Multipole expansion of gravitational waves: memory effects and Bondi aspects
Authors: Blanchet Luc , Compère Geoffrey , Faye Guillaume , Oliveri Roberto , Seraj Ali 
Published: July 2023

Abstract
In our previous work, we proposed an algorithm to transform the metric of an isolated matter source in the multipolar post-Minkowskian approximation in harmonic (de Donder) gauge to the Newman-Unti gauge. We then applied this algorithm at linear order and for specific quadratic interactions known as quadratic tail terms. In the present work, we extend this analysis to quadratic interactions associated with the coupling of two mass quadrupole moments, including both instantaneous and hereditary terms. Our main result is the derivation of the metric in Newman-Unti and Bondi gauges with complete quadrupole-quadrupole interactions. We rederive the displacement memory effect and provide expressions for all Bondi aspects and dressed Bondi aspects relevant to the study of leading and subleading memory effects. Then we obtain the Newman-Penrose charges, the BMS charges as well as the second and third order celestial charges defined from the known second order and novel third order dressed Bondi aspects for mass monopole-quadrupole and quadrupole-quadrupole interactions.
Colour evolution and infrared physics
Authors: Plätzer Simon 
Published: July 2023

Abstract
We give a complete account of how soft gluon, massless quark, evolution equations in colour space originate, from a factorization into a hard cross section density operator and a soft function encoding measurements and the projection on definite colours. We detail this formalism up to the two loop level and we demonstrate how the evolution kernels relate to infrared subtractions, and how the resolution of infrared singular regions conspires with the structure of observables the algorithm should be able to predict. The latter allows us to address evolution in different kinematic variables, including energy ordering and angular cutoffs in non-global observables. The soft factor and its evolution resembles a hadronization model including effects such as colour reconnection, and could give insight into the structure of power corrections in observables which require soft gluon evolution.

is a superconformal primary with charge p and degeneracy i. These physical observables, called integrated correlators, are modular-invariant functions of Yang-Mills coupling τ. The Laplace-difference equation is a recursion relation that relates integrated correlators of operators with different charges. In this paper, we introduce the generating functions for these integrated correlators that sum over the charge. By utilising the Laplace-difference equation, we determine the generating functions for all the integrated correlators, in terms of the initial data of the recursion relation. We show that the transseries of the integrated correlators in the large-p (i.e. large-charge) expansion for a fixed N consists of three parts: 1) is independent of τ, which behaves as a power series in 1/p, plus an additional log(p) term when i = j; 2) is a power series in 1/p, with coefficients given by a sum of the non-holomorphic Eisenstein series; 3) is a sum of exponentially decayed modular functions in the large-p limit, which can be viewed as a generalisation of the non-holomorphic Eisenstein series. When i = j, there is an additional modular function of τ that is independent of p and is fully determined in terms of the integrated correlator with p = 2. The Laplace-difference equation was obtained with a reorganisation of the operators that means the large-charge limit is taken in a particular way here. From these SL(2, ℤ)-invariant results, we also determine the generalised ’t Hooft genus expansion and the associated large-p non-perturbative corrections of the integrated correlators by introducing λ = p$$ {g}_{YM}^2 $$

. The generating functions have subtle differences between even and odd N, which have important consequences in the large-charge expansion and resurgence analysis. We also consider the generating functions of the integrated correlators for some fixed p by summing over N, and we study their large-N behaviour, as well as comment on the similarities and differences between the large-p expansion and the large-N expansion.
Near-extremal limits of de Sitter black holes
Authors: Castro Alejandra , Mariani Francesca , Toldo Chiara 
Published: July 2023

Abstract
We analyze the thermodynamic response near extremality of charged black holes in four-dimensional Einstein-Maxwell theory with a positive cosmological constant. The latter exhibit three different extremal limits, dubbed cold, Nariai and ultracold configurations, with near-horizon geometries AdS2 × S2, dS2 × S2, Mink2 × S2, respectively. For each of these three cases we analyze small deformations away from extremality, and contrast their response. We also construct the effective two-dimensional theory, obtained by dimensional reduction, that captures these features and provide a more detailed analysis of the perturbations around the near-horizon geometry for each case. Our results for the ultracold case in particular show an interesting interplay between the entropy variation and charge variation, realizing a different response in comparison to the other two near-extremal limits.
Emerging roles of the cellular prion protein (PrPC) and 37/67 kDa laminin receptor (RPSA) interaction in cancer biology
Authors: Limone Adriana , Maggisano Valentina , Sarnataro Daniela , Bulotta Stefania 
Published: July 2023

AbstractThe cellular prion protein (PrPC) is well-known for its involvement, under its pathogenic protease-resistant form (PrPSc), in a group of neurodegenerative diseases, known as prion diseases. PrPC is expressed in nervous system, as well as in other peripheral organs, and has been found overexpressed in several types of solid tumors. Notwithstanding, studies in recent years have disclosed an emerging role for PrPC in various cancer associated processes. PrPC has high binding affinity for 37/67 kDa laminin receptor (RPSA), a molecule that acts as a key player in tumorigenesis, affecting cell growth, adhesion, migration, invasion and cell death processes. Recently, we have characterized at cellular level, small molecules able to antagonize the direct PrPC binding to RPSA and their intracellular trafficking. These findings are very crucial considering that the main function of RPSA is to modulate key events in the metastasis cascade. Elucidation of the role played by PrPC/RPSA interaction in regulating tumor development, progression and response to treatment, represents a very promising challenge to gain pathogenetic information and discover novel specific biomarkers and/or therapeutic targets to be exploited in clinical settings. This review attempts to convey a detailed description of the complexity surrounding these multifaceted proteins from the perspective of cancer hallmarks, but with a specific focus on the role of their interaction in the control of proliferation, migration and invasion, genome instability and mutation, as well as resistance to cell death controlled by autophagic pathway.

. A popular numerical approach is the so-called Greedy Rank-One Update Algorithm, based on a particular tensor decomposition. The numerical experiments support the fact that this algorithm converges especially fast when the matrix of the linear system is Laplacian-Like. These matrices that follow the tensor structure of the Laplacian operator are formed by sums of Kronecker product of matrices following a particular pattern. Moreover, this set of matrices is not only a linear subspace it is a Lie sub-algebra of a matrix Lie Algebra. In this paper, we characterize and give the main properties of this particular class of matrices. Moreover, the above results allow us to propose an algorithm to explicitly compute the orthogonal projection onto this subspace of a given square matrix $$A \in \mathbb {R}^{N\times N}.$$

AbstractPurposeThis study aimed to review studies comparing transtendon repair (TTR) with tear completion repair (TCR) techniques for partial articular‐sided supraspinatus tendon avulsion (PASTA) lesions according to postoperative patient‐reported outcomes and complications.MethodsDatabases, including PubMed, Embase, Scopus, and Cochrane, were searched for studies published between 2008 and 2022 that directly compared the postoperative patient‐reported outcomes and complications of the TTR and TCR techniques for PASTA lesions. Odds ratios (ORs) were calculated for dichotomous outcomes, while mean differences (MDs) were calculated for continuous outcomes.ResultsA total of seven studies (497 shoulders) were analysed. No statistically significant differences in the postoperative clinical outcomes at the final follow‐up were observed between the TTR and TCR techniques for PASTA lesions. The overall retear rates of the TTR and TCR techniques were 7.7% and 11.6%, respectively (corresponding healing rates were 92.3% and 88.4%), whereas the overall occurrence rates of adhesive capsulitis were 4.7% and 3.3%, respectively. Furthermore, no significant difference was observed in postoperative range of motion (forward flexion, MD = − 1.22, 95% confidence interval (95%CI) − 5.28 to 3.34, n.s.; external rotation, MD = − 1.39, 95% CI − 3.19 to 0.42, n.s.), overall retear rate (OR 0.72, 95% CI 0.29–1.08, n.s.), and occurrence rate of adhesive capsulitis (OR 1.11, 95% CI 0.35–3.52, n.s.) between the two techniques.ConclusionBoth techniques improve clinical outcomes while having a low complication rate and a high rate of healing. No significant difference in clinical outcomes was observed between the two techniques.Level of evidenceIII.
Gender and degree of tendon healing are independent predictive factors for clinical outcome in successfully healed rotator cuff tears
Authors: Şahin Koray , Albayrak Muhammed Oğuzhan , Şentürk Fatih , Ersin Mehmet , Erşen Ali 
Published: July 2023

AbstractPurposeArthroscopic rotator cuff repair (aRCR) is a commonly performed procedure and has been reported to be a successful treatment. Successful healing has traditionally been considered to be associated with good outcome; however, knowledge on predictive factors affecting final outcome other than tendon healing is limited. This study aims to investigate predictive factors influencing clinical outcome following aRCR in patients with successfully healed tears.MethodsThis retrospective case–control study was conducted in a single center with 135 patients who had successfully healed tendons based on Sugaya classification (grades I–III) on postoperative magnetic resonance imaging (MRI) scans following aRCR. Clinical outcome measures included Constant–Murley score (CMS), range of motion (ROM), pain score. Various preoperative, intraoperative factors and degree of postoperative tendon healing were assessed to identify independent predictive factors for final clinical outcome.ResultsMean age of patients was 55.9 ± 9.0 years and mean follow‐up duration was 46.8 ± 14.9 months. There were 50 (37%) male and 85 (63.0%) female patients. At final follow‐up, mean CMS was 85.7 ± 12.0. Considering mean postoperative CMS and the minimal clinically important difference (MCID) of 10 points for CMS, a cutoff level of 75 points for CMS was set (85–10 = 75) and study population was divided into two study groups (group I, poor outcome, CMS ≤ ;75, and group II, good outcome, CMS > 75). There were 24 (17.8%) patients in group I and 111 (82.2%) patients in group II. Univariate analysis revealed that gender, body mass index (BMI) and degree of tendon healing (Sugaya classification) differed significantly between two groups (p < 0.05). Multivariate logistic regression analysis which was conducted with these variables showed that female gender (odds ratio 3.65) and Sugaya grade III (odds ratio 8.19) were independent predictive factors which were significantly associated with poor outcome (p < 0.05).ConclusionsThis study showed that despite achieving a successful healing, considerable amount of patients (17.8%) have ended up with poor outcome. Female gender and degree of tendon healing were identified as independent predictive factors for poor outcome. These data would help surgeons during decision‐making, risk assessment and patient counseling.Level of evidenceIII.

AbstractPurposeTo describe injury incidence, time trends in injury incidence, and injury characteristics among Swedish Olympic athletes over 22 years based on insurance data, as a first step to inform injury preventive measures among Olympic athletes.MethodsThe cohort comprised 762 elite athletes (54% males; age 26.5 ± 5.9 years) in 38 sports in the Swedish Olympic Committee support program ‘Top and Talent’ between 1999 and 2020, with total 3427 athlete‐years included. Acute and gradual onset injuries were reported to the insurance registry by the athletes’ medical staff.ResultsA total of 1635 injuries in 468 athletes were registered. The overall injury incidence was 47.7 injuries/100 athlete‐years (one injury per athlete every second year). An increasing trend in injury incidence was observed in the first decade 2001 to 2010 (annual change 6.0%, 95% CI 3.3–8.8%), while in the second decade 2011 to 2020 no change was evident (0.4%, 95% CI − 1.9 to 2.7%). Gymnastics, tennis, and athletics had the highest incidence (100.0, 99.3, and 93.4 injuries/100 athlete‐years, respectively). Among sport categories, mixed and power sports had the highest incidence (72.8 and 69.5 injuries/100 athlete‐years, respectively). Higher incidences were seen in the younger age groups (≤ 25 years) in mixed and skill sports. The injury incidence was comparable between male and female athletes, and summer and winter sports. Most injuries occurred in the lower limb, and specifically the knee (24%), foot/ankle (15%) and spine/pelvis (13%).ConclusionThe results on injury patterns in different sports and age groups may guide preventive focus for health and performance teams working with Olympic athletes.Level of evidenceII.

Published: July 2023

AbstractAdditive manufacturing (AM) processes present unique opportunities for the repair of high-value-added industrial and consumer plastic products, which otherwise are destined for the landfill at the end of their life and contribute to the growing environmental and health issues. In this work, we propose a novel method of integrating fused filament-based additive fabrication with the hot staking method to repair a complex automotive component, namely headlight. Newly formulated polypropylene-based composite filaments were used to 3D print a set of staking posts and the missing brackets in the damaged headlight to enable their effective reuse of the repaired assembly. Three staking designs were tested in the first phase of the experiments with the respective geometrical configurations, viz. knurled, domed, and hollow. Strength tests were conducted to rank the performance of the joints against the highest ultimate shear strength values, toughness, and repeatability. The joint design with a domed-shaped profile ranked the best across these criteria. In the second phase of the study, the main printing parameters, including printing temperature, nozzle head penetration in the substrate, printing speed, and layer height, were optimised to increase the joint strength. Based on the design of experiment, the dome-shaped stakes, which were printed using a nozzle temperature of 240 $$^\circ{\rm C}$$

Estimating the effects of Syrian civil war
Authors: Kešeljević Aleksandar , Spruk Rok 
Published: July 2023

AbstractWe estimate the effects of the Syrian civil war using a synthetic control method which is based on a counterfactual scenario of an absence of the armed conflict that has led to the humanitarian crisis and one of the largest population displacements without a precedent in modern history. By comparing Syria’s growth and development trajectories with the characteristics of a set of sixty-six countries with no armed internal conflict between 1996 and 2021, we can deduce a series of gaps in economic growth, human development, and institutional quality that can be attributed to the civil war. Our analysis shows that the effect of the Syrian civil war on the trajectory of economic growth was temporary and almost disappeared before the start of the COVID-19 pandemic. Conversely, the war led to an unprecedented decline in human development, a high rise in infant mortality, and a prevalent degradation of institutional quality. To the present day, the civil war has led to more than 4500 additional infant deaths with a permanently derailed trajectory of longevity. The unparalleled and permanent deterioration in institutional quality resulting from the war is indicated by a diminished rule of law, civil liberties, government efficiency, and a widespread escalation of corruption. To ensure the internal validity of the findings, the estimated effects were subjected to and passed a variety of placebo checks.

Are medication effects on subjective response to alcohol and cue-induced craving associated? A meta regression study
Authors: Ray Lara A. , Nieto Steven J. , Meredith Lindsay R. , Burnette Elizabeth , Donato Suzanna , Magill Molly , Du Han 
Published: July 2023

Abstract
Rationale
Alcohol administration and cue-reactivity paradigms are frequently used to screen for the initial efficacy of medications for alcohol use disorder (AUD). While medication effects on the primary outcomes for these paradigms are assumed to be qualitatively related, there is a critical lack of quantitative evidence to support this hypothesis.

Objectives
The study aims to test the relationship between medication effect sizes on subjective response to alcohol administration and medication effect sizes for cue-induced craving to cue exposure, using meta-analysis.

Methods
Systematic literature searches were conducted to identify randomized trials, wherein AUD medications were tested using the alcohol administration and/or cue-reactivity paradigms. From these studies, descriptive statistics were collected to compute medication effect sizes on the primary outcomes for each respective paradigm. With medication as the unit of analysis, medication effect sizes in alcohol administration studies were compared with medication effect sizes in cue-reactivity studies using the Williamson-York regression which allows for meta-regression across independent samples.

Results
Medication effect sizes on alcohol-induced stimulation and alcohol-induced craving were not significantly associated with medication effect sizes on cue-induced alcohol craving (k stimulation = 10 medications, $$\widehat{\beta }=0.272 \left(\mathrm{SE}=0.263\right), p=0.150$$

Conclusions
With the exception of alcohol-induced sedation, there is little quantitative evidence of medication effects on subjective response domains measured during alcohol administration parallel medication effects on cue-induced alcohol craving. To provide additional context to the current study, future work should examine whether cue-reactivity findings predict clinical trial outcomes.
