Identification of a cantilever beam’s spatially uncertain stiffness
Authors: Hoppe Karl-Alexander , Kronthaler Martin G. T. , Sepahvand Kian , Marburg Steffen 
Published: January 2023

AbstractThis study identifies non-homogeneous stiffnesses in a non-destructive manner from simulated noisy measurements of a structural response. The finite element method serves as a discretization for the respective cantilever beam example problems: static loading and modal analysis. Karhunen–Loève expansions represent the stiffness random fields. We solve the inverse problems using Bayesian inference on the Karhunen–Loève coefficients, hereby introducing a novel resonance frequency method. The flexible descriptions of both the structural stiffness uncertainty and the measurement noise characteristics allow for straightforward adoption to measurement setups and a range of non-homogeneous materials. Evaluating the inversion performance for varying stiffness covariance functions shows that the static analysis procedure outperforms the modal analysis procedure in a mean sense. However, the solution quality depends on the position within the beam for the static analysis approach, while the confidence interval height remains constant along the beam for the modal analysis. An investigation of the effect of the signal-to-noise ratio reveals that the static loading procedure yields lower errors than the dynamic procedure for the chosen configuration with ideal boundary conditions.
Investigating ethanol production using the Zymomonas mobilis crude extract
Authors: Aminian Amirhossein , Motamedian Ehsan 
Published: January 2023

AbstractCell-free systems have become valuable investigating tools for metabolic engineering research due to their easy access to metabolism without the interference of the membrane. Therefore, we applied Zymomonas mobilis cell-free system to investigate whether ethanol production is controlled by the genes of the metabolic pathway or is limited by cofactors. Initially, different glucose concentrations were added to the extract to determine the crude extract's capability to produce ethanol. Then, we investigated the genes of the metabolic pathway to find the limiting step in the ethanol production pathway. Next, to identify the bottleneck gene, a systemic approach was applied based on the integration of gene expression data on a cell-free metabolic model. ZMO1696 was determined as the bottleneck gene and an activator for its enzyme was added to the extract to experimentally assess its effect on ethanol production. Then the effect of NAD+ addition at the high concentration of glucose (1 M) was evaluated, which indicates no improvement in efficiency. Finally, the imbalance ratio of ADP/ATP was found as the controlling factor by measuring ATP levels in the extract. Furthermore, sodium gluconate as a carbon source was utilized to investigate the expansion of substrate consumption by the extract. 100% of the maximum theoretical yield was obtained at 0.01 M of sodium gluconate while it cannot be consumed by Z. mobilis. This research demonstrated the challenges and advantages of using Z. mobilis crude extract for overproduction.

Published: January 2023

AbstractThe most precise measurement tools of humankind are equipped with ultra-stable lasers. State-of-the-art laser stabilization techniques are based on external cavities, that are limited by noise originated in the coatings of the cavity mirrors. Microstructured mirror coatings (so-called meta-mirrors) are a promising technology to overcome the limitations of coating noise and therewith pave the way towards next-generation ultra-stable lasers. We present experimental realization of a 12,000-finesse optical cavity based on one low-noise meta-mirror. The use of the mirrors studied here in cryogenic silicon cavities represents an order of magnitude reduction in the current limiting mirror noise, such that the stability limit due to fundamental noise can be reduced to 5 × 10−18.
Systematic Analysis of Language Transcripts Solutions: A Tutorial
Authors: Heilmann John , Miller Jon F. 
Published: January 2023

Purpose:
In the early 1980s, researchers and speech-language pathologists (SLPs) collaborated to develop the Systematic Analysis of Language Transcripts (SALT). Research and development over the ensuing decades has culminated into SALT Solutions, a set of tools to assist SLPs to efficiently complete language sample analysis (LSA) with their clients. In this tutorial, we describe how SALT can assist with the accurate identification of children with language disorders and provide a rich description of children's functional language use. After summarizing the multiple elicitation methods developed by the SALT team, we provide case studies, showing how to select an elicitation method that aligns with a child's characteristics. We then summarize major considerations when transcribing, analyzing, and interpreting language samples with SALT. We revisit our case studies to illustrate how SALT adds value to the comprehensive assessment of language in children.

Conclusions:
LSA is a powerful assessment tool for children suspected of having language disorders. The SALT suite of solutions provides a toolkit to assist SLPs with their comprehensive language assessments.

Context. Recent studies have shown that 6.7 GHz methanol maser flares can be a powerful tool for verifying the mechanisms of maser production and even the specific signatures of accretion rate changes in the early stages of high-mass star formation.
Aims. We characterize the spatial structure and evolution of methanol and water masers during a flare of methanol maser emission at 6.7 GHz in the high-mass young stellar object (HMYSO) G24.33+0.14.
Methods. Very Long Baseline Array (VLBA) was used to image the 6.7 and 12.2 GHz methanol and 22.2 GHz water vapor masers at three epochs guided by monitoring the methanol line with the Torun 32m telescope. The 6.7 GHz maser maps were also obtained with the European VLBI Network (EVN) and Long Baseline Array (LBA) during the flare. The Wide-field Infrared Survey Explorer (WISE) data were used to find correlations between the 6.7 GHz maser and infrared (IR) fluxes.
Results. The 6.7 GHz methanol maser cloudlets are distributed over ~3500 au, and the morphology of most of them is stable although their brightness varies following the course of the total flux density on a timescale of two months. The 12.2 GHz methanol maser cloudlets cover an area an order of magnitude smaller than that of 6.7 GHz emission, and both transitions emerge from the same masing gas. The 22.2 GHz maser cloudlets lie in the central region and show a systematic increase in brightness and moderate changes in size and orientation, together with the velocity drift of the strongest cloudlet during two months of the Very Long Baseline Interferometry (VLBI) observing period. Time lag estimates imply the propagation of changes in the physical conditions of the masing region with a subluminal speed (~0.3c). A tight correlation of IR (4.6 μm) and 6.7 GHz flux densities is found, supporting the radiative pumping model. Proper motion analysis does not reveal any signs of expansion or inflow of the methanol cloudlets within ~6 mas over ~10 yr. Comparison with the 230 GHz Atacama Large Millimeter Array (ALMA) data indicates that the methanol masers are distributed in the inner part of the rotating disk, whereas the 22.2 GHz emission traces the compact inner component of the bipolar outflow or a jet structure.
Conclusions. The maser morphology in the target is remarkably stable over the course of the flare and is similar to the quiescent state, possibly due to less energetic accretion events that can repeat on a timescale of ~8 yr.
Long-term optical variability of the Be/X-ray binary GRO J2058+42
Authors: Reig P. , Tzouvanou A. , Blinov D. , Pantoulas V. 
Published: January 2023

Context. GRO J2058+42 is a transient hard X-ray pulsar that occasionally goes into outburst. The optical counterpart is a poorly studied OB-type companion.
Aims. We investigate the long-term optical variability of the Be/X-ray binary GRO J2058+42 and the possible connection with periods of enhanced X-ray activity.
Methods. We performed an optical spectroscopic and photometric analysis on data collected during about 18 yr. We also present the first optical polarimetric observations of this source.
Results. The long-term optical light curves in the BVRI bands and the evolution of the Hα equivalent width display a sinusoidal pattern with maxima and minima that repeat every ∼9.5 yr. The amplitude of this variability increases as the wavelength increases from 0.3 mag in the B band to 0.7 in the I band. The Hα equivalent width varied from about −0.3 to −15 Å. We found a significant decrease in the polarization degree during the low optical state. The intrinsic polarization degree changed by ∼1% from maximum to minimum. The optical maxima occur near periods of enhanced X-ray activity and are followed by a drop in the optical emission. Unlike many other Be/X-ray binaries, GRO J2058+42 does not display V/R variability.
Conclusions. The long-term optical variability agrees with the standard model of a Be/X-ray binary, where the circumstellar disk of the Be star grows and dissipates on timescales of 9−10 yr. We find that the dissipation of the disk started after a major X-ray outburst. However, the stability of the Hα line shape as a double-peak profile and the lack of asymmetries suggest the absence of a warped disk and argue against the presence of a highly distorted disk during major X-ray outbursts.

Le verre est-il une phase de la matière ?
Authors: Guiselin Benjamin , Berthier Ludovic 
Published: January 2023

Quoi de plus usuel que le verre ? Nous portons des lunettes, nos conversations sont transmises par fibres optiques, nos villes sont peuplées d’immeubles aux façades de verre. L’existence du verre est tangible dans notre vie quotidienne. Et pourtant… Du point de vue microscopique, la structure du verre ressemble à celle du liquide à partir duquel il a été obtenu, mais le verre est indéniablement aussi rigide qu’un matériau cristallin sans en avoir la structure ordonnée.
La définition du verre en tant que phase de la matière obtenue au travers d’une transition de phase s’accompagnant de la brisure de symétrie d’un paramètre d’ordre macroscopique reste un problème fondamental ouvert. Alors, existe-t-il une phase « verre » ?
Le verre : fragile ou ductile ?
Authors: Barthel Étienne , Deschamps Thierry , Kermouche Guillaume , Martinet Christine , Molnar Gergely , Tanguy Anne 
Published: January 2023

Les verres usuels, dits « silicatés », sont des matériaux irremplaçables car transparents, rigides et de faible cout. Mais ils ont un talon d’Achille : leur résistance mécanique, à tel point qu’ils sont l’archétype même du matériau fragile, qui reste élastique jusqu’à rupture. Cependant, à la fin des années 1940, on a observé avec étonnement que leur indentation à l’échelle du micromètre laisse une empreinte, trace incontestable d’une déformation plastique !
Réconcilier cette plasticité à l’échelle locale avec l’idée de rupture fragile reste une question ouverte, tant la description de l’écoulement plastique dans les amorphes est complexe. La conjonction de nouvelles techniques expérimentales et numériques a permis des progrès que nous décrivons ici.
Verres de chalcogénures pour le stockage de l’information
Authors: Piarristeguy Andrea , Noé Pierre , Hippert Françoise 
Published: January 2023

Certains verres de chalcogénures, alliages contenant au moins un des éléments chalcogènes (soufre, sélénium, tellure), ont suscité une attention croissante au fil des ans en raison de leur large éventail d’applications, allant de l’optique infrarouge aux mémoires non volatiles optiques et résistives. Ces dernières utilisent la capacité de certains chalcogénures à commuter rapidement et de manière réversible entre une phase amorphe fortement résistive et une phase cristalline métallique, lorsqu’on leur applique des impulsions électriques qui chauffent localement le matériau.
À partir de l’analyse du fonctionnement d’une mémoire résistive à changement de phase utilisant deux types de verres de chalcogénures, nous présentons les propriétés physiques de ces derniers ainsi que des recherches menées actuellement pour poursuivre leur optimisation.

Published: January 2023

AbstractThis observational study was conducted owing to the challenges of the positron emission tomography/magnetic resonance imaging (PET/MRI) that requires longer duration scanning of radiopharmaceutical injected patient and added MRI environment. The aim of this study was to assess radiation dose at different distances from the patient and the radiation burden to anesthesiologist and other personnel in performing PET/MRI under general anesthesia or sedation. First, the pre- and postscan whole body radiation exposure (WBE) from the patient were obtained for 45 minutes (n = 109) after injection of the radiopharmaceutical. The WBE was obtained at specific distances from brain (10, 30, and 100 cm) and abdomen (10 and 30cm) of patients undergoing F18 fluorodeoxyglucose PET/MRI brain or whole body studies. Second, WBE of the anesthesiologist and other staff working was separately measured using pocket dosimeters during the whole procedure. In brain scans, the mean absorbed dose rates (ADR) of prescan (45 minutes) and postscan (45 minutes) were 44.4 and 31.1 μSv at 10 cm, 14.9 and 9.7μSv at 30 cm, and 3.5 and 2.8 μSv at 100 cm, respectively, from surface of head. Similarly, it was 54.8 and 30.3 μSv at 10 cm, 23 and 13.6μSv at 30 cm, respectively, from surface of abdomen. In WB scans, the mean ADR was higher than the brain scans. Anesthesiologist exposure overall was found to be 4.84 µSv/patient/scan (112 patients). The anesthesiologist receives a safe mean effective dose in PET/MRI scanning. With good training and adequate planning, it is possible to decrease the radiation exposure to all the concerned personnel including anesthesiologists.
From “three doors” to “one revolving door”
Authors: Liu Yujing , Wei Xiangqing 
Published: January 2023

Abstract
The Theory of Doors (Cabré 2003) has been well established in
the academia of terminology worldwide. Many follow-up terminology studies draw on the analytical framework of this theory, namely the
linguistic, cognitive, and communicative dimensions of a terminological unit. This theory provides a comprehensive approach to the
observation of terminology, which helps with the better understanding and description of terminology in real use. With this paradigm, a
terminological unit can be investigated from any of the three dimensions, or “three doors”. However, the interrelationships among the three
dimensions have not been further elaborated, which may fail to account for the complexity of actual terminology use, in cross-lingual
settings particularly. The authors of the present study aim for an extension of the theory to cope with the research on cross-lingual and
cross-cultural terminology use by focusing on the concept of “domestic violence” in the English and Chinese languages and cultures. To
extend the Theory of Doors, the interrelatedness of the three descriptive dimensions is demonstrated based on a new
metaphorical image of “a revolving door”, and more precisely a “three-wing revolving door”.

Main text
This report describes a key comparison of mass standards APMP.M.M-K5, conducted between 19 participating members of the Asia-Pacific Metrology Programme (APMP). The APMP.M.M-K5 comparison was launched during the 13th meeting of the Technical Committee for Mass and Related Quantities APMP-TCM (2012).Two sets of stainless steel weights with five nominal mass values: 2 kg, 200 g, 50 g, 1 g, and 200 mg were used as travelling standards. These nominal values were chosen as they followed the nominal values of CCM.M-K5. The aim of the comparison is to verify the consistency of 2 kg, 200 g, 50 g, 1 g and 200 mg stainless steel mass standards among members of APMP-TCM.
The program was piloted by the National Institute of Metrology, P.R. China (NIM). All the participants have provided their support and help to successfully organize and run the comparison. The nominated 19 participants have been divided into five petals and the corresponding five sets of transfer standards have been circulated within the groups simultaneously. The pilot laboratory measured the volumes and the magnetic properties of the standards before the circulation and had reported these values to the participants. The pilot laboratory has also verified the stability of all travelling standards for more than one year. The set of five weights was circulated among all the participating laboratories in August 2015 and received back from the last participant in August 2016. The final report of this comparison is being given in this document.

The CCQM-K173 Assay of Sodium Carbonate key comparison was jointly organized by the Inorganic Analysis (IAWG) and Electrochemical Analysis and Classical Chemical Methods (EAWG) working groups of CCQM to test the abilities of the national metrology institutes (NMIs) to measure the purity or amount content of solid bases. They are important challenges for reference material producers, providers of other measurement services, such as proficiency testing schemes. Evidence of successful participation in formal, relevant international comparisons are needed to support calibration and measurement capability claims (CMCs) made by NMIs and designated institutes (DIs).
Nine NMIs participated in this key comparison CCQM-K173. National Institute of Metrology P. R. China (NIM) and Ural Research Institute for Metrology - Affiliated Branch of the D.I. Mendeleyev Institute for Metrology (VNIIM-UNIIM), Russian Federation, acted as the coordinating laboratories of the comparison.
The measurement methods used by the participants for measuring the amount content of bases expressed as sodium carbonate were coulometry and titrimetry.
In general, good overlap of results was observed, the suitability of coulometry and titrimetry for assay of high purity materials was demonstrated. The majority of results were split in two groups differing from each. This bias was however covered by the stated uncertainty estimates. Various effects have been evaluated that may cause it. However, the reason for the bias has not been identified clearly.
