DSU-GAN: A robust frontal face recognition approach based on generative adversarial network

Face recognition technology is widely used in different areas, such as entrance guard, payment etc. However, little attention has been given to non-positive faces recognition, especially model training and the quality of the generated images. To this end, a novel robust frontal face recognition approach based on generative adversarial network (DSU-GAN) is proposed in this paper. A mechanism of consistency loss is presented in deformable convolution proposed in the generator-encoder to avoid additional computational overhead and the problem of overfitting. In addition, a self-attention mechanism is presented in generator–encoder to avoid information overloading and construct the long-term dependencies at the pixel level. To balance the capability between the generator and discriminator, a novelf discriminator architecture based U-Net is proposed. Finally, the single-way discriminator is improved through a new up-sampling module. Experiment results demonstrate that our proposal achieves an average Rank-1 recognition rate of 95.14% on the Multi-PIE face dataset in dealing with the multi-pose. In addition, it is proven that our proposal has achieved outstanding performance in recent benchmarks conducted on both IJB-A and IJB-C.

Energy-Efficient ReS2-Based Optoelectronic Synapse for 3D Object Reconstruction and Recognition.

The neuromorphic vision system (NVS) equipped with optoelectronic synapses integrates perception, storage, and processing and is expected to address the issues of traditional machine vision. However, owing to their lack of stereo vision, existing NVSs focus on 2D image processing, which makes it difficult to solve problems such as spatial cognition errors and low-precision interpretation. Consequently, inspired by the human visual system, an NVS with stereo vision is developed to achieve 3D object recognition, depending on the prepared ReS2 optoelectronic synapse with 12.12 fJ ultralow power consumption. This device exhibits excellent optical synaptic plasticity derived from the persistent photoconductivity effect. As the cornerstone for 3D vision, color planar information is successfully discriminated and stored in situ at the sensor end, benefiting from its wavelength-dependent plasticity in the visible region. Importantly, the dependence of the channel conductance on the target distance is experimentally revealed, implying that the structure information on the object can be directly captured and stored by the synapse. The 3D image of the object is successfully reconstructed via fusion of its planar and depth images. Therefore, the proposed 3D-NVS based on ReS2 synapses for 3D objects achieves a recognition accuracy of 97.0%, which is much higher than that for 2D objects (32.6%), demonstrating its strong ability to prevent 2D-photo spoofing in applications such as face payment, entrance guard systems, and others.

A high-performance, biocompatible, and degradable piezoresistive-triboelectric hybrid device for cross-scale human activities monitoring and self-powered smart home system

Developing wearable devices that present high-performance, human and environment-friendly, as well as excellent degradability, is crucial for personal health, environmental protection, and information security, playing a significant role in application of Internet of Things (IoT). Here, a biocompatible and degradable hybrid device (PTHD) that enables high-sensitive detection of pressure over a broad range and a remarkable self-powered capability is reported by the conjunction of the piezoresistive layer and triboelectric layer. Particularly, by dedicatedly introducing a bottom stable resistance layer, the piezoresistive layer endows the PTHD with both a high sensitivity of 281,591.8 kPa-1 and a wide response range of 0–60 kPa, which facilitates the monitoring of the cross-scale human activities ranging from tiny pulse to strenuous running. Additionally, benefiting from the excellent self-powered capability of the PTHD enabled by the triboelectric layer, a self-powered smart home system is also constructed for real-time alarming the aged falls, controlling the smart home appliances, and managing the smart entrance guard. Lastly, the PTHD is selected for culture cells and degradation experiments, proving its good biocompatibility, degradability, and potential as transient electronics.

Modeling and Performance Analysis of OAM-NFC Systems

Due to its low energy consumption and simplicity, near field communication (NFC) has been extensively used in various short-range transmission scenarios, for example, proximity payment and NFC entrance guard. However, the low data rate of NFC limits its application in high rate demanded scenarios, such as high-resolution fingerprint identification and streaming media transmission as well as the future promising high rate indoor communications among pads, phones, and laptops. In this paper, we model and analyze the performance of the orbital angular momentum based NFC (OAM-NFC) system, which can significantly increase the capacity of NFC. We first give the OAM system model. With coils circularly equipped at the transmitter and receiver, OAM-NFC signals can be transmitted, received, and detected. Then, we develop the OAM-NFC generation and detection schemes for NFC multiplexing transmission. We also analyze the OAM-NFC channel capacity and compare it with those of single-input-single-output (SISO) as well as multi-input-multi-output (MIMO) NFC. Simulation results validate the feasibility and capacity enhancement of our proposed OAM-NFC system. How different variables, such as the transceiver misalignment, the numbers of transceiver coils, and transceiver distance, impact the OAM-NFC capacity are also analyzed.

Side effects of a fungus-based biopesticide on stingless bee guarding behaviour

Pathogenic fungi have been used worldwide to control crop pests and are assumed to pose negligible threats to the survival of pollinators. Although eusocial stingless bees provide essential pollination services and might be exposed to these biopesticides in tropical agroecosystems, there is a substantial knowledge gap regarding the side effects of fungal pathogens on behavioural traits that are crucial for colony functioning, such as guarding behaviour. Here, we evaluated the effect of Beauveria bassiana on the sophisticated kin recognition system of Tetragonisca angustula, a bee with morphologically specialized entrance guards. By combining behavioural assays and chemical analyses, we show that guards detect pathogen-exposed nestmates, preventing them from accessing nests. Furthermore, cuticular profiles of pathogen-exposed foragers contained significantly lower amounts of linear alkanes than the unexposed ones. Such chemical cues associated with fungal conidia may potentially trigger aggression towards pathogen-exposed bees, preventing pathogen spread into and among colonies. This is the first demonstration that this highly abundant native bee seems to respond in a much more adaptive way to a potentially infectious threat, outweighing the costs of losing foraging workforce when reducing the chances of fungal pathogen outbreaks within their colonies, than honeybees do.

Silicone mask face anti-spoofing detection based on visual saliency and facial motion

Face recognition systems are widely used for target recognition and identity authentication, such as automated teller machines, mobile phones, and entrance guard systems. However, face recognition systems are vulnerable to presentation attacks, such as photo, replay, and 3D mask attacks. In particular, silicone mask attacks pose a greater threat to face recognition systems because high-quality silicone masks do living properties. To promote the development of face anti-spoofing detection algorithms for silicone mask attacks, this paper constructs a Silicone Mask Face Motion Video Dataset (SMFMVD) containing 200 real face videos and 200 silicone mask face videos. These videos include different facial motions collected from 20 subjects. Moreover, inspired by the observation that the silicone mask face’s facial movement is not so natural as the real face, we propose a novel silicone mask face anti-spoofing detection method based on visual saliency and facial motion characteristics. Specifically, we compute the visual saliency map of a given face image by simulating two kinds of eye movement behaviors, namely “gaze” and “saccade”. Then, we propose a saliency-weighted histogram of local binary pattern operator to extract facial texture features in spatial domain and a saliency-guided histogram of oriented optical flow operator to extract facial motion features in temporal domain. Finally, the support vector machine is used to fuse two groups of facial features to distinguish real and spoof faces. Extensive experiments on public and self-built datasets show its superiority over the state-of-the-art methods.

Current Status and Challenges of Community-Based Elderly Care Centers in Chongqing, China: A Cross-Sectional Study.

PurposeChina is facing various societal pressures owing to its rapidly aging population. In order to provide evidence-based suggestions to promote elderly care, this study investigated the community-based elderly care centres (CBECCs) in Chongqing of China, focusing on the site selections, physical environment, facilities, and operation.MethodsAll CBECCs in a district of Chongqing were analysed via a single-stage cluster sampling survey design. Descriptive statistics were used to analyse the data.ResultsA total of 69 CBECCs (60 government-run and 9 collective-run centres) were identified and analysed. Most site selections were reasonable. CBECCs that were located inside of apartment complexes with entrance guards, not located on main roads, and near a market were more popular. Only 4 (13.3%) CBECCs that were not located on the ground floor were equipped with elevators. A small number of CBECCs were near a noise pollution (10.1%) or far from a medical institution (11.6%). Nearly half (42.7%) of CBECCs only had an indoor area of <200 m2. Nearly all CBECCs had sufficient ventilation, natural lighting, and sufficient floor-to-floor height. 51.5% and 88.4% of the CBECCs fully met the criteria of ‘four rooms and one canteen’ and ‘eight functional zones’, but no significant difference was found in terms of the number of people served per month between the CBECCs that met the criteria and those that did not. A quarter of the CBECCs were operated by part-time staff. Only half provided home services (54.5%). The median of average number of people they served every month was 100 (interquartile range = 10–300).ConclusionCertain problems existed in the current CBECCs. Better elderly care especially calls for adequate elevator establishment, sufficient indoor and outdoor space, appropriate facilities and service, qualified managers and caregivers. A feasible and evidence-based plan to optimize the physical environment and facilities, functional layout and service provision is crucial to improve the CBECC service.

Age-Dependent Increase in Soldier Pheromone of the Termite Reticulitermes speratus.

Pheromone communication helps maintaining the sophisticated colony organization in social insects. In the termite Reticulitermes speratus, there are two functionally distinct soldier groups: royal guards and entrance guards. Royal guards protect kings and queens in the innermost part of the nest, whereas entrance guards prevent predators from intruding into the nest at the periphery. A recent study revealed that younger and older soldiers work as royal and entrance guards, respectively. This age-dependent distribution is thought to help workers to recognize where in the nest they are located. However, it is not known whether workers can discriminate the age of soldiers. Here, we show that the abundance of soldier pheromone changes with age and that workers discriminate a soldier's age by recognizing the pheromone abundance. Gas chromatography-mass spectrometry analysis revealed that the chemical profiles of extracts in three soldier groups of different ages (newly differentiated, royal guard, and entrance guard soldiers) are markedly different. Entrance guard soldiers have the most soldier pheromone among the three age classes. Furthermore, our bioassays suggested that the worker's movement from chamber to chamber is inhibited only when a soldier with less soldier pheromone is located at the chamber entrance. These results suggest that the soldier pheromone functions as a soldier age indicator and that workers change their behavior depending on the age of the soldier defending the chamber entrance. This study contributes to our understanding of the relationship between aging and pheromone communication in social insects.

An EEG-Based Identity Authentication System with Audiovisual Paradigm in IoT.

With the continuous increment of security risks and the limitations of traditional modes, it is necessary to design a universal and trustworthy identity authentication system for intelligent Internet of Things (IoT) applications such as an intelligent entrance guard. The characteristics of EEG (electroencephalography) have gained the confidence of researchers due to its uniqueness, stability, and universality. However, the limited usability of the experimental paradigm and the unsatisfactory classification accuracy have so far prevented the identity authentication system based on EEG to become commonplace in IoT scenarios. To address these problems, an audiovisual presentation paradigm is proposed to record the EEG signals of subjects. In the pre-processing stage, the reference electrode, ensemble averaging, and independent component analysis methods are used to remove artifacts. In the feature extraction stage, adaptive feature selection and bagging ensemble learning algorithms establish the optimal classification model. The experimental result shows that our proposal achieves the best classification accuracy when compared with other paradigms and typical EEG-based authentication methods, and the test evaluation on a login scenario is designed to further demonstrate that the proposed system is feasible, effective, and reliable.

The opacity of nursing work and configurations of risk

The article aims to reveal the invisibility of nursing work and the individual and collective strategies established to face the labor risks of attending psychiatric patients in situations of crisis. The theoretical-methodological approach combined ergonomic analysis with ergology contributions, examining in 2012 a team from an emergency unit of a Brazilian public psychiatric hospital composed of 17 nurses and two physicians (the director and medical coordinator of the unit). The results revealed that user care is strongly characterized by teamwork, especially in the confrontation of the knowledge of doctors and nurses, and is often mediated by other professionals such as social workers, administrative staff, and entrance guards. In this way, the health team extends beyond the care staff to include support services as well. It was also evidenced that this construction is effective in day-to-day work and requires skills for cooperation as well as the development of collective abilities.
