons and binary synapses. It uses recurrent synapses for iterative retrieval of stored memories. We quantify the usefulness of recurrent synapses by simulating the model for small network sizes and by doing a precise mathematical analysis for large network sizes...

Chunliang Yang, Rosalind Potts, David R Shanks
The forward testing effect describes the finding that testing of previously studied information potentiates learning and retention of new information. Here we asked whether interim testing boosts self-regulated study time allocation when learning new information and explored its effect on metamemory monitoring. Participants had unlimited time to study five lists of Euskara-English word pairs (Experiment 1) or four lists of face-name pairs (Experiment 2). In a no interim test group, which was only tested on the final list, study time decreased across successive lists...

Three experiments (N = 100) examine the influence of causal information on overimitation. In Experiment 1, a transparent reward location reveals that the reward is unaffected by nonfunctional actions. When 5-year-olds observe an inefficient and subsequently an efficient strategy to retrieve a reward, they show overimitation in both phases-even though the reward is visible. In Experiment 2, children observe first the efficient then the inefficient strategy. The latter is always demonstrated communicatively, whereas the efficient strategy is presented communicatively (2a) or noncommunicatively (2b)...

INTRODUCTION: Emergent evidence suggests that pelvic floor muscle (PFM) dysfunction contributes to dyspareunia, the experience of pain on vaginal penetration. Electromyography (EMG) is a valuable tool for the assessment of neuromuscular control and could be very useful in enhancing our understanding of PFM involvement in sexual function and in conditions such as dyspareunia. However, PFM EMG must be interpreted within the context of the many factors that can influence findings. AIM: To outline the main factors to consider when evaluating PFM EMG for female sexual function and dyspareunia and to synthesize the literature in which EMG has been acquired and interpreted appropriately in this context...

BACKGROUND: Despite public health efforts to reduce the global burden of leprosy, gaps remain in the knowledge surrounding transmission of infection. Helminth co-infections have been associated with a shift towards the lepromatous end of the disease spectrum, potentially increasing transmission in co-endemic areas. OBJECTIVES: Using this biologically plausible association, we conducted a geographic information systems (GIS) study to investigate the spatial associations of schistosomiasis and leprosy in an endemic area of Minas Gerais (MG), Brazil...

Intentional forgetting of information that has recently been encoded is regarded an active and adaptive process and is widely studied using the item-method or the list-method directed forgetting (DF) paradigm. In the present research, we tested whether inter-individual differences in working-memory capacity (WMC), that have been identified as a relevant predictor of DF within the list-method, are also related to stronger DF effects within the item-method. Furthermore, we investigated relationships between WMC and item-method DF at different processing stages by applying the multinomial storage-retrieval model (Riefer & Rouder, 1992) hierarchically to our data...
