Inferring the age and environmental characteristics of fossil sites using citizen science

Not all fossil sites preserve microfossils that can be extracted using acid digestion, which may leave knowledge gaps regarding a site’s age or environmental characteristics. Here we report on a citizen science approach that was developed to identify microfossils in situ on the surface of sedimentary rocks. Samples were collected from McGraths Flat, a recently discovered Miocene rainforest lake deposit located in central New South Wales, Australia. Composed entirely of iron-oxyhydroxide, McGraths Flat rocks cannot be processed using typical microfossil extraction protocols e.g., acid digestion. Instead, scanning electron microscopy (SEM) was used to automatically acquire 25,200 high-resolution images from the surface of three McGraths Flat samples, covering a total area of 1.85 cm2. The images were published on the citizen science portal DigiVol, through which 271 citizen scientists helped to identify 300 pollen and spores. The microfossil information gained in this study is biostratigraphically relevant and can be used to constrain the environmental characteristics of McGraths Flat. Our findings suggest that automated image acquisition coupled with an evaluation by citizen scientists is an effective method of determining the age and environmental characteristics of fossiliferous rocks that cannot be investigated using traditional methods such as acid digestion.
Outcome of premarital genetic counseling for couples at risk of hemoglobinopathies in Kingdom of Bahrain

Objectives Hemoglobinopathies are the commonest inherited blood disorders and form a serious burden worldwide, affecting communities, patient quality of life and healthcare resources. The Kingdom of Bahrain has issued a law obligating couples to undergo premarital screening to detect those at risk of having children affected with these disorders. The aim of this study was to analyze the marital decisions of couples at risk for hemoglobinopathies and follow up the outcomes. Methods A retrospective study was conducted on couples at risk for hemoglobinopathies identified during the premarital screening program at local health centers in the Kingdom of Bahrain and referred to the genetics department in the Salmaniya Medical Complex for genetic counselling in 2018–2020. Results A total of 189 couples were found to be at risk for hemoglobinopathies, of whom 159 completed the survey. Of these, 107 (67%) decided to proceed with their marriage and 26 couples achieved pregnancy. Out of 24 at-risk pregnancies with known outcome, 83.3% were spontaneous whereas only 16.7% underwent in-vitro fertilization (IVF) with preimplantation genetic diagnosis (PGD). Eight out of 20 infants born to couples after spontaneous conception were affected. A positive attitude toward IVF with PGD was held by 60% of at-risk couples. Conclusions Despite undergoing premarital screening and genetic counselling, a large percentage of at-risk couples proceeded with their marriage. Most of them justified their decision due to the availability of advanced methods that aid in the prevention of having an affected child. However, the cost of such intervention was a major barrier for the majority of couples.
Effectiveness of Volbella (VYC-15L) for Infraorbital Hollowing: Patient-Reported Outcomes From a Prospective, Multicenter, Single-Blind, Randomized, Controlled Study

Abstract Background Infraorbital hollowing can be addressed with hyaluronic acid soft tissue fillers. A prospective, multicenter, evaluator-blinded, randomized, controlled study (NCT03418545) demonstrated the safety and effectiveness of Juvéderm Volbella XC (VYC-15L, Allergan Aesthetics, an AbbVie company, Irvine, CA) in adults seeking correction for infraorbital hollows. Objective The objective of the current analysis was to examine patient-reported outcomes from the clinical study. Methods Participants were randomly assigned 3:1 to the VYC-15L treatment group or the no-treatment control group. Outcome measurements included: evaluating investigator (EI)- and participant-assessed Global Aesthetic Improvement Scale (GAIS) scores, as well as participant responses to the FACE-Q Appraisal of Lower Eyelids, questions on treatment satisfaction, the extent to which patients were bothered by dark circles under their eyes, and willingness to recommend treatment to a friend. Results The modified intent-to-treat population included 135 participants (median age, 47 years; 91.9% female). At Month 3, the majority of VYC-15L-treated participants showed improvements in the EI- and participant-assessed GAIS. The mean change from baseline to Month 3 score (32.7% increase) showed statistically significant improvement (mean [standard deviation], 17.8 [19.8], P < .0001). At Months 3 and 12 posttreatment, most VYC-15L-treated participants reported feeling satisfied with treatment and not feeling moderately or very bothered by dark circles under their eyes, and would recommend treatment to a friend. Conclusions The current analysis demonstrated the effectiveness of VYC-15L treatment to reduce infraorbital hollowing and to improve overall satisfaction based on validated patient-reported outcomes. Participant-assessed improvements aligned with EI-assessed outcomes and lasted for 1 year. Level of Evidence: 2
Dynamic Structural Equation Modeling of the Relationship Among Daily Workplace Incivility, Daily Emotional Exhaustion, Self-Reported Health and Psychological Capital

This was a daily diary study using intensive longitudinal methods to evaluate the dynamic structure of relationships among employees’ self-reported health, psychological capital, daily workplace incivility, and daily emotional exhaustion. We recruited 200 participants working in health and fitness clubs for experience sampling and had them file the same questionnaires for 10 consecutive working days. A total of 179 participants (men = 57, 31.85%; women = 122, 68.15%) completed the questionnaires, with a response rate of 89.5%, leading to 1790 data points at the within-person level. We used a multilevel location-scale model of dynamic structural equation modeling (DSEM) for data analysis. We ran the model in Mplus software (version 8.4) and found an autoregressive ‘carry over’ relationship between the previous day’s emotional exhaustion changes on current emotional exhaustion changes ( γ 10 = 0.067, CI = [0.003, 0.132]). Daily workplace incivility significantly and positively predicted daily emotional exhaustion at the within-person level ( γ 20 = 0.953, CI = [0.465, 1.489]). Self-reported health was negatively associated with a person’s mean ratings of daily emotional exhaustion ( γ 20 = −0.256, CI = [0.465, 1.489]) and moderated the strength of the workplace incivility effect on emotional exhaustion ( γ 21 = −0.201, CI = [−0.292, −0.121]). Finally, psychological capital was negatively related to a person’s mean ratings of daily emotional exhaustion ( γ 02 = −0.240, CI = [−0.377, −0.102]).
The Application of New Approach Methodologies in Respiratory Disease Research: Their Role in Improving Translational Medicine from Bench to Bedside

The SARS-CoV-2 outbreak focused global attention on the shortcomings of the drug discovery process. It led to its acceleration in several areas, particularly in the processes associated with the development and approval of COVID-19 vaccines. This situation contrasts with the low approval rates of new drugs for respiratory system diseases (e.g. asthma, chronic obstructive pulmonary disease, cancer, tuberculosis), which are leading causes of morbidity and mortality worldwide. In this context, innovation in respiratory system drug discovery is surely needed, and it is most likely to succeed through the use of preclinical models that are cost-effective, high-throughput and generate predictive human-relevant outcomes. Here, we highlight several non-animal new approach methodologies (NAMs) and their applications in respiratory research. We describe their potential uses for efficacy and toxicity assessments, to optimise the drug development process and reduce the high failure rates in clinical trials.
Manual therapy for non-radicular cervical spine related impairments: establishing a ‘Trustworthy’ living systematic review and meta-analysis

ABSTRACT Objectives To establish a ‘trustworthy’ living systematic review (SR) with a meta-analysis of manual therapy for treating non-radicular cervical impairments. Design SR with meta-analysis Literature Search Articles published between January 2010 and September 2022 were included from: Cochrane Central Register of Controlled Trials (CENTRAL); CINAHL; MEDLINE; PubMed; PEDro, and ProQuest Nursing and Allied Health. Methods This SR included English-language randomized clinical trials (RCTs) of manual therapy involving adults used to treat non-radicular cervical impairments. The primary outcomes were pain and region-specific outcome measures. Cervicogenic headaches and whiplash were excluded to improve homogeneity. Two reviewers independently assessed RCTs. The prospective plan was to synthesize results with high confidence in estimated effects using GRADE. Results Thirty-five RCTs were screened for registration status. Twenty-eight were not registered or registered prospectively. In 5 studies, the discussion and conclusion did not match the registry, or this could not be determined. One study did not meet the external validity criterion, and another was rated as having a high risk of bias. One study met the inclusion and exclusion criteria, so practice recommendations could not be made. The remaining study did not identify any clinically meaningful group differences. Discussion Only one prospectively registered RCT met this SR’s strict, high-quality standards. The single identified paper provides initial high-quality evidence on this topic. Conclusion This SR establishes a foundation of trustworthiness and can be used to generate research agendas to determine the potential clinical utility of manual therapy directed at the cervical spine for non-radicular cervical complaints.
Superconducting cavity material for the European XFEL

Analysis of the strategy for superconducting cavity material procurement and quality management is done on the basis of the experience with the cavity production for the European x-ray free electron laser (EXFEL) facility. An adjustment of the material specification to EXFEL requirements, procurement of material, quality control (QC), documentation, and shipment to cavity producers have been worked out and carried out by DESY. A multistep process of qualification of the material suppliers included detailed material testing, single- and nine-cell cavity fabrication, and cryogenic radiofrequency tests. Production of about 25 000 semi-finished parts of high purity niobium and niobium-titanium alloy in a period of three years has been divided finally between companies Heraeus, Tokyo Denkai, Ningxia OTIC, and PLANSEE. Consideration of large-grain (LG) material as a possible option for the EXFEL has resulted in the production of one cryogenic module consisting of seven (out of eight) LG cavities. LG materials fulfilled the EXFEL requirements and showed even 25% to 30% higher unloaded quality factor. A possible shortage of the required quantity of LG material on the market led, however, to the choice of conventional fine-grain (FG) material. Eddy-current scanning (ECS) has been applied as an additional QC tool for the niobium sheets and contributed significantly to the material qualification and sorting. Two percent of the sheets have been rejected, which potentially could affect up to one-third of the cavities. The main imperfections and defects in the rejected sheets have been analyzed. Samples containing foreign material inclusions have been extracted from the sheets and electrochemically polished. Some inclusions remained even after 150 μm surface layer removal. Indications of foreign material inclusions have been found in the industrially fabricated and treated cavities and a deeper analysis of the defects has been performed.
Research progress on the role of ET‐1 in diabetic kidney disease

Diabetic kidney disease (DKD) is one of the common complications of diabetes mellitus, which usually progresses to end‐stage renal disease and causes great damage to the health of patients. Endothelin‐1 (ET‐1), a molecule closely associated with the progression of DKD, has increased expression in response to high glucose stimulation and is involved in hemodynamic changes, inflammation, glomerular and tubular dysfunction in the kidney, causing an increase in proteinuria and a decrease in glomerular filtration function, ultimately leading to glomerulosclerosis and renal failure. This paper aims to review the molecular level changes, regulatory mechanisms, and mechanisms of action of ET‐1 under DKD, clinical trials of ET‐1 receptor antagonists in recent years and current problems, to provide basic information and new research directions and ideas for the treatment of DKD and ET‐1‐related research.
The Hilbert Polynomial of Quandles and Colorings of Random Links

Given a finite quandle $Q$, we study the average number of $Q$-colorings of the closure of a random braid in $B_n$ as $n$ varies. In particular we show that this number coincides with some polynomial $P_Q\in \mathbb{Q}[x]$ for $n\gg 0$. The degree of this polynomial is readily computed in terms of $Q$ as a quandle and these invariants are computed for all quandles with $|Q|\le 4$. Additionally we show that the methods in this paper allow to improve on the stability results of arXiv:0912.0325 from"periodic stability"to"stability".
Bypass, Augment, or Integrate

This 3-year qualitative study examined how 26 teachers in four U.S. secondary schools addressed the literacy demands of curriculum materials based on standards from the National Council of Teachers of Mathematics. It was grounded in sociocultural perspectives that encourage study of language in local contexts, including classrooms, communities, and disciplines. The research question asked, “How do secondary mathematics teachers in a teacher–researcher collaboration understand and address the literacy demands of standards-based curriculum materials? ” An interdisciplinary team of literacy and mathematics education researchers and graduate students worked with teachers to examine required curriculum materials, plan lessons, and share resources, while collecting qualitative data to capture teachers’ understandings and actions. Findings indicated that teachers responded in three ways to the materials’ literacy demands: (a) they used the materials selectively to bypass or reduce the literacy demands, (b) they augmented use of the materials with literacy support, or (c) they integrated use of the materials into long-term frameworks to develop mathematics and literacy learning simultaneously. The study suggests the value of using insights from mathematics and literacy to inform mathematics curriculum design and reminds us to take teachers’ perspectives toward such materials seriously, particularly when they collaborate to address issues about the materials’ use in their own school contexts.
Early orthodontic treatment need in paediatric age: a prospective observational study in Italian school-children.

AIM This study evaluates the prevalence of Interceptive Orthodontic Treatment Need (IOTN) in Italian school-children. METHODS A prospective observational study was conducted to assess the prevalence of IOTN in patients undergoing a first visit at the Santa Chiara Hospital Paediatric Dentistry Unit in Pisa, Italy. Two thousand, one hundred ninetynine subjects met the inclusion criteria and were enrolled in the study; data on age, gender and concomitant systemic pathologies were collected from medical records. All participants were examined for individual IOTN: the presence of anterior and/or unilateral/bilateral crossbite with or without midline deviation, bad habits (finger, sucking habits, mouth breathing, and tongue thrust), overjet > 3 mm, lack of space for 1.2 and 2.2 eruption were investigated. The presence of one of the above mentioned parameters was considered positive for IOTN. Chi-square test was used to evaluate any statistically significant difference (p < 0.05). CONCLUSION The study confirms the presence of a significant percentage of paediatric patients who need IOTN; early treatment is highly recommended to reduce malocclusion outcomes in the adult population.
Stable blowup for focusing semilinear wave equations in all dimensions

We consider the wave equation with focusing power nonlinearity. The associated ODE in time gives rise to a self-similar solution known as the ODE blowup. We prove the nonlinear asymptotic stability of this blowup mechanism outside of radial symmetry in all space dimensions and for all superlinear powers. This result covers for the first time the whole energy-supercritical range without symmetry restrictions.
Covid-19 vaccines elicit effective IgG responses in an elderly thymus cancer patient with chemotherapy

ABSTRACT The rising need for repeated booster vaccinations against SARS-CoV-2 infections raises the question of whether chronic immunosuppressive chemotherapies influence the efficacy of vaccination. Here, we present the case of a 70-year-old post-thymoma surgery patient who received Vepesid (etoposide, Xediton Pharmaceuticals Inc) chemotherapy for six months before vaccination with Comirnaty (Pfizer-BioNTech COVID-19 mRNA Vaccine). The first two vaccinations elicited only minimal increases of IgG antibodies specific against the receptor-binding domain (RBD) on the spike protein (S1), while the third vaccination was effective in providing high, slowly subsiding antibody titers over a 7-month period. The patient also developed a cellular immune response after the third vaccination. Also, measuring of anti-polyethylene glycol (PEG) IgM titers before and after vaccinations showed no immunogenicity for PEG. Later, a single dose of Sinopharm (China National Pharmaceutical Group) inactivated virus-type vaccine was administered, which also modestly increased the level of IgG. A symptomless COVID-19 infection, however, greatly increased the serum level of anti-RBD IgG, which later subsided. This case confirms that an effective immune response can be achieved with a series of COVID-19 vaccinations despite cytostatic treatment in an old thymus cancer surviving patient in the absence of adverse reactions.
Chinese Open Instruction Generalist: A Preliminary Release

Instruction tuning is widely recognized as a key technique for building generalist language models, which has attracted the attention of researchers and the public with the release of InstructGPT~\citep{ouyang2022training} and ChatGPT\footnote{\url{https://chat.openai. com/}}. Despite impressive progress in English-oriented large-scale language models (LLMs), it is still under-explored whether English-based foundation LLMs can perform similarly on multilingual tasks compared to English tasks with well-designed instruction tuning and how we can construct the corpora needed for the tuning. To remedy this gap, we propose the project as an attempt to create a Chinese instruction dataset by various methods adapted to the intrinsic characteristics of 4 sub-tasks. We collect around 200k Chinese instruction tuning samples, which have been manually checked to guarantee high quality. We also summarize the existing English and Chinese instruction corpora and briefly describe some potential applications of the newly constructed Chinese instruction corpora. The resulting \textbf{C}hinese \textbf{O}pen \textbf{I}nstruction \textbf{G}eneralist (\textbf{COIG}) corpora are available in Huggingface\footnote{\url{https://huggingface.co/datasets/BAAI/COIG}} and Github\footnote{\url{https://github.com/BAAI-Zlab/COIG}}, and will be continuously updated.
Effect of intravenous iron replacement on recurrent heart failure hospitalizations and cardiovascular mortality in patients with heart failure and iron deficiency: A Bayesian meta‐analysis

Iron deficiency is common in patients with heart failure (HF) and reduced ejection fraction (HFrEF) and is associated with a poor prognosis. Whether intravenous iron replacement improves recurrent HF hospitalizations and cardiovascular mortality of these patients is uncertain although several trials were conducted. Moreover, none of the trials were powered to assess the effect of intravenous iron in clinically important subgroups. Therefore, we conducted a Bayesian analysis to derive precise estimates of the effect of intravenous iron replacement on recurrent HF hospitalizations and cardiovascular mortality in iron‐deficient HFrEF patients using consistent subgroup definitions across trials.
Affine Isoperimetric Inequalities for Higher-Order Projection and Centroid Bodies

In 1970, Schneider generalized the difference body of a convex body to higher-order, and also established the higher-order analogue of the Rogers-Shephard inequality. In this paper, we extend this idea to the projection body, centroid body, and radial mean bodies, as well as prove the associated inequalities (analogues of Zhang's projection inequality, Petty's projection inequality, the Busemann-Petty centroid inequality and Busemann's random simplex inequality). We also establish a new proof of Schneider's higher-order Rogers-Shephard inequality. As an application, a higher-order affine Sobolev inequality for functions of bounded variation is provided.
Unavoidable emergent biaxiality in chiral molecular-colloidal hybrid liquid crystals

Chiral nematic or cholesteric liquid crystals (LCs) are mesophases with long-ranged orientational order featuring a quasi-layered periodicity imparted by a helical configuration but lacking positional order. Doping molecular cholesteric LCs with thin colloidal rods with a large length-to-width ratio or disks with a large diameter-to-thickness ratio adds another level of complexity to the system because of the interplay between weak surface boundary conditions and bulk-based elastic distortions around the particle-LC interface. By using colloidal disks and rods with different geometric shapes and boundary conditions, we demonstrate that these anisotropic colloidal inclusions exhibit biaxial orientational probability distributions, where they tend to orient with the long rod axes and disk normals perpendicular to the helix axis, thus imparting strong local biaxiality on the hybrid cholesteric LC structure. Unlike the situation in achiral hybrid molecular-colloidal LCs, where biaxial order emerges only at modest to high volume fractions of the anisotropic colloidal particles, the orientational probability distribution of colloidal inclusions immersed in chiral nematic hosts are unavoidably biaxial even at vanishingly low particle volume fractions. In addition, the colloidal inclusions induce local biaxiality in the molecular orientational order of the LC host medium, which enhances the weak biaxiality of the LC in a chiral nematic phase coming from the symmetry breaking caused by the presence of the helical axis. With analytical modeling and computer simulations based on minimizing the Landau de Gennes free energy of the host LC around the colloidals, we explain our experimental findings and conclude that the biaxial order of chiral molecular-colloidal LCs is strongly enhanced as compared to both achiral molecular-colloidal LCs and molecular cholesteric LCs and is rather unavoidable.
