Deep Learning Based Inference of Private Information Using Embedded Sensors in Smart Devices

Smart mobile devices and mobile apps have been rolling out at swift speeds over the last decade, turning these devices into convenient and general-purpose computing platforms. Sensory data from smart devices are important resources to nourish mobile services, and they are regarded as innocuous information that can be obtained without user permissions. In this article, we show that this seemingly innocuous information could cause serious privacy issues. First, we demonstrate that users' tap positions on the screens of smart devices can be identified based on sensory data by employing some deep learning techniques. Second, it is shown that tap stream profiles for each type of apps can be collected, so that a user's app usage habit can be accurately inferred. In our experiments, the sensory data and mobile app usage information of 102 volunteers are collected. The experiment results demonstrate that the prediction accuracy of tap position inference can be at least 90 percent by utilizing convolutional neural networks. Furthermore, based on the inferred tap position information, users' app usage habits and passwords may be inferred with high accuracy.
The Effect of Growth Differentiation Factor 8 (Myostatin) on Bone Marrow–Derived Stem Cell–Coated Bioactive Sutures in a Rabbit Tendon Repair Model

Background: We have reported that bioactive sutures coated with bone marrow–derived mesenchymal stem cells (BMSCs) enhance tendon repair strength in an in vivo rat model. We have additionally shown that growth differentiation factor 8 (GDF-8, also known as myostatin) simulates tenogenesis in BMSCs in vitro. The purpose of this study was to determine the possibility of BMSC-coated bioactive sutures treated with GDF-8 to increase tendon repair strength in an in vivo rabbit tendon repair model. Methods: Rabbit BMSCs were grown and seeded on to 4-0 Ethibond sutures and treated with GDF-8. New Zealand white rabbits’ bilateral Achilles tendons were transected and randomized to experimental (BMSC-coated bioactive sutures treated with GDF-8) or plain suture repaired control groups. Tendons were harvested at 4 and 7 days after the surgery and subjected to tensile mechanical testing and quantitative polymerase chain reaction. Results: There were distinguishing differences of collagen and matrix metalloproteinase RNA level between the control and experimental groups in the early repair periods (day 4 and day 7). However, there were no significant differences between the experimental and control groups in force to 1-mm or 2-mm gap formation or stiffness at 4 or 7 days following surgery. Conclusions: BMSC-coated bioactive sutures with GDF-8 do not appear to affect in vivo rabbit tendon healing within the first week following repair despite an increased presence of quantifiable RNA level of collagen. GDF-8’s treatment efficacy of the early tendon repair remains to be defined.
Feedback regulation of Caulobacter crescentus holdfast synthesis by flagellum assembly via the holdfast inhibitor HfiA

To permanently attach to surfaces, Caulobacter crescentusproduces a strong adhesive, the holdfast. The timing of holdfast synthesis is developmentally regulated by cell cycle cues. When C. crescentusis grown in a complex medium, holdfast synthesis can also be stimulated by surface sensing, in which swarmer cells rapidly synthesize holdfast in direct response to surface contact. In contrast to growth in complex medium, here we show that when cells are grown in a defined medium, surface contact does not trigger holdfast synthesis. Moreover, we show that in a defined medium, flagellum synthesis and regulation of holdfast production are linked. In these conditions, mutants lacking a flagellum attach to surfaces over time more efficiently than either wild‐type strains or strains harboring a paralyzed flagellum. Enhanced adhesion in mutants lacking flagellar components is due to premature holdfast synthesis during the cell cycle and is regulated by the holdfast synthesis inhibitor HfiA. hfiA transcription is reduced in flagellar mutants and this reduction is modulated by the diguanylate cyclase developmental regulator PleD. We also show that, in contrast to previous predictions, flagella are not necessarily required for C. crescentus surface sensing in the absence of flow, and that arrest of flagellar rotation does not stimulate holdfast synthesis. Rather, our data support a model in which flagellum assembly feeds back to control holdfast synthesis via HfiA expression in a c‐di‐GMP‐dependent manner under defined nutrient conditions.
Charging Coordination of Plug-In Electric Vehicles in Distribution Networks With Capacity Constrained Feeder Lines

We study the charging control of plug-in electric vehicles in distribution networks with capacity constrained feeder lines. It is usually challenging to design an effective decentralized method to implement the optimal solution for the formulated constrained optimization problems due to the coupling relationship of charging behaviors on the constrained distribution network system. Alternatively, in this brief, in order to avoid possible overloading on the feeder lines, we propose a gradient projection-based decentralized method such that the step size is properly adjusted. We show that by applying the proposed method, the system converges and the implemented solution satisfies the capacity constraints of feeder lines. Simulation results show that the proposed method can effectively avoid possible overloads on the feeder lines in distribution networks.
The specificity and role of microglia in epileptogenesis in mouse models of tuberous sclerosis complex

Microglial abnormalities have been reported in pathologic specimens from patients with tuberous sclerosis complex (TSC), a genetic disorder characterized by epilepsy, intellectual disability, and autism. However, the pathogenic role of microglia in epilepsy in TSC is poorly understood, particularly whether microglia defects may be a primary contributor to epileptogenesis or are secondary to seizures or simply epiphenomena. In this study, we tested the hypothesis that Tsc1 gene inactivation in microglia is sufficient to cause epilepsy in mouse models of TSC.
Structured Robust Control Against Mixed Uncertainty

We present new approaches to designing structured controllers, which are robust in the presence of mixed real parametric and complex dynamic uncertainty. As the synthesis of such controllers is inherently NP-hard, we discuss inner and outer relaxation techniques, which make this problem amenable to computations. Our relaxation methods are positively evaluated and compared on the basis of a rich test set and for a challenging missile pilot design problem.
Differential larval responses of two ecologically similar insects (Odonata) to temperature and resource variation

How species respond to shifting environmental conditions is a central question in ecology, especially because ecosystems are experiencing rapidly changing climatic conditions. However, predicting the responses of species interactions and community composition to changing conditions is often difficult. We examined the effects of rearing temperature and resource level on larval survival of two ecologically similar dragonflies, Erythemis collocata and Pachydiplax longipennis. Within high and low (26 and 21°C) temperatures, we crossed species and resource level and reared larvae individually. We predicted that warmer temperatures would reduce survival and increase growth rate, that higher resource availability would increase survival and growth rate, and that the two species would respond similarly. We found that increased temperature reduced survival for both species. There was also an interaction between temperature and species: E. collocata had higher survival at the lower temperature, but lower survival at the higher temperature when compared to P. longipennis. Resource level did not affect survival. In general, P. longipennis grew more than E. collocata, with no effects of temperature or resource level. These results suggest that these species respond dissimilarly to changing thermal conditions, that increased food availability cannot always compensate for the negative effects of higher temperatures, and that climate change may affect interactions between these two sympatric, ecologically similar species, with potential consequences for community composition.
An Image Encryption Method Based on the Feistel Network and Dynamic DNA Encoding

Based on the Feistel network and dynamic deoxyribonucleic acid (DNA) encoding technology, an image encryption method is proposed using the “permutation–diffusion–scrambling” structure. First, the SHA-3 algorithm is used to calculate the hash value of the plaintext image as the initial value of the hyperchaotic system, and the chaos-generated sequence is used to generate the Hill cipher matrix to replace the image pixel. Second, the DNA sequence operation is used as the F function of the Feistel network. The DNA sequence database is used as the key K of Feistel network, and the image pixel value diffusion is realized by the Feistel network. Finally, further diffusion is carried out through the ciphertext feedback and through the ciphertext confusion and diffusion of three rounds of “chaotic scrambling-DNA encoding-Feistel transformation-DNA decoding,” making the ciphertext more random and resistant to attacks and ensuring that the encrypted ciphertext is more secure. The experimental results show that the proposed method can effectively encrypt the image and has prominent characteristics, such as strong plaintext sensitivity, a large key space, and excellent ciphertext statistical properties.
Decomposing early and adult life social position effects on oral health and chronic diseases in a cross‐sectional study of Southern Brazil

OBJECTIVES As the socio-economic trajectory can influence on individual health during the life course, the aim of this study was to test a model of socio-economic life course effects on chronic diseases, tooth loss and on oral health-related quality of life using structural equation model (SEM) to decompose direct and indirect effects. METHODS This cross-sectional study was performed in southern Brazil, within public healthcare users with 18 years old or more (n = 433). Latent variables were the Oral Health Impact Profile (OHIP), Childhood Socio-economic Status (SESC) and Adulthood (SESA), and Chronic Diseases (CD), and observed variables were sex, age, smoking status and tooth loss. The statistical analysis was performed using structural equation modelling (SEM) using WLSMV estimator. For the final model, we kept only plausible significant paths with P < 0.30. RESULTS Final model presented an adequate fit: RMSA 0.03, Comparative Fit Index (CFI) 0.97, TLI 0.97, and Weighted Root Mean Square Residual (WRMR) 1.19. The direct effect from SESC to tooth loss was β = -0.08 (P = 0.19) and the indirect was β = -0.12 (P = 0.02). The indirect effect from SESC to OHIP was β = -0.14 (P = 0.01) and there is no direct effect. The direct effect from SESA to tooth loss was β = -0.21 (P < 0.01) and there is no indirect effect. The direct effect from SESA to OHIP was β = -0.14 (P = 0.05). The association of SESA on SESC was β = 0.59 (P < 0.01). CONCLUSIONS SESC had indirect effects on OHIP and number of teeth via SESA, supporting the chain of effects theory, but not for chronic diseases.
Activation of TRPV1 Prevents Salt-Induced Kidney Damage and Hypertension After Renal Ischemia-Reperfusion Injury in Rats

Background/Aims: High-salt intake after recovery from renal ischemia-reperfusion (I/R) injury leads to hypertension with severe renal damage. Transient receptor potential vanilloid type 1 (TRPV1) channels have been involved in the regulation of inflammation and oxidative stress following ischemic organ injury. We tested the hypothesis that activation of TRPV1 conveys preconditioning protection to the kidney subjected to I/R. Methods: TRPV1 was activated or down-regulated by subcutaneous injection of a low (1mg/kg) or high (100mg/kg) dose of capsaicin, respectively, 3 hours before ischemia. Rats were fed a 0.4% NaCl diet for 5 weeks after I/R followed by a 4% NaCl diet for 4 more weeks in 4 groups: sham, I/R, I/R+high-dose capsaicin (HCap), and I/R+low-dose capsaicin (LCap). Results: Renal TRPV1 expression was decreased in I/R rats (P< 0.05) and further reduced in I/R+HCap group (P< 0.05) but unchanged in I/R+LCap rats compared with the sham group. Blood pressure were elevated in I/R rats (P< 0.05) and further increased in I/R+HCap group (P< 0.05) but unchanged in I/R+LCap rats compared with sham. Renal function was impaired in I/R rats (P< 0.05) and further deteriorated in I/R+HCap group (P< 0.05) but unchanged in I/R+LCap group. Renal inflammatory responses, oxidative stress, and renal collagen deposition were augmented in I/R rats (all P< 0.05) and further intensified in I/R+HCap group (all P< 0.05) but unchanged in I/R+LCap group. Conclusion: Activation of TRPV1 plays an anti-inflammatory and anti-oxidative stress role in preventing renal tissue damage and salt-induced hypertension after I/R injury, indicating that TRPV1 conveys preconditioning protection that may have therapeutic implication.
Knowledge, awareness and acceptability of anti-HPV vaccine in the Arab states of the Middle East and North Africa Region: a systematic review.

Background Rapid changes in lifestyle induced by globalization have brought about changes in sexual behaviour, especially among younger generations. These changes may lead to considerable consequences on the prevalence of sexually transmitted disease, including human papillomavirus (HPV) infection. Aims The objective of this study is to provide a systematic review of peer-reviewed literature on human papillomavirus (HPV) vaccine awareness and acceptability in the Arab states of the Middle East and North Africa region. Methods A systematic search was conducted across 2 electronic databases: PubMed and EMBASE, to identify studies related to HPV vaccination awareness and acceptability in the region between January 2010 and April 2017. Results Eighteen studies from 9 countries were identified. The analysis showed low to moderate HPV infection knowledge and anti-HPV vaccine awareness. Nevertheless, most studies reported moderate to high anti-HPV vaccine acceptability among subpopulations. Broad gaps in knowledge and willingness were highlighted regarding HPV vaccine acceptability. Conclusions An examination of the region collectively offers an insight into the willingness of the general population and healthcare providers to receive more information about the virus and prevention of infection through vaccination. This review suggests that the vaccine acceptability would be high once cost concerns are resolved.
Bandwidth and Gain Enhancement of Ridge Gap Waveguide H-Plane Horn Antennas Using Outer Transitions

In this communication, solutions are developed for gain and bandwidth enhancement of a ridge gap waveguide (RGW) H-plane horn antenna. Intrinsic features of RGW allow us to introduce a simple transition at the antenna aperture making its impedance matching with outer space easier, leading to antenna bandwidth enhancement. Two transitions, stepped and tapered, are introduced. The proposed transitions are fully designed as a part of horn flared part and do not introduce any expansion to the antenna length, contributing to its compactness. Furthermore, the modified form of the proposed RGW H-plane horn in which the antenna aperture is squinted is also presented. In this form, the backward radiation is reduced leading to 2 dB gain enhancement.
Amorphous Calcium Carbonate Granules Form Within an Intracellular Compartment in Calcifying Cyanobacteria

The recent discovery of cyanobacteria forming intracellular amorphous calcium carbonate (ACC) has challenged the former paradigm suggesting that cyanobacteria-mediated carbonatogenesis was exclusively extracellular. Yet, the mechanisms of intracellular biomineralization in cyanobacteria and in particular whether this takes place within an intracellular microcompartment, remain poorly understood. Here, we analyzed six cyanobacterial strains forming intracellular ACC by transmission electron microscopy. We tested two different approaches to preserve as well as possible the intracellular ACC inclusions: (i) freeze-substitution followed by epoxy embedding and room-temperature ultramicrotomy and (ii) high-pressure freezing followed by cryo-ultramicrotomy, usually referred to as cryo-electron microscopy of vitreous sections (CEMOVIS). We observed that the first method preserved ACC well in 500-nm-thick sections but not in 70-nm-thick sections. However, cell ultrastructures were difficult to clearly observe in the 500-nm-thick sections. In contrast, CEMOVIS provided a high preservation quality of bacterial ultrastructures, including the intracellular ACC inclusions in 50-nm-thick sections. ACC inclusions displayed different textures, suggesting varying brittleness, possibly resulting from different hydration levels. Moreover, an electron dense envelope of ∼2.5 nm was systematically observed around ACC granules in all studied cyanobacterial strains. This envelope may be composed of a protein shell or a lipid monolayer, but not a lipid bilayer as usually observed in other bacteria forming intracellular minerals. Overall, this study evidenced that ACC inclusions formed and were stabilized within a previously unidentified bacterial microcompartment in some species of cyanobacteria.
Investigation on silent bacterial infections in specimens from pregnant women affected by spontaneous miscarriage

Miscarriage is one of the main complications occurring in pregnancy. The association between adverse pregnancy outcomes and silent bacterial infections has been poorly investigated. Ureaplasma parvum and urealiticum, Mycoplasma genitalium and hominis and Chlamydia trachomatis DNA sequences have been investigated by polymerase chain reaction (PCR) methods in chorionic villi tissues and peripheral blood mononuclear cells (PBMCs) from females with spontaneous abortion (SA, n = 100) and females who underwent voluntary interruption of pregnancy (VI, n = 100). U. parvum DNA was detected in 14% and 15% of SA and VI, respectively, with a mean of bacterial DNA load of 1.3 × 10−1 copy/cell in SA and 2.8 × 10 −3 copy/cell in VI; U. urealiticum DNA was detected in 3% and 2% of SA and VI specimens, respectively, with a mean DNA load of 3.3 × 10−3 copy/cell in SA and 1.6 × 10−3 copy/cell in VI; M. hominis DNA was detected in 5% of SA specimens with a DNA load of 1.3 × 10−4 copy/cell and in 6% of VI specimens with a DNA load of 1.4 × 10−4 copy/cell; C. trachomatis DNA was detected in 3% of SA specimens with a DNA load of 1.5 × 10−4 copy/cell and in 4% of VI specimens with a mean DNA load of 1.4 × 10−4 copy/cell. In PBMCs from the SA and VI groups, Ureaplasma spp, Mycoplasma spp and C. trachomatis DNAs were detected with a prevalence of 1%–3%. Bacteria were investigated, for the first time, by quantitative real‐time PCR (qPCR) in chorionic villi tissues and PBMCs from women affected by SA and VI. These data may help to understand the role and our knowledge of the silent infections in SA.
Substrate Integrated Waveguide-Based Periodic Backward-to-Forward Scanning Leaky-Wave Antenna With Low Cross-Polarization

For many leaky-wave antennas (LWAs), it is challenging to realize beam scanning through broadside. A problem is the presence of an open stopband (OSB), which restricts radiation in the broadside direction. In this paper, a novel substrate integrated waveguide (SIW)-based LWA is described to overcome the OSB problem and provide beam scanning continuously from the backward to the forward direction from a conventional periodic LWA. It is demonstrated that the $n =-1$ spatial harmonic can be excited efficiently from an SIW LWA and enables broadside radiation. However, it was found in our initial design that when the beam scans through the broadside, the cross-polarization level increases significantly compared to the beam close to the backfire direction. A technique is developed to reduce the cross-polarization level. As a result, a new antenna configuration is created. The antenna design has been realized and measured to validate the concept. The measured beam scanning range of the prototype is from −74° to +45° (119° of beam scanning) when the frequency sweeps from 7.625 to 11 GHz, and the measured cross-polarization level is 20.8 dB low at the main beam direction for the broadside beam.
Cross-Layer Resource Allocation Using Video Slice Header Information for Wireless Transmission Over LTE

In this paper, cross-layer resource allocation methods for wireless video transmission are proposed. We propose two practical metrics to measure the relative importance of each forward error correction (FEC) block to the user’s quality of experience. They can be obtained from the header information, and require no overhead bits or amendment of the header format of the existing standard video codec. We discuss adaptive modulation and coding scheme allocation, and adaptive energy allocation for the FEC blocks of a group of pictures. We also provide low-complexity resource allocation solutions. In both approaches, we consider two types of slice packetization, which affect the priority of FEC blocks. The proposed cross-layer resource allocation methods have significant performance gain over equal error protection, and similar performance to more complicated algorithms.
Agreement Between Parent Proxy Reports and Self-Reports of Adolescent Emotional Distress

Parents’ recognition of adolescents’ emotional distress is a significant determinant of early detection and treatment of mental disorders. However, there is dearth of research exploring parent–adolescent agreement regarding adolescents’ emotional distress. This cross-sectional, school-based study compared parents’ proxy reports and self-reports of adolescent’s emotional distress among 289 parent–adolescent dyads in Korea. Findings revealed low agreement between adolescents’ and parents’ reports of depression, anxiety, and anger, with an average polychoric r of . 25 to . 27. The agreement was particularly low for high school students, boys, and father–adolescent dyads. Additionally, parents tended to underestimate adolescents’ emotional distress symptoms; a significant percentage of adolescents experiencing symptoms were rated in the normal range by parents, particularly high school students experiencing anger. Interventions are needed to help adolescents learn to manage and express their negative emotions. Moreover, parent education programs that improve parents’ recognition of emotional distress and appropriate help-seeking behaviors are needed.
