Solving the many-variables problem in MICE with principal component regression
Authors: Costantini Edoardo , Lang Kyle M. , Sijtsma Klaas , Reeskens Tim 
Published: August 2023

AbstractMultiple Imputation (MI) is one of the most popular approaches to addressing missing values in questionnaires and surveys. MI with multivariate imputation by chained equations (MICE) allows flexible imputation of many types of data. In MICE, for each variable under imputation, the imputer needs to specify which variables should act as predictors in the imputation model. The selection of these predictors is a difficult, but fundamental, step in the MI procedure, especially when there are many variables in a data set. In this project, we explore the use of principal component regression (PCR) as a univariate imputation method in the MICE algorithm to automatically address the many-variables problem that arises when imputing large social science data. We compare different implementations of PCR-based MICE with a correlation-thresholding strategy through two Monte Carlo simulation studies and a case study. We find the use of PCR on a variable-by-variable basis to perform best and that it can perform closely to expertly designed imputation procedures.

Authors: ÜLKERYILDIZ Evren 
Published: August 2023

The disaster of “Covid-19 pandemic” which has been introducing various radical changes on the lifestyle of people such as (1) the usage of urban spaces, (2) spatial problems, (3) the transformation of shared spaces and (4) working practices. These radical changes have been receiving an overwhelming interest from scholars from various disciplines since SARS-CoV-2 corona (i.e., Covid 19) virus set a global pandemic. As a result of this overwhelming interest, a rich but a fragment literature prevails on the radical changes caused by Covid 19 pandemic in built environment studies. The research presented herein explores this rich but fragmented literature on the effects of Covid-19 pandemic by adopting a systematic research design strategy namely bibliometric analysis. It is also discovered that the spatial reorganization response of countries to Covid 19 pandemic to varies from country to country mainly due to the regional characteristics of the countries.
Challenges In The Constructıon Medıatıon
Authors: Arici-Ustuner Yaprak 
Published: August 2023

The construction sector, unlike other sectors, can be defined as a sector where technical competencies are at the forefront, crowded in terms of stakeholders participating in the project process, and open to all kinds of external influences. Therefore, it is possible to experience disputes between the parties during construction projects. Studies in the literature show that this rapid dispute resolution method can be mediation in terms of the construction sector. Mediation can be defined as an impartial third party entering the process and guiding the parties to resolve their dispute. Whether this complex and difficult structure of the construction sector differentiates these mediation processes from the processes of other sectors is not a subject that has been extensively researched in the literature. In this study, which reached 38 mediators, the mediators evaluated their construction mediation processes that they have experienced. As a result of the study, it has been determined that the interest-based structure of the construction sector, involvement of multiple stakeholders in projects and the fact that the disputes in the sector are generally based on technical issues are among the challenges of the mediation processes in the construction sector.

Published: August 2023

Aims: Diagnostic procedures are very important for fetal safety during pregnancy. Magnetic resonance imaging (MRI) is characterized by a higher accuracy rate compared to medical follow-up and post-surgical diagnoses. However, it is very important to use it at the right time in order to maintain cost-effectiveness of the technique. In this study, we aimed to determine the efficacy of MRI in pregnant patients admitted to the emergency department with acute abdominal pain when the etiology has not been defined by other techniques.
Methods: The data of pregnant patients who admitted to the emergency department due to acute abdominal pain between January 2013 and February 2018 were retrospectively analyzed. All these patients evaluated with pelvic magnetic resonance screening, as they could not be diagnosed by physical examination findings, laboratory tests, or ultrasonography. Diagnostic performance of MRI, sensitivity, specificity, and negative and positive predictive values were assessed.
Results: The etiology of the pain was detected in 29 of 57 patients who applied to the emergency department with acute abdominal pain and evaluated with pelvic MRI. The most common cause of acute abdominal pain was acute appendicitis which all of them histopathologically confirmed (n=14). Pelvic abscess, severe hydronephrosis, giant ovarian cyst, pyelonephritis, ovarian torsion, and uterine fibroid torsion were among other causes.
Conclusion: MRI is a highly effective imaging method for diagnosing both acute appendicitis and other pelvic emergencies. Therefore, it would be beneficial for the diagnosis in pregnant patients with acute abdominal pain.

Authors: SEZİKLİ İsmail , ASLAN Orhan , TOPCU Ramazan 
Published: August 2023

Aims: Hemorrhoids is a common anorectal disorder and significantly affects quality of life. Although the number of global studies on hemorrhoids has increased in recent years, there is still no bibliometric study in the literature. In this study, it aimed that analyzing the scientific articles published on hemorrhoids holistically.
Methods: The articles published between 1980 and 2021 were analyzed using bibliometric and statistical methods on hemorrhoids. Network visualization maps were used to identify trending topics and international collaborations. Spearman’s correlation coefficient was used for correlation studies. The Exponential Triple Smoothing estimator was used to estimate the number of articles expected to be published in the coming years.
Results: A total of 3203 publications were found. 1863 (58.1%) of these publications were articles. The most active author is Gupta PJ. (n=26). The first 2 journals that published the most articles were Diseases of the Colon & Rectum (n=228) and Colorectal Disease (n=82). Singapore General Hospital (n=35) and University of Rome La Sapienza (n=19) were the 2 most active institutions. According to the average number of citations per article, the top 2 most influential journals were British Journal of Surgery and American Journal of Gastroenterology.
Conclusion: In this comprehensive study on hemorrhoids, a statistical analysis of 1863 articles was shared. It was determined that the trend topics in hemorrhoid researches were THD, mucopexy, transanal hemorrhoidal dearterialization, colorectal surgery, embolization, constipation, risk factors, Milligan-Morgan, classification, recurrence and randomized controlled trial. This article can be a useful resource for scientists and clinicians in terms of the global output of hemorrhoids yesterday, today and tomorrow.
A bibliometric study of vascularized fibular grafting technique
Authors: YILMAZ Selçuk 
Published: August 2023

Aims: Vascularized fibula graft (VFG) technique is one of these “gold standard” techniques in bone regeneration. Although there have been several bibliometrics studies in orthopedics, there haven’t been any on VFGs. By identifying the gaps in previous research, we sought to provide light on the scientific evolution of VFGs and provide direction for future investigations.
Methods: In this bibliometric study, the Web of Science (WOS) database was used to access publications on VFG published between 1986-2022. A literature search was performed with selected keywords. The dataset obtained was downloaded from the WOS database as an output. This output was analyzed with VOSviewer and Biblioshiny tools.
Results: A total of 430 documents on VFG included the study. A mean of 11.9 articles/year was published on VFG. The first article on VFG published in 1986. Since 2005, there has been an increasing trend in the number of articles and citations. The year with the highest number of both publications (n=32) and citations (n=756) was 2021. The publications on VFG have cited a total of 7300 times, an average of 16.98 citations per publication. Total 51 countries contributed to publications on the VFG between 1986-2022. The United States of America (USA) was identified as the global leader in terms of the number of publications (n=91, 21.163%), followed by Japan (n=58, 13.488%) and China (n=56, 13.023%). The USA had 91 manuscripts and 2162 citations with an H-index:29 and Japan had 58 manuscripts and 1145 citations with an H-index:22.
Conclusion: The literature on VFG is quite limited. Most of the publications are from developed countries. Studies should be supported for this method that can be used in the treatment of many diseases, especially in developing countries.

Abstract
In recent years, automatic classifiers of image cutouts (also called “stamps”) have been shown to be key for fast supernova discovery. The Vera C. Rubin Observatory will distribute about ten million alerts with their respective stamps each night, enabling the discovery of approximately one million supernovae each year. A growing source of confusion for these classifiers is the presence of satellite glints, sequences of point-like sources produced by rotating satellites or debris. The currently planned Rubin stamps will have a size smaller than the typical separation between these point sources. Thus, a larger field-of-view stamp could enable the automatic identification of these sources. However, the distribution of larger stamps would be limited by network bandwidth restrictions. We evaluate the impact of using image stamps of different angular sizes and resolutions for the fast classification of events (active galactic nuclei, asteroids, bogus, satellites, supernovae, and variable stars), using data from the Zwicky Transient Facility. We compare four scenarios: three with the same number of pixels (small field of view with high resolution, large field of view with low resolution, and a multiscale proposal) and a scenario with the full stamp that has a larger field of view and higher resolution. Compared to small field-of-view stamps, our multiscale strategy reduces misclassifications of satellites as asteroids or supernovae, performing on par with high-resolution stamps that are 15 times heavier. We encourage Rubin and its Science Collaborations to consider the benefits of implementing multiscale stamps as a possible update to the alert specification.
AGN’s Deadness Over Cosmic Time: UVJ Diagrams of X-Ray AGN
Authors: Cionitti Rachel , Coleman Brandon , Kirkpatrick Allison , Troiani Greg 
Published: August 2023

Abstract
Over cosmic time, galaxies tend to separate into a bimodal distribution of “red and dead” or blue and star-forming. We examine whether active galaxies evolve in a similar way, and whether this reveals anything about the complexities of the relationship between an AGN and the host galaxy. We use the Stripe82X survey to identify 3940 X-ray AGN spanning z = 0–2.5, and we measure the rest-frame UVJ colors of each galaxy. We classify AGN as star-forming or quiescent based on their location in a UVJ color diagram. We find that there is not a clear bimodal distribution between AGN in star-forming and quiescent galaxies. Furthermore, the most luminous X-ray sources tend to lie in the star-forming region, which may indicate a correlation between central engine activity and increased rates of star formation.

Published: August 2023

Abstract
We compare the evolution of binary systems evolved in the MESA stellar evolution code to those in the COSMIC population synthesis code. Our aim is to convey the robustness of the equations that model binary evolution in the COSMIC code, particularly for the cases of high mass stars with closely orbiting compact object companions. Our larger goal is to accurately model the rates of these systems, as they are promising candidates for the progenitor systems behind energetic, longer lasting, radio bright GRB jets. These systems also may be key contributors to the rates of binary black hole mergers throughout our Universe.
Adaptation et évolution d’un habitat fortifié de l’âge du Bronze en Corse méridionale
Authors: Peche-Quilichini Kewin 
Published: August 2023

Le site d’I Stantari di u Frati è a Sora occupe le sommet et le versant méridional d’une colline culminant à 49 mètres, dans la vallée du Rizzanesi (sud-ouest de la Corse). Sa fouille préventive récente (2019-2020) a révélé une installation perchée, occupée du début du Bronze ancien au Bronze moyen 2. L’habitat est initialement ceinturé par une palissade multiple, puis par un fossé palissadé, enfin par un double mur d’enceinte. Cette évolution traduit le passage graduel entre une implantation du Bronze ancien adaptée à son contexte naturel et une continuation au Bronze moyen plus conforme aux normes architecturales insulaires. Trois habitations de plan elliptique, munies ou non d’un soubassement maçonné, ont été mises en évidence lors des fouilles, révélant des caractères inédits. Leur morphologie permet d’établir des similitudes avec les contextes d’Italie du Sud. Les mobiliers attestent quant à eux de relations avec les microrégions voisines.
Une agglomération protohistorique et antique à Blois (Loir-et-Cher)
Authors: Aubourg Viviane , Josset Didier , Capron François , Simon Gaël 
Published: August 2023

La recherche sur Blois a connu deux grandes étapes, avant et après l’archéologie préventive. Avant, les archéologues proposaient une histoire de la ville antique basée sur des données ponctuelles. Leur interprétation reposait sur un modèle d’organisation classique où seule la rive droite était habitée. Avec le développement de l’archéologie urbaine dans les années 1970, Blois connaît sa première grande fouille. Il faut attendre les années 1990 et la montée de l’archéologie préventive pour proposer de nouvelles interprétations sur l’origine et l’évolution de Blois. La création d’un zonage archéologique, en 2003, tient compte de ces dernières avancées. Dès lors, ce document permet de cibler les zones à investiguer. Depuis, les projets d’aménagement ont conduit à révéler l’histoire de la ville sur ses deux rives, dès l’époque gauloise. Avec la mise en place d’un projet collectif de recherche, en 2013, c’est la ville dans son contexte ligérien qui est désormais étudiée.
Suivi de travaux dans la vallée du Marcadau (Cauterets, Hautes-Pyrénées)
Authors: Berdoy Anne 
Published: August 2023

Un dossier de demande d’autorisation environnementale, liée à la réhabilitation d’un refuge montagnard, a été l’occasion de prescrire une opération d’archéologie préventive. En amont de l’enfouissement d’une canalisation d’eau sur 2,5 km, il s’agissait de réaliser une prospection en vue de reconnaître les vestiges liés à l’occupation agropastorale sur un temps long des pâturages d’altitude impactés par les travaux. Dans un deuxième temps, le creusement de la tranchée a fait l’objet d’un suivi archéologique qui a permis de relever plusieurs structures et niveaux d’occupation. Faute de mobilier archéologique associé, il faudra attendre les résultats des analyses et de l’étude pour disposer d’informations chronologiques. Celles-ci seront en outre complétées par des données paléoenvironnementales.
L’archéologie des villages et petites villes de l’Indre

Published: August 2023

Une archéologie des villages et petites villes actuels s’est développée dans le département de l’Indre depuis ces dernières années. Grâce à une problématisation affinée des opérations d’archéologie préventive et à l’évolution de la prescription, de l’espace effectivement détruit à celui de l’emprise totale de travaux, les interventions de terrain ont permis l’émergence de deux principaux thèmes de recherche : les occupations antérieures au Moyen Âge et les dynamiques des espaces funéraires. Le premier s’est aussi appuyé sur le PCR « Agglomérations secondaires antiques de la région Centre-Val de Loire » et le second sur un réseau informel d’étude des pôles ecclésiaux régionaux.
Du xiie au xxe siècle, une fresque historique à reconstituer à l’abbaye de Noirlac (Cher)
Authors: Kaurin Jenny , Poulle Pascal 
Published: August 2023

La politique de prescription menée depuis la fin des années 2000 vise à mettre en cohérence l’apport de nombreuses décennies de recherche archéologique (fouilles anciennes puis préventives) sur un site emblématique. Les perspectives étaient triples : disposer de l’ensemble des éléments de décision pour accompagner le projet d’aménagement paysager ; valoriser l’apport de l’archéologie à la connaissance de Noirlac  ; penser un outil pouvant orienter la réflexion sur les aménagements futurs.
Les jeunes années de l’archéologie préventive en mer
Authors: Schaumasse Arnaud , Fontaine Souen 
Published: August 2023

Grâce aux acquis méthodologiques des dernières années et à la clarification du cadre législatif et fiscal, une part non négligeable du patrimoine sous-marin susceptible d’être détruit par un aménagement ou l’exploitation de la mer, a été rendue lisible. Il reste toutefois un saut qualitatif comme quantitatif à faire pour conforter dans le paysage scientifique, sous les eaux comme elle l’est sur terre, une archéologie préventive définitivement libérée des charges et des pratiques du sauvetage. Aux enjeux de l’archéologie préventive en mer font écho ceux de celle opérée dans les eaux intérieures, fluviales et lacustres. Bien qu’elle n’ait pas connu les mêmes aléas normatifs, elle accuse un même retard dans son application, des difficultés d’instruction des dossiers à la mise en œuvre de terrain. Composantes essentielles de nos paysages, les cours d’eau et les étendues d’eau ont été exploités, aménagés, empruntés et franchis à travers les âges. La dynamique d’aménagements prévus pour la décennie en cours va nécessairement avoir un impact fort sur des sites archéologiques encore méconnus, quand ils ne sont pas simplement invisibilisés, que seule une action concertée — et renforcée par des moyens conséquents — des différents acteurs de l’archéologie et de l’inventaire du patrimoine permettra de prendre en compte.
Le complexe archéologique d’Aléria. De l’archéologie préventive au musée
Authors: Tristani Julia , Bontempi Jean-Michel , Vidal Laurent 
Published: August 2023

Redonner au musée d’Aléria une dimension à la hauteur de sa collection constituée depuis les années 1950 apparaît comme une évidence. Un long, mais nécessaire, travail préalable a été mené, permettant la mise en place des structures destinées à la bonne marche du triptyque étude / conservation / valorisation. Il s’est concrétisé, notamment, par l’ouverture en 2014 de l’un des premiers Centres de Conservation et d’Études (CCE). Au cours des années à venir, la collection d’Aléria sera remise dans son contexte à la lumière des découvertes récentes, recréant le lien, pour la période étrusque notamment, entre les nécropoles et les zones dédiées à l’habitat et aux productions. Les relations entretenues par les opérateurs de terrain et les gestionnaires patrimoniaux au cours de ces travaux permettent immédiatement d’intégrer les résultats de ces derniers dans une démarche d’exploitation scientifique des collections « anciennes » du musée et de conservation pérenne des nouveaux mobiliers mis au jour par l’archéologie préventive. Ceci nécessite d’évaluer le potentiel archéologique du riche sous-sol du hameau du Fort de Matra et des demandes de diagnostics anticipés ont été adressées à la Drac de Corse. Cette intense activité impliquera au cours des mois et années à venir une interaction à nouveau très riche entre les acteurs de l’archéologie préventive et ceux de l’univers muséal.

Published: August 2023

Background
Eltrombopag (EPAG) was recently approved for aplastic anemia (AA). The recommended regimen is triple agents, EPAG, anti-thymocyte globulin, and cyclosporin A (CsA). Anti-thymocyte globulin is not available in many centers and has serious adverse effects.

Aim
This study assessed, for the first time, two-agent therapies comprising EPAG+CsA in patients with AA.

Patients and methods
Group A included 33 patients with AA who were treated with EPAG+CsA and prospectively recruited. Their health-related quality of life (HRQoL) was assessed. All parameters were evaluated at enrollment and after 2−3 months. Bone marrow aspirate was done after 6 months. Another 33 patients who received CsA only (group B) were retrospectively recruited for comparison.

Results
Both groups were matched regarding demographic and baseline hematologic profile. Significant increment and reduction, after treatment, of absolute neutrophil count and platelets, and transfusion requirements, were respectively seen in group A compared with group B, whereas mean platelet volume was significantly increased in group A only (0.025). The overall response rate and complete remission rate were 72.7 vs. 45.5% and 15.1 vs. 3% in groups A and B, respectively. Significant improvement of the total RAND scoring was found in HRQoL items of group A; however, the social functioning score did not improve significantly. Therapeutic response to EPAG+CsA was an independent effector of HRQoL. After 6 months, one patient had acute leukemia and another one developed fibrosis.

Conclusions
A ramp-up, short-duration, therapy with EPAG+CsA in AA is as effective as fixed-dose triple agents, with lower risk of disease progression or fibrosis.
