FT‐LVIO: Fully Tightly coupled LiDAR‐Visual‐Inertial odometry
Authors: Zhang Zhuo , Yao Zheng , Lu Mingquan 
Published: January 2023

AbstractIn this paper, we propose a fully tightly‐coupled multi‐sensor fusion framework termed FT‐LVIO, that fuses measurements from a light detection and ranging (LiDAR), a monocular camera and an inertial measurement unit (IMU) simultaneously to achieve robust and accurate state estimation in real time. FT‐LVIO is built atop the framework of an error‐state‐iterated Kalman filter. To take full advantage of the complimentary characteristics of individual sensors, LiDAR point clouds are undistorted by IMU prediction to the nearest camera exposure time and the filter is updated with measurements from all sensors. In addition, an efficient sampling method for the LiDAR point‐to‐plane measurements is proposed, which can help select the measurements providing sufficient constraints to the pose estimation and facilitate a low‐drift odometry. Extensive experiments are performed on both the public NTU dataset and the private handheld dataset, and the results show that the proposed FT‐LVIO outperforms the state‐of‐the‐art LiDAR‐inertial, visual‐inertial and LiDAR‐visual‐inertial methods in both accuracy and robustness. Furthermore, FT‐LVIO can survive in the challenging staircase environment.
Texture of average solar photospheric flows and the donut-like pattern

Published: January 2023

Context. Detailed knowledge of surface dynamics is one of the key points in understanding magnetic solar activity. The motions of the solar surface, to which we have direct access via the observations, tell us about the interaction between the emerging magnetic field and the turbulent fields.
Aims. The flows computed with the coherent structure tracking (CST) technique on the whole surface of the Sun allow for the texture of the velocity modulus to be analyzed and for one to locate the largest horizontal flows and determine their organization.
Methods. The velocity modulus maps show structures more or less circular and closed which are visible at all latitudes; here they are referred to as donuts. They reflect the most active convective cells associated with supergranulation. These annular flows are not necessarily joined as would seem to indicate the divergence maps.
Results. The donuts have identical properties (amplitude, shape, inclination, etc. ) regardless of their position on the Sun. The average donuts computed from all the donuts shows an asymmetry east-west of the amplitude which is related to previous works on the wave-like properties of supergranulation. A kinematic simulation of the donuts’ outflow applied to passive scalar (corks) indicates the preponderant action of the selected donuts which are, from our analysis, one of the major actors for the magnetic field diffusion on the quiet Sun.
Conclusions. The absence of donuts in the magnetized areas (plages) indicates the action of the magnetic field on the strongest supergranular flows and thus modifies the diffusion of the magnetic field in that location. The detection of the donuts is a way to locate – in the quiet Sun – the vortex and the link with the jet, blinkers, coronal bright points (campfires), or other physical structures. Likewise, the study of the influence of donuts on the evolution of active events, such as the destruction of sunspots, filament eruptions, and their influences on upper layers via spicules and jets, could be done more efficiently via the detection of that structures.

Aims. We aim to better constrain the atmospheric properties of the directly imaged exoplanet 51 Eri b using a retrieval approach with data of higher signal-to-noise ratio (S/N) than previously reported. In this context, we also compare the results from an atmospheric retrieval to using a self-consistent model to fit atmospheric parameters.
Methods. We applied the radiative transfer code petitRADTRANS to our near-infrared SPHERE observations of 51 Eri b in order to retrieve its atmospheric parameters. Additionally, we attempted to reproduce previous results with the retrieval approach and compared the results to self-consistent models using the best-fit parameters from the retrieval as priors.
Results. We present a higher S/N YH spectrum of the planet and revised K1K2 photometry (MK1 = 15.11 ± 0.04 mag, MK2 = 17.11 ± 0.38 mag). The best-fit parameters obtained using an atmospheric retrieval differ from previous results using self-consistent models. In general, we find that our solutions tend towards cloud-free atmospheres (e.g. log τclouds = −5.20 ± 1.44). For our 'nominal' model with new data, we find a lower metallicity ([Fe/H] = 0.26 ± 0.30 dex) and C/O ratio (0.38 ± 0.09), and a slightly higher effective temperature (Teff = 807 ± 45 K) than previous studies. The surface gravity (log g = 4.05 ± 0.37) is in agreement with the reported values in the literature within uncertainties. We estimate the mass of the planet to be between 2 and 4 MJup. When comparing with self-consistent models, we encounter a known correlation between the presence of clouds and the shape of the P–T profiles.
Conclusions. Our findings support the idea that results from atmospheric retrievals should not be discussed in isolation, but rather along with self-consistent temperature structures obtained using the best-fit parameters of the retrieval. This, along with observations at longer wavelengths, might help to better characterise the atmospheres and determine their degree of cloudiness.

Abstract
Introduction Preterm delivery (gestational age < 34 w) is a relative contraindication to vacuum extraction. Current data do not differentiate clearly between preterm delivery and
low birthweight. We aimed to evaluate the impact of non-metal vacuum cup extraction on neonatal head injuries related to birth trauma in newborns with low birthweights (< 2500 g).
Materials and Methods A retrospective cohort of 3377 singleton pregnancies delivered by vacuum extraction from 2014 to 2019. All were gestational age ≥ 34 w. We compared 206 (6.1%)
neonates with low birthweights < 2500 g to 3171 (93.9%) neonates with higher birthweights, divided into 3 subgroups (2500–2999 g, 3000–3499 g, and ≥ 3500 g). A primary composite outcome
of neonatal head injuries related to birth trauma was defined.
Results The lowest rates of subgaleal hematoma occurred in neonates < 2500 g (0.5%); the rate increased with every additional 500 g of neonatal birthweight (3.5%, 4.4% and 8.0% in
the 2500–2999 g, 3000–3499 g, and ≥ 3500 g groups, respectively; p = 0.001). Fewer cephalohematomas occurred in low birthweight neonates (0.5% in < 2500 g), although the percentage
increased with every additional 500 g of birthweight (2.6%, 3.3% and 3.7% in the 2500–2999 g, 3000–3499 g, and ≥ 3500 g groups, respectively, p = 0.020). Logistic regression found increasing
birthweight to be a significant risk factor for head injuries during vacuum extraction, with adjusted odds ratios of 8.12, 10.88, and 13.5 for 2500–2999 g, 3000–3499 g, and ≥ 3500 g,
respectively (p = 0.016). NICU hospitalization rates were highest for neonates weighing < 2500 g (10.2%) compared to the other groups (3.1%, 1.7% and 3.3% in 2500–2999 g, 3000–3499 g,
≥ 3500 respectively, p < 0.001).
Conclusions Vacuum extraction of neonates weighing < 2500 g at 34 w and beyond seems to be a safe mode of delivery when indicated, with lower rates of head injury related to birth
trauma, compared to neonates with higher birthweights.

Abstract
Introduction Meningiomas—the most common extra-axial tumors—are benign, slow-growing dural-based lesions that can involve multiple cranial fossae and can progress insidiously for years until coming to clinical attention secondary to compression of adjacent neurovascular structures. For complex, multicompartmental lesions, multistaged surgeries have been increasingly shown to enhance maximal safe resection while minimizing adverse sequela. Here, we systematically review the extant literature to highlight the merits of staged resection.
Methods PubMed, Scopus, and Web of Science databases were queried to identify articles reporting resections of intracranial meningiomas using a multistaged approach, and articles were screened for possible inclusion in a systematic process performed by two authors.
Results Of 118 identified studies, 36 describing 169 patients (mean age 42.6 ± 21.3 years) met inclusion/exclusion criteria. Petroclival lesions comprised 57% of cases, with the most common indications for a multistaged approach being large size, close approximation of critical neurovascular structures, minimization of brain retraction, identification and ligation of deep vessels feeding the tumor, and resection of residual tumor found on postoperative imaging. Most second-stage surgeries occurred within 3 months of the index surgery. Few complications were reported and multistaged resections appeared to be well tolerated overall.
Conclusions Current literature suggests multistaged approaches for meningioma resection are well-tolerated. However, there is insufficient comparative evidence to draw definitive conclusions about its advantages over an unstaged approach. There are similarly insufficient data to generate an evidence-based decision-making framework for when a staged approach should be employed. This highlights the need for collaborative efforts among skull base surgeons to establish an evidentiary to support the use of staged approaches and to outline those indications that merit such an approach.
New, Scalable Process for the Preparation of 5-Acetyl-1H-pyrazole-3-carboxylic Acid, a Key Intermediate of Darolutamide

Published: January 2023

AbstractA new, efficient process for the synthesis of 5-acetyl-1H-pyrazole-3-carboxylic acid, a versatile building block and the key intermediate of darolutamide, using diethyl pyrazole-3,5-dicarboxylate as the starting material is described. Contrary to the synthetic routes known from the literature, this procedure does not employ explosive diazo reagents, moreover it is simple and safe, thereby suitable for scale-up.
Circulating Fatty Acid-binding Protein 4 Response to Acute Aerobic
Exercise in Healthy Men
Authors: Numao Shigeharu , Uchida Ryota , Kurosaki Takashi , Nakagaichi Masaki 
Published: January 2023

AbstractThis study aimed to investigate the association between changes in FABP4
concentration and hormone and metabolite levels during and after acute low- and
moderate-intensity aerobic exercise in healthy men. Eleven healthy men
(24.4±1.4 years) were administered three trials in random order: 1)
low-intensity aerobic exercise trial (LE trial; acute exercise at 40%
peak oxygen uptake [Vo2peak]+bed rest), 2) moderate-intensity
aerobic exercise trial (ME trial: acute exercise at
60%Vo2peak+bed rest), and 3) bed rest (Con trial).
Expired gas and venous blood samples were collected at baseline, and
immediately, 30 and 60 min after exercise, and substrate oxidation and
hormone, metabolite, and FABP4 concentrations were measured. FABP4 concentration
did not increase during aerobic exercise in LE and ME trials (p>0.05).
However, FABP4 concentration significantly increased after the acute aerobic
exercise in both the LE and ME trials (p≤0.003). Increased FABP4
concentration after acute exercise was not correlated with adrenaline,
noradrenaline, other hormone, and metabolite concentration changes. These
findings suggest that FABP4 concentration increases after acute aerobic exercise
independently of exercise intensity. Furthermore, increased FABP4 concentration
after acute aerobic exercise may not be involved in the magnitude of adrenaline,
noradrenaline, and lipolytic response.
Invented corporate heritage brands
Authors: Brunninge Olof 
Published: January 2023

AbstractThis article examines the phenomenon of invented corporate heritage brands, i.e. heritage that is made up, exaggerated or far-fetched, to an extent that stakeholders may challenge its accuracy. Along six empirical cases, three dimensions characterizing invented heritage are identified, namely facticity, historical connectedness/disconnectedness, and temporal expansion/contraction. Companies draw on three different strategies to build invented corporate heritage brands: The appropriation strategy builds a heritage brand by leveraging the past of organizations that are forerunners of the present firm The forgetting strategy omits or tones down parts of the past that are deemed as not being useful for the brand. Eventually, the fantasizing strategy constructs a brand based on a purely invented past. Overall, the article provides evidence of the high degree of pragmatic flexibility (Burghausen and Balmer in Corporate Communications: an International Journal 19: 384–402, 2014a) inherent in corporate heritage. It also demonstrates how young brands can be infused with heritage, by appropriating the past of historical forerunners that are meaningfully connected to the brand.
Visible active narrow/narrow band gap CuO/Cu2SnS3 nanoheterostructures as efficient nanophotocatalysts
Authors: Arafa Mona , Abdelmonem Yasser , Madkour Metwally 
Published: January 2023

Binary metal oxide/ternary metal sulphide based nanoheterostructures, such as CuO/Cu2SnS3, were prepared via a modified hydrothermal route. The prepared nanoheterostructures were characterized using scanning electron microscopy, x-ray powder diffractometer, XPS, ultraviolet–visible spectroscopy, isoelectric point, and Brunauer-Emmett-Teller techniques. The XPS results revealed the successful incorporation of Cu+/Cu2+ with different ratios. The prepared heterostructures were tested as solar active photocatalysts for Methylene Blue (MB) photodegradation. The CuO/Cu2SnS3 (20% Cu2SnS3/80% CuO) photocatalytic results exhibited a high photodegradation efficiency (90%) after 60 min. In addition, the photonic efficiency values (ζ) were calculated to be 15.9%, 44%, and 61.4% for CuO, Cu2SnS3, and CuO/Cu2SnS3 nanoheterostructures, respectively. In addition, the reactive oxidative species were detected by the trapping experiments to get a clear insight about the photocatalytic reactivity factors. Total organic carbon (TOC) was conducted to confirm the safe photodegradation of MB dye without the formation of colorless hazardous (95.5% TOC removal). Based on the electronic band structure, the mechanism of photodegradation was investigated. The currently investigated heterostructure system is narrow/narrow bandgap, which fulfills the two contradictory conditions in terms of high solar photocatalytic activity and overcomes the rapid recombination process.
Did the coronavirus vaccination program in a rural and regional area work? Health outcomes of the vaccination program in Wide Bay
Authors: Kitchener Scott 
Published: January 2023

The objective of this case study is to evaluate the effectiveness of the Wide Bay region coronavirus vaccination program in preventing hospitalisation for coronavirus disease 2019 (COVID-19). Population vaccination data and the vaccination status of patients hospitalised with confirmed COVID-19 have been used to evaluate preventable hospitalisations and risk reduction during and after a 2 month period following the outbreak of COVID-19 in Wide Bay after removal of public health measures in Queensland in December 2021. Wide Bay is a rural region of Queensland including K’Gari (formerly Fraser Island) to the east, the North Burnett farming region in the west and extending from the Fraser Coast to the Discovery Coast. Two local regional hospitals received and managed hospitalised COVID-19 patients. The region had, at this time, 171 365 people 20 years and older eligible for coronavirus vaccination. The risk reduction for hospitalisation of those receiving fewer than two vaccinations, two vaccinations and three vaccinations was calculated to determine the vaccination program effectiveness. The program achieved 90% effectiveness for people with two or more vaccinations (those with two vaccinations and those receiving boosters of third or more vaccination), and 97% effectiveness for those having received three vaccinations, in preventing hospitalisation for COVID-19 during the period. This translated into a significant risk reduction for hospitalisation for those receiving two or more vaccinations, preserving capacity to enable the health service to manage all cases locally.

The myophage possesses a contractile tail that penetrates its host cell envelope. Except for investigations on the bacteriophage T4 with a rather complicated structure, the assembly pattern and tail contraction mechanism of myophage remain largely unknown. Here, we present the fine structure of a freshwater
Myoviridae
cyanophage Pam3, which has an icosahedral capsid of ~680 Å in diameter, connected via a three-section neck to an 840-Å-long contractile tail, ending with a three-module baseplate composed of only six protein components. This simplified baseplate consists of a central hub-spike surrounded by six wedge heterotriplexes, to which twelve tail fibers are covalently attached via disulfide bonds in alternating upward and downward configurations. In vitro reduction assays revealed a putative redox-dependent mechanism of baseplate assembly and tail sheath contraction. These findings establish a minimal myophage that might become a user-friendly chassis phage in synthetic biology.
Contrast marking variation in Romance and Germanic languages
Authors: Andorno Cecilia , Benazzo Sandra , Dimroth Christine 
Published: January 2023

Abstract
In research on information structure and discourse cohesion, contrast has been defined in different ways,
depending on the pragmatic/semantic relation established between the propositions involved in the contrast, on the text types and
on other discourse conditions. As a whole, despite – or possibly because of – its vagueness, contrast has proved to be a useful
heuristic tool for characterizing discourse cohesion phenomena. This paper focuses on results from our research concerning
cohesion phenomena in elicited discourse in Romance (Italian, French) and Germanic (German, Dutch) languages and aims to offer a
more precise characterization of contrast against several variation parameters. We take into consideration earlier work on three
tasks (Finite Story, Polarity-Switch Dialogues, Map Task) and add a new one
(Spot the Difference). The comparison between the results allows us to disentangle the following variables:
information units involved in the contrast relation; discourse conditions (monologue vs. dialogue); speakers’ access to
information (shared vs. non-shared); effect of contrast on information in the common ground (alternative maintained vs. rejected).
The aim is to achieve a more fine-grained definition of contrast relations, which allows us to identify and characterize the
divergent behavior of Romance and Germanic languages, and to relate intra- and crosslinguistic differences revealed by speakers’
preferences in speech with structural specificities of the two language groups.
Abstraction in storytelling
Authors: Pihlaja Stephen 
Published: January 2023

Abstract
Discussions of storytelling and narrative have encompassed abstraction in different ways including master
narratives (Bamberg, 1997) and storylines (Harré
& van Lagenhove, 1998). These discussions, however, have often viewed storytelling and abstraction as a binary
distinction, rather than a spectrum where speakers move between different levels of abstraction when recounting experiences. This
article argues for a nuanced approach to abstraction in storytelling that considers how specific details of stories – namely,
actors, actions, contexts, and time – are excluded or abstracted in the recounting of experience, with a link between increased
abstraction and implied moral judgement. The article first outlines the theoretical basis for this argument, and then shows
specific examples of abstraction taken from stories about religious experience. Finally, the productive implications of a nuanced
view of abstraction are outlined, including for narrative and discourse analysis, for understanding of storytelling and cognition,
and for critical analysis of racist language.
Grain boundary and grain interior strengthening in nano-micron grain sized Cu-1wt.%Al2O3 composite

Published: January 2023

A bulk Cu-1 wt%Al2O3 composite was synthesised to 97–99% theoretical density by mechanical alloying and spark plasma sintering to get varying grain sizes in the range 70 nm–2 µm. Tensile tests were done at room temperature, and the substructure evolution was examined as a function of the grain size and strain. The flow property revealed bilinear Hall–Petch relationship with a transition at 0.55 µm grain size. The stress–strain curves were found to follow the Hollomon-type relationship exhibiting an increase in strength coefficient and a decrease in strain hardening exponent with decreasing grain size. The variations in flow stress with grain size and strain delineate equivalent effects. The inter-dependence between the grain size and strain is explained by the substructure evolution and its contribution to the partitioning of work hardening between the grain interior and grain boundaries.
