Facial Color Management for Mobile Health in the Wild

Nowadays, mobile technologies have changed the patient routine health care and management. With a large amount of mobile health applications developed, massive and valuable health data are possibly collected with a smart mobile phone in hand. Facial color images are recently proved to be available and effective for health condition diagnosis both in modern medicine and ancient medicine perspectives. One significant issue of facial color health condition diagnosis system is color management, in which its primary procedure is to obtain reliable and device-independent facial color images in the wild. The solution is known as utilizing color correction technology to recover the intrinsic color properties of facial skin. However, current color correction approaches are hard to meet the need of mobile health management in the wild, due to some limitations of precision-challenged algorithm, inconvenient color imaging device, strong scenario assumption, and so forth. Therefore, in this paper, we consider several facial skin color characteristics and show that it is valuable to build facial color related correction model for facial color images in the wild. Then we propose two kinds of facial color correction strategies to realize the facial color management of mobile health in the wild. The first one is reference-based approach, and the other one is skin-based approach without requirement of colorchecker. Experimental results with qualitative and quantitative assessments on the indoor and outdoor scenarios demonstrate that the proposed reference-based approach is more outstanding than our previous method and other color constancy methods. In addition, given a facial color image only, the skin-based method can still achieve effective results compared with other color constancy methods.
Validation of Numerical Models of Portable Wireless Devices for Near-Field Simulation

The major contribution of the paper is a theoretical proof of the equivalence between two approaches of near-field validation techniques for the numerical models of personal wireless communication devices. The current validation practice is to compare measured and computed electromagnetic field or specific absorption rate distributions. A new validation technique introduced by the authors recently compared measured and computed antenna input-impedance changes while the near field is systematically perturbed by a dielectric control object. The proof of the equivalence is based on two novel formulas derived here: a reaction impedance-change formula, and an error formula that establishes a quantitative relationship between the errors of the impedance changes and the near-field values. The equivalence of the two validation techniques is verified experimentally too by comparing measurements and computations for a planar-inverted F antenna. By performing numerical experiments for two types of printed-circuit board antennas, it is also proved here the first time that the new validation technique is feasible even if the geometric and material properties of the control object are such that the Born approximation can be introduced in the impedance-change formula.
Pulsed Eddy Current Testing of Thermally Aged and Cold-Rolled Fe–Cu Alloys

In this work, Fe-1wt%Cu alloy samples exposed to thermal aging and cold rolling (CR) were studied as an attempt to emulate material degradation in neutron irradiated nuclear reactor pressure vessels. CR was tested by pulsed eddy currents (PECs) using a directional probe which was rotated in the sample plane. Normalized PEC signals, represented by typical “figure of eight” on the polar plot, showed very strong anisotropy, which has a monotonic dependence on the amount of cold work. Since the normalized PEC signals represent the response due to electrical conductivity and reduce the ferromagnetic effect, it is concluded that the change is due to anisotropic magnetoresistivity of the rolled steel. The normalized difference PEC responses have been found to be described by the quadratic dependence of the cosine of in-plane angle shifted by an angle, which is believed to correspond to slip planes of dislocations induced by rolling. The technique advantageously combines effects of rolling on electrical conductivity and magnetic permeability and does not require referencing to an untreated standard, which is important for future material and device health management.
Repetitive Scenario Design

Repetitive Scenario Design (RSD) is a randomized approach to robust design based on iterating two phases: a standard scenario design phase that uses <inline-formula> <tex-math notation="LaTeX">$N$</tex-math></inline-formula> scenarios (design samples), followed by randomized feasibility phase that uses <inline-formula> <tex-math notation="LaTeX">$N_{o}$</tex-math></inline-formula> test samples on the scenario solution. We give a full and exact probabilistic characterization of the number of iterations required by the RSD approach for returning a solution, as a function of <inline-formula> <tex-math notation="LaTeX">$N$</tex-math></inline-formula>, <inline-formula> <tex-math notation="LaTeX">$N_{o}$</tex-math></inline-formula>, and of the desired levels of probabilistic robustness in the solution. This novel approach broadens the applicability of the scenario technology, since the user is now presented with a clear tradeoff between the number <inline-formula> <tex-math notation="LaTeX">$N$</tex-math></inline-formula> of design samples and the ensuing expected number of repetitions required by the RSD algorithm. The plain (one-shot) scenario design becomes just one of the possibilities, sitting at one extreme of the tradeoff curve, in which one insists in finding a solution in a single repetition: this comes at the cost of possibly high <inline-formula> <tex-math notation="LaTeX">$N$</tex-math></inline-formula>. Other possibilities along the tradeoff curve use lower <inline-formula> <tex-math notation="LaTeX">$N$</tex-math></inline-formula> values, but possibly require more than one repetition.

A Generalized Circle Diagram Approach For Global Analysis Of Transmission System Performance

The global response of a power system to variations in the node constraints is considered. The relation of specific system variables to independent node parameters is calculated using a numerical technique which provides a generalization of the elementary power circle diagram. Curves which show system performance during disturbances, tradeoffs between design parameters, voltage stability limits and multiple power flow solutions are produced. The theory of the method is presented through geometrical concepts, and its application is illustrated with several examples.
Analytical calculation of leakage inductance for low-frequency transformer modeling

In this paper, a new method for the calculation of leakage inductances between short-circuited windings is proposed. The main objective is to find an analytical alternative to the finite element method (FEM) for the computation of short-circuit inductances in electromagnetic transients type (EMT-type) programs. Typical EMT-type tools do not provide complex FEM based computation engines for this sole purpose. The new approach is derived from the method of images and uses analytical formulations for magnetic vector potential and energy developed in this work. It is shown that the difference between the inductance calculated with the FEM in 2-D and that computed with the method of images decreases as the number of layers of images increases. Also, it is demonstrated that the classical approach, based on an axial flux distribution, can lead to considerable error if the windings have unequal heights and if they are located far from the core yokes.
Hypertrophic Burn Scar Management: What Does the Evidence Show? A Systematic Review of Randomized Controlled Trials

IntroductionHypertrophic scars (HTS) are a source of morbidity for burn survivors and can present with a range of lifestyle-limiting problems. These include pruritus, pain, burning, stiffness, and contractures. Many solutions have been developed, but few have been studied in the form of a prospective, randomized control trial (RCT). Given the importance these RCTs carry in shaping the treatment of burn patients, we sought to systematically and critically review this portion of the burn literature. MethodsPubMed was used to perform 2 separate searches with limits that included Humans, English, and Randomized Controlled Trial. A keyword search using “hypertrophic,” “Scar,” “burn,” and “treatment” was cross-referenced with a MeSH subject-heading search using “Cicatrix, Hypertrophic” AND “Burn. ” Studies were then reviewed and excluded if they did not address management of burn HTS in the non-acute setting. ResultsTwo literature searches resulted in a total of 32 articles. Twelve articles were excluded because they were not relevant to the topic (n = 10) or could not be obtained (n = 2). The remaining 20 articles contained 882 patients treated for hypertrophic scars. Breakdown based on topics included laser therapy (58 patients, 2 articles), silicone gel (204 patients, 7 articles), compression garment (236 patients, 4 articles), silicone + pressure (226 patients, 3 articles), topical emollients (58 patients, 2 articles), systemic therapy (62 patients, 1 article), intralesional therapy (18 patients, 1 article), and surgical treatment (20 patients, 1 article). While some articles had favorable conclusions (laser, emollients, surgical, and intralesional therapy) or unfavorable conclusions (systemic therapy), there were conflicting results on silicone and/or compression. ConclusionsDespite hypertrophic scars being a common occurrence in burn survivors, both the number of studies and consensus for treatment are limited. Efforts to perform larger, adequately powered RCTs are needed, specifically in the areas of silicone, compression garments, and combination therapy.
Integration of magnetoresistive sensors with atomic force microscopy cantilevers for scanning magnetoresistance microscopy applications

Various techniques of scanning magnetoresistance microscopy (SMRM) have been previously developed to enable the simultaneous imaging of surface topography and stray magnetic field distributions in order to overcome limitations of magnetic force microscopy (MFM) technique. GMR read-heads, micro-hall devices and TMR sensors integrated on piezoelectric stage have been used but lack of acceptable spatial resolution for imaging. To overcome this, magnetoresistive sensors are here integrated into standard atomic force microscopy (AFM) cantilevers and used to simultaneously map both topography and magnetic fields.
Using genetic algorithms for device modeling

In this article, genetic algorithms are used to find the optimal values for the lumped elements of a given discrete model such that its response best match the modeled device's response. By applying the method for different values of the device's parameters, the relationship between the model's and the device's parameters can be found. An application of the method to a bandpass filter shows that it can give quite precise results.
Activation of a vmp pseudogene in Borrella hermsii: an alternate mechanism of antigenic variation during relapsing fever

The relapsing fever agent, Borrella hermsii, undergoes multiphasic antigenic variation to evade its host's immune response. A frequently observed switch is serotype 7 to 26. Unlike silent vmp genes previously characterized, the transcriptionally silent vmp26 sequence was a pseudogene in lacking a start codon. In serotype 7 the location of the silent vmp26 sequence just downstream of vmp7 on the expression plasmid, as well as on the silent plasmid, was also unique. The demonstration of a predicted circular recombination product in serotype 7 but not serotype 21 populations indicates that the pseudogene was activated by an intramolecular recombination producing a deletion of DNA between 20‐nucleotide direct repeats in vmp7 and Ψvmp26.
Overcoming Resistance of Cancer Cells to PARP-1 Inhibitors with Three Different Drug Combinations

Inhibitors of poly[ADP-ribose] polymerase 1 (PARPis) show promise for treatment of cancers which lack capacity for homologous recombination repair (HRR). However, new therapeutic strategies are required in order to overcome innate and acquired resistance to these drugs and thus expand the array of cancers that could benefit from them. We show that human cancer cell lines which respond poorly to ABT-888 (a PARPi), become sensitive to it when co-treated with vorinostat (a histone deacetylase inhibitor (HDACi)). Vorinostat also sensitized PARPis insensitive cancer cell lines to 6-thioguanine (6-TG)–a drug that targets PARPis sensitive cells. The sensitizing effect of vorinostat was associated with increased phosphorylation of eukaryotic initiation factor (eIF) 2α which in and of itself increases the sensitivity of cancer cells to ABT-888. Importantly, these drug combinations did not affect survival of normal fibroblasts and breast cells, and significantly increased the inhibition of xenograft tumor growth relative to each drug alone, without affecting the mice weight or their liver and kidney function. Our results show that combination of vorinostat and ABT-888 could potentially prove useful for treatment of cancer with innate resistance to PARPis due to active HRR machinery, while the combination of vorinostat and 6-TG could potentially overcome innate or acquired resistance to PARPis due to secondary or reversal BRCA mutations, to decreased PARP-1 level or to increased expression of multiple drug resistant proteins. Importantly, drugs which increase phosphorylation of eIF2α may mimic the sensitizing effect of vorinostat on cellular response to PARPis or to 6-TG, without activating all of its downstream effectors.
Identification of typical wine aromas by means of an electronic nose

In the field of electronic noses it is not very usual to find many applications in wine detection. Most of them are related to discrimination of wines in order to prevent their illegal adulteration and detection of off-odours but their objective is not the identification of wine aromas. In this paper, an e-nose using headspace as an extraction technique is used for the identification of typical aromatic compounds present in white and red wines. The descriptors of these compounds are: fruity, floral, herbaceous, vegetative, spicy, smoky, and microbiological and they are responsible for the usual aromas in wines; concentrations differ from 2 to 10 times the threshold concentration humans can smell. Some of the measured aromas are: pear, apple, peach, coconut, rose, geranium, cut green grass, mint, vanilla, clove, almond, toast, wood and butter. Principal component analysis (PCA) shows datasets of this group of compounds are clearly separated and radial basis neural networks (RB-NN) show a 98% rate of success in classification.
An Intelligent Approach to Optimize Link State Routing Protocol in Vehicular Ad-Hoc Network

Vehicular ad-hoc network (VANET) is one of the research areas of mobile ad-hoc network (MANET) with some limitations like road constraint, speed of vehicles , location, direction of vehicle, traffic conditions structure of highways etc. and the formation of VANET takes place by moving vehicles in particular direction. The advantages of VANET are several - road side assistance, safety of drivers, spreading of information regarding any miss-happening on the road etc. Spreading the message requires communication among running vehicles. Due to vehicle speed in network the communication system failure occur most of the time, this results data delivery failure in the network. Therefore, Routing of data packet in the VANETs are more challenging task. Each vehicle in VANET has onboard unit (OBU), which provides the necessary environment for communication among vehicles and the system has routing protocols for the dissemination of message packets between the vehicles. Performance of routing algorithm depends upon the parameter selection and selection of next-hop methods for further communication with other nodes in the network. In this paper we proposes the connectivity methods and routing algorithms which draws inspiration from Swarm Intelligence to obtain different parameters to improve data dissemination. Simulation results show that our protocol will perform better than the existing solutions in terms of data dissemination under the condition of the alternating network connectivity.
Short-Term Clinical Results with an Elliptical Femoral Prosthesis

The biomechanics of an elliptical-head femoral prosthesis, considered in relation to the physiology of the coxo-femoral joint, can be taken as the rationale for its use in the treatment of medial fractures of the neck of the femur. Short-term results based on clinical variables (Harris's evaluation method) and X-ray findings show a functional joint and good preservation of radiographic relations between the prosthetic epiphysis and the acetabulum, and between the stem and femoral metadiaphysis. These findings confirm the validity of the biomechanical concepts underlying the design of the elliptical-head femoral prosthesis. It is an “etiological” solution for patients with medial fractures of the neck of the femur since it fits in with the coxo-femoral physiology without interfering with the normal anatomical/biomechanical relations between the two joint components.
Joint Radio Communication, Caching, and Computing Design for Mobile Virtual Reality Delivery in Fog Radio Access Networks

The emerging virtual reality (VR) experience demands ultra-high-transmission-rate and ultra-low-latency deliveries, which is challenging for the current cellular networks. Since fog radio access networks (F-RANs) take full advantages of both edge fog computing and caching technologies and benefit different quality-of-service requirements, it is anticipated that high-quality VR experience could be well addressed in F-RANs. This paper presents an F-RAN-based mobile VR delivery framework, in which the core idea is to cache parts of the VR videos in advance and run a certain processing procedure at the edge of F-RANs. To optimize resource allocation at both mobile VR devices and fog access points (F-APs), a joint radio communication, caching and computing decision problem is formulated to maximize the average tolerant delay with meeting a given transmission rate constraint. This problem is formulated as a multiple choice multiple dimensional knapsack problem and solved with the Lagrangian dual decomposition approach. Furthermore, the optimal joint caching and computing decision is analyzed in a specific case with a closed-form expression of the average tolerant delay. The communications-caching-computing tradeoff at both mobile VR devices and F-APs is revealed, and the numerical results demonstrate that local caching and computing capabilities have significant impacts on the average tolerant delay. The proposed mobile VR delivery framework is promising in improving spectral efficiency by maximizing average tolerant delay while meeting high transmission rate requirements.
Temporal-Spatial Nonlinear Filtering for Infrared Focal Plane Array Stripe Nonuniformity Correction

In this work, we introduce a temporal-spatial approach for infrared focal plane array (IRFPA) stripe nonuniformity correction in infrared images that generates visually appealing results. We posit that the nonuniformity appears as a striped structure in the spatial domain and that the pixel values change slowly in the temporal domain. Based on this, we formulate our correction method in two steps. In the first step, weighted guided image filtering with our adaptive weight is utilized to predict the stripe nonuniformity using a single frame. In the second step, the temporal profile of each pixel can be formed using a few frames of successive nonuniformity images. Further, we present a temporal nonlinear diffusion equation to remove scene residuals from the temporal profile of nonuniformity images in order to estimate a more accurate value of the stripe nonuniformity. The results of extensive experiments demonstrate that the proposed nonuniformity correction algorithm substantially outperforms many state-of-the-art approaches, including both traditional and deep convolution-neural-network-based methods, on four popular infrared videos. In addition, the proposed method only requires a fraction (less than ten) of the video frames.
A 9-year-old girl with persistent obsessive and compulsive behaviors in a primary care pediatric practice.

CASE Chloe is a 9-year-old gal whose mother made an initial visit to a new pediatrician for concerns about her behavior. Chloe is apprehensive about the visit and frequently hides behind her mother.Her parents first noticed Chloe becoming angry and more emotional 3 years ago, which her parents did not initially understand. However, over the past year, she has started to have more worries and unusual behavior.Chloe and her mother report that when she walks through doorways, she will almost always go back and walks through again. At home, she will walk through doorways multiple times and at school, she will pretend she forgot something so her friends do not notice. She often will not walk downstairs and occasionally her mother has to carry her. Clothes are problematic for Chloe. If her father touches something of a specific color and then touches Chloe, she will have to change her clothes or take a shower. Sometimes, she will never be able to wear those clothes again. She had a recent episode where she could not stop tapping a red paper, because if she stopped, she said it would burst into flame. During the 2 weeks before the pediatric visit, symptoms increased to the point that she is now refusing to go to school. When she stays home, she lays in 1 place all day.Chloe is a fourth grade student. The family does not report academic concerns. She has friends. She denies any appetite or sleep problems. She endorses periods of sadness, lack of energy, and decreased interest in social activities, mostly because she worries and is embarrassed. She kept her behaviors hidden from her 5 siblings for the past year, and she talked only to her mother about them. She is worried her friends might discover her behaviors.The family history is notable for multiple paternal family members with anxiety and bipolar disorder and depression on mother's side. A few months ago, Chloe's family adopted a 7-year-old child with special needs from China.Her growth, vital signs, and physical examination are unremarkable. Her mother filled out the Short Mood and Feelings Questionnaire and the Screen for Child Anxiety-Related Emotional Disorders, which both had elevated scores.
