Published: June 2022

Aim. To assess association of different dynamics of sex hormones with 10-year survival in men with congestive heart failure (CHF) and implanted cardiac resynchronization therapy (CRT) devices.Methods. Based on tercile of testosterone at the end of the study (TESend), 157 men with CRT (mean age 58.7±9.7 years old; 95 men (60.5%) w/ ischemic CHF) were divided into 3 groups: gr. I (n=52) - TESend<13.3 nmol/l; gr. II (n=53) - TESend>13.3<19.2 nmol/l; gr. III (n=52) - TESend>19.2 nmol/l. Parameters of echocardiography (Echo) were investigated in dynamics, N-terminal fragment of probrain natriuretic peptide (NT-proBNP), interleukin-6 (IL-6), total and free testosterone (TES), estradiol (E2), sex hormone-binding globulin (SHBG), progesterone (PGN), dehydroepiandrosterone sulfate (DHEAS), E2/TES ratio were tested in plasma. Survival in groups was assessed using Kaplan-Meier method.Results. Groups were comparable in age, presence of ischemic CHF, arterial hypertension and surgeries on myocardial revascularization. Higher incidence of atrial fibrillation, obesity, complete left bundle branch block, tendency to higher incidence of diabetes mellitus and higher body mass index was revealed in gr. I compared to gr. III. At baseline, groups didn’t differ in Echo parameters; the highest TES levels were found in gr. III. After CRT, there was less reverse cardiac remodeling, decrease of TES level (p<0.001) in gr. I vs increase of TES level in gr. II (p=0.041) and gr. III (<0.001); E2 level increased (p=0.008), levels of NT-proBNP and IL-6 decreased only in gr. III. In absence of dynamics of E2/TES index and DHEAS level in groups, E2/TES index was the highest and DHEAS level was the lowest in gr. I after CRT. 10-year survival of groups was 17.6%, 42.8%, 46.2% (Log Rank test I-II=0.016; Log Rank test I-III=0.004; Log Rank test II-III=0.528).Conclusion. Obtained results indicated different dynamics of sex steroids after CRT. Sex hormones variation pattern, interrelated with increase in levels of testosterone, estradiol, dehydroepiandrosterone sulfate and decrease in testosterone to estradiol ratio, was associated with better 10-year survival in men with implantable CRT devices with greater reverse cardiac remodeling and reduction in activity of systemic immune inflammation.
Dual resonance modes in two-port SAW resonator sensors: an analysis through scattering matrix approach
Authors: Zhihong Keenan Yap , Mohanan Ajay Achath , Ramakrishnan Narayanan 
Published: June 2022

Abstract
We report dual resonance modes occurring in two-port surface acoustic wave (SAW) resonators attached with typical sensing film and investigated the significance in sensing applications. Two-port SAW resonators operating at 303 MHz frequency were modelled using the scattering matrix approach and resonance frequency characteristics of the resonators were studied for mass loading caused by an arbitrary film attached between the interdigital transducers of the resonator. Depending on the mass loading, symmetric and antisymmetric modes occur around the near resonance frequency of the SAW device. Either a single-mode or both modes are dominant depending on the phase shift caused by the mass loading of the film. Choosing arbitrary film thickness could result in complexity to track the resonance frequency shift and degrade sensing performance. The approach used for analysis can aid to determine the optimum sensing film thickness for two port SAW resonator-based sensors that can exhibit better linearity.
Ferroelectric polarization of tetragonal BiFeO3—an approach from DFT calculations for BiFeO3–BaTiO3 superlattices—
Authors: Noguchi Yuji , Matsuo Hiroki 
Published: June 2022

Abstract
Density functional theory calculations are conducted for tetragonal BiFeO3–BaTiO3 superlattices to investigate the influence of electronic structures on ferroelectric spontaneous polarization (P
s). When the number of the perovskite unit cells in one layer (N) is decreased below 10, the P
s starts to decrease from the volume-averaged one (50.9 μC cm−2) and eventually becomes half at N = 1. In the BiFeO3 cell (N = ∞) with a large P
s (73.3 μC cm−2), a covalent bond arising from a Bi_6p-O_2p orbital interaction is extended through a Bi–O network and stereo-chemical lone-pair electrons of Bi are accommodated in the opposite direction of the polar c axis. In the superlattice with N = 1, the Bi–O network cannot be developed by the presence of Ba, and then the Bi–O bond becomes ionic. We show that the large P
s of the BiFeO3 cell originates from the Bi_6p-O_2p mixing superimposed on the stereo-chemical nature of the lone-pair electrons of Bi.
Strong light confinement and optical force enhancement in phosphorene with acoustic plasmons
Authors: Wang Hao-yu , Ma Rui , Liu Gui-dong , Wang Ling-ling , Lin Qi 
Published: June 2022

Abstract
We analytically and numerically investigate the acoustic plasmon mode in phosphorene placed above a metallic substrate with a finite gap width. Combined with finite-difference time-domain simulations, we demonstrate the responses of evanescent waves in the phosphorene-insulator-metal (PIM) waveguide, involving field enhancement, light confinement, and optical force. It turned out that owing to a large amount of light energy squeezed inside the gap, the light confinement ratio and optical force along the armchair direction in the PIM waveguide can be up to 96% and 6930 pN mW−1, respectively. Our results may manifest in diverse optoelectronic applications like optical tweezers.

<p>Yet, little is known about the direction of abnormal coupling in conjunction with its degree between joints—muscles—of interest. In this study, we address the directionality of pathological neural couplings between joints, and variability in the degree of them, in the upper extremity post stroke. To evaluate the direction of interjoint coupling, joint motion and muscle activity in an involuntary mode while another joint—muscle—was voluntarily activated were assessed in comparison to those made in a volitional mode, focusing on the shoulder, elbow and wrist joints. Overall, involuntary activation of the wrist flexor in the stroke group is observed when muscles of a more proximal joint voluntarily activate (p < 0.1 and p <0.05), while activation of the wrist flexor does not lead to involuntary activation of the shoulder muscles and elbow flexor, in comparison to the healthy group. In particular, in the stroke group who is assumed to have a severe loss of the corticospinal system, the wrist extensor is subordinately activated by those about the other joints voluntarily activated (p < 0.05) while it does not cause activations of those about the other joints. These findings indicate that stroke-caused synergies could be directional.</p>

<p>The proliferation of Internet of Things (IoT) systems is having a profound impact across all aspects of life. Recognising and identifying particular users is central to delivering the personalised experience that citizens want to experience, and that organisations wish to deliver. This article presents a survey of human-computer interaction-based (HCI-based) and natural habits-based behavioral biometrics that can be acquired unobtrusively through smart devices or IoT sensors for user recognition purposes. Robust and usable user recognition is also a security requirement for emerging IoT ecosystems to protect them from adversaries. Typically, it can be specified as a fundamental building block for most types of <em>human-to-things</em> accountability principles and access-control methods. However, end-users are facing numerous security and usability challenges in using currently available knowledge- and token-based recognition (<em>i.e., authentication and identification</em>) schemes. To address the limitations of conventional recognition schemes, <em>biometrics</em>, naturally come as a first choice to supporting sophisticated user recognition solutions. We perform a comprehensive review of touch-stroke, swipe, touch signature, hand-movements, voice, gait and footstep behavioral biometrics modalities. This survey analyzes the recent state-of-the-art research of these behavioral biometrics with a goal to identify their attributes and features for generating unique identification signatures. Finally, we present security, privacy, and usability evaluations that can strengthen the designing of robust and usable user recognition schemes for IoT applications.</p>

Power output estimation of WEC with HF radar measured complex representative sea states

Published: June 2022

Wave tank model testing has been widely used to assess the performance of Wave Energy Converters (WEC) in different technology readiness levels (TRL). At early stage the use of simple wave conditions such as regular waves and parametric wave spectrum JONSWAP or Pierson-Moskowitz spectrum is acceptable. However at later stages there is a need to use site specific complex wave conditions representative of potential prototype deployment sites. In previous research, 10 different regrouping methods on HF radar measured wave spectrum were tested to find out the most representative sea states for tank testing. It has been shown that by using the K-means clustering technique, the characteristics of wave conditions can be well preserved. In order to assess the power capture performance of a typical WEC in these representative sea states, the RM3 point absorber has been simulated. By analysing how well the average power output predicted from different representative sea-state selection methods compares with the total power output prediction, it is shown that the non-directional wave spectrum K-means clustering method provides the most representative sea states and, for a point absorber, with a very accurate estimation of the total power output, which is not the case by using a traditional binning method. The importance of using the complex site-specific sea states rather than simplified parametric JONSWAP sea states to obtain the accurate total power estimation has also been shown.

Published: June 2022

Most tidal turbine blades are currently made from glass or carbon fibre reinforced epoxy composites. These represent a significant part of the turbine cost, but few data are available either to validate current safety factors or to propose alternative more environmentally-friendly materials. This study, performed within the EU H2020 RealTide project, aimed to provide these data. First, a detailed investigation of the static and fatigue behavior was performed at the coupon scale, including not only those materials currently used, but also alternative recyclable thermoplastic matrix composites and natural fibre reinforced materials. Tests were performed before and after seawater saturation, in order to quantify the change in design properties with water uptake. Then a first full scale 5 meter long composite blade was designed and tested to failure. A specific test frame was built, allowing loads up to 75 tons to be applied and simulating the applied moments corresponding to service loads. Static and cyclic loads were applied and extensive instrumentation was used to detect changes in behavior, inluding optical fibres implanted during manufacture, acoustic emission recording, and specific instrumentation developed within the project.
The results have enabled numerical simulations to be verified, and this has provided confidence in the modelling tools. These were then employed in order to propose an improved design of a lower cost blade.

Atas dasar Pasal 59 ayat (3) UU Nomor 6 Tahun 2018 tentang Kekarantinaan Kesehatan dan untuk meminimalisir/memutus rantai penularan COVID-19, Pemerintah Indonesia mengeluarkan kebijakan Pembatasan Sosial Berskala Besar (PSBB) di seluruh wilayah Indonesia. Selain berdampak positif, kebijakan ini juga berdampak negatif karena menyasar bidang perekonomian. Permasalahan perekonomian dirasakan oleh semua kalangan masyarakat, mulai dari menengah kebawah hingga menengah keatas. PSBB yang terdiri atas peliburan sekolah dan tempat kerja, pembatasan kegiatan keagamaan, dan pembatasan kegiatan di tempat atau fasilitas umum, menghasilkan efek domino. Efek ini berwujud pada perusahan yang meliburkan sebagian karyawannya atau ditutup sementara. Akibatnya perushaan pailit dan harus memutus hubunga kerja dengan para pegawainya. Guna menangani permasalah tersebut, Pemerintah mensubsidi anggaran sebesar Rp. 110 Triliun untuk membantu kelangsungan hidup para masyarakat Indonesia (termasuk para pegawai tersebut). Adapun, itu berwujud Program Keluarga Harapan, Sembako, Kartu Prakerja, Subsidi Listrik, dan BLT (Bantuan Langsung Tunai).

The Behavior of HgMn Stars in the Far-UV—Paper 7: HR 6000
Authors: Monier Richard 
Published: June 2022

Abstract
The analysis of nine high resolution SWP spectra of the chemically peculiar star HR 6000 recorded by the International Ultraviolet Explorer reveals low amplitude variations of the far-ultraviolet flux (about 15% at 1500 Å) over the various observations with IUE. These variations could be caused by horizontal gradients of abundances of chemical elements over the surface of HR 6000.
