description: Here we investigated the cfRNA expression changes associated with preterm PE and early-onset PE from 917 pregnancies (including 202 cases and 715 controls). We identified 77 differentially expressed genes (DEGs) between normotensive and preterm PE mothers before symptom onset, including messenger RNAs (mRNA), microRNAs (miRNAs) and long noncoding RNAs (lncRNAs). These 77 DEGs were sufficient to separate preterm PE from healthy samples, which were enriched in genes specifically expressed in hepatocytes, endothelial and immune cell types, and tissues that reflect key aspects of PE physiology. Furthermore, we developed two classifiers to predict preterm PE and early-onset PE risk before diagnosis, which outperformed the state-of-the-art methods. We showed that 13 cfRNA signatures combined with two clinical features can robustly predict preterm PE: the area under the curve (AUC) and positive predictive values (PPV) in one independent validation cohort (preterm PE, n = 54; control, n = 234) were 83% and 53%, and those in another independent validation cohort (preterm PE, n = 46; control, n = 151) were 81% and 68%. We also built a risk prediction model for early-onset PE using 13 genes and two clinical features, which had an AUC of 88% and a PPV of 73% in an independent validation cohort (early-onset PE, n = 28; control, n = 234). Moreover, we revealed that the downregulation of miRNAs may play vital roles in PE through the upregulation of PE-relevant target genes. Taken together, we proved that these findings of cfRNA signatures hold great potential for the diagnosis and identification of at-risk pregnancies.

description: The field- and temperature-dependent de Haas-van Alphen oscillations spectrum is studied for an ideal two-dimensional compensated metal whose Fermi surface is made of a linear chain of successive orbits with electron and hole character, coupled by magnetic breakdown. We show that the first harmonics amplitude can be accurately evaluated on the basis of the Lifshits-Kosevich (LK) formula by considering a set of random walks on the orbit network, in agreement with the numerical resolution of semi-classical equations. Oppositely, the second harmonics amplitude does not follow the LK behavior and vanishes at a critical value of the field-to-temperature ratio which depends explicitly on the relative value between the hole and electron effective masses.

description: This article demonstrates the conception of numerical techniques for simulating the flow around a NACA 0012 airfoil oscillating at its quarter-chord point. These simulations solve the physics of the dynamic stall phenomenon on an oscillating airfoil case. To do so, a two-dimensional framework is used to achieve feasible aerodynamic predictions. The simulations are required to test aerodynamic coefficients, corresponding to PIV (particle imaging velocimetry) images acquired experimentally according to the literature. A qualitative and quantitative agreement is expected between the simulation and the experimental results for both cases.
High Resolution Helioseismic Imaging of Subsurface Structures and Flows of A Solar Active Region Observed by Hinode

description: We analyze a solar active region observed by the Hinode CaII H line using the time-distance helioseismology technique, and infer wave-speed perturbation structures and flow fields beneath the active region with a high spatial resolution. The general subsurface wave-speed structure is similar to the previous results obtained from SOHO/MDI observations. The general subsurface flow structure is also similar, and the downward flows beneath the sunspot and the mass circulations around the sunspot are clearly resolved. Below the sunspot, some organized divergent flow cells are observed, and these structures may indicate the existence of mesoscale convective motions. Near the light bridge inside the sunspot, hotter plasma is found beneath, and flows divergent from this area are observed. The Hinode data also allow us to investigate potential uncertainties caused by the use of phase-speed filter for short travel distances. Comparing the measurements with and without the phase-speed filtering, we find out that inside the sunspot, mean acoustic travel times are in basic agreement, but the values are underestimated by a factor of 20-40% inside the sunspot umbra for measurements with the filtering. The initial acoustic tomography results from Hinode show a great potential of using high-resolution observations for probing the internal structure and dynamics of sunspots.

description: Electrohydrodynamic jetting is an industrial practice. In this work, a finite element variational multiscale formulation is developed to stabilise the numerical solution of the electrohydrodynamic flow problem. Particularly, the spatial approximation is delat with, which may suffer instabilities arising from equal interpolation spaces for unknown velocity and pressure, and convection dominant type of flows. This approach grants accurate and stable numerical descriptions of the coupled flows modelled by transport equations.
 Future work is intended to validate the model: the electric current must be estimated with experimental measurements.
A Photometrically and Morphologically Variable Infrared Nebula in L483

description: We present narrow and broad K-band observations of the Class 0/I source IRAS 18148-0440 that span 17 years. The infrared nebula associated with this protostar in the L483 dark cloud is both morphologically and photometrically variable on a time scale of only a few months. This nebula appears to be an infrared analogue to other well-known optically visible variable nebulae associated with young stars, such as Hubble's Variable Nebula. Along with Cepheus A, this is one of the first large variable nebulae to be found that is only visible in the infrared. The variability of this nebula is most likely due to changing illumination of the cloud rather than any motion of the structure in the nebula. Both morphological and photometric changes are observed on a time scale only a few times longer than the light crossing time of the nebula, suggesting very rapid intrinsic changes in the illumination of the nebula. Our narrow-band observations also found that H_2 knots are found nearly twice as far to the east of the source as to its west, and that H_2 emission extends farther east of the source than the previously known CO outflow.

We estimated the higher order momenta of the initial distribution of density fluctuations, investigated the redshift evolution of the non-linear power spectrum and estimated the discrepancy introduced by the primordial non-Gaussianity in the non-linear power spectrum.

description: An N-body code containing live stellar evolution through combination of the software packages NBODY6 and STARS is presented. Operational details of the two codes are outlined and the changes that have been made to combine them discussed. We have computed the evolution of clusters of 10 000 stars using the combined code and we compare the results with those obtained using NBODY6 and the synthetic stellar evolution code SSE. We find that, providing the physics package within STARS is set up correctly to match the parameters of the models used to construct SSE, the results are very similar. This provides a good indication that the new code is working well. We also demonstrate how this physics can be changed simply in the new code with convective overshooting as an example. Similar changes in SSE would require considerable reworking of the model fits. We conclude by outlining proposed future development of the code to include more complete models of single stars and binary star systems.

description: To study the onset of a stationary dynamo in the presence of inner or outer walls of various electromagnetic properties, we propose a simple 1D-model in which the flow is replaced by an alpha effect. The equation of dispersion of the problem is derived analytically. It is solved numerically for walls of different thicknesses and of electric conductivity and magnetic permeability different from those of the fluid in motion. We also consider walls in the limit of infinite conductivity or permeability.

Subjects: subject: rap music lyrics
subject: suicide rates

subject: distributed lag model

description: Music lyrics have been long proven to have emotional as well as moral effects on individuals and society. Among genres of music, rap music, being an important part of American music street culture, is special due to the more important role of lyrics in rap songs. This study took rap lyrics as our research focus and tried to explore their mental influence, taking suicide as the target. A total of 5348 popular rap songs from 1995 to 2018 were obtained from the dataset of Billboard music chart, accessed on one Github public source. Suicide rates over the last two decades were available on the website of the National Institute of Mental Health. Moreover, this study also included several factors that were proven to be strong predictors of suicide, such as unemployment rates, divorce rates, GNP, etc. A regular regression model and distributed lag model were constructed. The result suggested rap lyrics, mentioning words related to death and negative emotions, could be significantly correlated to suicide rates in the same period. For one unit increase in rap lyrical mentions percentage, the model estimated suicide rates in the same period will rise by around 108 per 100,000 population. The one-year lag association was also significant based on our distributed lag model, and these relationships were confirmed with the cross-correlation analysis. This association implied that there might be a shared cultural context or societal factors that contribute to both the prevalence of these lyrics and the occurrence of suicide. Therefore, the study suggested that there is an important societal issue at play, which requires further investigation and attention. The findings of this study could inform future research on the cultural and societal factors that contribute to mental health issues and suicide, particularly among vulnerable populations who are more likely to be exposed to rap music.

description: We use I band imaging to perform a variability survey of the 13 Myr-old cluster h Per. We find a significant fraction of the cluster members to be variable. Most importantly, we find that variable members lie almost entirely on the convective side of the gap in the cluster sequence between fully convective stars and those which have a radiative core. This result is consistent with a scenario in which the magnetic field changes topology when the star changes from being fully convective, to one containing a radiative core. When the star is convective the magnetic field appears dominated by large-scale structures, resulting in global-size spots that drive the observed variability. For those stars with radiative cores we observe a marked absence of variability due to spots, which suggests a switch to a magnetic field dominated by smaller-scale structures, resulting in many smaller spots and thus less apparent variability. This implies that wide field variability surveys may only be sensitive to fully convective stars. On the one hand this reduces the chances of picking out young groups (since the convective stars are the lower mass and therefore fainter objects), but conversely the absolute magnitude of the head of the convective sequence provides a straightforward measure of age for those groups which are discovered.

description: Successful software development relies heavily on effectively managing collaboration and technology. However, socio-technical challenges can disrupt team dynamics and contribute to the accumulation of technical debt. Despite the interdisciplinary and diverse nature of teams working on Machine Learning (ML)-enabled systems, research on the socio-technical dynamics within these environments remains limited compared to the extensive focus on technical challenges. This study aims to bridge this gap in understanding socio-technical challenges by exploring the prevalence, evolution, and interrelationships of “community smells” in open-source ML projects. Community smells are measurable social anti-patterns that indicate dysfunctional team interactions and pose risks to effective collaboration. We conducted an empirical study on 188 repositories from the NICHE dataset. Leveraging the CADOCS tool, we identified and analyzed community smells within these repositories. Our analysis focused on three key aspects: (1) the prevalence of community smells, (2) their correlations, and (3) their variations over time. Our findings indicate that while some community smells are more prevalent than others, their overall occurrence remains relatively stable over time. Notably, the community smells of Prima Donna Effects, Sharing Villainy, and Solution Defiance are especially prominent in ML-enabled systems. These insights provide valuable guidance for project managers and team leads in ML-focused communities, helping them mitigate social challenges more effectively, allocate resources more effectively, and improve collaboration and team dynamics.

The geology of the Ecstall-Quall Rivers area, British Columbia.
Creators: name: Padgham, William Albert
Publisher: name: University of British Columbia
Year: 2012

description: The Ecstall-Quaal Rivers area is in the Skeena Mining Division of western British Columbia. The area is underlain by intrusive rocks of the Coast Range Complex Batholith and by older rocks of the Ecstall metamorphic complex, the "Ecstall Septum". A thick group of impure clastic sediments including minor calcareous beds and lenses have undergone extreme dynamothermal metamorphism to give schist, gneiss, quartzite, and marble. Although the amount of cataclastic or dynamic metamorphism has been very high, the minerals present are usually in the lower grades of the amphibolite facies. Retrogressive metamorphism of biotite, and hornblende to sericite and chlorite is common in most of the metamorphic rocks. The original sediments would be those expected under unstable shelf conditions. It appears that the granodiorite which borders the septum on the east and west, has reached its present position by some type of intrusive action. It is certainly not a "metamorphic" or "metasomatic" granite.

description: Obesity is associated with perturbations in incretin production and whole-body glucose metabolism, but the precise mechanism remains unclear. Here, we tested the hypothesis that nicotinamide phosphoribosyltransferase (NAMPT), which mediates the biosynthesis of nicotinamide adenine dinucleotide (NAD+), a key regulator of cellular energy metabolism, plays a critical role in obesity-associated intestinal pathophysiology and systemic metabolic complications. To this end, we generated a novel mouse model, namely intestinal epithelial cell-specific Nampt knockout (INKO) mice. INKO mice displayed diminished glucagon-like peptide-1 (GLP-1) production, at least partly contributing to reduced early-phase insulin secretion and postprandial hyperglycemia. Mechanistically, loss of NAMPT attenuated the Wnt signaling pathway, resulting in insufficient GLP-1 production. We also found that diet-induced obese mice had compromised intestinal NAMPT-mediated NAD+ biosynthesis and the Wnt signaling pathway, associated with impaired GLP-1 production and whole-body glucose metabolism, resembling the INKO mice. Finally, administration of a key NAD+ intermediate, nicotinamide mononucleotide (NMN), restored intestinal NAD+ levels and obesity-associated metabolic derangements, manifested by a decrease in ileal Proglucagon expression and GLP-1 production as well as postprandial hyperglycemia in INKO and diet-induced obese mice. Collectively, our study provides mechanistic and therapeutic insights into intestinal NAD+ biology related to obesity-associated dysregulation of GLP-1 production and postprandial hyperglycemia.

description: Objective: To investigate the incidence of anatomical variations of superficial palmar arch in Negro population. Materials and method: A total of 134 upper limbs comprising 74 right and 60 left specimens embalmed with formaldehyde were used for the investigation. The hand was dissected with palmar aponeurosis identified and removed to expose the ulnar and radial arteries. Results: A complete superficial arch was observed in 73.9 % specimens. In 70.1 % cases the superficial branch of the ulnar artery communicated with its radial arterial counterpart. In 3.0 % cases the arch was formed entirely by the ulnar artery while in a single case (0.8 %), a rare pattern was observed in which the superficial palmar branch of the ulnar artery gave rise to the princeps pollicis artery as its terminal branch with the exclusion of radialis indicis that had its origin from deep palmar branch of radial artery. The incomplete arch constituted 26.1 % of the entire palmar arch formation. Conclusion: In our Negro population study, deviation from normal anatomical pattern was common. Therefore, a review of vascular pattern prior to invasive or intervention surgery is strongly recommended to be able to detect anomalies likely to necessitate modification of surgical procedures.

description: We theoretically study classical thermal activation (TA) and macroscopic quantum tunneling (MQT) for a YBCO Josephson junction coupled with an LC circuit. The TA and MQT escape rate are calculated by taking into account the two-dimensional nature of the classical and quantum phase dynamics. We find that the MQT escape rate is largely suppressed by the coupling to the LC circuit. On the other hand, this coupling leads to the slight reduction of the TA escape rate. These results are relevant for the interpretation of a recent experiment on the MQT and TA phenomena in YBCO bi-epitaxial Josephson junctions.

description: We continue the study of the question of when a pseudo-Riemannain manifold can be locally characterised by its scalar polynomial curvature invariants (constructed from the Riemann tensor and its covariant derivatives). We make further use of alignment theory and the bivector form of the Weyl operator in higher dimensions, and introduce the important notions of diagonalisability and (complex) analytic metric extension. We show that if there exists an analytic metric extension of an arbitrary dimensional space of any signature to a Riemannian space (of Euclidean signature), then that space is characterised by its scalar curvature invariants. In particular, we discuss the Lorentzian case and the neutral signature case in four dimensions in more detail.

The geology of Amco Lake, Burnet Creek and Wreck Lake Coppermine River area, N.W.T.
Creators: name: Sheng, Cheng-Chun
Publisher: name: University of British Columbia

description: Two separate areas which are located in the southern portion of the Coppermine River area were surveyed by the author during the summer of 1957. The area under investigation is underlain by the upper part of the Epworth Series and the lower part of the Coppermine River Series. Because of the lack of fossils in these series, they are presumed to be of late Precambrian age. The upper part of Epworth Series is represented by dolomite and interbedded quartzite. The lower part of the Coppermine River Series is represented by a series of basalt flows which are typical tholeiites, and interbedded sandstone in its upper part. A monzonite dyke crosses the basalt flows and sandstone at a high angle and is parallel to the main basaltic dyke swarm seen in the Takiyuak Lake area. The common structural feature is a series of tension faults trending from N10°E to N45°E and N10°W to N20°W, This is believed to have originated by the compressive force from the north induced by the Caledonian movement. The ore minerals, mainly chalcocite, occur in quartz-carbonate veins in feeder dykes and flow tops of basalt. Flakes of native copper are occasionally found in the fractures of the basalt flows.

description: We classify different classes of entangled states arise in a two-qubit system. Some of these classes are of Bell's state types, while others are of the Werner's state types. The degree of entanglement is quantified for different values of the atomic and the cavity parameters. We show that it is possible to generate entangled state with high degree of entanglement by controlling the detuning and the number of photon inside the cavity.
Position of the mandibular foramen in adult male Tanzania mandibles

Subjects: mandibular foramen; occlusal plane; rameal borders

description: Failure of the inferior alveolar nerve block anesthesia is common in various dental operations. Anatomical variations of the location of the inferior alveolar nerve as it enters the mandibular foramen have been implicated as a main cause of these anesthesia failures. The aim of this work was to determine the location of the mandibular foramen in relation to the occlusal plane at the level of mandibular first molar and second premolar - often used as landmarks during the blocking procedure - and to different landmarks on the ramus of the mandible. The study was performed using mandibles from adult black male Tanzanians aged 30-45 years. Measurements were accomplished using two-digit electronic Vernier calipers. The distances were determined from the center of the mandibular foramen to the different reference points. The mandibular foramen was above the occlusal plane at the M1 and PM2 reference points in all the mandibles studied. It was also located about 20 mm and 12 mm from the anterior and posterior borders of the ramus respectively. There was no significant difference between the left and right side in any of the measurements. These results indicate that during anesthetic or other clinical procedures, the clinician can precisely determine the position of neurovascular bundle of the inferior alveolar nerve above the occlusal plane.

Per descrivere un fenomeno singolare come il lampo di raggi gamma registrato dal satellite Swift il 6 giugno del 2006, c'è bisogno di un'ipotesi fuori dagli schemi: a produrre l'evento sarebbe stata la fusione di una stella di neutroni con un buco nero. Nel team di scienziati che la propone, in un articolo su Nature Communications, anche Stefano Covino dell'INAF
