AbstractProlactin has many physiological effects and seems to be involved in the human
quality of life and well-being. The aim of this study was to describe health
related quality of life, fatigue and daytime sleepiness in women with untreated
hyperprolactinemia. In total 32 women (mean age 37.0±10.9 years) with
verified hyperprolactinemia completed a questionnaire including questions on
fatigue, measured with the Swedish version of the Fatigue Impact Scale (FIS),
propensity to fall in sleep, measured with the Swedish version of the Epworth
Sleepiness Scale (ESS), and Health related quality of life (HRQoL), measured by
the Short-Form-36 scale (SF-36). For comparison Swedish normative data were
used. The women were also interviewed regarding different symptoms related to
hyperprolactinemia and the answers were analyzed using qualitative content
analysis. HRQoL, as measured with SF-36, was significantly lower in all
dimensions, except in physical function, compared to the Swedish reference
population. Total FIS was 54.3 (41.1) and mean score on the ESS was 8.7 (4.2)
indicating increased fatigue and deterioration in night sleep. The women felt
very tired, and several of them rarely felt rested in the morning. The restless
night sleep and the fatigue during the daytime got them to feel feeble and
sometimes to find it difficult to concentrate, which affected both their mood
and life in general. Women diagnosed with hyperprolactinemia reported
deterioration in night sleep, increased rate of fatigue, and a reduced health
related quality of life in comparison with the reference population.

Published: February 2023

AbstractThe aim of the study was to evaluate the hemodynamic and oximetric changes in patients with parallel circulation (Norwood, hybrid, and BT-shunted) after sodium bicarbonate bolus administration. This study was a retrospective analysis of physiologic data. To eliminate confounders, sodium bicarbonate boluses concurrently administered with normal saline, 5% albumin, epinephrine boluses, blood transfusions, change in vasoactive inotropic score or mechanical circulatory support were excluded. Blood pressure, arterial oxygen saturation, heart rate (HR), and cerebral and renal near infrared spectroscopy were continuously recorded from 1-hour pre to 1-hour post each intervention. Out of 429 boluses, 293 boluses met the inclusion criteria. Measurements show an increase in blood pressure (p = 0.01) and HR (p < 0.01), and a decrease in pulmonary-to-systemic flow ratio (p = 0.02) and renal oxygen extraction ratio (rOER) (p = 0.04) at some point during the first hour postbolus. The arterial oxygen saturation increased, and the rOER decreased for those patients with pre-bolus pH < 7.20 and/or pre-bolus serum bicarbonate level < 18 mEq/L, according to linear regression models (p < 0.05). Sodium bicarbonate was associated with improvement of hemodynamic and oximetric parameters in this cohort, particularly for those patients with pH < 7.20 and/or serum bicarbonate level < 18 mEq/L. This finding is consistent with an increase in cardiac output due to the removal of the acidotic negative inotropic effect by the sodium bicarbonate.

Published: February 2023

AbstractDistal arthrogryposis with impaired proprioception and touch (DAIPT) is an autosomal recessive neurogenetic disorder caused by homozygous pathogenic variants in the PIEZO2 gene. Here we present four Omani families with multiple affected members with DAIPT. The genetic diagnosis was established by whole exome sequencing and we identified a previously unreported homozygous missense variant PIEZO2: c.1591T > C, P.(Trp531Arg) in one family with two affected members. All patients showed clinical manifestation shortly after birth including transient respiratory insufficiency, significant hypotonia, and gross motor developmental delay with preserved cognitive function. The skeletal manifestation including arthrogryposis is more pronounced with age as we saw in our older patient. This case report will be of importance for physicians and genetic counsellors for faster diagnosis and for offering carrier testing for at-risk family members as part of the premarital testing program, which could help in reducing the burden of this disorder.
Cuffed Endotracheal Tubes in Neonates
Authors: Gaspar Nélia Santos , Rocha Gustavo , Gonçalves Américo 
Published: February 2023

AbstractCuffed endotracheal tubes (ETTs) are becoming increasingly used in neonates; nevertheless, current data in the literature mostly include infants over 3,000 g in weight. The aim of this study was to compare the use of cuffed and uncuffed ETTs in neonates in the neonatal intensive care unit of a tertiary children's hospital, assessing the presence of airway complications. We performed a single-center retrospective cohort study. Our study included all term neonates receiving cuffed ETTs over the period from January 2019 to December 2021. The controls were all neonates receiving an uncuffed ETT over the same period. Twenty-five patients were intubated with cuffed ETTs in the study period. The group receiving cuffed ETTs was compared with 53 patients receiving uncuffed ETTs. All cuffed ETTs were inserted in the operating room by anesthesiologists. Comparing the outcomes of the cuffed ETT group with controls, there were no significant differences in the number of unplanned extubations, reintubation episodes, ventilator-associated pneumonia, episodes of atelectasis, the use of dexamethasone, or vocal cord paresis. No unplanned extubation was observed in the cuffed ETT group, and no cases of subglottic stenosis were observed in either of the groups. This retrospective study with a small sample size suggests that the use of cuffed ETTs in surgical patients >2,000 g in weight is not associated with an increase in airway complications. Well-designed randomized controlled trials are needed to compare cuffed ETTs with uncuffed ETTs.
Mapping spectroscopic micro-ellipsometry with sub-5 microns lateral resolution and simultaneous broadband acquisition at multiple angles
Authors: Kenaz Ralfy , Rapaport Ronen 
Published: February 2023

Spectroscopic ellipsometry is a widely used optical technique in both industry and research for determining the optical properties and thickness of thin films. The effective use of spectroscopic ellipsometry on micro-structures is inhibited by technical limitations on the lateral resolution and data acquisition rate. Here, we introduce a spectroscopic micro-ellipsometer (SME), capable of recording spectrally resolved ellipsometric data simultaneously at multiple angles of incidence in a single measurement of a few seconds, with a lateral resolution down to 2 μm in the visible spectral range. The SME can be easily integrated into generic optical microscopes by the addition of a few standard optical components. We demonstrate complex refractive index and thickness measurements by using the SME, which are in excellent agreement with a commercial spectroscopic ellipsometer. The high lateral resolution is displayed by complex refractive index and thickness maps over micron-scale areas. As an application for its accuracy and high lateral resolution, the SME can characterize the optical properties and number of layers of exfoliated transition-metal dichalcogenides and graphene, for structures that are a few microns in size.
Non-literal uses of proper names in XYZ constructions
Authors: Wałaszewska Ewa 
Published: February 2023

Abstract
The paper focuses on non-literal uses of proper names in XYZ constructions, such as the use of the personal name
Donald Trump in Boris Johnson is the Donald Trump of UK politics or ‘5G’ is the
Donald Trump of telecom, and argues that such uses can be best accounted for by relevance theory. While in their
primary use, proper names uniquely denote specific individuals and have no meaning on their own, in their secondary uses, they act
as common nouns, capable of conveying non-literal meanings. In relevance theory, such non-literal uses can be explained in terms
of lexical modulation or ad hoc concept formation. The analysis of selected examples shows that while some of the XYZ
constructions can be seen as metaphors, others are better described as category extensions, and it substantiates the
relevance-theoretic claim that there is no clear cut-off point between the two varieties of loose use.

Published: February 2023

ABSTRACTThe purpose of this investigation was to examine neuromuscular function, muscle fatigue, rating of perceived exertion (RPE), and muscle swelling between isokinetic and isotonic leg extensions with blood flow restriction (BFR). Fourteen (21 ± 2years; 160cm ± 3.8; 61kg ± 9.1) trained women performed 75 (1 × 30,3 × 15) submaximal (30% of maximal strength), unilateral, isokinetic and isotonic leg extensions with BFR (60% of total arterial occlusion pressure). Before and after exercise, subjects performed maximal voluntary isometric contractions (MVIC) and muscle thickness (MT) was assessed with ultrasound. RPE was recorded across all sets and surface electromyography (EMG) was assessed during the MVIC muscle actions. Separate repeated measures ANOVAs were used to examine MVIC, MT, RPE and neuromuscular function. There were greater reductions in MVIC torque and EMG mean power frequency following isotonic (46.2 ± 17.1%; 16.4 ± 7.9%) than isokinetic (17.9 ± 10.9%;6.5 ± 6.3%). RPE was also higher during isotonic (7.5 ± 2.2), than isokinetic (5.7 ± 1.9). There were no differences in EMG amplitude or MT increases (20 ± 2.1%) between conditions. Isotonic BFR elicited greater fatigue‐induced decreases in muscular strength and greater RPE than isokinetic BFR, but similar MT and muscle excitation responses for both conditions. Therefore, both isokinetic and isotonic may induce similar acute physiological responses, but isotonic BFR was associated with greater muscle fatigue and perceived effort.

Published: February 2023

Abstract
Pressure is a fundamental thermodynamic variable that can create exotic materials and modulate transport properties, motivating prosperous progress in multiple fields. As for inorganic thermoelectric materials, pressure is an indispensable condition during the preparation process, which is employed to compress raw powders into the specific shape of solid-state materials for performing properties characterization. In addition to this function, the extra influence of pressure on thermoelectric performance is frequently underestimated and even overlooked. In this review, we summarize recent progress and achievements of pressure-induced structure and performance in thermoelectrics, emphatically involving the modulation of pressure on crystal structure, electrical transport properties, microstructure, and thermal conductivity. According to various studies, the modulated mechanism of pressure on these items above has been discussed in detail, and the perspectives and strategies have been proposed with respect to applying pressure to improve thermoelectric performance. Overall, the purpose of the review is supposed to enrich the understanding of the mechanisms in pressure-induced transport properties and provide a guidance to rationally design a structural pattern to improve thermoelectric performance.
A tunable sub-wavelength acoustic imaging planar metalens
Authors: Zuo Gang , Huang Zhen , Ma Fuyin 
Published: February 2023

Abstract
Acoustic metamaterials can be used to fabricate metalenses that can achieve sub-wavelength imaging resolution, but the reported devices are often passive and cannot adapt to changes in working frequency. To this end, we propose a dynamic tunable acoustic imaging planar metalens by introducing a telescopic tube between two sets of perforated Fabry–Pérot resonant metamaterial lenses to adjust the combined length of the imaging hole. Since the working frequency of the Fabry–Pérot resonant structure is directly related to the thickness of the metalens, continuous adjustment of the working frequency can be achieved by continuously changing the length of the imaging hole. This Fabry–Pérot resonant perforated structure belongs to an acoustic metamaterial unit, which can be resonantly coupled with evanescent waves to enhance the evanescent waves carrying detailed information of objects, thereby realizing high-resolution imaging. Relying on the resonance tunneling effect of the imaging hole, high acoustic transmittance can be obtained at the working frequency, ensuring excellent imaging quality. Through numerical calculation and experimental measurement results, the imaging performance and tunability of the tunable sub-wavelength acoustic imaging metalens are demonstrated. The proposed tunable acoustic planar metalens overcomes the shortcomings of the fixed working frequency of passive metalenses and has potential applications in the fields of ultrasound imaging and medical diagnosis.
Proton-neutron entanglement in the nuclear shell model
Authors: Johnson Calvin W , Gorton Oliver C 
Published: February 2023

Abstract
We compute the proton-neutron entanglement entropy in the interacting nuclear shell model for a variety of nuclides and interactions. Some results make intuitive sense, for example, that the shell structure, as governed by single-particle and monopole energies, strongly affects the energetically available space and thus the entanglement entropy. We also find a surprising result: that the entanglement entropy at low excitation energy tends to decrease for nuclides when N ≠ Z. While we provide evidence this arises from the physical nuclear force by contrasting with random two-body interactions which shows no such decrease, the exact mechanism is unclear. Nonetheless, the low entanglement suggests that in models of neutron-rich nuclides, the coupling between protons and neutrons may be less computationally demanding than one might otherwise expect.
Nonlinear Hall effect in monolayer phosphorene with broken inversion symmetry
Authors: Yar Abdullah , Sultana Rifat 
Published: February 2023

Abstract
Nonlinear Hall effect (NLHE), a new member of the family of Hall effects, in monolayer phosphorene is investigated. We find that phosphorene exhibits pronounced NLHE, arising from the dipole moment of the Berry curvature induced by the proximity effect that breaks the inversion symmetry of the system. Remarkably, the nonlinear Hall response exhibits central minimum with a width on the order of the band gap, followed by two resonance-like peaks. Interestingly, each resonance peak of the Hall response shifts in the negative region of the chemical potential which is consistent with the shift of valence and conduction bands in the energy spectrum of monolayer phosphorene. It is observed that the two peaks are asymmetric, originated from anisotropy in the band structure of phosphorene. It is shown that the NLHE is very sensitive to the band gap and temperature of the system. Moreover, we find that a phase transition occurs in the nonlinear Hall response and nonlinear spin Hall conductivity of the system under the influence of spin–orbit interaction, tuned by the strength of interaction and band gap induced in the energy spectrum of monolayer phosphorene with broken inversion symmetry.

Published: February 2023

Abstract
The early faults of rolling bearings are the common causes of rotating machinery failures. Rolling bearings with local faults usually generate periodic shocks during operation, but the pulse information is easily masked by a large number of random shocks and noise. To effectively diagnose the early fault information of rolling bearings, a dual-dimensional sparse low-rank (DDSLR) model is proposed in this paper, which can simultaneously extract the sparsity within and across groups and periodic self-similarity of fault signal. In the DDSLR model, a newly developed dimension transformation operator is used to transform the fault signal between one-dimensional vector and low-rank matrix, and the periodic overlapping group shrinkage and truncated nuclear norm are used to improve the traditional sparse low-rank model. In addition, the setting rules of periodic prior and parameters in the DDSLR model are discussed, so that the DDSLR model has certain adaptive ability. Finally, the DDSLR model is proved to be a multi-convex optimization problem, and its solution algorithm is derived by using soft threshold operator and majorization-minimization algorithm under the framework of block coordinate descent method. The results of simulation analysis and experiments show that the proposed DDSLR model has higher fault signal estimation accuracy and better fault feature extraction performance than some classical sparse noise reduction models.

Published: February 2023

Abstract
Single-sensor zero-velocity-update (ZUPT)-aided pedestrian inertial navigation system (PINS) is a conventional method. However, the single-sensor systematic error still causes imprecise estimation of step length and high drift of orientation. In this study, three magnetometers and inertial measurement units are mounted on single-leg toe, shank, and thigh, respectively. Gaits are divided into two phases: stance and swing. Based on the biomechanical characteristics of a human lower limb, a velocity-position estimation algorithm is proposed. The positions of the three sensors are fused by dynamic geometric relationships, which are formulated through the natural lower-limb model and attitude estimation. A velocity-difference constraint is proposed to suppress the divergence of velocity, and Coriolis-based velocity correction is designed to observe velocities of the toe, shank, and thigh at the stance phase. A MAHONY-linear-Kalman framework separately estimates attitudes, velocities, and positions to reduce calculations. The proposed method is compared with foot-mounted, shank-mounted, and thigh-mounted ZUPT-aided PINS as well as a dual-sensor foot-to-foot algorithm through experiments. In the flat terrain experiment, compared with the errors of the Shank-mounted INS, the Thigh-mounted INS, the Foot-mounted INS, the Foot-to-Foot Constraint Method, the root mean squared error (RMSE) of the proposed method can be reduced by 40.34%, 71.85%, 29.53%, and 7.08%, respectively. In the slope experiment, compared with the other four methods, the RMSE of the proposed method can be reduced by 80%, 86.74%, 67.54%, and 61.86%, respectively. In the natural terrain experiment, compared with the other four methods, the RMSE of the proposed method can be reduced by 81.63%, 96.27%, 70%, and 60.87% respectively. The results show that the proposed method greatly suppresses the positioning and orientation errors in different scenes.

Published: February 2023

Abstract
Magnetic skyrmions are topologically protected spin textures and they are suitable for future logic-in-memory applications for energy-efficient, high-speed information processing and computing technologies. In this work, we have demonstrated skyrmion-based 3 bit majority logic gate using micromagnetic simulations. The skyrmion motion is controlled by introducing a gate that works on voltage controlled magnetic anisotropy. Here, the inhomogeneous magnetic anisotropy behaves as a tunable potential barrier/well that modulates the skyrmion trajectory in the structure for the successful implementation of the majority logic gate. In addition, several other effects such as skyrmion–skyrmion topological repulsion, skyrmion-edge repulsion, spin–orbit torque and skyrmion Hall effect have been shown to govern the logic functionalities. We have systematically presented the robust logic operations by varying the current density, magnetic anisotropy, voltage-controlled gate dimension and geometrical parameters of the logic device. The skyrmion Hall angle is monitored to understand the trajectory and stability of the skyrmion as a function of time in the logic device. The results demonstrate a novel method to achieve majority logic by using voltage controlled magnetic anisotropy which further opens up a new route for skyrmion-based low-power and high-speed computing devices.

Published: February 2023

Abstract
As a lithium-ion battery cathode material with high theoretical capacity, the application of V2O5 is limited by its unstable structure and low intrinsic conductivity. In this paper, we report a Fe doped V2O5 nanowire with a layered structure of 200–300 nm diameter prepared by electrostatic spinning technique. The 3Fe-V2O5 electrode exhibited a superb capacity of 436.9 mAh g−1 in the first cycle when tested in the voltage range of 2.0–4.0 V at current density of 100 mA g–1, far exceeding its theoretical capacity (294 mAh g−1), and the high capacity of 312 mAh g−1 was still maintained after 50 cycles. The superb performance is mainly attributed to its unique layered nanowire structure and the enhanced electrical conductivity as well as optimized structure brought by Fe-doping. This work made the homogeneous doping and nanosizing of the material easily achieved through electrostatic spinning technology, leading to an increase in the initial capacity of the V2O5 cathode material and the cycling stability compared to the pure V2O5, which is an extremely meaningful exploration.
