The decay of effective contact rates throughout the three epidemic stages is demonstrated. Evidence for the sign-switching of the dominant eigenvalue is given and the order parameter and its stage-3 remnant are identified. The presumed impacts of interventions measures implemented in Thailand are discussed in this context.The ability to control, manipulate, and read out nanomechanical resonators is of great significance for many applications. In this work, we start by constructing a nonlinear dynamic model that is deduced from the fundamental beam-photon-electron interaction and energy band theories, with the aim of describing a complicated cavity-free optomechanical coupling process. Based on the model established, we first reveal the manipulation of a resonator's response, including softening and hardening effects due to laser injection. By driving the laser parametrically, we comprehensively investigate the control of the resonator's dynamics, in particular, in the nonlinear regime. It is found that both the laser power and frequency can be used to directly manipulate the NEMS resonator's dynamics, e.g., by amplitude amplification, periodicity changes, and periodic-chaotic state conversion. We then provide bifurcation diagrams, which evidence a deterministic evolution of dynamics. Finally, we perform a special study of the control of chaotic states of the nanomechanical resonator using laser parametric driving. The maximal Lyapunov exponents together with time series calculation show that the chaotic states can be controlled at a few specific frequency points of the injecting laser. This work not only provides guidance for using lasers to control nanoscale resonators, but also sheds light on the exploration of novel applications based on nonlinear NEMS resonators.The role of silver localized surface plasmons (LSPs) on the luminescence of a Si(111)-(7 × 7) surface has been investigated by scanning tunneling microscopy (STM) with a silver tip at 77 K. On a bare Si(111)-(7 × 7) surface, a characteristic peak at 1.85 eV dominates the STM-induced luminescence spectrum, although the luminescence intensity is extremely weak. Once Ag atoms are deposited onto the Si surface to form islands with a few atomic layers, it is found that the intensity of the characteristic peak from the Si surface underneath the Ag islands is significantly enhanced by about one order. In addition to the luminescence from the Si surface, light emission originating from the irradiation decay of the Ag plasmons is also detected. Such great enhancement of the luminescence from the Si surface is attributed to the strong coupling between the surface states of the Si and the LSPs of the Ag islands.Controlled graphene growth on a substrate without the use of catalysts is of great importance for industrial applications. Here, we report thickness-controlled graphene growth directly on a silicon substrate placed in a low-density microwave plasma environment using a laser. Graphene is relatively easy to grow in high-density plasma; however, low-density plasma lacks the sufficient energy and environment required for graphene synthesis. This study reports that laser irradiation on silicon samples in a low-density plasma region nucleates graphene, and growth is controlled with laser exposure time and power. A graphene-silicon junction is thus formed and shows an enhanced (1.7 mA) short-circuit current as compared to one grown in high-density plasma (50μA) without the laser effects. Synthesized graphene is characterized by Raman spectroscopy, atomic force microscopy to investigate surface morphology and Hall effect measurements for electronic properties. The key aspect of this report is the use of a laser to grow graphene directly on the silicon substrate by ensuring that the bulk resistance of the silicon is unaffected by ion bombardment. Additionally, it is observed that graphene grain size varies in proportion to laser power. This report can help in the growth of large-area graphene directly on silicon or other substrates at reduced substrate temperatures with advanced electronic properties for industrial applications.

Multiple Sclerosis (MS), occupies the first row among the diseases which leads to loss of neurological ability without depending on a trauma in the adults. Reflexology is one of complementary therapies based on activating a body's power to recover itself by special hand techniques applied to feet and hands. Positive changes in spasticity, pain, fatigue, depression, cortisol levels, anxiety, and blood pressure levels have been observed in MS patients after reflexology.

This study was conducted to determine the effect of reflexology on pain, fatigue and quality of life in MS patients.

The study was conducted experimentally by taking pretest and repeated measurements on reflexology and control groups determined by simple randomization.

The study took place in the neurology clinics at two university hospitals in Turkey.

Potential participants were 685 patients at the clinics who had been diagnosed with MS 6 months at least prior to the study. Of that group, 66 patients were included in the study, 33 in cates that reflexology can be used as a complementary and alternative therapy to reduce pain and fatigue and enhance quality of life in MS patients.

Platelet hyperactivity has a crucial role in initiating vascular thrombosis and subsequent cardiovascular disease (CVD).

This study aimed to assess the effect of anthocyanins (AC) on platelet aggregation and activation and lipid profile.

A total of 26 healthy participants consumed 320 mg of AC/day in the form of Medox® capsules for 28 days.

This study was conducted in the laboratories of the School of Medical Sciences, Griffith University, Gold Coast, Australia.

A total of 26 randomly recruited healthy 25- to 75-year-old participants completed this study.

Fasting blood samples were collected pre- and post-the intervention period to perform platelet activation studies by measuring platelet surface marker expression of CD41a and P-selectin, and platelet-monocyte aggregates in adenosine diphosphate (ADP) stimulated platelets. Platelet aggregation studies were performed by stimulating platelets with various agonists such as ADP, collagen and arachidonic acid. Full blood examination, coagulation and biochemistry profile analyses were also performed pre- and post-intervention. Flow cytometric analysis showed a significant effect of AC on the expression of P-selectin as measured by the platelet surface expression of CD62p.

There was a significant reduction of ADP-stimulated platelet aggregation. Hematologic analysis showed a significant reduction of mean platelet volume, mean cell hemoglobin, and mean cell hemoglobin concentration. Coagulation analysis demonstrated significant attenuation of fibrinogen level in the blood.

This study showed inhibition of platelet activity, platelet aggregation and mean platelet volume (MPV). These results suggest that AC has a positive impact on attenuating platelet activity, which might minimize thrombotic risk.

To investigate the relationship between physical fitness and repeated high-intensity effort (RHIE) ability in elite rugby union players, depending on playing position.

Thirty-nine players underwent a fitness testing battery composed of a body composition assessment, upper-body strength (1-repetition maximum bench press and 1-repetition maximum bench row), lower-body strength (6-repetition maximum back squat), and power (countermovement jump, countermovement jump with arms, and 20-m sprint), as well as aerobic fitness (Bronco test) and RHIE tests over a 1-week period. Pearson linear correlations were used to quantify relationships between fitness tests and the RHIE performance outcomes (total sprint time [TST] and percentage decrement [%D]). Thereafter, a stepwise multiple regression model was used to verify the influence of physical fitness measures on RHIE ability.

TST was strongly to very strongly associated to body fat (BF, r = .82, P < .01), the 20-m sprint (r = .86, P < .01), countermovement jump (r = -.
