Heavy states in 3d gravity and 2d CFT
Authors: Grabovsky David 
Published: August 2024

Abstract
We discuss correlators of light fields in heavy states in AdS3 gravity and holographic 2d CFTs. In the bulk, the propagator of free fields in AdS backgrounds containing a conical defect or a BTZ black hole can be obtained by solving a wave equation, as well as by the method of images. On the boundary, these geometries are sourced by heavy operator insertions, and the propagator is dual to a heavy-light (HHLL) correlator. By matching its expansion in Virasoro blocks to our bulk results, we determine the OPE coefficients of all contributing states in both the s and t channels. In the s channel, these states are excitations of the light field on top of the heavy state, and their OPE coefficients are the amplitudes to create them. The t-channel OPE is dominated by the Virasoro vacuum block, but there is also an infinite family of light two-particle states that contribute to the correlator. The OPE coefficients that couple these states to heavy operators represent their expectation values in heavy backgrounds. We determine them exactly, derive their asymptotic form at large twist, and discuss their behavior near and above the BTZ threshold, where they become thermal one-point functions.
Spin-(s, j) projectors and gauge-invariant spin-s actions in maximally symmetric backgrounds
Authors: Hutchings Daniel , Ponds Michael 
Published: August 2024

Abstract
Given a maximally symmetric d-dimensional background with isometry algebra $$ \mathfrak{g} $$
g
, a symmetric and traceless rank-s field ϕa(s) satisfying the massive Klein-Gordon equation furnishes a collection of massive $$ \mathfrak{g} $$
g
-representations with spins j ∈ {0, 1, · · · , s}. In this paper we construct the spin-(s, j) projectors, which are operators that isolate the part of ϕa(s) that furnishes the representation from this collection carrying spin j. In the case of an (anti-)de Sitter ((A)dSd) background, we find that the poles of the projectors encode information about (partially-)massless representations, in agreement with observations made earlier in d = 3, 4. We then use these projectors to facilitate a systematic derivation of two-derivative actions with a propagating massless spin-s mode. In addition to reproducing the massless spin-s Fronsdal action, this analysis generates new actions possessing higher-depth gauge symmetry. In (A)dSd we also derive the action for a partially-massless spin-s depth-t field with 1 ≤ t ≤ s. The latter utilises the minimum number of auxiliary fields, and corresponds to the action originally proposed by Zinoviev after gauging away all Stückelberg fields. Some higher-derivative actions are also presented, and in d = 3 are used to construct (i) generalised higher-spin Cotton tensors in (A)dS3; and (ii) topologically-massive actions with higher-depth gauge symmetry. Finally, in four-dimensional $$ \mathcal{N} $$
N
= 1 Minkowski superspace, we provide closed-form expressions for the analogous superprojectors.
The effect of wood particles polyesterification with sorbitol and citric acid on the properties of particleboard produced with the use of PF/pMDI adhesive

AbstractThis study investigated the effect of pine particle polyesterification with the mixture of sorbitol and citric acid (SCA) on the properties of particleboard bonded with the PF/pMDI hybrid resin. The use of SCA with a concentration of 35% contributed to improvement in the internal bond of the particleboards, their water resistance and dimensional stability. However, lowering the concentration to 25% resulted in a deterioration of the properties of produced materials. The effect of different loadings of pMDI in the PF/pMDI resin (0%, 5%, 15%, 25%) was also investigated and the outcomes showed a positive effect of the share of 15% and 25%. Furthermore, boards made of treated particles were characterized by slightly better flammable properties (lower mass loss, flashing point temperature and delayed ignition), and the visibility of the effect increased with the increase in the concentration of the impregnate. The results also indicate that the introduction of pMDI may also influence the ignition of the board.
Import shock and local labour market outcomes: A Sino-Indian case study
Authors: Shi Feiyang 
Published: August 2024

Abstract
Focusing on Sino-Indian trade, this paper uses detailed district-level data, exploits India’s drastic increase in imports from China since 2001, and uses the instrumental variables approach to examine the impact of trade shock on the local labour market outcomes. Through a matching procedure, the geographical coverage of the paper is significantly improved compared with prior studies. The range of labour market outcome variables examined is also much broader, including wage, residual wage fluctuation, employment, unemployment and underemployment as shares of the working-age population. The paper finds that the import competition from China had a negative impact on the districts’ average wages but a positive impact on districts’ shares of employment. Moreover, the paper allows heterogeneous effects across consumption, age, gender, occupation and industrial groups. The results confirm that the effect of import shock is not uniformly distributed within the districts. Rather, it varies with respect to specific socio-economic characteristics. The wage effect, for example, is positive for those from the lower consumption basket.

AbstractPlants thrive in diverse environments, where root-microbe interactions play a pivotal role. Date palm (Phoenix dactylifera L.), with its genetic diversity and resilience, is an ideal model for studying microbial adaptation to different genotypes and stresses. This study aimed to analyze the bacterial and fungal communities associated with traditional date palm cultivars and the widely cultivated “Deglet Nour” were explored using metabarcoding approaches. The microbial diversity analysis identified a rich community with 13,189 bacterial and 6442 fungal Amplicon Sequence Variants (ASVs). Actinobacteriota, Proteobacteria, and Bacteroidota dominated bacterial communities, while Ascomycota dominated fungal communities. Analysis of the microbial community revealed the emergence of two distinct clusters correlating with specific date palm cultivars, but fungal communities showed higher sensitivity to date palm genotype variations compared to bacterial communities. The commercial cultivar “Deglet Nour” exhibited a unique microbial composition enriched in pathogenic fungal taxa, which was correlated with its genetic distance. Overall, our study contributes to understanding the complex interactions between date palm genotypes and soil microbiota, highlighting the genotype role in microbial community structure, particularly among fungi. These findings suggest correlations between date palm genotype, stress tolerance, and microbial assembly, with implications for plant health and resilience. Further research is needed to elucidate genotype-specific microbial interactions and their role in enhancing plant resilience to environmental stresses.

AbstractSemi-natural grasslands (SNGLs) in Estonia are threatened by abandonment. This threat is leading to concerns about the degradation of biodiversity within grassland communities. Despite the high relevance of economic incentives in this context, how such incentives influence land managers’ decision-making regarding the agricultural use of SNGLs has not been investigated. To obtain its socio-ecological implications for policy-making, we developed regionally specific agricultural scenarios (compensation payments, livestock capacity, hey export, and bioenergy production) and an interdisciplinary modelling approach that made it possible to simulate agricultural land use changes through land managers' responses to varied economic conditions. Through this approach, we found that some economic factors hampered the use of SNGLs: the moderate profitability of beef production, labour shortages, and the relatively high profitability of mulching. We observed a positive relationship between SNGLs and habitat suitability for breeding and feeding birds. However, due to the high maintenance costs of SNGLs, the modelling results indicated that increasing the use of SNGLs through public budgets caused crowding-out effects, i.e., the deteriorating market integration of regional agriculture. This study emphasises the need for policy measures aimed at cost-effective, labour-efficient management practices for SNGLs.
Pre-hospital heparin is not associated with infarct vessel patency and mortality in ST-segment elevation myocardial infarction patients with out-of-hospital cardiac arrest

Published: August 2024

Abstract
Background
Pre-hospital heparin administration has been reported to improve prognosis in patients with out-of-hospital cardiac arrest (OHCA). This beneficial effect may be limited to the subgroup of ST-segment elevation myocardial infarction (STEMI) patients.

Methods
To assess the impact of pre-hospital heparin loading on TIMI (Thrombolysis in Myocardial Infarction) flow grade and mortality in STEMI patients with OHCA, we analyzed data from 2,566 consecutive patients from two hospitals participating in the prospective Feedback Intervention and Treatment Times in ST-segment Elevation Myocardial Infarction (FITT-STEMI) trial.

Results
In 394 participants with OHCA, 272 (69%) received heparin from the emergency medical service (EMS). Collapse witnessed by EMS (odds ratio (OR) = 3.53, 95%-confidence interval (CI) = 1.54–8.09; p = 0.003) and pre-hospital ECG recording (OR = 3.32, 95% CI = 1.06–10.35; p = 0.039) were identified as parameters significantly associated with pre-hospital heparin use. In univariate analysis, in-hospital mortality was lower in the group receiving heparin in the pre-hospital setting (26.8% vs. 42.6%, p = 0.002). However, in a regression model, pre-hospital heparin use was no longer a significant predictor of mortality (OR = 0.992; p = 0.981). Patency of the infarct artery prior to coronary revascularization, as measured by TIMI flow grade, was not associated with pre-hospital administration of heparin in OHCA patients (OR = 0.840; p = 0.724).

Conclusions
In STEMI patients with OHCA, pre-hospital use of heparin is neither associated with improved early patency of the infarct artery nor with a better prognosis. Our results do not support the assumption of a positive effect of heparin administration in the pre-hospital treatment phase in STEMI patients with OHCA.

Discrepancies in dynamic yield stress measurements of cement pastes
Authors: Dhar Subhransu , Liberto Teresa , Barentin Catherine , Divoux Thibaut , Robisson Agathe 
Published: August 2024

Abstract
The dynamic yield stress associated with the flow cessation of cement pastes is measured using a rheometer equipped with various shear geometries such as vane, helical, sandblasted co-axial cylinders, and serrated parallel plates, as well as with the mini-cone spread test. Discrepancies in yield stress values are observed for cement pastes at various volume fractions, with one to two orders of magnitude difference between vane, helical and mini-cone spread measurements on the one hand, and co-axial cylinder and parallel plate measurements on the other hand. To understand this discrepancy, the flow profile of a cement paste in the parallel-plate geometry is investigated with a high-speed camera, revealing the rapid formation of an un-sheared band near the static bottom plate. The width of this band depends upon the rotational velocity of the top plate, and upon the shear time. Recalculation of shear stress shows that the reduced sheared gap alone cannot explain the low measured yield stress. Further exploration suggests the formation of zones with lower particle content, possibly linked to cement particle sedimentation. Here, we argue that the complex nature of cement pastes, composed of negatively buoyant non-Brownian particles with attractive interactions due to highly charged nano-size hydration products, accounts for their complex rheological behavior.

Abstract
Introduction
Amidst the rising number of cancer survivors and personnel shortages, optimisation of follow-up strategies is imperative, especially since intensive follow-up does not lead to survival benefits. Understanding patient preferences and identifying the associated patient profiles is crucial. Coping style may be a key determinant in achieving this. Our study aims to evaluate preferences, identify coping styles and their associated factors, and explore the association between coping style and patients’ preferences in colorectal cancer (CRC) follow-up.

Methods
In a prospective multicentre implementation study, patients completed the Threatening Medical Situations Inventory (TMSI) to determine their coping style. Simultaneously patients choose their follow-up preferences for the CRC trajectory regarding frequency of tumour marker determination, location of blood sampling, and manner of contact.

Results
A total of 188 patients completed the TMSI questionnaire after inclusion. A more intensive follow-up was preferred by 71.5% of patients. Of all patients, 52.0% had a coping style classified as ‘blunting’ and 34.0% as ‘monitoring’. Variables such as a younger age, female gender, higher educational level, and lower ASA scores were associated with having higher monitoring scores. However, there were no significant associations between follow-up preferences and patients’ coping styles.

Conclusion
This study suggests that none of the provided options in a patient-led follow-up are unsuitable for patients who underwent curative surgery for primary CRC, based on coping style determined at baseline. Low-intensity surveillance after curative resection of CRC may, therefore, be suitable for a wide range of patients independent of coping styles.

AbstractBreast milk is the most appropriate food for an infant in the first months of life - it provides the essential nutrients required for proper growth, with breast milk oligosaccharides (HMOs) being the third most abundant component. HMO concentrations vary based on factors like lactation stage and maternal health. They play crucial roles in infant health, acting as prebiotics, antimicrobials, and immune modulators. Analytical methods like capillary electrophoresis and liquid chromatography are the most often used in HMOs qualitative and quantitative analysis. Continuing research aims to enhance analytical techniques for comprehensive HMOs analysis, this work presents the development of a capillary electrophoresis method with laser-induced fluorescence detection along with derivatization and solid-phase extraction steps for the characterisation of major oligosaccharides in colostrum samples. Validation parameters, such as linearity (0.9949–0.9989), limits of detection (5.49–16.40 ng cm−3) and quantification (18.30–54.67 ng cm−3), intra- and inter-day precision (2.41–9.78% and 1.27—14.5%, respectively), trueness (− 8.4 to − 2.0%), and recovery (70.02–113.5%) and repeatability (2.22–10.58%) for solid-phase extraction stage were assessed. The method was evaluated using RGB additive colour model regarding the analytical and practical effectiveness and greenness of the method (achieving a brilliance score of 67.1%). Moreover, the developed method was successfully applied to determine three oligosaccharides (DSLNT, 3’SL, and 6’SL) in colostrum samples. Considering its effectiveness, the method has promise for this type of application.

An experimental and numerical study of the influence of the additive manufacturing process in packing properties of particles: the printed shape matters

Published: August 2024

AbstractInvestigations into the various properties of granular matter composed of particles with defined shapes have gained increasing attention. Additive manufacturing, with its freedom of shape and rapid prototyping capabilities, has significantly contributed to these studies. However, this technique may introduce defects in the manufactured particles, which can significantly affect the properties of granular materials. The extent of these defects on particles of different shapes is investigated here. Particles of various shapes (cube, octahedron, quatropod, stellated octahedron, tetrahedron, and tetrapod) were manufactured and subsequently imaged using micro-Computed Tomography. The surface roughness, solidity, and convexity of the particles were quantified. Discrete element simulations of granular bed porosity, utilizing both idealized and real particle shapes, were conducted with different surface mesh resolutions and frictional parameters. A clear influence of the manufacturing process on the packing properties of 3D printed particles was identified. This influence is not uniform across all shapes and is directly correlated with the particle convexity. For numerical simulations, a shape-dependent correction of particle density and surface characteristics are imperative for each shape under consideration, despite the fact that the particles were manufactured using the same technique and material.

Constructing bacterial cellulose and its composites: regulating treatments towards applications
Authors: Wang Jing , Li Caiyun , Tang Youhong 
Published: August 2024

AbstractThe production and advanced treatments of bacterial cellulose (BC) and its composites have garnered increased attention in the past decades. As a biodegradable polymer, BC possesses remarkable purity, super-fine nanonetwork structure, biocompatibility, and excellent mechanical properties, which could satisfy the most needs of application areas. The comprehensive knowledge of different BC treatment methods is critical to property modification through composite formation towards multifunctional applications. In this review, we summarised three BC treatment methods and relevant functional composite construction processes, especially the emerging breaking-refactoring methods. It is known that the structure-property-application relationship of BC composites is tightly linked. The successful development of multifunctional BC-based composites will rely on good sustainability and exploration of BC-based composite preparation technology. Applications of BC and its composites based on those treatment methods are reviewed. The properties and characteristics underlying these approaches to BC and its composite applications are also discussed here.

AbstractThis study uses Texas’s 2017 integration of the state disability and mental health agencies as a case study, combining interviews with Texas agency and advocacy organization leaders to examine perceptions of agency integration and augmented synthetic control analyses of 2014–2020 Medical Expenditure Panel Survey to examine impacts on mental health service use among individuals with co-occurring cognitive disabilities (including intellectual and developmental disabilities) and mental health conditions. Interviewees described the intensive process of agency integration and identified primarily positive (e.g., decreased administrative burden) impacts of integration. Quantitative analyses indicated no effects of integration on receipt of mental health-related services among people with co-occurring conditions. While leaders identified some potentially beneficial impacts of state agency integration, the limited impact of integration beyond the agency suggests that interventions at multiple levels of the service system, including those targeting providers, are needed to better meet the mental health service needs for this population.
The accessibility of digital technologies for people with visual impairment and blindness: a scoping review

Published: August 2024

AbstractThis scoping review aimed to improve the understanding of important factors in digital accessibility for people with visual impairment and blindness, focusing on the first-hand experiences and challenges faced by this target group while using digital technologies. Keywords related to ‘digital technologies,’ ‘accessibility,’ ‘visual impairment,’ and ‘blindness’ were used in searching two databases (n = 683), with additional articles identified by means of manual searches (n = 60). Two reviewers independently screened the titles and abstracts to select 97 articles for full-text screening, of which 49 articles met the inclusion criteria and were selected for review based on the WCAG guidelines, highlighting details for consideration and improvement of the guidelines. The analysis revealed that users suffered from inaccessibility in several ways. For example, many applications or websites are developed for sighted users, where information is communicated through visual content without providing alternatives for assistive technology users. In addition, the lack of keyboard accessibility, shortcuts, or compatibility with different assistive technologies remains a consistent challenge. Furthermore, it was highlighted that simple accessibility measures are not followed adequately or consistently, such as providing alternative text for images or labels for links and buttons. This review highlighted the challenges and consequences of the inaccessibility of digital technologies, providing a detailed explanation regarding the elements that should be considered in the development of digital technologies. It is recommended that people with disabilities should be involved in the design of technology and its accessibility assessment.
