Une collecte d’images
Authors: Haug Steffen 
Published: June 2022

Entre 1927 et 1930 à Berlin, puis de 1934 à 1940 à Paris, Walter Benjamin travaille à accumuler des matériaux pour un projet de vaste envergure : retracer, à partir de l’étude des passages parisiens, une « préhistoire du XIXe siècle ». La rédaction du texte est sans cesse différée, tandis que l’immense corpus préparatoire semble voué à croître indéfiniment, devenant une somme composite de citations que double parfois, à la manière d’une note de régie, une réflexion ou une remarque énigmatique.Au fil de ses recherches, Benjamin se rend à l’évidence : il faudra que son Livre des passages soit enrichi par des images. Une « documentation visuelle » se constitue bientôt, écrit-il, glanée pour l’essentiel dans les recueils du Cabinet des estampes de la Bibliothèque nationale où il travaille pendant son exil parisien. Une centaine de notes témoignent de cette collecte et conservent, enfermée dans leurs plis, la mention d’une ou de plusieurs images qui sont restées pour la plupart inconnues jusqu’ici.Steffen Haug a voulu retrouver cette réserve enfouie. Gravures et dessins de presse, tracts, réclames, affiches et photographies, de Meryon et Grandville à Daumier, en passant par la cohorte anonyme et le tout-venant de la production visuelle à grand tirage du XIXe siècle : la moisson rapportée ici est surprenante. Elle invite à lire ou relire les Passages en faisant à l’image toute la place qu’elle occupe dans la pensée du dernier Benjamin, à l’heure où s’élaborent, sous la menace de temps assombris, son essai « L’œuvre d’art à l’époque de sa reproductibilité technique », le projet de livre sur Baudelaire ou ses Thèses sur le concept d’histoire.
Influence of Optimum Torque Reverse Motion on Dentinal Cracks after Root Canal Preparation with Two Nickel-Titanium Rotary Systems
Authors: Khallaf Maram , Hassan Reham 
Published: June 2022

Objectives:
This study was aimed to evaluate the cause-effect relationship between canal preparation with ProTaper Next (PTN) and ProTaper Gold (PTG) using optimum torque reverse (OTR) motion or continuous rotation and dentinal crack formation.

Materials and Methods:
Fifty distobuccal roots of human maxillary first molars were divided into five groups; Group I: PTG Full rotation, Group II: PTG in OTR, Group III: PTN Full rotation, Group IV: PTN in OTR, Group V: unprepared (control group). After mechanical preparation, the distobuccal roots were sectioned horizontally at 3, 6, and 9 mm from the apex. Images were captured using a stereomicroscope at 25X to determine the presence or absence of dentinal cracks. Friedman test was used to compare between root sections followed by Wilcoxon signed-rank test for pairwise comparison. Kruskal–Wallis test was used to compare between tested rotary systems followed by pairwise comparison with Dunn Bonferroni correction (α = 0.05).

Results:
Crack development was significantly higher in PTG using OTR motion 36.7% followed by PTN using OTR 33.3%, while the control group showed no cracks. PTG and PTN with full rotation showed crack development with 23.3% and 13.3%, respectively.

Conclusions:
The type of motion kinematics used during mechanical preparation have an impact on dentinal crack formation. Nickel-titanium instruments with larger taper tend to induce more cracks.
Assessment of Implant-Related Anatomical Landmarks in the Mandibular Interforaminal Region in an Iranian Population Using Cone-Beam Computed Tomography
Authors: Nikkerdar Nafiseh , Golshah Amin , Mahmoodivesali Razieh , Falah-Kooshki Sepideh 
Published: June 2022

Background:
This study was aimed to assess the implant-related anatomical landmarks in the mandibular interforaminal region in an Iranian population using cone-beam computed tomography (CBCT).

Methods:
In this retrospective cross-sectional study, 378 CBCT images of the mandible were evaluated for the presence of the incisive canal, anterior loop of the inferior alveolar nerve (IAN), mandibular canal, mental foramen, and incisive canal. The effect of age and gender of patients on the abovementioned variables was also evaluated. Data were analyzed using independent t-test, analysis of variance, and Chi-square test.

Results:
The anterior loop and the incisive canal were present in 36.24% and 97.62% of the cases, respectively. The mean length of the anterior loop and the incisive canal was 2.70 ± 1.20 mm and 12 ± 3.29 mm in the right, and 2.86 ± 1.24 mm and 12.21 ± 3.38 mm in the left side, respectively. The mean diameter of the mental foramen and incisive canal was 4.25 ± 1.08 mm and 1.89 ± 0.46 mm in the right, and 4.21 ± 1.02 mm and 1.94 ± 0.45 mm in the left side, respectively. The descending path was the most common path of the incisive canal. The distance from the incisive canal to the buccal plate and inferior border of the mandible was significantly shorter in females (P < 0.001).

Conclusion:
Considering the high variability and clinical significance of the incisive canal and anterior loop of the IAN, and their high prevalence, it is recommended to assess the presence/absence of these structures in the interforaminal region of the mandible on CBCT scans before surgical procedures in this region.

Published: June 2022

Objective:
The objective is to determine the prognostic factors affecting the surgical outcome of patients surgically treated for acute epidural haematoma.

Materials and Methods:
A retrospective review of 71 consecutive patients who underwent neurosurgery for acute epidural haematomas over a 5-year period (from January 2015 to December 2019) was conducted. Clinical characteristics and the time intervals were investigated to determine the interactions between all these factors and the outcome. The outcome was graded according to the Glasgow Outcome Scale (GOS) at subsequent follow-up clinic visits.

Results:
The severity of traumatic brain injury using the Glasgow Coma Scale score (chi-square test, P = 0.033) had a statistically significant relationship with the outcome. The patients’ age, gender, and total length of time until surgical intervention (P > 0.05) were of no statistical significance in relation to the outcome. The mortality rate of patients presenting at our centre is 16.9%. Overall, after surgery, 47 of 71 with epidural haematoma had good recovery (GOS 5). Twelve of 71 patients had GOS of 2–4. Twelve patients died. The median duration from injury to presentation was 15 hours with an interquartile range of 15 hours.

Conclusion:
Our results indicate that the severity of brain injury is an independent risk factor in determining the outcome of epidural haematoma in traumatic brain injury.
Quivers with potentials for Grassmannian cluster algebras
Authors: Chang Wen , Zhang Jie 
Published: June 2022

AbstractWe consider a quiver with potential (QP)
$(Q(D),W(D))$
and an iced quiver with potential (IQP)
$(\overline {Q}(D), F(D), \overline {W}(D))$
associated with a Postnikov Diagram D and prove that their mutations are compatible with the geometric exchanges of D. This ensures that we may define a QP
$(Q,W)$
and an IQP
$(\overline {Q},F,\overline {W})$
for a Grassmannian cluster algebra up to mutation equivalence. It shows that
$(Q,W)$
is always rigid (thus nondegenerate) and Jacobi-finite. Moreover, in fact, we show that it is the unique nondegenerate (thus rigid) QP by using a general result of Geiß, Labardini-Fragoso, and Schröer (2016, Advances in Mathematics 290, 364–452).Then we show that, within the mutation class of the QP for a Grassmannian cluster algebra, the quivers determine the potentials up to right equivalence. As an application, we verify that the auto-equivalence group of the generalized cluster category
${\mathcal {C}}_{(Q, W)}$
is isomorphic to the cluster automorphism group of the associated Grassmannian cluster algebra
${{\mathcal {A}}_Q}$
with trivial coefficients.
Is Lobbying Effictively Regulated in the Regional Self-governments in Poland? The Cases of Opolskie and Podkarpackie Regional Self-governments
Authors: Olejnik Maciej 
Published: June 2022

The goal of the paper is to examine whether lobbying is effectively regulated in the regional self-governments in Poland. The article analyses two cases: Opolskie and Podkarpackie regional self-governments (2014-2020). For the purpose of the article, three types of material were gathered 1) A legislation regulating lobbying in Poland (the Law on Lobbying); 2) The results of the semi-structured interviews with sixty councilors from both regional chambers; 3) The websites and public social media accounts of the legislators and major lobbyists and the correspondence with heads of the regions’ organizational departments. Two scientific methods were adopted (institutionally-legal analysis and comparative method) to examine the material.
An outcome of the research revealed that lobbying is ineffectively regulated. A law does not provide the state with instruments allowing to control the prevailing type of lobbying (“lobbying activity”). Furthermore, neither councilors, nor lobbyists adopted ethical codes of conduct that would establish clear behavioral standards. Moreover, lobbyists have equal access only to the rank-and-file councilors, whereas solely the strongest ones can contact the legislators constituting the regional government.
The Problem of the Admissibility of Modifications to Public Procurement (and Concession Contracts)
Authors: Mužina Aleksij 
Published: June 2022

The central part of the scientific article is the analysis of the problem of the admissibility of modifications of public procurement contracts and concession contracts. After the awarding of a concession or a public procurement contract, these may not be substantially changed by an agreement between the contracting authority and the successful tenderer. The research is initially focused to an analysis of the development of the legal institute in the case law of the Court of Justice and its transposition into secondary legislation of the European Union. This is followed by a comparison of the regulation in the acquis communautaire with the regulation in Slovenian positive law. The problems of the admissibility of modifications to public procurement contracts/concessions (this is the central part of the article) should be supplemented by formulating a thesis on the possible extension of comparable standards of interpretation of admissibility from the contractual (implementation) to the tendering stage of public procurement/concession.
In this scientific paper, I therefore point out (which was the purpose of the scientific paper) the hypothesis that all modifications in public procurement procedures and concession award procedures must be treated equally, regardless of the stage a relationship creation or implementation process. A different position would be administrative and contrary to the necessary functional interpretation of EU law. The modification cannot becomes admissible at the time of the conclusion of the contract, while prior to that, this modification (which would already form part of the contractual relationship) is not admissible.

Anxiety disorders are one of the most prevalent class of mental disorders in the general population. Generalized anxiety disorder (GAD) is a common anxiety disorder that comprises continuous and long-lasting worrying, tension, which making normal life problematic and relaxation impossible
The prevalence rate of GAD disorder is increasing constantly in modern era. Though many different types of modern medications used currently to treat anxiety disorders provide temporary relief, they come with various side effects, Drug dependence and safety concerns. In Ayurveda the symptoms of this disease show resemblance with the condition. Cittodvega (excited state of mind) which is one among the Manovikara in Ayurveda caused by dysfunction of increased Vata and Pitta dosha.
The present study was conducted as an Uncontrolled clinical trial to study the Efficacy of Drakshadi Phantam in 38 diagnosed participants of Generalized Anxiety Disorder with the age group 20–50 were administered with 100ml of Drakshadi Phantam twice daily before food continuously for a period of 45 days.
Five assessments were done staring from 0th day of treatment to 60 the day of the study with a gap of 15 days, using Hamilton anxiety rating scale and Rajas Tams rating scale. The assessment scores of different intervals were statistically analysed using RM ANOVA. Effect of the therapy were statistically analysed in each domain of HAM – A rating scale in different intervals of the study. The therapy was found statistically significant in reducing the symptoms of GAD in all the 14 domains of the HAM- A Rating scale.
Based on results it has been concluded that Drakshadi Phantam has statistically significant effect in reducing the symptoms of all the 14 domains of Hamilton anxiety rating scale and reducing the Rajasika and Tamasika qualities of the study participants.
A Comparative History of Local Resilience?
Authors: Egry Gábor 
Published: June 2022

The classic accounts of the history of the Habsburg Empire emphasized the importance of the conflict of nationalities and alleged that national oppression was the root cause of the Empire’s dissolution in 1918. Based on new results, however, the Nepostrans ERC project has raised two important issues: caution against the idea of all-pervasive nationalisms, and the perspective that the disappearance of Austria–Hungary was not a clear and sharp break and that continuities were just as important as ruptures. Built on concepts like ‘phantom boundaries’ (Phantomgrenzen) and New Imperial History, the focus of the Nepostrans ERC project is a dual one. The first aspect centers on the transformation of imperial society, governance, and institutions that emerged due to the war effort, and the second on the transition out of the imperial framework as the key consequence of the latter, with special attention given to social and institutional consequences and the enabling of new statebuilding efforts at a local level. The fundamental issues addressed by the project—running from 2018 to 2023—are the various relations between statehood and society at the local and regional levels that are examined in nine cases: Tyrol, Hradec Králové (Königrätz), southern Banat, Znojmo (Znaim), Prekmurje (Muravidék), Rijeka (Fiume), Kolomiya (Kolomea), Baia Mare (Nagybánya), and the outskirts of Budapest. The cases were primarily selected to represent typical variations in the social and political configuration during investigated period, 1917–1930.
The Effect of Asymmetric Information on the Pricing of Equity Issuance
Authors: Shahhosseini Mehrnoush 
Published: June 2022

Purpose: This paper examined the adverse selection in the market for seasoned equity issuance.
Methodology: The asymmetric information explained the price reduction at the date of equity issuance. In particular, equity issuance tended to follow credible information releases since companies issued equity when the market was the most informed about the quality of their firms. The paper exploited brokerage mergers as a quasi-natural experiment that increased information asymmetry through their effect on the extent of research coverage by sell-side equity analysts.
Findings: The broker mergers unexpectedly terminated brokers operation, and the level of analyst coverage decreased for the firms previously covered by these analysts. This paper showed that the cumulative abnormal return was positive around the date of equity issuance when asymmetric information increased and more substantial for stocks that lost analyst coverage relative to the stocks that never lost any coverage. Moreover, affected companies by the brokerage mergers issued more equity after the events compared to the control group. This paper showed the causal impact of losing analyst coverage on price at the time of equity issuance.

Published: June 2022

Abstract
Importance: Psychometric examinations for patients with stroke remain insufficient. The Center for Epidemiologic Studies Depression Scale (CES–D), Beck Depression Inventory–II (BDI–II), and Geriatric Depression Scale (GDS) are promising outcome measures.
Objective: To examine and compare the reliability and validity of three depression measures in a sample of patients with stroke.
Design: Repeated-measures design.
Setting: A hospital in southern Taiwan.
Participants: Fifty-nine outpatients, who completed three depression measures.
Outcomes and Measures: Cronbach’s α and intraclass correlation coefficients (ICCs) were used to examine the internal consistency and test–retest reliability, respectively, of the three measures. An independent-samples t test was conducted to compare two groups of patients with different levels of disability to investigate discriminative validity. Pearson’s rs were calculated among the three measures to examine concurrent validity.
Results: The three measures had good internal consistency (α = .85–.92) and sufficient test–retest reliability (ICC = .84–.91). The minimal detectable change (percentage of minimal detectable change) was 10.6 (63.3%), 13.5 (98.3%), and 5.8 (49.9%) for the CES–D, BDI–II, and GDS, respectively. There was a statistically significant difference between the two groups in CES–D score (p = .032) and no significant differences on the other two measures (p = .095–.187). The correlations among the three measures ranged from .79 to .89.
Conclusion and Relevance: All three depression measures had sound internal consistency, test–retest reliability, and concurrent validity in patients with stroke.
What This Article Adds: Of the three measures, the CES–D had better discriminative validity, and the GDS demonstrated greater reliability and smaller random measurement error in patients with stroke.

PurposeObjective of this study was to compare high-pitch prospective electrocardiogram (ECG)-gated computed tomography (CT) pulmonary angiography (HP-PECG-gated CTPA) with standard-pitch non-ECG-gated CT pulmonary angiography (SP-NECG-gated CTPA) on 128-slice dual-source CT (DSCT) for the detection of subsegmental pulmonary embolism (SSPE) in patients suspected of acute pulmonary embolism (APE) with radiation and contrast-optimized protocols. Cardiac-related motion artefacts, lung image quality, and quantitative parameter (pulmonary arterial enhancement, radiation exposure, and contrast) volumes were also compared.Material and methodsThis prospective study enrolled 87 patients clinically suspected of APE and randomly distributed to either group by software. Two radiologists blinded to each other interpreted the images for assessment of SSPE, image quality, and quantitative parameters.ResultsSSPE was diagnosed in 15/44 (34.09%) patients in HP-PECG-gated CTPA, in comparison to 8/43 (18.60%) patients in SP-NECG-gated CTPA. Cardiac motion-related artefacts (blurring of bronchovascular structures and double-line artefacts) were statistically significantly less, with p-value < 0.05. Lung image quality was also better, with p-value < 0.001. Effective radiation dose and contrast volume in HP-PECG-gated CTPA were (2.54 ± 0.80 mSv, 45.05 ± 6 ml) versus SP-NECG-gated CTPA (3.17 ± 1.20 mSv, 74.19 ± 7.63 ml) with p-values of 0.007 and 0.001, respectively.ConclusionsRadiation and contrast volume-optimized HP-PECG-gated CTPA provides reduced cardiac motion related artefacts of pulmonary arteries, which allows enhanced detection of SSPE. It also provides better image quality of lung and parenchyma with lower radiation exposure and less contrast volume.
