Adverse Effects, Smoking, Alcohol Consumption, and Quality of Life during Long-Term Oxygen Therapy: A Nationwide Study

Rationale Long-term oxygen therapy (LTOT) is prescribed for at least 15 hours per day and often used by patients for several years, but knowledge is limited regarding adverse effects, risk exposures, and health-related quality of life (HrQoL) among those treated. Objectives To determine the prevalence of adverse effects, smoking, and alcohol consumption and their relations to HrQoL among patients treated with LTOT. Methods This was a cross-sectional survey of a randomized sample of adults with ongoing LTOT in the Swedish National Registry for Respiratory Failure (Swedevox). Patient characteristics and the prevalence of 26 prespecified adverse effects, smoking, and alcohol consumption, were compared between respondents with better and worse HrQoL on the chronic obstructive pulmonary disease assessment test. Results A total of 151 respondents were included (mean age, 74.7 yr [standard deviation, 8.6 yr]; 58.9% women; median LTOT duration, 2.2 yr [interquartile range, 1.0–3.8 yr]). Characteristics upon starting LTOT were similar between respondents and nonrespondents. Active smoking was very rare (n = 4, 2.6%). For alcohol use, 67.2% of participants reported no consumption during an average week, whereas risk use was reported by 25.8% of men and 16.9% of women. The most prevalent adverse effects were reduced mobility or physical activity (70.9%), dry mouth (69.5%), congestion or nasal drip (61.6%), increased tiredness (57.0%), and dry nose (53.0%). Patients with higher numbers of total and systemic adverse effects experienced worse HrQoL, whereas no associations were found for smoking status or alcohol consumption. The majority (54.8%) of adverse effects were untreated and unreported to health professionals. Conclusions Adverse effects are common among patients with LTOT and are associated with worse HrQoL. As the majority of adverse effects had not been discussed or treated, structured assessment and management of risk exposures and adverse effects is warranted.
Psychological experience and social reintegration needs of young stroke patients: a systematic review and meta-aggregation of qualitative studies

ABSTRACT Background The visible physical dysfunction and invisible psychological effects after stroke prevent young patients from returning to their pre-stroke roles and social activities. Purpose/Aim To comprehensively analyze the psychological experience and social reintegration needs of young stroke patients, which may be beneficial for improving quality of life and social reintegration after stroke. Methods We conducted a comprehensive literature search of 10 databases. The screening and quality assessment of the included articles were performed by the Qualitative Assessment and Review Instrument (QARI). Meta-aggregation was conducted to synthesize the findings of the included studies. We summarized the certainty of confidence using the Confidence in Evidence from Reviews of Qualitative Research (CERQual) approach. Results A total of 5506 studies were screened, of which 12 were included. Data synthesis suggested two new themes: (a) the self-growth process from denial of stroke to accepting stroke (high CERQual confidence), and (b) desire to regain pre-stroke normality, but having difficulty in the social reintegration process (high CERQual confidence). Conclusion Stroke, as a traumatic event, disrupts the life structure of young patients, and their needs of reintegration are not adequately considered. Interventions based on the principle of individuation should focus on this issue to restore continuity in life after stroke.
Effects of Hatha yoga on cognitive functions in the elderly: a cross-sectional study

Abstract This study aimed to investigate the effects of Hatha yoga practice on cognitive functions in the elderly. Thirty healthy older men participated in this study. They belonged to 2 groups. The first group included 15 Hatha yoga practitioners for at least 2 years. The control group involved 15 male older adults who shared the same characteristics (age, years of formal education, and level of physical activity) as the Hatha yoga group but were naive to yoga, meditation, or any mind-body intervention. Neuropsychological tests were applied to measure selective attention, sustained attention, episodic memory, and processing speed. The following tests were administered: The French adaptation of the Victoria Stroop test, the Zazzo’s Cancellation Task, the Five Word Test, and a battery of computerized tests to evaluate reaction time. Long-term Hatha yoga practice showed promising results related to executive functions and reaction time, but no significant difference was found between the two groups in episodic memory and sustained attention although a trend of improvement was observed in favor of Hatha yoga practitioners. In conclusion, long-term Hatha yoga practitioners have better cognitive abilities compared to the control group in certain aspects of cognitive functions. Further physiological and psychological variables need to be examined in order to highlight the correlation between yoga intervention and cognitive performance.
Non‐Waste‐Wachsschalungen: Neuartige Präzisionsschalungen aus recycelbaren Industriewachsen

Die heutigen Möglichkeiten, im Stahlbetonbau komplexe Freiformen, geschwungene Wandungen und filigrane Details zu realisieren, bedingen Schalungstechnologien, die diesen Entwicklungen gerecht werden. Hohe Präzision bei maximaler Formfreiheit ist dabei ein wesentliches Anforderungskriterium für den Schalungsbau der neuen, sogenannten Freiformarchitekturen. Die Voraussetzungen für die Formfreiheit sind digitale 3D‐Planungs‐ und Fertigungstechnologien, mit deren Hilfe Schalungen mit hoher Präzision und beliebigen Freiheitsgraden entworfen und gefertigt werden. Der vorliegende Beitrag beschreibt einen Forschungsansatz, in dem Industriewachse als Schalungsmaterialien verwendet werden. Diese stellen durch die Wiederverwendbarkeit der Wachse einen ökonomischen und ökologischen Fertigungsprozess für individuelle Beton‐Freiformen dar.
C5a Receptor Oligomerization I. DISULFIDE TRAPPING REVEALS OLIGOMERS AND POTENTIAL CONTACT SURFACES IN A G PROTEIN-COUPLED RECEPTOR*

G protein-coupled receptors (GPCRs), stimulated by hormones and sensory stimuli, act as molecular switches to relay activation to heterotrimeric G proteins. Recent studies suggest that GPCRs form dimeric or oligomeric structures, a phenomenon that has long been established for growth factor receptors. The elucidation of the domains of GPCRs that mediate receptor association is of critical importance for understanding the function of GPCR oligomers. Using a disulfide-trapping strategy to probe the intermolecular contact surfaces, we demonstrate cross-linking of C5a receptors in membranes prepared from both human neutrophils and stably transfected mammalian cells that is mediated by a cysteine in the second intracellular loop. To explore other surfaces that might be involved in the oligomerization of C5a receptors, we constructed receptors with individual cysteines in other intracellular regions. C5a receptors with a cysteine in the first intracellular loop or the carboxyl terminus displayed the fastest kinetics of dimer formation, whereas an intracellular loop 3 cysteine displayed minimal cross-linking. Since the rate of disulfide trapping reflects the proximity of sulfhydryl groups, assuming similar accessibility and flexibility, these results imply a symmetric dimer interface that may involve either transmembrane helices 1 and 2 or helix 4. However, neither model can account for the ability of the native cysteine in the second intracellular loop to mediate efficient cross-linking. Based on these observations, we propose that C5a receptors form higher
Pulse-duration dependence of laser-induced modifications inside silicon

: The advent of ultrafast infrared lasers provides a unique opportunity for direct fabrication of three-dimensional silicon microdevices. However, strong nonlinearities prevent access to modiﬁcation regimes in narrow gap materials with the shortest laser pulses. In contrary to surface experiments for which one can always deﬁne an energy threshold to initiate modiﬁcations, we establish that some other threshold conditions inevitably apply on the pulse duration and the numerical aperture for focusing. In an experiment where we can vary continuously the pulse duration from 4 to 21 ps, we show that a minimum duration of 5.4 ps and a focusing numerical aperture of 0.85 are required to successfully initiate modiﬁcations. Below and above thresholds, we investigate the pulse duration dependence of the conditions applied in matter. Despite a modest pulse duration dependence of the energy threshold in the tested range, we found that all pulse durations are not equally performing to achieve highly reproducible modiﬁcations. Taken together with previous reports in the femtosecond and nanosecond regimes, this provides important guidelines on the appropriate conditions for internal structuring of silicon.
A MINIATURIZATION OF MICROSTRIP ANTENNA USING NEGATIVE PERMITIVITY METAMATERIAL BASED ON CSRR-LOADED GROUNDFOR WLAN APPLICATIONS

A microstrip antenna using negative permittivity me tamaterial based on complementary split ring resonator (CSRR)-loaded ground has been investigated in order to miniaturize the size and improve the antenna characteristics. The antenn as are designed on FR4 material and simulated results are provided by HFSS software. Th metamaterial antenna is reduced 77 % the antenna size compared to the normal microstrip ante nna. Furthermore, compared with the normal microstrip antenna, the antenna characterist ics of the metamaterial antenna are improved significantly. The proposed metamaterial antenna ac hieves the antenna resonate at 2.45 GHz, the gain of higher than 6.5 dB and the bandwidth of 110 MHz through the whole WLAN band. The obtained results indicate that the proposed antenna is a good candidate for WLAN applications.
Presensitized Rats Long-Term Survival of Hamster Hearts in

We transplanted hamster hearts into rats that had been sensitized to hamster cardiac grafts 5 days earlier as a model for discordant xenotransplantation. Sensitized rats had high serum levels of elicited anti-donor IgM and IgG that caused hyperacute rejection. Transient complement inhibition with cobra venom factor (CVF) plus daily and continuing cyclosporin A (CyA) prevented hyperacute rejection. However, grafts underwent delayed xenograft rejection (DXR). DXR involved IgG and associated Ab-dependent cell-mediated rejection, because depletion of IgG or Ab-dependent cell-mediated rejection-associated effector cells prolonged graft survival and the serum-mediated Ab-dependent cell-mediated cytotoxicity in vitro. Blood exchange in combination with CVF/CyA treatment dramatically decreased the level of preexisting Abs, but DXR still occurred in association with the return of Abs. Splenectomy and cyclophosphamide acted synergistically to delay Ab return, and when combined with blood exchange/ CVF/CyA facilitated long-term survival of grafts. These grafts survived in the presence of anti-donor IgM, IgG, and complement that precipitated rejection of naive hearts, indicating that accommodation (survival in the presence of anti-graft Abs and complement) had occurred. We attribute the long-term survival to the removal of preexisting anti-donor Abs and therapy that attenuated the rate of Ab return. Under such conditions, the surviving hearts showed expression in endothelial cells and smooth muscle cells of protective genes and an intragraft Th2 immune response. Th2 responses and protective genes are associated with resistance to IgM- and IgG-mediated, complement-dependent and -independent forms of rejection. The Journal of Immunology, 2000, 164: 4883–4892.
equations modeling. Inovação em pequenas e médias empresas: a influência da capacidade absortiva Innovation in small and medium enterprises: the influence of

Estruturais.  ABSTRACT This study examined the influence of the elements that make up the absorptive capacity (AC) dimensions on the innovation capacity (IC) of small and medium enterprises (SMEs). The research took place through a survey with questionnaires applied to 309 SMEs. We used the structural equations modeling technique (SEM) to analyze the data. The results showed that the dimensions of potential absorptive capacity (PACAP) and realized absorptive capacity (RACAP) have positive but distinct effects on the IC of SMEs. However, the impact on IC increases when the dimensions of the AC are evaluated in a multidimensional and individual manner. The study contributed theoretically by proving the multidimensionality of the MC construct in the universe of SMEs. As a managerial contribution, it is evident that RMCAP has a greater influence on the IC of SMEs, which proves the importance of managers/owners developing routines that enhance knowledge transformation
Exploring the effect of group polarisation on perceived invulnerability in general aviation pilots : a thesis presented in partial fulfilment of the requirements for the degree of Master of Aviation at Massey University

Although both perceived invulnerability and group polarisation are well known psychological phenomena, there has not been any research conducted to examine the effect of group polarisation on the level of perceived invulnerability amongst general aviation pilots. Two studies were conducted to measure the level of perceived invulnerability amongst general aviation pilots and to test whether the level of perceived invulnerability was affected due to group polarisation. The first study tested 34 pilots. Although the majority of the pilots exhibited perceived invulnerability, there was no evidence suggesting that low level group interaction induced group polarisation leading to an increase in individual's level of perceived invulnerability. The second study examined 78 pilots. Although the majority of the participants displayed perceived invulnerability, there was no evidence suggesting that high level group interaction resulted in group polarisation leading to an increase in individual's level of perceived invulnerability. There was no evidence that the two experimental manipulations (low group interaction and high group interaction) differed in effectiveness, as the effect size between studies I and II did not significantly differ. Although it is of some concern to general aviation safety that the majority of the pilots in both studies exhibited perceived invulnerability, the level of perceived invulnerability does not appear to be increased by a group polarisation effect. The latter finding is consistent with safe operations, having found no evidence that multi-crew operations lead to increased levels of perceived invulnerability. In addition to the implication of the current findings, limitations of the present study, possible areas for further research and recommendations are presented.
Reading Gigs Dialectically

With gig-based sex work as its analytical lens, this article argues that narratives about the crisis of gigification miss workers’ exits from non-gig employment. It advocates taking gig workers seriously when they say they prefer gigified hustling to clocking in for a middling wage. Gig work’s autonomy, limited as it is, can make the workday materially better. And the platform is not necessarily more powerful, or better able to forge false consciousness, than the cubicle farm or the assembly line. Grounded in sex workers’ critical engagements with the gig economy, the article finds workers armed with sharp class analyses who use gig economies to wrest control over their conditions of work. Their efforts produce uneven ends, but the tactics they deploy and the politics that inform them invite a rethinking of gigification and its stakes for twenty-first-century anti-capitalist struggle.
Collective occupations and nature: Impacts of the coloniality of nature on rural and fishing communities in Chile

ABSTRACT This manuscript is a reflection about existing relationships among the domination processes of capitalism/colonialism/patriarchy and two collective occupations that take place in the Bio Bio Region, Chile. The first of these occupations is artisanal fishing in Tumbes Cove and the second is the harvesting of medicinal plants in the locality of Manco. Specifically, an attempt is made to discuss the impacts of the coloniality of nature and the actual possibilities for resistance provided by these collective occupations. For this purpose, a desk research with a decolonial perspective was conducted, using as analytical axes the categories of extractivism, technologization, and scientification, which correspond to the domination mechanisms of nature. The findings suggest that collective occupations are versatile, as in some cases this capacity produces decomposition and, in others, a naïve re-existence. The powers and mechanisms triggered by these responses on different collective occupations is a field that needs further study in order to formulate critical and transformative knowledge in occupational science, as well as the possibility of creating counterhegemonic practices for communities to resist the power exerted by domination processes. This article aims to enhance the relationship among occupations and nature, as well as the idea that collective occupations are forms of resistance and re-existence facing patriarchal-colonial-capitalism, thus contributing to decolonizing practices informed by occupational science.

An MOR Algorithm Based on the Immittance Zero and Pole Eigenvectors for Fast FEM Simulations of Two-Port Microwave Structures

The aim of this article is to present a novel model-order reduction (MOR) algorithm for fast finite-element frequency-domain simulations of microwave two-port structures. The projection basis used to construct the reduced-order model (ROM) comprises two sets: singular vectors and regular vectors. The first set is composed of the eigenvectors associated with the poles of the finite-element method (FEM) state-space system, while the second one is made up from the eigenvectors corresponding to the zeros of the diagonal elements of the matrix-valued immittance transfer function. Importantly, just one LU factorization of the FEM system is required to construct the projection basis during the reduction process, due to the application of a new formulation based on the Schur complement. The sets of eigenvectors that are used in the basis are independent of one another, which makes the new technique better suited for parallel computing compared with previously developed methods, which are sequential in nature. The reliability and accuracy of the proposed scheme are compared with that of the standard MOR technique, namely, the reduced-basis method (RBM), and verified through the analysis of three microwave structures: an eighth-order dual-mode waveguide filter, a dielectric resonator filter, and a folded waveguide filter.
Strength and durability analysis of a flat spring at vibro-impact loadings

Volodymyr Gursky, Igor Kuzio We present the scheme of realization of a vibro­impact system with one flat spring and locally focused mass. The means of implementation of asymmetric piecewise linear elastic characteristic is the use of two intermediate cylindrical supports. We calculated the bending and contact stresses that take into account the asymmetry of change in the elastic characteristic and instantaneous displacement of the local mass. The parametric dependency is taken into account of the contact rigidity between the cylindrical support and the flat spring on the displacement of the local mass. This is carried out in order to assess in the course of dynamic analysis the stressed state of a flat spring under conditions of implementation of elastic characteristic. The contact rigidity is taken into account through the change in own oscillations frequency of the spring. We numerically solved the dynamic problem and obtained the ratio between kinematic characteristics (displacement and acceleration) and parameters of the stressed state (bending and contact stresses). The contact stresses are nonlinearly dependent on displacement, the bending –linearly. The strength margin factors by the stresses were defined, as well as the equivalent strength margin factor and the lifetime of the rod as the function of effort of perturbation. The equivalent strength margin factor takes into account the joint action of bending asymmetric and contact stresses. The obtained formulas realize the method of analysis of the stressed state under conditions of vibro­impact loadings. The method may be successfully applied in the course of design and synthesis of resonant vibro­impact systems and modes.
Distributed Radar-based Human Activity Recognition using Vision Transformer and CNNs

The feasibility of classifying human activities measured by a distributed ultra-wideband (UWB) radar system using Range-Doppler (RD) images as the input to classifiers is investigated. Kinematic characteristics of different human activities are expected to be captured in high-resolution range-Doppler images measured by UWB radars. To construct the dataset, 5 distributed monostatic Humatics P410 radars are used to record 15 participants performing 9 activities in arbitrary directions along a designated trajectory. For the first time a convolution-free neural network based on the novel multi-head attention mechanism (the Vision Transformer architecture) is adopted as the classifier, attaining an accuracy of 76.5 %. A comparison between Vision Transformer and more conventional CNN-based architectures, such as ResNet and AlexNet, is also conducted. The robustness of Vision Transformer and the other networks against unseen participants is also validated by testing via Leave One Participant Out validation.
SwinT-Unet: Hybrid architecture for Medical Image Segmentation Based on Swin transformer block and Dual-Scale Information

The fast development of Convolution Neural Networks (CNN) based on U-shaped architecture has shown innovative improvements in the fields of image segmentation. However, these approaches cannot learn global information in images due to the local aspect of the convolution operation. This paper deals with designing a hybrid method of medical image segmentation. Taking advantage of Shifted windows (Swin) transformer block to extract fine-grained features and the Transformer Interactive Fusion (TIF) module to create a fusion between features of different scales, the proposed approach consists of a dual-Scale encoder–Swin transformer U-shaped architecture (SwinT-Unet). The effectiveness of this method has been evaluated on the Synapse multi-organ CT dataset. The suggested segmentation demonstrated more efficiency than the results of some other current methods.
