VoiceMap: Autonomous Mapping of Microphone Array for Voice Localization

Voice command systems have been widely deployed on many smart devices for remote control. To further enrich the intelligence of these smart devices, the location of sound plays an important role in context-aware acoustic services. Despite initial steps made toward reliable voice localization, the state-of-the-arts rely on prior knowledge of device location, device orientation and an indoor electronic map. To mitigate this additional cost, this article presents VoiceMap, an autonomous mapping system of acoustic devices for voice localization. The insight behind VoiceMap is to explore the cooperation of sweeping robots and voice devices. Specifically, the sweeping robot is responsible for exploring the electronic map of the environment, while the microphone array is responsible for localizing the sweeping robot, so that we can establish the positional relationship between them. The core challenges are how to accurately locate the continuously moving robot, and how to synchronize the coordinate systems of the sweeping robot and the voice devices. To this end, we first design an inertial-based super-resolution method to estimate the angle of arrival (AoA) with respect to the robot. Then, we develop an effective coordinate synchronization mechanism, so that VoiceMap can automatically locate the voice devices on the electronic map generated by the robot. Finally, we implement a prototype system using commercial devices, and conduct comprehensive experiments to verify the proposed system. The experimental results show that we can realize a median error of 0.12 m in terms of device localization.

Secretory pathways and multiple functions of nonstructural protein 1 in flavivirus infection

The genus Flavivirus contains a wide variety of viruses that cause severe disease in humans, including dengue virus, yellow fever virus, Zika virus, West Nile virus, Japanese encephalitis virus and tick-borne encephalitis virus. Nonstructural protein 1 (NS1) is a glycoprotein that encodes a 352-amino-acid polypeptide and has a molecular weight of 46–55 kDa depending on its glycosylation status. NS1 is highly conserved among multiple flaviviruses and occurs in distinct forms, including a dimeric form within the endoplasmic reticulum, a cell-associated form on the plasma membrane, or a secreted hexameric form (sNS1) trafficked to the extracellular matrix. Intracellular dimeric NS1 interacts with other NSs to participate in viral replication and virion maturation, while extracellular sNS1 plays a critical role in immune evasion, flavivirus pathogenesis and interactions with natural vectors. In this review, we provide an overview of recent research progress on flavivirus NS1, including research on the structural details, the secretory pathways in mammalian and mosquito cells and the multiple functions in viral replication, immune evasion, pathogenesis and interaction with natural hosts, drawing together the previous data to determine the properties of this protein.

The effectiveness and convergence of FRDTM is tested by means of four problems, which indicate the validity and great potential of the FRDTM for solving system of fractional partial differential equations
Comparing the host galaxies of different type supernovae

Abstract We compare the host galaxies of 902 supernovae, including Type Ia, II and Ibc, which are selected by cross-matching the Asiago Supernova Catalog with the SDSS DR7. We further selected 213 galaxies by requiring the light fraction of spectral observations > 15%, which could represent well the global properties of the galaxies. The diagrams related to D n (4000), HδA, stellar masses, SFRs and specific SFRs for the SNe hosts show that almost all SNe II and most of SNe Ibc occur in SF galaxies. A significant fraction of SNe Ia occurs in AGNs and Absorp galaxies. These results are compared with those of the 689 comparison galaxies where the SDSS fiber captures < 15% of the total light. These comparison galaxies appear biased towards higher 12+log(O/H) (~0.1dex) at a given stellar mass, suggesting the aperture effect should be kept in mind when the properties of the hosts for different types of SNe are discussed.
Public management and policing: a dialectical inquiry

ABSTRACT The study of policing offers rich opportunities to test and refine the boundaries of key concepts and theories of public management, yet it is neglected in public management discourse. In this essay, we strike up a conversation between public management and policing studies, arguing that, through this dialectical inquiry, concepts and theories in both fields can be reviewed and improved. We explore areas with particular potential for cross-fertilization: basic rationales used in public management; the saliency of state authority and legitimacy in policing; questions of public value creation (or destruction); and dilemmas of pursuing equity.
一流110 m ハードル走選手の 1 サイクル動作に関するキネマティクス的研究：疾走速度および脚長と動作の関連から

The purpose of this study was to investigate the kinematic characteristics of World and Japanese elite 110-m hurdlers during 1-cycle motion in relation to running velocity and leg length. Twenty-nine male hurdlers (SB: 12.92-14.37 s) participated. The motions from touchdown of the lead leg at the 6th hurdle (1st step) to touchdown of the takeoff leg at the 7th hurdle (4th step) were videotaped using a digital VTR camera (60 Hz), and two-dimensional coordinates were calculated based on calibration marks. The motions from touchdown of the takeoff leg at the 7th hurdle to touchdown of the lead leg at the 7th hurdle (1st step) were videotaped using two high-speed VTR cameras (200-300 Hz), and converted to two-dimensional coordinates after calculation of the three-dimensional coordinates using a DLT method. Kinematic parameters were calculated, including step length, step frequency, angles and angular velocities of the shank and thigh, and durations of the support and airborne phases. Stepwise multiple regression analysis was conducted with kinematic parameters as dependent variables, and with running velocity and leg length as independent variables at p<. 05. The results were as follows: (1) Faster hurdlers achieved a higher step frequency with less range of thigh motion of the takeoff leg during the 2nd step. (2) The 3rd step played a role in adjusting the step length and preparing for hurdling, especially in hurdlers with a shorter leg length when preparing to increase the vertical GRF in the 4th step. (3) The allocation of time from takeoff at the 4th step to touchdown at the 2nd step was dependent on leg length. (4) Faster hurdlers achieved smaller vertical displacement of CG during the 1st step by shortening the support time to keep the position of the thigh perpendicular at the 2nd step. These results show that faster hurdlers achieved shorter durations of 1-cycle motion because of the increasing in horizontal CG velocity during the shorter support time at the 2nd step.

This review thus highlights the potential of CRISPR-Cas-based genome editing in crop improvement and emphasizes the importance of continued research in this area for sustainable agricultural production.
The Role of Professionals Working with Youth: Insights and Suggestions from Urban Regeneration Zone in Ankara, Turkey

Abstract Urbanization and population growth in Turkey have worsened housing issues in Ankara’s gecekondu (squatter housing in Turkey) areas, causing more deprivation and crime. Urban regeneration aims to prevent crime, but it should prioritize human needs to prevent damage to the social fabric and psychosocial development of the youth. This phenomenological qualitative research explores the experiences, observations, expectations, and suggestions of 16 professionals working with youth in an urban generation zone in Ankara. The study found that the perception of insecurity persists, and social facilities are underutilized by the youth. The neighborhood exhibits the characteristics of a deprived area and is also affected by low socioeconomic status and poverty. Although crime has dispersed to other neighborhoods, it remains a problem in the neighborhood. A program that supports the psychosocial development of youth is necessary, as professionals find it challenging to intervene effectively and address underlying problems. Subsequent studies may examine other demographic groups and factors, including poverty, discrimination, and gender.
Official long-term and short-term strategies for preventing the spread of rumors

Recently, public security incidents caused by rumor spreading have frequently occurred, leading to public panic, social chaos and even casualties. Therefore, how governments establish strategies to restrain rumor spreading is important for judging their governance capacity. Herein, we consider one long-term strategy (education) and two short-term strategies (isolation and debunking) for officials to intervene in rumor spreading. To investigate the effects of these strategies, an improved rumor-spreading model and a series of mean-field equations are proposed. Through theoretical analysis, the effective thresholds of three rumor-prevention strategies are obtained, respectively. Finally, through simulation analysis, the effectiveness of these strategies in preventing rumor spreading is investigated. The results indicate that long-term and short-term strategies are effective in suppressing rumor spreading. The greater the efforts of governments to suppress rumors, the smaller the final rumor size. The study also shows that the three strategies are the best when applied simultaneously. The government can adopt corresponding measures to suppress rumor spreading effectively.
Dynamics of robust structures in turbulent swirling reacting flows

High-speed synchronized stereo particle-imaging velocimetry and OH planar laser-induced fluorescence (PIV/OH-PLIF) measurements are performed on multiple $R{-}\unicode[STIX]{x1D703}$ planes downstream of a high-Reynolds-number swirling jet. Dynamic-mode decomposition (DMD) – a frequency-resolved data-reduction technique – is used to identify and characterize recurrent flow structures. Illustrative results are presented in a swirling flow field for two cases – the nominal flow dynamics and where self-excited combustion driven oscillations provide strong axisymmetric narrowband forcing of the flow. The robust constituent of the nominal reacting swirl flow corresponds to a helical shear-layer disturbance at a Strouhal number ( $St$ ) of ${\sim}0.30$ , $St=fD/U_{0}$ , where $f$ , $D$ and $U_{0}$ denote the precessing vortex core (PVC) frequency ( ${\sim}800~\text{Hz}$ ), the swirler exit diameter (19 mm) and the bulk velocity at the swirler exit ( $50~\text{m}~\text{s}^{-1}$ ) respectively. Planar projections of the PVC reveal a pair of oscillating skew-symmetric regions of velocity, vorticity and OH-PLIF intensity that rotate in the same direction as the mean tangential flow. During combustion instabilities, the large-amplitude acoustics-induced axisymmetric forcing of the flow results in a fundamentally different flow response dominated by a nearly axisymmetric disturbance and almost complete suppression of the large-scale helical shear-layer disturbances dominating the nominal flow. In addition, reverse axial flows around the centreline are significantly reduced. Time traces of the robust constituent show reverse axial flows around the centreline and negative axial vorticity along the inner swirling shear layer when the planar velocity is in the same direction as the mean tangential flow. For both stable and unstable combustion, recurrent flow structures decay rapidly downstream of the air swirler, as revealed by the decreasing amplitude of the velocity, axial vorticity and OH-PLIF intensity.
Increasing use of systems science in cardiovascular disease prevention to understand how to address geographic health disparities in communities with a disproportionate burden of risk

Objective Marginalized communities shoulder a disproportionate burden of cardiovascular disease (CVD) driven by concentrated neighborhood social risk factors. We provide a case study of systems science application to address geographic CVD health disparities at the community level – informing the science of CVD health disparities research. Methods We conducted a two-phased, multi-methods needs assessment in the Denver, Colorado area. Phase I consisted of a social network analysis to map a two-mode network of existing CVD prevention interventions and their implementing organizations. In Phase II, group model building (GMB) sessions with key community, public health, and healthcare provider stakeholders, were utilized to identify and visualize community factors contributing to disparities in CVD risk, producing a consensus-based causal loop diagram. Results Between May 2021 and June 2022, we conducted 24 virtual, semi-structured interviews in Phase I to describe CVD prevention interventions, and 7 virtual GMB sessions in Phase II to describe experiences of disparities in CVD risk. For the purposes of this paper, we focus on a subset of results for both phases. In Phase I we identified 89 active CVD prevention interventions, 29 of which addressed tobacco use. In Phase II, causal loop diagrams revealed root causes of disparities in CVD risk. We provide an example of a causal loop diagram that focuses on the community prevalence of tobacco use, identifying stress as a key underlying factor driving disparities. The integration of findings from both phases highlighted the alignment and misalignment between quit tobacco intervention goals and how they are being experienced in marginalized communities. Conclusion Systems science methods were useful to organize a large number of CVD prevention efforts, and evaluate the root causes of CVD health disparities in a high risk community. By integrating these two aspects, interventions may be reoriented to more effectively address the root causes of CVD health disparities.

This article presents a <inline-formula> <tex-math notation="LaTeX">$G$ </tex-math></inline-formula>-band mode-coupler-based multimode multidrop Si dielectric waveguide (DWG) for sub-terahertz (THz)/THz interconnect. Four types of mode couplers, including <inline-formula> <tex-math notation="LaTeX">$E_{11}^{y}$ </tex-math></inline-formula>–<inline-formula> <tex-math notation="LaTeX">$E_{11}^{y}$ </tex-math></inline-formula>, <inline-formula> <tex-math notation="LaTeX">$E_{11}^{y}$ </tex-math></inline-formula>–<inline-formula> <tex-math notation="LaTeX">$E_{21}^{y}$ </tex-math></inline-formula>, <inline-formula> <tex-math notation="LaTeX">$E_{11}^{y}$ </tex-math></inline-formula>–<inline-formula> <tex-math notation="LaTeX">$E_{31}^{y}$ </tex-math></inline-formula>, and quasi-TEM to <inline-formula> <tex-math notation="LaTeX">$E_{11}^{y}$ </tex-math></inline-formula> mode couplers, are analyzed, designed, and demonstrated. The quasi-TEM to <inline-formula> <tex-math notation="LaTeX">$E_{11}^{y}$ </tex-math></inline-formula> coupler is a microstrip line (MSL)-to-DWG transition. <inline-formula> <tex-math notation="LaTeX">$E_{11}^{y}$ </tex-math></inline-formula> to <inline-formula> <tex-math notation="LaTeX">$E_{21}^{y}$ </tex-math></inline-formula> and <inline-formula> <tex-math notation="LaTeX">$E_{11}^{y}$ </tex-math></inline-formula> to <inline-formula> <tex-math notation="LaTeX">$E_{31}^{y}$ </tex-math></inline-formula> mode couplers with satisfied phase matching enable two more mode transmissions along the same waveguide. The mode-coupling theory, including the coupling coefficient, the coupling efficiency, crosstalk, and bandwidth, is studied and analyzed mathematically and guides the development of a one-side tapered coupler to boost the bandwidth. Tapered structures are employed as the smooth transition between DWG sections and mode filters to minimize the mode interference in (de)multiplexers and as the radiation terminals to reduce the reflection. The measured minimum transition loss is about 5 dB with the 3-dB bandwidth of 143–200, 151–185, and 155–174 GHz for the three modes, respectively, and the measured crosstalks between modes are less than −26 dB. A multimode multidrop sub-THz interconnect system is also demonstrated with CMOS-based transmitters (TXs)/receivers (RXs) and achieves an aggregate data rate of 65 Gb/s and the energy efficiency of 1.6 pJ/b with a bit error rate (BER) of <inline-formula> <tex-math notation="LaTeX">$10^{-12}$ </tex-math></inline-formula>.
Anti-Cytosolic 5′-Nucleotidase 1A in the Diagnosis of Patients with Suspected Idiopathic Inflammatory Myopathies: An Italian Real-Life, Single-Centre Retrospective Study

Background: Anti-cytosolic 5′-nucleotidase 1A (anti-cN1A) antibodies were proposed as a biomarker for the diagnosis of inclusion body myositis (IBM), but conflicting specificity and sensitivity evidence limits its use. Our study aimed to assess the diagnostic accuracy of anti-cN1A in a cohort of patients who underwent a myositis line immunoassay for suspected idiopathic inflammatory myopathies (IIM). We also assessed the agreement between two testing procedures: line immunoassay (LIA) and enzyme-linked immunoassay (ELISA). Materials and methods: We collected retrospective clinical and serological data for 340 patients who underwent a myositis antibody assay using LIA (EUROLINE Autoimmune Inflammatory Myopathies 16 Ag et cN-1A (IgG) line immunoassay) and verification with an anti-cN1A antibody assay using ELISA (IgG) (Euroimmun Lubeck, Germany). Results: The serum samples of 20 (5.88%) patients (15 females, 5 males, mean age 58.76 ± 18.31) tested positive for anti-cN1A using LIA, but only two out of twenty were diagnosed with IBM. Seventeen out of twenty tested positive for anti-cN1A using ELISA (median IQR, 2.9 (1.9–4.18)). Conclusions: Our study suggests excellent concordance between LIA and ELISA for detecting anti-cN1A antibodies. LIA may be a rapid and useful adjunct, and it could even replace ELISA for cN1A assay. However, the high prevalence of diseases other than IBM in our cohort of anti-cN1A-positive patients did not allow us to consider anti-cN1A antibodies as a specific biomarker for IBM.
2D numerical modeling of ultrasonic wave propagation in concrete: A parameterization study in a multiple-scattering medium

Multiple scattering is important when ultrasounds propagate in a heterogeneous medium such as concrete, the scatterer size of which is in the order of the wavelength. The aim of this work is to build a 2D numerical model of ultrasonic wave propagation integrating the multiple scattering phenomena in SPECFEM software. The coherent field of multiple scattering could be obtained by averaging numerical wave fields, and it is used to determine the effective phase velocity and attenuation corresponding to an equivalent homogeneous medium. After the creation of numerical model under several assumptions, its validation is completed in a case of scattering by one cylinder through the comparison with analytical solution. Two cases of multiple scattering by a set of cylinders at different concentrations are simulated to perform a parametric study (of frequency, scatterer concentration, scatterer size). The effective properties are compared with the predictions of Waterman-Truell model as well, to verify its validity.
Gender and job satisfaction in OECD countries

Gender differences in labour market outcomes are frequently reported. Earlier findings on associations of job satisfaction and gender reveal mixed results. Majority of empirical results indicate that women report higher levels of job satisfaction than men whereas others find no gender differences in job satisfaction. This study explores gender differences in job satisfaction by utilizing the Survey of Adult Skills for OECD countries. Employing the Balanced Worth Vector (BWV) procedure for data analysis, this study contributes to literature by presenting additional cross-national evidence from various regions of the world. Our findings reveal that there are heterogeneities in gender-gap paradox of job satisfaction across OECD countries.
Will quantum computers be the end of public key encryption?

ABSTRACT The emergence of practical quantum computers poses a significant threat to the most popular public key cryptographic schemes in current use. While we know that the well-understood algorithms for factoring large composites and solving the discrete logarithm problem run at best in superpolynomial time on conventional computers, new, less well understood algorithms run in polynomial time on certain quantum computer architectures. Many appear to be heralding this next step in computing as ‘the end of public key encryption’. We argue that this is not the case and that there are many fields of mathematics that can be used for creating ‘quantum resistant’ cryptographic schemes. We present a high-level review of the threat posed by quantum computers, using RSA and Shor’s algorithm as an example but we explain why we feel that the range of quantum algorithms that pose a threat to public key encryption schemes is likely to be limited in future. We discuss some of the other schemes that we believe could form the basis for public key encryption schemes, some of which could enter widespread use in the very near future, and indicate why some are more likely to be adopted.
