Strong coupling expansions in $$ \mathcal{N} $$ = 2 quiver gauge theories
Authors: Billò M. , Frau M. , Lerda A. , Pini A. , Vallarino P. 
Published: January 2023

Abstract
We study the 3-point functions of gauge-invariant scalar operators in four dimensional $$ \mathcal{N} $$
N
= 2 superconformal quiver theories using supersymmetric localization in the planar limit of a large number of colors. By exploiting a web of nontrivial relations, we show that the 3-point functions can be expressed in terms of the 2-point functions through exact Ward-like identities that are valid for all values of the coupling constant. In this way, using recent results about the 2-point functions, we are able to obtain the asymptotic strong-coupling expansion of the 3-point functions and of the corresponding structure constants in the planar limit. Our results extend to sub-leading orders what has been recently found at leading order, where a precise match with calculations within the AdS/CFT correspondence at the supergravity level is possible. Therefore, our findings can be interpreted also as a prediction for the sub-leading string corrections to these holographic calculations.
Cobordism, singularities and the Ricci flow conjecture
Authors: Velázquez David Martín , De Biasio Davide , Lüst Dieter 
Published: January 2023

Abstract
In the following work, an attempt to conciliate the Ricci flow conjecture and the Cobordism conjecture, stated as refinements of the Swampland distance conjecture and of the No global symmetries conjecture respectively, is presented. This is done by starting from a suitable manifold with trivial cobordism class, applying surgery techniques to Ricci flow singularities and trivialising the cobordism class of one of the resulting connected components via the introduction of appropriate defects. The specific example of $$ {\varOmega}_4^{SO} $$

SO

is studied in detail. A connection between the process of blowing up a point of a manifold and that of taking the connected sum of such with ℂℙn is explored. Hence, the problem of studying the Ricci flow of a K3 whose cobordism class is trivialised by the addition of 16 copies of ℂℙ2 is tackled by applying both the techniques developed in the previous sections and the classification of singularities in terms of ADE groups.

Published: January 2023

Abstract
Aim
To assess radiological and functional outcomes of transilial internal fixator (TIFI) for treatment of sacral complete transforaminal fractures with a novel implantation technique that decrease wound irritation problems in addition to facilitating easy application of reduction methods beside showing the best entry points, screw trajectories and angles.

Methods
A Prospective case series from 2019 to 2021 was conducted at university hospital including 72 patients with Denis type 2 sacral fractures. The operative and fluoroscopy time, reduction, implantation techniques, postoperative radiological and functional data were collected and evaluated with minimum follow-up of 12 months.

Results
The mean initial fracture displacement was 4.42 mm while mean postoperative maximum residual fracture displacement was 2.8 mm, Radiological outcome assessed using Matta’s grading at the final follow-up visit with 63 cases scored as Excellent,7 cases as Good, 2 cases as fair. Functional outcome using Majeed scoring shows 64 cases of Excellent grading and 8 cases were Good. Short operative and fluoroscopy time, easy reduction techniques, few skin problems were recorded.

Conclusion
TIFI through a minimally invasive technique represents a valid method for dealing with transforaminal sacral fractures. TIFI provides a rigid fixation for posterior ring injuries with few risks regarding iatrogenic nerve injury, avoiding different variations of upper sacral osseous anatomy or sacral dysmorphism. In addition, there is no necessity for high quality fluoroscopy for visualization of sacral foramina intraoperatively, decreasing risk of radiation exposure, unlike other methods of fixation as iliosacral screws. Our novel modification for implantation technique provides few risks for postoperative and wound complications.

AbstractWe study the microbiome of sea water collected from two locations of the Barbadian coral reefs. The two sites differ in several environmental and ecological variables including their endogenous benthic community and their proximity to urban development and runoffs from inland watersheds. The composition of the microbial communities was estimated using whole genome DNA shotgun sequencing with adjuvant measurements of chemical and environmental qualities. Although both sites exhibit a similar degree of richness, the less urbanized site (Maycocks reef at Hangman’s Bay) has a strong concentration of phototrophs whereas the more urbanized location (Bellairs reef at Folkstone) is enriched for copiotrophs, macroalgal symbionts and marine-related disease-bearing organisms from taxa scattered across the tree of life. Our results are concordant with previous profiles of warm ocean surface waters, suggesting our approach captures the state of each coral reef site, setting the stage for longitudinal studies of marine microbiome dynamics in Barbados.

AbstractCoral reefs in the northern Red Sea experience strong seasonality. This affects reef carbon (C) cycling, but ecosystem-wide quantification of C fluxes in such reefs is limited. This study quantified seasonal reef community C fluxes with incubations. Resulting data were then incorporated into seasonal linear inverse models (LIM). For spring, additional sponge incubation results allowed for unique assessment of the contribution of sponges to C cycling. The coral reef ecosystem was heterotrophic throughout all seasons as gross community primary production (GPP; 136–200, range of seasonal means in mmol C m−2 d−1) was less than community respiration (R; 192–279), and balanced by import of organic carbon (52–100), 88‒92% of which being dissolved organic carbon (DOC). Hard coral GPP (74–110) and R (100–137), as well as pelagic bacteria DOC uptake (58–101) and R (42–86), were the largest C fluxes across seasons. The ecosystem was least heterotrophic in spring (highest irradiance) (GPP:R 0.81), but most heterotrophic in summer and fall with higher water temperatures (0.68 and 0.60, respectively). Adding the sponge community to the model increased community R (247 ± 8 without to 353 ± 13 with sponges (mean ± SD)). Sponges balanced this demand primarily with DOC uptake (105 ± 6, 97% by cryptic sponges). This rate is comparable to the uptake of DOC by pelagic bacteria (104 ± 5) placing the cryptic sponges among the dominant C cycling groups in the reef.
Comparison of water and cryogenic fluid hammer experiments for rocket engine feed line systems
Authors: Klein Sebastian , Traudt Tobias , Oschwald Michael 
Published: January 2023

Abstract
Fluid hammer occurs when a flow in a pipeline is rapidly stopped due to valve closure or shutting down a pump. The resulting pressure wave can reach very high amplitudes, depending on the fluid properties and the flow velocity. In spacecrafts and launchers, where the reduction of weight is always an important design goal, it is not possible to build the structure arbitrarily robust. Understanding the transient behaviour of the fluids is necessary to predict mechanical loads on the structure and align the design to them. Since a lot of launchers use reactive, cryogenic propellants, it is a common approach to use inert substitute fluids for on ground testing like water (H2O) or liquid nitrogen (LN2). LN2 comes with the advantage of being cryogenic like real propellants, but ground testing is consequently more complex than with H2O. For this purpose, several fluid hammer experiments with both fluids were performed and compared to each other to provide a foundation for deciding which substitute fluid would be useful.

Abstract
Background
One-Anastomosis Gastric Bypass (OAGB) is the third most common bariatric operation for patients with obesity worldwide. One concern about OAGB is the presence of acid and non-acid reflux in a mid- and long-term follow-up. The aim of this study was to objectively evaluate reflux and esophagus motility by comparing preoperative and postoperative mid-term outcomes.

Setting
Cross-sectional study; University-hospital based.

Methods
This study includes primary OAGB patients (preoperative gastroscopy, high-resolution manometry (HRM), and impedance-24 h-pH-metry) operated at Medical University of Vienna before 31st December 2017. After a mean follow-up of 5.1 ± 2.3 years, these examinations were repeated. In addition, history of weight, remission of associated medical problems (AMP), and quality of life (QOL) were evaluated.

Results
A total of 21 patients were included in this study and went through all examinations. Preoperative weight was 124.4 ± 17.3 kg with a BMI of 44.7 ± 5.6 kg/m2, total weight loss after 5.1 ± 2.3 years was 34.4 ± 8.3%. In addition, remission of AMP and QOL outcomes were very satisfactory in this study. In gastroscopy, anastomositis, esophagitis, Barrett´s esophagus, and bile in the pouch were found in: 38.1%, 28.3%, 9.5%, and 42.9%. Results of HRM of the lower esophageal sphincter pressure were 28.0 ± 15.6 mmHg, which are unchanged compared to preoperative values. Nevertheless, in the impedance-24 h-pH-metry, acid exposure time and DeMeester score decreased significantly to 1.2 ± 1.2% (p = 0.004) and 7.5 ± 8.9 (p = 0.017). Further, the total number of refluxes were equal to preoperative; however, the decreased acid refluxes were replaced by non-acid refluxes.

Conclusion
This study has shown decreased rates of acid reflux and increased non-acid reflux after a mid-term outcome of primary OAGB patients. Gastroscopy showed signs of chronic irritation of the gastrojejunostomy, pouch, and distal esophagus, even in asymptomatic patients. Follow-up gastroscopies in OAGB patients after 5 years may be considered.

Statistical guarantees for sparse deep learning
Authors: Lederer Johannes 
Published: January 2023

AbstractNeural networks are becoming increasingly popular in applications, but our mathematical understanding of their potential and limitations is still limited. In this paper, we further this understanding by developing statistical guarantees for sparse deep learning. In contrast to previous work, we consider different types of sparsity, such as few active connections, few active nodes, and other norm-based types of sparsity. Moreover, our theories cover important aspects that previous theories have neglected, such as multiple outputs, regularization, and $$\ell_{2}$$

-loss. The guarantees have a mild dependence on network widths and depths, which means that they support the application of sparse but wide and deep networks from a statistical perspective. Some of the concepts and tools that we use in our derivations are uncommon in deep learning and, hence, might be of additional interest.
Social inclusion and the use of sign language inset during the 2019 Philippine SONA
Authors: Espineda Melvin N. 
Published: January 2023

AbstractThis phenomenological study, guided by Radcliffe-(1881–1955) Brown's Structural Functionalism Theory, investigated how sign language inset was used for social inclusion during the 2019 Philippine State of the Nation Address on GMA Network, Inc. Eight participants' lived experiences were examined through in-depth interviews. Four major themes emerged: exposure and familiarization with the deaf community culture, which is the Filipino Sign Language (FSL); adjustment of the TV inset size for deaf visual signs recognition and understanding; validation of TV insets interpreting with a deaf consultant; accessibility to communication through clear policy and guidelines of TV inset interpreting. The study concludes that even though the sign language interpreters use FSL, we can only elicit social inclusion by adjusting the size of the TV inset; since the sign language insets require the visual signs of the SLIs, which include hand gestures and facial expressions. Moreover, a better understanding of the signs that consider both schooled and non-schooled Deaf requires the exposure and familiarization of SLIs with the deaf culture. Meanwhile, TV networks should consider adjusting the size of the TV inset, hiring a deaf consultant to validate signing, and ensuring deaf access to communication to integrate them socially. Sign language inset implementation requires a model to follow structurally to be functional.
Genetische Diagnostik bei ungewollt kinderlosen Paaren oder wiederholten Fehlgeburten
Authors: Rudnik-Schöneborn Sabine , Wyrwoll Margot J. , Tüttelmann Frank , Toth Bettina , Pinggera Germar-M. , Zschocke Johannes 
Published: January 2023

ZusammenfassungEtwa 10–15 % aller Paare sind ungewollt kinderlos, entweder durch das fehlende Eintreten einer Schwangerschaft oder durch rezidivierende Aborte. Nachweisbare Ursachen einer Fertilitätsstörung finden sich gleichermaßen bei Männern und bei Frauen, bei einem Drittel sind beide Partner beteiligt. Bei 5–10 % der weiblichen und 10–20 % der männlichen Patienten sind mit den derzeit etablierten diagnostischen Analysen genetische Ursachen erkennbar. Eine ätiologische Abklärung erlaubt eine fundierte Prognose und manchmal eine spezifische Therapie, sie kann auf ein erhöhtes Risiko des Auftretens kindlicher Erkrankungen hinweisen. Eine spezifische genetische Abklärung ist daher unabhängig von einer gegebenenfalls geplanten reproduktionsmedizinischen Behandlung bei allen Paaren indiziert, die länger als ein Jahr vergeblich versuchen, ein Kind zu bekommen, und bei denen keine andere Erklärung für eine Unfruchtbarkeit nachgewiesen wurde. Die genetische Diagnostik der Unfruchtbarkeit umfasst bei beiden Partnern in der Regel eine klassische Karyotypisierung zum Nachweis einer gegebenenfalls vorliegenden gonosomalen oder balancierten strukturellen Chromosomenveränderung. Dies ist insbesondere beim wiederholten Auftreten von Fehlgeburten bei beiden Partnern indiziert. Abhängig von hormonellen Befunden sollte bei Frauen ein attenuiertes adrenogenitales Syndrom bzw. bei Verdacht auf eine primäre Ovarialinsuffizienz eine FMR1-Prämutation ausgeschlossen werden. Die genetische Diagnostik des Mannes bei Azoospermie oder gegebenenfalls bei schwerer Oligozoospermie umfasst zusätzlich zur Karyotypisierung die Testung auf AZF-Mikrodeletionen (AZF Azoospermiefaktor) sowie in Abhängigkeit von den klinischen Parametern auf pathogene Varianten im CFTR-Gen als mögliche Ursache einer obstruktiven Azoospermie. Sequenzanalysen spezifischer Gene können bei Frauen und Männern mit hypogonadotropem Hypogonadismus oder bei Verdacht auf eine monogene Spermatogenesestörung in Betracht gezogen werden. Gemäß den Leitlinien und nationalen gesetzlichen Grundlagen sollten vor der genetischen Diagnostik sowie beim Nachweis genetischer Ursachen einer Infertilität mögliche Konsequenzen und die Bedeutung für zukünftige Kinder im Rahmen einer genetischen Beratung besprochen werden.
Privacy in electronic health records: a systematic mapping study
Authors: Tertulino Rodrigo , Antunes Nuno , Morais Higor 
Published: January 2023

Abstract
Main
Electronic health record (EHR) applications are digital versions of paper-based patient health information. Traditionally, medical records are made on paper. However, nowadays, advances in information and communication technology have made it possible to change medical records from paper to EHR. Therefore, preserving user data privacy is extremely important in healthcare environments. The main challenges are providing ways to make EHR systems increasingly capable of ensuring data privacy and at the same time not compromising the performance and interoperability of these systems.

Subject and methods
This systematic mapping study intends to investigate the current research on security and privacy requirements in EHR systems and identify potential research gaps in the literature. The main challenges are providing ways to make EHR systems increasingly capable of ensuring data privacy, and at the same time, not compromising the performance and interoperability of these systems. Our research was carried out in the Scopus database, the largest database of abstracts and citations in the literature with peer review.

Results
We have collected 848 articles related to the area. After disambiguation and filtering, we selected 30 articles for analysis. The result of such an analysis provides a comprehensive view of current research.

Conclusions
We can highlight some relevant research possibilities. First, we noticed a growing interest in privacy in EHR research in the last 6 years. Second, blockchain has been used in many EHR systems as a solution to achieve data privacy. However, it is a challenge to maintain traceability by recording metadata that can be mapped to private data of the users applying a particular mapping function that can be hosted outside the blockchain. Finally, the lack of a systematic approach between EHR solutions and existing laws or policies leads to better strategies for developing a certification process for EHR systems.

AbstractCash transfers are increasingly used to motivate adherence to HIV care. However, evidence on cash transfers and intimate partner violence (IPV) is mixed and little is known about their safety for women living with HIV. We conducted in-depth interviews with women living with HIV who participated in a randomized trial providing 6 months of cash transfers (~$4.5 or $11 USD) conditional on HIV clinic attendance in Shinyanga, Tanzania to assess how receiving cash affects IPV and relationship dynamics. Eligible participants were 18–49 years, received cash transfers, and in a partnership at baseline. Data were analyzed in Dedoose using a combined inductive-deductive coding approach. 25 interviews were conducted between November 2019-February 2020. Women’s employment was found to be a source of household tension and violence. None of the participants reported physical or sexual IPV in relation to cash transfers, however, some women experienced controlling behaviors or emotional violence including accusations and withholding of money, particularly those who were unemployed. Cash transfers were predominantly used for small household expenses and were not viewed as being substantial enough to shift the financial dynamic or balance of power within relationships. Our findings suggest that small, short-term cash transfers do not increase physical or sexual IPV for women living with HIV however can exacerbate controlling behaviors or emotional violence. Modest incentives used as a behavioral nudge to improve health outcomes may affect women differently than employment or larger cash transfers. Nonetheless, consultations with beneficiaries should be prioritized to protect women from potential IPV risks.

Published: January 2023

AbstractAdolescents with disability in the Global South have unique sexual and reproductive health (SHR) experiences and needs; however, they are rarely included in SRH discourse. This qualitative study, conducted in rural Bangladesh, used semi-structured interviews to understand how adolescents with cerebral palsy (CP) experience their SRH. Participants were recruited from the Bangladesh Cerebral Palsy Register and included 24 adolescents with CP (n = 12 female; n = 12 male) and 76 parents (n = 56 mothers, n = 17 fathers, n = 3 other relatives). Data were analyzed using reflexive thematic analysis. Findings highlighted heterogeneity among adolescents with CP including differences for adolescent men versus women. For some adolescent men with CP, sexual maturity was viewed as bringing new opportunities, whereas for other men, adolescence affirmed exclusions and some transgressed sociocultural norms as they struggled to navigate their pubescent body alongside new privacy requirements. For adolescent women with CP, sexual maturity was associated with new domestic responsibilities, silence and secrecy regarding menstruation, and increased vulnerability to sexual violence and abuse. Adolescent men and women with CP spoke about marriage as something “everybody wants,” however, was deemed “impossible” for those with more impairment-related support needs. Both adolescent men and women with CP lacked access to SRH information and support. Mothers positioned providing care to their adolescent child with CP after puberty as “shameful.” Our findings suggest that disability, health, and education services in rural Bangladesh need to adopt a life-course approach that incorporates the SRH of adolescents with CP. We recommend the provision of SRH education that addresses the physical, cognitive, and social needs of adolescents with CP.
Molecular characterization of eliminated chromosomes in Hessian fly (Mayetiola destructor (Say))
Authors: Crane Yan M. , Crane Charles F. , Cambron Sue E. , Springmeyer Lucy J. , Schemerhorn Brandon J. 
Published: January 2023

AbstractLike other cecidomyiid Diptera, Hessian fly has stable S chromosomes and dispensable E chromosomes that are retained only in the germ line. Amplified fragment length polymorphisms (AFLP), suppressive subtractive hybridization (SSH), fluorescent in-situ hybridization (FISH), and sequencing were used to investigate similarities and differences between S and E chromosomes. More than 99.9% of AFLP bands were identical between separated ovary and somatic tissue, but one band was unique to ovary and resembled Worf, a non-LTR retrotransposon. Arrayed clones, derived by SSH of somatic from ovarian DNA, showed no clones that were unique to ovary. FISH with BAC clones revealed a diagnostic banding pattern of BAC positions on both autosomes and both sex chromosomes, and each E chromosome shared a pattern with one of the S chromosomes. Sequencing analysis showed that E chromosomes are nearly identical to S chromosomes, since no sequence could be confirmed to belong only to E chromosomes. There were a few questionably E-specific sequences that are candidates for further investigation. Thus, the E chromosomes appear to be derived from S chromosomes by the acquisition or conversion of sequences that produce the negatively heteropycnotic region around the centromere.
