description: The monocarboxylate transporters 8 (MCT8) and 10 (MCT10) are important for thyroid hormone (TH) uptake and signaling. Reduced TH activity is associated with impaired development, weight gain and discomfort. We hypothesized that autoantibodies (aAb) to MCT8 or MCT10 are prevalent in thyroid disease and obesity. Analytical tests for MCT8-aAb and MCT10-aAb were developed and characterized with commercial antiserum. Serum samples from healthy controls, thyroid patients and young overweight subjects were analyzed, and prevalence of the aAb was compared. MCT8-aAb were additionally tested for biological effects on thyroid hormone uptake in cell culture. Positive MCT8-aAb and MCT10-aAb were detected in all three clinical cohorts analyzed. MCT8-aAb were most prevalent in thyroid patients (11.9%) as compared to healthy controls (3.8%) and overweight adolescents (4.2%). MCT8-aAb positive serum reduced T4 uptake in cell culture in comparison to MCT8-aAb negative control serum. Prevalence of MCT10-aAb was highest in the group of thyroid patients as compared to healthy subjects or overweight adolescents (9.0% versus 4.5% and 6.3%, respectively). We conclude that MCT8 and MCT10 represent autoantigens in humans, and that MCT8-aAb may interfere with regular TH uptake and signaling. The increased prevalence of MCT8-aAb and MCT10-aAb in thyroid disease suggests that their presence may be of pathophysiological relevance. This hypothesis deserves an analysis in large prospective studies.

description: The aim of this study was to create a new reliable setup to evaluate commercially available orthodontic wires used during orthodontic treatment. The setup includes various techniques applied for testing metal alloy materials. The materials were tested under extreme conditions to simulate their behavior in the mouth. The alloy composition of each wire was tested. The electrochemical (EC) testing and characterization of the corrosion performance of the wires was calculated by the electrochemical curves at pH = 1 in two different applied potentials to test the reaction of the material. The liquid collected after the EC measurements was analyzed by inductively coupled plasma-mass spectrometry (ICP-MS) to verify the reliability of the EC curves and for a more accurate evaluation of the corrosion behavior of the wires. Therefore, the EC measurements were compared to the actual values obtained from the released ions found in the solution. At the end, a surface analysis was performed to detect corrosion on the wires. In conclusion, this study developed a setup to test and better understand the corrosion behavior and ion release of the orthodontic wires, metal alloy dental materials, and other metals used in the oral cavity. This method can contribute to dental material selection in patients with underlying health conditions.

description: Cadaver dissection remains a cornerstone in the study of anatomical sciences by medical students. However, this activity can cause emotions that may affect learning outcomes. This study, which involved medical students of various cultural backgrounds, assessed their responses to dissection. Medicine I year students (n = 100) at Oakland University William Beaumont School of Medicine were invited to complete a questionnaire after the first week of dissection, and again at the end of the course. The questionnaire asked for demographics, and assessed the students’ appraisal of their dissection experience, cultural influences, coping activities and learning outcomes. After the first week of dissection, most of the students found the experience challenging, stimulating, exciting and informative, rather than nauseating or unbearable. Still, some students found the experience anxiety-provoking, especially when they thought about human mortality. Cultural background influenced the students’ emotional development as they worked through the course. Most of the participants agreed that dissection promotes teamwork, familiarity with the human body, and integration of the theoretical knowledge with practical application. At the end of the course, dissection was significantly less anxiety-provoking, and, interestingly, the study found that culture and religious beliefs became more important to the students. Most students agreed that dissection is important, relevant, and necessary, and has the potential to improve learning outcomes that are essential to the development of physicians. The study suggests that an introductory course in social, behavioral and ethical considerations be presented at the beginning of the medical curriculum.

description: Dimitrios Alexandrou Mavrokordatos was the first regular professor of Anatomy and Physiology of the Hellenic “Othonian” University of Athens. He had completed his studies in Germany and thus he had been chosen to stimulate the empirical physicians of Greece to awaken. He died young, but his passion was so great that he had published a masterpiece in the new Greece, “On the anatomy of the human body”, and left his fortune for his pupils, even though they had rebelled against him sometime before his death. With his teaching and book he established a kind of Greek “nomina anatomica” which formed the basis for medicine in the newly born country.

description: The present article contains the descriptive study of light strange baryons $Λ$, $Σ$, $Ξ$, and $Ω$. The Regge phenomenology with quasi-linear Regge trajectories has been employed and the relations between Regge slopes, intercepts, and baryon masses have been extracted. With the aid of these relations, ground state masses are obtained for $Ξ$ and $Ω$ baryons. Further, the Regge parameters have also been estimated to calculate the excited state masses for $Λ$, $Σ$, $Ξ$, and $Ω$ baryons in both the $(J,M^{2})$ and $(n,M^{2})$ planes. The obtained results are compared with available experimental data and various theoretical approaches. The spin-parity of recently observed light baryons are predicted in this work and our predictions may be useful in future experimental searches of these baryons and their $J^{P}$ assignments.

description: Diabetic retinopathy is characterized by dysfunction of the retinal vascular network, combined with a persistent low-grade inflammation that leads to vision-threatening complications. Netrin-4 (NTN4) is a laminin-related secreted protein and guidance cue molecule present in the vascular basal membrane and highly expressed in the retina. A number of studies inferred that the angiogenic abilities of NTN4 could contribute to stabilize vascular networks and modulate inflammation. Analyzing human specimens, we show that NTN4 and netrin receptors are upregulated in the diabetic retina. We further evaluated a knock-out model for NTN4 undergoing experimental diabetes induced by streptozotocin. We investigated retina function and immune cells in vivo and demonstrated that NTN4 provides a protective milieu against inflammation in the diabetic retina and prevents cytokine production.

description: The role of robotic radiosurgery (RRS) in the treatment of optic nerve sheath meningiomas (ONSM) remains controversial and it is only performed in specialized institutions due to tight dose constraints. We evaluated the effectiveness and safety of RRS in the management of ONSM. Twenty-five patients with 27 ONSM lesions who underwent RRS using the Cyberknife (CK) system were retrospectively analyzed (median age, 47.9 years; 84.0% women). Multisession RRS was used with 4-5 fractions with a cumulative dose of 20.0-25.0 Gy in 84.0% of patients and a single fraction at a dose of 14.0-15.0 Gy in 16% of patients. Prior to RRS, seven (28%) patients experienced blindness on the lesion side. In those patients with preserved vision prior to radiosurgery, the visual acuity remained the same in 90.0% and improved in 10.0% of the patients. Overall local tumor control was 96.0% (mean follow-up period; 37.4 +/- 27.2 months). Neither patient age, previous surgery, or the period from the initial diagnosis to RRS showed a dependency on visual acuity before or after radiosurgery. RRS is a safe and effective treatment for the management of ONSM. Hypofractionation of radiosurgery in patients with preserved vision before CK treatment results in stable or improved vision.
Proactive Model Adaptation Against Concept Drift for Online Time Series Forecasting

description: Time series forecasting always faces the challenge of concept drift, where data distributions evolve over time, leading to a decline in forecast model performance. Existing solutions are based on online learning, which continually organize recent time series observations as new training samples and update model parameters according to the forecasting feedback on recent data. However, they overlook a critical issue: obtaining ground-truth future values of each sample should be delayed until after the forecast horizon. This delay creates a temporal gap between the training samples and the test sample. Our empirical analysis reveals that the gap can introduce concept drift, causing forecast models to adapt to outdated concepts. In this paper, we present Proceed, a novel proactive model adaptation framework for online time series forecasting. Proceed first estimates the concept drift between the recently used training samples and the current test sample. It then employs an adaptation generator to efficiently translate the estimated drift into parameter adjustments, proactively adapting the model to the test sample. To enhance the generalization capability of the framework, Proceed is trained on synthetic diverse concept drifts. Extensive experiments on five real-world datasets across various forecast models demonstrate that Proceed brings more performance improvements than the state-of-the-art online learning methods, significantly facilitating forecast models' resilience against concept drifts.

Thymic artery: uncommon origin from proximal aortic arch or distal ascending aorta

Publisher: name: Italian Journal of Anatomy and Embryology
Year: 2016
Subjects: Neonatal thymus; Aortic arch; Middle thymic artery; Arterial variations

description: Internal thoracic and inferior thyroid arteries mainly supply the thymus. However, very few studies have been reported on the arterial variations of the thymus. The first author, a cardiac surgeon, happened upon a thymic artery arising from either proximal aortic arch or distal ascending aorta in a few cases during routine cardiac surgery in infants and neonates. Hence a study on the prevalence of the variant thymic artery during open heart surgery was contemplated, as knowledge of its presence could avoid its injury during surgical and diagnostic procedures of the region. The prevalence of the variant thymic artery was observed during 100 consecutive cardiac surgeries in infants and neonates. In addition to two branches from internal thoracic and inferior thyroid arteries, a thymic artery originating from the distal ascending aorta or proximal arch was found in 15 (15%) out of 100 patients who underwent open heart surgery for the correction of congenital heart defects. The artery took origin from the anterior surface of aorta, a little to the left. These were small arteries, single in origin, which started at right angles from the aorta and pierced the pericardium at its reflection, from visceral to parietal, to reach the posterior surface of the thymus where they divided into two branches, one for each lobe. Since this variant artery was present in 15% cases, being aware of its presence can help prevent troublesome bleeding during surgical thymectomy, and more importantly, during surgical and diagnostic interventions in the mediastinum.

description: Recurrent laryngeal nerve palsy is a common post-operative complication of many head and neck surgeries. Theoretically, the best treatment to restore partial function to a damaged recurrent laryngeal nerve would be reinnervation of the posterior cricoarytenoid muscle via anastomosis of the recurrent laryngeal and phrenic nerves. The pig is an excellent model of human laryngeal anatomy and physiology but a more thorough knowledge of porcine laryngeal anatomy is necessary before the pig can be used to improve existing surgical strategies, and develop new ones. This study first identifies the three most common recurrent laryngeal nerve branching patterns in the pig. Secondly, this study presents three-dimensional renderings of the porcine larynx onto which the recurrent laryngeal nerve patterns are accurately mapped. Lastly, heat maps are presented to display the spatial variability of recurrent laryngeal nerve trunks and primary branches on each side of 15 subjects (28 specimens). We intend for this study to be useful to groups using a porcine model to study posterior cricoarytenoid muscle reinnervation techniques.

description: We consider the possible existence of a common channel of evolution of binary systems, which results in a gamma-ray burst during the formation of a black hole or the birth of a magnetar during the formation of a neutron star. We assume that the rapid rotation of the core of a collapsing star can be explained by tidal synchronization in a very close binary. The calculated rate of formation of rapidly rotating neutron stars is qualitatively consistent with estimates of the formation rate of magnetars. However, our analysis of the binarity of newly-born compact objects with short rotational periods indicates that the fraction of binaries among them substantially exceeds the observational estimates. To bring this fraction into agreement with the statistics for magnetars, the additional velocity acquired by a magnetar during its formation must be primarily perpendicular to the orbital plane before the supernova explosion, and be large.

description: Two-dimensional lead halide perovskites are promising materials for optoelectronics due to the tunability of their properties with the number of lead halide layers and the choice of an organic spacer. Physical understanding for the rational design of materials primarily requires knowledge of crystal structure. 2D lead halide perovskites are usually prepared in the form of films complicating the experimental determination of structure. To enable theoretical studies of experimentally unresolvable structures as well as high-throughput virtual screening, we present an algorithm for crystal structure prediction of lead halide perovskites. Using automatically prepared classical potential we show that our algorithm enables fast access to a structure that can be used for further first-principles studies.

Interaction between autumnal temperature-photoperiod and experimentally induced transient cold shock influences proliferative activity in the brain of an adult terrestrial heterothermic vertebrate, Rana bergeri (Günther, 1986)

description: It has been shown previously that in adult Rana esculenta, caught in nature, cold-shocked and brain-injured, encephalic cell proliferation is increased when capture and experiment occurred in spring and depressed when they occurred in autumn. Upon exclusive thermal stress cell proliferation appeared weak in spring and intense in autumn. The present study has investigated cold-shocked, but otherwise uninjured Rana bergeri to assess the impact of autumnal environment on encephalic cell proliferation. Lowering temperature - natural or experimental - seemed to exert a mild stimulation on the proliferative activity only in the forebrain. These results complete those previously obtained in spring and appear in substantial agreement with past reports about antithetical interactions between natural (season climate–photoperiod) and experimental (cold stimulus) environmental factors. However, the present results do not seem sufficient to explain the regenerative events described by past authors. A possible explanation of this discrepancy might be that if the spread between the autumnal environmental conditions and the entity of the cold shock is small the latter would be less effective. Alternatively, cold shock may need to be accompanied by further stimuli, such as surgical trauma (partial resection of brain tissue), to achieve extended stimulation and in the absence of those stimuli it would promote cell proliferation only in the forebrain, which is the region best provided with stand-by putative stem cells.

We characterise galaxies as having either a cold or hot IR SED depending upon whether the rest-frame wavelength of their peak IR energy output is above or below 90um. Our work is based on a far-IR selected sample both in the local Universe and at high redshift, the former consisting of IRAS 60um-selected galaxies at z<0.07 and the latter of Spitzer 70um selected galaxies across 0.110^11 Lsun), the majority of which are cold, dominate the IR luminosity density. We therefore infer that cold galaxies dominate the IR luminosity density across the whole 0

description: Quantitative numerical analyses of interacting dilute Bose-Einstein condensates are most often based on semi-classical approximations. Since the complex-valued field-theoretic action of the Bose gas does not offer itself to the direct application of standard Monte Carlo techniques, simulations beyond their scope by now almost exclusively rely on quantum-mechanical techniques. Here we explore an alternative approach based on a Langevin-type sampling in an extended state space, known as complex Langevin (CL) algorithm. While the use of the CL technique has a long-standing history in high-energy physics, in particular in the simulation of QCD at finitebaryon density, applications to ultracold atoms are still in their infancy. Here we examine the applicability of the CL approach for a one- and two-component, three-dimensional non-relativistic Bose gas in thermal equilibrium, below and above the Bose-Einstein phase transition. By comparison with analytic descriptions at the Gaussian level, including Bogoliubov and Hartree-Fock theory, we find that the method allows computing reliably and efficiently observables in the regime of experimentally accessible parameters. Close to the transition, quantum corrections lead to a shift of the critical temperature which we reproduce within the numerical range known in the literature. With this work, we aim to provide a first test of CL as a potential out-of-the-box tool for the simulation of experimentally realistic situations, including trapping geometries and multicomponent/-species models.

A study of the heat budget components for the British Columbia and S.E. Alaska coast
Creators: name: Elliott, James Elliott
Publisher: name: University of British Columbia
Year: 2011

description: Knowledge of the surface heat transfer in coastal inlets would permit studies of their thermal structure and circulation. An assessment is made of data available for calculating the surface heat transfer for the coastal regions of British Columbia and S.E. Alaska. Monthly means of meteorological and oceanographic observations for the years 1961 and 1963 are critically examined for their representativness of conditions that exist over the open water. The location of the observation point is found to be important in choosing values for dew point and wind speed. Formulae for calculating surface heat transfer are examined for their potential applicability to a coastal climate. The calculated net annual surface heat transfer is found to be highest in the southern regions, approximately 90 langleys/day in the Strait of Georgia, and to decrease for more northerly regions, to an approximate balance with no net input in northern Chatham Strait. The annual cycle is found to be strongly modified by fine structure, the radiation balance dominating in summer, the convective losses in winter. Comparison of the calculated surface heat transfer with heat storage indicates that the calculations may be accurate to within 20% of the peak values. The range and shape of the surface temperature cycle was found to reflect the influence of advection, and deep water temperature, as well as the surface heat transfer.

description: This study examined the relationship between trade facilitation and economic growth among the middle-income countries from 2010 to 2020 using 94 countries made up of 48 lower-middle-income countries and 46 upper-middle-income countries. The study utilized both difference and system Generalised Method of Moments (GMM) since the cross-sections (N) were greater than the periods (T). The study found that container port traffic, quality of trade and transport-related infrastructure have a strong influence on imports and exports of goods and national income while trade tariff hurts the growth of the countries. The study also found that most of the trade facilitation indicators indicated a weak positive influence on trade flows and economic growth. Based on these findings, the study recommends that reforms aimed at significantly lowering the costs of trading across borders among middle-income countries should be highly prioritized in policy formulations, with a focus on the export side by reducing at-the-border documentation, time, and real costs of trading across borders while the international organizations should continue to report the set of Trade Facilitation Indicators (TFIs) that identify areas for action and enable the potential impact of reforms to be assessed.

description: Near a gravitating compact object, massive particles traveling along timelike geodesics are gravitationally deflected similarly to light. In this paper, we study the deflection angles of these particles in the strong deflection limit. This analytical approximation applies when particles in unbound orbits approach the compact object very closely, circle around it at a radius close to that of the unstable circular orbit, and eventually escape. While previous studies have provided results for particular metrics, we offer a general solution applicable to any static, spherically symmetric and asymptotically flat spacetime. After briefly reviewing the exact expression for the deflection angle of massive particles, we present a strong deflection limit analysis for this general case. The developed formulas are then applied to three particular metrics: Schwarzschild, Reissner-Nordström and Janis-Newman-Winicour.

description: Intra-system entanglement occurs between non-separable modes within the same system. For optical systems, the various degrees of freedom of light represent different modes, and the potential use of light to create higher dimensional classical entangle states offers a promising potential to drive new technological developments. In this work, we present experimental results demonstrating the orthogonality between transverse orbital angular momentum (t-OAM) of different spatiotemporal topological charges, a previously unverified property of t-OAM. Based on those results, we developed methods to create and characterize a novel family of t-OAM and polarization entangled spatiotemporal structured light. We further provide theoretical analysis to support our study of the entanglement between those modes. By demonstrating the feasibility of leveraging t-OAM as a new family of modes for classical entanglement, our work represents a new advancement towards higher dimensional classical entanglement strategies.

description: The application of gate voltages in heavy metal/ferromagnet/Oxide multilayer stacks has been identified as one possible candidate to manipulate their anisotropy at will. However, this method has proven to show a wide variety of behaviours in terms of reversibility, depending on the nature of the metal/oxide interface and its degree of oxidation. In order to shed light on the microscopic mechanism governing the complex magneto-ionic behaviour in $\text{Ta/CoFeB/}\text{HfO}_2$, we perform ab-initio simulations on various setups comprising $\text{Fe/O, Fe/HfO}_2$ interfaces with different oxygen atom interfacial geometries. After the determination of the more stable interfacial configurations, we calculate the magnetic anisotropy energy on the different unit cell configurations and formulate a possible mechanism that well describes the recent experimental observations in $\text{Ta/CoFeB/}\text{HfO}_2$.

Quantum Riemannian geometry of the discrete interval and q-deformation

description: We solve for quantum Riemannian geometries on the finite lattice interval $\bullet-\bullet-\cdots-\bullet$ with $n$ nodes (the Dynkin graph of type $A_n$) and find that they are necessarily $q$-deformed with $q=e^{\imathπ\over n+1}$. This comes out of the intrinsic geometry and not by assuming any quantum group in the picture. Specifically, we discover a novel `boundary effect' whereby, in order to admit a quantum-Levi Civita connection, the `metric weight' at any edge is forced to be greater pointing towards the bulk compared to towards the boundary, with ratio given by $(i+1)_q/(i)_q$ at node $i$, where $(i)_q$ is a $q$-integer. The Christoffel symbols are also q-deformed. The limit $q\to 1$ likewise forces the quantum Riemannian geometry of the natural numbers $\Bbb N$ to have rational metric multiples $(i+1)/i$ in the direction of increasing $i$. In both cases, there is a unique Ricci-scalar flat metric up to normalisation. Elements of quantum field theory and quantum gravity are exhibited for $n=3$ and for the continuum limit of the geometry of $\Bbb N$. The Laplacian for the scalar-flat metric becomes the Airy equation operator ${1\over x}{d^2\over d x^2}$ in so far as a limit exists. Scaling this metric by a conformal factor $e^{ψ(i)}$ gives a limiting Ricci scalar curvature proportional to ${e^{-ψ}\over x}{d^2 ψ\over d x^2}$.

description: We present first-principles calculations of the dI/dV characteristics of an H2 molecule sandwiched between Au and Pt electrodes in the presence of electron-phonon interactions. The conductance is found to decrease by a few percentage at threshold voltages corresponding to the excitation energy of longitudinal vibrations of the H2 molecule. In the case of Pt electrodes, the transverse vibrations can mediate transport through otherwise non-transmitting Pt $d$-channels leading to an increase in the differential conductance even though the hydrogen junction is characterized predominately by a single almost fully open transport channel. In the case of Au, the transverse modes do not affect the dI/dV because the Au d-states are too far below the Fermi level. A simple explanation of the first-principles results is given using scattering theory. Finally, we compare and discuss our results in relation to experimental data.

description: Recently, whispering gallery modes (WGMs) have attracted considerable attention due to their extensive applications in the development of on-chip microcavities, high-sensitivity sensors, and high-performance lasers. Conventional WGMs are achiral under the time-reversal symmetry, and show high sensitivity to defects in optical devices. Here, we introduce topological physics into photonic cavities and demonstrate the realization of chiral WGMs enabled by photonic Chern insulators. Through comprehensive numerical simulations and experimental measurements, we reveal the critical differences between chiral and achiral WGMs, highlighting the robustness of chiral WGMs even in the presence of defects within the cavities. Our research provides valuable insights into the design of robust WGM cavities and offers a novel platform for exploring light-matter interaction phenomena.

Radio bounds on the mixed dark matter scenarios of primordial black holes and WIMPs

description: We study the synchrotron radio emission in the mixed dark matter scenarios consisting of the primordial black holes (PBHs) and the self-annihilating WIMPs (weakly interacting massive particles). The WIMPs can form the ultracompact minihalos around PBHs and the annihilation enhancement from these dense halos can lead to the efficient synchrotron radiation at the radio frequency in the presence of galactic magnetic fields. The upper bound of PBH fraction with respect to the total dark matter abundance is of order $10^{-8}\sim 10^{-5}$ depending on the electroweak scale WIMP mass ($m_χ=10\sim 1000$ GeV) and the WIMP annihilation channel (e.g. a hadronic $χχ\rightarrow b \bar{b}$ or a leptonic $χχ\rightarrow e^+ e^-$ channel). The PBH contribution to the total dark matter abundance is hence negligible when the other component of dark matter is composed of the conventional electroweak scale WIMPs.

description: We prove the double bubble conjecture in the three-sphere $S^3$ and hyperbolic three-space $H^3$ in the cases where we can apply Hutchings theory: 1) in $S^3$, each enclosed volume and the complement occupy at least 10% of the volume of $S^3$; 2) in $H^3$, the smaller volume is at least 85% that of the larger. A balancing argument and asymptotic analysis reduce the problem in $S^3$ and $H^3$ to some computer checking. The computer analysis has been designed and fully implemented for both spaces.
