In the Shadow of the Queen: On UNESCO’S Universal History, the Women of the Petit Trianon, and Tourist Meaning-Making
Authors: Paige-Lovingood Mandy 
Published: February 2022

Abstract
Upon the designation of Versailles as a World Heritage Site, UNESCO renamed the Petit Trianon the Domaine de Marie-Antoinette (Estate of Marie-Antoinette). Subsequent tourist materials, such as travel guides and website directories, reiterated this redesignation and retell the site’s historical past through the life of Marie-Antoinette, thereby casting Madame de Pompadour and the Comtesse du Barry to the periphery. This essay analyzes visitor Instagram photos and Tripadvisor reviews to understand how UNESCO’s uniting of the queen’s memory with the Petit Trianon affects tourist interpretation and meaning making. It considers the consequences of the universalization of a single narrative to recount a multi-actor history and highlights the continued erasure of Madame de Pompadour and Comtesse du Barry taking place in visitors’ retelling of the Petit Trianon’s past.
Representing the Other and the Democratization of History. Polish Reenactors in Nazi Uniforms
Authors: Baraniecka-Olszewska Kamila 
Published: February 2022

Abstract
Through a case study of the World War II reenactment movement in Poland, this article analyzes the relationship between the processes of the democratization of history and the normalization of the Nazi past. There are numerous groups whose members dedicate their time to represent Wehrmacht or Waffen-SS units and do so in the public while reenacting battles or restaging historical events. Despite the dominant moral attitude which condemns representing troops that committed war crimes and atrocities, reenactors defend their hobby, offering an alternative, in their opinion, moral and critical way of engaging with the Nazi past. The author argues that presenting views on WWII in the public sphere is possible due to the process of the democratization of history. However, she also demonstrates that the very same process means that reenactors’ efforts are misunderstood by their audiences. Also, these reenactment practices have contributed to normalizing the Nazi past.
Ultrasonographic measurements of the testicular volume in Turkish boys aged 0–8 years and comparison with international references
Authors: Çolak Edis , Özkan Behzat 
Published: February 2022

Abstract

Objectives
Proper diagnosis and follow-up of children with testicular disorders depend on the presence of adequate references for testicular volume. The objective of this study was to determine the testicular volume by ultrasound in Turkish boys aged between 0 and 8 years.

Methods
A total of 320 boys with bilaterally descended testes underwent scrotal ultrasound examinations. The testicular volume (mL) was calculated by the empirical formula of Lambert (V=L × T × AP × 0.71) and the formula for an ellipsoid (V=L × T × AP × π/6). The testicular volume was compared with children’s age, and Z-score data for weight, height, and BMI. The age-specific 3rd, 10th, 25th, 50th, 75th, 90th, and 97th percentiles of the testicular volume were produced and compared with the international references.

Results
The median (IQR) volume of the right and left testis were 0.75 (0.57–0.99) and 0.72 (0.56–0.98) mL (formula of Lambert), respectively; and 0.56 (0.42–0.73) and 0.53 (0.41–0.72) mL, (formula for an ellipsoid), respectively. The age-specific median of the average volume of the right and left testis estimated by the Lambert equation in the first five years was measured between 0.63 and 0.71 mL, followed by an increase to about 1.31 mL at the age of 8. This increase was highly statistically significant (p<0.0001). No significant association was found between the Z-scores for weight, height, and BMI of boys and the testicular volumes.

Conclusions
This study provides the first national ultrasound-based estimates for testicular volume in Turkish boys aged 0–8 years.
Postpartum depression, mode of delivery, and indication for unscheduled cesarean delivery: a retrospective cohort study
Authors: Lantigua-Martinez Meralis , Silverstein Jenna S. , Trostle Megan E. , Melendez Torres Anthony , Rajeev Pournami , Dennis Alyson , Talib Mahino 
Published: February 2022

Abstract

Objectives
To examine the relationship between postpartum depression (PPD), mode of delivery (MOD), and indication for unscheduled cesarean delivery (uCD).

Methods
Patients with antenatal and postpartum Edinburgh Postnatal Depression Scale (EPDS) scores were compared by MOD and indication for uCD if applicable. Patients with an antenatal EPDS>12 were excluded to ascertain the incidence of new depression. The primary outcome was EPDS≥13 by MOD. The secondary outcome was EPDS≥13 by indication for uCD.

Results
Seven hundred and thirty eight patients met inclusion criteria. There were statistically significant differences in MOD by age, race, BMI, and multi-gestation pregnancy. Patients delivered via uCD had a higher rate of peripartum complications and NICU admission. There were no differences in medical comorbidities or use of psychiatric medications by MOD. There was no difference in EPDS by MOD. The rate of PPD was higher in patients with uCD for non-reassuring fetal heart tones (NRFHT) compared to other indications for uCD (p=0.02).

Conclusions
While there was no difference in the incidence of PPD by MOD, the incidence of PPD was higher among patients delivered via uCD for NRFHT. These findings may have implications for patient counseling, post-operative mental health surveillance, and support of postpartum patients.
lncRNA ACTA2-AS1 inhibits malignant phenotypes of gastric cancer cells

Published: February 2022

Abstract
Gastric cancer (GC) is one of the most common malignancies in digestive system. Accumulating evidence reveals the critical role of long noncoding RNAs (lncRNAs) in GC development. The study aimed to explore the functions and mechanism of lncRNA actin alpha 2, smooth muscle antisense RNA 1 (ACTA2-AS1) in GC. Reverse transcription-quantitative polymerase chain reaction analyses and subcellular fractionation assays showed that ACTA2-AS1 was lowly expressed in GC cells and was mainly distributed in the cytoplasm. Overexpressed ACTA2-AS1 inhibited GC cell viability, proliferation, migration, invasion, and epithelial-mesenchymal transition process, as suggested by cell counting kit-8 assays, colony formation assays, wound healing assays, Transwell assays and Western blot analyses. Mechanistically, ACTA2-AS1 served as a competing endogenous RNA (ceRNA) to bind with miR-378a-3p and thereby, antagonized the inhibitory effect of miR-378a-3p on the expression of messenger RNA phosphatidylinositol specific phospholipase C X domain containing 2 (PLCXD2). The binding capacity between miR-378a-3p and ACTA2-AS1 (or PLCXD2) was detected by RNA pulldown assays, luciferase reporter assays and RNA immunoprecipitation assays. Moreover, PLCXD2 knockdown rescued the inhibitory effect of ACTA2-AS1 overexpression on malignant behaviors of GC cells. Overall, ACTA2-AS1 inhibits malignant phenotypes of GC cells by acting as a ceRNA to target miR-378a-3p/PLCXD2 axis.

Spatiotemporal optical vortices with arbitrary orbital angular momentum orientation by astigmatic mode converters
Authors: Zang Yimin , Mirando Amal , Chong Andy 
Published: February 2022

Abstract
We generate a spatiotemporal optical vortex (STOV) with tunable orbital angular momentum (OAM) orientation by a simple lens system. We utilize a cylindrical lens system, which is an astigmatic mode converter, to add longitudinal angular momentum to tilt the purely transverse OAM in an arbitrary direction. The amount of tilt is tunable by adjusting the lens system, and thus the OAM direction is continuously adjustable. STOVs with adjustable OAM directions have been verified theoretically and experimentally. We believe such direction controllable OAMs will enrich future applications.
Fundamental limits and design principles of doublet metalenses
Authors: Martins Augusto , Li Juntao , Borges Ben-Hur V. , Krauss Thomas F. , Martins Emiliano R. 
Published: February 2022

Abstract
Metalenses are nanostructured surfaces with great potential for delivering miniaturized and integrated optical systems. A key property of metalenses is that, by using a double layer configuration, or doublet, they can achieve both diffraction-limited resolution and wide field-of-view imaging. The physical operation and limitations of such doublet systems, however, are still not fully understood, and designs are still based on numerical optimization of the phase profiles. Here, we show the fundamental limits of doublet systems and provide a universal design strategy without any need to resort to numerical optimization. We find an analytical relationship between the focal length and the spacer thickness; we identify the physical principles underlying the limitations on performance and obtain a universal dependence of the field of view as a function of resolution (numerical aperture). Our results will allow researchers to appreciate the regimes of resolution and field of view that are accessible for specific applications, to identify the conditions for optimum performance (such as required spacer thickness), and to conveniently design doublets without needing to resort to numerical optimizations.

Numerical investigation of ozone decomposition by self-excited oscillation cavitation jet
Authors: Li Hongmin , Liu Jingting , Chen Songying , Lv Wei 
Published: February 2022

Abstract
Extreme environmental changes caused by the cavitation bubble collapse, such as high pressure, high temperature and the microjet, will cause pyrolysis reaction at the gas and liquid interface inside the bubble. Self-excited pulsed cavitation jet has an instantaneous strong pulse pressure, which leads to local hot spots surrounding the cavitation bubbles. The generation of strong oxidizing free radicals promotes easy ozone conversion into oxygen. Numerical simulations were conducted for ozone decomposition by cavitation jet. Three groups of different collision angles were applied to compare and analyze the ozone degradation reaction. Results showed that the collision angle has a certain influence on the chemical reaction intensity, the degradation of ozone, and oxygen production. At the collision angle of 180°, the chemical reaction was the most violent, with ozone degradation and oxygen production at the highest level, followed by 120° and lowest at 90°.

“Together we can all make little steps towards a better world”: interdiscursive construction of ecologically engaged voices in YouTube vlogs
Authors: Sokół Małgorzata 
Published: February 2022

AbstractDrawing on the resources of Ecolinguistics and Positive Discourse Analysis, this paper investigates the interdiscursive practices that lifestyle vloggers engage in to construct their expertise and credibility when performing eco-activism. The analysis of the corpus of 30 YouTube vlogs promoting a sustainable lifestyle reveals the interplay of cross-generic conventions that young adult YouTubers employ to manage their lay expertise. Their mediated activist talk mixes basic text types of narration, argumentation, exposition and instruction with self-disclosure, technical and colloquial talk as well as social and promotional discourses. In this way, the vloggers exploit the affordances of the medium to construct the new stories of consumerism and everyday, ‘ordinary’ eco-activism based on private, green lifestyle choices. The vloggers’ interdiscursive talk and the presence of credibility strategies in the data may have an empowering effect on the audience. For one thing, the vloggers position their audience as actors who are capable of making effective choices on their way to a sustainable life. For another, empowerment is accomplished through the transformation of the vloggers’ private experience into public discourse that members of the audience can find relevant and meaningful. Overall, the study points to the potential of interdiscursive practices in the vlog as a ‘positive’ linguistic resource that can encourage people to protect our ecosystems.

Abstract
PrCa4O[BO3]3 was grown as a single crystal by the Czochralski method. The precursor material was synthesized by solid state reaction under O2 atmosphere and sintered after grinding under N2 atmosphere with a content of 20% H2. The Czochralski crystal growth proceeded under N2 atmosphere with an <010> oriented GdCa4O[BO3]3 crystal seed. A PrCa4O[BO3]3 crystal with a cylinder length of 20 mm, a diameter of 15 mm, and weight of 23.1 g was obtained. The crystal structure was solved from single crystal X-ray diffraction data in the monoclinic crystal system with space group C1m1 (No. 8), the lattice parameters a = 8.1293(6) Å, b = 16.062(1) Å, c = 3.6023(2) Å, β = 101.371(2)°, formula units of 2 and final R- and wR2-values below 3.8%. A mixed occupancy between Pr and Ca of 6.0% was found.
