Socio-Economic and Political Challenges of EU Member Countries: Grasping the Policy Direction of the European Semester
Authors: Casagrande Sara , Dallago Bruno 
Published: October 2021

AbstractThe European Semester (ES) and the country-specific recommendations (CSRs) have been introduced with the purpose to promote flexibility and adaptation to national circumstances in the governance of fiscal policies. To assess whether the ES has contributed to reconcile economic and social objectives, we measured, through the distance to frontier (DTF) score methodology, the distance of each member country from a benchmark based on EU aims and values defined in the EU treaties. Results show that EU member countries are far from the benchmark and CSRs have not prevented a progressive deterioration of stability and cohesion from an economic, political and social perspective. A content analysis of the CSRs issued from 2011 to 2018 and a comparison with the DTF scores reveal a weak connection between member countries’ performance and CSRs. Despite the social content of many CSRs, we actually observe a “commodification” of their goals. CSRs promote a society functional to flexible and competitive markets, and compatible with the requirements of fiscal discipline and sustainability. This neoliberal approach apparently played a role in the EU deterioration and makes the “socialization” of the ES a process with ambiguous implications for European citizens.

Published: October 2021

Producing high densities of molecules is a fundamental challenge for low-temperature, ion-molecule reaction studies. Traveling-wave Stark decelerators promise to deliver high density beams of cold, polar molecules but require non-trivial control of high-voltage potentials. We have overcome this experimental challenge and demonstrate continuous deceleration of ND3 from 385 to 10 m/s, while driving the decelerator electrodes with a 10 kV amplitude sinewave. In addition, we test an alternative slowing scheme, which increases the time delay between decelerated packets of ND3 and non-decelerated molecules, allowing for better energy resolution of subsequent reaction studies. We characterize this source of neutral, polar molecules suitable for energy-resolved reaction studies with trapped ions at cold translational temperatures. We also propose a combined apparatus consisting of the traveling-wave decelerator and a linear ion trap with a time-of-flight mass spectrometer and discuss to what extent it may achieve cold, energy-resolved, ion-neutral reactions.
Magnetic field sensors for detection of trapped flux in superconducting radio frequency cavities
Authors: Parajuli I. P. , Ciovati G. , Delayen J. R. 
Published: October 2021

Superconducting radio frequency (SRF) cavities are fundamental building blocks of modern particle accelerators. They operate at liquid helium temperatures (2–4 K) to achieve very high quality factors (1010–1011). Trapping of magnetic flux within the superconductor is a significant contribution to the residual RF losses, which limit the achievable quality factor. Suitable diagnostic tools are in high demand to understand the mechanisms of flux trapping in technical superconductors, and the fundamental components of such diagnostic tools are magnetic field sensors. We have studied the performance of commercially available Hall probes, anisotropic magnetoresistive sensors, and flux-gate magnetometers with respect to their sensitivity and capability to detect localized, low magnetic flux amplitudes, of the order of a few tens of magnetic flux quantum at liquid helium temperatures. Although Hall probes have the lowest magnetic field sensitivity (∼96 nV/μT at 2 K), their physical dimensions are such that they have the ability to detect the lowest number of trapped vortices among the three types of sensors. Hall probes and anisotropic magnetoresistive sensors have been selected to be used in a setup to map regions of trapped flux on the surface of a single-cell SRF cavity.
Optimizing a rapid shutdown module for pre-polarization current in surface nuclear magnetic resonance
Authors: Zhou Kun , Chen Chao , Cao Yiming , Lin Tingting 
Published: October 2021

Surface nuclear magnetic resonance (SNMR) technology is widely used for hydrological investigations. At high ambient noise levels, the use of a pre-polarization field can enhance the amplitude of the free induced decay (FID) signal. However, the spatial distribution of the pre-polarization field is inhomogeneous, and so it is vital to optimize the shutdown ramp and time for all combinations of the pre-polarization field amplitude and relative orientation. For this purpose, we designed a rapid and adiabatic shutdown circuit for pre-polarization surface nuclear magnetic resonance (PSNMR) systems. In the initial stage of the shutdown process, the magnetic field energy stored in the direct current transmitting coil is transferred to the capacitor by a semi-controlled full bridge circuit. At the end of the shutdown period, the pre-polarization current decays exponentially toward zero. The shutdown process can be controlled by adjusting the circuit parameters. The shutdown ramp and time of the designed circuit are verified through a series of simulations and experiments. As the initial voltage of the capacitor increases from 65 to 300 V, the initial amplitude of the exponential decay of the pre-polarization current increases from 15 to 48 A and the shutdown time decreases from 1.4 to 1 ms. Our design scheme provides a more reliable concept for the shutdown process in the case of multiple transmitting coils. This allows a larger gain of the FID signal to be obtained in specific PSNMR applications when pre-polarization currents with slightly different channel parameters need to be shutdown uniformly.

Context The use of buserelin, a gonadotropin-releasing hormone (GnRH) agonist, can improve semen quality. Nevertheless, the appropriate dosage, and frequency and time of application, remain to be established owing to the subsequent negative feedback on endogenous production of testosterone described so far. Aims This study aimed to propose a new buserelin application protocol for sperm improvement in Santa Inês rams. Methods Fifteen Santa Inês rams were divided into two experimental groups: the first group (n = 8) received 2.5 μg buserelin acetate; and the second group (n = 7) received saline solution. Treatments were applied for 21 days at intervals of 6 h, totalling four hormonal or saline applications per day. In all animals, macroscopic and microscopic seminal characteristics and freezability, plasma testosterone, pixels of testicular parenchyma, and biometric analysis of testicular and accessory sex glands by ultrasound were evaluated throughout the period of hormonal application and for a further 7 days. Key results Rams receiving buserelin showed a peak of testosterone after the first week (Day 7) of application, with a drop in values at Day 14, followed by negative feedback at Day 21 and return to basal concentrations at Day 28. They also showed improvement of kinetics parameters such as straight line velocity (μm/s: +buserelin 51.5 ± 1.5 > control 46.6 ± 1.6) and linearity coefficient (%: +buserelin 53.5 ± 1.8 > control 47.5 ± 1.9). Ultrasound parameters, pixels of testicular parenchyma, and freezability were not affected by treatment. Conclusions The administration of buserelin was able to improve some sperm kinetics parameters of Santa Inês rams. Implications Low doses of this GnRH analogue can be used; however, further adjustments to the hormonal protocol are needed to obtain an effective improvement in sperm quality.

Significance
Ocean emissions of dimethyl sulfide (DMS) are a major precursor for the production and growth of aerosol particles, which can act as seeds for the formation of cloud droplets in the marine atmosphere with the subsequent impacts on Earth’s climate. Global aircraft observations indicate that DMS is efficiently oxidized to hydroperoxymethyl thioformate (HPMTF), a previously unrecognized molecule, which necessitates revisiting DMS oxidation chemistry in the marine atmosphere. We show through ambient observations and global modeling that a dominant loss pathway for HPMTF is uptake into cloud droplets. This loss process short circuits gas-phase oxidation and significantly alters the dynamics of aerosol production and growth in the marine atmosphere.
Semantic network of the German preposition hinter
Authors: Kermer Franka 
Published: October 2021

Abstract
The present study sets out to construct a semantic network for the German preposition hinter (‘behind’) based on the theoretical framework of “principled polysemy”. The analysis regarding the cognitive and pragmatic aspects motivating the meaning extensions of hinter attempts to highlight the importance of varying construal patterns and vantage points as well as the role of real-world knowledge. By means of corpus data, I intend to present six senses of the preposition hinter, hinting at the polysemous nature of prepositions more generally. Furthermore, the theory of conceptual metaphor is applied to account for metaphorical extensions of hinter to more abstract domains of embodied experience.
Grammatical metonymy and construal operations
Authors: Szymańska Monika 
Published: October 2021

AbstractThis article analyses the semantic features of two constructions characterised by the specific use of morphosyntactic indicators of the category of number. The constructions are based on unusual, unobvious ways of using singular and plural forms of NP. The singular (in the first construction) and plural (in the second) forms of NP give to the constructions a metonymic character. The constructions are described as two types of metonymy, representing two different ways of construal.
Natural-scalaron inflation
Authors: Salvio Alberto 
Published: October 2021

Abstract
A pseudo Nambu-Goldstone boson (such as an axion-like particle) is a theoretically well-motivated inflaton as it features a naturally flat potential (natural inflation). This is because Goldstone's theorem protects its potential from sizable quantum corrections. Such corrections, however, generically generates an R
2 term in the action, which leads to another inflaton candidate because of the equivalence between the R
2 term and a scalar field, the scalaron, with a quasi flat potential (Starobinsky inflation). Here it is investigated a new multifield scenario in which both the scalaron and a pseudo Nambu-Goldstone boson are active (natural-scalaron inflation). For generality, also a non-minimal coupling is included, which is shown to emerge from microscopic theories. It is demonstrated that a robust inflationary attractor is present even when the masses of the two inflatons are comparable. Moreover, the presence of the scalaron allows to satisfy all observational bounds in a large region of the parameter space, unlike what happens in pure-natural inflation.
Non-Abelian vector dark matter and lepton g-2
Authors: Chowdhury Talal Ahmed , Saad Shaikh 
Published: October 2021

Abstract
The mystery of dark matter remains an unsettled problem of particle physics. On top of that, experiments show a persistent contention of the muon anomalous magnetic moment (AMM) relative to the Standard Model (SM) prediction. In this work, we consider the possibility of extending the SM with a non-Abelian gauge symmetry SU(2)
X
, under which SM leptons transform non-trivially. SM leptons receive corrections to their AMMs of right order via one-loop processes mediated by beyond SM (BSM) fermions required to cancel anomalies, and BSM gauge bosons that play the role of dark matter. We show that simultaneous explanation of the muon AMM along with reproducing correct relic abundance allows rather a narrow range of 0.5–2 TeV dark matter mass, consistent with current experimental constraints. However, a concurrent description that also includes electron AMM is challenging in this set-up.
Are fire refugia less predictable due to climate change?
Authors: Mackey Brendan , Lindenmayer David , Norman Patrick , Taylor Chris , Gould Susan 
Published: October 2021

Abstract
Fire refugia—unburnt habitat within a wildfire’s perimeter—play a key role in wildlife persistence and recovery. While studies have shown that the location of refugia is influenced by local topographic factors, growing evidence points to extreme fire weather becoming the dominant factor driving high-severity wildfires that result in the location of fire refugia being less predictable. Between September 2019 and February 2020, a series of mega-fires in eastern Australia burned largely in broadleaf forest. We assessed burned and unburned areas of forest in eastern Australia using Sentinel-2 satellite data, aggregated monthly over the fire season to calculate a fire severity layer at a 20 m pixel resolution. We found that fires burned 5.7 × 106 ha−1 of forest and woodland. The total percentage area of unburned forest within the wildfire footprint was approximately 10%. The majority (94%) of the unburnt forest and woodland patches within the fire perimeter occurred as patches <1 ha (n = 842 622 and 111 707 ha) with far fewer large unburnt patches (>100 ha) (n = 575 and 286 080 ha). Boosted regression tree analyses of the relationships between fire severity and potential explanatory variables revealed that 63%–78% of the variable importance in the models were climatic and weather-related factors. Fire weather index was the single most important variable for analyses, accounting for 40%–52% of modelled results. Our results reinforce mounting evidence that a shift is underway in the balance between deterministic and contingent factors in the occurrence of fire refugia with local topographic controls being increasingly overridden by severe fire weather conditions, and declining topographic effects as fire severity increases. Further studies are needed over a longer time frame, inclusive of prior forest management impacts, to confirm that the ability to predict fire refugia is permanently declining.

Abstract
During the spring of 2020, the coronavirus disease 2019 (COVID-19) epidemic caused an unprecedented demand for intensive-care resources in the Lombardy region of Italy. Using data on 43,538 hospitalized patients admitted between February 21 and July 12, 2020, we evaluated variations in intensive care unit (ICU) admissions and mortality over the course of 3 periods: the early phase of the pandemic (February 21–March 13), the period of highest pressure on the health-care system (March 14–April 25, when numbers of COVID-19 patients exceeded prepandemic ICU bed capacity), and the declining phase (April 26–July 12). Compared with the early phase, patients aged 70 years or more were less often admitted to an ICU during the period of highest pressure on the health-care system (odds ratio (OR) = 0.47, 95% confidence interval (CI): 0.41, 0.54), with longer ICU delays (incidence rate ratio = 1.82, 95% CI: 1.52, 2.18) and lower chances of dying in the ICU (OR = 0.47, 95% CI: 0.34, 0.64). Patients under 56 years of age had more limited changes in the probability of (OR = 0.65, 95% CI: 0.56, 0.76) and delay to (incidence rate ratio = 1.16, 95% CI: 0.95, 1.42) ICU admission and increased mortality (OR = 1.43, 95% CI: 1.00, 2.07). In the declining phase, all quantities decreased for all age groups. These patterns may suggest that limited health-care resources during the peak phase of the epidemic in Lombardy forced a shift in ICU admission criteria to prioritize patients with higher chances of survival.
The Anticonvulsant Lamotrigine Reduces Bout-Like Alcohol Drinking in Rats

Published: October 2021

Abstract
We used an optical lickometer system to study drinking microstructure and effect of lamotrigine in voluntary alcohol-drinking rats. We showed that, similar to humans, animals differ by their drinking microstructure where some consume alcohol exclusively in a bout-like patterns. The study suggests that anticonvulsants, such as lamotrigine, may be one treatment strategy specifically affecting this type of drinking.
Transgenerational effects of temperature fluctuations inArabidopsis thaliana
Authors: Deng Ying , Bossdorf Oliver , Scheepens J F 
Published: October 2021

AbstractPlant stress responses can extend into the following generations, a phenomenon called transgenerational effects. Heat stress, in particular, is known to affect plant offspring, but we do not know to what extent these effects depend on the temporal patterns of the stress, and whether transgenerational responses are adaptive and genetically variable within species. To address these questions, we carried out a two-generation experiment with nine Arabidopsis thaliana genotypes. We subjected the plants to heat stress regimes that varied in timing and frequency, but not in mean temperature, and we then grew the offspring of these plants under controlled conditions as well as under renewed heat stress. The stress treatments significantly carried over to the offspring generation, with timing having stronger effects on plant phenotypes than stress frequency. However, there was no evidence that transgenerational effects were adaptive. The magnitudes of transgenerational effects differed substantially among genotypes, and for some traits the strength of plant responses was significantly associated with the climatic variability at the sites of origin. In summary, timing of heat stress not only directly affects plants, but it can also cause transgenerational effects on offspring phenotypes. Genetic variation in transgenerational effects, as well as correlations between transgenerational effects and climatic variability, indicates that transgenerational effects can evolve, and have probably already done so in the past.

Abstract
Although some individuals with at-risk mental states (ARMS) develop overt psychosis, surrogate markers which can reliably predict a future onset of psychosis are not well established. The dorsal lateral prefrontal cortex (DLPFC) is thought to be involved in psychotic disorders such as schizophrenia. In this study, 73 ARMS patients and 74 healthy controls underwent 1.5-T 3D magnetic resonance imaging scans at three sites. Using labeled cortical distance mapping, cortical thickness, gray matter (GM) volume, and surface area of DLPFC were estimated. These measures were compared across the diagnostic groups. We also evaluated cognitive function among 36 ARMS subjects to clarify the relationships between the DLPFC morphology and cognitive performance. The GM volume of the right DLPFC was significantly reduced in ARMS subjects who later developed frank psychosis (ARMS-P) relative to those who did not (P = 0.042). There was a positive relationship between the right DLPFC volume and the duration prior to the onset of frank psychosis in ARMS-P subjects (r = 0.58, P = 0.018). Our data may suggest that GM reduction of the DLPFC might be a potential marker of future onset of psychosis in individuals with ARMS.
Risk stratification in cardiomyopathies (dilated, hypertrophic, and arrhythmogenic cardiomyopathy) by cardiac magnetic resonance imaging
Authors: Guglielmo Marco , Pontone Gianluca 
Published: October 2021

Abstract
Cardiac magnetic resonance imaging (CMR) is a non-invasive, multiplanar, and high spatial resolution imaging technique, which represents the current gold standard for the evaluation of biventricular volumes and function. Furthermore, unlike other methods, it has the great advantage of characterizing the myocardial tissue by identifying the presence of alterations, such as oedema and focal and diffuse fibrosis. In particular, the late gadolinium enhancement technique makes it possible to identify areas of focal fibrosis that often constitute the substrate for the triggering of threatening ventricular arrhythmias at the basis of sudden cardiac death. For this reason, the use of CMR in the study of cardiomyopathies has become of primary importance, both for the differential diagnosis and for patient risk stratification. In this brief review, the ability of CMR in prognostic stratification of patients with dilated, hypertrophic, and arrhythmogenic cardiomyopathy will be analysed. In particular, the role of CMR in the prediction of arrhythmic risk and in the decision-making process for the implantation of a cardiac defibrillator will be examined.
