The association between discrimination and PTSD in African Americans: exploring the role of gender

ABSTRACT Background: Research has demonstrated the adverse impact that discrimination has on physical and mental health. However, few studies have examined the association between discrimination and symptoms of posttraumatic stress disorder (PTSD). There is evidence that African Americans experience higher rates of PTSD and are more likely to develop PTSD following trauma exposure than Whites, and discrimination may be one reason for this disparity. Purpose: To examine the association between discrimination and PTSD among a cross-sectional sample largely comprising African American women, controlling for other psychosocial stressors (psychological distress, neighborhood safety, crime). Methods: A sample of 806 participants was recruited from two low-income predominantly African American neighborhoods. Participants completed self-report measures of PTSD symptoms, perceived discrimination, perceived safety, and psychological distress. Information on neighborhood crime was obtained through data requested from the city. Multivariate linear regression models were estimated to assess adjusted relationships between PTSD symptoms and discrimination. Results: Discrimination was significantly associated with PTSD symptoms with a small effect size, controlling for relevant sociodemographic variables. This association remained consistent after controlling for psychological distress, perceived safety, and total neighborhood crime. There was no evidence of a gender by discrimination interaction. Participants who experienced any discrimination were significantly more likely to screen positive for PTSD. Conclusions: Discrimination may contribute to the disparate rates of PTSD experienced by African Americans. PTSD is associated with a range of negative consequences, including poorer physical health, mental health, and quality of life. These results suggest the importance of finding ways to promote resilience in this at-risk population.

Conclusions arising from the comparison of the measured field values with relevant reference levels in force for safe general public and occupational exposure as well as with the results of previous research are finally given.
An amplifier‐offset‐insensitive and high PSRR subthreshold CMOS voltage reference

An amplifier‐offset‐insensitive complementary metal‐oxide‐semiconductor (MOS) voltage reference (CVR) circuit with high power supply ripple rejection (PSRR) is presented. Due to the novel structure of employing subthreshold MOS transistors, the proposed CVR circuit can suppress the direct current offset effects of the internal amplifier. Design considerations in optimizing the power and area consumptions and improving the PSRR are presented. The proposed CVR circuit is implemented in a standard 0.18 μm complementary MOS process. Measured results show that the reference can run with down‐to 0.9 V supply voltage, while the power consumption is only 70 nW. The measured PSRR is better than −37 dB over the full frequency range.
An Embedded Multi-Sensor Data Fusion Design for Vehicle Perception Tasks

 —Nowadays, multi-sensor architectures are popular to provide a better understanding of environment perception for intelligent vehicles. Using multiple sensors to deal with perception tasks in a rich environment is a natural solution. Most of the research works have focused on PC-based implementations for perception tasks and very few concerns have been addressed for customized embedded designs. In this paper, we propose a Multi-Sensor Data Fusion (MSDF) embedded design for vehicle perception tasks using stereo camera and Light Detection and Ranging (LIDAR) sensors. A modular and scalable architecture based on Zynq-7000 SoC was designed.
Irradiation cross-linking of ethylene vinyl acetate/waste tire dust

In an attempt to maximize the beneficial effect of irradiation, the influence of multifunctional acrylates (MFAs) such as trimethylol propane triacrylate, ethylene glycol dimethacrylate, trimethylol propane trimethacrylate, and tripropylene glycol diacrylate on the 90/10 ethylene vinyl acetate/waste tire dust (EVA/WTD) were studied. The 90/10 EVA/WTD and EVA-containing 4 phr MFA prepared using a Haake mixer at 140°C and 50 r min−1 rotor speed. The blends were then irradiated using a 3.0-MeV electron beam machine. Results on gel fraction revealed that EVA/WTD blends were cross-linked by electron beam irradiation. Among the MFA employed in this studies, TPGDA was found to render highest tensile strength with the best retention in elongation at break and increased heat of fusion and crystallinity of blends upon irradiation. The changes in the properties of EVA/WTD blends upon irradiation are attributed to the cross-linking of the EVA matrix. The changes in crystallinity and crystalline melting temperatures of EVA/WTD blends upon irradiation are discussed in detail.
Data Center Diagnostics with Network Provenance

Diagnosing problems in data centers has always been a challenging problem due to their complexity and heterogeneity. Among recent proposals for addressing this challenge, one promising approach leverages provenance , which provides the fundamental functionality that is needed for performing fault diagnosis and debugging—a way to track direct and indirect causal relationships between system states and their changes. This information is valuable, since it permits system operators to tie observed symptoms of a faults to their potential root causes. However, capturing provenance in a data center is challenging because, at high data rates, it would impose a substantial cost. In this paper, we introduce techniques that can help with this: We show how to reduce the cost of maintaining provenance by leveraging structural similarities for compression, and by ofﬂoading expensive but highly parallel operations to hardware. We also discuss our progress towards transforming provenance into compact actionable diagnostic decisions to repair problems caused by misconﬁgurations and program bugs.
Recent developments of artificial intelligence in drying of fresh food: A review

ABSTRACT Intellectualization is an important direction of drying development and artificial intelligence (AI) technologies have been widely used to solve problems of nonlinear function approximation, pattern detection, data interpretation, optimization, simulation, diagnosis, control, data sorting, clustering, and noise reduction in different food drying technologies due to the advantages of self-learning ability, adaptive ability, strong fault tolerance and high degree robustness to map the nonlinear structures of arbitrarily complex and dynamic phenomena. This article presents a comprehensive review on intelligent drying technologies and their applications. The paper starts with the introduction of basic theoretical knowledge of ANN, fuzzy logic and expert system. Then, we summarize the AI application of modeling, predicting, and optimization of heat and mass transfer, thermodynamic performance parameters, and quality indicators as well as physiochemical properties of dried products in artificial biomimetic technology (electronic nose, computer vision) and different conventional drying technologies. Furthermore, opportunities and limitations of AI technique in drying are also outlined to provide more ideas for researchers in this area.
Disseminated Primary Cutaneous CD8+ Small/Medium-sized Pleomorphic T-cell Lymphoma Responding to Hydroxychloroquine.

Primary cutaneous CD8+ small/medium-sized pleomorphic T-cell lymphoma (CD8+ SMPTL) is a rare entity with most probably indolent clinical behaviour. Several cases with facial localisation, mostly localised to the ear, have previously been described (1). Reports of extrafacial involvement are limited, and mostly involve acral sites such as the hands and feet. The classification concerning this rare cutaneous lymphoma remains to be defined. To date, no treatment modalities have been systematically evaluated.
Atrial fibrillation and venous thromboembolism: evidence of bidirectionality in the Atherosclerosis Risk in Communities Study

Essentials Atrial fibrillation (AF) may increase risk of venous thromboembolism (VTE), and vice versa. Bidirectionality was assessed prospectively via data from 15 129 black and white individuals. AF was associated with greater risk of developing VTE, and VTE with greater risk of AF. Associations were strongest among blacks and in the first 6 months after initial diagnosis.
Research on Air Flow Measurement and Optimization of Control Algorithm in Air Disinfection System

Abstract As the air flow control system has the characteristics of delay and uncertainty, this research designed and achieved a practical air flow control system by using the hydrodynamic theory and the modern control theory. Firstly, the mathematical model of the air flow distribution of the system is analyzed from the hydrodynamics perspective. Then the model of the system is transformed into a lumped parameter state space expression by using the Galerkin method. Finally, the air flow is distributed more evenly through the estimation of the system state and optimal control. The simulation results show that this algorithm has good robustness and anti-interference ability
CosDic: Towards a Comprehensive System for Knowledge Discovery in Large-Scale Data: Architecture, Implementation and Case Studies

The continued exponential growth in both the volume and the complexity of information is giving birth to a new challenge to the specific requirements of analysts, researchers and intelligence providers. In this paper, to move the scientific activity forward to practice, we elaborate a prototype of our on-going constructed system, CosDic, for knowledge discovery from extremely large-scale datasets. The major infrastructure of CosDic is deployed on a distributed cluster environment using MapReduce platform. To undertake the mining tasks from gigabytes to petabytes, we carefully devised our system, from architecture to particular algorithms, from under layer construction to upper layer public service interface, from effectiveness to efficiency. Moreover, to illustrate its functionality, we employ CosDic to a real-world huge dataset and demonstrate an integrated analysis procedure from initial raw data preprocessing to finally knowledge discovering. We show that CosDic has a good performance in such cloud-scale data computing.
Effects of feeding Fusarium fujikuroi culture material, containing known levels of moniliformin, in young broiler chicks.

An experiment was conducted with 270 male broiler chicks to evaluate the effects of a Fusarium fujikuroi M-1214 culture material containing moniliformin (M) on broiler chicks. Day-old chicks were allotted randomly to dietary treatments containing 0, . 24, . 48, . 72, . 96, 1.44, 1.92, 2.40, and 2.88% M culture material (MCM). These levels of MCM supplied 0, 25, 50, 75, 100, 150, 200, 250, or 300 mg M/kg of feed. Each dietary treatment was fed to six pen replicates of five chicks per pen for 21 d. Significant mortality (P < .05) occurred in chicks fed 200 (8 out of 30), 250 (17 out of 30), and 300 (25 out of 30) mg M/kg feed. Chicks fed > 100 mg M/kg had lower (P < .05) feed intakes and smaller BW gains (P < .05) than controls. Increased heart weights (P < .05) were observed in chicks fed > 50 mg M/kg, and increased liver weights (P < .05) in chicks fed > 100 mg M/kg. Gross lesions of M toxicity included generalized cardiomegaly with dilation of the right ventricle. Histopathology revealed a high incidence of large and variably shaped cardiomyocyte nuclei and a generalized loss of cardiomyocyte cross striations in chicks fed > 75 and 200 mg M/kg, respectively. Results indicated that F. fujikuroi culture material containing M is toxic to young broiler chicks.
Classification of Human Milks Based on Their Trans 18:1 Fatty Acid Profile and Effect of Maternal Diet.

BACKGROUND The diet of breastfeeding women influences the trans fatty acid (TFA) composition of the milk excreted. However, the effects associated to TFA are isomer-dependent and diverse TFA profiles may have different nutritional implications. OBJECTIVE The aim of this research was to evaluate whether certain TFA patterns in human milk fat can be used as indicators of TFA intake from different sources. METHODS Milk fat from 60 women were examined and classified based on their TFA profile and conjugated linoleic acid (CLA) contents by principal component analysis (PCA). RESULTS The PCA of the data allowed the classification of the women into 3 groups depending on milk TFA content and profile. From the 60 subjects, 19 presented a TFA profile characteristic of ruminant products intake, 10 a typical TFA profile of industrial trans fats consumption and 31 a negligible trans content. Superimposed on this, 21 women presented high amounts of docosahexaenoic acid (22:6 n-3) which was related to fish intake. CONCLUSIONS The present research overcome problems associated to heterogeneous groups in nutritional experiments by a statistical classification of lactating subjects based on the TFA composition of their milk. This classification could be extrapolated to other nutritional studies dealing with TFA analysis and samples of different nature as biological samples or foodstuffs.
Exploiting a search engine to develop more flexible Web agents

With the rapid growth of the World Wide Web, more and more people rely on the online services to acquire and integrate information. However, it is time consuming to find the online services that are perfectly suited for a given task. First, the users might not have enough information to fill in the required input fields for querying an online service. Second, the online service might generate only partial information. Third, the user might only find the inverse version of the desired service. We propose a framework to develop flexible Web agents that handle these imperfect situations. In this framework we exploit a search engine as a general information discovery tool to assist finding and pruning information. To demonstrate this framework, we implemented two Web agents: the Internet inverse geocoder and the address lookup module.
Toward Scalable Social Alt Text: Conversational Crowdsourcing as a Tool for Refining Vision-to-Language Technology for the Blind

The access of visually impaired users to imagery in social media is constrained by the availability of suitable alt text. It is unknown how imperfections in emerging tools for automatic caption generation may help or hinder blind users' understanding of social media posts with embedded imagery. In this paper, we study how crowdsourcing can be used both for evaluating the value provided by existing automated approaches and for enabling workflows that provide scalable and useful alt text to blind users. Using real-time crowdsourcing, we designed experiences that varied the depth of interaction of the crowd in assisting visually impaired users at caption interpretation, and measured trade-offs in effectiveness, scalability, and reusability. We show that the shortcomings of existing AI image captioning systems frequently hinder a user's understanding of an image they cannot see to a degree that even clarifying conversations with sighted assistants cannot correct. Our detailed analysis of the set of clarifying conversations collected from our studies led to the design of experiences that can effectively assist users in a scalable way without the need for real-time interaction. They also provide lessons and guidelines that human captioners and the designers of future iterations of AI captioning systems can use to improve labeling of social media imagery for blind users.
Analysis of localization cue preservation by multichannel wiener filtering based binaural noise reduction in hearing aids

In this paper the localization cue preservation of a noise reduction algorithm for binaural hearing aids is analyzed. In a binaural noise reduction procedure based on Multi-channel Wiener Filtering (MWF), the basic cost function is extended with terms related to the Interaural Transfer Functions (ITF) of a speech and noise source. To make the algorithm computationally feasible, these cost terms are simplified to quadratic terms. First it is shown that this approach cannot preserve the ITF of the speech and noise component simultaneously. However, the obtained output ITF is related to the output SNR. This will lead to a perceptually advantageous effect: a noisy output signal (low SNR) will be perceived in the direction of the noise source, while a clean output signal (high SNR) will be perceived in the direction of the speech source.
A constrained joint source/channel coder design

The design of joint source/channel coders in situations where there is residual redundancy at the output of the source coder is examined. It has previously been shown that this residual redundancy can be used to provide error protection without a channel coder. In this paper, this approach is extended to conventional source coder/convolutional coder combinations. A family of nonbinary encoders is developed which more efficiently use the residual redundancy in the source coder output. It is shown through simulation results that the proposed systems outperform conventional source-channel coder pairs with gains of greater than 9 dB in the reconstruction SNR at high probability of error. >
Effect of route of inoculation on humoral immune response of White Leghorn chickens selected for high or low antibody response to sheep red blood cells.

Effects of route of SRBC inoculation and antigen dosage on primary and secondary antibody response of White Leghorn lines selected for high (HA) or low (LA) 5-d antibody response to a single i.v. inoculation with 0.1 mL of a 0.25% suspension of SRBC were studied in two trials. In the first trial, chicks from parents of generation S24 of each line were randomly assigned to one of four treatments. At 35 d of age, they were inoculated into the brachial vein with 0.1 mL of 0.25% suspension of SRBC or into the breast muscle with 0.1 mL of 0.25, 2.50, or 25.00% SRBC. Plasma SRBC antibody was measured 3, 6, 10, and 20 d later. In the second trial, chicks from parents of generation S25 of each line were randomly assigned to treatment groups. At 28 d of age they were inoculated with 0.1 mL of 0.25% SRBC into the brachial vein, 0.1 mL of 25.00% SRBC into the thigh (T-L) or breast muscle (B-L), or 0.5 mL of 25.00% SRBC into the thigh (T-H) or breast muscle (B-H). Twenty-one days later, chicks (except five per group) were given a booster inoculation of 0.1 mL of 25.00% SRBC into the thigh muscle. Six and 10 d after each inoculation, plasma SRBC antibody, IgG, and IgM titers were measured. The SRBC antibody titers after primary i.v. inoculation with SRBC were always higher for HA than LA chicks. When inoculations were i.m. , differences between lines varied with dosage. Low dosages inoculated into the breast failed to induce line differences consistently, whereas at higher dosages, titers were greater for HA than LA chicks regardless of inoculation site. For Line LA, inoculation into the thigh elicited higher titers than inoculations into the breast. Antibody titers to the booster inoculation of SRBC were similar for the lines.
Vaginal film for prevention of HIV: using visual and tactile evaluations among potential users to inform product design

Abstract Topical prevention of HIV and other STIs is a global health priority. To provide options for users, developers have worked to design safe, effective and acceptable vaginal dissolving film formulations. We aimed to characterize user experiences of vaginal film size, texture and color, and their role in product-elicited sensory perceptions (i.e. perceptibility), acceptability and willingness to use. In the context of a user-centered product evaluation study, we elicited users’ ‘first impressions’ of various vaginal film formulation designs via visual and tactile prototype inspection during a qualitative user evaluation interview. Twenty-four women evaluated prototypes. Participants considered size and texture to be important for easy insertion. Color was more important following dissolution than prior to insertion. When asked to combine and balance all properties to arrive at an ideal film, previously stated priorities for individual characteristics sometimes shifted, with the salience of some individual characteristics lessening when multiple characteristics were weighted in combination. While first impressions alone may not drive product uptake, users’ willingness to initially try a product is likely impacted by such impressions. Developers should consider potential users’ experiences and preferences in vaginal film design. This user-focused approach is useful for characterizing user sensory perceptions and experiences relevant to early design of prevention technologies.
Insights into the epidemic characteristics and evolutionary history of the novel porcine circovirus type 3 in southern China.

Porcine circovirus type 3 (PCV3) is a newly identified circovirus from swine in the USA, China and Poland. This novel circovirus has been associated with porcine dermatitis and nephropathy syndrome (PDNS), reproductive failure and multisystemic inflammation; moreover, PCV3 poses a potential threat to the swine industry. In this retrospective study, a phylogenetic analysis was conducted to address the epidemiology and evolutionary dynamics of this novel circovirus. The total positive sample rate of PCV3 was 26.7% (76/285) and has increased gradually over the past 3 years. Of these PCV3-positive samples, 22.3% (17/76) were coinfected with PCV2. PCV3 can be detected in multiple sample types with different positive rates, and the positive rate is highest among stillborn. We also divide PCV3 into three clades (PCV3a, PCV3b and PCV3c) based on two amino acid mutations (A24V and R27K) on the cap protein in this study. In addition, the origin of PCV3 was approximately 1966 and may have originated from a bat-associated circovirus. Our results suggested that PCV3 is widely distributed in southern China and has been circulating in swine herds for nearly half a century. PCV3 has evolved into different clades caused by mutations in cap proteins; thus, further research on PCV3 epidemiology should be conducted.
