Effects of blowing upon dynamic stability of blunt nosed re entry vehicles pitching in hypersonic flow
Authors: Khalid M. , Juhany K.A. 
Published: August 2023

AbstractBlowing is often used to alleviate the intense heating rates on blunt noses of hypersonic vehicles. This flow efflux at the leading edge transforms the flow field in the blunt-nose regions with implications on the dynamic stability of the vehicles. As a demonstrative exercise, the flow fields past blunt-nosed and truncated-nosed conical bodies under blowing and no-blowing conditions were perturbed to obtain the unsteady effects using the shock expansion method to recover the unsteady pressure coefficient. Static and pitching moment derivatives were then duly obtained by integrating the differential of the unsteady pressure coefficient with respect to the pitch angle (α) or the pitch rate (
$\dot \theta $
) together with the moment arm with reference to the centre of gravity. The results obtained for blunt-nose and truncated conical bodies show a noticeable drop in dynamic stability. Even when the flow is transformed from a tangential blowing at the shoulder of the blunt-nosed vehicle shows some degradation in dynamic stability.

Authors: McKeown Monica D. , Crighton Eric , Mestre Tiago A. ,   iCARE-PD consortium
Published: August 2023

ABSTRACT:Background:Parkinson’s disease (PD) is a common chronic neurodegenerative condition. As a result of the COVID-19 pandemic, healthcare provision faced challenges worldwide. We aimed to explore how the COVID-19 pandemic changed healthcare experiences for people living with Parkinson’s disease (PwP) in Canada.Methods:We conducted a national cross-sectional online survey about healthcare access for PwP in 2020. Participants (n = 298) were recruited through Parkinson Canada, the national patient association and its provincial partners, that advertised the study in a monthly newsletter. We used descriptive statistics and multivariate regression modelling to test associations of interest. A P < 0.05 was deemed statistically significant.Results:During the COVID-19 pandemic, PwP reported greater difficulty obtaining PD-related healthcare services and lesser satisfaction with healthcare provision compared to pre-pandemic experiences. Dissatisfaction with care was associated with the presence of barriers to access services, a lack of confidence in accessing services remotely, pre-pandemic care dissatisfaction, and difficulty in obtaining care during the COVID-19 pandemic. Unmet care needs were associated with a lack of confidence in accessing services remotely, dissatisfaction with pre-pandemic care, difficulty obtaining pre-pandemic care, and communication challenges.Conclusion:Our results suggest that healthcare experiences for PwP significantly changed during the COVID-19 pandemic, with challenges in access to virtual care. Poorer pre-pandemic care experiences were amplified during the pandemic.
Disjoint hypercyclicity, Sidon sets and weakly mixing operators
Authors: CARDECCIA RODRIGO 
Published: August 2023

AbstractWe prove that a finite set of natural numbers J satisfies that
$J\cup \{0\}$
is not Sidon if and only if for any operator T, the disjoint hypercyclicity of
$\{T^j:j\in J\}$
implies that T is weakly mixing. As an application we show the existence of a non-weakly mixing operator T such that
$T\oplus T^2\oplus\cdots \oplus T^n$
is hypercyclic for every n.
Snap-through dynamics of a buckled flexible filament in a uniform flow
Authors: Mao Qian , Liu Yingzheng , Sung Hyung Jin 
Published: August 2023

The flow-induced snap-through dynamics of a buckled flexible filament was explored using the penalty immersed boundary method. The effects of the filament length, bending rigidity and Reynolds number on the mode transition were systematically examined. Three different modes were observed when the aforementioned parameters were varied: an equilibrium mode, a streamwise oscillation mode and a snap-through oscillation mode. Two mode transitions occurred when the bending rigidity was lowered and the length and Reynolds number were increased: a direct transition from the equilibrium mode to the snap-through oscillation mode and the successive appearance of the three modes. An increase in transverse fluid force induced the snap-through oscillation mode. A vortex-induced vibration and a self-excited vibration occurred in the streamwise oscillation mode and the snap-through oscillation mode, respectively. A wake pattern of 2S appeared in the streamwise oscillation mode, and a pattern of 2S + 2P appeared in the snap-through oscillation mode. A hysteresis was observed near the critical Reynolds number. The hysteresis loop increased in magnitude with increasing bending rigidity. The greater energy harvesting was achieved by the larger deflection and the higher strain energy. We found that most of the strain energy was concentrated in the last half of the filament.
The spectral eigenmatrix problems of planar self-affine measures with four digits
Authors: Liu Jing-Cheng , Tang Min-Wei , Wu Sha 
Published: August 2023

AbstractGiven a Borel probability measure µ on $\mathbb{R}^n$ and a real matrix $R\in M_n(\mathbb{R})$. We call R a spectral eigenmatrix of the measure µ if there exists a countable set $\Lambda\subset \mathbb{R}^n$ such that the sets $E_\Lambda=\big\{{\rm e}^{2\pi i \langle\lambda,x\rangle}:\lambda\in \Lambda\big\}$ and $E_{R\Lambda}=\big\{{\rm e}^{2\pi i \langle R\lambda,x\rangle}:\lambda\in \Lambda\big\}$ are both orthonormal bases for the Hilbert space $L^2(\mu)$. In this paper, we study the structure of spectral eigenmatrix of the planar self-affine measure $\mu_{M,D}$ generated by an expanding integer matrix $M\in M_2(2\mathbb{Z})$ and the four-elements digit set $D = \{(0,0)^t,(1,0)^t,(0,1)^t,(-1,-1)^t\}$. Some sufficient and/or necessary conditions for R to be a spectral eigenmatrix of $\mu_{M,D}$ are given.
‘The nation has conquered the state’: Arendtian insights on the internal contradictions of the nation-state
Authors: Verovšek Peter J. 
Published: August 2023

AbstractThe globalisation of political power into structures ‘above’ or ‘beyond’ the nation-state has increasingly been called into question as part of a ‘sovereigntist turn’ in contemporary politics. While such demands for local control by bounded peoples may be democratic, empirically they often also take a nationalist form. Building on Hannah Arendt’s analysis of how ‘the nation conquered the state’, I argue that the slippage from democratic to national sovereigntism is rooted in fundamental conceptual instabilities within the concept of the nation-state. Whereas the first term in this hyphenated construct favours certain individuals based on their ethnic background, the latter is a universal concept that demands the equal treatment of all. My basic thesis is that these internal contradictions help to explain the nationalist tendency in calls to return political power to the nation-state. I illustrate these points by drawing on examples from the ‘illiberal democracies’ of Central-Eastern Europe, focusing on Poland and Hungary.

Published: August 2023

SummaryInvasive species can have disastrous effects on the ecosystems they invade, requiring costly, labour-intensive mitigation. Public awareness campaigns are often used as a tool to reduce these species’ impacts. While heralded as useful and cost-effective, little evidence suggests that these campaigns contribute to meaningful biological outcomes. Furthermore, awareness campaigns are relatively understudied despite their usage as a common approach to mitigating invasive species. We conducted a literature review to assess publications that evaluated the efficacy of public awareness campaigns for managing invasive species. Out of 4382 papers initially extracted for analysis, we determined that 24 of them included studies conducted on awareness campaigns for invasive species. Four public awareness campaigns were deemed a ‘success’, and the other campaigns’ success was indeterminable due to study design. Our study revealed that inconsistencies in defined end points, unclear procedures and variability of campaigns contribute to there being insufficient evidence to determine the efficacy of public awareness campaigns. To evaluate the true efficacy of public awareness campaigns, we recommend that organizations conducting such campaigns implement rigorous and standardized assessments (e.g., Before–After Control–Impact designs or Bayesian analyses) that include measures of not just changes in the knowledge and behaviour of target audiences, but also relevant biological outcomes.
Prospering despite the adverse terms of emancipation? Accumulation of wealth by peasant farmers in the tsarist Russian province of Livonia, 1853–1913
Authors: Lust Kersti 
Published: August 2023

AbstractThe article addresses the issue of wealth accumulation by peasant farmers in the post-emancipation era in the Russian Baltic province of Livonia. The Baltic emancipation schemes stand out as the least beneficial for peasants as they set neither time limits nor land price levels, and the state government did not provide any credit to the purchasers of farms. However, in northern Livonia the nominal value of peasant farmers’ wealth grew as much as tenfold from 1850 to 1913. The study reveals that the advantages and disadvantages of high farm purchase prices should be considered in combination with other factors affecting agricultural growth. In the Baltic context, the large size of the farms, land consolidation, well-developed infrastructure, and the commercialisation of production helped the farm owners amass a relatively large amount of wealth within a generation. Technological improvement also contributed to the rise in productivity and wealth.

AbstractIntroduction:The Stop the Bleed campaign provided civilians with tourniquet application training and increased the demand for tourniquets among the general population, which led to the development of new commercially available devices. However, most widely available tourniquets have not undergone testing by regulatory bodies and their efficacy remains unknown.Study Objective:This study aimed to compare the efficacy and performance of Combat Application Tourniquets (CAT) versus uncertified tourniquets.Methods:This study compared 25 CAT with 50 commercially available “look-alike” tourniquets (LA-TQ) resembling the CAT. The CAT and the LA-TQ were compared for cost, size, and tested during one-hour and six-hour applications on a manikin’s leg. The outcomes were force applied, force variation during the application, and tourniquet rupture rate.Results:The LA-TQ were cheaper (US$6.07 versus US$27.19), shorter, and had higher inter-device variability than the CAT (90.1 [SE = 0.5] cm versus 94.5 [SE = 0.1] cm; P <.001). The CAT applied a significantly greater force during the initial application when compared to the LA-TQ (65 [SE = 3] N versus 14 [SE = 1] N; P <.001). While the initial application force was maintained for up to six hours in both groups, the CAT group applied an increased force during one-hour applications (group effect: F [1,73] = 105.65; P <.001) and during six-hour applications (group effect: F [1,12] = 9.79; P = .009). The rupture rate differed between the CAT and the LA-TQ (0% versus 4%).Conclusion:The LA-TQ applied a significantly lower force and had a higher rupture rate compared to the CAT, potentially affecting tourniquet performance in the context of public bleeding control. These findings warrant increased layperson education within the framework of the Stop the Bleed campaign and further investigations on the effectiveness of uncertified devices in real-world applications.
Product promotions in online supermarkets: prevalence of ‘High Fat Sugar Salt’ (HFSS) products and labelling characteristics
Authors: Wallis Lewis W , Moore Sally G 
Published: August 2023

AbstractObjective:To evaluate the prevalence of ‘High Fat Sugar Salt’ (HFSS) products and front-of-pack nutrition labelling (FOPNL) characteristics across promoted products in UK online supermarkets.Design:A cross-sectional survey conducted (December 2021–January 2022) on promoted products. Data on ingredients, nutritional composition and display of FOPNL were collected from product webpages. The UK’s Nutrient Profiling Model and Multiple Traffic Light criteria were used to determine HFSS status and possession of inherent red traffic lights (iRTL), respectively. Data analysis determined the prevalence (i.e. percentage of products of the total number of products sampled) of HFSS; FOPNL and possession of iRTL. Chi-squared tests explored associations between these.Setting:Three major UK online supermarket retailer websites.Participants:Product ‘multibuy’ and ‘entrance’ promotions, from selected product categories.Results:Among the sampled 625 promoted products, the prevalence of HFSS was greater in entrance (73 %) compared with multibuy (41 %) promotions (χ2 (1) = 34, P < 0·05), with variations in the former across retailers (49–92 %). The prevalence of HFSS products in multibuy promotions offered by two retailers varied by category (i.e. Confectionery 94–97 %, Yogurts 20–20 %, Soft Drinks 16–33 %, Ready Meals 1·4–18 %). Not all promoted products displayed FOPNL on webpages (70 %) or images (52 %). A number of iRTL were found to be possessed by both HFSS and non-HFSS-promoted products.Conclusions:Prior to the 2022 implementation of Regulations restricting these, HFSS products were promoted in online supermarkets with varying display of FOPNL and possession of iRTL. Findings support future policy evaluation and mandatory digital FOPNL.

AbstractObjectivesWithin the multidisciplinary team, there can sometimes be lack of clarity as to the specific different contributions of each of the psycho-social-spiritual professionals: social workers, psychologist, and spiritual caregivers. This study examined the content of their end-of-life conversations with patients.MethodsA total of 180 patients with terminal cancer received standard multidisciplinary care, including conversations with a social worker, psychologist, and spiritual caregiver. After each patient’s death, these professionals reported using a structured tool which content areas had arisen in their conversations with that patient.ResultsAcross all content areas, there were significant differences between social work and spiritual care. The difference between social work and psychology was slightly smaller but still quite large. Psychology and spiritual care were the most similar, though they still significantly differed in half the content areas. The differences persisted even among patients who spoke with more than 1 kind of professional. The 6 content areas examined proved to subdivide into 2 linked groups, where patients speaking about 1 were more likely to speak about the others. One group, “reflective” topics (inner and transpersonal resources, interpersonal relationships, one’s past, and end of life), included all those topics which arose more often with spiritual caregivers or psychologists. The second group, “decision-making” topics (medical coping and life changes), was comprised of those topics which arose most commonly with social workers, bridging between the medical and personal aspects of care and helping patients navigate their new physical, psychological, and social worlds.Significance of resultsThese findings help shed light on the differences, in practice, between patients’ conversations with social workers, psychologists, and spiritual caregivers and the roles these professionals are playing; can aid in formulating individualized care plans; and strengthen the working assumption that all 3 professions contribute in unique, complementary ways to improving patients’ and families’ well-being.

AbstractObjectivesThis study investigated the challenges and support needs of adults aged 75 and older during and after treatment for a blood cancer to aid targeted supportive resource development.MethodsAdults aged 75 and older with a blood cancer participated in in-depth, semi-structured interviews about challenges and unmet support needs. Participants recruited through The Leukemia & Lymphoma Society were (1) in treatment or previously in treatment for a blood cancer at age 75 or older and (2) living in the United States or its territories. A thematic analysis was conducted with findings compared between 2 groups: (1) chronic -living with a chronic blood cancer; (2) acute -living with an acute blood cancer or both an acute and chronic blood cancer.ResultsParticipants (n = 50) ranged from 75 to 91 years old. Both groups described similar experiences and identified 5 challenges and support needs: (1) socioemotional impact, (2) activities of daily living and instrumental activities of daily living (ADLs/iADLs), (3) uncertainty management, (4) treatment-related stressors, and (5) COVID-19-related strain. Properties for these themes illustrate challenges and support needs, with some differences between groups. For instance, those living with a chronic blood cancer highlighted financial strain with treatment-related stressors, while those with an acute blood cancer focused more on iADLs.Significance of resultsFindings inform an agenda for targeted resource development for older adults with a blood cancer nearing the end of the life span. Results demonstrate the need for supportive services and family communication interventions to help patients manage iADLs and navigate socioemotional needs and challenges.

AbstractContextDepression is common in individuals with cancer and pain, negatively impacts quality of life, treatment adherence, tumor progression, and survival.ObjectivesThe primary aims of this study were to (1) evaluate the validity of the Edmonton Symptom Assessment System’s depression (ESAS-D) for detecting major depressive disorder (MDD) as diagnosed by a psychiatrist and (2) identify the best cutoff for this purpose in a sample of cancer pain individuals. The secondary aim was to compare ESAS-D with another commonly used screening measure (Patient Health Questionnaire-2 [PHQ-2]) for classifying individuals as meeting or not meeting Diagnostic and Statistical Manual of Mental Disorders, Fifth Edition (DSM-5) criteria for depression.Methods49 cancer pain individuals completed the ESAS-D and PHQ-2 Within 2 weeks, a psychiatrist interviewed the participants and determined whether or not they met criteria for MDD based on the DSM-5.ResultsThe ESAS-D demonstrated acceptable accuracy and validity for classifying MDD. A cutoff of ≥2 was identified as being best able to balance sensitivity (85%) and specificity (76%) and had an overall accuracy of 79%. A receiver operating characteristic curve analysis showed an area under the curve (AUC) of 0.81 (95% confidence interval [CI]: 0.68–0.94). The ESAS-D also compared favorably with the modified Thai PHQ-2 (sensitivity, 75%; specificity, 72%; overall accuracy, 73%; AUC, 0.74 [95% CI: 0.59–0.88]) for identifying MDD individuals.ConclusionsThe ESAS-D showed acceptable sensitivity, specificity, and overall accuracy for screening for MDD in cancer and pain. It could therefore be used to screen for probable depression in this population.

Published: August 2023

Abstract
Co-active coping is a fundamental construct in organizational and work environments as it allows for the exploration of individual and group behaviors within organizations. The aim of this study was to develop a new scale called the Co-Active Coping Inventory in the Chilean context. The sample was comprised of 1,442 workers with an average age of 30.48 years (SD = 11.13). 55% were public-sector workers, 34.5% were workers in private commercial organizations, and 10.5% belonged to non-profit private organizations. Different exploratory factor analyses were performed, and the best exploratory model was verified with a confirmatory factor analysis. In addition, multiple linear regressions were used to analyze which dimensions of co-active coping helped predict workers’ burnout (emotional exhaustion, affective hardening, and personal fulfillment) and symptomatology (psychological and somatic). Based on the exploratory and confirmatory approach, the Co-Active Coping Inventory showed a good fit to a structure of five correlated factors (Reflective Action, Rash Action, Search for Spiritual Support, Search for Affective Support and Evasion), demonstrating measurement invariance in terms of sex and type of organization. The different domains of co-active coping explain between 20% (emotional exhaustion) and 41% (affective hardening) of occupational burnout and around 3–5% of workers’ symptomatology, with reflective action being the most important variable. These results indicate that the new scale has suitable psychometric properties; it can assess coping strategies in the Chilean organizational context in a reliable and valid way. These coping strategies have demonstrated certain importance in relation to organizational and clinical variables.
