Design and power-assistance analysis of a bending-over exoskeleton robot

The stooping and handling exoskeleton robot integrating multi-field technologies such as mechatronics, human-computer interaction, gait analysis and intelligence is an important development direction in the field of robot research and development in recent years. The boosting efficiency is the most critical evaluation index in the overall performance of the exoskeleton robot. In this paper, by analyzing the changes of the human lumbar spine force in the state of normal bending and carrying under the state of natural motion cycle, the state of wearing the exoskeleton without assistance, and the state of wearing exoskeleton assistance, this paper establishes a bending and carrying model, completes the force analysis, and deduces the power-assisting efficiency. Compare the calculation formula, and design a wearable stooping exoskeleton robot based on this, and conduct EMG experiment data in three states to collect the changes of the user's biomechanical signals. The percentage of EMG signal amplitude of the erector spinae muscles of the waist in the state decreased by 39.3%, verifying its beneficial effect on users.
The 2X-Hi disks of spiral galaxies

Abstract The outskirts of galaxies — especially the very extended Hi disks of galaxies — are strongly affected by their local environment. I highlight the giant 2X-Hi disks of nearby galaxies (M 83, NGC 3621, and NGC 1512), studied as part of the Local Volume Hi Survey (LVHIS), their kinematics and relation to XUV disks, signatures of tidal interactions and accretion events, the M HI - D HI relation as well as the formation of tidal dwarf galaxies. - Using multi-wavelength data, I create 3D visualisations of the gas and stars in galaxies, with the shape of their warped disks obtained through kinematic modelling of their Hi velocity fields.

Single-quantum interferometry: which-way versus which-phase information stored in an ancillary quantum system

In interferometers, the more information about a quantum’s path that is available in an ancillary quantum system (AQS), the less visibility the interference has. By use of Shannon entropy, we try to compare the amount of which-phase information with the amount of which-way information stored in the AQS of two-path interferometers with symmetric beam merging. We show that the former is less than or equal to the latter if the bipartite system of the single quantum and the AQS is initially prepared in a pure state and the interaction between the two parts is unitary. The equality holds when symmetry exists. No which-way information is obtained by the measurement that we use for extracting the which-phase information and vice versa. In order to verify the results experimentally, we propose assembling a new single-photon interferometer.
Progress of DBS devices in treating essential tremor with self-adaptation function

Nowadays, Deep Brain Stimulation (DBS) has been used in the surgical treatment of various neurological diseases, such as Essential Tremor (ET). For severe cases, surgical treatment with DBS can suppress the disease better than drug therapy. However, existing DBS devices require the physician to manually set the parameters frequently to achieve the desired therapeutic effect. In this case, adaptive DBS devices become a possible solution for this problem. Adaptive DBS equipment still faces some problems, such as the choice of implementation method, data security and how to ensure that it will not cause serious damage to human body in clinical trials. In this paper, three kinds of adaptive DBS are analyzed, including their mechanism and core algorithms. This paper can provide reference for those who study DBS devices, those who study the application of machine learning algorithms to adaptive devices, and those who want to know about adaptive DBS devices.
Diabetes mellitus complications and causes of medication non-adherence among diabetic patients in Iraq

Background: Diabetes mellitus is a most main global health problem covering nearly 415 million persons globally. Glycemic regulator has the main role in its management which mainly depends upon patient adherence to the treatment strategy. A perfect assessment of Iraqi medication adherence is necessary for the effective management of diabetes. Objective: To an awareness of Diabetes mellitus complications and causes of medication non-adherence among diabetic Iraqi patients. Materials and Methods: Study participants filled out a detailed questionnaire about Diabetes mellitus to awareness of diabetes mellitus complications and causes of medication non-adherence among diabetic patients who participated in the survey. The data collection was from 200 DM patients online from August 2021 to October 2021. Result: The study was conducted on 200 study participants. 68.5 percent of the patients were female table (1). The mean age was 60.935 years (SD ± 1.46). The majority of 158 (79%) have higher education. More than half of the respondents (65%) had an average monthly income, (11.5%) of the participants had a high monthly income, and (23.5%) had a poor monthly income. One hundred and eighty four (92%) of the participants in the study lived in urban, and (8%) only lived in rural areas Conclusion: This study provided data on awareness of diabetes complications among diabetic patients in Iraq. A comprehensive calculation of the awareness of 200 patients about the difficulties of diabetes showed that less than half of the participants had awareness.
Reissner-Nordström Black Holes Statistical Ensembles and First-Order Thermodynamic Phase Transition

We apply Debbasch proposal to obtain mean metric of coarse graining (statistical ensemble) of quantum perturbed Reissner-Nordstöm black hole (RNBH). Then we seek its thermodynamic phase transition behavior. Our calculations predict first-order phase transition which can take Bose-Einstein’s condensation behavior.
Efficient Computation of Hyperspherical Bessel Functions

Fast and accurate computations of the power spectrum of cosmic microwave background fluctuations are essential for comparing current and upcoming data sets with the large parameter space of viable cosmological models. The most efficient numerical algorithm for power spectrum calculation, recently implemented by Seljak and Zaldarriaga, involves integrating sources against spherical Bessel functions or, in the case of a non-flat universe, analogous hyperspherical Bessel functions. Evaluation of these special functions usually dominates the computation time in non-flat spatial geometries. This paper presents a highly accurate and very fast WKB approximation for computing hyperspherical Bessel functions which will greatly increase the speed of microwave background power spectrum computations in open and closed universes.
Granular Solid Hydrodynamics (GSH): from Quasi-Static Motion to Rapid Dense Flow

{\sc gsh} is a continuum mechanical theory constructed to qualitatively account for a broad range of granular phenomena. To probe and demonstrate its width, simple solutions of {\sc gsh} are related to granular phenomena and constitutive models, including (i) for vanishing shear rates: static stress distribution and propagation of elastic waves; (ii) at slow rates: critical state, shear band, the models of hypoplasticity and barodesy; (iii) at higher rates: the MIDI-model, rapid dense flow in the Bagnold regime. A unified, densely correlated understanding of granular physics emerges as a result of these phenomena ordered and explained employing a single framework.
Stability of open multiclass queueing networks via fluid models

This paper surveys recent work on the stability of open multiclass queueing networks via fluid models. We recapitulate the stability result of Dai [8]. To facilitate study of the converse of the stability result, we distinguish between the notion of fluid limit and that of fluid solution. We define the stability region of a service discipline and the global stability region of a network. Examples show that piecewise linear Lyapunov functions are powerful tools in determining stability regions. Stability, queueing networks, fluid models, scheduling, performance analysis, Harris recurrence, heavy traffic, Brownian models.
A Wideband Doherty Combiner with Phase Variation Compensation Using LTCC Applicable for High Power Transmission

In this paper, we propose a small-sized Doherty combiner with phase variation compensation using low temperature co-fired ceramic (LTCC) substrate. The proposed design theory for the Doherty combiner is derived using the phase calculation of the S-parameter based on the relation between the input and output ports. The proposed circuit is designed after determining the band edge frequency and the targeted degree of the phase balance. The proposed circuit is verified using the microstrip line and the LTCC substrate. The implemented structure, using LTCC as the substrate, is operated under a high-power test of continuous wave 50 W, the results of which also show that the amplitude and phase balance have variations within 0.2 dB and ±1°, respectively. The high-power test shows that the implemented structure is applicable for high power Doherty amplifiers or combiners.
Statistical Mechanics: Theory and Universality classes of critical points in constrained glasses

We analyze critical points that can be induced in glassy systems by the presence of constraints. These critical points are predicted by the mean ﬁeld thermodynamic approach and they are precursors of the standard glass transition in the absence of constraints. Through a deep analysis of the soft modes appearing in the replica ﬁeld theory, we can establish the universality class of these points. In the case of the ‘annealed potential’ of a symmetric coupling between two copies of the system, the critical point is in the Ising universality class. More interesting is the case of the ‘quenched potential’, where a single copy is coupled with an equilibrium reference conﬁguration, or the ‘pinned particle’ case, where a fraction of the particles is frozen in ﬁxed positions. In these cases we ﬁnd the random ﬁeld Ising model (RFIM) universality class. The eﬀective random ﬁeld is a ‘self-generated’ disorder that reﬂects the random choice of the reference conﬁguration. The RFIM representation of the critical theory predicts non-trivial relations governing the leading singular behavior of relevant correlation functions, that can be tested in numerical simulations.
Universal suppression of superfluid weight by non-magnetic disorder in $s$-wave superconductors independent of quantum geometry and band dispersion

Motivated by the experimental progress in controlling the properties of the energy bands in superconductors, significant theoretical efforts have been devoted to study the effect of the quantum geometry and the flatness of the dispersion on the superfluid weight. In conventional superconductors, where the energy bands are wide and the Fermi energy is large, the contribution due to the quantum geometry is negligible, but in the opposite limit of flat-band superconductors the superfluid weight originates purely from the quantum geometry of Bloch wave functions. Here, we study how the energy band dispersion and the quantum geometry affect the disorder-induced suppression of the superfluid weight. In particular, we consider non-magnetic disorder and s-wave superconductivity. Surprisingly, we find that the disorder-dependence of the superfluid weight is universal across a variety of models, and independent of the quantum geometry and the flatness of the dispersion. Our results suggest that a flat-band superconductor is as resilient to disorder as a conventional superconductor.
Group velocity and causality in standard relativistic resistive magnetohydrodynamics

Group velocity of electromagnetic waves in plasmas derived by standard relativistic resistive magnetohydrodynamics equations is superluminal. If we assume that the group velocity represents the propagation velocity of a signal, we have to worry about the causality problem. That is, some acausal phenomena may be induced, such as information transportation to the absolute past and a spontaneous decrease in the entropy. Here, we tried to find the acausal phenomena using standard relativistic resistive magnetohydrodynamics numerical simulations in the suggested situation of the acausal phenomena. The calculation results showed that even in such situations no acausal effect happens. The numerical result with respect to the velocity limit of the information transportation is consistent with a linear theory of wave train propagation. Our results assure that we can use these equations without the problems of acausal phenomena.
Catalog of Volcanic Eruptions during the Past 2, 000 Years in Japan

This paper contains a catalog of volcanic eruptions of magnitude (M) 3 or greater during the past 2,000 years in Japan (Table 1). The largest eruption of a volcano during this period and eruptions that caused loss of human life are also listed even if they did not reach M3. Many of the eruptions correspond with an identified deposit, but some are knownonly from human documents. Documents of ash-fall and (Pele's) hair-fall compiled by Omori (1918) are all listed, even those that may not describe volcanic eruptions. Fatal events including gas accidents are also covered whether or not they were caused by an eruption. For Fuji volcano, listed eruptions which occurred prior to 800 AD could not be dated with accuracy, but magnitude data is reliable. As defining an eruption is arbitrary in some cases, I use the following criteria: 1) Simultaneous eruptions 10 or more kilometers apart are treated as separate occurrences. 2) An eruption less than 10 years following an eruption of M3 or greater is not an independent eruption. 3) An eruption less than 1 year after the preceding eruption is not new. The total number of listings in the catalog is approximately 400.
Theoretical interpretation of a spin-two diphoton excess

A spin-two resonance would have couplings to the SM, suppressed via higher-dimensional operators. Therefore, a sizeable cross-section would indicate that the scale of additional new phenomena cannot be too far above the 750 GeV mark. Below I present some theoretical arguments to place the resonance in a wider framework: a manifestation of new extra-dimensions, or a glueball of a new strong sector. In each case, I identify some conditions the UV theory must satisfy to accommodate other experimental bounds. Based on those, I draw correlations with associated phenomena we expect to find in future searches.
CORE AND WING DENSITIES OF ASYMMETRIC CORONAL SPECTRAL PROFILES: IMPLICATIONS FOR THE MASS SUPPLY OF THE SOLAR CORONA

Recent solar spectroscopic observations have shown that coronal spectral lines can exhibit asymmetric profiles, with enhanced emissions at their blue wings. These asymmetries correspond to rapidly upflowing plasmas at speeds exceeding ≈50 km s−1. Here, we perform a study of the density of the rapidly upflowing material and compare it with that of the line core that corresponds to the bulk of the plasma. For this task, we use spectroscopic observations of several active regions taken by the Extreme Ultraviolet Imaging Spectrometer of the Hinode mission. The density sensitive ratio of the Fe xiv lines at 264.78 and 274.20 Å is used to determine wing and core densities. We compute the ratio of the blue wing density to the core density and find that most values are of order unity. This is consistent with the predictions for coronal nanoflares if most of the observed coronal mass is supplied by chromospheric evaporation driven by the nanoflares. However, much larger blue wing-to-core density ratios are predicted if most of the coronal mass is supplied by heated material ejected with type II spicules. Our measurements do not rule out a spicule origin for the blue wing emission, but they argue against spicules being a primary source of the hot plasma in the corona. We note that only about 40% of the pixels where line blends could be safely ignored have blue wing asymmetries in both Fe xiv lines. Anticipated sub-arcsecond spatial resolution spectroscopic observations in future missions could shed more light on the origin of blue, red, and mixed asymmetries.
Phase-locked modulation delay between the poles of pulsar B1055-52

We present a detailed single pulse study of PSR B1055–52 based on observations at the Parkes radio telescope. The radio emission is found to have a complex modulation dominated by a periodicity of ∼20 times its rotational period P (0.197 s), whose phase and strength depends on pulse longitude. This periodicity exhibits a phase-locked delay of about 2.5P between the main pulse (MP) and interpulse (IP), presumed to be the opposite poles of the pulsar. This delay corresponds to a light-travel distance of many times the light-cylinder radius. More complex modulations are found within the MP on time-scales down to about 9P, and both these and the principal modulation vary strongly across the (at least) seven components which the MP and IP exhibit. The nature of the single pulse emission, which ranges from smooth and longitudinally extended to ‘spiky’, is also component-dependent. Despite these disparities, the total pulse intensity distributions at the MP and IP are virtually identical in shape, suggesting a common emission mechanism. In an attempt to account for the complex modulations, we examine a number of physical models, both intrinsic (which presuppose the pulsar to be an isolated neutron star) and extrinsic (appealing to the presence of circumstellar material to modulate the emission). Significant objections can be made to each model, so this pulsar’s behaviour patterns remain a crucial challenge to theorists.

Where the Rainbow Rises: The Strategic Adaptations of China’s LGBT NGOs to Restricted Civic Space

ABSTRACT The past decade has witnessed a new trend towards restrictions and surveillance on civil society organizations in China, which seriously affected China’s grassroots LGBT NGOs. Based on a field study of Chinese grassroots LGBT NGOs, this article explores the coping strategies utilized by these organizations to survive in a restricted civic space. Empirical evidence shows these organizations adopting various tactics to obtain funding and legitimacy. Yet despite the undeniable agency of these LGBT NGOs, they are still restricted by institutional power. While scrupulously avoiding political risks, grassroots LGBT NGOs inevitably shifted away from rights advocacy missions to become service-oriented, depoliticizing and even distorting their agendas. Consequently, the intensifying restrictions and surveillance have invisibly but saliently reshaped the structures and practices of these NGOs.
Elevated HsCRP in Chronic Obstructive Pulmonary Disease: A Prospective Study of Long-Term Outcomes After Percutaneous Coronary Intervention

Objective Anti-inflammatory therapies are reported to have additional benefits beyond lipid control for patients with cardiovascular disease. However, no study has focused on the relationship between inflammation status and long-term outcomes for chronic obstructive pulmonary disease (COPD) patients, after percutaneous coronary intervention (PCI). Methods 277 COPD-PCI patients were divided into two groups according to hsCRP status upon admission. Major adverse cardiac events (MACE) in high hsCRP patients were compared to patients with low hsCRP. Restricted cubic spline (RCS) analysis was performed using MACE hazard ratios (HR) to investigate interrelations with hsCRP, as a continuous variable. Results Patients in the high hsCRP group incurred more inflammation activation, in terms of higher white blood cell counts, neutrophil, lymphocytes, and had higher smoking rates, compared to those with lower hsCRPs. A significant increase in MACEs was observed in hsCRP high group, compared to the low hsCRP group (HR: 2.47, 95% CI: 1.22–5.00; p = 0.012). RCS curves suggest that HRs rise beyond 1.0, after the 0.24 juncture for Lg HsCRP (base 10 logarithm with hsCRP), HR per SD: 1.19 (95% CI: 0.96–1.48). Further subgroup analysis implies that elevated hsCRP is associated with a higher risk of MACEs across the sub-groups tested. Conclusion HsCRP could be a useful indicator for COPD-CAD patient prognosis, after PCI. This is because hsCRP highlights inflammation activation. More multi-center research, designed for COPD-CAD patients should be conducted to more accurately determine the cut-off value for hsCRP.
