Interacting emergent Yang-Mills theory

Published: May 2022

Abstract
In this article, subleading (in 1/N) corrections to the action of the one loop dilatation operator in the su(3) sector of $$ \mathcal{N} $$
N
= 4 super Yang-Mills theory are studied. We focus on the system of operators dual to two giant graviton systems, which have a bare dimension ∼ $$ \mathcal{O} $$
O
(N) and are a linear combination of restricted Schur polynomials with p = 2 long columns. At the leading order the dilatation operator gives rise to the free part of an emergent Yang-Mills theory, arising from the open string excitations of the giant gravitons. We verify that the terms we study describe interactions between these open string excitations. The interactions have the U(1)×U(1) gauge invariance expected for a pair of separated branes.
Integrable deformations of AdS/CFT

Published: May 2022

Abstract
In this paper we study in detail the deformations introduced in [1] of the integrable structures of the AdS2,3 integrable models. We do this by embedding the corresponding scattering matrices into the most general solutions of the Yang-Baxter equation. We show that there are several non-trivial embeddings and corresponding deformations. We work out crossing symmetry for these models and study their symmetry algebras and representations. In particular, we identify a new elliptic deformation of the AdS3× S3× M4 string sigma model.
Global and local performances of a tubular micro-pulsating heat pipe: experimental investigation

AbstractHeat exchanger optimization is mandatory in almost any industrial application. Thanks to their performances, the Pulsating Heat Pipes (PHPs) are a very interesting application. Micro-PHPs, which are defined as PHPs with a tube that has a hydraulic diameter < 500 μm, have shown big advantages in terms of their ability to dissipate high heat fluxes, their reduced size, and their low weight. However, the great majority of the works that investigate the thermal behavior of micro-PHPs only deal with the average performance of the system, usually represented in terms of global thermal resistance of the device. Our study aims to begin to fill this lack by investigating the local thermal behavior of a typical multi-turn micro-PHP. A micro-PHP characterized by seven turns and realized with a stainless-steel pipe was investigated. It was positioned in a vertical position, with the evaporator at the bottom, and it was partially loaded with HFC-134a. The studied micro-PHP is tubular, while almost the totality of the micro-PHPs investigated to date are constituted by microchannels engraved in silicon-based wafer, and they present a great potential in terms of three-axis flexibility compared to the flat micro-PHPs that are usually investigated. To highlight the different thermal functioning of each turn, an infrared camera was used to acquire the local temperature distributions on the wall of the PHP condenser. It was found that the best performance was reached for a filling ratio of 46% and for a heat input ranging between 1.9–3.7 W. To thoroughly study the pulsating behavior of the proposed PHP, the dominant frequencies were investigated by performing a wavelet analysis. The results allow the identification of different flow regimes, such as start-up, non-persistent oscillating flow (0.05–0.6 Hz; Qnet < 2.3 W), and quasi-periodic oscillating flow (0.6–1.5 Hz; Qnet = 2.8–4.7 W). Eventually, the results highlight that the approach proposed herein can provide worthy evidence about the fluid motion inside the PHP, thereby allowing to overcome the limits introduced by the adoption of transparent materials for the direct flow visualization or by the invasive insertion of pressure sensors, particularly in devices with such small dimensions.

Abstract
Purpose
To systematically review the published literature on surgical margins as a risk factor for local recurrence (LR) in patients undergoing partial nephrectomy (PN) for pT1 renal cell carcinomas (RCC).

Evidence acquisition
A systematic literature search of relevant databases (MEDLINE, Embase and the Cochrane Library) was performed according to the PRISMA criteria up to February 2022. The hypothesis was developed using the PPO method (Patients = patients with pT1 RCC undergoing PN, Prognostic factor = positive surgical margins (PSM) detected on final pathology versus negative surgical margins (NSM) and Outcome = LR diagnosed on follow-up imaging). The primary outcome was the rate of PSM and LR. The risk of bias was assessed by the QUIPS tool.

Evidence synthesis
After assessing 1525 abstracts and 409 full-text articles, eight studies met the inclusion criteria. The percentage of PSM ranged between 0 and 34.3%. In these patients with PSM, LR varied between 0 and 9.1%, whereas only 0–1.5% of LR were found in the NSM-group. The calculated odds ratio (95% confident intervals) varied between 0.04 [0.00–0.79] and 0.27 [0.01–4.76] and was statistically significant in two studies (0.14 [0.02–0.80] and 0.04 [0.00–0.79]). The quality analysis of the included studies resulted in an overall intermediate to high risk of bias and the level of evidence was overall very low. A meta-analysis was considered unsuitable due to the high heterogeneity between the included studies.

Conclusion
PSM after PN in patients with pT1 RCC is associated with a higher risk of LR. However, the evidence has significant limitations and caution should be taken with the interpretation of this data.

AbstractThe left axillary artery is an attractive alternative access route for transcatheter aortic valve replacement (TAVR) and may provide better outcomes compared to other alternatives. Nevertheless, there remain concerns about vascular complications, lack of compressibility, and thorax-related complications. Between March 2019 and March 2021, 13 patients underwent transaxillary TAVR for severe aortic stenosis at the University Hospital Bonn. The puncture was performed with a puncture at the distal segment of the axillary artery through the axilla, with additional femoral access for applying a safety wire inside the axillary artery. Device success was defined according to the VARC 2 criteria. The study participants were advanced in age (77 ± 9 years old), and 54% were female, with an intermediate risk for surgery (STS risk score 4.7 ± 2.0%). The average diameter of the distal segment of the axillary artery was 5.8 ± 1.0 mm (i.e., the puncture site) and 7.6 ± 0.9 mm for the proximal axillary artery. Device success was achieved in all patients. 30-day major adverse cardiac and cerebrovascular events were 0%. With complete percutaneous management, stent-graft implantation was performed at the puncture site in 38.5% of patients. Minor bleeding was successfully managed with manual compression. Moreover, no thorax-related complications, hematomas, or nerve injuries were observed. Percutaneous trans-axilla TAVR was found to be feasible and safe. This modified approach may mitigate the risk of bleeding and serious complications in the thorax and be less invasive than surgical alternatives.

Abstract
Background
The understanding of fatal familial insomnia (FFI), a rare neurodegenerative autosomal dominant prion disease, has improved in recent years as more cases were reported. This work aimed to propose new diagnostic criteria for FFI with optimal sensitivity, specificity, and likelihood ratio.

Methods
An international group of experts was established and 128 genetically confirmed FFI cases and 281 non-FFI prion disease controls are enrolled in the validation process. The new criteria were proposed based on the following steps with two-round expert consultation: (1) Validation of the 2018 FFI criteria. (2) Diagnostic item selection according to statistical analysis and expert consensus. (3) Validation of the new criteria.

Results
The 2018 criteria for possible FFI had a sensitivity of 90.6%, a specificity of 83.3%, with a positive likelihood ratio (PLR) of 5.43, and a negative likelihood ratio (NLR) of 0.11; and the probable FFI criteria had a sensitivity of 83.6%, specificity of 92.9%, with a PLR of 11.77, and a NLR of 0.18. The new criteria included more specific and/or common clinical features, two exclusion items, and summarized a precise and flexible diagnostic hierarchy. The new criteria for possible FFI had therefore reached a better sensitivity and specificity (92.2% and 96.1%, respectively), a PLR of 23.64 and a NLR of 0.08, whereas the probable FFI criteria showed a sensitivity of 90.6%, a specificity of 98.2%, with a PLR of 50.33 and a NLR of 0.095.

Conclusions
We propose new clinical diagnostic criteria for FFI, for a better refining of the clinical hallmarks of the disease that ultimately would help an early recognition of FFI and a better differentiation from other prion diseases.

. As a corollary, we deduce that the negative moments of imaginary chaos on the unit circle do not correspond to the analytic continuation of the Fyodorov-Bouchaud formula, even when well-defined. Somewhat surprisingly, basic density results are not easy to prove for imaginary chaos and one of the main contributions of the article is introducing Malliavin calculus to the study of (complex) multiplicative chaos. To apply Malliavin calculus to imaginary chaos, we develop a new decomposition theorem for non-degenerate log-correlated fields via a small detour to operator theory, and obtain small ball probabilities for Sobolev norms of imaginary chaos.
Manifold turnpikes, trims, and symmetries
Authors: Faulwasser Timm , Flaßkamp Kathrin , Ober-Blöbaum Sina , Schaller Manuel , Worthmann Karl 
Published: May 2022

AbstractClassical turnpikes correspond to optimal steady states which are attractors of infinite-horizon optimal control problems. In this paper, motivated by mechanical systems with symmetries, we generalize this concept to manifold turnpikes. Specifically, the necessary optimality conditions projected onto a symmetry-induced manifold coincide with those of a reduced-order problem defined on the manifold under certain conditions. We also propose sufficient conditions for the existence of manifold turnpikes based on a tailored notion of dissipativity with respect to manifolds. Furthermore, we show how the classical Legendre transformation between Euler–Lagrange and Hamilton formalisms can be extended to the adjoint variables. Finally, we draw upon the Kepler problem to illustrate our findings.

Published: May 2022

AbstractMelanoma is the deadliest form of skin cancer. Early diagnosis of malignant lesions is crucial for reducing mortality. The use of deep learning techniques on dermoscopic images can help in keeping track of the change over time in the appearance of the lesion, which is an important factor for detecting malignant lesions. In this paper, we present a deep learning architecture called Attention Squeeze U-Net for skin lesion area segmentation specifically designed for embedded devices. The main goal is to increase the patient empowerment through the adoption of deep learning algorithms that can run locally on smartphones or low cost embedded devices. This can be the basis to (1) create a history of the lesion, (2) reduce patient visits to the hospital, and (3) protect the privacy of the users. Quantitative results on publicly available data demonstrate that it is possible to achieve good segmentation results even with a compact model.
What lessons can be learned from cost efficiency? The case of Swedish district courts
Authors: Månsson Jonas , Andersson Christian , Bonander Fredrik 
Published: May 2022

AbstractMany studies have reported findings regarding technical efficiency (i.e., resource use) for district courts around the world. However, our review of previous research did not find any studies targeting cost efficiency. To fill this gap, this study investigates the cost efficiency of Swedish district courts. We apply the Farrell framework and decompose cost efficiency into allocative and technical efficiency. The study finds substantial cost inefficiency for district courts in Sweden, which is mainly due to allocative inefficiency (i.e., having the wrong input mix or paying too much for inputs). This result is not surprising since, for example, there is regional heterogeneity in input prices (i.e., wages and rents). However, it also reveals the potential of, for example, moving district courts out of city centres and high-priced areas. On the other hand, the location and staffing of district courts serve other competing policy concerns, such as the proximity of citizens to district courts. The cost-efficiency analysis gives information about the cost of these competing policy concerns.

Print referencing during e-storybook reading on a SMART board for kindergartners to promote early literacy skills
Authors: van Dijken M. J. 
Published: May 2022

AbstractThis study examined the effects of a classroom-focused intervention on different domains of early literacy. The intervention consisted of shared e-book reading combined with a print referencing technique done via a SMART board. The specific goal of the study was to examine whether children could be instructed simultaneously in print knowledge, phonological awareness, and vocabulary, without a loss of impact on the development of either skill. Results revealed significantly larger gains with high effect sizes in print knowledge (ηp2 = .474) and phonological awareness (ηp2 = .370) when children received the print referencing e-book intervention compared to the control conditions. Print referencing did not hinder children’s learning of new words, but enhanced vocabulary to the same extent, or even higher, as e-books typically do in kindergarten when print referencing is not involved. The findings indicate that e-book reading merged with print referencing is a beneficial method for enhancing essential early literacy skills simultaneously. The learning tool is particularly efficient for a tailor-made educational setting, as it allows differential attention to students and lessens the workload for teachers.
One-Step Genotyping Method in loxP-Based Conditional Knockout Mice Generated by CRISPR-Cas9 Technology

Published: May 2022

AbstractWith the development of CRISPR-Cas9 gene editing and in vitro fertilization (IVF) technology, we can now easily construct genetically modified mouse strains with indels, especially for loxP-based strategy. However, the general genotyping methods are time-consuming and unreliable given the loxP site is only 34 bp long. Here, based on the tetra primer-paired PCR amplification, we describe an efficient genotyping method which can simultaneously generate the internal control band, wild type (wt)-genotype band, and/or loxP-genotype band through one single PCR amplification. It is easy to interpret the mouse genotypes from the pattern of the bands. Further, the results could also help to exclude the possibility of minor cross-contamination, since the ratio between the bands’ quantity in wt/wt, wt/loxP, and loxP/loxP mice are relatively constant, which makes the genotyping more reliable when it is performed in a large amount.
Defining left bundle branch block according to the new 2021 European Society of Cardiology criteria
Authors: Calle S. , Timmermans F. , De Pooter J. 
Published: May 2022

AbstractCorrectly diagnosing left bundle branch block (LBBB) is fundamental, as LBBB occurs frequently in heart failure and may trigger a vicious cycle of progressive left ventricular dysfunction. Moreover, a correct diagnosis of LBBB is pivotal to guide cardiac resynchronisation therapy. Since the LBBB diagnostic criteria were recently updated by the European Society of Cardiology (ESC), we assessed their diagnostic accuracy compared with the previous ESC 2013 definition. We further discuss the complexity of defining LBBB within the context of recent insights into the electromechanical pathophysiology of LBBB.
Rolling horizon optimisation based peer-to-peer energy trading under real-time variations in demand and generation
Authors: Kochupurackal Ajai , Pancholi Karnav Prajeshbhai , Islam S. N. , Anwar Adnan , Oo A. M. T. 
Published: May 2022

AbstractThis paper has developed an approach to optimise energy sell and price bids at the sellers along with optimising energy purchase decisions at the buyers in a peer-to-peer (P2P) energy trading market. The optimum price and energy sell bids are designed to maximise the profit at the sellers, while buyers make energy purchase decisions to minimise their energy deficit. The proposed approach relies on a day-ahead optimisation mechanism that can utilise the daily generation and demand patterns as well as a rolling horizon based real-time update strategy when there are variations in generation or demand forecasts. The aforementioned approach is evaluated for a real-life generation and demand dataset under different scenarios. The numerical results demonstrate that when the forecasting error is not very high, the proposed optimisation approach can allow sellers to obtain some profit in most of the time intervals during the day.
