A Simple Visual-Textual Baseline for Pedestrian Attribute Recognition

Pedestrian attribute recognition (PAR), which aims to identify attributes of the pedestrians captured in video surveillance, is a challenging task due to the poor quality of images and diverse spatial distribution among attributes. Existing methods usually model PAR as a multi-label classification problem and manually map attributes to an ordered list corresponding to the outputs of classifiers or sequential models. However, the inherent textual information among attribute annotations is largely neglected in these visual-only methods. In this paper, we first alleviate this issue by proposing a novel visual-textual baseline (VTB) for PAR which introduces an additional textual modality to explore the textual semantic correlations from attribute annotations by pre-trained textual encoders instead of human definitions. VTB encodes pedestrian images and attribute annotations into visual and textual features respectively, interacts with information across modalities, and predicts recognition results independently to remove the influence of attribute orders. Furthermore, we introduce transformer encoder as the cross-modal fusion module in VTB for sufficient intra-modal and cross-modal correlations exploration. Our method achieves superior performance over most existing visual-only methods on two widely used datasets including RAP and PA-100K, demonstrating the effectiveness of utilizing textual modality to PAR. Our method is expected to serve as a multimodal PAR baseline and inspire new insights for multimodal fusion in future PAR research. Our code is available at https://github.com/cxh0519/VTB.

The Underlying Role of the Glymphatic System and Meningeal Lymphatic Vessels in Cerebral Small Vessel Disease

There is a growing prevalence of vascular cognitive impairment (VCI) worldwide, and most research has suggested that cerebral small vessel disease (CSVD) is the main contributor to VCI. Several potential physiopathologic mechanisms have been proven to be involved in the process of CSVD, such as blood-brain barrier damage, small vessels stiffening, venous collagenosis, cerebral blood flow reduction, white matter rarefaction, chronic ischaemia, neuroinflammation, myelin damage, and subsequent neurodegeneration. However, there still is a limited overall understanding of the sequence and the relative importance of these mechanisms. The glymphatic system (GS) and meningeal lymphatic vessels (mLVs) are the analogs of the lymphatic system in the central nervous system (CNS). As such, these systems play critical roles in regulating cerebrospinal fluid (CSF) and interstitial fluid (ISF) transport, waste clearance, and, potentially, neuroinflammation. Accumulating evidence has suggested that the glymphatic and meningeal lymphatic vessels played vital roles in animal models of CSVD and patients with CSVD. Given the complexity of CSVD, it was significant to understand the underlying interaction between glymphatic and meningeal lymphatic transport with CSVD. Here, we provide a novel framework based on new advances in main four aspects, including vascular risk factors, potential mechanisms, clinical subtypes, and cognition, which aims to explain how the glymphatic system and meningeal lymphatic vessels contribute to the progression of CSVD and proposes a comprehensive insight into the novel therapeutic strategy of CSVD.
Quantitative spatiotemporal impact of dynamic population density changes on the COVID-19 pandemic in China’s mainland

ABSTRACT The coronavirus disease 2019 (COVID-19) and its mutant viruses are still wreaking global havoc over the last two years, but the impact of human activity on the transmission of the pandemic is difficult to ascertain. Estimating human dynamic spatiotemporal distribution can help in our understanding of how to mitigate COVID-19 spread, which can help in maintaining urban health within a county and between counties within a country. This distribution can be computed using the Volunteered Geographic Information (VGI) of the citizens in conjunction with other variables, such as climatic conditions, and used to analyze how human’s daily density distribution quantitatively affects COVID-19 transmission. Based on the estimated population density, when the population density increases daily by 1 person/km2 in a county or prefectural-level administrative unit with an average size of 26,000 km2, the county would have an additional 3.6 confirmed cases and 0.054 death cases after 5 days, which is the illness onset time for a new COVID-19 case. After 14 days, which is the maximum incubation period of the COVID-19 virus, there would be 5 new confirmed cases and 0.092 death cases. However, in neighboring regions, there can be 0.96 fewer people infected with COVID-19 on average per day as a result of strong intervention of local and neighboring authorities. The primary innovation and contribution are that this is the first quantitative assessment of the impacts of dynamic population density on the COVID-19 pandemic. Additionally, the direct and indirect effects of the impact are estimated using spatial panel models. The models that control the unobserved factors improve the reliability of the estimation, as validated by random experiments and the use of the Baidu migration dataset.
A histopathological study on the effects of atorvastatin against gentamicin-induced renal injury

Introduction: Gentamicin is an aminoglycoside antibiotic that is widely administered to treat infections caused by gram-negative bacteria. Gentamicin may cause renal injury in patients after seven days of administration. Atorvastatin is a cholesterol-lowering statin that acts through the mevalonate pathway. Objectives: In this study, we investigated the histopathological effects of atorvastatin against gentamicin-induced renal injury. Materials and Methods: Twenty male Wistar rats were randomly assigned into five groups and treated as the following; group 1 (normal group, no drug), group 2 [gentamicin group, daily 80 mg/kg, intra-peritoneal (i.p.) for 7 days], groups 3 to 5 (gentamicin 80 mg/kg + atorvastatin at doses of 5, 25 and 75 mg/kg, respectively). Kidney sections were examined for histopathological parameters including vacuolization of the kidney tubular cells, degeneration, necrosis, flattening of the tubular cells and debris in the tubular lumen. Results: Compared to the normal group, gentamicin significantly exacerbated the histopathological parameters. Treatment with atorvastatin significantly decreased vacuolization, degeneration, necrosis and debris in the nephrotoxic rats. Conclusion: The findings of this research indicated that atorvastatin therapy can ameliorate histopathological renal injury following gentamicin injection.
Analysis of the Equivalent Surface Current Model for the Permanent Magnet Bearing by Using the Integral Definition

The equivalent surface current is a typical method for calculating the mechanical property of permanent magnet bearing. However, Monte Carlo method or elliptic integral method are usually used to solve a quadruple integral for the equivalent surface current. However, the numerical stability is poor for the Monte Carlo method, and singular values sometimes appear for the elliptic integral method. In order to simplify the calculation, the integral definition method is proposed to solve the equations of the load capacity for the permanent magnet bearing, in details, the integral domain of integrand is divided into a infinite number of small domains, the integral value of each small domain is approximatively equal to the production of the center value of integrand and the volume of small domain, the integral value of integrand is approximatively equal to the sum of total integral value of small domains. The testing device is developed by using double layers ball screw drive systems and a 3-DOF force sensor to test the mechanical property for the permanent magnet bearing, and the results show the theoretical value of the integral definition method agrees well with the tested one. A comparative study confirms that the integral definition method is superior to the Monte Carlo method and finite element method in either the simplification of calculation process and program development or the calculation error.
Mitigation of Interturn Short Circuit Fault Based on Axial Split Phase Permanent Magnet Synchronous Machine

In order to solve the problem that three-phase PMSM cannot operate under interturn short circuit (ITSC) fault, an ITSC fault mitigation scheme based on three-phase axial split phase permanent magnet synchronous machine (ASP-PMSM) is proposed in this paper. The ASP-PMSM has inherently superior fault isolation capability among phases, high inductance and low copper loss induced by ITSC current, which greatly reduces the fault severity and difficulty of fault mitigation from machine structure. The inherently low fault severity of ASP-PMSM leaves space for postfault torque production. Therefore, it does not need the phase current to be totally injected to d-axis. As a result, the operation of three-phase PMSM under ideal ITSC fault can be realized while maintaining more than half of rated torque. In order to find out the most serious fault condition for different winding types, the influence of the number of parallel strands and the SC turn ratio on the severity of ITSC fault is investigated by theoretical analysis (TA) and finite element analysis (FEA) for the first time. And the effectiveness of the fault mitigation for the ASP-PMSM with different number of parallel strands is investigated by FEA. Finally, a three-phase prototype of ASP-PMSM is served as an example to verify the validity of analysis above. The ITSC current and temperature at different SC turn ratio and operating conditions are tested. The test results are consistent with that of TA and FEA. It is verified that the proposed fault mitigation scheme can realize the postfault operation of three-phase PMSM.

TD-Det: A Tiny Size Dense Aphid Detection Network under In-Field Environment

Simple Summary Accurate recognition and detection of pests is the basis of integrated pest management (IPM). Manual pest detection is a time-consuming and laborious work. We use computer vision technology to design an automatic aphid detection network. Compared with other methods, our model can improve the performance and efficiency of aphid detection simultaneously. Experimental results prove the effectiveness of our method. Abstract It is well recognized that aphid infestation severely reduces crop yield and further leads to significant economic loss. Therefore, accurately and efficiently detecting aphids is of vital importance in pest management. However, most existing detection methods suffer from unsatisfactory performance without fully considering the aphid characteristics, including tiny size, dense distribution, and multi-viewpoint data quality. In addition, existing clustered tiny-sized pest detection methods improve performance at the cost of time and do not meet the real-time requirements. To address the aforementioned issues, we propose a robust aphid detection method with two customized core designs: a Transformer feature pyramid network (T-FPN) and a multi-resolution training method (MTM). To be specific, the T-FPN is employed to improve the feature extraction capability by a feature-wise Transformer module (FTM) and a channel-wise feature recalibration module (CFRM), while the MTM aims at purifying the performance and lifting the efficiency simultaneously with a coarse-to-fine training pattern. To fully demonstrate the validity of our methods, abundant experiments are conducted on a densely clustered tiny pest dataset. Our method can achieve an average recall of 46.1% and an average precision of 74.2%, which outperforms other state-of-the-art methods, including ATSS, Cascade R-CNN, FCOS, FoveaBox, and CRA-Net. The efficiency comparison shows that our method can achieve the fastest training speed and obtain 0.045 s per image testing time, meeting the real-time detection. In general, our TD-Det can accurately and efficiently detect in-field aphids and lays a solid foundation for automated aphid detection and ranking.
Adaptive Communication as a Means toward better Performance : Can fit for purpose communication capability building activities help organizations in communicating to deliver strategy and to improve performance?

textabstractExecutive Summary The focus on the success factors for excellent performance has been growing in the last decades. One of the factors that is generally believed to have a positive relationship with organizational performance, is the internal communication process. Even though many practitioners and academics believe that there is a relationship between internal communication and organizational performance, there is little scientific evidence supporting this relationship. This study attempted to fill this gap in literature, by providing a definition on the concept of communication capability building and by empirically testing the existence of a relationship between communication capability building and organizational performance.
Spectrum Policy in the Age of Broadband: Issues for Congress [August 20, 2010]

This report discusses spectrum policy issues in the 111th Congress. In formulating spectrum policy, mainstream viewpoints generally diverge on whether to give priority to market economics or social goals. Among the spectrum policy initiatives that have been proposed in Congress in recent years are: allocating more spectrum for unlicensed use; auctioning airwaves currently allocated for federal use; and devising new fees on spectrum use, notably those collected by the FCC's statutory authority to implement these measures is limited.
Silicon photonic free-space beam steered optical switch using wavelength tuned nanoantennas

As optical interconnects data rates increases, the Opto–Electro–Optical (OEO) conversion in the ports of the traditional electronic packet switches (EPS) will not be an acceptable solution anymore because of lack of scalability, high cost and excess losses [9]. High speed and scalable optical switches could replace EPS and completely eliminate the need for the OEO conversion. Free–Space Optical (FSO) switches such as Micro ElectroMechanical System switches (MEMS) have high scalability but low switching speed [2]. Whereas, photonic integrated circuit (PIC) switches have shown high switching speed which ranges from some nanoseconds to 10s of microseconds but low scalability with up to 32 ports [6]. The perfect switch would combine the high scalability and high switching speed of the FSO and PIC switches, respectively. In this communication, a novel PIC switch architecture is presented to use grating couplers and their ability to diffract light to the free space. Grating couplers are facing each other and are used as transmitting and receiving nanoantennas. The switch has one input transmitting and four output receiving nanoantennas. The angle of emission of the diffracted beam depends on the wavelength which ranges from 1.3 to 1. 55μm. Tuning the wavelength, the beam is steered to one of the receiving nanoantennas. The results monitoring the nanoantennas S parameters reveal satisfactory coupling between the input and output ports with insertion losses in the range between -6 to -8dB, while the interchannel crosstalk isolation from the other ports is less than -9dB from the value of coupling.
